[0146] Invention Effects

[0147] The first positioning assembly, as described in this embodiment, moves at least partially relative to the hopper assembly, changing its position relative to the hopper assembly. This allows for the positioning of films of different sizes on the hopper assembly, enabling more accurate positioning of these films for the material handling assembly to pick them up. Similarly, the second positioning assembly moves at least partially relative to the preparation table, changing its position relative to the table. This allows for the positioning of films of different sizes on the preparation table, enabling more accurate positioning of these films for the application assembly to pick them up. The material hopper assembly and the first positioning assembly enable the feeding of films of different sizes and specifications. The material picking assembly picks up the film from the hopper assembly and moves it to the paper-tearing assembly for paper-tearing. The material picking assembly places the film, now with the release paper removed, onto the preparation table. The preparation table and the second positioning assembly ensure that films of different sizes, after the release paper is removed, are placed in a more accurate position so that the application assembly can pick up the film from the preparation table for application. Therefore, films of different sizes and specifications can be fed into the application equipment and applied to the object to be covered, achieving compatibility of the application equipment with various film sizes and specifications. The adaptability to various film sizes and specifications is achieved through movement and adjustment, eliminating the need to change the hardware structure of the application equipment to accommodate different film sizes.

[0205] Currently, new energy batteries are being used more and more widely in daily life and industry. They are not only used in energy storage systems for hydropower, thermal power, wind power, and solar power plants, but also extensively in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in aerospace and other fields. With the continuous expansion of the application areas of power batteries, the market demand is also constantly increasing.

[0206] As part of the inventive concept of this application, before describing the embodiments of this application, it is necessary to analyze the reasons why adhesive application equipment is difficult to be compatible with multiple different sizes in related technologies, and obtain the technical solution of the embodiments of this application through reasonable analysis.

[0207] In related technologies, a hopper assembly is used to store film. The film stored in the hopper assembly is picked up by a material retrieval assembly. The film stored in the hopper assembly needs to be positioned so that the material retrieval assembly can accurately pick up the film stored in the hopper assembly. However, the structure for positioning the film stored in the hopper assembly is fixed, and the corresponding positioning structure cannot be moved or adjusted. This makes it impossible to accurately position and store film of various sizes and specifications on the hopper assembly, and it cannot adapt to the feeding of film of various sizes and specifications. The material preparation table holds film after the release paper has been removed. The application assembly picks up the film from the material preparation table and applies it to the battery cell. The film stored on the material preparation table needs to be positioned so that the application assembly can accurately pick up the film from the material preparation table and apply it to the battery cell. However, the structure for positioning the film on the material preparation table is fixed, and the corresponding positioning structure cannot be moved or adjusted. This makes it impossible to adapt to the positioning and placement of film of various sizes and specifications on the material preparation table. If either the first positioning assembly corresponding to the material hopper assembly or the second positioning assembly corresponding to the material preparation platform cannot adapt to a variety of different sizes of film, the entire adhesive application equipment will be difficult to be compatible with a variety of different sizes of film and will be difficult to apply different sizes of film to the battery cells.

[0208] The solution in this application embodiment can be applied, but is not limited to, to the film 100 applied to the large surface of a battery cell, the film 100 applied to the small surface of a battery cell, or the film 100 applied to the surface of other objects; it is applicable as long as it is an adhesive application to an object surface. The movement of the first positioning assembly 3 stores and positions the film 100 of different sizes on the hopper assembly 2, ensuring accurate positioning of all film 100s of different sizes stored on the hopper assembly 2, facilitating the retrieval assembly 4 to pick up the film 100s from the hopper assembly 2. The movement of the second positioning assembly 7 places and positions the film 100s of different sizes on the preparation platform 6, facilitating the placement assembly 8 to pick up the film 100s from the preparation platform 6. Therefore, the adhesive application equipment of this application can effectively accommodate the application of film 100s of different sizes.

[0209] The battery pack can contain multiple individual cells, which can be connected in series, parallel, or a combination thereof. A combination of series and parallel connections refers to multiple individual cells being connected in both series and parallel configurations. Multiple individual cells can be directly connected in series, parallel, or a combination thereof, and then the entire assembly is placed inside a housing. Alternatively, multiple individual cells can first be connected in series, parallel, or a combination thereof to form battery modules, and then these modules can be connected in series, parallel, or a combination thereof to form a single unit, which is then placed inside a housing. The battery pack may also include other structures; for example, it may include a busbar for electrical connection between the multiple individual cells.

[0210] A battery cell is a basic unit that can convert chemical energy into electrical energy.

[0211] In the embodiments of this application, the battery cell can be a secondary battery, which refers to a battery cell that can be recharged to activate the active materials and continue to be used after the battery cell has been discharged.

[0212] In this embodiment of the application, the battery cell can be a primary battery. A primary battery can be discharged, but it cannot be recharged and reused.

[0213] In the embodiments of this application, the battery cell can be a lithium-ion battery, sodium-ion battery, sodium-lithium-ion battery, lithium metal battery, sodium metal battery, lithium-sulfur battery, magnesium-ion battery, nickel-metal hydride battery, nickel-cadmium battery, lead-acid battery, etc., and the embodiments of this application are not limited to this.

[0214] A film 100 can be adhered to the surface of a battery cell, and multiple battery cells with the film 100 adhered to can be bonded together to form a battery module. For example, the film 100 adhered to the battery cell can be a heat insulation pad.

[0215] It is understood that film 100 is not limited to heat insulation pads; film 100 can be other types of adhesive structures. For example, film 100 may not have heat insulation or heat dissipation functions; film 100 may simply serve to bond two objects together.

[0216] Individual battery cells can be used to make battery modules or battery packs, which are used to supply power to electrical devices.

[0217] Electrical devices are devices that use electrical energy as their energy source to perform corresponding functions by consuming electrical energy. For example, electrical devices can be, but are not limited to, mobile phones, tablets, laptops, electric toys, power tools, electric vehicles, electric cars, ships, spacecraft, etc. Electric toys can include stationary or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc. Spacecraft can include airplanes, rockets, space shuttles, and spacecraft, etc.

[0218] The following description will be based on an embodiment of the electrical device in this application, which is a vehicle.

[0219] One embodiment of this application provides a vehicle that can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid electric vehicle, or a range-extended electric vehicle, etc. A battery pack is installed inside the vehicle, and the battery pack can be located at the bottom, front, or rear of the vehicle. The battery pack can be used to power the vehicle; for example, the battery pack can serve as the vehicle's operating power source. The vehicle may also include a controller and a motor, and the controller can be used to control the battery pack to power the motor. For example, the battery pack can be used to meet the vehicle's power needs during starting, navigation, and driving.

[0220] In some embodiments of this application, the battery pack can not only serve as the operating power source for the vehicle, but also as the driving power source for the vehicle, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle.

[0221] For the adhesive application device described in this application, please refer to [link to relevant documentation]. Figure 1 The system includes a frame 1, a hopper assembly 2, a first positioning assembly 3, a picking assembly 4, a paper-tearing assembly 5, a preparation table 6, a second positioning assembly 7, and a laying assembly 8. The hopper assembly 2 is disposed on the frame 1 and is used to store the film 100. The first positioning assembly 3 is disposed on the hopper assembly 2 and is at least partially movable relative to the hopper assembly 2 to position the film 100 placed in the hopper assembly 2. The picking assembly 4 is disposed on the frame 1 and has a picking section 41 for picking up the film 100 placed in the hopper assembly 2. The picking assembly 4 is arranged vertically relative to the frame 1. The paper-tearing assembly 5 is disposed on the frame 1 and is used to remove the release paper 101 from the film 100 picked up by the picking section 41. The material preparation table 6 is connected to the frame 1. The material preparation table 6 is used to carry the film 100 after removing the release paper 101. The pick-up unit 41 can reciprocate between the material bin assembly 2, the paper tearing assembly 5, and the material preparation table 6. The second positioning assembly 7 is disposed on the material preparation table 6. The second positioning assembly 7 can move at least partially relative to the material preparation table 6 to position the film 100 placed on the material preparation table 6. The application assembly 8 is disposed on the frame 1. The application assembly 8 is used to pick up the film 100 on the material preparation table 6 and apply it.

[0222] Frame 1 refers to the main structure of the adhesive application equipment, which supports the other parts of the equipment.

[0223] The hopper assembly 2 is used to store film 100. Film 100 is loaded into the hopper assembly 2 and awaits retrieval by the retrieval assembly 4.

[0224] For example, film 100 can be a heat insulation pad.

[0225] For example, the film 100 may not have heat insulation or heat dissipation functions; the film 100 serves to bond two objects together.

[0226] The first positioning assembly 3 is a structure used for positioning. The first positioning assembly 3 is mainly used to position the film 100 stored on the hopper assembly 2.

[0227] The material handling assembly 4 is used to pick up and transfer the film 100, and the material handling assembly 4 transfers the picked-up film 100 to the corresponding position.

[0228] Please see Figure 15 The film 100 includes a film body 102 and a release paper 101 attached to the outer surface of the film body 102. The release paper 101 is mainly used to isolate objects with adhesive properties. Exemplarily, one or more sides of the film body 102 are adhesive, and the release paper 101 is attached to the adhesive surface of the film body 102 to prevent the film 100 from accidentally sticking to other objects. When it is necessary to stick the film body 102 to the surface of an object to be adhered to, the release paper 101 is peeled off from the film 100, and the adhesive surface of the film body 102 exposed by peeling off the release paper 101 is adhered to the surface of the object to be adhered to.

[0229] For example, please refer to Figure 15 The surfaces of the film body 102 on both sides are adhesive, and release paper 101 is attached to the adhesive surfaces on both sides of the film body 102.

[0230] The paper-tearing assembly 5 mainly performs the paper-tearing function, used to tear off the release paper 101 of the film 100. The paper-tearing assembly 5 tears off the release paper 101 on at least one side of the film 100.

[0231] Please see Figure 1 The preparation table 6 is used to hold the film 100 with the release paper 101 removed. The laying assembly 8 cannot directly pick up the film 100 from the picking assembly 4. The picking assembly 4 first places the film 100 with the release paper 101 removed on the preparation table 6, and then the laying assembly 8 picks up the film 100 with the release paper 101 removed from the preparation table 6.

[0232] Please see Figure 1 The pickup unit 41 can reciprocate between the hopper assembly 2, the paper tearing assembly 5, and the preparation table 6. The pickup unit 41 is a structure that picks up the film 100 on the picking assembly 4. The pickup unit 41 can reciprocate between the hopper assembly 2, the paper tearing assembly 5, and the preparation table 6, so that the pickup unit 41 can drive the picked-up film 100 to move between the hopper assembly 2, the paper tearing assembly 5, and the preparation table 6.

[0233] For example, the picking unit 41 of the picking assembly 4 picks up the film 100 on the hopper assembly 2. The picking unit 41 of the picking assembly 4 moves the picked-up film 100 to the paper tearing assembly 5. The paper tearing assembly 5 tears off the release paper 101 of the film 100 picked up by the picking unit 41. The picking unit 41 of the picking assembly moves the film 100 with the release paper 101 removed to the material preparation table 6.

[0234] The second positioning assembly 7 is a structure used for positioning. The second positioning assembly 7 is used to position the film 100 on the preparation table 6 after removing the release paper 101.

[0235] The application assembly 8 is used to pick up the film 100 on the preparation table 6 for application. At least one side of the release paper 101 of the film 100 on the preparation table 6 has been removed. The application assembly 8 pastes the film 100 with the release paper 101 removed from the preparation table 6 onto the surface of the object to be applied.

[0236] For example, the object to be attached can be a single battery cell.

[0237] For example, the battery cell is a square battery, and the surface of the object to be attached can be the large surface of the battery cell.

[0238] It should be explained that the "large surface" of a battery cell refers to the outer surfaces on both sides in the thickness direction of the battery cell.

[0239] For example, the battery cell is a square battery, and the surface of the object to be attached can be a small facet of the battery cell.

[0240] It should be explained that the "large surface" of a battery cell refers to the outer surfaces on both sides along the length of the battery cell.

[0241] It is understandable that the object to be glued is not limited to individual battery cells; other objects that require adhesive can also be glued.

[0242] It is understandable that battery cells are not limited to square cells; the shape of a battery cell can be other than square.

[0243] In the adhesive application device of this application embodiment, since the first positioning assembly 3 can move at least partially relative to the hopper assembly 2, the positioning position of the first positioning assembly 3 relative to the hopper assembly 2 changes, thereby enabling the positioning of adhesive sheets 100 of different sizes on the hopper assembly 2. The adhesive sheets 100 of different sizes on the hopper assembly 2 can be positioned more accurately by the first positioning assembly 3, so that the material picking assembly 4 can pick up the adhesive sheets 100 on the hopper assembly 2. Since the second positioning assembly 7 can move at least partially relative to the preparation table 6, the positioning position of the second positioning assembly 7 relative to the preparation table 6 changes, thereby enabling the positioning of adhesive sheets 100 of different sizes on the preparation table 6. The adhesive sheets 100 of different sizes on the preparation table 6 can be positioned more accurately by the second positioning assembly 7, so that the application assembly 8 can pick up the adhesive sheets 100 on the preparation table 6. The material hopper assembly 2 and the first positioning assembly 3 can accommodate the feeding of films 100 of different sizes and specifications. The material picking assembly 4 picks up the films 100 from the material hopper assembly 2 and moves them to the paper-tearing assembly 5 for paper-tearing. The material picking assembly 4 places the films 100 with the release paper 101 removed onto the preparation table 6. The preparation table 6 and the second positioning assembly 7 ensure that films 100 of different sizes and specifications can be placed in a more accurate position after the release paper 101 is removed, so that the application assembly 8 can pick up the films 100 from the preparation table 6 for application. Therefore, films 100 of different sizes and specifications can be fed into the application equipment and applied to the object to be applied, achieving compatibility of the application equipment with multiple films 100 of different sizes and specifications. By adjusting the movement, it can adapt to multiple films 100 of different sizes and specifications without changing the hardware structure of the application equipment to adapt to different sizes of films 100. In addition, the hopper assembly 2, the material picking assembly 4, the paper tearing assembly 5, the material preparation platform 6, and the adhesive application assembly 8 are all located on the frame. The first positioning assembly 3 is located on the hopper assembly 2, and the second positioning assembly 7 is located on the material preparation platform 6. The overall structure of the adhesive application equipment is relatively compact and has a high space utilization rate.

[0244] It is understandable that when film 100 is placed in hopper assembly 2, the difference in the size of film 100 is mainly reflected in the difference in size of film 100 in the direction intersecting the vertical direction.

[0245] For example, please refer to Figures 2-4 , Figure 11 as well as Figure 15 The film 100 is square in shape. When the film 100 is placed in the hopper assembly 2, the thickness direction of the film 100 is roughly arranged along the vertical direction. The length and width directions of the film 100 are perpendicular to the vertical direction. The different size specifications of the film 100 are mainly reflected in the different dimensions of the length and width directions of the film 100.

[0246] For example, the adhesive applicator of this application embodiment can be compatible with square film 100 in the following size ranges: the length of the square film 100 is 0~300mm and the width of the square film 100 is 0~180mm.

[0247] In one embodiment, please refer to Figures 3-7 , Figure 9 ,as well as Figures 11-14 The first positioning assembly 3 includes a first positioning component 31, a second positioning component 32, a first driving device 33, a third positioning component 34, and a second driving device 35. The first positioning component 31 is connected to the hopper assembly 2. The second positioning component 32 is movably disposed on the hopper assembly 2. The first driving device 33 is mounted on the hopper assembly 2 and drives the second positioning component 32 to move along a first direction. The second positioning component 32 and the first positioning component 31 are used to position the film 100 along the first direction. The third positioning component 34 is movably disposed on the hopper assembly 2. The second driving device 35 is mounted on the hopper assembly 2 and drives the third positioning component 34 to move along a second direction. The second direction is intersected with the first direction, and both the first and second directions are intersected with the vertical direction. The third positioning component 34 and the first positioning component 31 are used to position the film 100 along the second direction.

[0248] The first positioning component 31 is connected to the hopper assembly 2. The position of the first positioning component 31 relative to the area on the hopper assembly 2 where the film 100 is stored along the first and second directions will hardly change. The first positioning component 31 can serve as a positioning reference for the film 100 on the hopper assembly 2, making it easier for the material picking assembly 4 to accurately pick up the film 100.

[0249] For example, the length direction of the film 100 is arranged along the second direction, and the width direction of the film 100 is arranged along the first direction.

[0250] In this embodiment, the film 100 is positioned along a first direction by the second positioning component 32 and the first positioning component 31, and along a second direction by the third positioning component 34 and the first positioning component 31. Since both the first and second directions intersect with the vertical direction, the film 100 can be positioned in a plane intersecting with the vertical direction by the first positioning component 31, the second positioning component 32, and the third positioning component 34. The first driving device 33 drives the second positioning component 32 to move along the first direction, thereby accommodating the positioning of films 100 of different sizes in the first direction. The second driving device 35 drives the third positioning component 34 to move along the second direction, thereby accommodating the positioning of films 100 of different sizes in the second direction. Therefore, by moving the second positioning component 32 and the third positioning component 34 in two different directions, films 100 of different sizes can be positioned in a plane intersecting with the vertical direction, so that films 100 of different sizes can be positioned more accurately on the hopper assembly 2, achieving positioning in the entire plane with fewer movement directions.

[0251] For example, please refer to Figures 2-4 ,as well as Figure 11 The first positioning component 31, the second positioning component 32 and the third positioning component 34 can accurately position films 100 of different sizes in a plane perpendicular to the vertical direction.

[0252] It is understood that the embodiments of this application are not limited to the positioning of the film 100 in a plane intersecting the vertical direction by moving the second positioning component 32 and the third positioning component 34 in two directions respectively.

[0253] For example, the first positioning component 31, the second positioning component 32 and the third positioning component 34 can all move relative to the hopper assembly 2.

[0254] For example, one of the first positioning component 31, the second positioning component 32, and the third positioning component 34 moves while the other two of the three remain stationary relative to the hopper assembly 2, which can accommodate the positioning of films 100 of different sizes in one direction.

[0255] The hopper assembly 2 in this application embodiment can have various structural forms.

[0256] In one embodiment, please refer to Figure 2 and Figure 3The hopper assembly 2 includes a first driver 21, a turntable 22, and a main hopper 23. The first driver 21 is mounted on the frame 1. The turntable 22 is mounted on the first driver 21, and the first driver 21 drives the turntable 22 to rotate. The plane coinciding with the rotation center line of the turntable 22 is a reference surface 221. First positioning assemblies 3 are provided on opposite sides of the reference surface 221. The first positioning assembly 31 is connected to the turntable 22. The second positioning assembly 32 and the third positioning assembly 34 are movably mounted on the turntable 22. The first driving device 33 and the second driving device 35 are both mounted on the turntable 22. On opposite sides of the reference surface 221 corresponding to the turntable 22, one side is the feeding side for feeding the film 100, and the other side is the picking side for picking up the film 100. The main hopper 23 is located on the turntable 22. The film 100 stored in each main hopper 23 is positioned by the corresponding first positioning assembly 3.

[0257] The first driver 21 is used to provide power to the turntable 22 to drive the turntable 22 to rotate.

[0258] For example, the first driver 21 can be a motor.

[0259] For example, the first actuator 21 may be a rotary cylinder.

[0260] The first positioning component 31 is connected to the turntable 22. The first positioning component 31 hardly moves relative to the turntable 22. The first positioning component 31 serves as the positioning reference for the film 100 stored on the main compartment 23.

[0261] The second positioning component 32 and the third positioning component 34 move relative to the turntable 22 in two different directions to accommodate films 100 of different sizes.

[0262] In this embodiment, main chambers 23 are provided on both opposite sides of the reference surface 221. One side of the opposite sides of the reference surface 221 is the feeding side, where the film 100 is fed into the main chamber 23. The other side of the opposite sides of the reference surface 221 is the picking side, where the picking assembly 4 picks up the film 100 from the main chamber 23 on the picking side. When the main chamber 23 on the picking side needs to feed film 100, the first driver 21 drives the turntable 22 to rotate, rotating the main chamber 23 that has been fed on the feeding side to the picking side for picking, and the main chamber 23 on the picking side that needs to be fed to the feeding side to the feeding side for feeding. Through the rotation of the turntable 22, the picking and feeding of the two main chambers 23 do not affect each other, and the picking and feeding can be operated in parallel, improving the working efficiency and production cycle of the adhesive application equipment. The first positioning assembly 3 corresponding to each main compartment 23 can position films 100 of different sizes stored on the main compartment 23 of the corresponding side, and the main compartment 23 of each side and the first positioning assembly 3 are compatible with films 100 of different sizes on the corresponding side.

[0263] It is understood that the hopper assembly 2 is not limited to a structure where the turntable 22 rotates. For example, the hopper assembly 2 may not include the turntable 22, and the feeding position of the hopper assembly 2 may be used for material retrieval.

[0264] In one embodiment, please refer to Figures 2-4 , Figure 6 ,as well as Figure 14 The hopper assembly 2 also includes a partition 25. The center plane of the partition 25 in the width direction coincides with the reference plane 221.

[0265] In this embodiment, the hopper assemblies 2 on both sides of the reference surface 221 are separated by a partition 25, thereby reducing the mutual interference between the hopper assemblies 2 on both sides of the reference surface 221.

[0266] In one embodiment, please refer to Figure 2 and Figure 3 Each main compartment 23 includes a plurality of hopper assemblies 231 arranged sequentially along a first direction, the hopper assemblies 231 being used to store film 100.

[0267] In this embodiment, multiple hopper assemblies 231 feed in parallel, which can improve the feeding efficiency of the film 100. The multiple hopper assemblies 231 are arranged sequentially along the first direction, which facilitates the positioning of the film 100 on the hopper assembly 231 by the second positioning assembly 32 that moves along the first direction on each side.

[0268] For example, please refer to Figure 2 The four hopper components 231 are arranged along the first direction.

[0269] Understandably, the film 100 is stored in the hopper assembly 231, and the hopper assembly 231 should support the entire film body 102 as much as possible and avoid the film body 102 from hanging out of the hopper assembly 231 as much as possible.

[0270] In one embodiment, please refer to Figures 9-13 The hopper assembly 231 has a first clearance area 2311 extending along a first direction. The second positioning assembly 32 includes a first mounting base 321 and a first positioning post 322. The projection area of ​​the first mounting base 321 along the vertical direction is a first shadow area, and the projection area of ​​the hopper assembly 231 along the vertical direction is a second shadow area. The first shadow area overlaps with a plurality of second shadow areas arranged along the first direction. The first mounting base 321 is disposed below the turntable 22, and the first driving device 33 drives the first mounting base 321 to move along the first direction. The first positioning post 322 is connected above the first mounting base 321 and passes through the turntable 22. A first positioning post 322 is provided at a corresponding position in each hopper assembly 231, and the first positioning post 322 can move within the corresponding first clearance area 2311.

[0271] The first clearance zone 2311 is the space to avoid the first positioning post 322. The first positioning post 322 moves within the first clearance zone 2311 to reduce the possibility of interference between the first positioning post 322 and the hopper assembly 231.

[0272] The first shadow area overlaps with multiple second shadow areas arranged along the first direction. The first mounting base 321 extends along the first direction to the corresponding positions of multiple hopper components 231. A first positioning post 322 is provided at the corresponding position of each hopper component 231, and these first positioning posts 322 are all connected above the first mounting base 321. The first driving device 33 drives the first mounting base 321 to move along the first direction. Through the first mounting base 321 extending along the first direction to the corresponding positions of multiple hopper components 231, the first positioning posts 322 at the corresponding positions of each hopper component 231 are moved together.

[0273] In this embodiment, since the first mounting base 321 is located below the turntable 22, the possibility of interference between the first mounting base 321 and the hopper assembly 231 at the corresponding positions of the multiple hopper assemblies 231 extending along the first direction can be reduced. Even if the first shadow area overlaps with the multiple second shadow areas arranged along the first direction, the first mounting base 321 located below the turntable 22 will not block the film 100 on the hopper assembly 231, which is beneficial for the material picking assembly 4 to pick up the film 100 on the hopper assembly 231. Since both the first and second directions are arranged intersecting with the vertical direction, the first positioning post 322 and the film 100 on the hopper assembly 231 are positioned along the first direction. The first positioning post 322 needs to extend upward from the first mounting base 321 to the top of the hopper assembly 231. The first positioning post 322 moves within the first clearance area 2311, allowing it to move along the first direction from the edge of the hopper assembly 231 towards the center, accommodating the positioning of films 100 of different sizes along the first direction. By extending the first mounting base 321 along the first direction to the corresponding positions of multiple hopper assemblies 231, the first positioning post 322 at the corresponding positions of each hopper assembly 231 moves together, and all hopper assemblies 231 are positioned together along the first direction, which facilitates rapid adjustment to accommodate films 100 of different sizes along the first direction.

[0274] For example, please refer to Figure 5 and Figure 13 The first positioning post 322 includes a post body 3221 and a base 3222. The base 3222 is connected above the first mounting base 321 and passes through the turntable 22. The post body 3221 is connected above the base 3222.

[0275] It is understood that the embodiments of this application are not limited to the first driving device 33 driving the first mounting base 321 to move the first positioning posts 322 together. For example, each first positioning post 322 corresponds to a first mounting base 321 and a first driving device 33, and each first driving device 33 drives the corresponding first mounting base 321 and first positioning post 322 to move, and each first positioning post 322 moves to position the film 100.

[0276] It is understandable that when the film 100 stored in the hopper assembly 231 is suspended outside the hopper assembly 231, the hopper assembly 231 may not be provided with a first clearance zone 2311.

[0277] In one embodiment, please refer to Figure 1 ,as well as Figures 4-8 The adhesive applicator also includes a detector 9. The first mounting base 321 has a first clearance cavity 3211, the turntable 22 has a second clearance cavity 222, and the hopper assembly 231 has a third clearance cavity 2312. The detector 9 has a detection unit 91 for generating a detection signal. Projected in the vertical direction, the projection areas of the first clearance cavity 3211, the second clearance cavity 222, and the third clearance cavity 2312 all cover the projection area of ​​the detection unit 91. The detection signal of the detection unit 91 passes through the first clearance cavity 3211, the second clearance cavity 222, and the third clearance cavity 2312. When the turntable 22 rotates, the detector 9 is located below the first mounting base 321, and the detector 9 is disengaged from the turntable 22.

[0278] Detector 9 is used to detect whether film 100 is stored on hopper assembly 231. When film 100 is placed on hopper assembly 231, its position on hopper assembly 231 will cover the third clearance area 621. The detection signal of detector 9 is blocked by film 100 stored on hopper assembly 231, thus enabling detector 9 to identify that film 100 is stored on hopper assembly 231. When film 100 is not stored on hopper assembly 231, the detection signal passing through the third clearance area 621 will not be blocked by film 100, thus enabling detector 9 to identify that film 100 is not stored on hopper assembly 231.

[0279] For example, detector 9 is a photoelectric sensor, and the detection signal emitted by detection unit 91 is a light signal. When the light signal emitted by detector 9 passes through the third clearance area 621 and is blocked by film 100, the light signal is reflected back to detector 9 and received by detector 9, thereby identifying that film 100 is stored on the discharge hopper assembly 231. When the light signal emitted by detector 9 passes through the third clearance area 621 without being blocked, detector 9 does not receive the reflected light signal, thereby identifying that film 100 is not on the discharge hopper assembly 231.

[0280] In this embodiment, the detector 9 is located below the first mounting base 321. The detector 9 will hardly obstruct the film 100 on the hopper assembly 231, reducing the possibility of interference between the detector 9 and the material handling assembly 4, and facilitating the material handling assembly 4 to pick up the film 100. The detector 9 is located below the first mounting base 321 and is detached from the turntable 22. The detector 9 will not rotate with the turntable 22, which can reduce the risk of the signal line of the detector 9 becoming tangled. Since the projection areas of the first clearance cavity 3211, the second clearance cavity 222, and the third clearance cavity 2312 all cover the projection area of ​​the detection unit 91, the detection signal emitted by the detection unit 91 can pass through the first clearance cavity 3211 of the first mounting base 321, the second clearance cavity 222 of the turntable 22, and the third clearance cavity 2312 of the hopper assembly 231 to reach the area on the hopper assembly 231 used to store the film 100, thereby detecting whether the film 100 is stored on the hopper assembly 231.

[0281] In one embodiment, please refer to Figure 1 ,as well as Figures 4-8 Detectors 9 are provided on both sides of the reference surface 221. The detectors 9 corresponding to the main compartment 23 on the feeding side of the two main compartments 23 are connected to the frame 1. The hopper assembly 231 has a bearing surface 2313 for bearing the film 100. The hopper assembly 2 also includes a lifting device 24 provided on the frame 1. The lifting device 24 is located at the position corresponding to the main compartment 23 on the picking side of the two main compartments 23. The lifting device 24 is used to drive the hopper assembly 231 on the picking side to move at least partially so that the bearing surface 2313 is raised and lowered. The detectors 9 corresponding to the main compartment 23 on the picking side are installed on the lifting device 24. The lifting device 24 drives the detectors 9 to rise and fall. When the lifting device 24 is lowered to the lowest position, the lifting device 24 and the corresponding detectors 9 are both located below the first mounting base 321.

[0282] The bearing surface 2313 of the hopper assembly 231 can be raised and lowered. The bearing surface 2313 of the hopper assembly 231 on the feeding side is approximately at the lowest position that the bearing surface 2313 can descend. Multiple film sheets 100 are stacked sequentially on the bearing surface 2313 in the vertical direction to complete the feeding. After the hopper assembly 231 has completed feeding, it is rotated to the picking side by the turntable 22. Each time the picking part 41 of the picking assembly 4 picks up a film sheet 100, the bearing surface 2313 of the corresponding hopper assembly 231 moves up by approximately the distance of one film sheet 100 under the push of the lifting device 24, so that the picking assembly 4 can continue to pick up film sheets 100 at approximately the same position.

[0283] For example, the lifting device 24 can be a cylinder or an electric push rod.

[0284] In this embodiment, the detector 9 connected to the frame 1 hardly moves relative to the frame 1, and the signal line of the detector 9 has little sway, which helps to reduce the wear of the signal line and the interference between the signal line and other components. When the lifting device 24 is lowered to the lowest position, both the lifting device 24 and the detector 9 are located below the first mounting base 321. In this case, the detection signal of the detector 9 can pass through the first clearance cavity 3211, the second clearance cavity 222 and the third clearance cavity 2312 to detect the film 100. The lifting part of the lifting device 24 can pass through the first clearance cavity 3211 and the second clearance cavity 222 to contact the hopper assembly 231, so as to push the bearing surface 2313 to rise and fall. The detector 9 is installed on the lifting device 24. The first avoidance cavity 3211 and the second avoidance cavity 222 avoid the lifting part of the lifting device 24 by avoiding the detection signal of the detector 9. The first mounting base 321 and the turntable 22 no longer need to open up the space to avoid the lifting device 24 by removing materials, which helps to simplify the structure of the first mounting base 321 and the turntable 22 and increase the load-bearing strength of the first mounting base 321 and the turntable 22.

[0285] For example, please refer to Figure 2 , Figure 4 , Figure 6 and Figure 7 Each hopper assembly 231 is equipped with a corresponding lifting device 24.

[0286] It is understood that the positional arrangement of the detectors 9 in this embodiment is not limited to the positions described above. Exemplarily, both detectors 9 are connected to the frame 1. Exemplarily, the detectors 9 can be mounted on the turntable 22.

[0287] In one embodiment, please refer to Figures 9-11 ,as well as Figure 14 The hopper assembly 231 has a second clearance area 2314, and the third positioning assembly 34 includes a second mounting base 341 and a positioning post assembly 342. The second mounting base 341 is disposed on the turntable 22, and the second drive device 35 drives the second mounting base 341 to move along a second direction. The positioning post assembly 342 is connected above the second mounting base 341, and a positioning post assembly 342 is provided at a corresponding position in each hopper assembly 231. The positioning post assembly 342 can move within the corresponding second clearance area 2314.

[0288] The second clearance zone 2314 is a space for avoiding the positioning post device group 342. The positioning post device group 342 moves within the second clearance zone 2314 to reduce the possibility of interference between the positioning post device group 342 and the hopper assembly 231 during the movement.

[0289] The second mounting base 341 extends along the first direction to positions corresponding to multiple hopper components 231, and a positioning post device group 342 is provided at each position corresponding to each hopper component 231. The second driving device 35 drives the second mounting base 341 to move along the second direction, thereby driving the positioning post device group 342 at each position corresponding to each hopper component 231 to move together along the second direction.

[0290] In this embodiment, since both the first and second directions are arranged intersecting the vertical direction, the positioning post assembly 342 and the film 100 on the hopper assembly 231 are positioned at least along the second direction. The positioning post assembly 342 needs to extend upward from the second mounting base 341 to the top of the hopper assembly 231. The positioning post assembly 342 moves within the second clearance area 2314, allowing it to move along the second direction from the edge of the hopper assembly 231 towards the center, accommodating the positioning of films 100 of different sizes along the second direction. By extending along the first direction to the corresponding positions of multiple hopper assemblies 231, the second mounting base 341 moves the positioning post assembly 342 at the corresponding positions of each hopper assembly 231 together, positioning each hopper assembly 231 together along the second direction. This facilitates rapid adjustment to accommodate films 100 of different sizes along the second direction.

[0291] It is understandable that when the film 100 stored in the hopper assembly 231 is suspended outside the hopper assembly 231, the hopper assembly 231 may not be provided with a second clearance zone 2314.

[0292] It is understood that each positioning post device group 342 is provided with a corresponding second mounting base 341 and a second driving device 35. Each second driving device 35 drives the corresponding second mounting base 341 and positioning post device group 342 to move, and each positioning post device group 342 moves along the second direction to position the film 100.

[0293] In one embodiment, please refer to Figure 11 and Figure 15 The release paper 101 of the film 100 has an ear 1011 that protrudes from the film body 102.

[0294] In this embodiment, the protruding ear 1011 facilitates the paper tearing assembly 5 to hold the release paper 101, and the paper tearing assembly 5 tears the release paper 101 off the film body 102 by holding the protruding ear 1011 of the release paper 101.

[0295] In one embodiment, please refer to Figure 11 and Figure 15The ear portions 1011 on opposite sides of the film body 102 are arranged at intervals along the projection area of ​​the film body 102 in the thickness direction.

[0296] For example, please refer to Figure 11 and Figure 15 The projection areas formed by projecting the two ear portions 1011 along the thickness direction of the film body 102 are arranged at intervals along the length direction of the film body 102.

[0297] For example, please refer to Figure 3 and Figure 11 When the film 100 is placed in the hopper assembly 231, the two ear parts 1011 are arranged at intervals along the second direction.

[0298] In one embodiment, please refer to Figures 9-11 ,as well as Figure 14 The hopper assembly 231 has a bearing surface 2313 for bearing the film 100. The second clearance area 2314 includes a first sub-area 23141 and a second sub-area 23142, both extending along a second direction. The first sub-area 23141 is located on the side of the second sub-area 23142 facing the corresponding bearing surface 2313 along a first direction. The positioning post device group 342 includes a second positioning post 3421 and a third positioning post 3422. The second positioning post 3421 is connected above the second mounting base 341. A second positioning post 3421 is provided at a corresponding position in each hopper assembly 231. The second positioning post 3421 is movable within the first sub-area 23141. The third positioning post 3422 is connected above the second mounting base 341. A third positioning post 3422 is provided at the corresponding position of each hopper assembly 231. The third positioning post 3422 can move within the second sub-area 23142. The third positioning post 3422 is located on the side of the second positioning post 3421 away from the reference surface 221 along the second direction.

[0299] The first sub-area 23141 is located on the side of the second sub-area 23142 facing the corresponding bearing surface 2313 along the first direction. The second sub-area 23142 is closer to the edge of the hopper assembly 231 along the first direction than the first sub-area 23141. Correspondingly, the second sub-area 23142 is closer to the edge of the film 100 stored in the hopper assembly 231 along the first direction than the first sub-area 23141.

[0300] In this embodiment, the second positioning post 3421 is movable within the first sub-region 23141, and the third positioning post 3422 is movable within the second sub-region 23142. The third positioning post 3422 is located on the side of the second positioning post 3421 facing away from the reference surface 221 along the second direction. The second positioning post 3421 is located at the edge of the film 100 stored in the hopper assembly 231 along the second direction. The movable second positioning post 3421 can perform lateral positioning on the film 100 with different dimensions along the second direction. The second positioning post 3421 and the film 100 are positioned by abutment along the second direction. The second positioning post 3421 is movable within the first sub-region 23141. The second positioning post 3421 can move from the edge of the hopper assembly 231 along the second direction to the middle part of the hopper assembly 231 to accommodate the film 100 with different dimensions along the second direction. The third positioning post 3422 is located at the edge of the film 100 stored in the hopper assembly 231 along the first direction. The third positioning post 3422 and the film 100 are positioned by abutting against each other along the first direction. The third positioning post 3422 is located between the two side ears 1011 of the film 100 stored in the hopper assembly 231. The third positioning post 3422 moves along the second direction to accommodate film 100s with different sizes of spacing between the two side ears 1011 along the second direction. By avoiding the second positioning post 3421 by the first sub-region 23141, the possibility of interference between the second positioning post 3421 and the hopper assembly 231 can be reduced. By avoiding the third positioning post 3422 by the second sub-region 23142, the possibility of interference between the third positioning post 3422 and the hopper assembly 231 can be reduced.

[0301] The structure of the positioning post device group 342 in this application embodiment is not limited. For example, the positioning post device group 342 may not include the third positioning post 3422.

[0302] In one embodiment, please refer to Figure 3 , Figure 10 , Figure 11 and Figure 14 The length of the bearing surface 2313 is arranged along the second direction, and the second positioning column 3421 is flat.

[0303] The length direction of the bearing surface 2313 is arranged along the second direction, and the length direction of the film 100 placed on the bearing surface 2313 is also arranged along the second direction. The film 100 of different sizes and specifications has a large dimensional variation in the length direction of the film 100.

[0304] In this embodiment, the second positioning post 3421 is flat and contacts the film 100 along the second direction. The second positioning post 3421 can drive the film 100 to move relatively smoothly over a long distance along the second direction to position the film 100 in the corresponding position. During the process of the film 100 being pushed and positioned by the second positioning post 3421, the possibility of the film 100 being pushed off course by the second positioning post 3421 is reduced.

[0305] The shape of the second positioning post 3421 in this application embodiment is not limited. Exemplarily, the second positioning post 3421 is cylindrical.

[0306] The first positioning post 322 and the third positioning post 3422 in this embodiment can both be cylindrical.

[0307] In one embodiment, please refer to Figure 14 The positioning post assembly 342 also includes a reinforcing rib 3423, which is connected to the second mounting base 341 and the flat second positioning post 3421 respectively. The reinforcing rib 3423 is located on the side of the second positioning post 3421 facing the reference surface 221 along the second direction.

[0308] Each hopper assembly 231 has multiple film sheets 100 stacked sequentially in the vertical direction on its bearing surface 2313. Each film sheet 100 needs to be positioned by a second positioning post 3421 along a second direction. The second positioning post 3421 extends upwards from the second mounting base 341 to a considerable height. The flat second positioning post 3421 is relatively thin to reduce its weight.

[0309] In this embodiment, the reinforcing ribs 3423 are connected to the second mounting base 341 and the flat second positioning post 3421 respectively, which enhances the strength of the thinner and taller second positioning post 3421 and increases its resistance to deformation. During the process of the second positioning post 3421 pushing the film 100 to move along the second direction, the bending deformation of the second positioning post 3421 can be reduced, which is conducive to the second positioning post 3421 positioning the film 100 more accurately along the second direction.

[0310] The structure of the positioning post device group 342 in this application embodiment is not limited. For example, the positioning post device group 342 may not have the reinforcing rib 3423.

[0311] In one embodiment, please refer to Figure 14 The second positioning post 3421 is located between the reference surface 221 and the first positioning component 31 along the second direction, and the reinforcing rib 3423 is located on the side of the second positioning post 3421 facing the reference surface 221 along the second direction.

[0312] The second positioning post 3421 is located between the reference surface 221 and the first positioning component 31 along the second direction. When the film 100 is stored in the hopper component 231, the second positioning post 3421 is located between the film 100 and the reference surface 221 along the second direction, and the second positioning post 3421 and the film 100 are positioned by abutting against each other along the second direction. The direction of the reaction force of the film 100 on the second positioning post 3421 is from the second positioning post 3421 to the reference surface 221.

[0313] In this embodiment, the reinforcing rib 3423 is located on the side of the second positioning post 3421 facing the reference surface 221 along the second direction. The supporting force of the reinforcing rib 3423 on the second positioning post 3421 and the reaction force of the film 100 on the second positioning post 3421 are opposite in direction, which is beneficial for the reinforcing rib 3423 to better support the second positioning post 3421 and enhance the deformation resistance of the second positioning post 3421.

[0314] The position of the reinforcing rib 3423 in this embodiment is not limited. For example, the reinforcing rib 3423 may be located on the side of the second positioning post 3421 facing away from the reference surface 221 along the second direction.

[0315] In one embodiment, please refer to Figure 10 The hopper assembly 231 includes a guiding mechanism 2315 and a support mechanism 2316 disposed on the guiding mechanism 2315. The support mechanism 2316 is used to store the film 100. The guiding mechanism 2315 guides the support mechanism 2316 to move in the vertical direction. The arrangement direction of the guiding mechanism 2315 and the support mechanism 2316 is intersecting with the vertical direction.

[0316] The support mechanism 2316 is used to store the film 100 and serves to support the film 100.

[0317] For example, please refer to Figure 10 The bearing surface 2313 is formed on the support structure 2316.

[0318] The guide mechanism 2315 and the support mechanism 2316 are arranged in a cross direction with the vertical direction. In the direction that intersects with the vertical direction, the guide mechanism 2315 is located on one side of the support mechanism 2316, and the bottom of the support mechanism 2316 is suspended.

[0319] In this embodiment, the guide mechanism 2315 guides the support mechanism 2316 to move vertically. As the support mechanism 2316 moves downward, multiple film sheets 100 are stacked sequentially on the support mechanism 2316, completing the film sheet 100 loading. During the material handling process, each time the material handling assembly 4 picks up a film sheet 100, the guide mechanism 2315 guides the support mechanism 2316 to move upward by approximately one film sheet 100, so that the uppermost film sheet 100 stored on the support mechanism 2316 is positioned as close as possible to the position to be picked up by the picking part 41 of the material handling assembly 4, facilitating the material handling assembly 4 to pick up the film sheet 100. The guide mechanism 2315 and the support mechanism 2316 are arranged in a cross direction with the vertical direction. The bottom of the support mechanism 2316 is suspended. During the downward movement of the support mechanism 2316, the film 100 stored on the support mechanism 2316 will not interfere with the guide mechanism 2315, and the film 100 stored on the support mechanism 2316 will not be lifted up by the guide mechanism 2315.

[0320] For example, please refer to Figure 2 , Figure 4 , Figure 6 and Figure 7 Each lifting device 24 is located below the corresponding support mechanism 2316.

[0321] In one embodiment, please refer to Figures 3-5 , Figure 7 , Figure 10 and Figure 14 The second clearance area 2314 is formed in the support mechanism 2316. The second mounting base 341 includes a common base 3411 and a base 3412. The common base 3411 extends along the first direction to the corresponding positions of the multiple support mechanisms 2316. The common base 3411 is disposed on the turntable 22. The common base 3411 is located on the side of the guide mechanism 2315 facing the reference surface 221 along the second direction. The second driving device 35 drives the common base 3411 to move along the second direction. The base 3412 is connected to the common base 3411. The base 3412 is located on the side of the common base 3411 facing away from the reference surface 221 along the second direction. A base 3412 is provided at the corresponding position of each support mechanism 2316. The positioning post device group 342 is connected above the base 3412. The base 3412 can move along the second direction into the underside of the support mechanism 2316.

[0322] Multiple hopper assemblies 231 on each side are arranged along the first direction, and correspondingly, multiple support mechanisms 2316 on each side are arranged along the first direction, and correspondingly, multiple guide mechanisms 2315 on each side are arranged along the first direction.

[0323] Each support mechanism 2316 is provided with a base 3412 at its corresponding position, and correspondingly, multiple bases 3412 on each side are arranged along the first direction.

[0324] The public seat 3411 extends along the first direction to the positions corresponding to the multiple support mechanisms 2316, and the base 3412 at the position corresponding to each support mechanism 2316 is connected to the public seat 3411. The public seat 3411 extending along the first direction to the positions corresponding to the multiple support mechanisms 2316 drives the multiple bases 3412 arranged along the first direction to move together.

[0325] In this embodiment, the common seat 3411 is located on the side of the guide mechanism 2315 facing the reference surface 221 along the second direction. The possibility of interference between the common seat 3411 and the hopper assembly 231 is reduced. Each support mechanism 2316 is provided with a base 3412. When the positioning post device moves within the second clearance area 2314, the base 3412 can move along the second direction to below the support mechanism 2316, thereby minimizing the degree to which the positioning post device group 342 can protrude from the base 3412. This increases the deformation resistance of the positioning post device group 342 and facilitates more accurate positioning of the film 100 along the second direction. The second driving device 35 drives the common seat 3411 to move along the second direction. The common seat 3411, which extends along the first direction to the positions corresponding to the multiple support mechanisms 2316, drives the multiple bases 3412 and the positioning post device group 342 connected to the bases 3412 to move together. The positioning post device group 342 corresponding to the multiple support mechanisms 2316 positions the film 100 on each support mechanism 2316 together along the second direction, thereby improving the positioning efficiency.

[0326] The structure of the second mounting base 341 in this application embodiment is not limited. Exemplarily, the second mounting base 341 may not include the base 3412.

[0327] In one embodiment, please refer to Figure 3 and Figure 10 The guide mechanism 2315 and the support mechanism 2316 are arranged along the first direction, and the length direction of the support mechanism 2316 is arranged along the second direction.

[0328] In this embodiment, the support mechanism 2316 is arranged along the second direction along its length. The guide mechanism 2315, which is arranged along the first direction with the support mechanism 2316, is approximately located on the long side of the support mechanism 2316. The span of the guide mechanism 2315 along the second direction can be set to be relatively large, which is beneficial for the guide mechanism 2315 to guide the support mechanism 2316 more smoothly in the vertical direction. The guide mechanism 2315 and the support mechanism 2316 are arranged along the first direction, so that the guide mechanism 2315 can separate two adjacent support mechanisms 2316 in the first direction, reducing interference between two adjacent support mechanisms 2316 along the first direction.

[0329] The arrangement direction of the guide mechanism 2315 and the support mechanism 2316 in this embodiment can be set according to actual needs and is not limited to the first direction.

[0330] The length direction of the support mechanism 2316 in this embodiment can be arranged according to actual needs and is not limited to the second direction.

[0331] In one embodiment, please refer to Figures 4-7 ,as well as Figure 14 The second mounting base 341 is located above the turntable 22.

[0332] In this embodiment, since the second mounting base 341 moves along the second direction, the possibility of interference between the second mounting base 341 above the turntable 22 and the multiple hopper assemblies 231 arranged along the first direction is low. Because the second mounting base 341 is located above the turntable 22, the turntable 22 does not need to have a structure to avoid the positioning post assembly 342 by removing material, which simplifies the structure of the turntable 22 and increases its strength.

[0333] The second mounting base 341 in this embodiment can be located below the turntable 22.

[0334] In one embodiment, please refer to Figures 4-7 ,as well as Figure 13 and Figure 14 The first mounting base 321 is located below the turntable 22, and the second mounting base 341 is located above the turntable 22.

[0335] In this embodiment, the first mounting base 321 and the second mounting base 341 are located on both sides of the turntable 22 in the vertical direction, which can reduce the possibility of interference between the moving first mounting base 321 and the second mounting base 341.

[0336] In one embodiment, please refer to Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 12 as well as Figure 13 The first positioning assembly 3 has an operating part 36 for manual operation to provide power, and both the first drive device 33 and the second drive device 35 have operating parts 36.

[0337] In this embodiment, both the first drive device 33 and the second drive device 35 have manually operated operating parts 36. Power is supplied to the first drive device 33 and the second drive device 35 by an operator operating the corresponding operating part 36. This manual operation eliminates the need to supply power to the first drive device 33 and the second drive device 35 mounted on the turntable 22, reducing the risk of power supply wires becoming entangled during the rotation of the turntable 22.

[0338] In one embodiment, please refer to Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 12 as well as Figure 13 The operating unit 36 ​​is located on the side of each main compartment 23 that is away from the reference plane 221 along the arrangement direction of the two main compartments 23.

[0339] In this embodiment, the operating part 36 is away from the reference surface 221, that is, the operating part 36 is away from the middle position of the turntable 22 and close to the edge of the turntable 22, which makes it convenient for the operator to manually operate the operating part 36.

[0340] In this embodiment, the location of the operating part 36 is not limited. For example, the operating part 36 may be located on one side of the main compartment 23 along the first direction.

[0341] In one embodiment, please refer to Figure 12 and Figure 13 The reference surface 221 has main compartments 23 on both opposite sides along the second direction. The first drive device 33 includes a rotating shaft 331, a first bevel gear 332, a second bevel gear 333, a lead screw 334, and a connecting device 335. The rotating shaft 331 is axially arranged along the second direction and has a corresponding operating part 36. The first bevel gear 332 is connected to the end of the rotating shaft 331 facing the reference surface 221 so that the first bevel gear 332 rotates with the rotating shaft 331. The second bevel gear 333 meshes with the first bevel gear 332. The lead screw 334 is rotatably connected to the turntable 22, and the second bevel gear 333 is connected to one end of the lead screw 334 so that the second bevel gear 333 rotates with the lead screw 334. The lead screw 334 is axially arranged along the first direction. The connecting device 335 is threadedly connected to the lead screw 334 so that the lead screw 334 drives the connecting device 335 to move along the first direction. The connecting device 335 is mounted on the second positioning assembly 32.

[0342] The central axes of the first bevel gear 332 and the second bevel gear 333, which mesh with each other, intersect each other and are used to transmit motion between non-parallel shafts.

[0343] For example, the central axes of the first bevel gear 332 and the second bevel gear 333 are perpendicular to each other.

[0344] In this embodiment, the central axes of the meshing first bevel gear 332 and second bevel gear 333 intersect each other. The operator can easily drive the rotating shaft 331 to rotate via the operating part 36, which is positioned away from the reference surface 221 along the second direction. The first and second bevel gears 332 and 333 change the direction of the rotation centerline, causing the rotation centerline of the lead screw 334 to be arranged along the first direction, i.e., the axial direction of the lead screw 334 is arranged along the first direction. The rotation of the lead screw 334 drives the connecting device 335 and the second positioning assembly 32 to move along the first direction. Therefore, the operating part 36 can easily drive the rotating shaft to move, thereby moving the second positioning assembly 32 along the first direction to position the film 100.

[0345] In one embodiment, please refer to Figure 13 The rotating shaft 331 includes a shaft body 3311 and a hand crank 3312 connected to each other. The shaft body 3311 is arranged along the second direction. The hand crank 3312 is connected to the end of the rotating shaft 331 away from the reference surface 221. The hand crank 3312 has a corresponding operating part 36.

[0346] The hand crank 3312 in this embodiment facilitates manual operation by the operator.

[0347] In one embodiment, please refer to Figure 9 and Figure 11 The first positioning component 31 includes a fourth positioning post 311 and a fifth positioning post 312. The fourth positioning post 311 is located on one side of the hopper component 231 along the second direction, and the fifth positioning post 312 is located on one side of the hopper component 231 along the first direction.

[0348] For example, both the fourth positioning post and the fifth positioning post 312 are cylindrical in shape.

[0349] In this embodiment, the fourth positioning post 311 and the third positioning component 34 are used for positioning at least along the second direction, and the fifth positioning post 312 and the second positioning component 32 are used for positioning along the first direction, thereby adapting to the positioning of films 100 with different sizes and specifications from different directions.

[0350] In one embodiment, please refer to Figures 16-22The material preparation table 6 has a reference positioning part 61. The second positioning assembly 7 includes a fourth positioning component 71, a third driving device 72, a fifth positioning component 73, and a fourth driving device 74. The fourth positioning component 71 is movably disposed on the material preparation table 6. The third driving device 72 is mounted on the material preparation table 6 and drives the fourth positioning component 71 to move along a third direction. The fourth positioning component 71 and the reference positioning part 61 are used to position the film 100 along the third direction. The fifth positioning component 73 is movably disposed on the material preparation table 6. The fourth driving device 74 is mounted on the material preparation table 6 and drives the fifth positioning component 73 to move along a fourth direction. The fourth direction and the third direction are arranged intersectingly, and both the third direction and the fourth direction are arranged intersectingly with the vertical direction. The fifth positioning component 73 and the reference positioning part 61 are used to position the film 100 along the fourth direction.

[0351] The fourth positioning component 71 and the reference positioning part 61 are used to position the film 100 along the third direction, and the fifth positioning component 73 and the reference positioning part 61 are used to position the film 100 along the fourth direction. The reference positioning part 61 is straddling one side of the material preparation table 6 along the third direction and the other side of the material preparation table 6 along the fourth direction.

[0352] For example, please refer to Figure 17 and Figure 23 The reference positioning part 61 is L-shaped.

[0353] For example, the third driving device 72 includes a second driver 721 and a first transmission mechanism 722 mounted on the material preparation table 6, and a fourth positioning component 71 disposed on the first transmission mechanism 722. The second driver 721 drives the first transmission mechanism 722 to move, thereby causing the fourth positioning component 71 to move in a third direction.

[0354] For example, the second driver 721 may be a motor or a rotary cylinder.

[0355] For example, the first transmission mechanism 722 can be a lead screw pair mechanism.

[0356] A lead screw mechanism is used to convert rotational motion into linear motion.

[0357] Exemplarily, the fourth drive device 74 includes a third drive 741, a second transmission mechanism 742, and a transition member 743. The third drive 741 and the second transmission mechanism 742 are mounted on the preparation table 6, the transition member 743 is mounted on the second transmission mechanism 742, and the fifth positioning component 73 is connected to the transition member 743. The third drive 741 drives the second transmission mechanism 742 to move, thereby moving the transition member 743, and the transition member 743 drives the fifth positioning component 73 to move along the fourth direction.

[0358] For example, the third drive 741 can be a motor or a rotary cylinder.

[0359] For example, the second transmission mechanism 742 can be a lead screw pair mechanism.

[0360] In this embodiment, the fourth positioning component 71 is moved along a third direction by the third driving device 72 to change the distance between the fourth positioning component 71 and the reference positioning part 61 along the third direction, thereby positioning films 100 of different sizes along the third direction. The fifth positioning component 73 is moved along a fourth direction by the fourth driving device 74 to change the distance between the fifth positioning component 73 and the reference positioning part 61 along the fourth direction, thereby positioning films 100 of different sizes along the fourth direction. In two intersecting directions within a plane intersecting the vertical direction, the reference positioning part 61, the fourth positioning component 71, and the fifth positioning component 73 position films 100 of different sizes, ensuring that the films 100 are completely positioned within the plane intersecting the vertical direction. Therefore, the second positioning assembly 7 can effectively position films 100 of different sizes placed on the preparation table 6, achieving compatibility with films 100 of different sizes.

[0361] In one embodiment, please refer to Figure 17 and Figure 18 The material preparation table 6 has multiple material preparation sections 62, which are used to carry the film 100 after removing the release paper 101. The multiple material preparation sections 62 are arranged sequentially along a third direction, and a reference positioning section 61 is provided at the corresponding position of each material preparation section 62.

[0362] In this embodiment, multiple material preparation sections 62 are arranged sequentially along a third direction, and the application assembly 8 can pick up multiple film sheets 100 from the multiple material preparation sections 62 of the material preparation table 6 at one time and apply them to the surface of the object to be applied. A reference positioning section 61 is provided at a corresponding position of each material preparation section 62, and the film sheet 100 on each material preparation section 62 is positioned by the corresponding reference positioning section 61.

[0363] Understandably, the material preparation table 6 holds the film 100 after the release paper 101 has been peeled off by the paper-peeling assembly 5. The material picking assembly 4 places the film 100 with the release paper 101 removed into the material preparation section 62 for positioning. The application assembly 8 can then pick up the positioned film 100 from the material preparation section 62 and apply it to the object to be applied. Therefore, there will not be too many film 100s accumulating on the material preparation table 6, and the height of the film 100s stacked vertically in the material preparation section 62 will not be too high. In fact, the film 100s in the material preparation section 62 will not be stacked vertically at all; each material preparation section 62 holds only one film 100. The film 100s stored on each material preparation table 6 will be relatively short in the vertical direction.

[0364] In one embodiment, please refer to Figure 17 , Figure 18 and Figure 20 The material preparation unit 62 has a third clearance area 621 extending along a third direction. The fourth positioning component 71 includes a third mounting base 711 and a first positioning member 712. The third mounting base 711 is disposed below the material preparation table 6, and the third driving device 72 drives the third mounting base 711 to move along the third direction. The first positioning member 712 is connected above the third mounting base 711 and has a plurality of first positioning protrusions 7121 passing through the material preparation table 6. The plurality of first positioning protrusions 7121 are arranged at intervals along the fourth direction. A first positioning member 712 is provided at a corresponding position in each material preparation unit 62, and the first positioning protrusions 7121 can move within the corresponding third clearance area 621.

[0365] The third clearance zone 621 is the space to avoid the first positioning protrusion 7121. The first positioning protrusion 7121 moves within the third clearance zone 621 to reduce the possibility of interference between the first positioning protrusion 7121 and the material preparation section 62.

[0366] In this embodiment, the third mounting base 711 is located below the material preparation table 6. The third mounting base 711, which moves along the third direction, will not obstruct the film 100 on the material preparation section 62, making it convenient for the laying assembly 8 to pick up the film 100 on the material preparation table 6. The first positioning member 712 is connected above the third mounting base 711. Since the material preparation table 6 does not accumulate too many film 100s, and the film 100s stored on each material preparation table 6 are relatively short in the vertical direction, the first positioning member 712 can be relatively small in the vertical direction, that is, the height of the first positioning member 712 is relatively small, so that the first positioning member 712 has better resistance to deformation. Even if the first positioning member 712 is provided with multiple first positioning protrusions 7121 that abut against and position the film 100, the deformation caused by the reaction force of the film 100 acting on the first positioning protrusions 7121 is small. The slight deformation of the first positioning member 712, together with the multiple first positioning protrusions 7121 arranged at intervals along the fourth direction, pushes the film 100 to move and position along the third direction. This allows the first positioning member 712 to push the film 100 to move relatively smoothly along the third direction, alleviating the tilting of the film 100 during movement. The first positioning protrusions 7121 move within the third clearance area 621 to reduce the possibility of interference between the first positioning protrusions 7121 and the material preparation section 62.

[0367] In one embodiment, please refer to Figure 17 , Figure 18 and Figure 20 The multiple first positioning elements 712 arranged along the third direction are all connected to the third mounting base 711.

[0368] Each material preparation section 62 is provided with a first positioning element 712 at a corresponding position. Multiple material preparation sections 62 are arranged along a third direction, and the corresponding multiple first positioning elements 712 are arranged along a third direction.

[0369] In this embodiment, the third mounting base 711 is driven to move along a third direction by the third driving device 72. The third mounting base 711 drives multiple first positioning members 712 connected to the third mounting base 711 to move together, thereby realizing the positioning of multiple film sheets 100 on the multiple material preparation parts 62 and improving the positioning efficiency.

[0370] In one embodiment, please refer to Figure 17 , Figure 18 and Figure 20 Each material preparation section 62 has multiple third clearance areas 621, which are arranged at intervals along the fourth direction. Each third clearance area 621 has a first positioning protrusion 7121 at its corresponding position.

[0371] In this embodiment of the application, a first positioning protrusion 7121 is provided at the corresponding position of each third clearance area 621. The third clearance area 621 and the first positioning protrusion 7121 correspond one-to-one. The part of the material preparation part 62 between two adjacent third clearance areas 621 can still play the role of supporting the film 100, so that the material preparation part 62 can better support the film 100.

[0372] In one embodiment, please refer to Figure 20 The first positioning protrusion 7121 is square in shape.

[0373] In this embodiment, the square first positioning protrusion 7121 contacts the surface of the film 100 during the process of pushing the film 100 to move, which is beneficial to smoothly push the film 100 to move.

[0374] In one embodiment, please refer to Figure 18 and Figure 22 The material preparation unit 62 has a fourth clearance area 622 extending in a fourth direction. The fifth positioning component 73 includes a fourth mounting base 731 and a second positioning member 732. The fourth mounting base 731 is disposed on the material preparation table 6, and the fourth driving device 74 drives the fourth mounting base 731 to move in the fourth direction. The second positioning member 732 is connected to the fourth mounting base 731 and has a plurality of second positioning protrusions 7321. The plurality of second positioning protrusions 7321 are arranged at intervals in a third direction. A second positioning member 732 is disposed at a corresponding position in each material preparation unit 62, and the second positioning protrusions 7321 are movable within the corresponding fourth clearance area 622.

[0375] The fourth avoidance zone 622 is the space for avoiding the second positioning protrusion 7321.

[0376] In this embodiment, since the film 100 does not accumulate in the preparation section 62, the film 100 stored in the preparation section 62 has a smaller vertical dimension, i.e., a smaller height. Correspondingly, the height of the second positioning member 732 is smaller, and the second positioning member 732 has better resistance to deformation. Even if the second positioning member 732 has multiple second positioning protrusions 7321 spaced apart along the third direction, the reaction force applied by the film 100 to the multiple second positioning protrusions 7321 will not cause the second positioning member 732 to deform significantly. Moreover, the multiple second positioning protrusions 7321 spaced apart along the third direction together push the film 100 to move and position along the fourth direction, so that the second positioning member 732 can push the film 100 to move along the fourth direction relatively smoothly, which can alleviate the possibility of the film 100 tilting during the movement. The fourth drive device 74 drives the fourth mounting base 731 to move, and the fourth mounting base 731 drives the second positioning protrusion 7321 of the second positioning member 732 to move within the fourth clearance area 622, reducing the possibility of interference between the second positioning protrusion 7321 and the material preparation part 62.

[0377] For example, the size of the film that can be compatible between the first positioning protrusion 7121 and the reference positioning part 61 along a third direction is 0~320mm. The size of the film that can be compatible between the second positioning protrusion 7321 and the reference positioning part 61 along a fourth direction is 0~200mm.

[0378] In one embodiment, please refer to Figure 18 and Figure 22 Each material preparation section 62 has multiple fourth clearance areas 622, which are arranged at intervals along a third direction. Each fourth clearance area 622 has a second positioning protrusion 7321 at its corresponding position.

[0379] In this embodiment, multiple fourth clearance areas 622 are arranged at intervals along a third direction. The portion of the material preparation unit 62 between two adjacent fourth clearance areas 622 can still support the film 100 well. The arrangement of the fourth clearance areas 622 can not only meet the needs of mobile positioning, but also enable the material preparation unit 62 to support the film 100 well.

[0380] In one embodiment, please refer to Figure 22 The second positioning protrusion 7321 is square in shape.

[0381] In this embodiment, the square second positioning protrusion 7321 can contact the surface of the film 100, so that the second positioning member 732 can push the film 100 to move relatively smoothly to position the second film 100.

[0382] In one embodiment, please refer to Figure 17 , Figure 18 and Figure 21 The material preparation section 62 and the reference positioning section 61 are both located below the fourth mounting base 731, the fourth clearance area 622 is located above the material preparation section 62, and the bottom of the fourth clearance area 622 is closed.

[0383] The bottom of the fourth clearance zone 622 is closed, and the fourth clearance zone 622 does not penetrate the material preparation platform 6 in the vertical direction.

[0384] In this embodiment, both the material preparation section 62 and the reference positioning section 61 are located below the fourth mounting base 731, which reduces the possibility of interference between the fourth mounting base 731 and the material preparation section 62 and the reference positioning section 61. The fourth clearance area 622 is located above the material preparation section 62, and the bottom of the fourth clearance area 622 is closed. The second positioning protrusion 7321 of the second positioning member 732 connected to the fourth mounting base 731 extends into the fourth clearance area 622 from above. The fourth clearance area 622 does not penetrate the material preparation table 6 in the vertical direction, which helps to increase the strength of the strong material preparation table 6.

[0385] In one embodiment, please refer to Figure 21 The third drive 741 and the second transmission mechanism 742 are located below the material preparation platform 6, and the transition piece 743 passes through the material preparation platform 6 and is connected to the fourth mounting base 731.

[0386] In this embodiment, the third driver 741 drives the transmission mechanism to move, thereby causing the transition member 743 to move along the fourth direction. The transition member 743 causes the fourth mounting base 731 to move along the fourth direction. The third driver 741 and the second transmission mechanism 742 are disposed below the material preparation platform 6, which can reduce the possibility of interference between the third driver 741 and the second transmission mechanism 742 and the material preparation section 62 above the material preparation platform 6.

[0387] In one embodiment, please refer to Figure 22 The multiple second positioning elements 732 arranged along the third direction are all connected to the fourth mounting base 731.

[0388] Each material preparation section 62 is provided with a second positioning element 732 at a corresponding position. Multiple material preparation sections 62 are arranged along a third direction, and the corresponding multiple second positioning elements 732 are arranged along a third direction.

[0389] In this embodiment, the fourth mounting base 731 is driven to move along the fourth direction by the fourth driving device 74. The fourth mounting base 731 drives the multiple second positioning members 732 connected to the fourth mounting base 731 to move together, thereby realizing the positioning of the films 100 on the multiple material preparation parts 62 together and improving the positioning efficiency.

[0390] In one embodiment, please refer to Figures 16-18 ,as well as Figure 21The preparation table 6 includes a workbench 63 and a tray 64. The workbench 63 is connected to the frame 1, and the second positioning assembly 7 is disposed on the workbench 63. The tray 64 is installed above the workbench 63 and is used to carry the film 100 for removing the release paper 101.

[0391] Tray 64 is used to carry film 100.

[0392] For example, the material preparation section 62 is formed on the pallet 64.

[0393] For example, the reference positioning part 61 is formed on the tray 64.

[0394] For example, the third clearance zone 621 extends through the tray 64 and the workbench 63.

[0395] For example, a fourth clearance zone 622 is formed on the pallet 64.

[0396] For example, please refer to Figure 18 Four trays 64 are arranged along a third direction, and each tray 64 has a preparation section 62.

[0397] In this embodiment, the workbench 63 connected to the frame 1 is the main body of the material preparation table 6. The workbench 63 can support the tray 64 above which is used to carry the film 100. The second positioning assembly 7 is set on the workbench 63 that supports the tray 64, so that the second positioning assembly 7 can position the film 100 on the tray 64.

[0398] In one embodiment, please refer to Figure 23 The tray 64 has ribs 641 on top for carrying the film 100 for removing the release paper 101. There are multiple ribs 641, which are arranged at intervals.

[0399] In this embodiment, the spaced ribs 641 can reduce the contact area between the film 100 and the tray 64, reduce the adhesion between the side of the film 100 that removes the release paper 101 and the tray 64, and make it easier for the laying assembly 8 to pick up the film 100 on the tray 64.

[0400] In one embodiment, please refer to Figures 24-26The material handling assembly 4 includes a first transfer component 42 and a material handling device 43. The first transfer component 42 is disposed on the frame 1. The material handling device 43 is disposed on the first transfer component 42, and the first transfer component 42 drives the material handling device 43 to move. The material handling device 43 includes a first airflow distributor 431 and a first suction assembly 432 connected to each other. The first airflow distributor 431 is disposed on the first transfer component 42 and has a first air chamber and a negative pressure interface. There are multiple first air chambers, which are isolated from each other. Each first air chamber is connected to a corresponding negative pressure interface. A pickup part 41 is formed on the first suction assembly 432, and each first air chamber is connected to a corresponding pickup part 41.

[0401] The first transfer component 42, which is mounted on the frame 1, is the main moving structure of the material handling assembly 4.

[0402] The material picking device 43 picks up the film 100 through the picking part 41 of the first suction assembly 432.

[0403] Multiple first air chambers are isolated from each other, and the air pressure in each first air chamber can be adjusted independently. For example, if one first air chamber is drawn into negative pressure through a negative pressure port, the air pressure in the other first air chambers can remain unchanged and unaffected by the negative pressure.

[0404] In this embodiment, the first airflow distributor 431 has multiple mutually isolated first air chambers. A negative pressure interface can draw the corresponding first air chambers into a negative pressure state, allowing the pickup section 41 corresponding to the negative pressure chamber to adsorb the film 100, thus achieving film 100 pickup. Depending on the size of the film 100, the pickup section 41 required to create negative pressure for film 100 adsorption will vary accordingly. Drawing the first air chamber corresponding to the required negative pressure pickup section 41 into a negative pressure state through the negative pressure interface allows for the adsorption of film 100 of the corresponding size. For smaller film 100s, drawing a portion of the first air chambers into a negative pressure state is sufficient to firmly adsorb the film 100, achieving film 100 pickup and contributing to energy saving and consumption reduction.

[0405] In the process of adsorbing the film 100, the material handling device 43 of this application embodiment is not limited to drawing the corresponding first air chamber into negative pressure according to the size of the film 100. For example, all first air chambers can be drawn into negative pressure, and all pickup parts 41 connected to the first air chambers can adsorb the film 100. For the material handling device 43 that draws all first air chambers into negative pressure, film 100 of any size and specification can be adsorbed by the pickup parts 41 of the material handling device 43, thereby realizing the picking up of film 100 by the material handling device 43.

[0406] The first airflow distributor 431 in this application embodiment is not limited to multiple first air chambers isolated from each other. Exemplarily, the multiple first air chambers are interconnected or the number of first air chambers is one, any one of the first air chambers is drawn into negative pressure through a negative pressure interface, and all the first air chambers form negative pressure.

[0407] In one embodiment, please refer to Figure 27 One of the first air chambers is the main air chamber 43111, and the other of the first air chambers is the first extended air chamber 43112. The first extended air chamber 43112 spans the main air chamber 43111 on one side along the fifth direction and the other side along the sixth direction. The fifth and sixth directions are arranged intersectingly, and both the fifth and sixth directions are arranged intersectingly with the arrangement directions of the first airflow distributor 431 and the first suction assembly 432. One of the first air chambers is the second extended air chamber 43113, which is located on one side of the first extended air chamber 43112 along the fifth direction. One of the first air chambers is the third extended air chamber 43114, which is located on one side of the first extended air chamber 43112 along the sixth direction.

[0408] The material handling device 43 adsorbs the film 100. The first airflow distributor 431 and the first suction component 432 are arranged in a roughly cross-shaped manner with the surface of the film 100 that is adsorbed. The film 100 has different size specifications, and the size specifications of the surface of the film 100 that is adsorbed are different.

[0409] In this embodiment, the first extended air chamber 43112 spans the main air chamber 43111 along the fifth direction and the main air chamber 43111 along the sixth direction, respectively. Since the fifth and sixth directions are both intersecting the arrangement directions of the first airflow distributor 431 and the first suction assembly 432, the main air chamber 43111, combined with the first extended air chambers 43112 extending along the fifth and sixth directions, can adsorb films 100 with larger dimensions. The film 100 adsorbed by the picking part 41 of the picking device 43 needs to have its release paper 101 torn off by the paper tearing assembly 5. The picking device 43 should adsorb as close as possible to the edge of the film 100 so that the paper tearing assembly 5 can tear off the release paper 101. Therefore, the dimensions of the first suction assembly 432 of the picking device 43 in the fifth and sixth directions should be made as large as possible. The second expansion chamber 43113 is located on one side of the first expansion chamber 43112 along the fifth direction, and the third expansion chamber 43114 is located on one side of the first expansion chamber 43112 along the sixth direction. Since the second expansion chamber 43113 and the third expansion chamber 43114 are isolated from each other, the depth of the second expansion chamber 43113 and the third expansion chamber 43114 can be appropriately smaller, which is beneficial to improve the adsorption force formed by the negative pressure drawn by the second expansion chamber 43113 and the third expansion chamber 43114, thereby adsorbing the film 100 more firmly.

[0410] For example, please refer to Figure 27 Projecting along the arrangement direction of the first airflow distributor 431 and the first suction assembly 432, the projection area of ​​the first airflow distributor 431 is rectangular. The length direction of the first airflow distributor 431 is arranged along the fifth direction, and the width direction of the first airflow distributor 431 is arranged along the sixth direction. The second expansion chamber 43113 and the third expansion chamber 43114 are isolated from each other. The depth of the second expansion chamber 43113 along the fifth direction and the depth of the third expansion chamber 43114 along the fifth direction can be appropriately small. The second expansion chamber 43113 and the third expansion chamber 43114 can obtain a large negative pressure suction force under the suction of their respective negative pressure suction ports.

[0411] For example, the main air chamber 43111 is evacuated to a negative pressure so that the corresponding pickup unit 41 can pick up the film 100 with a smaller size. The first expansion air chamber 43112, the second expansion air chamber 43113, and the third expansion air chamber 43114 are not evacuated to a negative pressure, and the corresponding air pressures that are not evacuated to a negative pressure are approximately atmospheric pressure. For the film 100 with a larger size, the main air chamber 43111 and the first expansion air chamber 43112 can be evacuated to a negative pressure so that the corresponding pickup unit 41 can pick up the film 100. The second expansion air chamber 43113 and the third expansion air chamber 43114 are not evacuated to a negative pressure, and the corresponding air pressures that are not evacuated to a negative pressure are approximately atmospheric pressure. When the main air chamber 43111, the first extended air chamber 43112, and the second extended air chamber 43113 are drawn into negative pressure, the size of the film 100 that the first suction assembly 432 can adsorb along the fifth direction reaches its maximum, while the third extended air chamber 43114 is not drawn into negative pressure. When the main air chamber 43111, the first extended air chamber 43112, and the third extended air chamber 43114 are drawn into negative pressure, the size of the film 100 that the first suction assembly 432 can adsorb along the sixth direction reaches its maximum, while the second extended air chamber 43113 is not drawn into negative pressure. When the main air chamber 43111, the first extended air chamber 43112, the second extended air chamber 43113, and the third extended air chamber 43114 are all drawn into negative pressure, the size of the film 100 that the first suction assembly 432 can adsorb reaches its maximum.

[0412] For example, whether the first air chamber is drawn into negative pressure or not drawn into negative pressure, it corresponds to adsorbing films 100 within a certain size range, rather than adsorbing films 100 of a specific size.

[0413] For example, when the main air chamber 43111 is drawn into negative pressure, the first expansion air chamber 43112, the second expansion air chamber 43113, and the third expansion air chamber 43114 are not drawn into negative pressure, thus adsorbing films 100 within a certain size range, rather than adsorbing films 100 of a specific size. When the main air chamber 43111 and the first expansion air chamber 43112 are drawn into negative pressure, the second expansion air chamber 43113 and the third expansion air chamber 43114 are not drawn into negative pressure, thus adsorbing films 100 within a certain size range, rather than adsorbing films 100 of a specific size.

[0414] It is understood that the expansion method of the first air chamber is not limited to the above-described method. For example, the second expansion air chamber and the third expansion air chamber 43114 can be interconnected, the main air chamber 43111 and the first expansion air chamber 43112 are isolated from each other, the main air chamber 43111 is isolated from the second expansion air chamber 43113 and the third expansion air chamber 43114, and the first expansion air chamber 43112, the second expansion air chamber 43113 and the third expansion air chamber 43114 are isolated from each other.

[0415] In one embodiment, please refer to Figures 24-26 The first transfer component 42 includes a first transfer body 421 and a first mounting bracket 422 disposed on the first transfer body 421. The first transfer body 421 drives the first mounting bracket 422 to move. The first mounting bracket 422 is connected to the side of the first airflow distributor 431 away from the first suction assembly 432. The negative pressure interface is located on the outer side of the first airflow distributor 431. The arrangement direction of the first airflow distributor 431 and the first suction assembly 432 is arranged crosswise with the orientation of the negative pressure interface.

[0416] In this embodiment, the negative pressure interface is located on the outer side of the first airflow distributor 431. The arrangement direction of the first airflow distributor 431 and the first suction assembly 432 is arranged in a cross direction with the orientation of the negative pressure interface. The orientation of the negative pressure interface can avoid the first mounting bracket 422 as much as possible, reducing the possibility of interference between the pipe connecting the negative pressure interface to the external negative pressure source and the first mounting bracket 422.

[0417] In one embodiment, please refer to Figure 27 The negative pressure interface connected to the main air chamber 43111 is the first negative pressure interface 43121. The main air chamber 43111 has a first negative pressure interface 43121 on one side along the fifth direction and on one side along the sixth direction. The negative pressure interface connected to the first extended air chamber 43112 is the second negative pressure interface 43122. The first extended air chamber 43112 has a second negative pressure interface 43122 on the side along the fifth direction facing the corresponding first negative pressure interface 43121. The first extended air chamber 43112 has a second negative pressure interface 43122 on the side along the sixth direction facing the corresponding first negative pressure interface 43121. A second negative pressure port 43122 is provided on one side of the pressure port 43121. The negative pressure port connected to the second expansion chamber 43113 is the third negative pressure port 43123. The second expansion chamber 43113 is provided with the third negative pressure port 43123 on the side away from the first expansion chamber 43112 along the fifth direction. The negative pressure port connected to the third expansion chamber 43114 is the fourth negative pressure port 43124. The third expansion chamber 43114 is provided with the fourth negative pressure port 43124 on the side away from the first expansion chamber 43112 along the sixth direction.

[0418] In this embodiment, the negative pressure interface is located on the outer side of the first airflow distributor 431, and the arrangement direction of the first airflow distributor 431 and the first suction assembly 432 is intersected with the orientation of the negative pressure interface. A first negative pressure interface 43121 is provided on both one side of the main air chamber 43111 along the fifth direction and the other side of the main air chamber 43111 along the sixth direction, allowing suction from different sides of the main air chamber 43111, which helps to improve the negative pressure suction force at various locations within the main air chamber 43111. Since the first extended air chamber 43112 spans the main air chamber 43111 along the fifth direction and the main air chamber 43111 along the sixth direction, and the depths of the first extended air chamber 43112 along the fifth and sixth directions are not very deep, the arrangement of the second negative pressure port 43122 allows for suction of the first extended air chamber 43112 from different directions, which helps to improve the negative pressure suction force at various locations within the main air chamber 43111. On the other hand, it facilitates the arrangement of the second extended air chamber 43113 and the third negative pressure port 43123 on the side of the first extended air chamber 43112 along the fifth direction away from the main air chamber 43111, and also facilitates the arrangement of the third extended air chamber 43114 and the fourth negative pressure port 43124 on the side of the first extended air chamber 43112 along the sixth direction. The second expansion chamber 43113 has a third negative pressure port 43123 on the side opposite to the first expansion chamber 43112 along the fifth direction, which makes the depth of the second expansion chamber 43113 along the fifth direction smaller, which is beneficial to improving the negative pressure suction of the second expansion chamber 43113. The third expansion chamber 43114 has a fourth negative pressure port 43124 on the side opposite to the first expansion chamber 43112 along the sixth direction, which makes the depth of the third expansion chamber 43114 along the sixth direction smaller, which is beneficial to improving the negative pressure suction of the third expansion chamber 43114.

[0419] In one embodiment, please refer to Figures 26-28 The first suction assembly 432 includes a first suction nozzle 4321 and a first protective block 4322. The first suction nozzle 4321 is mounted on the first airflow distributor 431, and each first air chamber communicates with the corresponding first suction nozzle 4321. A pickup part 41 is formed on the first suction nozzle 4321. The first protective block 4322 is connected to the side of the first airflow distributor 431 facing the first suction nozzle 4321. The first protective block 4322 has a clearance hole 43221 that penetrates through the first protective block 4322. The first suction nozzle 4321 passes through the clearance hole 43221 and partially protrudes from the side of the first protective block 4322 away from the first airflow distributor 431.

[0420] In this embodiment, the first suction nozzle 4321 is installed on the first airflow distributor 431. When the first air chamber is drawn into a negative pressure, the first suction nozzle 4321 can adsorb the film 100 through the pickup part 41. The first protective block 4322 is connected to the side of the first airflow distributor 431 facing the first suction nozzle 4321. The clearance hole 43221 passes through the first protective block 4322. The first suction nozzle 4321 partially protrudes from the side of the first protective block 4322 away from the first airflow distributor 431. The first suction nozzle 4321, which passes through the clearance hole 43221, can pass through the first protective block 4322, which facilitates the adsorption of the film 100 by the first suction nozzle 4321. External lateral impacts in the direction intersecting the vertical direction will be blocked by the first protective block 4322. The first protective block 4322 blocks the lateral external impacts and protects the first suction nozzle 4321 in the avoidance hole 43221, reducing the impact of lateral external impacts on the first suction nozzle 4321 and making it easier for the first suction nozzle 4321 to adsorb the film 100 more stably.

[0421] In one embodiment, please refer to Figure 28 The clearance hole 43221 is an elongated hole, and there are multiple clearance holes 43221. The multiple clearance holes 43221 are arranged at intervals, and the multiple first suction nozzles 4321 in each clearance hole 43221 are arranged sequentially along the length direction of the clearance hole 43221.

[0422] For example, a plurality of first suction nozzles 4321 in each clearance hole 43221 are arranged sequentially along the length direction of the clearance hole 43221. Each first suction nozzle 4321 in each clearance hole 43221 can communicate with the same first air chamber or with different first air chambers.

[0423] In this embodiment, multiple first suction nozzles 4321 within each clearance hole 43221 are arranged sequentially along the length of the clearance hole 43221. The width dimension of the clearance hole 43221 can be set to be relatively small, which is beneficial for arranging a larger number of clearance holes 43221 at intervals. The portion of the first protective block 4322 between two clearance holes 43221 can be connected to the first airflow distributor 431 via a connector 534. The connector 534, used to connect the first protective block 4322 and the first airflow distributor 431, can be flexibly arranged between the corresponding two clearance holes 43221 according to actual needs, which is beneficial for a more secure connection between the first protective block 4322 and the first airflow distributor 431.

[0424] In one embodiment, please refer to Figure 29 and Figure 30The laying assembly 8 includes a second transfer component 81 and a laying device 82. The second transfer component 81 is disposed on the frame 1. The laying device 82 is disposed on the second transfer component 81. The second transfer component 81 drives the laying device 82 to move to pick up the film 100 on the material preparation table 6 for laying. The laying device 82 includes a second airflow distributor 821 and a second suction assembly 822 connected to each other. The second airflow distributor 821 is disposed on the second transfer component 81 and has a second air chamber and a suction port. There are multiple second air chambers, which are isolated from each other. Each second air chamber is connected to a corresponding suction port. The second suction assembly 822 has an adsorption part 8221 for adsorbing the film 100. Each second air chamber is connected to a corresponding adsorption part 8221.

[0425] The first transfer component 42, mounted on the frame 1, is the main moving structure of the material handling assembly 4. The second transfer component 81 drives the second airflow distributor 821 to move, thereby moving the second suction assembly 822.

[0426] In this embodiment, multiple second air chambers are isolated from each other, and each air chamber is connected to a corresponding adsorption part 8221. Any one of the second air chambers is drawn into a negative pressure via a suction port, enabling the corresponding adsorption part 8221 to create a negative pressure to adsorb the film 100. Depending on the size of the film 100, the corresponding second air chamber is drawn into a negative pressure so that the adsorption part 8221 connected to the corresponding second air chamber can adsorb the film 100. The remaining second air chambers are not drawn into a negative pressure. For smaller films 100, drawing a portion of the second air chambers into a negative pressure is sufficient to adsorb the film 100, which helps reduce energy loss.

[0427] In one embodiment, please refer to Figure 29 and Figure 30 The second transfer component 81 includes a second transfer body 811 and a second mounting bracket 812 disposed on the second transfer body 811. The second transfer body 811 drives the second mounting bracket 812 to move. The second mounting bracket 812 is connected to the side of the second airflow distributor 821 away from the second suction assembly 822. The suction port is located on the outer side of the second airflow distributor 821. The arrangement direction of the second airflow distributor 821 and the second suction assembly 822 is arranged crosswise with the orientation of the suction port.

[0428] In this embodiment, the second transfer body 811 drives the second mounting bracket 812 to move, and the second mounting bracket 812 drives the second airflow distributor 821 to move. The suction port is located on the outer side of the second airflow distributor 821. The arrangement direction of the second airflow distributor 821 and the second suction assembly 822 is intersected with the orientation of the suction port. The orientation of the suction port is not in the same direction as the second mounting bracket 812, which can reduce the possibility of interference between the pipe connected to the negative pressure source and the second mounting bracket 812.

[0429] Understandably, the application device 82 adsorbs the film 100 from the preparation table 6 to adhere it to the surface of the object to be applied. The film 100 adsorbed by the application device 82 is transferred to the surface of the object to be applied. The film 100 adsorbed by the application device 82 does not need to withstand the tearing force similar to that exerted when the tearing assembly 5 tears off the release paper 101. The adsorption force of the application device 82 on the film 100 can be appropriately reduced, and it is not necessary to adsorb it to the edge of the film 100 as much as possible. Therefore, the second airflow distributor 821 and the second suction assembly 822 of the application device 82 can be appropriately made smaller relative to the film 100. For example, the length of the second airflow distributor 821 can be 0~230mm, and the width of the second airflow distributor 821 can be 0~130mm.

[0430] In one embodiment, please refer to Figure 31 One of the second air chambers is an edge air chamber 8211, which includes a first sub-chamber 82111 and a second sub-chamber 82112 that are interconnected. The first sub-chamber 82111 extends along a seventh direction, and the second sub-chamber 82112 extends along an eighth direction. The seventh and eighth directions are arranged intersectingly, and both the seventh and eighth directions are arranged intersectingly with the arrangement directions of the second airflow distributor 821 and the second suction assembly 822. The suction port communicating with the first sub-chamber 82111 is a first suction port 82121, which is located along the first sub-chamber 82111. The seventh direction is away from the end of the second sub-chamber 82112, and the exhaust port connected to the second sub-chamber 82112 is the second exhaust port 82122. The second exhaust port 82122 is located at the end of the second sub-chamber 82112 away from the first sub-chamber 82111 along the eighth direction. Among all the second air chambers, the other second air chambers except the edge air chamber 8211 are auxiliary air chambers 8213. The auxiliary air chamber 8213 is located on the side of the first sub-chamber 82111 facing the second exhaust port 82122, and the auxiliary air chamber 8213 is located on the side of the second sub-chamber 82112 facing the first exhaust port 82121.

[0431] The seventh and eighth directions are arranged in an intersecting manner, and both the seventh and eighth directions are arranged in an intersecting manner with the arrangement direction of the second airflow distributor 821 and the second suction assembly 822. The second suction assembly 822 adsorbs the film 100 approximately along the arrangement direction of the second airflow distributor 821 and the second suction assembly 822. The second suction assembly 822 can adapt to films 100 with different dimensions along the seventh direction and / or different dimensions along the eighth direction.

[0432] In this embodiment, the suction port is located on the outer side of the second airflow distributor 821. The arrangement direction of the second airflow distributor 821 and the second suction assembly 822 is intersected with the orientation of the suction port. Since the first sub-chamber 82111 and the second sub-chamber 82112 are intersected, the auxiliary air chamber 8213 is located on the side of the first sub-chamber 82111 facing the second suction port 82122, and the auxiliary air chamber 8213 is located on the side of the second sub-chamber 82112 facing the first suction port 82121. The suction ports corresponding to the auxiliary air chamber 8213 are all located on the side of the edge air chamber 8211 facing the auxiliary air chamber 8213. No suction ports are provided on the side of the edge air chamber 8211 away from the auxiliary air chamber 8213. This simplifies the structure of the second airflow distributor 821 and reduces the processing difficulty of the second airflow distributor 821. Since the suction force required for the second suction component 822 to adsorb the film 100 is relatively small, the second airflow distributor 821 and the second suction component 822 of the application device 82 can be appropriately made smaller relative to the film 100. The depth of the first sub-chamber 82111 along the seventh direction and the depth of the second sub-chamber 82112 along the eighth direction are relatively small. The negative pressure suction force at the end of the first sub-chamber 82111 along the seventh direction away from the first air extraction port 82121 can still basically meet the suction force requirements for adsorbing the film 100. The negative pressure suction force at the end of the second sub-chamber 82112 along the eighth direction away from the second air extraction port 82122 can still basically meet the suction force requirements for adsorbing the film 100.

[0433] For example, please refer to Figure 31 The auxiliary gas chamber 8213 has a third air extraction port 82123, which is connected to the auxiliary gas chamber 8213. The third air extraction port 82123 is located on the side of the edge gas chamber 8211 facing the auxiliary gas chamber 8213.

[0434] For example, please refer to Figure 31 For smaller films 100, the edge air chambers 8211 can be drawn into negative pressure, or the edge air chambers 8211 and part of the auxiliary air chambers 8213 can be drawn into negative pressure to adsorb the film 100, while the remaining second air chamber is not drawn into negative pressure. For larger films 100, the edge air chambers 8211 and all auxiliary air chambers 8213 can be drawn into negative pressure to adsorb the film 100.

[0435] For example, whether the second air chamber is drawn into negative pressure or not drawn into negative pressure, it corresponds to adsorbing films 100 within a certain size range, rather than adsorbing films 100 of a specific size.

[0436] For example, please refer to Figure 30 The second suction assembly 822 includes a second suction nozzle 8222 and a second protective block 8223. The second suction nozzle 8222 and the second protective block 8223 are respectively connected to the second airflow distributor 821. The second suction nozzle 8222 communicates with the corresponding second air chamber. The adsorption part 8221 is formed in the second suction nozzle 8222. The second suction nozzle 8222 passes through the second protective block 8223 and protrudes from the side of the second protective block 8223 away from the second airflow distributor 821.

[0437] For example, the length of the second protective block 8223 can be 0~230mm, and the width of the second protective block 8223 can be 0~130mm.

[0438] In one embodiment, please refer to Figure 32 The paper-tearing assembly 5 includes a mounting shaft 52, an adjusting seat 53, and a clamping mechanism 54. A paper-tearing drive device 51 is mounted on the frame 1. The mounting shaft 52 is mounted on the paper-tearing drive device 51, and the paper-tearing drive device 51 drives the mounting shaft 52 to move. The adjusting seat 53 has a locked state and an unlocked state. In the locked state, the adjusting seat 53 moves with the mounting shaft 52; in the unlocked state, the adjusting seat 53 can move axially relative to the mounting shaft 52. The clamping mechanism 54 is mounted on the adjusting seat 53 to move with the adjusting seat 53. The clamping mechanism 54 is used to clamp the release paper 101 of the film 100. Multiple clamping mechanisms 54 are arranged at intervals along the axial direction of the mounting shaft 52.

[0439] In this embodiment, the tearing drive device 51 drives the mounting shaft 52 to move, which in turn moves the adjusting seat 53 and the clamping mechanism 54. The clamping mechanism 54, which clamps the release paper 101, causes the release paper 101 of the film 100 to be torn off from the film body 102. The adjusting seat 53 switches between a locked state and an unlocked state. When the size of the film 100 changes, the adjusting seat 53 is switched from the locked state to the unlocked state. The position of the adjusting seat 53 is adjusted along the axial direction of the mounting shaft 52 to accommodate films 100 of different sizes. After the adjusting seat 53 is adjusted to the corresponding position, the adjusting seat 53 switches from the unlocked state to the locked state, so that the mounting shaft 52 can drive the adjusting seat 53, which is in the locked state, to move.

[0440] In one embodiment, please refer to Figure 33 and Figure 34The adjusting seat 53 includes a seat body 531, a locking block 532, and a connecting member 534. A clamping mechanism 54 is mounted on the seat body 531. The locking block 532 is connected to the side of the seat body 531 opposite to the clamping mechanism 54. The locking block 532 has a mounting cavity 535 and an adjusting gap 533 communicating with the mounting cavity 535. The connecting member 534 passes through the adjusting gap 533 and is connected to the locking block 532. The connecting member 534 is used to change the adjusting gap 533. A mounting shaft 52 passes through the mounting cavity 535.

[0441] In this embodiment, the mounting shaft 52 passes through the mounting cavity 535. By increasing the adjustment gap 533 communicating with the mounting cavity 535 through the connector 534 connected to the locking block 532, the space of the mounting cavity 535 increases accordingly. The locking block 532 releases the mounting shaft 52, and the adjusting seat 53 is in the unlocked state. Conversely, by decreasing the adjustment gap 533 communicating with the mounting cavity 535 through the connector 534 connected to the locking block 532, the space of the mounting cavity 535 decreases accordingly. The locking block clamps the mounting shaft 52, and the adjusting seat 53 is in the locked state.

[0442] For example, the connector 534 can be a screw. Tightening the locking block with the screw reduces the adjustment gap 533, and loosening the screw to expose the locking block increases the adjustment gap 533.

[0443] Exemplary, the embodiments of this application are not limited to adjusting the position of the adjusting seat 53 to accommodate films 100 of different sizes. Exemplary, the clamping part of the clamping mechanism 54 extends axially along the mounting shaft 52. By clamping the release paper 101 of multiple films 100 together with the clamping part extending axially along the mounting shaft 52, it can accommodate the clamping of films 100 of various sizes without requiring adaptive adjustments to the paper tearing assembly 5 for films 100 of different sizes.

[0444] This application provides an adhesive application method. Please refer to [link / reference]. Figure 35 ,include:

[0445] Step S1: Drive the first positioning assembly to move in order to adjust the size of the area on the hopper assembly used for storing film;

[0446] Step S2: Load the corresponding film into the hopper assembly;

[0447] Step S3: Pick up the film placed in the hopper assembly through the picking section of the picking assembly;

[0448] Step S4: Move the picked-up film to the paper tearing assembly via the picking section of the picking assembly;

[0449] Step S5: Drive the paper tearing assembly to peel off the release paper from the film;

[0450] Step S6: The film with the release paper peeled off is moved to the preparation table by the picking part of the picking assembly;

[0451] Step S7: Drive the second positioning assembly to move in order to position the film on the preparation table;

[0452] Step S8: Drive the tiling assembly to pick up the film that has been positioned on the material preparation table;

[0453] Step S9: Move the film picked up by the tiling assembly to the adhesive surface of the object to be tiled.

[0454] For example, the object to be attached can be a single battery cell.

[0455] For example, the movement of the first positioning assembly 3 can be driven manually, pneumatically, or electrically.

[0456] For example, the film 100 can be placed in the hopper assembly 2 first, and then the size of the area on the hopper assembly 2 used to store the film 100 can be adjusted by the first positioning assembly 3 to position the film 100 on the hopper assembly 2.

[0457] For example, the first positioning assembly 3 can be driven to move first to adjust the size of the area on the hopper assembly 2 for storing the film 100, and then the film 100 can be stored in the area for storing the film 100 that has been adjusted by the first positioning assembly 3.

[0458] For example, during the process of the paper tearing assembly 5 peeling off the release paper 101, the film 100 is in a state of being picked up by the material picking assembly 4.

[0459] For example, the operator manually feeds the adhesive sheet 100 through the hopper assembly 2 of the adhesive applicator.

[0460] For example, an automatic film feeding method 100 can be used as needed.

[0461] For example, the material picking assembly 4 picks up four films 100 at a time.

[0462] For example, the tiling assembly 8 picks up two pieces of film 100 each time.

[0463] In this embodiment, the positioning of films 100 of different sizes on the hopper assembly 2 is achieved by adjusting the movement of the first positioning assembly 3. The picking assembly 4 moves the films 100 on the hopper assembly 2 to the paper-tearing assembly 5. The paper-tearing assembly 5 tears off the release paper 101 of the films 100. The films 100 with the release paper 101 torn off are transferred to the preparation platform 6 by the picking assembly 4. The positioning of films 100 of different sizes on the preparation platform 6 is achieved by adjusting the movement of the second positioning assembly 7. The laying assembly 8 pastes the positioned films 100 on the preparation platform 6 onto the surface of the object to be pasted. The first positioning assembly 3 positions the film 100 of different sizes on the hopper assembly 2, and the second positioning assembly 7 positions the film 100 of different sizes on the preparation table 6, so that the adhesive applicator can complete the process of feeding the film 100 of different sizes to the object to be applied, thereby achieving the purpose of being compatible with film 100 of different sizes.

[0464] In one embodiment, please refer to Figure 36 The first positioning assembly 3 includes a first positioning component 31, a second positioning component 32, a first driving device 33, a third positioning component 34, and a second driving device 35, driving the first positioning assembly 3 to move in order to adjust the size of the area on the hopper assembly 2 used for storing the film 100, including:

[0465] Step S11: Drive the second positioning component to move along the first direction by the first driving device to adjust the size of the area on the hopper assembly used for storing film along the first direction;

[0466] Step S12: Drive the third positioning component to move along the second direction via the second driving device to adjust the size of the area on the hopper assembly used for storing film along the second direction.

[0467] The dimension of the area on the hopper assembly 2 used for storing film 100 along the first direction is the distance between the second positioning component 32 and the first positioning component 31 along the first direction.

[0468] For example, please refer to Figure 3 , Figure 9 and Figure 11 The distance between the second positioning component 32 and the first positioning component 31 along the first direction is the distance between the first positioning post 322 and the fifth positioning post 312 along the first direction.

[0469] The dimension of the area on the hopper assembly 2 used for storing film 100 along the second direction is the distance between the third positioning component 34 and the first positioning component 31 along the second direction.

[0470] For example, please refer to Figure 3 , Figure 9 and Figure 11 The distance between the third positioning component 34 and the first positioning component 31 along the second direction is: the distance between the second positioning post 3421 and the fourth positioning post 311 along the second direction.

[0471] In this embodiment, by driving the second positioning component 32 to move along the first direction, the distance between the second positioning component 32 and the first positioning component 31 along the first direction is adjusted, thereby increasing or decreasing the distance between the second positioning component 32 and the first positioning component 31 along the first direction. Correspondingly, the size of the area for storing the film 100 along the first direction is increased or decreased to accommodate the positioning of films 100 with different sizes along the first direction. Similarly, by driving the third positioning component 34 to move along the second direction, the distance between the third positioning component 34 and the first positioning component 31 along the second direction is adjusted, thereby increasing or decreasing the distance between the third positioning component 34 and the first positioning component 31 along the second direction. Correspondingly, the size of the area for storing the film 100 along the second direction is increased or decreased to accommodate the positioning of films 100 with different sizes along the second direction. The second positioning component 32 and the third positioning component 34 move from two different directions, and within a plane intersecting the vertical direction, overall positioning of films 100 of different sizes and specifications on the hopper assembly 2 can be achieved.

[0472] In one embodiment, please refer to Figure 36 The second positioning assembly 7 includes a fourth positioning component 71, a third driving device 72, a fifth positioning component 73, and a fourth driving device 74, driving the second positioning assembly 7 to move in order to position the film 100 on the preparation table 6, including:

[0473] Step S71: Drive the fourth positioning component to move along the third direction through the third driving device to adjust the distance between the fourth positioning component and the reference positioning part along the third direction;

[0474] Step S72: Drive the fifth positioning component to move along the fourth direction using the fourth driving device to adjust the distance between the fifth positioning component and the reference positioning part along the fourth direction.

[0475] For example, please refer to Figure 17 and Figure 18 The distance between the fourth positioning component 71 and the reference positioning part 61 along the third direction is: the distance between the first positioning protrusion 7121 and the reference positioning part 61 along the third direction.

[0476] For example, please refer to Figure 17 and Figure 18 The distance between the fifth positioning component 73 and the reference positioning part 61 along the fourth direction is the distance between the second positioning protrusion 7321 and the reference positioning part 61 along the fourth direction.

[0477] In this embodiment, by driving the fourth positioning component 71 to move along a third direction, the distance between the fourth positioning component 71 and the reference positioning part 61 along the third direction is adjusted, thereby increasing or decreasing the distance between the fourth positioning component 71 and the reference part along the third direction, thus positioning the films 100 of different sizes along the third direction on the preparation table 6. By driving the fifth positioning component 73 to move along a fourth direction, the distance between the fifth positioning component 73 and the reference positioning part 61 along the fourth direction is adjusted, thereby increasing or decreasing the distance between the fifth positioning component 73 and the reference positioning part 61 along the fourth direction, thus positioning the films 100 of different sizes along the fourth direction on the preparation table 6. The fourth positioning component 71 and the fifth positioning component 73 move from two different directions, and in a plane intersecting the vertical direction, overall positioning of films 100 of different sizes and specifications on the preparation table 6 can be achieved.

[0478] In one embodiment, please refer to Figure 36 The film 100 placed in the hopper assembly 2 is picked up by the picking unit 41 of the picking assembly 4, including:

[0479] Step S31: The corresponding first air chamber is drawn into negative pressure through the corresponding negative pressure interface to pick up the film placed in the hopper assembly.

[0480] In this embodiment, which first air chambers are drawn into negative pressure is determined according to the size of the corresponding film 100. For smaller films 100, fewer first air chambers can be drawn into negative pressure according to the actual situation, which can achieve the purpose of adsorbing the film 100 and reduce the energy consumption of negative pressure suction to a certain extent.

[0481] It is understood that the embodiments of this application are not limited to drawing the corresponding first air chamber into negative pressure according to the size of the corresponding film 100. Exemplarily, all first air chambers are drawn into negative pressure, and no adaptive adjustment is required to the material collection assembly 4, which means that it can adsorb a variety of films 100 of different sizes and specifications.

[0482] In one embodiment, please refer to Figure 36 The drive assembly 8 picks up the film 100 that has been positioned on the material preparation table 6, including:

[0483] Step S81: The corresponding second air chamber is drawn into negative pressure through the corresponding air extraction port to pick up the film that has been positioned on the material preparation table.

[0484] In this embodiment, which second air chambers are drawn into negative pressure is determined according to the size of the corresponding film 100. For smaller films 100, fewer second air chambers can be drawn into negative pressure according to the actual situation, thus achieving the purpose of adsorbing the film 100 and reducing the energy consumption of negative pressure suction to a certain extent.

[0485] It is understood that the embodiments of this application are not limited to drawing the corresponding second air chamber into negative pressure according to the size of the corresponding film 100. Exemplarily, all second air chambers are drawn into negative pressure, and no adaptive adjustment is required to the laying assembly 8, which means that it can adsorb a variety of films 100 of different sizes and specifications.

[0486] In one embodiment, please refer to Figure 36 The hopper assembly 2 includes a first driver 21, a turntable 22, and a main hopper 23. The first driver 21 drives the turntable 22 to rotate. The plane coinciding with the rotation center line of the turntable 22 is a reference surface 221. On opposite sides of the reference surface 221 corresponding to the turntable 22, one side is a feeding side for feeding the film, and the other side is a picking side for picking up the film. The adhesive application method further includes:

[0487] Step S10: When any hopper component on the material picking side is empty, the turntable is driven to rotate by the first driver to exchange the positions of the two main hoppers.

[0488] The hopper assembly 231 is empty, meaning that the film 100 on the hopper assembly 231 has been completely removed, and there is no film 100 on the hopper assembly 231.

[0489] In this embodiment, if any hopper assembly 231 on the picking side is empty, the picking assembly 4 cannot pick up the film 100 from the corresponding hopper assembly 231. In this case, the turntable 22 is driven to rotate, and the hopper assembly 231 on the feeding side that has completed feeding the film 100 rotates to the picking side so that the picking assembly 4 can pick up the film 100. The empty hopper assembly 231 rotates to the feeding side to feed the film 100. The feeding of the film 100 and the picking up of the film 100 by the picking assembly 4 do not affect each other, thus improving work efficiency.

[0490] Please see Figure 37 The following examples illustrate the adhesive application method.

[0491] Step S101: Load the film into the hopper assembly;

[0492] Step S102: Adjust the position of the adjusting seat along the axial direction of the mounting shaft;

[0493] Step S103: Drive the second positioning component to move along the first direction by the first driving device to adjust the size of the area on the hopper assembly used for storing film along the first direction;

[0494] Step S104: Drive the third positioning component to move along the second direction via the second driving device to adjust the size of the area on the hopper assembly used for storing film along the second direction;

[0495] Step S105: Determine whether there are any empty hopper components among all hopper components on the material picking side;

[0496] If yes, proceed to step S106; otherwise, proceed to step S107.

[0497] Step S106: Drive the turntable to rotate via the first driver to rotate the hopper assembly that has completed film loading and positioning on the loading side to the unloading side;

[0498] Step S107: Move the pickup section of the material pickup assembly above the film on the pickup side;

[0499] Step S108: The corresponding first air chamber is drawn into negative pressure through the corresponding negative pressure interface so that the corresponding pickup part adsorbs the film;

[0500] Step S109: Move the film adsorbed by the material taking assembly to the paper tearing assembly;

[0501] Step S110: Drive the clamping mechanism to clamp the ear of the release paper of the film;

[0502] Step S111: Drive the mounting shaft to rotate by the paper tearing drive device to tear off the release paper of the film held by the clamping mechanism;

[0503] Step S112: Move the film with the release paper removed to the preparation table via the material handling assembly;

[0504] Step S113: Drive the fourth positioning component to move along the third direction by the third driving device to adjust the distance between the fourth positioning component and the reference positioning part along the third direction;

[0505] Step S114: Drive the fifth positioning component to move along the fourth direction by the fourth driving device to adjust the distance between the fifth positioning component and the reference positioning part along the fourth direction;

[0506] Step S115: Move the adsorption part of the drive paving assembly above the film on the preparation table;

[0507] Step S116: The corresponding second air chamber is drawn into negative pressure through the corresponding air extraction port to adsorb the film on the material preparation table.

[0508] Step S117: Move the adhesive film adsorbed by the adsorption part of the mounting assembly to the adhesive surface of the object to be covered.
