Description

Technical Field

[0001] This invention relates to the field of automated production technology, and more specifically to a mounting device. Background Technology

[0002] Existing mounting devices typically operate as follows: the backing paper is adsorbed onto the adsorption element; then, the adsorption element is moved vertically to allow the backing paper to enter the box and adhere to the inner wall of the box; finally, the adsorption element is moved vertically to separate the adsorption element from the backing paper, thus completing the mounting process.

[0003] However, existing packaging devices have the following drawbacks: because the side of the liner paper has adhesive backing, when the absorbent insert enters the box, it easily adheres to the inner wall of the box, resulting in inadequate adhesion or wrinkles in the liner paper; at the same time, when the absorbent insert separates from the liner paper, it is also easy for the liner paper to fall off or be damaged. These defects not only affect the packaging effect and quality of the product, but also increase production costs and time. Summary of the Invention

[0004] Therefore, the present invention aims to provide an mounting device that can reduce the occurrence of incomplete bonding and detachment / damage of the backing paper.

[0005] To solve the above-mentioned technical problems, the present invention provides a mounting device for mounting backing paper onto a box body. The box body has an opening on its upper side, and the backing paper has a bottom surface and a first side surface. The first side surface is provided with adhesive backing. The mounting device includes: Mounting base; An adsorption element is movably disposed vertically relative to the mounting base. The surface of the adsorption element is provided with suction nozzles. The adsorption element has a base plate and a first side plate. The suction nozzles are at least distributed on the first side plate. The base plate is used to adhere to the bottom surface, and the first side plate is used to adhere to the first side surface. The first side plate is inclined upwards from the base plate towards the inside of the adsorption element. An up-down driving mechanism is provided on the mounting base and is drivenly connected to the adsorption element. The up-down driving mechanism is used to drive the adsorption element to move in the up-down direction so that the adsorption element has a first working position located inside the box and a second working position located above the box.

[0006] In one embodiment, the backing paper further has a second side disposed laterally opposite to the first side, and the second side is partially provided with adhesive backing; The adsorption component also has a second side plate that is laterally opposite to the first side plate. The second side plate has suction nozzles distributed on it. The second side plate is used to attach to the second side surface. An inner support block protrudes from the outer side of the second side plate. The inner support block is used to be staggered from the adhesive backing on the second side surface in the front-back upward direction.

[0007] In one embodiment, the second side plate is inclined upward from the bottom plate toward the outside of the adsorption member.

[0008] In one embodiment, the mounting device further includes a side-pressing assembly, which includes a first side-pressing block and a second side-pressing block. The first side-pressing block and the second side-pressing block are respectively laterally retractable to the adsorption member, such that the side-pressing assembly has a retracted state in which the first side-pressing block and the second side-pressing block are respectively retracted into the adsorption member, and an extended state in which the first side-pressing block extends outward from the first side plate, and the second side-pressing block extends outward from the second side plate.

[0009] In one embodiment, the side-pressing assembly further includes a gripper cylinder, which is drivenly connected to the first side-pressing block and the second side-pressing block respectively, so as to drive the first side-pressing block and the second side-pressing block to move closer or further away from each other, so that the side-pressing assembly switches between the retracted state and the extended state.

[0010] In one embodiment, the front end of the liner paper has a top surface, and the rear end of the liner paper is open. The adsorption element also has a top plate for attaching to the top surface; The mounting device further includes a base and a front and rear drive mechanism disposed on the base. The mounting seat is movably disposed on the base in the front and rear direction. The front and rear drive mechanism is used to drive the mounting seat to move back and forth, so that the adsorption member has a travel distance from the open side of the backing paper to move backward.

[0011] In one embodiment, the mounting device includes a fixed base on which the adsorption element is mounted. The fixed base is slidably disposed on the mounting base in a vertical direction. The vertical driving mechanism is drivenly connected to the fixed base so that the adsorption element moves vertically between the first working position and the second working position. The adsorption element includes a central portion and a peripheral portion surrounding the central portion. The bottom plate is located in the central portion, and the top plate, the first side plate, and the second side plate are located in the peripheral portion. The central portion is slidably mounted on the fixed base in the vertical direction, and the peripheral portion is fixed to the fixed base. The fixed base is also provided with a vertical driving mechanism, which is drivenly connected to the central portion and used to drive the central portion to move up and down relative to the fixed base.

[0012] In one embodiment, the fixed base is provided with a guide groove, and a lifting block is provided on the upper side of the central part. The lifting block is movably inserted through the guide groove in the vertical direction. The vertical drive mechanism drives and connects the lifting block. The inner top wall of the guide groove is used to abut against the lifting block to limit the upward movement of the central part relative to the fixed base.

[0013] In one embodiment, the lifting block has a first lifting portion and a second lifting portion disposed on both sides of the guide groove. A spring extending vertically is provided between the upper side of the first lifting portion and the fixed seat. The second lifting portion is used for transmission connection to the vertical drive mechanism.

[0014] In one embodiment, the mounting device further includes a lateral adjustment mechanism, which includes an adjustment seat disposed on the base and an adjustment member for mounting on the support structure. The relative position of the adjustment member and the adjustment seat in the lateral direction is adjustable, so that the relative position of the base and the adjustment member in the lateral direction is adjustable.

[0015] The technical solution provided by this invention has the following advantages: The present invention provides a mounting device for mounting backing paper into a box. The mounting device includes a mounting base, an adsorption element, and a vertical driving mechanism. The adsorption element is movably mounted on the mounting base in a vertical direction. The surface of the adsorption element is provided with suction nozzles. The adsorption element includes a bottom plate and a first side plate. The suction nozzles are distributed at least on the first side plate. The bottom plate is used to attach the bottom surface, and the first side plate is used to attach the first side surface. The first side plate is inclined from the bottom plate upward toward the inside of the adsorption element. The vertical driving mechanism is mounted on the mounting base and drivenly connected to the adsorption element. It is used to drive the adsorption element to move vertically relative to the mounting base, so that the adsorption element has a first working position located inside the box and a second working position located above the box. Under the drive of the vertical driving mechanism, the adsorption element has a downward pressing stroke from the opening into the box and an upward moving stroke to separate from the box and the backing paper. In the embodiments provided by the present invention, the adsorbent is adsorbed with the backing paper. The up-down driving mechanism drives the adsorbent to press down into the box or move up to separate from the backing paper. Since the first side plate is inclined from the bottom plate to the inside of the adsorbent, the first side with the adhesive backing is not easy to stick to the box during the downward pressing process, reducing the situation of the backing paper not being properly adhered. After the first side is adhered to the inner wall of the box, the up-down driving mechanism drives the adsorbent to move up to separate from the backing paper. Since the first side plate of the adsorbent is inclined, it is not easy to rub against the adhered backing paper during its upward movement, reducing the phenomenon of the backing paper falling off or being damaged after being rubbed. In this way, the backing paper is applied, improving the product qualification rate. Attached Figure Description

Detailed Implementation

[0019] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0020] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0021] Please see Figures 1 to 6 This invention provides a mounting device 100 for mounting a backing paper 300 inside a box body 200. Specifically, the box body 200 has an opening on its upper side, and the backing paper 300 has a bottom surface 301 and a first side surface 302, the first side surface 302 being provided with adhesive backing. It should be noted that the orientation of the mounting device 100 provided by this invention is shown by the arrows in the figure. This orientation reference applies to the normal operation of the mounting device 100 and is not applicable during production, assembly, transportation, or other processes. In this embodiment, the up-down direction refers to the direction in which the backing paper 300 moves towards the opening side of the box body 200, causing the backing paper 300 to be pressed into the box body 200 from the opening side. Preferably, the up-down direction is approximately parallel to the direction of gravity. In other embodiments, the up-down direction can also be adaptively adjusted according to the way the backing paper 300 is pressed down. The lateral and front-back directions are approximately perpendicular to each other and both are approximately perpendicular to the up-down direction, wherein the lateral direction refers to the normal direction of the first side surface 302 with adhesive backing.

[0022] Please continue reading. Figure 6 and Figure 7 The mounting device 100 is used to press the adsorbed backing paper 300 downwards into the box body 200 from the open side to complete the mounting work. The backing paper 300 has at least a bottom surface 301 and a first side surface 302 coated with adhesive. In a preferred embodiment, the backing paper 300 also has a second side surface 303 that is laterally opposite to the first side surface 302. In a more preferred embodiment, the backing paper 300 also has a top surface 304. Preferably, the backing paper 300 is open at the end opposite to the end with the top surface 304, so that the adsorbent 2 can be removed from the open side of the backing paper 300 without interfering with the top surface 304.

[0023] In the embodiments provided by this invention, the mounting device 100 includes a mounting base 1, an adsorption element 2, and a vertical driving mechanism 4. The method by which the adsorption element 2 adsorbs the backing paper 300 is not limited; for example, it can utilize negative pressure adsorption, electrostatic adsorption, or magnetic adsorption. In this embodiment, the surface of the adsorption element 2 is provided with a suction nozzle, which is connected to a negative pressure pipeline to achieve separable adsorption of the backing paper 300. Further, please refer to... Figure 1 The adsorption element 2 is movably mounted on the mounting base 1 along its vertical direction. The surface of the adsorption element 2 is provided with suction nozzles. The adsorption element 2 includes a base plate 21 and a first side plate 22. Suction nozzles are at least distributed on the first side plate 22. The base plate 21 is used to attach to the bottom surface 301, and the first side plate 22 is used to attach to the first side surface 302. The first side plate 22 is inclined upwards from the base plate 21 towards the inner side of the adsorption element 2. Please refer to the following reference. Figures 1 to 3 After the first side plate 22 is inclined, it forms a non-right angle with the bottom plate 21. As shown in the figure, the outer side of the first side plate 22 forms an obtuse angle with the bottom plate 21, so that a gap is formed between the outer side of the first side plate 22 and the inner wall of the box 200. The up-down driving mechanism 4 is provided on the mounting base 1 and is drivenly connected to the adsorption member 2. It is used to drive the adsorption member 2 to move up and down relative to the mounting base 1, so that the adsorption member 2 has a first working position inside the box 200 and a second working position above the box 200. Thus, under the drive of the up-down driving mechanism 4, the adsorption member 2 has a downward stroke from the second working position to the first working position, that is, a downward stroke from the opening of the box 200 to the inside of the box 200, and an upward stroke from the first working position to the second working position, that is, an upward stroke from the box 200, thereby separating from the box 200 and the liner paper 300. In this embodiment, the adsorption member 2 adsorbs the backing paper 300. The up-down driving mechanism 4 drives the adsorption member 2 to press down into the box body 200 or move up to separate from the backing paper 300. Since the first side plate 22 is inclined inward from the bottom plate 21, the first side 302 with adhesive backing is not easy to adhere to the box body 200 during the pressing process, reducing the situation where the backing paper 300 is not properly adhered. After the first side 302 is adhered to the inner side wall of the box body 200, the up-down driving mechanism 4 drives the adsorption member 2 to move up to separate from the backing paper 300. Since the first side plate 22 of the adsorption member 2 is inclined, it is not easy to rub against the adhered backing paper 300 during its upward movement, reducing the phenomenon of the backing paper 300 falling off or being damaged after being rubbed. In this way, the backing paper 300 is attached, improving the product qualification rate.

[0024] Based on the previous embodiment, the outer side of the first side 302 of the backing paper 300 may be fully coated with adhesive, or it may have adhesive partially applied. Please refer to the previous embodiment for further details. Figure 2 and Figure 3In another embodiment of the present invention, the liner paper 300 further has a second side 303 disposed laterally opposite to the first side 302, and the second side 303 is partially provided with adhesive backing. Thus, a gap can be maintained between the second side 303 and the corresponding inner wall of the box body 200 through other means. Specifically, please continue reading. Figure 2 and Figure 3 The adsorption member 2 also has a second side plate 23 that is arranged opposite to the first side plate 22 in the lateral direction. The second side plate 23 is provided with suction nozzles. The second side plate 23 is used to attach the second side surface 303. An inner support block 231 is protruding from the outer side of the second side plate 23. The inner support block 231 is arranged to be staggered from the adhesive backing on the second side surface 303 in the front-back upward direction. In this embodiment, during the downward or upward movement of the adsorption member 2, the outer surface of its protruding inner support block 231 is higher than the outer surface of the second side plate 23. The inner support block 231 abuts against the inner side of the box body 200 and the corresponding inner side of the second side 303, so that the outer side of the backing paper 300 and the outer side of the box body 200 are kept apart. This makes it difficult for the second side 303 with adhesive backing to adhere to the box body 200 during the downward movement, reducing the situation where the backing paper 300 is not properly bonded. After the second side 303 is bonded to the inner side wall of the box body 200, the up and down driving mechanism 4 drives the adsorption member 2 to move upward and separate from the backing paper 300. Due to the spacing effect of the inner support block 231, it is not easy for the adsorption member 2 to rub against the bonded backing paper 300 during the upward movement, reducing the phenomenon of the backing paper 300 falling off or being damaged after being rubbed. In this way, the backing paper 300 is attached, improving the product qualification rate.

[0025] In the preferred embodiment, please continue reading Figure 3 The second side plate 23 is inclined upwards from the base plate 21 towards the outside of the adsorption member 2. Thus, the angle between the outer surface of the second side plate 23 and the base plate 21 is acute, which facilitates demolding of the adsorption member 2 during the molding process and reduces production costs.

[0026] In order to achieve reliable adhesion between the first side 302 and the second side 303 and the inner wall of the box 200 after the adsorption element 2 is pressed into the box 200, in a preferred embodiment, please refer to [the following text is missing]. Figures 1 to 3 The mounting device 100 further includes a side-pressing assembly 3, which includes a first side-pressing block 31 and a second side-pressing block 32. The first side-pressing block 31 and the second side-pressing block 32 are respectively laterally retractable to the adsorption member 2, such that the side-pressing assembly 3 has a retracted state in which the first side-pressing block 31 and the second side-pressing block 32 are respectively retracted into the adsorption member 2, and an extended state in which the first side-pressing block 31 extends outward from the first side plate 22, and the second side-pressing block 32 extends outward from the second side plate 23. In this embodiment, as... Figure 7As shown, after the liner paper 300 is pressed into the box body 200, the first side pressing block 31 and the second side pressing block 32 switch from the retracted state to the extended state, pushing the corresponding first side 302 and the second side 303 outward to adhere to the corresponding inner wall of the box body 200. During the adhesion process, the adsorption member 2 can maintain a gap with the first side 302 and the second side 303. During the upward movement of the adsorption member 2, it is not easy to rub against the adhered liner paper 300, reducing the phenomenon of the liner paper 300 falling off or being damaged after being rubbed. In this way, the liner paper 300 is installed, improving the product qualification rate.

[0027] There are various ways to realize the movement of the first side pressure block 31 and the second side pressure block 32. In a preferred embodiment, the side pressure assembly 3 further includes a gripper cylinder 33, which is drivenly connected to the first side pressure block 31 and the second side pressure block 32 respectively, so as to drive the first side pressure block 31 and the second side pressure block 32 to move closer or further away from each other, so that the side pressure assembly 3 switches between the retracted state and the extended state. In this way, the extension and retraction of the first side pressure block 31 and the second side pressure block 32 are realized through a simple and reliable drive structure. The structure is simple, the production cost is low, and the first side pressure block 31 and the second side pressure block 32 have good synchronization of movement, are easy to control, and have a fast production cycle.

[0028] For further information, please refer to [link / reference]. Figure 5 The front end of the backing paper 300 has a top surface 304, and the rear end of the backing paper 300 is open. The adsorption member 2 also has a top plate 24 for attaching the top surface 304, and preferably the top plate 24 is also provided with suction nozzles to adsorb the top surface 304 by using negative pressure.

[0029] Please continue reading. Figures 1 to 3 The mounting device 100 further includes a base 7 and a front-rear drive mechanism 5 disposed on the base 7. The mounting base 1 is movably disposed on the base 7 in the front-rear direction. The front-rear drive mechanism 5 is used to drive the mounting base 1 to move back and forth, so that the adsorbent 2 has a travel stroke that moves backward from the open side of the backing paper 300. In this embodiment, after the up-down drive mechanism 4 drives the adsorbent 2 to complete the downward stroke, before the adsorbent 2 enters the upward stroke, in order to completely separate the adsorbent 2 from the backing paper 300, the front-rear drive mechanism 5 can drive the adsorbent 2 to move backward a certain distance, so that the adsorbent 2 exits from the open side of the backing paper 300 until the top plate 24 of the adsorbent 2 is offset from the top surface 304 of the backing paper 300 in the front-rear direction. Then the up-down drive mechanism 4 drives the adsorbent 2 to perform the upward stroke, completely separating it from the backing paper 300 and the box body 200. It is understandable that before the next downward stroke, the front and rear drive mechanism 5 should drive the mounting base 1 to move forward so that the liner 300 and the open side of the box 200 are directly facing each other in the vertical direction, so as to facilitate the next downward stroke.

[0030] Based on the previous embodiment, the following problem exists: during the process of the front and rear drive mechanism 5 driving the adsorption member 2 to move backward, if there is no gap between the base plate 21 and the bottom surface 301 of the liner paper 300, the adsorption member 2 may drag the liner paper 300, affecting the product qualification rate. Therefore, in the preferred embodiment, please continue to refer to... Figure 4 and Figure 5 The mounting device 100 includes a fixed base 8 on which the adsorption member 2 is mounted. The fixed base 8 is slidably disposed on the mounting base 1 in the vertical direction. The vertical driving mechanism 4 is drivenly connected to the fixed base 8 so that the adsorption member 2 moves vertically between the first working position and the second working position, realizing the downward pressure stroke or the upward movement stroke of the adsorption member 2. The adsorption member 2 includes a central part 25 and a peripheral part 26 surrounding the central part 25. The bottom plate 21 is disposed on the central part 25, and the top plate 24, the first side plate 22 and the second side plate 23 are disposed on the peripheral part 26. The central part 25 is slidably mounted on the fixed base 8 in the vertical direction, and the peripheral part 26 is fixed to the fixed base 8. The fixed base 8 is also provided with a vertical driving mechanism 6, which is drivenly connected to the central part 25 and is used to drive the central part 25 to move vertically relative to the fixed base 8. In this embodiment, before the front and rear drive mechanism 5 drives the mounting base 1 to move backward, the vertical drive mechanism 6 drives the central part 25 upward, so that a gap is formed between the lower side of the base plate 21 and the bottom surface 301 of the backing paper 300. Thus, when the suction member 2 moves backward relative to the backing paper 300, it is less likely to rub against the bottom surface 301 of the backing paper 300, improving the product qualification rate. Preferably, the base plate 21 is provided with a suction nozzle for adsorbing the bottom surface 301. The vertical drive mechanism 6 drives the central part 25 upward, so that a gap is formed between the bottom of the suction nozzle on the base plate 21 and the bottom surface 301 of the backing paper 300. Preferably, the side pressure assembly 3 is provided together with the outer peripheral part 26 on the fixing base 8. In this case, the vertical drive mechanism 6 only needs to drive the central part 25 to move slightly upward, the load on the vertical drive mechanism 6 is small, and therefore it can be set to a smaller size, making the overall structure of the mounting device 100 more compact.

[0031] For further information, please refer to [link / reference]. Figure 4 and Figure 5The fixed base 8 has a guide groove 81, and the upper side of the central part 25 has a lifting block 251. The lifting block 251 is movably inserted through the guide groove 81 in a vertical direction. The vertical drive mechanism 6 drives and connects to the lifting block 251. The inner top wall of the guide groove 81 abuts against the lifting block 251 to limit the upward movement of the central part 25 relative to the fixed base 8. In this way, the guide groove 81 serves two purposes: firstly, it guides the vertical movement of the adsorption member 2 relative to the base; secondly, it limits the upward movement of the adsorption member 2 to prevent it from moving too high and colliding with the top surface 304 of the liner paper 300, which could cause damage to the liner paper 300.

[0032] For more information, please continue reading. Figure 5 The lifting block 251 has a first lifting part 2511 and a second lifting part 2512 respectively disposed on both sides of the guide groove 81. A spring 10 extending vertically is provided between the upper side of the first lifting part 2511 and the fixed base 8. The second lifting part 2512 is used for transmission connection to the vertical drive mechanism 6. In this way, the central part 25 and the bottom plate 21 disposed on it are elastically supported on the fixed base 8. On the one hand, when the adsorption member 2 is pressed down from the second working position to the first working position, the spring 10 plays a certain buffering role, which can protect the liner paper 300 and the box body 200 from being damaged due to excessive pressure. On the other hand, the spring 10 also plays the role of providing a restoring force. After the vertical drive mechanism 6 drives the central part 25 to move up a small stroke, the elastic member drives the central part 25 to return to the initial position.

[0033] It is understood that elastic elements are prone to deformation after prolonged use, affecting the performance of the mounting device 100. Therefore, in the preferred embodiment, please refer to [the following text is missing]. Figure 5The second lifting part 2512 is connected to the vertical drive mechanism 6 via a transmission member 61. Specifically, the second lifting part 2512 has a downward driving surface, and the transmission member 61 has a corresponding upward driving mating surface. The driving surface and the driving mating surface abut in the vertical direction. In this way, the initial position of the transmission member 61 can be limited by controlling the vertical drive mechanism 6. When the transmission member 61 is in the initial position, the central part 25 has not yet been lifted upward. At this time, the transmission member 61 supports the central part 25 through the driving mating surface, so that the suction nozzle on the bottom plate 21 is kept at least not lower than the bottom surface 301 of the outer part 26. When the upper and lower drive mechanism 4 drives the suction member 2 to press down, the bottom surface 301 of the liner paper 300 adsorbed by the bottom plate 21 can contact the bottom wall of the box body 200. When the suction member 2 is pressed down, since the transmission member 61 does not limit the second lifting part 2512 to move upward, the central part 25 can float elastically under the support of the spring 10, so as not to damage the bottom surface 301 of the liner paper 300 and the box body 200. Before the front and rear drive mechanism 5 drives the adsorption component 2 to move backward, the vertical drive mechanism 6 drives the transmission component 61 to move upward. At this time, the drive mating surface engages with the drive surface, lifting the second lifting part 2512 upward. That is, the lifting block 251, the center part 25, and the base plate 21 on it are lifted together, so that a gap is formed between the suction nozzle on the lower side of the base plate 21 and the bottom surface 301 of the liner paper 300. Then, the front and rear drive mechanism 5 drives the mounting base 1 to move backward, so that the adsorption component 2 avoids the top surface 304 of the liner paper 300. Finally, the upper and lower drive mechanism 4 drives the base to move upward, causing the adsorption component 2 to move upward as a whole and separate from the liner paper 300 and the box body 200.

[0034] Ideally, the transmission component 61 is configured such that when the adsorption component 2 is in the second working position, the lower side of the base plate 21 is located below the outer periphery 26. Thus, when the adsorption component 2 moves from the second working position to the first working position, the lower side of the base plate 21 first abuts against the box body 200, and the spring 10 is compressed and deformed until the lower side of the base plate 21 is flush with the outer periphery 26. This ensures that the bottom surface 301 of the liner paper 300 is in full contact with the inner side of the bottom wall of the box body 200, making the adhesion and fixation of the liner paper 300 to the box body 200 more secure and reliable.

[0035] In one embodiment, please continue to refer to Figures 1 to 4 The mounting device 100 further includes a lateral adjustment mechanism 9, which includes an adjustment seat 91 disposed on the base 7 and an adjustment member 92 for mounting on the support structure. The relative position of the adjustment member 92 and the adjustment seat 91 in the lateral direction is adjustable, so that the relative position of the base 7 and the adjustment member 92 in the lateral direction is adjustable.

[0036] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. Based on the embodiments of the present invention, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the scope of protection of the present invention.
