Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to a material carrier mechanism and a film conveying device. Background Technology

[0002] When battery cells are stacked to form a battery cell module, a film is inserted between adjacent cells. The film bonds the adjacent cells together and also protects them. In existing technology, the film is generally transported to the battery cell stacking station via a conveyor line. To ensure that the film moves stably with the conveyor line, pairs of limiting blocks are set on the conveyor surface of the conveyor line. Each film is confined between the pairs of limiting blocks, keeping the film and the conveyor surface of the conveyor line relatively fixed.

[0003] However, there are currently various specifications of battery cells, each corresponding to a different film size. When the conveyor line needs to transport films of different specifications, the spacing between pairs of limit blocks needs to be adjusted to match the corresponding films. Currently, the limit blocks on the conveyor line can only be adjusted manually, which is cumbersome and results in low production efficiency. Utility Model Content

[0004] The primary objective of this application is to provide a material-carrying mechanism to solve the technical problem in the prior art where film conveyor lines require manual adjustment of limit blocks when conveying films of different sizes, resulting in cumbersome operation and low production efficiency.

[0005] To achieve the above objectives, this application adopts the following technical solution: A material loading mechanism includes a mounting base, a support platform disposed on the mounting base, and a horizontal drive assembly, wherein: The number of carrier platforms is one, two or more. Each carrier platform includes a first side plate, a second side plate, a reference side plate and a pusher side plate. The first side plate and the second side plate are arranged opposite each other along a first horizontal direction, and the reference side plate and the pusher side plate are arranged opposite each other along a second horizontal direction. The first side plate, the second side plate, the reference side plate and the pusher side plate together form a material loading area for placing film. The first horizontal direction and the second horizontal direction are perpendicular to each other. The horizontal drive assembly is configured to drive the first and second side plates in each carrier to move toward or away from each other, and to drive the pusher side plate in each carrier to approach or move away from the reference side plate.

[0006] Using the material loading mechanism provided in this application, when it is necessary to change films of different sizes, the horizontal drive assembly is controlled to drive the first and second side plates in each support platform to move towards or away from each other, and to drive the pushing side plates in each support platform to approach or move away from the reference side plate. This automatically adjusts the size of the material loading area formed by the combined side plates, ensuring that the size of the loading area matches the size of the film to be carried. This material loading mechanism can replace manual adjustment of the loading area when changing films of different sizes, improving the automation level of the production line and increasing production efficiency.

[0007] In some embodiments, when the number of support platforms is two or more, each support platform is arranged side by side along a first horizontal direction, and the reference planes of each reference side plate are on the same straight line extending along the first horizontal direction.

[0008] The reference surface of the reference side plate is used as a reference plane when positioning the film. Since all reference surfaces are on the same straight line extending along the first horizontal direction, each reference surface provides a unified positioning reference for the film in different material loading areas, which facilitates the accurate loading and unloading of the film.

[0009] In some embodiments, the horizontal drive assembly includes a first drive source, the power output end of which is connected to all the first side plates and all the second side plates in a transmission connection, so that all the first side plates and all the second side plates can be driven to move simultaneously through a first drive source.

[0010] In some embodiments, the horizontal drive assembly includes a second drive source, the power output end of which is connected to all the pusher side plates in a transmission connection, so that all the pusher side plates can be driven to move simultaneously through a second drive source.

[0011] In some embodiments, the horizontal drive assembly includes a first drive source and a second drive source, wherein the power output end of the first drive source is drivenly connected to all the first side plates and all the second side plates, and the power output end of the second drive source is drivenly connected to all the pusher side plates. The horizontal drive assembly can control all the first side plates, all the second side plates and all the pusher side plates to move simultaneously with only two drive sources, thereby simplifying the mechanism structure and reducing manufacturing costs.

[0012] In some embodiments, the horizontal drive assembly includes a first drive source and a first power output element, wherein: The first power output component includes a first transmission part and a second transmission part. The first transmission part is connected to all the first side plates in a transmission connection, and the second transmission part is connected to all the second side plates in a transmission connection. The first drive source is configured to drive the first transmission unit and the second transmission unit to output driving forces in opposite directions, so that the first side plate and the second side plate in each support platform move towards each other or away from each other.

[0013] When it is necessary to adjust the size of the loading area, the first drive source is controlled to drive the first transmission unit and the second transmission unit to output driving forces in opposite directions. At this time, the first transmission unit drives all the first side plates to approach or move away from the corresponding second side plates, and the second transmission unit drives all the second side plates to approach or move away from the corresponding first side plates, so that the first side plates and the second side plates in each support platform move towards each other or away from each other.

[0014] In some embodiments, the first power output component is an annular belt, the first transmission part and the second transmission part are respectively the first side belt body and the second side belt body of the annular belt, the first transmission part is fixedly connected to all the first side plates, and the second transmission part is fixedly connected to all the second side plates. Alternatively, the first power output component is a ring chain, the first transmission part and the second transmission part are respectively the first side chain and the second side chain of the ring chain, the first transmission part is fixedly connected to all the first side plates, and the second transmission part is fixedly connected to all the second side plates; Alternatively, the first power output component is a two-way lead screw, and the first transmission part and the second transmission part are respectively the first part screw and the second part screw of the two-way lead screw, and the threads on the circumferential surfaces of the first transmission part and the second transmission part have opposite directions; the first transmission part is threaded with all the first side plates, and the second transmission part is threaded with all the second side plates.

[0015] All three structural forms of the first power output component described above can enable the first transmission part and the second transmission part to output driving forces in opposite directions under the drive of the first driving source, so that the first side plate and the second side plate in each support platform can move towards each other or away from each other.

[0016] In some embodiments, the horizontal drive assembly includes a second drive source and a second power output element, wherein: The second power output component is a ball screw assembly. The screw of the second power output component extends along the second horizontal direction, and the nut of the second power output component is fixedly connected to all the pusher side plates. The second drive source is configured to drive the screw of the second power output component to rotate about its own axis.

[0017] When the second drive source drives the screw of the second power output component to rotate around its own axis, the nut of the second power output component drives all the pusher side plates to move along the second horizontal direction, so that each pusher side plate approaches or moves away from the corresponding reference side plate.

[0018] In some embodiments, the horizontal drive assembly further includes a first linkage member, which is fixedly connected to all the first side plates; And / or, the horizontal drive assembly also includes a second linkage member, which is fixedly connected to all the second side plates; And / or, the horizontal drive assembly also includes a third linkage, which is fixedly connected to all the pusher side plates.

[0019] The first linkage component enables all the first side plates to move synchronously, the second linkage component enables all the second side plates to move synchronously, and the third linkage component enables all the pushing side plates to move synchronously.

[0020] In some embodiments, each support platform further includes a support base plate that is slidable relative to the mounting base in a second horizontal direction, and a pusher side plate is fixed to the support base plate. The first side plate and the second side plate are located on both sides of the support base plate along the first horizontal direction, and both the first side plate and the second side plate can slide relative to the mounting base along the first horizontal direction. There are two reference side plates on each support platform, with the two reference side plates respectively set on the first side plate and the second side plate.

[0021] In the above structure, when the first side plate and the second side plate move towards or away from each other along the first horizontal direction, the two reference side plates also move towards or away from each other along the first horizontal direction, but the two reference side plates do not move in other directions. When the supporting base plate slides relative to the mounting seat along the second horizontal direction, the pushing side plate, driven by the supporting base plate, approaches or moves away from the two reference side plates along the second horizontal direction. The supporting base plate not only supports and transmits the pushing side plate, but also supports the film, making the film more stable during transportation.

[0022] In some embodiments, the first side plate is provided with a first horizontal surface and a first vertical surface, the first horizontal surface is located at the bottom of the material loading area, and the first vertical surface is located on the first side of the material loading area; The second side plate is provided with a second horizontal surface and a second vertical surface. The second horizontal surface is located at the bottom of the material loading area, and the second vertical surface is located on the second side of the material loading area.

[0023] After the film is placed in the loading area, the first horizontal plane and the second horizontal plane support the bottom of the film, and the first vertical plane and the second vertical plane abut against the two opposite sides of the film along the first horizontal direction, so that the film will not shift or shake relative to the support platform during the conveying process.

[0024] In some embodiments, the mounting base is provided with a first guide rail extending along a first horizontal direction, and each first side plate and each second side plate are slidably disposed on the first guide rail; And / or, the mounting base is provided with a second guide rail extending along a second horizontal direction, and each pusher side plate is slidably mounted on the second guide rail.

[0025] The first guide rail is used to limit the movement trajectory of each first side plate and each second side plate, and the second guide rail is used to limit the movement trajectory of each pusher side plate.

[0026] A second objective of this application is to provide a film conveying device comprising two conveying tracks, a feeding drive mechanism, and two loading mechanisms as described above, each loading mechanism further comprising a base and a lifting drive source, wherein: The mounting base is slidably mounted on the base in the vertical direction, and the lifting drive source is configured to drive the mounting base to move in the vertical direction relative to the base; Two bases are slidably mounted on two conveying tracks, which extend along the first horizontal direction. Each support platform is located between the two conveying tracks. The feeding drive mechanism is configured to drive the two material-carrying mechanisms to slide horizontally along their respective conveying tracks.

[0027] During operation, the film conveying device has a loading end and a unloading end at its two ends along the first horizontal direction. Two loading mechanisms slide back and forth on corresponding conveying tracks, alternating between moving to the loading end and then to the unloading end. When one loading mechanism moves to the loading end, the other moves to or near the unloading end. The loading mechanism at the loading end receives the film removed from the cassette, while the unloading mechanism awaits the subsequent process to transfer the film it carries. The alternating loading and unloading of the two loading mechanisms improves conveying efficiency.

[0028] In some embodiments, the loading areas on the two loading mechanisms are located on the same straight line extending along a first horizontal direction; Each reference side plate of the first material loading mechanism is located at the end of the corresponding support platform away from its own mounting base, and each reference side plate of the second material loading mechanism is located at the end of the corresponding support platform closer to its own mounting base.

[0029] In the above structure, all reference side plates in the device have coplanar reference surfaces, providing a unified positioning reference for the film in different material loading areas. Furthermore, setting each material loading area to be on the same straight line minimizes the distance between the two conveyor tracks, thus reducing the device's footprint. Since the vertical positions of the support platforms on the two material loading mechanisms can be adjusted by a third drive source, when the two material loading mechanisms move to interfere with each other, the support platform in one material loading mechanism is raised by the third drive source, while the support platform in the other material loading mechanism is lowered by the third drive source. This causes the support platforms in the two material loading mechanisms to vertically intersect each other, eliminating the interference between the two material loading mechanisms and allowing them to transport normally along their corresponding conveyor tracks.

Detailed Implementation

[0033] The technical solutions of this application will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] It should be noted that in the description of this application, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] It should be noted that, in the description of this application, the terms "connection" and "installation" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through an intermediate medium; they can refer to a mechanical connection or an electrical connection. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0036] To address the technical problem that existing film conveyor lines require manual adjustment of limit blocks when conveying films of different sizes, resulting in cumbersome operation and low production efficiency, the first aspect of this application provides a material loading mechanism 1, referring to... Figure 1 and Figure 2 The material loading mechanism 1 includes a mounting base 14, a support platform 12 and a horizontal drive assembly 13 disposed on the mounting base 14, wherein: The number of support platforms 12 is one, two or more. Each support platform 12 includes a first side plate 121, a second side plate 122, a reference side plate 123 and a pusher side plate 124. The first side plate 121 and the second side plate 122 are arranged opposite to each other along a first horizontal direction, and the reference side plate 123 and the pusher side plate 124 are arranged opposite to each other along a second horizontal direction. The first side plate 121, the second side plate 122, the reference side plate 123 and the pusher side plate 124 together form a material loading area for placing the film 100. The first horizontal direction and the second horizontal direction are perpendicular to each other. The horizontal drive assembly 13 is configured to drive the first side plate 121 and the second side plate 122 in each of the carrier platforms 12 to move toward each other or away from each other, and to drive the pusher side plate 124 in each of the carrier platforms 12 to approach or move away from the reference side plate 123.

[0037] Using the material loading mechanism 1 provided in this application, when it is necessary to change to a film 100 of different sizes, the horizontal drive assembly 13 is controlled to drive the first side plate 121 and the second side plate 122 in each support platform 12 to move towards each other or away from each other, and to drive the pusher side plate 124 in each support platform 12 to approach or move away from the reference side plate 123. In this way, the size of the material loading area formed by the side plates can be automatically adjusted so that the size of the material loading area is adapted to the size of the film 100 to be carried. This material loading mechanism 1 can replace manual adjustment of the size of the material loading area when changing to a film 100 of different sizes, improving the automation level of the production line and increasing production efficiency.

[0038] Optionally, the number of carrier platforms 12 can be one, two, or more. The more carrier platforms 12 there are, the more films 100 can be transported at once. However, the number of carrier platforms 12 is also limited by other supporting components of the production line, and its number can be adjusted adaptively according to actual needs. In this embodiment, the number of carrier platforms 12 is specifically two.

[0039] In some embodiments, when the number of support platforms 12 is two or more, the support platforms 12 are arranged side by side along a first horizontal direction, and the reference planes of the reference side plates 123 are on the same straight line extending along the first horizontal direction. Figure 2 As shown, the reference surface of the reference side plate 123 is vertically arranged and close to the film 100. This reference surface is used as a reference plane when positioning the film 100. Since each reference surface is on the same straight line extending along the first horizontal direction (i.e., coplanar), each reference surface provides a unified positioning reference for the film 100 in different material loading areas, which facilitates the accurate placement and removal of the film 100.

[0040] In some embodiments, continue to refer to Figure 2 Each support platform 12 also includes a support base plate 125, which can slide relative to the mounting base 14 along the second horizontal direction. The pusher side plate 124 is fixed on the support base plate 125. The first side plate 121 and the second side plate 122 are located on both sides of the support base plate 125 along the first horizontal direction. Both the first side plate 121 and the second side plate 122 can slide relative to the mounting base 14 along the first horizontal direction. There are two reference side plates 123 on each support platform 12. The two reference side plates 123 are respectively set on the first side plate 121 and the second side plate 122.

[0041] In the above structure, when the first side plate 121 and the second side plate 122 move towards or away from each other along the first horizontal direction, the two reference side plates 123 also move towards or away from each other along the first horizontal direction, but the two reference side plates 123 do not move in other directions. When the supporting base plate 125 slides relative to the mounting base 14 along the second horizontal direction, the pushing side plate 124, driven by the supporting base plate 125, approaches or moves away from the two reference side plates 123 along the second horizontal direction. The supporting base plate 125 not only supports and transmits the pushing side plate 124, but also supports the film 100, making the film 100 more stable during the conveying process.

[0042] In some embodiments, the first side plate 121 has a first horizontal surface and a first vertical surface, the first horizontal surface being located at the bottom of the material-carrying area and the first vertical surface being located on the first side of the material-carrying area; the second side plate 122 has a second horizontal surface and a second vertical surface, the second horizontal surface being located at the bottom of the material-carrying area and the second vertical surface being located on the second side of the material-carrying area. The first side and the second side of the material-carrying area are two opposite sides along the first horizontal direction. After the film 100 is placed in the material-carrying area, the first horizontal surface and the second horizontal surface support the bottom of the film 100, and the first vertical surface and the second vertical surface abut against the two sides of the film 100 along the first horizontal direction, respectively. The reference surface of the reference side plate 123 and the pusher side plate 124 abut against the two sides of the film 100 along the second horizontal direction, thereby fixing the film 100 in the material-carrying area so that the film 100 will not shift or shake relative to the support platform 12 during the conveying process.

[0043] In some embodiments, continue to refer to Figure 1 The horizontal drive assembly 13 includes a first drive source 131. The power output end of the first drive source 131 is connected to all the first side plates 121 and all the second side plates 122. One first drive source 131 can drive all the first side plates 121 and all the second side plates 122 to move simultaneously, thereby simplifying the mechanism structure and reducing manufacturing costs. Of course, in other embodiments, the number of first drive sources 131 can be the same as the number of support platforms 12 and correspond one-to-one, with the power output end of each first drive source 131 connected to the corresponding first side plate 121 and second side plate 122.

[0044] In some embodiments, the horizontal drive assembly 13 includes a second drive source 132. The power output end of the second drive source 132 is connected to all the pusher side plates 124 in a transmission connection. All the pusher side plates 124 can be driven to move simultaneously by one second drive source 132, thereby further simplifying the mechanism structure and reducing manufacturing costs. Of course, in other embodiments, the number of second drive sources 132 can be the same as the number of support platforms 12 and correspond one-to-one, with the power output end of each second drive source 132 being connected to the corresponding pusher side plate 124.

[0045] In some embodiments, the horizontal drive assembly 13 includes a first drive source 131 and a second drive source 132, wherein the power output end of the first drive source 131 is connected to all the first side plates 121 and all the second side plates 122, and the power output end of the second drive source 132 is connected to all the pusher side plates 124. The horizontal drive assembly 13 can control all the first side plates 121, all the second side plates 122 and all the pusher side plates 124 to move simultaneously with only two drive sources.

[0046] In some embodiments, refer to Figure 3 The horizontal drive assembly 13 includes a first drive source 131 and a first power output component 133, wherein: The first power output component 133 includes a first transmission part 1331 and a second transmission part 1332. The first transmission part 1331 is connected to all the first side plates 121 in a transmission manner, and the second transmission part 1332 is connected to all the second side plates 122 in a transmission manner. The first drive source 131 is configured to drive the first transmission unit 1331 and the second transmission unit 1332 to output driving forces in opposite directions, so that the first side plate 121 and the second side plate 122 in each support platform 12 move toward each other or move away from each other.

[0047] When it is necessary to adjust the size of the loading area, the first drive source 131 is controlled to drive the first transmission unit 1331 and the second transmission unit 1332 to output driving forces in opposite directions. At this time, the first transmission unit 1331 drives all the first side plates 121 to approach or move away from the corresponding second side plates 122, and the second transmission unit 1332 drives all the second side plates 122 to approach or move away from the corresponding first side plates 121, so that the first side plates 121 and the second side plates 122 in each bearing platform 12 move towards each other or away from each other.

[0048] The first power output component 133 includes the following structural forms: The first structural form is: continue to refer to Figure 3The first power output component 133 is an annular belt. The first transmission part 1331 and the second transmission part 1332 are respectively the first side belt body and the second side belt body of the annular belt. The first transmission part 1331 is fixedly connected to all the first side plates 121, and the second transmission part 1332 is fixedly connected to all the second side plates 122. When the first drive source 131 drives the annular belt to rotate, the first transmission part 1331 and the second transmission part 1332 move in opposite directions, thereby outputting driving forces in opposite directions.

[0049] The second structural form is as follows: the first power output component is a ring chain, the first transmission part 1331 and the second transmission part 1332 are respectively the first side chain and the second side chain of the ring chain, the first transmission part 1331 is fixedly connected to all the first side plates 121, and the second transmission part 1332 is fixedly connected to all the second side plates 122. The transmission principle of the ring chain is similar to that of the ring belt.

[0050] The third structural form is as follows: the first power output component 133 is a bidirectional lead screw, the first transmission part 1331 and the second transmission part 1332 are respectively the first and second part screws of the bidirectional lead screw, and the threads on the circumferential surfaces of the first transmission part 1331 and the second transmission part 1332 have opposite directions of rotation; the first transmission part 1331 is threadedly engaged with all the first side plates 121, and the second transmission part 1332 is threadedly engaged with all the second side plates 122. Specifically, nuts are screwed onto the first transmission part 1331 and the second transmission part 1332 respectively. The nuts on the first transmission part 1331 are fixedly connected to all the first side plates 121, and the nuts on the second transmission part 1332 are fixedly connected to all the second side plates 122. When the first drive source 131 drives the bidirectional lead screw to rotate around its own axis, the nuts on the first transmission part 1331 and the nuts on the second transmission part 1332 move in opposite directions, thereby outputting driving forces in opposite directions.

[0051] All three structural forms described above can enable the first transmission unit 1331 and the second transmission unit 1332 to output driving forces in opposite directions under the drive of the first driving source 131, so that the first side plate 121 and the second side plate 122 in each support platform 12 can move towards each other or away from each other.

[0052] Specifically Figure 3In the illustrated embodiment, the first transmission part 1331 is the lower belt body of the annular belt, and the second transmission part 1332 is the upper belt body of the annular belt. The first drive source 131 is specifically a motor, and the body of the first drive source 131 is fixed on the mounting base 14. The horizontal drive assembly 13 also includes two first drive wheels 138, one of which is a driving wheel and is mounted on the output shaft of the motor, and the other is a driven wheel. The two first drive wheels 138 are respectively engaged with the two ends of the first transmission part 1331 and the second transmission part 1332.

[0053] Furthermore, at least one first side plate 121 is fixedly provided with a second clamping plate 126, which is clamped and fixed to the first transmission part 1331; at least one second side plate 122 is fixedly provided with a third clamping plate 127, which is clamped and fixed to the second transmission part 1332. The meaning of "at least one" above is: taking the first side plate 121 as an example, the second clamping plate 126 may be provided on only one of the first side plates 121, while the other first side plates 121 are all fixedly connected to the first side plate 121 provided with the second clamping plate 126; or the second clamping plate 126 may be provided on each of the first side plates 121.

[0054] In some embodiments, refer to Figure 3 and Figure 4 One of the first side plates 121 is provided with a second clamping plate 126, and the first side plate 121 is fixedly connected to the first transmission part 1331; the horizontal drive assembly 13 also includes a first linkage member 135, which is fixedly connected to all the first side plates 121. Specifically in Figure 4 In the embodiment shown, the first linkage 135 is located at one end of the support platform 12 near the mounting base 14. The first linkage 135 extends along the first horizontal direction and is sequentially fixedly connected to each of the first side plates 121 by bolts. The first linkage 135 enables all the first side plates 121 to move synchronously.

[0055] In some embodiments, a third clamping plate 127 is provided on one of the second side plates 122, and the second side plate 122 is fixedly connected to the second transmission part 1332; the horizontal drive assembly 13 further includes a second linkage member 136, which is fixedly connected to all the second side plates 122. The second linkage member 136 is located at one end of the support platform 12 near the mounting base 14, extends along a first horizontal direction, and is sequentially fixedly connected to each of the second side plates 122 by bolts, so that all the second side plates 122 move synchronously.

[0056] In some embodiments, the horizontal drive assembly 13 further includes a first linkage 135 and a second linkage 136. The first linkage 135 is fixedly connected to all the first side plates 121, and the second linkage 136 is fixedly connected to all the second side plates 122. The first linkage 135 and the second linkage 136 both extend along the first horizontal direction and are distributed vertically.

[0057] In some embodiments, in order to limit the movement trajectory of each first side plate 121 and each second side plate 122, refer to Figure 4 The mounting base 14 is provided with a first guide rail 16 extending along the first horizontal direction, and each first side plate 121 and each second side plate 122 are slidably mounted on the first guide rail 16. Figure 4 In the embodiment shown, a slider is fixed at one end of each first side plate 121 and each second side plate 122 near the mounting base 14, and the slider is slidably disposed on the first guide rail 16.

[0058] In some embodiments, continue to refer to Figure 2 The horizontal drive assembly 13 includes a second drive source 132 and a second power output component 134, wherein: the second power output component 134 is a ball screw assembly, the screw of the second power output component 134 extends along a second horizontal direction, and the nut of the second power output component 134 is fixedly connected to all the pusher side plates 124; the second drive source 132 is configured to drive the screw of the second power output component 134 to rotate about its own axis. Figure 2 In the illustrated embodiment, the second drive source 132 is a motor, and the body of the second drive source 132 is fixed on the mounting base 14. The horizontal drive assembly 13 also includes two second drive wheels 139 and an annular belt or annular chain wound around the two second drive wheels 139. One of the second drive wheels 139 is a driving wheel and is mounted on the output shaft of the motor, while the other second drive wheel 139 is coaxially fixed to the screw end of the second power output component 134. In addition to belt and gear transmission, the output shaft of the motor can also be directly coaxially fixed to the screw via a coupling.

[0059] In some other embodiments, the second drive source 132 is a cylinder, and the piston rod of the second drive source 132 extends along a second horizontal direction and is fixedly connected to all the pusher side plates 124. When the piston rod of the second drive source 132 extends or retracts, it drives all the pusher side plates 124 to reciprocate along the second horizontal direction. Compared with a cylinder as a drive source, a motor as a drive source offers higher controllability, and the ball screw assembly has higher transmission accuracy and a wider range of applications.

[0060] In some embodiments, the horizontal drive assembly 13 further includes a third linkage 137, which is fixedly connected to all the pusher side plates 124. For example... Figure 2As shown, the third linkage 137 is located at one end of the support platform 12 near the mounting base 14. The third linkage 137 extends along the first horizontal direction and is sequentially fixedly connected to each support base plate 125 by bolts, and then sequentially fixedly connected to the pusher side plates 124 on each support base plate 125. The third linkage 137 causes all the pusher side plates 124 to move synchronously. Furthermore, the nut of the second power output component 134 is embedded in the third linkage 137, realizing the fixed connection between the nut and all the pusher side plates 124.

[0061] In some embodiments, in order to limit the movement trajectory of each pusher side plate 124, a second guide rail 17 extending in the second horizontal direction is provided on the mounting base 14, and each pusher side plate 124 is slidably disposed on the second guide rail 17. Figure 2 In the embodiment shown, a slider is fixedly provided at the bottom of the third linkage 137, and the slider on the third linkage 137 is slidably disposed on the second guide rail 17.

[0062] In some embodiments, continue to refer to Figure 1 Each material handling mechanism 1 also includes a base 11 and a lifting drive source 15. The mounting base 14 is slidably disposed on the base 11 in a vertical direction, and the lifting drive source 15 is configured to drive the mounting base 14 to move vertically relative to the base 11. The purpose of providing the base 11 and the lifting drive source 15 is to make the vertical position of the mounting base 14 and its components adjustable to meet greater conveying needs.

[0063] In some embodiments, the lifting drive source 15 is a piston cylinder (which can be one of a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder). The cylinder body of the lifting drive source 15 is fixed on the base 11, and the piston rod of the lifting drive source 15 is fixedly connected to the mounting base 14. Alternatively, the lifting drive source 15 can also be a motor, and the output shaft of the lifting drive source 15 is fixedly connected to the mounting base 14 via a linear transmission structure such as a lead screw nut, gear rack, etc. (Continue referring to...) Figure 2 In order to limit the movement trajectory of the mounting base 14, a third guide rail 18 extending vertically is provided on the base 11, and the mounting base 14 is slidably mounted on the third guide rail 18.

[0064] A second aspect of this application provides a film transport device, referring to... Figure 5 The film conveying device includes two conveying tracks 2, a feeding drive mechanism 3, and two loading mechanisms 1 as described in any of the above embodiments. Each loading mechanism 1 further includes a base 11 and a lifting drive source 15, wherein: Mounting base 14 is slidably disposed on base 11 in a vertical direction, and lifting drive source 15 is configured to drive mounting base 14 to move in a vertical direction relative to base 11. Two bases 11 are slidably mounted on two conveying tracks 2, which extend along the first horizontal direction. Each support platform 12 is located between the two conveying tracks 2. The feeding drive mechanism 3 is configured to drive the two material carriers 1 to slide horizontally along their respective conveying tracks 2.

[0065] During operation, the film conveying device has a loading end and a unloading end at its two ends along the first horizontal direction. Two loading mechanisms 1 slide back and forth on corresponding conveying tracks 2, alternating between moving to the loading end and then to the unloading end. When one loading mechanism 1 moves to the loading end, the other moves to or near the unloading end. The loading mechanism 1 at the loading end receives the film 100 removed from the cassette, while the loading mechanism 1 at the unloading end awaits subsequent processes to transfer the film 100 it carries. The alternating loading and unloading by the two loading mechanisms 1 improves conveying efficiency.

[0066] In some embodiments, refer to Figure 6 The loading areas on the two loading mechanisms 1 are located on the same straight line extending along a first horizontal direction. The reference side plates 123 of the first loading mechanism 1 are located at the end of the corresponding support platform 12 furthest from its mounting base 14, while the reference side plates 123 of the second loading mechanism 1 are located at the end of the corresponding support platform 12 closest to its mounting base 14. In this structure, the reference surfaces of all the reference side plates 123 are coplanar, providing a unified positioning reference for the film 100 in different loading areas. Furthermore, by aligning the loading areas on the same straight line, the distance between the two conveyor tracks 2 can be minimized, thereby reducing the footprint of the device. Since the vertical position of the support platform 12 on the two material loading mechanisms 1 can be adjusted by the lifting drive source 15, when the two material loading mechanisms 1 move to interfere with each other, the support platform 12 in one material loading mechanism 1 is lifted by the lifting drive source 15, and the support platform 12 in the other material loading mechanism 1 is lowered by the lifting drive source 15, so that the support platforms 12 in the two material loading mechanisms 1 are staggered in the vertical direction, so as to eliminate the interference between the two material loading mechanisms 1 and allow the two material loading mechanisms 1 to transport normally along the corresponding conveying track 2.

[0067] In some embodiments, refer to Figure 1 and Figure 5Each base 11 is equipped with a first clamping plate 112. The feeding drive mechanism 3 includes two sets of feeding drive components 31, which correspond one-to-one with two conveying tracks 2. Each set of feeding drive components 31 includes a third drive source 311, a feeding drive wheel, a feeding driven wheel, and a feeding conveyor belt 312. Specifically, the third drive source 311 is a motor, and its body is mounted on one end of the device frame. The feeding drive wheel is fixedly mounted on the output shaft of the third drive source 311, and the feeding driven wheel is mounted on the other end of the device frame. The feeding conveyor belt 312 is wound around the feeding drive wheel and the feeding driven wheel, and the first clamping plate 112 clamps and fixes the corresponding feeding conveyor belt 312. The feeding conveyor belt 312 can also be replaced with a conveyor chain.

[0068] In some embodiments, continue to refer to Figure 1 Each base 11 has two first sliders 111 at its bottom. The two first sliders 111 are fixed on the horizontal mounting surface and the vertical mounting surface of the base 11, respectively, and the two first sliders 111 are slidably set on the corresponding conveying track 2.
