Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, and in particular to a semi-automatic battery plate stacking equipment. Background Technology

[0002] In the battery production process, battery plates include grids and lead paste coated on the grids. The battery plates are stacked manually to form plate stacks. The plate stacks are placed on a curing rack through a grid plate and then enter the curing chamber for curing. After curing is completed, the grid plate with the plate stacks is removed from the curing rack and finally transported to the battery assembly workshop for subsequent battery assembly production.

[0003] Currently, in existing technologies, electrode stacks typically need to be manually placed onto grating plates. Once the grating plates are full of electrode stacks, they also need to be manually placed onto the curing rack. However, manually placing the electrode stacks onto the grating plates is extremely labor-intensive. Furthermore, the curing rack has multiple layers for stacking the grating plates, and manually filling these layers with the grating plates that support the electrode stacks is also extremely labor-intensive and inefficient. Summary of the Invention

[0004] One of the objectives of this invention is to provide a semi-automatic battery electrode stacking device, which can not only automatically place electrode stacks on grid plates, but also automatically stack multiple grid plates carrying electrode stacks sequentially in the multi-layer space of a curing rack, thereby improving the efficiency of placing electrode stacks on the curing rack.

[0005] To achieve the above objectives, the present invention provides a semi-automatic battery plate stacking device, comprising:

[0006] Electrode stack conveying system, used to transport electrode stacks along a horizontal lateral movement;

[0007] An electrode plate stack loading and conveying system is arranged along the horizontal longitudinal direction on one side of the electrode plate stack conveying system. The electrode plate stack loading and conveying system is provided with a grid plate to be loaded onto the electrode plate stack. After the electrode plate stack is loaded onto the grid plate, it is conveyed horizontally through the electrode plate stack loading and conveying system.

[0008] A three-axis robot is used to load electrode stacks from the electrode stack conveying system onto the grid plate.

[0009] A transition conveying lifting system includes a lifting unit and a transition conveying device. The lifting unit and the transition conveying device are used to drive the transition conveying device to lift and lower. The transition conveying device extends horizontally and can be connected to the electrode plate stack loading conveying system. The transition conveying device is used to receive and convey the grating plates conveyed by the electrode plate stack loading conveying system.

[0010] A curing rack loading system is horizontally arranged at one end of the transition conveyor device opposite to the electrode plate stack loading and conveying system. The curing rack loading system is loaded with curing racks. The curing racks have multiple vertically spaced and interconnected spatial layers for stacking the grid plates.

[0011] The palletizing and conveying lifting system includes a stacking lifting mechanism and a palletizing conveying system. The stacking lifting mechanism is mounted on the curing rack loading system and is used to drive the palletizing conveying system to move up and down within multiple spatial layers. The palletizing conveying system can be connected to a transition conveying device. The palletizing conveying system is used to transport and place the grating plates delivered by the transition conveying device within the spatial layers. The palletizing conveying system places each grating plate sequentially in each spatial layer from top to bottom.

[0012] Furthermore, the electrode plate stack conveying system includes a first frame, a first drive unit, and at least two first conveying chains. The two first conveying chains are arranged side by side at intervals along the horizontal longitudinal direction and are driven on the first frame. The first drive unit is located on the first frame and is used to drive the two first conveying chains to drive synchronously. The two first conveying chains are respectively used to support the opposite sides of the electrode plate stack. The first frame is also provided with a first lifting mechanism, and the lifting end of the first lifting mechanism can extend vertically from the gap between the two first conveying chains.

[0013] Furthermore, the three-axis manipulator includes a fixed frame, a lateral movement module, a longitudinal movement module, a lifting module, a connecting seat, and a fork assembly. The fixed frame longitudinally spans the electrode plate stack conveying system. The lateral movement module is mounted on the fixed frame, the longitudinal movement module is mounted on the lateral movement module, the lifting module is mounted on the longitudinal movement module, the connecting seat is mounted on the lifting module, and the fork assembly is mounted on the connecting seat. The fork assembly includes two forks, which are used to support the electrode plate stack lifted by the first lifting mechanism. The two forks are also used to move the electrode plate stack they support to above the grid plate and place it on the grid plate.

[0014] Furthermore, the electrode plate stack loading and conveying system includes a second frame, a second drive unit, and two conveyor chain groups. The two conveyor chain groups are arranged side by side at intervals along the horizontal longitudinal direction and are driven on the second frame. The second drive unit is located on the second frame and is used to drive the two conveyor chain groups to drive synchronously. The two conveyor chain groups are respectively used to support the opposite sides of the grating plate. The grating plate is provided with two rows of clearance holes arranged at intervals along the horizontal longitudinal direction. The distance between the two rows of clearance holes is less than the width of the electrode plate stack in the horizontal longitudinal direction, and the distance between the two rows of clearance holes is greater than or less than the distance between the two forks. Each row of clearance holes includes multiple clearance holes, and each clearance hole penetrates the opposite surface of the grating plate vertically. A second lifting mechanism is provided on the second frame. The lifting end of the second lifting mechanism is provided with two rows of lifting bars. Each row of lifting bars includes multiple lifting bars, and the multiple lifting bars correspond one-to-one with the multiple clearance holes. The lifting bars can pass through the clearance holes vertically.

[0015] Furthermore, there are two electrode plate stack conveying systems, which are arranged side by side and spaced apart in the transverse direction. A three-axis robot is used to load the electrode plate stacks on the two electrode plate stack conveying systems onto the grid plate simultaneously.

[0016] Furthermore, each of the electrode plate stack loading and conveying system, the palletizing and lifting system, and the transition conveying and lifting system is provided in twos. Each electrode plate stack loading and conveying system is located on the outside of the electrode plate stacking and conveying system along the horizontal longitudinal direction. Each transition conveying device is connected to each electrode plate stack loading and conveying system. The curing rack loading system is equipped with two curing racks, each curing rack corresponding to each transition conveying device. The palletizing and conveying system of each palletizing and lifting system is used to transport the grating plates transported by each transition conveying device and place them in the spatial layer of each curing rack.

[0017] Furthermore, a grating plate feeding device is provided on the outer side of one of the transition conveying devices along the horizontal longitudinal direction. The grating plate feeding device is used to transport the grating plate of the electrode plate stack to be loaded along the horizontal longitudinal direction. A grating plate picking system is provided between the two transition conveying devices. The grating plate picking system is used to place the grating plate of the electrode plate stack to be loaded transported by the grating plate feeding device onto one of the two transition conveying devices. Each transition conveying device is also used to transport the grating plate of the electrode plate stack to be loaded into each electrode plate stack loading conveying system.

[0018] Furthermore, each of the aforementioned transition conveying devices is provided with a grating storage rack on its outer side along the horizontal longitudinal direction; the grating storage rack has multiple storage layers arranged at vertical intervals, the storage layers being used to store gratings for the electrode stacks to be loaded, and the grating material handling system is also used to store the electrode stacks to be loaded conveyed by the grating loading device in the storage layers on each of the aforementioned grating storage racks.

[0019] Furthermore, the grating material handling system includes a mounting frame, a lifting device, and a material handling device. The mounting frame is positioned between the two transition conveying devices, and the lifting device is mounted on the mounting frame to drive the material handling device to lift and lower. The material handling device includes a moving mechanism and two support plates. The moving mechanism is connected to the lifting device to enable the moving mechanism to lift and lower. The two support plates are spaced apart on the moving mechanism in a horizontal direction, and the distance between the two support plates is less than the length of the grating plate in the horizontal direction. The moving mechanism is used to drive the two support plates to move in a horizontal longitudinal direction so that the two support plates can move to the lower end of the grating plate loading device to lift the grating plate of the stack of electrode plates to be loaded on the grating plate loading device and store the lifted grating plate in the storage layer on the grating plate storage rack.

[0020] Furthermore, the grating material handling system also includes a rotating mechanism, which is mounted on the lifting device and is used to drive the material handling device to rotate.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] In use, the semi-automatic battery plate stacking equipment of the present invention involves manually placing the plate stacks onto the plate stack conveying system, which then horizontally transports the plate stacks. When the plate stacks reach a preset position at the end of the conveying system, a three-axis robotic arm loads them onto a grid plate of the loading conveying system. Once the grid plate is fully loaded with plate stacks by the robotic arm, it is horizontally transported through the loading conveying system and transferred to a transition conveying device. The transition conveying device then transports the grid plate to the stacking conveying system on the curing rack loading system. The curing rack has multiple spatial layers from top to bottom: a first spatial layer, a second spatial layer, a third spatial layer, etc. When a grid plate fully loaded with plate stacks needs to be transported and placed in the first spatial layer, it is transferred from the loading conveying system to the transition conveying device. The transition conveying device, driven by a lifting unit, rises to the corresponding position. In the first spatial layer, the palletizing and conveying system, driven by the stacking and lifting mechanism, is also located within this layer. This allows the grating plates loaded with electrode stacks to be transferred from the transition conveyor to the palletizing and conveying system, and then transported into the first spatial layer where they are supported. When it is necessary to transport and place the grating plates loaded with electrode stacks into the second spatial layer, the grating plates loaded with electrode stacks are transferred from the electrode stack loading and conveying system to the transition conveyor. The transition conveyor, driven by the lifting unit, rises to the corresponding second spatial layer. At this point, the palletizing and conveying system, driven by the stacking and lifting mechanism, is also located within the second spatial layer. This allows the grating plates loaded with electrode stacks to be transferred from the transition conveyor to the palletizing and conveying system, and then transported into the second spatial layer where they are supported. This process continues, automatically stacking multiple grating plates carrying electrode stacks into the multi-layered spatial layers on the curing rack, thus greatly improving the efficiency of placing electrode stacks on the curing rack.

Detailed Implementation

[0047] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0048] In the description of this invention, it should be understood that the terms "width", "upper", "lower", "front", "rear", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0049] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" 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 mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0050] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0051] Reference Figure 1 - Figure 22 The present invention provides a semi-automatic battery plate palletizing equipment, including a plate pallet conveying system 1, a plate pallet loading and conveying system 2, a three-axis robot 3, a transition conveying and lifting system 4, a grating plate loading device 5, a grating plate picking system 6, a curing rack loading system 7, and a palletizing and conveying lifting system 8.

[0052] Reference Figure 1 - Figure 4 Two electrode plate stack conveying systems 1 are provided, each independently configured and spaced apart along a horizontal longitudinal direction. Each system is used to transport electrode plate stacks 15 horizontally. Specifically, each system includes a first frame 10, a first drive unit 11, and at least two first conveyor chains 12. The two first conveyor chains 12 are spaced apart along a horizontal longitudinal direction and are driven onto the first frame 10. The first drive unit 11 is a servo motor, fixed to the first frame 10, and drives the two first conveyor chains 12 synchronously. The two first conveyor chains 12 respectively support the opposite sides of the electrode plate stack 15 in the horizontal longitudinal direction. In other words, the opposite sides of the electrode plate stack 15 are manually placed on the two first conveyor chains 12, and under the drive of the first drive unit 11, the electrode plate stack 15 is transported horizontally by the two first conveyor chains 12.

[0053] The first drive unit 11 can control the two first conveyor chains 12 to move intermittently or continuously. A worker stands at the front work station of the electrode plate stack conveying system 1. After the worker places the first stack of electrode plates 15 onto the two first conveyor chains 12 at the work station, the first drive unit 11 controls the two first conveyor chains 12 to move backward synchronously a short distance and then stop. Then the worker continues at the original work station to place the second stack of electrode plates 15 onto the two first conveyor chains 12. After the second stack of electrode plates 15 is placed, the first drive unit 11 again controls the two first conveyor chains 12 to move backward synchronously a short distance and then stop. Then the worker continues at the original work station to place the third stack of electrode plates 15 onto the two first conveyor chains 12, and so on in a cycle.

[0054] After a number of stacks of electrode plates 15 (e.g., 7 stacks of electrode plates 15) are placed horizontally and laterally on the two first conveyor chains 12 by manual labor, the first drive unit 11 controls the continuous movement of the two first conveyor chains 12 to transport the stacks of electrode plates 15 on the two first conveyor chains 12 to the preset position at the end of the electrode plate stack conveying system 1. Then, the three-axis robot 3 synchronously places the stacks of electrode plates 15 on the grid plate 9 of the two electrode plate stack conveying systems 1 onto the grid plate 9 of an electrode plate loading conveying system 2. It should be noted that the transmission of the first conveyor chains 12 on the first frame 10 is a conventional and existing structure in mechanical transmission, and will not be described in detail here.

[0055] For example, the first conveyor chain 12 has a sensor for detecting whether there are electrode plate stacks 15 placed on it. The sensor is electrically connected to the control system of the semi-automatic battery electrode plate stacking equipment. The control system can be an existing PLC control system, which will not be described here. For example, when the sensor detects that there are 7 stacks of electrode plates 15 on the first conveyor chain 12, the first drive unit 11 controls the two first conveyor chains 12 to move continuously. The sensor can be a weighing sensor. Since the weight of each electrode plate stack 15 is the same, the number of electrode plate stacks 15 on the first conveyor chain 12 can be determined by determining the weight of the electrode plate stacks 15 on the first conveyor chain 12. Alternatively, the number of electrode plate stacks 15 on the first conveyor chain 12 can also be determined by determining the number of steps of the first conveyor chain 12. The time interval of the steps of the first conveyor chain 12 is controlled by the control system.

[0056] Reference Figure 1 - Figure 7In order to facilitate the transfer of the electrode stack 15 on the first conveyor chain 12 to the grid plate 9 on the electrode stack loading and conveying system 2 by the three-axis robot 3, a first lifting mechanism 13 is also provided on the first frame 10 at the preset position at the end of the electrode stack conveying system 1. The first lifting mechanism 13 is fixed on the first frame 10 and is located below the first conveyor chain 12. The lifting end of the first lifting mechanism 13 can extend vertically from the gap between the two first conveyor chains 12 on the electrode stack conveying system 1. The first lifting mechanism 13 uses an existing lifting structure, such as an electric cylinder, pneumatic cylinder, electric push rod, or elevator, etc., which is not limited here. The lifting end of the first lifting mechanism 13 is configured as two support bars 14. The two support bars 14 are arranged at intervals along the horizontal longitudinal direction. The distance between the two support bars 14 is smaller than the distance between the two first conveying chains 12 on the electrode plate stack conveying system 1. The support bars 14 are arranged at intervals along the horizontal longitudinal direction and extend laterally along the horizontal direction. Under the drive of the first lifting mechanism 13, the two support bars 14 can extend vertically from between the two first conveying chains 12 on the electrode plate stack conveying system 1, and simultaneously lift up multiple stacks of electrode plates 15 placed on the two first conveying chains 12, so as to facilitate the gripping of the three-axis robot arm 3.

[0057] Reference Figure 1 - Figure 4 and Figure 5 - Figure 11Two independent electrode plate stack loading and conveying systems 2 are also provided. The two electrode plate stack loading and conveying systems 2 are arranged at intervals along the horizontal longitudinal direction. Each electrode plate stack loading and conveying system 2 is located outside the electrode plate stack conveying system 1 along the horizontal longitudinal direction. The electrode plate stack loading and conveying system 2 is equipped with a grid plate 9 for loading electrode plate stacks. When the grid plate 9 is full of electrode plate stacks 15, they are transported horizontally by the electrode plate stack loading and conveying system 2. Specifically, the electrode plate stack loading and conveying system 2 includes a second frame 20, a second drive unit 21, and two conveyor chain groups 22. The two conveyor chain groups 22 are arranged side by side at intervals along the horizontal longitudinal direction and are driven on the second frame 20. Each conveyor chain group 22 includes two second conveyor chains 220. The two second conveyor chains 220 are arranged at intervals along the horizontal longitudinal direction and are driven on the second frame 20. The second conveyor chains 220 being driven on the second frame 20 is a conventional and existing structure in mechanical transmission structures, and will not be described in detail here. The second drive unit 21 is mounted on the second frame 20. The second drive unit 21 uses a drive motor to drive the two conveyor chain groups 22 synchronously. Of course, the two conveyor chain groups 22 are used to support the grid plate 9, which is to be loaded with pole plates, on opposite sides along the horizontal longitudinal direction. The grid plate 9 is provided with two pole plate stack placement areas 90. Each pole plate stack placement area 90 is provided with two rows of clearance holes 91 at intervals along the horizontal longitudinal direction. The distance between the two rows of clearance holes 91 on each pole plate stack placement area 90 is less than the width of the pole plate stack 15 in the horizontal longitudinal direction. The distance between the two rows of clearance holes 91 on each pole plate stack placement area 90 is greater than or less than the distance between the two forks 351. Specifically, each row of clearance holes 91 includes multiple clearance holes 91 spaced horizontally, and each clearance hole 91 penetrates the opposite surface of the grid plate 9 vertically; a second lifting mechanism 23 is provided on the second frame 20, and a lifting assembly 24 is provided at the lifting end of the second lifting mechanism 23. The lifting assembly 24 includes two sets of lifting bars 241. Correspondingly, each set of lifting bars 241 includes two rows of lifting bars 241, and each row of lifting bars 241 includes multiple lifting bars 241. The multiple lifting bars 241 correspond one-to-one with the multiple clearance holes 91, and the lifting bars 241 can pass through the clearance holes 91 vertically.

[0058] Reference Figure 1 and Figure 5 - Figure 7The three-axis robot 3 is used to simultaneously load the electrode stacks 15 from two electrode stack conveying systems 1 onto the grid plate 9 of one electrode stack loading and conveying system 2. Specifically, the three-axis robot 3 includes a fixed frame 30, a lateral movement module 31, a longitudinal movement module 32, a lifting module 33, a connecting seat 34, and a fork assembly 35. The fixed frame 30 is longitudinally spanned across the two electrode stack conveying systems 1. The lateral movement module 31 is located on top of the fixed frame 30. The longitudinal movement module 32 is located on the lateral movement module 31 and is used to drive the longitudinal movement module 32 to move horizontally. The lifting module 33 is located on the longitudinal movement module 32 and is used to drive the lifting module 33 to move horizontally. The connecting seat 34 is located on the lifting module 33 and is used to drive the connecting seat 34 to move vertically. The fork assembly 35 is fixed to the connecting seat 34. In summary, the fork assembly 35 can move horizontally or vertically, or move vertically.

[0059] It should be noted that the horizontal movement module 31, the vertical movement module 32, and the lifting module 33 can all be existing linear drive modules, which will not be elaborated here.

[0060] Reference Figure 1 and Figure 3 The fork assembly 35 has two sets, which are arranged at a distance along the horizontal longitudinal direction. The two sets of fork assemblies 35 can move in opposite directions or towards each other along the horizontal longitudinal direction, so that the distance between the two sets of fork assemblies 35 can be changed. In this embodiment, the opposite or opposite movement of the two sets of fork assemblies 35 along the horizontal longitudinal direction can be driven by a bidirectional cylinder; of course, in other embodiments, the opposite or opposite movement of the two sets of fork assemblies 35 along the horizontal longitudinal direction can also be driven by a bidirectional screw mechanism, which is not limited here.

[0061] Reference Figure 1 , Figure 3 and Figure 5 - Figure 7Each fork assembly 35 includes two forks 351, which extend horizontally. The forks 351 are fixed to the connecting seat 34 by an inverted L-shaped member 36. The inverted L-shaped member 36 is integrally formed with the forks 351. The two forks 351 in each fork assembly 35 are used to support the pole plate stack 15 lifted by each first lifting mechanism 13. The two forks 351 are also used to move the pole plate stack 15 they support to the top of the grid plate 9 and place it on the grid plate 9. Specifically, it can be understood that when multiple stacks of electrode plates 15 on the two first conveyor chains 12 of the electrode plate stack conveying system 1 are conveyed to the preset position at the end of the electrode plate stack conveying system 1, the first lifting mechanism 13 drives the support bar 14 to extend vertically from between the two first conveyor chains 12 on the electrode plate stack conveying system 1, thereby simultaneously lifting the multiple stacks of electrode plates 15 located on the two first conveyor chains 12; at this time, the two sets of fork assemblies 35 move in opposite directions, increasing the distance between the two sets of fork assemblies 35 so that each fork assembly 35 faces each electrode plate stack conveying system 1; driven by the lateral movement module 31, the longitudinal movement module 32, and the lifting module 33, two forks 351 in one set of fork assemblies 35 move to above the two first conveyor chains 12 of one electrode plate stack conveying system 1, and two forks 351 in another set of fork assemblies 35 move to above the two first conveyor chains 12 of another electrode plate stack conveying system 1, and one set of fork assemblies 35 moves to above the two first conveyor chains 12 of another electrode plate stack conveying system 1. Two forks 351 of the fork assembly 35 are inserted below a multi-stack pole plate stack 15 lifted by a first lifting mechanism 13, and two forks 351 of another fork assembly 35 are inserted below another multi-stack pole plate stack 15 lifted by a first lifting mechanism 13. Then, the lifting module 33 drives the connecting seat 34 to drive the two fork assemblies 35 to rise synchronously, so that the two forks 351 of each fork assembly 35 move the multi-stack pole plate stack 15 supported by the two support bars 14 on each first lifting mechanism 13 to the two forks 351 of each fork assembly 35, and are supported by the two forks 351 of each fork assembly 35. Then, the two fork assemblies 35 move towards each other in the horizontal longitudinal direction, shortening the distance between the two fork assemblies 35. Then, the two fork assemblies 35 place the multi-stack pole plate stack 15 they each carry on the two pole plate stack placement areas 90 on the grid plate 9 of a pole plate stack loading and conveying system 2.

[0062] This section explains how the fork assembly 35 places its multi-stack pole plate stack 15 in the pole plate stack placement area 90 of the grid plate 9: (Refer to...) Figure 2 and Figure 8 - Figure 11Within a pallet stack placement area 90, two horizontally adjacent lifting bars 241 form a lifting module. The number of lifting modules is the same as the number of pallet stacks 15 carried by the fork assembly 35. That is, within a pallet stack placement area 90, each pallet stack 15 carried by the fork assembly 35 can be placed on each lifting module in the horizontal direction. Since each pole plate stack placement area 90 has two rows of clearance holes 91 spaced along the horizontal longitudinal direction, and the distance between the two rows of clearance holes 91 in each pole plate stack placement area 90 is less than the width of the pole plate stack 15 in the horizontal longitudinal direction, and the distance between the two rows of clearance holes 91 is less than or greater than the distance between the two forks 351, when each fork assembly 35 moves its respective multi-pile pole plate stack 15 above the two pole plate stack placement areas 90, the second lifting mechanism 23 drives the two sets of lifting bars 241 to rise synchronously, so that each lifting bar 241 passes through the clearance holes 91 and extends above the grid plate 9; at this time, the fork assembly 35 is driven to descend, so that each fork assembly 35 can place its respective pole plate stack 15 on the lifting module in each pole plate stack placement area 90. In this way, the pole plate stacks 15 on the two pole plate stack conveying systems 1 can be simultaneously loaded onto the grid plate 9 of one pole plate stack loading and conveying system 2, so that the multi-pile pole plate stacks 15 are arranged in an array on the grid plate 9.

[0063] Reference Figure 2 Two independent transition conveying lifting systems 4 are provided, arranged longitudinally and horizontally. Each transition conveying lifting system 4 includes a lifting unit 40 and a transition conveying device 41. The lifting unit 40 is drivenly connected to the transition conveying device 41. The lifting unit 40 is an existing lifting machine used to drive the transition conveying device 41 to lift. Each transition conveying device 41 extends laterally and can connect with each pole plate stack loading conveying system 2. The transition conveying device 41 is used to receive and convey the grating plate 9 conveyed by the pole plate stack loading conveying system 2. Thus, it can be understood that after the fork assembly 35 loads the pole plate stack 15 onto the grating plate 9, the grating plate 9 filled with the pole plate stack 15 is conveyed to the transition conveying device 41 through the pole plate stack loading conveying system 2, and then conveyed to the curing rack loading system 7 by the transition conveying device 41.

[0064] Reference Figure 1 , Figure 2 and Figure 12The transition conveying device 41 includes a fifth frame 410, a fifth drive unit 411, and two sets of fifth conveying chains 412. The fifth frame 410 is fixed to the lifting end of the lifting unit 40. The two sets of fifth conveying chains 412 are arranged side by side at intervals along the horizontal longitudinal direction and are driven on the fifth frame 410. The fifth drive unit 411 is a servo motor and is fixed on the fifth frame 410 to drive the two sets of fifth conveying chains 412 synchronously. The fifth frame 410 has an active transmission mechanism 42 and a passive transmission mechanism 43 respectively driven at opposite ends. The fifth drive unit 411 is driven and connected to the active transmission mechanism 42. The fifth frame 410 has a first guide sprocket 413 driven at the middle position of opposite sides along the horizontal longitudinal direction. The fifth frame 410 also has a second guide sprocket 414 and a third guide sprocket 415 driven at opposite sides along the horizontal longitudinal direction. The second guide sprocket 414 and the third guide sprocket 415 are located on opposite sides of the first guide sprocket 413 along the horizontal transverse direction. The fifth frame 410 also has a fourth guide sprocket 416 and a fifth guide sprocket 417 driven at opposite sides along the horizontal longitudinal direction. The fourth guide sprocket 416 is located in front of the second guide sprocket 414, and the fifth guide sprocket 417 is located behind the third guide sprocket 415. The fifth conveyor chain 412 is sequentially connected to the active drive mechanism 42, the fifth guide sprocket 417, the second guide sprocket 414, the first guide sprocket 413, the third guide sprocket 415, the fourth guide sprocket 416, the passive drive mechanism 43, and the active drive mechanism 42. The portion of the fifth conveyor chain 412 corresponding to the fourth guide sprocket 416 is above the first guide sprocket 413, the portion corresponding to the first guide sprocket 413 is below the first guide sprocket 413, the portion corresponding to the second guide sprocket 414 is above the second guide sprocket 414, and the portion corresponding to the third guide sprocket 415 is below the third guide sprocket 415. The portion of the fifth conveyor chain 412 corresponding to the fifth guide sprocket 417... Part of it is located above the first guide sprocket 413; the rotation axes of the fourth guide sprocket 416, the fifth guide sprocket 417, the active transmission mechanism 42, and the passive transmission mechanism 43 are located in the same plane. The rotation axis of the first guide sprocket 413 and the rotation axis of the active transmission mechanism 42 are located in the same horizontal plane.

In addition, the distance between the fourth guide sprocket 416 and the first guide sprocket 413 is less than the length of the grid plate 9 in the horizontal direction. Similarly, the distance between the fifth guide sprocket 417 and the first guide sprocket 413 is less than the length of the grid plate 9 in the horizontal direction.In addition, the fifth frame 410 has clearance grooves 418 on its two opposite outer side walls along the horizontal longitudinal direction, corresponding to the positions of the second guide sprocket 414 and the third guide. The clearance grooves 418 are mainly used to prevent the material handling device 62 from placing the grid plate 9 on the two sets of fifth conveyor chains 412.

[0065] Reference Figure 1 , Figure 2 , Figure 13 The curing rack loading system 7 is horizontally arranged at one end of the transition conveyor 41, opposite to the electrode plate stack loading and conveying system 2. The curing rack loading system 7 includes a support frame 70, which is located at the end (rear end) of the transition conveyor 41, and two curing racks 71 are mounted on the support frame 70. That is, the curing rack loading system 7 loads two curing racks 71, each curing rack 71 corresponding to each transition conveyor 41. The curing rack 71 has multiple vertically spaced and interconnected spatial layers 710, which are used to stack the grid plates 9 fully loaded with electrode plate stacks 15.

[0066] Reference Figure 2 , Figure 13 , Figure 19 - Figure 22 In order to smoothly transport the grating plate 9 loaded with electrode plate stacks 15 on the transition conveyor 41 into the space layer 710 on the curing rack 71, the palletizing conveyor lifting system 8 is used to transport the grating plate 9 loaded with electrode plate stacks 15 on the transition conveyor 41 into the space layer 710 on the curing rack 71. Of course, there are two independent palletizing conveyor lifting systems 8, one palletizing conveyor lifting system corresponding to one transition conveyor 41. Specifically, each palletizing conveyor lifting system 8 includes a stacking lifting mechanism 80 and a palletizing conveyor system 81. The width of the palletizing conveyor system 81 in the horizontal longitudinal direction is smaller than the width of the space layer 710 in the horizontal longitudinal direction, and the length of the palletizing conveyor system 81 in the horizontal transverse direction is smaller than the length of the space layer 710 in the horizontal transverse direction. The stacking lifting mechanism 80 is fixed on the support frame 70 of the curing rack loading system 7. The stacking lifting mechanism 80 uses an existing elevator to drive the palletizing conveyor system 81 to move up and down within the multi-layer space layer 710 of the curing rack 71. Of course, the palletizing conveyor system 81 can be connected to the transition conveyor device 41. The palletizing conveyor system 81 is used to transport and place the grating plates 9 delivered by the transition conveyor device 41 into the space layer 710. Specifically, the palletizing conveyor system 81 places each grating plate 9 sequentially into each space layer 710 of the curing rack 71 from top to bottom.

[0067] Reference Figure 2 , Figure 13 , Figure 19 - Figure 22The palletizing and conveying system 81 includes a third frame 810, a third drive unit, and two third conveying chains 811. The stacking and lifting mechanism 80 is fixed on the support frame 70. The lifting end of the stacking and lifting mechanism 80 is drivenly connected to the third frame 810 to drive the third frame 810 to move up and down. The two third conveying chains 811 are drivenly mounted on the third frame 810 and are spaced apart along the horizontal longitudinal direction. The third drive unit is a drive motor and is fixed on the third frame 810 to drive the two third conveying chains 811 to move synchronously along the horizontal transverse direction.

[0068] Reference Figure 2 , Figure 13 , Figure 19 - Figure 22 The multi-layered spatial layers 710 on the curing rack 71 are respectively designated as the first spatial layer, the second spatial layer, and the third spatial layer from top to bottom. When the grid plate 9 loaded with electrode plate stack 15 is transferred from the electrode plate stack loading and conveying system 2 to the transition conveying device 41; if it is necessary to transport and place the grid plate 9 loaded with electrode plate stack 15 in the first spatial layer, the lifting unit 40 drives the transition conveying device 41 to rise to the corresponding first spatial layer, and the third driving unit drives the palletizing conveying system 81 to rise to the first spatial layer. At this time, the palletizing conveying system 81 is located in the first spatial layer and connected to the transition conveying device 41. When the grid plate 9 loaded with electrode plate stack 15 is transferred from the transition conveying device 41 to the palletizing conveying system 81, it is transported into the first spatial layer by the palletizing conveying system 81. After the palletizing conveying system 81 descends, the load can be transported into the first spatial layer. The grating plate 9 of the full electrode plate stack 15 is placed in the first space layer. If it is necessary to transport and place the grating plate 9 of the full electrode plate stack 15 in the second space layer, the lifting unit 40 drives the transition conveying device 41 to rise to the corresponding second space layer, and the third drive unit drives the palletizing conveying system 81 to rise to the second space layer. At this time, the palletizing conveying system 81 is located in the second space layer and is connected to the transition conveying device 41. When the grating plate 9 of the full electrode plate stack 15 is transferred from the transition conveying device 41 to the palletizing conveying system 81, it is transported into the second space layer by the palletizing conveying system 81. After the palletizing conveying system 81 descends, the grating plate 9 of the full electrode plate stack 15 can be placed in the second space layer. In this way, multiple grating plates 9 of the full electrode plate stack 15 can be stacked in the multi-layer space layer 710 on the curing rack 71.

[0069] In summary, the semi-automatic battery plate stacking equipment of the present invention, when in use, involves manually placing the plate stacks 15 onto the plate stack conveying system 1, which then horizontally transports the plate stacks 15. When the plate stacks 15 reach the preset end position of the plate stack conveying system 1, a three-axis robot 3 loads the plate stacks 15 from the plate stack conveying system 1 onto the grid plate 9 of the plate stack loading and conveying system 2. After the grid plate 9 is filled with plate stacks 15 by the three-axis robot 3, the grid plate 9 filled with plate stacks 15 is horizontally transported through the plate stack loading and conveying system 2 and transitions to... The transition conveyor 41 then transports the grating plate 9, which is loaded with electrode plate stacks 15, to the palletizing conveyor 81 on the curing rack loading system 7. When it is necessary to transport and place the grating plate 9, which is loaded with electrode plate stacks 15, into the first spatial layer, the grating plate 9, loaded with electrode plate stacks 15, is transferred from the electrode plate stack loading conveyor 2 to the transition conveyor 41. The transition conveyor 41, driven by the lifting unit 40, rises to the corresponding first spatial layer. At this time, the palletizing conveyor 81, driven by the stacking lifting mechanism 80, is also in the first spatial layer, so that the grating plate 9, loaded with electrode plate stacks 15, is transferred from the transition conveyor 41 to the palletizing conveyor 81 on the curing rack loading system 7. Driven by the third drive unit, the two third conveyor chains 811 of the palletizing conveyor system 81 transport the grid plate 9 loaded with electrode plate stacks 15 into the first spatial layer, where it is supported. When it is necessary to transport and place the grid plate 9 loaded with electrode plate stacks 15 into the second spatial layer, the grid plate 9 loaded with electrode plate stacks 15 transitions from the electrode plate stack loading conveyor system 2 to the transition conveyor device 41. The transition conveyor device 41 rises to the corresponding second spatial layer under the drive of the lifting unit 40. At this time, the palletizing conveyor system 81 is stacking and lifting... Driven by the lowering mechanism 80, the grating plate 9, which is full of electrode plate stacks 15, is also located in the second space layer. This allows the grating plate 9, which is full of electrode plate stacks 15, to be transferred from the transition conveying device 41 to the two third conveying chains 811 of the palletizing conveying system 81. Driven by the third driving unit, the two third conveying chains 811 of the palletizing conveying system 81 transport the grating plate 9, which is full of electrode plate stacks 15, into the second space layer for support. By doing so, multiple grating plates 9 carrying electrode plate stacks 15 can be automatically stacked in sequence in the multi-layer space layer 710 on the curing rack 71, thereby improving the efficiency of placing the electrode plate stacks 15 on the curing rack 71.

[0070] Reference Figure 1 - Figure 3 , Figure 13The grating plate feeding device 5 is arranged horizontally along the outer side of a transition conveyor 41. The grating plate feeding device 5 is used to transport the grating plate 9 to be loaded into the electrode stack along the horizontal longitudinal direction. In addition, the grating plate picking system 6 is arranged between the two transition conveyors 41. The grating plate picking system 6 is used to place the grating plate 9 to be loaded into the electrode stack conveyor 41 transported by the grating plate feeding device 5 onto one of the two transition conveyors 41. Each transition conveyor 41 is also used to transport the grating plate 9 to be loaded into the electrode stack loading conveyor system 2. Thus, the present invention can automatically transport the grating plate 9 to be loaded into the electrode stack loading conveyor system 2 onto the two second conveyor chains. The two transition conveying devices 41 can operate alternately. For example, when the grating material handling system 6 places the grating plate 9, which is being loaded onto the electrode stack by the grating plate feeding device 5, onto the left transition conveying device 41, the left transition conveying device 41 transports the grating plate 9 to the front end of the left transition conveying device 41. When the grating plate 9 on the left transition conveying device 41 is fully loaded with the electrode stack 15 and is being conveyed into the left palletizing conveying system 81, the grating material handling system 6 places the grating plate 9, which is being loaded onto the electrode stack by the feeding device 5, onto the right transition conveying device 41, and the right transition conveying device 41 transports it to the right transition conveying system 81. The front end of the transition conveyor 41 is reserved; when the grating plate picking system 6 places the grating plate 9 to be loaded onto the right-side transition conveyor 41 by the grating plate feeding device 5, the right-side transition conveyor 41 transports the grating plate 9 to be loaded onto the right-side transition conveyor 41 to the front end of the right-side transition conveyor 41. When the grating plate 9 on the right-side transition conveyor 41 is fully loaded with the electrode plate stack 15 and is transported into the right-side palletizing conveyor system 81, at this time the grating plate picking system 6 places the grating plate 9 to be loaded onto the right-side transition conveyor 41 by the feeding device, and the right-side transition conveyor 41 transports it to the front end of the right-side transition conveyor 41 for reserve.

[0071] Reference Figure 13 and Figure 14 The grating loading device 5 includes a fourth frame 50, a fourth drive unit 51, and two conveyor belts 52. The two conveyor belts 52 are driven on the fourth frame 50 and drive horizontally. The fourth drive unit 51 is a drive motor, fixed on the fourth frame 50, and driven by the conveyor belts 52 to drive the two conveyor belts 52 synchronously. Therefore, when the grating 9 to be loaded onto the electrode stack is manually placed on the two conveyor belts 52, it can be transported horizontally towards the transition conveyor device 41 under the drive of the fourth drive unit 51, allowing the grating loading system 6 to place the grating 9 to be loaded onto one of the two transition conveyor devices 41.

[0072] Based on the above structure, referring to Figure 2 , Figure 13 and Figure 18 Each transition conveying device 41 is provided with a grating storage rack 53 on its outer side along the horizontal longitudinal direction; the grating storage rack 53 has multiple storage layers 530 arranged vertically at intervals. Specifically, on one side of the grating loading device 5, the lowest storage layer 530 on the grating storage rack 53 is located above the grating loading device 5, and the storage layer 530 is used to store the grating plates 9 to be loaded into the electrode stack. Of course, the grating material handling system 6 is also used to store the electrode stack 15 to be loaded conveyed by the grating loading device 5 in the storage layer 530 of each grating storage rack 53. Therefore, the present invention also has the function of storing the grating plates 9 to be loaded into the electrode stack.

[0073] Reference Figure 13 , Figure 15 - Figure 18 The grating material handling system 6 includes a mounting frame 60, a lifting device 61, and a material handling device 62. The mounting frame 60 is located between two transition conveying devices 41. The lifting device 61 is mounted on the mounting frame 60 and is used to drive the material handling device 62 to lift. The material handling device 62 includes a moving mechanism 620 and two support plates 621. The support plates 621 are positioned vertically corresponding to the clearance groove 418, and their vertical projections fall within the clearance groove 418. The moving mechanism 620 is connected to the lifting device 61 so that the moving mechanism 620... The lifting device 61 and the moving mechanism 620 are capable of lifting and lowering. Two support plates 621 are horizontally spaced on the moving mechanism 620, with the distance between the two support plates 621 being less than the length of the grid plate 9 in the horizontal direction. The moving mechanism 620 drives the two support plates 621 to move in the horizontal direction, so that the two support plates 621 can move to the lower end of the grid plate loading device 5 to lift the grid plate 9 of the electrode stack to be loaded on the grid plate loading device 5, and store the lifted grid plate 9 in the storage layer 530 on the grid plate storage rack 53. Thus, after the two support plates 621 lift the grid plate 9 of the electrode stack to be loaded, under the drive of the lifting device 61 and the moving mechanism 620, the two support plates 621 insert the grid plate 9 of the electrode stack to be loaded into the storage layer 530, which is similar to a drawer opening, on the grid plate storage rack 53 near the grid plate loading device 5.

[0074] Reference Figure 2 , Figure 3 , Figure 8 , Figure 12 , Figure 13 and Figure 15 - Figure 17When the material handling device 62 needs to place the grating plate 9 of the electrode plate stack to be loaded onto the two sets of fifth conveyor chains 412, and the fifth conveyor chains 412 transport it to the electrode plate stack loading and conveying system 2, the support plate 621 lifts the grating plate 9 of the electrode plate stack to be loaded. Under the drive of the lifting device 61 and the moving mechanism 620, the support plate 621 places the grating plate 9 of the electrode plate stack to be loaded onto the two sets of fifth conveyor chains 412 from the position of the clearance groove 418, thereby realizing the purpose of the grating plate material handling system 6 to place the grating plate 9 of the electrode plate stack to be loaded onto the transition conveying device 41.

[0075] It should be noted that the lifting device 61 uses an existing lifting structure, such as a screw lifting mechanism or a lifting platform, and the moving mechanism 620 also uses an existing structure, such as a linear module, which will not be elaborated here.

[0076] Additionally, refer to Figure 15 - Figure 17 The grating material handling system 6 also includes a rotating mechanism 63, which is mounted on the lifting device 61. The rotating mechanism 63 drives the material handling device 62 to rotate. Since there is only one grating material loading device 5, while there are two grating material storage racks 53, when the two support plates 621 need to insert the grating plate 9 to be loaded into the storage layer 530 (similar to a drawer opening) on ​​the grating material storage rack 53 facing away from the grating material loading device 5, the rotating mechanism 63 drives the material handling device 62 to rotate 180°. This allows the two supports to be inserted into the storage layer 530 (similar to a drawer opening) on ​​the grating material storage rack 53 facing away from the grating material loading device 5, thereby inserting the grating plate 9 to be loaded into the storage layer 530 on the grating material storage rack 53 facing away from the grating material loading device 5.

[0077] It should be noted that the rotating mechanism 63 also uses an existing structure, which will not be described in detail here.

[0078] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
