Technical Field

[0001] The invention relates to the technical field of battery manufacturing, and in particular to a semi-automatic battery plate stacking device. Background Art

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

[0003] At present, in the prior art, the stack of plates usually needs to be placed manually on the grid plate. When the grid plate is filled with the stack of plates, the grid plate filled with the stack of plates needs to be placed manually on the curing rack. However, manually placing the stack of plates on the grid plate is extremely labor-intensive. In addition, the curing rack has multiple layers of space for the grid plates to be stacked. When the grid plates carrying the stack of plates are manually placed on the curing rack to fill the space, it is also extremely labor-intensive and inefficient. Summary of the invention

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0051] Reference Figure 1 - Fig. 22 The present invention provides a semi-automatic battery plate stacking equipment, including a plate stack conveying system 1, a plate stack loading and conveying system 2, a three-axis manipulator 3, a transition conveying and lifting system 4, a grid plate feeding device 5, a grid plate taking system 6, a curing rack loading system 7 and a stacking conveying and lifting system 8.

[0052] Reference Figure 1 - Figure 4 , there are two plate stack conveying systems 1, the two plate stack conveying systems 1 are independently arranged, the two plate stack conveying systems 1 are arranged side by side and spaced in the horizontal longitudinal direction, and the plate stack conveying systems 1 are used to convey the plate stack 15 to move horizontally. Specifically, each plate stack conveying system 1 includes a first frame 10, a first drive unit 11 and at least two first conveying chains 12, the two first conveying chains 12 are arranged side by side and spaced in the horizontal longitudinal direction and are driven on the first frame 10, the first drive unit 11 uses a servo motor, the first drive unit 11 is fixed on the first frame 10, the first drive unit 11 is used to drive the two first conveying chains 12 to drive synchronously, and the two first conveying chains 12 are respectively used to support the plate stack 15 on the opposite sides in the horizontal longitudinal direction. That is to say, it can be understood that the opposite sides of the plate stack 15 are manually placed on the two first conveying chains 12, and under the drive of the first drive unit 11, the plate stack 15 is transported by the two first conveying chains 12 in the horizontal transverse direction.

[0053] Among them, the first drive unit 11 can control the intermittent movement or continuous movement of the two first conveying chains 12. A person stands at the front working station of the plate stack conveying system 1. When the person places the first stack of plate stacks 15 on the two first conveying chains 12 at the working station, the first drive unit 11 controls the two first conveying chains 12 to move backward synchronously for a short distance and then stop. Then the person continues to place the second stack of plate stacks 15 on the two first conveying chains 12 at the original working station. After the second stack of plate stacks 15 is placed, the first drive unit 11 controls the two first conveying chains 12 to move backward synchronously for a short distance and then stop. Then the person continues to place the third stack of plate stacks 15 on the two first conveying chains 12 at the original working station, and the cycle continues.

[0054] After manually placing a plurality of plate stacks 15 (such as 7 plate stacks 15) horizontally and transversely spaced on the two first conveyor chains 12, the first drive unit 11 controls the two first conveyor chains 12 to continuously move, and conveys the plurality of plate stacks 15 on the two first conveyor chains 12 to the preset end position of the plate stack conveying system 1, and then the three-axis manipulator 3 synchronously places the plurality of plate stacks 15 on the two plate stack conveying systems 1 on the grid plate 9 of a plate stack loading conveying system 2. It should be noted that the transmission arrangement of the first conveyor chain 12 on the first frame 10 is a conventional and existing structure in the mechanical transmission structure, and will not be described in detail here.

[0055] Exemplarily, the first conveyor chain 12 has a sensor for detecting whether a stack of plates 15 is placed. The sensor is electrically connected to the control system of the semi-automatic battery plate stacking equipment. The control system can select an existing PLC control system, which is not described here. For example, when the sensor detects that 7 stacks of plates 15 are placed on the first conveyor chain 12, the first drive unit 11 controls the two first conveyor chains 12 to move continuously. Among them, the sensor can be a weighing sensor. Since the weight of each stack of plates 15 is the same, by determining the weight of the stack of plates 15 on the first conveyor chain 12, it can be determined how many stacks of plates 15 are placed on the first conveyor chain 12. In another exemplary embodiment, it is also possible to determine how many stacks of plates 15 are placed on the first conveyor chain 12 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 three-axis manipulator 3 to transfer the pole plate stack 15 on the first conveying chain 12 to the grid plate 9 on a pole plate stack loading conveying system 2, a first lifting mechanism 13 is also provided at the preset position at the end of the first frame 10 corresponding to the pole plate stack conveying system 1.

The spacing between the two support bars 14 is smaller than the spacing between the two first conveying chains 12 on the pole plate stack conveying system 1, and the support bars 14 are arranged at intervals along the horizontal longitudinal direction. The support bars 14 extend horizontally. 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 pole plate stack conveying system 1, and simultaneously lift up multiple pole plate stacks 15 placed on the two first conveying chains 12, so as to facilitate the grasping of the three-axis manipulator 3.

Specifically, it can be understood that when the multiple stacks of pole plates 15 on the two first conveying chains 12 of the pole plate stack conveying system 1 are conveyed to the preset position at the end of the pole plate stack conveying system 1, the first lifting mechanism 13 drives the support bar 14 to extend vertically from between the two first conveying chains 12 on the pole plate stack conveying system 1, thereby lifting the multiple stacks of pole plates 15 on the two first conveying chains 12 at the same time; at this time, the two groups of fork assemblies 35 move in opposite directions to increase the distance between the two groups of fork assemblies 35 so that each fork assembly 35 is facing each pole plate stack conveying system 1; under the drive of the lateral moving module 31, the longitudinal moving module 32, and the lifting module 33, the two forks 351 in one group of fork assemblies 35 move to the top of the two first conveying chains 12 of one pole plate stack conveying system 1, and the two forks 351 in the other group of fork assemblies 35 move to the top of the two first conveying chains 12 of another pole plate stack conveying system 1, and a group The two forks 351 of the fork assembly 35 are inserted under the multi-pile stack 15 of the pole plates lifted by the first lifting mechanism 13, and the two forks 351 of the other group of fork assemblies 35 are inserted under the multi-pile stack 15 of the pole plates lifted by the other first lifting mechanism 13; then, the lifting module 33 drives the connecting seat 34 to drive the two groups of fork assemblies 35 to rise synchronously, so that the two forks 351 in each group of fork assemblies 35 move the multi-pile stacks 15 supported by the two support bars 14 on each first lifting mechanism 13 to the two forks 351 in each group of fork assemblies 35, and are supported by the two forks 351 in each group of fork assemblies 35; then, the two groups of fork assemblies 35 move toward each other in the horizontal longitudinal direction to shorten the distance between the two groups of fork assemblies 35; then, the two groups of fork assemblies 35 place the multi-pile stacks 15 they 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] Here, it is explained how the fork assembly 35 places the stacks of plate stacks 15 it carries on the plate stack placement area 90 of the grid plate 9: Figure 2 and Figure 8 - Fig.11In one plate stack placement area 90, two jacking bars 241 adjacent in the horizontal longitudinal direction form a jacking module, and the number of jacking modules is the same as the number of plate stacks 15 carried by the fork assembly 35. That is, in one plate stack placement area 90, each plate stack 15 carried by the fork assembly 35 can be placed on each jacking module in the horizontal longitudinal direction. Since each plate stack placement area 90 is provided with two rows of avoidance holes 91 spaced apart in the horizontal longitudinal direction, the spacing between the two rows of avoidance holes 91 on each plate stack placement area 90 is smaller than the width of the plate stack 15 in the horizontal longitudinal direction, and the spacing between the two rows of avoidance holes 91 is smaller than or larger than the spacing between the two forks 351, when each fork assembly 35 moves the multiple plate stacks 15 carried by each of them to the top of the two plate stack placement areas 90, the second lifting mechanism 23 drives the two groups of lifting bars 241 to rise synchronously, so that each lifting bar 241 passes through each avoidance hole 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 the plate stacks 15 carried by each of them on the lifting modules on each plate stack placement area 90. In this way, the plate stacks 15 on the two plate stack conveying systems 1 can be simultaneously loaded on the grid plate 9 of one plate stack loading and conveying system 2, so that the multiple plate stacks 15 are placed on the grid plate 9 in an array.

[0063] Reference Figure 2 , there are two transition conveying and lifting systems 4 which are independent of each other.

The transition conveying device 41 is used to receive and convey the grid plate 9 delivered by the plate stack loading and conveying system 2. It can be understood that when the fork assembly 35 loads the plate stack 15 on the grid plate 9, the grid plate 9 loaded with the plate stack 15 is transported to the transition conveying device 41 through the plate stack loading and conveying system 2, and then transported to the curing rack loading system 7 by the transition conveying device 41.

The avoidance grooves 418 are mainly used to prevent the material taking device 62 from placing the grid plate 9 on the two sets of fifth conveying chains 412.

[0065] Reference Figure 1 , Figure 2 , Fig.13 , the curing rack loading system 7 is horizontally arranged at one end of the transition conveying device 41 facing away from the plate stack loading 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 conveying device 41, and two curing racks 71 are arranged on the support frame 70. That is, the curing rack loading system 7 is loaded with two curing racks 71, each curing rack 71 corresponds to each transition conveying device 41, and the curing rack 71 has multiple space layers 710 arranged vertically at intervals and interpenetrating with each other, and the space layers 710 are used to stack the grid plates 9 loaded with the plate stacks 15.

[0066] Reference Figure 2 , Fig.13 , Fig.19 - Fig. 22 In order to smoothly transport the grid plate 9 loaded with the plate stack 15 on the transition conveyor 41 into the space layer 710 on the curing rack 71, the grid plate 9 loaded with the plate stack 15 on the transition conveyor 41 is transported into the space layer 710 on the curing rack 71 by the stacking conveying lifting system 8. Of course, the stacking conveying lifting system 8 is also provided with two independent stacking conveying lifting systems, one stacking conveying lifting system corresponding to one transition conveyor 41. Specifically, each stacking conveying lifting system 8 includes a stacking lifting mechanism 80 and a stacking conveying system 81, the width of the stacking conveying 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 stacking conveying 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, and the stacking lifting mechanism 80 uses an existing elevator to drive the stacking conveying system 81 to rise and fall in the multi-layer space layer 710 of the curing rack 71. Of course, the stacking conveying system 81 can be connected with the transition conveying device 41, and the stacking conveying system 81 is used to convey and place the grid plates 9 conveyed by the transition conveying device 41 in the space layer 710. The stacking conveying system 81 places each grid plate 9 in each space layer 710 of the curing rack 71 from top to bottom.

[0067] Reference Figure 2 , Fig.13 , Fig.19 - Fig. 22The stacking conveying system 81 includes a third frame 810, a third driving unit and two third conveying chains 811. The stacking lifting mechanism 80 is fixed on the supporting frame 70. The lifting end of the stacking lifting mechanism 80 is drivingly connected to the third frame 810 for driving the third frame 810 to lift and lower. The two third conveying chains 811 are transmission-arranged on the third frame 810. The two third conveying chains 811 are arranged at intervals along the horizontal longitudinal direction. The third driving unit is a driving motor, and the third driving unit is fixed on the third frame 810 for driving the two third conveying chains 811 to synchronously transmit along the horizontal transverse direction.

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

[0069] In summary, when the semi-automatic battery plate stacking device of the present invention is used, the plate stack 15 is manually placed on the plate stack conveying system 1, and the plate stack 15 is conveyed horizontally by the plate stack conveying system 1; when the plate stack 15 is conveyed to the end preset position of the plate stack conveying system 1, the plate stack 15 on the plate stack conveying system 1 is loaded on the grid plate 9 of the plate stack loading and conveying system 2 by the three-axis manipulator 3; when the grid plate 9 is loaded with the plate stack 15 by the three-axis manipulator 3, the grid plate 9 loaded with the plate stack 15 is conveyed horizontally by the plate stack loading and conveying system 2 and transitioned to The transition conveyor 41 is then transported by the transition conveyor 41 to the stacking conveyor system 81 on the curing rack loading system 7; when the grid plate 9 loaded with the plate stack 15 needs to be transported and placed in the first space layer, the grid plate 9 loaded with the plate stack 15 is transferred from the plate stack loading conveyor system 2 to the transition conveyor 41, and the transition conveyor 41 is driven by the lifting unit 40 to the corresponding first space layer. At this time, the stacking conveyor system 81 is also in the first space layer under the drive of the stacking lifting mechanism 80, so that the grid plate 9 loaded with the plate stack 15 is transferred from the transition conveyor 41 to the first space layer. On the two third conveyor chains 811 of the stacking conveying system 81, driven by the third driving unit, the two third conveyor chains 811 of the stacking conveying system 81 convey the grid plate 9 loaded with the plate stack 15 into the first space layer and supported by the first space layer; when it is necessary to convey the grid plate 9 loaded with the plate stack 15 and place it in the second space layer, the grid plate 9 loaded with the plate stack 15 is transferred from the plate stack loading conveying system 2 to the transition conveying device 41, and the transition conveying device 41 rises to the corresponding second space layer under the drive of the lifting unit 40. At this time, the stacking conveying system 81 is in the stacking lifting layer. Driven by the lowering mechanism 80, it is also in the second space layer, so that the grid plate 9 loaded with the electrode plate stack 15 is transitioned from the transition conveying device 41 to the two third conveying chains 811 of the stacking conveying system 81. Driven by the third driving unit, the two third conveying chains 811 of the stacking conveying system 81 convey the grid plate 9 loaded with the electrode plate stack 15 into the second space layer and supported by the second space layer. By analogy, multiple grid plates 9 carrying the electrode plate stack 15 can be automatically stacked in turn in the multi-layer space layer 710 on the curing rack 71, thereby improving the efficiency of placing the electrode plate stack 15 on the curing rack 71.

[0070] Reference Figure 1 - Figure 3 , Fig.13, the grid plate loading device 5 is arranged on the outside of a transition conveying device 41 along the horizontal longitudinal direction, and the grid plate loading device 5 is used to transport the grid plates 9 to be loaded with the plate stacks along the horizontal longitudinal direction; in addition, the grid plate taking system 6 is arranged between the two transition conveying devices 41, and the grid plate taking system 6 is used to place the grid plates 9 to be loaded with the plate stacks transported by the grid plate loading device 5 on one of the two transition conveying devices 41, and each transition conveying device 41 is also used to transport the grid plates 9 to be loaded with the plate stacks into each plate stack loading conveying system 2. It can be seen from this that the present invention can automatically transport the grid plates 9 to be loaded with the plate stacks into the two second conveying chains of the plate stack loading conveying system 2. Among them, the two transition conveying devices 41 can work alternately. For example, when the grid plate taking system 6 places the grid plate 9 of the stack of plates to be loaded transported by the grid plate loading device 5 on the transition conveying device 41 on the left, the grid plate 9 of the stack of plates to be loaded is transported to the front end of the transition conveying device 41 on the left by the transition conveying device 41 on the left. When the grid plate 9 on the transition conveying device 41 on the left is fully loaded with the stack of plates 15 and transported into the stacking conveying system 81 on the left, the grid plate taking system 6 places the grid plate 9 of the stack of plates to be loaded transported by the loading device on the transition conveying device 41 on the right, and is transported to the right transition conveying device 41 by the transition conveying device 41 on the right. The front end of the transition conveyor 41 is kept in reserve; when the grid plate picking system 6 places the grid plate 9 of the stack of pole plates to be loaded transported by the grid plate loading device 5 on the transition conveyor 41 on the right, the grid plate 9 of the stack of pole plates to be loaded is transported to the front end of the transition conveyor 41 on the right by the transition conveyor 41 on the right, and when the grid plate 9 on the transition conveyor 41 on the right is fully loaded with the stack of pole plates 15 and transported into the stacking conveyor system 81 on the right, at this time, the grid plate picking system 6 places the grid plate 9 of the stack of pole plates to be loaded transported by the loading device on the transition conveyor 41 on the right, and is transported by the transition conveyor 41 on the right to the front end of the transition conveyor 41 on the right for reserve.

[0071] Reference Fig.13 and Fig.14 The grid plate feeding device 5 includes a fourth frame 50, a fourth driving unit 51 and two conveyor belts 52. The two conveyor belts 52 are arranged on the fourth frame 50. The conveyor belts 52 are driven in the horizontal longitudinal direction. The fourth driving unit 51 uses a driving motor. The fourth driving unit 51 is fixed on the fourth frame 50 and is connected to the conveyor belts 52 for driving the two conveyor belts 52 to drive synchronously. It can be seen that the grid plate 9 to be loaded with the plate stack is manually placed on the two conveyor belts 52. Under the drive of the fourth driving unit 51, the grid plate 9 can be transported in the horizontal longitudinal direction toward the transition conveyor device 41, so that the grid plate taking system 6 can place the grid plate 9 to be loaded with the plate stack on one of the two transition conveyor devices 41.

[0072] Based on the above structure, refer to Figure 2 , Fig.13 and Fig.18 , each transition conveying device 41 is provided with a grid plate storage rack 53 on the outer side along the horizontal longitudinal direction; the grid plate storage rack 53 has multiple storage layers 530 arranged at intervals along the vertical direction. Among them, on one side of the grid plate feeding device 5, the lowest storage layer 530 on the grid plate storage rack 53 is located above the grid plate feeding device 5, and the storage layer 530 is used to store the grid plates 9 to be loaded with the plate stacks. Of course, the grid plate taking system 6 is also used to store the plate stacks 15 to be loaded conveyed by the grid plate feeding device 5 in the storage layers 530 on each grid plate storage rack 53. It can be seen from this that the present invention also has the function of storing the grid plates 9 to be loaded with the plate stacks.

[0073] Reference Fig.13 , Fig.15 - Fig.18 The grid plate reclaiming system 6 includes a mounting frame 60, a lifting device 61 and a reclaiming device 62. The mounting frame 60 is arranged between the two transition conveying devices 41. The lifting device 61 is arranged on the mounting frame 60 to drive the reclaiming device 62 to rise and fall. The reclaiming device 62 includes a moving mechanism 620 and two support plates 621. The support plates 621 correspond to the positions of the avoidance groove 418 in the vertical direction. The projection of the support plates 621 in the vertical direction falls in the avoidance groove 418. The moving mechanism 620 is connected to the lifting device 61 so that the moving mechanism 62 0 can be lifted and lowered, two support plates 621 are arranged on the moving mechanism 620 at intervals along the horizontal lateral direction, and the spacing between the two support plates 621 is smaller than the length of the grid plate 9 in the horizontal lateral direction. The moving mechanism 620 is used to drive the two support plates 621 to move in the horizontal longitudinal direction, so that the two support plates 621 can move to the lower end of the grid plate feeding device 5 to lift the grid plate 9 of the stack of plates to be loaded on the grid plate feeding device 5, and store the lifted grid plate 9 in the storage layer 530 on the grid plate storage rack 53. It can be seen that after the two support plates 621 lift the grid plate 9 of the stack of plates 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 stack of plates to be loaded into the storage layer 530 similar to the drawer opening on the grid plate storage rack 53 close to the grid plate feeding device 5 for storage.

[0074] Reference Figure 2 , Figure 3 , Figure 8 , Fig.12 , Fig.13 and Fig.15 - Fig.17, when the material picking device 62 is needed to place the grid plates 9 of the stack of pole plates to be loaded on the two groups of fifth conveying chains 412, and the fifth conveying chains 412 are used to transport the grid plates 9 to the stack of pole plates for loading and conveying to the stack of pole plates 2, the support plate 621 lifts the grid plates 9 of the stack of pole plates to be loaded, and then, driven by the lifting device 61 and the moving mechanism 620, the support plate 621 places the grid plates 9 of the stack of pole plates to be loaded on the two groups of fifth conveying chains 412 from the position of the avoidance groove 418, thereby achieving the purpose of the grid plate material picking system 6 placing the grid plates 9 of the stack of pole plates to be loaded on 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 an elevator, and the moving mechanism 620 also uses an existing structure, such as a linear module, which will not be described in detail here.

[0076] In addition, refer to Fig.15 - Fig.17 The grid plate taking system 6 also includes a rotating mechanism 63, which is arranged on the lifting device 61 and is used to drive the taking device 62 to rotate. Since there is only one grid plate feeding device 5 and two grid plate storage racks 53 are provided, when the two support plates 621 need to insert the grid plates 9 to be loaded with the plate stack into the storage layer 530 similar to the drawer opening on the grid plate storage rack 53 facing away from the grid plate feeding device 5 for storage, it is necessary to drive the taking device 62 to rotate 180° through the rotating mechanism 63, so that the two supports can be inserted into the storage layer 530 similar to the drawer opening on the grid plate storage rack 53 facing away from the grid plate feeding device 5, so that the grid plates 9 to be loaded with the plate stack are inserted into the storage layer 530 on the grid plate storage rack 53 facing away from the grid plate feeding device 5 for storage.

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