DETAILED DESCRIPTION

[0034] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0035] like Figures 1 to 8 As shown, the present invention provides a battery stacking platform, which includes a base 1, a clamping drive device 2 arranged on the base 1, a stacking table device 3 movably arranged on the base 1 and capable of placing battery pole pieces, and a pressure claw assembly 6 movably arranged on the base 1, the clamping drive device 2 includes a first displacement mechanism 4 and a second displacement mechanism 5, the second displacement mechanism 5 includes a second driver 51 arranged on the base 1 and a beam 52 connected to the output end of the second driver 51; the first displacement mechanism 4 includes a sliding seat 42 slidably connected to the beam 52 and a first driver 41 arranged on the beam 52, the output end of the first driver 41 is connected to the sliding seat 42, and the pressure claw assembly 6 is connected to the sliding seat 42; the first driver 41 and the second driver 51 cooperate to drive the pressure claw assembly 6 to clamp or loosen the battery pole pieces on the stacking table device 3.

[0036] Specifically, the clamping drive device 2 also includes a controller that is respectively connected to the first driver 41 and the second driver 51, and the controller can be a PLC controller or a motion controller; the second driver 51 is used to drive the crossbeam 52, the first displacement mechanism 4 and the pressure claw assembly 6 to reciprocate in the vertical direction; the first driver 41 is used to drive the sliding seat 42 and the pressure claw assembly 6 to slide back and forth in the horizontal direction relative to the crossbeam 52; the number of the first displacement mechanism 4 and the pressure claw assembly 6 is set to two, and the two first displacement mechanisms 4 are respectively arranged at the two ends of the crossbeam 52, and the two pressure claw assemblies 6 are movable and symmetrically arranged on both sides of the stacking table device 3. During the stacking process of the battery pole pieces, when the battery pole pieces and diaphragms placed on the stacking table device 3 need to be compressed, this can be achieved through the electronic cam curve instructions of the controller, that is, the controller coordinates the first driver 41 and the second driver 51 to synchronously or separately drive the pressure claw assembly 6 to move, thereby realizing the linear or curved movement of the pressure claw assembly 6, and then regularly compressing the battery pole pieces. Figure 4 As shown, when the pressure claw assembly 6 is in the starting position, the pressure claw assembly 6 is pressed on the battery electrode. Figure 4The second driver 51 drives the pressure claw assembly 6 to move upward, thereby releasing the battery electrode, and then drives the pressure claw assembly 6 to move outward in the direction away from the stacking table device 3 through the first driver 41. The second driver 51 and the first driver 41 simultaneously drive the pressure claw assembly 6 upward and move in a curve in the direction away from the stacking table device 3. When the pressure claw assembly 6 moves outward in the direction away from the stacking table device 3 to a preset position, it is convenient to continue to stack the diaphragm and / or the battery electrode on the compressed battery electrode. After stacking, adjust the stacking table device 3. The height in the vertical direction ensures that the height of the topmost battery electrode stacked on the lamination table device 3 remains unchanged in the vertical direction; the second driver 51 and the first driver 41 are then used to simultaneously drive the pressure claw assembly 6 to move upward and in a curved direction close to the battery electrode. When the pressure claw assembly 6 moves upward to a suitable position, the second driver 51 stops moving. When the pressure claw assembly 6 moves to the top of the battery electrode, the second driver 51 drives the pressure claw assembly 6 to press downward on the battery electrode. At this time, the pressure claw assembly 6 returns to the starting position and repeats the above action, thereby achieving the compression and lamination of the battery electrode. The present invention can control the second driver 51 and the first driver 41 to drive the pressure claw assembly 6 to move in a straight line or in a curved line through the electronic cam curve instruction of the controller, and the second driver 51 and the first driver 41 have low power loss, fast moving speed and high sensitivity, low noise generated during operation, and high compression and transmission efficiency of the pressure claw assembly 6. The crossbeam 52 can synchronously drive the first displacement mechanisms 4 and the pressure claw assemblies 6 on the left and right sides to move synchronously, improving the synchronization of the pressure claw assemblies 6 when pressing the battery electrode sheets, improving the quality of the compression of the battery electrode sheets, and simplifying the structure of the pressure claw assemblies 6 by eliminating the need for a motion source. Both the second driver 51 and the first driver 41 can be linear motors.

[0037] Furthermore, the second driver 51 includes a first stator 53 connected to the base 1 and a first mover 54 and a first sliding member 55 respectively connected to the crossbeam 52 . The first sliding member 55 is slidably connected to the first stator 53 .

[0038] Specifically, the number of the first sliding members 55 is set to two, and the two first sliding members 55 are respectively arranged on both sides of the first stator 53. The first sliding member 55 is in a 7-shape, which increases the contact area between the first sliding member 55 and the beam 52, and improves the stability of the beam 52 and the first sliding member 55 during movement; the second displacement mechanism 5 also includes a first grating scale 57 arranged on the first sliding member 55 and a first reading head 56 for reading the value of the first grating scale 57, the first reading head 56 is connected to the first stator 53; the first reading head 56 is electrically connected to the controller. During actual use, the second driver 51 is started, and the first mover 54, the beam 52, the first sliding member 55 and the first displacement mechanism 4 reciprocate in the vertical direction relative to the first stator 53. The first sliding member 55 slides with the first stator 53 to guide and limit the movement of the beam 52, thereby improving the stability and accuracy of the second driver 51 in driving the pressure claw assembly 6 to move in the vertical direction; the first grating scale 57 is set on the first sliding member 55, and the first sliding member 55 drives the first grating scale 57 to reciprocate in the vertical direction relative to the first stator 53, and the first reading head 56 reads the numerical changes of the first grating scale 57 and sends the read numerical values ​​to the controller. After receiving the numerical values ​​sent by the first reading head 56, the controller analyzes and judges, thereby controlling the output frequency of the second driver 51 and accurately controlling the motion trajectory of the pressure claw assembly 6.

[0039] Furthermore, the second displacement mechanism 5 further includes a first sensing switch 58 provided on the first stator 53 and a first sensing piece 59 provided on the first sliding member 55 . The first sensing switch 58 is used to sense the first sensing piece 59 and send out a sensing signal.

[0040] Specifically, the first sensing switch 58 is electrically connected to the controller and is used to sense the first sensing plate 59 and send a sensing signal to the controller. During actual use, the first sliding member 55 drives the first sensing plate 59 to move up and down relative to the first stator 53. When the first sensing switch 58 senses the first sensing plate 59 and sends a sensing signal to the controller, the controller receives the sensing signal and controls the second actuator 51 to stop or reverse direction, further improving the accuracy of the pressure jaw assembly 6 during operation.

[0041] Furthermore, the first driver 41 includes a second stator 43 connected to the beam 52, a second mover 44 connected to the sliding seat 42, and a second sliding member 45 arranged on the sliding seat 42 and slidingly connected to the beam 52; the number of the second sliding members 45 is two, and the two second sliding members 45 are respectively arranged on both sides of the sliding seat 42, and the inner side walls of the two second sliding members 45, the bottom wall of the sliding seat 42 and the top wall of the beam 52 form an accommodating space, and the second stator 43 and the second mover 44 are both arranged in the accommodating space, and the two sides of the bottom end of the second sliding member 45 are respectively slidably connected to the beam 52.

[0042] Specifically, the first displacement mechanism 4 also includes a second grating scale 47 connected to the second sliding member 45 and a second reading head 46 connected to the beam 52. The second reading head 46 is used to read the value of the second grating scale 47. The second reading head 46 and the second grating scale 47 are both arranged in the accommodating space. During actual use, the first driver 41 is activated, and the second mover 44 and the second slider 45 reciprocate horizontally relative to the second stator 43. The second slider 45 is added to guide and limit the movement of the sliding seat 1 42, thereby improving the stability and accuracy of the first driver 41 in driving the pressure jaw assembly 6 in the horizontal direction. The second grating scale 47 is set on the second slider 45, and the second slider 45 drives the second grating scale 47 to reciprocate horizontally relative to the second stator 43. The second reading head 46 reads the numerical changes of the second grating scale 47 and sends the read numerical values ​​to the controller. After receiving the numerical values ​​sent by the second reading head 46, the controller analyzes and determines them, thereby controlling the output frequency of the first driver 41, further achieving precise control of the motion trajectory of the pressure jaw assembly 6. The second stator 43, the second mover 44, the second reading head 46, and the second grating scale 47 are all arranged in the accommodating space, and the first driver 41 is less exposed during the movement, thereby improving the dustproof effect and safety performance of the first driver 41. Preferably, both the first grating scale 57 and the second grating scale 47 may be coding scales, and both the first reading head 56 and the second reading head 46 may be encoders.

[0043] Furthermore, the first displacement mechanism 4 further includes a second sensing piece 49 connected to the second sliding member 45 and a second sensing switch 48 provided on the crossbeam 52 . The second sensing switch 48 is used for sensing the second sensing piece 49 and sending a sensing signal.

[0044] Specifically, the second sensing switch 48 is electrically connected to the controller. Both the first sensing plate 59 and the second sensing plate 49 can be photoelectric sensing plates. The first sensing switch 58 and the second sensing switch 48 can be photoelectric sensing switches. The second sensing switch 48 is used to sense the second sensing plate 49 and send a sensing signal to the controller. In actual use, the second sliding member 45 drives the second sensing plate 49 to reciprocate horizontally relative to the second stator 43. When the second sensing switch 48 senses the second sensing plate 49 and sends a sensing signal to the controller, the controller receives the sensing signal and controls the first driver 41 to stop or reverse direction, further improving the accuracy of the pressure jaw assembly 6 during operation.

[0045] Furthermore, the pressure claw assembly 6 includes an elastic structure 61, a mounting seat 62 arranged on the sliding seat 1 42, a sliding seat 2 63 movably arranged on the mounting seat 62, and a pressure plate 1 64 and a pressure plate 2 65 respectively connected to the sliding seat 2 63; a connecting column 66 is provided on the sliding seat 2 63, one end of the elastic structure 61 is connected to the connecting column 66, and the other end of the elastic structure 61 is connected to the mounting seat 62; the pressure plate 1 64 and the pressure plate 2 65 can be used to compress the battery electrode.

[0046] Specifically, the mounting seat 62 is slidably connected to the second sliding seat 63; the elastic structure 61 can be a tension spring. In actual use, the pressing drive device 2 drives the pressing claw assembly 6 to move above the battery electrode and drives the pressing claw assembly 6 to press the battery electrode and diaphragm downward. When the pressure plate 1 64 and / or the pressure plate 2 65 come into contact with the battery electrode, the battery electrode provides a reverse force to the pressure plate 1 64 and / or the pressure plate 2 65, causing the pressure plate 1 64 and / or the pressure plate 2 65 to drive the second sliding seat 63 to slide upward relative to the mounting seat 62. The connecting column 66 stretches the elastic structure 61. The tension of the elastic structure 61 drives the second sliding seat 63, the pressure plate 1 64 and the pressure plate 2 65 to maintain the force of pressing the battery electrode downward, thereby completing the compression of the battery electrode. The sliding seat 2 63 is slidably connected to the mounting seat 62, so that the pressure plate 1 64 and the pressure plate 2 65 can generate an upward buffering force after contacting the battery pole piece, avoiding a hard collision between the pressure plate 1 64 and the pressure plate 2 65 and the battery pole piece, thereby improving the service life of the pressure plate assembly; the elastic structure 61 can also pull the pressure plate 1 64 and the pressure plate 2 65 to always maintain the state of pressing the battery pole piece, thereby improving the quality of pressing the battery pole piece. In addition, by detecting the tensile force of the elastic structure 61, the magnitude of the pressing force of the pressure plate 1 64 and the pressure plate 2 65 on the battery pole piece can be measured, and the magnitude of the pressure exerted by the pressure plate 1 64 and the pressure plate 2 65 on the battery pole piece can be accurately controlled. The addition of the connecting column 66 is conducive to the rapid installation and connection of the elastic structure 61, the sliding seat 2 63 and the mounting seat 62.

[0047] Furthermore, the outer side wall of the mounting seat 62 is recessed inward to form a sliding groove 67, one end of the connecting column 66 is connected to the elastic structure 61, and the middle part of the connecting column 66 is inserted into the sliding seat 2 63; the other end of the connecting column 66 can protrude into the sliding groove 67 and be slidably connected to the sliding groove 67.

[0048] Specifically, the middle portion of the connecting post 66 is fixedly connected to the second sliding seat 63. When the second sliding seat 63 slides relative to the mounting seat 62, the connecting post 66 can slide up and down within the sliding slot 67. By varying the vertical length of the sliding slot 67, the travel of the connecting post 66 and the second sliding seat 63 relative to the mounting seat 62 can be varied. This also prevents the second sliding seat 63 from sliding excessively relative to the mounting seat 62, which could cause the elastic structure 61 to exceed its elastic limit. This improves the stability of the pressing claw assembly 6 during the process of compressing the battery electrode.

[0049] Specifically, a cross roller slide 68 is provided between the mounting seat 62 and the second sliding seat 63. The cross roller slide 68 is connected to the mounting seat 62 and the second sliding seat 63 respectively. The mounting seat 62 has good stability and smoothness when sliding relative to the second sliding seat 63.

[0050] Furthermore, the pressure claw assembly 6 also includes a connecting member 69 arranged on the sliding seat 2 63, and the connecting member 69 includes a connecting plate 1 72 connected to the pressure plate 1 64 at one end, a connecting plate 2 70 connected to the pressure plate 2 65 at one end, and a C-shaped plate 71 connected to the other ends of the connecting plate 1 72 and the connecting plate 2 70 respectively.

[0051] In actual use, the pressure plate 1 64 and the pressure plate 2 65 are connected respectively by connecting plate 1 72 and connecting plate 2 70, and a C-shaped plate 71 is added to increase the distance between the pressure plate 1 64 and the pressure plate 2 65, so that the pressure plate 1 64 and the pressure plate 2 65 can press the battery electrodes at intervals. At the same time, the C-shaped plate 71 can also avoid other components. The structure of the connector 69 is simple and the production is convenient. Specifically, the clamping drive device 2 and the two clamping claw assemblies 6 form a group of clamping units. The number of clamping units can be set to two groups. The two groups of clamping units are arranged side by side, and the connecting piece 69 of one clamping unit and the connecting piece 69 of the other adjacent clamping unit are staggered front and back. The pressure plate 65 of one clamping unit can protrude into the opening of the C-shaped plate 71 of the other clamping unit, so that the two clamping units can simultaneously loosen the battery pole piece upward or press it downward. The design structure of the C-shaped plate 71 is simple and ingenious, the structure of the clamping unit is compact, and the movements of the two clamping units do not interfere with each other, thereby improving the clamping efficiency of the battery pole piece.

[0052] Furthermore, the stacking table device 3 includes a driving component 31 arranged on the base 1, a support base 32 connected to the output end of the driving component 31, a stacking table 33 connected to the support base 32, and a connecting base 34 connected to the base 1 and the support base 32, and the connecting base 34 is slidably connected to the support base 32; the support base 32 is T-shaped.

[0053] Specifically, there are two connecting blocks 34, which are arranged opposite and parallel to each other, one on either side of the support base 32. The stacking platform device 3 is located between the two pressing units. In actual use, the drive assembly 31 drives the support base 32 and stacking platform 33 to reciprocate vertically. The support base 32 slides relative to the two connecting blocks 34, thereby stably adjusting the vertical height of the stacking platform 33 and facilitating the stacking and pressing of battery electrodes on the stacking platform 33. The addition of the connecting blocks 34 guides and limits the movement of the support base 32, facilitating stable and precise reciprocating movement of the support base 32 and stacking platform 33. The connection structure of the connecting blocks 34 to the support base 32 and the base 1, respectively, is simple and compact, ensuring smooth movement. The present invention also facilitates the manufacture and processing of the connecting blocks 34 and the support base 32. The T-shaped support base 32 increases the contact area between the stacking platform 33 and the support base 32, improving the stability of the connection between the stacking platform 33 and the support base 32.

[0059] S4: The second driver 51 drives the pressing claw assembly 6 to move upward, and then the first driver 41 drives the pressing claw assembly 6 to move outward away from the lamination table device 3;
