[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0033] In this embodiment, Figure 1 As shown, it includes a truss 1, an X-axis assembly 2, a Y-axis assembly 3, a Z-axis assembly 4 and a swing plate assembly 5. The truss 1 includes a table top and supporting legs under the table top. The X-axis assembly 2 is arranged on the truss 1. The X-axis assembly 2 includes two parallel first linear guide rails 21. The table top is hollow in the middle. The two first linear guide rails 21 are located on the table top and are respectively fixed on both sides of the hollow area.

[0034] The X-axis assembly 2 also includes a first push plate 20. Both sides of the bottom of the first push plate 20 are provided with first slide grooves 22. The first slide grooves 22 are slidably matched with the corresponding first linear guide rails 21. That is, the number of the first slide grooves 22 and the first linear guide rails 21 are both two. The first push plate 20 is synchronously slidably matched with the two first linear guide rails 21 through the first slide grooves 22, so that the first push plate 20 slides more smoothly.

[0035] The X-axis assembly 2 also includes a first rack 23 arranged on the truss 1. The first rack 23 is arranged in the same direction as the first linear guide 21. The first push plate 20 is provided with a first gear 24 meshing with the first rack 23. The first gear 24 is connected to a first driving member 514. The first driving member 514 drives the first gear 24 to rotate. The first gear 24 cooperates with the first rack 23, thereby driving the first push plate 20 to move, thereby realizing the reciprocating motion of the first push plate 20 in the X-axis direction.

[0036] The Y-axis assembly 3 includes a fixed plate 30 and a second push plate 31. The fixed plate 30 is connected to the first push plate 20. The fixed plate 30 moves in the X-axis direction with the first push plate 20. The fixed plate 30 is perpendicular to the first push plate 20. A second linear guide 32 is provided on the fixed plate 30, so that the second linear guide 32 is perpendicular to the first linear guide 21. Since the first linear guide 21 is located on both sides of the first push plate 20, the fixed plate 30 is located on the first push plate 20, and the second linear guide 32 is located on the fixed plate 30, the second linear guide 32 is located between the two first linear guides 21. A second slide groove is provided at the bottom of the second push plate 31. The second push plate 31 is slidably matched with the second linear guide 32 through the second slide groove, so that the second push plate 31 can reciprocate along the fixed plate 30. Since the first linear guide 21 and the second linear guide 32 are arranged perpendicular to each other, the second push plate 31 can reciprocate in the Y-axis direction and the X-axis direction at the same time.

[0037] The Y-axis assembly 3 also includes a second rack 33 arranged on the fixed plate 30 and in the same direction as the second linear guide rail 32. The second push plate 31 is provided with a second gear 34 meshing with the second rack 33. The second gear 34 is connected to a second driving member 517. The second driving member 517 drives the second gear 34 to rotate. The second gear 34 cooperates with the second rack 33, thereby driving the second push plate 31 to move along the fixed plate 30, that is, driving the second push plate 31 to make reciprocating motion in the Y-axis direction.

[0038] There are two second linear guide rails 32 , which are arranged parallel to each other on the fixing plate 30 , so that the second push plate 31 can move more stably.

[0039] The Z-axis assembly 4 includes a third push plate 40 and a positioning plate 41 connected to the second push plate 31. The positioning plate 41 is provided with a third linear guide rail 42 which is perpendicular to the second linear guide rail 32. A third slide groove is provided at the bottom of the third push plate 40. The third push plate 40 is slidably matched with the third linear guide rail 42 through the third slide groove, so that the third push plate 40 can reciprocate along the positioning plate 41. Since the third linear guide rail 42 is perpendicular to the second linear guide rail 32, the third push plate 40 can reciprocate in the Z-axis direction along the Y-axis assembly 3. The Z-axis assembly 4 also includes a third driving member for driving the third push plate 40 to slide reciprocatingly along the third linear guide rail 42. The corresponding pipeline of the third driving member is bound and protected by a tank chain. Finally, the third push plate 40 can reciprocate in the X-axis, Y-axis and Z-axis directions relative to the truss 1.

[0040] The swing plate assembly 5 includes a mounting plate 50 vertically connected to the lower end of the third push plate 40. The mounting plate 50 is detachably provided with a base 51. The mounting plate 50 moves with the third push plate 40. The mounting plate 50 is provided with a base 51. The base 51 is detachably installed on the mounting plate 50. Two moving blocks 52 are slidably connected to the base 51. The base 51 is provided with a guide rail 512. The moving blocks 52 are provided with a guide groove 513 that slidably cooperates with the guide rail 512. The two moving blocks 52 reciprocate along the guide rail 512 under the drive of their respective fourth driving members. Since the guide rail 512 is a linear guide rail 512, the two moving blocks 52 make a relatively close or away translational motion along the linear guide rail 512. Each moving block 52 is provided with a first comb plate 53. A plurality of first teeth 54 are equidistantly distributed on the surface of the first comb plate 53. The first teeth 54 on the same comb plate are parallel to each other and are arranged along a straight line as a whole, so that the two first comb plates 53 and their respective first teeth 54 are parallel to each other and symmetrically arranged.

[0041] A first tooth groove 55 is formed between two adjacent first teeth 54 on the first comb plate 53. In the present embodiment, the width of the first tooth groove 55 is slightly larger than the thickness of the top cover sheet 59 to ensure that each first tooth groove 55 can be inserted with a top cover sheet 59. The first tooth groove 55 has a certain depth so that after the top cover sheet 59 is inserted into the first tooth groove 55, the top cover sheet 59 can be stably placed in the first tooth groove 55.

[0042] A second comb tooth plate 56 is provided on one side of each first comb tooth plate 53. In this embodiment, there are two second comb tooth plates 56, which correspond to the first comb tooth plates 53 one by one. The two second comb tooth plates 56 are respectively located on the outer sides opposite to the two first comb tooth plates 53. The second comb tooth plates 56 and the corresponding first comb tooth plates 53 are arranged close to and parallel to each other. A slide groove 515 is opened on the side of each second comb tooth plate 56, and a slider 516 that slidably cooperates with the slide groove 515 is provided on the corresponding first comb tooth plate 53. The second comb tooth plate 56 is also connected to a fifth driving member. The second comb tooth plate 56 slides back and forth along the first comb tooth plate 53 under the drive of the fifth driving member. The sliding between the first comb tooth plate 53 and the second comb tooth plate 56 The direction is relatively vertical, and second teeth 57 corresponding to the first teeth 54 are distributed on the surface of the second comb plate 56. A second tooth groove 58 is formed between two adjacent second teeth 57 on the second comb plate 56, and the top cover piece 59 is inserted into the second tooth groove 58. Since the first tooth groove 55 and the second tooth groove 58 are arranged flush, the top cover piece 59 is also inserted into the first tooth groove 55 when inserted into the second tooth groove 58. When the first comb plate 53 and the second comb plate 56 slide relatively, the first teeth 54 on the first comb plate 53 and the second teeth 57 on the second comb plate 56 are staggered with each other, so that the first tooth groove 55 and the second tooth groove 58 are staggered with each other, so that the top cover piece 59 can be stably clamped.

[0043] The moving block 52 is provided with a mounting groove, and the first comb plate 53 is mounted in the mounting groove by a fastener, so that the first comb plate 53 remains stationary relative to the moving block 52 .

[0044] There are two moving blocks 52, and two first comb plates 53. The relative distance between the two first comb plates 53 can be adjusted by corresponding moving blocks 52, so that the first comb plates 53 can clamp top cover sheets 59 of different lengths. The second comb plate 56 is slidably connected to the first comb plate 53, so it moves with the first comb plate 53.

[0045] The base 51 is provided with a pushing portion 510 between the two first comb tooth plates 53. In the present embodiment, the pushing portion 510 is a push plate structure, which is arranged along the length direction of the first comb tooth plate 53 or the second comb tooth plate 56. A guide telescopic rod 520 structure is provided between the base 51 and the pushing portion 510. A sixth driving member is also provided on the base 51. The pushing portion 510 moves back and forth along the guide telescopic rod 520 under the push of the sixth driving member, that is, the pushing portion 510 moves back and forth along the depth direction of the first tooth groove 55 or the second tooth groove 58, so that the pushing portion 510 pushes all the top cover plates 59 away from the first tooth groove 55 and the second tooth groove 58 at one time.

[0046] In this embodiment, since the first teeth 54 and the second teeth 57 are teeth of a vertical plate-shaped structure perpendicular to the bottom of the corresponding comb plate, the first tooth groove 55 and the second tooth groove 58 are also vertical tooth grooves, the depth dimension of the second tooth groove 58 is smaller than the depth dimension of the first tooth groove 55, and the bottom of the second tooth groove 58 is aligned with the bottom of the first tooth groove 55, so the top opening end of the first tooth groove 55 is higher than the top opening end of the second tooth groove 58, and the top cover sheet 59 is first inserted from the first tooth groove 55 and then inserted into the second tooth groove 58. Usually, the depth dimension of the second tooth groove 58 is half of the depth dimension of the first tooth groove 55.

[0047] In this embodiment, the width dimension of the second tooth groove 58 is less than or equal to the width dimension of the first tooth groove 55, that is, when the first tooth groove 55 and the second tooth groove 58 are flush with each other, when the top cover sheet 59 is inserted into the first tooth groove 55 and then into the second tooth groove 58, there will be no contact between the top cover sheet 59 and the inner wall of the second tooth groove 58 or excessive friction. In this embodiment, the material of the first teeth 54 is ceramic, and the material of the second teeth 57 is engineering plastic. Ceramics have high hardness and a smooth surface, and will not cause secondary pollution to the top cover sheet 59 such as the battery panel, so as to affect the subsequent processing technology; engineering plastics have elastic deformation ability, so that the second teeth 57 can be more stable when pressing the top cover sheet 59, thereby avoiding displacement of the top cover sheet 59 during movement.

[0048] The material of the first comb plate 53 is also ceramic, which can be processed by 3D printing to achieve a special structure while ensuring the surface smoothness and overall hardness; the material of the second comb plate 56 is also engineering plastic.

[0049] A protrusion 511 is provided on the top inner wall of the second tooth 57, and the protrusion 511 is designed as an integral part of the second tooth 57. The protrusion 511 is arranged in the direction of shifting toward the second tooth 57 and pressing the top cover sheet 59, that is, the protrusion 511 is arranged on the inner wall of one side of the second tooth groove 58. When the second tooth 57 shifts relative to the first tooth 54, the protrusion 511 is just pressed against the surface of the top cover sheet 59, so that the top cover sheet 59 can be stably clamped. The second tooth 57 contacts with the top cover sheet 59 through the protrusion 511, and the contact area is very small, while minimizing the risk of the surface of the top cover sheet 59 being damaged.

[0050] The first comb plate 53 is provided with a limiting bolt, so that the displacement of the second comb plate 56 relative to the first comb plate 53 can be adjusted to achieve the deformation of the second teeth 57 when the protrusion 511 presses the top cover plate 59, thereby preventing the second teeth 57 from being excessively deformed.

[0051] The tops of the protrusion 511 and the second tooth 57 form smooth arc surfaces to prevent scratches on the surface of the top cover sheet 59; the bottom right angles of the first tooth groove 55 and the second tooth groove 58 are rounded to avoid contact or friction with the sharp edges of the top cover sheet 59.

[0052] The top of the first tooth 54 is in a V-shaped structure and has a smooth transition with the tooth body. The V-shaped top is rounded. In this embodiment, the radius of the rounded corner is 0.5mm, which not only prevents the right-angled top from scratching the surface of the top cover piece 59 when the top cover piece 59 is inserted, but also improves the ceramic strength of the top, and is not easy to fall off when impacted.

[0053] In this embodiment, the top cover piece 59 is a battery cover plate of a new energy lithium battery, which is a rectangular top cover piece 59 structure. When processing the battery cover plates, the battery cover plates are arranged in batches and placed on the discharge tray at intervals. The number of first tooth grooves 55 is 24, and the spacing between adjacent first tooth grooves 55 is 7.85 mm, which is consistent with the setting of the discharge tray, so that the first tooth grooves 55 are moved to the top of the discharge tray. The first tooth grooves 55 can be inserted and clamped one by one for the battery cover plates to be inserted and clamped, thereby realizing direct batch clamping of the battery cover plates.

[0054] The fourth driving member, the fifth driving member and the sixth driving member can all be cylinders, hydraulic cylinders or motors, which are provided with universal interfaces 518 to facilitate the adaptation of the clamp to different manipulators.

[0055] Since the mounting plate 50 is vertically arranged relative to the third push plate 40, the teeth of the first comb plate 53 and the second comb plate 56 are both perpendicular to the mounting plate 50, and the mounting plate 50 is linearly translated along the X-axis, Y-axis and Z-axis, the top cover piece 59 clamped by the first comb plate 53 on the mounting plate 50 is in the same direction as the teeth, that is, perpendicular to the mounting plate 50, so that the top cover piece 59 is exchanged between the two swing plate assemblies 5, that is, the first comb plate 53 of one swing plate assembly 5 moves to the first comb plate 53 of the other swing plate assembly 56 clamping the top cover piece 59. The top cover piece 59 is pushed by the pushing portion 510 so that the top cover piece 59 moves from the tooth grooves of the first comb plate 53 and the second comb plate 56 of the first swing plate assembly 5 to the tooth grooves of the first comb plate 53 and the second comb plate 56 of the second swing plate assembly 5 to complete the transfer and exchange of the top cover piece 59. That is, the top cover piece 59 can be horizontally moved from one swing plate assembly 5 to another swing plate assembly 5 under the push of the pushing portion 510, which is very convenient.

[0056] The first gear 24 and the second gear 34 are driven to rotate by the first driving member 514 and the second driving member 517 respectively. The corresponding pipelines of the first driving member 514, the second driving member 517 and the third driving member are bound and protected by tank chains. The above-mentioned racks are fixed by fasteners. The first driving member 514, the second driving member 517 and the third driving member are servo motors with reducers. Of course, when the load on the mounting plate 50 is small, the third driving member can directly use a finished electric cylinder.

[0057] In this embodiment, the length-to-width ratio of the first push plate 20 is 2:1, and the first linear guide rail 21 is located at the width position of the first push plate 20, which not only ensures the rigidity and stability of the first push plate 20, thereby increasing the service life of the first linear guide rail 21. In addition, a reinforcing rib 6 is provided between the first push plate 20 and the fixed plate 30, so that the stability of the fixed plate 30 can be maintained when the fixed plate 30 is vertically arranged on the first push plate 20.

[0058] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present application fall within the protection scope of the present utility model.
