Description

Technical Field

[0001] The utility model relates to the technical field of battery manufacturing, in particular to a clamping device of a battery capping device. Background Art

[0002] Most of the capping methods of storage batteries adopt glue sealing, which requires injecting glue into the battery cover, and then inverting the battery main body and pressing it on the battery cover to complete the capping operation. Conventionally, it is all manually assembled, that is, the worker lifts the entire battery main body, turns it over and inverts it, and then presses it on the battery cover. Since the storage battery is heavy, the labor intensity of manual capping is large, and the capping quality cannot be guaranteed. Nowadays, mechanized battery capping devices are mostly used for the assembly of the battery main body and the battery cover.

[0003] The operation process of the battery capping device is as follows: first, the battery main body is clamped, and after clamping, it is rotated 180° to make it in an inverted state. Then, the battery main body moves downward and is pressed on the battery cover that has been injected with glue, and thus the capping operation of a storage battery is completed. For example, an automatic capping machine for lead-acid batteries previously applied by our unit, patent publication number CN213483845U, sequentially includes a bus bar detection device, a flipping device and a capping device from left to right. Among them, the capping device can drive the inverted battery main body to move above the battery cover, and then descend and press it on the battery cover on the belt conveyor.

[0004] The above-mentioned publicly disclosed patent introduces the specific structure, principle and working process of the capping device. The mechanical fixture therein is a jaw structure. For a cuboid battery main body, only two gripping plates are used to clamp both sides of the battery main body, and the contact area between the two is small, and the reliability of clamping is difficult to guarantee. Moreover, the battery cover is conveyed by conveyor belt four, and the battery cover has no positioning mechanism. Therefore, during the process of pressing the battery main body downward on the battery cover, the battery cover is not fixed and may shift, which not only affects the capping progress, but also may cause capping errors and affect the normal assembly operation. Summary of the Invention

[0005] In order to solve the problems of low clamping reliability of the mechanical fixture for the battery main body and easy offset of the battery cover without positioning, the utility model provides a clamping device of a battery capping device, and respectively proposes a clamping mechanism for the battery main body and the battery cover, which can realize reliable clamping of the battery main body and positioning and fixing of the battery cover, and ensure the accuracy of the capping operation.

[0006] To achieve the above object, the technical solution adopted by the utility model is:

[0007] A clamping device for a battery capping device comprises an upper clamping mechanism for clamping a battery body and a lower clamping mechanism for clamping a battery cover, wherein the upper clamping mechanism comprises a top plate, a bidirectional screw controlled by a motor and an upper clamping assembly, wherein the bidirectional screw is rotatably arranged on the top plate, the motor is convenient for driving the bidirectional screw to rotate, and the upper clamping assembly is symmetrically arranged at both ends of the bidirectional screw axis, so that the upper clamping assembly can move relative to or away from each other conveniently;

[0008] The upper clamping assembly includes a nut seat, a vertical plate and a clamping frame plate. The nut seat is meshed with a bidirectional screw rod to facilitate the movement of the nut seat. The nut seat slides linearly along the top plate. The vertical plate is arranged below the nut seat. The vertical plate passes through the top plate downward. The clamping frame plates for clamping the corners of the battery body are symmetrically arranged on both sides of the vertical plate, so as to facilitate clamping the four corners of the battery body.

[0009] There are two lower clamping mechanisms, which are symmetrically arranged. The lower clamping mechanisms include a base plate and a positioning plate frame controlled by a push cylinder. The positioning plate frame is slidably arranged on the base plate. The positioning plate frames on the two lower clamping mechanisms cooperate to clamp the diagonals of the battery cover, which is convenient for positioning and fixing the battery cover.

[0010] Furthermore, the two ends of the bidirectional screw are rotatably connected through the bearing seat and the top plate, which improves the smoothness of the rotation of the bidirectional screw. The spiral rotation directions of the two ends of the bidirectional screw are opposite, which can ensure that the upper clamping components at both ends of the bidirectional screw can slide left and right along the top plate relative to or away from each other.

[0011] Furthermore, the middle part of the nut seat is meshed with the bidirectional screw rod, and a slide rail slider structure is provided between the two ends of the nut seat and the top plate for sliding connection. A long sliding hole is opened in the top plate, and the vertical plate passes through the long sliding hole and extends to the bottom of the top plate to prevent the top plate from interfering with the left and right movement of the vertical plate.

[0012] Furthermore, the cross-section of the vertical plate is in the shape of a Chinese character "丄", and two upper and lower adjustment long holes are provided on the vertical plate to facilitate the position adjustment of the clamping frame plate. The length direction of the adjustment long hole is perpendicular to the axial direction of the bidirectional screw rod, and the clamping frame plates are symmetrically and movably connected on both sides of the vertical plate to facilitate the adjustment of the spacing between the clamping frame plates on both sides to adapt to battery bodies of different specifications and sizes. The clamping frame plate is bent into a "﹂" shape to match the contour of the corners of the battery body to facilitate its clamping.

[0013] Furthermore, the clamping frame plate includes two horizontal clamping plates arranged in parallel up and down and a vertical clamping plate arranged between the two horizontal clamping plates, and the cross section of the horizontal clamping plate and the vertical clamping plate after being connected and assembled is in a "﹂" shape;

[0014] The transverse clamping plate and the adjusting long hole correspond one to one, and a mounting shaft is arranged at the end of the transverse clamping plate. The mounting shaft passes through the adjusting long hole and is connected with a mounting nut to facilitate locking and unlocking of the clamping frame plate.

[0015] Furthermore, a slide rail and slider structure is provided between the positioning plate frame and the bottom plate for sliding connection. The positioning plate frame includes a rear plate, a connecting plate, and a front plate. The rear plate is connected to the piston rod of the pushing cylinder. The connecting plate is arranged between the rear plate and the front plate. The front plate is bent in a "﹂" shape. The front plates of the two lower clamping mechanisms respectively hold the diagonal positions of the battery cover, facilitating the positioning and fixing of the battery cover.

[0016] Through the above technical solutions, the beneficial effects of the present utility model are as follows:

[0017] The structure of the present utility model is reasonably designed. The upper clamping mechanism facilitates reliable clamping of battery bodies of different specifications and sizes, avoiding loosening. The bidirectional lead screw is driven by a motor to rotate. The upper clamping components at both ends of the bidirectional lead screw facilitate synchronous relative or opposite movement. When moving relatively, the battery body can be clamped, and when moving in opposite directions, the battery body can be released. The clamping frame plates are adjustable on both sides of each vertical plate, and the distance between the clamping frame plates can be changed to adapt to battery bodies of different specifications and sizes. By clamping the four corner positions of the battery body with four clamping frame plates, the reliability and stability of clamping can be ensured.

[0018] The number of the lower clamping mechanisms of the present utility model is two and they are symmetrically arranged. The two lower clamping mechanisms cooperate with each other to facilitate the positioning and fixing of the battery cover. The pushing cylinder drives the positioning plate frames to approach each other. The front end of the positioning plate frame is bent in a "﹂" shape, and the bending directions of the front ends of the positioning plate frames on both sides are different. This enables the positioning plate frames on both sides to conveniently hold the diagonal positions of the battery cover, avoiding the offset of the battery cover, ensuring the stability of the battery cover when the battery body is snap-fastened, and ensuring the accuracy of snapping the battery body onto the battery cover.

Detailed implementation manners

[0027] The following will describe in detail the specific implementation manners of the present utility model with reference to the drawings:

[0028] As Figures 1 to 7 shown, a clamping device of a battery capping device includes an upper clamping mechanism 1 for clamping the main body of a storage battery and a lower clamping mechanism 2 for clamping a battery cover. Here, the upper clamping mechanism 1 and the lower clamping mechanism 2 are proposed on the basis of the patent publication number CN213483845U, an automatic capping machine for lead-acid batteries. The upper clamping mechanism 1 is installed on a second lifting driving member and can move up and down under the drive of the second lifting driving member. The upper clamping mechanism 1 replaces a mechanical fixture to grasp the main body of the storage battery. The lower clamping mechanism 2 is installed on the frame of a fourth conveyor belt and is used to position and fix the battery cover.

[0029] In this embodiment, the upper clamping mechanism 1 includes a top plate 3, a bidirectional lead screw 4 controlled by a motor, and an upper clamping assembly 5, as Figure 1 and Figure 2 shown. The bidirectional lead screw 4 is rotatably arranged on the top plate 3. Specifically, both ends of the bidirectional lead screw 4 are rotatably connected to the top plate 3 through bearing seats 6. The rotation of the bidirectional lead screw 4 is controlled by a motor, and the motor is not shown in the figure.

[0030] The spiral directions at both ends of the bidirectional lead screw 4 are opposite. The upper clamping assemblies 5 are symmetrically arranged at both axial ends of the bidirectional lead screw 4. Therefore, when the bidirectional lead screw 4 operates, the upper clamping assemblies 5 at both ends of the bidirectional lead screw 4 slide left and right relative to or away from each other along the top plate 3. When moving relatively, the upper clamping assemblies 5 approach each other and can clamp the main body of the storage battery. When moving away from each other, the upper clamping assemblies 5 move away from each other and are used to release the main body of the storage battery.

[0031] The upper clamping assembly 5 includes a nut seat 51, a vertical plate 52 and a clamping frame plate 53. The nut seat 51 is meshed with the bidirectional screw 4, and the nut seat 51 slides linearly along the top plate 3. Specifically, the middle part of the nut seat 51 is meshed with the bidirectional screw 4, and the operation of the bidirectional screw 4 can drive the nut seat 51 to move linearly. A slide rail and slider structure is provided between the two ends of the nut seat 51 and the top plate 3 for sliding connection. The slide rail and slider structure includes slide rails and sliders. Slide rails are provided on both sides of the top plate 3, and the slide rails are arranged in parallel on both sides of the bidirectional screw 4. At the same time, sliders are provided at both ends below the nut seat 51, and the sliders move along the slide rails.

[0032] A vertical plate 52 is arranged below the nut seat 51, and the vertical plate 52 passes through the top plate 3 downwardly, and the nut seat 51 drives the vertical plate 52 to move left and right together. In order to prevent the top plate 3 from interfering with the movement of the vertical plate 52, a long sliding hole 7 is opened in the top plate 3, and the long sliding hole 7 provides a space for the vertical plate 52 to slide left and right, and the vertical plate 52 passes through the long sliding hole 7 and extends to the bottom of the top plate 3.

[0033] The cross section of the vertical plate 52 is in the shape of a Chinese character "丄". Clamping frame plates 53 for clamping the corners of the battery body are symmetrically arranged on both sides of the vertical plate 52. The clamping frame plates 53 are bent into a "﹂" shape, thereby clamping a corner position of the battery body. The clamping frame plates 53 on both sides are arranged in a "[" shape, which can clamp the two corner positions of the battery body.

[0034] In order to clamp the battery bodies of different specifications and sizes, two upper and lower adjustment holes 8 are opened on the vertical plate 52. The adjustment holes 8 are waist-shaped holes, and the length direction of the adjustment holes 8 is perpendicular to the axial direction of the bidirectional screw rod 4. The vertical plate 52 is symmetrically and movably connected with the clamping frame plates 53 on both sides, that is, the clamping frame plates 53 can be horizontally moved relative to the vertical plate 52, thereby changing the spacing between the clamping frame plates 53 on both sides, so that the battery bodies of different specifications can be clamped, such as Figure 3 and Figure 4 shown.

[0035] Specifically, the clamping frame plate 53 includes two horizontal clamping plates 532 arranged in parallel up and down and a vertical clamping plate 531 disposed between the two horizontal clamping plates 532. The vertical clamping plate 531 can connect and fix the two horizontal clamping plates 532. After the horizontal clamping plates 532 and the vertical clamping plates 531 are connected and combined, the cross section is in a "﹂" shape and the longitudinal section is in a "匚" shape. The horizontal clamping plates 532 correspond to the long adjustment holes 8 one by one. The ends of the horizontal clamping plates 532 are provided with mounting shafts 9. The mounting shafts 9 pass through the long adjustment holes 8 and are connected with mounting nuts 10.

[0036] After loosening the mounting nut 10, the clamping frame plate 53 is in an adjustable state. Horizontally move the clamping frame plate 53 horizontally, and then the mounting shaft 9 moves within the adjusting long hole 8. After moving to a certain position, reverse-tighten the mounting nut 10 to fix the clamping frame plate 53, thereby changing the distance between the two clamping frame plates 53 on the same vertical plate 52 to match the battery bodies of different specifications.

[0037] The principle of the upper clamping mechanism 1 is as follows: Before operation, first adjust the distance between the clamping frame plates 53 on the same vertical plate 52 according to the size of the battery body so that it can just be stuck at the corners of the battery body. As Figure 5 shown, when it is necessary to clamp the battery body, the motor drives the bidirectional lead screw 4 to rotate, and then the two nut seats 51 approach each other, driving their respective vertical plates 52 and clamping frame plates 53 to approach each other until the battery body is clamped. At this time, the four clamping frame plates 53 are clamped at the four corners of the battery body, and the battery body can be reliably clamped.

[0038] In order to ensure that both the horizontal clamping plate 532 and the vertical clamping plate 531 of the clamping frame plate 53 can apply a moving clamping force to the battery body, a rubber pad 11 is provided on the inner side wall of the vertical clamping plate 531, and the cross section of the rubber pad 11 is a right trapezoid. In this way, the horizontal clamping plate 532 can apply a clamping force to the battery body under the drive of the bidirectional lead screw 4. After the vertical clamping plate 531 contacts the battery body, the rubber pad 11 gradually deforms, and then it can also apply a clamping force to the battery body, so that clamping forces can be applied to the four corners of the battery body to ensure the reliability of clamping.

[0039] In this embodiment, the number of the lower clamping mechanisms 2 is two and they are symmetrically arranged. The lower clamping mechanism 2 includes a bottom plate 12 and a positioning plate frame 14 controlled by a pushing cylinder 13. The positioning plate frame 14 is slidably arranged on the bottom plate 12. Specifically, a slide rail and slider structure is provided between the positioning plate frame 14 and the bottom plate 12 for sliding connection. The slide rail and slider structure is the same as the above and will not be elaborated here.

[0040] After the positioning plate frames 14 on the two lower clamping mechanisms 2 approach each other, they cooperate to clamp the diagonal corners of the battery cover, as Figure 6 shown. Specifically, the positioning plate frame 14 includes a rear plate 141, a connecting plate 142 and a front plate 143. The rear plate 141 is connected to the piston rod of the pushing cylinder 13. A connecting plate 142 is provided between the rear plate 141 and the front plate 143. The number of the connecting plates 142 is two, and the rear plate 141 and the front plate 143 are connected and fixed by the two connecting plates 142. The front plate 143 is bent in a "﹂" shape and can clamp one corner position of the battery cover. The front plates 143 of the two lower clamping mechanisms 2 respectively clamp the diagonal corner positions of the battery cover, that is, the front plates 143 on both sides are arranged in a "「」" shape.

[0041] The principle of the lower clamping mechanism 2 is as follows: The lower clamping mechanisms 2 are symmetrically installed on both sides of the four-frame of the conveyor belt. In this way, when the battery cover moves into the working range of the lower clamping mechanism 2, the conveyor belt four stops running, and then the two lower clamping mechanisms 2 run synchronously. As Figure 7 shown, the pushing cylinder 13 drives the entire positioning plate frame 14 close to the battery cover until the front plate 143 is clamped at a corner position of the battery cover. By simultaneously clamping the front plates 143 on both sides at the diagonal positions of the battery cover, the positioning and fixing of the battery cover are realized, preventing the battery cover from shifting and ensuring that the battery body can accurately press-fit on the battery cover.

[0042] The above-described embodiments are only the preferred embodiments of the present invention and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features, and principles described in the scope of the present invention patent should be included in the scope of the present invention's patent application.
