Description

Technical Field

[0001] The utility model relates to a device for making storage batteries, in particular to a device for clamping a storage battery electrode group. Background Art

[0002] In the process of making storage batteries, it is necessary to transfer the grouped electrode groups into the battery cell. Currently, the electrode groups are usually clamped and transferred by clamping jaws. The clamping jaws generally include two clamping plates driven by a single air cylinder to clamp or loosen. For example, the invention application with the application number CN201310251832.6 and the name of "a clamping and feeding into the groove mechanism of a storage battery laminating and feeding into the groove machine", and the invention patent with the application number CN202311378593.0 and the name of "a storage battery electrode group shaping, cutting, brushing and feeding into the groove integrated machine" are all like this. In this structure where a single air cylinder drives the two clamping plates to move, since the stroke of the air cylinder is fixed, that is, the amplitude of loosening or clamping the clamping jaws is limited and cannot be adjusted arbitrarily, but only within the stroke range of the air cylinder. Therefore, for different models of storage battery electrode groups, the clamping jaws may not be universal. Content of the Utility Model

[0003] Aiming at the problem that in the current general operation where a single air cylinder drives the entire clamping jaw to move, the adjustment amplitude of loosening or clamping the clamping jaw is limited, the utility model provides a device for clamping a storage battery electrode group, which can arbitrarily adjust the distance between the two clamping plates as needed.

[0004] The technical means adopted by the utility model to solve the above problems is as follows: A device for clamping a storage battery electrode group includes a clamping mechanism. The clamping mechanism includes a bracket and a left clamping component and a right clamping component arranged on the bracket. The bracket includes supporting plates arranged at both ends and a support rod whose two ends are respectively connected to the two supporting plates. The left clamping component includes a left end air cylinder arranged on the left supporting plate, and a left clamping plate through which the support rod passes and is driven to move left and right by the left end air cylinder. The right clamping component includes a right end air cylinder arranged on the right supporting plate, and a right clamping plate through which the support rod passes and is driven to move left and right by the right end air cylinder. The left clamping plate and the right clamping plate form a clamping jaw for clamping the electrode group. By controlling the left clamping plate and the right clamping plate of the clamping jaw by different air cylinders, the distance between the left clamping plate and the right clamping plate for opening or clamping can be arbitrarily adjusted, improving the universality of the clamping jaw.

[0005] Furthermore, both the left clamping plate and the right clamping plate are more than two, and the left clamping plate and the right clamping plate are arranged at intervals. The adjacent two left clamping plates are connected by a left adjusting rod, and the adjacent two right clamping plates are connected by a right adjusting rod. The distance between the two clamping jaws is adjusted by changing the length of the adjusting rod.

[0006] Further, the left clamping plate at the leftmost end is connected to the movable end of the left cylinder, and the right clamping plate at the rightmost end is connected to the movable end of the right cylinder. The left cylinder drives all the left clamping plates to move, and the right cylinder drives all the right clamping plates to move.

[0007] Further, the right adjusting rod movably passes through the left clamping plates between the right clamping plate at the rightmost side and the left clamping plate at the leftmost side, so that the right adjusting rod does not interfere with the movement of the left clamping plates.

[0008] Further, the left adjusting rod movably passes through the right clamping plates between the left clamping plate at the leftmost side and the right clamping plate at the rightmost side, so that the left adjusting rod does not interfere with the movement of the right clamping plates.

[0009] Further, there are four support rods, which are respectively connected to the edges of the support plate near the four corners.

[0010] Further, the bracket further includes a connecting plate with both ends respectively connected to the support plate, and the two support plates and the connecting plate together form a concave structure.

[0011] Further, the clamping device further includes a rotating mechanism, which includes a moving frame, a rotating motor and a driving wheel arranged on the moving frame, and a driven wheel movably arranged on the moving frame. The driving wheel is connected to the output end of the rotating motor and rotates under the drive of the rotating motor. The driven wheel is in gear engagement with the driving wheel and is connected to the bracket to drive the bracket to rotate. The clamping jaws are rotated by the rotating motor and the gears to adjust the angle of the pole group entering the slot.

[0012] Further, the clamping device further includes a moving mechanism, which includes a moving plate and an electric cylinder arranged on the moving plate. The movable end of the electric cylinder is connected to the moving frame to drive the rotating mechanism to move up and down. The electric cylinder can accurately control the distance for driving the clamping jaws to rise or fall.

[0013] Further, a guide sleeve is provided on the moving plate, and a guide post passes through the guide sleeve and is connected to the moving frame at one end, providing guidance for the up and down movement of the moving component.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. By splitting the clamping jaws into left clamping plates and right clamping plates respectively controlled by two cylinders, the adjustable distance between the left clamping plates and the right clamping plates is greatly increased, and thus it is easier to be applicable to the clamping of pole groups with different thicknesses.

[0016] 2. By providing multiple left clamping plates connected by adjusting rods and multiple right clamping plates connected by adjusting rods, and cooperating with the left cylinder and the right cylinder, the distance between different clamping jaws can be conveniently adjusted while clamping multiple pole groups at one time, and thus the requirements for the center distance of different pole groups in different storage batteries can be met, greatly improving the versatility of the device.

[0023] The following further describes the present invention with reference to the accompanying drawings. Among them, the accompanying drawings are only for illustrative purposes, showing only schematic diagrams, not physical diagrams, and should not be construed as a limitation to this patent; in order to better illustrate the embodiments of the present invention, some components in the accompanying drawings will be omitted, enlarged or reduced, and do not represent the dimensions of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the accompanying drawings may be omitted. The first embodiment

[0024] A clamping device for a battery electrode group, as Figure 1 shown, the overall includes a translating mechanism 4 for driving the electrode group 5 to move horizontally, a moving mechanism 3 for driving the electrode group 5 to move vertically, a rotating mechanism 2 for driving the electrode group 5 to rotate, and a clamping mechanism 1 for clamping or releasing the electrode group 5. In this embodiment, the translating mechanism 4 drives the entire moving mechanism 3 to move horizontally, the moving mechanism 3 drives the entire rotating mechanism 2 to move vertically, and the rotating mechanism 2 drives the entire clamping mechanism 1 to rotate.

[0025] As Figure 1 , Figure 3 and Figure 4As shown in the figure, the clamping mechanism 1 includes a bracket 11, a left clamping component 12 and a right clamping component 13 arranged on the bracket 11. The bracket 11 includes two support plates 111, a connecting plate 113 and four support rods 112. The two support plates 111 are arranged in parallel at both ends. Both ends of all the support rods 112 are connected to the opposite sides of the two support plates 111. Both ends of the connecting plate 113 are respectively connected to the tops of the two support plates 111, forming an integral body. The left clamping component 12 includes a left-end cylinder 121, a left clamping plate 122 and a left adjusting rod 123. Among them, the left-end cylinder 121 is arranged on the left side surface of the left support plate 111. There are three left clamping plates 122, which are arranged in parallel between the two support plates 111, and all the support rods 112 pass through between all the left clamping plates 122. The left adjusting rod 123 is used to connect two adjacent left clamping plates 122. The leftmost left clamping plate 122 is connected to the movable end of the left-end cylinder 121. The left-end cylinder 121 drives all the left clamping plates 122 to move synchronously along the support rods 112. The right clamping component 13 includes a right-end cylinder 131, a right clamping plate 132 and a right adjusting rod 133. Among them, the right-end cylinder 131 is arranged on the right side surface of the right support plate 111. There are also three right clamping plates 132, which are also arranged in parallel between the two support plates 111, and all the supports 112 pass through between all the right clamping plates 132. The right adjusting rod 133 is used to connect two adjacent right clamping plates 132. The rightmost right clamping plate 132 is connected to the movable end of the right-end cylinder 131. The right-end cylinder 131 drives all the right clamping plates 132 to move synchronously along the support rods 112.

[0026] As Figure 1 - Figure 2 shown in the figure, the rotating mechanism 2 includes a moving frame 21, a rotating motor 22, a driving wheel 23 and a driven wheel 24. The rotating motor 22 is arranged on the moving frame 21. The driving wheel 23 is installed at the output end of the rotating motor 22 and rotates under the drive of the rotating motor 22. The driven wheel 24 is movably installed on the moving frame 21, and the driven wheel 24 is matched with the driving wheel 23. The driven wheel 24 rotates relative to the moving frame 21 under the drive of the driving wheel 23. The driven wheel 24 is connected to the connecting plate 113 of the bracket 11, thereby driving the entire clamping mechanism 1 to rotate synchronously, so that the pole group 5 clamped between the left clamping plate 122 and the right clamping plate 132 can rotate.

[0027] As Figure 1 shown in the figure, the moving mechanism 3 includes a moving plate 31 and an electric cylinder 32. The electric cylinder 32 is arranged on the moving plate 31, and its movable end is connected to the moving frame 21. At the same time, the moving plate 31 is also provided with a guide sleeve 33. The guide post 34 passes through the guide sleeve 33 and is connected to the moving frame 21 at one end. Under the guiding action of the guide post 34, the electric cylinder 32 drives the entire rotating mechanism 2 to move vertically, thereby driving the pole group 5 to move in the vertical direction.

[0028] As Figure 1As shown in the figure, the translation mechanism 4 includes a translation motor 43, a gear 42 and a rack 41. The rack 41 is arranged on the equipment for manufacturing the battery, the translation motor 43 is arranged on the moving plate 31, the gear 42 is arranged at the output end of the translation motor 43 and is engaged with the rack 41. The translation motor 43 drives the gear 42 to move along the rack 41, thereby driving the entire moving mechanism 3 to move horizontally, so that the clamped electrode group 5 can also move horizontally.

[0029] As Figure 4 shown in the figure, both the left clamping plate 122 and the right clamping plate 132 are designed into a structure composed of an assembly plate 14 and clamping teeth 15. The assembly plate 14 is used for assembling on the bracket 11, and the clamping teeth 15 are used for directly clamping the electrode group 5. The clamping teeth 15 of one left clamping plate 122 and the clamping teeth 15 of a right clamping plate 132 adjacent to its right side form a clamping jaw.

[0030] As Figure 5 shown in the figure, there are a total of three clamping jaws, which can clamp three electrode groups 5 at the same time. Three left clamping plates 122 (a1, a2, a3) and three right clamping plates 132 (b3, b2, b1) are arranged parallel and staggered between two support plates 111. a1 and b3 form a clamping jaw, a2 and b2 form a clamping jaw, a3 and b1 form a clamping jaw. Between b3 and b2, they are connected by multiple right adjusting rods 133 that movably pass through a2. Between b2 and b1, they are connected by multiple right adjusting rods 133 that movably pass through a3. Between a3 and a2, they are connected by multiple left adjusting rods 123 that movably pass through b2. Between a2 and a1, they are connected by multiple left adjusting rods 123 that movably pass through b3. The left clamping plate 122 (a1) at the leftmost end is connected to the movable end of the left end cylinder 121, and the left end cylinder 121 drives all the left clamping plates 122 to move synchronously; the right clamping plate 132 (b1) at the rightmost end is connected to the movable end of the right end cylinder 131, and the right end cylinder 131 drives all the right clamping plates 132 to move synchronously. Through the cooperation of the left end cylinder 121 and the right end cylinder 131, all the clamping jaws are controlled to clamp or loosen synchronously. By changing the lengths of the left adjusting rods 123 and the right adjusting rods 133, the center distance between the clamped electrode groups 5 can be changed and the amplitude of loosening or clamping of each clamping jaw can be changed. Therefore, for different models and specifications of batteries, in their slotting process, it can be achieved by using this clamping device after changing the lengths of the left adjusting rods 123 and the right adjusting rods 133, thereby realizing the versatility of the equipment and avoiding the situation that different transfer devices are required for different specifications of batteries currently.

Those skilled in the relevant technical field can also make various changes or transformations without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions should also fall within the protection scope of the present utility model, and the protection scope of the present utility model should be defined by each claim.
