Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 to 3 and fig. 6, the circulation device of the electrolyte filling machine for the square aluminum-shell battery is mainly composed of a guide rail mechanism 10, and the whole guide rail mechanism 10 is in a squared shape in a plan view. The guide rail structure comprises a mounting seat 11, an anti-collision strip 12 and universal wheels 13, wherein the mounting seat 11 forms transverse and vertical edges of a nine-square grid shape in the guide rail mechanism 10, the transverse and vertical edges are stably connected with each other, the anti-collision strip 12 is arranged on the outer side edge of the mounting seat 11, and the anti-collision strip 12 prevents a battery clamp 30 circulating on the guide rail mechanism 10 from impacting the mounting seat 11 to cause damage to the battery clamp 30; the universal wheels 13 are uniformly distributed on the upper end surface of the mounting seat 11, and the universal wheels 13 enable the battery clamp 30 to slide at the bottom during circulation, so that the moving resistance is reduced.

Set up 4 drag hook mechanism 20 in guide rail mechanism 10's bottom, drag hook mechanism 20 is arranged in guide rail mechanism 10 upper and lower, left and right end respectively, and drag hook mechanism 20 of upper end drives battery anchor clamps 30 and moves left, and drag hook mechanism 20 of left end drives battery anchor clamps 30 and moves down, and drag hook mechanism 20 of lower extreme drives battery anchor clamps 30 and moves right, and drag hook mechanism 20 of right-hand member drives battery anchor clamps 30 and moves up. Thus, the four hook mechanisms 20 effect a circulation of the battery holder 30 on the rail mechanism 10. Wherein, the direction of circulation can reverse according to actual demand and set up.

As shown in fig. 4 and 5, the retractor mechanism 20 mainly includes a retractor assembly 22, a synchronous belt 24, a guide plate 23 and a driving motor 21, the retractor assembly 22 is fixedly connected with the synchronous belt 24, the synchronous belt 24 is limited in the guide plate 23, the driving motor 21 drives the synchronous belt 24 and the retractor assembly 22 to reciprocate through the synchronous wheel 25, pressing wheels 26 for clamping the synchronous belt 24 are arranged on two sides of the synchronous wheel 25, and the pressing wheels 26 press and attach the synchronous belt 24 to the synchronous wheel 25. The synchronizing wheel 25 and the pressure wheel 26 are arranged in a mounting frame 28, and the mounting frame 28 fixedly mounts the entire retractor mechanism 20. As shown in fig. 8, a hook groove 32 adapted to the hook assembly 22 is formed at the bottom of the battery clamp 30, and the hook assembly 22 is sunk into the hook groove 32, so that the hook mechanism 20 can drive the battery clamp 30 to move along the circulation direction.

In the hook mechanism 20, the inductor 27 is further arranged, the inductor 27 is arranged at the position, corresponding to the guide plate 23, of the hook groove 32, the inductor 27 is used for inducing the position of the hook assembly 22, when the hook mechanism 20 needs to rotate the next battery clamp 30, the driving motor 21 returns the hook assembly 22, the inductor 27 induces the hook assembly 22 to reach the position, corresponding to the hook groove 32, the inductor 27 feeds information back to the driving motor 21, the driving motor 21 stops current rotation, and the hook assembly 22 and the battery clamp 30 connected at present can be driven reversely to move and rotate.

In order to ensure that the retractor assembly 22 can be synchronously locked and unlocked with the battery clamp 30 during the reciprocating motion, the retractor assembly 22 comprises a retractor seat 221, a retractor 222 and a spring 223. The draw hook seat 221 is fixedly connected with the synchronous belt 24, the draw hook seat 221 is connected with the draw hook seat 221 through a rivet, the spring 223 is connected between the draw hook seat 221 and the draw hook 222, and the draw hook 222 is ejected out by the spring 223; when the hook 222 is retained in the hook groove 32, if the hook assembly 22 moves toward the hook opening, the hook assembly 22 drives the battery clamp 30 to move, and if the hook assembly 22 moves toward the hook opening, the hook 222 slides out of the hook groove 32.

As shown in fig. 2 and 7, the circulation device of the prismatic aluminum-shell battery electrolyte filling machine further comprises a positioning mechanism 40. In the process of circulation of the battery clamp 30, the hook mechanism 20 can be locked and unlocked with the battery clamp 30 through reciprocating motion. When unlocking, the draw hook assembly 22 moves to the next battery clamp 30 to be transferred, the draw hook assembly 22 moves towards the opposite direction of the hook opening, and interaction force exists between the draw hook and the draw hook groove 32, so that the current battery clamp 30 is easily pushed back. Therefore, the positioning mechanism 40 is correspondingly arranged at the bottom end of the guide rail mechanism 10 and beside the hook mechanism 20, and the positioning hole 31 is correspondingly arranged at the bottom of the battery clamp 30. The positioning mechanism 40 comprises a positioning cylinder 41 and a positioning pin 42, the positioning cylinder 41 is connected with the positioning pin 42, the positioning cylinder 41 drives the positioning pin 42 to extend or retract, and the positioning pin 42 is matched with the positioning hole 31 so as to lock or unlock the position of the battery clamp 30.

As shown in fig. 3 and 9, the circulation device of the prismatic aluminum-shell battery electrolyte filling machine further comprises a buffer mechanism 50. The universal wheels 13 are adopted on the guide rail mechanism 10 to reduce the friction resistance during movement, and when the battery clamp 30 rotates along with the guide rail mechanism 10 and moves to a specified position, the battery clamp 30 continues to move and impacts the bumper strip 12 of the guide rail mechanism 10 due to the inertia effect. While the bumper strip 12 protects the battery clamp 30 and the track mechanism 10, the battery clamp 30 will rebound back in response to the reaction force, causing an out-of-position condition. Therefore, it is necessary to arrange the buffer mechanisms 50 on the outer sides of the rail mechanisms 10 at the ends of the battery clamps 304 in the moving direction, respectively, where the buffer mechanisms 50 include buffer cylinders 51, buffer pads 52, and buffer mounting plates 53, the buffer cylinders 51 are connected to the buffer pads 52, the buffer pads 52 are used for buffering the battery clamps 30 near the outer sides of the rail mechanisms 10, the buffer cylinders 51 are connected to the buffer mounting plates 53, and the buffer mounting plates 53 are connected to the outer sides of the rail mechanisms 10. When the battery holder 30 moves to the near-end position, the cushion 52 of the cushion mechanism 50 contacts the battery holder 30 and slows down the power of the battery holder 30, so that the battery holder 30 slowly reaches the end position of this movement, avoiding the above-mentioned bounce problem.

The battery clamps 30 are arranged on the guide rail mechanism 10 in sequence, 1 ~ 3 transfer vacant positions of the battery clamps 30 are required to be reserved in the guide rail mechanism 10 (the positions of the guide rail mechanism 10 occupied by the transfer vacant positions are equal to those of the battery clamps 30), the transfer vacant positions cannot be connected, and the battery clamps 30 are required to be separated to ensure the smooth flow of the battery clamps 30. the description is made by using fig. 1 and taking an example of the flow starting of the left-end drag hook mechanism 20 in the drawing, assuming that the lower left corner in fig. 1 is the transfer vacant position, the upper end of the transfer vacant position at the lower left corner is continuously full of the battery clamps 30, and the left-end drag hook mechanism 20 is required to move the battery clamps 30 downwards by one transfer vacant position.

Step one, a positioning pin 42 in a positioning mechanism 40 at the left end extends out to be locked with a positioning hole 31 of a currently corresponding battery clamp 30, a hook assembly 22 in a hook mechanism 20 at the left end moves upwards and moves to a hook groove 32 of the battery clamp 30 at the uppermost end, and after a sensor 27 senses that the hook assembly 22 reaches a target position, the hook mechanism 20 stops moving the hook assembly 22; step two, the positioning pin 42 of the positioning mechanism 40 is removed from the positioning hole 31, the hook mechanism 20 drives the hooked battery clamp 30 to move downwards, and other battery clamps 30 are pushed and synchronously move downwards; step three, when the battery clamp moves to the position close to the tail end, the cushion pad 52 of the buffer mechanism 50 at the tail end is contacted with the battery clamp 30, the cushion pad 52 slows down the moving speed of the battery clamp 30, and the battery clamp 30 slowly reaches the tail end position; and step four, the positioning pin 42 of the positioning mechanism 40 extends again to be locked with the positioning hole 31, so that the battery clamp 30 is prevented from rebounding.

After the above steps are completed, the transfer vacancies change from the bottom left corner to the top left corner. The upper end of the drag hook mechanism 20 adopts the same operation flow to move the battery clamp 30, and in turn, the right end and the lower end of the drag hook mechanism 20 can realize the movement of the battery clamp 30 in the corresponding direction in the same way, and a circulating battery clamp 30 circulation is formed on the whole guide rail mechanism 10.

The above examples are intended to illustrate rather than to limit the invention, and all equivalent changes and modifications made by the methods described in the claims of the present invention are intended to be included within the scope of the present invention.
