Description

Technical Field

[0001] This utility model relates to the field of storage battery production technology, specifically to an automatic electrode cap removal device. Background Technology

[0002] In the field of battery manufacturing, to improve the volumetric energy density of batteries, the busbars within each cell of the battery casing are designed as a direct-connection structure to enhance space utilization. This busbar needs to be completely immersed in an adhesive bath for sealing, and external terminals extend directly from its surface. The adhesive sealing process is performed simultaneously during the terminal assembly stage. The cap-shaped cover (terminal cap) covering the top of the terminal serves as a temporary protective structure and needs to be removed after the adhesive has cured to allow for subsequent welding of terminals to form the positive and negative output terminals of the battery.

[0003] Currently, the removal of terminal caps mainly relies on manual operation. Workers must use handheld tools such as pneumatic wrenches, custom-made pliers, or pneumatic screwdrivers to individually unscrew and remove the caps. This manual operation is labor-intensive, requiring workers to repeat high-frequency alignment and tightening actions over long periods, easily leading to fatigue. The removal efficiency is low, and it's difficult to guarantee the alignment angle or uniformity of force applied during manual removal, easily causing damage to the terminal caps and affecting subsequent welding yield. This manual, individual disassembly method has a low degree of automation, severely restricting the production efficiency of batteries. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic terminal cap removal device that can replace manual labor in automatically removing terminal caps, reducing labor consumption, ensuring high stability in removal, effectively improving removal efficiency, and thus improving the production efficiency of storage batteries.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic electrode cap removal device, comprising a conveyor belt, an interception component arranged on the conveying path of the conveyor belt, a removal mechanism above the interception component, the removal mechanism comprising a lifting plate, two snap-fit ​​screwing cylinders corresponding one-to-one with the two electrode caps on the battery after the cup is intercepted, and a driving component for driving the snap-fit ​​screwing cylinders to rotate, two fixed plates above the lifting plate, two top rods coaxially arranged with the two snap-fit ​​screwing cylinders respectively on the lower end surface of the fixed plate, and clearance holes for the top rods to pass through the lifting plate. When the lifting plate rises to a preset height, the lower end of the top rod extends into the inner cavity of the snap-fit ​​screwing cylinder.

[0006] A further improvement of this utility model is that the driving component includes a motor disposed between two snap-fit ​​screw cylinders, and two drive sprockets are coaxially spaced on the output shaft of the motor. Driven sprockets are fixed on the outer periphery of the two snap-fit ​​screw cylinders respectively, and each drive sprocket is connected to the corresponding driven sprocket through a transmission chain.

[0007] A further improvement of this utility model is that the upstream of the unscrewing mechanism is provided with a waste guide plate that can be moved to the bottom of the locking cylinder, and the distance between the lower end of the waste guide plate and the conveyor belt conveying surface is greater than the height of the battery.

[0008] A further improvement of this utility model is that a collection cylinder and a waste bin are provided on one side of the conveyor belt. The extension and retraction direction of the collection cylinder is consistent with the length direction of the conveyor belt. The waste guide plate is inclinedly fixed on the extension and retraction end of the collection cylinder, and the lowest end of the waste guide plate is located above the opening of the waste bin.

[0009] A further improvement of this utility model is that the interception component includes a fixed clamping plate disposed on one side above the conveyor belt and a movable clamping plate on the other side that can move along the width direction of the conveyor belt, and a clamping space is formed between the movable clamping plate and the fixed clamping plate.

[0010] A further improvement of this utility model is that the movable clamping plate includes a clamping part arranged along the conveying direction of the conveyor belt and an intercepting part arranged on the clamping part. The length direction of the intercepting part is perpendicular to the length direction of the clamping part and it is located on the conveying path of the conveyor belt.

[0011] A further improvement of this utility model is that the bottom guide port of the snap-fit ​​cylinder is provided with a chamfer on the outer periphery for guiding the pole cap.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention, through the cooperation of a conveyor belt, an interception component, and a screw-off mechanism, can replace manual labor in removing terminal caps, achieving automated removal of terminal caps, reducing labor consumption, ensuring high stability in screw-off, effectively improving screw-off efficiency, and thus increasing the production efficiency of batteries.

[0014] In this invention, the snap-fit ​​screwing cylinder is designed to be raised and lowered to snap onto the pole cap. Through the cooperation of the lifting plate and the fixed plate, after the screwing is removed, the snap-fit ​​screwing cylinder rises to the designated position and the pole cap inside is pushed out by the fixed top rod. This process can be achieved by the lowering and resetting of the snap-fit ​​screwing cylinder, without the need for an additional cylinder or motor to drive the top rod to extend or retract.

[0015] The two snap-fit ​​screw-on cylinders of this utility model correspond one-to-one with the terminal caps, which can handle both terminal caps of the battery at the same time, and are driven by the same power source, thus improving the synchronicity of removal.

[0016] The waste guide plate of this utility model moves to the bottom of the locking cylinder under the drive of the collection cylinder. It uses gravity and tilt angle to make the waste slide down, avoiding it from falling into the gap between the conveyor belt and the battery and causing jamming or scratching the battery surface. The distance between the guide plate and the conveying surface is greater than the height of the battery, ensuring that there is no interference when the battery passes through. The waste guide plate is precisely switched between the screwing position and the avoidance position by the collection cylinder, and it can cooperate with the push rod to collect the terminal caps pushed out.

[0017] The fixed clamping plate of this invention uses one side as a reference, while the movable clamping plate moves along the width of the conveyor belt to clamp the battery. The intercepting part intercepts the battery, improving the stability of the clamping and ensuring that the snap-fit ​​screw cylinder and the terminal cap are accurately aligned.

Detailed Implementation

[0023] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1: Combination Figures 1-4It is known that an automatic pole cap removal device includes a conveyor belt 1, an interception component is provided on the conveying path of the conveyor belt 1, and a removal mechanism is provided above the interception component. The removal mechanism includes a lifting plate 2, and two snap-fit ​​screwing cylinders 3 corresponding to the two pole caps on the battery after the cup is intercepted are rotatably connected to the lower end face of the lifting plate 2, as well as a driving component for driving the snap-fit ​​screwing cylinders 3 to rotate. A fixing plate 4 is provided above the lifting plate 2, and two top rods 5 are vertically provided on the lower end face of the fixing plate 4, which are coaxially arranged with the two snap-fit ​​screwing cylinders 3 respectively. The lifting plate 2 has a clearance hole for the top rods 5 to pass through. When the lifting plate 2 rises to a preset height, the lower end of the top rod 5 extends into the inner cavity of the snap-fit ​​screwing cylinder 3.

[0025] Preferably, the unscrewing mechanism includes a vertical plate mounted above the conveyor belt 1 via a bracket. A gap is provided between the lower end of the vertical plate and the conveyor belt 1 to facilitate battery passage. A slide rail is vertically mounted on the surface of the vertical plate. A lifting plate 2 is slidably connected to the vertical plate via the slide rail. A fixed plate 4 is horizontally fixed to the surface of the vertical plate and located above the lifting plate 2. A pressing cylinder is fixedly mounted on the fixed plate 4. The telescopic end of the pressing cylinder points vertically downwards, and the fixed plate 4 has a through-hole to allow its telescopic end to pass through. The telescopic end of the pressing cylinder passes through the fixed plate 4 and connects to the lifting plate 2, thereby controlling the lifting and lowering of the lifting plate 2. After unscrewing the terminal cap, the pressing cylinder drives the locking cylinder 3 to rise a certain height to allow the battery to move with the conveyor belt 1. After the battery has moved away, the pressing cylinder drives the locking cylinder 3 to continue rising, causing the lower end of the push rod 5 to extend into the inner cavity of the locking cylinder 3. The timing of the push rod 5 pushing out the waste terminal cap can be controlled as needed.

[0026] The driving component includes a motor 6 disposed between two snap-fit ​​screw cylinders 3. Two drive sprockets 7 are coaxially spaced on the output shaft of the motor 6. Driven sprockets 8 are fixed on the outer periphery of the two snap-fit ​​screw cylinders 3 respectively. Each drive sprocket 7 is connected to the corresponding driven sprocket 8 through a transmission chain 9.

[0027] Optionally, the motor 6 is fixedly mounted on the upper end of the lifting plate 2. The lifting plate 2 has a through-hole for the output shaft of the motor 6 to pass through. After passing through the through-hole, the output shaft of the motor 6 is connected to the two locking cylinders 3 for transmission. Further optionally, the telescopic end shell of the pressing cylinder is directly connected to the housing of the motor 6. By driving the motor 6 to move, the lifting plate 2 is moved in turn.

[0028] The upstream of the unscrewing mechanism is a waste guide plate 10 that can be moved to the bottom of the snap-fit ​​screwing cylinder 3. The distance between the lower end of the waste guide plate 10 and the conveying surface of the conveyor belt 1 is greater than the height of the battery.

[0029] A collection cylinder 11 and a waste bin 12 are provided on one side of the conveyor belt 1. The extension and retraction direction of the collection cylinder 11 is consistent with the length direction of the conveyor belt 1. A waste guide plate 10 is inclinedly fixed on the extension end of the collection cylinder 11, and the lowest end of the waste guide plate 10 is located above the opening of the waste bin 12. The waste guide plate 10, the collection cylinder 11, and the waste bin 12 constitute a waste collection mechanism. Preferably, the collection cylinder 11 is located on one side of the conveyor belt. The waste collection mechanism also includes a support rod located on the other side of the conveyor belt 1. One end of the waste guide plate 10 rests on the support rod and slides along its length direction, thereby supporting the waste guide plate 10 through the support rod.

[0030] The snap-fit ​​screwdriver 3 is a conventional screwdriver for removing the terminal cap in the prior art, and its inner opening is interference-fitted with the terminal cap. Preferably, the bottom guide opening of the snap-fit ​​screwdriver 3 has a chamfer on its outer periphery for guiding the terminal cap.

[0031] The interception assembly includes a fixed clamping plate 13 disposed on one side above the conveyor belt 1 and a movable clamping plate 14 on the other side that can move along the width direction of the conveyor belt 1, forming a clamping space between the movable clamping plate 14 and the fixed clamping plate 13. A clamping cylinder is provided on the side of the movable clamping plate away from the fixed clamping plate 13 to drive its movement, and a proximity sensor is provided on one side of the clamping cylinder to detect whether the battery has reached a predetermined position.

[0032] The moving clamp 14 includes a clamping part 15 disposed along the conveying direction of the conveyor belt 1 and an intercepting part 16 disposed on the clamping part 15. The length direction of the intercepting part 16 is perpendicular to the length direction of the clamping part 15 and it is located on the conveying path of the conveyor belt 1. Preferably, the intercepting part 16 is disposed at one end of the clamping part 15, and the battery is intercepted by the intercepting part 16 after moving to one side of the clamping part 15. The length of the intercepting part 16 is shorter than the width of the battery housing, ensuring that the battery housing can be stably clamped by the passive clamp and the fixed clamp.

[0033] The working principle of the automatic pole cap removal device provided by the utility model is as follows:

[0034] During operation, the battery is continuously conveyed along a set path by the conveyor belt 1. When it reaches the preset station, the moving clamp 14 of the interception component extends, clamping the battery casing laterally through the clamping part 15 and limiting it longitudinally through the interception part 16, achieving precise fixation. Subsequently, the lifting plate 2 drives the two snap-fit ​​screwing cylinders 3 to descend, and their bottom chamfered edges guide the terminal caps to align and snap together. The motor 6 synchronously drives the two snap-fit ​​screwing cylinders 3 to rotate through the double drive sprockets 7 and the transmission chain 9, simultaneously unscrewing the double terminal caps. After unscrewing is completed, the lifting plate 2 rises, and the moving clamp 14 resets to release the clamp. The conveyor belt 1 continues to transport the processed batteries to the next process; the collecting cylinder 11 retracts, causing the waste guide plate 10 to move to below the clamping screwing cylinder 3. When the lifting plate 2 rises to the preset height, the top rod 5 of the fixing plate 4 inserts into the inner cavity of the clamping screwing cylinder 3, pushing out the residual terminal cap. The inclined plate surface of the waste guide plate 10 receives the fallen terminal cap and guides it to slide into the waste bin 12. Then the collecting cylinder 11 extends, causing the waste guide plate 10 to move, switching between the screwing position and the avoidance position to facilitate the screwing operation of the next battery.
