Description

Technical Field

[0001] The invention relates to the technical field of battery cover plate production and processing equipment, and in particular to a welding device for a minimalist cover plate. Background Art

[0002] The minimalist battery cover is mainly composed of positive and negative poles and explosion-proof devices welded together. The minimalist battery cover can effectively increase the flow area of ​​the contact surface between the boss and the conductive sheet, reduce the overcurrent, and reduce the probability of the flip sheet being melted, thereby effectively reducing the risk of fire or explosion of the power battery, and greatly improving the safety performance of the power battery. In the prior art, workers place the positive and negative poles on the minimalist cover, and then weld and fix the positive and negative poles on the minimalist cover by laser welding technology. This method of manually welding and fixing the positive and negative poles on the minimalist cover with the positive and negative poles installed by laser welding technology will cause the following problems:

[0003] In the prior art, workers may tilt the minimalist cover when placing it on the work platform, causing the placement of the minimalist cover to deviate from the laser working area, thereby causing the welding positions of the positive and negative poles on the minimalist cover to deviate, resulting in unstable welding of the poles, which will affect the service life of the minimalist cover during subsequent use.

[0004] In the prior art, a minimalist cover plate with positive and negative poles installed is placed in the laser operation area of ​​the laser device, and the positive and negative poles are fixed on the minimalist cover plate by pressing the pole to ensure the stability of the laser beam when welding the positive and negative poles. However, the position of the pressing pole will block the laser device and hinder the laser device from emitting lasers, which will affect the complete welding and fixing of the outer circumference of the positive and negative poles on the minimalist cover plate. When the laser device reaches the position of the pressing pole, the worker needs to move the pressing pole to the area where the welding is completed so that the laser can continue to work until the outer circumference of the positive and negative poles is welded and fixed. When the worker manually moves the pressing pole, the laser will burn the worker's skin and damage the worker's health. In addition, during the welding process, the worker needs to pay attention to the position of the laser at all times and move the pressing pole in time to ensure the continuous welding operation, which increases the labor intensity of the worker and reduces the safety of the worker's working environment.

DETAILED DESCRIPTION

[0025] like Figure 1 and Figure 2 As shown, a welding device for a minimalist cover plate of the present invention comprises a working platform placed on the ground, a welding mechanism 1, a feeding mechanism 3 and a clamp 4 arranged on the working platform.

[0026] like Figure 1 and Figure 2As shown, the feeding mechanism 3 is used to position and transfer the minimalist cover plate 2 with the positive and negative terminals 201 installed into the fixture 4 so that the welding mechanism 1 can weld and fix the positive and negative terminals 201 on the minimalist cover plate 2. The feeding mechanism 3 includes a slide rail 304 fixed on the working platform and distributed along the width direction of the working platform. A lead screw is arranged in the slide rail 304 along the length direction of the slide rail 304, and a slider 303 is slidably fitted on the lead screw. The slider 303 is in a U shape, and a nut that slidably cooperates with the lead screw is connected to the slider 303. The two side edges of the slider 303 are bent towards the opposite direction to form flanges that respectively slidably cooperate with the two side edges of the slide rail 304. A Z-shaped support plate 302 is fixedly installed on the upper edge outside the slider 303. The bottom plate at the lower end of the Z-shaped support plate 302 is fixed on the slider 303 by a plurality of bolts. The middle part of the support plate 302 is a straight plate distributed in the vertical direction. A reinforcing plate is arranged between the bottom plate and the straight plate to strengthen the connection between the bottom plate and the straight plate. The reinforcing plate is located on the other side of the bottom plate and the straight plate away from the fixture 4. One side edge of the reinforcing plate is fixed on the bottom plate, and the other side edge of the reinforcing plate is fixed on the straight plate.

[0027] As Figure 4 shown, the upper end of the support plate 302 is a flat plate distributed towards the fixture 4. A positioning plate 301 for fixing and positioning the minimalist cover plate 2 is arranged on the flat plate. The positioning plate 301 is located at the end of the flat plate close to the fixture 4. A positioning groove adapted to the shape of the minimalist cover plate 2 for placing the minimalist cover plate 2 with the positive and negative terminals 201 installed is formed on the positioning plate 301. The positioning groove can prevent the minimalist cover plate 2 placed in the positioning plate 301 by the worker from tilting. Positioning steps for keeping the minimalist cover plate 2 and the upper edge of the positioning plate 301 horizontal are formed on the inner sides of the two side edges of the positioning plate 301 located in the positioning groove. The setting of the positioning steps can make the minimalist cover plate 2 located in the positioning plate 301 and the upper edge of the positioning plate 301 be on the same horizontal plane to facilitate the welding of the welding mechanism 1. The lead screw is connected to a servo motor 305 for driving the lead screw to rotate. The servo motor 305 is used for the slider 303 to slide on the slide rail 304 as the lead screw rotates. The servo motor 305 can control the sliding distance of the slider 303 on the slide rail 304 so that the support plate 302 moves with the slider 303 until the minimalist cover plate 2 on the positioning plate 301 is located in the fixture 4, and moving the minimalist cover plate 2 into the fixture 4 facilitates the welding mechanism 1 to weld it.

[0028] As Figure 1As shown, the clamp 4 is used to clamp and fix the positive and negative poles 201 on the minimalist cover plate 2 transferred by the feeding mechanism 3 to the clamp 4 so that the welding mechanism 1 can weld and fix the positive and negative poles 201 on the minimalist cover plate 2. The clamp 4 includes a clamp bottom plate 405 that spans the top of the slide rail 304 and is distributed along the width direction of the slide rail 304. The clamp bottom plate 405 is distributed above the slide rail 304 in the horizontal direction, and vertical plates 407 that are distributed in the vertical direction and used to support the clamp bottom plate 405 above the slide rail 304 are respectively provided on the left and right sides of the clamp bottom plate 405. The two vertical plates 407 are respectively located below the clamp bottom plate 405 on the left and right sides of the slide rail 304. The upper sides of the two vertical plates 407 are respectively fitted with the lower edges of the clamp base plate 405 and the clamp base plate 405 is fixed to the vertical plates 407 on the corresponding sides by multiple bolts. The lower sides of the vertical plates 407 are respectively fixed to the working platforms on both sides of the slide rail 304 by multiple bolts to enhance the stability of the clamp 4.

[0029] like Figure 5 and Figure 6 As shown, a first movable mounting plate 404 distributed in the horizontal direction is provided on the upper side of the fixture bottom plate 405, the first movable mounting plate 404 is kept parallel to the fixture bottom plate 405 and is located directly above the fixture bottom plate 405, and a clamping cavity 421 is formed between the first movable mounting plate 404 and the fixture bottom plate 405, and the clamping cavity 421 is used to place and clamp and fix the minimalist cover plate 2 transferred by the feeding mechanism 3 to the fixture 4. A rectangular pressing notch 420 is symmetrically provided on the first movable mounting plate 404 for the welding mechanism 1 to weld and fix the corresponding side pole 201 on the minimalist cover plate 2, and arc notches 403 distributed in opposite directions are symmetrically provided on the first movable mounting plate 404 and the fixture bottom plate 405 located outside the corresponding pressing notch 420, and the center of the arc notch 403 coincides with the center of the pressing notch 420.

[0030] like Figure 4 and Figure 5 As shown, a second movable mounting plate 410 is provided on the lower side of the fixture bottom plate 405, which is distributed in the horizontal direction and fixedly connected to the first movable mounting plate 404. The second movable mounting plate 410 is parallel to the fixture bottom plate 405 and is located directly below the fixture bottom plate 405. A clamping chord arm 419 and a driving assembly for driving the clamping chord arm 419 to rotate in the corresponding side arc-shaped notch 403 are symmetrically provided on the second movable mounting plate 410. The upper end of the clamping chord arm 419 passes through the arc-shaped notch 403 provided on the fixture bottom plate 405 and the first movable mounting plate 404, respectively, and is connected to a supporting pressure column 417. The supporting pressure column 417 is located directly above the corresponding side downward pressure notch 420 and is used to resist the pole 201 installed on the minimalist cover plate 2.

[0031] The pressing string arm 419 is provided with a collar 422 for the sliding fit of the supporting pressure column 417. The upper end of the supporting pressure column 417 passes through the collar 422 and is in sliding fit with it. The lower end of the supporting pressure column 417 passing through the collar 422 abuts against the pole column 201. The shaft diameter of the lower end of the supporting pressure column 417 is larger than that of the upper end of the supporting pressure column 417, and the lower end of the supporting pressure column 417 forms an enlarged end for increasing the contact area with the pole column 201. A spring 418 for buffering the pressure of the supporting pressure column 417 against the corresponding side pole column 201 is provided between the lower end of the supporting pressure column 417 and the collar 422. The upper end of the spring 418 is fixed to the lower edge of the collar 422, and the lower end is fixedly connected to the upper edge of the enlarged end of the lower end of the supporting pressure column 417.

[0032] As Figure 1 and Figure 5 shown, the driving assembly is located at the upper edge of the second movable mounting plate 410. The driving assembly includes two racks 413 and a second air cylinder 416 for driving the sliding of the racks 413. The side edges of the two racks 413 that are flat face in opposite directions, and the side edges of the two racks 413 with teeth face away from each other. The second air cylinder 416 is provided with two slide bars 415 for the sliding fit of the racks 413 on the second air cylinder 416. The two slide bars 415 are symmetrically arranged on the upper side surface of the second air cylinder 416 and are respectively distributed along the length direction of the second air cylinder 416. The piston rod of the second air cylinder 416 is connected with a rack connecting plate 414 that is in sliding fit with the slide bars 415. The rack connecting plate 414 is located between the second air cylinder 416 and the rack 413. The lower side surface of the rack connecting plate 414 is provided with a chute for the sliding fit of the slide bars 415. The upper side surface of the rack connecting plate 414 is fixedly connected with the two racks 413. The rack connecting plate 414 drives the rack 413 to slide on the second air cylinder 416 as the piston rod of the second air cylinder 416 expands and contracts. On the left and right sides of the second air cylinder 416, there are respectively gears 411 connected to the corresponding side pressing string arms 419. The gears 411 are respectively meshed and matched with the corresponding side racks 413. The gears 411 rotate as the racks 413 slide on the second air cylinder 416. The rotation of the gears 411 will drive the corresponding side pressing string arms 419 to rotate in the arc-shaped notch 403 with the supporting pressure column 417 as the center. As the pressing string arm 419 rotates, the laser head in the welding mechanism 1 continues to weld until the corresponding side pole column 201 is completely welded and fixed on the minimalist cover plate 2. Below the gears 411, there are respectively gear rotating shaft seats 412 for supporting the gears 411 to enable the gears 411 to rotate in cooperation. The shape of the gear rotating shaft seat 412 is an inverted U shape. The outer planes of the U-shaped gear rotating shaft seats 412 are respectively fixedly connected with the corresponding side gears 411. The two side edges of the open end of the gear rotating shaft seat 412 are fixed on the second movable mounting plate 410, and the height of the gear rotating shaft seat 412 is such that the corresponding side gears 411 are respectively meshed with the corresponding side racks 413, and the rotation center of the gear 411 coincides with the center of the pole column 201.

[0033] Four guiding columns 409 vertically distributed in parallel are provided on the second movable mounting plate 410 at intervals, and the four guiding columns 409 are respectively located at the four corner positions of the second movable mounting plate 410. The lower ends of the guiding columns 409 are fixed on the second movable mounting plate 410, and the upper ends of the guiding columns 409 respectively pass through the through holes opened on the fixture bottom plate 405 and the first movable mounting plate 404 from bottom to top. A return spring 401 is provided at the upper end of the guiding column 409. The upper end of the return spring 401 is fixedly connected to the top end of the guiding column 409, and the lower end of the return spring 401 is fixed on the upper side surface of the first movable mounting plate 404. Linear bearings 402 through which the corresponding guiding columns 409 pass are respectively provided on the fixture bottom plate 405, and the holes in the linear bearings 402 are communicated with the through holes.

[0034] Notches are respectively opened on the left and right side edges of the second movable mounting plate 410 along the width direction of the second movable mounting plate 410, and inverted U-shaped top plates 406 are respectively provided on the second movable mounting plate 410 above the notches. As Figure 3 and Figure 5 shown, first cylinders 408 for driving the second movable mounting plate 410 and the first movable mounting plate 404 to lift and lower synchronously are respectively provided below the two side edges of the second movable mounting plate 410. The piston rods of the first cylinders 408 are in contact with the top plates 406 on the second movable mounting plate 410 so that when the piston rods of the first cylinders 408 extend, the second movable mounting plate 410 and the first movable mounting plate 404 are pushed to rise. The synchronous rise or fall of the second movable mounting plate 410 and the first movable mounting plate 404 can drive the support pressing column 417 to rise or fall along with the pressing string arm 419.

[0035] When the piston rods of the first cylinders 408 extend to push the second movable mounting plate 410 and the first movable mounting plate 404 to rise, the support pressing column 417 rises along with the pressing string arm 419 so that the feeding mechanism 3 sends the minimalist cover plate 2 into or out of the clamping cavity 421. When the piston rods of the first cylinders 408 retract to drive the second movable mounting plate 410 and the first movable mounting plate 404 to fall, the support pressing column 417 falls along with the pressing string arm 419 so that the support pressing column 417 abuts against the pole 201 to maintain the stability when the welding mechanism 1 welds and fixes the pole 201. Bases for supporting the first cylinders 408 are respectively provided below the first cylinders 408, and the size of the bases is larger than the cylinder bodies of the first cylinders 408 to maintain the stability of the first cylinders 408 on the second movable mounting plate 410.

[0036] The welding mechanism 1 is used to weld the pole 201 to the minimalist cover plate 2. The welding mechanism 1 is fixed on a three-axis mobile platform (not shown in the drawings, the three-axis mobile platform belongs to conventional technology and is not described here) and is located above the fixture 4 so that the welding mechanism 1 can be continuously moved along with the welding position of the positive and negative poles 201. The welding mechanism 1 includes a laser head distributed in the vertical direction just above the minimalist cover plate 2. The laser emitted by the laser head welds the positive and negative poles 201 to the minimalist cover plate 2.

[0037] The specific implementation of the present invention is as follows: First, the first cylinder 408 is started, and the first cylinder 408 pushes the second movable mounting plate 410 and the first movable mounting plate 404 to rise synchronously so that the support pressure column 417 rises with the compression string arm 419. Secondly, the worker places the minimalist cover plate 2 installed with the positive and negative poles 201 in the positioning plate 301 of the feeding mechanism 3. After the minimalist cover plate 2 is placed in the positioning plate 301, the servo motor 305 is started, and the slider 303 slides on the slide rail 304 toward the clamp 4 as the lead screw rotates until the minimalist cover plate 2 in the positioning plate 301 is placed in the clamping cavity 421. When the minimalist cover plate 2 is located in the clamping cavity 421, the first cylinder 408 is started, and the piston rod of the first cylinder 408 pushes the second movable mounting plate 410 and the first movable mounting plate 404 to descend synchronously and drives the supporting pressure column 417 to descend along with the descending of the clamping chord arm 419 and rest against the pole 201 on the minimalist cover plate 2 located in the clamping cavity 421, and the inner side edge of the pressing groove 420 cooperates with the outer periphery of the pole 201 so that the outer periphery of the pole 201 is fixed on the minimalist cover plate 2 through the welding mechanism 1.

[0038] The welding mechanism 1 is started and moves on the three-axis moving platform so that the laser head is located in the pressing notch 420. Figure 6 As shown, when the laser head starts welding from point a and rotates clockwise to point b, the second cylinder 416 is started, and the piston rod of the second cylinder 416 extends to make the rack 413 slide on the second cylinder 416 along with the rack connecting plate 414. At this time, the gear 411 meshing with the rack 413 rotates respectively. The compression chord arm 419 rotates and moves away in the arc groove 403 along with the rotation of the gear 411 to avoid blocking the welding mechanism 1. The laser head can continue to weld from point b to point a to complete a circle of welding on the outer periphery of the pole 201 so that the pole 201 is completely welded and fixed on the minimalist cover 2.

[0039] Finally, after the positive and negative poles 201 are welded and fixed on the minimalist cover plate 2, the first cylinder 408 is started and pushes the second movable mounting plate 410 and the first movable mounting plate 404 to rise, and the support pressure column 417 is loosened from the corresponding side pole 201 as the second movable mounting plate 410 rises. The servo motor 305 is started, and the minimalist cover plate 2 with the pole 201 welded and fixed in the positioning plate 301 moves out of the clamping cavity 421 as the slider 303 moves on the slide rail 304. After the slider 303 stops sliding, the worker can take out the minimalist cover plate 2 in the positioning plate 301. The welding and fixing of the pole 201 on the minimalist cover plate 2 is repeated in sequence.
