[0002] A battery is a device that can convert chemical energy into electrical energy. It consists of one or more electrochemical cells. During the battery manufacturing process, in order to facilitate the connection of the battery with other battery components or external circuits, a drill is usually used to drill holes on the positive and negative electrode columns of the battery.

[0003] At present, the method of drilling holes in the positive and negative electrode columns of batteries in some small-scale battery production sites mainly relies on workers holding the battery and placing it on the drilling table, and then using the bench drill to drill a hole in one electrode of the battery, and then rotating the battery to drill a hole in the other electrode.

When in use, the battery to be punched is placed on the top of the turntable 3, and one side of the battery is fitted with the fixing plate 5. When the turntable 3 rotates, the battery can be automatically clamped and fixed and released through the cooperation of the clamping mechanism 7 and the fixing plate 5. When the battery is clamped, it can prevent position displacement or shaking during the battery drilling process, which can not only ensure the consistency of the battery drilling operation, but also improve the safety of the staff. When the battery is released, it is convenient for the staff to remove the battery after the drilling is completed. A bracket 10 is bolted to one side of the operating table 1. The shape of the bracket 10 is an inverted L-shaped design, and one side of the upper side thereof extends to the top of the turntable 3. Hydraulic push rods 11 are installed on both sides above the bracket 10. The output end of the hydraulic push rod 11 is bolted to a mounting plate 12. The shape of the mounting plate 12 is an inverted L-shaped design. A moving block 14 is arranged on one side of the mounting plate 12 and is located above the turntable 3. The number of the moving blocks 14 is two and they are symmetrically distributed. The drilling head 16 can clamp the drill bit for drilling holes. A rotating column 15 is arranged above the moving block 14. The bottom end of the rotating column 15 passes through the bottom of the moving block 14 and is rotatably connected with its inner wall. The bottom end of the rotating column 15 is bolted to the top of the drilling head 16. When the two rotating columns 15 are rotating, the drilling head 16 below the moving block 14 can be driven to rotate synchronously. The output end of the hydraulic push rod 11 drives the mounting plate 12 to move downward, so that the drill bit of the drilling head 16 can drill holes on the positive and negative poles of the battery at the same time, thereby improving the efficiency of battery drilling. An adjusting mechanism 9 is arranged on the other side of the mounting plate 12.

[0028] The clamping mechanism 7 includes a rotating rod 71, which is located in the inner cavity of the through slot 6. Both ends of the rotating rod 71 are fixedly connected to the inner wall of the through slot 6. The surface of the rotating rod 71 is rotatably connected with a movable plate 72. The top of the movable plate 72 extends to the top of the turntable 3 through the through slot 6. The bottom of the movable plate 72 extends to the inner cavity of the operating table 1 through the through slot 6. A connecting rod 73 is bolted to the bottom of the movable plate 72. The bottom end of the connecting rod 73 is rotatably connected to a ball 74 through a bearing seat. A support seat 77 is bolted to the bottom of the inner wall of the operating table 1. The top of the support seat 77 is bolted to an outer arc plate 76 The outer arc plate 76 is used in conjunction with the ball 74. When the rotating turntable 3 drives the ball 74 to slide and contact the outer side of the outer arc plate 76, the ball 74 will drive the movable plate 72 through the connecting rod 73 to tilt in the through groove 6 with the rotating rod 71 as the center, so that the top of the movable plate 72 can be tilted close to the fixed plate 5. Under the cooperation of the inclined movable plate 72 and the fixed plate 5, the two sides of the automatic battery can be contacted and clamped to achieve the effect of fixing and limiting it, preventing the drilling head 16 from accidentally shaking the battery during the drilling process, which can improve the battery drilling The accuracy and consistency of the operation table 1 are improved, and there is no need to manually hold the battery for fixing, which can improve the safety of the staff. An inner arc plate 75 is bolted to one side of the inner wall of the operation table 1. The inner arc plate 75 is used in conjunction with the ball 74. When the rotating turntable 3 drives the ball 74 to slide in contact with the inner side of the inner arc plate 75, the ball 74 can drive the movable plate 72 through the connecting rod 73 to tilt around the rotating rod 71 in the through groove 6, so that the top of the movable plate 72 tilts away from the fixed plate 5, and then the clamping effect on both sides of the battery can be automatically released, so that the staff can easily fix the battery. When the battery is removed, the ball 74 connected to the connecting rod 73 by the turntable 3 will roll and slide on the surfaces of the inner arc plate 75 and the outer arc plate 76. This can improve the stability of the movable plate 72 in clamping the battery. Rubber pads 17 are provided on the sides facing each other of the movable plate 72 and the fixed plate 5. The rubber pads 17 have good elasticity and friction. When the rubber pads 17 are in contact with and clamped on the side of the battery, they will produce a certain elastic deformation, which can not only improve the fit between them and the side of the battery, but also enhance the friction when clamping the battery.

[0029] The adjusting mechanism 9 includes a bidirectional screw 91, which is located on the inner side of the mounting plate 12. One end of the bidirectional screw 91 is rotatably connected to a support plate through a bearing seat. The support plate of the bidirectional screw 91 is fixedly connected to the surface of the mounting plate 12. The surface of the bidirectional screw 91 is threadedly connected to a slider 92. The number of the sliders 92 is two and they are symmetrically distributed. A slide groove 96 is provided on the surface of the mounting plate 12. The slider 92 is slidably connected to the inner wall of the slide groove 96. One side of the slider 92 extends to the outer side of the mounting plate 12 through the slide groove 96. One side of the slider 92 is bolted to the moving block 14. When When the bidirectional screw 91 rotates, the two sliders 92 can move toward or away from each other along the surface of the bidirectional screw 91 through the sliding connection between the slider 92 and the slide groove 96, so that the two moving blocks 14 can be driven by the slider 92 to move toward or away from each other, thereby adjusting the distance between the two drilling heads 16, so that the spacing of the drilling heads 16 can be adapted to match the distance between the positive and negative poles of batteries of different sizes, thereby improving the versatility and flexible applicability of the device. The surface of the mounting plate 12 is bolted with a mounting shell 93, and the other end of the bidirectional screw 91 penetrates the mounting shell 93. The inner cavity of the two-way screw 91 is fixed to each other through a bearing at the penetration point, the other end of the two-way screw 91 is bolted with a worm wheel 95, and the upper surface of the worm wheel 95 is meshed with a worm 94, one end of the worm 94 is rotatably connected to the inner wall of the mounting shell 93 through a bearing, and the other end of the worm 94 penetrates to the outside of the mounting shell 93 and is fixed to each other through a bearing at the penetration point, and the other end of the worm 94 is bolted with a rotating handle, and by rotating the handle of the worm 94, the worm 94 can be meshed to drive the worm wheel 95 to rotate, and the worm wheel 95 can drive the two-way screw 91 to rotate. The meshing rotation between them has a self-locking effect, which can prevent the bidirectional screw 91 from rotating accidentally, so that the position of the sliding block 92 driving the moving block 14 to move can remain stable, and thus the stability of the position after the drilling head 16 spacing is adjusted can be guaranteed. A scale line 18 is provided on one side of the mounting plate 12 and below the slide groove 96. The scale line 18 is used in conjunction with the moving block 14. When the spacing of the drilling heads 16 is adjusted, the moving distance of the moving block 14 on the scale line 18 is referred to, so that the spacing of the drilling heads 16 can be adjusted quickly and accurately.

[0030] The transmission mechanism 8 includes a spline shaft 81, one end of the spline shaft 81 is bolted to the output shaft of the driving motor 13, and the other end of the spline shaft 81 is fixedly connected to the mounting plate 12 through a rotatably connected support plate. The surface of the spline shaft 81 is slidably connected with a spline sleeve 82, and the number of spline sleeves 82 is two. The surface of the spline sleeve 82 is bolted to a first bevel tooth 83, and the top end of the rotating column 15 is bolted to a second bevel tooth 84. The first bevel tooth 83 and the second bevel tooth 84 are meshed with each other. When the driving motor 13 provides power to rotate the spline shaft 81, the spline sleeve 82 and the first bevel tooth 83 can be driven to rotate to mesh with the second bevel tooth 84, thereby providing power for the rotating column 15 to rotate, so that the two drilling heads 16 can be electrically connected to the electric drive. The positive and negative poles of the battery are opened, and accordingly, a driving motor 13 can provide rotational power to the two drilling heads 16, which can reduce the cost of use and reduce energy consumption. The surface of the rotating column 15 is rotatably connected with an L-shaped connecting plate 85 through a bearing, and the other side of the L-shaped connecting plate 85 is rotatably connected to the surface of the spline sleeve 82 through a bearing. After the distance between the drilling heads 16 is adjusted, the spline sleeve 82 can slide along the surface of the spline shaft 81 through the connection setting between the L-shaped connecting plate 85, the moving block 14 and the spline sleeve 82, so that the first bevel gear 83 and the second bevel gear 84 can always maintain a stable meshing connection relationship, thereby being able to adapt to providing rotational power to the rotating columns 15 with different spacings.

[0031] It is worth noting that the drilling head 16 proposed in the technical solution is a prior art, which can clamp the drill bit for drilling operations, and its working principle and beneficial effects when used are not described in detail here.

[0032] Working principle: first, place the battery to be punched on the turntable 3, and fit the side of the battery with the fixed plate 5, then start the stepper motor 4 to drive the support column 2 and the turntable 3 to rotate, which can drive the ball 74 to rotate and contact the outer side of the outer arc plate 76. In this process, the ball 74 drives the movable plate 72 to tilt with the rotating rod 71 as the center through the connecting rod 73, so that the top of the movable plate 72 can be tilted toward the fixed plate 5, which can clamp and fix the two sides of the automatic battery, effectively preventing the battery from shaking during punching. When the turntable 3 drives the clamped battery to move to the bottom of the drilling head 16, the stepper motor 4 will temporarily stop running, and then start the drive motor 13 to drive the spline shaft 81, the spline sleeve 82 and the first bevel gear 83 to rotate, which can mesh the second bevel gear 84 to provide rotational power for the rotating column 15, so that the two drilling heads 16 rotate, and then the hydraulic push rod 11 drives the mounting plate 12 to descend, so that the drill bit of the drilling head 16 can drill holes in the positive and negative poles of the battery at the same time. The efficiency of the punching operation can be improved accordingly. When the punching is completed, the stepper motor 4 is started again to allow the punched battery to rotate with the turntable 3 to the other side. The turntable 3 will drive the ball 74 to contact the inner side of the inner arc plate 75, so that the top of the movable plate 72 can be tilted in the opposite direction away from the fixed plate 5. At this time, the clamping of the battery can be automatically released so that the battery after the punching is removed. When it is necessary to adjust the spacing between the two drilling heads 16, the worm 94 is first rotated by the handle to engage the worm wheel 95, so that the worm wheel 95 drives the bidirectional screw 91 to rotate, so that the slider 92 drives the moving block 14 to move toward or away from each other through the slide groove 96, so that the spacing between the two drilling heads 16 can be adjusted, so that it can adapt to the drilling of batteries of different sizes, thereby improving the flexibility and adaptability of the device. When adjusting the spacing between the drilling heads 16, the spline sleeve 82 can slide along the surface of the spline shaft 81 through the connection of the L-shaped connecting plate 85, so that the first bevel gear 83 and the second bevel gear 84 can always remain engaged.
