[0001] This utility model relates to the field of lead-acid battery processing technology, specifically to a deburring device for lead-acid battery tabs. Background Technology

[0002] Burrs are easily generated on the tabs of lead-acid batteries after stamping. If these burrs are not removed, they will affect the reliability of the battery's electrical connection and may even lead to safety hazards such as short circuits or overheating. Traditional deburring methods mostly use manual grinding or fixed tools, which have problems such as low efficiency, poor consistency, and easy damage to the tab body. Utility Model Content

[0003] To overcome the above deficiencies, this utility model provides a deburring device for lead-acid battery tabs that overcomes or at least partially solves the above technical problems.

[0004] This utility model is implemented as follows: This utility model provides a deburring device for lead-acid battery tabs, comprising: frame; A battery positioning fixture is used to fix a lead-acid battery and position the battery tabs in a preset processing position, and is mounted on the frame. The displacement mechanism is mounted on the frame; A composite grinding head assembly is mounted on the displacement mechanism and includes a second motor, a rotating shaft, and a burr removal head. The rotating shaft is fixed to the output end of the second motor, and the burr removal head is fixed to the free end of the rotating shaft. The burr removal head has a through groove, which is coaxial with the tab of the lead-acid battery, and a first abrasive layer is present in the through groove.

[0005] In one embodiment of this utility model, the inner wall of the burr cleaning head is provided with a groove, a spring is installed in the groove, the free end of the spring is fixedly connected to a cleaning block, and the inner wall of the cleaning block has a second abrasive layer.

[0006] In one embodiment of this utility model, the first abrasive layer is a cutting edge made of cemented carbide.

[0007] In one embodiment of this utility model, the second abrasive layer is a hard abrasive bristle embedded in the cleaning block.

[0008] In one embodiment of this utility model, the battery positioning fixture includes a positioning platform fixed on the surface of the frame. The surface of the positioning platform is provided with a clamping groove. A threaded rod is threadedly connected to the surface of the positioning platform. The threaded rod is composed of two threaded segments with opposite thread directions. Each threaded segment is threadedly connected with a clamping member. The clamping member is slidably connected in the clamping groove. An adjustment knob is fixedly connected to one end of the threaded rod.

[0009] In one embodiment of this utility model, a limiting plate is fixedly connected to the surface of the clamping member, and the limiting plate is perpendicular to the clamping member.

[0010] In one embodiment of this utility model, the displacement mechanism includes a first motor mounted on a frame, a lead screw fixedly connected to the output end of the first motor, a slide table threadedly connected to the outer wall of the lead screw, a guide rail fixedly connected to the surface of the frame, the slide table slidably connected to the guide rail, and a second motor fixed on the slide table.

[0011] The present invention provides a deburring device for lead-acid battery tabs, the beneficial effects of which include: 1. An overall structure of an automated deburring device is provided.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example

[0017] Reference Figures 1-6 This technical solution provides a deburring device for lead-acid battery tabs, which includes a frame 100, a battery positioning fixture 200, a displacement mechanism 300, and a composite grinding head assembly 400.

[0018] The battery positioning fixture 200 is used to fix the lead-acid battery and place the lead-acid battery tabs in a preset processing position, and the battery positioning fixture 200 is mounted on the frame 100.

[0019] The displacement mechanism 300 is mounted on the frame 100.

[0020] The composite grinding head assembly 400 is mounted on the displacement mechanism 300, and the composite grinding head assembly 400 includes a second motor 410, a rotating shaft 420 and a burr removal head 430. The rotating shaft 420 is fixed to the output end of the second motor 410, and the burr removal head 430 is fixed to the free end of the rotating shaft 420. The burr removal head 430 has a through groove 431, which is coaxial with the tab of the lead-acid battery. The through groove 431 has a first abrasive layer 440 inside.

[0021] It should be added that the first abrasive layer 440 is a cutting edge made of cemented carbide, which has the characteristics of high hardness and strong wear resistance. It can quickly cut burrs on the side of the electrode tab and maintain long-term stability, reducing the frequency of replacement and maintenance costs.

[0022] The output shaft of the first motor 310 is connected to the lead screw 320 via a coupling. The coupling is a diaphragm type (model such as JMⅡ-14), and the diaphragm material is 65Mn spring steel. During assembly, it is necessary to ensure that the two shafts are aligned to avoid transmission jamming.

[0023] The two ends of the threaded rod 230 are connected to the side wall of the positioning table 210 through deep groove ball bearings. The outer ring of the bearing is fixed to the inner wall of the positioning table through the bearing seat. The inner ring is interference-fitted with the threaded rod (interference amount 0.01-0.02mm). A sealing ring is installed on the outside of the bearing seat to prevent lead slag from entering and affecting the rotation of the threaded rod.

[0024] The limiting plate 260 and the clamping part 240 are connected by welding. The welding method is fillet welding with a weld leg height of 5mm. After welding, stress relief treatment is required (such as heat preservation at 200℃ for 2 hours). A reinforcing rib (thickness 3mm and width 15mm) is added to the end of the limiting plate away from the clamping part. The reinforcing rib is fixed to the limiting plate and the clamping part by spot welding to prevent the limiting plate from deforming under stress.

[0025] One end of the spring 450 is fixed to the bottom of the groove 432 by welding, and the other end is connected to the hanging hole on the side of the cleaning block 460 by a hook structure. The diameter of the hanging hole is larger than the diameter of the spring wire, and the spring's compression in its natural state is 2-3mm, ensuring that the cleaning block always has a preload in the direction of the tab. The first abrasive layer 440 is a cemented carbide cutting edge, which is fixed to the inner wall of the through groove 431 by brazing. The brazing filler metal is a copper-zinc alloy. The cutting edge fits snugly against the inner wall of the through groove. After welding, the cutting edge needs to be ground to ensure its sharpness. The first abrasive layer 440 is distributed axially along the through groove 431, with 3-4 evenly distributed circumferentially. The spacing between adjacent cutting edges is 90°-120° to ensure that burrs in the circumferential direction of the tab can be cut and removed. The end of the lead screw 320 away from the first motor is axially positioned by a thrust ball bearing, and the bearing housing is fixed on the frame 100 to ensure that the lead screw does not move axially.

[0026] This lead-acid battery tab deburring device provides an automated deburring system. The battery tabs are fixed to a preset position by a battery positioning clamp 200, and a displacement mechanism 300 drives a composite grinding head assembly 400 to move precisely, aligning the through-groove 431 of the deburring head 430 with the tab axis. The first abrasive layer 440 within the through-groove 431 efficiently removes burrs from the tab sidewalls. This structure achieves rapid positioning, automatic feeding, and efficient grinding, significantly improving deburring efficiency and consistency.

[0027] Reference Figures 1-6 Based on the same concept as in Embodiment 1 above, this embodiment also proposes that the inner wall of the burr cleaning head 430 is provided with a groove 432, a spring 450 is installed in the groove 432, the free end of the spring 450 is fixedly connected to a cleaning block 460, and the inner wall of the cleaning block 460 has a second abrasive layer 470.

[0028] It should be noted that the second abrasive layer 470 consists of hard abrasive bristles embedded in the cleaning block 460. It has flexible contact characteristics, which can avoid excessive wear on the electrode body when cleaning the thread root on the side of the electrode, while ensuring the burr removal effect and improving processing safety and quality.

[0029] A groove 432, a spring 450, and a cleaning block 460 are added to the inner wall of the burr removal head 430. The second abrasive layer 470 on the inner wall of the cleaning block 460 adaptively presses the side of the electrode tab under the action of the spring 450, which is beneficial for removing burrs at the root of the electrode tab thread.

[0030] The first abrasive layer 440 on the deburring head 430 is a rigid cleaning part, responsible for efficiently removing large burrs and flash from the outer wall of the tab post. The spring 450, the cleaning block 460, and the second abrasive layer 470 combine to form a flexible cleaning part. When it rotates at high speed, the flexible bristles will bend and deform, actively drilling into the groove of the thread to grind and polish the burrs at the root. The combination of rigid and flexible cleaning completes the cleaning from macro burrs to micro burrs in one go, especially ensuring the cleanliness of the thread root.

[0031] Specifically, refer to Figure 5 The battery positioning fixture 200 includes a positioning platform 210 fixed on the surface of the frame 100. The surface of the positioning platform 210 is provided with a clamping groove 220. A threaded rod 230 is threadedly connected to the surface of the positioning platform 210. The threaded rod 230 is composed of two threaded sections with opposite thread directions. Each threaded section is threadedly connected with a clamping member 240. The clamping member 240 is slidably connected in the clamping groove 220. An adjustment knob 250 is fixedly connected to one end of the threaded rod 230.

[0032] The battery positioning fixture 200 achieves rapid clamping and centering of the battery through the positioning platform 210, clamping groove 220, bidirectional threaded rod 230 and clamping member 240. The adjustment knob 250 facilitates operation, and the clamping member 240 slides in the clamping groove 220 to ensure stable clamping. It is suitable for batteries of different sizes, improving the versatility and ease of operation of the device.

[0033] Specifically, a limiting plate 260 is fixedly connected to the surface of the clamping member 240, and the limiting plate 260 is perpendicular to the clamping member 240.

[0034] The limiting plate 260 is arranged perpendicularly to the clamping member 240, which further restricts the displacement of the battery, prevents shaking or displacement during processing, and ensures the accuracy of the electrode position and processing stability.

[0035] Specifically, refer to Figure 6 The displacement mechanism 300 includes a first motor 310 mounted on a frame 100. The output end of the first motor 310 is fixedly connected to a lead screw 320. The outer wall of the lead screw 320 is threadedly connected to a slide table 330. The surface of the frame 100 is fixedly connected to a guide rail 340. The slide table 330 is slidably connected to the guide rail 340. The second motor 410 is fixed on the slide table 330.

[0036] The displacement mechanism 300 drives the lead screw 320 via the first motor 310 to move the slide table 330 along the guide rail 340, thereby achieving precise feeding of the composite grinding head assembly 400, controlling the grinding depth and stroke, avoiding the uncertainty of manual operation, and improving the processing accuracy and automation level.

[0037] The specific working steps of this lead-acid battery tab deburring device are as follows: 1. Clamping and positioning The operator places the lead-acid battery on the positioning table 210 of the battery positioning fixture 200, so that the battery tabs are roughly facing the processing direction.

[0038] Rotating the adjustment knob 250 causes the threaded rod 230 to rotate. Since the threads at both ends of the threaded rod 230 are in opposite directions, the two clamping parts 240 slide towards each other within the clamping groove 220.

[0039] By continuously rotating the adjustment knob 250, the two clamping parts 240 and the limiting plate 260 on them are reliably clamped and centered on the battery from both sides, ensuring that the battery tabs are in the preset processing position.

[0040] 2. Startup and Positioning When the equipment is started, the first motor 310 of the displacement mechanism 300 starts working, driving the lead screw 320 to rotate.

[0041] The rotation of the lead screw 320 drives the slide table 330 to move precisely along the guide rail 340, thereby delivering the composite grinding head assembly 400 mounted on it to the station where the battery tab is located.

[0042] After being moved to the set position, the through groove 431 on the burr cleaning head 430 is exactly aligned with the coaxial line of the lead-acid battery's tab.

[0043] 3. Feeding and deburring process The second motor 410 of the composite grinding head assembly 400 is started, driving the burr removal head 430 to rotate at high speed via the rotating shaft 420.

[0044] The displacement mechanism 300 controls the slide 330 to continue fine feeding along the guide rail 340 toward the battery.

[0045] Side deburring: The tab gradually enters the through groove 431, and its side is subjected to high-speed grinding with the first abrasive layer 440 in the through groove 431, and the side burrs are completely removed.

[0046] Deburring at the root of the thread: At the same time, the side of the electrode contactes the second abrasive layer 470 inside the cleaning block 460. Under the adaptive pressure of the spring 450, the cleaning block 460 is in close contact with the side of the electrode, and the high-speed rotating bristles effectively grind and remove the burrs at the root of the thread on the side of the electrode.

[0047] 4. Exit and Reset After the deburring process is completed, the first motor 310 of the displacement mechanism 300 reverses, driving the lead screw 320 to move the slide table 330 and the composite grinding head assembly 400 backward along the guide rail 340, disengaging from the processed tab.

[0048] The second motor 410 stops rotating, and the grinding head stops rotating.

[0049] The slide 330 returns to its initial standby position, ready for the next machining cycle.

[0050] 5. Unloading The operator rotates the adjustment knob 250 in the opposite direction to release the battery from the clamp 240.

[0051] Remove the deburred lead-acid battery from the battery positioning fixture 200.
