Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery production technology, and in particular to a lead-acid battery grid cleaning device. Background Technology

[0002] During the casting process of lead-acid battery grids, the ends of the grids and the edges of the reinforcing ribs often have some burrs. These burrs can easily cause the back of the lead paste to be squeezed out during the coating process, resulting in insufficient paste after coating, exposed ribs on the grid, and poor coating effect on both sides of the grid. Larger grid burrs can also cause the coating process to jam. If grid burrs are carried into the grid, they may even puncture the separator and cause a short circuit inside the battery, seriously affecting the quality of lead-acid batteries.

[0003] Currently, a cutter is generally used to trim the edges of the grid at both ends to remove some burrs. However, during the trimming process, because the conveyor belt lacks a centering positioning structure, the grid may shift in position when it reaches the trimming station, resulting in poor trimming quality. Moreover, burrs on the edges of the grid ribs are difficult to remove.

[0004] The technical problem that this invention aims to solve is: how to improve the cleaning effect of burrs on the grid. Utility Model Content

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application implemented as described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Example 1

[0032] refer to Figure 1-5 A lead-acid battery grid cleaning device includes a first conveyor belt 1, a centering unit 2, a base 3, a cutting unit 4, and a cleaning unit 5;

[0033] The first conveyor belt 1 is used to transport the grid onto the base 3;

[0034] The centering unit 2 is connected to the first conveyor belt 1; the centering module is used to position the grid in the middle of the first conveyor belt 1.

[0035] The base 3 is arranged on one side of the first conveyor belt 1 along the conveying direction; the base 3 is inclined downward along the conveying direction so that the grid can slide down onto the cleaning unit 5 under the action of gravity; the base 3 is provided with a limiting module 6 that can slide along the thickness direction of the base 3; the limiting module 6 is used to support the grid ears so that the grid stays on the base 3.

[0036] The cutting unit 4 is located above the base 3, and the cutting unit 4 is used to remove burrs from the edges of both ends of the grid.

[0037] The cleaning unit 5 is arranged on the side of the trimming unit away from the first conveyor belt 1 along the conveying direction; the cleaning unit 5 is used to remove burrs from the grating ribs.

[0038] In this embodiment, the centering module is located on the side of the first conveyor belt 1 near the base 3 along the conveying direction; the height of the first conveyor belt 1 is higher than the highest point of the base 3; the height of the cleaning unit 5 is lower than the lowest point of the base 3.

[0039] The working process of the cleaning device is as follows: After the grid is cast, it is conveyed to the first conveyor belt 1. The first conveyor belt 1 drives the grid to move towards the base 3. When it reaches the side of the first conveyor belt 1 close to the base 3, the centering unit 2 pushes the grid so that the grid moves towards the middle of the first conveyor belt 1, so that the grid is kept in the center position when it enters the base 3. When the grid enters the base 3, the limiting module 6 extends out of the top side of the base 3, and the pole ears of the grid contact the limiting module 6, so that the grid is temporarily fixed on the base 3. The cutting unit 4 moves towards the base 3 and cuts off the burrs at both ends of the grid. After the cutting is completed, the limiting module 6 retracts into the base 3. Due to gravity, the grid slides down onto the cleaning unit 5. The cleaning unit 5 cleans the burrs on the grid ribs.

[0040] It should be noted that the cutting unit 4 and the base 3 are existing technologies. The cutting unit 4 includes a cylinder and a cutting plate. Both ends of the cutting plate along the conveying direction are provided with cutting blades. The base 3 is provided with through slots corresponding to the positions of the cutting blades. After the limiting module 6 supports the grid, the through slots are located at the two ends of the grid. The cylinder drives the cutting plate to move toward the base 3, and the cutting blades are inserted into the through slots to remove the burrs at both ends of the grid.

[0041] Preferably, the centering unit 2 includes a bracket 21, a baffle plate 22, and a first drive module 23; the first drive module 23 is connected to the bracket 21; the bracket 21 is connected to the first conveyor belt 1; there are two baffle plates 22, which are arranged at intervals within the bracket 21 along the width direction of the first conveyor belt 1; the baffle plates 22 are slidably connected to the bracket 21.

[0042] The first drive module 23 is provided with a gear 25; both baffles 22 are provided with racks 24, and both racks 24 mesh with the gear 25. The first drive module 23 is used to drive the gear 25 to rotate so that the two racks 24 respectively drive the two baffles 22 to move closer or further away from each other.

[0043] In this embodiment, baffle plates 22 are symmetrically arranged on the inner wall of the top of the support 21. The baffle plates 22 are slidably connected to the support 21 via a slide rail. A rack 24 is provided on the baffle plate 22. The length direction of the rack 24 extends along the length direction of the slide rail. The two racks 24 respectively mesh with the two ends of the gear 25 along the conveying direction.

[0044] The specific working process of the centering module is as follows: When the grid is conveyed to the bottom of the support 21, the first drive module 23 drives the gear 25 to rotate, which drives the rack 24 to move, thereby causing the baffles 22 to move closer to each other. The baffles 22 push the two sides of the grid so that the grid is located in the middle of the first conveyor belt 1. After the adjustment is completed, the first drive module 23 drives the gear 25 to rotate in the opposite direction, thereby causing the baffles 22 to move away from each other. The first conveyor belt 1 conveys the grid to the base 3.

[0045] The first drive module 23 is a motor.

[0046] Preferably, the limiting module 6 includes a limiting post 61 and a second driving module 62; the limiting post 61 is slidably connected to the base 3; the length direction of the limiting post 61 extends along the thickness direction of the base 3; the second driving module 62 is connected to the base 3; the power output end of the second driving module 62 is connected to the limiting post 61; the second driving module 62 is used to drive the limiting post 61 to extend from the top side of the base 3 to support the tabs of the plate grid.

[0047] In this embodiment, the second drive module 62 pushes the limiting post 61 out of the top side of the base 3. After the grid plate enters the base 3, it slides along the top side of the base 3 due to gravity until the tabs of the grid plate overlap the limiting post 61. After the cutting is completed, the second drive module 62 pulls the limiting post 61 back into the base 3. Since the grid plate is no longer supported, it continues to slide along the top side of the base 3 and enters the cleaning unit 5.

[0048] The second drive module 62 is a cylinder. The limiting post 61 is made of plastic.

[0049] Preferably, the cleaning unit 5 includes a second conveyor belt 51, a sweeping module 52, and a vacuuming module 53; the second conveyor belt 51 is arranged on the side of the base 3 away from the first conveyor belt 1; the vacuuming module 53 is connected to the second conveyor belt 51; and the sweeping module 52 is connected inside the vacuuming module 53.

[0050] In this embodiment, the specific working process of the cleaning unit 5 is as follows: the grid falls from the base 3 onto the second conveyor belt 51, the second conveyor belt 51 transports the grid to the area below the dust collection module 53, the cleaning module 52 cleans the grid and removes the burrs on the grid ribs, and the dust collection module 53 extracts the cleaned burrs to prevent them from falling into the outside world and affecting the health of the staff. Moreover, by setting up the dust collection module 53, the collected burrs can also be recycled.

[0051] Preferably, the dust collection module 53 includes a dust collection chamber 531, which is connected to the second conveyor belt 51; the cleaning module 52 is disposed inside the dust collection chamber 531; the dust collection chamber 531 is provided with an exhaust port 532; and the exhaust port 532 is connected to an external exhaust device.

[0052] In this embodiment, the cleaning module 52 is connected inside the dust collection chamber 531. After the cleaning module 52 cleans the burrs on the grid ribs, the exhaust device extracts the burrs swept off inside the dust collection chamber 531 through the exhaust port 532.

[0053] Preferably, the cleaning module 52 includes a first drive assembly 521, a lifting platform 522, a brush disc 523, a second drive assembly 524, and a pressing assembly 525; the lifting platform 522 is slidably connected to the dust collection chamber 531, and the lifting platform 522 is disposed inside the dust collection chamber 531; the first drive assembly 521 is connected to the dust collection chamber 531; the first drive assembly 521 is used to drive the lifting platform 522 to move up and down inside the dust collection chamber 531; the brush disc 523 is rotatably connected to the center position of the lifting platform 522; the second drive assembly 524 is connected to the lifting platform 522; the second drive assembly 524 is used to drive the brush disc 523 to rotate; the number of pressing assemblies 525 is multiple, and the multiple pressing assemblies 525 are arranged around the outer periphery of the brush disc 523, and the pressing assemblies 525 are slidably connected to the lifting platform 522; the pressing assemblies 525 are used to press the surface of the grid.

[0054] In this embodiment, the lifting platform 522 is provided with a guide shaft, and the lifting platform 522 is slidably connected to the dust collection chamber 531 through the guide shaft. The bottom of the brush disk 523 is provided with brush bristles.

[0055] The specific working process of the cleaning module 52 is as follows: When the grid enters below the dust collection chamber 531, the first drive component 521 drives the lifting platform 522 to move downward and causes the pressing component 525 to press the four ends of the grid. At the same time, the bristles at the bottom of the brush disk 523 contact the surface of the grid. Then the second drive component 524 is activated, and the second drive component 524 drives the brush disk 523, so that the bristles clean the burrs on the grid ribs. By fixing the grid first and then cleaning the grid, the burrs can be removed more effectively.

[0056] The first drive assembly 521 is a cylinder, and the second drive assembly 524 is a motor.

[0057] Preferably, the pressing assembly 525 includes a sliding rod 5251 and an elastic element 5252; both ends of the sliding rod 5251 are provided with limiting blocks; the sliding rod 5251 is slidably connected to the lifting platform 522; the length direction of the sliding rod 5251 extends vertically; the elastic element 5252 is sleeved on the sliding rod 5251; both ends of the elastic element 5252 contact the bottom side surface of the lifting platform 522 and the limiting block, respectively.

[0058] In this embodiment, the sliding rod 5251 is slidably connected to the lifting platform 522 along the outer peripheral surface of the brush disk 523. When the first drive assembly 521 drives the lifting platform 522 to move downward, the sliding rod 5251 will also descend with the lifting platform 522. After the end of the sliding rod 5251 contacts the surface of the plate grid, the first drive assembly 521 continues to drive the lifting platform 522 to descend until the bristles of the brush disk 523 contact the surface of the plate grid. During this process, the sliding rod 5251 slides on the lifting platform 522 in the opposite direction away from the plate grid, while the elastic element 5252 is compressed, thereby causing the limiting block on the sliding rod 5251 to gradually press the plate grid.

[0059] When the first drive assembly 521 moves the lifting platform 522 upward, the elastic element 5252 gradually returns to its initial state, thereby gradually reducing the clamping force of the sliding rod 5251 on the grid until the sliding rod 5251 disengages from the grid surface. In this way, the grid is prevented from being subjected to a large instantaneous impact force, which could cause it to shift.

[0060] The elastic element 5252 is a spring.

[0061] Preferably, a collection frame 7 is provided below the base 3; the collection frame 7 is used to collect burrs from both ends of the grid.

[0062] In this embodiment, a collection frame 7 is provided below the base 3. After the cutter cuts the burrs at both ends of the grid, the burrs enter the collection frame 7 through the through groove, thereby collecting the burrs for subsequent recycling or centralized processing.

[0063] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
