A welding demolding tool

Abstract

The application relates to the technical field of tab welding, and discloses a welding demolding tool, which comprises a fixing plate, a sliding rail, a gas cylinder, a first sliding block, a demolding roller, a horizontal moving assembly and a rotary cleaning assembly. The demolding tool is provided with the rotary cleaning assembly. When oil stains are attached to the surface of the demolding roller, the curved scraper moves horizontally on the surface of the demolding roller, thereby scraping off the oil stains on the surface of the demolding roller, so that secondary pollution is avoided during demolding by the demolding roller. Because the curved scraper can rotate on the demolding roller, each part of the outer surface of the demolding roller can be scraped and cleaned. During the movement of the demolding roller and the contact with the product, the rotation of the curved scraper can avoid the generation of gaps between the contact part of the demolding roller and the product, thereby avoiding the damage of the product during demolding.

Description

Technical Field

[0001] This application relates to the field of electrode welding technology, specifically a welding demolding tool. Background Technology

[0002] Electrode welding refers to the process of connecting the electrode tabs (positive and negative lead-out pieces) of the battery cell to the external connecting pieces of the battery through welding during battery production. After welding, the electrode tabs and welding materials will still be in close contact. The demolding roller can quickly and smoothly separate them by displacement and pushing, avoiding delays caused by adhesion.

[0003] During the electrode welding process, the welding area will generate excessively high temperatures. These excessively high temperatures can easily cause the material surface to oxidize, forming an oily substance. This oily substance will fall onto the surface of the demolding roller due to gravity. When the demolding roller is subsequently pushed by displacement to achieve demolding, the oily contaminants will adhere to the surface of the product, causing additional pollution. Utility Model Content

[0004] The purpose of this application is to provide a welding demolding fixture to solve the problem mentioned in the background art that the oily contaminants generated at this time fall onto the surface of the demolding roller due to gravity, and when the demolding roller is subsequently pushed by displacement to achieve demolding, the oily contaminants will adhere to the surface of the product, causing additional pollution.

[0005] To achieve the above objectives, this application provides the following technical solution: a welding demolding fixture, comprising: a fixed plate, a slide rail, a cylinder, a first slider, a demolding roller, a horizontal moving assembly, and a rotary cleaning assembly. The main body of the demolding fixture consists of two sets of fixed plates spaced apart, a slide rail disposed on the outer walls of the two sets of fixed plates, a cylinder fixed to the two sets of fixed plates, and a first slider disposed on the output end of the cylinder. The first slider is slidably disposed on the slide rail and has demolding rollers fixed at both ends within the two sets of first sliders. The horizontal moving assembly is disposed on both sides of the first slider, and the rotary cleaning assembly is disposed on the horizontal moving assembly. The rotary cleaning assembly includes a movable component disposed on the horizontal moving assembly. The movable block has a circular hole at one end and a threaded hole at the other end. A track is integrally formed on the top of the movable block. The rotary cleaning assembly also includes a second slider slidably connected to the track of the movable block, a rack plate welded to the top of the second slider, a second motor fixed to the bottom of the movable block, a toggle block rotatably connected to the output end of the second motor via a shaft, the toggle block having a rectangular hole, a positioning rod welded to the outer wall of the second slider and located in the rectangular hole of the toggle block, and a curved scraper sleeved outside the demolding roller. A groove is formed in the center of the outer wall of the curved scraper, and a small rack is welded inside the groove of the curved scraper. The small rack meshes with the rack plate.

[0006] By adopting the above technical solution, the oil stains attached to the demolding roller can be scraped and cleaned automatically.

[0007] Preferably, the horizontal moving component includes a first fixing block welded to one side of the outer wall of the two sets of first sliders, and the first fixing block is L-shaped.

[0008] By adopting the above technical solution, a stable connection can be achieved for the guide rod welded on the inner wall.

[0009] Preferably, the horizontal moving component further includes a second fixing block welded to the other side of the outer wall of the two sets of first sliders. The second fixing block has a hole inside, and a bearing is provided inside the hole of the second fixing block.

[0010] By adopting the above technical solution, it is possible to provide stable rotation of the threaded rod inside the bearing.

[0011] Preferably, the horizontal moving assembly further includes guide rods with both ends welded to the inner walls of the two sets of No. 1 fixed blocks and threaded rods with both ends fixed in the bearings of No. 2 fixed blocks.

[0012] By adopting the above technical solution, the movable block on the guide rod can achieve stable displacement.

[0013] Preferably, the guide rod is disposed inside the circular hole of the movable block, and the threaded rod is threadedly connected inside the threaded hole of the movable block.

[0014] By adopting the above technical solution, the rotation of the threaded rod can drive the movable block to achieve stable displacement on the guide rod.

[0015] Preferably, the horizontal moving assembly further includes a first motor fixed on the outer wall of one of the set of second fixing blocks, and the output end of the first motor is connected to one end of the threaded rod.

[0016] By adopting the above technical solution, the screw rod on the output end can be rotated by the No. 1 motor.

[0017] In summary, this application includes at least one of the following beneficial effects:

[0018] (1) By setting a rotating cleaning component, when there is oil on the surface of the demolding roller, the curved scraper moves horizontally on the surface of the demolding roller to remove the oil, so that secondary pollution will not be caused during the demolding process. Because the curved scraper can rotate on the demolding roller, it can scrape and clean various parts of the outer surface of the demolding roller. During the process of the demolding roller moving and contacting the product, the rotation of the scraper can prevent gaps from forming between the demolding roller and the product, so that the product will not be damaged during the demolding process.

[0019] (2) By setting up a horizontal moving component and a rotary cleaning component, the rotary cleaning component can be driven to move back and forth on the demolding roller in an automated manner before the demolding roller moves to demold, thereby reducing manual intervention and improving cleaning efficiency.

[0024] 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. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] The following is in conjunction with the appendix Figure 1-3 The embodiments of this application will be described in further detail.

[0026] Example 1

[0027] Please see Figures 1-3 This embodiment provides a technical solution: a welding demolding fixture, including: a fixed plate 1, a slide rail 2, a cylinder 3, a first slider 4, a demolding roller 5, a horizontal moving assembly 6, and a rotating cleaning assembly 7;

[0028] The demolding fixture consists of two sets of fixed plates 1 spaced apart, slide rails 2 set on the outer walls of the two sets of fixed plates 1, cylinders 3 fixed on the two sets of fixed plates 1, a first slider 4 set on the output end of the cylinder 3, and demolding rollers 5 slidably set on the slide rails 2 and fixed at both ends in the two sets of first sliders 4. The above is the prior art and will not be described in detail below.

[0029] The horizontal moving assembly 6 is disposed on both sides of the first slider 4, and the rotating cleaning assembly 7 is disposed on the horizontal moving assembly 6. The rotating cleaning assembly 7 includes a movable block 701 disposed on the horizontal moving assembly 6. One end of the movable block 701 has a round hole, and the other end of the movable block 701 has a threaded hole. The top of the movable block 701 is integrally formed with a track. The rotating cleaning assembly 7 also includes a second slider 702 slidably connected to the track of the movable block 701, and a rack plate 703 welded to the top of the second slider 702. A second motor 704 located at the bottom of the movable block 701 is rotatably connected to a toggle block 705 at the output end of the second motor 704 via a shaft. The toggle block 705 has a rectangular hole. A positioning rod 706 is welded to the outer wall of the second slider 702 and located in the rectangular hole of the toggle block 705. A curved scraper 707 is sleeved on the outside of the demolding roller 5. A groove is provided in the middle of the outer wall of the curved scraper 707. A small toothed rack 708 is welded inside the groove of the curved scraper 707. The small toothed rack 708 meshes with the rack plate 703.

[0030] During the demolding process, the cylinder 3 on the fixed plate 1 is activated. During operation, the cylinder 3 drives the first slider 4 on the output end to achieve stable displacement on the slide rail 2 on the fixed plate 1. As the first slider 4 moves, it synchronously drives the demolding roller 5 to move, thereby pushing the product to demold. When the demolding roller 5 is not in use, the oil stains dripping onto the surface of the demolding roller 5 can be cleaned by the horizontal moving component 6 driving the rotating cleaning component 7.

[0031] During the movement of the movable block 701, the curved scraper 707 above it moves synchronously on the surface of the demolding roller 5, thereby removing oil stains. The second motor 704 is started, which drives the actuating block 705 connected by a shaft on the output end to rotate. During the reciprocating rotation of the actuating block 705, the internal positioning rod 706 and the second slider 702 connected to the positioning rod 706 can move reciprocally on the track of the movable block 701. During the movement of the second slider 702, the rack plate 703 at the top of the second slider 702 will move horizontally in sync. Because the rack plate 703 meshes with the small rack 708 of the curved scraper 707, the curved scraper 707 is driven to rotate around the demolding roller 5 during the horizontal movement, thereby scraping and cleaning all parts of the demolding roller 5.

[0032] Example 2

[0033] Please see Figures 1-3 This embodiment provides a technical solution: a welding demolding fixture, including: a first fixing block 601, a second fixing block 602, a guide rod 603, a threaded rod 604, and a first motor 605;

[0034] The horizontal moving component 6 includes a first fixing block 601 welded to one side of the outer wall of the two sets of first sliders 4. The first fixing block 601 is L-shaped and welded to the other side of the outer wall of the two sets of first sliders 4. The second fixing block 602 has a hole inside and a bearing is installed inside the hole of the second fixing block 602.

[0035] Guide rods 603 are welded to the inner walls of two sets of first-fixed blocks 601 at both ends, and threaded rods 604 are fixed in the bearings of second-fixed blocks 602 at both ends. The guide rods 603 are set inside the circular holes of the movable blocks 701, and the threaded rods 604 are threadedly connected to the threaded holes of the movable blocks 701. A first motor 605 is fixed on the outer wall of one set of second-fixed blocks 602, and the output end of the first motor 605 is connected to one end of the threaded rod 604.

[0036] When the first motor 605 is started, it can drive the threaded rod 604 in the bearing of the second fixed block 602 to rotate. During the rotation of the threaded rod 604, it can drive the movable block 701 connected to the threaded rod 604 to move stably on the guide rod 603 of the first fixed block 601.

[0037] The implementation principle of the welding demolding fixture of this application is as follows:

[0038] First, during the demolding process, the cylinder 3 on the fixed plate 1 is activated. During the operation of the cylinder 3, the first slider 4 on the output end can be driven to achieve stable displacement on the slide rail 2 on the fixed plate 1. During the movement of the first slider 4, the demolding roller 5 can be moved synchronously, thereby pushing the product to demold. When the demolding roller 5 is not in use, the oil stains dripping onto the surface of the demolding roller 5 can be moved by the horizontal moving component 6 to drive the rotating cleaning component 7, thereby cleaning the oil stains adhering to the surface of the demolding roller 5.

[0039] Secondly, start motor 605. When motor 605 is working, it can drive the threaded rod 604 in the bearing of fixed block 602 to rotate. During the rotation of threaded rod 604, it can drive the movable block 701 connected to the threaded rod 604 to move stably on the guide rod 603 of fixed block 601.

[0040] Finally, during the movement of the movable block 701, the curved scraper 707 above it moves synchronously on the surface of the demolding roller 5, thus removing oil stains. The second motor 704 is started, which drives the actuating block 705 connected to the output end via a shaft to rotate. During the reciprocating rotation of the actuating block 705, the internal positioning rod 706 and the second slider 702 connected to the positioning rod 706 move reciprocally on the track of the movable block 701. During the movement of the second slider 702, the rack plate 703 at the top of the second slider 702 moves horizontally in sync. Because the rack plate 703 meshes with the small rack 708 of the curved scraper 707, the curved scraper 707 rotates around the demolding roller 5 during the horizontal movement, thus cleaning all parts of the demolding roller 5.

[0041] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
