Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding processing technology, specifically to a welding device for multiple rows of aluminum-copper conductive busbars. Background Technology
[0002] In the production process of conductive busbar welding, in order to ensure a tight weld between the end of the conductive busbar and the metal terminal, lead-in blocks and lead-out blocks are usually added to assist the welding process. For example... Figure 1 As shown in the figure: 101 is a conductive busbar, 102 is a metal terminal, 103 and 104 are both lead-in blocks, more specifically, 103 is an input block and 104 is an output block, a is the welding start point and b is the welding end point, and the direction of the line connecting a and b is the welding direction.
[0003] When welding the end of the busbar to the metal terminal, the busbar end and the metal terminal are usually placed on a corresponding fixture so that the part of the busbar end to be welded to the metal terminal is in contact. At the same time, an inlet block and an outlet block are respectively set on both sides of the contact part, so that the gap of the contact part is arranged along the line connecting the inlet block and the outlet block. Then, the position of the busbar end and the metal terminal is limited and fixed by a fixture, and then the gap of the contact part can be welded by a welding head.
[0004] The welding of the aforementioned conductive busbars and metal terminals is defined as a group. If multiple groups need to be welded at once, workers must sequentially arrange and fix multiple groups of conductive busbars and metal terminals on a fixture. Then, lead-in blocks and lead-out blocks are placed on both sides of each group to be welded before welding. After welding, the finished products are removed one by one. This operation is time-consuming and labor-intensive, as the finished products of the previous welding must be removed from the fixture before subsequent groups of conductive busbars and metal terminals can be sequentially arranged on the fixture for welding. In summary, the existing technology for conventional welding of multiple groups of conductive busbars and metal terminals is time-consuming, resulting in low production efficiency.
[0005] To address this issue, we propose a multi-row aluminum-copper conductive busbar welding device. Utility Model Content
[0006] The purpose of this invention is to solve the problems in the prior art by proposing a multi-row aluminum-copper conductive busbar welding device. The loading component in this welding device can be detached and installed on the tooling base, and the loading component is used to place multiple products to be welded. Multiple loading components can be set up and detached from the tooling base in turn to realize the assembly line welding operation of the products on the loading components, thereby improving the efficiency of welding processing.
[0007] To solve the above problems, this utility model provides the following technical solution:
[0008] A welding device for multi-row aluminum-copper conductive busbars includes a working base and a loading assembly detachably mounted on the working base. The loading assembly includes a loading plate and two clamping members. Multiple lead blocks are slidably arranged on the loading plate in the same direction, and an adjustable placement area is formed between any two adjacent lead blocks. The two clamping members are respectively disposed at both ends of the whole composed of multiple lead blocks, and the two clamping members can move close together or away. When the conductive busbar end and metal terminal are placed in the placement area, the two clamping members move close together, causing the placement area to become smaller and clamping and fixing the conductive busbar end and metal terminal.
[0009] As a further embodiment of the present invention: the carrier assembly further includes a first clamp for pressing the end of the conductive busbar onto the carrier plate and a second clamp for pressing the metal terminal onto the carrier plate, and the first clamp and the second clamp are respectively disposed on both sides of the integrally formed by multiple lead blocks.
[0010] As a further embodiment of this utility model: the first clamp includes a first pressure plate that is movably disposed on the carrier plate in the vertical direction, and an adjustable first pressing area is formed between the first pressure plate and the carrier plate.
[0011] As a further embodiment of this utility model: the second clamp includes a second pressure plate that is movably disposed on the carrier plate in the vertical direction, and an adjustable second pressing area is formed between the second pressure plate and the carrier plate.
[0012] As a further embodiment of this utility model: the welding device also includes an anti-retraction clamp for pressing the conductive busbar, the anti-retraction clamp including an anti-retraction pressing block movably disposed on the carrier plate in the vertical direction, and an anti-retraction pressing area of adjustable size is formed between the anti-retraction pressing block and the carrier plate.
[0013] As a further embodiment of this utility model: the first pressure plate, the second pressure plate, and the anti-retraction pressure block are all provided with fastening bolts that can be threadedly connected to the carrying plate.
[0014] As a further embodiment of this utility model: a limiting block and a pushing member are provided on the working base, and the actuating end of the pushing member can move closer to or further away from the limiting block, so that when the carrying plate is placed on the working base, it is clamped and fixed by the limiting block and the actuating end of the pushing member.
[0015] As a further embodiment of this utility model: a clamping member is provided on the working base, and the actuating end of the clamping member can move closer to or further away from the carrying plate.
[0016] As a further embodiment of this utility model, a U-shaped handle is provided on the carrier plate.
[0017] As a further embodiment of this utility model, the clamping component is a tightening screw.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] 1. By combining the working base and the carrying components into a one-to-many structure design, while one carrying component is used to carry the conductive busbar and metal terminals for welding, the operator can assemble the conductive busbar and metal terminals on other carrying components to prepare for subsequent welding, thus realizing assembly line operation. Compared with the one-to-one loading and unloading design in the prior art, the one-to-many design in this utility model shortens the assembly time and improves the welding efficiency.
[0020] 2. By setting the first clamp, the conductive busbar can be pressed tightly, so that the end of the conductive busbar can be stably placed on the placement area. Even if the carrier plate moves or is pressed during the welding process, the position of the conductive busbar can be kept stable.
[0021] 3. By setting the second clamp, the metal terminal can be well clamped, so that the metal terminal can be stably placed on the placement area, ensuring the relative stability of its position with the conductive busbar;
[0022] 4. By setting a rectangular clamping area on the working base, when a rectangular plate is placed on the working base, the plate will fall into the clamping area of the rectangular clamping area. Then, the four sets of pushers are driven to work, so that the actuators of the pushers can push the plate horizontally until the actuators of the four sets of pushers and multiple limit blocks clamp and lock the plate horizontally.
[0023] 5. By horizontally clamping and vertically clamping the work plate on the working base, the work plate can be kept stable on the working base. The above settings also ensure that the work plate is clamped in the same position on the working base each time, thus ensuring the accuracy of subsequent welding. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0036] like Figures 2-8 As shown, a welding device for multiple rows of aluminum-copper conductive busbars includes a single working base 1 and at least two load-bearing components 2. The load-bearing components 2 are detachably mounted on the working base 1. The load-bearing components 2 are used to support the conductive busbars 101 and metal terminals 102 to be welded. If the conductive busbars 101 and metal terminals 102 to be welded are considered as a group, the load-bearing components 2 can support multiple groups. That is, after the load-bearing components 2 are assembled on the working base 1, multiple groups of conductive busbars 101 and metal terminals 102 to be welded can be welded at one time, which improves the welding efficiency.
[0037] Specifically: During the automated welding process of one of the load-bearing components 2 on the working base 1, the operator can place multiple sets of conductive busbars 101 and metal terminals 102 to be welded on the load-bearing component 2. After the welding of the load-bearing component 2 on the working base 1 is completed, the load-bearing component 2 can be disassembled, and another load-bearing component 2 can be assembled on the working base 1 for further welding. This utility model differs from the cumbersome loading and unloading methods in the prior art. By setting a one-to-many loading and unloading design, it achieves rapid assembly of products to be welded on the working base 1, shortening production time and improving production efficiency.
[0038] like Figures 3-7 As shown, the above-mentioned loading component 2 includes a loading plate 201 with a handle 11 and two clamping members 202. Preferably, the handle 11 is U-shaped and the clamping members 202 are tightening screws. Multiple connector blocks 203 are slidably arranged on the carrier plate 201 along the same direction. In this embodiment, the multiple connector blocks 203 are slidably arranged on the carrier plate 201 along its width direction. An adjustable placement area 3 is formed between any two adjacent connector blocks 203. Two clamping members 202 are respectively arranged at both ends of the whole composed of multiple connector blocks 203, and the two clamping members 202 can move close to each other or separate from each other. When the end of the conductive bus 101 and the metal terminal 102 are placed in multiple placement areas 3, the two clamping members 202 move close to each other, causing multiple placement areas 3 to become smaller and clamping and fixing the end of the conductive bus 101 and the metal terminal 102. At this time, the carrier assembly 2 is in a ready state. If it is assembled on the working base 1, welding can be performed. Compared to conventional multi-point clamping methods in the prior art, the clamping and fixing method of this embodiment for multiple conductive busbars 101 and metal terminals 102 to be welded can achieve the clamping or loosening function of multiple conductive busbars 101 and metal terminals 102 to be welded by driving the two clamping members 202 to move. It is simple to operate and convenient to use.
[0039] like Figures 2-3 As shown, after multiple conductive busbars 101 and metal terminals 102 to be welded are clamped and fixed using two clamping members 202, in order to improve the clamping effect, the carrier assembly 2 further includes a first clamp for pressing the ends of the conductive busbars 101 onto the carrier plate 201 and a second clamp for pressing the metal terminals 102 onto the carrier plate 201. The first clamp and the second clamp are respectively located on both sides of the integrally formed by multiple connecting blocks 203. Figure 3 As shown, the first clamp is located on the right side and the second clamp is located on the left side. Specifically, the first and second clamps are configured as follows:
[0040] (1) First clamp: The first clamp includes a first pressure plate 4 that is movably disposed on the carrier plate 201 along the vertical direction, and an adjustable first pressing area is formed between the first pressure plate 4 and the carrier plate 201. During the process of placing the conductive busbar 101 on the carrier plate 201, the conductive busbar 101 will pass through the first pressing area, and then the first pressure plate 4 will be driven to press down and locked on the carrier plate 201 by fastening bolts 6, so that the conductive busbar 101 can be pressed tightly, so that the position of the conductive busbar 101 will not shift during subsequent movement or welding.
[0041] (2) Second clamp: The second clamp includes a second pressure plate 5 that is movably disposed on the carrier plate 201 along the vertical direction, and an adjustable second pressing area is formed between the second pressure plate 5 and the carrier plate 201. During the process of placing the metal terminal 102 on the placement area 3, the metal terminal 102 will pass through the second pressing area, and then the second pressure plate 5 will be driven to press down and locked on the carrier plate 201 by fastening bolts 6, so that the metal terminal 102 can be pressed and the position of the metal terminal 102 can be kept stable.
[0042] like Figure 3 As shown, based on the first clamping device for pressing the conductive busbar 101, since the conductive busbar 101 is elongated, the first clamping device only presses the end of the conductive busbar 101, while the other parts of the conductive busbar 101 remain free. Therefore, in some possible embodiments, an anti-retraction clamp for pressing the conductive busbar 101 is added. The anti-retraction clamp includes an anti-retraction block 7 that is movably mounted on the carrier plate 201 along the vertical direction, and the anti-retraction block 7 is connected to the carrier plate 201. An adjustable anti-retraction pressure zone is formed between 01 and 02. During the process of placing the conductive busbar 101 on the carrier plate 201, the conductive busbar 101 will pass through the anti-retraction pressure zone and the first pressure zone from right to left. Then, the first pressure plate 4 and the anti-retraction pressure block 7 are driven to press down and are locked on the carrier plate 201 by the fastening bolts 6. This can effectively press the conductive busbar 101 as a whole, further ensuring the stability of the conductive busbar 101 on the carrier plate 201.
[0043] like Figure 2 and Figure 8 As shown, for the disassembly and assembly design of the loading component 2 on the working base 1, a limiting block 8 and a pushing member 9 can be provided on the working base 1, and the actuating end of the pushing member 9 can move closer or further away from the limiting block 8 so that when the loading plate 201 is placed on the working base 1, it is clamped and fixed by the limiting block 8 and the actuating end of the pushing member 9. Figure 8The diagram shows a configuration with four sets of pushers 9 and multiple limit blocks 8. The four sets of pushers 9 are arranged in an L-shape, and the multiple limit blocks 8 are also arranged in an L-shape. The two L-shaped arrangements together form a horizontal rectangular clamping area. When a rectangular work plate 201 is placed on the working base 1, the work plate 201 will fall into the clamping area of the rectangular clamping area. Then, the four sets of pushers 9 are driven to work, so that the actuator of the pusher 9 pushes the work plate 201 horizontally until the actuator of the four sets of pushers 9 and the multiple limit blocks 8 clamp and lock the work plate 201 horizontally.
[0044] like Figure 8 As shown, in order to ensure the vertical stability of the carrying plate 201 on the working base 1, in some possible embodiments, a clamping member 10 is also provided on the working base 1. The actuating end of the clamping member 10 can move closer or further away from the carrying plate 201. After the carrying plate 201 is clamped and fixed horizontally, the actuating end of the clamping member 10 can be used to clamp the carrying plate 201 vertically to ensure the vertical stability of the carrying plate 201 on the working base 1.
[0045] In summary, by horizontally clamping and vertically tightening the carrier plate 201 on the working base 1, the carrier plate 201 can be kept stable on the working base 1. Furthermore, this arrangement ensures that the carrier plate 201 is always clamped at the same position on the working base 1, guaranteeing the accuracy of subsequent welding. It should be noted that the pushing component 9 and clamping component 10 mentioned above can be a cylinder, hydraulic cylinder, telescopic rod, or a series of other components capable of reciprocating motion.
[0046] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
