Description

Technical Field

[0001] The utility model relates to the technical field of welding devices, in particular to a copper strip connection welding device. Background Art

[0002] Copper tape is needed in the production of new energy electrodes. When feeding the copper tape, the copper tape roll needs to be assembled on the unwinding roller first, and then the free end of the copper tape is pulled out and put into the manufacturing equipment. As the copper tape is continuously consumed, the copper tape on the copper tape roll will be used up. At present, in the production process, when a roll of copper tape is used up, the staff generally needs to shut down the manufacturing equipment, then assemble another roll of copper tape in time, and then pull the free end of the new copper tape roll into the manufacturing equipment to complete the material change, and finally reopen the manufacturing equipment. In the above-mentioned traditional feeding method, the process of changing materials back and forth is relatively cumbersome. Each time the material is changed, the free end of the new copper tape roll needs to be pulled out into the manufacturing equipment, which results in low production efficiency and high labor intensity for workers. To this end, we propose a copper tape connection and welding device to solve the above problems well. Utility Model Content

[0003] The utility model aims to provide a copper strip splicing welding device, which is used to solve the problems raised in the above background technology.

[0004] The utility model is realized by the following technical solutions:

[0005] A copper strip connection welding device comprises a welding table and a welding mechanism installed on a vertical plate, wherein the welding mechanism is arranged directly above the welding table; a welding table cover plate is arranged on the top surface of the welding table, a gap is provided between the inner top surface of the welding table cover plate and the top surface of the welding table for the copper strip to pass through, and a welding opening is provided through the top surface of the welding table cover plate; a first pressing assembly and a second pressing assembly are respectively arranged on both sides of the welding opening on the welding table, and are used to respectively press the copper strip head and the copper strip tail to be welded when welding the copper strip;

[0006] A feeding roll is provided on the vertical plate at one side of the welding table. The feeding roll includes a first feeding roll and a second feeding roll, one of which is in a feeding state and the other is in a waiting state.

[0007] For example, when the copper tape of the first feeding roll is about to run out, when the tail of the copper tape of the first feeding roll enters the position of the second pressing assembly, the second pressing assembly presses the tail of the copper tape, and the tail end of the copper tape tail is at the welding port position. Then the copper tape head of the second feeding roll to be fed is manually pulled to the position of the first pressing assembly and pressed by it. The head end of the copper tape head is also at the welding port position and contacts the tail end of the copper tape tail. At this time, the welding mechanism is turned on to weld the copper tape tail on the first feeding roll and the copper tape head on the second feeding roll into a whole. After welding is completed, the first pressing assembly and the second pressing assembly release the copper tape, and the copper tape can continue to be fed into the manufacturing equipment. The device does not need to pass the copper tape through complex feeding rollers, and the welding equipment is located at the front end of the manufacturing equipment, which greatly reduces the intensity of manual operation and improves production efficiency. After the equipment is running, the used feeding roll can be replaced with a new one.

[0008] In order to further reduce the intensity of manual operation, the utility model is also provided with a pulling mechanism which automatically delivers the copper strip head to be fed to the welding table. The pulling mechanism is also arranged on the vertical plate and is located between the feeding roll and the welding table. The pulling mechanism is used to pull the copper strip head to be fed to the welding table.

[0009] Optionally, the pulling mechanism includes a first guide rail distributed laterally, a translation plate is provided on the first guide rail, the translation plate moves laterally on the first guide rail, the translation plate is also provided with a second guide rail distributed vertically, a mounting plate is provided on the second guide rail, the mounting plate slides vertically on the second guide rail, and a copper strip clamp for clamping the copper strip head is also provided on the mounting plate, the copper strip clamp is realized by the first guide rail and the second guide rail to realize the lateral and vertical movement and position change of the copper strip clamp, wherein the lateral movement realizes the pulling and feeding of the copper strip, and the vertical movement selectively selects to clamp the copper strip head on the feed roll in the state to be fed as the feeding state of the feed roll changes.

[0010] Optionally, a feed roller group is provided on the vertical plate in the forward direction of the welding table, and the feed roller group includes two feed rollers symmetrically distributed up and down, and both of the feed rollers are rotatably connected to the vertical plate. The feed roller is conducive to improving the stability of feeding the copper strip after welding.

[0011] In order to further reduce the intensity of manual operation, the pulling mechanism does not require manual participation when pulling the material, and a positioning mechanism is also arranged before the pulling mechanism. The positioning mechanism includes a clamping table and a third pressing assembly and a fourth pressing assembly located on the upper and lower sides of the clamping table. The third pressing assembly and the fourth pressing assembly selectively press the copper strip head of the feeding roll in the feeding state.

[0013] Furthermore, in order to enable the welding table to better receive the copper strip head transferred by the pulling mechanism, a negative pressure hole is provided on the welding table. When the pulling mechanism transfers the copper strip head to the vicinity of the welding table, the copper strip head is affected by the negative pressure on the welding table and quickly enters the welding table, and the tip of the copper strip head will not swing up and down.

[0014] Furthermore, the welding mechanism is an infrared welding machine or a laser welding machine, or other equipment that can heat the copper strip to achieve welding.

[0015] Furthermore, a sensor is provided on the copper strip feeding side of the positioning mechanism. The sensor is mounted on the vertical plate through a mounting frame. The sensor is used to detect whether the length of the copper strip head pressed by the positioning mechanism is long enough to prevent the pulling mechanism from failing to clamp the copper strip.

[0016] Furthermore, the sensor includes a first sensor and a second sensor, and the first sensor and the second sensor are respectively installed on the discharge sides of the third pressing assembly and the fourth pressing assembly.

[0037] like Figure 1-5 A copper strip connection welding device shown in the figure comprises a welding table 11 and a welding mechanism 12 installed on a vertical plate 1, wherein the welding mechanism 12 is arranged directly above the welding table 11; a welding table cover plate 13 is arranged on the top surface of the welding table 11, and a gap is provided between the inner top surface of the welding table cover plate 13 and the top surface of the welding table 11 for the copper strip 2 to pass through, and a welding opening 131 is provided through the top surface of the welding table cover plate 13; a first pressing component 3 and a second pressing component 4 are respectively arranged on both sides of the welding opening 131 on the welding table 11, which are used to respectively press the copper strip head and the copper strip tail to be welded when welding the copper strip 2;

[0038] Two feeding rolls 5 are provided on one side of the welding platform 11 on the vertical plate 1, one of which is in a feeding state and the other is in a waiting state. Figure 1 As shown, at this time, the first feeding roll 51 is in a feeding state, and the second feeding roll 52 is in a waiting state.

[0039] When the copper strip 2 of the first feeding roll 51 being fed is about to run out, when the copper strip tail of the first feeding roll 52 enters the position of the second pressing assembly 4, the second pressing assembly 4 presses the copper strip tail, and the tail end of the copper strip tail is at the welding port 131 position, and then the copper strip head of the second feeding roll 52 to be fed is pulled to the position of the first pressing assembly 3 and pressed by it, and the head end of the copper strip head is also at the welding port 131 position and contacts the tail end of the copper strip tail. At this time, the welding mechanism 12 is turned on to weld the copper strip tail on the first feeding roll 51 and the copper strip head on the second feeding roll 52 into a whole. After welding is completed, the first pressing assembly 3 and the second pressing assembly 4 release the copper strip 2, and the feeding of the copper strip 2 into the manufacturing equipment can be continued to realize feeding. The device does not need to pass the copper strip 2 through a complex feeding roller, and the welding equipment is located at the front end of the manufacturing equipment, the manual operation intensity is greatly reduced, and the production efficiency is improved. After the equipment is running, the used first feeding roll is replaced and replaced with a new feeding roll.

[0040] In this embodiment, a pulling mechanism 6 is also provided for automatically delivering the copper strip head to be fed to the welding table 11. The pulling mechanism 6 is also arranged on the vertical plate 1 and is located between the feeding roll 5 and the welding table 11. The pulling mechanism 6 is used to pull the copper strip head to be fed to the welding table 11.

The copper strip clamp 65 is moved laterally and vertically to change positions through the first guide rail 61 and the second guide rail 63, wherein the lateral movement realizes the pulling and feeding of the copper strip 2, and the vertical movement selectively selects to clamp the copper strip head on the feeding roll 5 in the feeding state as the feeding state of the feeding roll 5 changes, such as Figure 1 In the embodiment, the copper strip clamp 65 moves vertically downward to clamp the copper strip head on the second supply roll 52, and then moves horizontally to pull the copper strip head to the right to pull the copper strip head onto the welding table 11.

[0042] A feed roller set 14 is provided on the vertical plate 1 in the forward direction of the welding table 11. The feed roller set 14 includes two feed rollers 141 symmetrically distributed up and down, and both feed rollers 141 are rotatably connected to the vertical plate 1.
