[0017] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.
[0018] See Figures 1-8 A preferred embodiment of the present invention provides a soft copper busbar production apparatus, comprising a feeding device 1, a processing device 2, a high-temperature diffusion welding device 3, and a post-processing device 4. The feeding device 1 is used to feed and combine multiple coiled copper sheets and transport them together, and to transport chrome-plated metal sheets to the upper and lower ends of the copper sheets. Specifically, multiple copper sheets are first transported in parallel and pressed together, and then two chrome-plated metal sheets are placed at the upper and lower ends of the multiple copper sheets.
[0019] The feeding device 1 includes multiple feeding rolls 101 symmetrically arranged along the center of the feeding frame. The multiple feeding rolls 101 can be arranged in two rows or four rows, with the horizontal center line of the feeding frame as the center. In specific arrangement, two feeding rolls 101 arranged vertically above and below the center of the feeding frame are grouped together, and a clamping mechanism 103 is provided after each group of feeding rolls.
[0020] All feed rolls 101 are wound with copper sheets. A guide wheel 102 for conveying copper sheets is provided on one side of the feed roll 101. After passing through the guide wheel 102, the copper sheets enter the pressing mechanism 103.
[0021] The clamping mechanism 103 includes a first mounting plate 1031 mounted on a feeding rack. The first mounting plate 1031 is provided with a fixed clamping wheel 1032 and an adjustable clamping wheel 1033. The adjustable clamping wheel 1033 is connected to an adjusting block 1034. The adjusting block 1034 is connected to a slide rail mechanism 1035 located on the feeding rack. The bottom of the adjusting block 1034 is connected to a slide rod 1036. The first mounting plate 1031 is also provided with a guide sleeve 1038. The slide rod 1036 is connected to the guide sleeve 1038, and a spring 1037 is provided between the slide rod 1036 and the lower part of the guide sleeve 1038. A pressure handle switch 1039 is provided in the upper region of the guide sleeve 1038 on the slide rod 1036.
[0022] By pressing the pressure handle switch 1039, the copper sheet can be pressed and tightened by the fixed pressure roller 1032 and the adjustable pressure roller 1033.
[0023] It also includes two chrome-plated metal sheet feeding devices 104 located at one end of multiple feeding rolls 101. Generally, there are two devices, one above the copper sheet being fed and one below, so that there is one chrome-plated metal sheet above and below the copper sheet.
[0024] The processing device 2 is used to cut the material conveyed by the feeding device 1 and weld the chrome-plated metal sheet and the copper sheet that is in close contact with it; the processing device 2 includes a first lead screw mechanism 21, a second lead screw mechanism 22 disposed at the driving end of the first lead screw mechanism 21, a feeding channel mechanism 23 disposed at one end of the second lead screw mechanism 22, a pressing and conveying mechanism 24 and a processing mechanism disposed at the driving end of the second lead screw mechanism 22. The processing mechanism is connected to the fixed plate at the drive end of the second lead screw mechanism 22; The processing mechanism includes a lower cutting cylinder 25 located at the bottom of the fixed plate, the lower cutting cylinder 25 being connected to a lower cutter 252 via a lower drive plate 251, and an upper cutting cylinder 26 located at the top of the fixed plate, the upper cutting cylinder 26 being connected to an upper cutter 262 via an upper drive plate 261. The processing mechanism includes a front clamping cylinder 29 disposed on the lower drive plate 251, the drive end of the front clamping cylinder 29 being connected to a front clamping block 291, and a rear clamping cylinder 210 disposed on the upper drive plate 261, the drive end of the rear clamping cylinder 210 being connected to a rear clamping block 2101. The processing mechanism includes an upper welding mechanism 27 located on the upper part of the fixed plate and a lower welding mechanism 28 located on the lower part.
[0025] The copper sheet conveyed by the feeding device 1 enters the pressing and conveying mechanism (24) after passing through the feeding channel mechanism (23). The pressing and conveying mechanism (24) is a double-headed cylinder that presses the copper sheet with upper and lower clamping plates. After pressing, the copper sheet is conveyed through the first screw mechanism or the second screw mechanism or the cooperation of the first screw mechanism and the second screw mechanism. The conveyed copper sheet enters the processing mechanism. The upper and lower cutters in the processing mechanism can cut the copper sheet. After cutting the copper sheet, since the copper sheet is still on a horizontal plane, it can still be pushed and conveyed. The front pressing block 291 and the rear pressing block 2101 are used to clean and press the front and rear sides of the copper sheet. The upper welding mechanism 27 and the lower welding mechanism 28 are used to weld the chromium-plated metal sheets on the upper and lower surfaces of the copper sheet.
[0026] After being conveyed by two lead screw mechanisms, the copper sheet enters the high-temperature diffusion welding device 3, which is used to perform diffusion welding on the copper sheet in the material conveyed by the processing device 2.
[0027] The post-processing device 4 is used to press the material after diffusion welding and put it into the material box 408.
[0028] The post-processing device 4 includes a housing 401, a lower sliding seat 402 slidably mounted on the housing 401, a guide mechanism 403 and a lower stamping die 4021 mounted on the lower sliding seat 402, and a stamping mechanism 404 mounted on the lower sliding seat 402. The driving end of the stamping mechanism 404 is connected to the upper stamping die 4041. It also includes a third lead screw mechanism 405 connected to the lower sliding seat 402, a clamping mechanism 406 mounted on the driving end of the third lead screw mechanism 405, and a chuck 407 mounted on the driving end of the clamping mechanism 406. The clamping mechanism 406 is a double-headed cylinder. A material box 408 is also provided below the third lead screw mechanism 405.
[0029] After welding, the copper sheet enters the post-processing device 4. Through the stamping mechanism 404, the upper stamping die 4041 and the lower stamping die 4021 can stamp the copper sheet into the required shape, usually a through hole. Then, it is clamped by the clamping mechanism 406 and moved by the third lead screw mechanism to be placed into the material box 408.
[0030] This device has the following advantages: This device can automatically perform the processes of pressing, welding, and stamping copper sheets; This device only requires three lead screw mechanisms set at the front and rear to achieve the conveying of soft copper busbars; When this device conveys copper sheets, it can make the copper sheets more tightly connected by pressing them multiple times. When processing copper sheets, this device can press them tightly from all sides.
[0031] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
