Detailed Description

In order that the above-recited objects, features and advantages of the present application will become more readily apparent, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments that are illustrated in the appended drawings.

The traditional welding strip carrying device generally adopts clamping jaws arranged left and right to clamp the welding strip, and the clamped welding strip is particularly a flat welding strip, so that the welding strip is easy to deviate and turn due to uneven stress, and can not be accurately covered on a grid line of a corresponding battery piece, and finally the welding quality of a battery string is influenced.

Therefore, the application provides a welding strip carrying device, wherein the clamping unit clamps two ends of the welding strip group in an up-down clamping mode, so that the clamped welding strip, in particular the flat welding strip, cannot turn over due to uneven stress.

The welding strip conveying device is configured to pick up a plurality of welding strip groups and lay the welding strip groups to a specified position.

As shown in fig. 1 to 2, the solder strip carrying device 10 in the embodiment of the present application includes a moving mechanism (not shown in the drawings), a mounting bracket 11, a plurality of pressing units 12, and a pressing unit driving mechanism 15, wherein:

the mounting bracket 11 is connected to a driving end of a moving mechanism, a pressing unit driving mechanism 15 is provided on the mounting bracket 11, and the moving mechanism is configured to drive the mounting bracket 11 to move.

A plurality of pressing units 12 are disposed side by side in order on the mounting bracket 11 in a first horizontal direction (X-axis direction as in fig. 1 and 2), and the pressing units 12 are configured to clamp the ends of the sets of welding strips up and down.

The hold-down unit drive mechanism 15 is configured to drive the hold-down unit 12 toward or away from the end of the solder strip set.

The clamping and conveying process of the butt welding belt group of the welding belt conveying device in the embodiment is as follows:

the moving mechanism first drives the plurality of pressing units 12 over the plurality of groups of solder strips to be picked up.

Then, the moving mechanism drives the plurality of pressing units to descend so that each pressing unit 12 is located on the side of the end of the corresponding welding set.

Next, the pressing unit driving mechanism 15 drives each pressing unit 12 to translate toward the corresponding welding strip group, so that the end portions of the welding strip group enter each corresponding pressing unit 12, and each pressing unit 12 then performs up-and-down clamping of the end portions of the welding strip group.

Finally, the moving mechanism drives the plurality of pressing units 12 holding the welding strip groups to the upper side of the designated position, each pressing unit 12 releases the end of the welding strip group, and the pressing unit driving mechanism 15 then drives each pressing unit 12 to translate away from the corresponding welding strip group, so that each welding strip group falls to the designated position after being separated from the pressing unit 12.

Therefore, the clamping of the end part of the corresponding welding strip group is implemented by the pressing unit 12 in an up-down clamping manner, so that the picked welding strip, particularly the flat welding strip, can be ensured not to turn over due to uneven stress.

In this embodiment, the solder strip handling device includes n+1 pressing units, and as shown in fig. 3, each of the remaining pressing units 12 includes a first pressing portion 13 and a second pressing portion 14, except for the 1 st pressing unit at the head and the n+1 st pressing unit at the tail. In each pressing unit 12, the first pressing portion 13 and the second pressing portion 14 are arranged in the same direction, for example, the first pressing portion 13 is arranged on the left side and the second pressing portion 14 is arranged on the right side.

The pressing unit driving mechanism 15 is configured to drive each of the first pressing portions 13 and each of the second pressing portions 14 to move toward the corresponding welding strip group along the first horizontal direction, so that two ends of each welding strip group penetrate into the corresponding first pressing portions 13 and second pressing portions 14 respectively, and move away from the corresponding welding strip group after the welding strip group is laid at a specified position by the welding strip conveying device.

By the above arrangement of the welding strip conveying device, each welding strip group is held by the first pressing portion 13 and the second pressing portion 14 of the adjacent two pressing units 12. Therefore, the welding strip conveying device can synchronously convey n welding strip groups which are staggered at one time. If n is set as the number of welding band groups required by one IBC battery string, one-time carrying can meet the welding band laying requirement of the one IBC battery string.

In addition, in the carrying process, the first pressing part 13 and the second pressing part 14 are controlled to move away from the corresponding welding band group, so that the welding band group is straightened, and finally, the welding band group can be accurately dropped to a designated position.

At this time, the welding strip is pulled to the bearing surface, wherein a welding strip exists under each pressing block 237.

When the movable clamping plate 233 slides to the low position, each pressing block 237 presses a corresponding welding strip on the pressure bearing surface.

The welding strip is pressed downwards to the pressure-bearing surface of the fixed clamping plate 232 by the pressing block 237, so that the welding strip is clamped, the stable clamping of various welding strips such as round welding strips, flat welding strips and the like can be ensured, and the welding strips are prevented from being overturned due to uneven stress.

Optionally, elastic pressure-bearing pieces 238 corresponding to the pressing pieces 237 one by one are arranged at intervals along the second horizontal direction on the upper end of the pressure-bearing surface of the fixing clamp 232.

When the movable clamping plate driving piece 234 drives the movable clamping plate 233 to slide towards the low position, the pressing block 237 firstly vertically descends to be in contact with the welding strip under the guidance of the first connecting column 235 and the first guide hole 236, then obliquely descends, and the welding strip is rubbed and pressed in the process until the welding strip is pressed on the pressure bearing surface, so that the pressing block 237 can be prevented from being rapidly pressed down in a moment to cause the welding strip, in particular the flat welding strip to be pressed and deformed.

When the movable knife block 263 slides to the high position, a gap for the welding strip to pass through is formed between the movable cutting edge of each hooking knife 267 and the fixed cutting edge of the fixed knife 262. When the movable knife block 263 slides to the low position, the movable cutting edge of each hooking knife 267 and the fixed cutting edge of the fixed knife 262 are matched to cut off the welding strip passing through the movable cutting edge and the fixed cutting edge.

The hook knife of the second strap cutting assembly 27 is staggered from the hook knife of the first strap cutting assembly 26 in the second horizontal direction by a distance equal to the spacing between the straps. Thus, the second ribbon splitting assembly 27 can complete the cutting of all even-numbered ribbons among the plurality of ribbons pulled to the ribbon handling device 20, and the avoidance of the odd-numbered ribbons can be achieved during the cutting process.

The hook knife is adopted as a cutting operation part, so that the first welding strip cutting assembly 26 and the second welding strip cutting assembly 27 can cut round welding strips, and also can cut flat welding strips, and the compatibility of the first welding strip cutting assembly 26 and the second welding strip cutting assembly 27 is increased.
