[0089] Solar energy is a renewable clean energy. Using solar energy to generate electricity has been increasingly valued and favored by people. Although solar cells can now be automatically welded by string welding machines, in the existing production process, the welding ribbon needs to be straightened, cut, transported and laid. In the existing technology, the processing efficiency of the welding ribbon is low, which affects the production efficiency of the product.

[0090] In view of this, the present invention provides a welding strip processing structure, wherein: Figures 1 to 11 A schematic structural diagram of an embodiment of a solder strip processing structure provided by the present invention.

[0091] Please also read Figures 1 to 7 The solder strip processing structure 100 includes a mounting body 1, a movable body 2 and a cam driving mechanism 3. A channel 11 extending leftward and rightward is formed in the mounting body 1 for the solder strip to pass through. The movable body 2 is formed with a connecting end and an action end distributed up and down. The action end is movably mounted in the channel 11 along the up and down directions, and the connecting end extends upward out of the channel 11. The cam driving mechanism 3 includes a driving cam 31 structure rotatably mounted to the mounting body 1. The driving cam 31 structure is formed with a driving part, and the driving part is drivingly connected to the connecting end to drive the movable body 2 to move so that the action end processes the solder strip.

[0092] In the technical solution of the present invention, a channel 11 for the welding strip to pass through is formed in the installation body 1, and the movable body 2 is formed with a connecting end and an action end distributed in the upper and lower directions. The action end is movably installed in the channel 11 along the upper and lower directions, and the connecting end extends upward out of the channel 11. The driving part of the driving cam 31 structure is drivingly connected to the connecting end to drive the movable body 2 to move so that the action end processes the welding strip. The driving part drives and controls the position of the connecting end to realize the driving of the movable body 2. During the entire operation process, the driving cam 31 structure keeps rotating, which reduces the waiting time for operation and improves the production efficiency of the product.

[0093] It should be noted that most of the prior art uses a linear drive structure, such as a cylinder or a pneumatic cylinder, to directly drive the movable body 2 to move. For example, a pneumatic cylinder drive requires an electrically controlled cylinder extension and retraction movement, which is more difficult to control, and the intermittent time difference between the processes cannot be precisely controlled.

[0094] In addition, during the production process, the welding strip needs to be straightened, cut, transported and laid, and during the whole process, the welding strip needs to be pressed or clamped, as well as cut. In one embodiment, the movable body 2 includes a pressing rod 2a extending upward and downward, the upper end of the pressing rod 2a is driven and connected to the driving part, and the lower end extends into the channel 11. The lower end of the pressing rod 2a corresponds to the action end, which is used to press and hold the welding strip. By pressing the welding strip with the pressing rod 2a, the welding strip can be straightened and transported.

[0095] The present invention does not limit the driving method of the driving cam 31 structure and the holding rod 2a. It can be a cam eccentric shaft, and the upper end of the holding rod 2a is sleeved on the cam eccentric shaft. It can also be a cam peripheral side surface pressing the holding rod 2a. In one embodiment, the driving cam 31 structure includes a driving cam 31, and the driving cam 31 is rotatably mounted to the mounting body 1. The driving part corresponds to the peripheral side surface of the driving cam 31. By designing the external contour curve of the driving cam 31, the movement of the holding rod 2a can be accurately controlled, which is convenient for designing the holding intermittent time difference.

[0096] The driving cam 31 can directly contact the holding rod 2a. In one embodiment, a rolling body 21 is provided at the connecting end and is rotatably installed along the front-to-back axis. The outer side surface of the rolling body 21 abuts against the outer side surface of the driving cam 31. Through the abutment between the driving cam 31 and the rolling body 21, a rolling friction method is adopted, which has small friction force and reduces the risk of wear of the driving cam 31.

[0097] In one embodiment, a rolling body 21 is provided at the connecting end and is rotatably installed along the front-rear axis. A first elastic member 22 is provided between the holding rod 2a and the mounting body 1 to reset the holding rod 2a upward. The downward power of the holding rod 2a is provided by the driving cam 31, and the upward power is provided by the first elastic member 22. The two cooperate to realize the upward and downward movement of the holding rod 2a, thereby improving production efficiency and having a better effect.

[0098] A holding rod 2a can be used in cooperation with the driving cam 31. Considering that some structures need to be avoided during the pushing process of the welding strip, such as the cutting knife 2b and other structures, in one embodiment, the mounting body 1 includes a mounting body and a connecting plate 12 arranged above the mounting body, and the connecting plate 12 is extended in the front-to-back direction. The movable body 2 also includes a transition rod 23 extending up and down, and the transition rod 23 is arranged at the left end of the connecting plate 12. The upper end of the transition rod 23 protrudes upward from the connecting plate 12 to form the connecting end. The upper end of the holding rod 2a is arranged at the right end of the connecting plate 12, and the middle position of the holding rod 2a is connected to the transition rod 23 to form a clearance space 24 between the right end of the connecting plate 12 and the upper end of the holding rod 2a, wherein the channel 11 is formed in the mounting body. Such a configuration facilitates the coordination between the welding strip processing structure 100 and other structures.

[0099] In one embodiment, a second elastic member 25 is provided between the connecting plate 12 and the mounting body to reset the transition rod 23 upward. The downward power of the transition rod 23 is provided by the driving cam 31, and the upward power is provided by the second elastic member 25. The two cooperate to realize the upward and downward movement of the transition rod 23, and then realize the upward and downward movement of the holding rod 2a, thereby improving production efficiency and having a better effect.

[0100] During the pushing process of the solder strip, in order to reduce the forward and backward upward position movement of the solder strip, in one embodiment, the solder strip processing structure 100 also includes a solder strip pushing guide component 4, and the solder strip pushing guide component 4 includes a pushing mounting seat 41 movably installed on the right end of the mounting body 1 along the forward and backward direction, and the pushing mounting seat 41 is provided with two pushing limit columns 42 spaced apart in the forward and backward directions, and a pushing limit space 43 is formed between the two pushing limit columns 42 for the solder strip to pass through so as to guide the solder strip. With such a configuration, before the solder strip processing structure 100 presses the solder strip, the positions of the solder strips are better maintained, thereby reducing the risk of the solder strip position movement.

[0101] In one embodiment, the left end face of the mounting body is penetrated with a push hole, the push soldering ribbon guide assembly 4 also includes a push position adjustment assembly, the push position adjustment assembly includes a push adjustment rod 44, a push placement seat 45 and a push adjustment screw 46, the push adjustment rod 44 is extended in the left and right directions, the right end of the push adjustment rod 44 is arranged on the push mounting seat 41, the left end is penetrated in the push hole, and protrudes from the left end face of the mounting body, the left end front side face of the push adjustment rod 44 is penetrated with a push adjustment screw The push adjustment hole has an inner thread on its inner wall, the push placement seat 45 is arranged on the left end surface of the mounting body, and is located on the rear side of the push adjustment rod 44, the front end surface of the push placement seat 45 is penetrated with a push placement hole, the screw section of the push adjustment screw 46 is passed through the push placement hole, and is threadedly installed in the push adjustment hole. With this arrangement, the push limit space 43 is a groove-shaped space, which is convenient for the insertion of the welding strip. On the other hand, the forward and backward position of the push limit space 43 can be adjusted.

[0102] The solder strip to be processed may be one strip or multiple strips along the front-back direction, such as 3 strips, 15 strips, 18 strips, etc., and correspondingly, multiple pressing rods 2a are required for pressing. In one embodiment, refer to Figure 3 and Figure 4 The driving cam 31 structure and the holding rod 2a are in one-to-one correspondence as a holding group. There are multiple holding groups and they are arranged at intervals along the front-to-back direction. Such an arrangement is suitable for processing wider structure battery strings or battery cell welding strips and has a better effect.

[0103] The plurality of driving cams 31 can be driven to rotate respectively by a driving device. In one embodiment, the driving cam 31 structure includes a driving cam 31, and the driving portion corresponds to the peripheral side surface of the driving cam 31. The cam driving mechanism 3 also includes a mounting shaft 32 rotatably installed along the front-rear axis. The plurality of driving cams 31 are all arranged on the mounting shaft 32. With such an arrangement, the plurality of driving cams 31 can be driven to rotate simultaneously by driving the mounting shaft 32 to rotate, thereby improving production efficiency.

[0104] The present invention does not limit the arrangement of the mounting shaft 32 and the driving cam 31. For example, they can be arranged separately, with the driving cam 31 being provided with an inner hole and then sleeved on the mounting shaft 32. Alternatively, the mounting shaft 32 can be directly processed into a camshaft. In one embodiment, a plurality of the driving cams 31 are arranged integrally with the mounting shaft 32. Such an arrangement facilitates improving the stability of the structure.

[0105] The method of driving the installation shaft 32 to rotate may be to provide power through a driving motor or the like, or to use a sprocket transmission method to realize power transmission. In one embodiment, the cam driving mechanism 3 also includes a first driving motor assembly 33, a mounting shaft 32 and a synchronous belt transmission mechanism 34.
