[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0023] Example 1:

[0024] As attached Figure 1 To be continued Figure 6 As shown:

[0025] This utility model provides a conveying device suitable for a string welding machine, comprising: a conveyor frame 1; a detection gantry 2 fixedly installed on the top left side of the conveyor frame 1; drive rollers 3 rotatably connected to the left and right ends of the conveyor frame 1; a conveyor belt 6 connected to the outer side of the drive rollers 3; a servo motor 4 fixedly installed at the bottom right end of the conveyor frame 1; adjusting blocks 7 slidably connected to the middle of the front and rear sides of the top of the conveyor frame 1; control cylinders 9 fixedly installed on the front and rear outer walls of the middle of the front and rear sides of the top of the conveyor frame 1; the detection gantry 2 on the top left side of the conveyor frame 1 is arched; three high-definition monitoring heads 201 are evenly installed on the bottom end face of the detection gantry 2; the high-definition monitoring heads 201 are connected to a computer controller. Next, in terms of specific function, when the battery pack passes under the detection gantry 2 along the conveyor belt 6, three high-definition monitoring heads 201 can take pictures of the battery pack's placement position from different angles and transmit the captured images to the computer controller. The computer controller analyzes these images to determine whether the battery pack is in the correct placement position. If there is a deviation in the battery pack's position, the computer controller will precisely control the control cylinders 9 at two different positions based on the analysis results. The control cylinders 9 drive the adjusting block 7 and the adjusting pad 8 to move, thereby adjusting the position of the battery pack on the conveyor belt 6, so that the battery pack can be in a more accurate position when entering the stringing process, improving the accuracy and efficiency of stringing.

[0026] The conveyor frame 1 has a central pad 101 in the middle. Two electromagnetic conveying rails 102 are symmetrically mounted horizontally on the top of the central pad 101. The conveyor belt 6 is arranged in a ring around the outside of the central pad 101. Circular, concave magnetic roller tracks 301 are symmetrically provided at the front and rear ends of the drive roller 3. The front end of the drive roller 3 is connected to the drive shaft at the front end of the servo motor 4 via a transmission belt 5. Two electromagnetic matching belts 601 are symmetrically provided on the front and rear sides of the inner wall of the conveyor belt 6. The electromagnetic matching belts 601 correspond to the electromagnetic conveying rails 102 on the conveyor frame 1, and are slidably connected to the magnetic roller tracks 301 of the drive roller 3. Conveying pads 602 are equidistantly provided on the outer wall of the conveyor belt 6, and the conveying pads 602 are symmetrically arranged on the front and rear sides of the outer wall of the conveyor belt 6. On the side, specifically, the transmission belt 5 connected to the drive shaft end of the servo motor 4 drives the drive roller 3 to rotate. With the cooperation of the electromagnetic matching belt 601 of the conveyor belt 6 and the magnetic roller track 301 of the drive roller 3, the conveyor belt 6 can stably follow the rotation of the drive roller 3. Through the corresponding setting of the electromagnetic matching belt 601 and the electromagnetic conveying slide rail 102, the slippage, deviation and collapse of the conveyor belt 6 during operation are reduced. At the same time, the weak magnetic force generated by the conveying pad 602 on the conveyor belt 6 is reduced, so as to reduce the shaking of the battery string when conveying it and improve the stability of the conveying. The conveying pad 602 on the outer wall of the conveyor belt 6 can increase the friction with the battery pack, prevent the battery pack from sliding during the conveying process, better fix the position of the battery pack, and ensure that the battery pack can be smoothly conveyed to the stringing position.

[0027] The conveyor frame 1 has two symmetrically arranged adjusting plates 103 on its top front and rear sides. Each adjusting plate 103 has a sliding perforation 10301. A control cylinder 9 is fixedly installed at the midpoint of the opposite sidewalls of the two adjusting plates 103. An adjusting block 7 is fixedly connected to the telescopic end of the control cylinder 9. Two sliding guide rods 701 are symmetrically arranged on the opposite sidewalls of the adjusting block 7 and the adjusting plate 103, slidingly connected to the sliding perforation 10301. A control cylinder 9 is fixedly installed at the midpoint of the right end of the opposite sidewalls of the two adjusting blocks 7. An adjusting pad 8 is fixedly connected to the telescopic end of the control cylinder 9. A guide rod is provided on the adjusting pad 8, slidingly connected to the adjusting block 7 and the adjusting plate 103 of the conveyor frame 1. The two control cylinders 9 at different positions are controlled by an external computer. Specifically, when the computer controller determines that the battery pack position needs adjustment based on the information fed back from the high-definition monitoring head 201, it controls the control cylinder 9 on the adjustment plate 103 to move. The telescopic end of the control cylinder 9 pushes the adjustment block 7 to slide along the sliding perforation 10301, thereby making an initial adjustment to the position of the battery pack in the front-back direction. At the same time, the control cylinder 9 on the adjustment block 7 pushes the adjustment pad 8 to further fine-tune the position of the battery pack, so that the battery pack can be accurately positioned in the position required for string welding. The sliding of the sliding guide rod 701 and the guide rod on the adjustment pad 8 in the sliding perforation 10301 ensures the stability and accuracy of the movement of the adjustment block 7 and the adjustment pad 8, ensuring the precision of the battery pack position adjustment, thereby improving the quality and efficiency of string welding.

[0028] The specific usage and function of this embodiment are as follows:

[0029] When using the conveyor equipment suitable for string welding machines, the battery packs to be stringed are first neatly placed on the conveyor pads 602 on the outer wall of the conveyor belt 6. Then, the servo motor 4 is started by the computer controller. The drive shaft of the servo motor 4 drives the drive roller 3 to rotate via the transmission belt 5. During the rotation of the drive roller 3, the electromagnetic matching belt 601 of the conveyor belt 6 and the magnetic roller track 301 of the drive roller 3 are closely matched. At the same time, the electromagnetic matching belt 601 and the electromagnetic conveying slide rail 102 are correspondingly set. This allows the conveyor belt 6 to stably follow the rotation of the drive roller 3, effectively reducing slippage, deviation, and collapse. Moreover, the interaction between the electromagnetic conveying slide rail 102 and the electromagnetic matching belt 601 will generate a weak magnetic force on the conveyor pads 602, further reducing the shaking of the battery packs during the conveying process and ensuring that the battery packs are smoothly conveyed to the string welding station. When the battery packs pass under the detection gantry 2 with the conveyor belt 6, Three high-definition monitoring cameras 201, equidistantly installed on the bottom end face of the inspection gantry 2, begin operation. They take pictures of the battery pack's placement from different angles and transmit the images to the computer controller in real time. If the computer controller determines, based on the image analysis results, that there is a deviation in the battery pack's position, it immediately issues a control command to the control cylinder 9 on the adjustment plate 103 according to a preset program and algorithm. The telescopic end of the control cylinder 9 begins to move, pushing the adjustment block 7 to slide along the sliding perforation 10301 in the adjustment plate 103. Since two sliding guide rods 701 are symmetrically provided on the side wall opposite to the adjustment plate 103 and are slidably connected in the sliding perforation 10301, this ensures the stability and accuracy of the movement of the adjustment block 7, thereby making an initial adjustment to the battery pack's position in the front-back direction. At the same time, the telescopic end of the control cylinder 9 on the adjustment block 7 pushes the adjustment pad 8 to further fine-tune the battery pack's position.

[0030] Example 2:

[0031] By adding an angle adjustment device to the adjusting plate 103, the adjusting block 7 can be rotated within a certain range. For some battery packs that require specific angles for string welding, the computer controller controls the angle adjustment device on the adjusting plate 103 to drive the adjusting block 7 and the adjusting pad 8 to rotate, so as to accurately correct the angle of the battery pack and ensure that the battery pack is in the best condition when entering the string welding process.
