[0025] Reference Figure 1 、 Figure 2 and Figure 3The present invention provides a non-destructive circuit board transfer vehicle, comprising a vehicle frame 100, a conveying mechanism, and a lifting mechanism 300. The vehicle frame 100 is a rectangular frame, and universal wheels 110 are provided at the four corners of the bottom of the vehicle frame 100. The conveying mechanism is connected to the vehicle frame 100 and comprises a frame 210, a driving assembly 220, a driving shaft 230, a plurality of driven shafts 240, and a plurality of rollers 241. The driving assembly 220 is provided on the frame 210 and is used to drive the driving shaft 230 to rotate. The driving shaft 230 can drive the driven shaft 240 to rotate. The plurality of rollers 241 are spaced apart on the driven shaft 240, and the rollers 241 are concentrically arranged with the driven shaft 240. The plurality of driven shafts 240 are all rotatably provided on the frame 210, and the driven shafts 240 are arranged parallel to each other and spaced apart, with a clearance 243 formed between two adjacent driven shafts 240. The lifting mechanism 300 is connected to the frame 100 and to the bottom of the conveyor mechanism, driving the conveyor mechanism up and down. It is understood that the design of the non-destructive circuit board transfer vehicle fully considers the characteristics of circuit boards and the safety of the transfer process. By using the conveyor mechanism, circuit boards can be smoothly transported from one location to another, avoiding scratches and damage caused by improper manual operation. This greatly improves the efficiency and accuracy of transfer and reduces the damage rate of circuit boards during transfer. The lifting mechanism 300 on the transfer vehicle can adjust the height of the conveyor mechanism according to actual needs, allowing it to adapt to transfer platforms or work surfaces of different heights. This design not only enhances the flexibility of the transfer vehicle but also improves its adaptability to various working environments. The drive assembly 220 drives the driving shaft 230 to rotate, which in turn drives the driven shaft 240 and rollers 241 to rotate. The rollers 241 are spaced apart to significantly reduce the contact area between the conveyor mechanism and the circuit boards. Compared to conveyor belts or rollers, scratches on the circuit boards caused by contact are further reduced, further ensuring the safety of circuit boards during transfer. It replaces manual board handling, avoids manual contact with the circuit boards and realizes the transportation of the circuit boards, thus avoiding the risk of human scratches on the board surface and is beneficial to production use.

[0026] Reference Figure 1 It should be noted that the length of the rack 210 extends beyond one side of the vehicle frame 100, allowing it to reach into the equipment and receive circuit boards. By designing the rack 210 longer than one side of the vehicle frame 100, the non-destructive circuit board transfer vehicle can more easily reach into the equipment and receive circuit boards. This design allows the transfer vehicle to dock directly with the output of production or processing equipment, streamlining the transfer process and reducing potential delays and errors.

[0027] Reference Figure 2It will be understood that the drive assembly 220 includes a first drive member 221, a driving pulley 222, a driven pulley 223, and a transmission belt 224. The first drive member 221 is fixed to the frame 210, and the driving pulley 222 is connected to the output end of the first drive member 221. The driven pulley 223 is connected to the driving shaft 230. The driving pulley 222 and the driven pulley 223 are arranged parallel to the axis of the driving shaft 230 and are connected by a transmission belt 224 sleeved on the outside. This design allows the first drive member 221 to rotate when it is activated, which in turn drives the driven pulley 223 and the driving shaft 230 to rotate via the transmission belt 224. The combination of the first drive member 221, the driving pulley 222, the driven pulley 223, and the transmission belt 224 achieves stable drive of the driving shaft 230. This drive method has a simple structure and high transmission efficiency, ensuring smooth operation of the transmission mechanism.

[0028] Reference Figure 1 and Figure 2 Furthermore, the driven shaft 240 is arranged orthogonally to the driving shaft 230, that is, the two are perpendicular to each other. A plurality of driving magnetic wheels 231 are fixedly connected to the outer wall of the driving shaft 230, and these driving magnetic wheels 231 are arranged concentrically with the driving shaft 230. A driven magnetic wheel 242 is fixedly connected to one end of the driven shaft 240 close to the driving magnetic wheel 231, and the driven magnetic wheel 242 is arranged concentrically with the driven shaft 240. This magnetic drive method enables the driven shaft 240 to rotate as the driving shaft 230 rotates, thereby driving the roller 241 to rotate. The magnetic force between the driving magnetic wheel 231 and the driven magnetic wheel 242 enables the driven shaft 240 to rotate as the driving shaft 230 rotates, without the need for an additional transmission mechanism, thereby reducing energy loss and improving transmission efficiency.

[0029] Reference Figure 1 and Figure 2 Furthermore, the conveying mechanism also includes a plurality of spacers 250, which are sequentially mounted on the driven shaft 240. The rollers 241 are mounted on the spacers 250, with each roller 241 abutting between two adjacent spacers 250. This design allows the rollers 241 to rotate stably on the driven shaft 240, and the spacing between the rollers 241 can be adjusted by adjusting the number and position of the spacers 250 to accommodate circuit boards of different sizes. The contact area between the rollers 241 and the circuit boards can be increased or decreased as needed, ensuring that the circuit boards can be received and transported while minimizing damage to the circuit boards during the transport process.

[0030] Reference Figure 2A mounting base 211 is provided on the side of the frame 210 near the driving shaft 230, and a bearing 212 is connected to the mounting base 211. The driving shaft 230 is rotatably connected to the mounting base 211 via the bearing 212. This design ensures stable rotation of the driving shaft 230 and reduces friction and wear during rotation. This ensures stable rotation of the driving shaft 230 while reducing friction and wear, thereby extending the service life of the transfer vehicle.

[0031] Reference Figure 1 and Figure 3 The lifting mechanism 300 includes a support rod 310 and a lifting rod 320. The support rod 310 is fixedly connected to the bottom of the frame 100, and the lifting rod 320 is connected to the conveying mechanism via a connecting plate 330. A second driving member 311 is provided on the support rod 310, which can drive the lifting rod 320 to move upward or downward, thereby adjusting the height of the conveying mechanism. Through the design of the lifting mechanism 300, the circuit board non-destructive transfer vehicle can easily adjust the height of the conveying mechanism, so that it can adapt to transfer platforms or work surfaces of different heights. This design enhances the adaptability and flexibility of the transfer vehicle and improves work efficiency.

[0032] Reference Figure 3 Furthermore, to ensure smooth movement of the lifting rod 320, this embodiment also incorporates a guide cylinder 321 mounted on the lifting rod 320. The guide cylinder 321 is integrally formed with the support rod 310, and the lifting rod 320 moves axially along the guide cylinder 321. This design not only enhances the stability of the lifting mechanism 300 but also ensures smooth lifting.

[0033] Reference Figure 3 The connecting plate 330 is rectangular, and four lifting rods 320 are provided, respectively located at the four corners of the connecting plate 330. This design enables the conveying mechanism to maintain balance during the lifting process, avoiding deviation or tilting caused by uneven force.

[0034] Reference Figure 1 It is understood that, for ease of operation, a handle portion 120 is further provided on one side of the top surface of the frame 100. The handle portion 120 is located on the side of the extension away from the frame 210, so that the operator can more conveniently hold the handle portion 120 when pushing the transfer vehicle, thereby improving the convenience and comfort of operation.
