Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1 to Figure 4 The embodiment of the utility model provides a mobile fixed tray for a placement machine, comprising: an operating table 1, a front rail module 2 is installed above the operating table 1, and a rotating wheel 5 is installed on the inner side of the front rail module 2, a transmission belt 4 for transmission is arranged on the surface of the rotating wheel 5, and a driving rotating wheel 6 is installed below the rotating wheel 5, and a driving motor 7 is connected to the center line of the driving rotating wheel 6, a middle rail module 8 is installed at one end of the front rail module 2, and a rear rail module 12 is installed at the end of the middle rail module 8 away from the front rail module 2, the rotating wheel 5 is connected to the driving rotating wheel 6 through the transmission belt 4, and the driving motor 7 is connected to the driving motor 7 through a coupling;

[0027] Specifically, the PCB board can be placed from the position of the front track module 2, and the transmission belt 4 is used to transport the PCB board. The transport direction moves from the front track module 2 to the middle track module 8. After the chip is attached in the middle track module 8, it moves toward the rear track module 12 and unloads from the position of the rear track module 12 to avoid loading and unloading at the same position, which is easy to cause conflicts and lead to poor efficiency.

[0028] A moving seat 9 is slidably mounted on the inner wall of the middle rail module 8, a roller 10 is mounted on the bottom of the moving seat 9, and a load-bearing seat 11 for bearing weight is mounted below the middle rail module 8;

[0029] Specifically, the PCB board is placed on the moving seat 9, and the moving seat 9 is driven to move by the transmission belt 4. The rollers 10 of the moving seat 9 will roll to reduce resistance and help the PCB board to be transported and moved.

[0030] The structures of the middle rail module 8, the front rail module 2 and the rear rail module 12 are the same. A carriage 13 is installed on the outer side of the middle rail module 8, and a loading tray 14 is fixedly arranged on the surface of the carriage 13. A slide rail 15 is installed below the loading tray 14. The moving direction of the slide rail 15 is perpendicular to the conveying direction of the middle rail module 8. A push card seat 151 is slidably installed on the surface of the slide rail 15, and the push card seat 151 and the carriage 13 are connected to each other. The carriage 13 forms a sliding structure with the slide rail 15 through the push card seat 151, and the carriage 13 and the loading tray 14 are fixedly connected. The middle rail module 8, the front rail module 2 and the rear rail module 12 are all located on the same straight line, and the middle rail module 8 and the carriage 13 are perpendicular to each other.

[0031] Specifically, the middle rail module 8 is close to the loading tray 14, and the loading tray 14 moves toward the middle rail module 8 along the slide rail 15. This helps to shorten the distance from the chip on the loading tray 14 to the PCB board, speed up the loading speed, and improve production efficiency.

[0032] A width adjustment module for width adjustment is installed below the front rail module 2, and the width adjustment module includes: a mounting seat 304 installed at the bottom of the front rail module 2, a width adjustment screw rod 3 is inserted and installed on the surface of the mounting seat 304, an angular ball bearing 305 is installed on the surface of the width adjustment screw rod 3, a pulley 301 is fixedly installed on the end of the width adjustment screw rod 3, a driving wheel 302 connected to a driving source is installed below the pulley 301, and a tensioning shaft wheel 303 is installed on one side of the driving wheel 302 in the counterclockwise direction, the mounting seat 304 and the front rail module 2 are fixedly connected, and a rotating structure is formed between the angular ball bearing 305 and the width adjustment screw rod 3;

[0033] Specifically, by setting the width adjustment module, the width of the front rail module 2 is adjusted to adapt to PCB boards of different sizes. After the driving wheel 302 is driven by the driving source, the belt cooperates with the pulley 301 and the tensioning shaft wheel 303 to rotate the pulley 301. The pulley 301 is connected to the width adjustment screw rod 3, and the width adjustment screw rod 3 cooperates with the angular ball bearing 305 to push the front rail module 2 on one side to move, so that the width of the front rail module 2 can be adjusted.

[0034] The working principle of the utility model is:

[0035] When using the utility model, the moving seat 9 is moved to the transmission belt 4 on the position of the front rail module 2, and the driving motor 7 drives the driving wheel 6 to rotate. The driving wheel 6 cooperates with the wheel 5 through the transmission belt 4, thereby driving the transmission belt 4 to rotate forward, and then the PCB board placed on the moving seat 9 is moved, so that the PCB board is moved from the front rail module 2 to the middle rail module 8. When the PCB board is located in the middle rail module 8, the sliding structure between the slide rail 15 and the carriage 13 is used to fix the loading tray 14 and the carriage 13. The carriage 13 moves along the X-axis direction relative to the slide rail 15, so that the loading tray 14 keeps the PCB board close to the middle rail module 8 for loading. One end of the module 2 is transported to the middle rail module 8, where the chip in the loading tray 14 is grabbed by a robot and attached to the PCB board. After processing, the PCB board is moved to the rear rail module 12 through belt transmission for unloading. In addition, when loading on the front rail module 2, the driving source drives the driving wheel 302 to rotate, and the belt cooperates with the pulley 301 and the tensioning shaft wheel 303 to rotate the pulley 301. The pulley 301 is connected to the width adjustment screw rod 3, and the width adjustment screw rod 3 cooperates with the angular ball bearing 305 to push the front rail module 2 on one side to move, so that the width of the front rail module 2 can be adjusted, and then the width can be adjusted according to PCB boards of different sizes.
