The output shaft of the driving motor 23 is fixedly connected to the rotating shaft 22 on the left side. The driving motor 23 can rotate clockwise and counterclockwise. Under the connection of the rotating shaft 22, the driving motor 23 will drive the two synchronous belt groups 21 to run left or right at the same time to transport materials. A slide plate 3 is connected between the synchronous belt groups 21. The slide plate 3 is used to lift the material for transportation. It will move left or right under the drive of the two synchronous belt groups 21 to realize the left or right transportation of the material. The slide plate 3 is made of metal material with a relatively smooth surface. The shape of the slide plate 3 is a step-like shape with a raised middle part at the front and rear low parts, and a vacant part is provided in the raised part;

[0021] A fixed frame 31 is fixedly welded under the slide 3, a shaft sleeve 32 is rotatably provided inside the fixed frame 31, a through square groove is opened inside the shaft sleeve 32, a square shaft 41 is slidably provided in the square groove inside the shaft sleeve 32, the purpose of setting the square shaft 41 in the shaft sleeve 32 is that when the square shaft 41 moves up and down, the shaft sleeve 32 drives the square shaft 41 to rotate, a top plate 4 is fixedly connected to the top of the square shaft 41, a convex block is provided on the top plate 4, the height of the upper surface of the convex block is consistent with the height of the protrusion of the slide 3, the top plate 4 is located in the vacancy of the slide 3, and the inner side of the fixed frame 31 is close to the shaft A transmission group 33 is provided on one side of the sleeve 32. The transmission group 33 consists of a transmission motor and two gears. The two gears are respectively installed on the output shaft of the transmission motor and the outer side of the sleeve 32. The two gears are meshed with each other. When the transmission group 33 is running, it will drive the sleeve 32 to rotate synchronously. In the working state, the transmission motor of the transmission group 33 rotates 180 degrees each time. A cylinder 5 is fixedly provided at the bottom of the fixed frame 31. A rotating joint 51 is installed on the movable rod of the cylinder 5. The top of the rotating joint 51 is fixedly connected to the square shaft 41. When the cylinder 5 extends the movable rod upward, The square shaft and the top plate 4 are lifted upward by the rotating joint 51. When the transmission group 33 drives the shaft sleeve 32 to rotate, the square shaft 41 drives the rotating joint 51 to rotate. The purpose of setting the rotating joint 51 is that the rotating force of the square shaft 41 will not be transmitted to the movable rod of the cylinder 5. A plug-in rack 6 is slidably placed on the slide plate 3. The front and rear sides of the plug-in rack 6 are provided with grooved plates for vertically inserting and neatly placing the PCB board. The front and rear sides of the bottom of the plug-in rack 6 are fixedly connected with metal plates 62. The bottom side of the metal plate 62 is relatively smooth. The metal plate 62 is connected to the front and rear sides of the slide plate 3. The two sides are in sliding contact, and the metal plate 62 slides on the skateboard 3 more smoothly. A positioning groove 61 is provided at the lower part of the rack 6. When the top plate 4 is lifted up, it will be pushed out from the gap in the skateboard 3 to lift the rack 6 on the skateboard 3, and the protrusions arranged on the top plate 4 will fit with the positioning groove 61 at the bottom of the rack 6. When the top plate 4 is lifted up, the protrusions will first be stuck in the positioning groove 61 of the rack 6, and then the rack 6 will be lifted up. The purpose of this arrangement is that when the top plate 4 lifts the rack 6 for rotation, the rack 6 can be stabilized to a certain extent during rotation to reduce the possibility of falling due to force.

[0022] Embodiment 2: Based on embodiment 1, Figure 1 Slide In Figure 4As shown, it also includes a fixed frame 7, a lifting group 8 and a support plate 9. The right side of the mounting frame 2 is connected to the fixed frame 7, and the fixed frame 7 is equipped with a lifting group 8. The lifting group 8 consists of a lifting motor and a screw rod. The output shaft of the lifting motor is fixedly connected to one end of the lower part of the screw rod on the same side. When the lifting motor rotates, it will drive the screw rod on the same side to rotate, and the two lifting groups 8 operate synchronously. A support plate 9 is slidably provided between the fixed frames 7. The front and rear sides of the support plate 9 are respectively threadedly connected to the screw rods of the lifting groups 8 on the front and rear sides. When the lifting group 8 is running, the support plate 9 will move up and down with the action of the lifting group 8. The support plate 9 can be conveniently placed at a lower place for loading, and people do not need to lift the plug-in frame 6 with a certain weight and place it on the higher slide plate 3, which is convenient for labor-saving work.

[0023] The rack 6 with the PCB board is placed centrally on the slide plate 3, and then the drive motor 23 is started. The drive motor 23 rotates counterclockwise, driving the synchronous belt group 21 to rotate counterclockwise. Driven by the two synchronous belt groups 21, the slide plate 3 carries the rack 6 to the left for transmission. When the slide plate 3 moves to the material picking position on the left side of the synchronous belt group 21, the drive motor 23 is controlled to stop working, and the slide plate 3 stops moving. Then, the external material picking manipulator will take the PCB board in the rack 6 and process the A side of the PCB board. After the processing is completed, the PCB board will be put back into the rack 6. When the A side processing of the PCB boards in the rack 6 is completed, the cylinder 5 will push up and push up the rack 6 on the top plate 4, so that the rack 6 is out of contact with the slide plate 3, and the square shaft 41 moves upward in the sleeve 32. Subsequently, the transmission motor of the transmission group 33 rotates 180 degrees. Driven by the two meshing gears, the sleeve 32 rotates synchronously by 180 degrees. 0 degree, the square shaft 41 in the shaft sleeve 32 rotates 180 degrees accordingly, the top plate 4 rotates 180 degrees, and the rack 6 rotates synchronously under the drive of the top plate 4. After the rotation is completed, the cylinder 5 retracts the movable rod downward, driving the support plate 9 to reset, and the bottom of the rack 6 contacts the slide plate 3. At this time, the PCB board in the rack 6 has been turned over, and the external material-taking manipulator continues to take the PCB board in the rack 6 for B-side processing. Through the combined mechanism of the rack 6 and the top plate 4, the rack 6 can be rotated in a narrow position to improve work efficiency. The mechanism is simple and convenient to operate. When both sides of the PCB board in the rack 6 are completely processed, the driving motor 23 rotates clockwise, driving the synchronous belt group 21 to transfer materials to the right, driving the slide plate 3 to move to the right, and the rack 6 moves to the right under the drive of the slide plate 3. When the rack 6 moves to the right position of the device, the driving motor 23 is controlled to stop working, the rack 6 is taken away, and the processing is completed.

[0024] like Figure 3-4As shown, it also includes an electromagnet 10. The electromagnets 10 are provided at the concave parts on the front and rear sides of the top plate 4. The electromagnet 10 is in contact with the metal plate 62 on the same side. When the electromagnet 10 is energized, a magnetic field with a certain magnetic force will be formed in the electromagnet 10 body, which will produce a certain suction force on the metal that can be magnetically attracted. After the electromagnet 10 is energized, the metal plate 62 will be attracted and the rack 6 will be firmly fixed on the slide 3 to prevent the rack 6 from shifting left and right due to force during transportation.

[0025] like Figure 1 As shown, it also includes guide wheels 11. No less than five guide wheels 11 are evenly spaced and rotatably installed on the upper part of the fixed frame 7. The guide wheels 11 will roll in contact with the front and rear sides of the lower part of the plug-in rack 6, and play a certain supporting role for the plug-in rack 6 moving to the left or right, and the setting height of the guide wheels 11 is lower than the height of the bottom side when the top plate 4 is lifted up.

[0026] like Figure 1-2 As shown, a sensor 12 is also included. A sensor 12 is installed on the left side of the upper part of the mounting frame 2. The sensor is connected to the drive motor 23 through a signal. The two sensors 12 are located on the same line front and back and are symmetrically arranged. The two sensors 12 will emit opposite light. When the right part of the rack 6 transmitted to the left passes through the light emitted by the sensor 12, the sensor will output a signal to the drive motor 23, and the drive motor 23 will stop. At this time, the stop position of the rack 6 is the preset material picking position. The sensor 12 is arranged to enable the rack 6 to be accurately positioned, which is convenient for positioning and taking materials.

[0027] Initially, the support plate 9 is located at the lower position of the lifting group 8, and the slide plate 3 is located at the right extreme position of the synchronous belt group 21. People place the rack 6 with the PCB board on the support plate 9, then start the lifting group 8, and drive the support plate 9 to move upward through the lifting group 8. When the support plate 9 is at the same height as the slide plate 3, the rack 6 on the support plate 9 is pushed to the left onto the slide plate 3. When the rack 6 is pushed to the appropriate position on the slide plate 3, the electromagnet 10 on the slide plate 3 will contact the metal plate 62 on the rack 6. At this time, the electromagnet 10 is energized. Under the action of the current, the electromagnet generates a large magnetic force, which will attract the metal plate 62. The rack 6 is firmly connected to the slide plate 3 through the electromagnet 10 to prevent the rack 6 from being separated from the slide plate 3 by force during movement. When the rack 6 is on the belt of the synchronous belt group 21 When the rack 6 moves downward and moves to the left, the guide wheels 11 on the mounting frame 2 will roll in contact with the front and rear sides of the lower part of the rack 6 to provide certain support for the moving rack 6. When the synchronous belt group 21 drives the rack 6 to the left side of the two sensors 12 on the left, the sensor 12 will transmit a signal to the drive motor 23, the drive motor 23 stops, the synchronous belt group 21 stops conveying, and the stop position of the slide plate 3 is controlled by the sensor 12 to achieve accurate positioning of the rack 6, which is convenient for the positioning and material taking of the material taking robot. When the processing is completed, the driving electric synchronous belt group 21 moves the rack 6 to the rightmost position, cuts off the current of the electromagnet 10, and pulls the rack 6 to the right onto the support plate 9. Finally, the lifting group 8 drives the support plate 9 to move downward, removes the rack 6, and completes the processing.

[0028] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
