An L-shaped clamping plate 6 is fixedly installed between the tops of the two slide blocks 4 on the same side, and a positioning assembly 8 is arranged on the upper end of the L-shaped clamping plate 6. By setting the positioning component 8, it is avoided that when the thickness of the circuit board is less than the height of the L-shaped clamping plate 6, the top of the circuit board after clamping does not contact the top wall of the L-shaped clamping plate 6, resulting in poor fixing stability of the circuit board, thereby further improving the stability of the circuit board during processing.

[0021] See also Figure 1 and Figure 3 In the embodiment of the utility model: the transmission assembly 7 includes: a gear shaft 701, a rack 702 and an electric push rod 703. The gear shaft 701 is rotatably installed in the middle position of the bottom of the support plate 3. The surface of the upper end of the gear shaft 701 is provided with a bearing. The inner ring of the bearing is fixedly connected to the upper end surface of the gear shaft 701, and the outer ring of the bearing is fixedly connected to the inside of the support plate 3. The bearing is used to improve the rotation stability of the gear shaft 701. Two racks 702 are provided, and one end of the two racks 702 is respectively fixedly installed on one side of the adjacent connecting plate 5. The surface of one side of the rack 702 is meshed with the surface of one side of the lower end of the gear shaft 701. The electric push rod 703 is fixedly installed on one side of the bottom of the support plate 3, and the output end of the electric push rod 703 is fixedly installed on the surface of one side of the adjacent connecting plate 5. When clamping the circuit board placed on the top of the support plate 3, by starting the electric push rod 703, the output end of the electric push rod 703 pulls the corresponding connecting plate 5 toward the direction of the gear shaft 701. At this time, the connecting plate 5 is meshed with one side of the lower end of the gear shaft 701 through the rack 702 on one side, so that the other side of the lower end of the gear shaft 701 is meshed with the rack 702 on one side of the other connecting plate 5. The two racks 702 drive the two symmetrical connecting plates 5 to move relative to each other, so that the two symmetrical L-shaped clamps 6 clamp the two sides of the circuit board in a centering manner. Since the top of the slider 4 is flush with the top of the support plate 3, after the two L-shaped clamps 6 clamp the circuit board, the bottom surface of the circuit board is placed on the top surface of the support plate 3, so as to avoid the bottom of the circuit board being in a suspended state and affecting the stability of the circuit board processing.

[0022] See also Figure 3In the embodiment of the utility model, a guide sleeve 704 is slidably mounted on the surface of the other end of the rack 702, and the top of the guide sleeve 704 is fixedly connected to the bottom of the support plate 3. The setting of the guide sleeve 704 improves the stability of the movement of the rack 702.

[0023] See also Figure 1-2 In the embodiment of the utility model, the positioning assembly 8 includes an adjusting bolt 801, which is rotatably mounted in the middle position of the top of the L-shaped clamping plate 6 in the vertical direction, and a pressing plate 802 is rotatably mounted at the bottom of the adjusting bolt 801. After the two L-shaped clamping plates 6 are relatively moved to clamp and fix the two sides of the circuit board placed on the top of the support plate 3, the adjusting bolt 801 is rotated to move downward, so that the pressing plate 802 rotatably mounted at the bottom of the adjusting bolt 801 moves downward under the guidance of the guide rod 803, and the top of one side of the circuit board is pressed and positioned, so as to avoid the situation that when the thickness of the circuit board is less than the height of the L-shaped clamping plate 6, the top of the circuit board after clamping does not contact the top wall of the L-shaped clamping plate 6, resulting in poor fixing stability of the circuit board, thereby further improving the stability of the circuit board during processing.

[0024] See also Figure 1-2 In the embodiment of the utility model, the top of the pressing plate 802 is symmetrically fixed with a guide rod 803, and the upper end of the guide rod 803 is movable and penetrates the top of the L-shaped clamping plate 6. When the adjusting bolt 801 is screwed in and out of the top of the L-shaped clamping plate 6 to push the pressing plate 802 downward, the pressing plate 802 is guided by the setting of the guide rod 803 to improve the stability of the movement of the pressing plate 802.

[0025] See also Figure 1 In the embodiment of the utility model, a bearing is arranged on the surface of the lower end of the adjusting bolt 801, and the inner ring of the bearing is fixedly connected to the surface of the adjusting bolt 801, and the outer ring of the bearing is fixedly connected to the inside of the pressing plate 802.

At this time, the connecting plate 5 is meshed with one side of the lower end of the gear shaft 701 through the rack 702 on one side, so that the other side of the lower end of the gear shaft 701 is meshed with the rack 702 on one side of the other connecting plate 5. The two racks 702 drive the two symmetrical connecting plates 5 to move relative to each other, so that the two symmetrical L The two sides of the circuit board are clamped by the L-shaped clamping plates 6, and because the top of the slider 4 is flush with the top of the support plate 3, after the two L-shaped clamping plates 6 clamp the circuit board, the bottom surface of the circuit board is placed on the top surface of the support plate 3, and the adjusting bolt 801 is rotated to move downward, so that the pressing plate 802 installed at the bottom of the adjusting bolt 801 moves downward under the guidance of the guide rod 803, and the top of one side of the circuit board is pressed and positioned.
