[0024] The following will describe the present utility model in detail with reference to the embodiments shown in the accompanying drawings:

[0025] As Figure 1-2 shown, in this embodiment, a four-point support cover plate structure is provided, which includes a chassis 10 and a tray box 7. A plurality of lifting driving members are fixedly arranged on the chassis 10. A cover plate frame 6 is erected above the tray box 7. The cover plate frame 6 is movably connected to the tray box 7 in the vertical direction through the lifting driving members. The lifting driving members control the up and down movement of the cover plate frame 6 relative to the tray box 7. A translation assembly is further installed at the bottom of the cover plate frame 6. The cover plate frame 6 is movably connected to the tray box 7 in the horizontal direction through the translation assembly. The translation assembly controls the front and back movement of the cover plate frame 6 relative to the tray box 7. The translation assembly is installed on the lifting driving member, that is, the lifting driving member will control the lifting of the translation assembly while controlling the lifting of the cover plate frame 6.

[0026] When it is necessary to place the PCB board, the lifting driving member controls the translation assembly and the cover plate frame 6 to move upward together. After moving in place, the front and back cylinders 4 (mentioned below) in the translation assembly will control the cover plate frame 6 to move forward relative to the connecting side plate 2 (mentioned below) and the tray box 7.

[0027] After placing the PCB board, cover the PCB board on the cutting window 11 of the fixture transition board 8. The front and rear cylinders 4 work first, controlling the cover plate frame 6 to move backward. Subsequently, the lifting cylinder 1 starts to work, controlling the translation assembly and the cover plate frame 6 to move downward to press the fixture cover plate 9 onto the PCB board. Specifically, when the fixture cover plate 9 is pressed onto the PCB board, the cutting window 11 opened on the fixture cover plate 9 is located above the cutting window 11 of the fixture transition board 8. So that the tool can cut the PCB board through the fixture cover plate 9, and the remaining material after the PCB board is cut will fall from the cutting window 11 of the fixture transition board 8.

[0028] In this embodiment, the lifting driving member is the lifting cylinder 1, and the lifting cylinders 1 are respectively arranged at the four top corners of the chassis 10, so that the fixture cover plate 9 can move downward smoothly and the pressing force at each point is consistent when pressing. The cylinder body of the lifting cylinder 1 is fixedly arranged on the chassis 10, and the piston rod of the lifting cylinder 1 is fixedly connected to the translation assembly. The translation assembly includes a pair of connecting side plates 2, and the connecting side plates 2 are fixedly connected to the top end of the piston rod.

[0029] The fixture transition board 8 is fixedly arranged on the top of the tray box 7, and the cover plate frame 6 is also fixedly provided with the fixture cover plate 9. The fixture transition board 8 is used to place the PCB board to be processed, and the fixture cover plate 9 cooperates with the fixture transition board 8 to press the PCB board, and the cover plate frame 6 is used to limit the movement of the PCB board in the horizontal direction. Both the fixture cover plate 9 and the fixture transition board 8 are provided with cutting windows 11.

[0030] In this embodiment, the translation assembly includes a pair of connecting side plates 2. Linear guides 3 are respectively installed on both sides of the bottom of the cover plate frame 6. The cover plate frame 6 is slidably connected to the connecting side plates 2 through the linear guides 3. A cylinder support block 12 is fixedly arranged on one of the connecting side plates 2, and the front and rear cylinders 4 are installed on the cylinder support block 12. The piston rod of the front and rear cylinders 4 is fixedly connected to the cover plate frame 6. Specifically, a fixed sheet metal 5 is fixedly arranged at the end of the piston rod of the front and rear cylinders 4, and the front and rear cylinders 4 are fixedly connected to the cover plate frame 6 through the fixed sheet metal 5. When the front and rear cylinders 4 act, they will control the movement of the fixed sheet metal 5, thereby pulling the cover plate frame 6.

[0031] To elaborate further, a pair of connecting side plates 2 are respectively fixedly arranged on the piston rods of a pair of lifting cylinders 1, and the lifting cylinders 1 are arranged in pairs on both sides of the tray box 7. The cylinder block of the front and rear cylinders 4 is fixedly connected to the cylinder support block 12. That is, the lifting cylinders 1 can control the connecting side plates 2 and the front and rear cylinders 4 to move up and down. Specifically, in order for the connecting side plates 2 and the cover plate frame 6 to move smoothly in the vertical direction, therefore, a plurality of linear guide rails 3 are installed between the connecting side walls and the tray box 7 to ensure smooth up and down movement. Specifically, the linear guide rail 3 includes a guide rail and a linear bearing, both of which are prior arts. The installation and working principle of the linear guide rail 3 are well-known to those skilled in the art without any doubt, so no further description will be given.

[0032] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification. For those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
