[0002] PC board, also known as polycarbonate board, polyester board, and Capron board, is resistant to weak acids and is made of polycarbonate (PC) resin with polycarbonate as the main component. It has the characteristics of high transparency, light weight, impact resistance, sound insulation, heat insulation, flame retardancy, and aging resistance. It is a high-tech, extremely excellent comprehensive performance, energy-saving and environmentally friendly plastic sheet. It is a plastic building material widely used internationally and has advantages that other building decoration materials (such as glass, plexiglass, etc.) cannot match.

[0003] When printing patterns and text on the surface of a PC board using a printing press, in existing printing devices, the PC board is usually placed on a conveyor belt and then printed on the PC board using a printing press. However, this method can only print on one side of the PC board. Some PC boards may need to print text or image information on both sides, which makes it difficult for existing devices to print on both sides of the PC board at one time, thereby failing to improve the efficiency of double-sided printing of the PC board. Therefore, a printing press for PC board processing is proposed. Utility Model Content

[0026] Example

[0027] Reference Figure 1-Figure 4 , which is an embodiment of the present utility model, provides a printing machine for PC board processing, comprising: a printing unit 100 and an adjustment unit 200;

[0028] The printing unit 100 includes a printing table 101 and a gantry 102 fixedly mounted on top of the printing table 101. A printing machine 103 is fixedly mounted on the top of the inner wall of the gantry 102. An electric slide 104 is fixedly mounted on the top of the printing table 101. A support plate 105 is fixedly connected to one side of the output end of the electric slide 104.

[0029] The adjustment unit 200 includes a door-shaped plate 201 rotatably connected to one side of the support plate 105, a drive motor 202 is fixedly installed on one side of the support plate 105, the output end of the drive motor 202 passes through the support plate 105 and is fixedly connected to the door-shaped plate 201, and two clamping plates 203 passing through the door-shaped plate 201 are slidingly provided on the side wall of the door-shaped plate 201, a fixed plate 204 is fixedly connected to one side of the door-shaped plate 201, a servo motor 205 is fixedly installed on one side of the fixed plate 204, the output end of the servo motor 205 passes through the fixed plate 204 and is fixedly connected to the forward and reverse screw rods 206, the forward and reverse screw rods 206 pass through the two clamping plates 203 and are threadedly connected to the two clamping plates 203.

[0030] The electric slide 104 can drive the support plate 105 to move. Before printing, the electric slide 104 moves the door plate 201 to the side away from the door frame 102, and then the servo motor 205 drives the positive and negative screw rods 206 to rotate, and the two clamping plates 203 are respectively threaded on the two ends of the positive and negative screw rods 206, and the positive and negative screw rods 206 make the two clamping plates 203 move away from each other, and then the PC board is manually placed between the two clamping plates 203, and then the servo motor 205 drives the positive and negative screw rods 206 to rotate in the opposite direction, so that the two clamping plates 203 clamp the PC board, and then the electric slide 104 drives the support plate 105 to move toward the direction of the door frame 102, so that the PC board is located directly under the printing machine 103, and then the printing machine 103 prints on one side of the PC board, and then the electric slide 104 drives the support plate 105 away from the door frame 102 again, so that the PC board is no longer located under the door frame 102;

[0031] At this time, the driving motor 202 drives the door plate 201 to rotate 180 degrees, so that the PC board is flipped, and then the electric slide 104 moves the PC board to the bottom of the door frame 102, and prints the other side of the PC board through the printing machine 103, thereby quickly performing double-sided printing on the PC board to improve printing efficiency. After printing, the electric slide 104 drives the support plate 105 away from the door frame 102 again, and then drives the forward and reverse screw rods 206 to rotate through the servo motor 205, so that the two clamping plates 203 are away from each other, so that the printed PC board can be taken out.

[0032] In addition, a connecting plate 207 is fixedly connected to one side of the gantry 102 , and two rollers 208 are rotatably connected to one side of the connecting plate 207 .

[0033] Among them, one roller 208 is in contact with the top of the printing table 101. When the support plate 105 is moving, the roller 208 can slide on the printing table 101. The roller 208 can provide auxiliary support to the side of the door-shaped plate 201 away from the support plate 105, thereby improving the stability of the movement of the door-shaped plate 201. When the door-shaped plate 201 is flipped, the connecting plate 207 will also rotate one hundred and eighty degrees, so that the other roller 208 is in contact with the top of the printing table 101. In this way, the two rollers 208 can alternately contact with the printing table 101 to ensure the stability of the door-shaped plate 201.

[0034] Furthermore, the top of the printing table 101 is threadedly connected to a threaded rod 209, the top of the threaded rod 209 is fixedly connected to a support plate 210, the bottom of the printing table 101 is fixedly connected to a collection box 106 that passes through the printing table 101, and one side of the collection box 106 is fixedly connected to a cover plate 107 through a hinge.

[0035] The threaded rod 209 can be rotated by rotating the support plate 210, and the height of the support plate 210 can be raised or lowered by rotating the threaded rod 209. When clamping the PC board, the support plate 210 is rotated according to the thickness of the PC board, and then the PC board is placed on the support plate 210, thereby saving workers' physical strength, so that the workers do not need to hold the PC board all the time. The support plate 210 can also keep the PC board in a horizontal state, so that when the two clamping plates 203 clamp the PC board, the PC board will not tilt, thereby ensuring that the printed image will not be stretched due to the tilt;

[0036] When the PC board is printed, the electric slide 104 moves the support plate 105 toward the collection box 106, so that the PC board is located above the collection box 106, and then the servo motor 205 drives the forward and reverse screw rods 206 to rotate, so that the two clamps 203 move away from each other, and the printed PC board automatically falls into the collection box 106 for storage. The baffle 211 is used to prevent the PC board from sliding out of the collection box 106, so that the PC board can be continuously printed through the collection box 106. When a large number of PC boards are stored in the collection box 106, the baffle 211 is deflected so that it no longer covers the collection box 106, so that the PC boards in the collection box 106 can be taken out at one time.

[0037] Furthermore, baffles 211 are slidably provided on the opposing surfaces of the two plywood 203, and threaded bolts 212 corresponding to the positions of the two baffles 211 are threadedly connected on the same side of the two plywood 203, and a pair of rubber pads 213 are fixedly connected to the opposing surfaces of the two plywood 203, and the thickness of the rubber pads 213 does not exceed the thickness of the baffle 211.

[0038] The centers of the opposing surfaces of the two clamping plates 203 are each provided with a sliding groove that fits the baffle plate 211. The two baffle plates 211 are both located at the center of the clamping plates 203 and can be removed and installed through the sliding groove. When the disc-shaped PC board is clamped, the disc-shaped PC board can be supported by the two baffle plates 211 to improve the stability of the clamping of the disc-shaped PC board, thereby preventing the disc-shaped PC board from sliding down between the two clamping plates 203. In this way, PC boards of various shapes can be printed. The threaded bolt 212 penetrates into the sliding groove of the clamping plate 203 and blocks one side of the baffle plate 211 through the threaded bolt 212, so that the baffle plate 211 will not slide out of the sliding groove of the door-shaped plate 201 during the flipping process of the door-shaped plate 201.

[0039] By rotating the threaded bolt 212 so that it is no longer located in the sliding groove of the clamping plate 203, the baffle 211 can then be removed from the clamping plate 203. The rubber pad 213 can increase the friction between the clamping plate 203 and the PC board, making the clamping of the clamping plate 203 more stable. The rubber pad 213 can also protect the PC board to prevent the PC board from being clamped. The thickness of the rubber pad 213 does not exceed the thickness of the baffle 211, so that the baffle 211 can support the PC board.

[0040] During use, the support plate 105 is moved to a position close to the support disk 210 by the electric slide 104, and then the support disk 210 is rotated to adjust the height of the support disk 210, and the PC board is placed on the support disk 210, and then the servo motor 205 is started to drive the positive and negative screw rods 206 to rotate, so that the two clamping plates 203 automatically clamp the PC board, and then the electric slide 104 drives the support plate 105 to move toward the door frame 102, so that the PC board is located directly under the printing machine 103, and the printing machine 103 prints one side of the PC board, and then the electric slide 104 drives the support plate 105 away from the door frame 102 again, so that the PC board is no longer located under the door frame 102, and then the driving motor 202 drives the PC board to flip, and then the electric slide 104 moves the PC board to the bottom of the printing machine 103 again, and the printing machine 103 prints the other side of the PC board;

[0041] In this way, double-sided printing can be performed quickly on the PC board to improve the printing efficiency. After printing is completed, the electric slide 104 moves the support plate 105 toward the collection box 106, so that the PC board is located above the collection box 106. Then, the servo motor 205 moves the two clamps 203 away from each other, so that the printed PC board automatically falls into the collection box 106 for storage. Then, the electric slide 104 moves the support plate 105 toward the support disk 210, and repeats the above operation to print a new PC. When a large number of PC boards are stored in the collection box 106, the deflection baffle 211 is deflected so that it no longer covers the collection box 106, so that the PC boards in the collection box 106 can be taken out at one time.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
