During the plate processing process, the plate clamping and positioning mechanism is responsible for ensuring the stability and accuracy of the plate during the processing to ensure the quality and precision of the processed products. It is applicable to a wide range of fields.

[0003] In the field of exposure machine production and processing, the exposure machine is a device used to copy graphics, patterns or information from the original plate to a plate coated with photosensitive material. The exposure machine is mainly used for exposure processing of PCB, metal plates, ceramic plates, insulation plates, glass, FPC flexible circuit boards and other plates. In these applications, the plate pressing and positioning mechanism is an indispensable part of the exposure machine.

[0029] In this embodiment, a mounting hole 7 is formed on the mounting seat 1, a connecting portion 8 is formed on the pressing block 3, and a connecting hole matching the rotating shaft 2 is formed on the connecting portion 8. The rotating shaft 2 passes through the connecting hole and is connected to the mounting hole 7.

[0030] Optionally, the connecting portion 8 of the pressing block 3 is connected to the rotating shaft 2 so that it can rotate along the rotating shaft 2, and then the plate can be pressed and positioned by the pressing portion 4 on the pressing block 3, thereby improving the stability and accuracy of the plate processing process and improving the production and processing quality.

[0031] Optionally, corresponding anti-skid pads or protective grooves are provided on the pressing part 4 to improve the pressing stability and reliability of the pressing plate.

[0032] In some embodiments, the pressing portion 4 is a portion of the pressing block 3 used to directly press the plate, and its shape can be designed according to the characteristics of the plate, so as to ensure the pressing effect while reducing damage to the plate. Optionally, a protective pad is bonded to the bottom of the pressing portion 4 to protect the pressing of the plate and reduce indentations or damage.

[0033] In this embodiment, the driving member 6 includes a driving block 61 and a driving source 62. A guide groove 9 is provided on the driving portion 5. A mounting portion 10 is formed on the driving block 61, and the mounting portion 10 is connected to the guide groove 9 through a connecting member 11. The connecting member 11 can be slidably arranged along the guide groove 9. The driving source 62 is installed on the base, and the driving end of the driving source 62 passes through the base to be connected to the driving block 61.

[0034] Optionally, the driving block 61 is connected to the guide groove 9 on the clamping block 3, so that when the driving source 62 drives the driving block 61 to move, the driving block 61 can rotate the clamping block 3 under the action of the rotating shaft 2 through the connecting piece 11, thereby completing the clamping and positioning action of the clamping block 3 on the plate, thereby improving the stability and reliability of the drive.

[0035] Optionally, the connecting member 11 can move along the guide slot 9 so that the pressing block 3 can press the plate to produce a sliding gap under the action of the guide slot 9, thereby improving the protection efficiency of the plate and preventing damage caused by a large pressing and clamping force.

[0036] In this embodiment, the driving end of the driving source 62 is the driving shaft 12, and the driving source 62 is a cylinder. The telescopic shaft of the cylinder passes through the base and is connected to the driving block 61, so that the compression and release actions of the compression block 3 can be controlled by the telescopic shaft of the cylinder.

[0037] When the telescopic shaft of the cylinder is extended, the telescopic shaft of the cylinder drives the driving block 61 to rise, and the driving part 5 of the clamping block 3 is linked with the driving block 61, so that under the action of the rotating shaft 2, the clamping part 4 of the clamping block 3 clamps and clamps the plate; conversely, when the telescopic shaft of the cylinder is retracted, the telescopic shaft of the cylinder drives the driving block 61 to descend, and the driving part 5 of the clamping block 3 is linked with the driving block 61, so that under the action of the rotating shaft 2, the clamping part 4 of the clamping block 3 releases the plate, so that the plate can enter the next process.

[0038] In some embodiments, the driving source 62 is an electric cylinder, and the electric cylinder can adjust the clamping force and the clamping position at any time according to the thickness of the plate to meet the clamping requirements of different plates.

[0039] In this embodiment, the pressing block 3 is set at an angle between the pressing portion 4 of the pressing block 3 and the base under the rotation of the connecting portion 8, and the cross section of the pressing block 3 is "T" shaped. A pressing area 13 is formed between the bottom surface of the pressing portion 4 of the pressing block 3 and the upper surface of the mounting seat 1. The pressing area 13 formed by the gap between the pressing portion 4 and the mounting seat 1 can facilitate the entry and exit of the plate, so that when the plate enters the pressing area 13, the pressing block can press and position the plate.

[0040] Optionally, under the drive of the driving member 6, the "T"-shaped pressing block 3 acts as a lever to press, position and release the plate.

[0041] The specific installation and use process of this embodiment is as follows: two plate pressing and positioning mechanisms are set, and the two plate pressing and positioning mechanisms are installed at the opposite ends of the lower glass of the exposure machine located at the exposure station. A accommodating cavity is formed inside the mounting seat 1, and the rotating shaft 2 is used to pass through the mounting seat 1 and connect with the connecting portion 8 of the pressing block 3. The pressing block 3 is exposed and set on the lower glass. The driving portion 5 of the pressing block 3 is connected with the driving block 61 by bolts. The cylinder is installed at the bottom of the mounting seat 1, and the telescopic shaft of the cylinder passes through the base and is connected with the driving block 61.

[0042] Specifically, when the exposure machine conveys the sheet into the pressing area 13 through the conveying mechanism, the driving block 61 is driven to rise by the ejection action of the telescopic shaft of the cylinder, and the driving block 61 drives the pressing block 3 to rotate along the rotating shaft 2, that is, the pressing block 3 approaches the surface of the sheet, so that the pressing part 4 on the pressing block 3 presses the sheet against the pressing area 13, thereby completing the pressing and positioning of the sheet, so that the sheet is exposed and processed through the exposure structure of the exposure machine;

[0043] When the exposure is completed, the contraction action of the telescopic shaft of the cylinder drives the driving block 61 to descend, and the driving block 61 drives the clamping block 3 to rotate along the rotating shaft 2, that is, the clamping block 3 is away from the surface of the plate, so that the clamping part 4 on the clamping block 3 is loosened from the plate, so that the plate can enter a process under the transportation of the conveying mechanism of the exposure machine. The cylinder drives the clamping block 3 to press and position the plate, so that the plate is more stable in the production process of the exposure machine, thereby improving the stability of the plate processing position and the production quality.
