[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] Please refer to the embodiments of this utility model. Figures 1 to 7 A printing plate exposure machine includes a worktable 1, a top cover 2 rotatably connected to the top of the worktable 1, a flexible hose 3 fixedly connected to the top of the top cover 2, a lock head assembly detachably mounted on the front side of the top cover 2, and a clamping and locking assembly mounted on the front side of the worktable 1. The lock head assembly and the clamping and locking assembly are arranged adjacent to each other. The lock head assembly includes a lock head post 43, and the clamping and locking assembly includes a moving plate 54, a swing plate 56, and a magnetic clamping block 59. The lock head post 43 presses against the moving plate 54 and engages with it. The lock head post 43 swings through the swing plate 56 to magnetically attract the magnetic clamping block 59 onto the lock head post 43.

[0029] The following describes the lock assembly; please refer to it. Figures 1 to 5 The lock assembly includes a fixing member 41, which is detachably attached to the surface of the upper cover 2. A lock cylinder post 43 is fixedly connected to the bottom of the fixing member 41, and a bolt 42 is threadedly connected to the side of the fixing member 41. The fixing member 41 is installed on the side of the upper cover 2 by the bolt 42. A disc 44 is fixedly connected to the bottom of the lock cylinder post 43. A return spring 45 is fixedly connected inside the disc 44. A baffle 46 is fixedly connected to the end of the return spring 45 away from the disc 44. The baffle 46 is slidably connected inside the disc 44 and is clamped inside the clamping and locking assembly. The lock cylinder post 43 is made of metal and magnetically engages with the clamping and locking assembly to lock the upper cover 2.

[0030] The following clamping and locking components are disclosed; please refer to them. Figures 1 to 3 and Figures 6 to 7 The clamping and locking assembly includes a rectangular plate 51, a fixed post 52 fixedly connected to the bottom of the rectangular plate 51, a telescopic post 53 slidably connected inside the fixed post 52, a movable plate 54 fixedly connected to the top of the telescopic post 53, a movable post 55 fixedly connected to both ends of the movable plate 54, a first groove 541 formed on the surface of the movable plate 54, a sliding groove 542 formed on the first groove 541, and a baffle 46 fitted inside the sliding groove 542 to lock the locking assembly.

[0031] The following details the specific structure of workbench 1 to facilitate the normal operation of the exposure machine. Please refer to this information. Figures 1 to 7 The clamping and locking assembly includes a pin 58, which is fixedly connected to the inner cavity of the rectangular plate 51. A swing plate 56 is rotatably connected to the pin 58. A second groove 57 is provided in the swing plate 56. A magnetic clamping block 59 is fixedly connected to the top of the swing plate 56. The magnetic clamping block 59 and the locking pin 43 magnetically engage to lock the upper cover 2. The side of the baffle 46 away from the return spring 45 is arc-shaped. Two sets of return springs 45 and baffles 46 are symmetrically arranged along the center of the disc 44. The moving pin 55 is slidably connected to the second groove 57 of the swing plate 56. The magnetic clamping block 59 is semi-circular. The worktable 1 is divided into a control panel, which controls the closing of the upper cover 2. An air pump is provided inside the worktable 1. The air pump and the hose 3 are fixedly connected. The end of the hose 3 away from the air pump is fixedly connected to the surface of the upper cover 2.

[0032] Working principle: First, the worker installs the fixing part 41 and the locking pin 43 on the side of the upper cover 2 with bolts 42. Then, the clamping and locking assembly is installed on the side of the worktable 1, and two sets of the locking assembly and the clamping and locking assembly are symmetrically arranged.

[0033] To ensure the proper functioning of the exposure machine, the operator first checks the vacuum pump to ensure it is working correctly, and ensures that the glass table and rubber blanket are free of dust and debris. Next, the top cover 2 of the exposure machine is opened, and the film sheet is placed accurately on the printing plate with the emulsion side down, ensuring that the image and text are aligned with the positioning marks on the printing plate. This guarantees accurate positioning of the image and text on the printing plate. Then, the top cover 2 is closed. Please refer to the following procedures. Figure 6 and Figure 7When the upper cover 2 is closed, it will move the locking pin 43 and the disc 44 into the first groove 541. When the baffle 46 moves to the edge of the first groove 541, it will retract into the disc 44. When the disc 44 is completely aligned with the moving plate 54, the baffle 46 will lose its pressing force and will engage with the sliding groove 542. Then, as the disc 44 continues to move downward, it will move the moving plate 54 downward. The downward movement of the moving plate 54 will cause the telescopic pin 53 to slide inside the fixed pin 52. During the downward movement of the moving plate 54, it will also cause the moving pin 55 to move downward synchronously. The movement of the two moving pins 55 will then cause the two openings in the two swing plates 56 to move downward. The two movable columns 55 slide inside the second groove 57, causing them to move from the middle of the two second grooves 57 to the bottom of the two second grooves 57 respectively. During the sliding process of the two movable columns 55, they will drive the two swing plates 56 to rotate around the center of their respective pins 58, causing the two swing plates 56 to swing closer to each other. At the same time, the two swing plates 56 swinging closer to each other will drive the two magnetic clamping blocks 59 to move closer to each other, so that the two magnetic clamping blocks 59 clamp and magnetically secure the locking column 43, thereby improving the closing effect of the top cover 2 when closed, reducing the movement of the locking column 43 during vacuum evacuation, and ensuring the quality of subsequent plate exposure.

[0034] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
