Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0023] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "page", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0025] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed", "provided with", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0026] Refer to the attached Figure 1-4 An exposure machine for LCD screen production includes an exposure machine body 1, an exposure lamp 2 is arranged in the exposure machine body 1, and a material discharge plate 3 is located below the exposure machine body 1, a sealing plate 4 is fixedly installed at the front end of the material discharge plate 3, and the sealing plate 4 matches the through slot 101 opened on the side wall of the exposure machine body 1, and a connecting plate 5 is fixedly installed at the bottom of the material discharge plate 3, and the connecting plate 5 is connected to a first electric push rod 6 assembled in the exposure machine body 1, and the first electric push rod 6 is distributed along the extension direction of the through slot 101;

[0027] It also includes two clamping plates 7, which are transmission-connected to the connecting plate 5, so that the two sides of the discharge plate 3 are close to or away from each other.

[0028] In this embodiment, after the first electric push rod 6 is started, the connecting plate 5 can be driven to move, and the unloading plate 3 keeps moving synchronously to pass through the through slot 101 and be placed outside the exposure machine body 1, so that the exposure piece to be processed can be placed on the unloading plate 3. Similarly, by driving the first electric push rod 6, the unloading plate 3 can enter the exposure machine body 1 again and be processed by the exposure lamp 2;

[0029] The two clamping plates 7 are transmission-connected with the connecting plate 5. When the discharge plate 3 enters the exposure machine body 1, the two clamping plates 7 will approach each other to clamp the exposure piece and limit it. When the discharge plate 3 is placed outside the exposure machine body 1, the two clamping plates 7 will move away from each other to release the clamped exposure piece, thereby automatically completing the limiting of the exposure piece, reducing labor intensity and improving overall work efficiency.

[0030] The sealing plate 4 is used to close the through slot 101 to prevent the light of the exposure lamp 2 from leaking to the outside of the exposure machine body 1 .

[0031] Considering that the connecting plate 5 cannot pass through the through slot 101 when the unloading plate 3 discharges materials, the connecting plate 5 is arranged near the end of the unloading plate 3 to ensure that the unloading plate 3 has enough space to be placed outside the exposure machine body 1.

[0032] The clamping plate 7 is L-shaped and includes a vertical portion 701 and a horizontal portion 702 placed on the top of the discharge plate 3. One end of the vertical portion 701 is hingedly connected to the connecting plate 5 through a connecting rod 8, and the other end is fixedly installed with a guide slide rod 9, which is slidably connected to a guide slide sleeve 10 arranged in the exposure machine body 1.

[0033] In this embodiment, when the first electric push rod 6 drives the connecting plate 5 to move, the connecting rod 8 pulls the vertical part 701, and then cooperates with the sliding of the guide sliding rod 9 in the guide sliding sleeve 10 to drive the two vertical parts 701 to be relatively close or away from each other, and the two horizontal parts 702 maintain synchronous movement on the top of the discharge plate 3, thereby achieving the clamping limit or loosening of the exposure part.

[0034] The second electric push rods 11 are mounted on the opposite sides of the horizontal portion 702 , and the extension plates 12 are fixedly mounted on the telescopic ends of the second electric push rods 11 .

[0035] In this embodiment, after the second electric push rod 11 drives the extension plate 12 to move, the distance between the two extension plates 12 can be changed, so that it can clamp and limit the exposure parts with different width specifications.

[0036] A third electric push rod 14 is mounted on the top of the unloading plate 3 . The third electric push rod 14 and the first electric push rod 6 are distributed in the same direction, and a limit plate 13 is fixedly mounted on the telescopic end.

[0037] In this embodiment, after one end of the exposure piece is abutted against the limit plate 13, the exposure piece can be limited to just below the exposure lamp 2 by the clamping and limiting of the two extension plates 12 to ensure the exposure effect, and after the third electric push rod 14 is started, the position of the limit plate 13 can be changed so that it can adapt to exposure pieces of different length specifications.

[0038] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.

[0039] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art.
