[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1

[0021] See also Figures 1 to 4 , which is the first embodiment of the utility model, and this embodiment provides a technical solution: a circuit board exposure processing fixing mechanism, comprising an exposure processing table 1, a clamping plate 3 and a driving structure 5, a circuit board body 2 is placed at the top center of the exposure processing table 1, two clamping plates 3 are symmetrically arranged on the top of the exposure processing table 1, and the driving structure 5 comprises a motor 51, an inner slide groove 52, a bidirectional screw 53, a nut slider 54 and a connecting block 55, the inner slide groove 52 is opened inside the exposure processing table 1, the motor 51 is installed on one side surface of the exposure processing table 1, the bidirectional screw 53 is rotatably installed on the inner side of the inner slide groove 52, two nut sliders 54 are slidably installed in the inner slide groove 52, and the bidirectional screw 53 passes through the nut slider 54, the top of the nut slider 54 is symmetrically welded and fixed with two connecting blocks 55, and the top surface of the exposure processing table 1 is opened. A strip slide 56 corresponding to the connecting block 55 is provided, and the top of the connecting block 55 passes through the strip slide 56 to the top of the exposure processing table 1. A disassembly and assembly mechanism 6 is provided between the connecting block 55 and the clamping plate 3. The disassembly and assembly mechanism 6 includes a connecting plug block 61 welded and fixed on the top surface of the connecting block 55. The surface of the clamping plate 3 is penetrated with a socket 62 for the connecting plug block 61 to pass through. The top of the connecting plug block 61 passes through the top of the clamping plate 3. The disassembly and assembly mechanism 6 also includes a rotating clip 63 rotatably installed on the top surface of the clamping plate 3, and a strip notch 64 corresponding to the rotating clip 63 is provided on one side surface of the connecting plug block 61. The end of the rotating clip 63 is screwed into the strip notch 64 to limit the clamping plate 3. Subsequently, the end of the rotating clip 63 only needs to be screwed out of the strip notch 64 to quickly remove the clamping plate 3 for replacement.

[0022] Among them, the output end of the motor 51 passes through the inner side of the inner slide groove 52 and is connected to the bidirectional screw 53. The thread directions at both ends of the bidirectional screw 53 are opposite, and the bidirectional screw 53 is threadedly connected to the nut slider 54. When the motor 51 is started later, the bidirectional screw 53 will be driven to spin. Because the thread directions at both ends of the bidirectional screw 53 are opposite, the two nut sliders 54 will slide towards each other when the bidirectional screw 53 spins, and finally the two clamping plates 3 are used to clamp and fix the circuit board body 2, thereby ensuring the stability of the circuit board body 2 during the subsequent exposure process.

[0023] The disassembly and assembly mechanism 6 further comprises a spring slot 65, a spring 66 and a telescopic bead 67. The spring slot 65 is arranged inside the top end of the connecting plug 61, and a telescopic bead 67 is movably installed in the spring slot 65 through the spring 66. A circular slot 68 corresponding to the telescopic bead 67 is arranged on the top surface of the rotating clamping strip 63. The bottom end of the telescopic bead 67 pops out to the inner side of the strip notch 64 and is embedded in the circular slot 68. When the end of the rotating clamping strip 63 is not screwed into the strip notch 64, the bottom end of the telescopic bead 67 pops out to the inner side of the strip notch 64. When the end of the rotating clamping strip 63 is screwed into the inner side of the strip notch 64, the telescopic bead 67 The bottom end of the spring 66 will be squeezed into the circular groove 68 under the pressure of the spring 66, thereby achieving stable limiting of the rotating clip 63 and ensuring the stability of the connection between the splint 3 and the connecting block 55. If the splint 3 needs to be replaced later, it is only necessary to forcefully rotate the end of the rotating clip 63 out of the strip notch 64. When rotating it out, the bottom end of the telescopic clip bead 67 will be gradually squeezed into the spring groove 65 due to the squeezing of the rotating clip 63, and the end of the rotating clip 63 can be smoothly rotated out of the strip notch 64. In the absence of the limiting function of the rotating clip 63, it is only necessary to lift the splint 3 to separate the splint 3 from the connecting plug 61, and the splint 3 can be quickly removed for replacement.

[0024] The top end of the spring 66 is fixed to the upper wall of the spring slot 65 , and the bottom end of the spring 66 is fixedly connected to the top surface of the telescopic bead 67 , thereby ensuring the installation stability of the spring 66 .

[0025] Among them, an ejection hole communicating with the spring groove 65 is opened on the upper wall of the strip-shaped notch 64, and the ejection hole corresponds to the telescopic card bead 67, so that the bottom end of the telescopic card bead 67 can be ejected smoothly.

[0026] A shaft with a T-shaped cross section is fixed on one side of the top surface of the splint 3 relative to each insertion hole 62 , and the rotating clip 63 is rotatably sleeved on the shaft, so that the rotating clip 63 can smoothly rotate on the top of the splint 3 .

[0027] Example 2

[0028] See also Figures 1 to 5 , which is the second embodiment of the utility model. This embodiment is based on the previous embodiment, but differs in that the protective rubber pad 4 can be provided to prevent the subsequent clamping plate 3 from causing squeezing damage to the side of the circuit board body 2 when clamping the circuit board body 2, and the protective rubber pad 4 can be easily replaced later.

[0029] Specifically, a protective rubber pad 4 is installed on one side surface of the splint 3, and a connecting structure is provided between the protective rubber pad 4 and the splint 3, and the connecting structure includes a mounting rubber block 41, a rectangular card slot 42, a mounting hole 31 and a triangular protrusion 32. A plurality of integrated mounting rubber blocks 41 are provided on one side surface of the protective rubber pad 4, both of which are made of rubber material and will undergo elastic deformation when squeezed. A rectangular card slot 42 is provided on the surface of the mounting rubber block 41, and a plurality of mounting holes 31 corresponding to the mounting rubber blocks 41 are provided on the surface of the splint 3, and one side of the mounting hole 31 A triangular protrusion 32 is fixed on the inner wall, and the mounting rubber block 41 is inserted into the mounting hole 31, and the triangular protrusion 32 is snapped into the rectangular slot 42, so that the protective rubber pad 4 can be stably installed on the side of the splint 3, ensuring the installation stability of the protective rubber pad 4. If the protective rubber pad 4 needs to be removed for maintenance and replacement later, it only needs to be pulled sideways with force so that the mounting rubber block 41 is elastically deformed by the squeezing of the triangular protrusion 32 until the mounting rubber block 41 is pulled out of the mounting hole 31, and the protective rubber pad 4 can be easily removed for replacement.
