DETAILED DESCRIPTION

[0013] In order to further understand the features, technical means and specific purposes and functions achieved by the utility model, the utility model will be further described in detail in combination with specific embodiments and drawings.

[0014] In the utility model, unless explicitly defined and limited, the terms "mounting", "connection", "connecting", "fixing" and the like should be understood in a broad sense, for example, can be fixedly connected, can be detachably connected or integrally connected, can be mechanically connected or electrically connected, can be directly connected or indirectly connected through an intermediate medium, or can be connected inside two elements. For ordinary skilled in the art, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.

[0015] Please refer to Figs. 1-2As shown, a clamping structure for a circuit board developing device comprises a fixed seat 17, a first telescopic motor 15, a U-shaped clamping plate 10, a mounting plate 13, two electric push rods 14, a push plate 19, and a rotary drive motor 16. The inner side wall of the U-shaped clamping plate 10 is formed with a circuit board clamping groove, and the push plate 19 is correspondingly arranged in the circuit board clamping groove. The rotary drive motor 16 is fixedly installed on the fixed seat 17, and the power output end of the rotary drive motor 16 is connected with the first telescopic motor 15. The first telescopic motor 15 is connected with the U-shaped clamping plate 10 through a telescopic rod 20 penetrating through the mounting plate 13. The mounting plate 13 is fixedly connected with the U-shaped clamping plate 10 through a connecting rod 18. The two electric push rods 14 are respectively fixedly installed on the opposite sides of the length direction of the mounting plate 13. The power output end of the electric push rod 14 is connected with the fixed push plate 19 through the mounting plate 13 and the U-shaped clamping plate 10.

[0016] The opposite sides of the length direction of the circuit board clamping groove are both provided with soft rubber pads 11. The upper surface and the lower surface of the opposite sides of the circuit board clamping groove are both provided with silica gel pressing blocks 22. The stability of clamping is improved.

[0017] The soft rubber pad 11 is formed with an arc-shaped guide surface 21 close to the opening side, so that the circuit board can enter the circuit board clamping groove better.

[0018] A universal horizontal bubble level 12 is installed on the upper surface of the U-shaped clamping plate 10. When the device is debugged, the horizontal condition of the structure can be detected through the horizontal bubble level 12. If it is found that the structure cannot keep horizontal, it can be adjusted in time. Through such a setting, it is ensured that the U-shaped clamping plate 10 can keep a horizontal state to receive the spraying of developing liquid in the production process, and can also reset to a horizontal state after the spraying of developing liquid is completed, so that the uneven contact between the surface of the circuit board and the developing liquid is avoided, and the developing effect is affected.
