Problems solved by technology
[0003] In order to prevent the circuit board from shifting during the moving process, the circuit board is usually positioned on the exposure machine platform by sucking the nozzle. However, due to the different appearance of the circuit board, there are thin and thick, warped and curved, etc. Etc., using the method of adsorption and positioning of the suction nozzle, the adsorption and positioning are unstable. During the moving process, the circuit board is still prone to displacement and misalignment. The moving position of the board is inaccurate, and the error is large, which affects the alignment operation of the circuit board after entering the exposure room, resulting in inaccurate exposure and affecting the exposure quality

The invention discloses a clamping device of an exposure machine, which comprises a lifting driving mechanism, a rotary driving mechanism connected to the lifting driving mechanism, and a clamping piece connected to the rotary driving mechanism, the rotary driving mechanism comprises a mounting side plate, a rotation driving air cylinder arranged on the mounting side plate, a rack connected to the output end of the rotation driving air cylinder, a rotating shaft connected to the clamping piece and a gear connected to the rotating shaft and meshed with the rack. According to the clamping device of the exposure machine provided by the invention, the circuit board is stably clamped and positioned on an exposure machine platform, so that the circuit board can synchronously move along with the exposure machine platform, and the phenomena of displacement, dislocation and the like are avoided, so that the accuracy of the moving position of the circuit board is improved, the alignment operation after the circuit board moves into an exposure chamber is improved, and the alignment accuracy is improved, so that the exposure accuracy is improved.
Description
technical field [0001] The invention relates to an exposure machine, in particular to a clamping device for the exposure machine. Background technique [0002] The circuit board exposure process is an important link in the circuit board production process. In the current inner layer circuit board exposure equipment on the market, the circuit board is usually moved to the exposure room by an automatic mechanism, and then the circuit board is aligned. exposure. [0003] In order to prevent the circuit board from shifting during the moving process, the circuit board is usually positioned on the exposure machine platform by sucking the nozzle. However, due to the different appearance of the circuit board, there are thin and thick, warped and curved, etc. Etc., using the method of adsorption and positioning of the suction nozzle, the adsorption and positioning are unstable. During the moving process, the circuit board is still prone to displacement and misalignment. The moving ...
