Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0030]It should be noted that when an element is referred to as being “disposed on” or “fixed on” another element, it may be directly on another element or there may be an intervening element. When an element is referred to as being "fixed on" another element, or "fixedly connected" to another element, it may be detachably fixed or non-detachably fixed therebetween. When an element is referred to as being "connected" or "rotatably connected" to another element, it can be directly connected to the other element or intervening elements may also be prese...

Abstract

The invention discloses an exposure machine and a clamping device for a circuit board. The clamping device for the circuit board comprises a support member which is provided with a first guiding channel and a second guiding channel, a telescopic member provided with a telescopic end, a clamping member which includes a connecting end and a clamping end opposite to the connecting end, and a first transmission member, wherein one end of the first transmission member is rotatingly connected to the telescopic end and cooperates to form a first rotating structure, the other end of the first transmission member is rotatingly connected to the connecting end and cooperates to form a second rotating structure, the first rotating structure can reciprocate along the length direction of the first guiding channel, and the second rotating structure can reciprocate along the length direction of the second guiding channel. The clamping device of the circuit board does not affect the exposure quality of the circuit board, thus, the exposure quality of the exposure machine using the clamping device for the circuit board is high, and the production quality of the circuit board can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of circuit board clamping, in particular to an exposure machine and a circuit board clamping device. Background technique [0002] During the production process of the circuit board, in order to transfer the negative image to the circuit board, the circuit board needs to be exposed. When exposing the circuit board, it is necessary to accurately position the circuit board, usually by means of a clamping device to perform good clamping and positioning of the circuit board. When it is necessary to expose the circuit board, the traditional method is to use two transparent glass plates to clamp and position the entire circuit board and then transport the circuit board to the exposure device. The exposed parts are subjected to exposure processing. When foreign matter remains on the glass or the glass is scratched, it will affect the exposure quality of the circuit board, and then affect the production quality of...
