The film pasting process of the circuit substrate mainly comprises the following steps: 1) placing the circuit substrate and the positioning jig connected with the circuit substrate into a material storage mechanism, and moving the circuit substrate and controlling the output of the circuit substrate by the material storage mechanism; 2) the material storage mechanism pushes the circuit substrate to the blanking mechanism, and the blanking mechanism quickly blanks the circuit substrate; 3) the circuit substrate is blanked to a film sticking device, a film supplying device in the film sticking device conveys protective films for a film sticking process, and a film pulling device and an upper jacking device stick the protective films to the surface of the circuit substrate; 4) the film pressing device rolls the surface of the circuit substrate on which the protective film is pasted, so that bubbles between the circuit substrate and the protective film are removed, and the pasting of the protective film is more uniform; 5) the moving device moves the rolled circuit substrate to the blanking device; 6) the blanking device carries out circular blanking on the circuit substrate product to complete the film pasting process of the circuit substrate. With the development of the circuit substrate industry, the circuit substrate film pasting equipment has more and more important position.

When the circuit substrate is blanked, the sucking disc mechanism reaches the position of the circuit substrate, the sucking disc sucks the circuit substrate, then the moving mechanism acts to drive the sucking disc mechanism to reach the blanking position, and the sucking disc mechanism loosens the circuit substrate to complete blanking of the circuit substrate; the whole blanking process needs a plurality of steps of moving the mechanism back and forth, sucking and loosening by the sucking disc mechanism and the like, so that the complexity of the blanking process of the circuit substrate is increased; and the sucking disc mechanism and the moving mechanism can only suck and move one circuit substrate in one blanking process, so that the moving time of the circuit substrate in each blanking is increased, and the blanking efficiency of the circuit substrate is reduced.

The blanking mechanism 12 is in the working process: 1) the material storage pushing assembly 112 pushes the circuit substrates into the blanking box grooves 1232 of the blanking box 123; 2) the blanking driving motor 1211 sequentially drives the blanking driving reducer 1212 and the blanking box 123 connected with the blanking driving reducer to move downwards along the blanking box guide rail 12221; 3) the blanking box 123 moves downwards to drive the circuit substrate embedded in the blanking box groove 1232 to move downwards, and the circuit substrate at the lowest end is contacted with the conveyor belt assembly 124; 4) the conveyor belt assembly 124 drives the circuit substrate contacting with it to move forward, and the blanking driving motor 1211 continues to drive the circuit substrate above to move downward to the position contacting with the conveyor belt assembly 124, so as to complete the blanking process of the circuit substrate.

The blanking mechanism 12 solves the problem that when the circuit substrate is blanked, a sucker mechanism reaches the position of the circuit substrate firstly, the circuit substrate is sucked by a sucker, then the moving mechanism acts to drive the sucker mechanism to reach the blanking position, and the sucker mechanism loosens the circuit substrate to complete the blanking of the circuit substrate; the whole blanking process needs a plurality of steps of moving the mechanism back and forth, sucking and loosening by the sucking disc mechanism and the like, so that the complexity of the blanking step of the circuit substrate is increased; and the sucking disc mechanism and the moving mechanism can only suck and move one circuit substrate in one blanking process, thereby increasing the moving time of the circuit substrate in each blanking and reducing the blanking efficiency of the circuit substrate. By arranging the blanking screw guide rail assembly 122, the blanking box 123 and the conveying belt assembly 124; when the circuit substrate is blanked, only two steps of driving the circuit substrate to move downwards by the blanking box 123 and driving the circuit substrate moved downwards by the conveyor belt assembly 124 are needed, and compared with four steps of driving the suction cup to move downwards, driving the suction cup to move upwards, driving the moving mechanism to move forwards and driving the moving mechanism to move backwards when the suction cup moves and blanks, the steps of blanking the circuit substrate are reduced, and the complexity of the blanking process of the circuit substrate is reduced; meanwhile, the blanking box 123 is provided with a plurality of blanking box grooves 1232, the blanking box grooves 1232 are arranged in a layered manner, and a plurality of circuit substrates are respectively arranged in the blanking box grooves 1232; when the circuit substrates are blanked, the circuit substrate at the lowest layer is firstly contacted with the conveyor belt assembly 124, then the conveyor belt assembly 124 conveys the circuit substrate to the next station to complete the blanking of the circuit substrate at the lowest layer, and then the blanking box 123 directly moves downwards to contact the circuit substrate at the upper layer with the conveyor belt assembly 124 until the circuit substrates in all the blanking box grooves 1232 of the blanking box 123 are blanked; that is, after the feeding of the blanking box 123 is completed, the continuous blanking of a plurality of circuit substrates can be realized in one blanking process, and the intermittent blanking of only a single circuit substrate in one blanking process and the process of moving the circuit substrate every time of blanking are avoided, so that the total moving time of the circuit substrate during the intermittent blanking of the single circuit substrate is reduced, and the blanking efficiency of the circuit substrate is improved.
