[0026] Further speaking:

[0027] As shown in Figures 1-3

[0028] The storage and stacking assembly 2 is installed on the device body 1, the storage and stacking assembly 2 comprises support rods 201 fixed on one side of the device body 1 in symmetrical arrangement, a U-shaped rod one 204 arranged above the two groups of support rods 201, and a plurality of strip rods one 205 fixed inside the U-shaped rod one 204 in equidistant arrangement, an electric push rod 202 is fixedly installed on the upper surface of one end of the support rod 201 through a bolt, a connecting rod 203 is fixed to the output end of the electric push rod 202, the other end of the connecting rod 203 is fixedly connected with the U-shaped rod one 204, a baffle 210 is arranged on one side of the U-shaped rod one 204, and a side plate 206 is fixed on the upper surface of the two groups of support rods 201 close to one side of the device body 1.

[0029] ​In the embodiment, when the circuit board is subjected to film stripping etching, tin stripping, cleaning and drying in the device main body 1, the circuit board is then removed from the device main body 1 and falls on the strip-shaped rod one 205 on the U-shaped rod one 204, and the circuit board is shielded by the baffle 210 to prevent the circuit board from falling off the strip-shaped rod one 205. As the circuit board is continuously conveyed to the strip-shaped rod one 205, the electric push rod 202 is controlled by the controller to drive the connecting rod 203 to move downward and drive the U-shaped rod one 204 and the strip-shaped rod one 205 to move downward to a certain distance. In this way, the circuit board is continuously stacked on the strip-shaped rod one 205, thereby continuously storing the circuit board without the need for workers to orderly stack and store the circuit board, thereby reducing the labor intensity of the workers, meeting the actual use requirement, and improving the use effect of the device.

[0030] It should be noted that, during the stacking of the circuit board on the strip-shaped rod one 205, the electric push rod 202 is controlled by the controller to move downward by the same distance each time, and the specific downward distance can be programmed according to the actual use requirement.

[0046] It should be noted that when the laser range finder 217 works, the laser range finder 217 emits a very thin laser beam to the support rod 201, and then the photoelectric element receives the laser beam reflected by the target. Then, the timer measures the time from the emission to the reception of the laser beam, and by multiplying this time by the speed of light and dividing by two, the distance from the observer to the target can be calculated. After reaching the appropriate distance, a data signal is sent to the controller, and the alarm 218 is started.
