[0023] Embodiment 1

[0024] Provide a circuit board size detection device:

[0025] An image measuring instrument 11 is installed on the pallet 10, a lining plate 20 extending laterally is arranged above the pallet 10, and a placement component 30 includes two sets of vertical frames 31 movably penetrated on the pallet 10, and the two sets of vertical frames 31 are spaced apart to form a detection area for the image measuring instrument 11 to shoot.

[0026] The image measuring instrument 11 can perform size detection after photographing the circuit board in the detection area. The image measuring instrument 11 can be a fully automatic image measuring instrument 11 selected from the market to realize the detection of various sizes of the circuit board, such as the total length, line, circle, diameter, radius, angle, etc.

[0027] Each set of vertical frames 31 is slidably connected to a carrier plate 33, a guide rail 32 is provided on the top of the vertical frame 31, and a slider slidably engaged with the guide rail 32 is provided on the carrier plate 33. The two sets of carrier plates 33 can be inserted into the detection area close to each other or separated from the detection area away from each other. There are multiple straws 40, and the multiple straws 40 are respectively arranged on the lining plate 20 through movable components 50. A suction source 41 is installed on each set of straws 40. The suction source 41 is used to generate negative pressure at the bottom of the straw 40 to adsorb the circuit board. The suction source 41 is preferably a micro air pump.

[0028] The two groups of carrier plates 33 can be inserted into the inspection area close to each other for temporarily placing circuit boards. At this time, the two groups of carrier plates 33 block the image measuring instrument 11, and the image measuring instrument 11 does not perform measurements. When the two groups of carrier plates 33 move away from each other and leave the inspection area, the circuit boards are adsorbed on the multiple straws 40, and the image measuring instrument 11 takes pictures and measures the circuit boards.

[0029] Specifically, the circuit board is first placed on the two groups of carrier plates 33 inserted into the detection area, and then the two groups of vertical frames 31 are pushed to drive the carrier plates 33 to move upward, so that the placed circuit board contacts the suction tube 40, and the pump source generates negative pressure at the bottom of the suction tube 40 to adsorb the circuit board, so that the two groups of carrier plates 33 are moved away from each other and out of the detection area, and finally the circuit is photographed and tested by the image measuring instrument 11, and multiple suction tubes 40 adsorb the same plane of the circuit board, so that the circuit board remains straight during detection, ensuring the accuracy of size detection;

[0030] After the detection is completed, the two groups of carrier plates 33 are inserted into the detection area close to each other, and the pump source stops at the bottom of the suction tube 40 to generate negative pressure, so that the circuit board is supported by the two groups of carrier plates 33, and then the two groups of vertical frames 31 are reset downward. At this time, the circuit board after the detection is completed can be replaced, thereby achieving rapid detection of the circuit board.

[0031] Embodiment 2

[0032] Provide a circuit board size detection device:

[0033] A beam 34 is disposed at the bottom of the two groups of vertical frames 31 , and a telescopic source 35 is installed on the support plate 10 , and a movable rod of the telescopic source 35 is connected to the beam 34 .

[0034] The telescopic source 35 is preferably an electric cylinder body, and the two sets of vertical frames 31 can be driven to move vertically by the telescopic movable rod of the electric cylinder body, thereby moving the position of the circuit board.

[0035] A baffle 331 is respectively disposed at one end of the two groups of carriers 33 that are away from each other. A fence 332 is disposed on both sides of the baffle 331 . The baffle 331 and the fence 332 can prevent the circuit board from falling off the carrier 33 .

[0037] Provide a circuit board size detection device:

[0038] The movable component 50 includes a shaft rod 51 rotatably connected to the lining plate 20 , a telescopic rod 52 is connected to the bottom of the shaft rod 51 , an end of the telescopic rod 52 away from the shaft rod 51 is connected to the straw 40 , and an adjusting column 53 is screwed to the telescopic rod 52 , which can be against the lining plate 20 .

[0039] The telescopic rod 52 can be stretched or retracted to adjust the lateral position of the straw 40, and the telescopic rod 52 can be rotated to adjust the circumferential position of the straw 40. Therefore, the position of the straw 40 can be adjusted according to the structure of different circuit boards, so that multiple straws 40 can be adsorbed on the same plane of the circuit board, with good adaptability. After adjusting the positional relationship between the telescopic rod 52 and the shaft rod 51, the adjusting column 53 can be tightened to abut against the lining plate 20, so that the telescopic rod 52 will no longer rotate, and the straw 40 adsorbs the circuit board with good stability.

[0040] Each group of straws 40 is provided with a spotlight (not shown in the figure) for generating a light spot on the circuit board to indicate the position where the straws 40 are adsorbed. A rubber ring 42 is provided at the bottom end of each group of straws 40 .
