[0005] The conveyor line includes a first guide rail, a second guide rail, a first conveyor belt, a second conveyor belt, and a power mechanism. The first conveyor belt is arranged inside the first guide rail through a pulley, the second conveyor belt is arranged inside the second guide rail through a pulley, the power mechanism includes a transmission rod and a motor drivingly connected to the transmission rod through a chain, and transmission pulleys for the first conveyor belt and the second conveyor belt to wind around are arranged on the transmission rod.

[0006] The conveyor line further includes two spacing adjustment mechanisms for adjusting the distance between the first guide rail and the second guide rail. The two spacing adjustment mechanisms are respectively arranged at the head and tail ends of the first guide rail and the second guide rail. The spacing adjustment mechanism includes an adjustment lead screw with positive and negative threads and a support guide rail. The positive thread of the adjustment lead screw is screwed to the first guide rail, and the negative thread of the adjustment lead screw is screwed to the second guide rail.

[0016] Please refer to Figures 1 to 4 , a preferred embodiment of the present invention, a control circuit board current and voltage detection device, includes a conveyor line 10 for conveying products, a probe detection tooling 20 for detecting the current and voltage of products, a lifting mechanism 30 for pushing the detection tooling 20 to detect the products conveyed on the conveyor line 10, at least one set of positioning mechanisms 40 disposed on one side of the conveyor line 10 for positioning any product on the conveyor line 10, and a rejection mechanism 50 disposed on one side of the conveyor line 10 for rejecting unqualified products. The products B to be detected are conveyed one by one through the conveyor line 10. The positioning mechanism 40 positions the product B directly below the probe detection tooling 20, so that the lifting mechanism 30 pushes the probe detection tooling 20 down to detect the voltage and current of the positioned product. The qualified products pass through the rejection mechanism 50, and the unqualified products are pushed off the conveyor line 10 by the rejection mechanism 50, that is, the lifting mechanism 30 pushes the probe detection tooling 20 down to contact the positioned product, and the probe detection tooling 20 detects the voltage and current of the positioned product. When the product is detected as qualified, the qualified product is released by the positioning mechanism 40. When the product is detected as unqualified, the unqualified product is pushed out of the conveyor line 10 by the rejection mechanism 50.

[0017] In this embodiment, the conveyor line 10 includes a first guide rail 11, a second guide rail 12, a first conveyor belt 13, a second conveyor belt 14, and a power mechanism 15. The first conveyor belt 13 is arranged inside the first guide rail 11 through pulleys, and the second conveyor belt 14 is arranged inside the second guide rail 12 through pulleys. The power mechanism 15 includes a transmission rod 151 and a motor 152 that is drivingly connected to the transmission rod 151 through a chain. Transmission belt pulleys 153 for the first conveyor belt 13 and the second conveyor belt 14 to wind around are arranged on the transmission rod 151, so as to drive the first conveyor belt 13 and the second conveyor belt 14 to rotate through the transmission rod 151, thereby achieving the effect of conveying products.

[0018] In this embodiment, the conveyor line 10 further includes two spacing adjustment mechanisms 16 for adjusting the distance between the first guide rail 11 and the second guide rail 12. The two spacing adjustment mechanisms 16 are respectively arranged at the head and tail ends of the first guide rail 11 and the second guide rail 12 to support the first guide rail 11 and the second guide rail 12. The spacing adjustment mechanism 16 includes an adjustment lead screw 161 with right-hand and left-hand threads and a support guide rail 162. The right-hand thread of the adjustment lead screw 161 is screwed to the first guide rail 11, and the left-hand thread of the adjustment lead screw 161 is screwed to the second guide rail. The first guide rail 11 and the second guide rail 12 are installed on the support guide rail 162 through sliders, so that when the adjustment lead screw 161 is rotated, the first guide rail 11 and the second guide rail 12 move towards or away from each other on the support guide rail 162, thereby achieving the effect of adjusting the distance between the first guide rail 11 and the second guide rail 12.

[0019] In this embodiment, the lifting mechanism 30 includes a fixed frame 31 fixed above the conveyor line 10, a lifting cylinder 32 installed upside down on the fixed frame 31, and a lifting plate 33 located outside the fixed frame 31 and fixed to the cylinder shaft of the lifting cylinder 32. The probe detection tooling 20 is fixed on the lifting plate 33, and the lifting cylinder 32 drives the probe detection tooling 20 to perform a lifting motion above the conveyor line 10.

[0020] It is worth mentioning that the probe detection tooling 20 is a conventional fitting or technical means in the art, and is a quick-change type probe detection tooling plate for electrical component detection. It integrates a probe group and is connected to the probes through a wiring harness, and completes the detection of voltage and current by contacting the relevant contacts of the control circuit board through the probes.

[0021] In this embodiment, the first guide rail 11 and the second guide rail 12 are correspondingly provided with a discharge notch A, and the rejection mechanism 50 includes a first photoelectric detector 51 and a rejection cylinder 52, a push plate 521 is installed on the cylinder shaft of the rejection cylinder 52, and the rejection cylinder 52 is fixed on one side of the discharge notch A, and the first photoelectric detector 51 is fixed on the top of the rejection cylinder 52. When the product detected by the probe detection tooling is unqualified, it will first pass through the discharge notch A. When the first photoelectric detector 51 detects that the unqualified product is located in the discharge notch A, the rejection cylinder 52 pushes the push plate 521 to push the unqualified product out of the discharge notch A.

[0022] In this embodiment, the positioning mechanism 40 includes a mounting frame 41, a positioning hook 42 flippably mounted on the top of the mounting frame 41, and a positioning cylinder 43 fixed to the bottom of the mounting frame 41 for pushing the positioning hook 42 to flip over in the mounting frame 41. The positioning mechanism 40 also includes a second photoelectric detector 44 for detecting whether the product is located directly below the probe detection tooling 20. When the second photoelectric detector 44 detects that the product is located directly below the probe detection tooling 20, the positioning cylinder drives the positioning hook to flip and position the product directly below the probe detection tooling 20 to facilitate the descent of the probe detection tooling 20 for voltage and current detection.

[0023] What the present invention aims to achieve is to convey the control circuit boards one by one to the bottom of the probe detection tooling through the conveyor line, and the products that are detected as qualified by the probe detection tooling are conveyed to the next process through the conveyor line. Conversely, if the products are detected as unqualified by the probe detection tooling, the unqualified products are pushed out of the conveyor line from the discharge notch by the rejection cylinder, so as to achieve the effect of uninterrupted and continuous voltage and current detection of the products, thereby improving production efficiency.

[0024] The embodiment and drawings of the present invention are only for illustrating the design concept of the present invention, and the protection scope of the present invention should not be limited to this embodiment.

[0025] It can be seen from the above description that the design purpose of the present invention can be effectively implemented. The embodiment part shows the purpose of the present invention and the implementation function and structural theme, and includes other equivalent replacements.

[0026] Therefore, the rights of the present invention include other equivalent implementations, and the specific scope of rights refers to the claims.
