The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0032] like Figures 1 to 6 As shown, the present invention is an automated pin test device, comprising: a pin carrier 1, a conveyor belt 2 for driving the pin carrier 1 for conveying, a detection rack 3, a rotating table 4 for transporting the conveyor belt 2, a motor 401 for driving the rotating table 4 to rotate, the motor 401 is preferably a stepping motor, so that the output end of the motor 401 drives the rotating table 4 to rotate 90 degrees at a time, carrier slots 402 are provided on both sides of the rotating table 4, one side of the pin carrier 1 is fixedly connected to a first magnetic block 101, and the carrier slot 4 The inner wall of 02 is fixedly installed with a second magnetic block 4022 that matches the first magnetic block 101. The first magnetic block 101 and the second magnetic block 4022 have opposite magnetic poles and attract each other. When the conveyor belt 2 pushes the pin carrier 1 into the carrier slot 402, the first magnetic block 101 on one side of the pin carrier 1 and the second magnetic block 4022 on the inner wall of the carrier slot 402 are attracted. When the rotating table 4 transports the pin carrier 1 in the carrier slot 402, the pin carrier 1 is prevented from slipping out of the carrier slot 402, thereby improving stability.

[0033] Slide blocks 102 are fixedly installed at both ends of the pin carrier 1, and slide blocks 4021 matching with the slide blocks 102 are opened on both sides of the carrier slot 402. When the pin carrier 1 moves into the carrier slot 402, the slide blocks 102 at both ends of the pin carrier 1 are inserted into the slide blocks 4021 inside the carrier slot 402, further improving the installation stability of the pin carrier 1;

[0034] The end of the carrier slot 402 is chamfered, and the chamfer angle is 45 degrees. The chamfer of the carrier slot 402 guides the movement of the pin carrier 1 when it moves into the carrier slot 402, so as to facilitate the movement of the pin carrier 1 into the carrier slot 402, and the blocking mechanism 5 for intermittent feeding of the pin carrier 1, and the detection component 6 for detecting the pins of the electrical connector on the pin carrier 1;

[0035] The material blocking mechanism 5 includes: a material blocking component 502 for blocking the pin carrier 1, and a transmission component 501 for pushing the material blocking component 502 to block the material;

[0036] The transmission assembly 501 comprises a rotating shaft 5011 fixedly mounted on the rotating table 4, a cam 5012 fixedly mounted on the rotating shaft 5011, arc-shaped protrusions symmetrically arranged on both sides of the cam 5012, and a pressing block 5013 set to be a trapezoidal shape matching the arc-shaped protrusion of the cam 5012, and the arc-shaped protrusion corresponds to the adjacent carrier slot 402. When the arc-shaped protrusion of the cam 5012 presses the pressing block 5013, the interference between the two is reduced. The pressing block 5013 and the push rod 5013 fixedly mounted on the pressing block 5013 14. A push block 5015 is fixedly mounted on the push rod 5014, and the bottom of the push block 5015 is set as an inclined surface of a V-shaped structure. The top of the extrusion rod 5022 is set as an arc that matches the inclined surface of the bottom of the push block 5015. Through the inclined surface of the V-shaped structure at the bottom of the push block 5015, when the push block 5015 moves toward the position of the rotating table 4, the blocking needle 5023 away from the position of the rotating table 4 moves up, and at the same time, the blocking needle 5023 close to the position of the rotating table 4 moves down, thereby blocking the pin carrier 1 transported on the conveyor belt 2. After the wheel 5012 squeezes the squeezing block 5013 to move the pushing block 5015 away from the rotating table 4, the stopper needle 5023 at the position away from the rotating table 4 moves down to between two adjacent pin carriers 1 to separate the two adjacent pin carriers 1. At the same time, the stopper needle 5023 at the position close to the rotating table 4 moves up, so that the separated pin carriers 1 move to the position of the carrier slot 402 under the conveyance of the conveyor belt 2, thereby realizing automatic intermittent conveyance of the pin carriers 1 and improving work efficiency. The first spring sleeved on the push rod 5014 5016, and a positioning block 5017 sleeved on the push rod 5014; the top of the positioning block 5017 is fixedly connected to the top wall of the detection frame 3, one end of the first spring 5016 is fixedly connected to the surface of the positioning block 5017, and the other end of the first spring 5016 is fixedly connected to the surface of the extrusion block 5013. When the protrusion on the cam 5012 is not pressed on the extrusion block 5013, the first spring 5016 is elastically reset after being stressed to push the extrusion block 5013 to move closer to the cam 5012;

[0037] The material blocking assembly 502 is composed of a bracket 5021 fixedly mounted on the detection frame 3, a squeeze rod 5022 penetrating both sides of the bracket 5021, the tops of the two squeeze rods 5022 are respectively placed at the high and low positions of the V-shaped structure slope at the bottom of the push block 5015, a stopper needle 5023 fixedly mounted at the bottom of the squeeze rod 5022 to block the pin carrier 1, a connecting ring 5024 fixedly mounted on the squeeze rod 5022, and a second spring 5025 sleeved on the squeeze rod 5022. One end of the second spring 5025 is fixedly connected to the surface of the connecting ring 5024, and the other end of the second spring 5025 is fixedly connected to the surface of the bracket 5021.

[0038] When testing the electrical connector after the pin insertion, the conveyor belt 2 conveys the electrical connector placed on the pin insertion carrier 1, and the motor 401 drives the rotating table 4 to rotate 90 degrees at a time. When the carrier slot 402 on the rotating table 4 rotates to the end of the conveyor belt 2, the cam 5012 on the rotating shaft 5011 squeezes the squeezing block 5013 so that the squeezing block 5013 drives the pushing block 5015 on the pushing rod 5014 to move away from the rotating table 4, and through the inclined surface setting of the V-shaped structure at the bottom of the pushing block 5015, the blocking needle 5023 away from the rotating table 4 moves down to the two adjacent plug Between the pin carriers 1, two adjacent pin carriers 1 are separated, and at the same time, the pin blocking 5023 near the position of the rotating table 4 is moved up, so that the separated pin carrier 1 moves to the position of the carrier slot 402 under the transportation of the conveyor belt 2, so as to realize automatic intermittent transportation of the pin carrier 1. When the pin carrier 1 transported on the rotating table 4 rotates to the bottom of the detector 601, the detector 601 detects the pin carrier 1, so that the pin carrier 1 on the conveyor belt 2 can be automatically tested in turn, which is easy to operate, improves test efficiency and production capacity, reduces labor intensity and labor costs, and meets market needs.

[0039] The detection assembly 6 includes: a detector 601 for detecting the pins on the electrical connector, an electric cylinder 602 for driving the detector 601 to move, a good product conveying platform 603, a defective product conveying platform 604, a push plate 606 for pushing the pin carrier 1 out of the carrier slot 402, two push plates 606 are provided, which are respectively located at the ends of the good product conveying platform 603 and the defective product conveying platform 604, and are used to push the pin carrier 1 after detection, an electric rod 605 for driving the push plate 606 to move, and a PLC control box 607 fixedly installed on the detection rack 3. The PLC control box 607 is electrically connected to the motor 401, the detector 601, the electric cylinder 602 and the electric rod 605, and the selection of good and defective products detected on the electrical connector is controlled by the PLC.

[0040] When the pin carrier 1 in the carrier slot 402 rotates to below the detector 601, the PLC control box 607 controls the output end of the electric cylinder 602 to push the detector 601 downward to detect the pin carrier 1 to detect whether the product pins are conductive and qualified. When the product is qualified, the electric cylinder 602 drives the detector 601 to move upward, and the push plate 606 at the output end of the electric rod 605 pushes the qualified pin carrier 1 into 403 for transportation to the next process. When the product is unqualified, after the detector 601 moves upward, the motor 401 drives the rotating table 4 to rotate 90 degrees, so that the pin carrier 1 in the carrier slot 402 rotates to the position of the defective product conveying platform 604, and then the push plate 606 at the output end of the electric rod 605 at the position of the defective product conveying platform 604 pushes the unqualified pin carrier 1 into the defective product conveying platform 604 and conveys it to the next process for inspection. It has a high degree of automation and is easy to operate.

[0041] A positioning plate 6011 is fixedly installed on one side of the detector 601, and the positioning plate 6011 is located just below the end of the carrier slot 402. When the detector 601 moves downward, the surface of the positioning plate 6011 on one side of the detector 601 is placed on the surface of the pin carrier 1 in the carrier slot 402, which limits the pin carrier 1 and avoids displacement during pin detection, thereby ensuring the reliability of the test.

[0042] Working principle: When the power is turned on and the electrical connector after the pin is inserted is tested, the conveyor belt 2 conveys the electrical connector placed on the pin carrier 1, and the motor 401 drives the rotating table 4 to rotate 90 degrees at a time. When the carrier slot 402 on the rotating table 4 rotates to the end of the conveyor belt 2, the cam 5012 on the rotating shaft 5011 squeezes the squeezing block 5013 so that the squeezing block 5013 drives the push block 5015 on the push rod 5014 to move away from the rotating table 4, and through the inclined surface setting of the V-shaped structure at the bottom of the push block 5015, the stopper needle 5023 at the position away from the rotating table 4 moves down to between two adjacent pin carriers 1, so that the two adjacent pin carriers 1 are separated, and at the same time, the stopper needle 5023 close to the rotating table 4 moves up, so that the separated pin carrier 1 moves to the position of the carrier slot 402 under the conveyance of the conveyor belt 2, so as to realize the pin loading The tool 1 is automatically intermittently transported. When the pin carrier 1 transported on the rotating table 4 rotates to the bottom of the detector 601, the PLC control box 607 controls the output end of the electric cylinder 602 to push the detector 601 downward to detect the pin carrier 1 to detect whether the product pins are conductive and qualified. When the product is qualified, the electric cylinder 602 drives the detector 601 to move up, and the push plate 606 at the output end of the electric rod 605 pushes the qualified pin carrier 1 into 403 and transports it to the next process. When the product is unqualified, after the detector 601 moves up, the motor 401 drives the rotating table 4 to rotate 90 degrees, so that the pin carrier 1 in the carrier slot 402 rotates to the position of the defective product conveying table 604, and then the push plate 606 at the output end of the electric rod 605 at the position of the defective product conveying table 604 pushes the unqualified pin carrier 1 into the defective product conveying table 604 and transports it to the next process for inspection.
