The second connecting frame is connected to the first connecting frame by pulling the rotating frame, and the first moving frame and the second moving frame are jointly pushed to move synchronously. When the second moving frame moves up, the pressing plate fixes the chip resistor inside the conveying slideway.

The pneumatic suction cup is used to absorb the chip resistors, so that the belt slide can carry and stack the chip resistors. This automated process greatly reduces the time and labor of manual operation, while ensuring a continuous and stable working state, which is not affected by human fatigue or distraction, thereby ensuring the stability and sustainability of production efficiency.

The first guide rod 702, the pressure plate 705 fixed at the bottom end of the first guide rod 702, and the first buffer spring 704 fixed between the pressure plate 705 and the first buffer spring 704; the second connecting frame 708 pulls the rotating frame 706 and the first connecting frame 707 to push the first moving frame 703 to move synchronously with the second moving frame 805, so that when the pressure plate 705 and the second moving frame 805 move up, the chip resistor is pressed against the inside of the conveying slide 3, so that the detection contact 18 is in close contact with the chip resistor during the process of the reciprocating structure 8 pushing the detection contact 18 for detection.

[0027] like Figure 5 and Figure 6 As shown, as a preferred implementation, based on the above-mentioned method, further, the first connecting frame 707 and the second connecting frame 708 are distributed in parallel, and the pressing plate 705 and the pushing plate 806 are located on the same vertical center line.

[0028] like Figure 7 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the loading structure 20 includes a support 2001 fixed on one side of the top of the cabinet 1, a belt slide 2007 installed on the top of the support 2001, a stepper motor 2006 installed on one side of the top of the belt slide 2007, a third connecting frame 2005 installed on the moving end of the belt slide 2007, a pneumatic telescopic rod 2004 fixed inside one side of the third connecting frame 2005, a pneumatic actuator 2003 installed at the telescopic end of the pneumatic telescopic rod 2004, and a pneumatic suction cup 2002 installed at the bottom end of the pneumatic actuator 2003; the belt slide 2007 is driven to operate by the stepper motor 2006, and then the pneumatic telescopic rod 2004 pushes the pneumatic actuator 2003 to move downward, and the pneumatic suction cup 2002 is used to absorb the chip resistors, and the chip resistors are transported and stacked, which significantly reduces the time and labor of manual operation.

[0029] like Figure 7 As shown, as a preferred embodiment, based on the above method, further, the output shaft end of the stepper motor 2006 is connected to the input shaft end of the belt slide 2007, and the pneumatic suction cups 2002 are evenly distributed at the bottom end of the pneumatic actuator 2003.

[0030] Specifically, when the chip resistor testing and sorting machine is in use: the chip resistor to be tested is poured into the interior of the vibrating feeder tray 2, the vibrating feeder tray 2 is started to vibrate to feed the chip resistor, so that the chip resistor enters the interior of the conveying slide 3 and slides inside the conveying slide 3, the control box 4 detects the surface and position of the chip resistor through the monitoring camera 5, and then the chip resistor is moved to the interior of the fixed frame 6, and the detection contact 18 is driven to rise and fall through the reciprocating structure 8, so that the detection contact 18 is in contact with the contact of the chip resistor, the control box 4 tests the circuit and resistance of the chip resistor through the reciprocating structure 8, and at the same time the fixed structure 7 presses the chip resistor to ensure that the chip resistor is in close contact with the detection contact 18. After the detection is completed, the reciprocating structure 8 is used to drive the detection contact 18 to move up and down, so that the detection contact 18 is in contact with the contact of the chip resistor. The structure 8 drives the detection contact 18 to move downward, and at the same time, the fixed structure 7 releases the chip resistor, so that the subsequent resistor pushes the detected resistor to slide to one side of the pneumatic nozzle 16, and the qualified resistor can continue to move inside the conveying slide 3 and be transported to the subsequent processing equipment. The defective products are blown by the pneumatic nozzle 16, so that they leave the inside of the conveying slide 3 and pass through the waste trough 10 and fall into the collection box 11. The first pneumatic push rod 13 pushes the first mounting frame 14 to move, and when the pneumatic nozzle 16 sprays the defective products, the subsequent chip resistors can be blocked. The good resistors pass through the conveying slide 3 into the storage box 19, and the good resistors are grabbed by the tray loading structure 20 and neatly stacked inside the storage tray 21 for subsequent retrieval and use.

[0031] The cam 802 is driven by the driving motor 801, so that the rotating cam 802 drives the moving rod 804 to move through the connecting rod 803. At the same time, since the positioning sleeve 809 limits the direction and position of the moving rod 804, the cam 802 drives the moving rod 804 to do reciprocating motion. At the same time, the moving rod 804 pushes the second moving frame 805 to move upward, so that the second moving frame 805 pushes the detection contact 18 to move upward through the second buffer spring 807 and the push plate 806. At the same time, the baffle at the top of the push plate 806 can limit the chip resistor to ensure that the detection contact 18 is accurately in contact with the contact of the chip resistor. The second buffer spring 807 can be stretched and deformed to buffer the pressure of the push plate 806 and the detection contact 18 on the chip resistor to prevent the structure of the chip resistor from being damaged by pressure. As the driving motor 801 continues to rotate, the moving rod 804 drives the push plate 806 and the detection contact 18 to fall, so that the chip resistor can move to the right. In the process of the reciprocating structure 8 driving the detection contact 18 to move, the second connecting frame 708 pulls the rotating frame 706 to flip as the second moving frame 805 moves, and at the same time, one end of the rotating frame 706 pushes the first connecting frame 707 to move, so that the first connecting frame 707 pushes the first moving frame 703 to move synchronously with the second moving frame 805, and the moving directions of the two are opposite. At the same time, the sliding rod 701 slides inside the fixed frame 6 to guide the movement of the first moving frame 703. When the second moving frame 805 moves up, the first connecting frame 707 drives the first moving frame 703 to move downward, so that the pressure plate 705 presses the chip resistor inside the conveying slide 3. When the second moving frame 805 moves downward, the first connecting frame 707 drives the first moving frame 703 to move upward, so that the pressure plate 705 releases the chip resistor, and the first buffer spring 704 buffers the pressure of the first moving frame 703 on the pressure plate 705 to prevent the pressure of the pressure plate 705 from being too large, causing the structure of the chip resistor to be damaged by pressure. The pneumatic actuator 2003 is connected to the pneumatic pipeline of the factory to allow the gas to enter the interior of the pneumatic actuator 2003. When the interior of the storage box 19 is filled with chip resistors, the belt slide 2007 is driven by the stepper motor 2006 to operate, so that the belt slide 2007 drives the pneumatic telescopic rod 2004 and the pneumatic actuator 2003 to move to the top of the storage box 19. Then the pneumatic telescopic rod 2004 is extended to push the pneumatic actuator 2003 downward, so that the pneumatic suction cup 2002 contacts the chip resistor, and then the pneumatic actuator 2003 is used. The air pressure inside the pneumatic suction cup 2002 is reduced so that the pneumatic suction cup 2002 adsorbs the chip resistor, the pneumatic telescopic rod 2004 is retracted and the belt slide 2007 is operated to make the pneumatic suction cup 2002 drive the chip resistor to move to the top of the storage tray 21, and the pneumatic telescopic rod 2004 is extended to allow the chip resistor to enter the interior of the storage tray 21, and the pneumatic suction cup 2002 is controlled to release the chip resistor to complete the stacking of the chip resistors, and the pneumatic actuator 2003 controls the supply and discharge of air pressure to allow the pneumatic suction cup 2002 to perform adsorption and release actions.
