[0018] 1. In the present invention, the diodes are tested. For unqualified diodes, the diodes are sucked up by starting the suction cup, the first cylinder is contracted to raise the test frame, and then the rotating rod is rotated to drive the support plate to rotate to the designated area, and the diodes are discarded after the suction cup is closed; for qualified diodes but with incorrect directions, the third motor drives the pressure plate and the telescopic frame to adjust the guide plate by 180 degrees to adjust the direction of the diodes; for qualified diodes with correct directions, the first cylinder is started to contract to raise the test frame, and the qualified diodes enter the next process area with the guide plate.

[0019] The present invention sorts the diodes according to the situation after detecting them, separates unqualified diodes, adjusts the directions of diodes with incorrect directions, and realizes the sorting work before entering the next process, thereby simplifying the screening and sorting process, shortening the time, and improving the efficiency.

[0020] 2. In the present invention, when the material guide plate is flipped, the third cylinder is started to make the first pressure plate and the second pressure plate move downward together, and then the second cylinder is started to contract, driving the T-block to move in the direction close to the material guide plate, driving the suspension block, the first pressure plate and the second pressure plate to move toward the material guide plate together; the pressure rods on the upper and lower end surfaces are squeezed by the pressure plates, and the support rods on the upper and lower end surfaces are extended into the through grooves, and the third cylinder is started to contract to pull the first pressure plate and the second pressure plate to move upward, the rack drives the gear to rotate, and the fixed rod and the material guide plate rotate together until they are flipped 180 degrees. During the flipping process, the support rod realizes the upper and lower limit, so that the diode can change direction smoothly; after the force on the pressure rod is released, the support rod below the diode extends to form a support, and the upper drag rod contracts into the slide groove to form an open state, which is conducive to the next step of processing the diode.

[0021] In the present invention, during the process of arranging and flipping the guide plate 180 degrees, the support rods are extended to limit the diodes to prevent them from falling off. After the flipping is completed, the support rods located below the guide plate remain in a supporting state, and the upper support rods are retracted into the chute to form an open state above the diode, which is conducive to the next process. During the flipping of the diode, the support rods on the upper and lower end surfaces of the guide plate are alternately extended, and no additional control is required, and they are automatically switched, so that stable protection of the diode is achieved, and work efficiency is improved.

In the present invention, the material guide channel is arranged above the star wheel, the top end of the material guide channel is connected to the vibrating screen, and the bottom end of the material guide channel is connected to the inlet above the star wheel; the star wheel is arranged as a hollow structure, and when the hollow shaft rotates, it drives the star wheel to rotate together, and the sleeve and the cam are in a stationary state; the hollow shaft is connected to the negative pressure pipeline to suck air into the inside of the star wheel, and the adsorption hole adsorbs and loads the diodes of the material guide channel; a cam is fixed at the bottom of the sleeve, and the sleeve is in a fixed state, and the pressing plate of the suction stop assembly rotates with the star wheel. During the rotation process, the cam squeezes the pressing plate, so that the pressing plate blocks the adsorption hole, causing the corresponding adsorption hole to lose suction, and the previously adsorbed diode falls under the action of gravity, thereby realizing the fixed-point unloading of the star wheel;

[0023] When the star wheel of the present invention realizes opening and closing to automatically switch the material transportation through negative pressure, the adsorption capacity of the diode is enhanced, so as to avoid the diode not being introduced into the inlet, causing the inlet of the star wheel to be vacant and the transportation resources to be wasted, and to avoid the diode being damaged by shaking and friction during the rotation and transportation, thereby enhancing the stability of the device loading.

[0036] In the present invention, the diodes 15 are distributed to the corresponding guide plates 17 through the conveying assembly, and a support rod 39 that is retracted and extended alternately up and down is provided in the through slot 23 of the guide plate 17. The support rod 39 supports the diodes 15, which is beneficial for the sorting assembly to detect the diodes 15. The sorting assembly can also flip the diodes 15 or transfer the broken diodes.

[0037] like Figure 6 , Figure 7 and Figure 8 As shown in , when the pressure rod 40 on the telescopic frame 24 is squeezed, the telescopic frame 24 compresses the spring 25, the telescopic frame 24 moves in the slide groove 49 toward the through groove 23, and the guide rod 41 at the end of the swing rod 26 abuts and slides in the heart-shaped groove 38;

[0038] When the guide rod 41 is located in the lower end groove of the heart-shaped groove 38, the support rod 39 extends out and is located in the through groove 23;

[0039] When the pressure rod 40 is squeezed, the guide rod 41 moves from the lower end groove of the heart-shaped groove 38 to the upper end groove. When the force on the pressure rod 40 is released, under the pulling force of the spring 25, the guide rod 41 abuts against the bottom wall of the upper end groove of the heart-shaped groove 38 to form a stable state.

[0040] When the pressure rod 40 is released after being pressed again, the guide rod 41 runs from the bottom wall of the upper end groove of the heart-shaped groove 38 to the top wall of the upper end groove and then runs along the adjacent descending groove to the lower end groove.

[0070] The cam 48 is located directly below. When the adsorption hole 45 moves to this position, the adsorption hole 45 is blocked by the pressing sheet 47 and loses its adsorption force. The originally adsorbed diode 15 falls under the action of gravity and falls onto the guide plate 17 .

[0071] During the loading process of the star wheel 11, the adsorption hole 45 is opened to attract the adjacent diode 15 through negative pressure. When reaching the unloading position, the cam 48 is triggered to close the adsorption hole 45 to unload the material, thereby realizing automatic switching between loading and unloading, avoiding the loading port of the star wheel 11 being vacant or unloading failure, and avoiding waste of operating resources.

[0072] Furthermore, the top end of the rotating rod 27 is fixedly connected to the bottom of the supporting plate 16 , and the bottom end of the rotating rod 27 is connected to a servo motor (not shown).

[0073] Figure 4 As shown in FIG. 1 , the servo motor drives the rotating rod 27 and the supporting plate 16 to rotate together, and the damaged diode is taken out of the production line, which is convenient for the processing in the next step.

[0074] Furthermore, the lowest point of the bottom wall of the lower end groove of the heart-shaped groove 38, the lowest point of the top wall of the upper end groove of the heart-shaped groove 38 and the lowest point of the bottom wall of the upper end groove of the heart-shaped groove 38 all deviate from the center line of the heart-shaped groove 38; the lowest point of the top wall of the upper end groove of the heart-shaped groove 38 and the lowest point of the bottom wall of the upper end groove are respectively located on both sides of the center line; the lowest point of the bottom wall of the lower end groove of the heart-shaped groove 38 and the lowest point of the top wall of the upper end groove of the heart-shaped groove 38 are both located on the same side of the center line.

[0075] Figure 8 , which is a top view of the telescopic frame 24 , wherein the heart-shaped groove 38 is set to an eccentric structure, which is beneficial for the guide rod 41 on the swing rod 26 to be in a ring circulation state when sliding in the heart-shaped groove 38 .

[0076] When the guide rod 41 is at the lowest point of the bottom wall of the lower end groove of the heart-shaped groove 38, it is located in a left position. When it is squeezed by external force, the swing rod 26 moves in a left direction and moves along the upper and lower groove channels.

[0077] The guide rod 41 is located at the lowest point of the bottom wall of the upper end groove of the heart-shaped groove 38, and is located in a right position. When squeezed by external force, the rocker arm 26 runs in the right direction until it reaches the right top of the upper end groove. When the external force is released, under the action of the spring 25, the guide rod 41 moves down along the right side groove channel to the lowest point of the bottom wall of the lower end groove.

[0078] Furthermore, a sealing ring (not shown) is arranged between the pressing sheet 46 and the adsorption hole 45. The sealing ring improves the sealing effect and also plays a buffering role when the pressing sheet 46 is squeezed by the cam.

[0079] Working principle:

[0080] 1. The first cylinder 18 drives the detection frame 19 to extend into the through slot 23, and the detection contacts 22 on both sides of the detection frame 19 detect the diode 15. If the diode 15 is detected to be qualified but misaligned in direction, the first cylinder 18 retracts and retracts the detection frame 19, and then the direction of the diode 15 is reversed; if the diode 15 is detected to be unqualified, the diode 15 is sucked up by the suction cup 21 at the bottom of the detection frame 19, and the first cylinder 18 retracts and brings it back to the detection frame 19, and then rotates it to the designated area through the rotating rod 27, and the unqualified diode 15 is discarded; if the diode 15 is qualified and the direction is also correct, the first cylinder 18 retracts and retracts the detection frame 19, and the qualified diode 15 enters the next process area along with the guide plate 17;

[0081] 2. When the guide plate 17 is turned over, the third cylinder 31 is started to make the first pressing plate 32 and the second pressing plate 33 move downward together, and then the second cylinder 28 is started to contract, driving the T-block 29 to move toward the guide plate 17, and driving the suspension block 30, the first pressing plate 32 and the second pressing plate 33 to move toward the guide plate 17 together;

[0082] The first pressing plate 32 and the second pressing plate 33 squeeze the pressing rod 40, and make the rack 37 and the gear 36 in the same radial plane; at this time, the pressing rods 40 on the upper and lower end surfaces are squeezed, and the supporting rods 39 on the upper and lower end surfaces are extended into the through groove 23, and the third cylinder 31 is started to contract to pull the first pressing plate 32 and the second pressing plate 33 to move upward. At the same time, the rack 37 drives the gear 36 to rotate, and the fixed rod 35 and the guide plate 17 rotate together until they are flipped 180 degrees. During the flipping process, the upper and lower supporting rods 39 are limited, so that the diode 15 can change direction smoothly; after the force on the pressing rod 40 is released, the supporting rod 39 below the diode 15 remains in an extended state to form a support, and the upper drag rod 39 shrinks into the slide groove 49 to form an open state, which is conducive to the next step of processing the diode 15.

[0083] The present invention illustrates the technical concept of the present invention through the above embodiments, but the present invention is not limited to the above embodiments, that is, it does not mean that the present invention must rely on the above embodiments to be implemented. Those skilled in the art should understand that the relevant improvements to the present invention fall within the protection scope and disclosure scope of the present invention.
