[0001] The present invention relates to the field of semiconductor device detection devices, and particularly to a semiconductor device automatic picking, mending, loading and unloading device. Background Art

[0002] As a type of semiconductor device, a diode is composed of P-type and N-type semiconductor materials, has high conductivity and thermal stability. By recycling these waste diodes, resources can be effectively utilized and the consumption of natural resources can be reduced. This not only helps to reduce production costs and resource consumption, but also is of great significance for promoting the development of circular economy.

[0003] In the process of recycling diodes, two test pens of a multimeter need to be respectively contacted with the positive and negative electrodes of the diode to test the diode, so as to pick out the damaged diodes and mend them.

[0004] However, since the pins of the diode are relatively soft, the two pins of the diode are prone to bending during the recycling process and it is difficult to keep them on the same straight line, making it difficult for the two test pens of the multimeter to fully contact the two pins of the diode, thus increasing the difficulty of picking and mending the diode.

[0005] Therefore, the present invention proposes a semiconductor device automatic picking, mending, loading and unloading device to solve the above problems. Summary of the Invention

[0009] A rotating frame, the two ends of which are respectively rotatably connected to the side walls of the two brackets;

[0010] Two test pens, the two test pens are symmetrically and fixedly connected to the rotating frame, and the bottom probes of the two test pens extend below the pins of the diode body.

[0011] The loading and unloading device includes:

[0012] A conveyor belt, which is rotatably connected to the inner side wall of the base;

[0013] Two track frames, the two track frames are symmetrically and fixedly connected to the base;

[0014] Several conveying seats, several of the conveying seats are fixedly connected to the conveyor belt in an array, both sides of the conveying seats are slidably connected to the side walls of two track frames respectively, and a groove for placing the diode body is formed at the top of the conveying seat;

[0015] Four L-shaped track grooves, two of the L-shaped track grooves are symmetrically formed at the top end of the right side of the conveying seat, and the other two L-shaped track grooves are symmetrically formed at the top end of the right side of the conveying seat;

[0016] Four arc-shaped clamping jaws, the four arc-shaped clamping jaws are respectively slidably connected in the L-shaped track grooves at corresponding positions;

[0017] A first pushing assembly, the first pushing assembly is used to push the arc-shaped clamping jaws to move the arc-shaped clamping jaws along the L-shaped track grooves. During the movement of the arc-shaped clamping jaws, the two pins of the diode body are clamped by the arc-shaped clamping jaws, and the pins of the diode body are pulled to be straightened, so that the two pins of the diode body are on the same straight line, so that the two pins of the diode body are in contact with two detection walls at the same time, ensuring the connectivity of the circuit;

[0018] Specifically, in the prior art, since the pins of the diode are relatively soft, the two pins of the diode are prone to bending during the recycling process and it is difficult to keep them on the same straight line, making it difficult for the two test pens of the multimeter to make full contact with the two pins of the diode, thus increasing the difficulty of selecting and mending the diode. The technical solution of the present invention can solve the above problems. The specific operation is as follows: first, place the diode body into the groove of the conveying seat, and then, through the conveyor belt, convey the conveying seat to the position of the detection assembly. During the process of conveying the diode body to the position of the detection assembly by the conveying seat, through the first pushing assembly, the arc-shaped clamping jaws move along the L-shaped track grooves, so that the arc-shaped clamping jaws approach the pins of the diode body and clamp the pins, and then the pins of the diode body are pulled by the arc-shaped clamping jaws to straighten the pins of the diode body, so that the two pins of the diode body are on the same straight line;

[0019] During the process that the pins of the diode body pass through the test pen, the pins push the test pen, causing the rotating frame to rotate, so that the test pen rotates to an inclined state. During the process that the pins pass through the bottom of the test pen, the pins contact the bottom probe of the test pen, which is beneficial to making the test pen make full contact with the pins, making the circuit connected, thereby detecting the diode body and selecting the damaged diode body for repair;

[0020] That is to say, the arc-shaped clamping jaws pull the pins to straighten the pins.

The bottom ends of the rotating frame 6 are symmetrically and fixedly connected with detection pens 7. The bottom probes of the two detection pens 7 extend below the pins of the diode body;

[0062] Preferably, there are two sets of the detection components. The positions of the detection pens 7 in the two sets are swapped with each other and are arranged in an array on the top of the base 1;

[0063] Specifically, the two detection pens 7 are rotatably arranged. During the process that the pins of the diode body pass through the detection pens 7, the pins push the detection pens 7, causing the rotating frame 6 to rotate, so that the detection pens 7 rotate to an inclined state. During the process that the pins pass through the bottom of the detection pens 7, the pins contact the bottom probes of the detection pens 7, which is beneficial to make the detection pens 7 fully contact with the pins, so that the circuit is connected, thereby detecting the diode body, picking out the damaged diode bodies for repair, and two sets of detection components can be set to respectively correspond to the positive and negative poles of the diode body to reduce the difficulty of picking and mending.

[0064] The loading and unloading device includes:

[0065] Conveyor belt 4, and the conveyor belt 4 is rotatably connected to the inner side wall of the base 1;

[0066] Two track frames 16, and the two track frames 16 are symmetrically and fixedly connected to the base 1;

[0067] Several conveying seats 8, and the several conveying seats 8 are arrayed and fixedly connected to the conveyor belt 4. The two sides of the conveying seat 8 are respectively slidably connected to the side walls of the two track frames 16. A groove 9 for placing the diode body is opened at the top of the conveying seat 8;

[0068] Four L-shaped track grooves 10, where two L-shaped track grooves 10 are symmetrically opened at the right top end of the conveying seat 8, and the other two L-shaped track grooves 10 are symmetrically opened at the right top end of the conveying seat 8;

[0069] Four arc-shaped clamping jaws 11, and the four arc-shaped clamping jaws 11 are respectively slidably connected in the L-shaped track grooves 10 at corresponding positions;

[0070] A first pushing assembly, which is used to push the arc-shaped clamping jaws 11 so that the arc-shaped clamping jaws 11 move along the L-shaped track grooves 10. During the movement of the arc-shaped clamping jaws 11, the arc-shaped clamping jaws 11 clamp the two pins of the diode body and pull the pins of the diode body to be straightened, so that the two pins of the diode body are on the same straight line, so that the two pins of the diode body are in contact with the two detection walls at the same time, ensuring the connectivity of the circuit;

[0071] Specifically, in the prior art, since the pins of the diode are relatively soft, the two pins of the diode are prone to bending during the recycling process and it is difficult to keep them on the same straight line, making it difficult for the two test pens of the multimeter to make full contact with the two pins of the diode, thus increasing the difficulty of selecting and mending the diode. This technical solution can solve the above problems. The specific operation is as follows. First, place the diode body into the groove 9 of the conveying seat 8, and then through the conveyor belt 4, convey the conveying seat 8 to the position of the detection assembly. During the process of conveying the diode body to the position of the detection assembly by the conveying seat 8, through the first pushing assembly, the arc-shaped clamping jaws 11 move along the L-shaped track grooves 10, so that the arc-shaped clamping jaws 11 approach the pins of the diode body and clamp the pins, and then pull the pins of the diode body through the arc-shaped clamping jaws 11 to straighten the pins of the diode body so that the two pins of the diode body are on the same straight line;

[0072] During the process that the pins of the diode body pass through the test pen 7, the pins push the test pen 7, causing the rotating frame 6 to rotate, so that the test pen 7 rotates to an inclined state. During the process that the pins pass through the bottom of the test pen 7, the pins contact the bottom probe of the test pen 7, which is beneficial to making the test pen 7 make full contact with the pins, enabling the circuit to be connected, thereby detecting the diode body and selecting the damaged diode body for repair;

[0073] That is, the arc-shaped gripper 11 pulls the pin to straighten it. On the one hand, it is beneficial for the two pins to come into contact with the two detection pens 7 simultaneously, thus connecting the circuit and obtaining the detection result. On the other hand, it improves the supporting force, which is beneficial for the pin to push the detection pen 7 to flip, so as to facilitate the full contact between the pin and the detection pen 7, reduce the probability of poor contact, and then reduce the difficulty of pick and repair.

[0074] As a further implementation of the present invention, it further includes:

[0075] An arc-shaped rubber block 12, which is fixedly connected to the inner side wall of the arc-shaped gripper 11;

[0076] Specifically, by setting the arc-shaped rubber block 12, on the one hand, it ensures the clamping force of the arc-shaped gripper 11 on the pin, which is beneficial for the arc-shaped gripper 11 to fully pull and straighten the pins of the diode body. On the other hand, it reduces the wear of the pins during the pulling process.

[0077] In the specific implementation process, it further includes: two driving rollers 3, which are symmetrically and rotatably connected to the inner side wall of the base 1, and the conveyor belt 4 is drivingly connected to the surfaces of the two driving rollers 3;

[0082] A first guiding groove 17, which is opened on the outer side wall of the track frame 16, and the first guiding groove 17 has a traction groove section 1701 and a trapezoidal guiding groove section 1702;

[0083] Two U-shaped driving frames 15, which are symmetrically and slidably connected to the outer side pen of the conveying seat 8, and both ends of the U-shaped driving frame 15 are respectively slidably connected to the corresponding two driving inclined grooves 14, and the bottom end of the U-shaped driving frame 15 is slidably connected to the first guiding groove 17;

[0084] Wherein the detection component is located at the trapezoidal guiding groove section 1702;

[0085] Specifically, by setting the first guiding groove 17 and the U-shaped driving frame 15, during the movement of the conveying seat 8, the U-shaped driving frame 15 moves along the first guiding groove 17 until it enters the trapezoidal guiding groove section 1702. Driven by the trapezoidal guiding groove section 1702, the U-shaped driving frame 15 moves away from the outer side wall of the conveying seat 8. During the process of the U-shaped driving frame 15 moving away from the outer side wall of the conveying seat 8, driven by the driving inclined groove 14, the arc-shaped clamping jaw 11 first approaches the pin, and then pulls the pin to straighten the pin.

[0086] As a further embodiment of the present invention, it further includes:

[0087] Two L-shaped limiting plates 19, and the two L-shaped limiting plates 19 are symmetrically and slidably connected to both ends of the conveying seat 8;

[0089] Specifically, by setting the L-shaped limiting plate 19, during the movement of the conveying seat 8 through the second pushing component, the L-shaped limiting plate 19 moves towards the bottom of both ends of the diode body. The L-shaped limiting plate 19 pushes the redundant part of the diode body, so that the diode body moves to the middle position of the conveying seat 8 and limits the diode body. On the one hand, it is convenient for the arc-shaped clamping jaw 11 to clamp from the end of the pin, and on the other hand, it makes the diode body stable during the process of the arc-shaped clamping jaw 11 pulling the pin.

[0090] As an optional embodiment of the second pushing component, the second pushing component includes:

The second guiding groove 18 has an outer guiding groove section 1801, an inner guiding groove section 1802, a first inclined groove guiding section 1803 and a second inclined groove guiding section 1804. The first inclined groove guiding section 1803 is located on the upper side wall of the right end of the track frame 16, and the second inclined groove guiding section 1804 is located on the lower side wall of the left end of the track frame 16. The bottom end of the L-shaped limiting plate 19 is slidably connected in the second guiding groove 18;

[0092] Specifically, by setting the second guiding groove 18, during the movement of the conveying seat 8, the L-shaped limiting plate 19 moves along the second guiding groove 18. Driven by the first inclined groove guiding section 1803, the L-shaped limiting plate 19 enters the inner guiding groove section 1802 from the outer guiding groove section 1801, so that the L-shaped limiting plate 19 moves towards the bottom of both ends of the diode body. After the detection is completed, driven by the second inclined groove guiding section 1804, the L-shaped limiting plate 19 moves away from the side wall of the conveying seat 8 to reduce the interference space for facilitating the placement of the diode body.

[0095] A rotation driving assembly for driving the arc-shaped clamping plate 20 to rotate;

[0096] Specifically, by providing the arc-shaped clamping plate 20, during the movement of the conveying seat 8, the rotation driving assembly is used to make the arc-shaped clamping plate 20 rotate, so that the two arc-shaped clamping plates 20 clamp the diode body. After the detection is completed, the rotation driving assembly drives the arc-shaped clamping plate 20 to reset, so that the bottom end of the arc-shaped clamping plate 20 pushes the diode body, and the diode body quickly disengages from the groove 9.

[0099] A U-shaped pushing frame 23, which is slidably connected in the conveying seat 8, and one end of the U-shaped pushing frame 23 is slidably connected in the arc-shaped driving groove 22;

[0100] As an optional embodiment of the third pushing assembly, the third pushing assembly is used to push the U-shaped pushing frame 23;

[0101] Specifically, by providing the U-shaped pushing frame 23 and the third pushing assembly, during the movement of the conveying seat 8, the third pushing assembly is used to push the U-shaped pushing frame 23, so that the end of the U-shaped pushing frame 23 approaches the center of the driving wheel 21 along the direction. Driven by the arc-shaped driving groove 22, the driving wheel 21 rotates, so that the arc-shaped clamping plate 20 flips to clamp the diode body. After the detection is completed, the third pushing assembly is used to push the U-shaped pushing frame 23 to reset, so that the arc-shaped clamping plate 20 flips and resets, and the bottom end of the arc-shaped clamping plate 20 pushes the diode body, and the diode body quickly disengages from the groove 9.

[0102] The third pushing assembly includes:

[0103] Two compression chambers 24, which are opened on the outer side wall of the conveying seat 8 corresponding to the positions of the L-shaped limiting plates 19;

[0105] Specifically, by setting a compression chamber 24, a folded air chamber 25 and a piston rod 26, in the process of the L-shaped limit plate 19 approaching the side wall of the conveying seat 8, the gas in the compression chamber 24 is compressed, so that the pressure in the folded air chamber 25 increases, and under the action of the pressure, the end of the U-shaped pushing frame 23 approaches the center direction of the driving wheel 21, and under the drive of the arc-shaped driving groove 22, the driving wheel 21 rotates, so that the arc-shaped clamping plate 20 flips over to clamp the diode body. After the detection is completed, the L-shaped limit plate 19 is away from the outer wall of the conveying seat 8. Under the action of pressure, the U-shaped pushing frame 23 is reset, and the arc-shaped clamping plate 20 is flipped and reset, so that the bottom end of the arc-shaped clamping plate 20 pushes the diode body, so that the diode body quickly disengages from the groove 9.

[0106] Working principle of the present invention:

[0107] First, the diode body is placed in the groove 9 of the conveying seat 8, and then the conveying seat 8 is conveyed to the detection component position by the conveying belt 4. In the process of the conveying seat 8 conveying the diode body to the detection component position, the arc-shaped clamping claw 11 is moved along the L-shaped track groove 10 by the first pushing component, so that the arc-shaped clamping claw 11 is close to the pin of the diode body and clamps the pin, and then the pin of the diode body is pulled by the arc-shaped clamping claw 11 to straighten the pin of the diode body so that the two pins of the diode body are in the same straight line;

[0108] When the pin of the diode body passes through the detection pen 7, the pin pushes the detection pen 7, so that the rotating frame 6 rotates, and the detection pen 7 rotates to an inclined state. When the pin passes through the bottom of the detection pen 7, the pin contacts the probe at the bottom of the detection pen 7, which is conducive to making the detection pen 7 fully contact with the pin, so that the circuit is connected, thereby detecting the diode body and selecting the damaged diode body for repair;

[0109] That is to say, the arc-shaped clamping claw 11 pulls the pin and straightens it. On the one hand, it is helpful to make the two pins contact with the two detection pens 7 at the same time, so that the circuit is connected and the detection result is obtained. On the other hand, the supporting force is improved, which is helpful for the pin to push the detection pen 7 to flip, so as to make the pin and the detection pen 7 fully contact, reduce the probability of poor contact, and then reduce the difficulty of repairing.

[0110] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, various changes and improvements will occur to the present invention, and all these changes and improvements fall within the scope of the present invention claimed.
