Description

Technical Field

[0001] The present invention relates to the field of semiconductor device detection devices, and in particular to an automatic picking, replenishing, loading and unloading device for semiconductor devices. Background Art

[0002] As a type of semiconductor device, diodes are composed of P-type and N-type semiconductor materials and have high electrical conductivity and thermal stability. By recycling these discarded 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 has important significance for promoting the development of a circular economy.

[0003] In the process of recycling diodes, it is necessary to use the two test pens of a multimeter to touch the positive and negative poles of the diode respectively to test the diode in order to select the damaged diode and repair it.

[0004] However, since the pins of the diode are relatively soft, the two pins of the diode are easily bent during the recycling process and are difficult to keep in the same straight line, making it difficult for the two test pens of the multimeter to fully contact the two pins of the diode, thereby increasing the difficulty of diode repair.

[0005] To this end, the present invention proposes an automatic picking, replenishing, loading and unloading device for semiconductor devices to solve the above problems. Summary of the Invention

[0006] In order to achieve the above objectives, the technical solution adopted by the present invention is: an automatic picking and filling and loading and unloading device for semiconductor devices, comprising two parts: an automatic picking and filling device and a loading and unloading device;

[0007] Automatic picking and filling device includes:

[0008] A base, wherein a detection assembly is provided on the top of the base, and the detection assembly includes two brackets, and the two brackets are symmetrically fixedly connected to the top of the base;

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

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

[0011] The loading and unloading device includes:

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

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

[0014] A plurality of conveying seats, wherein the plurality of conveying seats are fixedly connected to the conveyor belt in an array, and the two sides of the conveying seats are respectively slidably connected to the side walls of the two track frames, and the top of the conveying seat is provided with a groove for placing the diode body;

[0015] Four L-shaped track grooves, two of which are symmetrically opened on the top right side of the conveying base, and the other two are symmetrically opened on the top right side of the conveying base;

[0016] Four arc-shaped clamping jaws, each of which is slidably connected to an L-shaped track groove at a corresponding position;

[0017] a first pushing assembly, the first pushing assembly being used to push the arc-shaped clamping claw to move the arc-shaped clamping claw along the L-shaped track groove. During the movement of the arc-shaped clamping claw, the arc-shaped clamping claw clamps the two pins of the diode body and pulls the pins of the diode body to straighten them, so that the two pins of the diode body are in a straight line, so that the pins of the diode body contact the two detection walls at the same time, thereby 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 easily bent during the recycling process and are difficult to keep in the same straight line, making it difficult for the two test pens of the multimeter to fully contact the two pins of the diode, thereby increasing the difficulty of diode repair. The present technical solution can solve the above problem. The specific operation is as follows: first, the diode body is placed in the groove of the conveying seat, and then the conveying seat is conveyed to the detection component position by the conveyor belt. In the process of the conveying seat conveying the diode body to the detection component position, the arc-shaped clamping claw is moved along the L-shaped track groove by the first pushing component, so that the arc-shaped clamping claw approaches the pins of the diode body and clamps the pins. Then, the pins of the diode body are pulled by the arc-shaped clamping claw to straighten the pins of the diode body so that the two pins of the diode body are in the same straight line.

[0019] When the pin of the diode body passes through the detection pen, the pin pushes the detection pen, causing the rotating frame to rotate, and the detection pen to rotate to an inclined state. When the pin passes through the bottom of the detection pen, the pin contacts the probe at the bottom of the detection pen, which is conducive to full contact between the detection pen and the pin, so that the circuit is connected, thereby detecting the diode body and selecting the damaged diode body for repair;

[0020] That is to say, the arc-shaped clamp pulls the pin and straightens it. On the one hand, it is helpful for the two pins to contact the two detection pens at the same time, so that the circuit is connected and the test results are obtained. On the other hand, it increases the supporting force, which is helpful for the pin to push the detection pen to flip, so that the pin and the detection pen are fully in contact, reducing the chance of poor contact and then reducing the difficulty of repairing.

[0021] Preferably, the first pushing component includes:

[0022] Four L-shaped connecting plates, one end of each of the four L-shaped connecting plates is fixedly connected to the arc-shaped clamping claws at the corresponding position, and the other end is slidably connected to the L-shaped track groove at the corresponding position;

[0026] Preferably, it also includes:

[0027] Two L-shaped limiting plates, the two L-shaped limiting plates are symmetrically slidably connected to the two ends of the conveying base;

[0028] The second pushing component is used to push the L-shaped limiting plate so that the L-shaped limiting plate is close to the bottom of both ends of the diode body to adjust the diode to the middle position of the conveying seat and limit the diode body.

[0029] Preferably, the second pushing component includes:

[0030] The second guide groove is opened on the outer side wall of the track frame, and the second guide groove has an outer guide groove section, an inner guide groove section, a first oblique groove guide section and a second oblique groove guide section. The first oblique groove guide section is located on the upper side wall of the right end of the track frame, and the second oblique groove guide section is located on the lower side wall of the left end of the track frame. The bottom end of the L-shaped limiting plate is slidably connected to the second guide groove.

[0031] Preferably, it also includes:

[0032] Two arc-shaped clamping plates, the two arc-shaped clamping plates are symmetrically connected to the inner side wall of the groove, and the top ends of the arc-shaped clamping plates extend above the conveying seat;

[0033] The rotary drive assembly is used to drive the arc-shaped clamping plates to rotate so that the two arc-shaped clamping plates clamp the diode body. After the detection is completed, the rotary drive assembly drives the arc-shaped clamping plates to reset so that the bottom end of the arc-shaped clamping plates pushes the diode body, allowing the diode body to quickly disengage from the groove.

[0034] Preferably, the rotary drive assembly comprises:

[0035] Two driving wheels, each of which is coaxially fixed to two sides of the arc-shaped clamping plate. An arc-shaped driving groove is formed on an outer side wall of the driving wheel, and one end of the arc-shaped driving groove is away from the center of the driving wheel, and the other end is close to the center of the driving wheel;

[0037] The third pushing component is used to push the U-shaped pushing frame.

[0038] Preferably, the third pushing component includes:

[0039] Two compression chambers, the two compression chambers corresponding to the positions of the L-shaped limit plates are opened on the outer side wall of the conveying seat;

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] 1. The present invention provides an arc-shaped clamping claw, which pulls the pins of the diode body through the arc-shaped clamping claw to straighten the pins of the diode body, so that the two pins of the diode body are in the same straight line, which is conducive to making the two pins contact with the two detection pens at the same time, thereby connecting the circuit and obtaining the detection result.

[0043] 2. The present invention provides two rotatable detection pens. When the pin of the diode body passes through the detection pen, the pin pushes the detection pen, causing the rotating frame to rotate, so that the detection pen rotates to an inclined state. When the pin passes through the bottom of the detection pen, the pin contacts the probe at the bottom of the detection pen, which is conducive to full contact between the detection pen and the pin, so that the circuit is connected.

[0044] 3. The present invention sets an L-shaped limit plate, and during the movement of the conveying seat, the second pushing component is used to make the L-shaped limit plate move toward the bottom of both ends of the diode body.

On the one hand, it is convenient for the arc-shaped clamp to clamp from the end of the pin, and on the other hand, it stabilizes the diode body when the arc-shaped clamp is pulling the pin.

[0045] 4. The present invention provides an arc-shaped clamping plate. During the movement of the conveying seat, the arc-shaped clamping plate is rotated by the rotary drive component so that the two arc-shaped clamping plates clamp the diode body. After the detection is completed, the rotary drive component drives the arc-shaped clamping plate to reset so that the bottom end of the arc-shaped clamping plate pushes the diode body, allowing the diode body to quickly detach from the groove.

[0061] The base 1 has a detection assembly at the top thereof. The detection assembly includes two brackets 5, which are symmetrically fixedly connected to the top of the base 1. The inner side walls of the tops of the two brackets 5 are rotatably connected to a rotating frame 6. The bottom ends of the rotating frame 6 are symmetrically fixedly connected to detection pens 7. The probes at the bottom ends of the two detection pens 7 extend below the pins of the diode body.

[0062] It is best to have two groups of detection components, the positions of the detection pens 7 in the two groups are interchanged, and the array is set on the top of the base 1;

[0063] Specifically, the two detection pens 7 are rotatably arranged. In the process of the pin of the diode body passing through the detection pen 7, the pin pushes the detection pen 7, causing the rotating frame 6 to rotate, so that the detection pen 7 rotates to an inclined state. In the process of the pin passing from 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. In addition, two sets of detection components can be set to correspond to the positive and negative poles of the diode body respectively to reduce the difficulty of picking and repairing.

[0064] The loading and unloading device includes:

[0065] The conveyor belt 4 is rotatably connected to the inner wall of the base 1;

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

[0067] Several conveying seats 8 are fixedly connected to the conveyor belt 4 in an array. Both sides of the conveying seats 8 are slidably connected to the side walls of the two track frames 16. The top of the conveying seat 8 is provided with a groove 9 for placing the diode body;

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

[0069] Four arc-shaped clamping jaws 11, each of which is slidably connected to the L-shaped track groove 10 at a corresponding position;

[0070] The first pushing component is used to push the arc-shaped clamping jaw 11 so that the arc-shaped clamping jaw 11 moves along the L-shaped track groove 10. During the movement of the arc-shaped clamping jaw 11, the arc-shaped clamping jaw 11 clamps the two pins of the diode body and pulls the pins of the diode body to straighten them, so that the two pins of the diode body are in the same straight line, so that the pins of the diode body contact 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 easily bent during the recycling process and are difficult to keep in the same straight line, making it difficult for the two test pens of the multimeter to fully contact the two pins of the diode, thereby increasing the difficulty of diode repair. The present technical solution can solve the above problem. The specific operation is as follows: 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 conveyor 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 pins of the diode body and clamps the pins. Then, the pins of the diode body are pulled by the arc-shaped clamping claw 11 to straighten the pins of the diode body so that the two pins of the diode body are in the same straight line.

[0072] When the pin of the diode body passes through the detection pen 7, the pin pushes the detection pen 7, causing the rotating frame 6 to rotate, so that 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 full contact between the detection pen 7 and the pin, so that the circuit is connected, thereby detecting the diode body and selecting the damaged diode body for repair;

[0073] That is to say, the arc-shaped clamping claw 11 pulls the pin and straightens the pin. On the one hand, it is beneficial for the two pins to contact 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, it increases the supporting force, which is beneficial for the pin to push the detection pen 7 to flip, thereby facilitating full contact between the pin and the detection pen 7, reducing the chance of poor contact, and then reducing the difficulty of repairing.

[0081] Four driving inclined slots 14, which are respectively provided on the L-shaped connecting plate 13 at corresponding positions;

[0082] The first guide groove 17 is formed on the outer wall of the track frame 16 and includes a traction groove section 1701 and a trapezoidal guide groove section 1702 ;

[0083] Two U-shaped drive frames 15 are symmetrically slidably connected to the outer side of the conveying base 8. The two ends of the U-shaped drive frame 15 are respectively slidably connected to the two drive chute 14 at the corresponding positions. The bottom end of the U-shaped drive frame 15 is slidably connected to the first guide groove 17.

[0084] The detection assembly is located at the trapezoidal guide groove section 1702;

[0085] Specifically, by providing the first guide 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 guide groove 17 until it enters the trapezoidal guide groove section 1702. Driven by the trapezoidal guide groove section 1702, the U-shaped driving frame 15 is moved away from the outer wall of the conveying seat 8. During the process of the U-shaped driving frame 15 moving away from the outer 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 it.

[0089] Specifically, by setting an L-shaped limit plate 19, during the movement of the conveying seat 8, the second pushing component is used to make the L-shaped limit plate 19 move toward the bottom of both ends of the diode body. The L-shaped limit plate 19 pushes the excess 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 stabilizes the diode body during the process of the arc-shaped clamping jaw 11 pulling the pin.

The bottom end of the L-shaped limiting plate 19 is slidably connected to the second guide groove 18.

[0092] Specifically, by setting the second guide groove 18, during the movement of the conveying seat 8, the L-shaped limit plate 19 moves along the second guide groove 18, and under the drive of the first inclined groove guide section 1803, the L-shaped limit plate 19 enters the inner guide groove section 1802 from the outer guide groove section 1801, thereby moving the L-shaped limit plate 19 to the bottom of both ends of the diode body. After the detection is completed, under the drive of the second inclined groove guide section 1804, the L-shaped limit plate 19 is moved away from the side wall of the conveying seat 8, reducing the interference space to facilitate the placement of the diode body.

[0096] Specifically, by setting an arc-shaped clamping plate 20, during the movement of the conveying seat 8, the arc-shaped clamping plate 20 is rotated by the rotating drive component, so that the two arc-shaped clamping plates 20 clamp the diode body. After the detection is completed, the rotating drive component 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, so that the diode body quickly disengages from the groove 9.

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 detaches from the groove 9.

[0107] First, the diode body is placed into the groove 9 of the conveying seat 8, and then the conveying seat 8 is conveyed to the detection assembly position by the conveyor belt 4. During the process of the conveying seat 8 conveying the diode body to the detection assembly position, the arc-shaped clamping claw 11 is moved along the L-shaped track groove 10 by the first pushing assembly, so that the arc-shaped clamping claw 11 approaches the pins of the diode body and clamps the pins. Then, the arc-shaped clamping claw 11 pulls the pins of the diode body to straighten the pins 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, causing the rotating frame 6 to rotate, so that 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 full contact between the detection pen 7 and 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 the pin. On the one hand, it is beneficial for the two pins to contact 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, it increases the supporting force, which is beneficial for the pin to push the detection pen 7 to flip, thereby facilitating full contact between the pin and the detection pen 7, reducing the chance of poor contact, and then reducing the difficulty of repairing.
