[0001] This invention relates to the field of semiconductor device handling and pressing technology, and more specifically, to a handling and pressing device for semiconductor devices and its operating method. Background Technology

[0002] Semiconductor devices are electronic devices whose conductivity lies between that of a good conductor and an insulator. They utilize the special electrical properties of semiconductor materials to perform specific functions. They can be used to generate, control, receive, transform, and amplify signals and perform energy conversion. The semiconductor materials of semiconductor devices are silicon, germanium, or gallium arsenide, and they can be used as rectifiers, oscillators, light emitters, amplifiers, photometers, and other equipment.

[0003] With the widespread use and rapid development of electronic products, the demand for electronic connectors inside these products is increasing. However, traditional automatic pin insertion machines directly package the products after a series of processes, including feeding, inserting, and insertion, without secondary pressing and testing.

[0014] A method for handling and pressing semiconductor devices, using the injection molding equipment described above, comprises the following steps:

[0015] S1. The motor starts, and the output end of the motor drives the conveyor plate to move forward to the next station. The suction nozzles on the conveyor plate that are close to the previous process will pick up the PCS products that have been pre-processed in front and put them into the ready-to-move state.

[0016] S2. Next, the output end of the motor drives the conveyor plate to start a semi-circular motion. The suction nozzle close to the previous process places the initially processed PCS product on the carrier close to the previous process, waiting for the first deep pressing.

[0017] S3. At the same time, the upper pressure cylinder is activated and pushes the moving plate forward. The spring plate on the moving plate pushes the movable plate forward by squeezing the spring. Then the pressure bar on the movable plate also moves towards the PIN of the PCS product. When the spring is squeezed to a certain depth, the arc surface on the pressure bar begins to fit with the arc groove on the spring plate. Then the arc groove squeezes the arc surface, causing the arc surface to move upward, thereby causing the pressure bar to tilt, so that the pressure head presses down on the PIN of the PCS product.

[0018] S4. Subsequently, the electric cylinder is started, and the output end of the electric cylinder drives the telescopic plate on the slide to move, thereby driving the PIN push rod on the telescopic plate to push the PIN into the PCS product and press the PIN into place.

[0019] S5. After the first deep pressing is completed, the transport plate moves in a circular motion again. The nozzle closer to the previous process places the pre-processed PCS product on the carrier closer to the previous process again, waiting for the first deep pressing. Meanwhile, the nozzle in the middle closer to the previous process places the PCS product that has completed the first deep pressing on the carrier away from the previous process, waiting for the second deep pressing.

[0020] S6. Simultaneously, the upper pressure cylinder is activated, pushing the moving plate forward. The spring plate on the moving plate, by compressing the spring, pushes the movable plate forward, causing the pressure bar on the movable plate to move towards the PIN of the PCS product. When the spring is compressed to a certain depth, the arc-shaped surface on the pressure bar begins to fit with the arc-shaped groove on the spring plate. Then, the arc-shaped groove compresses the arc-shaped surface, causing the arc-shaped surface to move upward, thereby causing the pressure bar to tilt, so that the pressure head presses down on the PIN of the PCS product. Subsequently, the electric cylinder is activated, and the output end of the electric cylinder drives the telescopic plate on the slide to move, thereby driving the PIN push rod on the telescopic plate to advance towards the PCS product, pressing the PIN into place.

[0021] S7. After the second deep pressing is completed, the transport plate moves in a circular motion again. The suction nozzle near the previous process places the pre-processed PCS product on the carrier near the previous process again, waiting for the first deep pressing. The suction nozzle in the middle near the previous process places the PCS product that has completed the first deep pressing on the carrier away from the previous process, waiting for the second deep pressing. The suction nozzle in the middle near the suction station places the PCS product that has completed the second deep pressing on the suction station, waiting for the suction nozzle on the transport plate near the subsequent process to be sucked up.

[0022] S8. At the same time, the drive motor starts, the turntable station rotates, and the camera inspects the PCS products passing through the camera port. When the inspected product is qualified, the suction nozzle on the transport plate near the subsequent process will pick up the qualified product at the suction station and transfer it to the subsequent station. When the camera detects that the product is unqualified, the suction nozzle on the transport plate near the subsequent process will grab the unqualified product and release it when it is transported to the top of the storage box, thereby collecting the defective product.

[0023] The advantages of this invention are:

[0024] 1. By cooperating with the support columns, support plates, uprights and triangular plates, the height of the handling components and pressing components can be adjusted so that the handling components and pressing components are at the same height as the previous station, thereby facilitating the handling and pressing of the handling components and pressing components.

[0025] 2. The upper pressure cylinder is activated to hold the PCS product in place, thus preventing the PCS product from tilting upwards. The electric cylinder then moves to push the PIN pusher into the carrier, so that the PIN pusher presses the PCS product into place, avoiding the problem of product defects caused by insufficient PIN insertion depth. Moreover, through the cooperation of the upper pressure cylinder, electric cylinder, carrier, and PIN pusher, the PCS product is pressed in a second depth, thereby improving the production quality of PCS products and saving costs.

[0026] 3. The symmetrically arranged electric cylinders allow each product to be used independently, thus ensuring the stability of the pressing force and depth, avoiding the problem of product defects caused by insufficient insertion depth, thereby improving the quality of PCS products and saving costs.

[0027] 4. The pressure head is made of soft material, which prevents scratches on the surface of the PCS product. The design of the arc surface on the pressure bar and the arc groove on the spring plate makes the arc surface be squeezed upward by the arc groove when the spring plate presses the spring forward. This achieves the purpose of pressing the PCS product with the pressure head on the pressure bar, thereby improving the accuracy of the PIN push rod on the electric cylinder, and further improving the quality and efficiency of production.

[0041] Example 1

[0042] Please see Figure 1-9 The present invention provides the following technical solutions:

[0043] A handling and pressing device for semiconductor devices includes a support assembly 100, a handling assembly 200, and a pressing assembly 300. The support assembly 100 places the handling assembly 200 and the pressing assembly 300 at the same height, thereby facilitating the handling assembly 200 to handle PCS products and the pressing assembly 300 to press them in. The pressing assembly 300 performs a secondary deep pressing of the pre-processed PCS products, thereby avoiding the problem of product defects due to insufficient insertion depth, thus improving the quality of PCS products and saving costs.

[0044] Specifically, the support assembly 100 includes a support column 101, support plates 102 symmetrically arranged at both ends of the support column 101, a vertical plate 103 arranged at one end of the support plate 102, and a triangular plate 104 arranged on the side wall of the vertical plate 103 away from the support plate 102. The support column 101, support plate 102, vertical plate 103 and triangular plate 104 cooperate with each other to adjust the height of the transport assembly 200 and the pressing assembly 300, so that the transport assembly 200 and the pressing assembly 300 maintain the same height as the previous station, thereby facilitating the transport and pressing of the transport assembly 200 and the pressing assembly 300.

[0045] Specifically, the conveying assembly 200 is mounted on the triangular plate 104 and includes a motor 201, a horizontal plate 202 mounted on the side wall of the motor 201, uprights 203 symmetrically mounted at both ends of the horizontal plate 202, and a conveying component 204 mounted on the side of the horizontal plate 202 away from the motor 201.

[0046] Specifically, the pressing component 300 is disposed on the top of the support plate 102 and the triangular plate 104, including an electric cylinder 301, a PIN push rod 302 disposed at one end of the electric cylinder 301, a carrier 303 disposed at the end of the PIN push rod 302 away from the electric cylinder 301, and an upper pressing cylinder 304 disposed on the side of the carrier 303 away from the PIN push rod 302.

[0047] The upper cylinder 304 is activated to press the PCS product in place, thereby preventing the PCS product from tilting upwards. The electric cylinder 301 then moves to push the PIN push rod 302 onto the carrier 303, so that the PIN push rod 302 presses the PCS product into place, avoiding the problem of product defects caused by insufficient PIN insertion depth. Moreover, through the cooperation of the upper cylinder 304, electric cylinder 301, carrier 303 and PIN push rod 302, the PCS product is pressed in a second depth, thereby improving the production quality of the PCS product and saving costs.

[0048] Furthermore, the horizontal plate 202 has symmetrical through holes 202a on its side wall along the length direction. The transport component 204 can be connected to the output end of the motor 201 through the through holes 202a. The transport component 204 and the motor 201 are connected through the through holes 202a, so that the motor 201 provides a power source for the transport component 204, thereby achieving the purpose of transporting the transport component 204.

[0049] Furthermore, the transport component 204 includes a transport plate 204a, a fixture 204b disposed on the side wall of the transport plate 204a, and a suction nozzle 204c that is inserted into and cooperates with the fixture 204b; wherein, the transport plate 204a has symmetrically provided mounting holes 204a-1 on the side wall along the length direction, and a rotating plate 204d is symmetrically provided between the transport plate 204a and the horizontal plate 202, one end of the rotating plate 204d is connected to the output end of the motor 201, and the other end is connected to the transport plate 204a through the mounting hole 204a-1.

[0050] The motor 201 rotates the rotating plate 204d, thereby driving the suction nozzle 204c on the conveying plate 204a to transport and pick up the products. This avoids the probability of damage to the PCS products caused by manual contact, improves the production quality of the PCS products, and the suction nozzle 204c is made of PEEK material, which achieves the purpose of preventing scratches on the PCS products.

[0051] Specifically, the retainers 204b are distributed along the length of the transport plate 204a, and multiple sets are provided. Among them, the retainers 204b have a cutout 204b-1 on the side wall away from the transport plate 204a. The top and bottom of the cutout 204b-1 are provided with fixing holes 204b-2. The suction nozzle 204c can be inserted into the fixing hole 204b-2. By setting multiple sets of retainers 204b and suction nozzles 204c, 4 pieces of products can be picked up at one time, and the products can be transported, picked up and pressed in at the same time, thereby improving work efficiency and saving time.

[0052] Furthermore, the electric cylinders 301 are symmetrically distributed in the radial N direction on the top of the support plate 102. The output shaft of the electric cylinders 301 is fitted with a slide rail 301a, and a slide table 301b is provided on the slide rail 301a. The slide rail 301a and the slide table 301b are slidably connected. The slide table 301b is H-shaped. A telescopic plate 301c is provided on the side of the slide table 301b away from the slide rail 301a. The end of the PIN needle push rod 302 away from the carrier 303 is connected to one end of the telescopic plate 301c.

[0053] The symmetrically arranged electric cylinders 301 allow each product to be used independently, thus ensuring the stability of the pressing force and depth, avoiding the problem of product defects caused by insufficient insertion depth, thereby improving the quality of PCS products and saving costs; while the arrangement of slide rails 301a and slide tables 301b ensures that the PIN push rod 302 has sufficient length to push the PCS products in.

[0054] Furthermore, the carrier 303 is symmetrically distributed at the top end along the length of the upright plate 103. The top of the carrier 303 is provided with a docking groove 303a in the radial N direction, and the docking groove 303a is provided with limiting bosses 303b symmetrically arranged in the axial M direction. The end of the PIN push rod 302 away from the telescopic plate 301c can be inserted into the docking groove 303a, and multiple sets of limiting bosses 303b are provided.

[0055] The size of the docking groove 303a can fit the PCS product, thereby improving the stability of the PCS product placement. In addition, multiple sets of limiting bosses 303b are set to place each PIN pin in the PCS product separately, avoiding wear and bending of the PIN pin, thereby improving the production quality of the product, increasing work efficiency, and saving costs.

[0056] Furthermore, the pressing cylinders 304 are symmetrically distributed in the radial N direction on the top of the triangular plate 104. One end of the pressing cylinder 304 is provided with a first guide rail 304a, a first guide platform 304b is provided on the first guide rail 304a, and a movable plate 304c is provided on the top of the first guide platform 304b. The first guide rail 304a and the first guide platform 304b are slidably connected, and the output end of the pressing cylinder 304 is connected to one end of the movable plate 304c. The symmetrical arrangement of the pressing cylinders 304 allows each product to be used independently, thereby ensuring the stability of the pressing force on the PCS product, achieving the purpose of preventing the PCS product from tilting upwards, thus improving the quality of the PCS product and saving costs.

[0057] Specifically, a second guide rail 304d is provided on the top of the movable plate 304c, a second guide platform 304e is provided on the second guide rail 304d, and a movable plate 304f is provided on the second guide platform 304e. The second guide rail 304d and the second guide platform 304e are slidably connected. A spring plate 304g is provided at one end of the second guide rail 304d. The spring plate 304g is L-shaped. A spring 304h is provided on one side of the spring plate 304g along its length. The end of the spring 304h away from the spring plate 304g is connected to the side wall of the movable plate 304f.

[0058] The upper pressure cylinder 304 pushes the moving plate 304c, which in turn drives the spring plate 304g to push the movable plate 304f through the spring 304h, thereby bringing the movable plate 304f closer to the carrier 303 and achieving the purpose of displacement.

[0059] Furthermore, the top of the movable plate 304f is symmetrically provided with ear plates 304f-1 in the radial N direction, and a pressure strip 304i is provided in the middle of the ear plate 304f-1. A pressure head 304j is provided at one end of the pressure strip 304i. The pressure strip 304i is distributed in the radial N direction on the top of the movable plate 304f. The pressure strip 304i is bolted to the ear plate 304f-1. An arc-shaped surface 304i-1 is provided at the end of the pressure strip 304i away from the pressure head 304j. An arc-shaped groove 304g-1 is provided on the side wall of the spring plate 304g near the pressure strip 304i. The arc-shaped surface 304i-1 can slide in the arc-shaped groove 304g-1. The pressure head 304j is distributed at the end of the mating groove 303a away from the PIN needle push rod 302. The suction nozzle 204c is distributed between the PIN needle push rod 302 and the pressure head 304j.

[0060] The pressure head 304j is made of soft material to prevent scratches on the surface of the PCS product. The design of the arc surface 304i-1 on the pressure bar 304i and the arc groove 304g-1 on the spring plate 304g ensures that when the spring plate 304g presses the spring 304h forward, the arc surface 304i-1 is squeezed upward by the arc groove 304g-1. This achieves the purpose of pressing the pressure head 304j on the pressure bar 304i to hold the PCS product in place, thereby improving the accuracy of the PIN push rod 302 on the electric cylinder 301 and further improving the quality and efficiency of production.

[0061] Furthermore, a detection module 400 is also provided on one side of the support plate 102; the detection module 400 includes a camera 401, a detection frame 402 disposed on one side of the camera 401, a drive motor 403 disposed in the detection frame 402, a turntable station 404 disposed on the top of the detection frame 402, and a detection carrier 405 disposed on the turntable station 404; wherein, the turntable station 404 is cross-shaped, the detection carrier 405 is distributed on the cross-shaped station of the turntable station 404 near the camera 401, and a suction station 406 is disposed on the cross-shaped station away from the camera 401, and a storage box 407 is disposed between the suction station 406 and the detection carrier 405.

[0062] The camera 401 detects the insertion depth and the spacing of the pins. The camera 401 is 1200W and backlit. After the PCS products are picked up and placed on the testing carrier 405, the turntable station 404 rotates to the position of the camera 401 to start the testing. When the product is qualified, the suction nozzle 204c on the transfer plate 204a, which is close to the subsequent process, will pick up the qualified product on the picking station 406 and transfer it to the subsequent station. When the camera 401 detects a product as unqualified, the suction nozzle 204c on the transfer plate 204a, which is close to the subsequent process, will pick up the unqualified product and release it when it is transported to the top of the storage box 407, thereby collecting the defective products.

[0063] Example 2

[0064] Please see Figure 1-9 The operation of the above-mentioned device is explained as follows:

[0065] Step 1: Motor 201 starts, and the output end of motor 201 drives the conveyor plate 204a to move forward to the next station. The suction nozzle 204c on the conveyor plate 204a, which is close to the previous process, will pick up the PCS products that have been initially processed and put them into the ready-to-move state.

[0066] Step 2: Next, the output end of motor 201 drives the conveyor plate 204a to start a semi-circular motion. The suction nozzle 204c, which is close to the previous process, places the initially processed PCS product on the carrier close to the previous process, waiting for the first deep pressing.

[0067] Step 3: Simultaneously, the upper pressure cylinder is activated and pushes the moving plate 304c forward. The spring plate 304g on the moving plate 304c pushes the movable plate 304f forward by squeezing the spring. Consequently, the pressure bar 304i on the movable plate 304f also moves toward the PIN of the PCS product. When the spring is squeezed to a certain depth, the arc surface 304i-1 on the pressure bar 304i begins to fit with the arc groove 304g-1 on the spring plate 304g. Then, the arc groove 304g-1 squeezes the arc surface 304i-1, causing the arc surface 304i-1 to move upward, thereby causing the pressure bar 304i to tilt, so that the pressure head 304j presses down on the PIN of the PCS product.

[0068] Step 4: Subsequently, the electric cylinder 301 is started. The output end of the electric cylinder 301 drives the telescopic plate 301c on the slide 301b to move, thereby driving the PIN push rod 302 on the telescopic plate 301c to push the PIN into place.

[0069] Step 5: After the first deep pressing is completed, the transport plate 204a makes a circular motion again. The suction nozzle 204c close to the previous process places the pre-processed PCS product on the carrier close to the previous process again, waiting for the first deep pressing. Meanwhile, the suction nozzle 204c in the middle close to the previous process places the PCS product that has completed the first deep pressing on the carrier away from the previous process, waiting for the second deep pressing.

[0070] Step 6: Simultaneously, the upper pressure cylinder is activated, pushing the moving plate 304c forward. The spring plate 304g on the moving plate 304c, by compressing the spring, pushes the movable plate 304f forward. Consequently, the pressure bar 304i on the movable plate 304f also moves towards the PIN of the PCS product. When the spring is compressed to a certain depth, the arc-shaped surface 304i-1 on the pressure bar 304i begins to fit with the arc-shaped groove 304g-1 on the spring plate 304g. Then, the arc-shaped groove 304g-1 compresses the arc-shaped surface 304i-1, causing the arc-shaped surface 304i-1 to move upward, thereby causing the pressure bar 304i to tilt, so that the pressure head 304j presses down on the PIN of the PCS product. Subsequently, the electric cylinder 301 is activated, and the output end of the electric cylinder 301 drives the telescopic plate 301c on the slide table 301b to move, thereby driving the PIN push rod 302 on the telescopic plate 301c to advance towards the PCS product, pressing the PIN into place.

[0071] Step 7: After the second deep pressing is completed, the transport plate 204a moves in a circular motion again. The suction nozzle 204c near the previous process places the pre-processed PCS product on the carrier near the previous process again, waiting for the first deep pressing. The suction nozzle 204c in the middle near the previous process places the PCS product that has completed the first deep pressing on the carrier away from the previous process, waiting for the second deep pressing. Meanwhile, the suction nozzle 204c in the middle near the suction station 406 places the PCS product that has completed the second deep pressing on the suction station 406, waiting for the suction nozzle 204c on the transport plate 204a near the subsequent process to pick it up.

[0072] Step 8: Simultaneously, drive motor 403 starts, turntable station 404 rotates, and camera 401 inspects the PCS products passing through the camera port of camera 401. When the inspected product is qualified, the suction nozzle 204c on the transport plate 204a, which is close to the subsequent process, will pick up the qualified product on the suction station 406 and transfer it to the subsequent station. When the camera 401 detects a product as unqualified, the suction nozzle 204c on the transport plate 204a, which is close to the subsequent process, will grab the unqualified product and release it when it is transported to the top of the storage box 407, thereby collecting the defective product.

8. A method for conveying and pressing semiconductor devices, characterized in that: Using the semiconductor device conveying and pressing apparatus of claim 7, the following steps are performed: S1. The motor (201) starts, and the output end of the motor (201) drives the conveyor plate (204a) to move forward to the next station. The suction nozzle (204c) on the conveyor plate (204a) close to the previous process will pick up the PCS products that have been pre-processed in front and enter the ready-to-move state. S2. Next, the output end of the motor (201) drives the conveyor plate (204a) to start a semi-circular motion. The suction nozzle (204c) close to the previous process places the pre-processed PCS product on the carrier (303) close to the previous process, waiting for the first deep pressing. S3. At the same time, the upper pressure cylinder is activated and pushes the moving plate (304c) forward. The spring plate (304g) on ​​the moving plate (304c) pushes the movable plate (304f) forward by squeezing the spring. Then, the pressure bar (304i) on the movable plate (304f) also moves towards the PIN of the PCS product. When the spring is squeezed to a certain depth, the arc surface (304i-1) on the pressure bar (304i) and the arc groove (304g-1) on the spring plate (304g) begin to fit together. Then, the arc groove (304g-1) squeezes the arc surface (304i-1), causing the arc surface (304i-1) to move upward, thereby causing the pressure bar (304i) to start to tilt, so that the pressure head (304j) presses down on the PIN of the PCS product. S4. Subsequently, the electric cylinder (301) is started. The output end of the electric cylinder (301) drives the telescopic plate (301c) on the slide (301b) to move, thereby driving the PIN push rod (302) on the telescopic plate (301c) to push towards the PCS product and press the PIN into place. S5. After the first deep pressing is completed, the transport plate (204a) makes a circular motion again. The suction nozzle (204c) close to the previous process places the pre-processed PCS product on the carrier (303) close to the previous process again, waiting for the first deep pressing. Meanwhile, the suction nozzle (204c) in the middle close to the previous process places the PCS product that has completed the first deep pressing on the carrier (303) far away from the previous process, waiting for the second deep pressing. S6. At the same time, the upper pressure cylinder is activated and pushes the moving plate (304c) forward. The spring plate (304g) on ​​the moving plate (304c) pushes the movable plate (304f) forward by squeezing the spring. Then, the pressure bar (304i) on the movable plate (304f) also moves towards the PIN of the PCS product. When the spring is squeezed to a certain depth, the arc surface (304i-1) on the pressure bar (304i) and the arc groove (304g-1) on the spring plate (304g) begin to fit together. Then, the arc groove (304g-1) squeezes the arc surface (304i-1), causing the arc surface (304i-1) to move upward, thereby causing the pressure bar (304i) to start to tilt, so that the pressure head (304j) presses down on the PIN of the PCS product. Subsequently, the electric cylinder (301) is started, and the output end of the electric cylinder (301) drives the telescopic plate (301c) on the slide (301b) to move, thereby driving the PIN push rod (302) on the telescopic plate (301c) to push towards the PCS product and press the PIN into place; S7. After the second deep pressing is completed, the transport plate (204a) makes a circular motion again. The suction nozzle (204c) close to the previous process places the pre-processed PCS product on the carrier (303) close to the previous process again, waiting for the first deep pressing. The suction nozzle (204c) close to the previous process places the PCS product that has completed the first deep pressing on the carrier (303) away from the previous process, waiting for the second deep pressing. The suction nozzle (204c) close to the suction station (406) places the PCS product that has completed the second deep pressing on the suction station (406), waiting for the suction nozzle (204c) close to the subsequent process on the transport plate (204a) to pick it up. S8. At the same time, the drive motor (403) starts, the turntable station (404) rotates, and the camera (401) inspects the PCS products passing through the camera port (401). When the inspected product is qualified, the suction nozzle (204c) on the transfer plate (204a) near the subsequent process will pick up the qualified product on the suction station (406) and transfer it to the subsequent station. When the camera (401) detects that the product is unqualified, the suction nozzle (204c) on the transfer plate (204a) near the subsequent process will pick up the unqualified product and release it when it is transported to the top of the storage box (407), thereby collecting the defective product.
