Description
Technical Field
[0001] The present invention relates to the technical field of semiconductor detection, and specifically to a vision detection device for semiconductor module packaging. Background Art
[0002] A semiconductor module is a device that uses a certain semiconductor material as the working substance to generate stimulated emission. It is a part of a semiconductor laser. Semiconductor packaging refers to the process of processing wafers that have passed testing into independent chips according to product models and functional requirements. Vision detection is to use a machine to replace the human eye for measurement and judgment. Vision detection refers to converting the captured target into an image signal through a machine vision product and transmitting it to a dedicated image processing system. It has inestimable value in detecting defects and preventing defective products from being delivered to consumers. Therefore, packaged semiconductors usually need to be inspected by a vision detection device to determine their quality.

[0041] In the description of the present invention, unless otherwise clearly defined, words such as setting, installing, connecting, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.
[0042] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments:
[0043] A vision inspection device for semiconductor module packaging provided by the present invention, as Figures 1 to 12 shown, includes a base 1. A moving component 2 is slidably connected to the top end of the base 1. A synchronous belt 5 is rotatably arranged on the inner wall of the base 1. The top end of the synchronous belt 5 is fixedly connected to the bottom end of the moving component 2;
[0044] The moving component 2 includes a sliding seat 201. Two lower chambers 205 are communicated with the bottom end of the sliding seat 201. A group of air bags 206 are respectively communicated with the side walls of each group of lower chambers 205. A second flap 208 is hinged at the connection of the air bag 206 and the lower chamber 205. A first flap 207 is hinged at one end of the air bag 206 away from the lower chamber 205. An opening is provided at the connection of the air bag 206 and the first flap 207. A dust suction head 204 is arranged at the top end of the sliding seat 201. The dust suction head 204 is communicated to the inside of the lower chamber 205. The bottom end of the sliding seat 201 is fixedly connected to the top end of the synchronous belt 5. A fixing block 202 is slidably sleeved on the top end of the sliding seat 201. A groove is provided at the position where the sliding seat 201 contacts the fixing block 202. Two magnetic strips 209 are fixedly connected to the top end of the sliding seat 201. The magnetic strips 209 are tightly adsorbed on the bottom end of the fixing block 202. The lower chamber 205 is communicated to the inside of the groove. A chip 203 is arranged at the top end of the fixing block 202. Two racks 311 are fixedly connected to the bottom end of the sliding seat 201.
[0045] The sliding seat 201 is pushed by the synchronous belt 5 to slide on the top of the base 1, so that the sliding seat 201 slides from one end of the base 1 to the other end. During the process of the sliding seat 201 moving towards the detection mechanism 4, the sliding seat 201 pulls the airbag 206, causing the airbag 206 to be deployed, thereby generating a negative pressure inside the airbag 206. At this time, the second flap 208 flips open, so that the negative pressure inside the airbag 206 sucks external air into the airbag 206, allowing the air to pass over the surface of the chip 203 and taking away the dust on the surface of the chip 203. Then these airflows enter the inside of the dust suction head 204, and then enter the airbag 206. After the chip 203 is removed by the blanking mechanism 3, the synchronous belt 5 pushes the sliding seat 201 to slide back in the reverse direction, so that the sliding seat 201 compresses the airbag 206, thereby generating a high-pressure state inside the airbag 206, causing the second flap 208 to close, and at this time the first flap 207 is pushed by the air pressure to flip open, so that the air is discharged from the inside of the airbag 206. The fixing block 202 is adsorbed on the top of the sliding seat 201 through the magnetic strip 209, so that the corresponding fixing block 202 can be quickly replaced when visually detecting chips 203 of different models. During the movement of the sliding seat 201, the negative pressure inside the lower bin 205 causes the negative pressure to generate an adsorption force on the fixing block 202, so that the fixing seat is separated from the sliding seat 201 during the visual detection process, resulting in damage to the chip 203.
[0046] Please refer specifically to Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 and Figure 6 At one end of the base 1, there is a blanking mechanism 3. The blanking mechanism 3 includes two groups of toothed discs 301. The two groups of toothed discs 301 are rotatably connected to the side wall of the base 1. A group of rotating arms 302 are respectively fixedly connected to the side walls of each group of toothed discs 301. The ends of the two groups of rotating arms 302 are rotatably connected to a hoisting plate 303. The top of the hoisting plate 303 is communicated with an air pump, and the bottom of the hoisting plate 303 is communicated with multiple suction heads 304. A set of sleeves 305 are respectively sleeved on the outer walls of each group of suction heads 304. A silica gel pad 310 is fixedly connected to the bottom of the sleeve 305. Multiple sliders 306 extending into the inside of the suction head 304 are fixedly connected to the inner wall of the sleeve 305. Two groups of clamping blocks 308 are respectively slidably connected to the top of each group of fixing blocks 202. A group of second springs 309 are respectively fixedly connected to the side walls of each group of clamping blocks 308, and the ends of each group of second springs 309 are fixedly connected to the inner wall of the fixing block 202.
[0047] After the sliding seat 201 passes through the detection mechanism 4, the sliding seat 201 continues to move in the direction of the blanking mechanism 3, so that the sliding seat 201 drives the rack 311 to engage with the gear disk 301, thereby pushing the gear disk 301 to rotate. During the rotation of the gear disk 301, the rotating arm 302 is driven to turn over, so that the rotating arm 302 drives the lifting plate 303 to turn over. And because the center of gravity of the lifting plate 303 itself is relatively low, the suction head 304 always faces downward. Then, as the rotating arm 302 turns over, the lifting plate 303 is reversed above the sliding seat 201, so that the sleeve 305 contacts the chuck. Then, as the lifting plate 303 continues to press down, the suction head 304 compresses the first spring 307. When the first spring 307 is compressed to the limit, the downward pressure of the suction head 304 is transmitted to the top of the slider 306, thereby pushing the sleeve 305 downward to push the chuck, so that the chuck slides on the top of the fixed block 202 and compresses the second spring 309. When the bottom end of the sleeve 305 fits on the top of the fixed block 202, at this time the silica gel pad 310 fits on the top of the PCB of the chip 203. Under the action of the air pump, suction is generated inside the suction head 304, so that the chip 203 is sucked, and the chuck is blocked by the sleeve 305 and does not generate a clamping force on the chip 203. Then, when the sliding seat 201 slides back and resets in the reverse direction, the sliding seat 201 drives the rack 311 to move in the reverse direction, thereby causing the gear disk 301 to rotate in the reverse direction, so that the rotating arm 302 turns over in the reverse direction, and the lifting plate 303 turns over in the reverse direction. During the rising process of the lifting plate 303, the first spring 307 gradually rebounds, so that the sleeve 305 is always located between the two sets of clamping blocks 308, and the chip 203 slides into the sleeve 305 under the drive of the suction head 304. When the slider 306 slides to the bottom end of the inner wall of the suction head 304 and cannot slide any further, the slider drives the sleeve 305 to rise, so that the sleeve 305 is separated from the two sets of clamping blocks 308, thereby causing the second spring 309 to rebound and push the clamping blocks 308 to reset.
[0048] Please refer particularly to Figure 1 、 Figure 2 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12, a detection mechanism 4 is fixedly connected to the top end of the base 1. The detection mechanism 4 includes two groups of fixing sleeves 401. The inner wall of each group of fixing sleeves 401 is fixedly connected with multiple groups of conduits 402. The top ends of the multiple groups of conduits 402 communicate with a light collecting cover 403. A vision detector main body 407 is provided on the inner wall fixing sleeve 401 of the light collecting cover 403. A group of first refracting mirrors 404 are respectively fixedly connected to the inner walls of each group of conduits 402. A second refracting mirror 405 is fixedly connected to the inner wall of the conduit 402 beside the first refracting mirror 404. Two groups of LED lamp beads 406 are fixedly connected to the inner wall of the conduit 402 near the bottom end. An elastic strip 408 is slidably sleeved on the bottom end of the fixing sleeve 401. Multiple groups of lenses 409 are fixedly connected to the outer wall of the elastic strip 408. The lenses 409 are attached to the bottom end of the fixing sleeve 401. A rotating sleeve 410 is rotatably connected to the bottom end of the fixing sleeve 401. A motor 413 is fixedly connected to the bottom end of the fixing sleeve 401. The output end of the motor 413 is fixedly connected to the bottom end of the rotating sleeve 410. Multiple groups of sliding rods 411 are slidably sleeved on the inner wall of the rotating sleeve 410. One end of the sliding rod 411 extends to the outer wall of the rotating sleeve 410. The end of the sliding rod 411 outside the rotating sleeve 410 is hinged to the side wall of the lens 409. One end of the sliding rod 411 inside the rotating sleeve 410 is fixedly connected with a telescopic spring 412. The end of the telescopic spring 412 is fixedly connected to the inside of the rotating sleeve 410.
[0049] When the sliding seat 201 drives the chip 203 to pass under the detection mechanism 4, the synchronous belt 5 stops, enabling the chip 203 to have sufficient time to be detected. The light of the LED lamp beads 406 passes through the lens 409 and irradiates on the surface of the chip 203. Since the color of the lens 409 is different, the light passing through the lens 409 presents corresponding colors, thus facilitating detection under different light conditions. The motor 413 drives the rotating sleeve 410 to rotate, causing the rotating sleeve 410 to drive the sliding rod 411 to rotate, and then the sliding rod 411 drives the lens 409 to rotate. During the rotation of the lens 409, the elastic strip 408 slides at the bottom of the fixed sleeve 401, enabling the lens 409 to accurately rotate to the bottom of the conduit 402. During the rotation of the lens 409, since the position of the lens 409 is restricted by the elastic strip 408, the distance between the lens 409 and the rotating sleeve 410 changes, causing the sliding rod 411 to slide out of the rotating sleeve 410, thereby compressing the telescopic spring 412. When the distance between the lens 409 and the rotating sleeve 410 decreases, the telescopic spring 412 rebounds, and at this time, the sliding rod 411 slides into the interior of the rotating sleeve 410, ensuring that the sliding rod 411 can always push the lens 409 to rotate during the rotation of the rotating sleeve 410 driven by the motor 413. After the light irradiates on the surface of the chip 203, it is reflected back into the conduit 402. After being refracted by the first refracting mirror 404 and the second refracting mirror 405, the light is captured by the vision detector main body 407, enabling the vision detector main body 407 to collect and analyze the image information of multiple groups of chips 203 simultaneously, improving the detection efficiency.
[0050] During use, by pushing the sliding seat 201 to move through the synchronous belt 5, the sliding seat 201 stretches the airbag 206, generating negative pressure inside the airbag 206, causing the air flow to pass above the chip 203 and driving the dust to be inhaled into the airbag 206. Thus, the dust outside the package of the chip 203 is sucked away, avoiding misjudgment during subsequent vision detection, preventing unnecessary losses during the production of the chip 203, improving the yield rate, reducing costs, and enhancing the production efficiency of the chip 203. The parts not involved in this device are the same as or can be implemented using existing technologies.
[0051] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art in the technical field, various changes can be made without departing from the purpose of the present invention.
