[0017] This specific embodiment is a fully automated chip double-sided inspection device, the structural schematic diagram of which is shown below. Figures 1-12As shown, the device includes a base 1, a feeding station 2 mounted on the base 1, a first lifting assembly 3 mounted on the base 1 for conveying a tray to the feeding station 2, a first X-axis assembly 4 mounted on the base 1 for transferring the tray on the feeding station 2 in the X-axis direction, a first detection camera 5 slidably mounted on the base 1 for detecting chips in the tray, a material handling assembly 6 mounted on the base 1 for moving the tray, a second X-axis assembly 7 mounted on the base 1, and a first receiving station 8 for collecting qualified products, a second receiving station 9 for replenishing qualified products, and a third receiving station 10 for collecting defective products. A second lifting assembly is mounted on the base 1 at a position corresponding to the first receiving station 8, the second receiving station 9, and the third receiving station 10. The first detection camera 5 is slidably mounted on the base 1 via a lead screw module, which enables the first detection camera 5 to reciprocate in the Y-axis direction.

[0018] The first X-axis assembly 4 includes a first support column 401 fixedly mounted on the base 1, a first linear motor 402 fixedly mounted on the first support column 401, a first Z-axis assembly 403 symmetrically mounted on the first linear motor 402, and a plurality of first suction pens 404 fixedly mounted on each first Z-axis assembly 403. The first linear motor 402 drives the first Z-axis assembly 403 and multiple first suction pens 404 to reciprocate in the X-axis direction; Each first Z-axis assembly 403 includes a first U-shaped plate 4031 driven by a first linear motor 402, a first mounting plate 4032 fixedly mounted on the first U-shaped plate 4031, a first motor 4033 fixedly mounted on the first mounting plate 4032, a first lead screw 4034 fixedly mounted on the output end of the first motor 4033, a first nut seat 4035 threadedly mounted on the first lead screw 4034, a first cover plate 4036 fixedly mounted on the side of the first nut seat 4035 away from the first mounting plate 4032, and a pen suction mounting plate 4037 fixedly mounted on the first cover plate 4036. The pen suction mounting plate 4037 is used to mount a plurality of first pens 404. When the first motor 4033 drives the first lead screw 4034 to rotate clockwise, it can drive the first nut seat 4035 to move downward. During the downward movement of the first nut seat 4035, it can drive the first cover plate 4036 to move downward. During the downward movement of the first cover plate 4036, it can drive the pen mounting plate 4037 and the first pen 404 to move downward. Similarly, when the first motor 4033 drives the first lead screw 4034 to rotate counterclockwise, the first suction pen 404 can move upward. That is, the first Z-axis assembly 403 can drive the first suction pen 404 to reciprocate up and down on the Z-axis. At the same time, under the drive of the first linear motor 402, multiple first suction pens 404 reciprocate in the X-axis direction. The first cover plate 4036 is slidably mounted on the first mounting plate 4032 via the first sliding assembly 405. The first sliding assembly 405 includes a first slide rail 4051 fixedly mounted on the first mounting plate 4032 and a first slider 4052 fixedly mounted on the first cover plate 4036. The first cover plate 4036 is slidably mounted on the first mounting plate 4032 through the cooperation of the first slider 4052 and the first slide rail 4051. During the movement of the first cover plate 4036, the first slider 4052 can slide on the first slide rail 4051. With the cooperation of the first slide rail 4051 and the first slider 4052, the movement of the first cover plate 4036 can be guided, making the first cover plate 4036 move more smoothly.

[0019] The second lifting assembly has the same structure as the first lifting assembly 3. The first lifting assembly 3 includes a motor bracket 301 fixedly installed inside the base 1, a second motor 302 fixedly installed on the motor bracket 301, a second lead screw 303 fixedly installed at the output end of the second motor 302, a second nut seat 304 threadedly connected to the second lead screw 303, a lifting plate 305 fixedly installed on the outer surface of the second nut seat 304, a lifting rod 306 fixedly installed on the top of the lifting plate 305, and a push plate 307 fixedly installed on the top of the lifting rod 306. The top of the lifting rod 306 passes through the top of the base 1 and extends above the base 1, and the push plate 307 is located above the base 1. When the second motor 302 drives the second lead screw 303 to rotate clockwise, it can drive the second nut seat 304 to move upward. During the upward movement of the second nut seat 304, it can drive the lifting plate 305 to move upward. During the upward movement of the lifting plate 305, it can drive the lifting rod 306 and the push plate 307 at its top to move upward. Similarly, when the second motor 302 drives the second lead screw 303 to rotate counterclockwise, it can drive the lifting rod 306 and the push plate 307 at its top to move downwards. That is, under the action of the second motor 302, the push plate 307 can make up-down reciprocating motion.

[0020] The material handling assembly 6 includes a U-shaped frame 601 fixedly mounted on the base 1, a second linear motor 602 fixedly mounted on the U-shaped frame 601, a second U-shaped plate 603 driven by the second linear motor 602, connecting vertical plates 604 fixedly mounted at both ends of the second U-shaped plate 603, a cylinder mounting plate 605 fixedly mounted at the bottom of the connecting vertical plate 604, a lifting cylinder 606 fixedly mounted on the cylinder mounting plate 605, a third U-shaped plate 607 fixedly mounted at the telescopic end of the lifting cylinder 606, a gripper cylinder 608 fixedly mounted on the third U-shaped plate 607, two gripper mounting plates 609 driven by the gripper cylinder 608 and symmetrically arranged, and a gripper 610 fixedly mounted on the gripper mounting plate 609. Under the action of the second linear motor 602, the gripper 610 can be driven to reciprocate in the X-axis direction; The lifting cylinder 606 is activated to move the third U-shaped plate 607 downward. During the downward movement of the third U-shaped plate 607, the gripper cylinder 608, gripper mounting plate 609, and gripper 610 can be moved downward. When the gripper 610 moves to the position to grip the material tray, the lifting cylinder 606 stops working. The gripper cylinder 608 drives the two gripper mounting plates 609 to move relative to each other, causing the two gripper mounting plates 609 to move closer to the material tray. During the movement, the gripper mounting plates 609 can drive the grippers 610 at both ends to move closer to the material tray until the side of the gripper 610 contacts the side of the material tray. The gripper cylinder 608 is then closed. At this time, the bottom of the gripper 610 contacts the bottom of the material tray, and the material tray is gripped by the gripper 610. Since both ends of the two gripper mounting plates 609 have grippers 610, the four grippers 610 are located at the four corners of the material tray, making the grippers 610 grip the material tray stably and reliably. Meanwhile, under the action of the second linear motor 602, it can drive the gripper 610 and the material tray it grips to reciprocate in the X-axis direction.

[0021] The second X-axis assembly 7 includes a second support column 701 fixedly mounted on the base 1, a third linear motor 702 fixedly mounted on the second support column 701, a second Z-axis assembly 703 symmetrically mounted on the third linear motor 702, a pen suction assembly 704 mounted on one of the second Z-axis assemblies 703, and a second detection camera 705 mounted on the other second Z-axis assembly 703. The third linear motor 702 drives the second Z-axis assembly 703 and the pen suction assembly 704 / second detection camera 705 to reciprocate in the X-axis direction; Each second Z-axis assembly 703 includes a fourth U-shaped plate 7031 driven by a third linear motor 702, a second mounting plate 7032 fixedly mounted on the fourth U-shaped plate 7031, a third motor 7033 fixedly mounted on the second mounting plate 7032, a third lead screw 7034 fixedly mounted on the output end of the third motor 7033, a third nut seat 7035 threadedly mounted on the third lead screw 7034, and a connecting plate 7036 fixedly mounted on the side of the third nut seat 7035 away from the second mounting plate 7032; The pen suction assembly 704 includes an adjusting cylinder 7041 fixedly mounted on a connecting plate 7036 of one of the second Z-axis assemblies 703, a plurality of pen suction brackets 7042 whose positions are adjusted by the adjusting cylinder 7041, a pen suction cylinder 7043 fixedly mounted on each pen suction bracket 7042, and a second pen suction 7044 fixedly mounted on the pen suction cylinder 7043. Under the action of the adjusting cylinder 7041, the position of the suction pen bracket 7042 can be adjusted, thereby adjusting the position of the second suction pen 7044, so that the position of the second suction pen 7044 is adjusted to correspond to the position of the chip on the material tray. Then, under the action of the suction pen cylinder 7043, the second suction pen 7044 is driven to move downward to absorb the chip on the material tray. The second detection camera 705 is fixedly mounted on the connecting plate 7036 of another second Z-axis assembly 703; When the third motor 7033 drives the third lead screw 7034 to rotate clockwise, it can drive the third nut seat 7035 to move downward. During the downward movement of the third nut seat 7035, it can drive the connecting plate 7036 to move downward. During the downward movement of the connecting plate 7036, it can drive the pen suction assembly 704 / second detection camera 705 to move downward. Similarly, when the third motor 7033 drives the third lead screw 7034 to rotate counterclockwise, it can cause the pen suction assembly 704 / second detection camera 705 to move upward; That is, the second Z-axis assembly 703 can drive the pen suction assembly 704 / second detection camera 705 to reciprocate up and down on the Z-axis, while the third linear motor 702 drives the pen suction assembly 704 / second detection camera 705 to reciprocate in the X-axis direction. The connecting plate 7036 is slidably mounted on the second mounting plate 7032 via the second sliding assembly 706. The second sliding assembly 706 includes a second slide rail 7061 fixedly mounted on the second mounting plate 7032 and a second slider 7062 fixedly mounted on the connecting plate 7036. The connecting plate 7036 is slidably mounted on the second mounting plate 7032 through the cooperation of the second slider 7062 and the second slide rail 7061. During the movement of the connecting plate 7036, the second slider 7062 can slide on the second slide rail 7061. With the cooperation of the second slide rail 7061 and the second slider 7062, the movement of the connecting plate 7036 can be guided, making the connecting plate 7036 more stable during the movement, thereby making the pen suction assembly 704 and the second detection camera 705 more stable during the movement. The feeding station 2, the first receiving station 8, the second receiving station 9 and the third receiving station 10 have the same structure. The feeding station 2, the first receiving station 8, the second receiving station 9 and the third receiving station 10 all include a support frame 201 fixedly installed on the base 1, a guide rail 202 fixedly installed on the support frame 201, a limiting member 203 fixedly installed on the guide rail 202, a support member 204 for supporting the material tray, a clamp 205 for clamping the material tray and a fourth linear motor 206 for driving the clamp 205 to move. The support member 204 includes a U-shaped seat 2041 fixedly installed on the top of the guide rail 202 and a support rod 2042 rotatably installed on the U-shaped seat 2041 via a rotating shaft. A torsion spring is installed on the rotating shaft, and the bottom of the end of the support rod 2042 away from the U-shaped seat 2041 is an arc-shaped surface. The feeding station 2, the first receiving station 8, the second receiving station 9 and the third receiving station 10 are each equipped with two guide rails 202. Each guide rail 202 is mounted on the base 1 by at least two support frames 201. This arrangement is beneficial to the stability of the guide rail 202. Each guide rail 202 is provided with two support members 204, so there are a total of four support members 204 on the two guide rails 202. The four support members 204 can support the four corners of the material tray, so that the material tray can remain stable when it is supported. When the second motor 302 drives the second lead screw 303 to rotate clockwise, it can drive the second nut seat 304 to move upward. During the upward movement of the second nut seat 304, it can drive the lifting plate 305 to move upward. During the upward movement of the lifting plate 305, it can drive the lifting rod 306 and its top push plate 307 to move upward. During the upward movement of the push plate 307, it drives the material tray to move upward synchronously. During the upward movement of the material tray, it can contact the arc-shaped surface of the support rod 2042. Since the support rod 2042 is rotatably installed, it can push the arc-shaped surface of the support rod 2042 during the upward movement of the material tray. When the tray moves upward and is positioned above the support rod 2042, the support rod 2042 rotates back to a horizontal position under the reset action of the torsion spring. Then, the second motor 302 drives the second lead screw 303 to rotate clockwise, causing the push plate 307 and the tray to descend. During the descent, the tray rests on the support rod 2042. At this time, the four corners of the tray are supported by the support rods 2042 of the four support members 204. By repeating the above steps, the tray can be collected at the feeding station 2, the first receiving station 8, the second receiving station 9, and the third receiving station 10. The support component 204 on the feeding station 2 can be replaced by a receiving cylinder and a support block instead of the U-shaped seat 2041 and the support rod 2042. Specifically, during the process of the push plate 307 driving the material tray to move upward, the receiving cylinder drives the support block to retract in advance. When the material tray moves to the receiving position, the receiving cylinder drives the support block to extend and contact the bottom of the material tray to support the material tray.

[0022] Each guide rail 202 is provided with two limiting members 203, so there are a total of four limiting members 203 on the two guide rails 202. The four limiting members 203 can limit the four corners of the material tray, so that the material tray remains stable when it is collected. A sensor, such as a distance sensor, can also be installed on one of the limiting components 203. By sensing the received distance information, the number of material trays collected can be determined, and then transmitted to the controller and displayed on the screen so that the staff can collect the material trays. Under the action of the fourth linear motor 206, the clamp 205 and the material tray it grips can be driven to reciprocate at the feeding station 2, the first receiving station 8, the second receiving station 9 and the third receiving station 10.

[0023] Since the feeding station 2 and the first receiving station 8 are stations for detecting chips, the trays on the feeding station 2 and the first receiving station 8 need to move back and forth frequently. Therefore, the fourth linear motor 206 of the feeding station 2 and the first receiving station 8 are each equipped with two, and the clamps 205 on the two fourth linear motors 206 are located at both ends of the guide rail 202 respectively; this can improve the transfer efficiency of the trays.

[0024] It also includes a material tray frame 11 installed on the base 1, with material support cylinders 12 on both sides of the material tray frame 11, and a material support plate 13 fixedly installed at the output end of the material support cylinder 12. A third lifting component with the same structure as the first lifting component 3 is installed on the base 1. The tray rack 11 is used to store empty trays. During the process of the tray being moved upward by the push plate 307 of the third lifting component, the material support cylinder 12 drives the material support plate 13 to retract in advance. When the tray moves to the storage position, the material support cylinder 12 drives the material support plate 13 to extend and contact the bottom of the tray to support the tray. The supported tray waits for the material handling component 6 to transport it.

[0025] In use, this invention first uses the first lifting assembly 3 to send a tray filled with chips to be tested onto the clamp 205 of the feeding station 2. Then, under the action of the fourth linear motor 206, the tray is moved along the guide rail 202 to below the first X-axis assembly 4. Then, under the action of the two first Z-axis assemblies 403, multiple first suction pens 404 are driven to move downwards, which can simultaneously adsorb two rows of chips on the tray. Then, under the action of the first Z-axis assembly 403, the first suction pens 404 and the chips they adsorb are moved upwards. At the same time, the first linear motor 402 drives the first Z-axis assembly 403, the first suction pens 404 and the chips to move to the first... Above the detection camera 5, the first detection camera 5 can be moved to the detection position via the lead screw module. The first detection camera 5 detects the bottom of the chip. The detection result of the first detection camera 5 is transmitted to the controller. Then, the first linear motor 402 drives the first Z-axis assembly 403, the first suction pen 404 and the chip to the feeding station 2. The first Z-axis assembly 403 moves the chip that has undergone the first detection down onto the material tray and releases the suction pen 404 from the chip. Then, the first Z-axis assembly 403 moves the suction pen up. Under the action of the fourth linear motor 206, the material tray and the detected chip are transferred to the other end of the feeding station 2. Then, the material handling assembly 6 transfers the aforementioned material tray to the clamp 205 of the first receiving station 8. Under the action of the fourth linear motor 206, the material tray and chip are moved to the area below the second inspection camera 705. The second inspection camera 705 inspects the top of the chip and transmits the inspection result to the controller. The material handling assembly 6 transfers the empty material tray on the material tray rack 11 to the clamp 205 of the third receiving station 10. The defective chip, after two inspections, is picked up from the material tray by the second suction pen 7044. The defective chip is then transferred to the empty material tray of the third receiving station 10 via the second X-axis assembly 7. The material handling assembly 6 transfers the empty material tray on the material tray rack 11 to the clamp 205 on the second receiving station 9, and the second X-axis assembly 7 transfers the qualified chips to the material tray on the second receiving station 9 for later use. After the defective chips are removed from the tray after the second inspection, the tray will have empty slots for placing chips. The qualified chips placed on the tray of the second receiving station 9 will be transferred to the tray of the first receiving station 8 by the second X-axis assembly 7. When the tray of the first receiving station 8 is full of qualified chips, the fourth linear motor 206 on the first receiving station 8 will drive the clamp 205 and the tray to move to the end of the guide rail 202 away from the material handling assembly 6 for collection. After the tray on the third receiving station 10 is full of defective chips, the fourth linear motor 206 drives the clamp 205 and the tray to move to the end of the guide rail 202 away from the material handling component 6 for collection. After the tray on the second receiving station 9 is filled with qualified chips, the fourth linear motor 206 drives the clamp 205 and the tray to move to the end of the guide rail 202 away from the material handling component 6 for collection.

[0026] In summary, this application can achieve automatic feeding through the first lifting component 3, double-sided detection through the first detection camera 5 and the second detection camera 705, automatic collection of qualified chips through the first receiving station 8, and automatic collection of defective chips through the third receiving station 10. That is, this application can achieve automatic detection, automatic classification and collection of qualified and defective chips, thereby improving production efficiency.
