Description

[0002] The silicon stack is a component used to be installed on the chip frame. Before leaving the factory, the silicon material is generally assembled in the form of tape. After the chip factory purchases the taped silicon stack, the removed silicon stack needs to be surface inspected before installation.

[0003] The Chinese patent disclosed: CN201510453017.7 Tape silicon stack brush inspection machine, which replaces the manual inspection method, uses a brush inspection wheel, a polarity meter and an alarm for automatic inspection.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment: The present invention provides a braided silicon stack brush inspection machine, such as Figure 1-Figure 3As shown, it includes a chip frame conveying seat 1, two glue dispensing mechanisms 2, an electric slide 3, a bidirectional manipulator 4, a visual inspection mechanism 5, a punching mechanism 6, a tape feeding mechanism 7, a waste collection box 8, a chip frame feeder 9 and a mounting table 10, the electric slide 3 is fixedly mounted on the mounting table 10, the two chip frame conveying seats 1 are fixedly mounted on the electric slide 3, the electric slide 3 is used to convey the two glue dispensing mechanisms 2 for bidirectional movement, the glue dispensing mechanism 2 is fixedly mounted on the mounting table 10, the glue dispensing mechanism 2 is used to dispense glue to the chip frame on the left chip frame conveying seat 1, the bidirectional manipulator 4 is fixedly mounted on the mounting table 10, the bidirectional manipulator 4 is provided with a suction block 4a, the bidirectional manipulator 4 is used to drive the suction block 4a to move in the vertical direction and in the length direction perpendicular to the electric slide 3, the tape feeding mechanism 7 is fixedly mounted on the mounting table 10, and the tape feeding mechanism 7 is used to convey the tape silicon stack to the punching The cutting mechanism 6 is fixedly mounted on the mounting table 10, and the cutting mechanism 6 is used for punching and ejecting the braided silicon stack transported to the punching position, and the suction block 4a is used for sucking and fixing the ejected silicon stack, and a plurality of suction holes are arranged at the bottom of the suction block 4a, and an air duct connected to the suction holes is arranged inside the suction block 4a, and the air suction port of the air duct is connected to an external air source, and the visual inspection mechanism 5 and the waste collection box 8 are located between the cutting mechanism 6 and the electric slide 3, and the visual inspection mechanism 5 is used for photographing and inspecting the silicon stack adsorbed by the bottom of the suction block 4a, and if the inspection result is unqualified, the suction block 4a moves to the top of the waste collection box 8, and the suction block 4a is cut off, and the unqualified silicon stack falls into the waste collection box 8, and the waste collection box 8 is used for collecting the unqualified silicon stack, and if the inspection is qualified, the suction block 4a transports the silicon stack and places it on the chip frame on the chip frame conveying seat 1. The chip frame feeder 9 is fixedly mounted on the mounting table 10, and the chip frame feeder 9 is used to feed the chip frame toward the chip frame conveying seat 1. When it is necessary to install a silicon stack on the chip frame, the entire chip frame is first conveyed to the chip frame conveying seat 1 on the left by the chip frame feeder 9, and the position where the silicon stack needs to be installed on the chip frame conveying seat 1 is glued by the glue dispensing mechanism 2. The chip frame that has been glued is placed on the chip frame conveying seat 1 on the right. When the chip frame on the left chip frame conveying seat 1 needs to move to the right chip frame conveying seat 1, the two chip frame conveying seats 1 are driven inwardly by the electric slide 3 to fit together, and then the chip frame is conveyed to the conveying belt on the other side by the conveying belt on the chip frame conveying seat 1. When the conveying is completed, the conveying of the chip frame is completed, and finally the electric slide 3 is used to drive and reset.

[0034] The chip frame located on the right chip frame conveying seat 1 needs to be moved by the bidirectional manipulator 4 to drive the suction block 4a to clamp and convey the silicon pile punched on the punching mechanism 6, and first convey it to the visual inspection mechanism 5 for inspection, and then carry out the subsequent qualified or unqualified movement process according to the actual situation.

[0035] If the test fails, it is most likely that one of the silicon stacks is unqualified. If the gas source is disconnected, multiple silicon stacks on the clamping block 4a will fall off at the same time, which will cause the undamaged silicon stacks to be wasted. In the long run, it will increase the manufacturing cost. If the damaged silicon stack is removed and discarded by the mechanism without replenishing the normal silicon stack, it will cause a shortage on the chip frame, which will eventually cause chip defects. Therefore, it is necessary to replenish the normal silicon stack after discarding it, such as Figure 4-8As shown, it also includes a support plate 11, an elastic telescopic tube 12, a storage tube 13, a lifting plate 14, a push mechanism 15, a gate mechanism 16 and a staggered push mechanism 17 installed. The waste collection box 8 includes a frame 8a and a shell 8b. The frame 8a is fixedly installed on the mounting table 10 through a mounting frame, and the shell 8b is located directly below the frame 8a. The storage tube 13 can be vertically slidably installed in the frame 8a. The gate mechanism 16 is fixedly installed on the frame 8a. The gate mechanism 16 covers the top of the storage tube 13. The support plate 11 is located above the gate mechanism 16. A feeding hole 11a is provided on the support plate 11. The feeding hole 11a is located at Right above the storage tube 13, the support plate 11 is fixedly mounted on the frame 8a through the elastic telescopic tube 12. The elastic telescopic tube 12 is used to provide an upward vertical elastic force to the support plate 11. The wrong-direction push-up mechanism 17 is fixedly mounted on the frame 8a. One end of the wrong-direction push-up mechanism 17 is transmission-connected with the elastic telescopic tube 12, and the other end of the wrong-direction push-up mechanism 17 is transmission-connected with the storage tube 13. When the elastic telescopic tube 12 is compressed downward, the wrong-direction push-up mechanism 17 pushes the storage tube 13 upward. When the storage tube 13 is pushed upward to the final position, the silicon stack at the top of the storage tube 13 will contact the bottom of the suction nozzle of the suction block 4a. In the process of the storage tube 13 moving upward, the storage tube 13 will automatically open the gate mechanism 16. The purpose of closing the top of the storage tube 13 by the gate mechanism 16 is to prevent the damaged silicon stack from being stuck in the top of the storage tube 13. The lifting plate 14 can be installed in the storage tube 13 in a vertically sliding manner. The contact surface between the lifting plate 14 and the storage tube 13 has friction. The pushing mechanism 15 is fixedly installed on the frame 8a, and the pushing mechanism 15 is used to push the lifting plate 14 vertically upward. When it is necessary to replace the silicon stack detected as damaged on the suction block 4a, the suction block 4a is first driven by the bidirectional manipulator 4, so that the silicon stack at the bottom of the suction block 4a contacts the top of the support plate 11, wherein the damaged silicon stack will move to the position facing the feed hole 11a. At this time, the gas source is cut off, and the damaged silicon stack will fall through the feed hole 11a, while the normal silicon stack will remain on the support plate 11. The fallen silicon stack will pass through the frame 8a and fall onto the shell 8b.

[0036] Then, the support plate 11 will move downwards by continuing to push downwards through the suction block 4a, and the elastic telescopic tube 12 will be compressed at the same time. When the elastic telescopic tube 12 moves, the elastic telescopic tube 12 will drive the storage tube 13 to slide upwards through the staggered pushing mechanism 17. During the upward movement of the storage tube 13, the storage tube 13 will automatically open the gate mechanism 16. When the storage tube 13 is pushed upwards to the final position, the silicon pile at the top of the storage tube 13 will contact the bottom of the suction nozzle of the suction block 4a. Finally, the suction block 4a sucks air so that all the silicon piles are sucked at the bottom of the suction block 4a, and then the suction block 4a is driven by the bidirectional manipulator 4 for transportation. After the storage tube 13 is reset downwards, the pushing mechanism 15 will lift the vertically distributed multiple silicon piles upwards by the thickness of one silicon pile.

[0037] That is, after the damaged silicon stack is discarded, a normal silicon stack can be quickly replenished, saving costs and avoiding discarding all the silicon stacks adsorbed on the suction block 4a.

[0038] At the same time, the silicon stack is supported by the lifting plate 14. If the top silicon stack collides with the clamping block 4a, the bottom of the clamping block 4a can push the top silicon stack downward to avoid rigid extrusion and ensure the safety of the silicon stack.

[0039] Since the gate mechanism 16 must be opened during the descending process of the support plate 11, the top of the storage tube 13 needs to be inserted into the feeding hole 11a. Fig. 9 As shown, the staggered pushing mechanism 17 includes an articulated seat 17a, an articulated rod 17b, a lifting seat 17c, a slide rail 17d, a slide column 17e and a slide column 2 17f. The articulated seat 17a is fixedly mounted on the frame 8a, the middle part of the articulated rod 17b is hinged to the articulated seat 17a, the storage tube 13 is fixedly mounted on the top of the lifting seat 17c, the slide rail 17d is fixedly mounted on the frame 8a, the slide rail 17d is slidably connected to one side of the lifting seat 17c, waist-shaped holes are provided on both sides of the articulated rod 17b, the slide column 17e is fixedly mounted on the upper half of the elastic telescopic tube 12, the slide column 2 17f is fixedly mounted on the articulated seat 17a, and the slide column 17e and the slide column 2 17f are respectively inserted into the two waist-shaped holes. When the support plate 11 moves downward, the support plate 11 will drive the elastic telescopic tube 12 to move downward, so that the sliding column 17e moves downward, and the sliding column 17e will pull the hinge rod 17b to rotate around the hinge seat 17a. The hinge seat 17a will push the sliding column 17f to move upward, and drive the storage tube 13 to slide vertically upward through the lifting seat 17c, so that the storage tube 13 can be inserted into the feeding hole 11a.

[0040] At the same time, if Fig. 9As shown, the gate mechanism 16 includes an articulated frame 16a and two gate plates 16b. The gate plates 16b are rotatably mounted on the articulated frame 16a. The articulated frame 16a is fixedly mounted on the frame body 8a. The bottoms of the two articulated frames 16a are in contact with the top of the storage tube 13. When the storage tube 13 passes through the two articulated frames 16a, the inner sides of the two articulated frames 16a are tilted, and the ends of the two articulated frames 16a are in contact with the outer sides of the storage tube 13. When the storage tube 13 moves upward, the top of the storage tube 13 will push the two articulated frames 16a, so that the two articulated frames 16a are pushed open, that is, the gate mechanism 16 is opened while the storage tube 13 moves upward. When the storage tube 13 moves downward to the final position, the two articulated frames 16a will rotate inward, so that the articulated frames 16a cover the top of the storage tube 13.

[0041] In order to enable the lifting mechanism 15 to lift the lifting plate 14 upward, so that the multi-layer silicon stack can be pushed upward, and at the same time, if the lifting mechanism 15 is lifted upward at a speed greater than the lifting plate 14 while the support plate 11 is compressed, so that the lifting mechanism 15 can lift the lifting plate 14, it is ensured that the lifting plate 14 can have an excessive movement of being lifted, for this purpose, Fig.10 and Fig.11As shown, the lifting mechanism 15 includes a lifting rod 15a, a one-way limiting mechanism 15b, a large friction wheel 15c, a small friction wheel 15d, an elastic pushing seat 15e, a friction plate 15f, a guide tube 15h and a rotating seat 15j. The lifting rod 15a is located directly below the storage tube 13. The lifting rod 15a is used to lift the lifting plate 14 inside the storage tube 13 upward. The lifting rod 15a is inserted into the guide tube 15h. The outer edge of the guide tube 15h is provided with an avoidance gap for the large friction wheel 15c to pass through. The outer edge of the large friction wheel 15c contacts the lifting rod 15a. The side of the lifting rod 15a close to the large friction wheel 15c is a rough surface structure. The large friction wheel 15c rotates, which will enable the large friction wheel 15c to push the lifting rod 15a along the The conduit 15h slides up and down, the large friction wheel 15c and the small friction wheel 15d are fixedly mounted on the rotating shaft of the large friction wheel 15c, the large friction wheel 15c is fixedly mounted inside the frame 8a, the friction plate 15f is in contact with the small friction wheel 15d, and when the friction plate 15f moves upward, it will push the small friction wheel 15d to rotate, the friction plate 15f is fixedly mounted on the displacement seat of the elastic push seat 15e, and the elastic push seat 15e is fixedly mounted on the upper half of the elastic telescopic tube 12, and the one-way limiting mechanism 15b is fixedly mounted on the frame 8a. The one-way limiting mechanism 15b is used to limit the rotating shaft of the rotating seat 15j in one direction, so that the rotating shaft can only rotate clockwise, that is, the large friction wheel 15c can only push the conduit 15h to move upward. When the elastic telescopic tube 12 is compressed, the elastic telescopic tube 12 will push the elastic push seat 15e downward, and the elastic push seat 15e will push the friction plate 15f to move vertically downward. The friction plate 15f will push the small friction wheel 15d and the large friction wheel 15c to rotate, so that the lifting rod 15a can lift the lifting plate 14 inside the storage tube 13 upward, so that the lifting plate 14 pushes the multiple silicon stacks upward to move vertically.

[0042] Although the lifting rod 15a only rises by the thickness of a silicon pile during the entire operation of the lifting mechanism 15, the movement speed is accelerated at the beginning, so that the lifting plate 14 can be lifted at the beginning, ensuring that the most ejected silicon pile can collide with the bottom of the suction block 4a, which ensures that the suction block 4a and the rising silicon pile can be sucked tightly. Avoid the situation where the silicon piles cannot be contacted due to the difference in thickness. And the lifting mechanism 15 must adopt this structure, because only this structure can make the lifting rod 15a push upward at a speed and height within one second.

[0043] When the storage tube 13 finally moves downward to reset, the lifting plate 14 will contact the top of the lifting rod 15a that has moved upward by the thickness of a silicon pile. The height to which the lifting rod 15a rises in the whole process is the thickness of the silicon pile, while at the beginning, the lifting rod 15a slightly lifts the lifting plate 14 to a height lower than the thickness of a silicon pile.

[0044] When the elastic telescopic tube 12 is restored, the friction plate 15f will be pulled upward. Due to the locking effect of the one-way limit mechanism 15b, the lifting rod 15a will not be pulled downward. At the same time, the elastic push seat 15e will avoid rigid friction between the friction plate 15f and the small friction wheel 15d, so that the friction plate 15f can be reset upward.

[0045] If the lifting plate 14 supports the silicon stack only by the friction between the lifting plate 14 and the storage tube 13, there will be no contact friction between the lifting plate 14 and the storage tube 13 in the long run. In order to avoid this situation, Fig.12 As shown, it also includes an elastic clamping mechanism 18, and the lifting plate 14 is provided with a convex block that passes through the storage tube 13. The elastic clamping mechanism 18 is used to contact the convex block. The elastic clamping mechanism 18 includes a rotating pressing plate 18a and a torsion spring rotator 18b. The rotating pressing plate 18a can be rotatably installed on the torsion spring rotator 18b, and the torsion spring rotator 18b is used to apply an elastic force close to the convex block to the rotating pressing plate 18a. Through the conflict between the rotating pressing plate 18a and the lifting plate 14, the lifting plate 14 is provided with a friction support. A torsion spring is installed inside the torsion spring rotator 18b, one end of the torsion spring is connected to the rotating pressing plate 18a, and the other end can be installed on the housing of the torsion spring rotator 18b.

[0046] like Fig.13 As shown, the one-way limiting mechanism 15b includes an elastic telescopic tube 15b1, a trapezoidal plug 15b2 and a ratchet 15b3, the ratchet 15b3 is fixedly mounted on the inner wall of the frame 8a, the trapezoidal plug 15b2 is fixedly mounted on the end of the elastic telescopic tube 15b1, the ratchet 15b3 is fixedly mounted on the rotating shaft of the rotating seat 15j, the ratchet 15b3 is provided with a plurality of slots for the trapezoidal plug 15b2 to be inserted along the circumferential direction, the inclined end of the trapezoidal plug 15b2 faces the upper side, and the flat end of the trapezoidal plug 15b2 faces the lower side, when the ratchet 15b3 rotates clockwise, the ratchet 15b3 will push the trapezoidal plug 15b2, so that the elastic telescopic tube 15b1 is compressed, and when the ratchet 15b3 needs to rotate counterclockwise, the trapezoidal plug 15b2 will not be pushed.

[0047] like Fig.14As shown, the elastic push seat 15e includes a lifting guide plate 15e1, a guide column 15e2, a spring 15e3 and a mounting plate 15e4. The lifting guide plate 15e1 is fixedly mounted on the upper half of the elastic telescopic tube 12. The guide column 15e2 can be mounted on the lifting guide plate 15e1 in a horizontally slidable manner. The spring 15e3 is sleeved on the guide column 15e2. The mounting plate 15e4 is fixedly mounted on one end of the guide column 15e2. The other end of the guide column 15e2 is fixedly mounted with a limit plate. The spring 15e3 is used to provide an elastic force for the mounting plate 15e4 to move away from the lifting guide plate 15e1. The friction plate 15f is fixedly mounted on the mounting plate 15e4. When the elastic telescopic tube 12 is compressed, the lifting guide plate 15e1 will move downward, that is, the friction plate 15f is driven to move downward through the mounting plate 15e4. Among them, when the friction plate 15f is moved upward, the friction plate 15f will contact and collide with the small friction wheel 15d, so that the friction plate 15f moves toward the side away from the small friction wheel 15d. That is, in this process, the spring 15e3 will be compressed and the mounting plate 15e4 will drive the guide column 15e2 to slide along the lifting guide plate 15e1.

[0048] like Figure 5 As shown, an electric slide 19 is fixedly arranged on the outer side of the frame 8a, and the electric slide (19) is used to push the frame 8a to move horizontally. Since the bottom of the suction block 4a has two rows of protrusions, when the silicon stacks in any row are damaged, the position of the material passing hole 11a can be adjusted by the electric slide 19 to ensure that it can adapt to the damaged silicon stacks at various positions.

[0049] During use, when it is necessary to install a silicon stack on the chip frame, the chip frame feeder 9 is first used to transport the entire chip frame to the chip frame conveying seat 1 on the left, and the glue dispensing mechanism 2 is used to dispense glue at the position on the chip frame conveying seat 1 where the silicon stack needs to be installed. The chip frame that has been glued is placed on the chip frame conveying seat 1 on the right. When the chip frame on the left chip frame conveying seat 1 needs to move to the right chip frame conveying seat 1, the electric slide 3 drives the two chip frame conveying seats 1 to move inward and fit together, and then the conveying belt on the chip frame conveying seat 1 is used to transport the chip frame to the conveying belt on the other side. When the conveying is completed, the conveying of the chip frame is completed, and finally the electric slide 3 is used to drive and reset.

[0050] If the test result is unqualified, the suction block 4a moves to the top of the waste collection box 8, the suction block 4a cuts off the air, and the unqualified silicon pile falls into the waste collection box 8. The waste collection box 8 is used to collect the unqualified silicon pile. If the test result is qualified, the suction block 4a transports the silicon pile and places it on the chip frame on the chip frame conveying seat 1.

[0051] When it is necessary to replace the damaged silicon stack on the suction block 4a, the suction block 4a is first driven by the bidirectional manipulator 4 so that the bottom silicon stack of the suction block 4a contacts the top of the support plate 11, wherein the damaged silicon stack will move to a position facing the feed hole 11a. At this time, the air source is cut off through the external air source, and the damaged silicon stack will fall through the feed hole 11a, while the normal silicon stack will remain on the support plate 11, and the fallen silicon stack will pass through the frame 8a and fall onto the shell 8b.

[0052] Then, the support plate 11 will move downwards by continuing to push downwards through the suction block 4a, and the elastic telescopic tube 12 will be compressed. When the elastic telescopic tube 12 moves, the elastic telescopic tube 12 will drive the storage tube 13 to slide upwards through the misaligned push mechanism 17. During the upward movement of the storage tube 13, the storage tube 13 will automatically open the gate mechanism 16. When the storage tube 13 is pushed upwards to the final position, the silicon stack at the top of the storage tube 13 will contact the bottom of the suction nozzle of the suction block 4a. Finally, the suction block 4a sucks air so that all the silicon stacks are sucked at the bottom of the suction block 4a, and then the suction block 4a is driven by the bidirectional manipulator 4 for transportation.

[0053] When the elastic expansion tube 12 is compressed, it will also drive the push mechanism 15 to move, so that the friction plate 15f drives the small friction wheel 15d to rotate, and the guide tube 15h will quickly push the lifting plate 14 upward at a faster speed than the lifting plate 14, so that the lifting plate 14 drives the multi-layer silicon stack to move slightly upward, ensuring that the bottom of the suction block 4a can eventually collide with the top silicon stack. When the storage tube 13 is finally reset downward, the lifting plate 14 will contact the top of the lifting rod 15a that has moved upward by the thickness of a silicon stack.

[0054] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
