If the silicon pile is detected as unqualified, the silicon pile can be discarded, and in the discarding process, only the unqualified single silicon pile can be discarded, the qualified silicon pile can be retained on the suction block, and the qualified silicon pile can be supplemented at the discarding position. The storage tube stores multiple layers of silicon piles, and whenever a layer of silicon pile is consumed, the multiple layers of silicon piles can be pushed upwards by a thickness of a layer of silicon pile.

DETAILED DESCRIPTION

[0032] Clearly, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts are within the scope of the present application.

[0033] Embodiment: The present application provides a braided silicon pile brush inspection machine, such as Figures 1-3As shown, it comprises a chip frame conveying seat 1, two dispensing mechanisms 2, an electric sliding table 3, a bidirectional mechanical arm 4, a visual detection mechanism 5, a punching mechanism 6, a ribbon feeding mechanism 7, a waste collecting box 8, a chip frame feeding machine 9 and a mounting table 10. The electric sliding table 3 is fixedly installed on the mounting table 10, and the two chip frame conveying seats 1 are fixedly installed on the electric sliding table 3. The electric sliding table 3 is used for conveying the bidirectional movement of the two dispensing mechanisms 2. The dispensing mechanisms 2 are fixedly installed on the mounting table 10 and are used for dispensing the chip frame on the left chip frame conveying seat 1. The bidirectional mechanical arm 4 is fixedly installed on the mounting table 10 and is provided with a suction block 4a. The bidirectional mechanical arm 4 is used to drive the suction block 4a to move in the vertical direction and perpendicular to the length direction of the electric sliding table 3. The ribbon feeding mechanism 7 is fixedly installed on the mounting table 10 and is used to convey the ribbon silicon stack to the punching mechanism 6. The punching mechanism 6 is fixedly installed on the mounting table 10 and is used to punch upward the ribbon silicon stack conveyed to the punching position. The suction block 4a is used to suction and fix the punched silicon stack. The bottom of the suction block 4a is provided with a plurality of suction holes, and the inside of the suction block 4a is provided with an air duct connected with the suction holes. The air outlet of the air duct is connected with an external air source. The visual detection mechanism 5 and the waste collecting box 8 are located between the punching mechanism 6 and the electric sliding table 3. The visual detection mechanism 5 is used to take a photo of the silicon stack suctioned on the bottom of the suction block 4a for detection. If the detection result is unqualified, the suction block 4a moves above the waste collecting box 8, the suction block 4a stops suction, and the unqualified silicon stack falls into the waste collecting box 8. The waste collecting box 8 is used to collect the unqualified silicon stack. If the detection 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 feeding machine 9 is fixedly installed on the mounting table 10 and is used to convey the chip frame toward the chip frame conveying seat 1. When it is needed to install the silicon stack on the chip frame, the whole chip frame is first conveyed to the left chip frame conveying seat 1 by the chip frame feeding machine 9, and the position on the chip frame conveying seat 1 where the silicon stack needs to be installed is dispensed by the dispensing mechanism 2. The chip frame placed on the right chip frame conveying seat 1 is the chip frame that has been dispensed. 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 to approach each other by the electric sliding table 3, 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 sliding table 3 is driven to reset.

[0034] And the chip frame on the right side of the chip frame conveying seat 1, need to move through the bidirectional manipulator 4 drive suction block 4a, after the silicon stack on the punching mechanism 6 is punched, clamping and conveying, first to the visual inspection mechanism 5 for detection, according to the actual situation, to carry on the subsequent qualified or unqualified movement process.

[0035] If the detection is unqualified, it is likely that one of the silicon stacks is unqualified, and if the air source is disconnected, the multiple silicon stacks on the suction block 4a will fall at the same time, which will cause the undamaged silicon stacks to be wasted, and in the long run, it will increase the cost of manufacturing. If the damaged silicon stack is removed by the mechanism and discarded, and the normal silicon stack is not supplemented, it will lead to the lack of chip frame, and finally still cause the chip to be defective. Therefore, after discarding, normal silicon stacks can be supplemented, such as Figures 4-8As shown, it also includes the support plate 11, the elastic telescopic pipe 12, the storage pipe 13, the jacking plate 14, the pushing mechanism 15, the gate mechanism 16 and the cross-direction pushing mechanism 17, the waste collecting box 8 includes the frame 8a and the shell 8b, the frame 8a is fixedly installed on the mounting table 10 through the mounting rack, the shell 8b is located directly below the frame 8a, the storage pipe 13 is 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 pipe 13, the support plate 11 is located above the gate mechanism 16, the support plate 11 is provided with the material passing hole 11a, the material passing hole 11a is located directly above the storage pipe 13, the support plate 11 is fixedly installed on the frame 8a through the elastic telescopic pipe 12, the elastic telescopic pipe 12 is used for providing the vertical elastic force upward for the support plate 11, the cross-direction pushing mechanism 17 is fixedly installed on the frame 8a, one end of the cross-direction pushing mechanism 17 is in transmission connection with the elastic telescopic pipe 12, the other end of the cross-direction pushing mechanism 17 is in transmission connection with the storage pipe 13, when the elastic telescopic pipe 12 is compressed downward, the cross-direction pushing mechanism 17 pushes the storage pipe 13 upward, when the storage pipe 13 is pushed upward to the final position, the silicon stack located at the top in the storage pipe 13 will be in contact with the bottom of the suction nozzle of the suction block 4a. Wherein, in the process of the upward movement of the storage pipe 13, the storage pipe 13 will automatically open the gate mechanism 16. And the top of the storage pipe 13 is closed through the gate mechanism 16 in order to avoid the damaged silicon stack from being stuck into the top of the storage pipe 13, the jacking plate 14 is vertically slidably installed in the storage pipe 13, the jacking plate 14 has friction force with the contact surface of the storage pipe 13, the pushing mechanism 15 is fixedly installed on the frame 8a, the pushing mechanism 15 is used for vertically pushing the jacking plate 14 upward. When it is needed to replace the damaged silicon stack detected on the suction block 4a, first, the suction block 4a is driven by the bidirectional mechanical arm 4, so that the bottom silicon stack of the suction block 4a is in contact with the top of the support plate 11, wherein the damaged silicon stack will move to the position directly opposite the material passing hole 11a, at this time, the gas is cut off through the external gas source, the damaged silicon stack will fall through the material passing hole 11a, and the normal silicon stack will remain on the support plate 11. And the fallen silicon stack will pass through the frame 8a and fall on the shell 8b.

[0036] Subsequently, continue to push down through suction block 4a, will make the support plate 11 downward movement, while the elastic telescopic tube one 12 will be compressed, and in the elastic telescopic tube one 12 movement, the elastic telescopic tube one 12 will be driven by the wrong direction push mechanism 17 to drive the storage tube 13 to slide up, in the storage tube 13 upward movement, the storage tube 13 will be automatically opened by the gate mechanism 16, and in the storage tube 13 upward push 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 inhales, so that all the silicon stacks are sucked on the bottom of the suction block 4a, and then the suction block 4a is transported by the bidirectional mechanical hand 4. After the storage tube 13 is reset downward, the push mechanism 15 will push up the vertically distributed multiple silicon stacks upward by the thickness of a silicon stack.

[0037] That is, after discarding the damaged silicon stack, a normal silicon stack can be quickly replenished, saving cost 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 suction block 4a, the bottom of the suction block 4a can push the top silicon stack downward to avoid rigid extrusion and ensure the safety of the silicon stack.

[0039] Because the gate mechanism 16 must be opened during the descent of the support plate 11, and the top of the storage tube 13 needs to be inserted into the material hole 11a, therefore, as shown in Figure 9 The wrong direction push mechanism 17 includes a hinged seat 17a, a hinged rod 17b, a lifting seat 17c, a sliding rail 17d, a sliding column one 17e and a sliding column two 17f. The hinged seat 17a is fixedly installed on the frame 8a, the middle part of the hinged rod 17b is hinged to the hinged seat 17a, the storage tube 13 is fixedly installed on the top of the lifting seat 17c, the sliding rail 17d is fixedly installed on the frame 8a, the sliding rail 17d is slidably connected to one side of the lifting seat 17c, the two sides of the hinged rod 17b are provided with a waist-shaped hole, the sliding column one 17e is fixedly installed on the upper half of the elastic telescopic tube one 12, the sliding column two 17f is fixedly installed on the hinged seat 17a, and the sliding column one 17e and the sliding column two 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 one 12 to move downward, so that the sliding column one 17e moves downward, the sliding column one 17e pulls the hinged rod 17b to rotate around the hinged seat 17a, the hinged seat 17a pushes the sliding column two 17f to move upward, and the lifting seat 17c drives the storage tube 13 to slide upward vertically, so that the storage tube 13 can be inserted into the material hole 11a.

[0040] At the same time, as shown in Figure 9As shown, the gate mechanism 16 includes two hinged frames 16a and two gate plates 16b, the gate plates 16b are rotatably installed on the hinged frames 16a, the hinged frames 16a are fixedly installed on the frame 8a, the bottom of the two hinged frames 16a abuts the top of the storage tube 13, when the storage tube 13 passes between the two hinged frames 16a, the inner side of the two hinged frames 16a inclines, and the end of the two hinged frames 16a contacts the outer side of the storage tube 13. When the storage tube 13 moves upward, the top of the storage tube 13 will push the two hinged frames 16a, so that the two hinged 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 hinged frames 16a will rotate inward, so that the hinged frames 16a cover the top of the storage tube 13.

[0041] In order to enable the pushing mechanism 15 to push the lifting plate 14 upward, so that the multi-layer silicon stack can be pushed upward, and if the pushing mechanism 15 pushes upward at a speed greater than the lifting of the lifting plate 14 while the support plate 11 is compressed, so that the pushing mechanism 15 can push the lifting plate 14, it is necessary to ensure that the lifting plate 14 has an excess movement of being pushed upward, for this purpose, as shown in Figure 10 and Figure 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 push seat 15e, a friction plate 15f, a guide pipe 15h, and a rotating seat 15j. The lifting rod 15a is located directly below the storage pipe 13 and is used to lift the lifting plate 14 inside the storage pipe 13 upward. The lifting rod 15a is inserted into the guide pipe 15h. The outer edge of the guide pipe 15h is provided with a gap for the large friction wheel 15c to pass through. The outer edge of the large friction wheel 15c is in contact with the lifting rod 15a. The side of the lifting rod 15a close to the large friction wheel 15c is rough. The rotation of the large friction wheel 15c can push the lifting rod 15a to slide up and down along the guide pipe 15h. The large friction wheel 15c and the small friction wheel 15d are both fixedly installed on the rotating shaft of the large friction wheel 15c. The large friction wheel 15c is fixedly installed inside the frame 8a. The friction plate 15f is in contact with the small friction wheel 15d. When the friction plate 15f moves upward, it will rotate the small friction wheel 15d. The friction plate 15f is fixedly installed on the displacement seat of the elastic push seat 15e. The elastic push seat 15e is fixedly installed on the upper half of the elastic telescopic pipe 12. The one-way limiting mechanism 15b is fixedly installed 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 guide pipe 15h to move upward. When the elastic telescopic pipe 12 is compressed, the elastic telescopic pipe 12 will push the elastic push seat 15e downward. The elastic push seat 15e will push the friction plate 15f to move vertically downward. The friction plate 15f will rotate the small friction wheel 15d and the large friction wheel 15c, so that the lifting rod 15a can lift the lifting plate 14 inside the storage pipe 13 upward, and the lifting plate 14 can push the plurality of silicon stacks to move vertically upward.

[0042] Although the lifting rod 15a only rises by the thickness of one silicon stack during the entire process of the operation of the lifting mechanism 15, the initial movement speed is accelerated, which can lift the lifting plate 14 at the beginning and ensure that the top silicon stack can be in contact with the bottom of the suction block 4a, which ensures that the suction block 4a and the rising silicon stack can be suctioned tightly. Avoid the situation that cannot be contacted due to the thickness difference of multiple silicon stacks. Moreover, the lifting mechanism 15 must adopt this structure, because only this structure can make the lifting rod 15a push upward at a certain speed and height within one second.

[0043] When the storage pipe 13 moves downward to reset, the lifting plate 14 will be in contact with the top of the lifting rod 15a which has moved upward by the thickness of one silicon stack. The height of the lifting rod 15a during the entire process is the thickness of one silicon stack. The height of the initial upward movement of the lifting rod 15a to lift the lifting plate 14 is lower than the thickness of one silicon stack.

[0044] When the elastic tube 12 is restored, the friction plate 15f is pulled upward, and due to the locking effect of the one-way limiting mechanism 15b, the jacking rod 15a cannot be pulled downward, and the rigid friction between the friction plate 15f and the small friction wheel 15d is avoided by the elastic push seat 15e, so that the friction plate 15f can be reset upward.

[0045] If the jacking plate 14 only supports the silicon stack through the friction effect between the jacking plate 14 and the storage tube 13, over a long period of time, no contact friction force will occur between the jacking plate 14 and the storage tube 13, and in order to avoid this situation, as shown in Figure 12 The jacking plate 14 is provided with a protrusion penetrating the storage tube 13, and the elastic compression mechanism 18 is used to abut against the protrusion. The elastic compression mechanism 18 includes a rotating pressing plate 18a and a torsional spring rotator 18b. The rotating pressing plate 18a is rotatably installed on the torsional spring rotator 18b, and the torsional spring rotator 18b is used to apply an elastic force to the rotating pressing plate 18a to approach the protrusion. The rotating pressing plate 18a abuts against the jacking plate 14, which plays a role of friction support for the jacking plate 14. The torsional spring rotator 18b is internally provided with a torsional spring, one end of which is connected with the rotating pressing plate 18a, and the other end is installed on the housing of the torsional spring rotator 18b.

[0046] As shown in Figure 13 The one-way limiting mechanism 15b includes an elastic tube 15b1, a trapezoidal plug 15b2, and a ratchet wheel 15b3. The ratchet wheel 15b3 is fixedly installed on the inner wall of the frame 8a, the trapezoidal plug 15b2 is fixedly installed on the end of the elastic tube 15b1, and the ratchet wheel 15b3 is fixedly installed on the rotating shaft of the rotating seat 15j. The ratchet wheel 15b3 is provided with a plurality of clamping grooves for inserting the trapezoidal plug 15b2 in the circumferential direction. The inclined end of the trapezoidal plug 15b2 faces upward, and the flat end of the trapezoidal plug 15b2 faces downward. When the ratchet wheel 15b3 rotates clockwise, the ratchet wheel 15b3 pushes the trapezoidal plug 15b2, so that the elastic tube 15b1 is compressed. When the ratchet wheel 15b3 needs to rotate counterclockwise, the trapezoidal plug 15b2 cannot be pushed.

[0047] As shown in Figure 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 installed on the upper half of the elastic telescopic pipe 12, the guide column 15e2 is slidably installed on the lifting guide plate 15e1, the spring 15e3 is sleeved on the guide column 15e2, the mounting plate 15e4 is fixedly installed on one end of the guide column 15e2, and the other end of the guide column 15e2 is fixedly installed with a limiting plate. The spring 15e3 is used to provide the mounting plate 15e4 with an elastic force away from the lifting guide plate 15e1. The friction plate 15f is fixedly installed on the mounting plate 15e4. When the elastic telescopic pipe 12 is compressed, the lifting guide plate 15e1 will move downward, that is, the friction plate 15f is driven downward by the mounting plate 15e4. At this time, when the friction plate 15f is upwardly rubbed, the friction plate 15f will be in contact with the small friction wheel 15d, so that the friction plate 15f moves 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] As shown in the figure, Figure 5 The outer side of the frame body 8a is fixedly provided with an electric sliding table 19, which is used to push the frame body 8a to move horizontally. Since the bottom of the suction block 4a is provided with two rows of protrusions, when any one row of silicon stacks is damaged, the position of the material feeding hole 11a can be adjusted by the electric sliding table 19 to ensure that it can adapt to the damaged silicon stacks at different positions.

[0049] In use, when it is necessary to install silicon stacks on the chip frame, the whole chip frame is first conveyed to the left chip frame conveying seat 1 by the chip frame conveying machine 9, and the positions of the chip frame conveying seat 1 where the silicon stacks need to be installed are glued by the glue dispensing mechanism 2. The chip frame placed on the right chip frame conveying seat 1 is the one that has been glued. 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 to approach each other by the electric sliding table 3, 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 sliding table 3 is driven to reset.

[0050] If the detection result is unqualified, the suction block 4a moves to the upper side of the waste collecting box 8, the suction block 4a is cut off, and the unqualified silicon stacks fall into the waste collecting box 8. The waste collecting box 8 is used to collect the unqualified silicon stacks. If the detection is qualified, the suction block 4a will transport the silicon stacks to the chip frame on the chip frame conveying seat 1.

[0051] When the damaged silicon stack on the suction block 4a needs to be replaced, the suction block 4a is first driven by the bidirectional mechanical arm 4 so that the bottom silicon stack of the suction block 4a is in contact with the top of the support plate 11, wherein the damaged silicon stack will move to a position directly opposite the through hole 11a, at this time, the gas is disconnected by the external gas source, the damaged silicon stack will fall through the through hole 11a, while the normal silicon stack will remain on the support plate 11, and the falling silicon stack will pass through the frame 8a and fall onto the shell 8b.

[0052] Subsequently, the suction block 4a is continuously pushed down, which will make the support plate 11 move downward, and the elastic expansion pipe 12 will be compressed, while the elastic expansion pipe 12 is moving, the elastic expansion pipe 12 will drive the storage pipe 13 to slide upward through the cross-direction lifting mechanism 17, in the process of upward movement of the storage pipe 13, the storage pipe 13 will automatically open the gate mechanism 16, and when the storage pipe 13 is pushed upward to the final position, the silicon stack at the top of the storage pipe 13 will be in contact with 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 to the bottom of the suction block 4a, and then the suction block 4a is transported by the bidirectional mechanical arm 4.

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

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