[0003] However, in the process of producing and transporting chips, the chips need to be cleaned and other related operations. In the traditional chip cleaning process, the chips are usually placed horizontally, so that after cleaning the chips, the cleaning liquid cannot flow away in time, causing the cleaning liquid to remain on the chips. At the same time, when washing the cleaning liquid, the cleaning liquid is continuously flowing, so that the use rate of the cleaning liquid is small, and the consumption of the cleaning liquid is large. SUMMARY

[0018] Furthermore, a thrust spring is provided inside the sliding groove, with one end of the thrust spring fixed to the bottom of the sliding groove and the other end fixed to the sliding member.

[0038] Compared to existing technologies, this invention offers the following advantages: It enables chip cleaning during transport. Unlike existing technologies, this device uses a tilted and rotated mechanism to squeeze the cleaning fluid, allowing it to flow away from the chip surface and effectively removing foreign matter. Furthermore, by tilting the chips, this invention allows for precise dispensing of cleaning fluid while cleaning. Traditional chip cleaning devices continuously dispense cleaning fluid, while the quantitative dispensing device ensures consistent fluid distribution to each chip, conserving cleaning fluid.

[0053] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0054] like Figures 1 to 8 As shown, the present invention provides a mass production line for CPU chips, comprising: a transfer unit 4, a flipping and positioning unit 1, a cleaning box 2, and a cleaning assembly 3. The transfer unit 4 is adapted to transfer chips. The flipping and positioning unit 1 is adapted to carry and flip the chips. The cleaning box 2 is adapted to contain cleaning fluid. The cleaning assembly 3 is adapted to spray cleaning fluid onto the chips. Each of the above components will be described in detail below.

[0055] Transfer Department 4

[0056] The transfer unit 4 is fixed on a workbench. The transfer unit 4 is adapted to move the cleaning box 2 and the chip placed below the cleaning box 2 to achieve the effect of transferring the chip.

[0057] The structure of the transfer unit 4 is described in detail below. The transfer unit 4 includes a transfer component 41 and a support component 42. The transfer component 41 is fixedly connected to the cleaning box 2, and the transfer component 41 is threadedly connected to the support component 42. The support component 42 can drive the transfer component 41 to move horizontally. Since the transfer component 41 is fixedly connected to the cleaning box 2, when the support component 42 drives the transfer component 41 to move horizontally, the transfer component 41 can drive the cleaning box 2 to move horizontally synchronously, thereby achieving the effect of the transfer component 41 transferring the chip when the support component 42 is activated.

[0058] To achieve the above effects, the support assembly 42 includes: a positioning seat 421 fixed to the worktable, a horizontal slide rail 422 fixed to one end of the positioning seat 421, and a transfer motor 423 fixed to the other end of the positioning seat 421. A lead screw is fixed to the movable end of the transfer motor 423. The lead screw is located inside the horizontal slide rail 422 and is parallel to the length direction of the horizontal slide rail 422. When the transfer motor 423 starts, it can drive the lead screw to rotate circumferentially. The transfer assembly 41 includes: a sliding seat 411 and a connecting member 412. One end of the connecting member 412 is fixed to the sliding seat 411, and the other end is fixed to the cleaning box 2. The sliding seat 411 is threadedly connected to the lead screw, and both sides of the sliding seat 411 are respectively in contact with the two inner sidewalls of the horizontal slide rail 422. When the transfer motor 423 starts, it drives the lead screw to rotate. Since the sliding seat 411 is limited by the horizontal slide rail 422, the lead screw cannot drive the sliding seat 411 to rotate. Therefore, the thread of the lead screw pushes the sliding seat 411 to slide along the length of the horizontal slide rail 422. In this way, when the transfer motor 423 starts, it can ultimately drive the cleaning box 2 to move horizontally.

[0059] Cleaning box 2

[0060] The cleaning box 2 is fixed to one side of the connector 412 and is positioned above the flip positioning part 1. The cleaning box 2 is suitable for containing cleaning fluid. The cleaning box 2 can pass the cleaning fluid into the cleaning assembly 3 to provide the cleaning fluid required for cleaning the chip. At the same time, a water pipe can be connected to one side of the cleaning box 2 so that the water pipe can continuously replenish the cleaning fluid into the cleaning box 2.

[0061] Flip positioning part 1

[0062] The flip positioning part 1 is located below the cleaning box 2 and is fixedly connected to both sides of the cleaning box 2. The flip positioning part 1 is suitable for carrying the chip and driving the chip to flip. During the flipping process, the chip can be linked with the cleaning component 3. Specifically, the cleaning component 3 sprays cleaning fluid onto the upper surface of the chip in an inclined state. When the flip positioning part 1 drives the chip to flip to a vertical position, the chip drives the cleaning component 3 to be isolated from the cleaning box 2, and the cleaning fluid in the cleaning box 2 no longer fills the cleaning component 3, so that the cleaning component 3 stops spraying cleaning fluid onto the chip, thereby achieving quantitative dispensing of cleaning fluid and saving cleaning fluid.

[0063] The structure of the flip positioning part 1 is described in detail below. The flip positioning part 1 includes a support frame 11 and a flip disk 12 disposed inside the support frame 11. The upper end of the support frame 11 is fixed to both sides of the outer wall of the cleaning box 2, and the lower end of the support frame 11 extends downward to the bottom of the cleaning box 2. A flip motor 13 is fixed on the inner wall of one side of the lower end of the support frame 11, and the movable end of the flip motor 13 is horizontally arranged. One side of the flip disk 12 is fixed to the flip motor 13, and the other side is rotatably connected to the inner wall of the support frame 11 away from the flip motor 13. Through the above arrangement, when the flip motor 13 is started, it can drive the flip disk 12 to rotate around the rotation axis of the flip motor 13. The flip disk 12 is suitable for placing and positioning chips. Specifically, the flip disk 12 has a plurality of positioning holes 121, and the positioning holes 121 correspond to the pins of the chips. During transportation, the pins of the chips can be inserted into the corresponding positioning holes 121. The pins of the chips are interference-fitted with the positioning holes 121 to position the chips, and at the same time, the positioning holes 121 can straighten the pins of the chips.

[0064] Cleaning component 3

[0065] The cleaning component 3 is located at the lower end of the cleaning box 2 and above the flip plate 12. The cleaning component 3 has openings at both ends and is retractably mounted at the lower end of the cleaning box 2, allowing it to move in conjunction with the flip positioning part 1. Specifically, after the chip is mounted onto the flip positioning part 1, the flip positioning part 1 drives the chip to flip, causing the chip to push the cleaning component 3 back into the cleaning box 2. Simultaneously, the chip opens the lower opening of the cleaning component 3, and the cleaning component 3 sprays cleaning fluid onto the upper surface of the chip. When the cleaning component 3 retracts to its maximum travel, the cleaning box 2 seals the upper opening of the cleaning component 3, and the cleaning component 3 stops spraying cleaning fluid.

[0066] To achieve the effect of the cleaning component 3 spraying cleaning fluid onto the chip, the cleaning component 3 includes a cleaning cylinder 31. The cleaning box 2 also has an opening at its lower end, and the cleaning component 3 is retractably positioned within this opening. The cleaning cylinder 31 has an opening at its upper end and a water outlet at its lower end. Specifically, the upper opening of the cleaning component 3 is larger, allowing it to communicate with the inner cavity of the cleaning box 2, enabling the cleaning box 2 to replenish the cleaning component 3 with cleaning fluid. The lower water outlet of the cleaning component 3 is smaller, allowing it to spray cleaning fluid onto the chip through the lower opening. With this configuration, when the water outlet at the lower end of the cleaning cylinder 31 is open, the cleaning cylinder 31 sprays cleaning fluid onto the upper surface of the chip; when the chip pushes the cleaning cylinder 31 back into the cleaning box 2 to its maximum travel position, the cleaning box 2 seals the upper opening of the cleaning cylinder 31, and the cleaning cylinder 31 stops spraying cleaning fluid.

[0067] To achieve the function of opening the water outlet of the cleaning cylinder 31, a sliding groove 32 is provided at the lower end of the cleaning cylinder 31. The length direction of the sliding groove 32 is the same as the rotation direction of the flipping disk 12. A sliding member 33 is slidably disposed in the sliding groove 32. A through hole is provided on the sliding member 33, which corresponds to the water outlet of the cleaning cylinder 31. Specifically, when the through hole of the sliding member 33 and the water outlet of the cleaning cylinder 31 are completely intersected, the sliding member 33 completely blocks the water outlet of the cleaning cylinder 31; when the through hole of the sliding member 33 coincides with the water outlet of the cleaning cylinder 31, the cleaning liquid in the cleaning cylinder 31 can flow out sequentially through the water outlet of the cleaning cylinder 31 and the through hole of the sliding member 33. With the above arrangement, when the flipping disk 12 drives the chip to rotate to abut against the sliding member 33, the chip can push the sliding member 33 to slide along the sliding groove 32 until the through hole coincides with the water outlet of the cleaning cylinder 31, and the water outlet of the cleaning cylinder 31 is opened. To facilitate the reset of the sliding member 33, a thrust spring 34 is provided inside the sliding groove 32. One end of the thrust spring 34 is fixed to the bottom of the sliding groove 32, and the other end is fixed to the sliding member 33. With the thrust spring 34, after the chip is disengaged from the sliding member 33, the thrust spring 34 pushes the sliding member 33 to reset, and the sliding member 33 closes the water outlet of the cleaning cylinder 31.

[0068] To ensure that the cleaning cylinder 31 seals its upper opening when it retracts to its maximum stroke position, a sealing plate 21 is fixed to the inner wall of the cleaning box 2. The sealing plate 21 is horizontally positioned and corresponds to the upper opening of the cleaning cylinder 31. When the cleaning cylinder 31 retracts to its maximum stroke position, the sealing plate 21 seals the upper opening, isolating the cleaning cylinder 31 from the inner cavity of the cleaning box 2. This prevents the cleaning fluid from flowing into the cleaning box 2, thus achieving the effect of quantitatively dispensing the cleaning fluid into the cleaning box 2.

[0069] To achieve the effect of the cleaning cylinder 31 extending and retracting along the opening at the lower end of the cleaning box 2, two bellows tubes 22 are mirror-imagely arranged at the lower end of the sealing plate 21. The bellows tubes 22 can be unfolded or folded along their length. Two telescopic grooves 311 are mirror-imagely formed along the length of the end of the cleaning cylinder 31 away from the sliding member 33, with one telescopic groove 311 corresponding to one bellows tube 22. The end of the bellows tube 22 away from the sealing plate 21 is fixed to the bottom of the telescopic groove 311. With this arrangement, the sealing plate 21 pulls the cleaning cylinder 31 through the bellows tubes 22, keeping it within the opening at the lower end of the cleaning box 2. Under its own weight, the cleaning cylinder 31 extends downwards from the cleaning box 2, and the bellows tubes 22 are stretched and unfolded. When the chip is flipped to the point where the cleaning cylinder 31 is pushed upwards from below, it can be pushed back into the cleaning box 2, and the bellows tubes 22 fold until the upper opening of the cleaning cylinder 31 abuts against the sealing plate 21. To ensure the sealing of the cleaning cylinder 31, the sealing plate 21 is made of flexible material so that when the cleaning cylinder 31 comes into contact with the sealing plate 21, the cleaning cylinder 31 is sealed. At the same time, the side walls of the bellows tube 22 and the telescopic groove 311 are in close contact to ensure that the cleaning liquid in the cleaning box 2 does not enter the cleaning cylinder 31 when the sealing plate 21 seals the cleaning cylinder 31.

[0070] To prevent sedimentation in the cleaning solution during prolonged standing in the cleaning cylinder 31, which would affect its cleaning effect, a stirring shaft 35 is rotatably mounted on the bottom wall of the cleaning cylinder 31. Several stirring blades 351 are vertically fixed to the side wall of the stirring shaft 35. When the stirring shaft 35 rotates circumferentially, it drives the stirring blades 351 to rotate synchronously, thus stirring the cleaning solution in the cleaning cylinder 31. A linkage rod 23 is fixed to the lower end of the sealing plate 21, located directly above the stirring shaft 35. The diameter of the linkage rod 23 is smaller than the diameter of the stirring shaft 35. A linkage groove 352 is formed along the length of the stirring shaft 35, and the linkage rod 23 corresponds to the linkage groove 352, inserting into it along its length. The inner wall of the linkage groove 352 is provided with a spiral groove 353, and the side wall of the stirring shaft 35 is provided with a linkage block 231. The linkage block 231 is located in the spiral groove 353. When the chip pushes the cleaning cylinder 31 to retract into the cleaning box 2, the cleaning box 2 pushes the stirring shaft 35 closer to the sealing plate 21. The linkage rod 23 slides along the linkage groove 352, thereby causing the linkage block 231 to slide along the spiral groove 353. The linkage rod 23 pushes the stirring shaft 35 to rotate through the linkage block 231, thereby causing the stirring shaft 35 to drive the stirring blade 351 to stir the cleaning liquid in the cleaning cylinder 31.

[0071] It should be noted that during the process of the flipping disk 12 pushing the chip to flip from horizontal to vertical, the chip pushes the slider 33 to open the opening at the lower end of the cleaning cylinder 31 to release the cleaning fluid for cleaning the chip. When the flipping disk 12 pushes the chip to near vertical, the cleaning cylinder 31 abuts against the sealing plate 21. At this time, since the sealing plate 21 is made of flexible material, when the chip flips to vertical, the chip pushes the cleaning cylinder 31 to compress and deform the sealing plate 21, thereby ensuring that the sealing plate 21 seals the cleaning cylinder 31. At the same time, the chip will remain in a vertical state to allow the cleaning fluid on the chip surface to flow away. Then, the flipping disk 12 can continue to drive the chip to a downward position to continue draining the chip. Since the chip's pins are inserted into the positioning hole 121, the chip will not slip off the flipping disk 12. At the same time, during subsequent transportation, the chip's pins face upward to avoid damage to the pins.

[0072] The working process of a large-scale packaging production line for CPU chips shown in this embodiment is as follows: after the chip is installed on the flip disk 12, the support component 42 drives the transfer component 41 to move horizontally to transport the cleaning box 2.

[0073] During the movement of the transfer component 41, the flipping motor 13 drives the flipping disk 12 to flip so that one side of the chip abuts against the sliding member 33. The sliding member 33 slides along the sliding groove 32 to open the lower opening of the cleaning cylinder 31, and the cleaning cylinder 31 sprays cleaning liquid onto the upper surface of the chip.

[0074] The rotating disk 12 drives the chip to continue rotating, and the chip pushes the cleaning cylinder 31 back into the cleaning box 2. The linkage rod 23 pushes the stirring shaft 35 to rotate circumferentially, and the stirring blade 351 stirs the cleaning liquid in the cleaning cylinder 31.

[0075] When the cleaning cylinder 31 retracts to abut against the sealing plate 21, the chip flips to a vertical position, the cleaning cylinder 31 is isolated from the cleaning box 2, and the cleaning box 2 stops spraying cleaning fluid.

[0076] As the flipping disc 12 continues to drive the chip to flip downwards, the chip disengages from the sliding member 33. The thrust spring 34 pushes the sliding member 33 to close the lower opening of the cleaning tube. At the same time, the chip disengages from the washing tube 31, and the washing tube 31 pulls the accordion tube 22 to unfold.

[0077] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
