Description

Technical Field

[0001] This utility model relates to the field of chip boxes, and in particular to a chip box that facilitates chip clamping. Background Technology

[0002] A wafer cassette is a piece of equipment used to mold cores from core sand. It can be made of wood, plastic, metal, or other materials. The design of the wafer cassette is determined based on factors such as the characteristics of the core, production volume, and production conditions. In semiconductor manufacturing, the wafer cassette primarily serves to place and transport wafers. To simplify transportation and minimize the risk of contamination, chip manufacturers use wafer cassettes to handle and store wafers.

[0003] For example, Chinese Patent No. CN220765166U discloses a chip box for easy chip clamping, including a box body with an end cap connected to it via a snap-fit ​​structure; a placement plate is horizontally fixedly connected inside the box body, and the placement plate has placement slots of different widths; a fixing cylinder corresponding to the position of the placement slot is fixedly connected to the inner wall of the end cap, and a sliding cylinder is provided inside the fixing cylinder; a limiting frame is fixedly connected downward to the sliding cylinder, and the size of the limiting frame corresponds to the size of the placement slot. While this solves the problem of "being able to clamp chips that are not suitable for use," it is not a complete solution. The chip box is designed to clamp chips of the same size and facilitate the clamping of chips in batches. However, in actual use, the structure of "tightening screw 11 to move the limiting frame 9 downward under the action of nut 14 and sliding cylinder 8, the limiting frame 9 clamps onto the chip to limit the chip, and at the same time the spring 15 inside the limiting frame 9 contacts the chip to press it down, and the pressing force of spring 15 on the chip is adjusted by adjusting screw 11" is relatively cumbersome. The limiting frame 9 is also prone to improper pressing, which can cause chip wear.

[0004] Therefore, a chip box that facilitates chip clamping is proposed. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a chip holder that facilitates chip clamping, thereby resolving the issues raised in the background section.

[0006] The technical solution of this utility model is:

[0007] A chip holder for easy chip handling includes a housing and an end cap. The end cap is fitted onto the top of the housing. The surface of the end cap has multiple equidistant guide openings. One side of each guide opening has an adjustment opening on the surface of the end cap. A limiting plate is inserted into the inner wall of the guide opening. The bottom end of the limiting plate is in contact with the bottom surface of the inner wall of the housing. Equidistant racks are fixedly connected to the surface of the limiting plate. A gear is rotatably connected to the inner wall of the adjustment opening. The gear meshes with the racks. A chip slot is formed on the surface of the limiting plate. A sealing plate is provided at the opening of the chip slot.

[0008] The working principle of the above technical solution is as follows:

[0009] Initially, the gear is located at the top of the limiting plate, and the sealing plate closes the opening of the chip slot. When a chip needs to be placed, first slide the gear to the surface of the rack, and then rotate the gear. Due to the meshing connection between the gear and the rack, the limiting plate moves upward from the inner wall of the guide opening in the end cover. When the limiting plate moves to a certain position, that is, when the top surface of the stop block contacts the bottom of the guide opening, the sealing plate is dragged down, and the slider slides on the inner wall of the slide until the chip slot unfolds. The slider is suspended at the bottom of the slide. At this time, chips of different thicknesses are placed in each exposed chip slot. After placement, reverse the gear, allowing the limiting plate to move down again under the meshing action of the gear and rack until the bottom of the limiting plate contacts the bottom surface of the inner wall of the box. During this process, the bottom of the sealing plate is simultaneously pushed, and the sealing plate resets and covers the opening of the chip slot again. The chip is stably limited inside the chip slot. When a chip needs to be removed individually, repeat the above action of rotating the gear to raise the limiting plate, exposing the chip slot, and the chip can be easily removed.

[0010] In a further technical solution, the side of the limiting plate away from the rack is a plane, one end of the rack is provided with a transition surface located on the surface of the limiting plate, and the intersection of the transition surface plane and the rack is an arc surface. The inner wall of the adjustment port is fixedly connected with symmetrically arranged connecting springs, and a rotating shaft is fixedly connected between the two connecting springs. The surface of the gear is provided with a sliding opening, and the sliding opening is sleeved on the surface of the rotating shaft.

[0011] With the above technical solution, when the gear is not in use, it can be moved to the plane of the limiting plate and placed against it, so that the gear has a fixed placement position and will not shake or be in a position that would cause misoperation.

[0012] In a further technical solution, slides are provided on both sides of the inner wall of the chip slot, and sliders are fixedly connected to both sides of the top of the sealing plate, and the bottom of the slides does not penetrate the chip slot.

[0013] Through the above technical solution, the cooperation between the slide and the slider enables the sealing plate to move along a fixed trajectory during the sliding process, avoiding deviation or jamming, thereby ensuring the accuracy and reliability of the seal. Since the bottom of the slide does not penetrate the chip slot, it can effectively prevent the slider from sliding out from the bottom of the slide, thereby preventing the sealing plate from falling off accidentally and ensuring that the chip slot can always be effectively sealed.

[0014] In a further technical solution, the side wall of the limiting plate and the inner wall of the guide port are both provided with magnetic suction grooves, and the gear is normally located on one side of the top of the limiting plate.

[0015] Through the above technical solution, the magnetic groove can keep the limiting plate in a more accurate position in the inner wall of the guide port, avoid unnecessary shaking and displacement in non-operational state, and ensure stable storage of the chip.

[0016] In a further technical solution, a locking block is fixedly connected to the inner wall of the end cap, and a slot for engaging with the locking block is opened on the surface of the box body.

[0017] Through the above technical solution, the engagement of the card block and the card slot can tightly connect the end cap and the box body, enhance the stability of the overall structure, and effectively prevent the end cap from accidentally falling off.

[0018] In a further technical solution, a stop block is fixedly connected to the bottom outer surface of the sealing plate.

[0019] With the above technical solution, when the sealing plate slides to a specific position, the contact between the stop block and the bottom surface of the guide port will produce a clear tactile sensation, allowing the operator to intuitively perceive that the sealing plate has reached its limit position, thereby better controlling the operation.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] By incorporating a limiting plate, rack, gears, and chip slots, the chip slots on the limiting plate surface provide dedicated space for the chip, ensuring sufficient room for the chip during storage and preventing direct contact with other components, thus reducing wear on the pressure surface. Furthermore, the meshing connection between the rack and gears allows the limiting plate to be raised and lowered flexibly. When placing or removing a chip, the limiting plate is raised to expose the chip slot; after the operation, the limiting plate is lowered, ensuring the chip remains in a stable and protected environment when not in operation. This structure protects the chip throughout the entire storage and handling process, reducing the risk of wear due to improper positioning and improving chip storage quality and lifespan.

[0035] Example:

[0036] Please see Figure 1-8 A chip box for easy chip handling includes a box body 1 and an end cap 2. The end cap 2 is fitted onto the top of the box body 1. The surface of the end cap 2 has multiple equidistant guide openings 3. One side of the guide opening 3 has an adjustment opening 4 on the surface of the end cap 2. A limiting plate 5 is inserted into the inner wall of the guide opening 3. The bottom end of the limiting plate 5 is in contact with the bottom surface of the inner wall of the box body 1. The surface of the limiting plate 5 is fixedly connected with equidistant racks 51. The inner wall of the adjustment opening 4 is rotatably connected with gears 8, which mesh with the racks 51. The surface of the limiting plate 5 has a chip groove 10. A sealing plate 11 is provided at the opening of the chip groove 10.

[0037] The working principle of the above technical solution is as follows:

[0038] In the initial state, gear 8 is located on the top side of the limiting plate 5, and sealing plate 11 closes the opening of chip slot 10. When a chip needs to be placed, gear 8 is first slid to the surface of rack 51, and then gear 8 is rotated. Since gear 8 and rack 51 are meshed, limiting plate 5 moves upward from the inner wall of guide opening 3 in end cover 2. When limiting plate 5 moves to a certain position, that is, when the top surface of stop 14 contacts the bottom of the opening of guide opening 3, sealing plate 11 is dragged down, and slider 13 slides on the inner wall of slide rail 12 until chip slot 10 unfolds and slider 13 is suspended at the bottom of slide rail 12. At this point, chips of different thicknesses are placed in each exposed chip slot 10. After placement, the gear 8 is reversed, causing the limiting plate 5 to move down again under the meshing action of the gear 8 and the rack 51 until the bottom end of the limiting plate 5 contacts the bottom surface of the inner wall of the box 1. During this process, the bottom end of the sealing plate 11 will be pushed up simultaneously, and the sealing plate 11 will reset and cover the opening of the chip slot 10 again. The chip is stably limited inside the chip slot 10. When it is necessary to remove the chip individually, the action of turning the upper gear 8 to raise the limiting plate 5 is repeated to expose the chip slot 10, and the chip can be easily removed.

[0039] Please see Figure 3 and Figure 4The side of the limit plate 5 away from the rack 51 is a plane. One end of the rack 51 is provided with a transition surface 9 located on the surface of the limit plate 5. The intersection of the plane of the transition surface 9 and the rack 51 is an arc surface. The inner wall of the adjustment port 4 is fixedly connected with symmetrically arranged connecting springs 6. A rotating shaft 7 is fixedly connected between the two connecting springs 6. The surface of the gear 8 is provided with a sliding opening 81, which is sleeved on the surface of the rotating shaft 7.

[0040] When gear 8 is not in use, it can be moved to the plane of the limiting plate 5 and placed against it, so that gear 8 has a fixed placement position and will not shake or be in a position that would cause misoperation.

[0041] Please see Figure 7 and Figure 8 The chip slot 10 has slides 12 on both sides of its inner wall, and sliders 13 are fixedly connected to both sides of the top of the sealing plate 11. The bottom of the slides 12 does not penetrate the chip slot 10.

[0042] The cooperation between the slide 12 and the slider 13 allows the sealing plate 11 to move along a fixed trajectory during the sliding process, avoiding deviation or jamming, thereby ensuring the accuracy and reliability of the seal. Since the bottom end of the slide 12 does not penetrate the chip slot 10, it can effectively prevent the slider 13 from sliding out from the bottom of the slide 12, thereby preventing the sealing plate 11 from accidentally falling off and ensuring that the chip slot 10 can always be effectively sealed.

[0043] The side wall of the limiting plate 5 and the inner wall of the guide port 3 are both provided with magnetic suction grooves, and the gear 8 is normally located on the top side of the limiting plate 5.

[0044] The magnetic groove design allows the limiting plate 5 to maintain a more accurate position within the inner wall of the guide port 3, preventing unnecessary shaking or displacement during non-operational states and ensuring stable chip storage.

[0045] Please see Figure 4 and Figure 5 The inner wall of the end cap 2 is fixedly connected with a locking block 15, and the surface of the box body 1 is provided with a locking groove 16 that engages with the locking block 15.

[0046] The engagement of the locking block 15 and the locking slot 16 enables the end cap 2 and the box body 1 to be tightly connected, enhancing the stability of the overall structure and effectively preventing the end cap 2 from accidentally falling off.

[0047] Please see Figure 6 and Figure 7 A stop 14 is fixedly connected to the bottom outer surface of the sealing plate 11.

[0048] When the sealing plate 11 slides to a specific position, the stop 14 will make contact with the bottom surface of the guide port 3, which will produce a clear tactile sensation, allowing the operator to intuitively perceive that the sealing plate 11 has reached its limit position, thereby better controlling the operation.

[0049] During operation, firstly, the gear 8 is slid onto the surface of the rack 51, and then the gear 8 is rotated, causing the rack 51 on the surface of the limiting plate 5 to mesh with the gear 8. This causes the limiting plate 5 to move upward from the inner wall of the guide opening 3. When the limiting plate 5 moves upward to the position where the top surface of the stop block 14 contacts the bottom of the opening of the guide opening 3, the sealing plate 11 is dragged down. Then, the slider 13 slides on the inner wall of the slide rail 12 until the chip slot 10 unfolds and the slider 13 is suspended at the bottom end of the slide rail 12. At this point, chips of different thicknesses are placed into each of the exposed chip slots 10. Then, the gear 8 is reversed, causing the limiting plate 5 to move downward again due to the meshing of the gear 8 and the rack 51, until the bottom end of the limiting plate 5 contacts the bottom surface of the inner wall of the housing 1. During this process, the bottom end of the sealing plate 11 is also pushed up simultaneously, and then the sealing plate 11 resets and covers the chip slot 10. At the opening, the chip is placed inside the chip slot 10 and is limited. When the chip needs to be removed individually, the gear 8 is turned, and the action of raising the upper limit plate 5 is repeated. Since the chip can be placed inside the chip slot 10 throughout the process, there is enough space to store and limit it, and it will not be affected by the wear of the pressure surface. At the same time, the device is also convenient to pick up and put down. After the gear 8 is used, the gear 8 can be pushed on the surface of the rotating shaft 7. Since one side of the transition surface 9 is a curved surface, the gear 8 can be pushed on the plane of the limit plate 5 and placed still. During the process, the gear 8 will move from the position of the rack 51 to the plane, and the teeth of the gear 8 will move in contact with the curved surface. At the same time, the rotating shaft 7 will be displaced under the support of the connecting spring 6. When the gear 8 needs to be rotated, the gear 8 can be slid on the surface of the rotating shaft 7 again, and the rotating shaft 7 will also be displaced.

[0050] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
