Description

Technical Field

[0001] This utility model relates to the field of silicon wafer production technology, and in particular to a basket-turning auxiliary tool. Background Technology

[0002] Silicon wafer baskets are crucial carriers in diode manufacturing. In actual production, silicon wafers are placed into baskets, which then enter the equipment for processing. Existing baskets are equipped with alignment holes and pins for positioning by the equipment. When these alignment holes and pins wear out, the baskets need to be replaced promptly, transferring the silicon wafers to new baskets before continuing production. Currently, a manual basket-turning method is mainly used. A new basket is manually placed on top of the old one, and then the two baskets are inverted to transfer the wafers. This method relies heavily on the operator's experience; inexperienced operators are prone to dropping the wafers, causing them to be scrapped. Utility Model Content

[0003] To address the shortcomings of existing basket rotation methods that easily lead to wafer breakage and waste, this invention proposes a basket rotation auxiliary tool to improve basket rotation stability and ensure wafer safety.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A basket-turning auxiliary tool includes a housing and a basket-pressing assembly. The housing has an open upper side and can accommodate two baskets. Two basket-pressing assemblies are provided and installed on one side of the housing to lock the two baskets in the housing. The basket-pressing assembly includes a pressure plate, an elastic telescopic rod, a slider, and a first spring. A guide hole is provided on one side of the housing. The elastic telescopic rod passes vertically through the guide hole and is slidably connected to the guide hole. The inner end of the elastic telescopic rod is fixedly connected to the pressure plate to squeeze the baskets. A first serration is provided on one side of the elastic telescopic rod. The slider is slidably connected to the outside of the housing. The slider is provided with a second serration that matches the first serration. The first spring is installed on one side of the slider. The slider engages with the elastic telescopic rod through the first serration and the second serration.

[0005] With the above settings, firstly, two pressure basket components are used to lock the two baskets together, ensuring that the baskets will not come apart after being locked, thus guaranteeing the stability of the baskets and the silicon wafers and preventing the silicon wafers from falling and smashing, which could lead to scrapping accidents. Secondly, a direct-push locking method is used to lock the baskets, making locking and releasing the baskets faster and improving basket rotation efficiency.

[0006] Furthermore, the elastic telescopic rod includes a sleeve, a connecting rod, and a second spring. The sleeve passes through a guide hole and is slidably connected to the guide hole. A first serration is provided on one side of the sleeve. A slot is provided at the inner end of the sleeve. One end of the connecting rod is slidably connected to the slot, and the other end of the connecting rod is fixedly connected to the aforementioned pressure plate. The second spring is installed in the slot and is connected to the end of the connecting rod.

[0007] Furthermore, the upper and lower sides of the sleeve are provided with limiting grooves along the length direction, and the hole wall of the guide hole fits into the groove wall of the limiting groove on the upper and lower sides.

[0008] With the above settings, the sleeve moves more stably in the axial direction.

[0009] Furthermore, the slider is a rectangular structure surrounding the sleeve, the second serration is set inside the slider, and a groove is provided on the lower side of the slider. The auxiliary tool also includes a pull rod, which is slidably connected to the outside of the housing. A push block is fixedly connected to the upper side of the pull rod, and the push block extends into the groove. The width of the push block is smaller than the width of the groove.

[0010] The above settings facilitate the release of the flower basket by the pressure basket assembly.

[0011] Furthermore, the auxiliary tools also include a handle that is fixedly connected to one end of the housing.

[0012] The above-described design facilitates the rotation of the housing.

[0013] Furthermore, one end of the handle is provided with a clearance groove, one end of the lever extends into the clearance groove and is fixedly connected to a lever, which passes through the clearance groove and extends into the inside of the handle.

[0014] The above settings allow for easy lifting of the lever to quickly release the flower basket, further improving basket rotation efficiency. Attached Figure Description

[0021] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0022] like Figures 1 to 6 A basket-turning auxiliary tool includes a housing 3 and a basket-pressing assembly. The upper side of the housing 3 is open, and the interior can accommodate two baskets 4. Two basket-pressing assemblies are provided and installed on one side of the housing 3 to lock the two baskets 4 in the housing 3. The basket-pressing assembly includes a pressure plate 5, an elastic telescopic rod 6, a slider 7 and a first spring 8. A guide hole 9 is provided on one side of the housing 3. The elastic telescopic rod 6 passes vertically through the guide hole 9 through one side of the housing 3 and is slidably connected to the guide hole 9. The inner end of the elastic telescopic rod 6 is fixedly connected to the pressure plate 5 so as to squeeze the baskets 4. A first serration 10 is provided on one side of the elastic telescopic rod 6. The slider 7 is slidably connected to the outside of the housing 3. The slider 7 is provided with a second serration 11 adapted to the first serration 10. The first spring 8 is installed on one side of the slider 7. The slider 7 engages with the elastic telescopic rod 6 through the first serration 10 and the second serration 11.

[0023] With the above settings, firstly, two pressure basket components are used to lock the two flower baskets 4. Once the two flower baskets 4 are locked together, they will not come apart, ensuring the stability of the flower baskets 4 and the silicon wafer and preventing the silicon wafer from falling and smashing, which could lead to scrapping accidents. Secondly, a direct push locking method is used to lock the flower baskets 4, which makes locking and releasing the flower baskets 4 faster and improves the efficiency of basket rotation.

[0024] Figure 1 The auxiliary tool for marking the front, back, left, and right sides, in this application, the housing 3 specifically includes a back plate 31, side plates 32, and an end plate 33. The back plate 31 is horizontally arranged. Two side plates 32 are provided, parallel to each other, and vertically fixedly connected to the left and right sides of the back plate 31. The end plate 33 is located between the two side plates 32 and vertically fixedly connected to the rear end of the back plate 31. The end plate 33, side plates 32, and back plate 31 form a receiving groove for accommodating two flower baskets 4. Two basket pressing assemblies are arranged on one of the side plates 32. The pressure basket assembly is arranged front and back to lock the two baskets 4. The pressure plate 5 is parallel to the side plate 32. The elastic telescopic rod 6 is a rod-shaped structure with an axially extendable inner end. When rotating the basket, the new basket 4 is placed in the housing 3, with the bottom of the new basket 4 abutting against the end plate 33. The basket 4 to be replaced is already loaded with silicon wafers. The old basket 4 is placed into the housing 3, with the silicon wafers in the old basket 4 aligned with the new basket 4. The bottom of the old basket 4 faces away from the new basket 4, and the old basket 4 is close to the new basket 4. The two baskets 4 abut against each other. Figure 5At this point, the two flower baskets 4 are in a flat position. Pushing the slider 7 releases the slider 7 from the elastic telescopic rod 6. Pushing the elastic telescopic rod 6 causes the pressure plate 5 at the inner end of the elastic telescopic rod 6 to press the flower baskets 4. Under the action of the first spring 8, the slider 7 engages with the elastic telescopic rod 6 through the first sawtooth 10 and the second sawtooth 11, preventing the elastic telescopic rod 6 from retracting and releasing the flower baskets 4. Thus, the two flower baskets 4 are locked. Rotating the housing 3 causes the end plate 33 of the housing 3 to face downwards, and the two flower baskets 4 are positioned vertically. Figure 6 The new basket 4 is located below the old basket 4. The lower basket 4 carries the silicon wafer. Pushing the slider 7 releases the slider 7 from the elastic telescopic rod 6. The pressure plate 5 at the end of the elastic telescopic rod 6 releases the basket 4, allowing the old basket 4 to be removed from the housing 3. The silicon wafer is now in the new basket 4, completing the basket rotation. The entire basket rotation process basically does not contact the silicon wafer, preventing contamination. Furthermore, the direct-push basket 4 locking method allows for faster locking and releasing of the basket 4, improving basket rotation efficiency and adapting to various sizes of baskets 4.

[0025] As one implementation, the elastic telescopic rod 6 includes a sleeve 61, a connecting rod 62, and a second spring 63. The sleeve 61 passes through the guide hole 9 and is slidably connected to the guide hole 9. The first serration 10 is provided on one side of the sleeve 61. A slot is provided at the inner end of the sleeve 61. One end of the connecting rod 62 is slidably connected to the slot. The other end of the connecting rod 62 is fixedly connected to the pressure plate 5. The second spring 63 is installed in the slot and is connected to the end of the connecting rod 62.

[0026] The sleeve 61 of this application has a basically square cross-section. The sleeve 61 penetrates the guide hole 9 vertically, and the guide hole 9 plays a stable guiding role. The sleeve 61 can only move axially. The first sawtooth 10 is specifically set on the side of the sleeve 61 facing away from the end plate 33. After the second sawtooth 11 of the slider 7 engages with the first sawtooth 10, the slider 7 locks the sleeve 61, and the sleeve 61 cannot move axially. The connecting rod 62 can move axially in the slot. When the sleeve 61 moves toward the basket 4, the pressure plate 5 presses against the basket 4, and the connecting rod 62 moves into the slot, squeezing the second spring 63. The second spring 63 is compressed and provides a thrust to the pressure plate 5 through the connecting rod 62 to press the basket 4 onto another side plate 32 to complete the locking of the basket 4.

[0027] As one implementation method, the upper and lower sides of the sleeve 61 are provided with limiting grooves 12 along the length direction, and the hole wall of the guide hole 9 fits into the groove wall of the limiting grooves 12 on the upper and lower sides.

[0028] With the above settings, the sleeve 61 is more stable during axial movement.

[0029] The sleeve 61 of this application is provided with limiting grooves 12 on both the upper and lower sides. The cross-section of the sleeve 61 is basically I-shaped. The upper and lower side walls of the guide hole 9 are fitted with the limiting grooves 12 to prevent the sleeve 61 from moving up, down, left, and right, so that the sleeve 61 can only move axially and stably.

[0030] As one implementation, the slider 7 is a rectangular structure surrounding the sleeve 61. The second serration 11 is set inside the slider 7. The lower side of the slider 7 is provided with a groove 13. The auxiliary tool also includes a pull rod 14, which is slidably connected to the outside of the housing 3. A push block 15 is fixedly connected to the upper side of the pull rod 14. The push block 15 extends into the groove 13, and the width of the push block 15 is smaller than the width of the groove 13.

[0031] The above settings facilitate the release of the flower basket 4 from the pressure basket assembly.

[0032] In this application, the slider 7 and the pull rod 14 can only move back and forth outside the side plate 32. When it is necessary to release the flower basket 4, the pull rod 14 is pulled forward, and the pull rod 14 drives the push block 15 to move forward. The push block 15 abuts against the front side wall of the groove 13 and pushes the slider 7 to move forward and disengage from the sleeve 61. After the sleeve 61 moves, the pressure plate 5 releases the flower basket 4.

[0033] As one implementation method, the auxiliary tool also includes a handle 16 fixedly connected to one end of the housing 3.

[0034] The above settings facilitate the rotation of housing 3.

[0035] The handle 16 of this application is specifically set at the front end of the housing 3. The two ends of the handle 16 are fixedly connected to the left and right side plates 32 respectively. After the two flower baskets 4 are put into the housing 3 and locked, the handle 16 is lifted upwards, that is, the housing 3 can be stood up.

[0036] As one implementation, one end of the handle 16 is provided with a relief groove 17, one end of the pull rod 14 extends to the relief groove 17 and is fixedly connected with a lever 18, which passes through the relief groove 17 and extends to the inside of the handle 16.

[0037] The above settings allow for easy lifting of lever 14 via lever 18 to quickly release basket 4, further improving basket rotation efficiency.

[0038] like Figure 6 After lifting the handle 16 to stand the housing 3 upright, press the lever 18 with your finger. The lever 18 drives the pull rod 14 to move upward. The pull rod 14 pushes the slider 7 upward through the push block 15. After the slider 7 disengages from the sleeve 61, the flower basket 4 is quickly released, making it easy to remove the flower basket 4 from the housing 3.

[0039] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
