Abstract
Description
Technical Field
[0001] This utility model relates to the field of silicon wafer transfer technology, and in particular to a toothless pressure bar and a carrier basket structure. Background Technology
[0002] In the process of silicon wafer manufacturing, silicon wafers are usually transported by placing them on baskets. A basket is a structure used to place silicon wafers. When silicon wafers are placed vertically on a basket, pressure bars are set on the basket to ensure the stability of the silicon wafers during transportation. At the same time, in order to better separate the silicon wafers, pressure bars are usually also equipped with the same number of pressure bar teeth as the spacing teeth on the basket.
[0003] After the silicon wafers are placed in the basket, the pressure bar teeth need to be rotated from a horizontal to a vertical position so that the silicon wafers are spaced apart at the top. However, in actual operation, when rotating the pressure bar, there is a certain probability that the pressure bar teeth will come into contact with the silicon wafers, which may cause the silicon wafers to break or chip. Utility Model Content
[0004] The purpose of this invention is to provide a toothless pressure bar and a basket-carrying structure to address the above-mentioned shortcomings. This solves the problem in the prior art where, during the rotation of the pressure bar, the pressure bar teeth may come into contact with the silicon wafer, causing the silicon wafer to break or chip.
[0005] This utility model is achieved through the following solution:
[0006] A toothless pressure bar includes, but is not limited to, a bar body, a retaining ring, a limiting part, and a retaining tongue; the retaining ring is symmetrically arranged at both ends of the bar body, the retaining ring is connected to the limiting part, the limiting part is connected to the retaining tongue, and the sidewall of the bar body is smoothly formed.
[0007] Based on the above-mentioned toothless pressure bar structure, the retaining ring portion is collinear with the center of the rod body portion, and the retaining ring portion is provided to protrude from the side wall of the rod body portion.
[0008] Based on the above-mentioned toothless pressure bar structure, the limiting part includes a first limiting arc and a second limiting arc. The size of the first limiting arc is not less than the size of the second limiting arc, and the connection between the first limiting arc and the second limiting arc is arc-shaped, forming a lock hole structure with one end larger than the other.
[0009] Based on the above-mentioned toothless pressure bar structure, the line connecting the farthest end of the first limiting arc and the farthest end of the second limiting arc is on a straight line, and the distance between the line connecting the farthest end of the first limiting arc and the farthest end of the second limiting arc is not less than the distance at the maximum size of the first limiting arc.
[0010] Based on the above-mentioned toothless pressure bar structure, the contours of the locking hole structure formed by the first limiting arc and the second limiting arc do not exceed the contours of the retaining ring.
[0011] 6. A structure for transporting flower baskets, characterized in that: it includes a flower basket sidewall, a toothed pressure rod and a toothless pressure rod, wherein a limiting hole is provided on the flower basket sidewall, and the toothless pressure rod can be inserted into the limiting hole by rotation.
[0012] Based on the above-mentioned structure for transporting flower baskets, the limiting hole includes an outward expansion groove and a receiving groove; the receiving groove is provided with an opening, the opening is connected to the outward expansion groove, the shape of the receiving groove is the same as the outline of the first limiting arc, the size of the receiving groove is not less than the size of the first limiting arc; the size of the opening of the receiving groove is less than the distance value at the line connecting the farthest end of the first limiting arc and the farthest end of the second limiting arc.
[0013] Based on the above-mentioned flower basket structure, the latch is located at the end of the limiting part, and the outer contour of the latch is within the range of the end face of the limiting part, so that the latch and the limiting part form a stepped structure.
[0014] Based on the above-mentioned structure for transporting flower baskets, the cross-sectional structure of the tongue is a rectangular, square, triangular, or oblong hole-shaped structure.
[0015] Based on the above-mentioned flower basket structure, the limiting part is made of flexible plastic material, and the toothed pressure rod is provided with spacer teeth for spacing silicon wafers.
[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0017] 1. In use, this solution uses an external mechanical structure to press the toothless pressure rod into a predetermined position on the basket. The locking tongue cooperates with the rotating structure to rotate the entire toothless pressure rod, ultimately locking the entire limiting part into the slot of the basket, thus fixing the toothless pressure rod. Because the rod body of the toothless pressure rod is smoothly designed, it will not interfere with the silicon wafer at its bottom when it is rotated. At the same time, it can restrict the top of the silicon wafer when it is locked in place, preventing the silicon wafer from detaching from the top. This avoids the situation in the prior art where the silicon wafer is damaged due to the rotation of the pressure rod teeth, thus improving the safety of silicon wafer transportation.

[0027] Example 1
[0028] like Figures 1-2 As shown, this utility model provides a technical solution:
[0029] A toothless pressure bar includes, but is not limited to, a bar body 1, a retaining ring 2, a limiting part 3, and a retaining tongue 4; the retaining ring 2 is symmetrically arranged at both ends of the bar body 1, the retaining ring 2 is connected to the limiting part 3, the limiting part 3 is connected to the retaining tongue 4, and the side wall of the bar body 1 is smoothly arranged.
[0030] Based on the above structure, during use, the toothless pressure rod 11 is pressed into a predetermined position on the flower basket by an external mechanical structure. The entire toothless pressure rod 11 is rotated by the cooperation of the latch 4 and the rotating structure, and finally the entire limiting part 3 is locked into the slot of the flower basket, thus fixing the toothless pressure rod 11. Since the rod body 1 of the toothless pressure rod 11 is smoothly designed, it will not interfere with the silicon wafer at its bottom when it is rotated. At the same time, it can restrict the top of the silicon wafer when it is locked and fixed, preventing the silicon wafer from falling off from the top. This avoids the situation in the prior art where the silicon wafer is damaged due to the rotation of the pressure rod teeth, and improves the safety of silicon wafer transportation.
[0031] As an example, the retaining ring 2 is collinear with the center of the rod body 1, and the retaining ring 2 is provided to protrude from the side wall of the rod body 1, so that the ends of the retaining ring 2 and the rod body 1 are evenly spaced.
[0032] Based on the above structure, the retaining ring 2 can effectively isolate the rod body 1 and the limiting part 3. When the retaining ring 2 is transported to the top slot of the basket, the retaining ring 2 located at both ends of the rod body 1 can play a certain axial limiting role, so that the rod body 1 can only be restricted to the area where the silicon wafer is located and cannot be detached, thus ensuring the safety of subsequent processes.
[0033] As an example, the limiting part 3 may include a first limiting arc 5 and a second limiting arc 6. The size of the first limiting arc 5 is not smaller than the size of the second limiting arc 6, and the connection between the first limiting arc 5 and the second limiting arc 6 is arc-shaped, forming a lock hole structure with one end larger than the other.
[0034] The line connecting the farthest end 7 of the first limiting arc and the farthest end 8 of the second limiting arc is on a straight line, and the distance between the line connecting the farthest end 7 of the first limiting arc and the farthest end 8 of the second limiting arc is not less than the distance at the maximum size of the first limiting arc 5.
[0035] Based on the above structure, the limiting part 3 is set to a structure with one large and one small. When the first limiting arc 5 and the second limiting arc 6 are kept vertical, the first limiting arc 5 is at its maximum size. When the limiting part 3 is rotated to a horizontal position, the maximum size is at the line connecting the farthest end 7 of the first limiting arc and the farthest end 8 of the second limiting arc. That is, the shape of the limiting part 3 can be changed by rotation, so that it can be locked or released in the fixed hole.
[0036] As an example, the outline of the lock hole structure formed by the first limiting arc 5 and the second limiting arc 6 does not exceed the outline of the retaining ring portion 2. This ensures that the entire lock hole structure is within a specified range.
[0037] As an example, the latch 4 is provided at the end of the limiting part 3, and the outer contour of the latch 4 is within the range of the end face of the limiting part 3, so that the latch 4 and the limiting part 3 form a stepped structure, which facilitates positioning by the external rotating structure.
[0038] As an example, the cross-sectional structure of the latch 4 can be rectangular, square, triangular, or oblong.
[0039] Example 2
[0040] Based on the above embodiment 1, as Figures 3-4 As shown, this utility model provides a technical solution:
[0041] A flower basket transport structure includes a flower basket side wall 9, toothed pressure rods 10 and toothless pressure rods 11. Multiple toothed pressure rods 10 are arranged between the flower basket side walls 9. A limiting hole is provided at the top position of the flower basket side wall 9 to cooperate with the end of the toothless pressure rod 11. The limiting part 3 of the toothless pressure rod 11 can be inserted into the limiting hole by rotation.
[0042] Based on the above structure, silicon wafers can be placed in the frame structure formed by the basket sidewall 9 and the toothed pressure bar 10. After the silicon wafers are filled, the limiting part 3 of the toothless pressure bar 11 is pressed into the limiting hole to fix all the silicon wafers, which improves the safety during transportation. At the same time, since the surface of the toothless pressure bar 11 is smooth, its surface will not cause damage to the silicon wafers when it is rotated and fixed.
[0043] As an example, the limiting hole may include an outer expansion groove 12 and a receiving groove 13; the receiving groove 13 is provided with an opening, which is connected to the outer expansion groove 12, the shape of the receiving groove 13 is the same as the outline of the first limiting arc 5, and the size of the receiving groove 13 is not less than the size of the first limiting arc 5.
[0044] The size of the opening of the receiving groove 13 is smaller than the distance at the line connecting the farthest end 7 of the first limiting arc and the farthest end 8 of the second limiting arc.
[0045] Based on the above structure, when the locking hole structure formed by the limiting part 3 is in the vertical state, it can be driven into the receiving groove 13. Then, by rotating, the limiting part 3 becomes horizontal. At this time, since the opening size of the receiving groove 13 is smaller than the distance between the farthest end 7 of the first limiting arc and the farthest end 8 of the second limiting arc, the limiting part 3 is restricted from disengaging from the opening, thus fixing the toothless pressure rod 11.
[0046] As an example, the limiting part 3 is made of flexible plastic material. Using flexible material can increase the friction with the limiting hole and avoid damage to the side wall 9 of the basket.
[0047] As an example, the toothed pressure bar 10 may be provided with spacer teeth for spacing silicon wafers.
[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
