[0034] The utility model aims to provide a crystal rod hoisting fixture to solve the problem that the existing hoisting tools need to manually operate the hook and the hanging rod, which reduces the work efficiency and cannot ensure the safety performance.
[0035] It can be understood by those skilled in the art that in the semiconductor manufacturing process, after the crystal rod is cut, it needs to be hoisted and transported during the processing flow. At present, the industry mostly uses manual handling or sling binding hoisting, which has high operation requirements and great safety hazards, especially the 12-inch crystal rod is large and heavy, and it is easy to cause accidents to damage the product or personnel. At the same time, there is a crystal rod clamp in the prior art, which requires manual operation to connect or disconnect the hook and the hanging rod, which is time-consuming and labor-intensive, and reduces the efficiency of hoisting the crystal rod. Based on this, the present application provides a crystal rod hoisting clamp, which can realize the automatic clamping and placing function through the mutual cooperation of the limit piece and the limit block, reduce the labor input, and improve the efficiency of crystal rod hoisting.

It should be noted that Figure 1 For example, the driving assembly includes two driving arms 2, one end of the two driving arms 2 is connected to each other, and the other end is connected to two clamping arms 1 respectively, so as to drive the clamping arms 1 to open or close; wherein the two driving arms 2 are respectively hinged to the two clamping arms 1, and the lifting force of the driving arms 2 is converted into the clamping force of the clamping arms 1 through the lever principle; the limiter 3 can rotate around the axis to slide in the limiter block 4. The crystal rod lifting fixture can also include a hook 6 and a handle 7, wherein the hook 6 is connected to the driving arm 2, and is used to hang the entire crystal rod lifting fixture on a crane or a lifting vehicle to realize the transportation of the crystal rod 8; there are two handles 7, which are respectively arranged on the sides of the two clamping arms 1 facing the outside, and are used to control the working position of the fixture. In other embodiments, the crystal rod lifting fixture can also include some other components to facilitate the clamping and transportation of the crystal rod 8, which is not limited in this embodiment.
[0037] With such configuration, by setting a limit member 3 on the driving component and a limit block 4 on the clamping arm 1, in the process of the driving component driving the clamping arm 1 to open or close, the limit member 3 can slide into or out of the limit block 4 along a predetermined trajectory, thereby limiting or releasing the restriction on the opening degree of the clamping arm 1. Compared with the prior art which requires manual operation by an operator, the crystal rod lifting clamp in the present application can control the opening degree of the clamping arm 1 by sliding the limit member 3 in the limit block 4 without manual operation, thereby improving work efficiency and avoiding unnecessary damage caused by manual operation, thereby further improving the yield of the product.
[0038] As an alternative embodiment, please refer to Figures 3 to 5 , a protrusion 31 is provided at one end of the limit member 3 sliding into the limit block 4, a protrusion 41 is provided in the limit block 4, and the protrusion 31 engages with the protrusion 41 to limit the opening degree of the clamping arm 1. It should be noted that in this embodiment, the limit member 3 is provided with a protrusion 31, which is a cylindrical component, and the limit block 4 is provided with a protrusion 41, which is a polygonal component, and its side wall has a certain length, which can be contacted with the protrusion 31 after the protrusion 31 slides into the limit block 4 to achieve the limit of the opening degree of the clamping arm 1; when the crystal rod 8 is transported to the target position or the crystal rod 8 needs to be adjusted, it is only necessary to lower the suspended crystal rod 8 to the plane, and the vibration generated between the crystal rod 8 and the plane can make the protrusion 31 detach from the protrusion 41 and slide out of the limit block 4, thereby releasing the restriction on the opening degree of the clamping arm 1.
[0039] Further, such as Figure 4 and Figure 5 As shown, the predetermined track is the track formed by the limiter 3 sliding along the predetermined track, and the predetermined track includes a slide-in track and a slide-out track; the limiter 3 can slide into the limiter block 4 along the slide-in track, and the protrusion 31 engages with the protrusion 41 to limit the opening degree of the clamping arm 1; the limiter 3 can slide out of the limiter block 4 along the slide-out track, and the protrusion 31 is released from the protrusion 41 to release the restriction on the opening degree of the clamping arm 1. In this embodiment, by providing a groove and a slope in the limiter block 4, the protrusion 31 that slides in is guided to engage or release with the protrusion 41, thereby realizing the automatic clamping and release of the clamping arm 1. Of course, in other embodiments, a slide groove and an inclined wall can also be provided in the limiter block 4 to guide the protrusion 31, and those skilled in the art can configure this according to actual conditions, and this embodiment does not limit this.
[0040] In an alternative embodiment, the slide-in rail includes a first slide groove 42, a second slide groove 43 and a third slide groove 44, the first slide groove 42 is arranged on one side of the protrusion 41, the first slide groove 42 is connected to the second slide groove 43, the second slide groove 43 is connected to the third slide groove 44, the third slide groove 44 is connected to the side wall of the protrusion 41, and the limit member 3 can slide from the first slide groove 42 into the limit block 4, and engage with the protrusion 41 when sliding into the third slide groove 44 through the second slide groove 43. Further, the first slide groove 42 includes a first section 421 and a second section 422, one end of the first section 421 is connected to the outside of the limit block 4, and the other end is connected to the second section 422, the second section 422 is connected to the second slide groove 43, and the second section 422 is inclined downward toward the second slide groove 43. Furthermore, the second slide groove 43 is inclined downward toward the third slide groove 44. It should be noted that in Figures 4 to 5 In the illustrated example, one end of the first slide groove 42 is connected to the outside of the limit block 4 and is located at a position corresponding to the limit member 3 on the driving arm 2, so that the limit member 3 can slide into the limit block 4 when the driving arm 2 and the clamping arm 1 approach each other; the first slide groove 42 is arranged on one side of the protrusion 41, and the protrusion 31 slides to the bottom of the protrusion 41 through the first slide groove 42, and moves toward the direction close to the protrusion 41 through the second slide groove 43, and finally the protrusion 31 and the protrusion 41 are engaged with the protrusion 41 at the position where the protrusion 41 is connected to the third slide groove 44.
[0041] As a preferred embodiment, the driving arm 2 needs to move in a direction close to the clamping arm 1 (in Figure 5 The first slide groove 42 is provided with a first section 421 and a second section 422. The first section 421 is the part for the protrusion 31 to slide into the limit block 4, and the second section 422 is connected to the second slide groove 43. The second section 422 can be set to a slope shape, and the second section 422 is inclined downward in the direction of the second slide groove 43. As long as the lowest point of the second section 422 is not lower than the highest point of the second slide groove 43, the lowest point of the second section 422 can be equal to the highest point of the second slide groove 43, or higher than the highest point of the second slide groove 43, which ensures that the protrusion 31 can slide smoothly into the second slide groove 43 after sliding into the second section 422 via the first section 421. At the same time, the second slide groove 43 can be set to be sloped and inclined downward toward the third slide groove 44. The lowest point of the second slide groove 43 should be higher than the highest point of the third slide groove 44, ensuring that the protrusion 31 can smoothly slide into the third slide groove 44 after sliding into the second slide groove 43. After entering the third slide groove 44, since the lowest point of the second slide groove 43 is higher than the highest point of the third slide groove 44, and the connection part between the side wall of the protrusion 41 and the third slide groove 44 is along Figure 5 The protrusion 31 is extended in the left and right directions, and at the same time, the protrusion 31 is pulled upward by the driving arm 2 (along Figure 5The protrusion 31 is arranged in the up and down direction in the middle), so the protrusion 31 will be stuck in the connection part between the third sliding groove 44 and the protrusion 41, thereby limiting the opening degree of the clamping arm 1.
[0042] In another optional embodiment, the slide-out track includes a third slide groove 44 and a fourth slide groove 45, the third slide groove 44 is connected to the fourth slide groove 45, the fourth slide groove 45 is connected to the first slide groove 42, and the stopper 3 can slide away from the protrusion 41 from the third slide groove 44, slide into the first slide groove 42 through the fourth slide groove 45, and slide out of the stopper 4. Further, the third slide groove 44 is inclined downward toward the fourth slide groove 45. It should be noted that Figure 4 and Figure 5 Taking the demonstration example shown as an example, when the protrusion 31 extends into the limit block 4 and engages with the protrusion 41, the clamping arm 1 remains open. At this time, the opening degree of the clamping arm 1 is adapted to the size of the crystal rod 8, which can ensure the stability of the crystal rod 8 during transportation and avoid unnecessary damage caused by manual operation; when the crystal rod 8 reaches the target position or the position of the crystal rod 8 needs to be adjusted, the crystal rod 8 will vibrate slightly when it is lowered to the plane. At this time, the protrusion 31 will be disengaged from the protrusion 41 and slide into the fourth slide groove 45, and finally slide out of the limit block 4 through the first section 421 of the first slide groove 42.
[0043] In a preferred embodiment, the third slide groove 44 is inclined downward toward the fourth slide groove 45. As long as the lowest point of the third slide groove 44 is not lower than the highest point of the fourth slide groove 45, the lowest point of the third slide groove 44 can be equal to the highest point of the fourth slide groove 45, or higher than the highest point of the fourth slide groove 45, ensuring that the protrusion 31 can smoothly slide into the fourth slide groove 45 after releasing the engagement with the protrusion 41. The fourth slide groove 45 is connected to the first section 421 of the first slide groove 42. Since the fourth slide groove 45 and most of the first slide groove 42 are along Figure 5 When the clamping arm 1 is released from restriction, the driving arm 2 moves in a direction away from the clamping arm 1. At this time, the protrusion 31 is pulled upward by the driving arm 2, so that the protrusion 31 slides out of the limit block 4, thereby releasing the restriction on the opening degree of the clamping arm 1.
[0044] In an optional embodiment, a plurality of buffer portions 5 are provided on the side wall where the clamping arm 1 contacts the crystal rod 8, and the buffer portions 5 contact the crystal rod 8 when the clamping arm 1 clamps the crystal rod 8. It should be noted that the buffer portions 5 may be elastic plastic plates, which contact the crystal rod 8 when the clamping arm 1 clamps the crystal rod 8, and protect the crystal rod 8 by using their own elasticity to avoid unnecessary damage to the crystal rod 8 during transportation. Figure 1In the illustrated example, four buffer portions 5 are provided, respectively disposed on the side walls where the clamping arm 1 contacts the crystal rod 8. In other embodiments, only two buffer portions 5 may be provided, or six, eight or even more buffer portions 5 may be provided. The buffer portion 5 may also be provided as a layered structure, completely covering the side walls where the clamping arm 1 contacts the crystal rod 8. Those skilled in the art may configure this according to actual conditions, and this embodiment does not impose any limitation on this.
