DETAILED DESCRIPTION

[0031] In order to make the technical problems to be solved, technical solutions and advantages of the present invention more clear, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0032] like Figure 1-5 As shown, an embodiment of the utility model provides a carrier for plasma cleaning, comprising a support body 1 and a clamping portion 2, wherein the support body 1 is a telescopic rod or a non-retractable rod. The clamping portions 2 are arranged at intervals in the axial direction of the support body 1, and the distance between the two clamping portions 2 can be adjusted. The clamping portion 2 includes a clamping arm 21, which is arranged in the circumferential direction of the support body 1, and the clamping arms 21 of the two clamping portions 2 overlap in projection in the circumferential direction of the support body 1, forming a relative relationship, and are respectively used to clamp the upper end and the lower end of the material.

[0033] In the present application, there are three ways to adjust the distance between the two clamping parts 2. The first way is: the support body 1 is a telescopic rod, and the two clamping parts 2 are respectively fixed at the two ends of the telescopic rod, and the distance between the two clamping parts 2 is adjusted by extending or shortening the two telescopic rods. The second way is: the support body 1 is a non-telescopic rod, at least one clamping part 2 is slidably set on the non-telescopic rod and can be fixed on the non-telescopic rod, and the distance between the two clamping parts 2 is adjusted by adjusting the position of at least one clamping part 2. The third way is: the support body 1 is a telescopic rod, and the two clamping parts 2 are respectively slidably set on the telescopic rod and can be fixed on the telescopic rod, and the distance between the two clamping parts 2 is adjusted by adjusting the position of at least one clamping part 2 and extending and retracting the telescopic rod.

[0034] In the present application, the clamping arms 21 of the two clamping parts 2 clamp the material respectively, and the two clamping parts 2 are arranged along the axial direction of the support body 1, so that the area covered by the material is reduced and can be fully exposed to the plasma environment. Compared with conventional cleaning, the carrier provided in the present application can minimize the cleaning dead corners.

[0035] In addition, the distance between the two clamping parts 2 in the present application can be adjusted, which can fully adapt to materials of different specifications.

[0036] The clamping portion 2 also includes a first ring 22, which is sleeved on the support body 1 and can move along the axial direction of the support body 1. The aforementioned clamping arm 21 is arranged on the circumference of the first ring 22 and is connected to the first ring 22. A first positioning assembly (not shown in the figure) is also arranged on the first ring 22, and the first positioning assembly is used to limit the axial position of the first ring 22 on the support body 1.

[0037] The clamping part 2 can slide and be fixed in the axial direction of the support body 1 by means of the first collar 22 and the first positioning assembly, thereby adjusting the distance between the two clamping parts 2 and fixing the distance.

[0038] In one embodiment of the present application, at least one clamping arm 21 is provided in each clamping portion 2, the first collar 22 is fixedly connected to the proximal end of the clamping arm 21, and the clamping arm 21 is provided in the radial direction of the first collar 22. Preferably, the angle between the clamping arm 21 and the supporting body 1 is a right angle.

[0039] Reference Figure 2-4 In another embodiment of the present application, at least one clamping arm 21 is provided in each clamping portion 2, and the proximal ends of the plurality of clamping arms 21 are hinged to the first ring 22. The clamping portion 2 also includes a locking assembly 23, which is used to maintain a constant angle between the clamping arm 21 and the supporting body 1.

[0040] like Figure 2and 3 In this embodiment, a structure of a locking assembly 23 is provided. The locking assembly 23 includes a locking bolt 231 and a nut 232. Specifically, a plurality of first hinged ears 221 are arranged on the circumference of the first collar 22. The locking bolt 231 is passed through the proximal end of the clamping arm 21 and the first hinged ear 221, so that the clamping arm 21 rotates around the first hinged ear 221 with the locking bolt as the axis. One end of the locking bolt 231 passes through the clamping arm 21 and the first hinged ear 221 and is threadedly connected to the nut 232. In this locking assembly 23, the locking bolt 231 plays the role of a rotation axis, and is used in conjunction with the nut 232 to limit the relative rotation between the clamping arm 21 and the first hinged ear 221.

[0041] In the case where the first collar 22 is fixedly connected to the clamping arm 21 and the locking bolt 231 and the nut 232 are used as the locking assembly 23, the present application also optimizes the clamping arm 21. The clamping arm 21 includes a connecting body 212 and a clamping arm body 213. The proximal end of the connecting body 212 is used to be fixedly connected or hinged to the first collar 22. Specifically, the proximal end of the connecting body 212 is fixedly connected or hinged to the first hinge ear 221. The two clamping arm bodies 213 are fixedly arranged on the end surface of the distal end of the connecting body 212, and a gap is formed between the two clamping arm bodies 213, which is used to clamp the material. A locking bolt 214 is arranged at the distal end of the clamping arm body 213, and the locking bolt 214 provides a locking force for the clamping arm body 213, so that the two clamping arm bodies 213 are close to each other to prevent the material from falling.

[0042] The present application also provides another structure of the locking assembly 23, such as Figure 4 Another structure of the locking assembly 23 includes a second ring 233 and a plurality of support arms 234. The second ring 233 is sleeved on the support body 1, and a plurality of second hinged ears 235 are arranged on the circumference of the second ring 233. The second hinged ears 235 are connected to the support arms 234. The proximal end of the support arm 234 is hinged to the second hinged ears 235, and a limiting pin 236 is arranged at the distal end.

[0043] The first collar 22 is also provided with a first hinged ear 221 on its circumference, and the proximal end of the clamping arm 21 is hinged to the first hinged ear 221. The clamping arm 21 is provided with a slide groove 211, which is provided at the distal end of the clamping arm 21. The aforementioned limit pin 236 is provided in the slide groove 211, and the limit pin 236 can slide and rotate in the slide groove 211.

[0044] A second positioning assembly (not shown in the figure) is also provided on the second collar 233 , and the second positioning assembly is used to limit the axial position of the second collar 233 on the support body 1 .

[0045] The first positioning assembly and the second positioning assembly are both bolts, which are screwed to the first sleeve ring 22 or the second sleeve ring 233 and then abut against the support body 1 to fix the first sleeve ring 22 or the second sleeve ring 233 .

[0046] like Figure 5 In the case where the second collar 233 and the support arm 234 are used as the locking assembly 23, the present application also provides a corresponding clamping arm 21. Specifically, the clamping arm 21 includes a connecting body 212 and a clamping arm body 213. The proximal end of the connecting body 212 is used to be hinged to the first collar 22. Specifically, the proximal end of the connecting body 212 is hinged to the first hinge ear 221. The two clamping arm bodies 213 are fixedly arranged on the end surface of the distal end of the connecting body 212 and a gap is formed between the two clamping arm bodies 213. The gap is used to clamp the material. A locking bolt 214 is arranged at the distal end of the clamping arm body 213.

[0047] Furthermore, the slide slot 211 is arranged on the clamp arm body 213 near the support arm 234. When the stop pin 236 is located in the slide slot 211, the end of the stop pin 236 away from the support arm 234 does not exceed the slide slot 211, so as to prevent the stop pin 236 from extending into the gap and blocking the material from entering the gap.

[0048] In order to clamp materials with different thickness specifications, the present application further optimizes the clamping arm 21. Specifically, the clamping arm body 213 on the side away from the support arm 234 is rotatably set on the distal end face of the connecting body 212. At this time, the clamping arm body 213 on the side away from the support arm 234 can be rotated on the distal end face of the connecting body 212 to change the gap size between the two clamping arm bodies 213, so that materials of different thicknesses can be clamped, avoiding scratches and unstable clamping when clamping materials.

[0049] Preferably, the clamp arm body 213 on the side away from the support arm 234 is fixed to the distal end surface of the connecting body 212 by a hinge, and the opening direction of the hinge is toward the other clamp arm body 213. The clamp arm body 213 on the side away from the support arm 234 is chamfered to avoid interference between the two clamp arm bodies 213 during rotation.

[0050] Preferably, a base 3 is further provided at the lower end of the support body 1 , and the base 3 is located below the two clamping parts 2 . The base 3 is a hollow structure so that the plasma can fully contact with the material.

[0051] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
