Description

Technical Field

[0001] The utility model belongs to the technical field of target material binding, and in particular relates to a rotating target material binding and assembling screen auxiliary tooling. Background Art

[0002] The rotating target is a hollow, cylindrical tube that rotates around a fixed bar magnet assembly, uniformly etching the target surface 360 ​​degrees. It offers advantages such as high utilization, good coating continuity, and uniform coating composition. During the binding process, a screen (metal mesh) is required to secure the rotating target to the backing tube.

[0003] The existing method of binding and assembling the screen is usually to tie the flat screen to the back tube with a cable tie. Otherwise, the screen will slide off the back tube and the target material cannot be assembled on the back tube. The existing method has the following disadvantages:

[0004] (1) When the target is put on the back tube, the screen that is not tied with a cable tie at the beginning needs to be manually gathered to the middle and passed through the middle of the target; the area where the screen expands outward needs to be manually pressed against the back tube; when the target continues to slide forward and encounters a cable tie, the cable tie needs to be untied and re-tied after the target passes; and the screen is easily rubbed and lifted during the forward movement of the target, causing wrinkles on the screen. At this time, the target needs to be withdrawn and the screen needs to be flattened before assembly can continue. The existing binding and assembly method of the screen is time-consuming and inefficient.

[0005] (2) Since the mesh joints expand outward during assembly, the edge of the mesh can easily scratch the operator; when the target is assembled on the back tube, the mesh joints will continue to scratch the inner wall of the target, causing the coated indium to peel off; since the entire mesh is still in an outward expansion state after assembly, the joints will always press against the inner wall of the target. When the indium is poured out and the mesh is pulled out, the coated indium on the inner wall of the target under high temperature is more likely to be scratched off by the mesh, causing secondary scratches on the inner wall of the target, affecting product quality.

[0006] In order to enhance the stability and safety of the target during the binding process and improve the binding efficiency, the screen needs to be adjusted to a certain extent so that the screen can be fixed on the back tube without the need for cable ties to prevent the screen from scratching the operator, and to avoid the target being scratched by the screen when passing through the back tube during assembly, and the target inner wall being scratched again when the indium is poured out and the screen is pulled out. Utility Model Content

[0007] In order to solve the above problems, the utility model provides a rotating target binding and assembling screen auxiliary tooling, which can realize the curling adjustment of the screen.

[0008] A rotating target material binding and assembly screen auxiliary tooling, the tooling includes a driving shaft, a driven shaft, and a flexible barrier cloth. The flexible barrier cloth includes a fixed end and a free end. The fixed end is connected to the driving shaft, and the free end passes through the gap between the driving shaft and the driven shaft and extends out of the gap.

[0009] In this solution, one end of the screen is inserted between the flexible barrier cloth and the drive shaft. The flexible barrier cloth restrains the end of the screen, keeping it in contact with the drive shaft. The screen curls as the drive and driven shafts rotate. The flexible barrier cloth limits the end of the screen and the side of the screen facing away from the drive shaft, allowing it to rotate with the drive and driven shafts, achieving a superior curling effect.

[0010] Furthermore, the length of the free end extending from the gap is greater than the cross-sectional circumference of the driving shaft, so that the end of the screen can rotate at least one circle under the restriction of the flexible barrier cloth.

[0011] Furthermore, the two ends of the driving shaft and the two ends of the driven shaft are connected through a transmission device.

[0012] Furthermore, the transmission device is a belt, a chain, or a transmission gear.

[0013] Furthermore, as one of the optional solutions, a driving handle is provided on the driving shaft. As a second optional solution, the driving shaft and the driven shaft are respectively connected to a driving motor.

[0014] Furthermore, the width of the flexible barrier cloth is adapted to the width of the screen, and the size of the gap between the driving shaft and the driven shaft is adapted to the thickness of the screen.

[0015] Furthermore, the flexible barrier cloth is bonded to the driving shaft.

[0016] Furthermore, the flexible barrier cloth is made of glass fiber material.

[0017] Furthermore, the flexible barrier cloth is a mesh cloth.

[0018] Furthermore, the tooling also includes a bracket supporting the driving shaft and the driven shaft; a pulley is provided at the bottom of the bracket.

[0019] Compared with the prior art, one or more of the above technical solutions can achieve at least one of the following beneficial effects:

[0020] This rotary target binding and assembly screen auxiliary tooling adjusts the screen's curvature, features a streamlined structure, and is easy to operate. The tooling rotates and bends the screen, creating a circular, inward-converging shape. When assembling a screen treated with this tooling, the screen simply slides over the backing tube, enveloping it. This improves production efficiency, avoids the safety risk of scratches during screen assembly, and prevents repeated scrapes of the screen edge against the target's inner wall, improving the quality of target binding.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1

[0027] like Figure 1 As shown, an embodiment of the present invention provides a rotating target binding and assembly screen auxiliary tooling, comprising a driving shaft 1, a driven shaft 2, and a flexible barrier cloth 3. The flexible barrier cloth 3 comprises a free end and a fixed end. The fixed end is connected to the driving shaft 1, and the free end passes through the gap between the driving shaft 1 and the driven shaft 2 and extends out of the gap. In this embodiment, the length of the free end extending from the gap is greater than the cross-sectional circumference of the driving shaft 1.

[0028] The two ends of the driving shaft 1 are connected to the two ends of the driven shaft 2 by a transmission device 4, which can be a belt, chain, or transmission gear. As a preferred embodiment, the two ends of the driving shaft 1 and the two ends of the driven shaft 2 are connected by a belt, which saves space, ensures that the driving shaft and the driven shaft rotate in unison, and is relatively low in cost.

[0029] The length of the active shaft 1, the length of the driven shaft 2, and the width of the flexible barrier fabric 3 can be specifically set based on the width of the screen. The gap between the active shaft 1 and the driven shaft 2 can also be specifically set based on the thickness of the screen. It is understood that if the active shaft 1 and the driven shaft 2 are made of a flexible material such as rubber, the active shaft 1 and the driven shaft 2 can be tightly connected, with the gap between them being negligible. Taking advantage of the properties of the material, the screen can be inserted between the active shaft 1 and the driven shaft 2.

[0030] A driving handle 5 is provided on the driving shaft 1 , and the driving handle 5 is arranged at one end or both ends of the driving shaft 1 .

[0031] The flexible barrier cloth 3 is made of glass fiber and is bonded to the driving shaft 1. As a preferred embodiment, the flexible barrier cloth 3 is a mesh cloth. The mesh cloth is based on a medium-alkali or alkali-free glass fiber woven fabric and is treated with an alkali-resistant coating. This product has high strength and good alkali resistance and is commonly used in insulation systems, primarily to prevent the formation of cracks. The mesh cloth used in this embodiment can evenly distribute the stress of the screen during bending. At the same time, the mesh cloth can prevent deformation caused by the collision and extrusion force between the screen and the driving shaft 1 and the driven shaft 2.

[0032] As a specific implementation, the tooling further includes a bracket 6 for supporting the driving shaft 1 and the driven shaft 2 , and a pulley is provided at the bottom of the bracket 6 to facilitate the movement of the tooling.

[0033] The working principle of the rotating target binding and assembly screen auxiliary tooling is as follows:

[0034] Insert one end of the screen 7 to be adjusted between the flexible barrier cloth 3 and the active shaft 1, and limit the end of the screen 7 with the fixed end of the flexible barrier cloth; turn the driving handle 5 to rotate the active shaft 1, and drive the driven shaft 2 to rotate through the belt. After one rotation, there is no need to use the effect of the flexible barrier cloth, and the squeezing of the active shaft 1 and the driven shaft 2 is sufficient. At this point, the screen 7 is curled on the active shaft 1 under the action of the active shaft 1, the driven shaft 2, and the flexible barrier cloth 3. When the screen 7 is curled, turn the driving handle 5 in the opposite direction, and the screen 7 is retracted from the active shaft 1, and the curved screen 7 is obtained, which is circular and gathered inward as a whole.

[0035] The effects of the existing binding and assembling screen method and the binding and assembling screen method after the screen is processed using this auxiliary tooling are compared.

[0036] (1) Binding and assembling screen efficiency;

[0037] Assembly using the existing method: A 2176mm target to be assembled is installed on the back tube. In order to fix the screen on the back tube, four cable ties are needed to fix the screen on the back tube. Due to the small gap between the target and the back tube, when the target reaches the cable tie position during assembly on the back tube, the cable tie needs to be untied to allow the target to pass through and then re-tied. Due to the outward expansion of the screen, the target may rub against the screen when moving forward, causing the screen to be squeezed and warped to form wrinkles, making it impossible for the target to pass through. The target needs to be retreated and the screen needs to be straightened again before it can move forward. Repeating this operation takes a total of 40 to 50 minutes.

[0038] After using the auxiliary tooling of this embodiment: since the screen has been rolled into a circular inward-gathering shape, the screen can be directly put on the back tube and fit tightly to the back tube, and it will not slide, fall, or expand outward; the target material can be directly moved from one end of the back tube to the other, and the total time consumed is 20 to 30 minutes.

[0039] (2) Binding assembly quality;

[0040] Assembly using the existing method: Since the screen is fixed to the back tube with cable ties, most of the edges are still in a raised state; during assembly, when the target material is assembled onto the back tube, the raised edges will continue to scratch the inside of the target material; and after assembly, since the screen as a whole is still in an expanded state, when the indium is turned over and the screen is pulled out, the raised edges will scratch the inner wall of the target material again under high temperature. When the screen is subsequently disassembled and scanned, a line of scratches from bottom to top will be seen.

[0041] After using the auxiliary tooling of this embodiment: the screen is in a circular shape that gathers inward without any warping at the edges, and will not scratch the inner wall of the target during assembly, nor will it scratch again when the indium is turned over and the screen is pulled out, thereby ensuring product quality and production efficiency.

[0042] (3) Security of binding assembly;

[0043] Using the existing assembly method: Since the cable tie only serves to secure the screen to the backing tube, when assembling the target, the screen needs to be manually squeezed onto the backing tube to fit the target and facilitate the target's movement. During this operation, it is easy to hit the edge of the screen, causing punctures or scratches.

[0044] After using the auxiliary tooling of this embodiment: the screen is put on the back tube and can fit tightly with the back tube, and there is no need to manually press the screen, thereby reducing contact and preventing puncture injuries, thereby ensuring production safety.

[0045] This rotary target binding and assembly screen auxiliary tooling has been used in actual engineering applications, achieving excellent curling results. Application of this tooling to the rotary target binding field has improved assembly efficiency and product quality. It also addresses issues such as difficulty securing the screen during rotary target binding and assembly, the risk of injury from the screen edges, scratches on the target's inner wall during assembly, and secondary scratches on the target's inner wall during indium removal and screen removal, which can reduce the quality of the finished product.

[0046] Example 2

[0047] The difference between this embodiment and embodiment 1 lies in the driving mode of the driving shaft and the driven shaft: the driving shaft and the driven shaft are respectively connected to driving motors and driven by different motors; wherein the rotational speed of the driven shaft can be controlled according to the rotational speed of the driving shaft. This control method is a conventional control method and will not be repeated here.

[0048] Obviously, the above embodiments are merely examples for the purpose of clearly illustrating the technical solution of the present invention and are not intended to limit the implementation of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be protected by the claims of the present invention.
