Description

Technical Field

[0001] The utility model relates to the technical field of polycarbonate plate processing equipment, in particular to a feeding component for surface treatment of polycarbonate plate. Background Art

[0002] After polycarbonate sheets are produced and molded, their surface requires treatment to facilitate subsequent UV coating to enhance their performance. Because the surface treatment process for polycarbonate sheets is an assembly-line process, the loading assembly must sequentially pass through the corresponding steps. However, when the loading assembly is used to transport thicker and stronger polycarbonate sheets, some components within the loading assembly can obstruct portions of the sheet's surface near its edges, compromising the comprehensiveness of the surface treatment and the subsequent coating application.

[0003] Existing patent application number: 202410060502.7 discloses a polycarbonate sheet surface treatment device and process. This device uses a conveyor device to vertically guide the polycarbonate sheet, creating a relative isolation between the treatment space and the external environment, preventing harmful gases generated by spraying from escaping and causing harm to the human body. In the above-mentioned prior art, the limiting strips in the conveyor device block the portion of the polycarbonate sheet surface near the boundary when limiting the bottom of the polycarbonate sheet, and the above-mentioned technical problems still exist. Utility Model Content

[0004] The purpose of the present utility model is to provide a feeding assembly for surface treatment of polycarbonate sheets, so as to solve the problem proposed in the above-mentioned background technology that some components will block part of the surface near the boundary of the polycarbonate sheet, thereby affecting the comprehensiveness of the surface treatment of the polycarbonate sheet and the subsequent coating spraying effect.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The utility model provides a feeding assembly for surface treatment of a polycarbonate plate, comprising a top support platform, and the feeding assembly for surface treatment of a polycarbonate plate further comprises:

[0007] An outer limiting ring and an inner limiting ring are fixed to the bottom of the top support platform, the outer limiting ring is located outside the inner limiting ring, and the opposite surfaces of the outer limiting ring and the inner limiting ring are combined to form a guide groove.

[0008] A plurality of sliding seats are slidably sleeved in the guide grooves.

[0009] A supporting frame is arranged between the bottoms of the two sliding seats.

[0010] A clamping portion is provided at the bottom of the supporting frame for laterally clamping both sides of the top of the polycarbonate plate.

[0011] The clamping portion comprises:

[0012] A bidirectional screw rod arranged at the bottom of the supporting frame is rotated horizontally.

[0013] Two flat clamping blocks are relatively threadedly sleeved on the bidirectional screw rod, and the shape of the flat clamping blocks is an inverted L shape. When the two flat clamping blocks move closer to each other, the two flat clamping blocks clamp the outside of the right-angle boundary wrapped around the top of the polycarbonate plate.

[0014] A servo motor is used to drive the bidirectional screw to rotate.

[0015] Furthermore, the directions of the threads on the two ends of the bidirectional screw are opposite, and the bidirectional screw is used to drive the two flat clamping blocks to move linearly towards or away from each other.

[0016] Furthermore, the polycarbonate sheet material surface treatment feeding assembly further comprises:

[0017] A transmission chain is rotatably sleeved in the guide groove.

[0018] A driving part is fixed on the top supporting platform and is used to drive the transmission chain to rotate.

[0019] A plurality of limit push blocks are fixed at the bottom of the transmission chain, and the limit push blocks divide the interior of the guide groove into a plurality of restricted areas.

[0020] Furthermore, the transmission chain is located on the top of the sliding seat, and one side of the sliding seat is overlapped with one side of the limiting push block.

[0021] Furthermore, the sliding seat is rotatably arranged on the top of the supporting frame, and the supporting frame corresponds to the restricted area.

[0022] Furthermore, the flat clamping block has a vertical surface and a horizontal surface inside, and the vertical surface inside the flat clamping block is perpendicular to the surface to be processed on the polycarbonate sheet.

[0023] Furthermore, the polycarbonate plate surface treatment loading assembly further includes two support columns relatively fixed to the bottom of the top support platform.

[0024] Compared with the existing technology, one or more of the above technical solutions have the following beneficial effects:

[0025] 1. The utility model uses a clamping portion suspended from the bottom of the top support to vertically clamp and secure the polycarbonate sheet and feed the polycarbonate sheet to the processing position. By designing the clamping surface of the flat clamping block as a combination of vertical and horizontal surfaces, the clamping surface of the flat clamping block is perpendicular to the surface to be processed of the polycarbonate sheet, without blocking the surface to be processed and thus avoiding affecting the comprehensiveness of the surface treatment and spraying of the polycarbonate sheet.

[0026] 2. The utility model designs a right-angle clamping area formed by the horizontal and vertical surfaces in the flat clamping block. When clamping the polycarbonate sheet, the three boundaries of the polycarbonate sheet can be clamped and fixed. In combination with the polycarbonate sheet surface treatment table limiting the bottom boundary of the polycarbonate sheet, the fixing effect of the polycarbonate sheet is further improved to prevent it from tilting during surface treatment, which affects the surface treatment effect of the polycarbonate sheet.

[0032] In order to enable people skilled in the art to better understand the solution of the present application, the technical solution in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application.

[0033] like Figures 1 to 4 As shown, a feeding assembly for surface treatment of a polycarbonate sheet material includes a top support 1, and the feeding assembly for surface treatment of a polycarbonate sheet material further includes:

[0034] An outer limiting ring 2 and an inner limiting ring 3 are fixed to the bottom of the top support platform 1 , wherein the outer limiting ring 2 is located outside the inner limiting ring 3 , and the opposite surfaces of the outer limiting ring 2 and the inner limiting ring 3 together form a guide groove 4 .

[0035] A plurality of sliding seats 9 are slidably sleeved in the guide groove 4 .

[0036] A supporting frame 10 is provided between the bottoms of the two sliding seats 9 .

[0037] The clamping portion 11 is provided at the bottom of the carrier 10 and is used to laterally clamp the top two sides of the polycarbonate sheet.

[0038] The clamping portion 11 includes:

[0039] The bidirectional screw rod 111 provided at the bottom of the supporting frame 10 is rotated horizontally.

[0040] Two flat clamping blocks 112 are relatively threadedly sleeved on the bidirectional screw rod 111, and an anti-slip layer is fixed on the inner wall of the flat clamping blocks 112. The shape of the flat clamping blocks 112 is an inverted L-shape. When the two flat clamping blocks 112 move closer to each other, the two flat clamping blocks 112 clamp the outside of the right-angle boundary wrapped around the top of the polycarbonate sheet.

[0041] A servo motor 113 is used to drive the bidirectional screw rod 111 to rotate.

[0042] By controlling the servo motor 113 in the clamping part 11 to drive the bidirectional screw rod 111 to rotate clockwise, the two flat clamping blocks 112 on the bidirectional screw rod 111 will approach each other until they are clamped on the two right-angled boundaries at the top of the polycarbonate sheet, thereby completing the clamping and fixing operation of the polycarbonate sheet. When the polycarbonate sheet is fixed, its top boundary and vertical boundary respectively conflict with the two inner walls of the flat clamping blocks 112, which can not only fix the polycarbonate sheet under the action of the clamping force, but also increase the friction between the flat clamping blocks 112 and the polycarbonate sheet through the anti-slip layer, thereby improving its stability during the subsequent surface treatment process and preventing the polycarbonate sheet from tilting and affecting its surface treatment and spraying effect.

[0043] In this embodiment, the external threads at both ends of the bidirectional screw rod 111 are in opposite directions. The bidirectional screw rod 111 is used to drive the two flat clamping blocks 112 to move linearly closer to or farther away from each other. The rotation direction of the bidirectional screw rod 111 can be controlled by controlling the output end of the servo motor 113 to rotate clockwise or counterclockwise, thereby controlling the two flat clamping blocks 112 on the bidirectional screw rod 111 to move closer to or farther away from each other, thereby achieving clamping, fixing or releasing of the polycarbonate sheet.

[0044] In this embodiment, the polycarbonate sheet material surface treatment feeding assembly further includes:

[0045] A transmission chain 5 is rotatably sleeved in the guide groove 4 .

[0046] A driving part 6 is fixed on the top support platform 1 and is used to drive the transmission chain 5 to rotate.

[0047] Several limit push blocks 7 are fixed to the bottom of the transmission chain 5, and the limit push blocks 7 divide the interior of the guide groove 4 into several restricted areas 8. The surface treatment equipment and spraying equipment of the polycarbonate sheet can be distributed in different positions directly below the guide groove 4 in sequence, so that the transmission chain 5 passes through the surface treatment equipment and the spraying equipment in sequence, and the polycarbonate sheet is loaded into the two in sequence, forming a flow-type processing method, thereby improving the processing efficiency of the polycarbonate sheet.

[0048] The transmission chain 5 is located on the top of the sliding seat 9 , and one side of the sliding seat 9 is overlapped with one side of the limiting push block 7 .

[0049] The sliding seat 9 is rotatably mounted on the top of the supporting frame 10 , and the supporting frame 10 corresponds to the restricted area 8 .

[0050] The transmission chain 5 and the limit push block 7 are driven by the driving part 6 to rotate synchronously in the circumferential direction, so that the two sliding seats 9 in the restricted area 8 are pushed by the limit push block 7 to slide synchronously in the circumferential direction in the guide groove 4, so that the sliding seat 9 drives the supporting frame 10 and the clamping part 11 to move, and when the sliding seat 9 slides through the arc path in the guide groove 4, the sliding seat 9 and the supporting frame 10 rotate relative to each other, so that the supporting frame 10 and the clamping part 11 can smoothly pass through the arc path part of the guide groove 4, so that the clamping part 11 can slide in the circumferential direction under the drive of the driving part 6 and form a closed loop.

[0051] In this embodiment, the interior of the flat clamping block 112 is a vertical surface and a horizontal surface, and the vertical surface inside the flat clamping block 112 is perpendicular to the surface to be treated on the polycarbonate sheet. Such a design effectively avoids blocking the surface to be treated of the polycarbonate sheet during the clamping, fixing and loading process of the polycarbonate sheet, thereby improving the comprehensiveness of the surface treatment of the polycarbonate sheet and avoiding the occurrence of treatment dead corners that affect the surface treatment effect of the polycarbonate sheet.

[0052] In this embodiment, the loading assembly for surface treatment of polycarbonate sheets also includes two support columns 12 relatively fixed to the bottom of the top support platform 1. The support columns 12 are used to lift the top support platform 1 to a certain height to facilitate vertical fixation and loading of the polycarbonate sheets, thereby reducing the difficulty of their surface treatment and spraying operations.

[0053] Working principle: As the transmission chain 5 passes through the interior of the surface treatment equipment and the spraying equipment in sequence, and the transmission chain 5 realizes reciprocating rotation in the circumferential direction under the drive of the driving part 6, the transmission chain 5 drives the limit push block 7 to move synchronously, and the limit push block 7 will push the sliding seat 9 in the restricted area 8 to slide synchronously in the guide groove 4, realizing the synchronous movement of the driving carrier 10 and the clamping part 11 set at the bottom thereof. During its movement, the polycarbonate sheet is clamped and fixed in the clamping part 11 at a specified position just below the transmission chain 5, so that the two right-angle boundaries of the top of the polycarbonate sheet are clamped in two flat The polycarbonate sheet is clamped in the clamping block 112, and the top boundary and vertical boundary of the polycarbonate sheet are respectively in contact with the horizontal surface and vertical surface in the flat clamping block 112, thereby improving the fixing effect of the polycarbonate sheet and improving its stability during the loading process. After the polycarbonate sheet is fixed, it is indirectly driven circumferentially by the driving part 6, so that it passes through the surface treatment equipment and the spraying equipment in turn. After the polycarbonate sheet completes the surface treatment and spraying operations in turn, the clamping part 11 is controlled to release the polycarbonate sheet to realize its unloading. This cycle is repeated to realize the assembly line processing of the polycarbonate sheet and improve its processing effect.

[0054] The above description is merely a preferred embodiment of the present invention. Any portion not described in the present invention can be implemented by adopting or drawing upon existing technologies. Of course, the above description is not intended to limit the present invention, nor is the present invention limited to the above examples. Any changes, modifications, additions, or substitutions made by those skilled in the art within the spirit and scope of the present invention shall also fall within the scope of protection of the present invention.
