The feeding module provides film material. The second Y-axis drive unit drives the second mounting base to move in the Y-axis direction, causing the second roller mounted on the second mounting base to move one end of the film material close to the product mounting rod. The second Z-axis drive unit of the vertical plate drives the first mounting base to move in the Z-axis direction, causing the first roller mounted on the first mounting base to press the high-temperature adhesive tape with non-adhesive film attached onto the round tube. The cutting mechanism cuts the film, and the first rotary power unit drives the product mounting rod to rotate, causing the round tube to rotate synchronously, thereby covering the round tube with the film. At the same time, the second roller further rolls the film covering the round tube, making the film adhere more tightly to the round tube, completing the covering of the round tube with the non-adhesive film with high-temperature adhesive tape. The round tube transport mechanism removes the round tube from the product mounting rod for unloading.

[0057] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0058] like Figures 1 to 10As shown, the device for coating a round tube with a non-adhesive film material according to an embodiment of the present invention includes a worktable 1, a product placement mechanism 2, a film material feeding mechanism 3, a cutting mechanism 4, and a round tube transport mechanism 5. The product placement mechanism 2 includes a first Y-axis drive unit 21, a first frame 22, a first Z-axis drive module 23, a fixed plate 24, a product mounting module 25, a fixed vertical plate 26, and a second Z-axis drive module 27. The first Y-axis drive unit 21 is mounted on the worktable 1 and is connected to the first frame 22. The first Z-axis drive module 23 is mounted on the first frame 22 and is connected to the fixed plate 24. The product mounting module 25 includes a product mounting rod 251 and a first rotary power unit 252, which is mounted on the fixed plate 24 and connected to the product mounting rod 251. The fixed vertical plate 26 is vertically mounted on the fixed plate 24. The second Z-axis drive module 27 includes a second Z-axis drive unit 271. The first mounting base 272 and the first roller 273 are mounted on the fixed vertical plate 26. The first mounting base 272 and the second Z-axis drive unit 271 are connected in a transmission manner. The first roller 273 is mounted on the first mounting base 272. The film material feeding mechanism 3 includes a feeding module 31 and a film material Y-axis motion module 32. The feeding module 31 is mounted on the worktable 1 and is used to provide film material 91. The film material Y-axis motion module 32 is mounted on the feeding module 31. The film material Y-axis motion module 32 includes a second Y-axis drive unit 321, a second mounting base 322 and a second roller 323. The second Y-axis drive unit 321 and the second mounting base 322 are connected in a transmission manner. The second roller 323 is mounted on the second mounting base 322. The cutting mechanism 4 is mounted on the worktable 1. The round tube conveying mechanism 5 is mounted on the worktable 1.

[0059] The first Y-axis drive unit 21, mounted on the workbench 1, drives the first frame 22 to move in the Y-axis direction to a preset position. The first Z-axis drive module 23, mounted on the first frame 22, drives the fixed plate 24 to move in the Z-axis direction to a preset position. After the product mounting module 25, mounted on the fixed plate 24, reaches the preset position, the round tube transport mechanism 5 inserts the round tube 92 into the product mounting rod 251 of the product mounting module 25. The feeding module 31 provides the film material 91. The second Y-axis drive unit 321 drives the second mounting base 322 to move in the Y-axis direction, causing the second roller 323 mounted on the second mounting base 322 to move one end of the film material 91 close to the product mounting rod 251. The fixed vertical plate 26 is mounted on... The second Z-axis drive unit 271 drives the first mounting base 272 to move in the Z-axis direction, causing the first roller 273 mounted on the first mounting base 272 to press the high-temperature tape with non-adhesive film 91 attached to the round tube 92; the cutting mechanism 4 cuts the film 91, and the first rotation power unit 252 drives the product mounting rod 251 to rotate, causing the round tube 92 to rotate synchronously, so that the film 91 covers the round tube 92. At the same time, the second roller 323 further rolls and presses the film 91 covering the round tube 92, so that the film 91 and the round tube 92 are more tightly attached, completing the covering of the round tube 92 with the non-adhesive film 91 with high-temperature tape. The round tube conveying mechanism 5 takes the round tube 92 out of the product mounting rod 251 for unloading. This invention uses a device that uses a non-adhesive film to wrap a round tube, which automatically wraps the round tube 92 with a non-adhesive film 91 with high-temperature tape, replacing manual wrapping. This improves the wrapping efficiency, and the attached high-temperature tape can withstand high temperatures, preventing the tape from melting and sticking to the round tube 92 and becoming impossible to remove.

[0060] like Figure 9 and Figure 10 As shown, in some embodiments, the product mounting module 25 further includes two bearings 253, a wheel 254, and a first sensor 255. The product mounting rod 251 passes through the through holes of the two bearings 253 and is fixedly connected to the inner rings of the two bearings 253. The fixed vertical plate 26 is provided with mounting holes 261, through which the product mounting rod 251 passes. The front and back sides of the fixed vertical plate 26 are provided with mounting grooves 262, which are located at the mounting holes 261. The two bearings 253 are respectively embedded in the two mounting grooves 262. The product mounting rod 251 passes through the through hole of the wheel 254 and is fixedly connected to the wheel 254. The edge of the wheel 254 is provided with a notch. The first sensor 255 is mounted on the fixed plate 24, and the wheel 254 passes over the first sensor 255.

[0061] Since the two bearings 253 are respectively embedded in the two mounting grooves 262, the product mounting rod 251, which passes through the through holes of the two bearings 253 and is fixedly connected to the inner rings of the two bearings 253, can be limited in the X-axis direction without affecting the rotation of the product mounting rod 251. Since the edge of the wheel 254 is provided with a notch, and the wheel 254 passes over the first sensor 255, the first sensor 255 can detect the number of rotations of the wheel 254 through the notch and feed it back to the controller.

[0062] like Figure 7 As shown, in some embodiments, the first mounting base 272 includes a base plate 2721, an adjusting bracket 2722, an adjusting shaft 2723, and a second fork 2724. The base plate 2721 is connected to the second Z-axis drive unit 271. The adjusting bracket 2722 includes a first top plate 2725 and a first side plate 2726. The first top plate 2725 and the first side plate 2726 are fixedly connected to form an L-shaped structure. The first top plate 2725 and the first side plate 2726 are fixed to the base plate 2721. One end of the adjusting shaft 2723 passes through the first top plate 2725 and is connected to a knob 2727. The other end of the adjusting shaft 2723 is connected to the second fork 2724. The first side plate 2726 is provided with a second slide rail 2728. The second fork 2724 is slidably connected to the second slide rail 2728. The first roller 273 is mounted on the second fork 2724 through a rotating shaft.

[0063] The second Z-axis drive unit 271 drives the first roller 273 on the first mounting base 272 to move in the Z-axis direction, thereby making the first roller 273 contact the film material 91 on the circular tube 92. When the product mounting rod 251 drives the circular tube 92 to rotate, the first roller 273 can roll the film material 91 onto the surface of the circular tube 92. In order to enable the first roller 273 to better contact the film material 91 on the surface of the circular tube 92, the adjustment shaft 2723 can be rotated in and out of the second fork 2724 by turning the knob 2727. When the knob 2727 is adjusted, the second fork 2724 will move along the second slide rail 2728, thereby changing the distance between the second fork 2724 and the first top plate 2725, thereby changing the height of the second fork 2724, and ultimately changing the contact pressure between the first roller 273 and the film material 91 on the surface of the circular tube 92.

[0064] like Figure 7 As shown, in some embodiments, the product placement mechanism 2 further includes a feeding module 28, which includes a second X-axis drive unit 281 and a third fork 282. The second X-axis drive unit 281 is mounted on the fixed vertical plate 26, and the third fork 282 is connected to the second X-axis drive unit 281 in a transmission manner. The product installation module 25 also includes a clamping tube 256, which is sleeved on the product installation rod 251. The clamping tube 256 is provided with an annular groove 2561, and the third fork 282 is engaged with the annular groove 2561.

[0065] When the tube handling mechanism 5 is unloading material, it needs to remove the film-coated tube 92 from the product mounting rod 251. Since the tube 92 is tightly fitted, the film material 91 is easily damaged during the removal process from the product mounting rod 251. Therefore, by setting up the unloading module 28, the unloading module 28 cooperates with the tube handling mechanism 5 to ensure that the film material 91 covered by the tube 92 is not damaged by the tube handling mechanism 5. The second X-axis drive unit 281 drives the third fork 282 to move in the X-axis direction. Since the third fork 282 cooperates with the clamping tube 256 of the product mounting module 25, the clamping tube 256 is sleeved on the product mounting rod 251 and the clamping tube 256 is provided with an annular groove 2561. The third fork 282 is engaged with the annular groove 2561. Therefore, the clamping tube 256 can push the coated round tube 92 out of the product mounting rod 251, and then cooperate with the round tube transport mechanism 5 to transport and unload the material. This avoids the round tube transport mechanism 5 directly clamping out the coated round tube 92, thereby ensuring the yield of the film material 91 on the surface of the round tube 92.

[0066] like Figure 7 As shown, in some embodiments, the first frame 22 includes a base plate 221, two side plates 222 and a top plate 223. The two side plates 222 are located between the base plate 221 and the top plate 223. The top and bottom ends of the side plates 222 are fixedly connected to the top plate 223 and the base plate 221, respectively. The top plate 223 is provided with five through holes, one of which is located at the center of the top plate 223 and the other four are located at the four corners of the top plate 223.

[0067] The first Z-axis drive module 23 includes a first Z-axis drive unit 231, a guide assembly 232, and a limiting assembly 233. The first Z-axis drive unit 231 is mounted on the bottom surface of the top plate 223. The drive shaft of the first Z-axis drive unit 231 passes through a through hole located at the center of the top plate 223 and is fixedly connected to the fixed plate 24. The guide assembly 232 includes two guide plates 2321 and four guide posts 2322. The four guide posts 2322 pass through through holes located at the four corners of the top plate 223. One end of the guide post 2322 is fixedly connected to the fixed plate 24. One end of two guide posts 2322 is fixedly connected to the guide plate 2321, and one end of the other two guide posts 2322 is fixedly connected to the other guide plate 2321. The limiting assembly 233 includes two limiting members 2331, which are fixedly fixed to the top surfaces of the two guide plates 2321.

[0068] The first Z-axis drive unit 231 drives the fixed plate 24 to move in the Z-axis direction, thereby adjusting the height of the product mounting rod 251 to a suitable position with the second roller 323, so that the film material 91 can contact the circular tube 92 to complete the coating. To improve the stability of the fixed plate 24, a guide assembly 232 is provided. By passing one end of each of the four guide posts 2322 through the through holes located at the four corners of the top plate 223 and fixing them to the fixed plate 24, and fixing the other end to the guide plate 2321, the stability of the fixed plate 24's movement is ensured when the first Z-axis drive unit 231 drives the fixed plate 24. At the same time, to prevent the product mounting rod 251 from moving beyond its range, a limiting assembly 233 is provided to limit the movement range of the fixed plate 24. A limiting member 2331 is also provided on the fixed plate 24 to limit the distance between the fixed plate 24 and the first frame 22.

[0069] like Figure 1 and Figure 2 As shown, in some embodiments, a cable chain 7 is also included. The cable chain 7 is installed on the workbench 1, and the first frame 22 is provided with a fixing member 224. One end of the cable chain 7 is fixedly connected to the fixing member 224.

[0070] By installing the cable chain 7 on the workbench 1 and fixing one end of the cable chain 7 to the fixing member 224 of the first frame 22, since the cable chain 7 can accommodate the wires, and the controller is electrically connected to the first Z-axis drive module 23 installed on the first frame 22 through the wires, the cable chain 7 can ensure the routing of the wires when the first Y-axis drive unit 21 drives the first frame 22 to move along the Y-axis direction, thus avoiding the wires affecting the movement of the first frame 22.

[0071] like Figure 5 As shown, in some embodiments, the cutting mechanism 4 includes a second frame 41, a third X-axis drive unit 42, a cutting seat 43, and a cutting machine 44. The second frame 41 is mounted on the workbench 1, the third X-axis drive unit 42 is mounted on the second frame 41, the cutting seat 43 is connected to the third X-axis drive unit 42 in a transmission connection, and the cutting machine 44 is mounted on the cutting seat 43.

[0072] After the membrane material 91 has covered the round tube 92, the third X-axis drive unit 42 installed on the second frame 41 drives the cutting seat 43 to move along the X-axis direction, thereby moving the cutting blade of the cutting machine 44 to the membrane material 91. The cutting machine 44 drives the cutting blade to cut the membrane material 91, thereby cutting the membrane material 91 covering the round tube 92 from the membrane material feeding mechanism 3.

[0073] like Figure 2 and Figure 6As shown, in some embodiments, a lifting mechanism 8 is also included. The lifting mechanism 8 includes a mounting plate 81, a first X-axis drive unit 82, a first slide rail 83, a mounting vertical plate 84, a third Z-axis drive unit 85, and a first fork 86. The mounting plate 81 is mounted on the worktable 1. The first X-axis drive unit 82 and the first slide rail 83 are mounted on the mounting plate 81. The mounting vertical plate 84 is drivenly connected to the first X-axis drive unit 82 and slidably connected to the first slide rail 83. The third Z-axis drive unit 85 is mounted on the mounting vertical plate 84, and the first fork 86 is drivenly connected to the third Z-axis drive unit 85.

[0074] The first Y-axis drive unit 21 drives the first frame 22 to move in the Y-axis direction, so that the product mounting rod 251 and the fork of the first fork 86 of the lifting mechanism 8 are at the same position on the Y-axis. After the round tube 92 is fitted into the product mounting rod 251 by the round tube transport mechanism 5, the first X-axis drive unit 82 can drive the mounting vertical plate 84 to slide along the X-axis direction on the first slide rail 83, so that the third Z-axis drive unit 85 installed on the mounting vertical plate 84 moves to below the product mounting rod 251, and then the third Z-axis drive unit 85 drives the first fork 86 to move along the Z-axis direction until the fork engages with the round tube 92 placed on the product mounting rod 251. The diameter of the tube 92 is matched with the diameter of the pipe. Then, the tube 92 is precisely positioned by the cooperation of the first X-axis drive unit 82 and the third Z-axis drive unit. After the lifting mechanism 8 completes the precise positioning of the tube 92, the first X-axis drive unit 82 drives the mounting plate 84 to reset, the third Z-axis drive unit 85 drives the first fork 86 to reset, the feeding module 31 provides the film material 91 to the film material Y-axis motion module 32, and the second Y-axis drive unit 321 of the film material Y-axis motion module 32 drives the second mounting base 322 to move along the Y-axis direction, so that the second roller 323 mounted on the second mounting base 322 moves the film material 91 to contact the tube 92.

[0075] Preferably, limiting members are fixedly connected to both ends of the mounting plate 81 along the X-axis direction, and support plates are fixedly connected to both ends of the mounting vertical plate 84 along the X-axis direction. The limiting members can abut against the support plates, thereby limiting the movement range of the mounting vertical plate 84 when the first X-axis drive unit 82 drives the mounting vertical plate 84 to move along the X-axis direction, and preventing the mounting vertical plate 84 from moving beyond its position, which would cause the fork of the first fork 86 to be unable to engage with the round tube 92.

[0076] like Figures 2 to 4As shown, in some embodiments, the feeding module 31 includes a third frame 311, a first material plate 312, a second material plate 313, a third material plate 314, a material roller 315, three guide rollers 316, a power roller 317, a second rotary power unit 318, a guide rail 319, two second sensors 3110, a sliding seat 3111, a detection element 3112, a fourth Z-axis drive unit 3113, a third mounting seat 3114, and a third roller 3115;

[0077] The third frame 311 includes a third base plate 3101, two third side plates 3102, a limiting top plate 3103, and a support platform 3104. The third base plate 3101 is installed on the workbench 1. The bottom ends of the two third side plates 3102 are fixedly connected to the third base plate 3101, and the top ends of the two third side plates 3102 are fixedly connected to the limiting top plate 3103. The limiting top plate 3103 is provided with a limiting groove 3105. The support platform 3104 is installed on the third side plates 3102, and the second Y-axis drive unit 321 is installed on the support platform 3104.

[0078] The first material plate 312 is fixedly connected to the back of the third side plate 3102, the second material plate 313 is fixedly connected to the back of the first material plate 312, and the third material plate 314 is fixedly connected to the front of the first material plate 312. The first material plate 312 is provided with a through groove 3121.

[0079] The material roller 315 and two of the guide rollers 316 are mounted on the first material plate 312. One of the guide rollers 316 passes through the through groove 3121 and is mounted on the sliding seat 3111. The guide rail 319 is mounted on the second material plate 313. The sliding seat 3111 is slidably connected to the guide rail 319. The detection element 3112 is mounted on the sliding seat 3111. Two second sensors 3110 are respectively mounted on both ends of the guide rail 319.

[0080] The second rotary power unit 318 is installed on the first material plate 312, and the power roller 317 is connected to the second rotary power unit 318 in a transmission connection.

[0081] The fourth Z-axis drive unit 3113 is mounted on the third material plate 314, the third mounting base 3114 is connected to the fourth Z-axis drive unit 3113 in a transmission connection, and the third roller 3115 is mounted on the third mounting base 3114.

[0082] The feed roller 315 can provide the film material 91. When the film material 91 is used up, the feed roller 315 can be replaced with a new feed roller 315. The film 91 unwound by the feed roller 315 passes sequentially through the power roller 317, three guide rollers 316, and the limiting groove 3105 of the limiting top plate 3103. Among them, the two guide rollers 316 are located on the same horizontal line, and the guide roller 316 installed with the sliding seat 3111 is located between the two guide rollers 316. The film 91 first passes through the guide roller 316 close to the power roller 317, then passes through the guide roller 316 installed with the sliding seat 3111, and finally passes through the guide roller 316 close to the limiting top plate 3103. The second rotary power unit 318 can make the power roller 317 roll, and at the same time, the fourth Z-axis drive unit 3113 drives the third roller 3115 to move in the Z-axis direction, so that the third roller 3115 and the power roller 317 clamp the film 91, thereby driving the feed roller 315 to unwound the film 91. A guide roller 316 is mounted on the sliding seat 3111, thus changing the tension of the film 91 during the unwinding process, thereby ensuring the length of the film 91 covering the circular tube 92. Since the film 91 needs to move towards the circular tube 92 in the Y-axis direction together with the second roller 323 driven by the second Y-axis drive unit 321, the guide roller 316 moves from the bottom to the top of the through groove 3121 during this process. Simultaneously, two second sensors 3110 can sense the movement of the detection element 3112. When the second roller 323 driven by the second Y-axis drive unit 321 moves away from the circular tube 92 covered with the film 91 in the Y-axis direction, the sliding seat 3111 also resets from the top to the bottom of the groove, ensuring that the film 91 in the limiting groove 3105 maintains tension. The controller can also control the product placement mechanism 2 through signals fed back from the second sensors 3110.

[0083] like Figure 11 and Figure 12 As shown, in some embodiments, the circular tube handling mechanism 5 includes a base 51, a large arm 52, a small arm 53, a robotic arm electrical assembly 54, and a gripping assembly 55. The base 51 is mounted on the workbench 1. The large arm 52 is connected to the base 51 via a rotating shaft. The small arm 53 is connected to the large arm 52 via a rotating shaft. The robotic arm electrical assembly 54 is mounted on the small arm 53. The robotic arm electrical assembly 54 is electrically connected to the base 51 via a pipe fitting. The robotic arm electrical assembly 54 is provided with a drive shaft 56, which is drively connected to the gripping assembly 55.

[0084] Preferably, the gripping assembly includes a gripping frame 551, a first drive unit 552, a movable base 553, a second drive unit 554, and a gripper 555. The first drive unit 552 is mounted on the gripping frame 551 and is convexly connected to the movable base 553. The second drive unit 554 is mounted on the movable base 553, and the gripper 555 is convexly connected to the second drive unit 554.

[0085] The clamping component 55 of the round tube handling mechanism 5 can insert the round tube 92 to be coated into the product mounting rod 251, and can also remove the coated round tube 92 from the product mounting rod 251. The upper arm 52 is connected to the base 51 through a rotating shaft, so the upper arm 52 can rotate to move the lower arm 53 closer to the product mounting rod 251. The lower arm 53 is connected to the upper arm 52 through a rotating shaft, so the lower arm 53 can rotate to move the clamping component 55 closer to the product mounting rod 251. The robotic arm electrical assembly 54 uses a transmission shaft 56 to make the round tube 92 gripped by the gripper 555 of the clamping component 55 and the product mounting rod 251 on the same horizontal plane. The first drive unit 552 of the clamping component 55 drives the round tube 92 to be inserted into the product mounting rod 251. Then, the second drive unit 554 of the clamping component 55 drives the gripper 555 to separate. The first drive unit 552 drives the second drive unit 554 to reset, completing the loading of the round tube 92 to be coated.

[0086] After the round tube 92 is coated, the first drive unit 552 of the clamping assembly 55 drives the two grippers 555 to move to both sides of the round tube 92. Then, the second drive unit 554 of the clamping assembly 55 drives the grippers 555 to close, thereby clamping the round tube 92. The first drive unit 552 drives the second drive unit 554 to reset, and the forearm 53 and the upper arm 52 rotate to move the round tube 92 to the unloading position. The robotic arm electrical assembly 54 drives the clamping assembly 55 to change the height in the Z-axis direction through the transmission shaft 56. The second drive unit 554 drives the grippers 555 to separate, thereby completing the unloading of the round tube 92.

[0087] It should be noted that the first Y-axis drive unit 21, the first Z-axis drive unit 231, the second Z-axis drive unit 271, the fourth Z-axis drive unit 3113, the second Y-axis drive unit 321, the third X-axis drive unit 42, the first drive unit 552, the second drive unit 554, the second X-axis drive unit 281, the first X-axis drive unit 82, and the third Z-axis drive unit 85 mentioned above can all be electric cylinders. The first rotary power unit 252 and the second rotary power unit 318 can both be stepper motors.

[0088] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
