Background Technology

[0002] Currently, the manufacturing industry is facing labor shortages, rising environmental awareness, increased labor and operating costs, and pressure to transform from labor-intensive to technology-intensive industries. Most businesses are responding to rising manufacturing costs by relocating industries overseas or introducing foreign workers, which can reduce manpower, manufacturing hours, and increase production capacity. However, in response to the industry's large demand for labor, there is a severe labor shortage, which has seriously affected the output of the manufacturing industry and directly affected the fluctuation and instability of prices.

[0003] Furthermore, in the automated operation of production lines in the manufacturing industry, various manufacturing and processing stations within the factory are used to carry out various processing, cutting, joining, and assembly processes. Pre-processing of the workpieces to be processed is particularly important to ensure the stability and smooth connection of subsequent production operations. However, this kind of production operation that uses manual pre-processing is quite time-consuming and labor-intensive, and cannot achieve the effect of rapid manufacturing and production, let alone meet the needs of automated processes and special processing processes.

[0004] Therefore, how to solve the problems and difficulties in connecting pre-processing with subsequent production operations during the processing, and the troubles and deficiencies of manual alignment, cutting, and joining, is the direction that relevant manufacturers in this industry are eager to research and improve.

[0018] A fabric end trimming method for automated fabric splicing, characterized by comprising a worktable and a fabric end trimming device, wherein the fabric end trimming method is implemented according to the following steps:

[0019] (A01) Each clamping drive unit of the rotary clamping device of the workbench drives each clamping part, and each clamping part clamps the preset material roll with the preset material roll end located on the preset feeding device.

[0020] (A02) The first rotary power unit of the rotary clamping device drives the support part to rotate so that the preset material roll held by each clamping part is displaced to one side of the fabric end trimming device. The displacement power unit of the workbench drives the displacement device to move the fabric end trimming device to one side of the preset material roll.

[0021] (A03) The second rotary power unit drives the transmission group in the support part adjacent to the second rotary power unit to rotate each clamping part to drive the preset material roll to rotate, so that the preset material roll end of the preset material roll hangs down to the guide port of the guide group of the pressing device of the fabric end trimming device.

[0022] (A04) The preset sensing component installed on the pressing device of the fabric end trimming device detects the preset material roll end falling down to the guide port, and then controls each pressing drive unit of the pressing group of the pressing device to drive the two pressing rods to move, and a pressing space is formed inside the two pressing rods so that the preset material roll end can fall down into the pressing space. At this time, the preset sensing component controls each pressing drive unit to drive the two pressing rods to reset so that the preset material roll end is pressed at the two pressing rods. At the same time, the second rotating power unit drives the transmission group in the support part on the side of the adjacent second rotating power unit to stop the rotation of each clamping part.

[0023] (A05) The cutting drive unit of the cutting group of the fabric end trimming module of the fabric end trimming device drives the cutting seat to move into the cutting space of the holding group, so that the cutter of the cutting seat can abut against the inner surface of the preset material roll end, and the moving force unit drives the fabric end trimming module to move so as to drive the cutter to cut along the inner surface of the preset material roll end.

[0024] (A06) The platform drive unit of the fabric end trimming module of the fabric end trimming device drives the second support platform of the working platform to move along the trimming space direction of the pressing group, so that the roller seat of the tape group, the abutment of the spot welding group, the spot welding part, and the tape cutting tool of the tape cutting group can simultaneously extend into the trimming space and rest against the inner surface of the pre-set material roll end after cutting.

[0025] (A07) The rubber wheel power unit of the tape assembly drives the recycling wheel to rotate, so as to drive the tape of the tape wheel to enter along the slotted side of the abutment and exit from the other side, causing the tape film to separate from the tape, so that the tape film can be attached to the inner surface of the preset material roll end. At this time, the abutment drive unit of the spot welding assembly drives the abutment to abut against the inner surface of the preset material roll end, and the spot welding drive unit of the spot welding assembly drives the spot welding head of the spot welding member to spot weld the tape film attached to the inner surface of the preset material roll end, so that the tape film can be adhered to the inner surface of the preset material roll end.

[0026] (A08) The moving force unit drives the fabric end trimming module to reset, thereby driving the continuous application of the adhesive film of the tape of the tape group, the continuous abutment operation of the spot welding group, and the continuous spot welding operation of the spot welding component.

[0027] (A09) The abutting drive unit drives the abutting part to reset, the spot welding drive unit drives the spot welding part to reset, the recycling wheel of the tape group stops rotating, and the tape cutting drive unit of the tape cutting group drives the tape cutting seat to move so that the tape cutting tool can cut the adhesive film of the tape on the inner surface of the preset material roll end and reset after cutting.

[0028] (A10) The platform drive unit drives the second support platform of the working platform to reset, and drives the transmission group in the support part on the side of the second rotary power unit to drive each clamping part to rotate the preset material roll. After the preset material roll end is rolled back onto the preset material roll, the rotation of each clamping part is stopped.

[0029] (A11) The first rotary power unit of the rotary clamping device drives the support to rotate so that the preset roll of material held by each clamping part is displaced to one side of the clamping device. The second rotary power unit drives the transmission group in the support on the side of the second rotary power unit to rotate each clamping part to be positioned opposite the clamping device.

[0030] (A12) The displacement power unit of the conveying equipment drives the displacement device to reset, and the clamping device clamps the preset material roll end, and the conveying equipment transports the preset material roll end to the fabric splicing equipment for subsequent processing.

[0031] This invention features a fabric end trimming module equipped with a pressing device and a fabric end trimming device on one side of the conveying equipment of the workbench. The pre-roll end of the pre-roll material is guided by the guide group of the pressing device and passes through the two pressing rods of the pressing group to achieve a pressing state. The fabric end trimming module is used to trim the end of the pre-roll material. The fabric end trimming module includes a cutting group, a tape group, a spot welding group, and a tape cutting group to perform automated pre-processing trimming operations on the end of the pre-roll material, thereby achieving the goals of convenience, speed, and saving time and labor.

[0048] The workbench 1 includes a conveying device 11, a preset feeding device 12 disposed on one side of the conveying device 11, a fabric receiving device 13 disposed on the other side of the conveying device 11 opposite to the feeding device 12, a rotating clamping device 14 disposed on the upper outside of the conveying device 11 and between the preset feeding device 12 and the fabric receiving device 13 for clamping the preset material roll 3 with the preset material roll end 31, and a clamping device 15 disposed on the conveying device 11 for clamping the preset material roll end 31. The conveying device 11 is provided with a displacement device. The device 111 includes a displacement power unit 112 on each side to drive the displacement device 111 to reciprocate along the direction of the fabric receiving device 13. A fabric receiving conveying device 113 is provided on one side of the displacement device 111 facing the fabric receiving device 13. A first rotary power unit 141 and a second rotary power unit 142 are provided on two opposite sides of the rotary clamping device 14. A mounting device 141 is provided between the first rotary power unit 141 and the second rotary power unit 142. The system includes a support portion 143 for a first rotary power unit 141 and a second rotary power unit 142. A transmission assembly 1431 is provided within the support portion 143 adjacent to the second rotary power unit 142. Clamping portions 144 are respectively provided on two opposite sides, adjacent to the first rotary power unit 141 and adjacent to the second rotary power unit 142. Each clamping portion 144 on the side adjacent to the second rotary power unit 142 is assembled into a linked state via the transmission assembly 1431. The support portion 143... Each adjacent clamping part 144 is provided with a clamping drive unit 145 on one side. The first rotary power unit 141 drives the support part 143 to rotate and the second rotary power unit 142 drives the transmission group in the support part on the side of the second rotary power unit 142 to drive the rotation of each clamping part 144. Then, the clamping drive unit 145 drives each clamping part 144 to clamp the preset material roll 3 to move back and forth. However, the preset material roll 3 can be a cloth roll, fiber roll or flexible circuit board material.

[0049] The fabric end trimming device 2 is mounted on the displacement device 111 of the conveying device 11, and the displacement power unit 112 drives the displacement device 111 to move the fabric end trimming device 2 back and forth. The fabric end trimming device 2 includes a first support frame 21 mounted on the displacement device 111, a pressing device 22 mounted on the first support frame 21, a second support frame 23 mounted on the displacement device 111 and adjacent to the first support frame 21 on one side in the direction of the fabric receiving device 13, a fabric end trimming module 24 mounted on the second support frame 23, and at least one or more preset sensing components 25 mounted on at least one side of the pressing device 22.

[0050] The pressing device 22 of the above-mentioned fabric end trimming device 2 includes a guide group 221 and a pressing group 222. The guide group 221 includes a first guide plate 2211 with a first guide slope 2212 and a second guide plate 2213 with a second guide slope 2214, which are arranged opposite each other on one side of the first support frame 21. An open guide port 2215 is provided between the first guide plate 2211 and the second guide plate 2213 to guide the end 31 of the preset material roll 3 when it is lowered. The pressing group 222 includes two adjacent pressing rods 2221 arranged side by side on one side of the first support frame 21 opposite to the direction of the fabric receiving device 13. The two pressing rods 2221 and the guide port 2215 are connected. The spacing between the two pressure rods 2221 is set as a trimming space 2222, and a cutting space 2223 is provided between the two pressure rods 2221 in an intermittent manner. The two pressure rods 2221 are provided with a plurality of pressure driving units 2224 on the opposite side of the first support frame 21. Each pressure driving unit 2224 drives the two pressure rods 2221 to move back and forth along the direction of the fabric splicing device 13. When the two pressure rods 2221 are displaced, an open pressure space 2225 is formed between the two pressure rods 2221 and the first support frame 21 to allow the preset material roll end 31 to pass through. The two pressure rods 2221 are driven to reset by each pressure driving unit 2224, thereby forming the preset material roll end 31 being pressed at the two pressure rods 2221.

[0051] The fabric end trimming module 24 of the aforementioned fabric end trimming device 2 includes a work platform 241 mounted on the second support frame 23, a moving force unit 242 mounted on one side of the work platform 241 and driving the work platform 241 to move back to its original position along the parallel direction of the holding device 22, a platform driving unit 243 mounted on one side of the work platform 241 and driving the work platform 241 to move back to its original position along the direction of the holding device 22, and adjacent cutting groups 244, tape groups 245, spot welding groups 246, and tape cutting groups 247 mounted on the work platform 241. The work platform 241 is provided with a first support platform 2411 and a second support platform 2412 of different heights to provide trimming space 2222 and cutting space 222 of the holding device 22. 3. The cutting assembly 244 is used and is set on the first support platform 2411. The cutting assembly 244 includes a cutting drive unit 2441 set on the first support platform 2411, a cutting seat 2442 assembled on one side of the cutting drive unit 2441, and a cutter 2443 assembled on one side of the cutting seat 2442. The cutting space 2223 of the cutter 2443 extends out of the outside of the first support platform 2411. The cutting seat 2442 and the cutter 2443 are moved back and forth along the direction of the two pressure rods 2221 by the cutting drive unit 2441, so that the cutter 2443 extends into the cutting space 2223 during displacement to cut the inner surface of the preset material roll end 31 pressed by the two pressure rods 2221 within the cutting space 2223.

[0052] The tape assembly 245 of the aforementioned fabric trimming module 24 includes a take-up wheel 2451, a tape pulley 2452 disposed on one side of the take-up wheel 2451, a tape 2453 sleeved on the tape pulley 2452, a tape power unit 2454 disposed on the opposite side of the second support platform 2412 on the take-up wheel 2451 and the tape pulley 2452, and a roller seat 2455 with a roller 2456 disposed on one side of the take-up wheel 2451. The roller 2456 extends outward from the second support platform 2412 toward the trimming space 2222, and the tape 2453 is sleeved on the tape pulley 2452. One side of the tape 2453 is wound around the roller 2456 and connected to the take-up wheel 2451. The assembly of tape 2453 is completed on 451. After the cutting group 244 completes the cutting operation, when the wheel power unit 2453 is started, it will drive the recycling wheel 2451 to rotate, causing the tape 2453 to generate tape release and recycling tension. In turn, the recycling wheel 2451 pulls the tape 2453 to perform the adhesive film bonding operation. The tape 2453 that has completed the adhesive film bonding operation is also moved to the recycling wheel 2451. When the tape group 245 is moved by the platform drive unit 243, the outer roller 2456 extends into the trimming space 2222 to press the tape 2453 against the preset material roll end 31 of the preset material roll 3 in the trimming space 2222.

[0053] The spot welding assembly 246 includes an abutment drive unit 2461 disposed on the second support platform 2412 facing the trimming space 2222, an abutment member 2462 assembled on one side of the abutment drive unit 2461, a spot welding drive unit 2464 disposed on the second support platform 2412 on one side of the abutment drive unit 2461, and a spot welding member 2465 with a spot welding head 2466 assembled on one side of the spot welding drive unit 2464. The retainer 2462 has through slots 2463 on two opposite sides for the tape 2453 of the tape assembly 245 to pass through, so that the tape 2453 will come off when the recycling wheel 2451 rotates. The adhesive film of the tape 2453 passes through one side of the slot 2463 and exits from the other side, so that the adhesive film of the tape 2453 is properly positioned on the inner surface of the preset roll end 31. Then, the spot welding head 2466 of the spot welding member 2465 is active. The welding head 2466 is positioned so that one end of the welding head 2466 abuts against the inner surface of the preset material roll end 31, thereby actuating the welding drive unit 2464 to guide the other end of the welding head 2466 to abut against the inner surface of the preset material roll end 31. This provides a reliable positioning contact for the welding head 2466 during operation. The abutment 2462 and the welding head 2466 extend outward from the outside of the first support platform 2411 toward the trimming space 2222, causing the platform to... When the drive unit 243 drives the spot welding assembly 246 to move, the outer abutment 2462 and the spot welding head 2466 extend into the trimming space 2222 to abut the adhesive film of the tape 2453 against the inner surface of the preset material roll end 31 in the trimming space 2222 through the abutment 2462, and the spot welding head 2466 generates heat to act on the adhesive film of the tape 2453 to form a heat melt bond to the inner surface of the preset material roll end 31.

[0054] However, the tape cutting assembly 247 includes a tape cutting drive unit 2471 mounted on the second support platform 2412, a tape cutting seat 2472 assembled on one side of the tape cutting drive unit 2471, and a tape cutting blade 2473 assembled on one side of the tape cutting seat 2472. The tape cutting blade 2473 extends outward from the first support platform 2411 toward the trimming space 2222. After the adhesive film of the tape 2453 of the tape assembly 245 is bonded by the spot welding assembly 246, the tape cutting drive unit 2471 will be activated to move back and forth along the trimming space 2222. This causes the tape cutting drive unit 2471 to drive the tape cutting blade 2473 of the tape cutting seat 2472 to extend into the trimming space 2222 to cut the tape 2453 on the inner surface of the preset roll end 31 in the trimming space 2222.

[0055] Furthermore, the displacement power unit 112, the first rotation power unit 141, the second rotation power unit 142 on the aforementioned workbench 1, the movement power unit 242 on the fabric end trimming device 2, and the rubber wheel power unit 2454 can all be power sources such as motors. As for the clamping drive unit 145 on the aforementioned workbench 1, the various pressing drive units 2224 on the fabric end trimming device 2, the platform drive unit 243, the cutting drive unit 2441, the abutment drive unit 2461, and the spot welding unit... The drive unit 2464 and the tape cutting drive unit 2471 can be drive sources such as pneumatic cylinders or hydraulic cylinders, and the transmission group 1431 can be a linkage method such as chain drive or belt drive. However, the preset feeding device 12 can be a preset crane, boom, forklift, mechanical lifting platform or mechanical moving trolley, etc., to provide a device for the rotating clamping device 14 to hold the preset material roll 3. In addition, the cutter 2443 can be a blade, wheel cutter or other type of cutting tool.

[0056] Please refer to the following: Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 The figures show cross-sectional views of the two pressure rods before displacement, cross-sectional views of the two pressure rods after displacement, cross-sectional views of the fabric end trimming module after displacement, flowcharts (I), (II), and (III) of the present invention. As can be clearly seen from the figures, the fabric end trimming device and its method for automated fabric splicing of the present invention include a worktable 1 and a fabric end trimming device 2. The fabric end trimming device 2 performs trimming operations according to the following steps:
