Description

Technical Field

[0001] The utility model relates to the field of automobile seat heating pad processing, in particular to an adhesive tape pasting mechanism for automobile seat heating pads. Background Art

[0002] In the production process of car seat heating pads, it is necessary to apply adhesive to the surface of the base fabric with the heating wire. Due to the different types of heating pads to be produced, the size of the tape to be applied is also different.

[0003] In the prior art, a tape cutting device is often required to cut tapes of different lengths, and the cut tapes are sent to the pasting position through an adsorption mechanism, and the tapes are tightly pressed onto the base cloth of the heating pad through a clamping device. However, the existing adsorption mechanism has a relatively fixed structure and can only adsorb tapes within a specific length range. When the required length of the tape is too long, the cut tapes will fall down on both sides, and the tape will become uneven when the adsorption mechanism places the tape on the base cloth, which ultimately leads to a poor pasting effect. When the required length of the tape is too short, the adsorption mechanism cannot adsorb the tape. Therefore, the current adsorption mechanism has poor adaptability to tapes of different lengths.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the utility model, and cannot be understood as limitations on the utility model.

[0042] like Figure 1 As shown, an embodiment of the automatic cutting and pasting tape mechanism is used to cut the tape 500 and paste it on the base cloth 510, including a workbench 1, two fixed-length tape supply mechanisms 2 fixed on both sides of the workbench 1, a suction device 3 located above the workbench 1, and a pressing device 4 located at one end of the workbench 1. The controller controls the workbench 1 to drive the base cloth 510 to move to the pasting area along the direction of the arrow in the figure. After the fixed-length tape supply mechanism 2 produces a certain length of tape 500, it is transferred from the fixed-length tape supply mechanism 2 to the base cloth 510 by the suction device 3. Then, the base cloth 510 with the tape 500 pasted on the surface continues to move to the pressing device 4, and the pressing device 4 presses the tape 500 on its surface. Optionally, in other embodiments, the number and position of the fixed-length tape supply mechanism 2 and the suction device 3 can be adjusted as needed.

[0043] like Figure 2 As shown, the fixed-length tape supply mechanism 2 includes a frame 210, a feeding assembly 220, a steering assembly 230, a fixing assembly 240, a cutting assembly 250, a pulling assembly 260, and a solenoid valve assembly 270. The feeding assembly 220, the steering assembly 230, the fixing assembly 240, the cutting assembly 250, the pulling assembly 260, and the solenoid valve assembly 270 are all fixed to the frame 210 by screws or other fasteners.

[0044] The frame 210 includes a box body 211, a first slide rail 212, a mounting plate 213 and a drag chain 214. The box body 211 is fixedly mounted on the first slide rail 212 and can move freely on the first slide rail 212. The first slide rail 212 is fixed to the mounting plate 213 by screws, and the mounting plate 213 is arranged on the side of the workbench 1. The first bottom plate 216 of the box body 211 is provided with an entrance groove 215 on the feeding side, and the tape 500 can enter the steering assembly 230 from the entrance groove 215 during the pulling process. One side of the box body 211 is fixedly connected to the drag chain 214, and the cables and air pipes required for the fixed-length tape supply mechanism 2 are arranged inside the drag chain 214. When the material tray of the tape 500 needs to be replaced, the entire fixed-length tape supply mechanism 2 can be pulled out from the side of the production line for replacement operation by simply pushing the box body 211.

[0045] The feeding assembly 220 includes a feeding roller 221 and a roller base 222. The material tray of the adhesive tape 500 is sleeved on the outside of the feeding roller 221, and the shaft of the feeding roller 221 is passed through the roller base 222 and can rotate freely in the roller base 222. The roller base 222 is fixedly connected to the bottom surface of the box body 211 by screws.

[0046] The pulling assembly 260 includes a pair of fifth cylinders 261, a pair of pulling jaws 262, and a uniaxial motion module 263. The pair of pulling jaws 262 are fixed to the pair of fifth cylinders 261 by fasteners such as screws, and are clamped and loosened under the extension and contraction drive of the fifth cylinders 261. The pair of fifth cylinders 261 are fixed to the uniaxial motion module 263 by screws, and reciprocate under the drive of the uniaxial motion module 263. The uniaxial motion module 263 is fixed to the first bottom plate 216 of the box body 211 by screws. Before cutting the tape 500, the clamping jaws 262 are first driven by the clamping jaw cylinder 261 to clamp the free end of the tape 500, and then the uniaxial motion module 263 drives the entire pulling assembly 260 to move a certain distance. Therefore, controlling the moving distance of the uniaxial motion module 263 can control the length of the tape 500 to be cut.

[0047] The solenoid valve assembly 270 includes a plurality of solenoid valves for controlling the related cylinders in the fixing assembly 240, the cutting assembly 250, and the pulling assembly 260. This is the prior art and will not be described in detail.

[0048] like Figure 3 and Figure 4As shown, the steering assembly 230 includes a roller support 231, a first positioning roller 232, a second positioning roller 233 and a third positioning roller 234. The roller support 231 is fixed near the inlet slot 215 on the first bottom plate 216 of the box body 211 by screws. The first positioning roller 232, the second positioning roller 233 and the third positioning roller 234 are installed on the side of the roller support 231 opposite to the inlet slot 215 by screws or assembly. The roller support 231 also includes a third bottom plate 237, and the third bottom plate 237 is provided with a through hole 236 for the adhesive tape 500 to pass through, and the first clamping plate 244 can clamp the adhesive tape 500 with the upper bottom surface of the through hole 236. At least one positioning block 235 for limiting the axial movement of the adhesive tape 500 is also installed on the first positioning roller 232, and the position of the positioning block 235 can be adjusted according to the width of the adhesive tape 500.

[0049] Further references Figure 4 The fixing assembly 240 includes a first cylinder 241, a second cylinder 242, a pair of third cylinders 243, a first clamping plate 244, a second clamping plate 245 and a third clamping plate 246. The first cylinder 241 is fixed to the bottom surface of the through hole 236 opened on the roller bracket 231 by screws, the second cylinder 242 is fixed to the first bottom plate 216 by screws, and the pair of third cylinders 243 are fixed to the side of the roller bracket 231 away from the inlet groove 215 by screws. The first clamping plate 244 and the second clamping plate 245 are respectively fixed to the movable end covers of the first cylinder 241 and the second cylinder 242 by screws, and the two ends of the third clamping plate 246 are respectively connected to the movable end covers of the pair of third cylinders 243 by fixing. Due to the height difference between the first cylinder 241, the second cylinder 242 and the pair of third cylinders 243, when the adhesive tape 500 passes through the through hole 236, the first clamping plate 244 and the second clamping plate 245 respectively form a clamping area between the third clamping plates 246. In addition, when the first cylinder 241 is extended, the first clamping plate 244 can clamp the adhesive tape 500 with the upper bottom surface of the through hole 236. Further, the second clamping plate 245 is provided with a first cutting groove 247, and the third clamping plate 246 is provided with a second cutting groove 248 corresponding to the first cutting groove 247, and the cutting blade 252 passes through the second cutting groove 248 and the first cutting groove 247 in sequence and can move along the direction of the first cutting groove 247 and the second cutting groove 248.

[0050] The cutting assembly 250 includes a fourth cylinder 251, a cutting blade 252, a pair of first fixing members 253 and a sliding assembly 254. The pair of first fixing members 253 are fixed to the third clamping plate 246 by screws, the two ends of the fourth cylinder 251 are respectively connected with the pair of first fixing members 253, the sliding assembly 254 is fixed to the third clamping plate 246 by screws and is fixedly connected to the fourth cylinder 251, and the cutting blade 252 is fixed to the side of the fourth cylinder 251 by screws. In this embodiment, the fourth cylinder 251 is a rodless cylinder, and the cylinder body can reciprocate with the piston, thereby driving the cutting blade 252 to freely move the cutting tape 500 in the first cutting groove 247 and the second cutting groove 248. The sliding assembly 254 fixed below the fourth cylinder 251 prevents the piston of the fourth cylinder 251 from bending due to the force of the cutting blade 252, thereby ensuring smooth movement.

[0051] The first positioning roller 232 , the first clamping plate 244 , the second clamping plate 245 and the pulling clamping jaw 262 are all fixed with anti-sticking tapes, so as to facilitate the separation of the adhesive surface of the tape 500 from the corresponding contact position without affecting the stickiness.

[0052] like Figure 5 and Figure 6 As shown, the suction device 3 is fixed to a steel bracket (not shown in the figure) installed above the fixed-length tape supply mechanism 2 by bolts and nuts. The suction device 3 includes a three-axis motion module 31 and an adsorption component 32. The three-axis motion module 31 includes an X-motion axis 311, a Y-motion axis 312 and a Z-motion axis 313 that are installed vertically to each other and can move relative to each other. The lower end of the Z-motion axis 313 includes a rotating device 314, and the adsorption component 32 is fixedly connected to the rotating device 314 by screws. Optionally, the rotating device 314 can be a rotating cylinder or an electric rotating disk with a deceleration system. In addition, the suction device 3 also includes a vacuum component 33 fixed on the Z-motion axis 313, which includes a vacuum generator and a plurality of vacuum solenoid valves for providing vacuum suction to the adsorption component 32. This is a prior art, so its detailed structure will not be described in detail.

[0053] like Figure 7 and Figure 8As shown, the adsorption assembly 32 includes a second bottom plate 320, a steering gear 322, a synchronous belt 323, a pair of synchronous wheels 324, a pair of slide plates 325, a pair of first brackets 327, a second slide rail 328 and at least one suction cup 329. A pair of synchronous wheels 324 are symmetrically arranged on the second bottom plate 320, and the synchronous belt 323 is sleeved on the outer periphery of the synchronous wheels 324. In this embodiment, the areas where the synchronous belt 323 and the synchronous wheels 324 contact each other are respectively provided with mutually meshing transmission teeth. The second bottom plate 320 is provided with a side plate 321 protruding from one of the synchronous wheels 324, and the steering gear 322 is fixed to the side plate 321 by screws and connected to the wheel axle of the synchronous wheel 324, so as to drive the synchronous wheel 324 to rotate. A pair of slide plates 325 are fixedly connected to the synchronous belt 323 symmetrically about the geometric center of the bottom plate. Specifically, one end of the slide plate 325 is closely attached to the outer side of the synchronous belt 323, and is fixed to the fixing plate 326 located on the inner side of the synchronous belt 323 by screws. The other end of the slide plate 325 is fixedly connected to the pair of first brackets 327 by welding or other methods. The second slide rail 328 is fixed to the bottom surface of the second bottom plate 320 , and one end of the pair of first brackets 327 is mounted on the second slide rail 328 .

[0054] A pair of guide grooves 340 are also provided on the second bottom plate 320. When the pitch needs to be changed, the servo 322 drives the synchronous wheel 324 to rotate, and the synchronous wheel 324 drives the synchronous belt 323 to rotate through the transmission gear, thereby driving the slide plate 325 fixed on the synchronous belt 323 to move along the direction of the guide groove 340, and the slide plate 325 drives the first bracket 327 to move along the second slide rail 328. Figure 7 As shown, when the synchronous belt 323 rotates in the direction of the solid arrow in the figure, the relative distance between the pair of slide plates 325 is reduced, and the pair of first brackets 327 are close to each other on the second slide rail 328; similarly. When the synchronous belt 323 rotates in the direction of the dotted arrow in the figure, the pair of first brackets 327 are away from each other on the second slide rail 328, thereby achieving a variable distance effect. Optionally, the slide plate 325 and the first bracket 327 can be an integrally formed structure.

[0055] like Fig. 9As shown, the clamping device 4 includes a pressing plate 40 and a pair of sixth cylinders 41. The pair of sixth cylinders 41 are fixed on both sides of the workbench 1 by screws or other fasteners, and the pressing plate 40 is located above the workbench 1 and is fixedly connected to the sixth cylinder 41 by screws. The pressing plate 40 includes a fourth bottom plate 401, a pad 402 and at least one guide rod 403. At least one guide hole 404 is provided on the fourth bottom plate 401, and a limit plate 406 is fixed symmetrically to the side of the fourth bottom plate 401 relative to the workbench 1. The two ends of the fourth bottom plate 401 are fixedly connected to the pair of sixth cylinders 41 by screws or other fasteners. The pad 402 is fixedly connected to at least one guide rod 403, and the guide rod 403 is inserted into the guide hole 404. In this embodiment, a guide hole 404 is provided at each of the four corners of the fourth bottom plate 401, and four guide rods 403 are fixed to the pad 402 at relative positions, and a limit plate 405 is fixed at one end of each guide rod 403 by threading or welding. In this embodiment, in order to reduce the impact of the pressing plate 40 on the product during pressing, a foamed silicone sheet is attached to the side of the pad 402 that contacts the product. The movement of the pair of sixth cylinders 41 is also controlled by a second solenoid valve 411 (not shown in the figure) fixed near the pressing device 4. The relevant structure of the second solenoid valve 411 belongs to the prior art, so it will not be described in detail.

[0056] like Fig.10 As shown, the embodiment of the tape sticking mechanism further includes a controller 6 located in the electric control box. The controller 6 is electrically connected to the single-axis motion module 263, the solenoid valve assembly 270, the three-axis motion module 31, the steering gear 322, the vacuum assembly 33, the second solenoid valve 411 and the workbench 1, and the controller controls the activities of the above components through electrical signals. Preferably, the controller type in this embodiment is PLC.

[0057] When the tape sticking mechanism of the first embodiment is working, the workbench 1 moves the base fabric 510 along the Figure 1 In the fixed-length tape supply mechanism 2, after the free end of the tape 500 is pulled out from the feeding assembly 220, it is successively turned and tensioned by the turning assembly 230, fixed by the fixing assembly 240, and finally cut by the cutting assembly 250 under the pulling of the pulling assembly 260.

[0058] Before the tape 500 is cut, the staff first pulls the free end of the tape 500 out of the feeding assembly 220, passes through the first positioning roller 232, the second positioning roller 233 and the third positioning roller 234 in sequence, and finally clamps it between the first clamping plate 244 and the upper bottom surface of the through hole 236. Before the pulling process starts, the controller controls the first cylinder 241 to extend, the second cylinder 242 to contract, and the third cylinder 243 to extend, and the free end of the tape 500 is clamped by the first clamping plate 244 and the upper bottom edge of the through hole 236 and exposes a certain pulling length. At this time, the end cover of the fifth cylinder 261 extends, so that the pulling clamp 262 remains in an open state. The controller controls the single-axis motion module 263 to drive the fifth cylinder 261 and the pulling clamp 262 to move to the fixed assembly 240, and at this time the pulling clamp 262 can just extend into the area between the second clamp 245 and the third clamp 246. The fifth cylinder 261 contracts to drive the pulling clamp 262 to fit, clamping the free end of the tape 500. Then the first cylinder 241 retracts to release the tape 500. Then the single-axis motion module 263 drives the fifth cylinder 261 and the pulling clamp 262 away from the fixing assembly 240, driving the free end of the tape 500 to be pulled a corresponding distance.

[0059] When the tape 500 is pulled out to the set length, the single-axis motion module 263 stops moving. Then the controller controls the second cylinder 242 to extend and the third cylinder 243 to retract, so that the other end of the tape 500 is clamped by the first clamp 244, the second clamp 245 and the third clamp 246, and at the same time the cutting blade 252 fixed on the fourth cylinder 251 pierces the cutting area of ​​the tape 500. Then the controller controls the fourth cylinder 251 to reciprocate once, driving the cutting blade 252 to cut the tape 500. Finally, the first cylinder 241 extends and re-clamps the newly cut free end of the tape 500 to prevent the tape 500 from returning to the feeding assembly 220 due to inertia and waiting for the pulling step before the next cutting. The fifth cylinder 261 and the second cylinder 242 resume the extended state to loosen the two ends of the cut tape 500, so that it is easy to be taken by the suction device 3.

[0060] After the tape 500 is cut, the adsorption component 32 moves to the top of the fixed-length tape supply mechanism 2 under the drive of the three-axis motion module 31, and then the controller 6 controls the Z motion axis 313 to move downward. At the same time, the controller 6 sends a signal to control the steering engine 322 to drive a pair of first brackets 327 of the adsorption component 32 to open a distance corresponding to the length of the tape 500. When the suction cup 329 gently sticks to the back of the tape 500, the controller 6 controls the vacuum component 33 to generate vacuum suction, and the suction cup 329 adsorbs the tape 500 to be taken. In this embodiment, there are three pairs of suction cups 329 on the adsorption component 32, and each pair of suction cups 329 has its own independent vacuum air path, which can adapt to tapes 500 of different widths. When the tape 500 is completely adsorbed, the three-axis motion module 31 drives the adsorption component 32 to move to the area where it needs to be pasted, and the tape 500 is pasted on the surface of the base cloth 510. Finally, the vacuum component 33 blows air in the opposite direction to help the tape 500 detach from the suction cup 329. The workbench 1 drives the base cloth 510 with the adhesive tape 500 attached thereto to continue moving toward the pressing device 4 .

[0061] When no product passes through the area between the pressing plate 40 and the workbench 1, the piston of the sixth cylinder 41 extends to lift the fourth bottom plate 401. Due to the existence of the guide rod 403 and the limit plate 405, the pad 402 will also be lifted together, so that the pad 402 is separated from the workbench 1. When the base cloth 510 with the tape 500 reaches the pressing area below the pad 402, the piston of the sixth cylinder 41 retracts, driving the fourth bottom plate 401 to move downward until the pad 402 below presses the product. Then the sixth cylinder 41 continues to shrink, and the fourth bottom plate 401 continues to apply positive pressure under the limit of the guide rod 403. When the limit plate 406 below the fourth bottom plate 401 presses against the platform below the workbench 1, the fourth bottom plate 401 cannot move downward any further, and the pressing process ends. Finally, the piston of the sixth cylinder 41 extends, driving the entire pressing plate 40 to leave the workbench 1, waiting for the next pressing operation.

[0062] The automatic tape cutting and pasting mechanism can obtain tapes 500 of different lengths in batches by providing a fixed-length tape supply mechanism 2 and a suction device 3, and transfer and paste the tapes to a designated position. Furthermore, by providing a pressing device 4 on the workbench 1, the tape 500 can be more firmly pasted on the product surface, preventing the tape 500 from falling off later and affecting product quality.

[0063] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
