Description

Technical Field

[0001] This utility model relates to the field of tape applicator technology, and in particular to a feeding mechanism for a tape applicator. Background Technology

[0002] In industrial production fields such as electronics and packaging, the feeding mechanism of tape applicators is a key piece of equipment for achieving automatic tape application. It needs to complete the following steps in sequence: tape unwinding, guiding and conveying, workpiece application, release paper winding, and tape cutting. However, existing feeding mechanisms have obvious technical defects. During tape conveying, insufficient guidance can easily cause deviation, resulting in low tape positioning accuracy. Poor compatibility between the conveyor rollers and the material can easily lead to slippage and jamming. The cutting mechanism often uses manual or unstable drive methods, resulting in large cutting position deviations, rough cuts, and inability to quickly reset and connect to the next process after cutting. Furthermore, the release paper winding and tape conveying speeds are difficult to synchronize, which can easily cause entanglement. At the same time, there is a lack of effective monitoring of the material conveying status. When the material is exhausted or broken, the equipment may run idle, which can easily cause malfunctions. The overall level of automation and operating efficiency is difficult to meet the needs of high-efficiency production.

[0003] Therefore, those skilled in the art have provided a feeding mechanism for an adhesive tape applicator to solve the problems mentioned in the background art. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0035] Reference Figure 1-10A feeding mechanism for a tape applicator includes an assembly base plate 1, a feeding tray 2 for winding tape is installed on the upper left side of the assembly base plate 1, a plurality of guide rollers 3 distributed along a preset path for tape conveying are installed on the side of the assembly base plate 1, a winding tray 4 is provided on the lower left side of the assembly base plate 1, the winding tray 4 is used to wind up the release paper peeled off the surface of the tape, and a tape applicator 5 is installed on the lower right side of the assembly base plate 1.

[0036] The adhesive applicator 5 includes a support base 51 fixed to the side of the assembly base plate 1 and horizontally arranged. Movable arms 52 are rotatably mounted on both sides below the support base 51. One end of the two movable arms 52 is connected to the adhesive applicator plate 53. A pressure roller 54 is rotatably mounted on the side of the adhesive applicator plate 53 away from the movable arms 52. A slide rail 55 is provided on the surface of the adhesive applicator plate 53. A knife holder 56 is slidably connected on the slide rail 55. A cutting blade 57 is fixedly connected to the bottom end of the knife holder 56. Synchronous pulleys 58 are rotatably mounted on the surface of the adhesive applicator plate 53 near both ends of the slide rail 55. A synchronous conveyor belt 59 is connected between the two synchronous pulleys 58. The knife holder 56 is fixedly connected to one side of the synchronous conveyor belt 59.

[0037] By adopting the above technical solution, a complete tape conveying and adhesive application system is formed by assembling a base plate 1 to support the feeding tray 2, guide rollers 3, winding tray 4, and adhesive application mechanism 5. The feeding tray 2 provides tape raw materials, multiple guide rollers 3 guide the tape conveying along a preset path, and the winding tray 4 simultaneously winds up the peeled release paper to avoid the release paper tangling and affecting the conveying. In the adhesive application mechanism 5, the support seat 51, movable arm 52, adhesive application plate 53, pressure roller 54, and cutting assembly work together to realize the integrated action of tape application and cutting. The overall structure is compact, ensuring the continuous and efficient operation of tape feeding, adhesive application, cutting, and release paper winding, and greatly improving the automation level of the adhesive application operation.

[0038] The blade holder 56 has an L-shaped structure, including a horizontal section and a vertical section. The horizontal section of the blade holder 56 is slidably connected to the slide rail 55, and its bottom surface is fixed to one side of the synchronous conveyor belt 59. The bottom end of the vertical section of the blade holder 56 is fixed to the cutting blade 57.

[0039] The cutting blade 57 is located in the gap between the pressure roller 54 and the adhesive plate 53, and the cutting blade 57 extends below the adhesive plate 53.

[0040] Using the above technical solution, the L-shaped knife holder 56 is slidably connected to the slide rail 55 and fixedly connected to the synchronous conveyor belt 59 through the horizontal section, and fixedly connected to the cutting blade 57 through the vertical section. This not only ensures the stability of the knife holder sliding, but also achieves the precise installation of the cutting blade. The cutting blade 57 is placed in the gap between the pressure roller 54 and the adhesive plate 53 and extends to the bottom of the adhesive plate, so that the tape can be cut immediately after it is applied. The cutting position is close to the bonding surface, avoiding excess tape length, and does not interfere with the bonding action of the pressure roller 54, thus improving the cutting accuracy and adhesive application integrity.

[0041] A drive motor 510 is vertically mounted on the top surface of the adhesive application plate 53. The adhesive application plate 53 has a cavity inside. The output end of the drive motor 510 and the shaft end of one of the synchronous pulleys 58 are both movably inserted into the cavity and are fixedly connected to a transmission pulley 511. The two transmission pulleys 511 are connected by a transmission belt.

[0042] Using the above technical solution, the drive motor 510 on the top surface of the adhesive plate 53 transmits power to the synchronous pulley 58 through two transmission pulleys 511 and a transmission belt in the cavity, thereby driving the synchronous conveyor belt 59 to drive the cutter holder 56 to slide linearly along the slide rail 55, realizing the cutting action of the cutting blade 57. After cutting, the drive motor 510 flips and drives the synchronous conveyor belt 59 to move in the opposite direction through the same transmission path, so that the cutter holder 56 returns to the initial position, and the cutter holder 56 always maintains linear movement along the slide rail 55 to avoid deviation. The motor drive can precisely control the movement direction and stroke of the cutter holder 56, ensuring accurate cutting position each time and improving the reliability of the cutting action.

[0043] Mounting plates 512 are rotatably mounted on the bottom surface of the support base 51 and the bottom side of the mounting base plate 1. Telescopic cylinders 513 are fixedly connected to the side of the mounting plate 512, and the output ends of the two telescopic cylinders 513 are respectively hinged to the upper surface of the two movable arms 52.

[0044] Using the above technical solution, the bottom surface of the support seat 51 and the mounting plate 512 at the bottom of the mounting base 1 provide a stable mounting foundation for the telescopic cylinder 513. The output end of the telescopic cylinder 513 is hinged to the upper surface of the movable arm 52. The rotation angle of the movable arm 52 can be precisely controlled by the telescopic movement of the cylinder, thereby adjusting the height and bonding angle of the adhesive plate 53 and the pressure roller 54. This design can adapt to workpieces of different thicknesses and shapes. The bonding pressure can be adjusted by the air pressure of the cylinder to ensure that the tape is tightly bonded to the surface of the workpiece and avoid bonding defects such as bubbles and wrinkles.

[0045] A first guide roller 514 is rotatably mounted on the side of the bearing seat 51 away from the pressure roller 54, a second guide roller 515 is rotatably mounted between the two movable arms 52, and a guide groove 516 is opened on the bottom surface of the adhesive plate 53.

[0046] Below the adhesive plate 53 is a movable plate 517, and the top surface of the movable plate 517 is fixed with a push plate 518 that matches the width of the guide groove 516.

[0047] Using the above technical solution, the first guide roller 514 on the bearing seat 51 and the second guide roller 515 between the movable arm 52 form a double guide before the tape enters the adhesive plate 53, ensuring that the tape conveying path is accurate and without deviation; the guide groove 516 on the bottom surface of the adhesive plate 53 is adapted to the push plate 518 on the top surface of the movable plate 517, and the push plate can pre-position and push the tape along the guide groove, so that the tape is kept flat and aligned before bonding, avoiding the deviation of the adhesive bonding position caused by the tape deviation during the conveying process, and significantly improving the positioning accuracy of the adhesive bonding operation.

[0048] Both sides of the adhesive plate 53 are equipped with translation cylinders 519 along its length. The output end of the translation cylinder 519 is vertically fixed to the lifting cylinder 520. The bottom of the output end of the two lifting cylinders 520 is fixed to both sides of the top of the movable plate 517.

[0049] Using the above technical solution, the lifting cylinders 520 and the translation cylinders 519 on both sides of the adhesive application plate 53 work in concert: after the tape is cut, the lifting cylinders 520 drive the movable plate 517 and the push plate 518 to move upwards and press firmly against the tape, preventing the tape from shifting during pushing; then the translation cylinders 519 drive the push plate 518 to move horizontally along the length of the adhesive application plate, accurately pushing the tape below the pressure roller 54, directly connecting to the next adhesive application action, effectively ensuring the continuity of the adhesive application work and reducing process intervals. When the push plate 518 is not pressed firmly against the tape during the adhesive application process, it forms a limiting channel with the guide groove 516 on the bottom surface of the adhesive application plate 53, allowing the tape to pass through stably, ensuring that the tape conveying path does not deviate and does not interfere with the normal adhesion of the tape, further improving the accuracy and smoothness of the adhesive application operation.

[0050] On the side of the assembly base plate 1, on the conveyor belt and release paper conveyor path, there are conveyor roller groups 6. The conveyor roller group 6 includes two parallel and spaced positioning plates 61. One of the positioning plates 61 is fixed on the assembly base plate 1. The conveyor roller 62 and the adjusting roller 63 are installed vertically and parallel between the two positioning plates 61. The four corners of the two adjacent sides of the two positioning plates 61 are connected to the connecting rod 64.

[0051] The adjusting roller 63 has a hollow structure, and a rotating rod 65 is rotatably mounted inside it via bearings. Both ends of the rotating rod 65 extend to the outside of the adjusting roller 63, and eccentric wheels 66 are fitted on both ends of the outside of the rotating rod 65. An eccentric groove coaxial with the rotating rod 65 is opened on the adjacent side of the two positioning plates 61. The two eccentric wheels 66 roll and fit against the inside of the eccentric groove. One end of the rotating rod 65 extends outward through one side of the positioning plate 61 and is fixedly connected to an adjusting knob 67.

[0052] Using the above technical solution, in the conveyor roller assembly 6, two positioning plates 61 are fixed by connecting rods 64 at the four corners, providing a stable mounting frame for the conveyor roller 62 and the adjusting roller 63. By rotating the adjusting knob 67, the rotating rod 65 inside the adjusting roller 63 can be rotated, causing the eccentric wheels 66 at both ends of the rotating rod to roll in the eccentric grooves of the positioning plate 61, thereby flexibly adjusting the distance between the adjusting roller 63 and the conveyor roller 62. This distance adjustment allows both to accurately clamp the passing tape or release paper, ensuring that the conveyor roller 62 can reliably drive the material transmission through friction when rotating, avoiding material slippage and conveying jams. At the same time, it can adapt to tapes or release papers of different thicknesses, ensuring that materials of different specifications can be stably clamped and transmitted, reducing deviation or damage during transmission, and improving the stability and adaptability of material conveying.

[0053] The first rotary motor 7 and the second rotary motor 8 are respectively installed on the upper and lower sides of the side of the assembly base plate 1. The shaft ends of the conveying rollers 62 in the two conveying roller groups 6 are movably extended to the back of the assembly base plate 1, and the shaft ends of the two conveying rollers 62 are respectively connected to the output ends of the first rotary motor 7 and the second rotary motor 8 through the first belt group 9.

[0054] The lower conveyor roller 62 is also connected to the shaft end of the take-up reel 4 via the second belt assembly 10.

[0055] Using the above technical solution, the first rotary motor 7 and the second rotary motor 8 drive the conveyor rollers 62 of the two sets of conveyor roller groups 6 respectively through the first belt group 9. The lower conveyor roller 62 drives the winding reel 4 through the second belt group 10, realizing the power synchronization of tape conveying and release paper winding. The motor drive ensures that the conveying speed of the conveyor roller 62 and the winding speed of the winding reel 4 are precisely matched, avoiding the pulling and breaking caused by the tape being conveyed too fast, the accumulation caused by the tape being conveyed too slowly, or the residual entanglement caused by the release paper not being wound in time, thus greatly improving the overall coordination efficiency of feeding and winding.

[0056] On the side of the assembly substrate 1, detection rollers 11 are installed on the conveying path of the tape and release paper. Guide rails 12 are installed vertically on the upper and lower positions of the side of the assembly substrate 1. A slide block 13 is slidably connected to the side of the guide rail 12, and the slide block 13 is sleeved on one end of the detection roller 11. A guide rod 14 is installed between the upper and lower ends of the side of the guide rail 12. One end of the detection roller 11 and one end of the slide block 13 are slidably sleeved on the outside of the guide rod 14. A contact sensor 15 is installed on the guide rod 14. The two sets of contact sensors 15 are respectively connected to the control terminals of the first rotary motor 7 and the second rotary motor 8.

[0057] Using the above technical solution, the detection roller 11 on the assembly substrate 1 is slidably connected to the guide rail 12 and guide rod 14 via the slide block 13. The tape and release paper pass through the bottom of the corresponding detection roller 11, and the lower detection roller mechanism is symmetrically arranged with the upper one (the sensor is located at the bottom). During normal conveying, the tape side drives the detection roller 11 to move upward along the guide rail 12 due to tension. The slide block 13 moves synchronously with it and contacts the contact sensor 15 on the guide rod 14 (a spring buffer structure is provided at the contact point to avoid damage from hard collisions). The first rotary motor 7 continues to operate normally, while the release paper side supports the detection roller 11 due to tension, preventing it from contacting the bottom. The contact sensor 15 is used, and the second rotary motor 8 is working normally. When the tape is released or breaks, or the release paper can no longer provide support, the corresponding detection roller 11 will slide down the guide rail 12 due to gravity. The tape-side detection roller will detach from the sensor, and the release paper-side detection roller will contact the sensor below. At this time, the contact sensor 15 will send signals to the first rotary motor 7 and the second rotary motor 8 respectively to shut them down, thereby monitoring the material conveying status in real time, avoiding tape application failures caused by equipment idling or material shortage, protecting the equipment and reducing ineffective energy consumption, and improving operational safety and stability. The relevant contact sensing technology is existing technology, so it will not be described in detail.

[0058] Working principle:

[0059] During operation, the tape released from the feeding tray 2 is guided to the conveying roller group 6 by the guide roller 3. Rotating the adjustment knob 67 causes the adjustment roller 63 and the conveying roller 62 to clamp the tape. The first rotary motor 7 and the second rotary motor 8 drive the conveying roller 62 to convey the tape and drive the winding reel 4 to wind up the peeled release paper. The tape enters the adhesive application mechanism 5 through the first guide roller 514 and the second guide roller 515. The lifting cylinder 520 drives the push plate 518 to press the tape tightly. The translation cylinder 519 pushes the tape under the pressure roller 54. The telescopic cylinder 513 adjusts the movable arm 52 to make the pressure roller 54 adhere to the tape. After adhesion, the drive motor 510 drives the knife holder 56 and the cutting blade 57 to cut the tape along the slide rail 55 through the transmission pulley 511 and the synchronous pulley 58. The motor flips to reset the knife holder. The detection roller 11 monitors the material tension throughout the process. When there is an abnormality, the contact sensor 15 controls the corresponding motor to stop, completing the continuous adhesive application operation.

[0060] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
