Description

Technical Field

[0001] This invention relates to the field of tape bonding device technology, specifically to an automatic tape bonding device and bonding process with positioning function. Background Technology

[0002] As production lines become increasingly automated, processing efficiency also increases, and the yield rate of products improves due to reduced manual processing. In the SMT (Surface Mount Technology) field, material strips are often applied manually or semi-mechanically. However, existing equipment cannot accurately position the materials being processed due to their complex and varied dimensions. This can cause the materials to collide with the extrusion components, affecting the processing quality and the lifespan of the equipment itself. Furthermore, prolonged operation of the machinery can lead to fatigue in the transport components, making it difficult to transport the equipment smoothly. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic tape bonding device and bonding process with positioning function to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0005] This invention relates to an automatic tape bonding device and bonding process with positioning function, comprising a housing, the housing including a transport compartment and a positioning compartment, the positioning compartment being fixedly connected above the transport compartment, a motor being fixedly installed on the bottom of the inner wall of the transport compartment, a conveyor belt inside the transport compartment, and a tape box being fixedly connected above the inner wall of the positioning compartment, and further comprising: a positioning mechanism, the positioning mechanism including a positioning component and a pressing roller, the positioning component and the pressing roller being both disposed inside the positioning compartment, the positioning component including a first positioning roller, a second positioning roller and a third positioning roller, and a compensation part, the compensation part including a compensation roller, the compensation roller being disposed between the conveyor belt and the bottom of the inner wall of the transport compartment.

[0006] Furthermore, the conveyor belt has drive wheels at both ends, and both ends of the drive wheels are rotatably connected to the inside of the mounting ring. The mounting ring is fixedly connected to the inner side wall of the transport compartment. The motor output end is driven by a belt, and the motor is driven by a drive wheel through the belt.

[0007] Furthermore, the tape box, positioning component, and extrusion roller are sequentially distributed inside the positioning chamber. U-shaped blocks with upward openings are fixedly connected to the inner walls of both sides of the tape box near the positioning component. Tape is movably connected inside the U-shaped blocks. A long groove is opened at the lower end of the side wall of the tape box near the positioning component. Two small limiting cylinders are rotatably connected up and down to the side of the two sides of the tape box where the U-shaped blocks are fixedly connected. A large limiting cylinder is rotatably connected to the side wall of the tape box between the tape and the small limiting cylinders.

[0008] Furthermore, sleeves are rotatably connected to both ends of the first positioning roller, the second positioning roller, and the third positioning roller. Guide rod one, guide rod two, and guide rod three are respectively fixedly connected to the sleeves located at both ends of the first positioning roller, the second positioning roller, and the third positioning roller. The ends of guide rod one, guide rod two, and guide rod three away from the sleeves are fixedly connected to the same limiting blocks. The limiting blocks located on guide rod one, guide rod two, and guide rod three are respectively slidably connected inside limiting sleeve one, limiting sleeve two, and limiting sleeve three.

[0009] Furthermore, the ends of the first, second, and third limiting cylinders away from the sleeve are all fixedly connected to the inner wall above the positioning chamber, and the ends of the second and third limiting cylinders near the first limiting cylinder are provided with vertical grooves.

[0010] Furthermore, guide rods are fixedly connected to the side of the first positioning roller and the second positioning roller that is close to the third positioning roller. The end of the guide rod on the first positioning roller that is away from the sleeve passes through the vertical groove on the second limiting cylinder and is rotatably connected to the groove on the limiting block. The end of the guide rod on the second positioning roller that is away from the sleeve passes through the vertical groove on the third limiting cylinder and is rotatably connected to the groove on the limiting block.

[0011] Furthermore, guide plates one, two, and three are rotatably connected to both ends of the first, second, and third positioning rollers, respectively. Guide plates two and three each have identical slots. Protruding posts are fixedly connected to the sides of guide plates one and two that are furthest from the sleeve, respectively. These protruding posts on guide plates one and two are slidably connected to the slots on guide plates two and three. A square plate is fixedly connected between the two guide plates three, and a tension spring is fixedly connected between the square plate and the upper wall of the positioning chamber.

[0012] Furthermore, the extrusion roller is rotatably connected to a set of fixed plates. Two guide columns are fixedly connected to the side of the fixed plates away from the extrusion roller. The end of the guide column away from the extrusion roller slides through the guide block and is fixedly connected to the same cylinder. The end of the guide plate away from the sleeve is rotatably connected to the cylinder. The guide block is fixedly installed between the two side walls of the positioning chamber by the fixed columns fixedly connected at both ends.

[0013] The fixed plate is rotatably mounted on two square blocks at its two ends via fixed connections. A rack parallel to the guide column is engaged with the side of the gear away from the extrusion roller. The rack is fixedly connected to the side wall of the positioning chamber via a receiving plate on its back. A blade is fixedly connected through the square blocks on the side of the two gears that are close to each other.

[0014] Furthermore, the compensating roller is rotatably connected between a pair of actuating rods, and the two actuating rods are slidably connected to a crossbar through a groove formed thereon. The end of the actuating rod away from the compensating roller is rotatably connected between a pair of protruding plates fixedly connected to the inner wall below the transport compartment. Three push rods are rotatably connected to the crossbar. The end of the push rod away from the crossbar is slidably connected to the inside of a column fixedly connected to the inner wall below the transport compartment. A compensating spring is provided between the push rod and the bottom of the inner wall of the column.

[0015] An automatic tape bonding device with positioning function includes the following steps in its bonding process:

[0016] Step 1: The motor operates to place the material to be processed above the conveyor belt. The motor drives the conveyor belt to rotate and transport the material to be processed to the area below the positioning component. The state of the extrusion rollers is adjusted according to the size of the material to be processed.

[0017] Step 2: The material to be processed touches the first positioning roller, which is squeezed and moves upward. The sleeve moves synchronously with the first positioning roller, pushing the first guide rod to move upward. At the same time, the guide rod pushes the second guide rod to move upward, causing the second positioning roller to move upward with the first positioning roller. The first guide plate rotates, pushing the upper end of the second guide plate to slide upward, and pushing the third guide plate to slide upward.

[0018] Step 3: The material to be processed touches the second positioning roller, and the second positioning roller is squeezed and moves upward. The sleeve moves synchronously with the second positioning roller, pushing the second guide rod to move upward. At the same time, the guide rod pushes the third guide rod to move upward, so that the third positioning roller moves upward with the second positioning roller. The second guide plate rotates, pushing the upper end of the third guide plate to slide upward, thereby indirectly pushing the guide column to slide upward, driving the extrusion roller to move upward.

[0019] Step four: The material being processed touches the third positioning roller, which is then squeezed and moves upward. The sleeve moves synchronously with the third positioning roller, pushing the guide rod three upward. The guide plate three rotates, pushing the guide column to slide upward, which in turn drives the extrusion roller to move upward. At the same time, the blade moves synchronously with the extrusion roller, performing lifting and cutting actions.

[0020] (1) By setting up the positioning components, when the material to be processed is transported into the positioning chamber, the material to be processed will touch the first positioning roller, the second positioning roller or the third positioning roller. The height of the extrusion roller is adjusted according to the size of the material to be processed, so as to avoid the material to be processed being too thick and colliding with the extrusion roller, which would affect the service life of the device and the quality of the finished product.

[0021] (2) By setting the extrusion roller, the height of the extrusion roller will change according to the different materials to be processed, ensuring the smooth progress of the processing action and ensuring the tight adhesion between the tape and the material to be processed. While the extrusion roller rises, the blade moves upward, which can avoid the blade from contacting the surface of the material to be processed during transportation and affecting the processing quality. When the material to be processed leaves the extrusion roller, the positioning mechanism resets, the blade follows the gear to rotate and falls, and cuts the tape.

[0022] (3) By setting up the compensating roller, when the conveyor belt becomes loose due to prolonged use, the compensating spring extends and, through the action of the push rod, cross rod, and actuating rod, the compensating roller squeezes the conveyor belt, keeping the conveyor belt in a taut state. This ensures that the materials to be processed are transported stably on the conveyor belt, guarantees the processing quality of the products, and increases the practicality of the device.

[0023] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0038] Each end of the first positioning roller 31, the second positioning roller 32, and the third positioning roller 33 is rotatably connected to a sleeve 34. Guide rod 1 341, guide rod 2 342, and guide rod 343 are fixedly connected to the sleeves 34 at both ends of the first positioning roller 31, the second positioning roller 32, and the third positioning roller 33, respectively. The ends of the guide rods 1 341, the second guide rod 2 342, and the third guide rod 343 away from the sleeves 34 are fixedly connected to the same limiting blocks 35. The limiting blocks 35 on the guide rods 1 341, the second guide rod 2 342, and the third guide rod 343 are slidably connected inside the limiting sleeves 1 351, the second limiting sleeve 2 352, and the third limiting sleeve 353, respectively. The purpose of this arrangement is to facilitate the fixing of the first positioning roller 31, the second positioning roller 32, and the third positioning roller 33 and to facilitate their up and down sliding.

[0039] The ends of limiting cylinder 1 351, limiting cylinder 2 352 and limiting cylinder 353 away from sleeve 34 are all fixedly connected to the inner wall above positioning chamber 2. The ends of limiting cylinder 2 352 and limiting cylinder 353 near limiting cylinder 1 351 are provided with vertical grooves 354.

[0041] The first positioning roller 31, the second positioning roller 32, and the third positioning roller 33 are rotatably connected at both ends to guide plate 1 37, guide plate 2 38, and guide plate 39, respectively. Guide plate 2 38 and guide plate 39 are both provided with the same slot 391. The sides of guide plate 1 37 and guide plate 2 38 that are away from the sleeve 34 are fixedly connected to each other with protrusions 392. The protrusions 392 on guide plate 1 37 and guide plate 2 38 are slidably connected to the slots 391 on guide plate 2 38 and guide plate 39, respectively. The purpose of this arrangement is to facilitate the movement of guide plate 2 38 and guide plate 39 while guide plate 1 37 and guide plate 2 38 are moving.

The purpose of this arrangement is to facilitate the positioning mechanism's position and reset.

[0042] The extrusion roller 4 is rotatably connected to a set of fixed plates 41. Two guide columns 42 are fixedly connected to the side of the fixed plates 41 away from the extrusion roller 4. The end of the guide column 42 away from the extrusion roller 4 slides through the guide block 43 and is fixedly connected to the same cylinder 44. The end of the guide plate 39 away from the sleeve 34 is rotatably connected to the cylinder 44. The guide block 43 is fixedly installed between the two side walls of the positioning chamber 2 by the fixed columns 431 fixedly connected at both ends. The purpose of this arrangement is to facilitate the extrusion roller 4 to slide up and down along the guide column 42.

[0043] The fixed plate 41 is rotatably mounted on two blocks 45 at its two ends via a fixed connection. A rack 46 parallel to the guide post 42 is meshed on the side of the gear 451 away from the extrusion roller 4. The rack 46 is fixedly connected to the side wall of the positioning chamber 2 via a receiving plate 461 on its back. A blade 47 is fixedly connected to the side of the two gears 451 that are close to each other through the blocks 45.

[0044] The compensating roller 5 is rotatably connected between a pair of actuating rods 51. The two actuating rods 51 are slidably connected to a crossbar 52 through a groove 511. The end of the actuating rod 51 away from the compensating roller 5 is rotatably connected between a pair of protruding plates 512 fixedly connected to the inner wall below the transport chamber 1. Three push rods 53 are rotatably connected to the crossbar 52. The end of the push rod 53 away from the crossbar 52 is slidably connected to the inside of a column 54 fixedly connected to the inner wall below the transport chamber 1. A compensating spring 55 is provided between the push rod 53 and the bottom of the inner wall of the column 54. The purpose of this arrangement is to ensure that the conveyor belt 12 is always taut, which facilitates the smooth transport of the material to be processed.

[0045] When in use, start the motor 11, place the material to be processed on the conveyor belt 12, and the motor 11 drives the conveyor belt 12 to rotate and transport the material to be processed. Due to the different models and thicknesses of the material to be processed, the material to be processed will touch the first positioning roller 31, the second positioning roller 32 or the third positioning roller 33 during the transportation process.

[0046] When the material to be processed can only touch the third positioning roller 33, the third positioning roller 33 is squeezed and moves upward. The sleeve 34 moves synchronously with the third positioning roller 33, pushing the guide rod 343 to move upward. The guide plate 39 rotates and pushes the guide column 42 to slide upward, thereby driving the extrusion roller 4 to move upward, preventing the material to be processed from colliding with the extrusion roller 4, which would affect the service life of the device and the quality of the finished product.

[0047] When the material to be processed can touch the second positioning roller 32, the second positioning roller 32 is squeezed and moves upward. The sleeve 34 moves synchronously with the second positioning roller 32, pushing the second guide rod 342 to move upward. At the same time, the guide rod 36 pushes the third guide rod 343 to move upward, so that the third positioning roller 33 moves upward with the second positioning roller 32. The second guide plate 38 rotates, pushing the upper end of the third guide plate 39 to slide upward, thereby indirectly pushing the guide column 42 to slide upward, and then driving the extrusion roller 4 to move upward. After that, the material to be processed will contact the third positioning roller 33, and the above action is repeated.

[0048] When the material to be processed can touch the first positioning roller 31, the first positioning roller 31 is squeezed and moves upward. The sleeve 34 moves synchronously with the first positioning roller 31, pushing the guide rod 1 341 to move upward. At the same time, the guide rod 36 pushes the guide rod 2 342 to move upward, so that the second positioning roller 32 moves upward with the first positioning roller 31. The guide plate 1 37 rotates, pushing the upper end of the guide plate 2 38 to slide upward, thereby indirectly pushing the guide plate 3 39 to slide upward. Then the material to be processed will come into contact with the second positioning roller 32, and the above two steps are repeated.

[0049] Therefore, based on the size of the material to be processed, the height of the extrusion roller 4 can be adjusted in real time through the setting of the positioning mechanism to ensure the smooth progress of the processing action and to ensure the tight fit between the tape and the material to be processed. As the extrusion roller 4 rises, the gear 451 moves synchronously with it and rotates along the rack 46, which can avoid the blade from contacting the surface of the material to be processed during transportation, thus affecting the processing quality. When the material to be processed leaves the extrusion roller 4, the positioning mechanism resets, and the blade rotates with the gear 451 and falls to cut the tape.

[0050] During transportation, if the conveyor belt 12 becomes loose due to prolonged use, the compensating spring 55 extends and pushes the crossbar 52 upward via the push rod 53. The crossbar 52 slides inside the slide groove 511, causing the actuating rod 51 to rotate, which in turn pushes the compensating roller 5 to compress the conveyor belt 12, keeping the conveyor belt 12 in a taut state. This ensures stable transportation of the materials to be processed on the conveyor belt 12, guarantees the processing quality of the products, and increases the practicality of the device. Example

[0051] Step 1: The motor 11 operates to place the material to be processed above the conveyor belt 12. The motor 11 drives the conveyor belt 12 to rotate and transport the material to be processed to the position component 3. The state of the extrusion roller 4 is adjusted according to the size of the material to be processed.

[0052] Step 2: The material to be processed touches the first positioning roller 31, and the first positioning roller 31 is squeezed and moves upward. The sleeve 34 moves synchronously with the first positioning roller 31, pushing the guide rod 1 341 to move upward. At the same time, the guide rod 36 pushes the guide rod 2 342 to move upward, so that the second positioning roller 32 moves upward with the first positioning roller 31. The guide plate 1 37 rotates, pushing the upper end of the guide plate 2 38 to slide upward, and pushing the guide plate 3 39 to slide upward.

[0053] Step 3: The material to be processed touches the second positioning roller 32, and the second positioning roller 32 is squeezed and moves upward. The sleeve 34 moves synchronously with the second positioning roller 32, pushing the second guide rod 342 to move upward. At the same time, the guide rod 36 pushes the third guide rod 343 to move upward, so that the third positioning roller 33 moves upward with the second positioning roller 32. The second guide plate 38 rotates, pushing the upper end of the third guide plate 39 to slide upward, thereby indirectly pushing the guide column 42 to slide upward, driving the extrusion roller 4 to move upward.

[0054] Step four: The processing material touches the third positioning roller 33, which is squeezed and moves upward. The sleeve 34 moves synchronously with the third positioning roller 33, pushing the guide rod 343 to move upward. The guide plate 39 rotates, pushing the guide column 42 to slide upward, which drives the extrusion roller 4 to move upward. At the same time, the blade 47 moves synchronously with the extrusion roller 4 to perform lifting and cutting actions.
