Description

Technical Field

[0001] This utility model relates to the field of bonding technology, specifically to a high-efficiency pressure-holding dispensing bonding device. Background Technology

[0002] In electronic product manufacturing, some components require pressure holding after dispensing to prevent deformation. However, pressure holding requires specialized fixtures, and these fixtures are not interchangeable between different products. Therefore, a dispensing and pressure holding device that can meet the needs of micro-components is needed.

[0003] As disclosed in Chinese Patent CN213825619U, a dispensing and pressure-holding device has a mold slot on the base. A pre-designed mold can be placed in the slot. The mold has a pressure plate. A stepper motor drives the lowering platform to move along the sliding column. When the ejector pin acts on the pressure plate, pressure is maintained. The headphone shell pressure-holding device has a groove that fits the headphone shell. The headphone shell is placed in the groove first, then dispensing is performed, and then pressure is maintained.

[0004] However, the pressure-holding device's lowering platform is located above the pressure-holding mold. As a result, when dispensing glue onto the earphone shell in the pressure-holding mold, the lowering platform above it will create some obstruction, making it impossible to efficiently dispense glue onto the earphone shell in the pressure-holding mold.

[0005] Therefore, we urgently need to provide a high-efficiency pressure-holding dispensing bonding device that does not interfere with the dispensing of earphone shells in the pressure-holding mold. Utility Model Content

[0006] The purpose of this invention is to provide a high-efficiency pressure-holding dispensing and bonding device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency pressure-holding adhesive bonding device, comprising a base and a left support plate, wherein the left support plate is fixedly connected to the upper left end of the base, a right support plate is fixedly connected to the upper right end of the base, a top plate is connected to the upper sides of the left and right support plates, and a bonding mechanism is connected to the upper end of the base.

[0008] The fitting mechanism includes a pressure-holding base connected to the upper end of the base, a pressure-holding plate connected to the upper side of the pressure-holding base, positioning posts fixedly connected to the four corners of the lower side of the pressure-holding plate, a fixing plate connected to the middle position inside the top plate, a first threaded rod connected to the middle position of the fixing plate, a limit ring fixedly connected to the outer side of the lower end of the first threaded rod, a first handle welded to the upper end of the first threaded rod, limit rods fixedly connected to the left and right ends of the upper side of the fixing plate, a baffle welded to the upper side of the limit rod, an adjusting plate connected to the outer end of the first threaded rod, springs fixedly connected to the four corners of the lower side of the adjusting plate, a pressure plate fixedly connected to the lower end of the springs, and a second threaded rod connected to the middle position of the right end inside the top plate, a second handle welded to the upper end of the second threaded rod.

[0009] A further improvement is that a rectangular groove is provided at the middle position of the upper side of the base, the outer side of the lower end of the pressure-holding base is slidably connected to the inner side of the rectangular groove, a placement groove is provided at the middle position of the upper end of the pressure-holding base, and the earphone shell to be fitted is placed in the placement groove. Positioning grooves are provided at the four corners of the upper side of the pressure-holding base, the upper side of the pressure-holding base abuts against the lower side of the pressure-holding plate, and the outer side of the positioning post is slidably connected to the inner side of the positioning groove. Thus, when the pressure-holding plate is placed on the upper side of the pressure-holding base for pressure holding, the positioning post on the lower side of the pressure-holding plate slides into the positioning groove inside the pressure-holding base, which allows the pressure-holding plate to be accurately installed on the upper end of the pressure-holding base to hold pressure on the earphone shell in the pressure-holding base.

[0010] A further improvement is that a through groove is provided in the middle of the top plate, and the left and right sides of the fixed plate are fixedly connected to the left and right ends of the through groove. Limiting holes are provided in the left and right ends of the adjusting plate, and the outer side of the limiting rod is slidably connected to the inner side of the limiting hole, so that when the adjusting plate moves, it can only slide along the outer side of the limiting rod.

[0011] A further improvement is that a circular hole is provided in the middle of the fixed plate, and the outer side of the lower end of the first threaded rod is rotatably connected to the inner side of the circular hole. There are two limiting rings, and the two limiting rings are slidably connected to the upper and lower sides of the middle position of the fixed plate on adjacent sides. Thus, when the first threaded rod rotates, the two limiting rings at its lower end will rotate on the upper and lower sides of the fixed plate, so that the first threaded rod can only rotate while maintaining its position.

[0012] A further improvement is that a first threaded hole is provided in the middle of the interior of the adjustment plate, and the outer side of the first threaded rod is threadedly connected to the inner side of the first threaded hole. Thus, when the first handle is rotated so that the first threaded rod rotates in the first threaded hole, the adjustment plate can slide along the outer side of the limiting rod.

[0013] A further improvement is that a second threaded hole is provided at the middle position of the right end inside the top plate, and a threaded groove is provided at the middle position of the upper end of the right support plate. The outer side of the second threaded rod is threaded to the inner side of the second threaded hole, and the outer side of the lower end of the second threaded rod is threaded to the inner side of the threaded groove. The upper left end of the left support plate is hinged to the left side of the top plate, so that the second threaded rod is threaded to the second threaded hole and then threaded to the threaded groove, thereby fixing the top plate to the upper end of the right support plate.

[0014] A further improvement is that the lower side of the pressure plate abuts against the upper side of the pressure holding plate, so that when the top plate is fixed to the upper side of the left support plate and the right support plate, the pressure plate at the lower end of the top plate will move to contact the upper side of the pressure holding plate, and at the same time the spring will be compressed to squeeze the pressure holding plate.

[0015] In summary, this application discloses a high-efficiency pressure-holding dispensing bonding device.

[0016] In this technical solution, when applying adhesive to the earphone shell placed in the pressure-holding base at the top of the base, the second handle can be rotated first to move the second threaded rod upward while rotating in the second threaded hole and threaded groove until the second threaded rod moves out of the threaded groove at the top of the right support plate. Then, the top plate can be rotated to move it away from the top of the base, so as not to hinder the adhesive application. At this time, the adhesive application on the earphone shell above the pressure-holding base can be performed conveniently and efficiently.

[0017] Furthermore, after fixing the top plate to the upper side of the right support plate, and simultaneously adjusting the pressure plate at the lower end of the plate to contact the upper side of the pressure holding plate, rotating the first handle causes the first threaded rod to rotate, which in turn drives the adjusting plate to slide along the outer side of the limiting rod. This changes the degree of compression of the spring between the adjusting plate and the pressure plate, thereby changing the pressure on the lower pressure holding plate. This allows the pressure on the pressure holding plate to be adjusted according to the pressure required when the upper end of the earphone shell of the pressure holding base is pressurized.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model provides a technical solution: a high-efficiency pressure-holding adhesive bonding device, including a base 1 and a left support plate 2. The left support plate 2 is fixedly connected to the upper left end of the base 1, and a right support plate 3 is fixedly connected to the upper right end of the base 1. A top plate 4 is connected to the upper side of the left support plate 2 and the right support plate 3, and a bonding mechanism is connected to the upper end of the base 1.

[0026] The bonding mechanism includes a pressure-holding base 501 connected to the upper end of the base 1. A pressure-holding plate 502 is connected to the upper side of the pressure-holding base 501. Positioning posts 514 are fixedly connected to the four corners of the lower side of the pressure-holding plate 502. A rectangular groove is formed at the middle position of the upper side of the base 1. The outer side of the lower end of the pressure-holding base 501 is slidably connected to the inner side of the rectangular groove. A placement groove is formed at the middle position of the upper end of the pressure-holding base 501, and the earphone shell to be bonded is placed in the placement groove. The four corners of the upper side of the pressure-holding base 501... A positioning groove is provided, the upper side of the pressure holding base 501 abuts against the lower side of the pressure holding plate 502, and the outer side of the positioning post 514 is slidably connected to the inner side of the positioning groove. Thus, when the pressure holding plate 502 is placed on the upper side of the pressure holding base 501 for pressure holding, the positioning post 514 on the lower side of the pressure holding plate 502 slides into the positioning groove inside the pressure holding base 501, so that the pressure holding plate 502 can be accurately installed on the upper end of the pressure holding base 501 to hold pressure on the earphone shell in the pressure holding base 501.

[0027] A fixed plate 503 is connected to the middle position inside the top plate 4. A first threaded rod 504 is connected to the middle position of the fixed plate 503. A limit ring 505 is fixedly connected to the outer side of the lower end of the first threaded rod 504. A first handle 506 is welded to the upper end of the first threaded rod 504. Limit rods 507 are fixedly connected to the left and right ends of the upper side of the fixed plate 503. A baffle 508 is welded to the upper side of the limit rod 507. An adjusting plate 509 is connected to the outer end of the first threaded rod 504. A through groove is opened in the middle position inside the top plate 4. The left and right sides of the fixed plate 503 are fixedly connected to the left and right ends of the inner side of the through groove. Limit holes are opened in the left and right ends of the adjusting plate 509. The outer side of the limit rod 507 is slidably connected to the inner side of the limit hole. Thus, when the adjusting plate 509 moves, it can only slide along the outer side of the limit rod 507, which plays a limiting role in the movement of the adjusting plate 509.

[0028] A circular hole is provided in the middle of the fixed plate 503. The outer side of the lower end of the first threaded rod 504 is rotatably connected to the inner side of the circular hole. There are two limiting rings 505, and the two limiting rings 505 are slidably connected to the upper and lower sides of the middle position of the fixed plate 503 on the adjacent side. So when the first threaded rod 504 rotates, the two limiting rings 505 at its lower end will rotate on the upper and lower sides of the fixed plate 503, so that the first threaded rod 504 can only rotate while keeping its position unchanged, thus limiting the first threaded rod 504.

[0029] The adjusting plate 509 has a first threaded hole in the middle. The outer side of the first threaded rod 504 is threaded to the inner side of the first threaded hole. When the first handle 506 is rotated so that the first threaded rod 504 rotates in the first threaded hole, the adjusting plate 509 can slide along the outer side of the limiting rod 507, changing the height position of the adjusting plate 509. At the same time, the position of the pressure plate 511 at the lower end changes as well.

[0030] Springs 510 are fixedly connected to the four corners of the lower side of the adjusting plate 509. A pressure plate 511 is fixedly connected to the lower end of the springs 510. A second threaded rod 512 is connected to the middle position of the right end inside the top plate 4. A second handle 513 is welded to the upper end of the second threaded rod 512. A second threaded hole is opened at the middle position of the right end inside the top plate 4. A threaded groove is opened at the middle position of the upper end of the right support plate 3. The outer side of the second threaded rod 512 is threaded to the inner side of the second threaded hole. The outer side of the lower end of the second threaded rod 512 is threaded to the inner side of the threaded groove. The upper left side of the left support plate 2 is hinged to the left side of the top plate 4. Thus, after the right end of the top plate 4 is rotated to the upper side of the right support plate 3, the second threaded rod 512 is threaded into the second threaded hole and then threaded into the threaded groove, so that the top plate 4 is fixed to the upper end of the right support plate 3.

[0031] The lower side of the pressure plate 511 abuts against the upper side of the pressure holding plate 502. Thus, when the top plate 4 is fixed to the upper side of the left support plate 2 and the right support plate 3, the pressure plate 511 at the lower end of the top plate 4 will move to contact the upper side of the pressure holding plate 502. At the same time, the spring 510 will compress and squeeze the pressure holding plate 502, pressing the pressure holding plate 502 tightly against the upper side of the pressure holding base 501, thereby continuously maintaining pressure on the earphone shell inside the upper end of the pressure holding base 501.

[0032] Working principle: During the dispensing and pressure holding process, first rotate the second handle 513 to rotate the second threaded rod 512 and move it upwards until the second threaded rod 512 moves out of the threaded groove at the upper end of the right support plate 3. Then rotate the top plate 4 so that it is no longer above the base 1. Next, remove the pressure holding plate 502 on the upper side of the pressure holding base 501 at the upper end of the base 1. Then place the earphone shell to be dispensed and pressure held in the placement groove at the upper end of the pressure holding base 501. Then, dispense glue onto the earphone shell. After the glue dispensing is completed, place the pressure holding plate 502 on the upper side of the pressure holding base 501. Rotate the top plate 4 to the upper side of the left support plate 2 and the right support plate 3, then reverse the second handle 513 so that the second threaded rod 512 moves down into the threaded groove, fixing the top plate 4 to the upper side of the left support plate 2 and the right support plate 3. At the same time, rotate the pressure plate 511 to the upper side of the pressure holding plate 502. Finally, rotate the first handle 506 so that the first threaded rod 504 rotates, causing the adjusting plate 509 to move, adjusting the spring 510 to the required compression amount, and pressing the pressure holding plate 502 with the required force. At the same time, the pressure holding plate 502 presses and adheres to the earphone shell above the pressure holding base 501.
