Description

Technical Field

[0001] This utility model relates to the field of electronic paste coating technology, specifically to an electronic paste applicator. Background Technology

[0002] In today's electronics manufacturing industry, electronic paste is one of the most common materials. It is considered a key material for component packaging, electrodes, and interconnects, primarily used in the manufacture of integrated circuits, resistors, capacitors, and other electronic components. In application, an electronic paste coater is typically used to uniformly coat the substrate surface with electronic paste, forming a uniform coating. This equipment has significant application value in electronics manufacturing.

[0003] For example, Chinese Patent Publication No. CN220861877U discloses an electronic paste coating device, belonging to the field of coating device technology, including: a base plate and a processing box; a processing groove, opened in the processing box, the processing groove having an arc-shaped side, an adjusting plate provided in the processing groove, a handle provided at one end of the adjusting plate, an adjusting shaft rotatably connected to the upper end of the adjusting plate, a bearing plate adapted to the processing groove provided at the upper end of the adjusting shaft; a threaded rod, rotatably connected in the processing groove, a matching positioning plate sleeved on the outside of the threaded rod, a material collection groove opened in the positioning plate, and a nozzle provided at the bottom end of the material collection groove; this utility model, through the adjusting shaft and adjusting wheel set at the bottom end of the bearing plate, and the drive wheel at the output end of the first servo motor, in conjunction with the threaded rod and the positioning plate, enables the nozzle to comprehensively coat the electronic paste on the substrate surface, making the electronic paste coating device more applicable;

[0004] By referring to the above comparative documents, it can be seen that the existing technology still has the following shortcomings. When coating the substrate surface with electronic paste, the substrate needs to be clamped and positioned. However, when clamping and positioning the substrate, it is necessary to clamp and limit it on all four sides. Otherwise, the coating position of the substrate is prone to deviation, which will affect the coating quality. In addition, if the time for disassembling and assembling a new substrate is long after the existing coating device has finished coating the previous substrate, it is difficult to quickly replace the next substrate to continue coating. The coating efficiency of the substrate operation is not good. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an electronic paste applicator to solve problems such as inconvenient substrate clamping and positioning, and poor coating efficiency.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an electronic paste applicator, comprising a coating frame and a paste tank, wherein the paste tank is fixed to the top of the coating frame;

[0007] A U-shaped frame is fixed in the middle of the coating rack. A ring frame is provided inside the U-shaped frame. Several mounting platforms are fixed around the ring frame. A positioning groove is opened on the outer side of the mounting platform. Spring return rods are fixed around the inner wall of the positioning groove. A support plate is connected to the bottom of the positioning groove. Positioning clamps are provided around the support plate. Each positioning clamp is connected to the end of the spring return rod. Push-pull components are provided on the inner side of the coating rack.

[0008] The rotating frame is rotatably connected to a rotating shaft, and the ring frame is fixedly sleeved around the rotating shaft. A brake motor and a PLC controller are fixed at the front end of the rotating frame, and the front end of the rotating shaft is connected to the power end of the brake motor.

[0009] Preferably, the lower end of the slurry tank is connected to a metering valve, and the lower end of the metering valve is connected to a coating nozzle.

[0010] Preferably, each push-pull assembly includes a synchronization plate, an inclined block, a pressure block, a return spring, a pull rod, and a pull ring. The bottom of the mounting platform has openings around its perimeter that communicate with the positioning groove. Each synchronization plate has four pieces, which are connected one by one to the outside of the four positioning clamps, and each synchronization plate passes through the adjacent openings.

[0011] Preferably, each of the inclined blocks has four blocks, which are connected one by one to the inner side of the four synchronous plates. The pressure block is located between the inclined block and the mounting platform, and the return springs are all connected between the pressure block and the mounting platform.

[0012] Preferably, the pressure block is inclined on all four sides, and the inclined surface of the pressure block matches the inclined block.

[0013] Preferably, all the pull rods are fixed to the inside of the pressure block, and all the pull rods slide through the ring frame, and all the pull rings are connected to the ends of the pull rods.

[0014] This utility model provides an electronic paste applicator, which has the following beneficial effects:

[0015] The spring-loaded return rod allows the positioning clamps to easily hold and position the substrate within the positioning groove. The four positioning clamps also securely hold the substrate around its perimeter, facilitating precise positioning and electronic paste coating. This prevents misalignment during coating, ensuring coating quality. After coating, pulling the pull rings releases the four positioning clamps around the substrate, allowing for easy removal and replacement. The brake motor rotates the ring frame and mounting platform, enabling quick and easy replacement of the next substrate on the mounting platform, saving time and improving coating efficiency.

[0025] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-8This utility model provides a technical solution: an electronic paste applicator, including a coating frame 1 and a paste tank 2. The paste tank 2 is fixed to the top of the coating frame 1. A U-shaped frame 5 is fixed in the middle of the coating frame 1. An annular frame 7 is provided inside the U-shaped frame 5. Several mounting platforms 8 are fixed around the annular frame 7. A positioning groove 9 is opened on the outer side of the mounting platform 8. Spring return rods 10 are fixed around the inner wall of the positioning groove 9. A support plate 12 is connected to the bottom of the positioning groove 9. Positioning clamps 11 are provided around the support plate 12. The positioning clamps 11 are connected to the ends of the spring return rods 10 one by one. Push-pull components are provided inside the coating frame 1. Each push-pull component includes a synchronization plate 14, an inclined block 15, a pressure block 16, a return spring 17, a pull rod 18, and a pull ring 19. A metering valve 3 is connected to the lower end of the paste tank 2. A coating nozzle 4 is connected to the lower end of the metering valve 3.

[0027] When coating a substrate using this coating machine, the substrate is first placed into the positioning groove 9. During this process, the pull ring 19 pulls the pull rod 18 and the pressure block 16, causing the pressure block 16 to stretch the return spring 17. Then, the pressure block 16 pushes the inclined block 15, the synchronization plate 14, and the positioning clamp 11 outwards via the inclined surface. The positioning clamp 11 compresses the spring return rod 10. The substrate is then placed back into the positioning groove 9 and supported by the support plate 12. After releasing the pull ring 19, the return force of the return spring 17 causes the pressure block 16, pull rod 18, and pull ring 19 to reset. The spring return rod 10 will cause the positioning clamp 11, the synchronization plate 14 and the inclined block 15 to reset. At this time, the four positioning clamps 11 in the same positioning groove 9 will be conveniently clamped around the substrate. With the paste tank 2 filled with electronic paste, the metering valve 3 is activated and the electronic paste in the paste tank 2 is discharged into the coating nozzle 4. Then the coating nozzle 4 coats the electronic paste onto the substrate surface. In summary, this facilitates the accurate clamping and positioning of the substrate and the coating of electronic paste, and avoids the substrate coating position from deviating, which helps to ensure the coating quality of the substrate.

[0028] The rotating frame 5 is rotatably connected to a rotating shaft 6. The ring frame 7 is fixedly sleeved around the rotating shaft 6. A brake motor 20 and a PLC controller 21 are fixedly installed at the front end of the rotating frame 5. The front end of the rotating shaft 6 is connected to the power end of the brake motor 20.

[0029] When it is necessary to coat the surface of the next substrate with electronic paste, and assuming that each positioning slot 9 has a substrate installed, the PLC controller 21 is set to be connected to the brake motor 20. The PLC controller 21 controls the brake motor 20 to work. When the brake motor 20 works, it drives the rotating shaft 6, the ring frame 7, the mounting table 8 and the substrate to rotate together until the next substrate is located directly below the coating nozzle 4. Then the PLC controller 21 controls the brake motor 20 to stop working, and the rotating shaft 6, the ring frame 7, the mounting table 8 and the substrate stop rotating. This process is repeated, which facilitates the convenient and quick replacement of the next substrate in the mounting table 8 for coating processing, thereby improving the efficiency of coating processing.

[0030] The mounting platform 8 has openings 13 around its bottom that communicate with the positioning grooves 9. The synchronization plates 14 are provided in four pieces and are connected to the outside of the four positioning clamps 11. The synchronization plates 14 are inserted through the adjacent openings 13. The inclined blocks 15 are provided in four pieces and are connected to the inside of the four synchronization plates 14. The pressure block 16 is located between the inclined block 15 and the mounting platform 8. The return springs 17 are connected between the pressure block 16 and the mounting platform 8. The pressure block 16 is inclined on all four sides and its inclined surface matches the inclined block 15. The pull rods 18 are fixed to the inside of the pressure block 16 and slide through the ring frame 7. The pull rings 19 are connected to the ends of the pull rods 18.

[0031] When the coated substrate needs to be removed from the positioning groove 9, and the coated substrate is far away from the coating nozzle 4, the corresponding pull rod 18 and pressure block 16 are pulled by the pull ring 19. The pressure block 16 will stretch the return spring 17. Then, the pressure block 16 pushes the inclined block 15, the synchronization plate 14 and the positioning clamp 11 outward through the inclined surface. The positioning clamp 11 will compress the spring return rod 10. Therefore, the spring return rod 10 will drive the positioning clamp 11 away from the substrate, so that the positioning clamp 11 no longer clamps the substrate. At this time, the substrate can be easily removed from the positioning groove 9 for replacement, and it is convenient to install the substrate to be coated into the positioning groove 9. Moreover, the process of replacing the coated substrate will not affect the normal coating of the substrate directly below the coating nozzle 4. Thus, the coating and disassembly of the substrate can be carried out simultaneously. In summary, the time for substrate replacement and coating processing is effectively saved, and the operation is fast and convenient.

[0032] Working principle:

[0033] Pulling the pull rod 18 and the pressure block 16 by the pull ring 19 will stretch the return spring 17. Then, the pressure block 16 will push the inclined block 15, the synchronization plate 14 and the positioning clamp 11 outward through the inclined surface. The positioning clamp 11 will compress the spring return rod 10. Then, the substrate is placed into the positioning groove 9 and supported by the support plate 12. After releasing the pull ring 19, the return force of the return spring 17 will drive the pressure block 16, the pull rod 18 and the pull ring 19 to reset. At the same time, the return force of the spring return rod 10 will drive the positioning clamp 11, the synchronization plate 14 and the inclined block 15 to reset. At this time, the four positioning clamps 11 in the same positioning groove 9 will be conveniently clamped around the substrate. With the paste tank 2 containing electronic paste, the metering valve 3 is activated and the electronic paste in the paste tank 2 is discharged into the coating nozzle 4. Finally, the coating nozzle 4 coats the electronic paste onto the surface of the substrate.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
