Description

Technical Field

[0001] This utility model belongs to the technical field of dispensing bagged flux after high-temperature synthesis, and specifically relates to a bagged flux dispensing device. Background Technology

[0002] Solder paste is the main raw material of solder paste. Its main function is to remove contaminants from the surface of the solder pads, reduce the surface tension of the solder, and enable the solder to bond tightly to the pads. Solder paste is synthesized at high temperatures from rosin, organic amines, organic acids, organic amides, and organic solvents. At 120-130℃, the flux forms a high-viscosity paste. Therefore, it must be quickly filtered into a high-temperature resistant plastic bag and sealed at 130-140℃. After being spread evenly, it should be cooled to below 5℃ to form solder paste. It should then be brought back to room temperature before use.

[0003] Currently, the production process uses bagged flux, which requires manual cutting and squeezing. This process is inefficient, labor-intensive, and results in flux residue adhering to the inner wall of the bag, leading to waste (100-200g of flux is lost for every 5kg bag), increasing costs. Furthermore, the flux can get on the skin or clothing during manual squeezing, posing certain occupational health and safety hazards. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a bagged flux dispensing device that is simple in structure, highly efficient in squeezing and dispensing, safe and reliable, and cost-effective.

[0005] The technical solution adopted by this utility model is as follows:

[0006] A bagged flux dispensing device includes a support platform, two parallel guide rails mounted on the support platform, rollers with both ends respectively mounted on the guide rails, a rotary positioner mounted on the guide rails for positioning the rollers, and a motor connected to the roller shaft.

[0007] Furthermore, the bagged flux extrusion device also includes a feeding trough located outside the guide rail and roller and mounted on a support platform. The feeding trough is a flat rectangle with a hollow top and bottom, and is made of stainless steel plate, PP or PVC plate.

[0008] Furthermore, the lower end of the feeding trough is provided with a connector to be fixed to the support platform.

[0009] Furthermore, the roller is made of polypropylene (PP) material that is resistant to acid and alkali corrosion.

[0010] Furthermore, the support platform consists of a support surface and a lifting rod, with rollers installed at the bottom end of the lifting rod.

[0011] This utility model has the following advantages:

[0012] This invention features a simple structure. The rollers are quickly installed and positioned using guide rails and a rotary positioner on the support platform. A motor drives the rollers to operate at a set speed, resulting in high extrusion efficiency. This reduces the risk of flux contamination of human skin, ensuring safety and reliability. It also minimizes waste caused by residue in the bag after extrusion, reducing costs. The threaded lifting rod adjusts the height of the support platform, making operation convenient. The feeding chute is detachably connected to the support platform. During operation, it serves as the feeding chute; when not in use, it can be disassembled and placed on the rollers to prevent dust and other foreign matter from contaminating the rollers, thus ensuring the quality of the flux.

[0017] To achieve this, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 and 2 A bagged solder paste dispensing device includes a support platform 7, two parallel guide rails 5 mounted on the support platform, rollers 2 with their ends respectively mounted on the guide rails (the roller spacing and rotation speed are adjusted according to the thickness of the bagged solder paste and the amount dispensed), a positioner 6 mounted on the guide rails for positioning the rollers, and a motor 4 connected to the roller shaft. The guide rails and positioner on the support platform enable quick installation and positioning of the rollers, and the motor drives the rollers to run at a set speed. A horizontal slit is cut along the bottom edge of the bagged solder paste, and it is gently placed into the feeding trough from the top. When the bag reaches the roller, the positioner is released, allowing it to move downwards along the roller. When the bag reaches the end, the positioner is tightened, causing the roller to clamp the solder paste bag tightly. The roller rotates in the opposite direction at a set speed (e.g., 10 rpm), and the solder paste bag gradually moves upwards, squeezing the solder paste into a container for later use.

[0019] Reference Figure 3 and4 To facilitate operation and ensure safety, as well as the quality of the solder paste, the bagged solder paste extrusion device also includes a feeding trough 1, which is located on the outside of the guide rail and rollers and detachably mounted on the support platform. The feeding trough can also be detachably installed on the support platform via a connector 11. The feeding trough is made of lightweight materials such as thin stainless steel plate, PP or PVC plate, and is a flat rectangle with hollow top and bottom surfaces. The bagged solder paste is fed into the trough and aligned between the two rollers. When the device is running, it serves as the feeding trough; when idle, it can be disassembled and placed on the rollers to prevent dust and other foreign objects from contaminating the rollers and to keep the equipment clean. To facilitate operation and movement of the work point under different height conditions, the support platform consists of a support platform and a lifting rod 8. Rollers are installed at the bottom of the lifting rod, and a threaded lifting rod can also be used to adjust the height of the support platform. The support platform can be raised and lowered according to the height of the solder paste container. The container is placed under the rollers of the support platform, and the lifting rod is adjusted to a suitable height.

[0020] The rollers can be made of acid- and alkali-resistant polypropylene (PP). Since solder paste is a corrosive paste, the PP rollers effectively prevent the solder paste from corroding the rollers. The material has good heat resistance, surface smoothness, chemical stability, and strong resistance to acid and alkali corrosion, reducing the contamination of the solder paste by corrosive foreign matter. The PP rollers are not easy to tear the plastic bag, while having sufficient strength to complete the extrusion (scraping) of the solder paste. The feeding trough is made of stainless steel plate, PP or PVC plate, and is easy to disassemble.

[0021] This device primarily uses mechanical roller pressing, supplemented by manual adjustment, making it flexible to operate, reducing labor intensity, improving production efficiency, and ensuring operator safety. At the same time, the amount of flux paste adhering to the inner wall of the plastic bag is reduced from 100-200g to 5-10g, saving costs.

[0022] The operation method of this utility model is as follows:

[0023] 1. Prepare a container for the solder paste (such as a solder paste mixing tank), adjust the height of the support platform to be 1-2cm higher than the container opening, fix the lifting rod and rollers, and place the container directly under the roller;

[0024] 2. Take a certain amount of flux paste, such as 5kg / bag, cut a horizontal slit along the bottom edge of the flux paste bag, and gently place it into the feeding trough from the top. When the bag touches the roller, release the rotary positioner to allow the bag to move down the roller. When the bag reaches the end, tighten the positioner to make the roller clamp the bag tightly.

[0025] 3. Set the roller speed to 10 rpm, and set the two rollers to rotate outwards in opposite directions;

[0026] 4. Turn on the motor switch. As the rollers rotate in reverse, the flux bag gradually moves upward, and the flux is squeezed into the container.

[0027] 5. After extrusion is complete, turn off the power, loosen the roller, remove the flux bag, remove the feed chute, clean the roller, and then place the feed chute cover on the roller.

[0028] 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.
