Description

Technical Field

[0001] This utility model relates to the field of optical components, systems or instruments, and more specifically, to an SMT reflow soldering machine. Background Technology

[0002] In SMT manufacturing, reflow soldering machines are the core equipment for reliably soldering electronic components to printed circuit boards (PCBs). As electronic products become smaller, more integrated, and more diverse, different types of electronic components have significantly different requirements for reflow soldering process parameters, which necessitates that reflow soldering machines possess excellent adjustability.

[0003] Regarding the adjustment of transport tracks, the existing reflow soldering machine transport track width adjustment structure is rather cumbersome. When producing PCBs of different sizes, operators need to use various tools to manually adjust the positions of the baffles on both sides of the track, and it is difficult to ensure the parallelism and spacing accuracy of the baffles during the adjustment process. This adjustment method is not only time-consuming and labor-intensive, but also affects the stability of the track after frequent adjustments, easily causing the PCBs to shift or jam during transport, thus affecting the accuracy and consistency of soldering.

[0004] Therefore, this application proposes an SMT reflow soldering machine to solve the above problems. Utility Model Content

[0005] The present invention aims to solve the problems mentioned in the background art above, thereby providing an SMT reflow soldering machine;

[0006] To achieve the above objectives, this utility model provides the following technical solution: an SMT reflow soldering machine, comprising a main body, the main body being box-shaped, with two flip covers on the front of the main body allowing direct observation of the interior, conveyor rollers inside the main body, the conveyor rollers being arranged in a horizontal row, belts being installed in the gaps between the conveyor rollers, and a silicone layer being installed on the upper surface of the belts, the silicone layer being made of a high-temperature resistant material.

[0007] Preferably, the bottom of the conveyor roller is provided with an adjustment component, which includes: a belt, a drive rod, a telescopic mechanism, a frame, a top plate, and rollers, with rollers provided at both ends of the belt.

[0008] Preferably, the belt has a central frame, which is located in the space in the middle of the belt. There are four belts in total. The frame is rectangular in shape and extends beyond the left and right belts at both ends.

[0009] Preferably, the frame is provided with four top plates, which are located below the belt. The width of the top plates is the same as the width of the belt. Telescopic machines are provided at the bottom of both ends of the frame, which can raise the belt height through the top plates.

[0010] Preferably, the rollers are fixed in the transmission rods, which are configured as two rods, left and right, each with four rollers fixed on it.

[0011] Preferably, movable plates are provided on both sides of the conveyor roller, and the movable plates are made of two plates that are connected together, so that they can be extended and retracted to adjust the length. A rubber block is provided in the movable plate, and the rubber block is located above the conveyor roller and higher than the conveyor roller. Beneficial effects

[0012] The upper surface of the belt is covered with a silicone layer made of a high-temperature resistant material. This material has excellent high-temperature resistance and can be used for a long time at temperatures up to 200°C or even higher. In addition, the belt has excellent flexibility, aging resistance, and chemical corrosion resistance. It is not easily deformed and can maintain good mechanical properties.

[0013] The belt is raised by the top plate to better contact the components conveyed by the conveyor rollers. This also increases the contact area, thereby improving friction and allowing for better adjustment of the components. It prevents the components from deviating from their trajectory during the conveying process and coming into contact with the ends of the conveyor rollers, which could cause damage. The adjustment components are set in two groups, distributed left and right, to accommodate components of different sizes and prevent components from being too large or too small, which would prevent them from being unable to be adjusted properly.

[0014] The movable plate consists of two plates that fit together, allowing for extension and retraction to adjust its length. A rubber block is installed within the movable plate, positioned above and above the conveyor roller. This rubber block is also made of heat-resistant silicone. When small components are present, the rubber block can be manually pushed to restrict the component's path on the conveyor roller, preventing the component from being too small to be properly adjusted by the belt. The rubber block facilitates better component transport and prevents situations where normal transport is impossible. Attached Figure Description

[0022] 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.

[0023] Please see Figures 1 to 6 In this embodiment of the utility model, an SMT reflow soldering machine includes a main body 1, which is box-shaped. The front of the main body 1 has two flip covers 11, which allow direct observation of the interior of the main body 1. When problems occur, adjustments can be made in time. The main body 1 is equipped with conveyor rollers 12, which are arranged in a horizontal row and mounted on a frame at the bottom to form a stable structure. A belt 13 is provided in the gap between the conveyor rollers 12. The upper surface of the belt 13 is provided with a silicone layer. The silicone layer is made of a high-temperature resistant material, which has good high-temperature resistance and can be used for a long time at temperatures up to 200°C or even higher. In addition, the belt 13 has excellent flexibility, aging resistance and chemical corrosion resistance, is not easily deformed, and can maintain good mechanical properties.

[0024] Furthermore, an adjustment assembly is provided at the bottom of the conveyor roller 12. The adjustment assembly includes: belt 13, transmission rod 14, telescopic mechanism 15, frame 16, top plate 17, and rollers 21. Rollers 21 are provided at both ends of the belt 13. The frame 16 is located in the middle of the belt 13. The frame 16 is located in the space in the middle of the belt 13. There are four belts in total. The frame 16 is rectangular in shape and extends beyond the two belts 13 on the left and right sides.

[0025] The frame 16 is equipped with four top plates 17, which are located below the belt 13. The width of the top plates 17 is the same as the width of the belt 13. Telescopic mechanisms 15 are installed at both ends of the frame 16. The belt 13 can be raised through the top plates 17 to better contact the device conveyed by the conveyor roller 12. At the same time, the contact area can be increased, thereby improving the friction and better adjusting the device. This prevents the device from deviating from its trajectory during the conveying process and contacting the two ends of the conveyor roller 12, which would cause damage. The adjustment components are set in two groups, distributed on the left and right, which can be used for devices of different sizes to prevent the device from being too large or too small and thus unable to be adjusted properly.

[0026] Furthermore, the rollers 21 are fixed in the transmission rods 14. The transmission rods 14 are configured as two rods, left and right, and each of the transmission rods 14 is fixed with four rollers 21 to achieve unified operation and prevent the belts 13 from having different speeds and being unable to be effectively adjusted. There are gaps in the belts 13 to prevent the belts 13 from being too densely arranged and to continuously adjust the device through friction.

[0027] Furthermore, movable plates 18 are provided on both sides of the conveyor roller 12. The movable plates 18 are made of two plates that are connected together, so that they can be extended and retracted to adjust the length. A rubber block 19 is provided in the movable plate 18. The rubber block 19 is located above the conveyor roller 12 and is made of silicone heat-resistant material. When there are small parts, the rubber block 19 can be manually pushed to limit the path of the parts on the conveyor roller 12, preventing the parts from being too small to be properly adjusted by the belt 13. The rubber block 19 can better transport the parts and prevent the parts from being unable to be transported normally.

[0028] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
