Description

Technical Field

[0001] This utility model relates to the field of SMT reflow soldering technology, specifically to a foreign matter collection fixture suitable for reflow soldering equipment. Background Technology

[0002] Reflow soldering equipment is a core piece of equipment in electronic product manufacturing for surface mount technology (SMT) soldering. It precisely controls the temperature profile to melt solder paste pre-coated onto the pads of a printed circuit board (PCB) at high temperatures, wetting the component leads and forming a strong electrical connection after cooling. The equipment mainly consists of four parts: a heating system, a conveyor system, a cooling system, and a control system. Its conveyor system relies on a chain-driven conveyor belt to carry the PCB board through the furnace at a uniform speed.

[0003] However, existing reflow soldering equipment presents significant cleaning and maintenance challenges. Due to the open lubrication design of the transmission system, when operators add lubricating oil via oil cans or drip devices, the centrifugal force generated by the chain movement and the deviation in the drip angle prevent the lubricating oil from fully adhering to the chain bearings. Simultaneously, residual material from the chain itself falls, causing some lubricating oil and foreign matter to drop directly onto the bottom of the furnace and the front and rear transmission ports. The front and rear transmission ports are particularly contaminated, severely impacting the cleanliness of the reflow soldering equipment. Furthermore, the narrow space and complex layout of the heating components inside the furnace typically require companies to shut down the machine for several hours and use specialized cleaning equipment to thoroughly clean the oil and foreign matter inside the equipment, making cleaning extremely difficult.

[0029] Please see Figures 1 to 3 This utility model provides a foreign matter collection clamp suitable for reflow soldering equipment, which is installed on a crossbar below the front and rear chain of the reflow soldering equipment. The foreign matter collection clamp includes a long strip-shaped collection top shell 1 and a connecting side plate 2 disposed on the front side of the collection top shell 1. The top of the collection top shell 1 is provided with a long strip-shaped collection groove 11, and the connecting side plate 2 is provided with a plurality of magnets that are magnetically connected to the crossbar at intervals along its length. By installing the foreign object collection clamp on the crossbar below the front and rear chains of the reflow soldering equipment, the elongated collection groove 11 at its top covers the projected area of ​​the chain, automatically collecting oil and foreign objects falling from the chain. This prevents oil and foreign objects from falling directly into the bottom of the furnace and the front and rear transfer ports, thus reducing internal contamination. The automatic collection of oil and foreign objects effectively improves the cleanliness of the reflow soldering equipment. Furthermore, the use of the foreign object collection clamp allows workers to simply remove the clamp periodically and empty the collected oil and foreign objects, significantly reducing cleaning difficulty and time costs. In addition, the foreign object collection clamp is magnetically connected to the crossbar via multiple magnets on the connecting side plate 2, making installation and removal very convenient. Workers can easily install the clamp onto the equipment and quickly remove it for cleaning when needed. The overall structure of the foreign object collection clamp is relatively simple, consisting of an elongated collection top shell 1 and connecting side plates 2, making the clamp easy to manufacture and maintain, while also reducing costs.

[0030] In one embodiment, the front side of the collecting top shell 1 is connected to the upper end of the connecting side plate 2 by screws. Connecting the collecting top shell 1 and the connecting side plate 2 together with screws significantly improves the structural stability of the clamp, ensuring that the clamp will not loosen or fall off due to vibration or external force during equipment operation. The screw connection method makes the installation and disassembly of the collecting top shell 1 and the connecting side plate 2 relatively easy; workers can easily tighten or loosen the screws using tools such as screwdrivers, thus facilitating the assembly, maintenance, or replacement of the clamp.

[0031] Please see Figures 1 to 3 Specifically, the front side of the collecting top shell 1 is provided with a plurality of first screw holes 12 at intervals along its length direction, and the upper end of the connecting side plate 2 is provided with a plurality of second screw holes 21 at intervals along its length direction. The first screw holes 12 and the second screw holes 21 correspond one-to-one, which can ensure the positioning accuracy of the two when connected and ensure the overall accuracy and stability of the fixture.

[0032] Please see Figures 1 to 3 In one embodiment, the lower end of the connecting side plate 2 is provided with a plurality of magnet openings 22 spaced apart along its length for embedding magnets, which can ensure the magnets are securely fixed on the fixture. The magnet openings 22 are provided to accurately accommodate the magnets and prevent them from moving or falling off due to vibration or external force during equipment operation.

[0033] In one specific embodiment, there are 11 magnets and 11 magnet openings 22, and the magnets are 5*10mm in size to provide sufficient magnetic force to fix the clamp inside the equipment, so that the clamp is more stable during the operation of the equipment and is not easy to loosen or fall off due to vibration or external force.

[0034] Please see Figures 1 to 3 In one embodiment, both the collecting top shell 1 and the connecting side plate 2 are rectangular strip structures, and the collecting trough 11 has a rectangular cross-section. The rectangular strip structure makes the structure of the collecting top shell 1 and the connecting side plate 2 simple and clear, easy to manufacture and process, and has low manufacturing costs. It also makes full use of the space under the front and rear chains of the reflow soldering equipment, ensuring that the collecting top shell 1 fits tightly against the equipment, thereby maximizing the collection of fallen oil and foreign objects. The rectangular cross-section of the collecting trough 11 gives it a large capacity and opening area, enabling more effective collection and containment of oil and foreign objects. It also facilitates cleaning and maintenance, allowing workers to easily clean the dirt inside the collecting trough 11.

[0035] In one embodiment, the collecting top shell 1 is made of stainless steel sheet. Stainless steel sheet has excellent corrosion resistance and can be used for a long time in the high temperature, high humidity, and possible chemical environment of reflow soldering equipment without easily rusting or corroding, thereby extending the service life of the collecting top shell 1. At the same time, the surface of stainless steel sheet is smooth, does not easily adhere to oil and foreign matter, and is relatively easy to clean.

[0036] In one embodiment, the top housing 1 is made of aluminum alloy. Aluminum alloy is lighter than stainless steel, which helps reduce the overall weight of the fixture and also facilitates installation and disassembly operations by workers.

[0037] In one embodiment, the collecting top shell 1 is 500mm long, 50mm wide, and 13-25mm thick; the connecting side plate 2 is 500mm long, 75mm wide, and 5mm thick. The dimensions of the collecting top shell 1 and connecting side plate 2 allow them to cover a large area, effectively collecting oil and foreign matter falling from the chain, improving collection efficiency. They are also compatible with the crossbars under the front and rear chains of most reflow soldering equipment, offering strong versatility.

[0038] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.

[0039] The present utility model patent has been described above with reference to the accompanying drawings. Obviously, the implementation of the present utility model patent is not limited to the above-described manner. Any improvements made by adopting the inventive concept and technical solution of the present utility model patent, or the direct application of the inventive concept and technical solution of the present utility model patent to other occasions without modification, are all within the protection scope of the present utility model.
