Description

Technical Field

[0001] The present invention relates to the technical field of cleaning the tin flow liquid level of a wave soldering machine, and particularly to a small wave peak cleaning device for a wave soldering machine. Background Art

[0002] As one of the commonly used devices in electronic manufacturing, a wave soldering machine is widely used in the soldering process of printed circuit boards (PCBs). The core of wave soldering is to control the flow of molten solder to form a wave-shaped tin liquid surface, and the electronic component pins are soldered to the PCB through the tin wave. However, during the operation of the wave soldering machine, due to the continuous circulation, heating, and cooling of the tin liquid in the tin furnace, irregular small wave peaks are likely to be generated on the wave surface. If these small wave peaks are not cleaned in time, it will affect the soldering quality, resulting in problems such as poor soldering, excessive solder joints, or missing solder joints.

[0003] The patent with the publication number CN101690988B discloses a small wave peak cleaning device for a wave soldering machine, including a fixed block fixedly arranged at the upper end of the small wave peak of the wave soldering machine. One side of the fixed block is provided with a movable block connected to the tin tank. The fixed block and the movable block together form a tin outlet for generating small wave peaks. It is characterized in that a power device is arranged outside the movable block, and the power device is connected to the movable block to drive the movable block to open. This device has a simple structure and is easy to implement, greatly improving the work efficiency of tin slag cleaning. Although this patent can also clean the tin slag.

[0004] Most current wave soldering machines rely on manual operation to clean the wave peaks in the tin furnace or clean them through simple mechanical means. Manual cleaning is not only time-consuming and laborious but also has certain risks. Especially during high-speed production, manual intervention may lead to a decrease in production efficiency. Although existing mechanical cleaning devices can clean the small wave peaks in the tin furnace to a certain extent, due to the limitations of the structure and cleaning method, they still cannot comprehensively solve the difficulties existing in the small wave peak cleaning process, especially in a production environment with high-precision requirements.

[0034] As Figures 3 - 5As shown in the figure, the lifting unit 6 includes a transmission assembly. The transmission assembly is connected to the main body 1, and a sliding assembly for driving the cleaning unit 7 to move is installed on the transmission assembly.

[0038] The cleaning plate assembly further includes a high-temperature resistant motor five 718, a first rack 720 and a second rack 722. The first rack 720 is fixedly installed at the bottom end of the first cleaning plate 712. The second rack 722 is fixedly installed at the bottom end of the third cleaning plate 714.

The inner radius of the incomplete gear one 705 is larger than the outer radius of the incomplete gear two 709. Two symmetrically distributed first sliding grooves 710 are arranged on the incomplete gear one 705.

[0041] The cleaning unit 7 further includes four connecting brackets 708.

Start the high-temperature resistant motor four 707. The output end of the high-temperature resistant motor four 707 drives the incomplete gear two 709 to rotate through the gear two 706. The incomplete gear two 709 drives the multi-angle adjustment housing 702 to have an angular offset, so that the angle at which the cleaning plate assembly on the multi-angle adjustment housing 702 fits the small wave crest to be cleaned is more appropriate. When the area of the small wave crest that needs to be cleaned is large, start the high-temperature resistant motor five 718.

The cylinder arm of the high-temperature resistant cylinder two 803 is connected to the suction housing 804.

[0045] After the cleaning plate assembly completes cleaning and resets, start the two high-temperature resistant cylinders two 803. The cylinder arms of the two high-temperature resistant cylinders two 803 drive the two suction housings 804 to approach until they fit. The two storage bodies 805 and the sliding housing 701 form an adsorption space. Then start the high-temperature resistant suction device 801. The high-temperature resistant suction device 801 sucks and stores the residual solder slag on the cleaning plate one 712, the cleaning plate two 713, and the cleaning plate three 714 through the hose, and then conducts centralized treatment.

[0046] Working principle: When it is necessary to clean the small wave crest, start the high-temperature resistant cylinder 1 2. The cylinder arm of the high-temperature resistant cylinder 1 2 drives the movable stop block 3 to slide on the small wave crest 101 of the wave soldering machine. At this time, the space at the tin outlet 5 becomes larger. Start the high-temperature resistant motor 1 601. The output end of the high-temperature resistant motor 1 601 drives the transmission shaft 2 610 to rotate, and two groups of high-temperature resistant belts 1 602 rotate. The high-temperature resistant belt 1 602 drives the transmission shaft 1 604 to rotate. The transmission shaft 1 604 drives the lead screw 1 605 to rotate through the high-temperature resistant belt 2 603. The lead screw 1 605 drives the lifting outer shell 608 to move up and down through the thread. Start the high-temperature resistant motor 2 609. The output end of the high-temperature resistant motor 2 609 drives the lead screw 2 611 to rotate. The lead screw 2 611 drives the sliding outer shell 701 to move left and right through the thread. Start the high-temperature resistant motor 3 703. The output end of the high-temperature resistant motor 3 703 drives the gear 1 704 to rotate. The gear 1 704 drives the incomplete gear 1 705 to rotate. The incomplete gear 1 705 drives the multi-angle adjustment outer shell 702 to have an angular offset. Start the high-temperature resistant motor 4 707. The output end of the high-temperature resistant motor 4 707 drives the incomplete gear 2 709 to rotate through the gear 2 706. The incomplete gear 2 709 drives the multi-angle adjustment outer shell 702 to have an angular offset, so that the angle at which the cleaning component on the multi-angle adjustment outer shell 702 fits the small wave crest to be cleaned is more appropriate. When the area of the small wave crest that needs to be cleaned is large, start the high-temperature resistant motor 5 718. The output end of the high-temperature resistant motor 5 718 drives the gear 3 721 to rotate. The gear 3 721 drives the rack 1 720 and the rack 2 722 to move away from each other. The rack 1 720 drives the cleaning plate 1 712 to move. The rack 2 722 drives the cleaning plate 3 714 to move. At this time, the cleaning plate 1 712, the cleaning plate 2 713, and the cleaning plate 3 714 form a larger cleaning area. After the cleaning component completes cleaning and resets, start two high-temperature resistant cylinders 2 803. The cylinder arms of the two high-temperature resistant cylinders 2 803 drive the two suction outer shells 804 to approach and fit together. The two chambers 805 and the sliding outer shell 701 form an adsorption space. Then start the high-temperature resistant suction device 801. The high-temperature resistant suction device 801 sucks and stores the residual solder dross on the cleaning plate 1 712, the cleaning plate 2 713, and the cleaning plate 3 714 through a hose, and then centrally processes it.
