DETAILED DESCRIPTION

[0026] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The filter screen for the molten liquid surface of the wave soldering furnace involved in the present invention is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0027] Reference Figure 1-6 The utility model provides a filter screen for the molten liquid surface of a wave soldering furnace, comprising: a filter plate 1, a guide groove 2, a cleaning component, a guide component and a power component. The filter plate 1 is installed at the liquid outlet of the guide groove 2, the cleaning component is installed in the guide groove 2, and the surface of the filter plate 1 is cleaned by the cleaning component. The guide component is installed in the guide groove 2 and is close to the liquid inlet of the guide groove 2. The power component is installed on the surface of the guide groove 2, and the cleaning component and the guide component are driven to operate by the power component.

[0028] The cleaning assembly includes a cleaning bar 3, which is slidably installed in the guide groove 2 and contacts the surface of the filter plate 1. In this way, the cleaning bar 3 can scrape off the impurities intercepted by the filter plate 1 during its movement.

[0029] The cleaning assembly also includes a first sprocket 4 and a first chain 5. There are two first sprockets 4, and both are rotatably installed in the guide groove 2. The two first sprockets 4 are transmitted through the first chain 5. At the same time, the cleaning bar 3 is fixedly installed on the first chain 5. In this way, only the first sprocket 4 needs to rotate to drive the first chain 5 to rotate, and finally drive the cleaning bar 3 to move synchronously.

[0030] There are two groups of first sprockets 4 and first chains 5, which are symmetrically distributed in the guide groove 2 in the front and rear directions. At the same time, the first sprockets 4 in the corresponding front and rear directions are coaxially connected, so that the cleaning strip 3 can be ensured to move more stably.

[0031] A collecting bin 6 is provided on the side of the guide groove 2 . The collecting bin 6 is arranged on a side close to the filter plate 1 , and a collecting bucket 7 is slidably drawn inside the collecting bin 6 . Thus, impurities scraped off by the cleaning strip 3 will be sent to the collecting bucket 7 .

[0032] The guide assembly includes an impeller 8, which is rotatably installed in the guide groove 2, and the impeller 8 is placed at the liquid inlet of the guide groove 2. In this way, the high-temperature liquid tin can be pushed out of the filter plate 1 to form a wave crest by simply rotating the impeller 8. The power assembly includes a motor 9, and the end of the rotating shaft of the motor 9 is coaxially connected to the end of the rotating shaft of the impeller 8, thereby driving the impeller 8 to rotate.

[0033] The power assembly also includes a first bevel gear 10 and a second bevel gear 11. The first bevel gear 10 is rotatably mounted on the surface of the guide groove 2. The first bevel gear 10 is equipped with a first protective cover 12, and the first protective cover 12 covers the motor 9 shaft, the first bevel gear 10 and the second bevel gear 11. The second bevel gear 11 is rotatably mounted on the inner side of the first protective cover 12, and the first bevel gear 10 and the second bevel gear 11 are meshed. At the same time, the first bevel gear 10 and the motor 9 shaft are transmitted through the second sprocket 13 and the second chain 14. A transmission assembly is connected between the second bevel gear 11 and the first sprocket 4. In this way, the rotation of the motor 9 can drive the first bevel gear 10 to rotate through the second sprocket 13 and the second chain 14, and then drive the second bevel gear 11 to rotate. The second bevel gear 11 will drive the first sprocket 4 to rotate through the transmission assembly, and then drive the first chain 5 to rotate.

[0034] The transmission assembly includes a third sprocket 15 and a third chain 16. There are two third sprockets 15, one of which is coaxially connected to the second bevel gear 11, and the other is coaxially connected to a first sprocket 4. The two third sprockets 15 are transmitted through the third chain 16. In this way, the rotation of the second bevel gear 11 will drive the first sprocket 4 to rotate through the third sprocket 15 and the third chain 16.

[0035] The third sprocket 15 is provided with a second protective cover 17 , and the second protective cover 17 covers the third sprocket 15 and the third chain 16 , thereby protecting the third sprocket 15 and the third chain 16 .

[0036] Therefore, the complete usage process is to first install the entire device in the tin liquid tank of the wave soldering furnace, and then start the motor 9. The motor 9 will drive the impeller 8 to rotate, thereby pushing the high-temperature liquid tin to flow out of the filter plate 1 to form a wave crest. In this process, the first bevel gear 10 will be driven to rotate synchronously through the second sprocket 13 and the second chain 14, and then the second bevel gear 11 will be driven to rotate. The second bevel gear 11 will drive the first sprocket 4 to rotate through the third sprocket 15 and the third chain 16, and then the first chain 5 will be driven to rotate, and finally the cleaning strip 3 will be driven to move synchronously. When the cleaning strip 3 moves, it will synchronously scrape off the impurities intercepted by the filter plate 1 and send it to the collecting bucket 7. This reciprocating process can ensure that the filter plate 1 is always clean, thereby ensuring that the wave crest of the liquid tin is stable and uniform.

[0037] In summary, during the entire use process, the cleaning component can be used to scrape off the impurities intercepted by the filter plate 1 in real time, thereby effectively ensuring the cleanliness of the surface of the filter plate 1. The entire process no longer requires the user to frequently stop the machine for cleaning, effectively ensuring the production rhythm and making it more convenient to use.

[0038] At the same time, since the cleaning strip 3 will continue to move in the tin liquid, it will stir the tin liquid, thereby prompting the tin slag contained in the tin liquid to separate quickly, thereby improving the slag removal effect, and the impurities scraped off by the cleaning strip 3 will also accumulate in the collecting bucket 7, thereby preventing them from escaping again and affecting the quality of the tin liquid, further ensuring the welding effect.

[0039] It should be noted that in the present application, all components are made of stainless steel, which can effectively prevent the adhesion of high-temperature liquid tin, and even the tin liquid can be easily removed after adhesion.

[0040] Finally, it should be noted that: the drawings of the embodiments disclosed in the present utility model only involve structures related to the embodiments disclosed in the present utility model, and other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of the present utility model can be combined with each other;

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
