[0037] The following will be combined with Figures 1 to 4 Describe the anti-oxidation structure and wave soldering device provided by the present utility model.

[0038] It should be noted that the anti-oxidation structure 10 provided by the present utility model is suitable for being installed on a wave soldering device to prevent the liquid tin from contacting with air to generate tin slag from entering the transmission bearing 50 at the output end of the driving device 40, causing damage to the transmission bearing 50.

[0039] Refer to Figures 1 to 3 As shown, the anti-oxidation structure 10 provided by the present utility model includes an anti-oxidation cover 110, a fixing member 120, and an air inlet member 130. Among them, an anti-oxidation cavity is formed inside the anti-oxidation cover 110 so that the transmission assembly of the wave soldering device is located inside the anti-oxidation cavity; the anti-oxidation cover 110 is connected to the fixing member 120; the air inlet member 130 is communicated with the anti-oxidation cavity, and the air inlet member 130 is suitable for introducing anti-oxidation gas into the anti-oxidation cavity.

[0040] It should be noted that the transmission assembly includes a bearing and a transmission shaft. During the process of continuously rotating and stirring the solder, due to the contact between the solder and air, it is easy to react with oxygen in the air and be oxidized to form elemental tin, and the tin slag is easy to climb upward along the transmission shaft and then enter the transmission bearing 50, resulting in the transmission bearing 50 being stuck and damaged.

[0041] The anti-oxidation structure 10 and wave soldering device provided by the present utility model are interconnected between the anti-oxidation cover 110 and the fixing member 120 to form an anti-oxidation cavity, and an anti-oxidation gas is introduced into the cavity through the air inlet member 130, which can ensure that the liquid tin is always in contact with the anti-oxidation gas, prevent the liquid tin from contacting with the air to generate tin dross, and further damage the bearing.

[0042] During specific implementation, the drive bearing 50 located therein can be protected by introducing an anti-oxidation gas into the anti-oxidation cavity. Among them, the anti-oxidation gas can be nitrogen, carbon dioxide, and inert gases (such as helium), etc. In this embodiment, nitrogen is taken as an example. Introducing the anti-oxidation gas inside the anti-oxidation cavity can isolate the contact between the liquid tin and the air, reduce the generation amount of tin dross inside the anti-oxidation cover 110, thereby reducing the tin dross adsorbed on the drive bearing 50 and preventing the drive bearing 50 from being damaged.

[0043] According to some embodiments of the present utility model, a cavity can be formed only inside the anti-oxidation cover 110 to form the above anti-oxidation cavity, and the drive bearing 50 is arranged inside the anti-oxidation cover 110 for protection. On this basis, in some other embodiments, a cavity can also be formed inside the fixing member 120, and this cavity is communicated with the cavity inside the anti-oxidation cover 110. The cavity formed inside the fixing member 120 and the cavity formed inside the anti-oxidation cover 110 are communicated to form an anti-oxidation cavity, which can increase the volume of the anti-oxidation cavity, improve the protection effect, and the anti-oxidation gas can be introduced into the anti-oxidation cavity through the cavity formed inside the fixing member 120, improving the flexibility of pipeline connection. The fixing member 120 plays a fixing role and is used to connect with the support frame 30 of the wave soldering device, thereby fixing the anti-oxidation structure 10. During use, since the fixing member 120 is located above the anti-oxidation cover 110 and the cavity inside it is far from the liquid level of the liquid tin, therefore, on the premise of meeting the spatial layout, the drive bearing 50 is usually arranged in the cavity formed inside the fixing member 120.

[0044] See Figures 1 to 3 As shown, according to some embodiments of the present utility model, a connection cavity adapted to connect with the anti-oxidation gas source is formed inside the fixing member 120, and the connection cavity is communicated with the anti-oxidation cavity. By forming an anti-oxidation cavity and a connection cavity inside the anti-oxidation cover 110 and the fixing member 120 respectively, the volume of the anti-oxidation cavity can be increased, and the protection effect on the drive bearing 50 can be improved.

[0045] According to some embodiments of the present utility model, the volume of the connection cavity is smaller than that of the anti-oxidation cavity. Since the connection cavity is located above the anti-oxidation cavity, when introducing anti-oxidation gas into the anti-oxidation cavity through the connection cavity, due to the relatively small volume of the connection cavity (upper cavity), when gas is introduced into it, a relatively high pressure will be generated during the expansion process of the gas. This pressure difference can drive the gas to flow into the anti-oxidation cavity (lower cavity), realizing the transmission and filling of the gas. And because the volume of the upper cavity is small, the gas can quickly reach a relatively high pressure after the gas is introduced, so that the gas transmission speed is accelerated and the response speed is faster.

[0046] See Figures 1 to 3 As shown, according to some embodiments of the present utility model, the air inlet member 130 is provided on the fixing member 120, and the air inlet member 130 is communicated with the connection cavity. Since the connection cavity is located above the anti-oxidation cavity and is relatively far from the liquid tin surface, by providing the air inlet member 130 on the fixing member 120, the air intake can be buffered through the connection cavity, preventing the air intake from affecting the liquid tin surface.

[0047] According to some embodiments of the present utility model, an air inlet is provided on the side wall of the fixing member 120, and the air inlet member 130 is provided at the air inlet. By providing the air inlet on the side wall of the fixing member 120, when introducing air, the anti-oxidation gas first acts on the inner wall of the connection cavity and does not directly act on the liquid tin surface, which can reduce the influence on the liquid tin surface during air intake.

[0048] According to some embodiments of the present utility model, the air inlet member 130 is welded to the air inlet. Through welding, the connection position between the air inlet member 130 and the air inlet hole can be sealed, and there is no need to additionally provide a sealing structure here.

[0049] In some embodiments, the air inlet and the air inlet member 130 can also be threadedly connected or snap-connected. When the air inlet and the air inlet member 130 are threadedly connected, the threaded connection position between the air inlet and the air inlet member 130 can be sealed by setting a threaded sealing tape. When the air inlet and the air inlet member 130 are snap-connected, a flexible sealing element can be pre-embedded in the air inlet, and the air inlet member 130 can be pressed into the flexible sealing element, and the deformation generated by the flexible sealing element is used for sealing.

[0050] According to some embodiments of the present utility model, the anti-oxidation structure 10 can also include a plurality of air inlet members 130, and the plurality of air inlet members 130 are all provided on the fixing member 120. By simultaneously introducing anti-oxidation gas into the connection cavity through the plurality of air inlet members 130, the air intake rate can be improved.

[0051] See Figures 1 to 3As shown, according to some embodiments of the present utility model, the fixing member 120 is threadedly connected to the anti-oxidation cover 110 to adjust the height of the lower end of the anti-oxidation cover 110 when the anti-oxidation cover 110 is rotated. By configuring the fixing member 120 and the anti-oxidation cover 110 to be threadedly connected, the height of the anti-oxidation cover 110 can be adjusted by rotating the anti-oxidation cover 110, and further, the position of the lower end of the anti-oxidation cover 110 relative to the liquid tin surface can be adjusted so that the lower end of the anti-oxidation cover 110 is always below the liquid tin surface, thereby preventing air from entering the anti-oxidation cavity. It is convenient to manually rotate the anti-oxidation cover 110 to adjust its height, and it is also convenient to rotate the anti-oxidation cover 110 with the help of an external driving structure to achieve automatic adjustment. It is convenient to install and disassemble the fixing member 120 and the anti-oxidation cover 110, and clean the tin slag inside the anti-oxidation cover 110 and the fixing member 120. When the transmission bearing 50 is protected by introducing an anti-oxidation gas into the anti-oxidation cavity, the threaded connection between the fixing member 120 and the anti-oxidation cover 110 can also ensure the airtightness of the anti-oxidation cavity and prevent the anti-oxidation gas from overflowing through the connection position between the fixing member 120 and the anti-oxidation cover 110. In addition, by configuring the fixing member 120 and the anti-oxidation cover 110 to be threadedly connected, after the anti-oxidation cover 110 is adjusted, the anti-oxidation cover 110 can be kept at the current height without other constraints by using thread self-locking, and there is no need to additionally set a limiting mechanism to limit the anti-oxidation cover 110.

[0052] According to some embodiments of the present utility model, when the anti-oxidation cover 110 is rotated manually, a hand-held part convenient for hand-held operation can be provided on the anti-oxidation cover 110. On this basis, the hand-held part can also be set as a mechanism for increasing the torque. For example, on the premise of meeting the space layout and anti-interference, an adjusting rod extending radially can be provided on the outer wall of the anti-oxidation cover 110. Since the part is fixed during use and the height of the anti-oxidation cover 110 needs to be adjusted, the anti-oxidation cover 110 can be rotated up and down by applying a force to the adjusting rod, and this structure can keep the operator's hand appropriately away from the liquid tin, improving the safety factor during operation.

[0053] According to some embodiments of the present utility model, to further improve the airtightness of the anti-oxidation cavity, a threaded sealing tape can be provided at the threaded connection position between the fixing member 120 and the anti-oxidation cover 110 to fill the incomplete surface defects at the threaded connection position between the fixing member 120 and the anti-oxidation cover 110 and prevent the leakage of the anti-oxidation gas.

[0054] According to some embodiments of the present utility model, sealant can also be filled at the threaded connection position between the fixing member 120 and the anti-oxidation cover 110 to enhance the airtightness of the anti-oxidation cavity.

[0055] See Figures 1 to 3As shown, according to some embodiments of the present utility model, for the anti-oxidation structure 10 provided by the present utility model, one end of the anti-oxidation cover 110 is provided with a first threaded section 111, and one end of the fixing member 120 is provided with a second threaded section 121. The first threaded section 111 is in threaded cooperation with the second threaded section 121. By respectively arranging the first threaded section 111 and the second threaded section 121 at the ends of the anti-oxidation cover 110 and the fixing member 120, it is convenient for the anti-oxidation cover 110 and the fixing member 120 to be threadedly connected, facilitating assembly, and can reduce the manufacturing difficulty of the anti-oxidation cover 110 and the fixing member 120.

[0056] See Figures 1 to 3 As shown, according to some embodiments of the present utility model, the anti-oxidation cover 110 includes a limiting portion 112 and a cylindrical main body portion. The limiting portion 112 is connected to one end of the main body portion, and a plurality of limiting walls are provided on the limiting portion 112. Since the connection between the anti-oxidation cover 110 and the fixing member 120 is a threaded connection, during use, the vibration of the device may cause the anti-oxidation cover 110 to rotate, deviating from the set position or even falling off. By providing the limiting portion 112 on the anti-oxidation cover 110, it can be limited to prevent it from rotating along its own axis, thereby improving the stability of the anti-oxidation cover 110 during use.

[0057] Specifically, see Figures 1 to 3 As shown, in this embodiment, the limiting portion 112 is a limiting boss provided at the upper end of the anti-oxidation cover 110, and the limiting boss has a plurality of limiting walls. During use, by the external fixing component abutting against the limiting walls and applying a limiting effect on the limiting boss, the anti-oxidation cover 110 can be prevented from rotating. In addition, this limiting boss structure also facilitates the disassembly and assembly of the anti-oxidation cover 110 using disassembly and assembly tools (such as a wrench).

[0058] According to some embodiments of the present utility model, the limiting portion 112 can also be provided in the middle or at the lower end of the anti-oxidation cover 110. And the limiting portion 112 is not limited to the above-mentioned limiting boss shape, as long as the limiting portion 112 can be in limiting cooperation with the external fixing component to achieve the purpose of preventing the anti-oxidation cover 110 from rotating along its own axis. For example, a limiting hole (which does not communicate with the cavity inside the anti-oxidation cover 110) can be provided on the anti-oxidation cover 110. During use, in cooperation with an external limiting pin, the anti-oxidation cover 110 can also be limited.

[0059] Next, see Figure 1 and Figure 2 , and describe in detail the anti-oxidation structure 10 according to the embodiments of the present utility model.

[0060] The anti-oxidation structure 10 includes an anti-oxidation cover 110, a fixing member 120, and an air inlet member 130. Among them, an anti-oxidation cavity is formed inside the anti-oxidation cover 110, a connection cavity is formed inside the fixing member 120, and the anti-oxidation cavity and the connection cavity are communicated. During use, the transmission bearing 50 on the output end of the driving device 40 is located inside the anti-oxidation cavity. The air inlet member 130 is connected to the gas source of the anti-oxidation gas, and the anti-oxidation gas is introduced into the anti-oxidation cavity. The anti-oxidation gas can isolate the contact between the liquid tin and the air, reduce the tin slag generated inside the anti-oxidation cover 110, and thus reduce the tin slag adsorbed on the transmission bearing 50.

[0061] A first threaded section 111 (internal threaded section) is provided at the upper end of the anti-oxidation cover 110, and a second threaded section 121 (external threaded section) is provided at the lower end of the fixing member 120. The anti-oxidation cover 110 and the fixing member 120 are threadedly connected through the first threaded section 111 and the second threaded section 121, which is convenient to adjust the height of the anti-oxidation cover 110 by rotating the anti-oxidation cover 110. The position of the lower end of the anti-oxidation cover 110 relative to the liquid surface of the tin material can be adjusted according to the liquid surface height of the liquid tin in the tin furnace 20, so that the lower end of the anti-oxidation cover 110 is always below the liquid surface of the tin material, which can effectively prevent air from entering the anti-oxidation cavity and does not require frequent addition of solder.

[0062] A limiting boss is provided at the upper end of the anti-oxidation cover 110, and the limiting boss has a plurality of limiting walls. During use, by abutting the external fixing member against the limiting wall and applying a limiting effect on the limiting boss, the anti-oxidation cover 110 can be prevented from rotating. In addition, this limiting boss structure also facilitates the disassembly and assembly of the anti-oxidation cover 110 using a disassembly and assembly tool (such as a wrench).

[0063] See Figure 3 As shown, the wave soldering device provided by the present invention includes a tin furnace 20, a support frame 30, a driving device 40, and the anti-oxidation structure 10 described in any one of the above embodiments. Among them, the support frame 30 is connected to the tin furnace 20, the driving device 40 is arranged on the support frame 30, a transmission bearing 50 is provided at the output end of the driving device 40, the fixing member 120 is connected to the support frame 30, and the transmission bearing 50 is located inside the anti-oxidation cavity.

[0064] For the wave soldering device provided by the present invention, since the above anti-oxidation structure 10 is used to protect the transmission bearing 50, it can prevent the contact between the liquid tin and the air through the anti-oxidation structure 10, reduce the generation of tin slag inside the oxidation protection cover cavity, and reduce the tin slag adsorbed on the transmission bearing 50.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
