Technical Field

[0001] This utility model particularly relates to a tinning machine with a cleaning function used in the tinning process. Background Technology

[0002] Existing soldering machines include a frame with a clamping device slidably mounted on it for holding components to be soldered. A mounting bracket is located on one side of the frame, and this bracket has a receiving groove for holding solder paste. An opening is located at the bottom of the receiving groove, and a sealing plug is fitted onto this opening. To improve sealing, a sealing ring is often fitted onto the sealing plug. A cleaning mechanism is located inside the receiving groove for cleaning. When cleaning is required, water is injected into the groove, the cleaning mechanism cleans the surface of the groove, and then the sealing plug is opened to drain the water through the opening. However, the above structural design has the following problems: the sealing ring itself has a certain degree of elasticity, but over time, it is prone to aging, leading to gaps between the sealing ring and the opening, causing solder paste leakage. Utility Model Content

[0023] A tin-dipping machine with a cleaning function for use in the tin-dipping process, as described in the reference. Figures 1-4 The device includes a frame 1, on which a clamping device 3 for clamping a workpiece 2 to be soldered is slidably mounted. A mounting frame 4 is provided on one side of the frame 1. A receiving groove 5 for holding solder paste is provided on the mounting frame 4. A cleaning mechanism is provided in the receiving groove 5. An opening 6 is provided at the bottom of the receiving groove 5. A sealing plug 7 is matched on the opening 6. An elastic sealing cylinder 8 is assembled on the sealing plug 7. Multiple limiting grooves 81 are provided around the inner side wall of the elastic sealing cylinder 8 towards the sealing plug 7. A water-absorbing expansion body 82 is limited in the limiting groove 81. After absorbing water, the water-absorbing expansion body 82 can press against the sealing plug 7.

[0024] Furthermore, the water-absorbing swelling body 82 is a superabsorbent resin.

[0025] Furthermore, the cleaning mechanism includes a screw 91 disposed in the receiving groove 5, a fixing block 92 connected to the screw 91, and crossbars 93 connected to both sides of the fixing block 92, and a brush cylinder 94 detachably connected to the crossbars 93.

[0026] Furthermore, vertical bars 95 are connected to the upper and lower ends of the crossbar 93, respectively.

[0027] Furthermore, the crossbar 93 is inserted into the brush tube 94.

[0028] Furthermore, a rotary motor is connected to the screw 91.

[0029] The working principle of this utility model is as follows:

[0030] In the tinning process, the workpiece 2 to be tinned is clamped and positioned on the clamping device 3. The clamping device 3 moves the workpiece 2 directly above the receiving groove 5, and then moves the workpiece 2 downwards to complete the tinning operation. The specific structural configuration of the clamping device 3 can be found in [reference needed]. Figure 1 Since the structural fit of this part is not the main design concept of this application, and belongs to the mature technical means in this field, its working principle will not be described in detail here.

[0031] Taking the cleaning mechanism with screw 91 and fixed block 92 as an example, when it is necessary to clean the receiving tank 5, water is injected into the receiving tank 5 and the rotary motor is started. The rotary motor drives the screw 91 to rotate, and the fixed block 92 is connected to the screw 91, so it will drive the fixed block 92 to move in the horizontal direction. The two ends of the fixed block 92 are respectively provided with crossbars 93, and the two sides of the crossbars 93 are detachable brush cylinders 94. So when the screw 91 rotates, it will drive the brush cylinders 94 to clean the inner wall of the receiving tank 5. After cleaning is completed, the sealing plug 7 and the elastic sealing cylinder 8 located at the opening 6 of the receiving tank 5 are opened, and the sewage will be discharged through the opening 6. This application mainly improves the structure of the elastic sealing cylinder 8. Multiple limiting grooves 81 are formed around the inner wall of the elastic sealing cylinder 8, and a water-absorbing swelling body 82 is limited within each limiting groove 81. After absorbing water, the water-absorbing swelling body 82 presses against the sealing plug 7, thus allowing the elastic sealing cylinder 8 to be stably installed on the sealing plug 7. When it is necessary to close the opening 6, the sealing plug 7 is inserted into the opening 6, and the elastic sealing cylinder 8 will fit tightly inside the opening 6. The water-absorbing swelling body 82 allows the elastic sealing cylinder 8 to fit the opening 6 better, reducing the gap between the elastic sealing cylinder 8 and the opening 6, thereby improving the sealing performance. As an embodiment 1, the elastic sealing cylinder 8 is preferably made of rubber, and the water-absorbing swelling body 82 can be made of a highly absorbent resin.

[0032] Based on the above technical solution, regarding the connection method between the brush tube 94 and the crossbar 93, an insertion hole can be opened on the brush tube 94, and the crossbar 93 can be inserted into the brush tube 94. With this design, the brush tube 94 can be disassembled when cleaning is not required, which is very convenient to use.

[0033] Based on the above technical solution, this application also connects vertical rods 95 to the upper and lower ends of the horizontal rod 93 respectively. When the screw 91 drives the fixing block 92 to move in the horizontal direction, the vertical rods 95 can stir the solder paste. This design is intended to make the internal solder powder particles and fluxing material of the solder paste evenly mixed, ensuring the uniformity and consistency of the solder paste, thereby ensuring the soldering effect.

[0034] The soldering machine of this application has an elastic sealing cylinder 8 mounted on the sealing plug 7. The inner sidewall of the elastic sealing cylinder 8 is provided with a plurality of limiting grooves 81 circumferentially facing the sealing plug 7. A water-absorbing expansion body 82 is limited in the limiting groove 81. After absorbing water, the water-absorbing expansion body 82 can press against the sealing plug 7. When it is necessary to close the opening 6, the sealing plug 7 is inserted into the opening 6, and the elastic sealing cylinder 8 will be tightly attached to the opening 6. The water-absorbing expansion body 82 can make the elastic sealing cylinder 8 fit the opening 6 better, reduce the gap between the elastic sealing cylinder 8 and the opening 6, thereby improving the sealing performance and effectively preventing the problem of solder paste leakage.

[0035] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
