[0025] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0026] Please refer to Figures 1 to 3, a double-sided wiping mechanism, comprising a frame 1 and two wiping components symmetrically arranged on the frame 1, the two wiping components each comprising a wiping belt 2, a feeding roller 3, a winding roller 4, a first rotating driving member 5, a second rotating driving member 6 and a pressing component 7, a lifting driving member 71 and a pressing block 72; the first rotating driving member 5 is drivingly connected to the feeding roller 3, the second rotating driving member 6 is drivingly connected to the winding roller 4, the pressing component 7 is arranged between the feeding roller 3 and the winding roller 4, the pressing component 7 comprises a lifting driving member 71 and a pressing block 72 that are drivingly connected; the wiping belt 2 passes through a gap between the two pressing blocks 72, and the two ends of the wiping belt 2 are respectively wound around the feeding roller 3 and the winding roller 4.

[0027] From the above description, it can be seen that the beneficial effect of the utility model is that the structure of the double-sided wiping mechanism is simple and easy to manufacture. A gap is formed between the two wiping belts 2 for the tin sheet 9 to pass through, and the two pressing blocks 72 press the two wiping belts 2 against the two sides of the tin sheet 9 under the drive of the lifting drive member 71, so that the dust or oil on the two sides of the tin sheet 9 is wiped off by the relative movement of the wiping belts 2 and the tin sheet 9, thereby ensuring the welding quality of the chip using the tin sheet 9 for welding.

[0028] Furthermore, the wiping assembly further comprises a guide roller 8 , and the guide rollers 8 are respectively provided on both sides of the pressing block 72 , and the wiping belt 2 passes around the guide rollers 8 .

[0029] As can be seen from the above description, the guide roller 8 is used to guide the direction of the wiping belt 2 so that the wiping belt 2 contacts the side edge of the pressing block 72 and causes wear.

[0030] Furthermore, the thickness of the pressing block 72 gradually decreases from the middle to both sides.

[0031] As can be seen from the above description, the protrusion in the middle of the pressing block 72 can prevent the wiping belt 2 from contacting with the side edges of the pressing block 72 and causing wear.

[0032] Furthermore, the lifting drive member 71 is a cylinder.

[0033] As can be seen from the above description, the lifting drive member 71 is easy to obtain, use and debug.

[0034] Furthermore, the pressing assembly 7 also includes a bracket 73 and a movable plate 74 , the bracket 73 is mounted on the frame 1 , the lifting drive member 71 is mounted on the bracket 73 and is drivingly connected to the movable plate 74 , and the pressing block 72 is mounted on the movable plate 74 .

[0035] It can be seen from the above description that the pressing component 7 has a simple structure and is easy to manufacture.

[0036] Furthermore, the movable plate 74 is provided with a guide post 75 , and the bracket 73 is provided with a guide hole 731 that cooperates with the guide post 75 .

[0037] It can be seen from the above description that the guide column 75 and the guide hole 731 can guide the movement of the movable plate 74 and the pressing block 72 to avoid positional deviation.

[0038] Furthermore, the movable plate 74 is rectangular, and there are four guide posts 75 , which are respectively disposed at four corners of the movable plate 74 .

[0039] Please refer to Figures 1 to 3 The first embodiment of the utility model is: a double-sided wiping mechanism, which is suitable for the field of chip welding and is used to wipe the upper and lower sides of the tin sheet to ensure that the tin sheet is not stained with dust or oil as much as possible, thereby ensuring the quality of chip welding.

[0040] The double-sided wiping mechanism includes a frame 1 and two wiping components symmetrically arranged on the frame 1, and the two wiping components each include a wiping belt 2, a feeding roller 3, a winding roller 4, a first rotating driving member 5, a second rotating driving member 6, a pressing component 7, a lifting driving member 71 and a pressing block 72; the first rotating driving member 5 is drivingly connected to the feeding roller 3, the second rotating driving member 6 is drivingly connected to the winding roller 4, the pressing component 7 is arranged between the feeding roller 3 and the winding roller 4, and the pressing component 7 includes a lifting driving member 71 and a pressing block 72 that are drivingly connected; the wiping belt 2 passes through the gap between the two pressing blocks 72, and the two ends of the wiping belt 2 are respectively wound on the feeding roller 3 and the winding roller 4. The tin sheet 9 passes through the gap between the two wiping belts 2. The two pressing blocks 72 press the two wiping belts 2 against the upper and lower surfaces of the tin sheet 9 respectively. Specifically, the axial directions of the feeding roller 3 and the winding roller 4 are parallel and both are arranged horizontally. The first rotating driving member 5 and the second rotating driving member 6 are both rotating motors. The unwinding roller 3 and the winding roller 4 are symmetrically arranged with the pressing assembly 7 as the center. The wiping belt 2 is preferably made of cloth. The lifting drive member 71 is preferably a cylinder. The pressing block 72 is preferably made of a material with a certain elasticity, such as plastic, rubber or silicone.

[0041] Compared with the ultrasonic cleaning method, using the pressing block 72 to press the wiping belt 2 against the tin sheet 9 for wiping can remove oil and dust more quickly, and the purely mechanical structure is also more convenient for staff to debug.

[0042] The wiping assembly further includes guide rollers 8, which are respectively provided on both sides of the pressing block 72, and the wiping belt 2 passes around the guide rollers 8. Specifically, each wiping assembly has two guide rollers 8, which are symmetrically arranged around the pressing block 72. The axes of the guide rollers 8, the unwinding roller 3 and the winding roller 4 are parallel and all arranged horizontally.

[0043] The thickness of the pressing block 72 gradually decreases from the middle to the two sides. Specifically, the side of the two pressing blocks 72 that are close to each other is set as an arc surface. It is easy to understand that the protrusion of the middle part of the pressing block 72 can prevent the wiping belt 2 from contacting with the side edges of the pressing block 72 to cause wear.

[0044] The pressing assembly 7 further includes a bracket 73 and a movable plate 74. The bracket 73 is mounted on the frame 1. The lifting drive member 71 is mounted on the bracket 73 and is drivingly connected to the movable plate 74. The pressing block 72 is mounted on the movable plate 74. Specifically, the movable plate 74 is rectangular. The pressing block 72 is connected to the movable plate 74 by screws, or the pressing block 72 is connected to the movable plate 74 by adhesive.

[0045] The movable plate 74 is provided with a guide post 75, and the bracket 73 is provided with a guide hole 731 that matches the guide post 75. Specifically, the guide post 75 is cylindrical, and the guide hole 731 is set to be circular corresponding to the guide post 75. There are four guide posts 75, and the four guide posts 75 are respectively set at the four corners of the movable plate 74.

[0046] To sum up, a gap is formed between the two wiping belts of the double-sided wiping mechanism provided by the utility model for the tin sheet to pass through, and the two pressing blocks press the two wiping belts against the two sides of the tin sheet under the drive of the lifting drive component, so that the dust or oil stains on both sides of the tin sheet are wiped off by the relative movement of the wiping belt and the tin sheet, thereby ensuring the welding quality of the chip using the tin sheet.

[0047] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
