Description

Technical Field

[0001] This utility model relates to the field of dispensing technology in the 3C industry, specifically to a scraper head wiping mechanism. Background Technology

[0002] In existing technology, after applying adhesive, the residual adhesive on the scraper head needs to be wiped away in preparation for the next application. The traditional wiping method involves wiping the scraper head back and forth with a lint-free cloth, but this method has the following drawbacks:

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0034] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0035] Example 1: The specific structure of this utility model is as follows:

[0036] Please refer to the appendix. Figure 1-3 The present invention relates to a scraper head wiping mechanism, which includes a bracket, a dust-free cloth feeding mechanism, and a clamping mechanism.

[0037] The bracket is an L-shaped bracket, which includes a base plate 1 and an upright plate 2 perpendicularly connected to one side of the base plate 1. A reinforcing rib 16 is provided between the base plate 1 and the upright plate 2. The reinforcing rib 16 is L-shaped, which can increase the rigidity of the L-shaped bracket. One side of the upright plate 2 is the front, and the other side is the back.

[0038] The cleanroom cloth feeding mechanism is located on the support frame, and the cleanroom cloth feeding mechanism includes a feeding section, a receiving section and multiple guide wheels.

[0039] The feeding section has a feeding power source 15 and a feeding wheel 5 that is driven and connected to the feeding power source 15; the feeding power source 15 includes one of a DC motor, a stepper motor and a servo motor. Preferably, the feeding power source 15 is a DC motor, and the DC motor drives the feeding wheel 5 to rotate.

[0040] The receiving section has a receiving power source 17 and a receiving wheel 3 driven by the receiving power source 17; the receiving power source 17 is a stepper motor. The stepper motor drives the receiving wheel 3 to rotate. A clean, lint-free cloth 12 placed on the discharging wheel 5 is received into the receiving wheel 3 after wiping the scraper head 11.

[0041] Multiple guide wheels are rotatably mounted on the bracket. The cleanroom cloth 12 is led out from the feeding wheel 5, passes through the multiple guide wheels, and winds into the receiving wheel 3. The multiple guide wheels include two guide rollers 4 located at the lower left and lower right corners of the feeding wheel 5. One of the guide rollers 4 has a synchronously rotating sensing gear 18 mounted on a rotating shaft extending to the other side of the bracket. A photoelectric sensor 19 is located below the sensing gear 18 and is fixed to the bracket. The photoelectric sensor 19 can sense the number of teeth of the sensing gear 18.

[0042] The plurality of guide wheels also includes two sets of limiting guide rollers 9. The two sets of limiting guide rollers 9 are respectively installed at the upper left and upper right corners of the bracket via limiting plates 20. The height of both sets of limiting plates 20 is adjustable. The limiting plates 20 are provided with vertically oriented oblong holes, which are fixed by bolts and nuts. By adjusting the height of the limiting plates 20, the height of the limiting guide rollers 9 can be adjusted, thereby adjusting the height of the lint-free cloth 12 mounted on the two sets of limiting guide rollers 9, so that the lint-free cloth 12 can better wipe the scraper head 11.

[0043] The clamp mechanism is located on the bracket and has a clamp power unit and a contour clamp 10 driven and connected to the clamp power unit. The contour clamp 10 is arranged opposite to the scraper head 11 and the scraping surface of the contour clamp 10 matches that of the scraper head 11. The path of the cleanroom cloth 12 of the cleanroom cloth feeding mechanism passes through the gap between the contour clamp 10 and the scraper head 11.

[0044] The clamp's power unit is a pneumatic finger cylinder 6, with the driving end of the pneumatic finger cylinder 6 connected to a contour clamp 10 facing upwards. The contour clamp 10 has a V-shaped clamping opening. The V-shaped contour clamp 10 is adapted to the scraping surface of the scraping head 11. After the scraping head 11 finishes scraping the adhesive, it returns to its scraping position, that is, back to directly above the contour clamp 10. The pneumatic finger cylinder 6 drives the V-shaped contour clamp 10 to rise, which in turn moves the lint-free cloth 12 to rise, allowing the lint-free cloth 12 to wipe the bottom and sides of the scraping head 11. During the wiping process of the scraping head 11, it is necessary to stop the movement of the lint-free cloth 12; therefore, a cloth-stopping mechanism is provided on the bracket.

[0045] The scraper head wiping mechanism also includes at least one set of cloth-stopping mechanisms capable of pressing the cleanroom cloth 12 to stop its movement. For example... Figure 1 As shown, two sets of cloth-stopping mechanisms are provided, located on both sides of the support frame. Each cloth-stopping mechanism includes a pen-shaped cylinder 7 mounted on the support frame via a cylinder mounting base 14 and a stop block 8 located at the edge of the support frame. The pen-shaped cylinder 7 drives a pressure block, which points towards the stop block 8, and the cleanroom cloth 12 passes through the gap between the pressure block and the stop block 8. The two sets of pen-shaped cylinders 7 drive the pressure block, causing it to press the passing cleanroom cloth 12 firmly against the stop block 8, preventing the cleanroom cloth 12 from moving and initiating the wiping process.

[0046] A proximity sensor 13 is also installed on the bracket, and the path of the cleanroom cloth 12 after it is led out passes through the sensing end of the proximity sensor 13. The proximity sensor 13 is used to detect whether the cleanroom cloth 12 has been used up.

[0047] In summary, the adhesive scraper head wiping mechanism of this invention can effectively clean the adhesive on the bottom and sides of the adhesive scraper head. During the wiping process, this invention can also stop the lint-free cloth, preventing it from being dragged along.

[0048] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
