Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to a device for scraping and cleaning glue on electronic circuit boards. Background Art

[0002] In order to protect the circuit board, it is generally necessary to cover the circuit board with waterproof glue. However, when the operator repairs the circuit board, the operator needs to scrape off the waterproof glue on the circuit board before repairing the components on the circuit board.

[0003] The cleaning process of waterproof glue is usually as follows: the operator first applies banana oil on the waterproof glue on the circuit board to separate the waterproof glue from the circuit board, and then uses a flat spatula to scrape the waterproof glue off the circuit board.

[0004] Regarding cleaning devices for waterproof glue on electronic circuit boards, a search revealed patent publication number CN221063788U, for example, which provides a scraper-type cleaning device for electronic circuit boards. The device comprises a housing, a cavity defined within the housing, an annular groove defined on the outer wall of the housing, a brush positioned within the annular groove, and an opening communicating with the cavity. A flat shovel is fixedly connected to the bottom of the housing, a rotating rod is rotatably connected within the cavity, an arc-shaped block is fixedly connected to the outer wall of the rotating rod, and a sealing member is provided on the housing to seal the cavity. When banana oil is poured into the cavity, the arc-shaped block seals the opening, preventing the banana oil from flowing onto the brush. The rotating rod is rotated to expose the opening, allowing the banana oil in the cavity to flow through the opening onto the brush. This facilitates the operator to apply the banana oil to the waterproof glue on the circuit board using the brush, and then the flat shovel can scoop up the waterproof glue on the circuit board for cleaning, which is convenient and facilitates maintenance personnel in inspecting the circuit board.

[0005] Based on the above search and in combination with the prior art, it was found that the prior art electronic circuit board scraper cleaning devices similar to the above disclosure require manual operation to close and open the opening, and the closing and opening of the opening is relatively cumbersome. Therefore, an electronic circuit board scraper cleaning device is proposed to improve the above problem. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example: Reference Figure 1-5 The electronic circuit board scraping and cleaning device shown includes a first box body 1, a second box body 2 and a protective cover 9.

[0032] The inner side of the first box body 1 is filled with a waterproof adhesive agent, which is preferably conventional banana oil. Of course, the first box body 1 can be made of a material that does not react with the waterproof adhesive agent.

[0033] A smear roller 3 is rotatably mounted at the bottom opening of the first box body 1, and a brush 16 is also mounted on one side of the bottom opening of the first box body 1. The axis of the smear roller 3 is horizontally arranged. Figure 6 As shown, a plurality of grooves 301 are equidistantly arranged on the side end of the coating roller 3, and the plurality of grooves 301 are arranged along the axial direction of the coating roller 3. The coating roller 3 moves in contact with the waterproof glue on the electronic circuit board. The coating roller 3 rotates by utilizing the rolling friction between the coating roller 3 and the waterproof glue on the electronic circuit board, and cooperates with the brush 16 to evenly apply the waterproof glue solvent on the waterproof glue.

[0034] It should be further explained that the width of the groove 301 is smaller than the contact width between the curved surface of one side of the smear roller 3 and the first box body 1. When in use, the smear roller 3 can stop the smearing operation at any position, and the waterproof adhesive agent in the first box body 1 will not continue to overflow, making it more convenient to use.

[0035] Among them, the second box body 2 is fixed to the side end of the first box body 1 away from the brush 16, and a rubber tapping assembly is installed on the inner side of the second box body 2. The rubber tapping assembly includes a knife seat 4 and a plurality of cutting knives 5. The knife seat 4 is installed on the inner side of the second box body 2. The plurality of cutting knives 5 are installed at the lower end of the knife seat 4 at equal distances along the axial direction of the coating roller 3, and the cutting knives 5 extend to the outside of the bottom box opening of the second box body 2. When the waterproof glue agent is applied, the cutting knife 5 is directed in the direction of the overall movement of the equipment. The cutting knife 5 can cut the waterproof glue on the electronic circuit board, so that the waterproof glue agent can penetrate into the waterproof glue, thereby increasing the contact area between the waterproof glue agent and the waterproof glue, accelerating the softening effect of the waterproof glue agent on the waterproof glue, and thus improving the glue removal efficiency.

[0036] Among them, the protective cover 9 is hinged to the lower end of the first box body 1 and can cover the bottom box openings of the first box body 1 and the second box body 2 at the same time. A scraper 10 is fixed to the outer surface of the protective cover 9. When the protective cover 9 is fully opened, the scraper 10 fits into the outer surface of the first box body 1. Specifically, a card block 11 is fixed to the outer wall of one side of the first box body 1, and a card groove 901 is provided on the outer wall of the side of the protective cover 9 close to the first box body 1, which is engaged with the card block 11. When the waterproof adhesive is applied, the scraper 10 is not easy to cause scratches.

[0037] In addition, a fixing block 13 is installed on the outer wall of the protective cover 9 away from the card slot 901, and a fixing bolt 12 that is threadedly engaged with the fixing block 13 is rotatably connected to the outer wall of one side of the second box body 2. After the waterproof glue softens, the protective cover 9 is covered and threadedly fixed with the fixing bolt 12 and the fixing block 13. The softened waterproof glue can be scraped off with a spatula 10.

[0038] Among them, the rubber tapping assembly also includes an adjusting slider 6 and an adjusting screw 7. The adjusting slider 6 and the knife seat 4 are both vertically slidably installed on the inner side of the second box body 2. The adjusting slider 6 is located on the upper side of the knife seat 4, and a compression spring 8 is fixed between the adjusting slider 6 and the knife seat 4. The adjusting screw 7 vertically penetrates the second box body 2 and is rotatably connected to the second box body 2. The lower end thread of the adjusting screw 7 penetrates the adjusting slider 6.

[0039] The coordinated arrangement of the above-mentioned structure enables the operator to adjust the exposed length of the cutting knife 5 according to the actual thickness of the waterproof glue on the electronic circuit board, that is, to adjust the cutting depth of the waterproof glue by the cutting knife 5, which can effectively avoid the cutting depth of the cutting knife 5 being too large and causing damage to the circuit board; specifically, the operator can manually rotate the adjusting screw 7 to move the adjusting slider 6 up and down, thereby adjusting the exposed length of the cutting knife 5.

[0040] In addition, a slope 501 is provided at the bottom end of the cutting knife 5 away from the smear roller 3. The compression spring 8 and the slope 501 on the cutting knife 5 can enable the cutting knife 5 to better avoid the pins of the electronic components on the circuit board, and it is not easy to cause accidental damage to the pins of the electronic components.

[0041] Considering that the glue removal operation may be in a non-horizontal position, in order to ensure that the waterproof glue solution in the first box body 1 can be stably dipped by the smear roller 3, the inner side of the first box body 1 is vertically slidably fitted with an extrusion slider 14, and a compression spring 2 15 is fixed between the extrusion slider 14 and the inner top of the first box body 1. For example, the compression spring 2 15 can be compressed to Figure 4 In the state shown, the extrusion slider 14 cooperates with the compression spring 15 to ensure that the waterproof adhesive solvent is always in contact with the coating roller 3; in addition, it should be noted that the first box body 1 is provided with an air hole (not shown in the figure) to ensure the air pressure balance on the upper and lower sides of the extrusion slider 14, and a solvent replenishing port is provided on the bottom side of the first box body 1, and a sealing plug is provided at the solvent replenishing port. In order to facilitate the operator to observe the remaining amount of solvent inside the first box body 1, the first box body 1 can be set as a transparent box body.

[0042] Of course, the structures on the above-mentioned device that are in contact with the waterproof adhesive agent can be made of materials that do not react with the waterproof adhesive agent, such as conventional polypropylene materials, and the first box body 1 is made of transparent polypropylene material.

[0043] The working principle of the utility model is as follows: the operator holds the cleaning device in hand, and moves the smear roller 3 to the waterproof glue corresponding to the position of the electronic circuit board that needs to be repaired. The rolling friction between the smear roller 3 and the waterproof glue on the electronic circuit board causes the smear roller 3 to rotate, so that the waterproof glue solvent in the first box body 1 is delivered to the waterproof glue by the groove 301 on the smear roller 3, and the waterproof glue solvent is evenly applied to the surface of the waterproof glue by using the brush 16, which is more convenient to use;

[0044] In addition, when the cutting knife 5 is directed toward the direction in which the device as a whole moves and the waterproof adhesive agent is applied, the cutting knife 5 can cut the waterproof adhesive on the electronic circuit board, so that the waterproof adhesive agent can penetrate into the waterproof adhesive, thereby increasing the contact area between the waterproof adhesive agent and the waterproof adhesive, accelerating the softening effect of the waterproof adhesive agent on the waterproof adhesive, and thus improving the adhesive removal efficiency;

[0045] After the waterproof glue softens for a while, close the protective cover 9 and use the fixing bolts 12 and the fixing block 13 to screw together, and then use the spatula 10 to scrape off the softened waterproof glue.

[0046] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
