Description

Technical Field

[0001] This utility model relates to the field of electronic repair tool technology, specifically to an automatic recycling desoldering strip device. Background Technology

[0002] Desoldering wick (also known as desoldering wire or desoldering cord) is a crucial tool used in electronic repair and soldering processes to remove excess solder. Its core technology is based on capillary action and heat conduction principles. Through the contact between the copper braided strip and molten solder, surface tension and adsorption capacity are used to quickly remove solder residue from the joints. However, traditional desoldering wick requires clamping or holding it with tweezers or similar tools before it can be used, which is cumbersome. Furthermore, the used areas are difficult to dispose of, requiring cutting or disposal, which is also inconvenient. Therefore, there is a need to develop a simpler desoldering wick. Utility Model Content

[0003] To address the aforementioned deficiencies in the prior art, this utility model provides an automatic recycling desoldering tape device. The present utility model provides the following technical solution, including:

[0004] The feeding baffle has a winding mechanism at one end and a pressing head at the other end.

[0005] The outer casing is fitted onto the outside of the feeding baffle and connected to the feeding baffle via a connecting mechanism;

[0006] A propulsion mechanism is located in the middle of the outer casing; the propulsion mechanism is used to control the propulsion of the desoldering strip;

[0007] The desoldering strip is conveyed from the reel mechanism, passes over the feed baffle, turns after passing the pressing head, and returns to the reel mechanism from below the feed baffle, forming a closed loop path.

[0008] Furthermore, the propulsion mechanism includes:

[0009] An opening is located above the outer casing. Two sliding grooves are symmetrically arranged on the inner side of the opening. One end of a slider slides within the sliding groove. A button block is located above the slider, and two hook blocks are symmetrically arranged below the slider. A return spring is also provided within the sliding groove. One end of the return spring is connected to the slider, and the other end is connected to the front end of the inner cavity of the sliding groove. When the button block is pressed, the slider drives the hook blocks to push the desoldering strip forward, and the return spring provides a rebound force.

[0010] Furthermore, the connecting mechanism includes:

[0011] A limiting block is fixedly installed at the front end of the outer shell cylinder. The pressing head is symmetrically provided with limiting grooves corresponding to the limiting block on both sides. The cooperation between the limiting block and the limiting groove is used to limit the lateral displacement of the pressing head. Insert rods are symmetrically arranged on both sides of the end of the feeding baffle. The outer shell cylinder is provided with insertion holes at corresponding positions. The cooperation between the insertion rods and the insertion holes is used to fix the relative position of the feeding baffle and the outer shell cylinder.

[0012] Furthermore, the coil mechanism includes:

[0013] A transparent outer shell is connected to the end of the feeding baffle. Inside the transparent outer shell, two meshing feeding gear disks and receiving gear disks are rotatably provided. A winding rod is fixed coaxially on both the feeding gear disks and the receiving gear disks.

[0014] Furthermore, the upper and lower ends of the feeding baffle are symmetrically provided with a first limiting rod and a second limiting rod. The desoldering strip is transmitted from the winding rod on the feeding gear disk, passes through the first limiting rod, then turns through the pressing head, passes through the second limiting rod and returns to the receiving gear disk.

[0015] Furthermore, a rubber sleeve is fitted on the outer side of the outer shell, and the surface of the rubber sleeve is provided with anti-slip texture for anti-slip and anti-scalding purposes.

[0016] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0017] This invention features a closed-loop desoldering tape design consisting of a feeding gear, a pressing head, and a receiving gear. Users simply align the pressing head with the solder joint and push it back lightly to continuously absorb molten solder. The contaminated section automatically returns to the receiving gear, eliminating the need for manual cutting or replacement of the desoldering tape. This allows for single-handed operation and significantly improves maintenance efficiency. Furthermore, the sliding block and hook of the pushing mechanism, combined with a reset spring, ensure precise and timely advancement of the desoldering tape, preventing jamming or retraction. The lateral limiting design of the limiting block and groove, along with the insertion rod and hole fixing structure of the feeding baffle, ensures a stable connection between the pressing head and the outer casing, preventing displacement or detachment during use.

[0018] The transparent shell and detachable feed baffle design allow users to visually observe the remaining amount of desoldering tape and quickly replace the old tape: simply pull out the feed baffle, open the transparent shell, replace the new tape, and reassemble, significantly reducing maintenance costs and time; the anti-slip rubber sleeve and surface texture design on the outside of the shell not only insulate against heat and prevent burns, but also increase grip friction, avoiding the risk of slipping during high-temperature operation and ensuring safe use.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1 to 6 The technical solution provided by this utility model is: an automatic recycling desoldering tape device, comprising:

[0029] The feeding baffle 1 has a winding reel mechanism at one end and a pressing head 2 at the other end;

[0030] The outer casing 3 is sleeved on the outside of the feeding baffle 1 and connected to the feeding baffle 1 through a connecting mechanism;

[0031] A propulsion mechanism is located in the middle of the outer casing 3; the propulsion mechanism is used to control the propulsion of the desoldering strip 4;

[0032] The desoldering strip 4 is transmitted from the reel mechanism, passes above the feed baffle 1, turns after the pressing head 2, and returns to the reel mechanism from below the feed baffle 1, forming a closed loop path.

[0033] The outer side of the outer shell is also fitted with a rubber sleeve 21, the surface of which is provided with anti-slip texture for anti-slip and anti-scalding purposes.

[0034] In a preferred embodiment, the connecting mechanism includes:

[0035] A limiting block 11 is fixedly installed at the front end of the outer shell cylinder 3. The pressing head 2 is provided with limiting grooves 12 on both sides corresponding to the limiting block 11. The cooperation between the limiting block 11 and the limiting grooves 12 is used to limit the lateral displacement of the pressing head 2.

[0036] And insert rods 19 are symmetrically arranged on both sides of the end of the feeding baffle 1. The outer shell cylinder 3 is provided with a corresponding insertion hole 20. The cooperation between the insert rods 19 and the insertion hole 20 is used to fix the relative position of the feeding baffle 1 and the outer shell cylinder 3.

[0037] In a preferred embodiment, the propulsion mechanism includes:

[0038] An opening 5 is located above the outer casing 3. Two sliding grooves 6 are symmetrically arranged on the inner side of the opening 5. One end of a slider 7 slides in the sliding groove 6. A button block 8 is located above the slider 7. Two hook blocks 9 are symmetrically arranged below the slider 7. A return spring 10 is also provided in the sliding groove 6. One end of the return spring 10 is connected to the slider 7, and the other end is connected to the front end of the inner cavity of the sliding groove 6. When the button block 8 is pressed, the slider 7 drives the hook blocks 9 to push the desoldering strip 4 forward, and the return spring 10 provides a rebound force.

[0039] In a preferred embodiment, the reel mechanism includes:

[0040] A transparent outer shell 13 is connected to the end of the feeding baffle 1. Two meshing feeding gear disks 14 and receiving gear disks 15 are rotatably provided inside the transparent outer shell 13. A winding rod 16 is coaxially fixed on both the feeding gear disks 14 and the receiving gear disks 15.

[0041] The feeding baffle 1 is symmetrically provided with a first limiting rod 17 and a second limiting rod 18 on the upper and lower sides of its end. The desoldering strip 4 is transmitted from the winding rod 16 on the feeding gear disk 14, passes through the first limiting rod 17, then turns through the pressing head 2, passes through the second limiting rod 18 and returns to the receiving gear disk 15.

[0042] In the initial state, the desoldering strip 4 is wrapped around the winding rod 16 of the feeding gear disk 14, and extends to the working surface of the pressing head 2 after being guided by the first limiting rod 17; when the user presses the button block 8 of the push mechanism, the slider 7 moves forward along the sliding groove 6. Since the desoldering strip 4 is made of copper wire, it drives the hook block 9 below to insert into the desoldering strip 4 and pushes the desoldering strip 4 to move towards the pressing head 2, so that the new desoldering section covers the working surface.

[0043] After the button block 8 is released, the reset spring 10 pulls the slider 7 to reset, and the hook block 9 disengages from the desoldering strip 4 to prevent it from retracting. After the dirty section of the desoldering strip 4 is turned by the pressing head 2, it is guided by the second limit rod 18 to the winding rod 16 of the receiving gear disk 15. Through the meshing transmission of the feeding gear disk 14 and the receiving gear disk 15, the dirty section is automatically wound and recycled.

[0044] Limitation and structural stability:

[0045] The pressing head 2 restricts lateral displacement through the cooperation of the limiting block 11 and the limiting groove 12, ensuring that the desoldering strip 4 is always aligned with the solder joint; the insertion rod 19 at the end of the feeding baffle 1 is inserted and fixed to the insertion hole 20 of the outer shell cylinder 3 to prevent the feeding baffle 1 from separating from the outer shell cylinder 3 during operation.

[0046] Desoldering operation procedure:

[0047] The user holds the anti-slip rubber sleeve 21 of the outer casing 3, aligns the pressing head 2 with the solder joint and presses it lightly; when using it, first use a blower to melt the solder in the part that needs to be cleaned, or use a soldering iron to heat the solder joint to melt the solder, and then push the device back to any position. The solder absorber 4 uses capillary action to absorb the molten solder.

[0048] Alternatively, by pressing button block 8, a new section of desoldering strip 4 can be quantitatively advanced, and the dirty section will be automatically recycled into the transparent housing 13. Users can visually observe the remaining amount and determine when to replace it.

[0049] When the desoldering strip 4 is exhausted or needs to be replaced, pull out the insertion rod 19 of the feeding baffle 1 and take out the feeding baffle 1 from the rear end of the outer casing 3; open the transparent outer casing 13, wrap the new desoldering strip 4 around the winding rod 16 of the feeding gear disk 14, pass it through the first limiting rod 17 and the second limiting rod 18 in a closed loop, and fix it to the receiving gear disk 15. After reassembly, it can be used again.

[0050] This invention achieves full automation of the desoldering, recycling, and replacement process through the synergistic effect of mechanical transmission and closed-loop path, significantly reducing manual intervention and improving operational efficiency and safety.

[0051] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
