Description

Technical Field

[0001] This invention relates to the field of surge protector manufacturing technology, specifically to a cable end treatment device for a circuit board before wave soldering. Background Technology

[0002] Surge protectors, also known as lightning arresters, surge protectors, electric surge protectors, overvoltage protectors, etc., mainly include power surge protectors and signal surge protectors. Surge protectors use modern electrical and other technologies to prevent damage to equipment struck by lightning. The lightning energy absorption in surge protectors is mainly achieved by zinc oxide varistors and gas discharge tubes.

[0003] The production process of surge protectors typically requires a large number of wires. The connection between these wires and the surge protector circuit board is usually achieved through wave soldering. This necessitates certain treatment of the wires to facilitate easy insertion into the circuit board and subsequent easier soldering during wave soldering. Existing methods typically involve manually applying flux and tin to the ends, which is cumbersome. Therefore, this paper proposes a cable end treatment device for the circuit board before wave soldering to address the aforementioned problems. Summary of the Invention

[0038] In the embodiments, by Figure 1-7 The present invention provides a cable end treatment device for a circuit board before wave soldering.

[0039] The transmission belt 4 is composed of multiple transmission units that are hinged together. The transmission unit includes a trapezoidal block 41.

[0040] Furthermore, the feeding component 7 includes a feeding box 71 fixed to the top of the base 1. A gradient funnel 72 is connected to the left side of the feeding box 71. The width of the gradient funnel 72 narrows from the right side to the left side. A vibration motor 73 located inside the feeding box 71 is fixedly installed at the bottom of the gradient funnel 72.

[0041] The beneficial effect of adopting the above-mentioned further solution is that the setting of the component can limit the wire that arrives on its left side, so that the end of the wire can be easily processed when it passes through the subsequent component.

[0042] Furthermore, the kneading component 8 includes a C-shaped frame 81 fixed to the front side of the bracket 6. A cylinder 82 with a telescopic end extending to its inner side is fixedly installed on the top of the C-shaped frame 81.

[0044] Furthermore, a rigid plastic plate is provided inside the rubbing pad 83, and the output end of the cylinder 82 is fixedly connected to the rigid plastic plate.

[0046] Furthermore, the flux spraying component 9 includes a liquid box 91 fixed to the top of the base 1, a connecting plate 92 fixedly installed on the inner bottom wall of the liquid box 91, a spraying frame 93 fixedly installed on the top of the connecting plate 92, a circulating pump 94 fixedly installed on the front side of the connecting plate 92 with its water outlet communicating with the spraying frame 93 and its water inlet extending into the liquid box 91, and a nozzle 95 fixedly installed on the bottom of the spraying frame 93 located behind the connecting plate 92.

[0047] The beneficial effect of adopting the above-mentioned further solution is that the setting of this component allows the flux to be sprayed in a cyclic manner, making the application of flux simpler.

[0048] Furthermore, there are multiple nozzles 95 that are equidistantly distributed at the bottom of the connecting plate 92, and water pipes are connected to both ends of the circulating pump 94. The circulating pump 94 is connected to the spray frame 93 through the water pipes.

[0050] Furthermore, a sensor group is installed inside the liquid box 91. The sensor group consists of multiple liquid level sensors distributed at equal intervals. A tri-color LED light is fixedly installed on the front side of the liquid box 91.

[0051] The advantage of adopting the above-mentioned further solution is that this setting can conveniently monitor the flux balance and remind workers to replenish the flux in a timely manner.

[0052] Furthermore, the tin-coating component 10 includes a tin box 101 fixed to the top of the base 1, a heating block 102 fixedly installed on the inner bottom wall of the tin box 101, a conductive tray 103 in contact with the heating block 102 fixedly installed on the inner bottom wall of the tin box 101, and a support rod 104 fixedly installed between the left and right inner walls of the tin box 101.

[0053] The advantage of adopting the above-mentioned further solution is that the component can be positioned so that one end is supported when the wire arrives, while the other end falls into the soldering process, which allows for convenient self-soldering.

[0054] Furthermore, the support pole 104 is inclined and has an anti-slip pad on the outside, and the support pole 104 is set with the left side higher than the right side.

[0055] The beneficial effect of adopting the above-mentioned further solution is that the anti-slip pad can prevent the wire from falling into the box due to the slippery support pole.

[0056] Specifically, the left side of the bracket 6 should be located above the solder box 101 and to the left of the leftmost end of the conveyor belt 4. Meanwhile, the distance from the right side of the bracket 6 to the leftmost end of the conveyor belt 4 can be adjusted according to the production situation. This can be used to address the impact of whether the flux needs to be air-dried or the evaporation rate on the overall processing.

[0057] Specifically, the front side of the bracket 6 can be fixed with fasteners to the drying assembly and the straightening assembly. The drying assembly consists of a fan with the airflow direction towards the conductor and a heating wire located at its air inlet. The straightening assembly consists of a C-shaped straightening block. The straightening assembly should be located between the kneading assembly 8 and the flux spraying assembly. The distance between the upper and lower inner walls of the C-shaped straightening block should correspond to the diameter of the cable core. The drying assembly should be arranged on the left side of the flux spraying assembly.

[0058] Working principle:

[0059] When the ends of the wire need to be processed, the staff can place the wire to be processed directly into the feed box 71. At this time, the wire can start to move towards the bracket 6 under the influence of gravity and vibration motor 73. During the movement, as the gradual funnel 72 begins to narrow, the wire is aligned when it reaches the bracket 6.

[0060] After the wire arrives on the bracket 6, the transmission unit can capture the circular wire through its arc groove 42, causing it to roll to the left. During the rolling process, since the transmission unit contacts the wire at the main contact ball 46 and the auxiliary contact ball 47, the impact on the wire can be minimized. At the same time, since the transmission unit is equipped with a spring 48 and a square ring 45, it can make adaptive adjustments when facing wires of different diameters.

[0061] When the wire moves to the kneading component 8, the proximity switch 84 senses the arrival of the wire and controls the cylinder 82 to push the upper kneading pad 83 downward to press the end of the wire. Since the wire moves to the left in a rolling manner, it can be twisted when it is pressed, and its end can be twisted.

[0062] When the wire reaches the flux spraying component 9 after being twisted, the circulation pump 94 pumps the flux inside the liquid box 91 to the spray frame 93 and sprays it out through the nozzle 95. The surface of the wire passing through this point will be covered with the sprayed flux, and the excess flux will drip into the liquid box 91 for recycling.

[0063] After being dipped in flux, the wire continues to move to the left and is pushed into the tinning component 10 by the wire coming from behind. At this time, the side dipped in solder resist will fall directly into the tin box 101 to complete the tinning process since there is no obstruction. The other end is blocked by the bracket 104 to prevent the entire wire from being immersed in the tin box 101. This also makes the wire easy to pick up and does not require tinning. After a certain amount has been accumulated, the operator can take it out. In this way, the flux dipping and tinning operation of one end of the wire can be completed.

[0064] After the above operations are completed, a second device can be set up. The untinned end of the wire is placed in front and put into the feed box 71. Then the flux dipping and tinning operation of the other end can begin, which is more convenient. At the same time, if this device is only used as a material preparation device, the wires that have been processed at one end can be collected and put into the second process after turning them over. This completes the processing of both ends. In this way, only one device is needed to complete the processing of both ends, which is more convenient.

[0065] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
