Description

Technical Field

[0001] The utility model relates to the field of maintenance equipment, in particular to a steel wire winding structure and an electric separation handle. Background Art

[0002] Smartphones are widely used electronic products in modern times, and the outer screen of mobile phones is fragile, so it is easy to cause the outer screen to break due to improper use, so it needs to be replaced. With the improvement of production technology, the outer screen and the inner screen of most smartphone screens are currently made of a new type of OCA (special adhesive for bonding transparent optical components) double-sided dry glue bonding technology to bond the inner and outer screens, thereby greatly improving the overall safety, reliability, durability and aesthetics of the mobile phone display. Although the physical properties of this OCA dry glue are very stable at room temperature, as the temperature gradually increases, its physical properties will gradually change, that is, the adhesion will gradually weaken. Based on this feature, there are various styles on the market, which use a vacuum pump to adsorb the heating platform of the screen to assist in the separation of the inner and outer screens of the mobile phone display. The process is: first, the screen assembly must be removed from the phone, because the screen has display cables or touch cables connected to the motherboard, and in order to avoid cutting or pulling the cables, the screen must be removed to separate the inner and outer screens; then it is adsorbed on a preheated heating platform for heating, and then the OCA dry glue layer is cut by hand-pulling steel wire or electric equipment to separate the inner and outer screens. This method of manually separating OCA dry glue firstly has the risk of scalding the hands by the heating platform; secondly, it is difficult to accurately grasp the separation force manually, resulting in the inner screen being cut; thirdly, this manual operation requires a certain amount of work experience to complete well, which has become a threshold for newcomers to find employment; finally, this manual operation is labor-intensive, so the efficiency is low, which is not conducive to the work of replacing the outer screens of mobile phones in batches. However, the method of separating OCA dry glue with CNC equipment is relatively costly and has a high entry threshold. In addition, a certain tension needs to be applied to the steel wire during operation. Since the steel wire is very thin, it is easy to break. The existing steel wire winding structure generally adopts a method in which glue is provided on the connecting hole or the winding column. Because the steel wire winding structure is in the equipment and the connecting hole remains unchanged, the efficiency of reinstalling the steel wire after the steel wire is broken is low. When using the glue method, the glue is easily covered. When the glue is covered, the steel wire cannot be quickly reinstalled, and the efficiency of reinstalling the steel wire is unstable.

DETAILED DESCRIPTION

[0041] The technical solution of this article will be further described in detail below in conjunction with the accompanying drawings.

[0042] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0043] Reference Figure 1-5 The utility model proposes a wire winding structure 1, comprising a base 11, an inner limiting ring 12, an outer connecting ring 13 and an inner rubber pad 14; the base 11 comprises a winding column 111 and an end limiting ring 112, the end limiting ring 112 is arranged at one end of the winding column 111; the inner limiting ring 12 is sleeved on the other end of the winding column 111; the outer connecting ring 13 is detachably connected to the other end of the winding column 111; the inner rubber pad 14 is made of flexible material and is arranged between the inner limiting ring 12 and the outer connecting ring 13.

[0044] Specifically, in some embodiments, during the separation of the OCA dry glue, the steel wire winding structure 1 rotates, one steel wire winding structure 1 winds the steel wire, and the other steel wire winding structure 1 releases the steel wire, so that the steel wire cuts the OCA dry glue. When the steel wire breaks, the steel wire is manually pressed between the inner rubber pad 14 and the inner limit ring 12 or between the inner rubber pad 14 and the outer connecting ring 13, and the steel wire is fixed by the pressure and friction of the inner rubber pad 14 on the steel wire. Then, as the steel wire winding structure 1 rotates, the winding column 111 winds the steel wire so that the steel wire is on the outside of the winding column 111. The steel wire is firmly connected to the winding column 111 by forming a loop and mutual extrusion, and it is very convenient to reinstall the steel wire. After the steel wire is firmly wound around the outside of the winding column 111 by winding, there is no need to continue to fix it between the inner rubber pad 14 and the inner limit ring 12 or between the inner rubber pad 14 and the outer connecting ring 13. Therefore, when necessary, the previously fixed steel wire end can be taken out and the new steel wire end can be fixed. There is no situation where the steel wire end cannot be fixed due to lack of space. The fixation of the steel wire end can be continued, and the efficiency of reinstalling the steel wire is stable.

[0045] In some embodiments, the flexible material used for the inner rubber pad 14 can be a soft and elastic material such as silicone, rubber, etc.; in some embodiments, the inner limit ring 12 is an aluminum ring, which is not only easy to produce and process, but also the hardness of aluminum is lower than that of steel. The inner limit ring 12 is less likely to damage the steel wire, and the outer connecting ring 13 can be a steel ring with high strength and not easy to wear. The outer connecting ring 13 is more firmly connected to the winding column 111; in some embodiments, the base 11 is an integral component; in some embodiments, the winding column 111 and the end limit ring 112 are detachable.

[0046] Furthermore, in some embodiments, the radius of the winding column 111 gradually decreases from one end to the other end.

[0047] Specifically, the gradually decreasing radius from one end of the winding column 111 to the other end can form a slope on the surface of the winding column 111, making it easy to remove the steel wire wrapped around the outside of the winding column 111; in some embodiments, the steel wire is not recycled, and the easy removal of the steel wire can facilitate the maintenance of the state of the steel wire winding structure 1 so that it can be used continuously.

[0053] Further, refer to Figure 4 In some embodiments, the winding column 111 is provided with a transmission hole extending axially therethrough; the driving rod 22 includes a rotating portion 221 and a driving portion 222, the rotating portion 221 and the driving portion 222 are fixedly connected, and the driving portion 222 passes through the transmission hole and is transmission-connected to the winding column 111.

[0054] Specifically, the rotating portion 221 is cylindrical, which maintains the stable rotation of the driving rod 22.

By triggering the slow-turn button 52, the speed of the motor 3 can be gradually increased; by triggering the fast-turn button 51, the motor 3 can directly reach the designed maximum speed; by controlling the speed of the motor 3, the speed of the steel wire movement can be controlled, which can better cooperate with the user to separate the OCA dry glue; it should be said that the existing method of separating OCA dry glue, under heating, first cuts the OCA dry glue by quickly moving the steel wire, and then slows down the speed of the steel wire to consolidate the cutting effect, thereby completing the separation of the screen.
