Description

Technical Field

[0001] The utility model relates to the technical field of headlight disassembly devices, and more specifically, to a headlight disassembly device. Background Technique

[0002] There are generally two ways to disassemble existing headlights. The first is to use a hot air gun to blow on the hard glue to soften it for disassembly. The second is to put the entire headlight assembly into an oven for heating to soften the hard glue for disassembly.

[0003] The heating range of the hot air gun is small. Restricted by the area of its air outlet, only a small section of the hard glue (generally 3 - 5 cm in length) can be heated at the same time. During the disassembly process, the hot air gun needs to be continuously moved along the contour of the hard glue to heat different positions of the hard glue until the headlight cover is completely separated from the headlight bottom shell. Its disassembly process takes a long time, and the high-temperature hot air blown by the hot air gun is easy to scald the headlight cover because the temperature of the high-temperature hot air is generally above 300 °C, much higher than the melting temperature of the headlight cover (240 - 280 °C).

[0004] The heating range of the oven is large and can heat the entire circle of hard glue, but its heating power is also large and it consumes electric energy. In addition, the disassembly process takes a long time. Depending on the complexity of the headlight structure, it generally takes 30 - 45 minutes. During this period, some of the hard glue has cooled to room temperature and needs to be reheated to achieve damage-free disassembly.

[0005] All in all, the existing headlight disassembly is troublesome, and there are problems of difficult disassembly and inconvenient operation. Content of the Utility Model

[0006] Aiming at the deficiencies of the existing technology, the purpose of the present utility model is to provide a headlight disassembly device, which can solve the problems of difficult disassembly and inconvenient operation existing in the existing headlight disassembly.

[0046] Further, in order to reduce the thermal resistance between the heating wire 2 and the hard glue, so that the heating wire 2 can evenly transfer heat to the hard glue, and to prevent the heating wire 2 from scalding the disassembling personnel at too high a temperature, a heat-conducting back glue layer (not shown in the attached drawing) is provided on the outer wall of the heating wire 2. The heat-conducting back glue layer is tubular and sleeved on the heating wire 2.

[0047] In actual application, the foregoing headlight disassembling device is used to disassemble the headlight. The corresponding headlight disassembling method includes the following steps:

[0048] S1. First, use a cleaner to clean the dust and stains on the outer wall of the headlight, and disassemble after the cleaner dries.

[0049] S2. Place the headlight on the headlight disassembling device for position adjustment and locking (adjust the positions of the support assembly 5, the locking assembly 6, and the ejecting assembly 7 on the mounting plate 4 according to the specific structure of the headlight). After locking, apply a solubilizing agent along the bonding point of the headlight lamp cover and the headlight bottom shell, and let it stand for 5 - 10 minutes.

[0050] S3. During the application of the solubilizing agent, in order for the solubilizing agent to penetrate better, if too much glue is applied at the joint of the headlight lamp cover and the headlight bottom shell, use a tool to clean the glue.

[0051] S4. During the 5 - 10 minutes of standing, use a tool to pry the headlight bottom shell and the glue loose little by little. The entire circumference of the headlight bottom shell should be pried loose, and apply the solubilizing agent while prying loose.

[0052] S5. After a gap appears between the waiting light lamp cover and the lamp housing, stick the heating wire along the outer groove of the lamp housing, and it should be stuck around the outer groove in a circle to heat the lamp housing, with the temperature controlled at 85 ± 10 °C.

[0053] S6. Use an adjustable regulated power supply to control the voltage of the heating wire, with the voltage controlled at 240 - 260 V and the heating time controlled at 15 - 20 minutes.

[0054] S7. When the temperature of the lamp housing reaches 85 ± 10 °C, use the tooling to gently pry loose the lamp housing and the glue bit by bit. The four sides of the lamp housing should be pried loose, and apply the glue solvent while prying loose.

[0055] S8. After the hard glue between the lamp cover and the lamp housing becomes loose, use the tooling to make an opening at the bonding point of the glue between the lamp cover and the lamp housing.

[0056] S9. The size of the opening should be such that the first ejecting component 7 can enter between the lamp cover and the lamp housing, and the first ejecting component 7 drives the lamp cover and the lamp housing to separate. During the separation process, inject the silicone dissolving agent until the lamp cover and the lamp housing are completely separated to the ejecting position of the second ejecting component 7.

[0057] S10. Insert the second ejecting component 7 between the lamp cover and the lamp housing and drive the lamp cover and the lamp housing to continue separating. During the separation process, inject the silicone dissolving agent until the lamp cover and the lamp housing are completely separated to the ejecting position of the next ejecting component 7.

[0058] S11. Use the next ejecting component 7 to repeat the method in step S10 to drive the lamp cover and the lamp housing to continue separating until the lamp cover and the lamp housing are completely separated.

[0059] Apply the above device and method to disassemble the vehicle lamp to solve the problems of difficult disassembly and inconvenient operation existing in the disassembly of the existing vehicle lamp.

[0060] In summary, the present utility model has at least the following beneficial effects: (1) The heating wire 2 is bent into a shape corresponding to the contour of the hard glue and placed around it. Under the control of the adjustable regulated power supply, it can stably heat and soften the hard glue, having the advantages of a wide heating range, low energy consumption, not easily scalding the lamp cover, and not requiring repeated heating during the disassembly process. (2) After the hard glue is softened, by the mutual cooperation of the support component 5, the locking component 6 and the ejecting component 7, the lamp housing and the lamp cover can be quickly separated. (3) The mounting plate 4 can rotate 360° in the horizontal direction around the swing angle component 8, facilitating the disassembler to find a suitable angle to disassemble the vehicle lamp. (4) The swing angle component 8 can rotate at a certain angle in the height direction along the base 1, facilitating the disassembler to further find a suitable angle to disassemble the vehicle lamp.

[0061] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments.
