Description

Technical Field

[0001] This invention relates to the field of vehicle headlight disassembly device technology, and more specifically, to a vehicle headlight disassembly device and a vehicle headlight disassembly method. Background Technology

[0002] There are generally two methods for disassembling existing car lights. The first method is to use a heat gun to blow air onto the hard plastic to soften it and make it removable. The second method is to put the entire car light assembly into an oven to heat it and soften the hard plastic, making it removable.

[0003] The heating range of a hot air gun is small, limited by the area of ​​its air outlet. It can only heat a small section (usually 3-5cm) of hard plastic at a time. During disassembly, the hot air gun needs to be moved along the outline of the hard plastic to heat different parts of the hard plastic until the headlight cover and the headlight base are completely separated. The disassembly process is time-consuming, and the high-temperature hot air blown by the hot air gun can easily burn the headlight cover, because the temperature of the high-temperature hot air is generally above 300℃, which is much higher than the melting temperature of the headlight cover (240-280℃).

[0004] The oven has a large heating range, capable of heating the entire ring of hard plastic, but its heating power is also high, requiring a significant amount of electricity. Furthermore, the disassembly process takes a considerable amount of time, typically 30-45 minutes depending on the complexity of the headlight structure. During this time, some of the hard plastic has cooled to room temperature, requiring reheating for non-destructive disassembly.

[0005] In summary, existing vehicle headlight disassembly devices or methods suffer from difficulties in disassembly and inconvenience in operation. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a vehicle headlight disassembly device. This invention can solve the problems of disassembly difficulties and inconvenient operation of existing vehicle headlight disassembly devices or methods.

[0007] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A vehicle headlight disassembly device includes a base and a heating wire for heating and softening hard plastic; a swing arm truncated cone is hinged to the base, and a mounting plate is rotatably mounted on the swing arm truncated cone. The mounting plate is provided with a plurality of support components for supporting the bottom shell of the vehicle headlight, a plurality of locking components for movably locking the bottom shell of the vehicle headlight, and a plurality of ejection components for driving the headlight cover away from the headlight shell; the base is provided with a swing angle component for adjusting the relative angle between the swing arm truncated cone and the base, and the swing angle component is kinetically connected to the swing arm truncated cone.

[0008] Optionally, the support assembly includes a first support column and a first support fixture adapted to a first force-bearing part on the headlight housing; the lower end of the first support column is detachably connected to the mounting plate, and its upper end is inserted into the first support fixture.

[0009] Optionally, the locking assembly includes a second support column, a second support fixture adapted to a second force-bearing part on the lamp base, and a clamping member for movably pressing the second force-bearing part on the lamp base onto the second support fixture; the lower end of the second support column is detachably connected to the mounting plate, and its upper end is inserted into the second support fixture; the clamping member is fixedly connected to the second support column.

[0010] Optionally, the clamping component includes a corner code plate, a first cylinder, a support, and a locking block; the side wall of the corner code plate is fixedly connected to the second support column, and its top is fixedly connected to the fixed end of the first cylinder; the bottom of the support is fixedly connected to the fixed end of the first cylinder, and its top is hinged to the middle of the locking block; one end of the locking block is hinged to the output shaft of the first cylinder, and its other end movably presses against the second force-bearing part on the bottom shell of the vehicle lamp.

[0011] Optionally, the ejection assembly includes a third support column, a pry bar for inserting into the gap between the headlight base and the headlight cover, and a second cylinder for driving the pry bar to move toward the headlight cover; the lower end of the third support column is detachably connected to the mounting plate, and its upper end is fixedly connected to the fixed end of the second cylinder; the output shaft of the second cylinder is fixedly connected to the pry bar.

[0012] Optionally, the swing arm assembly includes a lead screw, a sleeve fitted on the lead screw, and a handwheel fixedly mounted at the end of the lead screw; both ends of the lead screw are rotatably connected to the base, and the middle part is threadedly connected to the sleeve; the outer wall of the sleeve is provided with a rack portion, which meshes with the gear portion of the swing arm truncated cone for transmission.

[0013] Optionally, the swing arm platform has several angle holes arranged in a circular array at equal intervals, and the mounting plate has at least one pin hole with a positioning pin inserted into it. The positioning pin passes through any angle hole to keep the mounting plate and the swing arm platform in a relatively fixed state.

[0014] Optionally, a thermally conductive adhesive layer is provided on the outer wall of the heating wire.

[0015] Another object of the present invention is to provide a method for disassembling vehicle lights, which uses the aforementioned vehicle light disassembly device to disassemble vehicle lights, and includes the following steps: S1. First, use a cleaning agent to clean the dust and stains on the outer wall of the headlight. After the cleaning agent dries, disassemble it. S2. Place the headlight on the headlight disassembly device, adjust its position and lock it. After locking, apply solvent along the joint between the headlight cover and the headlight base, and let it stand for 5-10 minutes. S3. During the application of solvent, if too much solvent is applied at the junction of the headlight cover and the headlight housing, a tool should be used to clean the adhesive in order to allow the solvent to penetrate better. S4. During the 5-10 minute resting period, use a tool to pry the headlight base and the glue little by little. The entire circumference of the headlight base must be pried loose. Apply solvent while prying. S5. After a gap appears between the headlight cover and the headlight base, attach the heating wire along the outer groove of the headlight base, making sure to attach it around the outer groove to heat the headlight base. The temperature should be controlled at 85±10℃. S6. Use an adjustable regulated power supply to control the voltage of the heating wire, with the voltage controlled at 240-260V and the heating time controlled at 15-20 minutes. S7. When the temperature of the headlight base reaches 85±10℃, use a tool to pry the headlight base and the glue little by little. All four sides of the headlight base should be pried loose. Apply solvent while prying. S8. After the hard glue between the headlight cover and the headlight base becomes loose, use a tool to make an opening at the glue joint between the headlight cover and the headlight base. S9. The size of the opening is sufficient to allow the first ejector component to enter between the headlight cover and the headlight base. The first ejector component drives the headlight cover to separate from the headlight base. During the separation process, silicone solvent is injected until the headlight cover and the headlight base are completely separated to the ejection position of the second ejector component. S10. Insert the second ejector assembly between the headlight cover and the headlight base, and drive the headlight cover and headlight base to continue separating. During the separation process, inject silicone solvent until the headlight cover and headlight base are completely separated to the ejection position of the next ejector assembly. S11. Using the next ejector component, repeat the method in step S10 to drive the headlight cover and headlight base to continue separating until the headlight cover and headlight base are completely separated.

[0016] In summary, the present invention has the following beneficial effects: (1) The heating wire is bent into a shape corresponding to the outline of the hard plastic and placed around it. Under the control of the adjustable regulated power supply, it can stably heat and soften the hard plastic, which has the advantages of wide heating range, low energy consumption, easy to avoid burning the headlight cover, and no need to reheat during disassembly. (2) After the hard plastic is softened, the headlight base and headlight cover can be quickly separated by the cooperation of the support component, locking component and ejection component.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] This invention provides a vehicle headlight disassembly device, such as... Figure 1-4 As shown, it includes a base 1 and a heating wire 2 for heating and softening hard plastic; a swing arm truncated cone 3 is hinged on the base 1, and a mounting plate 4 is rotatably mounted on the swing arm truncated cone 3.

[0024] Specifically, the base 1 is hinged to the bottom of the swing arm frustum 3 via a pin and pin hole or a bearing using a conventional fitting structure, allowing the swing arm frustum 3 to rotate counterclockwise or clockwise by a certain angle (see reference). Figure 3The top of the swing arm frustum 3 is a circular plate, which is rotatably connected to the mounting plate 4 via existing methods such as pin and pin hole engagement or bearing. The mounting plate 4 is a circular plate with numerous threaded holes (not shown in the attached diagram) on its surface. Its diameter is slightly larger than that of the circular plate on the swing arm frustum 3. The two are concentrically arranged with a certain gap to allow the mounting plate 4 to rotate smoothly on the circular plate on the swing arm frustum 3. Multiple support components 5, multiple locking components 6, and multiple ejector components 7 are installed on the mounting plate 4 using existing installation methods such as screws and magnets, depending on the specific location of the headlights. The number of support components 5, locking components 6, and ejector components 7 can be appropriately increased or decreased as needed; in this embodiment, each component is present in pairs. The heating wire 2 is a flexible resistance wire that can be bent into the contour shape of hard plastic to heat and soften it. The heating wire 2 achieves heating through an adjustable and stable power supply (not shown in the attached diagram), and its heating power is controlled by the adjustable and stable power supply.

[0025] The above-described headlight disassembly device places the heating wire 2 around the hard plastic after bending it into a shape corresponding to the outline of the hard plastic. Under the control of an adjustable and regulated power supply, it can stably heat and soften the hard plastic.

[0027] like Figure 4-5 As shown, the first support column 51 is a 40*40mm square aluminum profile. Its lower end is fixed to the mounting plate 4 by multiple corner brackets and screws, and its upper end is inserted into the first support fixture 52. The specific structure of the first support fixture 52 is set according to the structure of different stress-bearing parts on the headlight housing, and is not limited to a certain structure. In addition, the length of the first support column 51 is set according to actual needs, or an adjustable telescopic rod or telescopic component (such as an electric cylinder) can be used instead.

[0028] Furthermore, the locking assembly 6 includes a second support post 61, a second support fixture 62 adapted to the second force-bearing part on the lamp base, and a clamping member 63 for movably pressing the second force-bearing part on the lamp base onto the second support fixture 62; the lower end of the second support post 61 is detachably connected to the mounting plate 4, and its upper end is inserted into the second support fixture 62; the clamping member 63 is fixedly connected to the second support post 61.

Its lower end is fixed to the mounting plate 4 by multiple corner brackets and screws, and its upper end is inserted into the second support fixture 62. The specific structure of the second support fixture 62 is set according to the structure of different stress-bearing parts on the headlight housing, and is not limited to a certain structure. In addition, the length of the second support column 61 is set according to actual needs, or an adjustable telescopic rod or telescopic component (such as an electric cylinder) can be used instead. The clamping member 63 is installed on the upper end of the second support column 61, and presses the stress-bearing parts on the headlight housing located on the second support fixture 62 into the second support fixture 62 by lever engagement.

[0030] Furthermore, the clamping component 63 includes a corner code plate 631, a first cylinder 632, a support 633, and a locking block 634; the side wall of the corner code plate 631 is fixedly connected to the second support column 61, and its top is fixedly connected to the fixed end of the first cylinder 632; the bottom of the support 633 is fixedly connected to the fixed end of the first cylinder 632, and its top is hinged to the middle of the locking block 634; one end of the locking block 634 is hinged to the output shaft of the first cylinder 632, and its other end movably presses against the second force-bearing part on the bottom shell of the headlight.

[0031] like Figure 4 and Figure 6 As shown, the sidewall of the corner code plate 631 is screwed onto the sidewall of the second support column 61, and its top is screwed to the fixed base of the first cylinder 632. A support 633 is screwed onto the upper end of the fixed base of the first cylinder 632 and located around the extension rod, acting as a lever fulcrum. The left end of the locking block 634 is hinged to the extension rod of the first cylinder 632, its middle portion is hinged to the support 633, and its right end is adapted to the second support fixture 62 to flexibly lock the first force-bearing part on the headlight housing. The locking force of the locking block 634 can be adjusted reasonably using the lever effect of the support 633, or a first cylinder 632 with a smaller stroke or locking force can be selected. In another embodiment, the support 633 can be omitted, and the left end of the locking block 634 can be directly welded to the extension rod of the cylinder 632.

[0032] Furthermore, the ejector assembly 7 includes a third support column 71, a pry bar 72 for inserting into the gap between the headlight base and the headlight cover, and a second cylinder 73 for driving the pry bar 72 to move toward the headlight cover; the lower end of the third support column 71 is detachably connected to the mounting plate 4, and its upper end is fixedly connected to the fixed end of the second cylinder 73; the output shaft of the second cylinder 73 is fixedly connected to the pry bar 72.

Its lower end is fixed to the mounting plate 4 by multiple angle brackets and screws, and the upper side wall is fixed to the second cylinder 73 by screws. A pry bar 72 is fixed to the extension rod of the second cylinder 73 by screws. The pry bar 72 is Z-shaped. In addition, the length of the third support column 71 can be set according to actual needs, or an adjustable telescopic rod or telescopic component (such as an electric cylinder) can be used instead. Furthermore, in order to obtain a more controllable ejection force, a miniature electric cylinder can be used instead of the second cylinder 73.

[0034] Furthermore, the swing arm assembly 8 includes a lead screw 81, a sleeve 82 sleeved on the lead screw 81, and a handwheel 83 fixedly disposed at the end of the lead screw 81; both ends of the lead screw 81 are rotatably connected to the base 1, and the middle part is threadedly connected to the sleeve 82; the outer wall of the sleeve 82 is provided with a rack portion 821, and the rack portion 821 meshes with the gear portion 31 of the swing arm truncated cone 3 for transmission.

[0035] like Figure 3 and Figure 8-9 As shown, the base 1 has a cuboid cavity for housing the lead screw 81, the lead sleeve 82, and the gear section 31 of the swing arm frustum 3. Both ends of the lead screw 81 are rotatably connected to the base 1 via bearings. A handwheel 83 is installed on the left side of the lead screw 81 to facilitate its rotation. When the handwheel 83 is turned, the lead sleeve 82 slides left and right within the cuboid cavity. The rack section 821 at the upper end of the lead sleeve 82 drives the gear section 31 of the swing arm frustum 3 to rotate, thereby causing the swing arm frustum 3 to swing left and right.

[0036] Furthermore, the swing arm truncated cone 3 has several angle holes 32 arranged in a circular array at equal intervals, and the mounting plate 4 has at least one pin hole. A positioning pin 41 is inserted into the pin hole.

[0037] like Figure 4 As shown, twenty angle holes 32 are evenly spaced on the circular plate of the swing arm frustum 3. A pin hole (not shown in the attached figure) is opened on both opposite sides of the mounting plate 4. The positioning pin 41 can pass through any angle hole 32, so that the mounting plate 4 and the circular plate of the swing arm frustum 3 can be in a relatively fixed state according to the actual position requirements.

[0038] Furthermore, in order to reduce the thermal resistance between the heating wire 2 and the hard adhesive, so that the heating wire 2 can transfer heat evenly to the hard adhesive, and to prevent the heating wire 2 from burning the disassembly personnel with excessively high temperature, a thermally conductive adhesive layer (not shown in the attached figure) is provided on the outer wall of the heating wire 2. The thermally conductive adhesive layer is tubular and is sleeved on the heating wire 2.

[0039] A method for disassembling a vehicle headlight, characterized by using the aforementioned vehicle headlight disassembly device to disassemble the headlight, includes the following steps: S1.

Place the headlight on the headlight disassembly device and adjust and lock its position (adjust the position of the support component 5, locking component 6, and ejection component 7 on the mounting plate 4 according to the specific structure of the headlight). After locking, apply solvent along the joint between the headlight cover and the headlight bottom shell and let it stand for 5-10 minutes. S3. During the application of solvent, if too much solvent is applied at the junction of the headlight cover and the headlight housing, a tool should be used to clean the adhesive in order to allow the solvent to penetrate better. S4. During the 5-10 minute resting period, use a tool to pry the headlight base and the glue little by little. The entire circumference of the headlight base must be pried loose. Apply solvent while prying. S5. After a gap appears between the headlight cover and the headlight base, attach the heating wire along the outer groove of the headlight base, making sure to attach it around the outer groove to heat the headlight base. The temperature should be controlled at 85±10℃. S6. Use an adjustable regulated power supply to control the voltage of the heating wire, with the voltage controlled at 240-260V and the heating time controlled at 15-20 minutes. S7. When the temperature of the headlight base reaches 85±10℃, use a tool to pry the headlight base and the glue little by little. All four sides of the headlight base should be pried loose. Apply solvent while prying. S8. After the hard glue between the headlight cover and the headlight base becomes loose, use a tool to make an opening at the glue joint between the headlight cover and the headlight base. S9. The size of the opening is sufficient to allow the first ejector component 7 to enter between the headlight cover and the headlight base. The first ejector component 7 drives the headlight cover to separate from the headlight base. During the separation process, silicone solvent is injected until the headlight cover and the headlight base are completely separated to the ejection position of the second ejector component 7. S10. Insert the second ejector assembly 7 between the headlight cover and the headlight base, and drive the headlight cover and the headlight base to continue separating. During the separation process, inject silicone solvent until the headlight cover and the headlight base are completely separated to the ejection position of the next ejector assembly 7. S11. Using the next ejector component 7, repeat the method in step S10 to drive the headlight cover and headlight base to continue separating until the headlight cover and headlight base are completely separated.

Under the control of the adjustable regulated power supply, it can stably heat and soften the hard plastic, which has the advantages of wide heating range, low energy consumption, easy to avoid burning the headlight cover, and no need to reheat during disassembly. (2) After the hard plastic is softened, the headlight base and headlight cover can be quickly separated by the cooperation of the support component 5, the locking component 6 and the ejection component 7.
