Description

Technical Field

[0001] This invention relates to the field of lamp cover manufacturing fixtures, and more particularly to a fixture for manufacturing lamp covers for new energy vehicles. Background Technology

[0002] New energy vehicle lamp covers are not only functional shells that protect the light source and optimize light efficiency, but also intelligent interactive carriers that integrate aerodynamics and aesthetic design. In their production process, the painting process directly determines the light transmittance, weather resistance, and the exquisite texture of the final lamp cover. In the lamp cover painting process, specific fixtures are needed to fix the lamp cover to maintain its stability during the painting process. Existing fixtures mainly use contouring fixtures, which can perfectly match the edge shape of a specific lamp cover, thereby maintaining the stability of the lamp cover during painting. However, since the contouring fixtures are designed for a single lamp cover specification, when switching lamp cover specifications on the production line, the fixtures must be replaced and reinstalled and adjusted simultaneously. This results in the need to equip multiple specifications of contouring fixtures. For factories that can produce multiple lamp covers on a single production line, the large number of contouring fixtures undoubtedly increases production costs. Summary of the Invention

[0003] This invention provides a fixture for producing lamp covers for new energy vehicles, overcoming the disadvantage of high production costs associated with existing conforming fixtures used in the lamp cover spraying process.

[0004] The technical implementation of the present invention is as follows: a fixture for producing lamp covers for new energy vehicles, comprising: a mounting frame, wherein the mounting frame is provided with two main slide rails, and each of the two main slide rails is provided with a support unit for supporting and positioning the lamp cover; the support unit includes: two sets of main sliders, each set of main sliders having two centrally symmetrically distributed sliders, all of the main sliders being slidably connected to the corresponding main slide rails, a support tube being provided above the main slide rails, the support tube being used to provide support for the lamp cover, two symmetrically distributed hinged parts being provided on the lower side of the support tube, each hinged part being hinged to one of the two main sliders in the corresponding set of main sliders by a hinge strip, two symmetrically distributed sliding grooves being provided on the support tube, a limiting notch being slidably connected within the sliding groove, the limiting notch being used to limit the lamp cover, and a locking component being provided within the support tube for locking the relative positions of the support tube, the hinge strip, and the limiting notch.

[0005] Furthermore, the locking assembly includes: two symmetrically distributed end caps, each threadedly connected to the two ends of the corresponding support tube; the two end caps are rotatably connected to a transmission component; a fixed plate is provided in the middle of the support tube; a movable plate is provided near the fixed plate of the transmission component; the movable plate passes through the support tube; the transmission component is embedded with two symmetrically distributed support arc strips and two symmetrically distributed elastic arc strips; both the support arc strips and the elastic arc strips are located inside the support tube and in contact with the support tube; and the support arc strips are in contact with the corresponding elastic arc strips.

[0006] Furthermore, a protrusion is provided on the inner side of the limiting ring. The protrusion slides within the corresponding sliding groove and passes through the corresponding support tube. The shortest distance between the protrusion and the axis of the corresponding support tube is less than the inner diameter of the support tube. The shortest distance between the hinge strip and the axis of the corresponding support tube is less than the inner diameter of the support tube. The elastic arc strip is used to compress the corresponding protrusion and the corresponding hinge strip.

[0007] Furthermore, the protrusion is provided with equally spaced grooves on the side near the axis of the supporting tube, and the hinge strip is provided with equally spaced arc-shaped grooves near the position corresponding to the hinge. The grooves on the protrusion and the grooves on the hinge strip are both used for the corresponding elastic arc strip to be embedded.

[0008] Furthermore, the hinge strip is provided with an arc-shaped inclined surface near the position corresponding to the hinge portion, and the protrusion is provided with two symmetrically distributed strip-shaped inclined surfaces on the side near the axis of the support tube. Both the arc-shaped inclined surface of the hinge strip and the strip-shaped inclined surface of the protrusion are used to guide the deformation of the corresponding elastic arc strip.

[0009] Furthermore, the limiting ring is threadedly connected to a threaded ring, and the limiting ring is slidably connected to an adjusting ring. The threaded ring is used to compress the corresponding adjusting ring. Two corresponding adjusting rings on the same support tube are located between the two threaded rings. Support bars are provided on the opposing sides of the two corresponding adjusting rings on the same support tube. A guide post is embedded in the limiting ring near the corresponding support post. The guide post is used to support the corresponding support post. An elastic strip is fixed between the support post and the corresponding limiting ring.

[0010] Furthermore, the minimum distance between two corresponding support bars on the same support tube but different limiting rings is less than the spacing between the two limiting rings.

[0011] Furthermore, the mounting frame is fixedly connected to two symmetrically distributed secondary slide rails, and the secondary slide rails are slidably connected to two secondary sliders. The two secondary sliders are respectively fixedly connected to the corresponding main slide rails, and the movement path of the secondary sliders is perpendicular to the movement path of the main sliders.

[0012] Furthermore, the mounting frame is fixedly connected to a positioning frame, and the main slide rail on one side is fixedly connected to an L-shaped frame. An mounting plate is provided between the L-shaped frame and the positioning frame, and connecting strips are hinged between the positioning frame and the L-shaped frame and the mounting plate, respectively.

[0013] Furthermore, the positioning frame is fixedly connected to a limiting frame, which is used to limit the extreme position of the mounting plate. The limiting frame is made of ferromagnetic material, and the mounting plate is embedded with magnets.

[0014] Compared with the prior art, the present invention has the following advantages: The present invention causes the corresponding hinge strip to swing by moving the main slider, thereby adjusting the axial tilt of the support tube. By controlling the tilt of the support tube and the distance between two adjacent limiting rings, the two support tubes provide four-point stable support for the lampshade. Combined with the distance between two adjacent limiting rings to restrict the position of the lampshade, it can not only provide stable support and limit for the lampshade, ensuring the stability of the lampshade during spraying, but also adapt to lampshade of various specifications. When changing the specifications of the lampshade to be sprayed, only the shape of the fixture needs to be adjusted without changing the fixture, thus reducing production costs.

[0015] By using two support tubes to lift and limit the missing ring, it can not only adapt to lamp covers of different specifications, but also better accommodate the positional deviation of the lamp cover during transportation between different processes. The lamp cover's tilted weight causes it to adjust its position relative to the fixture, which helps to maintain the consistency of the spraying effect of lamp covers of the same specification.

[0016] By adjusting the relative positions of the adjusting ring and the limiting ring, the curvature of the support strip end is changed, thereby altering the length of the elastic strip. This allows for better adaptation to the position and thickness of the lampshade flange, while minimizing obstruction of the lampshade and ensuring optimal coating results. By setting the support strip to extend beyond the limiting ring, the contact area with the lampshade edge is reduced, accommodating situations where the lampshade edge and the limiting ring end face are not parallel. This ensures the lampshade is positioned correctly while minimizing the impact on its final movement, thus maintaining consistent coating positions for lampshades of uniform specifications.

[0017] By using a robotic arm to transfer the lampshade, the distance between the two support tubes is reduced after the lampshade is placed on them. This actively changes the position of the lampshade, which improves the reliability of the lampshade position adjustment compared to the method of sliding the lampshade by its own weight. At the same time, it can clamp and fix the lampshade flange after the lampshade is placed on the two support tubes, thereby improving the stability of the lampshade. Attached Figure Description

Detailed Implementation

[0020] To make the above features and advantages of the present invention more readily understood, specific embodiments are described below in conjunction with the accompanying drawings, but the present invention is not limited thereto.

[0021] Example 1

[0022] This embodiment discloses a fixture for producing lamp covers for new energy vehicles, which solves the problem of high production costs caused by the need for various specifications of conforming fixtures in the prior art.

[0023] It is important to understand that, in order to enhance their aesthetics, the headlight covers of existing new energy vehicles are slender and streamlined, gradually narrowing from the middle to both ends, resembling the shape of a willow leaf. Furthermore, the transition sections at both ends of the headlight cover are not symmetrical, typically exhibiting a shorter transition section and a longer transition section. This means that the center of gravity is usually located within the longer transition section.

[0024] See Figures 1 to 5 A fixture for producing lamp covers for new energy vehicles includes: a mounting frame 1, which has two main slide rails 2, each of which is equipped with a support unit for supporting and positioning the lamp cover; the support unit includes two sets of main sliders 3 symmetrically distributed on the left and right, with two sliders 3 centrally symmetrically distributed in each set, all of which are slidably connected to the corresponding main slide rails 2; a support tube 4 is provided above the main slide rails 2 to provide support for the lamp cover; and two hinge parts 401 symmetrically distributed on the lower side of the support tube 4 are provided, which are connected to the two sets of main slide rails 2. The sliders 3 are one-to-one, and the hinge part 401 is hinged to two of the two main sliders 3 in the corresponding set of main sliders 3 with hinge strips 5. The support tube 4 is provided with two sliding grooves 402 that are symmetrically distributed on the left and right. The sliding grooves 402 are connected to the limiting rings 6 for limiting the sliding connection. The limiting rings 6 are used to support the lamp cover flange and limit the lamp cover. The support tube 4 is provided with a locking component for locking the relative position of the support tube 4, the hinge strips 5 and the limiting rings 6. There is friction between the main slider 3 and the main slide rail 2 to maintain the stability of the fixture shape when there is no external force during the fixture change.

[0025] The above setup enables the corresponding hinge bar 5 to swing as the main slider 3 moves, thereby adjusting the axial tilt of the support tube 4. By controlling the tilt of the support tube 4 and the spacing between two adjacent limiting rings 6, the two support tubes 4 provide four-point stable support for the lampshade. Combined with the spacing between the two adjacent limiting rings 6 to restrict the position of the lampshade, it not only provides stable support and limiting for the lampshade, ensuring its stability during spraying, but also adapts to lampshade specifications. When switching the specifications of the lampshade to be sprayed, only the shape of the fixture needs to be adjusted without replacing the fixture, thus reducing production costs. The method of using two support tubes 4 to lift and limiting with limiting rings 6 not only adapts to lampshade specifications, but also better accommodates the positional shift of the lampshade during transport between different processes. The lampshade's own weight in the tilted state causes it to adjust its position relative to the fixture, which helps maintain the consistency of the spraying effect for lampshades of the same specification.

[0026] See Figures 3 to 6 The locking assembly includes two symmetrically distributed end caps 7, which are threaded to the two ends of the corresponding support tube 4. The two end caps 7 are rotatably connected to the transmission component 8. A fixed plate 403 is provided in the middle of the lower side of the support tube 4. A movable plate 801 is provided near the fixed plate 403 of the transmission component 8. The movable plate 801 passes through the support tube 4. The transmission component 8 is embedded with two symmetrically distributed support arc strips 9 and two symmetrically distributed elastic arc strips 10. The support arc strips 9 and elastic arc strips 10 are both located inside the support tube 4 and in contact with the support tube 4. The support arc strips 9 are in contact with the corresponding elastic arc strips 10. The support arc strips 9 are made of metal and are used to provide support for the transmission component 8 and help maintain the coaxial state of the transmission component 8 and the support tube 4. The elastic arc strips 10 are made of elastic material, specifically elastic rubber, and are used to limit the hinge strip 5 and the limiting ring 6 through the friction generated by compression.

[0027] The above setup enables the contact state between the hinge bar 5 and the limiting ring 6 and the elastic arc bar 10 to be changed by the rotation of the transmission component 8, thereby controlling the limiting state of the elastic arc bar 10 on the hinge bar 5 and the limiting ring 6. In this way, the shape of the fixture can be unlocked and fixed by rotating the transmission component 8 during shape change, improving the convenience of shape change.

[0028] See Figures 4 to 7 A protrusion 601 is provided on the inner side of the limiting ring 6. The protrusion 601 slides within the corresponding sliding groove 402. The protrusion 601 passes through the corresponding support tube 4. The side of the protrusion 601 closest to the axis of the corresponding support tube 4 has equally spaced grooves. The shortest distance between the protrusion 601 and the axis of the corresponding support tube 4 is less than the inner diameter of the support tube 4. The shortest distance between the hinge strip 5 and the axis of the corresponding support tube 4 is less than the inner diameter of the support tube 4. The elastic arc strip 10 is used to compress the corresponding protrusion 601 and the corresponding hinge strip 5. The hinge strip 5 has equally spaced arc-shaped grooves near the position of the corresponding hinge part 401. The grooves on the protrusion 601 and the hinge strip 5 The grooves on the upper part are all used for the corresponding elastic arc strips 10 to be embedded, so that the elastic arc strips 10 can be embedded in the grooves of the protrusions 601 and the hinge strips 5, thereby enhancing the friction when the protrusions 601 and the hinge strips 5 contact the elastic arc strips 10; the upper part of the hinge strips 5 is provided with an arc-shaped inclined surface, and the protrusions 601 are provided with two symmetrically distributed strip-shaped inclined surfaces on the side near the axis of the corresponding support tube 4. The arc-shaped inclined surface of the hinge strips 5 and the strip-shaped inclined surface of the protrusions 601 are both used to guide the deformation of the corresponding elastic arc strips 10, reduce the sharp edges of the contact parts of the hinge strips 5 and the protrusions 601 with the elastic arc strips 10, so that the elastic arc strips 10 can squeeze the hinge strips 5 and the protrusions 601.

[0029] Adjusting the fixture shape process: The lampshade to be painted is placed on two support tubes 4, with the widest part of the lampshade located behind the rear support tube 4. The corresponding parts of the lampshade and the two support tubes 4 gradually narrow from back to front, and the center of gravity of the lampshade is located between the two support tubes 4. After the lampshade is placed on the two support tubes 4, since the edge of the lampshade is not flat, there are only two points of contact between the lampshade and the two support tubes 4. The position of the lampshade is adjusted so that the narrower end is lower than the wider end, i.e., the lampshade is tilted. The adjusted lampshade, supported by the two support tubes 4, tends to slide towards the narrower end. During the adjustment process, the lampshade presses against the two support tubes 4, causing the support tubes 4 to swing according to the shape of the lampshade's edge. During this swinging motion, the support tubes 4 drive the corresponding hinge strip 5 to swing, and the hinge strip 5 drives the corresponding main slider 3 to slide along the corresponding main slide rail 2 until the lampshade and the two support tubes 4 are in four-point contact.

[0030] The positions of the four limiting rings 6 are adjusted sequentially so that all four limiting rings 6 abut against the flange of the lampshade. Then the lampshade is removed, and the transmission component 8 is rotated by the moving plate 801. The transmission component 8 drives the supporting arc strip 9 and the elastic arc strip 10 to rotate together, so that the elastic arc strip 10 is sequentially embedded into the groove of the corresponding protrusion 601 and the groove of the corresponding hinge strip 5. In this way, the elastic arc strip 10 simultaneously restricts the axial movement of the protrusion 601 along the support tube 4 and the swing of the hinge strip 5 relative to the support tube 4, thus realizing the operation of changing the fixture.

[0031] Lamp cover painting process: The lamp cover is lifted by a robotic arm and transported above the two support tubes 4 (at this time, the lamp cover is located above and behind the position to be painted, and the projection of the center of gravity of the lamp cover on the horizontal plane is between the projections of the two support tubes 4 on the horizontal plane). The lamp cover is then placed on the two support tubes 4 from top to bottom, with the edge of the lamp cover in contact with the two support tubes 4 and located between two adjacent limiting rings 6 on the same support tube 4. However, since the lamp cover is placed relatively far back from the position to be painted, it cannot contact all four limiting rings 6 at the same time. Under its own weight, the lamp cover slides forward and downward, allowing it to slide along the two support tubes 4. Under the limitation of the four limiting rings 6, the lamp cover finally stops at the position to be painted. At this time, the lamp cover is in contact with all four limiting rings 6 and has a four-point contact with the two support tubes 4. Then, the lamp cover is painted. After the painting is completed, the lamp cover is lifted and transferred to the next process by the robotic arm.

[0032] Example 2

[0033] This embodiment is a further optimization based on Embodiment 1.

[0034] See Figures 4 to 8The limiting ring 6 is threadedly connected to a threaded ring 11, and the limiting ring 6 is slidably connected to an adjusting ring 12. The threaded ring 11 is used to compress the corresponding adjusting ring 12. Two corresponding adjusting rings 12 on the same support tube 4 are located between two threaded rings 11. Three equally spaced annular support bars 121 are provided on the opposing sides of the two corresponding adjusting rings 12 on the same support tube 4. The three support bars 121 are used to ensure that the corresponding adjusting ring 12 is subjected to uniform force in the circumferential direction. In actual use, only the upper elastic bar 13 contacts the lampshade flange. The adjusting ring 12 is made of tough plastic material, such as nylon. Relying on the toughness and flexibility of the adjusting ring 12, the support bars... 121 is capable of bending deformation; each of the limiting rings 6 near the corresponding support strip 121 is equipped with a guide post 122, which is used to support the corresponding support strip 121. An elastic strip 13 is fixed between the support strip 121 and the corresponding limiting ring 6. The elastic strip 13 is an elastic rubber strip, which adapts to the shape of the lampshade flange by its own elastic deformation to provide support for the lampshade. On the other hand, it can ensure the friction when the lampshade contacts the elastic strip 13, which is conducive to maintaining the stability of the lampshade. The minimum distance between two corresponding support strips 121 on the same support tube 4 and different limiting rings 6 is less than the distance between the two limiting rings 6, that is, the support strip 121 protrudes from the corresponding limiting ring 6.

[0035] By rotating the threaded missing ring 11, the threaded missing ring 11 presses against the corresponding adjusting missing ring 12, causing the adjusting missing ring 12 to move relative to the limiting missing ring 6. This causes the support bar 121 to deform under the guidance of the corresponding guide post 122, changing the height of the end of the support bar 121. The support bar 121 then causes the elastic bar 13 to deform, stretching it until the highest end of the support bar 121 can rest on the lampshade and its corresponding flange. At this point, the adjustment is complete. The flange of the lampshade is "pressed" against the upper side of the support tube 4 by the end of the support bar 121, while the flange of the lampshade abuts against the corresponding elastic bar 13.

[0036] The above settings enable the adjustment of the relative position of the adjusting ring 12 and the limiting ring 6 to change the curvature of the end of the support strip 121, thereby changing the length of the elastic strip 13. This allows for full adaptation to the position and thickness of the lampshade flange, while reducing obstruction of the lampshade and ensuring the coating effect. By setting the support strip 121 to protrude from the limiting ring 6, the contact area with the edge of the lampshade is reduced, adapting to situations where the edge of the lampshade is not parallel to the end face of the limiting ring 6. This ensures the lampshade is limited while reducing the impact on the final movement state of the lampshade, which is beneficial for maintaining the uniformity of the final coating position of lampshades of uniform specifications.

[0037] Example 3

[0038] This embodiment is a further optimization based on embodiment 2.

[0039] See Figure 1 , Figure 2 and Figure 9 The mounting frame 1 is fixedly connected to two symmetrically distributed secondary slide rails 14. The secondary slide rails 14 are slidably connected to two secondary sliders 15. The two secondary sliders 15 are respectively fixedly connected to the corresponding main slide rails 2. By relying on the relative sliding of the secondary sliders 15 and the secondary slide rails 14, the distance between the two support tubes 4 can be adjusted, thus improving the adaptability to lampshade specifications.

[0040] See Figure 9 and Figure 10 The mounting frame 1 is fixedly connected to a positioning frame 16, and the main slide rail 2 on the rear side is fixedly connected to an L-shaped frame 17. A mounting plate 18 is provided between the L-shaped frame 17 and the positioning frame 16. The positioning frame 16 and the L-shaped frame 17 are respectively hinged to the mounting plate 18 by two parallel connecting strips 19. By changing the position of the mounting plate 18, the position of the main slide rail 2 on the rear side can be changed synchronously by the transmission of the connecting strips 19. The positioning frame 16 is fixedly connected to a limit frame 20. The limit frame 20 is used to limit the left and right extreme positions of the mounting plate 18. The limit frame 20 is made of ferromagnetic material. A magnet 21 is embedded in the upper part of the mounting plate 18. Since the mounting plate 18 isolates the magnet 21 from the limit frame 20, the magnetic attraction between the magnet 21 and the position where the robotic arm lifts the lampshade is greater than the magnetic attraction between the magnet 21 and the limit frame 20.

[0041] The above setup enables the robotic arm to transfer the lampshade, reducing the distance between the two support tubes 4 after the lampshade is placed on them. This actively changes the position of the lampshade, improving the reliability of the lampshade position adjustment compared to the method of sliding the lampshade by its own weight. At the same time, it can clamp and fix the lampshade flange after the lampshade is placed on the two support tubes 4, improving the stability of the lampshade.

[0042] The lampshade painting process: The robotic arm lifts the lampshade from the left side and moves it above the two support tubes 4. Then, the robotic arm moves the lampshade downwards, placing it on the two support tubes 4 (at this point, the widest part of the lampshade is between the two support tubes 4, and during fixture changes, the mounting plate 18 is kept at its left limit position, eliminating the need to adjust the lampshade to a tilted state). As the robotic arm continues to move downwards, it gradually approaches the magnet 21, increasing the magnetic attraction between them. When the robotic arm contacts the magnet 21, it retracts (i.e., moves to the left). The robotic arm uses magnetic attraction to move magnet 21 and mounting plate 18 to the left together. During the leftward movement of mounting plate 18, it is affected by the two front connecting strips 19 and moves forward. Mounting plate 18 drives the rear main slide rail 2 to move forward through the two rear connecting strips 19. The main slide rail 2 drives the corresponding support tube 4 to move together through the hinge strip 5, so that the distance between the two support tubes 4 is reduced. The support tube 4 drives the two limiting rings 6 on it to move together. The elastic strips 13 on the four limiting rings 6 squeeze the lamp cover, causing the lamp cover to move, thereby adjusting the position of the lamp cover.

[0043] After the mounting plate 18 moves to the left limit position, the mounting plate 18 stops moving. After the robotic arm loses contact with the magnet 21, the mounting plate 18 remains stationary under the magnetic attraction between the magnet 21 and the limiting frame 20. At this time, all four limiting rings 6 are in contact with the lampshade flange, thus limiting the lampshade. Since the elastic strip 13 is in an inclined position when it contacts the lampshade flange, it locks the lampshade flange, which can restrict the vertical movement of the lampshade. Then the lampshade is sprayed. After the spraying is completed, the above steps are repeated in reverse. The robotic arm first moves to the right and then lifts up, so that the mounting plate 18 and the rear main slide rail 2 are reset. At this time, the four elastic strips 13 no longer limit the lampshade. The robotic arm transports the lampshade to the next process for processing.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
