Description

Technical Field

[0001] The present invention relates to the technical field of fixtures for producing vehicle lamps, and in particular to a leak-proof fixture for producing vehicle lamps. Background Art

[0002] Automotive lights primarily consist of a light source (such as an LED / bulb), an optical system (reflector / lens), a lampshade, a housing, and an electronic control module. During the lampshade production process, various functional coatings are applied to both the inside and outside of the lampshade to enhance durability and optimize optical performance.

[0003] During the lampshade spraying process, a specific fixture is used to fix the lampshade to maintain its stability while being sprayed. There are currently two types of fixtures for fixing lampshades: contoured fixtures and universal fixtures. Contour fixtures are designed for a single lampshade specification, but their significant disadvantage is that when the production line switches lampshade specifications, the fixture must be replaced simultaneously and tedious reinstallation and debugging must be performed, resulting in long changeover time and reduced production efficiency. At the same time, a large number of special fixtures must be stocked to cover all product models, which increases manufacturing costs and complicates warehouse management. Universal fixtures use suction cups or clamps to clamp the edges of the lampshade for fixation. However, their inherent defect is that the clamping mechanism will form an obstructed area on the lampshade surface during spraying, which directly leads to missing or uneven coating thickness in the obstructed area, resulting in appearance defects (such as shadows and dividing lines) and damage to optical performance (such as stray light), greatly increasing the risk of rework and scrap. In addition, relying solely on edge fixation can easily increase the risk of damage to the lampshade edge due to improper clamping force. Summary of the Invention

[0004] The present invention provides a leak-proof fixture for vehicle lamp production, so as to overcome the shortcomings of fixtures used for lampshade spraying, such as long changeover time, coating loss resulting in low production efficiency and high scrap risk.

[0005] The technical solution is: a leak-proof fixture for producing car lights, including:

[0006] The mounting frame is detachably mounted with multiple fixing seats, and the fixing seats are threadedly connected to multiple sliding rods. All the sliding rods on the same fixing seat are commonly fixed with a reinforcing plate and slidably connected to the mounting seat. The mounting seat is provided with a sliding hole for the sliding rod to slide, and the mounting seat is provided with a sliding hole. A support is slidably connected in the sliding hole. All the support members are commonly used to support the lampshade. The central axis of the sliding hole on the same mounting seat is not parallel to the central axis of the sliding hole. The fixing seat is provided with a locking component for locking the relative positions of the sliding rod and the support.

[0007] Furthermore, the sliding hole is inclined from top to bottom toward the installation frame, so as to facilitate placement of the lampshade.

[0008] Furthermore, the support member is provided with a step portion at an end away from the adjacent mounting seat, and the step portion is used to support the lampshade.

[0009] Furthermore, the locking assembly includes:

[0010] The adjusting tube has two guide grooves, the extrusion strip slides in the guide groove, and the extrusion strip is used to squeeze the rubber ring, the elliptical rod is located in the adjusting tube, the knob is fixed to the upper end of the elliptical rod and is slidably and rotatably connected to the adjusting tube, the limit block is located in the knob and fixed to the knob, and the upper end of the adjusting tube is provided with two limit grooves, and the limit groove is used to limit the limit block.

[0011] Furthermore, a friction plate is embedded in the lower side of the step portion, and the lower side surface of the friction plate is lower than the lower side surface of the step portion.

[0012] Furthermore, a curved surface is provided on a side of the step portion away from the adjacent mounting seat.

[0013] Furthermore, the support member and the adjustment tube are both in contact with the adjacent rubber rings, and the friction force between the support member and the adjacent rubber rings is smaller than the friction force between the adjustment tube and the adjacent rubber rings.

[0014] Furthermore, the step portion is slidably connected to an L-shaped piece, the upper side of the L-shaped piece is fixed with an elastic sheet, the elastic sheet is fixed with an extrusion frame, the upper side of the extrusion frame contacts the step portion, and the extrusion frame tilts from top to bottom into the installation frame.

[0015] Furthermore, the elastic sheet is located on a side of the adjacent extrusion frame and the adjacent L-shaped member away from the adjacent step portion, and the extrusion frame contacts the adjacent L-shaped member, so that the extrusion frame can swing unidirectionally relative to the adjacent L-shaped member.

[0016] Furthermore, the step portion is fixed with an elastic block, the L-shaped member and the extrusion frame are both in contact with the adjacent elastic block, the extrusion frame is provided with a protrusion hole, and the elastic block protrudes from the adjacent extrusion frame through the adjacent protrusion hole.

[0017] Compared with the prior art, the present invention has the following advantages: the present invention utilizes a support member to support the lower side of the lampshade flange, and can adapt to the support and fixation of lampshades of different specifications by adjusting the position of the support member. In this way, there is no need to replace and reinstall and debug different contour clamps, thereby improving the applicability to lampshades of different specifications. By supporting the lower side of the lampshade flange, the existing clamps are avoided from blocking the inner and outer sides of the lampshade, reducing the probability of spray leakage and ensuring the uniformity of the lampshade spraying. At the same time, the support method avoids the situation where the edge of the lampshade is damaged by improper clamping force.

[0018] By setting the relationship between the friction force experienced by the support member during movement and the friction force experienced by the mounting base during movement, the movement sequence of the support member and the mounting base can be controlled. In this way, the position of the step portion can be adjusted in two directions by squeezing the step portion by the lampshade, reducing the steps for adjusting the step portion position and improving the production efficiency of the car lamp.

[0019] The inclined extrusion frame is used to guide the lampshade flange to squeeze the L-shaped part during the downward movement, and the elastic sheet is bent to store force. The elastic force of the elastic sheet causes the L-shaped part to exert an extrusion force on the lampshade flange, thereby improving the stability of the lampshade during the spraying process.

DETAILED DESCRIPTION

[0033] Other features and advantages of the present invention will be described in the following description, and in part will become apparent from the description, or will be understood by practicing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures pointed out in the description and the drawings.

[0034] Example 1

[0035] This embodiment provides a leak-proof fixture for vehicle lamp production, which reduces the number of steps required to change the specifications of a lampshade and reduces the obstruction of the lampshade by the fixture during the lampshade spraying process.

[0036] See also Figure 1-Figure 4 , a leak-proof fixture for car lamp production, including: a mounting frame 1, (reference Figure 1) Two rectangular grooves distributed up and down are provided around the mounting frame 1. The mounting frame 1 is installed with multiple fixing seats 2 by bolts. The number and distribution of the fixing seats 2 are determined according to the shape of the lampshade to be sprayed. The number of fixing seats 2 here is six. The following description will take the fixing seat 2 on the left front side as an example to make the relative position relationship of each part clearer; the fixing seat 2 is threadedly connected to three sliding rods 3. The central axes of the three sliding rods 3 are parallel to each other and are not located in the same plane. The upper parts of all the sliding rods 3 on the same fixing seat 2 are fixed together with a reinforcing plate 4. The fixing method of the sliding rod 3 and the reinforcing plate 4 here is selected Bolts, all the sliding rods 3 on the same fixing seat 2 are slidably connected to the mounting seat 5, the mounting seat 5 is provided with three sliding holes 301, the sliding rods 3 slide in adjacent sliding holes 301, the mounting seat 5 is provided with sliding holes 601, and the support member 6 is slidably connected in the sliding holes 601. The central axis of the sliding hole 601 on the same mounting seat 5 is not parallel to the central axis of the sliding hole 301, so that the lower right end of the support member 6 (that is, the position where the support member 6 supports the lampshade) can change its position in the left and right and up and down directions; a locking component for locking the relative positions of the sliding rod 3 and the support member 6 is provided on the fixing seat 2.

[0037] The above arrangement can achieve the purpose of supporting the lower side of the lampshade flange by utilizing the support member 6, and can meet the support and fixing requirements of lampshades of different specifications by adjusting the position of the support member 6. In this way, there is no need to replace and install and debug different contour clamps, thereby improving the applicability to lampshades of different specifications. In addition, by supporting the lower side of the lampshade flange, the existing clamps are avoided from blocking the inner and outer sides of the lampshade, reducing the probability of spray leakage and ensuring the uniformity of the lampshade spraying. At the same time, the support method avoids the situation where the edge of the lampshade is damaged by improper clamping force.

[0038] It is important to understand that (refer to Figure 2 ) In order to enhance the sealing of the lamp and facilitate the installation and positioning of the lampshade, a flange is set along the edge of the lampshade. Figure 2 The lampshade flange shown in the figure is only a part of the actual lampshade.

[0039] See also Figure 2 The sliding hole 601 is inclined from top to bottom toward the mounting frame 1. When the lampshade is placed from top to bottom, the inclined support members 6 are used to guide the movement of the lampshade, which facilitates the positioning of the lampshade. At the same time, all the support members 6 jointly support the lower side of the lampshade flange, and the inclined support members 6 can reduce the obstruction of the outer side of the lampshade, making it easier to spray the outer side of the lampshade.

[0040] See also Figure 2 and Figure 10 A step portion 602 is provided at the lower right end of the support member 6, and the step portion 602 is used to position the lampshade and limit the horizontal direction.

[0041] It should be noted that, in this embodiment, the length of the upper side surface of the right portion of the step portion 602 in the left-right direction is equal to the length of the lampshade flange cross section in the left-right direction.

[0042] See also Figure 2 、 Figure 3 and Figure 5-Figure 9 , the locking assembly includes: a rubber ring 7, a positioning seat 8, an adjusting cylinder 9, two extrusion strips 10 symmetrically distributed in the front and back, an elliptical rod 11, a knob 12 and a limit block 13. The rubber ring 7 is arranged in the mounting seat 5, the positioning seat 8 is fixed to the mounting seat 5 and contacts the rubber ring 7, and the positioning seat 8 is used to keep the position of the rubber ring 7 unchanged; the mounting seat 5 is provided with a placement hole 901, the placement hole 901 is connected with the sliding hole 601, the adjusting cylinder 9 slides in the placement hole 901 and is threadedly connected to the fixing seat 2, the rubber ring 7 is located in the placement hole 901, the adjusting cylinder 9 and the three sliding rods 3 on the fixing seat 2 are distributed in a rectangular shape, the central axis of the adjusting cylinder 9 is parallel to the central axis of the sliding rod 3, the adjusting cylinder 9 passes through the rubber ring 7 and is coaxial with the rubber ring 7, and two symmetrically distributed slide grooves 101 are provided in the middle of the adjusting cylinder 9, and the extrusion strip 10 slides in the slide groove 101 The elliptical rod 11 is located in the adjusting cylinder 9, the cross-section of the elliptical rod 11 is an ellipse, and the major axis of the above ellipse is always in contact with the inner side surface of the adjusting cylinder 9; initially, the minor axis of the ellipse corresponding to the cross-section of the elliptical rod 11 is located between the two extruded bars 10, the spacing between the two extruded bars 10 is less than the major axis length of the ellipse corresponding to the cross-section of the elliptical rod 11, and the maximum distance between the two extruded bars 10 in the horizontal direction is equal to the outer diameter of the adjusting cylinder 9; the knob 12 is fixedly connected to the upper end of the elliptical rod 11 and is slidingly and rotatably connected to the adjusting cylinder 9, and a friction groove is provided on the outer peripheral side of the knob 12; the limit block 13 is located in the knob 12 and is fixedly connected to the knob 12, and the upper end of the adjusting cylinder 9 is provided with two limit grooves 131, and the central angle corresponding to the projection of the midpoint of the two limit grooves 131 on the upper end surface of the adjusting cylinder 9 is 90°, and the limit groove 131 is used to limit the limit block 13.

[0043] The above arrangement can achieve, through the rotation of the elliptical rod 11, the two extrusion strips 10 simultaneously squeeze the rubber ring 7, so that the rubber ring 7 is in contact with the support member 6 and the positioning seat 8 at the same time, and then the relative positions of the slide rod 3, the mounting seat 5 and the support member 6 are locked at the same time, thereby improving the convenience of adjusting the position of the step portion 602.

[0044] The process of locking the position of the step portion 602 after adopting the above setting is as follows: the staff rotates the knob 12 90 degrees. When rotating the knob 12, the staff first lifts the knob 12 upward to a depth of the limit groove 131, so that the limit block 13 is disengaged from one of the limit grooves 131. Then the staff rotates the knob 12 90 degrees, and the knob 12 drives the elliptical rod 11 and the limit block 13 to rotate together. As the elliptical rod 11 rotates, the elliptical rod 11 contacts the two adjacent extrusion bars 10 and squeezes them at the same time. The two extrusion strips 10 are caused to move in opposite directions, and the extrusion strips 10 extend out of the adjacent slide grooves 101 and contact the adjacent rubber rings 7, and squeeze the rubber rings 7 to deform. The extrusion strips 10 on one side squeeze the rubber ring 7 toward the adjacent positioning seat 8, and the extrusion strips 10 on the other side squeeze the rubber ring 7 toward the adjacent support member 6, so that the friction between the support member 6 and the positioning seat 8 and the adjacent extrusion strips 10 increases together, and thus the relative positions of the slide bar 3, the mounting seat 5 and the support member 6 are locked by friction.

[0045] After the knob 12 is rotated 90°, the limit block 13 corresponds to another limit groove 131. At this time, the staff presses the knob 12 downward, so that the knob 12 drives the limit block 13 to insert into the limit groove 131, and limits the limit block 13. In this way, the position of the knob 12 is locked to prevent the knob 12 from rotating accidentally during the production process.

[0046] The process of spraying the lampshade after adopting the above-mentioned setting: in the lampshade spraying process, the staff moves the lampshade to the top of the mounting frame 1 in the state to be sprayed, and moves the lampshade downward so that the flange of the lampshade is placed on the six steps 602. During this process, the inclined support member 6 can guide the lampshade so that the lampshade is finally moved to the step portion 602, and then the inner and outer sides of the lampshade are sprayed respectively.

[0047] The process for replacing the specifications of the lampshade after adopting the above-mentioned setting is as follows: repeat the above-mentioned process of locking the position of the step portion 602 in reverse to reduce the friction between the support member 6 and the positioning seat 8 and the adjacent extrusion strip 10. At this time, the staff adjusts the positions of the six step portions 602 in turn according to the specifications of the new lampshade, that is, the staff controls the support member 6 to slide in the upper left and lower right directions and the up and down directions in turn to change the position of the step portion 602. After the adjustment is completed, the staff re-locks the position of the step portion 602.

[0048] Example 2

[0049] This embodiment provides a leak-proof fixture for producing vehicle lamps, which provides a function for conveniently adjusting the position of the step portion 602 based on the first embodiment.

[0050] See also Figure 10 and Figure 11A friction plate 14 is embedded in the lower side of the step portion 602 , and the lower side of the friction plate 14 is lower than the lower side of the step portion 602 . The friction plate 14 is made of silicone material, so that there is good friction between the friction plate 14 and the lampshade.

[0051] It should be noted that, in this embodiment, the length of the upper side surface of the right portion of the step portion 602 in the left-right direction is equal to the length of the lampshade flange cross section in the left-right direction.

[0052] See also Figure 10 A curved surface 603 is provided on the side of the step portion 602 away from the adjacent mounting seat 5. The curved surface 603 is used to contact the outer side of the lampshade when adjusting the position of the step portion 602 and reduce the probability of the lampshade being scratched when squeezing the curved surface 603 and moving.

[0053] See also Figure 6 The support member 6 and the adjusting tube 9 are both in contact with the adjacent rubber ring 7, and the friction force between the support member 6 and the adjacent rubber ring 7 is smaller than the friction force between the adjusting tube 9 and the adjacent rubber ring 7, and the elastic force of the friction plate 14 is smaller than the friction force between the adjusting tube 9 and the adjacent rubber ring 7.

[0054] The above setting can be achieved by setting the relationship between the friction force experienced by the support member 6 during the movement and the friction force experienced by the mounting seat 5 during the movement, so as to realize the control of the movement sequence of the support member 6 and the mounting seat 5. In this way, the position of the step portion 602 can be adjusted in the upper left and lower right and up and down directions by squeezing the step portion 602 by the lampshade, thereby reducing the steps of adjusting the position of the step portion 602 and improving the production efficiency of the car lights.

[0055] After adopting the above-mentioned setting, the process of adjusting the position of the step portion 602 is as follows: the staff first unlocks the position of the step portion 602, and then moves the lampshade to be sprayed in the direction of spraying (the lampshade is in an upward convex state at this time) to the bottom of the mounting frame 1, and starts to move upward. The outer side surface of the lampshade contacts the six curved surfaces 603 in turn. After the lampshade contacts the curved surfaces 603, as the lampshade moves upward, relative sliding occurs between the curved surfaces 603 and the outer side surfaces of the lampshade. During the relative sliding process, the lampshade squeezes the support member 6 through the curved surface 603 to move, so that the support member 6 moves relative to the adjacent mounting seat 5. At the same time, the distance between the lampshade flange and the curved surface 603 gradually decreases, and finally the flange of the lampshade contacts the lower side surfaces of the six friction plates 14 in turn.

[0056] After the lampshade flange contacts the first friction plate 14, as the lampshade moves upward, the lampshade squeezes the friction plate 14 and deforms it, causing the lampshade flange to contact the lower side of the step portion 602. At this time, the lampshade stops moving relative to the step portion 602, and then the lampshade drives the support member 6 and the mounting seat 5 to move upward. The mounting seat 5 moves upward along the adjacent slide bar 3. At the same time, the distance between the lampshade flange and the remaining five friction plates 14 gradually decreases. After all six friction plates 14 are in contact with the lampshade flange, the staff continues to move the lampshade upward by a distance of the friction plate 14 itself, so that the six friction plates 14 are in contact with the lampshade flange. The wipes 14 are all in a compressed state, and the lampshade flange contacts the lower side surfaces of the six step portions 602, and the lampshade is stopped from moving (because the length of the upper side surface of the right part of the step portion 602 in the left and right directions is equal to the length of the lampshade flange cross-section in the left and right directions, the lampshade flange can be just stuck between the six step portions 602), and the knob 12 is turned in turn to lock the position of the step portion 602; the adjustment of the position of the step portion 602 is completed in this way, and the staff does not need to adjust the position of the six step portions 602 in turn, thereby improving work efficiency.

[0057] Example 3

[0058] This embodiment provides a leak-proof fixture for producing vehicle lamps, which provides a function of enhancing the stability of the lampshade based on the second embodiment.

[0059] See also Figure 10-12 The step portion 602 is connected to an L-shaped part 15 for sliding left and right. The L-shaped part 15 is made of hard metal. An elastic piece 16 is fixed to the upper side of the L-shaped part 15. The elastic piece 16 is made of elastic metal. Initially, the elastic piece 16 is in a free and unstressed state. The elastic piece 16 is fixed to an extrusion frame 17. The upper side of the extrusion frame 17 contacts the step portion 602, and the lower side of the extrusion frame 17 contacts the upper side of the L-shaped part 15. The extrusion frame 17 tilts from top to bottom toward the inside of the mounting frame 1.

[0060] The above setting can be achieved by using the inclined extrusion frame 17 to guide the lampshade flange to squeeze the L-shaped part 15 during the downward movement, and to make the elastic sheet 16 bend and store force. Relying on the elastic force of the elastic sheet 16, the L-shaped part 15 exerts an extrusion pressure on the lampshade flange, thereby improving the stability of the lampshade during the spraying process.

[0061] It should be noted that in this embodiment, the length of the upper side surface of the right part of the step portion 602 in the left-right direction is greater than the length of the lampshade flange section in the left-right direction, and the shortest distance between the L-shaped part 15 and the right side surface of the step portion 602 is less than the length of the lampshade flange section in the left-right direction.

[0062] See also Figure 12The elastic piece 16 is located on the side of the adjacent extrusion frame 17 and the adjacent L-shaped member 15 away from the adjacent step portion 602, and the lower side of the extrusion frame 17 contacts the upper side of the adjacent L-shaped member 15, so that the extrusion frame 17 can rotate clockwise relative to the adjacent L-shaped member 15 (in this embodiment, the attached Figure 10 The front view is a rotational perspective) and the one-way swing facilitates the lampshade flange to squeeze the extrusion frame 17 and the L-shaped member 15 to move.

[0063] When the lampshade is placed on the step portion 602, the staff will take the fixing seat 2 at the left front of the mounting frame 1 as an example to explain: when the staff places the lampshade on the step portion 602, the lampshade flange slides along the extrusion frame 17 and squeezes the extrusion frame 17 to the left. The upper side of the extrusion frame 17 slides upward along the right side of the step portion 602, and at the same time, the lower side of the extrusion frame 17 moves to the left, causing the extrusion frame 17 to rotate clockwise. The extrusion frame 17 drives the L-shaped member 15 to move left through the elastic sheet 16. At the same time, the elastic sheet 16 bends and accumulates force until the lampshade flange contacts the right side of the L-shaped member 15. The extrusion frame 17, the elastic sheet 16 and the L-shaped member 15 stop moving. After the lower side of the lampshade flange contacts the step portion 602, the positioning and fixing of the lampshade is completed; relying on the elasticity of the elastic sheet 16, the L-shaped member 15 always has a tendency to move right, and then the L-shaped member 15 provides a rightward extrusion force on the lampshade flange, thereby enhancing the stability of the lampshade during the production process.

[0064] Example 4

[0065] This embodiment provides a leak-proof fixture for producing vehicle lamps, which is further optimized based on the third embodiment.

[0066] See also Figure 10-12 The step portion 602 is fixed with an elastic block 18, which is made of silicone material, and the surface of the elastic block 18 has been surface-modified to reduce the friction between the elastic block 18 and the lampshade, so that the contact between the elastic block 18 and the lampshade flange does not affect the normal downward movement of the lampshade; the L-shaped member 15 and the extrusion frame 17 are in contact with the adjacent elastic block 18, and the extrusion frame 17 is provided with a protrusion hole 181, and the elastic block 18 protrudes from the adjacent extrusion frame 17 through the adjacent protrusion hole 181.

[0067] The above arrangement can achieve the purpose of increasing the squeezing force of the L-shaped part 15 on the lampshade flange by utilizing the elasticity of the elastic block 18, and utilizing the characteristic of the elastic block 18 being deformed by being squeezed, so that the elastic block 18 can protrude from the probing hole 181 and deform to the top of the lampshade flange, thereby limiting the lampshade flange and further enhancing the stability of the lampshade during the production process.

[0068] It should be noted that, in this embodiment, the thickness of the lampshade flange in the vertical direction is greater than the thickness of the L-shaped member 15 in the vertical direction, and the thickness of the lampshade flange in the vertical direction is less than the distance between the probe hole 181 and the adjacent step portion 602 in the vertical direction.

[0069] The process of placing the lampshade after adopting the above arrangement is as follows: the lampshade flange squeezes the squeezing frame 17, causing the squeezing frame 17 to swing and the L-shaped member 15 to move left. During this process, the L-shaped member 15 and the squeezing frame 17 squeeze the elastic block 18 together, causing the elastic block 18 to deform and provide support for the L-shaped member 15 and the squeezing frame 17. At the same time, the deformed portion of the elastic block 18 protrudes from the protruding hole 181. As the lampshade flange squeezes the squeezing frame 17, the portion of the elastic block 18 protruding from the protruding hole 181 aligns with the lampshade flange. As the lampshade flange continues to move downward until the lampshade flange contacts the L-shaped part 15, as the lampshade flange continues to move downward, the elastic block 18 slides along the lampshade flange, and finally when the lampshade flange contacts the step portion 602, the lampshade flange moves to the bottom of the probe hole 181. At this time, the elastic block 18 loses contact with the left side of the lampshade flange and contacts with the upper side of the lampshade flange, limiting the upper side of the lampshade flange, thereby improving the stability of the lampshade during the production process.

[0070] After the lampshade is sprayed, the lampshade is moved upward, and the lampshade flange squeezes the six elastic blocks 18, causing the elastic blocks 18 to deform. At the same time, the lampshade flange slides along the L-shaped piece 15, and finally the lampshade flange loses contact with the L-shaped piece 15. At this time, the L-shaped piece 15 moves to the right under the elastic force of the elastic blocks 18 and the elastic sheet 16, and the extrusion frame 17 rotates counterclockwise under the elastic force of the elastic sheet 16. Finally, the L-shaped piece 15, the elastic sheet 16, the extrusion frame 17 and the elastic blocks 18 are all restored.

[0071] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
