Description

Technical Field

[0001] This utility model relates to the field of lighting assembly device technology, and in particular to an automatic assembly and loading nut device for vehicle lamp housings. Background Technology

[0002] With the rapid development of the times, traditional machinery and industrial manufacturing are accelerating their evolution towards automation, intelligence, and miniaturization. Against the backdrop of continuous technological innovation, there is an urgent need to design new automated devices to better meet customer needs, control project costs, and improve automation levels. In the existing technology of the automotive lighting industry, the mounting nut on the headlight is used to connect the lamp to the sheet metal of the vehicle body. Therefore, most headlight housings are designed with mounting nuts, and the mounting nuts and headlight housings are usually assembled using a snap-fit ​​method.

[0003] The current assembly method involves first placing the housing on the tooling, then placing the mounting nut on a designated limit block next to the tooling. A cylinder then pushes the limit block horizontally, extending and retracting to push the mounting nut onto the housing. However, this existing assembly method has the following technical drawbacks: the cylinder drive mechanism only has horizontal displacement capability. When the mounting nut deviates vertically from the housing slot, the equipment cannot adjust the vertical position of the mounting nut itself, leading to a significantly higher assembly failure rate. Furthermore, the mounting nut is prone to wobbling during movement due to the lack of effective restraint, posing a risk of falling off, and even slight wobbling can reduce assembly accuracy. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to solve the technical problem that the insufficient vertical adjustment capability of the mounting nut in the prior art leads to an increased assembly failure rate and poor motion stability causing the risk of falling off, this utility model provides an automatic mounting nut assembly device for vehicle headlight housing, which ensures that the mounting nut can be adjusted up and down, and improves the stability during transportation.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an automatic assembly and loading nut device for vehicle lamp housing, which includes: a frame;

[0006] A mold clamping assembly, wherein the mold clamping assembly is disposed on the frame;

[0007] An upper mold assembly is disposed on the mold closing assembly. The mold closing assembly is used to drive the upper mold assembly to move along the z-axis direction. The upper mold assembly includes: a first cylinder, a limiting buckle, and a magnetic suction element. The limiting buckle is disposed on the first cylinder. The first cylinder drives the limiting buckle to move along the x-axis direction. The limiting buckle is provided with the magnetic suction element for magnetically attracting a first workpiece.

[0008] The lower mold assembly is located below the upper mold assembly. The lower mold assembly includes a slide rail assembly and a fixture for carrying the second workpiece. The slide rail assembly is mounted on the frame, and the fixture is slidably mounted on the slide rail assembly. The slide rail assembly drives the fixture to move along the y-axis. The specific technical effect is as follows: By setting the mold closing assembly to drive the upper mold assembly to move up and down along the Z-axis, the vertical misalignment error between the loading nut and the housing slot can be directly compensated. Combined with the first cylinder driving the limit buckle to move along the X-axis, and the slide rail assembly driving the fixture to move along the Y-axis, the three form an XYZ three-axis degree-of-freedom adjustment system. By adjusting the spatial position of the loading nut and the housing, the assembly failure rate is reduced. The loading nut is attracted by the magnetic components on the limit buckle, utilizing magnetic properties to achieve stable fixation, effectively preventing shaking and detachment risks during transport.

[0009] Furthermore, the upper mold assembly also includes a first sensor connected to the mold closing assembly. The second workpiece has a slot for accommodating the first workpiece, and the first sensor is used to detect whether the first workpiece is present in the slot.

[0011] Furthermore, the mold clamping assembly also includes a connecting block, a vertical guide rod, an oil-free bushing, and a fixing seat. The oil-free bushing is connected to the upper base plate and is fitted over the vertical guide rod. The connecting block is connected to the upper end of the vertical guide rod, and the lower end of the vertical guide rod is connected to the movable plate via the fixing seat. The specific technical effect is that the cooperative design of the vertical guide rod and the oil-free bushing achieves a vertical guiding function, thereby improving the accuracy of the upper mold assembly's movement.

[0012] Furthermore, a first reinforcing rib is provided on the upper base plate, extending along the length of the upper base plate. The specific technical effect is that the rigidity of the upper base plate is improved by providing the first reinforcing rib, further providing a stable foundation for the high-precision assembly of the mounting nut and the housing.

[0016] Furthermore, the limiting buckle is provided with a contoured slot for placing the first workpiece, and the magnetic suction component is located on one side of the contoured slot.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] like Figures 1 to 4 The diagram shows a preferred embodiment of the present invention. This embodiment's automatic assembly and mounting nut device for vehicle headlight housings includes: a frame 1, two mold-closing components 2, two upper mold components 3, and two lower mold components 4. One mold-closing component 2, one upper mold component 3, and one lower mold component 4 constitute a tooling module. The two tooling modules are arranged side-by-side on the frame 1. It should be noted that for vehicle headlight housings with long, narrow structures or large dimensions, using two tooling modules allows for the assembly of mounting nuts at both ends of the headlight housing, improving production efficiency. If the headlight housing is small, only one tooling module is needed.

[0032] The mold clamping assembly 2 is mounted on the frame 1; the upper mold assembly 3 is mounted on the mold clamping assembly 2, and the mold clamping assembly 2 is used to drive the upper mold assembly 3 to move along the z-axis. The upper mold assembly 3 includes: a first cylinder 301, a limit buckle 302 and a magnetic suction component 303. The limit buckle 302 is mounted on the first cylinder 301, and the first cylinder 301 drives the limit buckle 302 to move along the x-axis. The limit buckle 302 is provided with a magnetic suction component 303 for magnetically attracting the first workpiece 5. The lower mold assembly 4 is located below the upper mold assembly 3. The lower mold assembly 4 includes a slide rail assembly and a tooling 401 for carrying the second workpiece. The slide rail assembly is mounted on the frame 1, and the tooling 401 is slidably mounted on the slide rail assembly. The slide rail assembly drives the tooling 401 to move along the y-axis.

[0033] Specifically, the first workpiece 5 is the loading nut, and the second workpiece is the housing.

[0034] In a preferred embodiment, the upper mold assembly 3 further includes a first sensor 304 connected to the mold closing assembly 2. The second workpiece has a slot for accommodating the first workpiece 5, and the first sensor 304 is used to detect whether the first workpiece 5 is in the slot. Thus, by detecting whether there is a loading nut in the slot using the first sensor 304, omissions are avoided.

[0035] In a preferred embodiment, the frame 1 includes an upper base plate 101, and the mold clamping assembly 2 includes a mold clamping cylinder 201, a movable plate 202, and a floating joint 203. The mold clamping cylinder 201 is disposed on the upper base plate 101, and the moving end of the mold clamping cylinder 201 is connected to the movable plate 202 through the floating joint 203. The mold clamping cylinder 201 drives the movable plate 202 to move along the z-axis direction, and the upper mold assembly 3 is disposed on the movable plate 202.

[0036] In a preferred embodiment, the mold clamping assembly 2 further includes a connecting block 204, a vertical guide rod 205, an oil-free bushing 206, and a fixing seat 207. The oil-free bushing 206 is connected to the upper base plate 101 and is sleeved on the outside of the vertical guide rod 205. The connecting block 204 is connected to the upper end of the vertical guide rod 205, and the lower end of the vertical guide rod 205 is connected to the movable plate 202 via the fixing seat 207. Thus, through the cooperative design of the vertical guide rod 205 and the oil-free bushing 206, a vertical guiding function is achieved, thereby improving the accuracy of the movement of the upper mold assembly 3.

[0037] In a preferred embodiment, a first reinforcing rib 102 is provided on the upper base plate 101, and the first reinforcing rib 102 extends along the length direction of the upper base plate 101. Thus, by providing the first reinforcing rib 102, the rigidity of the upper base plate 101 is improved, further providing a stable foundation for the high-precision assembly of the mounting nut and the housing.

[0038] In a preferred embodiment, the frame 1 further includes a lower base plate 103, and the slide rail assembly includes a lower mold slide rail 402, a slide cylinder 403, and a sliding plate 404. The lower mold slide rail 402 is disposed on the lower base plate 103 along the y-axis direction, the slide cylinder 403 is disposed on the lower base plate 103, the slide cylinder 403 includes a sliding component slidably disposed on the lower mold slide rail 402, the sliding plate 404 is disposed on the sliding component, and the tooling 401 is disposed on the sliding plate 404.

[0039] Specifically, the sliding plate 404 is provided with a second reinforcing rib 410, which improves the strength of the sliding plate 404.

[0040] In a preferred embodiment, a limit stop 405 is provided on the sliding plate 404, and a buffer 406 that cooperates with the limit stop 405 is provided on the lower base plate 103. Thus, the cooperation structure between the buffer 406 and the limit stop 405 serves both as a limit and as a buffer. When the sliding plate 404 reaches its travel end point, the limit stop 405 and the buffer 406 undergo a flexible collision, effectively reducing the impact force of the sliding plate 404 on the frame 1, thereby improving the stability and service life of the equipment.

[0041] In a preferred embodiment, the sliding plate 404 is provided with a limit block 407, a clamping cylinder 408, and a second sensor 409 for detecting whether there is a second workpiece on the fixture 401. The limit block 407 is located at one end of the fixture 401, and the two ends of the fixture 401 are respectively provided with clamping cylinders 408 for clamping the second workpiece. The second sensor 409 is signal-connected to the clamping cylinders 408. Thus, through the linkage control of the limit block 407, the second sensor 409, and the clamping cylinders 408, precise positioning and automated clamping of the housing assembly are achieved.

[0042] In a preferred embodiment, the limiting buckle 302 is provided with a contoured jaw for placing the first workpiece 5, and the magnetic suction element 303 is provided on one side of the contoured jaw. Thus, through the dual action of the contoured jaw and the magnetic suction element 303, the mechanical positioning of the loading nut and the stability during the transfer process are achieved.

[0043] The working process of this utility model is as follows:

[0044] The housing is placed on the fixture 401, and one end of the housing is positioned by the limit block 407. Then the second sensor 409 detects whether there is a housing on the fixture 401. If the second sensor 409 detects the housing, the clamping cylinders 408 at both ends of the fixture 401 are activated to clamp the housing. Then the slide cylinder 403 drives the sliding plate 404 to move along the y-axis to the designated working position.

[0045] Manual or other feeding devices feed the loading nut into the contoured slot on the limit buckle 302. At this time, the magnetic suction component 303 attracts the loading nut, and the mold closing cylinder 201 drives the movable plate 202 to descend along the z-axis, thereby driving the upper mold assembly 3 to approach the housing placed on the tooling 401. At the same time, the first cylinder 301 drives the limit buckle 302 to move along the x-axis to adjust the position of the loading nut in the x-axis direction. After it moves to the top of the slot on the housing, the mold closing cylinder 201 continues to drive the movable plate 202 to descend along the z-axis until the loading nut is locked in the slot.

[0046] Subsequently, the first cylinder 301 drives the limit buckle 302 to move along the x-axis to move away from the slot of the housing. The first sensor 304 is used to detect whether there is a mounting nut in the slot. If the detection result is OK, it means that the lamp assembly is qualified. If the detection result is NG, it means that the lamp assembly is unqualified. The mold closing cylinder 201 drives the movable plate 202 to rise and reset along the z-axis. The slide cylinder 403 drives the sliding plate 404 to move and reset along the y-axis. The clamping cylinder 408 releases the clamp on the housing and removes the housing.

[0047] Compared with the prior art, the beneficial effects of this utility model are:

[0048] (1) This utility model can directly compensate for the vertical misalignment error between the loading nut and the housing slot by setting the mold clamping component 2 to drive the upper mold component 3 to move up and down along the Z axis. In addition, the first cylinder 301 drives the limit buckle 302 to move along the x axis, and the slide rail component drives the tooling 401 to move along the y axis. The three form an XYZ three-axis degree of freedom adjustment system. By adjusting the spatial position of the loading nut and the housing, the assembly failure rate is reduced. The loading nut is attracted by the magnetic suction component 303 on the limit buckle 302, and the magnetic force is used to achieve stable fixation, effectively ensuring the risk of shaking and falling off during the transportation process.

[0049] (2) This utility model uses a first sensor 304 to detect whether there is a loading nut in the slot, thus avoiding missing installation.

[0050] (3) This utility model achieves precise positioning and automated clamping of the housing assembly through the linkage control of the limiting block 407, the second sensor 409 and the clamping cylinder 408. The limiting block 407 positions one end of the housing. When the housing is installed in place, the second sensor 409 is triggered. The second sensor 409 is used to detect whether there is a second workpiece on the tooling 401. If there is a second workpiece, the clamping cylinders 408 at both ends of the tooling 401 are activated to clamp the housing.

[0051] The above description is based on the preferred embodiments of this utility model. Through the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined by the scope of the claims.
