[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Figure 1 FIG. 1 is a schematic diagram of a structure of an automatic assembly device for a car taillight trim strip according to an embodiment of the present invention. Figure 1 As shown, the automatic assembly device includes: a pre-installation station 100, a rolling station 200 and a clamping assembly corresponding to the pre-installation station and the rolling station, a positioning assembly 10, a pre-installation assembly 20, and a rolling assembly 30, wherein:

[0031] The clamping assembly includes an upper mold and a lower mold, the upper mold can move up and down in the vertical direction, and the lower mold can move in the horizontal direction; the positioning assembly 10 is arranged on the lower mold of the pre-installation station 100, and the positioning assembly 10 is used to fix the automobile taillight; the pre-installation assembly 20 is arranged on the upper mold of the pre-installation station 100, and the pre-installation assembly 20 is used to fix the decorative strip in the cavity in the positioning assembly 10, and then pre-install the decorative strip into the lampshade of the automobile taillight along the assembly angle; at least a part of the rolling assembly 30 is movably arranged on the upper mold of the rolling station 200 along the vertical direction and the horizontal direction, and the rolling assembly 30 is used to press the decorative strip into the automobile taillight.

[0032] According to one embodiment of the present invention, the decorative strip includes 3M glue.

[0033] Specifically, Figure 1 As shown, the automatic assembly device of the present invention adopts a double-station one-out-of-two production method. The functional area of ​​the equipment is divided into a pre-installation station 100 and a rolling station 200. The entire device can be set on a workbench. The workbench can be a frame structure. The workbench can be used as an operating base frame to fix the entire device. The upper mold can move up and down in the vertical direction, and the lower mold can move from the pre-installation station 100 to the rolling station 200. The function of the pre-installation station 100 is to replace manual pre-installation of the decorative strips with pneumatic components, in order to ensure the uniqueness and consistency of the pre-installation position of the decorative strips; the function of the rolling station 200 is to complete the rolling operation of the decorative strips by the rolling assembly 30, in order to ensure that the surface area of ​​the decorative strips is subjected to uniform force and the glue inside the 3M glue is squeezed out, so that the decorative strips are more firmly attached. Therefore, the device provides a sustainable and stable double-station operation method for pre-installing and rolling decorative strips, which can realize automatic assembly of decorative strips with high precision, high consistency and firm bonding.

[0034] According to one embodiment of the present invention, Figure 2 and 3 As shown, the positioning assembly 10 includes: a support limit block 11 and a clamping structure 12. The support limit block 11 has an outer shape imitating the shape of a car tail light. The support limit block 11 uses the stress-bearing part of the shell 40 of the car tail light as a support force point, and the support limit block 11 uses the outer contour of the lampshade 50 of the car tail light as a limit; the clamping structure 12 is used to make the support limit block 11 clamp the car tail light.

[0035] Specifically, Figure 2 As shown, the support limit block 11 selects the stress-bearing part of the housing 40 as the support stress point, and then selects the outer contour of the lampshade 50 as the limit, which can ensure that the relative position between the decorative strip and the lampshade remains constant after pre-installation. The influence of welding deviation needs to be eliminated, so it is necessary to select the stress-bearing part of the housing as the support stress point, and then select the outer contour of the lampshade as the limit. Figure 3 As shown, the clamping structure 12 plays a role in fixing and clamping the automobile taillights, including three pressure points O, which can be clamped by an angle cylinder and fixed by a pressure block. The pressure block can be made of POM (Polyoxymethylene, polyoxymethylene resin) material to prevent defects such as crushing and scratching of the automobile taillights.

[0036] It is understandable that Figure 4 As shown, the design of the positioning assembly 10 needs to analyze whether the pre-installed angle of the decorative strip 60 meets the requirements of the product drawing, and adjust the rolling climbing process angle to meet the process requirement of ≤45°.

[0037] According to one embodiment of the present invention, Figure 5-6 and Fig.12As shown, the pre-installed component 20 specifically includes: a positioning plate 21, a precision slide cylinder 22, a vacuum suction cup 23, and a floating limit block, wherein one end of the positioning plate 21 is arranged below the upper mold of the pre-installed station 100; the precision slide cylinder 22 is arranged on the positioning plate 21 at a preset angle, and the precision slide cylinder 22 can perform regular extension and retraction reciprocating motion at a preset angle; the vacuum suction cup 23 is built into the cavity, and is used to absorb the decorative strip 60 in the cavity through vacuum pressure; the floating limit block includes a spring 251, a limit block 252 and a micro linear slide 253, one end of the limit block 252 is connected to the precision slide cylinder 22 through the spring 251 and the micro linear slide 253, and the other end of the limit block 252 has a contour of the decorative strip and a built-in vacuum suction cup.

[0038] Specifically, Figure 7 As shown, since the decorative strip 60 is embedded in the lampshade 50, the small space causes the effective edge height of the limit block 252 to be unable to reach a suitable height, thereby causing the position uniqueness of the decorative strip in the limit block to be unable to be guaranteed. To solve this problem, the present invention designs a floating limit block. Before placing the decorative strip 60, the spring 251 bounces the limit block 252. Since the limit block 252 of the decorative strip 60 is much higher than the edge of the decorative strip 60, it can fully limit the decorative strip 60. During the pre-installation process, the limit block 252 starts to compress the spring 251 after contacting the lampshade 50, and the position of the limit block 252 moves downward, which can ensure the uniqueness of the placement position of the decorative strip and will not cause scratches and other defects to the taillights of the car.

[0039] According to one embodiment of the present invention, Figure 8-9 As shown, the rolling assembly 30 may include: a rodless cylinder 31, a linear guide rail 32, two side fixing plates 33, a bearing follower 34, two side connecting plates 35, a track guide groove 36, and a rolling component, wherein:

[0040] The rodless cylinder 31 is arranged below the upper die of the rolling station; the linear slide 32 is arranged below the upper die of the rolling station, and the linear slide 32 is installed parallel to the rodless cylinder 31 in the horizontal direction; the fixed plates 33 on both sides are L-shaped workpieces, one side of the fixed plate on one side is fixed to the slider of the rodless cylinder 31, and one side of the fixed plate on the other side is fixed to the slider of the linear slide 32; the bearing followers 34 are respectively clamped on the fixed plates 33 on both sides; the connecting plates 35 on both sides connect the fixed plates 33 on both sides into a whole; the track guide groove 36 is arranged below the upper die of the rolling station, and the track guide groove 36 includes two track guide grooves, one track guide groove is installed on one side of the rodless cylinder 31, and the other track guide groove 36 is installed on one side of the linear slide 32; the rolling component is arranged in the middle of the track guide groove 36, and the rolling component can be movably arranged between the track guide grooves in the vertical direction and the horizontal direction.

[0041] Further, according to one embodiment of the present invention, Figure 8-9As shown, the rolling component may include: a rolling connecting plate 371, a compression spring 372, a latch 373, a connecting rod 374, a roller support 375 and a roller 376, wherein:

[0042] The rolling connecting plate 371 is arranged in the track guide groove through the bearing follower 34, and the two side surfaces are fixed to the fixed plates 33 on both sides through the bearing followers 34; the compression spring 372 is arranged in the hole of the rolling connecting plate 371, and the pin 373 can fix the round part to rotate; the connecting rod 374 is arranged in the inner hole of the rolling connecting plate 371, located below the compression spring 372 and fixed to the fixed plates 33 on both sides through the pin 373; the roller support 375 is arranged below the connecting rod 374 and fixed to the connecting rod 374 by screw connection; the roller 376 is arranged on the roller support 375 and the center of the roller 376 is inserted into the pin 373 and fixed to the roller support 375, the roller 376 can drive the compression spring 372 to be compressed through the connecting rod 374, and the rebound force of the compression spring 372 can make the roller 376 always press the decorative strip.

[0043] Specifically, if Figure 10-11 As shown, the working principle of the rolling assembly 30 is that the roller 376 rolls back and forth along the outer contour of the decorative strip to squeeze out the glue inside the 3M tape of the decorative strip, thereby making the 3M adhesive more firmly adhered. The rolling pressure can be continuously maintained at 70N by controlling the compression amount of the compression spring.

[0044] As can be seen from the above, the assembly device of the present invention is a dual-station operation method that can pre-install and roll the decorative strips in a sustainable and stable manner, which can effectively improve the consistency of the decorative strip assembly position and the bonding strength of the 3M glue. The present invention solves the problem of how to precisely position the embedded decorative strips through a floating positioning structure, which plays a vital role in ensuring the uniqueness of the decorative strip assembly position; the present invention uses the principle of a connecting rod mechanism to design a rolling device that reciprocates along a specific trajectory, which can keep the pressure (70N) of each area on the surface of the decorative strip uniform and consistent. The device reciprocates along the trajectory to squeeze out the glue filled inside the 3M, making the decorative strip more firmly adhered.

[0045] The present invention completely solves the quality problems of poor assembly position consistency and warping of decorative strips, and relevant practice proves that the assembly qualification rate of decorative strips assembled by the present invention can reach 100%, so that the assembly quality of decorative strips is qualitatively improved.

[0046] It can be understood that during the operation, the decorative strip is first placed in the pre-installed cavity of the upper mold, the cavity can absorb the decorative strip through the suction cup, and then the car taillight is placed in the lower mold of the pre-installation station 100. After pressing the start buttons on both sides of the automatic assembly device with both hands, the equipment will first complete the pre-installation and rolling of the decorative strip. The entire process rhythm can be controlled within 45S.

[0047] In summary, the automatic assembly device for automobile taillight decorative strips according to the embodiment of the present invention provides a dual-station operation method for pre-assembling and rolling decorative strips in a sustainable and stable manner, which can realize automatic assembly of decorative strips with high precision, high consistency and firm bonding.
