Among them, the decorative part base and the light homogenizing cover plate are combined to form the decorative part body, and the two can be connected and formed by means of two-color injection or laser welding, while the flexible light-emitting sheet, the mounting bottom plate, and the circuit control board need to be installed into the decorative part body by manual assembly.

[0004] Regarding the above related technologies, the inventor believes that it is necessary to provide an assembly device for automotive pixel light-emitting decorative parts for installing the flexible light-emitting sheet and the mounting bottom plate onto the decorative part base, so as to improve the assembly efficiency of automotive pixel light-emitting decorative parts. Summary of the Invention

[0005] In order to improve the assembly efficiency of the flexible light-emitting sheet, the mounting bottom plate and the decorative part body, this application provides an assembly device for automotive pixel light-emitting decorative parts.

[0006] An automotive pixel light-emitting trim assembly device provided by the present application adopts the following technical solution: An automotive pixel light-emitting trim assembly device includes a rotating table, an assembly mold base arranged on the top surface of the rotating table, a first assembly machine for installing the trim body onto the assembly mold base, a second assembly machine for assembling the flexible light-emitting sheet into the corresponding trim body, a third assembly machine for assembling the mounting base plate into the corresponding trim body, a welding machine for thermally welding and fixing the trim body and the mounting base plate, and a blanking device for removing the assembled workpiece from the assembly mold base; the first assembly machine, the second assembly machine, the third assembly machine, the welding machine, and the blanking device are arranged at intervals along the rotation direction of the rotating table; the rotating table is provided with a first through hole that penetrates the upper and lower surfaces and is used for the trim body to pass through; the assembly mold base includes an assembly bottom frame installed on the top surface of the rotating table and facing the first through hole, a clamping seat symmetrically and slidably installed on the assembly bottom frame and used for clamping the trim body, and a clamping cylinder installed on the assembly bottom frame and used for driving the clamping seat to slide; the clamping seat has a clamping groove for arranging the end of the trim body; the first assembly machine includes a first material table for arranging the trim body and a first loading mechanism for transporting the trim body facing the first through hole to the assembly mold base; the first material table includes a first frame, a first material plate installed on the first frame, and a first feeding mechanism capable of aligning the trim bodies on the first material plate with the first through hole one by one; the first loading mechanism includes a first suction cup assembly for sucking the outer side of the trim body, a first lifting cylinder for driving the first suction cup assembly to lift, and a first rotating cylinder for driving the suction cup assembly to rotate; after being driven by the first rotating cylinder, the first suction cup assembly has a state facing the first through hole and a state facing the first loading table.

[0007] By adopting the above technical solution, after being driven by the rotating table, the assembly mold base will sequentially pass through the first assembly machine, the second assembly machine, the third assembly machine, the welding machine, and the blanking device. First, the assembly mold base rotates to the position of the first assembly machine, and the first assembly machine places the trim body in an inverted state on the assembly mold base; then, the assembly mold base rotates to the position of the second assembly machine, and the second assembly machine places the flexible light-emitting sheet into the trim body; then, the assembly mold base rotates to the position of the third assembly machine, and the third assembly machine places the mounting base plate into the trim body; then, the assembly mold base rotates to the position of the welding machine, and the welding machine thermally welds and fixes the mounting base plate in the trim body and presses the flexible light-emitting sheet; finally, the assembly mold base rotates to the position of the blanking device, and the blanking device removes the assembled workpiece from the assembly mold base. The above automotive pixel light-emitting trim assembly device can complete the automatic assembly of the trim body, the flexible light-emitting sheet, and the mounting base plate, which helps to improve the assembly efficiency of automotive pixel light-emitting trims.

[0008] Among them, since the bottom surface of the inner cavity of the decorative part body is provided with arrangement holes for arranging the lamp beads of the flexible light-emitting sheet, it is not possible to directly suck the bottom surface of the inner cavity of the decorative part body with a suction cup. Therefore, the decorative part body is placed upright on the first material table. At this time, the outer side surface of the decorative part body is upward, and the first suction cup assembly sucks on the outer side surface of the decorative part body. Then, the first lifting cylinder retracts to lift the decorative part body, and then the first rotating cylinder drives the decorative part body to rotate so that the decorative part body is in an inverted state. After that, the first lifting cylinder lifts the decorative part body in the inverted state to the assembly mold base, and the clamping seat of the assembly mold base clamps the decorative part body, that is, the feeding of the decorative part body is completed, and the first feeding mechanism resets.

[0009] Among them, the first feeding mechanism on the first material table can complete the feeding of the decorative part bodies one by one, which helps the operator to place multiple decorative part bodies on the first material table at one time to reduce the feeding frequency of the decorative part bodies.

[0010] Optionally, the first frame is provided with a lifting plate for stacking the first material plates and a lifting assembly for driving the lifting plate to lift and lower; first sliding grooves are opened on both sides of the first material plate; the first frame is further provided with a telescopic slide rail that cooperates with the first sliding groove and a telescopic cylinder for driving the telescopic slide rail to expand and contract.

[0011] By adopting the above technical solution, the arrangement of the lifting assembly and the lifting plate can lift the first material plate, so that the first sliding grooves on both sides of the uppermost first material plate are aligned with the telescopic slide rail. After the telescopic slide rail is driven by the telescopic cylinder, it is clamped into the first sliding groove of the first material plate. Driven by the first feeding assembly, the first material plate can feed normally. When the uppermost first material plate finishes feeding, the first feeding assembly will slide the first material plate that has been fed, and the new uppermost first material plate will repeat the previous action for feeding. The arrangement of the above structure enables the staff to arrange multiple first material plates on the first feeding table at one time to reduce the feeding frequency of the decorative part bodies.

[0012] Optionally, the top surface of the lifting plate is provided with a first arrangement groove for placing the first material plate; first positioning columns are arranged at the four corners of the top surface of the first material plate, and first positioning grooves for cooperating with the first positioning columns are arranged at the four corners of the bottom surface of the first material plate.

[0013] By adopting the above technical solution, when arranging the first material plate on the lifting plate, first place the first material plate in the first arrangement groove, and then stack the first material plates through the cooperation of the first positioning columns and the first positioning grooves, which helps to position the first material plate on the first frame to assist the cooperation between the first material plate and the first feeding mechanism, and reduces the probability of the first material plates tipping over after being stacked.

[0014] Optionally, the first feeding mechanism includes a first feeding frame slidably mounted on the top of the first rack and a first feeding assembly for driving the first feeding frame to slide; after being driven by the lifting plate, the first material plate can be arranged in the first feeding frame.

[0015] By adopting the above technical solution, the structure of the first feeding mechanism is specifically disclosed. The first feeding frame can be arranged outside the first material plate at the top and frame the first material plate, so as to be able to drive the first material plate to move synchronously, thereby realizing that the decorative part bodies on the first material plate can be aligned with the first through holes one by one; and when the first material plate finishes feeding, the first feeding frame can make the first material plate disengage from the telescopic slide rail, so that the uppermost first material plate can be normally unloaded.

[0016] Optionally, a carrier for receiving the first material plate after the feeding is completed is arranged on one side of the first rack along the feeding direction of the first material plate.

[0017] By adopting the above technical solution, the first material plate after the feeding is completed can fall onto the carrier, which helps to facilitate the collection of the first material plate by the operator.

[0018] Optionally, a second through hole for the flexible light-emitting sheet and the mounting base plate to pass through is arranged on one side of the rotary table along the rotation direction in the die base assembly; the second assembly machine includes a second feeding table for vertically arranging the flexible light-emitting sheet and a second feeding mechanism for transporting the flexible light-emitting sheet into the corresponding decorative part body; the second feeding mechanism includes a second pneumatic clamp for clamping the flexible light-emitting sheet, a second rotating motor for driving the second pneumatic clamp to swing, a horizontal assembly for driving the second pneumatic clamp to slide horizontally, a lifting assembly for driving the second pneumatic clamp to lift, a abutting plate that can be inserted into the decorative part body and for the flexible light-emitting sheet to abut against, and an abutting cylinder for driving the abutting plate to lift.

[0019] By adopting the above technical solution, the steps of the second assembly machine for assembling the flexible light-emitting sheet onto the ornament body are as follows: First, the second pneumatic gripper of the second loading mechanism clamps the flexible light-emitting sheet through the second through hole and moves the flexible light-emitting sheet above the rotating table; Then, the mold base assembly is driven by the rotating table to face the second loading mechanism; Next, the abutting plate is driven by the abutting cylinder to insert into one end of the inner cavity of the ornament body as the positioning plate of the flexible light-emitting sheet, and the bottom end of the flexible light-emitting sheet is driven by the horizontal assembly and the lifting assembly to abut against the abutting plate; Then, the second pneumatic gripper releases, and is driven by the horizontal assembly, the lifting assembly and the second rotating motor to gradually tilt the flexible light-emitting sheet until the flexible light-emitting sheet is arranged in the inner cavity of the ornament body and the lamp beads on the flexible light-emitting sheet can be arranged in the arrangement holes of the ornament body. The setting of the second assembly machine realizes the arrangement of the flexible light-emitting sheet in the ornament body, and compared with the traditional suction cup structure, the damage to the lamp beads in the flexible light-emitting sheet is smaller.

[0020] Optionally, one end of the assembly bottom frame is hinged to the top surface of the rotating table; The rotating table is further provided with an ejecting cylinder for jacking up the other end of the assembly bottom frame.

[0021] By adopting the above technical solution, the ejecting cylinder can jack up the assembly bottom frame, causing the ornament body on the mold base assembly to tilt, reducing the flipping angle of the flexible light-emitting sheet during the installation process onto the ornament body, thereby facilitating the arrangement of the flexible light-emitting sheet into the corresponding specimen body.

[0022] Optionally, the third assembly machine includes a third loading table for stacking the mounting bottom plates and a third loading mechanism for transporting the mounting bottom plates from the third loading table to the ornament body; The third loading mechanism includes a third suction cup assembly for sucking the back surface of the mounting bottom plate and a third lifting assembly for driving the third suction cup assembly to lift and lower.

[0023] By adopting the above technical solution, the composition of the third assembly machine is specifically disclosed. After being driven by the third lifting assembly, the third suction cup assembly can transport the mounting bottom plate on the third loading table above the rotating table through the second through hole; The mold base assembly is driven by the rotating table to face the third suction cup assembly, and the mounting bottom plate can be arranged in the ornament body after being driven by the third lifting assembly.

[0024] Optionally, the welding machine includes a fourth frame, a welding head vertically slidably mounted on the fourth frame, and a fourth lifting mechanism for driving the welding head to lift and lower; The welding head includes a welding seat, an elastic pressing plate arranged at the bottom of the welding seat and used for pressing the mounting bottom plate, a heat welding piece vertically slidably mounted on the welding seat and used for thermally welding and fixing the ornament body and the mounting bottom plate, and a heat welding driving piece mounted on the welding seat and used for driving the heat welding piece to vertically slide.

[0025] By adopting the above technical solution, the die base assembly transfers the ornament body, the flexible light-emitting sheet and the mounting base plate to face the welding machine directly. After being driven by the fourth lifting mechanism, the welding head of the welding machine descends and inserts into the ornament body. Then, the elastic pressing plate presses the mounting base plate and the flexible light-emitting sheet tightly in the ornament body, and the hot welding piece welds and fixes the hot welding tabs in the ornament body to the hot welding through holes in the mounting base plate. After that, the hot welding driving member drives the hot welding piece to rise, so that the hot welding piece is separated from the hot welding area, facilitating the cooling of the hot welding area. After cooling is completed, the fourth lifting mechanism drives the hot welding head to reset.

[0026] Optionally, the blanking device includes a bearing plate for receiving the assembled workpiece, a fifth lifting mechanism for driving the bearing plate to lift, and two single-side conveying platforms symmetrically arranged on both sides of the bearing plate and used for supporting the ends of the assembled workpiece.

[0027] By adopting the above technical solution, the die base assembly is driven by the rotating table to move to the blanking device. The bearing plate on the blanking device is lifted by the fifth lifting mechanism and abuts against the lower surface of the ornament body. The clamping seat in the die base assembly is opened by the clamping cylinder, and the ornament body gradually descends with the bearing plate until both ends of the ornament body respectively abut against the two single-side conveying platforms. The assembled workpiece is synchronously driven by the two single-side conveying platforms, thus completing the blanking step.
