[0030] like Figure 1 As shown, the first embodiment provided by the present application is a turn signal actuator lower cover injection molding device, whose structure includes a material receiving mechanism 1, a PIN needle processing station 2, an injection molding station 3 and a transfer station 4, the material receiving mechanism 1 is used to collect the finished product 100 formed by injection molding of the shell and the PIN needle, the PIN needle processing station is used to process the PIN needle, the injection molding station 3 is used to injection mold the PIN needle and the shell, and the transfer station 4 is used to transfer the PIN needle from the PIN needle processing station 2 to the injection molding station 3 and transfer the finished product 100 from the injection molding station 3 to the material receiving mechanism 1.

[0031] In actual use, the PIN needle is shaped and aligned at the PIN needle processing station 2, and then the PIN needle is transferred to the PIN needle and shell injection molding station 3 for injection molding using the transfer station 4, so that the PIN needle and the injection-molded shell form a finished product 100, and then the finished product 100 is transferred to the material receiving mechanism 1 through the transfer station 4.

[0032] In the above design, the PIN needle and the housing can be quickly injection-molded, which effectively improves work efficiency.

[0033] Specifically: Figure 2 As shown, the PIN needle processing station 2 includes a No. 2 frame 21, a PIN needle feeding mechanism 22, a PIN needle shaping mechanism 23, a PIN needle discharging mechanism 24 and a PIN needle transferring mechanism 25 arranged on the No. 2 frame 21, the PIN needle feeding mechanism 22 is used to transfer the PIN needles to the PIN needle shaping mechanism 23, the PIN needle shaping mechanism 23 is used to shape the PIN needles, the PIN needle discharging mechanism 24 is used to place the shaped PIN needles, and the PIN needle transferring mechanism 25 is used to transfer the PIN needles from the PIN needle shaping mechanism 23 to the PIN needle discharging mechanism 24.

[0034] In actual use, the PIN needle is raised to the PIN needle shaping mechanism 23 by the PIN needle feeding mechanism 22, and then the PIN needle is shaped by the PIN needle shaping mechanism 23, and then the PIN is transferred from the PIN needle shaping mechanism 23 to the PIN needle discharge mechanism 24 by the PIN needle transfer mechanism 25, and then the PIN needle is transferred from the PIN needle discharge mechanism 24 to the injection molding station 3 through the transfer station 4.

[0035] In the above design, the structural design and specific implementation method of the PIN needle processing station 2 can effectively realize the processing of the PIN needle.

[0036] Specifically: Figure 2 As shown, the PIN needle feeding mechanism 22 includes a vibration plate 221 arranged on the No. 2 frame 21, a No. 2 robot arm A222 arranged on the No. 2 frame 21, and a No. 2 adsorption component A223 arranged at the output end of the No. 2 robot arm A222; the PIN needle transfer mechanism 25 includes a No. 2 robot arm B arranged on the No. 2 frame 21 and a No. 2 adsorption component B arranged at the output end of the No. 2 robot arm B.

[0037] In actual use, after the unprocessed PIN is adsorbed by the second adsorption component A223, the second adsorption component A223 is driven by the second mechanical arm A222 to place the PIN in the PIN shaping mechanism 23. The second mechanical arm B drives the second adsorption component B to transfer the PIN in the PIN shaping mechanism 23 to the PIN discharge mechanism 24.

[0038] In the above design, the PIN needle feeding mechanism 22 and the PIN needle transferring mechanism 25 facilitate the rapid transfer of the PIN needles.

[0039] Specifically: Figure 3 As shown, the PIN needle shaping mechanism 23 includes a No. 2 base A232 arranged on the No. 2 frame 21, a No. 2 linear guide A231 arranged horizontally on the No. 2 base A232, a No. 2 fixture A233 slidably arranged on the No. 2 linear guide A231, a No. 2 cylinder A234 arranged on the No. 2 base A232 for driving the No. 2 fixture A233 to slide along the No. 2 linear guide A231, a No. 2 support A235 arranged on the No. 2 base A232, a No. 2 lifting seat 236 slidably arranged on the No. 2 support A235, a punch assembly 237 arranged on the No. 2 lifting seat 236, and a No. 2 oil cylinder 238 arranged on the No. 2 support A235 for driving the No. 2 lifting seat 236 to rise and fall, and the PIN needle feeding mechanism 22 and the PIN needle transfer mechanism 25 are respectively located at both ends of the No. 2 linear guide A231.

[0040] In actual use, after the No. 2 air cylinder A234 drives the No. 2 fixture A233 to move to the material receiving position, the PIN needle feeding mechanism 22 places the PIN needle to be processed in the No. 2 fixture A233, and then the No. 2 air cylinder A234 drives the No. 2 fixture A233 to reset, and then the No. 2 oil cylinder 238 drives the No. 2 lifting seat 236 to move downward, so that the No. 2 lifting seat 236 drives the punch assembly 237 to move downward to realize the shaping of the PIN needle.

[0041] In the above design, the structural design and specific implementation method of the PIN needle shaping mechanism 23 can effectively realize the shaping of the PIN needle.

[0042] Specifically: Figure 3 As shown, the No. 2 lifting seat 236 includes an upper plate 2361 and a lower plate 2362 which are slidably connected to the No. 2 support A235, the punch assembly 237 includes a mounting plate 2371 fixedly set on the upper plate 2361, an elastic assembly A2372 connecting the mounting plate 2371 and the lower plate 2362, a forming punch 2374 and a plurality of positioning pins 2373 arranged on the lower end surface of the mounting plate 2371, and the No. 2 jig A233 is provided with linear bearings corresponding to the positioning pins 2373 one by one.

[0043] In actual use, when the PIN needle needs to be shaped, the upper plate 2361 is driven downward by the No. 2 cylinder 238, driving the mounting plate 2371 to move downward synchronously. Since the mounting plate 2371 drives the elastic component downward during the downward movement, the elastic component A2372 is compressed and drives the lower plate 2362 to move downward synchronously. Finally, the forming punch 2374 passes through the lower plate 2362 to shape the PIN needle, and the positioning pin 2373 cooperates with the linear bearing to achieve positioning.

[0044] In the above design, the structural design and specific implementation method of the No. 2 lifting seat 236 and the punch assembly 237 can effectively realize the rapid shaping of the PIN needle and ensure the accuracy of the shaping.

[0045] Specifically: Figure 4 As shown, the PIN needle discharge mechanism 24 includes a No. 3 linear guide A241 and a No. 3 linear guide B242 arranged in parallel on the No. 2 frame 21, a No. 3 plate A243 slidably arranged on the No. 3 linear guide A241, a slider slidably arranged on the No. 3 linear guide B242, a No. 3 plate B244 fixedly arranged on the slider, a No. 3 cylinder A245 fixedly arranged on the No. 2 frame 21 for driving the No. 3 plate A243 to slide along the No. 3 linear guide A241, and a No. 3 cylinder B246 for driving the No. 3 plate B244 to drive the slider to move along the No. 3 linear guide B242, the No. 3 plate B244 can move to above the No. 3 plate A243, and the No. 3 plate A243 and the No. 3 plate B244 are both provided with a discharge fixture 247 for placing PIN needles.

[0046] In actual use, the material discharge jig 247 on the third plate A243 and the material discharge jig 247 on the third plate B244 receive materials alternately. When the third cylinder A245 drives the third plate A243 to move to the material receiving position, the third cylinder B246 drives the third plate B244 to move to the material discharging position. At this time, the PIN needle transfer mechanism 25 transfers the shaped PIN needles from the PIN needle shaping mechanism 23 to the material discharge jig 247 on the third plate A243, and the transfer station 4 transfers the PIN needles in the material discharge jig 247 on the third plate B244 to the injection molding station 3. When the No. 3 cylinder A245 drives the No. 3 plate A243 to move to the discharge position, the No. 3 cylinder B246 drives the No. 3 plate B244 to move to the receiving position. At this time, the PIN needle transfer mechanism 25 transfers the shaped PIN needle from the PIN needle shaping mechanism 23 to the discharge fixture 247 on the No. 3 plate B244, and the transfer station 4 transfers the PIN needle in the discharge fixture 247 on the No. 3 plate A243 to the injection molding station 3.

[0047] In the above design, the PIN needle discharging mechanism 24 can alternately receive the shaped PIN needles, thereby effectively improving the working efficiency.

[0048] Specifically: Figure 6 As shown, the injection molding station 3 includes a third frame 31, a turntable 32 rotatably arranged on the third frame 31, a driving assembly arranged on the third frame 31 for driving the turntable 32 to rotate, two lower molds 34 arranged on the turntable 32 symmetrically along the rotation axis of the turntable 32, and an upper mold 33 arranged on the turntable 32.

[0049] During actual use, the turntable 32 is driven to rotate by the driving assembly so that one of the lower molds 34 is in a position to be docked with the transfer station 4, and the other lower mold 34 cooperates with the upper mold 33 for injection molding. The finished product 100 injection-molded in the lower mold 34 docked with the transfer station 4 is first removed by the transfer station 4, and then the PIN needle is placed in the lower mold 34 through the transfer station 4.

[0050] In the above design, the structural design and specific implementation of the injection molding station 3 can alternately accept PIN needles through the two lower molds 34, thereby effectively improving the work efficiency.

[0051] Specifically: Figure 7 As shown, the transfer station 4 includes a fixed base 41, a No. 4 robot arm 42 arranged on the fixed base 41, an installation component 43 arranged at the output end of the No. 4 robot arm 42, a PIN needle transfer component 44 and a finished product transfer component 45 arranged on the installation component 43, the PIN needle transfer component 44 is used to transfer the PIN needle from the PIN needle processing station 2 to the injection molding station 3, and the finished product transfer component 45 is used to transfer the finished product 100 from the injection molding station 3 to the material receiving mechanism 1.

[0052] During actual use, the No. 4 robot arm 42 drives the installation assembly 43 to drive the PIN needle transferring assembly 44 and the finished product transferring assembly 45 to move, so that the PIN needle transferring assembly 44 transfers the PIN needle from the PIN needle processing station 2 to the lower mold 34, and the finished product transferring assembly 45 is used to transfer the finished product 100 from the lower mold 34 to the material receiving mechanism 1.

[0053] In the above design, the structural design and specific implementation of the transfer station 4 facilitate the rapid transfer of the PIN needles and the finished product 100.

[0054] Specifically: Figure 5 As shown, the PIN needle feeding station also includes a detection mechanism 26, which includes a push plate 261, a supporting fixture 262 arranged on the No. 2 frame 21, a No. 5 cylinder 263 arranged on the No. 2 frame 21 for driving the push plate 261 to move relative to the supporting fixture 262, a No. 1 probe 264 arranged on the push plate 261, and a No. 2 probe arranged on the supporting fixture 262.

[0055] In actual use, after the finished product 100 transfer component adsorbs the finished product 100, under the drive of the No. 4 robot arm 42, the finished product 100 transfer component places the product on the support fixture 262, so that the No. 2 probe contacts one end of the PIN needle, but at this time the finished product 100 transfer component still maintains the adsorption of the finished product 100, and then the No. 5 cylinder 263 drives the push plate 261 to drive the No. 1 probe 264 to contact the other end of the PIN needle.

[0056] In the above design, the structural design of the detection mechanism 26 facilitates the detection of whether the PIN needle of the finished product 100 is conductive.

[0057] The second embodiment provided by the present application is a lamp housing injection molding method: the PIN pin is shaped and aligned at the PIN pin processing station 2, and then the PIN pin is transferred to the PIN pin and shell injection molding station 3 for injection molding using the transfer station 4, so that the PIN pin and the injection-molded shell form a finished product 100, and then the finished product 100 is transferred to the material receiving mechanism 1 through the transfer station 4.
