Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive lighting assembly technology, and in particular to equipment for hot-embedded screws for automotive lighting assemblies. Background Technology
[0002] Vehicle lights are tools for illuminating roads at night and also for issuing various vehicle driving signals. The design of headlights for new energy vehicles tends to be larger and longer, which requires more screws to be embedded in the manufacturing process to achieve a stable assembly. The common method of embedding mounting screws is to pre-place the screw inserts into the mold cavity during the injection molding of the lamp housing and remove them after molding. However, this method has the following significant problems: (1) Low yield and high risk of scrap: Due to the limited operating space, if there is a positioning deviation or poor injection molding during the molding process, it will lead to defects in the connection between the screw and the housing, resulting in the scrapping of the entire part and waste of materials and costs. (2) Production efficiency and cost bottleneck: The process of pre-embedding screw inserts increases the complexity of production, which not only prolongs the molding cycle, but also further increases the manufacturing cost due to manual intervention or rework requirements. Utility Model Content

[0026] The present invention will be further described below with reference to the accompanying drawings.
[0027] like Figures 1-7 As shown, this utility model provides a first embodiment of a device for heat-embedded screws in automotive lamp components, including a workbench 1, on which a heating and transfer mechanism 2 is provided; the heating and transfer mechanism 2 includes a conveying track 21 for transporting screws 100, and a receiving seat 22 is provided at the outlet of the conveying track 21; a heating device 3 for heating the screws 100 is provided on the side of the conveying track 21; a pneumatic finger 4 is provided on the front side of the receiving seat 22, and the pneumatic finger 4 is driven by a transfer component 5 to facilitate the transfer of the bolts in the receiving seat 22 to the heating device 3; the workbench 1 is also provided with a robotic arm 6 for transferring the heated screws 100 to the automotive lamp housing for heat embedding.
[0028] The receiving seat 22 has a placement groove for accommodating the screw 100 output from the conveying track 21.
[0029] During operation, the screw 100 is transported to the placement slot of the receiving seat 22. The transfer component 5 transfers the screw 100 in the placement slot to the heating device 3. The heating device 3 heats the screw 100. After heating, the heated screw 100 is transferred to the headlight housing by the robotic arm 6. The screw 100 is then embedded into the headlight housing for heat embedding, which can effectively improve work efficiency and reduce the production cost of the headlight housing.
[0030] In one embodiment of the present invention, the heating and transfer mechanism 2 further includes a vibratory feeder 23 fixed on the workbench 1, and the discharge end of the vibratory feeder 23 is connected to the conveying track 21 to output screws 100 through the conveying track 21.
[0031] The vibratory feeder 23 ensures a continuous output of screws 100. In addition, the conveyor track 21 has a T-shaped cross section to facilitate the limiting of screws 100.
[0032] The transfer assembly 5 includes a first base plate 51 fixed to the front side of the receiving seat 22. A first horizontal slide cylinder 52 is fixed on the first base plate 51. A first support frame 53 is fixed on the slide of the first slide cylinder 52. A second vertical slide cylinder 54 is fixed on the first support frame 53. The pneumatic finger 4 is horizontally fixed on the slide of the second slide cylinder 54 and faces the receiving seat 22. Each of the two gripping fingers of the pneumatic finger 4 is fixed with a gripping block 41. The two gripping blocks 41 form a gripper for gripping the screw 100.
[0033] The second slide cylinder 54 drives the pneumatic finger 4 to move downward, causing the gripper to move to the screw 100 located in the placement slot. The pneumatic finger 4 drives the gripper to clamp the screw 100. Then, the second slide cylinder 54 drives the pneumatic finger 4 to move upward. Then, the first slide cylinder 52 drives the first support frame 53 to move to the right, thereby moving the pneumatic finger 4 and the screw 100 to the right above the heating device 3. Finally, the second slide cylinder 54 drives the pneumatic finger 4 and the screw 100 to move downward. When the screw 100 moves to the heating device 3, the pneumatic finger 4 drives the gripper to open, placing the screw 100 in the heating device 3.
[0034] The heating device 3 includes a heating base 31, on which a heating tube 32 for inserting a screw 100 is provided. A coil (not shown) is wound around the outer wall of the heating tube 32. When the screw 100 is inserted into the heating tube 32, the coil is energized to generate electromagnetic induction to heat the metal screw 100, causing eddy currents to be generated in the metal screw 100. Due to resistance, the screw 100 is Joule heated.
[0035] To facilitate the fixing of the car headlight housing, in one embodiment of this utility model, a limiting component 7 for limiting the headlight housing is provided on the front side of the heating and transfer mechanism 2; the limiting component 7 includes a second base plate 71 fixed on the workbench 1, and a plurality of first support seats 72 for supporting the headlight housing are horizontally fixed on the second base plate 71. The first support seats 72 have stepped surfaces 73 for placing the headlight housing; second support seats 74 are fixed at both the left and right ends of the second base plate 71, and the second support seats 74 have limiting blocks 75 for limiting the left and right ends of the headlight housing.
[0036] The left and right ends of the second base plate 71 are each fixed with a first fixing seat 76 located on the outside of the second support seat 74, and a first spinning cylinder 77 is fixed on the first fixing seat 76; a second fixing seat 78 is fixed on the second base plate 71 located on the rear side of the rear row first support seat 72, and a second spinning cylinder 79 is fixed on the second fixing seat 78.
[0037] The headlight housing is placed on the limiting assembly 7. A barcode scanner 10 is fixed to the second base plate 71 via a mounting base 9. When the barcode scanner 10 senses that the device is fixed, the stepped surface 73 of the first support base 72 supports the entire body of the headlight housing, and the limiting block 75 supports the left and right ends of the headlight housing. Then, two first spinning cylinders 77 drive their pressure rods to press down on the left and right ends of the headlight housing, thereby limiting the left and right ends of the headlight housing; two second spinning cylinders 79 drive their pressure rods to press down on the entire body of the headlight housing, thereby limiting the entire body of the headlight housing.
[0038] In one embodiment of the present invention, a heating transfer mechanism 2 is symmetrically arranged on the right side of the workbench 1, so that a dual-station can be achieved through two heating transfer mechanisms 2, thereby accelerating the heat embedding efficiency of the screw 100.
[0039] In one embodiment of the present invention, a linear guide rail 8 is also fixed on the first base plate 51. The linear guide rail 8 slides with the bottom of the first support frame 53 to improve the stability of the first support frame 53 during movement.
[0040] The robotic arm, vibratory feeder, linear guide, slide cylinder, pneumatic finger, telescopic cylinder, and barcode scanner in this utility model are all existing technologies, which are already clearly understood by those skilled in the art, and will not be described in detail here.
