[0002] As automobiles have gradually become the main means of transportation for people, headlamps, as an important part of vehicles, need to be precisely installed during the production process. Headlamps are mainly composed of a lamp housing and a bulb. Most lamp housings are made of plastic materials, which have the advantages of light weight, low cost, easy molding, etc., and also have good weather resistance and impact resistance. When processing the lamp housing, screws are required to install the inner lining, outer shell, and transparent shell of the lamp housing together.

[0003] Currently, when screwing the lamp housing in the existing manner, the assembled lamp housing is usually placed on a mold, and then the mold is moved under the automatic screwing machine to control the automatic screwing machine to perform the screwing operation on the lamp housing. However, during the operation, due to the inconsistent thickness of the lamp housings of different types of vehicles, different fixing molds need to be used to fix the lamp housing each time, and the mold needs to be replaced each time the product model is changed, resulting in low production efficiency and increased production costs. Summary of the Invention

[0004] In view of this, the present invention provides a device for screwing the lamp housing of an automobile headlamp.

[0005] The technical solution is as follows: A device for screwing the lamp housing of an automobile headlamp includes a workbench, a two-axis moving mechanism, a screw gun, a screw feeding machine, an electric guide rail, a placing mechanism, and a fixing mechanism. The two-axis moving mechanism is installed on the top of the workbench, and the moving body of the two-axis moving mechanism is installed with a screw gun. The screw feeding machine is installed on the top of the workbench. The two-axis moving mechanism can drive the screw gun to align with the feeding end of the screw feeding machine.

Detailed implementation manners

[0032] Although the present invention may be described with respect to a particular application or industry, those skilled in the art will recognize a broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as above, below, upward, downward, etc. are used to describe the drawings and do not represent a limitation on the scope of the present invention as defined by the appended claims. Any numerical designations such as first or second are merely illustrative and are not intended to limit the scope of the present invention in any way.

[0033] An automobile headlight housing screwing device, as Figures 1-6 shown, includes a workbench 1, a two-axis moving mechanism 2, a screw gun 21, a screw feeding machine 3, an electric guide rail 4, a placing mechanism and a fixing mechanism. A two-axis moving mechanism 2 is installed at the rear side of the top of the workbench 1. A screw gun 21 is installed on the moving body of the two-axis moving mechanism 2. A screw feeding machine 3 is installed in the middle of the rear side of the workbench 1. The two-axis moving mechanism 2 can drive the screw gun 21 to align with the feeding end of the screw feeding machine 3. Electric guide rails 4 are installed on both the left and right sides of the top of the workbench 1. A placing mechanism is provided on the electric guide rails 4. A fixing mechanism for fixing the headlight housing 100 is provided on the placing mechanism.

[0034] As Figures 2-4 shown, the placing mechanism includes a feeding tray 51, a mounting plate 52 and a guiding taper sleeve 53. Feeding trays 51 are installed on the moving bodies of the two electric guide rails 4. The mounting plate 52 is rotatably connected to the rear side of the feeding tray 51. The headlight housing 100 can be placed on the mounting plate 52. A plurality of positioning holes are uniformly spaced on the mounting plate 52. The positions of the positioning holes are consistent with the positions of the screw holes of the headlight housing 100. After the headlight housing 100 is placed, the screw holes on the headlight housing 100 are aligned with the positioning holes. A guiding taper sleeve 53 is provided at the positioning holes. The screw can be guided through the guiding taper sleeve 53. Feeding grooves are formed on both sides of the feeding tray 51.

[0035] As Figure 5 and Figure 6As shown, the fixing mechanism includes a positioning column 61, a first elastic member 62, a fixing strip 63, a sliding rod 64, and an internally threaded sleeve 65. A plurality of positioning columns 61 are slidably connected to the inner bottom of the material discharge groove of the material discharge tray 51 at equal intervals. A first elastic member 62 is connected between the positioning column 61 and the material discharge tray 51. The first elastic member 62 is a connecting spring. A sliding rod 64 is slidably connected to the middle of the material discharge tray 51. The sliding rod 64 can slide back and forth along the material discharge tray 51. Fixing strips 63 are evenly spaced and connected to both the left and right sides of the sliding rod 64. The movement of the fixing strip 63 can abut against the positioning column 61 to fix the positioning column 61. An internally threaded sleeve 65 is rotatably connected to the middle of the front side of the material discharge tray 51. The internally threaded sleeve 65 is in threaded cooperation with the front side of the sliding rod 64, so that the rotation of the internally threaded sleeve 65 can drive the sliding rod 64 to move back and forth through the thread, thereby driving the fixing strip 63 to move.

[0036] When it is necessary to screw the headlight housing 100 of the car, the device can be used. When in use, the headlight housing 100 is first placed in the discharge grooves on the left and right sides of the mounting plate 52. When placed, the screw holes on the headlight housing 100 are aligned with the bottom of the guide cone sleeve 53, and then the mounting plate 52 is covered on the discharge tray 51. During the covering process, the mounting plate 52 will squeeze the headlight housing 100, so that the headlight housing 100 moves downward to squeeze the positioning column 61 downward, and the elastic member 62 is compressed, and the positioning column is pressed by the elastic member 62. 61 applies an upward thrust, so that the positioning column 61 presses against the lamp housing 100, and assists in positioning the lamp housing 100. At this time, the internal thread sleeve 65 is rotated again. When the internal thread sleeve 65 rotates, it can drive the sliding rod 64 to move through the thread. When the sliding rod 64 moves, it can drive the fixing bar 63 to move. After the fixing bar 63 moves, it can press against the positioning column 61, and assist in fixing the positioning column 61. After the operation is completed, the lamp housing 100 is fixed. At this time, the lamp housing 100 is located inside the discharge tray 51, and then the electric guide rail 4 is controlled to bring The material discharging tray 51 moves backward, and in the actual operation process, according to the different thicknesses of the lamp housing 100, the positioning column 61 can be pressed by the elastic member 62 to fix the lamp housing 100 to prevent the position of the lamp housing 100 from shifting. Then the material discharging tray 51 continues to move to drive the mounting plate 52 to move below the screw gun 21. At this time, the two-axis moving mechanism 2 can be controlled to drive the screw gun 21 to move to the screw feeder 3 to absorb the screw, so that the screw is located at the bottom of the screw gun 21, and then the screw gun 21 is controlled to move downward. The screw is moved to pass through the guide cone sleeve 53 and abut against the screw hole of the lamp housing 100. At this time, the screw gun 21 is controlled to rotate and put the screw into the screw hole. Then, the screw gun 21 is brought to the material and screwed through the two-axis moving mechanism 2. This process is repeated repeatedly. The lamp housing 100 can be screwed using the device. When placing the lamp housing 100, lamp housings 100 of different thicknesses can be fixed without replacing the mold, which is more convenient to operate.

[0037] like Figures 7-11 As shown, a guide mechanism is also included, and the guide mechanism includes a sleeve frame 71, a sliding frame 72, an elastic member 73 and a guide sleeve 74. The bottom of the screw gun 21 is connected to the sleeve frame 71, and the lower part of the sleeve frame 71 is slidably connected to the sliding frame 72. An elastic member 73 is connected between the sliding frame 72 and the sleeve frame 71, and the elastic member 73 is a reset spring. The bottom of the sliding frame 72 is connected to the guide sleeve 74, and the bottom edge of the guide sleeve 74 is provided with an inclined chamfer to facilitate the insertion of the screw into the guide sleeve 74.

[0038] When the screwdriver 21 moves to the screw feeder 3 to pick up screws, the screws will pass through the guide sleeve 74 and enter the screwdriver 21. When the screws pass through the guide sleeve 74, the inclined chamfer opened at the inner bottom of the guide sleeve 74 can guide the screws to avoid the angle deviation of the screws. During the process of driving the screws, the screwdriver 21 moves downward to drive the sliding frame 72 and the guide sleeve 74 to move downward. After the guide sleeve 74 moves downward and contacts the guide cone sleeve 53, the guide sleeve 74 no longer moves downward. At this time, when the screwdriver 21 continues to move downward, it will drive the screws and the sleeve frame 71 to move downward, and the second elastic member 73 is compressed, so that the screws can move out of the guide sleeve 74. In this way, the screws can be guided when picking up the screws, and the angle deviation of the screws can be avoided.

[0039] As Figure 12 and Figure 13 shown, it further includes a transmission mechanism. The transmission mechanism includes a rack 81, a driving gear 82 and a transmission gear 83. The rack 81 is connected to both the left and right sides of the top of the workbench 1. The driving gears 82 are rotatably connected to the mutually close sides of the two feeding trays 51. The rack 81 is located at the moving track of the driving gear 82, so that the driving gear 82 will be engaged with the rack 81 when moving and be driven by the rack 81 to rotate. The transmission gears 83 are connected to the mutually close sides of the transmission shafts of the two mounting plates 52. The transmission gear 83 is engaged with the driving gear 82, so that the driving gear 82 will drive the transmission gear 83 to rotate when rotating, thereby driving the mounting plate 52 to rotate and cover the feeding tray 51.

[0040] When the feeding tray 51 moves backward, it can drive the driving gear 82 to move backward together. When the driving gear 82 moves backward, it can be engaged with the rack 81 and be driven by the rack 81 to rotate. When the driving gear 82 rotates, it will drive the transmission gear 83 to rotate. When the transmission gear 83 rotates, it can drive the mounting plate 52 to rotate. After the mounting plate 52 rotates, it can cover the feeding tray 51. At this time, the driving gear 82 is also disengaged from the rack 81. In this way, the mounting plate 52 can be automatically driven to cover the feeding tray 51, and the operation is more convenient.

[0041] As Figure 14 shown, it further includes an alignment post 91 and an alignment sleeve 92. Three alignment sleeves 92 are arranged on the front side of the top of the feeding tray 51, and three alignment posts 91 are arranged on the upper part of the front side of the mounting plate 52. When the mounting plate 52 covers the feeding tray 51, the alignment posts 91 are inserted into the alignment sleeves 92 to assist in limiting the mounting plate 52.

[0042] As Figure 11As shown, it further includes a rubber sleeve 10. The rubber sleeve 10 is arranged at the bottom edge of the guiding conical sleeve 53. When the headlight housing 100 is placed on the mounting plate 52, the rubber sleeve 10 can align with the hole positions on the headlight housing 100 to assist in fixing the headlight housing 100. At the same time, the rubber sleeve 10 can also increase the friction between the headlight housing 100 and the guiding conical sleeve 53 to prevent the headlight housing 100 from falling off.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
