Description

Technical Field

[0001] This invention relates to the field of bolt fastening equipment technology, specifically to a device for reinforcing screws on automotive headlight housings. Background Technology

[0002] Vehicle lights are tools for illuminating roads when vehicles are driving at night, and also for issuing various vehicle driving signals. The manufacturing process of vehicle light housings requires the use of screws. However, it is impossible to ensure production accuracy by manually tightening a large number of screws. Therefore, automatic screw-driving machines are usually used.

[0003] Patent document CN221676376U discloses an automatic screw-driving device, including an electric screwdriver, a screw assembler, and a telescopic cylinder. The electric screwdriver has a detachable screwdriver bar. The screw assembler has an assembly slide along its length. The assembly slide has an assembly inlet connected to it. A screw insertion slide is also provided on one side of the assembly slide. The output port of the screw insertion slide is connected to the assembly slide.

[0004] In the aforementioned application document, when the screwdriver moves toward the mounting ring, it engages with the screw on the mounting ring and drives it to disengage from the mounting ring. The screwdriver is used to engage the screw on it with the workpiece to be screwed in order to perform the screw-driving work. However, the overall screw installation accuracy is low and cannot ensure the screw is securely installed, so it needs to be improved. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a device for reinforcing screws on automotive headlight housings, solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a screw reinforcement device for automotive headlight housings, comprising a workbench, a support frame and a guide rail fixedly connected to the top of the workbench, a top seat fixedly connected to the top of the support frame, a slide table slidably connected to the top of the guide rail, an electric push rod A and a screw arranging machine disposed on the top of the workbench, the output end of the electric push rod A fixedly connected to the slide table, a human-machine interface display screen disposed at the front end of the top seat, an air pump and a screw delivery pipe disposed on the side of the screw arranging machine, and a screw reinforcement mechanism disposed at the bottom of the top seat; the screw reinforcement mechanism includes an electric platform disposed at the bottom of the top seat, and a movable... The movable plate has a hydraulic cylinder at its bottom, and a lifting seat is fixedly connected to the output end of the hydraulic cylinder. An electric push rod B is fixedly installed at the front end of the lifting seat. A lifting plate is slidably connected to the front end of the lifting seat. A motor is fixedly installed on the top of the lifting plate. A screwdriver is fixedly connected to the motor through its output shaft. A screw cylinder is fixedly connected to the front end of the lifting seat. A temporary limiting mechanism is provided on the surface of the screw cylinder. A connecting plate is fixedly connected to the output end of the electric push rod B. The side of the connecting plate is fixedly connected to the lifting plate. An inlet pipe is fixedly connected through and to the side of the screw cylinder. An intermittent feeding mechanism is provided at the front end of the lifting seat. A washer conveying mechanism is provided on the side of the screw cylinder.

[0007] According to the above technical solution, the temporary limiting mechanism includes a connecting frame, the top of which is fixedly connected to a screw cylinder, a rotating shaft is rotatably connected to the inner side of the connecting frame, a clamping claw is fixedly connected to the surface of the rotating shaft, and a torsion spring is provided on the surface of the rotating shaft.

[0008] According to the above technical solution, the end of the screw feeding pipe away from the screw arranging machine is fixedly connected to the inlet pipe. The bottom of the screwdriver is initially located inside the screw cylinder. The screw arranging machine arranges a large number of screws and transports the screws to the inlet pipe through the cooperation of the air pump and the screw feeding pipe.

[0009] According to the above technical solution, the two ends of the torsion spring are fixedly connected to the connecting frame and the clamping claws respectively. The number of clamping claws is set to four sets, and the screw can be temporarily limited by the four sets of clamping claws.

[0010] According to the above technical solution, the intermittent feeding mechanism includes a hydraulic chamber, a rotating rod, a slider, a limiting column, and a groove. The hydraulic chamber and the limiting column are both fixedly connected to the front end of the lifting seat. A piston rod A is slidably connected inside one end of the hydraulic chamber. A gear rod A is fixedly connected to the end of the piston rod A away from the hydraulic chamber. The rotating rod is rotatably connected to the front end of the lifting seat. A gear is fixedly connected to the front end of the rotating rod. The slider is slidably connected to the front end of the lifting seat. A gear rod B is fixedly connected to the side of the slider. A telescopic spring is provided inside the slider. An arc-shaped block is slidably connected inside the slider through the telescopic spring. A piston rod B is slidably connected inside the other end of the hydraulic chamber. A partition is fixedly connected to the end of the piston rod B away from the hydraulic chamber. A return spring is sleeved on the surface of the piston rod B. The groove is opened at the rear end of the connecting plate. A compression spring is provided inside the groove. A protrusion is slidably connected inside the groove through the compression spring.

[0011] According to the above technical solution, the protrusion is initially located above the arc-shaped block. The elastic potential energy of the compression spring is greater than that of the extension spring. When the protrusion moves downward, it will make direct contact with the arc-shaped block, causing the arc-shaped block and the slider to move downward. When the slider moves downward to the bottom and can no longer move downward, the protrusion will be squeezed and retract into the groove.

[0012] According to the above technical solution, both rack A and rack B are meshed with gears, the partition is connected to the inlet pipe through and in a sliding manner, when rack B moves downwards, it will drive rack A to move upwards through the gears, and when the partition is inside the inlet pipe, it will prevent the screw from entering the screw cylinder.

[0013] According to the above technical solution, the washer conveying mechanism includes a sensor and a fixed cylinder. The sensor is located at the top of the inlet pipe, and the fixed cylinder is connected through and fixedly connected to the side of the screw cylinder. An electric push rod C is provided on the side of the fixed cylinder, and a push plate is fixedly connected to the output end of the electric push rod C. A PLC control module is provided at the top of the electric push rod C.

[0014] According to the above technical solution, the bottom of the sensor is close to the top of the partition, and the top of the fixed cylinder has an opening through which a gasket can be added into the fixed cylinder.

[0015] According to the above technical solution, the rear end of the sensor is provided with a wire, and the sensor is electrically connected to the PLC control module through the wire. Each time the top of the partition separates from the sensor, it transmits a signal to the PLC control module through the wire to activate the electric push rod C to drive the push plate to move.

[0016] This invention provides a device for reinforcing screws on automotive headlight housings. It offers the following advantages:

[0017] (1) The present invention enables the screw arranging machine to arrange a large number of screws and transport the screws to the inlet pipe through the cooperation of the air pump and the screw conveying pipe. The hydraulic cylinder can be turned on to drive the lifting seat to move downward, and the electric push rod B can be turned on to drive the lifting plate to move downward. The screwdriver descends to drive the screw into the screw hole. At the same time, the motor drives the screwdriver to rotate to tighten the screw. The overall operation is stable, the degree of automation is high, and the tightening effect of the screw is better.

[0018] (2) By setting up an intermittent feeding mechanism, the screw arranging machine arranges a large number of screws and delivers the screws to the inlet pipe through the cooperation of the air pump and the screw conveying pipe. During the downward movement of the screwdriver, the partition intermittently opens the inlet pipe and quickly returns to its original position through the cooperation of components such as the hydraulic chamber, slider, and arc block, ensuring that only one screw enters the screw cylinder at a time, thereby improving the stability of the overall device operation.

[0019] (3) The present invention, through the setting of the washer conveying mechanism, allows the addition of washers to the fixed cylinder when it is necessary to use washers to fasten screws. When the partition opens the inlet pipe intermittently and quickly closes, the push plate moves to the right by a distance through the cooperation of components such as sensors, wires, and PLC control modules, squeezing a set of washers into the screw cylinder, and then combining with the screw when the screw falls.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] Please see Figures 1-12One embodiment of the present invention is: a screw reinforcement device for automotive headlight housings, comprising a workbench 1, a support frame 2 and a guide rail 4 fixedly connected to the top of the workbench 1, a top seat 3 fixedly connected to the top of the support frame 2, a slide table 5 slidably connected to the top of the guide rail 4, an electric push rod A6 and a screw arranging machine 8 disposed on the top of the workbench 1, the output end of the electric push rod A6 being fixedly connected to the slide table 5, a human-machine interface display screen 7 disposed at the front end of the top seat 3, an air pump 9 and a screw delivery pipe 10 disposed on the side of the screw arranging machine 8, and a screw reinforcement mechanism 11 disposed at the bottom of the top seat 3; the screw reinforcement mechanism 11 includes an electric table 1 11. An electric platform 111 is located at the bottom of the top seat 3. A movable plate 112 is located at the bottom of the electric platform 111. A hydraulic cylinder 113 is located at the bottom of the movable plate 112. A lifting seat 114 is fixedly connected to the output end of the hydraulic cylinder 113. An electric push rod B1110 is fixedly installed at the front end of the lifting seat 114. A lifting plate 115 is slidably connected to the front end of the lifting seat 114. A motor 116 is fixedly installed on the top of the lifting plate 115. A screwdriver 117 is fixedly connected to the motor 116 through its output shaft. A screw cylinder 118 is fixedly connected to the front end of the lifting seat 114. A temporary screwdriver is provided on the surface of the screw cylinder 118. The limiting mechanism 119 includes a connecting frame 1191. The top of the connecting frame 1191 is fixedly connected to the screw cylinder 118. A rotating shaft 1192 is rotatably connected to the inner side of the connecting frame 1191. A clamping claw 1193 is fixedly connected to the surface of the rotating shaft 1192. A torsion spring 1194 is provided on the surface of the rotating shaft 1192. Both ends of the torsion spring 1194 are fixedly connected to the connecting frame 1191 and the clamping claw 1193, respectively. The number of clamping claws 1193 is set to four sets. The screw can be temporarily limited by the four sets of clamping claws 1193. The output end of the electric push rod B1110 is fixedly connected to... There is a connecting plate 1111, the side of the connecting plate 1111 is fixedly connected to the lifting plate 115, the side of the screw cylinder 118 is penetrated and fixedly connected to the inlet pipe 1112, the end of the screw conveying pipe 10 away from the screw arranging machine 8 is fixedly connected to the inlet pipe 1112, the bottom of the screwdriver 117 is initially located inside the screw cylinder 118, the screw arranging machine 8 arranges a large number of screws and conveys the screws to the inlet pipe 1112 through the cooperation of the air pump 9 and the screw conveying pipe 10, the front end of the lifting seat 114 is provided with an intermittent feeding mechanism 12, and the side of the screw cylinder 118 is provided with a washer conveying mechanism 13.

[0035] In use, the headlight housing is fixed to the top of the slide table 5. Activating the electric push rod A6 moves the slide table 5, while activating the electric platform 111 moves the moving plate 112 laterally. This helps to position the headlight housing where screws need to be installed. The screw arranging machine 8 arranges a large batch of screws and, through the cooperation of the air pump 9 and the screw delivery pipe 10, delivers the screws to the inlet pipe 1112, where they fall into the screw cylinder 118. Once inside the screw cylinder 118, the screws fall to the clamping claws 1193. The four sets of clamping claws 1193, in conjunction with the torsion springs 1194, temporarily limit the screws. Then, the hydraulic cylinder 113 lowers the lifting seat 114 to the appropriate position, and the electric push rod B1110 moves the connecting plate 1111 downwards. The downward movement of the connecting plate 1111... The lifting plate 115 moves downward, which in turn moves the screwdriver 117 downward. The screwdriver 117 then drives the bolt inside the screw sleeve 118 into the screw hole of the lamp housing. During this process, the clamping claw 1193 is squeezed and deflects outward, allowing the screw to come off. Then, the torsion spring 1194 drives the clamping claw 1193 to return to its original position. Subsequently, the motor 116 starts and drives the screwdriver 117 to rotate through its output shaft to tighten the screw. Finally, the hydraulic cylinder 113 drives the lifting seat 114 to rise and return to its original position. The electric push rod B1110 drives the connecting plate 1111 to move upward, which in turn drives the lifting plate 115 to move upward and return to its original position. This cycle is repeated to tighten the screw. The overall operation is stable, highly automated, and provides a better tightening effect on the screw.

[0036] Please see Figures 1-12Based on the above embodiments, in another embodiment of the present invention, the intermittent feeding mechanism 12 includes a hydraulic chamber 121, a rotating rod 124, a slider 127, a limiting post 126, and a groove 1215. The hydraulic chamber 121 and the limiting post 126 are both fixedly connected to the front end of the lifting seat 114. A piston rod A122 is slidably connected inside one end of the hydraulic chamber 121. A gear rod A123 is fixedly connected to the end of the piston rod A122 away from the hydraulic chamber 121. The rotating rod 124 is rotatably connected to the front end of the lifting seat 114. A gear 125 is fixedly connected to the front end of the rotating rod 124. The slider 127 is slidably connected to the front end of the lifting seat 114. A gear rod B1218 is fixedly connected to the side of the slider 127. A telescopic spring 1 is provided inside the slider 127. 28. An arc-shaped block 129 is slidably connected inside the slider 127 via a telescopic spring 128. A piston rod B1212 is slidably connected inside the other end of the hydraulic chamber 121. A partition plate 1213 is fixedly connected to the end of the piston rod B1212 away from the hydraulic chamber 121. Both the rack A123 and the rack B1218 mesh with the gear 125. The partition plate 1213 passes through and is slidably connected to the inlet pipe 1112. When the rack B1218 moves downward, it will drive the rack A123 to move upward through the gear 125. When the partition plate 1213 is inside the inlet pipe 1112, it will prevent the screw from entering the screw cylinder 118. A return spring 1214 is sleeved on the surface of the piston rod B1212. A groove 1215 is formed at the rear end of the connecting plate 1111. A compression spring 1216 is installed inside the groove 1215. A protrusion 1217 is slidably connected inside the groove 1215 via the compression spring 1216. The protrusion 1217 is initially located above the arc-shaped block 129. The elastic potential energy of the compression spring 1216 is greater than that of the extension spring 128. When the protrusion 1217 moves downward, it will make direct contact with the arc-shaped block 129, causing the arc-shaped block 129 and the slider 127 to move downward. When the slider 127 moves downward to the bottom and can no longer move downward, the protrusion 1217 will be compressed and retract into the groove 1215. The washer conveying mechanism 13 includes a sensor 131 and a fixed cylinder 132. The sensor 131 is located at the top of the inlet pipe 1112, and the fixed cylinder 132 passes through and is fixedly connected to it. On the side of the screw cylinder 118, the bottom of the sensor 131 is close to the top of the partition 1213. The top of the fixed cylinder 132 has an opening through which a washer can be added. An electric push rod C133 is provided on the side of the fixed cylinder 132. The output end of the electric push rod C133 is fixedly connected to the push plate 134. A PLC control module 135 is provided on the top of the electric push rod C133. A wire 136 is provided at the rear end of the sensor 131, and the sensor 131 is electrically connected to the PLC control module 135 through the wire 136. Each time the top of the partition 1213 separates from the sensor 131, it transmits a signal to the PLC control module 135 through the wire 136 to activate the electric push rod C133 and drive the push plate 134 to move.

[0037] In use, the screw arranging machine 8 arranges a large number of screws and, through the cooperation of the air pump 9 and the screw delivery pipe 10, delivers the screws to the inlet pipe 1112. The partition plate 1213, located inside the inlet pipe 1112, prevents the screws from entering the screw cylinder 118. As the electric push rod B1110 moves the connecting plate 1111 downwards, the protrusion 1217 moves downwards and comes into direct contact with the arc-shaped block 129, causing the arc-shaped block 129 and the slider 127 to move downwards. The downward movement of the slider 127 causes the rack B1218 to move downwards. When the rack B1218 moves downwards, it drives the rack A123 upwards via the gear 125. The upward movement of the rack A123 then drives the piston rod A122 to move upwards. When piston rod A122 moves upward, the hydraulic pressure inside the hydraulic chamber 121 near the piston rod A122 creates a negative pressure, causing piston rod B1212 to move downward. The downward movement of piston rod B1212 causes the partition 1213 to move downward, opening the inlet pipe 1112. The return spring 1214 is compressed. When slider 127 moves downward to its lowest point and can no longer move downward, protrusion 1217 is subjected to significant pressure and retracts into groove 1215. Compression spring 1216 is compressed, and protrusion 1217 moves past arc-shaped block 129 to below it. Subsequently, compression spring 1216 causes protrusion 1217 to pop out and return to its original position. At this time, return spring 1214 rebounds, causing piston rod B1212 to move downward. The stopper rod B1212 and the partition plate 1213 quickly return to their original positions, and the inlet pipe 1112 is closed again. Hydraulic pressure causes the piston rod A122 and the rack A123 to move downwards, while the gear 125 drives the rack B1218 to move upwards. The slider 127 moves upwards and contacts the limiting post 126. When the connecting plate 1111 moves upwards, the protrusion 1217 contacts the arc surface of the arc block 129. At this time, under the restriction of the limiting post 126, the slider 127 will not move upwards. The arc surface of the arc block 129 is squeezed into the slider 127, allowing the protrusion 1217 to pass through. The telescopic spring 128 is compressed, and then the telescopic spring 128 drives the arc block 129 to return to its original position, passing through the partition... Plate 1213 intermittently opens the inlet pipe 1112 and quickly closes it, ensuring that only one screw enters the screw cylinder 118 at a time, which improves the stability of the overall device operation. When it is necessary to use washers to fasten the screws, washers can be added to the fixed cylinder 132. During the process of plate 1213 intermittently opening the inlet pipe 1112 and quickly closing it, each time the top of plate 1213 separates from sensor 131, it transmits a signal to PLC control module 135 through wire 136 to activate electric push rod C133 to drive push plate 134 to move. Each time push plate 134 moves a certain distance to the right, it squeezes a set of washers into screw cylinder 118, which are then combined with the screws when the subsequent screws fall.

[0038] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
