Description

Technical Field

[0001] The present invention relates to the technical field of lighting fixture production, and in particular to a lighting fixture assembly machine which is convenient for positioning and assembling. Background Art

[0002] Light bulbs are common lighting fixtures in our daily lives. LEDs are made of an electroluminescent semiconductor chip, which is cured onto a bracket with silver or white glue. Silver or gold wires are then used to connect the chip to the circuit board. Epoxy resin is used to seal the edges to protect the internal core wires, and the outer casing is installed. This is why LEDs are highly shock-resistant. An LED (Light Emitting Diode) is a solid-state semiconductor device that converts electrical energy into visible light. It can directly convert electricity into light. The heart of an LED is a semiconductor wafer. One end of the wafer is attached to a bracket, with one end serving as the negative terminal and the other end connected to the positive terminal of a power source. The entire wafer is encapsulated in epoxy resin. The semiconductor wafer consists of two parts: a P-type semiconductor, where holes predominate, and an N-type semiconductor, where electrons predominate. When these two semiconductors are connected, a PN junction is formed. When current flows through the wafer, electrons are pushed to the P region, where they recombine with holes and emit energy as photons. This is the principle of LED light.

[0003] in, LED The lamp holder of the light bulb used for external devices needs to be rotated and fixed after being placed on the LED bulb base during the assembly and production process. When the lamp holder is placed on the LED bulb base, due to some deviations, the lamp holder will be in an offset state on the LED bulb base and cannot be aligned with the LED bulb base, which affects the subsequent lamp holder rotation assembly and fixing process. Therefore, in order to maintain the stability of the LED bulb assembly process, it is necessary to invent a lighting fixture assembly machine that is easy to position and assemble.

[0020] Working principle: When assembling LED bulbs, the gear roller driven by the motor rotates, and another gear roller is driven through the gear chain, so that the gear chain drives the connected basket 1 to move and start loading. When the gear roller on the left end rotates, the incomplete gear fixed on the bottom side will be used to indirectly drive gear 1. Gear 1 is connected to gear 2 connected to the turntable, so that the turntable connected to basket 2 is indirectly rotated, changing the angle to move the idle basket 2 to the bottom side of the loading and unloading robot arm, and the loading and unloading robot arm is used to load the LED bulb base on basket 1 to the idle basket 2. The screw driven by the motor drives the connecting arc plate connected to it, so that the teeth on the connecting arc plate mesh with gear 5 connected to the worm, so that the worms at both ends mesh and drive the corresponding gears 3 and 4 respectively. One of the gears 3 meshes and drives the other gear 3 to rotate in the opposite direction.

The offset lamp head on the bulb base is corrected to prevent it from offsetting and tilting. The raised connecting arc plate simultaneously drives the push rod connected to the right end to rise, pushes the rear end of the connecting rod upward, and rotates at the rear end of the connecting rod, so that the rear end of the connecting rod is tilted and the front end is pressed down, so that the limiting groove on the right side of the front end contacts the connecting part on the left side of the top of the tightening sleeve, thereby pushing the tightening sleeve to move downward. When the bottom end of the tightening sleeve is sleeved on the lamp head, the lamp head is rotated so that the lamp head is tightened and fixed on the LED bulb base. One of the gears four meshes and transmits the other gear four to rotate in the opposite direction. Driven by the two rotating gears four, the cutting knife connected to the base connected thereto rotates and rotates in opposite directions to close, so that the blade surfaces of the two cutting knives abut together, thereby cutting the excess leads exposed on the LED bulb base on the basket body two on its left side. After completing the above assembly process, the LED bulb base on the basket body two will leave the basket body two by cutting and be put into the next assembly work.

[0021] The present invention provides a lighting fixture assembly machine that facilitates positioning and assembly. It has the following beneficial effects:

[0023] 2. The present invention can add an assembly process for trimming the leads while positioning the lamp holder by connecting the arc plate, thereby improving the flexibility and versatility of the assembly equipment, thereby greatly improving production efficiency and enhancing the integrated design of the LED bulb assembly process.

[0024] 3. The present invention uses a single drive source to synchronously drive the loading and assembly process transportation of the LED bulb base, reducing the number of drive sources, thereby maximizing the utilization efficiency of the single drive source, thereby reducing energy consumption and reducing production expenses.

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Example:

[0037] An embodiment of the present invention provides a lighting fixture assembly machine that facilitates positioning and assembly, comprising:

[0038] See attached Figure 1 - Attachment Figure 3 , chassis 1, the two toothed rollers 2 rotatably connected to the right end of the top side of the chassis 1 are connected through a toothed chain 3, the top side of the chassis 1 is rotatably connected to a turntable 4 at the left end, an incomplete gear 7 is fixedly connected to the bottom side of the left end toothed roller 2, the bottom side of the turntable 4 is fixedly connected to a gear 2 9, the incomplete gear 7 is meshed with a gear 1 8 on the side close to the gear 2 9, the top side of the gear 1 8 is rotatably connected to the bottom side of the chassis 1, a plurality of baskets 5 are fixedly connected to the outer periphery of the toothed chain 3, a plurality of baskets 2 6 are fixedly connected to the outer periphery of the top side of the turntable 4, motors are installed on the bottom side of the screw 18 and the bottom side of the right end toothed roller 2, and a loading and unloading robot arm 26 is installed on the front end of the middle part of the top side of the chassis 1;

[0039] Specifically, both basket 1 5 and basket 2 6 are used to hold and place LED bulb bases. Basket 1 5, connected to the gear chain 3, is used to transport LED bulb bases that have not yet been installed with a lamp cap. With the assistance of the loading and unloading robot 26, the LED bulb base is placed on basket 2 6 connected to the turntable 4. The rotating basket 2 6 then transfers the LED bulb base to the assembly production process. When the right-end gear roller 2 is driven by the motor, it drives another gear roller 2 through the gear chain 3, causing the gear chain 3 to drive the connected basket 1 5 to move and begin loading. When the left-end gear roller 2 rotates, it indirectly drives gear 1 8 via the incomplete gear 7 fixed on its bottom side. Gear 1 8 and gear 2 9 connected to the turntable 4 indirectly rotate the turntable 4 connected to basket 2 6, changing its angle, and moving the idle basket 2 6 to the bottom side of the loading and unloading robot 26. The loading and unloading robot 26 then loads the LED bulb base from basket 1 5 onto the idle basket 2 6.

[0040] See attached Figure 3 , shell 10, shell 10 is located on the rear side of the turntable 4, the bottom side of the shell 10 is fixedly connected to the chassis 1, the front bottom end of the shell 10 is internally rotatably connected to two gears 3 12, the two gears 3 12 are engaged with each other, and the top side of the gear 3 12 is fixedly connected with a positioning buckle 13, and a slide groove is opened at the top of the front side of the shell 10, and the slide groove is connected to a tightening sleeve 24 through a return spring. The tightening sleeve 24 is located on the top side of one of the baskets 2 6;

[0041] Specifically, both positioning buckles 13 are provided with notches, and the two positioning buckles 13 are mirror-symmetrical. When driven by the two gears 3 12, the positioning buckles 13 rotate in opposite directions and close together, merging the notches on the two positioning buckles 13 into a circular hole, thereby correcting the offset lamp head and preventing it from shifting and tilting. The tightening sleeve 24 is built into a motor. When the bottom end of the tightening sleeve 24 is driven by the motor, it can rotate the lamp head when the bottom end of the tightening sleeve 24 is placed on the lamp head, thereby tightening the lamp head to the LED bulb base.

[0042] See attached Figure 3 and attached Figure 9 , Shell 2 11, Shell 2 11 is located on the left side of the turntable 4, the bottom side of the shell 2 11 is fixedly connected to the chassis 1, and the right end of the shell 2 11 is rotatably connected to two gears 4 14. The two gears 4 14 are engaged with each other, and the top side of the gear 4 14 is connected to a cutting knife 16, which is fixedly connected to a base 15 on the top side of the gear 4 14. The bottom end of the cutting knife 16 is slidably connected to the inner wall of the base 15, and a tightening bolt 25 is threadedly connected to the outer wall of the base 15. The side of the tightening bolt 25 close to the cutting knife 16 is pressed against the outer wall of the bottom end of the cutting knife 16;

[0043] Specifically, during the assembly process of an LED bulb, a lead wire for connecting to the outside of the bulb needs to be installed. After the lamp holder is installed, the lead wire needs to be cut off with one side of the lamp holder as the reference surface. The cutter 16 connected to the base 15 connected thereto is driven by the rotating two gears 14 to rotate and close in opposite directions, so that the blades of the two cutters 16 abut against each other, thereby cutting the excess lead wire exposed outside. By loosening the tightening bolt 25, the bottom end of the cutter 16 can be released from the tightening bolt 25, so that it can slide on the base 15, and then the height of the cutter 16 can be adjusted to adapt to the lamp holder reference surface on the base of LED bulbs of different specifications to cut the lead wire. By adding new assembly processes to the equipment and synchronizing them, the flexibility and versatility of the assembly equipment are improved, thereby greatly improving production efficiency and enhancing the integrated design of the LED bulb assembly process.

[0044] See attached Figure 2 - Attachment Figure 8, slide rod 17, slide rod 17 is fixedly connected to the left end of the top rear side of chassis 1, and a screw 18 is provided on the side of slide rod 17 away from turntable 4, and the bottom end of screw 18 passes through the bottom side of chassis 1 and is rotatably connected to chassis 1, and a connecting arc plate 19 is connected between slide rod 17 and screw 18, and one end of the middle part of connecting arc plate 19 is slidably connected to the outer wall of slide rod 17, and the other end of the middle part of connecting arc plate 19 is threadedly connected to the outer wall of screw 18, and the teeth at both ends of the connecting arc plate 19 close to the turntable 4 side are rotatably connected to the inner bottom end of the rear side of shell 10 and the inner left side of shell 2 11. A worm 21 is connected, and a gear 5 20 is fixedly connected to the side of the worm 21 close to the connecting arc plate 19. The gear 5 20 meshes with the teeth. One of the worms 21 meshes with one of the gears 3 12, and the other worm 21 meshes with one of the gears 4 14. A push rod 22 is fixedly connected to the top side of the right end of the connecting arc plate 19. The front end of the push rod 22 is rotatably connected to a connecting rod 23. The middle end of the connecting rod 23 is rotatably connected to the left top end of the shell 10. A limiting groove is provided on the right side of the front end of the shell 10, and the left side of the top end of the tightening sleeve 24 is slidably connected to the inside of the limiting groove.

[0045] Specifically, when tightening sleeve 24 moves downward, it slides in the slide groove on the front side of housing 10 and compresses the return spring. When the top of tightening sleeve 24 is no longer under pressure, the compressed return spring pushes tightening sleeve 24 back to its original position. Sliding rod 17 is used to limit the connecting arc plate 19, preventing it from rotating under the drive of screw rod 18, thereby stabilizing the displacement of connecting arc plate 19. The screw 18 is driven by the motor to rotate to drive the connecting arc plate 19 connected to it, so that the teeth on the connecting arc plate 19 mesh with the gear five 20 connected to the worm 21, so that the worms 21 at both ends mesh with the corresponding gear three 12 and gear four 14. The raised connecting arc plate 19 simultaneously drives the push rod 22 connected to the right end to rise, pushing the rear end of the connecting rod 23 upward, and rotates at the rear end of the connecting rod 23, so that the rear end of the connecting rod 23 is tilted and the front end is pressed down, so that the limiting groove on the right side of the front end contacts the connecting part on the left side of the top of the tightening sleeve 24, thereby pushing the tightening sleeve 24 to move downward, and can drive the tightening sleeve 24 used to tighten the lamp holder to descend while the connecting arc plate 19 drives the positioning buckle to close and start positioning work, so as to quickly put it on the positioned lamp holder, realize synchronous assembly process, thereby improving production coordination, assembly efficiency and assembly accuracy.
