Description

Technical Field

[0001] This utility model relates to the field of drilling technology for LED lamp processing, and in particular to a drilling device for LED lamp processing. Background Technology

[0002] LED lighting fixtures are a general term for LED lamps, which refer to devices that can transmit light, distribute and change the light distribution of LED light sources. In the manufacturing process of lamps, drilling devices are required to perform corresponding drilling operations.

[0003] A drilling device for LED lighting processing, with publication number CN220971629U, uses a clamping unit. When the dual-axis hydraulic cylinder retracts, it drives two blocks closer together. With the cooperation of the round rod and connecting block, the two blocks can drive the corresponding clamping shells to move closer together. During the drilling process, the generated debris is blocked by the two clamping shells, preventing debris from flying everywhere and accidentally injuring the workers, thus improving the safety of drilling.

[0004] In their daily work, the inventors discovered that the drilling device for LED lamp processing uses a "motor + circular gear + rack" lifting structure for its lifting unit. This structure has two core problems: First, the inherent clearance during gear meshing causes the drill bit to easily deviate during lifting, resulting in hole position deviations exceeding the allowable error range for LED lamp assembly. This fails to meet the requirements for precise subsequent lamp assembly, ultimately leading to a high scrap rate. Second, the meshing transmission method of gears and racks causes significant wear on the tooth surfaces. After long-term use, the tooth surfaces are prone to noticeable wear, requiring frequent replacement of the gear and rack assembly. This not only increases equipment replacement costs but also leads to high downtime for maintenance, severely impacting production continuity and making it difficult to meet the high-efficiency requirements of industrialized mass production. Utility Model Content

[0005] The purpose of this utility model is to solve the problems mentioned above in the background art by proposing a drilling device for LED lamp processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a drilling device for LED lamp processing, comprising a workbench, a collection box placed on the surface of the workbench, a lifting device provided on the surface of the workbench, the lifting device comprising an L-shaped bracket fixedly installed on the surface of the workbench, a U-shaped rod fixedly installed on the inner wall surface of the vertical end of the L-shaped bracket, and a slide plate slidably connected to the outer wall surface of the U-shaped rod.

[0007] Preferably, a connecting plate is fixedly installed on one side surface of the slide bar, a U-shaped support frame is fixedly installed on the end of the connecting plate away from the slide bar, and discs are fixedly installed on the bottom surfaces of the vertical ends on both sides of the U-shaped support frame.

[0008] Preferably, a motor is fixedly mounted on the surface of the disc, and a drill bit is fixedly mounted on the output end of the motor via a coupling.

[0009] Preferably, a first PLC controller is fixedly installed on the surface of the horizontal end of the U-shaped support frame, and a cylinder is fixedly installed on the surface of the top horizontal end of the L-shaped bracket. The cylinder and the motor are electrically connected to the first PLC controller.

[0010] The aforementioned components achieve the following effects: by using an L-shaped bracket as a base, and providing precise guidance for the slide plate through a U-shaped rod, coupled with cylinder drive, the meshing gap problem of the traditional "motor + gear + toothed plate" structure is avoided. The slide plate slides along the U-shaped rod without deviation, which can drive the drill bit to rise and fall smoothly, effectively preventing the drill bit from deviating in position during drilling, ensuring that the hole position accuracy meets the assembly requirements of LED lamps, reducing scrap due to insufficient accuracy, and improving the finished product qualification rate.

[0011] Preferably, the surface of the workbench is provided with an adjustment device, the adjustment device including a vertical plate fixedly installed on the surface of the workbench, a slide rod fixedly installed on the surface of the vertical plate, a vertical plate fixedly installed at the end of the slide rod away from the vertical plate, a movable plate slidably connected to the outer wall surface of the slide rod, and a first electric telescopic rod fixedly installed on the surface of the vertical plate, the output end of the first electric telescopic rod being fixedly connected to the movable plate.

[0012] Preferably, a round rod is fixedly installed on the surface of the movable plate, a sliding seat is slidably connected to the outer wall surface of the round rod, an anti-detachment plate is fixedly installed at the end of the round rod away from the movable plate, an extension plate is fixedly installed on one side surface of the movable plate, a second electric telescopic rod is fixedly installed on the surface of the extension plate, an extension plate is fixedly installed on one side surface of the sliding seat, the output end of the second electric telescopic rod is fixedly connected to the extension plate, a second PLC controller is fixedly installed on one side surface of the workbench, and both the first electric telescopic rod and the second electric telescopic rod are electrically connected to the second PLC controller.

[0013] Preferably, two L-shaped rods are fixedly installed on the surface of the sliding seat. A first arc-shaped clamping ring is fixedly installed at the end of the two L-shaped rods away from the sliding seat. A crossbar is fixedly installed on the surface of the extension portion on both sides of the first arc-shaped clamping ring. A second arc-shaped clamping ring is slidably connected between the two crossbars. A circular plate is fixedly installed on the surface of the end of the crossbar away from the first arc-shaped clamping ring. A spring is fixedly installed between the circular plate and the extension portion of the second arc-shaped clamping ring.

[0014] Preferably, a positioning plate is fixedly installed on one side surface of the extension portion of the first arc-shaped clamping ring, and a bolt is threadedly connected to the surface of the positioning plate. A fixing plate is fixedly installed on one side surface of the extension portion of the second arc-shaped clamping ring, and a threaded hole matching the bolt is opened on the surface of the fixing plate.

[0015] The effect achieved by the above components is as follows: through the linkage of the first and second electric telescopic rods, and in conjunction with the second PLC controller, the position of the lamp can be automatically adjusted. Only the hole coordinates need to be input, and the lamp can be moved in the horizontal and vertical directions by the electric telescopic rods, which can quickly complete the multi-hole positioning, greatly reduce the manual operation time, and is especially suitable for LED lamps that need to be processed with multiple holes, significantly improving processing efficiency.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting up a lifting device, an L-shaped bracket is used as the base, and a U-shaped rod provides precise guidance for the slide plate. With the help of a cylinder drive, the meshing gap problem of the traditional "motor + gear + toothed plate" structure is avoided. The slide plate slides along the U-shaped rod without deviation, which can drive the drill bit to rise and fall smoothly. This effectively prevents the drill bit from deviating in position during the drilling process, ensures that the hole position accuracy meets the assembly requirements of LED lamps, reduces scrap due to insufficient accuracy, and improves the finished product qualification rate.

A circular plate 317 is fixedly mounted between the extensions of the circular plate 317 and the second arc-shaped clamping ring 316. The device includes a spring 318, a positioning plate 321 fixedly mounted on one side surface of the extension of the first arc-shaped clamping ring 314, a bolt 322 threadedly connected to the surface of the positioning plate 321, a fixing plate 319 fixedly mounted on one side surface of the extension of the second arc-shaped clamping ring 316, and a threaded hole 320 matching the bolt 322 on the surface of the fixing plate 319. The first electric telescopic rod 305 is model XTL100 with a thrust of 500N, the second electric telescopic rod 310 is model XTL60 with a thrust of 300N, and the second PLC controller 312 is model S7-200 SMART with a position preset function. The inner layer of the first arc-shaped clamping ring 314 and the second arc-shaped clamping ring 316 is medical silicone, and the outer layer is 304 stainless steel. The spring 318 is made of stainless steel with an elastic coefficient of 3N / mm.

[0022] Working principle: When using this device, the operator first pulls the second arc-shaped clamping ring 316 by hand according to the thickness of the LED lamp to be processed. The second arc-shaped clamping ring 316 slides along the crossbar 315 away from the first arc-shaped clamping ring 314, during which the spring 318 between the circular plate 317 and the second arc-shaped clamping ring 316 is compressed. Then, the LED lamp is placed stably inside the first arc-shaped clamping ring 314, aligning the edge of the lamp with the baseline of the first arc-shaped clamping ring 314, ensuring that the area to be drilled is within the projection range directly below the drill bit 208. Then, the second arc-shaped clamping ring 316 is slowly released. The spring 318 pushes the second arc-shaped clamping ring 316 back to its original position with its own rebound force, so that the first arc-shaped clamping ring 314 and the first arc-shaped clamping ring 316 are aligned. The silicone inner layer of the two arc-shaped clamping rings 316 tightly adheres to the surface of the lamp, initially clamping the lamp. Finally, the bolts 322 on the surface of the positioning plate 321 are tightened using a tool: the bolts 322 are slowly screwed into the threaded holes 320 of the fixing plate 319 until the resistance is uniform, further locking the positions of the first arc-shaped clamping rings 314 and the second arc-shaped clamping rings 316 to prevent the lamp from loosening during drilling. After the lamp is fixed, the drilling parameters are set on the touch screen of the first PLC controller 209: the motor speed 207 is input according to the lamp material, and the lifting stroke of the cylinder 210 is set according to the required drilling depth, controlled by a magnetic ring limit switch to avoid piercing the lamp or insufficient depth. Simultaneously, the hole coordinates of the lamp are input on the second PLC controller 312 according to the lamp design drawings. Input the X-axis and Y-axis position parameters to be drilled. The system automatically calculates the moving distance of the first electric telescopic rod 305 and the second electric telescopic rod 310 to prepare for precise positioning. After the parameters are set, click the "Drill Start" button on the first PLC controller 209: the motor 207 is powered on first and starts, driving the drill bit 208 to rotate at high speed through the coupling. After the drill bit 208 speed stabilizes, the cylinder 210 is powered on: the piston rod pushes the slide plate 203 to slide slowly downward along the U-shaped rod 202 on the inner wall of the L-shaped bracket 201. The U-shaped rod 202 ensures that the slide plate 203 moves without deviation. When the slide plate 203 moves downward, it drives the U-shaped support frame 205 to descend synchronously through the connecting plate 204. The U-shaped support frame 205 then drives the disc 20 6. The motor 207 and the rotating drill bit 208 move downwards. When the drill bit 208 contacts the surface of the lamp, the drilling operation begins. The cylinder 210 continuously provides a stable thrust to ensure that the drill bit 208 cuts into the lamp at a uniform speed. The debris generated during drilling falls into the collection box 4 below under the action of gravity. When the cylinder 210 descends to the preset stroke, the magnetic ring limit switch of the cylinder 210 triggers a signal. The first PLC controller 209 controls the cylinder 210 to stop descending and rise in the opposite direction, driving the drill bit 208 away from the lamp to complete the drilling operation of a single hole. If the LED lamp needs to be processed with multiple holes, first click "Position Adjustment" on the second PLC controller 312: the first electric telescopic rod 305 is powered on and starts, pushing the moving plate 304 to slide along the slide rod 302.The lamp's position is adjusted along the X-axis. Once the lamp has moved to the next hole position coordinate, the second PLC controller 312 displays "Positioning Complete." The "Drilling Start" step is repeated until all preset holes are machined. After all holes are machined, the power to the first PLC controller 209 and the second PLC controller 312 is turned off. Then, bolt 322 is loosened, and the second arc-shaped clamping ring 316 is pulled to remove the machined LED lamp. The drilling quality is checked; the holes are free of offset and burrs. Once qualified, the lamp is placed in the finished product box. Then, the debris collected in the collection box 4 is emptied.
