Description

Technical Field

[0001] This invention belongs to the field of laser processing equipment technology, and specifically relates to a multi-angle laser processing equipment for lampshade production. Background Technology

[0002] Existing multi-angle laser processing equipment for lampshade production is mainly used to process lighting patterns on the outside of lampshades according to customers' personalized needs. It requires importing the design pattern into the laser cutting machine controller, and then using the CNC system to laser cut the lampshade to form a hollow lighting pattern. During the laser cutting process, the lampshade needs to be clamped and fixed to prevent it from shaking and affecting the processing quality. The lampshade is usually truncated cone-shaped, and the common clamping method is to clamp and fix it to the outer surface with jaws. However, the jaws may block the laser cutting path, requiring multiple adjustments, resulting in low processing efficiency. Alternatively, there is a method of fixing the lampshade by pressing it from the top, but this requires manual adjustment of the pressing position to match the reference of the CNC system, which is more cumbersome and less efficient. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-angle laser processing equipment for lampshade production, so as to solve the problem of low efficiency caused by the cumbersome operation of existing multi-angle laser processing equipment for lampshade production.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A multi-angle laser processing device for producing lampshades includes a base and a placement seat fixed on the base. A pressure frame for pressing the lampshade is slidably provided above the base, and a moving component is provided below the pressure frame. A laser generator is provided on the moving component.

[0006] Multiple columns are fixedly installed on the base, and a top frame is fixedly installed between the tops of the multiple columns. A slide is slidably provided below the top frame. A spring is fixedly connected between the top of the pressure frame and the bottom of the top frame. Two sliding grooves are symmetrically provided on the pressure frame. A positioning rod is slidably connected in each of the two sliding grooves. A first connecting rod is rotatably connected between each of the two positioning rods and the slide.

[0007] Preferably, two guide rods slide through the top frame, the bottom ends of the two guide rods are fixedly connected to the top of the pressure frame, and the spring is sleeved on the outside of the guide rods.

[0008] Preferably, a fixing plate is fixedly installed inside the top frame, and a second electric push rod is fixedly installed on the fixing plate. The telescopic end of the second electric push rod is fixedly connected to the slide.

[0009] Preferably, the slide groove has an I-shaped structure, and one end of the positioning rod abuts against both the upper and lower sides of the slide groove.

[0010] Preferably, the moving component includes a circular frame and a slide block slidably connected to the inner side of the moving frame. A mounting frame is horizontally slidably provided on one side of the slide block, and a rotating frame is rotatably connected to one end of the mounting frame. The laser generator is fixed inside the rotating frame.

[0011] Preferably, the movable frame is provided with an annular guide groove, and the slide block is slidably engaged in the annular guide groove.

[0012] Preferably, a first electric push rod is fixedly installed on the pressure frame, and the telescopic end of the first electric push rod is fixedly connected to the movable frame.

[0013] Preferably, a toothed ring is fixedly installed on the inner side of the movable frame, and a gear is rotatably provided on the slide block, the gear being meshed with the toothed ring.

[0014] Preferably, a third electric push rod is fixedly installed on one side of the slide block, and the telescopic end of the third electric push rod is fixedly connected to the mounting bracket.

[0015] Preferably, a slider is slidably connected to one side of the mounting frame, a lead screw that screws through the slider is rotatably provided inside the mounting frame, and a second connecting rod is rotatably connected between the slider and one side of the rotating frame.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] (1) The present invention is provided with a pressure frame, a spring, a slide, a first connecting rod and a positioning rod. When the lamp cover is pressed and fixed, the slide moves down, causing the first connecting rod and the positioning rod to move down. At the same time, the spring force causes the pressure frame to move down. After the pressure frame touches the top of the lamp cover, the slide continues to move down. At this time, the pressure frame cannot move down, so the slide moves the two positioning rods to the sides along the two slide grooves through the two first connecting rods. After the two positioning rods touch the inner top of the lamp cover, the slide continues to move down, causing the positioning rods to push the pressure frame down to press and fix the lamp cover. The two symmetrically arranged positioning rods ensure that the axis of the lamp cover is always located in the middle position of the two positioning rods, eliminating the need for manual positioning and calibration of the lamp cover, which is highly efficient.

[0018] (2) Before the pressure frame touches the top of the lampshade, the spring force of the present invention causes the pressure frame to be subjected to a force away from the top frame, so that the pressure frame and the slide are always far apart from each other. Thus, the first connecting rod makes the two positioning rods always located in the middle and close to each other, so that the distance between the two positioning rods is small. This makes it easier for the two positioning rods to automatically extend into the inside of the lampshade when the pressure frame moves down, which facilitates the automatic positioning of the lampshade and improves efficiency.

[0019] (3) The present invention only needs to push out the telescopic end through the second electric push rod to complete the positioning and clamping of the lamp cover. The top clamping and fixing does not affect the laser cutting processing on the side of the lamp cover. It does not require multiple adjustments to the clamping position of the lamp cover. The operation is simple and efficient.

[0020] (4) The present invention uses the meshing transmission of gears and gear rings to make the slide move in the annular guide groove of the moving frame, thereby driving the laser generator to move around the outside of the lampshade through the mounting frame and rotating frame, so that the laser generator can point to any position outside the lampshade. At the same time, the sliding of the slider along the lead screw causes the second connecting rod to push the rotating frame to rotate, thereby driving the laser generator to rotate around the rotation axis of the rotating frame, so that the laser generator can face the frustum-shaped lampshade with different inclinations, thereby realizing multi-angle laser processing and ensuring the flatness and beauty of the laser cutting.

[0021] (5) The present invention allows the laser generator to be moved to any processing position outside the lampshade by lifting the mobile frame and moving the mounting frame horizontally, and can be applied to lampshades of different specifications. In addition, automatic and continuous laser processing operation can be achieved through the control of the control system, which has high efficiency. Attached Figure Description

It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein.

[0032] Please see Figures 1-8 As shown, the present invention provides the following technical solution:

[0033] A multi-angle laser processing equipment for lampshade production includes a base 1 and a placement seat 4 fixed on the base 1. A pressure frame 3 for pressing the lampshade is slidably provided above the base 1. A moving component is provided below the pressure frame 3. A laser generator 5 is provided on the moving component.

[0034] Multiple columns 11 are fixedly installed on the base 1. A top frame 12 is fixedly installed between the tops of the multiple columns 11. A slide 36 is slidably provided below the top frame 12. A spring 33 is fixedly connected between the top of the pressure frame 3 and the bottom of the top frame 12. Two sliding grooves 37 are symmetrically provided on the pressure frame 3. A positioning rod 35 is slidably connected in each of the two sliding grooves 37. A first connecting rod 34 is rotatably connected between the two positioning rods 35 and the slide 36.

[0035] Two guide rods 32 slide through the top frame 12, and the bottom ends of the two guide rods 32 are fixedly connected to the top of the pressure frame 3, and springs 33 are sleeved on the outside of the guide rods 32;

[0036] A fixing plate 13 is fixedly installed inside the top frame 12, and a second electric push rod 31 is fixedly installed on the fixing plate 13. The telescopic end of the second electric push rod 31 is fixedly connected to the slide 36.

[0037] The slide groove 37 has an I-shaped structure, and one end of the positioning rod 35 abuts against both the upper and lower sides of the slide groove 37.

[0038] Based on the above-disclosed structure, when performing laser processing on the lampshade:

[0039] First, place the lampshade to be processed on the placement seat 4, and position the two positioning rods 35 directly above the frustum-shaped lampshade. Then, activate the second electric push rod 31 to extend the telescopic end, causing the slide 36 to move downward. This causes the two first connecting rods 34 to drive the two positioning rods 35 downward, so that the two positioning rods 35 gradually extend into the lampshade from the top. At the same time, the elastic force of the two springs 33 pushes the pressure frame 3 downward, causing the two guide rods 32 to slide within the top frame 12. This causes the pressure frame 3 to move vertically downward along the extension direction of the guide rods 32 until the bottom of the pressure frame 3 contacts the top of the lampshade. At this time, the two positioning rods 35 are located inside the top of the lampshade.

[0040] Then, the second electric push rod 31 is pushed out of the telescopic end, causing the slide 36 to continue to move downward. At this time, the bottom of the pressure frame 3 is in contact with the top of the lampshade, preventing the pressure frame 3 from moving downward. This causes the slide 36 to drive one end of the two first connecting rods 34 to move downward, causing the other end of the two first connecting rods 34 to push the two positioning rods 35 to move to both sides along the two sliding grooves 37 on the pressure frame 3. This causes the two positioning rods 35 to move to both sides and contact the inner side of the top of the lampshade. Since the two positioning rods 35 are symmetrically arranged, when both positioning rods 35 are in contact with the inner side of the lampshade, the central axis of the lampshade is located at the center of the two positioning rods 35. This is used to position the lampshade so that it matches the reference of the CNC system, making it easy to directly perform CNC machining on the lampshade.

[0041] Then, the second electric push rod 31 is pushed out of the telescopic end, causing the slide 36 to continue to move downward. At this time, the two positioning rods 35 abut against the inner side of the top of the lamp cover, preventing the two positioning rods 35 from moving to the sides. Thus, the slide 36, through the two first connecting rods 34, causes the two positioning rods 35 to push the pressure frame 3 downward to press the lamp cover using the I-shaped structure of the slide groove 37, thereby achieving the pressing and fixing of the lamp cover.

[0042] Finally, the moving component drives the laser generator 5 to move outside the lampshade, so that the laser generator 5 performs laser cutting on the lampshade, forming the desired lighting pattern on the outside of the lampshade.

[0043] Furthermore, before the pressure frame 3 contacts the top of the lampshade, the elastic force of the spring 33 ensures that the pressure frame 3 is always subjected to a downward thrust away from the top frame 12, causing the pressure frame 3 to exert a downward force on the two positioning rods 35. This, through the two first connecting rods 34, ensures that there is always a force between the pressure frame 3 and the slide 36 to keep them away from each other. Thus, through the first connecting rods 34, the two positioning rods 35 are always located close to each other in the middle of the pressure frame 3 along the slide groove 37. This results in a smaller distance between the two positioning rods 35, making it easier for the two positioning rods 35 to automatically extend into the inside of the lampshade when the pressure frame 3 moves down. This facilitates subsequent automatic positioning operations of the lampshade and improves efficiency.

[0044] Preferably, the clamping and fixing process of the lampshade can be completed simply by pushing out the telescopic end through the second electric push rod 31. The operation is simple and efficient, which greatly reduces the manufacturing cost of the equipment. Moreover, the top clamping and fixing method does not affect the laser cutting processing operation on the side of the lampshade, and there is no need to adjust the clamping position of the lampshade multiple times, which further improves the processing efficiency.

[0045] Regarding the moving component, the following structure is preferred:

[0046] The moving component includes a ring-shaped moving frame 2 and a slide block 22 slidably connected to the inner side of the moving frame 2. A mounting frame 52 is horizontally slidably provided on one side of the slide block 22. A rotating frame 51 is rotatably connected to one end of the mounting frame 52. The laser generator 5 is fixed inside the rotating frame 51.

[0047] The movable frame 2 is provided with an annular guide groove 21, and the slide block 22 is slidably fitted in the annular guide groove 21;

[0048] A first electric push rod 25 is fixedly installed on the pressure frame 3, and the telescopic end of the first electric push rod 25 is fixedly connected to the movable frame 2;

[0049] A toothed ring 23 is fixedly installed on the inner side of the movable frame 2, and a gear 24 is rotatably mounted on the slide 22. The gear 24 meshes with the toothed ring 23.

[0050] A third electric push rod 53 is fixedly installed on one side of the slide block 22, and the telescopic end of the third electric push rod 53 is fixedly connected to the mounting bracket 52.

[0051] A slider 56 is slidably connected to one side of the mounting bracket 52. A screw 54 that screws through the slider 56 is rotatably provided inside the mounting bracket 52. A second connecting rod 55 is rotatably connected between the slider 56 and one side of the rotating frame 51.

[0052] As can be seen from the above, the lampshade is positioned by two positioning rods 35, ensuring that the axis of the lampshade is always in the middle position of the two positioning rods 35. Therefore, the vertical axis of the moving frame 2 coincides with the central axis of the lampshade. When the laser generator 5 processes the lampshade, the first electric push rod 25 extends its telescopic end, causing the moving frame 2 to gradually move from the top of the lampshade toward the bottom of the lampshade. This, in turn, drives the slide block 22 to gradually move from the top of the lampshade toward the bottom of the lampshade through the annular guide groove 21. Consequently, the mounting frame 52 and the rotating frame 51 drive the laser generator 5 to gradually move from the top of the lampshade toward the bottom of the lampshade, thus realizing the downward movement of the laser generator. Conversely, the first electric push rod 25 retracts its telescopic end, realizing the upward movement of the laser generator 5.

[0053] Furthermore, when the third electric push rod 53 extends its telescopic end, the mounting bracket 52 drives the rotating bracket 51 to move toward the lampshade, thereby driving the laser generator 5 to move toward the lampshade; conversely, when the third electric push rod 53 retracts its telescopic end, the laser generator 5 moves toward the lampshade.

[0054] In addition, when the gear 24 is driven to rotate by an external motor, the meshing transmission between the gear 24 and the gear ring 23 causes the gear 24 to roll inside the gear ring 23, thereby causing the gear 24 to drive the slide 22 to move along the annular guide groove 21 inside the moving frame 2. Then, the laser generator 5 is driven to move along the annular guide groove 21 through the mounting frame 52 and the rotating frame 51. Since the vertical axis of the moving frame 2 coincides with the central axis of the lampshade, the laser generator 5 can rotate around the outside of the lampshade to any position outside the lampshade.

[0055] Furthermore, another external motor drives the lead screw 54 to rotate, causing the slider 56 to move along the lead screw 54 towards the lampshade. This causes one side of the slider 56 to move one end of the second connecting rod 55, which in turn pushes the rotating frame 51 to rotate downward at the end of the mounting frame 52, thereby causing the laser generator 5 to rotate downward. Conversely, driving the lead screw 54 to rotate causes the slider 56 to move along the lead screw 54 away from the lampshade, causing the laser generator 5 to rotate upward. This allows adjustment of the laser outlet angle of the laser generator 5, thereby adjusting the angle between it and the outer wall of the lampshade. This allows the laser outlet of the laser generator 5 to face the frustum-shaped lampshade with different inclinations, thus achieving multi-angle laser processing and ensuring a smooth and aesthetically pleasing laser-cut surface.

[0056] In summary, by uniformly controlling the extension and retraction of the first electric push rod 21, the extension and retraction of the third electric push rod 53, the drive rotation of the gear 24, and the drive rotation of the lead screw 54 through the control system, the laser generator 5 can be moved to any position outside the lampshade. Furthermore, at any processing position outside the lampshade, the laser generator 5 can ensure that the laser outlet of the laser generator 5 faces the outer wall of the lampshade. This enables continuous laser processing of the lampshade, greatly improving processing efficiency and achieving high processing quality. In addition, it can be applied to lampshades of different specifications, increasing its practicality.
