Description

Technical Field

[0001] The present invention belongs to the technical field of polishing, and particularly relates to a polishing processing device for the surface of a spherical LED lamp. Background Art

[0002] An LED lamp is an energy-saving lamp mainly made of light-emitting diodes. Its basic structure is a piece of electro-luminescent semiconductor material placed on a shelf with leads, and then sealed with epoxy resin around to protect the internal core wires. It is mainly used for outdoor lighting and decoration. In particular, spherical LED lamps can even be used to make some spherical ornaments by emitting light, greatly enriching people's daily life. Spherical LED lamps generally do not have external pins, but are powered by opening holes on the surface and connecting an external power supply (power plug). The surface of spherical LED lamps generally needs to be polished to ensure its surface is smooth and enhance its lighting and display effects. In the prior art, a mechanical clamping structure is generally used. First, the spherical LED lamp is pressed, and then it is driven to rotate so that its surface abuts against the polishing piece, and polishing is completed through sliding friction. However, this conventional clamping and driving method not only easily damages the surface of the spherical LED lamp, but also causes polishing dead corners. Moreover, when polishing the dead corner position for the second time, it will cause deviation from the first polishing, resulting in uneven polishing degree of the entire polished surface and affecting the final yield. Summary of the Invention

[0003] The purpose of the present invention is to provide a polishing processing device for the surface of a spherical LED lamp to solve the problems raised in the above background art.

[0004] To achieve the above object, the present invention provides the following technical solution: A polishing processing device for the surface of a spherical LED lamp, including a polishing box, a bracket, and a telescopic rod. The telescopic end of the telescopic rod is installed with a mounting frame. Inside the mounting frame, a support column and a ball screw are respectively installed. A slider is threadedly installed on the outer surface of the ball screw. The bottom of the slider is fixedly installed with a polishing block. At the bottom of the inner wall of the polishing box, a support cylinder is fixedly installed. Inside the support cylinder, a second spring and a support rod are movably sleeved. The top of the support rod is fixedly connected to a first fixing block. Inside the first fixing block, a first steel ball is movably installed. On the inner wall of the polishing box, multiple groups of fixing columns are fixedly installed at equal intervals in the circumferential direction. The top of the fixing column is fixedly connected to a second fixing block. Inside the second fixing block, a second steel ball is movably installed. Between the outer surfaces of the first steel ball and the second steel ball, a spherical LED lamp is placed by means of rotational support. The bottom of the polishing block is adaptively abutted against the top of the spherical LED lamp. On the back of the mounting frame, a placement frame is fixedly installed. The top of the placement frame is fixedly connected to a communication pipe. Inside the placement frame, an extension frame is hermetically clamped. On the inner wall of the extension frame, two groups of clamping blocks are fixedly connected. Between the top of the inner wall of the placement frame and the extension frame, a first spring is elastically connected. Both the first steel ball and the second steel ball can rotate freely without dead angles.

[0005] As a preferred solution of the present invention, the bracket is fixedly installed on the top of the polishing box, the telescopic rod is installed on the top of the bracket, the slider is slidably installed on the outer surface of the support column, and a through groove is opened at the bottom of the front surface of the slider.

[0006] As a preferred solution of the present invention, chamfers are provided on both the front and rear sides of the inner ring surface of the polishing block, and the chamfer angle is 45°.

[0007] As a preferred solution of the present invention, the second spring is located at the bottom of the inner cavity of the support cylinder and provides elastic support for the support rod, so that the first steel ball can keep abutting against the bottom of the spherical LED lamp.

[0008] As a preferred solution of the present invention, the cross-sectional shape of the polishing block is semi-circular ring-shaped, and the polishing block can move in the front-rear direction under the drive of the ball screw.

[0009] As a preferred solution of the present invention, a buffer pad is glued to the bottom of the extension frame, and the buffer pad is made of a rubber block.

[0010] As a preferred solution of the present invention, the top of the inner wall of the clamping block is inclined, and an air passage with a wider top and a narrower bottom is formed between the two groups of clamping blocks.

[0011] As a preferred embodiment of the present invention, an exhaust port is provided at the bottom of the polishing box. The downward exhaust passage of the extension frame is located inside the vertical tangent of the spherical LED lamp, and the exhaust port is vertically opposite to the bottom opening of the extension frame.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The device is redesigned. The rotatable steel ball 1 and steel ball 2 are used to rotatably support the spherical LED lamp. The telescopic rod drives the polishing block to press downward and abut against the top of the spherical LED lamp, providing limit and fixation for the spherical LED lamp. By setting a placement frame and a connecting pipe externally connected to an air compressor, a continuous high-pressure air flow is generated in the inner cavity of the placement frame. When the high-pressure air flow acts vertically downward on the right side of the outer surface of the spherical LED lamp under the guidance of the placement frame and the extension frame, it will drive the entire spherical LED lamp to rotate clockwise. At the same time, the spherical LED lamp synchronously performs a full-round polishing operation through sliding friction with the inner ring surface of the polishing block, thus solving the problem of polishing dead corners under traditional mechanical clamping.

[0014] 2. Then, the front and rear sides of the inner ring surface of the polishing block are chamfered at 45°. The chamfered part of the inner ring surface of the polishing block can adapt to spherical LED lamps of different sizes. When facing spherical LED lamps of different sizes, the radius of the inner ring surface of the polishing block needs to be changed to adapt. At this time, by setting a ball screw to drive the slider and the polishing block to move forward or backward, the chamfered inclined surface of the inner ring surface of the polishing block moves directly above the spherical LED lamp, and the position of the polishing block is adjusted according to the size of the spherical LED lamp, so as to perfectly adapt to the outer surface of the spherical LED lamp, significantly enhancing the adaptability of the device.

[0015] 3. The device also narrows the bottom opening of the extension frame through a clamping block to increase the flow rate of the compressed air flow from the connecting pipe and the air compressor. When the spherical LED lamp driven by the compressed air rotates during the polishing operation, the high-pressure air flow continuously flushing downward from the bottom opening of the extension frame will "blow" the polished surface of the spherical LED lamp in all directions. On the surface of the spherical LED lamp, all impurities generated by polishing can be removed wherever the high-pressure air flow reaches. And because an exhaust port is provided at the bottom of the polishing box, the impurities carried away by the high-pressure air flow can be discharged from the exhaust port, realizing the high-efficiency surface cleaning function of the device.

Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] As Figures 1 to 8As shown in the figure, an embodiment of the present invention provides a polishing processing device for the surface of a spherical LED lamp, including a polishing box 1, a bracket 2, and a telescopic rod 3. An installation frame 4 is installed at the telescopic end of the telescopic rod 3. Inside the installation frame 4, a support column 5 and a ball screw 6 are respectively installed. A slider 7 is threadedly installed on the outer surface of the ball screw 6. A polishing block 9 is fixedly installed at the bottom of the slider 7. At the bottom of the inner wall of the polishing box 1, a support cylinder 18 is fixedly installed. Inside the support cylinder 18, a second spring 19 and a support rod 20 are movably sleeved. The top end of the support rod 20 is fixedly connected to a first fixing block 21. Inside the first fixing block 21, a first steel ball 22 is movably installed. On the inner wall of the polishing box 1, multiple groups of fixing columns 23 are fixedly installed at equal intervals in the circumferential direction. The top end of the fixing column 23 is fixedly connected to a second fixing block 24. Inside the second fixing block 24, a second steel ball 25 is movably installed. Between the outer surfaces of the first steel ball 22 and the second steel ball 25, a spherical LED lamp 10 is placed in a rotation-supported manner. The bottom of the polishing block 9 is adaptively abutted against the top of the spherical LED lamp 10. On the back of the installation frame 4, a placement frame 11 is fixedly installed. At the top of the placement frame 11, a connecting pipe 12 is fixedly connected. The connecting pipe 12 is used to connect an air compressor. Inside the placement frame 11, an extension frame 13 is hermetically clamped. On the inner wall of the extension frame 13, two groups of clamping blocks 16 are fixedly connected. Between the top of the inner wall of the placement frame 11 and the extension frame 13, a first spring 15 is elastically connected. Both the first steel ball 22 and the second steel ball 25 can rotate freely without dead angles;

[0027] This device has been redesigned. The spherical LED lamp 10 is rotationally supported by the freely rotatable first steel ball 22 and second steel ball 25. The telescopic rod 3 drives the polishing block 9 to press downward and abut against the top of the spherical LED lamp 10, providing limit and fixation for the spherical LED lamp 10. By setting up a placement frame 11 and a connecting pipe 12 externally connected to an air compressor, a continuous high-pressure air flow is generated in the inner cavity of the placement frame 11. When the high-pressure air flow acts vertically downward on the right side of the outer surface of the spherical LED lamp 10 under the guidance of the placement frame 11 and the extension frame 13, it will drive the entire spherical LED lamp 10 to rotate clockwise. At the same time, the spherical LED lamp 10 synchronously performs a full-range polishing operation through sliding friction with the inner ring surface of the polishing block 9, thus solving the problem of polishing dead angles under traditional mechanical clamping.

[0028] Then, the device also chamfers the front and rear sides of the inner ring surface of the polishing block 9 at an angle of 45°, so that the chamfered part of the inner ring surface of the polishing block 9 can adapt to spherical LED lamps 10 of different sizes. When facing spherical LED lamps 10 of different sizes, the radius of the inner ring surface of the polishing block 9 needs to change to adapt. At this time, by setting up a ball screw 6 to drive the slider 7 and the polishing block 9 to move forward or backward, the chamfered inclined surface of the inner ring surface of the polishing block 9 moves directly above the spherical LED lamp 10, and the position of the polishing block 9 is adjusted according to the size of the spherical LED lamp 10, so as to perfectly adapt to the outer surface of the spherical LED lamp 10, significantly enhancing the adaptability of the device.

[0029] Among them, the bracket 2 is fixedly installed on the top of the polishing box 1, the telescopic rod 3 is installed on the top of the bracket 2, the slider 7 is slidably installed on the outer surface of the support column 5, and a through groove 8 is opened at the bottom of the front surface of the slider 7;

[0030] The slider 7 is slidably installed on the outer surface of the support column 5, and is driven by the ball screw 6 to move back and forth along the outer surface of the support column 5, so that the inner ring surface of the polishing block 9 can be adjusted in position according to the size requirements of the spherical LED lamp 10. The through groove 8 helps to strengthen the air circulation on both sides of the polishing block 9, so that dust and other impurities generated when the spherical LED lamp 10 is polished can move downward through the through groove 8 to near the exhaust port 17.

[0031] Among them, chamfers are provided on both the front and rear sides of the inner ring surface of the polishing block 9, and the chamfer angle is 45°;

[0032] The function of the chamfer on the inner ring surface of the polishing block 9 is that when the size of the spherical LED lamp 10 increases, the ball screw 6 can be started to drive the polishing block 9 to move forward or backward, so that the inclined surface where the chamfer of the inner ring surface of the polishing block 9 is located is adapted to abut against the outer surface of the spherical LED lamp 10, so as to adapt to the outer surface of the spherical LED lamp 10 for polishing work.

[0033] Among them, the second spring 19 is located at the bottom of the inner cavity of the support cylinder 18 and provides elastic support for the support rod 20, so that the first steel ball 22 can keep abutting against the bottom of the spherical LED lamp 10;

[0034] The second spring 19, the support rod 20, the first fixing block 21 and the first steel ball 22 are jointly responsible for providing elastic support for spherical LED lamps 10 of different sizes. When the size of the spherical LED lamp 10 changes, the height of the bottom of the spherical LED lamp 10 will surely change. At this time, the second spring 19 elastically supports the support rod 20 upward, thus providing another elastic rotational support guarantee for the spherical LED lamp 10.

[0035] Among them, the cross-sectional shape of the polishing block 9 is a semi-annular ring, and the polishing block 9 can move in the front-back direction under the drive of the ball screw 6;

[0036] The semi-annular ring design of the polishing block 9 enables its interior to always be adapted to abut against the outer surface of the polishing block 9. Coupled with the movement of the polishing block 9 in the front-back direction, it can perfectly adapt to the polishing work of spherical LED lamps 10 of different sizes.

[0037] Among them, a buffer pad 14 is adhesively bonded to the bottom of the extension frame 13, and the buffer pad 14 is made of a rubber block;

[0038] Under the action of high-pressure air flow, the extension frame 13 can move downward by a certain distance. At this time, the buffer pad 14 can provide buffer protection for the bottom opening of the extension frame 13, avoiding rigid damage when the bottom of the extension frame 13 touches the spherical LED lamp 10.

[0039] The device also narrows the bottom opening of the extension frame 13 through the clamping block 16 to increase the flow rate of the compressed air from the connecting pipe 12 and the air compressor. When the spherical LED lamp 10 driven by the compressed air to rotate is performing polishing work, the high-pressure air flow continuously flushing downward from the bottom opening of the extension frame 13 will "blow" the polished surface of the spherical LED lamp 10 in all directions. On the surface of the spherical LED lamp 10, all impurities generated by polishing can be removed wherever the high-pressure air flow reaches. And because the bottom of the polishing box 1 is provided with an exhaust port 17, the impurities carried away by the high-pressure air flow can be discharged from the exhaust port 17, realizing the efficient surface cleaning function of the device.

[0040] Among them, the top of the inner wall of the clamping block 16 is inclined, and an air passage that is wider at the top and narrower at the bottom is formed between the two clamping blocks 16;

[0041] The clamping block 16 can increase the speed of the compressed air from the connecting pipe 12 through the narrowed air passage, improve the flow rate of the compressed air, and reduce the energy loss of the compressed air after leaving the extension frame 13.

[0042] Among them, the bottom of the polishing box 1 is provided with an exhaust port 17. The downward exhaust passage of the extension frame 13 is located inside the vertical tangent of the spherical LED lamp 10, and the exhaust port 17 is vertically opposite to the bottom opening of the extension frame 13;

[0043] The high-pressure air flow discharged downward from the extension frame 13 can drive the spherical LED lamp 10 to rotate and synchronously clean the impurities generated on the surface of the spherical LED lamp 10 due to polishing.

[0044] Working principle:

[0045] First, start the telescopic rod 3, drive the polishing block 9 to the highest position through the mounting frame 4 and the slider 7, connect the connecting pipe 12 to the air compressor and wait. Put the spherical LED lamp 10 into the device, make the outer surface of the spherical LED lamp 10 first contact the first steel ball 22, and press down the first fixing block 21 and the support rod 20, compress the second spring 19 until the outer surface of the spherical LED lamp 10 abuts and supports on the outer surface of the second steel ball 25 at the same time;

[0046] Then, start the telescopic rod 3, and drive the polishing block 9 and the placement frame 11 to move downward through the mounting frame 4 and the slider 7, so that the inner ring surface of the polishing block 9 is adaptively abutted against the outer surface of the spherical LED lamp 10. Close the telescopic rod 3. Then, the air compressor continuously inputs a large amount of high-pressure gas into the placement frame 11 through the connecting pipe 12. First, blow the extension frame 13 downward, and make the bottom opening of the extension frame 13 quickly approach the outer surface of the spherical LED lamp 10. Then, the flow rate of the high-pressure air increases as it passes through the inner cavity of the extension frame 13 and the gradually narrowing air passage between the two groups of clamping blocks 16, and acts downward on the surface of the spherical LED lamp 10, causing the spherical LED lamp 10 to rotate clockwise at a high speed around its own axis under the blowing of the air flow. During this process, the second steel ball 25 and the first steel ball 22 rotate synchronously and provide rotational support. At the same time, during the rotation of the spherical LED lamp 10, its surface has a sliding friction with the inner ring surface of the polishing block 9, and the entire surface of the spherical LED lamp 10 is polished;

[0047] Finally, when the polishing of the spherical LED lamp 10 is completed, just lift the polishing block 9 to the highest position, then the spherical LED lamp 10 can be taken out to complete the blanking. When facing spherical LED lamps 10 of different sizes, as Figure 4 shown, the second spring 19 provides elastic support for the support rod 20, so that the first steel ball 22 can always abut against the bottom of the spherical LED lamp 10. Start the ball screw 6, and drive the slider 7 and the polishing block 9 to move forward or backward, so that the inclined surface with a chamfer provided on the inner ring surface of the polishing block 9 is adaptively abutted against the outer surface of the spherical LED lamp 10. According to the size of the spherical LED lamp 10, adjust the front and rear positions of the polishing block 9, and make the inner ring surface of the polishing block 9 be able to be adaptively abutted against the spherical LED lamp 10.
