Description

Technical Field

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

[0002] LED lamp is an energy-saving lamp mainly made of light-emitting diodes. Its basic structure is a piece of electroluminescent semiconductor material, which is placed on a frame with leads and then sealed with epoxy resin on all sides to protect the internal core wire. It is mainly used for outdoor lighting and decoration. In particular, spherical LED lamps can even make some spherical decorations by emitting light, which greatly enriches people's daily life. Spherical LED lamps generally do not have external pins, but are powered by opening holes on the surface and connected to an external power supply (power plug). The surface of the spherical LED lamp generally needs to be polished to ensure its smooth surface and enhance its lighting and display effects. In the prior art, a mechanical clamping structure is generally used to first suppress the spherical LED lamp, and then drive it to rotate so that its surface abuts against the polishing piece, and polishing is completed by sliding friction. However, this conventional clamping and driving method is not only easy to damage the surface of the spherical LED lamp, but also causes polishing dead corners, and the second polishing of the dead corner position will cause deviations from the first polishing, resulting in different polishing degrees of the entire polished surface, affecting the final yield rate.

[0006] As a preferred solution of the present invention, both the front and rear sides of the inner annular surface of the polishing block are provided with chamfers, 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 tube and provides elastic support for the support rod, so that the first steel ball can maintain contact with 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 a semicircular ring, 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 block is designed to be inclined, and a gas passage that is wide at the top and narrow at the bottom is formed between the two groups of blocks.

[0011] As a preferred solution 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: 1. This device has been redesigned to support the spherical LED lamp with freely rotatable steel balls 1 and 2, and to drive the polishing block to press down and abut against the top of the spherical LED lamp through the telescopic rod, so as to provide the spherical LED lamp with position limitation and fixation. A placement frame and a connecting pipe are provided to connect the air compressor, and a continuous high-pressure airflow is generated in the inner cavity of the placement frame.

When the spherical LED lamp driven by the compressed air is being polished, the high-pressure airflow that continuously rushes 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, the high-pressure airflow can remove all impurities generated by polishing, and since an exhaust port is provided at the bottom of the polishing box, the impurities carried away by the high-pressure airflow can be discharged from the exhaust port, thereby realizing the efficient surface cleaning function of the device.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figures 1 to 8As shown, the 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, the telescopic end of the telescopic rod 3 is installed with a mounting frame 4, the interior of the mounting frame 4 is respectively installed with a pillar 5 and a ball screw 6, the outer surface of the ball screw 6 is threadedly installed with a slider 7, the bottom of the slider 7 is fixedly installed with a polishing block 9, the bottom of the inner wall of the polishing box 1 is fixedly installed with a support cylinder 18, the interior of the support cylinder 18 is movably sleeved with a spring 21 and a support rod 20, the top of the support rod 20 is fixedly connected with a fixed block 21, the interior of the fixed block 21 is movably installed with a steel ball 22, a plurality of groups of fixed columns 23 are fixedly installed at equal intervals on the circumference of the inner wall of the polishing box 1, and the top of the fixed column 23 is fixedly installed with a plurality of fixed columns 23. The end is fixedly connected with a fixing block 24, and a steel ball 25 is movably installed inside the fixing block 24. A spherical LED lamp 10 is placed between the outer surfaces of the steel ball 12 and the steel ball 25 by means of rotational support. The bottom of the polishing block 9 is adapted to abut against the top of the spherical LED lamp 10. A placement frame 11 is fixedly installed on the back of the mounting frame 4. A connecting pipe 12 is fixedly connected to the top of the placement frame 11. The connecting pipe 12 is used to connect the air compressor. The internal sealing card of the placement frame 11 is connected with an extension frame 13. The inner wall of the extension frame 13 is fixedly connected with two groups of card blocks 16. A spring 15 is elastically connected between the top of the inner wall of the placement frame 11 and the extension frame 13. Both the steel ball 12 and the steel ball 25 can rotate freely without dead angles. The device has been redesigned to support the spherical LED lamp 10 with freely rotatable steel ball 1 22 and steel ball 2 25, and to drive the polishing block 9 to press down and abut against the top of the spherical LED lamp 10 through the telescopic rod 3, so as to provide positioning and fixation for the spherical LED lamp 10. A placement frame 11 and a connecting pipe 12 are provided to connect an air compressor, and a continuous high-pressure airflow is generated in the inner cavity of the placement frame 11. When the high-pressure airflow acts vertically downward to 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, the spherical LED lamp 10 is driven to rotate clockwise. At the same time, the spherical LED lamp 10 performs a full range of polishing operations synchronously through sliding friction with the inner annular surface of the polishing block 9, thereby solving the problem of polishing dead angles under traditional mechanical clamping.

[0019] Then, the device also performs a 45° chamfering treatment on the front and rear sides of the inner annular surface of the polishing block 9, so that the chamfered part of the inner annular 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 inner annular surface of the polishing block 9 needs to change the radius to adapt thereto. At this time, the ball screw 6 is provided to drive the slider 7 and the polishing block 9 to move forward or backward, so that the chamfered inclined surface of the inner annular surface of the polishing block 9 moves to the top of 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, thereby significantly enhancing the adaptability of the device.

[0020] The bracket 2 is fixedly mounted on the top of the polishing box 1, the telescopic rod 3 is mounted on the top of the bracket 2, the slider 7 is slidably mounted on the outer surface of the support 5, and a through groove 8 is provided at the bottom of the front of the slider 7; The slider 7 is slidably installed on the outer surface of the pillar 5. It is driven by the ball screw 6 and moves back and forth along the outer surface of the pillar 5, so that the inner annular surface of the polishing block 9 can be adjusted in position according to the size of the spherical LED lamp 10. The through groove 8 helps to enhance 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 the vicinity of the exhaust port 17.

[0021] Among them, the front and rear sides of the inner annular surface of the polishing block 9 are both provided with chamfers, and the chamfer angle is 45°; 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 and drive the polishing block 9 to move forward or backward, so that the inclined surface where the chamfer on the inner ring surface of the polishing block 9 is located can be adapted and abutted against the outer surface of the spherical LED lamp 10, thereby adapting to the outer surface of the spherical LED lamp 10 for polishing.

[0022] The second spring 19 is located at the bottom of the inner cavity of the support tube 18 and provides elastic support for the support rod 20, so that the first steel ball 22 can maintain contact with the bottom of the spherical LED lamp 10; Spring 2 19, support rod 20, fixing block 1 21 and steel ball 1 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 inevitably change. At this time, spring 2 19 elastically supports the support rod 20 upward, thereby providing an elastic rotation support guarantee for the spherical LED lamp 10.

[0023] The cross-sectional shape of the polishing block 9 is a semicircular ring, and the polishing block 9 can move in the front-rear direction under the drive of the ball screw 6; The semicircular ring design of the polishing block 9 allows its interior to always fit in contact with the outer surface of the polishing block 9 , and combined with the movement of the polishing block 9 in the front-to-back direction, it can perfectly adapt to the polishing work of spherical LED lamps 10 of different sizes.

[0024] Wherein, a buffer pad 14 is glued to the bottom of the extension frame 13, and the buffer pad 14 is made of a rubber block; The extension frame 13 can move downward a certain distance under the action of the high-pressure airflow. At this time, the buffer pad 14 can provide buffer protection for the bottom opening of the extension frame 13 to avoid rigid damage when the bottom of the extension frame 13 contacts the spherical LED lamp 10.

[0025] The device also narrows the bottom opening of the extension frame 13 through the 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 to rotate by the compressed air is polishing, the high-pressure airflow continuously rushing 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, the high-pressure airflow can remove all impurities generated by polishing. Since the exhaust port 17 is opened at the bottom of the polishing box 1, the impurities carried away by the high-pressure airflow can be discharged from the exhaust port 17, thereby realizing the efficient surface cleaning function of the device.

[0026] The top of the inner wall of the block 16 is designed to be inclined, and a gas passage that is wide at the top and narrow at the bottom is formed between the two groups of blocks 16; The block 16 can accelerate the compressed air from the connecting pipe 12 through the narrowed air passage, thereby increasing the flow rate of the compressed air and reducing the energy loss of the compressed air after leaving the extension frame 13 .

[0027] The bottom of the polishing box 1 is provided with an exhaust port 17, and 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; The extension frame 13 discharges high-pressure airflow downward to drive the spherical LED lamp 10 to rotate, and simultaneously cleans impurities generated on the surface of the spherical LED lamp 10 due to polishing.

[0028] Working principle: First, start the telescopic rod 3, and drive the polishing block 9 to the highest point through the mounting frame 4 and the slider 7, and connect the connecting pipe 12 to the air compressor to stand by, put the spherical LED lamp 10 into the device, so that the outer surface of the spherical LED lamp 10 first contacts the steel ball 22, and press the fixing block 21 and the support rod 20 downward, compress the spring 2 19, until the outer surface of the spherical LED lamp 10 simultaneously abuts against the outer surface of the steel ball 25; Then, the telescopic rod 3 is started, and the polishing block 9 and the placement frame 11 are driven to move downward through the mounting frame 4 and the slider 7, so that the inner annular surface of the polishing block 9 is adapted to abut against the outer surface of the spherical LED lamp 10, and the telescopic rod 3 is closed. Then, the air compressor continuously inputs a large amount of high-pressure gas into the placement frame 11 through the connecting pipe 12, first blows the extension frame 13 downward, and makes the bottom opening of the extension frame 13 quickly approach the outer surface of the spherical LED lamp 10, and then, the high-pressure airflow increases the flow rate through the inner cavity of the extension frame 13 and the gradually narrowing air passage between the two groups of blocks 16, and acts downward on the surface of the spherical LED lamp 10, so that the spherical LED lamp 10 moves clockwise at high speed around its own axis under the blowing of the airflow. In this process, the steel ball 25 and the steel ball 1 22 rotate synchronously and provide rotation support. At the same time, the surface of the spherical LED lamp 10 slides and rubs against the inner annular surface of the polishing block 9 during the rotation, and the surface of the spherical LED lamp 10 is fully polished; Finally, when the polishing of the spherical LED lamp 10 is completed, the polishing block 9 only needs to be lifted to the highest point to take out the spherical LED lamp 10 and complete the unloading. When facing spherical LED lamps 10 of different sizes, such as Figure 4 As shown, spring 2 19 provides elastic support for support rod 20, so that steel ball 1 22 can always abut against the bottom of spherical LED lamp 10, start ball screw 6, and drive slider 7 and polishing block 9 to move forward or backward, so that the chamfered inclined surface on the inner ring surface of polishing block 9 is adapted to abut against the outer surface of spherical LED lamp 10, and the front and rear positions of polishing block 9 are adjusted according to the size of spherical LED lamp 10, so that the inner ring surface of spherical LED lamp 10 can be adapted to abut against spherical LED lamp 10.
