Description

Lamp tube grinding jig

Technical Field

The utility model belongs to the technical field of the grinding jig and specifically relates to a fluorescent tube grinding jig.

Background

In addition to being used as a lighting device, the lamp tube can be applied to part processing or manufacturing operations by adjusting the emitted light in some industrial fields, for example, a UV lamp tube emitting ultraviolet light, which is a special lamp tube application. After the UV lamp tube is used for a long time, the surface of the UV lamp tube can generate attachments, which further affects the light emitting efficiency and state of the ultraviolet light. For this reason, manufacturers are quite expensive to replace the UV lamps annually.

In order to prolong the service life of the lamp tube and reduce the replacement amount and cost of the lamp tube, it is preferable to remove the attachments on the surface of the lamp tube for reuse, and accordingly, grinding is a technical choice for removing the attachments. Grinding is an operation of solidifying into smaller particles through external force, so as to achieve the purpose of improving the surface smoothness of the material and meeting the production and application requirements. In the field of polishing, a technique that is currently used more frequently is centerless polishing. The centerless grinding positions a ground workpiece between fixed grinding wheels, drives the workpiece to move through devices such as a conveying belt and the like, and then utilizes the fixed shaft rotation of the grinding wheels to enable the surface of the grinding wheels to be in contact with the whole surface of the workpiece so as to achieve the purpose of removing attachments. However, in this way, for the lamp tube, the rotation force of the grinding wheel and the stress generated relatively when the lamp tube is displaced make the lamp tube easily break and damage during the grinding process, and the electrode assembly disposed on the lamp tube is also worn by the contact of the conveyer belt and the grinding wheel. Therefore, the existing grinding jig and mechanism can not be applied to the grinding of the fragile lamp tube with the electrode assembly.

In view of the above, the present inventors have devised and proposed a lamp polishing jig, which is expected to effectively solve the inconvenience of removing the attachments on the surface of the lamp.

Detailed Description

The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.

As mentioned above, in order to effectively grind the lamp tube having the material characteristics of hard, brittle, and fragile electronic components such as electrodes, the inventor devised a jig with a special structure for processing the lamp tube, and eliminated the damage and damage to the lamp tube caused by the grinding operation, so as to facilitate the reuse of the lamp tube after removing the attachments to the lamp tube, and the technical characteristics of the lamp tube grinding jig will be described in detail below.

Please refer to fig. 1 to 6, which are a perspective view, a partial perspective view and application views of a preferred embodiment of the present invention. The utility model discloses a fluorescent tube grinds tool 1 for grind the surface of a fluorescent tube 2, and the both ends of fluorescent tube 2 have an electrode portion 20 respectively. Preferably, the lamp tube 2 may be a UV lamp tube for emitting ultraviolet light, and the lamp tube 2 generates an attachment of silicon crystals on its surface after a long time use. The lamp polishing jig 1 comprises two holding members 10, a moving device 11 and a polishing member 12. The clamping assemblies 10 are disposed opposite to each other, and each of the clamping assemblies 10 includes two rotating wheels 101 and two fixed pressing wheels 102. The rotating wheel 101 is used for the electrode portion 20 of the lamp 2 to abut against, and the rotating wheel 101 can rotate to drive the lamp 2 to rotate. The fixed pressing wheel 102 is correspondingly disposed above the rotating wheel 101 for pressing the lamp 2. The moving device 11 is correspondingly arranged above the clamping assembly 10 and used for moving back and forth along the central axis A of the lamp tube 2. The polishing assembly 12 is disposed on the moving device 11 and has a polishing belt 121 to be driven by the moving device 11 to polish the surface of the lamp tube 2. Therefore, when the lamp tube 2 is ground, only the electrode portions 20 at the two ends of the lamp tube are respectively and correspondingly disposed at the clamping assembly 10 to form a fixed position, and then the moving device 11 drives the grinding belt 121 of the grinding assembly 12, so that the areas on the surface of the lamp tube 2 can be ground one by one to remove the attachments on the lamp tube 2. Therefore, the surface attachments of the lamp tube 2 can be effectively removed, and the damage of the machine to the lamp tube 2 body and the electrode part 20 in the grinding process can be eliminated.

Furthermore, the fixed pressing wheel 102 and the rotating wheel 101 of the clamping assembly 10 have the function of effectively fixing the electrode portion 20, and the electrode portion 20 of the lamp 2 is reliably disposed on the two rotating wheels 101 and driven by the rotation of the rotating wheels 101, i.e. the lamp 2 is driven to rotate by the rotatable design of the rotating wheels 101. When the polishing process is to be performed, the rotating wheel 101 is fixed to be beneficial to match with the fixed pressing wheel 102 to fix and press the lamp tube 2, and then the moving device 11 drives the polishing assembly 12 to polish the surface of the lamp tube 2. After the surface of one side of the lamp tube 2 is ground, the fixed pressing wheel 102 is slightly away from the lamp tube 2, and the rotating wheel 101 is driven to rotate, so that the lamp tube 2 rotates to the surface of the other side for further grinding. Of course, through the automatic control technique, the rotating wheel 101 can also be rotated continuously during the polishing process to drive the lamp tube 2 to have all the areas on the surface thereof polished by the polishing belt 121 to remove the attachments. The moving device 11 can be a robot arm, and can move along the central axis a of the lamp 2, and also can vertically move up and down, so that the moving device 11 drives the grinding component 12 to approach or move away from the lamp 2, thereby facilitating the grinding or the replacement of the lamp 2, etc.

Preferably, the polishing assembly 12 further includes a plurality of driving wheels 122, and the polishing belt 121 is disposed outside the driving wheels 122, such that the polishing belt 121 rotates in response to the rotation of the driving wheels 122, as shown in fig. 2. When the polishing operation is to be performed, the driving wheels 122 are started, and the polishing belt 121 sleeved outside the driving wheels 122 is rotated by the rotation of the driving wheels 122, so that the polishing belt contacts the surface of the lamp tube 2 and is driven by the rotation to achieve the polishing effect. Further, the polishing assembly 12 may further include an adjusting member 123 connected to the driving wheel 122 for controlling the tightness of the polishing belt 121 and changing the polishing force of the polishing belt 12 relative to the surface of the lamp 2. In the present embodiment, the adjusting member 123 is an elastic member assembled with the driving wheel 122, and the position of the driving wheel 122 can be adjusted by the stretching state thereof to change the tightness of the polishing belt 121.

To facilitate the grinding operation and improve the grinding efficiency, the lamp grinding jig 1 may further include a dust collecting device 13 disposed at one side of the two clamping assemblies 10 for collecting the dust generated after the grinding of the lamp 2. Further, in the present embodiment, the dust collecting device 13 includes a dust collecting motor 131 and a cover 132, the cover 132 is located at one side of the clamping assembly 10, and the dust collecting motor 131 is connected to the cover 132 so as to make the dust enter the cover 132 through the suction force of the dust collecting motor 131. During the grinding process, the dust collecting motor 131 can be synchronously started to make the cover 132 generate suction force in response to the dust collecting motor 131, so that the dust or debris generated after the surface of the lamp 2 is ground is sucked into the cover 132 by the suction force and collected, thereby reducing the influence of the retained dust or debris on the grinding process.

In addition, the lamp polishing jig 1 may further include a seat 14 disposed between the two clamping assemblies 10 to make a portion of the tube body of the lamp 2 abut against the upper portion. Therefore, when the polishing assembly 12 polishes the surface of the lamp tube 2, the seat 14 can generate a supporting force relative to the lamp tube 2, so that the lamp tube 2 is not displaced or deviated due to the polishing force, and the polishing operation is more stable, and a preferred implementation state is that the seat 14 is in a strip structure, and can directly support the region of the lamp tube to be polished. Further, another preferred implementation state is that the seat 14 is movably disposed on a slide rail 3, so that when the polishing tape 121 performs a polishing operation relative to the lamp 2, the seat 14 moves along the slide rail 3 and keeps corresponding to the polishing tape 121. The seat 14 is movable through the structure of the slide rail 3, the seat 14 can be designed according to the size of the polishing tape, and during the polishing operation, the seat 14 moves along with the displacement of the moving device 11, so that the seat 14 and the polishing tape 121 are kept corresponding, and the seat 14 can reliably support the current polishing area of the lamp 2.

In order to facilitate the fixed pressing wheel 102 to move relative to the rotating wheel 101 to form an open or clamping state, so that the lamp 2 can be placed on the lamp polishing jig 1 or removed from the lamp polishing jig 1, preferably, the clamping assembly 10 further comprises a movable bracket 103 respectively, and the fixed pressing wheel 102 is disposed on the movable bracket 103 to move relative to the rotating wheel 101 through the movable bracket 103. Therefore, when the lamp 2 is to be placed or the lamp 2 is to be ground in a side-changing manner, the movable bracket 103 is used to make the fixed pressing wheel 102 away from the rotating wheel 101 to form an open state, so as to remove the lamp 2, or the rotatable rotating wheel 101 is used to drive the lamp. When the polishing process is desired, the fixed pinch roller 102 is pressed against the electrode portion 20 of the lamp tube 2 again through the movable bracket 103 to form a fixed clamping state.

In application, as shown in fig. 4 to 6, the electrode portions 20 at two ends of the lamp tube 2 are respectively abutted against the rotating wheels 101 of the clamping assembly 10, and then the fixed pressing wheel 102 is pressed against the lamp tube 2 to complete the step of placing the lamp tube 2. Then, the moving device 11 drives the grinding assembly 12 to move toward the lamp tube 2 with the grinding assembly 12, the grinding belt 121 contacts the surface of the lamp tube 2 to drive the grinding assembly 12, the attachments on the surface of the lamp tube 2 are ground off by the grinding belt 121, and the removed attachments, i.e., dust or debris, can be collected by the dust collecting device 13 to eliminate the influence of the dust or debris on the grinding operation, as shown in fig. 4 and 5. After the surface of one side of the lamp tube 2 is ground, the moving device 11 can be reset, the fixed pressing wheel 102 is slightly away from the rotating wheel 101, the rotating wheel 101 is driven to drive the lamp tube 2 to rotate and turn over to expose the surface of the other side, and then the fixed pressing wheel 102 is pressed against the lamp tube 2 again to fix the lamp tube 2 again for grinding operation, as shown in fig. 6. Of course, the contact area between the lamp 2 and the polishing belt 121 can be adjusted by the rotation of the rotating pulley 101 in the polishing operation as described above. Wherein, the base 14 can move along the slide rail 3 and support according to the position of the polishing belt 121 relative to the polishing lamp 2, so that the polishing operation is more stable and reliable. The above-mentioned grinding operation steps are only a preferred example, and the operation steps of the lamp tube grinding jig 1 of the present invention can be slightly adjusted according to the operation requirements.
