Description

Technical Field

[0001] The invention relates to the technical field of protective devices, in particular to a protective device for precision machining of optoelectronic components. Background Art

[0002] Optoelectronic technology is a comprehensive high-tech that has developed rapidly in the past three decades following microelectronic technology. In the processing of optoelectronic products, light processing is often used, but light processing will produce strong light that may cause damage to people's eyes. Therefore, supporting protective devices are required for production. The existing protective devices for precision processing of optoelectronic parts can basically meet daily use needs, but there are still some shortcomings that need to be improved. Most of the existing protective devices for precision processing of optoelectronic parts use traditional handheld devices, which require users to hold them in their hands when used. However, the handheld method of use will cause sore arm muscles and excessive labor intensity after long-term use of the user, and the exhaust gas generated during processing may be directly inhaled into the body, causing unnecessary harm to the body, and the particulate matter in the exhaust gas may also adhere to the surface of the optoelectronic parts, affecting the service life of the optoelectronic parts.

[0003] For example, a Chinese patent with publication number "CN216264905U" discloses "a protective device for precision machining of optoelectronic components", whose main structure includes a workbench, a placing table is arranged at the center of the upper surface of the workbench, support rods are fixedly connected to the inside of the workbench at equal intervals, a processing assembly is installed on the top of the support rods, a protective box is slidably connected to the inside of the workbench, sliding holes are opened at equal intervals on the surface of the protective box, racks are installed on both sides of the inside of the protective box, a motor is installed inside the workbench, a driving gear is installed at one end of the motor, and a transition gear is meshed and connected at the other end of the motor, a rotating rod is installed at the inner center of the transition gear, the outer surfaces of the driving gear and the transition gear are meshed and connected with a second gear, a long rod is installed at the inner center of the second gear, and the outer surface of the long rod is fixedly connected to the first gear.

[0004] By carefully understanding the protective device for precision machining of the above-mentioned optoelectronic components, it can be learned that: the protective device for precision machining of optoelectronic components, 1. By setting up a protective box, the optoelectronic components can be protected when they are being processed, and by setting a first gear and a rack, the protective box can be automatically extended and retracted, thereby enhancing practicality; 2. By installing a cleaning component, the exhaust gas inside the protective box can be discharged in time to prevent particulate matter from adhering to the optoelectronic components, affecting the service life of the finished optoelectronic components, thereby enhancing safety.

[0005] However, in actual work, the protective box is what truly performs the protective function. During the understanding process, the motor rotates to drive the active gear to rotate. At this time, one end of the active gear drives the second gear at one end of the protective box to rotate, and the other end of the active gear drives the second gear at the other end of the protective box to rotate through the transition gear. The second gear drives the first gear to rotate through the long rod. At this time, the first gear drives the protective box to slide up and down inside the workbench through the rack. Therefore, the extension and retraction of the protective box requires the directional drive of the motor, and the passive protection effect cannot be achieved at all, which seriously reduces the work efficiency. In addition, the optoelectronic processing device needs to adjust the distance between the photoelectric emitter and the optoelectronic component in the optoelectronic processing device according to actual conditions. Since there is no corresponding maximum diving depth limit structure between the photoelectric emitter and the optoelectronic component, there is a phenomenon that the photoelectric emission of the optoelectronic component is broken due to the excessive diving depth of the photoelectric emitter, which poses certain safety hazards.

[0019] 1. It has the ability to follow and retract dynamically, and can autonomously adjust the spatial position of the protective cover according to the specific height of the photoelectric emitter in the optoelectronic processing device. Therefore, there is no need to manually adjust the position of the protective cover, thereby improving the processing efficiency.

[0031] 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.

[0032] See also Figure 1 , Figure 2 and Figure 3 A protective device for precision machining of optoelectronic components, comprising a cylindrical worktable 1 with support legs 2 installed at the bottom, a component installation cavity 3 arranged at the axial center of the cylindrical worktable 1, an annular movable cavity 4 arranged on the inner side of the circumferential surface of the cylindrical worktable 1, an annular limiting opening 5 arranged at the top of the annular movable cavity 4, a plurality of track grooves 6 arranged on the circumferential surface of the cylindrical worktable 1 and a plurality of main gas limiting holes 7 arranged at the bottom of the cylindrical worktable 1 and connected to the annular movable cavity 4. The cylindrical worktable 1 is placed directly below the electronic processing device, and it should be noted that the upper open end of the protective cover 82 needs to be in a state of interference with the bottom end of the photoelectric emitter in the electronic processing device, so that the protective cover 82 can ensure longitudinal movement with the photoelectric emitter.

[0033] To achieve follow-up optoelectronic protection, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5, it is necessary to set up a telescopic protection mechanism 8, which is provided with a protective cover 82 that can be telescopically moved in the longitudinal direction, a longitudinal telescopic rod 89 that moves longitudinally with the protective cover 82, and a coil spring 87 that produces an elastic damping effect on the downward movement of the protective cover 82 and forces the protective cover 82 to return upward. When it is necessary to adjust the working gap between the photoelectric emitter and the optoelectronic component according to actual conditions, since the upper opening of the protective cover 82 is in a state of conflict with the bottom end of the photoelectric emitter in the electronic processing device, when the photoelectric emitter moves longitudinally, under the elastic action of the coil spring 87, the protective cover 82 will follow the longitudinal movement of the photoelectric emitter, and at the same time, the optoelectronic component is always protected. Inside it, a follow-up optoelectronic component protection function is realized. At the same time, during the movement of the protective cover 82, the piston body 86 moves accordingly. When the piston body 86 moves, the air pressure value inside the longitudinal telescopic chamber 85 will change. Due to the existence of the auxiliary gas limit hole 88, a certain damping effect will be produced on the movement of the piston body 86, so that the movement of the components is in a stable state, thereby improving the working stability of the equipment. Therefore, the equipment has a passive follow-up telescopic capability and can autonomously adjust the spatial position of the protective cover according to the specific height of the photoelectric emitter in the optoelectronic processing device. Therefore, there is no need to manually adjust the position of the protective cover, thereby improving the processing efficiency.

[0034] For the specific structure of the telescopic protection mechanism 8, please refer to Figure 4 and Figure 5 , including a clamping ring 81 located inside the annular movable cavity 4 and capable of moving longitudinally along the annular movable cavity 4 and a plurality of longitudinal telescopic shells 83, the upper annular surface of the clamping ring 81 is embedded with a protective cover 82 that passes through the annular limit opening 5, in order to prevent the components from being separated, it is necessary to make the difference between the inner ring and the outer ring of the clamping ring 81 greater than the difference between the inner ring and the outer ring of the protective cover 82, and the difference between the inner ring and the outer ring of the clamping ring 81 matches the difference between the inner ring and the outer ring of the annular movable cavity 4, and the difference between the inner ring and the outer ring of the protective cover 82 matches the difference between the inner ring and the outer ring of the annular limit opening 5. In order to provide protection and facilitate observation, it is necessary to make the protective cover 82 a cylindrical structure made of a transparent material, and the longitudinal telescopic shell The bottom end of 83 is provided with a bottom fixing plate 84 which is an integral structure with it and fixedly mounted on the bottom surface of the annular active chamber 4. The interior of the longitudinal telescopic shell 83 is provided with a longitudinal telescopic chamber 85. The longitudinal telescopic shell 83 is provided with a piston body 86 which can move longitudinally along the longitudinal telescopic chamber 85. The bottom end of the piston body 86 is provided with a coil spring 87 in a compressed state. The bottom end of the longitudinal telescopic shell 83 is provided with a secondary gas limit hole 88 corresponding to the main gas limit hole 7. The upper end surface of the piston body 86 is fixedly mounted with a longitudinal telescopic rod 89 which passes through the longitudinal telescopic shell 83. The top end of the longitudinal telescopic rod 89 is fixedly mounted on the bottom annular end surface of the retaining ring 81.

[0035] In order to limit the maximum diving depth of the photoelectric transmitter, so as to prevent the photoelectric components from being impacted due to excessive diving stroke, and thus form a stable safety protection for the photoelectric components during the processing, please refer to Figure 1 , Figure 2 , Figure 6 and Figure 7 , it is necessary to set a downward movement depth limiting mechanism 9, which is internally provided with an inner fixed sleeve 91 fixedly placed on the circumferential side of the cylindrical workbench 1, a threaded sleeve 92 installed on the periphery of the inner fixed sleeve 91 through a threaded structure 93, an outer rotating sleeve 94 installed on the periphery of the threaded sleeve 92 through a bearing, and a limiting collar 97 placed on the periphery of the longitudinal telescopic rod 89 and capable of longitudinally moving with the outer rotating sleeve 94, and limiting the downward movement depth of the protective cover 82. According to actual conditions, it is necessary to make the horizontal height of the upper end face of the limiting collar 97 higher than the horizontal height of the upper surface of the optoelectronic component after being adsorbed during operation. When adjusting, by rotating the threaded sleeve 92, since the threaded structure 93 includes an external threaded structure arranged on the outer circumferential surface of the inner fixed sleeve 91 and a structure The internal thread structure disposed on the inner circumferential surface of the threaded sleeve 92, and the external thread structure matching the internal thread structure, will enable the threaded sleeve 92 to drive the outer rotating sleeve 94 to move longitudinally, and the limiting collar 97 will move axially along the longitudinal telescopic rod 89. After the adjustment is completed, once an operation error occurs and the photoelectric transmitter moves excessively downward, when the bottom end of the retaining ring 81 touches the limiting collar 97, since the limiting collar 97 is in a fixed height state, the retaining ring 81 cannot move further downward, and the photoelectric transmitter is blocked from moving downward, thereby limiting the maximum diving depth of the photoelectric transmitter, thereby preventing the optoelectronic components from being impacted due to an excessive diving stroke, thereby forming a stable safety protection for the optoelectronic components during the processing process.

[0036] For the specific structure of the downward movement depth limiting mechanism 9, please refer to Figure 6 and Figure 7 , including an inner fixed sleeve 91 and a limiting collar 97 fixedly placed on the circumferential side of the cylindrical workbench 1, the circumferential surface of the inner fixed sleeve 91 is installed with a threaded sleeve 92 through a threaded structure 93, the threaded sleeve 92 is installed with an outer rotating sleeve 94 on the circumferential surface near its top through a bearing, the upper annular end surface of the outer rotating sleeve 94 is clamped with a plurality of blocks 95, each of the blocks 95 is installed with a horizontal limiting rod 96 that passes through the corresponding track slide groove 6 on the inner wall facing the track slide groove 6, the center of the limiting collar 97 is provided with an annular hole 98, each of the horizontal limiting rods 96 is fixedly connected to the circumferential surface of the corresponding limiting collar 97 at one end extending into the interior of the track slide groove 6, and the annular hole 98 is sleeved on the outer periphery of the rod body of the longitudinal telescopic rod 89 in a manner that it can slide longitudinally relative to the longitudinal telescopic rod 89.

[0037] In order to achieve the adsorption fixation of optoelectronic components and remove the smoke particles generated during the processing, please refer to Figure 1 , Figure 2 and Figure 8 , it is necessary to set up an adsorption-type component fixing mechanism 10, which is provided with a support plate 1011 installed on the top of the component installation cavity 3, a rubber sealing ring 1012 arranged on the upper surface of the support plate 1011, a smoke suction hole 1013 arranged in the support plate 1011 and located on the periphery of the rubber sealing ring 1012, an air suction hole 1014 arranged in the support plate 1011 and located on the inner side of the rubber sealing ring 1012, and a turbine blade 1010 located below the cylindrical workbench 1 and capable of making air flow from top to bottom when rotating. First, the bottom surface of the optoelectronic component is placed on the upper end surface of the rubber sealing ring 1012, and the drive is started. The motor 105 is driven and the turbine blades 1010 rotate rapidly. At this time, the internal air pressure of the closed area formed between the bottom surface of the optoelectronic component and the inner circumference of the rubber sealing ring 1012 will be reduced, thereby forming a low-pressure phenomenon. The low-pressure phenomenon will cause the optoelectronic component to be adsorbed, thereby achieving adsorption-type fixation of the optoelectronic component. The optoelectronic component will generate smoke particles during the processing. Due to the fluidity of the gas, the smoke particles will be adsorbed through the smoke suction hole 1013 and discharged to the outside through the exhaust channel 107, thereby achieving adsorption-type fixation of the optoelectronic component while removing the smoke particles generated during the processing.

[0038] During operation, the amount of gas discharged during the rotation of the turbine blades 1010 is H, the amount of gas adsorbed through the smoke intake hole 1013 is h1, and the amount of gas adsorbed through the intake hole 1014 is h2. Since the intake hole 1014 is blocked later, h2 is almost zero. However, air adsorption will cause low pressure to form inside the above-mentioned closed area. By controlling the rotation speed of the drive motor 105, the value of the low pressure can be controlled, thereby controlling the suction strength when the optoelectronic component is adsorbed. The suction must be sufficient to allow the optoelectronic component to be adsorbed and fixed.

[0039] For the specific structure of the adsorption-type component fixing mechanism 10, please refer to Figure 8, further comprising a hemispherical shell 101, wherein the bottom of the hemispherical shell 101 is provided with a longitudinal channel 102 of an integral structure therewith, the bottom end of the longitudinal channel 102 is provided with a turbine mounting shell 103 of an integral structure therewith, and the top of the hemispherical shell 101 is provided with a support plate 1011 of an integral structure therewith, the hemispherical shell 101, the longitudinal channel 102 and the support plate 1011 are fixedly mounted inside the component mounting cavity 3, and a rubber sealing ring 1012 is embedded in the upper end surface of the support plate 1011, in order to have a negative The top structure of the rubber sealing ring 1012 needs to protrude from the upper end surface of the support plate 1011, the hemispherical shell 101 is provided with a hemispherical cavity 109, the support plate 1011 is provided with a smoke suction hole 1013 for sucking the smoke particles above the support plate 1011 into the hemispherical cavity 109 on the periphery of the circumferential surface of the rubber sealing ring 1012, and the support plate 1011 is provided with a gas suction hole 1013 for sucking the smoke particles above the support plate 1011 into the hemispherical cavity 109 on the inner side of the circumferential surface of the rubber sealing ring 1012. The air is sucked into the hemispherical cavity 109, thereby reducing the gas pressure in the gas suction area. The interior of the longitudinal channel 102 is provided with a middle gas flow hole 108 connected to the hemispherical cavity 109. The interior of the turbine mounting shell 103 is provided with a turbine mounting cavity 106 whose air inlet end is connected to the bottom end of the middle gas flow hole 108. The circumferential side of the turbine mounting shell 103 is provided with an exhaust channel 107 which is an integral structure with it and is used to discharge the gas inside the turbine mounting cavity 106. A driving motor 105 is fixedly mounted on the bottom end of 103 through a motor fixing base 104, and the rotor of the driving motor 105 passes through the motor fixing base 104 and the turbine mounting housing 103, and the top end extends to the inside of the turbine mounting cavity 106, and the rotor of the driving motor 105 is installed with turbine blades 1010 inside the turbine mounting cavity 106. The turbine blades 1010 are sucked into the direction of the hemispherical cavity 109 and discharged outward through the exhaust channel 107 along with the gas flow formed when the rotor of the driving motor 105 rotates.

[0040] The specific working principle of the present invention is that the cylindrical workbench 1 is placed directly below the electronic processing device, and the upper open end of the protective cover 82 needs to be in a state of conflict with the bottom end of the photoelectric emitter in the electronic processing device, so that the protective cover 82 can ensure longitudinal movement with the photoelectric emitter;

[0041] During the movement of the protective cover 82, the piston body 86 moves therewith. When the piston body 86 moves, the air pressure value inside the longitudinal telescopic chamber 85 will change. Due to the existence of the auxiliary gas limit hole 88, a certain damping effect will be produced on the movement of the piston body 86, so that the movement of the component is in a stable state.

[0042] Then, the bottom surface of the optoelectronic component is placed on the upper end surface of the rubber sealing ring 1012, and the driving motor 105 is started, and the turbine blade 1010 rotates rapidly. At this time, the air pressure inside the closed area formed between the bottom surface of the optoelectronic component and the inner circumference of the rubber sealing ring 1012 is reduced, thereby forming a low-pressure phenomenon. The low-pressure phenomenon causes the optoelectronic component to be adsorbed, thereby achieving adsorption-type fixation of the optoelectronic component. During the processing of the optoelectronic component, smoke particles are generated. Due to the fluidity of the gas, the smoke particles are adsorbed through the smoke suction hole 1013 and discharged to the outside through the exhaust channel 107.

[0043] After the processing is completed, the driving motor 105 is turned off, and then the protective cover 82 is manually pressed downward to take out the processed optoelectronic component.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
