Description

Technical Field

[0001] This application relates to the technical field of eyeglasses exterior manufacturing, and in particular to a processing device for painting eyeglass frames. Background Technology

[0002] Currently, eyeglasses, as everyday items that combine practicality and fashion, have their appearance quality directly impacting the consumer experience. In the eyeglass manufacturing process, the painting stage is particularly crucial, requiring not only a uniform paint layer covering the frame, temples, and other components, but also meeting the diverse color and gloss requirements of different designs. Traditional painting methods rely on manual operation, resulting in low efficiency and poor consistency. With the development of automation technology, eyeglass painting equipment is gradually evolving towards mechanization and intelligence, aiming to improve painting precision and production efficiency through structural optimization and control innovation, while reducing the potential impact of human intervention on product quality.

[0003] In related technologies, a painting device for mirror frames includes a processing table, a mounting rod, a fixing rod, and a spray gun. The processing table has a processing groove on its upper side, and one vertical sidewall of the processing groove is rotatably connected to one end of the fixing rod, while the other end is fixed to the mounting rod with screws. The fixing rod can rotate around its own axis. A linear guide rail is fixed horizontally along the edge of the processing groove opening, and a slider is slidably mounted on the linear guide rail. A paint spraying rod is integrally formed on the slider horizontally. A spray gun facing the bottom of the processing groove is mounted on the side of the paint spraying rod, and the spray gun can reciprocate horizontally under the action of the linear guide rail. During painting, the mirror frame is first fixed to the mounting rod, then the mounting rod and fixing rod are coaxially connected with screws. The spray gun is then started, and the fixing rod is manually rotated to achieve all-around painting.

[0004] In the aforementioned related technologies, workers typically prepare multiple mounting rods in advance and pre-fix the frames to be painted onto spare mounting rods. Once the frames on one mounting rod have been painted, they need to be removed from the fixed rod and replaced with a spare mounting rod to continue the work. However, this disassembly and assembly process requires the use of special tools, such as screwdrivers and wrenches. Using tools not only takes a long time and reduces production efficiency, but also increases the labor intensity of workers, indicating room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a processing device for painting mirror frames, which solves the problem in the above-mentioned related technologies that require special tools to disassemble and assemble the mounting rod, thus wasting time and reducing production efficiency.

[0006] The technical solution of the painting equipment for mirror frames provided in this application is as follows: A painting processing device for mirror frames includes a processing table and a mounting rod for mounting the mirror frames. The processing table has a processing groove and a spraying assembly for painting the mirror frames on the mounting rod. A fixing rod is vertically fixed to the vertical side wall of the processing groove along the horizontal direction. A positioning rod is rotatably connected to the side wall of the processing groove away from the fixing rod, coaxial with the fixing rod and rotating about its own axis. A clearance groove is formed on the end face of the positioning rod away from the fixing rod, and a fixing notch is formed at the opening edge of the clearance groove. A fixing block is fixed to the outer periphery of one end of the mounting rod. A first slot coaxial with the clearance groove is formed on the end face of the fixing rod, and a first notch communicating with the first slot is formed on the outer periphery of the fixing rod. A protective sleeve is slidably mounted on the outer periphery of the fixing rod. The fixing block can be inserted into the fixing notch simultaneously after one end of the mounting rod is inserted into the clearance groove, and the other end of the mounting rod can be inserted into the first slot through the first notch. The protective sleeve can seal and release the opening of the first notch when sliding back and forth.

[0007] By adopting the above technical solution, during installation, simply align the part of the mounting rod with the fixing block at one end with the recess on the positioning rod, and insert the fixing block into the fixing notch simultaneously to complete the initial positioning of that end; then insert the other end of the mounting rod into the first slot through the first notch on the fixing rod to achieve overall installation and positioning. The operation is simple and convenient, requiring no special tools for disassembly and assembly, improving installation efficiency and allowing workers to quickly set the frame on the mounting rod, thereby carrying out subsequent painting work more efficiently and improving the overall practicality and production efficiency of the frame painting processing equipment.

[0008] Optionally, a drive motor with its output shaft facing the positioning rod is fixedly installed inside the processing table in the horizontal direction. The output shaft of the drive motor is coaxially and fixedly connected to the end of the positioning rod away from the fixed rod. The drive motor can drive the positioning rod to rotate the mounting rod around its own axis.

[0009] By adopting the above technical solution, compared with manual rotation, motor drive can provide continuous and stable power, effectively avoiding the fluctuation of rotation speed caused by factors such as physical strength and operating habits during manual operation. This ensures that the frame rotates at a constant speed during the painting process, so that the paint layer evenly covers all parts of the frame, greatly improving the uniformity and quality of the paint spraying.

[0010] Optionally, the outer circumferential surface of the fixing rod is provided with an elastic element that limits the sliding state of the protective sleeve, and the inner wall of the protective sleeve is provided with a plurality of positioning grooves, and the elastic element can be engaged and disengaged from the positioning grooves during the sliding process of the protective sleeve.

[0011] By adopting the above technical solution, when the protective sleeve slides, the elastic element can be engaged in different positioning grooves, so that the protective sleeve is effectively fixed in a specific position, preventing it from sliding randomly due to vibration and other factors during equipment operation, ensuring the stability of the first notch opening being sealed or unsealed, and guaranteeing the reliability of equipment operation.

[0012] Optionally, the outer circumferential surface of the fixing rod is provided with an installation groove for inserting an elastic element, the elastic element including a spring and a positioning protrusion; one end of the spring presses one side of the positioning protrusion to make a part of the positioning protrusion protrude out of the opening of the installation groove, the protruding part of the positioning protrusion is an arc surface, and the arc length corresponding to the arc surface of the protruding part is a minor arc.

[0013] By adopting the above technical solution, the arc surface design can play a good guiding role during the sliding process of the protective sleeve, making the contact and separation between the positioning protrusion and the positioning groove on the inner wall of the protective sleeve smoother and more seamless, reducing jamming, reducing component wear, and extending the service life of the equipment; at the same time, the inferior arc design makes the engagement and disengagement of the positioning protrusion and the positioning groove more effortless and precise, and the operator can easily push the protective sleeve to achieve position switching without applying excessive external force.

[0014] Optionally, a push rod is fixed on the outer circumferential surface of the protective sleeve, and the push rod can drive the protective sleeve to slide back and forth in the horizontal direction.

[0015] By adopting the above technical solution, the staff does not need to directly contact the protective sleeve. They only need to hold the push rod and apply a horizontal force to easily drive the protective sleeve to slide back and forth in the horizontal direction, so as to achieve the sealing and unsealing operation of the first notch opening.

[0016] Optionally, a push ring is fixedly provided at the end of the push rod away from the protective sleeve, and an anti-slip sleeve is fixedly provided on the push ring.

[0017] By adopting the above technical solution, compared with directly operating the push rod, the push ring can better distribute the force applied by the hand, making the operation more effortless and stable. Especially when performing long-term or frequent sliding operations of the protective sleeve, it can effectively reduce hand fatigue.

[0018] Optionally, a guide rod parallel to the fixing rod is fixed on the inner wall of the processing groove away from the positioning rod, and a fixed through hole is opened on the push rod for the guide rod to pass through.

[0019] By adopting the above technical solution, the cooperation between the guide rod and the fixed through hole ensures that the push rod can only move horizontally in a straight line along the axis of the guide rod, effectively avoiding deviation, shaking or tilting of the push rod during sliding, and ensuring the smoothness and accuracy of the sliding of the protective sleeve.

[0020] Optionally, a knob is detachably connected to the end face of the guide rod facing the positioning rod, the knob preventing the push rod from slipping off the guide rod.

[0021] By adopting the above technical solution, the knob plays a crucial limiting role when the push rod slides on the guide rod. It can effectively prevent the push rod from slipping off the guide rod due to operational errors or the inertia of the equipment during operation, thus avoiding the displacement of the protective sleeve and preventing the equipment from malfunctioning. This ensures the stability and safety of the equipment operation. Moreover, the knob adopts a detachable connection method. When it is necessary to install, debug, maintain or clean the equipment, the knob can be removed to facilitate the removal of the push rod from the guide rod, providing convenience for the maintenance operation of the equipment.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. During installation, simply align the part of the mounting rod with the fixing block at one end with the recess on the positioning rod, and insert the fixing block into the fixing notch simultaneously to complete the initial positioning of that end; then insert the other end of the mounting rod into the first slot through the first notch on the fixing rod to achieve overall installation and positioning. The operation is simple and convenient, requiring no special tools for disassembly and assembly, which improves installation efficiency and allows workers to quickly set the frame on the mounting rod, thereby carrying out subsequent painting work more efficiently and improving the overall practicality and production efficiency of the frame painting equipment. 2. When the push rod slides on the guide rod, the knob plays a crucial limiting role, effectively preventing the push rod from slipping off the guide rod due to operational errors or the inertia of the equipment during operation. This avoids displacement of the protective sleeve, which could cause the equipment to malfunction, thus ensuring the stability and safety of the equipment operation. Moreover, the knob adopts a detachable connection method, which can be removed when the equipment needs to be installed, debugged, maintained, or cleaned, making it convenient to remove the push rod from the guide rod and providing convenience for equipment maintenance operations.

[0026] The present application will be further described in detail below with reference to all the accompanying drawings.

[0027] Example 1: Reference Figure 1 , Figure 2 and Figure 3 A painting processing device for mirror frames includes a processing table 1 and a mounting rod 4 for mounting the mirror frames. The processing table 1 has a processing groove 11 and a spraying assembly 12 for painting the mirror frames on the mounting rod 4. A fixing rod 2 is vertically installed on the vertical side wall of the processing groove 11 along the horizontal direction, and the fixing rod 2 is installed on the vertical side wall of the processing groove 11 by welding. A positioning rod 3 is rotatably connected to the side wall of the processing groove 11 away from the fixing rod 2, which is coaxial with the fixing rod 2 and rotates around its own axis. A clearance groove 31 is provided on the end face of the positioning rod 3 away from the fixing rod 2, and a fixing notch 311 is provided at the opening edge of the clearance groove 31. A fixing block 41 is integrally formed on the outer periphery of one end of the mounting rod 4. A first slot 21 coaxial with the clearance groove 31 is provided on the end face of the fixing rod 2, and a first notch 22 communicating with the first slot 21 is provided on the outer periphery of the fixing rod 2. A protective sleeve 5 is slidably provided on the outer periphery of the fixing rod 2. Before painting, the fixing block 41 can be inserted into the fixing notch 311 at one end of the mounting rod 4 after being inserted into the recessed groove 31, and the other end of the mounting rod 4 can be inserted into the first slot 21 through the first notch 22. When painting, the operator can seal the opening of the first notch 22 by holding the protective sleeve 5 and sliding it. When it is necessary to replace the mounting rod 4 to paint the next batch of frames, the sealing of the first notch 22 can also be released by holding the protective sleeve 5 and sliding it.

[0028] Reference Figure 4 The spraying assembly 12 includes a spray gun 121 and a first drive member 122 that drives the spray gun 121 to slide back and forth; wherein the first drive member 122 can drive the spray gun 121 to slide back and forth in the horizontal direction and spray paint on the mirror frame on the mounting rod 4.

[0029] Reference Figure 3 and Figure 4 Inside the processing table 1, a drive motor 13 with its output shaft facing the positioning rod 3 is fixedly installed in the horizontal direction. The output shaft of the drive motor 13 is coaxially and fixedly connected to the end of the positioning rod 3 away from the fixed rod 2. When the drive motor 13 drives the positioning rod 3 to rotate the mounting rod 4 along its own axis, the fixing block 41 can further ensure that the mounting rod 4 closely follows the positioning rod 3 and rotates stably, thus ensuring the smooth progress of the painting operation.

[0030] The implementation principle of this application embodiment is as follows: During installation preparation, insert the part of the mounting rod 4 with the fixing block 41 into the clearance groove 31 and the fixing notch 311, and insert the other end into the first slot 21 through the first notch 22 to complete the initial installation; During the painting operation, the spray gun 121 of the spraying component 12 slides horizontally back and forth to spray paint under the drive of the first drive component 122. The operator holds the protective sleeve 5 and slides to seal the first notch 22 to prevent the mounting rod 4 from slipping off. At the same time, the drive motor 13 in the processing table 1 drives the positioning rod 3 to drive the mounting rod 4 to rotate stably, ensuring uniform painting in all directions. When replacing the mounting rod 4, the operator can hold the protective sleeve 5 and slide it to release the seal on the first notch 22, remove the original mounting rod 4, and then install the new mounting rod 4 according to the preparation steps to continue the work.

[0031] Example 2: Reference Figure 5 , Figure 6 and Figure 7 The difference between this embodiment and Embodiment 1 is that an elastic element 6 is provided on the outer peripheral surface of the fixing rod 2 to limit the sliding state of the protective sleeve 5, and a plurality of positioning grooves 51 are provided on the inner wall of the protective sleeve 5. The elastic element 6 can be inserted into and removed from the positioning grooves 51 during the sliding process of the protective sleeve 5. The outer circumferential surface of the fixing rod 2 is provided with an installation groove 24 for the elastic element 6 to be inserted, and the elastic element 6 includes a spring 61 and a positioning protrusion 62; one end of the spring 61 presses one side of the positioning protrusion 62 so that a part of the positioning protrusion 62 protrudes out of the opening of the installation groove 24, and the protruding part of the positioning protrusion 62 is an arc surface, and the arc length corresponding to the arc surface of the protruding part is a minor arc. In drive motor 13 (see Figure 4 When rotating, the protective sleeve 5 fitted on the outer circumference of the fixed rod 2 may rotate with it. The presence of the elastic element 6 can effectively fix the protective sleeve 5 and prevent it from swaying left and right under the action of the mounting rod 4, thus ensuring the stability of the equipment operation. When it is necessary to replace the next batch of frames, the staff only needs to slide the protective sleeve 5, and the positioning protrusion 62 will continuously enter and exit the positioning groove 51 to achieve quick and stable positioning adjustment.

[0032] Reference Figure 7 and Figure 8 A push rod 7 is welded to the outer circumferential surface of the protective sleeve 5, and the push rod 7 can drive the protective sleeve 5 to slide back and forth in the horizontal direction; the machining groove 11 is far away from the positioning rod 3 (see Figure 4 The inner wall of the push rod 7 is equipped with a guide rod 8 arranged parallel to the fixed rod 2 by welding. The push rod 7 has a fixed through hole 71 for the guide rod 8 to pass through. When the staff pulls the push rod 7 to slide horizontally, the guide rod 8 can effectively prevent the protective sleeve 5 from rotating along its own axis during the sliding process. This avoids the positioning groove 51 inside the protective sleeve 5 from not coinciding with the positioning protrusion 62 on the fixed rod 2 due to rotation, thus solving the problem of the protective sleeve 5 being difficult to slide due to misalignment.

[0033] Reference Figure 8 and Figure 9 A push ring 72 is fixedly provided at the end of the push rod 7 away from the protective sleeve 5, and an anti-slip sleeve 721 is provided on the outer circumferential surface of the push ring 72. The anti-slip sleeve 721 is made of rubber and is glued to the outer circumferential surface of the push ring 72; the guide rod 8 faces the positioning rod 3 (see Figure 4 The inner wall of the end of the ) is provided with a threaded hole, and the machining table 1 is provided with a knob 81, and a screw that can be screwed into the threaded hole is provided on one side of the knob 81; the knob 81 can be screwed into the opening edge of the guide rod 8 through thread engagement. When the equipment is running, the knob 81 can effectively prevent the push rod 7 from slipping, ensuring continuous and stable operation; the push ring 72 is equipped with a rubber anti-slip sleeve 721, which fits the hand, improves the grip comfort, and helps workers complete the painting efficiently.

[0034] The implementation principle of this application embodiment is as follows: When painting begins, after the worker properly installs the mounting rod 4, they pull the push ring 72, causing the push rod 7 to slide along the guide rod 8. At the same time, the protective sleeve 5 is precisely fixed above the clearance notch with the help of the elastic element 6. When the mounting rod 4 needs to be replaced, the worker pulls the push ring 72, and the positioning protrusion 62 smoothly disengages from the positioning groove 51. Simultaneously, the protective sleeve 5 can be moved away from above the clearance notch. When replacement is needed, the worker needs to remove the old mounting rod 4, replace it with a new rod containing the lens frame to be painted, and then fix the protective sleeve 5 according to the above steps. The whole process is smooth and efficient, ensuring that the equipment can be quickly put into a new round of painting operations.
