Description

Technical Field

[0001] This utility model relates to the field of eyeglass manufacturing equipment technology, specifically to a labeling device for UP stickers on eyeglass temples. Background Technology

[0002] As everyday items used for vision correction, eye protection, or aesthetic purposes, eyeglasses are highly valued for their structural precision and wearing comfort. The temples, a crucial component of eyeglasses, not only support the frame but also often display various labels such as brand logos, material specifications, size parameters, and anti-counterfeiting marks. These labels serve as carriers of product information and important windows for showcasing brand image, directly impacting product recognition and market competitiveness.

[0003] Existing eyeglass temple labeling devices are cumbersome to use, requiring operators to adjust the fixing mechanisms in different directions individually. This lack of coordination between mechanisms increases the need for manual intervention, which can further affect the fixing effect due to improper timing or force, ultimately reducing labeling accuracy and efficiency. Therefore, a new technical solution is proposed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a labeling device for UP stickers on the temples of eyeglasses. This solves the technical problems of the current eyeglass temple labeling device, which is cumbersome in fixing the temples, lacks continuity between fixing mechanisms, increases the manual intervention link, and may further affect the fixing effect due to improper timing or force of manual operation.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a labeling device for applying UP stickers to the temples of eyeglasses is designed, including a worktable and an adjusting block. A rotating seat is rotatably connected to the side wall of the adjusting block, and a pressure frame is fixedly connected to the outer side wall of the rotating seat. A storage groove is provided inside the adjusting block, and a stop block is slidably connected inside the storage groove. A No. 1 spring is fixedly connected between the stop block and the inner side wall of the storage groove. Both ends of the storage groove are connected to the outside, and a sliding frame is fixedly connected to the outer side wall of the adjusting block below the storage groove.

[0006] In this solution, when the temples are placed, simply bringing the left and right adjustment blocks closer together will keep the temples in the central labeling area. At the same time, the abutment block will be automatically pushed back into the storage slot, simultaneously releasing the limit on the rotating seat. This allows the pressure frame to press against the temples from above, achieving automatic completion of the pressing action without the need for manual adjustment. This effectively enhances the stability of the temples during labeling, preventing the temples from shaking or shifting due to excessive manual operation, and providing reliable positioning assurance for labeling.

[0007] Preferably, a slider is slidably connected to the inner side of the sliding frame, a second spring is fixedly connected between the slider and the inner side wall of the sliding frame, and a push block and a locking block are fixedly connected to the left and right side walls of the slider, respectively.

[0008] In practical applications, in the initial state, the locking block is engaged in the groove of the rotating seat under the action of the second spring, restricting the rotation of the pressure frame; when the abutment block retracts into the storage groove, it will simultaneously press down the push block, causing the slider to compress the second spring and disengage the locking block from the groove, releasing the lock on the rotating seat, ensuring that the pressure frame will only move after the temple of the glasses is accurately positioned, reducing the risk of misoperation.

[0009] Preferably, the end of the locking block facing the rotating seat is located inside the groove on the surface of the rotating seat, and a pull block is rotatably connected to the side wall of the adjusting block directly below the rotating seat. A No. 3 spring is fixedly connected between the pull block and the protrusion on the side wall of the rotating seat.

[0010] In practical applications, after the locking block disengages from the groove, the tension of the No. 3 spring will pull the rotating seat to rotate through the pull block, causing the pressure frame to automatically press against the temple of the glasses; after the labeling is completed, the locking block is allowed to re-engage into the groove of the rotating seat to prepare for the next operation.

[0011] Preferably, the surface of the rotating seat is provided with a plurality of helical teeth, and a limit hook is fixedly connected to the side wall of the adjusting block directly above the rotating seat, with the bottom end of the limit hook located between the helical teeth of the rotating seat.

[0012] In practical applications, when the rotating seat rotates, the helical teeth will push the limit spring hook to deform and lift. After rotating to the appropriate angle, the limit spring hook will reset and lock into the gap of the helical teeth to prevent the rotating seat from rotating in the opposite direction. This allows the pressing angle of the pressure frame to be automatically adapted according to the thickness of the temple, ensuring that temples of different specifications can be pressed tightly.

[0013] Preferably, the surface of the workbench is provided with an adjustment groove, and a first bidirectional lead screw is rotatably connected to the inner side of the adjustment groove. Two adjustment frames pass through the surface of the first bidirectional lead screw, and the adjustment frames are threadedly connected to the first bidirectional lead screw. A second bidirectional lead screw is rotatably connected inside the adjustment frames, and two adjustment blocks pass through the surface of the second bidirectional lead screw, and the adjustment blocks are threadedly connected to the second bidirectional lead screw.

[0014] In practical applications, when the No. 1 bidirectional lead screw rotates, it drives the two adjustment frames to move closer or further away from each other along the adjustment groove, thereby clamping the temples of the eyeglasses. When the No. 2 bidirectional lead screw rotates, the positive and negative threads on its surface will drive the two adjustment blocks to move closer or further away from each other along the adjustment frame, thereby selecting the clamping position and flexibly adapting to various sizes of temples of eyeglasses.

[0015] Preferably, a support block is fixedly connected to the side of the adjustment block facing the center of the workbench, and a slot is provided on the surface of the adjustment block on the horizontal side of the support block. The support blocks and slots on the left and right surfaces of the adjustment blocks are alternately arranged, and the cross-sectional dimensions of the support block and the slot are the same.

[0016] In practical applications, when the left and right adjustment blocks are brought close together, the left support block will embed into the right slot, and the right support block will embed into the left slot, forming an interlocking structure that provides a stable support base for labeling and increases the stability of the left and right adjustment blocks.

[0017] Preferably, a stop block is fixedly connected to the workbench surface at the edge of the adjustment groove, and the distance from the stop block to the adjustment frames on the left and right sides is equal.

[0018] In practical applications, the stop block can block one end of the temple of the glasses, thereby working with the left and right adjustment blocks to complete the clamping and improve the clamping stability.

[0019] Preferably, the top of the push block is at the same height as the abutment block, and the abutment block is located above the support block and the slot.

[0020] In practical applications, the heights of the push block and the stop block are matched to ensure that the stop block can accurately contact and push the push block when it retracts, and to ensure that the rotating seat can release the limit in time.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. This utility model, by setting a storage groove and a sliding stop block inside the adjustment block, allows the eyeglass temple to be kept in the central labeling area simply by bringing the left and right adjustment blocks closer together when the temple is placed. At the same time, the stop block is automatically pushed back into the storage groove, simultaneously releasing the limit on the rotating seat, allowing the pressure frame to press against the eyeglass temple from above, thus automatically completing the pressing action without the need for manual adjustment. This effectively enhances the stability of the eyeglass temple during labeling, avoids shaking and displacement of the eyeglass temple due to excessive manual operation, and provides reliable positioning assurance for labeling.

[0023] 2. This utility model utilizes the engagement of the limiting spring hook and the helical teeth on the surface of the rotating seat to effectively limit the reverse rotation of the pressure frame with the rotating seat, ensuring a stable and reliable pressing state. At the same time, the bidirectional screw structure allows for flexible adjustment of the position of the adjustment frame and the adjustment block, enabling it to firmly clamp eyeglass temples of different sizes, greatly improving the device's adaptability to diverse products and broadening its application range.

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0033] Example 1: A labeling device for UP stickers on eyeglass temples, see [link / reference] Figures 1 to 7 The system includes a workbench 1 and an adjusting block 7. A rotating seat 12 is rotatably connected to the side wall of the adjusting block 7. A pressure frame 14 is fixedly connected to the outer side wall of the rotating seat 12. The adjusting block 7 has a storage groove 8 inside. A stop block 9 is slidably connected inside the storage groove 8. A first spring 901 is fixedly connected between the stop block 9 and the inner side wall of the storage groove 8. The two ends of the storage groove 8 are connected to the outside. A sliding frame 10 is fixedly connected to the outer side wall of the adjusting block 7 below the storage groove 8. A slider 11 is slidably connected to the inner side of the sliding frame 10. A second spring 111 is fixedly connected between the slider 11 and the inner side wall of the sliding frame 10. A push block 112 and a locking block 113 are fixedly connected to the left and right side walls of the slider 11, respectively. The end of the locking block 113 facing the rotating seat 12 is located inside the groove on the surface of the rotating seat 12.

[0034] In the above technical solution, in the initial state, the abutment 9 partially extends out of the storage groove 8 under the elastic force of the first spring 901. At this time, the pusher 112 is not squeezed by the abutment 9, the slider 11 remains in place under the action of the second spring 111, the locking block 113 is embedded in the groove of the rotating seat 12, restricting the rotation of the rotating seat 12, and the pressure frame 14 is in the raised state. When the temple of the glasses is placed on the support block 701 and the adjustment blocks 7 on both sides are pushed closer to each other, the temple of the glasses will squeeze the abutment 9, causing it to compress the first spring 901 and retract into the storage groove 8. At the same time, the other end of the abutment 9 will extend out of the storage groove 8 and gradually move closer to the pusher 112. Until the adjusting blocks 7 on both sides clamp the temples, the abutment block 9 pushes the push block 112, which in turn drives the slider 11 to compress the second spring 111 and causes the locking block 113 to disengage from the groove of the rotating seat 12, releasing the limit on the rotating seat 12. The pressure frame 14 rotates with the rotating seat 12 and presses the temples from above. Through the cooperation of the abutment block 9 and the locking block 113, the positioning of the temples and the pressing of the pressure frame 14 are automatically triggered, eliminating the need for manual operation of the pressure frame 14, reducing manual steps. Moreover, the positioning and pressing actions are completed sequentially, avoiding the displacement of the temples due to operation delays and excessive manual operation, thus improving the stability of labeling.

[0035] Specifically, such as Figure 6 As shown, a pull block 131 is rotatably connected to the side wall of the adjusting block 7 directly below the rotating seat 12. A third spring 13 is fixedly connected between the pull block 131 and the protrusion on the side wall of the rotating seat 12. When the locking block 113 releases the limiting position on the rotating seat 12, the pulling force of the third spring 13 will drive the rotating seat 12 to rotate through the pull block 131, causing the pressure frame 14 to flip towards the temple of the glasses. After the labeling is completed, manually pulling the pull block 131 can stretch the third spring 13, causing the rotating seat 12 to rotate counterclockwise and lift the pressure frame 14. At this time, the locking block 113 is re-embedded into the groove of the rotating seat 12 under the action of the second spring 111, completing the reset. The operation is convenient and improves the recycling efficiency of the device.

[0036] In one optional embodiment, a support block 701 is fixedly connected to the side of the adjustment block 7 facing the center of the worktable 1. The surface of the adjustment block 7 on the horizontal side of the support block 701 is provided with a slot 702, and the support blocks 701 and slots 702 on the surfaces of the left and right adjustment blocks 7 are alternately arranged. The top of the push block 112 is at the same height as the abutment block 9, and the abutment block 9 is located above the support block 701 and the slot 702. The cross-section of the support block 701 is the same size as the cross-section of the slot 702.

[0037] In this technical solution, when the left and right adjustment blocks 7 approach each other, the support block 701 of the left adjustment block 7 will be embedded in the slot 702 of the right adjustment block 7, and the support block 701 of the right adjustment block 7 will be embedded in the slot 702 of the left adjustment block 7, forming an interlocking structure to jointly support the temple of the glasses. At the same time, the abutment block 9 is located above the support block 701 and the slot 702, ensuring that the abutment block 9 can be accurately squeezed after the temple of the glasses is placed, triggering the subsequent pressing action.

[0038] Furthermore, such as Figure 6 As shown, the surface of the rotating seat 12 is provided with several helical teeth 121. The side wall of the adjusting block 7 directly above the rotating seat 12 is fixedly connected to a limiting hook 15. The bottom end of the limiting hook 15 is located between the helical teeth 121 of the rotating seat 12. When the rotating seat 12 rotates under the tension of the No. 3 spring 13, the helical teeth 121 will pass through the bottom end of the limiting hook 15 and temporarily deform and lift it. After rotating to the corresponding angle, the limiting hook 15 will reset under its own elastic force and lock into the adjacent helical teeth 121, preventing the rotating seat 12 from rotating counterclockwise, thereby locking the pressing angle of the pressure frame 14 and preventing it from loosening due to external force or vibration during the labeling process, ensuring a stable pressing state. If it is necessary to adjust the angle of the pressure frame 14, manually lift the limiting hook 15 to disengage it from the helical teeth 121, and then the rotating seat 12 can be rotated.

[0039] It is worth noting that the surface of the worktable 1 is provided with an adjustment groove 3. The inner side of the adjustment groove 3 is rotatably connected to a first bidirectional lead screw 4. Two adjustment frames 5 pass through the surface of the first bidirectional lead screw 4. The adjustment frames 5 are threadedly connected to the first bidirectional lead screw 4. The inner side of the adjustment frames 5 is rotatably connected to a second bidirectional lead screw 6. Two adjustment blocks 7 pass through the surface of the second bidirectional lead screw 6. The adjustment blocks 7 are threadedly connected to the second bidirectional lead screw 6. When the first bidirectional lead screw 4 is rotated, the positive and negative threads on its surface will drive the two adjustment frames 5 to move closer or further away from each other along the adjustment groove 3, thereby clamping the temples of the eyeglasses. When the second bidirectional lead screw 6 is rotated, the positive and negative threads on its surface will drive the two adjustment blocks 7 to move closer or further away from each other along the adjustment frames 5, thereby selecting the clamping position and flexibly adapting to various specifications of temples of eyeglasses, greatly improving the applicability of the device.

[0040] It is worth noting that, such as Figure 5 As shown, a stop block 16 is fixedly connected to the surface of the worktable 1 at the edge of the adjustment groove 3. The distance from the stop block 16 to the adjustment frames 5 on the left and right sides is equal. The stop block 16 can block one end of the temple of the glasses, thereby cooperating with the left and right adjustment blocks 7 to complete the clamping and improve the clamping stability.

[0041] It is worth mentioning that the top of the workbench 1 is also equipped with an electric slide rail 2. The slide of the electric slide rail 2 is fixedly connected to the labeling machine 201. The electric slide rail 2 can drive the labeling machine 201 to move precisely in the horizontal direction. After the temple of the eyeglasses is fixed, the labeling machine 201 moves to the labeling position under the drive of the electric slide rail 2, and then performs the labeling operation on the temple of the eyeglasses below under the drive of the electric push rod. It should be noted that the main structure of the labeling machine 201 includes an unwinding roller, a guide roller, a peeling plate, a pressure roller, and a drive assembly. The unwinding roller is used to place the roll of UP labeling material. Under the action of the drive assembly, the roll of material is conveyed to the peeling plate by the guide roller. The UP sticker separates from the backing paper under the sharp angle of the peeling plate, and the separated UP sticker is conveyed to the bottom of the labeling roller. After the temple of the eyeglasses is positioned and fixed, the electric slide rail 2 drives the labeling machine 201 to move to the labeling position. The labeling roller presses the UP sticker onto the preset position of the temple of the eyeglasses. Then the backing paper is wound up and recycled by another set of guide rollers to complete one labeling action. This utility model mainly describes the fixing method of the temple of the eyeglasses. Since the core structure and labeling process of the labeling machine 201 are existing mature technologies, those skilled in the art can install and use it according to the existing equipment. The specific drive control method, transmission details, etc. will not be described in detail here.

[0042] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

[0043] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
