Description

Technical Field

[0001] This application relates to the technical field of positioning guide sleeve devices, and in particular to an optical film positioning guide sleeve device. Background Technology

[0002] There are many ways to classify lenses, and optical lenses are just one of them. They are mainly composed of glass and resin and are mostly used in eyeglasses and microscopes. In the production process of optical lenses, in order to improve the service life of optical lenses, they need to be coated after processing. However, the existing coating equipment cannot effectively fix and protect the lenses, causing the lenses to shift during the coating process, affecting the yield. Furthermore, when coating the other side of the lens, it is necessary to reposition the lens for coating, which affects the coating efficiency. Currently, the market announcement number CN207224478U discloses an optical welding mask lens mold, including: a fixed mold assembly, including a fixed mold base plate and a fixed mold template, the fixed mold assembly further including a fixed mold core, the fixed mold core including a first fixed mold core and a second fixed mold core housed in the first fixed mold core; a moving mold assembly, including a moving mold base plate, a pad block and a moving mold template, the moving mold template having a moving mold groove recessed from one side of the moving mold template into the interior of the moving mold template, the moving mold assembly further including an ejection device and a moving mold core housed in the moving mold groove, the moving mold core including a first moving mold core and a second moving mold core housed in the first moving mold core; and a guide assembly, including a guide post fixed on the moving mold template and a guide sleeve sleeved on the guide post and fixed to the fixed mold template.

[0003] It was found that the positioning components were constantly subjected to dry friction during actual use, which made them prone to uneven wear, causing the mold on the positioning components to become skewed and affecting the forming quality of the optical film. Utility Model Content

[0004] To solve the above-mentioned technical problems, this application provides an optical film positioning guide sleeve device, which has the advantages of reducing uneven wear and ensuring the forming quality of optical film.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: An optical film positioning guide sleeve device includes a guide sleeve and a guide post. A sliding sleeve is provided between the guide sleeve and the guide post. A plurality of balls are evenly distributed on the sliding sleeve. The two ends of the balls abut against the inner wall of the guide sleeve and the outer wall of the guide post, respectively. An adjusting element for adjusting the position of the sliding sleeve is provided on the guide sleeve.

[0006] The above technical solution achieves the goal of ensuring that when the guide post slides between the guide sleeves, it receives rolling friction from the balls in the sleeve, thus transforming the sliding friction between the guide post and the sleeve into rolling friction between the balls and the guide sleeve, and between the balls and the guide post. This reduces uneven wear caused by sliding friction, which can lead to inaccurate guidance. While converting sliding friction into rolling friction between the balls reduces friction and wear, it also transforms a large contact area into point contact between the balls and surfaces. Therefore, after prolonged up-and-down sliding, wear grooves will appear on the balls. Although uneven force reduces wear compared to direct sliding friction, uneven wear can still occur after prolonged use. Therefore, the guide sleeve is equipped with an adjusting element to adjust the position of the sleeve, thereby reducing uneven wear and ensuring the quality of the optical film forming.

[0007] As a preferred embodiment of this application, the adjusting member includes an adjusting sleeve rotatably mounted on a guide sleeve, a lever mounted on the adjusting sleeve, an upper lever mounted on the lever, and a lower lever mounted on the top of the sliding sleeve that engages with the upper lever.

[0008] To achieve the above technical solution, pressing the lever causes the upper teeth on the lever to press down and clamp the lower teeth, thus engaging the upper and lower teeth. At this time, rotating the adjusting sleeve causes the sliding sleeve to rotate, which in turn causes the ball bearings on the sliding sleeve to rotate and adjust their position. This prevents the ball bearings from moving in the same position for a long time, thereby reducing uneven wear and ensuring positioning accuracy.

[0009] As a preferred embodiment of this application, an elastic element is provided between the lever and the adjusting sleeve to move the upper lever tooth away from the lower lever tooth.

[0010] The above technical solution enables the lever to move away from the rotating sleeve under the action of the spring, thereby moving the upper lever tooth away from the sliding sleeve and thus preventing it from affecting the sliding sleeve.

[0011] As a preferred embodiment of this application, the adjusting sleeve is provided with an oil storage cavity, the inner wall of the adjusting sleeve is provided with an oil injection port communicating with the oil cavity, and the adjusting sleeve is provided with a plurality of oil outlets on the side near the sliding sleeve.

[0012] By implementing the above technical solution, lubricant can be injected into the oil outlet cavity through the oil injection port, and then discharged into the sliding sleeve from the oil outlet port to lubricate the balls, thereby converting dry friction into wet friction, thus further reducing uneven wear and ensuring the guiding effect.

[0013] As a preferred embodiment of this application, the elastic element is disposed in the oil storage cavity, and an clearance opening is provided above the lever. When the lever is pressed down, the clearance opening is aligned with the oil outlet.

[0014] The above technical solution is achieved by placing the spring in the lubrication chamber, placing the lever on one side of the oil storage chamber and fitting it against the oil outlet, and providing an clearance opening above the lever. When the lever is pressed down, the clearance opening corresponds to the oil outlet, thereby achieving the effect of oil being dispensed when the lever is pressed. In other words, when the person rotates the sliding sleeve, the sliding sleeve can be automatically lubricated, thus ensuring the lubrication effect.

[0015] In summary, this application includes at least one of the following beneficial technical effects: Even when the guide post slides between the guide sleeves, it receives rolling friction from the balls in the sleeve, thus converting the sliding friction between the guide post and the sleeve into rolling friction between the balls and the guide sleeve, and between the balls and the guide post. This reduces uneven wear caused by sliding friction, which can lead to inaccurate guidance. While converting sliding friction into rolling friction between the balls reduces friction and wear, it also transforms a large contact area into point contact between the balls and surfaces. Therefore, after prolonged up-and-down sliding, wear grooves will appear on the balls. Although uneven force reduces wear compared to direct sliding friction, uneven wear can still occur after long-term use. Therefore, the guide sleeve is equipped with an adjusting element to adjust the position of the sleeve, thereby reducing uneven wear and ensuring the quality of the optical film forming.

[0021] The following is in conjunction with the appendix Figure 1-3This application will be described in further detail.

[0022] This application discloses an optical film positioning guide sleeve device. (Refer to...) Figure 1 The optical film positioning guide sleeve device includes a guide sleeve 1 and a guide post 2. A sliding sleeve 3 is provided between the guide sleeve 1 and the guide post 2. A number of balls 4 are evenly distributed on the sliding sleeve 3. The two ends of the balls 4 abut against the inner wall of the guide sleeve 1 and the outer wall of the guide post 2, respectively. This ensures that when the guide post 2 slides between the guide sleeves 1, it receives rolling transmission from the balls 4 in the sliding sleeve 3, thereby converting the sliding friction between the guide post 2 and the sliding sleeve 3 into rolling friction between the balls 4 and the guide sleeve 1 and between the balls 4 and the guide post 2. This reduces the occurrence of uneven wear caused by sliding friction, which leads to inaccurate guidance. Meanwhile, because the sliding friction is converted into rolling friction between the balls 4, although the friction force can be reduced and the wear can be reduced, the large contact area is also converted into point contact between the balls 4 and the surface. Therefore, after sliding up and down for a long time, wear grooves will appear on the balls 4. Due to uneven force, after long-term use, although the friction is reduced compared to direct sliding friction, uneven wear will still occur. Therefore, the guide sleeve 1 is provided with an adjusting element 5 to adjust the position of the sliding sleeve 3.

[0023] The adjusting component 5 includes an adjusting sleeve 51 rotatably mounted on the guide sleeve 1. A lever 52 is mounted on the adjusting sleeve 51, and an upper lever 53 is mounted on the lever 52. A lower lever 54, which engages with the upper lever 53, is mounted on the top of the sliding sleeve 3. By pressing the lever 52, the upper lever 53 presses down on the lower lever 54, causing them to engage. Rotating the adjusting sleeve 51 rotates the sliding sleeve 3, which in turn rotates the ball bearing 4 on the sliding sleeve 3 to adjust its position. This prevents the ball bearing 4 from moving in the same position for an extended period, reducing uneven wear and ensuring accurate positioning. In this embodiment, the elastic element is a spring 55. The adjusting sleeve 51 has a slot for the lever 52 to be inserted. The spring 55 is positioned between the lever 52 and the bottom wall of the slot, causing the lever 52 to move away from the rotating sleeve under the action of the spring 55. This causes the upper lever 53 to move away from the sliding sleeve 3, preventing it from affecting the sliding sleeve 3.

[0024] The adjusting sleeve 51 is provided with an oil storage cavity 6, and an oil inlet 7 communicating with the oil cavity is provided on the inner wall of the adjusting sleeve 51. Several oil outlets 8 are provided on the side of the adjusting sleeve 51 near the sliding sleeve 3. This allows lubricant to be injected into the oil outlet cavity through the oil inlet 7, and then discharged into the sliding sleeve 3 through the oil outlets 8 to lubricate the ball bearings 4, thereby converting dry friction into wet friction, further reducing uneven wear and ensuring the guiding effect. In this application, the slot is connected to the oil inlet cavity, so that the spring 55 is located in the lubrication cavity, and the lever 52 is located on the side of the oil storage cavity 6 and fits against the oil outlet 8. An avoidance opening 56 is provided above the lever 52. When the lever 52 is pressed down, the avoidance opening 56 is aligned with the oil outlet 8, thereby achieving the effect of oil being released when the lever 52 is pressed. That is, when the person rotates the sliding sleeve 3, the sliding sleeve 3 can be automatically lubricated, thus ensuring the lubrication effect.

[0025] The implementation principle of the optical film positioning guide sleeve device in this application embodiment is as follows: When the guide post 2 slides between the guide sleeves 1, it receives rolling transmission from the balls 4 in the sliding sleeve 3, thereby converting the sliding friction between the guide post 2 and the sliding sleeve 3 into rolling friction between the balls 4 and the guide sleeve 1 and between the balls 4 and the guide post 2. This ensures that the uneven wear caused by sliding friction is reduced, thus preventing inaccurate guidance. At the same time, although converting the sliding friction into rolling friction between the balls 4 can reduce friction and thus reduce wear, it also transforms a large contact area into point contact between the balls 4 and the surface. Therefore, after long-term up-and-down sliding, wear grooves will appear on the balls 4. Due to uneven force, after long-term use, although the wear is reduced compared to direct sliding friction, uneven wear will still occur. Therefore, the guide sleeve 1 is provided with an adjusting member 5 to adjust the position of the sliding sleeve 3. That is, the adjusting member 5 lifts up to adjust the position of the sliding sleeve 3, thereby reducing uneven wear and ensuring the quality of optical film forming.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
