Description

Technical Field

[0001] This utility model relates to a lens assembly module and belongs to the field of lens circuit board assembly technology. Background Technology

[0002] After industrial lenses are assembled on the corresponding control boards, they need to be glued to ensure a firm connection between the components, and then the final fixing is completed by screw fastening. In traditional lens assembly lines, the lens is usually glued and screws are tightened manually, but this method is inefficient and cannot meet daily processing needs. If relevant functional components are used to replace manual labor, it is difficult to control the accuracy of glue position and amount during glue dispensing. In particular, after the glue dispensing or spraying action is completed, glue residue is easy to leave at the glue dispensing head. This hardened residue may accumulate and fall on the surface of the installation position, affecting the normal operation of glue dispensing or coating, and easily producing assembly failures. This not only wastes production costs but also affects the yield of automated production. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a lens assembly module for automatically dispensing glue and tightening screws on the lens assembly plate. It can prevent residual glue from affecting the normal glue application to a certain extent, and can perform position calibration each time it works to avoid glue position deviation caused by repeated actions. It has good precision and stability.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] This utility model provides a lens assembly module, including a movable module and a movable plate. The movable module is used to drive the movable plate to move between a processing area and a material preparation area. An electric screwdriver and a glue supply mechanism are installed on the movable plate. The material preparation area is provided with a glue dispensing head processing mechanism and a screw feeder. The glue dispensing head processing mechanism includes a bracket, on which a correction tube and a glue head cleaning assembly are installed. The correction tube has a correction hole above it that matches the shape of the glue dispensing head of the glue supply mechanism. The glue head cleaning assembly includes a negative pressure generating device and an air extraction tube. The air extraction tube is used to clean residual glue at the end of the glue head.

[0006] Specifically, the glue head cleaning assembly also includes a placement box mounted on a bracket. The placement box has a sealing plate, and the sealing plate has an insertion hole in the middle that can match the glue head. The suction pipe is connected to the upper part of the interior of the placement box.

[0007] Specifically, the placement box contains a disposable cup, the height of which is lower than the height of the inner cavity of the placement box, and the opening of the disposable cup corresponds to the position of the insertion hole.

[0008] Specifically, the dispensing head processing mechanism also includes a lifting drive mechanism for driving the support to rise, and the correction hole is provided with a supporting part for supporting the dispensing mechanism.

[0009] Specifically, the bracket is also equipped with a collection cylinder, and the wall of the collection cylinder is provided with a wiping component for wiping the dispensing head.

[0010] Specifically, the wiping assembly includes an air supply pipe and an air supply nozzle, wherein the air supply nozzle is installed inside the collection cylinder and the air blowing direction is downward.

[0011] Specifically, the material preparation area is also equipped with a torque detection module, which is located at the feeding end of the screw feeder.

[0012] Specifically, a weighing device is also provided between the screw feeder and the dispensing head processing mechanism, and the weighing device is used to measure the mass of the glue dots.

[0013] Specifically, the upper surface of the weighing device is covered with a film strip, which is supplied to the winding device by a feeding device. When the film strip is tightened, it can provide downward pressure to the weighing device.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0015] This invention enables automatic screw fastening and dispensing by setting up a moving module to synchronously move an electric screwdriver and a glue supply mechanism. Both can use the same module braking, effectively saving the number of drives and reducing costs. At the same time, the device provides a correction tube to correct the position of the glue dispensing mechanism, ensuring that it can move to the "zero" position after repeated actions, which can avoid the accumulation of movement errors and improve the glue dispensing position accuracy. In addition, the device is equipped with an additional air extraction tube to absorb residual glue at the end of the glue dispensing head, which can avoid problems such as excessive glue or hardened residual glue at the end causing poor glue supply, thereby improving glue supply quality and increasing the yield of automated production assembly.

[0022] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0023] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example:

[0025] This utility model provides a lens assembly module for automatically dispensing glue and tightening screws on a lens assembly plate. It can prevent residual glue from affecting the normal glue application process to a certain extent, and can perform position calibration during each operation to avoid glue dispensing position deviations caused by repetitive actions. It has good accuracy and stability. To realize the structural functions of the module, it includes a moving module 1 and a movable plate 2. The moving module 1 drives the movable plate 2 to move between the processing area and the material preparation area, including but not limited to vertical and horizontal movement. The composition of the moving module 1 is not limited here, as long as it meets the processing requirements. The movable plate 2 is then mounted with... Equipped with an electric screwdriver 3 and a glue supply mechanism 4, it is used to automatically tighten screws and automatically supply glue for bonding, respectively. Since both are mounted on the movable plate 2, the screw tightening action can be performed immediately after the glue supply action is completed. This not only saves on the drive mechanism but also simplifies the movement conflicts of modules under complex tooling, thus saving processing time. In the material preparation area, there is a glue dispensing head processing mechanism 5 and a screw feeder 6. The screw feeder 6 can adopt existing screw feeding methods, and its specific shape and model are not limited here. It is used to supply screws to be installed to the electric screwdriver 3. To ensure the glue dispensing effect, the glue dispensing head processing mechanism 5 includes a bracket 501, which can be referred to as... Figure 4 and Figure 5 As shown, a correction tube 502 and a glue head cleaning assembly are installed on the bracket 501. Specifically, the correction tube 502 has a correction hole on its upper part that matches the shape of the glue head of the glue supply mechanism 4. This correction hole is used to guide the position of the glue head after it is matched with the glue head, and the position is set as a reference position by the automatic controller. This can ensure that the accuracy of each action can meet the glue dispensing requirements and avoid the position deviation caused by long-term action from affecting the actual glue dispensing effect. In order to ensure that the size, shape and quality of the glue dot meet the requirements, the residual glue at the glue head position needs to be cleaned at least periodically. The glue head cleaning assembly includes a negative pressure generating device 508 and an air extraction tube 509. The negative pressure of the air extraction tube 509 can clean the residual glue at the end of the glue head. The specific function of the air extraction tube 509 is not limited here. Other specific implementation methods can be referred to in the following text.

[0026] This utility model provides a lens assembly module, specifically offering a method for cleaning residual adhesive using an air extraction tube 509. Specifically, the adhesive head cleaning assembly includes a placement box 504 mounted on a bracket 501, with a sealing plate 503 on the placement box 504. The sealing plate 503 has a central insertion hole that matches the adhesive dispensing head, and the air extraction tube 509 connects to the upper part of the placement box 504. (See reference...) Figure 3As shown, after the dispensing head is inserted into the hole in the middle of the sealing plate 503, air is drawn out by the air extraction pipe 509, creating a negative pressure inside the placement box 504. By drawing out the air from the nozzle and the gas around the nozzle, the nearby adhesive dots are driven out, ultimately achieving the technical effect of removing residual adhesive. To avoid the difficulty of cleaning residual adhesive inside the placement box 504, a disposable cup 505 can also be provided inside the placement box 504, such as... Figure 3 As shown, the height of the disposable cup 505 is lower than the height of the inner cavity of the placement box 504 to prevent the suction tube 509 from failing to draw negative pressure properly inside the cup. At the same time, the opening of the disposable cup 505 is positioned to correspond to the position of the insertion hole, so that when negative pressure occurs and residual adhesive falls, it can fall directly into the disposable cup 505. By removing the sealing plate 503, the disposable cup 505 can be taken out, and the residual adhesive inside can be easily cleaned.

[0027] The lens assembly module provided in this embodiment of the utility model has a screw fastening mechanism that needs to be frequently raised and lowered. Therefore, long-term movement in the vertical direction may lead to the accumulation of motion errors. In order to facilitate the provision of a vertical position reference, the dispensing head processing mechanism 5 can be provided, which also includes a lifting drive mechanism 507 for driving the bracket 501 to rise. It is used to lift the correction tube 502 to a designated position to position the end of the dispensing head. In order to properly support the dispensing mechanism without damaging the end of the dispensing mechanism, the correction hole needs to be provided with a supporting part for supporting the dispensing mechanism 4. This can be achieved by restricting the shape of the hole.

[0028] This utility model provides a lens assembly module. Considering that long-term residue of adhesive at the edges may lead to localized hardening and accumulation of adhesive dots, a collection cylinder 506 can be installed on the bracket 501 to remove such residue effectively and promptly. The wall of the collection cylinder 506 is provided with a wiping component for wiping the adhesive dots, such as a wiping cloth, to physically wipe the outer surface using mechanical motion. In some other embodiments, the wiping component may include an air supply pipe and an air supply nozzle. Specifically, the air supply nozzle is installed inside the collection cylinder 506 and the air blowing direction is downward to prevent residual adhesive from being blown out of the collection cylinder 506 and affecting the equipment and the surrounding working environment.

[0029] In some embodiments of the lens assembly module provided by this utility model, in order to detect whether the torque of the electric screwdriver 3 is normal before automatically tightening the screw, a torque detection module 7 can be provided in the material preparation area. In order to simplify the operation mode of the electric screwdriver 3, the torque detection module 7 can be directly set at the feeding end of the screw feeder 6, and the detection can be completed before picking up the material.

[0030] This utility model provides a lens assembly module. To facilitate the determination of whether the dispensing head position has been properly cleaned and to pre-test whether the glue spraying before application meets the ideal requirements, a weighing device 8 can be provided between the screw feeder 6 and the dispensing head processing mechanism 5. Specifically, the weighing device 8 is used to measure the mass of the glue dots. Before the actual dispensing operation, several glue dots are pre-applied to the weighing device 8, and the mass of the glue dots is weighed to determine whether the glue dots meet the preset requirements. If they do not meet the requirements, the dispensing head position can be cleaned again, or glue can be continuously applied to observe whether it meets the requirements. If the mass still does not meet the preset requirements after multiple applications, an alarm needs to be triggered for inspection or repair to avoid affecting the normal assembly and production of the lens. To prevent adhesive dots from accumulating on the weighing device 8, a film strip (not shown in the figure) can be applied to the upper surface of the weighing device 8. This film strip is supplied to the winding device by the feeding device. When the film strip is tightened, it can provide downward pressure to the weighing device 8. After the dispensing is completed, the film strip is wound up and moved, which carries the adhesive dots back in. This can prevent the adhesive dots from accumulating on the weighing device 8 for a long time, affecting the position of the adhesive dots and the weighing accuracy. It can ensure a relatively accurate measuring range with a small volume requirement.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
