Description

Technical Field

[0001] This utility model relates to the field of screw gluing equipment technology, and in particular to an automated screw rotary gluing mechanism. Background Technology

[0002] Currently, various models of screw gluing equipment are available on the market, mainly focusing on fully automated machines. While these machines offer a high degree of automation, their cost is also high. They are relatively inefficient for single-station operations and small-batch production, resulting in poor cost-effectiveness, complex operation, and high maintenance costs. Some traditional gluing equipment lacks adaptability and struggles to quickly switch between gluing different screw sizes. Furthermore, to ensure center alignment of the screws during gluing, manual installation and removal are still required. For screws requiring rapid gluing, manual installation is not only inefficient but also makes it difficult to guarantee the uniformity and consistency of the gluing, failing to meet the demands of industrial production. Utility Model Content

This invention primarily utilizes a preamplifier to detect parameters such as screw length and diameter. Under the action of a linear guide rail mechanism, the clamping distance of the adhesive application mechanism is automatically adjusted, thereby clamping screws of different sizes through the upper and lower rotating centers and ensuring precise adhesive application positioning.

[0011] 3. The automated screw rotary gluing mechanism provided by this utility model will trigger the sensor in front of the sheet metal part of the sensing device to send a signal to the system when the screw to be glued moves to a certain distance from the detection block in the sensing system, so that the screw has reached the designated position, thereby enabling the upper rotating tip and the lower tip to stably support the screw.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] This utility model provides an automated screw rotary adhesive application mechanism, comprising: an upper rotating shaft 1, an adhesive application mechanism fixture 2, an upper rotating center 3, a preamplifier 4, a linear guide rail mechanism 5, a large sheet metal part 6, a small sheet metal part 7, a front-end cylinder connecting plate 8, a rear-end sheet metal positioning plate 9, a detection block 10, a sensor sheet metal part 11, a photoelectric sensor 12, a lower rotating shaft mechanism 13, a lower center 14, a servo motor 15, a servo fixing plate 16, a synchronous belt mechanism 17, a cylinder lifting mechanism 18, and a cylinder pushing plate 19.

[0025] The servo motor 15, as the main driving component, is fixedly mounted on the servo mounting plate 16. It is connected to the upper rotating shaft 1 of the glue-applying mechanism via a synchronous belt mechanism 17, transmitting the motor's rotation to the upper rotating shaft 1, causing it to rotate at a set speed and direction. One end of the upper rotating shaft 1 is fixedly connected to the glue-applying mechanism fixture 2, and the other end is fitted with an upper rotating tip 3. The upper rotating shaft 1 drives the upper rotating tip 3 to rotate together, allowing the screw to rotate during the glue application process. A probe block 10 is installed behind the glue-applying mechanism fixture 2. Above the probe block 10, a sensor sheet metal part 11 connects to a photoelectric sensor 12, forming a sensing system used to detect the screw's position and accuracy. A large, recessed sheet metal part 6 is installed on the probe block 10, serving as a protective outer shell and forming a channel to guide the glue-applying screw along a predetermined path, ensuring accurate glue application. A linear guide rail mechanism 5 is installed below the glue application mechanism. The linear guide rail mechanism 5 includes a slide table, which is bolted to the rear sheet metal positioning plate 9. A preamplifier 4 is clamped between the front cylinder connecting plate 8 and the rear sheet metal positioning plate 9. A lower rotating shaft mechanism 13 is tightly connected to the front cylinder connecting plate 8 by bolts. Driven by the linear guide rail mechanism 5, the entire assembly forms a sliding fit. The lower rotating shaft mechanism 13 has a lower tip 14 at its top, which engages vertically with the upper rotating shaft 1 to provide stable support for the screw. The screw to be glued is clamped between the upper rotating tip 3 and the lower tip 14. A circular groove 311 is provided on the upper rotating tip 3 near the lower tip 14, and the screw is placed in the circular groove 311. Simultaneously, when the preamplifier 4 detects a screw signal, it controls the lower rotating shaft mechanism 13 to move precisely in the linear direction, automatically adjusting the clamping distance of the screw in the glue application mechanism. A small sheet metal part 7 is fixedly installed on the left side of the linear guide rail mechanism 5 by screws. It serves as an auxiliary guide and protective component, and cooperates with the large sheet metal part 6 to prevent dust and debris from entering the device when the screw to be glued moves along the predetermined path, thus avoiding damage to the component and affecting its performance. The cylinder lifting mechanism 18 is installed on the front cylinder connecting plate 8. The output end of the cylinder lifting mechanism 18 is connected to one end of the cylinder push plate 19. The other end of the cylinder push plate 19 has a through hole. The top of the upper rotating tip 3 is located in the through hole, and the lower tip 14 protrudes from the through hole.

[0026] The working principle of this utility model: First, the screw to be coated with glue is placed into the circular groove 311 of the upper rotating tip 3 driven by the upper rotating shaft 1 of the glue coating mechanism, providing an upper support point for the screw and ensuring that the screw maintains an accurate axial position during rotation. Then, the preamplifier 4 detects parameters such as the screw length and diameter, and under the action of the linear guide rail mechanism 5, automatically adjusts the clamping distance of the glue coating mechanism so that the mating distance between the lower tip 14 on the lower rotating shaft mechanism 13 and the upper rotating tip 3 can jointly support the screw component to be coated with glue, ensuring that the screw axis coincides with the processing axis or glue coating path axis of the equipment. The detection function of the preamplifier 4 facilitates the adaptation of screws of different sizes, ensuring accurate glue coating position. During this process, the large sheet metal part 6 and the small sheet metal part 7 of the glue coating mechanism act as a shell, protecting the internal mechanical components and preventing damage or impact on the components. At the same time, the groove-shaped channel or guide rail is designed to guide the screw to be coated with glue along the predetermined path, ensuring the accuracy and consistency of the glue coating position.

[0027] Secondly, when the screw to be coated moves to a certain distance from the detector block 10 in the sensing system, the sensor 12 in front of the sheet metal part 11 will be triggered to send a signal to the system, informing that the screw has reached the designated position and that the lower tip 14 on the upper rotating tip 3 and the lower rotating shaft mechanism 13 can stably support it. At this time, the servo motor 15 fixed on the servo fixing plate 16 is started by the control system (existing control system). Under the transmission of the synchronous belt mechanism 17, the servo motor 15 provides rotational power to the screw, so that the screw can rotate synchronously, coaxially, and concentrically under the clamping of the upper rotating tip 3 and the lower tip 14 at the set speed, so as to meet the requirements of workpiece rotation during the coating process. At the same time, the control system will start the coating device according to the preset parameters. The adhesive is sprayed from the nozzle and evenly coated on the threaded part of the rotating screw under the action of the guide plate, ensuring the uniformity of the coating. During the adhesive application process, the sensing system can monitor the process in real time. If necessary, the control system can adjust parameters such as rotation speed, amount of adhesive applied, and application time in real time to achieve the best adhesive application effect.

[0028] Finally, after the glue application is completed, the equipment will stop automatically, and the lower tip 14 will disengage the screw. If the lower tip 14 becomes worn and difficult to disengage, the screw can also be automatically disengaged by the cylinder push plate 19 of the cylinder lifting mechanism 18, thus completing the automated rotary glue application process for small batches of screws in industrial production.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
