Description

Technical Field

[0001] This utility model relates to the field of screw anti-loosening adhesive application technology, and in particular to a screw anti-loosening adhesive application device. Background Technology

[0002] In the traditional production process of screw anti-loosening treatment, operators typically rely on handheld dispensing equipment to coat each screw individually. This method is not only labor-intensive, but more importantly, its efficiency is entirely limited by the operator's skill level and physical strength, making it difficult to achieve a continuous and stable work rhythm. Therefore, overall production efficiency is low, which has become a significant bottleneck in large-scale manufacturing. At the same time, the non-repeatable nature of manual operation can easily lead to problems such as inaccurate dispensing position and uneven glue application, directly affecting the reliability and consistency of the product.

[0003] To overcome the efficiency bottleneck of manual dispensing, automated dispensing or spraying devices have emerged in existing technologies. These devices typically orient screws using a feeding mechanism such as a vibratory feeder and transport them to the dispensing station, where a fixed or simply moving nozzle automatically sprays adhesive onto the screw threads. By controlling the dispensing volume and time through a pre-programmed sequence, mechanized operation replaces manual labor, enabling continuous dispensing and thus processing more screws per unit time. This significantly improves production efficiency while reducing quality fluctuations caused by human fatigue.

[0004] However, the aforementioned automated dispensing technology has also revealed new technical problems during its widespread application. Firstly, when dealing with screws of different specifications and diameters, frequent adjustments to the nozzle height and horizontal position are required to ensure accurate dispensing. Most devices use simple screw lifting or bolt locking structures for adjustment, a time-consuming and labor-intensive process that severely restricts the speed of production line changeovers and affects the overall utilization rate and flexible production capabilities of the equipment. Secondly, due to overspray, scattering, and natural dripping of adhesive during the spraying process, a large amount of adhesive does not effectively adhere to the screws but drips onto the equipment table and even the ground. This not only wastes adhesive and increases production costs but also requires additional manpower and time for cleaning and maintenance; otherwise, accumulated residual adhesive will interfere with the normal operation of the equipment. The root cause lies in the lack of a mechanical structure capable of precisely and quickly adjusting the nozzle position, and an integrated system for effectively collecting and recovering residual adhesive. Utility Model Content

[0005] The purpose of this utility model is to provide a screw anti-loosening dispensing device, which solves the technical problems of cumbersome and time-consuming nozzle position adjustment process in existing automated dispensing equipment, as well as waste and environmental pollution caused by excessive glue splashing and dripping during the dispensing process.

[0006] To achieve the above objectives, this utility model provides a screw anti-loosening adhesive dispensing device, including a support platform. The top of the support platform has a groove, and the bottom surface of the groove is inclined. A baffle is fixedly installed at the lowest point of the inclined bottom surface of the groove on the support platform. The baffle is provided with a drawer / exhaust connector. Two sets of threaded holes are symmetrically opened on both sides of the support platform and extend into the groove. Each set of threaded holes has three or more threads. Threaded cylinders are installed in the threaded holes through threads. A nozzle is fixedly installed at one end of the threaded cylinder located in the groove. A limit nut is installed on the outside of the threaded cylinder through threads. A pipe connector is fixedly installed at the end of the threaded cylinder opposite to the nozzle.

[0007] The support platform has fixed plates on both sides of its bottom end, and several diagonal bracing plates are installed at intervals at the angle between the support platform and the fixed plates.

[0008] The fixing plate has several fixing holes spaced apart between the diagonal braces. Bolts pass through the fixing holes and are connected to the external support structure by threads to form a fixing.

[0009] The top of the support platform is fitted with assembly plates on both sides of the groove. The assembly plates are fixed to the support platform by several bolts, and the bolt fixing points of the assembly plates are respectively set as adjustment grooves.

[0010] The assembly plate has a clamping plate fixedly installed on one side of its top, and a conveying roller is installed inside the clamping plate through a bearing. A conveying track is movably installed on the outside of the conveying roller.

[0011] One end of each of the conveying rollers is connected to the output shaft of the conveying motor, and the conveying motors are respectively mounted on one side of the top of the clamping plate by bolts.

[0012] This utility model discloses a screw anti-loosening adhesive dispensing device. Through a support platform and an inclined groove structure at its top, along with a baffle and extraction connector at the lowest point of the groove, it provides a foundation for collecting and processing excess adhesive generated during the dispensing process. Multiple sets of threaded holes symmetrically located on both sides of the support platform allow the threaded cylinder to be screwed in or out, thus flexibly adjusting the height and horizontal distance of its end nozzle relative to the screw being processed. A limiting nut on the outside of the threaded cylinder locks its position after adjustment, preventing displacement during operation and ensuring the stability and consistency of the dispensing position. A pipe connector at the end of the threaded cylinder facilitates connection to external adhesive supply or cooling equipment.

[0013] To further enhance the adaptability and stability of the device, the bottom of the support platform is reinforced with a fixing plate and diagonal bracing to strengthen the overall structural rigidity. The fixing holes on the fixing plate facilitate the secure installation of the device onto the external support structure. Conveying components are mounted on both sides of the top of the support platform via assembly plates. The adjustment grooves on the assembly plates allow for flexible adjustment of the spacing between the two conveyor belts according to the screw diameter, ensuring that screws of different sizes can be stably clamped and conveyed. The conveyor motor drives the conveyor rollers, which in turn rotate the conveyor belts, enabling continuous automated movement of the screws. As the screws pass over the grooves, their threads are sequentially treated with adhesive spraying and cooling.

[0014] This device, through the combination of an adjustable nozzle structure and an integrated residual adhesive recovery system, enables efficient and continuous dispensing operations while adapting to the processing needs of screws of different specifications. It also helps reduce adhesive waste and maintain a clean working environment. Attached Figure Description

Detailed Implementation

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figures 1-4 .

[0023] This utility model provides a screw anti-loosening adhesive dispensing device, including a support platform 101. A groove 102 is formed at the top of the support platform 101, and the bottom surface of the groove 102 is inclined to facilitate liquid flow. A baffle 103 is fixedly installed at the lowest point of the inclined bottom surface of the groove 102 on the support platform 101. A suction / discharge connector 104 is provided on the baffle 103 for connecting to an external suction device to discharge the collected adhesive. Two sets of threaded holes 105 are symmetrically formed on both sides of the support platform 101, each set of threaded holes 105 covering... It contains three or more holes that extend into the interior of the groove 102; a threaded cylinder 106 is installed in the threaded hole 105 by means of threads, and a nozzle 107 is fixedly installed at one end of the threaded cylinder 106 located in the groove 102 for spraying adhesive or cooling medium toward the screw; a limit nut 108 is installed on the outside of the threaded cylinder 106 by means of threads for locking the position of the threaded cylinder 106 after adjustment; a pipe connector 109 is fixedly installed at the end of the threaded cylinder 106 opposite to the nozzle 107 for connecting to an external adhesive supply or cooling device.

[0024] Fixing plates 110 are fixedly installed on both sides of the bottom end of the support platform 101 to provide overall installation support; several diagonal bracing plates 111 are installed at intervals at the connection angle between the support platform 101 and the fixing plates 110 to enhance structural stability and vibration resistance; several fixing holes 112 are opened at intervals between the diagonal bracing plates 111 on the fixing plates 110, bolts are inserted into the fixing holes 112 and connected to the external support structure by threads to achieve reliable fixation of the entire device.

[0025] Assembly plates 113 are respectively attached to both sides of the top of the support platform 101 in the groove 102. The assembly plates 113 are fixed to the support platform 101 by several bolts. Adjustment grooves 114 are opened at the bolt fixing points of the assembly plates 113. By loosening the bolts, the lateral position of the assembly plates 113 can be adjusted to accommodate screws of different specifications. Clamping plates 115 are respectively fixedly installed on one side of the top of the assembly plates 113. Conveying rollers 116 are installed inside the clamping plates 115 through bearings. Conveying tracks 117 are movably installed on the outside of the conveying rollers 116. The two conveying tracks 117 are arranged opposite each other to clamp and convey screws. One end of the conveying rollers 116 is connected to the output shaft of the conveying motor 118. The conveying motor 118 is respectively installed on one side of the top of the clamping plate 115 by bolts to provide power to move the conveying tracks 117.

[0026] In this embodiment, the device drives the conveyor roller 116 and the conveyor belt 117 to move the screws by the conveyor motor 118. When the screws pass over the groove 102, the nozzle 107 performs dispensing and cooling. The groove 102 collects the excess glue and discharges it through the extraction connector 104. The overall structure works together to achieve efficient, stable and clean operation of screw anti-loosening treatment.

[0027] Working principle: Two conveyor motors 118 are started respectively, driving the connected conveyor rollers 116 to rotate. The conveyor rollers 116 drive the conveyor belts 117 sleeved on their outer sides to rotate in a cycle. Since the conveying surfaces of the two conveyor belts 117 are arranged opposite to each other, an adjustable clamping conveying channel is formed. When the upstream screw screening device feeds the screw into the two conveyor belts 117, the screw is clamped and moves forward smoothly with the rotation of the belt. During this conveying process, the screw part, that is, the threaded area that needs to be glued, is exposed in the groove 102 at the top of the support platform 101.

[0028] To accommodate the conveying of screws of different specifications, the device is designed with an adjustable mounting structure. The assembly plate 113 is connected to the top of the support platform 101 by bolts, and the bolts pass through the adjustment grooves 114 opened on the assembly plate 113. When the bolts are loosened, the operator can move the assembly plate 113, thereby changing the relative distance between the two conveyor tracks 117, so as to achieve stable clamping and conveying of screws of different diameters. After the adjustment is completed, the bolts are tightened to lock the position, ensuring the versatility and flexibility of the device.

[0029] When the screw is conveyed to the predetermined position above the groove 102, the dispensing process begins. The support platform 101 has multiple sets of threaded holes 105 symmetrically opened on both sides of the groove 102. Each set contains three or more threaded holes 105, and the hole positions on both sides correspond to each other. The threaded cylinder 106 is screwed into these threaded holes 105 by thread. The distance between the nozzle 107 installed at its end and the threaded part of the screw below can be precisely adjusted by the screwing depth to ensure the accuracy of the dispensing position. After adjustment, the limiting nut 108 on the outside of the threaded cylinder 106 is tightened to make it fit tightly against the wall of the support platform 101, thereby effectively locking the threaded cylinder 106 and preventing it from shifting due to vibration during operation, thus ensuring the stability and repeatability of dispensing.

[0030] These nozzles 107 are connected to external equipment via a threaded cylinder 106 and a pipe joint 109. Specifically, the nozzle 107 located above the lowest point of the inclined bottom surface of the groove 102 has its pipe joint 109 connected to an adhesive storage and supply device via a hose, and is responsible for spraying a fixed amount of anti-loosening adhesive onto the moving screw thread.

[0031] During the dispensing process, excess adhesive inevitably drips. Since the bottom surface of the groove 102 is designed to be inclined, the dripping adhesive will automatically flow along the inclined surface and collect at the lowest point of the groove 102. A baffle 103 is fixedly installed at this point. The suction and discharge connector 104 on the baffle 103 can be connected to an external suction pump to continuously extract and recycle the waste adhesive collected here, which not only keeps the work area clean but also avoids waste of adhesive and pollution to the environment.

[0032] The screws that have been glued continue to move forward with the conveyor belt 117 and reach the work station located above the highest point of the inclined bottom surface of the groove 102. At this position, another set of nozzles 107 has pipe joints 109 connected to the air-cooling device, which blows cooling airflow onto the glued screws to accelerate the initial curing and shaping of the glue, thereby initially achieving the anti-loosening effect and laying the foundation for subsequent complete curing.

[0033] The stability of the entire device is ensured by its supporting structure. The fixing plates 110 fixedly installed on both sides of the bottom end of the support platform 101 can be used to firmly install the entire device onto the external supporting structure, such as a workbench or frame, through the fixing holes 112 on them. In order to further enhance the structural rigidity, several diagonal bracing plates 111 are also installed at intervals at the connection angle between the support platform 101 and the fixing plates 110, which effectively prevents vibration or deformation that may occur during the operation of the device and ensures the reliability of long-term operation.

[0034] In summary, this device achieves fully automated continuous processing of screws from conveying, positioning, precise dispensing, residual glue recovery, to initial cooling and curing through the orderly and coordinated operation of the conveying system, adjustable dispensing system, glue collection and recovery system, and cooling system. This greatly improves the efficiency, consistency, and quality of screw anti-loosening treatment, while also taking into account operational flexibility and environmental friendliness.

[0035] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
