Description

Technical Field

[0001] The utility model relates to the technical field of fastener production equipment, in particular to a fastener precision gluing device. Background Art

[0002] Chemical glue used for fasteners and screws is usually called fastening glue or anaerobic sealant. This glue is mainly used to ensure that the screws do not fall off during operation.

[0003] The problem with the existing technology is that liquid chemical glue is applied to the threaded surface of the fastener, usually by setting a glue dripping nozzle vertically above the fastener, and using the liquid chemical glue to naturally drip onto the threaded section of the fastener to complete the glue coating process.

[0004] However, this form will cause the problem of unstable dripping area of ​​the liquid chemical glue. When the process standard requires specifying the area where the chemical glue is applied to the threaded section of the fastener, for example, the process specifies that the chemical glue is applied between a certain number of teeth, the dripping form is difficult to meet such precise requirements.

[0005] At the same time, when the chemical glue drips onto the thread, it naturally slides along the outer peripheral surface due to gravity, completing a circle of coating. This form easily causes the problem of uneven thickness of the chemical glue on the outer peripheral surface of the thread.

[0006] Therefore, it is necessary to design a fastener precision gluing equipment to overcome the above problems and improve the accuracy of the chemical glue coating area and the uniformity of the coating thickness. Utility Model Content

[0007] In order to solve the deficiencies of the above-mentioned technologies, the utility model provides a fastener precision gluing device.

[0008] The utility model is further provided with: a fastener precision gluing device, comprising a disc machine, a glue dripping mechanism, a plurality of magnetic turntables and a driving mechanism, wherein a plurality of rotating shafts are equally spaced radially on the outer circumference of the disc of the disc machine, the magnetic turntable comprising a connecting end and a magnetic end, the connecting end being axially fixed and axially rotating with the rotating shaft, and the magnetic end magnetically attracting the fastener;

[0009] The disc machine is provided with a glue dripping station, which drives the magnetic turntable to pass through the glue dripping station one by one. The driving mechanism and the glue dripping mechanism are arranged at the glue dripping station. The glue dripping mechanism outputs liquid chemical glue to the threaded section of the fastener passing through the glue dripping station. The driving mechanism contacts the magnetic turntable passing through the glue dripping station, drives the magnetic turntable to drive the fastener to axially rotate at the glue dripping station.

[0010] By adopting the above technical solution, a rotating shaft is set on the outer circumference of the disc of the disc machine, and then a magnetic turntable is set on the outer circumference of the disc. The magnetic turntable uses the connection between the connecting end and the rotating shaft to realize axial positioning and axial rotation movement. The magnetic end can be provided with a magnet, or other existing technologies, so that the magnetic end can magnetically adsorb the fastener. When the fastener is on the machine, it is coaxially arranged with the magnetic turntable, and is driven by the disc machine to pass through the glue dripping station one by one.

[0011] At the glue dispensing station, a drive mechanism contacts a magnetic turntable passing through the station, causing it to rotate axially during contact. This arrangement allows the chemical adhesive to be evenly applied to the threads of the fastener as it drips onto the fastener. As the fastener, along with the disc, exits the glue dispensing station, the magnetic turntable disengages from the drive mechanism and ceases axial rotation, facilitating subsequent drying and other processing steps.

[0012] Further configuration of the utility model: the driving mechanism includes a frame, a driving motor, a transmission belt, and a driving pulley, a tensioning pulley and several driven pulleys rotatably arranged on the frame, the several driven pulleys are arranged in parallel and are located vertically above the magnetic turntable passing through the glue dripping station, the transmission belt is sleeved on the driving pulley, the tensioning pulley and several driven pulleys, and is in friction contact with the outer peripheral surface of the magnetic turntable passing through the glue dripping station, the driving motor is linked with the driving pulley to drive the transmission belt to rotate, and drive the magnetic turntable of the glue dripping station with which the transmission belt is in friction contact to rotate around the rotating shaft.

[0013] By adopting the above technical solution, a contact area with a flat end is formed by setting several driven pulleys in parallel. The magnetic turntable enters the glue-drip station and contacts the transmission belt on the outer periphery of the driven pulley. Due to the friction force of the contact, the turntable forms an axial rotation along the direction of rotation of the transmission belt.

[0014] The utility model is further configured as follows: the outer peripheral surface of the magnetic turntable is provided with a rolling pattern, and the magnetic end of the magnetic turntable is provided with an insertion column.

[0015] The present invention is further provided with: the glue dripping mechanism includes a recovery bucket and a brush member, the recovery bucket is arranged vertically below the fastener passing through the glue dripping station, the brush member includes a clamping end, a smoothing end, a length adjustment strip, a positioning screw, an elastic friction plate and a fixing bolt, the clamping end is provided with a clamping groove, a threaded hole passing through the clamping groove, and a clamping screw, the clamping groove is adapted to the edge profile of the recovery bucket and is inserted into the edge of the recovery bucket, the clamping screw is screwed into the threaded hole and presses the edge of the recovery bucket in the clamping groove;

[0016] The end surface of the smoothing end is provided with a top threaded hole, and the length adjustment strip is provided with an oblong groove adapted to the top threaded hole. The positioning screw passes through the oblong groove and is threadedly engaged with the top threaded hole to press the length adjustment strip. One end of the elastic friction plate is provided with a bolt hole, and the fixing bolt passes through the bolt hole, the oblong groove and is fixed with a nut. The other end of the elastic friction plate extends vertically below the threaded segment of the fastener at the glue dripping station and contacts with each threaded segment passing through the glue dripping station.

[0017] Using this technical solution, dripping chemical glue is recovered through a recovery hopper and, after filtering out impurities, can be reused. The hopper serves as a retaining plate for the drip nozzle, allowing the brush to be removably inserted into the rim of the hopper, allowing for adjustment of the brush's position. The elastic friction plate is removably connected to the oblong groove via a fixing bolt. This allows the elastic friction plate to be fixed in a specific position, contacting the threaded section of a fastener passing through the glue dispensing station. The elastic friction plate evenly spreads the chemical glue on the threaded section. Furthermore, by adjusting the width of the elastic friction plate, the chemical glue can be directed to spread onto the thread threads at a specific width during contact, achieving precise glue application.

[0019] The horizontal adjustment mechanism includes a second screw rod, a second guide rod, a horizontal adjustment seat and a second hand wheel. The horizontal adjustment mechanism is horizontally arranged on the lifting seat, moves with the lifting seat, and is connected to the drip nozzle fixing seat to drive the drip nozzle fixing seat to move horizontally;

The position of the brush is specified according to the process requirements through the adjustable position structure of the brush, and the chemical glue is guided to be applied to the specified thread through the width of the elastic friction plate of the brush, so as to achieve precise gluing of the fastener.

[0029] To make the technical solution and its advantages of the present application clearer, the technical solution of the present application will be described in further detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only some embodiments of the present application and are only used to explain the present application, not to limit the present application. It should be noted that, for ease of description, only the parts related to the present application are shown in the accompanying drawings, and other related parts can refer to the general design. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other to obtain new embodiments.

[0030] The present invention is described in detail below with reference to the accompanying drawings. Figure 1-4 As shown,

[0031] A device for precisely applying glue to fasteners 5 includes a disc machine 1, a glue dispensing mechanism 2, a plurality of magnetic turntables 3, and a drive mechanism 4. The outer circumference of the disc of the disc machine 1 is provided with a plurality of rotating shafts equally spaced radially. The magnetic turntable 3 includes a connecting end 31 and a magnetic end 32. The connecting end 31 is axially fixed and axially rotatably engaged with the rotating shaft. The magnetic end 32 magnetically attracts the fasteners 5.

[0032] The disc machine 1 is provided with a glue dripping station. The disc machine 1 drives the magnetic turntable 3 to pass through the glue dripping station one by one. The driving mechanism 4 and the glue dripping mechanism 2 are arranged at the glue dripping station. The glue dripping mechanism 2 outputs liquid chemical glue to the threaded section 51 of the fastener 5 passing through the glue dripping station. The driving mechanism 4 contacts the magnetic turntable 3 passing through the glue dripping station, drives the magnetic turntable 3 to drive the fastener 5 to axially rotate at the glue dripping station.

[0033] A rotating shaft is set on the outer circumference of the disc of the disc machine 1, and then a magnetic turntable 3 is set on the outer circumference of the disc. The magnetic turntable 3 uses the connection between the connecting end 31 and the rotating shaft to realize axial positioning and axial rotation movement, and the magnetic end 32 can be provided with a magnet, or other existing technologies, so that the magnetic end 32 can magnetically absorb the fastener 5. When the fastener 5 is on the machine, it is coaxially arranged with the magnetic turntable 3, and is driven by the disc machine 1 to pass through the glue dripping station one by one.

[0034] At the glue dispensing station, the drive mechanism 4 contacts the magnetic turntable 3 passing through the station, causing it to rotate axially during contact. This configuration allows the chemical glue to be evenly applied to the threaded section 51 of the fastener 5 while the fastener 5 is in an axially rotating state. When the fastener 5, along with the disk, moves out of the glue dispensing station, the magnetic turntable 3 loses contact with the drive mechanism 4 and ceases axial rotation, facilitating subsequent drying and other processing steps.

[0035] The driving mechanism 4 includes a frame 41, a driving motor 42, a transmission belt 43, and a driving pulley 44, a tensioning pulley 45, and several driven pulleys 46 rotatably arranged on the frame 41. The several driven pulleys 46 are arranged in parallel and are located vertically above the magnetic turntable 3 passing through the glue dripping station. The transmission belt 43 is sleeved on the driving pulley 44, the tensioning pulley 45, and several driven pulleys 46, and is in friction contact with the outer peripheral surface of the magnetic turntable 3 passing through the glue dripping station. The driving motor 42 cooperates with the driving pulley 44 to drive the transmission belt 43 to rotate, and drives the glue dripping station magnetic turntable 3 with friction contact of the transmission belt 43 to rotate around the rotating axis.

[0036] By means of several driven pulleys 46 arranged in parallel, a contact area with a flat end is formed. The magnetic turntable 3 enters the glue-dropping station and contacts the transmission belt 43 on the outer periphery of the driven pulley 46. Due to the friction force of the contact, the turntable 3 forms an axial rotation along the rotation direction of the transmission belt 43.

[0037] The outer circumference of the magnetic turntable 3 is provided with a rolling pattern, and the magnetic end 32 of the magnetic turntable 3 is provided with a plug 321.

[0038] The provided plug post 321 is convenient for plugging into the fastener with a hole.

[0039] The glue-drip mechanism 2 includes a recovery bucket 21 and a brush member 22. The recovery bucket 21 is arranged vertically below the fastener 5 passing through the glue-drip station. The brush member 22 includes a clamping end, a smoothing end, a length adjustment strip 221, a positioning screw 222, an elastic friction plate 223 and a fixing bolt 224. The clamping end is provided with a clamping groove 225, a threaded hole passing through the clamping groove 225, and a clamping screw 226. The clamping groove 225 is adapted to the edge profile of the recovery bucket 21 and is inserted into the edge of the recovery bucket 21. The clamping screw 226 is screwed into the threaded hole and presses the edge of the recovery bucket 21 in the clamping groove 225.

[0040] The smoothing end face is provided with a top threaded hole, the length adjustment strip 221 is provided with an oblong groove adapted to the top threaded hole, the positioning screw 222 passes through the oblong groove and is threadedly engaged with the top threaded hole, and presses the length adjustment strip 221, one end of the elastic friction plate 223 is provided with a bolt hole, the fixing bolt 224 passes through the bolt hole, the oblong groove and is fixed with a nut, and the other end of the elastic friction plate 223 extends to vertically below the threaded segment 51 of the fastener 5 at the glue dripping station, and contacts with each threaded segment 51 passing through the glue dripping station.

[0041] The dripping chemical glue is recovered by the recovery hopper 21 and can be reused after filtering out impurities. The recovery hopper 21 serves as a drip nozzle holder, allowing the brush 22 to be removably inserted into the edge of the hopper 21. The position of the brush 22 itself can be adjusted, and the position of the elastic friction plate 223 can be adjusted by the removable connection between the fixing bolt 224 and the oblong groove. This allows the elastic friction plate 223 to be fixed in a designated position and contact the threaded section 51 of the fastener 5 passing through the glue dispensing station. The elastic friction plate 223 evenly spreads the chemical glue on the threaded section 51. Furthermore, by adjusting the width of the elastic friction plate 223, the chemical glue can be guided to spread onto the thread threads at a designated width during contact, achieving precise glue application.

[0042] The glue dripping mechanism 2 also includes a glue dripping nozzle 23, a dripping nozzle fixing seat 24, a base, a lifting adjustment mechanism 25, and a horizontal adjustment mechanism 26. The lifting adjustment mechanism includes a first screw rod, a first guide rod, a lifting seat and a first hand wheel. The lifting adjustment mechanism is vertically arranged on the base to drive the lifting seat to slide vertically.

[0043] The horizontal adjustment mechanism 26 includes a second screw rod, a second guide rod, a horizontal adjustment seat and a second hand wheel. The horizontal adjustment mechanism 26 is horizontally arranged on the lifting seat, moves with the lifting seat, and is connected to the drip nozzle fixing seat 24 to drive the drip nozzle fixing seat 24 to move horizontally.

[0044] The drip nozzle fixing base 24 is connected to the horizontal adjustment mechanism 26. The drip nozzle fixing base 24 is provided with a plurality of drip nozzle mounting holes. The glue drip nozzle 23 is fixed in the drip nozzle mounting hole and extends to the vertical upper side of the threaded section 51 of the fastener 5 passing through the glue dripping station.

[0045] The fixed position of the glue dripping nozzle 23 is controlled by the lifting adjustment mechanism 25 and the horizontal adjustment mechanism 26 so that the dripping chemical glue is at the specified position, and cooperates with other mechanisms to provide the accuracy of chemical glue coating.

[0046] Through the linkage cooperation of the disc machine 1, the magnetic turntable 3, and the driving mechanism 4, the fastener 5 is transferred to the glue dripping station and generates axial rotation, so that the chemical glue fully covers the outer peripheral surface of the threaded segment 51. The position of the brush 22 is specified according to the process requirements through the adjustable position structure of the brush 22, and the chemical glue is guided to be applied to the specified thread through the width of the elastic friction plate 223 of the brush 22, so as to achieve precise glue coating of the fastener 5.
