Description

Technical Field

[0001] The utility model belongs to the technical field of IPC classification B21J metal machining riveting auxiliary nail feeding equipment, and in particular relates to a structural improvement technology of a vibration plate automatic nail feeding machine equipment with improved queuing posture. Background Art

[0002] In stud welding, automatic nail feeding equipment is gradually being promoted.

[0003] However, in the past, nails were inserted manually. Although the efficiency of manual feeding is very low compared to that of automated equipment, in order to ensure piece-rate output and maximize their rights and interests, workers often insert studs into welding guns with high accuracy and direction. The auxiliary structure design of the vibration queuing in the vibration feeding of automatic nail feeding equipment is ingenious, but improvements to improve its accuracy are still in progress.

[0004] For example, patent application 201911172468.8 provides a control method for an automatic nail feeder to solve the problem of nail jamming, which relates to the technical field of automatic stud welding. The control method for an automatic nail feeder to solve the problem of nail jamming includes a PLC controller, a touch screen, a vibration plate and a solenoid valve, wherein the vibration plate is composed of a nail plate, a screw guide, a sensor and a push-pull cylinder.

[0005] Patent application 202311303751.6 relates to an automatic nail feeding mechanism of a riveting machine, comprising: a vibration plate, comprising a shell, a spring sheet, a vibration motor and a hopper, the spring sheet and the vibration motor are arranged in the shell, the hopper is arranged on the shell, the vibration motor is installed at the bottom of the hopper, the spring sheet is arranged at an angle, and the two ends are respectively connected to the hopper and the shell, and a spiral trough is arranged on the hopper; a conveying device, comprising a linear feeder and a feeding track installed on the linear feeder, and a feeding trough is provided on the feeding track; a discharging device, comprising a slide seat, a slider and a cylinder, a sliding hole is provided in the slide seat, the slider is arranged in the sliding hole, the cylinder is installed at one end of the slide seat, the piston rod of the cylinder is connected to the slider, a first groove is provided on the side of the slide seat, the first groove is connected to the sliding hole, a second groove is provided on the side of the slider, and a discharge hole is provided at the bottom of the slide seat.

[0006] Some automatic nail feeding equipment inevitably still has some studs that are eventually fed out in the wrong reverse posture, which leads to welding errors.

[0030] The utility model comprises: a detection sensor and a waste rejection actuator 10.

[0031] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0032] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.

[0033] The content of the present invention can be more easily understood by selecting the following preferred implementation methods and embodiments of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by ordinary technicians in the field to which the present invention belongs. When there is a conflict, the definition in this specification shall prevail.

[0034] Embodiment 1: As attached Figure 1 As shown, the hopper 1 is installed on the vibration plate 2, and the vibration plate 2 is installed with a vibration-damping fixed foot 3 at the bottom; a shell 4 is installed on the upper part of the hopper 1, and a top cone bin 5 is installed in the middle part of the shell 4. A spiral track 15 is installed in the top cone bin 5, and the bottom of the spiral track 15 is connected to the hopper 1. The upper end of the spiral track 15 spirals out of the top cone bin 5 and then connects to the front shifting track 8. The front shifting track 8 is located in the annular groove between the inner wall of the shell 4 and the outer wall of the top cone bin 5. Similarly, in the annular groove, the front shifting track 8 is further connected to the discharging track 6 through the discharge track 7, and the end of the discharging track 6 is led out of the outer wall of the shell 4; a detection sensor, a controller 9 and a waste rejection actuator 10 are installed on the upper side of the shell 4 next to the front shifting track 8.

[0035] In the foregoing, the sound and light alarm device 14 is installed on the upper side of the housing 4.

[0036] In the above, the second detection sensor 11 and the first detection sensor 13 are successively installed on the upper side of the housing 4 beside the front shifting track 8; further, the second detection sensor 11 and the first detection sensor 13 are connected to the identification device 12. Further, the identification device 12 is connected to the controller 9.

[0037] In the above, the front end of the detection sensor is located on the upper side of the center line on the front end and middle section of the front shift track 8, no more than three times the height of the outer diameter of the stud; correspondingly, the front end of the waste rejection actuator 10 is located on the upper side of the center line on the rear end of the front shift track 8, no more than three times the height of the outer diameter of the stud.

[0038] Preferably, the bottom surface of the annular groove between the inner wall of the shell 4 and the outer wall of the top cone bin 5 is conically inclined downward, and a slotted hole is partially opened on the outer wall of the top cone bin 5 at the bottom of the annular groove to connect the hopper 1 or the spiral track 15. It is convenient for the discarded studs to be re-vibrated and discharged.

[0039] Preferably, the sound and light alarm device 14 is installed beside the controller 9 or the identification device 12 .

[0040] Preferably, the waste rejection actuator 10 is a lever transmission mechanism. Alternatively, the waste rejection actuator 10 is an electromagnetic relay. The studs with abnormal posture in the online conveying direction on the vibration discharge track are rejected by instantaneous power on and off.

[0041] In the embodiment of the utility model, the vibration plate 2 generates vibrations through the motor and the vibrator, so that the studs in the hopper 1 are lined up in a certain posture in the spiral track 15 and transported in the direction of the track 8; in this stage, they pass through the first detection sensor 13 and the second detection sensor 11 in turn, and the detection signal is sent to the identification device 12. The identification device 12 determines whether the front end of the stud on the track is sharp or rough to determine whether the posture of the stud is in the correct direction. If an abnormality is found, the controller 9 drives the waste rejection actuator 10 to reject it. Furthermore, by adjusting the speed of the motor or the current of the vibrator, the vibration frequency of the vibration plate 2 can be accurately controlled by the device, thereby achieving efficient queuing and transportation of the studs. It should be noted that excessively high vibration frequencies may increase equipment wear, so it is necessary to find a balance between efficiency and equipment life.

[0042] In the embodiment of the utility model, the cone is identified by installing a second detection sensor 11 or a first detection sensor 13 for infrared detection to identify the roughness of the front end surface of the stud welding nail between the switching contact on the spiral track 15 and the front end of the front shift track 8. The identification device 12 uniformly identifies whether the conveying direction of the stud welding nails queued on the track is positive and negative. If an abnormality is found, the controller 9 starts to drive the waste rejection actuator 10 to accurately remove the stud welding nail with the abnormal reverse posture from the front shift track 8 into the hopper 1, and then enter the spiral track 15 again to ensure that the stud welding nails conveyed by the spiral track 15 to the discharge track 6 avoid the reverse abnormal situation, thereby achieving continuous and accurate nail supply.

[0043] In the embodiment of the utility model, further, after the second detection sensor 11 or the first detection sensor 13 detects and identifies an abnormal situation, the sound and light alarm device 14 is triggered to work and record it at the same time; after the controller 9 starts to drive the waste rejection actuator 10 and accurately removes the stud weld with the abnormal posture in the opposite direction, the sound and light alarm is released and the sound and light alarm device 14 returns to normal.

[0044] In the embodiment of the utility model, simple infrared online detection is combined with a dynamic servo waste rejection mechanism to realize timely elimination and correction of extremely rare reverse error posture studs that are about to be output at low cost.

[0045] In the present invention, in addition to infrared detection, the second detection sensor 11 and the first detection sensor 13 can also select a camera video detection device or a laser detection device.

[0046] Based on the above embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention, so as to avoid exhaustively listing all implementation methods that are unnecessary and impossible to list comprehensively.

[0047] The above are preferred embodiments of the present invention. It should be noted that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
