A guide rail of a series), a clip transfer platform vertically arranged at the exit end of the guide rail, which moves back and forth under the drive of the slide cylinder and the control of the photoelectric switch (the slide cylinder can drive the clip transfer platform to move back and forth, that is, to realize the cyclic switching between the picking station of the external supporting mechanical arm and the pushing station at the end of the guide rail; the photoelectric switch can timely transmit the signal of whether there is a clip for anchor in the sensing positioning slot to the electrical box of the material handling machine, providing a scientific basis for the next action instruction of the supporting mechanical arm and the slide cylinder); a positioning slot for the clip for the caliper anchor is provided on the clip transfer platform; the vibration plate assembly package The invention comprises a rotating disk which is driven by a vibrator to perform pulse vibration, a cylindrical shell which is buckled on the outer periphery of the rotating disk and extends upward, and a spiral ascending track which is arranged on the inner wall of the cylindrical shell in the shape of a winding mountain road. A notch is processed on the inner side of the end of the spiral ascending track. The narrowest width of the track corresponding to the notch section is equal to the diameter of the small end of the anchor clip, and the position of the notch is connected to an external high-pressure air blowing pipe (the pulse vibration of the rotating disk and the notch setting on the inner side of the end of the spiral ascending track are used to automatically select the anchor clip which can safely pass through the notch, that is, the anchor clip which meets the requirements of having the small end facing forward and the middle section facing downward to contact the spiral ascending track). The anchor clips that do not meet the screening conditions and are eliminated will directly fall from the gap to the rotating disk and be reshuffled - that is, the anchor clips with the large end facing forward or the conical surface facing downward in contact with the spiral ascending track will fall from the gap to the rotating disk one after another when passing through the gap because their center of gravity is in the gap area and with the assistance of the high-pressure wind blowing from the external high-pressure air pipe to the gap, and then be reshuffled into the queue for upward rotation, and the above operation will be repeated until they finally pass through the gap and slide into the guide rail in a state that meets the screening conditions.In this way, disorderly placed anchor clips can be neatly and orderly arranged in a directional manner, and accurately and automatically transported to the clip transfer platform; the remaining detection component includes a connecting plate, a proximity switch fixed to the top surface of the connecting plate, and a probe block hinged at the inner end of the connecting plate and whose top passes through the proximity switch sensing end during rotation (when an anchor clip passes by, it will collide with the probe block, and the probe block will rotate due to the collision, and the upper part of the probe block will approach the proximity switch during the rotation.

[0008] The guide rails described in the present invention include two identical outer guide rails and an inner guide rail arranged in parallel, the top surface of the outer guide rail is higher than the top surface of the inner guide rail (so that the top surfaces of the outer guide rail and the inner guide rail form a slope surface inclined inward, so that the anchor clip with the cone facing downward in contact with the spiral ascending track will overturn at this slope surface and fall onto the rotating disk and be reshuffled into the queue for upward rotation even if it passes through the gap by chance), and the outer edge spacing between the outer guide rail and the inner guide rail is smaller than the inner diameter of the anchor clip (to facilitate the sliding of the outer clamp of the anchor clip on the outer edge of the outer guide rail and the inner guide rail); V-shaped guardrail plates are arranged on both sides of the guide rails (to ensure the safe and normal sliding of the anchor clip).

[0009] In the present invention, an electrical box of the material handling machine is arranged in the cavity of the lower bracket (after receiving the induction signal, it sends control instructions to the corresponding electrical components), and the electrical box of the material handling machine is connected to the vibrator, proximity switch, photoelectric switch, slide cylinder, and circular cylinder in the cover opening cylinder through electrical signals.

[0010] The lifting conveyor described in the present invention includes a vibrating conveying hopper located at the low-end feed port (after the vibration of the vibrating conveying hopper, the anchor clip can be output to the conveying belt assembly relatively evenly), a conveying belt assembly with an elevator-like structure (which can lift and transport the anchor clip from the low end to the high end), and a guide plate located at the high end of the conveying belt assembly and facing the inlet of the fully automatic material sorting machine (which can smoothly guide the anchor clip into the inner cavity of the fully automatic material sorting machine).

[0011] The mechanical arm described in the present invention includes an arm base, two sets of clamping components that are rotatably mounted on the front end of the arm base and arranged at right angles and rotate in a linked manner (one set of clamping components is used to complete clamping during positioning sampling, automatic coding, and positioning layout, and the other set is used to complete clamping during positioning sampling); the clamping component is composed of a cylinder mounting plate, a clamping cylinder installed on the top surface of the front end of the cylinder mounting plate, and a pair of clamping claws installed at the front end of the clamping cylinder and capable of relative closure and expansion (the cylinder mounting plate is the mounting base of the clamping cylinder, and the pair of clamping claws are driven to relatively close and expand through the extension and contraction of the clamping cylinder, thereby completing the clamping or release of the anchor clip).

[0012] The nozzle of the inkjet printer described in the present invention is fixed on the front side of the working platform through a bracket and is close to the clip transfer platform of the full-automatic material sorting machine (to facilitate positioning and sampling and to enter the automatic inkjet link after running a short distance).

[0013] The working platform described in the present invention is a square box structure, and the center of the front end surface of the working platform is processed into an inwardly concave arc side surface (forming a groove and being located in the center area, which is convenient for arranging the robotic arm and arranging other equipment around the robotic arm, making the structural layout of the entire fully automatic detection system compact and reasonable), and a positioning and mounting hole for installing an automated hardness testing device is processed on the top surface of the working platform (to facilitate rapid positioning and installation of the automated hardness testing device).

[0014] The electrical box of the material sorting machine, the hardness tester electrical control system, the mechanical arm, the lifting conveyor and the inkjet printer in the fully automatic material sorting machine described in the present invention are all connected to the PLC control system in the form of electrical signals (the operation of each device in the present invention is coordinated and controlled by the PLC control system).

[0015] The design principle of the present invention is as follows:

[0016] The present invention includes a lifting conveyor, a fully automatic material handling machine, a mechanical arm, a printer, several automatic hardness testing devices, two recycling boxes and a PLC control system arranged in sequence according to the material flow direction, wherein all the automatic hardness testing devices are arranged on the front working platform in a semi-circular manner with the mechanical arm as the center, and the fully automatic material handling machine, the printer, and the recycling box are arranged behind the mechanical arm, and the material handling machine electrical box, the hardness meter electrical control system, the mechanical arm, the lifting conveyor, and the printer in the fully automatic material handling machine are connected to the PLC control system in the form of electrical signals. In this way, the present invention completes the Rockwell hardness detection and classification of the anchor clips through the coordinated control of the PLC control system on each device and the cooperation of the mechanical arm with each functional device. More specifically, the anchor clips that need to be tested for Rockwell hardness are lifted from the lower end to the higher end by the lifting conveyor, and fall into the fully automatic material sorting machine located directly below through the guide plate, completing the automatic feeding process; the rotating disk is driven by the vibrator to perform pulse vibration, and the anchor clips that fall on the rotating disk rotate together, and successively enter the spiral ascending track arranged in the shape of a winding mountain road on the inner wall of the cylindrical shell, and move up step by step along the spiral ascending track to the top end of the spiral ascending track, and pass through the inner gap at the end of the spiral ascending track. The screening of the opening allows only the anchor clips with the small end facing forward and the middle section facing downward to contact the spiral ascending track to safely pass through the gap, smoothly slide into the guide rail connected in a tangential manner for step-by-step sliding, and are accurately pushed into the positioning card slot in the clip transfer platform under the cooperation of the slide cylinder and the photoelectric switch. As for the anchor clips with the large end facing forward or the conical surface facing downward to contact the spiral ascending track, when passing through the gap, the center of gravity is in the gap area, and with the assistance of high-pressure air blowing from the external high-pressure air pipe to the gap, Under the action, they fall from the gap onto the rotating disk one after another, and are reshuffled into the queue for upward rotation in sequence, thus completing the automatic material sorting process; the robotic arm issues control instructions according to the PLC control system, first accurately clamps the anchor clip in the positioning slot, and then transfers it to the nozzle position facing the inkjet printer for inkjet printing, thus completing the positioning sampling and automatic inkjet printing process; then the robotic arm accurately places the anchor clip on the semicircular support table of the workpiece bracket in the automated hardness testing device, and the PLC controls the automated hardness testing device to select four points at the highest point of the arc surface of the anchor clip for Rockwell hardness testing. The PLC control system will compare the calculated Rockwell hardness value with the stored system reference value to determine whether the tested anchor clip is a qualified product, thus completing the positioning layout and positioning detection process; finally, the robotic arm grabs the tested anchor clip from the semicircular support table according to the control instructions of the PLC control system, rotates and shifts it, and places it in the recycling material box corresponding to the qualified or unqualified product at the rear, thus completing the positioning sampling process. Repeat the above operation to complete the Rockwell hardness measurement and classified recycling of the next and next batch of anchor clips.Therefore, the present invention can realize unmanned automated operation throughout the entire process from automatic feeding, automatic material sorting, positioned sampling, automatic coding, positioned layout, positioned detection to positioned sampling, and can accurately and efficiently perform unmanned batch testing of the Rockwell hardness value of anchor clips around the clock, and can feed back, summarize and analyze the measurement data to determine whether it is a qualified product and classify it for recycling, which has the advantages of high testing efficiency, accurate testing accuracy, high degree of automation and low testing cost.

[0017] In addition, when it is necessary to change the hardness test of anchor clips of different specifications, the present invention only needs to replace the semicircular support in the automated hardness testing device that matches the anchor clips of this specification. Therefore, the present invention also has the advantages of strong versatility and a wide range of applications.

[0018] The beneficial technical effects of the present invention are as follows:

[0019] The present invention can realize unmanned automated operation throughout the entire process from automatic feeding, automatic material sorting, positioned sampling, automatic coding, positioned layout, positioned detection to positioned sampling, and can accurately and efficiently perform unmanned batch testing of the Rockwell hardness values ​​of anchor clips around the clock, and can feed back, summarize and analyze the measurement data to determine whether they are qualified products and classify and recycle them, and can flexibly meet the hardness testing requirements of anchor clips of different specifications, and has the advantages of high testing efficiency, accurate testing accuracy, high degree of automation, strong versatility, wide range of applications and low testing cost.

[0043] The specific use of the present invention is as follows:

[0044] (i) Equipment layout: First, the various equipment in the present invention are arranged according to the description of the above-mentioned overall structural layout: that is, the lifting conveyor 1, the fully automatic material sorting machine 2, the robot arm 3, the inkjet printer 4, several automatic hardness testing devices 5, two recovery boxes 6 and the PLC control system are arranged in sequence according to the material flow direction, and the robot arm 3 is placed at the axial position of the arc side surface 7-1 of the front end face of the working platform 7, all the automatic hardness testing devices 5 are seated on the front working platform 7 in a semi-circular manner with the robot arm 3 as the center, and the fully automatic material sorting machine 2, the inkjet printer 4 and the recovery box 6 are all arranged behind the robot arm 3; then, according to the diameter specification of the anchor clip 2-12 to be tested, the corresponding matching semicircular support platform 5-3-1 is selected, and the semicircular support platform 5-3-1 is fixed on the sloped top surface of the inclined platform 5-3-2 by bolt connection.

[0045] (ii) Automatic feeding: Then, the anchor clip 2-12 that needs to be tested for Rockwell hardness is poured into the vibrating conveying hopper 1-1 located at the lower end of the lifting conveyor 1. The anchor clip 2-12 is relatively evenly output to the conveying belt assembly 1-2 with an elevator structure after being vibrated by the vibrating conveying hopper 1-1. The conveying belt assembly 1-2 then stably lifts and transmits it to the guide plate 1-3 located at the high end of the conveying belt assembly and facing the inlet of the fully automatic material sorting machine.

[0046] (III) Automatic material handling: At this time, the PLC control system sends a control command to the cover-opening cylinder 2-4 through the electrical box 2-2 of the material handling machine, and the cover-opening cylinder 2-4 extends, and the top cover of the upper box body 2-3 flips upward to open, and the anchor clip 2-12 on the guide plate 1-3 falls into the rotating disk 2-5-2 at the bottom of the inner cavity of the vibration disk assembly 2-5; after the material is received, the cover-opening cylinder 2-4 returns, and the top cover rotates and buckles on the top of the cylindrical shell 2-5-3 of the vibration disk assembly 2-5, and the electrical box 2-2 of the material handling machine controls the top cover of the vibration disk assembly 2-5. The vibrator 2-5-1 sends a control command, the vibrator 2-5-1 starts, and drives the rotating disk 2-5-2 to perform pulse vibration, so that the anchor clip 2-12 rotating with the rotating disk 2-5-2 successively enters the spiral ascending track 2-5-4 arranged like a winding mountain road on the inner wall of the cylindrical shell 2-5-3, and moves up step by step along the spiral ascending track 2-5-4; when the anchor clip 2-12 moves to the notch 2-5-4-1 on the inner side of the end of the spiral ascending track 2-5-4: only the small end faces forward The anchor clip 2-12 with the middle section facing downwards and contacting the spiral ascending track 2-5-4 can safely pass through the gap 2-5-4-1, smoothly slide into the guide rail 2-7 connected in a tangential manner for step-by-step sliding, and is accurately pushed into the positioning slot 2-8-1 in the clip transfer platform 2-8 under the cooperation of the slide cylinder 2-9 and the photoelectric switch 2-10, so that the external matching robot arm can accurately and quickly take samples from a fixed position; and for the large end facing forward or the conical surface facing downwards and contacting the spiral ascending track The anchor clips 2-12 of 2-5-4, when passing through the gap 2-5-4-1, fall from the gap to the rotating disk 2-5-2 one after another due to the center of gravity being in the gap area and with the assistance of the high-pressure wind blown from the external high-pressure air pipe to the gap 2-5-4-1, and are reshuffled into the queue for upward rotation in sequence, and the above operation is repeated until the small end is facing forward and the middle section is facing downward to contact the spiral ascending track 2-5-4, and successfully pass through the gap 2-5-4-1 and enter the guide rail 2-7. At the same time, in the present invention, the top surface of the outer guide rail 2-7-1 is higher than the top surface of the inner guide rail 2-7-2, so that the top surfaces of the outer guide rail 2-7-1 and the inner guide rail 2-7-2 form a slope surface inclined inward, so that the anchor clip 2-12 of the frustum contacting the spiral ascending track 2-5-4 with the cone face downward will overturn on this slope surface and fall onto the rotating disk 2-5-2 even if it happens to pass through the gap 2-5-4-1, and reshuffle into the team queuing up in sequence.

[0047] (IV) Positioning sampling: The PLC control system sends a control command to the robot arm 3. The robot arm 3 rotates to drive the clamping assembly 3-2 to move toward the clip transfer platform 2-8. When the clamping claws 3-2-3 are aligned with the anchor clip 2-12 in the positioning slot 2-8-1 in the clip transfer platform 2-8, the clamping cylinder 3-2-2 is actuated to drive the pair of clamping claws 3-2-3 to close and clamp the anchor clip 2-12.

[0048] (V) Automatic inkjet coding: The robot arm 3 drives the clamping claw hand 3-2-3 of the clamping anchor clip 2-12 to move to the position facing the nozzle 4-1 of the inkjet printer 4 to perform inkjet coding.

[0049] (VI) Positioning and positioning detection: After the coding operation, the anchor clip 2-12 moves to the workpiece bracket 5-3 in the automatic hardness testing device 5 with the rotation of the robot arm 3. After reaching the position, the clamping claw hand 3-2-3 presses down to clamp the anchor clip 2-12 to the semicircular support 5-3-1 of the workpiece bracket 5-3, so that the arc top surface of the semicircular support 5-3-1 is closely fitted with the inner cavity surface of the anchor clip 2-12; then, the PLC control system issues a horizontal movement control command through the horizontal moving platform electrical box 5-2-7 - that is, first By starting the X-axis driving device 5-2-1 to drive the X-axis moving platform 5-2-6 to move horizontally along the X-guide rail 5-2-9, the workpiece bracket 5-3 and the anchor clamp 2-12 can be adjusted to the center position in the X-axis horizontal direction, that is, the arc center axis of the anchor clamp 2-12 is coplanar with the measuring pressure head 5-1-3. Then, by starting the Y-axis driving device 5-2-5 to drive the Y-axis moving platform 5-2-4 to move horizontally along the Y-guide rail 5-2-8, the workpiece bracket 5-3 and the anchor clamp 2-12 can be adjusted to the desired position in the Y-axis horizontal direction. The required position, that is, the highest position of the curved surface of the anchor clip 2-12 is aligned with the center of the measuring pressure head 5-1-3; then, the PLC control system sends a rising test control command to the hardness tester electrical control system 5-1-5: that is, the lifting wheel 5-1-7 is controlled to rotate, driving the worm gear assembly 5-1-6 to rotate, and then adjusting the automatic lifting shaft 5-1-4 to rise, that is, adjusting the horizontal moving platform 5-2 and the anchor clip 2-12 to rise until the measuring pressure head 5-1-3 is pressed into the surface of the anchor clip 2-12, and maintaining the predetermined pressing time. Finally, the PLC control system issues a descending control command to the hardness tester electrical control system 5-1-5: that is, the lifting wheel 5-1-7 is controlled to rotate in the opposite direction, driving the worm gear assembly 5-1-6 to rotate, and then adjusting the automatic lifting shaft 5-1-4 to descend, the anchor clip 2-12 is disengaged from the measuring pressure head 5-1-3, and the Rockwell hardness value of the measured point is determined according to the indentation depth on the anchor clip 2-12. The Rockwell hardness value of the measured point will be displayed on the touch screen 5-1-1 in a timely manner through the hardness tester electrical control system 5-1-5. After the Rockwell hardness value test of the first measured point is completed, the anchor clip 2-12 is adjusted to move a certain distance in the X direction, that is, the second measured point is selected at the highest point of the curved surface of the anchor clip 2-12, and the above-mentioned ascending test control command is repeated to test the Rockwell hardness value of the second measured point. Select and test the Rockwell hardness value of the third point in turn, select and test the Rockwell hardness value of the fourth point; finally, the PLC control system will automatically calculate the average value of the Rockwell hardness values ​​of the four points based on the Rockwell hardness values ​​of the four points measured - that is, the Rockwell hardness value of the anchor clip 2-12; and the PLC control system will compare the calculated Rockwell hardness value with the stored system reference value to determine whether the tested anchor clip 2-12 is a qualified product.

[0050] (VII) Positioning and sampling: Then, the PLC control system sends a control command to the robot arm 3. The robot arm 3 starts another set of clamping components 3-2 and uses a corresponding pair of clamping claws 3-2-3 to grab the tested anchor clip 2-12 from the semicircular support 5-3-1 of the workpiece bracket 5-3 in the automated hardness testing device 5. The clamping claws 3-2-3 move up after grabbing the workpiece in place, and then rotate backward with the robot arm 3 to the recycling box 6 corresponding to the qualified products or unqualified products. One of the two recycling boxes 6 is used to hold qualified products and the other is used to hold unqualified products.

[0051] Repeat the above steps (iv), (v), (vi), and (vii), and the robot arm 3 repeats the above actions to perform positioning sampling, automatic coding, positioning layout, positioning detection, and positioning sampling on the next anchor clip 2-12, and accurately and efficiently complete the Rockwell hardness value test, and can judge whether it is a qualified product after feedback, summary and analysis of the measurement data and classify and recycle it. After a period of time, repeat steps (ii) and (iii) to automatically feed and sort the next batch of anchor clips 2-12. In this way, unmanned automated operation can be achieved from automatic feeding, automatic sorting, positioning sampling, automatic coding, positioning layout, positioning detection to positioning sampling, and the Rockwell hardness value of anchor clips can be accurately and efficiently tested in batches around the clock, and the measurement data can be fed back, summarized and analyzed to judge whether it is a qualified product and classify and recycle it. Therefore, the present invention has the advantages of high testing efficiency, accurate testing accuracy, high degree of automation, and low testing cost.

[0052] When it is necessary to change the hardness test of anchor clips of different specifications, the present invention only needs to replace the semicircular support 5-3-1 in the automated hardness testing device 5 that matches the anchor clips of this specification. Therefore, the present invention also has the advantages of strong versatility and wide application range.
