[0040] A cylindrical plug feeding device with a position correction function, comprising a feeding component 1, a support frame 2, a workpiece transfer component 4 and a workpiece position correction component 5;

[0041] The feeding component 1 includes a workpiece conveying channel 11, and a feeding groove 111 is provided on the top surface of the workpiece conveying channel 11; the workpiece transfer component 4 includes at least one workpiece gripper 44; the workpiece position correction component 5 includes a mounting frame 51, an imaging camera 52, a rotating motor 53, and a workpiece placement seat 54;

[0042] The feeding groove 111 extends in the front-rear direction; the output end of the feeding groove 111 is mounted on the top surface of the support frame 2; the workpiece gripper 44 is arranged near the output end of the feeding groove 111, and the workpiece gripper 44 can move back and forth; the imaging camera 52 is installed on the top of the mounting frame 51, and the imaging port of the imaging camera 52 faces downward; the rotating motor 53 is mounted on the bottom of the mounting frame 51, and the output end of the rotating motor 53 extends upward and is aligned with the imaging port of the imaging camera 52; the bottom surface of the workpiece placement seat 54 is connected to the output end of the rotating motor 53; the imaging camera 52 and the rotating motor 53 are respectively connected to the imaging recognition system in a signal manner.

[0043] Figure 1 It is a schematic structural diagram of an embodiment of a cylindrical plug feeding device with a position correction function according to the present invention, Figure 1 The connecting device 2 in is configured with two first straight pipe grippers 21 spaced apart front and back; Figure 2 It shows the installation structure of the mounting frame 2 and the feeding groove 111; Figure 3 It is a schematic structural diagram of the workpiece transfer component 4 of an embodiment of the present invention. In the figure, the workpiece transfer component 4 is an embodiment configured with two workpiece grippers 44; Figure 4 It is a schematic structural diagram of the workpiece position correction component 5 of an embodiment of the present invention; Figure 3 and Figure 4 The workpiece to be positioned 6 in is a cylindrical plug. The workpiece to be positioned 6 as a cylindrical plug is provided with a positioning groove 61 and an identification portion 62. The identification portion 62 is a part of a ring on the top of the workpiece to be positioned 6. The positioning groove 61 extends in the up-down direction and is vertically aligned with the identification portion 62. Therefore, by positioning the orientation of the identification portion 62, the orientation of the positioning groove 61 can be positioned.

[0044] Such as Figures 1-4As shown, during use, a workpiece gripper 44 picks up a workpiece 6 to be positioned from the output end of the feeding chute 111, then transfers and places the workpiece 6 to be positioned on the workpiece placement seat 54. The imaging camera 52 takes an image of the workpiece 6 to be positioned placed on the workpiece placement seat 54 and transmits the captured image to the imaging recognition system. The imaging recognition system compares and analyzes the received imaging image with a standard image and sends an electrical signal to the rotation motor 53 with the angle value required to rotate the workpiece 6 to be positioned. The rotation motor 53 rotates the corresponding angle value of the workpiece placement seat 54 according to the received electrical signal, so that the orientation of the recognition part 62 on the top surface of the corresponding workpiece 6 to be positioned is adjusted and corrected. Then, the workpiece gripper 44 picks up the workpiece 6 that has completed the orientation positioning from the workpiece placement seat 54 and transfers and places the workpiece 6 on the workpiece loading station of the assembly line.

[0045] Furthermore, it further includes a workpiece sorting component 3;

[0046] The workpiece sorting component 3 includes a sliding block 31, a guide rail 32, and a pushing cylinder 33;

[0047] The pushing cylinder 33 and the guide rail 32 are respectively installed on the top surface of the support frame 2; the guide rail 32 extends in the left-right direction and is close to the output end of the feeding chute 111; the sliding block 31 is mounted on the guide rail 32;

[0048] The sliding block 31 is provided with a workpiece receiving groove 311. The rear end surface of the sliding block 31 is in frictional contact with the front end surface of the workpiece conveying channel 11. The workpiece receiving groove 311 is recessed inward through the rear end surface of the sliding block 31. The workpiece receiving groove 311 is provided with an upper notch and a rear notch. The rear notch is used to align with the output end of the feeding chute 111 to input the workpiece 6 to be positioned, and the upper notch is used to expose the top of the workpiece 6 to be positioned to facilitate the workpiece gripper 44 to pick it up;

[0049] The output end of the pushing cylinder 33 is connected to the left end of the sliding block 31, and the pushing cylinder 33 pushes the sliding block 31 to move back and forth along the guide rail 32.

[0050] As Figure 2As shown in the figure, when the pushing cylinder 33 drives the sliding block 31 to move leftward to the leftmost position, the rear notch of the workpiece receiving groove 311 is aligned with the output end of the feeding groove 111, and a workpiece 6 to be positioned is input from the feeding groove 111 into the workpiece receiving groove 311; then the pushing cylinder 33 drives the sliding block 31 to move rightward, so that the workpiece receiving groove 311 is misaligned with the feeding groove 111, and the workpiece receiving groove 311 is located to the right of the feeding groove 111. At this time, the workpiece gripper 44 grabs the workpiece 6 to be positioned from the workpiece receiving groove 311, and transfers and places the workpiece 6 to be positioned on the workpiece placement seat 54. When the workpiece gripper 44 grabs the workpiece 6 to be positioned from the workpiece receiving groove 311, the pushing cylinder 33 drives the sliding block 31 to move leftward and reset.

[0051] Such a setting can prevent another workpiece 6 to be positioned at the forefront in the feeding groove 111 from hindering the workpiece gripper 44 from grabbing the workpiece 6 to be positioned in the workpiece receiving groove 311. In this way, the accuracy and perpendicularity of the workpiece 6 to be positioned grabbed by the workpiece gripper 44 can be improved, thereby improving the accuracy of the rotation angle value output by the imaging recognition system and the positioning accuracy of the output workpiece 6.

[0052] Furthermore, the workpiece feeding assembly 3 further includes a proximity switch 35;

[0053] The proximity switch 35 is mounted above the sliding block 31. The proximity switch 35 is located on the extension line of the central axis of the feeding groove 111, and the proximity switch 35 is signal-connected to the pushing cylinder 33.

[0054] As Figure 2 shown, when a workpiece 6 to be positioned is input into the workpiece receiving groove 311, the proximity switch 35 is triggered and sends a signal to the pushing cylinder 33, and the pushing cylinder 33 starts and drives the sliding block 31 to move rightward; through the induction of the proximity switch 35, it can be avoided that the pushing cylinder 33 is wrongly started when no workpiece 6 to be positioned is input into the workpiece receiving groove 311, thereby improving the operating effectiveness of the pushing cylinder 33.

[0055] Furthermore, the workpiece feeding assembly 3 further includes two first limiting rods 34;

[0056] The two first limiting rods 34 are respectively mounted on the top surface of the support frame 2 near the left and right ends of the guide rail 32; one ends of the two first limiting rods 34 are respectively used to abut against the left end face and the right end face of the sliding block 31.

[0057] As Figure 2 shown, the travel range of the sliding block 31 on the guide rail 32 can be limited by the two first limiting rods 34 to ensure that when the sliding block 31 reaches the end position of moving leftward, the workpiece receiving groove 311 is aligned with the output end of the feeding groove 111.

[0058] Specifically, the workpiece transfer assembly 4 includes a guide rail frame 41, a sliding drive cylinder 42, a sliding plate 45, two lifting cylinders 43, and two workpiece grippers 44;

[0059] The guide rail frame 41 is mounted between the support frame 2 and the mounting frame 51. A guide rail pair 411 extending in the front-rear direction is provided on the right end face of the guide rail frame 41;

[0060] The sliding plate 45 is slidably mounted on the guide rail pair 411. The two lifting cylinders 43 are mounted on the right plate surface of the sliding plate 45 at intervals in the front-rear direction. The output ends of the two lifting cylinders 43 are arranged downward. The rear ends of the two workpiece grippers 44 are respectively connected to the output ends of the two lifting cylinders 43, and the claw grippers of the workpiece grippers 44 are arranged forward;

[0061] The sliding drive cylinder 42 is mounted at the rear end of the guide rail frame 41; the output end of the sliding drive cylinder 42 extends forward and is connected to the rear plate surface of the sliding plate 45. The sliding drive cylinder 42 pushes the sliding plate 45 to move back and forth along the guide rail pair 411.

[0062] As Figure 1 and Figure 3 shown, through the cooperation of the sliding drive cylinder 42, the sliding plate 45, the two lifting cylinders 43, and the two workpiece grippers 44, the two workpiece grippers 44 can move up and down synchronously while moving back and forth synchronously, so as to improve the operation convenience and stability of the two workpiece grippers 44 for gripping and placing the workpiece 6 to be positioned and the workpiece 6 that has completed positioning.

[0063] Specifically, the workpiece gripper 44 located at the rear can pick up a workpiece 6 to be positioned from the workpiece receiving groove 311, transfer and place this workpiece 6 to be positioned on the workpiece placement seat 54, and synchronously pick up the workpiece 6 that has completed positioning from the workpiece placement seat 54 through the workpiece gripper 44 located at the front, and transfer and place this workpiece 6 on the workpiece loading station of the assembly line, thereby improving the loading work efficiency of the cylindrical plug feeding device with a position correction function.

[0064] Furthermore, the workpiece transfer assembly 4 further includes two second limiting rods 46;

[0065] The two second limiting rods 46 are respectively mounted at the front and rear ends of the guide rail pair 411, and one ends of the two second limiting rods 46 are respectively used to abut against the front end face and the rear end face of the sliding plate 45.

[0066] As Figure 1 and Figure 3As shown in the figure, the travel range of the sliding plate 45 on the guide rail pair 411 can be limited by two second limit rods 46, so that when the sliding plate 45 is closest to the rear end of the guide rail pair 411, the two workpiece grippers 44 are respectively aligned vertically with the workpiece receiving groove 311 and the workpiece placement seat 54, and when the sliding plate 45 is closest to the front end of the guide rail pair 411, the two workpiece grippers 44 are respectively aligned vertically with the workpiece placement seat 54 and the workpiece loading station of the assembly line.

[0067] Furthermore, the feeding assembly 1 further includes a vibrating bowl 13;

[0068] The vibrating bowl 13 is installed near the rear of the workpiece conveying channel 11, and the workpiece output port of the vibrating bowl 13 is communicated with the input end of the feeding groove 111.

[0069] As Figure 1 shown, the vibrating bowl 13 can continuously and orderly output the workpieces 6 with the rings facing upward to the workpiece conveying channel 11, which can save the operation of manually placing the workpieces 6 with the rings facing upward in the workpiece conveying channel 11 and reduce the labor cost.

[0070] Furthermore, the feeding assembly 1 further includes a linear vibrator 12;

[0071] The linear vibrator 12 is installed below the workpiece conveying channel 11, and the top surface of the linear vibrator 12 abuts against the bottom surface of the workpiece conveying channel 11;

[0072] The feeding groove 111 is arranged with the front end lower than the rear end.

[0073] As Figure 1 shown, by arranging the feeding groove 111 with the front end lower than the rear end and vibrating the workpiece conveying channel 11 by the linear vibrator 11, the workpieces 6 can be conveyed to the workpiece receiving groove 311 one by one in contact with each other along the feeding groove 111, which can improve the production efficiency of the cylindrical plug feeding device with a position correction function.

[0074] In summary, as Figures 1-4 shown in the embodiment of the present invention, for the cylindrical plug feeding device with a position correction function, the workpiece gripper 44 is used to complete the transfer of the workpiece 6 between the feeding groove 111, the workpiece placement seat 54 and the workpiece loading station, and the imaging camera 52 and the rotating motor 53 are used in cooperation to rotate the workpiece 6 to correct the orientation of the positioning groove 61 of the corresponding workpiece 6. Not only does it eliminate the need for manual discharging of the workpiece 6, but also the orientation of the positioning groove of each workpiece 6 of the cylindrical plug can be controlled, thereby improving the working efficiency of the drainage chassis assembly line.
