[0002] Spark plugs are important components of gasoline engine ignition systems, and are mainly composed of wire nuts, insulators, wire screws, center electrodes, side electrodes, and shells.

Preferably, the number of tooling seats 3 can be several, and the several tooling seats 3 are evenly distributed in a ring array. The tooling seat 3 is penetrated by a slot 301, and the inner wall of the slot 301 is coaxially provided with a support ring 302. The inner wall of the support ring 302 cooperates with the inner wall of the slot 301 to form a support cavity for the spark plug body 1 to be plugged in. The support cavity is used to support the spark plug body 1 so as to position the spark plug body 1 in the slot 301. The material transport rotation drive device is composed of a cam divider and a motor. The cam divider is driven by a motor to work. It is a prior art and will not be described in detail here. The correction frame 4 is arranged at intervals with the feeding tray 21, and the material transport rotary drive device drives the feeding tray 21 to rotate until the tooling seat 3 with the spark plug body 1 is placed moves to a position corresponding to the correction frame 4, and then the material transport rotary drive device stops the feeding tray 21, so that the tooling seat 3 with the spark plug body 1 is placed stops at the inspection position.

Preferably, the hollow rotating platform 61 or the correction frame 4 is provided with an angle sensor for measuring the rotation angle of the correction frame 4, which is used to sense the rotation angle of the correction frame 4. The outer wall of the hollow rotating platform 61 is provided with a sensing member 17, and the driving motor 62 is provided with a sensing device 18 at a position close to the hollow rotating platform 61. The sensing end of the sensing device 18 is inductively matched with the sensing member 17, and the sensing end of the sensing device 18 has an active space for the sensing member 17 to pass through. The sensing device 18 can be a metal sensor, and the sensing member 17 can be an inductive metal. When the sensing member 17 enters the active space of the sensing end, the sensing device 18 triggers the origin signal, controls the material transport rotation drive device to stop at the initial position, and completes the reset of the correction frame 4.

[0028] The correction frame 4 is fixedly connected with a visual inspection device 5 at a position relative to the tooling seat 3. Preferably, the visual inspection device 5 is a CCD camera. A connecting frame 10 is also provided on the correction frame 4. A fill light device 11 is provided at the end of the connecting frame 10 away from the correction frame 4. The lighting end of the fill light device 11 corresponds to the detection end of the visual inspection device 5, and the space between the fill light device 11 and the visual inspection device 5 is for the tooling seat 3 loaded with the spark plug body 1 to pass through. The fill light device 11 is an illumination lamp, which fills light for the visual inspection device 5 so that the visual inspection device 5 can collect a good quality image.

[0029] The correction assembly includes a correction head 7 located above the workbench 3, a second rotary drive device 8 for driving the correction head 7 to rotate, and a lifting drive device 9 for driving the second rotary drive device 8 to rise and fall relative to the correction frame 4.

[0030] refer to Figure 1 , Figure 2 , Figure 6 , Figure 7When the material transport device 2 moves the tooling seat 3 on which the spark plug body 1 is placed to a position corresponding to the correction frame 4, the central axis of the spark plug body 1 is coaxially arranged with the hollow rotating platform 61, and the drive motor 62 is used to drive the hollow rotating platform 61 to rotate so that the correction frame 4 rotates around the central axis of the spark plug body 1. The central axis of the spark plug body 1 is L1. The visual inspection device 5 moves with the correction frame 4, and the detection end of the visual inspection device 5 corresponds to the spark plug body 1 on the tooling seat 3, so as to collect image information of the spark plug body 1 on the tooling seat 3, and the image information includes information of the side electrode 101 and the center electrode 102 at the top of the spark plug body 1. When the visual inspection device 5 detects that the bent end 103 of the side electrode 101 is aligned with the top end of the center electrode 102, the welding position of the side electrode 101 is correct, and the spark plug body 1 is qualified. The material transport device 2 sends the qualified spark plug body 1 to the next workstation and sends the next spark plug body 1 to be inspected to the inspection position; when the visual inspection device 5 detects that the bent end 103 of the side electrode 101 is deviated from the top end of the center electrode 102, the welding position of the side electrode 101 is deviated, and the spark plug body 1 is unqualified. The first rotary drive device 6 drives the visual inspection device 5 to move circumferentially around the axis L1 to adjust the angular position of the inspection end of the visual inspection device 5, so that the inspection end of the visual inspection device 5 collects the image of the end face of the bent end 103 of the side electrode 101 on the spark plug body 1, thereby finding the welding center of the side electrode 101, so that the correction device can subsequently perform a correction operation on the deviated side electrode 101.

When the correction device corrects the deviation of the spark plug body 1, the mounting frame 13 is driven to descend along the length direction of the linear slide rail 12 by the lifting drive device 9, and the mounting frame 13 drives the second rotary drive device 8 and the deviation correction head 7 to move to the top of the spark plug body 1. At this time, the top of the spark plug body 1 passes through the limit ring 16, and the limit ring 16 is used to limit the top of the spark plug body 1 to ensure that the position of the spark plug body 1 is stable during the deviation correction operation. According to the deviation of the side electrode 101, the second rotation drive device 8 drives the correcting head 7 to rotate. Preferably, the rotation axis of the correcting head 7 is L2, and the axis L2 is coaxially arranged with the welding center of the electrode. The rotating correcting head 7 drives the eccentrically arranged pressure-applying part 701 to make a circumferential movement around the welding center of the side electrode 101, so that the pressure-applying part 701 applies pressure to the bent end 103 of the side electrode 101 to deform it, thereby realizing the position correction of the bent end 103 of the side electrode 101. After the position of the bent end 103 of the side electrode 101 is corrected, the lifting drive device 9 drives the mounting frame 13 to rise along the linear slide rail 12, so that the limit ring 16 and the correcting head 7 are separated from the top of the spark plug body 1, and the correction assembly is reset.

[0032] The correction device replaces manual inspection and manual correction by using a visual inspection device 5 and a correction component, thereby reducing labor costs, making the inspection and correction of the spark plug body 1 more accurate, improving production efficiency, and ensuring the production quality of the spark plug body 1.

[0033] Preferably, the correction frame 4 is provided with a buffer assembly, the buffer assembly includes two buffer members 14 arranged opposite to each other, the mounting frame 13 is provided with an abutment portion 1301, the abutment portion 1301 is located between the two buffer members 14, preferably, the buffer member 14 is an elastic buffer, which is a prior art and will not be described in detail here.
