[0040] Wherein, the laser cleaning device includes two first trusses 5 arranged in parallel, and the two first trusses 5 are respectively installed on the columns of the workshop equipment support frame 1 by bolts, and two second trusses 6 arranged perpendicular to the two are arranged between the two first trusses 5 by bolts, and two second trusses 6 are arranged, and a linear slide rail A 7 parallel to the second truss 6 is arranged on one second truss 6, and a first rodless cylinder 8 and a linear slide rail B 9 are arranged on the other second truss 6. Specifically, a tripod 10 is installed on the side of the second truss 6, and the linear slide rail B 9 is installed on the tripod 10.

A laser support frame 14 is connected to the piston of the second rodless cylinder 12 by bolts, and the laser support frame 14 is slidably connected to the linear slide rail C 13 at the same time, and a laser head 15 installed by bolts is arranged on the laser support frame 14;

[0041] The laser cleaning device also includes a laser generator 16, and the laser head 15 is connected to the laser generator 16 via an optical fiber, thereby forming a laser generating system;

[0042] In this embodiment, the laser support frame 14 includes a first steel plate 141, a bending plate 142, a bracket plate 143, a second steel plate 144, and a third steel plate 145; wherein the first steel plate 141 is horizontally arranged, and a first long hole 146 penetrating the first steel plate 141 is provided on its upper surface, a bolt which simultaneously penetrates the bending plate 142 is provided in the first long hole 146, a nut is provided at the bottom end of the bolt, and the connection between the first steel plate 141 and the bending plate is completed by the cooperation between the bolt and the nut, similarly, a second long hole 147 is provided on the side of the bending plate 142, and the bracket plate 143 is connected to the bending plate 142 by the bolt and nut at the second long hole 147; the second steel plate 144 is vertically arranged on the lower surface of the first steel plate 141, and the third steel plate 145 is horizontally arranged on the lower surface of the second steel plate 144, wherein the bracket plate 143 is connected to the aforementioned laser head 15 by bolts, and the third steel plate 145 is connected to the second rodless cylinder 12 by bolts;

[0043] Since there may be installation errors during installation and the laser head 15 has high requirements on the working distance precision, the laser support frame 14 is an adjustable mechanism: during adjustment, the bending plate 142 can be adjusted forward and backward through the first long hole 146, and the bracket plate 143 can be adjusted up and down through the second long hole 147 to adjust its relative position with the bending plate 142.

[0044] An air collecting hood 17 connected by bolts is also provided on the support plate 11 for collecting smoke generated during the laser cleaning process, and the air collecting hood 17 is connected to the vacuum cleaner 3 through the air duct 3-1; further, the present invention also includes a workshop top steel frame 18, and a hanger 19 is provided on the workshop top steel frame 18, and the air duct 3-1 of the vacuum cleaner 3 is hung on the hanger 19.

[0045] The return track 2 is horizontally installed on the horizontal column of the workshop equipment support frame 1, and the return track 2 is parallel to the second truss 6. The swing arm group runs along the return track 2 under the drive of the motor in the swing arm system, wherein the swing arm group includes a front swing arm 20 and a rear swing arm 21, and the front swing arm 20 and the rear swing arm 21 are both provided with copper contacts;

[0046] A drag chain 22 is installed on the support plate 11 by bolts to protect the cables of various components;

[0047] Two connecting frames 23 are connected between the two second trusses 6, and the two connecting frames 23 are respectively located at the two ends of the second trusses 6, and the support plate 11 is located between the two connecting frames 23. A guide groove 24 parallel to the return track 2 is installed between the two connecting frames 23. In this embodiment, the guide groove 24 includes a low flat section 241, an uphill section 242 and a high flat section 243 arranged in sequence along the direction away from the laser head 15;

[0048] Specifically, both ends of the guide groove 24 are provided with adjustment components connected to the connecting frame 23, and the adjustment components are used to adjust the height of the guide groove 24;

[0049] Specifically, the adjustment assembly includes a vertically arranged long screw 25, on which an adjustment nut 26 is threadedly connected, an adjustment block 27 fixedly connected to the guide groove 24 is arranged on the top surface of the adjustment nut 26, a fastening nut 28 threadedly connected to the long screw 25 is arranged on the upper surface of the adjustment block 27, and a locking nut 29 threadedly connected to the long screw 25 is threadedly connected above the fastening nut 28;

[0050] A guide rod 30 is installed in the guide groove 24, and the guide rod 30 can roll along the guide groove 24, wherein the guide rod 30 includes an optical axis 301, and connecting shafts 302 are respectively arranged on both sides of one end of the optical axis 301, and cone wheels 303 connected by rolling bearings are arranged on the two connecting shafts 302, and the guide rod 30 is rollingly connected to the guide groove 24 through the cone wheels 303, and the arrangement of the two cone wheels 303 has the functions of centering and preventing falling off;

[0051] Furthermore, a first limiting cylinder 304 is provided between the cone wheel 303 and the rolling bearing, and the first limiting cylinder 304 is used for inward limiting. Specifically, the first limiting cylinder 304 is sleeved on the connecting shaft 302 and clamped between the cone wheel 303 and the optical axis 301. When the cone wheel 303 and the rolling bearing have a tendency to move toward the direction of the optical axis 301, the first limiting cylinder 304 clamps the cone wheel 303 and the rolling bearing, so that the two cannot move toward the direction of the optical axis 301; the ends of the two connecting shafts 302 that are away from each other are both provided with retaining springs 305 to prevent the cone wheel 303 and the rolling bearing from falling off;

[0052] An inverted concave wheel frame 306 is installed by bolts at the other end of the optical axis 301. Specifically, two parallel vertical clamping plates are arranged on the top of the concave wheel frame 306, and a clamped plate inserted into the gap between the two vertical clamping plates is installed at the bottom end of the optical axis. The bolts are threaded through the vertical clamping plate-clamped plate-vertical clamping plate respectively to complete the detachable installation of the concave wheel frame 306. In case of a failure, the concave wheel frame 306 can be quickly dismantled to avoid affecting the production of the entire line.

[0053] The inner walls on both sides of the wheel frame are rotatably connected with a push wheel 307 through a rotating shaft and a rolling bearing. Furthermore, second limiting cylinders 308 for limiting the push wheel 307 are respectively arranged on both sides of the push wheel 307, and the two second limiting cylinders 308 are sleeved on the rotating shaft and are in contact with the inner wall of the wheel frame. The second limiting cylinders 308 are arranged to prevent the push wheel 307 from sliding along the rotating shaft.

[0054] In the present invention, the cone wheel 303 runs in the guide groove 24. The conical design of the cone wheel can ensure the centering of the operation and prevent the wheel from falling off in the guide groove. The push wheel 307 of the guide rod 30 is in contact with the rocker group and is made into a wheel to prevent hard friction with the rocker group.

[0055] Furthermore, a rib plate 31 is connected to the side of the support plate 11 facing away from the laser head 15, and the other end of the rib plate 31 is connected to a vertically arranged sleeve 32, and a sliding bearing 33 is arranged in the sleeve 32. The aforementioned guide rod 30 can cooperate with the sliding bearing 33 to slide up and down along the sleeve 32, and the sliding bearing 33 and the sleeve 32 are interference fit.

[0056] A first detection switch 34 is installed on the return track 2, and the first detection switch 34 is located on one side of the return track 2 close to the low flat section 241 of the guide groove 24, and the first detection switch 34 is used to detect the arrival of the front swing bar 20 and the rear swing bar 21;

[0057] A second detection switch 35 is installed on the workshop equipment support frame 1. The second detection switch 35 is used to distinguish whether the device arriving is the front swing bar 20 or the rear swing bar 21. Specifically, the front swing bar 20 is provided with a numbering rod 201. The second detection switch 35 distinguishes whether the device arriving is the front swing bar 20 or the rear swing bar 21 by detecting the position of the numbering rod 201.

[0058] A third detection switch 36 is also installed on the return track 2, and the third detection switch 36 is located directly below the high flat section 243 of the guide groove 24. The third detection switch 36 is used to detect whether the front swing arm 20 and the rear swing arm 21 have passed through the device;

[0059] A trigger switch 37 is installed at the highest point of the upslope section 242 of the guide groove 24 .

[0060] Furthermore, a photoelectric switch 38 is installed on one first truss 5, and a reflector 39 corresponding to the photoelectric switch 38 is provided on the other first truss 5. Under normal circumstances, the reflector 39 transmits light to the light source photoelectric switch 38. If someone blocks it, the photoelectric switch 38 cannot receive the light source. At this time, the control system is informed that someone has mistakenly entered.

[0061] It is worth mentioning that the present invention is also provided with a control system, which is coupled with each electrical component, can receive signals from each electrical component, and control the opening and closing of each electrical component.

[0062] The working principle and beneficial effects of the present invention are:

[0063] First, it should be noted that the present invention only cleans the rear swing bar 21 and does not clean the front swing bar 20;

[0064] When the device is in operation, the swing arm system (the swing arm system is a prior art and will not be described in detail here) drives the swing arm to run along the return track 2, passing through the low flat section 241, the uphill section 242 and the high flat section 243 of the guide groove 24 in sequence;

[0065] During this process, the swing rod first moves to the laser cleaning device, and first hits the guide rod 30. The swing rod pushes the guide rod 30 to move along the guide groove 24. During this process, the first rodless cylinder 8 is in a follow-up state, and both ends are not ventilated. Therefore, the support plate 11 connected to the guide rod 30 through the rib plate 31 and the sleeve 32 will move with the guide rod 30. When the first detection switch 34 detects that the swing rod has arrived, and the second detection switch 35 is not triggered, it means that the swing rod is the rear swing rod 21. At this time, the laser generating system works, and the laser head 15 on the support plate 11 that runs together with the rear swing rod 21 strips the paint accumulated on the contact of the rear swing rod 21.

[0066] When the guide rod 30 moves to the uphill section 242 of the guide groove 24, the guide rod 30 gradually rises along the slope of the guide groove 24 and slides upward along the sliding bearing 33 in the sleeve 32. As the guide rod 30 gradually rises, the guide rod 30 and the rear swing rod 21 are about to be gradually separated. When the separation is about to be completed, the guide rod 30 hits the trigger switch 37 installed on the guide groove 24. The trigger switch 37 senses that the guide rod 30 is in place and sends a signal to the control system. When the guide rod 30 triggers the trigger switch 37, the control system controls the laser generating system to stop. At the same time, the control system controls the solenoid valve in the first rodless cylinder 8 to be energized, and the first rodless cylinder 8 starts to ventilate, so that the piston of the first rodless cylinder 8 continues to run toward the high flat section 243 of the guide groove 24, so that the guide rod 30 connected thereto through the support plate 11, the rib plate 31 and the sleeve 32 runs to the high flat section 243, so that the guide rod 30 waits in the high flat section 243 for the rear swing rod 21 to pass through, and at this time, the rear swing rod 21 is completely separated from the guide rod 30, and the rear swing rod 21 continues to move forward under the drive of the swing rod system;

[0067] Until the second detection switch 35 detects that the front swing arm 20 has arrived and the third detection switch 36 detects that the front swing arm 20 has passed, the piston of the first rodless cylinder 8 starts to run in reverse to the initial state under the control of the control system. When the cleaning of one side of all the swing arm groups is completed, the piston of the second rodless cylinder 12 drives the support plate 11 to move left and right, thereby driving the laser head 1 to move to the contact on the other side of the swing arm to start the next working cycle. During this working process, the laser head 1 cleans the other contact of the swing arm that has not been cleaned, and so on and so forth to achieve follow-up cleaning of the two contacts of the rear swing arm 21. The present invention adopts a purely mechanical structure for follow-up, which can reduce the failure rate. In the event of a failure, the structure of the guide groove 24 and the guide rod 30 will not cause obstruction to the operation of the swing arm group and will not affect the production of the entire line.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
