[0004] Although the robot technology is relatively mature, there are still some technical problems in realizing the hanging and taking off of the guide plate by the robot. The main technical difficulties are as follows: since the hooks running on the suspension chain line are shaking during running, the hooks must be in a stable and uniform running state during automatic feeding and discharging, otherwise the robot is difficult to align.

Therefore, the features limited by "first" and "second" can explicitly or implicitly include at least one of the features.

[0043] Referring to Figures 1 to 12 The utility model discloses a chain saw guide plate hangs chain line formula spraying line, including hanging chain line 1, spray house 4, feeding robot 6 and discharging robot 7, the hanging chain line 1 is equipped with hook assembly 100 for hanging guide plate 13, and the whole structure of guide plate has been formed before spraying, and has groove 131 on it. Among them, the hook assembly includes chain disc hook 11 and spraying hook 12, the chain disc hook 11 includes chain disc 111 and the lifting ring 114 arranged on the lower side of the chain disc, and the lifting ring is approximately semicircular ring, and the whole extends vertically downward, and is perpendicular to the chain disc 111. The upper end of the spraying hook 12 is provided with the upper suspension hook 121 suspended in the lifting ring, and the lower end is provided with the lower suspension hook 122 for suspending the guide plate, the upper suspension hook 121 and the lower suspension hook 122 are all hook-shaped structures formed to one side, and the opening of the upper suspension hook is downward, and the opening of the lower suspension hook is upward, and in addition, the protruding direction of the upper suspension hook and the lower suspension hook is same, and the above is the conventional structure of the hook assembly.

[0044] In order to realize the robot to hang the guide plate on the spraying hanger and take the guide plate off the spraying hanger during the robot running on the hanging chain line 1, the hanging chain line 1 is provided with an upper hanging station, a spraying station and a lower hanging station along its running path, the feeding robot 6 is arranged corresponding to the upper hanging station for hanging the guide plate on the spraying hanger, and the discharging robot 7 is arranged corresponding to the lower hanging station for taking the guide plate off the spraying hanger. Either the feeding robot or the discharging robot can adopt mature robot technology, because the upper hanging action and the lower hanging action are not complex themselves, and of course, a vision system is also needed to cooperate, at the upper hanging station and the lower hanging station, a camera 8 of the vision system collects the image of the hanger hanging the guide plate to provide information support for the robot action.

[0045] In combination with the structure of the current hanger assembly, the problems existing in the robot upper hanging and lower hanging are described. It is necessary to ensure that the lower hanging hanger 122 protrudes to the side of the feeding robot and the discharging robot, so as to facilitate the feeding robot to accurately put the slot 131 on the grabbed guide plate into the hanger, or the discharging robot to separate the slot 131 on the grabbed guide plate from the hanger. Since the chain disc hanger 11 can rotate horizontally, the relative angle of the chain disc hanger 11 in the horizontal direction basically determines the protruding direction of the lower hanging hanger 122, because the upper hanging hanger 121 is hung on the lifting ring 114, and in the natural state, the protruding direction of the upper hanging hanger 121 is basically perpendicular to the vertical plane where the lifting ring is located, and the protruding directions of the upper hanging hanger and the lower hanging hanger are the same, that is, the protruding direction of the lower hanging hanger 122 is basically perpendicular to the vertical plane where the lifting ring is located. Before the guide plate is hung, the relative angle of the chain disc hanger 11 is disordered, in addition, when the hanger assembly 100 hangs the guide plate to pass through the spraying room 4 for spraying, the chain disc hanger 11 needs to rotate, and after the spraying is completed, it is also in a disordered state. For the disordered hanger, the robot cannot accurately realize the guide plate hanging and discharging.

[0046] Based on the above analysis, in order to ensure that the lower suspension hook 122 protrudes to the side where the up feeder robot 6 and the down feeder robot 7 are located, on the one hand, the chain disc hook 11 is designed accordingly, and at the same time, the spray hook orientation mechanism 3 is also designed. During the process of the hook assembly passing through the spray hook orientation mechanism 3, the spray hook orientation mechanism 3 acts on the chain disc hook 11 to change the relative angle of the chain disc hook 11, so that the lower suspension hook 122 protrudes to the side of the up feeder robot and the down feeder robot. Among them, the chain disc hook 11 includes a center column 112 arranged on the upper side of the chain disc and a pin 113 arranged on the outer side of the center column. The spray hook orientation mechanism 3 includes a first orientation component 31 and a second orientation component 32. The first orientation component 31 is provided with a first orientation channel 311, which cooperates with the lifting ring 114 to position the relative angle of the chain disc hook and make the lower suspension hook face the set direction. The second orientation component 32 is provided with a second orientation channel 321, which cooperates with the center column 112 and the pin 113 to position the relative angle of the chain disc hook and make the lower suspension hook face the set direction.

[0047] As shown in Figure 6 , the angle between the line connecting the pin and the center column and the projection of the lifting ring on the horizontal plane is 90 degrees. Here, it is only an approximate angle, and a certain angle deviation can be allowed, for example, an angle between 80 and 90 degrees. Even after orientation, as long as the lower suspension hook 122 protrudes to the side of the up feeder robot and the down feeder robot, it does not affect the hanging of the robot, and it is not necessary to be very accurate in position.

[0048] As shown in Figures 7 to 9 , the first orientation channel 311 and the second orientation channel 321 include channel side plates arranged on opposite sides. The upstream ends of the first orientation channel 311 and the second orientation channel 321 are each provided with a guide inlet. The opposite sides of the guide inlet are provided with arc-shaped guide portions, and the arc-shaped guide portions on both sides cooperate to form a horn structure. The channel side plates are in the form of a strip, and the guide inlet portion is outwardly arc-shaped and bent to form an arc-shaped guide portion, guiding the chain disc hook into the orientation channel through the guide inlet.

[0049] It can be understood that the first orientation channel 311 and the second orientation channel 321 are connected, and a spacing is provided at the connection position. Here, the connection is not direct connection, but a spacing is left to provide a turning space for positioning the chain disc hook to turn a certain angle.

[0050] Since the hook assembly can only turn in one direction each time it passes through the first orientation component 31 and the second orientation component 32, in order to complete the final orientation, it needs to be turned multiple times. As shown in Figure 4As shown, in some embodiments, the first orientation component 31, the second orientation component 32, and the first orientation component 31 are sequentially arranged along the running direction of the hanging chain line from upstream to downstream. This is because, before passing through the spray hook orientation mechanism 3, the hanger ring in the chain disc hook 11 has a certain angle with the running direction of the hanging chain line spray line in the natural state, and the center column 112 is more forward relative to the pin 113. But after orientation through the spray hook orientation mechanism 3, the hanger ring in the chain disc hook 11 is roughly parallel to the running direction of the hanging chain line spray line, and the lower hanging hook 122 protrudes to the side of the feeding robot and the discharging robot. As shown in Figure 7 As shown, the upper hanging hook 121 and the lower hanging hook 122 are made to face the first direction through the upstream first orientation component, which is opposite to the direction after orientation. Figure 8 As shown, the upper hanging hook 121 and the lower hanging hook 122 are made to face the second direction through the second orientation component, which has an angle with the direction after orientation. Figure 9 As shown, the upper hanging hook 121 and the lower hanging hook 122 are made to face the third direction, i.e. the direction after orientation, through the downstream first orientation component, thereby completing the orientation process.

[0051] Further, along the running direction of the hanging chain line, the orientation limiting component 33 is arranged downstream of the first orientation component 31, which is connected with the magnetic attraction synchronous conveying component 2 and used to convey the oriented spray hook 12 downstream to the magnetic attraction synchronous conveying component 2 in the oriented state. Specifically, the orientation limiting component 33 includes the first orientation limiting strip 331 arranged on one side of the hanger ring and the second orientation limiting strip 332 arranged on one side of the center column. Both the first orientation limiting strip 331 and the second orientation limiting strip 332 are in the form of a plate strip and located on the same side, i.e. the side of the protruding direction of the upper hanging hook 121 and the lower hanging hook 122 after orientation of the spray hook 12. Because the hanger ring and the center column have different heights, the first orientation limiting strip 331 and the second orientation limiting strip 332 also have different heights. In addition, the first orientation limiting strip 331 and the second orientation limiting strip 332 are staggered along the running direction of the hanging chain line, i.e. the first orientation limiting strip 331, the second orientation limiting strip 332, the first orientation limiting strip 331, the second orientation limiting strip 332, and so on are sequentially arranged. Of course, the opposite ends of the first orientation limiting strip 331 and the second orientation limiting strip 332 have staggered parts in the front-back direction in the horizontal projection (the left-right direction is still staggered), so as to form continuous orientation limiting. The upstream ends of the first orientation limiting strip 331 and the second orientation limiting strip 332 are both provided with arc-shaped guide sections bent towards the side of the protruding direction of the upper hanging hook and the lower hanging hook.

[0052] Since the hooks running on the hanging chain line are swinging in operation, the hooks must be in a stable and uniform running state during automatic feeding and discharging. Therefore, a magnetic synchronous conveying component 2 is arranged, which comprises a conveying member running along an annular path and a magnetic member arranged on the conveying member, the conveying member is kept synchronous with the running speed of the hanging chain line, and the magnetic synchronous conveying component is arranged corresponding to the upper hook station and the lower hook station, and the magnetic member generates an attractive force on the spraying hook to keep the spraying hook stable during operation.

[0053] In the embodiment, the magnetic synchronous conveying component 2 comprises a synchronous belt assembly 22, which comprises a synchronous conveying belt 221 and a synchronous pulley matched with the synchronous conveying belt, that is, the conveying member is a synchronous conveying belt, and the synchronous conveying belt is driven by a servo motor 222. The magnetic member can be embedded in the synchronous conveying belt 221 or adhered to the surface of the synchronous conveying belt 221.

[0054] In order to ensure that the magnetic member generates a stable attractive force on the spraying hook to keep the spraying hook stable during operation, the spraying hook 12 is provided with a magnetic positioning block 123 matched with the magnetic member, and the magnetic positioning block 123 is provided with a magnetic surface facing the conveying member. Specifically, the magnetic positioning block 123 is a rectangular body, so that a larger magnetic surface facing the synchronous conveying belt 221 is formed on one side of the magnetic positioning block 123. The magnetic positioning block 123 is made of a material with a larger magnetic force, such as a magnetic steel, and is fixed with a vertical rod part in the spraying hook body by a locking screw.

[0055] Further, the magnetic synchronous conveying component 2 comprises a synchronous conveying bracket 21, the servo motor 222 is vertically installed on the top of the synchronous conveying bracket, and is connected with a speed reducer, and the output shaft of the speed reducer is connected with the synchronous pulley.

[0056] It can be understood that the synchronous conveying bracket 21 can also be provided with an adjustable height support column. The specific height adjusting structure can refer to the prior art, such as a telescopic pipe structure, so as to adjust the height of the synchronous conveying belt 221, and ensure that the height of the synchronous conveying belt 221 corresponds to the magnetic positioning block of the spraying hook.

[0057] Further, a limiting piece 23 is arranged opposite to the magnetic synchronous conveying component 2, the limiting piece 23 is limitedly matched with the magnetic positioning block 123, and a limiting conveying channel for the spraying hook to pass through is formed between the limiting piece and the conveying member. Specifically, the limiting piece 23 is in a long strip structure, and the inlet end of the limiting piece is provided with a guide section 231, which can be curved outward in a circular arc shape. It can be understood that for the rectangular body structure of the magnetic positioning block 123, the width of the limiting conveying channel allows the magnetic positioning block 123 to pass through with a gap, but cannot be horizontally rotated.

[0058] Further, a guide piece 24 is arranged upstream of the limiting conveying passage, and the guide piece 24 is used to guide the spraying hanger into the limiting conveying passage. Specifically, the guide piece is a plate-shaped structure, and is arranged below the limiting conveying passage and cooperates with the lower part of the magnetic attraction positioning block 123 of the spraying hanger 12. The guide piece comprises a slanting section 241 at one end away from the limiting conveying passage, a transverse section 243 at one end close to the limiting conveying passage, and a circular arc transition section 242 connecting the slanting section 241 and the transverse section 243.

[0059] In addition, a limiting side plate 25 can be arranged below the conveying piece and at the height of the guide plate 13, and the limiting side plate 25 is arranged at one side of the guide plate 13, so as to prevent the guide plate from shaking greatly and affecting the robot to hang and unhang the guide plate. In addition, the upper part of the limiting side plate 25 is connected with a guide side plate 26 at the upstream thereof, and the guide side plate 26 is similar to the guide piece 24.

[0060] The working principle of the magnetic attraction synchronous conveying component is that: according to the line speed of the hanging chain line, a synchronous conveying belt embedded with magnetic material is accurately and synchronously controlled by a servo system, after the spraying hanger runs to the corresponding position of the magnetic attraction synchronous conveying component, the mutual attraction between the magnetic attraction positioning block and the synchronous conveying belt is used to keep the spraying hanger relatively stable during the running. The speed of the hanging chain line is consistent with the speed of the synchronous conveying belt, and the spraying hanger is synchronously run within a certain range, so that the spraying hanger will not shake and rotate. In the relatively stable running, the position and speed of the spraying hanger are identified and calculated by the camera, and the guide plate is accurately placed on the hanger or taken off from the hanger by the robot, so as to realize the automatic hanging and un-hanging of the guide plate. The robot and the motion control system are used to simulate and replace the manual hanging and un-hanging action, so as to reduce the labor intensity, save the labor cost, and significantly improve the spraying efficiency.

[0061] In addition, according to the prior art, the guide plate needs to be cleaned before being sprayed, and therefore the chain saw guide plate hanging chain line type spraying line further comprises a cleaning device 5 which is arranged independently from the hanging chain line 1. The cleaning device 5 comprises an automatic feeding mechanism 51, an A-face cleaning machine 52, a B-face cleaning machine 54, a guide plate automatic turnover mechanism 53, and a high-pressure cleaning machine 55. The robot of the automatic feeding mechanism 51 automatically grabs multiple guide plates from the stacking table and places the guide plates on the A-face cleaning machine 52 to perform A-face polishing and cleaning. After the guide plates are polished and cleaned on the A face, the guide plate automatic turnover mechanism 53 is used to automatically turn over the guide plates, and then the guide plates are sent to the B-face cleaning machine 53 to perform B-face polishing and cleaning, and then the guide plates are sent to the high-pressure cleaning machine 55 to perform high-pressure water cleaning.

[0062] The above descriptions are only specific embodiments of the utility model, and the protection scope of the utility model is not limited to this, and the skilled in the art should understand that the utility model includes but is not limited to the content described in the drawings and the above specific embodiments.Any modification not deviating from the function and structural principle of the utility model will be included in the scope of claims.
