Description

[Technical field]

[0001] The invention belongs to the field of chain saw processing equipment, and in particular relates to a chain saw guide plate suspension chain line type spraying line. [Background technology]

[0002] Plastic spraying is a surface treatment method that sprays plastic powder on parts. Its working principle is to charge the plastic powder through high-voltage electrostatic equipment, and spray the paint on the surface of the workpiece under the action of the electric field. The powder will be evenly adsorbed on the surface of the workpiece to form a powder coating; and the powder coating will be leveled and solidified after high-temperature baking, and the plastic particles will melt into a dense final protective coating with different effects; firmly attached to the surface of the workpiece. Plastic spraying is a very important process in the production of chain saw guides. It not only plays a decorative role, but also plays a very effective protective role for the chain saw guides, which can prevent the chain saw guides from being eroded by light, rain, dew, water and various media.

[0003] The Chinese utility model patent with reference announcement number CN 206763246 U discloses an automatic coating production line for chain saw guide plates, including a spray booth for powder coating the chain saw guide plates and a suspension conveyor chain for conveying the chain saw guide plates through the spray booth, wherein the spray booth is provided with an atomizer, a high-voltage electrostatic generator and a spray gun. The applicant currently uses this chain saw guide plate suspension chain line spraying line, in which the guide plate needs to be hung on the hook of the suspension conveyor chain before entering the spray booth, and after the spraying is completed (including subsequent drying), the guide plate needs to be removed from the hook, which is currently basically done manually, with high labor intensity and affecting the overall efficiency of the spraying line.

[0004] Although robot technology is relatively mature, there are still some technical difficulties in realizing the robot to hang the guide plate on the spray hook and remove the guide plate from the spray hook. The main technical difficulties are: because the hook running on the suspension chain line shakes during operation, the hook must be in a stable and uniform running state during automatic loading and unloading, otherwise it is difficult for the robot to align; in addition, because the hook shakes during operation, it is difficult to ensure that the protruding part of the hook is facing the direction of the robot, resulting in the robot being unable to hang up and down accurately. [Summary of the invention]

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a chain saw guide bar hanging chain line spray line, so that the hook is in a set direction when in the loading and unloading station, and at the same time solves the problem that the hook cannot keep stable when the robot automatically loads and unloads, thereby ensuring that the robot can be accurately hung up and down.

[0011] A magnetic synchronous conveying component is arranged downstream of the spray hook orienting mechanism and upstream of the upper hanging station and the lower hanging station. The magnetic synchronous conveying component includes a conveying member running along a circular path and a magnetic member arranged on the conveying member. The conveying member keeps synchronization with the running speed of the suspension chain line.

[0012] Preferably, the first directional channel and the second directional channel include channel side plates arranged on opposite sides, and upstream ends of the first directional channel and the second directional channel are both provided with guide inlets.

[0017] Preferably, the spray hook is provided with a magnetic positioning block cooperating with the magnetic member, and the magnetic positioning block is provided with a magnetic surface facing the conveying member.

[0018] Preferably, a limiting member is provided on the opposite side of the magnetic synchronous conveying component, and the limiting member cooperates with the magnetic positioning block to form a limiting conveying channel for the spray hook to pass through between the limiting member and the conveying member.

[0020] Preferably, a limiting side plate is provided below the conveying member and on one side of the guide plate.

[0021] The present invention adopts the above technical solution and has the following beneficial effects:

[0022] The loading robot corresponds to the upper hanging station setting, and is used to hang the guide plate on the spray hook. The unloading robot corresponds to the lower hanging station setting, and is used to remove the guide plate from the spray hook. The robot and motion control system simulate and replace the manual loading and unloading actions, which can reduce labor intensity, save labor costs, and significantly improve spraying efficiency.

[0023] Combined with the structure of the current hook assembly, the hook assembly includes a chain plate hook and a spray hook, the chain plate hook includes a chain plate, a hanging ring arranged at the lower side of the chain plate, a central column arranged at the upper side of the chain plate and a pin arranged at the outer side of the central column, the upper end of the spray hook is provided with an upper hanging hook suspended from the hanging ring, and the lower end is provided with a lower hanging hook for hanging the guide plate. Whether in the upper hanging station or the lower hanging station, it is necessary to ensure that the lower hanging hook protrudes to one side of the upper feeding robot and the unloading robot, so that the feeding robot can accurately put the groove on the grasped guide plate into the hook, or the unloading robot can separate the groove on the grasped guide plate from the hook. Since the chain plate hook can be rotated horizontally, the relative angle of the chain plate hook in the horizontal direction basically determines the protruding direction of the lower hanging hook, because the upper hanging hook is suspended from the hanging ring, in the natural state, the protruding direction of the upper hanging hook is basically perpendicular to the vertical plane where the hanging ring is located, and the protruding directions of the upper hanging hook and the lower hanging hook are the same, that is, the protruding direction of the lower hanging hook is basically perpendicular to the vertical plane where the hanging ring is located. Based on the above analysis, in order to ensure that the lower hanging hook protrudes to one side of the upper feeding robot and the unloading robot, on the one hand, the chain plate hook is designed accordingly, and at the same time, a spray hook orientation mechanism is designed. When the hook assembly passes through the spray hook orientation mechanism, the spray hook orientation mechanism acts on the chain plate hook to change the relative angle of the chain plate hook, so that the lower hanging hook protrudes to one side of the upper feeding robot and the unloading robot. Among them, the spray hook orientation mechanism includes a first orientation component and a second orientation component, the first orientation component is provided with a first orientation channel, the first orientation channel cooperates with the lifting ring to locate the relative angle of the chain plate hook and make the lower hanging hook face the set direction, and the second orientation component is provided with a second orientation channel, the second orientation channel cooperates with the center column and the pin to locate the relative angle of the chain plate hook and make the lower hanging hook face the set direction. After passing through the first orientation component and the second orientation component, finally, the lower hanging hook faces one side of the feeding robot and the unloading robot, that is, the oriented direction, thereby completing the orientation process.

[0024] The working principle of the magnetic synchronous conveying component is: according to the linear speed feedback from the suspension chain line, a synchronous conveyor belt embedded with magnetic materials is precisely and synchronously controlled by the servo system. After the spray hook runs to the corresponding position of the magnetic synchronous conveying component, the mutual attraction between the magnetic positioning block and the synchronous conveyor belt is used to keep the spray hook relatively stable during operation. The speed of the suspension chain line is consistent with the speed of the synchronous conveyor belt, and they run synchronously within a certain range, so that the spray hook will not shake or rotate. In relatively stable operation, after the camera recognizes and calculates the position and speed of the spray hook, the robot can accurately place the upper groove of the grasped guide plate on the hook, or remove the guide plate from the hook, so as to realize the automatic upper and lower guide plate action. The robot and motion control system can simulate and replace the manual loading and unloading actions, which can reduce labor intensity, save labor costs, and significantly improve spraying efficiency.

[0025] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0045] Reference Figures 1 to 12 As shown, the embodiment of the present invention provides a chain saw guide plate hanging chain line type spraying line, including a hanging chain line 1, a spray room 4, a loading robot 6 and a unloading robot 7. The hanging chain line 1 is provided with a hook assembly 100 for hanging a guide plate 13. The overall structure of the guide plate before spraying has been formed, and a groove 131 is provided on it. Among them, the hook assembly includes a chain plate hook 11 and a spraying hook 12. The chain plate hook 11 includes a chain plate 111 and a hanging ring 114 arranged on the lower side of the chain plate. The hanging ring is approximately a semicircular ring, which extends vertically downward as a whole and is perpendicular to the chain plate 111. The upper end of the spraying hook 12 is provided with an upper hanging hook 121 suspended from the hanging ring, and the lower end is provided with a lower hanging hook 122 for hanging the guide plate. The upper hanging hook 121 and the lower hanging hook 122 are both hook-shaped structures protruding to one side, and the upper hanging hook opens downward, and the lower hanging hook opens upward. In addition, the upper hanging hook and the lower hanging hook have the same protruding direction. The above is the conventional structure of the current hook assembly.

[0046] In order to enable the robot to hang the guide plate on the spray hook and remove the guide plate from the spray hook during the operation of the suspension chain line 1, the suspension chain line 1 is provided with an upper hanging station, a spraying station and a lower hanging station along its operation path. The loading machine 6 is arranged corresponding to the upper hanging station, used to hang the guide plate on the spray hook, and the unloading robot 7 is arranged corresponding to the lower hanging station, used to remove the guide plate from the spray hook. Both the loading robot and the unloading robot can adopt mature robot technology, because the upper hanging action and the lower hanging action themselves are not complicated. Of course, it also needs to cooperate with the visual system. At the upper hanging station and the lower hanging station, the camera 8 of the visual system collects the image of the hook hanging guide plate to provide information support for the robot action.

[0047] Combined with the structure of the current hook assembly, the problems existing in the upper and lower hanging of the robot are explained. Whether in the upper hanging station or the lower hanging station, it is necessary to ensure that the lower hanging hook 122 protrudes to one side of the upper feeding robot and the lower feeding robot, so that the upper feeding robot can accurately put the groove 131 on the grasped guide plate into the hook, or the lower feeding robot can separate the groove 131 on the grasped guide plate from the hook. Since the chain plate hook 11 can rotate horizontally, the relative angle of the chain plate hook 11 in the horizontal direction basically determines the protruding direction of the lower hanging hook 122. Because the upper hanging hook 121 is suspended from the ring 114, in the natural state, the protruding direction of the upper hanging hook 121 is basically perpendicular to the vertical plane where the ring is located, and the protruding directions of the upper hanging hook and the lower hanging hook are the same, that is, the protruding direction of the lower hanging hook 122 is basically perpendicular to the vertical plane where the ring is located. Before hanging on the guide plate, the relative angle of the chain plate hook 11 is disordered. In addition, when the hook assembly 100 hangs the guide plate through the spray room 4 for spraying, the chain plate hook 11 needs to be rotated. After the spraying is completed, it is also in a disordered state after leaving the spray room. For disordered hooks, the robot cannot accurately hang and lower the guide plate.

[0048] Based on the above analysis, in order to ensure that the lower hanging hook 122 protrudes to the side where the upper feeding robot 6 and the unloading robot 7 are located, on the one hand, the chain plate hook 11 is designed accordingly, and the spray hook orientation mechanism 3 is also designed. When the hook assembly passes through the spray hook orientation mechanism 3, the spray hook orientation mechanism 3 acts on the chain plate hook 11 to change the relative angle of the chain plate hook 11, so that the lower hanging hook 122 protrudes to the side of the upper feeding robot and the unloading robot. Among them, the chain plate hook 11 includes a central column 112 arranged on the upper side of the chain plate and a pin 113 arranged on the outer side of the central 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. The first orientation channel 311 cooperates with the lifting ring 114 to locate the relative angle of the chain plate hook and make the lower hanging hook face the set direction. The second orientation component 32 is provided with a second orientation channel 321. The second orientation channel 321 cooperates with the central column 112 and the pin 113 to locate the relative angle of the chain plate hook and make the lower hanging hook face the set direction.

[0049] like Figure 6 As shown, the projection of the pin and the center column and the ring on the horizontal plane has a 90-degree angle, which is only an approximate angle and a certain angle deviation can be allowed, such as an angle between 80 and 90 degrees. Even after orientation, the lower hanging hook 122 can protrude to one side of the upper feeding robot and the lower feeding robot without affecting the upper and lower hanging of the robot, and does not have to be in a very precise position.

[0050] like Figures 7 to 9As shown, the first directional channel 311 and the second directional channel 321 include channel side plates arranged on opposite sides, and the upstream ends of the first directional channel 311 and the second directional channel 321 are both provided with guide inlets. The opposite sides of the guide inlets are provided with arc-shaped guide parts, and the arc-shaped guide parts on both sides cooperate to form a bell-mouth structure. The channel side plates are slat-shaped structures, and the guide inlet parts are bent outward in an arc shape to form an arc-shaped guide part, and the chain plate hook is guided into the directional channel through the guide inlet.

[0051] It is understandable that the first directional channel 311 and the second directional channel 321 are connected, and a spacing space is provided at the connecting portion. Here, the connection is not directly connected, but the spacing space is reserved, which is to provide a turning space for the positioning chain plate hook to rotate a certain angle.

[0052] Since the hook assembly can only rotate in one direction each time it passes through the first orientation component 31 and the second orientation component 32, multiple turns are required to complete the final orientation. Figure 4 As shown, in some embodiments, along the running direction of the suspension chain line, a first orienting component 31, a second orienting component 32, and a first orienting component 31 are sequentially provided from upstream to downstream. This is because before passing through the spray hook orienting mechanism 3, in a natural state, the lifting ring in the chain disk hook 11 has a certain angle with the running direction of the suspension chain line spray line, and the center column 112 is closer to the front relative to the pin 113. However, after being oriented by the spray hook orienting mechanism 3, the lifting ring in the chain disk hook 11 is roughly the same as the running direction of the suspension chain line spray line, and the lower hanging hook 122 protrudes to one side of the upper feeding robot and the unloading robot. Figure 7 As shown, after passing through the upstream first orientation component, the upper hanging hook 121 and the lower hanging hook 122 are oriented toward a first direction, which is opposite to the direction after orientation. Figure 8 As shown, after the second orientation component, the upper hanging hook 121 and the lower hanging hook 122 are oriented toward the second direction, and at this time, an angle is formed with the oriented direction. Fig. 9 As shown, after the downstream first orientation component, the upper hanging hook 121 and the lower hanging hook 122 are directed to the third direction, that is, the orientation direction, thereby completing the orientation process.

[0053] Furthermore, along the running direction of the suspension chain line, a directional limiting component 33 is also provided downstream of the first directional component 31, and the directional limiting component 33 is connected to the magnetic attraction synchronous conveying component 2, and is used to keep the spray hook 12 in a directional state after orientation and convey it downstream to the magnetic attraction synchronous conveying component 2. Specifically, the directional limiting component 33 includes a first directional limiting strip 331 provided on one side of the hanging ring and a second directional limiting strip 332 provided on one side of the center column. The first directional limiting strip 331 and the second directional limiting strip 332 are both slat-like structures, and are both located on the same side, that is, the side of the protruding direction of the upper hanging hook 121 and the lower hanging hook 122 after the spray hook 12 is oriented. Due to the different heights of the hanging ring and the center column, the first directional limiting strip 331 and the second directional limiting strip 332 are different in height. In addition, the first directional limit strip 331 and the second directional limit strip 332 are staggered along the running direction of the suspension chain line, that is, the first directional limit strip 331, the second directional limit strip 332, the first directional limit strip 331, the second directional limit strip 332, etc. are arranged in sequence. Of course, the opposite ends of the first directional limit strip 331 and the second directional limit strip 332 have staggered parts in the front-to-back direction in horizontal projection (the left-to-right direction is still staggered) to form a continuous directional limit. The upstream ends of the first directional limit strip 331 and the second directional limit strip 332 are both provided with an arc-shaped guide section bent toward the protruding direction of the upper suspension hook and the lower suspension hook.

[0054] Since the hook running on the suspension chain line shakes during operation, the hook must be in a stable and uniform speed operation state when automatically loading and unloading. Therefore, a magnetic attraction synchronous conveying component 2 is provided, and the magnetic attraction synchronous conveying component 2 includes a conveying member running along a circular path and a magnetic member provided on the conveying member. The conveying member keeps synchronization with the running speed of the suspension chain line. The magnetic attraction synchronous conveying component is provided corresponding to the upper hanging station and the lower hanging station, and the magnetic member generates suction on the spray hook to keep the spray hook stable during operation.

[0055] In this embodiment, the magnetic synchronous conveying component 2 includes a synchronous belt assembly 22, which includes a synchronous conveyor belt 221 and a synchronous pulley matched with the synchronous conveyor belt, that is, the conveying member is a synchronous conveyor belt, and the synchronous conveyor belt is driven by a servo motor 222. The magnetic member can be embedded in the synchronous conveyor belt 221, or can be bonded to the surface of the synchronous conveyor belt 221.

[0056] In order to ensure that the magnetic part produces a stable suction force on the spray hook so that the spray hook remains stable during operation. The spray hook 12 is provided with a magnetic positioning block 123 that cooperates with the magnetic part, 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 conveyor 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 large magnetic attraction force, such as magnetic steel, and the magnetic positioning block 123 is fixed to the vertical rod part of the spray hook body by a locking screw.

[0057] Furthermore, the magnetic synchronous conveying component 2 includes a synchronous conveying bracket 21, and the servo motor 222 is vertically installed on the top of the synchronous conveying bracket and is connected to a reducer, and the output shaft of the reducer is connected to the synchronous pulley.

[0058] It is understandable that the synchronous conveying bracket 21 can also be provided with a support column with adjustable height. The specific height adjustment structure refers to the prior art, such as a telescopic tube structure, so as to adjust the height of the synchronous conveying belt 221 to ensure that the synchronous conveying belt 221 corresponds to the height of the magnetic positioning block of the spray hook.

[0059] Furthermore, a limit member 23 is provided relative to the magnetic synchronous conveying component 2, and the limit member 23 cooperates with the magnetic positioning block 123 to form a limit conveying channel for the spray hook to pass through between the limit member and the conveying member. Specifically, the limit member 23 is a long strip structure, and a guide section 231 is provided at the inlet end of the limit member, and the guide section can be bent outward in an arc shape. It can be understood that for the rectangular body structure of the magnetic positioning block 123, the width of the limit conveying channel allows the magnetic positioning block 123 to pass through the gap, but it cannot rotate horizontally.

[0060] Furthermore, a guide member 24 is provided upstream of the position-limiting conveying channel, and the guide member 24 is used to guide the spray hook into the position-limiting conveying channel. Specifically, the guide member is a plate-like structure, and is located below the position-limiting conveying channel, and cooperates with the part below the magnetic positioning block 123 of the spray hook 12. It includes an oblique section 241 away from one end of the position-limiting conveying channel, a transverse section 243 close to one end of the position-limiting conveying channel, and an arc transition section 242 connecting the oblique section 241 and the transverse section 243.

[0061] In addition, a limiting side plate 25 can be provided below the conveyor, at a height corresponding to the guide plate 13, on one side of the guide plate 13, so as to prevent the guide plate from shaking significantly and affecting the robot's hanging up and hanging down of the guide plate. In addition, a guide side plate 26 is connected to the upper part of the limiting side plate 25 at its upstream, and the guide side plate 26 has a similar structure to the guide member 24.

[0062] The working principle of the magnetic synchronous conveying component is: according to the linear speed feedback from the suspension chain line, a synchronous conveyor belt embedded with magnetic materials is precisely and synchronously controlled by the servo system. After the spray hook runs to the corresponding position of the magnetic synchronous conveying component, the mutual attraction between the magnetic positioning block and the synchronous conveyor belt is used to keep the spray hook relatively stable during operation. The speed of the suspension chain line is consistent with the speed of the synchronous conveyor belt, and they run synchronously within a certain range, so that the spray hook will not shake or rotate. In relatively stable operation, after the camera recognizes and calculates the position and speed of the spray hook, the robot can accurately place the upper groove of the grasped guide plate on the hook, or remove the guide plate from the hook, so as to realize the automatic upper and lower guide plate action. The robot and motion control system can simulate and replace the manual loading and unloading actions, which can reduce labor intensity, save labor costs, and significantly improve spraying efficiency.

[0063] In addition, referring to the prior art, the guide plate needs to be cleaned before spraying, so the chain saw guide plate hanging chain line spraying line also includes a cleaning device 5, which is independently set from the hanging chain line 1. The cleaning device 5 includes an automatic feeding mechanism 51, an A-side cleaning machine 52, a B-side cleaning machine 54, a guide plate automatic turning 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 them in the A-side cleaning machine 52 for polishing and cleaning of the A-side. After the guide plate is polished and cleaned on the A-side, the guide plate automatic turning mechanism 53 realizes automatic turning, and then sends it to the B-side cleaning machine 53 for polishing and cleaning of the B-side, and then sends it to the high-pressure cleaning machine 55 for high-pressure water spray cleaning.

[0064] The above is only a specific embodiment of the invention, but the protection scope of the invention is not limited thereto. Those skilled in the art should understand that the invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the invention will be included in the scope of the claims.
