Description

TECHNICAL FIELD

[0001] The application relates to the technical field of plastic recycling processing, in particular to a plastic part processing device for automobile interior decoration. BACKGROUND

[0002] Plastic recycling is of great significance in the manufacturing of automobile plastic parts and is a core measure to promote the sustainable development of the industry. A large amount of waste plastics is generated from the scrap automobiles every year around the world. If the waste plastics are landfilled or incinerated, resources will be wasted and the environment will be polluted. Through recycling and reuse, the use of virgin plastics can be greatly reduced, and the dependence on non-renewable resources such as petroleum can be reduced. The use of recycled plastics in automobile plastic parts is building a new ecological industry of resource conservation and environmental friendliness.

[0003] The plastic center control frame is a large interior part, usually 1-1.2 meters long, and adopts a thin-walled structure (wall thickness 2.5-3.5 mm) to achieve lightweight. During the demolding and handling after injection molding, the center control frame needs to be lifted and moved by a clamp. The center control frame has a complex geometric shape (such as a multi-curved surface shape and a local mounting column structure), and is made of ABS or PC / ABS modified plastic, which has high rigidity and low thermal expansion coefficient to meet the dimensional stability requirements of the instrument panel mounting position.

[0004] The plastic center control frame after demolding and injection molding may have residual stress inside, and the wall thickness is relatively thin, and the length is relatively long. Therefore, a relatively tight clamping method is usually not used during clamping to avoid excessive stress or local stress concentration, which can easily cause structural deformation or surface indentation problems.

[0005] However, when the demolded plastic center control frame is clamped by a flexible suction cup, surface damage and deformation caused by excessive clamping force can be reduced. However, during the clamping and transportation for subsequent processing, the center control frame is clamped and transported for non-linear movement. The flexible clamping may cause the center control frame to twist and deform due to inertia caused by irregular or different movement speeds during movement and transportation. For example, the thin-walled area of the plastic center control frame (such as the area around the instrument panel mounting position) may also be warped due to inertial stress. Since this area requires high precision, if this problem is not solved in time, it will affect the rework adjustment rate during subsequent assembly of the plastic center control frame. SUMMARY

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0040] Embodiment one: please refer to Figures 1-4 The application provides a technical scheme: a plastic part processing device for automobile interior decoration, which comprises a conveyor 1, a driving assembly 5 is fixedly connected to the outer wall of the conveyor 1, a sliding rail 6 is arranged at the bottom of the conveyor 1, a slider 9 and a sliding plate 10 are slidably connected to the inner wall of the sliding rail 6, the bottom of the sliding plate 10 is fixedly connected to the top of the slider 9, and a clamping mechanism 3 is arranged at the bottom of the slider 9.

[0041] The clamping mechanism 3 comprises:

[0042] An electromagnetic seat 301 is fixedly connected to the bottom of the slider 9, an arc-shaped sleeve 306 and an arc-shaped moving plate 307 are arranged below the electromagnetic seat 301, a pull rope retractor 312 is fixedly connected to the highest position of the inner wall of the arc-shaped sleeve 306, and a lifting air bag 308 is fixedly connected to the surface of the arc-shaped moving plate 307.

[0043] A pull rope 313 is fixedly connected to the inner wall of the pull rope retractor 312, the top of the lifting air bag 308 is provided with a plastic central control frame 8.

[0044] In use, after a large amount of plastic is recycled, the recycled plastic is processed into powder particles and injection molded, then after the mold is separated, the injection molded plastic central control frame 8 needs to be demolded and taken out, through the positioning of the automatic mechanical arm, the plastic central control frame 8 is grabbed and pushed into the arc-shaped sleeve 306 and the arc-shaped moving plate 307, the pull rope retractor 312 is started, the pull rope 313 is pulled back into the pull rope retractor 312, thereby synchronously sliding the arc-shaped moving plate 307 in the inner wall of the arc-shaped sleeve 306, the pull rope 313 lifts the two arc-shaped moving plates 307 on both sides of the arc-shaped sleeve 306, exposes the opening between the two arc-shaped moving plates 307, and then the plastic central control frame 8 is pushed into the arc-shaped sleeve 306 by the mechanical arm clamping, then the pull rope retractor 312 is controlled to lower the pull rope 313, and the arc-shaped moving plate 307 is automatically reset and closed, so that the plastic central control frame 8 is stably fixed in the arc-shaped sleeve 306, precise assembly is completed, and at the same time, the plastic central control frame 8 falls on the lifting air bag 308 full of air under the action of gravity, the air in the lifting air bag 308 and the deformable material thereof make the lifting air bag 308 completely fit the perforations (instrument panel installation position and surrounding symmetrical hole position) of the plastic central control frame 8, the plastic central control frame 8 is supported, and then the driving assembly 5 is started to make the slider 9 start to slide in the inner wall of the sliding rail 6, so that the slider 9 moves to the specified position together with the arc-shaped sleeve 306 and the plastic central control frame 8 below, and the lifting and buffering effects of the lifting air bag 308 effectively avoid the situation that the plastic central control frame 8 is clamped by a hard clamping piece during transportation, the temperature of the plastic central control frame 8 is relatively high when the plastic central control frame 8 is just demolded, thermal stress and mechanical stress are superimposed, and the risk of deformation is further aggravated;

[0045] The multi-point lifting air bag 308 fits the lifting design, not only disperses the stress, but also reduces the local stress concentration through uniform stress, and the flexible buffer effect of the material of the lifting air bag 308 effectively absorbs the vibration in the transportation process, further reduces the deformation probability, and compared with the traditional suction cup clamping, the lifting air bag 308 lifting avoids the local stress concentration caused by point contact of the suction cup clamping through larger and more fitted contact area and uniform stress, reduces the bending and warping problems caused by inertia;

[0046] And when the transmission speed changes slightly, for example, when acceleration starts transmission or deceleration gradually stops, the wall thickness of the vertical surface of the plastic central control frame 8 is thin, and if the traditional clamping is tightened, the position not clamped will be easily deformed due to the inertia problem in the acceleration and deceleration state, and the two arc-shaped moving plates 307 and the lifting air bag 308 are combined to present an arc shape, allowing the plastic central control frame 8 to have a certain swinging range on the lifting air bag 308, so when the vertical surface is subjected to an inertial force, the deformation problem of the unclamped position caused by inertia can be alleviated by slight swinging, and if the plastic central control frame 8 is clamped in all directions, the clamping structure will be too complex, and different types of automobile plastic central control frames 8 are difficult to adapt, and the application is too limited.

[0047] Embodiment two: please refer to Figures 1-8 On the basis of embodiment one, the application provides a technical solution: the transmission machine 1 is fixedly connected with the bracket 7 on both sides, the bracket 7 is fixedly connected with the protective rod 2 on one side, the electromagnetic seat 301 is slidingly connected with the magnetic ball 302 at the bottom, the magnetic ball 302 is fixedly connected with the fixed plate 303 at the bottom, the inner wall of the arc-shaped sleeve 306 is slidingly connected with the outer wall of the arc-shaped moving plate 307, the lifting air bag 308 is fixedly connected between the inner wall of the arc-shaped moving plate 307, the injection machine 310 is fixedly connected with the air outlet 311 at the top, and the injection machine 310 is used for injecting air into the lifting air bag 308.

[0048] The end of the pull rope 313 away from the pull rope retractor 312 is fixedly connected with one end of the arc-shaped moving plate 307 through the connecting piece 316, the two sides of the pull rope retractor 312 are fixedly connected with the open sleeve 314, the top of the arc-shaped sleeve 306 is fixedly connected with the connecting block 305, the top of the connecting block 305 is fixedly connected with the first spring 304, one end of the first spring 304 is fixedly connected with the bottom of the fixed plate 303, the number of the arc-shaped moving plate 307 on the inner wall of the arc-shaped sleeve 306 is two, and the two arc-shaped moving plates 307 are symmetrically arranged in the inner wall of the arc-shaped sleeve 306, and the lifting air bag 308 is fixedly connected with the horizontal air bag 309 on one side.

[0049] The inner wall of the arc-shaped sleeve 306 is provided with a sliding groove 315, the arc-shaped moving plate 307 is slidably connected in the inner wall of the arc-shaped sleeve 306 through the sliding groove 315, the number of the pull ropes 313 is two, and one end of each of the two pull ropes 313 is fixedly connected with the top end of the corresponding arc-shaped moving plate 307.

[0050] The top center of the connecting block 305 is fixedly connected with a hollow telescopic rod 318, the top end of the hollow telescopic rod 318 is hingedly connected to the bottom of the fixed plate 303 through a hinge ball 317, the number of the lifting air bags 308 is two, the side close to each other of the two lifting air bags 308 is fixedly connected with a transverse air bag 309 respectively, the elastic force of the transverse air bag 309 is greater than that of the lifting air bag 308, and the inner wall of the hollow telescopic rod 318 is provided with an air hole 319;

[0051] When the slider 9 moves in the sliding rail 6 for a long distance to transport the plastic central control frame 8, it is easy to encounter a turning transmission path, and when encountering the turning moving path, the magnetic ball 302 below the slider 9, the fixed plate 303 and the plastic central control frame 8 held by the magnetic ball 302 will deviate from the center of the curve due to inertia, if the plastic central control frame 8 is fixed and cannot be tilted, the plastic central control frame 8 will be subjected to the inertial force of the transverse deviation from the center of the curve, causing the rapid change of the internal stress of the plastic central control frame 8, and the internal stress and thermal stress are superimposed in the just demolding state, which is easy to cause deformation, at this time, through the design of the magnetic ball 302 and the electromagnetic seat 301, the electromagnetic seat 301 is provided with a sensor inside to control the current in real time, so that the electromagnetic adsorption force can be adjusted, the adsorption force and the rotation flexibility of the magnetic ball 302 are balanced, the magnetic ball 302 is adsorbed in the inner wall of the electromagnetic seat 301 through electromagnetic adsorption, the rolling balls embedded in the inner wall of the electromagnetic seat 301 are used to realize the free rotation of the magnetic ball 302 in the inner wall of the electromagnetic seat 301, and the rolling balls embedded in the inner wall of the electromagnetic seat 301 change the sliding friction between the electromagnetic seat 301 and the magnetic ball 302 into rolling friction, avoiding the problem that the friction between the two affects the rotation when the electromagnetic seat 301 automatically adjusts the magnetic size adsorption force, and the fixed plate 303 connected below the magnetic ball 302 and the first spring 304 pull the connecting block 305, the arc-shaped sleeve 306 and the arc-shaped moving plate 307 to make the plastic central control frame 8 rotate synchronously with the curve, effectively balance the transverse inertial force, avoid the sudden change of the internal stress, ensure the stability of the plastic central control frame 8 in the turning process, and reduce the risk of deformation;

[0052] Thus, compared with the traditional flexible clamping of the suction cup type, the plastic central control frame 8 is rotated together with the turning process through the maximum multi-point large-area wrapping vertical support, the horizontal stress of the plastic central control frame 8 is uniformly changed into vertical stress, the clamping mode of the lifting air bag 308 is maximized to avoid the problem of transverse internal stress generated in the plastic central control frame 8;

[0053] The first spring 304 connected between the fixed plate 303 and the connecting block 305 can play the role of the connecting block 305 and the arc-shaped sleeve 306, and can adjust the distance between the connecting block 305 and the fixed plate 303 through elastic deformation when turning, and can lift the instantaneous pressure generated between the air bag 308 and the plastic central control frame 8 when suddenly turning, so that the plastic central control frame 8 and the air bag 308 are synchronously displaced downward through the elongation of the first spring 304, so as to release the instantaneous force to a certain extent, so that the instantaneous impact force is effectively relieved, and the deformation caused by the instantaneous high pressure is avoided.

[0054] When turning into a straight line after moving through the bending core, the plastic central control frame 8 will gradually return to normal under the action of its own gravity and inertia, and the first spring 304 will also return to its original position under the action of its own elastic force, so as to ensure that the plastic central control frame 8 and the air bag 308 are reattached, maintain stable support, continue to reduce the risk of deformation, and when the connecting block 305 is pulled back by the first spring 304, the hollow telescopic rod 318 between the connecting block 305 and the fixed plate 303 changes the distance between the connecting block 305 and the fixed plate 303 through the opening of the surface air hole 319, so as to limit the problem of unstable stretching or compression, ensure that the whole transmission process is as smooth as possible, and reduce the deformation problem caused by the change of pressure between the plastic central control frame 8 and the air bag 308.

[0055] Embodiment three: please refer to Figures 1-11 On the basis of the first embodiment and the second embodiment, the application provides a technical solution: the top inner wall of the arc-shaped moving plate 307 is provided with an adjusting mechanism 4, the adjusting mechanism 4 comprises an arc-shaped telescopic plate 401, one end of the arc-shaped telescopic plate 401 away from the arc-shaped moving plate 307 is fixedly connected with a connecting block 402, the top of the connecting block 402 is fixedly connected with the inner wall of the arc-shaped sleeve 306, the other end of the arc-shaped telescopic plate 401 is fixedly connected with the top end of the arc-shaped moving plate 307, and the inner wall of the arc-shaped telescopic plate 401 is provided with a second spring.

[0056] The top of the arc-shaped sleeve 306 is provided with a communication hole 403, the inner wall of the sealing cavity 405 is slidably connected with a sliding column 406, and the inner wall of the sealing cavity 405 is in communication with the inner wall of the communication hole 403 through the inside of the connecting block 305.

[0057] The end of the sliding column 406 away from the connecting block 305 is fixedly connected with a push plate 407, the push plate 407 is a circular disc structure, one side of the connecting block 305 is fixedly connected with a distance sensing processor 408, the distance sensing processor 408 is a circular sleeve structure, and one side of the distance sensing processor 408 is fixedly connected to the outer wall of the connecting block 305.

[0058] If the work efficiency needs to be accelerated to cope with the output of the plastic control frame 8 in the factory, the staff will often use faster transmission speed, at this time when the faster speed passes through the center of the turn, the lifting air bag 308 and the plastic control frame 8 are easy to produce a certain shaking due to air resistance, causing the plastic control frame 8 originally stably placed on the lifting air bag 308 to produce a slight deviation, and the pressure between the lifting air bag 308 and the plastic control frame 8 increases more synchronously, at this time the air in the lifting air bag 308 is squeezed to both sides, on the one hand, the lateral thrust of the air will produce a horizontal component force on the arc-shaped moving plate 307, on the other hand, because the lifting air bag 308 and the arc-shaped moving plate 307 are arc-shaped, when they are subjected to vertical downward pressure, they will also produce a horizontal pushing component force on the arc-shaped moving plate 307, so that each arc-shaped moving plate 307 will slide away from each other to a certain extent under the action of this force, and will overcome the deformation of the second spring in the inner wall of the arc-shaped expansion plate 401, while the second spring will not deform, so that the two arc-shaped moving plates 307 are opened to a certain gap, and the gap is far from enough to make the plastic control frame 8 separate from the support of the lifting air bag 308, at the same time, the deformation of the lifting air bag 308 and the arc-shaped moving plate 307 will change from lifting to lateral extrusion, realizing the dynamic balance of lifting and lateral support, ensuring that the plastic control frame 8 will not shake left and right when turning at high speed;

[0059] When the pressure between the lifting air bag 308 and the plastic control frame 8 increases instantaneously, the lateral air bag 309 with greater elastic force will be pushed out by the air pressure in the lifting air bag 308, because the pressure deformation threshold of the lateral air bag 309 is higher than that of the lifting air bag 308, when the air pressure in the lifting air bag 308 rises above the preset threshold of the pressure deformation of the lateral air bag 309, the gas will flow into the lateral air bag 309 to make it expand, otherwise the lateral air bag 309 will remain in a contracted state, at this time the lateral air bag 309 further clamps the two sides of the plastic control frame 8 when it expands, thereby effectively fixing the position of the plastic control frame 8 and preventing it from deviating during high-speed movement, to specially cope with the additional pressure and shaking between the plastic control frame 8 and the lifting air bag 308 due to the increase in speed, ensure the stability of the plastic control frame 8 during high-speed movement, reduce the risk of deformation caused by speed increase, and improve the overall work efficiency. At the same time, the elastic force design of the arc-shaped expansion plate 401 and its second spring can be adjusted according to actual needs, and can flexibly cope with different working conditions, as well as different types and weights of plastic control frames 8;

[0060] And in the state of normal speed transportation, because there is no excessive speed, the pressure between the lifting air bag 308 and the plastic central control frame 8 is not enough to push the second spring in the arc-shaped telescopic plate 401 to deform, so in the state of normal movement transportation, the arc-shaped moving plate 307 and the lifting air bag 308 will not slide in the inner wall of the sliding groove 315, which means that it will not be wrapped on the side of the plastic central control frame 8, which avoids the problem that the larger area on the side is wrapped, which makes it more difficult for the residual heat in the plastic central control frame 8 to dissipate, and causes stress changes and deformations due to temperature differences between the plastic parts at other positions of the plastic central control frame 8. At the same time, it also reduces the extrusion force on the easily deformed position of the plastic central control frame 8. Through the single vertical lifting support provided by the lifting air bag 308 in the normal state, it does not provide unnecessary clamping, which reduces the problem of plastic central control frame 8 being extruded and deformed due to excessive clamping in multiple directions;

[0061] And in the state of high-speed movement, when the two arc-shaped moving plates 307 are separated from each other, the hydraulic oil in the arc-shaped telescopic plate 401 will be squeezed, enter the connecting block 305 through the communication hole 403 at the top of the sliding groove 315, and push out the sliding column 406 and the push plate 407 connected to the inner wall of the connecting block 305. The annular distance sensor processor 408 can recognize the change in the distance between the mutually parallel push plates 407 through optical sensing, process the distance information, and control the gas injection amount of the gas injection machine 310 in the lifting air bag 308 in real time according to the different distances. Once in the state of high-speed movement, when the two arc-shaped moving plates 307 are separated from each other, the hydraulic oil in the arc-shaped telescopic plate 401 is quickly replenished to the connecting block 402, ensuring the stable movement of the sliding column 406 and the push plate 407. The distance sensor processor 408 accurately adjusts the gas injection of the gas injection machine 310 to the lifting air bag 308 to increase the clamping force on the unstable plastic central control frame 8 to match the sliding of the arc-shaped moving plate 307 and the lifting air bag 308 to increase the clamping force on the bottom and both sides of the plastic central control frame 8. Therefore, not only can the clamping position be changed by moving the arc-shaped moving plate 307 and the lifting air bag 308, but also can the clamping force of the lifting air bag 308 on the plastic central control frame 8 be increased as the speed increases and the inertia increases when passing through the center of the bend, thereby avoiding the problem of greater deformation risk of the plastic central control frame 8 due to extremely unstable shaking in the state of high-speed movement. The advantages of the two are much greater than the disadvantages, so as to adaptively dynamically adjust to meet the stability requirements of the easily deformed plastic central control frame 8 in more high-speed movement scenarios, and ensure its reliable operation under complex working conditions;

[0062] The hydraulic oil is used for pushing the sliding column 406 and the push plate 407 with small mass to move when the arc-shaped telescopic plate 401 is telescoped. The pressure of the hydraulic oil in the arc-shaped telescopic plate 401 is very small when it is squeezed, and it will not interfere with the expansion and contraction of the elastic force of the second spring.
