Description

Technical Field

[0001] The invention belongs to the technical field of automobile parts production, and relates to a high-efficiency film pasting device and method. Background Art

[0002] As the name suggests, film pasting is to stick the film on the structure where it is required. For example, in the production process of the B-pillar of some new energy vehicles in my country, it is necessary to stick a protective film on the outer shell (plastic) of the B-pillar to protect the B-pillar outer shell and prevent dust, so that it can remain bright during storage, transportation and assembly. The protective film is usually torn off before the car is used.

[0003] The film attached to the B-pillar shell is electrostatically adsorbed, not glue, etc., so that tax reduction residues can be reduced. At the same time, the film is usually slightly smaller than the B-pillar shell. Specifically, there is a certain distance between the periphery of the film and the edge of the B-pillar shell. This can not only reduce the difficulty of film application (that is, there is no need to completely align the edge of the film with the edge of the B-pillar shell), but also prevent the film from peeling off from the B-pillar shell during storage, transportation and assembly of the B-pillar shell.

[0004] The film to be pasted has a certain hardness (but not hard), and is usually electrostatically adsorbed on the base film (flexible and thin); when pasting the film, the back film needs to be separated from the base film and then transferred to the B-pillar shell. Summary of the invention

[0108] The present invention also provides a method for film pasting using a high-efficiency film pasting device as described in any one of the above items, comprising the following steps:

[0109] S 1, placing the workpiece into the support groove 9;

[0110] S2, the first driving mechanism drives the movable seat 8 to move toward the -X direction, so that the X end of the workpiece is located below the stripping plate 7;

[0111] S3, the motor drives the winding roller 6 to rotate, winds the base film 4, and at the same time pulls the unwinding roller 3 to rotate through the base film 4;

[0112] S3, the film to be attached 5 and the base film 4 are separated at the X end of the peeling plate 7, and the base film 4 moves toward the -X direction, the film to be attached 5 moves toward the X direction, and the film to be attached 5 is adsorbed on the top of the workpiece;

[0113] S4, the unwinding roller 3 continues to pull the base film 4, and the first driving mechanism drives the movable seat 8 to move in the X direction, so that the film 5 to be laminated is continuously laminated to the top of the workpiece;

[0114] S5, when the lamination of a section of the film 5 is completed, the winding roller 6 stops rotating, the movable seat 8 moves to the X end, and the worker removes the workpiece with the film laminating completed and places the next workpiece.

[0115] The present invention provides an efficient film laminating device. When laminating, a worker first manually places the workpiece into the support groove 9; then the first driving mechanism drives the movable seat 8 to move toward the -X direction, and stops after the X end of the workpiece is located below the peeling plate 7; the motor drives the winding roller 6 to rotate, winds the base film 4, and at the same time pulls the unwinding roller 3 to rotate through the base film 4 (wherein there is a certain friction force between the rolled film and the unwinding roller 3, and the friction force can be the friction force between the film roll and the outer wall of the unwinding roller 3, or the friction force between the film roll plate on the outer wall of the unwinding roller 3 and the two sides of the film roll; and the film roll can release the film when it is subjected to tension, but can stop stably and quickly when it is not subjected to tension);

[0116] The film to be attached 5 is separated from the base film 4 at the X end of the stripping plate 7, and the base film 4 moves toward the -X direction, and the film to be attached 5 moves toward the X direction, and the film to be attached 5 is adsorbed on the top of the workpiece; wherein the film to be attached 5 has a certain strength relative to the base film 4, so that it can change direction with the base film 4 between the guide rollers, but because the X end of the stripping plate 7 is pointed, the film to be attached 5 can be separated from the base film 4 by itself, and in the subsequent movement of the base film 4, the film to be attached 5 can extend forward under the action of its own strength until it is attached to the top of the workpiece;

[0117] Then the unwinding roller 3 continues to pull the base film 4, and the first driving mechanism drives the movable seat 8 to move in the X direction, so that the film to be pasted 5 continues to be pasted to the top of the workpiece, and the movement of the workpiece and the movement of the film to be pasted 5 are carried out simultaneously and synchronously, and the speeds of the two activities are matched, so that the film to be pasted 5 can be stably and fully pasted and electrostatically adsorbed on the top of the workpiece; when a section of the film to be pasted 5 is completed, the winding roller 6 stops rotating (all automatically controlled by the computer), the movable seat 8 moves to the X end, and the worker removes the workpiece with the film pasted and places the next workpiece.

[0118] At the very beginning of the processing, the worker first needs to put a new film roll on the unwinding roller 3, wherein preferably there is a plastic or cardboard support tube in the middle of the film roll (i.e. the film roll is wrapped around the outer wall of the support tube); one form is that there is a certain friction between the inner wall of the support tube and the outer wall of the unwinding roller 3 (stationary and not rotating), and the support tube uses this friction to enable the film roll to release the film when it is subjected to tension, and not release the film when it is not subjected to tension; at the same time, there are stop plates at both ends of the support tube, and the stop plates are detachably connected to the unwinding roller 3 by bolts (the stop plate has a cylinder outside, the bolts are threadedly connected to the cylinder, and the ends of the bolts can contact the unwinding roller 3). Another form is that there is friction between the stop plates on both sides and the edges of the film roll, so that the film roll can release the film when it is subjected to tension, and not release the film when it is not subjected to tension.

[0119] After the film roll is installed on the unwinding roller 3, the free end of the film is in a free state; then the worker manually turns the handle on the driving screw 34 or uses a motor to drive the driving screw 34 to rotate (the figure is only for illustration and does not represent the actual structure), wherein the driving screw 34 also passes through the support plate 47 and the stabilizing seat 38 (not threaded). When the driving screw 34 rotates, the driving lifting seat 35 moves in a direction away from the supporting vertical plate 2, and the lifting seat 35 drives the outer movable plate 19 downward through the driving arm 36.

[0120] When the outer movable plate 19 moves downward, under the joint action of the first inner horizontal groove 14 and the first outer inclined groove 20, the connecting column 24 connected to the first guide roller 11 moves horizontally toward the X direction; under the joint action of the inner inclined groove 17 and the outer horizontal groove 23, the connecting column 24 connected to the second guide roller 12 moves toward the -X direction, and the height becomes lower and lower; under the joint action of the second inner horizontal groove 15 and the second outer inclined groove 21, the connecting column 24 connected to the third guide roller 13 moves horizontally toward the -X direction; under the joint action of the third inner horizontal groove 16 and the third outer inclined groove 22, the linkage rod 29 moves horizontally toward the -X direction;

[0121] When the outer movable plate 19 moves to the lowest state, the worker only needs to pull the free end of the film vertically downward. At this time, the first guide roller 11 and the fixed guide roller 10 are located on the X side of the film, and the second guide roller 12 and the third guide roller 13 and the stripping plate 7 are all located on the -X side of the film; after that, the worker only needs to pass the free end of the film around the bottom of the stripping plate 7, pull the film in the -X direction, and fix the end of the film to the winding roller 6 (for example, the free end of the film is fixedly connected to the winding roller 6 through conventional structures such as tape or clips). At this time, waste of the film 5 to be pasted will be generated (such as the film 5 to be pasted wrapped on the winding roller 6 and the film 5 to be pasted located under the stripping plate 7), or the worker can also manually tear off this part of the film 5 to be pasted to avoid affecting the subsequent normal winding.

[0122] After the end of the film is fixedly connected to the winding roller 6, the screw rod 34 is driven to rotate in the opposite direction and the outer movable plate 19 is raised, so that the outer movable plate 19 reaches the state when the film is applied (i.e., the state of part [1]). When applying the film, the winding roller 6 is driven by the motor to rotate, and the base film 4 pulls the film to move, so that after the film is released from the film roll, it passes around the first guide roller 11, the second guide roller 12, the third guide roller 13, the peeling plate 7, the fixed guide roller 10 and the unwinding roller 3 in sequence. After the film passes through the first guide roller 11, the second guide roller 12 and the third guide roller 13, it can knead the film to be pasted 5 and the base film 4, thereby increasing the separability between the film to be pasted 5 and the base film 4, but at the same time does not affect the shape and strength of the film to be pasted 5; at the same time, since the film to be pasted 5 is wound on the film roll, when it is pulled around the first guide roller 11, the second guide roller 12 and the third guide roller 13, it can restore its shape, so that after being electrostatically adsorbed on the surface of the workpiece, it can have a smaller internal stress, thereby better fitting to the surface of the workpiece.

[0123] After being guided by the fixed guide roller 10, the film moves in a form of being attached to the upper surface of the peeling plate 7, so that when the film 5 to be attached is separated from the base film 4, there is a sufficiently large angle between the film 5 to be attached and the base film 4, so that the film 5 to be attached can be better separated from the base film 4. At the same time, the peeling plate 7 is tilted downward, and when the workpiece moves to the -X end, the workpiece is slightly lower than the bottom of the X end of the peeling plate 7, so the film 5 to be attached needs to be tilted downward to be normally adsorbed on the top of the workpiece.

[0124] When the outer movable plate 19 is moving, the stabilizing ring 25 on the outer wall of the connecting column 24 is movably engaged in the corresponding two strip grooves 18, and the anti-slip ring 26 is movably attached to the two sides of the outer movable plate 19, so that the connecting column 24 has sufficient strength to support the first guide roller 11, the second guide roller 12 and the third guide roller 13 (the end of the connecting column 24 is inserted into the first guide roller 11, the second guide roller 12 and the third guide roller 13 to a certain depth, and the first guide roller 11, the second guide roller 12 and the third guide roller 13 and the connecting column 24 can rotate relative to each other to reduce the resistance of the membrane movement), and can also better maintain the activity stability of the connecting column 24. At the same time, since there is a certain distance between the outer movable plate 19 and the supporting vertical plate 2, when the connecting column 24 is driven by the outer movable plate 19 and the supporting vertical plate 2, it can better prevent the connecting column 24 from being deformed and better avoid being stuck and unable to move.

[0125] At the same time, when the outer movable plate 19 is raised or lowered, the linkage rod 29, the anti-slip portion 30 and the sliding portion 28 can also ensure that the stripping seat can move; but the difference is that the stripping seat, the sliding seat 27 and the linkage rod 29 are all fixedly connected, and the sliding seat 27 is a rectangular parallelepiped, so that the stripping plate 7 can only move horizontally but cannot rotate. At the same time, the stabilizing portion 39 at the other end of the stripping seat is supported by the stabilizing groove 40, so that the stripping plate 7 can be stably translated.

[0126] There are two movable seats 8 between the two opposite support plates 47, and the movement directions of the two movable seats 8 are opposite, that is, when one of the movable seats 8 is at the X end of its trajectory, the other movable seat 8 is at the -X end of its trajectory. In this way, when one movable seat 8 is laminating, the other movable seat 8 can remove the workpiece with the film pasted and replace it with a new workpiece for laminating, which can greatly improve the efficiency of laminating.

[0127] Specifically, when the workpiece with film just starts to move toward the X direction, the top driving belt 50 moves toward the X direction, so the bottom driving belt 50 moves toward the -X direction at the same time, so that the movable seat 8 for the worker to put and take the workpiece moves toward the -X direction; when the second guide column 69 at the bottom of the movable seat 8 that moves toward the -X direction moves to the first transition groove 52, the guiding effect of the top of the first transition groove 52 and the gravity of the movable seat 8 make the movable seat 8 move downward, and after the second guide column 69 enters the bottom groove 53, the movable seat 8 moves horizontally at a lower height; at the same time, the movable seat 8 with the film pasted on the top moves toward the X direction at a higher height; when the second guide column 69 enters the second top groove 55 through the second transition groove 54, the top of the movable seat 8 returns to the highest height (the same height as the top of the movable seat 8 that moves toward the X direction).

[0128] Afterwards, the movable seat 8 continues to move inward, and at a certain node, the upper surface of the lifting part 60 contacts the lower side of the drag reduction cylinder 64, and under the driving action of the lifting part 60, the drag reduction cylinder 64, the horizontal part 63, the vertical part 62, the anti-slip seat 44, the bonding roller 45 and the bonding arm 42 all move upward until the drag reduction cylinder 64 transitions from the lifting part 60 to the top of the lifting member 58. At this time, the bonding roller 45 is higher than the top of the workpiece and does not affect the position stability of the workpiece.

[0129] When the movable seat 8 moves to the innermost end, the drag reduction cylinder 64 just passes through the descending hole 59, and the laminating roller 45 moves downward under the elastic force of the first elastic member 46, and the lower side of the laminating roller 45 contacts the top of the movable seat 8. Then the computer controls the movable seat 8 to move outward (preferably stops for a short period of time for the worker to put and take the workpiece at the X end at this time), and drives the winding roller 6 to rotate, so that the film 5 to be laminated is laminated on the top of the workpiece; at the same time, as the movable seat 8 moves, the lower side of the laminating roller 45 can apply a downward pressure, and the film 5 to be laminated is better laminated on the surface of the workpiece. The shape of the laminating roller 45 matches the shape of the workpiece. For example, if the middle part of the workpiece bulges upward, the middle part of the laminating roller 45 is concave downward; or the outer surface of the laminating roller 45 has a deformation cylinder with a certain thickness, so that workpieces of different shapes can be laminated.

[0130] During the outward movement of the movable seat 8, the vertical portion 62 is located between the free end of the lifting member 58 and the outer side of the movable seat 8, so the vertical portion 62 does not affect the normal movement of the movable seat 8; at the same time, the drag reduction cylinder 64 is higher than the extension portion 57, so the elastic force of the first elastic member 46 can be borne by the workpiece, ensuring the lamination effect on the film and the workpiece. When the movable seat 8 continues to move, at some point the drag reduction cylinder 64 hits the lower side of the lifting portion 60, and drives the lifting portion 60 to rotate upward, so that the movable seat 8 can normally pass over the laminating roller 45. After the lifting part 60 passes over the drag reduction cylinder 64, the laminating roller 45 descends until the anti-slip disc 43 contacts the top of the laminating frame 41, and the lifting part 60 rotates downward under the action of gravity until the anti-rotation member 61 contacts the -X end of the lifting member 58, waiting for the next use; at the same time, when the upper side of the lifting part 60 contacts the drag reduction cylinder 64, the anti-rotation member 61 can also provide resistance to prevent the lifting part 60 from rotating downward. The driving belt 50 at the top is used to drive the movable seat 8 to move, but the gravity of the movable seat 8 is mainly or entirely transmitted to the support plate 47 through the connecting seat 65 and the first guide column 66. At the same time, although the thickness of the two movable seats 8 is equal, and the first top groove 51 and the second top groove 55 are both lower than the upper groove 56, the compensation seat 67 has a certain thickness. Therefore, when the second guide column 69 is located in the first top groove 51 or the second top groove 55, the compensation seat 67 can raise the height of the movable seat 8 upward, so that the two movable seats 8 can normally receive the film 5 to be pasted and be affected by the laminating roller 45. In addition, the second guide column 69 can not only transmit the gravity of the movable seat 8 outward, but also be guided by the first transition groove 52, the second transition groove 54, etc., so as to control the lifting and lowering of the movable seat 8; at the same time, the lifting rods 68 at the bottom of the movable seat 8 are each limited by the vertical cylinder 71, so that the movable seat 8 can maintain stable vertical lifting and lowering without angular deviation. At the same time, anti-rotation strips (not shown in the figure) are horizontally arranged on the inner sides of the two support plates 47. The two sides of the translation plate 70 are movably fitted on the inner sides of the support plates 47, the two sides of the bottom are movably fitted on the tops of the two anti-rotation strips, and the two sides of the top are connected to the two driving belts 50.

[0131] When the film has a certain length before and after passing through the stripping plate 7, it is easy to cause the film to be offset; at this time, there is a limit plate 80 on the top of the stripping plate 7 to limit the two sides of the film, so that the film can be corrected to a certain extent, so that the film can be better aligned with the workpiece; in the actual production process, the size of the film is slightly smaller than the workpiece, and the two are not required to be completely aligned. Therefore, although the film is flexible and it is difficult to accurately correct it, the limit plate 80 can still correct it to a certain extent, thereby improving the yield rate. At the same time, there is a sinking groove 79 on the top of the matching plate 74 and the stripping plate 7, and at the same time, the bottom of the limit plate 80 is attached to the bottom of the sinking groove 79, so that when the film passes through the limit plate 80, there is a certain height difference between it and the bottom of the limit plate 80, that is, the film is close to the bottom of the limit plate 80, which can better prevent the film from being stuck at the bottom of the limit plate 80. At the same time, since there will be workpieces and films of different sizes during processing, it is necessary to replace the movable seat 8 and adjust the spacing between the limit plates 80. The movable seat 8 includes a base and an adjustment seat located on the top of the base (the base is fixed to the extension part 57, the lifting member 58, the connecting seat 65, the compensation seat 67, etc.), a countersunk hole is opened on the top of the adjustment seat, a bolt passes through the countersunk hole, and the base and the adjustment seat are connected by bolts, and the support groove 9 is located at the top of the adjustment seat. In this way, when laminating different workpieces, you only need to remove the bolts and then replace the new adjustment seat. The countersunk holes on different adjustment seats are the same, and the thickness is also the same, but the depth and shape of the support groove 9 need to be adapted according to the shape of the workpiece. At the same time, the bolt is lower than the top of the adjustment seat, which does not affect the normal use of the laminating roller 45.

[0132] When adjusting the position of the limit plate 80, the worker only needs to operate the unlocking protrusion 89 outward with one hand, and further compress the second elastic member 86, and separate the locking portion 87 from the first adjustment column 75. At this time, the first adjustment column 75 is in an empty state, and the worker only needs to adjust the first adjustment column 75. At this time, the first adjustment column 75 drives the adjustment belt 77 (preferably a gear belt) to rotate, and at the same time drives the two linkage portions 82 to move; since the two linkage portions 82 are connected to the two sides of the adjustment belt 77, the two linkage portions 82 can be close to or away from each other at this time, so that not only the position of the limit plate 80 can be adjusted, but also the position of the middle part of the two limit plates 80 can be always aligned with the position of the middle part of the peeling plate 7, thereby ensuring the correction effect. Since the limiting plate 80 is in the shape of a long strip, and the bottom of the limiting plate 80 has two convex-shaped sliding seats 81, and the two sliding seats 81 are respectively movably engaged in the two adjustment slots 78, the two sliding seats 81 can well prevent the limiting plate 80 from angular deviation, thereby ensuring the correction and guiding effect. In actual operation, if the limiting plate 80 is not convenient to automatically change its position (for example, it is stuck in the adjustment slot 78), the worker can also push or pull the limiting plate 80 manually from the outside.

[0133] After the positions of the two limit plates 80 are appropriate, the worker releases the unlocking protrusion 89. At this time, under the thrust of the second elastic member 86, the locking arm 85 and the locking portion 87 move toward the first adjustment column 75, and the anti-rotation portions 88 at both ends of the locking portion 87 are attached to the outer wall of the first adjustment column 75. The anti-rotation portions 88 are flexible (for example, made of rubber or silicone material), and the free end of one anti-rotation portion 88 (named a anti-rotation portion 88) is located on the counterclockwise side of its connection end, and the free end of the other anti-rotation portion 88 (named b anti-rotation portion 88) is located on the clockwise side of its connection end; in this way, if the first adjustment column 75 has a tendency to rotate counterclockwise during use, it also has a tendency to drive the free end of the b anti-rotation portion 88 to deform. However, due to the action of the second elastic member 86, the position of the locking portion 87 is relatively stable, and the b anti-rotation portion 88 is not deformed. 8 is also difficult to be compressed and cannot be deformed, so the first adjustment column 75 can be prevented from rotating counterclockwise; similarly, if the first adjustment column 75 has a tendency to rotate clockwise at this time, the anti-rotation portion 88 can also better prevent it from rotating (usually the force of spontaneous rotation is very small, so only an appropriate self-locking effect is needed to fully ensure its position stability); in this way, the anti-rotation portions 88 on both sides can well prevent the first adjustment column 75 from rotating clockwise or counterclockwise, thereby ensuring the position stability of the first adjustment column 75 and also ensuring the limiting effect of the two limiting plates 80 on the membrane.
