Detailed Description

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, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1-3, a method of encapsulating a workpiece 10 is disclosed. The adhesive tape is coated on a first surface 11 and a second surface 12 which are oppositely arranged on the workpiece 10 and a third surface 13 which connects the first surface 11 and the second surface 12; specifically, a first end 21 of the tape is applied to the first face 11, a second end 22 is applied to the second face 12, and an intermediate portion 23 is applied to the third face 13.

For convenience of description, the extending direction of the adhesive tape along the first surface 11, the third surface 13 and the second surface 12 is referred to as the length direction of the adhesive tape; and the direction in which the tape extends along the first surface 11 (or the second surface 12, or the third surface 13) is referred to as the width direction of the tape. Meanwhile, the width direction of the tape corresponds to the length direction of the first surface 11, the second surface 12 or the third surface 13, and the width direction of the first surface 11, the second surface 12 or the third surface 13 is perpendicular to the length direction.

When the workpiece is encapsulated, the width of the adhesive tape is slightly longer than the length of the encapsulating surface (i.e. the first surface 11, the second surface 12 or the third surface 13) of the workpiece 10, and at this time, the extended part of the adhesive tape protrudes out of the workpiece 10 and is adjacent to the fourth surface 14 of the first surface 11, the second surface 12 and the third surface 13; or, the extended adhesive tape protrudes from the workpiece 10 and is adjacent to the fourth surface 14 and the fifth surface 15 of the first surface 11, the second surface 12 and the third surface 13; that is, the tape may protrude from only one side or both sides when encapsulated. Meanwhile, since the adhesive surfaces of the adhesive tapes are attached to the first surface 11, the second surface 12 and the third surface 13, the adhesive surfaces of the adhesive tapes protruding from the fourth surface 14 face the fourth surface 14; the protruding adhesive tape can be directly adhered to the fourth surface 14 when folded back toward the fourth surface 14.

Referring to fig. 4-6, in order to treat the portion of the tape protruding from the workpiece 10, the present application discloses a hemming device comprising: a first folding mechanism 100 for folding the first end portion 21 of the adhesive tape protruding from the workpiece 10; a second folding mechanism 200 for folding the second end 22 of the adhesive tape protruding from the workpiece 10; a third folding mechanism 300 for folding back the intermediate portion 23 of the adhesive tape protruding from the work 10. Wherein, the first folding mechanism 100 is arranged opposite to the first surface 11; the second hemming mechanism 200 is disposed opposite to the second surface 12, and the third hemming mechanism 300 is disposed opposite to the third surface 13.

When the adhesive tape protrudes from the workpiece 10 on only one side, the folding device may be disposed opposite to the fourth surface 14 of the workpiece to fold the first end portion 21 of the adhesive tape onto the fourth surface 14 by the first folding mechanism 100; folding the second end 22 of the tape over the fourth face 14 by the second folding mechanism 200; the third end 23 of the tape is folded over to the fourth face 14 by the third folding mechanism 300.

When both sides of the adhesive tape protrude from the workpiece 10, in an embodiment, the adhesive tape protruding from one side may be turned over onto the workpiece 10 by the edge folding device, and then the workpiece may be turned over, so that the other side to be folded faces the edge folding device, so that the edge folding device can turn over the adhesive tape protruding from the other side onto the workpiece 10. In another embodiment, the adhesive tape protruding from one side may be turned over to the workpiece 10, and then the folding device may be moved so as to face the other side to be folded and turn the adhesive tape protruding from the other side over to the workpiece 10. Still other embodiments are described in detail below.

In one embodiment, referring to fig. 4, the first face 11 and the second face 12 are arranged opposite to each other in the vertical direction, the first face 11 is on the top, the second face 12 is on the bottom, and the third face 13 is on the right; the fourth surface 14 vertically connects the first surface 11, the second surface 12, and the third surface 13, and is a surface facing inward of the vertical paper; the fifth surface 15 directly connects the first surface 11, the second surface 12, and the third surface 13, and is a surface perpendicular to the paper surface. The hemming device is disposed behind the workpiece 10, the first hemming mechanism 100 and the second hemming mechanism 200 are disposed opposite to each other in the vertical direction, and the third hemming mechanism 300 is disposed between the first hemming mechanism 100 and the second hemming mechanism 200.

Specifically, when the first end portion 21 is folded, the first edge folding mechanism 100 folds the adhesive tape toward the fourth surface 14 from top to bottom; when the second end portion 22 is folded, the second edge folding mechanism 200 folds the adhesive tape from bottom to top toward the fourth surface 14; when the middle portion 23 is folded, the third folding mechanism 300 folds the tape from right to left toward the fourth surface 14.

The first folding mechanism 100 includes a first folding member 110 and a first folding driving assembly 120, and the first folding driving assembly 120 is connected to the first folding member 110 and can drive the first folding member 110 to move from the first side 11 of the workpiece 10 toward the fourth side 14.

When the tape is folded, the first folding member 110 presses the tape against the fourth surface 14, and finally presses the tape against the fourth surface 14. It is easy to understand that when the adhesive tape protruding from the fourth surface 14 is long, the first folding member 110 abuts against the fourth surface 14 once, and the entire first end portion 21 cannot be attached to the fourth surface 14; for this, the first folder 110 may employ a pressing roller; after the roller surface abuts against the fourth surface 14, the first folding driving assembly 120 can drive the roller to flatten the adhesive tape along the fourth surface 14 and toward the second surface 12, so that the adhesive tape is completely adhered to the fourth surface 14. Through setting up first hem piece 110 as the compression roller, when first hem piece 110 moved along fourth 14, the roller of compression roller can be around self axis rotation, and then makes things convenient for first hem piece 110 to move.

The first folding driving assembly 120 includes a first folding guide 121 and a first folding driving member 122; the first hemming guide 121 extends from the first side 11 to the second side 12; the first folding member 110 is slidably disposed on the first folding guide 121, and the first folding driving member 122 is connected to the first folding member 110 and can drive the first folding member 110 to move along the fourth surface 14.

The first hemming guide 121 may be a guide member such as a guide bar or a guide rail; the first folding driving member 122 may be a pneumatic cylinder, an electric cylinder, or the like.

In a specific embodiment, referring to fig. 4 and 5, the first hemming guide 121 is disposed in a vertical direction. At this time, after the workpiece 10 to be hemmed is in place, the fourth side 14 from which the adhesive tape protrudes faces the hemming device, and the first hemming member 110 is suspended above the first side 11. When the first end portion 21 is folded, the first folding driving member 122 drives the first folding member 110 to move downward, so that the first folding member 110 is close to the first face 11; after the adhesive tape pressed to the first end portion 21, the first folding member 110 continues to move downward, and drives the adhesive tape to fold toward the fourth surface 14; the first flap 110 abuts the fourth surface 14, thereby smoothing the tape over the fourth surface 14.

It is easy to understand that when the first folding member 110 moves from the first surface 11 toward the fourth surface 14, it is difficult to ensure that the first folding member 110 abuts against the fourth surface 14, and therefore, the first folding mechanism 100 further includes the first elastic element 130.

The first elastic member 130 includes: a first mounting plate 131 connected to the first hemming drive assembly 120; a first swing arm 132 swingably provided on the first mounting plate 131; a first fixing plate 133 fixedly disposed on the first mounting plate 131; a first elastic member 134 having one end abutting against the first fixing plate 133 and the other end abutting against one end of the first swing arm 132; wherein, the first folding member 110 is arranged at the other end of the first swing arm 132; when the first folding member 110 continuously presses against the fourth surface 14, the fourth surface 14 applies a reverse acting force to the first folding member 110, the first folding member 110 drives the other end of the first swing arm 132 to swing towards a direction away from the fourth surface 14, and further drives one end of the first swing arm 132 to swing towards the first fixing plate 133, so as to compress the first elastic member 134.

By utilizing the characteristic of relative swinging of the two ends of the first swing arm 132, when the first folding member 110 continuously abuts against the fourth surface 14, the configuration and the position of the fourth surface 14 push the first folding member 110 to match with the fourth surface; at this time, the first swing arm 132 drives the first elastic member 134 to compress and deform to adapt to the position change of the first folding member 110. Meanwhile, the first folding member 110 can always abut against the fourth surface 14 by the elastic recovery of the first elastic member 134 and the reaction force applied to the first swing arm 132.

Wherein, the first elastic member 134 may be a spring.

In a specific embodiment, referring to fig. 5, the first folding member 110 is a pressing roller, and in order to better drive the pressing roller to act, two sets of first swing arms 132 are provided, and two sides of the pressing roller shaft are respectively connected with one set of first swing arms 132; two sets of first swing arms 132 are rotatably connected to both sides of the first mounting plate 131 through rotating shafts. In order to ensure the stress balance of the two ends of the press roll, a group of first fixing plates 133 are respectively arranged at the positions, opposite to one ends of the two groups of first swing arms 132, of the two sides of the first mounting plate 131; meanwhile, a first elastic member 134 is disposed between the two sets of corresponding first fixing plates 133 and first swing arms 132. In this way, after the workpiece 10 to be flanged is in place, the first flanging driving element 122 drives the first flanging element 110 to move downwards, so that the first flanging element 110 is close to the first surface 11; after the first folding member 110 presses the protruding first end portion 21, the adhesive tape is driven to continue to be folded downwards, so that the adhesive tape is folded towards the fourth surface 14. To ensure that the first folding member 110 abuts the fourth face 14, the initial position of the first folding member 110, there is a projection on the first face 11; that is, when the first folding driving member 122 drives the first folding member 110 to move downward, a portion of the first folding member 110 abuts against the first surface 11, but as the first folding driving member 122 continues to drive the first folding member 110 to move downward, the first folding member 110 gradually attaches to the fourth surface 14; at this time, the first folding member 110 moves to the right from the adjacent edge of the first surface 11 and the fourth surface 14, the first folding member 110 drives one end of the first swing arm 132 to swing to the right, and the other end of the first swing arm 132 moves to the left, compressing the first elastic member 134; after the first folding member 110 is separated from the first surface 11 and attached to the fourth surface 14, the first folding member 110 is adjusted to fit the fourth surface 14, the first elastic member 134 elastically returns, and the reaction force thereof enables the first folding member 110 to always abut against the adhesive tape on the fourth surface 14.

The second hemming mechanism 200 is similar to the first hemming mechanism 100 in structure, and includes a second hemming member 210 and a second hemming driving assembly 220, wherein the second hemming driving assembly 220 is connected to the second hemming member 210 and is capable of driving the second hemming member 210 to move from the second side 12 of the workpiece 10 toward the fourth side 14. Details are not repeated.

The second hemming mechanism 200 is different from the first hemming mechanism 100 in that the first hemming driving assembly 120 drives the first hemming device 110 to move along the direction of the first surface 11 toward the second surface 12 while the second hemming driving assembly 220 drives the second hemming device 210 to move along the direction of the second surface 12 toward the first surface 11 when folding the corresponding adhesive tapes.

Further, the second folding mechanism 200 further includes a second elastic element 230, which is similar to the second folding element 210 and the second folding driving element 220 in the way of matching the first elastic element 130 with the first folding element 110 and the first folding driving element 120, and will not be described herein again.

The third hemming mechanism 300 includes: the third edge part 310 and the third edge driving component 320, wherein the third edge driving component 320 is connected to the third edge part 310 and can drive the third edge part 310 to move from the third surface 13 to the fourth surface 14 of the workpiece 10.

The third folding edge 310 may be a pressing roller, and the axial direction of the pressing roller extends along the direction from the first surface 11 to the second surface 12; therefore, when the third edge folding driving assembly 320 drives the pressing roller to move, the pressing roller can gradually fold and adhere the adhesive tape extending from the third surface 13 to the fourth surface 14.

In one embodiment, referring to fig. 4, since the distance between the first side 11 and the second side 12 is not large, so that the fourth side 14 is narrow, if the third folding edge 310 is provided as a compression roller, the configuration of the compression roller can be rearranged as required, thereby increasing the design cost. Thus, the third flange 310 is directly a plate member, and the width of the plate member is not narrower than the fourth surface 14. At this point, after the workpiece 10 is in place, the third edge piece 310 is outside the third face 13, i.e., outside the vertical plane of the drawing; the third edge folding driving assembly 320 drives the third edge folding member 310 to move from outside to inside towards the third surface 13, and after the third edge folding member 310 presses the adhesive tape on the middle portion 23, the adhesive tape is driven to continue to move inwards, so that the adhesive tape is folded towards the fourth surface 14; the third edge member 310 abuts against the adhesive tape on the fourth surface 14, and as the third edge member 310 continuously moves inward, the adhesive tape is gradually smoothed out, so that the adhesive tape is completely adhered to the fourth surface 14.

The third folding edge driving assembly 320 includes a third folding edge guide 321 and a third folding edge driving member 322; the third hem guide 321 is provided extending in the width direction of the first face 11 or the second face 12; the third edge 310 is slidably disposed on the third edge guide 321, and the third edge driving member 322 is connected to the third edge 310 and can drive the third edge 310 to move along the fourth surface 14.

The third folding edge guide 321 may adopt guide members such as a guide rod and a guide rail; the third edge-folding driving member 322 can adopt a driving member such as an air cylinder, an electric cylinder, etc.

As can be easily understood, when the third edge 310 moves from the third surface 13 toward the fourth surface 14, it is difficult to ensure that the third edge 310 abuts against the fourth surface 14, and thus the third edge folding mechanism 300 further includes a third elastic component 330; the third elastic member 330 includes: a third mounting plate 331 connected to the third edge folding driving assembly 320; a third elastic guide 332 disposed on the third mounting plate 331, the third folding edge 310 being slidably disposed on the third elastic guide 332; a third elastic member 333 having one end abutting against the third mounting plate 331 and the other end abutting against the third flange member 310; when the third edge part 310 continuously abuts against the fourth surface 14, the fourth surface 14 exerts an opposite force on the third edge part 310, so that the third edge part 310 moves along the third elastic guide 332 in a direction away from the fourth surface 14, thereby compressing the third elastic part 333.

In one embodiment, referring to fig. 6, the third elastic guide 332 is disposed in a vertical direction, and the third folding edge 310 is slidably disposed on the third elastic guide 332. When the workpiece 10 is in place, the third edge piece 310 has a projection on the third face 13; that is, when the third edge driving assembly 320 drives the third edge 310 to move from right to left, a portion of the third edge 310 abuts against the third surface 13; as the third edge driving assembly 320 continues to drive the third edge 310 to move to the left, the adjoining edges of the third and fourth faces 13 and 14 push the third edge 310 upward, so that the third edge 310 moves upward along the third elastic guide 332, compressing the third elastic member 333; after the third edge part 310 is completely separated from the third surface 13, the elastic restoring force of the third elastic part 333 acts on the third edge part 310 in a reverse direction, so that the third edge part 310 always abuts against the fourth surface 14, and the third edge part 310 smooths the adhesive tape on the fourth surface 14.

The third elastic guide 332 may adopt guide members such as a guide rod and a guide rail; the third elastic member 333 may employ a spring.

Further, the end of the third edge 310 contacting the tape is set to be arc-shaped.

It will be readily appreciated that when a plate member is used as the third edge member 310, if the end of the plate member contacting the tape is square, on the one hand, the tip end thereof tends to abrade the tape or the fourth surface 14 of the workpiece 10; on the other hand, when the third folding edge 310 is projected on the third surface 13, it is difficult to easily move the end of the third folding edge into the fourth surface 14 after contacting the third surface 13. At this time, the end of the third edge 310 contacting the tape is set to be arc-shaped, so that the outer side of the end of the third edge 310 contacting the tape is contracted inwards to facilitate entering the fourth surface 14 from the third surface 13 along the plate; meanwhile, the arc-shaped end portion is less likely to damage the adhesive tape or the surface of the workpiece 10 in contact therewith.

It should be added that, for the adhesive tapes protruding from the first end portion 21, the second end portion 22 and the middle portion 23 of the fourth surface 14, when folding, the first folding mechanism 100 may fold the first end portion 21 of the adhesive tape first, then the second folding mechanism 200 folds the second end portion 22 of the adhesive tape, and finally the third folding mechanism 300 folds the third end portion 23 of the adhesive tape. The operation sequence of the first hemming mechanism 100, the second hemming mechanism 200, and the third hemming mechanism 300 may not be limited in the present application, as the second hemming mechanism 200 folds the first end portion 21 of the adhesive tape first, then the first hemming mechanism 100 folds the second end portion 22 of the adhesive tape, and finally the third hemming mechanism 300 folds the third end portion 23 of the adhesive tape onto the fourth surface 14 … ….

It should be added that, if the portion of the adhesive tape protruding from the fourth surface 14 is narrow, after the first end portion 21 and the second end portion 22 are folded over the fourth surface 14, the two portions may be directly attached to the fourth surface 14 without contacting each other, but the intermediate portion 23 adjacent to the first end portion 21 and the second end portion 22 may contact the adhesive tape of the first end portion 21 and the second end portion 22. If the part of the adhesive tape protruding from the fourth surface 14 is wider, after the first end portion 21 and the second end portion 22 are folded over the fourth surface 14, the two parts may overlap each other, the folded part is adhered to the fourth surface 14, and then the folded part is adhered to the non-adhesive surface of the adhesive tape; in any case, since the tape surface of the tape is folded toward the fourth surface 14, the tape can be finally applied.

Further, the hemming device provided by the present application further includes a glue pressing mechanism 400, and the glue pressing mechanism 400 is disposed opposite to the fourth surface 14; after the first edge folding mechanism 100 folds the first end portion 21 on the fourth surface 14, the second edge folding mechanism 200 folds the second end portion 22 on the fourth surface 14, and the third edge folding mechanism 300 folds the middle portion 23 on the fourth surface 14, the adhesive pressing mechanism 400 moves toward the fourth surface 14 to press the adhesive tape folded on the fourth surface 14.

It will be readily appreciated that the adhesive tape folded over fourth surface 14 does not ensure that the adhesive side is fully adhered to fourth surface 14. Therefore, the glue pressing mechanism 400 is arranged, after the adhesive tape protruding out of the fourth surface 14 is turned over, the glue pressing mechanism 400 directly moves towards the fourth surface 14, and the turned adhesive tape is compacted.

Specifically, the caulking mechanism 400 includes: the pressing member 410 and the pressing driving assembly 420, wherein the pressing driving assembly 420 is connected to the pressing member 410 and can drive the pressing member 410 to move toward the fourth surface 14.

The glue pressing piece 410 can be a pressing plate, and the plate surface of the pressing plate is larger than the fourth surface 14; the glue pressing driving assembly 420 can adopt driving components such as an air cylinder, an electric cylinder and the like; in this manner, the pressing driving assembly 420 can directly drive the pressing member 410 against the fourth surface 14 and compact the entire fourth surface 14.

When the pressing member 410 presses against the fourth surface 14, in order to ensure the pressing of the adhesive tape, the driving stroke of the pressing driving assembly 420 is greater than the distance between the pressing member 410 and the fourth surface 14 in the initial state, so that the pressing member 410 tightly presses the fourth surface 14; that is, after the pressing member 410 contacts the fourth surface 14, the pressing driving assembly 420 continues to drive the pressing member 410 to move against the fourth surface 14. However, in this case, as the fourth surface 14 is continuously pressed by the caulking member 410, the workpiece 10 is easily pushed, so that the workpiece 10 is pushed away. Therefore, when the pressing member 410 is a pressing plate, a flexible block is further disposed on a surface of the pressing plate abutting against the fourth surface 14; the flexible block can be made of flexible materials such as silica gel and polyurethane. The flexible block has a certain deformation amount, so that when the glue pressing piece 410 presses against the fourth surface 14, the flexible block can be compressed to compensate for the redundant driving stroke of the glue pressing driving assembly 420; meanwhile, the elastic restoring force of the flexible member acts on the fourth surface 14 in an opposite direction, so that the adhesive pressing member 410 can abut against the fourth surface 14.

In actual practice, in one embodiment, the workpiece 10 may be directly conveyed to a position where the hemming device can be operated by a conveying device (not shown), and the first hemming mechanism 100, the second hemming mechanism 200, and the third hemming mechanism 300 may directly process the workpiece 10.

In another embodiment, the hemming device further comprises a translation drive mechanism 500; the translation driving mechanism 500 is connected with the first hemming mechanism 100, the second hemming mechanism 200, and the third hemming mechanism 300, and can drive them to approach or move away from the hemming station. The folding station is a fixed station after the workpiece 10 to be folded enters the folding device, the conveying equipment directly conveys the workpiece 10 to the folding station, and then the translation driving mechanism 500 drives the first folding mechanism 100, the second folding mechanism 200 and the third folding mechanism 300 to be close to the station to realize folding; after the edge folding is finished, the translation driving mechanism 500 drives the first edge folding mechanism 100, the second edge folding mechanism 200 and the third edge folding mechanism 300 to be away from the station, so that the conveying mechanism can conveniently take away the folded workpiece 10 and then carry in a new workpiece 10 to be folded.

The translation driving mechanism 500 may adopt driving members such as an electric cylinder, a motor screw, a module, and the like.

The application also discloses a flanging device, which comprises two groups of flanging devices; when the adhesive tape covers the workpiece 10, two side edges of the adhesive tape respectively protrude out of the fourth surface 14 and the fifth surface 15; the fourth surface 14 and the fifth surface 15 are adjacent to the first surface 11, the second surface 12 and the third surface 13, and the fourth surface 14 and the fifth surface 15 are oppositely arranged; a set of folding means is provided opposite the fourth face 14 for folding the protruding adhesive tape onto the fourth face 14; another set of folding means is provided opposite the fifth face 15 for folding the protruding tape onto the fifth face 15.

As mentioned above, the adhesive tape may protrude from the workpiece 10 on both sides in the width direction, and the protruding adhesive tape needs to be folded back onto the corresponding fourth surface 14 or fifth surface 15.

In one embodiment, referring to fig. 7, a first surface 11 of a workpiece 10 is an upper surface of the workpiece 10, a second surface 12 is a lower surface of the workpiece 10, a third surface 13 is an inner surface of the workpiece 10 that is hidden from view, a fourth surface 14 is a right surface of the workpiece 10, and a fifth surface 15 is a left surface of the workpiece 10. At this time, the two sets of hemming devices are oppositely arranged along the left and right direction. The workpiece 10 to be hemmed is moved into between the two sets of hemming devices, and the fourth surface 14 and the fifth surface 15 of the workpiece face to the two sets of hemming devices respectively, so that the two sets of hemming devices can conveniently hem the adhesive tapes protruding out of the two surfaces respectively, and the hemming efficiency is further improved.
