[0064] Figure 1-Figure 8 Schematic diagram of the structure of the cutting device of this embodiment. Figure 1 As shown, the pasting and cutting device includes a fixed frame 1, a fixed wheel 2, a glue pasting mechanism 3, a power mechanism 4 and a cutting mechanism 5. The fixed wheel 2 is rotatably arranged on the fixed frame 1 through a rotating shaft and is located on the side of the power mechanism 4 facing away from the glue pasting mechanism 3. Figure 1 The fixed wheel 2 is used to fix the tape material wheel C, so that the tape material wheel C can rotate with the fixed wheel 2, as shown. Figure 1 In this embodiment, the tape material wheel C refers to a roll-shaped structure formed by winding a tape, and the pasting and cutting device is used to press the tape on the tape material wheel C onto the pasted workpiece B. In other optional embodiments, the tape material wheel C can also be a roll-shaped structure formed by winding a tape or wire of any material, which can be selected according to the actual application.

[0065] The power mechanism 4 is arranged on the fixing frame 1 in a relatively rotatable manner, and the power mechanism 4 is transmission-connected with the glue sticking mechanism 3. Figure 1 The power mechanism 4 is used to drive the glue sticking mechanism 3 to move and thus realize the glue sticking action.

[0066] Specifically, the power mechanism 4 includes a transmission wheel 41, a connecting arm 43 and a gravity wheel 42. Figure 7 and Figure 8 The transmission wheel 41 is rotatably connected to the fixing frame 1 and is transmission-connected to the glue sticking mechanism 3. Figure 1 When the transmission wheel 41 is controlled to rotate, it can drive the glue sticking mechanism 3 to move and thus realize the glue sticking action.

[0067] The transmission wheel 41 includes a connecting portion 411 and a fan-shaped transmission portion 412. The fan-shaped transmission portion 412 is arranged radially outside the connecting portion 411. Figure 7 As shown. Wherein, the connecting portion 411 is a cylindrical structure, which is rotatably connected to the fixed frame 1 through a rotating shaft. The fan-shaped transmission portion 412 is fixedly connected to the connecting portion 411 in a concentric manner, and the connecting portion 411 can drive the fan-shaped transmission portion 412 to rotate together. The outer side of the fan-shaped transmission portion 412 has meshing teeth, which drives the glue-applying mechanism 3 to move when the fan-shaped transmission portion 412 rotates. In this embodiment, the connecting portion 411 and the fan-shaped transmission portion 412 can be formed in one piece, which can ensure that the connecting portion 411 and the fan-shaped transmission portion 412 are concentric, thereby improving the transmission efficiency of the transmission wheel 41. In other embodiments, the connecting portion 411 and the fan-shaped transmission portion 412 can also be connected by welding, bolts, buckles, etc.

[0068] The gravity wheel 42 is connected to the outer side of the connecting portion 411 through the connecting arm 43, and the gravity wheel 42 extends downward to the outer side of the fixing frame 1. Figure 1 When the bottom of the gravity wheel 42 is lifted or the gravity wheel 42 and the connecting arm 43 fall due to their own weight, the gravity wheel 42 drives the transmission wheel 41 to rotate through the connecting arm 43 and transmits the transmission to the glue sticking mechanism 3, so that the glue sticking mechanism 3 slides up and down.

[0069] One end of the connecting arm 43 is fixedly connected to the radial outer side of the connecting portion 411 of the transmission wheel 41, and the other end of the connecting arm 43 is relatively rotatably connected to the gravity wheel 42 via a rotating shaft. The gravity wheel 42 can rotate during the lifting process, thereby reducing the friction force on the gravity wheel 42 and increasing the service life of the gravity wheel 42.

[0070] In other embodiments, the connecting arm 43 includes a first portion 431 and a second portion 432. The first portion 431 is fixedly connected to the connecting portion 411 and extends radially outward along the connecting portion 411. The first portion 431 is provided with a groove having an opening on one side. One end of the second portion 432 is rotatably connected to the gravity wheel 42, and the other end is inserted into the groove of the first portion 431 and fixedly connected by a fastener. The arrangement of the connecting arm 43 facilitates the assembly and connection of the gravity wheel 42 and the transmission wheel 41. Preferably, when the distance between the transmission wheel 41 and the gravity wheel 42 needs to be adjusted according to actual conditions, a second portion 432 of a suitable length can also be selected to connect the transmission wheel 41 and the gravity wheel 42.

[0071] In this embodiment, the angle between the first portion 431 and the fan-shaped transmission portion 412 can be any angle between 0 and 180 degrees according to specific settings. Preferably, the angle is less than 90 degrees.

[0072] The power mechanism 4 further includes a transition gear 44, which is rotatably disposed on the fixing frame 1. Figure 1 As shown. Among them, the transition gear 44 is located between the fan-shaped transmission part 412 and the spur rack 3b of the gluing mechanism 3, and is meshed and connected with the spur rack 3b and the fan-shaped transmission part 412 respectively. The transmission wheel 41 drives the gluing mechanism 3 to move through the transition gear 44, so as to ensure that the transmission wheel 41 can transmit the transmission force to the gluing mechanism 3 and drive the gluing mechanism 3 to move. At the same time, when the transmission wheel 41 transmits the transmission force to the gluing mechanism 3 through the transition gear 44, it can be ensured that when the gravity wheel 42 is lifted upward, the transition gear 44 drives the gluing mechanism to move downward in the opposite direction to press the tape A onto the workpiece to be pasted. When the gravity wheel 42 moves downward due to its own weight, the transition gear 44 drives the gluing mechanism to move upward to complete the gluing.

[0073] The glue sticking mechanism 3 includes a connecting plate 31, a first sliding assembly 32, a glue holding plate 33, a pressing wheel 34, a pressing wheel carrier plate 35, a stopper 36, an elastic member 37 and a limit block 39. Figure 2 As shown. Among them, the connecting plate 31 is connected to the fixed frame 1 for sliding up and down movement through the first sliding component 32. The connecting plate 31 is provided with a spur rack 3b on the side facing the transition gear 44, and the transition gear 44 is respectively meshed and connected with the spur rack 3b and the fan-shaped transmission part 412, thereby driving the connecting plate 31 to move up and down. In this embodiment, the first sliding component 32 includes a slide rail and a slider that cooperate with each other. The slide rail is fixed on the fixed frame 1, and the slider is fixed on the connecting plate 31. In order to avoid the slider from interfering with the cutting mechanism 5 when moving on the slide rail, the slider is arranged at a position near the top of the connecting plate 31.

[0074] The rubber holding plate 33 is fixedly connected to the bottom of the connecting plate 31, and the rubber holding plate 33 extends downward to the outside of the bottom of the connecting plate 31. The rubber holding plate 33 includes a guide groove 3a, and the opening of the guide groove 3a faces the tape material wheel C, so that the tape A on the tape material wheel C can extend through the guide groove 3a of the rubber holding plate 33.

[0075] In a preferred embodiment, an angle is formed between the bottom of the guide groove 3a and the surface of the workpiece B to be pasted, so as to prevent the tape A from being worn against the edge of the guide groove 3a when entering the guide groove 3a. The width of the guide groove 3a is adapted to the width of the tape A, so as to prevent the tape A from curling due to a too small width or from shaking due to a too large width, which affects the quality of pasting.

[0076] The rubber holding plate 33 includes a bottom plate 331 and two side walls 332. Figure 6 As shown. The bottom plate 331 includes a first top surface 333 and a second top surface 334, which form a step, and the second top surface 334 is located on a side close to the pressure wheel 34 relative to the first top surface 333. Two side walls 332 are relatively arranged on both sides of the first top surface 333, and form the guide groove 3a with the first top surface 333. The adhesive tape A passes over the first top surface 333 and the second top surface 334 of the adhesive holding plate 33 in sequence. The step formed by the first top surface 333 and the second top surface 334 can reduce the contact area with the adhesive tape A and reduce the adhesive force of the adhesive tape A. In this embodiment, the material of the adhesive holding plate 33 is a non-stick material, such as Teflon.

[0077] The pressure wheel carrier plate 35 is connected to the connecting plate 31 by sliding up and down through the second sliding assembly 38. Figure 2As shown. One side of the pressure wheel carrier plate 35 extends downward and extends from below the connecting plate 31. In this embodiment, the second sliding assembly 38 includes a slide rail and a slider that cooperate with each other. The slide rail is fixed on the connecting plate 31, and the slider is fixed on the connecting plate 31.

[0078] The pressing wheel 34 is rotatably connected to the pressing wheel carrier 35, and the bottom of the pressing wheel 34 extends from the bottom of the pressing wheel carrier 35. The pressing wheel 34 is used to press the adhesive tape A onto the workpiece B to be pasted. The pressing wheel 34 is located on the side of the adhesive holding plate 33 facing away from the fixed wheel 2, and the pressing wheel 34 is close to the second top surface 334 of the adhesive holding plate 33. The adhesive tape A extends through the guide groove 3a of the adhesive holding plate 33 and extends to the bottom of the pressing wheel 34, so that the pressing wheel 34 can press the adhesive tape A onto the workpiece B to be pasted. Preferably, the bottom of the pressing wheel 34 is lower than the bottom of the adhesive holding plate 33.

[0079] In a preferred embodiment, the outer circumference of the pressing wheel 34 has a certain degree of flexibility to prevent the tape A from being scratched when the tape A is pressed against the workpiece B. For example, a layer of flexible material such as silicone or rubber may be provided on the outer circumference of the pressing wheel 34 .

[0080] Furthermore, a stopper 351 is formed on one side of the pressure wheel carrier plate 35 extending outward. The limit block 39 is fixedly connected to the connecting plate 31 and extends to the bottom of the stopper 351 and is arranged vertically opposite to the stopper 351. The stopper 36 is fixedly connected to the connecting plate 31, and the stopper 36 is located above the pressure wheel carrier plate 35 and the second sliding assembly 38. The stopper 36 and the stopper 351 are used to limit the range of the pressure wheel carrier plate 35 moving up and down. The stopper 351 can be located on the side of the pressure wheel carrier plate 35 facing away from the rubber holding plate 33 or on the side close to the rubber holding plate 33, and the corresponding stopper 351 is located on the same side as the stopper 351.

[0081] The elastic member 37 elastically abuts between the stopper 36 and the pressure wheel carrier plate 35, so that the pressure wheel 34 increases the flexibility of the pressure wheel 34 during the gluing process. Since the pressure wheel 34 needs to be pressed on the workpiece B to be glued during the gluing process, and the surface flatness of the workpiece B to be glued is uncertain and the heights of different workpieces B to be glued are different, the pressure wheel 34 can be adjusted to adapt to the height of the workpiece B to be glued through the elastic member 37.

[0082] In a preferred embodiment, the fixed wheel 2, the glue holding plate 33 and the pressure wheel 34 extend to the outside of the power mechanism 3 in a lateral direction perpendicular to the connecting plate 31, and the fixed wheel 2, the glue holding plate 33 and the pressure wheel 34 are located in the same plane, so that a section of the tape A extending from the tape material wheel C to the glue holding plate 33 is located on the outside of the power mechanism 3, which can prevent the tape A from interfering with the power mechanism 3 during the glue sticking process and affecting the glue sticking.

[0083] In this embodiment, when the gravity wheel 42 is not subjected to external force, the bottom of the gravity wheel 42 is located below the bottom of the rubber holding plate 33 , and a preset distance is formed between the gravity wheel 42 and the bottom of the rubber holding plate 33 .

[0084] When the bottom of the gravity wheel 42 is lifted by the workpiece B to be pasted to be flush with the adhesive holding plate 33, the gravity wheel 42 drives the transmission wheel 41 to rotate through the connecting arm 43 and indirectly transmits the transmission to the connecting plate 31 through the transition gear 44, so that the connecting plate 31 can drive the adhesive holding plate 33 and the pressure wheel 34 to move downward, and drive the cutting mechanism 5 to separate from the adhesive workpiece B, until the bottom of the pressure wheel 34 is flush with the bottom of the gravity wheel 42 and presses on the adhesive workpiece B at the same time, and the transmission wheel 41 stops rotating. At this time, the bottom of the adhesive holding plate 33 is slightly higher than the gravity wheel 42 and the pressure wheel 34, which can prevent the adhesive holding plate 33 from scratching and damaging the tape A. In this state, the pressure wheel 34 presses the tape A, controls the lateral movement of the pasting and cutting equipment or the pasted workpiece B, and can press the tape A on the pasted workpiece B to complete the pasting work.

[0085] When the workpiece B to be pasted leaves from the bottom of the pasting and cutting equipment, the gravity wheel 42 and the connecting arm 43 fall to the preset distance due to their own weight, and the connecting arm 43 drives the transmission wheel 41 to rotate in the opposite direction and transmits the transmission to the connecting plate 31, so that the connecting plate 31 can drive the glue holding plate 33 and the pressure wheel 34 to move upward, and drive the cutting mechanism 5 to swing in the direction close to the workpiece B to cut the tape A and complete the glue cutting action.

[0086] In this embodiment, the pasting and cutting device further comprises a reset member 6, one end of which is fixedly connected to the fixing frame 1, and the other end of which is fixedly connected to the connecting plate 31. Figure 2 As shown. Preferably, one end of the reset member 6 connected to the fixing frame 1 is located above one end of the reset member 6 connected to the connecting plate 31. When the connecting plate 31 slides downward, the reset member 6 is driven to deform and store energy. When the connecting plate 31 moves upward, the reset member 6 can provide a certain amount of power to the connecting plate 31, and at the same time can eliminate the gap between the gears, increase the accuracy of the mechanism and reduce the noise during the operation of the mechanism. The elastic member 37 and the reset member 6 can be springs, or they can be structures made of elastic materials such as memory alloys and silicone.

[0087] The cutting mechanism 5 includes a swing arm 51, a connecting shaft 52, a clamping portion 53 and a cutting knife 54. Figure 1 , Figure 4 and Figure 5 The swing arm 51 is located between the fixing frame 1 and the connecting plate 31 , the swing arm 51 is rotationally connected to the fixing frame 1 , and the swing arm 51 is transmission-connected to the connecting plate 31 .

[0088] In this embodiment, the swing arm 51 has a moving groove 511, and the moving groove 511 is a long strip through hole. One end of the connecting shaft 52 is fixedly connected to the connecting plate 31, and the other end of the connecting shaft 52 is inserted into the moving groove 511. The clamping portion 53 is fixedly connected to the outer end of the swing arm 51, and the cutter 54 is fixedly connected to the clamping portion 53. The clamping portion 53 and the moving groove 511 are located on both sides of the rotation center of the swing arm 51. When the connecting plate 31 moves up and down, the connecting shaft 52 drives the swing arm 51 to rotate around the rotation center by moving in the moving groove 511, thereby driving the clamping portion 53 and the cutter 54 to swing.

[0089] In this embodiment, the rotation center of the swing arm 51 is located below the slide rail of the first sliding assembly 32, and the movable groove 511 is located on the side of the rotation center of the swing arm 51. The length of the swing arm 51 is smaller than the distance from the rotation center to the bottom of the slide rail, which can prevent the swing arm 51 from interfering with the slide rail of the first sliding assembly 32 during the swinging process and affecting the cutting mechanism 5 to cut the rubber.

[0090] The clamping portion 53 is fixedly connected to the outer end of the swing arm 51 and extends outward to be located in the same plane as the pressure wheel 34 and the rubber holding plate 33. In a preferred embodiment, the clamping portion 53 has a mounting through hole 531 and a fastening hole 532. Figure 4 As shown. The width and thickness of the mounting through hole 531 are adapted to the width and thickness of the cutter 54, so that the cutter 54 can be installed in the mounting through hole 531. The connection direction of the mounting through hole 531 is perpendicular to the connection direction of the fastening hole 532, and a gap is provided on one side of the mounting through hole 531. When the fastener 55 fixes the cutter 54, the gap can provide a certain movement space for the deformation of the mounting through hole 531, thereby fastening the cutter 54.

[0091] The cutter 54 has an adjustment hole 541. Figure 4As shown. When the cutter 54 is arranged in the mounting through hole 531, the thickness direction of the adjustment hole 541 and the mounting through hole 531 is the same, and they are connected with the fastening hole 532. The fastener 55 passes through the fastening hole 532 and the adjustment hole 541 to fix the cutter 54 with the clamping portion 53. In this embodiment, the adjustment hole 541 is a long strip-shaped through hole. When it is necessary to adjust the length of the cutter 54 extending from the clamping portion 53, different positions of the adjustment hole 541 can be connected with the fastening hole 532 and fixed by the fastener 55.

[0092] In this embodiment, the head of the cutter 54 faces the adhesive tape A below the pressing wheel 34, and is used to cut the adhesive tape A. Specifically, the head of the cutter 54 refers to the portion extending from the side of the clamping portion 53 close to the pressing wheel 34. The head of the cutter 54 forms an angle with the fixed position of the cutter 54, and the angle makes the head of the cutter 54 tilt downward and point to the adhesive tape A below the pressing wheel 34. The head of the cutter 54 is a V-shaped structure, which is convenient for cutting the adhesive tape A.

[0093] When the connecting plate 31 slides upward, the connecting shaft 52 drives the swing arm 51, the clamping portion 53 and the cutter 54 to swing downward through the moving groove 511, so that the cutter 54 cuts the adhesive tape A below the pressing wheel 34. When the connecting plate 31 slides downward, the connecting shaft 52 drives the swing arm 51, the clamping portion 53 and the cutter 54 to swing upward through the moving groove 511, so that the cutter 54 is separated from the pressing wheel 34.

[0094] Furthermore, the cutting device further comprises a tension wheel 7, and the tension wheel 7 is rotatably connected to the fixing frame 1. Figure 1 As shown. The tensioning wheel 7 is located between the fixed wheel 2 and the adhesive holding plate 33, and the tensioning wheel 7 is used to tension the tape A between the tape material wheel C and the adhesive holding plate 33, so as to avoid that the tape A cannot effectively pass through the adhesive holding plate 33 under the action of gravity due to the long distance between the tape material wheel C and the adhesive holding plate 33 during the adhesive application process. In this embodiment, in order to avoid that the adhesive surface of the tape A is damaged during the contact between the tensioning wheel 7 and the tape A, the tape A passes under the tensioning wheel 7. In this embodiment, the tensioning wheel 7 is located between the tape material wheel C and the transmission wheel 41. The number of the tensioning wheels 7 can be set according to specific needs, and the number is not limited to one or two.

[0095] In a preferred embodiment, the fixed wheel 2 is located above the rubber holding plate 33, and the distance between the fixed wheel 2 and the rubber holding plate 33 can be adjusted. Specifically, the cutting device further includes an adjustment plate, the fixed wheel 2 can be rotatably connected to one end of the adjustment plate, and the other end of the adjustment plate can be provided with a length adjustment hole, which is fixedly connected to different positions of the adjustment plate through fasteners, thereby realizing the position adjustment of the fixed wheel 2.

[0096] In this embodiment, the workpiece B to be glued is placed on a carrier. When the glue-sticking and glue-cutting equipment is performing glue-sticking and glue-cutting, the glue-sticking can be performed in two moving modes. The first moving mode: the carrier drives the workpiece B to be glued to move horizontally, and the glue-sticking and glue-cutting equipment is fixed; the second moving mode: the glue-sticking and glue-cutting equipment moves horizontally, and the carrier and the workpiece B to be glued are fixed.

[0097] For the first moving mode, the gluing and cutting process of the gluing and cutting equipment includes:

[0098] (1) When the carrier drives the workpiece B to move to the bottom of the pasting and cutting equipment, the carrier lifts the gravity wheel 42, drives the transmission wheel 41 to rotate counterclockwise and the transition gear 44 to rotate clockwise through the connecting arm 43, and indirectly drives the gluing mechanism 3 to move downward, so that the pressure wheel 34 presses down on the surface of the carrier or the workpiece B to be pasted, and drives the cutting knife mechanism 5 to swing upward counterclockwise, and the cutting knife 54 is lifted; then the carrier pressure wheel 34 continues to move to press the tape A on the top of the workpiece B to be pasted to perform the gluing operation. In this process, the gravity wheel 42 and the pressure wheel 34 are pressed on the surface of the workpiece B to be pasted and roll at the same time, which can reduce the friction between the workpiece B to be pasted and avoid excessive wear of the workpiece B and the gravity wheel 42.

[0099] (2) When the carrier drives the workpiece B to be pasted through the pasting and cutting equipment, the gravity wheel 42 drops due to its own weight, and drives the transmission wheel 41 to rotate clockwise and the transition gear 44 to rotate counterclockwise through the connecting arm 43, thereby indirectly driving the gluing mechanism 3 to move upward, so that the pressure wheel 34 is separated from the carrier, and drives the cutting knife mechanism 5 to swing clockwise downward, and the cutting knife 54 cuts the tape A to complete the glue cutting operation.

[0100] For the second moving mode, the adhesive bonding and cutting equipment is controlled to move horizontally, and the carrier and the adhesive workpiece B are fixed, so that relative movement is achieved between the two. The adhesive bonding and cutting actions achieved by the second moving mode are the same as those achieved by the first moving mode, and will not be repeated here.

[0101] The pasting and cutting equipment of this embodiment increases the linkage between the mechanisms and reduces the actuators required for different mechanisms through the coordination between the power mechanism, the gluing mechanism and the cutting mechanism. The linkage switching between pasting and cutting is realized by the displacement control in the thickness direction of the workpiece being bonded. The equipment has a high degree of automation, a simple and practical structure, and greatly improves the production efficiency.

[0102] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
