Description

[0002] The existing adhesive backing machine is mainly used for adhesive backing of hard flat products, and includes a jig and a manipulator. When in use, the hard flat product is fixed on the jig, and the adhesive backing is adsorbed by the manipulator, and then the adhesive backing is pressed down on the hard flat product by the manipulator, so that the adhesive backing of the hard flat product can be completed. However, if the adhesive backing is pressed down on the elastic rubber product with a curved surface by the manipulator, the elastic rubber product with a curved surface will undergo elastic deformation when under pressure, so that the adhesive backing cannot be smoothly attached to the elastic rubber product with a curved surface, resulting in the existing adhesive backing machine being unsuitable for adhesive backing of elastic rubber products with curved surfaces, and the adhesive backing can only be manually applied to the elastic rubber product with a curved surface by the operator with the help of a jig. However, when the operator manually applies adhesive backing to the elastic rubber product with a curved surface, the bonding efficiency is often very low due to manual fatigue during mass production.

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0025] like Figure 1-6As shown, a machine for gluing backing of elastic rubber products with curved surfaces comprises a turntable workbench 11, a rotary drive device 12 for driving the turntable workbench 11 to rotate, at least two fixtures 20 arranged circumferentially on the turntable workbench 11, a loading and unloading station 13, a bonding station 14, and a bonding device 30 located at the bonding station 14; the loading and unloading station 13 and the bonding station 14 are arranged circumferentially around the rotation axis of the turntable workbench 11, the fixture 20 rotates with the turntable workbench 11 and is transferred between the loading and unloading station 13 and the bonding station 14; the bonding device 30 comprises an X-axis movable seat 31, an X-axis driving mechanism 40 for driving the X-axis movable seat 31 to move along the front-rear direction, a Z-axis movable seat 61 located above the turntable workbench 11, and a Z-axis driving mechanism 40 installed on the X-axis movable seat 31 and used to drive the Z-axis movable seat 61 to rise and fall. Structure 62, a flattening assembly 70, and two flattening finger mechanisms 80 respectively installed on the Z-axis movable seat 61; the flattening assembly 70 includes a rolling unit 71, two support frames 72, and two Y-axis driving mechanisms 73 installed on the Z-axis movable seat 61 and corresponding to the two support frames 72 respectively; the Y-axis driving mechanism 73 is used to drive the corresponding support frames 72 to move along the left and right directions; the rolling unit 71 includes two rollers 74 respectively corresponding to the two support frames 72, and the rollers 74 are rotatably installed on the corresponding support frames 72; the two flattening finger mechanisms 80 are respectively arranged on both sides of the rolling unit 71, and are both used to press the end of the arc-shaped elastic rubber product against the adjacent rollers 74; the jig 20 is provided with a product placement area 21 and a back glue placement area 22 arranged along the front-to-back direction when the jig 20 is located at the bonding station 14.

[0026] When the jig 20 is located at the loading and unloading station 13, the curved elastic rubber product can be placed manually in the product placement area 21 with the bonding surface facing downward, and then the outer film layer of the adhesive is torn off and placed in the adhesive placement area 22 of the jig 20 with the adhesive surface facing upward, and then the turntable workbench 11 is driven to rotate by the rotary drive device 12. At this time, the jig 20 rotates to the bonding station 14 with the turntable workbench 11, and then the Z-axis movable seat 61 is driven to descend by the Z-axis driving mechanism 62, and the curved elastic rubber product is flattened downward by the rolling unit 71, and then the curved elastic rubber product is respectively flattened by the two flattening finger mechanisms 80. The two ends of the rubber product are pressed against the roller 74 so that the curved elastic rubber product embraces the surface of the rolling unit 71, and then the Z-axis driving mechanism 62 drives the Z-axis movable seat 61 to be lifted upward, and then the X-axis driving mechanism 40 drives the X-axis movable seat 31 to move backward, so that the curved elastic rubber product is facing the back glue, and then the Z-axis driving mechanism 62 drives the Z-axis movable seat 61 to descend, and the curved elastic rubber product is pressed downward. After the lowest point of the curved elastic rubber product is in contact with the back glue, the two Y-axis driving mechanisms 73 drive the two support frames 72 to move in opposite directions, and the roller 74 moves with The support frame 72 moves and rolls on the curved elastic rubber product. While the roller 74 rolls, the flattening finger mechanism 80 is released, so that the area on the curved elastic rubber product rolled by the roller 74 is bonded to the adhesive backing. After the curved elastic rubber product is rolled by the roller 74 and is flatly bonded to the adhesive backing, the rotary drive device 12 drives the turntable table 11 to rotate, so that the jig 20 rotates with the turntable table 11 to the loading and unloading station 13. At this time, the product with adhesive backing can be taken out manually, and then the work can be continued in the above manner. Therefore, the curved elastic rubber product provided by the present invention is bonded to the adhesive backing. The gluing machine adopts a combination of a turntable workbench 11, a rotary drive device 12, a fixture 20, a loading and unloading station 13, a bonding station 14, and a bonding device 30, and the bonding device 30 adopts a combination of a flattening component 70 and two flattening finger mechanisms 80, which can replace manual gluing on curved elastic rubber products, thereby improving the bonding efficiency during mass production; and, through the consistency of the front-to-back movement stroke of the X-axis moving seat 31 of the bonding device 30, the bonding position of the back glue of each product can be ensured to be consistent, avoiding the different bonding positions of the back glue of each product due to manual techniques or manual misoperation, and improving product quality.

When in use, the lifting seat 81 can be driven to move up and down by the lifting drive device 82, thereby driving the flattening finger 83 to move up and down, and the flattening finger 83 can also be driven to move in the left and right directions by the translation drive device 84, so that the position of the flattening finger 83 can be flexibly adjusted, so that the flattening finger 83 can press the end of the arc-shaped elastic rubber product against the adjacent roller 74, and when the roller 74 rolls the arc-shaped elastic rubber product, the flattening finger 83 can move synchronously with the roller 74 to release the arc-shaped elastic rubber product.

[0028] The lifting drive device 82 includes a first through-type screw motor; the screw of the first through-type screw motor is vertically arranged; the lifting seat 81 can be installed on the Z-axis movable seat 61 in a liftable manner, and is threadedly connected with the screw of the first through-type screw motor. When in use, the screw of the first through-type screw motor rotates forward, thereby driving the lifting seat 81 to rise, and the screw of the first through-type screw motor rotates reversely, thereby driving the lifting seat 81 to fall. By using the first through-type screw motor in the lifting drive device 82, the lifting seat 81 can be driven to rise and fall, and assembly time can be saved.

[0029] The lifting seat 81 may be provided with a first nut, which can be threadedly connected to the screw of the first through-type screw motor through the first nut. Of course, in addition to this, the lifting seat 81 may also be provided with a first threaded hole, which can also be threadedly connected to the screw of the first through-type screw motor through the first threaded hole.

[0030] Specifically, the body of the first through-type screw motor is fixed on the Z-axis movable seat 61. The Z-axis movable seat 61 is provided with a first guide rail 66 extending along the vertical direction, and the lifting seat 81 is provided with a first slider slidably matched with the first guide rail 66, so as to improve the smoothness and stability of the lifting seat 81.

When in use, the second through-type screw motor 85 works to drive the translation seat 86 together with the leveling finger 83 to move in the left-right direction. By using the second through-type screw motor 85 and the translation seat 86 in the translation drive device 84, the leveling finger 83 can be driven to move in the left-right direction, and assembly time can be saved.

[0032] The translation seat 86 may be provided with a second nut to be threadedly connected to the screw of the second through-type screw motor 85. Of course, in addition to this, the translation seat 86 may also be provided with a second threaded hole to be threadedly connected to the screw of the second through-type screw motor 85 using the second threaded hole.

[0033] Specifically, the lifting seat 81 is provided with a second guide rail 87 extending in the left-right direction, and the translation seat 86 is provided with a second slider slidably matched with the second guide rail 87, thereby improving the smoothness and stability of the movement of the translation seat 86.

[0034] The end of the flattening finger 83 close to the rolling unit 71 is provided with a pressing arc surface 88 to match the roller 74 so that the end of the elastic rubber product with curved surface can be firmly pressed against the roller 74. As a further preferred embodiment of the present invention, the bottom of the pressing arc surface 88 is convex relative to the top toward the rolling unit 71, so that the bottom of the pressing arc surface 88 can also be used to play a supporting role, so that the end of the elastic rubber product with curved surface can be lifted and pressed against the roller 74 by the bottom of the pressing arc surface 88, and the stability of pressing the end of the elastic rubber product with curved surface can be further improved.

[0035] Specifically, the rear portion of the flattening finger 83 is fixed on the translation seat 86 , and the front portion of the flattening finger 83 is provided with an outer convex portion protruding toward the rolling unit 71 , and the pressing arc surface 88 is formed on the outer convex portion.

[0036] The jig 20 includes a receiving seat 23 and two positioning devices 24; the product placement area 21 and the adhesive placement area 22 are both formed on the receiving seat 23; the two positioning devices 24 are respectively placed on both sides of the receiving seat 23 and are used to position the curved elastic rubber product. When in use, the curved elastic rubber product can be placed in the product placement area 21 of the receiving seat 23, and the curved elastic rubber product can be positioned by the two positioning devices 24, so as to avoid the displacement of the curved elastic rubber product during the rotation of the turntable worktable 11.

[0037] The positioning device 24 includes a positioning seat 25 and a positioning seat driving component 26. The positioning seat driving component 26 is fixed on the turntable workbench 11 and is used to selectively drive the positioning seat 25 to move toward or away from the receiving seat 23; the positioning seat 25 is provided with a positioning groove 27 for the end of the arc-shaped elastic rubber product to be embedded, and the arc-shaped elastic rubber product is placed in the product placement area 21 of the receiving seat 23, and then the positioning seat driving component 26 of the two positioning devices 24 drives the positioning seat 25 to move toward the receiving seat 23, so that the arc-shaped elastic rubber product extending out of the receiving seat 23 is inserted into the positioning groove 27. The two ends of the rubber product are respectively embedded in the positioning grooves 27 of the positioning seats 25 of each positioning device 24, so that the positioning grooves 27 limit the arc-shaped elastic rubber product and prevent the arc-shaped elastic rubber product from shifting. When the jig 20 with the arc-shaped elastic rubber product is rotated to the bonding station 14, the positioning seat driving components 26 of the two positioning devices 24 drive the positioning seat 25 to move away from the receiving seat 23. At this time, the rolling unit 71 can be lowered to flatten the arc-shaped elastic rubber product, and the two ends of the arc-shaped elastic rubber product can be pressed against the roller 74 by the two flattening finger mechanisms 80.

[0038] In this embodiment, the positioning seat driving component 26 includes a translation driving cylinder, and the positioning seat 25 is connected to the piston rod of the translation driving cylinder, so that the piston rod of the translation driving cylinder moves toward the receiving seat 23, and the positioning seat 25 can be driven to move toward the receiving seat 23, and the piston rod of the translation driving cylinder moves toward the direction away from the receiving seat 23, and the positioning seat 25 can be driven to move away from the receiving seat 23. Of course, in addition to this, the positioning seat driving component 26 can also adopt a combination of a motor and a conveying chain assembly, and can also selectively drive the positioning seat 25 to move toward or away from the receiving seat 23, but the positioning seat driving component 26 adopts a translation driving cylinder, which is the most preferred embodiment of the present invention and can be convenient for connection.

[0039] The positioning seat driving component 26 also includes a mounting seat 28 provided on the turntable workbench 11, and the cylinder body of the translation driving cylinder is fixed on the mounting seat 28.

The adjusting groove 55, the transverse adjusting groove 55 extends along the length direction of the product placement area 21, and the pressing plate 50 is provided with a longitudinal adjusting groove 56 extending along the width direction of the product placement area 21, and the connecting component includes an adjusting screw 57 penetrating into the corresponding transverse adjusting groove 55 and the longitudinal adjusting groove 56 of the pressing plate 50, and an adjusting nut 58 threadedly connected to the adjusting screw 57 and resting on the pressing plate 50. By combining the pressing plate 50, the connecting component, and the locking component as the adjusting component, the position of the mounting seat 28 and the translation driving cylinder can be adjusted according to the length of the product, which can be applicable to products of different lengths and can expand its scope of application.

[0041] The receiving seat 23 is provided with a positioning component for positioning the adhesive backing, so that the adhesive backing can be prevented from shifting by the positioning component.

[0042] Among them, the positioning component can adopt a vacuum adsorption disk or the like, as long as it can be used to position the back glue. As a preferred embodiment of the present invention, the positioning component is two positioning columns 29 arranged on the supporting seat 23, and the two positioning columns 29 are respectively used to penetrate into the two through holes of the bottom film layer of the back glue. By adopting the positioning column 29 as the positioning component, it can play a positioning role and reduce costs.

When in use, the support frame 72 can be driven to move in the left-right direction by the operation of the third through-type screw motor. By adopting the third through-type screw motor for the Y-axis driving mechanism 73, the support frame 72 can be driven to move in the left-right direction and assembly time can be saved.

[0044] The support frame 72 may be provided with a third nut to be threadedly connected to the screw of the third through-type screw motor through the third nut. Of course, in addition to this, the support frame 72 may also be provided with a third threaded hole to be threadedly connected to the screw of the third through-type screw motor through the third threaded hole.

[0045] Of course, in addition to this, the Y-axis driving mechanism 73 can also adopt a cylinder, etc., which can also drive the support frame 72 to move along the left and right directions. However, using a third through-type screw motor for the Y-axis driving mechanism 73 is the most preferred embodiment of the present invention, which can improve the accuracy of the movement of the support frame 72 and save assembly time.

[0046] Specifically, the Z-axis movable seat 61 is provided with a third guide rail extending in the left-right direction, and the support frame 72 is provided with a third slider slidably matched with the third guide rail, thereby improving the smoothness and stability of the movement of the support frame 72.

[0047] The support frame 72 includes two side plates arranged opposite to each other, a top plate arranged between the tops of the two side plates, a connecting shaft 75 connected between the lower parts of the two side plates, and a bearing; the inner ring of the bearing is fixedly sleeved on the connecting shaft 75, and the roller 74 is fixedly sleeved on the outer ring of the bearing, so that the rotation of the roller 74 can be smoother. The third slider is arranged on the top plate. As a further preferred embodiment, the connecting shaft 75 is fixedly sleeved with two bearings, and a limiting sleeve sleeved on the connecting shaft 75 is abutted between the inner ring of the bearing and the side plate close to the bearing, and the roller 74 is provided with a built-in groove for the connecting shaft 75 to pass through, and both ends of the roller 74 are provided with matching grooves that are connected with the built-in groove and are interference-fitted with the outer ring of the bearing, so as to improve the stability of the rotation of the roller 74.

[0048] The machine for gluing curved elastic rubber products further comprises a frame, the X-axis driving mechanism 40 comprises a driven pulley 41 rotatably mounted on the frame, a driving pulley 42, a pulley driving motor 43 for driving the driving pulley 42 to rotate, and a conveyor belt 44; the conveyor belt 44 is wound around the driving pulley 42 and the driven pulley 41, and the X-axis movable seat 31 is movably mounted on the frame and fixedly connected to the conveyor belt 44. When in use, the pulley driving motor 43 works and can drive the conveyor belt 44 through the driving pulley 42, thereby driving the X-axis movable seat 31 to move along the front-rear direction.

[0049] Specifically, the driven pulley 41 is rotatably mounted on the top of the frame, the body of the pulley drive motor 43 is fixed on the top of the frame, the frame is provided with a fourth guide rail extending along the front-to-back direction, and the X-axial movable seat 31 is provided with a fourth slider slidingly matched with the fourth guide rail to improve the smoothness and stability of the movement of the X-axial movable seat 31.

[0050] Of course, in addition to this, the X-axial driving mechanism 40 can also adopt a cylinder, etc., which can also drive the X-axial movable seat 31 to move along the front and rear direction. However, the X-axial driving mechanism 40 adopts a combination of a driven pulley 41, a driving pulley 42, a pulley drive motor 43, and a conveyor belt 44. It is the most preferred embodiment of the present invention, which can improve the stability of the movement of the X-axial movable seat 31 and increase the carrying capacity.

[0051] The Z-axis driving mechanism 62 includes a primary cylinder 63, a follower seat 64, and a secondary cylinder 65.

The follower seat 64 can be installed on the X-axis movable seat 31 in a liftable manner and is fixedly connected to the piston rod of the primary cylinder 63. The cylinder body of the secondary cylinder 65 is fixed on the follower seat 64, and the piston rod of the secondary cylinder 65 is vertically arranged. The Z-axis movable seat 61 is fixedly connected to the piston rod of the secondary cylinder 65. In the process of covering the arc-shaped elastic rubber product with the rolling unit 71, the follower seat 64 is first driven to descend by the primary cylinder 63, and the Z-axis movable seat 61 descends with the follower seat 64, and the roller 74 of the rolling unit 71 is used to press the arc-shaped elastic rubber product The flattening finger 83 presses the end of the curved elastic rubber product against the roller 74 of the rolling unit 71, and can pull and flatten the part of the curved elastic rubber product between the two rollers 74, so that the curved elastic rubber product is more closely attached to the two rollers 74. When the X-axis driving mechanism 40 drives the X-axis movable seat 31 to move backward so that the curved elastic rubber product is facing the back glue, the piston rods of the primary cylinder 63 and the secondary cylinder 65 move downward, driving the Z-axis movable seat 61 to perform a secondary descent so that the lowest point of the curved elastic rubber product is pressed down to fit the back glue, and a tight press fit is formed between the roller 74 and the lowest point of the curved elastic rubber product, so that the curved elastic rubber product can be more closely attached to the back glue during subsequent rolling and pressing. By combining the primary cylinder 63, the follower seat 64, and the secondary cylinder 65 in the Z-axis driving mechanism 62, the laminating effect can be improved and the cost can be reduced.
