[0020] It should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "setting" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0021] like Figure 1As shown, the structure of the single-sided gluing device for the rubber composite plate includes a frame, a pair of gluing rollers arranged in the frame 1, the gluing rollers include a glue-distributing roller 21 and a glue-pressing roller 22, a glue tube 3 is arranged in parallel at the upper part of the gap between the two, and a plurality of drip holes are arranged on the tube body of the glue tube 3, a first conveyor belt for conveying the rubber composite plate a is arranged below the glue-pressing roller 22, and the glue-pressing roller 22 hydraulically applies the glue on the plate surface, a first conveyor is arranged at the front end of the frame 1, and a first manipulator 50 is arranged at the upper part thereof for grabbing and conveying the rubber composite plate a to the first conveyor belt, a second conveyor is arranged at the rear end of the frame 1, and a second manipulator 60 is arranged at the upper part thereof for grabbing and conveying the rubber composite plate a' after gluing to the second conveyor belt 7, and the second conveyor belt 7 is connected to the vulcanizer 8.

[0022] Its working principle is as follows: the gluing mechanism of the device is composed of a pair of gluing rollers arranged in a frame 1, and the pair of gluing rollers includes a glue-distributing roller 21 and a glue-pressing roller 22. The glue drops from the dripping hole of the glue tube 3 above, and the gap between the pair of rollers forms an entrance for the glue roller to press the glue into a film. When the board surface passes under the glue-pressing roller 22, the glue is pressed onto the rubber layer. In order to improve the coating efficiency, a first conveyor belt is arranged under the pair of rollers to automatically transport the board. A first conveyor and a second conveyor are respectively arranged in front of and behind the first conveyor belt. The manipulator is used to grab the board to achieve rapid transfer.

[0023] It should be noted that the glue-distributing roller 21 of the glue-coating roller pair is a steel roller and the glue-pressing roller 22 is a polyurethane rubber roller, and the two are arranged obliquely, that is, the glue-pressing roller 22 contacts the board surface, and the glue-distributing roller 21 is suspended in the air; the glue-pressing roller 22 and the board surface move in opposite directions at the tangential contact point, that is, the glue is pressed onto the board surface by a reverse coating method.

[0024] In the structure constituting the above-mentioned single-sided gluing device for rubber composite plates,

[0025] In one embodiment, the specific structure of the first conveyor belt is composed of a mobile platform 41 and a lead screw 42 driving the mobile platform 41 to move. The lead screw 42 is a ball screw 42 driven by a servo motor. The mobile platform 41 is mounted on a slider of the lead screw 42. Tracks are arranged on both sides of the frame 1. Both sides of the mobile platform 41 are arranged in the tracks to play a role of horizontal support and guide sliding. A plurality of first pneumatic suction cups 43 are arranged on the surface of the mobile platform 41. In this way, the rubber composite plate a is placed on the mobile platform 41 and is firmly positioned to prevent the position change when the rubber pressing roller 22 is passed, causing disorder in the gluing.

[0026] ——Preferably, an adjustment mechanism is provided at the front end of the first conveyor belt, and the adjustment mechanism includes first pneumatic pushers 44 respectively provided on both sides of the frame 1. After the first pneumatic pushers 44 are extended, they push the edge of the rubber composite plate a to regularize its position in the mobile platform 41, that is, the first manipulator 50 of the first conveyor grabs the rubber composite plate to be processed into the mobile platform 41. The position of the plate is irregular when grabbing, and the positioning of the plate is not unique after being placed on the mobile platform 41. Therefore, before entering the pressure coating process, it is necessary to regularize it in the mobile platform 41, and the first pneumatic pushers 44 on both sides of the frame 1 are extended at the same time to push the edge of the plate to make it uniquely positioned in the mobile platform 41, so as to ensure the standardization of the subsequent pressure coating process;

[0027] ——Furthermore, the first conveyor includes a frame 51, a first power rail 52 arranged on the upper part of the frame 51, which connects the material pile and the first conveyor belt entrance, and the first manipulator 50 includes a lifting grab plate 54 connected to the first vertical cylinder 53, and a plurality of second pneumatic suction cups 55 are arranged on the surface of the lifting grab plate 54, that is, the upper part of the lifting grab plate 54 is connected to the piston rod of the first vertical cylinder 53 to achieve up and down movement, and the bottom surface of the grab plate 54 is provided with a second pneumatic suction cup 55, which is fitted with the rubber composite plate and then grabbed, and the mounting bracket 56 of the first vertical cylinder 53 is placed in the first power rail 52, that is, the mounting bracket 56 is connected to the first power rail 52 through a slider, so that the first manipulator 50 moves along the rail to continuously transport the rubber composite plate a to be processed from the material pile to the first conveyor belt;

[0028] ——Similarly, the second conveyor includes a frame 61, a second power rail 62 arranged on the upper part of the frame 61, which connects the first conveyor belt outlet and the second conveyor belt 7, and the second manipulator 60 includes a lifting and positioning plate 63, the upper part of the lifting and positioning plate 63 is connected to the second vertical cylinder 64, and the mounting bracket 67 of the second vertical cylinder 64 is placed in the second power rail 62. A plurality of crank arms are respectively arranged on both sides of the lifting and positioning plate 63, and a second pneumatic pusher 65 is arranged at the lower end of the crank arm. The front end of the second pneumatic pusher 65 has a probe 66, and the probe 67 is arranged on the lower end of the second pneumatic pusher 65. 6 is extended and inserted into the bottom of the rubber composite plate a' after being coated with glue. Different from the first conveyor, the gripping method of the second manipulator 60 is changed. Since the surface of the rubber composite steel plate has been coated with glue, the vacuum suction cup gripping of the first manipulator 50 is not applicable. Therefore, the second manipulator 60 adopts a pusher plus a front probe to lift the glued composite plate and transport it through the second power guide rail 62. Finally, the glued composite plate a' is placed in the second conveyor belt 7 and transported to the vulcanizer 8 for curing process. Figure 1 The mobile platform 41 indicated by the dotted line in the figure transports the glue-coated composite board a' to the docking position of the second conveyor belt 7;

[0029] In one embodiment, the two sides of the first conveyor belt are provided with enclosures 71, the enclosures 71 support the bases of the glue-distributing roller 21 and the glue-pressing roller 22, and the upper part of the triangular enclosure 71 is provided with a first inclined guide rail 72 and an L-shaped side plate 73, the long side of the L-shaped side plate 73 is installed in the first inclined guide rail 72, and the short side of the L-shaped side plate 73 is used to fix the end of the glue-pressing roller 22, that is, the glue-pressing roller 22 can move along the first inclined guide rail 72, adjust the pressure, achieve uniform and stable glue coating, and ensure the reverse coating effect;

[0030] A second inclined guide rail 74 is provided on the upper part of the long side of the L-shaped side plate 73, and the side plate 75 at the end of the glue-distributing roller 21 is installed in the second inclined guide rail 74, so that the glue-distributing roller 21 and the glue-pressing roller 22 can move synchronously, ensuring that the gap between the two does not change, and the glue coating thickness can be kept constant;

[0031] ——Furthermore, a push-pull cylinder 76 is provided at the end of the long side of the L-shaped side plate 73, and the side plate 75 of the glue-distributing roller 21 is connected to one end of a screw rod 77, the screw rod 77 is parallel to the long side of the L-shaped side plate 73, and a hand wheel 78 is provided at the other end thereof, and the screw rod of the hand wheel 78 is perpendicular to the screw rod 77 and is threadedly engaged, that is, by rotating the hand wheel 78, the screw rod 77 is driven to move along the long side direction of the L-shaped side plate 73, and the screw rod 77 synchronously drives the glue-distributing roller 21 to change the gap between the glue-distributing rollers, and the thickness of the glue liquid rolling coating changes accordingly, so as to adapt to the glue coating requirements of different rubber composite plates and improve the application range of the equipment;

[0032] ——Preferably, the device further comprises a plc controller 9, which is used to integrate the linkage control of all electrical equipment. Specifically, it is electrically connected to the glue coating rollers (glue-distributing roller 21, glue-pressing roller 22), the first conveyor belt, the first conveyor, the second conveyor belt, the second conveyor, and the power mechanism of the first manipulator and the second manipulator. The electrical connection method can use the existing technology, including necessary solenoid valves, sensors, power lines, communication lines and other components, which are used to control the working rhythm, such as the coating and pressing speed of the glue coating rollers, the power pump connected to the glue liquid pipe 3 above the glue coating rollers, the transmission speed of the first conveyor belt and the second conveyor belt, the running speed of the first manipulator and the second manipulator, and the start and stop, so that they are interconnected and closely coordinated;

[0033] ——The above-mentioned plc controller 9 includes position sensors 91 arranged at the front and rear ends of the first conveyor belt, the front and rear ends of the first conveyor and the second conveyor, and the upper and lower ends of the first manipulator and the second manipulator. The automatic working process of the above-mentioned equipment is as follows: when the first manipulator and the second manipulator grab the composite board, the upper and lower stroke positions send signals to the plc controller through sensors to control the start and stop of the first manipulator; the sensor of the front and rear movement stroke of the first conveyor along the first power rail is used to feedback the signal from the composite board being grabbed to being conveyed to the first conveyor belt; the front end sensor of the first conveyor belt monitors the signal from the composite board falling into the mobile platform 41; the rear end sensor of the first conveyor belt monitors the completion of the gluing process of the composite board, and transmits the signal of the gluing roller with the mobile platform 41; the sensor of the front and rear movement stroke of the second conveyor along the second power rail is used to feedback the signal from the composite board being lifted to being conveyed to the second conveyor belt, and a sensor can be set at the front end of the second conveyor belt to detect the composite board after falling into the glue, so as to start the second conveyor belt and convey the composite board into the vulcanizer.
