Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of a general device for coating a fluid on a surface and a special device for manufacturing cables, and specifically relates to a rubber head device for an electric coating robot. Background Art
[0002] There are many types of national standard aluminum-steel bare conductors currently available in my country, and the models are large and small; each place will choose the appropriate aluminum-steel bare conductor model according to different environments and scenarios, which leads to inconsistent models of aluminum-steel bare conductors used in most places; each manufacturer has also developed various structures of electric coating robot coating head structures to adapt to various models, including: two-petal upper and lower opening and closing structure and two-petal left and right opening and closing structure.
[0003] The two-petal upper and lower opening and closing structure has two ways of opening and closing. The first is that the two petals are opened or closed in the vertical up and down directions of the machine at the same time; the second is that one petal is fixed and the other petal is opened or closed to the top or bottom of the machine; both of these opening and closing methods are also for the convenience of inserting the wire into the pet head, so the structural space for the upper and lower opening of the pet head needs to be large enough, and the upper and lower opening and closing needs to reserve an open space on one side for putting in and taking out the cable, so when designing the upper and lower opening and closing connectors and the movable structure of the pet head, they can only be placed on one side, which will cause the force on the open side to be much weaker when closing, and the pet head on this open side will not be able to close properly, and there will be glue leakage if the pet head does not close properly.
[0004] The two-flap left and right opening and closing structure is that the two-flap rubber head opens or closes to the horizontal left and right sides of the machine at the same time. There are two ways of opening and closing. The first is that the two-flap rubber head opens or closes to the horizontal left and right directions of the machine at the same time above the cable; the second is that the two-flap rubber head opens or closes to the horizontal left and right directions of the machine at the same time below the cable; both of these opening and closing methods are also for the convenience of inserting the wire into the rubber head. In this way, the left and right opening structure of the rubber head needs to reserve an open space on one side for putting in and taking out the cable. Therefore, when designing the left and right opening and closing connectors and the moving structure of the rubber head, they can only be placed on the upper or lower side. This will cause the force on the open upper or lower side to be much weaker when closing, and the rubber head on this open side will not be able to close up and down, and there will be glue leakage if the rubber head does not close in place.
[0005] At the same time, the device of the glue coating head is usually centered at the entrance; however, if the centering device and the glue outlet nozzle are set close to each other in order to ensure uniform thickness, the uniformity of the glue will be affected due to the insufficient size of the glue filling cavity when the pressure of the glue extrusion device changes, and serious problems such as bubbles will be generated, which can only be solved by reducing the speed of the equipment; if the size of the glue filling cavity is guaranteed, the thickness of the glue outlet cannot be guaranteed due to inaccurate centering.

DETAILED DESCRIPTION
[0037] The present invention is further described in detail below in conjunction with the accompanying drawings.
[0038] like Figure 1 to Figure 8The embodiment of the present invention shown in the figure comprises: a bare stranded wire pre-pressing unit 1-1, a glue head opening and closing driving unit 1-2, a coating unit 1-3, a glue equalizing cavity 1-4, a bare stranded wire fixing wall 1-5 in the cavity, a glue outlet 1-6, a glue coating cavity 1-7, a connecting portion 1-8 and a bare stranded wire 1-9, wherein the coating unit 1-3 comprises: an adapter block fixing base 3-1-1 and a movable adapter block mounting seat, wherein the adapter block fixing base 3-1-1 and the movable adapter block mounting seat are hinged, and the glue head opening and closing The transmission push plate 2-1-11 in the driving unit 1-2 is connected to the movable adapter block mounting seat, thereby driving the movable adapter block mounting seat in the coating unit 1-3 to open or close. When the rubber head opening and closing driving unit 1-2 drives the movable adapter block mounting seat to close, the connecting plate 1-1-3 in the bare stranded wire pre-pressing unit 1-1 drives the guide roller 1-1-11 in the bare stranded wire pre-pressing unit 1-1 to press the bare stranded wire 1-9 from one side, thereby performing preliminary centering on the bare stranded wire;

The bare stranded wire fixing wall 1-5, the connecting wall and the glue outlet nozzle 1-6 in the cavity are integrally formed, so the glue coating cavity 1-7 is formed between the bare stranded wire fixing wall 1-5 and the glue outlet nozzle 1-6 in the cavity; according to the installation position, the fixed glue outlet component group is divided into a first cable adapter glue coating block 3-1-14, a second cable adapter glue coating block 3-1-13 and a third cable adapter glue coating block 3-1-15; the first cable adapter glue coating block 3-1-14, the second cable adapter glue coating block 3-1 -13 and the third cable adapter glue block 3-1-15 are respectively installed on the side of the bare stranded wire outlet of the glue cavity 1-4 in the adapter block fixed base 3-1-1, the first movable adapter block mounting seat 3-1-12 and the second movable adapter block mounting seat 3-1-16; after closing, the first cable adapter glue block 3-1-14, the second cable adapter glue block 3-1-13 and the third cable adapter glue block 3-1-15 form a complete glue cavity 1-7, the first cable adapter glue block 3-1-14 constitutes a 180° range of the glue cavity 1-7, the second cable adapter glue block 3-1-13 and the third cable adapter glue block 3-1-15 respectively constitute a 90° range of the glue cavity 1-7.
[0053] In this embodiment, each set of hose interfaces 3-1-17 is at an angle of 90°, so that the colloid in the colloid-distributing cavity 1-4 is more uniform.
[0054] In this embodiment, each group of hose interfaces 3-1-17 has two hose interfaces 3-1-17, and the two hose interfaces 3-1-17 are arranged along the length direction of the bare stranded wire 1-9, and each hose interface 3-1-17 is connected to an independent glue extrusion source, so that when the pressure of one or several glue extrusion sources fluctuates, the uniformity of the glue in the glue-distributing cavity 1-4 can still be guaranteed; at the same time, it is precisely because the bare stranded wire fixed wall 1-5 in the cavity used to center the bare stranded wire 1-9 is only a few millimeters away from the glue outlet nozzle 1-6 that the axial length of the glue-distributing cavity 1-4 can be increased, thereby further ensuring the uniformity and safety factor, and improving the overall operating speed of the glue head equipment.
[0055] In this embodiment, a fisheye bearing 3-1-2 is provided between the second pin 3-1-3 and the first end of the base connecting rod 3-1-9.
[0056] In this embodiment, a fisheye bearing 3-1-10 is provided between the third pin 3-1-11 and the second end of the base connecting rod 3-1-9.
[0057] When it is necessary to replace the bare stranded wire (cable), the cable model spacer 1-1-9, the second cable adapter glue block 3-1-13, the first cable adapter glue block 3-1-14 and the third cable adapter glue block 3-1-15 are replaced accordingly according to the diameters of the different cables. The second cable adapter glue block 3-1-13, the first cable adapter glue block 3-1-14 and the third cable adapter glue block 3-1-15 are used to evenly wrap the aluminum-steel bare wire to its fixed center so that the insulating coating glue is evenly coated. The replacement of the cable model spacer 1-1-9 is to ensure that the guide roller 1-1-11 can better contact and guide the aluminum-steel bare wires of different diameters. Combined with the glue head model identification PCB board 1-1-8, it can identify the corresponding aluminum-steel bare wire diameter parameters after each replacement.
[0058] During operation, as the rubber head opening and closing drive motor 2-1-1 rotates, the nut of the ball screw assembly 2-1-8 drives the transmission push plate 2-1-11 to perform up and down transmission movements, thereby simultaneously driving the push plate connecting rod 2-1-12, the base connecting rod 3-1-9 and the movable adapter block mounting seat (the first movable adapter block mounting seat 3-1-12 and the second movable adapter block mounting seat 3-1-16) to move, and the movable adapter block mounting seat (the first movable adapter block mounting seat 3-1-12 and the second movable adapter block mounting seat 3-1-16) performs a 1 / 4 circle opening and closing movement with the stabilizing rod pin 3-1-8 as the center, clamping the bare stranded wire (cable) in the space surrounded by the bare stranded wire fixed wall 1-5 in the cavity; as the bare stranded wire and the glue nozzle 1-6 produce relative displacement, the coating material is evenly coated on the outside of the bare stranded wire with equal thickness.
