Description

Technical Field

[0001] The utility model relates to the technical field of glue dripping machines, and more particularly to a driving mechanism of a glue dripping machine. Background Art

[0002] When lamps and electronic components are produced and installed, they are mostly fixed by gluing. In order to further ensure the production quality of the products, the workshops are mostly dust-free workshops, and the processing of glue products is mostly done by direct liquid glue supply machinery and equipment.

[0003] After searching, the utility model patent with Chinese application number CN202220547893.1 discloses a driving mechanism of an automatic glue dispensing machine, including a conveying device for conveying the glue-dispensing product; a glue dispensing rack is slidably installed on the surface of the vertical frame, and a glue supply hose is connected to the outside of the glue dispensing rack; a frame is movably installed at the bottom end of the glue dispensing rack, and a glue coating roller is rotatably installed inside the frame, and the bottom end of the glue coating roller passes through the frame; a glue guide block is arranged between the glue dispensing rack and the glue coating roller, and a tension member is arranged between the glue guide block and the frame, which is used to coat the glue on the outer wall of the glue coating roller; a driving component is installed on the surface of the vertical frame; and an electronic control module is used to control the operation of the driving component.

[0004] When in use, the product to be glued is placed on the conveying equipment, and the conveying equipment transports the product to be glued. When the electronic control module detects the position of the product to be glued, when the product to be glued reaches the bottom of the frame, the driving component is used to move the glue frame downward on the surface of the vertical frame. The glue frame is driven downward by the glue frame, and the product can be glued on the surface of the product as the glue roller rotates during the movement. After the gluing is completed, the glue frame is moved upward by the driving component.

[0005] Since the electronic control module is installed on one side of the frame and there is a certain gap between the electronic control module and the frame, it is not convenient to accurately detect when the product to be glued has moved to the edge of the frame. It is not convenient to detect when the glue is finished through the electronic control module, and it is not convenient to accurately control it, which reduces its practicality. In addition, the product to be glued is placed inside the positioning groove. Since the size of the positioning groove is fixed, it is not convenient to position products of different sizes to be glued. Utility Model Content

[0020] Beneficial effects:

[0021] 1. The conveying equipment drives multiple placement plates and the products to be glued on the placement plates to move. When the edge of the product to be glued moves to the position of the glue coating roller, the top plate squeezes the top column, so that the top column squeezes the push switch, connects the push switch, connects the circuit connected to the motor, and makes the glue coating roller rotate and work. When the glue coating of the product to be glued is completed, the top plate separates from the top column, and the compression spring pushes the ring and the top column forward to separate the top column from the push switch, disconnecting the circuit connected to the motor, and thus the glue coating roller stops working.

[0035] Specifically, the conveying equipment 1 drives multiple placement plates 4 and the products to be glued on the placement plates 4 to move. When the edge of the product to be glued moves to the position of the glue coating roller 3, the top plate 6 squeezes the top column 9, causing the top column 9 to squeeze the press switch 11, connecting the press switch 11, connecting the circuit connected to the motor 15, and causing the glue coating roller 3 to rotate and work.

A scale line 20 is provided on the placement plate 4 to facilitate accurate adjustment of the position of the positioning plate 18.

[0037] Specifically, the positions of the two positioning plates 18 are adjusted by sliding the first convex plate 17 inside the first convex groove 16 so that the spacing between the two positioning plates 18 is equal to the width of the product to be glued, and the first screw 19 is tightened so that the bottom end of the first screw 19 is pressed against the bottom end of the first convex groove 16 to fix the first convex plate 17 and the positioning plate 18, thereby facilitating the positioning of products of different sizes.

[0038] See also Figure 3 The rear end of the fixing plate 5 is fixedly connected to the fixing frame 21, the interior of the fixing frame 21 is inserted with an inserting plate 22, the rear end of the inserting plate 22 is fixedly connected to the top plate 6, and the fixing frame 21 is threadedly connected with a second screw 23 that cooperates with the inserting plate 22.

[0039] Specifically, by inserting the inserting plate 22 into the interior of the fixed frame 21 and tightening the second screw 23, the side end of the second screw 23 is tightly fixed to the side end of the inserting plate 22, so that the top plate 6 of the corresponding length can be replaced according to the width of the product to be glued.

The telescopic rod of the electric cylinder 28 is connected to the top of the second convex plate 26, and the side end of the second convex plate 26 is fixedly connected to the side end of the glue box 13.

[0041] Specifically, the electric cylinder 28 drives the second convex plate 26 to move up and down, and the second convex plate 26 drives the glue box 13 and the glue roller 3 to move up and down, so as to adjust the height of the glue roller 3 according to the height of the product to be glued.

[0042] In summary, when the overall equipment is in use:

[0043] First, a certain amount of glue is transported to the inside of the glue storage tank 14 through the glue supply hose 30, and the glue inside the glue storage tank 14 is transported to the glue guide block 31 through multiple pins 32. The glue is evenly transmitted to the glue coating roller 3 through the glue guide block 31. Then, according to the width of the product to be glued, the plug plate 22 on the top plate 6 with the same width as the product to be glued is inserted into the inside of the fixed frame 21, and then the second screw 23 is tightened so that the side end of the second screw 23 is tightly pressed against the side end of the plug plate 22 to fix the plug plate 22 and the top plate 6. Then, the first convex plate 17 is slid inside the first convex groove 16, and the positioning plate 18 is adjusted to the appropriate position through the scale line 20, and the side ends of the two positioning plates 18 are flush with the two ends of the top plate 6. At this time, the distance between the two positioning plates 18 is equal to the width of the product to be glued, and then the second convex plate 26, the glue box 13 and the glue coating roller 3 are driven up and down by the electric cylinder 28. , according to the height of the product to be glued, the glue coating roller 3 is moved to a suitable height, and then the product to be glued is placed on the placement plate 4 between the two positioning plates 18, and the product to be glued is driven to move by the conveying equipment 1. When the top plate 6 moves to the position of the top column 9, the top column 9 is squeezed, so that the top column 9 squeezes the press switch 11, so that the press switch 11 is connected, and the circuit connected to the motor 15 is connected, and the motor 15 drives the glue coating roller 3 to rotate, so that the glue on the glue coating roller 3 is evenly coated on the corresponding product. When the glue coating on the product to be glued is completed, the top plate 6 is separated from the top column 9, and the compression spring 12 pushes the ring 8 and the top column 9 to move, so that the top column 9 is separated from the press switch 11, thereby disconnecting the circuit connected to the motor 15, and causing the motor 15 to stop working. When the next product to be glued moves to the position of the glue coating roller 3, the glue coating roller 3 motor 15 drives the glue coating roller 3 to rotate and apply glue.

[0044] In all the schemes mentioned above, the connection between the two components can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded.
