Description

Technical Field

[0001] The utility model relates to a glue pouring device, in particular to a glue pouring device based on PLC system control. Background Art

[0002] Glue dispensing systems controlled by a PLC (Programmable Logic Controller) are automated devices widely used in the manufacturing industry, particularly in the electronics, automotive, home appliance, aviation, medical device, new energy, and semiconductor industries. They are used to accurately and efficiently apply and dispense adhesives (such as silicone gels, epoxies, sealants, hot melt adhesives, and other materials). These systems combine the flexibility and precise control capabilities of a PLC with advanced motion control technology to ensure consistent and high-quality glue application.

[0003] Existing glue filling devices generally suck the raw materials required for glue filling and then perform the filling operation through a filling mechanism. If there is air in the raw materials required for glue filling, bubbles are easily generated during the glue coating operation, resulting in poor colloid curing effect. In addition, in a high temperature environment, the bubbles may further expand or burst, seriously affecting the stability and reliability of the product.

[0004] Based on this, it is necessary to design a glue filling device controlled by a PLC system that can extract the air from the glue-coated raw materials. Utility Model Content

[0005] The technical implementation scheme of the present utility model is: a glue filling device based on PLC system control, including an organism, a human-machine controller, a glue coating device, a discharge pipe, a feed funnel, a material box, a vacuum device, a feed pipe, a material pump, a transmission box and an extrusion assembly. The glue coating device is movably provided on the top of the body, and a human-machine controller for controlling the glue coating device to perform glue coating according to preset instructions is provided on one side of the body. A material box is provided at the lower part of the body, and a feed funnel is connected to one side of the material box. A vacuum device for exhausting air in the material box is provided on the material box. The discharge end of the material box is connected to the transmission box installed on the body through the feed pipe. The feed pipe is provided with a material pump for sucking the raw materials in the material box into the transmission box. The discharge end of the transmission box is connected with the discharge pipe, and the transmission box is provided with an extrusion assembly. The raw materials required for gluing in the transmission box are transported to the gluing device through the discharge pipe for gluing operation after the extrusion action of the extrusion assembly.

[0006] Optionally, the extrusion assembly includes a cylinder and a rubber pressure plate. The cylinder is provided on the top of the transmission box and is mounted on the machine body through a rod-shaped stand. The movable end of the cylinder piston rod extends into the transmission box and its end is connected to the rubber pressure plate.

[0007] Optionally, the outer diameter of the rubber pressing plate is adapted to the inner diameter of the transmission box.

[0008] Optionally, a solenoid valve is provided between the discharge end of the transmission box and the discharge pipe.

[0009] Optionally, it further includes a vertical clamping plate and a telescopic rod. The telescopic rods are symmetrically arranged on both sides of the body. The movable ends of the telescopic rods are connected to the vertical clamping plates, and the vertical clamping plates are slidably matched with the top plane of the body.

[0010] Optionally, it also includes a transverse clamping plate, a triangular plate and a connecting screw. The connecting screw is slidably arranged on the vertical clamping plate, the end of the connecting screw facing away from the vertical clamping plate is connected to the triangular plate, and the triangular plate is connected to the transverse clamping plate.

[0011] Optionally, universal wheels are provided at the bottom of the machine body for easy movement.

[0012] Compared with the existing technology, the utility model has the following advantages: 1. The paint is input into the material box through the feeding funnel, and the air in the material box is extracted by the vacuum device to obtain the paint in a vacuum state. The paint in the material box is sucked into the transmission box by the extraction pump, and the rubber pressure plate is driven by the extension movement of the cylinder piston rod to squeeze the paint in the transmission box into the discharge pipe. The paint in the discharge pipe is applied to the workpiece by the glue coating device, thereby avoiding the generation of bubbles during the glue coating operation.

[0013] 2. The two vertical clamping plates are driven to move closer to or away from each other through the telescopic movement of the telescopic rod, and the connecting screw is adjusted by sliding, thereby driving the triangular plate and the horizontal clamping plate to move closer to or away from each other, so as to adjust the vertical clamping plates and the horizontal clamping plates according to the specifications of the workpiece, thereby effectively fixing the workpiece and facilitating the gluing operation of the gluing device.

DETAILED DESCRIPTION

[0019] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.

[0020] Example: A glue filling device based on PLC system control, such as Figure 1-Figure 3 As shown, it includes an organism 1, a human-machine controller 2, a gluing device 3, a discharge pipe 4, a feeding funnel 5, a material box 6, a vacuum device 7, a delivery pipe 8, a material pump 81, a transmission box 11 and an extrusion assembly. The gluing device 3 is movably provided on the top of the body 1. The gluing device 3 can slide along the front and rear directions of the top of the body 1. The gluing device 3 can also perform horizontal gluing operations along the left and right directions of the body 1. A human-machine controller 2 for controlling the gluing device 3 to perform gluing according to preset instructions is provided on one side of the body 1. A material box 6 is provided at the lower part of the body 1. A feeding funnel 5 is connected to one side of the material box 6. The feeding funnel 5 passes through a side wall of the body 1. A vacuum device 7 for exhausting the air in the material box 6 is provided on the material box 6. The vacuum device 7 sucks the air in the material box 6 to obtain the coating raw materials in a vacuum state, thereby preventing the presence of air in the coating from causing the coating to be coated. To prevent the defect of bubbles covering the workpiece, the discharge end of the material box 6 is connected to the transmission box 11 installed on the body 1 through the feed pipe 8. The feed pipe 8 is provided with a pumping pump 81 for sucking the raw materials in the material box 6 into the transmission box 11. When the pumping pump 81 is sucking, the paint in the vacuum state in the material box 6 is transported to the transmission box 11 through the feed pipe 8. The discharge end of the transmission box 11 is connected with the discharge pipe 4. The human-machine controller 2 is electrically connected to the gluing device 3, the vacuum device 7 and the feed pump 81. The human-machine controller 2 controls the gluing device 3, the vacuum device 7 and the feed pump 81 to perform corresponding operations according to preset instructions. An extrusion component is provided on the transmission box 11. The raw materials required for gluing in the transmission box 11 are transported to the gluing device 3 through the discharge pipe 4 for gluing after the extrusion action of the extrusion component. The bottom of the body 1 is provided with a universal wheel 18 for easy movement.

[0021] like Figure 3As shown, the extrusion assembly includes a cylinder 9 and a rubber pressure plate 10. The cylinder 9 is provided on the top of the transmission box 11, and the cylinder 9 is installed on the body 1 through a rod-shaped stand. The movable end of the piston rod of the cylinder 9 extends into the transmission box 11 and its end is connected to the rubber pressure plate 10. The outer diameter of the rubber pressure plate 10 is adapted to the inner diameter of the transmission box 11, and the rubber pressure plate 10 slides with the inner wall of the transmission box 11. Driven by the telescopic movement of the piston rod of the cylinder 9, the rubber pressure plate 10 moves up and down along the inner wall of the transmission box 11. A solenoid valve 12 is provided between the discharge end of the transmission box 11 and the discharge pipe 4. The solenoid valve 12 is electrically connected to the human-machine controller 2. The on-off of the inner cavity of the solenoid valve 12 is controlled by the human-machine controller 2, thereby controlling the flow of the paint in the transmission box 11 entering the discharge pipe 4 and controlling the on-off between the transmission box 11 and the inner cavity of the discharge pipe 4.

[0022] During use, the raw materials required for gluing are added into the material box 6 through the feed funnel 5, and the air in the material box 6 is extracted and discharged by the vacuum device 7, thereby avoiding air in the paint. The paint in the material box 6 is transported to the transmission box 11 through the feed pipe 8 by the suction action of the extraction pump 81; through the extension movement of the piston rod of the cylinder 9, the movable end of the piston rod of the cylinder 9 pushes the rubber pressure plate 10 to move from top to bottom along the inner wall of the transmission box 11, thereby squeezing the paint in the transmission box 11 into the discharge pipe 4, and the gluing device 3 applies the paint in the discharge pipe 4 to the workpiece, thereby realizing the coating operation of the workpiece.

[0023] like Figure 1 and Figure 4 As shown, it also includes a vertical clamping plate 13 and a telescopic rod 17. The telescopic rods 17 are symmetrically arranged on the left and right sides of the body 1. The movable ends of the telescopic rods 17 are connected to the "I"-shaped vertical clamping plates 13. The vertical clamping plates 13 slide in conjunction with the top plane of the body 1. The telescopic function of the telescopic rods 17 drives the vertical clamping plates 13 to move closer to or away from each other, thereby clamping and limiting the workpiece horizontally.

[0024] like Figure 4 As shown, it also includes a transverse clamping plate 14, a triangular plate 15 and a connecting screw 16. A connecting screw 16 is slidably provided on the vertical clamping plate 13. The end of the connecting screw 16 facing away from the vertical clamping plate 13 is connected to the triangular plate 15. The transverse clamping plate 14 is connected to the triangular plate 15. The distance between the two connecting screws 16 is adjusted by sliding, and the distance between the two transverse clamping plates 14 is adjusted, so that the workpiece is longitudinally clamped and limited.

[0025] The extension and contraction function of the telescopic rod 17 drives the vertical clamping plate 13 to slide horizontally along the top of the machine body 1, so that the distance between the two vertical clamping plates 13 can be adjusted according to the specifications of the workpiece. The sliding connecting screw 16 drives the triangular plate 15 and the horizontal clamping plate 14 to move closer to or away from each other along the vertical clamping plate 13, so that the workpiece can be clamped, which facilitates the gluing operation of the gluing device 3.

[0026] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
