Description

Technical Field

[0001] The utility model relates to the technical field of glue filling, in particular to quantitative filling equipment. Background Art

[0002] Epoxy glue is an adhesive based on epoxy resin, curing agent and filler. It has high bonding strength, chemical corrosion resistance, high temperature resistance and grease resistance. It can also achieve fast curing performance by adjusting internal components such as curing agent. In some industries, when using epoxy glue, most of them use fully automatic glue pouring machines to pour the mixed epoxy glue into the workpiece. Most of the existing fully automatic glue pouring machines are equipped with a three-axis machine that can automatically move three axes to control the position of the glue pouring equipment. Generally, the glue pouring equipment is metered inside. The metering pump is used to control the quantitative injection of the glue liquid. However, when the metering pump encounters a medium with high resistance during operation, it may cause the metering pump to operate at an inaccurate frequency, resulting in inaccurate quantitative injection of the metering pump. In addition, the metering pump has a relatively complex structure and is inconvenient to maintain. In addition, the working environment temperature has a greater impact on the epoxy glue. When the temperature is low, the viscosity of the glue increases, and wire drawing is likely to occur between the glue on the workpiece and the discharge head of the injection equipment. When the machine drives the injection equipment to move, the pulled glue threads are likely to float to the workpiece, workbench, etc., which is inconvenient to clean after curing, which is relatively inconvenient.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 5 In the embodiment of the utility model, a quantitative injection device includes a housing 100, a quantitative mechanism 300 is arranged inside the housing 100, and a discharge port 101 is opened at the center of the bottom end of the housing 100, an injection pipe 120 is fixedly connected to the bottom end of the housing 100, and the inside of the injection pipe 120 is connected to the inside of the discharge port 101, a mounting frame 110 is fixedly sleeved on the outer wall of the housing 100, and a closing mechanism 400 is arranged at the bottom opening of the injection pipe 120;

[0023] The quantitative mechanism 300 includes a tube body 310, and the top and bottom ends of the tube body 310 are fixedly connected to the top surface and the bottom surface of the shell 100 respectively. A cylinder 320 is fixedly connected to the top of the shell 100, and the movable end of the cylinder 320 passes through the top of the shell 100 and is fixedly sleeved with a piston plate 330. The piston plate 330 is slidably sleeved inside the tube body 310, and a plurality of extraction ports 311 are opened at the bottom end of the outer wall of the tube body 310. A connecting shell 340 is fixedly connected to the bottom end of the shell 100, and an electromagnet 341 is arranged inside the connecting shell 340. An annular magnet 350 is slidably sleeved on the outer wall of the tube body 310.

[0024] Specifically, the mounting frame 110 on the shell 100 is fixed to the three-axis machine platform, and then the user loads the glue into the shell 100. When glue filling is required, the quantitative mechanism 300 is started to quantify the amount of glue to be filled, and then the sealing mechanism 400 is started to open the injection tube 120, and then the quantitative mechanism 300 is started to output the quantitative glue to the injection tube 120 to complete the filling. When the quantitative mechanism 300 is used, the sealing mechanism 400 closes the opening of the injection tube 120, and then the electromagnet 341 is started to generate a magnetic force, and the magnetic force of the electromagnet 341 and the magnetic force of the annular magnet 350 repel each other, so that the annular magnet 350 is affected by the electromagnet 341 and moves upward, so that the multiple extraction ports 311 are opened, and then the user The operator starts the cylinder 320 to drive the piston plate 330 to move. Since the opening of the injection tube 120 is closed, negative pressure is generated when the piston plate 330 moves, and the glue liquid in the shell 100 is sucked into the interior of the tube body 310 from the multiple extraction ports 311. The amount of sucked glue liquid is controlled according to the movement distance of the piston plate 330, and then the electromagnet 341 is closed, so that the annular magnet 350 automatically presses down and closes the multiple extraction ports 311 due to its own weight, and then the sealing mechanism 400 is started to open the opening of the injection tube 120, and then the cylinder 320 is started again to press the piston plate 330 downward, so that the glue liquid in the tube body 310 is pressed by the piston plate 330 to flow out of the shell 100 through the discharge port 101 and the injection tube 120, thereby accurately and quantitatively injecting the glue liquid, and the structure is simple.

[0025] Embodiment 1

[0026] like Figure 1 As shown, in this embodiment, a connection hole 102 is opened at the top of the outer wall of the shell 100, and a material conveying pipe 200 is fixedly sleeved on the inner wall of the connection hole 102.

[0028] like Figure 2-3As shown, in this embodiment, a connecting ring 312 is fixedly sleeved on the outer wall of the tube body 310, a plurality of rebound springs 351 are fixedly connected to the top surface of the annular magnet 350, and the top ends of the plurality of rebound springs 351 are fixedly connected to the bottom surface of the connecting ring 312, a plurality of rubber tubes 352 are fixedly connected to the top surface of the annular magnet 350, and the top ends of the plurality of rubber tubes 352 are fixedly connected to the bottom surface of the connecting ring 312, the plurality of rubber tubes 352 correspond one-to-one to the plurality of rebound springs 351, and the plurality of rebound springs 351 are all located inside adjacent rubber tubes 352.

[0029] During specific implementation, when the electromagnet 341 is started and repelled from the annular magnet 350, the annular magnet 350 moves upward and squeezes the multiple rebound springs 351. Then, after the electromagnet 341 is turned off, the annular magnet 350 can be pushed and reset by the adjacent rebound springs 351, thereby facilitating the reset of the annular magnet 350. The rebound spring 351 is protected by a stretchable rubber tube 352 to isolate the rebound spring 351 from the glue and increase the service life of the rebound spring 351. The surface of the annular magnet 350 can also be attached with a material that does not affect the magnetic force, such as injected plastic, to cover the annular magnet 350 to isolate the annular magnet 350 from the glue and increase the service life of the annular magnet 350. The epoxy glue has good fluidity at thirty degrees, so that the glue temperature is not easy to affect the magnetic force of the magnet.

[0030] Embodiment 2

[0031] On the basis of the first embodiment, in order to achieve the effect that the closing mechanism 400 in the first embodiment can close the injection pipe 120 when the electromagnet 341 is started, and can open the injection pipe 120 when the electromagnet 341 is turned off.

[0032] like Figure 4-5As shown, in this embodiment, the closing mechanism 400 includes a cover plate 410, and the cover plate 410 is located below the injection pipe 120, both ends of the top surface of the cover plate 410 are fixedly connected to the rotating rods 420, and the tops of the two rotating rods 420 are provided with L-shaped rods 430, and one end of the long arm of the two L-shaped rods 430 is respectively rotatably connected to the tops of the two rotating rods 420, a supporting ring 440 is provided on the outer wall of the injection pipe 120, and a plurality of supporting rods are fixedly connected to the inner wall of the supporting ring 440, one end of the plurality of supporting rods is fixedly connected to the outer wall of the injection pipe 120, one end of the short arm of the two L-shaped rods 430 is fixedly connected to an iron sheet, and the two L-shaped rods 4 One side of the short arm 30 is fixedly connected with a return spring 444, one end of the two return springs 444 is fixedly connected to the top surface of the supporting ring 440, the two iron sheets are located below the connecting shell 340, the bottom surface of the supporting ring 440 is fixedly connected with two plate bodies 441, and the bottom end of one side of the two plate bodies 441 is fixedly connected with an ejection spring 442, one end of the two ejection springs 442 respectively contacts one side of the two rotating rods 420, the bottom surface of the supporting ring 440 is fixedly connected with two limit plates 443, and one side of the two limit plates 443 respectively contacts one side of the two L-shaped rods 430, and the length of the plate body 441 is greater than the length of the limit plate 443.

[0033] In a specific implementation, when the electromagnet 341 is started, the magnetic force of the electromagnet 341 and the annular magnet 350 repel each other, causing the annular magnet 350 to move upward, and the magnetic force generated by the electromagnet 341 can attract the two iron sheets, thereby driving the two L-shaped rods 430 to pull the adjacent rotating rods 420 and the cover plate 410 upward, so that the top ends of the two rotating rods 420 collide with the adjacent limiting plates 443 to keep the two rotating rods 420 vertical, so that the cover plate 410 covers the opening of the injection pipe 120 for sealing, and then when the electromagnet 341 is turned off, the annular magnet 350 is pulled by the adjacent rebound spring 351 drives the multiple extraction ports 311 to be pressed down and closed. At the same time, the two L-shaped rods 430 are pulled and reset by the adjacent reset springs 444, so that the two L-shaped rods 430 drive the adjacent rotating rods 420 and the cover plate 410 to move downward synchronously, so that the cover plate 410 is located below the injection pipe 120, and the two rotating rods 420 are separated from the adjacent limiting plates 443, and then the rotating rod 420 is driven by the two ejection springs 442 to rotate partially, so that the cover plate 410 is driven by the two rotating rods 420 to move to the side of the injection pipe 120, thereby not easily blocking the injection pipe 120 from opening and discharging glue.

[0034] In the present invention, after the glue is filled, if the glue and the glue inside the injection tube 120 produce wire drawing, the electromagnet 341 is started again to adsorb the two L-shaped rods 430 and move them upward, so that the two rotating rods 420 are rotated to the bottom of the injection tube 120 first, and the glue threads that may be produced are cut. Then, as the cover plate 410 is reset, it can block the injection tube 120, thereby avoiding the problem of excessive glue wire drawing and the glue threads adhering to the workbench and other places that are inconvenient to clean.

[0035] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
