[0001] This utility model relates to the technical field of liquid filling devices, specifically an automatic adhesive filling device. Background Technology

[0002] In fields such as electronic assembly and precision instrument manufacturing, it is often necessary to precisely fill adhesives (such as epoxy resin and silicone) into tiny or specific cavities. Currently, common automatic adhesive filling devices typically use independent two-position three-way valves or two linked on / off valves to control the flow and direction of the fluid.

[0003] In the prior art, after the valve core and valve seat are closed, a small amount of adhesive will remain in the flow channel. The instantaneous opening and closing of the valve core will cause a sharp change in the pressure in the pipeline, resulting in adhesive leakage. Utility Model Content

A sealing plate is rotatably connected to the outlet of the delivery tube, and a sealing ball is vertically slidably connected inside the injection tube. During the downward movement of the sealing ball, there is a sealing position for sealing the delivery tube. During the downward movement of the sealing ball, the transmission assembly drives the sealing plate to rotate and seal the outlet of the delivery tube.

[0006] Furthermore, a rotating shaft is horizontally arranged inside the infusion tube, and the sealing plate is rotatably sleeved on the rotating shaft. A contact block is provided on one side of the sealing plate, and a connecting rod is vertically arranged on the top of the sealing ball. A pushing rod is provided on the connecting rod.

[0008] Furthermore, the base is provided with a positioning mechanism, which is used to position the filling container to be filled.

[0009] Furthermore, the positioning mechanism includes a fixed frame, a movable plate slidably connected to the fixed frame, and a positioning plate slidably connected to the movable plate. The positioning plate is L-shaped, and the moving direction of the positioning plate is perpendicular to the moving direction of the movable plate.

[0010] Furthermore, the fixed frame has a first through hole horizontally, the movable plate is L-shaped, a first bolt is screwed onto the movable plate, the first bolt passes through the first through hole and abuts against the fixed frame, the positioning plate has a second through hole horizontally, a second bolt is screwed onto the positioning plate, the second bolt abuts against the movable plate through the second through hole.

Detailed Implementation

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] Please see Figure 1-4 The present invention provides a technical solution: an automatic adhesive filling device, comprising a base 1 and a transmission assembly, wherein a filling mechanism is provided on the base 1, the filling mechanism comprising an injection pipe 4, an infusion pipe 5 horizontally provided on one side of the injection pipe 4, an outlet pipe 18 provided at the bottom of the injection pipe 4, a sealing plate 15 rotatably connected to the outlet of the infusion pipe 5, and a sealing ball 12 vertically slidably connected inside the injection pipe 4, wherein the sealing ball 12 has a sealing position for sealing the outlet pipe 18 during the downward movement of the sealing ball 12, and the sealing plate 15 is driven to rotate by the transmission assembly to seal the outlet of the infusion pipe 5 during the downward movement of the sealing ball 12. Specifically, the inner diameter of the outlet pipe 18 is smaller than the diameter of the sealing ball 12.

[0021] In this embodiment, a rotating shaft 16 is horizontally arranged inside the infusion tube 5. The sealing plate 15 is rotatably sleeved on the rotating shaft 16. An abutment block 17 is provided on one side of the sealing plate 15. A connecting rod 13 is vertically arranged on the top of the sealing ball 12. A push rod 14 is provided on the connecting rod 13. During the upward movement of the sealing ball 12, the push rod 14 abuts against the abutment block 17. Specifically, a controller 2 is provided on the base 1, and a cylinder 3 is provided on the injection tube 4. The cylinder 3 is connected to the controller 2. The controller 2 controls the cylinder 3 to drive the connecting rod 13 to move upward, releasing the sealing ball 12 from blocking the outlet tube 18. Then, the connecting rod 13 drives the push rod 14 to move upward and abut against the abutment block 17. The abutment block 17 is subjected to force, causing the baffle to rotate around the axis of the rotating shaft 16, thereby opening the opening of the infusion tube 5, and then the filling operation is performed.

[0022] In this embodiment, the transmission component includes a torsion spring, which is disposed between the rotating shaft 16 and the sealing plate 15. The torsion spring is used to drive the sealing plate 15 to rotate and seal the outlet of the infusion tube 5. Specifically, after filling is completed, the connecting rod 13 drives the sealing ball 12 to move down, and the pushing rod 14 no longer contacts the abutment block 17. The sealing plate 15 is reset by the torsion spring, first sealing the infusion tube 5 and immediately cutting off the supply of adhesive. Then the sealing ball 12 continues to move down to seal the outlet tube 18. This fundamentally eliminates the pressure shock of the pipeline system during the closing process and ensures that the pressure in the injection tube 4 has been released when the outlet is sealed, thereby completely eliminating the leakage phenomenon after closing. The dual sealing mechanism of the sealing plate 15 and the sealing ball 12 is adopted, which greatly improves the sealing reliability and service life of the device.

[0023] In this embodiment, a positioning mechanism is provided on the base 1. The positioning mechanism is used to position the filling container to be filled. The positioning mechanism includes a fixed frame 7, a movable plate 9 is slidably connected to the fixed frame 7, and a positioning plate 11 is slidably connected to the movable plate 9. The positioning plate 11 is L-shaped, and the moving direction of the positioning plate 11 is perpendicular to the moving direction of the movable plate 9. A first through hole 8 is horizontally opened on the fixed frame 7. The movable plate 9 is L-shaped and a first bolt is screwed onto the movable plate 9. The first bolt passes through the first through hole 8 and abuts against the fixed frame 7. A second through hole 10 is horizontally opened on the positioning plate 11. A second bolt is screwed onto the positioning plate 11. The second bolt abuts against the movable plate 9 through the second through hole 10. Specifically, the first bolt and the second bolt generate sufficiently large friction with the fixed frame 7 and the movable plate 9 respectively, which can adjust the position of the positioning plate 11. According to the different specifications of the container, the opening of the container can be aligned with the liquid outlet pipe 18.

[0024] In this embodiment, a liquid storage tank 6 is vertically raised and lowered on the base 1. A hydraulic cylinder is installed inside the base 1. The output end of the hydraulic cylinder is fixedly connected to the bottom of the liquid storage tank 6. A water pump is installed on the liquid storage tank 6. The infusion pipe 5 is connected to the liquid storage tank 6 through the water pump. Specifically, when the container is placed on the base 1, the hydraulic cylinder drives the outlet pipe 18 to move down through the liquid storage tank 6, so that the outlet of the outlet pipe 18 corresponds to the opening of the container, so that the adhesive is accurately injected into the container. The hydraulic cylinder is connected to the controller 2.

[0025] It should be noted that the specific models and specifications of the hydraulic cylinder, air cylinder 3, water pump and controller 2 need to be selected and determined according to the actual specifications of the device, so their control methods and wiring layout will not be described in detail.

[0026] Working principle: The automatic adhesive filling device first abuts the container against the positioning plate 11, so that the opening of the container faces the outlet pipe 18. Then, the controller 2 controls the cylinder 3 to drive the connecting rod 13 upward, releasing the sealing ball 12 from blocking the outlet pipe 18. Then, the connecting rod 13 drives the pushing rod 14 upward to fit against the abutment block 17. The abutment block 17 is subjected to force, causing the baffle to rotate around the axis of the rotating shaft 16, thereby opening the opening of the infusion pipe 5. Then, the filling operation is performed. After the filling is completed, the connecting rod 13 drives the sealing ball 12 downward, pushing... The moving rod 14 no longer contacts the abutment block 17, and the sealing plate 15 is reset by the torsion spring. First, the infusion tube 5 is sealed, and the supply of adhesive is immediately cut off. Then, the sealing ball 12 continues to move down to seal the outlet tube 18. This fundamentally eliminates the pressure shock of the pipeline system during the closing process and ensures that the pressure in the injection tube 4 has been released when the outlet is sealed, thus completely eliminating the leakage phenomenon after closing. The dual sealing mechanism of sealing plate 15 and sealing ball 12 greatly improves the sealing reliability and service life of the device.

[0027] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
