Description

Technical Field

[0001] This invention relates to the field of dispensing equipment technology, and in particular to a dispensing mechanism and dispensing equipment for two-component adhesives. Background Technology

[0002] Two-component dispensing machines, also known as AB dispensing machines, are specialized equipment for dispensing two-component materials. They enable the mixing of two adhesives in a specific ratio before application. Particularly in fields such as automotive, military, aerospace, and medical devices, these dispensing machines feature more refined valve designs, simpler flow channels, and employ high-precision nozzles and micro-flow control technology to ensure the accuracy and consistency of micro-dispensing. For example, in automotive projects, the dispensing ratio of thermal conductive gel is typically 1:1, requiring the deviation between the A and B adhesive ratios to not exceed 5%, further increasing the demands on dispensing precision.

[0003] Current dispensing equipment and dispensing valve assemblies, while using plunger valves to dispense two components of adhesive and employing metering cylinders to measure components A and B, can improve the accuracy of dispensing volume control. However, the adhesive in the metering cylinder of such dispensing equipment must be pushed in from the feed hopper. In traditional dispensing equipment, the feeding of the feed hopper and the dispensing of the metering cylinder are controlled separately or without correlation. When the adhesive in the metering cylinder is low or nearly empty, the pressure detector inside the metering cylinder cannot detect the total amount of adhesive remaining. This results in the inability to timely feed the metering cylinder, leading to poor stability in the dispensing volume. Summary of the Invention

[0004] The purpose of this invention is to address the problem in existing dispensing equipment where the feeding of the feed hopper and the dispensing of the metering cylinder are controlled separately or without coordination. When the amount of adhesive in the metering cylinder is low or nearly empty, the pressure detector inside the metering cylinder cannot detect the total amount of adhesive remaining, resulting in inconsistent adhesive dispensing volume due to the inability to timely feed the metering cylinder. This invention provides a dispensing mechanism and equipment for two-component adhesives.

[0005] To achieve the objectives of this invention, the following solutions are provided:

[0006] A glue supply mechanism for two-component adhesives includes: a glue infeed assembly, a fixed frame, a piston pushing component, a metering cylinder, a drive motor, a transmission shaft, a slider, and a dispensing assembly;

[0007] The glue-feeding assembly is connected to the upper end of the piston-pushing component via a first connecting pipe section; the piston-pushing component has a channel, and the lower end of the piston-pushing component is connected to the metering cylinder and communicates with the metering cylinder through the channel; the drive motor is fixed to the fixing frame; the upper end of the transmission shaft is driven and connected to the drive motor, and the transmission shaft is axially connected to the slider, which can drive the slider to move axially; the piston-pushing component is fixed to the slider and can move axially with the slider;

[0008] The first connecting pipe section is equipped with a glue inlet switch valve; the glue inlet switch valve is electrically connected to the drive motor and can be opened or closed in accordance with the limit threshold of the drive motor; the metering cylinder is connected to the dispensing assembly; the dispensing assembly is used to dispense glue onto the product.

[0009] The glue supply mechanism for two-component adhesives of the present invention is connected to the upper end of the piston pusher via a first connecting pipe section, enabling the glue to be pushed into the piston pusher. By providing a drive motor, the transmission shaft can be driven to move or rotate axially, which in turn drives the slider to move axially, thereby driving the piston pusher to move axially, thus pushing the glue in the metering cylinder to the dispensing assembly. Furthermore, by providing a glue inlet switch valve with an electrical signal connected to the drive motor, the drive motor moves the piston pusher axially downward to the maximum position according to a limit threshold. At the low position, an electrical signal is transmitted to the glue inlet switch valve to open the ball valve, controlling the glue material in the glue inlet assembly to enter the piston pusher. When the drive motor moves the piston pusher axially to the highest position according to the limit threshold, an electrical signal is transmitted to the switch ball valve to close the ball valve, controlling the glue inlet assembly to pause feeding. This synchronizes the filling or pausing of filling with the extension and retraction limit threshold of the piston pusher, improving the synchronization of the filling in the metering cylinder, reducing the impact of glue dispensing volume when there is little or no glue in the metering cylinder, improving the stability of glue supply, and improving the dispensing quality of the product.

[0010] Preferably, in the glue supply mechanism for two-component adhesives of the present invention, the glue inlet switch valve includes: a ball valve, a fixing member, a support column, a rotary cylinder, and a rotary shaft; the axial ends of the ball valve are respectively connected to the piston pushing member and the glue inlet assembly; the fixing member is fixedly connected externally to the ball valve; the rotary cylinder and the fixing member are respectively fixedly connected to both ends of the support column; the rotary cylinder is driven to the valve core of the ball valve through the rotary shaft.

[0011] As a preferred embodiment of the present invention, by setting the switching valve to a ball valve including the above structure, the rotary cylinder can quickly drive the valve core of the ball valve to rotate to open or close the ball valve when it receives an electrical signal of the limit threshold, thereby further improving the synchronization of the glue feeding to the piston pushing part.

[0012] Preferably, in the glue supply mechanism for two-component adhesives of the present invention, one axial end of the ball valve is connected to the piston pusher via an adapter assembly; the adapter assembly includes: an adapter and a fastener; the adapter and the piston pusher are axially abutted, and the fastener is radially tightened to the outside of the adapter and the piston pusher; an axially fitted seal is provided between the adapter and the piston pusher.

[0013] As a preferred embodiment of the present invention, by setting the adapter and the seal, the piston pusher that bears the force of axial piston movement can have stronger tensile crack resistance, reduce the risk of rubber leakage at the joint caused by the piston pusher moving axially with the slider, and further improve the reliability of the feeding mechanism.

[0014] Preferably, in the glue supply mechanism for two-component adhesives of the present invention, the piston pusher includes a connected axial extension section and an oblique extension section; the axial extension section is close to the metering cylinder and partially located inside the metering cylinder; the oblique extension section is radially inclined, and a section away from the axial extension section is connected to the glue inlet switch valve.

[0015] As a preferred embodiment of the present invention, by setting the radially inclined oblique extension section, not only is an installation position provided for the glue inlet switch valve and the glue inlet assembly, allowing the glue inlet assembly to enter the piston push rod axially, but also, in the case of an equipment installation layout where the axial direction of the feeding mechanism is parallel to the vertical, the pressure and gravity of the glue during the feeding process are aligned, reducing the flow pressure error caused by the inconsistency between the glue flow direction and the gravity direction, further improving the accuracy of the feeding pressure control and the dispensing precision; and, by setting the radially inclined section, compared to the traditional glue inlet assembly being laterally connected to the piston rod, the resistance of the glue from the glue inlet assembly to the piston push part can be reduced, reducing the influence of external resistance on the dispensing pressure, thereby further improving the accuracy of the dispensing pressure control and the dispensing precision.

[0016] Preferably, in the adhesive supply mechanism for two-component adhesives of the present invention, the radial inclination angle of the inclined extension section is 45°.

[0017] As a preferred embodiment of the present invention, by setting an inclination angle, the matching degree between the position setting of the glue inlet switch valve and the glue inlet assembly and the glue flow direction can be further improved, the mechanical matching of the mechanism can be further improved, the failure rate of the equipment can be reduced, and the reliability can be improved.

[0018] Preferably, in the glue supply mechanism for two-component adhesives of the present invention, the slider is fixed to the outside of the connection between the axial extension section and the oblique extension section.

[0019] As a preferred embodiment of the present invention, by specifically setting the fixed position of the slider, the inclined extension section can bear the abutting force of the slider's axial movement, further reducing the possibility of the piston pushing component slipping off the slider and improving the reliability of the feeding mechanism.

[0020] Preferably, in the glue supply mechanism for two-component adhesives of the present invention, the fixed frame is provided with a slide rail and a limiting bracket; the slider is axially slidably connected to the slide rail; the transmission shaft is fixed to the upper end of the limiting bracket by a bearing; and the piston pushing component is fixed to the lower end of the limiting bracket by a bearing.

[0021] As a preferred embodiment of the present invention, by setting the slide rail and the limiting bracket, the possibility of loosening or misalignment during the axial movement of the piston pushing component is reduced, thereby further improving the stability of glue supply and improving the accuracy of glue dispensing.

[0022] Preferably, the glue supply mechanism for two-component adhesives according to the present invention further includes a calibration component; the calibration component is used to calibrate the position of the glue needle of the dispensing component.

[0023] As a preferred embodiment of the present invention, the position of the glue needle of the dispensing assembly can be verified by the verification component, which can further improve the accuracy of dispensing.

[0024] To achieve the objective of this invention, the solution is as follows:

[0025] A dispensing device includes a transport component, a first conveying mechanism, a platform, and a dispensing mechanism for a two-component adhesive. The dispensing mechanism is fixed to the transport component. The transport component is fixed above the platform via a gantry bracket. The transport component is used to transport the dispensing mechanism along the X, Y, and Z axes. The parallel guide rail of the first conveying mechanism is fixed to the platform surface via an adjusting rod and is located below the transport component. The adjusting rod is perpendicular to the long side of the parallel guide rail. The first conveying mechanism is used to transport the dispensing product.

[0026] The dispensing equipment of this invention, based on a more precise and stable glue supply mechanism, combined with the carrier component and the first conveying mechanism, can more accurately control the positioning of the dispensing end and the dispensing product, improving the accuracy of the product dispensing position and the dispensing quality. Furthermore, by setting the parallel guide rails of the first conveying mechanism to the platform surface via adjusting rods, and if multiple parallel guide rails are used, the spacing between them can be adjusted along the adjusting rods, thus adapting to all production lines. This allows the first conveying mechanism of the dispensing equipment to be adapted and connected to all production lines, forming a non-standard dispensing equipment, thereby improving efficiency. This dispensing equipment is versatile; moreover, the first conveying mechanism is located above the platform and below the transport component, which is fixed to the platform by a gantry bracket, thereby providing a through-type working space for the production line products. This facilitates the smooth transport of dispensing products from the production line to the accurate dispensing position of the dispensing equipment and out of the dispensing equipment. It seamlessly integrates into the company's existing automated production line without the need for additional loading and unloading station conversion time, achieving efficient connection with upstream and downstream processes. It breaks the production breakpoints of traditional offline dispensing equipment, significantly shortens the overall product production cycle, and improves the continuity and efficiency of dispensing operations.

[0027] Preferably, the dispensing equipment of the present invention further includes: a second conveying mechanism; the second conveying mechanism is disposed below the platform surface and is vertically parallel to the first conveying mechanism; the conveying direction of the second conveying mechanism is opposite to the conveying direction of the first conveying mechanism.

[0028] As a preferred embodiment of the present invention, by setting up a second conveying mechanism with the conveying direction of the second conveying mechanism being opposite to that of the first conveying mechanism, and by connecting the first conveying mechanism and the second conveying mechanism to the production line respectively, a cycle can be formed to deliver finished dispensing products and deliver products to be dispensed. This not only saves production and transportation space, but also improves the stability of dispensing product transportation, further reduces the number of products with dispensing errors or missing dispensing, and improves dispensing quality.

[0029] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0030] 1. The glue supply mechanism for two-component adhesives, by setting a glue inlet switch valve and connecting an electrical signal to a drive motor, when the drive motor moves the piston pusher axially downward to the lowest position according to the limit threshold, the electrical signal is transmitted to the glue inlet switch valve to open the ball valve, controlling the glue inlet assembly to enter the piston pusher; when the drive motor moves the piston pusher axially upward to the highest position according to the limit threshold, the electrical signal is transmitted to the switch ball valve to close the ball valve, controlling the glue inlet assembly to pause feeding, thereby synchronizing the filling or pausing filling with the extension and retraction limit threshold of the piston pusher, improving the synchronization of the filling in the metering cylinder, reducing the impact of glue dispensing volume when the glue in the metering cylinder is low or at the bottom, improving the stability of glue supply, and improving the dispensing quality of the product;

[0031] 2. The dispensing equipment, based on the more precise and stable glue supply mechanism, combined with the setting of the carrier component and the first conveying mechanism, can more accurately control the positioning of the dispensing end and the dispensing product, improve the accuracy of the product dispensing position, and improve the dispensing quality; by adjusting the spacing of multiple parallel guide rails along the adjusting rod, it can be adapted to all production lines, and the first conveying mechanism of the dispensing equipment can be adapted and connected to all production lines to form a non-standard dispensing equipment, thereby improving the universality of the dispensing equipment;

[0032] 3. The dispensing equipment has a first conveying mechanism located above the platform and below the carrying components, which provides a through-type working space for the production line products. This facilitates the smooth transport of the dispensing products from the production line to the accurate dispensing position of the dispensing equipment and out of the dispensing equipment, thereby improving the continuity and efficiency of the dispensing operation.

[0046] The metering cylinder 4 of the present invention is connected to the dispensing assembly 8. Through multiple sections of mixing tube, the uniformity and proportion consistency of the two adhesives can be improved. By setting the glue inlet switch valve 10 and pressure sensor 41, the damage to the cylinder itself when the cylinder retracts is reduced. When the amount of residual glue in the adhesive has reached the bottom, glue waste is reduced and the problem of incomplete glue discharge is solved.

[0047] The metering cylinder 4 of the present invention is connected to the dispensing assembly 8, as shown in the reference. Figure 1 and Figure 2 As shown, the metering cylinder 4 is connected to the glue needle 81 of the dispensing assembly 8 via a connecting pipe. A dispensing valve 82 is located on the upper part of the glue needle 81. The dispensing valve 82 is connected to the control system via an electrical signal. The dispensing valve 82 can be a conventional dispensing valve 82, capable of controlling the glue dispensing from the glue needle 81 to stop dispensing. Specifically, the pipe section connecting the metering cylinder 4 to the glue needle 81 is equipped with a pressure sensor 41. The probe of the pressure sensor 41 is sealed and inserted into the flow channel of the glue, enabling it to detect the liquid pressure of the glue dispensing from the metering cylinder 4.

It should be noted that the valve core of the present invention is understood to be a component that is usually installed inside the ball valve 101 and can open or close the valve body passage 31 by axial rotation.

[0049] Specifically, one axial end of the ball valve 101 is connected to the piston pusher 3 via an adapter assembly 106; the adapter assembly 106 includes an adapter 1061 and a fastener 1062; the adapter 1061 and the piston pusher 3 are axially abutted, and the fastener 1062 is radially tightened to the outside of the adapter 1061 and the piston pusher 3; an axially fitted seal 1063 is provided between the adapter 1061 and the piston pusher 3.

More specifically, the radial inclination angle of the oblique extension section 33 is 45°. (Reference) Figure 1 and Figure 2 As shown, the slider 7 is fixed to the outside of the connection between the axial extension section 32 and the oblique extension section 33.

[0051] Specifically, the axial transmission connection between the transmission shaft 6 and the slider 7 of the present invention can be a lead screw connection. The drive motor 5 drives the transmission shaft 6 to rotate, and the slider 7 is connected to the transmission shaft 6 through a bearing lead screw. The rotation of the transmission shaft 6 drives the slider 7 to move axially, thereby realizing the axial transmission connection between the slider 7 and the transmission shaft 6.

[0052] The glue supply method of this invention is as follows: The glue inlet switch valve 10 is closed according to the limit threshold of the drive motor 5. The piston pusher 3 moves axially towards the dispensing assembly 8, pushing the glue in the piston push rod and the metering cylinder 4 to supply glue and mix to the dispensing assembly 8.
