Description

Technical Field

[0001] This utility model relates to the field of dispensing machine technology, specifically to a jet valve dispensing machine. Background Technology

[0002] A dispensing machine, also known as a glue applicator, glue dripper, glue applicator, or glue dispensing machine, is specifically designed for controlling fluids. This automated machine dispenses fluid onto the surface or interior of a product, enabling three-dimensional and four-dimensional path dispensing with precise positioning and control, preventing stringing, leakage, and dripping. A search revealed a Chinese patent with authorization announcement number CN209985703U that discloses a jet valve dispensing machine, relating to the field of dispensing machine technology. It includes a lower frame control cabinet with a base plate on top. The base plate has a pre-alignment guard at the top and includes a product adsorption section, a dispensing and CCD imaging section, a hot melt adhesive preheating section, a feeding section, a display, an X-axis for imaging, a human-machine interface (HMI), and a dispensing X-axis. The HMI is located above the operation control platform. Safety sensor light curtains are installed on both sides of the feeding section. The feeding section and product adsorption section are mounted on the product transfer Y-axis. A jet valve is mounted on the dispensing X-axis, and an imaging Z-axis is mounted on the imaging X-axis. Both the jet valve and the imaging Z-axis are electrically connected to servo motors. This invention solves the problem that the narrow edge width and small adhesive area of ​​the display screen make it impossible to complete the dispensing manually. The jet valve dispensing machine has high dispensing efficiency and high precision.

[0003] Currently, existing dispensing machines require preheating of the conveyed adhesive before spraying it. However, heat is easily lost during pipeline transportation, which can cause the sprayed adhesive to fail to meet the bonding standards. Furthermore, existing dispensing machines are susceptible to imbalances in transmission power during horizontal and vertical movement, resulting in inaccurate dispensing positions. Utility Model Content

[0004] To address the problems of existing dispensing machines easily lowering the adhesive temperature and lacking dispensing accuracy, this invention provides a jet valve dispensing machine.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A jet valve dispensing machine includes a worktable with a protective frame installed on the top side of the worktable. An X-axis mechanism is provided on the side of the worktable near the frame. A Y-axis mechanism is installed at the movable end of the X-axis mechanism, and a Z-axis mechanism is installed at the movable end of the Y-axis mechanism. A high-speed jet valve in a vertical orientation is installed at the movable end of the Z-axis mechanism. The high-speed jet valve includes a clamp and a heating chamber. The heating chamber is clamped and fixed inside the clamp. A feed port is provided on one side of the heating chamber, and a nozzle is connected to the feed port through the heating chamber. The nozzle is installed at the bottom of the heating chamber. The X-axis mechanism includes an X-axis motor and a pair of X-axis tracks. A synchronous belt drive assembly is driven to the output end of the X-axis motor. A transmission rod is driven to the X-axis motor through the synchronous belt drive assembly. X-axis conveyor belts driven by both ends of the transmission rods are movably connected inside the pair of X-axis tracks. An X-axis movable block is connected to one side of the X-axis conveyor belt and is slidably connected to the top surface of the X-axis track.

[0007] Furthermore, the Y-axis mechanism includes a Y-axis track and a Y-axis motor mounted on the top surface of the X-axis movable block. A Y-axis conveyor belt driven by the output end of the Y-axis motor is movably connected inside the Y-axis track. A Y-axis movable block is connected to one side of the Y-axis conveyor belt, and the Y-axis movable block is slidably connected to one side of the Y-axis track.

[0008] The beneficial effects of adopting the above-mentioned further solution are that the Y-axis track provides stable guidance for the Y-axis movable block, the Y-axis motor drives the Y-axis conveyor belt to rotate, and drives the Y-axis movable block to move precisely. It works in conjunction with the X-axis mechanism to achieve two-dimensional precise positioning in the plane, ensuring small dispensing position error. The Y-axis mechanism is installed on the top surface of the X-axis movable block to realize the linkage transmission of motion trajectory. The structure is compact and the transmission is efficient.

[0009] Furthermore, the Z-axis mechanism includes a fixed seat mounted on one side of the Y-axis movable block, a Z-axis slide rail mounted on one side of the fixed seat, a Z-axis slider slidably connected to one side of the Z-axis slide rail, and a mounting plate for fixing the fixture connected to one side of the Z-axis slider.

[0010] The beneficial effects of adopting the above-mentioned further solution are that the fixed base provides a stable mounting foundation for the Z-axis slide rail, and the Z-axis slider slides smoothly along the slide rail, ensuring the precise vertical movement of the high-speed jet valve and adapting to the dispensing height requirements of workpieces with different thicknesses; the mounting plate achieves a firm connection between the fixture and the Z-axis slider, avoiding dispensing deviation caused by the shaking of the jet valve during dispensing; the Z-axis mechanism works in conjunction with the X and Y axis mechanisms to construct a complete three-dimensional drive system, enabling the jet valve to accurately reach any dispensing position, improving the adaptability and dispensing accuracy of the dispensing machine, and meeting the operational needs of complex dispensing paths.

[0011] Furthermore, a retainer is installed on one side of the fixed base, and a cylinder is installed on the top surface of the retainer. The output end of the cylinder passes through the retainer and is connected to a push-pull block. One side of the push-pull block is connected to one side of the mounting plate.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the retainer provides stable support for the cylinder, and the cylinder drives the push-pull block to move the mounting plate and Z-axis slider up and down along the Z-axis slide rail, which can accurately control the lifting height of the spray valve and ensure consistent dispensing spacing.

[0013] Furthermore, a pressure boosting valve is connected to one side of the outer wall of the heating chamber, and an adjustment knob is provided on one side of the outer wall of the pressure boosting valve.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the pressure booster valve can adjust the pressure in the chamber, and the pressure can be precisely controlled by adjusting the knob, so that the glue can be sprayed out from the nozzle at a stable flow rate, avoiding uneven glue dispensing caused by pressure fluctuations.

[0015] Furthermore, the synchronous belt drive assembly includes a pair of synchronous pulleys and a synchronous belt. The output end of the X-axis motor and the outer wall of the transmission rod are respectively connected to the synchronous pulleys. The outer walls of the pair of synchronous pulleys are fitted with a synchronous belt and are connected by synchronous belt transmission.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the pair of synchronous pulleys and synchronous belts of the drive component cooperate to realize efficient transmission between the X-axis motor and the transmission rod. During the transmission process, the power loss is small and the transmission ratio is accurate, ensuring that the X-axis conveyor belts at both ends of the transmission rod operate synchronously and avoiding deviation when the X-axis movable block moves.

[0017] Furthermore, the X-axis track and the Y-axis track are respectively rotatably connected to fixed pulleys for tensioning the X-axis conveyor belt and the Y-axis conveyor belt, and the output end of the Y-axis motor and both ends of the transmission rod are connected to the fixed pulleys.

[0018] The beneficial effects of adopting the above-mentioned further solution are that the fixed pulleys in the X-axis and Y-axis tracks can tighten the X-axis conveyor belt and the Y-axis conveyor belt, avoiding transmission slippage or positioning errors caused by the slack of the conveyor belt, and ensuring transmission accuracy; the connection method between the fixed pulleys and the output end of the X-axis motor and both ends of the transmission rod makes the conveyor belt bear force evenly and run more smoothly, further improving the movement accuracy of the X and Y axis mechanisms.

[0019] Furthermore, the workbench has a glass tabletop embedded directly below the high-speed injection valve.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the glass tabletop is located directly below the high-speed jet valve, and the glass material is transparent, which makes it easy for operators to observe the dispensing process in real time, detect dispensing deviations in a timely manner and make adjustments, thereby improving the efficiency of dispensing quality control.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This type of jet valve dispensing machine, through the combined use of an X-axis mechanism and a high-speed jet valve, enables it to maintain the temperature of the adhesive in real time while providing high-precision dispensing. The frame on the top surface of the worktable forms a protective barrier to prevent adhesive splashing or interference from external impurities during dispensing. The X-axis, Y-axis, and Z-axis mechanisms form a three-axis linkage system, allowing the high-speed jet valve to move flexibly in three-dimensional space, adapting to the dispensing needs of workpieces of different sizes and shapes. The X-axis mechanism, driven by an X-axis motor, drives a synchronous belt drive assembly, causing the X-axis conveyor belts at both ends of the transmission rod to rotate synchronously. This allows the X-axis movable block to slide smoothly along the X-axis track, ensuring that both ends of the Y-axis mechanism receive equal transmission power synchronously, improving the precision of dispensing position adjustment. Furthermore, the clamps of the high-speed jet valve securely fix the heating chamber, which provides constant temperature heating for the adhesive. This ensures stable adhesive flow while reducing heat loss, ensuring the adhesive always maintains the required bonding standard. The connection design between the feed interface and the nozzle ensures smooth adhesive delivery and reduces the risk of clogging. Attached Figure Description
