Description

Technical Field

[0001] This invention relates to a dispensing machine. Background Technology

[0002] Aluminum head assemblies are used in vehicles and other similar applications, such as... Figure 1 It consists of an aluminum sleeve 1 and a copper tube 2. The aluminum sleeve is screwed onto the head of the copper tube. The installation method is as follows: apply glue to the aluminum sleeve, and then align the head of the copper tube with the aluminum sleeve and screw it in to complete the assembly.

[0003] The main disadvantages of manual assembly include low production efficiency, high labor intensity, poor consistency, difficulty in quality control, and high cost.

[0004] The assembly process is easily affected by the skill level and operating habits of workers, making it difficult to ensure the consistency of each component and prone to quality problems. Furthermore, it is difficult to conduct rigorous quality control and testing on each component, potentially leading to quality issues that are difficult to detect and resolve in a timely manner.

[0005] Therefore, automated assembly equipment may be a better choice for mass production and products requiring high quality. Summary of the Invention

[0006] To overcome the shortcomings of current manual assembly of aluminum-clad copper tube assemblies where quality control is difficult, this invention provides a dispensing assembly machine.

The tail end of the aluminum sleeve feeding conveyor belt is provided with an aluminum sleeve transfer position. The aluminum sleeve transfer position includes a transfer rod that can accommodate one aluminum sleeve. The transfer rod is driven by a transfer rod driving device to transport the aluminum sleeve from the tail end of the aluminum sleeve feeding conveyor belt to the edge of the worktable. The material transfer mechanism is located on one side of the workbench and includes a power-driven material transfer plate that pushes the aluminum sleeves onto the workbench forward in sequence. The workbench includes a screwing station, and the screwing mechanism is located on the screwing station; the screwing mechanism includes a copper tube screwing device and an aluminum sleeve clamping device, and the aluminum sleeve clamping device clamps the aluminum sleeve on the screwing station. The copper tube feeding mechanism includes a copper tube feeding conveyor belt, and a power-driven copper tube transfer robot is provided on one side of the copper tube feeding conveyor belt. The copper tube transfer robot transfers the copper tube to the copper tube screwing device. The copper tube screwing device includes a copper tube clamping claw plate mounted on a movable table. The upper end of the copper tube clamping claw plate is connected to a screwing motor that drives the copper tube clamping claw plate to rotate. The movable table is driven by the movable table driving unit to move up and down. The dispensing mechanism includes a dispensing gun located on one side of the screwing mechanism that can extend or retract, and the dispensing gun can extend forward to be aligned with the aluminum sleeve. The unloading mechanism includes an unloading channel, and a unloading robot arm is provided on one side of the unloading channel to move the workpiece from the worktable to the unloading platform.

[0008] The copper tube screwing device is preferably designed to include a stand with a vertically mounted guide rail. The movable platform slides on the guide rail, and a screwing stroke cylinder is provided at the rear end of the movable platform. The piston end of the screwing stroke cylinder is provided with a baffle. When the copper tube encounters the aluminum sleeve while the movable platform is descending, the baffle is blocked by the stand and cannot descend. The baffle can retract and has a retraction stroke, the length of which is equal to the stroke length of the aluminum sleeve screwing onto the copper tube.

[0009] In a preferred embodiment, the movable stage drive unit is a movable stage drive cylinder.

[0010] The structure of the movable table drive unit is optimized by including a central locking block and a top locking block on the drive shaft. A connecting block with a connection hole is provided at the connection point between the movable table and the drive shaft. The drive shaft passes through the connecting block, with the central locking block at the upper end and the top locking block at the lower end. A buffer spring is provided between the connecting block and the top locking block. This design allows the movable table to have two vertical movement modes: rapid movement and slow rotation relying on its own weight.

[0011] The aluminum sleeve clamping device is further refined and optimized. The aluminum sleeve clamping device includes an aluminum sleeve clamping device lifting cylinder. The piston end of the aluminum sleeve clamping device lifting cylinder is equipped with an aluminum sleeve clamping device. The aluminum sleeve clamping device is a clamping claw plate. The worktable is provided with a through groove at the turning position. The jaws of the clamping claw plate pass through the through groove to clamp the aluminum sleeve.

[0012] The material transfer mechanism is further refined and optimized. The material transfer mechanism includes a material transfer horizontal guide rail, on which a first material transfer platform driven by a power is movably mounted. A material transfer vertical guide rail is mounted on the first material transfer platform, and a second material transfer platform driven by a power is movably mounted on the material transfer vertical guide rail.

[0017] In this invention, aluminum sleeves and copper tubes are placed on a feeding conveyor belt. The aluminum sleeves, propelled by the conveyor belt, reach the transfer rod at the aluminum sleeve transfer position and are then individually moved forward by the transfer rod to the worktable. On the worktable, the aluminum sleeves are moved one by one by the transfer plate to the turning station. The aluminum sleeves are gripped by the clamping claws, and the glue gun of the glue dispensing mechanism dispenses glue into the aluminum sleeves. Simultaneously, the copper tubes, passing through the feeding conveyor belt, are gripped by the copper tube transfer robot and moved to the turning station. There, they are gripped by the copper tube clamping claws, and the moving table drive unit drives the copper tubes downwards until the baffle is blocked by the upright frame, meaning the head of the copper tube just touches the aluminum sleeve. Then, the turning stroke cylinder retracts, and under the influence of gravity and the rotation of the turning motor, the copper tube is turned into the aluminum sleeve. After turning, the unloading robot grips the workpiece, the clamping claws release, and the unloading robot moves the workpiece to the unloading channel.

[0018] The beneficial effects of this invention are as follows: 1. Fully automatic equipment can achieve high-speed and continuous production, greatly improving production efficiency, saving labor costs, and reducing production costs in the long run. 2. Fully automatic equipment operates stably, maintaining consistency in the production process, reducing variations caused by human operation, and enabling precise dispensing and twisting assembly, ensuring stable product quality.
