Description

Technical Field

[0001] The invention relates to the technical field of glue injection devices, in particular to an annular sixteen-cylinder piston type single-component cylinder metering glue injection device. Background Art

[0002] With the continuous development of electronic technology, motors, mobile phones, tablet computers, auto parts, etc. are pursuing lightweight products while ensuring product performance. Traditional processes can no longer meet the current requirements for some electronic sealing, thermal conductivity, electrical conductivity, etc. of products. Dispensing machines can improve product performance requirements while ensuring the requirements.

[0003] At present, most dispensing machines use single-head or multi-head inline dispensing, and multi-head inline dispensing is mostly 4-6 heads. Due to the process of the dispensing machine, some process flows must be completed during dispensing. This process cannot be saved in any way, which leads to extended dispensing time. Multi-head dispensing can solve the production requirements of some companies. In the existing technology, for some large motor manufacturers with a daily output of tens of thousands, the current 4-6-head dispensing equipment has limited output and cannot achieve output while ensuring product performance. Therefore, it cannot meet the company's requirements. Moreover, most of the current multi-head dispensing machines use screw valves or inline piston metering valves, which have high cost and low output for motor stator dispensing, affecting product output. Moreover, the current multi-head design requires shutdown for maintenance if any head has problems, affecting the company's production schedule. Summary of the Invention

The glue presses the piston rod 13 to make it rise upward inside the metering cylinder 14. When it reaches the sensing position, the glue feeding stops, and then passes through the fourth rotation drive module 702, the third pulley module 704 and the second pulley module 7 03 drives the two second lead screws 701 to rotate synchronously, and then drives the metering pressure block 6 to slide downward, and synchronously squeezes each piston rod 13 downward, so that the glue inside the metering cylinder 14 enters the inside of the one-way valve 15, the connecting head 16 and the needle 12 along the glue outlet channel 8014, and the 16 needles 12 dispense glue to multiple parts of the workpiece at the same time. The second rotary drive module 302 drives the rotary drive block 301 to rotate, and the rotary drive block 301 drives the workpiece positioning tooling 204 to rotate, adjusts the position of the workpiece, and dispenses glue to different positions of the workpiece. At the same time, another workpiece positioning tooling 204 to be dispensed glue is placed on the other end of the placement plate 203 to improve work efficiency.
