Problems solved by technology

[0003] For some products, it is difficult to complete the dispensing task with ordinary straight needles when dispensing the inner groove, so a curved needle is required to extend the needle into the groove for dispensing; for dispensing inside the groove And the groove is ring-shaped, even if a curved needle is used, it is still difficult to conveniently complete the 360° dispensing of the inside of the groove

Abstract

The invention discloses a bent needle dispensing method. The bent needle dispensing method comprises the following steps of 1, moving a bent needle to a side of a product to be dispensed, 2, moving a rotation positioning device to a first rounded corner along a straight line and aligning the bent needle to the first rounded corner, 3, driving the bent needle to rotate by 90 degrees by the rotation positioning device and carrying out dispensing at the first rounded corner, 4, after dispensing at the first rounded corner, driving the rotation positioning device to move to a second rounded corner along a straight line and aligning the bent needle to the second rounded corner, 5, driving the bent needle to rotate by 90 degrees by the rotation positioning device and carrying out dispensing at the second rounded corner, 6, repeating the above steps until all rounded corners are subjected to dispensing, and 7, moving the bent needle away from the dispensing surface and carrying out above steps on the next product to be dispensed. Through driving the bent needle to rotate by the rotation positioning device and orderly carrying out dispensing, the bent needle dispensing method realizes an accurate and fast dispensing process on an inner rounded corner or groove of a special product and has high dispensing efficiency.

Description

technical field [0001] The invention relates to the technical field of automatic glue dispensing, in particular to a method for dispensing glue with a curved needle head. Background technique [0002] In industrial production, dispensing is required in many places, such as integrated circuits, printed circuit boards, color LCD screens, electronic components (such as relays, speakers), automotive parts and so on. Traditional dispensing is manually operated by workers. With the rapid development of automation technology, manual dispensing is far from meeting the industrial requirements. Manual dispensing has the disadvantages of complex operation, slow speed, low accuracy, error-prone, and inability to operate complex graphics, let alone realize production automation. The market requires a device with high speed, high efficiency and high precision, so a fully automatic dispensing machine has appeared. [0003] For some products, it is difficult to complete the dispensing ta...
