Description

TECHNICAL FIELD

[0001] The utility model relates to capacitor production machinery technical field, specifically point to a kind of material placing mechanism for capacitor production. BACKGROUND

[0002] In the capacitor production process, after winding on the winding machine is completed, the capacitor needs to be taken off from the winding machine and placed well to carry out the next step operation such as liquid immersion. The potentiometer after winding is a semi-finished product, and the structure and form are not stable. The impact during the material placing process will cause defects. During the winding process of the winding machine, the capacitor is placed horizontally, and during the placing process, short circuit detection is also needed, and the short circuit defective products are sorted out. Therefore, when placing the material, the material is usually clamped by a suspended material receiving clamp and then placed into the conveying channel, so that the defective products can be directly discharged to complete the sorting. Therefore, during the material placing process of the material placing mechanism, the capacitor needs to be clamped and rotated by 90°, and the capacitor needs to be pulled out horizontally from the winding machine when taking the material. When placing the material, due to the limited clamping space of the material receiving clamp, interference is easy to occur, and the capacitor can only be inserted vertically. In addition, the capacitor needs to be inserted vertically into the material receiving clamp to a sufficient depth, so that when the material receiving clamp translates the capacitor and places it into the conveying channel, the capacitor will not fall due to the height difference. Therefore, the movement path of the material placing mechanism for taking the capacitor from the winding machine and placing it into the material receiving clamp is relatively complex, and the use of step-by-step action not only reduces the production speed, but also complicates the structure. It is necessary to improve. UTILITY MODEL CONTENTS
