Problems solved by technology

[0003] In order for the airbag ring to gradually change from shriveled to bulging, the acid solution will be poured through the connecting ring, but the moment the acid solution enters, a strong airflow will be generated to instantly stretch the capsule between the connecting ring and the delivery tube so tight that the capsule breaks away from the restriction of the connecting ring and breaks free upwards. With the strong airflow floating on the connecting ring, the clamping position of the connecting ring and the delivery tube on the capsule is not accurate, and it is difficult to ensure that the inside of the airbag ring is in a sealed state

Embodiment 1

[0028] Such as Figure 1-Figure 4 As shown, the present invention provides a chip pickling machine, the structure of which includes a side door 1, an infusion head 2, a cabinet 3, and a control panel 4, the side door 1 is hingedly connected to the outside of the cabinet 3, and one side of the cabinet 3 is welded and connected There is a control panel 4, which is electrically connected to the infusion head 2. The chassis 3 includes a body 31, a conversion tube 32, a delivery tube 33, a storage box 34, and an airbag ring 35. The body 31 An infusion head 2 is welded on the top, and a conversion tube 32 is fixedly connected between the delivery tube 33 and the infusion head 2. The bottom of the delivery tube 33 is indirectly matched with the storage box 34 through an air bag ring 35, and the air bag ring 35 includes Top handle 351, connecting ring 352, booster device 353, capsule membrane 354, four top handles 351 are arranged along the circumscribed circle of the delivery pipe 33...

Embodiment 2

[0030] Such as Figure 5-Figure 8As shown, on the basis of Embodiment 1, the present invention combines the mutual cooperation of the following structural components. The position control member 53b includes a tensioning plate 53b1, a guide plate 53b2, a pressing plate 53b3, a convex buckle 53b4, a clamping device 53b5, and a spring 53b6 The opening and closing plate 53b1 is provided with two, which are respectively installed on both sides of the clamping device 53b5, and a spring 53b6 is fixedly connected inside it, and the guide plate 53b2 is obliquely welded and connected between the opening and closing plate 53b1 and the pressing plate 53b3. The pressing plate 53b3 is embedded and connected inside the Y-shaped structure of the support fork 53d through the convex buckle 53b4, and the opening and closing plate 53b1 adopts indirect cooperation with the upper arched surface of the wing 53f, so that the opening and closing plate 53b1 shrinks along the outer clamping device 53b5 ...

Abstract

The invention discloses a chip pickling machine. The chip pickling machine structurally comprises a side door, a liquid conveying head, a machine box and a control panel; the side door is connected to the outer side of the machine box; one side of the machine box is connected with the control panel; the control panel is electrically connected with the liquid conveying head; an assisting device is provided with position control pieces and pinching structures; the position control pieces and the pinching structures are matched with each other on a supporting fork; when a capsule membrane is instantly expanded and tightened by strong airflow, upward struggling force can be generated, the position control pieces can relatively rub against each other to clamp the periphery of the capsule membrane and incline towards the inner side of the capsule membrane; support assistance is provided for the supporting fork through the pinching structures according to the inclination direction, positioning of the capsule membrane by the internal structure of the supporting fork is enhanced, and plastic damage of the capsule membrane is prevented.

Description

technical field [0001] The invention relates to the field of chip processing, in particular to a chip pickling machine. Background technique [0002] In order to ensure the high efficiency and normal use of electronic products, there are more complicated and rigorous steps in the production process of diodes: lead orientation, chip screening, chip loading, welding, pickling, gluing, baking, plastic packaging, post-curing , electroplating, printing test, external inspection, and packaging are continuous production, and pickling equipment is used for pickling treatment. The existing chip pickling machine will have the following disadvantages during use: [0003] In order for the airbag ring to gradually change from a shriveled shape to a bulging shape, the acid liquid will be poured through the connecting ring, but the moment the acid liquid enters, a strong airflow will be generated to instantly stretch the capsule between the connecting ring and the delivery tube Tight, so...
