Description

PCB removes ink protection device

Technical Field

The utility model relates to a PCB preparation field, concretely relates to PCB deoiling china ink protection device.

Background

The printed circuit board, also known as printed circuit board, printed board for short, pcb (printed circuit board) for short, or pwb (printed wiring board), is cut into a certain size by using an insulating board as a base material, and at least one conductive pattern is attached to the insulating board and is provided with holes (such as element holes, fastening holes, metalized holes, and the like) for replacing a chassis of an electronic component in the prior art and realizing the mutual connection of the electronic component. Such boards are known as "printed" circuit boards because they are made using electronic printing. It is not exact to custom refer to a "printed wiring board" as a "printed circuit" because there are no "printed components" on the printed board, but only wiring. In the preparation process of the PCB, multiple deoiling operations are required, and the current mainstream deoiling mode is to use acid washing, put the PCB into an acid washing liquid tank through a metal frame and then take out the PCB. However, the metal frame is easy to scratch the layout, and simultaneously, all the PCB boards are overlapped together, and the mutual contact surfaces of the PCB boards cannot be washed by acid to remove the printing ink.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art's is not enough, provides a PCB deoiling china ink protection device, can effectively avoid PCB to be scraped the flower at the deoiling in-process to reduce the product disability rate.

The purpose of the utility model is realized through the following technical scheme:

a PCB ink removing protection device comprises a product frame, wherein clamping parts which are uniformly distributed are vertically arranged on the inner sides of a group of symmetrical side frames of the product frame;

a row of arched elastic reeds are arranged at the bottom of the product frame under a connecting line between the two symmetrical clamping parts;

the clamping part consists of a groove and arched reeds, the groove is vertically formed, a plurality of groups of arched reeds are oppositely fixed on the inner side of the groove, and the arched sides of each group of arched reeds are mutually abutted.

This scheme utilization arch reed is as centre gripping and support PCB board to form and the PCB board between buffer structure, and arch reed surface is smooth, can thoroughly avoid scraping colored PCB board, avoided PCB board downside direct and frame end contact simultaneously, reduced wearing and tearing, thereby protection PCB board prevents wearing and tearing at the deoiling china ink in-process.

Furthermore, the side wall and the bottom of the product frame are designed to be hollow. The hollow-out design can avoid water accumulation in the product frame in the lifting process.

Further, the width of the groove is larger than the thickness of the PCB plate, so that the PCB plate can be clamped and fixed by the arched spring pieces after being inserted along the groove.

Furthermore, the maximum deformation force borne by the elastic spring leaf is larger than the gravity of the inserted PCB. The design is to avoid the PCB bottom and the bottom of the product frame from contacting due to the pressing deformation of the elastic spring of the PCB paddle.

Further, the number of the elastic reeds in the same row is at least two.

Furthermore, two adjacent clamping parts are parallel to each other, and the groove is fixed on the inner side wall of the product frame in a bolt or welding mode.

The utility model has the advantages that:

(1) the arched elastic sheet is used as a support of the PCB, so that the contact area of the PCB is reduced, and the PCB can be comprehensively acid-washed to remove ink;

(2) the arched elastic piece is used as an elastic buffer structure, so that the PCB can be prevented from being scratched in the ink removing process.

Detailed Description

The technical solution of the present invention is described in further detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the following description.

As shown in fig. 1, a main body of the device for protecting a PCB from ink removal is a product frame 1, preferably, the product frame 1 is made of a non-metallic material to avoid corrosion of a pickling solution, in this embodiment, the product frame 1 is made of a rubber material, and the frame body of the product frame 1 is fully provided with a hollow portion to facilitate the flow-in and flow-out of the pickling solution when the product frame is lifted and put in, so that the drawing is more concise, and the hollow portion is not shown in fig. 1 to 4. In order to complete the positioning of the PCB, clamping portions which are uniformly distributed are vertically arranged on the inner sides of a group of symmetrical frames of the product frame 1, as shown in fig. 1, the inner sides of an upper frame 11 and a lower frame 12 of the product frame 1 are provided with clamping portions which are symmetrical to each other, which is equivalent to forming an upper clamping portion and a lower clamping portion for clamping two side edges of the PCB, and simultaneously, a row of arched elastic reeds 4 are arranged at the bottom of the product frame 1 right below a connecting line between every two symmetrical clamping portions; for completing the support of the PCB, the structure of which can be seen with reference to fig. 2. The whole PCB is supported by multiple points, so that shielding of local or large area is avoided, and the pickling effect can be further improved. As a preferred embodiment, the clamping part is composed of a groove 2 and arched reeds 3, the groove 2 is vertically opened, a plurality of groups of arched reeds 3 are oppositely fixed on the inner side of the groove 2, and the arched sides of each group of arched reeds 3 are abutted with each other. The structure of the PCB clamping device can be shown in figure 3, further, the width of the groove 2 is larger than the thickness of the PCB, so that the PCB can be clamped and fixed through the arched reeds 3 after being inserted along the groove 2, and the clamping state can be shown in figure 4.
