The tool is adopted as supplementary to manual operation, preventing elements from being exposed beyond package, facilitating operation standardization and significantly enhancing the working efficiency.
Description
Technical field
The utility model relates to a kind of frock, particularly relates to the frock of using in a kind of circuit board three anti-lacquer sprayings.
Background technology
Circuit board and electronic devices and components are in use, can be given a shock, the impact of the environment such as humidity, salt fog, mould, high temperature, circuit board and associated electrical product thereof exist because of corrosion, short circuit, the problem such as go mouldy and cause the hidden danger that the product electric property is impaired even break down.
In order to evade above-mentioned quality risk; circuit board needs to be coated on three anti-lacquers (moistureproof, anti-salt fog, mould proof) surface of circuit board before assembling; form one deck three anti-protective films; effectively buffer circuit plate and associated electrical product thereof and the external world contacts; exempt from erosion and the destruction of adverse circumstances, thereby improve the reliability of product, increase its coefficient of safety; guarantee under the normal prerequisite of using, greatly to increase the service life.
Circuit board surface has some binding posts, must carry out shutoff and covers terminal before the three anti-lacquer sprayings, avoids painting wrapping and causes loose contact after the terminal pins, opens circuit.
Industry mainly contains two kinds of ways for circuit board three anti-lacquer sprayings at present:
The first is to adopt automatic spraying machine, by numerical control program circuit board is carried out selective spray, can solve terminal shutoff problem, but equipment manufacturing cost is expensive, lowest price is 150,000 RMB, and the cost recovery time is longer, is not suitable for medium-sized and small enterprises and uses and produce as a trial;
The second is to adopt manual mode shutoff binding post, wraps up and twines with the element of U.S. line paper to the needs protection first, the binding post pin is protected, and then spray.Adopt this pure manual mode to have following shortcoming:
1. all elements need manual parcel, and operating efficiency is low;
2. operating personnel's work mistake easily causes the subelement bottom pour ladle to wrap up in;
3. U.S. line paper is subject to easily coming off after spray pressure impacts, thereby causes component pin to be stained with lacquer;
4. adopt in the process of U.S. line paper shutoff binding post, can need to spray the part of three anti-lacquers on the shield portions circuit board, thereby cause this partial circuit plate can not be subject to the protection of three anti-lacquers, and affect product appearance.
The utility model content
The purpose of this utility model is exactly the problem for above-mentioned prior art, provide a kind of with low cost, efficient is high, the reliable circuit board of spraying effect three anti-lacquer spraying frocks, can solve the problems of the technologies described above fully.
The purpose of this utility model realizes by following technical proposals:
A kind of circuit board three anti-lacquer spraying frocks; comprise the base and the top cover that removably connect; correspondence is offered the spraying mouth on base and the top cover; the electrically-conducting metal surface of the spraying mouth both sides corresponding circuits backboard face on the base is provided with rubber protection pad, and the binding post on the corresponding circuits plate of top cover bottom surface arranges corresponding protector.
As preferably, described base and top cover are square frame-shaped.
As preferably, base is connected cross buckle to connect with top cover.
As preferably, the base bilateral symmetry arranges a pair of Button Block, and correspondence position is offered locating aperture on the top cover.
As preferably, described cross buckle is made of Button Block and swivel head, and swivel head is rotatably connected on the Button Block.
As preferably, described base and top cover all adopt anti-static glass fiber to make.
As preferably, described rubber protection pad adopts antistatic rubber to make.
The beneficial effects of the utility model are: simple in structure, reasonable in design, easily operation is cheap for manufacturing cost, adopts the auxiliary handwork of frock, and the situation of avoiding the element bottom pour ladle to wrap up in occurs, and is conducive to the operating type standardization, and operating efficiency significantly improves.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional structure chart behind the utility model clamping circuit board.
Embodiment
Below in conjunction with specific embodiments and the drawings the utility model is further described.
As depicted in figs. 1 and 2; a kind of circuit board three anti-lacquer spraying frocks; comprise the base 1 and the top cover 2 that are square frame-shaped; base 1 and top cover 2 adopt cross buckle to removably connect; two cross buckle symmetries are installed in base 1 both sides; correspondence is offered U-shaped locating aperture 3 on the top cover 2; described cross buckle is made of Button Block 7 and swivel head 8; swivel head 8 is rotatably connected on the Button Block 7; correspondence is offered spraying mouth 4 on base 1 and the top cover 2; the electrically-conducting metal surface 11 at corresponding circuits plate 9 back sides, spraying mouth 4 both sides on the base 1 is provided with rubber protection pad 5, and the binding post 10 on the top cover 2 bottom surface corresponding circuits plates 9 arranges corresponding protector 6.
Described base 1 and top cover 2 all adopt anti-static glass fiber to make, and described rubber protection pad 5 adopts antistatic rubber to make.
In use, base 1 lies on the work top, circuit board 9 is placed in the spraying mouth 4 of base 1, then with top cover 2 from covering circuit board 9, after base 1 cooperatively interacts with top cover 2, the swivel head 8 of cross buckle rotates 90 °, and base 1 and top cover 2 are linked together, and circuit board 9 is fixed between base 1 and the top cover 2.At this moment; just in time expose the part that circuit board 9 back sides need to spray in the spraying mouth 4 of base 1; the part of just in time exposing circuit board 9 positive needs sprayings in the spraying mouth 4 of top cover 2; the electrically-conducting metal surface 11 at circuit board 9 back sides is just in time blocked by rubber protection pad 5, and the binding post 10 on the circuit board 9 just in time protected groove 6 covers.Carry out at last paint spraying, respectively circuit board 9 front and backs are carried out the spraying of three anti-lacquers.
Above-mentioned cross buckle is fool-proof design, when base 1 cooperate with top cover 2 not in place, exist ooze, during the holiday risk, cross buckle can not be locked; Only have when base 1 and top cover 2 to cooperate fully when putting in place, cross buckle just can be locked.At this moment, electrically-conducting metal surface 11 and binding post 10 on the circuit board 9 are blocked by spraying frock fully, do not exist ooze, the risk of holiday.
This shows, adopt this spraying frock to carry out circuit board three anti-lacquer sprayings, be conducive to the operating type standardization, thereby greatly raise labour efficiency.Avoid oozing lacquer and holiday because of what manual operations error caused, prevent that U.S. line paper from covering the lacquer amount non-uniform phenomenon that causes and occuring.
For dissimilar circuit board 9, can corresponding adjustment base 1 on position and the shape of rubber protection pad 5, and shape, position and the quantity of protector 6 on the top cover 2.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
