Description

Electron YuanJianJianCeZhuangZhi

Technical field

The utility model belongs to Electron YuanJianJianCeZhuangZhi, particularly a kind of Electron YuanJianJianCeZhuangZhi.

Background technology

The system to be measured of traditional is electronic component is made up of plastic body and sheet metal.The plastic body periphery is provided with the plural number equally spaced short slot of being separated by, and its end face middle position is provided with the protuberance of external diameter less than body.Sheet metal just can be smooth in the plastic body bottom surface, and the short slot position is respectively equipped with bent sheet on the relative plastic body of its periphery, bent sheet along the bending of the short slot of plastic body with closing in the plastic body end face is separated by the position of suitable spacing near protuberance on.So, bent sheet bending back and the spacing between the protuberance need meet the regulation of relevant safety standard, when surveying thing and be installed on the object to avoid waiing upon, protrude from situation about making a mistake when protuberance causes object motion because of bent sheet.

General plastic body and sheet metal system combine in the mode of automatic assembling, and it ties up on the assembly platform, is placed on the tool in regular turn respectively by automatic conveying device sheet metal and plastic body, and makes plastic body place on the sheet metal; With bending device with the bent sheet of sheet metal along the short slot bending closing of plastic body at the end face of plastic body and near the protuberance of plastics material body, can be with the determinand of plastic body and sheet metal assembling becoming electronic component, in the hope of the quality of producing, increase competitiveness of product, raising product fast and the cost that reduces artificial assembling.

Yet, plastic body and sheet metal are in the robotization assembling process, often do not put and factor such as scale error according to the tram because of malfunction, plastic body or the sheet metal of plant equipment, cause the bent sheet of sheet metal not bent closing on the close protuberance position of the end face of plastic body along short slot, or the bent sheet of sheet metal is not bent at all, and then, when being installed on it on object, protrude from the protuberance of plastic body, the situation that causes the thing uncle when action, to make a mistake because of the bent sheet of sheet metal.So after plastic body and sheet metal are assembled into determinand automatically, must check bent sheet whether to be bent usually, and closing is on the close position of protuberance of plastic body end face.

Because the determinand size is less, the size of bent sheet is especially much smaller than determinand, whether therefore be difficult for observing out bent sheet with eyes is bent on the correct position, and if also will violate originally the original idea of assembling determinand automatically by the mode of manually observing with eyes, so generally whether the bent sheet that all detects thing to be detected with laser detection equipment or high precision image checkout equipment is bent on the correct position.But laser detection equipment, image checkout equipment etc. involve great expense, not easy-maintaining, maintenance, and causing increases manufacturing cost, causes inconvenience and the puzzlement used.

Embodiment

As shown in Figure 1 and Figure 2, traditional for the determinand 1 of electronic component be to form by the sheet metal 12 of plastic body 10 and tool conductive characteristic.Sheet metal 12 is smooth in plastic body 10 bottom surfaces.Be arranged at a plurality of bent sheet 120 on the sheet metal 12 and be plural short slot 100 bendings along plastic body 10, and closing in plastic body 10 end faces near on the position of protuberance 102.Suitable spacing that the bent sheet 120 of sheet metal 12 is bent afterwards and the protuberance 102 of plastic body 10 end faces is separated by, and since plastic body 10 and sheet metal 12 in the robotization assembling process, sheet metal 12 is placed plastic body 10 after being placed on the tool 2 again; And then the bent sheet 120 of sheet metal 12 bent, so sheet metal 12 is in assembling process, with the state that keeps joining with tool 2 always.

The utility model system utilizes spacing, the sheet metal 12 between plastic body 10 end face peripheries and the protuberance 102 and has the conductive characteristic design that state, plastic body 10 that conductive characteristic tool 2 joins have nonconducting insulation characterisitic and sheet metal 12, use detect determinand 1 sheet metal 12 bent sheet 120 whether along the short slot 100 of plastic body 10 by the bending closings on the close tram of protuberance 102 of the end face of plastic body 10.

As shown in Figure 1, the utility model comprises driver 6, testing element 3, contact element 4 and testing circuit 5.

Testing element 3 and contact element 4 are mounted on the driver 6 and with driver 6 actions and produce displacement synchronously, and then testing element 3 and contact element 4 are pressed against respectively on determinand 1 and the tool 2 simultaneously.

The testing element 3 that is mounted on the driver 6 is faced the bent sheet 120 of determinand 1 sheet metal 12 and the protuberance 102 of plastic body 10, and, be pressed against on the protuberance 102 so that the part of its relative plastic body 10 protuberances 102 is removable at driver 6 drive bottom offsets.

Be mounted on the adjacent position of the contact element 4 network topology testing elements 3 on the driver 6, and under driver 6 drives with testing element 3 synchronous shift, promptly when testing element 3 was pressed against on plastic body 10 protuberances 102, contact element 4 just can be pressed against on the tool 2.

Two

electrode tips

51,52 of testing circuit 5 are connected with testing element 3 and contact element 4 respectively, are provided with reaction signal element 50 in testing circuit 5.

When detecting determinand 1 with the utility model, if the bent sheet 120 of sheet metal 12 is protuberance 102 states that protrude from plastic body 10 end faces, testing element 3 also is pressed against on the bent sheet 120 that is convex shape when pressing plastic body 10 protuberances 102, make testing element 3, bent sheet 120, tool 2, contact element 4, the electrode tip 52 that is connected with contact element 4, the electrode tip 51 and the reaction signal element 50 that are connected with testing element 3 are connected, and then make testing circuit 5 form the closed-loop path state, reaction signal element 50 actions this moment, bent sheet 120 with expression sheet metal 12 is not bent closing on close protuberance 102 positions of the end face of plastic body 10 along the short slot 100 of plastic body 10, or the bent sheet 120 of sheet metal 12 is not bent at all.

Driver 6 is provided with socket part 60 with the position that testing element 3 joins; Testing element 3 extends to slide and wears and protrude out the body of rod 30 of socket part 60, and is provided with in the body of rod 30 tops to use the body of rod 30 is remained on flange part 34 socket part 60 in, and it is faced determinand 1 one ends and is provided with the portion of pressing 32; Press flexible member 7 between portion 32 and driver 6 socket parts 60 in being arranged with on the body of rod 30 at testing element 3, and make testing element 3 to distance that determinand 1 moves less than flexible member 7 compression,metal-to-metal positions to the distance between the determinand 1, pressing portion 32 with order can be pressed against on the determinand 1 really.

When as shown in Figure 2, plastic body 10 protuberances 102 central authorities are provided with lip portions 1022.Testing element 3 presses portion 32 bottom surfaces and is provided with and plastic body 10 protuberances 102 central lip portions 1022 corresponding depressed parts 322.When being moved on the determinand 1 to drive testing element 3 when driver 6, it presses portion 32 and just can fit on the protuberance 102.So, as long as bent sheet 120 is when protruding from protuberance 102 states, kink 120 will contact with the portion of pressing 32, and then make 50 actions of reaction signal element.

Contact element 4 is provided with at least one probe in the face of the end face of tool 2, probe is arranged in the hollow lever, it comprises spring and the needle body that is arranged in regular turn in the hollow lever, and make needle body partly protrude from the body of rod one end, treat probe move touch tool after, can move forward suitable distance again, make needle body touch and littlely behind the tool inwardly contract, touch tool 2 to guarantee probe.
