Description
Technical field
The utility model relates to a kind of pick-up unit field, is specifically related to a kind of device of automatic detection length.
Background technology
When production small size typical products in mass production, need sometimes the length or the weight of single product are detected.When the length requirement of this product or weight require generally to adopt the sampling observation mode to carry out when very harsh, still, can not guarantee that each product all meets the requirements.For example: produce the employed getter mercury dispenser of cold-cathode fluorescence lamp (CCFL), this product is a material of producing cold-cathode fluorescence lamp.Mercury content to this product requires and strictness.As Fig. 1 a, shown in the b, the diameter of single product is generally about 0.8 ~ 2mm, and length is about 1 ~ 10mm, and unit weight is about several milligrams to tens milligrams.If need control the mercury content in this product aborning, must accurately control the wherein fill-up of mercurous powder.And use traditional weight method to measure, for the object of measuring several milligrams to tens milligrams, need service precision be the analysis sky chessboard of per mille to ten thousand/gram degree or electronics sky chessboard as survey instrument, efficient is very low.General these means are the sampling observations as this product.When the diameter of this product and density are determined, its weight of control that also can convert by the length of controlling this product,
As formula: length=weight/(density * π * radius * radius)
Because generally between 0.01 ~ 1mm, survey instrument generally adopts the dial gauge slide calliper rule to the tolerance of length, instruments such as micrometer callipers or projection device, the efficient of measurement is very low, usually as the sampling observation method.
Summary of the invention
In order to solve prior art problems, the utility model provides a kind of device of automatic detection length, fast and accurately the length of measurement products.
The device of the said automatic detection length of the utility model comprises and placing or the fixing loading device of object under test, at an end of loading device spacing thimble is arranged, and the other end has the detection thimble; The axle center of one lever is fixed on the loading device, and an end of lever is connected with the detection thimble, and the other end is a free end, is rotated along the axle center by the mobile drive lever that detects thimble; Be respectively equipped with probe in the free-ended both sides of lever.
Said lever is a multiplying lever in the such scheme, from the axle center to free-ended distance greater than the axle center to the other end.
Said probe in the such scheme, the position that the free end of lever when being arranged on determinand length and being lower limit is arrived, the position that the lever free end was arrived when another probe was arranged on determinand length and is higher limit.
In the device of the present utility model, the separation and collection device can also be set below the loading device.Said separation and collection device comprises sorter and collects box, sorter be have in the inlet, the pipeline of two outlets, wherein be provided with shift fork, the swing by shift fork realizes that an outlet is open, another port closing is collected box and is positioned at the outlet below.The swing of described shift fork is the electrical control that started by probe signal.
In the device of the present utility model, can also comprise pay-off, the pay-off determinand is delivered to the loading device one by one.Described loading device is mould or anchor clamps.
Said spacing thimble can be fixed in the utility model, also can be movable, for movable spacing thimble, can move to and rest on default position during work, it gives the pressure of determinand greater than detecting thimble for the pressure of determinand.
Device of the present utility model can be differentiated qualified and unacceptable product totally, the automaticity height, and speed is fast, the efficient height.
Description of drawings
Fig. 1 is the front elevation of the utility model one specific embodiment,
Fig. 2 is the vertical view of device,
1-product to be measured, the 2-vibrating bunker, the 3-delivery chute, 4-mould or anchor clamps, the spacing thimble of 5-, 6-detects thimble, the 7-lever, 8-first probe, 9-second probe, the 10-shift fork, 11-first collects box, and 12-second collects box.。
Embodiment
The device of a concrete automatic detection length such as Fig. 1 and Fig. 2; This product 1 to be measured is by the automatic feeding as forms such as vibrating bunker 2 and delivery chutes during work, send into the mould or the anchor clamps 4 in zone to be measured, when this mould or anchor clamps 4 should guarantee to measure, this product 1 kept same axial with spacing thimble 5 and detection thimble 6.After product 1 entered mould or anchor clamps 4, spacing thimble 5 and detection thimble 6 moved to this product 1.The pressure that requires spacing thimble 5 is greater than detecting thimble 6, and spacing thimble 5 stops at same fixed position; And the pressure that detects thimble 6 must not destroy this product 1 or make this product 1 be deformed into principle.The general power source that detects thimble 6 can be flexible force such as pneumatic, hydraulic pressure, spring.That is to say that spacing thimble 5 is parked in the fixed position, the position of detecting thimble 6 is parked in different positions along with the length difference of product 1.The A of lever 7 end moves together and drives its B end (free end) and rotate along with detecting thimble 6, when this lever A, B hold to rotation center O point adopt different arms apart from the time, can so that the amplification of measurement range or dwindle (generally according to the demand of measuring accuracy, with the BO(axle center to free-ended distance) 〉=AO(axle center to the distance that detects thimble)).For example: when BO:AO=1:5, when promptly the A point moved 0.1 millimeter, the B point moved 0.5 millimeter, and the measurement sampling spot of this device is the B point, so the B point amplifies than the displacement of A, and the accuracy of convenient measurement and measurement.The stop position of ordering owing to B also is that the length variations along with measured product changes, and therefore, when determining the length tolerance scope of this product, also promptly can determine the acceptability limit and the underproof scope of the shift position that B is ordered.Two measuring sondes 8 and 9 are installed before and after lever B point, and when the length upper limit sample of measured product was put into mould, the B point contacted with first probe 8 or responds to; When the length lower limit sample of measured product was put into mould, the B point contacted with second probe 9 or responds to.Two probe mounting positions can adjust according to the length and the margin tolerance of different product.
When this measurement mechanism detects the induced signal of first probe, 8 or second probe 9, can differentiate the whether qualified of this product.When detecting unacceptable product, can machine be stopped automatically by control circuit, this unacceptable product is taken out separate.Perhaps adopt opening-closing structure at this mould or anchor clamps 4, make product after measuring end, can drop out from mould or anchor clamps 4 lower ends, in the exit automatic sorting device is installed, shift fork 10 wherein is installed, the action of shift fork 10 is by the controls such as 8,9 signal and related electric machinery thereof of popping one's head in.Certified products and unacceptable product are flowed into respectively as the first collection box 11 and second collect box 12, thereby can realize automatic one hundred percent inspection.
Device of the present utility model can be differentiated qualified and unacceptable product totally, the automaticity height, and speed is fast, the efficient height.Probe can use the contact or the inductive switch of contact, and is cheap.
