Abstract
The utility model relates to a diode lead strain detector, comprising a rack. The diode lead strain detector has the innovation point that the upper end face of the rack is fixed with a guide sleeve which is internally provided with a guide pillar in a vertical direction, the top end of the guide pillar is fixed with a transverse supporting arm and the lower part of the guide pillar is in a worm structure, and a worm gear meshing with the worm structure is arranged on one side of the worm structure; and a servo motor is arranged below the rack and is connected with the worm gear through a reducer. The utility model has the advantages that when in use, the servo motor is started, the worm gear is used for driving the worm to rotate and descend so as to ensure that the guide pillar descends to a lower limit position, one end of a copper wire used as the lead of a diode is connected to the end part of the supporting arm, the other end of the copper wire is bound with a weight with certain weight, and at the moment, the copper wire is in a loose state; and the servo motor is started again to drive the guide pillar to slowly ascend so as to tighten the copper wire and sling the weight, therefore the strain capable of being borne by the copper wire can be measured. The utility model has simple structure and is convenient to operate.
Description
Technical field
The utility model relates to a kind of detector, particularly a kind of diode lead pulling force detector.
Background technology
In the production technology of diode lead, need carry out tensile test to copper cash as diode lead, special-purpose tension tester complex structure, instrument test price height has improved cost.
The utility model content
The technical problems to be solved in the utility model provides a kind of diode lead pulling force detector simple in structure.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of diode lead pulling force detector, comprise frame, its innovative point is: the upper surface of described frame is fixed with a guide pin bushing, be provided with the guide pillar of a vertical direction in this guide pin bushing, the top of described guide pillar is fixed with a horizontal sway brace, and the guide pillar bottom is a worm structure, and a side is provided with the worm gear with its engagement; The frame below is provided with a servomotor, and this servomotor is connected with worm gear by speed reduction unit.、
Further, the bottom of described guide pillar is connected with a horizontal gag lever post, is separately installed with the upper and lower limit bit switch at the upper and lower of this gag lever post, and described upper and lower limit bit switch is connected with servomotor by Programmable Logic Controller.
Advantage of the present utility model is: during use, start servomotor, rotate decline by the worm gear drives worm screw, make guide pillar drop to lower limit, to be connected the sway brace end as copper cash one end of diode lead, the other end is bound the counterweight of certain mass, and this moment, copper cash was in relaxed state.Restart servomotor, its drive guide pillar slowly rises, and tightens copper cash, and the counterweight of slinging, and tests the pulling force that copper cash can bear with this, and is simple in structure, easy to operate.
Description of drawings
Accompanying drawing is the utility model diode lead pulling force detector structural representation.
Embodiment
As shown in drawings, comprise frame 1, guide pin bushing 2, guide pillar 3, worm gear 5, sway brace 4, gag lever post 7, upper limit position switch 8, lower position switch 9.
The upper surface of above-mentioned frame 1 is fixed with a guide pin bushing 2, establish the guide pillar 3 of a vertical direction in this guide pin bushing 2, these guide pillar 3 bottoms are worm structure, and a side is provided with the worm gear 5 of forming gear pair with its engagement, the frame below is equipped with a servomotor, and it is connected with worm gear 5 by speed reduction unit.When starting, realizes by servomotor the lifting of guide pillar 3 by gear pair.
The top of guide pillar 3 is fixed with a horizontal sway brace 4, the bottom is connected with a horizontal gag lever post 7, upper and lower at gag lever post 7 is respectively arranged with upper limit position switch 8 and lower position switch 9, and this upper and lower limit bit switch 8,9 is connected with servomotor by Programmable Logic Controller.
During use, start servomotor, realize that by gear pair guide pillar 3 descends, after dropping to gag lever post 7 triggering lower position switch 9, the Controlled by Programmable Controller servomotor cuts out,, will be connected sway brace 4 ends as copper cash one end of diode lead, the other end is bound the counterweight 10 of certain mass, and this moment, copper cash was in relaxed state.Restart servomotor, its drive guide pillar slowly rises, and tightens copper cash, and the counterweight of slinging, and tests the pulling force that copper cash can bear with this, and guide pillar 3 rises to and stops after gag lever post 7 triggers upper limit position switch 8.
