Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.

As shown in fig. 1, 2, 3, 4 and 5, a pin shearing device for electrical components comprises a pin shearing mechanism and an element fixing mechanism, wherein the pin shearing mechanism comprises a frame 1, two carriages 2 arranged on the frame 1 in parallel and a cutter 3 arranged between the two carriages 2, the upper surfaces of the cutters 3 are at least at the same level with the upper surfaces of the carriages 2, and the cutter 3 is driven by a motor 4; the component fixing mechanism comprises a component tray 12, a tray frame 5, a tray fixing mechanism and a tray cover plate 6, a jack is formed in the component tray 12 corresponding to a component pin, the component tray 12 is movably arranged on the tray frame 5 through the tray fixing mechanism, a movable cover of the tray cover plate 6 is arranged at the top of the component tray 12, the middle of the bottom of the tray frame 5 corresponds to the jack and a cutter 3 and is opened, and two sliding frames 2 are arranged on two sides of the bottom of the tray frame 5 correspondingly.

When the component tray 12 with the proper thickness is used, the component tray 12 with the proper thickness is selected according to the requirement, the pins of the components needing to be cut are inserted into the jack, for example, the length of the pins of the required components is 2.5mm, and then the component tray 12 with the thickness of 2.5mm is selected. After the component tray 12 inserted with the components is placed into the tray frame 5, the component tray 12 is fixed on the tray frame 5 through the tray fixing mechanism, and the tray cover plate 6 is covered on the component tray 12, so that a certain auxiliary positioning effect is achieved on the components on the component tray 12, and the components are prevented from shaking on the component tray 12. The part of the component stitch longer than the required length is exposed from the bottom and the opening of the component tray 12, two sides of the tray frame 5 are abutted and erected on the two sliding frames 2, the tray frame 5 is manually pushed to move towards the direction of the cutter 3 on the sliding frames 2, and the stitch part exceeding the component tray 12 is cut off by the cutter 3 after the stitch is contacted with the cutter 3 in the moving process. In practice, since the rack 5 of the component trays 12 is provided on the tray rack 5, that is, the bottom of the component tray 12 is spaced from the bottom of the tray rack 5 by a distance (which is the thickness of the portion of the tray rack 5 supporting the component tray 12), the surface of the cutter 3 may be disposed to protrude above the level of the surface of the carriage 2 by a height to offset the thickness of the portion of the tray rack 5 supporting the component tray 12. In practice, the top of the tray frame 5 is further provided with a grab handle 9, and the grab handle 9 is used for facilitating the force application operation on the tray frame 5.

In this embodiment, tray fixed establishment includes that the hand is screwed up the bolt and is set up the rubber pad at hand screw up bolt tip, corresponds hand and screws up bolt and be provided with screw hole 7 on tray frame 5. After the element tray 12 is placed in the tray frame 5, the hand-screwing bolt is screwed, and the tail end of the hand-screwing bolt presses the two sides of the upper part of the element tray 12 against the tray frame 5 to fix the element tray 12. The rubber pad serves as a protection for the component tray 12.

The top of the tray cover plate 6 is provided with at least two pull rods 11, the top of each pull rod 11 penetrates through the top of the tray frame 5 and then is arranged on one connecting rod 8, and the top of the tray cover plate 6 is also arranged on the tray frame 5 through a spring 10; the bottom of tray apron 6 is provided with the bolster, and the bolster is sponge or silica gel pad. Pulling connecting rod 8 earlier during the use in order to pull up tray apron 6, conveniently put into tray frame 5 back with component tray 12, release connecting rod 8, tray apron 6 supports under spring 10 elasticity and self action of gravity and presses on component tray 12 top or component, plays certain assistance-localization real-time effect to the component in the component tray 12, avoids the component to rock. The sponge or silica gel pad plays a role in protecting the element.

In fact, further for the assistance-localization real-time effect and the guard action of improvement to the component, the upper portion of component tray 12 corresponds the component and is provided with the recess, and the jack setting of every stitch is in the recess, and during the use, the component is placed in the recess, and the stitch is inserted in the jack in the recess, and the lateral wall and the laminating of component outer wall of recess cooperate tray apron 6, play better location guard action to the component, rock when avoiding cutting the foot etc.. In the production process, the circuit boards are produced in batch, each component tray 12 corresponds to one type of component, and the pins of a plurality of similar components are cut simultaneously in each operation; when it is desired to trim other types of components, the corresponding type of component tray 12 is replaced.

Preferably, the component tray also comprises an adjusting tray, and the adjusting tray is also provided with inserting holes corresponding to the inserting holes on the component tray 12. Different circuit boards or users have different requirements on the length of element pins, and the pin shearing device is matched with the adjusting tray to realize the purpose when being suitable for the pin shearing with different length requirements. When the adjustable tray is used specifically, the adjustable tray is placed below the element tray 12, namely after the element tray 12 and the adjustable tray are stacked, elements are inserted on the element tray 12, element pins simultaneously penetrate through the element tray 12 and the adjustable tray, and then the element tray 12 and the adjustable tray are placed on the tray frame 5 and fixed together. The common thickness of adjusting tray and component tray 12 satisfies the requirement of cutting the foot, if need 2.5mm long component stitch, then can select the component tray 12 that 2.0mm is thick and the adjusting tray that 0.5mm is thick to use jointly, realizes the location to stitch length.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
