The second embodiment:
referring to fig. 1 to 4, on the basis of the first embodiment, each end of the cross 302 is provided with a groove 304, and a limiting component 5 for limiting the component is disposed inside the groove 304, so that the component can be integrally and effectively limited when rotating along with the cross 302, and the component is prevented from being offset and dislocated due to gravity and inertia when rotating to the right side of the cross 302.
In the above configuration, the recess 304 is disposed on the left side of each end portion, so that the stop assembly 5 can move from the left side of the corresponding end portion to stop the front surface of the component when the cross 302 rotates clockwise. Meanwhile, the cross 302 in this embodiment is arranged in an "x" shape with respect to the top of the conveyor belt 203, maintaining the offset state of the end of the cross 302 with respect to the conveyor belt 203.
Referring to fig. 1 to 6, in the present embodiment, it is preferable that: the limiting assembly 5 comprises a balancing weight 501 in sliding fit with the groove 304 and a round rod 503 rotatably installed in the groove 304, a limiting block 504 flush with the surface of the end of the cross 302 is fixedly installed on the outer surface of the round rod 503, a pull rope 502 fixedly connected with the balancing weight 501 is wound on the outer surface of the round rod 503, a torsion spring (not shown in the figure) is further sleeved on the outer surface of the round rod 503, and the round rod 503 rotates anticlockwise to drive the limiting block 504 to deflect synchronously under the action of the torsion spring.
In an initial state, the counterweight block 501 is arranged on one side of the groove 304 far away from the center of the cross 302, the pull rope 502 is tensioned, so that the torsion spring cannot drive the round rod 503 and the limiting block 504 to rotate, and the surface of the limiting block 504 is flush with the surface of the end part of the cross 302 and is also vertical to the corresponding counterweight block 501; when the counterweight 501 rotates along with the cross 302 and moves towards the center of the cross 302 along the groove 304, the pull rope 502 is released, and the round rod 503 and the limiting block 504 can complete rotation under the action of the torsion spring.
In the above structure, as shown in fig. 4, two weights 501 below the cross 302 arranged in an "x" shape are located away from the center, the stop block 504 is kept flush, the two weights 501 above slide close to the center due to gravity, and at this time, the stop blocks 504 corresponding to the two weights 501 rotate counterclockwise. Meanwhile, the joint (left and right joints) of two adjacent end parts of the cross 302 is also positioned below the top of the conveyor belt 203, so as to avoid installation interference of the long rod 301 and the conveyor belt 203; moreover, in order to avoid the interference of the limiting block 504 on the parts after the turnover, the length of the limiting block 504 needs to be limited, so that the rotating limiting block 504 can ensure the fixation of the parts and cannot influence the continuous conveying of the conveying belt 203 on the parts after the turnover, that is, when the rotating limiting block 504 rotates to the right side along with the cross 302 and corresponds to the conveying belt 203, the end part of the limiting block 504 far away from the round rod 503 is not higher than the right side joint part, so that the parts after the turnover can be smoothly in complete contact with the conveying belt 203 and are conveyed continuously by the conveying belt 203, and the parts cannot be extruded and deviated from the conveying belt 203 under the influence of the rotation of the cross 302.
When the part overturning device is used, parts are placed on the left side of the conveying belt 203, the conveying belt 203 is driven to move through the matching of structures such as the motor 401, the second belt wheel 403, the first belt wheel 204 and the tooth column, the front detection is completed, the overturning and overturning of the parts are further realized through the matching of structures such as the crank 405, the disc 404, the grooved wheel 303 and the cross 302, the parts after overturning fall on the conveying belt 203 to move right, the back detection is completed, the working process of the part is the same as that in the first embodiment, and repeated description is omitted. When the component enters the left gap of the cross 302 shown in fig. 4, the cross 302 starts to rotate clockwise, the conveyor belt 203 can drive the component to move to the right during the rotation process, and finally the right side of the component is contacted with the joint of the two end parts. When the end of the cross 302 supporting the part moves above the conveyor belt 203, the counterweight 501 slides to the center of the cross 302 along the groove 304 under the action of gravity, at this time, the pull rope 502 is released to enable the limiting block 504 to rotate counterclockwise based on the round rod 503 and abut against the part, the cross 302 is matched with the limiting block 504 to drive the part to continue rotating under the state, when the back of the part contacts the conveyor belt 203, the limiting block 504 just moves to the lower part of the top of the conveyor belt 203, and at this time, the conveyor belt 203 can drive the turned part to continue moving right to complete back detection; in the above process, the parts are moved above the conveyor belt 203 along with the cross 302 when rotated by 90 degrees, and the parts are fully contacted with the conveyor belt 203 and then subsequently conveyed after rotated by 180 degrees, that is, two parts exist on the cross 302 at the same time.
In the first embodiment, although the double-sided detection of the part can be realized through the matching of the structures such as the conveyor belt 203 and the cross 302, the effective limit of the part cannot be realized in the overturning process of the part; when the parts rotate to the other side along with the cross 302, the parts can fall down and impact on the conveyor belt 203 rapidly due to gravity and inertia, which may cause the dislocation deviation of the parts to affect the subsequent detection, and may also cause damage to both the parts and the conveyor belt 203, and there is a certain use limitation. Compare in embodiment one, through cross 302, conveyer belt 203, the cooperation of structures such as balancing weight 501 and stopper 504, can realize the effective spacing and the support of the whole turn-over in-process of spare part, the spacing is automatic to be relieved after spare part after the turn-over contacts completely with conveyer belt 203, avoid spare part to rotate the natural acceleration separation to cross 302 opposite side, and then not only can avoid the dislocation deviation of spare part to guarantee follow-up detection, can also avoid spare part and conveyer belt 203 to strike the damage that brings, holistic long-term steady operation has been guaranteed. In the rotation process of the cross 302, the counterweight 501 cooperates with the gravity action and the groove 304 to automatically control the deflection of the limiting block 504, so that whether the part is limited or not is automatically controlled, the whole operation is combined with the rotation of the cross 302, and the applicability is stronger.
Example three:
referring to fig. 1 to 10, in the second embodiment, the limiting block 504 includes a base 5041 fixedly installed on the outer surface of the round rod 503, a sliding block 5042 is installed inside a side of the base 5041 away from the round rod 503 in a sliding manner, and a spring 5043 is fixedly installed between the sliding block 5042 and the base 5041, and is used for automatic return after the sliding block 5042 slides.
In the above configuration, the slide groove 5044 is provided on the front side of the base 5041, the projection 5045 slidably fitted to the slide groove 5044 and projecting forward from the slide groove 5044 is fixedly attached to the front side of the slider 5042, and the slider 5042 is horizontally slidable along the base 5041 by the fitting of the projection 5045 to the slide groove 5044, and the slider 5042 is positioned on the side of the slide groove 5044 away from the round bar 503 in the initial state by the spring 5043.
In order to realize the sliding of the sliding block 5042 along the base 5041, the short rod 402 extends into the base 5041 and is fixedly installed with the pressing block 406, when the cross 302 rotates 90 degrees and then rotates more than 45 degrees (the cross 302 is arranged in an x shape in the initial state), the projection 5045 contacts with the pressing block 406 which rotates counterclockwise along with the short rod 402, the projection 5045 is pushed to move along the sliding groove 5044 towards the round rod 503, and the sliding block 5042 is driven to retract into the base 5041.
Referring to fig. 1 to 10, in the present embodiment, it is preferable that: after the base 5041 rotates based on the round rod 503, a certain distance is left between the end part far from the round rod 503 and the joint of the two corresponding end parts, and after the slider 5042 is installed in a matching way, the height is higher than the joint of the two corresponding end parts. Meanwhile, after the slider 5042 slides and shrinks towards the base 5041 and rotates to the right along with the cross 302, the end of the slider 5042 far away from the base 5041 is not higher than the right-side junction of the cross 302, so that the turned part can be smoothly and completely contacted with the conveyor belt 203 without interference.
To facilitate the arrangement of the knobs 406 so that they do not interfere with the transport and turning of the parts, the control unit 4 is disposed entirely on the right side of the ratchet (shown in FIG. 7), where the projections 5045 may correspond to and be ready to contact the projection 5045 rotated to the right in cooperation with the "x" arrangement of the cross 302. At this time, in order to avoid interference with long rod 301, it is necessary to rotatably mount a steering member 6 in front of housing 1 to steer and tension the belt, and steering member 6 may be an existing round shaft or a tension pulley, etc., and is not limited herein.
When the part overturning device is used, parts are placed on the left side of the conveying belt 203, the conveying belt 203 is driven to move through the matching of the structures such as the motor 401, the second belt wheel 403, the first belt wheel 204 and the tooth column, the front detection is completed, the overturning and the effective support during overturning of the parts are realized through the matching of the structures such as the crank 405, the grooved wheel 303, the counterweight block 501 and the cross 302, the overturned parts fall on the conveying belt 203 to move to the right, the back detection is completed, the working process of the part is the same as that of the second embodiment, and repeated description is omitted. When the component enters the left notch of the cross 302, the cross 302 rotates clockwise, when the end of the cross 302 supporting the component moves above the conveyor belt 203, the counterweight 501 makes the base 5041 and the slide 5042 rotate counterclockwise based on the round rod 503 and abut against the component through the pull rope 502, and the slide 5042 contracts inward of the base 5041 and presses the spring 5043 under the contact action of the component; when the cross 302 drives the component to rotate 90 degrees and then rotate more than 45 degrees (at this time, the next component is also driven by the cross 302 to start moving), the bump 5045 of the slider 5042, which abuts against the component, enters the position below the top of the conveyor belt 203, at this time, the motor 401 drives the press block 406 to rotate counterclockwise through the short rod 402 to contact with the bump 5045, and pushes the bump 5045 to move along the chute 5044, so that the slider 5042 continues to contract towards the base 5041, at this time, the component can deflect clockwise along with the contraction of the slider 5042 and continuously keeps contact with the end of the slider 5042, which is far away from the base 5041, finally, the component can complete turning over and quickly make full contact with the conveyor belt 203, and then the conveyor belt 203 drives the turned-over component to continue moving right to complete subsequent back detection.
In the second embodiment, although the effective support of the part in the whole turnover process can be realized through the arrangement of the limiting block 504, the size limitation of the part and the limiting block 504 is strict, the size after the two are offset needs to be approximately equal to the size of the bevel edge corresponding to the notch, otherwise, the contact between the part and the limiting block is excessive in extrusion, which causes the practical application to be troublesome, and has certain use limitation. Compared with the second embodiment, the limiting block 504 is set to be variable in relative length by matching the structures of the balancing weight 501, the base 5041, the sliding block 5042, the pressing block 406 and the like so as to match the supporting requirements of parts with different thicknesses, and the application range of the whole body is greatly enlarged; meanwhile, the part is combined with the cross 302 in a changeable mode, so that the part is far away from one side of the center of the cross 302, the part can move along with the continuous contraction of the sliding block 5042, the rapid and comprehensive contact with the conveying belt 203 is completed, and further, on the basis of being suitable for parts with different thicknesses, the time for the part to fall onto the conveying belt 203 after turning can be shortened, the overall detection time of subsequent detection and a single part is shortened, the detection working efficiency is further improved, the overall operation is combined with the rotation of the cross 302 and the rotation of the short rod 402, and more requirements in actual use are met.
