[0002] In the production process of the clamp, the clamp itself has three parts, two sets of clamp bodies and a set of torsional springs, and the three parts need to be assembled after the production of the parts is completed. Since the clamp body and the torsional spring need to be oriented during assembly, the parts are reversed in direction in advance during the production process, so that each part is aligned in the same direction during transmission. Therefore, the subsequent assembly process can be facilitated, and the equipment required for aligning and selecting the parts includes transmission, screening and pre-storage. Therefore, how to effectively reverse and screen the torsional springs in this production process is an important process in production. In the past, the process was manually reversed to the same direction by artificial means. However, due to the large number of repetitions of this process, it is easy to make mistakes for the artificial. SUMMARY
[0003] To solve the above technical problems, the utility model provides an automatic spring equipment for automatic clamp assembling machine, which places the completed torsional spring in the return chute, and the feeding roller brings the torsional spring to the top of the feeding channel during rotation. Under the action of gravity, the torsional spring falls into the feeding channel, and under the continuous vibration of the vibrator, the torsional spring gradually moves forward and is screened to the correct position and then guided out of the discharging channel, realizing the effect of automatic screening.

[0007] The screening assembly comprises a screening groove and a vibrator, the screening groove is arranged on the vibrator, the vibrator is detachably connected to the support, the screening groove is sequentially connected by a feeding channel, a turnover channel, a profiling channel and a discharging channel, the feeding channel extends into the feeding roller and is located below the lifting blades, and the torsional spring is displaced in the screening groove under the vibration of the vibrator; the feeding channel comprises a receiving plate, a feeding groove and a single-sided bridge, the feeding groove is sunken at the lower end of the receiving plate, and the feeding groove is connected with the turnover channel through the single-sided bridge; the turnover channel comprises a turnover groove and a distribution groove, the turnover groove is sunken and connected to the lower end of the single-sided bridge, a turnover block is arranged on the side wall of the turnover groove, the turnover groove is connected with the profiling channel through the distribution groove, and a distribution port is arranged on the side wall of the distribution groove; the profiling channel has a U-shaped structure, and an anti-blocking port is arranged on the profiling channel.
[0008] The automatic spring feeding device for the automatic clip assembling machine adopts the structure, the torsion spring is combined by the elastic part bent and wound and the clamping part extending straight upward, after the production of the torsion spring is completed, the batch of torsion springs are fed into the feeding groove through the conveying belt or the feeder, the feeding groove is inclined to the lower end of the feeding roller, therefore, under the action of the weight, the torsion springs are stacked below the feeding roller, since the feeding roller continuously rotates under the drive of the driving motor, and the blocking plate on the radial plane of the feeding roller is provided with the circumferential array of the slots, therefore, the torsion springs enter the return groove from the slots, the return groove is also inclined to the lower end of the feeding roller, therefore, the torsion springs are driven to the upper end of the feeding roller by the lifting blade in the process of the continuous rotation of the feeding roller, and the dropped torsion springs are kept below the feeding roller under the action of the weight, the lifting blade and the blocking plate form a storage groove in the direction from the return groove to the feeding roller, the slots are arranged between the storage groove and the adjacent lifting blade, the end of the lifting blade is provided with the upward lifting blocking part, therefore, in the process of the continuous counterclockwise rotation of the feeding roller, the blocking part is inserted into the return groove, and a plurality of torsion springs are scooped up, in the process of the continuous counterclockwise rotation, the torsion springs are brought to the upper end of the feeding roller, before reaching the upper end, the existence of the blocking part can ensure that the torsion springs do not fall out in the middle of the way, and when the torsion springs are brought to the upper end, the blocking part loses the blocking effect, therefore, the torsion springs fall to the lower screening assembly under the action of the gravity.
[0009] The torsion spring on the screening assembly enters the feeding channel in the screening groove under the action of the natural gravity, the receiving plate on the feeding channel guides the torsion spring into the feeding groove, at this time, the screening groove is installed on the vibrator, the amplitude of the vibrator near the feeding channel is large, therefore, the torsion spring in the feeding groove continuously moves to the direction of the single-side bridge in the large-amplitude vibration, until entering the single-side bridge, the single-side bridge is used to ensure that only one torsion spring can pass through the position, the multiple torsion springs in the same row and parallel, or the gravity unbalanced torsion spring with the clamping part below and the elastic part above, directly falls into the return groove below, when the torsion spring gradually passes through the single-side bridge, enters the turnover groove in the sinking state, the turnover block is arranged on the side wall of the turnover groove, at this time, the torsion spring on the single-side bridge has three conveying states of the elastic part in front, below and behind.
[0010] When the elastic part is in front, the heavier elastic part directly falls into the turnover groove under the action of gravity, so that the elastic part is turned down; when the elastic part is down, the front end of the elastic part extending into the turnover groove is inclined downward, and the clamping part is abutted on the turnover block due to the limiting of the turnover block, so that the elastic part is kept in the vibration and moves forward, thereby falling into the turnover groove, so that the elastic part is downward; when the elastic part is in rear, the clamping part is first abutted on the turnover block, and the clamping part is lifted by the turnover block in the process of keeping moving forward, the torsional spring continues to move forward, and finally the elastic part falls into the turnover groove, at this time, the elastic part may be up or down.
[0011] The torsional spring entering the turnover groove keeps moving forward and enters the distribution groove, and the distribution port on the distribution groove is located at the lower end of the side wall of the distribution groove; when the elastic part is down, the elastic part is kept in close contact in the distribution groove, and the clamping part keeps abutting on the side wall of the distribution groove after crossing the distribution port; when the elastic part is up, the clamping part is abutted in the distribution groove, and due to the insufficient close contact of the clamping part itself in the large-amplitude vibration, the torsional spring falls into the return groove from the distribution port.
[0012] The torsional spring after the distribution groove comes to the profiling path, and the U-shaped structure of the profiling path is large at the lower end and small at the upper end, the lower end can just allow the elastic part to pass, and the upper end can just allow the clamping part to pass, so that the torsional spring with the elastic part up which accidentally passes through the distribution port cannot pass through the profiling path, and finally enters the discharge path after screening, and the anti-blocking port can effectively prevent the torsional spring from being blocked.
[0013] Further, the discharge path is in a U-shaped structure, and the upper end opening of the discharge path is provided with an inwardly extending blocking part.
[0014] Compared with the prior art, the advantages of the utility model lie in that: through the mutual upward inclination of the feeding groove and the return groove, the torsional spring in the feeding groove and the return groove can keep at the bottom position, and then the torsional spring is driven to the upper end of the screening groove by the lifting blade on the feeding roller in the rotation process and falls under the action of gravity, the torsional spring in the screening groove keeps moving forward under the continuous vibration of the vibrator, finally, only the torsional spring with the elastic part down and the clamping part up can finally enter the discharge path through the step-by-step screening of the single-side bridge, the turnover groove, the distribution groove and the profiling path, and finally the position conversion and screening of the torsional spring are completed, and the subsequent assembly process is facilitated.

[0029] The working mode of the utility model is described as follows:
[0030] The automatic spring feeding device for the automatic clip assembling machine adopts the structure, the torsion spring 3 is combined by the elastic part 31 and the clamping part 32, the torsion spring 3 is fed into the feeding groove 122 by the conveying belt or the feeder after the production is completed, the feeding groove 122 is inclined to the lower end of the feeding roller 131, so that the torsion spring 3 is stacked below the feeding roller 131 under the action of the weight, the outer gear ring 1311 is rotated to drive the feeding roller 131 to rotate under the driving of the driving motor 133, the outer side wall of the feeding roller 131 is limited in the circumferential space surrounded by the support wheel group 1323, so that the feeding roller 131 can keep stable and continuous rotation, and the blocking plate 1313 on the radial plane of the feeding roller 131 is provided with a circumferential array of slots 1314, so that the torsion spring 3 enters the return groove 121 from the slot 1314, the return groove 121 is also inclined to the lower end of the feeding roller 131, so that the torsion spring 3 is driven to the upper end of the screening assembly 2 by the lifting blade 1312 during the continuous rotation of the feeding roller 131, and the torsion spring 3 falling under the action of the weight is kept below the feeding roller 131, the lifting blade 1312 and the blocking plate 1313 form a storage groove 1315 from the return groove 121 to the feeding roller 131, the slot 1314 is arranged between the storage groove 1315 and the adjacent lifting blade 1312, and the end of the lifting blade 1312 is provided with a blocking part 1316 raised upward, so that during the continuous counterclockwise rotation of the feeding roller 131, the blocking part 1316 inserts into the return groove 121, and a plurality of torsion springs 3 are scooped up, the torsion spring 3 is brought to the upper end of the feeding roller 131 during the continuous counterclockwise rotation, and the torsion spring 3 cannot fall out in the middle due to the existence of the blocking part 1316 before reaching the upper end, and the blocking part 1316 loses the blocking effect when the torsion spring 3 is brought to the upper end, so that the torsion spring 3 falls to the screening assembly 2 below under the action of the gravity.
[0031] The torsion spring 3 on the screening assembly 2 will enter the feeding channel 211 in the screening groove 21 under the action of natural gravity, and the receiving plate 2111 on the feeding channel 211 will guide the torsion spring 3 into the feeding groove 2112. At this time, the screening groove 21 is installed on the vibrator, and the amplitude of the vibrator near one end of the feeding channel 211 is larger, so that the torsion spring 3 in the feeding groove 2112 will continue to move in the direction of the single-side bridge 2113 in the large-amplitude vibration, until it enters the single-side bridge 2113. The single-side bridge 2113 is used to ensure that only one torsion spring 3 can pass through this position. The torsion spring 3 in the same row and parallel to each other, or the gravity unbalanced torsion spring 3 with the buckle part 32 below and the elastic part 31 above, will directly fall into the return groove 121 below. When the torsion spring 3 gradually passes through the single-side bridge 2113, it enters the turnover groove 2121 in the sinking state, and the turnover block 2123 is arranged on the side wall of the turnover groove 2121. At this time, the torsion spring 3 on the single-side bridge 2113 has three transmission states of the elastic part 31 in front, below and behind.
[0032] When the elastic part 31 is in front, the elastic part 31 with a heavier weight directly falls into the turnover groove 2121 under the action of gravity, so that the elastic part 31 is turned downward. When the elastic part 31 is below, the elastic part 31 extending into the front end of the turnover groove 2121 will be inclined downward, and the buckle part 32 will be abutted on the turnover block 2123 due to the limitation of the turnover block 2123 at the upper end, so that the elastic part 31 will be kept in the process of moving forward in the vibration, thereby falling into the turnover groove 2121 and making the elastic part 31 downward. When the elastic part 31 is behind, the buckle part 32 first abuts on the turnover block 2123, and the buckle part 32 is lifted by the turnover block 2123 in the process of keeping moving forward, the torsion spring 3 continues to move forward, and finally the elastic part 31 falls into the turnover groove 2121. At this time, the elastic part 31 may be above or below.
[0033] The torsion spring 3 entering the turnover groove 2121 will keep moving forward and enter the distribution groove 2122. The distribution port 2124 on the distribution groove 2122 is located at the lower end of the side wall of the distribution groove 2122. When the elastic part 31 is below, the elastic part 31 is kept in close contact in the distribution groove 2122, and the buckle part 32 will keep abutting on the side wall of the distribution groove 2122 after crossing the distribution port 2124. When the elastic part 31 is above, the buckle part 32 abuts in the distribution groove 2122. Due to the fact that the buckle part 32 itself is not close enough in the large-amplitude vibration, the torsion spring 3 will fall into the return groove 121 from the distribution port 2124 in the large-amplitude vibration.
[0034] The torsion spring 3 after the distribution chute 2122 comes to the profiling path 213, the U-shaped structure of the profiling path 213 is large at the bottom and small at the top, the lower part can just pass the elastic part 31, and the upper part can just pass the buckling part 32, so that the torsion spring 3 with the elastic part 31 passing the distribution port 2124 can also pass the profiling path 213, and finally pass the screening to enter the discharge path 214, the anti-blocking port 2131 can effectively prevent the torsion spring 3 from being blocked at this position, and the discharge path 214 also has a U-shaped structure, and the upper end of the discharge path 214 has an inwardly extending blocking part 2141, so that the torsion spring 3 completely entering the discharge path 214 is completely limited, so that the torsion spring 3 cannot fall out of the opening of the discharge path 214, and the discharge path 214 is located at the end of the vibrator, the vibration amplitude of this position is small, and the slow movement of the torsion spring 3 can be maintained, the torsion spring 3 moves in the curved discharge path 214 and finally falls to the bottom of the discharge path 214, and the torsion spring 3 can be taken out from the bottom to facilitate subsequent workers to take and assemble.
[0035] The utility model discloses the beneficial effect lies in: through the mutual feeding groove 2112 and the back material groove 121 that tilt to the direction of the feeding roller 131, can make in it torsion spring 3 can keep being in the position of the bottom all the time, again through the feeding roller 131 in the rotation process, the torsion spring 3 is driven to the upper end of the screening groove 21 by the lifting blade 1312 on it, and falls under the action of gravity, the torsion spring 3 in the screening groove 21 will keep forward under the continuous vibration of the vibrator, finally through the step-by-step screening of single side bridge 2113, turnover groove 2121, distribution chute 2122 and profiling path 213, so that finally only the torsion spring 3 with the elastic part 31 below and the buckling part 32 above can finally enter the discharge path 214, finally complete the position conversion and screening of torsion spring 3, convenient subsequent assembly process, save a large amount of manual work.
[0036] The above embodiments are only used to illustrate the technical solutions of the utility model, and not to limit them; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
