Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1, the jig circulation line includes an upper conveyor line 10, a lower conveyor line 20, a jig lifting mechanism 30, and a jig lowering mechanism 40, both ends of the upper conveyor line 10 are shorter than the lower conveyor line 20, both ends of the upper conveyor line 10 are respectively provided with a receiving platform 50 located right above the lower conveyor line 20, and the jig lifting mechanism 30 and the jig lowering mechanism 40 drive the corresponding receiving platform 50 to lift and lower. The empty jig is conveyed to the receiving platform 50 at the tail end by the lower conveying line 20, the jig lifting mechanism 30 drives the platform to lift to be flush with the upper conveying line 10, and the external product feeding mechanism places the product in the jig for positioning. The assembly part is through material loading, pressure equipment and detection process after, unloading mechanism upwards mentions the product and separates with the tool, and empty tool moves on the terminal receiving platform 50 of upper transfer chain 10, descends mechanism's drive tool to lower floor's transfer chain 20 under the tool on, and lower floor's transfer chain 20 moves the empty tool of receiving to terminal receiving platform 50 on, and tool rising mechanism 30 drives this platform and rises and has realized the incessant automatic cycle of tool in the equipment.

The loading, press-fitting and inspection of the assembly parts are generally performed on the upper conveyor line 10, and thus the upper conveyor line 10 should have a step-by-step moving function. Referring to fig. 2, the upper conveyor line 10 includes a belt line 11 and a jig stepping feeding mechanism 12 which are arranged in a straight line, the jig stepping feeding mechanism includes a base 121, a sliding plate 122 and a translation cylinder 123, the base 121 is provided with a sliding rail, the sliding plate 122 is slidably connected to the top of the sliding rail, and the translation cylinder 123 drives the sliding plate 122 to translate back and forth along the sliding rail; the top equidistance of slide 122 is provided with the rotatable check hook 124 of array, and the check hook is installed in the slide through the pivot, and the cover is equipped with the torsional spring in the pivot. The jig with the product is pushed into the material feeding channel of the base 121, the check hook 124 hooks the clamping groove at the bottom of the jig, the translation cylinder 123 drives the sliding plate 122 to step forward for a distance, and the jig moves forward for a distance along with the sliding plate; then, the translation cylinder 123 drives the sliding plate 122 to return backwards, the jig is not left at the current position along with the movement, and the other group of check hooks 124 hooks the groove at the bottom of the jig. The belt line of the upper conveying line 10 is composed of two narrower belt lines, and the sliding plate 122 can enter between the two belt lines when stepping forward, so that the jig can be automatically fed into the belt line.

The receiving platform 50 is provided with an insertion opening on the inside. When the receiving platform 50 is at the high position, the sliding plate 122 is inserted into the receiving platform 50, the check hook 124 on the sliding plate 122 hooks the groove at the bottom of the jig, and the sliding plate 122 translates to automatically drag the jig into the upper layer conveying line 10. When the receiving platform 50 is located at the low position, the end of the lower layer conveying line 20 is inserted into the receiving platform 50, and the empty jig automatically falls onto the lower layer conveying line 20.

The belt line is provided with a plurality of sets of check hooks 124. The jig is driven to move towards the tail end by automatic operation of the belt line, after the jig is detected by a sensor on the side face of the belt line, the belt line stops, and the non-return hook 124 just hooks the groove in the bottom of the jig. Or, a positioning column is arranged in the belt line and inserted into a slotted hole at the bottom of the jig to stop the jig. If the belt line is shorter at the last station, no check hook 124 is provided in the belt line.

The side of the base 121 is provided with a stop mechanism 60 corresponding to each step pitch station, and after the sliding plate 122 is reset, the stop mechanism can prevent the jig from moving in the base 121. Referring to fig. 2, the stopping mechanism includes a sensor 61, a side pushing plate 62 and a cylinder 63, the sensor is installed in a base 121, the sensor is preferably a photoelectric sensor, a through groove is formed in the side surface of the base 121 corresponding to each step pitch station, the side pushing plate is arranged in the through groove, and the cylinder is installed on the outer side of the base 121 and used for driving the side pushing plate to move in the through groove. When the sensor detects that the jig is in place, the air cylinder 63 pushes the side push plate to be inserted into the clamping groove of the jig to fix the jig, so that the jig is effectively prevented from moving.

After the stopping mechanism pushes the jig to the other side for stopping, the jig is changed in the transverse position, and therefore the position of the jig needs to be recovered after stopping is finished, and the feeding precision of a subsequent assembly part is guaranteed. In this embodiment, a stopping mechanism 70 is disposed on the other side of the base 121 corresponding to each stopping mechanism, and the stopping mechanism resets the jig during the forward movement of the jig. Referring to fig. 3, the stopping mechanism includes a fixing seat 71 installed outside the base 121, a limiting block 72 located in a notch on a side surface of the base 121, and a limiting post 73, the limiting block is installed in the fixing seat through a rotating shaft, and the limiting block and the fixing seat are connected through an adjusting screw 74; be provided with the bar hole in the stopper, install in the spacing post of fixing base inserts in the bar hole 75. Before the jig moves, the force applied to the jig by the stop mechanism disappears, and the torsional spring on the rotating shaft drives the limiting block to reset and simultaneously resets the jig.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles described herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
