Detailed Description

In order to explain technical contents and structural features of the present invention in detail, the following description is made with reference to the embodiments and the accompanying drawings.

As shown in fig. 1 and 2, the workpiece riveting apparatus 100 of the present invention is adapted to rivet a first workpiece 200 to a second workpiece 300. The first workpiece 200 is an ISOFIX supporting iron piece of a part in an infant seat, and the second workpiece 300 is a limit pin, but not limited thereto. The workpiece riveting apparatus 100 can also be adapted to process other types of workpieces according to actual processing requirements. The workpiece riveting apparatus 100 includes a conveying mechanism 10, and a workpiece detection mechanism 20 and a workpiece riveting mechanism 30 that are arranged in sequence at each location of the conveying mechanism 10 along a conveying direction of the conveying mechanism 10. The conveying mechanism 10 is provided with a plurality of positioning jigs 11 which are arranged at intervals along the conveying direction of the conveying mechanism and used for bearing the first workpiece 200 and the second workpiece 300, and the conveying mechanism 10 sequentially sends each positioning jig 11 to the workpiece detection mechanism 20 and the workpiece riveting mechanism 30. The workpiece detection mechanism 20 detects whether the first workpiece 200 and/or the second workpiece 300 are missed or misplaced in each positioning jig 11, and the workpiece riveting mechanism 30 selectively rivets the first workpiece 200 and the second workpiece 300 matched in position in each positioning jig into a whole. Therefore, the workpiece riveting equipment 100 can automatically rivet the first workpiece 200 and the second workpiece 300 into a whole, so that the labor input is reduced, the labor intensity is reduced, the automatic riveting of the first workpiece 200 and the second workpiece 300 is realized, and the processing efficiency is effectively improved. In addition, the workpiece detection mechanism 20 can detect whether the first workpiece 200 and/or the second workpiece 300 are missed or misplaced in the positioning fixture 11, and when the first workpiece 200 and/or the second workpiece 300 are detected to be missed or misplaced, the workpiece riveting device 100 is stopped in due time, the workpieces in the positioning fixture 11 are cleared, or the workpieces are correctly supplemented and adjusted, so that the situations of wrong riveting, missed riveting and the like are avoided.

It should be noted that the above-mentioned "successively order" means that after the conveying mechanism 10 first sends the positioning jig 11 to the workpiece detecting mechanism 20, the workpiece detecting mechanism 20 stops for a moment, and detects whether the workpiece is missed or not in the positioning jig 11, and whether the workpiece is dislocated or not, then the conveying mechanism 10 sends the positioning jig 11 to the workpiece riveting mechanism 30, and also stops for a moment, and the workpiece riveting mechanism 30 rivets the workpiece. Therefore, "successively" means that the conveying mechanism 10 conveys the positioning jig 11 to the workpiece detecting mechanism 20 first, and then conveys the positioning jig 11 to the workpiece riveting mechanism 30. The "order" is that the conveying mechanism 10 stops the positioning jig 11 when conveying the workpiece detecting mechanism 20 and the workpiece riveting mechanism 30. The time that the conveyor 10 is stopped can be adjusted to the processing requirements.

As shown in fig. 1 and 2, the conveying mechanism 10 is a turntable mechanism, and the workpiece detecting mechanism 20 and the workpiece riveting mechanism 30 are located outside and arranged around the turntable mechanism. This arrangement makes the workpiece riveting apparatus 100 more compact. The turntable mechanism can be an existing device, and therefore, the description is omitted. Preferably, all the positioning jigs 11 are arranged in a circle at the top of the turntable mechanism, the central angles between two adjacent positioning jigs are equal, and the positioning jigs 11 face the center of the turntable mechanism. When the turntable mechanism rotates for every angle, the turntable mechanism can sequentially send each positioning jig 11 into or out of the workpiece detection mechanism 20 and the workpiece riveting mechanism 30. The angle of each rotation of the turntable mechanism is the central angle between two adjacent positioning jigs 11. The positioning jig 11 is over against the center of the turntable mechanism, so that the positioning jig 11 is placed in a correct position when reaching the workpiece detection mechanism 20 and the workpiece riveting mechanism 30, the offset condition can not occur, and the detection or the processing is convenient. The positioning fixture 11 is provided with a positioning cavity (not labeled) for accommodating the first workpiece 200 and the second workpiece 300, and the first workpiece 200 and the second workpiece 300 can be stably positioned in the positioning fixture 11 by the positioning cavity.

Automatic blanking can be realized by the aid of the blanking mechanism 40, so that the automation degree is further improved, the labor intensity is reduced, and the processing efficiency is improved.

As shown in fig. 1 and 2, the workpiece riveting apparatus 100 of the present invention further includes a frame 50. The turntable mechanism, the workpiece detection mechanism 20, the workpiece riveting mechanism 30 and the blanking mechanism 40 are respectively arranged in the frame 50. When the workpiece riveting mechanism 30 rivets the first workpiece 200 and the second workpiece 300, due to the fact that riveting force is large, the second workpiece 300 (limiting pin) is likely to pop up due to the reasons of inaccurate placement, misplacement and the like, the rack 50 can block the limiting pin from popping up, and the production safety coefficient of equipment is improved.

It should be noted that the frame 50 is a closed frame structure, but is not limited thereto. The frame 50 of the closed frame structure is not completely closed in an absolute sense, but is provided with a protective door or the like that can be opened and closed according to actual circumstances, but is not limited thereto. After the protective door is opened, the workpiece can be loaded, the fault of the equipment can be treated, and the equipment can be cleaned. Further, the rack 50 may further include a transparent door plate, so that the processing condition inside the device can be observed conveniently through the transparent door plate.

The blanking driver 41 may use a multi-axis robot having 4, 5, or 6 axes, as required for practical use.

Further, in a preferred embodiment of the present invention, the material taking device 42 takes out the first workpiece 200 and the second workpiece 300 riveted together in the positioning fixture 11 by suction. Preferably, the material taking device 42 uses an electromagnet/magnet to suck out the first workpiece 200 and the second workpiece 300 riveted together in the positioning jig 11. Of course, the material taking device 42 may also suck out the first workpiece 200 and the second workpiece 300 riveted together in the positioning fixture 11 by using the vacuum suction head according to actual needs. In addition, in other embodiments, the material taking device 42 can take out the first workpiece 200 and the second workpiece 300 riveted together in the positioning fixture 11 by grabbing or clamping, so the manner of taking out the workpieces in the positioning fixture 11 is not limited.
