Description

Technical Field

[0002] Car latches (such as) Figure 1 As shown, a typical car latch includes a cover plate 17 (also called a base) and a retaining ring 18 riveted to the cover plate. The structure is the same as that disclosed in patent application number 202323668970.2. When assembling this type of car latch, it is necessary to first manually place the retaining ring on the processing table in a riveting machine, then place the cover plate on the retaining ring, and let the two ends of the retaining ring pass through the corresponding holes in the cover plate, so that the two ends of the retaining ring protrude from the cover plate. Then, the riveting process is achieved by pressing down with the rivet head above the riveting machine. After the operation is completed, the riveting is manually inspected to see if it is qualified. If it is qualified, the next product is processed. If it is not qualified, it is rejected. Such operation undoubtedly increases labor costs and reduces work efficiency. Moreover, manual inspection has inspection loopholes (manual visual inspection has a high error rate). Therefore, how to design an automated riveting equipment is particularly important.

[0021] Preferably, the stamping table 504 is provided with a clamping plate 505 for positioning the cover plate. The clamping plate 505 is provided with positioning protrusions 506 that mate with two through holes on the cover plate. The pushing assembly 13 includes a transverse cylinder 131, a connecting frame 132, and a push plate 133. The transverse cylinder 131 is fixed to the bottom of the main conveying track 401. The piston rod of the transverse cylinder 131 is connected to the push plate 133. The push plate 133 is provided with a clamping opening 134 for conveying the cover plate from the cover plate feeding device 2 onto the clamping plate 505.

A spiral sleeve 708 is provided at the other end of the heating copper tubes 704. A corresponding buckle is inserted into the spiral sleeve 708. The ceramic rod 709 is aligned with its head. Below the lower pressure plate 703, a pressure rod 710 is provided, aligned with the corresponding ceramic rod 709. With this structural configuration, during operation, when the product is conveyed to the riveting station, the transverse cylinder 14 first operates, driving the spiral sleeve 708 at the front end of the heating copper tube 704 to move and align with the two ends of the retaining ring 18. Then, the high-frequency heater 16 is driven to operate, heating the heating copper tube 704. Heat is then conducted to the ceramic rod 709 via the spiral sleeve 708, and then the high-frequency riveting is activated. When the press 702 operates and presses down, it drives the lower press base 705 to move down, which in turn drives the lower press plate 703 to press down quickly.

At this time, the waste product is discharged through the waste material discharge channel 123.

[0025] like Figure 5 , Figure 6 , Figure 7 , Figure 18As shown, preferably, the buckle feeding device 1 includes a support 101, a lifting cylinder 102, and a conveying track 103. An inclined storage plate 104 is disposed within the support 101. The lifting cylinder 102 is disposed within the support 101. A positioning plate 105 is connected to the piston rod of the lifting cylinder 102. The positioning plate 105 is provided with a lifting assembly capable of lifting the buckles on the storage plate 104 to one end of the conveying track 103. The lifting assembly includes a lifting frame 107 and two parallel lifting supports 106. One or more guide ramps 108 with varying heights are provided inside 101. The lower end of the top guide ramp 108 is located above the conveyor rail 103 to slide the product into the conveyor rail 103. Two parallel lifting supports 106 are fixed on the front and rear sides of the positioning plate 105. One or more lifting frames 107 with varying heights are provided between the parallel lifting supports 106. The lowermost lifting frame 107 cooperates with the lower end of the storage plate 104. The upper surface of the lifting frame 107 is inclined and is used to guide the buckle through a guide ramp 108 at a corresponding height. 8. The fasteners 17 are conveyed to the lifting frame 107 at the next height. The specific working principle of the fastener feeding device 1 in this structure is as follows: First, the fasteners 17 are horizontally arranged in the inclined storage plate 104. Since the storage plate 104 is inclined, the bottom row of fasteners 17 will be conveyed to the lowest lifting frame 107. At this time, the driving lifting cylinder 102 works to drive the positioning plate 105 to move upward, and finally drive the multi-layered lifting frame 107 with staggered heights to move upward. When the lifting frame 107 with the fasteners 17 at the bottom is lifted to the second height, it is guided by the inclined guide plate 108 set at the second height. The buckle 17 is inclined and transported to the lifting frame 107 at the second layer height. In this way, the buckle 17 is transported layer by layer upwards and finally transported to the first conveyor track 103. Then, it is transported down the first conveyor track 103 to the flipping conveyor track 109 below. After flipping, it is transported to one end of the main conveyor track 401. The buckle 17 is then transported to the first station, namely the buckle and cover plate assembly station, by the cylinder conveying mechanism built into the side of the main conveyor track 401. It should be noted that the specific structure of the cylinder conveying mechanism built into the side of the main conveyor track 401 is conventional technology in this field and will not be described in detail.

[0026] Preferably, the output end of the conveying track 103 is connected to a flip conveying track 109 for rotating the horizontally placed buckle 90 degrees to make it vertical, ensuring that both ends of the buckle face upwards. The other end of the flip conveying track 109 is connected to one end of the main conveying mechanism 4. The flip conveying track 109 rotates the buckle 18 from a horizontal position to 90 degrees, making it easier to insert the buckle 18 into the corresponding through hole above the cover plate 1 later, further facilitating assembly.

[0027] Preferably, the structure of the cover plate feeding device 2 is the same as that of the buckle feeding device 1, and the output end of the conveying track 103 on the cover plate feeding device 2 is directly connected to the deburring device 5. Since the structure of the cover plate feeding device 2 is different from that of the buckle feeding device 1 only in conveying products, the structure of the cover plate feeding device 2 can refer to the specific structure of the buckle feeding device 1. It should be noted that since the cover plate feeding device 2 does not need to rotate the cover plate 17, the output end of the conveying track 103 on the cover plate feeding device 2 can be directly connected to the deburring device 5, and there is no need to set up a separate flipping conveying track 109.

[0028] The overall working principle of this structure is as follows: First, the cover plate 17 and the buckle 18 are automatically conveyed sequentially by the cover plate feeding device 2 and the buckle feeding device 1. The cover plate 17 is conveyed to the deburring device 5 by the pushing component 13. At this time, the deburring device 5 is driven to work, and the deburring machine 502 drives the deburring head 503 to move down to deburr the cover plate 17 on the stamping table 504. The buckle 18 is conveyed to the buckle and cover plate assembly station of the main conveying mechanism 4. After the cover plate 17 is deburred, the driving robot component 10 works, and the Y-axis slide table 10-1 drives the lifting cylinder 10-3 to move back and forth. After the double-headed cylinder 10-4 clamps on both sides, the cover plate 17 is positioned and clamped and then conveyed to the buckle and cover plate assembly station. The cover plate 17 is then placed... Assembly is performed above the buckle 18, and then the transverse cylinder 402 is driven to move the transverse plate 404 left and right. Under the action of the Y-shaped chuck 406 on one side, the assembled buckle 18 and cover plate 17 are transported to the pre-pressing station. The pre-pressing machine 602 drives the pre-pressing head 603 to press down and pre-press the product for positioning. At this time, the product that has been pre-pressed at the pre-pressing station is transported to the riveting station under the action of the conveying fixture 407. The product that has been riveted at the riveting station is transported to the inspection station under another Y-shaped chuck 406. By repeating the reciprocating motion in this way, the automatic non-stop processing operation of the product is realized, which further improves the work efficiency, eliminates the need for manual operation, and further reduces labor costs and the rate of manual error detection.

[0029] During the riveting station, the transverse cylinder 14 operates, driving the spiral sleeve 708 at the front end of the heating copper tube 704 to move and align with the two ends of the retaining ring 18. Then, the high-frequency heater 16 is driven to operate, heating the heating copper tube 704. The spiral sleeve 708 conducts heat to the ceramic rod 709. Then, the high-frequency riveting machine 702 is driven to operate and press down, driving the lower pressing seat 705 to move down. Finally, the lower pressing plate 703 is driven to press down quickly. During the pressing, under the action of the ceramic rod 709, high-frequency heating and rapid hot pressing are achieved. During the inspection station, the second lifting cylinder 802 is driven to work, which drives the two detection sensors 804 to move down and detect the riveting points corresponding to the finished products below. The control cabinet 9 makes an automatic judgment. If the product is qualified, it is directly discharged from the finished product unloading channel 11.
