Then, the rotary drive mechanism 203 is reset, and the fourth cylinder drives the riveting device 2 to move upward to the original position. Finally, the motor of the second conveying mechanism 5 resumes operation. The working sequence of the motors of the fourth cylinder, the fifth cylinder 205, the sixth cylinder 206 and the first conveying mechanism 4 can be controlled by the existing control program in coordination with the time difference sequence of the fifth detector 85, or by the control module in coordination with the fourth detector 84 and multiple limit sensors (such as multiple optical fiber sensors, multiple proximity switches, etc.) to perform sequential work at the time of triggering. The working mode of the above-mentioned mechanical components can be controlled by the existing electrical component control method. These control methods are all conventional technical means in the field of electrical control, and are not the innovation of the present invention. The innovation of the present invention lies in the use of mechanical automation to replace the traditional manual method to assemble and produce the temperature sensing device.

[0051] In one embodiment, there is no need to set the fifth detector 85 on the second conveying mechanism 5. The second conveying mechanism 5 is designed so that when the fourth sensor is triggered, an assembly jig 51 of the second conveying mechanism 5 is located on the active track of the feeding flipping device 1, and the other assembly jig 51 is located below the riveting device 2. This arrangement can reduce the number of detectors used and effectively reduce costs.

[0052] See also Figures 8 to 10 In one embodiment, a guide protrusion 232 is provided on the top of the slider 23, and the guide structure is a centripetal arc sliding hole 241 provided on the guide plate 24 with the processing hole 211 as the center, and the guide protrusion 232 is located in the sliding hole 241; through such a setting, the slider 23 is driven to reciprocate through the guide structure of the guide plate 24, and the setting is ingenious.

[0053] In one embodiment, the rotating member 22 is hollow, and a driving seat 25 is provided on the inner circumference of the rotating member 22. Preferably, the rotating member 22 and the driving seat 25 are an integrated structure to facilitate product manufacturing. The inner circumference of the driving seat 25 corresponds to the slider 23 and is provided with an eccentric arc avoidance groove 251 centered on the processing hole 211. The sum of the maximum depth of the arc avoidance groove 251 and the length of the slide groove 212 is equal to the length of the slider 23. Through such a setting, the driving seat 25 has an avoidance space when the slider 23 is reset, and the inner side wall of the arc avoidance groove 251 forms a driving surface to drive the slider 23 to slide, so that the slider 23 slides more smoothly.

[0054] In one embodiment, a rolling bearing 233 is provided at the end of the slider 23 corresponding to the inner wall of the arc avoidance groove 251; by such a configuration, friction loss between the slider 23 and the inner wall of the arc avoidance groove 251 is avoided, thereby improving product reliability.

[0055] In one embodiment, four sliders 23 and four slide grooves 212 are provided correspondingly, and in one embodiment, they are arranged at equal angles in the riveting seat 21; by such an arrangement, the riveting effect of the workpiece is good.

[0056] In one embodiment, the riveted seat 21 is provided with a plurality of fixed blocks 213, the slide groove 212 is formed between the fixed blocks 213, and also includes a cover body 26, the top of the cover body 26 is connected to the bottom of the bracket 204, the guide plate 24 is a hollow ring, and a circular positioning portion 261 is provided at the bottom of the cover body 26 corresponding to the inner circle of the guide plate 24, the positioning portion 261 passes through the inner circle of the guide plate 24 and is fixedly connected to the fixed block 213 of the riveted seat 21, and the connection method is, for example, screw connection; through such a setting, the assembly of the cover body 26 and the riveted seat 21 enables the guide plate 24 to be clamped between the two, thereby simplifying the assembly process.

[0057] See also Figure 2 In one embodiment, the conveyor belt of the second conveying mechanism 5 is fixedly arranged with a plurality of the assembly jigs 51; the output end of the second conveying mechanism 5 is provided with a blanking plate 53 with an arc-shaped outer end, and the end radius of the blanking plate 53 gradually increases from one end to the other end of the second conveying mechanism 5. When the assembly jig 51 moves to the output end of the second conveying mechanism 5, the temperature sensing device at the upper end of the assembly jig 51 will slide along the edge of the blanking plate 53, thereby gradually increasing the distance from the upper end of the assembly jig 51, and finally completing the unloading; through such a setting, automatic unloading is achieved through the blanking plate 53, which is convenient to use.
