Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] The structure of a reversing conveying mechanism in this embodiment is as Figures 1 to 5 shown, which includes a first conveying track section 1 and a second conveying track section 3 that are spaced apart and arranged in a straight line: a first conveying groove 11 is provided in the first conveying track section 1, and a second conveying groove 31 is provided in the second conveying track section 3; the reversing conveying mechanism further includes a reversing disc 2 and a pushing mechanism. The reversing disc 2 is adapted to flip the terminal housing 4 by 180 degrees. Specifically, the reversing disc 2 is disposed in the gap between the first conveying track section 1 and the second conveying track section 3, that is, the reversing disc 2 connects the first conveying track section 1 and the second conveying track section 2. The reversing disc 2 is driven by a rotary cylinder 5 and is adapted to rotate 180 degrees in a vertical plane. A strip-shaped conveying groove 21 penetrating along its diameter is provided at the front part of the reversing disc 2. When the first conveying groove 11, the strip-shaped conveying groove 21, and the second conveying groove 31 are spliced, they form a straight-line conveying groove to facilitate the smooth movement of the terminal housing 4. The pushing mechanism is used to push the terminal housing 4 to move in the straight-line conveying groove. When this reversing conveying mechanism is applied to an automatic assembly machine, the reversing conveying mechanism is fixed on the machine table, and an action mechanism (which belongs to the prior art and will not be elaborated in this embodiment) for assembling other components and processing (such as riveting) the terminal housing 4 is provided on the machine table.

[0022] Under the push of the pushing mechanism, the terminal housing 4 is conveyed from the upstream to the downstream in the linear conveying groove. First, the terminal housing 4 is conveyed into the first conveying groove 11, and the top end of the terminal housing 4 is processed or assembled by the action mechanism on the rotating assembly machine. Then, under the push of the pushing mechanism, the terminal housing 4 is moved into the strip-shaped conveying groove 21. When the terminal housing 4 is in the strip-shaped conveying groove 21, the reversing disc 2 is driven by the rotating cylinder 5 to rotate 180 degrees in the vertical plane, so that the terminal housing 4 is flipped with the bottom end of the terminal housing 4 facing upward. Finally, under the push of the pushing mechanism, the terminal housing 4 is pushed from the strip-shaped conveying groove 21 to the second conveying groove 31, and the bottom end of the terminal housing 4 is processed or assembled by the action mechanism on the automatic assembly machine; thus, the reversing of the terminal housing 4 is completed during the conveying process, and no manual intervention is required during this process, thereby improving the convenience of processing and being beneficial to improving the processing efficiency; moreover, the utility model can be transformed and upgraded based on the original conveying mechanism, and the transformation cost is relatively low.

[0023] As Figure 1 and Figures 3 to 5 shown, in order to prevent the terminal housing 4 from slipping in the strip-shaped conveying groove 21 when the reversing disc 2 rotates, an elastic positioning assembly for positioning the terminal housing 4 inside the strip-shaped conveying groove 21 is provided on the reversing disc 2. The terminal housing 4 is elastically pressed in the strip-shaped conveying groove 21 through the elastic positioning assembly to position the terminal housing 4, and it is also convenient to move the terminal housing 4 out of the strip-shaped conveying groove 21.

[0024] Specifically, as Figure 3 and Figure 4 shown, the elastic positioning assembly includes an elastic member 24 and a positioning block 25. The positioning block 25 is slidably installed in the chute at the center of the reversing disc 2. The chute is axially penetrated along the reversing disc 2. The rear end of the positioning block 25 is connected to the reversing disc 2 through the elastic member 24, so that the positioning block 25 is kept in a tendency to move into the strip-shaped conveying groove 21 through the elastic member 24. In this way, when the terminal housing 4 is pushed into the strip-shaped conveying groove 21, under the elastic force applied by the elastic member 24 to the positioning block 25, the front end of the positioning block 25 (i.e., the end extending into the strip-shaped conveying groove 21) presses against the side surface of the terminal housing 4 to position the terminal housing 4.

[0025] In order to limit the moving range of the positioning block 25 and prevent the positioning block 25 from slipping out of the chute, as Figure 4 and Figure 5 shown, a limiting block 251 is provided at the rear end of the positioning block 25, and the limiting block 251 is adapted to abut against the corresponding part at the rear end of the reversing disc 2 to resist and limit the positioning block 25.

[0026] In another embodiment, as Figure 4As shown, in order to optimize the structure and facilitate assembly, a slot 252 is provided on the bottom surface at the rear end of the positioning block 25. The elastic member 24 is a spring piece. One end of the elastic member 24 is inserted into the slot 252, and the other end is fixed to the commutation disc 2 by screws or welding, etc. In this way, the positioning block 25 and the elastic member 24 are quickly assembled, and the elastic member 24 is fixedly connected to the commutation disc 2.

[0027] Furthermore, as Figure 4 shown, the elastic member 24 is installed in the installation groove 23 opened at the rear part of the commutation disc 2. A positioning groove 22 is further provided at the rear part of the commutation disc 2. A connecting block 51 is fixed to the output end of the rotary cylinder 5 in the positioning groove 22, and the front end of the connecting block 51 is embedded and fixed in the positioning groove 22. The depth of the installation groove 23 is deeper than the depth of the positioning groove 22, so that the elastic member 24 has space for deformation in the installation groove 23. The connecting block 51 and the commutation disc 2 can be fixedly connected by welding or screws. Moreover, the cooperation between the connecting block 51 and the positioning groove 22 can play a positioning role during assembly. The middle part of the elastic member 24 is an arc-shaped part with an opening facing forward (that is, the opening of the arc-shaped part faces the direction of the strip-shaped conveying groove 21, that is, the opening of the arc-shaped part faces away from the connecting block 51). The arc-shaped part is adapted to abut against the front end face of the connecting block 51. In this way, the connecting block 51 can support the arc-shaped part, thereby increasing the resilience of the elastic member 24 and ensuring that the elastic member 24 exerts an effective elastic force on the positioning block 25.

[0028] In some embodiments, as Figure 1As shown, the pushing mechanism further includes a conveying substrate 6 that can move along the length direction of the linear conveying groove, a conveying air cylinder 7 for driving the movement of the conveying substrate 6, a positioning slide plate 8 installed on the conveying substrate 6 and capable of moving in the direction close to and away from the linear conveying groove, and a positioning air cylinder 9 fixed on the conveying substrate 6 for driving the movement of the positioning slide plate 8. The conveying substrate 6 is movably installed on the machine table, the conveying air cylinder 7 is fixed on the machine table, and a plurality of positioning brackets 10 are arranged at equal intervals on the positioning slide plate 8 along the length direction of the linear conveying groove. A clamping groove suitable for clamping the terminal housing 4 is provided at the end of the positioning bracket 10; when using this pushing mechanism to push the terminal housing 4 to move in the linear conveying groove, the positioning air cylinder 9 drives the positioning slide plate 8 to move towards the direction close to the linear conveying groove, the terminal housing 4 is clamped by the clamping groove on the positioning bracket 10, and then the conveying air cylinder 7 drives the conveying substrate 6 to move along the length direction of the linear conveying groove, and further drives the terminal housing 4 to move in the linear conveying groove through the positioning bracket 10, so as to realize the conveying of the terminal housing 4 and assemble relevant components or process the terminal housing 4 when the clamping groove clamps the terminal housing 4. In this way, the terminal housing 4 can be prevented from shifting. After the operation is completed, the positioning air cylinder 9 drives the positioning slide plate 8 to move away from the linear conveying groove, so that the clamping groove on the positioning bracket 10 disengages from the terminal housing 4, and finally the conveying air cylinder 7 drives the conveying substrate 6 to return to the original position for the next conveying; the terminal housing 4 can be vibrated and conveyed to the starting end of the first conveying groove 11 through a vibrating disk.
