[0045] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0046] In the description of this embodiment, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this embodiment and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this embodiment.

[0047] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this embodiment, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0048] In this embodiment, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

"Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0050] The following is combined with Figures 1-5 This invention describes a nut pushing device. The nut pushing device includes: a first moving unit, multiple second moving units, and multiple pushing units.

[0051] The first moving unit is capable of moving along a first direction; multiple second moving units are respectively connected to the moving end of the first moving unit; multiple pushing units are correspondingly arranged in the second moving units. Each pushing unit includes: a conveying pipe 6, a conveying slide 8, and a pushing plate 9. One end of the conveying pipe 6 is used to receive nuts; the conveying slide 8 is connected to the other end of the conveying pipe 6; the pushing plate 9 is used to push the nuts located in the conveying slide 8 to the clamping station.

[0052] Specifically, the first moving unit can move along the first direction, thereby driving multiple second moving units and multiple pushing units to move together along the first direction. Its main function is to align with the nut-clamping mechanism through movement in the first direction.

[0053] The number of second moving units is the same as the number of pushing units, and each second moving unit corresponds one-to-one with a pushing unit. Each group of second moving units and pushing units pushes only one type of nut. In this embodiment, M4, M5, and M6 nuts are pushed; therefore, three groups of second moving units and pushing units are provided. The second moving units drive the corresponding pushing units to move along the second direction. When a nut needs to be clamped, the second moving unit drives the pushing unit to push outward to clamp the nut at the clamping station; after the nut is clamped, the second moving unit drives the pushing unit to retract in the opposite direction.

[0054] The pushing unit consists of a conveying pipe 6, a conveying slide 8, and a pushing plate 9. The conveying pipe 6 receives the screened nuts. A nut screening mechanism is arranged upstream of the conveying pipe 6 to screen nuts of corresponding specifications based on their size, shape, and other characteristics. The nut screening process is not an improvement of this invention and will not be described in detail. An air source is installed inside the conveying pipe 6 to push the nuts into the conveying slide 8. Inside the conveying slide 8, the pushing plate 9 pushes the nuts to the clamping station at the end for clamping.

[0055] Preferably, the pusher plate 9 is driven by the pusher plate 9 cylinder 7 to realize the pusher plate 9's pushing and retracting movements.

[0056] As can be seen, by configuring a first moving unit, multiple second moving units, and multiple pushing units, this utility model can realize the pushing of nuts of multiple specifications. It can be installed on the same welding machine to realize the welding process of nuts of multiple specifications, improve the welding efficiency of nuts, and reduce costs.

[0057] This utility model provides a nut pushing device, comprising: a first moving unit, multiple second moving units, and multiple pushing units. The first moving unit is movable along a first direction; multiple second moving units are respectively connected to the moving ends of the first moving unit; multiple pushing units are correspondingly arranged on the second moving units. Each pushing unit includes: a conveying pipe 6, a conveying slide 8, and a pushing plate 9. One end of the conveying pipe 6 is used to receive nuts; the conveying slide 8 is connected to the other end of the conveying pipe 6; the pushing plate 9 is used to push the nuts located in the conveying slide 8 to the clamping station. This utility model provides a nut pushing device that uses the first moving unit to drive multiple second moving units and multiple pushing units to move as a whole to align with the nut clamping mechanism; by setting multiple sets of second moving units and pushing units, when a nut needs to be clamped, the corresponding pushing unit is pushed out to realize the pushing of nuts of multiple specifications. It can be installed on the same welding machine to realize the welding process of nuts of multiple specifications, improve the nut welding efficiency, and reduce costs.

[0058] In one embodiment of this utility model, the pushing unit further includes a mounting base 10 and a magnetic suction unit 16. The mounting base 10 is disposed on the conveying slide 8 and is located close to the clamping station; the magnetic suction unit 16 is fixed on the mounting base 10 and is used to magnetically attract nuts that are close to the clamping station.

[0059] In one embodiment of the present invention, the pushing unit further includes an inclined plate 11, which is disposed on the conveying slide 8 and is located near the magnetic suction unit 16.

[0060] In the above embodiment, the mounting base 10 is fixed at the end of the conveying slide 8, which is the position of the clamping station. It is used to install the magnetic suction unit 16. The magnetic suction unit 16 can be a magnet embedded in the pressure plate 15. The nut that is close to the clamping station is attracted to the position by magnetic attraction. The pressure plate 15 is also provided with a channel for conveying the nut.

[0061] An inclined plate 11 is provided on the conveyor slide 8 near the magnetic suction unit 16, that is, near the clamping station. The nut moves to the clamping station via the inclined plate 11. If the nut is pushed out too quickly, it will fall off. If the speed is reduced, the welding efficiency will be reduced. Therefore, in this embodiment, the nut is attracted to the clamping station by the cooperation of the inclined plate 11 and the magnetic suction unit 16, thereby avoiding the problem of the nut falling off when pushed out too quickly. At the same time, the magnetic suction method is used instead of a physical limiting structure (such as a card holder), so as not to interfere with the clamping mechanism to clamp the nut.

[0062] In one embodiment of this utility model, the pushing unit further includes a first mounting plate 12 and a positioning sensor 13. The first mounting plate 12 is disposed at the fixed end of the second moving unit and is positioned close to the clamping station; the positioning sensor 13 is disposed on the first mounting plate 12 and is used to monitor whether the nut has moved into position at the clamping station.

[0063] In the above embodiment, the first mounting plate 12 is fixed to the fixed end of the second moving unit and does not move with the moving end of the second moving unit. The positioning sensor 13 is installed through the first mounting plate 12. The positioning sensor 13 monitors whether there is a nut that has moved into position at the clamping station. If there is, the second moving unit can be controlled by PLC programming to push out the pushing unit so as to clamp the nut.

[0064] In one embodiment of the present invention, the pushing unit further includes: a plate 14, a conveying slide 8 disposed on the plate 14, and a receiving cavity 84 disposed on the plate 14, wherein the pushing piece 9 is movably disposed in the receiving cavity 84.

[0065] In the above embodiment, a channel is machined in the body to form a conveying slide 8 and a receiving cavity 84. The receiving cavity 84 is used to receive the pusher piece 9, which can be pushed out or retracted from the receiving cavity 84.

[0066] In one embodiment of this utility model, the conveying slide 8 includes: a first straight slide 81, a bent slide 82, and a second straight slide 83. One end of the first straight slide 81 is connected to the conveying pipe 6; one end of the bent slide 82 is connected to the other end of the first straight slide 81; one end of the second straight slide 83 is connected to the other end of the bent slide 82, and the clamping station is located at the other end of the second straight slide 83. The receiving cavity 84 is connected to the second straight slide 83 and extends along the reverse extension line of the second straight slide 83.

[0067] In the above embodiment, the conveying slide 8 is composed of three parts connected in sequence: a first straight slide 81, a bent slide 82, and a second straight slide 83. The first straight slide 81 is connected to the conveying pipe 6, and the bent slide 82 is connected between the first straight slide 81 and the second straight slide 83. The receiving cavity 84 is located on the reverse extension line of the second straight slide 83. When the nut is conveyed to the bent slide 82, it can be pushed to the clamping station by the pusher plate 9.

[0068] In one embodiment of the present invention, the pusher 9 has an inclined surface 91 and a straight surface 92 formed at one end near the second straight slide 83. The inclined surface 91 is disposed facing the curved slide 82, and the straight surface 92 is disposed facing the second straight slide 83.

[0069] In the above embodiment, the pushing section of the pusher piece 9, that is, the end near the second straight slide rail 83, consists of an inclined surface 91 and a straight surface 92. The inclined surface 91 faces the curved slide rail 82, and the nut is guided by the inclined surface 91 and the curved slide rail 82 to move it into the second straight slide rail 83, that is, at the front end of the straight surface 92, and the nut is pushed out by the straight surface 92. By improving the structure of the pushing section of the pusher piece 9, the nut can be pushed out accurately.

[0070] In one embodiment of this utility model, the first moving unit includes an electric slide table 1 and a slide table connecting seat 2. One end of the slide table connecting seat 2 is located at the moving end of the electric slide table 1, and the other end is connected to each of the second moving units.

[0071] In the above embodiment, the movement of the electric slide table 1 is driven by the slide table connecting seat 2 to synchronously move each of the second moving units. It should be understood that the electric slide table 1 can also be replaced by other drive units.

[0072] In one embodiment of this utility model, the second moving unit includes: a second mounting plate 3, a push seat 4, and a push seat cylinder 5. The push seat 4 is disposed on the pushing unit; the moving direction of the push seat cylinder 5 is perpendicular to the moving direction of the electric slide table 1; the fixed end of the push seat cylinder 5 is connected to the slide table connecting seat 2 via the second mounting plate 3; and the moving end of the push seat cylinder 5 is connected to the pushing unit via the push seat 4.

[0073] In the above embodiment, the second mounting plate 3 is fixed to the slide connecting seat 2, and the push seat cylinder 5 is mounted through the second mounting plate 3. The movement of the push seat cylinder 5 drives the movement of the push unit through the push seat 4. The movement direction of the push seat cylinder 5 is perpendicular to that of the electric slide 1. That is, in a coordinate system established with mutually perpendicular X and Y axes in the horizontal direction, the movement direction of the push seat cylinder 5 is the Y-axis direction, and the movement direction of the electric slide 1 is the X-axis direction.

[0074] This utility model also provides a nut welding machine. The nut welding machine includes the nut pushing device described in the above embodiments of this utility model.

[0075] The nut welding machine provided by this utility model has the same advantages as described above because it includes the nut pushing device in the above embodiments of this utility model.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it.
