[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] like Figure 1-4 As shown, the utility model proposes an automatic lifting assembly for a wave soldering machine, comprising a bottom box 1, a pad 2, a support roller 3, a wedge-shaped support block 4, a threaded shaft 5, and a motor 6. A pair of support rollers 3 are fixedly connected to the bottom of the pad 2, and each support roller 3 comprises a pair of bearing seats 32 fixedly connected to the bottom of the bottom box 1 by bolts and a roller body 31 rotatably connected between the two bearing seats 32. The top of the bottom box 1 is in an open state for the support roller 3 to move vertically. A pair of wedge-shaped support blocks 4 are provided and slide horizontally with the bottom plate of the bottom box 1 respectively, and the two wedge-shaped support blocks 4 are symmetrical to each other. The support roller 3 is lifted upward by the mutual approach of the two wedge-shaped support blocks 4 to realize the rise of the pad 2. When the two wedge-shaped support blocks 4 are separated from each other, the pad 2 falls back due to its own gravity. The two ends of the threaded shaft 5 are rotatably connected to the front and rear sides of the bottom box 1 respectively, and the two ends of the threaded shaft 5 are respectively threadedly engaged with the two wedge-shaped support blocks 4. The rear side of the bottom box 1 is fixedly connected with a motor 6, and the output shaft of the motor 6 is fixedly connected with the rear end of the threaded shaft 5. The panel for controlling the motor 6 can be set at a position on the wave soldering machine that is convenient for personnel to operate. When the output shaft of the motor 6 drives the threaded shaft 5 to rotate, the threaded shaft 5 can drive the two wedge-shaped support blocks 4 to move in the opposite direction as described above by screwing with the threads between the two wedge-shaped support blocks 4.

[0027] In this embodiment, the automatic lifting assembly of the wave soldering machine includes a sealing frame 9 and a sealing frame groove 10. The cross-sections of the sealing frame 9 and the sealing frame groove 10 are both in the shape of a "mouth". The sealing frame groove 10 is opened at the top of the bottom box 1, and the sealing frame 9 is detachably fixed to the bottom of the bottom box 1 by bolts. The sealing frame 9 is embedded in the sealing frame groove 10 to seal the connection between the bottom box 1 and the pad 2 to prevent foreign objects from entering the bottom box 1 or prevent fingers from accidentally entering the connection between the bottom box 1 and the pad 2 and causing pinching. And as the pad 2 rises and falls, the sealing frame 9 can move up and down in the sealing frame groove 10 and always remain in a closed state.

[0028] Furthermore, the automatic lifting assembly of the wave soldering machine also includes a guide shaft 7 and a guide shaft cylinder 8. The guide shaft 7 is fixed to the lower surface of the pad 2 near the edge, and the guide shaft cylinder 8 is fixed to the outer surface of the bottom box 1 for the guide shaft 7 to move vertically, so as to guide the pad 2 when it is lifted or lowered.

[0029] Furthermore, the automatic lifting assembly of the wave soldering machine also includes a rack 11 and a gear 12, the rack 11 is fixed to the outer wall of the bottom box 1, the gear 12 is rotatably connected to the body of the wave soldering machine, and the gear 12 is meshed with the rack 11. When the gear 12 is driven to rotate by a power device such as a motor, the device can be automatically stored in the space below the wave soldering machine or moved out therefrom. When the gear 12 is only rotatably connected to the wave soldering machine, the bottom box 1 can be manually pushed to store the device under the wave soldering machine or to be pulled out therefrom, and the friction force generated by the meshing between the gear 12 and the rack 11 can ensure a certain limit capacity, and the device will not be moved out from under the wave soldering machine.

[0030] The working principle of this embodiment is: through the vertical lifting of the pad 2, the worker's body position can be raised to adapt to the higher operating table, and the lifting of the pad 2 is mainly achieved by the translation of the two wedge-shaped support blocks 4, and no related structure is set in the vertical direction. Therefore, when the pad 2 is lowered, the height of the entire device tends to a lower level, and can be stored under the wave soldering machine to reduce space occupancy.

[0031] Specifically, the output shaft of the motor 6 drives the threaded shaft 5 to rotate, and the threaded shaft 5 drives the two wedge-shaped support blocks 4 to move in the opposite direction by screwing with the two wedge-shaped support blocks 4. When the two wedge-shaped support blocks 4 are close to each other, the two support rollers 3 can be pushed upward to make the pad 2 Figure 3 On the contrary, when the two wedge-shaped support blocks 4 move away from each other, the pad 2 and the structures thereon fall due to their own gravity.

[0032] Based on the above, during the lifting and lowering process of the backing plate 2, the sealing frame 9 moves vertically in the sealing frame groove 10, always ensuring that the bottom box 1 and the backing plate 2 are in a closed state, preventing foreign objects from entering and preventing pinching accidents.

[0033] Based on the above, the engagement between the gear 12 and the rack 11 can realize the horizontal movement of the entire device, so it can be translated and stored in the space below the wave soldering machine.

[0034] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
