[0046] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0047] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0048] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0049] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0050] This embodiment provides a lifting and transfer device for vertically lifting and horizontally transferring materials or jigs, pallets, bins, etc. that carry materials. It is used in conjunction with a conveyor line to realize the turnover function of materials and carriers in an automated production line.

[0051] Please refer to Figures 1-6 The lifting and transferring device includes a base box 100, a first electric roller 10, a driven roller 20, and a transfer platform 200. The first electric roller 10 and the driven roller 20 are rotatably mounted on the base box 100 and are arranged side by side with intervals. The end of the first electric roller 10 is provided with a first cam 11 that can rotate coaxially with its main body, and the end of the driven roller 20 is provided with a second cam 21 that can rotate coaxially with its main body. The first electric roller 10 and the driven roller 20 are connected by a transmission, and they can rotate synchronously at the same angular velocity, thereby enabling the first cam 11 and the second cam 21 to also rotate synchronously at the same angular velocity. The transfer platform 200 is used for horizontal material transfer. The transfer platform 200 is slidably arranged in the vertical direction on the base box 100, and the first cam 11 and the second cam 21 both push against the bottom of the transfer platform 200. The first cam 11 and the second cam 21 have the same shape and size, and their initial angles are also the same. When the first electric roller 10 starts to rotate, it drives the first cam 11 and the second cam 21 to rotate synchronously, thereby driving the transfer platform 200 to rise or fall.

[0052] For further details, please refer to Figure 1 and Figure 2 The lifting and transferring device also includes a synchronous link 30, one end of which is connected to the first cam 11 and the other end is connected to the second cam 21. The first electric roller 10 can drive the driven roller 20 to rotate synchronously with it through the synchronous link 30.

[0053] Specifically, in this embodiment, the first electric roller 10 drives the driven roller 20 to rotate synchronously via the synchronous connecting rod 30, so that the first cam 11 and the second cam 21 jointly lift the transfer platform 200, which can horizontally transfer materials. Since the first electric roller 10 has a simple structure and is a standard component, its procurement and maintenance costs are lower compared to solutions using multiple hydraulic / pneumatic lifting units. Furthermore, the first cam 11 and the second cam 21 achieve rigid mechanical linkage via the synchronous connecting rod 30, eliminating the need for multiple sensors and controllers to coordinate the actions of different components. The rotation of the first electric roller 10 naturally drives the transfer platform 200 to rise and fall smoothly, eliminating the need for a complex closed-loop control system. This not only reduces the complexity of circuit design but also lowers the failure rate and makes maintenance easier. In summary, the lifting and transfer device provided in this embodiment reduces component costs, lowers the complexity of control circuitry, has a lower failure rate, and is easier to maintain in daily operations.

[0054] For example, please refer to Figures 2-5 The lifting and transfer device also includes two lifting mounting plates 102, both of which are installed on the base box 100. The two lifting mounting plates 102 are respectively located at the two ends of the first electric roller 10 and the driven roller 20. The two ends of the first electric roller 10 and the driven roller 20 are rotatably mounted on the lifting mounting plates 102 by radial bearings such as deep groove ball bearings.

[0055] For example, to ensure the reliability of the transmission connection between the first electric roller 10 and the driven roller 20, the synchronizing link 30 is configured as a rigid structure. Please refer to [reference needed]. Figures 2-5 The synchronizing link 30 includes an integral main body 31 and two curved rod parts 32. The main body 31 extends along the interval direction between the first electric roller 10 and the driven roller 20. The two curved rod parts 32 are respectively located at both ends of the main body 31. One end of each curved rod part 32 is connected to the main body 31, and the other end is rotatably connected to the first cam 11 or the second cam 21. When the first electric roller 10 drives the first cam 11 to rotate, the synchronizing link 30 rotates around the axis of the first electric roller 10, maintaining its posture during this time. The second cam 21 and the driven roller 20 rotate synchronously with the first electric roller 10 at the same angular velocity, ensuring the synchronicity of movement. In addition, the curved rod parts 32 can avoid the structure of the first electric roller 10 and the driven roller 20 extending along the axis, which is used to connect the lifting mounting plate 102.

[0056] For example, to achieve a rotational connection between the synchronizing link 30 and the first cam 11 and the second cam 21, please refer to... Figures 2-5The first cam 11 and the second cam 21 are provided with connecting holes (not shown in the figure), and the crank part 32 is provided with a pin part 33. The pin part 33 is inserted into the connecting hole, and the pin part 33 can rotate relative to the connecting hole. This connection structure can realize the functions of rotational connection and power transmission, and is simple and reliable.

[0057] In some embodiments, the pin portion 33 may be provided on the first cam 11 and the second cam 21, and the connecting hole may be provided on the crank portion 32, which can also realize the functions of rotational connection and power transmission.

[0058] For example, to monitor the lifting status of the transfer platform 200 in real time, please refer to... Figures 2-5 The synchronous connecting rod 30 also includes a sensing part 34, which protrudes along the height direction from the side of the main body 31. The lifting and transferring device also includes a position sensor 101, which is installed in the base box 100 and is used to detect the position of the sensing part 34. Specifically, two position sensors 101 are provided, spaced apart along the length of the synchronous connecting rod 30. The horizontal position of the sensing part 34 varies depending on the rotation angle of the first electric roller 10. The two position sensors 101 can detect the sensing part 34 at the extreme positions of its reciprocating motion, corresponding to the extreme angles of clockwise and counterclockwise rotation of the first electric roller 10, which are also the fully lifted and fully lowered states of the transfer platform 200. This design cleverly and indirectly detects the lifting state of the transfer platform 200; the detection principle is simple and installation is convenient.

[0059] For example, in order to structurally limit the extreme angle of rotation of the first cam 11, please refer to Figures 2-5 The synchronous connecting rod 30 also includes a limiting part 35, which protrudes along the height direction from the side of the main body 31. The lifting mounting plate 102 has a height-limiting flange 103 located above or below the limiting part 35, used to limit the height position of the synchronous connecting rod 30. In this embodiment, the limiting part 35 protrudes along the height direction from the upper side of the main body 31, and the height-limiting flange 103 is located above the limiting part 35. When the first cam 11 rotates counterclockwise to its limit position, the upper edge of the limiting part 35 abuts against the bottom of the height-limiting flange 103; when the first cam 11 rotates clockwise to its limit position, the crank part 32 approaches or abuts against the inner bottom of the base box 100. The setting of the limiting part 35 and the height-limiting flange 103 can indirectly limit the limit angle of rotation of the first cam 11 structurally, which not only improves reliability but also simplifies the limiting structure and helps reduce equipment costs.

[0060] For example, please refer to Figure 5 The synchronous connecting rod 30 is also provided with a reinforcing rib 36. The reinforcing rib 36 is located on the outside of the main body 31 and extends in the same direction as the main body 31. This can significantly improve the structural strength of the synchronous connecting rod 30, further improve its reliability and extend its service life.

[0061] For example, please refer to Figures 1-6 The transfer platform 200 includes a transfer frame 201, a second electric roller 40, and a transfer assembly 50. The transfer frame 201 is slidably connected to the base box 100 in a vertical direction. The second electric roller 40 is rotatably mounted on the transfer frame 201 and is arranged parallel to the first electric roller 10 and the driven roller 20, effectively utilizing the space within the equipment. The transfer assembly 50 includes a transfer belt 51 and multiple transfer pulleys 52. The transfer belt 51 is sleeved on the multiple transfer pulleys 52 and the outer wall of the second electric roller 40. The outer wall of the second electric roller 40 drives the transfer belt 51 to rotate through the friction between it and the transfer belt 51. The second electric roller 40 can drive the transfer belt 51 to rotate to horizontally transfer materials.

[0062] For example, one of the base box 100 and the transfer frame 201 is provided with a plurality of guide shafts 104 extending in the vertical direction, and the other is provided with a plurality of linear bearings 203, with the plurality of guide shafts 104 correspondingly passing through the plurality of linear bearings 203. In this embodiment, please refer to Figures 1-4 Linear bearings 203 are provided at each of the four corners of the transfer frame 201, and guide shafts 104 are provided at each of the four corners of the base box 100. Through the linear sliding cooperation between the multiple guide shafts 104 and the linear bearings 203, a stable guiding effect is provided for the lifting and lowering of the transfer platform 200.

[0063] Specifically, please refer to Figures 1-6 The transfer platform 200 also includes at least two lifting rollers 202, which are rotatably mounted on the transfer frame 201 about a horizontal axis and located above the transfer frame 201. The lower end face of the lifting roller 202 abuts against the upper end face of the first cam 11 or the second cam 21. When the first electric roller 10 is working, the first cam 11 and the second cam 21 push the transfer platform 200 through their respective lifting rollers 202, converting sliding friction into rolling friction, thereby significantly reducing friction loss, making the lifting action smoother, and extending the service life.

[0064] For example, to further improve the stability of the lifting operation, please refer to... Figures 1-5 The first electric roller 10 is provided with the first cam 11 at both ends. The two first cams 11 respectively correspond to the lifting of the two lifting rollers 202 to increase the lifting action point and improve stability.

[0065] For example, to further improve the stability of the lifting operation, please refer to... Figures 1-5 The driven roller 20 is provided with the second cam 21 at both ends. The two second cams 21 respectively lift the two lifting rollers 202 to increase the lifting action point and improve stability.

[0066] For example, to improve the stability of horizontal material transfer while controlling equipment costs, please refer to... Figures 1-6 At least two transfer components 50 are arranged side-by-side, and at least two of the transfer belts 51 are connected to the second electric roller 40 for transmission. That is, one second electric roller 40 simultaneously drives at least two transfer belts 51 to rotate. By having multiple spaced transfer components 50 jointly carry the material, the area of ​​material carrying is increased, significantly improving the stability of horizontal material transfer. Furthermore, since multiple transfer components 50 share one second electric roller 40, no additional power structure is required, effectively controlling equipment costs. In this embodiment, three transfer components 50 are arranged side-by-side.

[0067] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
