[0003] However, most traditional lifting devices use linear cylinders to lift products, that is, vertically set linear cylinders are used to lift products out of the production line, and then the products are put back into the production line after processing. However, when traditional lifting devices are used to lift heavy products, the cylinder diameter of the linear cylinder needs to be increased accordingly. On the one hand, the large-diameter linear cylinder has a high structural height and cannot be used in the small space under the production line. On the other hand, the large-diameter linear cylinder has a high cost of use.

[0004] Therefore, the above problems need to be solved urgently. Summary of the invention

[0035] Before any embodiments of the application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the above drawings.

[0036] In this application, the terms "comprises", "includes", "has" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element.

[0037] In the present application, the term "and / or" is a description of the association relationship of associated objects, indicating that three relationships may exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump can represent: the existence of a centrifugal vortex magnetic pump alone, the existence of a centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump at the same time, and the existence of a centrifugal vortex magnetic pump alone.

In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings, and may include electrical connections or couplings.

[0039] In the present application, it will be understood by those of ordinary skill in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerances caused by manufacturing, assembly, and use associated with a specific value, and the like. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

For example, the bottom can include directly below, lower left, lower right, lower front, and lower back, etc.

[0042] See also Figures 1 to 4 , this embodiment provides a lifting device for lifting products transported on an assembly line. The lifting device includes a base 1, a lifting plate 2, a matching piece 3, a push piece 4 and a power piece 5. The base 1 is arranged below the assembly line. The lifting plate 2 is slidably arranged on the base 1 along the vertical direction, and can extend above the assembly line to lift the products on the assembly line. The matching piece 3 is arranged on the lifting plate 2. The push piece 4 is slidably arranged on the base 1 along the horizontal direction, and the push piece 4 includes an inclined surface 40 that slidably cooperates with the matching piece 3. The power piece 5 is arranged on the base 1, and the power piece 5 is configured to drive the push piece 4 to slide, so as to drive the matching piece 3 to rise and fall through the push piece 4, and the matching piece 3 drives the lifting plate 2 to rise and fall.

[0043] During lifting, the power part 5 first drives the push member 4 to slide, and the push member 4 pushes the matching part 3 through the inclined surface 40. The matching part 3 rises along the inclined surface 40 to drive the lifting plate 2 to rise. At the same time, the lifting plate 2 lifts the product on the assembly line. After the product is processed, the power part 5 drives the push member 4 to reset, and the matching part 3 and the lifting plate 2 reset synchronously, and the product is put back on the assembly line.

[0044] It can be understood that the power member 5 pushes the mating member 3 that slides with its inclined surface 40 to rise and fall through the push member 4, so that the horizontal driving force provided by the power member 5 can be converted into a vertical driving force. Compared with the method in which the power member 5 is directly vertically arranged to provide a vertical driving force, the structural height is low, so that it can be suitable for the small space under the assembly line.

[0045] It can also be understood that the power member 5 pushes the mating member 3 that slidably cooperates with its inclined surface 40 to rise and fall through the push member 4, which is more labor-saving, thereby reducing the output torque of the power member 5, and the power member 5 with a small output torque has a low cost of use.

[0046] It should be noted that the manner in which the push-pull member 4 pushes the mating member 3 that is slidably matched with its inclined surface 40 to rise and fall is mainly based on the principle of work and the principle of force decomposition in physics. Specifically, when an object is lifted along an inclined surface, gravity can be decomposed into a force component perpendicular to the inclined surface and a force component parallel to the inclined surface. The force component parallel to the inclined surface enables the object to move along the inclined surface, while the force component perpendicular to the inclined surface is used to overcome gravity. Due to the existence of the inclined surface, the force component parallel to the inclined surface is less than the force required to directly lift the object, so using the inclined surface can save effort. Among them, the key to saving effort lies in selecting a suitable inclined surface inclination angle. Specifically, the smaller the inclined surface inclination angle, the smaller the force required to lift the object, but the lifting path will increase; the larger the inclined surface inclination angle, the shorter the inclined surface, the less effort is saved, but the moving distance can be saved. Therefore, the inclination angle of the inclined surface 40 can be selected according to the actual application scenario, so it will not be repeated.

[0047] In addition, the magnitude of the friction between the matching piece 3 and the inclined surface also affects the magnitude of the effort saving, that is, the smaller the friction between the matching piece 3 and the inclined surface, the more effort is saved, and vice versa. For this reason, in this embodiment, the matching piece 3 is a roller, and the roller can roll along the inclined surface 40. In this way, the roller moves along the inclined surface 40, thereby replacing the sliding friction in the conventional structure with rolling friction, which saves more effort.

[0048] In order to improve the stability of the lifting plate 2 during lifting, a plurality of fittings 3 are provided, and the plurality of fittings 3 are distributed at the bottom of the lifting plate 2. The power member 5 is transmission-connected with the plurality of push members 4 to drive the plurality of push members 4 to slide together. The number of push members 4 corresponds to the number of fittings 3, and they correspond one to one. With such a configuration, by simultaneously pushing the bottom of the lifting plate 2 to slide by the plurality of push members 4, the lifting plate 2 can be prevented from tilting to any side during the sliding process, thereby helping to improve the stability of the lifting of the lifting plate 2 during lifting. In this embodiment, the lifting plate 2 is arranged in a rectangular shape, and four fittings 3 are provided, and the four fittings 3 are respectively arranged at the four corners of the bottom of the lifting plate 2.

[0049] Specifically, the plurality of push-pull members 4 are divided into a plurality of groups, and each group of push-pull members 4 is slidably arranged on the base 1 through a guide rail structure 41. The power member 5 is a linear cylinder, and the sliders 412 of the plurality of guide rail structures 41 are all connected to the piston rod of the linear cylinder. In the present embodiment, the four push-pull members 4 are divided into two groups, that is, two push-pull members 4 are a group, and the guide rail structure 41 is provided with two, and each guide rail structure 41 includes a slide rail 411 horizontally arranged on the base 1 and two sliders 412 slidably arranged on the slide rail 411. The four sliders 412 are connected as a whole through a connecting plate 413, and the four push-pull members 4 correspond to the four sliders 412 one by one, and the piston rod of the linear cylinder is connected to the connecting plate 413. With such an arrangement, a plurality of push-pull members 4 can be driven to slide simultaneously through a linear cylinder, and the use cost is low. Of course, in other embodiments, the power member 5 can also select any other linear drive structure, such as a linear module, an electric push rod, etc., and no specific requirements and restrictions are made on this.

[0050] In order to improve the smoothness of the sliding of the lifting plate 2, the lifting device also includes a plurality of sliding sleeves 21 vertically arranged on the base 1, each sliding sleeve 21 is adapted to be equipped with a sliding rod 22, and the plurality of sliding rods 22 are respectively connected to the bottom of the lifting plate 2. In this embodiment, four sliding sleeves 21 are provided, and four sliding rods 22 are correspondingly provided, and the four sliding rods 22 are respectively connected to the four corners of the lifting plate 2. It can be understood that the sliding friction between the sliding sleeve 21 and the sliding rod 22 is small, so that the lifting plate 2 can slide more smoothly.

[0051] Generally speaking, processing equipment for processing products will be arranged above the lifting device. If the lifting device lifts the product too high, it may cause the product to hit the processing equipment, thereby damaging the product or the processing equipment. Therefore, in order to solve the above problem, the lifting device also includes a proximity sensor 6 arranged on the base 1. The proximity sensor 6 is electrically connected to the power member 5. The proximity sensor 6 is used to detect the height position of the lifting plate 2. It can be understood that by detecting the position of the lifting plate 2 through the proximity sensor 6, the signal can be transmitted to the power member 5 when the product approaches the processing equipment, and the power member 5 stops driving the lifting plate 2 in time, thereby avoiding the collision between the product and the processing equipment. It should be noted that the type of the proximity sensor 6 is selected according to the actual application scenario, such as capacitive, photoelectric, ultrasonic, infrared, etc.

[0052] It should be pointed out that the assembly line usually conveys products continuously, which makes it difficult for the jacking mechanism to align with the product to be processed when lifting the product. Specifically, when the jacking mechanism lifts one of the products, because the assembly line continuously conveys the product, the jacking plate 2 cannot completely correspond to the product and is easily lifted to the edge of the product, resulting in the situation where the product cannot be lifted or is tilted, thereby affecting efficiency.

[0053] Therefore, in this embodiment, the lifting device further includes a first blocking member 7 and a second blocking member 8 disposed on the base 1. The first blocking member 7 and the second blocking member 8 are respectively located on both sides of the base 1 in the product conveying direction. The first blocking member 7 and the second blocking member 8 are respectively used to block two adjacent products on the assembly line. In this arrangement, the first blocking member 7 and the second blocking member 8 respectively stop the two adjacent products, so that the lifting plate 2 can more easily lift the product located upstream of the two adjacent products without touching the product located downstream of the two adjacent products.

[0054] In particular, the first blocking member 7 and the second blocking member 8 are both blocking cylinders. It can be understood that the blocking cylinder has the advantages of simple structure, reliable operation, and is not prone to failure. It should be noted that the type of blocking cylinder can be selected according to the actual application scenario, such as roller lever type, roller type, direct blocking type, horizontal type, and preferably a roller lever type blocking cylinder.

[0055] The lifting device also includes a backflow blocking member 9 arranged on the base 1, and the backflow blocking member 9 is used to prevent the backflow of the product on the lifting plate 2. Such a configuration can avoid the backflow of the product when the lifting plate 2 lifts the product, and can ensure the normal lifting action. The backflow blocking member 9 is preferably a blocker, which is a backflow blocking member commonly used on the assembly line, usually driven by a pneumatic element, which can limit the movement of the product and prevent it from flowing back. Common blockers include single-wheel / double-wheel vertical pneumatic elements, spring hydraulic limiters, etc. In other embodiments, any structure in the prior art that can achieve one-way limiting can also be selected, so it will not be repeated.

[0056] This embodiment further provides a production line, including the above-mentioned lifting device and an assembly line, the assembly line is used to transport products, and the lifting device is used to lift the products transported by the assembly line. It can be understood that the production line including the above-mentioned lifting device has low use cost.

For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
