[0044] 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.

[0045] 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.

[0046] 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, the character " / " in the present application generally indicates that the objects associated before and after are in an "and / or" relationship.

[0047] In the present application, the terms "connect", "combine", "couple", and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, direct connection refers to two parts or components being connected together without the need for an intermediate piece, and indirect connection refers to two parts or components being connected to at least one intermediate piece respectively, and the two parts or components being connected via the intermediate piece. In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings, and may include electrical connections or couplings.

[0048] 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).

[0049] In this application, it will be understood by those skilled in the art that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0050] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, the bottom can include directly below, lower left, lower right, lower front, and lower back, etc.

[0051] In this embodiment, an alternating product conveying structure is proposed, hereinafter referred to as the conveying structure, wherein the conveying structure has a receiving position for receiving products and a unloading position for outputting products, wherein the product is placed on the conveying structure by an external robot or other component, and then the product is conveyed to the unloading position, and the product is removed from the conveying structure by an external robot or other component.

[0052] Specifically, see Figure 1 The conveying structure includes a frame 1, a first bearing part 2, a second bearing part 3, a driving part 4 and an interlaced part 5. The frame 1 is arranged along a first direction and has a receiving position for receiving products and a unloading position for outputting products; the first bearing part 2 is used to carry products, the first bearing part 2 is at a first preset height, and is located at the receiving position; the second bearing part 3 is used to carry another product, the second bearing part 3 is at the unloading position, and the first bearing part 2 and the second bearing part 3 are arranged opposite to each other; the driving part 4 is arranged on the frame 1, and is used to synchronously drive the first bearing part 2 and the second bearing part 3 to alternately reciprocate between the receiving position and the unloading position; the interlaced part 5 is arranged on the frame 1, and the interlaced part 5 is connected to the first bearing part 2, so that when the first bearing part 2 and the second bearing part 3 move toward each other and pass each other, the first bearing part 2 is moved from the first preset height to the second preset height, and can be moved from the second preset height to the first preset height after the first bearing part 2 and the second bearing part 3 exchange positions.

[0053] It can be understood that the driving part 4 can synchronously drive the first load-bearing part 2 and the second load-bearing part 3 to move back and forth alternately between the material receiving position and the material unloading position, and the staggered part 5 can move the first load-bearing part 2 from the first preset height to the second preset height during the movement of the first load-bearing part 2, thereby completing the staggering between the first load-bearing part 2 and the second load-bearing part 3 to avoid interference between the first load-bearing part 2 and the second load-bearing part 3 during the conveying process. After the staggering is completed, the first load-bearing part 2 can be conveyed to the first preset height again under the action of the staggered part 5 to ensure that the products conveyed by the first load-bearing part 2 and the second load-bearing part 3 can be output from the same material unloading position, thereby reducing the space required for the unloading structure, and then reducing the occupied space of the entire conveying structure.

[0054] Exemplarily, when the first load-bearing part 2 is in the material receiving position, it can receive the product to be conveyed. At this time, the second load-bearing part 3 is in the material unloading position and can output the product. Under the action of the driving part 4, the first load-bearing part 2 can be close to the material unloading position. The first load-bearing part 2 is close to the material receiving position. The first load-bearing part 2 and the second load-bearing part 3 intersect in the middle of the frame 1. Under the action of the staggered part 5, the first load-bearing part 2 can be at a second preset height to complete the staggering. Under the continuous action of the driving part 4, the first load-bearing part 2 can exchange positions with the second load-bearing part 3. This reciprocating process can realize the continuous conveying of products by the conveying structure, thereby improving the conveying efficiency of the products.

[0055] Preferably, the first preset height is higher than the second preset height. It is understandable that the first preset height is the height of the conveying structure when outputting products, and the second preset height is the height when the first bearing part 2 avoids the second bearing part 3. If the second preset height is higher than the first preset height, when arranging the conveying structure, it is also necessary to reserve a space margin in the vertical direction for the movement of the first conveying structure. When the first preset height is higher than the second preset height, on the basis of the first preset height, there is no need to reserve additional space margin for the first bearing part 2 during the movement process, thereby making the entire conveying structure more compact, so as to further reduce the occupied space of the entire conveying structure. In addition, since the height of the first bearing part 2 is reduced during operation, the safety performance can be improved.

[0056] In this embodiment, please refer to Figure 2The first bearing part 2 includes a first moving member 21 and a first bearing member 22. The first moving member 21 is slidably disposed on the frame 1 and connected to the driving part 4. The first bearing member 22 is used to carry the product. The first bearing member 22 is disposed above the first moving member 21, and the interlaced part 5 is disposed between the first moving member 21 and the first bearing member 22 to adjust the first bearing member 22 to the first preset height or the second preset height. It can be understood that during the movement of the first bearing part 2, the height of the first moving member 21 remains unchanged. Under the action of the interlaced part 5, the height of the first bearing member 22 can be adjusted from the first preset height to the second preset height, so that the interlacing between the first bearing part 2 and the second bearing part 3 can be completed. After the interlacing is completed, the interlaced part 5 can make the first bearing part 2 at the first preset height again to complete the output of the product.

[0057] Furthermore, the first bearing part 2 further includes a guide member 23, which is disposed between the first bearing member 22 and the first moving member 21 in the vertical direction to enable the first bearing member 22 to move in the vertical direction. The guide member 23 can prevent the first bearing member 22 from shifting during the height adjustment process, thereby ensuring the conveying quality of the conveying structure.

[0058] Exemplarily, the guide member 23 is a plurality of guide rods, the length direction of which is arranged along the vertical direction and is evenly distributed around the first carrier 22, wherein one end of the guide rod is fixed to the first carrier 22, and the other end passes through the first movable member 21, and under the action of the staggered portion 5, the guide rod can be slidably connected to the first movable member 21, so that the height of the first carrier 22 can be adjusted. In addition, since the guide member 23 is arranged at the bottom of the first carrier 22, it is possible to avoid reserving space for the guide rod to move above the first carrier 22, thereby further reducing the occupied space of the conveying structure.

[0059] In this embodiment, please refer to Figure 3The interlaced portion 5 includes a height adjustment plate 51 and a support rod 52. The height adjustment plate 51 is arranged below the first bearing member 22, and a guide groove is arranged on the height adjustment plate 51; the guide groove includes a first guide groove 511, a second guide groove 512, a third guide groove 513, a fourth guide groove 514 and a fifth guide groove 515 which are arranged in sequence. The first guide groove 511 and the fifth guide groove 515 are at a third preset height, and the third guide groove 513 is at a fourth preset height. The second guide groove 512 is used to connect the first guide groove 511 and the third guide groove 513, and the fourth guide groove 514 is used to connect the third guide groove 513 and the fifth guide groove 515; the support rod 52 has one end connected to the first bearing member 22, and has a roller at the other end. The roller is slidably connected to the guide groove, and when the roller is in the first guide groove 511 or the fifth guide groove 515, the first bearing member 22 is at the first preset height, and when the roller is in the third guide groove 513, the first bearing member 22 is at the second preset height.

[0060] It can be understood that the first bearing part 2 can drive the support rod 52 to move synchronously during the movement. Since the roller is arranged in the guide groove, the roller can slide in the guide groove. In the process of the roller moving from the first guide groove 511 to the third guide groove 513 via the second guide groove 512, since the length of the support rod 52 remains unchanged, when the height of the roller changes, the height of the first bearing member 22 will change accordingly, that is, when the roller moves from the third preset height to the fourth preset height, the first bearing member 22 moves from the first preset height to the second preset height. Correspondingly, when the roller moves from the third guide groove 513 to the fifth guide groove 515 via the fourth guide groove 514, the first bearing member 22 can move from the second preset height to the first preset height. Compared with adjusting the height of the first bearing member 22 by a linear drive structure such as a cylinder, in this embodiment, with the cooperation of the support rod 52 and the support plate, no additional control system is required, thereby reducing the production cost of the conveying structure.

[0061] In this embodiment, please refer to Figure 4 The second bearing part 3 includes a second moving member 31 and a second bearing member 32 for bearing the product. The second moving member 31 is slidably disposed on the frame 1, and the second bearing member 32 is disposed on the second moving member 31, and the second bearing member 32 is at a first preset height. It can be understood that the second moving member 31 is slidably disposed on the frame 1, and the height of the second moving member 31 remains unchanged. Under the action of the driving part 4, it can slide along the first direction, and the second bearing member 32 is disposed on the second moving member 31 and is at the first preset height.

[0062] In some other possible embodiments, the distance between the second movable member 31 and the second supporting member 32 is adjustable so as to place the second supporting member 32 at different first preset heights, thereby further improving the applicability of the conveying structure.

[0063] For example, see Figure 5 The frame 1 includes a first frame 11, a second frame 12, a third frame 13 and a fourth frame 14 which are sequentially arranged in a second direction, a first moving member 21 is slidably connected to the second frame 12 and the third frame 13, a second moving member 31 is slidably connected to the first frame 11 and the fourth frame 14, and the first moving member 21 is located below the second bearing portion 3; wherein the first direction is perpendicular to the second direction, and the first direction and the second direction are as shown in FIG. Figure 1 In the direction indicated by the arrow. It can be understood that the height of the first frame 11 is consistent with that of the fourth frame 14, the height of the second frame 12 is consistent with that of the third frame 13, and the height of the second frame 12 and the third frame 13 is lower than that of the first frame 11, so as to ensure that the first carrier 22 will not interfere with the second movable member 31 during the height adjustment. In addition, such an arrangement can also make the size of the first movable member 21 smaller than that of the second movable member 31, thereby further improving the compactness of the conveying structure and reducing the occupied space of the entire conveying structure.

[0064] In addition, in order to avoid deviation between the first movable member 21 and the second movable member 31 during movement, in this embodiment, the first movable member 21 is connected to the second frame 12 and the third frame 13 via a first slider guide rail assembly 7, and the second movable member 31 is connected to the first frame 11 and the fourth frame 14 via a second slider guide rail assembly 8.

[0065] It should be noted that the connection between the first slider guide rail assembly 7 and the second slider guide rail assembly 8 is prior art, and the structure thereof is not improved in this embodiment, so it will not be described in detail here.

[0066] In this embodiment, please refer to Figure 6 The driving part 4 includes a driving motor 41, a driving wheel 42, a driven wheel 43 and a conveyor belt 44. The driving wheel 42 and the driven wheel 43 are both rotatably connected to the frame 1. The conveyor belt 44 is tensioned and wound between the driving wheel 42 and the driven wheel 43, and is located on the outside of the first bearing part 2 and the second bearing part 3. The driving motor is used to drive the driving wheel 42 to rotate; the conveyor belt 44 has an upper conveying surface 442 and a lower conveying surface 441 with opposite running directions. The first bearing part 2 is arranged on the lower conveying surface 441, and the second bearing part 3 is arranged on the upper conveying surface 442.

[0067] It is understandable that the conveyor belt 44 is arranged on the first frame 11, the first moving member 21 is arranged on the lower conveying surface 441, and the second moving member 31 is arranged on the upper conveying surface 442. Under the action of the driving motor 41 and the conveyor belt 44, the first moving member 21 and the second moving member 31 can be controlled to move in opposite directions through one drive, thereby further reducing the occupied space of the conveying structure. In addition, the conveyor belt 44 is located outside the first bearing part 2 and the second bearing part 3 to avoid the first bearing part 2 from interfering with the upper conveying surface 442 during the movement.

[0068] Exemplarily, the first bearing part 2 further includes a first connecting member 24, one end of which is connected to the first moving member 21, and the other end of which has two first clamping units, which are respectively located at the upper and lower sides of the lower conveying surface 441 to clamp the lower conveying surface 441 to ensure that the first connecting member 24 moves synchronously with the lower conveying surface 441. The second bearing part 3 further includes a second connecting member 33, one end of which is connected to the second moving member 31, and the other end of which has two second clamping units, which are respectively located at the upper and lower sides of the upper conveying surface 442 to clamp the upper conveying surface 442 to ensure that the second connecting member 33 moves synchronously with the upper conveying surface 442.

[0069] In this embodiment, the first bearing part 2 and the second bearing part 3 are both provided with a limit block 61 and a limit cylinder 62, the limit block 61 and the limit cylinder 62 are arranged at intervals, and the limit cylinder 62 is used to push the product toward the limit block 61 in one direction. It can be understood that during the transfer of the product, as the speed of the conveyor belt 44 gradually increases from zero, under the action of inertia, the product and the first bearing member 22 and the second bearing member 32 may be displaced, which may easily cause the material unloading structure to deviate from the material unloading structure and the product, so that the material unloading cannot be completed, and even damage the product. Under the action of the limit cylinder 62 and the limit block 61, the product can be limited, so that the unloading accuracy of the product can be guaranteed. In addition, under the action of the limit cylinder 62, it can be ensured that the conveying structure can convey products of different models, so as to improve the applicability of the conveying structure.

[0070] It should be noted that a limit block 61 and a limit cylinder 62 constitute a set of limit parts 6. In this embodiment, multiple sets are respectively arranged above the first bearing part 2 and the second bearing part 3, so as to further limit the displacement of the product during the transfer process.

[0071] Exemplarily, taking a square shell as an example of the transported product, there are preferably two groups of limiting portions 6, and the two groups of limiting portions 6 can clamp the shell in the length direction and the width direction respectively, so as to fix the product.

[0072] Furthermore, a limiting plate 63 is provided at the piston rod end of the limiting cylinder 62, and a buffer 64 is provided on the side of the limiting plate 63 facing the product. It can be understood that when the limiting cylinder 62 clamps the product, the limiting plate 63 is in direct contact with the product, which may cause damage to the product. The buffer 64 can prevent the limiting plate 63 from having a rigid contact with the product, thereby improving the conveying quality of the conveying structure. The buffer 64 is preferably a buffer pad.

[0073] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. 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. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
