Description

Technical Field

[0001] The present application relates to the technical field of automated loading and unloading production, and in particular to a loading and unloading device, loading and unloading equipment and a loading and unloading method. Background Art

[0002] With the development of 3C industry technology, the application of automated production has become increasingly common, and the loading and unloading of products has gradually tended to shift to automated loading and unloading. When loading and unloading products, in most cases, trays are used to transfer products. When loading, first use the conveyor belt to move the full tray filled with products to the loading station, then use the lifting mechanism to raise the full tray to one end of the conveyor mechanism, then use the conveyor mechanism to transfer the full tray to the unloading station, and finally use another lifting mechanism to lower the full tray for unloading to another conveyor belt.

[0003] However, in the existing loading and unloading equipment, after the conveyor belt transports the material tray to the loading station, when the lifting mechanism lifts the material tray at the loading station, or the lifting mechanism lifts the material tray down at the unloading station and places the material tray in front of the conveyor belt, only the part of the bottom of the material tray that is not in contact with the conveyor belt can be lifted up or down, and the part of the bottom of the material tray that is in contact with the conveyor belt cannot be lifted up or down. For some working conditions that require that the non-contact part of the conveyor belt cannot be contacted, it is not convenient to load and unload the product. Summary of the invention

[0043] To make the above objects, features and advantages of the present application more obvious and understandable, the following describes the detailed implementation manners of the present application with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0044] In the description of the present application, it should be understood that if terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0045] In addition, if the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0046] In this application, unless otherwise clearly defined and limited, if terms such as "installed", "connected", "joined", "fixed", etc. appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0047] In this application, unless otherwise clearly defined and limited, if there is a description such as a first feature being "on" or "under" a second feature, its meaning can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over", and "on top of" the second feature can be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature is at a higher horizontal level than the second feature. The first feature being "under", "beneath", and "underneath" the second feature can be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature is at a lower horizontal level than the second feature.

[0048] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right", and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation manner.

[0049] This application provides a loading and unloading device and a loading and unloading equipment including the loading and unloading device. The loading and unloading equipment is used to load products so that the products can be taken away by a manipulator or manually for defect detection or processing, and unload the products after the detection or processing is completed, so that the products after the detection can flow out of the production line; while the loading and unloading device is used to perform the loading or unloading of products.

[0050] Taking the loading and unloading device and the loading and unloading equipment below as an example for loading and unloading 3C (computer, communication, consumer) products, the structures of the loading and unloading device and the loading and unloading equipment in the present application will be described. It can be understood that in other embodiments, the loading and unloading device and the loading and unloading equipment of the present application are not limited to only loading and unloading 3C products, and can also be used for loading or unloading any product, which is not limited herein.

[0051] Referring to Figure 1 , Figure 1 , which shows a schematic diagram of the loading and unloading equipment 10 in an embodiment of the present application. The loading and unloading equipment 10 provided in an embodiment of the present application includes a conveying device 100 and two loading and unloading devices 200. The conveying device 100 has a loading end 101 and an unloading end 102 oppositely arranged along the first horizontal direction (the X direction shown in the figure). The two loading and unloading devices 200 are arranged at intervals along the first horizontal direction. The loading end 101 and the unloading end 102 are respectively located above the two loading and unloading devices 200. One of the loading and unloading devices 200 is located at the loading station 11, which is used to transfer the product 30 from the first height 13 to the loading end 101 of the conveying device 100. The conveying device 100 is used to transfer the product 30 from the loading end 101 to the unloading end 102. The other loading and unloading device 200 is located at the unloading station 12, which is used to move the product 30 from the unloading end 102 to the first height 13.

[0052] It can be combined with Figure 1 and Figure 2 to see that both the loading end 101 and the unloading end 102 are located at the position of the third height 15 higher than the first height 13. Therefore, one of the loading and unloading devices 200 is used to lift the product 30 from the first height 13 to the third height 15 for loading, and the other loading and unloading device 200 is used to lower the product 30 from the third height 15 to the first height 13 for unloading.

[0053] In the embodiment of the present application, the structures of the two loading and unloading devices 200 are exactly the same. Specifically, as Figure 2 shown, the loading and unloading device 200 includes a support mechanism 210 and a lifting mechanism 220. The support mechanism 210 is used to support the first support part 31 of the product 30 (as shown in Figure 3 ), so that the product 30 is located at the first height 13. The lifting mechanism 220 is arranged adjacent to the support mechanism 210. The lifting mechanism 220 is used to lift the product 30 to the third height 15 (that is, to the position of the loading end 101), or to lift and lower the product 30 from the third height 15 (that is, from the position of the unloading end 102).

[0054] It can be understood that the product 30 can be directly lifted by the lifting mechanism 220, or the product 30 can be placed in a tray and the tray can be lifted by the lifting mechanism 220. The first support portion 31 is located at the bottom of the tray, which is not limited herein.

[0055] More specifically, Figure 4 In the embodiment shown in, the support mechanism 210 includes two conveying lines 211 arranged at intervals along the first horizontal direction. Each conveying line 211 extends along the second horizontal direction perpendicular to the first horizontal direction (the Y direction shown in the figure) so that the support mechanism 210 has a starting position and a lifting position arranged adjacent to each other along the second horizontal direction. The lifting mechanism 220 is located between the two conveying lines 211 and at the lifting position; correspondingly, as Figure 3 shown, the product 30 also has two first support portions 31 arranged at intervals. Therefore, each conveying line 211 can be used to support one corresponding first support portion 31 of the product 30, so that the product 30 is located at the first height 13. In some embodiments, the conveying line 211 can be a conveying belt. Therefore, the conveying line 211 can support the first support portion 31 of the product 30 and convey the product 30 to the lifting position (above the lifting mechanism 220), and then the lifting mechanism 220 lifts the product 30 to the third height 15; or support the first support portion 31 of the product 30 and move the product 30 out of the blanking station 12.

[0056] However, as described in the background art, in the existing loading and unloading device 10, after the conveying belt conveys the tray to the loading station 11, when the lifting mechanism 220 lifts the tray at the loading station 11, or when the lifting mechanism 220 lifts the tray and descends at the unloading station 12 and places the tray in front of the conveying belt, it can only lift or lower the part of the bottom of the tray that is not in contact with the conveying belt, and cannot lift or lower the part of the bottom of the tray that is in contact with the conveying belt. For some working conditions that require no contact with non-belt contact parts, it is not convenient to load and unload the product 30.

[0057] Therefore, to solve the above problems, please continue to refer to Figure 2 and Figure 4 , in the embodiment of the present application, the loading and unloading device 200 further includes a lifting mechanism 230. The lifting mechanism 230 is at least partially adjacent to the support mechanism 210 in the first horizontal direction (that is, the projection areas of the lifting mechanism 230 and the support mechanism 210 on the horizontal plane at least partially overlap in the first horizontal direction), and it is used for the second support portion 32 of the product 30 (such as Figure 3contact as shown in [figure reference] to lift the product 30 from the first height 13 to a second height 14 that is higher than the first height 13 but lower than the third height 15, or to lower the product 30 from the second height 14 to the first height 13; wherein, as can be seen from the figure, the first support portion 31 and the second support portion 32 are perpendicular to each other and lie in the same plane.

[0058] Thus, with the above arrangement, during loading, the lifting mechanism 230 can first lift the second support portion 32 of the product 30 to disengage the product 30 from the support line and raise it to the second height 14, and then the lifting mechanism 220 contacts the first support portion 31 of the product 30 that is used to contact the support mechanism 210 to lift the product 30 from the second height 14 to the third height 15, thereby completing the loading; or the lifting mechanism 220 can first lift the first support portion 31 of the product 30 from the third height 15 to the second height 14, and then the lifting mechanism 230 supports the second support portion 32 of the product 30 to lower it from the second height 14 to the first height 13, so that the first support portion 31 of the product 30 contacts the support line, thereby completing the unloading.

[0059] Specifically, in the structure of the lifting mechanism 230, as Figure 5 shown, in one embodiment, the lifting mechanism 230 includes a first lifting cylinder 231 and a plurality of lifting members 232 connected to the first lifting cylinder 231. The plurality of lifting members 232 are spaced apart and can be lifted and lowered together under the drive of the first lifting cylinder 231; among all the lifting members 232, at least two lifting members 232 are spaced apart along the second horizontal direction, and correspondingly, the product 30 also has two second contact portions spaced apart along the second horizontal direction, so that the lifting mechanism 230 can contact the two second contact portions of the product 30 that are spaced apart.

[0060] Exemplarily, Figure 5 in the embodiment shown in [figure reference], there are three lifting members 232. One of the three lifting members 232 is spaced apart from the other two lifting members 232 in the second horizontal direction, and the remaining two lifting members 232 are spaced apart along the first horizontal direction. One of the lifting members 232 is used to contact one of the second support portions 32 of the product 30, and the other two lifting members 232 are used to contact the other second support portion 32 of the product 30. Of course, the number of lifting members 232 can be two, four, etc., as long as the lifting members 232 do not contact the portions of the product 30 other than the second contact portions.

[0061] In the structure of the lifting mechanism 220, as Figure 6In one embodiment shown, the lifting mechanism 220 includes a second lifting cylinder 221, at least two left and right telescopic cylinders 222 symmetrically arranged along the first horizontal direction, and at least two lifting plates 223 arranged oppositely along the first horizontal direction. The left and right telescopic cylinders 222 are connected to the second lifting cylinder 221, and each lifting plate 223 is connected to a corresponding left and right telescopic cylinder 222, so that the left and right telescopic cylinders 222 and all the lifting plates 223 can be lifted and lowered under the drive of the second lifting cylinder 221, and the two lifting plates 223 arranged oppositely along the first horizontal direction can approach or move away from each other along the first horizontal direction under the drive of the left and right telescopic cylinders 222. When the product 30 is separated from the support mechanism 210, the two lifting plates 223 can move away from each other and be in an open state, so as to lift the first support part 31 of the product 30 from the second height 14 to the third height 15, or lower it from the third height 15 to the second height 14.

[0062] It can be seen that during the entire feeding or discharging process, neither the support mechanism 210, the lifting mechanism 230 nor the lifting mechanism 220 contacts the middle part of the bottom of the product 30. Therefore, the technical problem of inconvenient feeding and discharging of the product 30 in some working conditions where non-belt contact parts are not allowed to be contacted is solved.

[0063] Preferably, the lifting mechanism 230 and / or the lifting mechanism 220 are located between two conveying lines 211 in the support mechanism 210. Thus, the space can be fully utilized, and the space of the feeding and discharging lifting device is relatively saved.

[0064] Furthermore, on the basis of the above embodiment, as Figure 6 shown, the lifting mechanism 230 is also set at the lifting position, and the lifting mechanism 220 is at least partially adjacent to the lifting mechanism 230 in the second horizontal direction (that is, the projection areas of the lifting mechanism 220 and the lifting mechanism 230 on the horizontal plane at least partially overlap in the second horizontal direction); preferably, the lifting mechanism 220 is arranged between two lifting members 232 spaced apart along the second horizontal direction; more preferably, the lifting mechanism 220 further includes a front and rear telescopic cylinder 224, the front and rear telescopic cylinder 224 is connected to the second lifting cylinder 221, and the left and right telescopic cylinders 222 are connected to the front and rear telescopic cylinders 224. In this way, on the premise that the second lifting cylinder 221 can lift the front and rear telescopic cylinders 224, the left and right telescopic cylinders 222 and the lifting plates 223 together, and the left and right telescopic cylinders 222 can drive the two lifting plates 223 to approach or move away from each other, the front and rear telescopic cylinders 224 can also drive the left and right telescopic cylinders 222 and the lifting plates 223 to translate together along the second horizontal direction.

[0065] As a further improvement, the area covered by the starting position of the support mechanism 210 at least partially overlaps with the area covered by the lifting position, so that the lifting mechanism 230 and the lifting mechanism 220 can be at least partially located within the area covered by the starting position, thereby saving more space in the second horizontal direction.

[0066] Thus, it can be seen that in the traditional structure, when the conveyor line 211 conveys the product 30 to move below the lifting mechanism 220, the length of the conveyor line 211 in the second horizontal direction needs to be twice the length of the product 30 in the second horizontal direction. However, by arranging the lifting mechanism 220 at the lifting position and at least partially adjacent to the lifting mechanism 230 in the second horizontal direction, and preferably making the area covered by the starting position of the support mechanism 210 at least partially overlap with the area covered by the lifting position, more preferably arranging the lifting mechanism 220 between two lifting members 232 spaced along the second horizontal direction, and / or enabling the lifting plate 223 to be controllably translated in the second horizontal direction, so that the lifting plate 223 can move closer to the starting position of the support mechanism 210, thereby making the length of the conveyor line 211 in the second horizontal direction only need to be 1.5 times or less of the length of the product 30 in the second horizontal direction, or when the product is placed on the tray, the length of the conveyor line 211 in the second horizontal direction only needs to be 1.5 times or less of the length of the tray in the second horizontal direction, thus saving more space of the loading and unloading device 200 in the second horizontal direction, and having obvious advantages under the increasing requirements of space utilization rate in the industrial site. Moreover, since the lifting plate 223 can move in the second horizontal direction, and the two lifting plates 223 arranged opposite to each other along the first direction can approach or move away from each other along the first horizontal direction, the lifting mechanism 220 can also lift products 30 of different sizes for loading or unloading, realizing the compatibility requirements for different product 30 sizes in the industrial site.

[0067] In addition, before the lifting mechanism 220 returns to the initial position while lifting the previous batch of products 30 for loading, in order to buffer the next batch of products 30 waiting for loading, as Figure 4 and Figure 5 shown, a blocking mechanism 240 is further provided between the two conveyor lines 211. The blocking mechanism 240 includes a third lifting cylinder 241 and at least one blocking block 242. In the initial state, the blocking block 242 is located below the first height 13, and the product 30 can be conveyed from one end of the conveyor line 211 to the other end of the conveyor line 211 by the conveyor line 211. When it is necessary to block the product 30, the blocking block 242 rises to a position higher than the first height 13 under the drive of the third lifting cylinder 241, so that the product 30 can be blocked by the blocking block 242 at a certain position in the middle of the conveyor line 211, thereby realizing the buffering of the next batch of products 30 waiting for loading.

[0068] Please continue to refer to Figure 1 In one embodiment, the conveying device 100 includes a material distributing mechanism 110 and a material pushing mechanism 120. The material distributing mechanism 110 includes two material distributing members 111 that are spaced apart along the second horizontal direction and can approach or move away from each other. Each material distributing member 111 extends along the first horizontal direction. Opposite ends of the material pushing mechanism 120 are respectively movably lapped on a corresponding material distributing member 111.

[0069] Combined with Figure 2 As shown, when the product 30 is transferred from the first height 13 to the third height 15 by one of the loading and unloading devices 200, the material distributing mechanism 110 starts to act. The two material distributing members 111 approach each other, and a part of each material distributing member 111 is inserted into the gap between two adjacent products 30 in a stack of products 30, so as to separate the adjacent two products 30. At this time, the material distributing member 111 supports the edge of the product 30 and can serve as a track for the movement of the product 30. One end of the material distributing member 111 is configured as a loading end 101, and the other end is configured as a unloading end 102. The material pushing mechanism 120 then pushes the product 30 to move, and the product 30 can be moved along the material distributing member 111 from the loading end 101 to the unloading end 102. After the product 30 reaches the unloading end 102, the two material distributing members 111 move away from each other again, so that the product 30 on the material distributing mechanism 110 falls onto the lifting mechanism 220.

[0070] The embodiment of the present application also provides a loading and unloading method, which can be implemented based on the loading and unloading device 10 described in the above embodiment. The steps of the loading and unloading method are introduced as follows in combination with Figures 1 to 12 :

[0071] The first step S1: Use the loading and unloading device 200 to move the product 30 from the first height 13 to the third height 15 higher than the first height 13, so as to load the product 30 onto the loading end 101 of the conveying device 100. Specifically, this step includes the following steps:

[0072] S11: Use the support mechanism 210 of the loading and unloading device 200 to support the first support part 31 of the product 30, so as to support the product 30 at the first height 13. In this step, the product 30 can be directly placed on the starting position of the conveying line 211 of the support mechanism 210 by manual, or the support mechanism 210 can be docked with an AGV (Automated Guided Vehicle), and the AGV places the product 30 on the support mechanism 210. As Figure 2 shown, before the previous stack of products 30 is loaded, first, the blocking member can extend to a position higher than the first height 13, the conveying line 211 acts, and the product 30 is conveyed to move forward along the second horizontal direction, and the next stack of products 30 waiting to be loaded is blocked and stopped on the conveying line 211; then, as Figure 7As shown, after the uppermost stack of products 30 on the lifting mechanism 220 is taken away, two lifting plates 223 on the lifting mechanism 220 that are opposite to each other in the first horizontal direction move closer to each other and descend below the first height 13; then, as Figure 8 shown, the blocking block 242 descends below the first height 13, and the conveyor line 211 continues to convey the product 30 to the lifting position at the end.

[0073] S12. Use the lifting mechanism 230 of the loading and unloading device 200 to support the second support part 32 of the product 30, and lift the product 30 from the first height 13 to the second height 14 higher than the first height 13. In this step, as Figure 9 shown, the product 30 is lifted to the second height 14 by the lifting mechanism 230, so that the product 30 is temporarily stored at the position of the second height 14. At this time, the first support part of the product 30 is separated from the conveyor line 211.

[0074] S13. Use the lifting mechanism 220 of the loading and unloading device 200 to support the first support part 31 of the product 30 at the lifting position, and lift the product 30 from the second height 14 to the third height 15 higher than the second height 14. In this step, as Figure 10 and Figure 11 shown, the lifting plates 223 of the lifting mechanism 220 rise, and the two lifting plates 223 arranged opposite to each other in the first horizontal direction move away from each other and are in an open state, so that the two lifting plates 223 can support the first support part 31 of the product 30 and rise from the second height 14 to the third height 15; at the same time, as Figure 12 shown, the blocking block 242 rises above the first height 13 again, and the next stack of products 30 is blocked and cached by the blocking block 242, completing one loading cycle.

[0075] The second step S2. Use the conveying device 100 to convey the product 30 from the loading end 101 to the unloading end 102 of the conveying device 100. In this step, as Figure 1 shown, first S21, make the two dividing parts 111 of the dividing mechanism 110 move closer to each other and insert into the gap between two adjacent products 30 to separate the uppermost product 30 from the adjacent product 30, and then S22, use the dialing mechanism 120 to dial the product 30 from the loading end 101 to the unloading end 102, and the two dividing parts 111 of the dividing mechanism 110 move away from each other again, so that the product 30 falls onto the lifting mechanism 220 of another loading and unloading device.

[0076] Step S3. Use another loading and unloading device 200 to lower the product 30 from the third height 15 to the first height 13, so as to unload the product 30 from the unloading end 102. In this step, the specific sub-steps are completely opposite to the sub-steps in step S1. Specifically, the sub-steps are as follows: S31. Use the lifting mechanism 220 of another loading and unloading device 200 to support the first support part 31 of the product 30, and lower the product 30 from the third height 15 to the second height 14; S32. After the product 30 is lowered to the second height 14, the second support part 32 of the product 30 is supported by the lifting mechanism 230 of another loading and unloading device 200. At this time, the two oppositely arranged lifting plates 223 of the lifting mechanism 220 approach and contract with each other, and descend below the first height 13. At the same time, the lifting mechanism 230 lowers the product 30 from the second height 14 to the first height 13, so as to place the product 30 on the support mechanism 210 of another loading and unloading device 200. The first contact part of the product 30 is supported by the support wire of another support mechanism 210, and finally the product 30 is output outside the device, thus completing the unloading process.

[0077] It can be seen that the loading and unloading device 200, the loading and unloading equipment 10 and the loading and unloading method of the present application realize the caching of the product 30 in a limited space, that is, reduce the equipment size and realize caching, eliminate the waiting during the feeding of the product 30, and improve the production efficiency; and different from the traditional loading and unloading device 200, it realizes that the parts of the lifting mechanism 220 and the conveyor belt supporting the product 30 are the same part, and has obvious advantages in the working conditions where it is required not to contact the non-conveyor belt contact parts for loading and unloading.

[0078] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0079] The above-described embodiments only represent several implementation manners of the present application, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
