[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0048] In factories with high product output demands, multiple devices of the same type are generally purchased for simultaneous production. However, manufacturers generally do not preset association plans between multiple devices of the same type, that is, they are all produced independently. In this way, each device has independent loading and unloading points, resulting in a large number of loading and unloading points, which is inconvenient for employees to perform loading and unloading operations and is cumbersome to operate.

[0049] In view of this, the present invention proposes a loading and unloading device, please refer to Figures 1 to 8 , is an embodiment of the loading and unloading device proposed in this application, and the loading and unloading device will be described in detail below in conjunction with specific drawings.

[0050] See also Figure 1 The loading and unloading device 100 includes a base 1, a loading device 2, a unloading device 3, a plurality of buffer devices 4 and a first transfer device 5. The base 1 is provided with a loading station, a buffer station and an unloading station; the loading device 2 is arranged at the loading station to provide products to be processed; the unloading device 3 is arranged at the unloading station to receive processed products; a plurality of buffer devices 4 are arranged at the buffer station, and each of the buffer devices 4 includes a first buffer fixture 41 and a second buffer fixture 42 arranged at intervals; the first transfer device 5 is movably arranged at the base 1, to transfer the products to be processed at the loading device 2 to the first buffer fixture 41, and to transfer the processed products carried on the second buffer fixture 42 to the unloading device 3.

[0051] In the technical solution of the present invention, the first transfer device 5 corresponds to one loading device 2 and one unloading device 3, but corresponds to multiple cache devices 4, and each cache device 4 corresponds to a processing device respectively. In this way, the loading and unloading device 100 can load multiple processing devices, and at the same time, the products processed by multiple processing devices can be unloaded in a centralized manner, thereby realizing the "one to many" function of the loading and unloading device 100, solving the problem that the purchased processing device is not easy to carry out structural modification, resulting in the need to set up multiple loading and unloading points for loading and unloading, which is inconvenient for employees to operate. That is, the loading and unloading device 100 proposed in this application connects multiple processing devices for loading and unloading, and there is no need to adjust the structure of the purchased processing device. Specifically, the cache device 4 includes the first cache tooling 41 and the second cache tooling 42, to correspond to the loading and unloading of the processing device. The first transfer device 5 can continuously provide the multiple first cache tooling 41 with products to be processed, and at the same time take away the processed products received by the second cache tooling 42. The first cache tooling 41 and the second cache tooling 42 can cache the products without the need for the first transfer device 5 to wait for the processing device to load and unload, thereby realizing the function of the first transfer device 5 docking with multiple cache devices 4, satisfying the "one to many" function of the loading and unloading device 100, and not affecting the processing efficiency of multiple processing devices.

[0052] Specifically, see Figure 2 In one embodiment of the specific arrangement structure of the loading device 2 and the unloading device 3, the loading device 2 includes a first assembly line 2a, and the unloading device 3 includes a second assembly line 3a. The first assembly line 2a and the second assembly line 3a are connected via a tray transfer mechanism 6. The first assembly line 2a is used to transport the tray carrying the product to be processed to the tray transfer mechanism 6. The first transfer device 5 is used to replace the product to be processed on the tray at the tray transfer mechanism with a processed product. The tray transfer mechanism 6 is used to transfer the tray to the second assembly line 3a. The second assembly line 3a is used to output the tray carrying the processed product. In this embodiment, the first assembly line 2a and the second assembly line 3a are connected by the tray transfer mechanism 6, so that after the tray transfer mechanism 6 carries the tray, the first transfer device 5 will replace the product to be processed with the processed product on the same tray, so that the second assembly line 3a does not need to return to the unloading point with an empty tray, thereby improving the utilization rate of the tray and indirectly reducing the number of trays to reduce production costs.

[0053] Also, see Figure 3In another embodiment of the specific setting structure of the loading device 2 and the unloading device 3, the loading device 2 includes a first assembly line 2a, and the unloading device 3 includes a second assembly line 3a. The first assembly line 2a and the second assembly line 3a are independently arranged, and the first assembly line 2a is used to convey the material tray of the product to be processed, and the second assembly line 3a is used to convey the material tray of the processed product. Compared with the above setting method, this setting method is that the material trays used by the loading device 2 and the unloading device 3 are also independently arranged, which can meet the situation that the material trays used for the product to be processed and the processed product are different, but there must be a situation where the material tray is empty. Based on the above two implementation methods, the specific usage scenarios are still based on actual production needs, and it is sufficient to meet the loading and unloading functions.

[0054] Also, see Figure 4 , the first transfer device 5 includes a picking mechanism 51, the picking mechanism 51 is used to pick up the products to be processed at the loading station and the processed products at the unloading station, the picking mechanism 51 includes a plurality of picking parts 511 arranged at intervals, and the spacing between at least some of the picking parts 511 is adjustable. It can be understood that the specific transfer method of the first transfer device 5 is not limited, for example, it can be transferred by supporting the product through a supporting device, or it can be transferred after being picked up by a picking device. In this embodiment, the first transfer device 5 is set as the picking mechanism 51. On this basis, the picking mechanism 51 includes a plurality of picking parts 511, which are used to pick up a plurality of products, thereby improving the transfer efficiency of the first transfer device 5. At the same time, the spacing between the picking parts 511 is adjustable, which can make the picking mechanism 51 more universal on the one hand, and can meet the needs of switching the spacing of the picking parts 511 during the transfer process, and adapting to the product spacing on different receiving tooling to meet specific needs. It is understandable that the product processing gap set on the purchased processing device is not necessarily consistent with the product placement gap on the material tray used on the loading and unloading device 100. The adjustable interval between the picking parts 511 described in this application is mainly used to switch the product spacing between the above-mentioned two receiving structures to ensure normal use.

[0055] Specifically, the picking mechanism 51 further comprises two mounting seats 512 and a driving member (not shown in the figure), wherein the two mounting seats 512 are arranged at intervals, and the picking portion 511 is mounted on the mounting seats 512; the driving member drives and connects the two mounting seats 512, and is used to adjust the distance between the two mounting seats 512, so as to adjust the spacing between the picking portions 511 located on the two mounting seats 512. There are many ways to adjust the spacing between the plurality of picking portions 511, including but not limited to arranging a driving member on each of the picking portions 511, so that each of the picking portions 511 can be movably arranged on the first transfer device 5, for example, arranging a sliding track on the first transfer device 5, and movably arranging each of the picking portions 511 on the sliding track, so that each of the picking portions 511 can move by itself, thereby adjusting the spacing between the plurality of picking portions 511, such an arrangement can meet more size spacing requirements, but obviously the structural cost and control cost are high. In this embodiment, specifically in view of the functional requirements, only the driving member is provided to drive the two mounting seats 512 to move relative to each other, so as to adjust the distance between the picking parts 511 on the two mounting seats 512 . The structure is simple, the cost is low, and the effect is good.

[0056] Furthermore, the mounting seat 512 includes a base 512a and a movable seat 512b, and the base 512a is drivingly connected to the driving member; the movable seat 512b can be movably installed on the base 512a in a direction approaching or away from another mounting seat 512, and a push member 512c is provided on the movable seat 512b, and in the direction approaching another adjacent mounting seat 512, the push member 512c is arranged beyond the base 512a, so that when the driving member drives the two bases 512a to approach each other, the push member 512c abuts against the base 512a of another mounting seat 512, so as to drive the movable seat 512b to move relative to the base 512a in a direction away from the other mounting seat 512, thereby adjusting the distance between the base 512a and the picking portion 511 on the movable seat 512b. Based on the structure in which the distance between the two mounting seats 512 can be adjusted, in this embodiment, it is also necessary to realize the distance adjustment between the multiple picking parts 511 on the mounting seat 512. There are also many specific setting methods. For example, the above-described method of independently driving the picking part 511 is described, but in this embodiment, the mounting seat 512 is split into the structure of the base 512a and the movable seat 512b, and the driving member drives and connects the two bases 512a, and the movable seat 512b can be movably installed on the base 512a, and it has an initial position close to the other mounting seat 512 and a position away from the other mounting seat 512 in its movable stroke on the base 512a. On this basis, An elastic reset member (not shown in the figure) is arranged between the movable seat 512b and the base 512a, and the elastic reset member is used to reset the movable seat 512b to the above-mentioned initial position. In addition, the movable seat 512b is also provided with the push member 512c that extends beyond the base 512a and is close to the end face of the other mounting seat 512. When the driving member drives the two bases 512a to approach each other, the push member 512c on the movable seat 512b will be pressed against the base 512a of the other mounting seat 512, thereby pushing the movable seat 512b to move relative to the base 512a away from the other mounting seat 512, that is, pushing the movable seat 512b to move from the above-mentioned initial position to the above-mentioned departure position.Based on the above structure, in this embodiment, a picking portion 511 is respectively provided on the base 512a and the movable seat 512b. When the driving member drives the two bases 512a to approach each other, the picking portions 511 on the bases 512a of the two mounting seats 512 approach each other, while the two picking portions 511 on the base 512a and the movable seat 512b on the same mounting seat 512 move away from each other, thereby satisfying the required spacing adjustment between the multiple picking portions 511, and only one driving member is required to complete the different spacing change requirements of the at least four picking portions 511. The structure is simple and clever, the cost is low, and it is more practical. The specific structural setting of the picking portion 511 is not limited here. In this embodiment, it is intended to pick up the injection molded insert at the loading device 2 and transfer the injection molded insert to the first cache tooling 41, and to pick up the injection molded parts at the second cache tooling 42, and transfer the injection molded parts to the unloading device 3. The picking portion 511 is set as an air suction structure according to the injection molded insert structure and the injection molded part structure.

[0057] In addition, the second cache tooling 42 is located above the first cache tooling 41, and a detection device is provided below the second cache tooling 42, and the detection device is used to detect the product to be processed on the first cache tooling 41. In order to avoid abnormal status during product loading, which causes the purchased processing device to process the product in abnormal status and cause equipment abnormality, the detection device is provided on the second cache tooling 42 in this embodiment, and the height of the second cache tooling 42 is set to be higher than the first cache tooling 41, so that the status of the product to be processed on the first cache tooling 41 can be detected without setting up an additional supporting structure to support the detection device, and the structural setting is ingenious and low in cost.

[0058] For further information, see Figure 5 , the second cache tooling 42 is movably arranged at the cache station, and in the movable stroke of the second cache tooling 42, the second cache tooling 42 has a material receiving position located on one side of the first cache tooling 41, a detection position corresponding to the first cache tooling 41, and a material unloading position located on the other side of the first cache tooling 41. In this embodiment, the second cache tooling 42 is set as a movable structure, on the one hand, the second cache tooling 42 can have a detection position that passes over the first cache tooling 41, so that the detection device located below the second cache tooling 42 can detect the state of the product to be processed on the first cache tooling 41, and on the other hand, the second cache tooling 42 can be moved to avoid the processing device from taking materials at the first cache tooling 41.

[0059] Also, see Figure 6, the first cache tool 41 is provided with a plurality of cache areas, each of which is provided with a plurality of cache seats 411, and the cache seats 411 are used to carry the products to be processed; the cache station is provided with a picking point corresponding to the first cache tool 41, and the first cache tool 41 can be movably provided at the cache station, so that the first cache tool 41 can movably adjust the plurality of cache areas to align with the picking points, that is, on the movable stroke of the first cache tool 41, the first cache tool 41 has a plurality of picking positions, and at each picking position, a cache area on the first cache tool 41 is aligned with the picking point. It can be understood that, for different production rhythms, the number of the cache seats 411 provided on the first cache tool 41 can be different, that is, it can be the same as the number of products picked up by the first transfer device 5 in one transfer operation, or it can be a multiple thereof, which is not specifically limited here. In this embodiment, in order to meet the needs, a plurality of cache areas are provided on the first cache fixture 41, and the number of the cache seats 411 provided in each cache area is the same as the number of products picked up by the first transfer device 5 in one transfer operation, that is, the number of the cache seats 411 provided in each cache area is the same as the number of the picking parts 511 provided on the first transfer device 5, and a plurality of cache areas are provided to cache multiple groups of products to meet the processing rhythm requirements. On this basis, in order to avoid the different positions of the plurality of cache areas, which leads to an increase in the number of pick-up and place points of the first transfer device 5 and the processing device, in this embodiment, the first cache fixture 41 is movably provided to adjust, and the plurality of cache areas correspond to the picking points respectively, thereby simplifying the control logic of the picking structure of the first transfer device 5 and the processing device, on the one hand, reducing the control cost, and on the other hand, reducing the risk of loss of control.

[0060] In addition, a lifting device corresponding to the cache seat 411 is provided at the pick-up point, and the lifting device is used to lift the product to be processed on the cache seat 411. In order to facilitate picking up the product to be processed at the pick-up point, the present embodiment further provides the lifting device at the pick-up point to lift the product to be processed on the cache seat 411 off the cache seat 411. On this basis, since the cache seat 411 is a heating base, that is, the first cache tooling 41 in this embodiment is intended to preheat the product to be processed to meet the preheating requirements of the injection molding machine product, the lifting device is also provided to prevent the product to be processed from adhering to the cache seat 411 after heating, thereby meeting the functional requirements.

[0061] Also, see Figure 7A positioning fixture 7 is also provided between the buffer station and the loading station, and the positioning fixture 7 is used to carry and position the product to be processed. In order to ensure the position accuracy of the product to be processed placed on the first buffer fixture 41, in this embodiment, the positioning fixture 7 is also provided between the loading station and the buffer station. After the first transfer device 5 picks up the product to be processed at the loading station, it is first transferred to the positioning fixture 7 for precise positioning, and then the product to be processed is picked up again at the positioning fixture 7 to complete the precise positioning of the product to be processed, thereby ensuring the accuracy of the product to be processed placed on the first buffer fixture 41.

[0062] Specifically, a positioning fixture 7 is further provided between the buffer station and the loading station, and a steering structure 71 is provided on the positioning fixture 7, and the steering structure 71 is used to adjust the direction of at least part of the products to be processed. In order to meet the processing requirements of the processing device for the products to be processed, the present embodiment provides the steering structure 71 at the positioning fixture 7 to adjust the direction of part of the products to be processed.

[0063] Also, see Figure 8 A laser engraving device 8 is also provided between the buffer station and the unloading station, and the laser engraving device 8 is used to engrave information on the processed product. In this embodiment, after the first transfer device 5 picks up the processed product from the second buffer tooling 42, it is first transferred to the laser engraving device 8, and the first transfer device 5 directly picks up the processed product for information engraving, and after the engraving is completed, the first transfer device 5 returns it to the unloading device 3 to complete the unloading.

[0064] The present invention also proposes a production system, which includes the loading and unloading device 100, multiple processing devices and multiple second transfer devices. The specific structure of the loading and unloading device 100 refers to the above embodiment. Since the production system adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Multiple processing devices are arranged corresponding to the cache device 4; each second transfer device is arranged between the corresponding cache device 4 and the processing device, and is used to transfer the products to be processed carried by the first cache tooling 41 to the processing device, and to transfer the processed products at the processing device to the second cache tooling 42. The processing device can be of various types, such as sheet metal devices, stamping devices, bending devices, injection molding devices, etc., which are not specifically limited here. In this embodiment, the processing device is an injection molding machine.
