[0057] In order to make personnel in the art better understand the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application should belong to the scope of protection of the present application.

[0058] In this document, "illustrative" means "serving as an example, instance, or illustration," and should not necessarily be construed as preferred or advantageous over other embodiments.

[0059] Some embodiments of the present application will be described in detail with reference to the drawings. The following embodiments and features of the embodiments described below can be combined with each other in the case of no conflict between the embodiments. The steps in the following method embodiments are only used for exemplary description, and are not used to limit the present application.

[0060] In order to have a clearer understanding of the technical features, objectives and effects of the application, the specific embodiments of the present application will be described with reference to the drawings, and the same reference numerals in the drawings represent the same or similar parts or components with the same function.

[0061] In order to make the drawing simple, only the parts related to the present application are shown in the drawings, which do not represent the actual structure of the product.

[0062] Traditional automated equipment or production lines can only meet the demand of mass production, and each process of the production line needs to be equipped with a special feeding device for the process. When facing diversified and small-batch order production tasks, these systems often need to frequently change the feeding device, thereby significantly increasing the non-productive time consumption. For example, although there are equipment manufacturers on the market who have launched a flexible vibration disc feeding scheme based on industrial camera vision technology, this scheme shows a certain flexible production capacity by virtue of the ability to flexibly change materials. However, since its working principle relies on high-frequency vibration and image capture of an industrial camera, it is mainly suitable for small materials and slow-paced production environments, which limits its wider application range.

[0063] Based on various problems in the prior art described above, the material supply device provided by the embodiments of the present application adopts a modular design concept, so that it can be flexibly matched with different production process equipment, thereby constructing each production unit of the flexible production line. The material supply device of the present application is suitable for both mass production requirements and multiple small-batch production forms.

[0064] The material supply device provided by the embodiments of the present application will be described in detail below.

[0065] The material supply device provided by the embodiments of the present application includes an outer frame 10 and a material transfer mechanism 30. As shown in Figure 1 The outer frame 10 includes an electrical control cabinet 11 and a material cabinet 12, wherein the electrical control cabinet 11 is located above the material cabinet 12, and the electrical control cabinet 11 is used to place the electrical control equipment of the material supply device, including but not limited to the driving device of the material transfer mechanism 30 and the like. The electrical control cabinet 11 and the material cabinet 12 adopt an up-down layout, which not only fully utilizes the vertical space and reduces the floor area, but also facilitates operation and maintenance.

[0066] As shown in Figures 1-3As shown, the material cabinet 12 is provided with a material transfer mechanism 30 and a material storage unit 20, wherein the material storage unit 20 is located at a first end of the material cabinet 12 along a second horizontal direction 92, and the material transfer mechanism 30 is located at a second end of the material cabinet 12 along the second horizontal direction 92. The material cabinet 12 has N material storage units 20 along a first horizontal direction 91, and each material storage unit 20 has a plurality of storage positions in a vertical direction, and N is greater than or equal to 1. For example, in Figure 1 In the exemplary embodiment shown, the material cabinet 12 has two material storage units 20 along the first horizontal direction 91; in Figure 3 In the exemplary embodiment shown, the material cabinet 12 has one material storage unit 20 along the first horizontal direction 91. The material transfer mechanism 30 is used to transfer materials between the storage positions and a dispensing position, wherein the dispensing position is located on a side of the material cabinet 12 along the second horizontal direction 92 away from the material storage unit 20, and the second horizontal direction 92 is perpendicular to the first horizontal direction 91. The second side of the material cabinet 12 along the second horizontal direction 92 is provided with a feeding port 126, and the material transfer mechanism 30 completes the taking and placing of materials at the dispensing position through the feeding port 126. After the material transfer mechanism 30 takes materials or material storage containers from the material storage unit 20, it sends them to the dispensing position for subsequent processes; when the material storage containers at the dispensing position are emptied, the material transfer mechanism 30 sends them back to the material storage unit 20.

[0067] In this application, a single material supply device can be connected to a production assembly device to complete the supply of one material, or two or more material supply devices can be connected to a production assembly device to complete the supply of multiple materials.

[0068] The material supply device of the present application has strong versatility, which can be used in assembly manufacturing production sections to complete the material supply task, and can also be used in material front-end processing preparation sections to complete the material collection task.

[0069] In some embodiments, the material storage unit 20 includes a plurality of support assemblies 21 arranged in a vertical direction, and each support assembly 21 includes a plurality of support shelves 211 arranged in a first horizontal direction 91, for example Figure 4In the example embodiment shown, each support assembly 21 includes two support bars 211. The number and position of the support bars of each support assembly can be flexibly set according to the material or material storage container it carries, and is not limited herein. The material transfer mechanism 30 includes a fork 31, which is movably connected to the outer frame 10 in the vertical direction and in the second horizontal direction 92 when the material cabinet 12 has one material storage unit 20. When the material cabinet 12 has more than two material storage units 20, the fork 31 is movably connected to the outer frame 10 in the vertical direction, in the second horizontal direction 92, and in the first horizontal direction 91.

[0070] In the production process, due to the large number of parts and large quantities, in order to facilitate management and improve storage and transportation efficiency, material storage containers are usually used for storage and transportation, including but not limited to square basket containers and custom blow-molded containers. In the embodiment, each support assembly 21 includes a support bar 211 extending in the second horizontal direction 92, and the spacing between the two outermost support bars 211 matches the size of the material storage container in the first horizontal direction 91, so that the two outermost support bars 211 can support the edges of the material storage container. The design of the support bar 211 leaves space below the material storage container, which does not block the movement path of the fork 31, so that the fork 31 can move below the material storage container and lift the material storage container.

[0071] The vertically spaced support assemblies 21 not only allow the use of material storage containers with the same length and width but different heights, but also allow the three-dimensional space utilization rate of the material storage unit 20 to reach 90%, and each layer of the material storage unit 20 can place material storage containers, and empty material storage containers can also be sent back to any empty layer.

[0072] The material supply device of the embodiment has high flexibility and versatility, and can be used for feeding and discharging materials as long as the materials can be stored using material storage containers.

[0073] In some embodiments, the fork 31 is provided with a relief groove 311, and the support bar 211 is provided with a relief portion for avoiding the two ends of the fork in the first horizontal direction 91. The relief portion and the relief groove 311 of the fork 31 effectively avoid interference between the fork 31 and the support bar 211 when lifting the material storage container. Figure 4 In the example embodiment shown, each support assembly 21 includes two support bars 211, and the four corners of the fork 31 are respectively provided with a relief groove 311.

[0074] As Figure 4As shown, the four outer edges of the forks 31 are provided with stoppers 312, the positions of which are matched with the length and width dimensions of the material storage containers. When the forks 31 pick up the material storage containers, the material storage containers fall into the stoppers 312, ensuring the positional accuracy of the material storage containers on the forks 31, avoiding relative displacement between the two during the movement of the forks 31, and thus enabling the forks 31 to accurately place the material storage containers into the material taking position.

[0075] In other implementable embodiments, the material transfer mechanism 30 can also be a robot.

[0076] In some embodiments, the material supply device further comprises a material sensing device 40 for detecting whether there is material in the storage position, the material sensing device 40 being arranged at the execution terminal of the material transfer mechanism 30, and the material sensing device 40 being connected to the upper computer. For example, in the exemplary embodiment shown, the material sensing device 40 is mounted on one end of the forks 31 close to the material storage units 20. When the forks 31 move to the target picking position based on the instruction of the upper computer, the material sensing device 40 can detect whether there is a material storage container at the position and feed back to the upper computer, wherein the picking position is the position where the forks 31 are aligned with the material taking position in the vertical direction and the first horizontal direction 91. Figure 1

[0077] For example, in some embodiments, the end of the support post 211 close to the material transfer mechanism 30 is provided with a stopper 2111, as shown in Figure 4 The stopper 2111 is used to limit the displacement of the material storage container in the second horizontal direction 92. The material sensing device 40 comprises two photoelectric sensors, the height difference between the emitting ends of the two photoelectric sensors being h, which is equal to the height of the stopper 2111 on the support post 211, as shown in Figure 5 The spacing L between the emitting ends of the two photoelectric sensors along the first horizontal direction 91 is slightly smaller than the inner spacing L1 of the outermost two support posts 211 along the first horizontal direction 91.

[0078] In the production process, there is a certain probability that the material storage containers are not placed correctly on the support posts 211, such as Figure 5 the lowermost and uppermost material storage containers, one end of the material storage container being located on the support post 211 and the other end being located on the stopper 2111. In this case, when the forks 31 pick up the material storage containers, the material storage containers cannot fall exactly into the stoppers 312, and thus there will be a positional deviation during the transfer, and thus the material storage containers cannot be placed correctly into the material taking position, affecting the subsequent processes.

[0079] To solve this problem, two photoelectric sensors are used in the present embodiment: a first photoelectric sensor 41 and a second photoelectric sensor 42. As shown in​Figure 5 As shown, since the height difference between the transmitting ends of the two photoelectric sensors is equal to the height of the stop plate 2111, when the fork 31 moves to the target fork entry position based on the command from the upper level, as... Figure 5 If the material storage container is correctly positioned at fork entry position 71, both photoelectric sensors will detect its presence (1,1). If the material storage container is... Figure 5 If the lowest layer is not positioned correctly, when the forks 31 move to the fork entry position 72 based on the command from the upper level, neither the first photoelectric sensor 41 nor the second photoelectric sensor 42 will detect the material storage container (0, 0); if the material storage container is positioned incorrectly... Figure 5 If the topmost position is not placed correctly, when the fork 31 moves to the fork entry position 73 based on the instruction from the upper level, the first photoelectric sensor 41 does not detect the material storage container (0), while the second photoelectric sensor 42 detects the material storage container (1).

[0080] In this embodiment, the two photoelectric sensors can not only detect whether a material storage container exists at the target material receiving location, but also whether the material storage container is correctly placed on the support assembly 21. When it is not correctly placed, the host computer can output an alarm signal based on the feedback signal from the photoelectric sensors, thereby ensuring the safety of the material box during the transfer process and ensuring that it is accurately placed at the material dispensing position.

[0081] In some embodiments, the material cabinet 12 has a first opening 121 at a first end along the first horizontal direction 91, and a second opening 122 at the lower end of the material cabinet 12. The material storage unit 20 can enter the material cabinet 12 along the second horizontal direction 92 through the first opening 121 and the second opening 122 and be detachably connected to the material cabinet 12.

[0082] In this embodiment, the material storage unit 20 enters the material cabinet 12 through the first opening 121 and the second opening 122 and is detachably connected to the material cabinet 12. When it is necessary to replace the materials in the entire material storage unit 20, adjust the storage layout, or perform maintenance, the entire material storage unit 20 can be replaced quickly and conveniently.

[0083] In some embodiments, a safety light curtain 50 is provided at the first opening 121. The safety light curtain 50 can prevent operators from accidentally entering the material cabinet 12 and avoid the occurrence of safety accidents.

[0084] In some embodiments, the material storage unit 20 is equipped with wheels 22, which allows operators to easily move the material storage unit 20 without the aid of any means of transportation.

[0085] In some embodiments, the material storage unit 20 is configured with a docking assembly for docking with an automatic transport device, such as a forklift AGV, a back-mounted RGV, etc., so that the material storage unit 20 can be transported into the material cabinet 12 by an unmanned automatic transport device.

[0086] In some embodiments, the material cabinet 12 is configured with a magnetic attraction member 124, and the material storage unit 20 is connected to the material cabinet 12 by the magnetic attraction member 124. For example, in the exemplary embodiment shown in FIG. 1, the material cabinet 12 is configured with a magnetic attraction member 124 at the lower end of the material cabinet 12, and the material storage unit 20 is connected to the material cabinet 12 by the magnetic attraction member 124. Figure 3 In the exemplary embodiment shown, the lower end of the material cabinet 12 is provided with a crosspiece 123, which not only serves as a structural support, but also serves to limit the displacement of the material storage unit 20 in the second horizontal direction 92. The crosspiece 123 is provided with a magnetic attraction assembly, which can be a magnet, a magnetic strip, or other magnetic device, so as to generate sufficient magnetic force to attract the material storage unit 20 to the crosspiece 123.

[0087] In some embodiments, the material cabinet 12 is further provided with a guide 125. Under the action of the guide 125, the material storage unit 20 can accurately and quickly enter the corresponding position of the material cabinet 12.

[0088] In some embodiments, the outer frame 10 is further provided with a connecting assembly (not shown in the figure), which is located at the end of the outer frame 10 away from the material storage unit 20. The connecting assembly can connect the material supply device of the present application to other equipment along the second horizontal direction 92.

[0089] In some embodiments, the material supply device further comprises an interface assembly, which includes a power interface and / or a network interface, and the interface assembly is used to access the energy power or control signal of the equipment docked therewith, such as a production and assembly device.

[0090] In the present embodiment, the energy power and control signal used by the material supply device are all from the equipment docked therewith, without the need for additional access, so that additional workshop basic power facilities are not required, and the production line can be flexibly established following the equipment docked therewith.

[0091] In some embodiments, the material supply device further comprises a control assembly 60, which is arranged at the first end of the material cabinet 12 along the second horizontal direction 92 and is close to the electrical control cabinet 11. The number and position of the control assembly 60 are matched with the material storage unit 20. For example, in the exemplary embodiment shown in FIG. 1, the material cabinet 12 is provided with a control assembly 60 at the first end thereof along the second horizontal direction 92. Figure 1 and Figure 2 In the exemplary embodiment with two material storage units 20, two control assemblies 60 are arranged above the corresponding material storage units 20, respectively; in the exemplary embodiment with three material storage units 20, three control assemblies 60 are arranged above the corresponding material storage units 20, respectively. Figure 3In the exemplary embodiment of the material storage unit 20, a control assembly 60 is included. Each control assembly 60 includes at least one full vehicle replacement button 61 and one non-full vehicle replacement button 62, which are connected to the host computer.

[0092] If only some of the material storage containers in a material storage unit 20 are empty, the operator only needs to press the corresponding non-full vehicle replacement button 62 after replacing the empty containers. The host computer will receive the signal and control the material transfer mechanism 30 to move. If the material storage container is detected by the storage position material sensing device 40 at the storage position corresponding to the replaced material storage container, the host computer will mark the storage position corresponding to the replaced material storage container as full. If all the material storage containers in a material storage unit 20 need to be replaced, the operator should press the corresponding full vehicle replacement button after replacement is complete. At this time, the host computer will receive the signal and mark all the storage positions of the material storage unit 20 as full.

[0093] The material supply device of the present application can replace materials without stopping.
