If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0033] The present application provides a material picking device, which is used to transfer materials so that the materials can be transferred from an initial position between an entrance and an exit of a storage warehouse to complete the picking, thereby enabling the materials to be quickly picked into the storage warehouse, or quickly completed out of the warehouse.

[0034] The following uses a material box as an example to illustrate the structure of the material picking device in the present application. It is understandable that in other embodiments, the material picking device of the present application is not limited to transferring only material boxes to complete picking, but can also be used to transfer any material to complete picking, which is not limited here.

[0035] Figures 1 to 4 A material picking device 10 provided in an embodiment of the present application is shown. The material picking device 10 provided in the embodiment of the present application includes a base 100, a first driving source 200, a revolution unit 300, a rotation unit 400 and a material tray 500, wherein the base 100 plays a supporting role for stabilizing the operation of the equipment; the first driving source 200 is installed on the base 100, the revolution unit 300 is connected to the first driving source 200 through a central axis 600, the rotation unit 400 is rotatably connected to the revolution unit 300 around a second axis 30 parallel to the first axis 20, and is connected to the revolution unit 300 through a transmission assembly 700; the material tray 500 is installed on the rotation unit 400 for carrying materials.

[0036] Specifically, the first driving source 200 can be a servo motor or an ordinary motor, which is used to drive the revolution unit 300 to revolve around a first axis 20 extending in the vertical direction, so as to realize the transfer of materials between an initial position (position A as shown in the figure) and the entrance and exit of the storage warehouse (position B as shown in the figure). When the material is transferred from the initial position to the entrance and exit of the storage warehouse or from the entrance and exit of the storage warehouse to the initial position, a picking is completed; in response to the revolution of the revolution unit 300, the transmission assembly 700 can drive the rotation unit 400 to rotate around the second axis 30, so as to accurately control the rotation position of the material, and then enable the material placed on the material tray 500 to complete the storage and outbound in the original posture.

[0037] Furthermore, the material tray 500 is also connected to the rotation unit 400 by rotating around a third axis 40 extending horizontally. A telescopic assembly 440 is provided on the rotation unit 400. The material tray 500 is also connected to the telescopic assembly 440. The telescopic assembly 440 is used to drive the material tray 500 to rotate around the third axis 40 relative to the rotation unit 400, so that the material tray 500 can be tilted at an angle relative to the horizontal plane, thereby controlling the angle of the material entering and exiting the storage warehouse, so that the material can be smoothly placed in the storage body entrance with a certain inclination angle to smoothly complete the loading, or can be smoothly taken out from the storage body outlet with a certain inclination angle to smoothly complete the discharging.

[0038] Exemplarily, in the embodiment shown in the figure, there are two material trays 500, and the two material trays 500 are symmetrically arranged relative to the first axis 20 in the radial direction defined by the first axis 20, so that when one of the material trays 500 is located at the entrance or exit of the storage warehouse and is ready to transport materials to the storage warehouse, the other material tray 500 is located at the initial position waiting to receive materials, thereby avoiding the waiting of the staff or the loading device at the initial position, thereby improving the picking efficiency.

[0039] It can be understood that in some other embodiments, only one material tray 500 may be provided, or multiple material trays 500 may be provided, and all material trays 500 may be symmetrically arranged in pairs relative to the first axis 20 in the radial direction defined by the first axis 20, so as to further improve the picking efficiency. The specific arrangement can be made according to needs and is not limited here.

[0040] More specifically, if Figure 3As shown, the central shaft 600 is arranged along the first axis 20 through the base 100, and one end of the central shaft 600 is connected to the first driving source 200, and the other end is fixedly connected to the revolution unit 300, and the rotation unit 400 is installed on the revolution unit 300. When the first driving source 200 is running, the first driving source 200 can drive the central shaft 600 to rotate around its own central axis (i.e., the first axis 20), and at the same time drive the revolution unit 300 to rotate around the first axis 20 to achieve revolution. In the embodiment shown in the figure, the revolution unit 300 includes a connecting plate 310 and a connecting arm bracket 320, wherein the connecting plate 310 is sleeved on one end of the central shaft 600, the connecting arm bracket 320 is connected to one end of the connecting plate 310 away from the central shaft 600, and the rotation unit 400 is rotatably connected to the connecting arm bracket 320.

[0041] In the structure of the rotation unit 400, as Figure 3 and Figure 4 As shown, the rotation unit 400 includes a rotation shaft 410 and a support plate 420. The rotation shaft 410 is arranged along the second axis 30 through the revolution unit 300, specifically through the connecting arm bracket 320 of the revolution unit 300, and the support plate 420 is fixedly connected to the top of the rotation shaft 410. The telescopic assembly 440 is arranged on the support plate 420, and the support plate 420 is also provided with a support 430 spaced apart from the telescopic assembly 440. The material tray 500 is rotatably connected to the support 430 and connected to the telescopic assembly 440 through the rotating shaft. Therefore, under the driving control of the telescopic assembly 440, the material tray 500 can rotate around the central axis of the rotating shaft (i.e., the third axis 40) by an angle, so that the material in and out angle can be controlled.

[0042] In one embodiment, the telescopic assembly 440 includes a telescopic element (not marked in the figure) and a second driving source (not marked in the figure), the telescopic element is connected to the second driving source, the material tray 500 is connected to the telescopic element, the telescopic element can change its own length (i.e., change its own telescopic stroke) by telescoping, and the second driving source can be a cylinder or an electric cylinder, etc., which is used to control the telescopic stroke of the telescopic element to control the tilt angle of the material tray 500. In this way, under the control of the second driving source, the telescopic element can be extended for a certain distance, so that one end of the material tray 500 rotates around the third axis 40 and lifts upward, and the other end of the material tray 500 rotates around the third axis 40 and descends, so that the material tray 500 can be tilted at any angle between 0° and 90°; or the telescopic element can be retracted after being extended for a certain distance, so that the material tray 500 can be reset to a horizontal state from the tilted angle, which facilitates the operation of material entry and exit, and solves the problem of having different entry and exit angles when materials are fed or unloaded from different sorting ports or storage entrances and exits.

[0043] See also Figure 3In terms of the structure of the transmission assembly 700, the transmission assembly 700 includes a first transmission wheel 710 and a second transmission wheel 720 which are connected to each other in a transmission manner. The first transmission wheel 710 is fixedly sleeved on the central shaft 600, and the second transmission wheel 720 is fixedly sleeved on the self-rotating shaft 410, so that the first transmission wheel 710 can rotate around the first axis 20 together with the central shaft 600, so as to drive the second transmission wheel 720 to rotate around the second axis 30 together with the self-rotating shaft 410. In the embodiment shown in the figure, the number of the material trays 500 is two, so the number of the self-rotating units 400 and the transmission assembly 700 is also two correspondingly. At this time, the first transmission wheels 710 of the two transmission assemblies 700 are arranged along the axial direction of the central shaft 600, so that one end of the two transmission assemblies 700 can be connected to the central shaft 600.

[0044] It can be understood that the transmission connection between the first transmission wheel 710 and the second transmission wheel 720 can be in various forms. For example, in the embodiment shown in the figure, the first transmission wheel 710 and the second transmission wheel 720 are connected by a synchronous belt transmission, that is, one end of the synchronous belt is wound around the first transmission wheel 710, and the other end is wound around the second transmission wheel 720, but the transmission connection method is not limited to this. It can also be connected by a transmission chain, or the first transmission wheel 710 and the second transmission wheel 720 are both gears, and the two are directly meshed and connected for transmission, which is not limited here.

[0045] Preferably, in one embodiment, Figure 3 As shown, the base 100 is provided with a sensing element 900, such as an infrared sensor, on one side of the radial direction defined by the first axis 20, and the revolution unit 300 is provided with a sensing element 800, such as a baffle bracket, and the sensing element 800 is specifically installed at the bottom of the revolution unit 300, so that when the revolution unit 300 revolves around the first axis 20, the sensing element 800 can be relatively oriented toward the sensing element 900 when the material tray 500 is located at the initial position (i.e., position A in the figure) or at the entrance and exit of the storage warehouse (i.e., position B in the figure), and the sensing element 900 can be triggered to emit a sensing signal when the sensing element 800 is directed toward itself, so that the material tray 500 can stop accurately at the initial position or the entrance and exit position of the storage warehouse. In this way, when the revolution unit 300 rotates 180°, that is, when the material picking device 10 completes a picking task, the sensing element 800 and the sensing element 900 are located in the same straight line, indicating that the picking position is correct, thereby being able to accurately control the position accuracy of the material picking device 10 when completing a picking task.

[0046] Optionally, the bottom wall of the tray 500 is provided with a plurality of spaced positioning posts (not shown in the figure), which are used to position the material placed in the tray 500. For example, when the material is a material box, the bottom wall of the material box is provided with a plurality of positioning holes, and the positioning posts can be inserted into the corresponding positioning holes, so that the material box can be fixed on the tray 500 to prevent the material box from moving freely relative to the tray 500 during revolution and rotation.

[0047] On the basis of the above embodiment, as a further improvement, the side walls of the material tray 500 are inclined relative to the vertical direction, and in the top-down direction, the distance between any two opposite side walls of the material tray 500 gradually decreases, so that when the material box is placed in the material tray 500, the inclined side walls can guide the material box, so that the positioning columns provided on the bottom wall of the material tray 500 can be smoothly inserted into the positioning holes opened on the material box, which helps to successfully position the material box in the material tray 500 at one time.

[0048] In addition, in order to detect whether there is material put into the material tray 500, or to weigh the material put into the material tray 500, Figure 4 As shown, a pressure sensor 1000 is further provided on the bottom wall of the tray 500. The pressure sensor 1000 is used to detect whether there is material put into the tray 500 or to weigh the material, thereby further improving the intelligence level of the material picking device 10 and facilitating the use of the user.

[0049] It can be seen that the material picking device 10 provided in the present application can not only accurately control the rotation position of the material, so that the material placed on the material tray 500 can be put into and out of the warehouse in the original position, but also solves the problem of different entry and exit angles when the material is put into or out of the warehouse from different sorting ports or storage entrances and exits, and can also ensure that the material tray 500 can be accurately positioned during revolution.

[0050] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, 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, they should be considered to be within the scope of this specification.

[0051] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
