[0070] Reference Figure 1 and Figure 2 The feeding device provided in this embodiment includes a device cabinet 100, a bearing module 200, a lifting module 300 and a pushing module 400. It should be noted that in this embodiment, the X direction, the Y direction and the Z direction are perpendicular to each other, wherein the Z direction is the vertical direction of the feeding device.

[0071] Continue to refer to Figure 1, a working position channel 110 is provided on the front side of the device cabinet 100. The working position channel 110 is in the shape of a long strip and is arranged parallel to the Y direction. The carrying module 200 includes a plurality of carriers 210 stacked in the Z direction, and the carriers 210 correspond to and carry a tray 10 one by one. The tray 10 can accommodate a card holder, and the carrier 210 can move along the X direction to extend out of the working position channel 110, so that the operator can put in the corresponding tray 10 or take the tray 10 on the carrier 210. It should be noted that the same tray 10 accommodates the same type of card holder, and different trays 10 accommodate different types of card holders, and each carrier 210 is bound with the corresponding card holder type information. In this embodiment, the card holder type information mainly includes color and size.

[0072] Preferably, in order to improve intuitiveness, a tray information mark is provided in front of each carrier 210. In the present embodiment, there are twelve carriers 210. From top to bottom along the Z direction, the tray information marks of the multiple carriers 210 are "Color1 Bin1", "Color1 Bin2", "Color1 Bin3", "Color2Bin1", "Color2 Bin2", "Color2Bin3", "Color3 Bin1", "Color3 Bin2", "Color3Bin3", "Color4 Bin1", "Color4 Bin2" and "Color4 Bin3". For example, "Color1 Bin1" corresponds to a tray of the first color and the first size, and "Color2 Bin2" corresponds to a tray of the second color and the second size.

[0073] Preferably, one material tray 10 can accommodate multiple card trays of the same type. In the present embodiment, each material tray 10 can accommodate twenty-eight card trays.

[0074] Specifically, the lifting module 300 is arranged in the device cabinet 100, and the carrying module 200 is arranged on the lifting module 300 in a height-adjustable manner in the Z direction. The lifting module 300 can drive the carrying module 200 to move to the point where the carrier 210 carrying the corresponding target type of tray faces the working position channel 110. The pushing module 400 is connected to the carrying module 200, and can push the carrier 210 facing the working position channel 110 out of the working position channel 110. Through the above arrangement, accurate identification of the mobile phone to be assembled and the corresponding tray and accurate loading of the tray can be achieved, without the need for the operator to manually identify whether the tray in the material tray 10 corresponds to the mobile phone to be assembled, which can reduce the labor intensity of the staff and improve the assembly efficiency of the mobile phone to be assembled.

[0075] More specifically, the loading device also includes a barcode scanner (not shown) and a controller (not shown) that are communicatively connected. The barcode scanner can read the type signal of the tray 10 by scanning the barcode on the tray 10, and the controller can receive the tray type signal from the barcode scanner. The bearing module 200, the lifting module 300 and the ejection module 400 are respectively communicatively connected to the controller, and the controller can determine the height position of the corresponding carrier 210 according to the received tray type signal, and thereby control the bearing module 200, the lifting module 300 and the ejection module 400 to operate, so that the carrier 210 carrying the tray of the corresponding target type extends out of the working position channel 110.

[0076] Reference Figure 2-Figure 4 The carrying module 200 further includes a mounting frame 220 and a plurality of ejection guide rails 230. The mounting frame 220 is connected to the lifting module 300 in an adjustable height in the Z direction. The plurality of ejection guide rails 230 are arranged at intervals in the Z direction and are all mounted on the mounting frame 220. The ejection guide rails 230 are arranged along the X direction. The carrier 210 is slidably arranged on the ejection guide rails 230 in a one-to-one correspondence. The mounting frame 220 provides a mounting base for the carrier 210 and can realize the integration of a plurality of carriers 210, thereby improving the compactness and integrity of the structure. The ejection guide rails 230 can realize the stable movement of the carrier 210 along the X direction.

[0077] Specifically, the mounting frame 220 includes an upper connecting plate 221 and two side connecting plates 223. The two side connecting plates 223 are arranged in parallel with each other and are spaced apart at the bottom of the upper connecting plate 221 along the Y direction. The push-out guide rails 230 are specifically provided in two groups. The two groups of push-out guide rails 230 are respectively provided on the two side connecting plates 223. In this embodiment, corresponding to the twelve carriers 210, each group is provided with twelve push-out guide rails 230, and the two sides of the carrier 210 are respectively slidably connected to the corresponding push-out guide rails 230. Through the above arrangement, the stability of each carrier 210 when moving out of the working position channel 110 along the X direction can be improved.

[0078] More specifically, refer to Figure 2 and Figure 4 The carrier 210 is provided with a receiving groove 212, in which the material tray 10 can be received, and the upper end surface of the material tray 10 is not higher than the notch of the receiving groove 212. Through the above arrangement, the material tray 10 can be placed on the carrier 210 more stably, and the problem of the carrier 210 being damaged by the collision of the tray when the carrier 210 moves along the X direction due to the upper end surface of the material tray 10 being higher than the carrier 210 can be avoided.

[0079] More specifically, refer to Figure 2 and Figure 4The upper connecting plate 221 is provided with an escape opening 222. A portion of the material tray 10 on the uppermost carrier 210 among the plurality of carriers 210 can be exposed from the escape opening 222. Through the escape opening 222, when the feeding device is disassembled for maintenance, it is convenient to clearly know whether a material tray 10 is placed on the uppermost carrier 210 among the plurality of carriers 210, so as to avoid damage to the tray on the material tray 10 when the upper connecting plate 221 is disassembled.

[0080] Reference Figure 2-Figure 5 The side connecting plate 223 is provided with a mounting support 224, and the push-out module 400 is fixedly connected to the mounting support 224. The push-out output end of the push-out module 400 can push the carrier 210 along the X direction until it extends out of the working position channel 110. In this embodiment, the push-out module 400 can specifically use a cylinder or other device as a driving end, and the push-out output end can specifically be a piston rod. The push-out module 400 is based on being able to retract and drive the carrier 210 to move, and its specific structure and type are not limited in this embodiment.

[0081] In this embodiment, only one side connecting plate 223 is provided with the mounting bracket 224, and accordingly, only one push-out module 400 is provided. In other embodiments, mounting brackets 224 may be provided on both side connecting plates 223, so that push-out modules 400 can be provided on both sides of the mounting frame 220, respectively. By using the two push-out modules 400 to operate simultaneously, the stability and reliability of the stage 210 when moving along the X direction can be improved.

[0082] Specifically, refer to Figure 3 The mounting support 224 includes a support plate and an L-shaped support seat. The support plate is fixedly arranged on the side connecting plate 223, the horizontal part of the L-shaped support seat is fixedly arranged on the support plate, and the driving end of the ejection module 400 is fixedly arranged on the vertical part of the L-shaped support seat.

[0083] More specifically, refer to Figure 3 and Figure 5 The push-out output end of the push-out module 400 is coaxially provided with a first disk and a second disk. The first disk and the second disk are spaced apart along the extension direction of the push-out output end, and an embedded annular groove 410 is formed between the first disk and the second disk. The side of the carrier 210 is provided with a first protrusion 211, and the first protrusion 211 can move into the embedded annular groove 410 along with the carrier 210 in the Z direction, so as to be positioned in the embedded annular groove 410 in the X direction, so that when the push-out output end of the push-out module 400 is extended or retracted, the carrier 210 is driven to move in the X direction.

[0084] Reference Figure 4 and Figure 6A guide rod 120 is provided on the inner side of the device cabinet 100 at one side of the working position channel 110 along the Z direction. The guide rod 120 is provided with a guide slot 121 along the length direction, and a second protrusion 213 is provided on the side of the carrier 210 away from the ejection module 400, and the second protrusion 213 is movably accommodated in the guide slot 121. The guide slot 121 can limit the second protrusion 213 during the lifting process of the carrier 210 along the Z direction, so as to prevent the carrier 210 from shaking during the lifting process, thereby ensuring the lifting stability of the carrier 210.

[0085] Specifically, the guide rod 120 is provided with an avoidance groove 122 at the position of the working position channel 110, and the avoidance groove 122 is connected to the working position channel 110 in the X direction, and the second protrusion 213 can extend out of the working position channel 110 together with the carrier 210 from the avoidance groove 122. Through the avoidance groove 122, structural interference between the groove wall of the guide through groove 121 and the second protrusion 213 can be avoided when the carrier 210 extends out of the working position channel 110.

[0086] Reference Figure 2 and Figure 7 The carrying module 200 further includes a lifting slider 240 and a support member 250. The lifting slider 240 is slidably connected to the lifting guide rail 310, and the support member 250 is fixedly connected to the lifting slider 240, and supports and is fixedly connected to the bottom of the upper connecting plate 221.

[0087] Specifically, the support member 250 is a right-angled trapezoidal frame structure. The bottom rod of the support member 250 is arranged along the Z direction and fixedly connected to the lifting slider 240. The side rod of the support member 250 is perpendicular to its bottom rod and extends along the X direction and can be fixedly connected to the bottom of the upper connecting plate 221.

[0088] Preferably, in the present embodiment, there are two support members 250 , which are parallel to each other and arranged in the middle in the Y direction, and can provide connection and support for the upper connecting plate 221 at the same time, thereby improving the connection reliability and stability of the upper connecting plate 221 .

[0089] Specifically, the lifting module 300 includes a lifting rail 310 and a lifting drive assembly 320. The lifting rail 310 is arranged in the device cabinet 100 along the Z direction. The lifting slider 240 is slidably connected to the lifting rail 310, and the lifting drive assembly 320 is transmission-connected to the lifting slider 240, and can drive the lifting slider 240 to move along the lifting rail 310. In this embodiment, the lifting drive assembly 320 can specifically select a servo motor.

[0090] More specifically, the lifting module 300 further includes a transmission screw 330. The transmission screw 330 is arranged along the Z direction, is spaced apart from the lifting guide rail 310, and is threadedly connected to and penetrates the lifting slider 240. The transmission screw 330 is connected to the rotation output end of the lifting drive assembly 320, and can rotate around its own axis driven by the lifting drive assembly 320. The lifting slider 240 can realize linear motion along the lifting guide rail 310 under the driving action of the rotation of the transmission screw 330 and the limit of the lifting guide rail 310.

[0091] More specifically, the lifting module 300 further includes a driving wheel 340, a driven wheel 350 and a transmission belt 360.
