[0013] Preferably, both ends of the receiving rod are provided with material plate limiting protrusions, which are used to limit the position of the material plate in the first direction.

[0014] Preferably, a feeding limit strip is installed around the four sides of the upper surface of the material support plate, and the four feeding limit strips together limit the material tray to be positioned on the material support plate. The installation position of the feeding limit strips is adjustable.

[0036] The feeding device provided by this utility model places multiple layers of support plates in the hopper assembly. These support plates support the material tray. During feeding, the feeding and transfer drive assembly drives the feeding and transfer plates to extend into the hopper assembly. When the feeding and transfer plates extend below the support plates corresponding to their height, the hopper lifting assembly moves the support plates downwards, allowing them to be supported by the feeding and transfer plates. The support plates then detach from the support of the hopper assembly. The feeding and transfer drive assembly then retracts the feeding and transfer plates to detach from the hopper assembly, allowing the material removal structure to retrieve the material from the tray. After all materials have been loaded, the loading and transfer drive assembly moves the loading and transfer plate to place the empty trays and support plates back into the hopper assembly. Subsequently, the loading and transfer drive assembly retracts the loading and transfer plate outside the hopper assembly. The hopper lifting assembly then raises and lowers the hopper assembly, moving the trays and support plates of the next or previous layer containing materials to the height of the corresponding loading and transfer plate. The hopper lifting assembly and the loading and transfer drive assembly repeat the aforementioned lifting and transfer actions, thus enabling the material to be loaded layer by layer into the hopper assembly. In summary, the loading device provided by this invention can automatically remove the support plates and trays from the hopper assembly layer by layer, achieving automatic loading and empty tray recovery. Furthermore, the support plate can adapt to trays of various sizes, making it highly versatile. Attached Figure Description

[0049] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0050] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0051] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0052] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0053] This embodiment provides a feeding device for automatically feeding materials such as lenses or lens mounts to achieve lens module assembly. Figures 1-6 As shown, the feeding device includes a base plate 400, a lifting hopper mechanism 100, a feeding and transfer mechanism 200, and a feeding and pressing mechanism 300.

[0054] Among them, such as Figures 1-6As shown, the lifting hopper mechanism 100 includes a hopper lifting assembly and a hopper assembly. The hopper lifting assembly is mounted on the base plate 400, and the hopper assembly slides vertically on the base plate 400. The actuator of the hopper lifting assembly is connected to the hopper assembly to drive the hopper assembly to lift and lower. Multiple layers of support plates 110 are placed in the hopper assembly, and the support plates 110 are used to support the material tray 120. The loading and transferring mechanism 200 includes a loading and transferring drive assembly and a loading and transferring plate 201. The loading and transferring drive assembly is mounted on the base plate 400, and the actuator of the loading and transferring drive assembly is connected to the loading and transferring plate 201 to drive the loading and transferring plate 201 to translate horizontally in a first direction. The loading and transferring plate 201 can extend into the hopper assembly and support the support plates 110. The first direction is the X direction in the figure.

[0055] Specifically, the feeding device provided in this embodiment places multiple layers of support plates 110 in the hopper assembly. The support plates 110 are used to support the material tray 120. During feeding, the feeding transfer drive assembly drives the feeding transfer plate 201 to extend into the hopper assembly. The feeding transfer plate 201 extends below the support plate 110 corresponding to its height. The hopper lifting assembly drives the support plate 110 to move downward, so that it is supported by the feeding transfer plate 201. The support plate 110 is removed from the support of the hopper assembly. Then, the feeding transfer drive assembly drives the feeding transfer plate 201 to retract and detach from the hopper assembly, ready for material removal. After all the material in the tray 120 is removed, the loading and transfer drive assembly drives the loading and transfer plate 201 to place the empty tray 120 and the support plate 110 back into the hopper assembly. Subsequently, the loading and transfer drive assembly drives the loading and transfer plate 201 to retract outside the hopper assembly. The hopper lifting assembly drives the hopper assembly to lift and lower, so that the tray 120 and support plate 110 of the next or previous layer containing material move to the height of the corresponding loading and transfer plate 201. The hopper lifting assembly and the loading and transfer drive assembly repeat the aforementioned lifting and transfer actions, thereby realizing the layer-by-layer loading of material in the hopper assembly. In summary, the loading device provided by this utility model can automatically remove the support plate 110 and tray 120 from the hopper assembly layer by layer, realizing the functions of automatic loading and empty tray recovery. Moreover, the support plate 110 can be adapted to trays 120 of various sizes, making it highly versatile.

[0056] For example, such as Figure 2 and Figure 3 As shown, the hopper assembly includes a storage hopper 101 and multiple receiving rods 102 extending along a first direction. Both ends of the storage hopper 101 in the first direction are open structures to allow the material receiving plate 110 to enter and exit. The multiple receiving rods 102 are symmetrically arranged on the two inner side walls of the storage hopper 101, with two receiving rods 102 of the same height jointly supporting one material receiving plate 110. When the loading and transfer plate 201 supports the material receiving plate 110, the loading and transfer drive assembly drives the storage hopper 101 downwards, causing the material receiving plate 110 to disengage from the supporting rods 102.

[0057] For example, such as Figure 2 and Figure 3 As shown, both ends of the receiving rod 102 are provided with material plate limiting protrusions 1021, which are used to limit the position of the receiving plate 110 in the first direction.

[0058] Furthermore, such as Figure 4 As shown, a feeding limit strip 130 is installed around the four sides of the upper surface of the material support plate 110. The four feeding limit strips 130 together limit the material tray 120 on the material support plate 110. The installation position of the feeding limit strips 130 is adjustable. Furthermore, the material support plate 110 is provided with at least two strip-shaped mounting holes 111 or multiple circular mounting holes 112 corresponding to each feeding limit strip 130. The strip-shaped mounting holes 111 extend along a first direction or a horizontal second direction perpendicular to it (i.e., the Y direction in the figure). The multiple circular mounting holes 112 are distributed at intervals along the first direction or the second direction. The feeding limit strip 130 can be locked at any position of the strip-shaped mounting hole 111 or any two circular mounting holes 112 by bolt and nut structure, so as to adjust the distance of the feeding limit strip 130 from the center of the material support plate 110, thereby adapting to the size of the limiting range of material trays 120 of different sizes and improving versatility.

[0059] For example, such as Figure 2 As shown, the hopper lifting assembly includes a hopper lifting motor 103, a lifting synchronous belt structure (not shown in the figure), and a lifting ball screw structure 104. The hopper lifting motor 103 is a rotary motor and is installed below the base plate 400. The input end of the lifting synchronous belt structure is connected to the output shaft of the hopper lifting motor 103. The screw of the lifting ball screw structure 104 is arranged vertically and connected to the output end of the lifting synchronous belt structure. The screw nut of the lifting ball screw structure 104 is connected to the hopper assembly.

[0060] For example, such as Figure 2 As shown, the lifting hopper mechanism 100 also includes a lifting fixing plate 105, a hopper lifting slide rail 106, a hopper lifting slider 107, and a hopper lifting frame 108. The lifting fixing plate 105 is fixed vertically below the base plate 400. The hopper lifting slide rail 106 is fixed vertically to the lifting fixing plate 105. The hopper lifting slider 107 slides vertically on the hopper lifting slide rail 106. The hopper assembly is installed on the top of the hopper lifting frame 108. The hopper lifting frame 108 is fixedly connected to the hopper lifting slider 107 and the screw nut of the lifting ball screw structure 104. Furthermore, two hopper lifting slide rails 106 are arranged side by side, and two hopper lifting sliders 107 are slidably arranged on each hopper lifting slide rail 106. The four hopper lifting sliders 107 jointly support the hopper lifting frame 108, improving the stability of the lifting action of the hopper 101.

[0061] For example, such as Figure 5 and Figure 6 As shown, the loading and transfer drive assembly includes a loading and transfer seat 202, a transfer slide 203, a loading and transfer motor 204, and a transfer conveyor belt structure 205. The loading and transfer seat 202 is fixed to the base plate 400. The transfer slide 203 is slidably mounted on the loading and transfer seat 202 along a first direction. The loading and transfer plate 201 is fixed to the transfer slide 203. The loading and transfer motor 204 is a rotary motor mounted on the base plate 400. The actuator of the loading and transfer motor 204 is connected to the drive wheel of the transfer conveyor belt structure 205. The transfer slide 203 is connected to the conveyor belt of the transfer conveyor belt structure 205.

[0062] For example, such as Figure 5 and Figure 6 As shown, the feeding and transferring mechanism 200 also includes a feeding and transferring slide rail 206 and a feeding and transferring slider 207. The feeding and transferring slide rail 206 is fixed to the feeding and transferring seat 202 along a first direction, and the feeding and transferring slider 207 is slidably disposed on the feeding and transferring slide rail 206 along the first direction. The transfer slide 203 is fixedly connected to the feeding and transferring slider 207. Furthermore, two feeding and transferring slide rails 206 are arranged side by side, and two feeding and transferring sliders 207 are slidably disposed on each feeding and transferring slide rail 206. The four feeding and transferring sliders 207 jointly support the feeding and transferring seat 202, improving the stability of the feeding and transferring action.

[0063] For example, such as Figure 5 and Figure 6 As shown, the loading transfer plate 201 is connected to the transfer slide 203 at one end in the first direction, and the other end is suspended and can extend into the hopper assembly.

[0064] For example, such as Figure 5 As shown, the feeding and pressing mechanism 300 includes a feeding and pressing guide shaft 301, a feeding and pressing cylinder 302, and a feeding and pressing plate 303. The feeding and pressing guide shaft 301 is fixed vertically to the base plate 400. The feeding and pressing cylinder 302 is installed on the feeding and pressing guide shaft 301. The feeding and pressing plate 303 is slidably disposed vertically on the feeding and pressing guide shaft 301. The feeding and pressing plate 303 is located above the feeding transfer plate 201. The feeding and pressing cylinder 302 is used to drive the feeding and pressing plate 303 to move downward to press the material on the receiving plate 110, so as to avoid the material being unevenly placed in the material tray 120 and affecting the clamping and feeding, thereby improving reliability.

[0065] For example, such as Figure 5As shown, the feeding and pressing plate 303 extends along the second direction, covering the material receiving plate 110 in the second direction. That is, the feeding and pressing plate 303 can press a row of materials in the material tray 120 along the second direction at one time. Specifically, the feeding transfer plate 201 is provided with feeding and pressing guide shafts 301 and feeding and pressing cylinders 302 at both ends in the second direction. The two feeding and pressing cylinders 302 jointly drive the lifting and lowering action of the feeding and pressing plate 303.

[0066] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
