For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be internal communication between two elements or an interaction relationship between two elements. In the description of the present invention, it should be noted that the meaning of "plurality" is two or more, unless otherwise clearly specified and limited. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0044] The following describes in detail various embodiments of the present invention in conjunction with the accompanying drawings.

[0045] See Figure 1 The present invention provides a feeding device 100 comprising a loading mechanism 110, a collection mechanism 120, and a transfer mechanism 130. The loading mechanism 110 is used to feed a plurality of stacked trays, each of which is loaded with material. The transfer mechanism 130 is used to sequentially remove the loaded trays from the loading mechanism 110. After the material on the trays is removed by an external unloading mechanism, the transfer mechanism 130 drives the empty trays to be sequentially placed on the collection mechanism 120, thereby achieving stacked collection of the plurality of empty trays. The material may be a lens.

[0046] For ease of description, a three-dimensional coordinate system is added to some of the drawings. Specifically, the X-axis direction is a first direction, the Y-axis direction is a second direction, and the Z-axis direction is a third direction. The X-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other.

[0047] See Figure 1 The loading mechanism 110 includes a loading bracket 111 and a loading seat 112. The loading seat 112 is slidably mounted on the loading bracket 111 along the X-axis and is used to support multiple stacked material trays. The material trays are used to load materials. The collection mechanism 120 includes a collection bracket 121 and a loading seat 122. The collection bracket 121 is spaced apart from the loading bracket 111 along the Y-axis. The collection seat 122 is slidably mounted on the collection bracket 121 along the X-axis and is used to stack and collect multiple material trays. The transfer mechanism 130 includes a transfer bracket 131, a horizontal drive 132, a support 133, a clamping assembly 134, and a lifting drive 135. The transfer bracket 131 is spaced apart from the loading bracket 111 along the X-axis. The horizontal drive 132 is mounted on the transfer bracket 131 and connected to the support 133, driving the support 133 to move along the Y-axis. The clamping assembly 134 is used to clamp the material tray. The lifting drive 135 is mounted on the support 133 and connected to the clamping assembly 134, driving the clamping assembly 134 to move along the Z-axis. The clamping assembly 134, under the action of the lifting drive 135 and the horizontal drive 132, is used to clamp the material trays located on the loading bracket 112 one by one along the Z-axis, move them to the collection base 122, and stack them.

[0048] Exemplarily, both the horizontal driving member 132 and the lifting driving member 135 may be stepping motors.

[0049] See Figure 1 and Figure 2The loading bracket 111 and the collecting bracket 121 each include a base plate 1111, two support members 1112, and a stopper 1113. The two support members 1112 are both provided on the base plate 1111 and spaced apart along the Y-axis direction. A slide rail 1114 extending along the X-axis direction is provided on the side of each support member 1112 facing away from the base plate 1111. The loading seat 112 and the collecting seat 122 are respectively slidably connected to the corresponding slide rails 1114. The stopper 1113 is respectively connected to the two support members 1112 and is located between the two support members 1112 and the transfer bracket 131. The stopper 1113 is used to stop the loading seat 112 or the collecting seat 122.

[0050] Thus, a space for the external drive assembly to operate is formed between the two supports 1112. This external drive assembly drives the loading base 112 and the collecting base 122 along the X-axis. The external drive can be a stepper motor or a robotic arm. Furthermore, a stopper 1113 limits the loading base 112 and the collecting base 122, marking their positions and facilitating the operation of the transfer mechanism 130.

[0051] See Figure 1 and Figure 2 The loading base 112 and the collecting base 122 each include a base plate 1121, a positioning member 1122, a handle 1123, and a plurality of position limiting members 1124. The base plate 1121 is slidably connected to the corresponding slide rail 1114 along the X-axis direction. The base plate 1121 is used to carry a plurality of stacked material trays. The positioning member 1122 is connected to the side of the base plate 1121 facing the stopper 1113 and is used to abut the stopper 1113 to position the base plate 1121. The handle 1123 is connected to the side of the base plate 1121 facing away from the positioning member 1122 and is used to drive the base plate 1121 to move. The plurality of position limiting members 1124 are all connected to the base plate 1121 and are spaced apart along the periphery of the base plate 1121 to limit the position of the plurality of stacked material trays.

[0052] In this embodiment, the substrate 1121 is roughly rectangular, and the multiple limiting members 1124 include four limiting rods 1124a and two limiting blocks 1124b. The two limiting blocks 1124b are arranged at intervals along the Y-axis direction, and the structure of each limiting block 1124b facing the other limiting block 1124b is adapted to the edge structure of the material tray to form a clamp for the material tray at the lowest end of the multiple stacked material trays. The four limiting rods 1124a are respectively arranged at the four end corners of the substrate 1121, and are used to form a stop for the multiple stacked material trays in the Z-axis direction to prevent the material trays from scattering.

[0053] See Figure 1In order to prevent the stacked multiple material trays from exceeding the stop range of the multiple position limiting members 1124, in this embodiment, the feeding device 100 further includes multiple height limiting members 140. The multiple height limiting members 140 are sequentially arranged along the Y-axis direction and are arranged close to the transfer bracket 131. Each height limiting member 140 includes a height limiting support rod 141 and an infrared sensor 142. The height limiting support rod 141 is higher than the loading seat 112 and the collecting seat 122 in the Z-axis direction. The infrared sensor 142 is arranged at the top of the height limiting support rod 141 and is used to detect the stacked multiple material trays based on a set standard and transmit an alarm message to an external processor when the height of the stacked multiple material trays exceeds the preset standard.

[0054] See Figure 1 and Figure 2 One of the sides of the positioning member 1122 facing the stop member 1113 and the side of the stop member 1113 facing the positioning member 1122 is provided with a positioning pin 1122a, and the other side is provided with a positioning hole 1113a adapted for the positioning pin 1122a. The positioning pin 1122a and the positioning hole 1113a are inserted and matched to position the positioning member 1122 and the stop member 1113.

[0055] Therefore, the insertion and matching of the positioning pin 1122a and the positioning hole 1113a can improve the positioning accuracy of the loading bracket 111 and the loading seat 112, as well as the collecting bracket 121 and the collecting seat 122.

[0056] In this embodiment, the positioning pin 1122a is disposed on the side of the positioning member 1122 facing the stop member 1113, and the positioning hole 1113a is disposed on the side of the stop member 1113 facing the positioning member 1122, wherein the positioning hole 1113a passes through the stop member 1113 along the X-axis direction. In other embodiments, the positioning pin 1122a may be disposed on the side of the stop member 1113 facing the positioning member 1122, and the positioning hole 1113a may be disposed on the side of the positioning member 1122 facing the stop member 1113.

[0057] To improve positioning accuracy, multiple positioning pins 1122a and positioning holes 1113a can be provided, and the multiple positioning pins 1122a and the multiple positioning holes 1113a can correspond one to one. In this embodiment, there are two positioning pins 1122a and two positioning holes 1113a. In other embodiments, there can be three or more positioning pins 1122a and two positioning holes 1113a.

[0058] See Figure 2 The feeding bracket 111 and the collecting bracket 121 also include a magnetic member 1115. The magnetic member 1115 is arranged on the stopper 1113 or the positioning member 1122, wherein when the magnetic member 1115 is arranged on the stopper 1113, the positioning member 1122 is set to be a metal component, and when the magnetic member 1115 is arranged on the positioning member 1122, the stopper 1113 is set to be a metal component.

[0059] Therefore, through the above-mentioned arrangement, the relative stability of the stopper 1113 and the positioning member 1122 can be improved, thereby preventing the loading seat 112 and the collecting seat 122 from shaking during operation.

[0060] In this embodiment, two magnetic members 1115 are provided on the stopper 1113, and the two magnetic members 1115 are spaced apart along the Y-axis direction, and the positioning member 1122 is a metal component. In other embodiments, the magnetic members 1115 can also be provided on the positioning member 1122, and the stopper 1113 can be provided as a metal component.

[0061] See Figure 2 In this embodiment, the feeding bracket 111 and the collecting bracket 121 also include a displacement sensor 1116. The displacement sensor 1116 is provided on the stopper 1113, and is used to detect the positioning member 1122 and transmit information to an external processor after the positioning member 1122 reaches a preset position.

[0062] Therefore, the positioning accuracy of the positioning member 1122 and the stop member 1113 can be improved by using the displacement sensor 1116 .

[0063] See Figure 1 and Figure 3 The clamping assembly 134 includes a clamping driver 1341 and two clamping members 1342. The two clamping members 1342 are spaced apart along the Y-axis. The clamping driver 1341 is provided on the lifting driver 135 and connects the two clamping members 1342, driving the two clamping members 1342 toward or away from each other. In this embodiment, the clamping driver 1341 is a bidirectional telescopic cylinder.

[0064] Therefore, through the above configuration, the working space of the clamping assembly 134 can be reduced, which is conducive to the miniaturization of the clamping assembly 134.

[0065] See Figure 1 and Figure 3 Each clamping member 1342 includes a connecting body 1342a and a clamping body 1342b. The connecting body 1342a is connected to the clamping driving member 1341, and the clamping body 1342b is detachably connected to the connecting body 1342a and extends along the X-axis direction.

[0066] In this embodiment, the two clamping bodies 1342b are parallel to each other, which is beneficial to reducing the space occupied by the clamping assembly 134. In addition, the clamping body 1342b is detachably connected to the connecting body 1342a, which facilitates the disassembly and assembly of the clamping body 1342b.

[0067] See Figure 3Each clamping member 1342 further includes a plurality of flexible protrusions 1342c. The plurality of flexible protrusions 1342c are connected to one side of the corresponding clamping member 1342b facing the other clamping member 1342b, and the plurality of flexible protrusions 1342c are spaced apart along the X-axis direction.

[0068] Therefore, the multiple flexible protrusions 1342c can achieve the clamping of the material tray by the clamping member 1342 in a multi-point contact manner, which can not only increase the clamping force of the clamping member 1342 on the material tray, but also reduce the damage to the material tray caused by hard contact.

[0069] It should be noted that the shapes and positions of the multiple flexible protrusions 1342c can be adaptively set based on the side structure of the tray.

[0070] See Figure 3 and Figure 4 The connecting body 1342a includes a slider 1342d and a mounting block 1342e. The slider 1342d includes a sliding portion 1342f and a protruding portion 1342g. The sliding portion 1342f is connected to the clamping drive member 1341. The protruding portion 1342g is connected to the corresponding sliding portion 1342f toward one side of the other sliding portion 1342f and extends along the Y-axis direction. The two protruding portions 1342g are spaced apart along the Z-axis direction. The mounting block 1342e is connected to the sliding portion 1342f and is detachably connected to the clamping body 1342b.

[0071] Therefore, the two protruding portions 1342g can limit the two sliding portions 1342f in the Y-axis direction, thereby limiting the travel of the two connecting bodies 1342a in the Y-axis direction.

[0072] In this embodiment, the sliding portion 1342f and the protruding portion 1342g are an integrated structure, which helps to reduce the difficulty of processing the slider 1342d.

[0073] See Figure 3 Each holding member 1342 further includes a cover plate 1342h. The cover plate 1342h is connected to the corresponding holding body 1342b and extends from the corresponding holding body 1342b to the other holding body 1342b. The cover plate 1342h is used to abut the top of the material tray.

[0074] Therefore, the cover plate 1342h can improve the accuracy of the clamping assembly 134 in clamping the material tray.

[0075] In order to improve the degree of automation of the clamping assembly 134, in this embodiment, the clamping assembly 134 also includes a material sensor 1343, which is connected to the connector 1342a and electrically connected to the clamping drive 1341. When the material sensor 1343 does not detect the material, the clamping drive 1341 drives the two connectors 1342a away from each other. When the material sensor 1343 detects the material, the clamping drive 1341 drives the two connectors 1342a closer to each other to clamp the material.

[0076] The working process of the feeding device 100 is roughly as follows:

[0077] First, multiple trays loaded with materials are stacked and placed on the loading base 112. The loading base 112 is manually or externally driven by a robot to move the multiple trays loaded with materials to the bottom of the clamping assembly 134.

[0078] Then, the clamping assembly 134, under the joint action of the lifting drive 135 and the horizontal drive 132, clamps the topmost material tray on the loading seat 112 and moves to above the collecting seat 122;

[0079] Subsequently, the material is removed from the tray by an external unloading mechanism, wherein the external unloading mechanism can be a robot;

[0080] Finally, the lifting drive 135 drives the supporting seat 133 to move the clamping assembly 134 and the empty tray downward, so that the empty tray is placed on the collecting seat 122 .

[0081] By repeating the above steps, a plurality of trays loaded with materials on the loading seat 112 can be sequentially transferred, and a plurality of empty trays can be stacked and collected on the collecting seat 122 .

[0082] Therefore, the feeding device 100 can realize the loading and collection of multiple stacked material trays through a single transfer mechanism 130 , which has a compact structure, reduces the working space of the feeding device 100 , and is conducive to the miniaturization of the feeding device 100 .

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be encompassed within the present invention.
