[0046] The embodiments of this case will be described in detail below with reference to the accompanying drawings.

[0047] Please see Figure 1 , Figure 1This is a schematic diagram of the structure of a material applicable to an embodiment of the present invention. Specifically, the material 200 includes a main body 210 and a plurality of protrusions 220.

In this embodiment, the first surface 210a has a planar structure, the two ends of the second surface 210b have grooves 210c, and there are three protrusions 220.

[0048] Please see Figure 2 This utility model provides a feeding device 100 for transferring and turning materials 200. The feeding device 100 includes a frame 110, a receiving mechanism 120, a pitch-changing mechanism 130, a transfer mechanism 140, and a lifting mechanism 150. The frame 110 can be an integral structure or a split structure. In this embodiment, the frame 110 is a split structure and is generally L-shaped.

[0049] Please see Figure 2 The frame 110 is used to support the feeding tray 300. The feeding tray 300 is provided with multiple feeding slots 300a for supporting materials 200. When the material 200 is located in the feeding slot 300a, the second surface 210b of the material 200 faces upward. The receiving mechanism 120 is located on the frame 110 and is used to support the receiving fixture 400. The receiving fixture 400 is provided with multiple loading slots 400a for loading materials 200. The distance between two adjacent loading slots 400a is different from the distance between two adjacent feeding slots 300a. When the material 200 is located in the loading slot 400a, the second surface 210b of the material 200 faces upward. The pitch-changing mechanism 130 is located on the frame 110 and is used to carry and adjust the spacing between multiple materials 200 so that the spacing between multiple materials 200 that are simultaneously taken out from multiple feeding troughs 300a is adapted to multiple loading troughs 400a, so that multiple materials 200 can be transferred from the feeding tray 300 to the receiving fixture 400. When the material 200 is located in the pitch-changing mechanism 130, the second surface 210b of the material 200 faces upward.

[0050] Please see Figure 2 The transfer mechanism 140 includes a robotic arm 141, a mounting base 142, a feeding and adsorption assembly 143, and a transfer assembly 144. The mounting base 142 is disposed on the robotic arm 141 to move and rotate under the drive of the robotic arm 141. The feeding and adsorption assembly 143 is disposed on the mounting base 142 and is used to adsorb the first surface 210a of multiple materials 200 located in the feeding tray 300 to drive the multiple materials 200 to the pitch-changing mechanism 130. The transfer assembly 144 is disposed on the mounting base 142. Specifically, the robotic arm 141 is adjacent to the frame 110.

[0051] Please see Figure 2The lifting mechanism 150 includes a lifting bracket 151, an adsorption assembly 152, and a lifting drive 153. The lifting bracket 151 is mounted on the frame 110. The adsorption assembly 152 is used to adsorb the first surface 210a of multiple materials 200 after the pitch change mechanism 130. The lifting drive 153 is mounted on the lifting bracket 151 and connected to the adsorption assembly 152, and is used to drive the adsorption assembly 152 to move the multiple materials 200 after the pitch change mechanism 130 away from the pitch change mechanism 130. The material transfer assembly 144 is used to clamp or internally support multiple protrusions 220 to move the multiple materials 200, so that the multiple materials 200 are detached from the adsorption assembly 152 and loaded into multiple loading slots 400a of the receiving fixture 400. The lifting drive 153 can be a lifting cylinder.

[0052] Please see Figure 3 The feeding and adsorption assembly 143 includes a feeding seat 1431 and a plurality of feeding and adsorption units 1432. The feeding seat 1431 is connected to the mounting seat 142. The plurality of feeding and adsorption units 1432 are all disposed on the side of the feeding seat 1431 away from the mounting seat 142. Each feeding and adsorption unit 1432 includes a plurality of feeding and adsorption elements 1432a. The plurality of feeding and adsorption elements 1432a are used to adsorb the first surface 210a of the material 200.

[0053] In this embodiment, each feeding and adsorption unit 1432 includes three feeding and adsorption components 1432a, which are arranged in a straight line and at equal intervals. Further, the feeding and adsorption assembly 143 includes four feeding and adsorption units 1432, which are arranged in a rectangular pattern. This means that the feeding and adsorption assembly 143 can adsorb two materials 200 from the feeding tray 300 at a time, and can simultaneously connect four materials 200 through adsorption.

[0054] Therefore, multiple feeding and adsorption units 1432 connect multiple materials 200 by adsorption, which can avoid damage to the materials 200 and ensure the quality of the supplied materials 200.

[0055] Please see Figure 3The material transfer assembly 144 includes a material transfer base 1441 and a material transfer unit 1442. The material transfer base 1441 is connected to the mounting base 142 and is spaced apart from the loading base 1431 along the rotation direction of the mounting base 142. The material transfer unit 1442 includes a material transfer drive 1442a and two clamping members 1442b. Each clamping member 1442b includes a slider 1442c and two clamping bodies 1442d respectively connected to the slider 1442c. The two clamping bodies 1442d on one slider 1442c correspond one-to-one with the two clamping bodies 1442d on the other slider 1442c. The material transfer drive 1442a is located on the material transfer base 1441 and connected to the two sliders 1442c, and is used to drive the two sliders 1442c to move so that the corresponding two clamping bodies 1442d fix a material 200 by clamping or supporting the inner protrusion 220.

[0056] In this embodiment, the material transfer drive 1442a is a bidirectional cylinder. There are two material transfer units 1442, which are arranged at intervals. That is, the material transfer assembly 144 can fix two materials 200 from the protruding adsorption assembly 152 at a time, and can connect four materials 200 at the same time.

[0057] Therefore, fixing multiple materials 200 by means of internal support or clamping can simplify the structure of the material transfer component 144, thereby helping to reduce the manufacturing cost of the material transfer component 144.

[0058] Please see Figure 2 and Figure 4 The pitch-changing mechanism 130 includes a pitch-changing bracket 131, a positioning element 132, a pitch-changing drive element 133, and a movable element 134. The pitch-changing bracket 131 is mounted on the frame 110. The positioning element 132 is mounted on the pitch-changing bracket 131 and has a first positioning groove 132a. The first positioning groove 132a is used to position the material 200 and ensure that the first surface 210a of the material 200 faces upwards. The pitch-changing drive element 133 is mounted on the pitch-changing bracket 131. The movable element 134 is connected to the pitch-changing drive element 133 and has a second positioning groove 134a. The second positioning groove 134a is used to position the material 200 and ensure that the first surface 210a of the material 200 faces upwards. The pitch-changing drive element 133 drives the movable element 134 to move closer to or further away from the positioning element 132 to adjust the distance between the first positioning groove 132a and the second positioning groove 134a. Specifically, the shapes of the first positioning groove 132a and the second positioning groove 134a are adapted to the material 200.

[0059] Therefore, by moving the movable part 134 closer to or further away from the positioning part 132 to adjust the distance between the first positioning groove 132a and the second positioning groove 134a, the manufacturing difficulty of the variable pitch mechanism 130 is reduced, which helps to reduce the manufacturing cost of the variable pitch mechanism 130.

[0060] Please see Figure 4The positioning component 132 includes a positioning plate 1321 and a plurality of positioning blocks 1322. The positioning plate 1321 is disposed on the pitch bracket 131. The plurality of positioning blocks 1322 are all connected to the positioning plate 1321 and surround the positioning plate 1321 to form a first positioning groove 132a. The movable component 134 includes a movable plate 1341 and a plurality of movable blocks 1342. The movable plate 1341 is connected to the pitch drive component 133. The plurality of movable blocks 1342 are all connected to the movable plate 1341 and surround the movable plate 1341 to form a second positioning groove 134a.

[0061] In this embodiment, multiple movable blocks 1342 are located on the same side of the movable plate 1341, and multiple positioning blocks 1322 are located on the same side of the positioning plate 1321 and are detachably connected to the positioning plate 1321 respectively. For example, the positioning blocks 1322 are connected to the positioning plate 1321 by plugging or snapping, which can adjust the shape of the first positioning groove 132a and the second positioning groove 134a based on the specific structure of the material 200, thereby increasing the range of the positioning member 132 and the movable member 134 that can adapt to the material 200.

[0062] Please see Figure 4 The distance between the two positioning blocks 1322 located in the moving direction of the moving plate 1341 gradually increases in the direction away from the positioning plate 1321.

[0063] Therefore, through the above arrangement, the positioning block 1322 and the movable block 1342 can guide the material 200, which is beneficial to improving the efficiency of positioning the material 200 into the first positioning groove 132a and the second positioning groove 134a.

[0064] Please see Figure 4 There are two first positioning slots 132a, which are spaced apart along the movement direction of the movable member 134. There are two movable members 134, which are located on both sides of the positioning member 132 and are respectively connected to the variable pitch drive member 133. The variable pitch drive member 133 is used to synchronously drive the two movable members 134 to move closer to or away from the positioning member 132.

[0065] In this embodiment, the pitch-changing drive 133 is a bidirectional cylinder. Each movable part 134 and the adjacent positioning part 132 form a pitch-changing unit. That is, each pitch-changing unit can realize the pitch change between two materials 200 at a time, and the pitch-changing mechanism 130 can realize the pitch change between four materials 200 at the same time.

[0066] Please see Figure 5The adsorption assembly 152 includes a fixed base 1521 and multiple adsorption units 1522. The fixed base 1521 is connected to a lifting drive 153. The multiple adsorption units 1522 are all disposed on the fixed base 1521. Each adsorption unit 1522 includes multiple adsorption elements 1522a. The multiple adsorption elements 1522a are used to adsorb the first surface 210a of the material 200.

[0067] In this embodiment, each adsorption unit 1522 includes three adsorption elements 1522a, which are arranged in a straight line and at equal intervals. Further, the adsorption assembly 152 includes four adsorption units 1522, which are arranged in a rectangular pattern. This means that the adsorption assembly 152 can adsorb two different amounts of material 200 from the variable-gap mechanism 130 at a time, and can simultaneously connect four materials 200 through adsorption.

[0068] Therefore, the multiple adsorption units 1522 connect multiple materials 200 by adsorption, which can avoid damage to the materials 200 and ensure the quality of the supplied materials 200.

[0069] Please see Figure 3 The transfer mechanism 140 also includes a tray drive 145 and two tray clamping members 146. The tray drive 145 is disposed on the mounting base 142 and is arranged sequentially with the loading base 1431 and the transfer base 1441 along the rotation direction of the mounting base 142. The two tray clamping members 146 are connected to the tray drive 145 so that they move closer to each other under the drive of the tray drive 145 to clamp the loading tray 300. In this embodiment, the tray drive 145 is a bidirectional cylinder.

[0070] Therefore, by setting up the above, the transfer function of the feeding tray 300 is concentrated on the mounting base 142, which simplifies the structure of the feeding device 100 and reduces the production cost of the feeding device 100.

[0071] In some embodiments, the transfer mechanism 140 further includes a fixture drive 147 and two fixture clamping members 148. The fixture drive 147 is disposed on the mounting base 142 and is arranged sequentially with the loading base 1431 and the transfer base 1441 along the rotation direction of the mounting base 142. The two fixture clamping members 148 are connected to the fixture drive 147 so that they move closer to each other under the drive of the fixture drive 147 to clamp the receiving fixture 400. In this embodiment, the fixture drive 147 is a bidirectional cylinder.

[0072] Therefore, by setting up as described above, the transfer function of the receiving fixture 400 is concentrated on the mounting base 142, which simplifies the structure of the feeding device 100 and reduces the production cost of the feeding device 100.

[0073] Taking the simultaneous transfer of two materials 200 in a single operation as an example, the working process of the above-mentioned feeding device 100 is roughly as follows:

[0074] First, the robotic arm 141 drives the mounting base 142 to move the feeding and adsorption assembly 143 to the feeding tray 300 so that the feeding and adsorption assembly 143 adsorbs the first surface 210a of the two materials 200 located in the feeding tray 300.

[0075] Next, the robotic arm 141 drives the mounting base 142 to move the feeding and adsorption assembly 143 to the pitch mechanism 130. The feeding and adsorption assembly 143 places the two materials 200 into the first positioning groove 132a and the second positioning groove 134a respectively. At this time, the first surface 210a of the material 200 faces upward. The pitch drive 133 drives the movable part 134 to move closer to or away from the positioning part 132 to adjust the distance between the first positioning groove 132a and the second positioning groove 134a.

[0076] Subsequently, the lifting drive 153 drives the adsorption assembly 152 to move the two materials 200 with the adjusted spacing to disengage from the pitch mechanism 130. During this process, the second surface 210b of the material 200 faces downward.

[0077] Finally, the robotic arm 141 drives the mounting base 142 to move the material transfer assembly 144, so that the material transfer assembly 144 clamps or supports the inner protrusion 220 to drive the two materials 200 to detach from the adsorption assembly 152, and loads the two materials 200 into the loading slot 400a of the receiving fixture 400. At this time, the second surface 210b of the material 200 faces upward, thereby realizing the flipping and transfer of the two materials 200.

[0078] Therefore, the aforementioned feeding device 100 can continuously complete the transfer, pitch change, flipping, and collection of multiple materials 200, reducing labor intensity and improving feeding efficiency. Furthermore, the aforementioned feeding device 100 has a simple structure and low production cost.
