[0050] For the sake of illustration, a three-dimensional rectangular coordinate system is added in Figure 2 , wherein the direction of the X-axis is the first direction, i.e. the arrangement direction of the first clamping part 1212 relative to the second clamping part 1222, the direction of the Y-axis is the second direction, i.e. the arrangement direction of the plurality of side plates 1141, and the direction of the Z-axis is the third direction, i.e. the direction in which the first clamping lifting drive body 1212b drives the first clamping body 1212a to move.

[0051] Please refer to Figures 1-3 , the present embodiment provides a feeding device for grabbing one end of a material 13 and trimming the other end of the material 13, which comprises a transfer mechanism 11 and a stretching mechanism 12. The transfer mechanism 11 is provided with a feeding position 118. The stretching mechanism 12 comprises a material taking assembly 122, a stretching assembly 121 and a stretching driving assembly 123. The material taking assembly 122 is connected to the transfer mechanism 11 and is used to fix one end of the material 13. The stretching assembly 121 is connected to the stretching driving assembly 123 and is used to clamp the other end of the material 13. The stretching driving assembly 123 is connected to the material taking assembly 122 and is used to drive the stretching assembly 121 clamped to the other end of the material 13 to move in a first direction to straighten the material 13. The transfer mechanism 11 is used to drive the stretching mechanism 12 to move the straightened material 13 to the feeding position 118. Exemplarily, the material 13 can be an antenna of a notebook computer, wherein the antenna comprises an antenna body and a head, and the head is connected to one end of the antenna body.

[0052] In the feeding device, the stretching mechanism 12 is first moved to a position close to the material 13 by the moving mechanism 11, and the material 13 is aligned with the one end of the material 13 by the material taking assembly 122. Then, the one end of the material 13 is grabbed by the material taking assembly 122, and the other end of the material 13 is clamped by the stretching assembly 121. The stretching driving assembly 123 drives the stretching assembly 121 to move in the first direction to straighten the material 13. Finally, the moving mechanism 11 drives the stretching mechanism 12 to move, so that the material 13 straightened by the stretching mechanism 12 is moved to the feeding position 118. In this way, during the process of moving the stretching mechanism 12 with the material 13 grabbed to the feeding position 118 by the moving mechanism 11, the stretching mechanism 12 will automatically stretch the material 13, so as to simplify the work process, save time and effort, and improve the feeding efficiency.

[0053] Please refer to Figure 3 In some embodiments, the stretching assembly 121 comprises a movable piece 1211 and a first clamping piece 1212. The movable piece 1211 is connected to the stretching driving assembly 123. The first clamping piece 1212 is connected to the movable piece 1211 and used to clamp the other end of the material 13. The stretching driving assembly 123 is used to drive the movable piece 1211 to move the first clamping piece 1212 in the first direction.

[0054] In this way, the one end of the material 13 is first fixed by the material taking assembly 122, then the other end of the material 13 is clamped by the first clamping piece 1212, and finally the first clamping piece 1212 clamped to the other end of the material 13 is driven by the stretching driving assembly 123 to move in the direction away from the material taking assembly 122, so as to quickly straighten the material 13.

[0055] In some embodiments, the stretching driving assembly 123 comprises a driving roller 1231, a driven roller 1232, a transmission belt 1233 and a stretching driving piece 1234. The driving roller 1231 is rotationally connected to the material taking assembly 122. The driven roller 1232 is rotationally connected to the material taking assembly 122 and is spaced apart from the driving roller 1231 in the first direction. The axes of the driving roller 1231 and the driven roller 1232 extend in a second direction perpendicular to the first direction. The transmission belt 1233 is connected to the driving roller 1231 and the driven roller 1232. The first clamping piece 1212 is connected to the transmission belt 1233 and is slidingly connected to the material taking assembly 122. The stretching driving piece 1234 is connected to the driving roller 1231 and the material taking assembly 122. The stretching driving piece 1234 is used to drive the driving roller 1231 to rotate the transmission belt 1233 and the driven roller 1232.

[0056] Thus, the driving roller 1231 is driven to rotate by the stretching driving assembly 1234, so as to drive the transmission belt 1233 and the driven roller 1232 to rotate, when the transmission belt 1233 rotates around the driving roller 1231 and the driven roller 1232, the part of the transmission belt 1233 between the driving roller 1231 and the driven roller 1232 moves along the first direction, so as to drive the first clamping member 1212 to move along the first direction, and when the pulling force of the first clamping member 1212 to the material 13 is greater than the friction between the transmission belt 1233 and the driving roller 1231 and the driven roller 1232, the transmission belt 1233 and the driving roller 1231 and the driven roller 1232 will slip, so as to avoid that the first clamping member 1212 is pulled to break the material 13 by the excessive pulling force of the stretching driving assembly 1234, thereby reducing the yield of the stretching mechanism 12.

[0057] In some embodiments, the first clamping member 1212 comprises a first clamping body 1212a and a first clamping lifting driving body 1212b, the first clamping body 1212a is used to clamp the other end of the material 13, and the first clamping lifting driving body 1212b is connected to the first clamping body 1212a and is used to drive the first clamping body 1212a to move along a third direction which is perpendicular to the first direction. For example, the first clamping body 1212a can be a cylinder clamp, and the first clamping lifting driving body 1212b can be a lifting slide.

[0058] Thus, the first clamping body 1212a is driven to move along the third direction by the first clamping lifting driving body 1212b, so as to move along the third direction towards the other end of the material 13, so as to enable the first clamping body 1212a to quickly clamp the other end of the material 13, thereby improving the clamping efficiency of the material 13.

[0059] In some embodiments, the movable member 1211 comprises a sliding body 1211a and a pulling force detector 1211b, the sliding body 1211a is connected to the stretching driving assembly 123 and is slidingly connected to the material taking assembly 122, the material taking assembly 122 comprises a sliding groove, the sliding body 1211a is slidingly connected to the sliding groove, and the pulling force detector 1211b is connected to the sliding body 1211a and the first clamping lifting driving body 1212b and is used to detect the pulling force of the first clamping body 1212a when stretching the material 13. Specifically, the pulling force detector 1211b comprises a pulling force sensor and a corresponding type of controller which are electrically connected, wherein the pulling force sensor and the stretching driving assembly 1234 are electrically connected to the controller.

[0060] Thus, the sliding body 1211a is slidably connected to the material taking assembly 122, so that the movable element 1211 can stably move in the first direction, thereby improving the stability of the movable element 1211 during movement. The pulling force detector 1211b detects the pulling force of the first clamping body 1212a when pulling the material 13, and when the pulling force reaches a set threshold value, the material 13 is straightened. The pulling force detector 1211b closes the circuit of the stretching driving element 1234, so that the stretching mechanism 12 automatically stops the material 13, thereby avoiding damage to the material 13 due to excessive pulling force.

[0061] In some embodiments, the material taking assembly 122 includes a connecting frame 1221, a second clamping element 1222, and a suction accessory 1223. The connecting frame 1221 is connected to the material moving mechanism 11, the stretching assembly 121, and the stretching driving assembly 123. The second clamping element 1222 is arranged in the first direction and spaced apart from the first clamping element 1212, and is used to clamp one end of the material 13. The suction accessory 1223 is connected to the connecting frame 1221, and is arranged adjacent to the second clamping element 1222 and spaced apart from the first clamping element 1212 in the first direction. Thus, the suction accessory 1223 is used to first adsorb and fix the easily damaged part of one end of the material 13, thereby reducing the damage to the material 13 during stretching, and improving the yield of the material 13 during stretching.

[0062] In this embodiment, the suction accessory 1223 includes a suction body 1223a, a rotating driving body 1223b, and a suction lifting driving body 1223c. The suction body 1223a is connected to the rotating driving body 1223b, and the rotating driving body 1223b is used to drive the suction body 1223a to adjust the angle of the material 13. The rotating driving body 1223b is connected to the suction lifting driving body 1223c, and the suction lifting driving body 1223c is used to drive the rotating driving body 1223b to move the suction body 1223a in the third direction, so as to adsorb or release the material 13. The suction lifting driving body 1223c is connected to the connecting frame 1221. For example, the suction body 1223a can be a vacuum chuck, the rotating driving body 1223b can be a motor, and the suction lifting driving body 1223c can be a sliding table.

[0063] In this embodiment, the suction accessory 1223 further includes a visual positioning assembly 1223d, which is arranged adjacent to the rotating driving body 1223b, and is used to shoot and obtain the position of the material 13, so as to adsorb the material 13 by the suction body 1223a. The visual positioning assembly 1223d is a prior art component.

[0064] In the embodiment, the second clamping member 1222 comprises a second clamping body 1222a and a second clamping lifting driving body 1222b, the second clamping body 1222a is connected to the second clamping lifting driving body 1222b, the second clamping lifting body is connected to the connecting frame 1221, the second clamping body 1222a is used for clamping the part of the material 13 which is not easy to wear, and the second clamping lifting driving body 1222b is used for driving the second clamping body 1222a to move in the third direction.

[0065] In some embodiments, the transfer mechanism 11 comprises a bottom plate 111, a temporary storage assembly 112 and a transfer assembly 113, the temporary storage assembly 112 is arranged on the bottom plate 111 and is provided with a feeding position 118 for temporarily storing the straightened material 13, and the transfer assembly 113 is connected to the bottom plate 111 and is arranged in a spaced manner with the temporary storage assembly 112, and is used for driving the stretching mechanism 12 to move the straightened material 13 to the feeding position 118. Exemplarily, the transfer assembly 113 can be a mechanical hand.

[0066] In this way, the straightened material 13 by the stretching mechanism 12 is transferred to the feeding position 118 on the temporary storage assembly 112 by the transfer assembly 113, and the number of the feeding position 118 can be set to be multiple according to the production needs, so as to store multiple materials 13.

[0067] In some embodiments, the transfer mechanism 11 comprises a storage assembly 114, the storage assembly 114 comprises a plurality of side plates 1141, the plurality of side plates 1141 are arranged in a spaced manner along the second direction, and a storage bin 1142 is formed between any two adjacent side plates 1141, and each storage bin 1142 is used for accommodating the material 13. In this way, the plurality of side plates 1141 arranged in a spaced manner form a plurality of storage bins 1142, so as to store multiple groups of materials 13.

[0068] In some embodiments, the storage assembly 114 further comprises a first pressing member 115 and a second pressing member 116, the first pressing member 115 is connected to the transfer mechanism 11 and is used for pressing the other end of the material 13, and the second pressing member 116 is connected to the transfer mechanism 11 and is used for pressing one end of the material 13.

[0069] Thus, first, the second pressing member 116 pressing one end of the material 13 is moved away from the material 13, and one end of the material 13 is grabbed by the taking assembly 122 to move the one end of the material 13 upward by a distance, then the one end of the material 13 is pressed by the second pressing member 116 again, and the second pressing member 116 is moved away from the material 13, finally, the other end of the material 13 is grabbed by the stretching mechanism 12 and cooperates with the taking assembly 122 to stretch the material 13, so that the stretching mechanism 12 can grab and stretch a single material 13 in a single operation from the multi-layer stacked materials 13, thereby avoiding the disorder of the multi-layer materials 13 caused by the taking of the stretching mechanism 12.

[0070] In the embodiment, the first pressing member 115 includes a first pressing body 1151 and a first pressing driving body 1152, the first pressing body 1151 is connected to the first pressing driving body 1152, the first pressing driving body 1152 is connected to the bottom plate 111, and the first pressing driving body is used to drive the first pressing body 1151 to move along the third direction and press the other end of the material 13. Exemplarily, the first pressing driving body 1152 can be a pneumatic cylinder.

Exemplarily, the second pressing driving body 1162 and the third driving body can be slides.

[0072] In some embodiments, the storage assembly 114 further includes a limiting member 117 abutting the other end of the material 13 for positioning the material 13. Thus, the limiting member 117 cooperates with the side plate 1141 to abut the side end face of one end of the material 13 in the horizontal direction, so as to position the one end of the material 13, thereby enabling the stretching mechanism 12 to grab the material 13 more accurately, and improving the accuracy of the stretching mechanism 12 in grabbing the material 13.

[0073] In the embodiment, the limiting member 117 includes two first abutting blocks 1171 and a second abutting block 1172. The two first abutting blocks 1171 are arranged in the first direction and connected to the bottom plate 111, and are used for abutting the opposite two side ends of one end of the material 13 in the first direction. The second abutting block 1172 is used for abutting the side end face of the material 13 in the second direction.

[0074] The working principle of the feeding device is as follows:

[0075] Firstly, the transfer assembly 113 drives the stretching assembly 121 to move above the storage bin 1142. The visual positioning assembly 1223d takes a photo to obtain the position information of one end of the material 13, and moves the adsorption body 1223a above the easily-worn part of one end of the material 13 through the position information obtained by the visual positioning assembly 1223d.

[0076] Then, the adsorption lifting drive body 1223c drives the rotating drive body 1223b to move the adsorption body 1223a downward to abut the easily-worn part of one end of the material 13, so that the adsorption body 1223a adsorbs the easily-worn part of one end of the material 13.

[0077] Finally, the transfer assembly 113 drives the stretching assembly 121 to move from the storage bin 1142 to the temporary storage assembly 112. During the movement of the stretching assembly 121 from the storage bin 1142 to the temporary storage assembly 112, the second clamping member 1222 clamps the wear-resistant part of one end of the material 13, and the first clamping member 1212 clamps the other end of the material 13. The first clamping member 1212 is driven by the stretching drive assembly 123 to move in the first direction to straighten the material 13.
