[0047] Exemplary embodiments of the present application are described herein with reference to the accompanying drawings. It should be understood that the specific description is merely for the purpose of illustration and that the application is not limited to the specific embodiments described herein. Rather, the specific description is intended to illustrate the application by means of an example.

[0048] Figures 1 to 14 A blanking device according to an embodiment of the present application is shown, in particular a blanking device for blanking a nickel sheet (an example of a target object).

[0049] Referring to Figure 1 , the blanking device can include a feeding assembly 1, a blanking assembly 2, a measurement assembly 3, an unloading assembly 4, and a loading table 5, and the nickel sheet can sequentially flow through the feeding assembly 1, the blanking assembly 2, the measurement assembly 3, and the unloading assembly 4.

[0050] Referring to Figures 1 to 3 , the feeding assembly 1 can include a feeding grabbing component 11 and a feeding plastic disc conveying component 12. In the flow direction of the nickel sheet, the feeding grabbing component 11 can be located on the downstream side of the feeding plastic disc conveying component 12.

[0051] Referring to Figure 2 , the feeding grabbing component 11 can include a feeding X-axis module 111, a feeding Y-axis module 112, a rotating cylinder 113, a suction cylinder 114, and a feeding suction nozzle 115. Specifically, the feeding suction nozzle 115 is used to suck the nickel sheet. The feeding X-axis module 111 and the feeding Y-axis module 112 are used to drive the feeding suction nozzle 115 to move in the horizontal direction (X-axis direction, Y-axis direction), and the suction cylinder 114 is used to drive the feeding suction nozzle 115 to move in the vertical direction (a direction perpendicular to the X-axis direction and the Y-axis direction). The rotating cylinder 113 is used to drive the feeding suction nozzle 115 to rotate to adjust the angle of the nickel sheet.

[0052] Referring to Figure 3The plastic disc feeding conveying component 12 can include a conveying belt motor 121, a full box photoelectric sensor 122, an empty disc cylinder 123, a disc blocking cylinder 124, a disc blocking clamping cylinder 125, a lower disc cylinder 126, and a lower disc tray cylinder 127. Specifically, the plastic disc feeding conveying component 12 can define a first plastic disc feeding position 12a, a second plastic disc feeding position 12b, and a third plastic disc feeding position 12c, which can be arranged in the Y-axis direction. The first plastic disc feeding position 12a is used to store a plastic disc on which a nickel sheet is placed, and the third plastic disc feeding position 12c is used to store an empty plastic disc. The plastic discs can be arranged in a stack in the first plastic disc feeding position 12a and the third plastic disc feeding position 12c. The conveying belt motor 121 can drive the conveying belt to convey the plastic disc located in the first plastic disc feeding position 12a to the second plastic disc feeding position 12b and the third plastic disc feeding position 12c.

[0053] In the first plastic disc feeding position 12a, the lower disc cylinder 126 is used to clamp the second plastic disc (counted from the bottom up) in the horizontal direction. The lower disc tray cylinder 127 is used to drive the second plastic disc to move in the vertical direction, so that the first plastic disc (counted from the bottom up) and the second plastic disc are separated from each other. The first plastic disc separated from the second plastic disc can be conveyed by the conveying belt to the second plastic disc feeding position 12b.

[0054] In the second plastic disc feeding position 12b, the disc blocking cylinder 124 is used to drive the plastic disc to move in the vertical direction, so that the plastic disc can be in contact with or separated from the conveying belt. The disc blocking clamping cylinder 125 is used to clamp the plastic disc separated from the conveying belt in the horizontal direction, so that the plastic disc can be kept at a predetermined position without moving. After the plastic disc is kept at the predetermined position, the feeding suction nozzle 115 can suck the nickel sheet from the plastic disc.

[0055] In the third plastic disc feeding position 12c, the empty disc cylinder 123 is used to drive the plastic disc to move in the vertical direction, so that the first plastic disc can be moved upward and space is reserved for the plastic disc from the second plastic disc feeding position 12b. The full box photoelectric sensor 122 can be arranged at a specific height. Once the uppermost plastic disc reaches the specific height, the full box photoelectric sensor 122 can be triggered, so that the empty plastic disc can be timely recycled.

[0056] Referring to Figure 1 , Figures 4 to 10 , the blanking assembly 2 can include a blanking pre-positioning component 21, a blanking transfer component 22, and a punch component 23. In the flow direction of the nickel sheet, the blanking pre-positioning component 21 can be located on the upstream side of the blanking transfer component 22, and the punch component 23 can be located on the downstream side of the blanking transfer component 22.

[0057] Referring to Figures 4 to 8The punching positioning component 21 can include a first jig 211, a second jig 212, an XY adjusting platform 213, a positioning cylinder 214, and a positioning guide rail 215.

[0058] Referring to Figure 5 The first jig 211 can include a first positioning portion 21a and a first positioning hole 21b. The first positioning portion 21a can protrude in the vertical direction. A nickel sheet adapted to the first jig 211 can be placed on the first jig 211 and abut against the first positioning portion 21a. The first positioning hole 21b can pass through the first jig 211 in the vertical direction.

[0059] Referring to Figure 6 The second jig 212 can include a second positioning portion 21c and a second positioning hole 21d. The second positioning portion 21c can protrude in the vertical direction and form an edge adapted to the shape of the nickel sheet. The second positioning portion 21c can pass through the first jig 211 via the first positioning hole 21b and abut against the nickel sheet.

[0060] Here, the first positioning portion 21a can include a positioning strip in a long strip shape and a plurality of positioning protrusions arranged on both sides of the positioning strip and along the length direction (e.g., the Y-axis direction) of the positioning strip. One first positioning hole 21b can be provided on one side of the positioning strip in the length direction of the positioning strip. The size of the first positioning hole 21b can be greater than the cross-sectional size of the second positioning portion 21c, so that the second positioning portion 21c can move in the first positioning hole 21b. The first positioning portion 21a and the second positioning portion 21c can together position the nickel sheet in the horizontal direction.

[0061] Referring to Figure 7 and Figure 8 The positioning guide rail 215 can be installed on the second jig 212 for defining the movement direction of the second jig 212, or in other words, the direction in which the second jig 212 abuts against the nickel sheet. The end of the positioning cylinder 214 can be inserted into the second jig 212 via the second positioning hole 21d for abutting against the wall portion of the second positioning hole 21d to drive the second jig 212 to slide in the direction defined by the positioning guide rail 215. Under the drive of the positioning cylinder 214, the second jig 212 can move relative to the first jig 211, so that the first positioning portion 21a and the second positioning portion 21c can jointly clamp the nickel sheet, thereby achieving the positioning of the nickel sheet.

[0062] Here, the movement direction of the second jig 212 defined by the positioning guide rail 215 is inclined (here, the inclination means neither perpendicular nor parallel) relative to the extension direction of the positioning strip. After the second positioning portion 21c of the second jig 212 moves in the first positioning hole 21b, the second positioning portion 21c can position the nickel sheet in one direction with the positioning strip, and the second positioning portion 21c can position the nickel sheet in another direction, in particular, a direction perpendicular to the one direction, with the protrusions.

[0063] The first jig 211, the second jig 212, the positioning cylinder 214 and the positioning guide rail 215 can be placed on the XY adjustment platform 213, so that the isometric position of the blanking pre-positioning component 21 can be precisely adjusted. Under the adjustment of the XY adjustment platform 213, the positions of the first jig 211 and the second jig 212 can correspond to the feeding suction nozzle 115, so that the feeding grabbing component 11 can accurately transport the nickel sheet from the plastic tray to the first jig 211.

[0064] Further, the first jig 211 can place a plurality of nickel sheets, and the number of the second jig 212 and the number of the positioning cylinder 214 can correspond to the number of the nickel sheets. For example, in the present embodiment, the number of the nickel sheets can be two, and the two second jigs 212 can slide parallel and opposite to each other to abut against different nickel sheets, respectively.

[0065] The blanking pre-positioning component 21 can realize the rapid switching of nickel sheets of different shapes. When the shape of the nickel sheet changes, only the first jig 211 and the second jig 212 need to be replaced, without the need to re-arrange the positioning cylinder 214 and the positioning guide rail 215, so that the blanking pre-positioning component 21 can be suitable for nickel sheets of different shapes. The installation and debugging process of the blanking pre-positioning component 21 is simplified, effectively improving the ease of use of the blanking device.

[0066] Referring to Figure 9 , the blanking transfer component 22 can include a first blanking transfer X-axis module 221, a second blanking transfer X-axis module 222, a transfer guide rail 223, a blanking pre-transfer cylinder 224, a blanking pre-transfer suction nozzle 225, a blanking post-transfer cylinder 226 and a blanking post-transfer suction nozzle 227. Specifically, the blanking pre-transfer suction nozzle 225 is used to adsorb the nickel sheet at the first jig 211, and transport the nickel sheet to the punch component 23. The blanking pre-transfer cylinder 224 is used to drive the blanking pre-transfer suction nozzle 225 to move in the vertical direction, and the first blanking transfer X-axis module 221 is used to drive the blanking pre-transfer suction nozzle 225 to move in the horizontal direction along the transfer guide rail 223. The blanking post-transfer suction nozzle 227 is used to adsorb the nickel sheet at the punch component 23, and transport the nickel sheet to the rotary disc component 32. The blanking post-transfer cylinder 226 is used to drive the blanking post-transfer suction nozzle 227 to move in the vertical direction, and the second blanking transfer X-axis module 222 is used to drive the blanking post-transfer suction nozzle 227 to move in the horizontal direction along the transfer guide rail 223.

[0067] Further, the punch pre-transport suction nozzle 225 and the punch post-transport suction nozzle 227 can be adapted to the shape of the nickel sheet. The punch pre-transport suction nozzle 225 can be detachably mounted to the punch pre-transport suction cylinder 224, and the punch post-transport suction nozzle 227 can be detachably mounted to the punch post-transport suction cylinder 226. When the shape of the nickel sheet is changed, the punch transport component 22 can be used to transport nickel sheets of different shapes by replacing the punch pre-transport suction nozzle 225 and the punch post-transport suction nozzle 227.

[0068] Referring to Figure 10 , the punch component 23 can include a punch cylinder 231, an upper die 232, and a lower die 233. Specifically, the lower die 233 can be adapted to the shape of the nickel sheet, and the nickel sheet can be placed on the lower die 233. The punch cylinder 231 can drive the upper die 232 to move in the vertical direction, so that the upper die 232 can cooperate with the lower die 233 and punch the nickel sheet.

[0069] Referring to Figure 1 , Figures 11 to 13 , the measurement assembly 3 can include a probe component 31, a turntable component 32, and a visual measurement component 33.

[0070] Referring to Figure 11 , the probe component 31 can include an adjustable distance probe cylinder 311 and a probe 312. Specifically, the probe 312 can be in contact with the nickel sheet for measuring the electrical parameters of the nickel sheet (i.e., electrically measuring the nickel sheet), such as measuring the current and resistance. A plurality of probes 312 can be arranged parallel to each other and arranged according to the shape of the nickel sheet. The adjustable distance probe cylinder 311 is used to drive the probe 312 to move in the vertical direction.

[0071] Referring to Figure 12 , the turntable component 32 can include an index plate motor 321, an indexer 322, and a positioning turntable 323. Specifically, the positioning turntable 323 is used to place the punched nickel sheet. The probe component 31 and the visual measurement component 33 can be disposed radially outward of the positioning turntable 323 and spaced apart in the circumferential direction of the positioning turntable 323. The index plate motor 321 is used to drive the positioning turntable 323 to rotate via the indexer 322, thereby transporting the nickel sheet to a position corresponding to the probe component 31 and the visual measurement component 33.

[0072] Further, the positioning turntable 323 can be provided with a magnet, such as a permanent magnet or an electromagnet. The nickel sheet placed on the positioning turntable 323 can be attracted by the magnet, so that the nickel sheet and the positioning turntable 323 are fixed to each other, and the nickel sheet is not easy to deviate during rotation of the positioning turntable 323.

[0073] Referring to Figure 13The vision measurement component 33 can include a height-adjustable camera 331. Specifically, the height-adjustable camera 331 is used to take pictures of the punched nickel sheet, so as to accurately obtain the size parameters of the nickel sheet. By analyzing the size parameters of the nickel sheet, the nickel sheet that does not meet the size requirement can be identified. The height-adjustable camera 331 can be moved in the vertical direction to adapt to different sizes of the nickel sheet.

[0074] Referring to Figure 1 and Figure 14 The blanking component 4 can include a blanking grabbing component 41 and a blanking plastic tray conveying component 42. In the flow direction of the nickel sheet, the blanking grabbing component 41 can be located on the upstream side of the blanking plastic tray conveying component 42.

[0075] Referring to Figure 14 The blanking grabbing component 41 can include a robot 411, a blanking suction cup cylinder 412, and a blanking suction nozzle 413. Specifically, the blanking suction nozzle 413 is used to suck and position the qualified nickel sheet on the positioning turntable 323, and convey the nickel sheet to the plastic tray of the blanking plastic tray conveying component 42. The nickel sheet that does not pass the test (electrical test and vision measurement) will be blown off to the unqualified product collection box. The blanking suction cup cylinder 412 is used to drive the blanking suction nozzle 413 to move in the vertical direction. The robot 411 is used to drive the suction nozzle to move between the positioning turntable 323 and the blanking plastic tray conveying component 42.

[0076] Referring to Figure 1 The blanking plastic tray conveying component 42 can have the same or similar configuration as the feeding plastic tray conveying component 12. Specifically, the blanking plastic tray conveying component 42 can define a first blanking position 42a, a second blanking position 42b, and a third blanking position 42c. The first blanking position 42a is used to store empty plastic trays, and the third blanking position 42c is used to store plastic trays on which the punched nickel sheet is placed. The plastic trays can be arranged in a stack of the first blanking position 42a and the third blanking position 42c. The plastic trays located at the first blanking position 42a can be conveyed to the second blanking position 42b and the third blanking position 42c via the conveying belt. The blanking suction nozzle 413 of the blanking grabbing component 41 can place the punched nickel sheet on the plastic tray located at the second blanking position 42b.

[0077] Referring to Figure 1The loading table 5 is used to support the loading assembly 1, the punching assembly 2, the measuring assembly 3 and the unloading assembly 4. Specifically, the loading plastic disc conveying component 12, the punching pre-positioning component 21, the punch component 23, the rotating disc component 32 and the unloading plastic disc conveying component 42 can be arranged side by side in the X-axis direction. The loading suction nozzle 115 can be alternately located above the second loading position 12b and the first jig 211. The punching forward transfer suction nozzle 225 can be alternately located above the first jig 211 and the lower die 233.
