[0030] Working principle: When working, place the alloy resistor 108 to be encapsulated in the discharge tray 102, unfold and place the receiving tape 207 at the lower end of the transportation component 2, start the vibration motor 103 to work. The vibration motor 103 drives the discharge tray 102 to vibrate on the first base 101. The alloy resistors 108 move and arrange on the discharge tray 102 and enter the placement rack 206. During the movement of the alloy resistors 108, drive the two sets of push plates 109 to approach each other, and the two sets of alloy resistors 108 adjust the orientation of the alloy resistors 108 to prevent the alloy resistors 108 from being blocked during transportation. At the same time, start the air outlet 110 to blow air on the alloy resistors 108, and the air outlet 110 cleans the surface of the alloy resistors 108. When a blockage occurs on the discharge tray 102, drive the dredging block 112 to slide on the first adjustment frame 111. The dredging block 112 fits with the blocked alloy resistor 108 on the discharge tray 102, and start the first adjustment frame 111 to slide on the discharge tray 102. The first adjustment frame 111 drives the dredging block 112 to push out the blocked alloy resistor 108, completing the dredging of the blocked position on the discharge tray 102. When the alloy resistor 108 passes through the lower end of the pickup rack 105, the detection camera on the pickup rack 105 detects the defects on the surface of the alloy resistor 108. If an unqualified alloy resistor 108 is found, drive the baffle 113 to slide on the discharge tray 102. The baffle 113 blocks the alloy resistor 108 on the discharge tray 102, stopping the transportation of the alloy resistor 108 to prevent the defective alloy resistor 108 from entering the transportation component 2. At the same time, drive the first adjustment block 106 to slide on the pickup rack 105. The first adjustment block 106 drives the suction head 107 to align with the defective alloy resistor 108, drive the pickup rack 105 to slide on the first base 101. The pickup rack 105 drives the suction head 107 to fit with the alloy resistor 108, start the suction head 107, and the suction head 107 adsorbs the alloy resistor 108. Drive the pickup rack 105 and the first adjustment block 106 to place the defective alloy resistor 108 in the recovery tank 114, drive the baffle 113 to reset, and continue to transport the alloy resistor 108. After the alloy resistor 108 enters the transportation component 2, it arranges on the placement rack 206. When three sets of alloy resistors 108 are arranged on the placement rack 206, drive the baffle 113 to block the discharge tray 102 to prevent the alloy resistor 108 from piling up on the placement rack 206.

[0031] When transporting the alloy resistor 108 on the placement rack 206, first adjust the initial positions of multiple groups of second suction heads 212. The alloy resistors 108 of different specifications have different lengths and different positions within the placement rack 206. Adjust the initial positions of the second suction heads 212 according to different alloy resistors 108. Drive the adjusting head 218 to slide on the second adjusting block 216. The adjusting head 218 is inserted onto the first connecting column 219. At this time, the connection between the adjusting head 218 and the second mounting rack 208 is completed. Drive the second adjusting block 216 to slide on the first mounting rack 204. The second adjusting block 216 drives the adjusting head 218 and the second mounting rack 208 to move. When the second mounting rack 208 reaches the initial position, start the electromagnet block on the second adjusting rack 203 to fix the second mounting rack 208. When adjusting the initial position of the second mounting rack 208, synchronously adjust the initial position of the pressing block 221. Drive the third adjusting block 220 to slide on the adjusting plate 213. The third adjusting block 220 drives the pressing block 221 to move. The pressing block 221 is always aligned with the limiting block 215. When transferring the alloy resistor 108, drive the second adjusting rack 203 to slide on the transport rack 202.

The second adjusting rack 203 drives the second suction heads and the alloy resistor 108 to rise. Subsequently, drive the transport rack 202 to slide on the second base 201. The transport rack 202 drives multiple groups of alloy resistors 108 to move above the receiving tape 207. Drive the adjusting plate 213 to slide on the first mounting rack 204. The adjusting plate 213 drives the pressing block 221 to descend and approach the limiting block 215. At the same time, drive the third adjusting rack 214 to slide on the first mounting rack 204. The third adjusting rack 214 presses the limiting column 211. The limiting column 211 slides within the second mounting rack 208. The limiting column 211 releases the limit on the suction rack 209. When the pressing block 221 presses the limiting block 215, the limiting block 215 drives the suction rack 209 to slide on the second mounting rack 208, and simultaneously compresses the second spring 210. The lengths of the limiting columns 211 are different, and the pressing degrees on the limiting block 215 are also different. At this time, the distances that the limiting block 215 drives the suction rack 209 to move are also different, so that when multiple groups of limiting blocks 215 are pressed, they drive the suction rack 209 to move to a position aligned with the grooves on the receiving tape 207. At this time, the alloy resistors 108 adsorbed by the second suction heads 212 are also aligned with the groove positions on the receiving tape 207. Drive the second adjusting rack 203 to move. The second adjusting rack 203 drives multiple groups of second suction heads 212 to descend. The second suction heads 212 place the alloy resistors 108 into the grooves of the receiving tape 207, completing the placement of the alloy resistors 108. When driving the adjusting plate 213 to reset, the limiting block 215 resets through the deformation restoring force of the second spring 210, and the suction rack 209 returns to the initial position. Drive the third adjusting rack 214 to reset.The limit post 211 is inserted into the adsorption frame 209 through the deformation restoring force of the fourth spring, and the limit post 211 fixes the adsorption frame 209.

[0032] When the size of the alloy resistor 108 changes or the position of the groove on the material receiving tape 207 changes, it is necessary to adjust the distance between multiple groups of the second adsorption heads 212 during placement. At this time, different pressing blocks 221 need to be replaced. When removing the pressing block 221, drive the transfer rack 306 to rotate on the fourth adjusting frame 305. The transfer rack 306 drives the adsorption column 307 towards a group of pressing blocks 221 to be removed. Drive the mounting rack 302 to slide on the third base 205. The mounting rack 302 drives the adsorption column 307 to align with the second connecting column 222 on the pressing block 221. Drive the adsorption column 307 to slide on the transfer rack 306. The adsorption column 307 is inserted into the second connecting column 222 and start the electromagnet block on the adsorption column 307 to complete the fixation of the pressing block 221. Turn off the electromagnet block on the adjusting block 220. Start the fourth adjusting frame 305 to slide on the placement barrel 301. At this time, remove the pressing block 221 on the adjusting block 220. Drive the fourth adjusting frame 305, the transfer rack 306 and the adsorption column 307, and place the removed pressing block 221 on the placement groove 304 of the placement tray 303. When installing the pressing block 221, when driving the adsorption column 307 to move on the transfer rack 306, the second connecting column 222 is inserted into the adsorption column 307, and start the electromagnet block on the adsorption column 307 to fix the second connecting column 222.
