Detailed implementation manners

[0040] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention, and should not be construed as a limitation to the present invention.

[0041] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as up, down, front, back, left, right, etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0042] In the description of the present invention, "a plurality of" means more than two. If the first and the second are described, they are only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0043] In the description of the present invention, unless otherwise clearly defined, terms such as "arrangement", "installation", and "connection" should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0044] It should be understood that a wire head column and a terminal slot are provided on one end face of the skeleton. The wire head column is used for winding the wire head of the wire, and the terminal slot is used for positioning and fixing the terminal, and the terminal is also called a pin. The skeleton has at least two specifications or signals, and the height of the skeleton of each specification or signal is different. The terminal tape is a strip material formed by connecting a plurality of terminals in sequence through auxiliary materials, and the terminals can be separated by cutting or punching the auxiliary materials.

[0045] Refer to Figures 1 to 3 , the present invention discloses an inductor production line, including a machine table 100, a skeleton feeding device 200, a winding device 300, and a tape inspection mechanism 400, an unqualified semi-finished product blanking mechanism, a terminal punching device 500, an electrical detection mechanism 600, a flying wire cutting mechanism 700, a defective product blanking mechanism 800, and a qualified product blanking device 900 arranged around the loop conveyor mechanism 120.

[0046] Refer to Figure 1 , a linear conveyor mechanism 110, a loop conveyor mechanism 120, and a transfer handling mechanism 130 are provided on the machine table 100. The loop conveyor mechanism 120 is used for circulating and conveying the flow transfer carrier 121a. The loop conveyor mechanism 120 includes two parallel conveyor paths 121 and two transfer handling mechanisms 122. The lengths of the two conveyor paths 121 are equal, and the conveyor path 121 is parallel to the linear conveyor mechanism 110. One transfer handling mechanism 122 transports the flow transfer carrier 121a at the end of one conveyor path 121 to the head of the other conveyor path 121, and the other transfer handling mechanism 122 transports the flow transfer carrier 121a at the end of the other conveyor path 121 to the head of one conveyor path 121, so that the flow transfer carrier 121a moves along a looped trajectory continuously.

[0047] It can be understood that the conveyor path 121 includes two parallel belt conveyor mechanisms, there is a gap between the two belt conveyor mechanisms, and the flow transfer carrier 121a straddles the two belt conveyor mechanisms.

[0048] The skeleton feeding device 200 is used to feed the skeleton onto the linear conveying mechanism 110. The winding device 300 is used to wind and encapsulate the skeleton on the linear conveying mechanism 110 to obtain semi-finished products. The transfer and handling mechanism 130 is used to transfer the semi-finished products onto the flow carrier 121a. The tape inspection mechanism 400 is used to take pictures and inspect the tape on the semi-finished products to distinguish the semi-finished products with qualified encapsulation from those with unqualified encapsulation. The unqualified semi-finished product discharging mechanism is used to remove the semi-finished products with unqualified encapsulation from the flow carrier 121a. The terminal punching device 500 is used to punch terminals into the terminal slots of the skeleton of the semi-finished products with qualified encapsulation and electrically connect the terminals to the wire ends of the windings of the semi-finished products. The electrical detection mechanism 600 is used to be electrically connected to the terminals to detect the performance of the semi-finished products to distinguish good products from defective products. The flying wire cutting mechanism 700 is used to cut the flying wires wound on the wire head posts on the skeletons of the good products. The defective product discharging mechanism 800 is used to remove the defective products from the flow carrier 121a. The good product discharging device 900 is used to discharge the good products.

[0049] The linear conveying mechanism 110, the loop conveying mechanism 120 and the transfer and handling mechanism 130 are all used to transfer the skeleton. After the skeleton passes through the winding device 300, the tape inspection mechanism 400, the unqualified semi-finished product discharging mechanism, the terminal punching device 500, the electrical detection mechanism 600, the flying wire cutting mechanism 700, the defective product discharging mechanism 800 and the good product discharging device 900, an inductor with guaranteed quality can be obtained. The inductor production line can complete each step of manufacturing the inductor in sequence, with high efficiency. Moreover, the devices and mechanisms required for each step of inductor production are all concentrated on the machine table 100, making the structure of the inductor production line relatively compact and occupying relatively less space.

[0050] Referring to Figure 4 , in some of these embodiments, the terminal punching device 500 includes a reel 510, a slitting mechanism 520, a first rotary clamping mechanism 530 and a terminal punching mechanism 540. The reel 510 is used to unwind the terminal tape to the slitting mechanism 520. The slitting mechanism 520 is used to cut the terminals from the terminal tape. The first rotary clamping mechanism 530 includes a terminal jaw 531. The terminal jaw 531 is used to clamp the terminals cut by the slitting mechanism 520 and drive the terminals upward. The terminal punching mechanism 540 is used to receive the upward terminals and press the terminals down into the terminal slots of the skeleton of the semi-finished products with qualified encapsulation.

[0051] The first rotary clamping mechanism 530 further includes a first rotary cylinder 532 provided on the machine table 100 and a first horizontal linear driving mechanism 533 provided on the output end of the first rotary cylinder 532. The terminal jaw 531 is provided on the output end of the first horizontal linear driving mechanism 533.

[0052] The terminal punching device 500 further includes a rotary drive mechanism and a driven wheel, both of which are disposed on the machine table 100. A driving wheel is provided at the output end of the rotary drive mechanism. The driven wheel presses the terminal strip against the driving wheel. The driving wheel and the driven wheel clamp the terminal strip. When the rotary drive mechanism drives the driving wheel to rotate, the terminal strip can be moved towards the cutting mechanism 520.

[0053] Referring to Figures 4 to 6 , in some of the embodiments, the cutting mechanism 520 includes an anvil 521, a first support 524 disposed on the machine table 100, a first lifting drive mechanism 522 disposed on the first support 524, and a punching knife 523 disposed at the output end of the first lifting drive mechanism 522. A chute 521a is provided on the side surface of the anvil 521. The chute 521a is for the terminal strip to pass through and for the terminal gripper 531 to extend into. A through hole 521b penetrating the upper and lower surfaces of the anvil 521 is provided on the anvil 521. The chute 521a communicates with the through hole 521b. The first lifting drive mechanism 522 drives the punching knife 523 to pass through the through hole 521b from top to bottom to cut the terminal strip into individual terminals.

[0054] A limiting protrusion 521c is provided at the bottom of the chute 521a. The length direction of the chute 521a is the same as the length of the limiting protrusion 521c.

[0055] A waste collection trough 525 is provided on the machine table 100. The waste collection trough 525 is disposed below the anvil 521. The waste collection trough 525 is used to collect damaged terminals and auxiliary materials punched off from the terminal strip by the punching knife 523.

[0056] A conveying path 121, a first rotary clamping mechanism 530, and a cutting mechanism 520 are arranged in sequence. The rotation axis of the first rotary cylinder 532 is parallel to the conveying direction of the conveying path 121, so that when the first rotary cylinder 532 drives the first horizontal linear drive mechanism 533 and the terminal gripper 531 to rotate, the terminal gripper 531 can face the cutting mechanism 520 and upward.

[0057] The front end of the terminal tape unwound at the unwinding section 510 passes between the driving wheel and the driven wheel. The rotation driving mechanism drives the driving wheel to rotate, so as to drive the terminal tape to be conveyed to the chute 521a of the anvil 521. The limiting protrusion 521c can approach the limiting groove on the terminal tape, ensuring that the terminal tape moves along the length direction of the chute 521a. When the auxiliary material of the terminal tape moves to be opposite to the through hole 521b, the terminal tape stops moving. The first rotating clamping mechanism 530 drives the first horizontal linear driving mechanism 533 and the terminal claw 531 to rotate, so that the terminal claw 531 faces the opening of the chute 521a. The first horizontal linear driving mechanism 533 drives the terminal claw 531 to extend into the chute 521a. The terminal claw 531 clamps the terminal at the front end of the terminal tape. The first lifting driving mechanism 522 drives the punching knife 523 to pass through the through hole 521b from top to bottom. The punching knife 523 punches off the auxiliary material. The terminal at the front end of the terminal tape is separated from the terminal tape and is on the terminal claw 531. Then, the first horizontal linear driving mechanism 533 drives the terminal claw 531 to move away from and withdraw from the chute 521a. The first rotating clamping mechanism 530 drives the first horizontal linear driving mechanism 533 and the terminal claw 531 to rotate in the reverse direction, so that the terminal claw 531 and the terminal on the terminal claw 531 face upward.

[0058] Refer to Figure 4 and Figure 7, in some of these embodiments, the terminal pressing mechanism 540 includes a press head group 541, a second horizontal linear driving mechanism 542, and a second lifting driving mechanism 543 provided at the output end of the second horizontal linear driving mechanism 542. The press head group 541 includes a press head 541a, a conical housing 541b, a first elastic member 541c, and a suction nozzle 541d. The output end of the second lifting driving mechanism 543 faces downward and is connected to the press head 541a. The tip of the conical housing 541b faces downward. A stepped hole 541e penetrating the upper and lower surfaces of the conical housing 541b is provided on the conical housing 541b. The stepped hole 541e is larger at the top and smaller at the bottom. The lower end of the stepped hole 541e can allow a terminal to be inserted. The suction nozzle 541d communicates with the lower end of the stepped hole 541e to adsorb the terminal. The press head 541a is provided in the stepped hole 541e, and the lower end of the press head 541a can extend below the conical housing 541b and abut against the terminal. A limiting hole 541f is provided on the side surface of the conical housing 541b. The limiting hole 541f communicates with the stepped hole 541e, and the length direction of the limiting hole 541f is the up and down direction. A limiting post 541g penetrating the limiting hole 541f is provided on the press head 541a. The first elastic member 541c is provided in the stepped hole 541e and forces the conical housing 541b to move downward. The second horizontal linear driving mechanism 542 is used to drive the second lifting driving mechanism 543 and the press head group 541 to move back and forth between the first rotary clamping mechanism 530 and the skeleton on the flow carrier 121a. The second lifting driving mechanism 543 is used to drive the press head group 541 to descend, so that the terminal on the terminal jaw 531 enters the lower end of the stepped hole 541e and presses the terminal into the terminal groove.

[0059] The connection line between the loop conveyor mechanism 120 and the first rotary clamping mechanism 530 is parallel to the driving direction of the second horizontal linear driving mechanism 542. The second horizontal linear driving mechanism 542 drives the second lifting driving mechanism 543 and the press head group 541 to move back and forth between the loop conveyor mechanism 120 and the first rotary clamping mechanism 530. The second lifting driving mechanism 543 drives the press head group 541 to lift and lower, so that the press head group 541 can receive the terminal on the terminal jaw 531 and press the terminal into the terminal groove.

[0060] When the terminal punching mechanism 540 is working, the first elastic member 541c forces the conical housing 541b to move downward, the limit post 541g abuts against the top of the limit hole 541f, and the lower end of the punch head 541a retracts into the stepped hole 541e, so that the lower end of the stepped hole 541e communicates with the suction nozzle 541d. The second lifting drive mechanism 543 drives the punch head 541a and the conical housing 541b to descend simultaneously. The terminal on the terminal jaw 531 enters the lower end of the stepped hole 541e, and the suction nozzle 541d adsorbs the terminal in the lower end of the stepped hole 541e. Then, the second lifting drive mechanism 543 drives the punch head 541a and the conical housing 541b to ascend simultaneously. The second horizontal linear drive mechanism 542 drives the second lifting drive mechanism 543 and the punch head group 541 to move above the skeleton on the upstream carrier 121a of the loop conveyor mechanism 120, so that the stepped hole 541e and the terminal are aligned with the terminal slot of the skeleton. Then, the second lifting drive mechanism 543 drives the punch head 541a and the conical housing 541b to descend simultaneously. The conical housing 541b first abuts against the skeleton, the first elastic member 541c is compressed, and the conical housing 541b rises relative to the punch head 541a until the limit post 541g abuts against the bottom of the limit hole 541f. At this time, the punch head 541a extends out of the stepped hole 541e and pushes the terminal in the stepped hole 541e out of the stepped hole 541e. The terminal moves away from the suction nozzle 541d and is pressed into the terminal slot by the punch head 541a. Finally, the second lifting drive mechanism 543 drives the punch head 541a to ascend. The punch head 541a rises relative to the conical housing 541b, and the first elastic member 541c elongates. Until the limit post 541g abuts against the top of the limit hole 541f again, the punch head 541a and the conical housing 541b ascend synchronously, so that the lower end of the punch head 541a retracts into the stepped hole 541e again, and the stepped hole 541e communicates with the suction nozzle 541d.

[0061] Refer to Figure 4, the terminal punching mechanism 540 further includes a second bracket 548 disposed on the machine table 100, and the second horizontal linear driving mechanism 542 is disposed on the second bracket 548. A first mounting plate is provided at the output end of the second horizontal linear driving mechanism 542, the second lifting driving mechanism 543 is connected to the first mounting plate, a third horizontal linear driving mechanism 547 and a first cushion block 547a disposed at the output end of the third horizontal linear driving mechanism 547 are provided on the first mounting plate, and a limiting block is connected to the output end of the second lifting driving mechanism 543. The limiting block is located above the first mounting plate. After the second lifting driving mechanism 543 drives the punch head group 541 to rise, the third horizontal linear driving mechanism 547 can drive the first cushion block 547a to move so that the first cushion block 547a moves below the limiting block. When the second lifting driving mechanism 543 drives the punch head group 541 to descend, the limiting block can abut against the first cushion block 547a, and the first cushion block 547a will block the limiting block and the punch head group 541 from continuing to descend. Therefore, the first cushion block 547a can play a role in limiting the descending height of the punch head group 541. Since the skeleton has two specifications with different heights, the height of the first cushion block 547a is the height difference between the two specifications of the skeleton. When the first cushion block 547a is below the limiting block, the punch head group 541 is used to press or punch terminals into the higher-specification skeleton. When the third horizontal linear driving mechanism 547 drives the first cushion block 547a to move in the reverse direction and the first cushion block 547a avoids being below the limiting block, the punch head group 541 is used to press or punch terminals into the lower-specification skeleton.

[0062] In some of these embodiments, the terminal punching mechanism 540 further includes a third lifting driving mechanism 544, a top plate 545, a fifth horizontal linear driving mechanism 546, and a second cushion block 546a. The output end of the third lifting driving mechanism 544 is connected to the top plate 545. The top plate 545 is used to lift the flow-carrying tool 121a on the loop conveying mechanism 120 to position the skeleton on the flow-carrying tool 121a. The output end of the fifth horizontal linear driving mechanism 546 is connected to the second cushion block 546a. The fifth horizontal linear driving mechanism 546 is used to drive the second cushion block 546a to move below the top plate 545 to position the top plate 545 above the loop conveying mechanism 120.

[0063] When the third lifting driving mechanism 544 drives the top plate 545 to rise, the top plate 545 will lift the flow-carrying tool 121a on the loop conveying mechanism 120, and the flow-carrying tool 121a will be separated from the loop conveying mechanism 120. The loop conveying mechanism 120 will not be able to continue driving the flow-carrying tool 121a to move, realizing the positioning of the flow-carrying tool 121a and the skeleton thereon, so that the punch head group 541 can press the terminals into the terminal slots of the skeleton.

[0064] When the top plate 545 rises, the fifth horizontal linear driving mechanism 546 drives the second cushion block 546a to move below the top plate 545. The top plate 545 can abut against the second cushion block 546a. When the terminal pressing head group 541 presses the terminal into the terminal groove, the top plate 545 is subjected to a downward pressing force, and the second cushion block 546a can prevent the top plate 545 from moving downward.

[0065] Referring to Figure 4 , the terminal pressing mechanism 540 further includes a fourth horizontal linear driving mechanism 549 provided on the machine table 100. The driving direction of the fourth horizontal linear driving mechanism 549 is parallel to the conveying direction of a conveying channel 121. The output end of the fourth horizontal linear driving mechanism 549 is connected to the third lifting driving mechanism 544. The fourth horizontal linear driving mechanism 549 drives the third lifting driving mechanism 544 to move in the conveying direction of a conveying channel 121, so as to adjust the positions of the third lifting driving mechanism 544, the top plate 545 and the flow transfer carrier 121a in the conveying direction of a conveying channel 121, and ensure that the skeleton on the flow transfer carrier 121a is exactly below the terminal pressing head group 541.

[0066] The output end of the fourth horizontal linear driving mechanism 549 is connected with a second mounting plate. The fifth horizontal linear driving mechanism 546 and the second cushion block 546a are both arranged on the second mounting plate, and the top plate 545 can abut against the upper surface of the second mounting plate.

[0067] Referring to Figure 1 、 Figure 8 and Figure 9 , in some of the embodiments, the skeleton feeding device 200 includes a first feeding mechanism 210, a transfer conveying mechanism 220, a skeleton detection mechanism 230 and a second feeding mechanism 240. A transfer carrier 221 is provided on the transfer conveying mechanism 220, and a rotatable support seat 221a is provided on the transfer carrier 221. The first feeding mechanism 210 is used to carry the skeleton onto the support seat 221a. The transfer conveying mechanism 220 conveys the skeleton on the support seat 221a to an area close to the skeleton detection mechanism 230. The skeleton detection mechanism 230 takes pictures of the skeleton to identify the position of the terminal groove on the skeleton. The support seat 221a can rotate to adjust the position of the terminal groove on the skeleton. A conveying carrier 111 is provided on the linear conveying mechanism 110. The second feeding mechanism 240 is used to carry the skeleton on the support seat 221a onto the conveying carrier 111.

[0068] The first loading mechanism 210 transports the skeleton to the support seat 221a of the intermediate conveyor 221 of the intermediate conveying mechanism 220. The intermediate conveying mechanism 220 transports the intermediate conveyor 221 and the skeleton on the intermediate conveyor 221 to an area close to the skeleton detection mechanism 230. The skeleton detection mechanism 230 takes a picture of the skeleton to distinguish the position of the terminal slot on the skeleton. When the position of the terminal slot on the skeleton does not meet the specified requirements, the support seat 221a rotates to complete the adjustment of the position of the terminal slot on the skeleton so that the position of the terminal slot on the skeleton meets the specified requirements. Then the second loading mechanism 240 transports the skeleton on the support seat 221a to the conveying carrier 111, so that the position of the terminal slot on the skeleton cooperates with the conveying carrier 111, and the skeleton can be accurately limited on the conveying carrier 111, so that the skeleton can be transported to the area corresponding to the winding device 300 and the transfer and conveying mechanism 130 in an accurate posture, so that the winding device 300 can wind the skeleton, and the transfer and conveying mechanism 130 can accurately grasp the skeleton and place the skeleton on the circulation conveyor 121a in a specific posture.

[0069] Reference Figure 9 In some embodiments, the intermediate transfer tool 221 is provided with a first in-place sensor 221b, a second in-place sensor 221c and a third in-place sensor 221d. The heights of the first in-place sensor 221b, the second in-place sensor 221c and the third in-place sensor 221d are successively reduced. The third in-place sensor 221d is used to detect the detection port of the skeleton to confirm whether the skeleton falls in the correct position of the support seat 221a. The first in-place sensor 221b and the second in-place sensor 221c are respectively used to detect inductors of two different height specifications.

[0070] When the skeleton falls on the correct position of the support base 221a, the third in-place sensor 221d can sense a signal, the first in-place sensor 221b can sense a signal, proving that the skeleton on the support base 221a is of a higher specification, and the second in-place sensor 221c can sense a signal, proving that the skeleton on the support base 221a is of a lower specification.

[0071] Reference Figure 10 and Figure 11 In some embodiments, the conveying carrier 111 includes multiple groups of clamping arms, and a second elastic member is provided between two clamping arms of a group of clamping arms. The second elastic member forces the two clamping arms to approach each other to clamp the skeleton. The machine 100 is provided with an opening clamping jaw 140 in the area corresponding to the second loading mechanism 240. The opening clamping jaw 140 is used to open the two clamping arms so that the skeleton can enter or exit between the two clamping arms.

[0072] When the second feeding mechanism 240 positions the skeleton right in between the two clamping arms, the unclamping jaws 140 expand the two clamping arms, enabling the skeleton to enter the area between the two clamping arms and be clamped by the two clamping arms. The unclamping jaws 140 are provided in the area corresponding to where the skeleton needs to be removed, such as in two areas on the machine table 100 corresponding to the winding device 300 and the transfer handling mechanism 130. The unclamping jaws 140 expand the two clamping arms, allowing the skeleton to be removed from the two clamping arms.

[0073] Referring Figure 10 , in some of these embodiments, the second feeding mechanism 240 includes a sixth horizontal linear driving mechanism 241, a fourth lifting driving mechanism 242, a second rotary cylinder 243, and a first skeleton gripper 244. The output end of the sixth horizontal linear driving mechanism 241 is connected to the fourth lifting driving mechanism 242, the output end of the fourth lifting driving mechanism 242 is connected to the second rotary cylinder 243, and the output end of the second rotary cylinder 243 is connected to the first skeleton gripper 244.

[0074] The second feeding mechanism 240 further includes a third support 245. The sixth horizontal linear driving mechanism 241 is provided on the third support 245. The conveying directions of the intermediate transfer conveying mechanism 220 and the linear conveying mechanism 110 are parallel to each other, and the driving direction of the sixth horizontal linear driving mechanism 241 is perpendicular to the conveying direction of the linear conveying mechanism 110. The rotation axis of the second rotary cylinder 243 is parallel to the conveying direction of the intermediate transfer conveying mechanism 220. The second rotary cylinder 243 can drive the first skeleton gripper 244 to rotate, changing the posture of the skeleton from an upright posture on the intermediate transfer carrier 221 to a lying state on the conveying carrier 111.

[0075] It can be envisioned that the structure of the transfer handling mechanism 130 is similar to that of the second feeding mechanism 240. The transfer handling mechanism 130 transports the semi-finished product in a lying state on the conveying carrier 111 to the flow transfer carrier 121a, and the skeleton on the flow transfer carrier 121a is in an upright posture.

[0076] Referring Figure 12 , in some of these embodiments, the good product discharging device 900 includes a seventh horizontal linear driving mechanism 910, a fifth lifting driving mechanism 920, an eighth horizontal linear driving mechanism 930, a good product gripper 940, and a discharging conveyor belt 950.

The driving directions of the fifth lifting driving mechanism 920 and the eighth horizontal linear driving mechanism 930 are perpendicular to each other, and the discharging conveyor belt 950 is used to collect and output good products.

[0077] The seventh horizontal linear driving mechanism 910, the fifth lifting driving mechanism 920, the eighth horizontal linear driving mechanism 930 and the good product gripper 940 can realize transporting the good products on the flow transfer carrier 121a to the blanking conveyor belt 950.

[0078] The good product blanking device 900 further includes a fourth support 960 provided on the machine table 100, and the seventh horizontal linear driving mechanism 910 is provided on the fourth support 960.

[0079] Refer to Figure 12 , in some of the embodiments, the inductor production line further includes a wire pulling mechanism. The wire pulling mechanism includes a wire gripper 961 provided on the fourth support 960 and a wire collection groove 962 provided on the machine table 100. The wire gripper 961 is located above the wire collection groove 962.

[0080] The seventh horizontal linear driving mechanism 910, the fifth lifting driving mechanism 920, the eighth horizontal linear driving mechanism 930 and the good product gripper 940 can realize transporting the good products on the flow transfer carrier 121a to the front of the wire gripper 961. The wire gripper 961 clamps the wire on the wire column of the skeleton. Then, the seventh horizontal linear driving mechanism 910, the fifth lifting driving mechanism 920, the eighth horizontal linear driving mechanism 930 and the good product gripper 940 move the good products forward from the wire gripper 961, so that the wire falls off the wire column. The wire gripper 961 releases the wire, and the wire can fall into the wire collection groove 962. Finally, the seventh horizontal linear driving mechanism 910, the fifth lifting driving mechanism 920, the eighth horizontal linear driving mechanism 930 and the good product gripper 940 transport the good products after the wire is pulled out to the blanking conveyor belt 950.

[0081] It can be imagined that the skeleton is placed on a tray. The first loading mechanism 210 includes a second skeleton gripper. The second skeleton gripper can move in three-dimensional space, and the second skeleton gripper transports the skeleton on the tray to the support seat 221a of the intermediate transfer carrier 221.

[0082] It should be understood that the intermediate transfer mechanism 122 includes a flow transfer carrier gripper for clamping the flow transfer carrier 121a. The flow transfer carrier gripper has the functions of lifting and translation, and the translation direction of the flow transfer carrier gripper is perpendicular to the conveying direction of the conveying channel 121. The skeleton detection mechanism 230 and the tape inspection mechanism 400 are both CCD detection mechanisms. The rotation driving mechanism is a motor. Other devices and mechanisms and other components not specifically described are common components on the market, and their structures, functions, and general usage methods are known, and no redundant introduction is made here.

For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described.
