At the same time, the second X-axis drive assembly 320 drives the second positioning jig 310 to move backward and reset, so as to position and accommodate the next batch of skeletons with soldered pins.

[0067] As an embodiment of the present invention, refer to Figure 3 and Figure 4 The semi-finished transformer production line also includes a cooling mechanism 500, which is arranged between the soldering mechanism 200 and the insertion mechanism 600. The cooling mechanism 500 is used to reduce the temperature of the tin liquid attached to the skeleton pins to accelerate the solidification of the tin liquid attached to the skeleton pins. It can be understood that by setting the cooling mechanism 500, the solidification of the tin liquid on the skeleton pins can be accelerated, and the unsolidified tin liquid can be prevented from affecting the subsequent insertion processing, which is conducive to improving the yield rate of the finished transformer. The cooling mechanism 500 can be a cold air blower that blows air downward. During the forward movement of the second positioning fixture 310, it will pass under the cold air blower, thereby accelerating the solidification of the tin liquid.

[0068] refer to Figure 7 and Figure 8 The second clamping and transporting mechanism 700 in the embodiment of the present invention includes a second XYZ axis driving assembly 710 and a plurality of second expansion shafts 720 distributed along the front-to-back direction, the plurality of second expansion shafts 720 are parallel to the left-to-right direction, the plurality of second expansion shafts 720 are parallel to each other, and the first expansion shaft 430 has the same structure as the second expansion shaft 720. The number of the second expansion shafts 720 is the same as the number of the first expansion shafts 430. The second XYZ axis driving assembly 710 is used to drive the plurality of second expansion shafts 720 to move along the X-axis direction, the Y-axis direction, and the Z-axis direction (i.e., the front-to-back direction, the left-to-right direction, and the up-down direction). It can be understood that after the second X-axis drive assembly 320 drives the second positioning fixture 310 to approach the insertion mechanism 600, the second XYZ-axis drive assembly 710 drives the multiple second expansion shafts 720 to move backward, so that the multiple second expansion shafts 720 are respectively aligned with the second avoidance grooves on the side walls of the multiple second positioning grooves, and then the second XYZ-axis drive assembly 710 drives the multiple second expansion shafts 720 to move to the right, so that the multiple second expansion shafts 720 are respectively inserted into the second avoidance grooves on the side walls of the multiple second positioning grooves, and respectively extend into the through holes of the multiple skeletons and then expand and clamp the multiple skeletons; after the skeletons are clamped, the second XYZ-axis drive assembly 710 drives the skeletons on the multiple second expansion shafts 720 to move to the insertion mechanism 600 for metal sheet insertion.

[0069] refer to Figures 7 to 11 The insertion mechanism 600 includes a first feeding component 610, a clamping rotation component 620, a first clamping component 630, a first transverse driving component 640 and a first lifting driving component 650. The first feeding component 610 is used to accommodate and convey the metal sheet from left to right. The clamping rotation component 620 is used to clamp the metal sheet at the discharge end of the first feeding component 610 and drive the metal sheet to rotate 90° so that the insertion end of the metal sheet faces downward. The first clamping component 630 is used to clamp the metal sheet on the clamping rotation component 620. The first transverse driving component 640 is used to drive the first clamping component 630 to move in the left and right directions so that the insertion end of the metal sheet on the first clamping component 630 is aligned with the insertion hole on the skeleton on the second clamping and transporting mechanism 700. The first lifting driving component 650 can drive the first clamping component 630 to descend so that the insertion end of the metal sheet is inserted into the insertion hole on the skeleton.

[0070] It can be understood that after the second XYZ-axis driving assembly 710 drives the multiple second tensioning shafts 720 and the skeletons on the multiple second tensioning shafts 720 to move to the bottom of the first clamping assembly 630, the clamping rotating assembly 620 clamps the metal sheet at the discharge end of the first feeding assembly 610, and then the clamping rotating assembly 620 drives the metal sheet to rotate upward 90° so that the insertion end of the metal sheet faces downward; then the first lateral driving assembly 640 drives the first clamping assembly 630 to move to the left, and the first lifting driving assembly 650 drives the first clamping assembly 630 to move downward, so that the first clamping assembly 630 can clamp the metal sheet clamped by the clamping rotating assembly 620; then the clamping rotating assembly 620 releases the metal sheet, the first lifting drive assembly 650 drives the first clamping assembly 630 to rise, and then the first lateral drive assembly 640 drives the first clamping assembly 630 to move to the right, so that the insertion end of the metal sheet on the first clamping assembly 630 can be aligned with the insertion hole of the skeleton on the second expansion shaft 720; finally, the first lifting drive assembly 650 drives the first clamping assembly 630 to descend, so that the insertion end of the metal sheet can be inserted into the insertion hole on the skeleton to complete the insertion of the skeleton. In the present invention, the insertion mechanism 600 inserts one metal sheet on the skeleton at a time, and then the second XYZ axis driving assembly 710 drives multiple second expansion shafts 720 to move forward according to a preset frequency, so that the insertion mechanism 600 inserts another metal sheet on the skeleton, and then the skeletons on multiple second expansion shafts 720 are all inserted with two metal sheets.

[0071] refer to Fig. 9 and Fig.10The clamping rotation assembly 620 includes a first clamping cylinder 622, a rotating drive member 621 and two first clamping blocks 623. First limiting grooves 624 are provided on two opposite sides of the two first clamping blocks 623. The two output ends of the first clamping cylinder 622 are respectively connected to the two first clamping blocks 623. The first clamping cylinder 622 can drive the two first clamping blocks 623 to approach each other so that a partial structure of the metal sheet at the discharge end of the first feeding assembly 610 is arranged in the two first limiting grooves 624, and the inner walls of the two first limiting grooves 624 clamp the metal sheet. The output end of the rotating drive member 621 is connected to the first clamping cylinder 622. The rotating drive member 621 can drive the first clamping cylinder 622 to rotate 90° so that the insertion end of the metal sheet faces downward. It can be understood that first limiting grooves 624 are provided on two opposite sides of the two first clamping blocks 623, and a partial structure of the metal sheet can be arranged in the two first limiting grooves 624, so that the inner walls of the two first limiting grooves 624 play a role in positioning and limiting the metal sheet, thereby enabling the metal sheet to be in a correct posture after rotating 90°, ensuring that the subsequent metal sheet can be smoothly inserted into the insertion hole on the frame. Specifically, the partial structure of the metal sheet is the lower half structure of the metal sheet.

[0072] refer to Fig. 9 and Fig.11 The first feeding assembly 610 includes a first feeding track 611, which is used to accommodate multiple metal sheets and convey the metal sheets from left to right. The first feeding track 611 is provided with a sorting auxiliary assembly 660, which is used to sort the multiple metal sheets on the first feeding track 611 and make the multiple metal sheets extend out of the discharge end of the first feeding track 611 in sequence, so that the metal sheets extending out of the discharge end of the first feeding track 611 can be set in the two first limiting grooves 624. It can be understood that the sorting auxiliary assembly 660 can sort the multiple metal sheets on the first feeding track 611 and make the multiple metal sheets extend out of the discharge end of the first feeding track 611 in sequence. The sorting auxiliary component 660 ensures that the remaining metal sheets will not fall from the discharge end of the first feeding track 611 when the two first clamping blocks 623 are clamping a metal sheet. On the other hand, it allows the metal sheet to be arranged in the two first limiting grooves 624, so that the two first clamping blocks 623 can accurately clamp the metal sheet, which is beneficial to improving the accuracy of subsequent metal sheet insertion.

[0073] refer to Fig.11The sorting auxiliary component 660 includes a first cylinder 661, a second cylinder 662, a third cylinder 663 and a fourth cylinder 664. The piston rod of the first cylinder 661 can be extended and abutted against the first metal sheet on the right side of the first feeding track 611, so that the multiple metal sheets on the first feeding track 611 are arranged in order. The piston rod of the second cylinder 662 can be extended and penetrated into the through hole on the second metal sheet on the right to block the multiple metal sheets on the left side of the first metal sheet from moving to the right. The piston rod of the third cylinder 663 can be extended and penetrated into the through hole on the first metal sheet. At this time, the piston rod of the first cylinder 661 contracts and disengages from the abutment with the first metal sheet. The fourth cylinder 664 can drive the third cylinder 663 to move to the right, so that the piston rod of the third cylinder 663 drives the first metal sheet to move to the right and extend out of the discharge end of the first feeding track 611. The first feeding track 611 is parallel to the left-right direction, and the right end of the first feeding track 611 is the discharging end of the first feeding track 611 , and is also the discharging end of the first feeding assembly 610 .

[0074] For the convenience of explanation, the multiple metal sheets on the first feeding track 611 are defined as the first metal sheet and the second metal sheet from right to left, and so on. The first feeding track 611 transports multiple metal sheets from left to right. At this time, the piston rod of the first cylinder 661 extends and can abut against the first metal sheet. The piston rod of the first cylinder 661 prevents the first metal sheet from moving to the right. After a period of time, the multiple metal sheets on the first feeding track 611 are closely attached to each other, so that the multiple metal sheets are arranged in order along the left and right directions. Then the piston rod of the second cylinder 662 extends, and the piston rod of the second cylinder 662 is inserted into the through hole on the second metal sheet. At the same time, the piston rod of the third cylinder 663 then extends, and the piston rod of the third cylinder 663 is inserted into the through hole on the first metal sheet. Finally, the piston rod of the first cylinder 661 contracts, the piston rod of the first cylinder 661 is separated from the contact with the first metal sheet, and then the piston rod of the fourth cylinder 664 extends, and the piston rod of the fourth cylinder 664 drives the third cylinder 663 to move to the right. Driven by the piston rod of the third cylinder 663, the first metal sheet extends out of the discharge end of the first feeding track 611, and under the blocking effect of the piston rod of the second cylinder 662, the multiple metal sheets to the left of the first metal sheet will not move to the right. The extension distance of the piston rod of the fourth cylinder 664 can be adjusted according to actual needs, so that the length of the first metal sheet extending out of the discharge end of the first feeding track 611 can be just aligned with the first limiting grooves 624 on the two first clamping blocks 623, so that after the two first clamping blocks 623 are close to each other, the partial structure of the metal sheet can be accurately set in the two first limiting grooves 624. After the partial structure of the metal sheet is arranged in the two first limiting grooves 624 , the piston rod of the third cylinder 663 contracts so that the two first clamping blocks 623 can clamp the first metal sheet away.

[0075] After the two first clamping blocks 623 clamp the first metal sheet away, the piston rod of the second cylinder 662 contracts and the piston rod of the first cylinder 661 extends. Under the action of the first feeding track 611, the multiple metal sheets start to move from left to right again, and then the new first metal sheet abuts against the piston rod of the first cylinder 661, and the piston rod of the second cylinder 662 extends and penetrates the through hole on the new second metal sheet. The above process is repeated, so that the multiple metal sheets extend out of the discharge end of the first feeding track 611 in turn, and then the two first clamping blocks 623 clamp the multiple first metal sheets in turn. The sorting auxiliary component 660 also includes an incoming material sensor 665, which can detect whether the first metal sheet is in place, so that the first cylinder 661, the second cylinder 662, the third cylinder 663 and the fourth cylinder 664 complete the corresponding action.

[0076] refer to Fig. 9 and Fig.10 The first clamping assembly 630 includes a second clamping cylinder 631 and two second clamping blocks 632. Second limiting grooves 633 are provided on two opposite side surfaces of the two second clamping blocks 632. The two output ends of the second clamping cylinder 631 are respectively connected to the two second clamping blocks 632. The second clamping cylinder 631 can drive the two second clamping blocks 632 to approach each other so that another part of the metal sheet on the two first clamping blocks 623 is arranged in the two second limiting grooves 633, and the inner walls of the two second limiting grooves 633 clamp the metal sheet. It can be understood that the two second clamping blocks 632 are provided with second limiting grooves 633 on the two opposite sides, and another part of the structure of the metal sheet can be arranged in the two second limiting grooves 633, so that the inner walls of the two second limiting grooves 633 play a role in positioning and limiting the metal sheet, so that after the two second clamping blocks 632 clamp the metal sheet, the metal sheet can be in a correct posture, ensuring that the insertion end of the metal sheet can be aligned with the insertion hole on the skeleton, which is conducive to improving the insertion accuracy of the metal sheet. Specifically, the other part of the structure of the metal sheet is the upper half structure of the metal sheet. In the embodiment of the present invention, there are two insertion mechanisms 600, and the two insertion mechanisms 600 are arranged along the front-to-back direction, and the two insertion mechanisms 600 can be inserted at the same time.

[0077] The third positioning and conveying mechanism in the embodiment of the present invention includes a third positioning fixture 810 and a third X-axis driving assembly 820. The output end of the third X-axis driving assembly 820 is connected to the third positioning fixture 810, and the third X-axis driving assembly 820 can drive the third positioning fixture 810 to move along the X-axis direction (i.e., the front-back direction). The structure of the third positioning fixture 810 is the same as that of the first positioning fixture 110. After all the skeletons on the multiple second expansion shafts 720 are inserted (i.e., two metal sheets are inserted on one skeleton), the second XYZ axis driving assembly 710 drives the multiple second expansion shafts 720 to move forward, so that the multiple second expansion shafts 720 are located above the third positioning fixture 810, and then the second XYZ axis driving assembly 710 drives the multiple second expansion shafts 720 to descend, and then the multiple second expansion shafts 720 contract and loosen the multiple skeletons respectively, so that the multiple skeletons are placed on the third positioning fixture 810, so that the third positioning fixture 810 is positioned to accommodate the multiple inserted skeletons. Finally, the third X-axis driving assembly 820 drives the third positioning fixture 810 and the multiple skeletons on the third positioning fixture 810 to move forward, so that the multiple skeletons move to the detection mechanism 900 for detection.

[0078] It should be explained that the two metal sheets inserted into the frame are respectively in contact with the two pins on the frame. Fig.12 The detection mechanism 900 of the embodiment of the present invention includes a conductive detection member 910 and a second Y-axis driving assembly 920. The conductive detection member 910 is provided with two contact heads that can abut against two metal sheets on the frame. The conductive detection member 910 is electrically connected to the third clamping and transporting mechanism 1000. The second Y-axis driving assembly 920 is used to drive the conductive detection member 910 to move along the Y-axis direction (i.e., the left and right direction). After the third X-axis driving assembly 820 drives the third positioning fixture 810 to move to the right of the conductive detection member 910, the second Y-axis driving assembly 920 drives the conductive detection member 910 to move to the right, so that the two contact heads are respectively in contact with the two metal sheets on the frame. When the two pins on the frame are in the conductive state (i.e., the frame is qualified), the conductive detection member 910 is triggered and transmits the first signal to the third clamping and transporting mechanism 1000, and the third clamping and transporting mechanism 1000 transports the qualified frame to the shell mechanism 1100; when the two pins on the frame are in the disconnected state (i.e., the frame is unqualified), the conductive detection member 910 cannot be triggered and transmits the second signal to the third clamping and transporting mechanism 1000, and the third clamping and transporting mechanism 1000 transports the unqualified frame to the first material collection mechanism 1300. The third X-axis driving assembly 820 drives the third positioning fixture 810 to move forward at a preset frequency, so that the conductive detection member 910 sequentially detects multiple frames on the third positioning fixture 810. There are two detection mechanisms 900, and the two detection components are distributed along the front-to-back direction. The two detection components can detect the skeleton at the same time.

[0079] refer to Fig.12 The third clamping and transporting mechanism 1000 in the embodiment of the present invention includes a third XZ-axis driving assembly 1010 and a third clamping cylinder 1020. The third clamping cylinder 1020 is used to clamp the skeleton on the third positioning fixture 810. The third XZ-axis driving assembly 1010 is used to drive the third clamping cylinder 1020 to move along the X-axis direction and the Z-axis direction (i.e., the front-to-back direction and the up-down direction). After the third XZ-axis driving assembly 1010 receives the signal from the conductive detection component 910, the third XZ-axis driving assembly 1010 drives the third clamping cylinder 1020 to move to the top of the third positioning fixture 810, and then the third XZ-axis driving assembly 1010 drives the third clamping cylinder 1020 to descend, and the third clamping cylinder 1020 clamps the skeleton after the detection is completed; after the third clamping cylinder 1020 completes the clamping, the third XZ-axis driving assembly 1010 drives the third clamping cylinder 1020 to first rise and then move forward, so that the third clamping cylinder 1020 moves to the shell mechanism 1100 or the first material collecting mechanism 1300, and finally the third XZ-axis driving assembly 1010 drives the third clamping cylinder 1020 to descend, and the third clamping cylinder 1020 releases the skeleton, thereby placing the skeleton at the shell mechanism 1100 or the first material collecting mechanism 1300.

[0080] refer to Fig.12 The first material collecting mechanism 1300 includes a second transverse driving assembly 1310, a material plate 1320, a push plate 1330 and a collection box. The material plate 1320 is parallel to the left and right directions. The material plate 1320 is used to accommodate the skeleton with the pins in a disconnected state transported by the third clamping and transporting mechanism 1000. The push plate 1330 is used to abut against the skeleton on the material plate 1320. The collection box is arranged below the left end of the material plate 1320. The second transverse driving assembly 1310 is used to drive the push plate 1330 to move along the left and right directions, so that the push plate 1330 can push the skeleton on the material plate 1320 to move to the left and make the skeleton fall into the collection box. It can be understood that the third clamping cylinder 1020 places the unqualified skeleton at the right end of the material plate 1320, and then the second transverse drive assembly 1310 drives the push plate 1330 to push the skeleton to the left a distance, so that the right end of the material plate 1320 is vacant, and then the third clamping cylinder 1020 places the next unqualified skeleton at the right end of the material plate 1320, and so on. When the material plate 1320 is full of unqualified skeletons, the second transverse drive assembly 1310 drives the push plate 1330 to push the skeleton to the left, so that the unqualified skeletons on the material plate 1320 fall into the collection box, which is convenient for subsequent operators to centrally process the unqualified skeletons in the collection box.

[0081] refer to Fig.13The casing mechanism 1100 in the embodiment of the present invention includes a second feeding assembly 1110, a fourth clamping cylinder 1120, a first YZ axis driving assembly, a fourth positioning fixture 1140 and a fourth X axis driving assembly 1150. The second feeding assembly 1110 is used to accommodate the shell and transport the shell from left to right, the first YZ axis driving assembly is used to drive the fourth clamping cylinder 1120 to move along the Y axis direction and the Z axis direction (i.e., the left and right direction and the up and down direction), the fourth X axis driving assembly 1150 is used to drive the fourth positioning fixture 1140 to move along the X axis direction (i.e., the front and back direction), and the fourth positioning fixture 1140 is provided with a fourth positioning groove, the fourth positioning groove is used to accommodate the skeleton so that the two metal sheets on the skeleton face upward, and the left and right side walls of the fourth positioning groove are provided with fourth avoidance grooves, and the two fourth avoidance grooves are used for the two output ends of the fourth clamping cylinder 1120 to pass through. It can be understood that the first YZ-axis drive assembly drives the fourth clamping cylinder 1120 to move to the discharge end of the second feeding assembly 1110, so that the fourth clamping cylinder 1120 clamps the shell at the discharge end of the second feeding assembly 1110; after the fourth clamping cylinder 1120 clamps the shell, the first YZ-axis drive assembly drives the fourth clamping cylinder 1120 to move above the fourth positioning fixture 1140, and then the first YZ-axis drive assembly drives the fourth clamping cylinder 1120 to descend, so that the fourth clamping cylinder 1120 installs the clamped shell on the skeleton in the fourth positioning groove to obtain a semi-finished transformer. Then the fourth X-axis drive assembly 1150 drives the fourth positioning fixture 1140 to move forward, so that the fourth clamping and transporting mechanism 1200 transports the semi-finished transformer on the fourth positioning fixture 1140 to the second material collection mechanism 1400.

[0082] refer to Fig.13As an embodiment of the present invention, the shell mechanism 1100 also includes a fifth positioning fixture 1160 and a fifth X-axis drive assembly 1170. The fifth positioning fixture 1160 is provided with a fifth positioning groove, and the fifth positioning groove is used to accommodate the shell. The fifth X-axis drive assembly 1170 is used to drive the fifth positioning fixture 1160 to move along the X-axis direction (i.e., the front and rear direction), so that the shell at the discharge end of the second feeding assembly 1110 enters the fifth positioning groove, or the fifth positioning fixture 1160 closes the discharge end of the second feeding assembly 1110. It can be understood that after the shell at the discharge end of the second feeding component 1110 enters the fifth positioning groove, the fifth X-axis drive assembly 1170 drives the fifth positioning fixture 1160 to move backward, so that the single shell follows the fifth positioning fixture 1160 away from the discharge end of the second feeding component 1110, and the fifth positioning fixture 1160 closes the discharge end of the second feeding component 1110, and finally the fourth clamping cylinder 1120 clamps the shell on the fifth positioning fixture 1160. Then the fifth X-axis drive assembly 1170 drives the fifth positioning fixture 1160 to move forward, so that the next single shell enters the fifth positioning groove. By setting the fifth positioning fixture 1160 and the fifth X-axis drive assembly 1170, the second feeding component 1110 can be prevented from affecting the shell, and the clamping accuracy of the fourth clamping cylinder 1120 clamping the shell is improved, so that the subsequent shell can be accurately installed on the skeleton.

[0083] refer to Fig.14 The fourth clamping and transporting mechanism 1200 of the embodiment of the present invention includes a fourth XZ-axis driving assembly 1220 and a fifth clamping cylinder 1210. The fourth XZ-axis driving assembly 1220 is used to drive the fifth clamping cylinder 1210 to move along the X-axis direction and the Z-axis direction (i.e., the front-to-back direction and the up-down direction), and the fifth clamping cylinder 1210 is used to clamp the semi-finished transformer on the fourth positioning fixture 1140. It can be understood that after the fourth X-axis driving assembly 1150 drives the fourth positioning fixture 1140 to approach the second material collecting mechanism 1400, the fourth XZ-axis driving assembly 1220 drives the fifth clamping cylinder 1210 to move to the fourth positioning fixture 1140. After the fifth clamping cylinder 1210 clamps the semi-finished transformer on the fourth positioning fixture 1140, the two output ends of the fifth clamping cylinder 1210 can be respectively arranged in the two fourth avoidance grooves; finally, the semi-finished transformer is transported to the second material collecting mechanism 1400.

[0084] refer to Fig.14The second material collecting mechanism 1400 of the embodiment of the present invention includes a third Y-axis driving assembly 1410 and a material box 1420. The material box 1420 is used to accommodate the semi-finished transformer. The third Y-axis driving assembly 1410 is used to drive the material box 1420 to move along the Y-axis direction (i.e., the left-right direction). After the fifth clamping cylinder 1210 clamps the semi-finished transformer, the fourth XZ-axis driving assembly 1220 drives the fifth clamping cylinder 1210 to move above the material box 1420, and then the fourth XZ-axis driving assembly 1220 drives the fifth clamping cylinder 1210 to descend, and the fifth clamping cylinder 1210 releases the semi-finished transformer, so that the semi-finished transformer is placed in the material box 1420. With the cooperation of the fourth XZ-axis driving assembly 1220 and the third Y-axis driving assembly 1410, the semi-finished transformer placed in the material box 1420 can be distributed in a rectangular array or other ways, so that the subsequent processing equipment can load and grab the neatly arranged semi-finished transformers in the material box 1420.

[0085] In the present invention, the first feeding assembly 610 further includes a first circular vibration feeder and a first vibration motor.
