[0043] An optical sensor is also vertically arranged on the top of the base, and the optical sensor is located below the rotating disk. The optical sensor is used to sense whether there is a shell in the clamping mechanism at the eighth position.

[0044] Compared with the prior art, the present invention provides an assembly system for a current sensor. During assembly, first, a plurality of shells are placed on a support tray (the incoming materials are placed in the placement state), and the support tray is located on a tray plate. Then, the first driving mechanism drives the first pneumatic clamp to take out a shell on the support tray, and put the shell on the clamping mechanism at the first position (where the first position in this application is the position where the shell is initially placed, and then the second position, the third position, and so on are rotated counterclockwise); before placing the shell, the unlocking mechanism at the first position unlocks the clamping mechanism, and when the shell is placed, the unlocking mechanism is moved away, so that the clamping mechanism fixes and clamps the shell.

[0045] After that, the motor drives the rotating disk to rotate 45 degrees (45 degrees each time). At this position, the separation rod is raised and inserted into the hole at the bottom of the shell; then the separation rod moves outward, driving the elastic arm to separate from the shell (most of the elastic arms and the shell in the incoming materials are in a separated state, but some are fastened during transportation) until the separation rod is separated from the shell, and the separation rod is reset after it drops and waits for the next action.

[0046] The rotating disk rotates again, and here a chip is first engaged in the adsorption slot at the end of the adsorption seat (when engaging, the chip can be sent to the adsorption slot by a worker, or the chip can be sent one by one to the position where the adsorption seat can act on it using a vibration disk, or there can be a visual picking robot under the adsorption seat, which has a pneumatic clamp. After each visual photo is taken, a chip is taken out from the chip disk and the pins are clamped. Then the robot moves the pneumatic clamp to clamp the corresponding pins and moves the chip shell to the adsorption seat, so that the chip can be engaged in the adsorption slot; or it can be the combined action of the vibration disk and the robot, that is, the pneumatic clamp on the robot removes the chip from the feeding track of the vibration disk and sends the chip into the adsorption slot); after the chip is engaged in the adsorption slot, the exhaust fan connected to the negative pressure hole generates negative pressure, so that the chip can not only be engaged in the adsorption slot, but also fit in the adsorption slot.

[0047] Then the third driving mechanism moves the chip, and makes the chip below and the pin above, and at the same time makes the chip above the hole above the shell; at this time, the negative pressure in the negative pressure hole disappears, but the position of the adsorption seat does not move, and the periphery of the chip is limited by the shell and the adsorption groove, so that the position of the chip can be temporarily maintained; then the pressing piece moves downward, pressing the pin downward, pressing the chip into the hole above the shell, and at the same time making the bent pin able to be stuck in the slot on the top of the shell, and at the same time the slot and the pin have an interference fit.

[0048] After the rotating disk rotates again, the unlocking mechanism at the fourth position first unlocks the clamping mechanism, and then the fourth driving mechanism drives the second pneumatic clamp to move. After clamping the shell, it is raised and rotated 180 degrees, and finally lowered to the clamping mechanism. The unlocking mechanism is released, and the shell is fixed on the clamping mechanism again, and the hole below is located above.

[0049] The rotating disk rotates again, and the third pneumatic clamp, driven by the fifth driving mechanism, takes out a U-shaped magnetic core with its opening facing downward from the magnetic support disk, and slightly inserts the bottom of the magnetic core into the hole above the shell (the third pneumatic clamp clamps the top of the magnetic core so that its bottom can be inserted into the shell first); then the third pneumatic clamp releases the magnetic core, and the consolidation rod presses downward to fully press the magnetic core into the shell.

[0050] The rotating disk rotates again, and the closing rod, under the driving action of the sixth driving mechanism, pushes the free end of the elastic arm inward, and makes the elastic arm engage with the shell. At this time, the protrusion on the inner side of the elastic arm can limit the outer side of the magnetic core, and can fully limit the magnetic core.

[0051] After the rotating disk rotates, the unlocking mechanism at the seventh position releases the clamping mechanism, and the fourth pneumatic clamp, driven by the seventh driving mechanism, removes the assembled sensor from the clamping mechanism and sends it out, so that the clamping mechanism is restricted and waits for the next time to fix the shell again.

[0115] An optical sensor is also vertically arranged on the top of the base 1 , and the optical sensor is located below the rotating disk 4 . The optical sensor is used to sense whether there is a shell a in the clamping mechanism at the eighth position.

[0116] The present invention provides an assembly system for a current sensor. During assembly, first, multiple shells a are placed on a support tray 3 (the incoming materials are placed in the placement state), and the support tray 3 is located on a tray plate 2. Then, the first driving mechanism drives the first pneumatic clamp 6 to take out a shell a from the support tray 3, and put the shell a on the clamping mechanism at the first position (where the first position in this application is the position where the shell a is placed for the first time, and then the second position, the third position, and so on in counterclockwise rotation); before placing the shell a, the unlocking mechanism at the first position unlocks the clamping mechanism, and when the shell a is placed, the unlocking mechanism is moved away, so that the clamping mechanism fixes and clamps the shell a.

[0117] Afterwards, the motor drives the rotating disk 4 to rotate 45 degrees (45 degrees each time). At this position, the separation rod 7 is raised and inserted into the hole at the bottom of the shell a; then the separation rod 7 moves outward, driving the elastic arm f to separate from the shell a (most of the elastic arms f in the incoming material are in a separated state from the shell a, but some are fastened during transportation), until the separation rod 7 is separated from the shell a, the separation rod 7 is reset after it drops, and waits for the next action.

[0118] The rotating disk rotates again, and here a chip b is first engaged in the adsorption slot 9 at the end of the adsorption seat 8 (wherein during the engagement, the chip b can be sent to the adsorption slot 9 by a worker, or the chip b can be sent one by one to a position where the adsorption seat 8 can act on it by using a vibration disk, or there can be a visual picking robot under the adsorption seat 8, which has a pneumatic clamp. After each visual photo is taken, a chip b is taken out from the chip b disk and the pin d is clamped. Then the robot moves the pneumatic clamp to clamp the corresponding pin d, and moves the chip b shell to the adsorption seat 8, so that the chip b can be engaged in the adsorption slot 9; or it can be the combined action of the vibration disk and the robot, that is, the pneumatic clamp on the robot removes the chip b from the feeding track of the vibration disk and sends the chip b into the adsorption slot 9); after the chip b is engaged in the adsorption slot 9, the exhaust fan connected to the negative pressure hole 10 generates negative pressure, so that the chip b can not only be engaged in the adsorption slot 9, but also fit in the adsorption slot 9.

[0119] Then the third driving mechanism moves chip b, and makes chip b below and pin d above, and at the same time makes chip b be located above the hole above shell a; at this time, the negative pressure in negative pressure hole 10 disappears, but the position of adsorption seat 8 does not move, and the periphery of chip b is limited by shell a and adsorption slot 9, so the position of chip b can be temporarily maintained; then the pressing member 11 moves downward, pressing pin d downward, pressing chip b into the hole above shell a, and at the same time making the bent pin d able to be inserted into the slot at the top of shell a, and at the same time the slot and pin d have an interference fit.

[0120] After the rotating disk rotates again, the unlocking mechanism at the fourth position first unlocks the clamping mechanism, and then the fourth driving mechanism drives the second pneumatic clamp 12 to move, clamps the shell a, raises and rotates 180 degrees, and finally lowers it to the clamping mechanism, and the unlocking mechanism is released. At this time, the shell a is fixed on the clamping mechanism again, and the hole below is located above.

[0121] The rotating disk rotates again, and the third pneumatic clamp 14, under the driving action of the fifth driving mechanism, takes out a U-shaped magnetic core c with an opening facing downward from the magnetic support disk 13, and slightly inserts the bottom of the magnetic core c into the hole above the shell a (the third pneumatic clamp 14 clamps the top of the magnetic core c so that its bottom can be inserted into the shell a first); then the third pneumatic clamp 14 releases the magnetic core c, and the consolidation rod 15 presses downward to fully press the magnetic core c into the shell a.

[0122] The rotating disk rotates again, and the closing rod 16, under the driving action of the sixth driving mechanism, pushes the free end of the elastic arm f inward, and makes the elastic arm f and the shell a engage with each other, so that the protrusion g on the inner side of the elastic arm f can limit the outer side of the magnetic core c, and can fully limit the magnetic core c.

[0123] After the rotating disk rotates, the unlocking mechanism at the seventh position releases the clamping mechanism, and the fourth pneumatic clamp, under the driving action of the seventh driving mechanism, removes the assembled sensor from the clamping mechanism and sends it out, so that the clamping mechanism is restricted and waits for the next time to fix the shell a again.

[0124] First, the support tray 3 filled with shells a is arranged in multiple layers between the four full-plate arms 19 from top to bottom, and at the same time, the bottom sides of the bottom of the bottom support tray 3 are provided with two clamping parts 23, so that the position of the support tray 3 can be maintained; then during assembly, the second cylinder 30 lowers the height of the material tray plate 2, and the first guide seat 29 moves to the bottom of the full-plate arm 19, and then the second cylinder 30 raises the material tray plate 2, and makes the bottom of the bottom support tray 3 contact the material tray plate 2, and the periphery of the bottom support tray 3 all contact the limit block 25; then the first cylinder 21 drives the supporting plate and the clamping part 23 to move outward, the second cylinder 30 descends to a certain height, and the first cylinder 21 extends again, so that the clamping part 23 is inserted into the matching groove 24 of the bottom support tray 3, so that the clamping part 23 can support the bottom of the second to last support tray 3, and after the material tray plate 2 continues to descend, the bottom support tray 3 can be stably delivered by the material tray plate 2.

[0125] The first guide seat 29 moves to the loading position, the second guide seat 48 drives the fourth cylinder body 49 to move above the feeding plate, and then the fourth cylinder body 49 lowers the first rotating cylinder body 50, so that the first pneumatic clamp 6 can clamp a shell a, and then the fourth cylinder body 49 raises the first rotating cylinder body 50; after the raising, the driving linkage frame 51 and the second rotating cylinder body 52 of the first rotating cylinder body 50 rotate (the side wings e of the shell a placed on the support tray 3 are both facing downward, so it needs to be rotated horizontally 90 degrees); after the second guide seat 48 moves to a suitable position toward the rotating disk 4, the fourth cylinder body 49 lowers the first rotating cylinder body 50, and allows the shell a at this time to be placed on the clamping mechanism.

[0126] Before placement, the third cylinder 44 drives the unlocking member 45 to move toward the center of the rotating disk 4. At this time, the free end of the unlocking member 45 abuts against the end of the second unlocking portion 43, and the unlocking inclined surface 46 moves to abut against the first unlocking portion 42. In this way, the unlocking member 45 can simultaneously drive the first unlocking portion 42 and the second unlocking portion 43 to move, and the first clamping body 33 and the second clamping body 41 can not affect the normal placement of the shell a into the support groove 32; when the shell a is placed in the support groove 32, the unlocking member 45 moves backward. At this time, under the elastic force of the first elastic member 37 and the second elastic member 40, the first clamping body 33 and the second clamping body 41 are pressed and abutted against the adjacent two sides of the shell a. At the same time, the side of the shell a also abuts against the support seat 31, and one side wing e is stuck in a support groove 32, so that the position of the shell a is fully stable.

[0127] After the rotating disk 4 rotates 45 degrees, the fifth cylinder 53 raises the first slide cylinder 54, so that the top of the separation rod 7 passes through the make way slot 5 and is inserted into the hole at the bottom of the shell a. Then the first slide cylinder 54 drives the separation rod 7 to move outward, so that the free end of the elastic arm f can be driven outward and the elastic arm f can remain separated from the shell a.

[0128] After the rotating disk 4 rotates again, the third guide seat 56 moves outward, and the adsorption seat 8 is now located above the chip b to be taken. At this time, the second slide cylinder 57 drives the third slide cylinder 58 to move downward, and the adsorption seat 8 can engage a chip b (for example, there is a placement seat at the bottom of the adsorption seat 8, and the worker manually places a chip b on the placement seat each time for the adsorption seat 8 to take it); after the chip b is adsorbed, the second slide cylinder 57 raises the third slide cylinder 58, and the third guide seat 56 moves toward the top of the rotating disk 4; after reaching the specified position, the third rotating cylinder 59 rotates 90 degrees, so that the chip b is in a vertical state at this time, and the pin d is located above the chip b; then the second slide cylinder 57 drives the chip b downward, and makes The bottom of chip b is inserted into the hole at the top of shell a (after the adsorption seat 8 adsorbs chip b, the bottom of chip b is slightly lower than the bottom of the adsorption seat 8, so that the bottom of chip b can be inserted into the hole above shell a). After the negative pressure disappears, the sixth cylinder 60 drives the lower pressure piece 11 to move downward and act on the top of the pin d to press the chip b into the shell a; then the seventh cylinder 61 drives the lower pressure body 62 to move downward, further acting on the pin d, and fully presses the pin d into the shell a. Since the shape of the lower pressure body 62 matches the shape of the pin d, the pin d can be better prevented from deformation. In actual operation, the third slide cylinder 58 can compensate for the length of the second guide seat 48, so that the material picking range of chip b is wider.

[0129] The rotating disk 4 rotates again, and at this time the unlocking piece 45 unlocks the clamping mechanism at the fourth position, and then the fifth slide cylinder 64 drives the fourth rotating cylinder 65 to move inward, and makes the second pneumatic clamp 12 clamp the top and bottom of the shell a; then the fourth slide cylinder 63 rises, so that the shell a is separated from the clamping mechanism, and after the fourth rotating cylinder 65 rotates the shell a180 degrees, the fourth slide cylinder 63 lowers the shell a onto the support seat 31, and after the second pneumatic clamp 12 releases the shell a, the fifth slide cylinder 64 drives the second pneumatic clamp 12 outward to complete the flipping of the shell a.

[0130] The rotating shell a rotates again, and the fourth guide seat 67 moves outward, so that the acting part 71 is located above a magnetic core c, and then the sixth slide cylinder body 69 drives the third pneumatic clamp 14 downward. When the acting part 71 is located on both sides of the magnetic core c, after the acting part 71 clamps the magnetic core c, the sixth slide cylinder body 69 rises, and the fourth guide rail 66 moves toward the top of the rotating disk body 4 under the drive of the eighth cylinder body 68; after the magnetic core c reaches the top of the shell a, the sixth slide cylinder body 69 moves the magnetic core c downward, so that the bottom of the magnetic core c is inserted into the hole at the top of the shell a; then the acting part 71 releases the magnetic core c, and the ninth cylinder body 72 drives the consolidation rod 15 to press downward, fully pressing the magnetic core c into the shell a.

[0131] The rotating shell a rotates again, and the tenth cylinder 81 drives the closing rod 16 to move inward, and acts inward on the outer side of the free end of the elastic arm f, so that the elastic arm f is engaged with the shell a. The rotating shell a rotates again, and the unlocking member 45 here unlocks the clamping mechanism, and the eleventh cylinder drives the fourth pneumatic clamp downward and clamps the two sides of the shell a. Then the eleventh cylinder rises, and the seventh guide seat moves outward, so that the shell a is fit, and then the fourth pneumatic clamp releases the shell a and sends out the assembled product. The rotating disk 4 rotates again, and at the eighth position, the optical sensor senses from bottom to top whether there is a shell a on the clamping mechanism here. If not, assembly can continue. If so, the machine is stopped and manually checked or the shell a here is removed.

[0132] The shells a on the support tray 3 are arranged in rows. When the first pneumatic gripper 6 takes the shells a, the shells a in one row are first taken off, and then the first guide seat 29 continues to move the position of one row so that the shells a in the next row can be taken. When all the shells a are taken, the second cylinder 30 lowers the height of the tray plate 2 and moves to the bottom of the empty tray arm 20, and then lifts the support tray 3 with holes upward, and can directly lift up the empty support tray 3 at this time; during the lifting process of the new support tray 3, its two sides will act on the bottom of the inner side of the support inclined block 26 and drive the support inclined block 26 to move outward; after the support tray 3 passes over the support inclined block 26, the elastic body drives the support inclined block 26 to move outward, thereby supporting the support tray 3, so that the empty support trays 3 can be automatically stacked.

[0133] The magnetic cores c on the magnetic support disk 13 are also arranged in rows, wherein the magnetic cores c to be taken are located at the end of the magnetic cores c in the row. When the magnetic cores c at the end are taken, the optical sensor above or on the side senses that the magnetic cores c here are taken away, and then sends a signal to the controller. The controller controls the sixth guide seat 77 to move forward, and acts on the front end of the magnetic cores c in the row through the pusher 80, thereby pushing the entire column of magnetic cores c to move until it can sense that there are magnetic cores c at the end, and then the pusher 80 stops pushing, so that the magnetic cores c can be automatically taken one by one. When all the magnetic cores c in a row are taken, the fifth guide seat 74 moves one row toward the rotating disk 4, so that the next row of magnetic cores c can be taken. At the same time, since the sixth guide seat 77 is connected to the pusher 79 through the elastic buffer 78, when pushing the magnetic cores c, it can better prevent excessive pressure from being applied to the magnetic cores c, so that when the end magnetic core c is taken, it can not drive the penultimate magnetic core c. The elastic buffer member 78 preferably includes a guide rod and a spring, wherein there are two guide rods, and both are connected to the pusher 79, and the guide rod movably passes through the sixth guide seat 77; and the spring is movably sleeved on the outside of the guide rod, so that when pushing the magnetic core c, it mainly relies on the elastic force of the spring to push, thereby playing a buffering role.

[0134] The above description is only a description of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention. Any changes or modifications made by a person skilled in the art in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
