[0083] Please refer to Figures 1-9, in this embodiment, the automatic assembly line of the printer magnetic roller includes a handling mechanism 1, and further includes the following components arranged in sequence along the conveying direction of the handling mechanism 1:

[0084] The magnetic core feeding mechanism 2 is arranged at the feeding end of the handling mechanism;

[0085] The magnetic detection mechanism 3 includes a first material grabbing structure 31 and a testing structure 32. The first material grabbing structure 31 can place the magnetic core on the handling mechanism 1 onto the testing structure 32 and put the magnetic roller with qualified magnetism back onto the handling mechanism 1;

[0086] The sleeve assembling mechanism 4 includes a second material grabbing structure 41 and a clamping structure 42. The clamping structure 42 can clamp and fix the end of the magnetic core and make it hang above the handling mechanism 1. The second material grabbing structure 41 can grab the sleeve and coaxially sleeved it on the magnetic core;

[0087] The end cap assembling mechanism 5 includes a third material grabbing structure 51 and a glue dispensing structure 54. The third material grabbing structure 51 can place the end cap on the glue dispensing structure 54. The glue dispensing structure 54 can spray glue on the inner end of the end cap and coaxially sleeve the end cap on the magnetic core;

[0088] The glue overflow cleaning mechanism 6 includes a cleaning belt 61 and a driving structure 62. The driving structure 62 can make the magnetic roller roll relative to the cleaning belt 61 and generate rolling friction;

[0089] The laser diameter measuring mechanism 7 has a measuring structure 71 for measuring the diameter of the magnetic roller;

[0090] The magnetic roller discharging mechanism 8 is arranged at the discharging end of the handling mechanism 1.

[0091] In this embodiment, during production:

[0092] (1) Manual feeding: Place magnetic cores (first assemble the iron shaft and magnetic sheets) in the magnetic core feeding mechanism 2, place several sleeves in the sleeve assembling mechanism 4, and place several end caps in the end cap assembling mechanism 5;

[0093] (2) Automatic assembly: Use the handling mechanism 1 to drive the magnetic core to sequentially pass through the magnetic detection mechanism 3 (detect the magnetism of the magnetic sheet), the sleeve assembling mechanism 4 (sleeve the sleeve on the magnetic core), the end cap assembling mechanism 5 (sleeve the end cap on the end of the magnetic roller and dispense glue to achieve fixation), the glue overflow cleaning mechanism 6 (clean the glue overflowing between the end cap and the magnetic roller), the laser diameter measuring mechanism 7 (measure the diameter of the magnetic roller), and the magnetic roller discharging mechanism 8 (carry out material collection);

[0094] (3) Manual discharging or replenishing: Take the finished product from the material collection mechanism, or replenish sleeves in the sleeve assembling mechanism 4 and replenish end caps in the end cap assembling mechanism 5.

[0095] Preferably, the handling mechanism 1 includes:

[0096] A fixed frame 11, along the handling direction, is provided with several pairs of first lifting blocks 111 for placing magnetic rollers;

[0097] A movable frame 12, along the handling direction, is provided with several pairs of second lifting blocks 121 for placing magnetic rollers. The movable frame 12 can make the second lifting blocks 121 move back and forth vertically relative to the first lifting blocks 111 and move back and forth in the handling direction relative to the first lifting blocks 111.

[0098] In this embodiment, the handling mechanism 1 further includes a workbench and a power device 13, and several working mechanisms are arranged along the length direction of the workbench;

[0099] The fixed frame 11 includes a pair of first placing frames arranged oppositely and at the same height. Several first lifting blocks 111 are arranged along the length direction of the first placing frame. The top of the first lifting block 111 is provided with a V-shaped notch for placing the magnetic roller. Further, the first lifting block 111 is detachably connected to the first placing frame. By increasing or decreasing the opening angle of the V-shaped notch and the length of the first lift, it can adapt to magnetic rollers of different diameters;

[0100] The movable frame 12 includes a pair of second placing frames arranged oppositely and at the same height. A pair of second placing frames are respectively arranged inside a pair of first placing frames, so that when the magnetic roller is in a solid state (placed on the first lifting block 111) and in a transfer state (placed on the second lifting block 121), both ends of it are subjected to lifting forces, achieving the effect of force balance, thereby improving the smoothness of handling. Several second lifting blocks 121 are arranged along the length direction of the second placing frame. The structure of the second lifting block 121 is the same as that of the first lifting block 111, except that the height of the second lifting block 121 from the second placing frame is less than the height of the first lifting block 111 from the first placing frame, to avoid interference with the magnetic rollers placed on the first lifting blocks 111 when the movable frame 12 moves horizontally;

[0101] The power device 13 includes a motor 131, a driving wheel 132 drivingly connected to the output shaft of the motor 131, and a pair of follower cams 133. The pair of follower cams 133 are respectively arranged on both sides of the driving wheel 132. Rollers that are in rolling cooperation with the follower cams 133 on the same side are respectively arranged on the inner sides of the pair of second storage racks. When the driving wheel 132 rotates, it drives the follower cams 133 on both sides to rotate synchronously. By using the cooperation between the follower cams 133 and the rollers, the movable frame 12 can move relative to the fixed frame 11. Specifically, first, the workpiece / finished product located on the first lifting block 111 is separated from the fixed frame 11, then advances relative to the fixed frame 11 and is located above the next first lifting block 111, then descends relative to the fixed frame 11, and finally the second lifting block 121 resets, cycling in sequence; among them, the follower cam 133 can enable the second material placement rack to have four strokes. The first stroke is ascending (the workpiece is separated), the second stroke is advancing (the workpiece moves to the next working cavity), the third stroke is descending (the workpiece is placed on the next working cavity), and the fourth stroke is descending (resetting). Further, a track groove is formed on the side of the driving wheel 132, and the roller rolls along the track groove, which is beneficial to reducing the situation where the roller is separated from the follower cam 133, and improving the load of the movable frame 12 by using the structure of the double follower cams 133.

[0102] In this embodiment, the magnetic core feeding mechanism 2 includes a feeding workbench 21, a pair of feeding conveyor belts 22, and a plurality of third lifting blocks 23. The plurality of third lifting blocks 23 are arranged along the conveying direction of the feeding conveyor belt 22. A first notch for inserting the second material placement rack is formed at the discharging end of the pair of feeding conveyor belts 22. The second material placement rack takes the magnetic core located on the magnetic core feeding mechanism 2 by using the ascending stroke and the advancing stroke. Further, an alignment mechanism is provided between the magnetic core feeding mechanism 2 and the magnetic detection mechanism 3. The alignment mechanism includes a pair of push blocks, and the pair of push blocks can move inwards or outwards relative to the handling mechanism 1, so as to ensure that the magnetic core maintains a middle position on the first lifting block 111, reducing the position requirements for manually loading the magnetic core. As long as both ends of the magnetic core are respectively placed on the third lifting blocks 23; the working principle and structure of the magnetic roller discharging mechanism 8 in this embodiment are the same as those of the magnetic core feeding mechanism 2, and the difference lies in its function and conveying direction, which will not be elaborated here.

[0103] Preferably, the magnetic detection mechanism 3 further includes:

[0104] A first workbench 33, arranged on one side of the handling mechanism 1, and the testing structure 32 is arranged on the top of the first workbench 33;

[0105] A first information processing module, the first material grabbing structure 31 and the testing structure 32 are respectively electrically connected to the first information processing module;

[0106] The first material tray 34 is arranged on the first workbench 33 and is used for storing magnetic cores with substandard magnetism.

[0107] The first frame 35 straddles the first workbench 33 and the handling mechanism 1, and the first material-grabbing structure 31 is movably connected to the first frame 35.

[0108] In this embodiment, the conductive end of the iron shaft of the magnetic core is D-shaped. There is also a rotation alignment structure located below the first material-grabbing structure 31. The rotation alignment structure includes oppositely arranged bearing seats 73 and a liftable drive belt. When the drive belt descends and clings to the magnetic core, it drives the magnetic core to rotate self, making the D-shaped notch end of the conductive end of the magnetic core face downward and abut against the clamping platform on the bearing seat 73. When they abut, the magnetic core cannot rotate self, so when the first material-grabbing structure 31 grabs the magnetic core, it ensures that the D-shaped notch end faces downward.

[0109] The testing structure 32 includes a driving end 321 and a testing end 322. The driving end 321 can be adapted to the conductive end of the magnetic core and drive it to rotate self. Using the aforementioned rotation alignment structure, it is ensured that the drive can be fixed to the conductive end. By rotating, the magnetic core rotates relative to the testing end 322, thereby realizing the magnetic detection of the magnetic sheet. Finally, the test result is converted into an electrical signal and transmitted to the first information processing module. The first information processing module transmits an electrical signal to the first material-grabbing structure 31, puts the magnetic cores with qualified magnetism back into the handling mechanism 1, or places the magnetic cores with unqualified magnetism on the first material tray 34 for manual recycling and rework regularly.

[0110] The first material-grabbing structure 31 is a first robotic arm. A first sliding power device 13 is arranged on the first frame 35, which can drive the first robotic arm to slide between the first workbench 33 and the handling mechanism 1. The first robotic arm is provided with a first clamping part and a first lifting power component for controlling the lifting of the first clamping part.

[0111] Preferably, the sleeve assembly mechanism 4 further includes:

[0113] A second frame 44 straddles the sleeve bin 43 and the handling mechanism 1, and the second material-grabbing structure 41 is movably connected to the second frame 44.

[0114] The clamping structure 42 includes:

[0115] A second clamping part 422, which can fix or release the end of the magnetic core.

[0116] The second lifting seat 423, on which the second clamping part 422 is arranged, can drive the second clamping part 422 to approach or move away from the handling mechanism 1 in the vertical direction;

[0117] The second sliding seat 424, on which the second lifting seat 423 is arranged, can drive the second lifting seat 423 to approach or move away from the handling mechanism 1 in the horizontal direction.

[0118] In this embodiment, it further includes a plurality of second trays stacked in the vertical direction. The second trays are used to place the sleeves. The sleeve bin 43 includes an empty material area and a replenishment area that are stratified up and down. The empty material area is used to store the empty second trays, and the technician needs to place the second trays with sleeves on the replenishment area;

[0119] The second material grabbing structure 41 is a second robotic arm. A second sliding power device 13 is arranged on the second frame 44, which can drive the second robotic arm to slide between the sleeve bin 43 and the handling mechanism 1. The second robotic arm is provided with a second clamping part and a second lifting power component for controlling the lifting of the second clamping part; Further, a rotation alignment structure is arranged between the second frame 44 and the first frame 35, which is used to provide rotation alignment work for the magnetic cores discharged by the magnetic detection mechanism 3, facilitating the subsequent end cap sleeving process. The inner part of the conductive end cap is provided with an opening structure that is D-shaped adapted to the conductive end of the iron shaft. By using this rotation alignment structure, the situation where the conductive end cap cannot be installed is reduced. Furthermore, rotation alignment structures are arranged between adjacent operating mechanisms to keep the iron shafts in the same position, further improving the assembly accuracy;

[0120] A pair of second clamping claws are arranged on the second clamping part 422, and the opening and closing are realized through a thumb cylinder to fix or release the iron shaft. The second lifting seat 423 is used to separate the magnetic core to be sleeved from the first lifting block 111 on the fixed frame 11. The second robotic arm grabs the sleeve, starts from the end of the magnetic core far from the second clamping part 422, slides inward to sleeved the sleeve on the magnetic core, and finally uses the second lifting seat 423 to put the magnetic roller with the sleeve back on the first lifting block 111, thereby completing the assembly of the sleeve.

[0121] Preferably, the end cap assembly structure further includes:

[0122] The conductive cap bin 52;

[0123] The transmission cap bin 53, which is arranged on both sides of the handling mechanism 1 opposite to the conductive cap bin 52;

[0124] A pair of third racks 521 are respectively arranged on the conductive cover bin 52 and the transmission cover bin 53. There are a pair of the third material grabbing structures 51 and the dispensing structures 54. One of them is arranged on the conductive cover bin 52 and the other is arranged on the transmission cover bin 53. The third material grabbing structure 51 is movably connected to the third rack 521;

[0125] The dispensing structure 54 includes:

[0126] A dispensing needle valve 541 capable of spraying glue on the inner end of the end cover;

[0127] A third clamping part 542 capable of fixing or releasing the outer end of the end cover;

[0128] A third rotating seat 543. The third clamping part 542 is arranged on the third rotating seat 543 and can drive the third clamping part 542 to rotate relative to the dispensing needle valve 541;

[0129] A third sliding seat 544. The third rotating seat 543 is arranged on the third sliding seat 544 and can drive the third rotating seat 543 to approach or move away from the handling mechanism 1 in the horizontal direction.

[0130] In this embodiment, it further includes a number of third trays stacked in the vertical direction for placing conductive end covers, and a number of fourth trays stacked in the vertical direction for placing transmission end covers. The conductive cover bin 52 includes a third upper sliding table and a third lower sliding block that can move relative to each other. The third trays are placed on the third upper feeding table and the third lower feeding table, and the feeding state is switched by relative movement, so as to facilitate the technician to replenish the end covers. The structure and working principle of the transmission cover bin in this embodiment are the same as those of the conductive cover bin 52 and will not be elaborated here;

[0131] The third material gripping structure 51 is a third robotic arm. A third sliding power device 13 is provided on the third machine frame 521, which can drive the third robotic arm to slide between the conductive cover bin 52 and the dispensing mechanism. A third gripping part and a second lifting power component for controlling the lifting of the third gripping part are provided on the third robotic arm. The third robotic arm grips and places the conductive end cover on the third clamping part 542 of the dispensing mechanism. While the dispensing needle valve 541 is dispensing glue, the third rotating base 543 drives the third clamping part 542 to rotate, thereby driving the conductive end cover to rotate relative to the dispensing needle valve 541, and further achieving the purpose of uniform spraying. Finally, the third sliding seat 544 slides inward relative to the magnetic roller, pushing the conductive end cover to move inward and sleeving it on the conductive end of the magnetic roller. In this embodiment, dispensing structures 54 are respectively provided on the conductive cover bin 52 and the transmission cover bin 53, and their dispensing and assembly actions are carried out synchronously. The dispensing mechanism on the transmission end cover bin will not be elaborated here; further, in this embodiment, a clamping mechanism is also included, which is provided on the workbench of the handling mechanism 1 and includes a pair of rotatable L-shaped clamping arms. When the pair of third clamping parts 542 move inward, the pair of L-shaped clamping arms respectively flip upward and cooperate with the first lifting block 111 to fix the magnetic roller, avoiding the self-rotation of the magnetic roller relative to the first lifting block 111, which is beneficial to improving the accuracy of end cover assembly.

[0132] Preferably, this embodiment further includes:

[0133] An alignment and centering mechanism, which is provided between the sleeve assembly mechanism 4 and the end cover assembly mechanism 5, includes a pair of seventh sliding seats. The pair of seventh sliding seats are relatively arranged on both sides of the handling mechanism 1. One acts on the conductive end of the magnetic roller, and the other acts on the transmission end of the magnetic roller; an arc-shaped platform with a semi-open shape is provided on the seventh sliding seat. By using the pair of semi-open arc-shaped platforms to act on both ends of the magnetic roller simultaneously, the effect of adjusting the position of the magnetic roller in the horizontal direction is achieved, which is beneficial to avoiding the situation where the end cover is not assembled in place.
