[0002] A new magnetic core is designed according to user needs. The structure of this magnetic core is composed of an upper magnet and a lower magnet sandwiched with a skeleton with a coil. The upper magnet and the lower magnet are fixed together by glue. The equipment currently used to assemble the magnetic core is in its early stages of development. The assembly of this magnetic core is carried out on a turntable, and the positions of various mechanisms are designed around the turntable. Therefore, this equipment is quite compact. Because of this, the equipment is too close to each other, which makes product changes very troublesome, or the product model cannot be changed. Utility Model Content

[0003] In order to solve the above problems, the utility model provides an in-line quick-change magnetic core machine, which solves the problem that product replacement is troublesome or impossible.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an in-line quick-change magnetic core machine, comprising a conveyor line, on which are provided a plurality of fixtures for clamping the lower magnetic core, characterized in that the conveyor line is an in-line conveying structure, and also comprises a magnetic core side column scraping mechanism and a magnetic core middle column glue dispensing mechanism arranged in sequence along the working direction of the conveyor line, the lower magnetic core passes through the magnetic core side column scraping mechanism and the magnetic core middle column glue dispensing mechanism in sequence, and the magnetic core side column scraping mechanism and the magnetic core middle column glue dispensing mechanism are used to sequentially apply glue to the side columns and the middle column of the lower magnetic core.

[0005] Furthermore, the conveyor line is a double-layer structure for feeding materials up, down, left and right, and the magnetic core is assembled on the upper layer of the conveyor line.

[0006] Furthermore, the conveyor line has a first track for the movable platform to move, and lifting devices located at both ends of the first track. The side of the lifting device is connected to a second track overlapping with the first track. The fixture moves from the first track to the second track, and the lifting device sends the fixture to another first track.

[0007] Furthermore, one end of the upper layer of the conveyor line is provided with a pushing cylinder, and the jig is pushed in one direction by the pushing cylinder.

[0008] Furthermore, it also includes a sliding mechanism, which is located below the lower layer of the conveyor line. The middle area of ​​the first track of the lower layer is an opening, and the jig is supported on both sides. The sliding mechanism is detachably connected to the jig through the opening, driving the jig to move on the first track.

[0009] Furthermore, the sliding mechanism pushes all the jigs on the first track.

[0010] Furthermore, the sliding mechanism includes a slide, a lifting cylinder, and a transverse moving mechanism. A plurality of positioning columns are provided on the surface of the slide, and the positioning columns correspond to the positioning holes on the bottom surface of the moving platform. A first slide rail is provided on the bottom surface of the slide. The piston rod of the lifting cylinder has a slider used in conjunction with the first slide rail. The lifting cylinder can lift the slide so that the positioning columns on the slide engage with the positioning holes. The transverse moving mechanism is connected to the slide. Therefore, all the fixtures in the lower layer are pushed together through the transverse moving mechanism. When the lifting cylinder lowers the slide, the positioning columns withdraw from the positioning holes, and the transverse moving mechanism drives the slide to reset.

[0011] Furthermore, the lateral movement mechanism includes a lateral movement cylinder, a connecting block, and a locking nut. A positioning groove is provided on the bottom surface of the slide. The connecting block is longitudinally arranged, and one end thereof is provided with a positioning convex strip used in conjunction with the positioning groove. The other end thereof has a notch extending from the end surface to the inside, and the notch extends to both sides of the one end. The piston rod of the lateral movement cylinder passes through the notch and is connected with a locking nut. When the lifting cylinder is lifted, the connecting block moves longitudinally. The design of the notch will not cause the connection with the lateral movement cylinder to be disconnected when the connecting block rises.

[0012] Furthermore, the core side column glue scraping mechanism includes a pulp disk, a pair of scrapers that reciprocate in the pulp disk, the pulp disk is filled with glue, the scrapers are arranged in the pulp disk in a side-by-side manner, and the glue is confined between the two scrapers. When the scrapers move back and forth, the glue moves in the pulp disk along with the scrapers. The bottom surface of the pulp disk is provided with a glue outlet corresponding to the top surface of the side column. When the scrapers reciprocate rapidly, the glue flows out from the glue outlet and covers the upper surface of the side column.

[0013] Furthermore, the scraper is fixed on the scraper cylinder, and the scraper is firmly pressed against the inner bottom surface of the pulp disc by the scraper cylinder, ensuring sufficient pressure to prevent glue from flowing out from between the scraper and the pulp disc.

[0014] Beneficial effects of the utility model:

[0015] The conveyor line adopts an in-line transportation method, which controls the moving direction of the fixture from a circular trajectory to up, down, left and right. The position relationship of the core side column scraping mechanism and the core middle column dispensing mechanism used in conjunction with it changes with the transportation direction, so that there is a gap between the mechanisms for debugging. Therefore, the problem of hindering product changeover is solved and the efficiency of changeover is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] See also Figure 15-16 As shown, it is a three-dimensional diagram of the product assembled by the utility model, and the product is an upper magnetic core 100, a coil 101, and a lower magnetic core 102, which are connected in sequence from top to bottom. The upper magnetic core 100 and the lower magnetic core 102 have the same structure, and both sides of the middle column 103 have zigzag side columns 104 extending outward. The zigzag design forms a mounting groove 105 between the side columns 104 and the middle column 103 to constrain the coil 101; the coil 101 is sleeved on the middle column 103 and sunk into the mounting groove 105, and the surfaces of the side columns 104 and the middle column 103 in the upper magnetic core 100 and the lower magnetic core 102 are coated with glue, and the two are fixed to each other by glue.

[0049] The utility model in-line quick-change magnetic core machine comprises a conveying line 2, a magnetic core side column scraping mechanism 3, and a magnetic core middle column dispensing mechanism 4. Figure 8 It can be seen that the conveyor line 2 is a double-layer structure for feeding materials up, down, left and right. There is a fixture 5 for positioning the magnetic core on the conveyor line 2. The right side above the conveyor line 2 is where the magnetic core has been assembled and is waiting to be taken out by other 5 mechanisms.

[0050] After taking out the magnetic core, the jig 5 moves from the right position of the upper layer 21 to the right position of the lower layer 22, then moves to the left position of the lower layer 22, and moves from the left position of the lower layer 22 to the left position of the upper layer 21, and keeps doing this cycle.

[0051] The assembly of the magnetic core is carried out on the upper layer 21 of the conveyor line 2, such as Figure 1-3 As shown, along the feeding direction of the conveyor line 2, the core side column glue scraping mechanism 3 and the core middle column glue dispensing mechanism 4 are sequentially arranged on the side of the conveyor line 2, and the assembly process is as follows: first, the lower magnetic core 102 is sent out from the fixture 5, and then the top surface of the side column 104 of the lower magnetic core 102 is scraped with glue, so that the surface of the side column 104 is adhered with glue, and then the core middle column glue dispensing mechanism 4 is used to scrape glue on the top surface of the middle column 103 of the lower magnetic core 102, and then the wire package 101 is put on, and the wire package 101 is placed in the installation groove 105 of the lower magnetic core 102, and then the upper magnetic core 100 is contacted with the lower magnetic core 102 correspondingly, and the glue is used to connect and fix each other.

[0052] like Figure 1-19 As shown, when the lower magnetic core 102 is scraping glue on the side column 104, the magnetic core side column glue mechanism 3 applies glue on the side column 104 in a scraping manner. The magnetic core side column glue scraping mechanism 3 includes a pulp disk 31, a pair of scrapers 32 that reciprocate in the pulp disk 31, the pulp disk 31 is filled with glue, and the scrapers 32 are arranged in the pulp disk 31 in a side-by-side manner, and the glue is constrained between the two scrapers 32. When the scrapers 32 make a reciprocating motion, the glue moves in the pulp disk 31 along with the scrapers 32. Therefore, the glue exists in the pulp disk 31 in the form of occupying a part of the longitudinal space; the bottom surface of the pulp disk 31 is provided with a glue outlet 33 corresponding to the upper top surface of the side column 104. When the scrapers 32 reciprocate quickly, the glue flows out from the glue outlet 33 and covers the upper surface of the side column 104;

[0053] Specifically, the scraper 32 is fixed on the scraper cylinder 34 , and the scraper cylinder 34 firmly presses the scraper 32 against the inner bottom surface of the pulp disk 31 , ensuring sufficient pressure to prevent glue from flowing out from between the scraper 32 and the pulp disk 31 .

[0054] The core center column glue dispensing mechanism 4 is a glue dispensing machine, which can move up and down and can be moved to the surface of the center column 103 to perform glue dispensing.

[0055] A calibration piece for positioning is also provided on the side of the conveyor line 2. The calibration piece is a pair of arms 61 opposite to each other. The arms 61 can be moved up and down. The space between the arms 61 constrains the wire package 101 to prevent the wire package 101 from being offset so as not to affect the installation of the upper magnetic core 100 and the lower magnetic core 102. The specific process is that the lower magnetic core 102 with the wire package 101 installed is moved to the bottom between the arms 61, and then the arms 61 are moved from top to bottom until the two arms 61 are located on both sides of the wire package 101, so that the wire package 101 cannot move horizontally to the left and right, thereby achieving the positioning effect of the wire package 101.

[0056] After installing the upper magnetic core 100, a pressing step is required to make the glue between the upper magnetic core 100 and the lower magnetic core 102 fully contact, and a magnetic core kneading mechanism 7 is also provided, the magnetic core kneading mechanism 7 includes a clamping cylinder 71 and a pressing block 72, the piston rod of the clamping cylinder 71 is connected to the pressing block 72, and the contact between the two is more closely fitted by longitudinal downward pressure and left-right movement of the driving motor;

[0057] In order to adjust the positional relationship between the pressure block 72 and the magnetic core, it also includes a driving motor 73, a mounting seat 74, and a slide plate 75. Second slide rails 76 are provided on the upper and lower sides of the mounting seat 74. The slide plate 75 is slidably connected to the second slide rails 76. The back side of the mounting seat 74 where the driving motor 73 is set has a motor shaft connected to a transmission mechanism. The transmission mechanism passes through the mounting seat 74 and is covered by an eccentric shaft 77. The eccentric shaft 77 is rotatably connected to one end of the connecting block 78, and the other end of the connecting block 78 is rotatably connected to the slide plate 75. Driven by the driving motor 73, the circular motion brought by the eccentric shaft 77 can make the slide plate 75 move left and right, and the clamping cylinder 71 installed on the slide plate 75 can be adjusted to the position above the magnetic core.

[0058] It should be noted that the fixture 5 has a clamping effect to prevent the magnetic core from detaching from the fixture 5. The fixture 5 includes a fixture body 51c, a moving table 51, a push rod 52, a push head 53, a guide rod 54, and a return spring 55. The fixture body 51c is installed on the moving table 51. The surface of the fixture body 51c has a pair of chucks, namely a fixed chuck 561 and a movable chuck 562. The position of the fixed chuck 561 cannot be changed, and the movable chuck 562 is movable. The fixture body 51c has a first end 51a close to the movable chuck 562. The surface of the fixture body 51c has an opening part adjacent to the first end 51a. The push rod 52 penetrates into the second end 51b and passes through the push head 53 in the opening part. The guide rod 54 is also located in the opening part and passes through the push head 53, the first end 51a, and the inside of the fixture body 51c. The return spring 55 is sleeved on the guide rod 54 for reset. A part of the structure of the push rod 52 is located outside the second end 51b. By pressing the push rod 52, the push head 53 fixedly connected to the push rod 52 will compress the return spring 55 along the direction of the guide rod 54. The movable chuck 562 is connected to the push head 53. The compression of the return spring 55 by the push head 53 will cause the movable chuck 562 to move away from the fixed chuck 561 and withdraw from clamping the magnetic core.

[0059] Based on the specific structure of the above-mentioned fixture 5, the conveying line 2 also has a positioning structure for positioning the fixture 5 and a stripping mechanism for pushing the push rod 52 to detach the magnetic core from the fixture 5. The conveying line 2 has a first track 57 for the moving table 51 to move. The positioning structure is a positioning rod 81 and a positioning cylinder 82 that penetrate through one side of the first track 57. The piston rod of the positioning cylinder 82 is connected to the positioning rod 81. A groove 59 is provided on the side surface of the moving table 51. When cooperating with the fixture 5 to strip the magnetic core, the positioning rod 81 penetrates into the knife positioning groove 59, making the fixture body 51c unable to move further. At this time, the stripping structure pushes the push rod 52 to make the fixture 5 release the clamping of the magnetic core.

[0060] Specifically, the shape of the groove 59 is a tip, and the push rod 52 is in the shape of "凵" and is fixedly engaged with the moving table 51 through the tips on both sides.

[0061] The stripping mechanism is a pressing block 83 controlled by a linear moving mechanism.

[0062] Both ends of the conveying line 2 are provided with a lifting device 23. The side surface of the lifting device 23 is connected with a second track 58 that coincides with the first track 57. The fixture 5 moves from the first track 57 on the upper layer 21 to the second track 58, and the lifting device 23 drives the fixture 5 into the lower layer 22 of the conveying line 2.

[0063] It should be noted that one end of the upper layer 21 of the conveyor line 2 is provided with a push cylinder 24, and the jig 5 is pushed in one direction by the push cylinder 24. The jig 5 of the lower layer 22 of the conveyor line 2 is moved as a whole by a sliding mechanism. The sliding mechanism is located below the lower layer 22 of the conveyor line 2. The middle area of ​​the first track 57 of the lower layer 22 is open, and the jig 5 is supported by both sides of the first track 57. The sliding mechanism includes a slide 91, a lifting cylinder 92, and a lateral moving mechanism. The surface of the slide 91 is provided with a plurality of positioning columns 93, and the positioning columns 93 and the moving table 51 are connected. The bottom surface of the slide 91 is provided with a first slide rail 95, and the piston rod of the lifting cylinder 92 has a slider 96 used in conjunction with the first slide rail 95. The lifting cylinder 92 can lift the slide 91, so that the positioning column 93 on the slide 91 is engaged with the positioning hole. The lateral moving mechanism is connected to the slide 91. Therefore, all the jigs 5 in the lower layer 22 are pushed together through the lateral moving mechanism; when the lifting cylinder 92 lowers the slide 91, the positioning column 93 withdraws from the positioning hole, and the lateral moving mechanism drives the slider 96 to reset, and this action is repeated over and over again.

[0064] The lateral movement mechanism includes a lateral movement cylinder 97 and a connecting block 98. A positioning groove 99 is provided on the bottom surface of the slide 91. The connecting block 98 is longitudinally arranged, and one end thereof is provided with a positioning ridge 65 used in conjunction with the positioning groove 99, and the other end has a notch 66 extending from the end surface to the inside, and the notch 66 extends to both sides of the one end. The piston rod of the lateral movement cylinder 97 passes through the notch 66 and is connected with a locking nut 67. When the lifting cylinder 92 is lifted, the connecting block 98 moves longitudinally. The design of the notch 66 will not cause the connection with the lateral movement cylinder 97 to be disconnected when the connecting block 98 rises.

[0065] The utility model includes multiple linear motion mechanisms for driving the above-mentioned mechanisms / devices / components. The linear motion mechanisms for up and down and left and right movement are prior arts. In order to ensure the neatness of the specification, they will not be described one by one. It is not that the specification lacks records of the up and down / left and right movement functions that can be achieved by each component, which constitutes insufficient disclosure.

[0066] In addition, it also includes a feeding mechanism for feeding the upper magnetic core 100, the coil 101, and the lower magnetic core 102. This is the existing technology and will not be described in detail.

[0067] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
