[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner only, and therefore only show the components related to the present invention, and directions and references (e.g., up, down, left, right, etc.) may only be used to help describe the features in the drawings. Therefore, the following specific embodiments are not to be taken in a limiting sense, and the scope of the subject matter claimed is limited only by the attached claims and their equivalents.

[0018] like Figure 1-Figure 4 As shown, a multi-station chip dispensing assembly equipment includes a turntable 1, which is provided with at least a loading station 101, a dispensing station 102, an assembly station 103 and an unloading station 104 along the circumferential direction. A rotating drive mechanism 109 is arranged at the bottom of the turntable 1 for driving the turntable 1 to rotate. A fixed disk 11 is arranged at the center of the turntable 1. The fixed disk 11 is separated from the turntable 1 and supported by a support seat at the bottom.

[0019] The loading station 101 is used for loading magnetic cores; The glue dispensing station 102 is equipped with a glue dispensing mechanism 2 for dispensing glue on the upper surface of the magnetic core from the loading station 101. The glue dispensing mechanism 2 includes a glue dispensing valve 201 and a three-axis module 202 for driving the glue dispensing valve 201 to move in three-dimensional directions. There are multiple glue dispensing points. The assembly station 103 is equipped with an upper cover conveying component 3 for conveying the upper cover to the magnetic core after glue application to assemble the two. The magnetic core after glue application rotates with the turntable 1 to the assembly station 103, and the upper cover conveying component 3 transfers the upper cover on it to the magnetic core, and the magnetic core and the upper cover are glued; Each workstation is provided with a locking mechanism 4 for locking the magnetic core thereon, which includes a base 401 for supporting the magnetic core, a clamp 402 hingedly connected to the base 401, and an elastic element 403 for pushing the clamp 402 to clamp the magnetic core between the clamp 402 and the base 401. The clamp 402 can rotate around the hinge point between it and the base 401 to form a scissors-like structure, and the magnetic core and the elastic element 403 are respectively located on both sides of the hinge point. The elastic element 403 can be a spring, the base 401 protrudes to form a first protrusion, the clamping plate 402 protrudes to form a second protrusion, the elastic element 403 is sleeved on the first protrusion and the second protrusion, and one end of the elastic element 403 abuts against the base 401, and the other end abuts against the clamping plate 402; the base 401 is provided with a groove for inserting the magnetic core, the clamping plate 402 is located on one side of the groove, and a stopper 406 is fixed on the other side of the groove, and a clamping cavity 405 for clamping the magnetic core is formed between the clamping plate 402 and the stopper.

[0020] The loading station 101 and the unloading station 104 are also provided with a pressure mechanism 404 for applying pressure to the clamp 402 so that it overcomes the force of the elastic element 403 and releases the clamping of the magnetic core. The pressure mechanism 404 can be but is not limited to a cylinder or a telescopic rod, etc., which is installed on the base 407 and the position is adjustable. A waist-shaped hole is provided on the pressure mechanism 404 or the base 407. The waist-shaped hole can be a straight bar or an arc to allow the pressure mechanism 404 to be moved horizontally or rotated.

[0021] During the process of receiving the magnetic core, the pressure mechanism 404 of the loading station 101 first applies pressure to the clamping plate 402, so that the clamping plate 402 overcomes the force of the elastic element 403 and opens the clamping cavity 405. After the magnetic core is placed in the clamping cavity 405, the pressure mechanism 404 releases the pressure on the clamping plate 402, and the clamping plate 402 locks the magnetic core under the elastic force of the elastic element 403. Then the turntable 1 drives the magnetic core to rotate to the glue dispensing station 102, and the glue dispensing mechanism 2 dispenses glue on its upper surface. Then the turntable 1 drives the magnetic core to rotate to the assembly station 103, and at the same time the upper cover conveying component 3 conveys the upper cover to the magnetic core and glues it to form a semi-assembly. Finally, the turntable 1 drives the semi-assembly of the magnetic core and the upper cover to rotate to the unloading station 104 for unloading.

[0022] The present invention utilizes a turntable to transfer the magnetic core between various workstations to complete the assembly. The transfer route is circular, and various supporting mechanisms are correspondingly arranged at each workstation. The overall layout is compact, and each workstation automatically locks the magnetic core thereon through a locking mechanism to ensure the position accuracy of the magnetic core during the transfer process, thereby improving the overall assembly accuracy of the chip, and the magnetic core is automatically unlocked by a pressure mechanism at the loading and unloading stations, thereby realizing automatic loading and unloading and assembly of the magnetic core and the upper cover. The entire equipment is fully automatically operated, and the repeated assembly accuracy of the magnetic core and the upper cover can reach μ level.

[0023] In some examples, such as Fig.12 and Fig.13 As shown, it also includes a magnetic core feeding assembly 5 for feeding materials to the loading station 101, a first correction mechanism 6 arranged on the feeding path of the magnetic core feeding assembly 5 and used for centering the conveyed magnetic cores, and a second correction mechanism 7 arranged on the unloading path and used for centering the magnetic cores and the upper cover; The position of the magnetic core itself may have deviations when it is transported through the magnetic core conveyor line 506. If it is directly transported to the turntable 1 for assembly with the upper cover, the assembly accuracy will be reduced. Therefore, a first correction mechanism 6 is set on the feeding path to correct the deviation and improve the assembly accuracy.

[0024] After the magnetic core passes through the first correction mechanism 6, it has a higher position accuracy, while the position of the upper cover itself will deviate during its transportation process. When it is transported to the assembly station 103 for assembly with the magnetic core, it will still lead to reduced assembly accuracy. Therefore, the position of the upper cover needs to be corrected. Because it is assembled with the magnetic core by gluing, the position can be fine-tuned before the glue solidifies. Therefore, a second correction mechanism 7 can be set on the unloading path to correct the position deviation of the upper cover and control the assembly accuracy.

[0025] In some examples, such as Figure 14-18 As shown, the first correction mechanism 6 and the second correction mechanism 7 both include a jig 601 for carrying a magnetic core, a flexible four-claw structure 602 that can be moved closer to or farther away from each other, and a buffer elastic member correspondingly arranged between a clamp 6021 of the flexible four-claw structure 602 and the jig 601. The buffer elastic member corresponds to the clamp 6021 one by one, and the elastic coefficients of the buffer elastic member between the two relatively arranged clamps 6021 and the jig 601 are different, namely, a first buffer elastic member 603 and a second buffer elastic member 604, and the elastic coefficient of the first buffer elastic member 603 is greater than the elastic coefficient of the second buffer elastic member 604. The larger the elastic coefficient, the greater the elastic force, and the less likely it is to deform. The buffer elastic member can be a spring, the first buffer elastic member 603 with a large elastic coefficient is a "hard" spring, and the second buffer elastic member 604 with a small elastic coefficient is a "soft" spring; the elastic coefficient is related to the wire diameter, outer diameter and material of the spring.

[0026] Both ends of the buffer elastic member are respectively hooked with the connecting shaft 608 fixed on the clamp 6021 and the fixture 601, and the connecting shaft 608 fixed on the clamp 6021 and the connecting shaft 608 fixed on the fixture 601 are perpendicular to each other. The connecting shaft 608 can be but is not limited to a pin shaft or a bolt.

[0027] Each clamping jaw 6021 is adjustable and equipped with a non-magnetic clamp 609 for clamping the magnetic core or the upper cover. The clamp is made of non-magnetic material to prevent the magnetic material from damaging the internal structure of the magnetic core. The clamp 609 on the flexible four-claw structure 602 in the first correction mechanism 6 is used to clamp the magnetic core, and the clamp 609 on the flexible four-claw structure 602 in the second correction mechanism 7 is used to clamp the magnetic core and the upper cover, two of which are used to clamp the magnetic core, and the other two clamps 609 are used to clamp the upper cover.

[0028] Taking the first correction mechanism 6 as an example, the grasping mechanism first grasps the magnetic core from the magnetic core conveying line 506 to the fixture 601, and then the flexible four-claw structure 602 moves closer to each other to clamp and position the magnetic core. During the clamping process, the high-rigidity first buffer elastic member 603 is not easy to deform and has a large elastic force. It allows the displacement change of the clamp 6021 connected to it to be small, and when the first buffer elastic member 603 undergoes a unit deformation, the force applied to the magnetic core by the clamp 6021 connected to it is large. The low-rigidity second buffer elastic member 604 is easy to deform and has a small elastic force. It allows the displacement change of the clamp 6021 connected to it to be large, and when the second buffer elastic member 604 undergoes a unit deformation, the force applied to the magnetic core by the clamp 6021 connected to it is small. In this way, the combined force can be achieved, while ensuring the centering effect of the magnetic core, avoiding damage to the magnetic core.

[0029] In some examples, such as Fig.15 and Fig.16 As shown, the jig 601 is provided with a positioning groove 6011 for placing the magnetic core for initial positioning thereof and a negative pressure channel 6012 connected with the positioning groove 6011 for adsorbing the magnetic core. The negative pressure channel 6012 is connected with a negative pressure device. When the negative pressure device is turned on, the negative pressure channel 6012 is in a negative pressure state, thereby adsorbing and fixing the magnetic core in the positioning groove 6011 to prevent the small-volume magnetic core from flipping over or detaching from the positioning groove 6011 under the clamping force of the flexible four-claw structure 602.

[0030] In some examples, such as Fig.14 As shown, the first correction mechanism 6 and the second correction mechanism 7 also include a swing table 605 for driving the fixture 601 to rotate, a first slide 606 for driving the fixture 601 to move along a first direction, and a second slide 607 for moving along a second direction perpendicular to the first direction. The swing table 605, the second slide 607 and the first slide 606 are stacked in sequence from top to bottom. The first slide 606 and the second slide 607 both include a fixed seat 6061, a sliding seat 6063 and a screw nut structure 6062 located therebetween. The sliding seat 6063 is covered on top of the fixed seat 6061, and the sliding seat 6063 of the first slide 606 is fixed to the fixed seat 6061 of the second slide 607.

[0031] In some examples, such as Figure 7-Figure 9As shown, the base 401 includes a bottom plate 4011 and a cover plate 4012 fixed above the bottom plate 4011, and the two are enclosed to form a through slot 4013 for the clamping plate 402 to pass through, and the slot width of the through slot 4013 is greater than the width of the clamping plate 402 so that the clamping plate 402 can rotate within a certain range to clamp or release the magnetic core, and the bottom plate 4011 protrudes to form a limiting protrusion 4014 for limiting the rotation range of the clamping plate 402, and the limiting protrusion 4014 can be integrally formed with the base 401 or be a pin fixed on the base 401.

[0032] In some examples, such as Fig.12 and Fig.13 As shown, the magnetic core feeding assembly 5 includes a magnetic core manipulator 501 that can move in three-dimensional directions. Two synchronously acting magnetic core suction nozzles 502 are installed on the magnetic core manipulator 501. Each magnetic core suction nozzle 502 is installed on the magnetic core manipulator 501 through a first floating seat 503. A first floating spring 504 and a first guide mechanism 505 are provided between the first floating seat 503 and the magnetic core manipulator 501. The first floating spring 504 is used to provide a buffering effect on the magnetic core during the process of the magnetic core suction nozzle 502 sucking the magnetic core, thereby avoiding damage to the magnetic core during the suction process. The first guide mechanism 505 can be a slide rail and slider combination to ensure the movement direction of the magnetic core suction nozzle 502 during the buffering process.

[0033] One of the magnetic core suction nozzles 502 (first magnetic core suction nozzle) is used to convey the magnetic core on the magnetic core conveying line 506 to the first correction mechanism 6, and the other magnetic core suction nozzle 502 (second magnetic core suction nozzle) is used to convey the magnetic core on the first correction mechanism 6 to the loading station 101, and when the first magnetic core suction nozzle sucks the magnetic core on the magnetic core conveying line 506 and drives it to move horizontally, the second magnetic core suction nozzle sucks the magnetic core that has been corrected on the first correction mechanism 6 and drives it to move horizontally. At this time, the station on the first correction mechanism 6 is vacant for the magnetic core to be corrected to be placed. When the first magnetic core suction nozzle drives the magnetic core to be corrected thereon to reach the first correction mechanism 6, the second magnetic core suction nozzle drives the magnetic core thereon to reach the loading station 101, and then the first magnetic core suction nozzle and the second magnetic core suction nozzle are reset for a new round of suction. One end of the magnetic core manipulator 501 is supported by the supporting structure at its bottom, and the other end is supported by the fixed disk 11, which improves the structural stability while saving space.

[0034] In some examples, such as Fig.10As shown, the upper cover conveying assembly 3 includes a vibrating material tray 301 and an upper cover manipulator 302 which can move in three-dimensional directions and is used to transfer the upper cover at the output port of the vibrating material tray 301 to the assembly station 103. The upper cover manipulator 302 is equipped with an upper cover suction nozzle 303 through a second floating seat 304. A second floating spring 305 and a second guide mechanism 306 are provided between the second floating seat 304 and the upper cover manipulator 302. The second floating spring 305 is used to provide a buffering effect when the upper cover suction nozzle 303 sucks the upper cover to the assembly station 103 for assembly. The second guide mechanism 306 can be a combination of slide rails and sliders to ensure the movement direction of the upper cover suction nozzle 303 during the buffering process. One end of the upper cover manipulator 302 is supported by the supporting structure at its bottom, and the other end is supported by the fixed plate 11, which improves the structural stability while saving space.

[0035] In some examples, such as Fig.19 and Fig. 20 As shown, a material unloading manipulator 8 that can move in three-dimensional directions is provided between the unloading station 104 and the second correction mechanism 7. The material unloading manipulator 8 is to clamp the semi-assembly of the magnetic core and the upper cover. At this time, the glue between the two is not solidified, so the suction method cannot be used but the clamping method is required. Therefore, the finger 801 of the material unloading manipulator 8 includes a magnetic core clamping part 8011 and an upper cover clamping part 8012 recessed in the magnetic core clamping part 8011. One end of the material unloading manipulator 8 is supported by the support structure at its bottom, and the other end is supported by the fixed plate 11, which improves the structural stability and saves space.

[0036] The finger 801 is installed on the unloading robot 8 through the third floating seat 802. A third floating spring 803 is provided between the third floating seat 802 and the upper cover robot 302. The third floating spring 803 is used to provide a buffering effect when the finger 801 clamps the magnetic core and the upper cover.

[0037] In some examples, such as Figure 5 and Figure 6 As shown, a magnetic core detection station 105 is provided between the loading station 101 and the glue dispensing station 102, and the magnetic core detection station 105 is equipped with a magnetic core visual detection mechanism 9, and the magnetic core visual detection mechanism 9 is used to locate the magnetic core position, and a glue dispensing detection station 106 is provided between the glue dispensing station 102 and the assembly station 103, and the glue dispensing detection station 106 is equipped with a glue dispensing visual detection mechanism 10, and the glue dispensing visual detection mechanism 10 is used to detect whether glue is dispensed and locate the glue dispensing position, preferably, a reserved station 107 is provided between the assembly station 103 and the unloading station 104, and a residual material detection station 108 is provided between the unloading station 104 and the loading station 101, and the residual material detection station 108 is equipped with a residual material visual detection mechanism, which is used to detect whether the unloading is missed, so as to avoid interference with the magnetic core to be loaded when rotating to the loading station 101.

[0038] Working principle: 1. Feeding: First, the first magnetic core suction nozzle on the magnetic core manipulator 501 conveys the magnetic core on the magnetic core conveying line 506 to the first correction mechanism 6, and at the same time, the second magnetic core suction nozzle is used to convey the corrected magnetic core on the first correction mechanism 6 to the loading station 101, and then the first magnetic core suction nozzle and the second magnetic core suction nozzle are reset to start a new round of suction; 2. Magnetic core centering: The magnetic core manipulator 501 absorbs the magnetic core on the magnetic core conveying line 506 into the positioning groove 6011 of the first correction mechanism 6 for initial positioning, and then the flexible four-claw structure 602 moves closer to each other to clamp and position the magnetic core. During the clamping process, the first buffer elastic member 603 with high rigidity is not easy to deform and has a large elastic force, while the second buffer elastic member 604 with low rigidity is easy to deform and has a small elastic force, thereby achieving a comprehensive force, ensuring the magnetic core centering effect while avoiding damage to the chip; 3. Magnetic core position detection: the turntable 1 drives the magnetic core to rotate to the magnetic core detection station 105, and the magnetic core visual detection mechanism 9 locates the magnetic core position; 4. Glue dispensing: the turntable 1 drives the magnetic core to rotate to the glue dispensing station 102, and the glue dispensing mechanism 2 performs glue dispensing; 5. Glue dispensing inspection: The turntable 1 drives the magnetic core to rotate to the glue dispensing inspection station 106, and the glue dispensing visual inspection mechanism 10 detects whether the magnetic core has glue dispensing and locates the glue dispensing position; 6. Assembly: The turntable 1 drives the magnetic core to rotate to the assembly station 103, and the upper cover suction nozzle 303 of the upper cover manipulator 302 sucks the upper cover to the assembly station 103 and puts it on the magnetic core to make the two stick together; 7. Unloading: The turntable 1 drives the semi-assembly formed by the magnetic core and the upper cover to rotate to the unloading station 104; 8. Semi-assembly centering: The unloading robot 8 grabs the semi-assembly of the magnetic core and the upper cover into the positioning groove 6011 of the second correction mechanism 7 for initial positioning, and then the flexible four-claw structure 602 moves closer to each other to clamp and position the magnetic core. During the clamping process, the buffer elastic parts with different elastic coefficients provide different degrees of buffering to the clamping claws 6021, ensuring the centering effect of the magnetic core while avoiding damage to the magnetic core; 9. Curing: After the secondary correction is completed, the handling module moves the semi-assembly to the oven for heating and curing of the finished product.
