[0065] 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, 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.

[0066] like Figure 1-Figure 3As shown, a chip dispensing and curing automatic flow production line, the chip includes a magnetic core and an upper cover arranged on the upper cover, the production line is used to cure the glue between the magnetic core and the upper cover to fix the two, the production line is a ring structure, including a curing line and a reflow line;

[0067] The curing line includes a combined preheating zone 1, a high-temperature curing zone 2 and a heat preservation zone 3 which are arranged in sequence. The three are arranged in a straight line and are all equipped with a heating mechanism for heating them. The heating mechanism can be but is not limited to a heating rod, etc. A cover is provided on the high-temperature curing zone 2 to maintain its high-temperature environment.

[0068] The combined preheating zone 1 includes a chip entrance 1a, a fixture entrance 1b and a first pushing mechanism 4 for pushing the fixture 16 and the chip thereon into the high temperature curing zone 2 and the heat preservation zone 3 in sequence. Each fixture 16 is provided with a plurality of receiving grooves 1606 for accommodating the chip to position the chip. The chip corresponds to the receiving groove 1606 one by one. The combined preheating zone 1 is also provided with a visual detection mechanism for detecting whether the fixture 16 thereon is tilted.

[0069] After the jig 16 enters the combined preheating zone 1 from the jig entrance 1b, the loading robot 17 places the chip on the jig 16 through the chip entrance 1a to form an assembly. Multiple assemblies are arranged in a straight line. The first pushing mechanism 4 located at the front end of the combined preheating zone 1 applies pressure to the assembly adjacent to it. Multiple assemblies interact with each other and then enter the high-temperature curing zone 2 and the insulation zone 3 in turn. The temperature of the combined preheating zone 1 is lower than that of the high-temperature curing zone 2. It is used to preliminarily heat the jig 16 and the chip thereon. On the one hand, it can allow the glue to have a certain temperature basis before entering the high-temperature curing zone 2 for curing, thereby improving the curing efficiency. On the other hand, it can avoid the assembly directly entering the high-temperature curing zone 2, which causes the temperature to rise too quickly, thereby affecting the curing effect of the glue and causing damage to the chip.

[0070] The insulation zone 3 is provided with a chip outlet 3a, a fixture outlet 3b and a material taking robot 5 for sucking the chip to separate the chip from the fixture 16; the temperature of the insulation zone 3 is lower than the temperature of the high-temperature curing zone 2, and it is used to keep the fixture 16 and the chip thereon warm, so as to avoid a rapid drop in temperature of the chip after it comes out of the high-temperature curing zone 2.

[0071] A pressure component is provided on the pushing path of the first pushing mechanism 4, which is used to lock the chip above the jig 16 when the chip enters the high-temperature curing zone 2 to continuously apply pressure to the chip between the two, thereby preventing the upper cover from shifting and allowing the high-temperature curing process to proceed under a certain pressure to improve the curing effect. After entering the insulation zone 3, it automatically separates from the jig 16 and rotates back to the entrance of the high-temperature curing zone 2 to apply pressure to the chips on the next round of jigs 16.

[0072] The reflux line is used to rotate and transport the jig 16 from the jig outlet 3b to the jig inlet 1b, and a residual material cleaning area 6 for removing residual chips on the jig 16 and a jig preheating area 7 for preheating the jig 16 are provided on its transport path; during the rotation of the jig 16, the jig preheating area 7 first heats the jig 16, and the heated jig 16 enters the combined preheating area 1 and is further heated together with the chips thereon.

[0073] First, the jig 16 automatically enters the combined preheating zone 1 through the jig entrance 1b, and the loading robot 17 grabs the chip into the receiving slot 1606 of the jig 16. After the current jig 16 is full of chips, the first pushing mechanism 4 pushes the current jig 16 to move in the direction of the high-temperature curing zone 2. The jigs 16 interact with each other and move synchronously. They are preheated synchronously in the process of waiting for loading and in the process of the chip and the jig 16 moving to the high-temperature curing zone 2 after loading. When it is about to enter the high-temperature curing zone 2, the pressure component is pressed on the top of the chip and continues to press it during the entire process of high-temperature curing. After leaving the high-temperature curing zone 2, the pressure component automatically separates from the chip and rotates to the entrance of the high-temperature curing zone 2 to press the chips on the next round of jigs 16. Then the jig 16 and the chips on it move to the end of the insulation zone 3, and the material taking robot 5 takes the chip away from the chip outlet 3a. After the residual material is removed and the initial temperature is raised, the jig 16 enters the combined preheating zone 1 again and repeats the above operations to form a complete automated curing production line, thereby improving the curing efficiency.

[0074] In some examples, such as Figure 11-15 As shown, the pressure applying component includes:

[0075] The pressure-applying body 8 comprises a base 801 covering the chip, a pressure rod 802 slidably arranged in the base 801 and extending toward the chip to apply pressure to the chip, a first elastic member 803 for applying pressure to the pressure rod 802, a locking hook 804 hingedly arranged on the base 801, and a second elastic member 805 for applying pressure to the locking hook 804 so that the locking hook 804 is hooked with the fixture 16, and the fixture 16 protrudes toward the base 801 to form a positioning protrusion 1605, and the positioning protrusion 1605 can be a pin shaft, and a positioning groove for inserting the positioning protrusion 1605 to preliminarily position the two is opened on the base 801;

[0076] There are multiple pressing rods 802 and first elastic members 803, which correspond to multiple chips one by one. Each pressing rod 802 is used to press the corresponding chip so that the glue between the magnetic core and the upper cover is solidified under a certain pressure.

[0077] and a transport body 9, comprising a clamping jaw 901 for clamping a base 801 to transport it, a base 902 for mounting the clamping jaw 901, a transverse driving mechanism 903 for driving the two clamping jaws 901 to move closer to or away from each other, a longitudinal driving mechanism 904 for driving the clamping jaws 901 to move up and down, and a transporting mechanism 905 for driving the base 902 to move closer to or away from the pressure-applying body 8, wherein the clamping jaw 901 applies pressure to the locking hook 804 while clamping so that the locking hook 804 overcomes the force of the second elastic member 805 and is separated from the fixture 16;

[0078] First, the clamping jaw 901 moves the clamped pressure-applying body 8 to the top of the jig 16 at the entrance of the high-temperature curing zone 2. First, the pressure-applying body 8 and the jig 16 are initially positioned by inserting the positioning protrusion 1605 into the positioning groove. Then, the clamping jaw 901 releases the pressure-applying body 8. The second elastic member 805 resets and drives the locking hook 804 to rotate to hook the jig 16, locking the pressure-applying body 8 and the jig 16 to form a combined structure. The pressure rod 802 presses the chip under the elastic force of the first elastic member 803. Then, the combined structure formed by the jig 16 and the pressure-applying body 8 pressed thereon enters the high-temperature curing zone 2 under the push of the first pushing mechanism 4. The glue solidifies to fix the magnetic core and the upper cover. After the curing is completed The combined structure enters the insulation zone 3, and the clamping jaws 901 move to the top of the combined structure. When the clamping jaws 901 clamp the pressure-applying body 8, the clamping jaws 901 push the locking hook 804, so that the locking hook 804 overcomes the resistance of the second elastic member 805 and rotates to separate from the jig 16. At the same time, the clamping jaws 901 transport the clamped pressure-applying body 8 to the entrance of the high-temperature curing zone 2 for the next round of pressure. In this embodiment, when the conveying body 9 conveys the pressure-applying body 8 to the top of the jig 16, the clamping jaws 901 are automatically locked with the jig 16 while being released, and when the conveying body 9 conveys the pressure-applying body 8, the clamping jaws 901 are automatically unlocked with the jig 16 while clamping, thereby realizing automatic locking and unlocking.

[0079] In some examples, such as Figure 7 and Figure 8 As shown, the return line also includes:

[0080] The second pushing mechanism 10 is used to push the jig 16 from the autonomous jig outlet 3b into the residual material cleaning area 6, and its movement path is perpendicular to the pushing path of the first pushing mechanism 4;

[0081] The fixture manipulator 11 is used to transport the fixture 16 from the residual material cleaning area 6 to the fixture preheating area 7, and its movement path is parallel to the pushing path of the first pushing mechanism 4. Fig.17 As shown;

[0082] The third pushing mechanism 12 is used to push the jig 16 from the future jig preheating zone 7 to the jig entrance 1b, and its movement path is perpendicular to the pushing path of the first pushing mechanism 4;

[0083] And the fourth pushing mechanism 13 is located between the fixture robot 11 and the third pushing mechanism 12, and is used to push the fixture 16 of the future autonomous fixture robot 11 to the third pushing mechanism 12 in sequence, and its movement path is parallel to the pushing path of the first pushing mechanism 4.

[0084] In some examples, the residual material cleaning area 7 is provided with a purge assembly 14 for blowing chips remaining on the jig 16 off the jig 16 and a collection box 15 for receiving the blown-off chips. The collection box 15 is located on the blowing path of the purge assembly 14 and the side of the collection box 15 facing away from the purge assembly 14 is raised to form a blocking portion to prevent the chips from being blown out of the collection box 15.

[0085] In some examples, the outer peripheral wall of the jig 16 is recessed to form a locking groove 1601, one end of the locking hook 804 is a hook portion 8041 embedded in the locking groove 1601, and the other end is a clamped portion 8042 for clamping by the clamping claw 901, the hook portion 8041 can be rotated to be embedded in the locking groove 1601 under the elastic force of the second elastic member 805 to achieve the locking of the base 801 and the jig 16, and rotated out of the locking groove 1601 under the action of the clamping claw 901 to achieve the unlocking of the base 801 and the jig 16, and the base 801 is provided with a limiting groove 8013 for accommodating the locking hook 804 and limiting its rotation range;

[0086] The clamping jaw 901 includes a supporting portion 9011 for supporting the base 801 and a clamping portion 9012 for clamping the clamped portion 8042, and the base 801 has a supporting step 8011 for cooperating with the supporting portion 9011, and the clamped portion 8042 of the locking hook 804 extends upward from a limiting groove 8013 to cooperate with the clamping portion 9012. When the clamping jaw 901 is carried, the supporting portion 9011 cooperates with the supporting step 8011 to support the pressure-applying body 8, and at the same time the clamping portion 9012 clamps the pressed portion to allow the locking hook 804 to rotate.

[0087] In some examples, a slide groove 8012 is formed in the base 801 for the pressure rod 802 to slide, and an elastic force adjustment block 806 is provided at one end of the slide groove 8012 away from the chip, the pressure rod 802 protrudes in the direction of the elastic force adjustment block 806 to form a guide portion, the first elastic member 803 is sleeved on the guide portion, and one end of the first elastic member 803 abuts against the pressure rod 802, and the other end abuts against the elastic force adjustment block 806. By adjusting the position of the elastic force adjustment block 806, the compression amount of the first elastic member 803 can be adjusted, thereby adjusting the pressure exerted on the pressure rod 802, and the elastic force adjustment block 806 is knocked into the slide groove 8012 and has an interference fit with the slide groove 8012;

[0088] A pressure block matching the shape of the chip is fixed at the bottom of the pressure rod 802 to avoid chip tilting due to uneven pressure, and the pressure block can abut against the lower surface of the base 801 to limit the pressure rod 802 from retracting into the slide groove 8012. The pressure rod 802 has a radially protruding protrusion for limiting its sliding out of the slide groove 8012. The pressure block cooperates with the protrusion to limit the movement range of the pressure rod 802.

[0089] In some examples, such as Fig. 9 and Fig.10 As shown, the combined preheating zone 1 , the high temperature curing zone 2 and the insulation zone 3 are each provided with a partition 18 between adjacent ones to prevent the high temperature of the high temperature curing zone 2 from being directly transferred to the combined preheating zone 1 and the insulation zone 3 .

[0090] In some examples, such as Figure 4-Figure 6 As shown, the material picking robot 5 includes a material picking base block 501 and a plurality of suction nozzles 502 slidably arranged in the material picking base block 501 and extending toward the chip direction. Each suction nozzle 502 is located above the material picking base block 501 and is protruded to form an upper limit portion 503, and is located below The part protrudes to form a lower limit portion 504, the upper limit portion 503 and the lower limit portion 504 can limit the movement stroke of the suction nozzle 502, and a buffer elastic member 505 is provided between the lower limit portion 504 and the material picking base block 501.

The upper guide member and the lower guide member can be but are not limited to linear bearings or oil-free bushings.

[0091] In some examples, the upper limit portion 503 is a locking block sleeved on the outside of the suction nozzle 502, and the bolt is screwed into the locking block and the head thereof abuts against the outer peripheral wall of the suction nozzle 502, so that the locking block and the suction nozzle 502 can be locked, and the height of the suction nozzle 502 can be adjusted after the bolt is loosened, and the portion where the outer peripheral wall of the suction nozzle 502 abuts against the bolt is a flat structure;

[0092] The fixing block 506 is provided with a through groove 5061 for the locking block to pass through and fix the locking block circumferentially, and the through groove 5061 is a U-shaped groove;

[0093] In order to increase the speed of material collection, multiple suction nozzles 502 are arranged side by side for synchronous suction. At the same time, since the spacing between adjacent chips is small, the spacing between corresponding adjacent suction nozzles 502 is also small, so the installation space of the suction nozzle 502 is limited. In order to improve the installation and replacement efficiency of the suction nozzle 502, the suction nozzle 502 can be locked by a locking block and the height of the suction nozzle 502 can be adjusted. At the same time, the locking block and the through groove 5061 can cooperate to prevent the suction nozzle 502 from rotating.

[0094] In some examples, such as Fig.16 As shown, the jig 16 includes a carrier 1602 for carrying the chip and guide wheels 1603 arranged on both sides of the carrier 1602. The guide wheels 1603 cooperate with the tracks on the production line to convert sliding friction into rolling friction to reduce friction and avoid jamming of the jig 16 during its movement. The jig 16 begins to have a clamping groove 1604 for the clamping arm 1101 of the jig robot 11 to clamp, and the clamping groove 1604 and the locking groove 1601 are staggered with each other.

[0095] Working principle:

[0096] First, the jig 16 enters the combined preheating zone 1 through the entrance 1b, and the loading robot 17 grabs the chip into the receiving slot 1606 of the jig 16. After the current jig 16 is full of chips, the first pushing mechanism 4 pushes the current jig 16 to move toward the high-temperature curing zone 2. The jigs 16 interact with each other and move synchronously. The jigs 16 are preheated while waiting for loading and moving toward the high-temperature curing zone 2 after loading.

[0097] When the clamping jaw 901 moves the clamped pressure-applying body 8 to the top of the jig 16 at the entrance of the high-temperature curing zone 2, the pressure-applying body 8 and the jig 16 are initially positioned by inserting the positioning protrusion 1605 into the positioning groove, and then the clamping jaw 901 releases the pressure-applying body 8, and the second elastic member 805 resets to drive the locking hook 804 to rotate to hook with the jig 16, locking the pressure-applying body 8 and the jig 16 to form a combined structure, and the pressure rod 802 presses the chip under the elastic force of the first elastic member 803, and then the combined structure formed by the jig 16 and the pressure-applying body 8 pressed thereon enters the high-temperature curing zone 2 under the push of the first pushing mechanism 4, and the glue is cured to fix the magnetic core and the upper cover, the curing temperature is 150°C, and the curing time is 20 minutes;

[0098] After the curing is completed, the combined structure enters the heat preservation zone 3, and the clamping jaws 901 move to the top of the combined structure. When the clamping jaws 901 clamp the pressure-applying body 8, the clamping jaws 901 push the locking hook 804, so that the locking hook 804 overcomes the resistance of the second elastic member 805 and rotates to separate from the fixture 16. At the same time, the clamping jaws 901 transport the clamped pressure-applying component body to the entrance of the high-temperature curing zone 2 for the next round of pressure application.
