Abstract

The present invention relates to the technical field of chip production, and particularly to a self-unlocking chip pressurizing mold and a curing unit, which comprise a pressurizing component and a handling component. The pressurizing component includes a mold body, a pressure column, a first elastic member, a lock catch, and a second elastic member for applying pressure to the lock catch to hook and lock the lock catch with the jig. The handling component includes a clamp for clamping the mold body to carry out handling thereon, and when the clamp clamps, it applies pressure to the lock catch to enable the lock catch to rotate and separate from the jig against the acting force of the second elastic member. The present invention utilizes the cooperation between the clamp of the handling component and the lock catch on the mold. After the clamp transports the mold above the jig and releases the mold, the lock catch automatically locks the jig under the elastic force of the first elastic member. Then, during the process of the clamp clamping the mold, the lock catch rotates under force and disengages from the jig to achieve automatic unlocking. Thus, the locking and unlocking of the jig are synchronously realized during the handling process, meeting the requirements of in-line curing, and thereby improving the curing efficiency.

Description

Technical Field

[0001] The present invention relates to the technical field of chip production, and in particular to a self-unlocking chip pressurizing mold and a curing unit. Background Art

[0002] During the chip production process, the magnetic core and the upper cover need to be assembled. The two are generally assembled by applying glue on the upper surface of the magnetic core and then covering it with the upper cover. The two that are initially bonded are then sent to an oven for baking to solidify the glue. In order to increase the connection strength between the magnetic core and the upper cover during baking, the chip needs to be pressurized by a pressurized mold during baking. Chip baking is generally an assembly line operation. How to quickly lock the mold and the jig used to carry the chip for pressurization during baking, and quickly release the lock of the jig and the mold after baking is completed has become an urgent problem to be solved. Summary of the invention

[0003] The technical problem to be solved by the present invention is: in order to solve the problem that in the prior art the mold and the chip need to be locked when the chip is baked, and the lock needs to be unlocked after the baking is completed, and both locking and unlocking are time-consuming and cannot meet the problem of continuous water baking, a self-unlocking chip pressurizing mold and a curing unit are now provided.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solution: a self-unlocking chip pressurizing mold, which cooperates with a jig for carrying a chip to lock the jig and apply pressure to the chip on the jig when the chip enters a curing device, and automatically separates from the jig after the chip is cured. The pressurizing mold includes:

[0005] The pressurizing assembly includes a mold body, a press column slidably disposed in the mold body and extending out of the mold body toward the chip, a first elastic member for applying pressure to the press column so that the press column presses the chip, a lock hingedly disposed on the mold body, and a second elastic member for applying pressure to the lock so that the lock is hooked and locked with the fixture;

[0006] And a handling component, including a clamping claw for clamping the mold body to carry it, and the clamping claw presses the lock buckle while clamping so that the lock buckle overcomes the force of the second elastic member and rotates and separates from the fixture.

[0007] Furthermore, the outer wall of the fixture is recessed to form a hook groove, one end of the lock buckle is a hook claw for embedding into the hook groove, and the other end is a pressure-bearing part for cooperating with the second elastic member and the clamping claw.

[0008] Furthermore, the mold body is provided with a limiting groove for accommodating the lock buckle and limiting its rotation range.

[0009] Further, the jaw includes a holding portion for holding the mold body and a pressing portion for pressing the pressed portion, and the mold body has a holding step for cooperating with the holding portion.

[0010] Further, a sliding groove for the pressure column to slide is formed in the mold body, and an elastic holding block is adjustably provided at one end of the sliding groove away from the chip. A guiding rod protrudes from the pressure column towards the sliding groove, and the first elastic member is sleeved on the guiding rod. One end of the first elastic member abuts against the pressure column, and the other end abuts against the elastic holding block.

[0011] Further, a pressing block matching the chip is fixed at one end of the pressure column close to the chip, and the pressing block has a limiting surface for abutting against the mold body to limit its sliding into the sliding groove. The pressure column protrudes radially with a limiting protrusion for limiting its sliding out of the sliding groove.

[0012] Further, the handling assembly further includes a jaw seat for installing the jaws, a clamping driving mechanism for driving the two jaws to approach or separate from each other, a lifting driving mechanism for driving the jaws to lift, a handling driving mechanism for driving the jaw seat to approach or separate from the mold body, and a limiting column provided between the jaw seat and the mold body to limit the mold body.

[0013] Further, the handling assembly further includes a jaw fine-tuning mechanism, which includes an adjusting screw threadedly connected to the jaw and a contact surface located on the jaw seat and used for abutting against the adjusting screw to adjust the position of the jaw by rotating the adjusting screw.

[0014] A curing unit includes a curing device for heating and curing the chip, a conveying line for conveying the chip, and the above-mentioned pressurizing mold.

[0015] Further, a limiting block is provided at the end of the conveying line and abuts against the upper surface of the fixture to always limit the fixture on the conveying line when the mold body is separated from the fixture.

[0016] Advantages of the present invention: The present invention utilizes the cooperation between the jaws of the handling assembly and the lock on the mold. After the jaws transport the mold above the fixture and release the mold, the lock automatically locks the fixture under the elastic force of the first elastic member. Then, during the process of the jaws clamping the mold, the lock rotates under force and disengages from the fixture to achieve automatic unlocking. Thus, the locking and unlocking of the fixture are synchronously realized during the handling process, meeting the requirements of in-line curing and improving the curing efficiency.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner. Therefore, they only show the components related to the present invention, and directions and references (such as up, down, left, right, etc.) can only be used to assist in the description of the features in the drawings. Therefore, the following specific embodiments are not adopted in a restrictive sense, and the scope of the claimed subject matter is only defined by the appended claims and their equivalents.

[0033] As Figures 1 - 3 shown, a self-unlocking chip pressurizing mold is used in cooperation with a jig 3 for carrying chips. A plurality of spaced-apart chip grooves are provided on the upper surface of the jig 3, and each chip groove houses a chip. The chip includes a magnetic core and an upper cover covering the magnetic core. After dispensing glue between the two by a dispensing device to bond them, it is necessary to cure the glue at a high temperature through a curing device 4 to fix the magnetic core and the upper cover. The chip pressurizing mold locks the jig 3 and applies pressure to the chips on the jig 3 when the chips enter the curing device 4, so that the glue cures under a certain pressure to improve the structural strength between the magnetic core and the upper cover, and the chip pressurizing mold can be automatically separated from the jig 3 after the chips are cured. The pressurizing mold includes a pressurizing component 1 and a handling component 2.

[0034] The pressurizing component 1 includes a mold body 101, a pressure column 102 slidably disposed in the mold body 101 and extending out of the mold body 101 towards the chips, a first elastic member 103 for applying pressure to the pressure column 102 to pressurize the chips, a latch 104 hingedly disposed on the mold body 101, and a second elastic member 105 for applying pressure to the latch 104 to hook and lock the latch 104 with the jig 3. A positioning pin 302 is installed on the jig 3, and a positioning groove for the positioning pin 302 to insert to preliminarily position the mold body 101 and the jig 3 is provided on the mold body 101. Moreover, a plurality of support protrusions 1016 protrude from the bottom of the mold body 101. Both the first elastic member 103 and the second elastic member 105 are springs;

[0035] There are a plurality of pressure columns 102 and first elastic members 103, which correspond to the plurality of chips one by one. Each pressure column 102 is used to press the corresponding chip, so that the glue between the magnetic core and the upper cover cures under a certain pressure.

[0036] The handling component 2 includes jaws 201 for clamping the mold body 101 to carry it. Moreover, the jaws 201 apply pressure to the latch 104 while clamping, so that the latch 104 rotates and separates from the jig 3 against the action of the second elastic member 105. The number of jaws 201 can be two, and the two jaws 201 can approach or move away from each other to clamp or release the mold body 101.

[0037] First, the jaw 201 of the handling component 2 transports the mold body 101 it holds above the fixture 3. The positioning pin 302 is inserted into the positioning groove to preliminarily position the mold body 101 and the fixture 3 until the support protrusion 1016 of the mold body 101 abuts against the upper surface of the fixture. Then, the jaw 201 releases the mold body 101, and the second elastic member 105 resets to drive the latch 104 to rotate and hook onto the fixture 3, thereby locking the mold body 101 and the fixture 3. The pressing post 102 presses the chip under the elastic force of the first elastic member 103. Then, the assembly formed by the mold body 101 and the fixture 3 enters the curing device 4 along the conveyor line 5. The curing device 4 cures the adhesive liquid between the magnetic core and the upper cover at high temperature, thereby realizing the fixation of the magnetic core and the upper cover. Then, the assembly exits the curing device 4 along the conveyor line 5. The handling component 2 moves to the position of the assembly. When the jaw 201 clamps the mold body 101, the jaw 201 pushes the latch 104, causing the latch 104 to rotate around the hinge point against the resistance of the second elastic member 105 and separate from the fixture 3. At the same time, the jaw 201 removes the mold body 101 it holds to perform the pressing of the next group of chips. In this embodiment, when the handling component 2 transports the mold body 101 above the fixture 3, the pressing component 1 automatically locks the fixture 3 while the jaw 201 releases. And when the handling component 2 removes the mold body 101, the pressing component 1 automatically unlocks the fixture 3 while the jaw 201 clamps, realizing the automatic locking and unlocking of the fixture 3 and improving the curing efficiency.

[0038] In some examples, as Figure 3 shown, a hook groove 301 is formed by a depression on the outer peripheral wall of the fixture 3. One end of the latch 104 is a hook claw 1041 for embedding in the hook groove 301, which is formed by bending the end of the latch 104 upward. The hook claw 1041 can rotate and embed in the hook groove 301 under the elastic force of the second elastic member 105 to realize the locking of the mold body 101 and the fixture 3, and rotate out of the hook groove 301 under the action of the jaw 201 to realize the unlocking of the mold body 101 and the fixture 3. The other end of the latch 104 is a pressure-receiving part 1042 for cooperating with the second elastic member 105 and the jaw 201. The cross-sectional area of the pressure-receiving part 1042 is larger than the cross-sectional area of the hook claw 1041.

[0039] In some examples, as Figure 5 shown, the mold body 101 is provided with a limit groove 1011 for accommodating the latch 104 and limiting its rotation amplitude. The limit groove 1011 is generally rectangular.

[0040] In some examples, as Figure 3As shown, the clamp 201 includes a supporting portion 2011 for supporting the mold body 101 and a pushing portion 2012 for pushing the pressed portion 1042. The pressed portion 1042 of the lock buckle 104 extends out of the limiting groove 1011 to cooperate with the pushing portion 2012. A connecting portion 2013 is provided between the pushing portion 2012 and the supporting portion 2011, and the mold body 101 has a supporting step 1012 for cooperating with the supporting portion 2011. When the clamp 201 is used for carrying, its supporting portion 2011 cooperates with the supporting step 1012 to support the mold body 101, and at the same time, the pushing portion 2012 applies pressure to the pressed portion 1042 to rotate the hook 1041.

[0041] In some examples, such as Figure 3 and Figure 4 As shown, a slide groove 1013 for the pressure column 102 to slide is formed in the mold body 101, and an elastic retaining block 106 is adjustable at one end of the slide groove 1013 away from the chip, and a guide rod 107 is formed on the pressure column 102 protruding in the direction of the elastic retaining block 106, and the first elastic member 103 is sleeved on the guide rod 107 and one end of the first elastic member 103 abuts against the pressure column 102, and the other end abuts against the elastic retaining block 106, and the compression amount of the first elastic member 103 can be adjusted by adjusting the upper and lower positions of the elastic retaining block 106, thereby adjusting the pressure exerted by the first elastic member 103 on the pressure column 102;

[0042] Preferably, the mold body 101 includes a cover plate 1014 and a base 1015 which are fixedly connected, the cover plate 1014 protrudes from the base 1015 so that the above-mentioned supporting step 1012 is formed therebetween, an upper groove is provided inside the cover plate 1014, and a lower groove is provided inside the base 1015, the upper groove and the lower groove are combined to form the above-mentioned slide groove 1013, the upper groove is smaller at the top and larger at the bottom to form a limiting step for limiting the elastic retaining block 106, the elastic retaining block 106 is knocked into the upper groove from bottom to top by a tool and has an interference fit with the upper groove.

[0043] In some examples, such as Figure 4 As shown, a pressure block 108 matching the chip is fixed to one end of the pressure column 102 close to the chip, which can avoid the chip from tilting due to uneven pressure, and the pressure block 108 has a limiting surface that abuts against the mold body 101 to limit its sliding into the slide groove 1013. The pressure column 102 has a limiting protrusion 1021 protruding radially for limiting its sliding out of the slide groove 1013. The limiting surface and the limiting protrusion cooperate to limit the movement range of the pressure column 102.

[0044] In some examples, such as Figure 6As shown, the handling assembly 2 further includes a jaw seat 202 for mounting the jaws 201, a clamping drive mechanism 203 for driving the two jaws 201 to approach or separate from each other, a lifting drive mechanism 204 for driving the jaws 201 to lift, a handling drive mechanism 205 for driving the jaw seat 202 to approach or separate from the mold body 101, and a limit post 206 disposed between the jaw seat 202 and the mold body 101 to limit the mold body 101. The clamping drive mechanism 203, the lifting drive mechanism 204, and the handling drive mechanism 205 can be, but are not limited to, cylinders, linear modules, etc.;

[0045] Sliders are installed on the jaws 201, and slide rails mating with the sliders are installed on the jaw seat 202. When the clamping drive mechanism 203 drives the jaws 201 to approach or separate from each other, the cooperation between the sliders and the slide rails can guide the movement of the jaws 201.

[0046] In some examples, as Figure 1 shown, the handling assembly 2 further includes a jaw fine-tuning mechanism, which includes an adjusting screw 207 threadedly connected to the jaw 201 and an abutting surface 2021 located on the jaw seat 202 and used to abut against the adjusting screw 207 to adjust the position of the jaw 201 by rotating the adjusting screw 207. A nut for fixing its position is installed on the adjusting screw 207. When the head of the adjusting screw 207 abuts against the jaw seat 202, the minimum distance between the jaw 201 and the jaw seat 202 can be adjusted by rotating the adjusting screw 207, so that the pressure exerted on the lock catch 104 when the jaw 201 clamps the mold body 101 can be slightly adjusted.

[0047] In some examples, as Figure 7 shown, a curing unit includes a curing device 4 for heating and curing the chip, a conveying line 5 for conveying the chip, and the above self-unlocking chip pressing mold. The curing device 4 can be, but is not limited to, an oven. The curing device 4 is erected on the conveying line 5 and divides the conveying line 5 into an input section at the front end, a curing section in the middle, and an output section at the end along the conveying direction of the fixture 3. In the input section, the handling assembly 2 locks the mold body 101 and the fixture 3 to form an assembly. In the curing section, the curing device 4 bakes the assembly. In the output section, the handling assembly 2 removes the mold body 101 from the fixture 3.

[0048] In some examples, as Figure 8As shown, a limit block 501 is provided at the end of the conveyor line 5, which abuts against the upper surface of the fixture 3 to always limit the fixture 3 on the conveyor line 5 when the mold body 101 is separated from the fixture 3. After the assembly of the fixture 3 and the mold body 101 is output from the curing device 4, the jaw 201 presses on the latch 104 to separate the latch 104 from the fixture 3. However, since the curing device 4 uses high-temperature curing and the mold body 101 continuously presses on the fixture 3 during the high-temperature curing process, there is still a risk of adhesion between the latch 104 and the fixture 3 after they are unlocked. The fixture 3 has a tendency to move up with the mold body 101, and the setting of the limit block 501 can intercept the fixture 3.

[0049] Working principle:

[0050] First, the jaw 201 of the handling assembly 2 transports the mold body 101 it holds above the fixture 3, and the mold body 101 and the fixture 3 are preliminarily positioned by inserting the positioning pin 302 into the positioning groove. Then the jaw 201 releases the mold body 101, and the second elastic member 105 resets to drive the latch 104 to rotate and hook with the fixture 3 to lock the mold body 101 and the fixture 3. The pressure post 102 presses on the chip under the elastic force of the first elastic member 103. Then the assembly formed by the mold body 101 and the fixture 3 enters the curing device 4 along the conveyor line 5, and the curing device 4 cures the adhesive liquid between the magnetic core and the upper cover at high temperature, thereby realizing the fixation of the magnetic core and the upper cover. Then the assembly exits the curing device 4 along the conveyor line 5. The handling assembly 2 moves to the position of the assembly. When the jaw 201 clamps the mold body 101, the jaw 201 pushes the latch 104, causing the latch 104 to rotate around the hinge point against the resistance of the second elastic member 105 and separate from the fixture 3. At the same time, the jaw 201 transports the mold body 101 it holds away to pressurize the next group of chips.
