Description

Technical Field

[0001] The invention relates to the technical field of electronic component processing, in particular to an inductor testing and packaging machine. Background Art

[0002] Inductors, transformers, filters, etc. are all electronic components, and are important components of electronic components and small machines and instruments. Among them, the inductor mainly includes a seat body and a winding body. The seat system buries the winding body in metal magnetic powder by die-casting. Two surface mount pins are provided on the seat body. The surface mount pins serve as the lead pins of the winding body. The two surface mount pins are electrically connected to the two ends of the winding body, and the two surface mount pins are located on opposite sides of the seat body. In order to ensure that the inductor has certain insulation performance, the inductor needs to be subjected to a withstand voltage test during the inductor production process. When the inductor is subjected to the withstand voltage test, the first detection end of the test instrument is electrically connected to the first pin of the inductor, the second detection end of the test instrument is electrically connected to the seat body of the inductor, and the second pin of the inductor is electrically connected to the seat body.

[0003] In addition, in order to improve the production efficiency and product quality of electrical components, the existing production mode of electrical components has gradually transitioned from the traditional manual operation mode to the mechanical automation operation mode. For example, an inductor test packaging machine is used to automatically feed, unload, withstand voltage test, interlayer withstand voltage test, inkjet, size detection, packaging, etc. However, the existing inductor test packaging machine has the following disadvantages: the withstand voltage test tooling has multiple single test channels and uses the turntable loading device of the inductor test packaging machine. In addition, since the withstand voltage test takes a long time, generally about 3.5 seconds, while other processes take a short time, it is difficult to further improve the production efficiency of the inductor test packaging machine. Summary of the invention

[0004] In order to solve the above problems, the main object of the present invention is to provide an inductor testing and packaging machine with high production efficiency.

[0005] In order to achieve the main purpose of the present invention, the present invention provides an inductor testing and packaging machine, which includes a feeding device, a withstand voltage testing device and a turntable feeding device, the withstand voltage testing device includes a withstand voltage testing tool and a first transplanting unit, the withstand voltage testing tool includes an upper seat and a base, a test unit and a first pin unit are arranged on the upper seat, the test unit includes more than two test positions, a first probe, a second probe, a third probe and a fourth probe are arranged in the test position, the first probe and the third probe are distributed along a first direction, the second probe and the fourth probe are distributed along a second direction, a resistor is connected between the third probe and the fourth probe, the first pin unit includes more than two groups of first needle groups, the more than two groups of first needle groups are connected to two The above test positions correspond one to one, the first pin group includes a first pin and a second pin, the first pin is electrically connected to the first probe, and the second pin is electrically connected to the second probe, a second pin unit is arranged on the base, the second pin unit includes more than two groups of second pin groups, and the more than two groups of second pin groups correspond one to one with the more than two groups of first pin groups, the second pin group includes a third pin and a fourth pin, and a first assembly position is provided between the upper seat and the base, in the first assembly position, the third pin is electrically connected to the first pin, and the fourth pin is electrically connected to the second pin, the first transplanting unit includes a first driving mechanism and a grasping mechanism, and the first driving mechanism can drive the grasping mechanism to move between the feeding device, the withstand voltage test fixture and the turntable feeding device.

[0006] As can be seen from the above, the feeding device is used to supply inductors to the voltage test device in an orderly manner, so that the first transfer unit can transfer the inductors to the voltage test tooling for voltage test; and through the structural design of the voltage test tooling, the voltage test tooling can perform voltage test on more than two inductors at the same time, which effectively improves the test efficiency and better reduces the waiting time of the turntable loading device; the turntable loading device is used to transfer the inductors that pass the voltage test to other devices for corresponding subsequent processing and / or testing.

[0007] A preferred solution is that more than two test positions are distributed along the first direction, more than two groups of first pin groups are distributed along the first direction, more than two groups of second pin groups are distributed along the first direction, the first pin and the second pin are distributed along the third direction, the third pin and the fourth pin are distributed along the third direction, the third direction is perpendicular to the first direction, and there is a second assembly position between the upper seat and the base, and in the second assembly position, the third pin is electrically connected to the second pin, and the fourth pin is electrically connected to the first pin.

[0008] As can be seen from the above, the above structural design allows the withstand voltage test fixture to be suitable for different types of inductors by changing the assembly relationship between the upper seat and the base when the type of inductor changes (such as the central angle of the pin position between two different types of inductors differs by 90°), thereby effectively expanding the compatibility of the withstand voltage test fixture.

[0009] Another preferred scheme is that the feeding device includes a feeding unit, a second transplanting unit and a transfer unit, the feeding unit includes a base frame, a transfer mechanism and a material dividing mechanism, the base frame has a unloading station and a material picking station distributed along a fourth direction, a storage bin is arranged at the unloading station, the transfer mechanism includes a tray and a first drive assembly, the tray is located below the storage bin, the first drive assembly can drive the tray to move between the outlet of the storage bin and the material picking station in the fourth direction, the material dividing mechanism includes a material dividing terminal and a second drive assembly, the material dividing terminal is located between the outlet and the tray, the second drive assembly is installed on the base frame, the second drive assembly can drive the material dividing terminal to move toward or back to the storage bin, so that on the bearing surface of the tray, at least a part of the projection of the material dividing terminal is located within the projection of the outlet or the projection of the material dividing terminal is located outside the projection of the outlet, the second transplanting unit includes a pick-up and placement mechanism and a second drive mechanism, the transfer unit includes a third drive mechanism and a carrier, the third drive mechanism can drive the carrier to move to the first transplanting unit, and the second drive mechanism can drive the pick-up and placement mechanism to move to the transfer unit.

[0010] As can be seen from the above, the storage bin of the feeding unit is used to stack and store the trays with inductors, and the material distribution mechanism moves the trays of the storage bin one by one onto the tray of the transfer mechanism through the action of the material distribution end, and then the first drive assembly transfers the tray after receiving the tray to the material picking station. The second transfer unit drives the pick-up and placement mechanism at the material picking station and the rear unit of the first transfer unit through the second drive mechanism, and then transfers the inductors on the trays to the withstand voltage detection device in an orderly manner. Through the structural design of the feeding device, the feeding device can effectively prevent the inductor from being worn when transferring the inductor to the withstand voltage detection device, which protects the electrical components and reduces the unqualified rate of the product.

[0011] A further solution is that the feeding unit also includes two lifting mechanisms, both of which are arranged at the unloading station, and the two lifting mechanisms are respectively located on the opposite sides of the transfer mechanism, and the lifting mechanism includes a third drive assembly and a support block, and the third drive assembly is installed on the base frame. The third drive assembly can drive the support block to move between the material distribution end and the pallet in the dropping direction of the storage bin.

[0012] As can be seen from the above, by providing a lifting mechanism, when the material distribution mechanism lowers the material trays in the storage bin onto the tray one by one, the material trays can fall onto the tray smoothly and accurately, thereby ensuring that the pick-up and placement mechanism of the transplanting unit can accurately absorb the inductor on the material tray and avoid the inductor on the material tray being impacted and scattered on the material tray or falling out of the material tray during the falling process.

[0013] A further solution is that the base frame also has a recycling station located at the downstream end of the material picking station, and a recycling bin is arranged at the recycling station. The first driving component can also drive the tray to move in the first direction to the entrance of the recycling bin. The feeding unit also includes a material clamping mechanism and two pushing mechanisms. The material clamping mechanism includes a material clamping end and a fourth driving component. The material clamping end is located between the entrance and the tray. The fourth driving component is installed on the base frame. The fourth driving component can drive the material clamping end to move toward the recycling bin so that on the bearing surface, at least a part of the projection of the material clamping end is located within the projection of the entrance. The two pushing mechanisms are both arranged at the recycling station, and the two pushing mechanisms are respectively located on opposite sides of the transfer mechanism. The pushing mechanism includes a fifth driving component and a pushing block. The fifth driving component is installed on the base frame. The fifth driving component can drive the pushing block to move between the material clamping end and the tray in the feeding direction of the recycling bin.

[0014] As can be seen from the above, the above structural design enables the first drive component to drive the tray to transfer the empty tray to the recycling station after the inductors on the tray are taken away by the second transfer unit, and then the pushing mechanism cooperates with the clamping mechanism to stack the empty trays into the recycling bin to recycle the empty trays.

[0015] A further solution is that the clamping end is a first claw, the fourth drive assembly includes a first seat body and a first elastic member, the first claw is rotatably connected to the first seat body around a first rotation axis, and the first elastic member forces the claw portion of the first claw to move toward the recovery bin; and / or the material distribution end is a second claw, the second drive assembly includes a second seat body, a second elastic member and a first cylinder, the second claw is rotatably connected to the second seat body around a second rotation axis, the second elastic member forces the claw portion of the second claw to move toward the storage bin, and the first cylinder drives the claw portion of the second claw to move back to the storage bin.

[0016] As can be seen from the above, the above structural design makes it possible for the opening mechanism to cooperate with the pushing mechanism to stack the empty material trays into the recovery bin without the need for electrical control elements to control the material clamping mechanism, making the programming of the feeding device simpler, and also ensuring the smoothness of the empty material trays when being pushed into the recovery bin and preventing the empty material trays from escaping from the entrance of the recovery bin after entering the recovery bin; in addition, when the material dividing mechanism lowers the material trays in the storage bin onto the pallet one by one, the first cylinder first drives the claw of the second clamping claw to move back toward the storage bin, so that the second clamping claw releases the obstruction of the first material tray closest to the exit of the bin, and then the first material tray falls onto the pallet, and then the first cylinder is reset, and the claw of the second clamping claw moves toward the storage bin under the action of the elastic potential energy of the second elastic member, and then blocks the second material tray above the first material tray, so as to realize the lowering of the material trays onto the pallet one by one.

[0017] A further solution is that the turntable loading device includes a turntable, a drive unit and a first direct vibration unit, the turntable is provided with a suction module distributed along its own circumference, the suction module includes a base, a suction unit, a limit stop, a third elastic member and an adjusting hand wheel, the suction unit includes an air column and a suction nozzle, the air column penetrates the base along its own axial direction, the suction nozzle is installed at the first end of the air column and is connected with the air column, the limit stop is installed at the second end of the air column, the base is located between the suction nozzle and the limit stop, the third elastic member forces the suction nozzle to move axially away from the base, the adjusting hand wheel is rotatably installed on the base around its own rotation axis, the rotation axis is perpendicular to the axial direction, the adjusting hand wheel has an adjusting portion, at least one mating surface is formed on the peripheral wall of the adjusting portion, the limit stop can be adjacent to a mating surface or the base, the adjusting portion can adjust the vertical distance between the limit stop and the rotation axis in the axial direction through the mating surface, the drive unit drives the turntable to rotate, each suction module can be moved to the first direct vibration unit, and the first drive mechanism can drive the grabbing mechanism to move to the first direct vibration unit.

[0018] As can be seen from the above, the adjustment part of the adjustment hand wheel can be matched in advance according to the number of inductors of different heights that the suction module needs to adapt and the height value of the inductor, so that each mating surface on the adjustment part can correspond to an inductor of different heights, so that when the height value of the inductor in the west area required by the suction module changes, the adjustment hand wheel can be turned to make a corresponding mating surface on the adjustment hand wheel contact with the limit block, or the limit block can be directly contacted with the base to adjust the vertical distance between the limit block and the rotation axis in the axial direction, and the limit block adjusts the relative position of the suction nozzle in the axial direction through the air column, so that the suction nozzle can adapt to the height of the inductor, ensuring that the suction module can reliably absorb the inductor and avoid damage to the inductor. Through the structural design of the suction module, when the height of the inductor changes, the position of the suction nozzle can be adjusted by adjusting the adjustment hand wheel, so that there is no need to replace the suction nozzles of the suction module one by one, and the production efficiency and compatibility of the suction module can be better improved.

[0019] A further solution is that the mating surface is a plane; and / or the number of mating surfaces is two to six, each mating surface has a maximum vertical distance with the axis of rotation, the two to six maximum vertical distances are not equal, or at least two of the two to six maximum vertical distances are not equal.

[0020] As can be seen from the above, setting the mating surface as a plane can ensure the stability and reliability when the mating surface contacts the limit block; and the number of mating surfaces and the maximum vertical distance between the mating surface and the rotation axis can be adjusted accordingly according to the number of inductors of different heights that the suction module needs to adapt and the height value of the inductor, so that the suction module can be suitable for multiple inductors of different heights.

[0021] A further solution is that the base is provided with an arcuate groove at one end near the limit stop, the adjusting hand wheel also has a rotating part and an operating part, the rotating part is located between the adjusting part and the operating part, the adjusting part and the rotating part are both located in the arcuate groove, the suction module also includes a fixing bolt, the fixing bolt passes through the adjusting hand wheel and is threadedly connected to the base, and the rotating part can rotate around the rotation axis in the arcuate groove.

[0022] As can be seen from the above, the arc groove on the base can properly support and limit the rotating part of the adjusting hand wheel, so that the adjusting hand wheel can rotate more stably and reliably, and the fixing bolt is used to fix the adjusting hand wheel on the base.

[0023] A further solution is that the suction module also includes a sleeve and a spring plunger, the adjusting hand wheel is rotatably mounted on the sleeve around the rotation axis, the fixing bolt passes through the sleeve, and more than two limit grooves are provided on the side of the operating part facing the base, the more than two limit grooves are distributed around the rotation axis, the spring plunger is installed on the base, and when the limit block is adjacent to the mating surface or the base, the positioning bead of the spring plunger engages with one of the more than two limit grooves.

[0024] As can be seen from the above, the above design enables the fixing bolt to fix the adjusting handwheel to the base through the shaft sleeve, and at the same time, the handwheel can be adjusted in real time without operating the adjusting bolt during the rotation process; in addition, after each rotation of the adjusting handwheel is completed, the spring plunger can limit the adjusting handwheel through the limiting groove on the operating part to prevent the adjusting handwheel from rotating in a non-adjustment state.

Figure 2 and 3 The feeding unit 1 includes a base frame 11, a transfer mechanism 12, a material distribution mechanism 13, a lifting mechanism 14, a material clamping mechanism 15 and a pushing mechanism 16. The base frame 11 has a material unloading station 111, a material picking station 112 and a recycling station 113. The material unloading station 111, the material picking station 112 and the recycling station 113 are sequentially distributed along the fourth direction, and the fourth direction is opposite to the first direction X. A storage bin 1111 is provided at the material unloading station 111, and the storage bin 1111 is used to store the material tray 33 with the inductor placed thereon; a recycling bin 1131 is provided at the recycling station 113, and the recycling bin 1131 is used to recycle the empty material tray 33.

[0050] The transfer mechanism 12 is used to transfer the material tray 33 from the storage bin 1111 of the unloading station 111 to the material taking station 112, so that the second transfer unit 2 can take away the inductor on the material tray 33. In addition, the transfer mechanism 12 is also used to transfer the material tray 33 from the material taking station 112 to the recycling station 113, so that when all the inductors on the material tray 33 are taken away, the empty material tray 33 can be automatically recycled into the recycling bin 1131. Specifically, the transfer mechanism 12 includes a tray 121 and a first drive assembly 122.

[0051] In the material dropping direction of the storage bin 1111, the tray 121 is located below the storage bin 1111, and the tray 121 is located below the recovery bin 1131; wherein the material dropping direction is opposite to the height direction Z of the pressure test device 103. The tray 121 is used to receive the material tray 33 dropped from the storage bin 1111, and the first driving assembly 122 is used to drive the tray 121 to move in the fourth direction, so that the tray 121 can move between the unloading station 111, the material picking station 112 and the recovery station 113, that is, the first driving assembly 122 can drive the tray 121 to move between the exit of the storage bin 1111, the material picking station 112 and the entrance of the recovery bin 1131. Specifically, in this embodiment, the first driving assembly 122 includes two pulleys 1221, a transmission belt 1222, a first motor 1223 and a first guide rail module 1224.

The setting of the first guide rail module 1224 makes the movement of the tray 121 more stable and reliable. It should be noted that in other embodiments, the first drive component 122 can be set to other structures, such as including a ball screw, a second motor and a second guide rail module. It can be seen that the structure of the first driving assembly 122 can be adjusted and changed accordingly according to conditions such as its installation space, the control requirements of the tray 121 and the production cost of the feeding device 102.

[0052] The material distribution mechanism 13 is disposed at the exit of the storage bin 1111, and is used to control the material trays 33 in the storage bin 1111 to be placed one by one on the tray 121. Figure 4 and Figure 5 The material distribution mechanism 13 includes a material distribution terminal 131 and a second driving component 132. In the material dropping direction, the material distribution terminal 131 is located between the outlet of the storage bin 1111 and the tray 121. The second driving component 132 is installed on the base frame 11. The second driving component 132 is used to drive the material distribution terminal 131 to move toward or away from the outlet of the storage bin 1111, so that on the bearing surface of the tray 121, at least a part of the projection of the material distribution terminal 131 can be located within the projection of the outlet of the storage bin 1111 or the projection of the material distribution terminal 131 is located outside the projection of the outlet of the storage bin 1111, thereby enabling the material distribution mechanism 13 to block the material tray 33 in the storage bin 1111 or enable the material distribution mechanism 13 to move the material tray 33 from below to above the material tray 33.

[0053] Specifically, in this embodiment, the material dispensing end 131 is a second claw, and the second driving assembly 132 includes a second seat body 1321 , a second elastic member 1322 and a first cylinder 1323 . Among them, the second seat body 1321 is fixedly installed on the base frame 11, and the second claw is rotatably connected to the second seat body 1321 around the second rotation axis, and the second rotation axis is parallel to the fourth direction; the second elastic member 1322 preferably adopts a second compression spring, and the second compression spring abuts between the second seat body 1321 and the second claw, and in the blanking direction, the second compression spring is located above the second rotation axis, and the second compression spring is used to force the second claw to rotate around the second rotation axis so that the claw portion of the second claw moves toward the outlet of the storage bin 1111; the first cylinder 1323 is installed on the second seat body 1321, and the piston rod of the first cylinder 1323 is parallel to the blanking direction, and in the blanking direction, the piston rod of the first cylinder 1323 is located below the second rotation axis, and the first cylinder 1323 is used to drive the second claw to rotate around the second rotation axis so that the claw portion of the second claw moves away from the outlet of the storage bin 1111. Preferably, a wedge-shaped portion 1311 is formed on the second clamping jaw, and a top head 1324 is arranged on the piston rod of the first cylinder 1323, the top head 1324 has an arc surface, the center line of the arc surface is parallel to the fourth direction, and the arc surface is adjacent to the inclined surface 1511 of the wedge-shaped portion 1311. By forming the wedge-shaped portion 1311 on the second clamping jaw and arranging the top head 1324 on the piston rod of the first cylinder 1323, the second driving assembly 132 can stably and reliably drive the claw of the second clamping jaw to move back toward the outlet of the storage bin 1111, and at the same time can also protect the piston rod of the first cylinder 1323 and the second clamping jaw.

[0054] Combination Figure 7The number of the lifting mechanisms 14 is preferably two, and both lifting mechanisms 14 are arranged at the material unloading station 111, and in the material unloading direction, the lifting mechanisms 14 are located below the outlet of the storage bin 1111. In addition, the two lifting mechanisms 14 are also located on opposite sides of the transfer mechanism 12, and the arrangement of the lifting mechanisms 14 enables the material trays 33 in the storage bin 1111 to be lowered one by one onto the tray 121 by the material distribution mechanism 13, so that the material trays 33 can be smoothly and accurately dropped onto the tray 121, thereby ensuring that the second transfer unit 2 can accurately absorb the inductor on the material tray 33, and preventing the inductor on the material tray 33 from being scattered on the material tray 33 or falling out of the material tray 33 due to impact during the falling process of the material tray 33. The lifting mechanism 14 includes a third driving component 1331 and a support block 142. The third driving component 1331 is installed on the base frame 11, and the third driving component 1331 preferably adopts a third cylinder. The support block 142 is fixedly connected to the piston rod of the third cylinder, so that the third cylinder can drive the support block 142 to move between the material distribution end 131 of the material distribution mechanism 13 and the tray 121 in the material dropping direction, so that when the material tray 33 in the storage bin 1111 falls to the tray 121, the third cylinder can first drive the support block 142 to move to the material distribution end 131 of the material distribution mechanism 13. When the material distribution mechanism 13 controls a material tray 33 in the storage bin 1111 to fall onto the support block 142, the third cylinder drives the support block 142 to move toward the tray 121, so that the material tray 33 on the support block 142 falls smoothly onto the tray 121.

[0055] Combination Figure 6The clamping mechanism 15 is arranged at the entrance of the recycling bin 1131, and is used to cooperate with the pushing mechanism 16 to stack the empty material trays 33 into the recycling bin 1131. The clamping mechanism 15 includes a clamping end 151 and a fourth driving assembly 152. In the feeding direction of the recycling bin 1131, the clamping end 151 is located between the entrance of the recycling bin 1131 and the tray 121, wherein the feeding direction is the same as the height direction Z. The fourth driving assembly 152 is used to drive the clamping end 151 to move toward the entrance of the recycling bin 1131, so that at least a part of the projection of the clamping end 151 on the bearing surface of the tray 121 can be located within the projection of the entrance of the recycling bin 1131, thereby realizing that the clamping end 151 blocks the material trays 33 in the recycling bin 1131. Specifically, in this embodiment, the clamping end 151 is a first claw, and the fourth driving assembly 152 includes a first seat 1521 and a first elastic member 1522. The first seat body 1521 is fixedly mounted on the base frame 11, and the first clamping claw is rotatably connected to the first seat body 1521 around a first rotation axis, and the first rotation axis is parallel to the fourth direction; the first elastic member 1522 preferably adopts a first compression spring, and the first compression spring abuts between the first seat body 1521 and the first clamping claw, and in the feeding direction, the first compression spring is located above the first rotation axis, and the first compression spring is used to force the first clamping claw to rotate around the first rotation axis so that the claw of the first clamping claw faces the recycled material. In addition, the side of the claw of the first claw facing the material tray 33 is preferably set in the form of an inclined surface 1511, that is, the inclined surface 1511 is inclined to the supporting surface of the material tray 33, so that when the material tray 33 moves toward the first claw, the material tray 33 can push the first claw to rotate around the first rotation axis through the inclined surface 1511, so that the claw of the first claw moves away from the outlet of the recovery bin 1131, and then the material tray 33 can move from the bottom of the claw of the first claw to the top of the claw of the first claw. It can be seen that through the structural design of the clamping mechanism 15, the empty material tray 33 does not need to rely on electrical components to control the clamping mechanism 15 during the stacking process, thereby making the feeding device 102 simpler. In addition, the structural design of the clamping mechanism 15 can also ensure the smoothness when the empty material tray 33 is pushed into the recovery bin 1131 and prevent the empty material tray 33 from escaping from the entrance of the recovery bin 1131 after entering the recovery bin 1131.

[0056] The number of the pushing mechanisms 16 is preferably two, and both of the pushing mechanisms 16 are arranged at the recycling station 113, and in the feeding direction, the positioning mechanism is located below the entrance of the recycling bin 1131. In addition, the two pushing mechanisms 16 are also located on opposite sides of the transfer mechanism 12, and the setting of the pushing mechanisms 16 enables the empty material tray 33 to be pushed toward the clamping end 151 when the transfer mechanism 12 transfers the empty material tray 33 to the recycling station 113, and then cooperates with the clamping mechanism 15 to stack the empty material tray 33 into the recycling bin 1131, so as to recycle the empty material tray 33. The pushing mechanism 16 includes a fifth driving component 161 and a pushing block 162. The fifth driving component 161 is installed on the base frame 11, and the fifth driving component 161 preferably adopts a fifth cylinder. The pushing block 162 is fixedly connected to the piston rod of the fifth cylinder, so that the fifth cylinder can drive the pushing block 162 to move between the clamping end 151 and the tray 121 in the feeding direction, so that when the tray 121 of the transfer mechanism 12 moves to the recycling station 113, the fifth cylinder can drive the pushing block 162 to move from the bottom of the tray 121 toward the clamping end 151, and then push the empty material tray 33 on the tray 121 toward the clamping end 151, so that the empty material tray 33 moves from the bottom of the claw of the first claw to the top of the claw of the first claw, so as to realize the stacking of the empty material tray 33 into the recycling bin 1131.

[0057] Combination Figure 8 The second transplanting unit 2 includes a pick-and-place mechanism 21 and a fourth drive mechanism 22. The fourth drive mechanism 22 can drive the pick-and-place mechanism 21 to move to the material picking station 112, so that the pick-and-place mechanism 21 can absorb the electrical components on the material tray 33 at the material picking station 112. In addition, the fourth drive mechanism 22 can also drive the pick-and-place mechanism 21 to move to the second direct vibration unit 31. Specifically, the fourth drive mechanism 22 includes a sixth drive assembly 211 and a seventh drive assembly 222, wherein the sixth drive assembly 211 includes a first linear module and a third motor, and the seventh drive assembly 222 is installed on the first slide of the first linear module, so that the third motor can drive the seventh drive assembly 222 to move in the second direction through the first linear module, wherein the third direction Y, the fourth direction and the blanking direction are perpendicular to each other, and the seventh drive assembly 222 includes a second linear module and a fourth motor.

[0058] The pick-and-place mechanism 21 includes a second cylinder 211, a suction seat 212 and a mounting frame 213. The piston rod of the second cylinder 211 is parallel to the material-dropping direction, and the second cylinder 211 is fixedly connected to the second slide of the second linear module, so that the fourth motor can drive the pick-and-place mechanism 21 to move in the material-dropping direction through the second linear module. The suction seat 212 is fixedly mounted on the slide of the second linear module, so that the suction seat 212 can move in the material-dropping direction with the barrel of the second cylinder 211, wherein a slide groove 2121 is provided in the suction seat 212, and the depth direction of the slide groove 2121 is parallel to the material-dropping direction. The mounting frame 213 is arranged in the slide groove 2121 and can move along the depth direction of the slide groove 2121. The mounting frame 213 is fixedly connected to the piston rod of the second cylinder 211, so that the second cylinder 211 can drive the mounting frame 213 to move in the slide groove 2121. In addition, a magnetic member is arranged on the side of the mounting frame 213 facing the material taking tray 121. The material suction seat 212 is used to contact with the inductor and play a certain protective role on the inductor to prevent the inductor from being worn during the suction process. When the pick-and-place mechanism 21 needs to absorb the inductor, the second cylinder 211 controls the mounting frame 213 to move toward the electrical component, that is, the second cylinder 211 controls the mounting frame 213 to move toward the bottom of the suction seat 212, so that the magnetic part on the mounting frame 213 absorbs the inductor; and when the pick-and-place mechanism 21 wants to release the absorption of the inductor, the second cylinder 211 drives the mounting frame 213 to move back to the inductor, that is, the second cylinder 211 controls the mounting frame 213 to move back to the bottom of the suction seat 212, so that the magnetic force of the magnetic part is not enough to absorb and fix the inductor on the suction seat 212, thereby causing the inductor to fall off the suction seat 212.

[0059] The transfer unit 32 includes a third driving mechanism 321 and a carrier 322. The third driving mechanism 321 can drive the carrier 322 to move between the second direct vibration unit 31 and the withstand voltage test device 103 in the first direction X. When the carrier 322 is located at the second direct vibration unit 31, the second direct vibration unit 31 can deliver the inductors one by one into the receiving slot of the carrier 322 with the cooperation of the third driving mechanism 321. In addition, in this embodiment, there are multiple trays 33, and multiple storage slots 331 are provided on the tray 33. The storage slots 331 are used to accommodate the inductors and limit the inductors so that the inductors can be neatly and orderly placed on the tray 33. Through the structural design of the feeding device, the feeding device can effectively prevent the inductors from being worn during the process of automatically feeding the withstand voltage test device, so as to reduce the defective rate of the product.

[0062] Combination Fig.13 and Fig.14, a second pin unit 421 is provided on the base 42, and in the present embodiment, the second pin unit 421 is located at the top of the base 42. The second pin unit 421 includes more than two groups of second pin groups 4210, and the more than two groups of second pin groups 4210 are preferably distributed along the first direction X, so that the multiple groups of second pin groups 4210 correspond to the multiple groups of first pin groups 4120 one by one.

In the second assembly position, the third pin 4211 cooperates with the second pin 4122 to achieve electrical connection between the third pin 4211 and the second pin 4122, and the fourth pin 4212 cooperates with the first pin 4121 to achieve electrical connection between the fourth pin 4212 and the first pin 4121. In addition, in this embodiment, the first pin 4121 and the second pin 4122 are both female pins, and the third pin 4211 and the fourth pin 4212 are both male pins.

[0063] It should be noted that, in other embodiments, the first pin unit 412 can also be arranged on the side of the upper seat 41. For example, each first pin group 4120 includes two first pins 4121 and two second pins 4122. The two first pins 4121 are respectively located on two opposite side walls of the upper seat 41, and the two second pins 4122 are distributed on the two aforementioned side walls. On the first side wall, the first pin 4121 is located directly above the second pin 4122; on the second side wall, the first pin 4121 is located directly below the second pin 4122; and the second pin unit 421 can be correspondingly arranged on a side wall of the base 42.

[0064] The recycling box 43 is arranged on one side of the upper seat 41. Preferably, the upper seat 41 and the recycling box 43 are distributed along the third direction Y, and the recycling box 43 is used to recycle the inductors that fail the withstand voltage test. The number of the proximity switch sensors 44 is more than two, and the more than two proximity switch sensors 44 are distributed along the first direction X, so that the more than two proximity switch sensors 44 correspond to the more than two groups of second needle groups 4210. In addition, the proximity switch sensor 44 is located at the entrance of the recycling box 43, and the recycling box 43 is located between the proximity switch sensor 44 and the upper seat 41. The proximity switch sensor 44 can detect whether the inductor that fails the withstand voltage test is put into the recycling box 43, so as to avoid the inductor that fails the withstand voltage test from participating in the subsequent production and processing, thereby better reducing the production cost and the defective rate of the product.

[0065] The number of test positions 4111 of the test unit 411 is preferably 2 to 10, the number of the first needle group 4120 is equal to the number of test positions 4111, the number of the second needle group 4210 is greater than or equal to the number of test positions 4111, and the number of proximity switch sensors 44 is equal to the number of the second needle group 4210.

The through-beam photoelectric sensor 45 is disposed at the upper seat 41, and in the first direction X, the transmitting end and the receiving end of the through-beam photoelectric sensor 45 are respectively located on opposite sides of the upper seat 41.

[0066] like Fig. 9 As shown, the first transplanting unit 5 includes a gripping mechanism 51 and a first driving mechanism 52. The gripping mechanism 51 is used to grip or place the inductor. The gripping mechanism 51 includes a connecting seat 511, a suction seat 512, a fourth compression spring 513 and a third guide rail module 514. A suction assembly is provided on the suction seat 512, and the suction assembly includes more than two suction nozzles 5121, and the more than two suction nozzles 5121 are distributed along the first direction X, so that the more than two suction nozzles 5121 correspond to the more than two test positions 4111 one by one, and the number of suction nozzles 5121 is preferably equal to the number of test positions 4111. Using the suction nozzle 5121 to grip the inductor can not only ensure the reliability of gripping, but also avoid the gripping mechanism 51 from interfering with the withstand voltage test of the inductor. In addition, a slide bar 5122 is provided on the suction seat 512, and the slide bar 5122 extends along the height direction of the first probe 4112, and the slide bar 5122 is slidably connected to the connection seat 511 along the height direction of the first probe 4112. The height direction of the first probe 4112 is parallel to the height direction Z of the withstand voltage test fixture 4.

[0067] The fourth compression spring 513 is sleeved on the slide bar 5122, and the two ends of the fourth compression spring 513 are respectively in contact with the connecting seat 511 and the material suction seat 512. The fourth compression spring 513 is used to force the material suction seat 512 to move toward the withstand voltage test fixture 4 in the height direction Z. The setting of the fourth compression spring 513 enables the material suction seat 512 to have a certain buffer space, so as to avoid a hard collision between the grasping mechanism 51, the inductor or other mechanisms (such as the carrier 322, the first straight vibration unit 62, etc.) when the grasping mechanism 51 grasps or places the inductor, thereby avoiding damage or destruction of the grasping mechanism 51, the inductor and other mechanisms. The third guide rail module 514 extends along the height direction Z, and the third guide rail module 514 is connected between the connecting seat 511 and the material suction seat 512. The setting of the third guide rail module 514 makes the movement of the material suction seat 512 more stable and reliable.

[0068] The first driving mechanism 52 includes an eighth driving assembly 521 and a ninth driving assembly 522. The eighth driving assembly 521 includes a third linear module 5211 and a third motor 5212. The ninth driving assembly 522 is mounted on the third slide of the third linear module 5211, so that the third motor 5212 can drive the ninth driving assembly 522 to move in the third direction Y through the third linear module 5211. The ninth driving assembly 522 includes a fourth linear module 5221 and a fourth motor 5222. The gripping mechanism 51 is mounted on the fourth slide of the fourth linear module 5221, so that the fourth motor 5222 can drive the gripping mechanism 51 to move in the height direction Z.

[0069] Combination Fig.15 When it is necessary to perform a withstand voltage test on the inductor, the first driving mechanism 52 of the first transplanting unit 5 first drives the grabbing mechanism 51 to move to the carrier 322 to grab a corresponding number of inductors; then, the first driving mechanism 52 drives the grabbing mechanism 51 to move to the upper seat 41 of the withstand voltage test fixture 4, so that one inductor is located in a test position 4111, and at the same time, the shell of the inductor is respectively in contact with the first probe 4112 and the third probe 4114 in the test position 4111, the first pin of the inductor is in contact with the second probe 4113 in the test position 4111, and the second pin of the inductor is in contact with the fourth probe 4115 in the test position 4111, so that the withstand voltage test fixture 4 can perform a withstand voltage test on the inductor.

[0070] After the voltage test fixture 4 completes the voltage test on the inductor, the first driving mechanism 52 of the first transplanting unit 5 first drives the grasping mechanism 51 to move to the recycling box 43 of the voltage test fixture 4; then, when there is an inductor that fails the voltage test among the multiple inductors grasped, the grasping mechanism 51 throws the inductor that fails the voltage test into the recycling box 43, and at the same time, a proximity switch sensor 44 corresponding to the inductor that fails the voltage test detects whether the inductor that fails the voltage test is thrown into the recycling box 43 for recycling; then, the first driving mechanism 52 drives the grasping mechanism 51 to move to the first direct vibration unit 62 of the turntable loading device 104, so as to place the inductor that passes the voltage test on the first direct vibration unit 62.

[0071] When the type of the inductor changes (such as the central angle of the pin position between two different types of inductors differs by 90°), the upper seat 41 is rotated 180° so that the upper seat 41 switches from the first assembly position to the second assembly position. At this time, the shell of the inductor contacts the second probe 4113 and the fourth probe 4115 in the test position 4111 respectively, the first pin of the inductor contacts the first probe 4112, and the second pin of the inductor contacts the third probe 4114. It can be seen that through the structural design of the withstand voltage test fixture 4, the withstand voltage test fixture 4 can perform withstand voltage tests on more than two inductors at the same time, which effectively improves the test efficiency. When the type of the inductor to be tested changes, the withstand voltage test fixture 4 can be adapted to different types of inductors by changing the assembly relationship between the upper seat 41 and the base 42, thereby effectively expanding the compatibility of the withstand voltage test fixture 4. At the same time, the withstand voltage test fixture 4 can also effectively reduce the waiting time of the turntable loading device 104.

[0072] The turntable loading device 104 includes a turntable 61, a first straight vibration unit 62, a suction module 7 and a driving unit. The turntable 61 is rotatably mounted on the frame 101 around its own axis, and the axis of the turntable 61 is parallel to the height direction Z. There are multiple suction modules 7, and the multiple suction modules 7 are evenly distributed along the circumference of the turntable 61, and the multiple suction modules 7 are all mounted on the turntable 61. The frame 101 is provided with multiple processing stations on the circumference of the turntable 61, wherein the first straight vibration unit 62 is arranged on one of the multiple processing stations, and the first straight vibration unit 62 is used to transfer the inductors that have passed the withstand voltage test transferred by the first transfer unit 5 one by one to the position directly below the suction module 7 on the turntable 61, so that when the suction module 7 passes through the first straight vibration unit 62, it can grab a corresponding number of inductors on the first straight vibration unit 62. In addition, other processing stations are respectively provided with other devices, such as interlayer withstand voltage detection devices, visual detection devices, packaging devices, etc., so that when the inductor is transferred to different processing stations by the suction module 7, the devices in the processing station can perform corresponding processing on the inductor. The driving unit is installed on the frame 101, and the driving unit is used to drive the turntable 61 to rotate and drive the turntable 61 to move relative to the frame 101 in the height direction Z, so as to control the suction module 7 to take and place the inductor.

[0073] Reference Fig.16 and Fig.17 The suction module 7 includes a base 71, a suction unit 72, a limit stopper 73, a third elastic member 74, an adjustment hand wheel 75, a fixing bolt 76, a shaft sleeve 77 and a spring plunger 78. The base 71 is installed on the turntable 61 so that the suction module 7 moves with the turntable. A through hole is provided in the middle of the base 71, and the through hole passes through the base 71.

[0074] The suction unit 72 includes an air column 721 and a suction nozzle 722. The air column 721 extends along the axial direction of the through hole and penetrates the through hole of the base 71, so that the two ends of the air column 721 are respectively located outside the through hole. A gas flow channel is provided in the middle of the air column 721, and the suction nozzle 722 is installed on the first end of the air column 721. The suction nozzle 722 is provided with an air hole, and the air hole is connected to the gas flow channel. Preferably, the suction nozzle 722 is detachably connected to the air column 721, so that when the suction nozzle 722 is damaged, only the air nozzle can be replaced without replacing the entire suction unit 72. The stopper 73 is installed at the second end of the gas column 721, so that the base 71 is located between the suction nozzle 722 and the stopper 73. The stopper 73 is used to prevent the gas column 721 from being separated from the base 71 and to limit the downward movement limit position of the suction nozzle 722, that is, the stopper 73 has the function of limiting the maximum distance between the suction nozzle 722 and the base 71 in the axial direction of the gas column 721. In addition, the base 71 is provided with an arc groove 711 at one end close to the stopper 73, and the axial direction of the arc groove 711 is perpendicular to the axial direction of the gas column 721. The arc groove 711 is used to play a certain supporting and limiting role for the adjusting hand wheel 75.

[0075] The third elastic member 74 is used to force the suction nozzle 722 to move away from the base 71 in the axial direction of the gas column 721. Specifically, in the present embodiment, the third elastic member 74 adopts a third compression spring, which is sleeved on the gas column 721, and the two ends of the third compression spring are respectively in contact with the first limit portion 7211 on the gas column 721 and the base 71. Of course, if the first limit portion 7211 is not provided on the gas column 721, the third compression spring is in contact between the suction nozzle 722 and the base 71. In addition, in other embodiments, the third elastic member 74 may also adopt a tension spring, and when the third elastic member 74 adopts a tension spring, the two ends of the third elastic member 74 may be respectively connected to the limit stopper 73 and the base 71, or the two ends of the third elastic member 74 may also be respectively connected to the second end of the gas column 721 and the base 71. It can be seen that the structure and position setting of the third elastic member 74 can be adjusted and set accordingly according to design requirements, installation space and other conditions.

[0076] Combination Fig.18 and Fig.19The adjusting hand wheel 75 is rotatably mounted on the base 71 around its own rotation axis, wherein the rotation axis of the adjusting hand wheel 75 is perpendicular to the axial direction. The adjusting hand wheel 75 comprises an adjusting portion 751, a rotating portion 752 and an operating portion 753, wherein the rotating portion 752 is located between the adjusting portion 751 and the operating portion 753, and the adjusting portion 751, the rotating portion 752 and the operating portion 753 are preferably integrally formed. In addition, the rotating portion 752 and the operating portion 753 are preferably cylindrically arranged, and the axis of the rotating portion 752, the axis of the operating portion 753 and the rotation axis of the adjusting hand wheel 75 are collinearly arranged. The adjusting portion 751 and the rotating portion 752 are located in the arc groove 711 of the base 71, and at least one matching surface 7511 is formed on the peripheral wall of the adjusting portion 751, and the limit stopper 73 can be adjacent to one matching surface 7511 or the base 71, so that the adjusting hand wheel 75 can adjust the vertical distance between the limit stopper 73 and the rotation axis in the axial direction of the gas column 721 through the matching surface 7511 of the adjusting portion 751. Preferably, the matching surface 7511 is a plane, because setting the matching surface 7511 as a plane can better ensure the stability and reliability when the matching surface 7511 contacts the limit stopper 73. In addition, the number of mating surfaces 7511 is preferably two to six, and each mating surface 7511 has a maximum vertical distance H from the rotation axis of the adjusting hand wheel 75, wherein the maximum vertical distance H between each mating surface 7511 and the rotation axis of the adjusting hand wheel 75 is not equal, or, among the two to six mating surfaces 7511, the maximum vertical distance H between at least two mating surfaces 7511 and the rotation axis of the adjusting hand wheel 75 is not equal, that is, at least two maximum vertical distances H are not equal.

[0077] For example, in this embodiment, the adjustment portion 751 has four mating surfaces 7511, the limit stop block 73 is always in mating contact with any one of the four mating surfaces 7511, and the maximum vertical distance H between two mating surfaces 7511 among the four mating surfaces 7511 and the rotation axis of the adjustment hand wheel 75 is equal, that is, in this embodiment, the adjustment hand wheel 75 can adjust the vertical distance between the limit stop block 73 and the rotation axis in the axial direction of the air column 721 to three different distance values, so that the suction module 7 can be suitable for target materials of three different heights. It should be noted that, in other embodiments, if the maximum vertical distance H between each mating surface 7511 and the rotation axis of the adjusting hand wheel 75 is not equal, and the limit stop block 73 is always in mating contact with one of the two or more mating surfaces 7511, the number of switchable positions of the limit stop block 73 is equal to the number of mating surfaces 7511 on the adjusting portion 751. For example, when there are five mating surfaces 7511 on the adjusting portion 751, the limit stop block 73 has five switchable positions, that is, the suction module 7 can be suitable for target materials of five different heights.

[0078] The operating portion 753 is located outside the arc groove 711 of the base 71, and the operating portion 753 is used to provide a force application point for the staff to rotate the adjustment hand wheel 75. The fixing bolt 76 is used to fix the adjustment hand wheel 75 on the base 71, wherein the axis of the fixing bolt 76 is parallel to the rotation axis of the adjustment hand wheel 75. The shaft sleeve 77 is arranged between the adjustment hand wheel 75 and the fixing bolt 76, so that the fixing bolt 76 can fix the adjustment hand wheel 75 on the base 71 through the shaft sleeve 77, and at the same time, the adjustment hand wheel 75 does not need to operate the fixing bolt 76 during the rotation process, that is, the setting of the shaft sleeve 77 makes it unnecessary to tighten or loosen the fixing bolt 76 when the adjustment hand wheel 75 is rotated. Specifically, the adjusting handwheel 75 is sleeved on the shaft sleeve 77. The shaft sleeve 77 is provided with a second limiting portion 771 at one end near the nut of the fixing bolt 76. The setting of the second limiting portion 771 can effectively prevent the adjusting handwheel 75 from escaping from the shaft sleeve 77. When the fixing bolt 76 fixes the shaft sleeve 77 and the adjusting handwheel 75 on the base 71, the stud of the fixing bolt 76 passes through the shaft sleeve 77 and is threadedly connected with the base 71, so that the two ends of the shaft sleeve 77 are respectively adjacent to the base 71 and the nut of the fixing bolt 76, thereby preventing the shaft sleeve 77 from moving axially along the fixing bolt 76.

[0079] In addition, two or more limiting grooves 7531 are provided on the side of the operating portion 753 facing the base 71, and the two or more limiting grooves 7531 are distributed around the rotation axis of the adjusting hand wheel 75. The spring plunger 78 is installed on the base 71, and when the limiting block 73 contacts and cooperates with the matching surface 7511 of the adjusting portion 751, the positioning bead of the spring plunger 78 is engaged with one of the two or more limiting grooves 7531. Preferably, the number of the limiting grooves 7531 is equal to the number of the matching surfaces 7511 on the adjusting portion 751, so that no matter which matching surface 7511 of the adjusting portion 751 is contacted and cooperated with by the limiting block 73, the spring plunger 78 can always be engaged with one of the multiple limiting grooves 7531. In this embodiment, the number of the limiting grooves 7531 is four, and the four limiting grooves are evenly distributed around the rotation axis of the adjusting hand wheel 75. The arrangement of the spring plunger 78 enables the spring plunger 78 to limit the adjusting hand wheel 75 through the limiting groove 7531 on the operating portion 753 each time the adjusting hand wheel 75 is rotated, so as to prevent the adjusting hand wheel 75 from rotating in a non-adjusting state.

[0080] When designing the suction module 7, the adjusting portion 751 of the adjusting hand wheel 75 can be pre-matched according to the number of target materials of different heights that the suction module 7 needs to adapt and the height value of the target materials, so that each mating surface 7511 on the adjusting portion 751 can correspond to a target material of different heights. When the height value of the target material that the suction module 7 needs to absorb changes, the adjusting hand wheel 75 can be rotated to make a corresponding mating surface 7511 on the adjusting hand wheel 75 come into mating contact with the limit stop block 73 to adjust the vertical distance between the limit stop block 73 and the rotation axis in the axial direction of the air column 721. The limit stop block 73 adjusts the relative position of the suction nozzle 722 in the axial direction through the air column 721, so that the suction nozzle 722 can adapt to the height of the target material, thereby ensuring that the suction module 7 can reliably absorb the target material and avoid damage to the target material. By designing the structure of the suction module 7, when the height direction of the inductor changes, the position of the suction nozzle 722 can be adjusted by adjusting the hand wheel 75, so that there is no need to replace the suction nozzles 722 of the suction module 7 one by one, and the production efficiency and compatibility of the suction module 7 can be better improved. It should be noted that the inductor test packaging machine provided by the present invention can also be used for processing transformers. In summary, it can be seen that through the structural design of the inductor test packaging machine, the inductor test packaging machine has the advantages of high production efficiency and strong compatibility.

[0081] Inductor testing and packaging machine second embodiment

[0082] Reference Fig. 20 and Fig.21 , the difference between this embodiment and the first embodiment of the suction module lies in the matching mode between the limit stop block 82 and the base 81 and the adjusting hand wheel. Specifically, in this embodiment, the adjusting portion 831 of the adjusting hand wheel has a matching surface 8311, and the limit stop block 82 can be matched with the matching surface 8311 or with the base 81. Although in this embodiment, the adjusting portion 831 of the adjusting hand wheel has only one matching surface 8311, when the limit stop block 82 is matched with the base 81, in the axial direction of the air column 841, the vertical distance between the limit stop block 82 and the rotation axis of the adjusting hand wheel is H1, and when the limit stop block 82 is matched with the matching surface 8311 of the adjusting portion 831, in the axial direction of the air column 841, the vertical distance between the limit stop block 82 and the rotation axis of the adjusting hand wheel is equal to the maximum vertical distance H2 between the matching surface 8311 and the rotation axis of the adjusting hand wheel, and H2 is greater than H1. It can be seen that although the adjusting portion 831 of the adjusting handwheel has only one mating surface 8311, through the structural design of the adjusting handwheel, the limit stop block 82 can still have two switchable positions by rotating the adjusting handwheel, so that the suction module can suck target materials of two different heights.

[0083] Finally, it should be emphasized that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
