Description

Technical Field

[0001] The present invention relates to the field of VCM detection machines, and in particular to a double-rotating disk fully automatic detection machine and a detection method thereof. Background Art

[0002] The VCM motor (Voice Coil Motor in Chinese) is named for its structure which is similar to the voice coil of a speaker. Its full name is voice coil linear motor. It is a special form of direct drive motor with the characteristics of simple structure, small size, fast response, high acceleration and high speed. Its structure is divided into two parts: voice coil and magnet. Its working principle is as follows: when a current-carrying conductor passes through a magnetic field, a force perpendicular to the magnetic field lines will be generated. The magnitude of this force depends on the length of the conductor passing through the magnetic field, the magnetic field and the magnitude of the DC current. The voice coil motor converts the actual current into linear thrust and torque, controls the stretching position of the spring sheet, and thus drives the module lens connected to it to move and deflect, so that the real image formed can fall on the sensor, thereby obtaining the image we want. The amount of movement and deflection is linearly related to the actual current passing through.

[0003] VCM motors need to be tested before shipment. The traditional testing method is to manually assemble the VCM motor and lens, and then semi-automatically test the VCM motor's related performance. The specific operation process is: manually place a VCM motor to be tested in the test fixture, then manually place the lens in the VCM motor, and then perform a power-on test through the VCM test device. After the test is completed, manually remove the lens and VCM motor, and according to the test results, put qualified products on the qualified tray and unqualified products on the NG tray to complete the power-on test of the VCM motor. This detection method has the disadvantages of low detection efficiency, poor detection consistency, high production cost, and easy to cause secondary damage, thereby increasing the probability of defective products flowing out, affecting production efficiency.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Summary of the invention

[0022] Step S3: The first inspection station and the second inspection station place a lens on the product in the loading fixture and perform a power-on inspection;

[0023] Step S4: After the detection is completed, the first detection station and the second detection station absorb the lens;

[0024] Step S5: The unloading chuck grasps and inspects the products that have completed step S4 in the first inspection station and the second inspection station, and puts the products into different unloading areas or defective product boxes according to the inspection results.

[0025] As a preferred solution, the method further comprises step S2', wherein step S2' is performed after step S2;

[0065] Please refer to Figures 1 to 18 As shown, it shows the specific structure of an embodiment of the present invention.

[0066] A double-turntable fully automatic testing machine includes a testing machine and an automatic loading system 100, an automatic testing system 200, and an automatic unloading system 300 arranged on the testing machine;

[0067] The automatic feeding system 100 comprises a feeding mechanism 110 and a feeding mechanism 120. The feeding mechanism 110 comprises a feeding bin 111. The feeding mechanism 120 comprises a feeding chuck 121 and a feeding chuck moving device for controlling the movement of the feeding chuck 121.

[0068] The automatic inspection system 200 has a first inspection station and a second inspection station, both of which are provided with a turntable 220 and a detection mechanism 210, and the detection mechanism 210 is installed on one side of the turntable 220; and a loading fixture 221 is installed on the turntable 220;

[0069] The automatic unloading system 300 has an unloading mechanism for unloading products; the unloading mechanism has an unloading chuck 310 and an unloading chuck moving device for controlling the movement of the unloading chuck 310;

[0070] During operation, the loading chuck 121 grabs the product (i.e., the product to be tested) from the feeding mechanism 110 and places it in the loading fixture 221 on the turntable 220. The first inspection station and the second inspection station inspect the corresponding products on the turntable 220. After the inspection is completed, the unloading chuck 310 grabs the product in the loading fixture 221 and places it (the product after inspection) in the corresponding good product area or defective product area according to the inspection results to complete the unloading.

[0071] Next, each system of the fully automatic testing machine of this embodiment is further described in detail:

[0072] 1. Reference Figures 3 to 7 The feeding mechanism 110 includes a tray splitting device, a loading pallet 122 and a loading pallet moving device for controlling the movement of the loading pallet 122; a tray group is placed in the loading bin 111, and the tray splitting device splits the tray group in the loading bin 111 and fixes the split trays on the loading pallet 122, and then the loading chuck 121 grabs the product on the loading pallet 122 and moves it to the first inspection station or the second inspection station.

[0073] To further supplement, the tray splitting device includes a splitting manipulator 112 disposed on the upper bin 111, and the splitting manipulator 112 is connected to a splitting drive device and a lifting drive device; preferably, the lifting drive device can be a lifting cylinder connected to the splitting manipulator 112 through a screw assembly;

[0074] During operation, the loading support plate 122 holds and positions the bottom tray at the lower side of the tray group, the splitting manipulator 112 extends to clamp the second layer of trays from the bottom, and the lifting drive device drives the splitting manipulator 112 to rise, thereby separating the bottom tray;

[0075] Next, the loading pallet 122 moving device moves the loading pallet 122 and the "bottommost tray" on the loading pallet 122 to the loading station, and the loading chuck moving device drives the loading chuck 121 to move above the loading pallet 122; then, the loading chuck 121 grabs the product on the tray and moves the product to the first inspection station or the second inspection station for inspection.

[0076] Preferably, the upper bin 111 is provided with an anti-foolproof block, and correspondingly, the material tray is provided with an anti-foolproof notch.

[0077] Preferably, the loading support plate 122 is in the shape of an I, with avoidance grooves formed on one pair of sides and positioning blocks 1220 for positioning the tray on the other pair of sides. Setting the loading support plate 122 in the shape of an I is conducive to reducing manufacturing materials, which has another benefit that will be described below.

[0078] Preferably, a clamping arm 1221 is provided on the loading support plate 122, and the clamping arm 1221 is connected to an elastic reset member; through the clamping arm 1221, the material tray in the loading support plate 122 is further clamped to improve the working stability.

[0079] For details, see Figure 5The loading chuck 121 is connected to a lifting cylinder, and the lifting cylinder drives the loading chuck 121 to move up and down so that the loading chuck 121 can grab and put down the product; the loading chuck 121 has a clamping cylinder and a loading jaw group 1210 driven and connected by the clamping cylinder, and the loading jaw group 1210 is at least two loading jaws arranged opposite to each other; the clamping cylinder controls the relative opening or closing of the loading jaws, thereby realizing the grabbing and putting down of the product.

[0080] Preferably, the clamping cylinders are provided with two or more, each of which is provided with a feeding clamping jaw group 1210, and each clamping cylinder can control the feeding clamping jaws on the clamping cylinder to open or close relatively. When there are two clamping cylinders, each time the feeding clamping jaw moving device drives the feeding clamping jaw 121 to move to grab products, two products can be grabbed at one time, and then placed in the first inspection station and the second inspection station respectively, thereby improving the feeding efficiency.

[0081] Preferably, the feeding chuck 121 is provided with an adjustment device 1211 for adjusting the clamping width between the two feeding jaws when the feeding jaws are relatively opened or closed, so as to adapt to the specifications of the product. Preferably, a position sensor is provided on the feeding chuck 121, which can measure the distance between the feeding jaw group 1210 and the product, further improving the accuracy, reliability and safety of the detection machine.

[0082] Here, it should be noted that: the feeding jaw group 1210 adopts a clamping method, which has the advantage of adjustable clamping width compared to the traditional method of magnetic suction and vacuum suction. When the product is changed, there is no need to remake the feeding chuck 121. It is only necessary to adjust the size of the jaws of the jaw group when opening / closing to make it adapt to the size of various products; of course, in actual applications, the traditional magnetic suction and vacuum suction clamping method may be adopted due to other considerations. For this embodiment, both methods can realize the main functions of the detection machine, but are not limited to this.

[0083] Preferably, an empty tray recovery mechanism 130 is also included (see Figure 5), after the workpieces on the tray (tray with products) are taken away by the loading mechanism 120, the loading pallet moving device continues to drive the loading pallet 122 and the empty tray positioned on the loading pallet 122 to move to the empty tray recovery mechanism 130, and the empty tray recovery mechanism 130 recovers the empty tray (tray with products taken away). Specifically, the empty tray recovery mechanism 130 includes an empty tray bin 131 for stacking empty trays; the empty tray bin 131 is provided with a tray support block 132 and a lifting cylinder 133; the lifting cylinder 133 lifts the empty tray on the loading pallet 122, and the tray support block 132 extends to support and clamp the empty tray. Here, it is necessary to further explain that: the lifting cylinder 133 is driven and connected to a lifting column, and when it is lifted upward, it just passes through the avoidance grooves on both sides of the above-mentioned "I"-shaped loading tray 122 to act on the empty tray to lift the empty tray; then, as mentioned above, the tray support block 132 extends out to support and clamp the empty tray, completing the recovery of the empty tray; then the loading tray 122 is reset to the feeding bin 111.

[0084] Preferably, the loading support plate 122 moving device includes a first slide rail, which is arranged at the lower side of the loading bin 111 and the empty material tray bin 131; the loading support plate 122 is slidably arranged on the first slide rail, so that the loading support plate 122 can reciprocate between the loading bin 111 and the empty material tray bin 131. This is an existing conventional design, please refer to the attached drawings, and will not be described in detail here.

[0085] 2. Reference Figures 12 to 16 The fully automatic inspection machine of this embodiment has a workbench, and the automatic loading system 100, the automatic inspection system 200, and the automatic unloading system 300 are all arranged on the workbench; the automatic unloading system 300 (the automatic unloading system 300 includes an unloading mechanism) has a handling robot arm 320 arranged on the workbench; the unloading chuck 310 is arranged on the handling robot arm 320 and moves with the handling robot arm 320; the handling robot arm 320 is also connected with a tray clamp 330 for grabbing an empty tray. At the same time, the automatic unloading system 300 is provided with a plurality of unloading areas distributed on the workbench. Preferably, each unloading area is provided with an unloading support plate 340 and an unloading bin 350. The unloading support plate 340 is used to position and place the empty tray. When the empty tray is filled with products, the unloading support plate 340 moves it to the unloading bin 350 and is collected by the unloading bin 350. Specifically: the workbench is provided with a first tray storage area, a second tray storage area, a defective product storage area, and a good product unloading area, and the transport robot arm 320 can move the unloading chuck 310 and the tray clamp 330 to the first tray storage area, the second tray storage area, the defective product storage area, and the good product unloading area.

[0086] The first tray storage area and the second tray storage area are used to store empty trays of larger specifications and empty trays of smaller specifications, respectively, that is, the first tray storage area and the second tray storage area are used to store trays of different specifications. Of course, those skilled in the art can easily think of setting up a third tray storage area and a fourth tray storage area. In this embodiment, there are two tray storage areas.

[0087] The tray clamp 330 moves to the first tray storage area or the second tray storage area as needed to grab an empty tray, and then places it in the corresponding unloading tray 340 .

[0088] Preferably, (see Fig.13 ) The defective product storage area and the good product unloading area are both arranged on the left side of the handling robot arm 320, and the first tray storage area and the second tray storage area are both arranged on the front side of the handling robot arm 320. The unloading bin 350 is arranged on the right side of the handling robot arm 320, thus shortening the movement distance of the handling robot arm 320 and improving the work efficiency; it should be added that in actual application, the defective product storage area is a defective product box, which has multiple defective product collection grids; the multiple defective product collection grids place products of the same defective type in the same grid, that is, the defective product storage area is distinguished by the defective product type.

[0089] Further reading Fig.14 The lower bin 350 includes a first vertical plate and a second vertical plate which are arranged opposite to each other. The first vertical plate and the second vertical plate form a receiving position for placing a material tray (here, an empty material tray after collecting full products); the first vertical plate and the second vertical plate are both provided with a clamping device 352; a lifting device 351 is also provided on the lower side of the receiving position, and the lifting device 351 includes a lifting cylinder (here, the lifting cylinder refers to the lifting cylinder installed on the lower bin 350, and the lifting cylinder 133 refers to the lifting cylinder installed on the upper bin The lifting cylinder 133 of the bin 110, the two are different) and the top column connected to the lifting cylinder drive, when the unloading pallet 340 (which carries the unloading tray full of collected products) moves to the accommodating position, the lifting cylinder drives the top column to lift the unloading tray on the unloading tray 340 to separate it from the unloading tray 340, and then the clamping device 352 on the unloading bin 350 clamps the unloading tray, and then the lifting cylinder drives the top column to reset, and then the unloading tray 340 is also reset, that is, it returns to the position of collecting and inspecting the products. Here, the unloading tray refers to the empty tray used for product unloading after it is full. It should be noted that it is different from the empty tray after the above-mentioned products have been grabbed.

[0090] Correspondingly, the unloading support plate 340 is provided with an avoidance hole 341 adapted to the top column (see Fig.14), the top column passes through the avoidance hole 341 to lift the lower material tray upward, and then the clamping device 352 on the lower material bin 350 clamps the lower material tray and is collected by the lower material bin 350.

[0091] In actual application, several good product unloading areas are provided on the workbench, and the front and rear spacings are arranged on the workbench; accordingly, each good product unloading area is provided with an unloading support plate 340 and an unloading bin 350; the different good product unloading areas are used to unload products with different quality inspection results, and the unloading chuck 310 puts products with the same quality inspection results into the same good product unloading area, which is conducive to the classification and collection of products. That is, the several good product unloading areas can be distinguished according to the product's inspection performance level, which is conducive to product classification and grading.

[0092] See specifically Fig.16 The blanking chuck 310 is connected to a lifting cylinder, and the lifting cylinder drives the blanking chuck 310 to move up and down; the blanking chuck 310 has a clamping cylinder and a blanking clamping claw group arranged on the clamping cylinder, and the clamping cylinder can drive the blanking clamping claw group to open or close. This is the existing technology and will not be described in detail here.

[0093] Preferably, there are more than two clamping cylinders, each of which has a material unloading clamping claw group, and each clamping cylinder can drive the material unloading clamping claw group on the clamping cylinder to open or close. Therefore, each time the handling robot arm 320 can move to the first inspection station and the second inspection station in turn to grab the product and then place it in the unloading area. From the arrangement relationship of each unloading area in the attached figure, it can be seen that such a design further improves the efficiency of the equipment.

[0094] Preferably, the blanking chuck 310 is connected with an adjusting device for adjusting the opening or closing width of the blanking jaw group. Here, the advantages of the blanking chuck 310 using clamping are roughly the same as the clamping method used by the above-mentioned loading chuck 121, so it will not be repeated here.

[0095] 3. Reference Figures 8 to 11 , the detection mechanism 210 also includes a product pressing and lens picking and placing module 211 and an energized probe module 212. The product pressing and lens picking and placing module 211 presses the product on the loading fixture 221 and places the lens, and the energized probe module 212 has an energized probe 2120 and uses the energized probe 2120 to perform power-on detection on the product. Specifically: it also has a fixture module (the loading fixture 221 is part of the fixture module); the product pressing and lens picking and placing module 211 is set on the first stand, and the energized probe module 212 is set on the second stand, that is, the product pressing and lens picking and placing module 211 and the energized probe module 212 work independently of each other, and have a certain ingenuity in spatial arrangement; wherein:

[0096] The product pressing and lens placing module 211 comprises a product pressing device 2110 and a lens placing device 2111 . When working, the product pressing and lens placing module 211 presses the product on the loading fixture 221 and places the lens, and the power-on probe module 212 uses the power-on probe 2120 to detect the power-on of the product.

[0097] See also Fig.10 Preferably, the product pressing device 2110 includes a product pressing cylinder and a pressing column connected to the product pressing cylinder, and the product pressing cylinder drives the pressing column to move up and down. Preferably, the lens picking and placing device 2111 includes a lens picking and placing cylinder and a lens arranged on the lens picking and placing cylinder; it should be supplemented here that the picking and placing of the lens is realized by setting a lens suction head, and the lens suction head is equipped with a pressing probe, and the pressing probe can detect the distance between the lens and the product to be tested, so as to further improve the accuracy of the work.

[0098] Preferably, a first slide is provided on the first platform so that the product holding and lens placement module 211 can move left and right relative to the first platform; a second slide is provided on the first platform so that the product holding and lens placement module 211 can move forward and backward relative to the first platform.

[0099] Preferably, the product pressing and lens placing module 211 is connected with an electron microscope 2112, and the electron microscope 2112 can move left and right and forward and backward relative to the first stand. The electron microscope 2112 is provided to make it easier to observe the product.

[0100] Preferably, see Fig.11 A third slide is provided on the second platform so that the powered probe module 212 can move left and right relative to the second platform; a fourth slide is provided on the second platform so that the powered probe module 212 can move up and down relative to the first platform.

[0102] Preferably, the powered probe 2120 is arranged on the front and rear cylinders through an adjustment block. Through the adjustment block, the powered probe 2120 can be arranged on the front and rear cylinders in a front-to-rear adjustment manner and a left-to-right adjustment manner.

[0103] Preferably, a plurality of loading jigs 221 are arranged at circumferential intervals along the outer periphery of the turntable 220, further improving the detection efficiency. It should be noted that the turntable 220 is rotatably connected to the workbench, and the turntable 220 rotates to move each loading jig 221 to the product pressing and lens placement module 211 and the power probe module 212 in turn to complete the detection.

[0104] Here, it should be added that: the detection mechanism 210 detects the product (generally a VCM product), including detecting parameters such as the tilt, XYZ movement, and response frequency of the VCM product under different power-on conditions, and then feeds back the detection results to the system.

Specifically, the code reading module has a scanning terminal for scanning the code (usually a QR code) on the product. Here, it can be described in detail that: the code reading module can read the QR code and determine whether the QR code is correct or not according to the reading situation. If it can be read correctly and belongs to the set QR code category, it is determined to be an OK product, and if it cannot be read or does not belong to the set QR code category after reading and identification, it is determined to be an NG product; when the result is OK, the detection machine sends the product to the characteristic detection station (the characteristic detection station refers to the station where the detection mechanism 210 detects the performance of the product) for detection. When the result is NG, the product does not enter the characteristic detection station or enters the characteristic detection station without detection, and the NG product will be placed in the defective product area later.

[0112] See also Fig.18 This embodiment also discloses a detection method of a double-turntable fully automatic detection machine, which is applied with the aforementioned double-turntable fully automatic detection machine, and includes the following steps:

[0113] Step S1: a tray group is placed in the upper material bin 111, and the feeding mechanism 110 splits the tray group, separates the bottom tray from the tray group, and fixes it on the feeding pallet, and the feeding pallet feeds the bottom tray to the detection station side;

[0114] Step S2: The loading chuck 121 of the loading mechanism 120 grabs the product on the bottom tray and loads it into the loading fixture 221 of the first inspection station and the second inspection station;

[0115] Step S3: The first inspection station and the second inspection station place a lens on the product in the loading fixture 221 and perform a power-on inspection;

[0116] Step S4: After the inspection is completed, the first inspection station and the second inspection station absorb the lens on the product;

[0117] Step S5: The unloading chuck 310 grabs and inspects the products that have completed step S4 in the first inspection station and the second inspection station, and places the products into different unloading areas (different unloading areas according to the performance level of the products) or defective product boxes (different defective product collection grids according to the defective types) according to the inspection results.

[0118] Furthermore, the method further comprises step S2', wherein step S2' is performed after step S2;

[0119] The automatic inspection machine is provided with a two-dimensional code reading module, and in step S2', the two-dimensional code on the product is read, and according to the reading situation, whether the two-dimensional code is correct or not is determined, and the product is determined to be an OK product or an NG product;

[0120] When the judgment result is an OK product, the OK product enters step S3,

[0121] When the judgment result is NG product, the unloading chuck 310 puts the NG product into the defective product area or the NG product enters the inspection station but is not inspected, and then the unloading is completed by the unloading chuck 310.

[0122] It should be noted that: since a QR code reading unit is set up, the QR code of each product is read after loading. Therefore, the detection information of the product entering the characteristic detection station is associated with the QR code information, which can be fed back and / or stored in the system (such as a database) to facilitate product information management.

[0123] The design focus of the present invention is that it mainly designs a double-turntable fully automatic inspection machine, which has a higher degree of automation than the traditional inspection machine. Due to the setting of the double turntable, the inspection efficiency of the inspection machine is also doubled;

[0124] Secondly, the specific design of the automatic loading system and the automatic unloading system enables the double-turntable fully automatic inspection machine to automatically split the material tray group for loading, and automatically stack the unloading trays into material tray groups when unloading, reducing the labor intensity of personnel and further improving the inspection efficiency; and the overall layout of each system on the fully automatic inspection machine is reasonable and ingenious, suitable for production applications.

[0125] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
