Technical Field

[0001] The utility model relates to the technical field of VCM motor detection, in particular to a new type of automatic testing machine for VCM motor bases. Background Art

[0002] There is a base of a new type of VCM motor as Figure 10 shown. It is provided with a chip and a capacitor inside, and four first pin feet 81 are provided below one side thereof, and two second pin feet 82 are symmetrically arranged obliquely on the top surface. The chip and the capacitor are respectively connected to two first pin feet, and the second pin feet 82 need to be welded with coils for conduction in the future.

[0003] Therefore, after the VCM motor base is produced, it is necessary to perform power-on detection on the first pin feet 81 and the second pin feet 82 to ensure its normal use. At present, there is no device for automatically detecting this new type of VCM motor base. Based on this, a new type of automatic testing machine for VCM motor bases is proposed. Content of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a new type of automatic testing machine for VCM motor bases to solve the problem that there is currently no device for automatically detecting this new type of VCM motor base.

[0005] To solve the above technical problems, the utility model provides the following technical solution: A new type of automatic testing machine for VCM motor bases, with a multiple of two first pin feet provided below one side of the VCM motor base, and two second pin feet symmetrically arranged obliquely on the top surface of the VCM motor base.

[0009] The detection mechanism includes a second adjustment component. The output end of the second adjustment component is fixedly installed with a cross plate. Several detection components are provided on the bottom surface of the cross plate. Each detection component includes a support base. The bottom surface of the support base is provided with a first support block and a second support block. The height position of the bottom surface of the first support block is lower than the height position of the bottom surface of the second support block. The height difference between the bottom surface of the first support block and the bottom surface of the second support block is adapted to the height difference between the first pin and the second pin. Several first probes are provided on the bottom surface of the first support block. Two second probes are symmetrically provided obliquely on the bottom surface of the second support block. When the support base is directly above the fixed plate, the first probe is directly opposite to the first pin, and the second probe is directly opposite to the second pin;

[0010] The good product discharging mechanism is used to take out the good products detected by the detection mechanism on the clamping and fixing mechanism on the turntable;

[0011] The defective product discharging mechanism is used to take out the defective products detected by the detection mechanism on the clamping and fixing mechanism on the turntable;

[0012] When the turntable rotates, the clamping and fixing mechanism sequentially passes through the feeding mechanism, the detection mechanism, the good product discharging mechanism and the defective product discharging mechanism.

[0013] Preferably, at least two tray loading and unloading mechanisms are further included. The tray loading and unloading mechanism includes two support frames. The feeding mechanism and the good product discharging mechanism are respectively located between the two support frames of a tray loading and unloading mechanism. A plurality of discharging trays filled with VCM motor bases are stacked vertically on one support frame of a tray loading and unloading mechanism. A plurality of empty discharging trays are stacked vertically on the other support frame of a tray loading and unloading mechanism. An opening not smaller than the size of the discharging tray is provided on the top surface of each support frame. A fixing component is provided at the opening on the top surface of each support frame. An electric slide rail is provided below between the two support frames of each tray loading and unloading mechanism. A slide plate for supporting and placing the discharging tray is provided on the electric slide rail. A lifting component for lifting the discharging tray away from the slide plate is provided below the slide plate. A clamping component for fixing the discharging tray is provided on the top surface of the slide plate.

There are two fixing components, symmetrically arranged on the top surface of the support frame. The fixing component includes a driving cylinder and a supporting plate. The output end of the driving cylinder is fixedly installed with the supporting plate. The supporting plate is L-shaped and includes a horizontally extending portion. The size of the horizontally extending portion is not larger than the size of the gap.

[0015] Preferably, a third pin is provided on one side below the VCM motor base near the first pin side. A third probe is provided on the bottom surface of the first support block.

[0016] Preferably, there are four clamping and fixing mechanisms, which are arranged equidistantly in a circumferential manner on the top surface of the turntable.

[0018] Preferably, the good product discharging mechanism further includes a second photographing unit for photographing the cavities of the empty feeding trays.

[0020] After the feeding mechanism transports the VCM motor bases to be tested to the clamping and fixing mechanisms on the turntable, the turntable is adjusted to rotate, so that the clamping and fixing mechanisms fixedly placing the VCM motor bases to be tested move to the detection mechanism, making the detection assembly face the VCM motor bases to be tested. By adjusting the second adjustment assembly, it drives the cross plate to move downward until the first probe contacts the first pin foot and the second probe contacts the second pin foot, and electricity is supplied to the first probe and the second probe. Each pair of the first probe and the first pin foot forms a circuit, thereby completing the automatic detection work of the new type of VCM motor base, that is, completing the detection of whether the chips and capacitors in the VCM motor base are normal, and at the same time avoiding the trouble of welding coils on the second pin feet of the defective VCM motor bases subsequently, and avoiding meaningless labor.

Specific embodiments

[0032] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments. However, the following embodiments are only the preferred embodiments of the present utility model, not all of them. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the present utility model.

[0033] As Figures 1-10 shown, the present utility model provides a new type of automatic testing machine for VCM motor bases. There are a multiple of two first pins 81 (four are taken here as an example) provided below one side of the VCM motor base, and two second pins 82 are symmetrically arranged obliquely on the top surface of the VCM motor base. The automatic testing machine includes a turntable 1, at least one clamping and fixing mechanism 2, a feeding mechanism 3, a detection mechanism 4, a non-defective product discharging mechanism 5 and a defective product discharging mechanism 6;

[0034] When the turntable 1 rotates (it can be driven by a motor to rotate), the clamping and fixing mechanism 2 sequentially passes through the feeding mechanism 3, the detection mechanism 4, the non-defective product discharging mechanism 5 and the defective product discharging mechanism 6, so that the feeding, detection, non-defective product discharging and defective product discharging of the VCM motor base to be tested can be sequentially and cyclically completed;

[0035] As Figure 3As shown in the figure, the clamping and fixing mechanism 2 is arranged on the turntable 1. Each clamping and fixing mechanism 2 includes a fixing plate 21 and a fixing structure fixed on the fixing plate 21 for fixing the VCM motor base. The fixing structure here includes a pressing plate 22 arranged on the fixing plate 21, a driving cylinder, and a pressing plate 23. After the VCM motor base to be detected is placed on the fixing plate 21, one side of the VCM motor base abuts against the side surface of the pressing plate 22, and the driving cylinder drives the pressing plate 23 to move until the VCM motor base is tightly fixed, which is convenient for the subsequent rotation of the clamping and fixing mechanism 2 on the turntable 1, and the VCM motor base will not move on the fixing plate 21, facilitating subsequent accurate detection and the feeding work of good and defective products;

[0036] As Figure 4 shown in the figure, the feeding mechanism 3 is used to transfer the VCM motor base to be detected to the clamping and fixing mechanism 2 on the turntable 1;

[0037] Specifically, the feeding mechanism 3 includes a first adjustment component 31 (which can be set as a three-axis manipulator here), a first support plate 32, and a feeding component 33. The output end of the first adjustment component 31 is fixedly connected to the first support plate 32, and a number of feeding components 33 are arranged on the first support plate 32. Each feeding component 33 can be an existing cylinder jaw structure (clamping the outer wall of the VCM motor base to fix it, which is an existing technology and will not be elaborated here), or a cylinder support jaw structure (pressing against the inner wall of the VCM motor base to fix it, which is an existing technology and will not be elaborated here). Here, the cylinder support jaw structure is adopted to avoid the cylinder jaw structure from possibly damaging the first pin 81 on the side of the VCM motor base;

[0038] As Figure 6 and Figure 7 shown in the figure, the detection mechanism 4 includes a second adjustment component 42 (set as a cylinder here), the output end of the second adjustment component 42 is fixedly installed with a cross plate 43, and a number of detection components 44 are arranged on the bottom surface of the cross plate 43. Each detection component 44 includes a support seat 441, a first support block 442 and a second support block 443 are arranged on the bottom surface of the support seat 441. The height position of the bottom surface of the first support block 442 is lower than the height position of the bottom surface of the second support block 443. The height difference between the bottom surface of the first support block 442 and the bottom surface of the second support block 443 is adapted to the height difference between the first pin 81 and the second pin 82. A number of first probes 444 are arranged on the bottom surface of the first support block 442, and two second probes 445 are symmetrically arranged obliquely on the bottom surface of the second support block 443. When the support seat 441 is located directly above the fixing plate 21, the first probe 444 is directly opposite to the first pin 81, and the second probe 445 is directly opposite to the second pin 82;

[0039] After the feeding mechanism 3 transfers the VCM motor base to be detected to the clamping and fixing mechanism 2 on the turntable 1, the turntable 1 is adjusted to rotate, so that the clamping and fixing mechanism 2 with the VCM motor base to be detected placed thereon moves to the detection mechanism 4, and the detection assembly 44 is aligned with the VCM motor base to be detected. By adjusting the second adjustment assembly 42, it drives the cross plate 43 to move downward until the first probe 444 contacts the first pin 81 and the second probe 445 contacts the second pin 82. Then, power is supplied to the first probe 444 and the second probe 445, and the first probe 444 and the first pin 81 form a loop in pairs, thus completing the automatic detection of the first pin 81 and the second pin 82 (the new VCM motor base), that is, completing the detection of whether the chips and capacitors in the VCM motor base are normal, and at the same time avoiding the trouble of welding coils on the second pin 82 of the defective VCM motor base in the follow-up, and avoiding meaningless labor;

[0040] And after the detection, the good and defective conditions of the VCM motor base are automatically recorded (the recording method is the existing program technology and will not be elaborated here). After the VCM motor base detected by the detection mechanism 4 is determined to be good or defective, the information obtained is sent to the third adjustment assembly 51 and the fourth adjustment assembly 61 to realize the separate discharging of the good and defective VCM motor bases after detection (the specific signal control for accurately grasping the good or defective products is a relatively mature technology and will not be elaborated here);

[0041] As Figure 8 shown, the good product discharging mechanism 5 is used to take out the good products on the clamping and fixing mechanism 2 on the turntable 1 that have passed the detection by the detection mechanism 4;

[0042] Specifically, the good product discharging mechanism 5 includes a third adjustment assembly 51 (which can be set as a three-axis manipulator here), a second support plate 52, and a first discharging assembly 53. The output end of the third adjustment assembly 51 is fixedly connected to the second support plate 52, and a number of first discharging assemblies 53 (the first discharging assembly 53 here also adopts a cylinder claw structure) are arranged on the second support plate 52;

[0043] When the VCM motor base on the turntable 1 that has passed the detection by the detection mechanism 4 moves to be opposite to the good product discharging mechanism 5, the third adjustment assembly 51 is adjusted to drive the second support plate 52 to move, and the second support plate 52 drives the first discharging assembly 53 to move, so as to automatically discharge the detected good product VCM motor base;

[0044] As Figure 9 shown, the defective product discharging mechanism 6 is used to take out the defective products on the clamping and fixing mechanism 2 on the turntable 1 that have passed the detection by the detection mechanism 4;

[0045] The specific defective product discharging mechanism 6 includes a fourth adjusting component 61 (which can be set as a three-axis manipulator here), a third support plate 62, and a second discharging component 63. The output end of the fourth adjusting component 61 is fixedly connected to the third support plate 62, and a second discharging component 63 is arranged on the third support plate 62 (the second discharging component 63 here also adopts a cylinder claw structure. Since there are fewer defective products, only one second discharging component 63 is set here to save equipment costs);

[0046] The defective product discharging mechanism 6 further includes a support table 64. A clamping component 96 for fixing the feeding tray 7 is arranged on the top surface of the support table 64. Since the quantity of defective products is not very large, it takes a long time to fill the empty feeding tray 7 with defective products. Therefore, there is no need to set a feeding tray loading and unloading mechanism 9 here, and the operator can observe and replace the feeding tray 7 regularly to reduce equipment costs;

[0047] When the detection mechanism 4 detects a defective VCM motor base, when the subsequent turntable 1 rotates to face the defective product discharging mechanism 6, the fourth adjusting component 61 is adjusted to drive the third support plate 62 to move, and the third support plate 62 drives the second discharging component 63 to move, so that the defective VCM motor base on the clamping and fixing mechanism 2 is transported to the empty feeding tray 7 on the support table 64, and the automatic discharging work of the detected qualified VCM motor base is carried out;

[0048] Here, it is described by taking the example that there are four clamping and fixing mechanisms 2, which are equidistantly arranged in a circumferential manner on the top surface of the turntable 1: By setting four clamping and fixing mechanisms 2, continuous and uninterrupted detection work can be realized, and the feeding mechanism 3, the detection mechanism 4, the qualified product discharging mechanism 5, and the defective product discharging mechanism 6 can work synchronously, reducing the waiting time and improving the detection efficiency.

[0049] As Figure 1 and Figure 5 shown, the automatic testing machine further includes at least two feeding tray loading and unloading mechanisms 9. The feeding tray loading and unloading mechanism 9 includes two support frames 91. The feeding mechanism 3 and the qualified product discharging mechanism 5 are respectively located between the two support frames 91 of a feeding tray loading and unloading mechanism 9. A number of feeding trays 7 filled with VCM motor bases are stacked up and down on one support frame 91 of a feeding tray loading and unloading mechanism 9, and a number of empty feeding trays 7 are stacked up and down on the other support frame 91 of a feeding tray loading and unloading mechanism 9. An opening not smaller than the size of the feeding tray 7 is opened on the top surface of each support frame 91, and a fixing component 92 is arranged on the top surface of each support frame 91 at the opening. An electric slide rail 93 (an existing structure) is arranged below between the two support frames 91 of each feeding tray loading and unloading mechanism 9. A sliding plate 94 for supporting and placing the feeding tray 7 is arranged on the electric slide rail 93. A jacking component 95 for lifting the feeding tray 7 away from the sliding plate 94 is arranged below the sliding plate 94, and a clamping component 96 for fixing the feeding tray 7 is arranged on the top surface of the sliding plate 94;

[0050] The lifting assembly 95 here includes a lifting cylinder and a top plate. The top plate movably penetrates through the top surface of the sliding plate 94. The size of the top plate is smaller than that of the material placing tray 7, which facilitates the subsequent lifting of the empty material placing tray 7 by the top plate to a position above the supporting plate, so that the fixing assembly 92 can fix the empty material placing tray 7. At the same time, while supporting the sliding plate 94, it is ensured that the top plate will not contact the supporting plate subsequently;

[0051] The stacked material placing trays 7 filled with VCM motor bases to be measured are placed by people directly above the opening of the support frame 91 in advance, and the fixing assembly 92 fixes the lowermost material placing tray 7, so that the entire stacked material placing trays 7 filled with VCM motor bases to be measured are stably located on the support frame 91;

[0052] Specifically, taking the feeding mechanism 3 located between the two support frames 91 of a tray loading and unloading mechanism 9 as an example to illustrate its working principle: When it is necessary to automatically take out the material placing tray 7 filled with VCM motor bases to be measured, the electric slide rail 93 is adjusted to drive the sliding plate 94 to move to a position directly below the stacked material placing trays 7 filled with VCM motor bases to be measured (i.e., directly below the opening of a support frame 91). The lifting assembly 95 is adjusted to drive the top plate to move upward by the lifting cylinder until the top plate contacts the bottom surface of the lowermost material placing tray 7 in the stacked material placing trays 7 filled with VCM motor bases to be measured. At this time, the fixing assembly 92 is adjusted to no longer fix the stacked material placing trays 7 filled with VCM motor bases to be measured. The lifting cylinder is adjusted to contract by a distance equal to the height of one material placing tray 7, so that the sliding plate 94 moves downward. Then the clamping assembly 96 is adjusted to fix the lowermost material placing tray 7 filled with VCM motor bases to be measured. After that, the fixing assembly 92 is adjusted to fix the stacked material placing trays 7 filled with VCM motor bases to be measured again (the second-to-lowest material placing tray 7 at this time). At this time, the electric slide rail 93 is adjusted to drive the sliding plate 94 to move back to its original position, which facilitates the subsequent feeding mechanism 3 to take and detect the material placing tray 7 filled with VCM motor bases;

[0053] When it is necessary to take another material placing tray 7 filled with VCM motor bases to be measured subsequently, the empty material placing tray 7 needs to be transferred to another support frame 91 first, and then the material placing tray 7 filled with VCM motor bases to be measured is taken. Specifically, the electric slide rail 93 is also adjusted to drive the sliding plate 94 to move to directly below the opening of another support frame 91. The clamping assembly 96 is adjusted to no longer clamp and fix the empty material placing tray 7. Then the lifting assembly 95 is adjusted to drive the top plate to move upward by the lifting cylinder, thereby driving the empty material placing tray 7 to move upward until the fixing assembly 92 on another support frame 91 fixes the empty material placing tray 7, that is, the automatic unloading work of the empty material placing tray 7 is completed. When subsequent detection is carried out, the electric slide rail 93 is adjusted to drive the sliding plate 94 to move to a position directly below the stacked material placing trays 7 filled with VCM motor bases to be measured and repeat the above actions, thus completing the uninterrupted automatic feeding work;

[0054] Similarly, when blanking the qualified VCM motor bases that have been inspected, the same structural principle as above is also used for automatic blanking work, which will not be elaborated here.

[0055] As Figure 1 and Figure 5 shown, the material of the material tray 7 is plastic, and there is a gap between the stacked material trays 7. There are two fixing components 92, which are symmetrically arranged on the top surface of the support frame 91. The fixing component 92 includes a driving cylinder and a supporting plate. The output end of the driving cylinder is fixedly installed with the supporting plate. The supporting plate is L-shaped and includes a horizontally extending portion. The size of the horizontally extending portion is not greater than the size of the gap, ensuring that the horizontally extending portion can enter the gap, so as to support the material tray 7 well;

[0056] By setting the fixing component 92 composed of the driving cylinder and the supporting plate to support the material tray 7 instead of clamping and fixing it. Since the material tray 7 is made of plastic, it effectively avoids the deformation of the material tray 7 caused by clamping and fixing, thereby reducing the situation that the cavity on the material tray 7 is deformed and cannot accurately and completely accommodate the VCM motor base.

[0057] As Figure 7 and Figure 10 shown, a third pin 83 is provided on one side below the VCM motor base near the first pin 81 for grounding to prevent the internal circuit of the VCM motor base from short-circuiting. A third probe 446 is provided on the bottom surface of the first support block 442 to detect the quality of the third pin 83.

[0058] As Figure 4 shown, the loading mechanism 3 further includes a first photographing unit 34 for photographing the VCM motor bases to be tested filled on the material tray 7;

[0059] After the material tray 7 filled with the VCM motor bases to be tested is fixed on the sliding plate 94, before the VCM motor bases to be tested are picked up by the loading component 33, they are photographed by the first photographing unit 34 to ensure that the first pins 81 of the VCM motor bases to be grabbed are oriented in the same direction. To avoid the situation that when the first pins 81 of the VCM motor bases to be tested on the grabbed material tray 7 are reversed, when they are placed on the clamping and fixing mechanism 2 and detected by the detection mechanism 4, they cannot contact and conduct electricity with the first probe 444 on the bottom surface of the first support block 442, thus unable to be detected well.

[0060] As Figure 8 shown, the qualified blanking mechanism 5 further includes a second photographing unit 54 for photographing the cavity of the empty material tray 7, which is used to photograph the cavity of the empty material tray 7 (for placing the VCM motor base);

[0061] Since the material feeding tray 7 is a plastic tray, it is prone to deformation after injection molding. Therefore, not every cavity of the material feeding tray 7 can completely accommodate a VCM motor base. When the deformation of the cavity is small, it cannot accommodate a VCM motor base at this time, so the VCM motor base will protrude from the cavity. When the material feeding trays 7 are stacked vertically, the upper material feeding tray 7 cannot be placed stably, so the material feeding tray 7 will tilt, and the VCM motor base may fall. By setting the second photographing unit 54, before the qualified VCM motor bases detected by grasping are placed in the empty material feeding tray 7 for collection, the cavity of the empty material feeding tray 7 is photographed. When a deformed cavity is photographed, the VCM motor base is placed by skipping this cavity, thus avoiding the above situation;

[0062] It should be noted that there is no need to set a photographing unit in the defective product discharging mechanism 6. Since they are defective products and there is no need to stack the material feeding trays 7 vertically, even if the defective VCM motor bases are placed in the deformed cavities, the situation that the stacked material feeding trays 7 tilt and the VCM motor bases fall will not occur. Even when the material feeding tray 7 is replaced and transported subsequently, since the defective VCM motor bases fall because they are not completely accommodated in the cavities, and since they are defective products, there will be no impact.

[0063] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
