Description

Technical Field

[0001] The present invention relates to the technical field of testing equipment, and in particular to a trigger testing device and method with a calibration function. Background Art

[0002] As a medium for human-computer interaction, capacitive buttons are widely used in the 3C industry due to their high sensitivity, low power consumption, and no mechanical wear. There are many small capacitors distributed inside the capacitive button. When we detect a capacitive button, we need to couple these small capacitors. In this process, the correct alignment between the probe and the button under test is crucial to the function of the test. Misalignment of the probe may result in incomplete coverage of the active area or contact with the casing, thereby destroying the ground coupling path required for the test. However, due to the tolerance of the test fixture and the button under test itself, as well as the installation error when the product is placed, there is often a certain position deviation between the probe and the button under test. For this reason, this deviation needs to be detected before each product test to provide an adjustment basis for the six-axis adjustment mechanism.

[0003] The common detection method on the market today is to use three cameras to visually analyze the keys to be tested to locate the spatial position of the keys to be tested. This method is not only expensive, but the position deviation between the probe and the key is a cumulative deviation composed of the position deviation between the camera and the key plus the installation tolerance of the camera and the probe, which is an indirect positioning method with a large error.

[0032] A. Load the test piece onto the base plate;

[0033] B. The adjustment component drives the probe and the pressure sensor matrix to approach the object to be tested until the detection portion of the probe and the pressure sensor matrix abut against the area to be tested of the object to be tested;

[0034] C. The offset between the detection part and the area to be measured and the pressure value of the detection part are respectively calculated by the pressure sensor matrix and the first sensor, and the corresponding signals are sent to the central control part, and the central control part sends a signal to the adjustment component, and the adjustment component adjusts the position and angle of the probe to correct the offset and pressure difference between the detection part and the area to be measured.

[0035] According to some embodiments of the present invention, the pressure sensor matrix covers the entire probe.

[0036] According to some embodiments of the present invention, in step C, there is an offset A between the detection unit and the area to be detected in the X-axis direction.

[0037] When the offset A appears on the left side, the adjustment component drives the probe to translate to the right by a distance A;

[0038] When the offset A appears on the right side, the adjustment component drives the probe to translate a distance A to the left.

[0039] According to some embodiments of the present invention, in step C, there is an offset B between the detection unit and the area to be detected in the Y-axis direction.

[0040] When the offset B appears on the upper side, the adjustment component drives the probe to translate downward by a distance B;

[0041] When the offset B appears at the lower side, the adjustment component drives the probe to translate upward by a distance B.

[0042] According to some embodiments of the present invention, in step C, there is no offset between the detection portion and the area to be detected, and when the pressure value of the first sensor does not match the preset pressure value, when

[0043] If the value of the first sensor is too large, the six-axis adjustment drive assembly drives the probe to retreat backwards;

[0044] The value of the first sensor is too small, and the six-axis adjustment drive assembly drives the probe forward.

[0045] According to some embodiments of the present invention, in step C, when there is an offset between the detection portion and the area to be detected on both the upper and lower sides, or when the offset of one side appears on the other side after being adjusted up and down in the Y-axis direction, the adjustment component drives the probe to rotate θ1 degrees clockwise around the X-axis. If the offset increases, the probe is rotated 2θ1 degrees counterclockwise around the X-axis.

[0047] Wherein, C is the width value of the detection unit, and D is the width value of the area to be detected detected by the detection unit.

[0048] According to some embodiments of the present invention, in step C, when there is an offset between the detection portion and the area to be detected on both the left and right sides, or when the offset of one side appears on the other side after being adjusted up and down in the X-axis direction, the adjustment component drives the probe to rotate θ2 degrees clockwise around the Y axis.

[0052] When the gap is smaller on the left and larger on the right, the probe is driven to rotate θ3 degrees clockwise around the Z axis;

[0053] When the gap is smaller on the left and larger on the right, the probe is driven to rotate θ3 degrees counterclockwise around the Z axis.

[0054] Wherein, θ3 is the angle between the detection part and the area to be detected.

[0055] According to some embodiments of the present invention, step C further includes the following steps:

[0056] S1. Determine whether there is an upper gap between the detection portion and the area to be tested. If there is an upper gap, the adjustment component drives the probe to move downward, and then enters S3. If there is no upper gap, enter S2;

[0057] S2. Determine whether there is a gap below the detection portion and the area to be tested. If there is a gap below the detection portion, the adjustment component drives the probe to move upward and drives the probe to press the test piece. If there is no gap below the detection portion, enter S3;

[0058] S3. Determine whether there is a left gap between the detection portion and the test area. If there is a left gap, the adjustment component drives the probe to move to the right and drives the probe to press the test piece, and then enters S5. If there is no left gap, enter S4;

[0059] S4. Determine whether there is a right gap between the detection unit and the test area. If there is a right gap, the adjustment component drives the probe to move to the left and drives the probe to press the test piece. If there is no right gap, enter S5;

[0060] S5. Determine whether there is an angle θ3 between the detection part and the area to be tested. If there is, the adjustment component drives the probe to rotate θ3 degrees around the Z axis and returns to step S1. If there is no angle θ3, enter S6.

[0061] Wherein, θ3 is the angle between the detection part and the area to be detected;

[0062] S6. Determine the size between the width value C of the detection unit and the width value D of the area to be detected by the detection unit. If D<C, the adjustment component drives the probe to rotate θ1 degrees around the Y axis and returns to step S1. If D<C is not satisfied, enter S7.

[0063]

[0064] Wherein, C is the width value of the detection unit, and D is the width value of the area to be detected detected by the detection unit;

[0065] S7. Determine the difference between the length value E of the detection unit and the length value F of the area to be tested detected by the detection unit.

The DUT is loaded onto the base plate by installing the module, and the pressure sensor matrix on the probe is used to contact the DUT area of ​​the DUT to determine the position offset, angle offset and pressure difference between the DUT area and the detection part of the probe. The displacement and angle of the probe are adjusted by adjusting the components to correct the offset and gap between the detection part and the DUT area, while meeting the preset pressure value to improve the overall test accuracy.

The terms used in this specification are only for describing specific embodiments and are not intended to limit the present invention.

[0095] Reference Figures 1 to 4The technical solution of the first aspect of the present invention relates to a trigger test device with a calibration function, comprising: a base plate 100; an installation module comprising a carrier assembly 200 and a clamping assembly 300, the carrier assembly 200 is arranged on the base plate 100, and the carrier assembly 200 is used to position and load the test piece 600; the clamping assembly 300 is arranged on the base, and the carrier assembly 200 is used to clamp and fix the test piece 600; a detection assembly 400, including a probe 420 arranged along the Z-axis direction and a pressure sensor matrix 440, the pressure sensor matrix 440 is arranged on the probe 420 and covers the detection part 421 of the probe 420, it should be noted that the probe The detection part 421 of the head 420 is consistent in shape with the area to be tested of the test piece 600, and the area of ​​the pressure sensor matrix 440 is larger than the detection part 421, that is, it can cover the entire detection part 421. An offset is generated between the two, which is also within the range of the pressure sensor matrix 440. The pressure sensor matrix 440 is used to detect the offset between the detection part 421 and the area to be tested, and can also detect the pressure value; the adjustment component 500 is arranged on the base along the Z-axis direction, and the first sensor is arranged on the adjustment component 500. The adjustment component is used to adjust the position of the probe 420 and correct the offset between the detection part 421 and the area to be tested.

[0096] It should be noted that the pressure sensor matrix 440 refers to at least two pressure sensors distributed in the X-axis and Y-axis directions. In the present embodiment, the pressure sensor matrix 440 is in the form of a thin film.

[0097] The testing principle is as follows: the probe 420 is driven to move forward by the adjusting component 500, that is, to move in the positive direction of the Z axis, until the detection part 421 of the probe 420 contacts the test area of ​​the test piece 600, and the contact surface generates pressure on the pressure sensor matrix 440. The pressure sensor matrix 440 sends the received pressure image signal to the central control system. The central control system compares the compressed image with the original image area of ​​the detection part 421 to determine whether the detection part 421 is aligned with the test area, or whether an offset or deflection occurs, and thus sends a corresponding signal to the adjusting component 500. The position of the probe 420 is adjusted by the adjusting component 500, and finally the offset and deflection between the detection part 421 of the probe 420 and the test area of ​​the test piece 600 are corrected. The two are aligned and tested to improve the test accuracy.

[0098] It should be noted that in the context of this embodiment, up refers to the positive direction of the Y axis, down refers to the negative direction of the Y axis, left refers to the negative direction of the X axis, right refers to the positive direction of the X axis, front refers to the positive direction of the Z axis, and back refers to the negative direction of the Z axis.

[0099] According to some embodiments of the present invention, the detection component 400 also includes a floating mounting plate 450, which is connected to the first sensor 410 via a plurality of elastic members or equal-height bolts 460, and the probe 420 is connected to the floating mounting plate 450. The first sensor 410 and the probe 420 are connected via the floating mounting plate 450 to ensure that the pressure on the probe 420 can be accurately measured while avoiding damage to the first sensor 410 due to rigid contact, thereby ensuring the service life of the first sensor 410 and the probe 420.

[0100] According to some embodiments of the present invention, a mounting frame 430 is further included. The mounting frame 430 is connected to the probe 420 . The mounting frame 430 is provided with an avoidance hole 431 for avoiding the detection part 421 . The pressure sensor matrix 440 is arranged on the mounting frame 430 and contacts and covers the detection part 421 .

[0101] According to some embodiments of the present invention, referring to Figure 4 The adjustment component 500 includes: a Y-axis rotation adjustment motor 510, which is arranged in sequence along the Z-axis direction, and is arranged on the base; an X-axis rotation adjustment motor 520, which is arranged on the Y-axis rotation adjustment motor 510; a Y-axis translation adjustment motor 530, which is arranged on the X-axis rotation adjustment motor 520; an X-axis translation adjustment motor 540, which is arranged on the Y-axis translation adjustment motor 530; a Z-axis translation adjustment motor 550, which is arranged on the X-axis translation adjustment motor 540; a Z-axis rotation adjustment motor 560, which is arranged on the Z-axis translation adjustment motor 550, and a first sensor 410 is arranged on the Z-axis rotation adjustment motor 560, by Figure 4 It can be seen that the Y-axis rotation adjustment motor 510 and the X-axis rotation adjustment motor 520 are arranged at the rear, and the two are connected to the Y-axis translation adjustment motor 530 through a connecting plate or a connecting frame, and the X-axis translation adjustment motor is installed on the Y-axis translation adjustment motor 530 through a connecting plate or a connecting frame, and the Z-axis translation adjustment 550 is installed on the X-axis translation adjustment motor, and the Z-axis rotation adjustment motor 560 is connected to the Z-axis translation adjustment motor 550 through a connecting plate. From back to front, the probe 420 can be driven to rotate around the Y-axis, rotate around the X-axis, translate along the Y-axis, translate along the X-axis, translate along the Z-axis, and rotate around the Z-axis in sequence. By separating the adjustment of the 6 axes and adjusting them separately, the offset and offset angle in each direction can be adjusted independently, and the adjustment accuracy is higher. A single offset or offset angle can be adjusted without affecting the position and angle in other directions.

[0102] In the above embodiment, the X-axis translation adjustment motor 540, the Y-axis translation adjustment motor 530 and the Z-axis translation adjustment motor 550 are all configured as screw-nut motors, which have high precision and can self-lock at any time after rotation, thereby facilitating the adjustment and maintenance of test accuracy.

All components in this embodiment are arranged in an outer frame shell, and the push plate 210 can slide out of the outer frame shell, that is, the front side of the area where the base plate 100 is located, so that the workpiece to be tested can be prevented from being in the positioning carrier 220 or the workpiece that has been tested can be taken out, and the push plate 210 can be pushed backward into the outer frame shell for testing; a wireless charging base 230, which is arranged on the push plate 210 and is used to supply power to the workpiece to be tested 600; a positioning carrier 220, which is arranged on the wireless charging base 230 and is used to load and position the workpiece to be tested 600.

[0104] According to some embodiments of the present invention, a support frame 110 is further provided on the base plate 100, and the mounting module further includes a clamping assembly 300, which includes: a first cylinder 320, which is provided on the support frame 110 along the Y-axis direction; a first pressure block 310, which is connected to the output end of the first cylinder 320, and the first pressure block 310 is used to fix the workpiece to be tested 600 in the Y-axis direction, and the first pressure block 310 is driven by the first cylinder 320 to move downward, that is, to move in the negative direction of the Y-axis, until the first pressure block 310 abuts against the workpiece to be tested 600, thereby limiting the displacement of the workpiece to be tested 600 in the Y-axis direction; two second cylinders 340, It is arranged on the bottom plate 100 along the X-axis direction and is arranged on both sides of the push plate 210; the two second pressure blocks 330 are respectively connected to the output ends of the two second cylinders 340, and the two second pressure blocks 330 are used to clamp and fix the push plate 210 in the X-axis direction.

[0105] According to some embodiments of the present invention, a guide rail 120 is provided on the base plate 100 along the Z-axis direction, and the push plate 210 is slidably connected to the guide rail 120. The push plate 210 is provided with a push-pull member 211, which is used to drive the push plate 210 to enter or move away from the area of ​​the base plate 100.

[0106] A testing method according to the technical solution of the second aspect of the present invention is applied to any of the above trigger testing devices with calibration function, comprising the following steps:

[0107] A. Load the test piece 600 onto the base plate 100;

[0108] B. The adjustment component 500 drives the probe 420 and the pressure sensor matrix 440 to approach the object to be tested 600 until the detection portion 421 of the probe 420 and the pressure sensor matrix 440 abut against the test area of ​​the object to be tested 600;

[0109] C. The offset between the detection part 421 and the area to be measured and the pressure value of the detection part 421 are calculated through the pressure sensor matrix 440, and the corresponding signal is sent to the central control part, which sends a signal to the adjustment component 500. The adjustment component 500 adjusts the position and angle of the probe 420 to correct the offset and pressure difference between the detection part 421 and the area to be measured.

[0110] According to some embodiments of the present invention, in the above step B, the pressure sensor matrix 440 covers the entire probe 420. By covering the entire probe 420 with the pressure sensor matrix 440, the force distribution pattern can be obtained more accurately, making the correction adjustment after measurement more accurate.

[0111] According to some embodiments of the present invention, referring to Figure 5 In step C, there is an offset A between the detection part 421 and the detection area in the X-axis direction.

[0112] When the offset A appears on the left side, the adjustment assembly 500 drives the probe 420 to translate to the right by a distance A;

[0113] When the offset A appears on the right side, the adjustment assembly 500 drives the probe 420 to translate a distance A to the left.

[0114] According to some embodiments of the present invention, referring to Figure 6 In step C, there is an offset B between the detection unit 421 and the detection area in the Y-axis direction.

[0115] When the offset B appears on the upper side, the adjustment assembly 500 drives the probe 420 to translate downward by a distance B;

[0116] When the offset B appears at the lower side, the adjustment assembly 500 drives the probe 420 to translate a distance B upward.

[0117] It can be understood that when the detection part 421 and the area to be tested have an offset in the X-axis direction or an offset in the Y-axis direction, the deviation correction can be completed by driving the probe to move in the opposite direction of the offset along the X-axis through the X-axis translation adjustment motor 540, or by adjusting the Y-axis translation adjustment motor 530 to move the offset in the opposite direction along the Y-axis. Figure 5As shown, the offset A refers to the area where the detection part 421 and the area to be measured cannot overlap in the X-axis direction, that is, in the left and right directions. The value of this area in the X-axis direction is A. During the measurement process, after the pressure sensor matrix 440 is attached to the area to be measured, the area where the pressure sensor matrix 440 covering the entire probe 420 is squeezed forms a graph of the area to be measured. By comparing this graph with the graph of the detection part 421, a shape distribution diagram of the actual position of the area to be measured and the detection part 421 is obtained, thereby obtaining the offset A or offset B, as shown in FIG. Figure 5 and Figure 6 As shown, other offsets and offset angles in the following text are obtained by comparison in the same way.

[0118] According to some embodiments of the present invention, in step C, there is no offset between the detection portion 421 and the area to be detected, and the pressure value of the first sensor 410 does not match the preset pressure value.

[0119] The value of the first sensor 410 is too large, and the six-axis adjustment drive assembly drives the probe 420 to retreat backwards;

[0120] The value of the first sensor 410 is too small, and the six-axis adjustment drive assembly drives the probe 420 forward.

[0121] According to some embodiments of the present invention, referring to Figure 7 In step C, when there is an offset between the detection part 421 and the area to be detected on both the upper and lower sides, or when the offset of one side appears on the other side after the Y-axis is adjusted up and down, the adjustment component drives the probe 420 to rotate θ1 degrees clockwise around the X-axis. If the offset increases, it rotates 2θ1 degrees counterclockwise around the X-axis.

[0122]

[0123] Wherein, C is the width value of the detection unit 421 , and D is the width value of the area to be detected detected by the detection unit 421 .

[0124] According to some embodiments of the present invention, referring to Figure 8 In step C, when the detection part 421 and the area to be detected have an offset on both the left and right sides, or when the offset of one side appears on the other side after the up-down adjustment in the X-axis direction, the adjustment component drives the probe 420 to rotate θ2 degrees clockwise around the Y-axis. If the offset increases, the probe 420 rotates 2θ2 degrees counterclockwise around the Y-axis.

[0125]

[0126] Wherein, E is the length value of the detection unit 421 , and F is the length value of the area to be detected detected by the detection unit 421 .

[0127] It is understandable that when the width of the detection portion 421 and the area to be detected are different, and the detection portion 421 and the area to be detected are offset in the up and down directions, such as Figure 7 As shown, when the probe 420 is in contact with the area to be tested, the squeezed part of the pressure sensor matrix 440 forms a graph. After comparing the graph with the graph of the detection part 421, there are detection blank areas in both the upper and lower directions, and only a pressure signal image is formed in the middle. At the same time, its left and right width values ​​are consistent with the width value of the area to be tested, which means that the detection part 421 and the area to be tested have an angle of deviation on the X axis; when the left and right width values ​​of the detection part 421 and the area to be tested are different, and the detection part 421 and the area to be tested have an offset in the left and right directions, as shown in FIG. Figure 8 As shown, there are detection blank areas in both the left and right directions of the image generated by the pressure sensor matrix 440 and the image of the detection unit 421, and only a pressure signal image is formed in the middle. At the same time, the width value in the up and down directions is consistent with the width value of the area to be measured, which means that the detection unit 421 and the area to be measured have a certain deviation angle on the Y axis. After the deviation angle is calculated by the above formula, the X-axis rotation adjustment motor 520 or the Y-axis rotation adjustment motor 510 drives the probe to rotate along the X-axis or the Y-axis to rotate the above angle to complete the deviation correction.

[0128] According to some embodiments of the present invention, referring to Fig. 9 In step C, when the offset gap appears in the upper left and lower right, the lower left and upper right, or appears in one corner and then appears in the other corner after adjustment in the X-axis and Y-axis directions, and the left and right sizes are uneven, the adjustment component drives the probe 420 to rotate around the Z-axis direction.

[0129] When the gap is smaller on the left and larger on the right, the probe 420 is driven to rotate θ3 degrees clockwise around the Z axis;

[0130] When the gap is smaller on the left and larger on the right, the probe 420 is driven to rotate θ3 degrees counterclockwise around the Z axis.

[0131] Wherein, θ3 is the angle between the detection part 421 and the area to be detected.

[0132] According to some embodiments of the present invention, referring to Fig.10 , step C also includes the following steps:

[0133] S1. Determine whether there is an upper gap between the detection portion and the area to be tested. If there is an upper gap, the adjustment component drives the probe to move downward, and then enters S3. If there is no upper gap, enter S2;

[0134] S2. Determine whether there is a gap below the detection portion and the area to be tested. If there is a gap below the detection portion, the adjustment component drives the probe to move upward and drives the probe to press the test piece. If there is no gap below the detection portion, enter S3;

[0135] S3. Determine whether there is a left gap between the detection portion and the test area. If there is a left gap, the adjustment component drives the probe to move to the right and drives the probe to press the test piece, and then enters S5. If there is no left gap, enter S4;

[0136] S4. Determine whether there is a right gap between the detection unit and the test area. If there is a right gap, the adjustment component drives the probe to move to the left and drives the probe to press the test piece. If there is no right gap, enter S5;

[0137] S5. Determine whether there is an angle θ3 between the detection part and the area to be tested. If there is, the adjustment component drives the probe to rotate θ3 degrees around the Z axis and returns to step S1. If there is no angle θ3, enter S6.

[0138] Wherein, θ3 is the angle between the detection part and the area to be detected;

[0139] S6. Determine the size between the width value C of the detection unit and the width value D of the area to be detected by the detection unit. If D<C, the adjustment component drives the probe to rotate θ1 degrees around the Y axis and returns to step S1. If D<C is not satisfied, enter S7.

[0140]

[0141] Wherein, C is the width value of the detection unit, and D is the width value of the area to be detected detected by the detection unit;

[0142] S7. Determine the difference between the length value E of the detection unit and the length value F of the area to be tested detected by the detection unit. If F<E, the adjustment component drives the probe to rotate θ2 degrees around the X-axis and returns to step S1. If F<E is not satisfied, enter S8.

[0143]

[0144] Wherein, E is the length value of the detection unit, and F is the length value of the area to be detected detected by the detection unit;

[0145] S8. The adjusting component drives the probe to move along the Z-axis direction until the value on the first sensor is the same as the preset pressure value.

[0146] Through the entire process from S1 to S8 above, the offset and deflection between the detection part 421 of the probe 420 and the area to be measured can be fully corrected and modified, thereby ensuring that the detection part 421 is completely attached to the area to be measured to ensure the measurement accuracy.

[0147] The beneficial effects of the present invention are as follows.

[0148] 1. The test piece 600 is loaded by the carrier assembly 200, and the test piece 600 is clamped and fixed by the clamping assembly 300. The test area of ​​the test piece 600 is covered by the pressure sensor matrix 440 on the probe 420, thereby determining the position offset and angle offset between the test area and the detection part 421 of the probe 420 on the X-axis, Y-axis and Z-axis. At the same time, the first sensor 410 is used to determine the pressure value of the detection part 421 and compare it with the preset pressure value. The displacement and angle of the probe 420 are adjusted by the adjustment assembly 500, thereby correcting the offset and gap between the detection part 421 and the test area, while meeting the preset pressure value, and improving the overall test accuracy.

[0149] 2. The first pressing block 310 presses the test piece 600 in the Y-axis direction, and the two second pressing blocks 330 lock the push plate 210 in the X-axis direction, thereby improving the stability of the test piece 600 during testing.
