Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a trigger testing device. Background Technology

[0002] Capacitive buttons, as a medium for human-computer interaction, are widely used in the 3C industry due to their advantages such as high sensitivity, low power consumption, and no mechanical wear. Numerous small capacitors are distributed inside a capacitive button, and these capacitors need to be coupled when testing a capacitive button. In this process, the correct alignment between the probe and the button under test is crucial to the functionality of the test. Misalignment of the probe may result in incomplete coverage of the active area or contact with the casing, thus disrupting the grounding coupling path required for the test. However, due to the tolerances of the test fixture and the button itself, as well as installation errors during product placement, there is often a certain positional deviation between the probe and the button under test. Therefore, this deviation needs to be checked before testing each product to provide an adjustment basis for the six-axis adjustment mechanism.

[0003] Currently, the common testing method on the market is to use three cameras to visually analyze the button under test to locate its spatial position. This method is not only expensive, but the positional deviation between the probe and the button is a cumulative deviation consisting of the positional deviation between the camera and the button when taking pictures and the installation tolerance between the camera and the probe. This is an indirect positioning method, which inherently has a large error. Utility Model Content

[0055] Reference Figures 1 to 4 The first aspect of this utility model relates to a trigger testing device with calibration function, comprising: a base plate 100; a mounting module including a carrier plate assembly 200 and a clamping assembly 300, the carrier plate assembly 200 being disposed on the base plate 100 and used for positioning and loading a test piece 600; a clamping assembly 300 being disposed on the base, the carrier plate assembly 200 being used for clamping and fixing the test piece 600; and a detection assembly 400 including a probe 420 disposed along the Z-axis and a pressure sensor matrix 440, the pressure sensor matrix 440 being disposed on the probe 420 and covering the detection part 421 of the probe 420. It should be noted that... The probe 420's detection part 421 has the same shape as the test area of ​​the test piece 600, while the area of ​​the pressure sensor matrix 440 is larger than the detection part 421, meaning it can cover the entire detection part 421. Any offset between the two 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 test area, and can also detect the pressure value. The adjustment component 500 is set on the base along the Z-axis direction, and the first sensor is set 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 test area.

[0056] It should be noted that the pressure sensor matrix 440 refers to the distribution of at least two pressure sensors in both the X-axis and Y-axis directions. In this embodiment, the pressure sensor matrix 440 is in the form of a thin film.

[0057] The testing principle is as follows: The probe 420 is driven to move forward by the adjustment component 500, that is, in the positive Z-axis direction, until the detection part 421 of the probe 420 contacts the test area of ​​the test piece 600. 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 image of the pressure received 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 there is any offset or angle. The corresponding signal is sent to the adjustment component 500 to adjust the position of the probe 420. Finally, the offset and angle between the detection part 421 of the probe 420 and the test area of ​​the test piece 600 are corrected. After the two are aligned, the test is performed to improve the test accuracy.

[0058] It should be noted that, in the context of this embodiment, "up" refers to the positive Y-axis direction, "down" refers to the negative Y-axis direction, "left" refers to the negative X-axis direction, "right" refers to the positive X-axis direction, "front" refers to the positive Z-axis direction, and "back" refers to the negative Z-axis direction.

[0059] According to some embodiments of the present invention, the detection assembly 400 further includes a floating mounting plate 450. The floating mounting plate is connected to the first sensor 410 by multiple elastic elements or equal-height bolts 460. The probe 420 is connected to the floating mounting plate 450. The floating mounting plate 450 connects the first sensor 410 and the probe 420 to ensure that the pressure on the probe 420 can be accurately measured while avoiding rigid contact damage to the first sensor 410, thus ensuring the service life of the first sensor 410 and the probe 420.

[0060] According to some embodiments of the present invention, it also includes a mounting bracket 430, which is connected to the probe 420. The mounting bracket 430 is provided with a clearance hole 431 for avoiding the detection part 421. The pressure sensor matrix 440 is disposed on the mounting bracket 430 and contacts and covers the detection part 421.

[0061] According to some embodiments of this utility model, refer to Figure 4The adjustment assembly 500 includes, sequentially arranged along the Z-axis: a Y-axis rotary adjustment motor 510, mounted on the base; an X-axis rotary adjustment motor 520, mounted on the Y-axis rotary adjustment motor 510; a Y-axis translation adjustment motor 530, mounted on the X-axis rotary adjustment motor 520; an X-axis translation adjustment motor 540, mounted on the Y-axis translation adjustment motor 530; a Z-axis translation adjustment motor 550, mounted on the X-axis translation adjustment motor 540; and a Z-axis rotary adjustment motor 560, mounted on the Z-axis translation adjustment motor 550. A first sensor 410 is mounted on the Z-axis rotary adjustment motor 560. Figure 4 As can be seen, the Y-axis rotary adjustment motor 510 and the X-axis rotary adjustment motor 520 are located at the rear. They are connected to the Y-axis translation adjustment motor 530 via a connecting plate or connecting bracket. The X-axis translation adjustment motor is mounted on the Y-axis translation adjustment motor 530 via a connecting plate or connecting bracket. The Z-axis translation adjustment motor 550 is mounted on the X-axis translation adjustment motor. The Z-axis rotary adjustment motor 560 is connected to the Z-axis translation adjustment motor 550 via 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. By separating the adjustment of the 6 axes for individual adjustment, the offset and offset angle in each direction can be adjusted independently, resulting in higher adjustment accuracy. It is possible to adjust a single offset or offset angle without affecting the position and angle in other directions.

[0062] In the above embodiments, the X-axis translation adjustment motor 540, the Y-axis translation adjustment motor 530 and the Z-axis translation adjustment motor 550 are all set as lead screw and nut motors. Lead screw and nut motors have high precision and can self-lock at any time after rotation, which is convenient for adjusting and maintaining the test precision.

[0063] According to some embodiments of this utility model, the mounting module includes a carrier plate assembly 200, which includes: a push plate 210, movably disposed on a base plate 100, which can move along the front-back direction on the base plate 100; in this embodiment, all components are disposed within an outer frame housing; the push plate 210 can slide out of the outer frame housing, i.e., to the front side of the area where the base plate 100 is located, so that the test piece can be placed in the positioning carrier plate 220 or the workpiece that has been tested can be removed; the push plate 210 can be pushed back into the outer frame housing to perform the test; a wireless charging base 230, disposed on the push plate 210, for supplying power to the test piece 600; and a positioning carrier plate 220, disposed on the wireless charging base 230, for loading and positioning the test piece 600.

[0064] According to some embodiments of this utility model, a support frame 110 is also provided on the base plate 100, and the mounting module further includes a clamping assembly 300, which includes: a first cylinder 320, disposed on the support frame 110 along the Y-axis direction; a first pressure block 310, connected to the output end of the first cylinder 320, the first pressure block 310 being used to fix the test piece 600 in the Y-axis direction, the first pressure block 310 being driven by the first cylinder 320 to move downward, that is, to move in the negative Y-axis direction, until the first pressure block 310 abuts against the test piece 600, thereby limiting the displacement of the test piece 600 in the Y-axis direction; and two second cylinders 340. The two cylinders are positioned on the base plate 100 along the X-axis and on both sides of the push plate 210. Two second pressure blocks 330 are connected to the output ends of two second cylinders 340 respectively. The two second pressure blocks 330 are used to clamp and fix the push plate 210 in the X-axis direction. Under the action of the two second cylinders 340, the two second pressure blocks 330 move towards each other at the same time to clamp the push plate 210. The positioning carrier plate 220 positions and locks the test piece 600 in the X-axis and Z-axis directions. The second pressure blocks 330 lock the push plate 210 in the X-axis direction to ensure the stability of the test piece 600 during the test and ensure the test accuracy.

[0065] 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 a push plate 210 is slidably connected to the guide rail 120. A push-pull member 211 is provided on the push plate 210, and the push-pull member 211 is used to drive the push plate 210 into or away from the area of ​​the base plate 100.

[0066] A testing method according to the second aspect of the present invention, applied to the trigger testing device with calibration function in any of the above claims, includes the following steps:

[0067] A. Load the test piece 600 onto the base plate 100;

[0068] B. The adjustment component 500 drives the probe 420 and the pressure sensor matrix 440 to approach the test piece 600 until the detection part 421 of the probe 420 and the pressure sensor matrix 440 abut against the test area of ​​the test piece 600.

[0069] C. The offset between the probe 421 and the area to be measured and the pressure value of the probe 421 are calculated by the pressure sensor matrix 440 and the corresponding signal is sent to the central control part. The central control part sends a signal to the adjustment component 500, and the adjustment component 500 adjusts the position and angle of the probe 420 to correct the offset and pressure difference between the probe 421 and the area to be measured.

[0070] According to some embodiments of the present invention, in step B above, 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 precise.

[0071] According to some embodiments of this utility model, refer to Figure 5 In step C, the detector 421 and the area to be measured are offset by a distance A in the X-axis direction.

[0072] When offset A appears on the left, the adjustment component 500 drives the probe 420 to translate a distance A to the right;

[0073] When offset A appears on the right, the adjustment component 500 drives the probe 420 to shift left by a distance A.

[0074] According to some embodiments of this utility model, refer to Figure 6 In step C, the detector 421 and the area to be measured are offset by a factor B in the Y-axis direction.

[0075] When offset B appears on the upper side, the adjustment component 500 drives the probe 420 to move downward by a distance B.

[0076] When offset B appears on the lower side, the adjustment component 500 drives the probe 420 to move upward by a distance B.

[0077] Understandably, if the detector 421 experiences a misalignment in either the X-axis or Y-axis direction relative to the area under test, correction can be achieved simply by using the X-axis translation adjustment motor 540 to drive the probe to move in the opposite direction of the misalignment along the X-axis, or by using the Y-axis translation adjustment motor 530 to move in the opposite direction of the misalignment along the Y-axis. Figure 5 As shown, offset A refers to the area where the probe 421 and the area to be measured cannot overlap in the X-axis direction, i.e., the left-right direction. 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 of ​​the pressure sensor matrix 440 that covers the entire probe 420 and is compressed forms the shape of the area to be measured. By comparing this shape with the shape of the probe 421, the shape distribution diagram of the actual position of the area to be measured and the probe 421 is obtained, thus determining offset A or offset B. Figure 5 and Figure 6 As shown, other offsets and offset angles in the following text are obtained by comparison in the same way.

[0078] According to some embodiments of this utility model, in step C, when there is no offset between the detection unit 421 and the area to be measured, and the pressure value of the first sensor 410 does not match the preset pressure value, when...

[0079] The value of the first sensor 410 is too high, so the six-axis adjustment drive assembly drives the probe 420 to retract backward.

[0080] The value of the first sensor 410 is too low, so the six-axis adjustment drive assembly drives the probe 420 forward.

[0081] According to some embodiments of this utility model, refer to Figure 7 In step C, when the detector 421 and the area to be measured are offset on both the upper and lower sides, or when the offset on one side changes from one side to the other after adjustment along the Y-axis, the adjustment component drives the detector 420 to rotate clockwise by θ1 degrees around the X-axis. If the offset increases, it rotates counterclockwise by 2θ1 degrees around the X-axis.

[0082]

[0083] Wherein, C is the width of the detector 421, and D is the width of the area to be measured detected by the detector 421.

[0084] According to some embodiments of this utility model, refer to Figure 8 In step C, when the detector 421 and the area to be measured are offset on both the left and right sides, or when the offset on one side changes from one side to the other after adjustment along the X-axis, the adjustment component drives the probe 420 to rotate clockwise by θ2 degrees around the Y-axis. If the offset increases, it rotates counterclockwise by 2θ2 degrees around the Y-axis.

[0085]

[0086] Where E is the length of the detector 421 and F is the length of the area to be measured detected by the detector 421.

[0087] It is understandable that when the width of the detector 421 differs from that of the area to be measured, and the detector 421 and the area to be measured are offset in both the vertical and horizontal directions, such as... Figure 7 As shown, when the probe 420 abuts against the area to be measured, the pressure sensor matrix 440 is compressed to form a pattern. Comparing this pattern with the pattern of the detector 421, there are detection blank areas in both the vertical and horizontal directions, with a pressure signal image formed only in the middle. Simultaneously, the left and right width values ​​are consistent with the width value of the area to be measured, indicating that the detector 421 and the area to be measured have an angle on the X-axis. Conversely, when the left and right width values ​​of the detector 421 and the area to be measured are different, and the detector 421 and the area to be measured are offset in both the left and right directions, such as... Figure 8As shown, the image generated by the pressure sensor matrix 440 and the image of the detection unit 421 have detection blank areas in both the left and right directions, and the pressure signal image is only formed in the middle. At the same time, the width value in the vertical direction is the same as the width value of the area to be measured. This indicates that the detection unit 421 and the area to be measured have a certain angle of deviation on the Y-axis. After calculating the angle of deviation using the above formula, the probe can be rotated along the X-axis or the Y-axis by the X-axis rotation adjustment motor 520 or the Y-axis rotation adjustment motor 510 to complete the deviation correction.

[0088] According to some embodiments of this utility model, refer to Figure 9 In step C, if the offset gap appears in the upper left and lower right, lower left and upper right, or appears in one corner and then reappears in another corner after adjustment along the X and Y axes, and is uneven in size, the adjustment component drives the probe 420 to rotate around the Z-axis.

[0089] When the gap is smaller on the left and larger on the right, drive probe 420 to rotate clockwise by θ3 degrees around the Z-axis;

[0090] When the gap is smaller on the left and larger on the right, drive probe 420 to rotate counterclockwise by θ3 degrees around the Z-axis.

[0091] Wherein, θ3 is the angle between the detector 421 and the area to be measured.

[0092] According to some embodiments of this utility model, refer to Figure 10 Step C also includes the following steps:

[0093] S1. Determine whether there is an upper gap between the detection unit and the area to be measured. If there is an upper gap, the adjustment component drives the probe to move downward, and then proceeds to S3. If there is no upper gap, proceeds to S2.

[0094] S2. Determine whether there is a gap on the lower side between the detection unit and the area to be tested. If there is a gap on the lower side, the adjustment component drives the probe to move upward and presses the probe against the object to be tested. If there is no gap on the lower side, proceed to S3.

[0095] S3. Determine whether there is a left gap between the detection unit and the area to be tested. If there is a left gap, the adjustment component drives the probe to move to the right and presses the object to be tested. Then proceed to S5. If there is no left gap, proceed to S4.

[0096] S4. Determine whether there is a right-side gap between the probe and the area to be tested. If there is a right-side gap, the adjustment component drives the probe to move to the left and presses the object to be tested. If there is no right-side gap, proceed to S5.

[0097] S5. Determine whether there is an angle θ3 between the detection unit and the area to be measured. If there is, the adjustment component drives the probe to rotate θ3 degrees around the Z-axis, and then returns to step S1. If there is no θ3, proceed to S6.

[0098] Wherein, θ3 is the angle between the detector and the area to be measured;

[0099] S6. Determine the difference between the width value C of the detection unit and the width value D of the area to be measured detected by the detection unit. If D < C, then the adjustment component drives the probe to rotate θ1 degrees around the Y-axis and returns to step S1.

[0100] If D < C, proceed to S7.

[0101]

[0102] Wherein, C is the width value of the detector, and D is the width value of the area to be measured detected by the detector;

[0103] S7. Determine the difference between the length value E of the detection unit and the length value F of the area to be measured detected by the detection unit. If F < E, then 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, proceed to S8.

[0104]

[0105] Wherein, E is the length value of the detector, and F is the length value of the area to be measured detected by the detector;

[0106] S8. The adjustment component drives the probe to move along the Z-axis until the value on the first sensor is the same as the preset pressure value.

[0107] Through the entire process from S1 to S8 described above, the offset and angle between the probe 420's detection part 421 and the area to be measured can be corrected and adjusted in all aspects, thereby ensuring that the detection part 421 is completely attached to the area to be measured, thus ensuring the accuracy of the measurement.

[0108] The beneficial effects of this utility model are as follows.

[0109] 1. The test piece 600 is loaded onto the carrier plate assembly 200 and 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. The positional and angular offsets between the test area and the detection part 421 of the probe 420 on the X, Y, and Z axes are determined. At the same time, the pressure value of the detection part 421 is compared with the preset pressure value by the first pressure sensor 410. The displacement and angle of the probe 420 are adjusted by the six-axis adjustment assembly 500 to eliminate 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.

[0110] 2. The test piece 600 is pressed down in the Y-axis direction by the first pressure block 310, and the push plate 210 is locked in the X-axis direction by the two second pressure blocks 330, thereby improving the stability of the test piece 600 during testing.
