Fig. 1 to 4 are a schematic perspective view, a front view, a top view and a left view of a screen testing device according to an embodiment of the present invention. As shown in fig. 1 to 4, the screen test apparatus includes a mount 1, a plurality of test heads 2, and a drive system 3. The test head 2 is used for testing in contact with a screen, and at least two of the plurality of test heads 2 are used for testing different items of the screen. The test head 2 is fixed on the mounting seat 1, and the driving system 3 is connected with the mounting seat 1 and used for driving the mounting seat 1 and the test head 2 arranged on the mounting seat 1 to move.
The drive system 3 includes an X-axis moving mechanism 31, a Y-axis moving mechanism 32, and a rotating mechanism 33. The X-axis moving mechanism 31 is used for driving the mounting base 1 to move along the X-axis direction, and the Y-axis moving mechanism 32 is used for driving the mounting base 1 to move along the Y-axis direction. The rotating mechanism 33 is used for driving the mounting base 1 to rotate around the Z axis and positioning so as to change the test head 2 for screen test. The Y axis is perpendicular to the X axis, and the Z axis is perpendicular to both the X axis and the Y axis, that is, the X axis, the Y axis, and the Z axis correspond to three coordinate axes on a rectangular spatial coordinate system. The specific directions of the X-axis, the Y-axis, and the Z-axis in space can be selected according to actual needs, and in this embodiment, the X-axis direction is taken as the vertical direction, the Y-axis direction is taken as the horizontal direction, and the Z-axis direction is taken as the front-back direction. When testing, the placing posture of the screen to be tested can be perpendicular to the X axis or the Y axis, so that the X axis moving mechanism 31 and the Y axis moving mechanism 32 can cooperate to drive the testing head 2 to complete the clicking action on the screen and the action of moving on the surface of the screen. In the present embodiment, the screen to be tested is placed perpendicular to the X axis as an example.
The X-axis moving mechanism 31 and the Y-axis moving mechanism 32 may be any power mechanism capable of driving the mount 1 to move along a straight line, or a combination of a power mechanism and a transmission mechanism, for example, the X-axis moving mechanism 31 and the Y-axis moving mechanism 32 may be a cylinder, an oil cylinder, a linear motor, or a combination of a rotary motor and a linear sliding table, and so on.
In some embodiments, the Y-axis movement mechanism 32 is a finger cylinder. The finger cylinder is an actuating device using compressed air as power, and comprises two clamping fingers 321, wherein the two clamping fingers 321 move relatively or back to back simultaneously along the axial direction, each clamping finger 321 is provided with an installation seat 1, and the installation seats 1 are fixed on the corresponding clamping fingers 321. Each mounting seat 1 is provided with a group of corresponding test heads 2, and each group of test heads 2 comprises a plurality of test heads 2. The two groups of test heads 2 can be arranged in the same and symmetrical mode, after the rotating mechanism 33 drives the mounting seats 1 to rotate and position, one corresponding test head 2 of each group of test heads 2 is opposite to the screen, and the Y-axis moving mechanism 32 can drive the two mounting seats 1 to enable the two groups of test heads 2 to be in contact with the screen and move on the screen to perform testing, so that the multi-point touch performance of the screen can be tested; alternatively, the corresponding test can be performed by adjusting the positioning of the driving system 3 or detaching the corresponding test head 2 so that only one of the test heads 2 is in contact with the screen. Preferably, test head 2 may be secured to mounting base 1 in a manner that facilitates easy removal and installation.
The rotating mechanism 33 may include a motor, a rotating cylinder, and other power mechanisms that output a rotating motion, or may be a combination of a power mechanism that outputs a linear motion and a reversing mechanism (for example, a combination of a linear cylinder and a worm gear), which is not limited in this embodiment of the present invention.
Preferably, drive system 3 further includes a rotation limiting mechanism 34, and rotation limiting mechanism 34 is configured to limit the rotation angle of rotation mechanism 33, so as to position the action of rotation mechanism 33, so that test head 2 can be well positioned to be aligned with the screen when test head 2 for screen testing is switched. The rotation limiting mechanism 34 may include a sensor for detecting the position of the object, such as a photoelectric switch or a hall sensor, and a corresponding control circuit connected to the rotation mechanism 33, and may further include a stopper or the like that blocks the rotation mechanism 33 from moving continuously at a certain position by physical contact. The specific position of the rotation limiting mechanism 34 can be designed according to the relative distribution position among the plurality of test heads 2. For example, referring to fig. 1 to 4, each of the clamping fingers 321 of the finger cylinder is provided with a corresponding set of test heads, and the set of test heads includes two oppositely arranged test heads 2, that is, an included angle between the two test heads 2 is 180 degrees. The rotation limiting mechanism 34 includes a stopper 341 and two buffers 342, the stopper 341 is fixed to the rotation output end of the rotation mechanism 33, the two buffers 342 are disposed in parallel and symmetrically on two sides of the rotation output end of the rotation mechanism 33, and specifically may be disposed on the body of the rotation mechanism 33 or connected to the rotation mechanism 33 through a support 343 fixed on the rotation mechanism 33. Therefore, when the rotating mechanism 33 drives the mounting seat 1 to rotate 180 degrees to change the test head 2 opposite to the screen, the stopper 341 is contacted with one of the buffers 342 to stop the rotating mechanism 33; when it is necessary to change over the test head 2 for screen testing again, the rotating mechanism 33 is rotated in reverse by 180 °, and the stopper comes into contact with the other buffer 342 and stops the rotation of the rotating mechanism 33.
The screen testing device further comprises a fixing seat 5, and the fixing seat 5 can be installed on an operation table, a wall or other positions and used for supporting and fixing the screen testing device. The driving system 3 is arranged on the fixed seat 5. The X-axis moving mechanism 31, the Y-axis moving mechanism 32, and the rotating mechanism 33 may be connected in any connection order, and the connection relationship among the three may be designed according to the requirements of the screen test items, the specific mechanism form, the driving force, and the weight of the mechanism itself, for example, the X-axis moving mechanism 31 that can maintain the motion stability easily may be installed on the fixing base 5.
In some embodiments, the Y-axis moving mechanism 32 may be coupled to the mount 1. For example, when the Y-axis moving mechanism 32 is a finger cylinder, it is arranged at the extreme end of the driving system 3 and directly connected to the mount 1, so that the overall structure of the driving system 3 can be simplified. Meanwhile, the output end of the X-axis moving mechanism 31 may be connected to the rotating mechanism 33, and the output end of the rotating mechanism 33 may be connected to the Y-axis moving mechanism 32; alternatively, the output end of the rotation mechanism 33 may be connected to the X-axis movement mechanism 31, and the output end of the X-axis movement mechanism 31 may be connected to the Y-axis movement mechanism 32.
The test head 2 comprises contacts 21, the contacts 21 being for testing in direct contact with the screen. The specific shape and configuration of the contacts 21 may be designed according to the desired test items to be performed on the screen. For example, the contact member 21 may be a contact 211, and the end of the contact 211 is arc-shaped, and may be used to simulate a human finger clicking and swiping a screen. Specifically, the driving system 3 can perform a click operation on a predetermined position on the screen by driving the contact 211 to move the contact 211 in a direction perpendicular to the screen (in this embodiment, in the X-axis direction); the screen may also be swiped by moving the contact 211 in a direction parallel to the screen (in this embodiment, in the Y-axis direction) after the contact 211 contacts the screen. Two parallel test heads 2 containing the contact 211 can be arranged to simultaneously contact with the screen, and the multi-touch performance of the screen can be tested. For another example, the contact member 21 may be a roller 212, and the roller 212 is used for rolling the screen to test the pressure resistance of the screen. Specifically, the driving system 3 moves the corresponding test head 2 to the screen, brings the roller 212 into contact with the screen and applies a certain pressure to the screen, and then drives the test head 2 to move in a direction parallel to the screen (in the Y-axis direction in this embodiment), so that the roller 212 rolls on the screen. It should be understood that the specific form of the contact 21 is not limited to the above two, and those skilled in the art can select an appropriate contact 21 according to the needs of a specific test item.
A plurality of test heads 2 are fixed on the mounting seat 1, a certain included angle can be formed between the test heads 2 for testing different projects and the included angles are distributed around the rotating shaft of the rotating mechanism 33, for example, four different test heads 2 can be arranged to be distributed radially, so that each test head 2 faces different positions, and the rotating mechanism 33 drives the mounting seat 1 to rotate by a preset angle to change the test heads 2 for testing the screen. Of course, other arrangements may be used to position the plurality of test heads 2.
In some embodiments, the test head 2 further includes a fixing block 22 and a connecting rod 23, and the fixing block 22 is fixedly connected to the mounting base 1. The link 23 is provided on the fixed block 22 and is movable in the X-axis direction relative to the fixed block 22. The link has a first end and a second end, the contact member 21 being mounted on the first end of the link 23, the second end being the end of the link 23 opposite the first end.
Preferably, test head 2 further comprises a buffer structure for buffering contacts 21 to prevent damage to the screen due to hard contact of contacts 21 with the screen. The buffer structure may include a spring, an elastic material, a pneumatic buffer device, and the like, which enable the contact member 21 to have a certain floating amount perpendicular to the screen direction when contacting the screen.
Fig. 5 is a schematic sectional view of the screen test apparatus of the embodiment of the present invention along the direction a-a in fig. 3. Referring to fig. 5, in some embodiments, the fixing block 22 has a first mounting hole 221 penetrating in the X-axis direction, and the link 23 is inserted into the first mounting hole 221 and is movable along the first mounting hole 221. The first end of the link 23 has a stopper 231, and the stopper 231 has a size larger than that of the first mounting hole 221, and more particularly, a length of a widest cross-sectional portion of the stopper 231 is larger than a diameter of the first mounting hole 221, whereby the stopper 231 is opposed to an end surface of the fixed block 22 to prevent the link 23 from coming off. The buffer structure comprises a first elastic member 24, and the first elastic member 24 is abutted between the contact member 21 and the fixed block 22, thereby providing a certain elastic supporting force for the connecting rod 23 and the contact member 21 and buffering when the contact member 21 is contacted with the screen. The first resilient member 24 may be a spring or other resilient element. Taking the first elastic member 24 as an example of a spring, during assembly, the first end of the connecting rod 23 may first pass through the first mounting hole 221, then the first elastic member 24 is sleeved on the first end of the connecting rod 23, and then the contact member 21 is connected with the connecting rod 23, so that the first elastic member 24 is abutted between the contact member 21 and the fixed block 22. The buffer structure can be suitable for test heads with various different contact elements 21, preferably, the buffer structure can be applied to the test head with the contact element 21 as the contact 211, can provide buffer for the contact 211 and simultaneously well guarantee the motion linearity of the contact 211, and avoids the contact 211 from shaking circumferentially to influence the contact accuracy of the contact 211 and a preset position of a screen.
Referring again to fig. 5, in some embodiments, the fixing block 22 has a second mounting hole 222 along the X-axis direction, the second mounting hole 222 is a blind hole, the buffer structure includes a second elastic element 25 and a limit pin 26, the second end of the connecting rod 23 is disposed in the second mounting hole 222, and the second elastic element 25 is disposed between the bottom of the second mounting hole 222 and the second end (i.e., the end far away from the contact element 21) of the connecting rod 23. The sidewall of the second mounting hole 222 has a strip-shaped hole 223 extending along the X-axis direction, and the limit pin 26 is inserted into the strip-shaped hole 223 and fixedly connected to the connecting rod 23. Due to the limitation of the strip-shaped hole 223 and the limit pin 26, after the contact piece 21 is contacted with the screen, the connecting rod 23 and the contact piece 21 can float in the length range of the strip-shaped hole 223 for buffering. Preferably, the buffer structure can be applied to a contact head of which the contact element is the roller 212, compared with a contact element such as the contact 211 which adopts an insertion connection mode, the dismounting process of the roller 212 and the connecting rod 23 is more complicated, and the dismounting of the test head can be facilitated by adopting the buffer structure.
Optionally, the screen testing apparatus further comprises a product positioning device for fixing and positioning the product and the screen during the testing process, so as to prevent the screen from shifting during the testing process.
Further, the screen test apparatus may further include a moving platform moving on a plane perpendicular to the X-axis. The mobile platform can drive the screen testing device to integrally move, so that the screen testing device can be conveniently positioned or moved among different stations.

Of course, the test items that can be performed by the screen test apparatus are not limited to the above, and those skilled in the art can design the test items and procedures according to actual needs, which is not limited to this in the embodiment of the present invention.
