[0031] The specific embodiments of the application have been shown and described in the above drawings and the following description. These drawings and detailed description are not intended to limit the scope of the application in any way, but to illustrate the application by reference to specific embodiments. DETAILED DESCRIPTION

[0032] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The same numbers are used in different drawings to represent the same or similar elements. The following detailed description is not limiting in any way on the scope of the application, which is defined in the appended claims. Rather, the following detailed description is intended to describe some embodiments of the application in sufficient detail to enable one skilled in the art to practice the application, at least in combination with the appended claims.

[0033] The technical solutions of the application and how the technical solutions solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the application will be described below with reference to the drawings.

[0034] The screen testing device provided by the embodiments of the application can be used for testing a display screen, and can be specifically used for testing the strength, hardness and pressure resistance of the display screen, and can also be used for testing the touch screen sensitivity of a touch screen with a touch function. For example, in the embodiments of the application, the screen testing device can be used for testing the touch screen of an electronic device such as a mobile phone or a tablet computer, and for detecting whether the touch screen function of the mobile phone is normal.

[0035] As mentioned in the background, when testing the screen of a mobile phone or a tablet in the related art, the screen needs to be fixed on a testing device, and then a screen drawing structure is used to draw the screen. In order to meet the needs of users, mobile phones and tablets are generally provided with multiple models and sizes, and mobile phones or tablets of different sizes have screens of different sizes. The testing device in the related art can only test screens of a certain size, and the testing range is small. The screen testing device provided in the present application can overcome the shortcomings of the related art. When the positioning assembly is used to position the product to be tested, the positioning space can be reasonably adjusted according to the size of the product to be tested, so as to adapt to the positioning of products to be tested of different sizes, thereby increasing the application range compared with the related art.

[0036] For ease of description, please refer to Figure 1 , Figure 1 The direction of the X-axis is parallel to the first direction, the direction of the Y-axis is parallel to the second direction, and the direction of the Z-axis is parallel to the third direction. The first direction, the second direction and the third direction are perpendicular to each other.

[0037] In an embodiment, please refer to Figure 1 and Figure 2 The screen testing device includes a rack 10, a conveying assembly 20, a testing module 30 and a positioning assembly 40. The rack 10 is the main structure of the screen testing device, and serves to support and install other parts.

[0038] The conveying assembly 20 and the positioning assembly 40 are both arranged on the rack 10. The conveying assembly 20 is used to convey the product to be tested, and the product to be tested is placed on the conveying structure of the conveying assembly 20. The conveying assembly 20 can convey the product to be tested along the first direction.

[0039] The testing module 30 is located on the path along which the conveying assembly 20 conveys the product to be tested. There is a testing position on the path. The conveying assembly 20 can convey the product to be tested to the testing position. The testing module 30 can test the screen of the product to be tested located on the testing position.

[0040] The positioning assembly 40 is located on the conveying path of the conveying assembly 20. The positioning assembly 40 includes a first positioning module 41 and a second positioning module 42. The first positioning module 41 includes a first clamping part 413 arranged to open and close along the second direction. The second positioning module 42 includes a second clamping part 422 arranged to open and close along the first direction. The first clamping part 413 and the second clamping part 422 form a containing position for containing the product to be tested.

[0041] The accommodation position is located at the test position, and the conveying assembly 20 can convey the product to be tested to the accommodation position when conveying the product to be tested. The opening and closing of the first clamping part 413 can enable the first clamping part 413 to clamp the product to be tested in the second direction, so that the product to be tested is relatively fixed in the first direction. The opening and closing of the second clamping part 422 can enable the second clamping part 422 to clamp the product to be tested in the first direction, so that the product to be tested is relatively fixed in the second direction. Therefore, the opening and closing of the first clamping part 413 and the second clamping part 422 can limit the movement of the product to be tested in the first direction and the second direction.

[0042] It should be noted that the first direction and the second direction are parallel to the conveying plane of the conveying assembly 20, and the first clamping part 413 and the second clamping part 422 cooperate to limit the lateral movement of the product to be tested at the test position. When the test module 30 tests the screen, the end part for testing needs to abut against the screen, and then the end part is moved to realize the sliding of the end part on the screen. The movement plane of the end part for testing is parallel to the plane in which the first direction and the second direction lie.

[0043] By arranging the first positioning module 41 and the second positioning module 42, the first clamping part 413 of the first positioning module 41 and the second clamping part 422 of the second positioning module 42 cooperate to limit the movement of the product to be tested in the first direction and the second direction, so that when the test module 30 tests the screen, the product to be tested is less likely to deviate from the position, which is beneficial to the smooth progress of the screen test of the product to be tested. In addition, the first clamping part 413 and the second clamping part 422 of the present application are both arranged to be openable and closable. In this way, the first clamping part 413 can be opened and closed by a corresponding distance according to the size of the product to be tested in the second direction, and the second clamping part 422 can be opened and closed by a corresponding distance according to the size of the product to be tested in the first direction, which is beneficial to adapt to fix products to be tested of different sizes, so that the screen test device of the present application can perform screen test on more sizes of products to be tested, and has a wide application range.

[0044] Illustratively, the placement surface of the rack 10 is generally the ground, and the bottom end of the rack 10 can further be provided with a plurality of bottom wheels 12. The plurality of bottom wheels 12 are respectively arranged at the corner positions of the bottom end of the rack 10. By arranging the plurality of bottom wheels 12, the rack 10 can be supported and moved conveniently.

[0045] Illustratively, the bottom end of the rack 10 can further be provided with a plurality of support seats 13. The support seats 13 are arranged to be telescopically arranged along the third direction. By adjusting the telescopic degree of the support seats 13, the bottom end of the support seats 13 can be adjusted to abut against the ground to support the rack 10, and can be used to fix the position of the rack 10, so that the rack 10 cannot be moved by the bottom wheels 12. After the bottom end of the support seats 13 is retracted away from the ground, the rack 10 can be moved by the bottom wheels 12.

[0046] For example, in order to reduce the material of the rack 10 and reduce the weight of the rack 10, the rack 10 can be combined by a plurality of rack bars and a mounting platform, and the conveying assembly 20 and the positioning assembly 40 are arranged on the mounting platform.

[0047] The first clamping part 413 and the second clamping part 422 can be opened and closed in various ways. For example, in some achievable ways, the first positioning module 41 includes two first clamping parts 413 arranged to move in the first direction. The two first clamping parts 413 can move towards or away from each other in the second direction to increase or decrease the distance between the two first clamping parts 413. The first positioning module 41 further includes a first driving part 411 for driving the two first clamping parts 413 to open and close in the first direction.

[0048] The second positioning module 42 includes two second clamping parts 422 arranged to move in the first direction. The two second clamping parts 422 can move towards or away from each other in the second direction to increase or decrease the distance between the two second clamping parts 422. The second positioning module 42 further includes a second driving part 421 for driving the two second clamping parts 422 to open and close in the second direction.

[0049] For example, the two first clamping parts 413 can be driven by two first driving parts 411 respectively, or can be driven by only one first driving part 411. When the two first clamping parts 413 are driven by one first driving part 411, the first driving part 411 has two driving ends, and the driving directions of the two driving ends are opposite.

[0050] It should be noted that the second driving part 421 for driving the two second clamping parts 422 can be similar to the first driving part 411, and will not be described in detail here.

[0051] It should be noted that when there are two first clamping parts 413 and two second clamping parts 422, if it is desired to change the distance between the two first clamping parts 413 and the two second clamping parts 422, the two first clamping parts 413 and the two second clamping parts 422 can be moved simultaneously, or one of the clamping parts can be fixed, and the other clamping part can be driven by the driving part to move towards or away from the fixed clamping part to adjust the distance between the two clamping parts.

[0052] The first driving part 411 and the second driving part 421 can be hydraulic cylinders, air cylinders or driving motors. When the first driving part 411 and the second driving part 421 are driving motors, the first driving part 411 and the second driving part 421 can be connected to the clamping parts through connecting assemblies, for example, two nuts are respectively connected to the same screw rod to connect the two first clamping parts 413 or the two second clamping parts 422, and the screw rod is coaxially connected to the output shaft of the motor, and the two nuts are slidably arranged along the first direction or the second direction.

[0053] In some possible implementation manners, the first clamping part 413 comprises a first connecting piece 4131 and a clamping jaw 4132, the first connecting piece 4131 is used for connecting the output end of the first driving part 411, and the clamping jaw 4132 is connected to the first connecting piece 4131, and when the first driving part 411 drives the first connecting piece 4131 to move, the clamping jaw 4132 moves with the first connecting piece 4131, and the clamping jaw 4132 is used for clamping the product to be detected during the movement.

[0054] In some possible implementation manners, the first connecting piece 4131 can be provided in plurality, and the plurality of first connecting pieces 4131 are equidistantly arranged along the first direction, and each first connecting piece 4131 is connected with at least one clamping jaw 4132.

[0055] The second clamping part 422 comprises a second connecting piece 4221, a fixing part 4222 and a clamping piece 4223, the second connecting piece 4221 is used for connecting the output end of the second driving part 421, the fixing part 4222 is used for connecting the second connecting piece 4221 and the clamping piece 4223, and when the second driving part 421 drives the second connecting piece 4221 to move, the clamping piece 4223 moves with the second connecting piece 4221, so that the clamping piece 4223 can clamp the product to be detected.

[0056] In some possible implementation manners, an end surface of the clamping piece 4223 for clamping the product to be detected is provided with a limiting groove 42231, and when the clamping piece 4223 clamps the product to be detected, the end portion of the product to be detected can be accommodated in the limiting groove 42231. The cross section of the limiting groove 42231 can be a shape matched with the end portion of the product to be detected, or the cross section of the limiting groove 42231 can be a “V” shape, a semicircle or the like, so that the end portion of the product to be detected can abut against the groove wall of the limiting groove 42231 to limit the position of the product to be detected relative to the clamping piece 4223.

[0057] In some possible implementation manners, please refer to Figure 1 and Figure 2The fixed part 4222 of the second clamping part 422 and the conveying assembly 20 are spaced apart along the third direction, and the fixed part 4222 is located above the conveying assembly 20. Specifically, the fixed part 4222 of the second clamping part 422 is located above the conveying assembly 20 along the second direction, and the fixed part is spaced apart from the end surface of the conveying assembly 20 and the conveying plane of the conveying assembly 20. The spacing can also be regarded as the spacing between the fixed part and the conveying assembly 20 along the third direction. The size of the spacing is greater than or equal to the size of the product to be detected along the third direction.

[0058] Because the second clamping part 422 moves along the first direction, and the conveying assembly 20 also conveys the product to be detected along the first direction, in order to avoid the second clamping part 422 from blocking the product to be detected from entering the detection position, the fixed part 4222 of the second clamping part 422 is arranged above the conveying assembly 20. In this way, when the conveying assembly 20 conveys the product to be detected, the product to be detected can pass through the gap between the fixed part 4222 and the conveying assembly 20, thereby avoiding blocking the product to be detected.

[0059] In order to avoid the clamping part 4223 from blocking the product to be detected from being transported to the detection position, the clamping part 4223 is also located above the detection position when the clamping part 4223 is in the initial position, so that the product to be detected can be smoothly transported to the detection position. In order to ensure that the clamping part 4223 can smoothly clamp the product to be detected, when the fixed part 4222 is located above the conveying assembly 20, the clamping part 4223 can also be movably connected to the fixed part 4222 along the third direction. At this time, the fixed part 4222 can also be provided with a driving structure for driving the clamping part 4223 to move up and down along the third direction, such as a linear motor, a pneumatic cylinder or a hydraulic cylinder, etc. In this way, when the conveying assembly 20 transports the product to be detected to the detection position, the clamping part 4223 can be driven to move towards the product to be detected by the driving structure, so that the clamping part 4223 can be arranged opposite to the end of the product to be detected along the first direction. Then, the second connecting part 4221 is driven to move along the first direction by the second driving part 421, so as to drive the clamping part 4223 to clamp the product to be detected along the first direction.

[0060] In another implementable manner, when the fixed part 4222 and the conveying assembly 20 are spaced apart along the third direction, the product to be detected can also be transported to the clamping jaw 4132, and then the first clamping part 413 is driven to move along the third direction, so as to move the product to be detected to the two ends along the first direction and arrange the two ends opposite to the clamping part 4223.

[0061] Specifically, the first positioning module 41 further comprises a third driving part 412 connected to the rack 10, and a driving end of the third driving part 412 is capable of reciprocating movement along the third direction, and the third driving part 412 can be but is not limited to a pneumatic cylinder, a hydraulic cylinder or the like. A fixed block is further connected to the driving end of the third driving part 412, and the first driving part 411 is connected to the driving end of the third driving part 412 through the fixed block, so that the first driving part 411 can be movably arranged along the third direction with the driving end of the third driving part 412, and the first clamping part 413 is further connected to the first driving part 411 through a first connecting piece 4131, and thus the third driving part 412 is used for driving the first clamping part 413 along the third direction towards the clamping jaw 4132 of the second clamping part 422.

[0062] It should be noted that the detection position at this time is located on the first clamping part 413, and the conveying assembly 20 can convey the product to be detected to the first clamping part 413 when conveying the product to be detected, and then move the product to be detected along the third direction to between the two clamping pieces 4223 under the driving of the third driving part 412.

[0063] Specifically, the clamping jaw 4132 further comprises a clamping part 41322 and a supporting part 41321, one end of the supporting part 41321 is connected to the first connecting piece 4131, and the other end of the supporting part 41321 is connected to the clamping part 41322, and the spacing between the supporting parts 41321 of the two opposite clamping jaws 4132 is smaller than the size of the product to be detected in the second direction, so that the two opposite supporting parts 41321 can form a supporting table, and the end face where the supporting part 41321 and the clamping part 41322 are connected forms a supporting surface. In the initial position, the end face where the supporting part 41321 and the clamping part 41322 are connected is flush with the bottom surface of the product to be detected, and the conveying assembly 20 can convey the product to be detected to between the oppositely arranged supporting parts 41321, and the product to be detected is lapped on the end face where the supporting part 41321 and the clamping part 41322 are connected.

[0064] When the product to be detected is completely supported on the supporting part 41321, the first connecting piece 4131 can be moved towards each other by the first driving part 411, and the product to be detected is clamped at both ends in the second direction by the two opposite clamping parts 41322, and at this time the space formed by the supporting part 41321 and the clamping part 41322 for clamping the product to be detected can also be used as a detection position. After clamping the product to be detected, the entire second clamping part 422 can be moved along the third direction by the third driving part 412, so that the product to be detected is moved between the two separated clamping jaws 4132, and then the two second connecting pieces 4221 are moved towards each other by the second driving part 421, so as to drive the two clamping jaws 4132 to move towards each other, and thus clamping the product to be detected at both ends in the first direction.

[0065] In some possible implementation manners, referring to Figure 1 and Figure 5 The test module 30 of the test device in the embodiment of the present application comprises a base 31 and a test head 32, the base 31 is movably arranged on the rack 10, and the movable range of the base 31 is arranged within the detection position range of the product to be detected. The test head 32 is used to directly contact the screen of the product to be detected, so as to test the screen. The test head 32 comprises a mounting seat 321 and a test piece 322, the mounting seat 321 is movably connected to the base 31 along a third direction, and the test piece 322 is connected to the mounting seat 321.

[0066] The base 31 can move in a predetermined plane, the predetermined plane is parallel to the planes in which the first direction and the second direction are located, and when the product to be detected is located at the detection position, the screen of the product to be detected is also parallel to the movement plane of the base 31. When it is necessary to detect the screen of the product to be detected located at the detection position, the base 31 is controlled to move, so that the test piece 322 moves to the top of the screen of the product to be detected, at this time, the mounting seat 321 is controlled to move along the third direction towards the screen to abut against the end of the test piece 322, and then the base 31 is controlled to move, so as to drive the end of the test piece 322 to slide on the screen, so as to realize the detection of the screen.

[0067] For example, the test piece 322 is a conductive silica gel roller, the roller is rotatably connected to the mounting seat 321, and when the mounting seat 321 moves with the base 31, the roller can roll on the screen. By arranging the test piece 322 as the roller, when the test piece 322 is used to test the screen, the friction between the test piece 322 and the screen is rolling friction, so that the risk of damaging the screen can be reduced.

[0068] For example, the test piece 322 can also be a ball, the ball is rotatably connected to the mounting seat 321, and by arranging the test piece 322 as the ball, the test piece 322 can be rotated by 360° on the mounting seat 321, so that the test piece 322 can slide on the screen in any direction.

[0069] In some possible implementation manners, the rack 10 is further provided with a mechanical arm 60, the mechanical arm 60 has at least two degrees of freedom of movement along the first direction and the second direction, the base 31 is connected to the moving end of the mechanical arm 60, and the mechanical arm 60 is used to drive the base 31 to move along the first direction and the second direction.
