Description

Technical Field

[0001] The present application relates to the field of touch screens, and in particular to a structure that facilitates batch testing of touch screens. Background Art

[0002] During the aging performance test and bad pixel test of the touch screen, it is usually necessary to light up the touch screen and play the test video on the touch screen in a rotation. After 48 hours (or longer) of uninterrupted power testing, the bad pixels and / or aging of the touch screen will be highlighted for easy maintenance or scrapping.

[0003] However, in actual application, after passing the first round of performance testing, the operator places the touch screen on the test stand in an orderly manner, and moves the test stand with the touch screen to the test area. Because each touch screen requires a power cord for power supply, in the existing test area, a suspended power supply method is usually adopted, that is, a main line is spanned above the test area, and the main line is connected to several branches, and the several branches are all used to connect the power cord. When the test stand with the touch screen is pushed into the test area, the operator plugs the power cord into the power interface of the touch screen in an orderly manner. At this time, the test equipment starts to detect the touch screen and record the detection data through the controller.

[0004] However, since there are a large number of power lines connected along the main line, a large number of power lines are arranged in a messy manner in the test area, which is inconvenient for operators to operate. At the same time, there are safety hazards and there is room for improvement. Utility Model Content

[0005] In order to improve the convenience of touch screen testing, the present application provides a structure that facilitates batch testing of touch screens.

[0006] The present application provides a structure that facilitates batch testing of touch screens using the following technical solutions:

[0007] A structure that facilitates batch testing of touch screens, including a sliding carrier, wherein the sliding carrier is provided with a plurality of placement positions along the length direction, wherein the placement positions are used to place the touch screen, and a main line is provided inside the sliding carrier along the length direction, wherein the main line is used for an external power supply, and a power line is provided at any of the placement positions, and one end of the power line is connected to the main line, and the other end of the power line is plugged into and matched with a power interface of the touch screen.

[0008] By adopting the above technical solution, after the touch screen has passed the performance test, the operator places the touch screen on the placement position, and then moves the sliding carrier with the touch screen to the test area. Since a main line is provided in the sliding carrier, the operator connects the main line to the power terminal of the test area, and inserts the power cord connected to the main line into the power interface of the touch screen. At this time, the touch screen located in the placement position is in a powered-on state. Compared with the suspension power supply method, the power cord arrangement of the sliding carrier in the test area is relatively neat, and there is almost no problem of messy arrangement of the power cords, which reduces the safety hazards in the test area and plays a positive role in improving the convenience of touch screen testing.

[0009] Preferably, the sliding carrier frame includes a base frame and a vertical frame, and a plurality of the vertical frames are provided. The plurality of vertical frames are evenly distributed along the length direction of the base frame, and a placement position is formed between every two adjacent vertical frames; shock-absorbing pads are provided on the base frame and the vertical frames, and the shock-absorbing pads are configured as silicone shock-absorbing pads. When the touch screen is placed in the placement position, the lower end and the rear shell of the touch screen abut against the shock-absorbing pads.

[0010] By adopting the above technical solution, the placement position is formed by isolating two adjacent vertical frames. When the touch screen is placed on the placement position, the touch screen is supported by the two adjacent vertical frames, so that the touch screen is stably placed in the placement position. At the same time, since the shock-absorbing pad made of silicone material is soft and easy to deform, when the touch screen is placed on the placement position, the probability of scratches or displacement of the touch screen is reduced through the buffering effect of the shock-absorbing pad, which plays a positive guiding role in maintaining the appearance quality of the touch screen.

[0011] Preferably, the chassis is formed by welding a square tube, and the main line is passed through the chassis along the length direction of the chassis.

[0012] By adopting the above technical solution, since the interior of the square tube is hollow, it is convenient for the main line to pass through the frame. At the same time, it plays a positive guiding role in reducing the overall weight of the frame, making it convenient for operators to move the sliding carrier.

[0013] Preferably, self-locking universal wheels are arranged in a matrix at the corners of the lower surface of the base frame.

[0014] By adopting the above technical solution, since the self-locking universal wheels can roll with the ground, the resistance encountered by the sliding carrier when it moves is reduced. The operator can easily move the sliding carrier through the self-locking universal wheels. At the same time, when the operator moves the sliding carrier to the specified position in the test area, the self-locking effect of the self-locking universal wheels can make the sliding carrier as a whole stay stably at the specified position. The positioning method is simple and easy to operate.

[0015] Preferably, a wire management slot is provided on the stand, and the power cord is snap-fitted into the wire management slot.

[0016] By adopting the above technical solution, the operator can connect the power cord to the cable management trough, so that the power cord can be arranged in an orderly manner on the stand, which solves the problem of messy arrangement of the power cord to a certain extent; at the same time, the cable management trough can control the extended length of the power cord so that it can adapt to the power supply requirements of touch screens of different sizes.

[0017] Preferably, the base frame is provided with a plurality of sockets along the length direction, any one of the sockets is located below the vertical frame, and a plurality of the sockets are connected to the main line.

[0018] By adopting the above technical solution, the power cord is indirectly connected to the main line by plugging into the socket. Compared with the method of directly connecting the power cord to the main line, the wiring method of the present application can remove the power cord along the socket to facilitate replacement of power cords of different specifications to meet the power supply needs of touch screens with different wiring requirements without the need to set up a variety of sliding carriers of different sizes, and is highly practical.

[0019] Preferably, a detection camera is provided on any one of the stands, the detection camera is electrically connected to the controller, the detection end of the detection camera faces the placement position, the detection end of the detection camera is facing the touch screen, and the detection cameras have independent numbers respectively, and the number of numbers corresponds one-to-one to the number of the placement positions.

[0020] By adopting the above technical solution, since the codes of several detection cameras correspond to different placement positions, the placement positions can be numbered. When any detection camera detects that the touch screen has problems such as bad pixels, the operator can directly observe the specific position of the current touch screen through the controller, so as to quickly remove the unqualified touch screen along the placement position.

[0021] Preferably, an angle adjustment member is provided on the stand, and the base of the detection camera is fixedly connected to the adjustment end of the angle adjustment member.

[0022] By adopting the above technical solution, the angle of inclination of the detection camera along the stand can be adjusted through the angle adjustment member, so that the detection camera can meet the detection requirements of touch screens of different sizes, so that the detection camera can always be directly opposite the touch screen.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Compared with the suspension power supply method, the power lines of the sliding carrier of the present application are arranged relatively neatly in the test area, and there is almost no problem of messy arrangement of power lines, which reduces the safety hazards in the test area and plays a positive role in improving the convenience of touch screen testing;

[0025] 2. The operator can clip the power cord into the cable management slot, so that the power cord can be arranged in an orderly manner on the stand, which solves the problem of messy power cord arrangement to a certain extent; at the same time, the cable management slot can control the length of the power cord to adapt to the power supply requirements of touch screens of different sizes;

[0026] 3. The angle of inclination of the detection camera along the stand can be adjusted through the angle adjustment piece, so that the detection camera can always face the touch screen. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-2 This application is described in further detail.

[0031] The present application embodiment discloses a structure that facilitates batch testing of touch screens. Figure 1 A structure for batch testing of touch screens includes a sliding carrier 1, wherein the sliding carrier 1 is provided with a plurality of placement positions 2 along the length direction, the placement positions 2 are used to place the touch screen, a main line 3 is provided in the extension direction inside the sliding carrier 1, the main line 3 is used for an external power supply, the main line 3 can be a conventional power supply cable, and its wire diameter can be adjusted according to the actual required power, a power line 4 is provided on any placement position 2, and one end of the power line 4 is connected to the main line 3, and the other end of the power line 4 is plugged into the power interface of the touch screen.

[0032] The implementation principle of a structure that facilitates batch testing of touch screens in an embodiment of the present application is as follows: after the touch screen has undergone performance testing, the operator places the touch screen on a placement position 2, and then moves the sliding carrier 1 on which the touch screen is placed into the test area. Since a main line 3 is provided in the sliding carrier 1, the operator connects the main line 3 to the power terminal of the test area, and inserts the power line 4 connected to the main line 3 into the power interface of the touch screen. At this time, the touch screen located at the placement position 2 is in a powered-on state. Compared with the suspension power supply method, the sliding carrier 1 of the present application has relatively neatly arranged power lines 4 in the test area, and there is almost no problem of messy arrangement of the power lines 4, which reduces the safety hazards in the test area and plays a positive guiding role in improving the convenience of touch screen testing.

[0033] Reference Figure 1 and Figure 2 The sliding carrier 1 includes a base frame 11 and a vertical frame 12. A plurality of vertical frames 12 are provided. The plurality of vertical frames 12 are evenly distributed along the length direction of the base frame 11, and the plurality of vertical frames 12 are vertically arranged with respect to the base frame 11 and are welded and fixed to the base frame 11. A placement position 2 is formed between every two adjacent vertical frames 12. Shock-absorbing pads 5 are provided on the base frame 11 and the vertical frames 12. The shock-absorbing pads 5 are configured as silicone shock-absorbing pads 5. When the touch screen is placed in the placement position 2, the lower end of the touch screen and the rear shell abut against the shock-absorbing pads 5.

[0034] Therefore, the placement position 2 is formed by isolating two adjacent stands 12. When the touch screen is placed in the placement position 2, the support of the two adjacent stands 12 allows the touch screen to be stably placed in the placement position 2 in an inclined state. At this time, the spatial position of the touch screen can be directly opposite the test equipment, so that the test equipment can detect the touch screen. At the same time, since the shock-absorbing pad 5 made of silicone material is soft and easy to deform, when the touch screen is placed on the placement position 2, the cushioning effect of the shock-absorbing pad 5 reduces the probability of scratches or displacement of the touch screen, which plays a positive guiding role in maintaining the appearance quality of the touch screen.

[0035] Reference Figure 1 and Figure 2 The chassis 11 is formed by welding a square tube, and the main line 3 is passed through the chassis 11 along the length direction of the chassis 11.

[0036] Specifically, the outer contour of the base frame 11 is set in a rectangular shape, and the square tube is made of galvanized steel. The square tube is cut into a size that meets the design requirements and welded to each other. At this time, both ends of the square tube along the length direction are in an open state to facilitate the passage of the main line 3. The main line 3 is covered by the base frame 11 without the need to use other components to fix the main line 3; at the same time, because the inside of the square tube is hollow, it plays a positive guiding role in reducing the overall mass of the base frame 11, which is convenient for the operator to move the sliding carrier 1.

[0037] Furthermore, self-locking universal wheels 6 are arranged in a matrix at the corners of the lower surface of the base frame 11. There are four self-locking universal wheels 6, which are installed in a matrix on the lower surface of the base frame 11. Since the self-locking universal wheels 6 can cooperate with the ground for rolling, the resistance encountered by the sliding carrier 1 when moving is reduced. The operator can move the sliding carrier 1 conveniently through the self-locking universal wheels 6. At the same time, when the operator moves the sliding carrier 1 to the specified position of the test area, the self-locking effect of the self-locking universal wheels 6 can make the sliding carrier 1 as a whole stably stay in the specified position. The positioning method is simple and easy to operate.

[0038] Reference Figure 1 and Figure 2 A wire management groove 7 is provided on the stand 12, and the power cord 4 is engaged with the wire management groove 7. The wire management groove 7 is opened along the height direction of the stand 12 and is formed by a depression on the surface of the stand 12 along the thickness direction. Therefore, the operator can engage the power cord 4 in the wire management groove 7, so that the power cord 4 can be arranged in an orderly manner on the stand 12, which solves the problem of the messy arrangement of the power cord 4 to a certain extent. The length of the power cord 4 can be controlled by the wire management groove 7, so that it can adapt to the power supply requirements of touch screens of different sizes.

[0039] Furthermore, a plurality of sockets 8 are provided in the extension direction of the base frame 11, and any one of the sockets 8 is located below the vertical frame 12 and is fixed to the base frame 11 by bolts, and the plurality of sockets 8 are connected to the main line 3, and the power cord 4 is indirectly connected to the main line 3 by plugging in the sockets 8. Compared with the method in which the power cord 4 is directly connected to the main line 3, the wiring method of the present application can disassemble the power cord 4 along the socket 8 to facilitate replacement of power cords 4 of different specifications, thereby meeting the power supply requirements of touch screens with different wiring requirements, without the need to set up a plurality of sliding carrier frames 1 of different sizes, and is highly practical.

[0040] Reference Figure 1 and Figure 2 A detection camera 9 is provided on any stand 12, and the detection camera 9 is electrically connected to the controller. The detection end of the detection camera 9 faces the placement position 2, and the detection end of the detection camera 9 is facing the touch screen. The detection cameras 9 have independent numbers, and the number of numbers corresponds to the number of placement positions 2 one by one.

[0041] Specifically, the controller is a controller of a test device in a test area, which may be a computer with a dedicated detection application installed in the computer, capable of observing the working status of the test device in real time. Its specific composition and working principle are not described in detail here.

[0042] Furthermore, the detection cameras 9 are distinguished by numbers. For example, if there are fifteen placement positions 2 on the sliding carrier 1, the detection cameras 9 located in the fifteen placement positions 2 are numbered one to fifteen respectively. At this time, the detection status of the touch screen in the current placement position 2 by any one of the detection cameras 9 from one to fifteen can be observed on the controller. When any one of the detection cameras 9 detects that the touch screen has problems such as bad pixels, the operator can directly observe the specific position of the current touch screen through the controller, so as to quickly remove the unqualified touch screen along the placement position 2.

[0043] Correspondingly, an angle adjustment member 10 is provided on the stand 12. The angle adjustment member 10 may be a universal ball head seat or a ratchet adjustment seat. The base of the detection camera 9 is fixedly connected to the adjustment end of the angle adjustment member 10 to facilitate adjustment of the inclination angle of the detection camera 9 along the stand 12, so that the detection camera 9 can meet the detection requirements of touch screens of different sizes, thereby allowing the detection camera 9 to always be facing the touch screen.

[0044] In addition, the detection cameras 9 are all connected to the main line 3, and the detection cameras 9 are powered by the main line 3. The detection cameras 9 are conventional screen detection components, and their specific composition and working principle are not described here.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
