The support assembly 200 can be a nearly U-shaped support frame, the receiving groove 201 provided on the top of the support assembly 200 is recessed towards the workbench 100, on the one hand, the receiving groove 201 can provide a receiving environment for the middle frame in the groove depth direction, which is conducive to realizing the light leakage of the adhesion part of the middle frame and the glass backboard, and the inner side part top surface of the receiving groove 201 can support and abut the glass backboard, so that the stress of the middle frame module is more uniform, the middle frame module is leveled, thereby improving the stability and reliability of the middle frame module and improving the light leakage detection accuracy; on the other hand, the receiving groove 201 can also be used to receive the light source 300, realizing the dustproof and waterproof protection and mechanical protection of the light source 300, and at the same time, providing a relatively closed environment for the light source 300 to prevent light pollution and light interference, improve the light leakage detection accuracy and improve the light leakage detection effect. The light source 300 can be an LED light bar which can be adhered in the receiving groove 201 by adhesive or the like, for example, the LED light bar can be bonded at the inner side bottom corner of the receiving groove 201 by glue, so that it can face the adhesion part of the middle frame and the glass backboard as much as possible, improving the light utilization rate and the light leakage detection efficiency.

[0034] In an example, a switch piece 700 is further included, which is provided on the workbench 100 and can be electrically connected with the light source 300 through a cable, so as to control the opening and closing and brightness of the light source 300, thereby reducing energy consumption and improving energy utilization.

[0035] In a possible implementation, as shown in Figure 2 and Figure 3 , the support assembly 200 includes a first support 210 and at least two second supports 220, the first support 210 is arranged on the workbench 100, and the two second supports 220 are arranged at two ends of the first support 210 respectively, the first support 210 is provided with a first groove body, and the first groove body is used for accommodating at least a first side of the middle frame, the second support 220 is provided with a second groove body, the second groove body is communicated with the corresponding first groove body, and the second groove body is used for accommodating a second side of the middle frame, wherein the second side is arranged adjacent to the first side.

[0036] In the embodiment, the specific configuration of the support assembly 200 is optimized. Specifically, the support assembly 200 is configured as a combined component including at least the first support 210 and the at least two second supports 220, the first support 210 can be a nearly U-shaped frame, the first groove body arranged on the first support 210 includes a middle groove body extending along the first side and two side edge groove bodies arranged on both sides of the middle groove body and communicated with the middle groove body, and the middle groove body is used for accommodating the first side of the middle frame. The second support 220 can be a straight strip frame, and the second support 220 is provided with a second groove body communicated with the corresponding side edge groove body, and the second groove body is used for accommodating the second side of the middle frame. In this way, when the middle frame module is placed on the support assembly 200, at least three sides of the middle frame are accommodated in the first groove body and the second groove body, and at least three sides of the edge of the glass backboard are supported by the top surface inside the receiving groove 201.

The support assembly 200 provided in the example has a split structure, low processing difficulty, and high assembly flexibility.

[0037] In a possible implementation, as shown in Figure 2 , the second support 220 is movably arranged on the workbench 100 and forms a mortise and tenon joint with the first support 210, and the support assembly 200 further includes a first adjusting member 230, the first adjusting member 230 is arranged between the first support 210 and the second support 220, and is used for adjusting the total length of the groove body accommodating the second side in the extension direction of the second side.

[0038] In this embodiment, the specific configuration of the support assembly 200 is further optimized. Specifically, the support assembly 200 is configured as a combined member including at least the first support 210, at least two second supports 220, and a first adjusting member 230. The first adjusting member 230 can be an adjusting screw / bolt, which is threadedly connected to the second support 220 and has an inner end abutting against the sidewall of the first support 210. In this way, the total length of the slot body accommodating the second edge can be adjusted. When it is necessary to increase the total length of the slot body on the side, the first adjusting member 230 is loosened first to release the force constraint of the first support 210, then the second support 220 is moved outward to a specified position, and finally the first adjusting member 230 is tightened and the inner end of the first adjusting member 230 abuts against the first support 210 to achieve the connection and fastening of the second support 220 and the first support 210, thereby completing the adjustment of the total length of the slot body on the side.

[0039] In one possible implementation, as shown in Figure 2 and Figure 5 The first support 210 includes a second adjusting member 211 and two support blocks 212. The support blocks 212 are movably arranged on the workbench 100, and the second adjusting member 211 is arranged between the two support blocks 212 and used to adjust the total length of the slot body accommodating the first edge in the extension direction of the first edge.

Specifically, the first support 210 is configured as a combined member including at least the second adjusting member 211 and two support blocks 212, which can be right-angle frames and form a mortise and tenon joint therebetween. The second adjusting member 211 can be an adjusting screw / bolt, which is threadedly connected to one of the support blocks 212, and the inner end thereof is used to abut against the side wall of the other support block 212, so as to adjust the total length of the slot body of the first side. When it is needed to increase the total length of the slot body of the side, the second adjusting member 211 is first loosened to release the force constraint of the two support blocks 212, and then one of the support blocks 212 is moved outward to a specified position, or the two support blocks 212 are simultaneously moved outward to specified positions, and finally the second adjusting member 211 is tightened and the inner end thereof is abutted against the other support block 212 to achieve the connection and fastening of the two support blocks 212, and the adjustment of the total length of the slot body of the side is completed. When it is needed to reduce the total length of the slot body of the side, one of the support blocks 212 is moved inward or the two support blocks 212 are simultaneously moved inward, and the remaining operations are the same as above, which will not be described in more detail. The support assembly 200 provided in this example can at least adjust the total length of the slot body of the first side in the extension direction of the first side, and has a greater length accommodation degree for the first side of the middle frame module, and can be adapted to middle frame modules of more sizes, and has a wide application range.

[0041] In a possible implementation manner, as shown in Figure 2 the support assembly 200 further includes a first reinforcing member 240, both ends of the first reinforcing member 240 are connected with both ends of the first support 210, and / or the support assembly 200 further includes a second reinforcing member 250, both ends of the second reinforcing member 250 are connected with the two second supports 220.

[0042] In this embodiment, the specific configuration of the support assembly 200 is further optimized. Specifically, the support assembly 200 is configured as a combined member including at least the first support 210, the at least two second supports 220, and the first reinforcing member 240 and / or the second reinforcing member 250. The first reinforcing member 240 can be a columnar rod, which can be connected on both ends of the first support 210 by welding, so as to improve the shape stability and reliability of the first support 210 and improve the structural strength of the first support 210. The second reinforcing member 250 can be a columnar rod, which can be connected between the two second supports 220 by welding, so as to constrain the opening degree of the two second supports 220, improve the shape stability of the second support 220, and improve the structural strength of the support assembly 200. The support assembly 200 provided in this example has stable structure, great strength and strong reliability.

[0043] In a possible implementation manner, as shown in Figure 4As shown, in the groove width direction of the accommodation groove 201, the support assembly 200 comprises a first support part 261, a second support part 262 and a third support part 263 arranged in sequence from inside to outside; in the groove depth direction of the accommodation groove 201, the first support part 261 protrudes out of the third support part 263, and the third support part 263 protrudes out of the second support part 262, so as to enclose the accommodation groove 201.

[0044] In this embodiment, the specific configuration of the support assembly 200 is optimized. Specifically, the support assembly 200 is configured as a combined component comprising at least the first support part 261, the second support part 262 and the third support part 263, which are integrally formed and form a U-shaped frame in the groove width direction, and the top part thereof forms a U-shaped accommodation groove 201 in the direction. The first support part 261 is used to support the glass backboard, the second support part 262 is used to support the light source, and the third support part 263 is used to support the middle frame. Moreover, the height of the second support part 262 in the middle is less than the height of the first support part 261 and the second support part 262, so as to reserve sufficient operation space for the light source, which can effectively avoid the interference of the glass backboard with the operation of the light source; at the same time, the height of the third support part 263 on the outer side is less than the height of the first support part 261 on the inner side, so as to reserve the thickness accommodation space of the middle frame in the groove depth direction, and at least the middle frame assembly in the groove width direction is subjected to two groups of support forces, one of which is the force support of the middle frame by the third support part 263, and the other of which is the force support of the glass backboard by the first support part 261, thereby improving the force balance of the middle frame assembly, making the middle frame module placed on the support assembly more stable and reliable, and facilitating subsequent light leakage detection. The support assembly 200 provided in this example has stronger support stability and reliability for the middle frame module, and more accurate light leakage detection.

[0045] In an example, the third support part 263 is provided with an accommodation internal corner 264, which is arranged at the top end of the third support part 263 and faces the first support part 261. The accommodation internal corner 264 is in communication with the accommodation groove 201 and is used to accommodate the external corner of the middle frame, which can not only realize the alignment and limiting of the middle frame and provide the assembly accuracy of the middle frame module, thereby shortening the assembly time, but also can ensure that the light source can only escape from the gap at the bonding position of the middle frame and the glass backboard, thereby improving the reliability of the detection result.

[0046] In a possible implementation manner, as shown in Figure 4 The lamp source 300 is inclinedly arranged in the accommodation groove 201 through the cushion block 400.

[0047] In the embodiment, the light leakage detection device is configured as a combined component including at least the workbench 100, the support assembly 200, the light source 300, and the cushion block 400. The cushion block 400 can be a right triangular prism adhesive tape, which can be attached to the inner side bottom corner of the accommodating groove 201 by hot melt adhesive to provide a mounting environment for the light source 300. In this way, the light source can irradiate the bonding position of the middle frame and the glass back plate, thereby improving the light utilization rate and the light leakage detection accuracy and efficiency.

[0048] In a possible implementation, as shown in Figure 1 the telescopic assembly 500 is further included and can be telescopically arranged below the workbench 100 to adjust the working height of the workbench 100.

[0049] In the embodiment, the light leakage detection device is configured as a combined component including at least the workbench 100, the support assembly 200, the light source 300, and the telescopic assembly 500. The telescopic assembly 500 can be a telescopic rod structure, which can be connected below the workbench 100 by fasteners such as screws / bolts to raise or lower the workbench 100 to meet the different height requirements of the workers and improve the application range of the light leakage detection device.

[0050] In an example, the telescopic assembly 500 includes four telescopic members, which include the fixed rod 510, the telescopic rod 520, and the third adjusting member 530. One end of the telescopic rod 520 is fixedly connected with the workbench 100, and the other end is telescopically embedded in the top end of the fixed rod 510. The lower end of the fixed rod 510 is used to contact the ground. The third adjusting member 530 is arranged between the fixed rod 510 and the telescopic rod 520 to adjust and fix the relative position between the fixed rod 510 and the telescopic rod 520. For example, the third adjusting member 530 can be an adjusting screw / adjusting bolt, which is threadedly connected to the fixed rod 510 and used to abut against the side wall of the telescopic rod 520. In this way, the total length of the telescopic rod 520 and the fixed rod 510 can be adjusted. When the workbench 100 needs to be raised, the third adjusting member 530 is loosened to release the force constraint between the fixed rod 510 and the telescopic rod 520. Then, the telescopic rod 520 is pulled out upward to a specified height. Finally, the third adjusting member 530 is tightened to abut against the telescopic rod 520 and form a force constraint between the fixed rod 510 and the telescopic rod 520 to realize height locking of the telescopic member. When the workbench 100 needs to be lowered, the operation is the same as above, which will not be described in detail here.

[0051] In a possible implementation, as shown in Figure 1 and Figure 2 the roller assembly 600 is further included and can be rotatably arranged on the side of the telescopic assembly 500 away from the workbench 100.

[0052] In the embodiment, the light leakage detection device is configured as a combined component including at least the workbench 100, the support assembly 200, the light source 300, the telescopic assembly 500, and the roller assembly 600. The roller assembly 600 is arranged at the bottom of the telescopic assembly 500 and can drive the telescopic assembly 500 and the workbench 100 to move on the ground, saving time and effort and facilitating transfer. For example, but not limited to, the roller assembly 600 includes four rollers, each of which is arranged below a telescopic piece to at least improve the transfer convenience of the light leakage detection device in terms of quantity.

[0053] In a possible implementation, a light-emitting piece (not shown in the figure) is further included and arranged at the outer periphery of the support assembly 200. The light-emitting piece can be a U-shaped plate which can be arranged vertically on the workbench 100 and used to emit light through the gap at the bonding position of the middle frame and the glass back plate. In this way, the operator can clearly observe the light leakage of the middle frame module from any angle, which is more convenient.
