DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] For example 1, please refer to Figure 1-Figure 2 , an LCD liquid crystal display screen, including an LCD liquid crystal screen 200, the LCD liquid crystal screen 200 includes a housing 210, and a liquid crystal panel 211 and a backlight module 212 are provided on the housing 210; The housing 210 is further provided with a battery compartment 220 , which is used to supply power to the backlight module 212 so as to enable the liquid crystal panel 211 to form an image.

[0033] The battery compartment 220 is provided with a positive electrode interface 221 and a negative electrode interface 222, and the negative electrode interface 222 is provided with a first spring 223. The positive electrode interface 221 and the negative electrode interface 222 are both connected to a first wire 224, and the two first wires 224 are both connected to a plug 225. The battery compartment 220 is provided with a compartment cover 226.

[0034] In this embodiment, the light guide plate in the backlight module 212 is a key component. It efficiently converts a line light source into a surface light source through a sophisticated light guide point design, thereby providing uniform backlight for the liquid crystal panel 211 .

[0035] The liquid crystal panel 211 is constructed by sandwiching a liquid crystal cell between two parallel glass substrates. Thin-film transistors (TFTs) are arranged on the lower glass substrate, while color filters are placed on the upper glass substrate. By manipulating the signals and voltages on the TFTs, the orientation of the liquid crystal molecules is altered, thereby controlling the polarized light emitted from each pixel and achieving the desired display effect.

[0036] After the battery 300 is placed in the battery compartment 220 , power is supplied to the backlight module 212 .

[0037] For example 2, please refer to Figure 3-10 An LCD display screen and its detection device include a workbench 100, on which a detection mechanism 400 is provided for performing voltage detection on a battery compartment 220. The detection mechanism 400 includes a multimeter 410 and two sockets 420 provided on the workbench 100. The multimeter 410 and the two sockets 420 are electrically connected.

[0038] The workbench 100 is also provided with a transport mechanism 500 and an installation mechanism 600. The transport mechanism 500 is used to transport the LCD screen 200 to the detection mechanism 400, and the installation mechanism 600 is used to install the battery 300 on the battery compartment 220 and to install the two plugs 225 on the two sockets 420 respectively.

[0039] The transport mechanism 500 includes two conveying rollers 510 rotatably disposed on the workbench 100 , and a conveying belt 520 is disposed on the two conveying rollers 510 .

[0040] A first insulating seat 530 is provided on the conveyor belt 520, and the LCD screen 200 is movably connected to the first insulating seat 530. Two slides 540 are symmetrically slidably provided on the first insulating seat 530. Both slides 540 are provided with elastic sockets 550. The two plugs 225 are respectively movably connected to the two elastic sockets 550. The two slides 540 are connected by a connecting rod 560.

[0041] In this embodiment, driving one conveyor roller 510 to rotate drives the other conveyor roller 510 to rotate, causing the conveyor belt 520 to move from the front to the back or vice versa. A first insulating base 530 is fixedly mounted on the conveyor belt 520. A slot shaped to fit the LCD screen 200 is defined in the middle of the upper end of the first insulating base 530. The LCD screen 200 is positioned in this slot to secure it relative to the workbench 100.

[0042] Slide plates 540 are slidably mounted on both the left and right sides of the first insulating seat 530 , and elastic clamping seats 550 fixed on the slide plates 540 can be used to clamp the plug 225 . The two slide plates 540 are fixed by a connecting rod 560 .

[0043] After the LCD screen 200 is installed, the transport mechanism 500 transports the LCD screen 200 to the battery 300 and the testing mechanism 400, which are located in the same vertical position. The standardized, intact, and quality-free battery 300 is then installed in the battery compartment 220 using the installation mechanism 600. The two first wires 224 are then moved upward to insert the two plugs 225 into the two sockets 420 slidably mounted on the workbench 100. The two sockets 420 are electrically connected to the multimeter 410, forming a circuit. The battery compartment 220 circuit can then be tested by checking whether the current and voltage measured by the multimeter 410 meet the standards.

[0044] It is necessary to add that Figure 3-Figure 5 The LCD screen 200 and battery compartment 220 shown here are for ease of illustration and do not represent the actual product dimensions. Similarly, the connectors of the two first wires 224 can be positioned at corresponding locations on the first insulating base 530 so that when the LCD screen 200 is placed on the first insulating base 530, the connectors of the two first wires 224 automatically contact the positive and negative terminals of the battery compartment 220.

[0045] For details, please refer to Example 3 Figure 3-10 The mounting mechanism 600 includes a first slider 610 slidably arranged on the workbench 100, a second insulating seat 620 is rotatably arranged on the first slider 610, the battery 300 is arranged on the second insulating seat 620, and the positive and negative poles of the battery 300 correspond to the positive electrode interface 221 and the negative electrode interface 222 respectively.

[0046] The mounting mechanism 600 further includes a fourth spring 630 , the two ends of which are respectively connected to the first slider 610 and the second insulating seat 620 . The elastic force of the fourth spring 630 tilts the second insulating seat 620 toward the negative electrode interface 222 .

[0047] The mounting mechanism 600 further includes a second fixing block 640 disposed on one of the slides 540 . A second sliding block 650 is slidably disposed on the workbench 100 . The first sliding block 610 and the second sliding block 650 are reversely driven by a transmission assembly 660 .

[0048] The transmission assembly 660 includes a first rotating rod 661 rotatably disposed on the workbench 100 , and a connecting plate 662 is disposed on the first rotating rod 661 .

[0049] A first connecting seat 663 is provided on the first slider 610 , a second connecting seat 664 is provided on the second slider 650 , and two sliding grooves 665 are symmetrically provided on the connecting plate 662 . The first connecting seat 663 and the second connecting seat 664 are slidably provided in the two sliding grooves 665 respectively.

[0050] In this embodiment, in order to realize automatic installation of the battery 300 and the two plugs 225 and solve the problem that when the battery 300 is automatically installed, the limiting function of the first spring 223 is set too long, and the battery 300 may be stuck and cannot be installed correctly when directly inserted.

[0051] A first slider 610 is installed in the middle of the workbench 100 for sliding up and down. A second insulating seat 620 is rotatably installed on the inner wall of the first slider 610. The second insulating seat 620 is elastically connected to the first slider 610 through a fourth spring 630, and the battery 300 is fixed at the lower end of the second insulating seat 620.

[0052] By moving the first slider 610 downward, the battery 300 can be aligned and inserted into the battery compartment 220, and the elastic force of the fourth spring 630 makes the battery 300 tilted, so that the negative pole of the battery 300 is first inserted into the battery compartment 220 and contacts the first spring 223. The first slider 610 continues to descend, and the positive pole of the battery 300 is then inserted into the battery compartment 220 and connected with the positive pole interface 221. The battery 300 and the second insulating seat 620 are rotated to push the first spring 223 to the left. By simulating the normal manual installation of the battery 300, the jamming problem caused by directly inserting the battery 300 is avoided.

[0053] When the second slider 650 slidably mounted on the workbench 100 moves upward, it pushes the elastic holder 550 fixed on the slide 540 , thereby driving the two slides 540 and the two plugs 225 to move upward, and the two plugs 225 are inserted into the two sockets 420 .

[0054] The movement of the first slider 610 and the second slider 650 is driven by the transmission assembly 660. The rotation of the first rotating rod 661 drives the connecting plate 662 fixed on its surface to rotate. At this time, the first connecting seat 663 and the second connecting seat 664 fixed on the first slider 610 and the second slider 650 move inward along the two sliding grooves 665, so that the first slider 610 moves downward and the second slider 650 moves upward.

[0055] For details, please refer to Example 4. Figure 3-10 The detection mechanism 400 also includes two electromagnets 430 symmetrically arranged on the workbench 100 . The two electromagnets 430 are both provided with a second wire 440 and a third wire 450 . The two second wires 440 are respectively connected to the two sockets 420 , and the two third wires 450 are both connected to the multimeter 410 .

[0056] The two sockets 420 are both slidably disposed on the workbench 100 . The detection mechanism 400 further includes two second springs 460 and two automatic pop-up components 470 symmetrically disposed on the workbench 100 .

[0057] One end of the two second springs 460 is connected to the two sockets 420 respectively, and the other ends of the two second springs 460 are connected to the workbench 100. The two automatic pop-up components 470 are used to pop out the two sockets 420 when a short circuit occurs after the battery compartment 220 is powered on.

[0058] The automatic pop-up assembly 470 includes a magnet 471 and two third springs 472 . Two ends of the two third springs 472 are connected to the magnet 471 and the workbench 100 , respectively.

[0059] Two rotating plates 473 are provided on the magnetic block 471 , and two first fixing blocks 474 are symmetrically provided on the socket 420 . The two rotating plates 473 are respectively adapted to the two first fixing blocks 474 .

[0060] In this embodiment, when a short circuit or other fault occurs in the LCD screen 200 , since the current is relatively large during a short circuit, it is necessary to avoid damaging the device and causing fire.

[0061] After the battery 300 is installed on the LCD screen 200, a circuit is formed. Normally, the socket 420 is elastically connected to the workbench 100 via the second spring 460, maintaining a relatively fixed position. When the electromagnet 430 is energized, it generates magnetism, and the magnetism on the side of the electromagnet 430 closest to the magnetic block 471 is opposite to the magnetism on the side of the magnetic block 471 closest to the electromagnet 430. When the circuit is normally formed, the combined force of the magnetic field strength of the electromagnet 430 on the magnetic block 471 and the elastic force of the two third springs 472 is insufficient to pull the magnetic block 471, causing the two rotating plates 473 to be positioned below the two first fixed blocks 474.

[0062] When a short circuit occurs in the LCD screen 200, the instantaneous current increases, the magnetic field strength generated by the electromagnet 430 increases, and the suction force on the magnetic block 471 increases, causing the magnetic block 471 to move upward. At this time, the two rotating plates 473 fixed on the magnetic block 471 push the two first fixed blocks 474 and then drive the socket 420 to move upward, thereby disconnecting from the plug 225 and cutting off the power.

[0063] For details, please refer to Example 5. Figure 3-10 The workbench 100 is also provided with a driving mechanism 700 for driving the transport mechanism 500 and the installation mechanism 600 to operate intermittently.

[0064] The driving mechanism 700 includes a first intermittent rotating assembly 710 , a second intermittent rotating assembly 720 and a driving assembly 730 .

[0065] The first intermittent rotating assembly 710 includes a second rotating rod 711 rotatably disposed on the workbench 100 . A first half gear 712 is disposed on the second rotating rod 711 . A first spur gear 713 is disposed on one of the conveying rollers 510 , and the first spur gear 713 meshes with the first half gear 712 .

[0066] The second intermittent rotating assembly 720 includes a third rotating rod 721 and a fourth rotating rod 723 rotatably arranged on the workbench 100, the third rotating rod 721 is provided with a second spur gear 722, the fourth rotating rod 723 is provided with a second half gear 724, and the second half gear 724 is engaged with the second spur gear 722, the first rotating rod 661 is provided with a third spur gear 725, and the second spur gear 722 and the third spur gear 725 are provided with a toothed belt 726.

[0067] The driving assembly 730 includes a motor 731 arranged on the workbench 100, the output shaft of the motor 731 is connected to the fourth rotating rod 723, the fourth rotating rod 723 is provided with a first bevel gear 732, the second rotating rod 711 is provided with a second bevel gear 733, and the second bevel gear 733 is engaged with the first bevel gear 732.

[0068] In this embodiment: the motor 731 installed on the workbench 100 is driven to rotate the fourth rotating rod 723 installed on the workbench 100 and the first bevel gear 732 fixed on the fourth rotating rod 723, and the first bevel gear 732 then drives the second rotating rod 711 installed on the workbench 100 and the second bevel gear 733 fixed on the second rotating rod 711 to rotate.

[0069] First, the second rotating rod 711 rotates, driving the first half gear 712 fixed to the second rotating rod 711 to rotate. The first half gear 712 is then meshed with the first spur gear 713. The rotation of the first spur gear 713 then drives one of the conveying rollers 510 to rotate, thereby transporting the battery compartment 220 backward. At this time, the second half gear 724 is not meshed with the second spur gear 722.

[0070] Then, when the first half gear 712 rotates to disengage from the first spur gear 713, the battery compartment 220 stops. At this time, the second half gear 724 rotates to engage with the second spur gear 722, and the third rotating rod 721 and the second spur gear 722 fixed on the third rotating rod 721 rotate. Through the transmission of the toothed belt 726, the third spur gear 725 fixed on the first rotating rod 661 is driven to rotate, and then the first rotating rod 661 is driven to rotate. The first rotating rod 661 rotates to move the battery 300 down and install it in the battery compartment 220, and move the two plugs 225 up and insert them into the two sockets 420.

[0071] After the inspection is completed, the second half gear 724 disengages from the second spur gear 722, allowing the first slider 610 and the second slider 650 to return to their original position under the action of gravity. The second slider 650 is heavier than the first slider 610. It should be noted that a spring can be added to elastically connect the first slider 610 and the second slider 650 to the workbench 100 to increase the power of the return.

[0072] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0073] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
