Abstract
Description
Technical Field
[0001] This utility model belongs to the field of LED module production technology, specifically an LED module turnover cart. Background Technology
[0002] In the LED display industry, especially with the rapid rise of Mini / Micro-LED technology, LED modules, as the core unit for backlighting or direct-view displays, involve complex production processes, frequent transfers, and are extremely sensitive to cleanliness, electrostatic discharge, and mechanical shock. Currently, the industry commonly uses "layer-by-layer lathes" as the transfer equipment for modules between various processes.
[0003] Traditional multi-layer LED carts have a relatively simple structure, typically consisting of a frame welded from steel profiles, providing a stable support structure for the entire vehicle. Inside the frame, dozens of metal or plastic partitions are fixed at equal intervals along the height, stacked layer upon layer to form a "thousand-layer" structure for holding LED modules. Four swivel casters are installed at the bottom, allowing for manual movement of the cart by pushing or pulling. While this structure is simple and inexpensive, it has significant drawbacks in practical applications: the LED beads on the LED modules are the core components for light emission and are extremely fragile. During transport using traditional multi-layer carts, due to the lack of a buffer layer, when the cart is subjected to vibration or collision, the metal or rigid plastic partitions come into direct, rigid contact with the LED modules, and the resulting impact force is transmitted to the LED beads without any attenuation. Under such severe impact, the LED beads are highly susceptible to cracking. Once the LED beads are damaged, the display function of the entire LED module will be severely affected, potentially leading to localized display abnormalities or even complete failure. This increases the defect rate and production costs. In addition to LED chip breakage and gold wire breakage, traditional multi-layer carts lacking a buffer layer may also damage other components of the LED module during transportation, such as chip detachment and circuit board deformation. These damages directly affect the overall performance of the LED module, leading to problems such as uneven brightness, color deviation, and shortened lifespan. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. It should be noted that the drawings are schematic and not illustrated to scale. For clarity and convenience, the relative sizes and proportions of the parts shown in the drawings have been exaggerated or reduced in size. Any size is only illustrative and not limiting.
[0030] Example 1:
[0031] refer to Figure 1 as well as Figures 3 to 7 This utility model provides an LED module turnover cart, comprising:
[0032] Track 1, with an electric drive mechanism 2 slidably mounted on the upper end of track 1;
[0033] The support plate 3 is installed on the upper end of the electric drive mechanism 2. It is driven by the electric drive mechanism 2 and moves along the track 1. Four columns 4 are vertically installed on the upper surface of the support plate 3. Several shafts 6 are rotatably installed between two adjacent columns 4 through several bearings. Horizontal frames 7 are installed on the outer surface of several shafts 6. Two legs 13 are installed at the lower end of several horizontal frames 7. When the horizontal frames 7 are in a flat state, the legs 13 form a surface contact support with the upper surface of the lower horizontal frame 7.
[0034] The tray 8 is installed on the upper end of the horizontal frame 7. The upper end of the tray 8 has a vertical groove 9, and several grooves 9 are used to accommodate the side-mounted LED module.
[0035] Intelligent control component 16 is installed on the upper end of support plate 3. Intelligent control component 16 is electrofused to electric drive mechanism 2 and is configured to control movement path and start / stop.
[0036] The power supply component 17 is mounted on the upper end of the support plate 3 and is used to provide power to the electric drive mechanism 2 and the intelligent control component 16.
[0037] The support plate 8 is made of anti-collision cotton. Connecting plates 10 are installed on both sides of the horizontal frame 7, and connecting plates 12 are installed on both adjacent columns 4. Telescopic components 11 are rotatably installed between the connecting plates 10 and the connecting plates 12. The telescopic components 11 are pneumatic cylinders or electric push rods.
[0038] All four columns 4 have cushioning pads 5 on their outer surfaces, and several horizontal frames 7 have protective plates 14 at their lower ends. Top guard plates 15 are movably inserted into the tops of the four columns 4. The cushioning pads 5, protective plates 14, and top guard plates 15 are all made of impact-resistant cotton. The impact-resistant cotton is made of EVA impact-resistant cotton.
[0039] Detailed implementation: The operator tilts the horizontal frame 7 by rotating it. During this process, the telescopic component 11 is rotatably connected between the connecting plate 10 on the side of the horizontal frame 7 and the connecting plate 12 on the column 4, providing auxiliary support and aiding in positioning.
[0040] The operator then inserts the LED module upright into the vertical groove 9 on the tray 8. Since the tray 8 is made of EVA anti-collision cotton, it effectively protects the LED module from collisions and scratches during placement and transportation. It effectively protects the LED chips and other components, preventing damage during handling. After the LED module is installed, when the horizontal frame 7 is placed horizontally, its two lower legs 13 rest stably on the upper surface of the adjacent lower horizontal frame 7, forming surface contact support. This ensures the stability and levelness of the frame under load. Furthermore, the protective plate 14 at the bottom and the top protective plate 15 further protect the upper part of the groove 9, reducing damage caused by displacement due to shaking during handling. The entire structural design, combined with multiple EVA anti-collision cotton components, provides multi-directional cushioning protection for the LED module during transportation.
[0041] The operator sets the target position or movement path through the intelligent control unit 16. The intelligent control unit 16 receives the command and prepares to control the movement, sending a drive signal to the electric drive mechanism 2. The power supply unit 17 provides power to the electric drive mechanism 2 and the intelligent control unit 16. The electric drive mechanism 2 starts, driving the entire device to slide along the laid track 1, moving the support plate 3, all structures mounted on it, and the LED modules together to the target workstation.
[0042] Example 2:
[0043] refer to Figures 1 to 7This utility model provides an LED module turnover cart, comprising:
[0044] Track 1, with an electric drive mechanism 2 slidably mounted on the upper end of track 1;
[0045] Support plate 3 is mounted on the upper end of electric drive mechanism 2 and is driven by electric drive mechanism 2 to move along track 1;
[0046] The intelligent control component 16 is installed on the upper end of the support plate 3. The intelligent control component 16 is electrically connected to the electric drive mechanism 2 and is configured to control the movement path and start / stop.
[0047] The power supply component 17 is mounted on the upper end of the support plate 3 and is used to provide power to the electric drive mechanism 2 and the intelligent control component 16.
[0048] The electric drive mechanism 2 includes several movable frames 21 slidably mounted on the upper end of the track 1. Several movable wheels 22 are rotatably mounted on the lower end of each movable frame 21, and each movable wheel 22 is rotatably connected to the track 1. Drive wheels 23 are rotatably mounted inside each movable frame 21 and are rotatably connected to the track 1. A drive component 24 is provided on one side of each movable frame 21 to drive the drive wheels 23 to rotate. A support base 25 is rotatably mounted on the upper end of each movable frame 21, and the upper end of the support base 25 is connected to the lower end of the support plate 3. The drive component 24 may be a stepper motor.
[0049] The intelligent control unit 16 includes a central controller 161 mounted on the upper end of the support plate 3. The central controller 161 is equipped with a path navigation module and a wireless communication module. The path navigation module is used to plan the movement path based on the track 1 and output drive commands to the electric drive mechanism 2. The wireless communication module receives external scheduling commands.
[0050] The central controller 161 has a control panel 162 and a button group 163 at the front end. The button group 163 includes a start button, an emergency stop button and a station selection button. The signal line of the button group 163 is connected to the interface of the central controller 161.
[0051] The power supply unit 17 includes a battery compartment 171 located on the upper end of the support plate 3. One end of the battery compartment 171 is provided with a charging plug 172 and an infrared locator 173. An additional charging compartment is provided, and an infrared sensor is installed in the charging compartment. The charging compartment is provided with a flexible socket that matches the charging plug 172.
[0052] Detailed implementation: When starting the turnover vehicle, the target station is set through the control panel 162. The operator inputs commands through the button group 163, which includes start, emergency stop, and station selection buttons. The wireless communication module of the central controller 161 can also receive commands from the external scheduling system. The path navigation module generates a movement path based on the layout of the track 1 and outputs drive commands to the electric drive mechanism 2. The drive component 24 drives the drive wheel 23 to rotate, and the friction between the drive wheel 24 and the track 1 propels the moving frame 21 along the track 1. The moving wheel 22 at the lower end of the moving frame 21 assists in guidance and load-bearing to ensure smooth operation. The support base 25 rotatably connects the moving frame 21 and the support plate 3, adapting to the undulations of the track 1 to avoid rigid impact, according to the set target work station.
[0053] The battery compartment 171 contains a battery that powers the electric drive mechanism 2 and the intelligent control unit 16. When the vehicle needs to be recharged, the intelligent control unit 16 automatically plans a return path based on the current power threshold or task interval, guiding the electric drive mechanism 2 along the track 1 to the fixed charging compartment. When it approaches the charging pile, the infrared sensor is activated and forms a positioning with the infrared locator 173, and the auxiliary charging plug 172 is inserted into the elastic socket in the charging compartment. After the two are inserted, the external power supply charges the battery pack in the battery compartment 171 with constant current / constant voltage through the plug-socket circuit.
[0054] By integrating a battery-powered electric drive mechanism 2 at the bottom of the transfer cart, this solution replaces the traditional manual cart-pushing mode, reducing the need for dedicated handling personnel and significantly reducing labor intensity by replacing physical labor with electricity. Furthermore, the cart can be set to automatically drive into the target workstation; once all daily transfer tasks are completed, the cart automatically plans the shortest return-to-charging path based on its battery threshold, guiding the vehicle to the designated parking area and completing charging. Thus, while saving manpower, it ensures 24-hour uninterrupted equipment availability, further improving the overall cycle time and logistics efficiency of the LED production line.
