Detailed Implementation

[0016] The present invention will be further described below with reference to embodiments and accompanying drawings: like Figure 1-3 As shown, a fault-prevention mechanism for a core component of a seat backrest mainly consists of a control box 10, a workbench 40, a tray 30, a marking and moving component 50, a photo marking device 60, a tray moving component 70, an alarm light 80, and a control system.

[0017] The workbench is positioned above the control box 10. A tray 30 holds the angle adjuster 20. A photographic marking device 60 is mounted on the rear of the workbench 40 via a marking moving assembly 50. Preferably, the marking moving assembly 50 is a three-axis moving assembly, meaning the photographic marking device can move forward, backward, left, right, and up and down via the marking moving assembly 50. However, depending on the installation position of the angle adjuster on the tray, the marking moving assembly 50 can also be a left-right moving assembly, a tray moving assembly, or a combination of both. Because of the marking moving assembly, marking can be performed on each angle adjuster even when multiple angle adjusters are placed on the tray. The photographic marking device utilizes existing technology.

[0018] To accommodate the corner adjuster on the pallet, the pallet 30 includes a pallet base plate 31, on which at least one set of positioning components for placing the corner adjuster is provided. The positioning components include three positioning posts 32 disposed on the pallet base plate 31. Each positioning post 32 has a positioning pin 33 at its upper end, which can be inserted into the corner adjuster hole. The outer diameter of the positioning post 32 is larger than the outer diameter of the positioning pin 33; preferably, the upper end of the positioning pin is tapered. To facilitate pallet movement, handles 34 are provided on both the left and right sides of the pallet base plate 31.

[0019] To facilitate the movement of the pallet into the working area of ​​the photo-marking equipment, a pallet moving assembly 70 is provided on the worktable 40 to drive the pallet 30 back and forth. The pallet moving assembly 70 includes a front and rear drive assembly and a front and rear moving block 71. At least two mounting posts 72 are provided on the front and rear moving block 71 for pallet installation and positioning. Mounting holes for inserting the mounting posts are correspondingly provided on the pallet bottom plate. Preferably, the upper end of the mounting post is tapered.

[0020] Since a photo marking device is installed, a light shield 41 is provided on the workbench 40 to cover the marking moving component and the photo marking device for easy light protection. An adhesive strip 42 is provided on the lower front side of the light shield 41. The adhesive strip facilitates the tray to move through the light shield and into the working area of ​​the photo marking device under the action of the tray moving component.

[0021] To visually indicate whether there are any errors in the parts placed on the tray, an alarm light 80 is installed above the light shield. To facilitate tray placement, a placement platform 45 is provided on both the left and right sides of the front of the workbench 40, one side for placing trays that have not met the standards, and the other side for placing trays that have been marked.

[0022] To ensure safe startup, two start buttons 43 are provided on the front side of the workbench 40, spaced apart on the left and right, so that the entire mechanism must be started simultaneously by the two start buttons. An emergency stop button 44 is provided next to either start button 43.

[0023] In this embodiment, the moving component adopts a motor lead screw moving module. To facilitate the control of the entire mechanism, a control system is set in the control box, and an interactive operation screen 90 is also embedded in the front of the light shield 41. The operation screen is used for inputting the correct angle adjustment photo, marking code, etc., and outputting the process of taking pictures and marking the equipment. The marking moving component, tray moving component, alarm light, operation screen, emergency stop button, and start button are all electrically connected to the control system. The control system adopts existing technology with information receiving, information processing, and information sending functions, and the operation screen also adopts existing technology.

[0024] During operation, the marking number and correct photo are pre-entered into the operation screen. Simultaneously, the angle adjuster is placed on the tray, which is then placed on the tray moving assembly. The start button is pressed, causing the tray moving assembly to move the tray backward into the area of ​​the photo-marking device. The photo-marking device takes a picture of the angle adjuster on the tray and compares it with the correct part. If the part is correct, marking is complete; otherwise, an alarm is triggered. To ensure that all parts on each tray are marked, the photo-marking device is moved by the marking moving assembly. After all parts are marked, the photo-marking device returns to its original position, and the tray returns to its original position under the tray moving assembly. Throughout the entire photo-marking process, the sequence of the photo-marking devices is fixed, such as moving from left to right.
