[0028] The assembly platform for organ protective cover manufacturing process aims to achieve efficient and precise organ protective cover assembly process through a series of innovative designs and technical improvements. The following are the main components of the platform and their working principles.

[0029] Overall structural principle

[0030] The assembly platform realizes multi-dimensional adjustment through the hierarchical mechanical structure of pedestal 1-base-slide rail-clamping mechanism, and completes the adaptive clamping and alignment of the protective cover assembly by combining the positive and negative screw drive device and the infrared positioning system.

[0031] Pedestal 1: As the basic bearing module, it has a guide rail 4 on the top for guiding the base to move along the X-axis.

[0032] Base: Composed of beam seat 2 and side seats 3 symmetrically arranged on both sides, it is driven by the positive and negative screw rod 14 of device one 7 to slide along the guide rail 4 of pedestal 1, realizing the overall width adjustment of the base.

[0033] Clamping mechanism: Divided into middle beam clamp 6 and side clamp 5, driven by the positive and negative screw rod 14 of device two 8 and device three 9 to move along the slide rail, realizing the adjustment of clamping distance in Y-axis direction; Middle beam clamp 6 is a frame column structure, and side clamp 5 is an L-shaped structure, with inside mounting holes 19 used for fixing the skeleton of organ protective cover through bolt structure.

[0034] Working principle of preferred technical solution

[0035] Positive and negative screw rod 14 synchronous drive system

[0036] Device one 7: Beam seat 2 is fixed at the middle position of positive and negative screw rod 14, and side seats 3 are sleeved at both ends; When the screw rod motor 13 starts, the side seats 3 move in reverse along the screw rod, synchronously expanding or shrinking the width of the base.

[0037] Device two 8 and device three 9: the middle beam clamp 6 and the side clamp 5 are respectively sleeved on the forward and reverse lead screws 14, and are driven to realize symmetrical clamping by the lead screw motor 13, so that the center line of the protective cover coincides with the center line of the base.

[0038] Infrared positioning calibration system

[0039] The infrared emitter 15 is arranged on the two sides of the middle beam clamp 6, and the infrared receiver 16 is arranged on the rear side of the side clamp 5; when the side clamp 5 moves to the preset position, the infrared signal is captured by the receiver, and the central controller 12 determines that the clamping mechanism is aligned and completed, and stops the lead screw motor 13 and locks the position.

[0040] Modular lifting device 11

[0041] The side clamp 5 and the middle beam clamp 6 adopt a two-section design, the lower half is fixed with the lifting cylinder 17, and the upper half is connected with the pneumatic telescopic rod of the lifting cylinder 17 through the jacking frame 18 to realize Z-axis height adjustment, which adapts to the pressing needs of protective covers of different thicknesses.

[0042] Control system logic

[0043] The central controller 12 executes the following processes:

[0044] Receive the size parameters of the protective cover, calculate the target position of the base and the clamping mechanism;

[0045] The driving device one 7 adjusts the width of the base to the target value;

[0046] Start device two 8 and device three 9 to move the middle beam clamp 6 and the side clamp 5, and the infrared system feedbacks the position deviation in real time;

[0047] Trigger the lifting device 11 to adjust the clamping height, and complete the pressing of the protective cover.

[0054] Step 2: Base width adjustment

[0055] The lead screw motor 13 of the device one 7 drives the positive and negative lead screws 14 to rotate, so that the side seat 3 is synchronously moved to the target width along the guide rail 4 of the base 1.

[0056] Step 3: Clamping mechanism positioning

[0057] The device two 8 and the device three 9 drive the middle beam clamp 6 and the side clamp 5 to move along the slide rail, and the infrared receiver 16 stops moving after capturing the signal, so as to ensure that the clamping center is aligned.

[0058] Step 4: Shroud fixing and interlayer assembly

[0059] The shroud base material is placed between the middle beam clamp 6 and the side clamp 5, and the framework is fixed through the mounting hole 19.

[0060] The lifting device 11 adjusts the clamping height, and the shroud material is stacked layer by layer and bonded / riveted.

[0061] Step 5: Dynamic tension monitoring

[0062] The central controller 12 controls the device two 8 and the device three 9 to drive the clamping mechanism to stretch and check the organ shroud, and the clamping mechanism adjusts the working parameters of the device two 8 and the device three 9 through the feedback of the infrared emitter 15 and the infrared receiver 16 in the moving process, so as to ensure that the middle beam clamp 6 and the side clamp 5 are horizontal.

[0063] Step 6: Shutdown inspection

[0064] After completing the assembly task, the power is turned off, and necessary inspection and maintenance are performed.

[0065] The working area is cleaned, and the next round of work is prepared.
