In addition, handles 13 are provided on the left and right sides of the mounting frame of this embodiment to facilitate user operation.

[0053] The functions and workflow of the flexible joint parts clamping workstation of the present invention are as follows:

[0054] Transporting a parts and material box 35 and a tooling pallet 34: The user operates the loading and unloading HMI on the loading and unloading conveyor line 32, which is the display terminal of the industrial control integrated computer 27 (hereinafter referred to as the loading and unloading HMI), and clicks "Start Task." The control system dispatches the parts and material box 35 from the conveyor line entrance 29, through the intermediate conveyor line 28, and onto one of the loading and unloading conveyor lines 32. The user then clicks the "Send Tooling and Pallet" button on the loading and unloading HMI, dispatching the tooling pallet 34 and the clamping plate 4 from the conveyor line entrance 29, through the intermediate conveyor line 28, and onto another loading port on one of the loading and unloading conveyor lines 32. When the through-beam sensor 38 detects an object arrival signal, it stops the conveyor line, causing the parts and material box 35 or tooling pallet 34 to stop at the corresponding conveyor line stop. A drop-off block 39 is also provided to prevent material from being transported off the conveyor line due to a malfunction of the through-beam sensor 38.

[0055] Installing the tooling: The user uses the power-assisting arm 33 (in this embodiment, the power-assisting arm 33 adopts a manual pneumatic power-assisting arm 33) to clamp the power-assisting arm 33 slot 25 on the clamping sub-board 4 (same as the sub-board tooling), separate the sub-board tooling from the tooling tray 34, and step on the foot switch to release the tongue of the clamping motherboard 3, place the clamping sub-board 4 on the clamping motherboard 3, release the foot switch, and release the manual pneumatic power-assisting arm 33 to complete the operation of installing the tooling.

[0056] Installing parts: The user takes out the parts from the parts material box 35 and places them on the clamping plate 4, with the left end and the upper end close to the longitudinal positioning block 19 and the transverse positioning block 18 of the positioning reference, and then uses screws to set several pressing plates 5 on the clamping plate 4, aligning the pointed ends on the clamping plate 4 with the grooves on both sides of the parts, and using screws to pass through the pressing plates 5 and the mounting holes 6 respectively, and tighten the screws to complete the clamping and fixing function of the parts on the sub-plate.

[0057] Binding parts and tooling: Use the barcode scanner 36 to scan the QR code on the part, and the scanning result will be uploaded to the loading and unloading HMI; then click the read RFID button on the loading and unloading HMI, and the system scans the RFID patch 20 on the clamping plate 4 through the RFID reader 21 to complete the RFID reading. Click the bind button on the loading and unloading HMI to complete the binding of the parts and tooling, and upload the information to the management and control system for record.

[0058] Straightening and correction: After the tooling and parts are installed, align the dial indicator pointer with the longitudinal surface of the part, push the handle 13 connected to the longitudinal fixed slider 12, so that the dial indicator and the longitudinal fixed slider 12 move longitudinally on the longitudinal calibration track 10, and observe the rotation amplitude of the dial indicator pointer to see if it meets the clamping error threshold requirement. If not, remove the pressure plate 5 and reposition and clamp the part until it meets the standard. If it meets the requirements, operate the handle 13 on the transverse fixed slider 11 in the same way to complete the transverse clamping inspection.

[0059] Disassembly of tooling: Use the manual pneumatic booster arm 33 to align with the booster arm 33 slot 25, clamp the booster arm 33, step on the foot switch, release the latch, separate the clamping plate 4 and the clamping motherboard 3, then release the foot switch, then place the clamping plate 4 on the tooling tray 34, release the manual pneumatic booster arm 33, and return it to its original position.

[0060] Return the parts material box 35 and the tooling pallet 34: Manually click the button to return the tooling pallet 34 on the loading and unloading HMI, and the management and control system dispatches the conveyor line to transport the tooling pallet 34 from the loading and unloading transport line 32 through the intermediate conveyor line 28 to the conveyor line exit 30; then click the button to return the parts material box 35, and the management and control system dispatches the conveyor line to transport the parts material box 35 from the loading and unloading transport line 32 through the intermediate conveyor line 28 to the conveyor line exit 30.

[0061] Send out quality inspection material boxes: The user operates the quality inspection HMI on the quality inspection workbench 31, that is, the display terminal of the industrial control all-in-one computer 27 (hereinafter referred to as quality inspection HMI), clicks to start the task, and the management and control system dispatches the part material box 35 from the conveyor line entrance 29, through the intermediate conveyor line 28, to the quality inspection conveyor line.

[0062] Quality inspection work: Manually take the parts out of the parts material box 35, place them on the quality inspection workbench 31, take out the quality inspection tools, operate the quality inspection HMI, complete the quality inspection and random inspection of the parts, and after the quality inspection is completed, return the parts to the parts material box 35.

[0063] Return the quality inspection material box: The user operates the quality inspection HMI and clicks the "Return quality inspection material box" button. The management and control system dispatches the part material box 35 from the quality inspection conveyor line, through the intermediate conveyor line 28, to the conveyor line entrance 29, completing the quality inspection return task.

[0064] Process card handling: Since each batch of parts has a uniform identification mark and records its detailed parameter information, referred to as a process card, at the beginning of a batch task, the process card should be taken out from the parts material box 35 and placed in the process file cabinet 37. After a batch is fully processed, the process card should be taken out from the process file cabinet 37 and placed in the parts material box 35.
