Detailed Implementation

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] like Figure 1The sensor FPC assembly equipment shown includes a machine frame 100, a turntable mechanism is provided inside the machine frame 100, and multiple assembly fixtures 210 driven by the turntable mechanism are provided on the turntable mechanism. The machine frame 100 is also provided with a core feeding mechanism 300, a solder joint three-dimensional detection mechanism 400, a board assembly mechanism 500, an FPC fastening mechanism 600, an FPC hot riveting mechanism 700, and a semi-finished product unloading mechanism 800, which sequentially perform core feeding, solder joint detection, board assembly, FPC fastening, FPC positioning hot riveting, and semi-finished product unloading. In practical implementation, once the FPC flexible circuit board is mounted on the sensor core, batches of cores are stored in the corresponding structure of the core loading mechanism 300, and batches of board holders are stored in the corresponding structure of the board holder assembly mechanism 500. For assembly, firstly, the core loading mechanism 300 loads the stored cores into the corresponding assembly fixture 210 on the turntable mechanism. Next, the turntable mechanism transfers the assembly fixture 210 carrying the loaded cores to the corresponding position of the solder joint three-dimensional inspection mechanism 400. The solder joint three-dimensional inspection mechanism 400 checks whether the solder joints of the FPC flexible circuit board on the core meet the requirements. If they do, the next process proceeds normally; otherwise, they are rejected in subsequent processes. Next, the turntable mechanism transfers the assembly fixture 210 carrying the inspected cores to the corresponding position of the board holder assembly mechanism 500. The board holder assembly mechanism 500 assembles the board holders into the board holders that have passed the solder joint three-dimensional inspection mechanism in the previous step. The process begins with the core assembly, which has passed inspection (400). Next, the turntable mechanism transfers the assembly fixture 210, carrying the assembled core, to the corresponding position of the FPC fastening mechanism 600. The FPC fastening mechanism 600 then fastens the FPC flexible circuit board from the core onto the board base, and removes any defective products detected in the previous process. Next, the turntable mechanism transfers the assembly fixture 210, carrying the core with the fastened FPC flexible circuit board, to the corresponding position of the FPC hot riveting mechanism 700. The FPC hot riveting mechanism 700 hot-rivets the FPC flexible circuit board fastened to the board base. Next, the turntable mechanism transfers the assembly fixture 210, carrying the semi-finished product with the FPC flexible circuit board hot-riveted to the board base, to the corresponding position of the semi-finished product unloading mechanism 800. The semi-finished product unloading mechanism 800 inspects and unloads the semi-finished products from the assembly fixture 210, temporarily storing defective products and transferring good products to the next process. This sensor FPC assembly process is highly automated, fast, efficient, and produces stable assembly quality.

[0034] Based on the above, such as Figure 1As shown, the equipment frame 100 is provided with a mounting base plate 101. The turntable mechanism includes a rotating disk 201 rotatably mounted on the mounting base plate 101 and a fixed disk 202 fixedly mounted on the mounting base plate 101 and located above the rotating disk 201. The assembly fixture 210 has eight evenly arranged on the rotating disk 201 and rotates with the rotating disk 201. In this specific embodiment, the assembly fixture 210 is provided with two product assembly placement slots. Two FPC hot riveting mechanisms 700 are used to hot rivet the products in the two slots of the assembly fixture 210 respectively. When the rotary table 201 stops, the eight assembly fixtures 210 correspond to the core loading mechanism 300, the solder joint three-dimensional inspection mechanism 400, the board assembly mechanism 500, an inspection mechanism for inspecting the products in the assembly fixture 210 (the corresponding workstation of the assembly fixture 210 can also be used as a backup), the FPC fastening mechanism 600, the first FPC hot riveting mechanism 700, the second FPC hot riveting mechanism 700, and the semi-finished product unloading mechanism 800. The structure is compact, and the provision of additional workstations facilitates subsequent maintenance and upgrades.

[0035] Based on the above, such as Figures 1 to 4 As shown, the core feeding mechanism 300 includes a core feeding mechanism 310, a core feeding detection mechanism 320 spanning the core feeding mechanism 310, and a core transfer and implantation mechanism for transferring the core between the assembly fixture 210 and the core feeding mechanism 310.

[0036] In this specific embodiment, the core feeding mechanism 310 includes two support plates 311 vertically arranged side by side on the mounting base plate 101, two first horizontal slide rail assemblies 312 horizontally arranged corresponding to each other inside the two support plates 311, a first slide plate 313 horizontally slidably arranged on the two first horizontal slide rail assemblies 312, a first horizontal drive mechanism 314 arranged outside the support plates 311 and connected to drive the first slide plate 313 to slide horizontally, two second horizontal slide rail assemblies 315 horizontally arranged corresponding to each other inside the two support plates 311 and located below the two first horizontal slide rail assemblies 312, a second slide plate 316 horizontally slidably arranged on the two second horizontal slide rail assemblies 315, a second horizontal drive mechanism 317 arranged inside the support plates 311 and connected to drive the second slide plate 316 to slide horizontally, and a plurality of core storage trays 318 for batch storage of cores. The first slide plate 313 and the second slide plate 316 are both provided with limiting mechanisms for limiting the core storage trays 318.

[0037] During feeding, the core storage tray 318 filled with cores is placed on the limiting mechanism on the first slide plate 313 and the second slide plate 316; the first slide plate 313, driven by the first horizontal drive mechanism 314, moves along the first horizontal slide rail assembly 312 to the picking range of the core transfer and implantation mechanism, and the second slide plate 316, driven by the second horizontal drive mechanism 317, moves along the second horizontal slide rail assembly 315 to the picking range of the core transfer and implantation mechanism; when the cores in the core storage tray 318 on the first slide plate 313 are taken out by the core transfer and implantation mechanism, the first slide plate 313, driven by the first horizontal drive mechanism 314, moves along the first horizontal slide rail assembly 312 to outside the picking range of the core transfer and implantation mechanism, removes the empty core storage tray 318, and replaces it with one loaded with cores. The core storage tray 318 is driven by the first horizontal drive mechanism 314 and moved along the first horizontal slide rail assembly 312 to the picking range of the core transfer and implantation mechanism. After the core storage tray 318 on the second slide rail 316 has been empty of cores, the second slide rail 316 is driven by the second horizontal drive mechanism 317 and moved along the second horizontal slide rail assembly 315 to the outside of the picking range of the core transfer and implantation mechanism to remove the empty core storage tray 318. The core storage tray 318 loaded with cores is then replaced. The second slide rail 316 is driven by the second horizontal drive mechanism 317 and moved along the second horizontal slide rail assembly 315 to the picking range of the core transfer and implantation mechanism. The double-layer reciprocating feeding design is simple in structure, convenient in feeding, and has few failures.

[0038] The core loading and inspection mechanism 320 includes a third horizontal drive mechanism 321 fixedly mounted on the mounting base plate 101, a fourth horizontal drive mechanism 322 mounted on the third horizontal drive mechanism 321 and driven by the third horizontal drive mechanism 321 to move along a first horizontal direction, a first vertical drive mechanism 323 vertically mounted on the fourth horizontal drive mechanism 322 and driven by the fourth horizontal drive mechanism 322 to move horizontally along a direction perpendicular to the first horizontal direction, and an inspection camera assembly 324 fixedly mounted on the first vertical drive mechanism 323 and driven by the first vertical drive mechanism 323 to move vertically. The inspection camera assembly 324 is an industrial camera assembly including a ring light source, which enables the inspection and positioning of each core before loading, avoids poorly loaded core assemblies, and determines the angle that the core transfer and implantation mechanism needs to accurately compensate for during the transfer process, reducing resource waste and improving assembly accuracy.

The first electric gripper 332 is provided with grippers that match the core clamping position. During the core transfer process, the rotating core can be rotated, and the core with angular displacement during storage can be corrected and compensated with high precision, thereby improving the assembly accuracy.

[0040] Based on the above, such as Figure 1 As shown, the 3D solder joint inspection mechanism 400 includes a solder joint inspection fixing base plate disposed above the transfer path of the assembly fixture 210. A solder joint inspection driving mechanism is disposed on the solder joint inspection fixing base plate, and a 3D inspection component driven by the welding joint inspection driving mechanism is disposed on the welding joint inspection driving mechanism. In a specific implementation, the 3D inspection component is a commercially available 3D industrial camera. The solder joint inspection fixing base plate is located above the stopping position of the corresponding workstation assembly fixture 210 and is fixed by multiple supports respectively located on the fixing plate 202. This allows for further inspection of the solder joints on the FPC flexible circuit board on the core to be loaded, reducing resource waste and improving the assembly yield.

[0041] Based on the above, such as Figure 1 and Figure 5 As shown, the plate assembly mechanism 500 includes a plate feeding mechanism 510, a plate transfer and mounting mechanism for transferring and placing the plate between the plate feeding mechanism 510 and the assembly fixture 210, and a plate detection mechanism 530 located within the plate transfer and mounting mechanism's plate transfer movement range. The plate transfer and mounting mechanism includes a second four-axis robot 521 fixedly mounted on the mounting base plate 101 and a vacuum adsorption head 522 driven by the second four-axis robot 521 to move horizontally, move vertically, and rotate horizontally. The vacuum adsorption head 522 is provided with an adsorption sleeve that matches the plate, and the vacuum adsorption head 522 is connected to a vacuum device.

[0042] In practical implementation, the plate holder inspection mechanism 530 is an industrial camera assembly including a ring light source. It can inspect each plate holder before loading, avoid loading defective plate holder assemblies, and determine the angle that the plate holder transfer and installation mechanism needs to accurately compensate during the transfer process, thereby reducing resource waste and improving assembly accuracy.

[0043] In this specific embodiment, the board base detection mechanism 530 is provided with an anti-static connector 540 to eliminate the adverse effects of static electricity on the high-precision FPC flexible circuit board on the board base detection mechanism 530.

[0044] Based on the above, such as Figure 1 and Figure 6As shown, the FPC fastening mechanism 600 includes a manual operation control console 610, a fastening detection mechanism 620 for detecting the completion of FPC fastening, a defective product placement mechanism 630 for placing defective products after fastening, and an ion fan for eliminating static electricity.

The operator first transfers the defective products in the assembly fixture 210 to the defective product temporary storage tray on the defective product placement mechanism 630 according to the indicator lights. Then, the FPC on the core of the assembly fixture 210 is fastened to the plate base. After the fastening is completed, the fastening detection mechanism 620 detects the fastened products in the assembly fixture 210. According to the indicator lights, the defective products that fail the detection are transferred to the defective product temporary storage tray on the defective product placement mechanism 630. Then, the fastened products are transferred to the next process with the rotating plate 201.

[0056] Based on the above, such as Figure 1 , Figure 10 and Figure 11 As shown, the semi-finished product unloading mechanism 800 includes a flipping mechanism 810, a semi-finished product detection mechanism 820, a defective product temporary storage mechanism 830, a semi-finished product transfer mechanism, and a semi-finished product unloading and conveying mechanism 850, all mounted on the mounting base plate 101.

[0057] In this specific embodiment, the flipping mechanism 810 includes a fifth horizontal drive mechanism 811 fixed on the mounting base plate 101, a second vertical drive mechanism 812 driven by the fifth horizontal drive mechanism 811 to move horizontally, and a rotating gripper 813 driven by the second vertical drive mechanism 812 to move vertically. The rotating gripper 813 is provided with claw fingers that match the gripping part of the semi-finished product. In this specific embodiment, the fifth horizontal drive mechanism 811 is a linear motor assembly, and the second vertical drive mechanism 812 is a cylinder assembly with controllable stroke.

[0058] The semi-finished product inspection mechanism 820 includes a semi-finished product inspection fixing bracket fixed on the mounting base plate 101 and an industrial camera assembly disposed on the semi-finished product inspection fixing bracket. The defective product temporary storage mechanism 830 includes a defective product temporary storage fixing bracket fixed on the mounting base plate 101, a temporary storage horizontal limiting plate fixed horizontally on the defective product temporary storage fixing bracket, and a replaceable defective product temporary storage tray disposed on the temporary storage horizontal limiting plate. The semi-finished product transfer mechanism includes a third- or fourth-axis robot 841 fixedly disposed on the mounting base plate 101 and a second electric gripper 842 driven by the third- or fourth-axis robot 841 to move horizontally, move vertically, and rotate horizontally. The second electric gripper 842 is provided with grippers that match the clamping position of the semi-finished product. The semi-finished product unloading and transmission mechanism 850 is an electrically driven transmission belt that drives the product temporary storage block to move linearly.

[0059] In practice, the flipping mechanism 810 flips the assembled semi-finished products, and the semi-finished product transfer mechanism transfers the flipped semi-finished products to the semi-finished product inspection mechanism 820 for inspection. After inspection, the semi-finished product transfer mechanism places defective products to the defective product temporary storage mechanism 830 and transfers good products to the semi-finished product unloading and conveying mechanism 850, which then transports the products to the next process. This automated unloading system is fast, efficient, and ensures stable quality.
