[0016] An advantage of the present application is embodied in the following aspects:

[0017] Improve the assembly precision and quality: the workpiece clamping assembly is designed ingeniously, through the cooperation of the clamping base frame, the workpiece guide sliding rail, the workpiece sliding block and the clamping device, the workpiece can be accurately positioned and stably clamped. The workpiece turnover motor and turnover connecting rib equipped on the workpiece clamping support can realize multi-angle turnover of the workpiece, facilitate processing operation of different surfaces, effectively improve the assembly precision and ensure stable product quality.

[0018] Enhance assembly flexibility: the machining moving slide of the workpiece machining assembly is vertically arranged with the machining lifting slide, and the machining slide block and the lifting slide block can be moved flexibly, so that the machining tool can be freely adjusted in the three-dimensional space, and the assembly requirements of workpieces with different shapes and sizes are adapted, and the assembly flexibility of the system is greatly enhanced.

[0020] Comprehensively detect the quality of the workpiece: in the workpiece testing module, the visual detection head can slide on the testing piece sliding groove to comprehensively detect the appearance of the workpiece; the vibration generator can simulate the actual working environment to detect the performance of the workpiece under vibration conditions, and the quality of the workpiece is comprehensively evaluated through various detection methods to timely find potential problems.

[0021] Improve test efficiency: the workpiece test limiting block can be flexibly adjusted in position to quickly adapt to the test requirements of workpieces of different specifications, and the test driving cylinder can automatically control the movement of the limiting block to reduce manual operation and improve test efficiency.

[0022] The application also provides a method for testing the vibration stability of an intelligent terminal assembly based on visual detection, and the process comprises the following steps:

[0023] Step one: open the clamping limiting shaft, place the terminal shell to be assembled on the clamping workbench, at this time the clamping workbench is horizontally placed, the workpiece guiding slide on the clamping base frame guides the workpiece sliding block to move to the appropriate position, the clamping base of the clamping device is linked with the workpiece sliding block to drive the workpiece clamping support to move, so that the terminal shell is in the initial position convenient for machining, and the limiting cylinder drives the clamping limiting block to cooperate with the clamping limiting groove to accurately limit the clamping workbench;

[0024] Step two: the workpiece turnover motor on one side of the workpiece clamping support is in standby state for subsequent turnover requirements, and the workpiece test limiting blocks on both sides of the workpiece test platform are prepared, one side is fixed, and the other side can move along the workpiece test sliding groove under the action of the test driving cylinder to prepare for subsequent test positioning;

[0025] Step three: after the limiting is completed, the workpiece turnover motor is started, the clamping workbench is driven to rotate around the clamping rotation shaft through the turnover connecting rib at the output end, the workpiece is turned over, and at this time the clamping workbench is vertically arranged with the ground;

[0026] Step 4: The workpiece processing assembly is started. The processing moving slide rail between the processing support columns drives the processing sliding block to move laterally. The processing lifting slide rail on the processing sliding block causes the lifting sliding block to move longitudinally, thereby driving the lifting mounting plate to the designated processing position.

[0027] Step 5: The locking structure on the lifting mounting plate begins to work. The fine-tuning drive motor drives the fine-tuning sliding block to fine-tune the position on the fine-tuning slide rail to ensure accuracy. The locking drive motor drives the locking head to rotate, which cooperates with the locking block on the fixing rib. Guided by the locking hole and locking bushing, one side of the terminal shell is firmly locked to the screw, completing the initial assembly. At this time, the clamping work platform is set perpendicular to the ground.

[0028] Step 6: The workpiece flipping motor starts, and the flipping connecting rib at the output end drives the clamping work platform to rotate around the clamping rotation axis, thereby flipping the workpiece.

[0029] Step 7: After flipping, the limit drive motor drives the clamping limit shaft to rotate, and at the same time the limit cylinder pushes the clamping limit block to cooperate with the clamping limit groove to accurately limit the clamping work platform, ensuring that the terminal shell is in the correct position after flipping, which is convenient for subsequent secondary assembly work. At this time, the clamping work platform is set perpendicular to the ground.

[0030] Step 8: The locking structure on the lifting mounting plate begins to work. The locking drive motor drives the locking head to rotate, cooperating with the locking block on the fixing rib. Guided by the locking hole and locking bushing, the other side of the terminal housing is firmly locked to the screw, completing the initial assembly and splicing of the two sides of the terminal housing.

[0031] Step 9: The workpiece flipping motor starts, and the flipping connecting rib at the output end drives the clamping work platform to rotate around the clamping rotation axis, so that the clamping work platform is placed horizontally. The limit drive motor drives the clamping limit axis to rotate, releasing the limit on the terminal shell.

[0032] Step 10: The assembled terminal shell is transferred to the workpiece testing platform by a transfer suction cup. The test drive cylinder pushes the movable workpiece test limit block, which works together with the fixed workpiece test limit block to accurately position the terminal shell in the test position.

[0033] Step 11: The workpiece testing module starts running. The test piece slide on the top of the test support frame guides the vision inspection head to move and inspect the terminal shell. At the same time, the vibration generator at the bottom of the workpiece testing platform is activated, causing the terminal shell to vibrate. The vision inspection head observes whether the terminal shell is loose.

[0034] Another beneficial effect of the present invention is specifically reflected in the following aspects:

[0035] High assembly precision: During assembly, a fine-tuning drive motor drives a fine-tuning slider to adjust its position on the fine-tuning rail, ensuring high precision. The locking structure utilizes a locking drive motor to rotate the locking head, which cooperates with the locking block on the fixing rib. Guided by the locking holes and locking bushings, the terminal housing is securely locked, effectively guaranteeing assembly quality and reducing the defect rate caused by inaccurate assembly.

[0036] High operational flexibility: The workpiece flipping motor drives the clamping work platform to rotate around the clamping rotation axis, enabling flexible workpiece flipping. This design eliminates the need for manual workpiece flipping during assembly, reducing labor intensity and improving operational efficiency, allowing for rapid completion of assembly work on different sides of the terminal housing.

[0037] Precise and reliable positioning: After flipping, the limit drive motor drives the clamping limit shaft to rotate, while the limit cylinder pushes the clamping limit block to engage with the clamping limit groove, precisely limiting the clamping work platform. This dual-limiting method ensures the accurate position of the terminal shell after flipping, providing a stable and reliable foundation for subsequent secondary assembly work and further improving assembly accuracy.

[0038] Comprehensive and effective testing: In the testing phase, on the one hand, the visual inspection head is guided to move through the test piece slide to conduct a comprehensive inspection of appearance-related items such as the appearance and size of the terminal shell; on the other hand, the vibration generator at the bottom of the workpiece testing platform is activated to simulate the actual working environment and test the performance and stability of the terminal shell under vibration conditions.

[0039] High degree of automation: Throughout the entire process, from workpiece clamping, flipping, assembly to testing, a large amount of work is completed by automated equipment, reducing manual operation, lowering labor costs, and avoiding the instability caused by manual operation, thus improving the stability and consistency of the production process.

[0040] In operation, the terminal shell to be assembled is placed on the workpiece processing platform, at which point the station clamping assembly begins to work. The workpiece guide rail on the clamping base frame functions, guiding the workpiece sliding block to a suitable position. The clamping base of the clamping device is linked with the workpiece sliding block, driving the workpiece clamping bracket to move, so that the terminal shell is in an initial position that is convenient for processing.

[0041] The limit cylinder pushes the clamping limit block to cooperate with the clamping limit groove, so as to accurately limit the clamping work platform, making the clamping work platform horizontal and in a limited state.

[0042] The workpiece turnover motor on one side of the workpiece clamping support is in standby state, ready for subsequent turnover requirements; the workpiece test limiting blocks on both sides of the workpiece test platform are also prepared, one side is fixed, and the other side can move along the workpiece test sliding groove under the action of the test driving cylinder, preparing for subsequent test positioning.

[0043] The workpiece processing assembly is started, the processing moving sliding rails between the processing support columns drive the processing sliding blocks to move transversely, the processing lifting sliding rails on the processing sliding blocks make the lifting sliding blocks move longitudinally, and then drive the lifting mounting plate to reach the specified processing position, making space positioning for subsequent assembly operation.

[0044] After the limiting is completed, the workpiece turnover motor is started, the turnover connecting rib at the output end drives the clamping work platform to rotate around the clamping rotation shaft, realizing workpiece turnover, at this time the clamping work platform is vertically arranged with the ground.

[0045] The locking structure on the lifting mounting plate starts to work, the fine adjustment driving motor drives the fine adjustment sliding block to fine adjust the position on the fine adjustment sliding rail, ensuring accuracy. The locking driving motor drives the locking head to rotate, cooperates with the locking block on the fixing rib, and is guided through the locking hole and the locking shaft sleeve to firmly lock one side of the terminal shell with the screw, completing preliminary assembly splicing.

[0046] The workpiece turnover motor is started, the turnover connecting rib at the output end drives the clamping work platform to rotate around the clamping rotation shaft, realizing workpiece turnover. After turnover, the limiting driving motor drives the clamping limiting shaft to rotate, and at the same time the limiting cylinder pushes the clamping limiting block to cooperate with the clamping limiting groove, accurately limiting the clamping work platform, ensuring the position of the terminal shell after turnover is accurate, facilitating subsequent secondary assembly work.

[0047] The locking structure on the lifting mounting plate works again, the locking driving motor drives the locking head to rotate, cooperates with the locking block on the fixing rib, and is guided through the locking hole and the locking shaft sleeve to firmly lock the other side of the terminal shell with the screw, completing assembly splicing of both sides of the terminal shell.

[0048] The workpiece turnover motor is started, the turnover connecting rib at the output end drives the clamping work platform to rotate around the clamping rotation shaft, so that the clamping work platform is horizontally placed, the limiting driving motor drives the clamping limiting shaft to rotate, and the limiting of the terminal shell is released.

[0049] The assembled terminal shell is transferred to the workpiece test platform through the transfer suction cup, the movable workpiece test limiting block is pushed by the test driving cylinder, and cooperates with the fixed workpiece test limiting block to accurately position the terminal shell at the test position.

[0050] The workpiece testing module starts to operate, the testing piece sliding groove on the top of the testing support frame guides the visual detection head to move, appearance related items such as appearance and size of the terminal shell are detected; meanwhile, the vibration generator on the bottom of the workpiece testing platform starts to operate, so that the terminal shell vibrates, and the visual detection head observes whether the terminal shell is loose.
