[0022] In order to make the purpose, technical solutions and advantages of the present application more clear, the technical solutions in the present application will be described clearly and completely below in combination with the drawings in the present application. Obviously, the described embodiments are some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the present application.

[0023] Various boards are the key core components of instrument control or electrical system (device), and their running characteristics and health conditions need to be verified through inspection and detection. The automation level of the board test fixture is an important basis for efficient test. The current related test fixtures are mostly manually operated, which brings errors and interference problems, and the sample measurement lacks a consistent test platform basis. Therefore, it is urgent to develop various board test tasks with automatic clamp platform.

[0024] The present application realizes data storage and other functions by forming an automatic clamp through a linear motor, a movable fastening seat, a torque sensor, a controller, a memory, a power supply and the like, and establishing a board test system and method.

[0025] Figure 1 It is the structural schematic diagram of the automatic clamp platform provided by the present application, as shown in Figure 1 The automatic clamp platform includes a first linear motor, a second linear motor, a first clamping strip, a second clamping strip, a controller and a rack, the first clamping strip is connected with the mover of the first linear motor, and the second clamping strip is connected with the mover of the second linear motor. The stators of the first linear motor and the second linear motor are respectively arranged on two sides of the rack, and the movers of the first linear motor and the second linear motor move under the action of the controller to drive the first clamping strip and the second clamping strip to move the to-be-tested board fixed on the rack.

[0026] Specifically, the stators of the first linear motor and the second linear motor are respectively arranged on two sides of the rack. The stator is usually the stationary part of the linear motor and is fixed on the rack. The mover of the first linear motor is connected to the first clamping strip, and the mover of the second linear motor is connected to the second clamping strip. The mover is the moving part of the linear motor, which moves under the control of the controller.

[0027] The first clamping strip is connected to the mover of the first linear motor and is driven by the movement of the first linear motor. The second clamping strip is connected to the mover of the second linear motor and is driven by the movement of the second linear motor.

[0028] In the linear motor, the stator is the fixed part, usually mounted on a bracket or rack. It contains a part of electromagnetic coils or magnets to generate a magnetic field. The role of the stator is to provide a stable magnetic field so that the mover can move in it to complete the work.

[0029] The mover of the linear motor is the part that can move linearly inside the stator. It usually realizes linear motion inside the stator through current excitation or magnetic field interaction. The mover usually has conductors or magnetic materials to respond to the current or magnetic field on the stator, thereby generating linear motion.

[0030] The movers of the first linear motor and the second linear motor are used to drive the corresponding clamping strips to move and fix the to-be-tested board. The stators are fixed on both sides of the rack to provide a stable magnetic field or current for the mover to move.

[0031] The controller controls the movement of the first linear motor and the second linear motor, as well as the movers connected to them, thereby controlling the movement of the first clamping strip and the second clamping strip. The rack is fixed on the ground or other support structure to support the entire automatic clamp platform and its operation.

[0032] Overall, the embodiment of the present application takes the controller as the core, realizes the automatic movement and fixation of the to-be-tested board through the combination of two linear motors and clamping strips, realizes the automatic clamp platform commonly used in automated testing and production, and can improve efficiency and accuracy.

[0033] Based on the above embodiment, the automatic clamp platform further comprises a fastening seat and a motor, and the fastening seat moves the to-be-tested board to both ends under the action of the controller through the motor.

[0034] Specifically, the fastening seat is a component installed on the automatic clamp platform, used to clamp and fix the board card to be tested. Under the action of the controller, the fastening seat can be adjusted and moved by the motor to ensure the accurate position and fixed state of the board card during testing or production. Among them, the motor can be a screw control motor, and the fastening seat can be a coaxial bidirectional T-shaped fastening seat.

[0035] Optionally, under the action of the controller, the coaxial bidirectional T-shaped fastening seat drives the two-end T-shaped fastening seat to move the other two ends of the board card to be tested through the screw control motor.

[0036] Among them, the controller is the core component of the entire automatic clamp platform, responsible for managing and coordinating the movement of each motor. It receives instructions from users or upper systems, as well as feedback information from sensors, and then controls the motor to achieve precise board card position adjustment and clamping force control.

[0037] The controller may also have a programming function for executing pre-set movement patterns or automated test sequences, thereby improving production efficiency and accuracy.

[0038] Based on any of the above embodiments, the automatic clamp platform further comprises: a first torque sensor, a second torque sensor and a third torque sensor, the first torque sensor is arranged on the first clamping strip, the second torque sensor is arranged on the second clamping strip, and the third torque sensor is arranged on the fastening seat.

[0039] Specifically, the first torque sensor is installed on the first clamping strip, which monitors and measures the torque or force exerted by the first clamping strip. The first torque sensor is used to detect the force exerted by the first clamping strip during adjustment or movement to ensure that it operates within a safe and expected range.

[0040] The second torque sensor is installed on the second clamping strip, which mainly measures the torque or force exerted by the second clamping strip. Similar to the first torque sensor, the second torque sensor helps monitor the operating force of the second clamping strip to ensure stability and accuracy when clamping the board card.

[0041] The third torque sensor is arranged on the fastening seat, which measures the torque or force exerted by the fastening seat. The third torque sensor can detect the clamping force exerted by the fastening seat on the board card to ensure that the clamping force is within the set range to prevent the board card from moving or being damaged.

[0042] The automatic clamp platform integrates the first torque sensor, the second torque sensor and the third torque sensor, so that the automatic clamp platform can monitor and adjust the operation of the clamping strip and the fastening seat in real time to ensure the safe clamping and correct positioning of the board card.

[0043] Based on any of the above embodiments, the automatic clamp platform further comprises a memory, the memory is connected with the first torque sensor, the second torque sensor and the third torque sensor respectively, and the measurement values of the first torque sensor, the second torque sensor and the third torque sensor are transmitted to the memory for storage.

[0044] Specifically, the memory can continuously record the torque or torque values (i.e. measurement values) measured by the first torque sensor, the second torque sensor and the third torque sensor, which can be used to analyze the performance and stability of the automatic clamp platform during production, helping to identify potential problems or optimize production processes.

[0045] By analyzing the measurement values in the memory, operators or engineers can evaluate the accuracy and reliability of the automatic clamp platform, ensuring the consistency and quality level of products during production. The measurement values in the memory also help in fault diagnosis and maintenance. If there is a problem or anomaly, the stored measurement values can be used to analyze and troubleshoot the root cause, thereby speeding up the repair process and reducing production downtime.

[0046] Based on any of the above embodiments, the memory is also connected with a controller, the controller is used to determine the fastening degree of the board card to be tested based on the measurement values stored in the memory, and control the first linear motor and the second linear motor based on the fastening degree.

[0047] Specifically, the measurement values of the first torque sensor, the second torque sensor and the third torque sensor stored in the memory are processed and analyzed by the controller, which can determine the fastening degree of the board card to be tested. Optionally, the controller can set a torque reference value according to the board card test requirements, and adaptively determine the fastening degree of the board card to be tested according to the measurement values uploaded by the memory.

[0048] The controller controls the first linear motor and the second linear motor based on the fastening degree. For example, if insufficient or excessive fastening is detected, the controller can automatically adjust the operation of the motor to achieve the set fastening standard.

[0049] As can be seen, the integration between the memory and the controller enhances the intelligence and controllability of the automatic clamp platform, improving the production efficiency and the stability of product quality.

[0050] Figure 2 is a control strategy diagram of the controller provided by the present application, as Figure 2As shown, the controller reads the torque measurement value from the memory and starts the first linear motor, the second linear motor, and the screw control motor. The controller controls the movement of the first and second linear motors based on the torque measurement value and acquires the torque measurement values ​​from the first and second torque sensors in real time. If the acquired torque measurement value reaches the torque reference value, it indicates that the first and second torque sensors are in position. At this time, the controller controls the movement of the screw control motor based on the torque measurement value from the third torque sensor and inputs the current torque measurement values ​​of the first and second torque sensors into the memory. If the torque measurement value of the third torque sensor reaches the torque reference value, it indicates that the third torque sensor is in position, and its current torque measurement value can be input into the memory.

[0051] Based on any of the above embodiments, the memory is used to query and determine the historical measurement values ​​of the historical sample when the board to be tested is a historical sample, and send the historical measurement values ​​to the controller so that the controller controls the first linear motor and the second linear motor based on the historical measurement values.

[0052] Specifically, the memory stores historical measurements of previous samples, which may include tightening torque, location, or other key parameters. Optionally, each historical sample may have its own unique identifier or index for easy retrieval later.

[0053] When a test board is clamped onto the automated fixture platform, it can be identified whether the test board is a known historical sample, such as through the label or barcode on the test board or through the identification program in the system.

[0054] If the board under test is identified as a historical sample, the memory will look up the corresponding historical measurement value based on its identifier or index and transmit the retrieved historical measurement value to the controller. The controller will then adjust its operation based on the received historical measurement value to control the first and second linear motors, ensuring that the processing of the board under test is consistent with that of historical samples.

[0055] Therefore, the embodiments of the present invention can utilize prior experience and data to achieve highly personalized processing and control of the boards to be tested, thereby ensuring the consistency and quality level of the production process.

[0056] Based on any of the above embodiments, the fastening bracket is a coaxial bidirectional fastening bracket.

[0057] Specifically, a coaxial two-way fastener is a specific type of fastening device, typically used to ensure that two objects can be precisely aligned and securely fixed on the same axis. During assembly and fastening, a coaxial two-way fastener can apply force or torque in two directions simultaneously to ensure the safety and accuracy of the fastener.
