Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] I. Overall Structural Composition like Figure 1-3 As shown, the assembly fixture mainly includes the following core components: Basic support structure: Robotic arm 1: As the movement and execution mechanism of the entire gripper, it provides spatial positioning function; Fixed mounting plate 2: Fixed to the bottom of the robotic arm, serving as the mounting base for other components; Movable plate 3: There are two of them, located below the fixed mounting plate, and their positions can be adjusted; Adjustment plate 4: Two are set under each movable plate, which can be used for angle adjustment.

[0022] Clamping execution structure: Clamping plate 5: A clamping component that directly contacts the connector housing; Anti-slip pad 6: Fixed to the inside of the clamping plate, made of high friction coefficient materials such as rubber or polyurethane, to prevent the workpiece from slipping during clamping; Pressure sensor 7: Embedded in the middle of the inner side of the adjustment plate, it monitors the clamping force in real time.

[0023] Connection and transmission structure: Connecting frame 8 and connecting ear 9: connect the clamping plate and the adjusting plate to form a stable force transmission path; Movable slot 10: Provides space for the connecting ear to move, ensuring that the clamping plate can move flexibly.

[0024] II. Working Mode of Each Component 1. Implementation of the position adjustment component ( Figure 3 , Figure 7 ) Components: 23. T-shaped slide rail 24. T-shaped slider 25. Two-way lead screw 26. Motor 27.

[0025] Work process: When it is necessary to adjust the spacing between the two movable plates 3 to accommodate connector housings of different sizes, the controller issues a command to start the motor 26. The motor drives the bidirectional lead screw 25 to rotate. Since the two ends of the bidirectional lead screw have opposite thread directions, the two T-shaped sliders 24 move synchronously towards or away from each other within the T-shaped groove 23, thereby driving the movable plates 3 to precisely adjust the position spacing.

[0026] 2. Implementation of the angle adjustment component ( Figure 7-9 ) Components: Shaft 11, gear 13, adjusting block 14, rack 15, threaded rod 17, rotating block 19.

[0027] Work process: The operator rotates the rotating block 19, causing the threaded rod 17 to rotate. The threaded rod engages with the threaded groove 18 on the adjusting block 14, driving the adjusting block to move horizontally within the adjusting port 12. The racks 15 at the front and rear ends of the adjusting block drive two gears 13 to rotate synchronously. The gears drive the adjusting plate 4 to rotate around the axis of the rotating shaft 11, thereby achieving precise adjustment of the clamping angle.

[0028] Locking mechanism: After adjusting to the appropriate angle, tighten the locking bolt 20 so that its end is in close contact with the outer side of the vertical part of the L-shaped fixing plate 16, generating sufficient friction to lock the rotating block 19 and prevent the angle from changing.

[0029] Guide structure: The guide bar 21 at the top of the adjusting block 14 cooperates with the guide groove 22 inside the adjusting port 12 to ensure that the adjusting block moves smoothly and does not deflect.

[0030] 3. Implementation of clamping force monitoring and control ( Figure 4-6 ) Force transmission path: Clamping plate 5 → Connecting frame 8 → Pressure sensor 7 measuring end Work process: When the clamping plate 5 contacts the connector housing via the anti-slip pad 6 and applies clamping force, the force is transmitted to the measuring end of the pressure sensor 7 through the connecting frame 8. The pressure sensor converts the force signal into an electrical signal in real time and transmits it to the controller.

[0031] Control system: The controller receives the pressure sensor signal and compares it with the preset clamping force threshold. When the clamping force is detected to reach the set value, the controller stops the motor 26 to ensure that the clamping force is precisely controlled within a safe range, thus ensuring secure clamping while preventing overload damage to the workpiece.

[0032] III. Operating Procedures 1. Preparation: Adjust the spacing between the movable plates and the angle of the adjustment plates in advance according to the size and shape of the connector housing to be assembled; 2. Positioning and clamping: The robotic arm moves the clamp to the working position, aligning the clamping plate with the connector housing; 3. Automatic clamping: When the clamping program is started, the motor drives the movable plate to move, and the clamping plate contacts the workpiece and applies clamping force; 4. Force monitoring: The pressure sensor provides real-time feedback on the clamping force, and the clamping force automatically stops when the set value is reached; 5. Assembly Operation: The robotic arm carries the fixture to complete the assembly of the connector housing; 6. Release the workpiece: Reverse drive motor to release the clamping plate and complete the entire work cycle.

[0033] This invention effectively solves the technical problems of inaccurate clamping force control and poor adaptability during connector housing assembly through innovative force monitoring and multiple adjustment mechanisms, and has high practical value and promising prospects for promotion.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
