Description

Technical Field

[0001] This utility model belongs to the technical field of terminal crimping machines, and relates to a semi-automatic terminal crimping machine and its safety protection structure. Background Technology

[0002] Existing terminal crimping machines suffer from issues such as pressure fluctuations, positioning deviations, and missed defects in terminal mating stability. This poor stability stems from a combination of factors: reduced equipment rigidity and unstable base leading to deformation; worn or insufficiently adjusted molds causing significant variations in pressure waveforms; wire misalignment and abnormal tape cutting directly impact mating accuracy; and electromagnetic interference from the factory and unstable power supply voltage can interfere with pressure sensor signals. Safety deficiencies include easily damaged or unreset protective covers, malfunctioning photoelectric protection and two-hand operating devices, easy hand contact with the punch during manual feeding in semi-automatic equipment, and the risk of electric shock from poor grounding and damaged power cords. Therefore, there is an urgent need for a semi-automatic terminal crimping machine and a corresponding safety protection structure to address these problems. Utility Model Content

The lower end of the clamping component is provided with a set of front movable frames for batch conveying of pre-insulated terminals. Several sets of inner placement cavities for loading pre-insulated terminals are evenly distributed in the front movable frames.

[0007] In a preferred embodiment, the interval between every two sets of inner placement cavities is the same as the distance between every two sets of clamping heads. The lower end of the front movable frame is provided with a set of lower guide rails for precise positional guidance and movement. The upper left side of the front movable frame is provided with a set of movable seats for providing movement power.

[0008] In a preferred embodiment, the movable seat has a built-in motor and moving wheels. A set of guide rails for supporting and guiding the movable seat is located on its rear side.

During operation, the main control terminal is first activated, and the movable seat motor drives the front movable frame to move along the lower guide rail to the working position, ensuring precise alignment between the pre-insulated terminals and the clamping heads. The main adjusting cylinder synchronously descends, driving the connecting plate downwards, while the auxiliary adjusting cylinder finely adjusts the height of each clamping head to complete terminal clamping. After the guide components feed the stripped wire into the clamping head crimping area, the main adjusting cylinder applies secondary pressure to achieve crimping and forming of the terminals and wire. After crimping is completed, the movable seat resets, and the front movable frame returns to its initial position to remove the finished product.

The front left and right sides of the mounting bracket each have a set of front guide rails for adjusting the height of the front protective plate. A front protective plate for safety protection of the clamping components is located in front of both sets of front guide rails. After starting the equipment, the main control terminal first activates the guide component transmission system. The motor drives the gear set to rotate the movable adjusting roller, ensuring even wire feeding. The wire quickly passes through the inner hole of the limit conductor seat, and the electric telescopic rod extends synchronously to the preset angle. The conductor frame adjusts its tilt accordingly to ensure that the wire enters the outlet in a straight path. When the wire reaches the clamping component area, the main adjusting cylinder starts the downward program, and the connecting plate drives the auxiliary adjusting cylinder and clamping head to descend, accurately pressing the pre-insulated terminal and the wire. During the pressing process, the front movable frame makes a slight adjustment along the lower guide rail to ensure that the terminal and the wire axis are completely aligned. After pressing is completed, the movable seat resets the guide component, the electric telescopic rod retracts and returns to its original position, and the front protective plate remains closed throughout the process.

During operation, the main control terminal is started first, and the front movable frame is driven by the movable seat motor to move along the lower guide rail to the working position, so that the pre-insulated terminals and the clamping heads are precisely aligned. The main adjusting cylinder moves down synchronously, driving the connecting plate to descend, and the auxiliary adjusting cylinder finely adjusts the height of each clamping head to complete the terminal clamping. After the guide component feeds the stripped wire into the clamping head crimping area, the main adjusting cylinder applies pressure a second time to achieve the crimping and forming of the terminal and the wire. After the crimping is completed, the movable seat resets, and the front movable frame returns to the initial position to remove the finished product. After the equipment is started, the main control terminal first activates the transmission system of the guide component. The motor drives the gear set to rotate the movable adjusting roller, so that the wire passes through the wire hole in the limit wire seat at a uniform speed. The electric telescopic rod extends synchronously to the preset angle, and the wire frame adjusts its tilt accordingly to ensure that the wire enters the outlet in a straight path. When the wire reaches the clamping component area, the main adjusting cylinder starts the downward program. The connecting plate drives the auxiliary adjusting cylinder and the clamping head to descend, accurately pressing the pre-insulated terminal and the wire. During the pressing process, the front movable frame makes a slight adjustment along the lower guide rail to ensure that the terminal and the wire axis are completely aligned.
