Specifically, each clamp arm 42 is provided with a limiting shaft 43 at the lower end, and the clamp arm mounting plate 32 is provided with mounting grooves 321 corresponding to each terminal positioning clamp 40, and the two opposite side walls of the mounting groove 321 are provided with limiting grooves 322 corresponding to the limiting shaft 43, and the limiting grooves 322 on the same mounting groove 321 are obliquely opposite, and the two clamp arms 42 of the terminal positioning clamp 40 are arranged in the corresponding limiting grooves 322, and the limiting shaft 43 is slidably connected with the corresponding limiting grooves 322.

[0043] In the present invention, the clamping seat 30 is provided with a return spring (not shown) which makes the clamping arm mounting plate 32 always have a tendency to move downward. The clamping drive mechanism includes a pre-opening cylinder 33 and a fully-opening cylinder 34 fixedly arranged on the clamping seat 30. The fully-opening cylinder 34 is provided with two, and the two fully-opening cylinders 34 are symmetrically arranged on both sides of the pre-opening cylinder 33. The output ends of the pre-opening cylinder 33 and the fully-opening cylinder 34 both extend upward, and the stroke of the output end of the pre-opening cylinder 33 is smaller than the stroke of the output end of the fully-opening cylinder 34. Figure 6As shown, in the clamping state, the clamp arm mounting plate 32 pulls the clamp block 41 downward under the action of the reset spring. At this time, the limit shaft 43 on the clamp arm 42 moves to the highest point of the limit groove 322, and the clamp block 41 is located at the clamp groove 44 above the clamp arm limit plate 31 and clamped on both sides of the terminal, so that the terminal is clamped and positioned through the clamp groove 44; when the output end of the pre-open cylinder 33 pushes the clamp arm mounting plate 32 upward to move, the clamp block 41 is in a semi-open state, at this time, the wire can enter the terminal positioning clamp 40, and the terminal on the wire is located between the two clamp blocks 41; when the output end of the fully-open cylinder 34 pushes the clamp arm mounting plate 32 upward to move, the clamp arm mounting plate 32 drives the clamp arm 42 to move to the highest point, at this time, the limit shaft 43 on the clamp arm 42 is located at the lowest point of the limit groove 322, and the clamp block 41 is fully opened, so that the terminal can be moved out from between the two clamp blocks 41 without any obstacles. It should be understood that the number and positions of the full-open cylinders and the pre-open cylinders can be set as needed, and the clamping drive mechanism can also be replaced by a servo motor or a drive module.

When loading, the turntable 110 moves the material frame 120 to the top of the loading mechanism of the present application, and then the turntable 110 moves downward to make the mold strip 130 on the material frame 120 fall into the positioning groove 51 of the mold strip 130, and at the same time, the wire clamp 140 on the material frame 120 is located between the clamp opening slide 62 and the clamping seat 30, then, the lifting cylinder controls the clamping seat 30 to move upward, so that the height of the terminal positioning clamp 40 is consistent with the height of the jack on the mold strip, and then the pre-opening cylinder 33 makes the terminal positioning clamp 40 in a semi-open state, and the push rod 64 of the wire clamp opening assembly is in the wire clamp The opening cylinder 63 is driven to be inserted between the two clamping plates of the wire clamp 140 to open the wire clamp 140. At this time, the terminal of the wire is manually loaded into the terminal positioning clamp 40, and the front end of the terminal is extended forward outside the terminal positioning clamp 40, and the tail of the wire is placed in the wire clamp 140. When the wire is clamped, the pre-opening cylinder 33 and the wire clamp opening cylinder 63 retract and reset, and the terminal positioning clamp 40 clamps and positions the terminal. Next, the pushing cylinder controls the feeding seat 20 to push toward the mold strip, and the terminal positioning clamp 40 on the feeding seat 20 inserts the terminal of the wire into the jack of the mold strip 130. After being pushed into place, the fully-opening cylinder 34 fully opens the terminal positioning clamp 40, and then the pushing cylinder retracts and resets, and the lifting cylinder retracts and resets. Finally, the turntable 110 moves upward to remove the wire from the feeding mechanism, and then the material frame 120 with the wire inserted is moved into the injection mold by rotating the turntable 110, thereby completing the positioning and feeding of the wire.

[0045] To sum up, the utility model provides a feeding seat that can be moved back and forth by a feeding drive mechanism, and terminal positioning clamps arranged in a straight line are provided on the clamping seat at the front end of the upper feeding seat, so that the wire can be clamped and positioned in advance by the terminal positioning clamp, and then the wire can be inserted into the corresponding mold strip insertion hole by the feeding drive mechanism. There is no need to directly insert the terminal into the mold strip insertion hole. The terminal of the wire is placed in the terminal positioning clamp when the terminal positioning clamp is open, which has a higher fault tolerance rate, thereby improving the efficiency and production quality of wire injection molding production.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Therefore, any modification, equivalent replacement, improvement, etc. made to the above embodiment based on the technical practice of the present invention still falls within the scope of the technical solution of the present invention.
