[0034] Working principle: the existing carrier tape processing device in the carrier tape is punched and formed in two sections, and then the relative position of the cavity and the hole after forming is easy to produce deviation, which leads to low precision of the processed carrier tape. A row of holes is cut in the middle of the upper cover plate A, the punch pin C is inserted into the hole, the upper pressure pin plate B is pressed, the screw is locked, the forming upper die K is installed at the bottom of the upper cover plate A, and two positioning pins are positioned, and then two screws are locked. The cylinder connects the upper cover plate A to drive the punch pin C and the forming upper die K to move synchronously. The forming lower die L is installed at the bottom of the base, and the cylinder connects the guide rod J to drive the forming lower die L to move up and down. The material belt is pulled into the mechanism, the punch pin C first punches the hole of the material belt, and at the same time the forming upper die K is pressed to the position, the forming lower die L rises to the set position at the same time the forming upper die K is pressed, and the forming lower die L blows to complete the forming. (According to the needs of the carrier tape product, determine whether to blow), after the forming upper die K and the forming lower die L are combined to form, they are separated respectively to return to the original position, completing a forming cycle.

[0035] When the pressure pin plate B and the upper cover plate A are connected, the pressure pin plate B is first inserted into the groove on the upper cover plate A from front to back. In the process of inserting the pressure pin plate B, the inner wall of the upper cover plate A extrudes the inclined surface on the fixed block 43, so that the fixed block 43 moves to the inside of the fixed cavity 41 under the action of the extrusion force and extrudes the fixed spring 42, so that the fixed spring 42 is elastically deformed. When the pressure pin plate B is completely fitted with the upper cover plate A, the extrusion force of the inner wall of the upper cover plate A on the fixed block 43 disappears, and at this time the fixed block 43 restores to the original position under the restoring force of the fixed spring 42 and is clamped with the fixed groove 44, which has the effect of limiting the pressure pin plate B and fixing the connection between the pressure pin plate B and the upper cover plate A. When the connection between the pressure pin plate B and the upper cover plate A is to be released, the pressure pin plate B is only pulled from back to front, so that the pressure pin plate B and the upper cover plate A are separated.

[0036] When the fixed block 43 moves, the sliding block 45 fixedly connected with the fixed block 43 synchronously slides in the sliding groove 46, which has the effect of limiting the movement distance of the fixed block 43, avoiding the fixed block 43 from moving excessively and coming out of the fixed cavity 41 under the restoring force of the fixed spring 42.

[0037] When the pressing needle plate B is inserted into the slot of the upper cover plate A from front to back, the positioning block 47 is inserted into the positioning slot 48, the insertion depth of the pressing needle plate B is limited by the cooperation between the positioning block 47 and the positioning slot 48, when the positioning block 47 is inserted into the positioning slot 48, the inner wall of the positioning slot 48 extrudes the arc surface of the connecting block 52, the connecting block 52 moves into the connecting cavity 49 under the extrusion force, and the connecting spring 51 is extruded, so that the connecting spring 51 is elastically deformed, when the positioning block 47 is inserted into the positioning slot 48 to the limit, the extrusion force of the connecting block 52 disappears, at this time, the connecting block 52 is restored to the original position under the restoring force of the connecting spring 51 and is clamped with the connecting slot 53, which has the effect of auxiliary fixing the connection between the pressing needle plate B and the upper cover plate A.

[0038] When the pressing needle plate B is inserted into the slot of the upper cover plate A from front to back, the positioning block 47 is inserted into the positioning slot 48, at this time, the positioning block 47 extrudes the clamping block 56 made of rubber material on the inner wall of the positioning slot 48, so that the clamping block 56 is elastically deformed, when the positioning block 47 is inserted into the positioning slot 48 to the limit, the extrusion force of the clamping block 56 disappears, at this time, the clamping block 56 is restored to the original state under the restoring force of itself and is clamped with the positioning block 47, which has the effect of limiting the positioning block 47.

[0039] When the connecting block 52 moves, the limiting block 54 fixedly connected with the connecting block 52 slides in the limiting slot 55, the moving distance of the connecting block 52 is limited by the combination of the limiting block 54 and the limiting slot 55, which avoids the connecting block 52 from being pulled out of the connecting cavity 49 due to excessive movement under the restoring force of the connecting spring 51.
