[0018] The Z-shaped pin clamping spring is arranged on the inner wall surface of the left clamping jaw.

[0019] The vertical avoidance spring is arranged on the top of the left clamping jaw.

[0020] The left clamping jaw telescopic mechanism can control the height telescopic of the left clamping jaw.

[0021] The Z-shaped pin clamping spring piece and the vertical avoidance spring piece are integrally arranged to form an L-shaped structure; the bottom of the Z-shaped pin clamping spring piece is bent toward the left clamping claw.

[0022] A Z-shaped press-fit avoidance groove is arranged at the outer bottom of the right clamping jaw, and the top surface of the Z-shaped press-fit avoidance groove is formed as a press-fit height limiting portion.

[0023] An inverted cone-shaped guide groove is arranged on the top of the Z-shaped pin elastic positioning groove.

[0024] The Z-type pin positioning tooling comprises a supporting bottom plate, an elastic positioning plate and an upper positioning plate which are horizontally arranged in sequence from bottom to top.

[0025] The inverted cone guide groove is arranged on the upper positioning plate, and the bottom of the outer wall surface of the inverted cone guide groove extends downward to form a lower guide plate.

[0026] The elastic positioning plate can be elastically extended and retracted horizontally, and the Z-shaped pin elastic positioning groove is formed between the elastic positioning plate and the lower guide plate.

[0027] The supporting bottom plate is used to support the elastic positioning plate and can extend into the cavity of the Z-shaped shell.

[0028] The top surface of the upper positioning plate located on the left side of the inverted cone-shaped guide groove is formed as a left clamping claw blocking surface.

[0029] The Z-type pin positioning tool also includes a discharge assembly arranged on the Z-type shell lifting and clamping plate, which is used to assist in the separation and removal of the Z-type pin elastic positioning groove and the Z-type pin.

[0030] A Z-type pin automatic positioning and pressing method comprises the following steps.

[0031] Step 1, Z-type pin feeding: At the Z-type pin loading station, there are N Z-type pins equal to the number of Z-type pin holes in the Z-type housing, and each Z-type pin is placed vertically, and the electrical interface of each Z-type pin is exposed at the top.

[0032] Step 2: Press-fit the clamping jaws to load the material, specifically including the following steps:

[0033] Step 2-1, resetting the left clamping jaw: the telescopic mechanism of the left clamping jaw in the left clamping jaw of the press-fit clamping jaw is activated, so that the bottom surface of the left clamping jaw is kept flush with the bottom surface of the right clamping jaw and is not affected by the elastic force of the vertical avoidance spring.

[0034] Step 2-2, the press-fitting jaws slide: the press-fitting jaws slide to the Z-type pin loading station.

[0035] Step 2-3, loading the press-fitting jaws: the height of the press-fitting jaws is lowered so that the electrical interface parts of the N Z-type pins are all extended into the Z-type pin placement groove to a set depth; at this time, the Z-type pins located in the Z-type pin placement groove are in a clamped state under the elastic force of the Z-type pin clamping spring.

[0036] Step 2-4, reset the press-fitting jaws: the press-fitting jaws rise in height and slide to the Z-type pin press-fitting station.

[0037] Step 3, Z-shaped shell pressing: The height of the Z-shaped shell lifting and pressing plate is lowered to press and position the top surface of the Z-shaped shell located below.

[0038] Step 4: Press-fit the Z-type pins once: The height of the press-fitting jaws is lowered as a whole, and the plug-in portion of each Z-type pin passes through the vertical press-fitting groove and the Z-type pin elastic positioning groove in sequence and enters the corresponding Z-type pin hole.

[0039] Step 5: Secondary press-fitting of the Z-type pin, including the following steps:

[0040] Step 5-1, blocking with the left jaw: the height of the press-fit jaw continues to drop, and the left jaw is blocked by the Z-type pin positioning tooling located outside the Z-type pin elastic positioning groove. At this time, the left jaw retracting mechanism releases the drive to the left jaw, and the left jaw can freely retract and retract under the action of the vertical avoidance spring.

[0041] Step 5-2, adjust the width of the Z-type pin elastic positioning groove: the height of the press-fitting jaw continues to drop again, vertically avoiding the compression of the spring sheet, and the right jaw carries the Z-type pin to drop in height and enters the Z-type pin elastic positioning groove. The width of the Z-type pin elastic positioning groove increases to facilitate the press-fitting insertion part of the right jaw and the Z-type pin to pass through at the same time, until the Z-type pin is inserted into the corresponding Z-type pin hole to the set position, thereby completing the pin press-fitting of the Z-type housing; at this time, each Z-type pin is clamped with the corresponding Z-type pin hole through the barb.

[0042] Step 6: Reset the Z-type pin press-fit assembly: The height of the press-fit jaws rises as a whole and resets, and the Z-type pin placement slot is disengaged from all Z-type pins; at this time, the vertical avoidance spring is reset to make the bottom surface of the left jaw flush with the bottom surface of the right jaw.

[0043] Step 7, reset the Z-type shell lifting and clamping plate: the Z-type shell lifting and clamping plate carrying the Z-type pin positioning tooling rises synchronously and resets; during the rising process of the Z-type pin positioning tooling, the Z-type pin elastic positioning groove is separated from all Z-type pins; at this time, the width of the Z-type pin elastic positioning groove is also adaptively reduced and reset.

[0044] Step 8: Take out the Z-shaped shell that has been pressed at the Z-shaped pin pressing station and put it into a new Z-shaped shell to be pressed, and repeat steps 1 to 8 to complete the pressing of the Z-shaped pin in the next Z-shaped shell.

[0045] In step 5-1, when the left jaw contacts the left jaw blocking surface, the left jaw telescopic mechanism releases the drive on the left jaw, and the maximum compression stroke of the vertical avoidance spring is not less than the secondary pressing stroke of the Z-type pin.

[0046] In step 7, before the Z-shaped shell lifting and clamping plate rises, the unloading assembly arranged on the Z-shaped shell lifting and clamping plate extends out and presses against the top surface or inner cavity of the Z-shaped shell, so as to facilitate the separation and removal of the Z-shaped pin elastic positioning groove and the Z-shaped pin.

[0047] The present invention has the following beneficial effects: the Z-type housing lifting and clamping plate in the present invention can clamp the Z-type housing to be press-fitted with pins, which is convenient for the subsequent press-fitting of Z-type pins; the Z-type pin press-fitting assembly can automatically grab multiple Z-type pins and preliminarily position them, and can also carry multiple positioned Z-type pins through the Z-type pin elastic positioning groove of the Z-type pin positioning tooling for primary and secondary press-fitting. During the press-fitting process, the Z-type pin elastic positioning groove can adaptively adjust the width, thereby ensuring that the Z-type pin is prevented from deforming during press-fitting, thereby ensuring the assembly accuracy and success rate. In addition, all Z-type pins are press-fitted synchronously at one time, so that the press-fitting consistency is high and the qualified rate is high. BRIEF DESCRIPTION OF THE DRAWINGS

8. A Z-type pin automatic positioning and pressing method, characterized in that: The steps include: Step 1, Z-type pin feeding: at the Z-type pin feeding station, there are N Z-type pins equal to the number of Z-type pin holes in the Z-type housing, and each Z-type pin is placed vertically, and the electrical interface of each Z-type pin is exposed at the top; Step 2: Press-fit the clamping jaws to load the material, specifically including the following steps: Step 2-1, resetting the left clamping jaw: the telescopic mechanism of the left clamping jaw in the left clamping jaw of the press-fit clamping jaw is activated, so that the bottom surface of the left clamping jaw is kept flush with the bottom surface of the right clamping jaw and is not affected by the elastic force of the vertical avoidance spring; Step 2-2, the press-fitting jaws slide: the press-fitting jaws slide to the Z-type pin loading station; Step 2-3, loading the press-fitting jaws: the height of the press-fitting jaws is lowered so that the electrical interface parts of the N Z-type pins are all inserted into the Z-type pin placement groove to a set depth; at this time, the Z-type pins located in the Z-type pin placement groove are in a clamped state under the elastic force of the Z-type pin clamping spring sheet; Step 2-4, reset the press-fitting jaws: the press-fitting jaws rise in height and slide to the Z-type pin press-fitting station; Step 3, Z-shaped shell pressing: the height of the Z-shaped shell lifting and pressing plate is lowered to press and position the top surface of the Z-shaped shell located below; Step 4: Press-fit the Z-type pins once: the height of the press-fitting jaws is lowered as a whole, and the plug-in portion of each Z-type pin passes through the vertical press-fitting groove and the Z-type pin elastic positioning groove in sequence and enters the corresponding Z-type pin hole; Step 5: Secondary press-fitting of the Z-type pin, including the following steps: Step 5-1, blocking with the left clamp: the height of the press-fit clamp continues to drop, and the left clamp is blocked by the Z-type pin positioning tooling located outside the Z-type pin elastic positioning groove. At this time, the left clamp telescopic mechanism releases the drive to the left clamp, and the left clamp can freely extend and retract under the action of the vertical avoidance spring; Step 5-2, adjust the width of the Z-type pin elastic positioning groove: the height of the press-fitting clamping jaw continues to drop again, vertically avoiding the compression of the spring sheet, and the right clamping jaw carries the Z-type pin to drop in height and enter the Z-type pin elastic positioning groove. The width of the Z-type pin elastic positioning groove increases, which is convenient for the press-fitting insertion part of the right clamping jaw and the Z-type pin to pass through at the same time, until the Z-type pin is inserted into the corresponding Z-type pin hole to the set position, thereby completing the pin press-fitting of the Z-type housing; at this time, each Z-type pin is clamped with the corresponding Z-type pin hole through the barb; Step 6: Reset the Z-type pin press-fit assembly: The height of the press-fit clamping jaws rises as a whole and resets, and the Z-type pin placement slots are separated from all Z-type pins; at this time, the vertical avoidance spring is reset to make the bottom surface of the left clamping jaw flush with the bottom surface of the right clamping jaw; Step 7, reset the Z-shaped shell lifting and clamping plate: the Z-shaped shell lifting and clamping plate carrying the Z-shaped pin positioning tooling rises synchronously and resets; during the rising process of the Z-shaped pin positioning tooling, the Z-shaped pin elastic positioning groove is separated from all Z-shaped pins; at this time, the width of the Z-shaped pin elastic positioning groove is also adaptively reduced and reset; Step 8: Take out the Z-shaped shell that has been pressed at the Z-shaped pin pressing station and put it into a new Z-shaped shell to be pressed, and repeat steps 1 to 8 to complete the pressing of the Z-shaped pin in the next Z-shaped shell.

9. The Z-type pin automatic positioning and pressing method according to claim 8, characterized in that: In step 5-1, when the left jaw contacts the left jaw blocking surface, the left jaw telescopic mechanism releases the drive on the left jaw, and the maximum compression stroke of the vertical avoidance spring is not less than the secondary pressing stroke of the Z-type pin.

10. The Z-type pin automatic positioning and press-fitting method according to claim 8, characterized in that: In step 7, before the Z-shaped shell lifting and clamping plate rises, the unloading assembly arranged on the Z-shaped shell lifting and clamping plate extends out and presses against the top surface or inner cavity of the Z-shaped shell, so as to facilitate the separation and removal of the Z-shaped pin elastic positioning groove and the Z-shaped pin.
