[0002] Pin header connectors are widely used in electronic devices, mainly in electronic devices such as liquid crystal displays, scanners, mobile phones, and tablet computers, to achieve signal connection or transmission between various functional modules within such devices or with external devices. Currently, connector manufacturers mostly use automatic pin insertion machines to automatically assemble and produce connectors. During the connector production process, after the pin terminal strips are cut, the ends of the pin terminals are still connected to the material pins. The presence of the material pins will affect the normal use of the connector, so the material pins need to be removed. However, most existing pin insertion machines lack a mechanism to automatically scrape off the material pins. Usually, the material pins connected to the pin terminals must be manually broken off with the help of tooling. This operation is time-consuming, labor-intensive, and inefficient.

[0025] Reference Figures 1 to 7 The embodiments of the present invention are further described.

[0026] The flip scraper mechanism in this embodiment is installed at the output end of the pin insertion machine, and is used to scrape off and remove the material pins 5 at the outer ends of the terminals on the connector. The flip scraper mechanism includes a base 11, a moving block 2, a flip seat 1 and a driving mechanism 144, wherein the connecting block 2 is used to position the connector housing on the pin insertion machine, and to drive the connector housing to move by controlling the movement of the connecting block 2. During the movement, the terminal is inserted into the connector housing through the terminal insertion mechanism; the flip scraper mechanism can directly cooperate with the moving block 2, so that after the pin terminal is inserted, the moving block 2 carrying the connector is directly moved to the flip scraper mechanism to scrape off and remove the material pins 5 at the end of the pin terminal. Specifically, a connector positioning groove for positioning the connector is formed on the moving block 2, and the moving block 2 is slidably connected to the flip seat 1. One end of the flip seat is flipably mounted on the base 11 through a rotating shaft, and a first gear 141 is fixed on the rotating shaft. The base 11 is also provided with a second gear 141 that engages with the first gear 141. The second gear 142 and the sliding block 51 fixed on the base 11, the sliding block 51 is located below the second gear 142 and a sliding groove 52 is formed on the sliding block 51, and a rack 143 connected to the second driving mechanism 144 is slidingly provided in the sliding groove 52, and the sliding groove 52 is used to guide and limit the rack 143, and the second driving mechanism 144 can be a cylinder. The second driving mechanism 144 drives the rack 143 to move and drives the flip seat 1 to flip relative to the base 11 under the meshing transmission of the first gear 141 and the second gear 142, so that the flip seat 1 is moved to the scraping position for scraping. After the scraping is completed, the flip seat 1 is driven to flip and reset relative to the base 11. After the flip seat 1 is in the scraping position, the material foot 5 positioned on the connector of the moving block 2 is facing downward, so that the material foot 5 can be quickly detached from the connector after being scraped off.

[0027] Reference Attachment Figure 1 、 2, 5. A first limit block 12 and a second limit block 13 are provided on opposite sides of the flip seat 1, and a positioning gap 14 for positioning the moving block 2 is formed between the first limit block 12 and the second limit block 13. A limiting protrusion 115 is protruded from the upper ends of the first limit block 12 and the second limit block 13. When the moving block 2 moves into the positioning gap 14 of the flip seat 1, the limiting protrusion 115 can abut and limit the connector on the moving block 2 from disengaging from the connector positioning groove. At the same time, the second limit block 13 includes a bottom block 133 and a limiting plate 134. The limiting plate 134 is installed on the bottom block 133. A waist-shaped hole 136 is provided on the limiting plate 134. The bottom block 133 is provided with a locking hole that cooperates with the waist-shaped hole 136 to fix the limiting plate 134. The fixing screw passes through the waist-shaped hole 136 and cooperates with the locking hole to fix the limiting plate 134 on the bottom block 133.

[0028] Reference Attachment Figure 5 、 6 , 7. The bottoms of the first limit block 12 and the second limit block 13 are recessed with a limit groove 116 connected to the positioning gap 14, and the two ends of the bottom of the moving block 2 protrude with sliding protrusions that slide in the limit groove 116. The bottom surface of the positioning gap 14 on the flip seat 1 is provided with a third limit block 121 and a clamping block 122. A clamping groove 21 is formed on the bottom of the moving block 2. When the moving block 2 moves from a port on one side of the positioning gap 14 to the positioning gap 14, the third limit block 121 enters the clamping groove 21 and is clamped to the bottom of the moving block 2 by the clamping block 122 to position the moving block 2. A compression spring is provided at the bottom of the clamping block 122, and the compression spring provides an upward pressing force for the clamping block 122 under the elastic force of the compression spring, so that the clamping block 122 is upwardly pressed against the moving block 2. Guide slopes are formed at both ends of the clamping block 122, which can guide the sliding moving block 2 to facilitate the clamping block 122 to clamp the moving block 2.

[0029] Reference Attachment Figure 2 The scraper unit 3 includes a scraper 31 and a driving mechanism 32. The driving mechanism 32 is a cylinder. The scraper 31 is connected and fixed to the output end of the driving mechanism 32. After the flip seat 1 is flipped, the connector positioning groove of the moving block 2 is facing downward (so that the material pin 5 on the connector is facing downward). When the driving mechanism 32 drives the scraper 31 to reciprocate along the axial direction of the rotating shaft, it applies lateral force to the material pin 5 on the connector, so that the material pin 5 is disconnected from the pin terminal on the connector and falls off.

[0030] Reference Attachment Figure 3 、 4, further includes a driving mechanism three 4 and a fixed seat 41, the fixed seat 41 is relatively fixed to the base 11, the driving mechanism three 4 is connected to the fixed seat 41, the driving mechanism three 4 is on the side of the flip seat 1, the driving mechanism three 4 can be a cylinder and the output end of the driving mechanism three 4 is provided with a plurality of push rods 42, each push rod 42 is provided with a spring 43 connected to the output end of the driving mechanism three 4, and the flip seat 1 is provided with a card hole 44 corresponding to the push rod 43. After the flip seat 1 is flipped, the card hole 44 is aligned with the push rod 42, and the driving mechanism three 4 drives the push rod 42 to pass through the card hole 44 and extend into the connector positioning groove to abut the connector, thereby playing a better positioning role for the connector; specifically, the card hole 44 is provided on the first limit block 12. After the flip seat 1 is flipped, the spring 43 is provided to form an elastic connection between the push rod 42 and the output end of the driving mechanism three 4, thereby preventing the connector from being damaged by excessive pressure from the push rod 42.

[0031] Furthermore, a limiting seat 7 is provided at the output end of the driving mechanism three 4, and the push rod 42 is installed on the limiting seat 7. A limiting edge 71 corresponding to the push rod 42 is protruded on the limiting seat 7, and a limiting groove is provided on the push rod 42 for sliding with the limiting seat 7. The cooperation between the limiting edge 71 and the limiting groove can play a guiding and limiting role to ensure the position accuracy of the push rod 42, thereby making the push rod 42 move along the predetermined direction (the length direction of the limiting edge 71).

[0032] A locking block 45 is fixed to the output end of the driving mechanism three 4, and a positioning block 46 is fixed to the base 11. When the flip seat 1 flips to the scraping position, the positioning block 46 supports the flip seat 1 upward, and while the driving mechanism three 4 drives the push rod 42 to be inserted into the card hole 44, the locking block 45 moves accordingly, and the locking block 45 contacts the upper part of the flip seat 1 to limit the flip seat 1 downward. In this way, the cooperation of the positioning block 46 and the locking block 45 can reliably position the flip seat 1, thereby ensuring the stability of the flip seat 1 during scraping.

[0033] Reference Attachment Figure 1 、 2 , and also includes a driving mechanism four 6, which can be a cylinder. A driving rod 61 is provided on the driving mechanism four 6. After the scraping is completed, the driving mechanism four 6 drives the driving rod 61 to extend and eject the moving block 2 from the positioning gap of the flip seat 1.

[0034] When the pin insertion machine with the flipping scraping mechanism is working, the pin terminal is plugged into the connector, and the connector is positioned on the moving block 2 and moves along the conveying track. When the moving block moves to the flip seat 1, the moving block 2 is pushed from the conveying track into the positioning gap of the flip seat 1 through the ejecting mechanism (such as a cylinder). The driving mechanism 2 144 drives the flip seat 1 to rotate to the scraping position, and the driving mechanism 3 4 drives the ejector rod 42 to abut against the connector on the moving block 2. At the same time, the locking block 45 abuts against the upper part of the flip seat 1 and cooperates with the positioning block 46 to position the flip seat 1, and then the driving mechanism 1 32 drives the scraper 31 to move back and forth to scrape off the material feet 5 on the connector. After the scraping is completed, the driving mechanism 3 4 drives the ejector rod 42 and the locking block 45 to reset, and the driving mechanism 2 144 drives the flip seat 1 to flip and reset. Finally, the driving mechanism 4 6 drives the driving rod 61 to make the moving block 2 withdraw from the flip seat 1 and return to the conveying track of the pin insertion machine.
