Abstract
Description
Technical Field
[0001] This utility model relates to the field of PIN needle processing technology, and in particular to an automatic PIN needle removal mechanism for a slider. Background Technology
[0002] Automatic pin insertion lines typically use slider (also known as insert) fixtures for pin insertion. Currently, the pin cleaning process on these automatic lines often involves manually removing the pins from the slider. However, this manual method is inefficient and costly. Furthermore, it cannot prevent human error from causing incomplete pin cleaning, which increases maintenance costs. Utility Model Content
[0003] The main technical problem solved by this utility model is to provide an automatic PIN removal mechanism for a slider, which can automatically remove the PINs in the slider.
[0004] To solve the above-mentioned technical problems, the present invention provides a sliding block PIN removal mechanism, comprising: a base and a support flap and a support side plate disposed on the base. The support flap is disposed on the support side plate and is used to support the sliding block carrying the PIN to be cleaned. A pull plate is provided on one side of the support flap, and the pull plate has a pull hole. The pull hole cooperates with the PIN so that one end of the PIN is in the pull hole. A reciprocating drive is connected to one side of the pull plate to enable the pull plate to move back and forth, so that the pull plate is displaced and the PIN is pulled out of the sliding block through the pull hole.
[0005] Preferably, a support frame is provided on the lower side of the pull plate, the pull plate and the support frame are slidably engaged, and the reciprocating drive component is provided on the support frame.
[0006] Preferably, a receiving plate is provided below the pull hole, and a collection box is connected to the end of the receiving plate.
[0007] Preferably, the support flap is rotatably engaged with the support side plate, and the support flap is connected to a flipping drive assembly that drives it to flip on the support side plate.
[0008] Preferably, the flipping drive assembly includes a flipping drive component, a rack, and a gear. The gear is fixedly connected to the supporting flap, the rack meshes with the gear, and the rack slides with the base. The flipping drive component is mounted on the base and connected to the rack, and is used to drive the reciprocating motion of the rack to flip the supporting flap.
[0009] Preferably, the support flap is provided with a plurality of positioning pins that cooperate with the slider. The positioning pins are matched with the positioning holes on the support flap to stabilize the position of the slider on the support flap.
[0010] Preferably, the pull plate is provided with a sub-plate, which has a sub-hole that mates with the outer pin in the slider, so that the outer pin is locked in the sub-hole.
[0011] The beneficial effects of this utility model are: the slider is supported by a supporting flap, and the bent part with one end outside the slider is inserted into the pull hole. Under the pull of the reciprocating drive, the pull hole is made to abut against the pin and finally the pin is pulled out of the slider, thereby completing the automatic removal of the pin from the slider.

[0029] Example:
[0030] refer to Figure 1 and Figure 2 An automatic PIN removal mechanism for a slider includes: a base 1 and a support flap 11 and a support side plate 12 mounted on the base 1. The support flap 11 is mounted on the support side plate 12 and supports a slider 2 carrying PINs to be cleaned, allowing the slider 2 to be placed on the support flap 11. A pull plate 31 is arranged on one side of the support flap 11, and the pull plate 31 has a pull hole 32. The pull hole 32 cooperates with the PIN so that one end of the PIN is stuck in the pull hole 32. A reciprocating drive 4 is connected to one side of the pull plate 31, enabling the pull plate 31 to move back and forth. This displacement causes one end of the PIN at a bend to abut against the edge of the pull hole 32. Then, under the pull of the reciprocating drive 4, the PIN is pulled through the pull hole 32 and pulled out of the slider 2, thereby removing the PINs from the slider 2. The reciprocating drive 4 can be a cylinder.
[0031] refer to Figure 1 and Figure 2 A support frame 5 is arranged on the lower side of the pull plate 31, so that the pull plate 31 and the support frame 5 slide together, and the support frame 5 supports the position of the pull plate 31. The reciprocating drive 4 is bolted to the support frame 5, and the piston rod of the reciprocating drive 4 is connected to the pull plate 31, so that the reciprocating drive 4 controls the position of the pull plate 31. When the reciprocating drive 4 pulls the pull plate 31, the edge of the pull hole 32 abuts against the bent end of the pin and pulls the pin out of the slider 2.
[0032] refer to Figure 1 A receiving plate 61 is arranged below the pull hole 32. The end of the receiving plate 61 is connected to the collection box 62, so that the removed pins pulled out from the slider 2 fall directly onto the receiving plate 61 and slide into the collection box 62, thus facilitating the collection of the removed pins.
[0033] refer to Figure 1 and Figure 2 To facilitate the mechanical gripper placing the slider 2 onto the support flip plate 11, and to prevent the pins on the slider 2 from colliding with the pull plate 31 when the mechanical gripper places the slider 2, the support flip plate 11 is connected to a flip drive assembly that drives it to flip on the support side plate 12. Before flipping, the support flip plate 11 is in a vertical position, which is in a waiting position. To prevent the slider 2 from falling off the support flip plate 11 in the waiting position, multiple positioning pins 14 that cooperate with the slider 2 are fixed on the support flip plate 11. The positioning pins 14 and the positioning holes on the slider 2 are matched to stabilize the position of the slider 2 on the support flip plate 11. When the mechanical gripper places the slider 2 on the support flip plate 11, it inserts the slider 2 into the positioning pins 14 on the support flip plate 11 through the positioning holes on the slider 2, thereby hanging the slider 2 on the support flip plate 11 to prevent the slider 2 from falling, and also stabilizing and accurately positioning the slider 2 on the support flip plate 11. When it is necessary to remove the pins from slider 2, the flip drive assembly drives the support flap 11 to flip to a horizontal position. The bent end of the pin is then positioned within the pull hole 32. At this point, the reciprocating drive 4 pulls the pull plate 31, thus pulling the pin out of slider 2 in one go, completing the removal of the pins. The horizontal support flap 11 is in the working position. Alternatively, the support flap 11 in the waiting position may not be in a 90-degree vertical position; it can be slightly flipped at a small angle to further ensure that slider 2 does not fall off the support flap 11. The flip drive 71 can be a cylinder.
[0034] refer to Figure 1 and Figure 2 For the slider 2 with double-layer pins, a secondary plate 33 can be bolted to the pull plate 31. The secondary plate 33 has a secondary hole 34 that mates with the outer layer pins in the slider 2, so that the outer layer pins are stuck in the secondary hole 34. The process of removing the outer layer pins is the same as described above. The secondary hole 34 is through the pull hole 32, so the outer layer pins on the slider 2 can also fall directly onto the receiving plate 61 and enter the collection box 62.
[0035] refer to Figure 1 and Figure 2The flipping drive assembly includes a flipping drive component 71, a rack 72, and a gear 73. The gear 73 is fixedly connected to the support flap 11. A connecting plate 13 can be bolted to the lower side of the support flap 11. A rotating shaft 74 is installed on the connecting plate 13 and the support side plate 12. The support side plate 12 is connected to the mounting shaft 74 through a bearing. The connecting plate 13 is fixedly connected to the rotating shaft 74. The gear 73 is fixedly connected to the rotating shaft 74. The rack 72 meshes with the gear 73 and slides with the base 1. The flipping drive component 71 is bolted to the base 1 and connected to the rack 72, thereby driving the reciprocating motion of the rack 72 to flip the support flap 11.
[0036] Operating Process: Initially, the support flap 11 is in a vertical position. The mechanical gripper places the slider 2, from which the pins need to be removed, onto the vertical support flap 11 and stabilizes the slider 2 on the support flap 11 using the positioning pin 14. Then, the flip drive 71 moves, driving the rack 72 to move. The rack 72 moves, driving the gear 73 to rotate. Simultaneously, the support flap 11 rotates with the gear 73, moving from a vertical position to a horizontal position. At this point, one end of the pin is inserted into the pull hole 32 and / or the secondary hole 34. Then, the reciprocating drive 4 moves the pull plate 31 away from the support flap 11. During the movement, the edges of the pull hole 32 and / or the secondary hole 34 begin to abut against the bent part of the pin, pulling the pin out of the slider 2, thus removing the pins from the slider 2. The pins then fall onto the receiving plate 61 and into the collection box 62. The reciprocating drive 4 and the flip drive 71 then reset, starting the next cycle.
