Technical Field

[0001] The invention relates to the technical field of PIN implantation, and in particular to a multi-layer PIN stacking gripper. Background Art

[0002] PIN pins are a type of metal material used in connectors to conduct electricity (signals). PIN pins are primarily produced by stamping metal sheets, placing them into a mold through an implantation device (gripper), and then injection molding to form a complete product. Complex products often require multiple layers of PIN pins to be stacked, reducing the size of the molded product while adapting to complex tasks.

[0003] According to Chinese patent CN218753504U, a PIN needle automatic feeding device is disclosed, which includes a base plate, a support platform, a material dividing assembly, a servo Y-axis moving carrier, and a swinging assembly; the material dividing assembly is provided with a feeding table and a material dividing gripper, and the servo Y-axis moving carrier drives the material dividing gripper to move, and the PIN needle enters the material dividing assembly through the feeding table, and the material dividing gripper grabs the PIN needle and places it on the swinging assembly. When the ordered product is more complex, such as the PIN needles need to be stacked, the material dividing gripper needs to travel back and forth between the material dividing assembly and the swinging assembly multiple times, and the moving distances are different, which increases the moving distance of the moving carrier and reduces the grabbing efficiency.

[0004] Therefore, it is necessary to develop a multi-layer PIN stacking gripper to solve the above problems. Utility Model Content

[0008] The second clamp has a second receiving groove formed inwardly from a surface thereof, the second receiving groove is used to receive a PIN, and the height of the second receiving groove receiving the PIN is greater or less than the height of the first receiving groove receiving the PIN.

[0009] Furthermore, the fixing clamp arm also has a through hole, and the through hole passes through both side surfaces of the fixing clamp arm.

[0010] Furthermore, the number of the first receiving grooves is changed according to needs, and is distributed from one side of the fixed clamp arm to the other side thereof at intervals, and the through hole passes through and connects the plurality of first receiving grooves in sequence.

[0011] Furthermore, the movable clamping arm can enter the through hole from the side of the fixed clamping arm.

[0012] Furthermore, the movable clamping arm has an empty slot formed by being recessed inward from the end surface. The number of the empty slots changes according to demand and is distributed from one end of the movable clamping arm to the other end, and is the same as the number of the first receiving slots and corresponds one by one.

[0013] Furthermore, the fixed clamp arm also has a receiving groove, which is located on one side of the first receiving groove and is distributed from one side of the fixed clamp arm to the other side thereof, and is on the same horizontal line as the first receiving groove and corresponds one by one.

[0014] Furthermore, the second clamp is arranged opposite to the first clamp and has the same structure.

[0015] Furthermore, the movable clamping arm has a limiting groove, which is formed by a horizontal depression from the inner wall of the empty slot and is used to limit the position of the PIN when clamping the PIN.

[0016] Furthermore, the limiting grooves are respectively located at the upper and lower ends of the empty slot.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Please see Figures 1 to 6 The utility model is a multi-layer PIN stacking gripper, which includes a mounting frame 1, a fixing plate 2 docked with the mounting frame 1, a driving part 3 installed on the mounting frame 1 and the fixing plate 2, a first clamp 4 and a second clamp 5 pushed by the driving part 3.

[0028] Please see Figure 1The mounting frame 1 is used to support the fixed plate 2, the driving part 3, the first clamp 4 and the second clamp 5 pushed by the driving part 3. The mounting frame 1 includes several driving cylinders 11 fixedly mounted thereon and a push plate 12 driven by the several driving cylinders 11. The push plate 12 is located outside the mounting frame 1. The driving cylinder 11 can push the push plate 12 close to or away from the mounting frame 1.

[0029] Please see Figures 1 to 2 The fixed plate 2 is located on the outside of the push plate 12 and is arranged parallel to the push plate 12. A support rod 21 is installed between the fixed plate 2 and the push plate 12. One end of the support rod 21 is connected to the fixed plate 2, and the other end is connected to the push plate 12 to ensure the distance between the fixed plate 2 and the push plate 12. The fixed plate 2 has a plurality of slots 22. The plurality of slots 22 pass through the upper and lower surfaces of the fixed plate 2 and are arranged in sequence from one end of the fixed plate 2 to the other end. The first clamp 4 and the second clamp 5 both pass through the slots 22.

[0030] Please see Figure 2 The driving part 3 is arranged between the fixed plate 2 and the pushing plate 12, and includes a base 31, a track 32 arranged on the base 31, and a mounting plate 33 that moves along the track 32. The bottom surface of the base 31 is in contact with the surface of the fixed plate 2 and is fixedly connected. Its two ends are recessed inward from the end surface to form an air avoidance groove 311, and a limit member 312 is provided in the air avoidance groove 311. The limit member 312 is provided with a spherical protrusion 313 on the side opposite to the air avoidance groove 311, and the spherical protrusion 313 can be abutted against the inner surface of the air avoidance groove 311 formed by the base 31. When the mounting frame 1 moves, the base 31 is in a non-parallel state, and the base 31 presses the limit member 312. The limit member 312 abuts against the base 31 through the spherical protrusion 313, so that the base 31 does not have a large displacement.

[0031] The track 32 extends from one end of the base plate 31 to the other end thereof. The mounting plate 33 is provided with a slider 331, which is movably connected to the track 32 via the slider 331. The driving portion 3 is further provided with a movable driving member 34. The movable driving member 34 is a certain type of cylinder, which is located on one side of the base plate 31 and is used to push the mounting plate 33 to move along the track 32. The mounting plate 33 has a through groove 332 running through its upper and lower surfaces. The through groove 332 corresponds to the slot 22 and is used for the first clamp 4 and the second clamp 5 to pass through.

[0032] A bracket 35, a pushing drive member 36 installed on the side of the bracket 35, and a movable plate 37 driven by the pushing drive member 36 are installed in the through slot 332. The bracket 35 is fixedly connected to the mounting plate 33. The pushing drive member 36 is located on the inner side of the bracket 35 and extends into the through slot 332. Specifically, the pushing drive member 36 is perpendicular to the mounting plate 33, and a track 32 is installed on its outer surface. The track 32 extends from the top of the pushing drive member 36 to its bottom. The movable plate 37 is installed with a slider 331, which is movably connected to the track 32. The pushing drive member 36 drives the movable plate 37 to move along the track 32.

[0033] Please see Figures 3 to 5 The first clamp 4 includes a clamping base 41, a fixed clamping arm 42 and a movable clamping arm 43 installed on the clamping base 41. The clamping base 41 is fixedly connected to the movable plate 37 and moves synchronously with the movable plate 37. The top of the fixed clamping arm 42 is fixedly connected to the clamping base 41, and its top extends outward and is recessed inward from the end surface to form a first receiving groove 421. The number of the first receiving grooves 421 changes according to needs, and is distributed from one side of the fixed clamping arm 42 to the other side thereof. The fixed clamping arm 42 also has a through hole 422, which passes through the two side surfaces of the fixed clamping arm 42. Specifically, the through hole 422 passes through and connects multiple first receiving grooves 421 in sequence.

[0034] The fixed clamp arm 42 also has a receiving groove 423, which is located on one side of the first receiving groove 421. The receiving groove 423 is distributed from one side of the fixed clamp arm 42 to the other side thereof, and is on the same horizontal line as the first receiving groove 421 and corresponds one by one. The shape of the receiving groove 423 changes according to needs, that is, the shape of the PIN changes. When the fixed clamp arm 42 and the movable clamp arm 43 clamp the PIN, the PIN enters the receiving groove 423 and the first receiving groove 421.

[0035] The movable clamping arm 43 has an empty slot 431 formed by being recessed inward from the end surface. The number of the empty slots 431 can be changed according to demand and is distributed at intervals from one end of the movable clamping arm 43 to the other end. The specific number of the empty slots 431 is the same as the number of the first receiving slots 421 and corresponds one by one. The movable clamping arm 43 can enter the through hole 422 from the side of the fixed clamping arm 42. When the PIN is not needed to be clamped, the empty slot 431 coincides with the first receiving slot 421, and the PIN enters the first receiving slot 421. When the PIN is clamped, the empty slot 431 enters between adjacent first receiving slots 421, and the movable clamping arm 43 and the fixed clamping arm 42 clamp the PIN.

[0036] The movable clamping arm 43 further includes a movable clamping arm driving component 44 . The movable clamping arm driving component 44 is installed outside the fixed clamping arm 42 and is used to drive the movable clamping arm 43 to move into the fixed clamping arm 42 .

[0037] Please see Figure 6The second clamp 5 is arranged opposite to the first clamp 4 and has the same structure. The second clamp 5 has a second receiving groove 51. The depth of the second receiving groove 51 is greater than or less than the depth of the first receiving groove 421, so that the heights of the PINs clamped by the movable clamping arm 43 and the fixed clamping arm 42 are different.

[0038] The first clamp 4 and the second clamp 5 are both equipped with an ejection part 6, which includes an ejection drive part 61 and a push rod 62 connected to the ejection drive part 61. The ejection drive part 61 is fixedly installed on the clamp base 41. The push rod 62 passes through the fixed clamp arm 42 from the top, and its end extends into the storage groove 423. The ejection drive part 61 can drive the push rod 62 to move to eject the PIN.

[0039] In another embodiment, the movable clamping arm 43 has a limiting groove 432, which is formed by a horizontal depression on the inner wall of the empty slot 431 and is used to limit the position of the PIN when clamping the PIN. Preferably, the limiting groove 432 is respectively located at the upper and lower ends of the empty slot 431.

[0040] When the multi-layer PIN stacking gripper of the present invention is used, the mounting frame 1 is driven by an external driving device to move to a predetermined position, the driving cylinder 11 pushes the fixed plate 2 close to the PIN, and the driving member 36 drives the movable plate 37 to move toward the PIN, and the PIN enters the receiving groove 423 and the first receiving groove 421, the movable clamping arm driving member 44 drives the movable clamping arm 43 to move toward the fixed clamping arm 42, and the empty groove 431 enters between the adjacent first receiving grooves 421, the movable clamping arm 43 and the fixed clamping arm 42 clamp the PIN, the driving member 36 drives the movable plate 37 to move away from the PIN, and the movable driving member 34 drives the movable clamping arm 43 and the fixed clamping arm 42 to move the PIN clamped to other predetermined positions.

[0041] The utility model is a multi-layer PIN stacking gripper with the characteristic of high gripping efficiency. PINs of different heights are gripped by first and second clamps of different heights, thereby shortening the moving distance of the first and second clamps and improving the gripping efficiency.

[0042] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
