Description

Technical Field

[0001] This invention relates to the field of connector manufacturing technology, and specifically to a fully automatic connector pin cutting and bending equipment. Background Technology

[0002] Electrical connectors are generally used to connect two active devices to transmit current or signals, and connector pins are a common component of connectors. With the miniaturization and compactness of electronic products, there are often limitations on the overall height of the product. Straight connector pins are no longer sufficient to meet user needs, and more and more connectors require bent pins. Currently, pin insertion and bending are mostly done manually, wasting manpower and resources, resulting in low production efficiency. Furthermore, when there are many pins, it is difficult to ensure consistency in insertion depth and bending angle, leading to poor product quality. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defects of low production efficiency and poor consistency of connector pins in the prior art, thereby providing a fully automatic connector pin cutting and bending equipment with high production efficiency and good consistency.

[0004] To this end, the present invention provides a fully automatic connector pin cutting and bending device, comprising a frame, a pin strip reel, a connector housing feeding device, a pin cutting mechanism, a pin transfer robot, a pin insertion shaping device, and a pin bending device. The pin strip reel and the connector housing feeding device are disposed on the frame and are adapted to respectively transport the pin strip and the connector housing. The pin cutting mechanism is adapted to cut the edge of the pin strip. The pin transfer robot is adapted to transfer the pin with the cut edge to the pin insertion shaping device. The pin insertion shaping device is adapted to insert the pin into the connector housing and shape the pin. The pin bending device is adapted to bend the pin.

[0005] The pin insertion shaping device includes a pin pre-insertion assembly and a pin insertion shaping assembly. The pin pre-insertion assembly includes a jaw adapted to clamp the pin and a jaw drive adapted to drive the jaw to pre-inserte the pin into the connector housing. The pin insertion shaping assembly is located after the pin pre-insertion assembly and is adapted to insert the pre-inserted pin into place and shape it.

[0006] The pin insertion shaping assembly includes a first pressing block, a first pressing block drive, two shaping blocks, and a shaping block drive. The first pressing block is located on the pin insertion side of the connector housing and has abutment portions corresponding to multiple pins, and first positioning blocks disposed on both sides of the multiple abutment portions. The two first positioning blocks abut against the two sides of the connector housing respectively. The first pressing block drive is connected to the first pressing block and is adapted to drive the first pressing block to move towards or away from the connector housing. The two shaping blocks are located on the pin protrusion side of the connector housing. The two shaping blocks are arranged vertically and form slots for multiple pins to be inserted. The height of the slots is adapted to the thickness of the pins. The shaping block drive is connected to the two shaping blocks and is adapted to drive the two shaping blocks to move vertically.

[0007] The pin insertion shaping device further includes a pre-insertion positioning component for positioning the connector housing during pin pre-insertion. The pre-insertion positioning component includes: two second positioning blocks that are movably mounted on the frame and can abut against the two sides of the connector housing; and a second positioning block drive unit connected to the two second positioning blocks and adapted to drive the two second positioning blocks to move up and down.

[0008] The pin bending device includes a first support, a bending component, and a bending pressure block assembly. The first support is fixed on the frame and has two opposing bending uprights, each with a mirror-formed arc-shaped bending groove. The bending component is located between the two bending uprights and is driven by a bending drive component. The bending component has a bent portion suitable for bending the pin and sliders located on both sides and slidably connected to the corresponding bending grooves. The bending pressure block assembly includes a bending pressure block and a second pressure block drive component suitable for driving the bending pressure block to move up and down. The bottom surface of the bending pressure block can abut against the unbent portion of the pin, and its side has a blocking surface that abuts against the bent portion of the pin.

[0009] The connector housing feeding device includes a vibratory feeder, a conveying guide rail, a transfer component, and a transfer drive component. The vibratory feeder is adapted to store and convey the connector housing to the vibratory guide rail, and a linear vibrator is provided at the bottom of the vibratory guide rail. The conveying guide rail is located at the discharge end of the vibratory guide rail and below the vibratory guide rail, and is adapted to convey the connector housing. The transfer component is movably installed between the vibratory guide rail and the conveying guide rail, and has a first position corresponding to the vibratory guide rail and a second position corresponding to the conveying guide rail. The transfer component is formed with a mounting groove suitable for preventing the connector housing from falling, and an inlet and an outlet respectively provided at both ends of the mounting groove. In the first position, the inlet corresponds to the discharge end of the vibratory guide rail; in the second position, the outlet corresponds to the inlet of the conveying guide rail. The transfer drive component is fixed on a second support and connected to the transfer component, and is adapted to drive the transfer component to switch between the first position and the second position.

[0010] The connector housing feeding device further includes a fixing rod assembly and an optical fiber sensor. The fixing rod assembly includes a fixing rod fixed to the second support and a limiting block located at the bottom of the fixing rod. The top of the transfer component is formed with a first slot for the limiting block to extend into. The optical fiber sensor is disposed on the fixing rod assembly and is adapted to sense the position of the connector housing on the transfer component and feed the signal back to the control system.

[0011] The conveying guide rail is formed with a second slot located below the connector housing. The connector housing feeding device also includes a plurality of claws and an elastic element. The plurality of claws are rotatably mounted on the claw connecting block. The claws have a first state in which they move in one direction along the second slot and drive the connector housing to move, and a second state in which they move in the opposite direction and separate from the connector housing. The elastic element has one end fixed to the claw connecting block and the other end connected to the claw. The elastic element is adapted to apply an elastic force to the connector housing to maintain it in the first state.

[0012] The pawl has a vertical surface and an inclined surface respectively disposed on both sides of its moving direction. When the pawl is in the first state, the vertical surface abuts against the side of the connector housing; when the pawl is in the second state, the inclined surface slides into contact with the connector housing.

[0013] The needle cutting mechanism is a punch press.

[0014] The technical solution of this invention has the following advantages:

[0015] 1. The fully automatic connector pin cutting and bending equipment provided by the present invention includes a frame, a pin strip reel, a connector housing feeding device, a pin cutting mechanism, a pin transfer robot, a pin insertion and shaping device, and a pin bending device. During production, the pin strip reel feeds the pin strip to the pin cutting mechanism. After the pin cutting mechanism cuts the edges of the pin strip, it is transferred by the pin transfer robot to the pin insertion and shaping device. The pin insertion and shaping device is adapted to insert the pin into the connector housing and shape the pin. Finally, the pin bending device bends the pin. The above equipment realizes the automatic insertion, shaping, and bending of the pin, which greatly improves the production efficiency and ensures the quality of the product.

[0016] 2. The fully automatic connector pin cutting and bending equipment provided by the present invention includes a pin pre-insertion component and a pin insertion shaping component. During assembly, the pin pre-insertion component first inserts a small section of the pin into the connector housing, and then the pin insertion shaping component inserts the pre-inserted pin into place and shapes it. By using the pre-insertion method, the problems of directly inserting the pin into place and having some pins with large inclinations, which make it difficult to shape them later, can be avoided in the prior art, thus ensuring the quality of the pin.

[0017] 3. The fully automatic connector pin cutting and bending device provided by the present invention has a first pressing block with abutting parts corresponding to multiple pins, and a first positioning block disposed on both sides of the multiple abutting parts. The two first positioning blocks abut against the two sides of the connector housing respectively. In this way, after the first pressing block positions the connector housing, the abutting parts push the pins into place, so that there is no need to set up a separate positioning mechanism for the connector housing, and the structure is simpler.

[0018] 4. The fully automatic connector pin cutting and bending equipment provided by the present invention includes a bending component and a bending pressure block assembly. During bending, the bending pressure block abuts against the upper surface of the pin under the drive of the second pressure block drive component. Then, the bending component moves along the arc-shaped bending groove under the drive of the bending drive component, thereby bending the pin. The side of the bending pressure block is provided with a blocking surface that abuts against the bent part of the pin, thereby ensuring the bending angle of the pin.

[0019] 5. The fully automatic connector pin cutting and bending equipment provided by the present invention includes a fixing rod assembly comprising a fixing rod fixed on a second support and a limiting block located at the bottom of the fixing rod. The top of the transfer component is formed with a first slot into which the limiting block extends. Thus, when the connector housing is transferred from the vibrating guide rail to the mounting slot of the transfer component, it is blocked by the limiting block and will not fall out of the outlet.

[0042] The pin cutting mechanism 7 is located on the rear side of the frame 1 and is adapted to receive the cutting pin strip 5 conveyed by the pin strip 2 and cut off the strip edge 4 of the pin strip 5. In this embodiment, since there are a large number of pins assembled with the connector housing 6, the pin cutting mechanism 7 adopts a punch press. It should be noted that when the number of pins is small, a cylinder-driven cutting mechanism can also be used.

[0043] The pin-transfer robot 8 is adapted to transfer the pins 11, after the material strip edge 4 has been cut, to the pin insertion and shaping device 9. In this embodiment, as shown... Figure 2 As shown, the needle insertion and material transfer robot 8 includes a first robot 81, a second robot 82, and a third robot 83. The first robot 81 is located on the rear side of the frame 1 and adjacent to the needle cutting mechanism 7. The first robot 81 is adapted to drive the needle to move left and right along the horizontal direction of the frame 1. The third robot 83 is located on the front side of the frame 1 and is adapted to drive the needle to move left and right along the horizontal direction of the frame 1 to move the needle 11 to the needle insertion and shaping device 9. The second robot 82 is located between the first robot 81 and the third robot 83 and is adapted to drive the needle 11 to move back and forth along the horizontal direction of the frame 1 to transfer the needle 11 from the first robot 81 to the third robot 83.

[0044] A connector housing feeding device 3 is located on the front side of the frame 1, and is positioned to convey the connector housings 6 outwards. Figure 1 , 9 As shown in Figures 10 and 11, the connector housing feeding device 3 includes a vibratory feeder 39, a conveying guide rail 41, a material transfer component 42, a material transfer drive component 45, a fixed rod assembly 47, an optical fiber sensor, multiple claws 52, and an elastic component 54.

[0045] Vibratory feeder 39, suitable for storing and conveying the connector housing 6 to vibratory guide rail 40, the bottom of which is provided with a linear vibrator; Figure 9 and 10 As shown, a conveying guide rail 41 is located at the discharge end of the vibrating guide rail 40 and below it. The conveying guide rail 41 is adapted to convey the connector housing 6. The conveying guide rail 41 has a second slot 51 formed below the connector housing 6. A material transfer member 42 is vertically movable between the vibrating guide rail 40 and the conveying guide rail 41. It has a first position corresponding to the vibrating guide rail 40 and a second position corresponding to the conveying guide rail 41. The material transfer member 42 is formed... The device has a mounting groove suitable for preventing the connector housing 6 from being damaged, and an inlet 43 and an outlet 44 respectively disposed at both ends of the mounting groove. In the first position, the inlet 43 is correspondingly disposed to the outlet end of the vibrating guide rail 40; in the second position, the outlet 44 is correspondingly disposed to the inlet end of the conveying guide rail 41. The material transfer drive 45 is fixed on the second support 46 and connected to the material transfer member 42, and is suitable for driving the material transfer member 42 to switch between the first position and the second position.

[0046] Fixed rod assembly 47, such as Figure 9 As shown, it includes a fixing rod 48 fixed to the second support 46 and a limiting block 49 located at the bottom of the fixing rod 48. The top of the transfer member 42 is formed with a first slot 50 for the limiting block 49 to extend into. The fixing rod assembly 47 is provided with an optical fiber sensor, which is adapted to sense the position of the connector housing 6 on the transfer member 42 and feed the signal back to the control system.

[0047] Multiple claws 52 are rotatably mounted on a claw connecting block 53. Each claw 52 has a first state where it moves in one direction along the second slot 51, driving the connector housing 6 to move, and a second state where it moves in the opposite direction, separating from the connector housing 6. Figure 11As shown, the pawl 52 has a vertical surface 55 and an inclined surface 56 respectively disposed on both sides of its moving direction. When the pawl 52 is in the first state, the vertical surface 55 abuts against the side of the connector housing 6; when the pawl 52 is in the second state, the inclined surface 56 slides into contact with the connector housing 6. One end of the elastic member 54 is fixed to the pawl connecting block 53, and the other end is connected to the pawl 52. The elastic member 54 is adapted to apply an elastic force to the connector housing 6 to maintain it in the first state. It should be noted that the pawl connecting block 53 is provided with a stop (not shown in the figure) for limiting the rotational position of the pawl 52 to keep the pawl 52 in the first state.

[0048] The pin insertion shaping device 9 is adapted to insert the pin 11 into the connector housing 6 and shape the pin 11. The pin insertion shaping device 9 includes a pin pre-insertion assembly 16 and a pin insertion shaping assembly 19.

[0049] Pin pre-insertion assembly 16, such as Figure 3 As shown, it includes a jaw 17 adapted to clamp the pin 11, and a jaw drive 18 adapted to drive the jaw 17 to pre-insert the pin 11 into the connector housing 6.

[0050] The pin insertion shaping assembly 19, located after the pin pre-insertion assembly 16, is adapted to insert the pre-inserted pin 11 into place and shape it. For example... Figure 4 and 5As shown, the pin insertion shaping assembly 19 includes a first pressing block 20, a first pressing block drive 23, two shaping blocks 24, a shaping block drive 26, and a pre-insertion positioning assembly 27. A first pressing block 20 is disposed on the pin insertion side of the connector housing 6. It has abutment portions 21 corresponding to the plurality of pins 11, and first positioning blocks 22 disposed on both sides of the plurality of abutment portions 21. The two first positioning blocks 22 abut against the two sides of the connector housing 6 respectively. A first pressing block drive member 23 is connected to the first pressing block 20 and is adapted to drive the first pressing block 20 to move toward or away from the connector housing 6. Two shaping blocks 24 are disposed on the pin protrusion side of the connector housing 6. The two shaping blocks 24 are arranged vertically and form slots 25 for the plurality of pins 11 to be inserted. The height of the slots 25 is adapted to the thickness of the pins 11. A shaping block drive member 26 is connected to the two shaping blocks 24 and is adapted to drive the two shaping blocks 24 to move vertically. A pre-insertion positioning assembly 27 is adapted to position the connector housing 6 when the pins 11 are pre-inserted. The pre-insertion positioning assembly 27 includes two second positioning blocks 28, which are movably mounted on the frame 1. The two second positioning blocks 28 can abut against the two sides of the connector housing 6. The second positioning block drive member 29 is connected to the two second positioning blocks 28 and is adapted to drive the two second positioning blocks 28 to move up and down.

[0051] The pin bending device 10 is adapted to bend the pin 11. For example... Figure 6-8 As shown, the pin bending device 10 includes: a first support 30, fixed on the frame 1, having two opposing bending uprights 31, the two bending uprights 31 having an arc-shaped bending groove 32 mirror-formed; a bending member 33, disposed between the two bending uprights 31 and driven by a bending drive member 34, the bending member 33 having a bending portion 35 suitable for bending the pin 11, and sliders 36 disposed on both sides and slidably connected to the corresponding bending grooves 32; and a bending pressure block assembly, including a bending pressure block 37, and a second pressure block drive member 38 suitable for driving the bending pressure block 37 to move up and down, the bottom surface of the bending pressure block 37 abutting against the unbent portion of the pin 11, and its side having a blocking surface 57 abutting against the bent portion of the pin 11.

[0052] The working principle of the fully automatic connector pin cutting and bending equipment of the present invention is as follows:

[0053] 1) Feeding of pins 11: The pin strip reel 2 feeds the pin strip to the pin cutting mechanism 7, and then the pin cutting mechanism 7 cuts off the strip edge 4 of the pin strip 5. The first robot arm 81 picks up the multiple pins 11 after cutting and moves horizontally to the right. The second robot arm 82 picks up the pins 11 in the first robot arm 81 and moves horizontally forward. Then the third robot arm 83 transfers the pins 11 to the pin insertion shaping assembly 19.

[0054] Connector housing 6 feeding: Vibratory feeder 39 conveys connector housing 6 to transfer member 42 via vibratory guide rail 40. After the connector housing 6 enters from the feed port of transfer member 42, it is blocked by limit block 49. Then transfer member 42 moves downward, and the vertical surface 55 of claw 52 abuts against connector housing 6, thereby driving connector housing 6 to move out from the discharge port on the right side of transfer member 42 and move to the right to the position to be inserted pin.

[0055] 2) Pin insertion and shaping:

[0056] First, the second positioning block drive 29 of the pre-insertion positioning assembly 27 drives the two second positioning blocks 28 to move downward, thereby positioning the left and right positions of the connector housing 6. Then, the gripper 17 of the pin pre-insertion assembly 16 moves forward under the drive of the gripper drive 18, thereby inserting a portion of the pin 11 into the connector housing 6. Then, the second positioning block drive 29 drives the two second positioning blocks 28 to move upward, and the pawl 52 drives the connector housing 6 to the position to be shaped. Under the action of the first pressure block drive 23, the first pressure block 20 pushes the pin 11 into the slot 25 of the two shaping blocks 24, thereby completing the insertion and shaping.

[0057] 3) Pin bending:

[0058] When the connector housing 6 is moved to the bending position, the bending block 37 of the bending block assembly moves downward under the drive of the second block drive 38, and the bottom surface of the bending block abuts against the pin 11. Then, the bending part 33 moves along the arc-shaped bending groove 32 under the drive of the bending drive 34, and the bending part 35 drives the pin 11 to bend.

[0059] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
