[0047] Material 2. DETAILED DESCRIPTION

[0048] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0049] like Figure 1-Figure 4 As shown, the clamping and cutting pin insertion device 1 according to an embodiment of the present invention includes: a base 10, a first driving part 11, a second driving part 12, a first matching part 13, a first cam 20, a shearing assembly 30, a second cam 50, a pin insertion assembly 60 and a feeding assembly 80.

[0050] Specifically, the base 10 is fixedly provided with a first driving portion 11, a second driving portion 12 and a first matching member 13; the first cam 20 is transmission-connected to the first driving portion 11; the shearing assembly 30 is transmission-connected to the first cam 20 through the first transmission assembly 40, and the first cam 20 drives the shearing assembly 30 to reciprocate along the first direction; the second cam 50 is transmission-connected to the first driving portion 11; the pin assembly 60 is movably provided on the base 10, and the pin assembly 60 is transmission-connected to the second cam 50 through the second transmission assembly 70 to reciprocate along the second direction, and the pin assembly 60 is movably connected to the second transmission assembly 70, and the pin assembly 60 is fixedly provided with a first Two mating parts 61, the second mating part 61 is transmission-connected with the first mating part 13 to drive the pin assembly 60 to move back and forth in the first direction while moving back and forth in the second direction; the feeding assembly 80 is transmission-connected with the second driving part 12, and the feeding assembly 80 is used to drive the material 2 to move toward the direction close to the shearing assembly 30, wherein the shearing assembly 30 has a shearing position. When the shearing assembly 30 moves to the shearing position, the shearing assembly 30 can cut and clamp the material 2. The pin assembly 60 has a pin position. When the pin assembly 60 moves to the pin position, the pin 62 fixed on the pin assembly 60 can be inserted into the material 2, and the first direction and the second direction are perpendicular.

[0051] Specifically, the shearing assembly 30 has a first position and a shearing position. The first cam 20 drives the shearing assembly 30 to reciprocate between the first position and the shearing position. The line connecting the first position and the shearing position is along the first direction. After the shearing assembly 30 moves from the first position to the shearing position and shears the material 2, it moves back to the first position to make way for continued conveying of the material 2. The pin assembly 60 has a second position and a pin position. The displacement between the second position and the pin position has displacement components in both the second and first directions. That is, the second cam 50 drives the pin assembly 60 to move in the second direction, causing the pin assembly 60 to generate a displacement component in the second direction. During the movement of the pin assembly 60 in the second direction, the transmission connection between the second mating member 61 and the first mating member 13 causes the pin assembly 60 to generate a displacement component in the first direction. That is, the actual displacement of the pin assembly 60 is the superposition of the displacement component in the second direction and the displacement component in the first direction.

[0052] The feeding assembly 80 is used to drive the material 2 to move toward the direction close to the shearing assembly 30. More specifically, the feeding assembly 80 is used to drive the material 2 to move toward the direction gradually approaching the shearing position so that the shearing assembly 30 can shear and clamp the material 2 when it moves to the shearing position. When the pin assembly 60 moves from the second position to the pin position, since the feeding assembly 80 keeps driving the material 2 to move, the pin assembly 60 cannot accurately insert the pin 62 into the material 2 when the material 2 moves. Therefore, the transmission of the first mating piece 13 and the second mating piece 61 is set. After the shearing assembly 30 cuts and clamps the material 2, the pin 62 fixed on the pin assembly 60 is gradually inserted into the shortened material 2 until the pin 62 is installed in place and the pin assembly 60 moves to the pin position. The shearing assembly 30 and the pin assembly 60 relatively clamp the cut material 2 together. After that, the pin assembly 60 is peeled off from the pin 62. After that, the shearing assembly 30 releases the material 2, and the shearing assembly 30 moves toward the first position, and the pin assembly 60 moves toward the second position. The material 2 assembled with the pin moves to the next workstation.

[0053] It should be noted that the shearing assembly 30 can not only cut the material 2, but also can punch the material 2 when the shearing assembly 30 moves to the shearing position by setting the shape of the blade of the shearing assembly 30, thereby obtaining a product of corresponding shape.

[0054] Secondly, the first driving unit 11 and the second driving unit 12 both include motors.

[0055] According to the clamping and pin insertion device 1 of the embodiment of the present invention, the first driving part 11 can drive the shearing component 30 and the pin insertion component 60 to realize separate movements, and at the same time can realize controlling the time interval of the movement of the shearing component 30 and the pin insertion component 60. Through the transmission of the second cam 50 and the first matching part 13 and the second matching part 61, after the shearing component 30 cuts the material 2 and keeps the material 2 stationary, the pin insertion component 60 can start to move to insert the pin 62 into the material 2, shortening the time interval between the two processes, thereby ensuring that the shearing and pin insertion processes of the clamping and pin insertion device 1 are of the same frequency and rhythm, which can greatly reduce the scrap rate and improve the processing efficiency of finished products.

[0056] According to the embodiment of the present invention, the clamping and cutting pin device 1, as shown in FIG. Figure 5 、 Figure 12 as well as Figure 14 As shown, the outer circumferential surface of the first cam 20 is provided with a boss 21 extending along its circumferential direction. The first transmission assembly 40 includes a first transmission member 41, one end of which is provided with at least one limiting wheel 42, which abuts against one side of the boss 21. In this embodiment, two opposing limiting wheels 42 are provided at one end of the transmission member 41, and the two limiting wheels 42 are rotatably abutted against two sides of the boss 21. The first cam 20 rotates about a fixed axis, and the rotation axis of the first cam 20 extends along the first direction. By providing the two side profiles of the boss 21, different positions of the two side profiles of the boss 21 contact the limiting wheels 42 during the rotation of the first cam 20. Therefore, the change in the two side profiles of the boss 21 guides the limiting wheel 42 to generate displacement in the first direction, thereby driving the first transmission member 41 to generate displacement in the first direction through the limiting wheel 42, and then driving the shearing assembly 30 to generate displacement in the first direction through the first transmission member 41. By providing two opposite limiting wheels 42 respectively against the two sides of the boss 21 , the first transmission member 41 can be prevented from being disengaged from the first cam 20 , thereby ensuring the operational stability of the pin-cutting device 1 .

[0057] In some embodiments, as Figure 14As shown, the first cam 20 includes a first end and a second end opposite each other along the thickness direction, and the boss 21 includes a first sub-boss segment 212, a second sub-boss segment 214, and a transition segment 216. The distance between the centerline of the first sub-boss segment 212 along its extension direction and the first end is smaller than the distance between the centerline of the first sub-boss segment 212 along its extension direction and the second sub-boss segment 214 along its extension direction. The distance between the centerline of the second sub-boss segment 214 along its extension direction and the first end is larger than the distance between the centerline of the second sub-boss segment 214 along its extension direction and the second end. The leading and trailing ends of the first sub-boss segment 212 in the extension direction are transitionally connected to the leading and trailing ends of the second sub-boss segment 214 in the extension direction via the transition segment 216. This configuration can simplify the profile setting of the boss 21 and reduce the difficulty of processing.

[0058] For the sake of convenience of explanation, the first end is defined as the end away from the shearing position, and the second end is defined as the end close to the shearing position. When the two limiting wheels 42 are against both sides of the first sub-boss segment 212, the shearing assembly 30 is located in the first position. When the two limiting wheels 42 are against the transition segment 216, the shearing assembly 30 moves from the first position to the shearing position. When the two limiting wheels 42 are against both sides of the second sub-boss segment 214, the shearing assembly 30 is in the shearing position. By setting the length of the second sub-boss segment 214 and combining the rotation speed of the first cam 20, the time the shearing assembly 30 stays at the shearing position can be controlled, thereby providing operating time for the needle assembly 60 to insert the needle into the cut material 2.

[0059] Among them, preferably, the cross-sectional areas of the first sub-boss segment 212 at various locations between the head and tail ends along its extension direction are equal, and the cross-sectional areas of the second sub-boss segment 214 at various locations between the head and tail ends along its extension direction are equal. The head and tail ends of the first sub-boss segment 212 in the extension direction are respectively smoothly connected to the head and tail ends of the second sub-boss segment 214 in the extension direction through the transition section 216, so that the movement of the shearing assembly 30 can be smoother.

[0060] In some embodiments, as Figure 9 and Figure 11As shown, the shearing assembly 30 includes a first guide groove 31. A sliding wheel 43 is provided at the other end of the first transmission member 41. The sliding wheel 43 is slidably engaged in the first guide groove 31, and the first guide groove 31 extends in the second direction. This is because during the rotation of the first cam 20, the limiting wheel 42 is driven by the first cam 20 to produce a small displacement in the second direction when the friction between the limiting wheel 42 and the first cam 20 is not overcome. By providing the sliding wheel 43 of the first transmission member 41 and the first guide groove 31 of the shearing assembly 30, when the first transmission member 41 moves in the second direction away from the shearing assembly 30, the sliding wheel 43 slides in the first guide groove 31 without synchronously driving the shearing assembly 30 in the second direction. This ensures the operational stability of the pin-cutting and inserting device 1 and prevents transmission jams of the first transmission member 41 and the shearing assembly 30.

[0061] According to the embodiment of the present invention, the clamping and cutting pin device 1, as shown in FIG. Figure 3 and Figure 5 As shown, it also includes a first bracket 16, which defines a second guide groove 162 along the third direction. The first bracket 16 is arranged between the first cam 20 and the shearing assembly 30, and the first transmission member 41 can be movably clamped in the second guide groove 162, so that the first transmission member 41 can be limited and guided to ensure that the first transmission member 41 can move within a preset range of movement, and at the same time support the first transmission member 41, so that the first transmission member 41 can be movably connected with the shearing assembly 30 through the cooperation of the sliding wheel 43 and the first guide groove 31.

[0062] The first direction, the second direction and the third direction are perpendicular to each other.

[0063] In some embodiments, as Figure 5 、 Figure 9 and Figure 10 As shown, a limiting post 164 is further provided in the second guide groove 162. A limiting hole 412 is provided on the first transmission member 41. The limiting post 164 is inserted into the limiting hole 412. The limiting post 164 and the limiting hole 412 are clearance-matched, so that the limiting hole 412 can move relative to the limiting post 164 in the first direction. This can better ensure the reliability of the movement of the first transmission member 41 and prevent the first transmission member 41 from moving outside the predetermined range of movement. The limiting post 164 and the limiting hole 412 are clearance-matched, so that the inner diameter of the limiting hole 412 can provide space for the limiting post 164 to move in the first direction.

[0064] According to the embodiment of the present invention, the clamping and cutting pin device 1, as shown in FIG. Figure 12 and Figure 15As shown, a cam groove 51 is provided on the end face of the second cam 50, and the second transmission assembly 70 includes a first follower part 71, and a first guide wheel 72 is provided at one end of the first follower part 71. The first guide wheel 72 can be movably clamped in the cam groove 51, and the other end of the first follower part 71 is transmission-connected to the pin assembly 60.

[0065] Among them, the second cam 50 rotates around a fixed axis, and the rotation axis of the second cam 50 extends along the first direction. When the second cam 50 rotates, the cam groove 51 rotates at the same time, and the cam groove 51 guides the first guide wheel 72 to drive the first follower 71 to move according to a predetermined motion trajectory. As the second cam 50 continues to rotate, the first follower 71 can move back and forth along the second direction.

[0066] In some embodiments, as Figure 1 、 Figure 12 、 Figure 13 as well as Figure 17 As shown, the second transmission assembly 70 also includes a second follower 73, one end of the second follower 73 is fixedly connected to the other end of the first follower 71, and the other end of the second follower 73 is transmission-connected to the pin assembly 60. A third guide groove 14 is provided on the base 10, and the second follower 73 can be movably clamped in the third guide groove 14. The third guide groove 14 extends along the second direction, so that the third guide groove 14 plays a guiding role for the second follower 73, driving the second follower 73 to move according to a predetermined motion trajectory. As the second cam 50 rotates continuously, the second follower 73 moves back and forth along the third guide groove 14.

[0067] A third guide rail is provided on the base 10 , and the third guide rail defines a third guide groove 14 .

[0068] In some embodiments, as Figure 12 and Figure 13 As shown, the second transmission assembly 70 further includes a sliding block 74, which is fixed to the second follower portion 73. The pin assembly 60 defines a fourth guide slot 63, in which the sliding block 74 is engaged. The sliding block 74 and the pin assembly 60 are movable relative to each other. Specifically, the first follower portion 71 moves in the second direction, driving the second follower portion 73 and the sliding block 74 to move in the second direction. The transmission cooperation between the first mating member 13 and the second mating member 61 causes the sliding block 74 to move in the second direction while the pin assembly 60 drives the fourth guide slot 63 to move along the sliding block 74 in the first direction. The pin assembly 60 generates displacement components in both the first and second directions, thereby enabling the first driving portion 11 to simultaneously drive the first cam 20 and the second cam 50 to rotate, thereby driving the shearing assembly 30 and the pin assembly 60 to move. This also enables the time interval between the movements of the shearing assembly 30 and the pin assembly 60 to be controlled.

[0069] According to the embodiment of the present invention, the clamping and cutting pin device 1, as shown in FIG. Figure 12 、 Figure 13 and Figure 16 As shown, the second mating part 61 includes a guide surface 612, and the first mating part 13 includes a limiting wheel 42 and a limiting column 164. The limiting wheel 42 is rotatably fixed to the base 10 through the limiting column 164. The limiting wheel 42 and the second mating part 61 are movably connected so that the limiting wheel 42 always rests on the guide surface 612, and the angle between the tangent of the guide surface 612 at any point along its extension direction and any straight line extending along the second direction is not 0.

[0070] In some embodiments, the first mating piece 13 and the second mating piece 61 are arranged on the side of the fourth guide groove 63 away from the shearing assembly 30, and the guide surface 612 is inclined in a direction gradually away from the fourth guide groove 63 from the second cam 50 to the pin assembly 60.

[0071] According to the clamping and inserting pin device 1 according to the embodiment of the present invention, the limiting wheel 42 and the first matching piece 13 are movably assembled through a limiting mechanism, so that the limiting wheel 42 always abuts against the guide surface 612, thereby guiding the limiting wheel 42 to produce displacement along the first direction by setting the angle between the guide surface 612 and any straight line extending along the second direction. For example, a limiting groove is provided on the first matching piece 13, and a guide slider is further provided on the second matching piece 61. The guide slider is provided below the limiting wheel 42 and spaced from the limiting wheel 42. The guide slider is movably clamped in the limiting groove to prevent the guide slider from escaping the limiting groove, thereby preventing the limiting wheel 42 from detaching from the guide surface 612, so that the limiting wheel 42 always abuts against the guide surface 612.

[0072] According to the embodiment of the present invention, the clamping and cutting pin device 1, as shown in FIG. Figure 3 、 Figure 4 、 Figure 18 and Figure 19 As shown, the feeding assembly 80 includes a feeding track 81 and a feeding wheel 82. The feeding track 81 is used to transport the material 2, and the feeding track 81 extends along the third direction; the second driving part 12 is connected to the feeding wheel 82 in a transmission manner, and the outer circumferential surface of the feeding wheel 82 is provided with a plurality of evenly distributed positioning protrusions 822. The feeding wheel 82 is arranged relative to the feeding track 81 so that the positioning protrusions 822 are inserted into the pin 62 holes of the material 2 to drive the material 2 to move.

[0073] According to the clamping and pin-insertion device 1 of the embodiment of the present invention, by setting the feeding track 81, the material 2 can be moved along a predetermined trajectory to prevent the material 2 from deviating during transportation. By setting the positioning protrusion 822 to be inserted into the pin 62 hole of the material 2 to drive the movement of the material 2, the material 2 can be accurately transmitted, so that it can cooperate with the shearing component 30, so that the material 2 cut by the shearing component 30 can meet the design specifications.

[0074] Among them, the first direction, the second direction and the third direction are used to define the coordinate system. For example, when the first direction is the left-right direction, the second direction can be the front-back direction, and the third direction can be the up-down direction. Usually at this time, the feeding direction is from top to bottom, which makes it convenient for the connector with completed pin insertion to be transported to the next process.

[0075] In some embodiments, a second bracket is further provided on the base 10 , and the feeding track 81 , the feeding wheel 82 and the second driving unit 12 are all installed on the second bracket.

[0076] In some embodiments, as Figure 3 and Figure 4 As shown, the feeding assembly 80 also includes a feeding handle 83 and a stop member. The stop member is movably arranged in the feeding track 81. The feeding handle 83 is transmission-connected to the stop member. The rotation of the feeding handle 83 can drive the stop member to move toward or away from the bottom wall of the feeding track 81. The feeding handle 83 has a locking position and an unlocking position. The feeding handle 83 is rotatable between the locking position and the unlocking position. When the feeding handle 83 is rotated from the unlocking position toward the locking position, the stopper moves in a direction gradually approaching the bottom wall of the feeding track 81 until the feeding handle 83 is in the locking position. The stopper and the bottom wall of the feeding track 81 clamp the material 2, and the material 2 cannot move. When the feeding handle 83 moves from the locking position to the unlocking position, the stopper moves in a direction gradually away from the bottom wall of the feeding track 81 until the feeding handle 83 is in the unlocking position. The distance between the stopper and the bottom wall of the feeding track 81 is sufficient for the material 2 to pass through, so that when the clamping and cutting needle insertion device 1 is in a shutdown state or a paused state, the feeding handle 83 is used to control the material 2 to stop moving.

[0077] In some embodiments, as Figure 6 and Figure 8 As shown, a fixed knife portion 84 is provided at the outlet end of the feeding track 81 , and the shearing assembly 30 and the fixed knife portion 84 cooperate to shear the material 2 , which makes it easier to cut the material 2 and simplifies the structural setting of the shearing assembly 30 .

[0078] According to the clamping and cutting pin insertion device 1 of an embodiment of the present invention, a clearance hole extending along the first direction is provided on the end face of the shearing component 30 facing the material 2. When the pin insertion component 60 is in the pin insertion position, the pin 62 is passed through the clearance hole, so that the clearance hole can better ensure that the pin 62 is inserted perpendicular to the material 2. At the same time, the clearance hole can provide an accommodation space for the pin 62 when the shearing component 30 clamps the shortened material 2.

[0079] In some embodiments, the shearing assembly 30 includes a clamping portion and a pushing portion. After the pin 62 is installed, the clamping portion releases the material 2, and the pushing portion pushes the material 2 so that the pin 62 is disengaged from the clearance hole, thereby separating the shearing assembly 30 from the material 2 with the pin inserted.

[0080] According to the embodiment of the present invention, the clamping and cutting pin device 1, as shown in FIG. Figure 1 and Figure 3 As shown, the first cam 20 and the second cam 50 are both mounted on the transmission shaft 15, and the transmission shaft 15 is connected to the first driving part 11 through a belt drive. In this way, the first driving part 11 can smoothly drive the transmission shaft 15 to rotate, and the rotation of the transmission shaft 15 drives the first cam 20 and the second cam 50 to rotate synchronously, thereby achieving smooth transmission. The belt drive also has the advantages of simple structure, no need for lubrication, easy maintenance, and the ability to transmit power between large wheelbases.

[0081] In some embodiments, a first gear 112 is sleeved on the output shaft of the first driving part 11 , a second gear 152 is sleeved on the transmission shaft 15 close to the first driving part 11 , and a transmission belt 154 is sleeved outside the first gear 112 and the second gear 152 .

[0082] The pin-cutting device 1 according to an embodiment of the present invention further includes a base 90. The base 10 is movably disposed on the base 90. A sliding guide rail 91 is provided on one of the base 90 and the base 10, and a sliding groove is provided on the other. The sliding guide rail 91 is embedded in the sliding groove. The sliding guide rail 91 and the sliding groove can move relative to each other, so that the movement of the base 10 drives all components on the base 10 to move, so that after the pin-cutting device 1 is placed in place, the distance between it and other process equipment can still be fine-tuned.

[0083] That is, in some embodiments, Figure 5 、 Figure 6 as well as Figure 20 As shown, a sliding guide rail 91 is provided on the base 90 , and a sliding portion 17 is provided on the base 10 . The sliding portion 17 defines a sliding groove. In some embodiments, a sliding groove is provided on the base 90 , and a sliding guide rail 91 is provided on the base 10 .

[0084] In some embodiments, as Figure 6 and Figure 7 As shown, the clamping and cutting pin insertion device 1 also includes a locking handle 18 and a locking member 19. The locking handle 18 is transmission-connected to the locking member 19. A locking hole passing through the base 10 in the thickness direction is provided. The locking member 19 is passed through the locking hole. The locking handle 18 is movable between a third position and a fourth position. When the locking handle 18 is in the third position, the locking member 19 is spaced apart from the base 90. When the locking handle 18 is in the fourth position, the locking member 19 is against the base 90.

[0085] When the distance between the base 10 and other processes needs to be adjusted, the locking handle 18 is rotated from the fourth position toward the third position so that the base 10 can move relative to the base 10. After the base 10 moves into place, the locking handle 18 is rotated from the third position to the fourth position to lock the base 10 and the base 90. Therefore, through the cooperation of the locking handle 18 and the locking member 19, the base 10 is fixed to the base 90 when the base 10 is working, preventing the base 10 from moving relative to the base 90 due to accidental contact or misconception.
