[0054] like Figure 6As shown, the base body 311 is provided with a guide hole 3114 on the side surface away from the offset direction of the material distribution base 31; the material distribution module 30 also includes a limit baffle 33 and a second elastic member 34, wherein the limit baffle 33 is covered at one end of the guide slot 132 away from the offset direction of the material distribution base 31; at least part of the second elastic member 34 extends into the guide hole 3114, and the first end of the second elastic member 34 is connected to the bottom surface of the guide hole 3114, and the second end of the second elastic member 34 is connected to the surface of the limit baffle 33 facing the guide slot 132, so as to provide the material distribution base 31 with an elastic force to move to the first position after the material distribution base 31 is offset. In this way, the reliability of the reset of the material distribution base 31 after the offset is ensured.

[0055] like Figure 1 , Figure 2 , Figure 6 As shown, the material distribution module 30 also includes a third fastener 38 , and the third fastener 38 is used to connect the limit baffle 33 and the storage module 10 .

[0056] like Figure 6 , Figure 8 , Fig.14As shown, the material distribution module 30 includes a material distribution base 31 and two baffle structures 35, the material distribution base 31 includes a base body 311 and a guide slider 312, wherein a material distribution groove 3111 is provided on the base body 311, the material distribution groove 3111 penetrates the first surface of the base body 311 to form a second docking interface, and the material distribution groove 3111 penetrates the second surface of the base body 311 to form a discharge port; the guide slider 312 is arranged on the first surface of the base body 311 and extends in the horizontal direction; two bearing grooves 3115 are also provided on the base body 311, the two bearing grooves 3115 are respectively located on both sides of the length direction of the material distribution groove 3111, and each bearing groove 3115 is connected to the material distribution groove 3111, the first end of each bearing groove 3115 penetrates the first surface of the material distribution base 31, and the second end of each bearing groove 3115 does not penetrate the second surface of the material distribution base 31 surface; the two baffle structures 35 are movably arranged at the two bearing grooves 3115 respectively, and the first supporting bosses 351 are protrudingly arranged on the surfaces of the two baffle structures 35 on the side facing the dividing groove 3111, and each first supporting boss 351 has a limiting step 3511 at the second docking interface; wherein the two baffle structures 35 can move toward and away from each other, and when the two baffle structures 35 move toward each other to the first preset position, the two first supporting bosses 351 move toward each other into the dividing groove 3111, so that the two limiting steps 3511 provide support for the PCI spring piece 12 at the same time; when the two baffle structures 35 move away from each other to the second preset position, the two first supporting bosses 351 move away from each other so that at least two limiting steps 3511 withdraw from the dividing groove 3111, so as to release the support and limiting of the two limiting steps 3511 on the PCI spring piece 12. In this way, by setting the material distribution module 30 to a structural form including a material distribution base 31 and two baffle structures 35, it is ensured that the two limiting steps 3511 on the two baffle structures 35 provide support for the PCI spring piece 12 at the same time, preventing the PCI spring piece 12 from directly sliding out of the discharge port.

[0057] It should be noted that, in the present application, the height of the limiting step 3511 is equal to the thickness of a single PCI spring 12, so that only a single PCI spring 12 falls into the limiting step 3511. In this way, it is ensured that only one PCI spring 12 falls into the limiting step 3511 in a single beat.

[0058] like Figure 4 and Figure 8As shown, the surface of the first supporting boss 351 facing the dividing groove 3111 is a third inclined surface 3512, and in the direction from the second docking interface to the discharge port, the third inclined surface 3512 extends in the direction toward the dividing groove 3111, so that the two third inclined surfaces 3512 limit the PCI spring 12 in the dividing groove 3111. In this way, by setting the third inclined surface 3512 on the surface of the first supporting boss 351 facing the dividing groove 3111, the two relative third inclined surfaces 3512 form a funnel shape that is wide at the top and narrow at the bottom, thereby preventing the PCI spring piece 12 from falling directly from the discharge port after the two limit steps 3511 exit the dividing groove 3111. The space between the two relative third inclined surfaces 3512 becomes narrower as it goes downwards, and has a smaller elastic clamping force to keep the PCI spring piece 12 in the dividing groove 3111, so that the subsequent ejector pin structure 21 can pass through the first pair of interfaces and extend into the dividing groove 3111 through the second pair of interfaces, thereby accurately pushing the PCI spring piece 12 that falls into the dividing groove 3111 from the discharge port to the riveting station.

[0059] like Figure 6 , Figure 8 , Fig. 9 , Fig.14As shown, the baffle structure 35 has a lug structure 352 on the surface facing the material distribution groove 3111, and the lug structure 352 has a mounting hole 3521; the material distribution module 30 also includes a third elastic member 36 and a discharge pin 37, wherein the two ends of the third elastic member 36 are respectively connected to the two mounting holes 3521 to provide a pulling force for the two baffle structures 35 at the same time; the base body 311 also has a receiving groove 3116, and the two ends of the receiving groove 3116 are respectively connected to the two bearing grooves 3115, and the two lug structures 3 52 is slidably arranged at the receiving groove 3116, and the third elastic member 36 is located in the receiving groove 3116; a second supporting boss 353 is also protrudingly arranged on the surface of the baffle structure 35 facing the material distribution groove 3111, and the second supporting boss 353 is spaced apart from the first supporting boss 351, and the end of the second supporting boss 353 facing the discharge port has a fourth inclined surface 3531, and in the direction from the second docking interface to the discharge port, the fourth inclined surface 3531 extends in a direction away from the material distribution groove 3111; the base body 31 1 is also provided with a through hole 3117, which passes through the first surface and the second surface of the base body 311, and the through hole 3117 is connected with the bearing groove 3115, so that the second supporting boss 353 can extend into and out of the through hole 3117, and the hole wall surface of the through hole 3117 is provided with a stop step 3118; the ejector pin 37 is slidably arranged at the through hole 3117, and the ejector pin 37 has a lap step 371 on one side thereof facing the stop step 3118, and the lap step 371 and the stop step 3118 are engaged with each other. The surface of the ejector pin 37 on the side away from the overlapping step 371 has a fifth inclined surface 372 for cooperating with the fourth inclined surface 3531, and the extension direction of the fifth inclined surface 372 is consistent with the extension direction of the fourth inclined surface 3531, so that when the ejector pin 37 slides toward the storage module 10, the fifth inclined surface 372 cooperates with the fourth inclined surface 3531 to push the baffle structure 35 to move in a direction away from the material distribution groove 3111. In this way, the reliability of the two baffle structures 35 moving toward and away from each other is ensured.

[0060] like Fig.12As shown, the pushing mold group 20 includes a first pressing plate 22, a second pressing plate 23, a first fastener 24, a second fastener 25 and a fourth elastic member 26, wherein the first pressing plate 22 has a first assembly hole 221 and a second assembly hole 222; the second pressing plate 23 has a third assembly hole 231 and a fourth assembly hole 232, the third assembly hole 231 is arranged opposite to the first assembly hole 221, and the aperture of the first assembly hole 221 is larger than the aperture of the third assembly hole 231, the fourth assembly hole 232 is arranged opposite to the second assembly hole 222, and the aperture of the second assembly hole 222 is larger than the aperture of the fourth assembly hole 232; the first fastener 24 passes through the first assembly hole 221 and the third assembly hole 231 in sequence to connect the first pressing plate 22 and the second pressing plate 23; wherein the first assembly hole 221 and the third assembly hole 231 are both threadedly connected to the first fastener 24, and the connection between the head and the tail of the first fastener 24 has a first stop ring surface, and the first stop The annular surface is in abutment with the periphery of the third assembly hole 231; a fifth assembly hole 15 is provided at a position of the storage module 10 opposite to the fourth assembly hole 232; the second fastener 25 passes through the second assembly hole 222 and the fourth assembly hole 232 in sequence, and extends into the fifth assembly hole 15 to connect the first pressing plate 22, the second pressing plate 23, and the storage module 10; wherein the second fastener 25 includes a disc section 251, a guide column section 252, and an assembly column section 253 connected in sequence , the outer diameter D1 of the disk segment 251, the outer diameter D2 of the guide column segment 252, and the outer diameter D3 of the assembly column segment 253 satisfy: D1>D2>D3, so that the disk segment 251 overlaps the periphery of the fourth assembly hole 232; the fourth elastic member 26 is sleeved on the outer peripheral side of the guide column segment 252, and the two ends of the fourth elastic member 26 are respectively abutted against the periphery of the disk segment 251 and the fifth assembly hole 15; the assembly column segment 253 is threadedly connected with the fifth assembly hole 15. In this way, by setting the pushing module 20 to include a first pressing plate 22, a second pressing plate 23, a first fastener 24, a second fastener 25 and a fourth elastic member 26, the elastic connection reliability of the pushing module 20 and the storage module 10 is ensured, and the pushing module 20 can accurately push the PCI spring 12 from the discharge port to the riveting station.

[0061] like Fig.12 As shown, the second pressing plate 23 also has a sixth assembly hole 233, and the sixth assembly hole 233 has an annular sink 234; the storage module 10 has a seventh assembly hole 16 at a position opposite to the sixth assembly hole 233; the pushing module 20 also includes a guide column 27, which passes through the sixth assembly hole 233 and the seventh assembly hole 16 in sequence, and the end surface of one side of the head of the guide column 27 overlaps the annular sink 234, and the end surface of the other side of the head of the guide column 27 abuts and cooperates with the surface of the first pressing plate 22 facing the second pressing plate 23. In this way, the setting of the guide column 27 ensures the relative sliding reliability between the pushing module 20 and the storage module 10.

[0062] like Fig.12 As shown, the second pressing plate 23 also has an eighth assembly hole 235; the ejector structure 21 includes an ejector body 211, a weight block 212 and a fifth elastic member 213, wherein the weight block 212 is sleeved on the ejector body 211 and pressed on the topmost PCI spring sheet 12 among the multiple PCI spring sheets 12 to press the multiple PCI spring sheets 12 into a stacked shape; the fifth elastic member 213 is inserted through the eighth assembly hole 235, and the two ends of the fifth elastic member 213 are respectively abutted against one end of the ejector body 211 away from the PCI spring sheet 12 and the surface of the first pressing plate 22 facing the second pressing plate 23, so as to provide the ejector body 211 with an elastic force to push the oblique sliding block 32. In this way, it is ensured that the ejector structure 21 has a certain elasticity during the pushing process, eliminates some gap effects, keeps the pushing process stable, and the weight block 212 presses the multiple PCI spring sheets 12 by gravity and stacks them to maintain a neat arrangement.

[0063] The PCI fixing frame in the present application is a supporting structure of the PCI interface, and the PCI interface is a multi-functional input and output interface.

[0064] It should be noted that, in the present application, the length of the tilting slider 32 is greater than the length of the ejection pin 37 , and the length of the tilting slider 32 passing through the guide hole 313 is greater than the length of the ejection pin 37 passing through the through hole 3117 . In this way, since the length of the inclined slider 32 passing through the guide hole 313 is greater than the length of the discharge ejector pin 37 passing through the through hole 3117, during the overall downward movement of the material distribution module 30, the end of the inclined slider 32 passing through the guide hole 313 preferentially contacts the riveting station. At this time, the end of the inclined slider 32 passing through the guide hole 313 is compressed and retracted by force, while driving the material distribution base 31 to produce a lateral deviation. The lateral deviation of the material distribution base 31 causes the single PCI spring piece 12 located in the material distribution groove 3111 to be misaligned by 0.6 mm from the remaining PCI spring pieces 12 stacked in the storage cavity 11, so that the two positioning holes 121 of the single PCI spring piece 12 are also misaligned. Therefore, no matter how the ejector structure 21 is pushed, it will not directly penetrate into the two positioning holes 121 on the single PCI spring piece 12 in the material distribution groove 3111.

[0065] It should be noted that, in the present application, the length of the inclined sliding block 32 passing through the guide through hole 313 is compressed and retracted just to cause the material distribution base 31 to have a lateral displacement of 0.6 mm.

[0066] It should be noted that, in the present application, just after the material distribution base 31 produces a 0.6mm lateral deviation, the end of the material distribution pin 37 passing through the through hole 3117 immediately contacts the riveting station. At this time, the end of the material distribution pin 37 passing through the through hole 3117 is compressed and retracted, and at the same time, the two baffle structures 35 are pushed to move away from each other and are in an open state, and the length of the open space is just slightly larger than the length of a single PCI spring piece 12 in the material distribution groove 3111. The single PCI spring piece 12 in the material distribution groove 3111 2 is opened, and a third inclined surface 3512 is provided on the surface of the first supporting boss 351 facing the dividing groove 3111, so that the two relative third inclined surfaces 3512 form a funnel shape which is wide at the top and narrow at the bottom, to prevent the PCI spring piece 12 from falling directly from the discharge port after the two limiting steps 3511 exit the dividing groove 3111, and the space between the two relative third inclined surfaces 3512 becomes narrower as it goes downwards, and has a smaller elastic clamping force to keep the PCI spring piece 12 in the dividing groove 3111.

[0067] Furthermore, after the ejector pin 37 has completely retracted, the lower surface of the material distribution base 31 contacts the surface of the station to be riveted and maintains a relative position, the pushing module 20 continues to press down, and the ejector structure 21 passes through the positioning hole 121 on the bottommost PCI spring piece 12 of the remaining PCI spring pieces 12 and continues to press down. Since the single PCI spring piece 12 in the material distribution groove 3111 is misaligned by 0.6mm, the ejector structure 21 directly pushes the single PCI spring piece 12 in the material distribution groove 3111 toward the discharge port, overcomes the clamping force between the two baffle structures 35, and smoothly pushes the single PCI spring piece 12 to the station to be riveted, completing one material distribution.

[0068] It should be noted that, in the present application, since the thickness of a single PCI spring 12 is 0.3 mm, the storage module 10 has four storage cavities 11 , and each storage cavity 11 can store at least 200 PCI springs 12 .
