The connecting rod clamp is used to realize the transportation of the connecting rod 10 between the container box and the positioning block 7, and the positioning block clamp is used to realize the transportation of the positioning block 7 in the operating platform 6;

[0045] The second transfer robot 2 is located between the operating platform 6 and the injection molding machine 9, and is used to transport the positioning block 7 between the operating platform 6 and the injection molding chamber.

[0046] The connecting rod 10 in the container box of the present application is positioned by the positioning assembly, the positioning block clamp opens the positioning block 7, the connecting rod clamp places the connecting rod 10 in the connecting rod loading and positioning module 3 into the positioning block 7, and the second transfer robot 2 places the positioning block 7 containing the connecting rod 10 into the injection molding chamber for injection molding, so that the connecting rod 10 forms a transmission rod after injection molding; the second transfer robot 2 places the positioning block 7 containing the transmission rod back to the operating platform 6, the positioning block clamp opens the positioning block 7, and the connecting rod clamp takes out the transmission rod in the positioning block 7 at the same time.

[0047] The present application adopts a positioning block clamp to realize the opening and closing of the positioning block 7, and cooperates with the connecting rod clamp to realize the removal and placement of the connecting rod 10 and the transmission rod from the positioning block 7, and adopts the second transmission robot 2 to realize the transportation of the positioning block 7 between the operating platform 6 and the injection molding chamber. When the positioning block 7 moves from the operating platform 6 to the injection molding chamber, the connecting rod 10 is inside it.

The left container box 11 and the right container box 12 have the same structure and are symmetrically distributed. Loading on both sides can realize the loading of two connecting rods 10 at a time, thereby improving the loading efficiency.

[0050] The present application sets the horizontal cross-sectional area of ​​the top of the blocking plate 13 to be smaller than the horizontal cross-sectional area of ​​the bottom; the distance between the bottom end of the blocking plate 13 and the left loading plate 14 and the right loading plate 15 is smaller than the outer diameter of the connecting rod 10; the distance between the top of the blocking plate 13 and the left loading plate 14 and the right loading plate 15 is larger than the outer diameter of the connecting rod 10.

The first trapezoidal positioning component 16 and the elastic push plate 20 cooperate with each other to realize the positioning of the connecting rod 10. The first trapezoidal positioning component 16 abuts against the connecting rods 10 in the left loading plate 14 and the right loading plate 15, and the contact surfaces of the first trapezoidal positioning component 16 and the two connecting rods 10 are located in different vertical planes, and the distance between the two contact surfaces is related to the positions of the two connecting rods 10 in the positioning block 7.

The sixth pneumatic finger 53 is arranged at the lower end of the sixth connecting plate 52. The sixth pneumatic finger 53 includes symmetrically arranged perforated clamps 54. The sixth clamp 48 is used to place the positioning block 7 of the transmission rod from the injection molding chamber to the second station. When the sixth pneumatic finger 53 is running, the two perforated clamps 54 move toward or away from each other, so that the positioning block 7 is clamped or released.

[0063] In order to improve the material unloading efficiency of the transmission rod, the present application also includes a material receiving module 8 on the side of the operating platform 6, as shown in the attached Figure 7As shown, the receiving module 8 includes a transmission line 70 and a recycling box 71. The recycling box 71 is located below the end of the transmission line 70. The transmission line 70 is used to place the transmission rod. The third fixture 23 places the transmission rod in the positioning block 7 on the transmission line 70. The transmission rod falls into the recycling box 71 under the drive of the transmission line 70, realizing automatic unloading of the transmission rod.

[0064] The automatic assembly method of the transmission rod of the present application is specifically as follows:

[0065] The connecting rod 10 is manually placed in the left container box 11 and the right container box 12. When the detection component 17 detects that there is no product at the first trapezoidal positioning component 16, the left loading plate 14 and the right loading plate 15 descend to the bottom and then move upward. During the upward movement, the holding grooves on the top of the left loading plate 14 and the right loading plate 15 lift the connecting rod 10. The left loading plate 14 and the right loading plate 15 move upward close to the blocking plate 13. At this time, it is easy to lift two connecting rods 10 at a time. Since the upper part of the blocking plate 13 is narrower than the bottom, when the two connecting rods 10 lifted by the left loading plate 14 and the right loading plate 15 rise above the blocking plate 13, one of the connecting rods 10 falls off, ensuring that only one connecting rod 10 is lifted. When the left loading plate 14 and the right loading plate 15 move upward to the positioning position, one side of the two connecting rods 10 is the first trapezoidal positioning component 16, and the two elastic push plates 20 push the two connecting rods 10 at the same time under the action of the first cylinder 19, so as to achieve the simultaneous and precise positioning of the two connecting rods 10. When the detection component 17 detects that there is a connecting rod 10 at the first trapezoidal positioning component 16, it transmits a signal that the connecting rod 10 is positioned in place to the first transmission robot 1.

[0066] After receiving the signal that the connecting rod 10 is positioned in place, the first transfer robot 1 drives the fourth clamp 24 to the connecting rod 10. The fourth pneumatic fingers 41 in the fourth left component 38 and the fourth right component 39 operate simultaneously, the fourth left groove clamping plate 42 and the fourth right groove clamping plate 44 operate toward the fourth middle clamping plate 43, the fourth left component 38 and the fourth right component 39 clamp the connecting rod 10 simultaneously, realizing the function of automatically taking the connecting rod 10, and the first transfer robot 1 drives the fourth clamp 24 to operate to the starting position.

[0067] After the first transfer robot 1 receives the signal that the positioning block 7 on the second station is in place, it drives the first clamp 21 to run to the second station, and the first pneumatic finger 26 runs, and the E-type clamp 27 clamps the positioning block cover 64. The mushroom heads on both sides of the E-type clamp 27 clamp the four clamping holes 66 of the positioning block cover 64, and the middle boss of the E-type clamp 27 clamps the upper edges of the two spring clips 67 of the positioning block cover 64. The spring clips 67 pop out from the slots 68 of the positioning block base 65, and the first transfer robot 1 runs upward to remove the positioning block cover 64, thereby realizing the function of the first transfer robot 1 automatically opening the positioning block 7.

[0068] The first transfer robot 1 drives the third fixture 23 to rotate above the positioning block 7 in the second station. The third pneumatic fingers 34 in the third left component 31 and the third right component 32 in the third fixture 23 operate simultaneously, the third left groove clamping plate 35 and the third right groove clamping plate 37 operate toward the direction of the third middle clamping plate 36, and the third left component 31 and the third right component 32 clamp the transmission rod simultaneously, so that the first transfer robot 1 automatically takes the transmission rod.

At this time, the first positioning cylinder 57 and the second positioning cylinder 58 in the first station operate to achieve accurate positioning of the positioning block base 65.

[0070] The first transmission robot 1 drives the fourth fixture 24 to rotate to the position of the positioning block base 65 in the first station. At this time, the fourth fixture 24 has clamped the connecting rod 10. The fourth fixture 24 drives the connecting rod 10 to run, the fourth pneumatic finger 41 runs, the fourth left groove clamping plate 42 and the fourth right groove clamping plate 44 run in the opposite direction of the fourth middle clamping plate 43, the fourth left component 38 and the fourth right component 39 release the connecting rod 10 at the same time, and the connecting rod 10 is placed in the two slots 68 of the positioning block base 65. The second cylinder 45 in the fourth fixture 24 drives the second pressing plate 46 downward and runs in the direction of the second trapezoidal positioning component 61. The second pressing plate 46 and the second trapezoidal component cooperate with each other to realize the precise positioning of the connecting rod 10, and finally realize the function of automatically placing the connecting rod 10; and in the process of positioning, clamping and placing the connecting rod 10, the shape of the first trapezoidal positioning component 16 and the shape of the second trapezoidal positioning component 61 are the same, ensuring that the staggered distance of the two connecting rods 10 is always consistent.

[0071] The first transfer robot 1 drives the first fixture 21 to rotate to the position of the positioning block base 65 in the first workstation. At this time, the first fixture 21 clamps the positioning block cover 64, the first pneumatic finger 26 in the first fixture 21 runs, the E-type clamp 27 is released, and the two spring clips 67 of the positioning block cover 64 are inserted into the two slots 68 of the positioning block base 65, thereby realizing the function of automatically locking the positioning block 7.

[0072] The first transfer robot 1 drives the second clamp 22 to rotate to the position of the positioning block 7 in the first workstation, and the second pneumatic finger 29 runs. The boss clamp 30 in the second pneumatic finger 29 presses the lower edge of the two spring clips 67 of the positioning block cover 64, ensuring that the two spring clips 67 can be tightly locked in the two slots 68 of the positioning block base 65, further ensuring that the positioning block 7 is automatically buckled into place.

[0073] The first transfer robot 1 drives the third clamp 23 to transfer to the transmission line 70 of the material receiving module 8. At this time, the third clamp 23 clamps the transmission rod; the third clamp 23 runs, and the third pneumatic fingers 34 in the third left component 31 and the third right component 32 run at the same time, and the third left groove clamp 35 and the third right groove clamp 37 run in the opposite direction of the third middle clamp 36, and the third left component 31 and the third right component 32 release the transmission rod at the same time, realizing the function of the first transfer robot 1 automatically placing the transmission rod to the material receiving module 8.

[0074] When the second transfer robot 2 receives the signal that the positioning block 7 with the connecting rod 10 is positioned in place, it drives the fifth fixture 47 to run to the first station, the fifth pneumatic finger 50 in the fifth fixture 47 runs, the two mushroom head clamps 51 run inward, and the four mushroom heads on both sides of the two mushroom head clamps 51 are clamped into the four clamping holes 66 of the positioning block 7, and the second transfer robot 2 drives the positioning block 7 on the first station to move to the injection molding chamber to realize the function of automatically clamping the positioning block 7 with the connecting rod 10. When the second transfer robot 2 drives the fifth fixture 47 to run to the injection molding chamber, the fifth pneumatic finger 50 runs, the two mushroom head clamps 51 run in the opposite direction, and the positioning block 7 with the connecting rod 10 is released, realizing the function of automatically placing the positioning block 7 with the connecting rod 10 into the mold cavity.

[0075] When the second transfer robot 2 receives the signal that the injection molding chamber has completed production, the second transfer robot 2 drives the sixth clamp 48 to operate in the injection molding chamber, the sixth pneumatic finger 53 in the sixth clamp 48 operates, and the two perforated clamps 54 clamp the positioning block 7 in the injection molding chamber and move it to the second station. When the second transfer robot 2 drives the positioning block 7 to move to the second station, the pneumatic finger in the sixth clamp 48 operates, and the two perforated clamps 54 loosen the positioning block 7 with the transmission rod. At the same time, the third positioning cylinder 59 and the fourth positioning cylinder operate to clamp the positioning block 7 with the transmission rod, thereby automatically placing the positioning block 7 with the transmission rod. All equipment starts the next cycle.
