The second transfer guide plate is in the shape of an arc plate, and one side of the second transfer guide plate is fixedly connected to the other side of the third transfer protective shell, so that the valve core transfer wheel 44 can transfer the valve core 2 to the valve core clamping positioning member. The third transfer protective shell and the fourth transfer protective shell can prevent the valve core 2 from escaping from the valve core transfer groove 43 during the process of the valve core transfer wheel 44 transferring the valve core 2.

[0073] It should be noted that the rotational power of the fourth transmission shaft 41 is driven by the valve core clamping positioning member or an additional motor as needed. The rotation speed of the fourth transmission shaft 41 is the same as the rotation speed of the first valve core clamping positioning member, and the rotation direction is opposite.

[0078] The second valve core clamping and positioning member has the same structure as the first valve core clamping and positioning member. The second valve core clamping and positioning member is distributed parallel and symmetrically with the first valve core clamping and positioning member on the second bracket 18 and the fourth bracket 52 on the workbench 5, and the valve core clamping drive belt 46 of the second valve core clamping and positioning member corresponds to and fits with the valve core clamping drive belt 46 of the first valve core clamping and positioning member, so that the valve core positioning groove 51 of the second valve core clamping and positioning member and the valve core positioning groove 51 of the first valve core clamping and positioning member simultaneously clamp and position one of the valve cores 2, so that the valve core 2 is circumferentially constrained to be positioned in the two valve core positioning grooves 51 (the valve core can move axially in the two valve core positioning grooves 51), so that the axis of the valve core 2 coincides with the axis of the spring 1, so that the valve core 2 is automatically inserted into the inner ring of the spring 1. It should be noted that the fourth bracket 52 is plate-shaped, and the distance between the fourth bracket 52 and the second bracket 18 is greater than the distance between the third bracket 19 and the second bracket 18, so as to facilitate the installation of the valve core assembly on the second valve core clamping positioning member.

[0079] The synchronous transmission member includes a fifth worm 53 and a fifth worm wheel 54. The fifth worm 53 is fixedly sleeved on the transmission rod 31, and the fifth worm wheel 54 is fixedly sleeved on one end of the fifth transmission shaft 47, and the fifth worm wheel 54 is meshed with the fifth worm 53.

When the fifth worm 53 rotates, it can drive the two fifth worm wheels 54 to rotate in opposite directions at the same speed at the same time. And the valve core clamping positioning member and the spring clamping positioning member have the same rotation speed, which further improves the positioning accuracy of the valve core 2 and the spring, and improves the assembly efficiency and accuracy of the injector valve core.

[0080] The valve core assembly includes a valve core assembly transmission part and a valve core pusher 58.

The first magnetic coil is fixedly embedded in the spiral groove on the inner wall of the valve core push seat, and the valve core push shaft is axially slidably embedded in the valve core push seat tube. When a positive direct current is passed through the first magnetic coil to generate a magnetic field, the valve core push shaft will be pushed forward to insert the free end of the cylindrical portion 4 of the valve core 2 in synchronous movement into the spring 1; after the insertion, when a reverse direct current is passed through the first magnetic coil to generate a magnetic field, the valve core push shaft will be pulled backward to retract into the valve core push seat. Furthermore, the valve core push members 58 are provided in plurality, and the plurality of valve core push members 58 are evenly spaced on the assembly drive belt 57, so that the plurality of valve core push members 58 correspond to the plurality of valve core positioning grooves 51 one by one. It should be noted that due to the existence of the second positioning ring, the cylindrical body 4 of the valve core 2 cannot be fully inserted into the spring 1, and the valve core 2 detection and transport member is required to further clamp the valve core 2 and the spring 1 in the axial direction to complete the assembly of the injector valve core. As an option, the valve core push member 58 can also be a miniature automatic telescopic rod to automatically extend into the valve core positioning groove 51 to push the valve core into the spring 1.

[0082] The valve core detection and transporting part includes a valve core assembly detection part and a valve core transporting part, and both the valve core assembly detection part and the valve core transporting part are arranged on the workbench 5. The valve core assembly detection part includes a valve core assembly support part and a valve core detection assembly part, and the valve core assembly support part is arranged on the workbench 5, and the valve core detection assembly part is arranged on the valve core assembly support part.

[0083] The valve core assembly support comprises a seventh transmission shaft 59, a lateral transmission support frame 60, a sixth worm wheel, a fourth motor 62 and a sixth worm. One end of the seventh transmission shaft 59 rotates horizontally and passes through the fourth bracket 52, and the other end of the seventh transmission shaft 59 rotates horizontally and passes through the fifth bracket 64 on the workbench 5. The lateral transmission support frame 60 is cross-shaped, and the center of the lateral transmission support frame 60 is fixedly sleeved on the seventh transmission shaft 59. Two lateral transmission support frames 60 are symmetrically distributed on both sides of the first spring clamping positioning member on the seventh transmission shaft 59.

[0084] The valve core detection assembly includes a valve core push clamp and a spring push clamp, both of which are arranged on the lateral transmission support frame 60. The valve core push clamp includes a first push clamp 65 and a valve core push rod 66, the first push clamp 65 is arranged on a top end of the lateral transmission support frame 60, and the axis of the first push clamp 65 can coincide with the axis of the spring positioning groove 29 moved to the lower end. The first push clamp 65 includes a clamping fixed tube, a second magnetic coil and a clamping shaft, the clamping fixed tube is fixedly arranged on a top end of the lateral transmission support frame 60, and the axis of the clamping fixed tube can coincide with the axis of the spring positioning groove 29 moved to the lower end. The second magnetic coil is fixedly embedded in the clamping fixed tube, and the clamping shaft is axially slidably embedded in the clamping fixed tube. One end of the valve core push rod 66 is horizontally fixed on the end surface of the clamping shaft to axially push the head 3 of the valve core 2 inserted into the spring 1. Furthermore, the diameter of the valve core push rod 66 is smaller than the inner diameter of the spring 1. When the valve core 2 is not inserted into the spring 1, the valve core push rod 66 will be inserted into the spring 1. At this time, the axial pressure detected by the pressure sensor connected between the valve core push rod 66 and the clamping shaft is less than a predetermined value. At this time, the second magnetic coil is controlled to pass reverse direct current to generate a magnetic field to shrink the clamping shaft into the clamping fixed tube, that is, to pull the valve core push rod 66 out of the spring 1, so that the unqualified spring 1 naturally falls into the waste collection box on the workbench 5, which plays the role of detecting the injector valve core.

[0085] Further, the valve core push clamp is provided with four, and the four valve core push clamps are distributed one by one on the four top ends of one of the lateral transmission support frames 60. As an option, the valve core push clamp can also be a micro electric push rod to meet the automatic telescopic requirements.

[0086] The spring push clamp includes a second push clamp 67 and a spring push rod 68. The second push clamp 67 is arranged on a top end of another lateral transmission support frame 60, and the axis of the second push clamp 67 can coincide with the axis of the spring positioning groove 29 moved to the lower end. The second push clamp 67 has the same structure as the first push clamp 65, and one end of the spring push rod 68 is fixedly arranged on the second push clamp 67 to push the spring 1 moved to the lower end. The axis of the second push clamp 67 coincides with the axis of the first push clamp 65. Furthermore, the diameter of the spring push rod 68 is larger than the inner diameter of the spring 1 and smaller than the outer diameter of the spring 1, so as to cooperate with the valve core push rod 66 to push and clamp at the end of the spring 1.

[0087] It should be noted that, when the valve core 2 inserted into the spring 1 is released by the valve core positioning groove 51 of the valve core clamping drive belt 46, it continues to move downward to a predetermined position, and when the valve core axis coincides with the axis of the spring pushing clamp, the valve core pushing clamp presses against the head 3 of the valve core, and at the same time, the spring pushing clamp presses against the free end of the spring, so as to completely insert the cylindrical portion 4 of the valve core 2 into the spring 1 (at this time, the assembly of the injector valve core is completed), and clamp the assembled injector valve core axially; after the assembled injector valve core is transferred to the top of the valve core transport component by the spring pushing clamp, the injector valve core is released, so that the injector valve core falls on the valve core transport component and is transported to the next process. When the spring 1 or the valve core is missing from the injector valve core clamped by the valve core pushing clamp and the spring pushing clamp, it cannot be clamped by the valve core pushing clamp and the spring pushing clamp, so that it falls into the waste collection box after being released downward from the spring clamping positioning part, so as to detect the injector valve core.

[0088] The valve core transfer part includes a micro conveyor 69, which is correspondingly arranged on the workbench 5 and is used to receive the assembled fuel injector valve core clamped by the valve core assembly detection part and transfer the assembled fuel injector valve core to the next process.
