In the present embodiment, as shown in fig. 4, the pin position detection sensor 2 is a photoelectric sensor. The first material placing seat 13 is provided with a light channel 137 on the side surface of the closed end of the first material guiding pore channel 131, the photoelectric sensor 2 emits light, the tail end of the pin shaft 91 is detected, the diameter of a detection light spot is about 0.1mm, and the light channel is used for judging whether the pin shaft 91 reaches the position to be taken so as to avoid the situation that the pin shaft does not reach the position to be taken.

Please refer to fig. 7 and 8. In this embodiment, the material gripping and discharging mechanism is composed of an air gripper, which includes a gripper 310 and a first air cylinder 311, the gripper 310 is connected to the first air cylinder 311, the gripper 310 can be driven by the first air cylinder 311 to open or close, so as to grip the pin from the material taking position for measuring the length of the pin or place the pin to the sorting position after measuring the length, and fig. 5 shows a schematic diagram of the gripper 310 in the material gripping state. The lifting sub-mechanism comprises a second air cylinder 322, the first air cylinder 311 is arranged on the second air cylinder 322, and the second air cylinder 322 can drive the hand grip 310 and the first air cylinder 311 to move up and down together.

The pin length detection mechanism is used to detect a linear distance between one end of the pin 91 at the measurement position and a predetermined reference position.
Referring to fig. 6, in the present embodiment, the pin length detecting mechanism includes a fourth cylinder 44 and a displacement sensor 43 capable of moving along with the fourth cylinder 44, a measuring head 431 of the displacement sensor 43 faces an end of the pin at a measuring position, and the measuring position is located right above the material taking position. The fourth cylinder 44 is used for driving the displacement sensor 43 to move from the initial position to the measurement position, and when the displacement sensor 43 is at the measurement position, the top end of the measurement head 431 of the displacement sensor 43 abuts against one end of the pin shaft 91; the predetermined reference position is an initial position of a tip of a measuring head of the displacement sensor.
When the hand grip 310 grabs the pin shaft and moves to the measurement position, the control device controls the fourth air cylinder 44 to start, so as to drive the displacement sensor 43 to move towards the pin shaft in the hand grip, and when the top end of the measuring head 431 of the displacement sensor 43 abuts against one end of the pin shaft, the displacement sensor 43 cannot move forward any more. At this time, the displacement sensor 43 measures the distance from the initial position of the tip of the measuring head 431 to the end of the pin 91. Since the pin 91 abuts against the closed end of the first material guiding hole 131 when being in the first material guiding hole 131, and then the pin does not displace in the moving direction of the fourth cylinder 44, the distance from the initial position of the top end of the measuring head 431 of the displacement sensor 43 to the other end of the pin at the measuring position is fixed and known, and the difference between the two distances is the length of the pin 91. After the displacement sensor 43 sends the measurement result to the control device, the control device can calculate the length of the pin shaft 91 according to the measurement result, and compare the length of the pin shaft with the pre-stored standard pin shaft length to judge whether the length of the pin shaft is qualified.
Preferably, measuring head 431 is the elasticity measuring head, and its inside is provided with the spring, and when the butt round pin axle, measuring head 431 can receive the atress shrink, because the power that the round pin axle was snatched to the cylinder is greater than the elasticity of spring far away, has consequently avoided the round pin axle to be promoted by measuring head 431 and lead to the condition of sliding.

Optionally, the top surface of the second discharging seat 51 is provided with a second groove 515 perpendicularly intersecting the second material guiding hole 512, and the second groove 515 is used for the hand grip 310 to move therein and grip the pin shaft 91.
The first pushing mechanism is used to extend into the second material guiding duct 512 from the inner end of the second material guiding duct 512, so as to push the pin shaft 91, which is located at the sorting position and has an unqualified length, out of the outer end of the second material guiding duct 512. In this embodiment, the first pusher mechanism includes a thimble 523 and a fifth cylinder 525. The thimble 523 is connected to the top end of the push rod of the fifth cylinder 525, and the thimble 523 aligns with the inner end of the second material guiding hole 512.
The shielding member 53 is pivotally connected to an outer side of the second discharging base 51. The qualified product receiving mechanism is used for receiving the pin shaft with qualified length. The non-defective product receiving mechanism includes a non-defective product storage section 541 and a storage section driving mechanism. The qualified product storage component 541 is provided with a discharging through hole 5410, the storage component driving mechanism is used for driving the qualified product storage component 541 to move between an installation position and a material receiving position, in the process that the qualified product storage component 541 moves from the installation position to the material receiving position, the qualified product storage component 541 drives the shielding component 53 to rotate, when the qualified product storage component 541 is in the material receiving position, the shielding component 53 shields the outer side end of the discharging through hole 5410, and the inner side end of the discharging through hole 5410 is opposite to the outer side end of the second material guiding hole 512.
In this embodiment, the shutter 53 is a U-shaped block, the non-defective product storage 541 is a slider, and the storage drive mechanism includes an eighth cylinder 548.

The outer end of the second guide passage 512 is opened to the side 5161 of the recess 516. The U-block 53 includes a first bifurcating arm 531, a second bifurcating arm 532, and a base portion 533 connected between the first bifurcating arm 531 and the second bifurcating arm 532, the first bifurcating arm 531 has an acting portion 5311 protruding to one side in the thickness direction, the base portion 533 is provided with a pivot hole 5330 pivotally connected to the outer side surface of the second discharging holder 51 by a pivot passing through the pivot hole 5330, the first bifurcating arm 531 is located above the second bifurcating arm 532, the acting portion 5311 of the first bifurcating arm 531 partially protrudes into the recess 516, and the acting portion 5311 of the first bifurcating arm abuts against a joint edge between the bottom surface of the recess 516 and the top surface of the second discharging holder, thereby holding the U-block 53 at the initial position.
After the hand grip 310 puts the pin shaft into the second material guiding hole 512 through the discharging hole 513 of the second discharging seat 51, if the length of the pin shaft is qualified, the pin shaft stays at the sorting position to wait for taking. If the length of the pin shaft is not qualified, the control device controls the fifth cylinder 525 to push the thimble 523, the thimble 523 extends into the second material guiding pore passage 512 from the inner side end of the second material guiding pore passage 512, and pushes the pin shaft in the second material guiding pore passage 512 to drop into the defective product box 8 serving as the unqualified product storage component below from the outer side end of the second material guiding pore passage 512. Since the U-shaped block 53 naturally hangs down obliquely at the initial position, the U-shaped block 53 does not prevent the unqualified pin from being pushed out when the unqualified pin is pushed out from the second material guiding passage 512.
When the pin shaft is qualified, the control device controls the eighth cylinder 548 to drive the qualified product storage component 541 to move from the installation position to the material receiving position, and when the qualified product storage component 541 is in the material receiving position, the inner side end of the discharge through hole 5410 is just aligned with the outer side end of the second material guide duct 512.

Subsequently, the non-defective product storage unit 541 is reset by the eighth cylinder 548.
The pin mounting mechanism is used to mount the pin placed in the non-defective product storage component 541 into an assembly target object. The pin shaft installation mechanism comprises a second material pushing sub-mechanism and a displacement driving sub-mechanism. The displacement driving sub-mechanism is used for driving the qualified product receiving mechanism and the second material pushing sub-mechanism to move between the initial position and the preset assembling position; the second material pushing mechanism is used for extending into the discharging through hole of the qualified product storage component at the mounting position from the inner side end of the discharging through hole so as to push the pin shaft in the discharging through hole out of the outer side end of the discharging through hole.
In this embodiment, the second material pushing mechanism includes a thimble 613 and a sixth cylinder 616, and the thimble 613 is connected to a push rod of the sixth cylinder 616. The displacement driving sub-mechanism includes a guide rail 621, a moving table 623, and a seventh cylinder 627.

Optionally, the displacement driving sub-mechanism further comprises a limiting device, and the limiting device is used for ensuring that the moving table 623 does not collide with an assembly target object when moving, and the assembly target object is a vehicle-mounted power supply semi-finished product.
Further, the pin mounting mechanism includes an index plate feed mechanism for conveying an assembly target object to which the pin is to be assembled to a predetermined assembly position.
Please refer to fig. 12. The mobile station 623 is initially at a home position. When the moving table 623 is at the home position, the non-defective product storage member 541 moves and takes up the pin. When the non-defective product storage unit 541 is reset to the mounting position, the thimble 613 is just aligned with the inner side end of the discharge through hole 5410 of the non-defective product storage unit 541. Subsequently, the control device controls the seventh cylinder 627 to push the moving table 623 to move on the guide rail 621, and the moving table 623 moves from the starting position (at this time, the non-defective product storage component 541 is away from the vehicle-mounted power supply semi-finished product 92 on the index plate) to the assembling position. When the moving table 623 reaches the assembly position, the vehicle-mounted power supply semi-finished product 92 to be provided with the pin shaft is also moved to the assembly position by the index plate feeding mechanism, and at this time, the pin shaft mounting hole on the vehicle-mounted power supply semi-finished product 92 is just aligned with the outer side end of the discharging through hole 5410 of the qualified product storage component 541. Subsequently, the control device controls the sixth air cylinder 616 to push the thimble 613, and the thimble 613 pushes the pin into the pin mounting hole of the vehicle-mounted power supply semi-finished product 92 from the discharging through hole 5410. After the pin is installed in the vehicle-mounted power supply semi-finished product 92, the control device controls the seventh cylinder 627 to retract, and the mobile station 623 is reset from the assembly position to the initial position. Then, the index plate rotates to perform the next feeding.

When the photoelectric sensor 2 senses that the pin shaft reaches the material taking position, a pin shaft in-place signal is sent to the PLC 71. When receiving the pin roll in-place signal, the PLC controller 71 controls the third cylinder 333 to move rightward, so that the gripper 310 moves to a position right above the material taking position. The first air cylinder 311 controls the gripper 310 to open, the second air cylinder 322 extends downwards, and after the gripper 310 is closed, the first air cylinder 311 controls the pin shaft 91 at the material taking position to grab. Subsequently, the second cylinder 322 is retracted upward until the pin 91 reaches the measurement position. The PLC controller 71 controls the fourth cylinder 44 to extend, so that the top end of the measuring head 431 of the displacement sensor 43 abuts against one end of the pin shaft at the measuring position, thereby realizing the measurement. Then, the PLC controller 71 controls the third air cylinder 333 to move leftward, so that the gripper 310 moves to a position right above the sorting position, the second air cylinder 322 extends downward, and when the gripper is in place, the first air cylinder 311 controls the gripper 310 to open, and the pin shaft 91 is placed at the sorting position. The PLC controller 71 judges whether the length of the pin shaft at the sorting position is qualified according to the detection result of the displacement sensor, and if the length of the pin shaft is unqualified, only the fifth cylinder 525 is started, and the pin shaft with the unqualified length is ejected into the unqualified product box 8 by the ejector pin 523; if the qualified products are judged to be qualified, the PLC 71 controls the eighth cylinder 548 to start to push the qualified product storage component 541 to the receiving position, and then the fifth cylinder 525 pushes the thimble 523 to push the pin shaft into the discharging through hole 5410 of the qualified product storage component 541. After the fifth cylinder 525 and the eighth cylinder 548 are reset to the proper positions, the PLC controller 71 controls the seventh cylinder 627 to push the moving table 623 to move to the assembling position. After the moving table 623 moves to the assembling position, the sixth air cylinder 616 pushes the thimble 613, the thimble 613 pushes the pin into the pin mounting hole of the vehicle-mounted power supply semi-finished product 92 from the material placing through hole 5410, the assembling is completed, and the sixth air cylinder 616 and the seventh air cylinder 627 are reset.
