[0051] At the mandrel pre-installation station, the mandrel installation mechanism inserts the electrode end of the mandrel into the mandrel pre-installation hole A14-1-3 of the installation positioning plate A14-1. At the small insulating pad pre-installation station, the first insulating pad installation mechanism sleeves the small insulating pad onto the riveted end of the mandrel to form a first component. At the mandrel assembly station, the first component transfer mechanism sleeves the clamped third component onto the first component to form a fourth component. At the large insulating pad assembly station, the second insulating pad installation mechanism installs the large insulating pad onto the boss at the small end of the insulating shell of the fourth component. At the second power pin assembly riveting station, the second power pin clamping mechanism sleeves the second power pin onto the top of the large insulating pad, and the mandrel stamping mechanism stamps the riveted end of the mandrel to achieve riveting of the mandrel and the second power pin to form a fifth component. At the unloading station, the second component transfer mechanism transfers the fifth component to the subsequent installation station.

[0052] like Fig.18 and Fig.19 As shown, the core shaft mounting mechanism A05 is mounted on the front side of the vertical plate A01-4 of the frame, and the small insulating pad mounting mechanism A06-A is mounted on the back side of the vertical plate A01-4.

[0053] like Fig.18 As shown, the mandrel installation mechanism A05 includes a mandrel feeding channel A05-4, a mandrel ejector A05-1, an ejector drive cylinder A05-2 and a guide block A05-3. The mandrel feeding channel A05-4 is provided with a feeding chute of the mandrel, and the top end of the mandrel ejector A05-1 is connected to the lower end of the piston rod of the ejector drive cylinder A05-2 through a connecting block A05-6. The guide block A05-3 is U-shaped, including an upper plate, a lower plate and a connecting plate connecting the upper plate and the lower plate. The vertical plate A01-4 and the connecting plate are fixed on the front side of the vertical plate A01-4. The front end of the mandrel feeding channel A05-4 is inserted and fixed in the groove A05-3-4 of the U-shaped guide block A05-3, and the rear end is connected to the feeding channel of the mandrel vibration disk. There is an ejector guide hole A05-3-5 on the upper plate of the guide block A05-3, and a mandrel guide hole A05-3-6 on the lower plate. The ejector guide hole A05-3-5 is coaxial with the mandrel guide hole A05-3-6. There is a blanking hole at the front end of the feed chute, and the axes of the ejector guide hole A05-3-5 and the mandrel guide hole A05-3-6 pass through the blanking hole at the front end of the feed chute. When the ejector is working, the lower part passes through the ejector guide hole A05-3-5. When the installation positioning plate A14-1 is in the mandrel pre-installation position, the mandrel pre-installation hole A14-1-3 is coaxial with the mandrel ejector A05-1. A ball head plunger A05-5 is installed on the mandrel feeding channel A05-4. The ball head plunger A05-5 is installed on the side of the front end of the mandrel feeding channel A05-4. The elastic ball head of the ball head plunger A05-5 extends into the blanking hole at the front end of the mandrel feeding channel A05-4, and clamps the mandrel at the front end of the mandrel feeding chute.

[0054] like Fig.19 As shown, the small insulating pad installation mechanism A06-A includes an insulating pad guide rod A06-1, a guide rod driving cylinder A06-2, a guide plate A06-3, an insulating pad feeding channel A06-4, a sliding support plate A06-5 and a sliding support plate driving cylinder A06-6, and the cylinder body of the guide rod driving cylinder A06-2 and the guide plate A06-3 are fixed on the back of the vertical plate A01-4. The guide plate A06-3 has a guide hole for the insulating pad guide rod A06-1, and the insulating pad guide rod A06-1 passes through the guide hole of the guide plate A06-3, and the top of the guide rod is connected to the lower end of the piston rod of the guide rod driving cylinder A06-2. The cylinder bodies of the insulating pad feeding channel A06-4 and the sliding pallet driving cylinder A06-6 are horizontally fixed on the back of the vertical plate A01-4. The insulating pad feeding channel A06-4 is provided with a feeding chute A06-4-1 for the insulating pad. The rear end of the insulating pad feeding channel A06-4 is connected to the feeding channel of the core shaft vibration plate. The front end of the sliding pallet A06-5 has a stepped, front-end open U-shaped groove A06-5-1. The sliding pallet A06-5 is fixed to the front end of the piston rod of the sliding pallet driving cylinder A06-6. When the piston rod of the sliding pallet driving cylinder A06-6 is extended, the U-shaped groove A06-5-1 of the sliding pallet A06-5 is connected to the front end of the feeding chute of the insulating pad feeding channel A06-4, and the axis of the insulating pad guide rod A06-1 passes through the inner hole of the U-shaped groove A06-5-1 of the sliding pallet A06-5. When the installation positioning plate A14-1 is in the insulating pad pre-installation position, the core shaft pre-installation hole A14-1-3 is coaxial with the insulating pad guide rod A06-1.

[0055] When the mandrel is pre-installed, the installation positioning plate A14-1 enters the mandrel pre-installation station and is located directly below the mandrel ejector pin A05-1 of the mandrel installation mechanism A05. The mandrel B01 is screened by the mandrel vibration plate (not shown in the figure) so that the riveted end faces upward and the electrode end faces downward, and then stands in a row in the opposite direction of Y and enters the mandrel feeding channel A05-4. The frontmost mandrel enters the blanking hole at the front end of the mandrel feeding channel A05-4. At this position, the middle flange of the mandrel B01 is supported by the ball head plunger A05-5, waiting for press-fitting. The piston rod of the ejector drive cylinder A05-2 of the core shaft installation mechanism A05 extends downward, the core shaft ejector A05-1 is pressed down, the flange in the middle of the core shaft B01 pushes away the elastic ball head of the ball head plunger A05-5, and the core shaft B01 passes through the blanking hole at the front end of the core shaft feeding channel A05-4 and the core shaft guide hole A05-3-6 of the guide block A05-3, and the electrode end at the lower part of the core shaft B01 is vertically inserted into the core shaft pre-installed hole A14-1-3.

[0056] When the mandrel ejector A05-1 moves downward, it blocks the mandrel B01 at the front end of the mandrel feeding channel A05-4 and continues to enter the blanking hole at the front end along the reverse direction Y. The piston rod of the ejector drive cylinder A05-2 retracts. When the mandrel ejector A05-1 moves upward, the mandrel B01 at the front end of the mandrel feeding channel A05-4 enters the blanking hole at the front end along the reverse direction Y to prepare for the next assembly. At this time, one assembly cycle of the mandrel pre-assembly station is completed.

[0057] After the mandrel is pre-installed, the installation positioning plate A14-1 is moved along the positive direction of the X-axis to the small insulating pad pre-installation station and enters directly below the guide rod A06-1 of the small insulating pad installation mechanism A06-A.

[0058] The small insulating pads B02 are screened by the insulating pad vibrating plate (not shown in the figure), and enter the insulating pad feeding channel A06-4 in the reverse direction of Y in a row. The frontmost insulating pad enters the U-shaped groove A06-5-1 of the sliding support plate A06-5.

[0059] The guide rod drives the piston rod of the cylinder A06-2 to extend downward, and the insulating pad guide rod A06-1 moves downward, passing through the inner hole of the insulating pad B02 to position it, and the lower end of the insulating pad guide rod A06-1 touches the top of the pre-installed mandrel B01. At this time, the piston rod of the sliding support plate drives the cylinder A06-6 to retract, and the sliding support plate A06-5 is pulled out in the opposite direction of Y. The insulating pad B02 falls under the action of gravity and is sleeved on the mandrel B01 on the installation and positioning main board A14-1, and is combined with the mandrel B01 to form the first component B12.

[0060] As the small insulating pad B02 falls under the action of gravity, the downward insulating pad guide rod A06-1 blocks the insulating pad in the insulating pad feeding channel A06-4 from continuing to move in the opposite direction of Y. The piston rod of the sliding pallet driving cylinder A06-6 extends forward, driving the sliding pallet A06-5 to be inserted in the positive direction of Y. The piston rod of the guide rod driving cylinder A06-2 retracts and drives the insulating pad guide rod A06-1 to withdraw. A small insulating pad at the front end of the insulating pad feeding channel A06-4 enters the U-shaped groove A06-5-1 of the sliding pallet A06-5 again, and the small insulating pad pre-installation station completes an assembly cycle.

[0061] like Fig. 20 As shown, the push-lock mechanism A03 includes a base A01-5 as part of the frame, a plug-in pin channel, an insulating shell channel A03-1, a push block A03-4, a push block driving cylinder A03-5, a linear guide pair A03-6 and a connecting block A03-5-1, a stop block A03-7 and a tension spring A03-8.

[0062] The plug-in pin channel, the insulating shell channel A03-1 and the push block driving cylinder A03-5 are installed on the base A01-5. The plug-in pin channel and the insulating shell channel A03-1 are arranged along the Y-axis direction, the rear end of the plug-in pin channel is connected to the feeding channel of the plug-in pin vibration disk (not shown in the figure), and the rear end of the insulating shell channel A03-1 is connected to the feeding channel of the insulating shell vibration disk (not shown in the figure).

[0063] The disconnect pin channel includes a guide groove A03-2 for the disconnect pin connection pin and a support plate A03-3 for the disconnect pin ring, and the front end of the support plate A03-3 has a protruding block A03-3-1. The front part of the push block A03-4 has a receiving groove A03-4-1 for the insulating shell, and the receiving groove A03-4-1 is located below the front end of the support plate A03-3 and docked with the front end of the insulating shell channel A03-1. In the opposite direction of the X-axis, the guide groove A03-2 is located in front of the insulating shell channel A03-1. The push block driving cylinder A03-5 is arranged along the X-axis direction, and the push block A03-4 is connected to the front end of the piston rod of the push block driving cylinder A03-5.

[0064] The guide rails of the linear guide pair A03-6 are installed on the frame base A01-5 and arranged along the X-axis direction. The connecting block A03-5-1 is fixed on the first slider of the linear guide pair A03-6, and the pusher block A03-4 is connected to the front end of the piston rod of the pusher block driving cylinder A03-5 through the connecting block A03-5-1.

[0065] The upper part of the stopper A03-7 includes a baffle A03-7-1. The stopper A03-7 is fixed on the second slider of the linear guide pair A03-6, and the second slider is located in front of the first slider along the opposite direction of the X-axis. One end of the tension spring A03-8 is fixed on the stopper A03-7, and the other end is fixed on the base A01-5. The tension of the tension spring A03-8 causes the second slider to move in the direction of the first slider. Along the opposite direction of the X-axis, the baffle A03-7-1 is located in front of the receiving groove A03-4-1, and the receiving groove A03-4-1 is open in the direction of the baffle A03-7-1. Along the opposite direction of the X-axis, the base A01-5 has a front limit block and a rear limit block of the stopper A03-7. When the stopper A03-7 contacts the rear limit block, the rear plane of the baffle A03-7-1 is flush with the front wall of the guide groove A03-2.

[0066] like Fig.21 As shown, the turning robot A02 comprises a rotary cylinder A02-1 and two sets of clamping mechanisms. The cylinder body of the rotary cylinder A02-1 is fixed on the frame A01 along the Y-axis direction.

[0067] Two sets of clamping mechanisms are centrally symmetrically mounted on the front end surface of the turntable A02-1-1 of the rotary cylinder A02-1. The clamping mechanism includes a pressure head A02-2, a pressure head driving cylinder A02-3, a clamping hand A02-4 and a finger cylinder A02-5. The arc-shaped clamping hand A02-4 is fixed on the finger of the finger cylinder A02-5, and the cylinder body of the finger cylinder A02-5 and the pressure head A02-2 are fixed on the end of the piston rod of the pressure head driving cylinder A02-3. The axis of the pressure head A02-2 is coaxial with the symmetry axis of the arc-shaped clamping hand A02-4.

[0068] The end of the piston rod of the ram driving cylinder A02-3 is equipped with a T-shaped connecting plate A02-3-1, and the horizontal plate of the T-shaped connecting plate A02-3-1 is fixed to the end of the piston rod of the ram driving cylinder A02-3. The cylinder body of the finger cylinder A02-5 is fixed to the horizontal plate of the T-shaped connecting plate A02-3-1, and the ram A02-2 is fixed to the vertical plate of the T-shaped connecting plate A02-3-1. The working plane of the finger cylinder A02-5 finger is orthogonal to the piston rod of the ram driving cylinder A02-3, and the axis of the ram A02-2 is parallel to the piston rod of the ram driving cylinder A02-3. The ram A02-2 is a stepped shaft, and the large shaft end of the stepped shaft is fixed on the T-shaped connecting plate A02-3-1. The diameter of the large shaft is smaller than the diameter of the inner cavity of the insulating shell B04, and the diameter of the small shaft is smaller than the diameter of the small hole B04-4 of the insulating shell. The rotary cylinder A02-1 is a two-station 180° rotary cylinder. When the push block A03-4 moves forward to the end point in the opposite direction of the X-axis, the axis of the press head A02-2 of the clamping mechanism with the piston rod of the press head driving cylinder A02-3 facing downward is coaxial with the inner hole of the insulating shell B04 in the receiving groove A03-4-1 of the push block A03-4.

[0069] The disconnect pin part B03 is screened by the disconnect pin vibration disk (not shown in the figure) into a row of connecting pins B03-1 with a vertical downward posture, entering the disconnect pin channel along the positive direction of the Y axis, and hung on the support plate A03-3, and the connecting pins B03-1 are inserted into the guide groove A03-2. The insulating shell part B04 is screened by the insulating shell vibration disk into the disconnect pin slot B04-2 facing the opposite direction of the X axis, and the flange B04-1 is in an upward posture. The frontmost insulating shell part B04 enters the receiving groove A03-4-1 of the pusher block A03-4, and the frontmost disconnect pin part B03 is blocked by the protruding block A03-3-1, just above the insulating shell part B04. Under the push of the piston rod of the push block driving cylinder A03-5, the push block A03-4 makes a linear motion in the opposite direction of the X-axis. When the push block A03-4 drives the insulating shell part B04 to move horizontally in the opposite direction of the X-axis, the connection pin B03-1 of the plug-in pin part B03 enters the plug-in pin slot B04-2 of the insulating shell part B04, and the push block A03-4 continues to move in the opposite direction of the X-axis. On the one hand, the annular ring of the plug-in pin part B03 slides out of the support plate A03-3 in the opposite direction of the X-axis, and on the other hand The pushing block A03-4 presses against the baffle A03-7-1 and moves together along the opposite direction of the X-axis. The baffle A03-7-1 blocks the connection pin B03-1 of the disconnect pin B03 so that the disconnect pin B03 can only fall vertically downward.

The structure and operation process of the large insulating pad installation mechanism A06-B are the same as those of the small insulating pad installation mechanism A06-A, and only some structural dimensions are different, which will not be described separately here. After the fourth component installs the large insulating pad B06, the installation positioning plate A14-1 continues to move along the positive direction of X to the second power pin assembly riveting station, that is, below the stamping mechanism A10.

The slide groove of the annular ring is arranged horizontally, and the slide groove of the terminal pin is arranged vertically and open at the bottom. The gap between the top surface of the support plate A09-6-2 and the bottom of the groove forms the slide groove of the annular ring of the positive pin B07. The gap between the side of the support plate A09-6-2 and the inner wall of the groove forms the slide groove of the terminal pin of the positive pin B07.

The frontmost positive pin part enters the receiving plate of the positive pin of the slide plate A09-2, and the clamping hand A09-3 clamps the connection pin of the positive pin part on the slide plate A09-2 under the slide plate A09-2. At this time, due to the obstruction of the slide plate A09-2, the positive pin part clamped by the clamping hand A09-3 cannot move up and down, and the piston rod of the slide plate driving cylinder A09-1 extends, driving the slide plate A09-2 to slide along the reverse direction of Y, so that the positive pin part clamped by the clamping hand A09-3 can move. The piston rod of the lifting cylinder A09-4 retracts to drive the finger cylinder A09-8, the clamp A09-3 and the positive pin parts on them to move downward, and then the slide drive cylinder A09-1 retracts to drive the slide A09-2 to slide along the positive direction of Y. The positive pin parts in the positive pin channel A09-6 continue to move along the negative direction of Y to the slide A09-2 to prepare for the next assembly.
