[0068] Furthermore, the first robotic arm 34, the second robotic arm 36, and the third robotic arm 35 implement their respective functions through programming.

[0069] Specifically, in the initial state, the clamping plate 8 is in a vertical position, the tension spring is stretched and at its shortest length, the extrusion plate 21 is at its lowest position, the first breaking assembly S3 is in an open state, that is, the end of the clamping plates 14 that are close to each other is at its highest position, the guide pin 43 is driven by the mini cylinder 40 and is inserted into the bayonet 44, the turntable 45 is positioned, the connector 115 and the push pin 116 are at the rightmost position, the third push block 89 and the reciprocating cylinder 112 are at the leftmost position, and the extrusion head 91 is at the lowest position under the elastic force of the spring 94. At this time, the extrusion head 91 can block the positioning pin 113, that is, the lowest point of the extrusion head 91 is lower than the highest point of the positioning pin 113.

[0070] When a breakage operation is required, the original wiper component 29 is placed on the support assembly S4, and the protrusion 22 can be engaged in the lower n-shaped groove of the original wiper component 29. Then, the first motor 3 is started, which causes the rotating shaft 7 to rotate and drive the first breakage assembly S3 to flip towards the original wiper component 29. At the same time, the pressure plate 8 flips to a horizontal position. Then, the second cylinder 30 is started, which pushes the push plate 32 upward and presses the end of the pressure plate 8 away from the first fixing bracket 2. At this time, the entire first breakage assembly S3 is broken. 3. Under the torque of the clamping plate 8, the original wiper part 29 is pressed down, that is, the original wiper part 29 is pressed onto the bearing strip 23 and the support strip 25 by the clamping plate 14 and the soft rubber strip 12; at this time, under the action of the tension spring, the close-to-each end of the second compression bearing 13 is pressed against the front and rear sides of the original wiper part 29, and the excess material on both sides of the original wiper part 29 is pressed down; then the first cylinder 17 is activated, and the push plate 27 moves upward and pushes the first top plate 20 upward, thereby... The extrusion plate 21 moves upward, causing the extrusion block 28 and the first extrusion bearing 24 to move upward as well. The first extrusion bearing 24 then pushes upward the excess material on both sides of the original wiper part 29. Since the center of the original wiper part 29 is compressed and fixed, the excess material on both sides of the original wiper part 29 will be bent upward under the push of the first extrusion bearing 24. Simultaneously, the second extrusion bearing 13 will be pushed upward, causing the extrusion plate 10 to flip upward, and the tension spring will be stretched again and store energy. At this time, the first cylinder 17 is controlled to retract, and the extrusion plate 21 will fall back under its own weight. Under the tension of the tension spring, the second extrusion bearing 13 will flip downward again and extrude the excess material on both sides of the original wiper part 29, achieving one reciprocating bending operation. Through the continuous lifting and retraction of the first cylinder 17, the reciprocating bending operation of the original wiper part 29 can be achieved until the excess material is broken, completing the breaking operation of the original wiper part 29. Figure 4 (Direction is the reference point)

[0071] Then, the broken wiper parts are continuously transported to the assembly mechanism B by the first robotic arm 34 and the second robotic arm 36 under the program control. The assembly parts transported on the left and right sides are different.

[0072] At this point, the wiper mounting part 54 is installed onto the top of the first push block 49. This step is completed by automated equipment.

[0073] When installation is required, the fourth cylinder 50 is activated, causing the first push block 49 to move upwards, thus pushing the wiper mounting part 54 mounted on the first push block 49 to its uppermost position. Then, the third cylinder 52 is activated, pushing the ejector pin 56 to the right, which in turn pushes the wiper mounting part 54 to the right and engages it inside the wiper component, completing the installation of the wiper mounting part 54. The third cylinder 52 then retracts. Next, the mini cylinder 40 moves the guide pin 43 out of the slot 44, allowing the turntable 45 to rotate. The second motor 39 is then activated, driving the turntable 45 to rotate until the next wiper component is moved to the installation position. Simultaneously, the mini cylinder 40 is activated and pushes the guide pin 43 into the slot 44, repositioning the turntable 45 and completing one installation cycle. Figure 16 (Direction is the reference point)

[0074] The assembly mechanism B on the right does not perform assembly operations; it only completes the conveying and cyclical operation of the wiper parts.

[0075] Then, the third robotic arm 35, controlled by the program, transports the wiper parts to the assembly line mechanism A. While transporting them to the assembly line mechanism A, the two wiper parts are reassembled to form a wiper mechanism, and then the next step of riveting is prepared.

[0076] The initial state of the assembly line mechanism A is as follows: the notch of the processing table S9 is on the front left side, so at this time the second cylinder plate 71 is located on the far right, the limiting component S13 is located on the far right, and the first cylinder plate 86 is located on the far right. When the processing table S9 moves, the second rodless cylinder 69 is activated, so the second cylinder plate 71 will move to the left and drive the front actuating component 68 to move to the left. Since the front actuating component 68 faces left, the actuating component 68 will drive the processing table S9 to move to the left. At this time, the movement of the processing table S9 is as follows: the actuating component 68 contacts the first stop 82 on the left side of the processing table S9 on the front right side, and then the actuating component 68 pushes the first stop 82, thereby moving the processing table S9 on the front right side to the left and driving the first cylinder plate 86 on the front middle side to move to the left. The machining table S9 moves to the far left to fill the gap, which is now located on the right front side. Simultaneously, the movement of the second cylinder plate 71 on the front side will cause the limiting component S13 to move to the left, thus moving the limiting plate 81 along with the machining table S9 to ensure stable feed of the machining table S9. At the same time, the second cylinder plate 71 on the rear side will also move to the left, preparing for the next driving action. Since the rear actuating component 68 faces right, as the actuating component 68 moves, the fifth cylinder 70 starts and pushes the push rod 76, causing the dial wheel 74 to flip upwards until it can no longer contact the first stop 82, until the second cylinder plate 71 on the rear side also moves to the far left. At this point, one feed operation is completed. Since the gap is now on the right front side, The right-side actuating component 68 will move forward under the drive of the first rodless cylinder 80, and the right-side actuating component 68 will face forward. At this time, the actuating component 68 will push the second stop 83 to drive the machining table S9 forward. At the same time, the left-side actuating component 68 will also move forward to prepare for the next driving action. Similarly, the left-side actuating component 68 will face backward. By cooperating with the fifth cylinder 70, the left-side actuating component 68 will be moved to the front. At this time, the one-step feed operation is completed. At this time, the notch is located on the right rear side. Then, the second rodless cylinder 69 on the rear side is activated. Since the rear-side actuating component 68 faces right, the rear-side actuating component 68 will drive the left rear-side machining table S9 through the right first stop 82 of the left rear-side machining table S9. 9. Move to the right, thereby simultaneously pushing the middle and rear processing table S9 to the rightmost end; at the same time, the front actuating component 68 will also move to the right and reset, and under the drive of the front second cylinder plate 71, the limiting component S13 will move synchronously to ensure the stability of the processing table S9 when moving to the right; at this time, one-step feed operation is completed; at this time, the notch is located on the left rear side, so similarly, the left actuating component 68 moves to the front side, and then the left actuating component 68 is moved backward, which can drive the left front processing table S9 to move backward, and at the same time the right actuating component 68 will also move backward and reset, completing a total of four steps of operation; realizing the infinite cycle of the processing table S9, thereby continuously sending the assembled wiper mechanism to the directly below the rivet mechanism E;Then the lifting assembly S12 is activated, which lifts the processing table S9, that is, lifts the assembled wiper mechanism on the processing table S9, in preparation for the riveting operation; during the movement of the processing table S9, the side plate 59 also provides a limiting effect, and the bullseye bearing 60 provides support and reduces friction throughout the process; (with); Figure 23 (Direction is the reference point)

[0077] After the wiper component moves upward, it contacts the pressing head 91 and pushes the pressing head 91 upward a certain distance. At this time, the spring 94 is compressed, and the pressing head 91 also presses the wiper component tightly. Then, the seventh cylinder 109 is activated, and the output end of the seventh cylinder 109 extends and drives the third push block 89 and the slider 90 to move to the right through the first connecting rod 110 and the second connecting rod 111 until the third push block 89 is blocked by the third stop block 88. At this time, the reciprocating cylinder 112 moves to the rearmost side, and the positioning pin 113 passes through the rivet hole 96. At this time, the third push block 89 moves to the far right, and the first connecting rod 110 and the second connecting rod 111 maintain a 180° angle and abut against the abutting block 106. Then, the electric cylinder 114 is activated, and the connecting head 115 moves to the left and drives the push pin 116 to move to the left. Then, the push pin 116 passes through the abutting copper sheet 102 and the guide tube. 104 and push the rivet 101 in the guide tube 104 to the left; then the rivet 101 abuts against the positioning pin 113, and as the rivet 101 continues to move to the left, the positioning pin 113 will be continuously pushed to the left. Gradually, the rivet 101 pushes the positioning pin 113 out of the rivet hole 96, and then the rivet 101 passes through the rivet hole 96. When the positioning pin 113 moves to the leftmost position, the positioning pin 113 acts as a pin to restrict the rivet 101 from moving further to the left. As the pusher pin 116 continues to push, the left end of the rivet 101 will gradually deform until the riveting operation is finally completed, and the rivet 101 is driven into the rivet hole 96, completing the riveting operation of the wiper parts. After riveting, it can be restored to the initial state, and the next rivet 101 is added through the adding tube 103; (with Figure 35 (Direction is the reference point)

[0078] When the riveted wiper mechanism is transported out by the conveyor belt mechanism A and moved directly below the unloading mechanism D, the eighth cylinder 119 is activated and drives the first connecting plate 120 to move down, which in turn drives the clamping cylinder 121 to move down. Then the clamping cylinder 121 clamps the wiper mechanism. Then the third rodless cylinder 118 is activated and drives the clamping cylinder 121 to move to the left, thereby driving the assembled and riveted wiper mechanism to move to the left until the wiper mechanism moves out of the conveyor belt mechanism A. Then the wiper mechanism can be released by the clamping cylinder 121 to put down the wiper mechanism, thus realizing the unloading operation of the wiper mechanism.

[0079] At this point, the entire assembly line operation of gradually assembling the original wiper parts 29 into the wiper mechanism has been completed.
