At present, car seats are generally assembled using a belt assembly line. The belt assembly line assembly method is: single seats, double seats and long seats are assembled on the same assembly line at the same time. Due to the different shapes of single seats, double seats and long seats, the assembly processes of single seats, double seats and long seats are slightly different. In addition, in the initial assembly process of car seats, different types of seats are not very different, which makes it easy for workers to distinguish different seats. In addition, when the belt assembly line assembly method was used to assemble car seats in the past, workers had to switch between different workstations due to assembly process requirements, resulting in low assembly efficiency of car seats, which in turn affected the overall cost of car seats.

DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] See also Figure 1 and Figure 6, shows a production line pallet rotation classification system of a preferred embodiment of the present invention, which includes a conveying mechanism 1, a first pallet 2, a second pallet 3, a blocker 4, a trigger assembly 5, a push rod mechanism 6, a rotation drive assembly 7, a lifting drive assembly 8 and a positioning assembly 9.

[0030] The conveying mechanism 1 includes a frame 11 and a belt conveyor 12 provided on the frame 11. The belt conveyor 12 is used to drive the first pallet 2 and the second pallet 3 to move along the extension direction of the belt conveyor 12. The first pallet 2 and the second pallet 3 each include a base plate, a positioning plate and a support plate. The positioning plate connects the base plate and the support plate. The support plate and the positioning plate are pivotally connected so as to be able to rotate around the positioning plate. During operation, the base plate fits against the belt conveyor 12. The support plate is used to support workpieces. To facilitate supporting workpieces of different shapes, the outer contour dimensions of the support plate of the first pallet 2 are larger than the outer contour dimensions of the support plate of the second pallet 3. In actual applications, the size of the workpiece supported by the support plate of the first pallet 2 is larger than the size of the workpiece supported by the support plate of the second pallet 3.

[0031] like Figure 1 and Figure 2 As shown, the blocker 4 is provided on the first side of the frame 11, and the extending direction of the blocker 4 is perpendicular to the conveying direction of the belt conveyor 12 or is inclined at a certain angle, as shown in FIG. Figure 1 and Figure 3 As shown, the push rod mechanism 6 is arranged on the second side of the frame 11, and the push rod mechanism 6 includes a push rod 61 and a push rod driving member, wherein the push rod driving member is a cylinder 62, and the cylinder 62 is fixed to the second side of the frame 11, and the piston rod of the cylinder 62 is fixedly connected to the push rod 61. When the first pallet 2 passes through the blocker 4 under the movement drive of the belt conveyor 12, the blocker 4 abuts against the side wall of the support plate of the first pallet 2, and then drives the support plate of the first pallet 2 to rotate for the first time under the abutment and pushing action of the blocker 4. When the first pallet 2 passes through the push rod mechanism 6, the push rod 61 is extended by the drive of the push rod driving member and abuts against the side wall of the support plate of the first pallet 2, and then drives the support plate of the first pallet 2 to rotate for the second time. The direction of the first rotation is the same as the direction of the second rotation.

[0032] When the pallet of the first pallet 2 rotates for the first time, due to the dual action of the moving drive of the belt conveyor 12 and the abutment and pushing action of the blocker 4, the pallet of the first pallet 2 can be rotated 90 degrees around the positioning disk. When the pallet of the first pallet 2 rotates for the second time, due to the dual action of the moving drive of the belt conveyor 12 and the abutment and pushing action of the push rod mechanism 6, the pallet of the first pallet 2 can be rotated 90 degrees around the positioning disk of the first pallet 2 again. Since the first rotation direction is the same as the second rotation direction, after the abutment and pushing action of the blocker 4 and the push rod mechanism 6, the pallet of the first pallet 2 can be rotated 180 degrees around the positioning disk. During the assembly process, after the pallet of the first pallet 2 rotates 180 degrees, the pallet of the first pallet 2 can drive the assembly part of the first workpiece to turn towards the worker, which is convenient for the worker to assemble the workpiece, avoids the worker from changing workstations multiple times due to the different directions of the assembly part, and improves the assembly efficiency of the worker. Since the outer contour dimensions of the pallet of the second pallet 3 are smaller than the outer contour dimensions of the pallet of the first pallet 2 , when the pallet of the second pallet 3 passes through the stopper 4 , the pallet of the second pallet 3 will not contact the stopper 4 .

[0033] like Figure 1 、 Figure 4 and Figure 5 As shown, the lifting drive assembly 8 includes a first turntable 82 connected to each other and a guide block 81 with an inclined surface. The first end of the rotation drive assembly 7 slides with the inclined surface. When the second tray 3 passes through the first turntable 82, the first turntable 82 rotates and then drives the guide block 81 to slide along the first direction. The guide block 81 slides and drives the rotation drive assembly 7 to move upward along the inclined surface. When it rises to the right position, the positioning assembly 9 locks the rotation drive assembly 7. When the second tray 3 passes through the rotation drive assembly 7, the second end of the rotation drive assembly 7 abuts against the side wall of the support plate of the second tray 3, and then drives the support plate of the second tray 3 to rotate. When the support plate of the second tray 3 is disengaged from the rotation drive assembly 7, the positioning assembly 9 is unlocked and the rotation drive assembly 7 is reset, that is, the rotation drive assembly 7 is at the lowest position of the inclined surface.

[0034] During the workpiece assembly process, since the second pallet 3 is driven to move by the belt conveyor 12, when the second pallet 3 moves to the position of the first turntable 82 under the drive of the belt conveyor 12, the second pallet 3 drives the first turntable 82 to rotate and then drives the guide block 81 to slide along the first direction, and since the first end of the rotation drive assembly 7 is in sliding cooperation with the inclined surface of the guide block 81, the rotation drive assembly 7 is driven to move upward under the sliding of the guide block 81, so that the second end of the rotation drive assembly 7 can abut against the support plate of the second pallet 3. While the support plate of the second pallet 3 moves along the extension direction of the belt conveyor 12, the second pallet 3 The support plate of the tray 3 is blocked by the rotating drive assembly 7, so the support plate of the second tray 3 can drive the second workpiece to rotate 90 degrees, so that the assembly part of the second workpiece can be turned towards the worker, which is convenient for the assembly of the workpiece. During the assembly process, it avoids the need for workers to change workstations due to different assembly parts of the workpiece, thereby improving the assembly efficiency of the workpiece and reducing the assembly cost of the workpiece. In addition, this method of using the support plate of the second tray 3 to drive the first turntable 82 can realize the rotation of the support plate of the second tray 3 without the need for additional power sources. The design is more clever and helps to reduce the cost of the pallet rotation classification system of the production line.

[0035] The production line pallet rotation classification system of this embodiment can facilitate the distinction between the first workpiece and the second workpiece by causing the pallet of the first pallet 2 to rotate 180 degrees, and by causing the pallet of the second pallet 3 to rotate the second workpiece 90 degrees, thereby ensuring the correct assembly of the first workpiece and the second workpiece and improving assembly efficiency. In addition, the assembly parts of the first workpiece and the second workpiece can be directed towards the workers at their respective assembly stations, which facilitates the assembly of the workpieces and further improves assembly efficiency.

[0036] To facilitate the start or stop of the driving cylinder 62, the production line pallet rotation classification system also includes a controller. The trigger component 5 is arranged on the first side of the frame 11 and close to the blocker 4. The trigger component 5 includes a limit switch 51 (the specific model of the limit switch 51 is WLCA12-2-N). The limit switch 51 and the cylinder 62 are both electrically connected to the controller. The controller is used to receive feedback from the limit switch 51 and to control the action of the cylinder 62. When the first pallet 2 approaches the blocker 4 and starts the first rotation, the support plate of the first pallet 2 abuts against the limit switch 51, thereby triggering the limit switch 51. The controller receives the feedback information of the limit switch 51 and starts timing. When the first pallet 2 passes through the push rod mechanism 6, the timing ends, and the controller controls the start of the cylinder 62. The push rod 61 is pushed by the cylinder 62 and extends in the direction close to the middle position of the belt conveyor 12 and abuts against the support plate of the first pallet 2.

[0037] In actual application, the distance between the support plate of the first pallet 2 and the push rod mechanism 6 is large after the first rotation. If the push rod mechanism 6 is set to a fixed structure, it is difficult for the push rod mechanism 6 to contact the support plate of the first pallet 2 and rotation cannot be achieved. Therefore, in order to ensure that the push rod mechanism 6 of the fixed structure is in contact with the support plate of the first pallet 2, the push rod mechanism 6 of the fixed structure should be set close to the middle of the belt conveyor 12. However, when the second pallet 3 passes the position of the push rod mechanism 6 of the fixed structure, the support plate of the second pallet 3 contacts the push rod mechanism 6 of the fixed structure, that is, when the support plate of the second pallet 3 passes the push rod mechanism 6 of the fixed structure, the support plate of the second pallet 3 also rotates. Such a setting is bound to be unfavorable for distinguishing the workpieces supported by the first pallet 2 and the second pallet 3, resulting in confusion between the workpieces supported by the first pallet 2 and the second pallet 3, which is not conducive to assembly. Therefore, in this embodiment, the push rod mechanism 6 is set to a retractable structure driven by a push rod driving member.

[0038] The trigger assembly 5 may also include a third guide wheel 52, which is installed on the limit switch 51. The third guide wheel 52 slides with the side wall of the support plate of the first pallet 2. When the support plate of the first pallet 2 rotates for the first time, it slides with the third guide wheel 52 while rotating. While triggering the limit switch 51, the friction between the limit switch 51 and the support plate of the first pallet 2 can be reduced, so that the rotation of the support plate of the first pallet 2 is smooth. When the support plate of the first pallet 2 is disconnected from the third guide wheel 52, the limit switch 51 is closed.

[0039] The blocker 4 includes an extension plate 41 and a first guide wheel 42 provided on the extension plate 41. The extension direction of the extension plate 41 is perpendicular to the moving direction of the belt conveyor 12. When the first pallet 2 passes through the blocker 4, the first guide wheel 42 abuts against the support plate of the first pallet 2 to reduce the friction between the extension plate 41 and the support plate of the first pallet 2, so that the rotation of the support plate of the first pallet 2 is smooth.

[0040] The push rod 61 is provided with a fourth guide wheel 63. When the first pallet 2 passes through the push rod mechanism 6, the fourth guide wheel 63 abuts against the support plate of the first pallet 2 to reduce the friction between the push rod 61 and the support plate of the first pallet 2, which is beneficial to the rotation of the support plate of the first pallet 2 and the movement of the first pallet 2.

[0041] To facilitate the directional extension of the push rod 61, a third guide mechanism is provided on the second side of the frame 11. The third guide mechanism includes a third guide rail 65 and a third slider 64. The third slider 64 is fixedly connected to the push rod 61, and the third guide rail 65 is fixedly connected to the second side of the frame 11. The third slider 64 and the third guide rail 65 are slidably engaged.

[0042] To facilitate the resetting of the rotary drive assembly 7, the production line pallet rotary sorting system also includes a second turntable 10, which is connected to the positioning assembly 9; the lifting drive assembly 8 also includes a reset drive member for driving the guide block 81 to slide along the second direction. It can be understood that the first direction is opposite to the second direction. When the second pallet 3 passes through the second turntable 10, the second turntable 10 rotates under the drive of the second pallet 3, thereby driving the positioning assembly 9 to unlock the rotary drive assembly 7. At the same time, the guide block 81 slides along the second direction under the action of the reset drive member, thereby driving the rotary drive assembly 7 to descend along the inclined surface. This method of using the support plate of the second pallet 3 to drive the second turntable 10 can achieve the resetting of the rotary drive assembly 7 without adding other power sources. The design is relatively clever, further reducing the cost of the production line pallet rotary sorting system. Of course, the resetting of the rotary drive assembly 7 can also be achieved by manually eliminating the resistance of the positioning assembly 9 to the rotary drive assembly 7.

[0043] In order to facilitate driving the first turntable 82 and the second turntable 10, a pin shaft 31 is provided on the bottom plate of the second pallet 3. The pin shaft 31 is used to abut against the first turntable 82 or the second turntable 10 to drive the first turntable 82 and the second turntable 10 to rotate. In addition, by providing the pin shaft 31 on the second pallet 3, it is convenient for workers to distinguish between the first pallet 2 and the second pallet 3.

[0044] Among them, the second turntable 10 includes a second rotating rod 102 and a second winding wheel 101 arranged on the second rotating rod 102. The second rotating rod 102 is pivotally connected to the connecting tube of the second side wall of the frame 11 in the conveying mechanism 1. The second winding wheel 101 is connected to the positioning component 9 by a connecting line or a connecting rope. When the second tray 3 passes through the second turntable 10, the pin 31 of the second tray 3 abuts against the second rotating rod 102. The second rotating rod 102 rotates under the abutment of the pin 31, thereby driving the second winding wheel 101 to reel in the connecting line or connecting rope. Under the pulling action of the connecting line or connecting rope, the positioning component 9 unlocks the rotation drive component 7, that is, the abutment effect of the positioning component 9 on the rotation drive component 7 disappears.

[0045] The reset drive member is a counterweight block 83, and the first side wall of the frame 11 in the conveying mechanism 1 is provided with a sliding mechanism 84, which is a winding wheel assembly. Another connecting line or connecting rope is wound between the winding wheel assemblies. The counterweight block 83 and the guide block 81 are connected by the connecting line or connecting rope. When the second tray 3 passes the second turntable 10, the second turntable 10 rotates and then drives the positioning assembly 9 to unlock the rotation drive assembly 7. At the same time, since the limiting effect of the positioning assembly 9 on the rotation drive assembly 7 disappears, the guide block 81 slides in the second direction under the action of the gravity of the counterweight block 83, and then drives the rotation drive assembly 7 to descend along the inclined surface.

[0046] In order to drive the guide block 81 to slide, a second guide mechanism is provided on the first side of the frame 11. The second guide mechanism includes a second guide rail and a second slider. The second guide rail is fixed to the frame 11, and the second slider is fixed to the guide block 81. The second slider slides with the second guide rail to facilitate the directional movement of the guide block 81.

[0047] The rotation drive assembly 7 includes a second guide wheel 71, a connecting plate 72 and a baffle 73. The connecting plate 72 slides with the first side wall of the frame 11 to ensure that the rotation drive assembly 7 can make directional movement. One end of the connecting plate 72 is connected to the second guide wheel 71 to reduce the friction between the connecting plate 72 and the inclined surface, thereby facilitating the smooth lifting and lowering of the rotation drive assembly 7. The other end of the connecting plate 72 is connected to the baffle 73, and the second guide wheel 71 slides with the inclined surface. When the second pallet 3 passes through the rotation drive assembly 7, the baffle 73 abuts against the support plate of the second pallet 3. Under the blocking action of the baffle 73 and the movement drive of the second pallet 3 under the conveyor belt 12, the support plate of the second pallet 3 rotates around the positioning plate, so that the support plate of the second pallet 3 drives the assembly part of the workpiece to turn to the worker, which is convenient for the assembly of the workpiece.

[0048] In order to reduce the friction between the baffle 73 and the support plate of the second pallet 3, the baffle 73 is provided with a fifth guide wheel 74. When the second pallet 3 passes through the rotation drive assembly 7, the fifth guide wheel 74 abuts against the support plate of the second pallet 3, making the rotation of the support plate of the second pallet 3 smoother.

[0049] Among them, the connecting plate 72 slides with the first side wall of the frame 11 through a first guide mechanism. The first guide mechanism includes a first guide rail and a first slider. The first guide rail is fixed to the first side wall of the frame 11, and the first slider is fixed to the connecting plate. The first slider slides with the first guide rail.

[0050] The first turntable 82 includes a first rotating rod 822 and a first winding wheel 821 provided on the first rotating rod 822. The first rotating rod 822 is pivotally connected to another connecting tube on the second side wall of the frame 11. The first winding wheel 821 is connected to the guide block 81 by another connecting line or connecting rope. When the second tray 3 passes through the first turntable 82, the pin shaft 31 of the second tray 3 abuts against the first rotating rod 822 to drive the first rotating rod 822 to rotate, and then drive the first winding wheel 821 to wind up the connecting line or connecting rope. Under the pull of the connecting line or connecting rope, the guide block 81 slides along the first direction to prompt the rotation drive mechanism to slide to the highest position of the inclined surface.

[0051] The positioning assembly 9 is a spring latch, which includes a connecting pin 91, a sleeve 92 and a spring. The sleeve 92 is fixed to the first side wall of the frame 11, and the spring is arranged in the sleeve 92. The spring is used to provide an elastic force for the connecting pin 91 to extend along the sleeve 92. When the rotary drive assembly 7 rises into place, the connecting pin 91 locks the rotary drive assembly 7.

[0052] Specifically, the connecting plate 72 in the rotary drive assembly 7 has a slot 721. When the rotary drive assembly 7 is raised to its position, the connecting pin 91 is inserted into the slot 721 under the elastic force of the spring. Figure 5 When the connecting pin 91 is inserted into the slot 721, the connecting pin 91 is in a state of supporting the connecting plate 72, generating a resisting force on the connecting plate 72, thereby stably locking the connecting plate 72 and keeping the rotary drive assembly 7 at the highest position of the inclined surface. Figure 4 When the rotary drive assembly 7 is lowered into place, the connecting pin 91 disengages from the card slot 721, and the supporting effect on the connecting plate 72 disappears. Under the supporting effect of the connecting plate 72, the connecting pin 91 partially retracts into the sleeve 92. When in place, the connecting pin 91 has a limiting effect on the connecting plate 72, thereby ensuring that the second guide wheel 71 is located at the lowest position of the inclined surface and does not separate from the inclined surface.

[0053] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
