[0028] As a preferred embodiment of the present invention, a conveyor belt is installed on the inner side of the top of the support platform.

[0029] The beneficial effects of the present invention are:

[0030] 1. The present invention provides a positioning chamber, a cladding bracket and other structures, so that during installation, the outer tooth plate can be supported by the support plate, and the cladding bracket can be used to support the cladding, and then the components can be installed on the outer tooth plate. After the installation is completed, the lifting rod is driven to rise by the first electric telescopic cylinder, and then the cladding bracket is driven close to the support plate. Since the first guide rod and the U-shaped frame are provided, the lifting rod will drive the first guide rod to squeeze the U-shaped frame outward while rising, thereby pulling the support plate toward the outside of the positioning chamber, and the installed outer tooth plate falls into the cladding; the first electric telescopic cylinder works to drive the cladding bracket to descend, and the outer tooth plate and other components are compacted and fixed in the cladding through the pressing mechanism to achieve the purpose of assembly.

[0031] 2. The present invention sets convex teeth and one-way limiting tooth blocks. When the slide moves away from the positioning chamber, the one-way limiting tooth block will slide in the guide seat based on the inclined structure to avoid it. When the lifting rod descends, the one-way limiting tooth block will limit the convex teeth to prevent the support plate from resetting and interfering with the outer tooth plate.

[0032] 3. The present invention provides a shift plate and other structures. When the lifting rod is lowered to a certain height, the raised structure of the shift plate can be used to squeeze the roller to one side, so that the one-way limiting tooth block is separated from the convex teeth, and the contact has a limiting effect on the convex teeth, thereby realizing the reset of the slide plate and the support plate, and improving reliability.

[0033] 4. The present invention provides a pressing mechanism, which can press the annular frame downward based on the descent of the lifting rod, and then use the annular frame to press the extension arm downward. The extension arm is pressed, causing the pressing assembly to rotate on the mounting seat, and the rollers at the ends of the pressing arm move toward the center and press the components downward, so that they are reliably pressed into the shell, thereby improving practicality.

[0034] 5. The present invention provides a second guide rod, a fixing pin and a limit frame and other structures. When the lifting rod descends, the second guide rod is inserted into the connecting ring. Since the second guide rod is a Z-shaped structure, the fixing pin is separated from the side support plate. As the lifting rod continues to descend, the cladding bracket is limited by the limit frame, the first spring is compressed, and the lifting rod can continue to descend and then contact the extension arm of the annular frame to complete the subsequent pressing action. At this time, the position of the cladding bracket is fixed, the pressing distance can be better controlled, and the reliability is improved.

[0035] 6. The present invention is equipped with a pressure sensor assembly, which can monitor the pressure conditions of each roller. When a component is offset and cannot be stuck in the cladding, the numerical values ​​fed back by the pressure sensor assemblies of each cladding are quite different, thereby effectively determining an operational abnormality and controlling the alarm to sound an alarm.

[0045] Example 1:

[0046] An assembly device for the core components of an electric recliner for a car seat backrest, such as Figure 1-6 Shown, including:

[0047] A base 1, a positioning chamber 7 is fixed on the top of the base 1 through a first support frame 5, the bottom of the positioning chamber 7 is a cylindrical structure, and the top of the positioning chamber 7 is a trumpet-shaped structure;

[0048] The support plate 4 has one end slidably connected to the inner wall of the positioning chamber 7, and a slide plate 17 is fixed to the other end of the support plate 4. A connecting frame 19 is fixed to the top of the support plate 4, and the connecting frame 19 is connected to the outer wall of the positioning chamber 7 via a second spring 18;

[0049] The second support frame 13 is fixed on the base 1, a guide seat 21 is fixed on the top of the second support frame 13, and the slide 17 is slidably connected to the inner wall of the guide seat 21;

[0050] A first electric telescopic cylinder 2 is mounted on the base 1 via a bracket. A lifting rod 6 is fixed to the output end of the first electric telescopic cylinder 2. A first guide rod 20 is mounted on the side wall of the bottom end of the lifting rod 6. The bottom of the first guide rod 20 extends away from the positioning chamber 7. A U-shaped frame 16 is fixed to the outer wall of one side of the support plate 4. The U-shaped frame 16 is located in the moving path of the first guide rod 20. When the first guide rod 20 rises, it can pull the support plate 4 toward the outside of the positioning chamber 7.

[0051] The cladding bracket 8 has side support plates 36 fixed on both sides of the cladding bracket 8, and the side support plates 36 are installed on the lifting rod 6;

[0052] The pressing mechanism is installed on the outside of the cladding bracket 8;

[0053] By setting up structures such as the positioning chamber 7 and the cladding bracket 8, during installation, the support plate 4 can be used to support the outer tooth plate, and the cladding bracket 8 can be used to support the cladding, and then the components can be installed on the outer tooth plate. After the installation is completed, the first electric telescopic cylinder 2 drives the lifting rod 6 to rise, and then drives the cladding bracket 8 close to the support plate 4. Since the first guide rod 20 and the U-shaped frame 16 are set, the lifting rod 6 will drive the first guide rod 20 to squeeze the U-shaped frame 16 outward while rising, thereby pulling the support plate 4 to the outside of the positioning chamber 7, and the installed outer tooth plate falls into the cladding; the first electric telescopic cylinder 2 works to drive the cladding bracket 8 to descend, and the outer tooth plate and other components are compacted and fixed in the cladding through the pressing mechanism to achieve the purpose of assembly.

[0054] In order to avoid the support plate 4 interfering with the outer tooth plate during the descent process; Figure 2-5 As shown, the outer wall of one side of the slide plate 17 is provided with evenly distributed protruding teeth 23, and the inner wall of one side of the guide seat 21 is slidably connected to a one-way limiting tooth block 22 adapted to the protruding teeth 23. A movable frame 24 is fixed to one end of the one-way limiting tooth block 22, and the movable frame 24 is connected to the outer wall of one side of the guide seat 21 through a fourth spring 25; the protruding teeth 23 and the one-way limiting tooth block 22 cooperate to form a one-way limiting structure;

[0055] By setting the protruding teeth 23 and the one-way limiting tooth block 22, when the slide 17 moves in the direction away from the positioning chamber 7, the one-way limiting tooth block 22 will slide in the guide seat 21 based on the inclined structure to avoid it. When the lifting rod 6 descends, the one-way limiting tooth block 22 will limit the protruding teeth 23 to prevent the support plate 4 from resetting and interfering with the outer tooth plate.

[0056] In order to be able to control the pallet 4 to reset at the appropriate time; Figure 3 、 Figure 4 As shown, a shift plate 14 is fixed to the outer wall of one side of the lifting rod 6, and the top of the shift plate 14 is a structure that is raised in the direction away from the guide seat 21. A roller 15 is rotatably mounted on the outer wall of the movable frame 24, and the roller 15 is located on the moving path of the shift plate 14;

[0057] By providing structures such as the shift plate 14, when the lifting rod 6 is lowered to a certain height, the raised structure of the shift plate 14 can be used to squeeze the roller 15 to one side, so that the one-way limiting tooth block 22 disengages from the convex tooth 23 and contacts the limiting effect of the convex tooth 23, thereby realizing the reset of the slide plate 17 and the support plate 4, and improving reliability.

[0058] In order to facilitate the pressing of components into the cladding; Figure 5 As shown, the pressing mechanism includes:

[0059] The ring frame 9 has an extension arm on one side, and the extension arm is located below the lifting rod 6. The ring frame 9 is fixed to the base 1 by a third spring 10;

[0060] The mounting seat 26 has an annular seat 30 on one side thereof, and a pressing assembly is rotatably mounted on the mounting seat 26 via an axis. The pressing assemblies are circumferentially distributed on the base 1, and the axis of the pressing assembly is connected to the annular seat 30 via a flat spiral spring 31. The bottom end of the pressing assembly is located on the moving path of the annular frame 9.

[0061] In order to perform reliable pressing; Figure 5 As shown, the pressing assembly includes:

[0062] The pressure arm 28 is rotatably mounted on the mounting base 26 through a shaft. A roller 29 is mounted on one end of the pressure arm 28. The pressure arm 28 has a "7"-shaped structure.

[0063] An extension arm 32, one end of the extension arm 32 is fixed to the end of the pressure arm 28, and the other end of the extension arm 32 extends upward toward the center of the base 1, and the extension arm 32 is located below the annular frame 9;

[0064] By setting up a pressing mechanism, the annular frame 9 can be pressed downward based on the descent of the lifting rod 6, and the annular frame 9 is then used to press the extension arm 32 downward. The extension arm 32 is pressed, so that the pressing assembly rotates on the mounting seat 26, and the roller 29 at the end of the pressing arm 28 moves toward the center and presses the component downward, so that it is reliably pressed into the shell, thereby improving practicality.

[0065] To improve reliability; Figure 1 、 Figure 5 As shown, a limiting frame 27 is fixed to the top outer wall of the base 1, and the limiting frame 27 is located on the moving path of the cladding bracket 8;

[0066] The side support plate 36 is slidably connected to the inner wall of the lifting rod 6, and the side support plate 36 and the inner wall of the lifting rod 6 are connected by a first spring 37; a fixing pin 34 is installed on the outer wall of one side of the lifting rod 6 through a pin spring 33, and one end of the fixing pin 34 is slidably connected to the lifting rod 6, and a pin hole for inserting the fixing pin 34 is opened on one side of the side support plate 36;

[0067] A connecting ring 35 is fixed to the outer wall of one end of the fixing pin 34. A second guide rod 3 is fixed to the base 1.

Based on the descent of the lifting rod 6, the second guide rod 3 can squeeze the connecting ring 35 in the direction away from the lifting rod 6.

[0068] By setting up structures such as the second guide rod 3, the fixing pin 34 and the limit frame 27, when the lifting rod 6 descends, the second guide rod 3 is inserted into the connecting ring 35. Since the second guide rod 3 is a Z-shaped structure, the fixing pin 34 is separated from the side support plate 36. As the lifting rod 6 continues to descend, the shell bracket 8 is limited by the limit frame 27, the first spring 37 is compressed, and the lifting rod 6 can continue to descend and then contact the extension arm of the annular frame 9 to complete the subsequent pressing action. At this time, the position of the shell bracket 8 is fixed, which can better control the pressing distance and improve reliability.

[0069] To improve reliability; Figure 5 As shown, the roller 29 is equipped with a built-in pressure sensor assembly, which is used to detect the pressure when the roller 29 contacts the part;

[0070] The base 1 is provided with a control module, and the pressure sensor assembly and the control module realize signal transmission through wired or wireless means.

[0072] By setting up a pressure sensor assembly, the pressure conditions of each roller 29 can be monitored using the pressure sensor assembly. When the component is offset and cannot be stuck in the cladding, the numerical values ​​fed back by the pressure sensor assemblies of each cladding are quite different, so that the operation abnormality can be effectively determined and the alarm 11 can be controlled to sound an alarm.
