[0095] Combined with Figures 2 to 12 , the embodiment of the present invention provides an assembly system for assembling a rotating frame and a roller, including the following arranged in sequence:

[0096] A feeding device 1 for transporting a target roller 91.

[0097] A processing device arranged on a base 10, and the processing device includes:

[0098] A conveying structure 2 having a feeding station 21, an oiling station 22, and a press-fitting station 23, for sequentially transporting the target roller 91 from the feeding station 21 to the oiling station 22 and the press-fitting station 23.

[0099] A material pressing structure 3 arranged at the feeding station 21, for pressing the target roller 91 into the conveying structure 2 after the feeding device 1 transports the target roller 91 to the feeding station 21.

[0100] An oiling structure 4 arranged at the oiling station 22, for oiling the inner wall of the target roller 91 after the target roller 91 is transferred to the oiling station 22.

[0101] An assembly execution device 5, which is used to clamp the rotating frame 9 and, after the target roller 91 is transported to the press-fitting station 23, assemble the rotating frame 9 and the target roller 91;

[0102] A control device 6, which is electrically connected to the feeding device 1, the conveying structure 2, the pressing structure 3, the oiling structure 4, and the assembly execution device 5.

[0103] Combined Figure 2 with Figure 3 , in this embodiment, when the rotating frame 9 and the rollers 91 need to be assembled together, for example, 6 rollers 91 are assembled on the rotating frame 9, where 5 rollers 91 are of the same color (e.g., color A) and the remaining 1 roller 91 is of another color (e.g., color B); first, the rollers 91 are transported to the processing device by the feeding device 1. Specifically, the rollers 91 are transported to the incoming material station 21. At this time, the pressing structure 3 presses the rollers 91 into the conveying structure 2, and the conveying structure 2 transports the rollers 91 to the oiling structure 4 so that the oiling structure 4 can apply oil (grease) to the inner wall of the rollers 91. After the oiling is completed, the conveying structure 2 transports the rollers 91 to the press-fitting station 23. Then, the assembly execution device 5 takes out the rotating frame 9 from the placement box, aligns the corresponding mounting holes on the rollers 91 and the rotating frame 9, and presses the rotating frame 9 downward so that the rollers 91 are embedded into the mounting holes. By repeating the above steps 5 times in sequence, the assembly of 6 rollers 91 and the rotating frame 9 can be achieved. Through the assembly system of the present application, the assembly between the rotating frame 9 and the rollers 91 can be realized without manual operation, effectively improving the assembly efficiency of the rotating frame 9 and the rollers 91.

[0104] Combined Figure 3 with Figure 4 , in a specific embodiment, the assembly system of the present application for assembling the rotating frame and the rollers further includes a visual detection device 61 provided on the base 10, and the visual detection device 61 is electrically connected to the control device 6.

[0105] In this embodiment, since the mounting holes on the rotating frame 9 need to correspond to the positions of the rollers 91 in order to press the rollers 91 into the corresponding mounting holes, otherwise the rollers 91 will collide with the rotating frame 9 and be worn, so the present application is provided with a visual detection device 61. Among them, the visual detection device 61 of the present application is based on the CCD imaging principle and can locate the positions of the mounting holes of the rotating frame 9 placed on the visual detection device 61. If the positions of the mounting holes are offset, the visual detection device 61 controls the assembly execution device 5 to adjust the position of the rotating frame 9 through the control device 6, and then the assembly execution device 5 assembles the rotating frame 9 and the rollers 91.

[0106] Meanwhile, after the assembly of the roller 91 and the rotating frame 9 is completed, quality inspection can be carried out on the rotating frame 9 and the roller 91 placed on the vision inspection device 61. That is, it is determined whether the roller 91 is pressed into the corresponding mounting hole. If some rollers 91 have not completed the pressing operation, the vision inspection device 61 will control the assembly execution device 5 through the control device 6 to place the assembled rotating frame 9 and roller 91 into the defective product area. Otherwise, they will be placed in the non-defective product area. In this way, misjudgment situations caused by manual inspection are reduced. At the same time, the defective product inspection efficiency and inspection accuracy of the assembled workpieces are improved.

[0107] It should be noted that the control device 6 of the present application is a PLC controller. The control device 6 receives signals and controls the movement of the corresponding devices, thereby reducing manual operation.

[0108] Combined with Figure 2 and Figure 11 , in a specific embodiment, the assembly actuator includes:

[0109] A manipulator 51, the manipulator 51 is electrically connected to the control device 6;

[0110] A jaw cylinder 52, the jaw cylinder 52 includes:

[0111] A jaw cylinder body 53, the jaw cylinder body 53 is fixedly arranged on the manipulator 51;

[0112] A plurality of jaws 54, each of the jaws 54 is circumferentially arranged on the jaw cylinder body 53 and is respectively slidably connected to the jaw cylinder body 53. An installation space 541 is formed between the jaws 54. The lower ends of the jaws 54 are made of transparent materials. Among them, the jaw cylinder body 53 is used to drive all the jaws 54 to approach or move away from each other;

[0113] A vision detection component 55, the vision detection component 55 is arranged in the installation space 541 and is electrically connected to the control device 6, and is used to control the manipulator 51 to move to directly above the rotating frame 9;

[0114] A light source component 56, the light source component 56 is installed at the lower end of the jaw 54;

[0115] A focusing fiber optic sensor 57, the focusing fiber optic sensor 57 is installed at the lower end of the jaw 54 and is electrically connected to the control device 6.

[0116] In this embodiment, it should be noted that the manipulator 51 adopts the structure of the existing manipulator 51. As long as it can take out the rotating frame 9 from the placement area and transfer it to the vision inspection device 61, and realize the assembly of the roller 91 and the rotating frame 9, the present application will not elaborate too much.

[0117] In order to move the rotating frame 9, this application uses the jaw cylinder 52 to pick up and move the rotating frame 9. Specifically, this application is provided with 3 jaws 54. During manufacturing, according to actual needs, the number of jaws 54 can also be other, and this application does not make specific limitations; in this embodiment, the visual detection component 55 includes a CCD camera 551 and a lens 552. Among them, the CCD camera 551 can be fixedly arranged at the lower end of the jaw cylinder body 53 by bolting, and the lens 552 is assembled on the lower side of the CCD camera 551, that is, the visual detection component 55 shoots downward; the visual detection component 55 of this application is installed in the installation space 541, so that the visual detection component 55 does not affect the movement of all jaws 54, that is, it does not affect the picking up of the rotating frame 9.

[0118] When it is necessary to pick up the rotating frame 9, the manipulator 51 moves the jaw cylinder 52 above the unassembled rotating frame 9. The visual detection device 61 takes photo data of the rotating frame 9 and sends the photo data to the control device 6. The control device 6 obtains the position of the rotating frame 9 based on the received picture data, and the control device 6 drives the manipulator 51 to control the jaw cylinder 52 to move to a preset height directly above the rotating frame 9. Then, the jaw cylinder body 53 drives the 3 jaws 54 to move away from each other in a mutually distant direction, that is, the installation space 541 becomes larger. Then, the manipulator 51 controls the jaw cylinder 52 to descend to a preset position, and then controls the 3 jaws 54 to reset to clamp the rotating frame 9.

[0119] Among them, the jaw 54 of this application includes a connecting portion 542 and a clamping portion 543. The clamping portion 543 is fixedly arranged at the lower end of the connecting portion 542. The connecting portion 542 extends downward to the lower side of the lens 552. There is a space for the lens 552 to shoot between adjacent clamping portions 543, that is, the clamping portion 543 does not hinder the shooting of the visual detection component 55. In this embodiment, the light source component 56 includes but is not limited to an LED lamp. The light source component 56 is fixedly arranged on the upper side of the clamping portion 543 and illuminates downward. Since the clamping portion 543 is made of a transparent material, such as transparent plexiglass, the light can smoothly pass through the clamping portion 543 and shine downward, thereby supplementing light for the shooting of the visual detection device 61. Compared with the existing annular auxiliary light source that affects the opening and closing of the jaw cylinder 52 and has a large volume, 3 light source components 56 of this application are provided and are respectively fixedly arranged on the 3 clamping portions 543, so as not to affect the opening and closing of the jaw cylinder 52 and have a smaller volume.

[0120] In this embodiment, in order to improve the focusing accuracy of the visual detection device 61 for the rotating frame 9, a focusing fiber optic sensor 57 is fixedly arranged on one of the clamping portions 543 to determine the focusing position and improve the recognition rate of the visual detection component 55.

[0121] Combined with Figure 2 、 Figure 4 and Figure 5 In a specific embodiment, the feeding device 1 includes:

[0122] A vibrating hopper 11, the vibrating hopper 11 includes at least 2 storage areas 12 arranged at intervals, and each storage area 12 is used to store target rollers 91 of different colors respectively;

[0123] Vibratory bowls, there are at least 2 vibratory bowls, the vibratory bowls correspond to the storage areas 12 one by one, and each vibratory bowl is used to receive the target rollers 91 falling from the corresponding storage area 12 and to transfer the target rollers 91 to the output port of the vibratory bowl;

[0124] A connecting structure 14, the connecting structure 14 can be used to communicate with the output ports of all the vibratory bowls and transfer the target rollers 91 to the incoming material station 21.

[0125] In this embodiment, only 2 colors (such as color A and color B) of rollers 91 are installed on the rotating frame 9, so there are 2 storage areas 12 and 2 vibratory bowls are provided. For the convenience of description, the two vibratory bowls in this application are respectively named the first vibratory bowl 13 and the second vibratory bowl 131. The first vibratory bowl 13 is used to receive the rollers 91 of color A, and the second vibratory bowl 131 is used to receive the rollers 91 of color B.

[0126] In the actual assembly process, the rollers 91 of 2 different colors are respectively stored in the corresponding storage areas 12, and then the rollers 91 will respectively fall into the corresponding vibratory bowls. The rollers 91 are transported to the connecting structure 14 through the vibratory bowls. It should be understood that the rotating frame 9 of this application needs to be assembled with 5 rollers 91 of color A and 1 roller 91 of color B. Therefore, the connecting structure 14 is first connected to the first vibratory bowl 13. After 5 rollers 91 of color A are conveyed, it is then connected to the second vibratory bowl 131 to convey the last roller 91 of color B.

[0127] Combined with Figure 4 In a specific embodiment, the connecting structure 14 includes:

[0132] The straight vibration feeder 74 is transversely fixed on the base 10, and the feed port of the linear material channel 75 of the straight vibration feeder 74 is connected with the output port of the swing material channel 71, and the discharge port is connected with the incoming material station 21, so as to transfer the target roller 91 entering the linear material channel 75 to the incoming material station 21.

[0133] In this embodiment, the swing cylinder 7 and the direct vibration feeder 74 can be fixedly connected to the base 10 by bolting, wherein the connecting structure 101 includes a connecting rod 102 and a connecting plate 103, the lower end of the connecting rod 102 is fixed to the output end of the swing cylinder 7, the connecting plate 103 is coaxially fixed to the upper end of the connecting rod 102, and the upper side surface of the connecting plate 103 is inclined, the lower end of the swing channel 71 is in contact with and bolted to the upper side surface of the connecting plate 103, through such an installation method, the swing channel 71 can be stably supported.

[0134] In this embodiment, the blocking plate 72 is arranged horizontally and is connected to the swinging material channel 71 by bolting. It should be understood that the blocking plate 72 of the present application is provided with a through hole connected to the swinging material channel 71, so that the roller 91 can enter the swinging material channel 71 through the through hole, wherein the end face of the blocking plate 72 facing away from the swinging material channel 71 is arranged into an arc structure to increase the blocking effect of the blocking plate 72 on the roller 91.

[0135] In this embodiment, the counting fiber optic sensor 73 can be set on the blocking plate 72 or the swinging material channel 71 by bolting, and is used to count the number of rollers 91 entering the swinging material channel 71. Specifically, when five rollers 91 of color A enter the swinging material channel 71, the counting fiber optic sensor 73 controls the swinging cylinder 7 through the control device 6 to drive the swinging material channel 71 to rotate, so that the through hole of the blocking plate 72 is separated from the output port of the first vibration disk 13 and connected with the output port of the second vibration disk 131. At this time, the blocking plate 72 changes from blocking the output port of the second vibration disk 131 to blocking the output port of the first vibration disk 13. In this way, the transportation of rollers 91 of different colors is automatically realized.

[0136] In this embodiment, the linear chute 75 extends to the vicinity of the lower end of the swing chute 71, that is, there is a gap between the linear chute 75 and the lower end opening of the swing chute 71 to avoid interference between the swing chute 71 and the linear chute 75 when the swing chute 71 rotates. However, it should be understood that the roller 91 can smoothly slide into the linear chute 75 along the swing chute 71 under the action of gravity. After the roller 91 reaches the linear chute 75, the linear vibratory feeder 74 vibrates the roller 91 in the linear chute 75 to the incoming material station 21.

[0137] Combined with Figure 2 、 Figure 3 and Figure 8 , in a specific embodiment, the conveying structure 2 includes:

[0138] A driving motor 24, which is vertically fixed on the upper side of the base 10;

[0139] A rotating disk 25, which is coaxially and fixedly connected to the driving motor 24, and the incoming material station 21, the oiling station 22, and the press-fitting station 23 are respectively arranged at intervals on the rotating disk 25;

[0140] A clamping assembly 26, there are 3 clamping assemblies 26, and the 3 clamping assemblies 26 are respectively arranged at the incoming material station 21, the oiling station 22, and the press-fitting station 23, and each clamping assembly 26 is used to limit the target roller 91;

[0141] Each clamping assembly 26 includes:

[0142] A clamping base 27, which is fixed on the rotating disk 25;

[0143] Two symmetrically arranged clamping members 28, and each clamping member 28 respectively includes:

[0144] A clamping block 281, the upper end of the clamping block 281 is provided with a guiding inclined surface 283, and the clamping block 281 is slidably connected to the clamping base 27;

[0145] A spring 282, one end of the spring 282 is fixedly connected to the clamping base 27 and the other end is fixedly connected to the outside of the clamping block 281, and is used to drive the clamping block 281 to move closer to the other clamping block 281;

[0146] Among them, a clamping space 29 for the target roller 91 to be embedded is formed between the two clamping blocks 281.

[0147] In this embodiment, the drive motor 24 includes but is not limited to a servo motor. The drive motor 24 is fixedly connected to the base 10 by bolting. The rotating disk 25 is rotatably connected to the base 10 by a support 92. The drive motor 24 is started to drive the rotating disk 25 to rotate, thereby realizing the position change of each clamping component 26. At the same time, through rotation, the rollers 91 on the three workstations can all perform corresponding functions. For example, when one of the rollers 91 is entering the clamping space 29, the roller 91 of the adjacent clamping component 26 is being oiled, and the roller 91 of the other clamping component 26 is being assembled with the rotating frame 9, thereby effectively improving the assembly efficiency.

[0148] In this embodiment, the clamping base 27 can be fixedly mounted on the upper side of the rotating disk 25 by bolting, and the two clamping blocks 281 slide in the same direction. When the spring 282 is in a normal state, the distance between the two clamping blocks 281 is smaller than the outer diameter of the roller 91. That is, the roller 91 will first contact the guide inclined surfaces 283 of the two clamping blocks 281 under the downward pressure of the pressing structure 3, driving the two clamping blocks 281 away from each other. After the pressing operation of the pressing structure 3 is completed, the two springs 282 drive the clamping blocks 281 to move away from each other. 1 realizes the clamping of the roller 91. In this way, firstly, the roller 91 can be limited, so that the roller 91 and the clamping assembly 26 can be kept relatively fixed during the rotation of the rotating disk 25; secondly, when the oiling structure 4 oils the roller 91, since the grease itself is sticky, when there is an injection defect in the roller 91, the resistance between the clamping block 281 and the roller 91 is less than the stickiness of the grease, that is, the roller 91 will rise with the rise of the oiling structure 4, which is conducive to screening out unqualified rollers 91.

[0149] Combination Figure 2 , Figure 6 and Figure 7 In a specific embodiment, the pressing structure 3 includes:

[0150] A bracket 31, wherein the bracket 31 is fixedly mounted on the upper side of the base 10, and the bracket 31 is vertically provided with a clearance hole 311 for the target roller 91 to fall;

[0151] A spring ball plunger 32, wherein a plurality of spring ball plungers 32 are provided, and each spring ball plunger 32 is transversely arranged on the inner side wall of the clearance hole 311, and is used to prevent the target roller 91 entering the clearance hole 311 from sliding out;

[0152] The pressure wheel cylinder 33 is vertically fixed on the bracket 31 and is used to drive the probe of the spring ball plunger 32 to retract through the target roller 91 so that the target roller 91 falls into the clamping assembly 26.

[0153] In this embodiment, the bracket 31 includes a connected L-shaped portion 312 and a transverse portion 313. Among them, the L-shaped portion 312 is provided with a perforation 314 for the linear material channel 75 to pass through. After the linear material channel 75 passes through the perforation 314, it is placed on the upper side of the transverse portion 313. That is, the transverse portion 313 can support the linear material channel 75. In this embodiment, the relief hole 311 is provided in the transverse portion 313, and the free end of the linear material channel 75 is provided with a lower wheel hole communicating with the relief hole 311. The pressing wheel cylinder 33 is fixedly arranged at the upper end of the L-shaped portion 312. When the clamping assembly 26 is at the incoming material station 21, the piston rod of the pressing wheel cylinder 33, the lower wheel hole, the relief hole 311, and the clamping space 29 are on the same vertical extension line. It should be noted that the present application is symmetrically provided with 2 spring ball plungers 32. The probe of the spring ball plunger 32 extending into the relief hole 311 prevents the roller 91 from sliding out of the relief hole 311 without external force.

[0154] More preferably, the transverse portion 313 is fixedly provided with a roller position fiber optic sensor 34 facing the relief hole 311. The position of the roller position fiber optic sensor 34 is higher than that of the 2 spring ball plungers 32, and the roller position fiber optic sensor 34 is electrically connected to the pressing wheel cylinder 33. At the same time, in order to reduce the pressure loss of the piston rod of the pressing wheel cylinder 33 on the roller 91, a pressing block 35 is fixedly arranged at the lower end of the piston rod of the pressing wheel cylinder 33 to increase the contact area between the piston rod of the pressing wheel cylinder 33 and the roller 91. At the same time, the present application is fixedly provided with a pressing wheel position photoelectric sensor 36 on the L-shaped portion 312, which is electrically connected to the control device 6. The pressing wheel position photoelectric sensor 36 is electrically connected to the drive motor 24. After detecting that the clamping space 29 has a roller 91, the control device 6 is used to control the drive motor 24 to drive the rotating disk 25 to rotate 120 degrees, so that the clamping assembly 26 at the incoming material station 21 rotates to the oiling station 22.

[0155] During the actual assembly process, when the roller 91 slides to the blanking hole, it will enter the relief hole 311 through the blanking hole under its own gravity. Then, the lower side of the roller 91 will abut against the probe of the spring ball plunger 32. At this time, the roller position fiber optic sensor 34 controls the pressing wheel cylinder 33 to start through the control device 6. The pressing wheel cylinder 33 descends through the piston rod and the pressing block 35 in sequence into the lower wheel hole and the relief hole 311 until the pressing block 35 squeezes the roller 91 out of the relief hole 311 and into the clamping space 29. Then, the pressing wheel cylinder 33 and the spring ball plunger 32 reset.

[0156] Combined Figure 2 、 Figure 9 and Figure 10 , in a specific embodiment, the oiling structure 4 includes:

[0157] A slide cylinder 41, the slide cylinder 41 is vertically arranged on the upper side of the base 10;

[0160] An oiling nozzle 44, which is communicated with the metering valve 43 and is used for extending into the target roller 91 located at the oiling station 22 under the drive of the slide cylinder 41.

[0161] In this embodiment, the oil storage assembly 42 includes an oil storage tank in which grease is stored. Among them, the metering valve 43 oils the roller 91 through the oiling nozzle 44 under the action of compressed air. Among them, the metering valve 43 can adjust the amount of oil applied each time as needed; in this embodiment, in order to achieve uniform oiling on both inner sides of the roller 91, the oiling nozzle 44 of the present application is horizontally provided with 8 oil injection holes 45, and can oil the inner and outer walls of the inner ring of the roller 91 at the same time.

[0162] During the actual oiling process, the slide cylinder 41 drives the oil injection nozzle to extend into the inner ring of the roller 91, and then controls the grease to enter the preset position of the roller 91 through the metering valve 43. After the oiling operation is completed, the slide cylinder 41 resets. Due to the existence of the spring 282 and the clamping block 281, the roller 91 without injection molding defects will still stay in the clamping space 29, while the roller 91 with injection molding defects will rise with the reset of the slide cylinder 41. Therefore, an oiling position photoelectric sensor 46 and an alarm (not shown) are also fixedly arranged on the base 10 of the present application. The oiling position photoelectric sensor 46 and the alarm are both electrically connected to the control device 6. Among them, the alarm includes but is not limited to a buzzer or a warning light. When the oiling position photoelectric sensor 46 detects that a roller 91 is taken away from the oiling station 22 by the slide cylinder 41, the oiling position photoelectric sensor 46 controls the alarm to emit an alarm signal through the control device 6.

The manipulator 51 grasps the rotating frame 9, and after the assembly of the rotating frame 9 and the roller 91 is completed to form a workpiece, the workpiece is placed in the empty placement box. After all the rotating frames 9 in the placement box are installed with rollers 91, the right lifting cylinder 822 drives the four placement boxes to descend to vacate the upper right position.
