Description

Technical Field

[0001] This invention relates to the field of product manufacturing, specifically to a machine for assembling electronic limit switches for roller shutter doors. Background Technology

[0002] like Figure 1 , Figure 2 The electronic limit switch 1' for the roller shutter door is shown.

[0003] A first gear shaft hole 111' is provided on the bottom surface of the housing 11'. The input rotating component 12' passes through the first gear shaft hole 111'. The partition 123' in the middle of the input rotating component 12' is rotatably mounted at the position of the first gear shaft hole 111'. The external hook 121' at the bottom of the input rotating component 12' extends out of the first gear shaft hole 111' and is fixedly connected to the external gear 10' located outside the housing 11'. The first stage gear 122' at the top of the input rotating component 12' is located inside the housing 11'. A second gear shaft hole 112' and a third gear shaft hole 113' are also provided on the bottom surface of the housing 11'. The housing 11' has four vertical fixing blocks 114' with vertical fixing holes inside.

[0004] A second gear shaft 1121' is fixedly inserted into the second gear shaft hole 112', and a third gear shaft 1131' is fixedly inserted into the third gear shaft hole 113'.

[0005] A second-stage double gear 13' is rotatably mounted on the second gear shaft 1121'. The second-stage double gear 13' consists of a coaxial lower large gear 131' and an upper small gear 132'. Above the second-stage double gear 13', there is an output rotating component 15' rotatably mounted on the second gear shaft 1121'. The output rotating component 15' consists of a lower large gear 151' and an upper recess 152'. A magnet 16' is embedded in the recess 152'.

[0006] The third gear shaft 1131' is rotatably fitted with a third-stage double gear 14', which consists of a coaxial lower large gear 141' and an upper small gear 142'.

[0007] After assembly, the first-stage gear 122' on the input rotating component 12' meshes with the lower large gear 131' of the second-stage double gear 13', the upper small gear 132' of the second-stage double gear 13' meshes with the lower large gear 141' of the third-stage double gear 14', and the upper small gear 142' of the third-stage double gear 14' meshes with the lower large gear 151' of the output rotating component 15'.

[0008] A partition 17' is located in the middle of the housing 11'. The partition 17' has four vertical through-hole posts 1711'. The four vertical through-hole posts 1711' are located at the four vertices of a rectangle. There are two through-hole posts 1711' on each side of the partition 17'. The inner surface of the through-hole posts 1711' is an arc surface 1712'. Each through-hole post 1711' has a through hole 171'. The partition 17' is embedded and fixed inside the housing 11'. The aforementioned gear shaft and gear are located below the partition 17'.

[0009] The partition 17' has a through hole 172', and the position of the magnet 16' corresponds to the position of the through hole 172'.

[0010] A circuit board 18' is placed on the partition 17', and the socket 181' of the circuit board 18' extends out of the notch 115' on the housing 11'.

[0011] The upper opening of the housing 11' is covered by the rear cover 19', and ultrasonic heating is used to bond the housing 11' and the rear cover 19' together to form a roller shutter door electronic limiter 1'.

[0012] The housing 11', gear shaft, gear, and rear cover 19' are all plastic parts.

[0013] In actual use:

[0014] The movement of the roller shutter door is converted into the rotation of the external gear 10'. This rotation is transmitted through the external gear 10' fixed to the input rotating component 12', the first-stage gear 122' on the input rotating component 12', the lower large gear 131' of the second-stage double gear 13', the upper small gear 132' of the second-stage double gear 13', the lower large gear 141' of the third-stage double gear 14', the upper small gear 142' of the third-stage double gear 14', the lower large gear 151' of the output rotating component 15', and the magnet 16' embedded in the output rotating component 15'. This transmission chain ultimately converts the rotation of the magnet 16' into the rotation of the magnet 16'. The circuit board 18' senses the rotation angle of the magnet 16', and the converted electrical signal is transmitted to the external processor through the line connected to the socket 181'. This allows the processor to determine the rotation position of the roller shutter door and control the roller shutter door motor in real time.

[0015] During the manufacturing process of the aforementioned electronic limit switch 1' for roller shutter doors:

[0016] Currently, manual assembly line operations are used, which are inefficient and result in inconsistent quality. Summary of the Invention

[0096] To more clearly illustrate the technical solution of the present invention, the accompanying drawings used in the description will be briefly introduced below. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For those skilled in the art, other embodiments can be obtained based on these drawings without creative effort.

[0097] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown:

[0098] The assembly workbench 100 is mounted on the frame 1. The assembly workbench 100 is a disc covered inside the machine housing 101. Its rotating shaft is driven by a motor and can rotate in steps (the rotating shaft and motor are not shown in the figure, which is the prior art). The motor is connected to and controlled by the controller.

[0099] The assembly workbench 100 is divided into 12 stations, namely stations A, B, C, D, E, F, G, H, I, J, K, and L. Each station has a recess composed of limit blocks 106 to accommodate the housing 11'. Each station performs the following steps:

[0100] Station A: The empty shell 11' is sent from the conveyor belt and falls into the recess of the assembly workbench 100;

[0101] Station B: The third gear shaft 1131' is fed from the transmission belt, clamped by the grippers, and inserted into the third gear shaft hole 113'.

[0102] Station C: The second gear shaft 1121' is fed from the transmission belt, clamped by the grippers, and inserted into the second gear shaft hole 112'.

[0103] Station D: Input rotating component 12' is fed from the transmission belt, clamped by the grippers, and inserted into the first gear shaft hole 111';

[0104] Station E: The second-stage double gear 13' is delivered from the conveyor belt, clamped by the grippers, and inserted into the second gear shaft 1121'. The large gear 131' below the second-stage double gear 13' meshes with the first-stage gear 122' on the input rotating component 12'.

[0105] Station F: The third-stage double gear 14' is delivered from the conveyor belt, clamped by the grippers, and inserted into the third gear shaft 1131'. The large gear 141' below the third-stage double gear 14' meshes with the small gear 132' above the second-stage double gear 13'.

[0106] G station: Inject lubricating oil into the small gear 142' above the first-stage gear 122', large gear 131', small gear 132', large gear 141', and the third-stage double gear 14' to reduce gear wear and improve equipment stability;

[0107] Station H: The output rotating component 15' is sent from the conveyor belt, and a magnet 16' is embedded in the recess 152' of the output rotating component 15'. The output rotating component 15' is clamped by a gripper and inserted into the second gear shaft 1121'. The large gear 151' below the output rotating component 15' meshes with the small gear 142' above the third-stage double gear 14'.

[0108] Station I: The plastic partition 17' is conveyed from the conveyor belt, clamped by outward-expanding grippers, and transported to the position. The pressure head presses down into the housing 11', and the magnet 16' embedded in the recess 152' of the output rotating part 15' is exposed through the through hole 172' on the partition 17'.

[0109] J station: Circuit board 18' is sent from the conveyor belt, suction cup picks up circuit board 18' and moves it onto housing 11' and puts it on partition 17';

[0110] K station: The suction cup picks up the back cover 19', moves it onto the housing 11', and places it on the housing 11';

[0111] Station L: Ultrasonic heating, the back cover 19' and the shell 11' are bonded together to obtain the finished product.

[0112] The finished product obtained above is sent out. Select the external gear 10' for different application scenarios. In addition, operate to fix the external hook 121' extending from the first gear shaft hole 111' at the lower part of the input rotating part 12' to the external gear 10' located outside the housing 11'.

[0113] Among them: G and L stations have no feeding operation, so there is no conveyor belt and hopper; A, B, C, D, E, F, H, I, K stations are all equipped with vibrating hoppers 102. The vibrating hoppers 102 vibrate the parts and arrange them sequentially on the conveyor belt 103 to be transported to the station (here, conveyor belt 103 is a general term, and the structure of the conveyor belt 103 is different for each station due to the different parts being transported, and the vibrating hopper is existing technology); J station uses a tray 104 because the circuit board 18' is not suitable for vibration. The circuit board 18' is arranged in the tray 104 and is sucked onto the conveyor belt 103 by the suction cups 105 that move on the slide rail.

[0114] Specific structure:

[0115] Station A: The empty shell 11' is sent from the conveyor belt and falls into the recess of the assembly workbench 100;

[0116] like Figure 7 shown

[0117] The frame 1 is equipped with a belt conveyor 2A (the belt conveyor 2A is the conveyor belt 103 mentioned above, and the same applies to each workstation below), and the housings 11' of the electronic limiters are arranged sequentially on the belt conveyor 2A.

[0118] The housing 11' inside the belt conveyor 2A is pushed toward the assembly workbench 100 (not shown in the figure; the side of the frame 1 is the assembly workbench 100, which has a recess composed of limit blocks 106 to accommodate the housing 11').

[0119] A stop block 21A with a blocking housing 11' is provided on the frame 1 at the end of the belt conveyor 2A.

[0120] A cylinder 47A fixed on the frame 1 is connected to and drives a horizontal moving plate 45A to move horizontally. A vertical sliding groove 44A is provided on the horizontal moving plate 45A. A vertical moving plate 42A is moved and embedded in the vertical sliding groove 44A. A cylinder 43A fixed on the horizontal moving plate 45A is connected to and drives the vertical moving plate 42A to move vertically in the vertical sliding groove 44A. A gripper 4A is installed on the vertical moving plate 42A. The gripper 4A is composed of two claw plates 48A. A gripper cylinder 41A installed on the vertical moving plate 42A is connected to and drives the gripper 4A to open and close.

[0121] The cylinders and grippers mentioned above are connected to and controlled by the controller.

[0122] In actual work:

[0123] The first housing 11' on the belt conveyor 2A is blocked at the position of the stop block 21A.

[0124] At this time, gripper 4A is open.

[0125] Cylinder 43A drives vertical moving plate 42A to move vertically downward in vertical slide 44A until the two claws 48A of gripper 4A are located on both sides of housing 11'.

[0126] Then the gripper cylinder 41A drives the gripper 4A to open, and each claw 48A moves inward to grasp the housing 11';

[0127] Then, cylinder 4A3 drives vertical moving plate 42A to move vertically upward in vertical slide 44A, and gripper 4A lifts housing 11'.

[0128] Then the cylinder 47A drives the transverse moving plate 45A to move laterally toward the assembly worktable 100 until it moves above the recess formed by the limit block 106 already on the assembly worktable 100.

[0129] Then, cylinder 43A drives vertical moving plate 42A to move vertically downward in vertical slide 44A, placing housing 11' into the recess;

[0130] Then the gripper cylinder 41A drives the gripper 4A to open and release the housing 11';

[0131] Then, cylinder 43A drives vertical moving plate 42A to move vertically upward in vertical slide 44A to the uppermost position;

[0132] Then, cylinder 47A drives the transverse moving plate 45A to move laterally back to its original position;

[0133] After one housing 11' is lifted away by the gripper 4A, the next housing 11' is pushed by the belt conveyor 2A and blocked by the stop block 21A, until the next cycle operation.

[0134] By repeating the above actions, the housing 11' can be automatically placed into the recess formed by the limiting blocks 106 on the assembly workbench 100.

[0135] Station B: The third gear shaft 1131' is fed from the transmission belt, clamped by the grippers, and inserted into the third gear shaft hole 113'.

[0136] like Figure 8 , Figure 9 As shown:

[0137] The following is a description of the structure of station B: cylindrical pin 5B is equivalent to the third gear shaft 1131', and the shaft hole into which cylindrical pin 5 is inserted is equivalent to the third gear shaft hole 113'.

[0138] A horizontally placed rotary cylinder 31B is provided on the frame 1. A horizontally placed transition shaft 3B is installed on the cylinder shaft of the rotary cylinder 31B. A radial cylindrical pin receiving hole 30B is opened on the outer wall of the transition shaft 3B. The length of the cylindrical pin receiving hole 30B is shorter than that of the cylindrical pin 5B, and the diameter is slightly larger than that of the cylindrical pin 5B, so that the cylindrical pin 5B can be inserted into it and the upper part is exposed.

[0139] The frame 1 is equipped with a gripper drive mechanism.

[0140] The gripper drive mechanism is as follows:

[0141] A cylinder 47B fixed on the frame 1B is connected to a connector 46B. The connector 46B connects to and drives a transverse moving plate 45B to move laterally. A vertical sliding groove 44B is formed on the transverse moving plate 45B. A vertical moving plate 42B is movably embedded in the vertical sliding groove 44B. A cylinder 43B fixed on the transverse moving plate 45B connects to and drives the vertical moving plate 42B to move vertically in the vertical sliding groove 44B. A gripper 4B is installed on the vertical moving plate 42B. A gripper cylinder 41B installed on the vertical moving plate 42B connects to and drives the gripper 4B to open and close. The gripper 4B consists of two claw plates 48B. Each opposing claw plate 48B has an arc-shaped vertical groove 40B. Thus, when the two claw plates 48B of the gripper 4B are closed, the arc-shaped vertical groove 40B can firmly clamp the cylindrical pin 5B.

[0142] When the aforementioned transition shaft 3B rotates to the point where the cylindrical pin receiving hole 30B is vertical, the vertical space after the two arc-shaped vertical grooves 40B of the gripper 4B are closed is located directly above the cylindrical pin receiving hole 30B.

[0143] The frame 1 is also equipped with a cylindrical pin conveyor belt 2B, in which cylindrical pins 5B are pushed toward the assembly workbench 100 (not shown in the figure; the side of the frame 1 is the assembly workbench 100, on which the conveyed housing 11' is placed).

[0144] The rear end 21B of the cylindrical pin conveyor belt 2B is connected to the vibrating hopper 102 (not shown in the figure), which outputs the cylindrical pins 5B placed inside to the cylindrical pin conveyor belt 2B one by one through vibration.

[0145] When the aforementioned transition shaft 3B rotates to the point where the cylindrical pin receiving hole 30B faces the cylindrical pin conveyor belt 2B and is horizontal, the front end 22B of the cylindrical pin conveyor belt 2B corresponds to the cylindrical pin receiving hole 30B.

[0146] All of the above rotary cylinders 31B, 47B, 43B, and gripper cylinder 41B are connected to and controlled by the controller to coordinate the actions of the workflow.

[0147] In actual work:

[0148] The rotary cylinder 31B drives the transition shaft 3B to rotate so that the cylindrical pin receiving hole 30B faces the cylindrical pin conveyor belt 2B and is horizontal. The cylindrical pin 5B enters the cylindrical pin receiving hole 30B from the front end 22B of the cylindrical pin conveyor belt 2B (the vibrating hopper connected to the rear end 21B of the cylindrical pin conveyor belt 2B continuously pushes the cylindrical pin 5B into the cylindrical pin conveyor belt 2B one by one).

[0149] Then, the rotary cylinder 31B drives the transition shaft 3B to rotate until the cylindrical pin receiving hole 30B is vertical. At this time, the cylindrical pin receiving hole 30B and the cylindrical pin 5B inside it are directly below the gripper 4B.

[0150] At this time, gripper 4B is open.

[0151] Cylinder 43B drives vertical moving plate 42B to move vertically downward in vertical slide 44B until the two claws 48B of gripper 4B are located on both sides of the part of cylindrical pin 5B that is exposed in cylindrical pin receiving hole 30B.

[0152] Then the gripper cylinder 41B drives the gripper 4B to close and clamp the cylindrical pin 5B;

[0153] Then the cylinder 43B drives the vertical moving plate 42B to move vertically upward in the vertical slide 44B until the gripper 4B pulls the cylindrical pin 5B out of the cylindrical pin receiving hole 30B.

[0154] Then the cylinder 47B is connected via the connector 46B and drives the transverse moving plate 45B to move laterally toward the assembly worktable 100 until it moves above the housing 11' already on the assembly worktable 100 and above the shaft hole to be inserted.

[0155] Then the cylinder 43B drives the vertical moving plate 42B to move vertically downward in the vertical slide 44B until the cylindrical pin 5B clamped by the chuck 4B is inserted into the shaft hole.

[0156] Then the gripper cylinder 41B drives the gripper 4B to separate and release the cylindrical pin 5B;

[0157] Then, cylinder 43B drives vertical moving plate 42B to move vertically upward in vertical slide 44B to the uppermost position;

[0158] Then, cylinder 47B is connected via connector 46B and drives transverse moving plate 45B to move laterally back to its original position.

[0159] The rotary cylinder 31B drives the transition shaft 3B to rotate to the cylindrical pin receiving hole 30B facing the cylindrical pin conveyor belt 2B and horizontal. The next cylindrical pin 5B enters the cylindrical pin receiving hole 30B from the front end 22B of the cylindrical pin conveyor belt 2B.

[0160] By repeating the above actions, the cylindrical pin 5B can be automatically inserted into the shaft hole from a horizontal position to a vertical position.

[0161] The above structure, through the cooperation of a rotating transition shaft, conveyor belt, and grippers, allows the transverse cylindrical pins to be changed to a vertical orientation, and then gripped by the grippers to be installed in the housing position. This achieves an automated operation process in which cylindrical pins are picked up, positioned, and installed one by one without manual operation.

[0162] Station C: The second gear shaft 1121' is fed from the transmission belt, clamped by the grippers, and inserted into the second gear shaft hole 112'.

[0163] like Figure 8 , Figure 9 As shown:

[0164] The structure of station C is the same as that of station B, and will not be described again. In the description of station B, the cylindrical pin 5B is equivalent to the second gear shaft 1121', and the shaft hole into which the cylindrical pin 5 is inserted is equivalent to the second gear shaft hole 112'.

[0165] Station D: Input rotating component 12' is fed from the transmission belt, clamped by the grippers, and inserted into the first gear shaft hole 111';

[0166] like Figure 10 As shown:

[0167] like Figure 3 , Figure 4 , Figure 5 As shown:

[0168] The frame 1 is equipped with a belt conveyor 2D, and the transmission components 12' of the electronic limiters are arranged sequentially on the belt conveyor 2D.

[0169] The transmission component 12' inside the belt conveyor 2D is pushed toward the assembly workbench 100 (not shown in the figure; the side of the frame 1 is the assembly workbench 100, on which the conveyed housing 11' is placed).

[0170] A stop 21D for blocking transmission component 12' is provided on the frame 1 at the end of the belt conveyor 2D.

[0171] A cylinder 47D fixed on the frame 1 is connected to a connector 46D. The connector 46D is connected to and drives a horizontal moving plate 45D to move horizontally. A vertical sliding groove 44D is provided on the horizontal moving plate 45D. A vertical moving plate 42D is moved and embedded in the vertical sliding groove 44D. A cylinder 43D fixed on the horizontal moving plate 45D is connected to and drives a vertical moving plate 42D to move vertically in the vertical sliding groove 44D. A gripper 4D is installed on the vertical moving plate 42D. A gripper cylinder 41D installed on the vertical moving plate 42D is connected to and drives the gripper 4D to open and close.

[0172] The gripper 4D consists of two gripper plates, each 48D.

[0173] In actual work:

[0174] The first drive component 12' on the belt conveyor 2D is stopped at the position of the stop block 21D.

[0175] At this time, the gripper 4D is open.

[0176] The cylinder 43D drives the vertical moving plate 42D to move vertically downward in the vertical slide 44D until the two claws 48D of the gripper 4D are located on both sides of the transmission member 12'.

[0177] Then the gripper cylinder 41D drives the gripper 4D to close, and each gripper piece 48 moves inward to grasp the transmission component 12';

[0178] Then, cylinder 43D drives vertical moving plate 42D to move vertically upward in vertical slide 44D, and gripper 4D lifts transmission component 12'.

[0179] Then the cylinder 47D is connected via the connector 46D and drives the transverse moving plate 45D to move laterally toward the assembly worktable 100 until it moves above the first gear shaft hole 111' of the housing 11' already on the assembly worktable 100.

[0180] Then, cylinder 43D drives vertical moving plate 42D to move vertically downward in vertical slide groove 44D, inserting transmission component 12' into first gear shaft hole 111';

[0181] Then the gripper cylinder 41D drives the gripper 4D to open and release the transmission component 12';

[0182] Then, cylinder 43D drives vertical moving plate 42D to move vertically upward in vertical slide 44D to the uppermost position;

[0183] Then, cylinder 47D is connected via connector 46D and drives transverse moving plate 45D to move laterally back to its original position.

[0184] After one transmission component 12' is lifted away by the gripper 4D, the next transmission component 12' is pushed by the belt conveyor 2D and blocked by the stop block 21D, until the next cycle operation.

[0185] By repeating the above actions, the automated operation of inserting the transmission component 12' into the first gear shaft hole 111' can be achieved.

[0186] Station E: The second-stage double gear 13' is delivered from the conveyor belt, clamped by the grippers, and inserted into the second gear shaft 1121'. The large gear 131' below the second-stage double gear 13' meshes with the first-stage gear 122' on the input rotating component 12'.

[0187] like Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 As shown:

[0188] The following is a description of workstation E:

[0189] Gear 8E is equivalent to the second-stage double gear 13', the lower large gear 88E is equivalent to the lower large gear 131' of the second-stage double gear 13', the axle 92E is equivalent to the second gear shaft 1121', and the gear 9E installed first is equivalent to the first-stage gear 122' on the input rotating part 12'.

[0190] Figure 16 The first vertical fixing frame horizontal plate 4E and the second vertical fixing frame horizontal plate 5E are missing.

[0191] In this invention, a cylinder 21E is installed at the top of the frame 1. The cylinder 21E is connected to and drives the transverse fixed frame 3E to move laterally through the cylinder transmission mechanism 22E. The cylinder 23E fixed on the transverse fixed frame 3E is connected to and drives the first vertical fixed frame 4E to move vertically. The first vertical fixed frame 4E is slidably embedded in the slide rail (not shown in the figure) fixed on the transverse fixed frame 3E.

[0192] The second vertical fixing frame 5E is slidably embedded in the slide rail 40E fixed on the first vertical fixing frame 4E.

[0193] The first vertical fixing frame 4E extends laterally from the first vertical fixing frame horizontal plate 41E, and the second vertical fixing frame 5E extends laterally from the second vertical fixing frame horizontal plate 51E.

[0194] A through hole 42E is provided on the first vertical fixing frame horizontal plate 41E. A hollow sleeve 43E coaxial with the through hole 42E is fixedly connected to the lower surface of the first vertical fixing frame horizontal plate 4E. A slanted through groove 44E is provided on the side wall of the sleeve 43E, with one end of the slanted through groove 44E being higher than the other end.

[0195] A bearing 53E is fixedly installed inside the through hole 52E on the horizontal plate 51E of the second vertical fixing frame.

[0196] A three-tiered vertical shaft 6E, consisting of a large-diameter section 61E, a medium-diameter section 62E, and a small-diameter section 63E, passes through a bearing 6E and rotatably passes through a sleeve 43E and a through hole 42E.

[0197] The middle diameter portion 62E of the vertical shaft 6E mates with the inner ring of the bearing 53E. The clamps 622E, which are located on the top surface of the large diameter portion 61E and in the annular groove 621E on the middle diameter portion 62E, are positioned below and above the inner ring of the bearing 53E, respectively, thus clamping the bearing 53E.

[0198] A screw 623E, acting as a pin, passes through the oblique groove 44E and is screwed into a screw hole 620E opened on the middle diameter portion 62E, thus being fixed to the vertical shaft 6E. The screw 623E can slide in the oblique groove 44E.

[0199] A lower spring 71E is fitted on the small diameter portion 63E. The lower spring 71E is located inside the sleeve 43E. The lower end of the lower spring 71E abuts against the top surface of the middle diameter portion 62E, and the upper end of the lower spring 71E abuts against the lower surface of the first vertical fixing frame horizontal plate 41E.

[0200] The upper spring 72E is sleeved on the small diameter part 63E. The threaded part at the top of the small diameter part 63E is fitted with a washer 64E and a preload nut 65E is screwed on. The lower end of the upper spring 72E abuts against the upper surface 41E of the first vertical fixing frame horizontal plate, and the upper end of the upper spring 72E abuts against the lower surface of the washer 64E.

[0201] The bottom end of the large diameter part 61E of the vertical shaft 6E is fixedly connected to a three-jaw positioning and gripping block mechanism 69E. The three-jaw positioning and gripping block mechanism 69E is existing technology. The three jaws can open and close to grip the cylinder.

[0202] Thus, at the initial position, the lower spring 71E abuts against the middle diameter portion 62E of the vertical shaft 6E, pressing the vertical shaft 6E downwards. The screw 623E presses against the lowest end of the inclined through groove 44E. The upper spring 72E is pre-tightened by the pre-tightening nut 65E, pressing against the washer 64E and providing support, preventing the entire vertical shaft 6E from falling down.

[0203] The frame 1 is also equipped with a gear conveyor belt 81E, and the gear 8E in the gear conveyor belt 81E is pushed towards the assembly worktable 100 by the pushing mechanism.

[0204] A cylinder 82E is also fixed on the frame 1. The cylinder 82E pushes the gear conveyor block 83E to move horizontally on the slide rail 85E on the frame 1. The direction of movement is perpendicular to the gear conveyor belt 81E. There is a gear receiving groove 84E on the gear conveyor block 83E.

[0205] To the side of the frame is the assembly workbench 100, on which is the conveyed housing 11', and a gear 9E has already been installed inside the housing 11'.

[0206] The installed gear 9E and the gear 8E conveyed on the gear conveyor belt can respectively correspond to: the first-stage gear 122' and the lower large gear 131' of the second-stage double gear 13' on the input rotating member 12'; or, the upper small gear 132' of the second-stage double gear 13' and the lower large gear 141' of the third-stage double gear 14'; or, the upper small gear 142' of the third-stage double gear 14' and the lower large gear 151' of the output rotating member 15'.

[0207] It can operate according to the set program, or several sensors can be installed on the frame 1 to sense the moving distance of the horizontal fixed frame 3E, the first vertical fixed frame 4E, the second vertical fixed frame 5E, and the gear conveying block 83E, and send the data to the processor. The processor then controls the cylinders that drive these components, thereby controlling the movement of these components.

[0208] During work:

[0209] Cylinder 82E pushes gear conveyor block 83E to move horizontally on slide rail 85E on frame 1. Gear receiving groove 84E is aligned with the output end of gear conveyor belt 81E. One gear 8E is pushed into gear receiving groove 84E. Cylinder 82E then pushes gear conveyor block 83E to move horizontally on slide rail 85E on frame 1 in the opposite direction. Gear 8E is sent directly below three-jaw positioning gripping block mechanism 69E. Other gears 8E on gear conveyor belt 81E wait for the next push.

[0210] Gear 8E comes in two forms, one of which is as follows: Figure 11 , Figure 12 As shown, there is a double gear, with a large gear 88E at the bottom and a cylindrical protrusion 86E at the top of the small gear 87E. Another type is a single gear, with a cylindrical protrusion above the gear. A magnet is embedded in the groove of the cylindrical protrusion. In either case, there is a cylindrical protrusion for the three-jaw positioning gripping block mechanism to grip.

[0211] At this initial working position, the cylinder 23E fixed on the horizontal fixed frame 3E drives the first vertical fixed frame 4E to move vertically downward, so that the second vertical fixed frame 5E, the vertical shaft 6E, and the three-jaw positioning and gripping block mechanism 69E move downward together. At this time, the three claws of the three-jaw positioning and gripping block mechanism 69E are open.

[0212] After the three-jaw chuck reaches the cylindrical protrusion 86E of the gear 8E, the first vertical fixing frame 4E, the second vertical fixing frame 5E, the vertical shaft 6E, and the three-jaw positioning and gripping block mechanism 69E stop moving downwards, and the three jaws of the three-jaw positioning and gripping block mechanism 69E close together to grip the cylindrical protrusion 86E of the gear 8E.

[0213] The cylinder 23E fixed on the horizontal fixed frame 3E drives the first vertical fixed frame 4E to move vertically upward. In this way, together with the second vertical fixed frame 5E, the vertical shaft 6E, and the three-jaw positioning and gripping block mechanism 69E, the gear 8E is gripped and leaves the gear receiving groove 84E.

[0214] After the gear 8E moves upward to the preset suitable position, that is, after the gear 8E disengages from the gear receiving groove 84E, the first vertical fixing frame 4E, the second vertical fixing frame 5E, the vertical shaft 6E, the three-jaw positioning and gripping block mechanism 69E, and the gear 8E stop moving upward. The cylinder 21E is connected through the cylinder transmission mechanism 22E and drives the horizontal fixing frame 3E to move horizontally outward. Together with the first vertical fixing frame 4E, the second vertical fixing frame 5E, the vertical shaft 6E, the three-jaw positioning and gripping block mechanism 69E, and the gear 8E, they move horizontally outward until the gear 8E reaches above the gear shaft 92E inside the housing 91E to be installed.

[0215] Then, the cylinder 23E fixed on the horizontal fixed frame 3E drives the first vertical fixed frame 4E to move vertically downward, so that the second vertical fixed frame 5E, the vertical shaft 6E, the three-jaw positioning and gripping block mechanism 69E, and the gear 8E move downward together.

[0216] The first scenario is:

[0217] The shaft hole of gear 8E is smoothly inserted into gear shaft 92E. Gear 8E meshes smoothly with the previously installed gear 9E, with no interference or jamming. After gear 8E is in place, the first vertical fixing frame 4E, the second vertical fixing frame 5E, the vertical shaft 6E, and the three-jaw positioning and gripping block mechanism 69E stop moving downwards. The three jaws of the three-jaw positioning and gripping block mechanism 69E open and release gear 8E. The first vertical fixing frame 4E, the second vertical fixing frame 5E, the vertical shaft 6E, and the three-jaw positioning and gripping block mechanism 69E move upwards together. After reaching the position, cylinder 21E is connected to and drives the transverse fixing frame 3E to move laterally inwards through cylinder transmission mechanism 22E. Together with the first vertical fixing frame 4E, the second vertical fixing frame 5E, the vertical shaft 6E, and the three-jaw positioning and gripping block mechanism 69E, they move laterally inwards back to the initial working position.

[0218] The second scenario is:

[0219] The shaft hole of gear 8E is inserted into gear shaft 92E. Gear 8E interferes with the previously installed gear 9E, that is, the lower surface of gear 8E presses against the upper surface of the previously installed gear 9E and gets stuck.

[0220] At this point, the first vertical fixing frame 4E continues to descend; since the middle diameter portion 62E of the vertical shaft 6E engages with the inner ring of the bearing 53E, the vertical shaft 6E can rotate; and the second vertical fixing frame 5E can move relative to the first vertical fixing frame 4E along the slide rail 40E; and the screw 623E fixed on the vertical shaft 6E can move upward within the oblique through groove 44E on the side wall of the sleeve 43E, thus playing a driving, guiding, and limiting role; and since the vertical shaft 6E can push upward to compress the lower spring 71E; therefore, the vertical shaft 6E and the second vertical fixing frame 5E can remain vertically stationary while the first vertical fixing frame 4E descends; simultaneously, the vertical shaft 6E is driven to rotate by the engaging structure of the screw 623E and the oblique through groove 44E, causing the gear 8E at its lower end to rotate, and the relative position of the teeth of the gear 8E and the previously installed gear 9E changes. Finally, the teeth of the gear 8E rotate to the meshing position with the previously installed gear 9E. At this point, the gear 8E loses the support of the gear 9E below. When the lower spring 71E returns to its original position, the vertical shaft 6E pops downward, and the gear 8E pops downward until it engages with the previously installed gear 9E. During this process, the screw 623E fixed on the vertical shaft 6E moves from top to bottom in the oblique through groove 44E and returns to the bottom. The gear 8E rotates together with the gear 9E, but since the gears 8E and 9E are already engaged, there will be no interference, and the gear 8E can be installed smoothly.

[0221] After gear 8E is in position, the first vertical fixing frame 4E, the second vertical fixing frame 5E, the vertical shaft 6E, and the three-jaw positioning and gripping block mechanism 69E stop moving downwards. The three jaws of the three-jaw positioning and gripping block mechanism 69E open and close the gear 8E. The first vertical fixing frame 4E, the second vertical fixing frame 5E, the vertical shaft 6E, and the three-jaw positioning and gripping block mechanism 69E move upwards together. After they are in position, cylinder 21E is connected to and drives the transverse fixing frame 3E to move laterally inwards through cylinder transmission mechanism 22E. Together with the first vertical fixing frame 4E, the second vertical fixing frame 5E, the vertical shaft 6E, and the three-jaw positioning and gripping block mechanism 69E, they move laterally inwards to return to the initial working position.

[0222] The E-station structure is mainly designed to solve the second situation, allowing gear 8E to rotate to the meshing position on its own under interference without prior manual marking.

[0223] The E-station structure utilizes the rotational motion during gear installation to enable the subsequently installed gear to self-position, avoiding interference with the teeth of the previously installed gear. There is no jamming between the gears, ensuring perfect meshing and automated gear assembly. The rotation angle meets the gear meshing requirements, making it more convenient than marking, saving marking time, and thus shortening the gear rotation and positioning time. Furthermore, the entire process can be automated without skilled operators.

[0224] Station F: The third-stage double gear 14' is delivered from the conveyor belt, clamped by the grippers, and inserted into the third gear shaft 1131'. The large gear 141' below the third-stage double gear 14' meshes with the small gear 132' above the second-stage double gear 13'.

[0225] like Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 As shown:

[0226] The structure of station F is the same as that of station E, and will not be described again. In the description of station E, gear 8E is equivalent to the third-stage double gear 14', the lower large gear 88E is equivalent to the lower large gear 141' of the third-stage double gear 14', the axle 92E is equivalent to the third gear shaft 1131', and the gear 9E installed first is equivalent to the upper small gear 132' of the second-stage double gear 13'.

[0227] G station: Inject lubricating oil into the small gear 142' above the first-stage gear 122', large gear 131', small gear 132', large gear 141', and the third-stage double gear 14' to reduce gear wear and improve equipment stability;

[0228] like Figure 17 As shown:

[0229] The cylinder 2G on the frame 1 drives the lubricating oil injection head 1G on the slide plate 3G to inject lubricating oil into the housing 11'.

[0230] Station H: The output rotating component 15' is sent from the conveyor belt, and a magnet 16' is embedded in the recess 152' of the output rotating component 15'. The output rotating component 15' is clamped by a gripper and inserted into the second gear shaft 1121'. The large gear 151' below the output rotating component 15' meshes with the small gear 142' above the third-stage double gear 14'.

[0231] like Figure 18 , 19 As shown in Figures 20 and 21:

[0232] In this invention, a lower support plate 2H is fixed on a frame 1, and an upper turntable 31H and a positioning gear plate 33H are fixed on the motor shaft 3H of a motor (not shown in the figure, the motor can be a stepper rotary motor) fixed on the frame 1. The upper turntable 31H is located above the lower support plate 2H.

[0233] The upper turntable 31H has 8 magnet receiving holes 32H evenly distributed around its circumference.

[0234] The positioning toothed disc 33H has eight circumferentially distributed teeth, the same number as the magnet accommodating through hole 32H.

[0235] A photoelectric sensor 34H is fixed on the frame 1. The teeth of the positioning toothed disc 3H pass through the photoelectric sensor 34H and can cut off the light of the photoelectric sensor 34H.

[0236] Two vertical magnet supply channels 41H and 42H are fixed on the frame 1, and magnets 16' are stacked in the vertical holes of each of the magnet supply channels 41H and 42H.

[0237] The vertical holes of magnet supply channels 41H and 42H are located above the circumference of the eight magnet receiving through holes 32H.

[0238] A vertical pressing cylinder 5H is fixed on the frame 1. The lower end of the pressing cylinder 5H is located above the circumference where the eight magnet receiving through holes 32H are located. A magnet dropping through hole is opened on the lower support plate 2H below the lower end of the pressing cylinder 5H (not shown in the figure, it is blocked by the upper turntable 31H).

[0239] The frame 1 is also equipped with a gear conveyor belt 81H. The output rotating part 15' in the gear conveyor belt 81 is pushed by the pushing mechanism towards the assembly workbench (not shown in the figure; the side of the frame 1 is the assembly workbench 100, on which the conveyed housing 11' is located).

[0240] A gear receiving groove 84H on a gear conveying block 83H is aligned with the output end of the gear conveyor belt 81H. The gear receiving groove 84H is located below the magnet drop-out through hole opened on the lower support plate 2H, that is, below the lower end of the pressing cylinder 5H.

[0241] An output rotating component 15' is pushed into a gear receiving groove 84H, such that the recess 152' above the output rotating component 15' is located below the magnet drop through hole, that is, below the lower end of the pressing cylinder 5H.

[0242] A pressure sensor (not shown in the figure) is installed on the lowering cylinder 5H to sense the pressure at the end of the lowering cylinder 5H.

[0243] The aforementioned motor, photoelectric sensor 34H, pressing cylinder 5H, pressure sensor, and gear conveyor belt 81H are all connected to and controlled by the control computer.

[0244] The frame 1 has a three-jaw positioning gripping block mechanism 69H. The three-jaw positioning gripping block mechanism 69H is existing technology. The three jaws can open and close to grip the cylinder and move it to the required position before putting it down.

[0245] A cylinder 82H is also fixed on the frame 1. The cylinder 82H pushes the gear conveyor block 83H to move horizontally on the slide rail 85H on the frame 1. The direction of movement is perpendicular to the gear conveyor belt 81H.

[0246] The three-claw positioning and gripping block mechanism 69H and the cylinder 82H are also connected to and controlled by the control computer.

[0247] The three-jaw positioning and gripping block mechanism 69H is equivalent to 69E described in the above E station. The drive mechanism of the three-jaw positioning and gripping block mechanism 69H is the same as that of the E station, and will not be described again.

[0248] In actual operation:

[0249] The action of inserting magnet 16' into the recess 152' of output rotating component 15' after it is conveyed from the conveyor belt:

[0250] When the motor shaft 3H rotates, the upper turntable 31H rotates, and an empty magnet receiving through hole 32H rotates to the bottom of the magnet supply channel 41H. The magnet 16' at the bottom of the magnet supply channel 41H falls into the magnet supply channel 41H due to gravity.

[0251] Before the magnet 16' is turned to the magnet drop hole opened on the lower support plate 2H, it is supported by the lower support plate 2H and will not fall down. It will be accommodated in the magnet accommodating hole 32H and rotate together with the upper turntable 31H.

[0252] When the upper turntable 31H rotates again, the magnet receiving through hole 32H containing the magnet 16' moves to the bottom of the magnet supply channel 42H. The magnet 16' at the bottom of the magnet supply channel 42H cannot fall into the magnet receiving through hole 32H that already contains the magnet 16'.

[0253] The upper turntable 31H in the figure rotates two more times, and the magnet receiving through hole 32H containing magnet 16' moves to the bottom of the pressing cylinder 5H. Magnet 16' falls from the magnet drop through hole on the lower support plate 2H into the lower recess 152'. The pressing cylinder 5H presses down to press magnet 16' into the recess 152'.

[0254] Because magnet 16' is tightly fitted into recess 152' to prevent it from falling out, if the pressure sensor senses too little pressure, it indicates that the gap between magnet 16' and recess 152' is too large, and the pressing cylinder 5H too easily presses magnet 16' into recess 152', suggesting that the fit between magnet 16' and recess 152' may be loose, requiring inspection. If the pressure sensor senses too much pressure, it indicates that magnet 16' may have a diameter larger than recess 152' or be misaligned, causing it to get stuck at the upper edge of recess 152' and cannot be pressed down further. In this case, the machine must be stopped to prevent an accident.

[0255] The motor can be a stepper motor, which controls the upper turntable 31H to rotate one grid at a time, and the lower cylinder 5H to press down in a timely manner, and the gear conveyor belt 81H to transport the rotating part 15' in a timely manner.

[0256] In this embodiment, since the positioning toothed disk 33H has eight circumferentially distributed teeth, the same number as the magnet accommodating through hole 32H, the teeth of the positioning toothed disk 33H pass through the photoelectric sensor 34H and can cut off the light of the photoelectric sensor 34H. Therefore, the positioning toothed disk 3H will cut off the light of the photoelectric sensor 34H once every 1 / 8 revolution. Cutting off the light of the photoelectric sensor 34H sends a signal to the control computer, causing the motor to stop, the upper turntable 31H to stop, and the lower cylinder 5H to press down to complete one operation. After the time is up, the motor starts to rotate again, and so on.

[0257] The cylinder 82H then pushes the gear conveyor block 83H in the opposite direction to move horizontally on the slide rail 85H on the frame 1. The output rotating component 15', which has the magnet 16' pressed in the concave hole 152', is sent to the three-jaw positioning gripping block mechanism 69H directly below. The other output rotating components 15' on the gear conveyor belt 81 are waiting for the next push.

[0258] The three-jaw positioning and gripping block mechanism 69H grips the output rotating part 15' from the gear receiving groove 84H and removes the housing 11' from the assembly workbench for installation.

[0259] The cylinder 82H then pushes the gear conveying block 83H, which no longer has an output rotating part 15' in the gear receiving groove 84H, to move horizontally on the slide rail 85H on the frame 1, and move it to the position where the gear receiving groove 84H is aligned with the output end of the gear conveyor belt 81H, that is, the gear receiving groove 84H is located below the magnet drop hole (that is, below the lower end of the pressing cylinder 5H).

[0260] The two magnet supply channels 41H and 42H are for backup. During operation, the magnet 16' in magnet supply channel 41H first falls into the empty magnet receiving through hole 32H. When there is no magnet 16' in magnet supply channel 41H, the empty magnet receiving through hole 32H rotates to the bottom of magnet supply channel 42H, and the magnet 16' in magnet supply channel 42H will fall into the empty magnet receiving through hole 32H. This provides a buffer time for the operator to load magnet 16' into the empty magnet supply channel 41H or magnet supply channel 42H. This prevents the magnet receiving through hole 32H from being empty at one step and ending up below the pressing cylinder H5, resulting in the unqualified output rotating part 15' without a magnet being pressed into the concave hole 152' above the output rotating part 15'. This would lead to the unqualified output rotating part 15' without a magnet in the concave hole 152' being sent to the housing 11' to produce a defective product. This reduces the workload of the operators and improves the product qualification rate.

[0261] The H-station structure uses a vertical magnet supply channel to allow the magnets to descend by their own weight and cooperate with the upper turntable to achieve magnet separation and intermittent feeding. The lower support plate supports the magnets and transports them to the pressing hole position set in the lower support plate. The pressing cylinder presses the magnets into the concave hole on the top of the rotating part. The pressure sensor ensures the quality of pressing, and the positioning tooth plate and photoelectric sensor ensure the accuracy of positioning. Moreover, the entire process can be automatically operated without the need for skilled operators.

[0262] The output rotating component 15' is clamped by the grippers and inserted into the second gear shaft 1121'. The engagement action of the large gear 151' below the output rotating component 15' and the small gear 142' above the third-stage double gear 14' is the same as that of station E.

[0263] Gear 8E is equivalent to output rotating component 15', lower large gear 88E is equivalent to the lower large gear 151' of output rotating component 15', axle 92E is equivalent to the second gear shaft 1121', and the first installed gear 9E is equivalent to the upper small gear 142' of the third-stage double gear 14'.

[0264] Station I: The plastic partition 17' is conveyed from the conveyor belt, clamped by outward-expanding grippers, and transported to the position. The pressure head presses down into the housing 11', and the magnet 16' embedded in the recess 152' of the output rotating part 15' is exposed through the through hole 172' on the partition 17'.

[0265] like Figure 22 , Figure 23 , Figure 24 As shown:

[0266] The frame 1 is equipped with a belt conveyor 2I, and the partitions 17' of the electronic limiters are arranged sequentially on the belt conveyor 2I. There are four vertical through-hole posts 1711' on the partitions 17'. The four vertical through-hole posts 1711' are located at the vertices of a rectangle, that is, at the four corners of the partitions 17'. There are two through-hole posts 1711' on each side of the partitions 17'. The inner surface of the through-hole posts 1711' is an arc surface, and each through-hole post 1711' is provided with a through hole 171'.

[0267] The partition 17' inside the belt conveyor 2I is pushed toward the assembly workbench (not shown in the figure; the side of the frame 1 is the assembly workbench, on which the conveyed housing 11' is placed).

[0268] The frame 1 has a stop block 21I with a blocking partition 17' at the end of the belt conveyor 2I.

[0269] A cylinder 47I fixed on the frame 1 is connected to a connector 46I. The connector 46I is connected to and drives a horizontal moving plate 45I to move horizontally. A vertical sliding groove 44I is provided on the horizontal moving plate 45I. A vertical moving plate 42I is moved and embedded in the vertical sliding groove 44I. A cylinder 43I fixed on the horizontal moving plate 45I is connected to and drives the vertical moving plate 42I to move vertically in the vertical sliding groove 44I. A gripper 4I is installed on the vertical moving plate 42I. A gripper cylinder 41I installed on the vertical moving plate 42I is connected to and drives the gripper 4I to open and close.

[0270] The gripper 4I consists of two gripper plates 48I. Each gripper plate 48I has two arc-shaped vertical grooves 40I on its outer side. The axial distance between the two arc-shaped vertical grooves 40I is the same as the axial distance between the arc surfaces 1712' of the two corresponding through-hole columns 1711' on the same side of the partition plate 17'.

[0271] In actual work:

[0272] The first partition 17' on the belt conveyor 2I is blocked at the position of the stop block 21I.

[0273] At this time, the gripper 4I is closed.

[0274] The cylinder 43I drives the vertical moving plate 42I to move vertically downward in the vertical slide 44I until the two claws 48I of the gripper 4I are located above the middle of the partition 17', and each claw 48I has two through-hole posts 1711' on its outer side.

[0275] Then, the gripper cylinder 41I drives the gripper 4I to open, and each gripper piece 48I moves outward. The two arc-shaped vertical grooves 40I of each gripper piece 48I respectively abut against the arc surface 1712' of its corresponding through hole post 1711'. In this way, all four through hole posts 1711' are abutted, and the gripper 4I supports the through hole posts 1711' from the inside out.

[0276] Then, cylinder 43I drives vertical moving plate 42I to move vertically upward in vertical slide 44I, and gripper 4I supports through hole column 1711' and lifts partition plate 17'.

[0277] Then the cylinder 47I is connected via the connector 46I and drives the transverse moving plate 45I to move laterally toward the assembly worktable until it moves above the housing 11' that is already on the assembly worktable.

[0278] Then, cylinder 43I drives vertical moving plate 42I to move vertically downward in vertical slide 44I, placing partition 17' onto housing 11', and through hole 171' is located above the fixing hole of fixing block 114' inside housing 11';

[0279] Then the gripper cylinder 41I drives the gripper 4I to close and release the partition 17';

[0280] Then, cylinder 43I drives vertical moving plate 42I to move vertically upward in vertical slide 44I to the uppermost position;

[0281] Then, cylinder 47I is connected via connector 46I and drives transverse moving plate 45I to move laterally back to its original position.

[0282] Then the pressure head (not shown in the figure) presses down into the housing 11', and the magnet 16' embedded in the concave hole 152' of the output rotating component 15' is exposed through the through hole 172' on the partition plate 17'.

[0283] After one partition 17' is lifted away by the gripper 4, the next partition 17' is pushed by the belt conveyor 2 and blocked by the stop block 21, until the next cycle operation.

[0284] This I-station structure uses a conveyor belt and grippers with vertical grooves to support the four through-hole columns at the four corners of the partition, saving space and achieving automated and precise installation of the partition. The arc-shaped vertical grooves on the grippers make the support between them and the through-hole columns more reliable. Moreover, the entire process can be operated automatically without the need for skilled operators.

[0285] J station: Circuit board 18' is sent from the conveyor belt, suction cup picks up circuit board 18' and moves it onto housing 11' and puts it on partition 17';

[0286] like Figure 25 As shown:

[0287] The circuit board 18' is arranged in the tray 104, and is sucked by the suction cup 105 moving on the slide rail to the transmission belt 103 for conveying. Finally, it is moved to the housing 11' and placed on the partition 17'.

[0288] K station: The suction cup picks up the back cover 19', moves it onto the housing 11', and places it on the housing 11';

[0289] like Figure 26 As shown:

[0290] The rear cover 19' on conveyor belt 1K is held by suction cup 2K. A suction cup moving mechanism 3K, composed of cylinders, moves the rear cover 19' onto housing 11', placing the rear cover 19' onto housing 11'. The suction cup moving mechanism 3K and... Figure 7 The gripper drive mechanism at station A shown is the same.

[0291] Station L: Ultrasonic heating, the back cover 19' and the shell 11' are bonded together to obtain the finished product.

[0292] The ultrasonic heating head (not shown in the figure) is aligned with the back cover 19' and the housing 11' and ultrasonically heated and bonded to obtain the finished product.

In addition, operate to fix the external hook 121' extending from the first gear shaft hole 111' at the lower part of the input rotating part 12' to the external gear 10' located outside the housing 11'.

[0294] The aforementioned suction cups, cylinders, and conveyor belts are connected to a control computer. The control computer is an existing technology used to coordinate the operation of the components in sequence and under certain conditions.
