DETAILED DESCRIPTION

[0043] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0044] Please refer to Figure 1-14 ;

[0045] The hollow encoder assembly machine described in the present invention is to improve the assembly accuracy. It should be noted that the relevant mechanism implementation methods not mentioned in this application can refer to the relevant implementation methods in the public technical document "CN109693108B, a fully automatic assembly device for a rotary encoder for multimedia"; the encoder to be produced in the present invention is composed of five parts: "a bracket, a positioning piece, a swivel seat, a brush and a body". These five parts are pre-assembled in the front-end assembly mechanism 1 and the rear-end assembly mechanism 2 respectively, and then combined together. The transfer mechanism 3 located between the two is used to transfer the parts completed by the front-end assembly mechanism 1 to the rear-end assembly mechanism 2;

[0046] Referring to FIG. 3 , the front-end assembly mechanism 1 includes a conveying device 11 , on which are mounted a plurality of jigs 12 . Along the direction of travel of the conveying device 11 , a rotary seat loading device 13 , a rotary seat angle adjustment device 14 , a brush loading device 15 , and a riveting device 16 are sequentially mounted. First, the structural shape of the rotary seat is described: it includes a rotating shaft portion, a mounting portion extending horizontally along the end face of the rotating shaft portion, and six protrusions are provided on the end face of the mounting portion. These six protrusions are arranged in groups of two at 120° intervals, and a group of two protrusions is also arranged at intervals.

[0047] During operation, the swivel seat is placed in the jig 12 by the swivel seat loading device 13, and then moved to the swivel seat angle adjustment device 14 under the drive of the conveying device 11. In the prior art, the swivel seat angle is usually adjusted in advance at the swivel seat loading device 13, but the speed is very slow, resulting in material accumulation. In addition, the swivel seat adopts a vibrating plate loading method, which is affected by the vibrating plate and causes the swivel seat to deflect. The adjustment method is not ideal. Therefore, the present invention provides an independent angle adjustment device, which will not be affected by vibration.

[0048] One embodiment of the rotary seat angle adjustment device 14 of the present invention is shown in FIG. Figure 4, specifically including a lifting component 141 with a rotating component 142 installed at the moving end, and an adjusting block 143 installed at the output end of the rotating component 142. Preferably, an elastic member is provided between the adjusting block 143 and the output end of the rotating component 142 to play a buffering role; three adjusting openings 144 are provided on the periphery of the adjusting block 143, and the adjusting openings 144 are used to engage the protrusions on the swivel seat; the three adjusting openings 144 of the adjusting block 143 correspond exactly to the three groups of protrusions, and the protrusions outside the adjusting openings 144 are placed in the space between two adjacent groups of protrusions, corresponding to a swivel seat, and the rotating component 142 will drive the adjusting block 143 to rotate 360°; when the swivel seat reaches the specified position, the lifting component 141 pushes the rotating component 142 to descend. Assuming that the swivel seat is misaligned at this time, due to the lack of alignment Therefore, the lower end surface of the adjustment block 143 will conflict with the end of the protrusion, and then the rotating component 142 drives the adjustment block 143 to rotate, but does not drive the swivel seat to rotate. When the adjustment seat rotates to a certain angle, each group of protrusions corresponds to the adjustment opening 144 one-to-one, and the protrusions outside the adjustment opening 144 are placed in the space between the two adjacent groups of protrusions and continue to rotate. At this time, the protrusions conflict with the edges of the protrusions, and the adjustment block 143 can drive the swivel seat to rotate until the adjustment block 143 stops after rotating 360°. Finally, the lifting component 141 drives the rotating component 142 to rise, so that the adjustment seat is separated from the end surface of the swivel seat. Using this method, the adjustment block 143 rotates 360° as the limit, and the angle of the swivel seat can be accurately adjusted without considering the angular position of the swivel seat without being affected by the outside world.

[0049] After adjusting the angle of the swivel seat, the jig is driven by the conveying device 11 to move to the brush loading device 15, and the brush is placed on the swivel seat. The brush is provided with a number of clamping holes, which correspond to the convex points on the swivel seat one by one. The clamping holes and the convex points cooperate to fix the brush on the swivel seat; then it reaches the riveting device 16, and the convex points are flattened by the riveting device 16 to fix the brush to the swivel seat.

[0050] After the above installation process, the front section of the hollow encoder is assembled. While the front section assembly process is in progress, the rear section assembly mechanism 2 also begins to assemble; Figure 9 First, the bracket is placed in the second jig 22 through the bracket loading device 23, and then the positioning ring is stacked on the bracket through the positioning ring loading device 24. It should be noted that fixed feet are symmetrically provided on the bracket to limit the deviation of the positioning ring. Then, the jig is driven by the second conveying device 21 to move to the corresponding position of the transfer mechanism 3. The parts that have been oiled in the jig are placed in the second jig 22 and combined with the bracket and the positioning ring through the transfer mechanism 3, and then moved to the corresponding position of the body loading device 25. Before loading the body, the necessary positions of the body need to be oiled;

[0051] In one embodiment of the body loading device 25 of the present invention, referring to Figure 10-12 , including a body conveying component 251, a body placement seat 252, a body gap oiling component 253, a body outer wall oiling component 254 and a body loading component 255, wherein the body conveying component 251 is used to convey the body to the body placement seat 252, the body placement seat 252 has two placement positions and a storage channel, the two placement positions correspond to the body gap oiling component 253 and the body outer wall oiling component 254 respectively, the body is placed in the placement position 1, the placement position 2 and the storage channel in turn through the body conveying component 251, and the body is oiled by the body gap oiling component 253 and the body outer wall oiling component 254 respectively, realizing oiling without dead angles, so that the final finished product rotates more smoothly;

[0052] The main body structure of this embodiment includes a fixed portion, a connecting portion extending horizontally from the end surface of the fixed plate 1523, and a groove is provided on the end surface of the connecting portion close to the fixed portion. The main body gap oiling assembly 253 is used to oil the groove; specifically, it includes an oil pan 2531 located below the main body placement seat 252 and a cylindrical support frame 2532. The support frame 2532 has oiling heads 2533 at the upper and lower ends respectively. The support frame 2532 is connected to a rotating assembly 2534. The rotating assembly 2534 is connected to a second lifting assembly 2535. The lifting assembly 2535 drives the support frame 2532 to move up and down. The support frame 2532 is rotated by the rotating assembly 2534, so that the oiling heads 2533 at both ends work alternately to improve work efficiency. During operation, the oiling head 2533 at the lower end contacts the oil pan 2531, and then the supporting frame 2532 is rotated by the rotating assembly 2534, so that the oiling head 2533 after being oiled faces the main body. Then, the lifting assembly 2535 drives the entire body upward, so that the fixed part is inserted into the supporting frame 2532, and the oiling head 2533 corresponds to and contacts the groove to achieve oiling. In this embodiment, the rotating assembly 2534 can be a combination of a cylinder, a rack and a gear.

[0053] Then the body is transferred to the second placement position, and further operated through the outer wall oiling component 254 of the body, which specifically includes a rotating component 4 2541 and an oil squeezing component 2542. The output end of the rotating component 4 2541 is provided with a fixed seat 2543. The combination of the rotating component 4 2541 and the fixed seat 2 2543 can refer to the combination of the rotating component 2 41 and the fixed seat 1 44. The oil squeezing component 2542 corresponds to a circular oil felt 2544. A gear 2545 is provided at the center of the circular oil felt 2544. The gear 2545 is meshed with a gear set 2546. The gear set 2546 is connected to a drive motor 2547. When working, the body is placed in the second placement position, and The main body is fixed by fixing seat 2543, and then rotating assembly 4 2541 drives fixing seat 2543 to rotate, so that the main body rotates accordingly. At the same time, the oil squeezing assembly 2542 squeezes the lubricating oil to the circular felt 2544. The circular felt 2544 rotates through the combination of gears, gear set 2546 and drive motor 2547 to achieve 360° oiling of the side wall of the main body, and at the same time, the rotation is used to make the oiling more uniform. It should be noted that the center position of the circular felt 2544 should be provided with an output shaft connected to the gear, and the output shaft is provided with a fixed frame component to fix the position of the circular felt 2544 and the oil squeezing assembly 2542.

[0054] The body that has been oiled twice is taken out from the second fixing seat 2543 and placed in the material storage channel to wait for loading; then the body in the material storage channel is inserted into the bracket through the body loading assembly 255, and the outer wall and groove of the body respectively contact the inner wall of the rotating shaft part and the mounting part of the bracket, and the contact parts are all oiled to achieve smooth rotation;

[0055] At this time, the fixed foot is facing upwards, and the fixed frame needs to be flattened. Therefore, it needs to pass through the pre-riveting device 26 and the riveting device 3 27. The fixed foot is first pressed into 45° by the pre-riveting device 26, and then the fixed foot is flattened by the riveting device 3 27. In this way, the swivel seat can be fixed to the main body, and finally the finished product is taken out from the fixture 2 22 through the unloading device 28.

[0056] The present invention realizes the fully automatic production of hollow encoders through the combination of the above-mentioned mechanisms, positions the swivel seat more accurately during the production process, is faster, and realizes dead-angle oiling operation, thereby improving the smoothness of the rotation of the central control encoder and reducing the occurrence of jamming.

[0057] One embodiment of the brush feeding device 15 of the present invention is shown in FIG. Figure 5 and Figure 6, the brush is circular and is usually conveyed by a material belt, so it needs to be cut, and the shrapnel on the brush needs to be bent. In the prior art, two independent devices are required to operate. In this embodiment, the above two operations are realized during the conveying process; specifically, it includes a brush conveying assembly 151, and a processing structure 1 is installed on the brush conveying assembly 151. The processing structure 1 is provided with a material taking hole 1526, and a brush loading assembly 153 is provided at the position corresponding to the material taking hole 1526. The specific bending and cutting are completed in the processing structure 1, and then it reaches the material taking hole 1526, and the brush loading assembly 153 is extended into the material taking hole 1526 to obtain the cut brush. In this embodiment, the brush conveying assembly 151 can be a combination of a conveying channel and a pulling device, which can accurately control the stroke of each brush movement;

[0058] The processing structure 1 includes a cylinder 1521 installed at the bottom of the brush conveying assembly 151. The output end of the cylinder 1521 is connected to a movable plate 1522. A fixed plate 1523 is provided above the brush conveying assembly 151. The bottom surface of the fixed plate 1523 is provided with a plurality of bosses 1524 corresponding to the springs on the brush. The ends of the bosses 1524 are inclined. The movable plate 1522 is provided with a plurality of bosses 2 1525 corresponding to the bosses 1524. The ends of the bosses 2 1525 are provided with inclined surfaces, and the bosses 2 1525 can pass through the brush conveying assembly 151 and fit with the bosses 1 1524. During operation, the material strip passes through the processing structure 1 through the brush loading assembly 153, so that each brush reaches the bending and cutting position in turn.

[0059] When the bending position is reached, a number of through holes corresponding to the spring pieces are provided at the conveying channel, and the end of the first boss 1524 is located above the spring piece. Then, the movable plate 1522 is pushed upward by the first cylinder 1521, and the second boss 1525 passes through the conveying channel from the through hole and contacts the bottom surface of the spring piece, pushing the spring piece to bend upward, and finally making the upper end surface of the spring piece contact the bottom surface of the first boss 1524. The combination of the two inclined surfaces of the first boss 1524 and the second boss 1525 can not only bend the spring piece, but also form it into a fixed shape. It should be noted that the end of the first boss 1524 should be as close to the end surface of the spring piece as possible.

[0060] After the bending is completed, the cylinder 1521 drives the movable plate 1522 to descend, so that the boss 2 1525 is pulled out from the conveying channel, and the brush is pushed in the cutting position direction. When it reaches the cutting position, the brush just corresponds to the position of the material taking hole 1526, and then the cylinder 1521 drives the movable plate 1522 to rise again. A lower cutter (not shown) is provided at the movable plate 1522, and an upper cutter (not shown) is provided at the fixed plate 1523. The lower cutter passes through the conveying channel and combines with the upper cutter to cut the material strip, so that the brush is separated from the material strip.

[0061] In the embodiment of the present invention, referring to Figure 7 and Figure 8 The rotary seat oiling device 4 includes a rotating component 2 41, an oiling component 1 42 and an oiling component 2 43; the output end of the rotating component 2 41 is provided with a fixed seat 1 44; after completing the front-end assembly, the parts are taken out of the jig 12 by the transfer device and placed on the fixed seat 1 44, and the cylinder 2 421 is pushed to push the fixed block 1 422 upward, so that the oil injection part 1 423 is tilted toward the connection position between the rotating shaft and the mounting part, and at the same time, the cylinder 3 431 is pushed to push the fixed block 2 432 downward, so that the oil injection part 2 433 is tilted toward the inner side of the upper end portion of the rotating shaft; then the rotating component 2 41 drives the fixed seat 1 44 to rotate, so that the rotary seat rotates, and the lubricating oil is respectively applied to the connection between the rotating shaft and the mounting part, as well as the inner side of the rotating part. This design method realizes oiling without dead angles. These two parts are in contact with the bracket, the positioning ring and the fixed part of the body respectively, making the rotation smoother.

[0062] In the embodiment of the present invention, referring to Figure 13 and Figure 14 , the bracket needs to define its specific position before loading, the bracket loading device 23 includes a bracket conveying component 231, and the bracket conveying component 231 is provided with a bracket shaping component 232 and a bracket position detection component 233. Due to the limitation of the bracket conveying channel, the loading position of the bracket has only two directions, positive and negative, so it is only necessary to detect its direction. First, the fixed legs on the bracket are opened by the bracket shaping component 232 to facilitate the entry of the swivel seat, and then the position of the bracket is detected by the bracket position detection component 233. If the angle is found to be incorrect, the bracket can be rotated 180° by the rotating component 235 on the bracket loading component 234 when loading;

[0063] The bracket shaping assembly 232 includes a top pressure cylinder 2321, and the output end of the top pressure cylinder 2321 is connected to a pressure block 2322. The pressure block 2322 can be placed in the bracket to expand the fixed legs of the bracket.

[0064] The bracket position detection assembly 233 includes a horizontally arranged cylinder 5 2331, and a connecting plate 2332 is provided at the output end of the cylinder 5 2331. A probe 2333 and a fixed block 3 2334 are movably connected to the connecting plate 2332. The end of the probe 2333 can be placed in the notch on the side of the bracket. A return spring (not shown) is provided between the other end of the bracket and the fixed block 3 2334. A detection block 2335 is provided on one side of the probe 2333. The detection block 2335 is used in conjunction with a laser sensor 2336. First, the extension movement stroke of the cylinder 5 2331 is fixed. When the position of the bracket is inaccurate, The notch of the bracket is located on one side of the probe 2333. When the cylinder five 2331 is extended, the end of the probe 2333 is inserted into the notch. At this time, the probe 2333 block is separated from the laser sensor 2336. The controller detects the signal and drives the bracket to rotate 180° through the rotating component three 235 during loading to adjust the angle position. If the position of the bracket is exactly missing, the probe 2333 will hit the edge of the bracket after the cylinder five 2331 is extended, and the detection block 2335 is not separated from the laser sensor 2336. At this time, the system will not detect the signal, which means that the position of the bracket is accurate and there is no need to adjust the position.
