Description

Technical Field

[0001] The invention relates to the technical field of gear bearing press-fitting, in particular to a gear bearing assembly machine. Background Art

[0002] Gears are mechanical parts with teeth that can mesh with each other. They are widely used in mechanical transmission and the entire mechanical field. Sometimes, when using gears, they need to be used with bearings. Figure 1 As shown, the gear 100 includes a gear portion 110 and a hub portion 120. A positioning ridge 111 is provided on the inner wall of the shaft hole of the gear portion 110, and a corresponding groove 210 is provided on the outer wall of the bearing 200. During assembly, the groove 210 of the bearing 200 is aligned with the positioning ridge 111, and the bearing 200 is pressed into the shaft hole of the gear 100.

[0003] The current assembly method is as follows: the staff puts the bearing 200 into the shaft hole of the gear 100, and aligns the groove 210 with the positioning ridge 111, and then presses the bearing 200 into place through the corresponding press-fitting equipment. This assembly method has the following problems: 1. The manual assembly has high labor intensity and low production efficiency. 2. The bearing 200 is manually placed in the shaft hole, and the groove 210 is manually aligned with the positioning ridge 111. The groove 210 and the positioning ridge 111 are often not aligned.

[0083] like Figures 4 to 9 As shown, a gear bearing assembly machine according to an embodiment of the present invention includes:

[0084] A clamping head 1300, used for clamping the bearing 200 with the reverse side 230 facing downward;

[0085] A rotating power device 1400, the clamping head 1300 is connected to the rotating power device 1400 and can rotate horizontally under the drive of the rotating power device 1400;

[0086] The lifting power device 1500, the rotating power device 1400 is connected to the lifting power device 1500, and can drive the clamping head 1300 to rise to the first position and descend to the second position;

[0087] A fixed seat 1600, the fixed seat 1600 is provided with a track 1610 for an up and down guide travel, and the lifting power device 1500 is connected to the track 1610;

[0088] A pre-pressing power device 1700 is installed on the fixing seat 1600. The pre-pressing power device 1700 is provided with a telescopic rod 1710 that can be telescoped up and down. The telescopic rod 1710 is provided with an upper limit block 1720 and a lower limit block 1730 at intervals up and down.

[0089] A sliding connection block 1740, which is slidably mounted on the telescopic rod 1710 and is located between the upper limit block 1720 and the lower limit block 1730. The sliding connection block 1740 is connected to the lifting power device 1500;

[0090] A pre-compression spring 1750, which is sleeved on the telescopic rod 1710, wherein the upper end of the pre-compression spring 1750 abuts against the upper limit block 1720, and the lower end of the pre-compression spring 1750 abuts against the sliding connection block 1740;

[0091] The gear fixing device is used to fix the gear 100 and make the shaft hole of the gear 100 face the bearing 200 clamped by the clamping head 1300. When the clamping head 1300 is in the second position, the lower surface of the bearing 200 clamped by the clamping head 1300 is flush with the upper surface of the fixed gear 100.

[0092] The gear bearing press-fitting device 4100, the pre-pressed gear bearing is sent to the gear bearing press-fitting device 4100 for press-fitting;

[0093] The gear feeding and sorting mechanism 2000 is used to sort out the gears 100 with the shaft holes facing upwards;

[0094] The first feeding device 5000 is used to feed the gears 100 sorted out by the gear feeding and sorting mechanism to the gear fixing device for fixing;

[0095] The bearing feeding and sorting mechanism 3000 is used to sort out the bearings 200 with the reverse side facing downwards;

[0096] The second feeding device 1900 is used to convey the sorted bearings 200 to be clamped by the clamping head 1300 at the first position.

[0097] Specifically, refer to Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.13 As shown, the use process of the gear bearing assembly machine of the present invention is as follows:

[0098] 1. The gear 100 with the shaft hole facing upward is selected by the gear feeding and sorting mechanism 2000, and then the selected gear 100 is sent to the gear fixing device 11000 for fixing by the first feeding device 5000.

[0099] 2. The bearing 200 with the reverse side 230 facing downward is sorted out by the bearing feeding and sorting mechanism 3000, and then transported to a position where the clamping head 1300 can clamp it through the second feeding device 1900, so as to be clamped by the clamping head 1300 in the first position.

[0100] 3. The clamping head 1300 moves up and down with the rotating power device 1400 under the action of the lifting power device 1500. When the clamping head 1300 rises to the first position, the bearing 200 delivered by the second feeding device 1900 is clamped by the clamping head 1300, and the reverse side 230 of the clamped bearing 200 faces downward.

[0101] 4. The clamping head 1300 moves downward to the second position under the action of the lifting power device 1500. The second position is determined by the position fixed by the gear 100 during use, that is, when the clamping head 1300 moves to the second position, the lower surface of the bearing 200 clamped by the clamping head 1300 is flush with the upper surface of the gear 100 arranged below.

[0102] 5. The telescopic rod 1710 of the pre-stressing power device 1700 extends downward, the upper limit block 1720 moves downward, and the pre-stressing spring 1750 is squeezed. The pre-stressing spring 1750 applies a downward force to the sliding connection block 1740, so that the sliding connection block 1740 has a tendency to slide downward on the telescopic rod 1710, and then the lifting power device 1500 has a tendency to move downward on the track 1610. However, if the bearing 200 is not aligned with the gear 100 (that is, the groove 210 and the positioning ridge 111 are not aligned, so the positioning ridge 111 will prevent the bearing 200 from being pressed into the shaft hole of the gear 100), the bearing 200 cannot be further pressed into the shaft hole of the gear 100. Only after the bearing 200 is aligned with the gear 100, the force of the pre-stressing spring 1750 can be released, driving the lifting power device 1500 to move up and down on the track 1610, thereby pre-pressing the bearing 200 into the gear 100.

[0103] In order to align the bearing 200 with the gear 100 (that is, the groove 210 and the positioning ridge 111 are aligned), the rotating power device 1400 is rotated to drive the bearing 200 to rotate slowly. During the rotation of the bearing 200, once the groove 210 and the positioning ridge 111 are aligned, the resistance to the bearing 200 disappears, and under the action of the preload spring 1750, the lifting power device 1500 is driven up and down on the track 1610, thereby preloading the bearing 200 into the gear 100, completing the alignment preloading of the gear 100 (the elongation of this preload spring 1750 is not large, and can only complete a certain preloading depth).

[0104] After the preloading is completed, the rotating power device 1400 stops rotating, the clamping head 1300 releases the bearing 200, the telescopic rod 1710 of the preloading power device 1700 shrinks upward, and the sliding connection block 1740 moves upward with the lower limit block 1730, and the sliding connection block 1740 drives the lifting power device 1500 back to the initial position. Then, under the action of the lifting power device 1500, the clamping head 1300 rises to the first position, re-clamps the new bearing 200, and performs the next round of preloading installation.

[0105] 6. The pre-pressed gear bearing is pressed by the gear bearing pressing device 4100 to completely press the bearing 200 into the shaft hole of the gear 100, completing the pressing work and obtaining the final pressed product.

[0106] In some embodiments of the present invention, the lifting power device 1500 is a lifting cylinder, which is connected to the track 1610 through the mounting seat 1510. The lifting cylinder is provided with a lifting output shaft, and the rotating power device 1400 is connected to the lifting output shaft. The mounting seat 1510 is provided with a position sensor 1800 for checking the position height of the mounting seat 1510.

[0107] Specifically, since the distance between the first position and the second position is determined, the lifting output shaft of the lifting cylinder only needs to set the stroke of up and down movement to drive the rotary power device 1400 to move up and down, thereby driving the clamping head 1300 to rise to the first position and descend to the second position. In addition, the lifting cylinder is connected to the track 1610 through the mounting seat 1510, and the mounting seat 1510 slides up and down on the track 1610 to drive the lifting cylinder to move up and down. More specifically, the sliding connection block 1740 is connected to the mounting seat 1510 to drive the mounting seat 1510 to move.

[0108] Further, such as Fig.10 As shown, by providing a position sensor 1800 on the mounting seat 1510, when the sliding connection block 1740 drives the mounting seat 1510 downward so that the bearing 200 is pre-pressed into the gear 100, the position sensor 1800 will detect that the position height of the mounting seat 1510 is reduced, thereby determining that the bearing 200 is pre-pressed into the gear 100.

[0109] If the position sensor 1800 does not detect a change in the height of the mounting seat 1510 after the rotary power device 1400 rotates continuously for a period of time, it may be that the equipment is not calibrated, resulting in the bearing 200 not being aligned with the shaft hole of the gear 100. Or the product has quality problems and cannot be pressed in (such as burrs in the shaft hole of the gear 100). In this case, the product is determined to be a defective product, and the rotary power device 1400 is controlled to stop rotating to avoid wasting time and affecting production efficiency. It is determined to be a defective product and sent to the defective product area. By setting the position sensor 1800, the pre-pressure condition of the gear 100 and the bearing 200 can be effectively determined, and the situation can be analyzed.

[0110] In some embodiments of the invention, the lower limit block 1730 is movably connected to the telescopic rod 1710, and the position height of the lower limit block 1730 can be adjusted. Specifically, the lower limit block 1730 is a connecting bolt, and the connecting bolt is connected to the lower end of the telescopic rod 1710 through a thread, and the connecting bolt can be separated from the telescopic rod 1710, so that it is convenient to install the pre-compression spring 1750 and the sliding connection block 740 on the telescopic rod 710.

[0111] At the same time, by adjusting the connection position of the connection bolt, the distance between the upper limit block 1720 and the lower limit block 1730 can be adjusted, and the movement stroke of the sliding connection block 1740 on the telescopic rod 1710 can be adjusted, thereby adjusting the up and down movement stroke of the lifting power device 1500. In addition, the telescopic adjustment amount of the pre-compression spring 1750 can also be adjusted to adjust the elastic force of the pre-compression spring 1750.

[0112] In some embodiments of the invention, the gear 100 includes a gear portion 110 and a hub portion 120, the diameter of the gear portion 110 is D1, the diameter of the hub portion 120 is D2, the total height of the gear 100 is H1, the height of the hub portion 120 is H2, wherein D1>H1, and the gear feeding and sorting mechanism 2000 includes:

[0113] A gear conveyor belt 2300, on which a gear loading station 2310 and a gear unloading station 2320 are arranged;

[0114] The first feeding device 2400 is used to feed the gear 100 to the gear loading station 2310;

[0115] The first gear sorting station is arranged between the gear loading station 2310 and the gear unloading station 2320. The first gear sorting station is provided with a first height limiting plate 2500. The first height limiting plate 2500 is arranged above the gear conveyor belt 2300. A first channel 2510 is formed between the first height limiting plate 2500 and the gear conveyor belt 2300. The height of the first channel 2510 is H3, and D1>H3≥H1;

[0116] The second gear sorting station is arranged between the first gear sorting station and the gear unloading station 2320. The second gear sorting station is provided with two guide rails 2600. The two guide rails 2600 are arranged in parallel on both sides of the gear conveyor belt 2300 and along the conveying direction of the gear conveyor belt 2300. A second channel 2610 is formed between the two guide rails 2600. The height of the second channel 2610 is H4, H4<H2, and the width of the second channel 2610 is L1, D1>L1≥D2.

[0117] refer to Fig.14 , Fig.15 , Figure 1 , Fig.17 , Fig.18 As shown, the sorting of the gear 100 includes the following process:

[0118] 1. The gears 100 in various orientations are sent to the gear loading station 2310 through the first feeding device 2400. The gears 100 sent to the gear loading station 2310 mainly include: Fig.17 There are three states: state 1, state 2 and state 3.

[0119] 2. When the gear 100 is conveyed by the gear conveyor belt 2300 and passes through the first gear sorting station, under the action of the first height limiting plate 2500, only the gears 100 in state 1 and state 2 can pass through the first channel 2510, while the gear 100 in state 3 cannot pass through the first channel 2510 because D1>H3. The gear 100 in state 3 is finally picked out from one side of the gear conveyor belt 2300, completing the first screening.

[0120] 3. The gears 100 in state 1 and state 2 continue to move along the gear conveyor belt 2300. When the gears 100 in state 1 and state 2 pass through the second gear sorting station, under the action of the two guide rails 2600, the gear 100 in state 1 can pass through the second channel 2610, while the gear in state 2 cannot pass through the second channel 2610 because D1>L1. The gear 100 in state 2 is removed from one side of the gear conveyor belt 2300. Finally, only the gear 100 in state 1 enters the gear unloading station 2320, thereby obtaining the gear 100 with the shaft hole facing upward.

[0121] The present invention utilizes the structure of the gear 100 itself and a mechanical mechanism to eliminate unnecessary gears 100 in state 2 and state 3 through two screenings, and obtains the gear 100 in state 1, which is convenient for subsequent assembly with the bearing 200.

[0122] In some embodiments of the present invention, the first feeding device 2400 includes a first hopper 2410 and a first lifting and pushing plate 2420. The first hopper 2410 is provided with a first hopper bottom 2411 and a first hopper mouth 2412. The first hopper mouth 2412 is provided with a first discharge side. The first discharge side is arranged corresponding to the gear loading station 2310. The first discharge side and the gear conveyor belt 2300 are arranged flush. The first lifting and pushing plate 2420 is arranged in the first hopper 2410. The first lifting and pushing plate 2420 is in contact with the inner wall of the discharge side of the first hopper mouth 2412. The first top end surface 2421 of the first lifting and pushing plate 2420 is an inclined surface. The first top end surface 2421 is inclined toward the first discharge side. The first lifting and pushing plate 2420 can move up and down from the first hopper bottom 2411 to the first hopper mouth 2412.

[0123] Specifically, Figure 14 to Figure 16As shown, during the loading process, a large number of gears 100 are first thrown into the first hopper 2410, and the first lifting and pushing plate 2420 is lifted upward from the first hopper bottom 2411 until the first top end surface 2421 exceeds the discharge side of the first hopper mouth 2412. During the rising process of the first lifting and pushing plate 2420, since the first lifting and pushing plate 2420 is in contact with the inner wall of the discharge side of the first hopper mouth 2412, the gears 100 accumulated on the first top end surface 2421 will move upward along with the first lifting and pushing plate 2420. Since the first top end surface 2421 is inclined, after the first top end surface 2421 exceeds the discharge side of the first hopper mouth 2412, the gears 100 accumulated on the surface of the first top end surface 2421 will slide out from the discharge side along the inclined surface and fall onto the gear loading station 2310, completing the loading. Afterwards, the first lifting and pushing plate 2420 descends back to the initial position, and the gear 100 in the first hopper 2410 is sent to the first top end surface 2421 again to prepare for the next round of loading.

[0124] In a further embodiment of the present invention, the first bucket bottom 2411 is provided with a first opening, the first lifting and pushing plate 2420 can be installed in the first opening so as to be raised and lowered and slidable, and can seal the first opening, and the first bucket bottom 2411 is an inclined surface, and is inclined toward the first opening.

[0125] In this embodiment, an opening is set at the first bucket bottom 2411, and the cross-sectional shape of the first lifting and pushing plate 2420 is consistent with the shape of the opening. The first lifting and pushing plate 2420 is installed in the opening and moves up and down through the opening, so that the first top end surface 2421 can be lowered to a position lower than the first bucket bottom 2411, so that the gear 100 in the first hopper 2410 can smoothly enter the first top end surface 2421.

[0126] In addition, by setting the first hopper bottom 2411 as an inclined surface, the gear 100 in the first hopper 2410 will slide along the inclined surface toward the opening, thereby entering the first top end surface 2421. In other embodiments, some mechanical devices can also be used to push the gear in the first hopper 2410 onto the first top end surface 2421.

[0127] In a further embodiment of the present invention, a first baffle 2700 is provided on one side of the gear conveyor belt 2300, the first baffle 2700 is arranged on a side away from the first hopper 2410, and the first baffle 2700 is arranged along the direction from the gear loading station 2310 to the gear unloading station 2320;

[0128] It also includes a primary screening plate 2800, which is provided with a screening plate surface 2810, which is arranged above the gear loading station 2310, and the screening plate surface 2810 is arranged toward the gear conveyor belt 2300, and the minimum height between the screening plate surface 2810 and the gear conveyor belt 2300 is H5, D1>H5≥H1;

[0129] The screening plate surface 2810 is an inclined surface, which is arranged to be inclined upward from the first baffle 2700 to the first hopper 2410 .

[0130] By providing the first baffle 2700 on one side of the gear conveyor belt 2300 , it is possible to prevent part of the gear 100 from being squeezed out from the other side of the gear conveyor belt 2300 when the first lifting and pushing plate 2420 pushes the gear 100 to the gear conveyor belt 2300 .

[0131] like Fig.16 As shown, in the process of the first lifting and pushing plate 2420 pushing the gear 100 to the gear conveyor 2300, because the minimum height between the screening plate surface 2810 and the gear conveyor 2300 is H5, and D1>H5≥H1. Therefore, the gears 100 in state 1 and state 2 can enter the gear loading station 2310, while the gears 100 in state 3 cannot enter the gear loading station 2310, or after entering, they will be transformed into state 1 or state 2 under the action of the primary screening plate 2800, thereby completing the preliminary screening of the gears. Some other gears in an inclined state can also enter the gear loading station 2310 later, but the gears 100 will also become state 1 or state 2 under the action of their own gravity.

[0132] The screening plate surface 2810 is set as an inclined surface, so that even the gear in state 3 can enter the gear loading station 2310, and under the action of the screening plate surface 2810, it is transformed from state 3 to state 1 or state 2.

[0133] In some other embodiments, the screening plate surface 2810 may also be a plane, which can directly restrict the gear 100 in state 3 from entering the gear loading station 2310.

[0134] In some embodiments of the present invention, a first recovery channel 2900 is further included. The first recovery channel 2900 is provided with a first recovery inlet and a first recovery outlet. The first recovery inlet and the entrance of the first channel 2510 and the entrance of the second channel 2610 are arranged correspondingly, and are used to receive and deliver the gear 100 dropped from the entrance of the first channel 2510 and the entrance of the second channel 2610. The first recovery outlet is connected to the second hopper 2410.

[0135] In some embodiments of the present invention, the gear fixing device includes a receiving seat 11100, a left clamping tool and a right clamping tool. The receiving seat 11100 is provided with a transfer groove 11110, and the transfer groove 11110 is provided with a pre-pressing position 11111. The hub portion 120 of the gear 100 can be placed in the pre-pressing position 11111. The left clamping tool and the right clamping tool are respectively arranged on both sides of the pre-pressing position for clamping both sides of the upper part of the gear 100.

[0136] The left clamping tool comprises a first clamping plate 11210 and a first power device. The first clamping plate 11210 is provided with a first opening groove. The first clamping plate 11210 is connected to the first power device to drive the first clamping plate 11210 to move toward the pre-pressing position 11111, so that the first opening groove is clamped on one side of the gear 100.

[0137] The right clamping tool comprises a second clamping plate 11310 and a second power device 11320. The second clamping plate 11310 is provided with a second opening groove 11311. The second clamping plate 11310 and the second power device 11320 are connected to drive the second clamping plate 11310 to move toward the pre-pressing position 11111, so that the second opening groove 11311 is clamped on the other side of the gear 100.

[0138] The transfer trough 11110 is also provided with a loading position 11112 and a pressing position 11113, which are arranged on both sides of the pre-pressing position 11111. The right clamping tool also includes a third power device 11400, which is connected to the second power device 11320 to drive the second power device 11320 to reciprocate along the groove direction of the transfer trough 11110.

[0139] The first feeding device 5000 can transfer the gear 100 at the gear unloading station 2320 to the loading station;

[0140] The gear bearing press-fitting device is correspondingly arranged at the press-fitting position.

[0141] Combination Figure 5 , Figure 6 , Fig.12 As shown, the fixed gear 100 includes the following process:

[0142] 1. The first feeding device 5000 transfers the gear 100 at the gear unloading station 2400 to the loading station 11112.

[0143] 2. Transfer the gear 100 at the loading position 11112 to the pre-pressing position 11111. Specifically, the second clamping plate 11310 moves along the trough 11110 driven by the third power device 11400 and the second power device 11320 to transfer the gear 100 at the loading position 11112 to the pre-pressing position 11111.

[0144] 3. When the gear 100 is sent to the pre-pressing position 11111, the hub portion 120 of the gear 100 is in the transfer trough 11110, and the gear 100 is clamped and fixed by a left clamping fixture and a right clamping fixture respectively arranged on both sides of the pre-pressing position 11111.

[0145] Specifically, when the left clamping tool and the right clamping tool clamp the gear 100, the first power device drives the first clamping plate 11210 to move toward the pre-pressing position 11111, and the first opening groove is clamped on one side of the gear 100. The second power device 11320 drives the second clamping plate 11310 to move toward the pre-pressing position 11111, and the second opening groove 11311 is clamped on the other side of the gear 100, completing the clamping and fixing of the gear 100. After the pre-pressing installation is completed, the first clamping plate 11210 and the second clamping plate 11310 are withdrawn, and the clamping of the gear 100 is released, which facilitates the transportation of the gear 100.

[0146] 4. After the pre-pressing is completed, the second clamping plate 11310, driven by the third power device 11400 and the second power device 11320, continues to move along the groove direction of the transfer trough 11110, and transfers the gear 100 in the pre-pressing position 11111 to the pressing position 11113, and completes the final pressing under the action of the gear bearing pressing device 4100.

[0147] 5. After the press-fitting is completed, the second clamping plate 11310 continues to move along the groove direction of the transfer trough 11110 to bring the press-fitted product out of the transfer trough 11110.

[0148] 6. All components return to their positions and prepare for the next round of pressing.

[0149] In some embodiments of the present invention, the bearing 200 has a front side 220 and a back side 230, the diameter of the bearing 200 is A1, the height of the bearing 200 is A2, A1>A2, and the bearing feeding and sorting mechanism 30000 includes:

[0150] A bearing conveyor belt 3300, on which a bearing loading station 3310 and a bearing unloading station 3320 are arranged;

[0151] The second feeding device 3400 is used to feed the bearing 200 to the bearing feeding station 3310;

[0152] The first bearing sorting station is arranged between the bearing loading station 3310 and the bearing unloading station 3320. The first bearing sorting station is provided with a second height limiting plate 3500. The second height limiting plate 3500 is arranged above the bearing conveyor belt 3300. A third channel is formed between the second height limiting plate 3500 and the bearing conveyor belt 3300. The height of the third channel is A3, and A1>A3≥A2;

[0153] The second bearing sorting station is arranged between the first bearing sorting station and the bearing unloading station 3320. The second bearing sorting station is provided with a turntable 3600. The turntable 3600 is horizontally rotatably arranged on the bearing conveyor belt 3300. The outer edge of the turntable 3600 is provided with an open slot 3610. The open slot 3610 is adapted to the bearing 200. The open slot 3610 runs through the plate surface of the turntable 3600. The bearing conveyor belt 3300 is located on the rotation path of the open slot 3610.

[0154] The bearing plate 3700 is located in the rotation direction of the rotating plate 3600. The bearing plate 3700 is provided with a bearing surface, which is located below the rotating plate 3600 and is used to bear the bearing 200 in the opening slot 3610. The bearing surface is connected to the bearing conveyor belts 3300 on both sides of the rotating plate 3600. The bearing plate 3700 is provided with a blanking port 3710, which is located below the movement path of the opening slot 3610.

[0155] An opening and closing mechanism 3800 is used to open and close the blanking opening 3710;

[0156] The bearing detection device 3900 is used to detect the orientation of the front side 220 and the back side 230 of the bearing 200 entering the open slot 3610 .

[0157] refer to Figure 19 to Figure 23 As shown, the sorting of bearing 200 includes the following process:

[0158] 1. The bearings 200 are delivered to the bearing loading station 3310 through the second feeding device 3400. The bearings 200 in various states move along the bearing conveyor belt 3300. When passing through the third channel, the height of the third channel is A3, A1>A3≥A2. Therefore, only the bearings 200 in the lying state can pass through the third channel, while the bearings 200 in the upright state cannot pass through the third channel and are squeezed out of the bearing conveyor belt 3300, completing the first sorting. At this time, the sorted bearings 200 include two states: front side facing up and back side facing up.

[0159] 2. The sorted bearings 200 continue to move along the bearing conveyor belt 3300, enter the open slots 3610 of the turntable 3600 one by one, and move along with the open slots 3610. The bearing detection device 3900 detects whether the bearing 200 entering the open slots 3610 is facing up with the front side 220 or the back side 230. When it is detected that the bearing 200 is facing up with the front side 220, the bearing 200 moves along the open slots 3610 until it returns to the bearing conveyor belt 3300 again, and finally moves along the bearing conveyor belt 3300 to the bearing unloading station 3320.

[0160] When it is detected that the bearing 200 has the reverse side 230 facing upward, and when the bearing 200 moves to the drop port 3710 along the open slot 3610, the opening and closing mechanism 3800 controls the drop port 3710 to open, so that the bearing 200 falls from the drop port 3710 and is sorted out, completing the second screening, and finally only the bearing 200 with the front side 220 facing upward remains.

[0161] Among them, the joint between the load-bearing surface and the bearing conveyor belt 3300 (not directly connected), the load-bearing surface and the conveying surface of the bearing conveyor belt 3300 are preferably set flush, which helps the bearing 200 to smoothly enter the load-bearing surface from the bearing conveyor belt 3300, and then enter the bearing conveyor belt 3300 again from the load-bearing surface.

[0162] In addition, the bearing detection device 3900 is a visual recognition system. Figure 1 As shown, the front side of the current bearing 200 is generally provided with a mark, and the visual recognition system determines the orientation of the bearing 200 by whether the corresponding mark is detected.

[0163] In some embodiments of the present invention, the second feeding device 3400 includes a second hopper 3410 and a second lifting and pushing plate 3420. The second hopper 3410 is provided with a second hopper bottom 3411 and a second hopper mouth 3412. The second hopper mouth 3412 is provided with a discharge side, and the discharge side is arranged corresponding to the bearing loading station 3310. The discharge side and the bearing conveyor belt 3300 are arranged flush. The second lifting and pushing plate 3420 is arranged in the second hopper 3410. The second lifting and pushing plate 3420 is in contact with the inner wall of the discharge side of the second hopper mouth 3412. The second top end surface 3421 of the second lifting and pushing plate 3420 is an inclined surface, and the second top end surface 3421 is inclined toward the discharge side. The second lifting and pushing plate 3420 can move up and down from the second hopper bottom 3411 to the second hopper mouth 3412.

[0164] Specifically, Figure 19 to Figure 21As shown, during the loading process, a large number of bearings 200 are first thrown into the second hopper 3410, and the second lifting and pushing plate 3420 is lifted upward from the second hopper bottom 3411 until the second top end surface 3421 exceeds the discharge side of the second hopper mouth 3412. During the rising process of the second lifting and pushing plate 3420, since the second lifting and pushing plate 3420 is in contact with the inner wall of the discharge side of the second hopper mouth 3412, the bearings 200 accumulated on the second top end surface 3421 will move upward along with the second lifting and pushing plate 3420. Since the second top end surface 3421 is inclined, after the second top end surface 3421 exceeds the discharge side of the second hopper mouth 3412, the bearings 200 accumulated on the surface of the second top end surface 3421 will slide out from the discharge side along the inclined surface and fall onto the bearing loading station 3310, completing the loading. Afterwards, the second lifting and pushing plate 3420 descends back to the initial position, and the bearing 200 in the second hopper 3410 is sent to the second top end surface 3421 again, ready for the next round of loading.

[0165] In a further embodiment of the present invention, the second bucket bottom 3411 is provided with an opening, and the second lifting and pushing plate 3420 is installed in the opening in a lifting and sliding manner and can seal the opening.

[0166] In this embodiment, an opening is set in the second bucket bottom 3411, and the cross-sectional shape of the second lifting and pushing plate 3420 is consistent with the shape of the opening. The second lifting and pushing plate 3420 is installed in the opening and moves up and down through the opening, so that the second top end surface 3421 can be lowered to a position lower than the second bucket bottom 3411, so that the bearing 200 in the second hopper 3410 can smoothly enter the second top end surface 3421.

[0167] In a further embodiment of the present invention, the second bucket bottom 3411 is an inclined surface and is inclined toward the opening direction.

[0168] In this embodiment, by setting the second hopper bottom 3411 as an inclined surface, the bearing 200 in the second hopper 3410 will slide along the inclined surface toward the opening, thereby entering the second top end surface 3421. In other embodiments, some mechanical devices can also be used to push the bearing 200 in the second hopper 3410 onto the second top end surface 3421.

[0169] In some embodiments of the present invention, a second baffle 3330 is provided on one side of the bearing conveyor belt 3300 , and the second baffle 3330 is arranged on the side away from the second hopper 3410 , and the second baffle 3330 is arranged along the direction from the bearing loading station 3310 to the bearing unloading station 3320 .

[0170] By providing a second baffle 3330 on one side of the bearing conveyor belt 3300, it is possible to prevent some bearings 200 from being squeezed out from the other side of the bearing conveyor belt 3300 when the second lifting and pushing plate 3420 pushes the bearings 200 to the bearing conveyor belt 3300. By providing the second baffle 3330, the excess material on the bearing conveyor belt 3300 can only be squeezed back into the second hopper 3410 and re-enter the loading process until all the bearings 200 are finally sorted.

[0171] In some embodiments of the present invention, a second recovery channel 3430 is further included. The second recovery channel 3430 is provided with a second recovery inlet and a second recovery outlet. The second recovery inlet is arranged below the side of the bearing conveyor belt 3300 away from the second baffle 3330. The second recovery inlet is arranged along the bearing conveyor belt 3300 and is located below the drop port 3710. The second recovery outlet is connected to the second hopper 3410.

[0172] The bearing 200 squeezed out from the bearing conveyor belt 3300 and dropped from the drop port 3710 falls into the second recovery channel 3430 from the second recovery inlet and returns to the second hopper 3410 from the second recovery outlet.

[0173] In some embodiments of the present invention, an arc-shaped baffle 3720 is provided on the bearing surface, and the arc-shaped baffle 3720 is arranged along the outer edge of the rotating disk 3600 to limit the bearing 200 in the opening slot 3610 from escaping from the 3 opening slots 610 .

[0174] By setting the arc baffle 3720, the direction of the arc baffle 3720 is consistent with the outer edge of the turntable 3600. The arc baffle 3720 can be set in close contact with the outer edge of the turntable 3600, or a certain distance can be maintained to prevent the bearing 200 from escaping from the open slot 3610 during the rotation of the turntable 600.

[0175] In some embodiments of the present invention, the second feeding device 1900 includes an incoming material rack 1910, a feeding rack 1920, a lifting seat 1930 and a horizontal pushing seat 1940. The incoming material rack 1910 is provided with an incoming material trough 1911, and the feeding rack 1920 is provided with a feeding rod 1921. The feeding rod 1921 is perpendicular to the outlet direction of the incoming material trough 1911, and the feeding rod 1921 is provided with a receiving material trough 1922. The receiving material trough 1922 is provided with a receiving port connected to the outlet of the incoming material trough 1911, and the inlet of the incoming material trough 1911 is connected to the bearing unloading station 3320. The lifting seat 1930 is connected to the feeding rack 1920 to drive the feeding rack 1920 to move up and down. The horizontal pushing seat 1940 is connected to the lifting seat 1930, and can drive the feeding rod 1921 to move in the direction of the receiving position and the feeding position.

[0176] Combination Fig.11As shown, the sorted bearings 200 come out from the bearing unloading station 3320, enter the incoming material trough 1911, and move along the incoming material trough 1911, and can come out from the outlet of the incoming material trough 1911.

[0177] When the feeding rack 1920 receives the material, the lifting seat 1930 and the horizontal pushing seat 1940 are used to make the receiving port of the receiving trough 1922 dock with the outlet of the incoming trough 1911, and the bearing 200 in the incoming trough 1911 is sent to the receiving trough 1922 to complete the material receiving action.

[0178] Subsequently, the feeding rack 1920 first rises under the action of the lifting seat 1930, so that the feeding rod 1921 blocks the outlet of the material trough 1911 to prevent the bearing 200 in the material trough 1911 from being discharged. After that, the feeding rack 1920, under the action of the horizontal pushing seat 1940, sends the bearing 200 to the bottom of the clamping head 1300 in the first position for clamping by the clamping head 1300.
