At the same time, it also avoids the problems of missing or wrong assembly during manual assembly, thereby improving assembly accuracy. Furthermore, there are two friction plate feeding mechanisms 300, namely, the first friction plate feeding mechanism 300 and the second friction plate feeding mechanism 300. The first friction plate feeding mechanism 300 is located between the rotating shaft feeding mechanism 200 and the spring plate feeding mechanism 400, and the second friction plate feeding mechanism 300 is located after the concave wheel feeding mechanism 600, that is, the rotating shaft needs to assemble the friction plate twice so that the spring plate, cam and concave wheel are sandwiched between the two friction plates.

The spring plate provides stable support force through elastic deformation, and the concave wheel and cam cooperate with each other to enable the screen to realize the functions of opening, closing and rotating. Furthermore, the moving drive member 130 is a motor or a cylinder.

[0055] In the above-mentioned assembly device 10 for the notebook shaft, the conveyor frame 120 is provided with a receiving groove 120a, and the receiving groove 120a is used to receive the shaft. The mobile driving member 130 drives the conveyor frame 120 to sequentially pass through the shaft feeding mechanism 200, the friction plate feeding mechanism 300, the spring plate feeding mechanism 400, the cam feeding mechanism 500 and the concave wheel feeding mechanism 600.

[0056] like Figure 2 As shown, in one embodiment, the conveying frame 120 includes a rotating bracket body 121 and a mounting frame body 122, the rotating bracket body 121 is installed at the power output end of the mobile driving member 130, the rotating shaft feeding mechanism 200, the friction plate feeding mechanism 300, the spring feeding mechanism 400, the cam feeding mechanism 500 and the cam wheel feeding mechanism 600 are arranged around the rotating bracket body 121, the mobile driving member 130 is used to drive the rotating bracket body 121 to rotate, the accommodating groove 120a is opened in the rotating bracket body 121, and the mounting frame body 122 is fixedly connected to the machine 110.

[0057] In this embodiment, the rotating bracket body 121 is circular, and the rotating shaft feeding, friction plate feeding mechanism 300, spring plate feeding mechanism 400, cam feeding mechanism 500 and concave wheel feeding mechanism 600 are arranged around the rotating bracket body 121. The mobile driving member 130 drives the rotating bracket body 121 to rotate, so that the assembly space inside the device is more utilized, which is more conducive to the miniaturization design of the device. The accommodating groove 120a is opened in the rotating bracket body 121, so that the rotating shaft in the accommodating groove passes through the friction plate feeding mechanism 300, spring plate feeding mechanism 400, cam feeding mechanism 500 and concave wheel feeding mechanism 600 in sequence, so that the friction plate, spring plate, cam and concave wheel are sleeved on the rotating shaft in sequence. Furthermore, the mounting frame body 122 is located above the rotating bracket body 121, and the mounting frame body 122 is fixedly connected to the machine 110. The mounting frame body 122 provides an installation position for the first feeding assembly 220, the second feeding assembly 320, the third feeding assembly 420, the fourth feeding assembly 520 and the fifth feeding assembly 620.

[0058] like Figure 3 As shown, in one embodiment, the first feeding assembly 220 includes a first rotating driving member 221, a rotating tray 222, a first bracket 223, a second bracket 224, a first vertical driving member 225, a first horizontal driving member 226, a first cylinder 227 and two first clamping plates 228, the first bracket 223 is installed on the machine 110, the first rotating driving member 221 is connected to the first bracket 223, the rotating tray 222 is connected to the power output end of the first rotating driving member 221, the rotating tray 222 is provided with an embedding groove, and the first rotating driving member 221 drives the rotating tray 222 to rotate so that the embedding groove is connected to the feeding channel of the first loading tray 210;

[0059] The second bracket 224 is connected to the mounting frame body 122, the first horizontal driving member 226 is installed on the second bracket 224, the power output end of the first horizontal driving member 226 is connected to the first vertical driving member 225, the power output end of the first vertical driving member 225 is connected to the first cylinder 227, and the power output end of the first cylinder 227 is respectively connected to the two first clamping plates 228 to make the two first clamping plates 228 approach or move away from each other.

[0060] In this embodiment, the first loading tray 210 is used to transport the rotating shaft, but the rotating shaft transported by the first loading tray 210 is placed horizontally, and the rotating shaft needs to be rotated 90° in order to insert the rotating shaft into the receiving groove 120a. Specifically, when the rotating tray 222 is in the initial position, the embedding groove of the rotating tray 222 is connected to the feeding channel of the first loading tray 210. After the first loading tray 210 conveys the rotating shaft into the embedding groove, the first rotating driving member 221 drives the rotating tray 222 to rotate, so that the rotating tray 222 rotates 90°. At this time, the rotating shaft changes from a horizontal setting to a vertical setting. The first horizontal driving member 226 indirectly drives the clamping plate to move horizontally, and the first vertical driving member 225 indirectly drives the clamping plate to move vertically, so that the two clamping plates are located above the rotating tray 222. The first cylinder 227 drives the two clamping plates to approach each other to clamp the rotating shaft, and then the first vertical driving member 225 and the first horizontal driving member 226 drive the clamping plates to move above the accommodating groove 120a. The first cylinder 227 drives the two clamping plates to move away from each other to place the rotating shaft in the accommodating groove 120a. Finally, the two clamping plates are reset to complete the loading operation of the rotating shaft. Furthermore, the first vertical driving member 225 and the first horizontal driving member 226 are motors or cylinders.

[0061] like Figure 4 As shown, in one embodiment, the second feeding assembly 320 includes a third bracket 321, a second vertical driving member 322, a second horizontal driving member 323 and a first adsorption member 324, the third bracket 321 is connected to the mounting frame body 122, the second horizontal driving member 323 is installed on the third bracket 321, the second vertical driving member 322 is connected to the power output end of the second horizontal driving member 323, and the power output end of the second vertical driving member 322 is connected to the first adsorption member 324, so that the first adsorption member 324 adsorbs the friction plate of the second loading tray 310 to the rotating shaft in the accommodating groove 120a.

[0062] In this embodiment, the first adsorption member 324 is a suction cup, because the material of the friction plate is relatively soft, and the clamping method cannot conveniently and accurately insert the friction plate into the rotating shaft. Specifically, the second horizontal driving member 323 drives the first adsorption member 324 to move in the horizontal direction, and the second vertical driving member 322 drives the first adsorption member 324 to move in the vertical direction, so that the first adsorption member 324 moves to the top of the second loading tray 310. After the first adsorption member 324 adsorbs the friction plate, the second horizontal driving member 323 and the second vertical driving member 322 drive the first adsorption member 324 to move to the top of the rotating shaft, so that the first adsorption member 324 inserts the friction plate onto the rotating shaft.

[0063] like Figure 5 As shown, in one embodiment, the third loading tray 410 is provided with a first feeding channel 411 and a second feeding channel 412, and the first feeding channel 411 and the second feeding channel 412 are both used to transport shrapnel, and the shrapnel of the first feeding channel 411 is opposite to the shrapnel of the second feeding channel 412. It can be understood that multiple shrapnel need to be installed in the rotating shaft, and each shrapnel has a front and a back side, and the order of loading two adjacent shrapnel on the rotating shaft is opposite, so that the multiple shrapnel provide sufficient deformation for the rotating shaft, thereby making the screen rotation function more stable. In this embodiment, the first feeding channel 411 and the second feeding channel 412 are both used to transport shrapnel, and the shrapnel transported by the first feeding channel 411 is facing up, and the shrapnel transported by the second feeding channel 412 is facing up, so that the shrapnel is more accurate and quick when loading.

In this embodiment, when the first cut block 423 is at the initial position, the material slot of the first cut block 423 is connected to the first feeding channel 411, and when the spring piece in the first feeding channel 411 enters the material slot of the first cut block 423, the second cylinder 422 drives the first cut block 423 to move, so as to transport the spring piece to a predetermined position, so as to facilitate the adsorption of the second adsorption member 420a, thereby improving production efficiency.

[0065] like Figure 5As shown, in one embodiment, the third cylinder 424 is connected to the fourth bracket 421, the second cut block 425 is connected to the power output end of the third cylinder 424, the material trough of the second cut block 425 is connected to the second feeding channel 412, and the third cylinder 424 drives the second cut block 425 to transport the spring in the second feeding channel 412 to a preset position. In this embodiment, the third cylinder 424 drives the second cut block 425 to move, so as to move the spring on the second feeding channel 412 to a predetermined position, so as to facilitate the adsorption of the second adsorption member 420a. Through the cooperation between the first cut block 423 and the second cut block 425, the springs in two different directions can be continuously fed, further improving the production efficiency.

[0066] like Figure 5 As shown, in one embodiment, the third feeding assembly 420 also includes a fifth bracket 426, a third vertical driving member 427, a second rotating driving member 428, a rotating bracket 429 and a second adsorption member 420a, the fifth bracket 426 is installed on the mounting frame body 122, the second rotating driving member 428 is connected to the fifth bracket 426, the power output end of the second rotating driving member 428 is connected to the rotating bracket 429, the third vertical driving member 427 is installed on the rotating bracket 429, and the power output end of the third vertical driving member 427 is connected to the second adsorption member 420a, so that the second adsorption member 420a adsorbs the spring piece of the first cut block 423 or the second cut block 425 to the rotating shaft in the accommodating groove 120a.

[0067] In this embodiment, the second adsorption member 420a is a suction cup, and the second rotary drive member 428 drives the rotating bracket 429 to rotate, so as to drive the third vertical drive member 427 and the second adsorption member 420a to rotate, and the third vertical drive member 427 drives the second adsorption member 420a to move in the vertical direction, so that the second adsorption member 420a adsorbs the spring sheet on the first block 423 or the second block 425 to the rotating shaft in the receiving groove 120a to complete the assembly of the spring sheet. Further, the third vertical drive member 427 and the second rotary drive member 428 are motors or cylinders. Furthermore, in order to improve the efficiency of adsorbing the spring pieces on the first block and the second block, the number of the third vertical driving members 427 and the second adsorption members 420a is two, and the two third vertical driving members 427 are respectively installed on the opposite sides of the rotating bracket 429, and the two second adsorption members 420a are respectively connected to the power output ends of the corresponding third vertical driving members 427. When one of the second adsorption members 420a adsorbs the spring piece on the first block and rotates it above the rotating shaft, the other second adsorption member 420a is located on the second block to adsorb the spring piece on the second block. When the second adsorption member 420a on the rotating shaft assembles the spring piece, it rotates so that the other second adsorption member 420a rotates above the rotating shaft. In this way, the two second adsorption members 420a can continuously assemble the spring pieces on the first block or the second block on the rotating shaft during rotation, thereby improving the assembly efficiency of the spring pieces.

[0068] like Figure 6 As shown, in one embodiment, the fourth feeding assembly 520 includes a sixth bracket 521, a fourth vertical driving member 522, a fourth horizontal driving member 523, a fourth cylinder 524 and two second clamps 525, the sixth bracket 521 is installed on the mounting frame body 122, the fourth horizontal driving member 523 is installed on the sixth bracket 521, the power output end of the fourth horizontal driving member 523 is connected to the fourth vertical driving member 522, the power output end of the fourth vertical driving member 522 is connected to the fourth cylinder 524, and the power output end of the fourth cylinder 524 is respectively connected to the two second clamps 525 to make the two second clamps 525 approach or move away from each other.

[0069] In this embodiment, the fourth vertical driving member 522 drives the second clamping plate 525 to move in the vertical direction, and the fourth horizontal driving member 523 drives the second clamping plate 525 to move in the horizontal direction, so that the second clamping plate 525 moves to the discharge port of the fourth loading tray 510, and the fourth cylinder 524 drives the two second clamping plates 525 to move closer to each other to clamp the cam, and then the fourth horizontal driving member 523 and the fourth vertical driving member 522 drive the second clamping plate 525 to move above the receiving groove 120a, and the fourth cylinder 524 drives the two second clamping plates 525 to move away from each other to install the cam into the rotating shaft on the receiving groove 120a. Further, the fourth vertical driving member 522 and the fourth horizontal driving member 523 are motors or cylinders.

[0070] like Figure 7 As shown, in one embodiment, the fifth feeding assembly 620 includes a seventh bracket 621, a fifth vertical driving member 622, a fifth horizontal driving member 623, a fifth cylinder 624 and two third clamps 625, the seventh bracket 621 is installed on the mounting frame body 122, the fifth horizontal driving member 623 is installed on the seventh bracket 621, the power output end of the fifth horizontal driving member 623 is connected to the fifth vertical driving member 622, the power output end of the fifth vertical driving member 622 is connected to the fifth cylinder 624, and the power output end of the fifth cylinder 624 is respectively connected to the two third clamps 625 to make the two third clamps 625 approach or move away from each other.

[0071] In this embodiment, after the rotating shaft is installed in the cam, the concave wheel needs to be assembled so that the cam and the concave wheel cooperate with each other, the fifth vertical driving member 622 drives the third clamping plate 625 to move in the vertical direction, and the fifth horizontal driving member 623 drives the third clamping plate 625 to move in the horizontal direction so that the third clamping plate 625 can move to the fifth loading tray 610 and the receiving groove 120a, and the fifth cylinder 624 drives the two third clamping plates 625 to move away from or close to each other so that the two third clamping plates 625 can clamp or put down the concave wheel, and then clamp the concave wheel from the discharge port of the fifth loading tray 610 to the rotating shaft on the receiving groove 120a. Further, the fifth vertical driving member 622 and the fifth horizontal driving member 623 are motors or cylinders.

[0072] like Figure 1 and Figure 8As shown, in one embodiment, the assembly device 10 for the notebook shaft further includes a shaft blanking mechanism 700, the shaft blanking mechanism 700 includes a clamping assembly 710 and a code disc assembly 720, the clamping assembly 710 is installed on the machine 110, the code disc assembly 720 includes a moving module 721, a support frame 722, an empty disc bracket 723 and a full disc bracket 724, the support frame 722 is installed on the machine 110, the empty disc bracket 723 and the full disc bracket 724 are both installed on the support frame 722, and the empty disc bracket 723 is arranged opposite to the full disc bracket 724, and the moving module 721 is installed on the machine 110;

[0073] The moving module 721 is used to move the tray on the empty tray support 723 to the support frame 722, and move the tray on the support frame 722 to the full tray support 724, and the clamping assembly 710 is used to clamp the rotating shaft on the accommodating groove 120a to the tray on the support frame 722.

[0074] It can be understood that after the rotating shaft is assembled with friction plates, spring plates, cams and concave wheels in sequence, the rotating shaft needs to be assembled into the tray to enter the next process. In this embodiment, the empty tray bracket 723 is used to place the empty tray, and the full tray bracket 724 is used to place the tray filled with rotating shafts. The empty tray bracket 723 and the full tray bracket 724 are located on both sides of the support frame 722. First, the action end of the moving module 721 passes through the support frame 722 to remove the empty tray on the empty tray bracket 723. The support frame 722 is provided with a transfer point. The moving module 721 drives the empty tray to move to the transfer point. At this time, the clamping assembly 710 moves to clamp the rotating shaft on the accommodating groove 120a and place it in the empty tray on the transfer point. The clamping assembly 710 repeats multiple movements to fill the empty tray with rotating shafts. At this time, the moving module 721 starts to move the tray on the transfer point to the full tray bracket 724 to complete the storage and unloading operation of the rotating shaft.

[0075] like Figure 8 As shown, in one embodiment, the moving module 721 includes a transverse driving member 7211 and a jacking driving member 7212, the transverse driving member 7211 is installed on the machine 110, and the power output end of the transverse driving member 7211 is connected to the jacking driving member 7212, so that the action end of the jacking driving member 7212 moves on the support frame 722. In this embodiment, the transverse driving member 7211 drives the jacking driving member 7212 to move in the horizontal direction, and the action end of the jacking driving member 7212 moves in the vertical direction to remove the empty tray from the empty tray bracket 723, and move the tray filled with the rotating shaft to the full tray bracket 724, so as to stack the push trays into the full tray bracket 724.

[0076] like Figure 8 As shown, in one embodiment, the code disc assembly 720 also includes a first blocking member 722, and the first blocking member 722 includes a sixth cylinder and a first blocking plate. The sixth cylinder is installed on the outside of the empty disc bracket 723, and the power output end of the sixth cylinder is connected to the first blocking plate. The sixth cylinder is used to drive the first blocking plate to extend into or out of the empty disc bracket 723 so that the trays on the empty disc bracket 723 can be sequentially lowered.

[0077] In this embodiment, empty trays are sequentially stacked on the empty tray support 723 , and the first blocking member 722 cooperates with the moving module 721 to sequentially remove the empty trays on the empty tray support 723 . Specifically, the sixth cylinder is installed on the outside of the empty tray bracket 723, and the sixth cylinder drives the first baffle plate to move. When the first baffle plate is in the initial position, it abuts against the peripheral edge of the empty tray at the bottom. When the acting end of the jacking drive member 7212 passes through the empty tray bracket 723 and abuts against the empty tray at the bottom, the sixth cylinder drives the first baffle plate to move so that the first baffle plate no longer abuts against the empty tray. At this time, the jacking drive member 7212 drives the empty tray to move downward. When the second-to-last empty tray moves to be opposite to the first baffle plate, the jacking drive member 7212 stops moving. At this time, the sixth cylinder drives the first baffle plate to move to insert the first baffle plate between the bottom empty tray and the second-to-last empty tray to provide support for the empty tray. Then the jacking drive member 7212 continues to move to take out the bottom empty tray, completing the empty tray removal operation. Furthermore, in order to make the first blocking member 722 support the empty tray more stably, there are two first blocking members 722 , and the two first blocking members 722 are located on opposite sides of the bottom of the empty tray support 723 .

[0078] like Figure 8 As shown, in one embodiment, the code disc assembly 720 includes a second blocking member 723, and the second blocking member 723 includes a seventh cylinder and a second blocking plate. The seventh cylinder is installed on the outside of the full disc bracket 724, and the power output end of the seventh cylinder is connected to the second blocking plate. The seventh cylinder is used to drive the second blocking plate to extend into or out of the full disc bracket 724 so that the trays on the full disc bracket 724 are stacked sequentially.

[0079] In this embodiment, the second blocking member 723 cooperates with the moving module 721 to stack the pallets filled with rotating shafts at the transfer point into the full tray bracket 724. The seventh cylinder is installed on the outside of the full tray bracket 724, and the power output end of the seventh cylinder is connected to the second blocking plate, so that the seventh cylinder drives the second blocking plate to extend into or out of the full tray bracket 724, thereby completing the stacking operation of the pallets. Furthermore, the number of the second blocking members 723 is two, and the two second blocking members 723 are installed on opposite sides of the bottom of the full tray bracket 724 to make the support effect of the pallets more stable. Among them, the stacking of pallets on the full tray bracket 724 and the removal of pallets on the empty tray bracket 723 are the same principle, which will not be repeated here.

[0080] In one embodiment, the clamping assembly 710 includes an eighth bracket 711, a sixth vertical driving member 712, a sixth horizontal driving member 713, an eighth cylinder 714 and two fourth clamps 715, the eighth bracket 711 is installed on the machine 110, the sixth horizontal driving member 713 is installed on the eighth bracket 711, the power output end of the sixth horizontal driving member 713 is connected to the sixth vertical driving member 712, the power output end of the sixth vertical driving member 712 is connected to the eighth cylinder 714, and the power output end of the eighth cylinder 714 is respectively connected to the two fourth clamps 715 to make the two fourth clamps 715 approach or move away from each other.

[0081] In this embodiment, the clamping assembly 710 moves to clamp the rotating shaft on the receiving groove 120a into the tray. Specifically, the sixth vertical driving member 712 drives the fourth clamping plate 715 to move in the vertical direction, the sixth horizontal driving member 713 drives the fourth clamping plate 715 to move in the horizontal direction, and the eighth cylinder 714 drives the two fourth clamping plates 715 to move closer to or away from each other to clamp or release the rotating shaft, thereby enabling the fourth clamping plate 715 to clamp the rotating shaft in the receiving groove 120a into the tray on the support frame 722. Further, the sixth vertical driving member 712 and the sixth horizontal driving member 713 are motors or cylinders.

[0082] It is understandable that the friction plate is connected to the rotating shaft by a square hole due to its structural design, and the spring plate, cam and concave wheel are connected to the rotating shaft by circular holes, so that the friction plate, spring plate, cam and concave wheel are sequentially connected to the rotating shaft. However, the square hole has directionality relative to the circular hole. When the slot in the square hole is not aligned with the rotating shaft, it is difficult for the friction plate to be accurately installed on the rotating shaft. The second loading tray 310 adopts vibration loading, resulting in inconsistent directions of the square holes of the friction plate at each outlet, which leads to low positioning accuracy. Therefore, in order to improve the accuracy of friction plate assembly, such as Figure 4As shown, in one embodiment, the friction plate feeding mechanism 300 also includes a positioning assembly 330, the positioning assembly 330 includes a ninth bracket 331, a rotating drive member 332, a mounting plate 333 and a calibration shaft 334, the ninth bracket 331 is arranged adjacent to the second feeding tray 310, the ninth bracket 331 is installed on the machine 110, the rotating drive member 332 is connected to the ninth bracket 331, the power output end of the rotating drive member 332 is connected to the mounting plate 333, the calibration shaft 334 is installed on the mounting plate 333, and the structure of the calibration shaft 334 is arranged in the same manner as the structure of the rotating shaft. In this embodiment, the rotating driving member 332 is installed on the ninth bracket 331, the power output end of the rotating driving member 332 is connected to the mounting plate 333, the calibration shaft 334 is installed on the mounting plate 333, and the calibration shaft 334 is arranged in the same structure as the rotating shaft. When the second loading tray 310 conveys the friction plate to the discharge port, the first adsorption member 324 adsorbs the friction plate and conveys the friction plate to the calibration shaft 334. At this time, the first adsorption member 324 presses the friction plate on the upper end of the calibration shaft 334, and the rotating driving member 332 drives the mounting plate 333 to rotate, thereby driving the friction plate to rotate together. When the friction plate is rotated until the square hole slot is aligned with the calibration shaft 334, the friction plate will pass through the calibration shaft 334 to complete the calibration operation. Since the structure of the rotating shaft is the same as that of the calibration shaft 334, and the orientation of the rotating shaft at this time is the same as that of the calibration shaft, that is, the square hole of the friction plate is also aligned with the rotating shaft. At this time, the friction plate is sucked by the first adsorption component 324 and transported to the top of the rotating shaft. When the first adsorption component 324 releases the friction plate, the friction plate can accurately fall into the rotating shaft, which makes the assembly of the friction plate more precise and avoids the problem of missing assembly due to falling of the friction plate during assembly.

[0083] Furthermore, the first adsorbing member 324 needs to be positioned on the calibration shaft 334 before adsorbing the friction plate to the rotating shaft, that is, the first adsorbing member 324 first adsorbs the friction plate to the calibration shaft 334 and then calibrates it before adsorbing the friction plate to the rotating shaft. In this way, the first adsorbing member 324 needs two steps to complete the assembly of the friction plate, resulting in a low efficiency of the friction plate assembly. Therefore, in order to improve the efficiency of the friction plate assembly, Figure 4As shown, in one embodiment, the first suction member 324 includes a first suction nozzle 3241 and a second suction nozzle 3242, and the first suction nozzle 3241 and the second suction nozzle 3242 are respectively installed at the power output end of the second vertical driving member 322, and there is a preset distance between the first suction nozzle 3241 and the second suction nozzle 3242. In this embodiment, the first suction nozzle 3241 and the second suction nozzle 3242 are both used to adsorb the friction plate, and the first suction nozzle 3241 and the second suction nozzle 3242 are arranged in a front-to-back interval, and there is a preset distance between the first suction nozzle 3241 and the second suction nozzle 3242, and the preset distance is the same as the distance between the calibration shaft 334 and the rotating shaft. When working, the first suction nozzle 3241 adsorbs the friction plate in the second loading tray 310 onto the calibration shaft 334, and the rotating driving member 332 drives the calibration shaft 334 to rotate to drive the friction plate to rotate, so that the square hole slot of the friction plate is aligned with the calibration shaft 334, and the friction plate can penetrate the calibration shaft 334. At the same time, the second horizontal driving member 323 and the second vertical driving member 322 jointly drive the first suction nozzle 3241 and the second suction nozzle 3242 to move, so that the second suction nozzle 3242 is located above the calibration shaft 334, and the first suction nozzle 3241 returns to the top of the second loading tray 310. When the second suction nozzle 3242 adsorbs the friction plate of the calibration shaft 334 to the rotating shaft in front, the first suction nozzle 3241 synchronously adsorbs the new friction plate to the calibration shaft 334. In this way, the first suction nozzle 3241 and the second suction nozzle 3242 cooperate with each other to continuously position and calibrate the friction plate and assemble it on the rotating shaft, thereby improving the assembly efficiency of the friction plate.

[0084] It is understandable that the friction plate, spring sheet, cam and concave wheel need to be coated with engine oil after assembly. The engine oil can reduce the friction between the friction plate, spring sheet, cam and concave wheel, thereby reducing the wear between the parts and extending the service life of the shaft. In the traditional technology, after the parts are assembled, the engine oil in the suction nozzle is squeezed onto the shaft manually, which is time-consuming and labor-intensive, resulting in low production efficiency. At the same time, since it is difficult to control the force of the manual extrusion in the suction nozzle, the volume of the engine oil squeezed out each time is inconsistent, which leads to the waste of engine oil and increases the production cost. Therefore, in order to solve the above problems, Figure 1 and Fig. 9As shown, in one embodiment, the rotating shaft assembly equipment also includes an oiling mechanism 800, and the oiling mechanism 800 includes a tenth bracket 810, a seventh vertical driving member 820, a rotating motor 830, an air pump 840 and an oiling valve 850. The tenth bracket 810 is arranged adjacent to the cam feeding mechanism 600, the tenth bracket 810 is installed on the machine 110, the seventh vertical driving member 820 is installed on the tenth bracket 810, the power output end of the seventh vertical driving member 820 is connected to the rotating motor 830, the power output end of the rotating motor 830 is connected to the oiling valve 850, the air pump 840 is installed on the tenth bracket 810, and the air pump 840 is communicated with the oiling valve 850. In this embodiment, after the cam is assembled on the rotating shaft, the rotating bracket body 121 is rotated to the oiling mechanism 800, and the seventh vertical driving member 820 drives the oiling valve 850 to move in the vertical direction to make the oiling valve 850 close to the rotating shaft. The rotating motor 830 drives the oiling valve 850 to rotate around the rotating shaft, so that the oiling valve 850 can be oiled at multiple positions of the rotating shaft, thereby making the oil coating more uniform. At the same time, the air pump 840 is connected to the oiling valve 850 through a pipeline, so that the air pump 840 squeezes the oiling valve 850. The program setting can ensure that the volume of oil squeezed out by the oiling valve 850 each time is consistent, thereby avoiding the waste of oil due to uneven squeezing each time, thereby reducing production costs.

[0085] Furthermore, the end of the oil injection valve 850 squeezes the oil out through the needle tube 852. However, the cross-section of the part where the needle tube 852 contacts the friction plate, spring sheet and other parts is small, and the friction plate, spring sheet and other parts are made of plastic material with low structural strength. When the needle tube 852 is driven by the rotary motor 830 to rotate, the contact force between the end of the needle tube 852 and the friction plate and spring sheet is large. There is a problem that the needle tube 852 can easily scratch the friction plate and spring sheet, thereby damaging the friction plate and spring sheet and affecting the use effect. Therefore, if Fig.10As shown, in one embodiment, the oil-point valve 850 includes an oil tank 851 and a needle tube 852, the needle tube 852 includes a quantitative oil outlet 852a and a variable horn oil outlet 852b, the quantitative oil outlet 852a is connected to the oil tank 851, the variable horn oil outlet 852b is connected to the quantitative oil outlet 852a, and the cross-section of the variable horn oil outlet 852b gradually increases from close to the quantitative oil outlet 852a to away from the quantitative oil outlet 852a. In this embodiment, the oil tank 851 is connected to the pressure pump, and the two ends of the quantitative oil outlet 852a are respectively connected to the oil tank 851 and the variable horn oil outlet 852b, the cross-section of the quantitative oil outlet 852a remains unchanged, and the variable horn oil outlet 852b gradually increases from one end close to the quantitative oil outlet 852a to the end away from the quantitative oil outlet 852a, so as to ensure the oil output while increasing the volume of the contact area between the variable horn oil outlet 852b and the friction plate and the spring. When the force of the rotating motor 830 remains unchanged, the pressure of the needle tube 852 on the friction plate and the spring is reduced by increasing the volume of the contact area between the variable horn oil outlet 852b and the friction plate and the spring, thereby avoiding the problem of damage to the friction plate and the spring.

[0086] It is understandable that during the assembly process, the friction plate, spring sheet, cam and concave wheel may fall off due to misalignment of the holes, which may cause the problem of missing rotation. Especially for the assembly that requires the assembly of multiple spring sheets, the problem of missing assembly is more likely to occur, so that the shaft cannot rotate when assembled on the keyboard and screen, that is, the shaft assembly has a low yield rate. Therefore, in order to improve the yield rate of the shaft assembly, such as Fig.11As shown, in one embodiment, the rotating shaft device also includes a height detection mechanism 900, and the height detection mechanism 900 includes an eleventh bracket 910, an eighth vertical drive member 920 and a height sensor 930. The eleventh bracket 910 is arranged adjacent to the cam feeding mechanism 600, the eleventh bracket 910 is installed on the machine 110, the eighth vertical drive member 920 is installed on the eleventh bracket 910, the power output end of the eighth vertical drive member 920 is connected to the height sensor 930, and the detection end of the height sensor 930 is arranged corresponding to the rotating shaft. In this embodiment, after the cam is assembled on the rotating shaft, that is, when all parts are assembled on the rotating shaft, the rotating bracket body 121 rotates to move the rotating shaft to the height detection mechanism 900. At this time, the eighth vertical driving member 920 drives the height sensor 930 to move in the vertical direction so that the detection end of the height sensor 930 is aligned with the rotating shaft. The height sensor 930 detects the height of the parts assembled on the rotating shaft. When the height detected by the height sensor 930 does not match the predetermined value, it indicates that there is a problem of missing or over-installing parts on the rotating shaft. At this time, the device generates an alarm to enable the staff to remove the wrongly assembled rotating shaft. Further, in order to improve the convenience of collecting defective rotating shaft assembly, the height detection mechanism also includes a collection box and a transfer robot. The collection box is installed on the machine, and the transfer robot is installed on the eleventh bracket. The transfer robot is used to transport the rotating shaft in the accommodating groove to the collection box. It can be understood that the height sensor is electrically connected to the transfer robot. When the height sensor senses that the height of the shaft does not match the predetermined value, it indicates that the assembled shaft is a defective product. At this time, the transfer robot moves to clamp the shaft in the receiving groove and transport it to the collection box for collection, so that the staff can centrally process the defective shafts, avoiding the need for the staff to take out the defective shafts every time, thereby improving production efficiency.

[0088] In the above-mentioned assembly device 10 for the notebook shaft, the conveyor frame 120 is provided with a receiving groove 120a, and the receiving groove 120a is used to receive the shaft. The mobile driving member 130 drives the conveyor frame 120 to sequentially pass through the shaft feeding mechanism 200, the friction plate feeding mechanism 300, the spring plate feeding mechanism 400, the cam feeding mechanism 500 and the concave wheel feeding mechanism 600. The first feeding assembly conveys the shaft in the first feeding to the receiving groove 120a, and the second feeding assembly 320 conveys the friction plate in the second feeding tray 310 to On the rotating shaft, the third feeding assembly 420 conveys the spring piece in the third loading tray 410 to the rotating shaft, the fourth feeding assembly 520 conveys the cam in the fourth loading tray 510 to the rotating shaft, and the fifth feeding assembly 620 conveys the concave wheel in the fifth loading tray 610 to the rotating shaft, so that the friction plate, spring piece, cam and concave wheel are sequentially mounted on the rotating shaft in the accommodating groove 120a, with a high degree of automation, improved production efficiency, and at the same time avoids the problem of missing or wrong assembly during manual assembly, thereby improving the assembly accuracy of the rotating shaft assembly.
