The whole process is automatically operated, the manual steps are reduced, the production efficiency is improved, the problems of missing and misassembling during manual assembly are avoided, and the assembly precision is improved. Further, the number of the friction plate feeding mechanisms 300 is two, which are 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 shaft feeding mechanism 200 and the elastic sheet feeding mechanism 400, and the second friction plate feeding mechanism 300 is located after the concave cam feeding mechanism 600, that is, the shaft needs to be assembled with two friction plates, so that the elastic sheet, the cam and the concave cam are clamped between the two friction plates.

The elastic sheet provides stable supporting force through elastic deformation.

[0055] The above-mentioned assembly equipment 10 for the notebook shaft, the conveying frame 120 is provided with a receiving groove 120a for receiving the shaft, the moving driver 130 drives the conveying frame 120 to sequentially pass through the shaft feeding mechanism 200, the friction plate feeding mechanism 300, the elastic sheet feeding mechanism 400, the cam feeding mechanism 500 and the concave cam feeding mechanism 600, the first feeding assembly 220 feeds the shaft in the first feeding tray 210 into the receiving groove 120a, the second feeding assembly 320 feeds the friction plate in the second feeding tray 310 onto the shaft, the third feeding assembly 420 feeds the elastic sheet in the third feeding tray 410 onto the shaft, the fourth feeding assembly 520 feeds the cam in the fourth feeding tray 510 onto the shaft, and the fifth feeding assembly 620 feeds the concave cam in the fifth feeding tray 610 onto the shaft, so that the friction plate, the elastic sheet, the cam and the concave cam are sequentially sleeved on the shaft in the receiving groove 120a.

[0056] like Figure 2 As shown, in one embodiment, the conveyor frame 120 includes a rotating support body 121 and a mounting frame body 122. The rotating support body 121 is mounted on the power output end of the moving drive member 130. The rotating 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 are arranged around the rotating support body 121. The moving drive member 130 is used to drive the rotating support body 121 to rotate. The receiving groove 120a is opened in the rotating support body 121. The mounting frame body 122 is fixedly connected to the machine base 110.

[0057] In this embodiment, the rotating support body 121 is circular. A rotating shaft feeding mechanism, a friction plate feeding mechanism 300, a spring plate feeding mechanism 400, a cam feeding mechanism 500, and a concave wheel feeding mechanism 600 are arranged around the rotating support body 121. A moving drive component 130 drives the rotating support body 121 to rotate, resulting in higher utilization of the internal assembly space and facilitating miniaturization of the equipment. A receiving groove 120a is formed in the rotating support body 121 so that the rotating shaft within the receiving groove passes sequentially through the friction plate feeding mechanism 300, the spring plate feeding mechanism 400, the cam feeding mechanism 500, and the concave wheel feeding mechanism 600, thereby allowing the friction plate, spring plate, cam, and concave wheel to be sequentially fitted onto the rotating shaft. Furthermore, the mounting frame body 122 is located above the rotating support body 121, and the mounting frame body 122 is fixedly connected to the machine base 110. The mounting frame body 122 provides a mounting 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 rotary drive 221, a rotary tray 222, a first bracket 223, a second bracket 224, a first vertical drive 225, a first horizontal drive 226, a first cylinder 227, and two first clamping plates 228. The first bracket 223 is mounted on the machine base 110. The first rotary drive 221 is connected to the first bracket 223. The rotary tray 222 is connected to the power output end of the first rotary drive 221. The rotary tray 222 has an embedding slot. The first rotary drive 221 drives the rotary tray 222 to rotate so that the embedding slot is connected to the material conveying channel of the first feeding tray 210.

[0059] The second bracket 224 is connected to the mounting bracket body 122. The first horizontal drive member 226 is mounted on the second bracket 224. The power output end of the first horizontal drive member 226 is connected to the first vertical drive member 225. The power output end of the first vertical drive member 225 is connected to the first cylinder 227. The power output end of the first cylinder 227 is connected to the two first clamping plates 228 respectively, so that the two first clamping plates 228 are closer to or further away from each other.

[0060] In this embodiment, the first feeding tray 210 is used to transport the rotating shaft. However, the rotating shaft transported by the first feeding tray 210 is placed horizontally. The rotating shaft needs to be rotated 90° so that it can be inserted into the receiving groove 120a. Specifically, when the rotating pallet 222 is in its initial position, the inserting slot of the rotating pallet 222 is connected to the conveying channel of the first feeding tray 210. After the first feeding tray 210 conveys the rotating shaft into the inserting slot, the first rotating drive member 221 drives the rotating pallet 222 to rotate, causing the rotating pallet 222 to rotate 90°. At this time, the rotating shaft changes from a horizontal setting to a vertical setting. The first horizontal drive member 226 indirectly drives the clamping plate to move horizontally, and the first vertical drive member 225 indirectly drives the clamping plate to move vertically, so that the two clamping plates are above the rotating pallet 222. The first cylinder 227 drives the two clamping plates to move closer to each other to clamp the rotating shaft. Then, the first vertical drive member 225 and the first horizontal drive member 226 drive the clamping plates to move above the receiving slot 120a. The first cylinder 227 drives the two clamping plates to move away from each other to place the rotating shaft into the receiving slot 120a. Finally, the two clamping plates are reset, completing the feeding operation of the rotating shaft. Furthermore, the first vertical drive member 225 and the first horizontal drive 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 drive member 322, a second horizontal drive member 323, and a first suction member 324. The third bracket 321 is connected to the mounting frame body 122. The second horizontal drive member 323 is mounted on the third bracket 321. The second vertical drive member 322 is connected to the power output end of the second horizontal drive member 323. The power output end of the second vertical drive member 322 is connected to the first suction member 324, so that the first suction member 324 adsorbs the friction plate of the second feeding tray 310 onto the rotating shaft in the receiving groove 120a.

[0062] In the embodiment, the first suction accessory 324 adopts a suction disc, because the material of the friction sheet is soft, and the clamping mode cannot conveniently and accurately sleeve the friction sheet into the rotating shaft. Specifically, the second horizontal driving member 323 drives the first suction accessory 324 to move in the horizontal direction, and the second vertical driving member 322 drives the first suction accessory 324 to move in the vertical direction, so that the first suction accessory 324 moves above the second feeding disc 310. After the first suction accessory 324 adsorbs the friction sheet, the second horizontal driving member 323 and the second vertical driving member 322 drive the first suction accessory 324 to move above the rotating shaft, so that the first suction accessory 324 sleeves the friction sheet into the rotating shaft.

[0063] As shown in the drawings, Figure 5 In one of the embodiments, the third feeding disc 410 is provided with a first feeding channel 411 and a second feeding channel 412, both of which are used for conveying the elastic sheets, and the directions of the elastic sheets in the first feeding channel 411 and the second feeding channel 412 are opposite. It can be understood that a plurality of elastic sheets need to be installed in the rotating shaft, and each elastic sheet has front and back surfaces, and the order of the installation of the adjacent two elastic sheets on the rotating shaft is opposite, so that the plurality of elastic sheets provide sufficient deformation for the rotating shaft, and thus the screen rotation function is more stable. In the embodiment, the first feeding channel 411 and the second feeding channel 412 are both used for conveying the elastic sheets, the front surface of the elastic sheet conveyed by the first feeding channel 411 faces upward, and the back surface of the elastic sheet conveyed by the second feeding channel 412 faces upward, so that the elastic sheet is more accurate and fast when being installed.

[0064] As shown in the drawings, Figure 5 In one of the embodiments, the third feeding assembly 420 includes a fourth support 421, a second air cylinder 422, a first cutting block 423, a third air cylinder 424, and a second cutting block 425. The fourth support 421 is installed on the machine table 110, the second air cylinder 422 is connected to the fourth support 421, the first cutting block 423 is connected to the power output end of the second air cylinder 422, the material groove of the first cutting block 423 is in communication with the first feeding channel 411, and the second air cylinder 422 drives the first cutting block 423 to convey the elastic sheet in the first feeding channel 411 to a predetermined position. In the embodiment, when the first cutting block 423 is in the initial position, the material groove of the first cutting block 423 is in communication with the first feeding channel 411. After the elastic sheet in the first feeding channel 411 enters the material groove of the first cutting block 423, the second air cylinder 422 drives the first cutting block 423 to move, so as to convey the elastic sheet to the predetermined position, so as to be adsorbed by the second suction accessory 420a, and the production efficiency is improved.

[0065] As shown in the drawings, Figure 5As shown, in one of the embodiments, the third cylinder 424 is connected to the fourth support 421, the second cutting block 425 is connected to the power output end of the third cylinder 424, the material groove of the second cutting block 425 is communicated with the second feeding channel 412, and the third cylinder 424 drives the second cutting block 425 to transport the bullet in the second feeding channel 412 to a preset position. In this embodiment, the third cylinder 424 drives the second cutting block 425 to move, so as to move the bullet on the second feeding channel 412 to a predetermined position, so as to be adsorbed by the second suction accessory 420a. Through the cooperation of the first cutting block 423 and the second cutting block 425, the uninterrupted feeding of the bullets in two different directions can be realized, and the production efficiency is further improved.

[0066] As shown, Figure 5 As shown, in one of the embodiments, the third feeding assembly 420 further comprises a fifth support 426, a third vertical driving member 427, a second rotary driving member 428, a rotating support 429 and a second suction accessory 420a, the fifth support 426 is installed on the mounting body 122, the second rotary driving member 428 is connected to the fifth support 426, the power output end of the second rotary driving member 428 is connected to the rotating support 429, the third vertical driving member 427 is installed on the rotating support 429, and the power output end of the third vertical driving member 427 is connected to the second suction accessory 420a, so that the second suction accessory 420a adsorbs the bullet of the first cutting block 423 or the second cutting 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, thereby driving the third vertical drive member 427 and the second adsorption member 420a to rotate. The third vertical drive member 427 drives the second adsorption member 420a to move vertically, so that the second adsorption member 420a adsorbs the spring piece on the first cut block 423 or the second cut block 425 onto the rotating shaft in the receiving groove 120a, thereby completing the assembly of the spring piece. Further, the third vertical drive member 427 and the second rotary drive member 428 are motors or cylinders. Furthermore, to improve the efficiency of adsorbing the spring pieces on the first and second cut blocks, there are two third vertical drive members 427 and two second adsorption members 420a. The two third vertical drive members 427 are respectively installed on opposite sides of the rotating bracket 429, and the two second adsorption members 420a are respectively connected to the power output end of the corresponding third vertical drive member 427. When one of the second adsorption members 420a adsorbs the spring piece on the first cut block and rotates it above the rotating shaft, the other second adsorption member 420a is located on the second cut block to adsorb the spring piece on the second cut block. When the second adsorption member 420a on the rotating shaft assembles the spring piece and rotates, the other second adsorption member 420a rotates to the top of the rotating shaft. In this way, the two second adsorption members 420a can continuously assemble the spring pieces on the first or second cut block onto the rotating shaft when rotating, 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 drive member 522, a fourth horizontal drive member 523, a fourth cylinder 524, and two second clamping plates 525. The sixth bracket 521 is mounted on the mounting frame body 122, the fourth horizontal drive member 523 is mounted on the sixth bracket 521, the power output end of the fourth horizontal drive member 523 is connected to the fourth vertical drive member 522, the power output end of the fourth vertical drive member 522 is connected to the fourth cylinder 524, and the power output end of the fourth cylinder 524 is connected to the two second clamping plates 525 respectively, so that the two second clamping plates 525 move closer to or further away from each other.

[0069] In this embodiment, the fourth vertical drive member 522 drives the second clamping plate 525 to move vertically, and the fourth horizontal drive member 523 drives the second clamping plate 525 to move horizontally, so that the second clamping plate 525 moves to the discharge port of the fourth feeding tray 510. The fourth cylinder 524 drives the two second clamping plates 525 to move closer to each other to clamp the cam. Then, the fourth horizontal drive member 523 and the fourth vertical drive member 522 drive the second clamping plate 525 to move above the receiving groove 120a. The fourth cylinder 524 drives the two second clamping plates 525 to move away from each other to load the cam into the rotating shaft on the receiving groove 120a. Further, the fourth vertical drive member 522 and the fourth horizontal drive 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 drive member 622, a fifth horizontal drive member 623, a fifth cylinder 624, and two third clamping plates 625. The seventh bracket 621 is mounted on the mounting frame body 122, the fifth horizontal drive member 623 is mounted on the seventh bracket 621, the power output end of the fifth horizontal drive member 623 is connected to the fifth vertical drive member 622, the power output end of the fifth vertical drive member 622 is connected to the fifth cylinder 624, and the power output end of the fifth cylinder 624 is connected to the two third clamping plates 625 respectively, so that the two third clamping plates 625 move closer to or further away from each other.

[0071] In this embodiment, after the rotating shaft is fitted with the cam, a concave wheel needs to be assembled so that the cam and the concave wheel cooperate with each other. The fifth vertical drive member 622 drives the third clamping plate 625 to move vertically, and the fifth horizontal drive member 623 drives the third clamping plate 625 to move horizontally, so that the third clamping plate 625 can move to the fifth feeding tray 610 and the receiving groove 120a. The fifth cylinder 624 drives the two third clamping plates 625 to move away from or closer to each other, so that the two third clamping plates 625 can clamp or release the concave wheel, thereby clamping the concave wheel from the discharge port of the fifth feeding tray 610 to the rotating shaft on the receiving groove 120a. Further, the fifth vertical drive member 622 and the fifth horizontal drive member 623 are motors or cylinders.

[0072] like Figure 1 and Figure 8As shown, in one embodiment, the assembly equipment 10 for the laptop hinge further includes a hinge unloading mechanism 700. The hinge unloading mechanism 700 includes a clamping component 710 and a code disk component 720. The clamping component 710 is mounted on the machine base 110. The code disk component 720 includes a moving module 721, a support frame 722, an empty disk support 723, and a full disk support 724. The support frame 722 is mounted on the machine base 110. The empty disk support 723 and the full disk support 724 are both mounted on the support frame 722, and the empty disk support 723 and the full disk support 724 are arranged opposite to each other. The moving module 721 is mounted on the machine base 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. The clamping assembly 710 is used to clamp the rotating shaft on the receiving groove 120a to the tray on the support frame 722.

[0074] Understandably, after the rotating shaft is sequentially assembled with friction plates, springs, cams, and concave wheels, it needs to be installed into a tray to proceed to the next process. In this embodiment, the empty tray support 723 is used to place an empty tray, and the full tray support 724 is used to place a tray filled with rotating shafts. The empty tray support 723 and the full tray support 724 are located on both sides of the support frame 722. First, the actuating end of the moving module 721 passes through the support frame 722 to remove the empty tray from the empty tray support 723. The support frame 722 has a transfer point. The moving module 721 moves the empty tray to the transfer point. At this time, the clamping component 710 moves to clamp the rotating shaft on the receiving slot 120a and place it into the empty tray at the transfer point. The clamping component 710 repeats its movement multiple times to fill the empty tray with rotating shafts. Then, the moving module 721 is activated to move the tray at the transfer point to the full tray support 724, completing the storage and unloading operation of the rotating shafts.

[0075] like Figure 8 As shown, in one embodiment, the moving module 721 includes a lateral drive 7211 and a lifting drive 7212. The lateral drive 7211 is mounted on the machine base 110, and its power output end is connected to the lifting drive 7212, so that the actuating end of the lifting drive 7212 moves on the support frame 722. In this embodiment, the lateral drive 7211 drives the lifting drive 7212 to move horizontally, and the actuating end of the lifting drive 7212 moves vertically to remove the empty tray from the empty tray support 723 and move the tray filled with rotating shafts to the full tray support 724, so that the pusher trays are stacked into the full tray support 724.

[0076] likeFigure 8 As shown, in one embodiment, the encoder assembly 720 further includes a first blocking member 722, which includes a sixth cylinder and a first blocking plate. The sixth cylinder is mounted on the outside of the empty tray support 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 tray support 723 so that the trays on the empty tray support 723 descend sequentially.

[0077] In this embodiment, empty trays are stacked sequentially on the empty tray support 723. The first blocking member 722 cooperates with the moving module 721 to remove the empty trays sequentially from the empty tray support 723. Specifically, the sixth cylinder is installed on the outside of the empty tray support 723. The sixth cylinder drives the first blocking plate to move. In the initial position, the first blocking plate abuts against the periphery of the bottom empty tray. When the actuating end of the lifting drive 7212 passes through the empty tray support 723 and abuts against the bottom empty tray, the sixth cylinder drives the first blocking plate to move so that the first blocking plate no longer abuts against the empty tray. At this time, the lifting drive 7212 drives the empty tray to move downward. When the second to last empty tray moves to be opposite the first blocking plate, the lifting drive 7212 stops moving. At this time, the sixth cylinder drives the first blocking plate to move so that the first blocking plate is inserted between the bottom empty tray and the second to last empty tray to provide support for the empty tray. Then the lifting drive 7212 continues to move to remove the bottom empty tray, completing the removal operation of the empty tray. Furthermore, in order to make the first blocking member 722 provide more stable support for the empty tray, 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 encoder assembly 720 includes a second blocking member 723, which includes a seventh cylinder and a second blocking plate. The seventh cylinder is mounted on the outside of the full tray support 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 tray support 724 so that the trays on the full tray support 724 are stacked sequentially.

[0079] In the embodiment, the second blocking member 723 cooperates with the moving module 721 to place the tray stack filled with the shafts at the transfer point into the full tray support 724. The seventh cylinder is installed outside the full tray support 724. The power output end of the seventh cylinder is connected with the second blocking plate to drive the second blocking plate to extend into or out of the full tray support 724, thereby completing the stacking operation of the tray. Further, the number of the second blocking member 723 is two. The two second blocking members 723 are installed on the opposite sides of the bottom of the full tray support 724 to make the support effect of the tray more stable. The principle of stacking the tray in the full tray support 724 is the same as that of taking out the tray from the empty tray support 723, which will not be described here.

[0080] In one of the embodiments, the gripping assembly 710 includes an eighth support 711, a sixth vertical driving member 712, a sixth horizontal driving member 713, an eighth cylinder 714, and two fourth clamping plates 715. The eighth support 711 is installed on the machine table 110. The sixth horizontal driving member 713 is installed on the eighth support 711. The power output end of the sixth horizontal driving member 713 is connected with the sixth vertical driving member 712. The power output end of the sixth vertical driving member 712 is connected with the eighth cylinder 714. The power output end of the eighth cylinder 714 is connected with the two fourth clamping plates 715 respectively to make the two fourth clamping plates 715 close to or away from each other.

[0081] In the embodiment, the gripping assembly 710 moves to clamp the shaft on the accommodation 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. The eighth cylinder 714 drives the two fourth clamping plates 715 to close to or away from each other to clamp or release the shaft, thereby realizing that the fourth clamping plate 715 clamps the shaft in the accommodation 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 can be understood that the friction plate is sleeved on the shaft through the square hole due to the structural design. The elastic sheet, the cam, and the concave wheel are all sleeved on the shaft through the circular hole, so that the friction plate, the elastic sheet, the cam, and the concave wheel are sequentially sleeved on the shaft. However, the square hole has directionality relative to the circular hole. When the slot in the square hole is not aligned with the shaft, the friction plate is difficult to be accurately installed on the shaft. The second feeding disc 310 adopts vibration feeding, which causes the directions of the square holes of the friction plates at each discharge port to be inconsistent, so that the positioning accuracy is low. Therefore, in order to improve the assembly accuracy of the friction plate, the second feeding disc 310 is designed as follows. Figure 4As shown, in one embodiment, the friction plate feeding mechanism 300 further includes a positioning component 330. The positioning component 330 includes a ninth bracket 331, a rotation drive 332, a mounting plate 333, and a calibration shaft 334. The ninth bracket 331 is disposed adjacent to the second feeding tray 310 and is mounted on the machine base 110. The rotation drive 332 is connected to the ninth bracket 331, and the power output end of the rotation drive 332 is connected to the mounting plate 333. The calibration shaft 334 is mounted on the mounting plate 333, and the structure of the calibration shaft 334 is the same as that of the rotating shaft. In this embodiment, the rotation drive 332 is mounted on the ninth bracket 331, and the power output end of the rotation drive 332 is connected to the mounting plate 333. The calibration shaft 334 is mounted on the mounting plate 333, and the calibration shaft 334 has the same structure as the rotating shaft. When the second feeding plate 310 conveys the friction plate to the discharge port, the first adsorption member 324 adsorbs the friction plate and conveys it to the calibration shaft 334. At this time, the first adsorption member 324 presses the friction plate against the upper end of the calibration shaft 334, and the rotation drive 332 drives the mounting plate 333 to rotate, thereby causing the friction plate to rotate as well. When the friction plate rotates to align with the square hole slot of 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 is the same as that of the calibration shaft, the square hole of the friction plate is also aligned with the rotating shaft. At this time, the first suction member 324 picks up the friction plate and transports it to the top of the rotating shaft. When the first suction member 324 releases the friction plate, the friction plate can fall accurately into the rotating shaft. This makes the assembly of the friction plate more precise and avoids the problem of the friction plate falling off during assembly and being missing.

[0083] Furthermore, before the first adsorption member 324 adsorbs the friction plate onto the rotating shaft, it needs to be positioned on the calibration shaft 334. That is, the first adsorption member 324 first adsorbs the friction plate onto the calibration shaft 334, calibrates it, and then adsorbs the friction plate onto the rotating shaft. Thus, the first adsorption member 324 requires two steps to complete the assembly of the friction plate, resulting in low assembly efficiency. Therefore, to improve the assembly efficiency of the friction plate, such as... Figure 4As shown, in one of the embodiments, the first suction accessory 324 includes a first suction nozzle 3241 and a second suction nozzle 3242, which are respectively installed on the power output end of the second vertical driving member 322, and there is a preset interval 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 for suctioning the friction plate, and the first suction nozzle 3241 and the second suction nozzle 3242 are arranged in front of and behind each other, and there is a preset interval between the first suction nozzle 3241 and the second suction nozzle 3242, which is the same as the interval between the calibration shaft 334 and the rotating shaft. In operation, the first suction nozzle 3241 sucks the friction plate in the second feeding disc 310 to 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 groove of the friction plate is aligned with the calibration shaft 334, and then the friction plate can be inserted into the calibration shaft 334. At this 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 above the second feeding disc 310. When the second suction nozzle 3242 sucks the friction plate of the calibration shaft 334 to the rotating shaft in front, the first suction nozzle 3241 synchronously sucks the new friction plate to the calibration shaft 334. In this way, the first suction nozzle 3241 and the second suction nozzle 3242 can continuously position, calibrate and assemble the friction plate on the rotating shaft, thereby improving the assembly efficiency of the friction plate.

[0084] It can be understood that the assembled friction plate, spring, cam and concave wheel need to be coated with machine oil, which can reduce the friction between the friction plate, spring, cam and concave wheel, thereby reducing the wear between the parts, prolonging the service life of the rotating shaft. In the traditional technology, the machine oil in the suction nozzle is squeezed onto the rotating shaft by manual operation after the assembly of each part is completed, which is time-consuming and laborious, resulting in low production efficiency. At the same time, since the strength of the manual operation in the suction nozzle is difficult to control, the volume of the squeezed machine oil is not consistent each time, which leads to the waste of machine oil and increases the production cost. Therefore, in order to solve the above problems, such as Figure 1 and Figure 9As shown, in one of the embodiments, the shaft assembling device further comprises an oiling mechanism 800, which comprises a tenth bracket 810, a seventh vertical driving member 820, a rotary motor 830, an air pump 840 and an oiling valve 850. The tenth bracket 810 is arranged adjacent to the concave wheel feeding mechanism 600 and is mounted on the machine table 110. The seventh vertical driving member 820 is mounted on the tenth bracket 810. The power output end of the seventh vertical driving member 820 is connected with the rotary motor 830. The power output end of the rotary motor 830 is connected with the oiling valve 850. The air pump 840 is mounted on the tenth bracket 810 and is connected in communication with the oiling valve 850. In this embodiment, after the concave wheel is assembled on the shaft, the rotary bracket body 121 is rotated to the oiling mechanism 800. The seventh vertical driving member 820 drives the oiling valve 850 to move in the vertical direction so as to make the oiling valve 850 close to the shaft. The rotary motor 830 drives the oiling valve 850 to rotate around the shaft, so that the oiling valve 850 can perform oiling at multiple positions of the shaft, thereby making the oiling more uniform. At the same time, the air pump 840 is connected in communication with the oiling valve 850 through a pipeline, so that the air pump 840 extrudes the oiling valve 850. The volume of the oil extruded by the oiling valve 850 each time can be ensured to be consistent through program setting, thereby avoiding the waste problem of the oil due to the non-uniform extrusion each time and reducing the production cost.

[0085] Further, the end of the oiling valve 850 extrudes the oil outside through a needle tube 852. However, since the cross section of the part in contact with the friction plate and the elastic sheet and other parts of the needle tube 852 is small, the friction plate, the elastic sheet and other parts are made of plastic material and have low structural strength. When the needle tube 852 is rotated under the driving of the rotary motor 830, the contact force between the end of the needle tube 852 and the friction plate and the elastic sheet is large. The needle tube 852 is prone to scratch the friction plate and the elastic sheet, thereby damaging the friction plate and the elastic sheet and affecting the use effect. Therefore, as shown in FIG. 8, the needle tube 852 is connected with the air pump 840 through a pipeline, so that the air pump 840 extrudes the needle tube 852. The volume of the oil extruded by the needle tube 852 each time can be ensured to be consistent through program setting, thereby avoiding the waste problem of the oil due to the non-uniform extrusion each time and reducing the production cost. Figure 10As shown, in one embodiment, the oil injection valve 850 comprises an oil reservoir 851 and a needle tube 852, the needle tube 852 comprises a constant oil injection part 852a and a variable horn oil injection part 852b, the constant oil injection part 852a is in communication with the oil reservoir 851, the variable horn oil injection part 852b is in communication with the constant oil injection part 852a, and the cross section of the variable horn oil injection part 852b gradually increases from the constant oil injection part 852a to the far end of the constant oil injection part 852a. In this embodiment, the oil reservoir 851 is in communication with the pressure pump, the two ends of the constant oil injection part 852a are in communication with the oil reservoir 851 and the variable horn oil injection part 852b respectively, the cross section of the constant oil injection part 852a remains unchanged, and the cross section of the variable horn oil injection part 852b gradually increases from the end close to the constant oil injection part 852a to the end far from the constant oil injection part 852a. This ensures the oil injection amount, and also increases the volume of the part of the variable horn oil injection part 852b in contact with the friction plate and the elastic plate. Under the condition that the force of the rotating motor 830 remains unchanged, by increasing the volume of the part of the variable horn oil injection part 852b in contact with the friction plate and the elastic plate, the pressure of the needle tube 852 on the friction plate and the elastic plate is reduced, thereby avoiding the problem of damage to the friction plate and the elastic plate.

[0086] It can be understood that during the assembly process of the friction plate, the elastic plate, the convex cam and the concave cam, there is a problem of falling due to misalignment of the hole position, thereby causing the problem of missing rotation. Especially for the assembly of multiple elastic plates, the problem of missing assembly is more likely to occur, so that the rotation shaft assembly cannot play a rotating effect when assembled in the keyboard and the screen, that is, the rotation shaft assembly has the problem of low yield. Therefore, in order to improve the yield of the rotation shaft assembly, such as Figure 11As shown, in one of the embodiments, the rotating shaft device further comprises a height detection mechanism 900, which comprises an eleventh support 910, an eighth vertical driving member 920 and a height sensor 930. The eleventh support 910 is arranged adjacent to the concave wheel feeding mechanism 600 and is mounted on the machine table 110. The eighth vertical driving member 920 is mounted on the eleventh support 910, and the power output end of the eighth vertical driving member 920 is connected with the height sensor 930. The detection end of the height sensor 930 is arranged corresponding to the rotating shaft. In this embodiment, after the rotating shaft is assembled with the concave wheel, i.e. after all the parts are assembled, the rotating support 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 overloading of the parts on the rotating shaft at this time. At this time, the device generates an alarm to make the staff take down the rotating shaft with assembly error. Further, in order to improve the convenience of collecting the rotating shaft assembly defective products, the height detection mechanism further comprises a collection box and a transfer manipulator. The collection box is mounted on the machine table, and the transfer manipulator is mounted on the eleventh support. The transfer manipulator is used to transport the rotating shaft in the accommodation groove to the collection box. It can be understood that the height sensor is electrically connected with the transfer manipulator. When the height sensor senses that the height of the rotating shaft does not match the predetermined value, it indicates that the assembled rotating shaft is a defective product at this time. At this time, the transfer manipulator moves to clamp and transport the rotating shaft in the accommodation groove to the collection box for collection, so that the staff can centrally process the rotating shaft defective products, avoiding the operation of taking out the rotating shaft defective products each time, and improving the production efficiency.
