Description

Technical Field

[0001] The utility model relates to the technical field of glass processing, in particular to a polishing machine. Background Art

[0002] With the development of technology, smartphones are becoming increasingly popular. To enhance the aesthetics of mobile phones, a 3D glass cover is often installed on the side with the screen. When manufacturing a 3D glass cover, the glass sheet is usually first placed in a heat bending machine to bend it into a 3D glass cover. Then, a polishing machine is used to polish the convex surface (front side) of the 3D glass cover to ensure the aesthetics of the 3D glass cover.

[0003] Existing polishing machines generally include a polishing mechanism, a jig plate mechanism, two half-axes, two flip drive mechanisms, two cylinders, and a loading and unloading mechanism. The polishing mechanism, jig plate mechanism, and loading and unloading mechanisms are arranged sequentially from bottom to top. The jig plate mechanism is provided with jigs at the top and bottom ends, respectively. The two flip drive mechanisms are arranged opposite each other on the left and right sides, with the jig plate mechanism located between the two flip drive mechanisms. One end of each of the two half-axes is connected to either side of the jig plate mechanism, and the other ends of each of the two half-axes are connected to the two flip drive mechanisms. Two cylinders correspond to the two flip drive mechanisms, and the output ends of the two cylinders are connected to the two flip drive mechanisms. The loading and unloading mechanism allows a 3D glass cover to be placed on the jig at the top or bottom of the jig plate mechanism, and after polishing, the 3D glass cover can be removed from the jig at the top or bottom of the jig plate. The two half-axles are driven to rotate by the two flipping drive mechanisms, thereby driving the jig plate mechanism to flip, so that the 3D glass cover plate on the jig at the top of the jig plate mechanism is opposite to the polishing mechanism or the 3D glass cover plate on the jig at the bottom of the jig plate mechanism is opposite to the polishing mechanism, and the two flipping drive mechanisms are driven up and down by the two cylinders, thereby driving the jig plate mechanism to move up and down by the two half-axles, so that the front side of the 3D glass cover plate on the jig at the top of the jig plate mechanism is in contact with or separated from the polishing mechanism, or the front side of the 3D glass cover plate on the jig at the top of the jig plate mechanism is in contact with or separated from the polishing mechanism, and the front side of the 3D glass cover plate is brought into contact with the polishing mechanism, thereby the polishing mechanism can polish the front side of the 3D glass cover plate.

[0004] Due to factors such as unstable air pressure and difference in air volume, the two cylinders often move out of sync, making it impossible to ensure the synchronization of the two flip drive mechanisms and the up and down movement of the two half-axes. As a result, the jigs at the top and bottom of the jig plate mechanism are prone to tilting. After the 3D glass cover is placed on the jig through the loading and unloading mechanism, the position of the 3D glass cover will deviate, resulting in the jig being unable to stably fix the 3D glass cover, reducing the stability of the 3D glass cover and reducing the polishing efficiency. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the utility model provides a polishing machine. After the 3D glass cover plate is placed on the jig through the loading and unloading mechanism, the position of the 3D glass cover plate will not deviate, so that the jig can stably fix the 3D glass cover plate, thereby improving the stability of the 3D glass cover plate and improving the polishing efficiency.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A polishing machine comprises a polishing mechanism, a jig plate mechanism, two half-axes, two flip drive mechanisms and a loading and unloading mechanism, wherein the polishing mechanism, jig plate mechanism and loading and unloading mechanism are sequentially arranged from bottom to top, the top and bottom ends of the jig plate mechanism are respectively provided with jigs, the two flip drive mechanisms are arranged opposite to each other on the left and right sides, the jig plate mechanism is located between the two flip drive mechanisms, one end of the two half-axes is respectively connected to the two sides of the jig plate mechanism, the other ends of the two half-axes are respectively connected to the two flip drive mechanisms, and also comprises two lifting drive mechanisms, the two lifting drive mechanisms respectively correspond to the two flip drive mechanisms, the lifting drive mechanism comprises a lifting mounting plate, a fixing plate, a lifting motor The lifting motor is used to drive the lifting screw to rotate, and the lifting nut is engaged with the lifting screw thread and is connected to the corresponding flip driving mechanism.

[0008] The beneficial effects of the present invention are as follows: the lifting drive mechanism of the present invention adopts a motor + screw rod and nut driving method. Compared with the existing cylinder driving method, the motor is easier to control accurately, so that there will be no asynchronous movement. The screw rod and nut have high transmission precision, which can ensure the synchronization of the up and down movement of the two flip drive mechanisms, and then ensure the synchronization of the up and down movement of the two half-axes, avoiding the tilting of the jig at the top and the bottom of the jig disk mechanism. After the 3D glass cover plate is placed on the jig through the loading and unloading mechanism, the position of the 3D glass cover plate will not deviate, so that the jig can stably fix the 3D glass cover plate, improve the stability of the 3D glass cover plate, and improve the polishing efficiency.

[0027] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0028] Please refer to Figure 1 and Figure 2A polishing machine provided by one embodiment of the present invention includes a polishing mechanism 10, a jig disk mechanism 20, two half-axes 30, two flipping drive mechanisms 40, two lifting drive mechanisms 50, two clamping mechanisms 60 and a loading and unloading mechanism 70. The polishing mechanism 10, the jig disk mechanism 20 and the loading and unloading mechanism 70 are arranged in sequence from bottom to top. The polishing mechanism 10 is used to polish the front of the 3D glass cover 200 on the jig 21. The top and bottom ends of the jig disk mechanism 20 are respectively provided with jigs 21 for fixing the 3D glass cover 200. The two flipping drive mechanisms 40 are arranged opposite to each other on the left and right, and the jig disk mechanism 20 is located between the two flipping drive mechanisms 40. One end of the two half-axes 30 is respectively connected to the two sides of the jig disk mechanism 20, and the other ends of the two half-axes 30 are respectively connected to the two flipping drive mechanisms 40. The two flip drive mechanisms 40 are respectively used to drive the two half-shafts 30 to rotate, thereby driving the jig tray mechanism 20 to flip, so that the jig 21 at the top of the jig tray mechanism 20 is opposite the polishing mechanism 10, or the jig 21 at the bottom of the jig tray mechanism 20 is opposite the polishing mechanism 20. The two lifting drive mechanisms 50 correspond to the two flip drive mechanisms 40 and are respectively connected to the corresponding flip drive mechanisms 40. The two lifting drive mechanisms 50 are respectively used to drive the two flip drive mechanisms 40 to move up and down, thereby driving the two half-shafts 30 to move up and down, and further driving the jig tray mechanism 20 and the jig 21 thereon to move up and down. The two clamping mechanisms 60 are arranged in a left-right relationship and correspond to the two half-axes 30 and the two flip drive mechanisms 40, respectively. The two clamping mechanisms 60 are respectively arranged on the two flip drive mechanisms 40. The up and down movement of the two flip drive mechanisms 40 can respectively drive the two clamping mechanisms 60 to move up and down. The two clamping mechanisms 60 are used to clamp the two half-axes 30 to prevent the two half-axes 30 from rotating along their own axes during the polishing process, thereby preventing the jig plate mechanism 20 from rotating. This facilitates material loading and unloading and polishing, and improves the loading and unloading accuracy and polishing precision. The loading and unloading mechanism 70 is used to place the 3D glass cover plate 200 on the jig 21 and to remove the 3D glass cover plate 200 from the jig 21.

[0029] Specific, combined Figure 3 and Figure 4As shown, the polishing mechanism 10 includes a machine 11 and a polishing assembly. The polishing assembly includes a polishing disc 12, a polishing motor (not shown in the figure), a polishing reducer (not shown in the figure) and a rotating shaft 13. The polishing disc 12 is located above the machine 11. A polishing blanket 121 for polishing the front of the 3D glass cover 200 is provided at the top of the polishing disc 12. The polishing reducer is arranged at the bottom of the machine 11. The polishing motor is arranged on the polishing reducer. The polishing motor is preferably a three-phase asynchronous motor. The output end of the polishing motor is connected to the input end of the polishing reducer. One end of the rotating shaft 13 is connected to the bottom end of the polishing disc 12, and the other end of the rotating shaft 13 passes through the through hole at the top of the machine 11 and extends into the machine 11, and is connected to the output end of the polishing reducer. The polishing motor is used to drive the rotating shaft 13 to rotate through the polishing reducer, thereby driving the polishing disc 12 to rotate, and then driving the polishing blanket 121 to rotate. A polishing rotating bearing is provided in the through hole at the top of the machine platform 11 . The polishing rotating bearing is sleeved on the outer periphery of the rotating shaft 13 to provide support for the rotation of the rotating shaft 13 .

The gear set of the first jig disk assembly 23a is accommodated in the first accommodating groove 225 (see FIG. 2 ) at the top of the fixing member 22. Figure 8), the gear set of the second jig tray assembly 23b is housed in the second receiving groove at the bottom of the fixing member 22. The output end of the jig tray motor 232 of the first jig tray assembly 23a passes through the through hole at the bottom end of the first motor plate 223 and is located in the first receiving groove 225. The output end of the jig tray motor 232 of the second jig tray assembly 23b passes through the through hole at the top end of the second motor plate 224 and is located in the second receiving groove. The output end of the jig tray motor 232 is connected to the gear set.

[0032] The jig disk reducer 233 of the first jig disk assembly 23a is arranged at the top of the fixing member 22 and the jig disk reducer 233 passes through the first fixing disk 221. The output end of the jig disk reducer 233 of the first jig disk assembly 23a is connected to the bottom end of the jig disk 231 of the first jig disk assembly 23a. The jig disk reducer 233 of the second jig disk assembly 23b is arranged at the bottom end of the fixing member 22 and the jig disk reducer 233 passes through the second fixing disk 222. The output end of the jig disk reducer 233 of the second jig disk assembly 23b is connected to the top end of the jig disk 231 of the second jig disk assembly 23b. The top and bottom ends of the fixing member 22 are respectively provided with a first through hole and a second through hole, the first through hole is connected to the first accommodating groove 225, and the second through hole is connected to the second accommodating groove. The input end of the jig disk reducer 233 of the first jig disk assembly 23a passes through the first through hole and extends into the first accommodating groove 225. The input end of the jig disk reducer 233 of the second jig disk assembly 23b passes through the second through hole and extends into the second accommodating groove. The gear set is connected to the input end of the jig disk reducer 233. The jig disk motor 232 is used to drive the jig disk 231 to rotate through the gear set and the jig disk reducer 233. The jig 21 is respectively provided at the top end of the jig disk 231 of the first jig disk assembly 23a and the bottom end of the jig disk 231 of the second jig disk assembly 23b. The rotation of the jig disk 231 can drive the jig 21 to rotate.

[0033] In this embodiment, the gear set includes a first gear 2341 and a second gear 2342. The first gear 2341 is mounted on the outer periphery of the output end of the fixture disk motor 232. The second gear 2342 meshes with the first gear 2341 and is mounted on the outer periphery of the input end of the fixture disk reducer 233. The fixture disk motor 232 is a servo motor, and the fixture disk reducer 233 is a harmonic reducer. By using a servo motor and a harmonic reducer, the rotation angle of the fixture disk 231 can be accurately monitored, thereby ensuring the accuracy of the position of the fixture disk 231 and, in turn, ensuring that the loading and unloading mechanism 70 can accurately remove and place materials from the fixture 21.

[0034] In this embodiment, the first jig tray assembly 23a and the second jig tray assembly 23b are respectively multiple, for example, four, and the four first jig tray assemblies 23a are spaced apart around the axis of the first fixed disk 221, and the four second jig tray assemblies 23b are spaced apart around the axis of the second fixed disk 222. It can be understood that the number of the first jig tray assemblies 23a and the second jig tray assemblies 23b can be set according to actual conditions. The jig 21 at the top of the jig tray 231 of the first jig tray assembly 23a and the jig 21 at the bottom of the jig tray 231 of the second jig tray assembly 23b are respectively multiple, for example, nine, and the nine jigs 21 are spaced apart. It can be understood that the number of the jigs 21 can be set according to actual conditions. There are multiple first jig tray assemblies 23a and multiple second jig tray assemblies 23b, and there are multiple jigs 21 at the top of each jig tray 231 of the first jig tray assembly 23a and multiple jigs 21 at the bottom of each jig tray 231 of the second jig tray assembly 23b, so that the present invention can polish multiple 3D glass cover plates 200 at one time.

[0035] The end of the jig 21 away from the jig plate 231 has a placement position for the 3D glass cover 200, and the bottom of the placement position has an adsorption groove 211, which extends to the end of the jig 21 close to the jig plate 231. Figure 7 As shown, the jig tray 231 has a vacuum channel running through its top and bottom ends. The vacuum channel corresponds to the jig 21. One end of the vacuum channel is connected to the corresponding adsorption groove 211 of the jig 21, and the other end of the vacuum channel is used to connect to the first vacuum pumping device. After the 3D glass cover plate 200 is placed on the placement position of the jig 21 by the loading and unloading mechanism 70, the adsorption groove 211 is vacuumed by the first vacuum pumping device through the vacuum channel, so that the adsorption groove 211 can adsorb the 3D glass cover plate 200, thereby fixing the 3D glass cover plate 200. The first vacuum pumping device stops vacuuming the adsorption groove 211 through the vacuum channel, so that the adsorption groove 211 stops adsorbing the 3D glass cover plate 200, thereby releasing the 3D glass cover plate 200. At this time, the 3D glass cover plate 200 can be removed from the placement position of the jig 21 by the loading and unloading mechanism 70.

[0036] Combine Figure 5 、 Figure 6 、 Figures 10 to 14As shown, the lifting drive mechanism 50 includes a lifting mounting plate 51, a fixed plate 52, a lifting motor 53, a lifting screw 55, and a lifting nut 56.

The other end of the lifting screw 55 is rotatably mounted in a through-hole 521 at the bottom of the fixed plate 52. The lifting motor 53 is used to drive the lifting screw 55 to rotate. The lifting nut 56 is threadedly engaged with the lifting screw 55 and connected to the corresponding flipping drive mechanism 40. The rotation of the lifting screw 55 can drive the lifting nut 56 to move up and down, thereby driving the two flip driving mechanisms 40 to move up and down through the lifting nuts 56 of the two lifting driving mechanisms 50.

[0037] In this embodiment, a first lifting and rotating bearing is disposed within the through-hole at the top of the lifting mounting plate 51. The first lifting and rotating bearing is mounted around one end of the lifting screw 55.

The two racks 111 can provide installation support for the two lifting drive mechanisms 50. In this embodiment, the two racks 111 and the lifting mounting plates 51 of the two lifting drive mechanisms 50 are respectively fixed to the two protective covers 80 (see FIG. Figure 1), two protective covers 80 are respectively fixed on both sides of the machine table 11 of the polishing mechanism 10, and the lifting motors 53, columns 54, lifting screws 55 and lifting nuts 56 of the two lifting drive mechanisms 50, the two flip drive mechanisms 40 and the two clamping mechanisms 60 are respectively located in the protective covers 80. The two protective covers 80 provided play a protective role for the two lifting drive mechanisms 50, the two flip drive mechanisms 40 and the two clamping mechanisms 60. The fixing plates 52 of the two lifting drive mechanisms 50 are respectively provided on the top ends of the two protective covers 80. The two protective covers 80 are provided on the side close to the machine table 11 for circumventing the two half-shafts 30, and the top ends of the two protective covers 80 are respectively provided with second circumventing holes for circumventing the lifting screws 55 of the two lifting drive mechanisms 50 and third circumventing holes for circumventing the columns 54 of the two lifting drive mechanisms 50.

[0039] The flip drive mechanism 40 includes a flip mounting plate 42, a flip motor 43, a flip reducer 44, a flip screw 45, a flip nut 46 and a rack 47. The lifting mounting plate 51 is located below the flip mounting plate 42 of the corresponding flip drive mechanism 40. The flip mounting plate 42 is provided with a flip mounting hole, and the lifting nut 56 is arranged in the flip mounting hole of the corresponding flip drive mechanism 40, and the top and bottom ends of the lifting nut 56 respectively protrude from the top and bottom ends of the flip mounting plate 42 of the corresponding flip drive mechanism 40. The flip reducer 44 is arranged at the bottom end of the flip mounting plate 42 through the reducer base 441, and the flip motor 43 is arranged on the flip reducer 44, and the output end of the flip motor 43 is connected to the input end of the flip reducer 44. The flip motor 43 is preferably a servo motor. The flip screw 45 is rotatably mounted at the bottom end of the flip mounting plate 42 via a screw bearing seat 451. One end of the flip screw 45 is connected to the output end of the flip reducer 44. The length of the flip screw 45 is the same as the width of the flip mounting plate 42. The lifting screw 55 of the left lifting drive mechanism 50 is located behind the flip screw 45 of the corresponding flip drive mechanism 40, and the lifting screw 55 of the right lifting drive mechanism 40 is located in front of the flip screw 45 of the corresponding flip drive mechanism 40. The number of screw bearing seats 451 can be set according to actual conditions. The flip motor 43 is used to drive the flip screw 45 to rotate via the flip reducer 44. The flip nut 46 is threadedly engaged with the flip screw 45. The length of the rack 47 is the same as the width of the flip mounting plate 42. The rack 47 is slidably mounted on the top of the flip mounting plate 42 and connected to the flip nut 46. The other ends of the two half-shafts 30 are rotatably mounted on the top ends of the flip mounting plates 42 of the two flip drive mechanisms 40 via respective half-shaft bearing seats 311. Two flip gears 48 are sleeved around the outer circumferences of the other ends of the two half-shafts 30. The two flip gears 48 are positioned above and mesh with the racks 47 of the two flip drive mechanisms 40. The rotation of the flip screw 45 drives the flip nut 46 back and forth, thereby driving the rack 47 back and forth, which in turn drives the corresponding gear 48 to rotate, and in turn drives the corresponding half-shaft 30 to rotate. The rotation of the two half-shafts 30 causes the fixture plate mechanism 20 to flip.The up and down movement of the lifting nut 56 can drive the corresponding flip mounting plate 42 of the flip driving mechanism 40 to move up and down, thereby driving the corresponding flip screw 45, flip motor 43, flip reducer 44, flip nut 46, and rack 46 of the flip driving mechanism 40 to move up and down, and then drive the corresponding flip gear 48 and half-shaft 30 to move up and down. The up and down movement of the two half-shafts 30 can drive the fixing part 22 of the jig disk mechanism 20 to move up and down, and then drive the first fixed disk 221, the second fixed disk 222, the first jig disk assembly 23a, and the second jig disk assembly 23b to move up and down, and then drive the jig 21 at the top of the jig disk 231 of the first jig disk assembly 23a and the jig 21 at the bottom of the jig disk 231 of the second jig disk assembly 23b to move up and down.

[0040] In this embodiment, the lifting drive mechanism 50 further includes a guide rod 57. One end of the guide rod 57 is disposed at the bottom end of the fixed plate 52. The other end of the guide rod 57 passes through a hole in the corresponding flip mounting plate 42 of the flip drive mechanism 40 and is positioned below the corresponding flip mounting plate 42 of the flip drive mechanism 40. A linear bearing 58 is disposed within the hole in the flip mounting plate 42 and sleeved around the outer circumference of the corresponding guide rod 57. The guide rod 57 guides the up and down movement of the flip mounting plate 42 of the corresponding flip drive mechanism 40. The linear bearing 58 provides support for the movement of the corresponding guide rod 57. The number of guide rods 57 can be adjusted based on actual conditions; the number of holes in the flip mounting plate 42 and the number of linear bearings 58 correspond to the number of corresponding guide rods 57. The top ends of the two protective covers 80 are each provided with a fourth clearance hole for allowing the guide rods 57 of the two lifting drive mechanisms 50 to clear.

[0041] In this embodiment, the top of the flip mounting plate 42 is provided with a through hole 422 corresponding to the rack 47. The bottom end of the rack 47 is provided with a connecting piece 472. The end of the connecting piece 472, away from the rack 47, passes through the through hole 422 and is connected to the flip nut 46. The forward and backward movement of the flip nut 46 drives the connecting piece 472 to move forward and backward between the two ends of the through hole 422, thereby driving the rack 47 to move forward and backward.

[0042] The rack 47 is slidably set on the top of the flip mounting plate 42. Specifically, two fixed blocks 421 are arranged opposite to each other on the left and right sides at the top of the flip mounting plate 42. The length direction of the fixed block 421 is the same as the width direction of the flip mounting plate 42. The through hole 422 is located between the two fixed blocks 421. Two sliders 4211 are respectively formed on the adjacent sides of the two fixed blocks 421. The length direction of the slider 4211 is the same as the width direction of the flip mounting plate 42. Two sliding grooves 471 are respectively provided on both sides of the rack 47. The two sliders 4211 slide with the two sliding grooves 471 respectively.

[0043] The two clamping mechanisms 60 are respectively located between the half-shaft bearing seats 311 of the two half-shafts 30 and the fixture disk mechanism 20. The clamping mechanism 60 includes a support base 61, two first connecting rods 62, a second connecting rod 63, two third connecting rods 64, and two clamping cylinders 65. The support base 61 is mounted at the top of the corresponding flip mounting plate 42 of the flip drive mechanism 40, with the two first connecting rods 62 arranged in a front-to-back relationship. The first ends of the two first connecting rods 62 are hinged to the top of the support base 61 via two first hinge shafts 621. The second connecting rod 63 is located above the support base 61 and between the second ends of the two first connecting rods 62. The second connecting rod 63 is horizontal, and the two third connecting rods 64 are arranged in a front-to-back relationship. The third connecting rods 64 are tilted upward. The first ends of the two third connecting rods 64 are hinged to the two ends of the second connecting rod 63 via two second hinge shafts 631. The second ends of the two third connecting rods 64 are connected to the output ends of the two clamping cylinders 65. The two clamping cylinders 65 are arranged in a front-to-back relationship. The two clamping cylinders 65 are respectively arranged at the top of the flip mounting plate 42 of the corresponding flip drive mechanism 40. The two clamping cylinders 65 are respectively used to drive the second ends of the two third connecting rods 64 to move up and down. The second ends of the two first connecting rods 62 are respectively hinged to the two third connecting rods 64 through two third hinge shafts 622. A space is formed between the support base 61, the two first connecting rods 62, and the second connecting rod 63, and the other end of the half-shaft 30 passes through the space of the corresponding clamping mechanism 60. The upward movement of the second ends of the two third connecting rods 64 can drive the first ends of the two third connecting rods 64 to move downward, and the downward movement of the first ends of the two third connecting rods 64 can drive the second connecting rod 63 to move downward, so that the bottom end of the second connecting rod 63 abuts against the outer wall of the corresponding half-shaft 30, thereby achieving the clamping of the corresponding half-shaft 30. The downward movement of the second ends of the two third links 64 can drive the first ends of the two third links 64 to move upward, and the upward movement of the first ends of the two third links 64 can drive the second link 63 to move upward, so that the bottom end of the second link 63 is separated from the outer wall of the corresponding half-shaft 30, thereby releasing the corresponding half-shaft 30. The second ends of the two first links 62 are respectively hinged to the two third links 64 via two third hinge shafts 622. In this way, the two first links 62 can provide support points for the two third links 64 respectively. In this way, the third link 64 is equivalent to a seesaw. According to the seesaw principle, when the second ends of the two third links 64 are driven to move upward or downward respectively by the two clamping cylinders 65, the first ends of the two third links 64 can move downward or upward.

[0044] Two flattened portions 31 are formed on the outer wall of the half-shaft 30 . The two flattened portions 31 are symmetrical about the axis of the half-shaft 30 . The bottom end of the second connecting rod 63 is used to abut against the bottom of the corresponding flattened portion 31 of the half-shaft 30 .

[0045] Combine Figures 15 to 17As shown, the loading and unloading mechanism 70 includes two first linear modules 71, a second linear module 72, a third linear module 73 and a loading and unloading assembly 74 that are arranged opposite to each other in the left and right directions. The two first linear modules 71 are respectively arranged at the top of the fixed plates 52 of the two lifting drive mechanisms 50. The second linear module 72 is arranged at the top of the two first linear modules 71. The third linear module 73 is arranged on one side of the second linear module 72, such as the front side. The loading and unloading assembly 74 is arranged on the side of the third linear module 73 away from the second linear module 72. The two first linear modules 71 are used to drive the second linear module 72 to move forward and backward, thereby driving the third linear module 73 and the loading and unloading assembly 74 to move forward and backward. The second linear module 72 is used to drive the third linear module 73 to move left and right, thereby driving the loading and unloading assembly 74 to move left and right. The third linear module 73 is used to drive the loading and unloading assembly 74 to move up and down.

[0046] The loading and unloading assembly 74 includes a vertical plate 741, a loading and unloading motor 743, a synchronous belt unit, a rotating rod 745 and a loading and unloading unit. The vertical plate 741 is arranged on the side of the third linear module 73 away from the second linear module 72. The loading and unloading motor 743 is arranged on the side of the vertical plate 741 away from the third linear module 73 through a motor seat 7431. A support plate 742 is provided on the side of the vertical plate 741 away from the third linear module 73. The rotating rod 745 is located below the loading and unloading motor 743 and is rotatably arranged on the side of the support plate 742 away from the vertical plate 741 through a rotating rod bearing seat 7451. The bottom end of the support plate 742 is flush with the bottom end of the vertical plate 741, and the two ends of the support plate 742 protrude from the two ends of the vertical plate 741. The two ends of the rotating rod 745 protrude from the two ends of the support plate 742. The number of rotating rod bearing seats 7451 can be set according to actual conditions. The loading and unloading motor 743 is connected to the rotating rod 745 through a synchronous belt unit. The loading and unloading motor 743 is used to drive the rotating rod 745 to rotate through the synchronous belt unit.

[0047] The synchronous belt unit includes a driving pulley 7441, a driven pulley 7442, and a synchronous belt 7443 that fits around the outer circumferences of the driving pulley 7441 and the driven pulley 7442. The driving pulley 7441 fits around the outer circumference of the output end of the loading / unloading motor 743, while the driven pulley 7442 fits around the outer circumference of the rotating rod 745. The loading / unloading motor 743 drives the driving pulley 7441, which in turn drives the rotating rod 745 through the action of the driven pulley 7442 and the synchronous belt 7443.

[0048] The loading and unloading unit includes a loading and unloading mounting plate 7461, a loading and unloading cylinder 7462, a loading and unloading connecting plate 7463, a loading and unloading support plate 7464, a suction cup mounting plate 7465, and two suction cups 7466 arranged in a front-to-rear relationship. The loading and unloading mounting plate 7461 is arranged vertically, with one end connected to the rotating rod 745 and the other end extending downward. The loading and unloading mounting plate 7461 partially protrudes from the bottom end of the vertical plate 741. The loading and unloading cylinder 7462 is located on the side of the loading and unloading mounting plate close to the support plate 742. The loading and unloading connecting plate 7463 is located on the side of the loading and unloading cylinder 7462 away from the loading and unloading mounting plate 7461. The loading and unloading support plate 7464 is slidably mounted on the side of the loading and unloading connecting plate 7463 away from the loading and unloading cylinder 7462 via conventional sliders and rails. The loading and unloading support plate 7464 partially protrudes from the bottom of the loading and unloading connecting plate 7463. The suction cup mounting plate 7465 is horizontally arranged below the loading and unloading cylinder 7462 and the loading and unloading support plate 7464. The top of the suction cup mounting plate 7465 is connected to the bottom of the loading and unloading support plate 7464 and the output end of the loading and unloading cylinder 7462 (not shown in the figure), respectively. Two suction cups 7466 are respectively disposed at the bottom end of the suction cup mounting plate 7465. The loading and unloading cylinder 7462 is used to drive the suction cup mounting plate 7465 up and down, thereby driving the two suction cups 7466 up and down. The up and down movement of the suction cup mounting plate 7465 drives the loading and unloading support plate 7464 up and down relative to the loading and unloading connecting plate 7463. The rotation of the rotating rod 745 drives the loading and unloading mounting plate 7461, loading and unloading cylinder 7462, loading and unloading connecting plate 7463, loading and unloading support plate 7464, suction cup mounting plate 7465, and two suction cups 7466 to rotate about the axis of the rotating rod 745. The loading and unloading connecting plate 7463 and loading and unloading support plate 7464 provide support for the up and down movement of the suction cup mounting plate 7465, improving the stability of the up and down movement of the suction cup mounting plate 7465. The suction cup mounting plate 7465 has a channel defined within it, and a connector 74651 is provided at the top of the suction cup mounting plate 7465. The channel communicates with the connector 74651 and the two suction cups 7466, respectively. The connector 74651 is used to connect to the second vacuum device. The two suction cups 7466 are vacuumed by the second vacuuming device through the joint 74651 and the channel, so that the 3D glass cover plate 200 can be sucked by the two suction cups 7466. The second vacuuming device stops vacuuming the two suction cups 7466 through the joint 74651 and the channel, so that the 3D glass cover plate 200 can be released by the two suction cups 7466.

[0049] In this embodiment, there are multiple loading and unloading units, for example three, and the three loading and unloading units are distributed at intervals along the axial direction of the rotating rod 745. It can be understood that the number of loading and unloading units can be set according to actual conditions.

[0050] With the above structure, in actual application, the 3D glass cover plate to be processed is located in front of the loading and unloading mechanism 70. If the 3D glass cover plate 200 to be processed is in a horizontal position (with the front of the 3D glass cover plate facing up) and needs to be placed horizontally after polishing, then, in step S1, the two first linear modules 71, the second linear module 72, and the third linear module 73 first drive the loading and unloading assembly 74 to move, so that the two suction cups 7466 are positioned above the 3D glass cover plate 200 to be processed. The loading and unloading cylinder 7462 then drives the two suction cups 7466 downward to absorb the 3D glass cover plate 200. The loading and unloading cylinder 7462 then drives the two suction cups 7466 upward to their initial position. The two first linear modules 71, the second linear module 72, and the third linear module 73 then drive the loading and unloading assembly 74 to move above the jig 21 at the top of the jig tray mechanism 20. Then, the two suction cups 7466 are driven downward by the loading and unloading cylinder 7462 to place the 3D glass cover 200 on the jig 21 at the top of the jig tray mechanism 20 through the two suction cups 7466, and then the 3D glass cover 200 is fixed by the jig 21. In the process of driving the two suction cups 7466 downward by the loading and unloading cylinder 7462, the jig tray motor 232 and the jig tray reducer 233 of the first jig tray assembly 23a drive the corresponding jig tray 231 to rotate, thereby driving the jig 21 at the top of the jig tray mechanism 20 to rotate, so that the jig 21 at the top of the jig tray mechanism 20 corresponds to the 3D glass cover 200. In this way, the 3D glass cover 200 can be accurately placed on the jig 21 at the top of the jig tray mechanism 20 through the two suction cups 7466.

[0051] S2. The two flip drive mechanisms 40 then drive the two half-shafts 30 to rotate, causing the jig tray mechanism 20 to flip 180 degrees, so that the jig 21 at the top of the jig tray mechanism 20 faces the polishing mechanism 10. The jig 21 at the bottom of the jig tray mechanism 20 is now located below the loading and unloading mechanism 70. The two clamping mechanisms 60 then clamp the two half-shafts 30. The two lifting drive mechanisms 50 then drive the jig tray mechanism 20 downward, so that the front surface of the 3D glass cover plate 200 on the jig 21 at the top of the jig tray mechanism 20 contacts the polishing blanket 121. Then, the polishing motor drives the polishing disc 12 and the polishing blanket 121 to rotate, and the jig disc motor 232 and the jig disc reducer 233 of the first jig disc assembly 23a drive the corresponding jig 21 to rotate. The rotation direction of the jig 21 is opposite to the rotation direction of the polishing blanket 121, so that the front side of the 3D glass cover 200 on the jig 21 at the top of the jig disc mechanism 20 can be polished by the polishing blanket 121.

[0052] S3. During the polishing process of the 3D glass cover plate 200 on the jig 21 at the top of the jig plate mechanism 20, the 3D glass cover plate 200 is placed on the jig 21 at the bottom of the jig plate mechanism 20 through the loading and unloading mechanism 70 according to the aforementioned step S1, and then the 3D glass cover plate 200 is fixed by the jig 21 at the bottom of the jig plate mechanism 20.

[0053] S4. After polishing the 3D glass cover plate 200 on the jig 21 at the top of the jig tray mechanism 20 is completed, the jig tray mechanism 20 is first driven upward to its initial position by the two lifting drive mechanisms 50. The two half-axles 30 are then released by the two clamping mechanisms 60. The jig tray mechanism 20 is then driven 180 degrees by the two flipping drive mechanisms 40, so that the jig 21 at the bottom of the jig tray mechanism 20 is opposite the polishing mechanism 10. At this time, the jig 21 at the top of the jig tray mechanism 20 and the 3D glass cover plate 200 are located below the loading and unloading mechanism 70. The jig tray mechanism 20 is then driven downward by the two lifting drive mechanisms 50, so that the front surface of the 3D glass cover plate 200 on the jig 21 at the bottom of the jig tray mechanism 20 contacts the polishing blanket 121. Then, the polishing motor drives the polishing disc 12 and the polishing blanket 121 to rotate, and the jig disc motor 232 and the jig disc reducer 233 of the second jig disc assembly 23b drive the corresponding jig 21 to rotate. The rotation direction of the jig 21 is opposite to the rotation direction of the polishing blanket 121, so that the front surface of the 3D glass cover 200 on the jig 21 at the bottom end of the jig disc mechanism 20 can be polished by the polishing blanket 12.

[0054] S5. During the polishing process of the 3D glass cover plate 200 on the jig 21 at the bottom of the jig plate mechanism 20, the loading and unloading assembly 74 is driven to move by the two first linear modules 71, the second linear module 72, and the third linear module 73, so that the two suction cups 7466 of the loading and unloading unit are located above the 3D glass cover plate 200 on the jig 21 at the top of the jig plate mechanism 20. Then, the loading and unloading cylinder 7462 drives the two suction cups 7466 to move downward, and at the same time, the jig 21 at the top of the jig plate mechanism 20 releases the 3D glass cover plate 200, so that the two suction cups 7466 can suck the 3D glass cover plate 200 on the jig 21 at the top of the jig plate mechanism 20. Then, the loading and unloading cylinder 7462 drives the two suction cups 7466 to move upward to the initial position, so that the 3D glass cover plate 200 can be removed from the jig 21 at the top of the jig plate mechanism 20. The first, second, and third linear modules 71, 72, and 73 then drive the loading and unloading assembly 74 to position the 3D glass cover 200 above the unloading position. The loading and unloading cylinders 7462 then drive the two suction cups 7466 downward, placing the 3D glass cover 200 at the unloading position. The polished 3D glass cover 200 is then unloaded.

[0055] S6, then the loading and unloading mechanism 70 re-places the 3D glass cover plate 200 to be processed on the jig 21 at the top of the jig plate mechanism 20 according to the above step S1. Then repeat the above steps to achieve polishing of all 3D glass cover plates 200.

[0056] If the 3D glass cover plate 200 to be processed is in a vertical position (with the front of the 3D glass cover plate facing backward) and needs to be placed vertically after polishing, then, in step S11, the first linear module 71, the second linear module 72, and the third linear module 73 first drive the loading and unloading assembly 74 to move, so that the two suction cups 7466 of the loading and unloading unit are located behind the 3D glass cover plate 200 to be processed. Then, the loading and unloading motor 743 drives the loading and unloading unit to rotate 90 degrees clockwise, so that the two suction cups 7466 are opposite the 3D glass cover plate 200 to be processed. Then, the loading and unloading cylinder 7462 drives the two suction cups 7466 toward the 3D glass cover plate 200, so that the two suction cups 7466 can grasp the 3D glass cover plate 200. Then, the loading and unloading cylinder 7462 drives the two suction cups 7466 toward the rotating rod 745 to their initial position. The loading and unloading motor 743 then drives the loading and unloading unit to rotate 90 degrees counterclockwise to return it to its initial position. The 3D glass cover 200 is now positioned below the two suction cups 7466. The loading and unloading assembly 74 is then driven by the two first linear modules 71, the second linear module 72, and the third linear module 73 to move it above the jig 21 at the top of the jig tray mechanism 20. The loading and unloading cylinder 7462 then drives the two suction cups 7466 downward, allowing them to place the 3D glass cover 200 on the jig 21 at the top of the jig tray mechanism 20. The jig 21 then secures the 3D glass cover 200. In the process of driving the two suction cups 7466 downward by the loading and unloading cylinder 7462, the corresponding jig disk 231 is driven to rotate by the jig disk motor 232 and the jig disk reducer 233 of the first jig disk assembly 23a, thereby driving the jig 21 at the top of the jig disk mechanism 20 to rotate, so that the jig 21 at the top of the jig disk mechanism 20 corresponds to the 3D glass cover 200, so that the 3D glass cover 200 can be accurately placed on the jig 21 at the top of the jig disk mechanism 20 through the two suction cups 7466.

[0057] S12. Step S12 is the same as step S2. S13. During the polishing process of the 3D glass cover plate 200 on the jig 21 at the top of the jig plate mechanism 20, the loading and unloading mechanism 70 places the 3D glass cover plate 200 on the jig 21 at the bottom of the jig plate mechanism 20 according to the aforementioned step S11, and then the jig 21 at the bottom of the jig plate mechanism 20 secures the 3D glass cover plate 200. S14. Step S14 is the same as step S4.

[0058] S15. During the polishing process of the 3D glass cover plate 200 on the jig 21 at the bottom of the jig plate mechanism 20, the loading and unloading assembly 74 is driven to move by the two first linear modules 71, the second linear module 72, and the third linear module 73, so that the two suction cups 7466 of the loading and unloading unit are located above the 3D glass cover plate 200 on the jig 21 at the top of the jig plate mechanism 20. Then, the loading and unloading cylinder 7462 drives the two suction cups 7466 to move downward, and at the same time, the jig 21 at the top of the jig plate mechanism 20 releases the 3D glass cover plate 200, so that the two suction cups 7466 can suck the 3D glass cover plate 200 on the jig 21 at the top of the jig plate mechanism 20. Then, the loading and unloading cylinder 7462 drives the two suction cups 7466 to move upward to the initial position, so that the 3D glass cover plate 200 can be removed from the jig 21 at the top of the jig plate mechanism 20. The first, second, and third linear modules 71, 72, and 73 then drive the loading and unloading assembly 74 to position the 3D glass cover 200 behind the unloading position. The loading and unloading motor 743 then rotates the loading and unloading unit 90 degrees clockwise, positioning the 3D glass cover 200 in front of the two suction cups 7466. The loading and unloading cylinder 7462 then drives the two suction cups 7466 toward the unloading position, allowing them to position the 3D glass cover 200. This completes the unloading of the polished 3D glass cover 200.

[0059] S16, then the loading and unloading mechanism 70 re-places the 3D glass cover plate 200 to be processed on the jig 21 at the top of the jig plate mechanism 20 according to the above step S11. Then repeat the above steps to achieve polishing of all 3D glass cover plates 200.

[0060] The lifting drive mechanism 50 of the present invention includes a lifting mounting plate 51, a fixing plate 52, a lifting motor 53, a lifting screw 55 and a lifting nut 56. The lifting motor 53 drives the lifting screw 55 to rotate, thereby driving the lifting nut 56 to move up and down. The lifting nuts 56 of the two lifting drive mechanisms 50 move up and down, thereby driving the two flip drive mechanisms 40 to move up and down, and then driving the two half shafts 30 to move up and down. The up and down movement of the two half shafts 30 can drive the fixture plate mechanism 20 to move up and down. The lifting drive mechanism 50 adopts the motor + screw and nut driving method, which is different from the existing cylinder driving method. The motor is easier to control accurately, so there will be no asynchronous movement. The screw and nut have high transmission precision, which can ensure the synchronization of the up and down movement of the two flip drive mechanisms 40, and then ensure the synchronization of the up and down movement of the two half-shafts 30, avoiding the jig 21 at the top and the bottom of the jig disk mechanism 20 from tilting. After the 3D glass cover 200 is placed on the jig 21 through the loading and unloading mechanism 70, the position of the 3D glass cover 200 will not deviate, so that the jig 21 can stably fix the 3D glass cover 200, improve the stability of the 3D glass cover 200, and improve the polishing efficiency.
