[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figures 1 to 3 As shown, multiple film base belts 1 are arranged on a placing base unit in an adjacent abutting manner. The placing base unit is arranged on a fixed frame 2. The fixed frame 2 is a frame composed of profiles, which plays a fixing and supporting role. The translation unit can drive the placing base unit to move in a first direction relative to the fixed frame 2. The first direction in this application is the horizontal x-axis direction in the three-dimensional coordinate. When the placing base unit drives the film base belt 1 to approach the grinding unit set on the fixed frame 2, the grinding unit contacts the end of the film base belt 1 and grinds the end of the film base belt 1 into an inclined surface. The polished film base belt 1 is removed from the placing base unit, and the grinding surfaces at the head and tail are glued and connected, so that the assembly of the film base ring belt can be completed.

[0027] like Figures 1 to 3As shown, the placement base unit includes a horizontal substrate 3, a pad 4 and a pressure strip 5. The horizontal substrate 3 is a rectangular metal plate, the pad 4 is a strip plate, the pad 4 is arranged at one end of the upper surface of the horizontal substrate 3, the two ends of the sheet base belt 1 are respectively a first end 101 and a second end 102, the first end 101 and the second end 102 are the head and tail ends of the sheet base belt 1, wherein the middle section of the sheet base belt 1 is placed on the pad 4, the pressure strip 5 presses the middle section of the sheet base belt 1 against the pad 4, the hand tightening bolt 6 is passed through the pressure strip 5 and connected to the horizontal substrate 3, and the middle section of the sheet base belt 1 is tightened to the pad 4 by rotating the hand tightening bolt 6. After being pressed and fixed, the first end 101 and the second end 102 of the sheet base belt 1 are respectively connected to the upper surface of the end of the horizontal substrate 3 where the pad 4 is not provided. The first end 101 and the second end 102 of the sheet base belt 1 are connected to the horizontal substrate 3 at a certain angle, and the first end 101 and the second end 102 are mirror images relative to the horizontal substrate 3, that is, when the first end 101 and the second end 102 are in contact with the polishing unit for polishing, the polishing surface formed by the first end 101 and the second end 102 is a complementary quadrilateral surface, and the head-to-tail connection can be completed, and the subsequent pasting and docking process can be seamlessly docked. In this embodiment, eight sheet base belts 1 are arranged in abutment, and the head and tail ends of the eight sheet base belts 1 can be polished at the same time to improve efficiency. The first end 101 and the second end 102 of the sheet base belt 1 are detachably connected to the horizontal substrate 3, and can be connected to the horizontal substrate 3 by adhesive tape. Since the polished surface of the sheet base belt 1 should be an inclined surface, the polished surface butted end to end can be ensured to have the largest butt area, so a pad 4 is used to raise the height of the middle section of the sheet base belt 1, so that when the sheet base belt 1 is fixed to the horizontal substrate, the vertical height of the first end 101 and the second end 102 is lower than the height of the pad 4. It should be noted that eight sheet base belts are used in this application, and the actual number of sheet base belts 1 can be implemented according to the size of the horizontal substrate 3, and is not limited here.

[0028] In some embodiments, Figures 1 to 2 As shown, a reference plate 7 is arranged on the horizontal substrate. The reference plate 7 is a rectangular wooden board. The area of ​​the reference plate 7 is smaller than that of the horizontal substrate 3 and is located on the upper surface of the horizontal substrate 3 close to the first end 101 and the second end 102 of the film base belt 1. The reference plate 7 is used to determine the grinding reference surface of the grinding unit. When the film base belt 1 is not placed, the reference plate 7 is pre-grinded by the grinding unit, and the upper surface of the pre-grinded reference plate 7 is used as the grinding reference surface. Then, the first end 101 and the second end 102 of the film base belt 1 are connected to the reference plate 7 by gluing or the like, thereby improving the grinding accuracy and reducing the errors caused by other factors such as the unevenness of the horizontal substrate 3 or the insufficient flatness of the grinding unit.

[0029] In some embodiments, Figures 1 to 3As shown, the translation unit includes a push rod 8, a lever arm shaft 9, a synchronization rod 10 and a joint bearing connecting rod 11. The direction of the lever arm shaft 9 is the horizontal y-axis direction. The lever arm shaft 9 is sleeved on a bearing seat 12. The bearing seat 12 is fixedly connected to the fixed frame 2. One end of the push rod 8 is fixedly connected to one end of the lever arm shaft 9 through a locking sleeve. The other end of the lever arm shaft 9 is fixedly connected to one end of the synchronization rod 10 through a locking sleeve. The length of the synchronization rod 10 is less than that of the push rod 8. The synchronization rod 10 rotates synchronously with the push rod 8. The other end of the synchronization rod 10 is fixed to one end of the joint bearing connecting rod 11. The first end 101 and the second end 102 of the sheet base belt 1 are hingedly connected, and the other end of the joint bearing connecting rod 11 is hingedly connected through the joint bearing connecting seat 13. The joint bearing connecting seat 13 is fixedly connected to the lower surface of the horizontal base plate 3. When the push rod 8 is rotated downward, the joint bearing connecting rod 11 will drive the horizontal base plate 3 to move away from the grinding unit. When the push rod 8 is pushed upward, the joint bearing connecting rod 11 will drive the horizontal base plate 3 to move toward the grinding unit, thereby driving the first end 101 and the second end 102 of the sheet base belt 1 away from or close to the grinding unit, completing the contact and separation between the sheet base belt 1 and the grinding unit. The push rod 8, the force arm shaft 9 and the synchronous rod 10 are used to form a labor-saving mechanism. The joint bearing connecting rod 11 can ensure that the translation process of the horizontal base plate 3 has a buffer, and the device will not be damaged due to excessive movement.

[0030] In some embodiments, Figures 1 to 3 As shown, it includes a horizontal guide component, which includes a first linear guide column 14 and a first linear bearing 15. There are two first linear guide columns 14, which are respectively mounted on the left and right ends of the fixed frame 2 through a bracket 16. The length direction of the first linear guide column 14 is the first direction, that is, the x-axis direction. A plurality of first linear bearings 15 are sleeved on the first linear guide column 14. The first linear bearings 15 are fixedly connected to the lower surface of the horizontal base plate 3. The first linear bearings 15 and the first linear guide column 14 play a role of horizontal guidance.

[0031] In some embodiments, Figures 1 to 6 As shown, the grinding unit includes a grinding component and a vertical rotating component. The vertical rotating component includes a rotating base plate 17. The rotating base plate 17 is divided into two pieces. A connecting shaft 18 is fixedly passed through the two rotating base plates 17. Both ends of the connecting shaft 18 pass through the outer surface of the rotating base plate 17 on the corresponding side. A rotating bearing seat 19 is provided at one end of the fixed frame 2 away from the horizontal base plate 3. Both ends of the connecting shaft 18 are sleeved in the rotating bearing seats 19 on both sides. The rotating base plate 17 can rotate vertically around the connecting shaft 18. The grinding component is arranged on the rotating base plate 17. By rotating the rotating base plate 17, the grinding component can be driven to rotate around the connecting shaft 18, so as to complete the grinding component approaching or moving away from the first end 101 and the second end 102 of the film base belt 1.

[0032] In some embodiments, Figures 1 to 6As shown, the polishing unit also includes a polishing translation assembly, which includes a second linear guide column 20 and a second linear bearing 21. The two second linear guide columns 20 are arranged between the rotating base plates 17 on both sides along the second direction. A plurality of second linear bearings 21 are sleeved on the second linear guide columns 20. The length direction of the second linear guide column 20 is the second direction, that is, the horizontal y direction, which is horizontally orthogonal to the first direction. The second linear bearing 21 is fixedly connected to the polishing assembly. The polishing assembly can be horizontally displaced along the second direction relative to the fixed frame 2 along the second linear guide column 20, that is, the polishing assembly can polish the film base belt 1 from left to right, or from right to left in sequence along the second direction, without the need to reorganize the position of the film base belt 1, which greatly improves the polishing efficiency. A first buffer block 22 is provided on the inner side of the rotating base plate 17, and the first buffer block 22 can contact the polishing assembly to prevent the polishing assembly from colliding with the rotating base plate 17.

[0033] In some embodiments, Figures 5 and 6 As shown, the structure of the grinding assembly is as follows: the mounting plate includes an L-shaped plate 23 and a vertical plate 24; a second linear bearing 21 is fixedly provided on one side of the L-shaped plate 23; a motor 25 is fixedly provided on the top of the L-shaped plate 23; the vertical plate 24 is vertically connected to the L-shaped plate 23; a driving wheel 26 is vertically provided at the upper end of the vertical plate 24 through a bearing seat; a transmission belt 27 is used to transmit the power to the driving wheel 26 and the motor 25; a driven wheel 28 is provided below the driving wheel 26; a grinding belt 29 is sleeved between the driving wheel 26 and the driven wheel 28; when the motor 25 drives the driving wheel 26 to rotate, the grinding belt 29 is driven to rotate; the rotating grinding belt 29 contacts the end of the sheet base belt 1, thereby performing a grinding function.

[0034] In some embodiments, Figures 5 and 6 As shown, it includes a tensioning member, which is used to adjust the linear distance between the driven wheel 28 and the driving wheel 26 to play the role of tensioning the grinding belt 29. The tensioning member includes an adjusting shaft 30, a convex seat 31 and an adjusting bolt 32. The driven wheel 28 is mounted on the adjusting shaft 30 through a bearing sleeve, the convex seat 31 is fixedly arranged on the vertical plate 24, and the adjusting bolt 32 passes through the convex seat 31 and is connected to the adjusting shaft 30. By rotating the adjusting bolt 32, the distance between the adjusting shaft 30 and the convex seat 31 can be changed, thereby adjusting the distance between the driven wheel 28 and the driving wheel 26, thereby adjusting the tension of the grinding belt 29.

[0035] In some embodiments, Figures 5 and 6 As shown, a handle 33 is provided on one side of the vertical plate 24, and the operator can rotate the grinding assembly through the handle 33, and / or translate the grinding assembly through the handle 33, so as to facilitate the operation.

[0036] In some embodiments, Figure 5 and Figure 6As shown, a dust collecting box 34 is provided on one side of the L-shaped plate 23 where the second linear bearing 21 is provided. The dust collecting box 34 is arranged below the driven wheel 28 and is used to absorb the dust generated during the grinding process.

[0037] In some embodiments, Figures 1 to 6 As shown, protective covers can be provided on the outside of the grinding belt 29 and the outside of the mounting plate to prevent dust and protect the interior. The specific shape and installation position are not limited in this application.

[0038] In some embodiments, Figure 1 to Figure 2 As shown, a wedge bar 35 is provided on one side of the horizontal substrate 3, and the length direction of the wedge bar 35 extends along the first direction. The height of the wedge bar 35 in the direction close to the rotating substrate 17 is lower than the height of the wedge bar 35 in the direction away from the rotating substrate 17. The wedge bar 35 is fixed to the upper surface of the horizontal substrate 3 by a fixing block 36. A downward roller 37 is provided at a corresponding position of the rotating substrate 17. When in a natural state, under the action of gravity, the roller 37 abuts against the upper surface of the wedge bar 35. When the horizontal substrate 3 is horizontally displaced relative to the fixed frame 2, the roller 37 is relatively displaced on the wedge bar 35 and rolls, thereby reducing friction. The roller 37 is adjustably connected to the rotating base plate 17 through an adjusting assembly. The adjusting assembly includes a fixing part 38 fixedly connected to the rotating base plate. An adjusting bolt 39 passes through the fixing part 38 and is connected to the roller mounting part 40. The roller 37 is freely set at the lower end of the roller mounting part 40. By rotating the adjusting bolt 39, the roller mounting part 40 and the roller 37 are driven to move up and down relative to the fixing part 38. By adjusting the distance of the roller 37 relative to the fixing part 38, the distance of the grinding belt 29 relative to the end of the film base belt 1 can be adjusted, that is, the position height of the grinding belt 29 can be fine-tuned to make it adapt to the film base belt 1 of different thicknesses, thereby improving the grinding accuracy and versatility.

[0039] In some embodiments, Figure 1 to Figure 2 The wedge-shaped bar is provided with a limit block 41, which is detachably arranged on the wedge-shaped bar 35 by bolts. The limit block 41 is higher than the upper surface of the wedge-shaped bar 35. The limit block 41 blocks the moving distance of the roller 37 relative to the wedge-shaped bar 35, thereby limiting the distance of the grinding assembly relative to the horizontal substrate 3, and further limiting the grinding depth of the grinding belt relative to the first end 101 and the second end 102 of the sheet base belt 1, so that precise grinding can be achieved by adjusting the position of the limit block 41.
