[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] like Figs. 1 to 3 As shown, multiple base strips 1 are arranged adjacently on the placement base unit, which is set on the fixed frame 2. The fixed frame 2 is a frame composed of profiles and serves to fix and support. The translation unit can drive the placement base unit to move relative to the fixed frame 2 in a first direction. In this application, the first direction is the horizontal x-axis direction in the three-dimensional coordinate system. When the placement base unit drives the base strip 1 to approach the grinding unit set on the fixed frame 2, the grinding unit contacts the end of the base strip 1 and grinds the end of the base strip 1 into a bevel. After grinding, the base strip 1 is removed from the placement base unit. After the grinding surfaces at the beginning and end are glued together, the assembly of the base strip ring can be completed.

[0027] like Figs. 1 to 3As shown, the base unit includes a horizontal base plate 3, a pad 4, and a pressure strip 5. The horizontal base plate 3 is a rectangular metal plate, and the pad 4 is a strip plate. The pad 4 is disposed at one end of the upper surface of the horizontal base plate 3. The two ends of the substrate strip 1 are the first end 101 and the second end 102, which are the beginning and end ends of the substrate strip 1. The middle section of the substrate strip 1 is placed on the pad 4, and the pressure strip 5 presses the middle section of the substrate strip 1 tightly against the pad 4. A hand-tightening bolt 6 passes through the pressure strip 5 and connects to the horizontal base plate 3. The middle section of the substrate strip 1 is connected 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 substrate 1 are respectively connected to the upper surface of the end of the horizontal substrate 3 without the pad 4. The first end 101 and the second end 102 of the substrate 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 of the horizontal substrate 3. That is, when the first end 101 and the second end 102 come into contact with the grinding unit for grinding, the grinding surfaces formed by the first end 101 and the second end 102 are complementary quadrilateral surfaces, thus completing the end-to-end connection. The subsequent bonding and joining process can be seamless. In this embodiment, eight substrate strips 1 are arranged in an abutting arrangement, which can simultaneously complete the grinding of the first and last ends of the eight substrate strips 1, improving efficiency. The first end 101 and the second end 102 of the substrate 1 are detachably connected to the horizontal substrate 3. Specifically, they can be connected to the horizontal substrate 3 by adhesive tape. Since the polished surface of the substrate 1 should be beveled to ensure the maximum contact area between the polished surfaces at both ends, a pad 4 is used to raise the height of the middle section of the substrate 1. This ensures that when the substrate 1 is fixed to the horizontal substrate, the vertical height of its first end 101 and the second end 102 is lower than the height of the pad 4. It should be noted that eight substrates are used in this application. The actual number of substrates 1 can be implemented according to the size of the horizontal substrate 3 and is not limited here.

[0028] In some implementations, such as Figs. 1 to 2 As shown, a reference plate 7 is provided on the horizontal substrate. The reference plate 7 is a rectangular wooden board. The area of ​​the reference plate 7 is smaller than the area of ​​the horizontal substrate 3 and is located on the upper surface of the horizontal substrate 3 in the direction close to the first end 101 and the second end 102 of the substrate strip 1. The reference plate 7 is used to determine the grinding reference surface of the grinding unit. When the substrate strip 1 is not placed, the reference plate 7 is pre-grinded by the grinding unit. 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 substrate strip 1 are connected to the reference plate 7 by means of adhesive or other methods. This improves the grinding accuracy and reduces the error caused by factors such as unevenness of the horizontal substrate 3 or insufficient flatness of the grinding unit.

[0029] In some implementations, such as Figs. 1 to 3As shown, the translation unit includes a push rod 8, a lever arm shaft 9, a synchronizing rod 10, and a joint bearing connecting rod 11. The lever arm shaft 9 is oriented in the horizontal y-axis direction and 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 via a locking sleeve, and the other end of the lever arm shaft 9 is fixedly connected to one end of the synchronizing rod 10 via a locking sleeve. The length of the synchronizing rod 10 is less than the length of the push rod 8, and the synchronizing rod 10 rotates synchronously with the push rod 8. The other end of the synchronizing rod 10 is connected to one end of the joint bearing connecting rod 11. The horizontal base plate 3 is hinged at one end, and the other end of the spherical bearing connecting rod 11 is hinged to the spherical bearing connecting seat 13. The spherical 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 spherical bearing connecting rod 11 will cause the horizontal base plate 3 to move away from the grinding unit. When the push rod 8 is pushed upward, the spherical bearing connecting rod 11 will cause the horizontal base plate 3 to move towards the grinding unit, thereby causing the first end 101 and the second end 102 of the substrate 1 to move away from or towards the grinding unit, completing the contact and separation between the substrate 1 and the grinding unit. The push rod 8, the lever arm shaft 9 and the synchronizing rod 10 are used to form a force-saving mechanism. The use of the spherical bearing connecting rod 11 can ensure that the horizontal base plate 3 has a buffer during translation and will not cause damage to the device due to excessive movement.

[0030] In some implementations, such as Figs. 1 to 3 As shown, the system includes a horizontal guide assembly, which includes a first linear guide post 14 and a first linear bearing 15. There are two first linear guide posts 14, which are respectively mounted on the left and right ends of the fixed frame 2 via brackets 16. The length direction of the first linear guide post 14 is the first direction, i.e. the x-axis direction. Several first linear bearings 15 are sleeved on the first linear guide post 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 post 14 play a role in horizontal guidance.

[0031] In some implementations, such as Figs. 1 to 6 As shown, the polishing unit includes a polishing component and a vertical rotation component. The vertical rotation component includes a rotating base plate 17, which consists of two plates. A connecting shaft 18 is fixedly inserted between the two rotating base plates 17. The two ends of the connecting shaft 18 extend out of the outer surface of the corresponding rotating base plate 17. A rotating bearing seat 19 is provided at the end of the fixed frame 2 away from the horizontal base plate 3. The two ends of the connecting shaft 18 are fitted into the rotating bearing seats 19 on both sides. The rotating base plate 17 can rotate vertically around the connecting shaft 18. The polishing component is disposed on the rotating base plate 17. By rotating the rotating base plate 17, the polishing component can be driven to rotate around the connecting shaft 18, so that the polishing component moves closer to or away from the first end 101 and the second end 102 of the substrate 1.

[0032] In some implementations, such as Figs. 1 to 6As shown, the polishing unit also includes a polishing translation component, which includes a second linear guide post 20 and a second linear bearing 21. Two second linear guide posts 20 are positioned along a second direction between the rotating substrates 17 on both sides. A plurality of second linear bearings 21 are sleeved on the second linear guide posts 20. The length direction of the second linear guide posts 20 is the second direction, i.e., the horizontal y-direction, which is horizontally orthogonal to the first direction. The second linear bearings 21 are fixedly connected to the polishing component. The polishing component can move horizontally along the second linear guide post 20 relative to the fixed frame 2 along the second direction. That is, the polishing component can polish the substrate 1 sequentially from left to right or from right to left along the second direction without needing to reposition the substrate 1, greatly improving polishing efficiency. A first buffer block 22 is provided on the inner side of the rotating substrate 17. The first buffer block 22 can contact the polishing component to prevent collision between the polishing component and the rotating substrate 17.

[0033] In some implementations, such as Figs. 5 to 6 As shown, the grinding assembly structure is as follows: the mounting plate includes an L-shaped plate 23 and a vertical plate 24. A second linear bearing 21 is fixedly installed on one side of the L-shaped plate 23, and a motor 25 is fixedly installed on the top of the L-shaped plate 23. The vertical plate 24 is vertically connected to the L-shaped plate 23. The drive wheel 26 is vertically installed on the upper end of the vertical plate 24 through a bearing seat. The drive wheel 26 and the motor 25 are driven by a transmission belt 27. The driven wheel 28 is located below the drive wheel 26. The grinding belt 29 is sleeved between the drive wheel 26 and the driven wheel 28. When the motor 25 drives the drive wheel 26 to rotate, it drives the grinding belt 29 to rotate. The rotating grinding belt 29 contacts the end of the substrate belt 1, thus performing the grinding function.

[0034] In some implementations, such as Figs. 5 to 6 As shown, a tensioning element is included. The tensioning element is used to adjust the linear distance between the driven wheel 28 and the driving wheel 26 to tension the grinding belt 29. The tensioning element includes an adjusting shaft 30, a boss 31, and an adjusting bolt 32. The driven wheel 28 is sleeved on the adjusting shaft 30 through a bearing. The boss 31 is fixedly set on the vertical plate 24. The adjusting bolt 32 passes through the boss 31 and is connected to the adjusting shaft 30. By rotating the adjusting bolt 32, the distance between the adjusting shaft 30 and the boss 31 can be changed, thereby adjusting the distance between the driven wheel 28 and the driving wheel 26, and thus adjusting the tension of the grinding belt 29.

[0035] In some implementations, such as Figs. 5 to 6 As shown, a handle 33 is provided on one side of the upright plate 24. The operator can rotate the grinding component and / or move the grinding component horizontally by using the handle 33, which facilitates operation.

[0036] In some implementations, such as Fig. 5 and Fig. 6As shown, on the side of the L-shaped plate 23 where the second linear bearing 21 is located, there is a dust collection box 34. The dust collection box 34 is located below the driven wheel 28 and is used to collect the dust generated during the grinding process.

[0037] In some implementations, such as Figs. 1 to 6 As shown, protective covers can be installed on the outside of the grinding belt 29 and the outside of the mounting plate for dust prevention and internal protection. The specific shape and installation position are not limited in this application.

[0038] In some implementations, such as Figs. 1 to 2 As shown, a wedge-shaped strip 35 is provided on one side of the horizontal substrate 3. The length direction of the wedge-shaped strip 35 extends along the first direction. The height of the wedge-shaped strip 35 in the direction close to the rotating substrate 17 is lower than the height of the wedge-shaped strip 35 in the direction away from the rotating substrate 17. The wedge-shaped strip 35 is fixed to the upper surface of the horizontal substrate 3 by a fixing block 36. At the corresponding position of the rotating substrate 17, a downward roller 37 is provided. When in a natural state, under the action of gravity, the roller 37 abuts against the upper surface of the wedge-shaped strip 35. When the horizontal substrate 3 moves horizontally relative to the fixing frame 2, the roller 37 moves relative to the wedge-shaped strip 35 and rolls, reducing friction. The roller 37 is adjustablely connected to the rotating base plate 17 via an adjustment assembly. The adjustment assembly includes a fixing member 38 fixedly connected to the rotating base plate. An adjustment bolt 39 passes through the fixing member 38 and is connected to the roller mounting member 40. The roller 37 is freely disposed at the lower end of the roller mounting member 40. By rotating the adjustment bolt 39, the roller mounting member 40 and the roller 37 are moved up and down relative to the fixing member 38. By adjusting the distance between the roller 37 and the fixing member 38, the distance between the end of the grinding belt 29 and the substrate belt 1 can be adjusted, that is, the position and height of the grinding belt 29 can be finely adjusted to adapt to substrate belts 1 of different thicknesses, thereby improving the grinding accuracy and versatility.

[0039] In some implementations, such as Figs. 1 to 2 The wedge-shaped strip shown is provided with a limiting block 41. The limiting block 41 is detachably set on the wedge-shaped strip 35 by bolts. The limiting block 41 is higher than the upper surface of the wedge-shaped strip 35. The limiting block 41 blocks the movement distance of the roller 37 relative to the wedge-shaped strip 35, thereby limiting the distance of the grinding assembly relative to the horizontal substrate 3. This further limits the grinding depth of the grinding belt relative to the first end 101 and the second end 102 of the substrate belt 1. Thus, by adjusting the position of the limiting block 41, precise grinding can be achieved.
