[0023] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0024] like Figures 1 to 6 As shown, a preferred embodiment of the present invention provides a grinding device 100 having a first horizontal direction X. The grinding device 100 includes a fixing component 1, a clamping component 2, a grinding mechanism 3, and a driving mechanism 4.

[0025] The clamping assembly 2 is connected to the upper end of the fixing assembly 1 and is used to clamp and fix the workpiece 200. The clamping assembly 2 has a first rotation axis 20. The grinding mechanism 3 includes a first drive motor 31 and a grinding wheel 32. The grinding wheel 32 is located above the clamping assembly 2. The first drive motor 31 is connected to the grinding wheel 32 and can drive the grinding wheel 32 to rotate around a second rotation axis 30. The second rotation axis 30 is parallel to the first rotation axis 20. The driving mechanism 4 is connected to the fixing assembly 1 and the clamping assembly 2 respectively. The driving mechanism 4 is configured to drive the fixing assembly 1 to reciprocate along the first horizontal direction X and to drive the clamping assembly 2 to rotate around the first rotation axis 20.

[0026] Based on this technical solution, by setting the driving mechanism 4 to simultaneously drive the fixing component 1 to reciprocate along the first horizontal direction X, and drive the clamping component 2 to rotate around the first rotation axis 20, the workpiece 200 clamped and fixed on the clamping component 2 can simultaneously achieve rotational motion during the linear feed along the first horizontal direction X. Combined with the rotational motion of the grinding wheel 32 around the second rotation axis 30 parallel to the first rotation axis 20, in one clamping process, by utilizing the motion trajectory of the workpiece 200 in sequential contact with the grinding wheel 32 on both sides during the rotation process, mutually symmetrical V grooves can be independently ground on both sides of the workpiece 200, without the need for repeated clamping or adjustment of the workpiece 200 angle, thus improving processing efficiency and ease of operation.

[0027] Since the V-grooves on both sides are formed by continuous grinding with the same grinding wheel 32 during continuous rotation, the machining datum is consistent, which ensures the symmetry, angle consistency and positional accuracy of the two sides of the V-grooves, and improves the machining quality and product yield.

[0028] In this embodiment, the workpiece 200 is a substrate.

[0029] The grinding apparatus 100 has a first horizontal direction X, a second horizontal direction Y, and a vertical direction Z that are perpendicular to each other.

[0030] Specifically, in this embodiment, the first horizontal direction X is the length direction of the grinding device 100, the second horizontal direction Y is the width direction of the grinding device 100, and the vertical direction Z is the height direction of the grinding device 100; the first rotation axis 20 is perpendicular to the vertical direction Z, and the second rotation axis 30 is perpendicular to the vertical direction Z.

[0031] In this embodiment, the grinding mechanism 3 also includes a mounting frame 33, and the first drive motor 31 is mounted on the upper end of the mounting frame 33. The mounting frame 33 is used to fix it to the ground or other components.

[0032] Preferably, there are multiple clamping components 2, which are distributed at intervals along the first horizontal direction X, and one clamping component 2 clamps and fixes one workpiece 200.

[0033] By setting up multiple clamping components 2 distributed at intervals along the first horizontal direction X, the grinding device 100 can continuously process multiple workpieces 200 in the same working cycle, thereby increasing the number of workpieces processed per unit time and improving production efficiency.

[0034] In this embodiment, the number of clamping components 2 is three.

[0035] In some other embodiments, the number of clamping components 2 can also be any number, such as two, four, five, six, or seven.

[0036] Preferably, there are multiple grinding mechanisms 3, which are distributed at intervals along the first horizontal direction X, and the number of grinding mechanisms 3 is equal to or greater than the number of clamping components 2; in this way, each clamping component 2 can be synchronously ground with a grinding wheel 32, thereby realizing the parallel processing of multiple workpieces 200. Compared with the method of processing multiple workpieces 200 one by one by a single grinding wheel 32, the processing cycle is shortened and the production efficiency and output capacity of the equipment are improved.

[0037] In this embodiment, the number of grinding mechanisms 3 is seven.

[0038] In some other embodiments, the number of grinding mechanisms 3 can also be any number, such as two, three, four, five, six, etc.

[0039] See Figures 1 to 5 The fixing component 1 includes a support plate 11, a first fixing rod 12 and a second fixing rod 13. The lower end of the first fixing rod 12 is connected to the support plate 11, and the second fixing rod 13 is located on one side of the first fixing rod 12. The lower end of the second fixing rod 13 is connected to the support plate 11. The clamping component 2 is connected to the first fixing rod 12 and the second fixing rod 13 respectively and is located above the support plate 11. The driving mechanism 4 is connected to the support plate 11 to drive the support plate 11 to reciprocate along the first horizontal direction X.

[0040] The clamping assembly 2 is connected by a dual-point support method using the first fixing rod 12 and the second fixing rod 13, forming a stable frame support structure, which can improve the installation stability of the clamping assembly 2.

[0041] The fixing assembly 1 also includes a connecting rod 14, which is located below the clamping assembly 2. One end of the connecting rod 14 is connected to the first fixing rod 12 and the other end is connected to the second fixing rod 13.

[0042] Thus, the connecting rod 14 can serve as a transverse reinforcing beam connecting the first fixed rod 12 and the second fixed rod 13, forming a "U" or "H" shaped frame structure together with the support plate 11, the first fixed rod 12, and the second fixed rod 13, thereby improving the overall rigidity and installation stability of the fixing component 1, reducing the vibration or displacement of the workpiece 200 during rotation and grinding, and thus ensuring the accuracy and surface quality of the V-groove machining.

[0043] In this embodiment, the connecting rod 14 is also connected to the top of the support plate 11.

[0044] See Figures 1 to 5The clamping assembly 2 includes a first clamping member 21, a first rotating shaft 22, a first gear 23, a second clamping member 24, a second rotating shaft 25, and a spring 26. The first clamping member 21 is located between the first fixed rod 12 and the second fixed rod 13, and the second clamping member 24 is located between the first clamping member 21 and the second fixed rod 13. The first rotating shaft 22 is connected to the side of the first clamping member 21 away from the second clamping member 24 and passes through the first fixed rod 12. The central axis of the first gear 23 is the first rotation axis 20. The first gear 23 is coaxially connected to the first rotating shaft 22 and is located on the side of the first fixed rod 12 away from the first clamping member 21. The second rotating shaft 25 is connected to the side of the second clamping member 24 away from the first clamping member 21 and passes through the second fixed rod 13. The spring 26 is sleeved on the second rotating shaft 25 and is located between the second clamping member 24 and the second fixed rod 13. The driving mechanism 4 is meshed with the first gear 23 to drive the first gear 23 to rotate around the first rotation axis 20.

[0045] A clamping mechanism combining linkage rotation and elastic clamping is formed by the first clamping member 21, the second clamping member 24, the first rotating shaft 22, the second rotating shaft 25, the first gear 23, and the spring 26. The first clamping member 21 is coaxially connected to the first gear 23 through the first rotating shaft 22, and the first gear 23 is driven by the drive mechanism 4 to rotate around the first rotation axis 20, realizing the rotational movement of the workpiece 200 during the grinding process. By sleeved on the second rotating shaft 25 and acting between the second clamping member 24 and the second fixed rod 13, the second clamping member 24 can apply an elastic clamping force towards the first clamping member 21 under the pre-tightening force of the spring 26. When the substrate is manually inserted or removed, only force needs to be applied to compress the spring 26 to release the clamp, which is simple to operate and does not damage the surface of the substrate, thus taking into account both clamping reliability and ease of operation.

[0046] The first gear 23 is located outside the first fixed rod 12 and meshes with the drive mechanism 4, directly transmitting the driving force to the first rotating shaft 22 and the first clamping member 21. The transmission path is short, the response is fast, and the backlash is small, ensuring the accuracy and synchronization of the rotational motion and providing reliable motion guarantee for the precise machining of the symmetrical V-grooves on both sides of the workpiece 200.

[0047] It should be noted that "the first gear 23 is coaxially connected to the first rotating shaft 22" means that the central axis of the first gear 23 and the central axis of the first rotating shaft 22 coincide. That is, when one component is coaxially connected to another component, it means that the central axes of the two components coincide.

[0048] The first clamping member 21 is provided with a first clamping groove 211 suitable for embedding the workpiece 200, and the second clamping member 24 is arranged opposite to the first clamping groove 211 and is provided with a second clamping groove 241 suitable for embedding the workpiece 200.

[0049] The first clamping member 21 is provided with a first clamping groove 211, and the second clamping member 24 is provided with a second clamping groove 241 arranged opposite to it. The two clamping grooves are arranged opposite to each other to form an embedded clamping structure for the two ends or sides of the workpiece 200. This arrangement can restrict the degree of freedom of the workpiece 200 in the horizontal and vertical Z directions, improve the positioning accuracy and stability of the clamping, prevent the workpiece 200 from slipping or deflecting during high-speed revolution and grinding, and ensure the positional accuracy and repeatability of V-groove machining.

[0050] In this embodiment, the substrate is a circular substrate. The bottom wall of the first clamping groove 211 is an arc-shaped bottom wall adapted to the circular edge of the circular substrate, and the bottom wall of the second clamping groove 241 is also an arc-shaped bottom wall adapted to the circular edge of the circular substrate. The arc-shaped bottom wall forms a local circumferential surface contact with the outer edge of the circular substrate, increasing the contact area between the clamping groove and the substrate, and making the clamping force distribution more uniform.

[0051] Preferably, the bottom wall and / or side wall of the first clamping groove 211 are provided with flexible buffer pads, and the bottom wall and / or side wall of the second clamping groove 241 are provided with flexible buffer pads. The flexible buffer pads have good conformability and fit, and can adapt to minor morphological differences or dimensional tolerances at the edges of the substrate, achieving a "soft clamping" effect. Even under the preload of the spring 26, the clamping force remains gentle and controllable, preventing damage from excessive clamping or detachment from excessive clamping, thus improving the safety and reliability of the cleaning device.

[0052] Flexible cushioning pads can be made of flexible cushioning materials such as rubber, sponge, and silicone.

[0053] The clamping assembly 2 also includes a handle 27, which is connected to the second pivot 25 and located on the side of the second fixing rod 13 opposite to the second clamping member 24.

[0054] When it is necessary to load or replace the substrate, the operator can manually turn the handle 27 to drive the second rotating shaft 25 to move axially, thereby overcoming the preload of the spring 26 and moving the second clamping member 24 away from the first clamping member 21 to open the clamping space. At this time, the workpiece 200 can be easily inserted between the first clamping groove 211 and the second clamping groove 241. After releasing the handle 27, the spring 26 returns to its original shape and pushes the second clamping member 24 to reset, realizing automatic clamping of the workpiece 200. The operation process is simple, labor-saving, and intuitive, without the need for additional tools or complex adjustments.

[0055] The second fixing rod 13 has a clearance groove 131 on the side surface facing the second clamping member 24. The clearance groove 131 includes a first groove wall 1311 and a second groove wall 1312. The second rotating shaft 25 passes through the first groove wall 1311, and the second groove wall 1312 is connected to the lower end of the first groove wall 1311 and located below the second clamping member 24.

[0056] The recessed groove 131 provides a space for the second rotating shaft 25 and the spring 26, so that the second clamping member 24 will not mechanically collide or rub against the body of the second fixing rod 13 during clamping, releasing or rotating.

[0057] See Figures 1 to 3 ,and Figure 6 The drive mechanism 4 includes a drive device 41 and a rack 42; the drive device 41 is connected to the support plate 11 and can drive the support plate 11 to move along the first horizontal direction X; the rack 42 is located on one side of the drive device 41 and meshes with the first gear 23; the rack 42 extends along the first horizontal direction X.

[0058] When the drive device 41 drives the support plate 11 to move along the first horizontal direction X, the first gear 23 mounted on the support plate 11 translates accordingly and performs a "rolling meshing" motion on the fixed rack 42. This meshing process forces the first gear 23 to rotate around its own axis (i.e., the first rotation axis 20), which in turn drives the first clamping member 21 and the workpiece 200 to rotate synchronously through the first rotating shaft 22. Thus, the horizontal reciprocating motion and rotational motion of the workpiece 200 can be achieved simultaneously with only one linear drive action, without the need for an additional rotary motor or transmission mechanism, resulting in a simple structure.

[0059] The meshing transmission between the rack 42 and the first gear 23 has the advantages of high transmission accuracy, fast response and strong load-bearing capacity. It can ensure that the rotational motion of the clamping assembly 2 and the linear motion of the support plate 11 maintain a strict motion synchronization relationship, thereby ensuring the stability and repeatability of the trajectory of the workpiece 200 during rotation, and providing reliable motion guarantee for high-precision and continuous grinding of the symmetrical V-grooves on both sides.

[0060] In this embodiment, the toothed structure of the rack 42 is located at the top of the rack 42. Positioning the toothed structure at the top of the rack 42 makes the assembly and disassembly of the entire transmission assembly (rack 42 and gear) more convenient when the first gear 23 meshes with the toothed structure of the rack 42 from above. Especially during equipment debugging or replacement of worn parts, the meshing state can be directly observed from above the transmission assembly, facilitating alignment and adjustment, and improving the maintainability and assembly efficiency of the equipment.

[0061] In this embodiment, the driving device 41 is a linear module. Linear modules have the advantages of high motion accuracy, high stability, and high reliability.

[0062] In some other embodiments, the drive device 41 may also be any device such as a cylinder or hydraulic cylinder that can drive the support plate 11 to move along the first horizontal direction X.

[0063] The rack 42 is fixed to the ground or other components by the mounting rod 421 so that the rack 42 is located on one side of the support plate 11 and meshes with the first gear 23.

[0064] Specifically, the linear module includes a second drive motor 411, a support base 412, a transmission screw 413, and a slide block 414. The support base 412 is provided with a limiting groove 4121. The transmission screw 413 passes through the support base 412 along the first horizontal direction X, and at least a portion of the transmission screw 413 is located in the limiting groove 4121. The slide block 414 is sleeved on the transmission screw 413 and threadedly engaged with the transmission screw 413. At least a portion of the slide block 414 is located in the limiting groove 4121. The support plate 11 is connected to the top of the slide block 414. The second drive motor 411 is connected to the transmission screw 413 and can drive the transmission screw 413 to rotate around its central axis.

[0065] The second drive motor 411 is located outside the limiting groove 4121, and the drive motor is connected to the transmission screw 413 through a coupling.

[0066] The slide 414 is provided with a transmission nut that cooperates with the transmission screw 413. The slide 414 is sleeved on the transmission screw 413 through the transmission nut and is threadedly engaged with the transmission screw 413.

[0067] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
