Description

Technical Field

[0001] This invention relates to the field of quartz product processing equipment technology, and more specifically, to an apparatus for grinding quartz boat frames. Background Technology

[0002] Quartz boats are an important component in semiconductor parts. Currently, quartz boat frames are assembled by separately machining the base plate and side plates and then welding them together. After welding, due to factors such as welding accuracy and stress deformation, the perpendicularity between the side plates and the base plate of the boat frame may not meet the product's usage requirements. In this case, manual grinding blocks are needed to fix the boat frame with the base plate as a reference and grind the side plates to ensure that the perpendicularity meets the product requirements. However, because manual grinding involves uneven force across the entire surface, it is often impossible to ensure that the ground surfaces of the side plates of the boat frame are on the same plane after grinding, and the perpendicularity with the base plate cannot be guaranteed. Multiple measurements and re-grinding are required, resulting in a large workload and high work intensity.

[0003] Therefore, it is necessary to develop a device that can automatically grind quartz boat frames. Summary of the Invention

[0004] The main objective of this invention is to provide a processing device for quartz products to solve the technical problems mentioned in the background art.

[0005] To address the aforementioned technical problems, this invention proposes a processing device for quartz products, comprising:

[0006] A frame, which has a worktable for placing products;

[0007] Clamping assembly, mounted on the frame, is used to clamp products located on the worktable;

[0008] And a grinding assembly, mounted on the frame, for grinding the sides of the product on the worktable;

[0009] The grinding components include:

[0010] The grinding block has a cavity inside for storing grinding sand, and its grinding end has a grinding sand hole that communicates with the cavity;

[0011] And a drive mechanism, used to drive the grinding block to reciprocate in the vertical direction so that the grinding block grinds the side of the product.

[0012] In the above technical solution, furthermore, a groove is provided on the grinding end of the grinding block, located below the grinding sand hole, and the groove is inclined.

[0013] In any of the above technical solutions, the grinding component further includes:

[0014] A grinding sand container, used to store grinding sand;

[0015] And a stirrer, used to stir the grinding sand in the grinding sand cylinder;

[0016] The outlet end of the grinding sand cylinder is connected to the chamber of the grinding block and is used to deliver grinding sand into the grinding block.

[0017] In any of the above technical solutions, the grinding component further includes:

[0018] The abrasive collection box, located on the frame, is used to collect the abrasive that flows out of the abrasive blocks.

[0019] In any of the above technical solutions, the driving mechanism further includes:

[0020] The first slide rail is horizontally set on the worktable;

[0021] The mounting bracket is slidably mounted on the first slide rail and is used to move the product closer to or away from the worktable.

[0022] The first power unit is used to drive the mounting bracket to move on the first slide rail;

[0023] The second slide rail is vertically mounted on the mounting bracket, and the grinding block is slidably mounted on the second slide rail;

[0024] And a second power unit for driving the grinding block to move on the second slide rail.

[0025] In any of the above technical solutions, the driving mechanism further includes:

[0026] The first limit sensing unit is used to control the operating state of the first power unit in order to control the moving position of the mounting bracket.

[0027] And a second limit sensing unit, used to control the operating state of the second power unit so that the grinding block reciprocates on the second slide rail.

[0028] In any of the above technical solutions, the first power unit further includes:

[0029] The threaded rod has one end mounted on the mounting bracket and the other end threadedly connected to the machine frame. When the threaded rod rotates, it moves the mounting bracket toward or away from the product on the worktable.

[0030] And the first motor, used to drive the threaded rod to rotate;

[0031] A torque limiter is also provided between the first motor and the threaded rod. When the output torque of the first motor is greater than the threshold set by the torque limiter, the output end of the torque limiter will idle, so that the threaded rod stops rotating.

[0032] In any of the above technical solutions, the first power unit further includes:

[0033] The first drive pulley assembly is used to connect the end of the threaded rod near the mounting bracket to the torque limiter.

[0038] Beneficial effects: Compared with the prior art, the present invention automatically grinds the sides of quartz boat frame products by driving the grinding block to reciprocate automatically with a motor and coordinating the motor-driven grinding block to feed. The feed position is limited by a sensor to ensure the size of the product. Furthermore, the grinding pressure provided by the motor feed ensures the stability of the pressure, thereby ensuring the flatness of the side plate grinding surface and its perpendicularity to the bottom surface. This solves the problem that current manual grinding cannot guarantee the flatness of the grinding surface and its perpendicularity to the bottom surface. Attached Figure Description

[0053] The quartz boat frame is mainly composed of a large side plate, a side groove plate, and a middle groove plate. First, the large side plate is placed horizontally, and then the side groove plate and the middle groove plate are assembled on the large side plate. Then, they are welded to form an integral structure. Since the perpendicularity between the welded middle groove plate and the large side plate is difficult to meet the product's usage requirements, the middle groove plate needs to be ground. To improve the grinding accuracy, this application provides an automatic grinding device.

[0054] The following embodiments will be used to describe in detail a processing device for quartz products according to this application.

[0055] Example 1:

[0056] like Figures 1-6 As shown, in this embodiment, a processing device for quartz products includes: a frame 1 with rollers 11 arranged around its bottom for easy movement, and a worktable 12 for placing products on its top; a clamping assembly 2, disposed on the frame 1, for clamping the products located on the worktable 12; and a grinding assembly 3, disposed on the frame 1, for grinding the sides of the products on the worktable 12.

[0057] The grinding assembly 3 includes: a grinding block 31, which has a chamber for storing grinding sand inside, and a grinding sand hole 311 connected to the chamber at its grinding end; and a driving mechanism 32 for driving the grinding block 31 to move so that the grinding block 31 grinds the side of the product.

[0058] The welded quartz boat frame is placed on the workbench 12, and then the quartz boat frame is clamped by the clamping assembly 2. Then the drive mechanism 32 is started, which drives the grinding block 31 to move back and forth. Through the grinding sand falling on the grinding block 31, the middle groove plate on the quartz boat frame is uniformly ground under the action of the grinding sand.

[0059] It should be noted that the clamping component 2 is a quick-clamp structure. After the quartz boat frame is placed on the worktable 12, the quick-clamp structure can quickly fix the quartz boat frame.

[0060] Example 2:

[0061] This embodiment is a further improvement based on Embodiment 1.

[0062] like Figure 3 and Figure 4 As shown, in this embodiment, the grinding end of the grinding block 31 is also provided with a groove 312 located below the grinding sand hole 311, and the groove 312 is inclined.

[0063] To prevent the abrasive from flowing out of the abrasive holes 311 on the abrasive block 31 and then quickly being lost again, a groove 312 is provided. Under the action of the groove 312, the abrasive flowing out of the abrasive holes 311 will flow into the groove 312. The groove 312 can effectively retain the abrasive and reduce the waste of abrasive.

[0064] It should be noted that the groove 312 is set at an angle so that the abrasive in the groove 312 can flow slowly downward under its own gravity, thereby continuously acting on the middle groove plate of the quartz boat frame to achieve continuous grinding of the middle groove plate.

[0065] Example 3:

[0066] This embodiment is a further improvement based on any of the above embodiments.

[0067] like Figures 1-5 As shown, the grinding assembly 3 also includes: a grinding sand cylinder 33 for storing grinding sand; and a stirrer 34 for stirring the grinding sand in the grinding sand cylinder 33;

[0068] The outlet end of the grinding sand cylinder 33 is connected to the chamber of the grinding block 31 and is used to deliver grinding sand into the grinding block 31.

[0069] In order to continuously supply grinding sand to the grinding block 31, a grinding sand cylinder 33 is provided. The grinding sand cylinder 33 can store a large amount of grinding sand, and then the grinding block 31 is fed by the grinding sand cylinder 33, which greatly reduces the feeding time of the workers.

[0070] It should be noted that, due to the low fluidity and high density of the grinding sand, the grinding sand in the grinding sand cylinder 33 is prone to deposit at the bottom, which can block the outlet. Therefore, an agitator 34 is installed in the grinding sand cylinder 33. Under the stirring action of the agitator 34, the grinding sand can flow and avoid deposit.

[0071] In this embodiment, to prevent the abrasive from flowing out of the abrasive block 31 and falling onto the ground, an abrasive recycling box 35 is provided. The abrasive recycling box 35 is installed on the frame 1 to collect the abrasive flowing out of the abrasive block 31, so as to avoid waste and facilitate cleaning.

[0072] Example 4:

[0073] This embodiment is a further improvement based on any of the above embodiments.

[0074] like Figures 4-6 As shown, the drive mechanism 32 includes: a first slide rail 321, horizontally disposed on the worktable 12; a mounting bracket 322, slidably disposed on the first slide rail 321, for moving closer to or further away from the product on the worktable 12; a first power unit 323, for driving the mounting bracket 322 to move on the first slide rail 321; a second slide rail 324, vertically disposed on the mounting bracket 322, on which the grinding block 31 is slidably disposed; and a second power unit 325, for driving the grinding block 31 to move on the second slide rail 324.

[0075] To automatically grind the quartz boat frame, the grinding block 31 can be driven to make linear reciprocating motion. If the grinding block 31 is only moved up and down during the grinding process, there will be insufficient grinding. Therefore, an external force is needed to the grinding block 31 so that the grinding block 31 is always acting on the quartz boat frame, so that the grinding can be fully achieved.

[0076] Specifically, during grinding, the second power unit 325 drives the grinding block 31 to reciprocate up and down, and the grinding sand flows out from the grinding block 31 and then rubs against the quartz boat frame to achieve grinding. At the same time, the first power unit 323 needs to drive the mounting bracket 322 to move, so as to move the grinding block 31 closer to the quartz boat frame, so that the grinding block 31 is pressed against the quartz boat frame.

[0077] It should be noted that the main purpose of grinding the quartz boat frame is to improve the perpendicularity between the middle groove plate and the large side plate. Therefore, the grinding block 31 needs to move vertically. For this purpose, the mounting frame 322 is divided into a vertical mounting side plate 3222 and a horizontal mounting base plate 3221. The mounting base plate 3221 is slidably mounted on the first slide rail 321, while the second slide rail 324 is vertically mounted on the mounting side plate 3222.

[0078] In this embodiment, the optimized drive mechanism 32 further includes: a first limit sensing unit 326 for controlling the operating state of the first power unit 323 to control the moving position of the mounting bracket 322; and a second limit sensing unit 327 for controlling the operating state of the second power unit 325 to make the grinding block 31 reciprocate on the second slide rail 324.

[0079] After the quartz boat frame has been sufficiently ground, it is necessary to control the first power unit 323 to stop running in order to avoid further grinding. Therefore, a first limit sensing unit 326 is provided. After the mounting frame 322 has moved to a certain position, that is, after the grinding block 31 has moved to a certain position, the first limit sensing unit 326 detects the moving position of the mounting frame 322 or the grinding block 31. At this time, the first power unit 323 stops running, so that the mounting frame 322 stops moving. Similarly, the grinding block 31 needs to grind the entire intermediate groove plate on the quartz boat frame. Therefore, the movement path of the grinding block 31 needs to cover the intermediate groove plate. For this purpose, a second limit sensing unit 327 is provided. There are two second limit sensing units 327, which are set at the top and bottom respectively, to control the uppermost and lowermost positions of the grinding block 31. When the grinding block 31 moves to the point where it is detected by the upper second limit sensing unit 327, the second power unit 325 drives the grinding block 31 to move in the opposite direction, that is, to move downward. When the grinding block 31 moves downward to the point where it is detected by the lower second limit sensing unit 327, the second power unit 325 drives the grinding block 31 to move upward. In this way, the reciprocating motion of the grinding block 31 is realized.

[0080] In this embodiment, the optimized first power unit 323 includes: a threaded rod 3231, one end of which is disposed on the mounting bracket 322 and the other end is threadedly connected to the frame 1. When the threaded rod 3231 rotates, the threaded rod 3231 carries the mounting bracket 322 to move closer to or away from the product on the worktable 12; and a first motor 3232 for driving the threaded rod 3231 to rotate.

[0081] A torque limiter is also provided between the first motor 3232 and the threaded rod 3231. When the output torque of the first motor 3232 is greater than the threshold set by the torque limiter, the output end of the torque limiter will idle, so that the threaded rod 3231 will stop rotating.

[0082] To enable the mounting bracket 322 to move, a threaded rod 3231 is provided on the mounting bracket 322. The threaded rod 3231 can rotate on the mounting bracket 322, and the other end of the threaded rod 3231 is threadedly connected to the frame 1. When the threaded rod 3231 is rotated, it extends into or out of the frame 1, simultaneously driving the mounting bracket 322 to move synchronously. Specifically, this is achieved by the first motor 3232 driving the threaded rod 3231 to rotate. To ensure uniform grinding of the quartz boat frame by the grinding block 31, the force exerted by the grinding block 31 on the quartz boat frame needs to remain constant. Based on this, a torque limiter is provided to limit the output torque of the first motor 3232, thereby maintaining stable pressure. The first motor 3232 rotates continuously during the grinding process. Since a torque limiter is installed on the motor shaft, when the grinding block 31 contacts the quartz boat frame and reaches a certain pressure, the torque limiter slips, and the first motor 3232 cannot drive the grinding block 31 forward, but only provides a forward thrust, thus ensuring the stability of the grinding pressure.

[0083] It should be noted that the first power unit 323 also includes a first transmission pulley set 3233, which is used to connect the end of the threaded rod 3231 near the mounting bracket 322 to the torque limiter.

[0084] It should be noted that the second power unit 325 includes: a second transmission pulley assembly 3251, the grinding block 31 being connected to the belt on the second transmission pulley assembly 3251 via a connector; and a second motor 3252 for driving the second transmission pulley assembly 3251 to run, so that the second transmission pulley assembly 3251 drives the grinding block 31 to move upward or downward.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
