Description

Technical Field

[0001] The present invention relates to the technical field of quartz product processing equipment, and more specifically, to an equipment for grinding a quartz boat. Background Art

[0002] Quartz boat is an important component of semiconductor components. At present, the quartz boat frame is completed by welding the bottom plate and the side plate after processing them separately. After welding, due to the influence of welding accuracy and stress deformation, the verticality between the side plate and the bottom plate of the boat frame cannot meet the use requirements of the product. At this time, it is necessary to manually hold the grinding block, fix the boat frame with the bottom plate as the reference, and then grind the side plate to make the verticality of the two meet the product requirements. However, due to the uneven force of manual grinding on the entire surface, it is often impossible to ensure that the grinding surface of the side plate of the boat frame after grinding is the same plane, and the verticality between the bottom plate cannot be guaranteed. It is necessary to measure and grind again after multiple times, which is labor-intensive and has high work intensity.

[0003] Based on this, it is necessary to develop a device that can automatically grind the quartz boat. Summary of the invention

[0053] The quartz boat frame is mainly composed of a large side plate, a side groove plate and an intermediate groove plate. The large side plate is first placed horizontally, and then the side groove plate and the intermediate groove plate are assembled on the large side plate, followed by welding to form an integrated structure. Since the verticality between the intermediate groove plate and the large side plate after welding is difficult to meet the product's use requirements, the intermediate groove plate needs to be polished. In order to improve the polishing accuracy, this application provides an automatic grinding device.

[0054] The following embodiments are used to describe in detail a processing device for quartz products of the present application.

[0055] Embodiment 1:

[0056] like Figure 1-Figure 6 As shown, in this embodiment, a processing device for quartz products includes: a frame 1, the bottom of which is provided with rollers 11 around to facilitate movement, and the top of which is provided with a workbench 12 for placing products; a clamping assembly 2, which is arranged on the frame 1 and is used to clamp the product on the workbench 12; and a grinding assembly 3, which is arranged on the frame 1 and is used to grind the side of the product on the workbench 12;

[0057] Among them, 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 is opened at its grinding end; and a driving mechanism 32, which is used to drive the grinding block 31 to move so that the grinding block 31 grinds the side of the product.

[0058] The welded quartz boat is placed on the workbench 12, and then the quartz boat is clamped by the clamping assembly 2, and then the driving mechanism 32 is started to drive the grinding block 31 to move back and forth. The grinding sand dropped from the grinding block 31 can achieve uniform grinding of the middle groove plate on the quartz boat under the action of the grinding sand.

[0059] It should be noted that the clamping assembly 2 is a quick-clamping structure. After the quartz boat is placed on the workbench 12, the quick-clamping structure can be used to quickly fix the quartz boat.

[0060] Embodiment 2:

[0061] This embodiment is a further improvement made on the basis of the first embodiment.

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

[0063] In order to prevent the grinding sand from flowing out of the grinding sand hole 311 on the grinding block 31 and then being lost quickly, a groove 312 is provided. Under the action of the groove 312, the grinding sand flowing out of the grinding sand hole 311 will flow into the groove 312. The groove 312 can well retain the grinding sand, thereby reducing the waste of grinding sand.

[0064] It should be noted that the groove 312 is tilted so that the grinding sand in the groove 312 can slowly flow downward under its own gravity, and then continuously act on the middle groove plate of the quartz boat to achieve continuous grinding of the middle groove plate.

[0065] Embodiment three:

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

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

[0068] The outlet end of the grinding sand cylinder 33 is connected to the chamber of the grinding block 31 for conveying 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. A large amount of grinding sand can be stored in the grinding sand cylinder 33, and then the grinding block 31 is loaded by the grinding sand cylinder 33, which greatly reduces the loading time of the staff.

[0070] It should be noted that since the abrasive sand has low fluidity and is relatively dense, the abrasive sand in the abrasive sand barrel 33 is easily deposited at the bottom and then blocks the outlet. For this reason, an agitator 34 is provided in the abrasive sand barrel 33. Under the stirring action of the agitator 34, the abrasive sand can flow and avoid deposition.

[0071] In this embodiment, in order to optimize and prevent the grinding sand from falling onto the ground after flowing out of the grinding block 31, a grinding sand recovery box 35 is provided. The grinding sand recovery box 35 is installed on the frame 1 to collect the grinding sand flowing out of the grinding block 31 to avoid waste and facilitate cleaning.

[0072] Embodiment 4:

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

[0074] like Figure 4-Figure 6 As shown, the driving mechanism 32 includes: a first slide rail 321, horizontally arranged on the workbench 12; a mounting frame 322, slidably arranged on the first slide rail 321, used to move closer to or away from the product on the workbench 12; a first power unit 323, used to drive the mounting frame 322 to move on the first slide rail 321; a second slide rail 324, vertically arranged on the mounting frame 322, and the grinding block 31 is slidably arranged on the second slide rail 324; and a second power unit 325, used to drive the grinding block 31 to move on the second slide rail 324.

[0075] In order to automatically grind the quartz boat, this can be achieved by driving the grinding block 31 to perform linear reciprocating motion. During the grinding process, if the grinding block 31 is only reciprocated up and down, there will be a problem of insufficient grinding. For this reason, an external force is required on the grinding block 31 so that the grinding block 31 always acts on the quartz boat, so that sufficient grinding can be achieved.

[0076] Specifically, during grinding, the grinding block 31 is driven by the second power unit 325 to make up and down reciprocating motion, the grinding sand flows out from the grinding block 31, and then rubs on the quartz boat frame to achieve grinding. At the same time, the first power unit 323 needs to drive the mounting frame 322 to move, so as to drive the grinding block 31 to move toward 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 is to improve the verticality 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 bottom plate 3221. The mounting bottom plate 3221 is slidably arranged on the first slide rail 321, and the second slide rail 324 is vertically arranged on the mounting side plate 3222.

[0078] In this embodiment, the driving mechanism 32 is optimized and also includes: a first limit sensor unit 326, which is used to control the operating state of the first power unit 323 to control the moving position of the mounting frame 322; and a second limit sensor unit 327, which is used to control 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 is fully ground, it is necessary to control the first power unit 323 to stop running to avoid further grinding. Therefore, a first limit sensor unit 326 is provided. After the mounting frame 322 moves to a certain position, that is, after the grinding block 31 moves to a certain position, the first limit sensor 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 middle groove plate on the quartz boat frame, so the moving path of the grinding block 31 needs to cover the middle groove plate. For this purpose, a second limit sensor unit 327 is provided. There are two second limit sensor units 327, which are respectively provided upper and lower to control the uppermost position and the lowermost position of the grinding block 31. When the grinding block 31 moves to be detected by the second limit sensor unit 327 above, 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 be detected by the second limit sensor unit 327 below, the second power unit 325 drives the grinding block 31 to move upward again. In this way, the reciprocating motion of the grinding block 31 is realized.

[0080] In this embodiment, the first power unit 323 is optimized to include: a threaded rod 3231, one end of which is arranged on the mounting frame 322, and the other end is threadedly connected to the frame 1, when the threaded rod 3231 rotates, the threaded rod 3231 moves the mounting frame 322 closer to or away from the product on the workbench 12; and a first motor 3232, which is used to drive the threaded rod 3231 to rotate;

[0081] A torque limiter is further 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 value set by the torque limiter, the output end of the torque limiter idles to stop the threaded rod 3231 from rotating.

[0082] In order to drive the mounting frame 322 to move, a threaded rod 3231 is provided on the mounting frame 322, and the threaded rod 3231 can rotate on the mounting frame 322, and the other end of the threaded rod 3231 is threadedly connected to the frame 1. When the threaded rod 3231 is rotated, the threaded rod 3231 extends into the frame 1 or extends from the frame 1, and at the same time drives the mounting frame 322 to move synchronously. Specifically, the threaded rod 3231 is driven to rotate by the first motor 3232 to achieve this. In order to make the grinding block 31 grind the quartz boat frame evenly, the force exerted by the grinding block 31 on the quartz boat frame needs to be kept constant. Based on this, a torque limiter is provided to limit the output torque of the first motor 3232, thereby maintaining a stable pressure. The first motor 3232 rotates continuously during the grinding process. Since the 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 is in a slipping state, and the first motor 3232 cannot drive the grinding block 31 forward, but only provides a forward thrust, thereby ensuring the stability of the grinding pressure.

[0083] It should be noted that the first power unit 323 further includes: a first transmission pulley set 3233, and the first transmission pulley set 3233 is used to connect the end of the threaded rod 3231 close to the mounting frame 322 with the torque limiter.

[0084] It should be noted that the second power unit 325 includes: a second transmission pulley group 3251, the grinding block 31 is connected to the belt on the second transmission pulley group 3251 through a connecting piece; and a second motor 3252, which is used to drive the second transmission pulley group 3251 to operate, so that the second transmission pulley group 3251 drives the grinding block 31 to move upward or downward.

[0085] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
