Description

Technical Field

[0001] This invention relates to a semiconductor processing clamping fixture, and more specifically, to an automatic punching fixture for quartz nipples. Background Technology

[0002] Currently, the quartz processing industry produces a type of small nipple product with several rows of evenly distributed holes on its top. In previous processing methods, the fixture holding the product had to be manually adjusted to a certain position, then a hole was drilled using laser equipment. This process was repeated until the entire product was completed. This operation was extremely complex, time-consuming, and labor-intensive. Furthermore, manual operation meant that operator negligence could lead to hole misalignment, resulting in a defective product. Summary of the Invention

[0003] To overcome the above shortcomings, the present invention provides an automatic drilling fixture for quartz nipples, which can automatically adjust the posture of the quartz nipple during the drilling process, reducing labor intensity and ensuring the accuracy of the hole position.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an automatic punching fixture for quartz nipples, comprising a rotating seat rotatably mounted on a base, the rotating seat being able to automatically rotate horizontally, a clamping chuck being rotatably mounted on the rotating seat, the clamping chuck being able to automatically rotate vertically, and a plurality of jaws being provided on the clamping chuck, the jaws moving radially to clamp the quartz nipples.

[0005] During the drilling operation, the quartz nipple is clamped onto the chuck and positioned by the jaws. The laser drilling head is positioned above the chuck. Through the horizontal rotation of the rotating base and the vertical rotation of the chuck, the laser beam strikes the quartz nipple from the normal direction onto its surface during drilling. The automatic rotation of the rotating base and chuck adjusts the orientation of the quartz nipple; once the orientation is correct, the laser drilling operation is performed. This reduces labor intensity and ensures drilling accuracy.

[0006] Preferably, a vertical rotary motor is installed on the base, which drives the rotating seat to rotate; a horizontal rotary motor is installed on the rotating seat, which drives the clamping chuck to rotate.

[0007] The vertical rotary motor enables the automatic rotation of the rotating seat, and the horizontal rotary motor enables the automatic rotation of the clamping chuck, which facilitates precise control of the rotation angle of the rotating seat and the clamping chuck, and helps to ensure the accuracy of the hole position.

[0008] As a preferred embodiment, a pin is provided in the middle of the clamping chuck, and a support surface is provided at the bottom of the pin. The quartz nipple is fitted and inserted into the pin, and the lower end of the quartz nipple is supported on the support surface.

[0009] The quartz nipple is cap-shaped with a recessed hole. The pins on the clamping chuck are designed to fit into the recessed hole of the quartz nipple, facilitating radial positioning during clamping. The support surfaces on the pins provide stable support for the quartz nipple.

[0010] Preferably, the inner end of the claw is connected to the pressure block, and the lower end of the quartz nipple is provided with a flange, which is pressed onto the flange by the pressure block.

[0011] The pressure block design enables the axial positioning of the quartz nipple.

[0012] Preferably, a pre-tightening column is installed on the lower surface of the pressure block, a pre-tightening spring is installed between the pre-tightening column and the pressure block, and an inclined guide surface is provided on the lower end face of the pre-tightening column.

[0013] The preload spring provides preload force to the preload pin, causing the lower end of the preload pin to abut against the flange, thus achieving axial positioning of the quartz nipple. The guide surface facilitates the lower end of the preload pin sliding into the upper surface of the flange.

[0014] Preferably, a positioning block is installed on the clamping chuck, a telescopic rod is installed on the positioning block, a telescopic spring is installed between the telescopic rod and the positioning block, and a notch is provided on the outer wall of the quartz nipple, with the end of the telescopic rod abutting against the notch.

[0015] One type of quartz nipple that needs to be drilled has a notched plane on its outer wall. In order to ensure the accuracy of the relative position between the notched plane and the hole, the notched plane needs to be positioned. During the positioning operation, the telescopic rod moves radially inward so that the end of the telescopic rod abuts against the notched plane, and the telescopic spring provides clamping force to the telescopic rod.

[0016] Another option involves installing a positioning block on the clamping chuck, a telescopic rod on the positioning block, and a notch on the outer wall of the quartz nipple; at least three push rods are installed at the front end of the telescopic rod, with the ends of the push rods all able to touch the notch; a positioning spring is installed between the push rods and the telescopic rod; a spacing sensor is installed on the telescopic rod, which detects the distance between the ends of the push rods and the telescopic rod; and a drive wheel driven by a motor is installed at the end of the telescopic rod, which can fit against the outer wall of the quartz nipple.

[0017] When the quartz nipple is first loaded into the clamping chuck, the notch plane is usually slightly off-center. At this time, the telescopic rod moves inward, and the push rods mounted on the telescopic rod can reach the notch plane. When the notch plane position deviation is small, the push rods can fine-tune the quartz nipple to the accurate position. When the notch plane position deviation is large, the push rod ends reach the outer wall of the quartz nipple or the notch plane. At this point, the spacing sensor detects a large deviation in the distance between each push rod end and the telescopic rod, indicating a large notch plane position deviation. The drive wheel then engages with the outer wall of the quartz nipple, and the motor drives the drive wheel to rotate. The rotation of the drive wheel causes the quartz nipple to rotate, adjusting its posture. During the posture adjustment process, the spacing sensor continuously monitors the distance between each push rod end and the telescopic rod. When the distances between all push rod ends and the telescopic rod are consistent, the posture adjustment is considered complete. This structural design achieves posture adjustment of the quartz nipple, ensuring clamping accuracy. The posture adjustment process is automatic, accurate, reliable, and reduces labor intensity.

[0018] Preferably, a tension spring is installed between the telescopic rod and the positioning block, a rotatable locking sleeve is installed on the telescopic rod, a locking block is provided on the locking sleeve, and a locking groove is provided on the positioning block. The rotation of the locking sleeve causes the locking block to engage in the locking groove to achieve positioning of the telescopic rod.

[0019] Before the quartz nipple is loaded, the locking block disengages from the locking groove. Under the action of the tension spring, the front end of the telescopic rod moves backward to avoid interference during the clamping process of the quartz nipple. After the quartz nipple is loaded, push the telescopic rod forward and rotate the locking sleeve to lock the locking block into the locking groove to position the telescopic rod. At this time, the drive wheel is in contact with the outer wall of the quartz nipple.

[0020] Compared with the prior art, the beneficial effects of the present invention are: (1) The automatic drilling fixture for quartz nipples in this patent application can automatically adjust the posture of the quartz nipples during the drilling process, reducing labor intensity and ensuring the accuracy of the hole position; (2) The quartz nipples can achieve circumferential and axial positioning during clamping, and the clamping positioning is reliable; (3) The quartz nipples can achieve rotational posture adjustment during clamping, ensuring the accuracy of the clamping position.

[0026] The technical solution of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0027] Example 1: An automatic punching fixture for quartz nipples (see attached document) Figure 1 To be continued Figure 3 The system includes a rotating seat 2 rotatably mounted on a base 1, which can automatically rotate horizontally. A vertical rotary motor 3 is mounted on the base, driving the rotating seat to rotate. The base is fixedly mounted on a worktable 4. A clamping chuck 5 is rotatably mounted on the rotating seat, which can automatically rotate vertically. A horizontal rotary motor 6 is mounted on the rotating seat, driving the clamping chuck to rotate. The clamping chuck and the horizontal rotary motor are suspended in the air. The clamping chuck is provided with several jaws 7, three of which are evenly distributed. The jaws move radially to clamp the quartz nipple 8. The radial movement of the jaws is achieved by rotating screws mounted on the side wall of the clamping chuck. The connection structure between the clamping chuck and the jaws is existing technology and will not be described in detail in this paper.

[0028] A pin 9 is provided in the middle of the clamping chuck, and a support surface 10 is provided at the bottom of the pin. The quartz nipple is fitted into the pin and inserted, with its lower end supported on the support surface. A pressure block 11 is connected to the inner end of the jaws. A flange 12 is provided at the lower end of the quartz nipple. A protrusion 13 is provided on the inner wall of the pressure block. The protrusion on the pressure block presses against the flange, and the side wall of the pressure block is used to clamp the side wall of the flange.

[0029] A positioning block 14 is installed on the clamping chuck, a telescopic rod 15 is installed on the positioning block, and a telescopic spring 16 is installed between the telescopic rod and the positioning block. A notch plane 17 is provided on the outer wall of the quartz nipple, and the end of the telescopic rod abuts against the notch plane to position the quartz nipple.

[0030] During the drilling operation, the quartz nipple is clamped onto the clamping chuck. Before loading the quartz nipple, the telescopic rod is pulled back. After the quartz nipple is loaded into the clamping chuck, the telescopic rod is released. Under the action of the telescopic spring, the telescopic rod returns to its original position, and its front end rests against the outer wall of the flange. For quartz nipples with a notched surface on the outer wall, the end of the telescopic rod rests against the notched surface to position the quartz nipple. Then, the jaws move radially to reliably clamp the quartz nipple. The laser drilling head 35 is positioned above the clamping chuck. Through the horizontal rotation of the rotating seat and the vertical rotation of the clamping chuck, the laser beam is directed onto the quartz nipple from the normal direction of its surface during drilling. The automatic rotation of the rotating seat and clamping chuck adjusts the posture of the quartz nipple. After the posture is adjusted, the laser drilling operation is performed, which reduces labor intensity and ensures drilling accuracy.

[0031] Example 2: An automatic punching fixture for quartz nipples (see attached document) Figure 4 Its structure is similar to that of Embodiment 1, with the main difference being that a pre-tightening post 18 is installed on the lower surface of the pressure block in this embodiment. The pre-tightening post is installed on a protrusion on the pressure block, and a pre-tightening spring 19 is installed between the pre-tightening post and the protrusion on the pressure block. An inclined guide surface 20 is provided on the lower end face of the pre-tightening post. A positioning block is installed on the clamping chuck, and a telescopic rod is installed on the positioning block. The telescopic rod is radially arranged, and a notch plane is provided on the outer wall of the quartz nipple. At least three push rods 21 are installed at the front end of the telescopic rod. In this embodiment, three push rods are provided, all of which are parallel to the telescopic rod, and the ends of the push rods can touch the notch plane. A positioning spring 22 is installed between the push rod and the telescopic rod. A spacing sensor 23 is installed on the telescopic rod, which detects the spacing between the ends of the push rods and the telescopic rod. A mounting hole 24 is provided on the telescopic rod corresponding to the push rod. An end cap 25 is provided at the opening end of the mounting hole, and a limiting head 26 is provided at the end of the push rod. The limiting head abuts between the positioning spring and the end cap, and the front end of the push rod extends out of the end cap. The positioning spring is installed in the mounting hole, and the spacing sensor is installed at the bottom of the mounting hole. A drive wheel 28, driven by a motor 27, is installed at the end of the telescopic rod. A belt drive connects the motor output shaft and the drive wheel, allowing the drive wheel to fit snugly against the outer wall of the quartz nipple. A controller is mounted on the telescopic rod, with its output connected to the motor. Spacing sensors are connected to the controller's input. The controller controls the motor's operation based on signals transmitted from the spacing sensors.

[0032] A tension spring 29 is installed between the telescopic rod and the positioning block. A rotatable locking sleeve 30 is installed on the telescopic rod. A connecting shaft 31 is provided at the outer end of the telescopic rod. The locking sleeve is rotatably fitted onto the outside of the connecting shaft. A locking block 32 is provided on the locking sleeve, and a locking groove 33 is provided on the positioning block. The rotation of the locking sleeve causes the locking block to engage with the locking groove, thereby positioning the telescopic rod. An insertion hole 34 is provided on the positioning block. The telescopic rod has a rectangular cross-section and is fitted into the insertion hole. The telescopic rod and the insertion hole can only move axially and cannot rotate relative to each other. Other structures are the same as in Embodiment 1.

[0033] Before loading the quartz nipple, the locking block disengages from the locking groove. Under the action of the tension spring, the front end of the telescopic rod moves backward to avoid interference during the clamping process. After the quartz nipple is loaded, push the telescopic rod forward and rotate the locking sleeve to engage the locking block in the locking groove, thus positioning the telescopic rod. At this time, the drive wheel is in contact with the outer wall of the quartz nipple. When the quartz nipple is first loaded into the clamping chuck, the notch plane is usually slightly off-center. At this time, the telescopic rod moves inward, and the push rods mounted on the telescopic rod can reach the notch plane. When the notch plane position deviation is small, the quartz nipple can be finely adjusted to the accurate position by the action of multiple push rods. When the notch plane position deviation is large, the end of the push rod abuts against the outer wall of the quartz nipple or the notch plane. At this time, the spacing sensor detects a large deviation in the distance between each push rod end and the telescopic rod, indicating a large deviation in the notch plane position. The drive wheel then engages with the outer wall of the quartz nipple, and the motor drives the drive wheel to rotate. The rotation of the drive wheel causes the quartz nipple to rotate, adjusting its posture. During the posture adjustment process, the spacing sensor continuously monitors the distance between each push rod end and the telescopic rod. When the distances between all push rod ends and the telescopic rod are consistent, the posture adjustment is considered complete. This structural design achieves posture adjustment of the quartz nipple, ensuring clamping accuracy. The posture adjustment process is automatic, accurate, reliable, and reduces labor intensity.
