[0088] The quartz claw 100 is mainly composed of a shaft rod 110 and a supporting claw 120 arranged on the shaft rod 110. The shaft rod 110 is uniformly distributed on the upper end (front end) of the shaft rod 110 in the circumferential direction, used for bearing and fixing the wafer. The number of supporting claws 120 is generally N, 3≤N≤6, which is selected according to different needs. Since the existing equipment for producing quartz claws 100 can only produce the same type of quartz claws 100, the universality is low, and therefore it needs to be improved.

[0089] The automatic welding equipment for processing quartz claws and the welding method thereof according to the present application will be described in detail below through the following embodiments.

[0090] Embodiment One:

[0091] As shown in Figure 1 , Figure 2 In this embodiment, an automatic welding equipment for processing quartz claws is provided, which comprises a rack 1, a concentric shaft clamping assembly 2 arranged on the rack 1 and used for clamping a horizontally arranged shaft 110, the concentric shaft clamping assembly 2 being also capable of driving the shaft 110 thereon to rotate, a support claw clamping assembly 3 arranged on the rack 1 and used for clamping a quartz claw 120 and driving the quartz claw 120 to move towards or away from the front end of the shaft 110 so as to butt the support claw 120 with the shaft 110, and a welding gun assembly 4 used for welding the butted support claw 120 with the shaft 110.

[0092] The concentric shaft clamping assembly 2 not only can stably clamp the shaft in the horizontal direction, but also can drive the shaft to rotate, and then make the support claw butt with the shaft accurately under the action of the support claw clamping assembly 3, and then heat the welding surface by the welding gun assembly 4, so as to realize the fusion of the shaft with the support claw. When it is needed to weld the next support claw on the shaft, the shaft is rotated to reach a preset angle, for example, 120° (for three-claw quartz claws), 60° (for six-claw quartz claws) or any angle, so as to realize the processing of different types of quartz claws such as three-claw and six-claw quartz claws.

[0093] Embodiment Two:

[0094] This embodiment is a further improvement based on Embodiment One.

[0095] As shown in Figures 1-5 In this embodiment, the rack 1 is provided with a side plate; the concentric shaft clamping assembly 2 comprises a mounting frame 21 arranged on the side plate, a concentric shaft 22 which is a hollow structure and is arranged horizontally on the mounting frame 21, and two clamping portions 23 which are arranged at two ends of the concentric shaft 22 respectively, and after the shaft is embedded into the concentric shaft 22, the two clamping portions 23 clamp the portions of the shaft at the two ends of the concentric shaft 22 respectively.

[0096] The concentric shaft 22 is arranged on the mounting frame 21 and can rotate around its axis as the center.

[0097] First, the tail of the shaft is inserted into the concentric shaft 22; then, the clamping part 23 is operated to clamp the inserted end of the shaft, and since the concentric shaft 22 can rotate freely around its axis, the shaft can be conveniently rotated, and the verticality of the shaft to the horizontal plane can be guaranteed, greatly improving the work efficiency and machining precision.

[0098] In this embodiment, it should be noted that the mounting frame 21 includes a first flange 211, a second flange 212, and a connecting column 213 connecting the first flange 211 and the second flange 212.

[0099] The first flange 211 and the second flange 212 are provided with bearings in the middle, and the concentric shaft 22 is arranged on the first flange 211 and the second flange 212 through the bearings, and the two ends thereof pass through and extend out of the first flange 211 and the second flange 212.

[0100] The first flange 211 and the second flange 212 are the main load-bearing and positioning components of the mounting frame 21, and are tightly connected through the connecting column 213 to form a stable support frame. The bearings are important components of the mounting frame 21, and are respectively arranged in the middle of the first flange 211 and the second flange 212 to support the concentric shaft 22 and allow it to rotate freely around the axis.

[0101] Through the ingenious combination and accurate installation of the first flange 211, the second flange 212, the connecting column 213, and the bearings, the concentric shaft 22 can be ensured to be stable, accurate, and reliable during rotation.

[0102] In this embodiment, the two ends of the concentric shaft 22 are provided with tapered grooves, and the diameters of the tapered grooves gradually decrease from the outside to the inside; the clamping part 23 includes a collet 231 having a hollow chamber for the shaft to pass through, both ends of which are tapered structures, and one end of which is matched with the tapered groove and is embedded in the tapered groove, and the other end is located outside the tapered groove; and a nut 232, one end of which is a threaded hole and is threadedly connected with the end outer wall of the concentric shaft 22, and the other end of which is a tapered hole and is matched with the tapered structure of the end of the collet 231 extending out of the concentric shaft 22.

[0103] The two ends of the collet 231 are provided with openings 2311, so that the diameter of the hollow chamber of the collet 231 can be reduced when it is squeezed by the nut 232 and the concentric shaft 22, so as to clamp the shaft.

[0104] The clamping portion 23 can effectively clamp the shaft rod through the cooperation of the concentric shaft 22, the tapered groove, the collet 231 and the nut 232. The design is not only simple in structure, but also convenient to operate. The shaft rod can be clamped or loosened by rotating the nut 232, which is very suitable for the application scenario of quartz jaw machining.

[0105] Specifically, after the shaft rod is inserted into the concentric shaft 22, the nut 232 is rotated, and when the inner wall of the tapered hole on the nut 232 abuts against the tapered surface on the upper end of the collet 231 and an external force is applied, the collet 231 moves into the concentric shaft 22. During the movement, the inside of the collet 231 gradually narrows and abuts against the shaft rod, thereby clamping the shaft rod.

[0106] It should be noted that the openings 2311 are multiple and distributed along the circumferential direction of the collet 231. By providing multiple openings 2311, the outer wall of the collet 231 can easily deform under the extrusion of the outside (the nut 232) to clamp the shaft rod.

[0107] It should be noted that the outer wall of the nut 232 is provided with knurling to facilitate the rotation of the nut 232 by the staff.

[0108] It should be noted that the outer wall of the collet 231 is also provided with a radially inward annular groove 2312, which is located between the two tapered structures. This setting facilitates the collet 231 to clamp the shaft rod more effectively.

[0109] It should be noted that the concentric shaft 22 can be provided in a split type, i.e., composed of two shaft portions, for the convenience of machining.

[0110] Embodiment Three:

[0111] This embodiment is a further improvement based on Embodiment Two.

[0112] As shown in Figure 2 , Figure 5 In this embodiment, the concentric shaft clamping assembly 2 further includes a first driving portion 24 for driving the concentric shaft 22 to rotate. The first driving portion 24 includes a motor 241 provided on the side plate, a main gear 242 provided on the output shaft of the motor 241, a driven gear 243 sleeved on the concentric shaft 22, and a synchronous belt 244 sleeved on the main gear 242 and the driven gear 243.

[0113] When the motor 241 drives the main gear 242 to rotate, the synchronous belt 244 drives the driven gear 243 to rotate, thereby driving the concentric shaft 22 to rotate.

[0114] The motor 241 drives the main gear 242 to rotate, and then the driven gear 243 rotates under the action of the synchronous belt 244, and then the concentric shaft 22 also rotates synchronously, thereby accurately controlling the rotation angle of the shaft rod.

[0115] In the embodiment, the optimized and automatic welding device further comprises a fine adjustment sliding table 5 arranged behind the concentric shaft clamping assembly 2, used for fine adjustment of the shaft rod on the concentric shaft clamping assembly 2 in the axial direction thereof.

[0116] The horizontal position of the shaft rod is controlled by the fine adjustment sliding table 5, so that the shaft rod is accurately docked with the support claw. Specifically, after adjusting the support claw clamping assembly 3 so that the support claw thereon is docked with the shaft rod, the two nuts 232 on the concentric shaft 22 are slightly loosened, and then the fine adjustment sliding table 5 is manually adjusted. The extension shaft on the fine adjustment sliding table 5 moves to apply a pushing force to the shaft rod to slightly move the shaft rod. After the shaft rod is accurately docked with the support claw, the nuts 232 are tightened.

[0117] Embodiment Four

[0118] The embodiment is further improved on the basis of any of the above embodiments.

[0119] As shown in Figure 2 , Figure 6 In the embodiment, the support claw clamping assembly 3 comprises a first translation base plate 31 vertically arranged and movably arranged on the rack 1 in the horizontal direction, a second driving part 32 for driving the first translation base plate 31 to move, a lifting base plate 33 vertically arranged and movably arranged on the first translation base plate 31 in the vertical direction, a third driving part 34 for driving the lifting base plate 33 to move, and a support claw clamp 35 arranged on the lifting base plate 33 for clamping the support claw.

[0120] To facilitate the staff to install the support claw on the support claw clamp 35 and to facilitate the control of the movement of the support claw clamp 35 to dock the support claw with the shaft rod, the first translation base plate 31 and the lifting plate 451 are provided. First, the first translation base plate 31 is driven by the second driving part 32 to move away from the shaft rod, and then the support claw is installed on the support claw clamp 35. Then the first translation base plate 31 moves reversely to move close to the front end of the shaft rod. After the support claw moves to the position directly below the front end of the shaft rod, the third driving part 34 is started to move the lifting plate 451 upward, thereby docking the support claw with the bottom of the front end of the shaft rod. Then the support claw or the shaft rod is finely adjusted to accurately dock the two.

[0121] It should be noted that the rack 1 or the first translation base plate 31 has a first guide rod or a first sliding rail horizontally arranged, and the first translation base plate 31 is slidably connected with the rack 1 through the first guide rod or the first sliding rail.

[0122] The first translation base plate 31 or the lifting base plate 33 is provided with a second guide rod or a second sliding rail arranged vertically, and the lifting base plate 33 is slidably connected to the first translation base plate 31 through the second guide rod or the second sliding rail.

[0123] Through the above arrangement, the first translation base plate 31 and the lifting plate 451 are not easy to deviate when moving. For the convenience of arrangement, the embodiment preferably provides the first guide rod on the rack 1 and the second sliding rail on the lifting base plate 33 to realize the movement of the first translation base plate 31 and the lifting base plate 33.

[0124] It should be noted that the second driving part 32 is a pneumatic cylinder, a hydraulic cylinder, an electric cylinder or a linear motor 241, and the third driving part 34 is a pneumatic cylinder, a hydraulic cylinder, an electric cylinder or a linear motor 241. The second driving part 32 is used to accurately control the movement of the supporting claw, so that the supporting claw can be accurately connected with the shaft rod.

[0125] Embodiment five:

[0126] The embodiment is further improved on the basis of the fourth embodiment.

[0127] As shown in Figure 2 In the embodiment, the welding gun assembly 4 includes a second translation base plate 41 arranged vertically and slidably connected to the rack 1 through a first guide rod or a first sliding rail, a fourth driving part 42 for driving the second translation base plate 41 to move, a gun rack upright plate 43 arranged on the second translation base plate 41, and two welding guns 44 symmetrically arranged on the gun rack upright plate 43 for heating the welding surfaces on both sides of the shaft rod and the supporting claw.

[0128] The fourth driving part 42 is arranged on the first translation base plate 31 and the second translation base plate 41, and the second translation base plate 41 moves synchronously when the first translation base plate 31 moves.

[0129] In order to make the flame on the welding gun 44 quickly act on the entire welding surface between the shaft rod and the supporting claw, two oppositely arranged welding guns 44 are arranged, and the two welding guns 44 are used to heat the two sides of the shaft rod and the supporting claw. Then, the fourth driving part 42 drives the second translation base plate 41 to move linearly, so that the two welding guns 44 heat the two sides of the shaft rod and the supporting claw in the horizontal direction, so that the two sides are evenly heated and welded. By arranging two welding guns 44, the welding efficiency of the shaft rod and the supporting claw is effectively improved.

[0130] For the convenience of control and the improvement of the integration of the whole device, the second sliding plate 41 is arranged to slide on the first guide rod or the first slide rail, and the first sliding plate 31 and the second sliding plate 41 are linked through the fourth driving part 42, so that the second sliding plate 41 can move together when the first sliding plate 31 moves, but the first sliding plate 31 does not move when the second sliding plate 41 moves, thereby facilitating the loading of the supporting claw clamping assembly 3.

[0131] Specifically, the fourth driving part 42 is a gas cylinder, a hydraulic cylinder or an electric cylinder, and is installed on the first sliding plate 31, and the piston rod end thereof is installed on the second sliding plate 41.

[0132] It should be noted that the welding gun 44 uses oxyacetylene flame as fuel to heat the shaft and the supporting claw.

[0133] Embodiment six:

[0134] This embodiment is a further improvement based on embodiment five.

[0135] As shown in Figure 2 , Figure 7 , Figure 8 In this embodiment, the two welding guns 44 are arranged to rotate on the gun stand upright plate 43; the welding gun assembly 4 further comprises: a fifth driving part 45 for driving the two welding guns 44 to rotate simultaneously; the fifth driving part 45 comprises: a lifting plate 451 arranged to move in the vertical direction on the gun stand upright plate 43; two racks 452 arranged on both sides of the lifting plate 451; two gears 453 arranged on the two welding guns 44 respectively; and a power member 454 for driving the lifting plate 451 to move up and down.

[0136] Among them, the two gears 453 are respectively engaged with the two racks 452; after the power member 454 drives the lifting plate 451 to move, the two racks 452 drive the two gears 453 to rotate in opposite directions respectively, so as to adjust the angle of the two welding guns 44 to spray fire.

[0137] In order to further improve the welding effect between the shaft and the supporting claw, the welding gun can be controlled to swing up and down to heat the shaft and the supporting claw, specifically, by controlling the rotation of the welding gun.

[0138] In order to make the two welding guns 44 swing up and down simultaneously, the gear 453 and the rack 452 are used for control, when the fifth driving part 45 drives the lifting plate 451 to move up or down, the rack 452 drives the gears 453 on both sides to rotate in opposite directions, so that the rotating directions of the two welding guns 44 are opposite, thereby realizing the synchronous swinging of the welding gun 44.

[0139] Embodiment seven:

[0140] This embodiment is a further improvement based on any of the above embodiments.

[0141] As shown in Figure 1 , Figure 2 and Figure 9 In this embodiment, it also includes: a shaft rod anti-offset component 6, which is used to prevent the upward offset of the front end of the shaft rod after the support claw is docked with the front end of the shaft rod from bottom to top; wherein the shaft rod anti-offset component 6 includes: a bounce detection part 61 for detecting the bounce value of the shaft rod; and a limiting part 62 for limiting the upward movement of the front end of the shaft rod.

[0142] In order to avoid unqualified raw material shaft rods, and excessive upward external force applied by the support claw to the shaft rod when the support claw is docked with the shaft rod, which leads to the upward offset of the shaft rod, and further causes the quartz claw processed subsequently to be scrapped, the shaft rod anti-offset component 6 is provided.

[0143] Specifically, after the shaft rod is clamped by the concentric shaft clamping component 2, it is first detected by the bounce detection part 61 whether the shaft rod is qualified, if so, the next step is performed, otherwise, it needs to be checked whether the shaft rod is offset during installation or the shaft rod itself is unqualified and needs to be replaced. After the shaft rod is detected to be qualified, the position of the limiting part 62 is adjusted, that is, the limiting part 62 is placed above the front end of the shaft rod, and after that, when the support claw clamping component 3 is moved to dock the support claw on it with the front end of the shaft rod, the support claw will not be offset.

[0144] In this embodiment, it should be noted that the shaft rod anti-offset component 6 further includes: a sliding rail 63 horizontally arranged on the rack 1; and a sliding seat 64 slidingly arranged on the sliding rail 63.

[0145] Wherein, the bounce detection part 61 and the limiting part 62 are arranged on the sliding seat 64; the sliding direction of the sliding seat 64 is parallel to the axis of the shaft rod on the concentric shaft clamping component 2.

[0146] By slidingly arranging the bounce detection part 61, the bounce detection of the entire shaft rod is realized, avoiding unqualified products.

[0147] Embodiment eight:

[0148] The embodiment provides a welding method for processing a quartz claw, and specific steps of the welding method are as follows:

[0149] S1, arrange the shaft rod horizontally and clamp it by the concentric shaft clamping component 2; place the support claw on the support claw clamping component 3 and clamp it;

[0150] S2, control the rotation of the shaft, and then the shaft is detected by the bounce detection part 61, if the bounce value is qualified, it means that the shaft is qualified, and then the front end of the shaft is limited by the limiting part 62;

[0151] S3, control the upward movement of the support claw, and abut against the bottom of the front end of the shaft;

[0152] S4, control the rotation of the shaft again, and the shaft is detected by the bounce detection part 61 again, under the premise of ensuring that the shaft bounce value meets the requirements, the positions of the support claw and the limiting part 62 are fine-tuned until the support claw is accurately connected with the shaft;

[0153] S5, start the welding gun assembly 4, and the welding gun assembly 4 heats the welding surface between the support claw and the shaft to make them into an integrated structure;

[0154] S6, after cooling, the support claw is released by the support claw clamping assembly 3, then the shaft is rotated by a certain angle, then the next support claw is installed on the support claw clamping assembly 3, and the step S5 is returned until all the support claws on the shaft are welded, finally the welded quartz claw is taken off, and then the process is ended or returned to S1.

[0155] Through the above welding method, different types of quartz claws can be produced and processed, and the production efficiency is high, and the qualified rate of the produced products is also high.
