Description

Technical Field

[0001] This utility model relates to the field of quartz rod processing technology, specifically a quartz rod welding positioning device. Background Technology

[0002] With the rapid development of industries such as semiconductors, optical instruments, and photovoltaics, quartz rods are widely used in the manufacture of key components such as quartz boats, optical prisms, and semiconductor substrate supports due to their high temperature resistance, good light transmittance, and strong chemical stability. The welding and processing precision of quartz rods directly affects the performance of end products.

[0003] During the processing of quartz rods, clamping them in only one direction can easily cause displacement of the quartz rod during welding, and it is difficult to achieve rotary welding of the quartz rod. The weld joint is prone to local overmelting or incomplete welding, affecting uniformity. At the same time, when using traditional equipment to inspect the welding quality, the workpiece must be disassembled before a full inspection can be carried out, which is cumbersome and inefficient. Utility Model Content

[0004] The purpose of this utility model is to provide a quartz rod welding positioning device to solve the technical problems of over-melting or incomplete welding caused by unstable clamping during the quartz rod processing and welding process, as well as the complicated clamping and disassembly process and low efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A quartz rod welding positioning device includes a mounting plate and an L-shaped support frame fixed to the top of the mounting plate. A fixing plate is fixedly connected to the top edge of the support frame, and a welding component is embedded in the top of the support frame.

[0007] Vertical plates are installed on both sides of the top of the mounting plate. A positioning cylinder extending to the inner end of the fixed plate is embedded through the upper end of each vertical plate. Two rotating rollers are rotatably connected to the inner cylinder of the positioning cylinder. A through hole is opened through the top of each rotating roller near the inner end of the fixed plate. A first reciprocating cylinder is embedded in the upper end of each vertical plate. A drive plate is fixedly connected to the output end of each first reciprocating cylinder. A turntable is rotatably connected to the lower end of one side of the drive plate.

[0008] The outer wall of the fixed plate is equipped with a fixed block, and the bottom of the fixed block is fixedly connected to a second reciprocating cylinder. The output end of the second reciprocating cylinder is fixedly connected to a lifting frame. The inner end of the lifting frame is equipped with a servo motor. The output end of the servo motor is fixedly connected to a drive shaft. One end of the drive shaft is fixedly connected to a rubber roller. The drive shaft rod wall is rotatably connected to an I-shaped slider through a bearing.

[0009] As a preferred embodiment of this utility model, a top notch is provided on the upper end of the side of the positioning cylinder away from the fixing plate.

[0010] As a preferred embodiment of this utility model, both positioning cylinders are made in a hollow shape.

[0011] As a preferred embodiment of this utility model, the turntable surface is fixedly connected with a number of rubber protrusions distributed in a circular array.

[0012] As a preferred embodiment of this utility model, both fixed plates have through grooves on their side walls, and the diameter of the slider is matched with the diameter of the groove.

[0013] Compared with the prior art, the beneficial effects of this utility model of a quartz rod welding positioning device are as follows: the second reciprocating cylinder drives the rubber roller to press down, forming a "three-dimensional fixation" with the rotating roller and turntable; the servo motor drives the rubber roller to rotate, driving the quartz rod to rotate synchronously, and the slider guides smoothly along the slide groove to ensure that the axis of the quartz rod does not deviate during the rotation, so that the welding components can perform circumferential uniform welding at the joint, avoiding local overmelting or incomplete welding; after welding, the quartz rod can be rotated by driving the servo motor at one end alone, and the appearance and fit of the weld can be fully inspected through the top notch, eliminating the step of disassembling the workpiece required for traditional inspection, improving operation efficiency and inspection convenience.

[0023] See Figure 1-4 This utility model provides a quartz rod welding positioning device, which includes a mounting plate 1 and an L-shaped support frame 2 fixed to the top of the mounting plate 1. A fixing plate 22 is fixedly connected to the top edge of the support frame 2, and a welding component 21 is embedded in the top of the support frame 2.

[0024] The welding assembly 21 includes a laser emitter, an angle and height adjustment mechanism, and a control and cooling assembly (which are common knowledge and will not be described in detail).

[0025] When using the device, first fix the mounting plate 1 of the device stably on the welding workbench, and ensure that the L-shaped support frame 2 is positioned directly opposite the welding operation area. Then, start the welding component 21 embedded at the top of the support frame 2 to perform welding operations on the joint of the two quartz rods.

[0026] Vertical plates 11 are installed on both sides of the top of the mounting plate 1. Positioning cylinders 12 extending to the inner end of the fixed plate 22 are embedded through the upper end of the vertical plates 11. Two rotating rollers 13 are rotatably connected to the ground inside the positioning cylinders 12. The top of the rotating rollers 13 near the inner end of the fixed plate 22 is provided with a through hole 101. A first reciprocating cylinder 14 is embedded in the upper end of the vertical plates 11. A drive plate 15 is fixedly connected to the output end of the first reciprocating cylinder 14. A turntable 16 is rotatably connected to the lower end of one side of the drive plate 15. A top notch 102 is provided on the upper end of the side of the positioning cylinder 12 away from the fixed plate 22. Both positioning cylinders 12 are hollow. Several rubber convex strips 17 distributed in a circular array are fixedly connected to the surface of the turntable 16.

[0027] Fixing blocks 23 are installed on the outer walls of the fixing plates 22. The bottom of each fixing block 23 is fixedly connected to a second reciprocating cylinder 24. The output end of each second reciprocating cylinder 24 is fixedly connected to a lifting frame 25. The inner end of each lifting frame 25 is equipped with a servo motor 26. The output end of each servo motor 26 is fixedly connected to a drive shaft. One end of each drive shaft is fixedly connected to a rubber roller 28. The drive shaft rod wall is rotatably connected to an I-shaped slider 27 through a bearing. The side walls of both fixing plates 22 are provided with through grooves 201, and the diameter of each slider 27 matches the diameter of the groove 201.

[0028] The first reciprocating cylinder 14 and the second reciprocating cylinder 24 are driven to operate synchronously by an externally installed synchronization controller to avoid uncoordinated operation.

[0029] It provides an observation window for operators to view the insertion depth, position, and docking status of the quartz rod in the positioning cylinder 12 in real time, and avoids the quartz rod being inserted too deeply or misaligned due to obstruction of the field of vision.

[0030] The positioning cylinders 12 are all hollow, providing a through-type receiving and guiding channel for the quartz rod, ensuring that the quartz rod can be stably inserted along the axis of the positioning cylinder 12.

[0031] The rubber protrusion 17 is elastic and can prevent scratching the surface of the quartz rod during clamping; the protrusion structure can increase the friction with the quartz rod and improve the clamping stability.

[0032] Provide a stable sliding track for slider 27 to ensure that slider 27 drives the drive shaft and rubber roller 28 to move smoothly along the slide groove 201 when rotating or adjusting the position of the quartz rod.

[0033] In use, the two quartz rods to be welded are inserted from the ends of the positioning cylinders 12 on both sides of the device away from the fixing plate 22, so that the quartz rods are inserted through the hollow channel of the positioning cylinder 12 and the bottom end rests on the rotating roller 13 inside the positioning cylinder 12. The operator can observe the insertion depth and position of the quartz rods through the top notch 102 at the top of the positioning cylinder 12 until the ends of the two quartz rods pass through the through hole 101 and are initially joined together inside the fixing plate 22.

[0034] Next, the first reciprocating cylinders 14 on both sides are started. Their output ends push the drive plate 15 to move towards the positioning cylinder 12, causing the turntable 16 to be embedded in the top notch 102 until the rubber protrusions 17 on the surface of the turntable 16 are in close contact with the surface of the quartz rod. The friction of the rubber protrusions 17 clamps the two quartz rods together, ensuring that the welding surfaces are tightly fitted and avoiding rigid contact that could scratch the quartz rods.

[0035] After confirming accurate positioning, the welding assembly 21 at the top of the support frame 2 is started to begin welding; at the same time, the second reciprocating cylinder 24 is started (the second reciprocating cylinder 24 is driven synchronously by the set synchronous controller), and its output end pushes the lifting frame 25 to move down, driving the servo motor 26, the transmission shaft and the rubber roller 28 to descend synchronously. Through the setting of the through hole 101, the rubber roller 28 can be made to make close contact with the top of the quartz rod, forming a three-dimensional fixed structure of "rotating roller 13 supporting the bottom + turntable 16 side abutting + rubber roller 28 pressing the top".

[0036] The servo motor 26 is started, and its output drives the transmission shaft and rubber roller 28 to rotate. The rubber roller 28 drives the quartz rod to rotate through friction. The rotating roller 13 rotates synchronously with the quartz rod to assist in guidance, ensuring that the axis does not deviate during the rotation of the quartz rod, realizing welding while rotating, and ensuring that the weld is uniform and flat.

[0037] After welding is completed, the welding assembly 21 is turned off, and the servo motor 26 is kept running or one of the servo motors 26 is driven separately to drive the welded quartz rod to rotate slowly. The operator can check the appearance, fit and flatness of the weld through the top notch 102 or other observation positions to determine whether the welding quality meets the standards.

[0038] The foregoing has shown and described the basic principles of the present invention. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Any modifications, equivalent substitutions, and improvements made within the scope of the present invention without departing from the scope of the present invention should be included within the protection scope of the present invention.
