Description

Technical Field

[0001] This utility model relates to the field of welding processing technology, and in particular to a rod cap auxiliary clamping welding device. Background Technology

[0002] In the process of cleaning silicon wafers, baskets are generally used as containers to hold the wafers. To prevent the wafers from floating and shifting during cleaning, pressure bars with several teeth are usually installed on the baskets to limit the wafers and keep them stable in the liquid. The pressure bars are connected to the grooves on the baskets by the caps at both ends to form a locking assembly structure, which ensures a firm connection between the pressure bars and the baskets, prevents accidental detachment, and enhances the stability of the gripping.

[0003] In related technologies, welding is commonly used to connect the pressure rod and the rod cap. Although this method can connect the pressure rod and the rod cap into a whole, it requires two people to work together to complete the welding process. One person holds the pressure rod and the rod cap and rotates them steadily for one revolution, while the other person controls the welding torch to move to the joint of the pressure rod and the rod cap and perform the welding operation. The welding efficiency is low, and this operation also places high demands on the skills and experience of the operators. The rod or the rod cap is prone to deviating from the welding position, resulting in poor weld formation and problems such as uneven and discontinuous welds. This can easily cause the pressure rod to fall off during the cleaning process, thus losing its restraining function on the silicon wafer. In addition, liquid can easily accumulate at the joint between the rod cap and the silicon wafer, affecting the cleaning effect of the silicon wafer.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background technology of this utility model, and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0032] like Figures 1 to 8 The rod cap auxiliary clamping welding device shown includes: a support assembly 10 and a welding assembly 20 and a clamping assembly 30 disposed on the top of the support assembly 10;

[0033] The support assembly 10 is used to support the pressure rod 1 and the cap body; the welding assembly 20 is disposed on the support assembly 10 and is used to weld the connection between the pressure rod 1 and the cap 2; the clamping assembly 30 is disposed at both ends of the pressure rod 1 along the axial direction of the pressure rod 1 and is used to clamp and fix the pressure rod 1 and the cap 2.

[0034] The welding assembly 20 includes a welding torch 21, and the clamping assembly 30 includes a motor 31, a first sleeve 32, a second sleeve 33, and a clamping seat 34. The motor 31 and the clamping seat 34 are arranged opposite to each other and are located at both ends of the pressure rod 1. The first sleeve 32 is fixedly arranged at the output end of the motor 31 and connected to one end of the pressure rod 1. The second sleeve 33 is arranged on the clamping seat 34, and the rod cap 2 is arranged in the second sleeve 33. The welding torch 21 is inclinedly arranged on one side of the outer shaft surface of the pressure rod 1, and the welding head of the welding torch 21 is arranged opposite to the connection between the pressure rod 1 and the rod cap 2.

[0035] This invention uses a clamping assembly 30 to fix the pressure rod 1 and the rod cap 2, ensuring their stable position during welding. This avoids poor weld formation caused by hand shaking or movement of the welding equipment, resulting in uniform welds with consistent width, thus improving the stability of welding quality. It also eliminates the need for manual hand-held rotation of the pressure rod 1 and the rod cap 2 during welding, reducing manual operation steps and time, and significantly improving welding efficiency.

[0036] Specifically, the welding process using the rod cap 2 as an auxiliary clamping welding device is as follows: Place the pressure rod 1 on the support assembly 10, with one end connected to the first sleeve 32 and the other end close to the second sleeve 33; place the rod cap 2 in the second sleeve 33, ensuring that the rod cap 2 is stably fitted onto the pressure rod 1, and the clamping seat 34 fixes the rod cap 2; start the motor 31, which drives the first sleeve 32 to rotate, causing the pressure rod 1 and the rod cap 2 to rotate synchronously, and the welding gun 21 starts working to weld the connection between the pressure rod 1 and the rod cap 2; after the pressure rod 1 rotates one revolution, the welding gun 21 completes the welding of the connection between the pressure rod 1 and the rod cap 2. After welding is completed, turn off the motor 31 and the welding gun 21, remove the welded pressure rod 1 and the rod cap 2, and perform subsequent inspection and processing.

[0037] Based on the above embodiments, the support assembly 10 includes a table frame 11 and a base plate 12. The table frame 11 is set on the ground, and the base plate 12 is fixedly set on the top of the table frame 11. The pressure rod 1 and the cap are located on the top surface of the base plate 12. The table frame 11 provides a stable support structure for the entire welding device, ensuring that the device will not shake or tilt during operation, and ensuring the smooth progress of the welding operation. The base plate 12 provides a bearing platform for the pressure rod 1 and the cap. The top surface of the base plate 12 is flat, which facilitates the placement and positioning of the pressure rod 1 and the cap, ensuring that they remain stable during the welding process and facilitating the accurate operation of the welding assembly 20 and the clamping assembly 30.

[0038] Based on the above embodiments, a controller 13 is provided on one side of the table frame 11. The controller 13 is equipped with a start / stop button and a speed adjustment knob. The start / stop button is used to control the power supply to the welding assembly 20 and the clamping assembly 30, and the speed adjustment knob is used to control the speed of the motor 31. The controller 13 centrally controls the operating status of the welding assembly 20 and the clamping assembly 30. The operator can conveniently control and adjust the welding process in real time through the controller 13, which improves the convenience and flexibility of operation. The operator can start or stop the welding process by pressing the start / stop button to ensure the timeliness and safety of the welding operation and avoid welding quality problems or safety accidents caused by unexpected operation or stoppage of the equipment. The operator can also adjust the speed of the motor 31 by adjusting the speed adjustment knob according to the welding requirements and the characteristics of the pressure rod 1, thereby adjusting the rotation speed of the pressure rod 1 to match the welding speed with the welding quality, which improves the adaptability and controllability of the welding.
