Description

Technical Field

[0001] This utility model relates to the field of crystal boat box welding technology, specifically a welding fixture for ultrasonic equipment. Background Technology

[0002] In semiconductor manufacturing, photovoltaic industry, and the production of precision electronic components, crystal boats serve as crucial components for carrying, transporting, and storing semiconductor materials such as silicon wafers. Their structural strength and sealing performance play a decisive role in protecting these precision components from contamination and damage. Currently, ultrasonic welding technology has become the mainstream choice in crystal boat assembly processes due to its advantages such as high efficiency, environmental friendliness, and stable welding quality.

[0003] While existing technologies can weld crystal boat boxes, it is often inconvenient to fix the crystal boat boxes, which can lead to displacement during welding and compromise the quality. Furthermore, it is not convenient to adjust the height of the ultrasonic welding mechanism during welding, making it difficult to quickly weld crystal boat boxes of different diameters. This results in significant limitations in the use of the overall tooling, hindering its widespread adoption. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a welding fixture for ultrasonic equipment. It can effectively solve the problems in the prior art, which are often inconvenient to fix the crystal boat box, resulting in displacement during welding and inability to guarantee the quality. Furthermore, it is not convenient to adjust the height of the ultrasonic welding mechanism during welding, which makes it difficult to quickly weld crystal boat boxes of different diameters. As a result, the overall fixture has great limitations in use and is not convenient for widespread application.

[0005] The technical solution adopted by this utility model is: a welding fixture for an ultrasonic device, including a base, a fixing rod, and a crystal boat box body. A fixing buckle is provided on the outer wall of the fixing rod. An ultrasonic head is fixedly installed at the end of the fixing buckle away from the fixing rod. A welding head is provided at the end of the ultrasonic head away from the fixing rod. A side fixing plate, a support plate, and a support frame are provided on the base for fixing. A tray is fixedly installed on the side fixing plate near the crystal boat box body. A top plate is fixedly installed at the end of the support frame away from the base. A limiting groove is formed at the end of the top plate near the crystal boat box body, and the limiting groove abuts against the crystal boat box body.

[0006] Preferably, a side positioning hole is provided through the side fixing plate, and two identical side fixing plates, side positioning holes and support plates are provided, and the two side fixing plates, side positioning holes and support plates are symmetrically distributed about the center line of the machine base.

[0007] Through the above technical solution, two sets of symmetrically distributed side fixing plates and support plates can provide balanced clamping force from both sides of the crystal boat box body, avoiding box displacement caused by unilateral force during welding. The side positioning holes can be fixed to the machine base with bolts, and the position of the side fixing plates can be adjusted to adapt to crystal boat boxes of different specifications.

[0008] Preferably, the support plate has a through-hole for positioning and a slot for locking, and the crystal boat box body fits into the slot.

[0009] Through the above technical solution, the slot fits into the edge of the crystal boat box body to form a positioning reference, ensuring that the box body is in the preset position during welding. The support positioning hole can be fixed to the support plate and the machine base with bolts to prevent the support plate from shifting during welding vibration.

[0010] Preferably, an mounting plate is fixedly installed at one end of the support frame near the crystal boat box body, and the mounting plate is in contact with the crystal boat box body.

[0011] Through the above technical solution, the mounting plate contacts the top surface of the crystal boat box body, providing additional support. Especially when welding the top structure of the crystal boat box, it can reduce the deformation of the box body caused by high-frequency ultrasonic vibration.

[0012] Preferably, a fixing buckle 2 is provided at one end of the base near the fixing rod, and an adjusting bolt 2 is threaded through the outer edge of the fixing buckle 2, and the fixing rod is adapted to the fixing buckle 2.

[0013] Through the above technical solution, adjusting bolt two can loosen or tighten the clamping force of fixing buckle two on fixing rod, allowing the fixing rod to be finely adjusted in the vertical direction, which can be adapted to crystal boat boxes of different heights, or the distance between it and the box body can be adjusted according to the wear of the welding head.

[0014] Preferably, an adjusting bolt is threaded through the outer edge of the fixing buckle, and the fixing buckle is adapted to the fixing rod.

[0015] Through the above technical solution, adjusting bolt 1 can precisely adjust the position of fixing buckle 1 on fixing rod, thereby adjusting the rotation of ultrasonic head, which can be easily adapted to different parts of welding crystal boat box.

[0016] Preferably, the welding head is located directly above the crystal boat box body, and the support frame has a through mounting hole.

[0017] The above technical solution uses mounting holes to fix the support frame and the top plate. The height of the top plate can be adjusted by bolts to accommodate crystal boat boxes of different thicknesses. At the same time, it enhances the structural rigidity of the support frame, thereby affecting the positioning effect of the limiting groove.

[0018] Compared with the prior art, this utility model provides a welding fixture for ultrasonic equipment, which has the following beneficial effects:

[0019] 1. This welding fixture for ultrasonic equipment, through a side fixing plate, a support plate, and a support frame, can fix the crystal boat box at multiple angles. Furthermore, in conjunction with the upper side positioning holes, mounting holes, and support positioning holes, it enables rapid installation of the side fixing plate, support plate, and support frame. The installation positions of the side fixing plate, support plate, and support frame can be adjusted according to actual conditions, improving its versatility in use and preventing displacement during welding, thus avoiding any impact on quality.

[0020] 2. The welding fixture for this ultrasonic equipment has an adjusting bolt 2 that can loosen or tighten the clamping force of the fixing buckle 2 on the fixing rod, allowing the fixing rod to be finely adjusted in the vertical direction. It can be adapted to crystal boat boxes of different heights, or its distance from the box can be adjusted according to the wear of the welding head, thus improving its versatility in use.

A fixing buckle 3 is provided on the outer wall of the fixing rod 2. An ultrasonic head 5 is fixedly installed at the end of the fixing buckle 3 away from the fixing rod 2. A welding head 6 is provided at the end of the ultrasonic head 5 away from the fixing rod 2. The base 1 is provided with a side fixing plate 7, a support plate 10, and a support frame 13 for fixing.

A limiting groove 17 is formed at the end of the top plate 16 near the crystal boat body 18, and the limiting groove 17 abuts against the crystal boat body 18.

[0032] Specifically, a side positioning hole 8 is provided through the side fixing plate 7. There are two identical side fixing plates 7, side positioning holes 8 and support plates 10. The two side fixing plates 7, side positioning holes 8 and support plates 10 are symmetrically distributed about the center line of the base 1. The advantage is that the two sets of symmetrically distributed side fixing plates 7 and support plates 10 can provide balanced clamping force from both sides of the crystal boat box body 18, avoiding box displacement caused by unilateral force during welding. The side positioning hole 8 can be fixed to the base 1 with bolts, and the position of the side fixing plate 7 can be adjusted to adapt to crystal boat boxes of different specifications.

[0033] Specifically, a support positioning hole 11 is provided through the support plate 10, and a slot 12 is provided on the support plate 10. The crystal boat box body 18 fits into the slot 12. The advantage is that the slot 12 fits into the edge of the crystal boat box body 18 to form a positioning reference, ensuring that the box body is in the preset position during welding. The support positioning hole 11 can fix the support plate 10 and the machine base 1 with bolts to prevent the support plate 10 from shifting during welding vibration.

[0034] Specifically, a mounting plate 15 is fixedly installed at one end of the support frame 13 near the crystal boat box body 18. The mounting plate 15 is in contact with the crystal boat box body 18. The advantage is that the mounting plate 15 is in contact with the top surface of the crystal boat box body 18, providing additional support force. Especially when welding the top structure of the crystal boat box, it can reduce the deformation of the box body caused by ultrasonic high-frequency vibration.

[0035] Example 2: Figure 2-8 As shown, this is an improvement on the previous embodiment.

[0036] Specifically, a fixing buckle 29 is provided at one end of the base 1 near the fixing rod 2. An adjusting bolt 20 is threaded through the outer edge of the fixing buckle 29. The fixing rod 2 is adapted to the fixing buckle 29. The advantage is that the adjusting bolt 20 can loosen or tighten the clamping force of the fixing buckle 29 on the fixing rod 2, allowing the fixing rod 2 to be finely adjusted in the vertical direction. It can be adapted to crystal boat boxes of different heights, or the distance between the welding head 6 and the box body can be adjusted according to the wear condition of the welding head 6.

[0037] Specifically, an adjusting bolt 4 is threaded through the outer edge of the fixing buckle 3. The fixing buckle 3 is compatible with the fixing rod 2.

[0038] Specifically, the welding head 6 is located directly above the crystal boat box body 18, and the support frame 13 has a through mounting hole 14. The advantage is that the mounting hole 14 is used to fix the support frame 13 and the top plate 16, which can be adapted to crystal boat boxes of different thicknesses, while enhancing the structural rigidity of the support frame 13, thereby affecting the positioning effect of the limiting groove 17.

[0039] Working principle: During use, two sets of symmetrically distributed side fixing plates 7 and support plates 10 provide balanced clamping force from both sides of the crystal boat box body 18, preventing box displacement caused by unilateral force during welding. The side positioning holes 8 can be fixed to the machine base 1 with bolts. The position of the side fixing plates 7 can be adjusted to adapt to crystal boat boxes of different specifications. The slots 12 fit against the edge of the crystal boat box body 18 to form a positioning reference, ensuring that the box is in the preset position during welding. The support positioning holes 11 can be fixed to the support plate 10 and the machine base 1 with bolts to prevent the support plate 10 from shifting during welding vibration. The mounting plate 15 contacts the top surface of the crystal boat box body 18, providing additional support force, especially when welding crystal boats. When the top structure of the box is designed, the deformation of the box body caused by the high-frequency vibration of the ultrasonic waves can be reduced. The adjusting bolt 20 can loosen or tighten the clamping force of the fixing buckle 19 on the fixing rod 2, allowing the fixing rod 2 to be finely adjusted in the vertical direction. It can be adapted to crystal boat boxes of different heights, or the distance between the welding head 6 and the box body can be adjusted according to the wear of the welding head 6. The adjusting bolt 4 can precisely adjust the position of the fixing buckle 3 on the fixing rod 2, thereby adjusting the rotation of the ultrasonic head 5. It can be easily adapted to different parts of the welding crystal boat box. The mounting hole 14 is used to fix the support frame 13 and the top plate 16, which can be adapted to crystal boat boxes of different thicknesses, while enhancing the structural rigidity of the support frame 13, thereby affecting the positioning effect of the limiting groove 17.
