[0035] The present invention will be described in further detail below in conjunction with specific embodiments so that those skilled in the art can understand the present invention more clearly.

[0036] It should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integrated structures. Those skilled in the art will understand the specific meanings of such terms in this patent based on specific circumstances.

[0037] Example 1

[0038] This embodiment provides a RF power device wire fixing fixture, see Figure 1 , including a base 1 and a fixed material transfer fixture 2.

[0039] For details, see Figure 2-5The base 1 includes a bottom plate 101 , a spring 102 , and a buckle 103 .

[0040] The size of the base plate 101 is designed to be consistent with the size of the wire-welding area. The bottom surface of the base plate 101 is provided with mounting screw holes 110 for connecting the wire-welding system. The upper surface of the base plate 101 is provided with positioning grooves along its length.

[0041] The spring clip 102 can be an L-shaped structure, and is fixed to one end of the positioning slot by a bolt. The other end of the positioning slot defines a limiting opening 104, in which a rotating shaft 105 is fixed. A buckle 103 is sleeved on the rotating shaft 105. The buckle 103 has a positioning hole on the side facing the spring clip 102, and a spring 106 is disposed in the positioning hole. The end of the spring 106, which is away from the positioning hole, abuts against the inner wall of the limiting opening 104. The buckle 103 can rotate around the rotating shaft 105 within the limiting opening 104. The spring 106 is located below the rotating shaft 105 to support the buckle 103.

[0042] See also Figure 6-8 The fixed material transfer fixture 2 includes a mounting plate 201, a locking bolt 205, and two pressing plates 202. The mounting plate 201 is adapted to the positioning slot so that the mounting plate 201 can be placed in the positioning slot.

[0043] The mounting plate 201 is provided with five card slots 206 adapted to the RF power devices, and the five are arranged in a row along the length direction of the mounting plate 201. The mounting plate 201 is also provided with two rows of locking screw holes 203, and the two rows of locking screw holes 203 are respectively located on both sides of the card slots 206. The two pressing plates 202 correspond to the two rows of locking screw holes 203 respectively. The pressing plate 202 is provided with a strip hole 204, and the strip hole 204 is arranged along the width direction of the mounting plate 201. One end of the locking bolt 205 passes through the strip hole 204 and is screwed to the locking screw hole 203, thereby locking and fixing the pressing plate 202 and the mounting plate 201.

[0044] Based on the above structure, the use process of the RF power device bonding wire fixing fixture provided in this embodiment may include the following steps:

[0045] S1. Loosen the locking bolts 205 that fix the pressure plate 202 so that the pressure plate 202 can move back and forth along the width direction of the mounting plate 201 through the strip hole 204. Move the two pressure plates 202 to both sides to the open state. At this time, the product can be placed in the card slot 206 (five can be placed at a time). Then move the two pressure plates 202 to the middle to the closed state, tighten the locking bolts 205, and then fix the product in the card slot 206.

[0046] S2. After fixing the product, flip the buckle 103 outward to open it. At this time, the spring 106 is compressed, and the mounting plate 201 of the fixed material transfer fixture 2 is placed in the positioning groove of the base 1. Then release the buckle 103. Due to the elastic force of the spring 106, the buckle 103 rotates and resets, and presses the mounting plate 201. With the help of the spring piece 102, the fixed material transfer fixture 2 can be clamped and fixed on the base 1, and the wire welding process can be carried out.

[0047] S3. After the wire welding system completes the wire welding on the product, the buckle 103 is flipped outward to open and the fixed material transfer fixture 2 is moved out of the base 1.

[0048] S4. The material transfer fixture 2 to be fixed is placed to cool, the locking bolts 205 of the fixed pressing plate 202 are loosened, the two pressing plates 202 are moved to both sides to the open state, the product is taken out, and the wire welding process is completed.

[0049] S5. Repeat steps S1 to S4 to complete the wire bonding process of the RF power device product.

[0050] Since the welding wire system needs to heat the product (to facilitate welding), the staff cannot manually touch the fixture during the entire process of fixing the material transfer fixture 2 up and down.

[0051] To avoid burns from heating. In this embodiment, see Figure 2 , a buckle tool hole 109 is provided on the buckle 103. By inserting a tool (such as a screwdriver) into the buckle tool hole 109, the buckle 103 can be turned over, and the operation is simple and convenient.

[0052] See also Figure 7 , two clamping holes 208 are provided on the mounting plate 201. Insert a tool such as tweezers into the clamping holes 208 to move the mounting plate 201, which is simple and convenient to operate.

[0053] In order to improve the stability of the fixed material transfer fixture 2 on the base 1, in this embodiment, see Figure 2-3 Two vacuum holes 107 are provided on the bottom surface of the positioning groove, an external vacuum hole 108 is provided on the bottom surface of the bottom plate 101, and an air path hole is provided on the side wall of the bottom plate 101. The external vacuum hole 108, the vacuum hole 107, and the air path hole are connected, and the air path hole is blocked with a sealing pin.

[0054] After placing the mounting plate 201 in the positioning groove of the base plate 101, it is connected to the vacuum system through the external vacuum hole 108 to perform vacuum suction, so that the mounting plate 201 and the base plate 101 are tightly fitted and fixed, thereby improving the stability of the fixed material transfer fixture 2 on the base 1, and thereby improving the accuracy of the wire welding process.

[0055] In order to improve the stability of the RF power device in the card slot 206, in this embodiment, see Figure 8A spring piece 207 is provided between the pressing plate 202 and the mounting plate 201 , and the spring piece 207 is used to press and fix the RF power device.

[0056] Specifically, the spring 207 includes a curved pressure plate and a connecting plate that fits in place with the pressure plates 202. When the two pressure plates 202 are moved toward the center to a closed position, the curved pressure plate precisely presses the RF power device into the slot 206. When the two pressure plates 202 are moved toward the sides to an open position, the curved pressure plate separates from the RF power device.

[0057] The curved pressure plate and the connecting plate are an integrated structure, and the connecting plate is mounted on the pressure plate 202 by bolts.

[0058] Example 2

[0059] Based on Example 1, the base 1 is compatible with the COC wire fixing fixture.

[0060] Specifically, when compatible with COC wire, see Figure 9 , insert a tool (such as a screwdriver) into the buckle tool hole 109, and use force to flip the buckle 103 outward to open. Then insert tweezers into the fishbone clamp tool hole, clamp and transfer the fishbone clamp and place it on the base plate 101, and perform vacuum suction through the external vacuum hole 108 to make the fishbone clamp fit tightly with the base plate 101. Then release the force, and the buckle 103 rotates on the rotating shaft 105 under the action of the spring 106, so that the buckle 103 presses the fishbone clamp. In this way, the fishbone clamp is firmly and horizontally attached to the base plate 101, completing the horizontal fixation of the fishbone clamp, thereby reducing manufacturing costs.

[0061] In this way, the same wire bonding system can be compatible with completing the wire bonding of RF power devices and COC products.

[0062] The mechanisms, components and parts not specifically described in the present invention are all existing structures in the prior art and can be directly purchased from the market.

[0063] In the description of this utility model, it should be understood that the terms "upper," "lower," "left," "right," and the like indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, specific orientation structure, or operation. Therefore, they should not be construed as limiting this utility model. In the description of this utility model, unless otherwise specified, "plurality" means two or more.

[0064] The above is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
