Description

Technical Field

[0001] This utility model relates to the field of semiconductor processing technology, specifically to a quick-release and adjustment structure for a eutectic machine positioning pressure bar. Background Technology

[0002] Eutectic bonding machines, commonly used in semiconductor processing, eutectic bond the die to the socket. To ensure product quality, the stability and positional accuracy of the socket during clamping are crucial, necessitating axial and radial positioning and clamping. For example, the socket clamping and positioning eutectic bonding device for a eutectic bonding machine disclosed in patent CN217788342U includes an axial positioning mechanism with an axial positioning drive component and an axial positioning block. The axial positioning mechanism also features an axial positioning slider slidably mounted on the second mounting surface of a radial positioning sliding plate. The axial positioning block is mounted on the axial positioning sliding plate, and the axial positioning drive component is mounted on the radial positioning sliding plate and connected to the axial positioning slider, allowing the axial positioning drive component to drive the axial positioning slider to slide, thereby moving the axial positioning block. This axial positioning block serves as the positioning pressure bar of the eutectic bonding machine, acting as a structure to axially clamp the socket. Therefore, improving the installation stability and positional accuracy of the positioning pressure bar is key to ensuring product quality. While the aforementioned structure meets the axial clamping requirements of the tube seat, the surface of the axial positioning slider used to mount the axial positioning block is smooth, and it is fixed in place by relying solely on two elongated holes. Furthermore, due to assembly clearances and errors, there is a positional misalignment issue when the axial positioning block is installed on the axial positioning slider. Even with measurements using standard tools during installation, there is a risk of movement when tightening the screws. This leads to errors in the stability and positional accuracy of the axial positioning block, which are difficult to detect and negatively impact product quality. Summary of the Invention

[0003] To address the aforementioned problems in existing technologies, this invention aims to provide a quick-release and adjustable structure for a eutectic machine positioning rod. An adapter block is mounted on an axial sliding block, and two vertically spaced grooves are provided on the adapter block along the vertical direction. Simultaneously, protrusions are provided on both sides of the positioning rod. When the positioning rod is installed on the adapter block, the two protrusions can be vertically engaged into the two vertical grooves, and a portion of the adapter block can also be engaged into the gap between the two protrusions. This creates at least three limiting points between the clamping block and the positioning rod, resulting in higher accuracy in the installation position of the positioning rod and greater stability after installation, thus ensuring product quality. Furthermore, the adapter block has several vertically spaced fixing holes, and the positioning rod has several corresponding adjustment holes. These adjustment holes are strip-shaped holes arranged vertically, allowing for fine-tuning of the positioning rod on the adapter block along the vertical direction, making the structure more flexible.

[0004] The specific technical solution is as follows:

[0005] A quick-release and adjustable structure for a eutectic machine positioning rod includes an axial positioning mechanism slidably mounted on the eutectic stage. The axial positioning mechanism includes an axial sliding block and a positioning rod, with one end of the positioning rod mounted on the axial sliding block. The axial sliding block is poweredly connected to an axial movement driver. The structure further includes a transition block, the lower end of which is mounted on the axial sliding block, and the upper end of which extends vertically upwards. The positioning rod is detachably mounted on the upper end of the transition block. Two vertically spaced vertical sliding joints are provided on one side of the upper end of the transition block. The positioning rod has two protruding and spaced ridges on one side of its lower end, forming a cavity between them. The two ridges are respectively embedded into the two vertical sliding grooves. The upper end of the adapter block, located between the two vertical sliding grooves, can be embedded into the cavity in the opposite direction. Furthermore, the upper end of the adapter block has several fixing holes arranged at intervals in the vertical direction. The lower end of the positioning rod has several adjusting holes arranged at intervals in the vertical direction. The adjusting holes and fixing holes correspond one-to-one, and each adjusting hole is a strip-shaped hole arranged in the vertical direction.

[0006] In the aforementioned quick-release and adjustment structure for a eutectic machine positioning pressure bar, a vertical groove on the adapter block is a through groove extending through the thickness direction of the upper end of the adapter block.

[0007] The above-mentioned quick-release and adjustment structure for the positioning pressure bar of the eutectic machine includes guide slopes on both sides of the upper end of the adapter block. One end of each guide slope is connected to a vertical slide groove, and the two guide slopes correspond to two protruding strips.

[0008] The above-mentioned quick-release and adjustment structure for the positioning pressure bar of a eutectic machine includes a transition block comprising a base, a mounting base, and a reinforcing block. The base is horizontally mounted on the axial sliding block, the mounting base is arranged vertically, one side of the bottom of the mounting base is connected to one side of the base, and the reinforcing block is disposed between the base and the mounting base.

[0009] In the above-mentioned quick-release and adjustment structure for the positioning pressure bar of the eutectic machine, the height of the reinforcing block is lower than the height of the mounting base in the vertical direction, and the reinforcing block is located on one side of the mounting base.

[0010] The above-mentioned quick-release and adjustment structure for the positioning pressure bar of a eutectic machine includes two vertical slides respectively located on both sides of the mounting base, and one vertical slide passing through the connection between the reinforcing block and the mounting base in the vertical direction.

[0011] The above-mentioned quick-release and adjustment structure for the positioning pressure bar of a eutectic machine includes an adjustment scale on the side wall of the vertical slide groove on the reinforcing block and near the corresponding side, and the adjustment scale is arranged in the vertical direction.

[0012] The aforementioned quick-release and adjustment structure for a eutectic machine positioning rod further includes a pre-adjustment structure. The pre-adjustment structure includes a telescopic spring. In this case, the telescopic spring is placed at the bottom of the positioning rod, and the lower end of the telescopic spring abuts against the axial sliding block or mounting base.

[0013] The positive effects of the above technical solution are:

[0014] The aforementioned quick-release and adjustment structure for the eutectic machine positioning rod utilizes a transition block mounted on an axial sliding block. Two vertically spaced grooves are arranged on the transition block along the vertical direction. Simultaneously, protrusions corresponding to the two vertical grooves are embedded on both sides of the positioning rod. The portion of the transition block located between the two vertical grooves engages with the gap formed between the two protrusions, allowing the positioning rod to connect with the transition block through at least three limiting points. This ensures more accurate positioning and greater stability after installation, guaranteeing product processing quality. Furthermore, the transition block has several vertically spaced fixing holes, and the positioning rod has several corresponding, strip-shaped adjustment holes. These adjustment holes provide adjustment margins and accommodate fine-tuning of the positioning rod on the transition block, resulting in greater structural flexibility. Attached Figure Description

[0020] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 4 The technical solution provided by this utility model is described in detail, but the following content is not intended to limit this utility model.

[0021] Figure 1 This is a structural diagram of an embodiment of a quick-release and adjustment structure for a eutectic machine positioning pressure bar according to this utility model. Figure 1 As shown, the quick-release and adjustment structure for the eutectic bonding machine positioning rod provided in this embodiment includes an axial positioning mechanism. This mechanism axially positions and presses the tube socket, ensuring product quality for subsequent eutectic bonding of the chip. The axial positioning mechanism is slidably mounted on the eutectic stage, achieving stable installation. Furthermore, the axial positioning mechanism includes an axial sliding block 1 and a positioning rod 2. One end of the positioning rod 2 is mounted on the axial sliding block 1. The axial sliding block 1 is also connected to an axial movement driver, allowing the driver to move the block, thus enabling the positioning rod 2 to follow the block. Since the axial sliding block 1 moves along the axial direction of the tube socket, the positioning rod 2 also moves along the axial direction of the tube socket, allowing it to press against the tube socket from the end, achieving accurate positioning and maintaining stability during eutectic bonding.

[0022] Figure 2 This is a structural view of the adapter block according to a preferred embodiment of the present invention. Figure 3 This is a structural diagram of the adapter block from another perspective, representing a preferred embodiment of the present invention. (See diagram below.) Figures 1 to 3As shown, the axial positioning mechanism includes not only the axial sliding block 1 and the positioning pressure rod 2 mentioned above, but also a transition block 3. In this case, the lower end of the transition block 3 is mounted on the axial sliding block 1, and the upper end of the transition block 3 extends vertically upwards, allowing the transition block 3 to move axially along the pipe seat along with the axial sliding block 1. Simultaneously, the upper end of the transition block 3 can subsequently adapt to the vertical adjustment of the positioning pressure rod 2, resulting in a more rational structural design. At this point, the positioning rod 2 is disassembled and installed on the upper end of the adapter block 3. Two vertically spaced grooves 321 are formed on one side of the upper end of the adapter block 3. Simultaneously, two protruding and spaced ridges 21 are provided on one side of the lower end of the positioning rod 2, forming a cavity 22 between them. When the positioning rod 2 is installed on the upper end of the adapter block 3, the two ridges 21 on the positioning rod 2 can be respectively embedded into the two vertical grooves 321 of the adapter block 3, achieving mutual positioning between at least two parts of the positioning rod 2 and the adapter block 3. At the same time, the upper part of the adapter block 3 located between the two vertical grooves 321 can be embedded into the cavity 22 in the opposite direction, thus adding another mutual positioning structure. This increases the number of positioning structures between the positioning rod 2 and the adapter block 3, ensuring improved accuracy of the installation position when the positioning rod 2 is installed on the adapter block 3 and meeting the requirements for quick assembly and disassembly. In addition, the positioning rod 2 and the adapter block 3 are directly positioned and limited by the vertical slide groove 321, the protrusion 21 and the cavity 22, which eliminates the risk of movement caused by assembly errors when tightening screws, ensuring the stability and positional accuracy of the positioning rod 2, thereby guaranteeing the quality of the product.

[0023] Furthermore, several fixing holes 322 are provided at the upper end of the adapter block 3, and these fixing holes 322 are arranged at intervals in the vertical direction, providing conditions for the installation of the positioning rod 2. At the same time, several adjusting holes 23 are provided at the lower end of the positioning rod 2, and these adjusting holes 23 are arranged at intervals in the vertical direction. When the positioning rod 2 is installed on the adapter block 3, the adjusting holes 23 and the fixing holes 322 correspond one-to-one and are connected and locked by screws or other structures. Each adjusting hole 23 is a strip-shaped hole arranged in the vertical direction, so that the adjusting hole 23 has clearance space in the vertical direction. This can meet the installation requirements of the positioning rod on the adapter block 3 and adapt to the adjustment requirements of the positioning rod 2 in the vertical direction. Moreover, when adjusting in the vertical direction, the movement of the protrusion 21 in the vertical slide groove 321 and the sliding of the part of the adapter block 3 located between the two vertical slide grooves 321 in the cavity 22 can be used for guidance, making the adjustment process more stable, the adjustment efficiency higher, and the adjustment more convenient.

[0024] Specifically, the vertical groove 321 on the adapter block 3 is a through groove that runs through the thickness direction of the upper end of the adapter block 3. This results in the vertical groove 321 lacking one side wall and bottom. That is, the side wall of the adapter block 3 corresponding to the vertical groove 321 constitutes the only side wall of the vertical groove 321. This allows the protrusion 21 of the positioning rod 2 to be embedded into the vertical groove 321, thereby achieving positioning by having one side of the protrusion 21 fit against the only side wall of the vertical groove 321, improving the accuracy of the installation position and ensuring product processing quality. It also reduces the space occupied by the adapter block 3 on one side of the positioning rod 2, providing installation space for the radial positioning mechanism of the subsequent pipe seat arrangement.

[0025] More specifically, guide ramps 323 are provided on both sides of the upper end of the adapter block 3. One end of each guide ramp 323 is connected to one of the two vertical slide grooves 321, so that each guide ramp 323 can serve as an extension structure of the two vertical slide grooves 321. Furthermore, each guide ramp 323 corresponds to one of the two protrusions 21, so that when the positioning pressure rod 2 is installed on the adapter block 3, the guide ramps 323 can guide the protrusions 21 to be embedded into the vertical slide grooves 321, which facilitates quick alignment and embedding, making disassembly and assembly more convenient and efficient.

[0026] More specifically, the adapter block 3 includes a base 31, a mounting base 32, and a reinforcing block 33. The base 31 is horizontally mounted on the axial sliding block 1. The base 31 has a planar structure, which provides a large contact area between the base 31 and the axial sliding block 1, improving the stability of the adapter block 3 mounted on the axial sliding block 1. The mounting base 32 is arranged vertically, better accommodating the installation and adjustment requirements of the positioning rod 2. Simultaneously, one side of the bottom of the mounting base 32 is connected to one side of the base 31, allowing the mounting base 32 to be stably mounted on the axial sliding block 1 via the base 31. Furthermore, the reinforcing block 33 is positioned between the base 31 and the mounting base 32, with one lower end of the reinforcing block 33 connected to the base 31 and one upper side connected to the mounting base 32. This reinforces the connection between the base 31 and the mounting base 32, improving the stability and reliability of the mounting base 32 mounted on the base 31, ensuring that the positioning rod 2 mounted on the mounting base 32 is more stable and reliable during use.

[0027] More specifically, in the vertical direction, the height of the reinforcing block 33 is lower than the height of the mounting base 32, and the reinforcing block 33 is set on one side of the mounting base 32. This ensures that the reinforcing block 33 strengthens the mounting base 32, while reducing the impact of the reinforcing block 33 on the upper structure of the mounting base 32, and facilitates the installation and removal of the positioning pressure rod 2 on the upper part of the mounting base 32.

[0028] More specifically, two vertical grooves 321 are respectively provided on both sides of the mounting base 32, which facilitates the cooperation with the protrusion 21 of the positioning pressure rod 2 to realize the installation of the positioning pressure rod 2 on the mounting base 32. In addition, one vertical groove 321 passes through the connection between the reinforcing block 33 and the mounting base 32 in the vertical direction, which not only ensures the connection between the reinforcing block 33 and the mounting base 32 and improves the stability of the mounting base 32, but also forms a groove structure at the connection between the mounting base 32 and the reinforcing block 33 through the vertical groove 321, which is adapted to the embedding of the protrusion 21 on the positioning pressure rod 2, avoiding the obstruction of the protrusion 21 when it moves up and down with the positioning pressure rod 2, and meeting the needs of adjusting the positioning pressure rod 2.

[0029] Figure 4 This is a structural diagram showing the positioning pressure rod installed on the adapter block in a preferred embodiment of this utility model. Figure 4 As shown, an adjustment scale 331 is provided on the side wall of the vertical slide 321 on the reinforcing block 33, near the corresponding side. This allows the adjustment scale 331 to be located beside the vertical slide 321, facilitating subsequent use with the positioning rod 2. Furthermore, placing the adjustment scale 331 on the reinforcing block 33 does not affect the structure of the mounting base 32, ensuring the structural strength and stability of the mounting base 32. Preferably, the adjustment scale 331 is achieved through laser engraving, facilitating its processing on the reinforcing block 33. Moreover, the adjustment scale 331 is arranged vertically, so that when the positioning rod 2 is adjusted vertically, the change in the bottom surface of the positioning rod 2 relative to the adjustment scale 331 is directly and objectively reflected, facilitating quick adjustment by the operator.

[0030] More specifically, the positioning rod 2 is also provided with a pre-adjustment structure 4, which in turn includes a telescopic spring. During assembly, the telescopic spring is placed at the bottom of the positioning rod 2. Preferably, a telescopic hole is opened vertically on the bottom surface of the positioning rod 2, and the upper end of the telescopic spring is inserted into the telescopic hole. The telescopic hole provides conditions for the stable installation of the telescopic spring and prevents displacement problems during use. Meanwhile, the lower end of the telescopic spring extends outside the telescopic hole and abuts against the axial sliding block 1 or the mounting base 32. That is, the telescopic spring provides a small amount of elastic support force for the positioning rod 2. When it is necessary to adjust the position of the positioning rod 2 in the vertical direction, the telescopic spring can prevent the positioning rod 2 from falling rapidly when the screw used for locking in the adjustment hole 23 is loosened slightly. This prevents the lower end of the electric positioning rod 2 from directly and rapidly impacting the axial sliding block 1 or the mounting base 32, which would cause slight deformation of the positioning rod 2 and affect the positioning accuracy. Furthermore, the positioning rod 2 can move upward on its own under the action of the telescopic spring, and the height position of the positioning rod 2 can be adjusted by the operator slightly pressing down on the positioning rod 2, making the operation more convenient.

[0031] The quick-release and adjustment structure for the eutectic machine positioning rod provided in this embodiment includes an axial sliding block 1, a positioning rod 2, and a transition block 3. The positioning rod 2 is installed by setting the transition block 3 on the axial sliding block 1. The transition block 3 has two vertically spaced grooves 321 along the vertical direction, and protruding strips 21 corresponding to the two vertical grooves 321 are provided on both sides of the positioning rod 2, realizing the embedding of the protruding strips 21 and the vertical grooves 321. Furthermore, the part of the transition block 3 located between the two vertical grooves 321 can be embedded into the two protruding strips 21. Within the concave cavity 22 formed between the positioning rod 2 and the adapter block 3, positioning is achieved not only through the cooperation of the vertical sliding grooves 321 and the protrusions 21 on both sides, but also through the cooperation of the portion between the vertical sliding grooves 321 and the concave cavity 22. This provides more positioning points, thereby ensuring the accuracy of the installation position of the positioning rod 2 and its stability during use, thus guaranteeing product quality. In addition, by opening adjustment holes 23 arranged in a strip shape on the positioning rod 2, adjustment is achieved through the clearance space of the adjustment holes 23 cooperating with the fixing holes 322 on the adapter block 3, making the structure more flexible.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
