Abstract
Description
Technical Field
[0001] This invention relates to the field of semiconductor processing tool technology, specifically to an adjustable cleaver for narrow-pitch soldering. Background Technology
[0002] In the semiconductor processing field, as electronic devices continue to develop towards miniaturization and high integration, the spacing between solder joints on semiconductor components such as chips is getting smaller and smaller, thus requiring high-precision soldering through narrow-pitch soldering processes.
[0003] Traditional cleavers have the following shortcomings:
[0004] Firstly, regarding thermal management, the large amount of heat generated during welding is difficult to dissipate effectively, leading to excessively high temperatures at the tip of the welding tool and causing thermal deformation. This thermal deformation can cause the welding position to shift, severely affecting welding accuracy, resulting in decreased weld quality, and even defects such as incomplete welds and short circuits, thus reducing product reliability and yield.
[0005] Secondly, in narrow-pitch welding environments, the components around the welding cutter are densely packed, and the space is extremely limited. During welding, mechanical interference with adjacent components is likely to occur, leading to collisions, damaging the welding cutter and surrounding components, and affecting the normal progress of the welding work. Moreover, because the surrounding environment cannot be perceived in real time, operators find it difficult to detect potential interference risks in a timely manner, increasing the uncertainty and risk of the welding process.
[0006] Thirdly, existing wedges have a single end design, making them difficult to adapt to the needs of different welding scenarios. When welding special-shaped weld points or in confined spaces, traditional wedges cannot be flexibly adjusted, limiting their application range. Furthermore, the installation and maintenance of wedges are inconvenient; replacing the end or performing repairs requires significant time and effort, increasing production costs and timelines. To address the shortcomings of existing technologies, this invention provides an adjustable wedge for narrow-pitch welding, solving the aforementioned problems. Summary of the Invention

[0058] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0059] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0060] This invention discloses an adjustable wedge for narrow-pitch welding, according to the attached... Figure 1-12 As shown, it includes an installation part 1, a main body part 2, a telescopic part 3, a splicing part 4, a fixed bottleneck part 5, an external bottleneck part 6, a thermal management unit 9, a sensing unit 10, a blade length adjustment unit 7, and a control system 11.
[0061] Mounting part 1 is used to snap onto the mounting interface of the cleaver to achieve the initial connection between the cleaver and the welding equipment; body part 2 is fixedly connected to mounting part 1 and serves as the main support structure of the cleaver; telescopic part 3 is slidably connected to body part 2 to achieve telescopic adjustment; splicing part 4 is detachably snapped onto the end of telescopic part 3 to facilitate the replacement and maintenance of fixed bottleneck part 5.
[0062] The fixed bottleneck section 5 is fixedly connected to the splicing section 4, and its end is provided with a first end 51; the external bottleneck section 6 is detachably sleeved on the fixed bottleneck section 5 and snapped into the splicing section 4, and its end is provided with a second end 61. The chopping knife can select different end combinations according to welding requirements.
[0063] The thermal management unit 9 is integrated inside the fixed bottleneck section 5 and the external bottleneck section 6. The thermal management unit 9 is used to control the temperature during the welding process. The sensing unit 10 is located at the ends of the fixed bottleneck section 5 and the external bottleneck section 6. It is used to sense welding environment information.
[0064] The chopping blade length adjustment unit 7 is installed on the main body 2 and is used to drive the telescopic part 3 to move, so as to realize the dynamic adjustment of the chopping blade length; the control system 11 receives data from the sensing unit 10 and dynamically controls the chopping blade length adjustment unit 7 and the thermal management unit 9 to realize the intelligent control of the chopping blade.
[0065] According to the appendix Figure 12 As shown, the thermal management unit 9 further includes a miniature cooling channel 91 and a flow pump line 92 connecting to an external cooling system. The miniature cooling channel 91 of the thermal management unit 9 is spirally wrapped around the inner wall of the bottleneck section. This structure can increase the contact area between the cooling medium and the bottleneck section, thereby improving cooling efficiency. The cooling medium is an inert gas or an insulating coolant, which can be selected according to different welding materials and process requirements. The flow pump line 92 is connected to an external micro-flow pump through a quick-connect coupling, which facilitates quick replacement and maintenance, while also enabling precise control of the cooling medium flow rate.
[0066] In this embodiment, the micro-cooling channel 91 is spirally wound around the inner wall of the bottleneck section, and the flow pump pipeline 92 is made of 316 stainless steel pipe, which is connected to an external micro-flow pump through a threaded quick-connect coupling, and -10℃ argon gas is circulated in. This spiral design increases the contact area between the cooling medium and the bottleneck section, which can more effectively remove heat and suppress the thermal deformation of the first end 51 and the second end 61.
[0067] According to the appendix Figure 10 , Figure 11As shown, the sensing unit 10 is further disposed at the ends of the fixed bottleneck section 5 and the external bottleneck section 6; the sensing unit 10 includes a temperature sensor 101 and a miniature vision probe 102. The temperature sensor 101 can monitor the temperature of the end section in real time, providing temperature data to the thermal management unit 9 so that the control system 11 can adjust the flow rate of the cooling medium according to the data of the temperature sensor 101, thereby achieving precise control of the end temperature, reducing thermal deformation, and improving welding accuracy. The miniature vision probe 102 can identify the location of the weld point and the distance to adjacent components. The control system 11 uses the image information acquired by the miniature vision probe 102 to determine the welding position and the surrounding environment. When a spatial interference risk is detected, the length of the cutting tool is automatically retracted to avoid obstacles, ensuring the safe conduct of the welding process.
[0068] In this embodiment, the miniature vision probe 102 is embedded in the end walls of the first end 51 and the second end 61, and the temperature sensor 101 is mounted using a K-type thermocouple. The temperature sensor 101 can monitor the temperature of the first end 51 and the second end 61 in real time, and the miniature vision probe 102 can capture the solder joint position and the distance between surrounding components in real time. When the distance is less than a threshold set by the control system 11, an obstacle avoidance signal is triggered. By identifying the solder joint position and the distance to adjacent components through the miniature vision probe 102, when a spatial interference risk is detected, the length of the cutting tool is automatically retracted to avoid the obstacle.
[0069] According to the appendix Figure 4 As shown, the cleaver length adjustment unit 7 further includes a high-rigidity linear guide rail assembly 71, a nut seat 72, a micro motor 73, and a lead screw 74. The high-rigidity linear guide rail assembly 71 is disposed between the main body 2 and the telescopic part 3, providing stable linear motion guidance and reducing friction and shaking during the telescopic process. The nut seat 72 is fixedly connected to the high-rigidity linear guide rail assembly 71, the micro motor 73 is fixedly connected to the main body 2, and the lead screw 74 is disposed at the output end of the micro motor 73 and threadedly connected to the nut seat 72. When the micro motor 73 rotates, it drives the lead screw 74 to rotate, thereby causing the nut seat 72 to move linearly along the lead screw 74, which in turn drives the telescopic part 3 to move, thus achieving the adjustment of the cleaver length. In this embodiment, the high-rigidity linear guide rail assembly 71 uses a cross roller guide rail instead of a simple slide rail, which can reduce chatter under various working conditions and ensure the stability of high-frequency welding motion.
[0070] According to the appendix Figure 4 , Figure 6 , Figure 7As shown, the main body 2 is further provided with a telescopic groove 21, and a cylindrical body 31 is fixedly connected to the telescopic part 3. The cylindrical body 31 is slidably connected within the telescopic groove 21. This structure ensures that the telescopic part 3 slides stably on the main body 2. A lateral support rod 75 is fixedly connected to the telescopic part 3, and a support seat 76 is fixedly connected to the main body 2. The lateral support rod 75 is slidably connected to the support seat 76. The cooperation between the lateral support rod 75 and the support seat 76 provides lateral support, enhances the stability of the telescopic part 3, reduces chatter under long cantilever conditions, and ensures the stability of high-frequency welding motion.
[0071] According to the appendix Figure 6 , Figure 8 , Figure 9 As shown, furthermore, a snap-fit seat 32 is fixedly connected to the telescopic part 3, and a positioning plug 41 is fixedly connected to the splicing part 4. The positioning plug 41 is movably inserted into the snap-fit seat 32 to achieve the initial positioning and connection between the splicing part 4 and the telescopic part 3.
[0072] According to the appendix Figure 9 , Figure 10 As shown, the positioning insert 41 is further provided with a first locking groove 42, and the telescopic part 3 is provided with an active locking unit 8, which is used to lock the fixed bottleneck part 5 and the external bottleneck part 6. The active locking unit 8 includes a pressure plate 81, a lock head 82, a spring 83, a ferromagnetic block 84 and an electromagnetic coil 85.
[0073] A pressure plate 81 is rotatably connected to a locking seat 32. A lock head 82 is fixedly connected to the pressure plate 81 and movably locked into the first locking groove 42. A spring 83 is fixedly connected between the pressure plate 81 and the locking seat 32, providing elasticity to the pressure plate 81 so that the lock head 82 can be tightly locked into the first locking groove 42. A ferromagnetic block 84 is disposed on the pressure plate 81, and an electromagnetic coil 85 is disposed inside the locking seat 32 and aligned with the position of the ferromagnetic block 84. When the electromagnetic coil 85 is energized, it generates a magnetic field that repels the magnetic field of the ferromagnetic block 84, causing the lock head 82 on the pressure plate 81 to stably lock into the first locking groove 42, thus achieving locking. When the electromagnetic coil 85 is de-energized, the magnetic field of the electromagnetic coil 85 disappears. At this time, pressing the pressure plate 81 causes it to rotate, overcoming the elasticity of the spring 83 and causing the pressure plate 81 to rotate, thus disengaging the lock head 82 from the first locking groove 42, thus unlocking. This electromagnetic locking method solves the risk of mechanical locking failure under vibration and improves reliability under extreme working conditions.
[0074] According to the appendix Figure 5 , Figure 9 , Figure 10 , Figure 11As shown, further, a limiting groove 43 is provided on the positioning plug 41, and a limiting plug 62 is fixedly connected to the external bottleneck part 6. The limiting plug 62 is movably inserted into the limiting groove 43 and the snap-fit seat 32, so as to realize the initial splicing of the external bottleneck part 6 and the splicing part 4, which is convenient for docking.
[0075] According to the appendix Figure 5 , Figure 9 , Figure 10 , Figure 11 As shown, the limiting insert 62 is further provided with a second locking groove 63, and the locking head 82 is movably engaged in the second locking groove 63, so that the active locking unit 8 can simultaneously lock the fixed bottleneck part 5 and the external bottleneck part 6, improving the stability of the overall structure. When it is necessary to install or replace the external bottleneck part 6, the electromagnetic coil 85 can easily drive the ferromagnetic block 84 to drive the locking head 82 to lock or unlock the second locking groove 63, thereby realizing the quick installation or replacement of the external bottleneck part 6.
[0076] According to the appendix Figure 1 , Figure 2 As shown, the first end 51 is a straight end and the second end 61 is a bent end. The appropriate end combination can be selected according to different welding requirements, which improves the applicability of the cleaver.
[0077] According to the appendix Figure 1-12 As shown, this solution specifically addresses three major industry challenges in narrow-pitch welding: thermal deformation control, obstacle avoidance, and dynamic stability. Microchannel cooling is a cross-disciplinary application in thermal management. Through the cooperation of the micro-cooling channel 91 and the flow pump pipeline 92, the temperature of the cutting tool tip can be effectively controlled during welding, preventing welding deviation caused by thermal deformation and breaking through the bottleneck of thermal management technology in narrow-pitch welding. Visually guided closed-loop length adjustment enables autonomous tool decision-making. The micro-vision probe 102 in the sensing unit 10 can acquire welding environment information in real time. The control system 11 automatically adjusts the cutting tool length based on this information, achieving spatial interference warning, dynamic length adjustment, and thermal balance control, endowing the tool with intelligent attributes and enabling unmanned, precise operation.
[0078] According to the appendix Figure 8 , Figure 9 As shown, the actively locking unit 8, which employs electromagnetic force locking, solves the failure risk of various end caps under vibration conditions caused by traditional mechanical locking, thus improving reliability under extreme working conditions. During welding, the equipment vibrates, and traditional mechanical locking methods can loosen under vibration, leading to instability in the cleaver structure. The electromagnetic force locking method, however, achieves locking and unlocking through the interaction of the electromagnetic coil 85 and the ferromagnetic block 84, unaffected by vibration, ensuring stable operation of the cleaver under extreme conditions.
[0079] According to the appendix Figure 4As shown, the high-rigidity linear guide assembly 71, which is specifically disclosed, uses a cross roller guide instead of a simple slide rail, which can effectively reduce chatter under various working conditions and ensure the stability of high-frequency welding motion. The cross roller guide has the characteristics of high rigidity, high precision and high load capacity, and can withstand various forces during the extension and extension of the cutting tool and the welding process, ensuring that the extension part 3 slides stably on the body part 2, reducing chatter and improving welding quality.
[0080] According to the appendix Figure 1-12 As shown, it is particularly important to emphasize that this solution significantly improves thermal management capabilities, structural rigidity and stability, intelligent sensing, control, and adaptability to extreme spaces. The thermal management unit 9 effectively controls the welding temperature and prevents thermal deformation; the high-rigidity linear guide assembly 71 and the lateral support rod 75 enhance the structural rigidity and stability of the cutting tool; the sensing unit 10 and the control system 11 enable intelligent sensing and control of the cutting tool; and the active locking unit 8 and the adjustable cutting tool length improve the cutting tool's adaptability to extreme spaces.
[0081] According to the appendix Figure 1-12 As shown, it is particularly important to emphasize that the cleaver features modular installation, easy maintenance, and adjustable length. Components such as the mounting section 1, splicing section 4, fixed bottleneck section 5, and external bottleneck section 6 adopt a modular design, facilitating installation and disassembly, and making maintenance and replacement convenient. The cooperation between the telescopic section 3 and the cleaver length adjustment unit 7 enables the cleaver length to be adjustable, meeting the needs of different welding scenarios.
[0082] The working principle of this adjustable wedge for narrow-pitch welding is as follows:
[0083] In the initial positioning stage, the miniature vision probe 102 identifies the pad position, and the control system 11 calculates the optimal cutting length based on the identification result;
[0084] During the dynamic adjustment phase, the temperature sensor 101 monitors the temperature in real time during the welding process. When the temperature is higher than the set temperature, the cooling system is triggered and the control system 11 starts the cooling pump. Argon gas flows through the micro cooling channel 91 at the temperature range set by the control system 11 and at the corresponding speed. At the same time, the vision system monitors the distance of surrounding components.
[0085] During the emergency obstacle avoidance phase, when a risk of mechanical interference is detected, the micro motor 73 drives the lead screw 74 to retract the length of the chopping blade;
[0086] During the rapid changeover phase, the electromagnetic coil 85 controls the ferromagnetic block 84 to release the repulsive force, thereby pressing the pressure plate 81 to release the locking head 82 from the second locking groove 63, allowing for the replacement of the external bottleneck section 6 with a different curvature, or the replacement of the fixed bottleneck section 5 with a different form.
[0087] The steps for using this adjustable wedge for narrow-pitch welding are as follows:
[0088] Select the appropriate end combination according to the welding requirements, install the fixed bottleneck part 5 on the splicing part 4, and lock it with the active locking unit 8. Subsequently, according to actual needs, the external bottleneck part 6 can be further installed to realize small space elbow welding operation, which is suitable for a variety of narrow spacing welding scenarios.
[0089] The chopping knife is snapped into the chopping knife mounting interface via the mounting part 1, and wire is threaded into the inside of the chopping knife.
[0090] The welding equipment is started, and the welding process begins. During the welding process, the sensing unit 10 monitors the welding environment information in real time and transmits the data to the control system 11.
[0091] Based on the data from the sensing unit 10, the control system 11 dynamically controls the thermal management unit 9 and the chopping blade length adjustment unit 7 to achieve end temperature control, spatial interference early warning, and dynamic length adjustment functions.
[0092] After welding is completed, turn off the welding equipment, disassemble the cutting tool, and perform maintenance and upkeep.
[0093] The adjustable wedge for narrow-pitch welding offers the following advantages:
[0094] It effectively solves three major industry challenges in narrow-pitch welding: thermal deformation control, obstacle avoidance, and dynamic stability, thereby improving welding quality and reliability.
[0095] The micro-cooling channel 91 is a cross-disciplinary application in the field of thermal management, which can precisely control the welding temperature and prevent welding deviation caused by thermal deformation.
[0096] Visually guided closed-loop length adjustment enables the tool to make autonomous decisions, endowing it with intelligent attributes and enabling unmanned, precise operation.
[0097] The active locking unit 8 uses electromagnetic force locking, which solves the risk of mechanical locking failure under vibration and improves reliability under extreme working conditions.
[0098] The high-rigidity linear guide assembly 71 improves the structural rigidity and stability of the cleaver, ensuring the stability of high-frequency welding motion.
[0099] The cleaver features modular installation, easy maintenance, and adjustable length, making it suitable for various welding scenarios.
