Description

Technical Field

[0001] This invention relates to the field of computer motherboard processing technology, specifically a welding machine for computer motherboard processing and production. Background Technology

[0002] In the manufacturing process of computer motherboards, soldering is one of the core processes, and its precision and stability directly determine the electrical performance and lifespan of the motherboard. The core principle of motherboard soldering is to heat the solder material to a molten state using a soldering mechanism, forming a reliable metal connection between the motherboard pads and the pins of electronic components. This ensures stable transmission of electrical signals and secure fixation of the mechanical structure. As a connecting medium, solder must possess good electrical conductivity, thermal conductivity, and wetting properties. After heating, it must quickly fill the gaps between the pads and pins, and after cooling, form dense solder joints. It must ensure low-resistance current flow between different components to prevent signal attenuation or open circuits, while also resisting the effects of vibration, temperature changes, and other external forces during motherboard use to prevent solder joint detachment or failure.

[0003] However, existing computer motherboards often rely on traditional clamping or simple support designs for soldering, making them unsuitable for motherboards of different sizes and thicknesses. Furthermore, controlling the fixing force is difficult; insufficient force can cause slight displacement or wobbling due to solder head vibration and airflow disturbances during soldering, while excessive force can damage motherboard edge circuitry or component pins. Even when properly secured, inaccurate positioning often leads to misalignment between the motherboard and the soldering mechanism, causing solder joint misalignment, bridging, and short circuits. In severe cases, this can directly cause motherboard malfunction, significantly reducing soldering yield. After soldering, the motherboard, held in the fixing assembly, needs to be manually removed using tools or by hand. This manual operation is not only inefficient but also prone to uneven force application and direct contact between fingertips and motherboard components, causing scratches on the motherboard surface, solder joint detachment, component damage due to pressure, and pin bending, further impacting product yield. Summary of the Invention

[0004] To address the problems in the prior art, this invention provides a welding machine for computer motherboard manufacturing.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a welding machine for computer motherboard processing and production, including a base, on which a motion module is slidably mounted; a lifting module is slidably mounted on the top of the motion module; a soldering mechanism is rotatably mounted on the lifting module; two support mechanisms are symmetrically mounted on the top of the base; a base plate is fixed on the support mechanism; and a limit mechanism and a contact mechanism are fixed on the base plate.

[0006] Specifically, the limiting mechanism includes locking posts and abutment plates. Locking posts are fixedly connected to the four corners of the base plate, and pads are adhered to the locking posts. Abutment plates are rotatably installed on the top of the locking posts, and a lever is fixedly connected to the abutment plates. Locking plates are engaged between the two sets of locking posts, and the locking plates are tightly fitted to the top of the pads. Slots are symmetrically opened on the locking plates, and inserts are engaged in the slots. A pressure plate is fixedly connected between the two inserts, and the top of the pressure plate abuts against the abutment plates. Several through slots are opened in both the pressure plate and the locking plates. The pads are made of elastic rubber material, and anti-slip textures are opened on the top of the pads. The bottom of the locking plates is tightly fitted with the anti-slip textures. The inserts are arranged with an arc-shaped structure, and the inner wall of the locking plates near the slots is tightly fitted with the arc surface of the inserts. The height of the inserts is greater than the depth of the slots.

[0007] Specifically, the base has symmetrical sliding grooves on both sides, and a movable seat is slidably connected in the sliding grooves. A drive motor is fixedly installed at one end of the base, and a screw is fixedly connected to the output end of the drive motor. The screw is threadedly connected to the movable seat, and the lifting module is fixed on the top of the movable seat.

[0008] Specifically, the soldering mechanism includes a coupling and a bracket. The coupling is rotatably mounted on the bottom of the lifting module, and the bracket is fixedly connected to the end of the coupling. The bracket has a slot, and two locking rods are slidably mounted in the slot. The locking rods are fixed to the bracket by bolts. The ends of the two locking rods opposite to the bolts are respectively fixed to a mounting bracket and a fixing bracket. A solder feeder is fixed on the mounting bracket, and a soldering head is fixed on the fixing bracket. Both the bracket and the slot are arc-shaped. The diameter of the locking rod is equal to the width of the slot. The locking rod penetrates the inner wall of the bracket. The mounting bracket and the fixing bracket are tightly fitted to the side wall of the bracket.

[0009] Specifically, the support mechanism includes a support base and a lead screw. Two support bases are symmetrically fixed on the top of the base. Two grooves are symmetrically opened on both sides of the support base. A lead screw is rotatably installed in the groove. A slider is threaded onto the lead screw. A support rod is fixedly connected to the slider. A base plate is fixedly connected to the top of both the slider and the support rod. A fixed seat is installed on the side wall of the base near the motion module. The ends of the two lead screws pass through the support base and the fixed seat. Guide wheels are fixedly connected to the lead screws. A belt is installed between the two guide wheels. A motor is installed on the side wall of the fixed seat. The output end of the motor is fixedly connected to one of the lead screws through a coupling. Several grooves are equidistantly opened in a ring on the side wall of the guide wheel. The belt is provided with protrusions that match the grooves. The guide wheel is located between the support base and the fixed seat.

[0010] Specifically, the abutment mechanism includes hydraulic rods and a connecting plate. Two hydraulic rods are symmetrically fixed at the position between the two sets of locking posts on the base plate. The connecting plate is fixedly installed at the telescopic end of the hydraulic rods. Several connecting rods are fixedly fixed at equal intervals on both sides of the connecting plate. Abutment blocks are fixedly connected to the ends of the connecting rods. Rubber pads are adhered to the abutment blocks. The two sets of connecting rods are symmetrically installed on the side wall of the connecting plate. The abutment blocks and rubber pads are both vertically installed at the bottom of the through groove in the locking plate, and the diameter of the rubber pad is smaller than the length of the abutment block.

[0011] The beneficial effects of this invention are: (1) The welding machine for computer motherboard processing and production described in this invention has a support mechanism that can provide stable support for the base plate, ensuring that the base plate remains horizontal and stable during the welding operation. The limiting mechanism can accurately and firmly position and fix the computer motherboard, effectively preventing the motherboard from shifting or shaking during the welding process. That is: the card plate is installed between the card posts fixed at the four corners of the base plate. The bottom of the card plate will be tightly fitted with the pad on the card post. The pad is made of elastic material and has anti-slip texture on the top, which can enhance the stability of the card plate installation. The computer motherboard to be processed is placed into the through slot opened in the card plate in sequence. The motherboard is fitted in the card plate. Then, the pressure plate is precisely fitted with the slot on the card plate through the plugs fixed on both sides. The tight fit between the plugs and the slot ensures the positioning accuracy of the pressure plate and avoids the pressure plate shifting and affecting the fixing effect. Then, the top of the card post is pushed to press the plate. The lever on the top easily drives the abutment plate to rotate around the locking post, so that the abutment plate firmly contacts the top of the pressure plate to achieve locking. Through the multi-directional cooperation of the locking post, locking plate, and pressure plate, a firm limit is formed on the computer motherboard, effectively preventing the motherboard from shifting or shaking during the welding process. A fixed seat is installed on the side of the support base near the motion module. A motor is installed on the fixed seat. The motor is fixedly connected to a lead screw installed in the support base. Both lead screws are rotatably installed in the slide groove opened in the support base, and guide wheels are fixed on the lead screws. The two guide wheels are driven by belt. When the guide wheels rotate, the lead screw drives the slider connected to it to slide along the inner wall of the support base. A support rod is fixed on the slider. Both the support rod and the slider are fixedly connected to the bottom end of the base plate. When the base plate slides on the support base, it can transport the fixed motherboard to the part near the welding head, which facilitates the subsequent processing of the motherboard.

[0012] (2) The welding machine for computer motherboard processing and production described in this invention can flexibly achieve precise matching between the soldering mechanism and the welding requirements of the computer motherboard through the motion module and the lifting module. It can stably complete the collaborative operation of solder feeding and welding, effectively ensuring the stability and accuracy of the welding process and avoiding welding offset problems. That is: the sliding grooves on both sides of the machine base guide and limit the moving seat on the motion module. The drive motor at one end of the machine base is started, and the drive motor drives the screw to rotate. By utilizing the threaded connection between the screw and the moving seat, the rotational motion of the motor is converted into the smooth linear motion of the moving seat, so that the motion module can drive the lifting module at the top to move, thereby facilitating the rapid adjustment of the relative position of the soldering mechanism and the computer motherboard in the horizontal direction to meet the welding requirements of different horizontal positions of the motherboard. Subsequently, the lifting module can drive the soldering mechanism to perform vertical height adjustment, and can accurately control the soldering mechanism and the motherboard according to the welding requirements such as the thickness of the computer motherboard and the depth of the solder joint. The vertical spacing between the boards ensures the compatibility between the solder head and the solder joint, laying the foundation for stable welding. Simultaneously, the rotating shaft at the bottom of the lifting module allows the bracket to rotate flexibly. Combined with the arc-shaped bracket and slot, the clamping rod, whose diameter is equal to the slot width, can slide stably along the slot. Bolts then fix the clamping rod to the bracket, achieving precise positioning. This facilitates adjustment of the relative positions of the mounting bracket and the fixed bracket, which are respectively fixed to the ends of the clamping rod. The solder feeder on the mounting bracket and the solder head on the fixed bracket can be adjusted to the optimal fit according to welding requirements, ensuring precise coordination between solder feeding and welding actions. Furthermore, the design of the clamping rod penetrating the inner wall of the bracket, and the mounting bracket and fixed bracket fitting tightly against the side wall of the bracket, effectively prevents component shifting and shaking during welding, further improving welding stability and accuracy. This achieves flexible and precise adaptation between the soldering mechanism and the welding requirements of the computer motherboard, stably completing the coordinated operation of solder feeding and welding, successfully avoiding welding offset problems.

[0013] (3) The welding machine for computer motherboard processing and production described in this invention, after the motherboard is welded, the rotating limiting mechanism can lose its limiting effect on the motherboard. At this time, the abutting mechanism is activated and moves towards the bottom of the motherboard, so that it generates an upward pushing force on the motherboard and pushes the motherboard out of the limiting mechanism, thereby facilitating the quick disassembly of the processed motherboard. That is, after the motherboard is welded, it is only necessary to rotate the abutment plate at the top of the locking post by the lever so that the abutment plate no longer abuts the pressure plate. At this time, the pressure plate loses its limiting effect on the motherboard. Then, the hydraulic rod is activated, and the hydraulic rod pushes the connecting plate towards the bottom of the motherboard. The connecting plate drives the connecting rods on both sides to move synchronously, thereby causing the abutment at the end of the connecting rod and its surface to move together. The bonded rubber pads move together towards the bottom of the motherboard, generating an upward thrust. The rubber pads are made of elastic material, which not only prevents the abutment from directly contacting the bottom of the motherboard and causing damage, but also increases contact friction to ensure a stable pushing process. At the same time, the abutment and the rubber pads are vertically aligned with the through slots in the card plate, which can accurately act on the bottom of the motherboard to achieve a smooth push, smoothly pushing the motherboard out of the limiting mechanism composed of card posts, card plates, and pressure plates. The entire process does not require manual removal of the motherboard, which not only avoids scratches and damage to the motherboard that may be caused by manual operation, but also greatly saves disassembly time and effectively improves the disassembly efficiency after motherboard processing, saving time costs for subsequent processing or testing.

[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, the present invention discloses a welding machine for computer motherboard processing and production, comprising a base 1, on which a motion module 2 is slidably mounted; a lifting module 3 is slidably mounted on the top of the motion module 2; a soldering mechanism 4 is rotatably mounted on the lifting module 3; two support mechanisms 5 are symmetrically mounted on the top of the base 1; a base plate 6 is fixed on the support mechanism 5; and a limit mechanism 7 and a contact mechanism 8 are fixed on the base plate 6.

[0019] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, the limiting mechanism 7 includes locking posts 701 and abutment plates 702. Locking posts 701 are fixedly connected to the four corners of the base plate 6. Pads 708 are adhered to the locking posts 701. Abutment plates 702 are rotatably mounted on the top of each locking post 701. A lever 703 is fixedly connected to the abutment plate 702. A locking plate 705 is engaged between the two sets of locking posts 701. The top of the locking plate 705 is tightly fitted to the pads 708, thus engaging the locking plate 705 between the locking posts 701 fixed at the four corners of the base plate 6. 5. The bottom of the plate 705 will fit tightly against the pad 708 on the locking post 701. The pad 708 is made of elastic material and has anti-slip texture on the top, which can enhance the stability of the installation of the locking plate 705. The locking plate 705 has symmetrical slots 707, and the slots 707 are fitted with inserts 706. A pressure plate 704 is fixedly connected between the two inserts 706. The top of the pressure plate 704 abuts against a stop plate 702. By moving the lever 703 on the stop plate 702 at the top of the locking post 701, the stop plate 702 can be easily rotated around the locking post 701. This design ensures that the abutment plate 702 firmly contacts and locks against the top of the pressure plate 704. Through the multi-directional cooperation of the locking post 701, locking plate 705, and pressure plate 704, a secure restraint is formed on the computer motherboard, effectively preventing displacement or shaking during soldering. Furthermore, both the pressure plate 704 and locking plate 705 have several through slots. The pad 708 is made of elastic rubber, with anti-slip textures on its top. The bottom of the locking plate 705 fits tightly against these anti-slip textures. The insert 706 has an arc-shaped structure. The inner wall of the card plate 705 near the slot 707 is tightly fitted with the arc surface of the insert block 706. The computer motherboard to be processed is placed into the through slot opened in the card plate 705 in sequence. The motherboard is locked in the card plate 705. Then, the pressure plate 704 is precisely locked into the slot 707 on the card plate 705 by the insert blocks 706 fixed on both sides. The tight fit between the insert blocks 706 and the slot 707 ensures the positioning accuracy of the pressure plate 704 and avoids the pressure plate 704 from shifting and affecting the fixing effect. Moreover, the height of the insert block 706 is greater than the groove depth of the slot 707.

[0020] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, the base 1 has symmetrical sliding grooves on both sides, and a movable seat is slidably connected in the sliding grooves. A drive motor is fixedly installed at one end of the base 1, and a screw is fixedly connected to the output end of the drive motor. When the drive motor at one end of the base 1 is started, the drive motor drives the screw to rotate. By utilizing the threaded connection between the screw and the movable seat, the rotational motion of the motor is converted into the smooth linear motion of the movable seat, thereby enabling the motion module 2 to drive the lifting module 3 at the top to move. The screw is threadedly connected to the movable seat, and the lifting module 3 is fixed to the top of the movable seat.

[0021] Specifically, such as Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the soldering mechanism 4 includes a connecting shaft 401 and a bracket 402. The connecting shaft 401 is rotatably mounted on the bottom of the lifting module 3. The bracket 402 is fixedly connected to the end of the connecting shaft 401. A slot 408 is provided in the bracket 402. Two locking rods 407 are slidably mounted in the slot 408. The locking rods 407 are fixed to the bracket 402 by bolts. A mounting bracket 403 and a fixing bracket 405 are respectively fixed to the ends of the two locking rods 407 away from the bolts. A solder feeder 404 is fixed on the mounting bracket 403. The connecting shaft 401 can drive the bracket 402 to rotate flexibly. With the arc-shaped structure of the bracket 402 and the slot 408, the locking rods 407, whose diameter is equal to the width of the slot 408, can slide stably along the slot 408. The clamping rod 407 is then fixed to the bracket 402 with bolts, achieving precise positioning of the clamping rod 407 on the bracket 402. This facilitates adjustment of the relative positions of the mounting bracket 403 and the fixing bracket 405, which are respectively fixed to the end of the clamping rod 407. This allows the solder feeder 404 on the mounting bracket 403 and the solder head 406 on the fixing bracket 405 to be adjusted to the optimal matching distance according to the welding requirements, ensuring precise coordination between solder feeding and welding actions. The solder head 406 is fixed on the fixing bracket 405. Both the bracket 402 and the slot 408 are arc-shaped structures. The diameter of the clamping rod 407 is equal to the width of the slot 408. The clamping rod 407 penetrates the inner wall of the bracket 402. The mounting bracket 403 and the fixing bracket 405 are tightly fitted to the side wall of the bracket 402.

[0022] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 8 and Figure 9As shown, the support mechanism 5 includes a support base 501 and a lead screw 503. Two support bases 501 are symmetrically fixed to the top of the base 1. Two grooves are symmetrically formed on both sides of each support base 501, and a lead screw 503 is rotatably mounted in each groove. A slider 504 is threaded onto the lead screw 503, and a support rod 502 is fixedly connected to the slider 504. A base plate 6 is fixedly connected to the top of both the slider 504 and the support rod 502. A fixed seat is installed on the side wall of the base 1 near the motion module 2. The ends of the two lead screws 503 penetrate the support bases 501 and the fixed seat, and guide wheels are fixedly connected to the lead screws 503. The lead screws 503 drive the guide wheels... The slider 504 connected by the thread slides along the inner wall of the support base 501. A support rod 502 is fixed on the slider 504. Both the support rod 502 and the slider 504 are fixedly connected to the bottom end of the base plate 6. When the base plate 6 slides on the support base 501, it can transport the fixed main board to a position close to the welding head 406, which facilitates the subsequent processing of the main board. A belt is installed between the two guide wheels. A motor is installed on the side wall of the fixed base. The output end of the motor is fixedly connected to a lead screw 503 through a coupling. The side wall of the guide wheel is provided with several grooves in an annular shape at equal intervals. The belt is provided with protrusions that match the grooves. The guide wheel is located between the support base 501 and the fixed base.

[0023] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the abutment mechanism 8 includes hydraulic rods 801 and connecting plates 804. Two hydraulic rods 801 are symmetrically fixed to the base plate 6 at the position between the two sets of locking posts 701. Connecting plates 804 are fixedly installed at the telescopic ends of the hydraulic rods 801. Several connecting rods 805 are equidistantly fixed to both sides of the connecting plate 804. Abutment blocks 802 are fixedly connected to the ends of the connecting rods 805. The hydraulic rods 801 push the connecting plate 804 towards the bottom of the main plate, causing the connecting plate 804 to move synchronously with the connecting rods 805 on both sides, thereby causing the abutment blocks 802 at the ends of the connecting rods 805 to move. Together with the rubber pad 803 adhered to its surface, it moves towards the bottom of the main board and generates an upward thrust; the abutment 802 is adhered to the rubber pad 803, and the two sets of connecting rods 805 are symmetrically installed on the side wall of the connecting plate 804. The abutment 802 and the rubber pad 803 are both vertically installed at the bottom of the through groove in the clamping plate 705. The abutment 802 and the rubber pad 803 are vertically aligned with the through groove in the clamping plate 705, which can accurately act on the bottom of the main board to achieve a stable push, and smoothly push the main board out of the limiting mechanism 7 composed of the clamping post 701, the clamping plate 705, the pressure plate 704, etc.; and the diameter of the rubber pad 803 is smaller than the length of the abutment 802.

[0024] In use, the present invention firstly involves attaching the card plate 705 between the four corner posts 701 fixed to the base plate 6. The bottom of the card plate 705 will fit tightly against the pads 708 on the posts 701. The pads 708 are made of elastic material and have anti-slip textures on the top, which enhances the stability of the card plate 705. The computer motherboard to be processed is then placed into the through slots opened in the card plate 705, and the motherboard is secured within the card plate 705. Subsequently, the pressure plate 704 is precisely engaged with the slots 707 on the card plate 705 by the inserts 706 fixed on both sides. The tight fit between the inserts 706 and the slots 707 ensures the positioning accuracy of the pressure plate 704 and prevents the pressure plate 704 from shifting and affecting the fixing effect. Then, by moving the lever 703 on the top abutment plate 702 of the posts 701, the abutment plate 702 is easily rotated around the posts 701, so that the abutment plate 702 is firmly against the top of the pressure plate 704 to achieve locking. 01. The multi-directional cooperation of the clamping plate 705 and the pressure plate 704 forms a firm limit on the computer motherboard, effectively preventing the motherboard from shifting or shaking during the welding process; a fixed seat is installed on the side of the support base 501 near the motion module 2, and a motor is installed on the fixed seat. The motor is fixedly connected to a lead screw 503 installed in the support base 501. Both lead screws 503 are rotatably installed in the sliding groove opened in the support base 501, and guide wheels are fixed on the lead screws 503. The two guide wheels are driven by belt. When the guide wheels rotate, the lead screw 503 will drive the slider 504 threadedly connected to it to slide along the inner wall of the support base 501. A support rod 502 is fixed on the slider 504. Both the support rod 502 and the slider 504 are fixedly connected to the bottom end of the base plate 6. When the base plate 6 slides on the support base 501, it can transport the fixed motherboard to the part near the welding head 406, which facilitates the subsequent processing of the motherboard; The sliding slots on both sides of the base 1 guide and limit the movement of the movable seat on the motion module 2. The drive motor at one end of the base 1 is activated, causing the screw to rotate. Utilizing the threaded connection between the screw and the movable seat, the rotational motion of the motor is converted into smooth linear motion of the movable seat. This allows the motion module 2 to move the top lifting module 3, facilitating rapid adjustment of the horizontal relative position of the soldering mechanism 4 and the computer motherboard to meet the soldering requirements of different horizontal positions on the motherboard. Subsequently, the lifting module 3 can drive the soldering mechanism 4 to perform vertical height adjustment. Based on the thickness of the computer motherboard and the depth of the solder joints, it can precisely control the vertical distance between the soldering mechanism and the motherboard, ensuring the compatibility of the soldering head 406 with the solder joints and laying the foundation for stable soldering. Simultaneously, the rotating shaft 401 at the bottom of the lifting module 3 can drive the bracket 402 to rotate flexibly. Combined with the arc-shaped bracket 402 and the slot 408, this allows... The clamping rod 407, with a diameter equal to the width of the slot 408, can slide stably along the slot 408. The clamping rod 407 is then fixed to the bracket 402 by bolts, achieving precise positioning of the clamping rod 407 on the bracket 402. This facilitates the adjustment of the relative positions of the mounting bracket 403 and the fixing bracket 405, which are respectively fixed to the end of the clamping rod 407. This allows the solder feeder 404 on the mounting bracket 403 and the solder head 406 on the fixing bracket 405 to be adjusted to the optimal fitting distance according to the welding requirements, ensuring precise coordination between solder feeding and welding actions. Furthermore, the design of the clamping rod 407 penetrating through the inner wall of the bracket 402 and the mounting bracket 403 and the fixing bracket 405 being tightly fitted to the side wall of the bracket 402 effectively prevents the components from shifting or shaking during the welding process, further improving the stability and accuracy of the welding. This achieves flexible and precise adaptation between the soldering mechanism 4 and the welding requirements of the computer motherboard, stably completing the coordinated operation of solder feeding and welding, and successfully avoiding welding offset problems. After the motherboard is soldered, simply rotate the abutment plate 702 at the top of the locking post 701 using the lever 703, so that the abutment plate 702 no longer abuts against the pressure plate 704. At this time, the pressure plate 704 loses its limiting function on the motherboard. Then, activate the hydraulic rod 801, which pushes the connecting plate 804 towards the bottom of the motherboard. The connecting plate 804 drives the connecting rods 805 on both sides to move synchronously, thereby causing the abutment block 802 at the end of the connecting rod 805 to move. Together with the rubber pad 803 adhered to its surface, it moves towards the bottom of the motherboard and generates an upward pushing force. The rubber pad 803 is made of elastic material, which can not only prevent the abutment 802 from directly contacting the bottom of the motherboard and causing damage to the motherboard, but also increase the contact friction to ensure the stability of the pushing process. At the same time, the abutment 802 and the rubber pad 803 are vertically aligned with the through slot in the card plate 705, which can accurately act on the bottom of the motherboard to achieve a smooth push, and smoothly push the motherboard out of the limiting mechanism 7 composed of the card post 701, card plate 705, pressure plate 704, etc. The whole process does not require manual removal of the motherboard, which not only avoids the scratches and damage to the motherboard that may be caused by manual operation, but also greatly saves disassembly time, effectively improves the disassembly efficiency after motherboard processing, and saves time costs for subsequent processing or testing.
