Description

Technical Field

[0001] This utility model relates to the field of jig technology, specifically to a radiator assembly jig. Background Technology

[0002] A jig is an auxiliary tool widely used in fields such as mechanical assembly and electronic manufacturing. It is mainly used for positioning, fixing or guiding processing and assembly operations to improve production accuracy and efficiency. Jigs are usually divided into process assembly jigs, project testing jigs and circuit board testing jigs. In the process of heat sink assembly, especially when pressing the heat sink to the PCB board, it is necessary to ensure uniform pressure and accurate positioning to avoid damage to components or poor contact due to excessive pressure or misalignment.

[0003] Existing radiator assembly fixtures mostly use simple machinery and manual pressing methods, which have problems such as inaccurate pressure control, inconvenient positioning, and poor adjustment flexibility, resulting in low assembly efficiency. Utility Model Content

[0004] Therefore, this utility model provides a radiator assembly fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a radiator assembly fixture, including a base plate, a plurality of pressing mechanisms on the top of the base plate, and a fixing component on the top of the base plate; The pressing mechanism includes a fixed plate, a fixed block fixedly mounted on one side of the fixed plate, a sliding sleeve fixedly mounted on the bottom of the fixed block, a handle movably connected to the top of the fixed block via a pivot, connecting arms movably connected to both sides of the handle via pivots, a push rod movably connected between the two connecting arms via a pivot, the push rod passing through the sliding sleeve and slidably connected to the sliding sleeve, a U-shaped plate fixedly connected to one end of the push rod, a pressure plate fixedly mounted on the bottom of the U-shaped plate, a pressure sensor mounted on one side of the pressure plate, and a limiting component mounted on one side of the fixed plate.

[0006] Preferably, the limiting component includes two reinforcing plates, which are fixedly connected to a fixed plate.

[0019] See attached document Figure 1 - Appendix Figure 5 The present invention provides a radiator assembly fixture, including a base plate 1, a plurality of pressing mechanisms on the top of the base plate 1, and a fixing component on the top of the base plate 1; The pressing mechanism includes a fixed plate 6, a fixed block 14 fixedly mounted on one side of the fixed plate 6, a sliding sleeve 15 fixedly mounted on the bottom of the fixed block 14, a handle 17 movably connected to the top of the fixed block 14 via a pivot, connecting arms 18 movably connected to both sides of the handle 17 via pivots, a top rod 16 movably connected between the two connecting arms 18 via a pivot, the top rod 16 passing through the sliding sleeve 15 and slidably connected to the sliding sleeve 15, a U-shaped plate 12 fixedly connected to one end of the top rod 16, a pressure plate 11 fixedly mounted at the bottom of the U-shaped plate 12, a pressure sensor 13 mounted on one side of the pressure plate 11, a limiting component on one side of the fixed plate 6, and a protective sleeve 19 covering the outside of the handle 17; In this embodiment, the pressure sensor 13 is a ZemicH3-C3-500N-3B model. The operator holds the protective sleeve 19 on the outside of the handle 17 (the protective sleeve increases friction and avoids hand fatigue), and rotates the handle 17. The handle 17 rotates around the pivot at the connection point with the fixed block 14, driving the connecting arms 18 on both sides to move synchronously. One end of the connecting arm 18 rotates with the handle 17, and the other end pulls the push rod 16 downward along the inner cavity of the sliding sleeve 15 through the pivot (the sliding sleeve guides and limits the push rod to prevent it from shifting during movement). The bottom of the push rod 16 drives the pressure plate 11 to move downward synchronously through the U-shaped plate 12 until the pressure plate 11 contacts the top of the heat sink and applies pressure. During this process, the pressure sensor 13 installed on one side of the pressure plate 11 detects the current pressing force in real time and transmits the data to the external display terminal. The operator can adjust the pressing force according to the feedback of the pressure sensor to ensure that the pressure meets the assembly standards (avoiding poor contact due to insufficient pressure and preventing damage to the PCB board or heat sink due to excessive pressure). To achieve the limiting purpose, this device employs the following technical solution: The limiting component includes two reinforcing plates 5, which are fixedly connected to a fixed plate 6. Two connecting plates 8 are fixedly mounted on one side of each reinforcing plate 5, and a sliding rod 9 is fixedly mounted between the two connecting plates 8. A sliding seat 10 is sleeved on the outside of the sliding rod 9, and the sliding seat 10 is fixedly connected to a pressure plate 11. The sliding rod 9 and the sliding seat 10 are slidably connected. Multiple slots 3 are formed on the surface of the base plate 1, and these slots 3 match the fixed plate 6 and the sliding seat 10. The pressure plate 11 is in contact with the fixed plate 6. The two sides of the pressure plate 11 are slidably connected to the slide rod 9 on the reinforcing plate 5 through the slide seat 10. The cooperation between the slide rod and the slide seat further restricts the movement trajectory of the pressure plate 11, ensuring that the pressure plate always keeps horizontally pressing down, avoiding the problem of skewed pressing caused by uneven force. Align the fixed plate 6 of each pressing mechanism and the reinforcing plate 5 integrated on one side with the preset slot 3 on the surface of the base plate 1, and push it into the appropriate position along the slot 3. The size of the slot 3 is adapted to the bottom of the fixed plate 6 and the slide seat 10, which can initially restrict the lateral displacement of the pressing mechanism. To achieve the purpose of fixation, the device adopts the following technical solution: The fixing component includes a connecting shell 4, which is fixedly disposed on the top of the base plate 1. A threaded rod 21 is connected to one side of the connecting shell 4 via a bearing. One end of the threaded rod 21 is connected to the top of the base plate 1 via a bearing. A knob 20 is fixedly connected to one end of the threaded rod 21. A retaining plate 23 is threadedly fitted onto the outside of the threaded rod 21. The retaining plate 23 slides inside the connecting shell 4. A grooved plate 2 is fixedly disposed on one side of the fixing plate 6. 2. The clamping plate 23 presses on the top of the grooved plate 22. The knob 20 of the rotating fixing component is rotated. The knob 20 drives the threaded rod 21 fixedly connected to it to rotate under the bearing support of the connecting shell 4 and the bottom plate 1. Since the clamping plate 23 is engaged with the threaded rod 21 through the thread, and the clamping plate 23 is limited by the inner cavity of the connecting shell 4 and cannot rotate with the threaded rod 21, the rotation of the threaded rod 21 is converted into the vertical downward movement of the clamping plate 23 until the clamping plate 23 is embedded in the groove of the grooved plate 22 on one side of the fixing plate 6 and pressed tightly, thus completing the rapid fixing of the pressing mechanism. To achieve the purpose of workpiece positioning and placement, this device adopts the following technical solution: two slide rails 24 are fixedly provided on the top of the base plate 1, a carrier plate 2 is provided on the top of the base plate 1, and multiple sliders 7 are fixedly provided on the bottom of the carrier plate 2. The sliders 7 slide outside the slide rails 24, and the PCB board to be assembled is placed stably on the preset positioning area on the surface of the carrier plate 2. Then, the heat sink is aligned with the position to be pressed on the PCB board. Holding the handles on both sides of the carrier plate 2, the carrier plate 2 is pushed to slide along the two slide rails 24 on the top of the base plate 1 through the multiple sliders 7 at the bottom until the carrier plate 2 moves the workpiece to the working position directly below the pressing mechanism. The cooperation between the slide rails and the sliders not only reduces the pushing resistance, but also ensures that the workpiece is accurately positioned each time through the guiding effect of the slide rails, avoiding positional deviations when placed manually.

[0020] The usage process of this utility model is as follows: Pre-assembly and debugging stage of the fixture: First, according to the size and specifications of the heat sink and PCB board to be assembled, select an appropriate number of pressing mechanisms. Align the fixing plate 6 and the reinforcing plate 5 integrated on one side of each pressing mechanism with the pre-set slot 3 on the surface of the base plate 1, and push it into the appropriate position along the slot 3. The size of the slot 3 is adapted to the bottom of the fixing plate 6 and the slide 10, which can initially limit the lateral displacement of the pressing mechanism. Then, rotate the knob 20 of the fixing component. The knob 20 drives the threaded rod 21 fixedly connected to it to rotate under the bearing support of the connecting shell 4 and the base plate 1. Since the clamping plate 23 is engaged with the threaded rod 21 through the thread, and the clamping plate 23 is limited by the inner cavity of the connecting shell 4 and cannot rotate with the threaded rod 21, the rotation of the threaded rod 21 is converted into the vertical downward movement of the clamping plate 23 until the clamping plate 23 is embedded in the groove of the groove plate 22 on one side of the fixing plate 6 and pressed tightly, thus completing the rapid fixing of the pressing mechanism. Workpiece positioning and placement stage: The PCB board to be assembled is placed stably on the preset positioning area on the surface of the carrier board 2. Then, the heat sink is aligned with the position to be pressed on the PCB board. Hold the handles on both sides of the carrier board 2 and push the carrier board 2 to slide along the two slide rails 24 on the top of the base plate 1 through the multiple sliders 7 at the bottom until the carrier board 2 moves the workpiece to the working position directly below the pressing mechanism. The cooperation between the slide rail and the slider not only reduces the pushing resistance, but also ensures that the workpiece can be accurately placed each time through the guiding effect of the slide rail, avoiding positional deviation when placed manually. Manual pressing and pressure monitoring stage: The operator holds the protective sleeve 19 on the outside of the handle 17 (the protective sleeve increases friction and prevents hand fatigue), and rotates the handle 17. The handle 17 rotates around the pivot at the connection point with the fixed block 14, driving the connecting arms 18 on both sides to move synchronously. One end of the connecting arm 18 rotates with the handle 17, and the other end pulls the push rod 16 downward along the inner cavity of the sliding sleeve 15 through the pivot (the sliding sleeve guides and limits the push rod to prevent it from shifting during movement). The bottom of the push rod 16 drives the pressure plate 11 to move downward synchronously through the U-shaped plate 12 until the pressure plate 11 contacts the top of the radiator. Pressure is applied, and during this process, the pressure sensor 13 installed on one side of the pressure plate 11 detects the current pressing force in real time and transmits the data to an external display terminal. The operator can adjust the pressing force according to the feedback of the pressure sensor to ensure that the pressure meets the assembly standard (avoiding poor contact due to insufficient pressure, and preventing damage to the PCB board or heat sink due to excessive pressure). At the same time, the two sides of the pressure plate 11 are slidably connected to the slide rod 9 on the reinforcing plate 5 through the slide block 10. The cooperation between the slide rod and the slide block further restricts the movement trajectory of the pressure plate 11, ensuring that the pressure plate always remains horizontally pressed down, avoiding the problem of skewed pressing caused by uneven force.
