Description

Technical Field

[0001] This utility model belongs to the technical field of hot riveting fixtures, specifically relating to a general-purpose CCS hot riveting fixture. Background Technology

[0002] The CCS (Cell Contact System) circuit board is an integrated busbar used for signal acquisition in new energy electric vehicles, responsible for collecting status information from each battery. Traditional wiring harness connections are prone to errors and are messy, while hot riveting fixtures are mainly used to achieve reliable connections between the flexible board of the CCS circuit board and the aluminum busbar (aluminum conductive bus). Through the hot riveting process, the metal rivets on the flexible board or the aluminum busbar itself undergo plastic deformation under heating and pressure to form "mushroom head" shaped rivet points, thereby achieving mechanical fastening and electrical connection. The core of the universal hot riveting fixture is its ability to adapt to various product models or different riveting point positions, reducing wiring change time and costs.

[0003] Existing general-purpose hot riveting fixtures do not cool the riveted joint after riveting. If the sheet moves at this time, the riveted joint will deform, resulting in a loose connection between the soft sheet and the aluminum plate. Utility Model Content

To achieve the above objective, this utility model provides the following technical solution: it includes a base, a lower mounting frame, a placement seat, an upper mounting frame, a hot pressing seat, and a pushing component. The lower mounting frame is mounted above the base, the upper mounting frame is mounted above the lower mounting frame, the pushing component is specifically located in the cavity of the mounting frame, a power component is provided at the top of the upper mounting frame, a hot pressing seat is connected below the pushing component, a hot pressing component is provided on the hot pressing seat, the placement seat is movably connected to the base, and a cooling component is also provided inside the lower mounting frame.

[0005] The cooling component includes an air compressor installed in the lower mounting frame. The output end of the air compressor is connected to a solenoid valve, which is installed on the inner wall of the lower mounting frame. Several adjustment components are fixed on the outer wall of the lower mounting frame.

[0006] The adjustment assembly includes a bamboo tube installed on the outer wall of the lower mounting frame. One end of the bamboo tube is connected to a solenoid valve, and the other end of the bamboo tube is fixedly connected to an air nozzle.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 A general-purpose CCS hot riveting fixture includes a base 1, a lower mounting frame 2, a placement seat 3, an upper mounting frame 6, a hot pressing seat 9, and a pushing component 8. The lower mounting frame 2 is mounted above the base 1, the upper mounting frame 6 is mounted above the lower mounting frame 2, the pushing component 8 is specifically located in the cavity of the mounting frame 6, a power assembly 5 is provided on the top of the upper mounting frame 6, the hot pressing seat 9 is connected below the pushing component 8, a hot pressing component is provided on the hot pressing seat 9, the placement seat 3 is movably connected to the base 1, and a cooling component is also provided inside the lower mounting frame 2.

[0021] The cooling component includes an air compressor 7 installed in the lower mounting frame 2. The output end of the air compressor 7 is connected to a solenoid valve 12. The solenoid valve 12 is installed on the inner wall of the lower mounting frame. Several adjustment components are fixed on the outer wall of the lower mounting frame.

[0022] The adjustment assembly includes a bamboo tube 14 installed on the outer wall of the lower mounting frame. One end of the bamboo tube 14 is connected to a solenoid valve 12, and the other end of the bamboo tube 14 is fixedly connected to an air nozzle 15. The input end of the solenoid valve 12 is connected to the output end of the air compressor 7 through a pressure-resistant air pipe 11.

[0023] With the cooling components in place, in actual use, the equipment is first installed and debugged. The base and mounting frame are assembled, and the lower mounting frame 2 is securely installed on top of the base 1, ensuring the connecting bolts are tight and the overall structure is stable. The upper mounting frame 6 is then installed on top of the lower mounting frame 2, and aligned using guide pins or positioning slots to ensure the verticality of the upper and lower frames. The power component and pusher are then installed; the power component 5 is fixed to the top of the upper mounting frame 6, and its output shaft is connected to the pusher 8 via a coupling or rigid connector to ensure synchronous power transmission. The pusher 8 is installed inside the upper mounting frame cavity, and a protective plate 4 is added to its outer perimeter for protection. To prevent external interference or accidental operation by operators, the hot press base is assembled with the heat insulation structure. The hot press base 9 is connected to the bottom of the pusher 8 via a connecting block. The hot press components (such as heating pipes and thermocouples) are embedded inside the hot press base and fixed. The cooling components are installed and connected. The air compressor 7 is installed inside the lower mounting frame 2. The output end is connected to the solenoid valve 12 via a pressure-resistant air pipe 11. The solenoid valve 12 is fixed to the inner wall of the lower mounting frame. The outlet end is connected to the bamboo tube 14. An air nozzle 15 is installed at the other end of the bamboo tube. The airflow is directed by adjusting the bending angle of the bamboo tube. The solenoid valve is connected to the control system (such as a PLC) and supports manual or program-controlled start and stop.

[0024] Operation process: workpiece clamping, placing the CCS workpiece on the placement seat 3, hot riveting process, starting the power component 5, driving the pusher 8 to press down, causing the hot press seat 9 to contact the workpiece riveting point, the hot press is heated to the set temperature (e.g., 200-300℃), and the hot riveting is completed.

[0025] During the cooling phase, after the hot riveting is completed, the power unit lifts the hot pressure seat and triggers the solenoid valve 12 to open. The compressed air generated by the air compressor 7 is sprayed onto the riveting area through the bamboo tube 14 and the air nozzle 15 to achieve rapid cooling. The airflow direction and distance are adapted to different workpiece structures by adjusting the bending angle of the bamboo tube and the position of the air nozzle.

[0026] The bamboo joint tube 14 and the air nozzle 15 can be adjusted at multiple angles to meet the local cooling needs of irregularly shaped workpieces.

[0027] There are two types of power components 5: one is cylinder-driven (most common): Structure: mainly composed of a double-acting cylinder, a solenoid directional valve, a speed control valve (throttle valve), air pipes, and mounting components. The cylinder body is fixed to the top of the upper mounting frame 6 by a mounting plate, and its piston rod is directly connected downward to the pusher 8;

[0028] Working principle: Downward pressure: The control system energizes the solenoid valve, and compressed air enters the upper chamber of the cylinder through the solenoid valve, pushing the piston rod downward to provide pressure. The downward pressure speed is controlled by the speed control valve;

[0029] Return: The control system changes the solenoid valve signal, allowing compressed air to enter the lower chamber of the cylinder while exhaust is released from the upper chamber. The piston rod retracts, causing the hot press seat to rise. The return speed is controlled by another speed control valve.

[0030] Features: Simple structure, low cost, fast operation, and easy maintenance. Pressure can be set via a pressure regulating valve, but pressure accuracy and stability are relatively low.

[0031] 2. Servo Electric Cylinder Drive (High Precision Type): Structure: Mainly composed of a servo motor, driver, precision ball screw, and cylinder body. The servo motor receives pulse signals from the controller to rotate precisely, driving the ball screw via a synchronous belt or coupling, converting the rotary motion into the linear motion of the piston rod;

[0032] Working principle: Control: The position, speed, and pressure of the downward pressure are set through a program (by monitoring current feedback);

[0033] Downward pressure: The servo motor rotates at a preset speed, driving the piston rod to press down at a constant speed. Once it contacts the workpiece, the resistance increases, and the motor current (torque) rises. When the preset pressure value is reached, the motor stops and maintains that pressure for a period of time (pressure holding).

[0034] Return: After completion, the motor rotates in the opposite direction, driving the piston rod to return precisely to the preset origin position;

[0035] Features: Extremely high control precision; pressure, speed, and position can be precisely programmed; good process repeatability; capable of achieving complex press-fitting curves.

[0036] The guide rod type spring reset device is a key component that ensures the precise and stable movement of the hot press seat and its automatic return to the initial position.

[0037] Structural Composition: A complete guide rod type spring reset device typically consists of the following parts (usually four sets per set, symmetrically distributed around the bottom of the pusher): Guide Rod: A smooth, rigid metal rod (usually chrome-plated hard steel), the core guiding component of the entire device. Compression Spring: Sleeves around the outside of the guide rod, providing the elastic force required for reset. Fixed Seat: Fixed to the bottom of the pusher 8, usually containing a linear bearing or lubricated bushing, allowing the guide rod to slide smoothly up and down within it. Movable Connecting Plate: Fixedly connected to the bottom end of the guide rod, this plate is then fixed to the heat insulation plate 19. Therefore, the movement of the heat insulation plate and the heat-pressing seat 9 is synchronized with the guide rod. Limiting Structure: This may be a threaded nut at the end of the guide rod, or a retaining spring on the fixed seat, used to prevent the guide rod from completely disengaging from the fixed seat.

[0038] In the fixture, the retractable end refers to the bottom end of the guide rod and its connecting portion, as it retracts into the fixed seat.

[0039] The working principle is similar to the button mechanism of a ballpoint pen, with the core being the compression and release of the spring. Downward stroke (spring compression): The power component 5 drives the pusher 8 downwards, which in turn moves the fixed seat of all the guide rod-type reset devices at its bottom downwards. At this time, the movable connecting plate and guide rod, fixedly connected to the heat insulation plate 19, remain temporarily stationary (or move slower than the fixed seat) due to the resistance of the workpiece below. The fixed seat moves downwards relative to the guide rod, causing the compression spring sleeved outside the guide rod to be squeezed by the fixed seat and movable connecting plate, gradually storing elastic potential energy. The spring is compressed until the hot pressing seat 9 completes the hot riveting operation.

[0040] Return stroke (spring reset): After the hot riveting is completed, the power component stops applying downward force and begins to rise. The compressed spring begins to release its stored elastic potential energy and release the elastic force.

[0041] The spring force pushes the fixed seat (i.e., part of the pushing component) upwards, while simultaneously pushing the movable connecting plate (i.e., part of the heat insulation plate and the hot press seat) downwards. However, since the fixed seat is connected to the power assembly, has a larger mass, and is actively lifted, the main effect is that the spring pushes the movable connecting plate and guide rod downwards, causing the hot press seat 9 to quickly and decisively separate from the workpiece.

[0042] Guided by the spring force and the guide rod, the entire hot press smoothly returns to its initial position, ready for the next work cycle.

[0043] Furthermore, referring to Figure 1-4 As shown, it is worth noting that the bottom of the pusher 8 is fixed with a guide rod type spring reset device 18 around the perimeter, the pusher 8 is provided with a heat insulation plate 19, a connecting block is provided between the hot press seat 9 and the heat insulation plate 19, and the retracted end of the guide rod type spring reset device 18 is fixedly connected to the heat insulation plate 19.

[0044] With the setting of the guide rod type spring reset device 18, the bottom of the pusher 8 is equipped with the guide rod type spring reset device 18, and its contraction end is fixed with the heat insulation plate 19 to ensure that the hot press seat can automatically reset after being pressed down. The guide rod type spring reset device 18 pushes the hot press seat back to ensure that it is detached from the workpiece. After cooling, the riveted workpiece is taken out. The heat insulation plate 19 is installed between the hot press seat 9 and the pusher 8 to reduce the impact of heat conduction on the upper components.

[0045] Furthermore, referring to Figure 1-4 As shown, it is worth noting that the top of the placement base 3 is provided with several mounting holes, and the placement base 3 is also provided with several fixing posts 17, the bottom end of the fixing posts 17 being fixed in the mounting holes.

[0046] With the fixing post 17, the placement seat 3 is movably connected to the base 1 via a slide rail or guide mechanism, facilitating position adjustment. The fixing post 17 is inserted into the mounting hole at the top of the placement seat to position the CCS workpiece.

[0047] Furthermore, referring to Figure 1-4 As shown, it is worth noting that the outer periphery of the pusher 8 is also provided with a protective plate 4;

[0048] With the installation of the protective plate 4, it is necessary to ensure that the protective plate 4 is intact during operation to prevent high-temperature components from being exposed. The airflow direction of the air nozzle should avoid the operator to prevent blowing up debris. Regular maintenance is required, including checking the filter and pressure gauge of the air compressor 7, regularly draining condensate, cleaning residual plastic or dirt from the surface of the hot-pressed parts to maintain heat transfer efficiency, and checking the lubrication and elasticity of the guide rod type spring reset device 18.

[0049] Furthermore, referring to Figure 1-4 As shown, it is worth noting that the placement seat 3 is also provided with a protective pad 16;

[0050] The protective pad 16 is laid on the surface of the placement seat to prevent scratches on the workpiece surface.
