Description

Technical Field

[0001] This invention relates to the field of hot riveting equipment technology, specifically a hot riveting device for fixing columns of CCS plastic brackets for power batteries. Background Technology

[0002] Plastic hot riveting technology refers to the technology used to connect components made of different materials; it enables the connection between thermosetting and thermoplastic components; or to connect plastic components to metal. It utilizes pre-existing plastic rivets, ribs, and studs on molded parts; these rivets are pressed through pre-drilled holes in stamped metal sheets; the protruding parts of the rivets are softened by controlled heat melting, then pressed and cooled by a special metal forming head to reshape and clamp them. Using rivet heads of specific shapes, various riveting techniques can be achieved, including countersunk riveting, flush riveting, hemispherical riveting, arc-flange riveting, rib-like riveting, mechanical forging, and edge-folding inlaying. This allows for the mechanical riveting and assembly of materials of different types. The resulting connections are less prone to brittleness, aesthetically pleasing, strong, and well-sealed, thus achieving optimal structural design. It fully utilizes the best combination of the mechanical properties of various materials, greatly improving the performance of the overall components. The overall structure is impact-resistant, achieving a perfect fit. It is particularly suitable for environments with long-term mechanical vibration, large variations in ambient temperature and humidity, and extremely harsh natural environments.

[0003] Current hot riveting processes involve single-head manual operation. Typically, 10-20 plastic brackets require manual precision during hot riveting. This is especially problematic when manufacturing CCS plastic brackets for power batteries using a single-head hot riveting method. The conventional method involves inconsistent riveting height and timing, making it difficult to achieve the required riveting height tolerance of ±0.5mm and dimensional offset of ±0.5mm. This single-head manual operation results in low production efficiency, wasted capacity, and low precision. Summary of the Invention

[0004] The technical problem to be solved by this invention is that the hot riveting of the CCS plastic bracket of the power battery is carried out by a single-head hot riveting method. However, the existing conventional single-head manual hot riveting is difficult to coordinate in terms of processing height and time, resulting in low production efficiency, wasted capacity and low precision.

[0005] To solve the above problems, the technical solution adopted by the present invention is as follows: a hot riveting device for fixing columns of CCS plastic brackets for power batteries, comprising a working platform for placing plastic brackets and a movable processing platform set directly above the working platform; the working platform is provided with movable positioning magnetic strips for limiting the position of the plastic brackets, and fixing columns are vertically fixed at the four corners of the working platform; the four corners of the movable processing platform are movably mounted on the fixing columns via timing control cylinders; the working platform is provided with a timing trigger for contacting the movable processing platform to start the action, and the timing trigger is connected to and controls the timing control cylinders; the movable processing platform has a vertically penetrating working platform groove, and multiple movable fixing plates are arranged in the working platform groove; multiple soldering iron placement slots corresponding to the positions of the fixing columns of the plastic brackets are provided on the movable fixing plates, and temperature-controlled soldering irons for hot riveting are placed in the soldering iron placement slots; horizontal adjustment components and vertical adjustment components for adjusting the horizontal plane and fixing the position are respectively provided between the movable fixing plates and the movable processing platform.

[0006] The beneficial effects of the present invention are as follows: the plastic bracket hot riveting device of the present invention can realize multi-head operation, control the time, height, temperature and horizontal position accuracy, and can realize rapid operation for different plastic bracket fixing columns, and is easy to operate; at the same time, it is applicable to any graphic position change, and achieves multi-head integrated hot riveting molding.

[0007] As a further improvement of the present invention, the technical problem to be solved is: how to implement specific timing trigger control functions.

[0008] To solve the above-mentioned technical problems, the present invention further improves the technical solution as follows: the timing trigger includes an adjustable scale limit switch that can be triggered by collision and is set on the working platform and located directly below the movable processing platform; the adjustable scale limit switch is connected to a controllable timer through a timing sensor, and the controllable timer is connected to and controls the timing control cylinder to drive the movable processing platform to move on the fixed column.

[0009] The beneficial effects of the above improvements are as follows: when the mobile work platform is pressed down and contacts the adjustable scale limit switch, the timing sensor sends a signal to the controllable timer and the timing control cylinder to start working simultaneously. After the set time is reached, the timing control cylinder starts working; thus, automated timing work control is achieved.

[0010] As a further improvement of the present invention, the technical problem to be solved is: how to realize the specific position adjustment operation of the movable fixed plate on the x-axis, that is, the horizontal direction.

[0011] To solve the above-mentioned technical problems, the present invention further improves the technical solution by adopting the following: the lateral adjustment component is a fixing slot set at both ends of the movable fixed plate on a movable processing platform.

[0012] The beneficial effects of the above improvements are: a fixing slot is provided in the horizontal direction, which is used to lock and fix the movable fixing plate after the horizontal position is determined.

[0013] As a further improvement of the present invention, the technical problem to be solved is: how to realize the specific position adjustment operation of the movable fixed plate on the y-axis, that is, the longitudinal direction.

[0014] To solve the above technical problems, the present invention further improves the technical solution by adopting the following: the vertical adjustment component is a screw fixing groove provided along the length direction on the movable fixing plate, and the screw fixing groove realizes the longitudinal positioning of the movable fixing plate on the movable processing platform by fixing screws.

[0015] The beneficial effects of the above improvements are as follows: a screw fixing groove is provided longitudinally on the movable fixing plate, which is used to lock the movable fixing plate with the fixing screw after the longitudinal position is determined, thereby fixing the movable fixing plate on the movable processing platform.

[0016] As a further improvement of the present invention, the technical problem to be solved is: how to specifically realize the pneumatic control of the timing control cylinder.

[0017] To solve the above-mentioned technical problems, the present invention further improves the technical solution by providing a pneumatic valve connected to a timing control cylinder on the movable processing platform; and an air inlet pipe is connected to the pneumatic valve.

[0018] The beneficial effects of the above improvements are: after the set time is reached, the pneumatic valve connected to the timing control cylinder closes, and the movable work platform can move up to the initial position on the fixed column.

[0019] As a further improvement of the present invention, the technical problem to be solved is: how to further optimize the structure to enable automatic reset of the movable platform.

[0020] To solve the above-mentioned technical problems, the present invention further improves the technical solution by providing a compression spring for resetting between the working platform and the movable processing platform on the fixed column.

[0021] The beneficial effects of the above improvements are: the setting of the compression spring can eliminate the step of retracting the movable work platform by the timing control cylinder, and the reset operation of the movable work platform can be completed by the elastic potential energy stored in the previous compression.

[0022] As a further improvement of the present invention, the technical problem to be solved is: when the movable positioning magnetic strip limits and fixes the plastic bracket, how to avoid the materials of the related structures from being affected by the magnet in the subsequent work process.

[0023] To solve the above-mentioned technical problems, the present invention further improves the technical solution by adopting the following: the working platform is an iron platform, the movable processing platform is an aluminum platform, and the movable fixing plate is an aluminum plate.

[0024] The beneficial effects of the above improvements are: the iron work platform can attract the movable positioning magnetic strip, while the aluminum movable work platform and aluminum movable fixed plate, which do not react to the magnet, can complete the up and down movement process normally.

[0025] As a further improvement of the present invention, the technical problem to be solved is: how to avoid the lateral position adjustment being affected by the adsorption of the movable positioning magnetic strip.

[0026] To solve the above-mentioned technical problems, the present invention further improves the technical solution by adopting an aluminum card slot.

[0027] The beneficial effect of the above improvements is that the aluminum slot, which does not respond to magnets, can smoothly complete the lateral position adjustment of the movable fixing plate. Attached Figure Description
