Description

Technical Field

[0001] This utility model relates to the field of LED display equipment technology, and in particular to mass-produced hot riveting fixtures. Background Technology

[0002] In the LED display manufacturing industry, mass production hot riveting fixtures are a highly integrated special tooling system. They consist of a precision positioning bottom mold, a multi-riveting head heated upper mold, a pressure actuator, and an intelligent control system working together according to functional requirements. In automated production lines, they are used to simultaneously hot rivet multiple products, providing efficient and reliable mechanical connection force for plastic components, ensuring the strength and consistency of product assembly, and are one of the core equipment for ensuring the quality and efficiency of large-scale production.

[0003] Traditional hot riveting fixtures mainly consist of a single-point heating module, a manual positioning fixture, a basic pressure mechanism, and a simple frame. The operator manually adjusts the position to align the target rivet point directly under the rivet head to complete the formation of a single rivet point. If the workpiece has multiple rivet points, the workpiece needs to be moved manually multiple times, and the positioning, heating, and pressurizing processes need to be repeated point by point. The entire set of operations needs to be repeated, which is inefficient. The temperature of the rivet head drifts with continuous use and cannot be integrated into automated production lines.

[0004] Existing hot riveting fixtures mainly consist of a bottom mold supporting the workpiece to be hot riveted, a heating component that provides heat, a drive mechanism that drives the heating component, and a control system that controls the hot riveting temperature and time. Optimizing the distribution of heating elements in the heating component improves temperature uniformity, adding more precise positioning pins and limit blocks improves positioning accuracy, and adding protective baffles and emergency braking devices ensures operational safety. However, existing fixtures can only hot rivet a single product at a time, and the next product can only be riveted after the previous one is completed. This results in long production times, making it difficult to meet the high-efficiency requirements of mass production, thus reducing production efficiency and increasing production costs to some extent.

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.

[0038] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a batch hot riveting fixture, including a bottom mold 1. The bottom mold 1 serves as the basic load-bearing structure of the entire fixture, providing installation references and support for each component. A batch hot riveting mechanism 2 is provided on the upper part of the bottom mold 1. The batch hot riveting mechanism 2 is the core functional component for realizing the synchronous hot riveting operation of multiple products. An upper template 4 is provided on the upper part of the batch hot riveting mechanism 2. The upper template 4 is used to install and fix each component of the batch hot riveting mechanism 2 and transmit driving force. A fixing mechanism 3 is provided at the bottom of the upper template 4. The fixing mechanism 3 is used to firmly clamp the product placed in the mold groove 205 to prevent the product from shifting during the hot riveting process. The fixing mechanism 3 is fixedly connected to the bottom mold 1. The fixed connection between the fixing mechanism 3 and the bottom mold 1 ensures the stability of the clamping action. A positioning component 206 is provided on the upper part of the bottom mold 1. The positioning component 206 is used to ensure the relative position accuracy of the upper template 4 and the bottom mold 1 during the hot riveting operation.

[0039] The batch hot riveting mechanism 2 includes multiple hot riveting heads 201, which are execution components that directly contact the product rivet posts and perform hot riveting operations. Multiple control units 202 are fixedly connected to the rear side of the upper template 4. These control units 202 are used to independently control whether the corresponding hot riveting head 201 is working. Multiple hot riveting holes 203 are provided inside the upper template 4, providing installation and positioning references for the hot riveting heads 201. The multiple hot riveting heads 201 are fixedly connected to the hot riveting holes 203. The fixed connection of the hot riveting holes 203 ensures that the hot riveting head 201 will not loosen or shift during the hot riveting process. The upper template 4 has mounting and dismounting holes 204 around its upper perimeter. These holes are used to quickly connect and disconnect the upper template 4 from the external drive device, facilitating equipment installation, debugging, and maintenance. Multiple mounting and dismounting holes 204 penetrate the upper template 4, allowing connecting parts to pass through and achieving a secure connection between the upper template 4 and the drive device. The bottom mold 1 has multiple mold grooves 205 at its top. A mold slot 205 is used to place the product to be hot-riveted and to perform preliminary positioning of the product. The upper part of the bottom mold 1 and the bottom of the upper template 4 are provided with positioning components 206. The positioning components 206 further improve the alignment accuracy of the upper template 4 and the bottom mold 1 by cooperating with each other. Support seats 11 are fixedly connected around the bottom of the bottom mold 1. The support seats 11 are used to support the bottom mold 1 and keep the bottom mold 1 at a certain distance from the placement surface, which facilitates bottom operation and ventilation. Anti-slip pads 5 are fixedly connected to the bottom of multiple support seats 11. Anti-slip pads 5 can increase the friction between the support seats 11 and the placement surface, prevent the fixture from sliding during operation, and improve the stability of the equipment.

The position sensors 7 work together with the position sensors 6 to realize accurate detection and feedback of the movement position of the upper template 4, thereby controlling the movement stroke of the upper template 4 and ensuring the accuracy of the hot riveting action.

[0040] Specifically, the bottom mold 1 provides installation reference and support for each component. The upper batch hot riveting mechanism 2 enables simultaneous hot riveting of multiple products. The upper template 4 mounts and fixes the components of the batch hot riveting mechanism 2 and transmits driving force. The fixing mechanism 3 at the bottom of the upper template 4 firmly clamps the products within the mold groove 205 to prevent displacement. The fixing mechanism 3 is fixedly connected to the bottom mold 1 to ensure clamping stability. The positioning component 206 on the upper part of the bottom mold 1 ensures the relative positional accuracy of the upper template 4 and the bottom mold 1 during hot riveting. Multiple hot riveting heads 201 of the batch hot riveting mechanism 2 directly contact the product riveting posts to perform hot riveting. Multiple control units 202 on the rear side of the upper template 4 independently regulate whether the corresponding hot riveting heads 201 are working. Multiple hot riveting holes 203 inside the upper template 4 provide installation positioning references for the hot riveting heads 201.

The loading and unloading hole 204 penetrates the upper template 4, allowing the connecting parts to pass through for secure connection. Multiple mold slots 205 at the top of the bottom mold 1 place the product to be riveted and provide initial positioning. The positioning components 206 at the bottom of the bottom mold 1 and the bottom of the upper template 4 improve alignment accuracy through their cooperation. The support seats 11 around the bottom of the bottom mold 1 support the bottom mold 1 and maintain a distance from the placement surface, facilitating bottom operation and ventilation. The anti-slip pad 5 at the bottom of the support seat 11 increases the friction with the placement surface, preventing the fixture from sliding during operation and improving stability. The position sensor 6 on the front and rear sides of the top of the bottom mold 1 detects the real-time position information of the upper template 4. The position sensor 7 on the front and rear sides of the bottom of the upper template 4 cooperates with the position sensor 6 to achieve accurate detection and feedback of the movement position of the upper template 4, control the movement stroke, and ensure accurate riveting action.

[0041] Reference Figure 3 , Figure 4 and Figure 6The fixing mechanism 3 includes a hydraulic main pipe 301, which serves as the main transmission channel for hydraulic power, providing stable hydraulic energy to the entire fixing mechanism 3. The hydraulic main pipe 301 is fixedly connected to the upper rear side of the bottom mold 1. The fixed connection between the hydraulic main pipe 301 and the bottom mold 1 ensures the stability of its installation and prevents displacement during operation. Multiple hydraulic hoses 303 are fixedly connected to the front side of the hydraulic main pipe 301. The multiple hydraulic hoses 303 are used to transmit the hydraulic energy in the hydraulic main pipe 301 to each hydraulic actuator, realizing the distributed supply of power. Two-position two-way valves 302 are provided on the outside of each of the multiple hydraulic hoses 303. The two-position two-way valves 302 are used to control the on / off of the hydraulic oil in the corresponding hydraulic hoses 303, thereby realizing independent control of a single fixing unit. The front ends of each of the multiple hydraulic hoses 303 are slidably connected to hydraulic columns 304. The hydraulic columns 304 can perform linear reciprocating motion under the push of hydraulic oil, converting hydraulic energy into mechanical energy. The front ends of each of the multiple hydraulic columns 304 are fixedly connected to... A fixing block 306 is connected to the hydraulic column 304, which transmits power to the hydraulic column 304 and drives subsequent components to move synchronously. Each of the fixing blocks 306 has an L-shaped push plate 305 on its upper part. The L-shaped push plate 305 directly contacts the product, clamping and fixing it from the side and bottom through its L-shaped structure. Each of the fixing blocks 306 has a spring 308 on its front side. The spring 308 provides a restoring force when the hydraulic column 304 resets, driving the fixing blocks 306 and related components back to their initial position. Each of the mold grooves 205 has a sliding groove 307 on its upper part. The sliding groove 307 provides guidance for the movement of the fixed block 306, ensuring the accuracy of its movement trajectory. Each of the L-shaped push plates 305 has an L-shaped anti-slip pad 8 fixedly connected to its front side. The L-shaped anti-slip pad 8 can increase the friction between the product and the product, preventing the product from sliding during clamping and hot riveting. The L-shaped anti-slip pads 8 are all rounded. The rounding treatment can avoid the L-shaped anti-slip pads 8 from scratching the product surface and protect the product's appearance from damage.

[0042] Specifically, the hydraulic main pipe 301 provides stable hydraulic energy to the entire fixed mechanism 3. It is fixedly connected to the upper rear side of the bottom mold 1 to ensure installation stability and prevent displacement during operation. Multiple hydraulic hoses 303 on the front side of the hydraulic main pipe 301 transmit hydraulic energy to various hydraulic actuators, achieving distributed power supply. Two-position, two-way valves 302 outside the hydraulic hoses 303 control the flow of hydraulic oil within the corresponding hoses, enabling independent control of individual fixed units. The hydraulic column 304, slidably connected to the front end of the hydraulic hoses 303, performs linear reciprocating motion under the push of hydraulic oil, converting hydraulic energy into mechanical energy. The fixed block 306, fixedly connected to the hydraulic column 304, transmits the motion of the hydraulic column 304. The force drives the subsequent components to move synchronously. The L-shaped push plate 305 on the upper part of the fixing block 306 directly contacts the product. The L-shaped structure clamps and fixes the product from the side and bottom. The spring 308 on the front side of the fixing block 306 provides a rebound force when the hydraulic column 304 resets, driving the fixing block 306 and related components back to the initial position. The sliding groove 307 on the upper part of the mold groove 205 provides guidance for the movement of the fixing block 306, ensuring accurate movement trajectory. The L-shaped anti-slip pad 8 fixedly connected to the front side of the L-shaped push plate 305 increases the friction between the product and prevents the product from sliding during clamping and hot riveting. The smooth treatment of the L-shaped anti-slip pad 8 avoids scratching the product surface and protects the product appearance from damage.

[0043] Reference Figure 2 , Figure 3 and Figure 6The positioning component 206 includes multiple positioning posts 2061. These positioning posts 2061 are core guiding components for achieving precise alignment between the upper template 4 and the bottom mold 1. The multiple positioning posts 2061 are fixedly connected to the front and rear sides of the bottom of the upper template 4. This fixed connection ensures the positioning accuracy and stability of the positioning posts 2061 as they move synchronously with the upper template 4. The upper front and rear sides of the bottom mold 1 are provided with multiple positioning holes 2062. These holes provide insertion space and a mating reference for the positioning posts 2061. Multiple positioning posts 2061 are slidably connected to the top of the multiple positioning holes 2062. The sliding fit between the positioning posts 2061 and the positioning holes 2062 achieves precise alignment between the upper template 4 and the bottom mold 1 during the hot riveting process. To prevent displacement, multiple fixing blocks 306 are each fixedly connected with sliding rod beads 9. The sliding rod beads 9 are used to reduce the frictional resistance between the fixing blocks 306 and the sliding grooves 307. The sliding rod beads 9 are all slidably connected to the sliding grooves 307. The sliding connection between the sliding rod beads 9 and the sliding grooves 307 makes the movement of the fixing blocks 306 smoother and more stable, ensuring the accuracy of the clamping action. The bottom of the upper template 4 is fixedly connected with a sealing ring 10. The sealing ring 10 is used to form a sealed space when the upper template 4 and the bottom mold 1 are closed, preventing foreign objects from entering or excessive heat loss during the hot riveting process. The top of the bottom mold 1 is fixedly connected with a buffer ring 12. The buffer ring 12 can play a buffering role when the upper template 4 moves down and contacts the bottom mold 1, reducing the impact force of the collision.

[0044] Specifically, the multiple positioning posts 2061 of the positioning component 206 are the core guiding components for achieving precise alignment between the upper template 4 and the bottom mold 1. They are fixedly connected to the front and rear sides of the bottom of the upper template 4 to ensure positional accuracy and stability during synchronous movement with the upper template 4. The multiple positioning holes 2062 on the front and rear sides of the upper part of the bottom mold 1 provide insertion space and mating reference for the positioning posts 2061. The top of the positioning holes 2062 is slidably connected to the positioning posts 2061 to achieve precise positioning of the upper template 4 and the bottom mold 1 during the hot riveting process and prevent displacement. The sliding rod bead 9 inside the fixed block 306 reduces the frictional resistance between the fixed block 306 and the sliding groove 307. The sliding rod bead 9 and the sliding groove 307 are slidably connected, making the movement of the fixed block 306 smoother and more stable, ensuring the accuracy of the clamping action. The sealing ring 10 at the bottom of the upper template 4 forms a sealed space when the upper template 4 and the bottom mold 1 are closed, preventing foreign objects from entering or excessive heat loss during the hot riveting process. The buffer ring 12 at the top of the bottom mold 1 plays a buffering role when the upper template 4 moves down and contacts the bottom mold 1, reducing the impact force of the collision.

[0045] Working principle: First, the upper mold is assembled, and multiple hot riveting heads 201 are embedded into the hot riveting holes 203 of the upper mold to form a multi-station hot riveting array. Then, the upper mold is fixed to the driver through the loading and unloading holes 204, so that the drive mechanism can synchronously drive all the hot riveting heads 201 to move precisely. The control unit 202 pre-stores multiple sets of hot riveting parameters and can independently control each hot riveting head 201. The anti-slip pad 5 enhances the stability of the bottom mold 1 and avoids positioning deviation caused by vibration during operation. The mold groove 205 of the bottom mold 1 adopts a multi-groove parallel design, which can simultaneously place multiple products to be hot riveted. Each groove corresponds to the upper mold. A hot riveting head 201 forms a one-to-one corresponding processing unit. The upper mold moves downward under the drive mechanism. The positioning post 2061 and the positioning hole 2062 are precisely engaged, providing a unified benchmark for the hot riveting points of all products. Multiple hot riveting heads 201 simultaneously contact the riveting post of the corresponding product. The control unit 202 starts heating and pressurizing according to preset parameters to realize the simultaneous hot riveting of multiple products. After the hot riveting is completed, the upper mold is reset and multiple processed products are taken out. This solves the efficiency problem of only being able to process a single product at a time in the existing technology. The precise positioning structure ensures the quality consistency of simultaneous processing of multiple products.

[0046] Furthermore, after multiple products are placed into the mold slots 205, the system initiates the hydraulic control process. The hydraulic main pipe 301 acts as a power source, delivering hydraulic energy, which is precisely distributed to the hydraulic hoses 303 at the corresponding workstations via the fixing mechanism 3. Single or multiple mold slots 205 can be flexibly selected for use according to production needs. For the selected mold slot 205, the hydraulic hoses 303 deliver high-pressure liquid to the hydraulic column 304, pushing it forward axially. The thrust of the hydraulic column 304 is transmitted to the fixing block 306, causing the fixing block 306 to move the sliding rod ball 9 within the sliding groove 307. Smooth sliding, the L-shaped push plate 305 moves synchronously with the fixed block 306 until the L-shaped anti-slip pad 8 is in contact with the product surface. The product is clamped from multiple directions by the symmetrically distributed L-shaped push plates 305. After the hot riveting operation is completed, the control system issues a command to shut off the liquid delivery of the hydraulic hose 303, and the pressure of the hydraulic column 304 is released. At this time, the rebound force of the spring 308 pushes the fixed block 306 to reset in the opposite direction along the sliding groove 307, which drives the L-shaped push plate 305 to detach from the product, making it easier to remove the product. This breaks through the limitation of traditional single-station operation of fixtures and significantly improves the efficiency of mass production.
