Description

Technical Field

[0001] This utility model relates to the field of riveting technology, specifically to a multi-point automatic riveting device for housings. Background Technology

[0002] In modern manufacturing, the assembly of housings typically requires riveting. Traditional riveting methods rely mainly on manual labor or simple mechanical equipment, which significantly limits production efficiency and riveting quality. Manual riveting is labor-intensive and inefficient, and due to variations in operator skill levels and physical condition, the riveting quality is inconsistent, making it difficult to guarantee product consistency and reliability. Furthermore, for complex shapes or large housings, manual operation struggles to precisely rivet multiple points, easily leading to inaccurate rivet placement and uneven riveting strength, severely impacting product performance and lifespan.

[0003] While some existing simple automatic riveting equipment has improved production efficiency to some extent, it still has many shortcomings. It often operates only on a single or limited number of riveting points. For shells requiring multi-point riveting, it cannot achieve efficient and precise riveting, necessitating multiple adjustments to the shell's position or equipment replacements, increasing operational complexity and time costs. Furthermore, when performing multiple riveting operations, it is difficult to guarantee the positional accuracy and consistency of riveting parameters between different riveting points, leading to unstable product quality. Simultaneously, some automatic riveting equipment is not perfect in terms of shell positioning and fixation. During the riveting process, due to the lack of effective positioning measures, the shell is prone to displacement, affecting the accuracy and quality of the riveting and resulting in a higher number of defective products.

[0004] Furthermore, existing automatic riveting equipment suffers from inflexible structural design, exhibiting poor adaptability to housings of varying sizes and shapes. This necessitates frequent component replacements or structural adjustments, increasing production preparation time and costs. Moreover, maintenance and upkeep costs are high. Due to the non-standardized design and complex structure of its components, repairs are difficult in the event of a malfunction, impacting production continuity. Additionally, when facing high-precision riveting requirements, existing equipment often fails to effectively address hole position deviations on the housing and cannot automatically adjust the riveting position, thus failing to meet the production demands of products requiring high riveting accuracy.

[0005] Therefore, in order to overcome the above problems and meet the modern manufacturing industry's demand for efficient, precise, stable, automated and intelligent riveting, it is necessary to develop a new type of multi-point automatic riveting device for housings. This device would improve the production efficiency, quality and adaptability of housing riveting, reduce labor intensity, ensure product consistency and reliability, and facilitate easy maintenance and upkeep of the equipment.

[0051] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0052] like Figures 1-4As shown, this utility model proposes a multi-point automatic riveting device for housings, comprising: a frame 1; a housing placement platform 2 disposed on the frame 1 for placing housings; a riveting assembly 3 disposed on the frame 1, located on one side of the housing placement platform 2, for riveting the housings, the riveting assembly 3 including a mounting bracket 31 and a riveting gun 32, the mounting bracket 31 being slidably disposed on the frame 1, and at least two mounting brackets 31 being arranged side by side; a riveting gun 32 being slidably and vertically disposed on the mounting bracket 31, the riveting gun 32 being located above the housing placement platform 2; the sliding direction of the mounting bracket 31 is the X-axis direction, the sliding direction of the riveting gun 32 is the Y-axis direction, and the vertical direction of the riveting gun 32 is the Z-axis direction.

[0053] In this embodiment, the frame 1 provides the support structure for the entire device; the housing placement platform 2 provides a placement position for the housing to be riveted, ensuring the relative stability of the housing during riveting operations; the riveting assembly 3 is the core part of the device, installed on the frame 1 and located on one side of the housing placement platform 2. It has at least two parallel mounting brackets 31, and the rivet gun 32 slides and rises and falls on the mounting brackets 31, enabling riveting operations on the housing at different positions and heights. The rivet gun 32 has three-dimensional motion freedom in space: the X-axis (mounting bracket sliding direction), the Y-axis (rivet gun sliding direction), and the Z-axis (rivet gun rising and falling direction), making multi-point riveting possible. This allows the device to perform riveting operations on different points on the housing from multiple angles and positions, improving the flexibility and coverage of riveting, and laying the foundation for subsequent automated multi-point riveting operations.

[0054] The arrangement of multiple mounting brackets 31 and rivet guns 32 on them allows for simultaneous riveting operations at multiple stations during the riveting process of the housing, greatly improving efficiency. Furthermore, if a rivet gun 32 malfunctions, the overall riveting operation will not be affected, thus enhancing the stability and reliability of the overall processing.

[0055] Furthermore, the riveting assembly 3 also includes a guide rail 33, which is mounted on the frame 1. There are two guide rails 33 arranged in parallel, and the housing placement platform 2 is located between the two guide rails 33. The mounting bracket 31 has two ends, and the two ends of the mounting bracket 31 slide on the two guide rails 33 respectively.

[0056] In this embodiment, refer to Figure 1As shown, two parallel guide rails 33 are set on the frame 1, and the housing platform 2 is placed between them, so that the two ends of the mounting bracket 31 slide on the two guide rails 33 respectively. This enhances the stability and guidance of the sliding of the mounting bracket 31, ensures that the rivet gun 32 moves more smoothly and accurately in the X-axis direction, avoids the rivet gun 32 from deviating during operation, and thus improves the accuracy and reliability of riveting. This helps to ensure the overall performance and service life of the riveting assembly 3 in long-term use and operation, and plays an important auxiliary role in realizing accurate multi-point riveting operation.

[0057] In addition, multiple mounting brackets 31 share a single guide rail 33, which improves the efficiency of riveting operations, reduces the complexity of installation, and makes the overall design simpler. Furthermore, sharing the guide rail 33 reduces the installation and usage costs of the guide rail 33 and facilitates maintenance and upkeep.

[0058] Furthermore, the frame 1 has a riveting station 11 and a loading station 12. The riveting station 11 is located below the riveting assembly 3, and the loading station 12 is located on one side of the riveting station 11. The housing placement platform 2 includes a support 21, which is movably mounted on the frame 1. The support 21 is used to place the housing, and after moving, the support 21 is located at the riveting station 11 or the loading station 12.

[0059] In this embodiment, refer to Figure 1 As shown, a riveting station 11 and a loading station 12 are set on the frame 1. The riveting station 11 is placed below the riveting assembly 3, and the loading station 12 is on one side of the riveting station 11. Simultaneously, the support piece 21 can move on the frame 1, allowing it to switch positions between the riveting station 11 and the loading station 12, thus streamlining the riveting operation. The loading station facilitates the operator placing the shell to be riveted onto the support piece 21, and then moving the support piece 21 to the riveting station 11 for the riveting operation. This makes the entire device operation more orderly, improves the automation level and work efficiency, reduces interference between different processes, facilitates operator operation, and also benefits subsequent automated control and management.

[0060] Furthermore, the support component 21 includes a first support plate 22 and a second support plate 23 that are movable. The first support plate 22 and the second support plate 23 are located at the riveting station 11 and the loading station 12, respectively. The positions of the first support plate 22 and the second support plate 23 are interchanged after they are moved.

[0061] In this embodiment, the support 21 is divided into a first support plate 22 and a second support plate 23, which are located at the riveting station 11 and the loading station 12, respectively. Their positions can be interchanged by movement, meaning that while one support plate is undergoing riveting, the other support plate can simultaneously perform loading, enabling parallel operation. This design further improves the device's efficiency, reduces downtime, and makes the entire workflow more compact, fully utilizing time and space, thus increasing the device's production cycle time. It is particularly suitable for large-scale production scenarios, improving overall production efficiency.

[0062] Furthermore, both the first pallet 22 and the second pallet 23 are slidably and vertically mounted on the frame 1. After the first pallet 22 is raised, a channel 24 is formed below it. The channel 24 is used to allow the second pallet 23 to pass through. After the first pallet 22 slides, it is located at the riveting station 11 or the loading station 12. After the second pallet 23 slides, it is located at the riveting station 11 or the loading station 12.

[0063] In this embodiment, both the first pallet 22 and the second pallet 23 are slidably and vertically mounted on the frame 1. After the first pallet 22 is raised, a channel 24 is formed below it, allowing the second pallet 23 to pass through. Through the combination of lifting and sliding actions, it is ensured that the pallets can quickly and accurately switch between different workstations in complex production environments, avoiding collisions and interference, and improving the reliability and stability of the device.

[0064] Furthermore, the support member 21 also includes a first slider 25, a first telescopic support member 26, a second slider 27, and a second telescopic support member 28. The first slider 25 is slidably disposed on the frame 1, and after sliding, the first slider 25 is located at the riveting station 11 or the loading station 12. The first telescopic support member 26 is disposed on the first slider 25, and the first support plate 22 is disposed on the first telescopic support member 26. After the first telescopic support member 26 extends or retracts, the first support plate 22 rises or falls. The second slider 27 is slidably disposed on the frame 1, and after sliding, the second slider 27 is located at the riveting station 11 or the loading station 12. The second telescopic support member 28 is disposed on the second slider 27, and the second support plate 23 is disposed on the second telescopic support member 28. After the second telescopic support member 28 extends or retracts, the second support plate 23 rises or falls.

[0065] In this embodiment, refer to Figure 2As shown, by setting the first slider 25, the first telescopic support 26, the second slider 27, and the second telescopic support 28, the specific driving and support structures of the first pallet 22 and the second pallet 23 are clarified. The slider allows the pallet to slide on the frame 1, and the telescopic support enables the pallet to be raised and lowered. The telescopic supports 26 and 28 can be pneumatic or electric cylinders, providing a clear power source and driving method, making the movement of the pallet more precise and controllable. It also facilitates the adjustment of the pallet's movement speed, position, and force, which is beneficial for achieving automated control, improving the automation level and accuracy of the device, and ensuring stable movement and precise position adjustment of the pallet.

[0066] Furthermore, the first telescopic support 26 and the second telescopic support 28 are either pneumatic cylinders or electric cylinders.

[0067] In this embodiment, the first telescopic support 26 and the second telescopic support 28 are designated as pneumatic cylinders or electric cylinders, making the selection of these components clearer and facilitating the manufacturing, maintenance, and repair of the device. Because pneumatic cylinders and electric cylinders have standardized interfaces and stable performance, and are also easy to automate, they can provide sufficient driving force as needed to ensure accurate, stable, and reliable lifting and lowering of the first pallet 22 and the second pallet 23. This reduces malfunctions and errors caused by unstable power sources, improving the overall performance and reliability of the device.

[0068] Furthermore, it also includes a positioning and pressing component 4. The positioning and pressing component 4 is provided on both the first support plate 22 and the second support plate 23. The positioning and pressing component 4 is used to fix the position of the housing.

[0069] In this embodiment, positioning pressure members 4 are provided on the first pallet 22 and the second pallet 23 to fix the position of the housing placed on the pallet, preventing the housing from shifting during the riveting process, ensuring the accuracy and quality of riveting, and avoiding the deviation of the riveting position caused by the movement of the housing. This is of great significance for ensuring the consistency and accuracy of riveting, ensuring that each rivet point can be riveted according to the predetermined position and parameters, reducing the defective products caused by inaccurate housing position, and improving the quality and pass rate of the product.

[0070] Furthermore, the positioning and pressing component 4 includes a telescopic component 41, which is provided on both the first support plate 22 and the second support plate 23; the pressing block 42 is provided on the telescopic component 41, and the pressing block 42 has a lower pressing surface 43, which has a gap with the surface of the first support plate 22 or the surface of the second support plate 23.

[0071] In this embodiment, the combination of the telescopic member 41 and the pressure block 42 can effectively position and press the housing. The telescopic member 41 can control the downward pressing action of the pressure block 42. The gap between the pressing surface 43 and the pallet surface ensures that it will not interfere with the operation on the pallet when not in use, and can press down to fix the housing when needed. Multiple positioning and pressing members 4 can fix the housing from multiple positions, restricting the housing's degrees of freedom from different directions, further enhancing the positioning effect of the housing, enabling the housing to maintain high stability during riveting, improving riveting accuracy, ensuring the stability and reliability of the riveting operation, thereby improving the quality and consistency of the product.

[0072] Furthermore, the positioning pressure component 4 also includes a buffer pad 44, which is disposed on the lower pressure surface 43.

[0073] In this embodiment, a buffer pad 44 is provided on the pressing surface 43, which can play a buffering and protective role when the pressing block 42 presses down to fix the shell, avoiding damage to the shell surface caused by the pressing block 42. Especially for some shells with high requirements for appearance and surface quality, it prevents scratches or indentations caused by the direct pressing of the pressing block, ensuring the appearance quality of the product. At the same time, it may also extend the service life of the shell to a certain extent, improving the overall quality and aesthetics of the product.

[0074] Furthermore, both the first pallet 22 and the second pallet 23 have several positioning and pressing components 4.

[0075] In this embodiment, refer to Figure 4 As shown, several positioning and pressing parts 4 are provided on both the first tray 22 and the second tray 23 to fix the shell from more points, forming a multi-point positioning and fixing effect. This makes the shell more firmly and stably fixed on the tray, further preventing the shell from moving and rotating during the riveting process. This improves the accuracy and stability of the riveting operation and helps to ensure the consistency of product quality. In particular, for shells with larger size or complex shape, it can better adapt to the fixing needs of different positions and reduce riveting problems caused by local insecure fixing.

[0076] Furthermore, it also includes a hole position detection and positioning camera, which is set next to the rivet gun 32. The hole position detection and positioning camera is used to determine the hole position on the housing. Based on the determined hole position, the position of the rivet gun 32 is adjusted, thereby improving the accuracy and precision of riveting and enhancing the quality of riveting.

[0077] In this embodiment, the hole position detection and positioning camera located next to the rivet gun 32 can determine the hole positions on the housing before the riveting operation. Based on the hole position information, the position of the rivet gun 32 is fine-tuned, thereby improving the accuracy and precision of the riveting and enhancing the riveting quality. This design enables the device to possess intelligent detection and adaptive adjustment capabilities. When faced with potential deviations in the hole positions on the housing, it can automatically adjust the position of the rivet gun 32 to ensure accurate alignment with the hole positions, avoiding riveting failures or quality degradation due to hole position errors. This improves the device's adaptability to different housing hole position deviations, enhances the intelligence level of the riveting operation, and further guarantees product quality and yield. It is particularly suitable for products and production scenarios with high riveting precision requirements.
