Description

Technical Field

[0001] This invention relates to the technical field of parts placement, and more particularly to an adaptive parts placement stage and placement method. Background Technology

[0002] In the automotive manufacturing industry, with the continuous improvement of automation and intelligence levels, production lines are facing increasingly stringent requirements for processing efficiency and reliability. The manufacturing and assembly of automotive parts typically involves multiple continuous or parallel processes, such as cutting, welding, inspection, and assembly. During this process, the parts to be processed need to move between different workstations and undergo various operations.

[0003] like Figure 1 , Figure 2 As shown, the core structural logic of the existing parts placement platform is a one-to-one correspondence between support base 2, pneumatic cylinder 4, and support head 3. Support base 2 is installed on base 1. The root of its defect lies in the fact that the design of support head 3 is strongly bound to the part's profile. Support head 3 is made of nylon material and needs to be CNC machined according to the specific part's profile, meaning one set of customized support head 3 corresponds to one part. Each support base 2 can install multiple pneumatic cylinders 4, and each pneumatic cylinder 4 is matched with only one customized support head 3. Ultimately, the entire placement platform can only be compatible with a maximum of 4 types of parts. When the production demand exceeds 4 types of parts, new support heads 3 need to be redesigned and machined, and the original assembly structure of pneumatic cylinder 4 and support head 3 needs to be disassembled and replaced with new adapter components. This process not only requires additional material costs (customized nylon support heads 3) but also requires equipment downtime, leading to a decrease in production efficiency and failing to meet the core requirements of flexible manufacturing for multiple varieties and small batches. Moreover, nylon material has high hardness, and during placement, the rigid contact between support head 3 and part surface can easily cause scratches and indentations, leading to an increased part scrap rate. Because the support head 3 needs to be customized according to the part profile, the size and shape of different support heads 3 vary greatly. During assembly, it is necessary to strictly correspond to the position of the pneumatic cylinder 4, which increases the risk of assembly error. In subsequent maintenance, if a single support head 3 is damaged, a replacement part needs to be customized separately, which is not universal, resulting in long maintenance cycle and high cost.

[0004] To address the aforementioned issues, existing technologies urgently need improvement. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an adaptive parts placement stage and placement method to overcome the shortcomings of existing parts placement stages in terms of limited compatibility and low adaptation efficiency, thereby improving production efficiency and product quality, and fully meeting the core requirements of flexibility and low cost in modern intelligent manufacturing.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: An adaptive parts placement platform includes an assembly frame mounted on the ground or a workbench, with multiple vertical adaptive components evenly mounted on the assembly frame. Each vertical adaptive component has a support block mounted on its upper end. Parts are placed above the assembly frame and supported by the multiple support blocks.

[0007] A further technical solution is that the vertical adaptive component includes a vertical cylinder, the cylinder body of which is detachably mounted on the assembly frame, the upper end of the cylinder rod of the vertical cylinder is coaxially connected to the support block, and each vertical cylinder is connected to the interconnected air pipeline network.

[0008] A further technical solution is that a lower air guide hole group and an upper air guide hole group are provided on the cylinder body of the vertical cylinder. The lower air guide hole group is constructed at the lower end of the cylinder body, and the upper air guide hole group is constructed at the upper end of the cylinder body. Both the lower air guide hole group and the upper air guide hole group are connected to the interconnected air pipeline network.

[0009] A further technical solution is that the lower air guide hole group includes a plurality of lower air guide holes evenly arranged along the circumference of the cylinder body, and the upper air guide hole group includes a plurality of upper air guide holes evenly arranged along the circumference of the cylinder body, and each lower air guide hole and each upper air guide hole are connected to the interconnected air pipeline network.

[0010] A further technical solution is that the interconnected air pipe network includes multiple lower air pipes and multiple upper air pipes. The multiple lower air pipes are connected to the lower air guide hole groups of multiple vertical cylinders, and form a lower network shape with each vertical cylinder as the intersection point. The multiple upper air pipes are connected to the upper air guide hole groups of multiple vertical cylinders, and form a network shape with each vertical cylinder as the intersection point.

[0011] A further technical solution involves installing a pressure sensor on the interconnected gas pipeline and connecting an automatic adjustment device to the interconnected gas pipeline.

[0012] A further technical solution is that the support block is a structure made of polyurethane material.

[0013] A further technical solution is that the assembly frame includes a rectangular frame body, and adjustable fixing feet are installed at the four corners of the frame body.

[0014] A further technical solution is that the adjustable fixing foot includes a connecting ear fixed to the bottom corner of the frame body, a vertical adjustment screw threaded onto the connecting ear, a support foot installed at the lower end of the vertical adjustment screw, an angle plate installed on the ground or workbench at each connecting ear, and a strip hole extending vertically is opened in the vertical part of the angle plate, and a connecting bolt passes through the strip hole and connects to the connecting ear.

[0015] The present invention also discloses an adaptive part placement method, which applies the above-mentioned adaptive part placement stage and includes the following steps: Step 1. Introduce a predetermined amount of gas into the interconnected gas pipeline network so that the pistons of each vertical cylinder are in the middle position and all support blocks are in the position of half of their maximum stroke. This is the initial state of the adaptive parts placement stage. Step 2. Place the parts onto the adaptive part placement stage manually or by robot. The support blocks on the adaptive part placement stage are pressed and, depending on the different gravity they are subjected to, and with the gas being conducted through the interconnected gas pipeline, the support blocks automatically move down or up to the predetermined position with the cylinder rod to match the shape of the parts. Step 3. After the parts are removed manually or by a robot, the support blocks on the adaptive part placement platform will automatically return to their initial positions as the pressure is released. Step 4. Repeat steps 2 and 3 to place different types of parts.

[0016] The beneficial effects of adopting the above technical solution are as follows: The vertical adaptive components in the adaptive part placement stage of this invention can adapt to the shape of the part. When a part is placed on multiple vertical adaptive components, the support blocks on these vertical adaptive components are displaced vertically under the gravity of the part, so that the support blocks in contact with the part are shaped to conform to the part. After the part leaves the adaptive part placement stage, each vertical adaptive component will automatically return to its original position for the next placement operation.

[0017] This invention completely breaks through the existing technology's limit of being compatible with a maximum of four types of parts. Through a pressure adaptive mechanism, it can adapt to parts of any shape and weight (such as automotive body stampings, electronic device housings, mechanical transmission gears, etc.) without replacing support blocks or adjusting cylinder structures. For multi-product manufacturing enterprises (such as automotive parts suppliers and electronic device contract manufacturers), it can reduce the number of placement platforms, thereby lowering equipment procurement costs; at the same time, it reduces the equipment footprint and optimizes the workshop layout.

[0018] In summary, this invention effectively solves the shortcomings of existing parts placement platforms, such as limited compatibility and low adaptation efficiency, thereby improving production efficiency and product quality, and fully meeting the core requirements of flexibility and low cost in modern intelligent manufacturing.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] In the description of this invention, unless otherwise stated, the terms "upper," "lower," "left," "right," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0024] Example 1 An adaptive parts placement stage, such as Figures 3-6 As shown, the assembly includes an assembly frame 100 and multiple vertical adaptive components 200. The assembly frame 100 is mounted on the ground or a workbench, and the multiple vertical adaptive components 200 are evenly mounted on the assembly frame 100. A support block 300 is mounted on the upper end of each vertical adaptive component 200. The parts are placed above the assembly frame 100 and supported by the multiple support blocks 300.

[0025] The vertical adaptive components 200 in the adaptive part placement table of this invention can adapt to the shape of the parts. When a part is placed on multiple vertical adaptive components 200, the support blocks 300 on these components 200 are vertically displaced under the weight of the part, causing the support blocks 300 in contact with the part to conform to the shape of the part. Furthermore, after the part leaves the adaptive part placement table, each vertical adaptive component 200 automatically returns to its original position for the next placement operation. This invention completely breaks the existing technology's limit of a maximum of four types of parts. Through a pressure adaptive mechanism, it can adapt to parts of any shape and weight (such as automotive body stampings, electronic device housings, mechanical transmission gears, etc.) without replacing the support blocks 300 or adjusting the cylinder structure. For multi-product manufacturing enterprises (such as automotive parts suppliers and electronic device manufacturers), it can reduce the number of placement tables, lowering equipment procurement costs; simultaneously, it reduces the equipment footprint and optimizes the workshop layout.

[0026] In summary, this invention effectively solves the shortcomings of existing parts placement platforms, such as limited compatibility and low adaptation efficiency, thereby improving production efficiency and product quality, and fully meeting the core requirements of flexibility and low cost in modern intelligent manufacturing.

[0027] Example 2 like Figure 3 , Figure 4 , Figure 6 As shown, the vertical adaptive component 200 includes a vertical cylinder with a fixing lug 203 at its lower end, which is detachably connected to the upper end of the assembly frame 100. A support block 300 is coaxially mounted on the upper end of the vertical cylinder rod 202, and each vertical cylinder is connected to the interconnected air network 400. In this embodiment, each vertical cylinder has a lower air guide hole group and an upper air guide hole group on its cylinder body 201, with the piston inside the cylinder body 201 located between the lower and upper air guide hole groups. The lower air guide hole group is located at the lower end of the cylinder body 201, and the upper air guide hole group is located at the upper end of the cylinder body 201, both of which are connected to the interconnected air network 400. The lower air guide hole group includes a plurality of lower air guide holes evenly arranged along the circumference of the cylinder block 201, and the upper air guide hole group includes a plurality of upper air guide holes evenly arranged along the circumference of the cylinder block 201. Each lower air guide hole and each upper air guide hole are connected to the interconnected air pipeline network 400.

[0028] The interconnected air network 400 of this embodiment includes multiple lower air pipes 401 and multiple upper air pipes 402. These lower air pipes 401 connect to the lower air guide port groups of multiple vertical cylinders, forming a lower mesh shape with each vertical cylinder as an intersection point. This lower mesh shape connects the chambers (lower chambers) of each vertical cylinder located below the piston. The aforementioned multiple upper air pipes 402 connect to the upper air guide port groups of multiple vertical cylinders, forming a net shape with each vertical cylinder as an intersection point. This net shape connects the chambers (upper chambers) of each vertical cylinder located above the piston.

[0029] When a part is placed on a support block 300, the difference in gravity experienced by different support blocks 300 is converted into pressure changes within the vertical cylinder. The pressure is transmitted in real time through the interconnected air network 400, enabling the pistons of all vertical cylinders to adjust their positions in tandem. Instead of customizing support blocks 300 for specific parts, the pressure adaptively matches the profile of any part, fundamentally solving the limitation of one set of support blocks 300 for one type of part and achieving the goal of unlimited compatibility with a number of parts.

[0030] Example 3 like Figure 6 As shown, the support block 300 is a structure made of polyurethane material, which can be in various shapes such as cylindrical or cubic. Generally, when selecting the shape of the support block 300, it is ensured that the shape is consistent. This ensures that, on the one hand, the polyurethane material has a lower hardness than nylon and possesses a certain degree of elasticity, preventing damage to the surface of the parts; on the other hand, the standardized design eliminates the need for customization of the support block 300, eliminates the need to distinguish its position during assembly, and allows for direct replacement of common parts after damage. This solves the problems of difficult assembly and expensive maintenance of non-standardized support blocks 300 in existing technologies.

[0031] Example 4 like Figure 5 As shown, the assembly frame 100 includes a rectangular frame body 101, with adjustable fixing feet installed at each of the four corners of the frame body 101. Each adjustable fixing foot includes a connecting lug 102, a vertical adjustment screw 103, a support foot 104, and a corner plate 105. The connecting lug 102 is fixed to the bottom corner of the frame body 101. The vertical adjustment screw 103 is threaded onto the connecting lug 102 and locked in place by a locking nut threaded onto it. The support foot 104 is installed at the lower end of the vertical adjustment screw 103. In this embodiment, the corner plate 105 is installed on the ground or a workbench, and is correspondingly positioned to the connecting lug 102. A strip-shaped hole 106 is provided in the vertical portion of the corner plate 105, extending vertically. A connecting bolt passes through the strip-shaped hole 106 and connects to the connecting lug 102.

[0032] When the vertical adjusting screw 103 is rotated, the screw can move vertically along the threaded hole of the connecting lug 102. When rotated clockwise, the vertical adjusting screw 103 extends downward, causing the lower support foot 104 to move downward synchronously. When rotated counterclockwise, the vertical adjusting screw 103 retracts upward, and the support foot 104 moves upward synchronously, thereby changing the height of a certain corner of the assembly frame 100. That is, for uneven areas of the ground / workbench, the vertical adjusting screw 103 of the corresponding corner can be raised or lowered individually to keep the table surface of the assembly frame 100 always horizontal.

[0033] For example, when a corner of the ground is lower than other areas, rotating the vertical adjustment screw 103 of that corner clockwise will lower the support foot 104 to be in contact with the ground, ensuring that all four corners of the assembly frame 100 are stably stressed and preventing the initial position deviation of the support block 300 due to the tilt of the assembly frame 100. If the height of the assembly frame 100 needs to be adjusted during production (such as to adapt to the operation of robots of different heights or to change the worktable), simply loosen the locking nut and connecting bolt and rotate the vertical adjustment screw 103 to complete the height adjustment. There is no need to disassemble the entire adjustable fixed foot or the assembly frame 100, which greatly shortens the maintenance time.

[0034] For example, when the production line replaces parts with higher specifications, and the height of the adaptive parts placement platform needs to be increased to match the robot's gripping position, the height of the four adjustable fixed feet can be quickly adjusted without redesigning or replacing the main structure of the adaptive parts placement platform. That is, all the vertical adjustment screws 103 are rotated synchronously and in the same direction, and the overall height of the frame body 101 is adjusted.

[0035] Angle plate 105 is fixed to the ground / workbench, and its vertical section has a strip-shaped hole 106 extending vertically. Since height adjustment causes vertical displacement of the connecting lug 102 (along with the frame body 101), the vertical extension design of the strip-shaped hole 106 accommodates changes in the position of the connecting lug 102 during adjustment. Regardless of the vertical position of the connecting lug 102 due to height adjustment, the connecting bolt can pass through the strip-shaped hole 106 and connect to the connecting lug 102, preventing misalignment of the fixing hole due to height adjustment. After the connecting bolt passes through the strip-shaped hole 106 and is threaded onto the connecting lug 102, tightening the connecting bolt will securely fix the connecting lug 102 to the angle plate 105. The fixing of the corner plate 105 to the ground / workbench and the fixing of the connecting ear 102 to the frame body 101 form a rigid force transmission path of "ground-corner plate 105-connecting ear 102-frame body 101" through connecting bolts, which transmits the weight of the assembly frame 100 and the load when the parts are placed to the ground / workbench, thus preventing the assembly frame 100 from shaking or shifting during use.

[0036] Therefore, it can be seen that the adjustable fixing feet solve the problem of 100-degree horizontal alignment of the assembly frame through precise height adjustment, ensure the stability of use through rigid fixing, and reduce the limitation of the scene through flexible adaptation. It fundamentally makes up for the defects of traditional fixing feet, such as non-adjustability, poor adaptability and weak stability, and provides key support for the overall reliability of the adaptive parts placement stage.

[0037] Example 5 In this embodiment, pressure sensors are installed on the interconnected air pipeline network 400, and an automatic adjustment device is connected to the interconnected air pipeline network 400. Specifically, a pressure sensor is installed on one of the lower-level air pipelines 401, and another pressure sensor is installed on one of the upper-level air pipelines 402. Two automatic adjustment devices are provided, each connected to one lower-level air pipeline 401 and one upper-level air pipeline 402 respectively. The automatic adjustment device includes a solenoid directional valve and a flow control valve. The outlet of the solenoid directional valve is connected to the inlet of the flow control valve, and the outlet of the flow control valve is connected to the corresponding upper-level air pipeline 402 or lower-level air pipeline 401. The inlet of the solenoid directional valve is connected to an external air source (pressure tank or air compressor).

[0038] The gas output from the external gas source is first controlled by an electromagnetic reversing valve, then its flow rate is regulated by a flow control valve, and finally stably input into the interconnected gas pipeline 400. This prevents the piston of the vertical cylinder from rising and falling suddenly due to excessively high gas flow rate, which could disrupt the balance of the support block 300. In this embodiment, when the pressure sensor detects an abnormal pressure in a certain circuit (such as the upper circuit), the electromagnetic reversing valve and flow control valve of the corresponding circuit can operate independently, adjusting the intake / exhaust only for that circuit. This avoids affecting the pressure balance of the other circuit, thereby ensuring the accuracy of the support block 300's position adjustment.

[0039] Example 6 An adaptive part placement method, using the aforementioned adaptive part placement stage, includes the following steps: Step 1. Introduce a predetermined amount of gas into the interconnected gas pipeline 400 so that the pistons of each vertical cylinder are in the middle position and all support blocks 300 are in the position of half of their maximum stroke. This is the initial state of the adaptive parts placement stage. Step 2. Place the parts onto the adaptive part placement stage manually or by robot. The support block 300 on the adaptive part placement stage is pressed and, depending on the different gravity, and with the gas being conducted through the interconnected air network 400, the support block 300 automatically moves down or up to the predetermined position with the cylinder rod 202 to match the shape of the part. Step 3. After the parts are removed manually or by a robot, the support block 300 on the adaptive part placement platform loses pressure and automatically returns to its initial position; Step 4. Repeat steps 2 and 3 to place different types of parts.

[0040] This invention, through the synergistic effect of a metered gas supply and an interconnected gas pipeline network 400, ensures that the initial height of all support blocks 300 is completely uniform. The interconnected gas pipeline network 400 ensures uniform pressure transmission within each vertical cylinder, and the metered gas supply precisely controls the piston stroke, avoiding initial positional deviations caused by vertical cylinder assembly errors, gas pipeline leaks, or other factors. This provides a standardized reference surface for subsequent component adaptation. Moreover, there is no need for manual adjustment of the height of each support block 300; the initial positioning of all support blocks 300 can be completed with a single metered gas supply, significantly shortening the debugging time before the adaptive component placement platform is put into use.

[0041] This method uses dynamic adaptation based on gravity, pressure, and displacement to adapt to parts of any shape and weight without replacing any components. For example, when placing an automotive stamping part (irregular curved surface), the support block 300 in the protruding area of ​​the part is under greater pressure and moves downward with the cylinder rod 202; the support block 300 in the recessed area is under less pressure and moves upward under the pressure transmission of the interconnected air network 400, ultimately forming a support surface that completely fits the part's shape.

[0042] In this method, the support block 300 can adaptively adjust in real time after the part is placed. The time from part placement to completion of adaptation is extremely short, and it can automatically reset without the need for resetting and adjustment after part removal. The resetting action is completed synchronously with part removal, and the next type of part can be placed immediately, achieving a seamless connection between part removal, resetting, and placement.

[0043] The above are merely preferred embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
