Description

Technical Field

[0001] This invention relates to the field of automotive assembly technology, and in particular to a parallelized clamp assembly device and control method based on a rotary buffer table. Background Technology

[0002] An automated automotive seat clamp installation production line typically consists of a seat loading area, a shaping area, a rotating buffer zone, a clamp installation area, and an unloading area. The motor drives the lead screw to load the seat, and a transport robot moves the seat to the shaping station. After shaping and positioning, the transport robot moves the seat to the rotating buffer table, and then rotates it to the clamp assembly area. The clamp installation robot assembles the clamps, and then the transport robot moves the clamps to the unloading area. Finally, the motor drives the lead screw to move the tray and unload the seat.

[0003] The existing assembly structures in the automatic installation production line for car seat clamps are mostly customized for a single model of car seat. When different models of car seat need to be assembled, new assembly structures need to be made and replaced simultaneously. In other words, the existing assembly structures cannot achieve adaptive matching for different models of car seat. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing assembly structures that cannot adaptively match different car seat models, and to propose a parallel clamping assembly device and control method based on a rotating buffer platform.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The parallel clamping assembly equipment based on a rotating buffer stage includes a frame, a rotating structure, two parallel deformable assembly structures, an auxiliary shaping structure, and an active shaping structure.

[0007] The deformable assembly structure is used to house the car seat basin, and it includes: an assembly plate, a base rod structure, and a deformable top rod structure;

[0008] The base rod structure is used to install the auxiliary shaping structure, and the base rod structure includes multiple mounting base rods;

[0009] The deformable push rod structure includes multiple telescopic push rods arranged in an array. These telescopic push rods change their length by telescopically extending and retracting to match the shape of the bottom of the car seat.

[0010] The auxiliary shaping structure includes an adaptive auxiliary net structure, which is used to support the car seat and provide positioning for the deformable push rod structure;

[0011] The active shaping structure, in conjunction with the auxiliary shaping structure, is used to constrain the car seat and provide positioning for the deformable pushrod structure.

[0012] As a further embodiment of the present invention, the telescopic top rod includes a bottom rod, a movable magnetic structure, a telescopic groove, a telescopic magnetic structure, and a movable top rod;

[0013] The movable magnetic structure includes three fixed electromagnetic blocks and two movable magnetic blocks. The three fixed electromagnetic blocks are fixedly installed at the top, middle and bottom of the base rod, respectively. The two movable magnetic blocks are slidably sleeved on the base rod and located between the three fixed electromagnetic blocks.

[0014] The expansion joint is installed at the top of the bottom rod, and a limit groove is provided on its side;

[0015] The telescopic magnetic structure includes two mutually exclusive telescopic magnetic blocks, both of which are disposed in the telescopic groove;

[0016] The movable top rod is installed in the telescopic groove, and its bottom end is fixedly connected to the telescopic magnetic block located above.

[0017] As a further aspect of the present invention, the fixed electromagnetic block located in the middle of the bottom rod and the fixed electromagnetic blocks located at both ends of the bottom rod are mutually exclusive, and the three fixed electromagnetic blocks can synchronously change the magnetic direction.

[0018] As a further aspect of the present invention, the deformable push rod structure also includes a plurality of equally spaced sliding grooves, each sliding groove containing a plurality of telescopic push rods.

[0019] As a further embodiment of the present invention, connecting ropes are provided on the sides of the two movable magnetic blocks on the base rod. One end of the connecting rope is fixedly connected to the fixed electromagnetic block located in the middle of the adjacent base rod. When the movable magnetic block on one of the base rods moves away from the fixed electromagnetic block in its middle, it will pull the adjacent base rod to move through the connecting rope. Reset structures are also provided at both ends of the sliding groove. The reset structures are fixedly connected to the adjacent telescopic top rods and are used to pull multiple base rods to reset.

[0020] As a further embodiment of the present invention, a hydraulic telescopic pipe network is provided between the multiple telescopic top rods, and multiple hydraulic limit clamps are provided at the output end of the hydraulic telescopic pipe network for clamping the corresponding moving top rod at the limit groove.

[0021] As a further embodiment of the present invention, the adaptive auxiliary net structure includes multiple auxiliary blocks and a pull net structure. The multiple auxiliary blocks are respectively installed on multiple mounting base rods. A reset frame is slidably inserted into the auxiliary block. The reset frame is H-shaped and a reset spring is installed on the reset frame. The connector of the pull net structure is connected to the side of the reset frame away from the reset spring.

[0022] As a further embodiment of the present invention, an active shaping structure is disposed on one side of a deformable assembly structure and corresponds to one of the deformable assembly structures. The active shaping structure includes a lifting component and a lower pressure plate, and the lower pressure plate is driven by the lifting component to move up and down along the lifting component.

[0023] As a further embodiment of the present invention, the rotating structure includes a drive motor, a bevel gear structure, and a rotating seat. The drive motor drives the rotating seat through the bevel gear structure, and the rotating seat is installed in the middle of the bottom of the two deformable assembly structures.

[0024] The control method for a parallelized clamp assembly device based on a rotary buffer stage includes the following steps:

[0025] Step 1: Place any type and shape of car seat pan onto the mesh structure. The car seat pan deforms due to the pressure of gravity on the mesh structure, and the corresponding reset frame moves along the auxiliary block a different distance according to the shape of the bottom of the car seat pan.

[0026] Step 2: Then the lifting assembly drives the lower pressure plate to press down on the top of the car seat, forming a limit on the car seat together with the mesh structure, and correcting and constraining the posture of the car seat on the mesh structure. At this time, the bottom of the car seat presses against the moving push rod (because the two moving magnetic blocks repel each other, the moving push rod always remains in an extended state, and therefore will be squeezed by the bottom of the car seat).

[0027] Step 3: Next, the fixed electromagnetic block is activated, causing the two movable magnetic blocks to move towards the top and bottom of the base rod respectively. This, in turn, pulls the adjacent telescopic top rods through the connecting rope, causing the movable top rods in each telescopic top rod to misalign with the net rope of the mesh structure, ensuring they are firmly against the bottom of the car seat. At the same time, the fixed electromagnetic block at the top of the base rod repels the movable magnetic block at the bottom of the telescopic groove, forcing the two repelling movable magnetic blocks to move upward along the telescopic groove, further driving the movable top rods to press firmly against the bottom of the car seat.

[0028] Step 4: Next, start the hydraulic telescopic pipeline. The hydraulic telescopic pipeline will drive the hydraulic limit clamp to clamp the moving top rod from the limit groove, so that the position of the moving top rod is fixed.

[0029] Step 5: The lifting assembly drives the lower pressure plate to rise, remove the car seat pan as a template, remove the adaptive auxiliary net structure from the mounting base rod, promote the shaping of the deformable assembly structure, and realize the adaptation of the deformable assembly structure to the car seat pan.

[0030] Step 6: The drive motor drives the rotating seat to rotate through the bevel gear, switching the positions of the two deformable assembly structures. Then the above process is repeated so that both deformable assembly structures are adapted to the car seat.

[0031] Step 7: The external handling robot places the car seat onto one of the deformable assembly structures and completes the clamping assembly. After assembly, the two deformable assembly structures are switched by rotating the structure, and the clamping assembly is performed again.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] When adapting to different models of car seats, this application does not require replacing the main components of the deformable assembly structure. It can be adapted to different models and different bottom contours of car seats simply by adjusting the position of the telescopic push rod. This solves the limitation of traditional special fixtures that require one type of fixture per type, greatly reducing the fixture replacement cost and debugging time in multi-variety production. Furthermore, by utilizing the initial positioning of the adaptive auxiliary net structure, the attitude correction of the active shaping structure, the precise fitting of the telescopic push rod, and the locking of the hydraulic limit clamp, the deformable assembly structure is accurately matched with the car seat, effectively avoiding quality problems such as misinstallation, omission, or insufficient installation accuracy of the clamps.

[0034] The structural adjustments during the prototyping stage and the workstation switching during the assembly stage of this application are all achieved through automated equipment control. Only simple operations such as template placement, auxiliary structure disassembly, and finished product unloading need to be completed manually, which reduces the skill requirements of the operators and reduces errors caused by manual intervention.

[0045] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0046] like Figure 1 and Figure 2 As shown, the parallel clamping assembly equipment based on the rotating buffer stage includes a frame 100, a rotating structure 200, two parallel deformable assembly structures 300, an auxiliary shaping structure 400, and an active shaping structure 500.

[0047] The deformable assembly structure 300 is used to place the car seat basin, and includes: an assembly plate 310, a base rod structure 320 and a deformable top rod structure 330.

[0048] The base rod structure 320 is used to install the auxiliary shaping structure 400, and the base rod structure 320 includes multiple mounting base rods 321;

[0049] The deformable push rod structure 330 includes multiple telescopic push rods 331 arranged in an array. The multiple telescopic push rods 331 change their length by telescopic movement to match the shape of the bottom of the car seat.

[0050] The auxiliary shaping structure 400 includes an adaptive auxiliary net structure 410, which is used to support the car seat and provide positioning for the deformable push rod structure 330.

[0051] The active shaping structure 500, in conjunction with the auxiliary shaping structure 400, is used to constrain the car seat and provide positioning for the deformable push rod structure 330 by pressing.

[0052] like Figure 4 and Figure 7 As shown, the telescopic top rod 331 includes a base rod 332, a movable magnetic structure 333, a telescopic groove 334, a telescopic magnetic structure 335, and a movable top rod 336;

[0053] The movable magnetic structure 333 includes three fixed electromagnetic blocks 3331 and two movable magnetic blocks 3332. The three fixed electromagnetic blocks 3331 are respectively fixedly installed at the top, middle and bottom of the base rod 332. The two movable magnetic blocks 3332 are slidably sleeved on the base rod 332 and located between the three fixed electromagnetic blocks 3331.

[0054] The telescopic groove 334 is installed at the top of the bottom rod 332, and a limit groove 3341 is provided on its side;

[0055] The telescopic magnetic structure 335 includes two mutually exclusive telescopic magnetic blocks 3351, both of which are disposed in the telescopic groove 334.

[0056] The movable top rod 336 is installed in the telescopic groove 334, and its bottom end is fixedly connected to the telescopic magnetic block 3351 located above.

[0057] like Figure 7 and Figure 8 As shown, the fixed electromagnetic block 3331 located in the middle of the bottom rod 332 and the fixed electromagnetic blocks 3331 located at both ends of the bottom rod 332 are mutually exclusive, and the three fixed electromagnetic blocks 3331 can change their magnetic direction synchronously.

[0058] like Figure 4 and Figure 6 As shown, the deformable push rod structure 330 also includes multiple equally spaced sliding grooves 337, with multiple telescopic push rods 331 distributed in each sliding groove 337.

[0059] like Figure 7 As shown, each of the two movable magnetic blocks 3332 on the base rod 332 is provided with a connecting rope 340 on its side. One end of the connecting rope 340 is fixedly connected to the fixed electromagnetic block 3331 located in the middle of the adjacent base rod 332. When the movable magnetic block 3332 on one of the base rods 332 moves away from the fixed electromagnetic block 3331 in its middle, it will pull the adjacent base rod 332 to move through the connecting rope 340. The two ends of the sliding groove 337 are also provided with a reset structure 350. The reset structure 350 is fixedly connected to the adjacent telescopic top rod 331 and is used to pull multiple base rods 332 to reset.

[0060] like Figure 1 and Figure 5As shown, a hydraulic telescopic pipe network 360 is provided between multiple telescopic push rods 331. Multiple hydraulic limit clamps 361 are provided at the output end of the hydraulic telescopic pipe network 360, which are used to clamp the corresponding moving push rods 336 at the limit grooves 3341.

[0061] like Figure 1 and Figure 9 As shown, the adaptive auxiliary net structure 410 includes multiple auxiliary blocks 420 and a mesh structure 430. The multiple auxiliary blocks 420 are respectively installed on multiple mounting base rods 321. A reset frame 421 is slidably inserted into the auxiliary block 420. The reset frame 421 is H-shaped and a reset spring 422 is installed on the reset frame 421. The connector of the mesh structure 430 is connected to the side of the reset frame 421 away from the reset spring 422.

[0062] like Figure 1 and Figure 2 As shown, the active shaping structure 500 is located on one side of the deformable assembly structure 300 and corresponds to the position of one of the deformable assembly structures 300. The active shaping structure 500 includes a lifting component 510 and a lower pressure plate 520. The lower pressure plate 520 is driven by the lifting component 510 to move up and down along the lifting component 510.

[0063] like Figure 2 and Figure 3 As shown, the rotating structure 200 includes a drive motor 210, a bevel gear structure 220, and a rotating seat 230. The drive motor 210 drives the rotating seat 230 through the drive bevel gear structure 220. The rotating seat 230 is installed in the middle of the bottom of the two deformable assembly structures 300.

[0064] Control method for parallelized clamp assembly equipment based on rotary buffer stage:

[0065] Step 1: First, the operator or external auxiliary equipment smoothly places a car seat of the model to be assembled (as a fitting template) onto the mesh structure 430 of the adaptive auxiliary mesh structure 410 of one of the deformable assembly structures 300. Due to the weight of the car seat itself, the mesh structure 430 will adaptively deform along the contour shape of the bottom of the seat. The raised areas of the bottom of the seat will cause the mesh structure 430 at the corresponding position to sink, while the concave areas will keep the mesh structure 430 at a relatively high position. During this process, the connector of the mesh structure 430 will pull the corresponding position... The H-shaped reset frame 421 moves along the insertion track on the auxiliary block 420, and the moving distance is perfectly matched with the deformation degree of the mesh structure 430 (that is, the greater the pressure at the bottom of the seat, the farther the reset frame 421 moves). At the same time, the reset spring 422 on the reset frame 421 is stretched or compressed synchronously to provide elastic potential energy for subsequent reset. At this time, the adaptive auxiliary mesh structure 410 has initially achieved the bearing and positioning of the template seat through the deformation of the mesh and the movement of the reset frame 421, providing a basic contour reference for subsequent precise shaping.

[0066] Step Two: Next, activate the active shaping structure 500. The lifting component 510 of the active shaping structure 500 (such as a screw jack or cylinder drive mechanism) drives the lower pressure plate 520 to move slowly downwards until the lower surface of the lower pressure plate 520 is completely in contact with the top surface of the template base. During the continuous application of stable pressure, the lower pressure plate 520, together with the lower mesh structure 430, forms an upper and lower clamping effect on the template base, thereby limiting the position of the template base. At this time, the mesh structure 430 supports and conforms to the contour of the base from the bottom, and the lower pressure plate 520 applies uniform pressure from the top, correcting the template base on the mesh structure 430. The potential for offset or tilting ensures that the seat is positioned at the preset assembly reference position. At the same time, the bottom of the template seat will compress the telescopic push rods 331 arranged in an array in the deformable assembly structure 300 (because in the moving magnetic structure 333 of the telescopic push rod 331, the two moving magnetic blocks 3332 are kept in a repulsive state under the initial magnetic action of the fixed electromagnetic block 3331, so that the moving push rod 336 is always in an extended state. Therefore, when the bottom of the seat presses on the moving push rod 336, the moving push rod 336 will form a reverse support force, initially conforming to the bottom contour of the seat, providing mechanical feedback for subsequent precise shaping).

[0067] Step 3: Next, the equipment control system sends a start signal to the fixed electromagnetic blocks 3331 of the deformable assembly structure 300. The three fixed electromagnetic blocks 3331 synchronously change their magnetic direction, causing the fixed electromagnetic block 3331 located in the middle of the base rod 332 to repel the fixed electromagnetic blocks 3331 at both ends. Under this repulsive force, the two movable magnetic blocks 3332 originally located on either side of the middle fixed electromagnetic block 3331 will slide towards the top and bottom of the base rod 332, respectively. Since each movable magnetic block 3332 is connected to a connecting rope 340 on its side, and the other end of the connecting rope 340 is fixedly connected to the fixed electromagnetic block 3331 in the middle of the adjacent base rod 332, when a movable magnetic block 3332 on a single base rod 332 moves towards both ends, it will pull the adjacent base rod 332 slightly along the sliding groove 337 via the connecting rope 340, thereby driving the entire array... The telescopic top rods 331 of the column are finely adjusted so that the moving top rods 336 of each telescopic top rod 331 avoid the position of the net rope of the pull net structure 430 and fully abut against the solid area of ​​the bottom of the template basin. This avoids the problem of insufficient fit caused by the net rope blocking the fit. At the same time, the fixed electromagnetic block 3331 at the top of the bottom rod 332 will form a mutual repulsion force with the telescopic magnetic block 3351 at the bottom of the telescopic groove 334. The two telescopic magnetic blocks 3351 in the telescopic groove 334 are already in a mutual repulsion state. Under the action of the double mutual repulsion force, the two telescopic magnetic blocks 3351 will move upward along the telescopic groove 334, thereby driving the moving top rod 336, which is fixedly connected to the upper telescopic magnetic block 3351, to extend further upward and press tightly against the bottom of the template basin. This makes the top surface of the moving top rod 336 completely fit the bottom contour of the basin, achieving a precise replication of the bottom shape of the basin by the telescopic top rod 331 array.

[0068] Step 4: Next, start the hydraulic telescopic pipe network 360 system. The output end of the hydraulic telescopic pipe network 360 is connected to multiple hydraulic limit clamps 361 one by one. Driven by hydraulic power, each hydraulic limit clamp 361 will move along the limit groove 3341 on the side of the telescopic groove 334 until the clamping surface of the clamp is tightly fitted with the outer wall of the moving top rod 336. The structural design of the limit groove 3341 ensures that the hydraulic limit clamp 361 can accurately position the moving top rod 336 to the locking position. The moving top rod 336 is fixed at the current extension length by mechanical clamping to prevent it from shifting due to external force or magnetic changes. At this time, the shape of the telescopic top rod 331 array is completely fixed and accurately matches the shape of the bottom of the template basin.

[0069] Step 5: Subsequently, the lifting component 510 of the active shaping structure 500 drives the lower pressure plate 520 to move upward until the lower pressure plate 520 is completely separated from the car seat and returns to the initial high position. The operator manually removes the car seat as a template. At this time, due to the locking effect of the hydraulic limit clamp 361, the telescopic top rod 331 array of the deformable assembly structure 300 still maintains the shape adapted to the bottom of the seat. Then, the operator removes the adaptive auxiliary net structure 410 from the mounting base rod 321 of the base rod structure 320. Since the auxiliary net structure is only used for the initial positioning in the template adaptation stage, it is no longer needed after the shaping is completed. After disassembly, the top surface of the deformable assembly structure 300 is fully exposed, which facilitates the placement of the car seat and the clamping installation operation during subsequent actual assembly. Thus, the adaptation and shaping of the first deformable assembly structure 300 is completed.

[0070] Step Six: Next, start the rotating structure 200. After the drive motor 210 is powered on, it starts running and drives the active bevel gear in the bevel gear structure 220 to rotate through the output shaft. The active bevel gear meshes with the driven bevel gear, which in turn drives the rotating seat 230, which is fixedly connected to the driven bevel gear, to rotate around its own central axis (the rotation angle is 180 degrees to ensure that the two deformable assembly structures 300 completely exchange positions). After the rotating seat 230 stops, the second deformable assembly structure 300, which was not adapted before, moves to the adaptation station directly below the active shaping structure 500, while the first deformable assembly structure, which has been adapted, moves to the adaptation station. Then, move 300 to the assembly station on the other side. Then, repeat all the operations of steps one to five, place the template seat on the adaptive auxiliary net structure 410 of the second deformable assembly structure 300, correct the posture through the active shaping structure 500, drive the telescopic top rod 331 to accurately adapt and lock it through the hydraulic limit clamp 361, and finally remove the template and auxiliary net structure so that the second deformable assembly structure 300 also completes the adaptation and shaping with the car seat to be assembled. At this time, both deformable assembly structures 300 have the load-bearing form adapted to the car seat to be assembled, making full preparations for subsequent parallel assembly.

[0071] Step 7: The external handling robot places the car seat onto one of the deformable assembly structures 300 and completes the clamping assembly. After the assembly is completed, the two deformable assembly structures 300 are switched by rotating structure 200 and clamped again.

[0072] The beneficial effects of this application are:

[0073] When adapting to different models of car seats, this application does not require replacing the main components of the deformable assembly structure 300. It can adapt to different models and different bottom profiles of car seats simply by adjusting the position of the telescopic push rod 331. This solves the limitation of traditional special fixtures that require one type of fixture per type, greatly reducing the fixture replacement cost and debugging time in multi-variety production. Furthermore, by utilizing the initial positioning of the adaptive auxiliary net structure 410, the attitude correction of the active shaping structure 500, the precise fitting of the telescopic push rod 331, and the locking of the hydraulic limit clamp 361, the deformable assembly structure 300 is accurately matched with the car seat, effectively avoiding quality problems such as misinstallation, omission, or insufficient installation accuracy of the clamps.

[0074] The structural adjustments during the prototyping stage and the workstation switching during the assembly stage of this application are all achieved through automated equipment control. Only simple operations such as template placement, auxiliary structure disassembly, and finished product unloading need to be completed manually, which reduces the skill requirements of the operators and reduces errors caused by manual intervention.

10. A control method for a parallelized clamping assembly device based on a rotary buffer stage, characterized in that: The parallelized clamp assembly device based on a rotary buffer stage as described in claim 9 includes the following steps: S1: Place any type and shape of car seat pan on the mesh structure (430). The car seat pan deforms due to the pressure of gravity on the mesh structure (430), and pulls the corresponding reset frame (421) along the auxiliary block (420) a different distance according to the shape of the bottom of the car seat pan. S2: Then the lifting assembly (510) drives the lower pressure plate (520) to press down on the top of the car seat, forming a limit on the car seat together with the mesh structure (430), and correcting and constraining the posture of the car seat on the mesh structure (430). At this time, the bottom of the car seat presses against the moving push rod (336) (because the two moving magnetic blocks (3332) repel each other, the moving push rod (336) always remains in an extended state, and therefore will be squeezed by the bottom of the car seat). S3: Then the fixed electromagnetic block (3331) is activated, causing the two movable magnetic blocks (3332) to move towards the top and bottom of the bottom rod (332) respectively. Then, through the connecting rope (340), the adjacent telescopic top rod (331) is pulled to move, so that the movable top rod (336) in each telescopic top rod (331) is misaligned with the net rope of the pull net structure (430) and is in a firm contact with the bottom of the car seat. At the same time, the fixed electromagnetic block (3331) at the top of the bottom rod (332) is mutually repulsive with the movable magnetic block (3332) at the bottom of the telescopic groove (334), thereby forcing the two mutually repulsive movable magnetic blocks (3332) to move upward along the telescopic groove (334), further driving the movable top rod (336) to press against the bottom of the car seat. S4: Next, start the hydraulic telescopic pipeline (360), and drive the hydraulic limit clamp (361) to clamp the moving push rod (336) from the limit groove (3341) so that the position of the moving push rod (336) is fixed. S5: The lifting assembly (510) drives the lower pressure plate (520) to rise, remove the car seat pan as a template, remove the adaptive auxiliary net structure (410) from the mounting base rod (321), promote the shape of the deformable assembly structure (300), and realize the adaptation of the deformable assembly structure (300) to the car seat pan. S6: The drive motor (210) drives the rotating seat (230) to rotate through the bevel gear, switching the positions of the two deformable assembly structures (300), and then repeating the above process so that both deformable assembly structures (300) are adapted to the car seat. S7: The external handling robot places the car seat onto one of the deformable assembly structures (300) and completes the clamping assembly. After the assembly is completed, the two deformable assembly structures (300) are switched by the rotating structure (200) and clamped again.
