Description

Technical Field

[0001] This invention relates to the field of automotive manufacturing tooling technology, and in particular to a multi-model side panel adhesive application auxiliary positioning tooling and its switching device. Background Technology

[0002] The side panel assembly is a crucial structure forming the left and right side walls of a car, constituting the passenger compartment. It also serves as the outer skin for the rear fenders, the front A, B, and C pillars, the two door frames, and the bottom edge beam. Furthermore, it supports the roof and connects the front and rear of the vehicle. It acts as a load-bearing frame, securing the front and rear windshields, mounting the side doors, and ensuring the vehicle's safety in side impacts. It possesses significant bending and torsional rigidity and strength.

[0003] When processing the side panel, hinges and other components need to be installed on it. If only spot welding is used for connection, it cannot achieve a sealing effect. At this time, sealant needs to be applied to prevent rainwater from entering the vehicle. Therefore, during the production process, sealant needs to be applied to designated areas of the side panel.

[0004] The patent application CN109822281A, entitled "A Fixture for Automobile Side Panel Assembly with Excellent Fixation", discloses a fixture for fixing the automobile side panel during welding. The fixture can also be used to apply adhesive to the automobile side panel.

[0005] Although the above solution can position and fix the outer side panel of the car during the glue application process, the different specifications and shapes of the outer side panels of different cars mean that the clamps cannot be used to clamp different outer side panels. This means that different clamps need to be used for different outer side panels, or the clamps need to be replaced in sets on the clamping base. Regardless of the method used, it increases the equipment and labor costs. Summary of the Invention

[0006] In view of this, the present invention proposes a multi-vehicle side panel adhesive application auxiliary positioning fixture and its switching device. By assembling and installing a set of fixtures for various specifications of automotive side panels, and replacing the parts that cannot be assembled and installed to adapt to various side panels, it is applicable to side panels of multiple vehicle models.

[0007] The technical solution of this invention is implemented as follows:

[0008] On one hand, the present invention provides a multi-vehicle side panel adhesive application auxiliary positioning fixture, including a base frame, a head support frame, a middle support frame, a rear positioning assembly, and a front positioning pin, wherein,

[0009] The head support frame is movably mounted on the base frame;

[0010] The middle support frame is fixed on the base frame. Both the head support frame and the middle support frame have multiple support mechanisms. Each support mechanism on the head support frame is used to support the A-pillar of the side outer panel of different vehicle models, and each support mechanism on the middle support frame is used to support the B-pillar of the side outer panel of different vehicle models.

[0011] The rear positioning component is detachably fixed to the base frame to support and secure the wheel arch portion of the side panel.

[0012] The front positioning pin is located on the base frame and is used to insert into the front positioning hole of the side panel.

[0013] Based on the above technical solutions, preferably, it also includes a linear module, which is fixed on the base frame and fixed to the bottom of the head support frame, and is used to drive the head support frame to perform linear movement.

[0014] Based on the above technical solutions, preferably, the tail positioning assembly includes a connecting frame, a wheel cover support assembly, a wheel cover clamping assembly, and a rear positioning pin, wherein...

[0015] The connecting frame is fixed to the base frame;

[0016] The wheel cover support assembly is fixed on the connecting frame and is used to support the wheel cover portion of the side panel.

[0017] The wheel cover clamping assembly is fixed on the connecting frame and is used to clamp and fix the wheel cover part of the side panel outer plate;

[0018] The rear positioning pin is located on the connecting bracket and is used to insert into the rear positioning hole of the side panel.

[0019] Based on the above technical solutions, preferably, it also includes a plug docking assembly, which is fixed on the base frame and used to connect the aircraft plug to the tail positioning assembly.

[0020] Based on the above technical solutions, preferably, the air path docking assembly is disposed on the base frame and the tail positioning assembly, and is used to allow the air path of the tail positioning assembly to be detachably connected to the base frame.

[0021] Based on the above technical solutions, preferably, it also includes a crossbeam support frame, which has multiple support mechanisms, and each support mechanism on the crossbeam support frame is used to support the side crossbeams of different vehicle models.

[0022] On the other hand, the present invention provides a switching device for disassembling or installing the aforementioned tail positioning assembly, the switching device comprising a mating seat and a docking mechanism, wherein...

[0023] The mating seat is fixed to the tail positioning component;

[0024] The docking mechanism is positioned opposite to the mating seat and is selectively fixed to the mating seat.

[0025] Based on the above technical solutions, preferably, the mating seat includes a fixing plate and two connecting ears, wherein,

[0026] The fixing plate is fixed to the tail positioning component, and the fixing plate has an alignment opening;

[0027] Both connecting ears are fixed to the fixing plate and are located on both sides of the alignment port.

[0028] More preferably, the docking mechanism includes a mounting bracket, a plug, a hook, and a drive unit, wherein,

[0029] The mounting bracket and the mating seat are arranged opposite to each other;

[0030] The plug is fixed on the mounting bracket and selectively inserted into the alignment port;

[0031] There are two hooks, both of which are hinged to the mounting bracket and located on both sides of the plug-in. The hooks selectively insert into the connecting ears.

[0032] The drive unit is located on the two claws and is used to push the two claws to insert or disengage from the connecting ear.

[0033] Based on the above technical solutions, preferably, the docking mechanism is fixed to a robotic arm or hoisting equipment.

[0034] The multi-vehicle side panel adhesive application auxiliary positioning fixture and its switching device of the present invention have the following advantages over the prior art:

[0035] (1) By installing multiple support mechanisms on the head support frame and the middle support frame, the multiple support mechanisms can be adapted to the side panel support operation of different models, thereby greatly reducing the number of support parts that need to be replaced. At the same time, a detachable rear support assembly is set up, and the remaining support and fixing parts that need to be replaced are all set on the rear support assembly. By replacing the entire rear support assembly, the mode switching for the side panel of different models can be directly completed, avoiding the risk that the operators need to replace the support and clamping parts as a set during actual operation, resulting in the loss or incorrect installation of the complete set of tooling. At the same time, it greatly reduces the time and cost required to replace the tooling.

[0036] (2) The head support frame is movably installed on the base frame through the linear module. When supporting the side outer panel of different models, at least two support mechanisms can be guaranteed to contact the A-pillar part of the side outer panel, which effectively improves the stability of the side outer panel and avoids the problem of insufficient support due to the limited support position of the A-pillar part.

[0037] (3) By setting up a plug docking component, when installing the rear positioning component, the air plug is pushed into the electrical socket by using a cylinder lifting method, thereby realizing the electrical connection between the rear positioning component and the chassis. If the air plug is directly fixed on the chassis, it is easy to damage the air plug when replacing the rear positioning component. By using a cylinder lifting, the air plug can be lifted and docked after the rear positioning component is positioned, which can effectively avoid damage to the air plug. At the same time, there is no need for manual plug docking, which further improves the efficiency of side panel positioning switching for different models.

[0038] (4) By setting up an air path docking component, when installing the tail positioning component, the upper air path block and the lower air path block contact and dock, thereby connecting the air path of the tail positioning component with the air path on the base frame. An elastic sealing plate is also required on the lower or upper air path block. During the contact process between the upper and lower air path blocks, the elastic sealing plate is compressed and deformed to seal the connection between the upper and lower air path blocks. No manual air path replacement docking operation is required, further saving the time of replacing the tail positioning component. Attached Figure Description

[0055] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0056] like Figure 2-4As shown in the three figures, the side panels of three different car models are illustrated. In the figures, a represents the A-pillar portion of the side panel, b represents the B-pillar portion, c represents the wheel arch portion, and d represents the upper crossbeam portion. The upper crossbeam portion is a subdivision of the A-pillar portion. Additionally, e and f in the figures represent the front and rear positioning holes, respectively. It can be seen that in the three schematic diagrams, the distance between the A-pillar and B-pillar portions is relatively small, while the distance between the wheel arch portion and the B-pillar portion differs significantly. Furthermore, the wheel arch portions of the side panels of different car models vary considerably in both size and shape. The front positioning holes are all located in the A-pillar portion of the side panel. Based on this, the present invention proposes a multi-car model side panel adhesive application auxiliary positioning fixture, which positions and fixes the side panels of different car models according to their shape and size, providing auxiliary fixation during adhesive application.

[0057] like Figure 1-13 As shown, the multi-vehicle side panel adhesive application auxiliary positioning fixture of the present invention includes a base frame 1, a head support frame 2, a middle support frame 3, a rear positioning assembly 4, and a front positioning pin 5, wherein... Figure 5 For the installation of this tooling Figure 2 A schematic diagram of the outer panel of the middle side wall.

[0058] The base frame 1 is fixed on the workbench or production line and serves as the main carrier and support component of the tooling. It is made of metal frame and the side with the outer side panel is inclined relative to the ground, forming an angle between 20° and 45° with the ground. This reduces the glue application stroke when the glue application robot applies glue to the outer side panel, thereby improving glue application efficiency. It also facilitates the robot to perform targeted glue application. The base frame 1 is equipped with A-pillar support station, B-pillar support station and wheel cover support station in sequence.

[0059] The head support frame 2 is movably installed at the A-pillar support position of the base frame 1. Multiple mounting positions are set on the head support frame 2, and a support mechanism 6 is fixed at each mounting position. The multiple support mechanisms 6 on the head support frame 2 are used to support the A-pillar part of the side panel of different vehicle models.

[0060] It should be noted that, in order to improve the stable support of the side panel, there are two head support frames 2, so that when supporting the side panel of different models, at least two support mechanisms 6 are in contact with the A-pillar part of the side panel.

[0061] Similarly, the head support bracket 2 is movably mounted on the base frame 1 because the A-pillar portion of the side panel needs to be connected to the front bulkhead of the car during subsequent installation, which limits the support space available for the A-pillar portion of the side panel. After setting two head support brackets 2, the sum of the widths of the two head support brackets 2 will obviously be greater than the portion of the side panel A-pillar connecting to the front bulkhead. Therefore, the head support bracket 2 is chosen to be movably mounted so that after the support mechanism 6 performing the support operation is replaced, the support mechanism 6 of the corresponding model's side panel can be moved to support the side panel.

[0062] The middle support frame 3 is fixed on the B-pillar support position of the base frame 1. The middle support frame 3 has multiple mounting positions. Similar to the head support frame 2, each mounting position is equipped with a support mechanism 6. The various support mechanisms 6 installed on the middle support frame 3 are used to support the B-pillar part of the side panel of different vehicle models.

[0063] To improve the stability of the B-pillar support for the side outer panel, at least two support mechanisms 6 need to contact the B-pillar of the side outer panel simultaneously. Therefore, the number of mounting positions on the central support frame 3 is twice that on a single head support frame 2. In other words, the number of mounting positions on the central support frame 3 is twice the number of mounting positions on a single head support frame 2. Since the width of the B-pillar of the side outer panel is larger than that of the A-pillar, the central support frame 3 does not need to be adjusted, and the support mechanisms 6 on it can all directly contact the B-pillar of the corresponding model's side outer panel.

[0064] The rear positioning component 4 is detachably fixed on the wheel cover support position of the base frame 1. After the wheel cover part of the side panel is placed on the rear positioning component 4, the rear positioning component 4 can directly position and clamp the wheel cover part of the side panel. Since the wheel cover part of the side panel of different models is quite different, the rear positioning component 4 needs to be replaced directly when fixing the side panel of different models.

[0065] It should be noted that a corresponding shelf needs to be set up next to the glue application line to place multiple rear positioning components 4 applicable to different side panel wheel covers. When applying glue to the side panels of different models, the rear positioning component 4 of the corresponding model side panel is removed from the shelf and installed on the base frame 1.

[0066] The front positioning pin 5 is set on the outside of the A-pillar support position of the base frame 1. Specifically, a bracket is installed on the base frame 1, and the front positioning pin 5 is set on the bracket. Under normal working conditions, the front positioning pin 5 remains in place. During the placement of the side panel, the front positioning pin 5 is inserted into the front positioning hole of the side panel to perform preliminary positioning of the side panel.

[0067] Although the front positioning holes of the side panel are in the same position in most models, there may be side panels with different front positioning hole positions during the manufacturing process. Therefore, in this embodiment, the number of front positioning pins 5 is set to two, and two cylinders are set on the bracket. The two front positioning pins 5 are controlled separately by the cylinders. When one of the front positioning pins 5 is used, a height difference is formed by the cylinder to prevent the other front positioning pin 5 from contacting the side panel. One of the two front positioning pins 5 is a commonly used positioning part, while the other is used for the side panel of a few models. At the same time, setting two front positioning pins 5 can avoid the need to specifically install the front positioning pins 5 during the subsequent glue application process.

[0068] Specifically, in this embodiment, a single head support frame 2 is provided with eight mounting positions, and a middle support frame 3 is provided with sixteen mounting positions. That is, this tooling can be adapted to the side panel of eight different car models for adhesive application. Correspondingly, in addition to the rear positioning component 4 installed on the base frame 1, seven more rear positioning components 4 need to be prepared for replacement and spare.

[0069] It should be noted that the support mechanism 6 includes a fixed seat, a drive cylinder, a movable connecting rod, and a support block. The fixed seat is fixed on the mounting position of the head support frame 2 or the middle support frame 3. The drive cylinder and the movable connecting rod are both hinged to the mounting seat. At the same time, the movable connecting rod is hinged to the movable end of the drive cylinder. The support block is fixed on the end of the movable connecting rod away from the drive cylinder. The drive cylinder can drive the movable connecting rod to rotate, and the rotation angle is at least ninety degrees. A limit pad is also provided on the mounting seat. After the movable connecting rod rotates to contact the limit pad, it is in the supported state of the support mechanism 6. At this time, the outer side panel of the corresponding vehicle model can be supported by the support block. On a single head support frame 2, there is one support mechanism 6 in the supported state. At the same time, on the middle support frame 3, there are two support mechanisms 6 in the supported state.

[0070] As a preferred embodiment, two linear modules 7 are also provided on the base frame 1. The two linear modules 7 are located on the same straight line, and the movable ends of the two linear modules 7 are fixed to the two head support frames 2 in a one-to-one correspondence. The linear modules 7 directly drive the head support frames 2 to perform linear movement, thereby adjusting the position to adapt to the positioning and fixing of different side panel outer panels. At the same time, it is convenient for electrical control and easy to change the support mode for side panel outer panels of different vehicle models.

[0071] In this embodiment, specifically, the tail positioning assembly 4 includes a connecting frame 41, a wheel cover support assembly 42, a wheel cover clamping assembly 43, and a rear positioning pin 44. The connecting frame 41, the wheel cover support assembly 42, and the wheel cover clamping assembly 43 are all fixed on the base frame 1. The wheel cover support assembly 42 cannot move. When the side panel is placed on the wheel cover support assembly 42, the wheel cover support assembly 42 supports the wheel cover portion of the side panel. The wheel cover clamping assembly 43 can be moved. When the device is open or closed, it can clamp the wheel cover part of the side panel. The rear positioning pin 44 is set on the connecting frame 41. After the rear positioning pin 44 is inserted into the rear positioning hole of the side panel, the front positioning pin 5 and the rear positioning pin 44 cooperate to position the entire side panel, so as to avoid the side panel from shifting slightly and affecting the glue application. A cylinder connected to the rear positioning pin 44 is set on the connecting frame 41. When the rear positioning pin 44 leaves the side panel, the cylinder drives the rear positioning pin 44 to move down.

[0072] It should be noted that after the glue is applied, the front positioning pin 5 and the rear positioning pin 44 retract, and the mechanical gripper picks up the side panel. Since the mechanical gripper also has two positioning pins, if the front positioning pin 5 and the rear positioning pin 44 do not retract, all four positioning pins will be positioned at the same time, resulting in over-positioning. Therefore, when the mechanical gripper picks up the part, the two positioning pins on this fixture need to be removed from the front and rear positioning holes of the side panel.

[0073] When placing the side panel, the front positioning pin 5 and the rear positioning pin 44 need to be extended in advance to position the side panel in advance. If the pins are extended to position the side panel after it has been placed, the support mechanism 6 is not as accurate as the two positioning pins, and it is likely to scratch the workpiece. Therefore, the pins should be extended first when placing the side panel, and then the side panel should be placed on the support mechanism 6.

[0074] To ensure that the side panel is in a stable position, positioning detection probes are installed on the outer sides of the front positioning pin 5 and the rear positioning pin 44 to detect whether the side panel is fully in place.

[0075] In this embodiment, to ensure a stable connection between the connecting frame 41 and the base frame 1, multiple cylinder-driven locking mechanisms are provided on the base frame 1. The compression mechanism is rotated by the cylinder to press the connecting frame 41 onto the base frame 1. At the same time, at least two positioning seats are provided on the side of the connecting frame 41 that contacts the base frame 1. The positioning seats are provided with pin holes, and the two positioning seats are located at two opposite corners of the connecting frame 41. Two pins are also provided on the base frame 1. After the connecting frame 41 is placed on the base frame 1, the pins are inserted into the positioning seats to initially position the connecting frame 41. Then, the locking mechanisms are used to press the connecting frame 41 to prevent it from coming off. It should be noted that at least two locking mechanisms are used to press the connecting frame 41.

[0076] In a preferred embodiment, a plug docking assembly 8 is also provided on the base frame 1. The plug docking assembly 8 is fixed on the base frame 1, and an electrical socket is provided on the connecting frame 41. The plug docking assembly 8 uses a cylinder lifting method to push the aircraft plug into the electrical socket, thereby realizing the electrical connection between the tail positioning assembly 4 and the base frame 1. If the aircraft plug is directly fixed on the base frame 1, it is easy to damage the aircraft plug when replacing the tail positioning assembly 4. By using a cylinder lifting method, the aircraft plug can be lifted and docked after the tail positioning assembly 4 has been positioned, which can effectively avoid damage to the aircraft plug.

[0077] In a preferred embodiment, the air path docking assembly 9 is mounted on the base frame 1 and the tail positioning assembly 4. The air path docking assembly 9 includes an upper air path block and a lower air path block, which are respectively fixed on the base frame 1 and the tail positioning assembly 4. When the base frame 1 and the tail positioning assembly 4 are docked and positioned, the upper air path block and the lower air path block contact each other and complete the docking, thereby connecting the air path of the tail positioning assembly 4 with the air path on the base frame 1. An elastic sealing plate is also required on the lower air path block or the upper air path block. During the contact process between the upper air path block and the lower air path block, the elastic sealing plate is compressed and deformed to seal the connection between the upper air path block and the lower air path block. The elastic sealing plate can be a rubber plate.

[0078] In order to supply air to each cylinder on the base frame 1, two solenoid valve assemblies are also installed on the base frame 1. One solenoid valve assembly is used to supply air to the fixed parts on the base frame 1, and the other solenoid valve assembly is dedicated to supplying air to the tail positioning assembly 4 through the air circuit docking assembly 9.

[0079] In a preferred embodiment, a crossbeam support frame 10 is also included. The crossbeam support frame 10 has eight mounting positions, and a support mechanism 6 is fixedly installed at each of the eight mounting positions. Each support mechanism 6 on the crossbeam support frame 10 is used to support the side upper crossbeam of different vehicle models. The side upper crossbeam mentioned here is located at the connection between the A-pillar and B-pillar of the side outer panel and belongs to the structure of the A-pillar. By setting the crossbeam support frame 10 to support the side upper crossbeam, the stability of the support for the side outer panel can be further improved.

[0080] like Figure 13-17 As shown, the switching device of the present invention is used to disassemble or install the rear positioning component 4 of the above-mentioned multi-model side panel adhesive auxiliary positioning fixture. The switching device includes a mating seat 11 and a docking mechanism 12.

[0081] There are two mating seats 11, both of which are fixed on the tail positioning component 4, specifically on the connecting bracket 41 of the tail positioning component 4. The two mating seats 11 are arranged opposite to each other, and the specific installation method can be bolt fixing.

[0082] Under normal operating conditions, the docking mechanism 12 does not contact the two mating seats 11. When it is necessary to replace the tail positioning component 4, the docking mechanism 12 needs to be moved to the outside of the corresponding tail positioning component 4 and fixed to the two mating seats 11 on it. The tail positioning component 4 can be taken away or installed on the base frame 1 when the docking mechanism 12 moves. It should be noted that during the disassembly of the tail positioning component 4, the locking mechanism on the base frame 1 needs to be released in advance.

[0083] Specifically, the mating seat 11 includes a fixing plate 111 and two connecting ears 112. The fixing plate 111 is fixed on the tail positioning component 4. The fixing plate 111 has an alignment opening 1111. The two connecting ears 112 are fixed on the fixing plate 111 and are located on both sides of the alignment opening 1111.

[0084] To cooperate with the mating seat 11 for fixing, the docking mechanism 12 includes a mounting frame 121, inserts 122, claws 123, and a drive unit 124. The mounting frame 121 is made of steel and has a mounting structure for installation on other equipment. Two inserts 122 are symmetrically fixed to the mounting frame 121. The distance between the two inserts 122 matches the distance between the alignment ports 1111 on the two mating seats 11, allowing each insert 122 to be inserted into one of the two alignment ports 1111 during docking. The number of claws 123 is... Four hooks 123 are hinged to the mounting bracket 121 and are located on both sides of the two plugs 122 respectively. The four hooks 123 correspond to the four connecting ears 112 respectively. There are two drive units 124. One drive unit 124 is located on two of the four hooks 123, and the other drive unit 124 is located on the other two hooks 123. The drive unit 124 can be a cylinder. By pushing the two hooks 123, the claws of the two hooks 123 rotate toward the plug 122, thereby hooking the corresponding connecting ears 112, so that the mating seat 11 and the docking mechanism 12 are relatively fixed.

[0085] A solenoid valve assembly is also provided on the mounting bracket 121 to supply air to the drive unit 124.

[0086] In this embodiment, the docking mechanism 12 is fixed to a robotic arm or lifting equipment, preferably to a robotic arm. This allows for faster replacement of the tail positioning component 4 by directly using the robotic arm. Additionally, the shelf can be directly positioned next to the robotic arm for easy access to the corresponding tail positioning component 4.

[0087] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
