Description

Technical Field

[0001] The invention belongs to the technical field of automobile production, and in particular relates to a side panel frame positioning storage system and a use method thereof. Background Art

[0002] With the rapid development of the automotive industry and the continuous upgrading of automotive products, higher requirements have been put forward for automobile manufacturing. For example, in the production of white body welding in the automotive industry, fast production speed and high positioning accuracy have become a cutting-edge requirement for the production line. In addition, the diversity of car models not only caters to the purchasing needs of consumers, but also highlights the manufacturing and processing capabilities of automobile manufacturers. Therefore, the previous single-model production line has been difficult to meet the needs of automobile manufacturing, and the arbitrary mixed production of multiple models has become more and more common.

[0003] At present, most of the body-in-white welding production lines of vehicle manufacturers often need to realize flexible switching of multiple models to increase the flexibility of production and improve automobile production efficiency. Among them, using an automatic guided vehicle (AGV) to move and transfer side frames with heavy weight is an efficient transportation method. Since the number of side frames used is determined by the number of models planned in the production line stations, the side frames to be replaced must be stored in corresponding storage stations. CN115213604A discloses a switching storage system for body production and assembly. When multiple models are switched, when the previous side frame is at the processing station, the next side frame is transported to the guide rail system through the corresponding fixed storage station, carrier, transfer arm, clamp and loading part, and waits on the guide rail system for the previous side frame to be processed. When the previous side frame is away from the precision steel structure, the next side frame moves to the precision steel structure, thereby realizing the switching processing of multiple models at the precision steel structure.

[0004] However, the body-in-white welding production line has high requirements for the positioning accuracy of the fixtures, while the AGV itself has low repeatability. It is difficult for the AGV to ensure accurate positioning and clamping on the storage device, which makes it difficult to ensure the operational stability of the side panel frame.

[0005] Therefore, the technical problem of how to effectively position and clamp the side frame on the AGV at the storage position needs to be solved urgently. Summary of the invention

[0006] The purpose of the present invention is to provide a side enclosure frame positioning storage system and a method for using the system in order to effectively position and clamp the side enclosure frame on an AGV at a storage position.

[0007] The purpose of the present invention can be achieved by the following technical solutions:

[0017] Furthermore, the AGV tooling includes a self-contained lifting assembly, and the AGV tooling can move up and down between the lifting and transporting position and the parking frame position through the lifting assembly with the side frame fixed by the tooling clamping assembly.

[0018] Furthermore, the positioning parking component includes a parking component base installed on the bottom frame, and the parking component base is provided with a group of parking blocks for parking the side frame, and the parking blocks are provided with positioning pins that can be positioned with the side frame.

[0019] Furthermore, the side frame clamping assembly includes a second clamping arm and a second cylinder mounted on the positioning and parking assembly, and the second clamping arm and the second cylinder are connected via a connecting rod mechanism. The second cylinder drives the connecting rod mechanism to rotate to drive the second clamping arm to clamp the side frame.

[0020] Furthermore, the second cylinder has a gas-cut-off self-locking function.

[0022] Furthermore, the positioning and parking components are each provided with a frame identification component for identifying different vehicle models and frames, and the frame identification component is connected to a PLC control system.

[0055] Embodiment 1:

[0056] This embodiment provides a side frame positioning storage system and a method for using the same. Figure 1-3 As shown, the positioning and storage system includes a bottom frame 1 on which an AGV tooling positioning unit 2 and a side frame parking unit 3 are installed, which are used to position the AGV tooling 4 entering the positioning and storage system and store the side frame 5 carried by the AGV tooling 4.

[0057] The AGV tooling positioning unit 2 includes a roller guide assembly 21 symmetrically arranged along the entry direction of the AGV tooling 4, a tooling clamping assembly 22 for locking the AGV tooling 4, and an air supply assembly 23 capable of supplying air to the AGV tooling 4 for releasing the side frame 5. The side frame parking unit 3 includes a positioning parking assembly 31 symmetrically arranged along the entry direction of the AGV tooling 4, and each positioning parking assembly 31 is provided with a side frame clamping assembly 32 for clamping the side frame 5.

[0058] The method for using the side frame positioning storage system of this embodiment includes the following steps:

[0059] S1: The AGV tooling 4 carrying the side frame 5 enters the storage station along the roller guide assembly 21, and the tooling clamping assembly 22 clamps the AGV tooling 4;

[0060] S2: The AGV tooling 4 descends to the parking position, the side frame 5 is parked on the positioning parking assembly 31, and the side frame clamping assembly 32 clamps the side frame 5;

[0061] S3: the air supply assembly 23 is connected to the AGV tooling 4 to input the air source, and the AGV tooling 4 releases the side frame 5;

[0062] S4: the air supply assembly 23 is disconnected from the AGV tooling 4, and the tooling clamping assembly 22 is opened to release the AGV tooling 4;

[0063] S5: The AGV tooling 4 continues to descend and leaves the storage station along the roller guide assembly 21.

[0064] Embodiment 2:

[0065] This embodiment provides a side frame positioning storage system, which is different from the embodiment 1 in that the roller guide assembly 21 of this embodiment includes a plurality of roller supports 211 arranged along a linear direction and roller bearings 212 rotatably mounted on the roller supports 211, and adjacent roller supports 211 are connected by connecting beams 213 (such as Figure 4 As shown). The roller guide assembly 21 can be precisely corrected when the AGV tooling 4 enters the storage station. In addition, an X-direction adjustment gasket 214 is provided between the roller support 211 and the bottom frame 1 of this embodiment, and the roller bearing 212 is adjusted to the theoretical spatial position by increasing or decreasing the thickness of the gasket.

[0066] The tooling clamping assembly 22 of this embodiment is as follows Figure 5 As shown, it includes a tool clamping assembly body 221 installed on the bottom frame 1 and a first clamping arm 222 arranged on the tool clamping assembly body 221, and the first clamping arm 222 is connected to a first cylinder 223 that can drive it to clamp the AGV tool 4. A tool positioning sensor 224 is installed on the tool clamping assembly body 221, and the tool positioning sensor 224 is connected to the PLC control system. A limit block 225 and a buffer 226 are also installed on the tool clamping assembly body 221 of this embodiment. The limit block 225 is used to fix the AGV tool 4 in the correct position together with the first clamping arm 222 after the AGV tool 4 enters the storage position. The buffer 226 is used to play a role of flexible protection when the AGV tool 4 enters the storage position and during the clamping process, to prevent excessively fast collisions between devices and reduce parts loss.

[0067] The AGV tooling 4 of this embodiment is as follows Figure 6As shown, it includes an AGV tooling clamping assembly 41 for clamping the side frame 5 and a gas-off self-locking cylinder 42 connected to the AGV tooling clamping assembly 41. The gas-off self-locking cylinder 42 can drive the AGV tooling clamping assembly 41 to flip to clamp the side frame 5. The AGV tooling 4 of this embodiment is equipped with a lifting assembly 43, and the self-lifting function of the AGV tooling 4 can be realized by a conventional cylinder, which is used to park the side frame 5 carried by the AGV tooling 4 on the positioning parking assembly 31. The working principle of the gas-off self-locking cylinder 42 of this embodiment is: when the air source enters the gas-off self-locking cylinder 42, the air flows into the cylinder through the valve to move the piston. When the air source is cut off, the air pressure no longer provides support, the valve is compressed by the spring and closes the inlet and outlet of the gas, so that the gas-off self-locking cylinder 42 maintains the current state, and the gas pressure continues to increase until a balance point is reached to ensure the self-locking stability of the piston.

[0068] The gas supply assembly 23 of this embodiment is as follows Figure 7 As shown, it includes an air supply assembly body 231 installed on the bottom frame 1 and an air supply cylinder 232 arranged on the air supply assembly body 231. The top of the telescopic rod of the air supply cylinder 232 is provided with an air supply end 233, which can be connected to the air inlet end of the air cut-off self-locking cylinder 42, and the piston rod is driven to move again through the input source to realize the release of the AGV tooling clamping assembly 41. A magnetic switch 234 is also provided in the cylinder body groove of the air supply cylinder 232 of this embodiment, which is used to detect whether the cylinder telescopic state is in place.

[0069] Embodiment 3:

[0070] This embodiment provides a side frame positioning and storage system, which is different from the embodiment 1 in that the positioning and parking assembly 31 of this embodiment includes a parking assembly base 311 installed on the bottom frame 1. Figure 8 As shown, a group of parking blocks 312 for parking the side frame 5 are provided on the parking assembly base 311 , and positioning pins 313 that can be positioned with the side frame 5 are provided on the parking blocks 312 .

[0071] The side frame clamping assembly 32 of this embodiment is as follows: Fig. 9 As shown, it includes a second clamping arm 322 and a second cylinder 323 installed on the parking component base 311. The second clamping arm 322 and the second cylinder 323 are connected through a connecting rod mechanism 321. The second cylinder 323 drives the connecting rod mechanism 321 to rotate to drive the second clamping arm 322 to clamp the side frame 5.

[0072] Embodiment 4:

[0073] This embodiment provides a side frame positioning and storage system, which is different from the embodiment 3 in that the side frame 5 can be divided into a left side frame and a right side frame (such as Figure 1 and Figure 3 The side frame of the left side and the right side frame are respectively). In order to realize efficient identification of different vehicle models and different side side frames 5, the two positioning and parking components 31 are provided with a frame identification component 33 for identifying different vehicle models and frames. Fig.10 As shown, each frame identification component 33 includes a group of frame identification sensors 331 that can respectively identify different side frame 5, and each frame identification sensor 331 is connected to the PLC control system to feed back the corresponding side frame 5 information.

[0074] The frame recognition component 33 of this embodiment includes four frame recognition sensors 331, which recognize side frames 5 of different models according to the combination of two of them, and can recognize up to 6 side frames 5 of different models. If more models are required, the number of frame recognition sensors 331 can be planned according to the total number of models. Two steel blocks are installed at the corresponding positions on the side frames 5 according to different combinations as sensors, so as to achieve targeted recognition of different side frames 5.

[0075] Embodiment 5:

[0076] The present embodiment provides a side frame positioning and storage system and a specific method of use. The side frame positioning and storage system of the present embodiment is divided into an AGV tooling positioning unit 2 and a side frame parking unit 3 according to the corresponding different equipment.

[0077] The AGV tooling positioning unit 2 is installed on the bottom frame 1. The roller guide components 21 on both sides of the bottom frame 1 in the X direction can play a precise correction role when the AGV tooling 4 enters the storage system. The tooling clamping component 22 set in the Y direction of the bottom frame 1 is used to lock the AGV tooling 4 after the AGV tooling 4 is in place. When the AGV tooling 4 is lowered to the height of the parking side frame 5, the air supply component 23 is connected to open the air-off self-locking cylinder 42 on the AGV tooling 4 to release the side frame 5. The AGV tooling 4 can be precisely moved up and down between the lifting and transportation position and the parking frame position with the side frame 5 through the lifting component 43 when the tooling clamping component 22 is fixed.

[0078] The side frame parking unit 3 is installed at the top of both sides of the bottom frame 1 in the X direction, and is located on the outside of the roller guide assembly 21. The side frame clamping assembly 32 is driven by the second cylinder 323 to rotate the connecting rod mechanism 321, thereby driving the second clamping arm 322 to clamp and fix the side frame 5. The second cylinder 323 itself also has a self-locking function when the air is cut off. The dead point mechanism inside the second cylinder 323 can ensure that the mechanism is not opened when force is applied. The positioning pin 313 of the positioning parking assembly 31 can ensure that the side frame 5 is accurately in place and can effectively position the side frame 5. The side frame clamping assembly 32 and the positioning assembly positioning parking assembly 31 can be used together for parking the left side frame and the right side frame. The positioning and parking components 31 on both sides are provided with frame recognition components 33 for identifying different vehicle models and frames. The frame recognition sensors 331 of the frame recognition components 33 can recognize different vehicle models and side frame frames 5 on different sides by combining in pairs, so as to be compatible with the storage of the left and right side frame 5. The storage device design is unified through the shared side frame clamping component 32 and the positioning and parking component 31, avoiding symmetrical manufacturing, and reducing the manufacturing volume according to the work station planning requirements to reduce the manufacturing cost.

[0079] The structure of the AGV tooling positioning unit 2 of this embodiment includes a roller guide assembly 21, a tooling clamping assembly 22 and an air supply assembly 23. The roller guide assembly 21 is as shown in FIG. Figure 5 As shown, it includes a roller bearing 212, a roller support 211, a connecting beam 213 and an X-direction adjustment gasket 214. The tooling clamping assembly 22 is as shown in FIG. Figure 6 , including a tool clamping assembly body 221, a first cylinder 223, a first clamping arm 222 and a tool positioning sensor 224. The action sequence of the tool clamping assembly 22 is that when the AGV tool 4 is in the storage position, a signal is sent to the PLC control system in the production line station. After the first cylinder 223 drives the first clamping arm 222 to clamp the AGV tool 4, the tool positioning sensor 224 triggers a signal to confirm that the AGV tool 4 is in place. Figure 7 As shown, it includes an air supply component body 231 , an air supply cylinder 232 and an air supply end 233 at the top of the air supply cylinder 232 .

[0080] The side frame parking unit 3 of this embodiment includes a positioning parking component 31, a side frame clamping component 32 and a frame identification component 33. Figure 8 As shown, it includes a connecting rod mechanism 321, a second clamping arm 322, and a second cylinder 323, and the side frame clamping assembly 32 can be shared by the left and right side frame 5. Fig. 9As shown, it includes a parking component base 311 installed on the bottom frame 1, and a group of parking drag blocks 312 and positioning pins 313 on the parking component base 311, and the positioning parking component 31 is also shared by the side surrounding frames 5 on the left and right sides. Fig.10 As shown, there are installations on both sides of the bottom frame 1 in the X direction, which include a mounting seat and a plurality of frame identification sensors 331 arranged on the mounting seat to identify the left and right side frame 5 corresponding to different vehicle models.

[0081] The working principle and application of the side frame positioning storage system of this embodiment are as follows:

[0082] (1) The AGV tooling 4 enters the storage position along the roller guide assembly 21 of the AGV tooling positioning unit 2, and relies on the roller guide assembly 21 to constrain the positioning components on the AGV tooling 4 in the X direction to accurately position them. The shortest spacing between the roller bearings 212 on both sides relative to the positioning components of the AGV tooling 4 is reserved at 0.1-0.2mm. The repetition accuracy of AGVs currently on the market is not high, generally around ±10mm, and the high accuracy is only around ±5mm. The accuracy cannot meet the use requirements of the overall assembly station and cannot be accurately positioned. Therefore, it is necessary to use a high-precision roller guide assembly 21 to correct the position of the AGV tooling 4 when it enters, and ensure accurate positioning after it is in place;

[0083] (2) After the AGV tooling 4 arrives at the storage position, the tooling clamping assembly 22 of the AGV tooling positioning unit 2 installed in the Y direction of the bottom frame 1 clamps the AGV tooling 4. This fit reserves a clearance tolerance of 0.3 mm to ensure that the AGV tooling 4 is accurately positioned in the Y direction.

[0084] (3) The AGV tooling 4 is lowered to the parking position, so that the side frame 5 falls on the positioning parking component 31 of the side frame parking unit 3, and the side frame clamping component 32 of the side frame parking unit 3 clamps the side frame 5. The side frame clamping component 32 and the positioning component positioning parking component 31 can fix and position the side frame 5 on the left and right sides. The frame identification component 33 on different sides identifies whether the side frame 5 is on the left or right side. After confirming the side where the side frame 5 is located, the frame identification component 33 identifies the product type corresponding to the side frame 5.

[0085] (4) The air supply assembly 23 of the AGV tooling positioning unit 2 is inserted into the air inlet end input air source of the AGV tooling 4 to release the AGV tooling clamping assembly 41 on the AGV tooling 4 for clamping and positioning the side enclosure frame 5 .

[0086] (5) The air supply assembly 23 of the AGV tooling positioning unit 2 is retracted and separated from the air inlet end of the AGV tooling 4 .

[0087] (6) The tool clamping assembly 22 of the AGV tool positioning unit 2 opens to release the AGV tool 4 .

[0088] (7) After the AGV tooling 4 descends to the lowest position, it leaves the storage position along the roller guide assembly 21 of the AGV tooling positioning unit 2.

[0089] The above description of the embodiments is to facilitate the understanding and use of the invention by those skilled in the art. It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the present invention is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the scope of protection of the present invention.
