Description

Technical Field

[0001] The utility model relates to the field of automobile welding, and more specifically to a hemming station loading and unloading pre-assembly platform with a switchable roof. Background Art

[0002] New energy vehicles continue to penetrate the automotive industry, and the number of cars on the road increases. Major automakers have proposed personalized and customized solutions in the vehicle manufacturing process. For example, panoramic skylights have appeared on car roofs, and double skylight structures have appeared on MPV models. In the installation and manufacturing of these customized car roofs, the skylight position needs to be cut after pressing and forming. After cutting, the substrate and fabric where the skylight needs to be installed need to be separated to ensure the installation of the skylight. After the customized installation of the car roof is completed, the robot will grab the roof to the flexible positioning device. After the positioning is completed, the welding robot will weld the roof. After completion, the handling robot will grab the next part. Therefore, it is necessary to introduce a roof pre-assembly platform to place the roof so that the robot can position the car roof and facilitate grabbing.

[0003] However, there is currently a lack of pre-installation stations on the market that can automatically switch between roofs of different models. Car roofs of different models and sizes need to have separate workstations for hemming operations. One type of car roof corresponds to one workstation, so multiple robots are needed for operation. The investment cost of production equipment is high, which means that a large area is occupied and it is difficult to meet the requirements of high-speed production and fine manufacturing in modern factories. Utility Model Content

[0004] The purpose of the utility model is to overcome the problem in the prior art that the vehicle roof pre-assembly platform cannot automatically switch for vehicle roofs of different models, and to provide a switchable roof rolling station loading and unloading pre-assembly platform, so that the vehicle roof pre-assembly platform can be switched for vehicle roofs of different models, and one pre-assembly platform can realize loading and unloading of different vehicle roofs.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A rolling station loading and unloading pre-assembly platform with a switchable roof is provided, comprising a base, a driving device, a first frame fixed on the base and a second frame slidably connected to the base, the top of the first frame and the top of the second frame forming a table surface for placing the vehicle roof, the driving device being fixedly connected to the first frame or the base, the driving device being used to drive the second frame to slide along the base, the base being provided with a plurality of positioning parts according to the size of the vehicle roof, the second frame being provided with a locking member, the locking member cooperating with any of the positioning parts to fix the second frame.

[0007] The utility model provides a roll hemming station loading and unloading pre-assembly table for a switchable roof, wherein the base is fixed on the ground, and the top of the first frame and the top of the second frame form a table for placing the vehicle roof, and the table and the placement surface of the vehicle roof have at least three support points, so that the vehicle roof support is placed on the table. When it is necessary to switch the vehicle model for production, the operator operates the control system to select the vehicle model to be processed, and then the driving device drives the second frame to slide along the base. When the locking piece fixed on the second frame reaches the position of the target positioning part, the locking piece cooperates with the positioning part to fix the second frame on the base, avoiding relative slippage between the second frame and the base, completing the vehicle model switching, and then the operator lifts the vehicle roof to be processed and places it on the table to complete the placement of the vehicle roof, and then the locator identifies the vehicle model and sends the coordinates of the vehicle roof to the robot, so as to facilitate the subsequent robot to grab the parts.

[0008] Furthermore, the positioning parts are arranged in a straight line along the sliding direction of the second frame. A single locking member can be used to fix multiple positioning parts, thus saving materials and simplifying the structure.

[0009] Furthermore, the drive device is a linear drive member, the fixed end of which is fixedly connected to the base, the output end of which is fixedly connected to the second frame, and the sliding direction of the second frame is parallel to the driving direction of the linear drive member. The linear drive member is fixed at one end and fixed at the other end to the second frame. Therefore, by extending and retracting the linear drive member, the second frame can slide on the base, thereby changing the distance between the first frame and the second frame, and thus changing the size of the table, so that car roofs of different sizes can be accommodated.

[0010] Furthermore, the positioning portion is a bayonet, and the locking member includes a positioning pin and a linear motor fixed to the second frame. The positioning pin is fixedly connected to the output shaft of the linear motor, and the linear motor is used to drive the positioning pin to enter or leave the bayonet. During the switching process, when the sensor senses that the positioning pin has reached the target bayonet, the linear motor will drive the positioning pin to perform linear motion, causing it to enter the bayonet. The positioning pin and the bayonet are engaged, thereby fixing the second frame and preventing relative slippage between the second frame and the base. When the operator operates the console to switch the vehicle model, the positioning pin will leave the bayonet, releasing the fixed state between the first frame and the second frame, allowing the vehicle model to continue to be adjusted.

[0011] Furthermore, a slide rail is provided at the bottom of the second frame, and a slide rail seat corresponding to the slide rail is provided on the base, wherein the slide rail is slidably connected to the slide rail seat. The cooperation between the slide rail and the slide rail seat can prevent the second frame from deflecting in directions other than the sliding direction, thereby improving stability and enhancing the sliding compliance between the slide rail and the slide rail seat.

[0012] Furthermore, clamping members are installed at the top of each of the first and second frames, which are used to clamp the vehicle roof. When the second frame is fixed, the device forms a table for placing a designated vehicle model. The operator then lifts the vehicle roof and places it on the table. The clamping members can then hold the vehicle roof in place, preventing it from shifting when the robot grasps the part, thereby improving stability.

[0013] Furthermore, the first and second frames are each provided with a plurality of support members, each of which is detachably connected to the first and second frames. The support members on the first and second frames are used to support the vehicle roof. The support members on the first and second frames respectively provide support for the vehicle roof, ensuring a more balanced and stable placement of the vehicle roof on the table. The support members are detachably connected to the first and second frames, and the position and number of the support members can be adjusted according to actual needs.

[0014] Furthermore, the support member is L-shaped, and the two ends of the roof are located at the inner corners of the L-shaped support member. The L-shaped support member can provide vertical upward support for the roof and limit the two sides of the roof to prevent the roof from deflecting.

[0015] Furthermore, the top of the first frame and the top of the second frame form a table with an angle to the ground. The operator usually holds the roof of the vehicle with one hand high and the other hand low, and the table with a certain angle to the ground makes it easier for the operator to place the parts.

[0016] Furthermore, the top of the base is provided with an inclined surface tilted toward the ground, making it easier for operators to get on and off and avoid tripping.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The base is equipped with multiple positioning parts according to the size of the vehicle roof. When the vehicle model is switched, the driving device drives the second frame to slide along the base. The locking member cooperates with the positioning part to fix the second frame on the base, preventing the first and second frames from sliding relative to each other, completing the vehicle model switch with better convenience.

[0019] 2. The setting of the clamping parts can clamp the roof after it is placed, avoiding displacement of the roof when the robot grabs the parts, and improving stability;

[0020] 3. The setting of the support parts can not only provide support for the car roof but also provide limits on both sides of the car roof, so that the car roof can be installed on the table stably and balanced. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Example 1

[0028] This embodiment is the first embodiment of a roll-edge station loading and unloading pre-assembly station with a switchable top cover. Figure 1 and Figure 3As shown, the vehicle comprises a base 100, a driving device 200, a first frame 300 fixed to the base 100, and a second frame 400 slidably connected to the base 100. The top of the first frame 300 and the top of the second frame 400 form a table for placing the vehicle roof. The driving device 200 is a linear driving member 210. In this embodiment, the linear driving member 210 is a cylinder. In addition, the linear driving member 210 can also be a linear motor, a hydraulic cylinder, etc. The fixed end of the linear driving member 210 is fixedly connected to the base 100, and the output end of the linear driving member 210 is connected to the second frame 400. The frame 400 is fixedly connected, the sliding direction of the second frame 400 is parallel to the driving direction of the linear drive member 210, the base 100 is provided with four positioning parts 110 according to the size of the vehicle roof, and the four positioning parts 110 are arranged in a straight line along the sliding direction of the second frame 400, and the second frame 400 is provided with a locking member 410. In this embodiment, the positioning part 110 is a bayonet 111, and the locking member 410 includes a positioning pin 411 and a linear motor 412 fixed to the second frame 400. The positioning pin 411 can cooperate with any bayonet 111 to fix the second frame 400.

[0029] The working principle of this embodiment is as follows:

[0030] The base 100 is fixed on the ground, and the top of the first frame 300 and the top of the second frame 400 form a table for placing the car roof. The table and the placement surface of the car roof have at least three support points, so that the car roof is supported and placed on the table. When it is necessary to switch the car model for production, the operator operates the console to select the car model to be processed, and then starts the linear drive 210. Since one end of the linear drive 210 is fixed and the other end is fixed to the second frame 400, the linear drive 210 is extended and retracted to allow the second frame 400 to slide on the base 100, thereby changing the distance between the first frame 300 and the second frame 400, and then changing the size of the table, so that car roofs of different sizes can be placed. When the sensor senses that the positioning pin 411 reaches the position of the target positioning part 110, the linear motor will drive the positioning pin 411 to move linearly, so that the positioning pin 411 penetrates The bayonet 111, the positioning pin 411 and the bayonet 111 are engaged with each other to fix the second frame 400 and prevent the second frame 400 from slipping. When the operator operates the console to switch the vehicle model, the positioning pin 411 will leave the bayonet 111 to release the fixing state between the first frame 300 and the second frame 400, and then the vehicle model can be adjusted to fix the second frame 400 on the base 100 to prevent the second frame 400 and the base 100 from slipping relative to each other. Then the operator lifts the vehicle roof to be processed and places it on the table to complete the placement of the vehicle roof. The positioning unit will then identify the vehicle model and send the coordinates of the vehicle roof to the robot to facilitate the subsequent robot to grasp the parts. Since the positioning parts 110 are arranged in a straight line along the sliding direction of the second frame 400, one locking member 410 can be used to fix multiple positioning parts 110, saving materials and making the structure simpler.

[0031] Another embodiment of a positioning portion 110 is provided herein. Unlike the aforementioned embodiment, the linear drive member 210 is fixed to the base 100, and the second frame 400 is provided with four positioning portions 110 that cooperate with the linear drive member 210. The four positioning portions 110 are arranged linearly on the second frame 400 along the sliding direction of the second frame 400. When the second frame 400 slides, the positioning portions 110 also move with it. When the positioning portion 110 corresponding to the target vehicle model moves to the position of the locking portion 410, the locking portion 410 cooperates with the target positioning portion 110, securing the second frame 400 to the base 100.

[0032] In addition, the positioning portion 110 can also be a card slot, and the locking member 410 includes a card buckle and a rotating drive member. The card buckle is rotatably connected to the second frame 400, and the output shaft of the rotating drive member is fixedly connected to the card buckle. When the vehicle model is switched, the card buckle reaches the card slot corresponding to the target vehicle model, and the rotating drive member drives the card buckle to rotate, so that the card buckle is engaged with the card slot, so that the second frame 400 is fixed.

[0033] Example 2

[0034] This embodiment is a second embodiment of a roll-edge station loading and unloading pre-assembly station with a switchable top cover. This embodiment is similar to the first embodiment, except that Figure 1 and Figure 2 As shown, a slide rail 420 is provided at the bottom of the second frame 400, and a slide rail seat corresponding to the slide rail 420 is provided on the base 100, and the slide rail 420 is slidably connected to the slide rail seat. Two clamping members 500 are provided on the top of the first frame 300 and the second frame 400. The clamping members 500 are used to clamp the car roof. Two support members 600 are provided on the first frame 300 and the second frame 400. The support members 600 are respectively threadedly connected to the first frame 300 and the second frame 400, and multiple mounting positions are also provided on the first frame 300 and the second frame 400. In this embodiment, the support member 600 is L-shaped, and the two sides of the car roof are located at the inner corners of the L-shaped support member 600. The support member 600 on the first frame 300 and the support member 600 on the second frame 400 are used to respectively support the two ends of the car roof.

[0035] The working principle of this embodiment is as follows:

[0036] When the second frame 400 is fixed, the device forms a table for placing the designated vehicle model. The operator then lifts the car roof and places it on the table. The clamping member 500 now clamps the car roof, preventing it from shifting while the robot is grasping the part. Once the robot has firmly grasped the car roof, the clamping member 500 is released, and the robot can move the car roof. The support members 600 on the first frame 300 and the support members 600 on the second frame 400 respectively support the car roof. The support members 600 are L-shaped, providing both vertical support for the car roof and limiting the two sides of the car roof to prevent it from shifting. Because multiple mounting positions are reserved on the first frame 300 and the second frame 400, the number and position of the support members 600 can be adjusted according to actual needs during the processing process.

[0037] Example 3

[0038] This embodiment is a third embodiment of a roll-edge station loading and unloading pre-assembly platform with a switchable top cover. This embodiment is similar to the first and second embodiments, except that Figure 1 As shown, the table formed by the top of the first rack 300 and the top of the second rack 400 forms an inclination angle of 30°-75° with the ground, and the top of the base 100 is further provided with an inclined surface 120 inclined toward the ground.

[0039] The working principle of this embodiment is as follows:

[0040] When placing the car roof, two operators usually hold the two sides of the car roof. The operators usually hold the car roof with one hand high and the other hand low. The table and the ground form a certain tilt angle, which can facilitate the operators to place the parts. The inclined surface 120 can facilitate the operators to go up and down and avoid tripping.

[0041] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
