Description

Technical Field

[0001] The invention relates to the field of automobile exterior decoration, and more particularly to an automatic punching and cutting rotating platform. Background Art

[0002] At present, due to the particularity of the coating process, it is difficult to ensure the surface quality of the products after coating by using the technology of one-time injection molding to complete the molding of various radar holes, cleaning holes, and assembly holes on the surface of automotive accessories, especially automotive exterior accessories (front and rear bumpers) on the domestic and foreign markets. The main problem is that during injection molding, weld lines are likely to appear around the surface holes of the products, light refraction defects will be generated after coating, and the edges of the holes will produce fat edges (frame) effects after coating, especially European models use the edges of radar holes as decorative process edges, which determines that various hole types on the surface of automotive exterior products (front and rear bumpers) must be processed after coating.

[0003] There are two main punching methods: the first is a special punching machine, which is a special punching workstation for punching a single product. Its disadvantage is that it can only adapt to a single product and cannot flexibly adapt to the modern production trend of multiple varieties, small batches, and fast pace. The second is a robot workstation method, which fixes the product positioning membrane on the workbench, and the robot drives the punching unit to punch the fixed product. Its disadvantage is that when punching different types of holes on the same product, the robot needs to frequently replace the punching unit, which wastes the production cycle of a single product. When changing products, it also takes a lot of time to replace the product positioning membrane.

[0004] It can be seen that due to the different shapes of various holes on the surface of automotive exterior products (front and rear bumpers), the existing punching equipment cannot be universal. With the changes in products, especially the development of small batches and multiple varieties, the equipment of manufacturers is piling up, increasing the cost of site and equipment. In addition, the existing punching equipment is difficult to form a fully automatic assembly line production mode, and cannot meet the production requirements such as timeliness of planning, smooth logistics, stable process, and quality assurance. Summary of the invention

[0005] The present invention provides an automatic punching rotary platform, which solves the problems of single equipment, non-universality, high production cost and low production efficiency in conventional punching production methods of exterior plastic parts in the automobile industry in the prior art.

[0006] The present invention provides an automatic punching rotary platform, comprising a bracket, a rotary drive device, a platform body and at least one punching unit arranged on the upper surface of the platform body, wherein the platform body is mounted on the bracket through the rotary drive device;

[0007] The punching unit includes a punching machine and a avoidance device, a sliding device, and a positioning device fixed on the platform body. The punching machine is slidably connected to the sliding device, and the sliding device is arranged along the radial direction of the platform body. The avoidance device is located at one end of the sliding device close to the center of the platform body and is connected to the punching machine; the positioning device is located at one end of the sliding device close to the edge of the platform body and is connected to the punching machine.

[0008] In a feasible embodiment, the rotation driving device includes a driving member and a rotating shaft, the rotating shaft is arranged between the bracket and the platform body, and the driving member is connected to the rotating shaft to drive the platform body to rotate.

[0009] In a feasible embodiment, the driving member is a servo motor.

[0010] In a feasible embodiment, the avoidance device is a cylinder.

[0011] In a feasible embodiment, the sliding device is a sliding rail.

[0012] In a feasible embodiment, the positioning device is a positioning pin cylinder.

[0013] In a feasible embodiment, it further comprises a slip ring and a quick-connect connector, wherein the slip ring is connected to the quick-connect connector via an electric circuit and an air pipe, and the quick-connect connector is connected to the punching unit via an electric circuit and an air pipe.

[0014] In a feasible embodiment, there are eight punching units, and the eight punching units are evenly arranged along the circumference of the platform body.

[0015] In a feasible embodiment, the blade shapes of the punching machines of the eight punching units are different.

[0016] In a feasible embodiment, the automatic punching and cutting rotary platform further comprises a control system, and the control system is electrically connected to the rotary drive device, the positioning device, the avoidance device and the punching and cutting machine respectively.

[0017] The automatic punching rotating platform of the present invention distributes all the punching units evenly on the platform body, and automatically rotates the corresponding punching unit to the working position according to the type of hole to be punched. The robot moves the product and places the position on the product that needs to be punched on the punching unit for punching, thereby realizing the function of being compatible with multiple products and multiple hole shapes and switching quickly, and can fully adapt to the current multi-variety, small batch, and fast-paced production rhythm.

[0035] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings and described in detail.

[0036] like Figure 1As shown, the present invention provides an automatic punching rotary platform, comprising a bracket 1, a rotation drive device, a platform body 2 and at least one punching unit 3, the platform body 2 is installed on the bracket 1 through the rotation drive device, the rotation drive device is used to drive the platform body 2 to rotate, and the punching unit 3 is arranged on the upper surface of the platform body 2; the punching unit 3 includes a punching machine 34 and a avoidance device 31, a sliding device 32, and a positioning device 33 fixed on the platform body 2, the sliding device 32 is arranged along the radial direction of the platform body 2, the avoidance device 31 and the positioning device 33 are respectively located at two ends of the sliding device 32, the avoidance device 31 is located at one end close to the center of the platform body, and the positioning device 33 is located at the end of the sliding device away from the center of the platform body, and the punching machine 34 is slidably connected to the sliding device 32; the avoidance device 31 is connected to the punching machine 34, and is used to drive the punching machine 34 to slide on the sliding device 32, and the positioning device 33 is connected to the punching machine 34, and is used to lock the punching machine 34 on the slide rail so that it no longer slides.

[0037] The upper surface of the platform body 2 is usually arranged in a circular shape, which can rotate around its center, and the sliding device 32 is radially arranged on the upper surface of the platform body 2, so that the punching machine 34 can slide radially on the platform body 2. The position where the automatic punching rotating platform processes the product is called the working position. Since there are multiple punching machines 34 on the platform body 2, different punching machines 34 are required to process different types of products. Therefore, during the production process, the punching machine 34 needs to be replaced at any time. In this embodiment, the punching machine 34 is fixed on the platform body 2 and can rotate with it. When a certain punching machine 34 is needed, it only needs to be rotated to the working position, and then the avoidance device 31 pushes the punching machine 34 to slide toward the edge of the platform body 2, so that the blade of the punching machine 34 is located outside the platform body 2, which is convenient for processing the product. When the punching machine 34 slides to the positioning device 33, the positioning device 33 is connected to the punching machine 34, so that the position of the punching machine 34 is fixed to avoid sliding during the processing and ensure the stability of the processing; when the processing is completed, it is necessary to replace other punching machines 34 again, the positioning device 33 is separated from the punching machine 34, the avoidance device 32 pulls the punching machine 34 back, and then the rotary drive device drives the platform body 2 to rotate, rotates the other punching machines 34 to the working position, pushes them out and fixes them, and processes the products; when the punching machine needs to be replaced again, it is only necessary to repeat the above process.

[0038] The rotation drive device includes a driving member and a rotating shaft, the rotating shaft is arranged between the bracket and the platform body 2, and the driving member is connected to the rotating shaft, thereby driving the platform body 2 to rotate. Since the rotation drive device that can drive the platform to rotate is a conventional device, it is not shown in the figure and will not be described here.

[0039] Specifically, in this embodiment, the driving member may be a servo motor, and the platform body 2 is driven by the servo motor to rotate to complete the processing of different products.

[0040] The avoidance device 31 may be a cylinder, one end of which is connected to the punching machine 34 , and the punching machine 34 is driven to slide on the sliding device 32 through the telescopic movement of the cylinder.

[0041] The sliding device 32 may be a slide rail, and correspondingly, a slide groove is provided on the punching machine 34. Through the cooperation between the slide rail and the slide groove, the punching machine 34 can slide freely on the slide rail. Of course, the sliding device 32 may also be in other forms, so that the sliding device 32 is slidably connected to the punching machine 34, and this embodiment does not limit this.

[0042] The positioning device 33 may be a positioning pin cylinder, including a positioning pin and a cylinder body. The positioning pin may be inserted into the piston of the cylinder body to achieve the extension and retraction action. Accordingly, a positioning hole is provided on the punching machine 34. When the punching machine 34 rotates to the working position and is pushed to the positioning device 33, the positioning pin extends under the action of the piston and is inserted into the positioning hole on the punching machine 34, thereby completing the positioning. When the positioning needs to be released, the positioning pin retracts under the action of the piston, so that the punching machine 34 can slide on the sliding device 32 again. Of course, the positioning device 33 may also be in other forms, such as screw fixation, etc., which is not limited in this embodiment.

[0043] In a feasible implementation, the automatic punching and cutting rotating platform of this embodiment also includes a slip ring 21 and a quick-connect connector 22, which are arranged at the center of the platform body 2. The quick-connect connector 22 is connected to the slip ring 21 through a circuit and an air pipe, and the quick-connect connector 22 is connected to the cylinder, positioning pin cylinder, etc. on the punching and cutting unit 3 through a circuit and an air pipe, and is used to supply power and air to the punching and cutting unit 3. By setting the slip ring 21, the connection line and air path of the automatic punching and cutting rotating platform will not affect the rotation of the platform body 2.

[0044] In a feasible implementation, the automatic punching rotary platform of this embodiment further includes a control system, such as a PLC controller (not shown), which can be placed in an independent electrical cabinet box (shown in the figure) located outside the platform, such as Figure 2As shown, the control system is electrically connected to the rotary drive device, the avoidance device 31, the positioning device 33 and the punching machine 34, respectively, and is used to control the actions of these four devices, thereby controlling the rotation of the platform body 2, the sliding and positioning of the punching machine 34, and the punching of the product. Specifically, after the punching work starts, the control system controls the rotary drive device to start, so that it drives the platform body 2 to rotate, and turns the punching machine 34 corresponding to the product to the working position, and then controls the avoidance device 31 to extend, so that the punching machine 34 slides to the positioning device 33, and then controls the positioning device 33 to start, so that it is connected to the punching machine 34, so as to fix the punching machine 34 and position it, and then controls the punching machine 34 to punch the product. After the punching is completed, if the punching machine 34 needs to be replaced, the control system controls the positioning device 33 to disconnect from the punching machine 34, and then controls the avoidance device 31 to retract, and finally controls the rotary drive device to start, drive the platform body 2 to rotate, and turn another punching machine 34 to the working position, and then repeat the above actions. By setting up a control system, automatic control of the automatic punching and cutting rotating platform can be achieved, providing possibility for automatic production of products.

[0045] The number of punching units 3 can be set as required. Preferably, Figure 3 and Figure 4 As shown, it can be set to eight, and the eight punching machines 34 are evenly arranged along the circumference of the platform body 2. If the number of punching machine units 3 is too small, it may not be able to meet the needs of punching various radar holes. If the number is too large, due to the increase in the density of the punching units 3, the product may interfere with the two adjacent non-working punching units 3 during punching. The setting of eight punching units 3 can meet the needs of punching various radar holes as much as possible without affecting normal punching.

[0046] The punching machine 34 in the punching unit 3 can be any existing punching machine, and the present invention does not limit this. The blade shape of each punching machine 34 is different to meet the processing requirements of different products. When the product type changes, the corresponding punching machine 34 only needs to be rotated to the working position to complete the processing.

[0047] Continue to refer to Figure 3 and Figure 4 , the figure shows an automatic punching rotary platform with eight punching units 3, position A is the working position, and a waste bin 4 is provided directly below the working position for holding waste generated during the punching process to prevent the waste from affecting the factory environment and to facilitate the cleaning of the waste.

[0048] In practical applications, the automatic punching and cutting rotating platform of this embodiment is usually used in conjunction with a robot, such as Figure 5As shown, the robot 5 is located at one side of the working position A, and is used to grab the product and move the product to the punching unit 3 of the working position A, so that the punching unit 3 punches the product, and the waste in the punching process falls into the waste bin 4.

[0049] Specifically, the control system of the automatic punching and cutting rotating platform can be arranged in the robot 5. The robot 5 controls the grabbing and moving of the product on the one hand, and controls the movement of the automatic punching and cutting rotating platform on the other hand, thereby realizing automated production and improving production efficiency.

[0050] The automatic punching rotating platform provided in the embodiment of the present invention evenly distributes all the punching units 3 on the platform body 2, and automatically rotates the corresponding punching unit 3 to the working position according to the type of hole to be punched. The robot 5 moves the product and places the position on the product that needs to be punched on the punching unit for punching, thereby achieving the function of being compatible with multiple products, multiple hole shapes and fast switching, and can fully adapt to the current multi-variety, small batch, and fast-paced production rhythm.

[0051] The above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. The above embodiment of the present invention can also be modified in various ways. That is, all simple, equivalent changes and modifications made according to the claims and the description of the present invention fall within the scope of protection of the claims of the present invention.
