Description

TECHNICAL FIELD

[0001] The application relates to the field of production and processing of automobile parts, and particularly relates to a complete automatic punching equipment for sealing strips. BACKGROUND

[0002] The automobile sealing strip can also be called a protective profile, and the main material is polyvinyl chloride. The automobile sealing strip is formed by extrusion through related equipment and is finally formed through multi-step stamping after processing. The automobile sealing strip is used for door frames, side windows and front and rear windshields of automobiles. The automobile sealing strip can not only play a sealing role but also play a vibration reduction role. The automobile sealing strip is an important part of automobile body design, and the quality of the automobile sealing strip directly affects the quality of the automobile.

[0003] The main process of the automobile sealing strip after processing includes multi-step stamping. In the existing automobile sealing strip processing scheme, small batches generally adopt the method of manually inserting the to-be-processed sealing strip into each stamping station in sequence. This processing method requires workers to have certain operation proficiency and has high labor cost. Large batches generally adopt special semi-automatic or full-automatic post-processing production lines. The special post-processing production line, especially the full-automatic production line, adopts a processing method of large-scale conveying system and two-side hydraulic system to push the stamping tooling, which has good stability and high production efficiency.

[0004] A related patent, namely, an automobile sealing strip punching machine (application number: CN202220474093.1), discloses that the upper and lower surfaces of the automobile sealing strip are smooth surfaces, and the automobile sealing strip punching machine comprises a rack, a clamping groove for placing the automobile sealing strip is arranged on the rack, and a blanking hole is formed at the two ends of the clamping groove. A linear driving mechanism is installed above the clamping groove on the rack, the lower end of the linear driving mechanism is in transmission connection with a bearing plate, the bearing plate is driven by the linear driving mechanism to displace in the vertical direction. The sealing strip can be fixed by pressing the sealing strip through the pressing plate during punching, so that the sealing strip is not easy to bend and is convenient for punching. In addition, the adsorption hole formed in the bottom surface of the movable pressing plate can adsorb the sealing strip placed in the clamping groove after punching, so that the sealing strip is convenient to take, and the whole operation is more convenient and fast.

[0005] For example, Chinese patent application "An automatic punching production line for automobile door and window frame sealing strip", application number: CN201810886017.X; disclosed including length detection device, rolling device and end cap assembly tool, from left to right in turn length detection device, rolling device and end cap assembly tool, the left side of the length detection device is installed with the first robot, the rear of the first robot is installed with the punch and the punching die matched with the punch, the left side of the rolling device is installed with the second robot, the rear of the second robot is installed with the fixed length cutting device, the left side of the end cap assembly tool is installed with the third robot, and the rear of the third robot is installed with the end cap visual screening mechanism. The application is convenient to use, has low equipment cost, high automation degree, and greatly reduces the labor cost.

[0006] The sealing strip punching equipment in the prior art is designed for punching a certain type of sealing strip structure. However, for an automobile, the installation of the doors of an automobile involves a complete set of sealing strips with different structures. Therefore, the traditional processing method is to process different sealing strip structures on different assembly lines, and then pack them into a complete set of sealing strip components and send them to the assembly end of the automobile. In view of the above problem, the present application designs an automatic punching equipment for a complete set of sealing strips, which can punch and process different types of sealing strips in one punching equipment. SUMMARY

[0007] The technical problem to be solved by the present application is to provide an automatic punching equipment for a complete set of sealing strips, which can match different punching tools for processing different types of sealing strips, and can realize the punching process of a complete set of sealing strips with different structures.

[0008] The technical scheme adopted by the present application is: an automatic punching equipment for a complete set of sealing strips, comprising a rack, and an upper feeding device, a conveying device, a lower discharging device and a plurality of punching stations installed on the rack, the punching stations are detachably installed with punching tools, the punching tools on the rack are not the same, and sealing strips with different structures are matched with installation clamps with different type identification codes, the punching stations are provided with readers for reading the identification codes, and the installation clamps pass through the punching stations under the driving of the conveying device; when the installation clamps reach the punching stations, the readers on the punching stations read the identification codes on the installation clamps and judge whether the sealing strips on the installation clamps need to be processed in the punching stations, if the judgment is that the sealing strips need to be processed, the punching tools of the punching stations work to process the sealing strips on the installation clamps, and if the judgment is that the sealing strips do not need to be processed, the installation clamps directly pass through the punching stations.

[0009] Compared with the prior art, the application has the advantages that: firstly, a cutting station of a pipeline type is arranged, and cutting tools are detachably arranged on the cutting station, which increases the flexibility and possibility of the cutting device, and the cutting tools can be arranged according to actual processing requirements. Secondly, for the cutting device capable of forming a complete sealing strip, the cutting tools arranged on the entire device are necessarily different, and the sealing strips of different structures are processed.

[0010] The design idea of the application is to collect all the cutting tools required by a set of sealing strips, and the sealing strips pass through each cutting station in turn and are selectively cut at the required cutting station. For this purpose, the application matches different types of identification codes for sealing strips of different structures. A reader is designed on the cutting station, which is used to identify the identification code on the mounting clamp reaching the cutting station, and to determine whether the sealing strip needs to be processed at this position according to the identification code. The selective processing of the sealing strip at the cutting tool is realized. After the sealing strip passes through the preset cutting stations, the sealing strip has completed the cutting process.

[0011] The application enables sealing strips of different structures to be processed by the same cutting device, which is very suitable for processing complete sealing strips of automobiles, and facilitates subsequent packaging and delivery of the complete sealing strips of automobiles to the automobile assembly end. The application also realizes the integration of the cutting device, and the processing plant no longer needs to place multiple cutting devices, but can directly use the application to process.

[0012] In some embodiments of the application, sealing strips of the same structure correspond to the same type of sealing strip, and sealing strips of different structures correspond to different types of identification codes; sealing strips of different structures match mounting clamps of different structures, and the structure of the mounting clamp, the type of the identification code, and the structure of the sealing strip correspond one-to-one.

[0013] Generally, the mounting clamps matched by sealing strips of different structures are different, and it is not excluded that some mounting clamps can match two or more sealing strips of different structures. Of course, the mounting clamps corresponding to sealing strips of the same structure are the same, and the identification code type on the mounting clamps of sealing strips of the same structure is also the same.

[0014] In some embodiments of the application, the identification code is an ID card and an identifying word or pattern.

[0015] The application further optimizes the processing steps of the sealing strip:

[0016] In some embodiments of the present application, the conveying device comprises at least two processing tracks arranged in parallel in the vertical plane, and punching stations are arranged on both sides of the processing tracks. The above is the preferred scheme of the present application. Considering that too many punching stations are used, if a single processing line is arranged, the automatic punching equipment of the present application has a large floor area. Therefore, in terms of floor area and molding difficulty of the equipment, it is most reasonable to arrange 2-3 processing lines in the vertical direction.

[0017] In some embodiments of the present application, the feeding device comprises a door-shaped track frame and a feeding base, a vertical straight track is arranged on the track frame, the feeding base is installed on the straight track, and the feeding base moves up and down along the straight track under the driving of a power device to dock different processing tracks; a horizontal track for docking with the processing tracks is arranged on the feeding base, and readers are installed on both sides of the horizontal track. The readers identify the mounting clamps on the horizontal track and then control the feeding base to dock one of the processing tracks.

[0018] The design idea of the present application is that, in order to reduce unnecessary reading and identification of codes on the punching stations, at the initial assembly of the punching tooling of the punching stations, the punching tooling for processing the sealing strips of the same structure is arranged on both sides of the same processing track. Therefore, in the actual processing of the sealing strips, it is not necessary to pass through each processing station, but only one processing track is needed to complete all the processing and then output by the discharging device. This design of the present application can save at least half of the passing time of the punching stations, and improves the processing efficiency.

[0019] In the present application, the feeding device can be connected to manual operation, that is, the mounting clamps with the sealing strips are placed on the feeding base of the feeding device by manual operation. The feeding device can also be connected to other equipment to complete the assembly of the sealing strips in the mounting clamps.

[0020] In some embodiments of the present application, the discharging device comprises a door-shaped track frame and a discharging base, a vertical straight track is arranged on the track frame, and the discharging base is installed on the straight track. The discharging base moves up and down along the straight track under the driving of a power device to dock different processing tracks, and discharges the processed sealing strips out of the rack.

[0021] Specifically, the discharging base in the present application can be connected to manual operation for discharging, or can be connected to other equipment to guide the punched sealing strips to the next processing, packaging and assembly process. Specifically, the discharging base can also be provided with a reader for classifying and outputting the sealing strips.

[0022] In some embodiments of the present application, the cutting station is provided with a transverse track, and the reader is mounted on the transverse track and can move along the transverse track.

[0023] The cutting station is provided with a movable reader, which can adapt to different structures of the sealing strip mounting clamp and ensure that the reader can read the identification code on the mounting clamp.

[0024] In some embodiments of the present application, the conveying device comprises a waste conveying track corresponding to each processing track, the waste conveying track is located below the corresponding processing track, the rack is a frame structure, and the waste generated by cutting falls to the waste conveying track under the action of gravity.

[0025] In some embodiments of the present application, a waste conveying elevator is arranged between the output end of the waste conveying track and the discharging device, the waste conveying elevator is located below the waste conveying track, the waste conveying elevator is connected to the mobile tool vehicle, the waste conveying elevator comprises a conveying belt, one end of the conveying belt is located below the output end of the waste conveying track, the other end of the conveying belt is located above the mobile tool vehicle, and the waste falls to the conveying belt and is guided into the mobile tool vehicle by the conveying belt.

[0026] In some embodiments of the present application, the rack is provided with a plurality of transverse moving tracks, the cutting station is mounted on the transverse moving tracks, and the cutting station moves to approach the sealing strip or does not move after the reader at the cutting station determines whether the cutting tool is working.

[0027] On the basis of common knowledge in the art, the above-mentioned embodiments can be combined arbitrarily. BRIEF DESCRIPTION OF DRAWINGS

[0035] The present application will now be described in detail with reference to the accompanying drawings.

[0036] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0037] An automatic punching and cutting equipment for sealing strips, as described in Embodiment 1 Figures 1 to 3 As shown, the device includes a frame 1, and a feeding device 2, a conveying device, a discharging device 4, and multiple punching stations 5 mounted on the frame 1. Each punching station 5 is detachably equipped with punching fixtures. The punching fixtures on the frame 1 are not identical, adding more flexibility and possibilities to the punching equipment of this application. The punching fixtures can be arranged according to actual processing needs. For punching equipment capable of producing complete sets of sealing strips, the punching fixtures arranged on the entire equipment will inevitably differ, processing sealing strips with different structures.

[0038] The design concept of this application is to integrate all the punching fixtures required for a set of sealing strips. The sealing strip passes through each punching station 5 sequentially, selectively undergoing punching processing at the required punching stations 5. Sealing strips of different structures are matched with mounting fixtures bearing different model identification codes. Each punching station 5 is equipped with a reader 7 for reading the identification code. The mounting fixture passes through the punching station 5 under the drive of the conveying device. When the mounting fixture reaches the punching station 5, the reader 7 at the punching station 5 reads the identification code on the mounting fixture and determines whether the sealing strip on the mounting fixture needs to be processed at that punching station 5. If it is determined that it is needed, the punching fixture at that punching station 5 processes the sealing strip on the mounting fixture; if it is determined that it is not needed, the mounting fixture directly passes through the punching station 5. This achieves selective processing of the sealing strip at the punching fixtures. Therefore, after the sealing strip passes through each preset punching station 5, the punching process of the sealing strip is completed.

[0039] This application enables the processing of sealing strips with different structures using the same punching equipment, making it ideal for processing complete sets of automotive sealing strips. This facilitates the subsequent packaging and delivery of complete sets of automotive sealing strips to the vehicle assembly plant. This application also integrates the punching equipment, eliminating the need for multiple punching machines in the processing plant; the single set of equipment described in this application can be used directly for processing.

[0040] Sealing strips with the same structure correspond to the same model of sealing strip, while sealing strips with different structures correspond to different model identification codes; sealing strips with different structures are matched with different structured mounting clamps, and the structure of the mounting clamp, the model of the identification code, and the structure of the sealing strip are in one-to-one correspondence.

[0041] Generally, different types of sealing strips require different mounting clamps, although some mounting clamps may be compatible with two or more different types of sealing strips. Of course, sealing strips of the same type require identical mounting clamps, and the identification code on the mounting clamps for sealing strips of the same type is also the same.

[0042] In this application, the mounting fixture equipped with the sealing strip is not specifically shown, but those skilled in the art should understand that the fixture used to hold the sealing strip is also a conventional structure in the art. The improvement of this application is to add an identification code to the mounting fixture, without making any improvement to its specific structure.

[0043] The identification code is an ID card and identifying text or pattern.

[0044] Example 2, as Figures 1 to 5 As shown, this application further optimizes the processing steps of the sealing strip:

[0045] The conveying device includes at least two processing tracks 31, which are arranged parallel to each other on a vertical plane. Punching stations 5 are provided on both sides of the processing tracks 31. This is a preferred embodiment of the present application. However, considering the large number of punching stations 5, if a single processing line is used, the automatic punching equipment of this application would have a large footprint. Therefore, considering both footprint and the difficulty of forming the equipment, arranging 2-3 processing lines vertically is the most reasonable approach.

[0046] The feeding device 2 comprises a door-shaped track frame 21 and a feeding base 22. The track frame 21 is provided with vertical straight tracks 23. The feeding base 22 is installed on the straight tracks 23 and moves up and down along the straight tracks 23 under the driving of a power device to dock with different processing tracks 31. The feeding base 22 is provided with horizontal tracks 24 for docking with the processing tracks 31. The two sides of the horizontal tracks 24 are provided with readers 7. The readers 7 identify the mounting clamps on the horizontal tracks 24 and control the feeding base 22 to dock with one of the processing tracks 31.

[0047] The design idea of the present application is that, in order to reduce unnecessary reading and identification codes on the punching station 5, the punching tooling for processing the sealing strips of the same structure is arranged on the two sides of the same processing track 31 in the initial assembly of the punching tooling of the punching station 5. Therefore, in the actual processing of the sealing strips, it is not necessary to pass through each processing station. Only one of the processing tracks 31 is needed to complete all the processing and then be guided out by the discharging device 4. The design of the present application can save at least half of the passing time of the punching station 5 and improve the processing efficiency.

[0048] In the present application, the feeding device 2 can be docked with manpower, i.e. the mounting clamps with sealing strips are placed on the feeding base 22 of the feeding device 2 by manpower. The feeding device 2 can also be docked with other equipment to complete the assembly of the sealing strips on the mounting clamps.

[0049] The discharging device 4 comprises a door-shaped track frame 21 and a discharging base 41. The track frame 21 is provided with vertical straight tracks 23. The discharging base 41 is installed on the straight tracks 23 and moves up and down along the straight tracks 23 under the driving of a power device to dock with different processing tracks 31 and guide the processed sealing strips out of the rack 1.

[0050] Specifically, the discharging base 41 in the present application can be docked with manpower for discharging or docked with other equipment to guide the punched sealing strips to the next processing, packaging and assembly process. Specifically, the discharging base 41 can also be provided with readers 7 for classifying and outputting the sealing strips.

[0051] The punching station 5 is correspondingly provided with a transverse track 51. The readers 7 on the punching station 5 are installed on the transverse track 51 and can move along the transverse track 51. The movable readers 7 at the punching station 5 can adapt to sealing strip mounting clamps of different structures and ensure that the readers 7 can read the identification codes on the mounting clamps.

[0052] The frame 1 is provided with multiple transverse tracks 10, and the punching station 5 is installed on the transverse tracks 10. After the reader 7 at the punching station 5 determines whether the punching fixture is working, the punching station 5 will move closer to the sealing strip or not move.

[0053] The conveying device includes a waste conveying track 32 that corresponds one-to-one with the processing track 31. The waste conveying track 32 is located below its corresponding processing track 31. The frame 1 is a frame structure. The waste generated by punching falls onto the waste conveying track 32 under the action of gravity.

[0054] The rest of the contents of Example 2 are the same as those of Example 1.

[0055] Example 3, as Figure 4 , Figure 5 As shown, a waste conveying elevator 8 is provided between the output end of the waste conveying track 32 and the unloading device 4. The waste conveying elevator 8 is located below the waste conveying track 32. The waste conveying elevator 8 is connected to the mobile tool cart 9. The waste conveying elevator 8 includes a conveyor belt. One end of the conveyor belt is located below the output end of the waste conveying track 32, and the other end of the conveyor belt is located above the mobile tool cart 9. After the waste falls onto the conveyor belt, it is guided into the mobile tool cart 9 by the conveyor belt.

[0056] The other contents of Example 3 are the same as those of Example 1 or Example 2.

[0057] It should be noted that the punching fixture is not assembled in the drawings of this application; only the structure of the punching station 5 is shown.

[0058] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
