Description

Technical Field

[0001] This application relates to the field of automotive trim processing technology, and in particular to an automated processing system and method for upper frame trim strips. Background Technology

[0002] The upper frame trim on automobiles is a decorative protective edge installed on the upper edge of the window; it is a slender, curved strip. Traditional automotive aluminum alloy upper frame trim manufacturing often employs a manual line model. This model involves manual workpiece handling, punching, milling, deburring, edge trimming, laser marking, and end polishing. In a manual line production line, at least six operators are needed to assist with the multiple processes involved in a single product, with a maximum of seven to eight people. This results in high labor costs and an average production cycle of 96 seconds per piece. Clearly, current manufacturing efficiency still heavily relies on manual labor, leading to low productivity and inconsistencies in product dimensions due to varying human operating techniques.

[0017] Exemplary embodiments of the present application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be implemented in various forms and should not be limited to the specific embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present application and to fully convey the scope of the disclosure of the present application to those skilled in the art.

[0018] To fully understand this application, detailed steps and structures will be presented in the following description to illustrate the technical solution of this application. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other implementation methods.

[0019] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0020] See Figures 1-15 This application provides an automated processing system for upper frame trim strips. In addition to processing mechanisms such as a feeding mechanism 10, a punching mechanism 20, a milling mechanism 30, a flanging and trimming mechanism 40, a grinding mechanism 50, and a unloading mechanism 60, it also includes a first transport robot 71, a second transport robot 72, a third transport robot 73, a first transfer fixture 81, and a second transfer fixture 82. The feeding mechanism 10, the punching mechanism 20, and the first transfer fixture 81 are arranged clockwise around the first transport robot 71. The first transport robot 71 is fixedly installed and used to move the upper frame trim strip 93 sequentially between the feeding mechanism 10, the punching mechanism 20, and the first transfer fixture 81. The first transfer fixture 81 and the second transfer fixture 82 are arranged side by side on one side of the second transport robot 72, and the milling mechanism 30 is arranged on the other side of the second transport robot 72. The second transport robot 72 is used to move the upper frame trim 93 sequentially between the first transfer fixture 81, the milling mechanism 30 and the second transfer fixture 82. The second transfer fixture 82, the flanging and trimming mechanism 40, the grinding mechanism 50 and the unloading mechanism 60 are arranged clockwise around the third transport robot 73. The third transport robot 73 is fixedly arranged and is used to move the upper frame trim 93 sequentially between the second transfer fixture 82, the flanging and trimming mechanism 40, the grinding mechanism 50 and the unloading mechanism 60.

[0021] like Figure 1 As shown, in this embodiment, the first handling robot 71, the second handling robot 72, and the third handling robot 73 can all be KUKA robots. The KUKA robots will transport the upper frame trim 93 between different processes. For the core processes of the upper frame trim 93, such as punching, milling, edge flanging and trimming, and grinding, a first transfer fixture 81 and a second transfer fixture 82 are respectively set between the punching process and the milling process, and between the milling process and the edge flanging and trimming process. The first transfer fixture 81 and the second transfer fixture 82 serve as the separators between the first handling robot 71, the second handling robot 72, and the third handling robot 73.

[0022] For miniaturization and integration, the feeding mechanism 10, punching mechanism 20, and first transfer fixture 81 are distributed on the front, left, and rear sides of the first handling robot 71; the second transfer fixture 82 and unloading mechanism 60 are distributed on the rear and front sides of the third handling robot 73; and the flanging and trimming mechanism 40 and grinding mechanism 50 are distributed on the right side of the third handling robot 73. The flanging and trimming mechanism 40 is close to the second transfer fixture 82, and the grinding mechanism 50 is close to the unloading mechanism 60. The flanging and trimming mechanism 40 is angled. The third handling robot 73 is located on the right side of the first handling robot 71. On the right side, the loading mechanism 10 and the unloading mechanism 60 are distributed on the same side, and the first transfer fixture 81 and the second transfer fixture 82 are arranged side by side on the front side of the second handling robot 72, and the milling mechanism 30 is arranged on the rear side. This layout allows for a compact arrangement of the various processing mechanisms in the production line, which is conducive to the miniaturization and integration design of the automated processing production system for the upper frame trim. At the same time, the embodiments of this application use handling robots to automatically connect multiple processes, effectively improving production efficiency. Moreover, the operation of handling robots is more controllable than manual operation, ensuring the stability of the upper frame trim 93 product after processing.

[0023] The processing of the upper frame trim 93 also involves air blowing, deburring, and coding processes. In some embodiments, the processing system further includes a deburring mechanism 91 and a coding mechanism 92, which are arranged clockwise around the third handling robot 73 and located between the unloading mechanism 60 and the second transfer fixture 82. The unloading mechanism 60, the second transfer fixture 82, the coding mechanism 92, and the grinding mechanism 50 are respectively distributed around the front, back, left, and right sides of the third handling robot 73. The deburring mechanism 91 is located between the second transfer fixture 82 and the coding mechanism 92, and the edge-trimming mechanism 40 is located between the second transfer fixture 82 and the grinding mechanism 50. The deburring mechanism 91 and the coding mechanism 92 can be any existing technology, and will not be described in detail here. The deburring mechanism 91 and the marking mechanism 92 have corresponding deburring and marking stations. When the third handling robot 73 clamps the upper frame trim strip and places it at the deburring or marking station, the deburring mechanism 91 or the marking mechanism 92 performs deburring or marking on the upper frame trim strip 93. In these processing steps, the third handling robot 73 does not need to add a clamp to the corresponding mechanism to clamp the upper frame trim strip 93. The marking mechanism 92 is located on the left side of the third handling robot 73, and the deburring mechanism 91 is located between the marking mechanism 92 and the second transfer clamp 82 to adapt to the sequence of the forward and backward movement of the third handling robot 73 within its stroke range. This can improve the turnover rate of the upper frame trim strip 93 in automated processing and production, thereby increasing the production cycle.

[0024] In at least one embodiment, the flanging and trimming mechanism 40 integrates an air blowing function, which can clean the aluminum shavings and other debris covering the end of the upper frame trim 93 after the trimming process is completed at the trimming station, without the need for additional space to arrange the air blowing mechanism.

[0025] In at least one embodiment, an air blowing mechanism may also be included. The air blowing mechanism and the milling mechanism 30 are located together. After the second transport robot 72 removes the upper frame trim 93 from the milling mechanism 30, it carries the upper frame trim 93 to the air blowing station corresponding to the air blowing mechanism. The second transport robot 72 clamps the upper frame trim 93, and the air blowing mechanism blows air onto the upper frame trim 93 to clean and remove debris and particles generated after the milling process. After blowing, the second transport robot 72 moves the upper frame trim 93 to the second transfer fixture 82 for buffering.

[0026] like Figure 1 As shown, in some embodiments, it further includes: a ground rail 74 on which a second transport robot 72 is slidably connected; multiple milling mechanisms 30 are arranged side by side on one side of the ground rail 74, and a first transfer fixture 81 and a second transfer fixture 82 are arranged side by side on the other side; the second transport robot 72 can slide back and forth between the multiple milling mechanisms 30 and between the first transfer fixture 81 and the second transfer fixture 82; the ground rail 74 and the first transport robot 71 are arranged on both sides of the first transfer fixture 81; and the ground rail 74 and the third transport robot 73 are arranged on both sides of the second transfer fixture 82. To improve production cycle time, multiple milling mechanisms 30 can be set up, such as two milling mechanisms 30 arranged side by side. The travel range of a single second handling robot 72 may not be sufficient to cover all these areas. This can be achieved by setting up a linear ground rail 74 and mounting the second handling robot 72 on it. The second handling robot 72 can then reciprocate along the linear ground rail 74, thus extending its travel range and enabling it to slide back and forth between the multiple milling mechanisms 30 and between the first and second transfer fixtures 81 and 82. Alternatively, if the processing mechanisms around the first and third handling robots 71 and 73 are distributed around them, the first and third handling robots 71 and 73 do not require the use of a ground rail 74 to extend their travel range; they can be fixed in place and their travel range can be extended by the movement of their robotic arms.

[0027] like Figure 2As shown, generally speaking, a car has a left window and a right window. The upper frame trim strips 93 corresponding to the left and right windows are symmetrical to each other, but their curvatures are different and not exactly the same. In some embodiments, the first handling robot 71, the second handling robot 72, and the third handling robot 73 all include a multi-axis robotic arm 75 and a mechanical gripper 76 detachably connected to the multi-axis robotic arm 75. The mechanical gripper 76 includes two sets of symmetrically distributed grippers 77. One set of grippers 77 is used to grip the left upper frame trim strip 93, and the other set of grippers 77 is used to grip the right upper frame trim strip 93. To ensure that the mechanical gripper 76 can stably hold the upper frame trim 93, a set of grippers 77 is typically used to grip a single upper frame trim 93. A set of grippers 77 consists of three grippers 77 distributed along the length of the upper frame trim 93. However, when the mechanical gripper 76 has only one set of grippers 77, it can only grip the left upper frame trim 93. Considering the different bending direction of the left upper frame trim 93, it cannot grip the right upper frame trim 93. To reduce the need to disassemble the multi-axis robotic arm and the mechanical gripper 76, two sets of grippers 77 can be integrated into the mechanical gripper 76, each set gripping one side of the upper frame trim 93. This eliminates the need to disassemble and replace the mechanical gripper 76, further improving the production cycle time of the upper frame trim 93.

[0028] like Figure 3 As shown, further, in the third handling robot 73, the mechanical gripper 76 also includes a third set of grippers 77, the third set of grippers 77 is located between two symmetrically distributed sets of grippers 77, and the unloading mechanism 60 includes a partition 66 for separating the upper frame trim 93 vertically, and the third set of grippers 77 is used to grip the partition 66. In addition to transferring components during deburring, marking, flanging, trimming, and polishing processes, the third handling robot 73 also needs to place the processed upper frame trim strips 93 into the unloading mechanism 60. To increase the number of upper frame trim strips 93 stored in the unloading mechanism 60, a partition 66 can be provided to the unloading mechanism 60 to allow the upper frame trim strips 93 to be stacked vertically within the unloading mechanism 60. However, the upper frame trim strips 93 on the partition 66 are not initially placed in the unloading mechanism 60 to form a storage platform. Therefore, the partition 66 needs to be set up to form a storage platform. Thus, the grippers 77 that move the partition 66 can be integrated into the third handling robot 73, reducing the need for additional handling mechanisms. Specifically, a set of grippers 77 for gripping the partition 66 is placed between two sets of grippers 77 for gripping the upper frame trim strips 93. Since the partition 66 is straight, two grippers 77 can be used as a set to handle the partition 66.

[0029] like Figure 4 and Figure 5As shown, the first transfer clamp 81 and the second transfer clamp 82 have the same structure. Taking the first transfer clamp 81 as an example, the first transfer clamp 81 includes a base plate 83 and two sets of clamping components 84 disposed on the base plate 83. Each set of clamping components 84 is used to clamp different upper frame trim strips 93. Among them, one set of clamping components 84 includes three clamping components 84, left, center and right. The distribution of the three clamping components 84 is adapted to the distribution of the upper frame trim strips 93. Each clamping component... 84 includes a bracket 85, a clamping jaw 86, a clamping cylinder, and a supporting jaw 87. The supporting jaw 87 and the clamping cylinder are fixed on the bracket 85. The clamping jaw 86 is movably mounted on the bracket 85 and connected to the clamping cylinder. The clamping cylinder is used to drive the clamping jaw 86 to clamp the upper frame trim 93. The supporting jaw 87 is located on one side of the clamping jaw 86, serving as a guide for the workpiece and providing support for the upper frame trim 93, so that the clamping jaw 86 can clamp the upper frame trim 93.

[0030] like Figures 6-9 As shown, in some embodiments, the feeding mechanism 10 includes: Two material platforms 11 are distributed vertically, and both material platforms 11 are driven by electric cylinders to reciprocate between their respective feeding station 12 and picking station 13. Multiple sets of feeding fixtures 14 are provided on each material platform 11. The multiple sets of feeding fixtures 14 are arranged at intervals along the moving direction of the material platform 11. The feeding fixtures 14 include error-proof positioning components 141, clamping positioning components 142 and at least one support component 143 that are sequentially and at intervals along the length direction of a single upper frame trim strip 93. The anti-misalignment positioning component 141 includes an anti-misalignment platform 1411 and an anti-misalignment block 1412. The anti-misalignment platform 1411 has an anti-misalignment groove 1413 for receiving the upper frame trim strip 93. The anti-misalignment block 1412 is disposed on the anti-misalignment platform 1411 and partially extends into the anti-misalignment groove 1413 for fitting into the notch 930 on the upper frame trim strip 93. The clamping and positioning assembly 142 includes a clamping table 1421 and a clamping block 1422. The clamping table 1421 has a clamping groove 1423 for receiving the upper frame trim strip. The clamping block 1422 is located on one side of the clamping groove 1423 and is used to move away from the clamping groove 1423 under the action of elastic force, so as to clamp the upper frame trim strip 93 into the clamping groove 1423.

[0031] in, Figure 6 and Figure 8As shown, the feeding mechanism 10 differs from the rotary feeding mechanism in that it adopts a stacked structure, making full use of vertical height, so that the feeding mechanism 10 in this embodiment occupies less floor space than the rotary feeding mechanism. The two layers of feeding platforms 11 are of different heights and are distributed one in front of the other along the feeding station 12 and the picking station 13. The feeding platforms 11 can be driven by electric cylinders to achieve linear reciprocating motion. When feeding is needed, the electric cylinder can drive the upper feeding platform to move the feeding fixture 14 to the feeding station 12. According to the error-proof design of the feeding fixture 14, the operator places the upper frame trim 93 onto the appropriate feeding fixture 14. After all the material is loaded onto the upper feeding fixture 14, the feeding platform 11 is moved to the picking station 13 for the first handling robot 71 to grasp. Similarly, the lower feeding platform 11 is moved to the feeding station 12, and the upper and lower feeding layers are alternately loaded in a cyclical manner. Furthermore, the movement speed of the electric cylinder can be adapted to the product cycle of different upper frame trims, and can ensure high precision of repeatable positioning within the electric cylinder stroke, thereby ensuring the stability of the first handling robot 71 when picking up materials.

[0032] The clamping block 1422 includes a clamping movable block 14220, which is embedded in the clamping block 1422 and connected to the clamping block 1422 via a spring. When the upper frame trim 93 is located in the clamping groove 1423, the clamping movable block 14220 is received in the clamping block 1422 under the elastic force of the spring and the pushing force of the upper frame trim 93. At this time, the upper frame trim 93 is subjected to the clamping force of the clamping movable block 14220, so that it can be stably clamped in the clamping positioning assembly 142.

[0033] In addition, each loading fixture also includes a sensor 144, which is used to detect whether the upper frame trim 93 is present in the loading fixture.

[0034] Considering that the upper frame trim 93 has left and right sides, the distribution of punched holes on the different upper frame trim 93 will naturally differ. Two sets of punching components 21 can be set on the punching mechanism 20: one set for punching the left upper frame trim 93, and the other set for punching the right upper frame trim 93. For example... Figure 10As shown, taking a punching assembly 21 as an example, the punching assembly 21 includes a base plate 22 and a plurality of punching units 23 disposed on the base plate 22. The plurality of punching units 23 are distributed on the base plate 22 to fit the upper frame trim 93. Each punching unit 23 is used to punch holes such as circular holes or waist-shaped holes at specific positions on the upper frame trim 93. The type of hole can be determined according to the type of tool. In a punching unit 23, there is a mounting base 24 and a lower contour block 25, a punching tool 26, an upper contour block 27 and a punching cylinder 28 mounted on the mounting base 24. The lower contour block 25 and the punching cylinder 28 are fixedly disposed with the mounting base 24. The punching tool 26 is mounted on the upper contour block 27, and the upper contour block 27 moves closer to or away from the lower contour block 25 under the action of the punching cylinder 28 via a slide rail assembled on the mounting base 24. When the punching cylinder 28 extends downward, the upper contour block 27 drives the punching cutter 26 to move toward the lower contour block 25 to punch the upper frame trim 93 on the lower contour block 25.

[0035] In at least one embodiment, the milling mechanism 30 is used to mill the punched upper frame trim 93. The milling mechanism 30 is provided with a milling fixture, which holds the upper frame trim 93. The milling mechanism 30 mills the held upper frame trim 93. The milling mechanism 30 can be a milling mechanism known to those skilled in the art, and will not be described in detail here.

[0036] like Figure 11As shown, in some embodiments, the flanging and trimming mechanism 40 includes at least two flanging components 41 and at least two trimming components 42, which are staggered. The third handling robot 73 is used to move the flanged upper frame trim 93 to the corresponding trimming component 42, so that the trimming component 42 can clamp and trim the flanged upper frame trim 93. The flanging and trimming mechanism 40 includes a large base plate 83 and two flanging components 41 and two trimming components 42 disposed on the large base plate 83. The flanging components 41 and trimming components 42 are combined in pairs to process the left and right upper frame trims 93. That is, one flanging component 41 and one trimming component 42 are used to process upper frame trims 93 of the same specification, and the flanging component 41 and trimming component 42 processing the same upper frame trim 93 are arranged adjacent to each other. The flange assembly 41 includes a flange support molding block 411, a flange pressing molding block 412, a flange drive cylinder 413, and a flange block 414. The upper frame trim 93 is gripped by the third handling robot 73 and extends between the flange pressing block and the flange support block. The flange drive cylinder 413 extends downward to drive the flange block 414 to flange the end of the upper frame trim 93. The flange support block is provided with a limiting block 415 on the side near the third handling robot 73 to secure the upper frame trim 93 in the flange assembly. The trimming assembly 42 includes a trimming support contour block 421, a trimming pressing contour block 422, a pressing drive cylinder 423, a transmission block 424, a transmission connecting rod 425, and a cutter 426. The trimming pressing contour block 422 and the trimming support contour block 421 are arranged vertically. The top of the trimming pressing contour block 422 is connected to the pressing drive cylinder 423. Considering that the end of the upper frame trim strip 93 after flanging has a certain height when entering the trimming assembly 42, it can be... The overpressure material drive cylinder 423 adjusts the distance between the trimming pressing material shaping block 422 and the trimming support shaping block 421 to clamp the flanged upper frame trim strip 93 therein. The cutter 426 is connected to the transmission block 424 through the transmission link 425. The transmission block 424 moves under the drive of the cutter 426 drive cylinder and transmits power to the cutter 426 through the transmission link 425 so that the cutter 426 can cut off the end waste of the upper frame trim strip 93.

[0037] like Figure 12 As shown, in some embodiments, the processing system further includes a grinding chamber 51, a grinding mechanism 50 disposed in the grinding chamber 51, the grinding chamber 51 including a window having a closed state and an open state, the window being used for the third handling robot 73 to move the upper frame trim 93 into the grinding chamber 51 when in the open state; wherein, the grinding mechanism 50 includes a grinding fixture 52 and a grinding robot 53, the grinding fixture 52 being disposed near the window, the grinding robot 53 including a robotic arm, a frame 531 detachably connected to the robotic arm, a grinding fixture 532 mounted on one side of the frame 531, and a polishing fixture 533 mounted on the other side of the frame 531.

[0038] The grinding robot 53 generates a large amount of dust during operation. A window design prevents dust from overflowing from the grinding chamber 51. This window can be implemented as a roller shutter door. Furthermore, the frame 531 integrates a grinding fixture 532 and a polishing fixture 533. The grinding fixture 532 includes a floating force control device 5321 and a grinding head 5322. The grinding head 5322 has a 3-inch grinding disc. The grinding pressure can be set via a touchscreen. The grinding area can be selected according to requirements, such as the edge after flanging and surface A. The grinding head 5322 contacts the surface of the upper frame trim 93 at high speed. Rotational kinetic energy is converted into linear motion to polish the surface of the upper frame trim 93. The number of pieces polished per piece can be set on the touchscreen. Once the set value is reached, the sandpaper is replaced to ensure polishing quality. The polishing fixture 533 includes a cloth wheel 5331 and a spray gun 5332. The cloth wheel 5331, with abrasive on its surface, cuts or plastically deforms the upper frame trim 93, removing protrusions to achieve a smooth surface. The load fed back from the rotation of the cloth wheel 5331 during polishing is converted into a corresponding current to determine whether compensation is needed. The polishing robot 53 can detect the current during polishing and compensate in the normal direction based on the comparison between the detected current and a set current threshold to ensure normal polishing pressure. Simultaneously, the spray gun 5332 is oriented towards the cloth wheel to ensure stable spray supply during polishing of the upper frame trim 93. Furthermore, an industrial vacuum cleaner can be used to vacuum the area around the polishing disc via a corrugated pipe.

[0039] The structure of the grinding fixture 52 is the same as that of the first transfer fixture 81, and will not be described in detail here.

[0040] like Figures 13-15 As shown, in some embodiments, the feeding mechanism 60 includes: The material feeding frame 61 includes multiple partitions 66 and multiple sets of vertically distributed support rods 65. Each set of support rods 65 is used to place at least two partitions 66, and at least two partitions 66 are used to divide the upper frame trim strip 93 vertically. The material feeding bracket 62 includes a vertically arranged back plate that divides the material feeding bracket 62 into two support platforms, each support platform for placing the material feeding frame 61. The unloading drive assembly 63 is connected to the unloading bracket 62 and is used to drive the corresponding support platform toward the third handling robot 73.

[0041] In the unloading mechanism 60, there are two unloading brackets 62, which are set back to back by a vertical plate 621, which is the aforementioned back plate. The bottom of the unloading bracket 62 is provided with a rotary driver, which can be used to drive the unloading bracket 62 to switch from facing the third handling robot 73 to facing away from the third handling robot 73, and vice versa, for replacing the unloading frame 61 on the unloading bracket 62. The unloading frame 61 includes two side frames 64, and the side frames 64 are provided with at least two sets of multiple vertically distributed support rods 65. The two front and rear support rods 65 are used to place a spacer 66. The two sets of support rods 65 correspond to two spacers 66. The two spacers 66 at the same height provide a supporting plane for the upper frame trim 93. The spacers 66 are used to isolate each layer of upper frame trim 93 to prevent the upper frame trim 93 from being bumped or damaged. The spacers 66 are placed on a spacer frame 67, which is located on one side of the unloading mechanism 60 and is used to store the spacers 66. The rotary driver is a drive motor, which drives the two unloading brackets 62 to rotate together. The unloading brackets 62 drive the unloading frame 61 to rotate in order to realize the unloading process of the upper frame trim 93.

[0042] As can be seen, the present application embodiment, by combining three handling robots and two transfer fixtures with the corresponding processing mechanism, can not only achieve system equipment integration and miniaturization, effectively reduce the system footprint, but also effectively improve production efficiency, with a production cycle of 30s / PCS for a single product.

[0043] This application embodiment also provides an automated processing method for upper frame trim strips, applied to the above-mentioned automated processing system for upper frame trim strips, mainly including steps S001 to S005.

[0044] S001: After determining that the upper frame trim is located at the material handling station of the feeding mechanism, the first handling robot moves the upper frame trim to the punching mechanism, the punching mechanism clamps the upper frame trim and performs corresponding punching processing on the upper frame trim; S002: In response to the punching completion signal, the first handling robot moves the punched upper frame trim to the first transfer fixture; S003: In response to the trigger signal generated by the first transfer fixture, the second handling robot moves the corresponding upper frame trim to the milling mechanism, and the milling mechanism clamps the upper frame trim and performs milling processing on the upper frame trim. S004: In response to the milling completion signal, the second handling robot moves the milled upper frame trim to the second transfer fixture; S005: In response to the trigger signal generated by the second transfer fixture, the third handling robot moves the corresponding upper frame trim to the flanging and trimming mechanism and the polishing mechanism in sequence, and moves the polished upper frame trim to the unloading mechanism.

[0045] In this embodiment, both the stamping mechanism and the flanging and trimming mechanism are equipped with corresponding contour blocks to clamp the upper frame trim. The milling mechanism and the grinding mechanism are equipped with corresponding fixtures. When the transport robot moves the upper frame trim to the corresponding processing mechanism, the corresponding processing mechanism clamps the upper frame trim and starts the corresponding process. After the corresponding processing process is completed, an end signal can be issued. According to the issued end signal, the transport robot can take away the upper frame trim and move it to the next processing mechanism for the corresponding process, thereby realizing the automation of the upper frame trim processing production line.

[0046] The automated processing system for the upper frame trim also involves deburring and coding processes. The third transport robot clamps the upper frame trim and places it at the deburring or coding station. The deburring or coding mechanism performs deburring or coding on the upper frame trim. Depending on the spatial position of the processing mechanism, the deburring and coding mechanisms can be positioned close to the left side of the third transport robot. Specifically, the coding mechanism is located on the left side of the third transport robot, and the deburring mechanism is located between the second transfer fixture and the coding mechanism.

[0047] It should be noted that the various mechanisms in the method embodiments have been described in detail in the above-described processing and production system embodiments, and therefore will not be repeated here.

[0048] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations included in the claims. Various modifications and changes can be made to the above embodiments without departing from the scope of this disclosure. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of this application that may not be explicitly described. Therefore, the above embodiments only illustrate several implementations of this application and do not limit the scope of protection of this patent application.
