Description

[0001] This invention is a divisional application of patent application number 202511557862.9, filed on October 29, 2025, entitled "An Automatic Labeling Method and Equipment for Automobile Rear Fender". Technical Field

[0002] This invention relates to the field of automobile rear spoiler manufacturing technology, and in particular to an automatic labeling method for automobile rear spoilers. Background Technology

[0003] Existing technology, such as patent application publication number CN108622493A, discloses a fully automatic labeling machine, including a worktable, a clamping and lifting assembly, a frame protective cover assembly, a robotic arm assembly, and a label peeling assembly. The worktable includes a worktable mounting base plate and a lower conveyor belt. The clamping and lifting assembly is installed at both ends of the worktable mounting base plate. The worktable is provided with a working unit, which includes the frame protective cover. A second fixing plate is provided at the top inside the frame protective cover. The robotic arm assembly is installed on the second fixing plate. The label peeling assembly is installed inside the frame protective cover through the first fixing plate.

[0004] Because the rear spoiler of a car has an arc-shaped structure, existing labeling machines cannot label the rear spoiler and are prone to scratching it. Existing labeling machines use a roll-feeding method for dispensing and recycling release paper, resulting in low production efficiency. Existing labeling machines require multiple motion mechanisms to grip the workpiece, grip the label, press the label, and tear the backing paper, making the structure complex.

[0005] The existing technology has the following problems:

[0006] Existing labeling machines are unable to label car rear spoilers, resulting in low production efficiency and complex structures.

[0007] The above statements are for the purpose of providing background information in relation to this application only and do not necessarily constitute prior art. Summary of the Invention

[0008] Therefore, there is a need to provide an automatic labeling method and equipment for automobile rear spoilers, in order to solve the technical problems of existing labeling machines being unable to label automobile rear spoilers, having low production efficiency, and having complex structures.

[0009] To achieve the above objectives, in a first aspect, the present invention provides an automatic labeling method for automobile rear spoilers, comprising the following steps:

[0010] S101, Remove the rear spoiler of the car;

[0011] The workpiece pallet moves the car rear spoiler to a designated position. The first robotic arm moves the mounting plate above the workpiece pallet. The workpiece suction cup assembly is located at the bottom of the mounting plate in the vertical direction and picks up the car rear spoiler.

[0012] S102, Fixed vehicle rear spoiler;

[0013] The first robotic arm places the car's rear spoiler onto the label pasting fixture, and the first clamping cylinder moves to clamp the car's rear spoiler.

[0014] S103, Extract the first label;

[0015] The first robotic arm moves the mounting plate to above the first label strip placement area. The first robotic arm rotates the mounting plate counterclockwise so that the label suction cup assembly is located at the bottom of the mounting plate in the vertical direction, and the workpiece suction cup assembly is located at the top of the mounting plate in the vertical direction. The label suction cup assembly picks up the first label strip, and the first robotic arm moves the first label strip to the release paper tearing mechanism. The release paper tearing mechanism clamps the release paper of the first label strip, and the first robotic arm moves to tear off the release paper of the first label strip.

[0016] S104. Attach the first label strip to the rear spoiler of the car;

[0017] The first robotic arm moves to stick the first label strip to the upper surface of the car's rear spoiler. The pressing cylinder and the label tearing cylinder are located on the same side of the label suction cup assembly on the mounting plate. The pressing cylinder moves to press the first label strip firmly, and the label tearing cylinder moves to tear off the back paper of the first label strip.

[0018] S105. Check whether the first label strip is properly affixed;

[0019] The camera detects whether the first label is properly affixed. If the first label is properly affixed, the first clamping cylinder moves to release the car rear spoiler. The first robotic arm rotates the mounting plate clockwise so that the workpiece suction cup assembly is located at the bottom of the mounting plate in the vertical direction. The three-axis gripping mechanism transports the car rear spoiler to the next workstation.

[0020] Unlike existing technologies, the above technical solution uses a workpiece suction cup assembly to pick up a car rear spoiler, a label pasting fixture to fix the spoiler, a label suction cup assembly to pick up a first label strip, a release paper tearing mechanism to tear the release paper off the first label strip, a pressing cylinder to press the first label strip firmly, and a label tearing cylinder to tear off the backing paper of the first label strip. This allows for labeling the upper surface of the car rear spoiler, and the label pasting fixture can fix the spoiler, preventing scratches. The label suction cup assembly can pick up a long label strip at once, and the release paper tearing mechanism can tear off the release paper in one go, eliminating the need to wait for the unwinding and rewinding of the feed roll, thus improving production efficiency. By placing the workpiece suction cup assembly at one end of the mounting plate, and the label suction cup assembly, pressing cylinder, and label tearing cylinder at the other end, multiple motion mechanisms are eliminated, resulting in a simple structure and small footprint.

[0021] As one embodiment of the present invention, before step S101, the following steps are also included:

[0022] S10, Depress the rear spoiler of the car;

[0023] The car rear spoiler is placed on the workpiece pallet, and the transport mechanism transports the workpiece pallet to below the pressure head. The pressure drive unit drives the pressure head to move downward and press it onto the upper surface of the car rear spoiler.

[0024] S20. Attach the second label to the lower surface of the car's rear spoiler.

[0025] The bidding mechanism makes a second label and places the second label with the adhesive side down on the bidding platform. The telescopic drive unit drives the label-taking head to move downward and pick up the second label on the bidding platform. The moving drive unit drives the slider to move the rotating drive unit, the telescopic drive unit, and the label-taking head toward the bottom of the car rear spoiler. When the designated position is reached, the rotating drive unit drives the telescopic drive unit and the label-taking head to face upward. The telescopic drive unit drives the label-taking head to move upward and stick the adhesive side of the second label to the lower surface of the car rear spoiler.

[0026] S30, Reset the standard head;

[0027] The telescopic drive unit drives the label-taking head to move downwards, the rotary drive unit drives the telescopic drive unit and the label-taking head to face downwards, the moving drive unit drives the slider to reset the rotary drive unit, the telescopic drive unit and the label-taking head, and the transport mechanism transports the workpiece pallet to the next station.

[0028] Thus, a special workpiece tray for automotive rear spoilers is designed. The workpiece tray limits the left and right sides of the automotive rear spoiler to prevent scratches. The label located on the labeling platform can be passed through the first through hole from the bottom of the workpiece tray and affixed to the lower surface of the automotive rear spoiler. The downward pressure head fixes the upper surface of the labeling position on the automotive rear spoiler, ensuring that the automotive rear spoiler cannot move during the labeling process. This allows for labeling from below the automotive rear spoiler to the bottom surface without flipping the automotive rear spoiler, improving production efficiency and facilitating subsequent processes.

[0029] As one embodiment of the present invention, after step S105, the following step is further included:

[0030] The car spoiler is placed on the felt adhesive / unattachment fixture. The second clamping cylinder moves to clamp the car spoiler. The second robotic arm grabs the felt and peels off the release paper. A felt is placed on each side of the bottom of the car spoiler. The two felts are then attached to the bottom of the car spoiler. The second clamping cylinder moves to release the car spoiler and transport it to the next work station.

[0031] In this way, by placing the car spoiler on the felt application fixture, pressing the spoiler firmly, gripping the felt, and peeling off the release paper, it is easy to attach the two felts to the bottom of the spoiler, thus achieving automatic felt application, improving production efficiency, and with a simple structure.

[0032] As one embodiment of the present invention, in step S103, after the release paper of the first label strip is torn off, the release paper tearing mechanism releases the release paper of the first label strip, and the release paper vacuum blowing mechanism is set on one side of the release paper tearing mechanism. The release paper vacuum blowing mechanism blows the release paper of the first label strip into the first recycling bag.

[0033] In step S104, after the backing paper of the first label is torn off, the first robotic arm moves above the second recycling bag, the label tearing cylinder moves, and the backing paper of the first label falls into the second recycling bag.

[0034] In this way, the release paper of the first label can be easily recycled into the first recycling bag through the release paper vacuum blowing mechanism, and the backing paper of the first label can be easily recycled through the second recycling bag.

[0035] As one embodiment of the present invention, in step S105, the first robotic arm drives the mounting plate to move, and the camera is directed toward the left side of the upper surface of the car rear spoiler. The first light tube and the second light tube are turned on, and the camera takes a picture of the left side of the upper surface of the car rear spoiler to detect whether the left side of the first label strip on the upper surface of the car rear spoiler is properly pasted.

[0036] The first robotic arm moves the mounting plate, pointing the camera toward the right side of the upper surface of the car's rear spoiler. The camera takes a picture of the right side of the upper surface of the car's rear spoiler to check whether the right side of the first label strip on the upper surface of the car's rear spoiler is properly affixed. If both the left and right sides of the first label strip are properly affixed, the first and second light tubes are turned off.

[0037] Thus, since the car's rear spoiler has an arc-shaped structure, the first robotic arm drives the mounting plate to move to the left to inspect the left side of the first label strip on the upper surface of the car's rear spoiler. The first robotic arm also drives the mounting plate to move to the right to inspect the right side of the first label strip on the upper surface of the car's rear spoiler. This avoids the problem of unclear images of the left and right sides of the upper surface of the car's rear spoiler when the camera is shooting the car's rear spoiler from the front.

[0038] To achieve the above objectives, in a second aspect, the present invention also provides an automatic labeling device for automobile rear spoilers, used to perform the automatic labeling method for automobile rear spoilers as described in any of the above claims, including a first frame, a first robotic arm, a mounting plate, a label pasting fixture, a release paper tearing mechanism, and a three-axis gripping mechanism;

[0039] The first robotic arm is disposed on one side of the first frame, and the mounting plate is disposed on the first robotic arm. The mounting plate is provided with a workpiece suction cup assembly, a label suction cup assembly, a pressure-removing cylinder, a label tearing cylinder, and a camera. The first robotic arm uses the workpiece suction cup assembly to pick up a car rear spoiler and place it on the label pasting fixture. The label pasting fixture presses the car rear spoiler with a first pressing cylinder. The workpiece suction cup assembly is disposed at one end of the mounting plate, and the label suction cup assembly, pressure-removing cylinder, and label tearing cylinder are disposed at the other end of the mounting plate. The label suction cup assembly includes two or more suction cups, and the mounting plate is provided with two or more pressure-removing cylinders, which are arranged alternately.

[0040] The first frame is provided with a first label strip placement area. The label pasting fixture and the release paper tearing mechanism are arranged on the first frame. The release paper tearing mechanism is arranged between the first label strip placement area and the label pasting fixture. The first robot arm is used to pick up the first label strip through the label suction cup assembly. The release paper tearing mechanism is used to clamp the release paper of the first label strip. The first robot arm is used to drive the label suction cup assembly to move and tear off the release paper of the first label strip. The first robot arm pastes the first label strip to the upper surface of the car rear spoiler. The first robot arm presses the first label strip firmly through the pressing cylinder. The first robot arm tears off the back paper of the first label strip through the label tearing cylinder.

[0041] The camera detects whether the first label is properly affixed. The three-axis gripping mechanism is located on one side of the first frame and is used to transport the car rear spoiler to the next workstation.

[0042] Unlike existing technologies, the technical solution of this application uses a first robotic arm and a workpiece suction cup assembly to pick up a car rear spoiler. The car rear spoiler has a long, curved arc structure. The workpiece suction cup assembly is adapted to the car rear spoiler. The car rear spoiler is placed on a label pasting fixture, which is also adapted to the structure of the car rear spoiler. A first clamping cylinder fixes the car rear spoiler. The first clamping cylinder contacts the upper surface of the car rear spoiler with a flexible material to avoid scratching the upper surface of the car rear spoiler. The label suction cup assembly, the pressure-removing cylinder, and the label tearing cylinder are located at the other end of the mounting plate. The suction cup assembly picks up the long strip of the first label, the release paper is torn off by the release paper tearing mechanism, the first label is pressed firmly by the pressure cylinder, and the backing paper of the first label is torn off by the label tearing cylinder. This allows for labeling of the upper surface of a car rear spoiler. The release paper tearing mechanism removes the release paper of the first label in one go, eliminating the need to wait for the unwinding and rewinding of the feed roll, thus improving production efficiency. A single robotic arm moves the workpiece suction cup assembly, label suction cup assembly, pressure cylinder, and label tearing cylinder, eliminating the need for multiple motion mechanisms, resulting in a simple structure and small footprint.

[0043] As one embodiment of the present invention, the automatic labeling equipment for automobile rear spoiler includes a second frame, a label dispensing mechanism, a label picking mechanism, a workpiece tray, and a pressing mechanism. The label dispensing mechanism is disposed on the second frame and is provided with a label dispensing platform.

[0044] The label-taking mechanism includes a mounting base, a slider, a moving drive unit, a rotating drive unit, a telescopic drive unit, and a label-taking head. The mounting base is mounted on the second frame and has a slide rail that moves horizontally. The slider is slidably mounted on the slide rail. The label-taking head is mounted on the telescopic drive unit, which is mounted on the rotating drive unit. The rotating drive unit is mounted on the slider. The moving drive unit drives the slider to move relative to the slide rail along its extension direction. The rotating drive unit drives the telescopic drive unit and the label-taking head to rotate.

[0045] The workpiece tray is mounted on the frame via a transport mechanism. The workpiece tray is vertically higher than the label-taking head. The workpiece tray is used to place a car rear spoiler. The workpiece tray includes a first limiting block, a second limiting block, and a first through hole. The cross-sectional shape of the first limiting block matches the shape of the left side of the car rear spoiler, and the cross-sectional shape of the second limiting block matches the shape of the right side of the car rear spoiler. The first through hole is located below the first limiting block.

[0046] The pressing mechanism includes a pressing head, which is positioned opposite the first through hole. The pressing head is vertically higher than the car rear spoiler on the workpiece tray. The transport mechanism transports the workpiece tray to a position below the pressing head. The pressing head is used to press down on the upper surface of the car rear spoiler on the workpiece tray. The label-taking head is used to pass through the first through hole and attach a second label to the lower surface of the car rear spoiler.

[0047] Thus, a special workpiece tray for automotive rear spoilers is designed. The workpiece tray limits the left and right sides of the automotive rear spoiler to prevent scratches. The label located on the labeling platform can be passed through the first through hole from the bottom of the workpiece tray and affixed to the lower surface of the automotive rear spoiler. The downward pressure head fixes the upper surface of the labeling position on the automotive rear spoiler, ensuring that the automotive rear spoiler cannot move during the labeling process. This allows for labeling from below the automotive rear spoiler to the bottom surface without flipping the automotive rear spoiler, improving production efficiency and facilitating subsequent processes.

[0048] In one embodiment of the present invention, the automatic labeling equipment for automobile rear spoilers further includes a felt adhesive removal fixture and a second robotic arm. The second robotic arm is positioned relative to the three-axis gripping mechanism, and the felt adhesive removal fixture is positioned on one side of the three-axis gripping mechanism. The second robotic arm places the automobile rear spoiler on the felt adhesive removal fixture, which presses the automobile rear spoiler with a second pressing cylinder. The second robotic arm grips the felt and peels off the release paper from the felt. The second robotic arm then attaches two felts to the bottom of the automobile rear spoiler. The second pressing cylinder releases the automobile rear spoiler. The second robotic arm is used to transport the automobile rear spoiler to the next workstation.

[0049] Thus, the structure and principle of the release paper for tearing the felt are similar to those of the release paper tearing mechanism described above. By placing the car rear spoiler on the felt adhesive tool, pressing the car rear spoiler, gripping the felt, and tearing off the release paper of the felt, it is convenient to stick the two felts to the bottom of the car rear spoiler respectively, realizing automatic felt application, improving production efficiency, and with a simple structure.

[0050] As one embodiment of the present invention, the automatic labeling equipment for automobile rear spoiler further includes a release paper vacuum blowing mechanism, a first recycling bag and a second recycling bag. The release paper vacuum blowing mechanism is disposed on one side of the release paper tearing mechanism. The first recycling bag is disposed between the first label strip placement location and the label pasting fixture. The first recycling bag is disposed below the release paper vacuum blowing mechanism. The release paper vacuum blowing mechanism is used to blow the release paper of the first label strip into the first recycling bag.

[0051] The second recycling bag is located behind the label pasting fixture, and the first robotic arm is used to recycle the backing paper of the first label strip into the second recycling bag.

[0052] In this way, the release paper of the first label can be easily recycled into the first recycling bag through the release paper vacuum blowing mechanism, and the backing paper of the first label can be easily recycled through the second recycling bag.

[0053] In one embodiment of the present invention, a rotation unit and a tilting unit are provided on the back of the mounting plate. The rotation unit is used to drive the mounting plate to rotate, and the tilting unit is used to drive the mounting plate to tilt.

[0054] The mounting plate is also provided with a first lamp tube and a second lamp tube, which extend along a first direction and are parallel to each other. The camera is disposed between the first lamp tube and the second lamp tube.

[0055] In this way, the mounting plate can be easily rotated and tilted by the rotary unit and tilting unit, changing the position of the workpiece suction cup assembly, label suction cup assembly, pressure cylinder, and label tearing cylinder, and adjusting the angle of the camera, the first lamp tube, and the second lamp tube, so as to facilitate shooting the left and right sides of the upper surface of the car rear spoiler, so that the camera is directly facing the left and right sides of the upper surface of the car rear spoiler, thereby improving the shooting and recognition accuracy.

[0056] The above description of the invention is merely an overview of the technical solution of this application. In order to enable those skilled in the art to better understand the technical solution of this application and to implement it based on the description and drawings, and to make the above-mentioned objectives and other objectives, features and advantages of this application easier to understand, the following description is provided in conjunction with the specific embodiments and drawings of this application.

[0101] Existing labeling machines are unable to label car rear spoilers, resulting in low production efficiency and complex structures.

[0102] Therefore, this application provides an automatic labeling method and equipment for a car rear spoiler. The method involves using a workpiece suction cup assembly 31 to pick up a car rear spoiler 18, a label pasting fixture 4 to fix the car rear spoiler 18, a label suction cup assembly 32 to pick up a first label strip 8, a release paper tearing mechanism 5 to tear the release paper of the first label strip 8, a pressing cylinder 33 to press the first label strip 8 firmly, and a label tearing cylinder 34 to tear off the backing paper of the first label strip 8. This allows for labeling of the upper surface 181 of the car rear spoiler 18. The label pasting fixture 4 can... The system secures the rear spoiler 18 of the car to prevent scratches. The label suction cup assembly 32 picks up the first label strip 8, allowing for one-time pickup of the long label strip 8. The release paper tearing mechanism 5 tears off the release paper of the first label strip 8 in one go, eliminating the need to wait for the feed roll to unwind and rewind, thus improving production efficiency. The workpiece suction cup assembly 31 is positioned at one end of the mounting plate 3, while the label suction cup assembly 32, the pressure cylinder 33, and the label tearing cylinder 34 are positioned at the other end of the mounting plate 3. This eliminates the need for multiple motion mechanisms, resulting in a simple structure and a small footprint.

[0103] According to some embodiments of this application, please refer to Figures 1 to 13 This embodiment relates to an automatic labeling method for automobile rear spoilers, including the following steps:

[0104] S101, Absorbs the rear spoiler 18 of the car;

[0105] The workpiece tray 7 moves the car rear spoiler 18 to the designated position. The first robot arm 2 moves the mounting plate 3 above the workpiece tray 7. At this time, the workpiece suction cup assembly 31 is located at the bottom of the mounting plate 3 in the vertical direction (in the direction indicated by arrow z in the figure). The workpiece suction cup assembly 31 picks up the car rear spoiler 18.

[0106] S102, Fixed car rear spoiler 18;

[0107] The first robotic arm 2 places the car rear spoiler 18 on the label pasting fixture 4, and the first clamping cylinder 41 moves to clamp the car rear spoiler 18.

[0108] S103, Extract the first label 8;

[0109] The first robotic arm 2 moves the mounting plate 3 to above the first label strip placement location 82. The first robotic arm 2 rotates the mounting plate 3 counterclockwise, so that the label suction cup assembly 32, the pressure cylinder 33, and the label tearing cylinder 34 are located at the bottom of the mounting plate 3 in the vertical direction (in the direction indicated by arrow z in the figure), and the workpiece suction cup assembly 31 is located at the top of the mounting plate 3 in the vertical direction (in the direction indicated by arrow z in the figure). The label suction cup assembly 32 picks up the first label strip 8, and the first robotic arm 2 moves the first label strip 8 to the release paper tearing mechanism 5. The release paper tearing mechanism 5 clamps the release paper of the first label strip 8, and the first robotic arm 2 moves to tear off the release paper of the first label strip 8.

[0110] S104. Attach the first label strip 8 to the rear spoiler 18 of the car.

[0111] The first robotic arm 2 moves to stick the first label strip 8 to the upper surface 181 of the car rear spoiler 18. The pressing cylinder 33 and the label tearing cylinder 34 are located on the same side of the label suction cup assembly 32 on the mounting plate 3. The pressing cylinder 33 moves downward to press the first label strip 8 firmly, and the label tearing cylinder 34 moves to clamp and tear off the back paper of the first label strip 8.

[0112] S105. Check whether the first label strip 8 is properly affixed;

[0113] Camera 37 detects whether the first label strip 8 is properly affixed. If the first label strip 8 is properly affixed, the first clamping cylinder 41 moves to release the car rear spoiler 18. The first robotic arm 2 rotates the mounting plate 3 clockwise so that the workpiece suction cup assembly 31 is located at the bottom of the mounting plate 3 in the vertical direction (in the direction indicated by arrow z in the figure). The three-axis gripping mechanism 6 transports the car rear spoiler 18 to the next work station.

[0114] In this embodiment, as Figure 11 As shown, the car rear spoiler 18 is a long, curved structure, and the first label strip 8 is a long, narrow structure. All the equipment is designed according to the shape and structure of the car rear spoiler 18 and the first label strip 8.

[0115] like Figure 4 As shown, the workpiece suction cup assembly 31 is located at the bottom of the mounting plate 3. The workpiece suction cup assembly 31 is used to pick up the car rear spoiler 18. The workpiece suction cup assembly 31 is equipped with four telescopic suction cups, which are arranged in an arc shape corresponding to the shape of the car rear spoiler 18. The label suction cup assembly 32 is equipped with four label suction cups, which are arranged in an arc shape according to the upper surface of the car rear spoiler 18 to avoid scratching the upper surface 181 of the car rear spoiler 18.

[0116] like Figure 5As shown, the label pasting fixture 4 is used to place the car rear spoiler 18. The label pasting fixture 4 includes four sets of support rods 42. Each set of support rods 42 includes two support rods 42. The four sets of support rods 42 extend along the length of the label pasting fixture 4. The height of the four sets of support rods 42 is matched with that of the car rear spoiler 18, with a structure that is high in the middle and low at both ends.

[0117] like Figure 3 and Figure 6 As shown, the first label strip placement 82 is set in front of the label pasting fixture 4. There are two first label strip placements 82, and multiple first label strips 8 are stacked on the two first label strip placements 82 respectively. The release paper on the left side of the first label strip 8 extends beyond the pasting surface of the first label strip 8, which is convenient for the clamping cylinder of the release paper tearing mechanism 5 to clamp it. The first robot arm 2 drives the first label strip 8 to move and tear off the release paper of the first label strip 8. The first robot arm 2 then pastes the first label strip 8 onto the upper surface 181 of the car rear spoiler 18.

[0118] like Figure 4 , Figure 6 As shown, in Figure 6 The label suction cup assembly 32, the pressure-removing cylinder 33, and the label tearing cylinder 34 are located at the bottom of the mounting plate 3. The mounting plate 3 is provided with five pressure-removing cylinders 33, which are staggered from the four label suction cups. The four label suction cups adsorb the first label strip 8. The five pressure-removing cylinders 33 are arranged in an arc shape according to the shape of the car rear spoiler 18. When the pressure-removing cylinders 33 move downward, they can press the first label strip 8 firmly. In addition to the pressing function, when the camera detects that the first label strip 8 is not properly pasted, the pressure-removing cylinders 33 can peel the first label strip 8 off from the upper surface 181 of the car rear spoiler 18, which is also within the protection scope of this embodiment.

[0119] The mounting plate 3 is equipped with two label tearing cylinders 34, which are located on both sides of the five pressing cylinders 33. The two label tearing cylinders 34 can tear off the back paper of the first label strip 8.

[0120] Camera 37 is mounted on mounting plate 3. Camera 37 detects whether the first label strip 8 is properly pasted. The recognition function of camera 37 is a conventional technical means, which will not be described in detail here.

[0121] In this embodiment, the workpiece suction cup assembly 31, the label suction cup assembly 32, the five pressure-lifting cylinders 33, the two label tearing cylinders 34, and the camera 37 are all mounted on the mounting plate 3 and are controlled by the first robotic arm 2, eliminating the need to design multiple motion mechanisms.

[0122] In this embodiment, the car rear spoiler 18 is picked up by the workpiece suction cup assembly 31, the label pasting fixture 4 fixes the car rear spoiler 18, the first label strip 8 is picked up by the label suction cup assembly 32, the release paper of the first label strip 8 is torn off by the release paper tearing mechanism 5, the pressure-lifting cylinder 33 presses the first label strip 8 firmly, and the label tearing cylinder 34 tears off the back paper of the first label strip 8. This allows for the application of a label strip to the upper surface 181 of the car rear spoiler 18. The label pasting fixture 4 can fix the car rear spoiler 18, avoiding... The system prevents scratches on the car rear spoiler 18; the label suction cup assembly 32 picks up the first label strip 8, allowing for one-time pickup of the long first label strip 8; the release paper tearing mechanism 5 tears off the release paper of the first label strip 8 in one go, eliminating the need to wait for the unwinding and rewinding of the feed roll, thus improving production efficiency; the workpiece suction cup assembly 31 is set at one end of the mounting plate 3, while the label suction cup assembly 32, the pressure-lifting cylinder 33, and the label tearing cylinder 34 are set at the other end of the mounting plate 3, eliminating the need for multiple motion mechanisms, resulting in a simple structure and small footprint.

[0123] According to some embodiments of this application, optionally, the following steps are included before step S101:

[0124] like Figures 8 to 10 As shown;

[0125] S10, Downward-pressing rear spoiler 18;

[0126] The car rear spoiler 18 is placed on the workpiece tray 7. The transport mechanism transports the workpiece tray 7 to below the lower pressure head 121. The pressure drive unit drives the lower pressure head 121 to move downward and press it onto the upper surface 181 of the car rear spoiler 18.

[0127] S20. Affix the second label to the lower surface 182 of the car rear spoiler 18;

[0128] The dispensing mechanism 10 makes a second label and places the second label with the adhesive side down on the dispensing platform. The telescopic drive unit 115 drives the label-taking head 116 to move downward. The label-taking head 116 picks up the second label on the dispensing platform. The moving drive unit 113 drives the slider 112 to move the rotating drive unit 114, the telescopic drive unit 115, and the label-taking head 116 toward the bottom of the car rear spoiler 18. When the designated position is reached, the rotating drive unit 114 drives the telescopic drive unit 115 and the label-taking head 116 to move upward. The telescopic drive unit 115 drives the label-taking head 116 to move upward, and the adhesive side of the second label is attached to the lower surface 182 of the car rear spoiler 18.

[0129] S30, Reset the standard head 116;

[0130] The telescopic drive unit 115 drives the label-taking head 116 to move downwards, the rotation drive unit 114 drives the telescopic drive unit 115 and the label-taking head 116 to face downwards, the movement drive unit 113 drives the slider 112 to drive the rotation drive unit 114, the telescopic drive unit 115, and the label-taking head 116 to reset, and the transport mechanism transports the workpiece pallet 7 to the next station.

[0131] like Figure 8 As shown, the second label is the smaller QR code label. The second label is fed by the feeding roll. The label picking head 116 can pick up the QR code label, rotate it 180 degrees, and stick it from the bottom of the car rear spoiler 18 onto the lower surface of the car rear spoiler 18.

[0132] Thus, a dedicated workpiece tray 7 for the car rear spoiler 18 is designed. The workpiece tray 7 limits the left and right sides of the car rear spoiler 18 to prevent scratches. The label located on the labeling platform can be passed through the first through hole 73 from the bottom of the workpiece tray 7 and affixed to the lower surface 182 of the car rear spoiler 18. The pressing head 121 fixes the upper surface 181 of the labeling position on the car rear spoiler 18, ensuring that the car rear spoiler 18 cannot move during the labeling process. This allows the label to be applied to the bottom surface of the car rear spoiler 18 from below without flipping the car rear spoiler 18, improving production efficiency and facilitating subsequent processes.

[0133] According to some embodiments of this application, optionally, after step S105, the following step is also included:

[0134] The car rear spoiler 18 is placed on the felt adhesive removal fixture 13. The second pressing cylinder 131 moves to press the car rear spoiler 18. The second robotic arm 14 grabs the felt and peels off the release paper of the felt. A felt is placed on each side of the bottom of the car rear spoiler 18. The two felts are then glued to the bottom of the car rear spoiler 18. The second pressing cylinder 131 moves to release the car rear spoiler 18 and transport the car rear spoiler 18 to the next work station.

[0135] like Figure 12 and Figure 13 As shown, the structure and principle of the felt adhesive sticking tool 13 are similar to those of the label sticking tool 4. The felt adhesive sticking tool 13 includes four sets of support rods. Each set of support rods includes two support rods. The four sets of support rods extend along the length of the felt adhesive sticking tool 13. The height of the four sets of support rods is matched with that of the car rear spoiler 18, with a structure that is high in the middle and low at both ends.

[0136] The felt adhesive removal fixture 13 has two through holes. The second robot arm 14 grabs the felt and tears off the release paper of the felt. The principle of tearing off the release paper is the same as that of the release paper tearing mechanism 5, and will not be repeated here. The second robot arm 14 places the felt on the felt adhesive suction cup 151 of the two felt pushing cylinders 15. The two felt pushing cylinders 15 attach the felt to the lower surface of the car rear spoiler 18 through the two through holes of the felt adhesive removal fixture 13.

[0137] In this way, by placing the car rear spoiler 18 on the felt adhesive tool 13, pressing the car rear spoiler 18, grasping the felt, and tearing off the release paper of the felt, it is convenient to stick the two felts to the bottom of the car rear spoiler 18 respectively, realizing automatic felt application, improving production efficiency, and with a simple structure.

[0138] According to some embodiments of this application, optionally, such as Figure 6 As shown, in step S103, after the release paper of the first label strip 8 is torn off, the release paper tearing mechanism 5 releases the release paper of the first label strip 8. The release paper vacuum blowing mechanism 16 is set on one side of the release paper tearing mechanism 5. The release paper vacuum blowing mechanism 16 blows the release paper of the first label strip 8 into the first recycling bag 17.

[0139] In step S104, after the backing paper of the first label strip 8 is torn off, the first robotic arm 2 moves above the second recycling bag, the label tearing cylinder 34 moves, and the backing paper of the first label strip 8 falls into the second recycling bag.

[0140] Thus, the release paper of the first label strip 8 can be easily recycled into the first recycling bag 17 through the release paper vacuum blowing mechanism 16, and the back paper of the first label strip 8 can be easily recycled through the second recycling bag.

[0141] According to some embodiments of this application, optionally, in step S105, the first robotic arm 2 drives the mounting plate 3 to move, and the camera 37 is directed toward the left side of the upper surface 181 of the car rear spoiler 18. The first light tube 35 and the second light tube 36 are turned on, and the camera 37 takes a picture of the left side of the upper surface 181 of the car rear spoiler 18 to detect whether the left side of the first label strip 8 on the upper surface 181 of the car rear spoiler 18 is properly pasted.

[0142] The first robotic arm 2 moves the mounting plate 3 and directs the camera 37 toward the right side of the upper surface 181 of the car rear spoiler 18. The camera 37 takes a picture of the right side of the upper surface 181 of the car rear spoiler 18 and checks whether the right side of the first label strip 8 on the upper surface 181 of the car rear spoiler 18 is properly affixed. If both sides of the first label strip 8 are properly affixed, the first light tube 35 and the second light tube 36 are turned off.

[0143] Thus, since the rear spoiler 18 has an arc-shaped structure, the first robotic arm 2 drives the mounting plate 3 to move to the left to inspect the left side of the first label strip 8 on the upper surface 181 of the rear spoiler 18, and the first robotic arm 2 drives the mounting plate 3 to move to the right to inspect the right side of the first label strip 8 on the upper surface 181 of the rear spoiler 18. This avoids the problem of unclear images of the left and right sides of the upper surface 181 of the rear spoiler 18 when the camera 37 takes a frontal shot of the rear spoiler 18.

[0144] This embodiment also relates to an automatic labeling device for automobile rear spoilers, used to perform any of the above-mentioned automatic labeling methods for automobile rear spoilers, including a first frame 1, a first robotic arm 2, a mounting plate 3, a label pasting fixture 4, a release paper tearing mechanism 5, and a three-axis gripping mechanism 6.

[0145] The first robotic arm 2 is located on one side of the first frame 1, and the mounting plate 3 is located on the first robotic arm 2. The mounting plate 3 is equipped with a workpiece suction cup assembly 31, a label suction cup assembly 32, a pressing and peeling cylinder 33, a label tearing cylinder 34, and a camera 37. The first robotic arm 2 uses the workpiece suction cup assembly 31 to pick up the car rear spoiler 18 and place it on the label pasting fixture 4. The label pasting fixture 4 presses the car rear spoiler 18 with the first pressing cylinder 41. The workpiece suction cup assembly 31 is located at one end of the mounting plate 3, and the label suction cup assembly 32, the pressing and peeling cylinder 33, and the label tearing cylinder 34 are located at the other end of the mounting plate 3. The label suction cup assembly 32 includes two or more suction cups, and the mounting plate 3 is equipped with two or more pressing and peeling cylinders 33. The two or more suction cups and the two or more pressing and peeling cylinders 33 are arranged alternately.

[0146] The first frame 1 is provided with a first label strip placement area 82. The label pasting fixture 4 and the release paper tearing mechanism 5 are set on the first frame 1. The release paper tearing mechanism 5 is set between the first label strip placement area 82 and the label pasting fixture 4. The first robot arm 2 is used to pick up the first label strip 8 through the label suction cup assembly 32. The release paper tearing mechanism 5 is used to clamp the release paper of the first label strip 8. The first robot arm 2 is used to drive the label suction cup assembly 32 to move and tear off the release paper of the first label strip 8. The first robot arm 2 pastes the first label strip 8 to the upper surface 181 of the car rear spoiler 18. The first robot arm 2 presses the first label strip 8 firmly through the pressing cylinder 33. The first robot arm 2 tears off the back paper of the first label strip 8 through the label tearing cylinder 34.

[0147] Camera 37 detects whether the first label strip 8 is properly affixed. The three-axis gripping mechanism 6 is located on one side of the first frame 1. The three-axis gripping mechanism 6 is used to transport the car rear spoiler 18 to the next work station.

[0148] In this embodiment, as Figure 3As shown, the first frame 1 is provided with two first label strip placement positions 82, which are arranged in an arrangement. A label strip detection sensor 81 is provided at the first label strip placement position 82. The label strip detection sensor 81 is used to detect whether there is a first label strip 8 at the first label strip placement position 82. The label pasting fixture 4 and the release paper tearing mechanism 5 are installed on the first frame 1.

[0149] The structure and principle of the first robotic arm 2 are based on conventional technical means;

[0150] like Figure 4 As shown, mounting plate 3 is mounted on first robotic arm 2. First robotic arm 2 can rotate, tilt, and move mounting plate 3. Workpiece suction cup assembly 31, label suction cup assembly 32, five pressure-removing cylinders 33, two label tearing cylinders 34, and camera 37 are all mounted on mounting plate 3. Workpiece suction cup assembly 31 is located at one end of mounting plate 3, and label suction cup assembly 32, pressure-removing cylinders 33, and label tearing cylinders 34 are located at the other end of mounting plate 3. When first robotic arm 2 picks up car rear spoiler 18 through workpiece suction cup assembly 31, as... Figure 4 As shown, at this time, the workpiece suction cup assembly 31 is located at the lower end of the mounting plate 3; the first robot arm 2 adsorbs the first label strip 8 through the label suction cup assembly 32, as shown. Figure 6 As shown, during the process of the pressure-removing cylinder 33 pressing the first label strip 8 and the label tearing cylinder 34 tearing the back paper of the first label strip 8, the label suction cup assembly 32, the pressure-removing cylinder 33, and the label tearing cylinder 34 are located at the lower end of the mounting plate 3.

[0151] like Figure 5 As shown, the label pasting fixture 4 includes six first pressing cylinders 41, four sets of support rods 42, and a workpiece detection sensor 43. Each set of support rods 42 includes two support rods 42. The four sets of support rods 42 extend along the length of the label pasting fixture 4 to support the bottom of the car rear spoiler 18. The output end of the first pressing cylinder 41 is equipped with a pressure head. During use, the pressure head swings to the left or right to allow the car rear spoiler 18 to be placed. When the car rear spoiler 18 is placed on the four sets of support rods 42, the pressure head swings to the top of the car rear spoiler 18 and then moves down to press on the upper surface of the car rear spoiler 18 to fix the car rear spoiler 18. The workpiece detection sensor 43 is used to detect whether the car rear spoiler 18 is on the label pasting fixture 4 and then controls the six first pressing cylinders 41 to press the car rear spoiler 18.

[0152] like Figure 6As shown, the release paper tearing mechanism 5 is mainly a clamping cylinder. The clamping cylinder clamps one end of the release paper of the first label strip 8. As the label suction cup assembly 32 continuously adsorbs the first label strip 8, the first robotic arm 2 moves and can tear off the release paper of the first label strip 8. The clamping cylinder releases the release paper, and the release paper is blown into the first recycling bag 17 by the release paper vacuum blowing mechanism 16.

[0153] like Figure 7 As shown, the three-axis gripping mechanism 6 includes an X-axis moving module 61, a Y-axis moving module 62, a Z-axis moving module 63, and a workpiece suction cup assembly 31. The X-axis moving module 61 drives the workpiece suction cup assembly 31 to move along the X-axis direction, the Y-axis moving module 62 drives the workpiece suction cup assembly 31 to move along the Y-axis direction, and the Z-axis moving module 63 drives the workpiece suction cup assembly 31 to move along the Z-axis direction (in the direction indicated by arrow z in the figure). Through the movement of the X-axis moving module 61, the Y-axis moving module 62, and the Z-axis moving module 63, the car rear spoiler 18 located on the label pasting fixture 4 can be moved to the felt adhesive removal fixture 13.

[0154] The structure and principle of the X-axis moving module 61, Y-axis moving module 62, and Z-axis moving module 63 are conventional technical means and will not be described in detail here.

[0155] In this embodiment, a first robotic arm 2 and a workpiece suction cup assembly 31 pick up a car rear spoiler 18. The car rear spoiler 18 has a long, curved structure. The workpiece suction cup assembly 31 is adapted to the car rear spoiler 18. The car rear spoiler 18 is placed on a label pasting fixture 4, which is also adapted to the structure of the car rear spoiler 18. A first clamping cylinder 41 fixes the car rear spoiler 18. The first clamping cylinder 41 contacts the upper surface 181 of the car rear spoiler 18 with a flexible material to avoid scratching the upper surface 181 of the car rear spoiler 18. The label suction cup assembly 32, the pressure-removing cylinder 33, and the label tearing cylinder 34 are located at the other end of the mounting plate 3. The workpiece suction cup assembly 31 picks up the long strip of the first label 8, and the release paper mechanism 5 tears off the release paper of the first label 8. The pressure-lifting cylinder 33 presses the first label 8 firmly, and the label tearing cylinder 34 tears off the back paper of the first label 8. This allows for the application of labels to the upper surface 181 of the car rear spoiler 18. The release paper tearing mechanism 5 tears off the release paper of the first label 8 in one go, eliminating the need to wait for the unwinding and rewinding of the feed roll, thus improving production efficiency. The workpiece suction cup assembly 31, label suction cup assembly 32, pressure-lifting cylinder 33, and label tearing cylinder 34 are moved by a single robotic arm, eliminating the need for multiple motion mechanisms, resulting in a simple structure and small footprint.

[0156] According to some embodiments of this application, optionally, the automatic labeling equipment for automobile rear spoiler includes a second frame 9, a label dispensing mechanism 10, a label picking mechanism 11, a workpiece tray 7, and a pressing mechanism 12. The label dispensing mechanism 10 is disposed on the second frame 9 and is provided with a label dispensing platform.

[0157] The label-taking mechanism 11 includes a mounting base 111, a slider 112, a moving drive unit 113, a rotating drive unit 114, a telescopic drive unit 115, and a label-taking head 116. The mounting base 111 is mounted on the second frame 9. A slide rail 117 that moves horizontally is provided on the mounting base 111. The slider 112 is slidably mounted on the slide rail 117. The label-taking head 116 is mounted on the telescopic drive unit 115. The telescopic drive unit 115 is mounted on the rotating drive unit 114. The rotating drive unit 114 is mounted on the slider 112. The moving drive unit 113 is used to drive the slider 112 to move relative to each other along the extension direction of the slide rail 117. The rotating drive unit 114 is used to drive the telescopic drive unit 115 and the label-taking head 116 to rotate.

[0158] The workpiece tray 7 is set on the frame by a transport mechanism. The workpiece tray 7 is higher than the label picker head 116 in the vertical direction (in the direction indicated by arrow z in the figure). The workpiece tray 7 is used to place the car rear spoiler 18. The workpiece tray 7 includes a first limiting block 71, a second limiting block 72 and a first through hole 73. The cross-sectional shape of the first limiting block 71 matches the shape of the left side of the car rear spoiler 18, the cross-sectional shape of the second limiting block 72 matches the shape of the right side of the car rear spoiler 18, and the first through hole 73 is located below the first limiting block 71.

[0159] The pressing mechanism 12 includes a pressing head 121, which is positioned relative to the first through hole 73. The pressing head 121 is higher than the car rear spoiler 18 on the workpiece tray 7 in the vertical direction (in the direction indicated by arrow z in the figure). The transport mechanism transports the workpiece tray 7 to a position below the pressing head 121. The pressing head 121 is used to press down on the upper surface 181 of the car rear spoiler 18 on the workpiece tray 7. The label-taking head 116 is used to pass through the first through hole 73 to attach a second label to the lower surface 182 of the car rear spoiler 18.

[0160] The bidding mechanism 10 is a conventional material feeding and coiling mechanism; the specific bidding principle will not be described in detail.

[0161] The label-taking mechanism 11 drives the slider 112 to move relative to each other along the extension direction of the slide rail 117 via the moving drive unit 113, which in turn drives the rotary drive unit 114, the telescopic drive unit 115, and the label-taking head 116 to move relative to each other. The rotary drive unit 114 changes the direction of the telescopic drive unit 115 and the label-taking head 116, and the telescopic drive unit 115 drives the label-taking head 116 to take and apply labels.

[0162] In this embodiment, as Figure 10 As shown, the workpiece tray 7 includes a first limiting block 71, a second limiting block 72, a first support base 75, a second support base 76, a first through hole 73, and a second through hole 74. The first limiting block 71, the first support base 75, the second support base 76, and the second limiting block 72 are arranged sequentially from left to right.

[0163] The first limiting block 71 limits the left side of the car rear spoiler 18, and the left side of the car rear spoiler 18 is inserted into the limiting groove of the first limiting block 71. The second limiting block 72 limits the right side of the car rear spoiler 18, and the right side of the car rear spoiler 18 is inserted into the limiting groove of the second limiting block 72. The first limiting block 71 and the second limiting block 72 contact the left and right sides of the car rear spoiler 18 respectively to avoid scratching the upper and lower surfaces of the car rear spoiler 18.

[0164] The first through hole 73 is connected to the limiting groove of the first limiting block 71, and the second through hole 74 is connected to the limiting groove of the second limiting block 72. The first through hole 73 is located on the left side of the workpiece tray 7, and the second through hole 74 is located on the right side of the workpiece tray 7. A set of label dispensing mechanism 10, label picking mechanism 11 and pressing mechanism 12 are provided on each of the left and right sides of the workpiece tray 7, which can simultaneously label the left and right sides of the lower surface of the car rear spoiler 18.

[0165] like Figure 8 As shown, the pressing mechanism 12 presses down on the upper surface 181 of the car rear spoiler 18 located on the workpiece tray 7 through the pressing head 121. The pressing head 121 is made of flexible material to avoid scratching the upper surface 181 of the car rear spoiler 18.

[0166] Thus, a dedicated workpiece tray 7 for the car rear spoiler 18 is designed. The workpiece tray 7 limits the left and right sides of the car rear spoiler 18 to prevent scratches. The label located on the labeling platform can be passed through the first through hole 73 from the bottom of the workpiece tray 7 and affixed to the lower surface 182 of the car rear spoiler 18. The pressing head 121 fixes the upper surface 181 of the labeling position on the car rear spoiler 18, ensuring that the car rear spoiler 18 cannot move during the labeling process. This allows the label to be applied to the bottom surface of the car rear spoiler 18 from below without flipping the car rear spoiler 18, improving production efficiency and facilitating subsequent processes.

[0167] According to some embodiments of this application, optionally, the automatic labeling equipment for car rear spoilers also includes a felt adhesive removal fixture 13 and a second robotic arm 14. The second robotic arm 14 is positioned relative to the three-axis gripping mechanism 6, and the felt adhesive removal fixture 13 is positioned on one side of the three-axis gripping mechanism 6. The second robotic arm 14 places the car rear spoiler 18 on the felt adhesive removal fixture 13, and the felt adhesive removal fixture 13 presses the car rear spoiler 18 with a second pressing cylinder 131. The second robotic arm 14 grips the felt and peels off the release paper of the felt. The second robotic arm 14 then attaches two felts to the bottom of the car rear spoiler 18. The second pressing cylinder 131 releases the car rear spoiler 18, and the second robotic arm 14 is used to transport the car rear spoiler 18 to the next workstation.

[0168] like Figure 12 As shown, the structure and principle of the felt adhesive / removal fixture 13 are similar to those of the label pasting fixture 4. The felt adhesive / removal fixture 13 includes four sets of support rods, each set consisting of two support rods. The four sets of support rods extend along the length of the felt adhesive / removal fixture 13, and their height is matched to that of the car rear spoiler 18. The felt adhesive / removal fixture 13 is equipped with six second pressing cylinders 131, each with a pressing head at its output end. During use, the pressing head swings left or right to allow space for the car rear spoiler 18. After the car rear spoiler 18 is placed on the four sets of support rods, the pressing head swings to the top of the car rear spoiler 18 and then moves downwards to press against the upper surface of the car rear spoiler 18, thus fixing the car rear spoiler 18 in place. The felt detection sensor 132 is used to detect whether the car rear spoiler 18 is positioned above the felt adhesive / removal fixture 13.

[0169] like Figure 13 As shown, two felt pushing cylinders 15 are equipped with felt adhesive suction cups 151 for adsorbing felt. The second robot arm 14 places the felt on the felt adhesive suction cups 151 of the two felt pushing cylinders 15. The two felt pushing cylinders 15 push outward through the two through holes of the felt adhesive tooling 13 to attach the felt to the lower surface of the car rear spoiler 18.

[0170] Thus, the structure and principle of the release paper for tearing the felt are similar to those of the release paper tearing mechanism 5 mentioned above. By placing the car rear spoiler 18 on the felt adhesive tool 13, pressing the car rear spoiler 18, gripping the felt, and tearing off the release paper of the felt, it is convenient to stick the two felts to the bottom of the car rear spoiler 18 respectively, thereby realizing automatic felt application, improving production efficiency, and having a simple structure.

[0171] According to some embodiments of this application, optionally, the automatic labeling equipment for automobile rear spoiler also includes a release paper vacuum blowing mechanism 16, a first recycling bag 17 and a second recycling bag. The release paper vacuum blowing mechanism 16 is disposed on one side of the release paper tearing mechanism 5. The first recycling bag 17 is disposed between the first label strip placement location 82 and the label pasting fixture 4. The first recycling bag 17 is disposed below the release paper vacuum blowing mechanism 16. The release paper vacuum blowing mechanism 16 is used to blow the release paper of the first label strip 8 into the first recycling bag 17.

[0172] The second recycling bag is located behind the label pasting fixture 4, and the first robotic arm 2 is used to recycle the backing paper of the first label strip 8 into the second recycling bag.

[0173] like Figure 6 As shown, the release paper vacuum blowing mechanism 16 mainly consists of a blowing head. The blowing head faces the clamping cylinder of the release paper tearing mechanism 5. After the clamping cylinder releases the release paper, the blowing head blows the release paper into the first recycling bag 17 for recycling. The second recycling bag is located behind the label pasting fixture 4. After the first robotic arm 2 tears off the back paper of the first label strip 8 through the label tearing cylinder 34, it moves above the second recycling bag and releases the back paper of the first label strip 8 through the label tearing cylinder 34. The back paper of the first label strip 8 falls into the second recycling bag.

[0174] Thus, the release paper of the first label strip 8 can be easily recycled into the first recycling bag 17 through the release paper vacuum blowing mechanism 16, and the back paper of the first label strip 8 can be easily recycled through the second recycling bag.

[0175] According to some embodiments of this application, optionally, a rotation unit and a tilting unit are provided on the back of the mounting plate 3. The rotation unit is used to drive the mounting plate 3 to rotate, and the tilting unit is used to drive the mounting plate 3 to tilt.

[0176] The mounting plate 3 is also provided with a first lamp tube 35 and a second lamp tube 36. The first lamp tube 35 and the second lamp tube 36 extend along the first direction. The first lamp tube 35 and the second lamp tube 36 are parallel to each other. The camera 37 is located between the first lamp tube 35 and the second lamp tube 36.

[0177] like Figure 4 As shown, the first robotic arm 2 can rotate the mounting plate 3 through the rotary unit and tilt the mounting plate 3 through the tilting unit. During the recognition process of the camera 37, the first lamp tube 35 and the second lamp tube 36 are turned on. The camera 37 first faces the left side of the upper surface 181 of the car rear spoiler 18, and then faces the right side of the upper surface 181 of the car rear spoiler 18, thereby improving the recognition accuracy of the camera 37.

[0178] In this way, the mounting plate 3 can be rotated and tilted by the rotary unit and tilting unit, changing the position of the workpiece suction cup assembly 31, the label suction cup assembly 32, the pressure and peeling cylinder 33, and the label tearing cylinder 34, and adjusting the angle of the camera 37, the first lamp tube 35, and the second lamp tube 36, so as to facilitate shooting the left and right sides of the upper surface 181 of the car rear spoiler 18, so that the camera 37 is directly facing the left and right sides of the upper surface 181 of the car rear spoiler 18, thereby improving the shooting and recognition accuracy.

[0179] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection of the present invention. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of the present invention, or equivalent structural or procedural transformations made using the content of the present invention's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of patent protection of the present invention.
