[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present invention are shown in the accompanying drawings.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this invention can be combined with each other. The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] like Figure 1As shown, the present invention provides an automatic labeling and testing device for car keys, including a base 1, on which a label machine module 2 and a robotic arm 3 are installed; wherein, the label machine module 2 is used to separate the label attached to the material strip from the material strip; the robotic arm 3 is used to pick up the label separated by the label machine module 2 and attach the picked-up label to the car key.

[0034] A turntable 4 is also installed on the base 1. The turntable 4 is rotatably mounted on the base 1. Multiple fixed stations 5 are installed on the turntable 4. Each fixed station 5 has a receiving slot for accommodating car keys. After the car key is placed in the receiving slot, the position of the car key around its perimeter is restricted. At the same time, the multiple fixed stations 5 on the turntable 4 are evenly spaced along the circumference of the turntable 4. Since the labeling of the car key in this invention requires six steps: S1, placing the car key to be labeled in the fixed station 5; S2, checking the placement of the car key in the fixed station 5; S3, affixing the label to the car key located in the fixed station 5; S4, pressing the label affixed to the car key; S5, checking the positional accuracy of the label affixed to the car key; S6, unloading the car key after the check. When designing the fixed workstations 5 on the turntable 4, the number of fixed workstations 5 on the turntable 4 can correspond to the number of labeling steps for the car key, the number of fixed workstations 5 on the turntable 4 can be greater than the number of labeling steps for the car key, or the number of fixed workstations 5 on the turntable 4 can be less than the number of labeling steps for the car key.

[0035] In this invention, there are four fixed workstations 5 on the turntable 4. Based on the rotation direction of the turntable 4, the four fixed workstations 5 are arranged at intervals along the circumference of the turntable 4. Steps S1 and S2 are completed at one fixed workstation 5, step S3 is completed at one fixed workstation 5, step S4 is completed at one fixed workstation 5, and steps S5 and S6 are completed at one fixed workstation 5. Simultaneously, to ensure that each car key placed in a fixed workstation 5 can complete steps S1 to S5, a fixed plate 10 is also provided at the center of the turntable 4. The fixed plate 10 is fixedly supported on the base 1. When the turntable 4 rotates, the turntable 4 and the fixed plate 10 form a relative motion. To ensure the installation of the fixed plate 10, the turntable 4 also has a central hole, and the fixed plate 10 is installed in or above the central hole. In this invention, when the fixed plate 10 is arranged, its surface can be flush with the surface of the turntable 4, or it can be located above the turntable 4. Of course, in this invention, the fixed disk 10 can also be set as an annular shape and the turntable 4 can be located at the center of the fixed disk 10. In this case, the fixed disk 10 can be directly supported by the bracket.

[0036] In this invention, a label pressing module 7 is also installed on the turntable 4. When the robotic arm 3 picks up the label and affixes it to the car key located in the fixed station 5, the car key with the label affixed rotates synchronously with the turntable 4 to the underside of the label pressing module 7 through the rotation of the turntable 4. The label pressing module 7 presses the label onto the car key with the label affixed, so that the label is pressed and fixed on the car key, thereby realizing the labeling of the car key.

[0037] In this invention, a loading detection module 6 is installed on both the fixed plate 10 and the machine base 1. The loading detection module 6 is used to detect whether there is a car key in the fixed station 5 and whether the car key is placed flat in the fixed station 5. A labeling detection module 8 is also installed on the fixed plate 10. After the label is pressed and fixed on the car key by the rotation of the turntable 4, it can enter the detection area of ​​the labeling detection module 8 with the rotation of the turntable 4. The labeling detection module 8 detects the car key after labeling and detects whether the label pressed and fixed on the car key is misaligned. At the same time, a unloading module 9 is also installed on the machine base 1. After the detection module detects the car key after labeling, the car key can enter the unloading area of ​​the unloading module 9 with the rotation of the turntable 4. At this time, the unloading module 9 can take out the car key after labeling, pressing and fixing and detection in the fixed station 5 and transfer it to the material box 13.

[0038] In this invention, when the loading and inspection module 6 can be used to inspect the car key placed in the fixed station 5, the loading and inspection module 6 can be directly installed on the base 1 or the fixed plate 10. When the labeling and inspection module 8 can be used to inspect the car key after labeling, the labeling and inspection module 8 can be directly installed on the base 1 or simultaneously installed on the fixed plate 10 and the base 1. When the unloading of the car key after labeling, pressing, and inspection can be met, the unloading module 9 can be directly installed on the fixed plate 10.

[0039] Since the labels are attached to the conveyor belt before being picked up by the robotic arm 3, and the conveyor belt with the labels attached is wound to form a tray, the labels attached to the conveyor belt need to be peeled off before being picked up by the robotic arm 3. To achieve automatic peeling of the labels from the conveyor belt, such as... Figures 2 to 4 As shown, the label machine module 2 of the present invention includes a stand 200 mounted on a base 1. The stand 200 is equipped with a rotatable reel 201, a label separation module 203, and a take-up roller 205. The reel 201 is used to mount reels of material that have not been peeled off from the material strip. The label separation module 203 is used to peel off the labels from the material strip so that the robot arm 3 can pick up the labels. The take-up roller 205 is used to rewind the material strip after the labels have been peeled off.

[0040] To ensure that the strip drawn from the reel 201 can smoothly enter the label separation module 203, a guide roller assembly 202 is also installed on the stand 200. The guide roller assembly 202 is composed of multiple guide roller groups 202, and the guide roller assembly 202 is located between the reel 201 and the label separation module 203. In this invention, there are two guide rollers 2020 in the guide roller 2048 group. The two guide rollers 2020 are spaced apart by a certain distance, and the two guide rollers 2020 are installed at different heights on the stand 200. When the strip with the label attached is guided out by the two guide rollers 2020, its height is higher than the feeding height of the label separation module 203.

[0041] To ensure that the labels can be wound onto the take-up roller 205 after being peeled from the material strip, and to facilitate the traction of the material strip, a traction roller assembly 204 is also installed on the support frame 200. The traction roller assembly 204 is located between the label separation module 203 and the take-up roller 205. The traction roller assembly 204 not only tractions and conveys the material strip but also transports the traction strip to the take-up roller 205 for winding. Since the traction roller assembly 204 needs to traction the material strip, the number of traction rollers 2041 in the traction roller assembly 204 is at least two, with the two traction rollers 2041 working together to clamp and convey the material strip. In this invention, while ensuring that the traction rollers 2041 can clamp and convey the material strip, the two cooperating traction rollers 2041 can be installed at the same height or at different heights. In this invention, the label can be automatically wound onto the take-up roller 205 after being peeled off from the material strip. The upright 200 is also equipped with a drive motor 206, which is connected to the take-up roller 205 via belt drive.

[0042] To facilitate the traction and conveying of the material strip, and to allow workers to pass the strip with the label removed between the two cooperating traction rollers 2041, two mounting seats 2040 can be installed on the stand 200. One of the cooperating traction rollers 2041 is supported on the two mounting seats 2040 by bearings. The output end of the drive motor 206 is connected to one end of the traction roller 2041 via belt drive. At the same time, a straight groove 2042 extending horizontally to one side of the traction roller 2041 is opened on each of the two mounting seats 2040. A U-shaped frame 2043 is installed in both straight grooves 2042, with the two ends of the U-shaped frame 2043 respectively installed in the two straight grooves 2042. Among the two cooperating traction rollers 2041, the other traction roller 2041 is rotatably mounted on both ends of the U-shaped frame 2043 by bearings.

[0043] In order to drive the U-shaped frame 2043 to slide along the axial direction of the straight groove 2042, so that the traction roller 2041 on the U-shaped frame 2043 can abut against or move away from the traction roller 2041 it is paired with, a fixing plate 2044 is also connected between the two mounting seats 2040. The fixing plate 2044 is located on the side of the U-shaped frame 2043 away from the traction roller 2041, and multiple adjusting bolts 2045 are also passed through the fixing plate 2044. The tail of the adjusting bolt 2045 is fixed to the back fixing hole of the U-shaped frame 2043. When the adjusting bolt 2045 moves towards the U-shaped frame 2043 within the insertion hole, it pushes the U-shaped frame 2043 forward along the straight groove 2042. This causes the traction roller 2041 on the U-shaped frame 2043 to move closer to the other traction roller 2041 supported on the two mounting seats 2040, thereby clamping the material belt between the two mating traction rollers 2041. The drive motor 206 then drives the traction roller 2041 supported on the two mounting seats 2040, enabling the material belt to be pulled and conveyed simultaneously with clamping. In this invention, an adjusting structure is also installed between the two mounting seats 2040 to facilitate the pushing of the adjusting bolt 2045. This adjusting structure allows for the adjustment of the bolt 2045's forward and backward movement, enabling the traction roller 2041 supported on the two mounting seats 2040 and the traction roller 2041 supported on the U-shaped frame 2043 to quickly engage or disengage.

[0044] In this invention, the adjustment structure includes a rotatable flip plate 2047 mounted on two mounting bases 2040. The flip plate 2047 is located on the side of the fixed plate 2044 away from the U-shaped frame 2043, that is, the fixed plate 2044 is located between the U-shaped frame 2043 and the flip plate 2047. The adjustment structure also includes a telescopic spring 2046 sleeved on the adjusting bolt 2045. One end of the telescopic spring 2046 abuts against the head of the adjusting bolt 2045, and the other end of the telescopic spring 2046 abuts against the fixed plate 2044. Rollers 2048 are also installed on the side of the flip plate 2047 near the fixed plate 2044. The number of rollers 2048 is equal to the number of adjusting bolts 2045. The multiple rollers 2048 correspond one-to-one with the multiple adjusting bolts 2045, and the wheel surface of the rollers 2048 abuts against the head of the adjusting bolts 2045.

[0045] Furthermore, to make the flipping plate 2047 more stable during flipping, an arc-shaped groove 2049 can be formed on each of the two mounting seats 2040. The center of the arc-shaped groove 2049 is concentric with the rotation center of the flipping plate 2047, and the two sides of the flipping plate 2047 also have end shafts respectively inserted into the two arc-shaped grooves 2049. Furthermore, to facilitate the installation of the flipping plate 2047, a rotating shaft can be installed on both mounting seats 2040, and one side of the flipping plate 2047 can be fixed to the rotating shaft, thereby making the flipping of the flipping plate 2047 smoother. In this invention, to facilitate the operator's flipping of the flipping plate 2047, a handle can be installed on one end of the rotating shaft used to install the flipping plate 2047, and the handle is located on the outside of one of the mounting seats 2040, allowing the operator to rotate the rotating shaft by the handle, thereby flipping the flipping plate 2047.

[0046] When it is necessary to bring the two traction rollers 2041 in the traction roller assembly 204 located between the label separation module 203 and the receiving roller 205 into contact, rotate the tilting plate 2047 until it is horizontal. As the tilting plate 2047 rotates, the rollers 2048 on the tilting plate 2047 push the adjusting bolt 2045 towards the U-shaped frame 2043, compressing the telescopic spring 2046. Simultaneously, the adjusting bolt 2045 pushes the U-shaped frame 2043, causing the traction rollers 2041 on the U-shaped frame 2043 to move closer to the traction rollers 2041 supported on the two mounting seats 2040, ultimately bringing them into contact. When it is necessary to bring the traction rollers 2041 on the U-shaped frame 2043 and the traction rollers 2041 supported on the two mounting seats 2040 into contact... When moving away, rotate the flip plate 2047 upwards. As the flip plate 2047 rotates, the rollers 2048 on the flip plate 2047 gradually move away from the fixed plate 2044, causing the adjusting bolt 2045 to gradually lose the push of the rollers 2048. At this time, the telescopic spring 2046 pushes the adjusting bolt 2045 backwards through its own elasticity. As the adjusting bolt 2045 moves backwards, it drives the U-shaped frame 2043 to move backwards synchronously. This causes the guide roller 2020 on the U-shaped frame 2043 to lose its contact with another guide roller 2020 on the guide roller group 202. As a result, the traction roller 2041 on the U-shaped frame 2043 automatically moves away from the traction roller 2041 supported on the two mounting seats 2040, making it easier for the worker to pass the material belt between the traction roller 2041 on the U-shaped frame 2043 and the traction roller 2041 supported on the two mounting seats 2041.

[0047] In this invention, to enable automatic peeling of labels attached to the material strip, the label separation module 203 includes a horizontal platform 2030 and a feed roller 2037 mounted on the upright 200. The front end of the horizontal platform 2030 extends towards the turntable 4, and the feed roller 2037 is located at the end of the horizontal platform 2030 near the reel 201. The lead-out surface of the feed roller 2037 is lower than the upper surface of the horizontal platform 2030, so that the material strip unwound from the reel 201 can adhere to the horizontal platform 2030 and advance after being guided and fed out by the guide rollers 2048 and the feed roller 2037. Simultaneously... The lower surface of the water platform 2030, near the turntable 4, is also provided with an inclined surface 2031. The height of the inclined surface 2031 near the turntable 4 is higher than the height of the inclined surface 2031 near the reel 201. This allows the material strip to be guided downwards gradually after being drawn out and folded at the front end of the water platform 2030. When the material strip with the label attached moves forward along the water platform 2030, it folds downwards after being drawn out from the end of the water platform 2030 near the turntable 4. Because the label attached to the material strip has a certain degree of rigidity, when the material strip folds at the front end of the water platform 2030, the label attached to the material strip separates at the same time as the material strip folds. The separated label then moves forward under the guidance of the material strip, eventually separating the label from the material strip.

[0048] To ensure more precise positioning of the labels attached to the conveyor belt when they are separated at the front end of the water platform 2030, a cover plate 2038 is installed at the end of the water platform 2030 near the turntable 4. The cover plate 2038 is located on the upper surface of the water platform 2030, and the lower surface of the cover plate 2038 has a through groove adapted to the width of the conveyor belt. When the conveyor belt with the label attached passes between the cover plate 2038 and the water platform 2030, the two sides of the conveyor belt can be restricted by the two sides of the through groove, making the position of the conveyor belt more precise when it is guided forward on the water platform 2030. At the same time, a limiting groove 2039 corresponding to the label on the conveyor belt is also opened at the bottom of the through groove. The position of the limiting groove 2039 in the width direction of the through groove corresponds to the position of the label in the width direction of the conveyor belt, so that the label on the conveyor belt passes through the limiting groove 2039 when the conveyor belt passes through the through groove, thereby ensuring that the label attached to the conveyor belt is in a more accurate position after being peeled off.

[0049] To facilitate the robotic arm 3 in picking up the peeled labels and to prevent the labels from falling directly downwards after being peeled from the conveyor belt, an adjusting block 2034 is also installed on the upright 200. The central axis of the adjusting block 2034 is on the same axis as the central axis of the water platform 2030, and the adjusting block 2034 is located in front of the water platform 2030. The adjusting block 2034 can reciprocate along its axis on the upright 200. The upper surface of the adjusting block 2034 is lower than the upper surface of the water platform 2030. When the adjusting block 2034 is close to the water platform 2030, the end of the adjusting block 2034 that is close to the water platform 2030 is close to the inclined surface 2031. At the same time, an optical fiber sensor 2036 is also embedded on the upper surface of the adjusting block 2034. The optical fiber sensor 2036 is located at the end of the adjusting block 2034 that is close to the water platform 2030. The optical fiber sensor 2036 is used to detect the labels peeled from the conveyor belt.

[0050] In this invention, as the conveyor belt moves forward, when the label attached to the conveyor belt enters the front end of the platform 2030, the adjusting block 2034 moves toward the platform 2030 and approaches the inclined surface 2031. As the label is peeled off from the conveyor belt, the fiber optic sensor 2036 detects the peeled label. When the label is completely peeled off from the conveyor belt, the label enters the adjusting block 2034 so that the robot arm 3 can pick up the peeled label.

[0051] In this invention, to prevent labels peeled from the conveyor belt from entering the adjusting block 2034 and then moving out from both sides of the adjusting block 2034, an opening groove can be formed on the upper surface of the conveyor belt. This allows the labels peeled from the conveyor belt to be restricted by the sides of the opening groove after entering the adjusting block 2034. Simultaneously, to ensure that the conveyor belt can smoothly pass between the adjusting block 2034 and the inclined surface 2031 when the adjusting block 2034 abuts against the inclined surface 2031, one end of the opening groove near the horizontal platform 2030 penetrates through the end face of the adjusting block 2034. When the upper surface of the adjusting block 2034 has an opening groove, the fiber optic sensor 2036 can be embedded in the bottom of the opening groove.

[0052] In this invention, in order to ensure the movement of the adjusting block 2034, a linear guide rail 2032 with the same axial direction as the movement direction of the adjusting block 2034 is also installed on the upright 200, and a slidable slider 2033 is installed on the linear guide rail 2032, and the adjusting block 2034 is fixedly installed on the slider 2033; at the same time, a linear drive element 2035 is also installed on the upright 200, which is a cylinder or a hydraulic cylinder, and the output end of the linear drive element 2035 is connected to the slider 2033 or the adjusting block 2034.

[0053] In this invention, such as Figure 5As shown, the robotic arm 3 includes a robotic arm 300 mounted on the base 1. The robotic arm 300 is a direct use of an existing robotic arm 300, and the output end of the robotic arm 300 is equipped with a suction cup 301. Through the cooperation of the suction cup 301 and the robotic arm 300, the label peeled off from the material strip at the front end of the platform 2030 can be picked up by the suction cup 301 and transferred to the car key to be labeled in the fixed station 5, so that the label is attached to the car key.

[0054] In this invention, in order to identify the label area on the car key, the output end of the robotic arm 3 is also equipped with a mounting bracket 302, and a detection camera 303 is also mounted on the mounting bracket 302. In order to avoid the image acquisition results of the detection camera 303 being affected by insufficient light, a light source 304 for providing light to the detection camera 303 can also be mounted on the mounting bracket 302.

[0055] In this invention, in order to ensure the rotation of the turntable 4, a second drive motor 11 is also installed on the base 1. A reducer 12 is also installed at the output end of the second drive motor 11. The turntable 4 is installed at the output end of the reducer 12. At this time, the fixed plate 10 can be supported on the housing of the reducer 12 through the central hole of the center of the turntable 4 via the support base.

[0056] In this invention, such as Figure 6 , Figure 7 As shown, the loading and inspection module 6 includes an infrared sensor 600 and two fiber optic sensors 601 mounted on a mounting plate 10 and a base 1 via a bracket. The infrared sensor 600 is located above the fixed station 5, and the two fiber optic sensors 601 correspond to the two sides of the fixed station 5, respectively, and the two fiber optic sensors correspond to the two ends of the fixed station 5. When the fixed station 5 for placing car keys is aligned with the loading and inspection module 6 by the rotation of the turntable 4, the infrared sensor 600 located above the fixed station 5 is used to detect whether a car key is placed in the fixed station 5, and the fiber optic sensors 601 located on both sides of the fixed station 5 are used to detect whether the placed car key is kept flat. Therefore, in this invention, in order to facilitate the placement of the car key on the fixed station 5, and to facilitate the detection of the car key in the fixed station 5 by the infrared sensor 600 and the two fiber optic sensors 601, the fixed station 5 can be designed with a U-shaped base, and a groove adapted to the outer contour of the car key is opened on the upper surface of the base. This groove is the fixed station 5. At the same time, a through groove corresponding to the fiber optic sensor 601 is opened on the side of the base. The through groove not only penetrates the groove, but also penetrates the two opposite sides of the base.

[0057] In this invention, such as Figure 8As shown, the label pressing module 7 includes a frame 700, which is L-shaped. The vertical part of the frame 700 is fixed on the fixed plate 10. A linear drive element 701 is installed on the horizontal section of the frame 700. The output end of the linear drive element 701 extends vertically downward. The linear drive element 701 is a cylinder or a hydraulic cylinder. A pressure head 704 is also installed on the output end of the linear drive element 701. When a car key with a label is inserted under the pressure head 704 and needs to be pressed and fixed, the second linear drive element 701 extends and drives the pressure head 704 downward, pressing the pressure head 704 onto the label, thus fixing the label onto the car key. After the label is pressed and fixed onto the car key, the second linear drive element 701 retracts, simultaneously driving the pressure head 704 upward, moving the pressure head 704 away from the car key. At this time, the rotation of the turntable 4 allows the car key with the label pressed and fixed to enter the detection area of ​​the label detection module 8.

[0058] To ensure smoother up-and-down movement of the pressure head 704 and prevent misalignment of the label on the car key due to vibration when pressing down on the label, a vertically extending linear guide rail 706 is installed on the horizontal section of the frame 700. A sliding slider 707 is also installed on the linear guide rail 706. Meanwhile, a mounting base 702 is installed at the output end of the linear drive element 701, and the pressure head 704 is detachably mounted on the mounting base 702. The slider 707 is then fixed to the mounting base 702. When the linear drive element 701 drives the fixed seat 702 and the pressure head 704 to move, the fixed seat 702 drives the slider 707 to slide along the linear guide rail 706. This allows the fixed seat 702 and the pressure head 704 to be guided during movement through the cooperation of the linear guide rail 706 and the slider 707. This makes the movement of the fixed seat 702 and the pressure head 704 more stable and effectively prevents the pressure head 704 from causing the label to shift on the car key due to vibration when pressing the label.

[0059] To facilitate the replacement of the pressure head 704, a through groove 703 is provided on the lower surface of the fixed base 702. The through groove 703 is T-shaped, and one end of the through groove 703 and the slider 707 are both located on the same side of the fixed base 702. The top of the pressure head 704 has a plug 705, and the shape of the plug 705 is adapted to the shape of the through groove 703. When the pressure head 704 needs to be installed on the fixed base 702, the plug 705 can be inserted into the through groove 703 from one end, so that the pressure head 704 and the fixed base 702 can be connected. To prevent the pressure head 704 from vibrating on the fixed seat 702, one end of the slider 707 can extend to one end of the through groove 703. After the connector 705 is inserted into the through groove 703, the slider 707 can restrict one end of the connector 705. At the same time, a rotatable connecting rod 708 is also installed on the side of the fixed seat 702. The connecting rod 708 and the slider 707 are located on opposite sides of the fixed block, and the extended end of the connecting rod 708 has a threaded hole. The axis of the threaded hole is consistent with the axis of the through groove 703, and the threaded hole corresponds to the other end of the through groove 703. A locking bolt 709 is installed in the threaded hole. By tightening the locking bolt 709, the tail of the locking bolt 709 can press against the connector 705, thereby pressing the connector 705 between the slider 707 and the locking bolt 709, thus fixing the pressure head 704.

[0060] When the pressure head 704 needs to be replaced, turn the locking bolt 709 in the reverse direction so that the tail of the locking bolt 709 is away from the connector 705. Then, rotate the connecting rod 708 so that the connecting rod 708 is above the fixed seat 702. The operator can then pull the connector 705 on the pressure head 704 out of the through groove 703. Next, take the replaced pressure head 704 and insert the connector 705 on the upper part of the pressure head 704 into one end of the through groove 703. After the connector 705 is in place, turn the connecting rod 708 downward and tighten the locking bolt 709 so that the tail of the locking bolt 709 is pressed against the end face of the connector 705.

[0061] In this invention, the labeling detection module 8 includes a lifting cylinder 800, which is mounted on a fixed plate 10 via a bracket. A detection camera 801 is installed at the output end of the lifting cylinder 800. The detection camera 801 detects the position of the pressed and fixed label on the car key, thereby ensuring the positional accuracy of the label on the car key. To avoid insufficient lighting affecting the image acquisition results of the detection camera 801, a light source 802 for providing illumination to the detection camera 801 can also be installed at the output end of the lifting cylinder 800.

[0062] In this invention, the unloading module 9 includes a base frame 900 supported on the base 1, a top frame 902 above the base frame 900, multiple guide sleeves installed on the base frame 900, and a guide rod penetrating the guide sleeves installed on the top frame 902. The unloading module 9 also includes a second lifting cylinder 901 installed on the base 1. The output end of the second lifting cylinder 901 extends vertically upward and is fixed to the top frame 902. A rotary cylinder 903 is installed on the top frame 902, and an extension arm 904 is installed at the output end of the rotary cylinder 903. A pneumatic gripper 905 is installed at the extension end of the extension arm 904. The pneumatic gripper 905 can clamp the car key after labeling and testing at the fixed station 5 and transfer the clamped car key into the material box 13.

[0063] Furthermore, in order to collect the car keys held by the pneumatic gripper 905 in the material box 13, the material box 13 can be placed directly on the machine base 1. When the material box 13 is placed, the opening of the material box 13 is located below the movement trajectory of the pneumatic gripper 905. After the pneumatic gripper 905 clamps the car key in the fixed station 5, the rotary cylinder 903 drives the extension arm 904, so that the gripper cylinder and the clamped car key enter above the opening of the material box 13. In conjunction with the lifting cylinder 901, the top frame 902, the rotary cylinder 903, the extension arm 904, and the pneumatic gripper 905 move downward. Finally, the pneumatic gripper 905 releases the grip on the car key, so that the car key automatically falls into the material box 13.

[0064] When it is necessary to label car keys, the worker installs a spool of tape with the label attached onto the reel 201, and pulls the tape around the guide roller assembly 202 and the feed roller 2037. The tape then adheres to the horizontal platform 2030 and passes between the horizontal platform 2030 and the cover plate 2038 before being led out from the front end of the horizontal platform 2030. Next, the tape is folded downwards, and after adhering to the inclined surface 2031, it passes between the traction roller 2041 mounted on the U-shaped frame 2043 and the traction roller 2041 supported on the two mounting seats 2040. The end of the tape is then wound around the take-up roller 205. Finally, the flip plate 2047 is flipped downwards. As the tilting plate 2047 tilts downward, the rollers 2048 on the tilting plate 2047 push the adjusting bolts 2045 toward the U-shaped frame 2043. The telescopic spring 2046 is compressed, and the adjusting bolts 2045 push the U-shaped frame 2043, causing the traction rollers 2041 on the U-shaped frame 2043 to move closer to the traction rollers 2041 supported on the two mounting seats 2040. This causes the traction rollers 2041 on the U-shaped frame 2043 to press against the traction rollers 2041 supported on the two mounting seats 2040, thereby clamping the material strip between the traction rollers 2041 on the U-shaped frame 2043 and the traction rollers 2041 supported on the two mounting seats 2040.

[0065] A worker or robot places the car key to be labeled in a fixed station 5 located below the infrared sensor 600. After the car key is placed in the fixed station 5, the infrared sensor 600 and two fiber optic sensors 601 simultaneously detect the car key in the fixed station 5. Specifically, the infrared sensor 600 detects whether a car key is placed in the fixed station 5, and the two fiber optic sensors 601 detect whether the two ends of the placed car key are flat. After detecting that there is a car key in the fixed station 5 and that the car key is flat in the fixed station 5, the drive motor 11 rotates 90°. The drive motor 11 drives the turntable 4 to rotate 90° through the reducer 12. As the turntable 4 rotates, it pulls the car key placed in the fixed station 5 into the working range of the robotic arm 300. The robotic arm 300 moves the suction cup 301, the detection camera 303, and the light source 304, and moves the detection camera 303 above the car key to be labeled. The detection camera 303 collects data on the labeling area on the car key.

[0066] During this process, drive motor 206 drives the traction rollers 2041 and take-up roller 205 mounted on the two mounting bases 2040 to rotate. The traction rollers 2041, supported on the two mounting bases 2040, rotate simultaneously with the traction rollers 2041 on the U-shaped frame 2043, pulling the material belt forward. As the belt moves forward, the material tray on the reel 201 unwinds due to the traction of the belt, and the take-up roller 205 winds the belt. During this forward movement, the label attached to the belt moves forward synchronously, allowing the label to pass through the limiting groove 2039 on the cover plate 2038 and enter the front end of the horizontal platform 2030. At this time, the linear drive element... 2035 drives the adjusting block 2034 to approach the inclined surface 2031. When the part of the material belt with the label attached is led out from the front end of the water platform 2030 and folded downward, the label attached to the material belt has a certain hardness, so when the material belt folds at the front end of the water platform 2030, the label attached to the material belt is separated at the same time as the material belt folds. The separated label is guided forward by the material belt and eventually separates from the material belt and enters the adjusting block 2034. The fiber optic sensor 2036 on the adjusting block 2034 detects the separated label, and the linear drive element 2035 retracts and drives the adjusting block 2034 to reset, preparing for the suction cup 301 to pick up the label.

[0067] Next, the robotic arm 300 moves the suction cup 301, the detection camera 303, and the light source 304, causing the suction cup 301 to move above the adjustment block 2034 and pick up the separated label. The robotic arm 300 moves the suction cup 301, the detection camera 303, the light source 304, and the picked-up label, and attaches the picked-up label to the car key. Then, the suction cup 301 releases its grip on the label, and the robotic arm 300 moves the suction cup 301, the detection camera 303, and the light source 304 upward. The light source 304 provides illumination for the detection camera 303, which is ready to collect data on the labeling area of ​​the car key to be labeled at the next fixed station 5.

[0068] The second drive motor 11 rotates 90° again, and the second drive motor 11 drives the turntable 4 to rotate 90° through the reducer 12. While the turntable 4 is rotating, it drives the car key with the label placed in the fixed station 5 to enter under the label pressing module 7. Then, the second linear drive element 701 extends and drives the fixed seat 702 and the pressing head 704 to move downward, so that the pressing head 704 presses the label on the car key, and the label is pressed and fixed on the car key. After the label is pressed and fixed on the car key, the second linear drive element 701 retracts and drives the fixed seat 702 and the pressing head 704 to move upward. The pressing head 704 moves away from the car key, and the car key is labeled.

[0069] Drive motor 11 rotates 90° again, and drive motor 11 drives turntable 4 to rotate 90° through reducer 12. As turntable 4 rotates, it pulls the car key placed in fixed station 5 (where the label has been applied) into the detection range of labeling detection module 8. Lifting cylinder 800 retracts, and lift cylinder 800 drives detection camera 801 and light source 802 to move downwards synchronously. Light source 802 provides illumination for detection camera 801. Detection camera 801 detects the position of the pressed and fixed label on the car key. After detection camera 801 passes the test, lifting cylinder 800 extends, and lift cylinder 800 drives detection camera 801 and light source 802 to move upwards synchronously. Then, pneumatic gripper 905 opens, and rotary cylinder 903 drives extension arm 904 and pneumatic gripper 905 to move, allowing pneumatic gripper 905 to enter the car key where the label has been applied. Above the car key; then, lifting cylinder 2 901 retracts, driving rotating cylinder 903, extension arm 904, and pneumatic gripper 905 downwards, aligning the pneumatic gripper 905 with the labeled car key; the pneumatic gripper 905 closes to clamp the labeled car key, lifting cylinder 2 901 extends and drives rotating cylinder 903, extension arm 904, and pneumatic gripper 905 downwards; rotating cylinder 903 drives extension arm 904, pneumatic gripper 905, and the clamped car key to move, bringing the labeled car key above the opening of material box 13; lifting cylinder 2 901 retracts, driving rotating cylinder 903, extension arm 904, pneumatic gripper 905, and the clamped car key downwards, finally, the pneumatic gripper 905 opens, causing the car key clamped by the pneumatic gripper 905 to automatically fall into material box 13.

[0070] Finally, drive motor 21 rotates 90° again. Drive motor 211 drives turntable 4 to rotate 90° through reducer 12. While the turntable 4 is rotating, it drives the fixed station 5, which has already had the car key removed, into the detection range of loading and detection module 6, and repeats the above steps.

[0071] Those skilled in the art should understand that the above embodiments are merely for illustrating the present invention and are not intended to limit the scope of the invention. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present invention.
