Description

Technical Field

[0001] This utility model relates to an automatic labeling and scanning assembly equipment for automotive electric door and window switches, belonging to the field of automobile manufacturing. Background Technology

[0002] With the rapid development of the automotive industry, the types and quantities of in-vehicle electric switches are constantly increasing, and their functions cover multiple aspects such as window control, headlight control, and seat adjustment. To ensure production consistency and information traceability, switches typically require labeling and barcode scanning after assembly to achieve product information management and quality traceability.

[0003] Currently, the industry commonly uses manual labeling and barcode scanning for production. Due to the small size of the switch body, the space for labeling is limited, especially when the label size is only 10mm×10mm. Manual operation has the following drawbacks: poor labeling accuracy—small labels are difficult to position accurately in limited space, easily resulting in offset or curling edges, affecting product appearance and recognition rate; low production efficiency—manual labeling and scanning are slow and cannot meet the needs of mass production; high error rate—workers are prone to fatigue from repetitive operations, leading to incorrect or missing labels and increased rework rates; difficulty in traceability—manual barcode scanning is inefficient and prone to omissions, failing to guarantee data integrity and affecting subsequent product information traceability; and high production costs—the large investment of manpower not only increases labor costs but also creates management and training pressures.

[0004] While some semi-automatic labeling equipment exists in the current technology, it is mostly designed for medium to large-sized labels. For small labels such as 10mm x 10mm, it suffers from difficulties in label dispensing, peeling, and large label placement deviations, making it difficult to meet the miniaturization and precision production requirements of automotive switches. Furthermore, existing equipment lacks versatility and cannot accommodate the labeling needs of different switch models, limiting its widespread application. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide an automatic labeling and scanning assembly device for automotive electric door and window switches, which aims to solve the problems of difficulty and low efficiency in applying small automotive labels.

[0006] An automatic labeling and barcode scanning assembly device for automotive electric door and window switches includes a frame, on which are mounted automatic labels and barcode scanners. The label printing unit is used to generate labels with information. The feeding unit is used for loading and storing products. Pick-and-carry unit is used to pick up and transport products to the labeling location; The positioning unit is used to fix the product picked up by the pick-and-carry unit; The control unit is electrically connected to each unit and is used to control the actions of each unit. The frame is also equipped with a labeling unit, which includes a labeling robot. The labeling robot is used to pick up the labels from the printing and labeling unit and attach them to the products on the positioning unit.

[0007] This technical solution enables the labeling robot, in conjunction with a precision positioning unit, to achieve stable clamping and high-precision positioning of the products to be labeled. This ensures accurate placement of small-sized labels within a limited space, preventing offset, misalignment, and curling, significantly improving appearance pass rate and barcode recognition rate. A closed-loop control and visual verification system (optional camera or sensor) linking the printing and labeling unit and the labeling robot allows for real-time correction of the labeling position, ensuring labeling consistency across batches. Automated loading, picking, handling, and labeling processes replace manual piece-by-piece operations, ensuring continuous and stable operation and significantly increasing output per unit time to meet the demands of mass production. Automated and precise labeling reduces errors, omissions, or positional deviations caused by human fatigue, lowering rework and defect rates.

[0008] Preferably, the labeling unit further includes a vision guidance component mounted on the labeling robot. The vision guidance component includes a camera and a vision analysis system electrically connected to the control unit. The vision analysis system is used to analyze the images captured by the camera and control the labeling robot to accurately pick up the label and attach it to the product.

[0009] This technical solution uses a camera to capture the position and orientation information of small labels on the printing and labeling unit in real time. The vision analysis system processes the images and feeds back the actual label position data to the control unit, guiding the labeling robot to pick up the labels precisely and avoiding pickup failures caused by label offset or rotation. During the labeling process, the vision guidance system can also detect minute errors in product positioning and dynamically correct the labeling trajectory to ensure accurate label placement. For small labels such as 10mm×10mm, manual or traditional mechanical methods struggle to guarantee consistent label placement each time. The vision guidance system, however, can maintain a high degree of consistency in the position of each label through real-time correction, improving product appearance and quality.

[0010] Furthermore, the picking and handling unit includes a four-axis robot, which is equipped with actuators for grasping products.

[0011] This technical solution enables four-axis robots to move quickly and respond responsively, allowing them to pick up and move products in a short time, improving the overall production line cycle time and meeting the needs of mass production. The actuators can be designed as vacuum nozzles, grippers, or customized claws to suit the shape of the switch products, achieving flexible clamping that ensures reliable gripping while reducing the risk of damage to small, precision products.

[0012] Preferably, the positioning unit includes a fixed plate fixed on the frame, the fixed plate is provided with a mounting position for placing the product, and grippers are provided on both sides of the mounting position. The grippers are rotatably mounted on a clamping drive component, and the clamping drive component is used to drive the grippers to rotate and clamp the mounted product.

[0013] This technical solution defines the basic position of the product by fixing the mounting position on the plate, preventing the product from shifting after handling and placement; the stable clamping keeps the product in a constant posture within the positioning unit, preventing label misalignment or scanning failure due to unstable product position, thus improving the overall labeling and recognition accuracy.

[0014] Preferably, the feeding unit includes a vertical storage bin, on which a plurality of spaced-apart mounting trays are installed. Chain belts are provided on both sides of the vertical storage bin, and mounting frames are provided on the chain belts. The mounting frames are provided with a pulling drive component for pulling out a mounting tray.

[0015] This technical solution allows the vertical storage bin to hold multiple mounting trays within a limited space, achieving large-capacity product storage, avoiding frequent manual replenishment, and improving production continuity. The coordination between the chain conveyor and the mounting frame enables the mounting trays to be pushed out one by one, forming a stable and controllable feeding process and ensuring production line cycle time. Through a pull drive component (such as a motor drive or cylinder drive) mounted on the mounting frame, a designated mounting tray can be pulled out individually, preventing multiple trays from jamming or misaligning simultaneously, ensuring the accuracy and reliability of the feeding action.

[0016] Furthermore, the mounting bracket is provided with a slide rail, and the slide rail is provided with a pull drive component that cooperates with the mounting plate.

[0017] With this technical solution, the pull drive component can achieve high-speed and stable linear reciprocating motion under the guidance of the slide rail, which helps to further shorten the single feeding time and improve the overall production efficiency.

[0018] Preferably, the frame is further provided with a detection unit, which includes a feeding robot. The feeding robot is equipped with a visual inspection sensor for detecting the labeling quality of the products. The visual inspection sensor is used to collect the labeling quality of the products and transmit it to the control unit, which then controls the feeding robot to sort qualified and unqualified products.

[0019] This technical solution utilizes visual inspection sensors deployed on the unloading robot to perform real-time inspections of labeling position, flatness, integrity, and QR code / barcode clarity before product unloading, achieving end-to-end quality control. Inspection data is directly fed back to the control unit, automatically distinguishing between qualified and unqualified products, ensuring that every product leaving the factory undergoes quality screening, thus improving overall consistency and reliability. Compared to manual inspection, visual inspection sensors are unaffected by fatigue or subjective differences, enabling stable, fast, and accurate labeling quality judgment, reducing missed detections and misjudgments.

[0020] Preferably, the control unit includes an operation screen mounted on a rack, the operation screen being used to collect and control information from each unit.

[0021] This technical solution integrates the operation panel and control unit, enabling centralized collection of operational information from various units (printing and labeling, feeding, picking and handling, positioning, labeling, detection, and unloading, etc.) to achieve unified monitoring and scheduling, thereby improving the overall machine's collaborative efficiency. The operation panel provides an intuitive interface, allowing operators to conveniently start, stop, set parameters, and view operational status via touch or buttons, reducing reliance on specialized personnel.

[0022] The beneficial effects of this invention are as follows: The labeling robot, in conjunction with a precision positioning unit, can stably clamp and accurately position the product being labeled, ensuring accurate placement of small-sized labels within a limited space, avoiding offset, misalignment, and curling, and significantly improving the appearance pass rate and barcode recognition rate. The use of closed-loop control and visual verification (optional camera or sensor) linking the printing and labeling unit with the labeling robot enables real-time correction of the labeling position, ensuring consistency in labeling across batches. Automated feeding, picking, handling, and labeling processes replace manual piece-by-piece operation, ensuring continuous and stable operation and significantly increasing output per unit time, meeting the needs of mass production. Automated and precise labeling reduces errors, omissions, or positional deviations caused by human fatigue, lowering rework and defect rates. Attached Figure Description

[0028] like Figure 1-5 The image shows an embodiment of an automatic labeling and scanning assembly device for automotive electric door and window switches according to this utility model. It includes a frame 1, on which are provided... The label printing unit 72 is used to generate labels with information. Feeding unit 3 is used for product feeding and storage; Pick-and-transfer unit 4 is used to pick up and transport the product to the labeling position; Positioning unit 5 is used to fix the product picked up by picking and handling unit 4; Control unit 6 is electrically connected to each unit and is used to control the operation of each unit. The frame 1 is also equipped with a labeling unit 7, which includes a labeling robot 71. The labeling robot 71 is used to pick up the label from the printing and labeling unit 72 and attach it to the product on the positioning unit 5.

[0029] This technical solution utilizes a labeling robot 71, in conjunction with a precision positioning unit 5, to achieve stable clamping and high-precision positioning of the product being labeled. This ensures accurate placement of small-sized labels within a limited space, preventing offset, misalignment, and curling, significantly improving appearance pass rate and barcode recognition rate. A closed-loop control and visual verification system (optional camera or sensor) linking the printing and labeling unit 72 and the labeling robot 71 enables real-time correction of labeling positions, ensuring consistent labeling across batches. Automated feeding, picking, handling, and labeling processes replace manual piece-by-piece operations, ensuring continuous and stable operation and significantly increasing output per unit time to meet the demands of mass production. Automated and precise labeling reduces errors, omissions, or positional deviations caused by human fatigue, lowering rework and defect rates.

[0030] The labeling unit 7 also includes a visual guidance component 72 disposed on the labeling robot 71. The visual guidance component 72 includes a camera and a visual analysis system electrically connected to the control unit 6. The visual analysis system is used to analyze the images captured by the camera and control the labeling robot 71 to accurately pick up the label and then attach it to the product.

[0031] This technical solution uses a camera to capture the position and orientation information of small labels on the printing and labeling unit 72 in real time. After processing the images, the vision analysis system feeds back the actual position data of the labels to the control unit 6, thereby guiding the labeling robot 71 to pick them up precisely and avoiding picking failures caused by small labels being offset or rotated. During the labeling process, the vision guidance system can also detect minute errors in product positioning and dynamically correct the labeling trajectory to ensure accurate label placement. For small labels such as 10mm×10mm, manual or traditional mechanical methods cannot guarantee the consistency of labeling position every time. The vision guidance system can maintain a high degree of consistency in the position of each label through real-time correction, improving the product appearance and quality.

The clamping drive component 54 is used to drive the grippers 53 to rotate and clamp the installed product.

[0035] This technical solution defines the basic position of the product by the mounting position 52 on the fixing plate 51, preventing the product from shifting after handling and placement; the stable clamping keeps the product in a constant posture within the positioning unit 5, preventing label misalignment or scanning failure due to unstable product position, and improving the overall labeling and recognition accuracy.

Chain belts 33 are provided on both sides of the vertical storage bin 31, and mounting frames 34 are provided on the chain belts 33. The mounting frames 34 are provided with a pulling drive component 36 for pulling out a mounting disc 32.

[0037] This technical solution allows the vertical storage bin 31 to hold multiple mounting trays 32 within a limited space, achieving large-capacity product storage, avoiding frequent manual replenishment, and improving production continuity. The cooperation between the chain conveyor 33 and the mounting frame 34 enables the mounting trays 32 to be pushed out one by one, forming a stable and controllable feeding process and ensuring production line cycle time. Through the pulling drive component 36 (such as a motor drive or cylinder drive) installed on the mounting frame 34, a designated mounting tray 32 can be pulled out individually, preventing multiple trays from jamming or misaligning simultaneously, ensuring the accuracy and reliability of the feeding action.

[0038] The mounting bracket 34 is provided with a slide rail 35, and the slide rail 35 is provided with a pull drive component 36 that cooperates with the mounting plate 32.
