Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing and automation technology, specifically a one-stop workpiece surface label drying and blowing device. Background Technology

[0002] In the production process of electronic product components such as laptop casings, removing the transparent plastic label from a specific area (the logo area) on the workpiece surface is a critical step. These labels are thin and lightweight, requiring gentle and precise handling to avoid damaging the markings on the workpiece surface, thus ensuring product appearance quality and brand consistency. Currently, the industry commonly uses a drying process, employing multiple blowers to deliver gentle airflow and gradually peel off the label. Laser positioning assists in manual loading to ensure precise alignment of the label with the drying area.

[0003] However, the existing operation mode relies on manual feeding. When workers manually place the laptop casings, it is difficult to continuously and accurately control the position of the workpiece on the conveyor belt. Affected by factors such as operating habits and fatigue, the workpiece is prone to tilting and shifting, and cannot be stably positioned in the middle of the conveyor belt and directly below the drying air outlet. Positional deviation leads to uneven airflow during drying, with excessive or insufficient airflow in some areas. This not only reduces the label peeling efficiency but also greatly increases the risk of the logo being blown away, affecting product yield and production efficiency, becoming a pain point restricting the stable and efficient operation of this process. Therefore, we propose a one-stop workpiece surface label drying and blowing device to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a one-stop workpiece surface label drying and blowing device to solve the problem mentioned in the background art that in the production of workpiece surface labels, the drying and blowing process for removing the transparent label paper at the LOGO area relies on manual feeding. Because it is difficult for workers to continuously and accurately control the position of the workpiece, it is easy for it to tilt or shift, resulting in uneven drying and blowing airflow. This not only reduces the label peeling efficiency but also increases the risk of LOGO damage, thus restricting the stability and efficiency of the process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A one-stop workpiece surface label drying and blowing device includes a conveyor frame for drying and blowing workpiece labels and a centering positioning component for conveying and centering the workpiece. The conveyor frame includes a frame body and conveying rollers evenly distributed inside the frame body. The positioning component is located inside the frame body below the conveying rollers. The centering positioning component includes a driving component, a guiding component, and a positioning component. The positioning component includes a positioning plate arranged in a symmetrical structure and positioning uprights evenly distributed on the top of the two positioning plates. The positioning plates are perpendicular to the conveying rollers, and the top of each positioning upright passes through the gap between the two conveying rollers and extends above it.

[0006] Preferably, the guide includes a symmetrically arranged support base plate, a support top plate, guide rails, and sliding blocks slidably located on the guide rails. The support base plate is parallel to the bottom of the conveyor roller and its two ends are connected to the inner walls of both sides of the frame. The guide rails are symmetrically distributed parallel to each of the support base plates near the top of both ends. The support top plate is installed on the top of the two support base plates between the guide rails. The bottom of both ends of the positioning plate is fixed to the sliding blocks at the top of the two guide rails near it.

[0007] Preferably, the driving component includes a swing plate, a connecting rod, and an electric telescopic rod. The bottom center of the swing plate is rotatably connected to the top of the supporting top plate via a rotating shaft. The connecting rod is symmetrically connected to both ends of the swing plate. The other end of the connecting rod is rotatably connected to the middle of the nearby positioning plate via a rotating shaft.

[0008] Preferably, the electric telescopic rod is installed in a symmetrical structure on the outer walls of two supporting base plates, and the output end of the electric telescopic rod is connected to the positioning plate adjacent to it.

[0009] Preferably, a drying component is installed on the top of the frame. The drying component includes a fixed frame installed parallel to the top center of the frame, a transverse guide rail, and multiple sets of slidable hot air guns. The transverse guide rail is arranged along the length of the fixed frame and fixed to its bottom. The multiple sets of hot air guns are slidably suspended on the transverse guide rail and correspond to the area above the positioning pole.

[0010] Preferably, the electric telescopic rod and the conveying roller are linked to an external control device via wires.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This application provides precise and stable positioning, solving the problem of deviation in manual feeding. When the workpiece on the conveyor roller is centered, the electric telescopic rod retracts to pull the positioning plate and the top positioning rod to move towards the center simultaneously. With the help of the symmetrical positioning rod, a uniform clamping force is formed on the workpiece, which can accurately adjust the workpiece to the center of the conveyor roller. This mechanically driven synchronous positioning method avoids the problem of workpiece tilting and offset caused by differences in operation during manual feeding, and provides a stable positional basis for the subsequent drying and blowing process.

[0012] 2. The highly efficient structural linkage enhances the smoothness of process connections. The guide rails and sliding blocks of the guide components provide stable guidance for the movement of the positioning plate. Combined with the linkage structure of the swing plate and connecting rod in the drive components, the synchronicity and stability of the positioning pole's movement are ensured. Simultaneously, the electric telescopic rod and conveyor rollers are linked with external control equipment signals, automatically triggering the conveying action after positioning is completed, reducing manual intervention and improving the overall process efficiency.

[0013] 3. Strong adaptability to drying and blowing, ensuring label removal quality. The multiple sets of hot air guns in the drying and blowing component can be manually adjusted and slid along the horizontal guide rail, and correspond to the area above the positioning pole. Since the workpiece is precisely positioned in the preset drying and blowing position, the hot air gun can form a uniform and concentrated drying and blowing effect on the label paper at the logo of the workpiece. Combined with the design of multiple sets of hot air guns, it can not only efficiently peel off the label paper, but also avoid excessive local air force concentration caused by position deviation, reduce the risk of the logo being blown out, and ensure the appearance quality of the product.

[0014] 4. Wide applicability and excellent flexibility: The sliding design of the horizontal guide rail allows the hot air gun to be adjusted according to the logo position of different workpieces, meeting the label blowing needs of workpieces such as laptop casings of various sizes. Simultaneously, the drive stroke of the electric telescopic rod can be flexibly adjusted via external control equipment, adapting to the positioning of workpieces of different sizes and improving the device's versatility.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see the appendix Figure 1 - Figure 5 As shown, a one-stop workpiece surface label drying and blowing device includes a conveyor frame 1 for drying and conveying workpiece labels, a centering positioning component 2 for conveying and centering the workpiece, and a drying and blowing component 3. The components work together to realize the conveying, positioning, and label drying and blowing operations of the workpiece. The conveyor frame 1 includes a frame body 11 and conveying rollers 12 evenly distributed inside the frame body 11. The conveyor frame 1 serves as the basic load-bearing structure. The conveying rollers 12 are evenly distributed inside the frame body 11, and the workpiece is placed on the conveying rollers 12 to complete the conveying. The centering positioning component 2 includes a driving component 21, a guiding component 22, and a positioning component 23. The centering positioning component 2 is located inside the frame body 11 below the conveying rollers 12.

[0019] The positioning component 23 includes a positioning plate 231 arranged in a symmetrical structure and positioning rods 232 evenly distributed on the top of the two positioning plates 231. The positioning plates 231 are perpendicular to the conveying rollers 12. The top of each positioning rod 232 passes through the gap between the two conveying rollers 12 and extends above it. The symmetrical positioning plates 231 of the positioning component 23 are perpendicular to the conveying rollers 12. The top positioning rods 232 pass through the gap between the conveying rollers 12 and extend above it, and can directly contact the bottom of the workpiece.

[0020] The guide member 22 includes a symmetrically arranged support base plate 221, support top plate 222, guide rail 223, and sliding block 224 slidably located on the guide rail 223. The support base plate 221 is parallel to the bottom of the conveying roller 12 and its two ends are connected to the inner walls of both sides of the frame 11. The guide rail 223 is symmetrically distributed parallel to each support base plate 221 near the top of both ends. The support top plate 222 is installed on the top of the two support base plates 221 between the guide rails 223. The bottom of both ends of the positioning plate 231 is fixed to the sliding block 224 on the top of the two guide rails 223 that are close to it. The support base plate 221 of the guide member 22 is fixed to the inner wall of the frame 11. The guide rail 223 and the sliding block 224 provide sliding guidance for the positioning plate 231. The support top plate 222 provides the mounting base for the drive member 21.

[0021] The driving component 21 includes a swing plate 211, a connecting rod 212, and an electric telescopic rod 213. The bottom center of the swing plate 211 is rotatably connected to the top of the supporting top plate 222 via a rotating shaft. The connecting rod 212 is symmetrically connected to both ends of the swing plate 211. The other end of the connecting rod 212 is rotatably connected to the middle of the nearby positioning plate 231 via a rotating shaft. The electric telescopic rod 213 is symmetrically installed parallel to the outer walls of the two supporting bottom plates 221. The output end of the electric telescopic rod 213 is connected to the nearby positioning plate 231. The swing plate 211 of the driving component 21 is connected to the supporting top plate 222 via a rotating shaft, and both ends are linked to the positioning plate 231 via the connecting rod 212. Together with the electric telescopic rod 213 on the outer wall of the supporting bottom plate 221, a stable driving structure is formed. The electric telescopic rod 213 and the conveying roller 12 are linked to the signal of the external control equipment via wires.

[0022] When the workpiece is centered, the electric telescopic rod 213 retracts, and through the linkage of the connecting rod 212 and the swing plate 211, it pulls the positioning plates 231 on both sides to move synchronously towards the center along the guide rail 223. The positioning upright 232 then forms a symmetrical clamp on the workpiece on the conveyor roller 12, completing the centering adjustment. After positioning, because the electric telescopic rod 213 and the conveyor roller 12 are linked with the external control equipment, the conveyor roller 12 automatically starts to transport the workpiece to the drying area.

[0023] Please see the appendix Figure 1 and Figure 6 As shown, a drying and blowing component 3 is installed on the top of the frame 11. The drying and blowing component 3 includes a fixed frame 31 installed parallel to the top center of the frame 11, a transverse guide rail 32, and multiple sets of slidable hot air guns 33. The transverse guide rail 32 is arranged along the length of the fixed frame 31 and fixed to its bottom. The multiple sets of hot air guns 33 are slidably suspended on the transverse guide rail 32 and correspond to the area above the positioning pole 232. The drying and blowing component 3 at the top of the frame 11 is responsible for the label removal operation. The transverse guide rail 32 at the bottom of the fixed frame 31 is arranged along the conveying direction. The multiple sets of hot air guns 33 are slidably suspended on the guide rail and correspond to the area above the positioning pole 232, which can accurately align with the label at the workpiece LOGO and peel off the label through hot air flow.

[0024] Workflow: The laptop casing workpiece to be processed is placed at the starting end of the conveyor roller 12 of the conveyor frame 1. A certain deviation is allowed in the initial position of the workpiece. The conveyor roller 12 is in standby mode at this time, waiting for the positioning signal to be triggered. After the external control device detects that the workpiece has been placed on the conveyor roller 12, it sends a start signal to the electric telescopic rod 213 of the centering positioning member 2. After receiving the signal, the electric telescopic rod 213 retracts and drives the swing plate 211 to rotate around the pivot of the supporting top plate 222 through the connecting rod 212. The connecting rods 212 on both sides simultaneously pull the positioning plate 231. Under the constraint of the guide rail 223 and the sliding block 224 of the guide member 22, the positioning plate 231 slides smoothly towards the center in a direction perpendicular to the conveyor roller 12. The positioning upright 232 at the top passes through the gap of the conveyor roller 12 and forms symmetrical positions with respect to the bottom of the workpiece on both sides. The electric telescopic rod 213 receives the reset signal and extends, which is linked with the swing plate 211 through the connecting rod 212. The positioning plate 231 and positioning rod 232 are moved back to their initial positions to wait for the next workpiece to be loaded and positioned, and then the next work cycle begins. The external control device receives the positioning signal and the conveyor roller 12 moves the centered workpiece along the conveying direction until the workpiece is conveyed to the drying area directly below the drying component 3. At this time, the label on the workpiece's logo is precisely aligned with the area below the hot air gun 33. The multiple sets of hot air guns 33 of the drying component 3 are pre-adjusted along the transverse guide rail 32 to the position corresponding to the workpiece's logo label (they can be pre-calibrated according to different workpiece specifications). The external control device triggers the hot air gun 33 to start, and the transparent plastic label on the workpiece's logo is dried and blown by a gentle hot airflow. The label is gradually peeled off by the uniform force of the hot airflow. After the label is completely peeled off, the hot air gun 33 stops working, and the conveyor roller 12 conveys the processed workpiece to the end of the conveyor frame 1. The operator or subsequent equipment then removes the workpiece.

[0025] This application achieves integrated processing from workpiece placement to label peeling through fully automated connection of "conveying and feeding - positioning - resetting - conveying - drying and blowing", eliminating the need for manual intervention in positioning and drying and blowing alignment, and greatly improving operational stability.
