Description

Technical Field

[0001] This utility model relates to the technical field of automated equipment for power bank production, and in particular to an automatic product orientation coding device. Background Technology

[0002] In the mass production of power banks, automated production lines have become key to improving production efficiency and ensuring product consistency. Currently, power banks on the production line need to go through automatic weighing, labeling, lamination, and heat shrinking processes in sequence. After these processes, the products move continuously in the same fixed direction on the conveyor belt, and their posture and travel path remain stable.

[0003] However, in the subsequent coding process, the existing production process faces a significant technical bottleneck because the coding operation needs to be completed on the bottom of the power bank. Due to the influence of the previous process, the orientation of the product on the conveyor belt cannot directly meet the position requirements for bottom coding; the product must be turned 90° before coding can be performed. Currently, the main way to solve this problem is through manual intervention. A dedicated operator is stationed in front of the coding machine. Before the product is conveyed to the coding station, the operator manually rotates the product 90° to adjust it to the required position for coding, and then the coding machine completes the coding. This manual turning method wastes labor costs, has low production efficiency, and carries the risk of operational errors. Utility Model Content

[0004] This utility model aims to at least partially solve one of the problems in related technologies. Therefore, one objective of this utility model is to provide an automatic product-turning coding device, which enables power banks to automatically turn 90° during transport, completing bottom coding without manual intervention, thereby improving production efficiency, reducing labor costs, and ensuring the stability of coding quality.

[0005] An automatic product steering inkjet printing device includes a conveyor belt and an inkjet printer. The automatic product steering inkjet printing device also includes a first baffle, a second baffle, a third baffle, and a fourth baffle arranged in sequence. The first baffle is located near the starting end of the conveyor belt and is inclined to guide the product that enters the conveyor belt in a straight line to move in an inclined manner to one side and to the second baffle. The second baffle is disposed along the edge of the conveyor belt and is located on the product conveying path; when the first baffle guides the product to the position of the second baffle, the end of the second baffle abuts against the front edge of the product, so that the product automatically turns 90° around the front. The third baffle is located opposite the second baffle and is inclined. The space between the third baffle and the second baffle gradually decreases along the product conveying direction to form a width space that gradually adapts to the lateral movement of the product, which is used to guide the product after turning to the lateral conveying position. The fourth baffle is disposed behind the second baffle and opposite the third baffle along the conveying direction, and is disposed along the edge of the conveyor belt to maintain the conveying path of the product. The inkjet printer is positioned behind the fourth baffle to print codes on the guided products.

[0006] Furthermore, the first baffle, the second baffle, the third baffle, and the fourth baffle are all adjustable baffles. Each adjustable baffle includes an adjustable connecting seat, a connecting rod, and a baffle body. The adjustable connecting seat is connected to one side of the conveyor belt, and one end of the connecting rod is movably connected to the adjustable connecting seat, while the other end is connected to the baffle body.

[0007] Furthermore, the adjustable connecting seat includes a fixed part and a movable part. The fixed part is fixedly connected to one side of the conveyor belt, and the movable part is pivotally connected to the fixed part via a pivot. The movable part has a locking mechanism, and one end of the connecting rod is movably connected to the movable part.

[0008] Furthermore, the locking mechanism includes a knob and a fastening screw. The movable part has a threaded hole. The knob is connected to one end of the fastening screw, and the other end of the fastening screw is movably inserted through the threaded hole and abuts against the connecting rod.

[0009] Furthermore, a soft rubber layer is provided on the surface of the baffle body.

[0010] Furthermore, the end of the second baffle has an arc-shaped guide surface.

[0011] Furthermore, the space between the third baffle and the second baffle gradually decreases to form a converging channel, the minimum width of which matches the width of the product laterally.

[0012] Furthermore, a channel parallel to the edge of the conveyor belt is formed between the fourth baffle and the third baffle.

[0013] Furthermore, the inkjet printer is equipped with a sensor that detects the arrival position and status of the product and triggers the inkjet printer to perform precise inkjet printing.

[0014] Furthermore, the conveyor belt is 2000mm long and 400mm wide.

[0015] Compared with the prior art, the above-mentioned technical solution provided in this application has the following advantages: By setting a first baffle, a second baffle, a third baffle and a fourth baffle in sequence, this application uses a mechanical guiding structure to realize the automatic 90° turning of the product on the conveyor belt. The product posture can meet the bottom inkjet printing requirements without manual operation, which effectively saves labor costs, improves inkjet printing quality and production efficiency, and promotes the full automation process of power bank production lines.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] like Figure 1 - Figure 5 As shown, the automatic product steering inkjet printing device 1 provided in this application includes a conveyor belt 10 and an inkjet printer 20. The automatic product steering inkjet printing device also includes a first baffle 30, a second baffle 40, a third baffle 50 and a fourth baffle 60 arranged in sequence. The first baffle 30 is disposed near the starting end of the conveyor belt 10 and is inclined to guide the product 130 that enters the conveyor belt 10 in a straight line to move to one side at an angle and to the second baffle 40. The second baffle 40 is disposed along the edge of the conveyor belt 10 and is located on the conveying path of the product 130; when the first baffle 30 guides the product 130 to the position of the second baffle 40, the end of the second baffle 40 abuts against the front edge of the product 130 so that the product 130 automatically turns 90° around the front. The third baffle 50 is disposed opposite the second baffle 40 along the conveying direction and is inclined. The space between the baffle 50 and the second baffle 40 gradually decreases along the conveying direction of the product 130 to form a width space that gradually adapts to the lateral direction of the product 130, which is used to guide the product 130 after turning to the lateral conveying position. The fourth baffle 60 is disposed behind the second baffle 40 and opposite the third baffle 50, and is disposed along the edge of the conveyor belt 10 to maintain the conveying path of the product 130. The inkjet printer 20 is positioned after the fourth baffle 60 to print codes on the guided product 130.

[0023] In practical applications, the power bank product 130, after undergoing preliminary processes, enters along the starting end of the conveyor belt 10 and initially moves in a straight line along the conveyor belt 10. The first baffle 30 is located near the starting end of the conveyor belt 10 and is tilted inwards at a certain angle. When the product 130 contacts the first baffle 30, it gradually shifts to one side of the conveyor belt 10 under the guidance of the first baffle 30, moving in an inclined manner towards the second baffle 40. The second baffle 40 is fixed along the edge of the conveyor belt 10, positioned on the conveying path of the product 130 after being guided by the first baffle 30. When the product 130 reaches the second baffle 40 under the guidance of the first baffle 30, the end of the second baffle 40 just abuts against the front edge of the product 130. As the conveyor belt 10 continues to move, the product 130, resisted by the second baffle 40, rotates around the point of contact with the second baffle 40, achieving automatic turning and changing from the initial longitudinal state to a lateral state. The third baffle 50 is positioned opposite the second baffle 40 (i.e., on the other side of the conveyor belt 10) and is also inclined, forming a converging channel that gradually narrows along the conveying direction between it and the second baffle 40. The minimum width of this converging channel matches the lateral width of the product 130 after the turn, enabling precise guidance of the product 130 to the lateral conveying path of the conveyor belt 10 and ensuring the stability of the product 130's posture. The fourth baffle 60 is located behind the second baffle 40 and is positioned on both sides of the conveyor belt 10, forming a straight channel parallel to the edge of the conveyor belt 10. After being guided by the third baffle 50, the product 130 enters this channel and, under the combined action of the fourth baffle 60 and the third baffle 50, is stably conveyed to the coding station while maintaining a stable lateral posture. The coding printer 20 is installed behind the fourth baffle 60, with its coding nozzle aligned with the bottom of the product 130. The sensor 120, which is matched with the inkjet printer 20, is set in front of the inkjet nozzle. When the sensor 120 detects that the product 130 has reached the inkjet position and the posture meets the requirements, it immediately triggers the inkjet printer 20 to work and complete the precise inkjet printing on the bottom of the product 130.

[0024] In traditional production, a specialist is required to manually turn product 130 90° before coding, which not only incurs labor costs but also easily causes production line jams due to inconsistent operating speeds. In this solution, the first baffle 30 guides product 130 into the range of the second baffle 40 through tilting guidance. The second baffle 40 utilizes the forward momentum of product 130 to achieve an automatic 90° turn with the end contact point as the fulcrum, eliminating the need for an additional power source and reducing equipment complexity. The third baffle 50 corrects the offset after turning, ensuring a uniform lateral posture of product 130. The fourth baffle 60 fixes the conveying path, preventing product 130 from shaking before entering the coding position.

[0025] This mechanical collaborative design not only saves on the labor costs of dedicated steering but also perfectly matches the production line speed, eliminating speed fluctuations from manual operation and significantly improving production efficiency. Simultaneously, the stability of the mechanical structure ensures consistent steering angles. Manual steering is prone to angle deviations due to fatigue or operating habits, while the fixed position and guiding accuracy of the baffle guarantee minimal steering angle error for each product, laying the foundation for accurate subsequent coding. Furthermore, the entire system requires no complex electronic control components, relying on the product's own inertia to complete the steering, reducing equipment failure rates and maintenance costs, and making it more suitable for high-load production environments in workshops.

[0026] Furthermore, the first baffle 30, the second baffle 40, the third baffle 50, and the fourth baffle 60 are all adjustable baffles. Each of the adjustable baffles includes an adjustable connecting seat 70, a connecting rod 80, and a baffle body 90. The adjustable connecting seat 70 is connected to one side of the conveyor belt 10, and one end of the connecting rod 80 is movably connected to the adjustable connecting seat 70, while the other end is connected to the baffle body 90.

[0027] This design improves the versatility of the equipment and reduces production changeover costs. In power bank production, the 130 size of the product is often adjusted due to changes in capacity and appearance design (such as from thin to thick, from narrow to wide). If the baffle is not adjustable, a custom baffle must be made for each size, which not only increases spare parts costs but also requires downtime for replacement, affecting production continuity. However, the adjustable baffle, through the cooperation of the adjustable connecting seat 70 and the connecting rod 80, can quickly adjust the tilt angle of the baffle (such as the guide angle of the first baffle 30) and the length of its extension into the conveyor belt 10 (such as the abutment position of the second baffle 40), adapting to different sizes of the 130 product without replacing any parts.

[0028] Furthermore, the adjustable structure enhances the ease of equipment debugging. Before starting the production line, the position of the connecting rod 80 on the adjustable connecting seat 70 can be finely adjusted to accurately calibrate the effective range of each baffle, ensuring that the steering and guiding effects meet expectations. If product 130 becomes stuck or its posture deviates during production, it can also be quickly resolved through fine adjustments, reducing downtime for debugging.

[0029] Furthermore, the adjustable connecting seat 70 includes a fixed part 71 and a movable part 72. The fixed part 71 is fixedly connected to one side of the conveyor belt 10, and the movable part 72 is pivotally connected to the fixed part 71 via a pivot. The movable part 72 has a locking mechanism 100, and one end of the connecting rod 80 is movably connected to the movable part 72.

[0030] In this design, the fixed part 71 is rigidly connected to the conveyor belt 10 to ensure the stability of the base position; the movable part 72 achieves multi-angle rotation via a pivot to meet different guiding requirements; the locking mechanism 100 firmly fixes the movable part 72, the fixed part 71, and the connecting rod 80 after adjustment, preventing loosening due to impact from the product 130 or equipment vibration. Furthermore, the pivot connection makes angle adjustment more precise. Compared to adjustment without a pivot, the pivot provides a stable center of rotation, allowing operators to quickly adjust the baffles to preset angles (such as the tilt angle of the first baffle 30 and the convergence angle of the third baffle 50) using scale markings or visual alignment, reducing adjustment errors.

[0031] Furthermore, the locking mechanism 100 includes a knob 101 and a fastening screw 102. The movable part 72 has a threaded hole. The knob 101 is connected to one end of the fastening screw 102, and the other end of the fastening screw 102 is movably inserted through the threaded hole and abuts against the connecting rod 80.

[0032] When debugging or changing product specification 130, operators do not need to use tools such as wrenches. They can control the movement of the fastening screw 102 simply by rotating knob 101: rotating knob 101 clockwise moves the screw forward and presses against connecting rod 80 to lock it in place; rotating it counterclockwise loosens it, facilitating quick adjustment of the baffle position or angle. This tool-free operation significantly reduces adjustment time. For example, when switching from product specification A to product specification B, the locking adjustment of all baffles can be completed in just a few minutes, avoiding the cumbersome process of traditional multi-bolt structures and improving production changeover efficiency.

[0033] Meanwhile, the screw-holding locking method provides a more secure fixation. Compared to snap-on locking (which is prone to loosening due to vibration), the fastening screw 102 generates a continuous and uniform holding force through threaded transmission. The locking force can be controlled as needed via the knob 101. For the second and third baffles 50, which frequently come into contact with the product 130, the locking force can be appropriately increased to prevent loosening due to long-term impact; for the fourth baffle 60, which is adjusted less frequently, the force can be appropriately reduced to facilitate subsequent fine-tuning. This controllable locking force ensures the positional stability of the baffles under various working conditions and reduces production failures caused by locking failure.

[0034] Furthermore, a soft rubber layer 110 is provided on the surface of the baffle body 90.

[0035] The addition of the soft adhesive layer 110 improves the quality stability of product 130 and reduces the risk of cosmetic damage. In traditional designs without the soft adhesive layer 110, the hard contact between product 130 and the baffle can lead to multiple problems: for example, when the first baffle 30 guides product 130, the hard plastic baffle may leave friction scratches on the side of product 130; when the second baffle 40 abuts against the front edge of product 130 for turning, the metal baffle may leave dents; when the third baffle 50 corrects the posture, the compression between product 130 and the baffle may cause edge wear. Although these damages do not affect the function of product 130, they reduce the appearance grade of product 130 and increase rework or scrap costs.

[0036] The soft rubber layer 110 (such as silicone or rubber) has a certain degree of elasticity, which can buffer the impact force during contact through deformation: when the product 130 contacts the baffle, the soft rubber layer 110 absorbs some kinetic energy, reducing the pressure and friction on the surface of the product 130, thus preventing scratches and indentations from the source. At the same time, the friction of the soft rubber layer 110 is moderate, neither too slippery causing the product 130 to deviate from its intended direction, nor too rough to hinder the movement of the product 130 (for example, when the third baffle 50 is correcting, the soft rubber layer 110 can assist the product 130 in smoothly adjusting its posture and avoiding jamming). For the power bank product 130, which emphasizes appearance, this design directly improves the finished product qualification rate, reduces customer complaints caused by appearance issues, and indirectly enhances the market competitiveness of the product 130.

[0037] Furthermore, the end abutment of the second baffle 40 has an arc-shaped guide surface 41.

[0038] At the moment of turning, the front edge of product 130 contacts the end of the second baffle 40. If it is a right-angle structure, the contact point is only a line, and stress concentration can easily cause product 130 to be obstructed and stop. Especially when product 130 is moving at a high speed, it may deviate from the path due to sudden force, or even tip over. However, the arc-shaped guide surface 41 changes the contact point from a line to a surface, guiding product 130 to rotate gradually through the curved surface: when the edge of product 130 slides along the arc surface, the direction of force changes naturally with the curved surface, making the rotation process smoother and avoiding sudden jamming.

[0039] Meanwhile, the curved design reduces damage to the edges of product 130. Right-angled ends may scratch the front edge of product 130 upon contact (such as the plastic corner of a power bank), resulting in burrs or chips; while the smooth transition of the curved surface reduces friction, preventing significant damage to the edges of product 130 even with prolonged contact. Furthermore, the smooth turning process reduces the dwell time of product 130 in the turning area, making the production line rhythm more stable and preventing subsequent product 130s from piling up due to turning difficulties in a single product 130, indirectly improving overall production efficiency.

[0040] Furthermore, the space between the third baffle 50 and the second baffle 40 gradually decreases to form a converging channel, the minimum width of which matches the width of the product 130 laterally.

[0041] Without a convergence channel, product 130 may experience various offsets after turning: for example, some products 130 may deviate laterally to the left, some to the right, or not be parallel to the edge of the conveyor belt 10, causing the inkjet printer 20 to be unable to align with a uniform position (such as the preset inkjet area at the bottom of a power bank), resulting in problems such as skewed printing or printing outside the edge, increasing the rework rate. In this solution, the space between the third baffle 50 and the second baffle 40 gradually decreases along the conveying direction, forming a funnel-shaped convergence channel: the channel entrance width is slightly larger than the maximum possible lateral offset range of product 130, and the exit width is consistent with the standard lateral width of product 130. When the turned product 130 enters the channel, if there is an offset, it will contact the third baffle 50 or the second baffle 40, and slide along the baffle surface under the push of the conveyor belt 10, gradually being squeezed into the standard position. This passive correction requires no additional power; it only utilizes the movement of product 130 itself to achieve uniform posture, ensuring that all products 130 have completely consistent lateral position and angle when entering the area of ​​the fourth baffle 60.

[0042] For the coding process, a uniform posture means that the coding machine 20 can be preset with fixed parameters (such as coding position and height), without the need for frequent adjustments due to product 130 offset, which greatly improves coding accuracy and stability and reduces defective products caused by posture deviation.

[0043] Furthermore, a channel parallel to the edge of the conveyor belt 10 is formed between the fourth baffle 60 and the third baffle 50.

[0044] This parallel channel ensures the stability of the product 130's posture before inkjet printing, directly improving inkjet printing accuracy. In traditional designs, if there is no constrained channel from the turning point to the inkjet printing position, the product 130 may slide laterally or rotate due to unevenness of the conveyor belt 10 surface, slight collisions between adjacent products 130, or the influence of airflow in the workshop, causing its posture to shift again when it reaches the inkjet printing position.

[0045] The parallel channel formed by the fourth baffle 60 and the third baffle 50 has a width that strictly matches the standard lateral width of the product 130, and the channel direction is parallel to the edge of the conveyor belt 10. After the product 130 enters the channel, its two sides are in contact with the fourth baffle 60 and the third baffle 50 respectively (or maintain a slight gap), preventing lateral sliding or rotation, and allowing it to move linearly along the channel direction. This rigid constraint ensures that when the product 130 reaches the coding position, the relative position of its bottom coding area and the inkjet printer 20 is completely fixed. The inkjet printer 20 does not need to adjust its parameters due to fluctuations in the position of the product 130, enabling precise point-to-point coding.

[0046] Furthermore, a stable transport path reduces the waiting time of the inkjet printer 20. If the product 130's posture is unstable, the inkjet printer 20 may need to be frequently checked and adjusted, reducing inkjet printing efficiency; while the parallel channel ensures that the product 130 arrives at a uniform speed and posture, allowing the inkjet printer 20 to work at a fixed rhythm, perfectly matching the production line speed and further improving production efficiency.

[0047] Furthermore, the inkjet printer 20 is equipped with a sensor 120, which is used to detect the arrival position and status of the product 130 and trigger the inkjet printer 20 to perform precise inkjet printing.

[0048] In traditional contactless inkjet printing, common problems include: when the spacing between products 130 is uneven, timed printing may cause some products 130 to be missed (when the spacing is too large) or the printing may overlap (when the spacing is too small); manual triggering is prone to printing position deviation due to reaction delay. In this solution, the sensor 120 (such as a photoelectric sensor or vision sensor) can detect in real time whether the product 130 has reached the printing position and whether the posture meets the requirements: when the product 130 accurately enters the printing area and the lateral posture is correct, the sensor 120 immediately sends a signal to trigger the inkjet printer 20 to work; if the product 130 has not arrived or the posture is abnormal (such as not turning due to malfunction), it will not be triggered, thus avoiding invalid printing.

[0049] Furthermore, the conveyor belt 10 has a length of 2000mm and a width of 400mm.

[0050] The conveyor belt 10 of this size is designed to balance production efficiency and space utilization. Its 2000mm length ensures sufficient travel distance for the product 130 from the starting point to the coding position, facilitating guiding, turning, and corrective actions by the baffles, and providing ample sensing and coding time for the inkjet printer 20 to ensure coding quality. The 400mm width accommodates the conveying needs of various product specifications 130, avoiding both excessive width leading to wasted space and excessive narrowness restricting product size variations, thus enhancing the equipment's versatility and flexibility. Furthermore, this size design considers the actual layout of the production site, facilitating integration with upstream and downstream equipment to form a smooth assembly line operation.

[0051] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
