Description

Technical Field

[0001] This utility model relates to the field of material handling and conveying technology, and in particular to an automatic alignment assembly line device after a cleaning machine. Background Technology

[0002] In industrial production fields such as electronic components, precision parts, and food packaging, tunnel cleaning machines are commonly used to clean product surfaces. After cleaning, the products need to be quickly and accurately transferred to subsequent material handling mechanisms (such as robotic arms or conveyor lines) for the next processing step. Therefore, the proper alignment of products at the cleaning machine's outlet is crucial for ensuring the continuous operation of the production line. If products are misaligned or mispositioned, it can lead to subsequent material handling failures, production line shutdowns, and even damage to the products due to the forcibly gripping mechanism.

[0003] In existing technologies, the automation level of product alignment after washing machines is low, relying heavily on manual intervention. Most small and medium-sized enterprises still use manual alignment, requiring workers to be on duty at the discharge port of the washing machine to manually adjust the skewed products to the preset picking position. This method not only incurs labor costs but also takes a long time to align a single product, making it difficult to adapt to the continuous discharge rhythm of the washing machine and easily causing product accumulation. Although some semi-automatic equipment can achieve product conveying, it requires manual assistance to correct deviations. However, the accuracy of manual operation is greatly affected by experience, and the subsequent picking mechanism is prone to problems such as "missing to pick up" or "damaging products" when grabbing. Therefore, an automatic alignment production line equipment after washing machines is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an automatic alignment production line device after the cleaning machine, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The automatic alignment line equipment after the cleaning machine includes a frame, on which a transition conveyor mechanism, a roller conveyor mechanism and a centering mechanism are sequentially arranged along the product conveying direction; The discharge end of the transition conveying mechanism is connected to the feed end of the roller conveying mechanism; The roller conveying mechanism is equipped with a limiting mechanism on its conveying path; The centering mechanism includes two sets of clamping assemblies that extend upward from the roller conveying mechanism in at least part, and the clamping assemblies are connected to the drive assembly. As a further description of the above technical solution: The clamping assembly has clamping members extending upward beyond the roller conveying mechanism, and each clamping assembly has at least two clamping members symmetrically distributed. As a further description of the above technical solution: The surface of the clamping member is covered with a first elastic buffer layer; As a further description of the above technical solution: The clamping assembly is slidably connected to the frame through a guide structure, and the two sets of clamping assemblies run on the same linear motion trajectory, which is perpendicular to the product conveying direction. As a further description of the above technical solution: The drive assembly includes any one of a belt drive motor drive assembly, a lead screw motor drive assembly, a cylinder assembly, a hydraulic cylinder assembly, and a linear motor assembly. As a further description of the above technical solution: Each clamping assembly corresponds to a single driving assembly, and or two sets of clamping assemblies are connected to a lead screw motor drive assembly, wherein the lead screw motor drive assembly is a double-threaded lead screw motor drive assembly; As a further description of the above technical solution: The belt drive motor drive assembly includes three synchronous pulleys and a synchronous belt surrounding the three synchronous pulleys, two of which are rotatably connected to the frame, and the remaining synchronous pulley is connected to the output shaft of the drive motor; As a further description of the above technical solution: The frame is provided with two U-shaped frames, the clamping assembly is slidably connected to the U-shaped frames, the driving assembly is fixed to the inner bottom of the U-shaped frames, and the guide structure is provided at the top of the U-shaped frames; As a further description of the above technical solution: The limiting mechanism includes a cylinder, a limiting component, and a guide component. The cylinder drive end is fixedly connected to the limiting component. Both the cylinder and the guide component are mounted on the frame or side plate. The cylinder drive end passes through the guide component and slides in cooperation with it. As a further description of the above technical solution: The transition conveying mechanism includes a second drive unit and a conveyor belt. The second drive unit is connected to the conveyor belt in a driving connection, and the conveyor belt is mounted on the frame. The roller conveying mechanism includes a first drive unit and a plurality of parallel rollers. The outer surface of the rollers is covered with a second elastic buffer layer and is connected to the first drive unit in a driving connection.

[0006] This utility model has the following beneficial effects: 1. In this utility model, the equipment can complete the entire process of automated operation from product transition conveying, initial correction, precise positioning to synchronous alignment without human intervention. It can accurately match the needs of subsequent material handling mechanisms, which is more efficient than manual correction, while reducing human operation errors and ensuring the continuous and stable operation of the production line.

[0007] 2. In this utility model, a multi-stage product protection structure is formed by the second elastic buffer layer on the outer surface of the roller, the first elastic buffer layer on the outer surface of the clamping member, and the soft material design of the limiting member. This effectively avoids damage and scratches to the product during the conveying, straightening and positioning process after cleaning, and reduces the product scrap rate.

[0008] 3. In this utility model, the drive component supports multiple types of selection, such as belt drive motor, double threaded screw motor, and cylinder. It can be flexibly configured according to the product weight and centering accuracy requirements, and is suitable for product alignment scenarios after cleaning in various industries. At the same time, the adjustable feet or wheels at the bottom of the frame facilitate the adjustment of the equipment's installation position and level, adapting to different workshop environments and cleaning machine models. Furthermore, subsequent maintenance only requires targeted replacement of vulnerable parts such as the timing belt and elastic buffer layer, without the need for overall disassembly and repair, thus shortening maintenance time and reducing enterprise maintenance costs and production line downtime losses.

[0011] 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.

[0012] Reference Figure 1 This utility model provides an embodiment of an automatic alignment production line device after a washing machine, including a frame 1. A transition conveyor mechanism 6, a roller conveyor mechanism 5, and an alignment mechanism 3 are sequentially arranged on the frame 1 along the product conveying direction. The frame 1 is the basic load-bearing structure of the entire device, constructed from high-strength metal profiles (such as square steel or angle steel) welded or bolted together, possessing sufficient rigidity to support the weight of each functional mechanism and the load during operation. Multiple mounting holes and guide rail grooves are pre-drilled on its top along the product conveying direction for fixing the transition conveyor mechanism 6, the roller conveyor mechanism 5, and the alignment mechanism 3. The centering mechanism 3 and side plates 2 and other components ensure that each mechanism maintains a stable relative position during operation, avoiding positioning deviations caused by vibration. At the same time, the bottom of the frame 1 can be equipped with adjustable feet or wheels as needed to adjust the overall level and position of the equipment to adapt to different workshop floor environments. The discharge end of the transition conveying mechanism 6 is connected to the feed end of the roller conveying mechanism 5. The conveying path of the roller conveying mechanism 5 is equipped with a limiting mechanism 4. The centering mechanism 3 includes two sets of clamping components that extend upward from the roller conveying mechanism 5, at least partially, and the clamping components are connected to the drive components.

[0013] Reference Figure 1 , Figure 4 and Figure 5 The clamping assembly has clamping elements 35 extending upwards from the roller conveying mechanism 5, and each clamping assembly has at least two symmetrically distributed clamping elements 35. The clamping elements 35 are strip-shaped or block-shaped structures (made of metal or high-strength plastic). The surface of the clamping elements 35 is covered with a first elastic buffer layer made of soft rubber or foam, which can deform during clamping to increase the contact area with the product and avoid indentation or scratches on the product surface (especially suitable for smooth products after cleaning). The clamping assembly is slidably connected to the frame 1 through the guide structure 36, and the two sets of clamping assemblies run on the same linear motion trajectory, which is perpendicular to the product conveying direction. The guide structure 36 provides precise guidance for the sliding of the clamping assembly and can be composed of a slide rail and a slider. The slider slides in cooperation with the slide rail, and its top is fixedly connected to the bottom of the clamping assembly. It can move freely along the slide rail. Through the constraint of the guide structure 36, the two sets of clamping assemblies can only move along the same horizontal linear line to ensure that there is no offset or jamming during the alignment process. The drive assembly includes any one of the following: belt drive motor drive assembly, lead screw motor drive assembly, cylinder assembly, hydraulic cylinder assembly, and linear motor assembly. A single clamping assembly corresponds to a single drive assembly, or two sets of clamping assemblies are connected to a lead screw motor drive assembly, and this lead screw motor drive assembly is a double-threaded lead screw motor drive assembly. The double-threaded lead screw motor drive assembly consists of a double-threaded lead screw motor and two nut seats. The output shaft of the lead screw motor is a lead screw with oppositely helical threads at both ends. The two nut seats are respectively connected to two sets of clamping assemblies and engage with the lead screw threads. During operation, the lead screw motor rotates, driving the two nut seats to move synchronously in opposite directions through the reverse threads, thereby driving the belt drive motor. The two sets of clamping assemblies move closer or further apart; the belt-driven motor drive assembly includes three synchronous pulleys 33 and a synchronous belt 34 surrounding the three synchronous pulleys 33, two of which are rotatably connected to the frame 1, and the remaining synchronous pulley 33 is connected to the output shaft of the drive motor 32. During operation, the drive motor 32 drives the active synchronous pulley 33 to rotate, and through the transmission of the synchronous belt 34, the clamping assembly slides along the guide structure 36. Its advantages are smooth operation and low noise; the belt-driven motor drive assembly is suitable for lightweight products and scenarios with conventional precision requirements; the double-threaded screw motor drive assembly is suitable for heavy-duty products and scenarios with high precision requirements; the cylinder assembly is suitable for low-cost, fast-response scenarios. The frame 1 is equipped with two U-shaped frames 31. The clamping assembly and the U-shaped frame 31 are slidably connected. The drive assembly is fixed to the inner bottom of the U-shaped frame 31. The guide structure 36 is set on the top of the U-shaped frame 31. The U-shaped frame 31 consists of two symmetrically distributed "U"-shaped metal frames (made of aluminum alloy or steel plate bent into shape) that are fixed to the frame 1 by bolts. The opening direction of the frame 31 faces the product conveying path. The U-shaped frame 31 provides installation and protection for the drive assembly. The guide structure 36 (slide rail + slider) on the top of the frame constrains the two sets of clamping assemblies to slide in a straight line perpendicular to the product conveying direction, ensuring smooth centering without deviation.

[0014] Reference Figure 1 , Figure 2 and Figure 3The transition conveyor mechanism 6 is installed at the input end of the frame 1, adjacent to the discharge port of the tunnel-type washing machine. It serves as a "bridge" structure for products to move from the washing process to the straightening process. The transition conveyor mechanism 6 includes a second drive unit 61 and a conveyor belt 62. The second drive unit 61 is connected to the conveyor belt 62 via a drive mechanism. The conveyor belt 62 is installed on the frame 1. The second drive unit 61 is usually a geared motor, which is connected to the drive roller of the conveyor belt 62 via a coupling or chain drive to provide power for the operation of the conveyor belt 62. Its speed can be adjusted according to the discharge speed of the washing machine to ensure that the products are received smoothly without accumulation. The conveyor belt 62 is made of food-grade or industrial-grade rubber (selected according to product characteristics). The surface can be set with anti-slip texture. During operation, after the second drive unit 61 is started, the conveyor belt 62 runs at a set speed, receiving the products output from the washing machine and conveying them backward. Finally, it is smoothly transferred to the feed end of the roller conveyor mechanism 5, completing the transition transfer of the products. The roller conveying mechanism 5 includes a drive unit 51 and multiple parallel rollers 52. Each roller 52 is covered with a second elastic buffer layer and is connected to the drive unit 51 via a transmission. The drive unit 51 is a variable frequency motor, connected to the rollers 52 via chain drive or synchronous belt drive. The rollers 52 are metal cylinders (such as stainless steel, corrosion resistant), evenly arranged along the width of the frame 1. The distance between adjacent rollers 52 is less than the minimum size of the product (to prevent product drop). Both ends are mounted on the inner side of the side plate 2 via bearing seats, allowing free rotation. The second elastic buffer layer is made of silicone or polyurethane, with a thickness of 2 mm. ~5mm, this layer not only increases the friction with the product and prevents the product from slipping, but also forms a buffer when the product comes into contact with the roller 52, preventing the fragile product from being damaged after cleaning; during operation, the drive device 51 drives the roller 52 to rotate synchronously. After the product enters the surface of the roller 52 from the transition conveying mechanism 6, it moves towards the limiting mechanism 4 as the roller 52 rotates. If the product is skewed, because the rollers 52 are evenly arranged and rotate in the same direction, the difference in friction between the two sides of the product and the roller 52 will push it to gradually adjust its posture, eventually approaching parallel to the conveying direction of the roller 52, thus achieving initial correction; The limiting mechanism 4 includes a cylinder 41, a limiting component 42, and a guide component 43. The limiting mechanism 4 is installed in the middle and rear position of the roller conveying mechanism 5 to accurately control the stopping position of the product on the roller 52. The driving end of the cylinder 41 is fixedly connected to the limiting component 42. Both the cylinder 41 and the guide component 43 are installed on the frame 1 or the side plate 2. The driving end of the cylinder 41 passes through the guide component 43 and slides in cooperation. The cylinder 41 is a standard pneumatic cylinder (such as the SC series) and is fixed to the side of the frame 1 or the side plate 2 by a mounting bracket. The limiting component 42 is a block or plate structure (made of hard plastic or metal with rubber coating) and is fixed to the driving end of the cylinder 41 by bolts. The guide component 43 is a linear bearing, a sliding sleeve, or a long strip plate with sliding holes, which is used to limit the movement trajectory of the piston rod and provide support for it, ensuring that the limiting component 42 is accurately aligned with the product conveying path. During operation, the cylinder 41 is ventilated, and the piston rod drives the limiting member 42 to extend along the guide member 43 onto the product conveying path. The product moves with the roller 52 until it contacts the limiting member 42, at which point it is blocked and stops. At this point, the product is exactly at the correction endpoint of the roller conveying mechanism 5, providing a precise positioning reference for the centering mechanism 3. Working principle: During the product transition conveying stage, the transition conveying mechanism 6 on the frame 1 receives the product output from the outlet of the tunnel cleaning machine. At this time, the drive device 61 of the transition conveying mechanism 6 is started, and the conveyor belt 62 is driven to rotate through the transmission action, so as to smoothly convey the product to the feed end of the connected roller conveying mechanism 5, thus completing the transition of the product from the cleaning process to the straightening process. The drive device 51 of the roller conveying mechanism 5 in the product roller conveying and initial correction stages starts synchronously, driving multiple rollers 52 arranged side by side to rotate. After the product enters the surface of the roller 52, it moves towards the limiting mechanism 4 as the roller 52 rotates. At the same time, due to the uniform arrangement of the rollers 52 and the rotational force, if the product is skewed during the conveying process, it will be gradually adjusted to a posture close to the conveying direction of the roller 52, thus achieving initial correction. In addition, the elastic protective layer covering the outer surface of the roller 52 can prevent the product from being damaged by direct contact with the roller 52. During the product positioning stage, when the product is conveyed to the preset position of the roller conveyor mechanism 5, the cylinder 41 of the limiting mechanism 4 is activated, and its driving end drives the limiting member 42 to extend. During this process, the driving end of the cylinder 41 slides along the guide member 43 to ensure that the limiting member 42 extends smoothly and blocks the product from continuing to be conveyed, so that the product stops accurately at the correction endpoint position of the roller conveyor mechanism 5, providing a positioning reference for subsequent centering actions. After the product is positioned, the centering mechanism 3 is activated. The two U-shaped frames 31 fixed to the frame 1 provide sliding support for the clamping components. The two sets of clamping components are slidably connected to the frame 1 along the guide structure 36 inside the U-shaped frame 31, and the two sets of clamping components move synchronously towards the product along the same trajectory. At the same time, the part of the clamping component that extends on the roller conveying mechanism 5, namely the clamping part 35, moves with the clamping component and gradually approaches the two sides of the product. Then the drive component works. If a belt drive motor drive component is selected, the output shaft of the drive motor 32 drives one of the three synchronous pulleys 33 to rotate. Through the surrounding synchronous belt 34, it drives the other two synchronous pulleys 33 fixed to the frame 1 to rotate synchronously, thereby driving the clamping components to slide along the U-shaped frame 31. If a double threaded screw motor drive component is selected, a single drive component can synchronously drive the two sets of clamping components to slide in opposite directions. Finally, the clamping parts 35 of the two sets of clamping components contact the two sides of the product, centering the product to the preset picking position. The first elastic buffer layer on the surface of the clamping part 35 prevents the product from being squeezed and damaged. After the product is aligned, the drive assembly stops operating, and the two clamping assemblies maintain the alignment state to stabilize the product; the cylinder 41 of the limiting mechanism 4 retracts, driving the limiting component 42 to reset along the guide component 43; after the subsequent material handling mechanism takes away the product, the two clamping assemblies slide back to the initial position along the U-shaped frame 31, preparing for the alignment cycle of the next product.
