Description

Technical Field

[0001] This application relates to the field of automated production lines, and more specifically to a production line for dip coating of parts. Background Technology

[0002] In industrial manufacturing, especially in mass production, automated production lines are widely used to reduce labor intensity, improve operational efficiency, and enhance workplace safety. For the dipping process in parts surface treatment, traditional methods rely primarily on manual operation for loading, weighing, dipping, and warehousing. Current technologies typically use roller conveyors as the basic transport equipment, combined with manual or semi-automatic mechanical assistance to achieve material flow. While some production lines have introduced weighing units and simple handling devices, the overall process still requires significant manual intervention, especially in environments with toxic and volatile paints, where operators are exposed to harmful gases for extended periods, posing serious health and safety hazards. Furthermore, manual operation makes it difficult to ensure consistent loading before each dipping, affecting product quality stability.

[0003] However, existing dipping coating systems generally suffer from discontinuous processes, ineffective human-machine separation, and low levels of automation, resulting in limited production efficiency and an inability to achieve fully automated operation from empty pallet loading to post-dipping warehousing. In particular, the lack of integrated design in areas such as automatic pallet stacking and splitting, precise material feeding and online weighing, automated dipping handling, and intelligent warehouse scheduling hinders the deepening application of intelligent manufacturing in this process.

[0027] See Figure 1 This utility model provides a production line for dip coating of parts, including a conveying device, a pallet handling module, a feeding and weighing module, a handling and dip coating module, a storage module and a control module; The conveying device includes a first roller conveyor line 1 and a second roller conveyor line 10 connected in sequence. The first roller conveyor line 1 is divided into a first section and a second section connected along the material conveying direction. The inlet end of the second roller conveyor line 10 corresponds to the output end of the handling and impregnation module. The pallet handling module includes a palletizing mechanism 3 and a pallet unloading mechanism 4. The palletizing mechanism 3 is set on the conveying path of the first section of the first roller conveyor line 1, and the pallet unloading mechanism 4 is set on the conveying path of the second section of the first roller conveyor line 1. The first section of the first roller conveyor line 1 is equipped with a first stopper on the feeding side of the palletizing mechanism 3 and the end of the second section of the first roller conveyor line 1. The first stopper is electrically connected to the control module. The feeding and weighing module is installed on the conveying device and is electrically connected to the control module; the handling and impregnation module is installed on the conveying device and is electrically connected to the control module. The storage module includes a ground-rail lifting stacker crane 11 and a rack 12. The ground-rail lifting stacker crane 11 is located at the end of the second roller conveyor line 10, and the top of the ground-rail lifting stacker crane 11 is equipped with a conveying module that can connect to the end of the second roller conveyor line 10. The end of the second roller conveyor line 10 is equipped with a third stopper. Each storage location of the rack 12 is equipped with a pallet detection sensor. The ground-rail lifting stacker crane 11, the conveying module, the third stopper, and the pallet detection sensor are all electrically connected to the control unit.

[0028] This embodiment provides a production line for parts impregnation. By integrating a conveying device, a pallet handling module, a feeding and weighing module, a handling and impregnation module, a storage module, and a control module, a complete automated operation system is constructed, realizing fully unmanned operation from empty pallet loading to automatic warehousing after impregnation. This solution effectively solves the problems of high labor intensity, exposure to harmful gas environments, discontinuous processes, and inconsistent cycle times in traditional manual operation modes, improving overall production continuity and safety.

[0029] The conveying system, serving as the material flow channel for the entire system, utilizes two sequentially connected roller conveyor lines 1 and 10 to form a continuous and stable conveying path. Roller conveyor line 1 is divided into two interconnected sections along the material conveying direction, each responsible for pallet buffering and transfer tasks at different functional stages. The first section primarily receives and temporarily stores empty pallets, providing raw material input for subsequent palletizing operations; the second section receives individual pallets separated by the disassembly mechanism 4 and transports them to downstream workstations. The inlet of roller conveyor line 10 corresponds to the output of the handling and coating module, ensuring that pallets can smoothly enter the storage stage after coating is completed.

[0030] The palletizing mechanism 3 is located on the first section of the conveying path of the No. 1 roller conveyor line 1, and is used to automatically stack multiple empty pallets into a preset number, facilitating centralized processing and space utilization. The unpacking mechanism 4 is located on the second section of the conveying path of the No. 1 roller conveyor line 1, and is used to separate the entire stack of pallets layer by layer, releasing only one pallet at a time into the subsequent process. This design avoids congestion or misalignment problems caused by multiple pallets entering at the same time, ensuring the stability of the process cycle. A first stopper is provided on the feeding side of the palletizing mechanism 3 and at the end of the second section of the No. 1 roller conveyor line 1. This stopper is electrically connected to the control module and can be opened and closed under the control module's command, achieving precise control of the pallet flow timing. For example, after the palletizing action is completed, the control module triggers the first stopper to release the next empty pallet; during the unpacking process, after each pallet is released, the subsequent pallet is locked until the current pallet is completely removed. This linkage control mechanism enhances the system's coordination and reliability.

[0031] This application realizes a highly integrated parts impregnation production line. By setting up a continuous conveying channel consisting of a first roller conveyor line 1 and a second roller conveyor line 10, and rationally arranging functional modules such as pallet handling, material feeding and weighing, handling and impregnation, and storage on it, empty pallets can sequentially undergo processes such as pallet stacking, unpalletizing, quantitative loading, automatic impregnation, and intelligent warehousing, all without manual intervention. Therefore, it solves the problems of traditional impregnation processes, such as reliance on manual loading and unloading, inaccurate weighing, poor impregnation consistency, and chaotic storage, achieving the technical effects of reducing operator health risks and improving production efficiency and product quality consistency.

[0032] In a more specific embodiment provided by this utility model, the feeding and weighing module includes a scraper feeder 5, a material dispensing hopper 6, and an online weighing unit 7; The online weighing unit 7 is located downstream of the end of the second section of the first roller conveyor line 1 and is connected to the conveying path of the second section of the first roller conveyor line 1. The material distribution hopper 6 is located directly above the online weighing unit 7. The bottom of the material distribution hopper 6 is provided with an openable and closable leakage gate. The discharge end of the scraper feeder 5 is connected to the inlet of the material distribution hopper 6.

[0033] In this embodiment, the scraper feeder 5 is arranged at an angle, and the height of its discharge end matches the inlet of the material feeding hopper 6, ensuring that the material can fall smoothly into the hopper and avoid spillage. As an optional implementation, the scraper feeder 5 can also be replaced by a vibratory feeder or a screw conveyor, which is especially suitable for feeding small, regular parts in an orderly arrangement.

[0034] In a more specific embodiment of this invention, the online weighing unit 7 is provided with a second stop, which is located at the position where the tray is about to leave the weighing area after the material has been added. It can also be located at its upstream inlet for pre-positioning. The second stop is electrically connected to the control module.

[0035] In a more specific embodiment of this utility model, the bottom of the material dispensing hopper 6 is provided with an openable and closable material leakage gate, and a material shortage sensor is installed inside the material leakage gate; both the material leakage gate and the material shortage sensor are electrically connected to the control module. This technical solution, by setting an openable and closable material leakage gate at the bottom of the material dispensing hopper 6 and configuring a material shortage sensor inside it, combined with the control module to form a closed-loop control system, thereby ensuring the continuity and stability of the parts feeding process.

[0036] In a more specific embodiment of this utility model, the material distribution hopper 6 has a funnel-shaped structure that is wider at the top and narrower at the bottom, which is conducive to the smooth sliding of materials under the action of gravity and reduces bridging or blockage. The material distribution hopper 6 is provided with a mounting beam inside, and the material shortage sensor is fixed to the inner wall of the material distribution hopper 6 through the mounting beam, with the detection end facing the material storage area inside the hopper.

[0037] In a more specific embodiment of this utility model, the transport and impregnation module includes a cantilever truss 8 and an impregnation tank 9; The cantilever truss 8 is spanned between the downstream of the material feeding and weighing module and the inlet end of the No. 2 roller conveyor line 10, and the paint impregnation tank 9 is located below the travel path of the cantilever truss 8.

[0038] In this embodiment, a fully automated material transfer and processing process is achieved by setting up a handling and impregnation module consisting of a cantilever truss 8 and an impregnation tank 9, which completes the transfer and processing from the weighing station to the impregnation process and then to the next level conveyor line. The cantilever truss 8 is equipped with a liftable gripper for grasping the pallet; it reciprocates along a preset track between the downstream of the feeding and weighing module and the entrance end of the second roller conveyor line 10, thereby realizing the transfer of the pallet between different stations.

[0039] In a more specific embodiment of this utility model, the paint impregnation tank 9 is located between the material feeding and weighing module and the second roller conveyor line 10.

[0040] In a more specific embodiment of this utility model, the conveying module of the ground rail lifting stacker 11 includes a roller support and multiple conveying rollers. The conveying rollers are arranged parallel to each other and spaced apart on the roller support, and the top surface of the roller support is flush with the top surface of the end of the second roller conveyor line 10.

[0041] In a more specific embodiment of this utility model, the palletizing mechanism 3 includes a vertical guide frame and a support plate. The vertical guide frames are symmetrically arranged on both sides of the first section of the first roller conveyor line 1, and the support plate is horizontally arranged between the two vertical guide frames and can move up and down along the vertical guide frames to achieve pallet stacking. The support plate is slidably connected to the vertical guide frame through a slider or guide wheel assembly and can reciprocate up and down along the guide frame under the drive of an external drive device. In the initial state, the support plate is in a low position, receiving the first empty pallet from the first roller conveyor line 1; then the support plate gradually rises, continuing to rise a certain height after receiving a new empty pallet each time, so that subsequent pallets are stacked on it layer by layer to form a neat pallet stack. When the number of stacked pallets reaches a preset value, the unpacking mechanism 4 grabs the entire stack of pallets and transfers it to the next workstation, while the support plate returns to its initial position, starting a new round of pallet stacking cycle.

Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
