Description

Technical Field

[0001] This application relates to the field of adhesive impregnation technology for complex-shaped workpieces, and in particular to an automatic adhesive impregnation line and its usage method. Background Technology

[0002] Complex-shaped workpieces cannot be fully coated with glue by brushing; they require dipping in glue. Dipping, whether manual or mechanical, requires preheating the workpiece before dipping and drying it afterward, necessitating multiple handling operations, making the process complex.

[0003] Existing dipping machines can only perform dipping; they require additional transport, drying, and handling components, resulting in low production efficiency, inconsistent coating quality, significant health risks to operators from volatile adhesives, and large footprint. While some existing automated dipping lines have achieved partial automation, they often have fixed conveyor cycles and low workstation utilization, making them unsuitable for complex processes with closely linked multi-stage operations.

[0004] Therefore, we propose an automatic glue-impregnation line and its usage method. Summary of the Invention

[0005] In response to the shortcomings of the existing production technology, the applicant provides an automatic dipping line and its usage method. The chain moves three stations at a time, which is perfectly synchronized with the rhythm of loading and unloading, dipping, and drying. The entire line is linked in a cycle. From preheating, dipping in base glue, drying base glue, dipping in top glue, drying top glue to unloading, there is no waiting time. Batch after batch moves very smoothly, and the mass production efficiency is far higher than that of manual or semi-automatic production lines.

The loading area has three stations, with the middle station being the loading station. The drying area has thirteen stations. The dipping area has three stations: the first station along the chain's conveying direction is for dipping the base adhesive, and the third station is for dipping the top adhesive. The unloading area has three stations, with the middle station being the unloading station. The chain uses a stepping drive, moving three stations at a time. Each station has a corresponding positioning support; the loading fixture with the workpieces attached is placed on the positioning support at the loading station. The drying tunnel assembly, located in the drying zone of the conveyor line, is used to preheat the workpiece and dry the base adhesive and top adhesive; The dipping workstation is located on one side of the dipping area of ​​the conveyor line. The dipping workstation includes a frame, on which are a base adhesive dipping assembly and a top adhesive dipping assembly with identical structures. The base adhesive dipping assembly is located at the base adhesive dipping station, and the top adhesive dipping assembly is located at the top adhesive dipping station. The base adhesive dipping assembly includes a moving mechanism, a gripper assembly, a glue tank assembly, and a glue supply assembly. The glue supply assembly supplies glue to the glue tank assembly. The gripper assembly is located on the moving mechanism and is used to clamp the loading fixture. The moving mechanism drives the gripper assembly to move in order to dip the workpiece in glue.

[0007] The drying tunnel assembly includes a drying chamber and a heating fan. The drying chamber is located on the drying area of ​​the conveyor line and has an inlet and an outlet. The heating fan is located on the top of the drying chamber and delivers hot air into the drying chamber.

[0011] The glue supply assembly includes a glue storage tank, which is connected to a glue bucket via a pump and pipeline, and is used to supply glue liquid to the glue bucket.

[0012] The dip-in workstation is equipped with detection components at both the bottom dip-in station and the top dip-in station to detect whether there are feeding fixtures on the positioning supports at the bottom dip-in station and the top dip-in station.

When the drive mechanism is working, the output shaft of the drive mechanism drives the sprocket to rotate, and the sprocket drives the chain to move.

[0015] This application also discloses a method for using an automatic impregnation line, which includes the following steps: Several loading fixtures with the finished workpieces are placed next to the loading station; The glue supply unit supplies glue to the glue tank; the heating fan is started. Adjust the chain drive mechanism so that the chain moves three steps at a time, and the interval between two adjacent steps is greater than the application time of the base adhesive and top adhesive. Then the chain drive mechanism starts to work. Workers place the loading fixture with the hung workpieces onto the positioning support from the loading station, and the loading continues as the chain moves forward. When the detection component of the base adhesive impregnation station detects that there is a feeding fixture on the positioning support of the base adhesive impregnation station, the base adhesive impregnation component moves the feeding fixture into the glue bucket for base adhesive impregnation. After the base adhesive is impregnated, the base adhesive impregnation component moves the feeding fixture back to the positioning support of the base adhesive impregnation station. When the detection component of the topcoat dipping station detects that there is a feeding fixture on the positioning support of the topcoat dipping station, the topcoat dipping component moves the feeding fixture into the glue bucket to dip the topcoat. After the topcoat is dipped, the topcoat dipping component moves the feeding fixture back to the positioning support of the topcoat dipping station.

[0042] Specifically, the driving mechanism can be a stepper motor, or other structures capable of stepper driving.

[0043] The drying tunnel assembly 200 is installed on the drying zone 1022 of the conveyor line 100 and is used to preheat the workpiece and dry the base adhesive and top adhesive.

The drying chamber 201 is set on the drying area 1022 of the conveyor line 100, and the drying chamber 201 is provided with an inlet and an outlet, which are respectively used by the chain 102 to drive the positioning support 103 into the drying chamber 201 and by the chain 102 to drive the positioning support 103 to move out of the drying chamber 201.

[0044] The heating fan 202 is installed on the top of the drying chamber 201. The heating fan 202 delivers hot air into the drying chamber 201, thereby preheating the workpiece and drying the base adhesive and top adhesive.

[0045] The dipping station 300 is located on one side of the dipping area 1023 of the conveyor line 100. The dipping station 300 includes a frame 301, on which a base adhesive dipping assembly and a top adhesive dipping assembly with the same structure are mounted. The base adhesive dipping assembly includes a moving mechanism 302, a gripper assembly 303, a glue tank assembly 304, and a glue supply assembly 305. Glue is supplied to the glue tank assembly 304 through the glue supply assembly 305. The gripper assembly 303 is mounted on the moving mechanism 302 and is used to clamp the loading fixture 400. The moving mechanism 302 drives the gripper assembly 303 to move in order to dip the workpiece in glue.

[0046] The moving mechanism 302 includes an X-axis moving mechanism 3021, a Z-axis moving mechanism 3022, and an R-axis rotating mechanism 3023. The Z-axis moving mechanism 3022 is mounted on the X-axis moving mechanism 3021 and moves through the X-axis moving mechanism 3021. The R-axis rotating mechanism 3023 is mounted on the Z-axis moving mechanism 3022 and moves through the Z-axis moving mechanism 3022. The gripper assembly 303 is mounted on the R-axis rotating mechanism 3023 and rotates through the R-axis rotating mechanism 3023.

[0048] During operation, the X-axis moving mechanism 3021 and the Z-axis moving mechanism 3022 drive the gripper assembly 303 to move, and then the gripper assembly 303 clamps the loading fixture 400 on the positioning support 103. Then, the X-axis moving mechanism 3021 and the Z-axis moving mechanism 3022 drive the gripper assembly 303 and the loading fixture 400 to move into the glue tank assembly 304 for glue impregnation. After impregnation, the Z-axis moving mechanism 3022 drives the gripper assembly 303 and the loading fixture 400 to move above the glue surface, and the R-axis rotating mechanism 3023 drives the gripper assembly 303 and the loading fixture 400 to rotate, removing excess glue from the workpiece.

[0054] In other embodiments, the impregnation workstation 300 is equipped with detection components at both the bottom impregnation station and the top impregnation station to detect whether there is a feeding fixture 400 on the positioning support 103 at the bottom impregnation station and the top impregnation station.

[0055] Specifically, the detection component can be a sensor or other structure capable of performing detection functions.

[0062] Workers only need to load materials at the loading station and unload materials at the unloading station. They don't need to worry about the complicated processes of impregnation and drying. No professional training is required. The operation is simple and error-free, avoiding various operational mistakes made by manual impregnation.

[0063] Chain 102 moves three stations at a time, perfectly matching the rhythm of loading and unloading, dipping, and drying. The entire line operates in a cyclical manner, with no idle time for the workpieces from preheating, dipping in base glue, drying in base glue, dipping in top glue, drying in top glue, to unloading. Batch after batch moves very smoothly, and the efficiency of mass production is far higher than that of manual or semi-automatic production lines.

[0064] The three-axis movement and rotary glue-spinning design allows for precise control of immersion depth and duration. After immersion, it can rotate and spin to remove excess glue, resulting in a uniform glue layer thickness and completely eliminating problems such as sagging, glue accumulation, and exposed substrate. The 3041 glue tank allows for stirring, preventing glue sedimentation and ensuring a continuous supply. The base and top coats are applied separately, with preheating of the workpiece before immersion and dedicated drying after immersion, maximizing glue adhesion and preventing common problems such as delamination and incomplete drying.

[0065] Equipped with a tooling detection function, the glue dipping process will only start when there is a workpiece at the workstation, preventing the waste of glue and electricity by running empty. The entire process of conveying, drying and glue dipping is fully automated, eliminating the need for constant human supervision. It also reduces personnel contact with the glue, making it safer and completely avoiding quality fluctuations caused by human hand tremors or inattention.

[0066] The ring chain 102, combined with the structure of the track trolley, ensures stable movement and accurate positioning of the tooling support, preventing wobbling and damage to the workpiece. The stepper drive ensures precise stopping positions at each station, and the dipped grippers achieve zero deviation in material handling and unloading. It is also less prone to failure during long-term continuous production and is simple and convenient for daily maintenance.

[0067] A method for using an automated glue-dipping line includes the following steps: Multiple 400-piece loading fixtures are placed next to the loading station; The glue supply component 305 supplies glue to the glue tank 3041; the heating fan 202 is started. Adjust the drive mechanism of chain 102 so that chain 102 moves three steps at a time, and the interval between two adjacent steps is greater than the application time of base adhesive and top adhesive. Then the drive mechanism of chain 102 starts to work. Workers place the loading fixture 400, after the workpieces are hung, onto the positioning support 103 from the loading station, and the loading continues as the chain 102 advances. When the detection component of the base adhesive impregnation station detects that there is a feeding fixture 400 on the positioning support 103 of the base adhesive impregnation station, the base adhesive impregnation component moves the feeding fixture 400 into the glue tank 3041 for base adhesive impregnation. After the base adhesive is impregnated, the base adhesive impregnation component moves the feeding fixture 400 back onto the positioning support 103 of the base adhesive impregnation station. When the detection component of the topcoat dipping station detects that there is a feeding fixture 400 on the positioning support 103 of the topcoat dipping station, the topcoat dipping component moves the feeding fixture 400 into the glue tank 3041 to dip the topcoat. After the topcoat is dipped, the topcoat dipping component moves the feeding fixture 400 back onto the positioning support 103 of the topcoat dipping station. When the unloading station has a loading fixture 400 on the positioning support 103, the worker moves the loading fixture 400 off the positioning support 103.

[0068] In the actual work process, workers only need to load materials from the loading station and unload materials from the unloading station. The operation is simple and errors are not easy to occur.

[0069] When a loading fixture 400 is placed on the positioning support 103 of the loading station, it moves forward with the chain 102. The loading fixture 400 passes through the drying chamber 201 for the first time, where the workpiece on the loading fixture 400 is preheated. When the loading fixture 400 moves to the base adhesive impregnation station, the base adhesive impregnation assembly moves the loading fixture 400 into the adhesive tank 3041 for base adhesive impregnation. After impregnation, the base adhesive impregnation assembly moves the loading fixture 400 back to the positioning support 103 of the base adhesive impregnation station. Then, the loading fixture 400 moves forward with the chain 102 for the second time through the drying chamber 201. 01. The base adhesive of the workpiece is dried in the drying chamber 201. The feeding fixture 400 moves to the top adhesive dipping station with the stepping of the chain 102. The top adhesive dipping assembly moves the feeding fixture 400 into the glue tank 3041 for top adhesive dipping. After dipping, the top adhesive dipping assembly moves the feeding fixture 400 onto the positioning support 103 of the top adhesive dipping station. Then, the feeding fixture 400 passes through the drying chamber 201 for the third time with the stepping of the chain 102 to dry the top adhesive of the workpiece.
