Description

Technical Field

[0001] This invention relates to the field of plastic part resist plating processing equipment, specifically an online automatic sprue cutting, oiling, resist plating, and baking integrated machine. Background Technology

[0002] In the production process of plastic-coated iron injection molded parts, the injection-molded workpieces need to undergo multiple post-processing steps, including sprue trimming, localized application of plating resist oil, oil draining, and drying, before entering the next production stage. The purpose of applying plating resist oil is to protect localized areas that do not require plating during subsequent electroplating or electroless plating processes, preventing plating adhesion.

[0003] In traditional processing methods, the aforementioned steps are typically carried out independently and in a decentralized manner, relying on manual transfer of workpieces between steps. This not only results in low production efficiency but also makes it difficult to ensure the accuracy and consistency of oil application location and amount during manual operation. Furthermore, waste generated during the sprue trimming process requires manual cleaning, and the workpieces need to be dried after oiling, requiring transfer between different equipment. The overall processing cycle is long, and labor costs are high, making it difficult to meet the needs of automated mass production. Summary of the Invention

[0004] The purpose of this invention is to provide an online automatic sprue cutting, oiling, resist plating, and baking integrated machine to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an online automatic sprue cutting, oil coating, and baking integrated machine, comprising a frame and a drying chamber. A robotic arm is fixedly connected to the frame. A sprue cutting mechanism, an oil coating and plating mechanism, and an oil draining mechanism are sequentially arranged around the robotic arm on the frame. A circulation line is fixedly connected inside the drying chamber. A tray is fixedly connected to each moving platform of the circulation line. Multiple vacuum adsorption components are fixedly connected to the moving end of the robotic arm. The sprue cutting mechanism includes a first base, a first positioning seat, a first pressing device, and a shearing device. The oil coating and plating mechanism includes a second base, a second positioning seat, a second pressing device, an oil tank, a lifting device, a lifting seat, and an oil reservoir. The oil draining mechanism includes a third base and an oil drain box. The frame is provided with multiple insertion holes. The first base, the second base, and the third base are all fixedly connected to the insertion holes by pins. The oil drain box is fixedly connected to the third base.

[0006] Furthermore, the frame is provided with a waste flow channel at the shearing nozzle mechanism, and the first base is provided with a discharge hole below the shearing device, the discharge hole being arranged corresponding to the waste flow channel.

[0007] Furthermore, the vacuum adsorption assembly includes an adjusting slide and a vacuum nozzle. The adjusting slide is fixedly connected to the output end of the robot arm, and the vacuum nozzle is fixedly connected to the adjusting end of the adjusting slide.

[0008] Furthermore, the first and second clamping devices are specifically rotary clamping cylinders, the lifting device is specifically a sliding cylinder, and the shearing device is specifically a pneumatic scissor.

[0009] Furthermore, both the first positioning seat and the shearing device are fixedly connected to the first base, the first pressing device is fixedly connected to the first positioning seat, and the shearing device is located below the first positioning seat.

[0010] Furthermore, the second positioning seat, oil tank, and lifting device are all fixedly connected to the second base, the second pressing device is fixedly connected to the upper end of the second positioning seat, the oil tank is located below the second positioning seat, the lifting seat is fixedly connected to the moving end of the lifting device, the oil tank is fixedly connected to the lifting seat, and the lifting seat is located inside the oil tank.

[0011] Furthermore, a liquid level sensor is fixedly connected to the oil tank.

[0012] Furthermore, the tray has an upwardly bent edge.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] (1) The four processes of cutting the sprue, applying oil to resist plating, draining oil and drying are integrated into one machine. The workpiece is automatically transferred between each station by a robot, realizing full-process automated continuous processing and improving production efficiency.

[0015] (2) The oil tank is lifted by the lifting device to achieve immersion coating. With the precise positioning of the positioning seat and the clamping device, the position and depth of each coating are consistent, which effectively improves the stability of the resist plating effect and product quality.

[0016] (3) The water-cutting mechanism, the oil-coating and anti-plating mechanism and the oil-draining mechanism are all detachably connected to the frame by pins. The corresponding tooling modules can be quickly changed according to different specifications of workpieces. The changeover operation is simple and quick, and can adapt to the needs of multi-variety and small-batch production.

[0017] (4) Waste is automatically discharged without manual cleaning. The shearing mechanism is equipped with a discharge hole and a waste flow channel. The waste generated by shearing automatically falls into the flow channel and is discharged without manual intervention, which keeps the working environment clean and reduces the labor intensity of operators.

[0018] (5) The oil draining and drying processes are smoothly connected to avoid secondary pollution. After the workpiece is coated with oil, the excess oil is drained through the oil draining box before drying. This not only avoids the pollution and safety hazards caused by a large amount of oil being brought into the drying box, but also ensures the drying efficiency and the quality of the oil film drying.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example:

[0029] Please see Figure 1-7The online automatic sprue cutting, oiling, resist plating, and baking integrated machine shown includes a frame 1 and a drying chamber 2. A robotic arm 3 is fixedly connected to the frame 1. The robotic arm 3 is preferably a four-axis or six-axis industrial robot with multiple degrees of freedom of movement. Around the working range of the robotic arm 3, a sprue cutting mechanism 4, an oiling and resist plating mechanism 5, and an oil draining mechanism 6 are sequentially arranged on the frame 1. The drying chamber 2 is located on one side of the frame 1 and has a circulation line 7 installed inside. Each moving platform of the circulation line 7 is fixedly connected to a tray 701 for carrying the workpiece and circulating it within the drying chamber 2 to complete the drying process. The circulation line 7 can be a double-speed chain conveyor or a stepper conveyor. The workpiece moves along a predetermined path within the drying chamber 2. The drying chamber 2 is equipped with a heating device and a temperature control system to ensure a constant drying temperature.

[0030] The sprue cutting mechanism 4 includes a first base 401, a first positioning seat 402, a first clamping device 403, and a shearing device 404. The first base 401 is fixedly connected to a pin in a hole on the frame 1 for quick positioning and installation. The first positioning seat 402 is fixedly connected above the first base 401, and its shape matches the contour of the workpiece to be processed, used for positioning the workpiece. The shearing device 404 is fixedly connected to the first base 401 and located below the first positioning seat 402. The shearing device 404 is specifically a pneumatic shear, with its blade located directly below the sprue waste connection point of the workpiece. The first clamping device 403 is fixedly connected to the upper end of the first positioning seat 402, specifically a rotary clamping cylinder, whose pressure head can rotate downwards to clamp the workpiece. A discharge hole is opened on the first base 401 below the shearing device 404. A waste flow channel corresponding to the discharge hole is provided on the frame 1, and the sheared waste falls into the waste flow channel through the discharge hole and is discharged.

[0031] The oil-coating resist plating mechanism 5 includes a second base 501, a second positioning seat 502, a second clamping device 503, an oil tank 504, a lifting device 505, a lifting seat 506, and an oil reservoir 507. The second base 501 is also fixedly connected to the insertion hole on the frame 1 via a pin. The second positioning seat 502 is fixedly connected above the second base 501 and is used to position the workpiece. The second clamping device 503 is fixedly connected to the upper end of the second positioning seat 502, specifically a rotary clamping cylinder, and is used to clamp the workpiece. The oil tank 504 is fixedly connected to the second base 501 and located below the second positioning seat 502; the oil tank 504 contains resist plating oil. The lifting device 505 is fixedly connected to the second base 501, specifically a sliding cylinder, whose piston rod extends vertically upwards. The lifting seat 506 is fixedly connected to the end of the piston rod of the lifting device 505, and the oil reservoir 507 is fixedly connected to the lifting seat 506, with an opening at the upper end. The lifting seat 506 is located inside the oil tank 504. Each time the oil reservoir 507 is immersed in the oil tank 504, its chamber is filled with resist plating oil. When the piston rod of the lifting device 505 extends, the lifting seat 506 and the oil reservoir 507 rise together. The upward movement of the oil reservoir 507 immerses the part of the workpiece to be coated into the oil within its chamber. To monitor the oil level in the oil tank 504 in real time, a level sensor is fixedly connected to the tank. When the level falls below a set value, the system issues an alarm to prompt the addition of oil.

[0032] The oil draining mechanism 6 includes a third base 601 and an oil draining box 602. The third base 601 is also fixedly connected to the insertion hole on the frame 1 by a pin. The oil draining box 602 is fixedly connected to the upper end of the third base 601. After the workpiece is placed on the oil draining box 602, the excess oil on the surface drips down and collects in the oil draining box 602 under the action of gravity.

[0033] The moving end of the robotic arm 3 is fixedly connected to multiple vacuum adsorption components for gripping and transferring workpieces. Each vacuum adsorption component includes an adjusting slide 301 and a vacuum nozzle 302. The adjusting slide 301 is fixedly connected to the output end of the robotic arm 3, and the vacuum nozzle 302 is fixedly connected to the adjusting end of the adjusting slide 301. The position of the vacuum nozzle 302 can be finely adjusted by adjusting the slide 301 to adapt to changes in the adsorption surface position of workpieces of different sizes. Multiple vacuum nozzles 302 simultaneously adsorb workpieces, ensuring stable gripping.

[0034] The pallet 701 has upward-bent folds, which are distributed at least on both sides of the pallet 701. When a workpiece is placed on the pallet 701, the folds act as a limit to prevent the workpiece from slipping off the pallet 701 due to vibration or tilting during the movement of the circulating line 7.

[0035] The working principle of this invention is as follows:

[0036] First, the plastic-coated iron injection molded parts, after injection molding, are placed at the predetermined picking position by an external feeding device or manually. The robot arm 3 moves to the picking position, and the vacuum nozzle 302 picks up the workpiece and transfers it to the sprue mechanism 4. After the workpiece is placed in place along the first positioning seat 402, the pressure head of the first clamping device 403 rotates downwards to clamp and fix the workpiece. The shearing device 404 actuates to shear the connection between the finished part of the workpiece and the waste sprue. After shearing, the waste material falls into the waste flow channel through the discharge hole on the first base 401 and is discharged. The pressure head of the first clamping device 403 rotates upwards to reset. The robot arm 3 picks up the workpiece again, removes it from the sprue mechanism 4, and transfers it to the oil coating and resist plating mechanism 5. After the workpiece is placed on the second positioning seat 502, the pressure head of the second clamping device 503 rotates downwards to clamp the workpiece. The piston rod of the lifting device 505 extends, pushing the lifting seat 506 and the oil tank 507 upward, immersing the part of the workpiece that needs to be coated with resist plating into the resist plating oil in the oil tank 507. After soaking for a preset time, the piston rod of the lifting device 505 retracts, the oil tank 507 descends to reset, and the pressure head of the second pressing device 503 rotates upward to reset. The robotic arm 3 picks up the workpiece and transfers it to the oil draining box 602 of the oil draining mechanism 6. The workpiece is left to drain on the oil draining box 602, allowing excess oil to drip off naturally. After draining, the robotic arm 3 transfers the workpiece to the tray 701 in the drying chamber 2. The circulation line 7 drives the tray 701 and the workpiece to circulate within the drying chamber 2. After passing through the heating area in the drying chamber 2, the oil on the surface of the workpiece is dried and solidified, completing all processing steps. Finally, the dried finished product is manually removed from the tray.

[0037] Each mechanism base is fixedly connected to the insertion hole on the frame 1 by a pin. When it is necessary to change to workpieces of different specifications, the sprue mechanism 4, the oil coating and resist plating mechanism 5 and the oil draining mechanism 6 that are compatible with the workpiece specifications can be quickly disassembled and replaced to achieve rapid model change.
