[0031] The automatic feeding mechanism 1 for the circuit assembly, the automatic feeding mechanism 3 for the sealing gasket, and the automatic feeding mechanism 5 for the top cover are arranged sequentially from left to right on the front side of the mounting plate.

[0032] The automatic circuit assembly feeding mechanism 1 includes two drawer-type circuit assembly hoppers, one on the left and one on the right. The right hopper holds circuit assembly trays filled with materials, while the left hopper retrieves empty circuit assembly trays. In this embodiment, each circuit assembly tray has 5×4 slots and a foolproof corner at the upper left. The hopper is 120mm high and can hold 5 trays at a time, totaling 5×20=100 circuit assembly materials. A tray transport mechanism is provided between the two hoppers to move empty trays from the right hopper to the left hopper.

[0033] The circuit assembly gripping and handling XYZ module 15 is fixed to the rear left end of the mounting plate via the first gantry bracket, extending towards the automatic circuit assembly feeding mechanism 1. It employs a servo motor, guide rail slider, and ball screw structure, allowing the front end of the circuit assembly gripping and handling XYZ module 15 to be positioned in the X-axis (length), Y-axis (width), and Z-axis (height) of the mounting plate. The front end of the circuit assembly gripping and handling XYZ module 15 is connected to the circuit assembly grippers via a rotary cylinder and a gripper cylinder. A circuit assembly material sensor is installed inside the circuit assembly grippers. The circuit assembly grippers are made of SUS304 stainless steel with a silicone pad adhered to the surface.

[0034] The circuit assembly material sensor can detect whether there is material on the circuit assembly gripper; or detect whether there is material in the cavity of the circuit assembly tray.

[0035] The circuit assembly platform translation component 8 is fixedly installed on the rear side of the mounting plate along the X direction, with one end close to the circuit assembly grabbing and loading XYZ module 15, and the other end located in the material picking area of ​​the next process.

[0036] The circuit assembly platform translation component 8 has a linear slide rail on its top and a synchronous pulley and synchronous belt transmission mechanism on its back. The translation platform is slidably mounted on the linear slide rail, and the lower end of the mounting base of the translation platform is fixed to the synchronous belt of the synchronous pulley and synchronous belt transmission mechanism. It can be driven by the synchronous pulley and synchronous belt transmission mechanism to move along the linear slide rail. The circuit assembly platform translation component 8 has an assembly position and a film-peeling position.

[0037] Preferably, the circuit assembly platform translation component 8 is provided with a V-shaped positioning mechanism at the assembly position to ensure the positional accuracy during assembly. The V-shaped positioning mechanism consists of a positioning cylinder and a V-shaped locking block, and a V-shaped notch that cooperates with the V-shaped locking block is provided at the corresponding position on the translation platform.

[0038] A circuit assembly carrier is fixedly installed on the mounting base of the translation platform, which is suitable for carrying circuit assembly materials. A proximity sensor is installed on the inner side of the circuit assembly carrier. Preferably, the proximity sensor is a through-beam photoelectric sensor, which detects electrical components on the circuit board. It can determine whether there is material or whether the material is in a normal posture.

[0039] A circuit assembly carrier notch is provided on one side of the circuit assembly carrier. A circuit assembly side positioning and clamping mechanism is provided on the mounting base of the translation platform facing the circuit assembly carrier notch. The circuit assembly side positioning and clamping mechanism consists of a clamping cylinder and a linear slide rail, which can perform lateral positioning and clamping of the circuit assembly material.

[0040] The lower CCD positioning component 14 of the circuit assembly is fixedly mounted on the mounting plate, located between the automatic circuit assembly feeding mechanism 1 and the circuit assembly stage translation component 8. The lower CCD positioning component 14 consists of a lower CCD, a lens, and a light source, and is mainly used for precise positioning of the circuit assembly. Circuit assembly materials that fail to be photographed during loading are picked up by the circuit assembly grippers and dropped into the NG (Not Good) tray 13; the NG tray 13 has four slots.

[0041] The gasket feeding mechanism 3 includes a drawer-type gasket hopper, which includes a gasket tray support plate that holds only one gasket tray at a time. In this embodiment, the gasket tray has 9×10 slots and a foolproof corner is provided at the upper left corner. The gasket tray support plate is provided with four right-angled locking blocks that match the shape of the four corners of the gasket tray. The gasket tray support plate can move in and out via a drawer slide rail above the gasket hopper. A positioning mechanism is provided below the gasket hopper facing the gasket tray support plate. The positioning mechanism consists of a positioning cylinder and a positioning block. At least one side of the gasket hopper is provided with a gasket tray clamping mechanism, which consists of a clamping cylinder and a clamping block. After replacing the gasket tray, the gasket tray is pushed in, the positioning cylinder pushes the positioning block to extend and clamp the gasket tray support plate, and the clamping cylinder pushes the clamping block to clamp the gasket tray held on the positioning and clamping gasket tray on the gasket tray support plate.

[0042] The lower CCD positioning component 2 is fixedly mounted on the mounting plate, located to the left of the gasket feeding mechanism 3. The lower CCD positioning component 2 consists of a lower CCD, a lens, and a light source. It is primarily used for precise positioning of the gasket during assembly and also functions to position the upper cover. The lower CCD positioning component 2 also includes a gasket ejector box for recycling defective gaskets.

[0043] The automatic lid feeding mechanism 5 includes two drawer-type lid hoppers, one on the left and one on the right. The left lid hopper holds a lid tray filled with lid material, while the right lid hopper retrieves a lid tray empty of lid material. In this embodiment, each lid tray has 6×4 slots and a foolproof corner at the upper left. The lid hoppers can be stacked at least four times. A lid tray transport mechanism is provided between the two lid hoppers to transport the lid tray empty of lid material from the left lid hopper to the lid assembly hopper on the right.

[0044] The upper streamline 7 and the lower return streamline 6 of the carrier constitute a double-layer streamline. The upper streamline 7 is fixedly mounted along the X direction on the mounting plate between the automatic feeding mechanism 5 of the upper cover and the circuit assembly platform translation component 8. The lower return streamline 6 is located below the mounting plate, opposite to the upper streamline 7.

[0045] The vehicle lifting and circulation assembly 4 is installed upstream of the double-layer streamline, passing through the mounting plate. The vehicle lifting and circulation assembly 4 includes a bracket, a lifting cylinder, a lifting limit block, a hydraulic buffer, a linear slide rail, a lifting slide cylinder, and a vehicle circulation streamline. The vehicle circulation streamline can slide along the linear slide rail set on the bracket. The lifting cylinder is used to drive the vehicle circulation streamline to move up and down. The lifting limit block and the hydraulic buffer are set above the bracket to limit and buffer the vehicle circulation streamline.

[0046] A synchronous pulley and synchronous belt conveyor mechanism is respectively arranged opposite to each other on the inner side of the carrier's circulation streamline. The upper cover carrier can be placed on the two synchronous pulley and synchronous belt conveyor mechanisms and conveyed along the synchronous belt of the synchronous pulley and synchronous belt conveyor mechanism. The lifting slide cylinder is located below the upper cover carrier and is used to lift and position the upper cover carrier.

[0047] The carrier circulation line can receive empty carriers conveyed from the lower layer return line 6, lift them to the upper layer flow line, and lift and position the upper cover carrier to facilitate the robot arm to put the cover material into the upper cover carrier.

[0048] The upper flow line 7 and the lower return flow line 6 of the vehicle are each divided into two sections. A synchronous pulley and synchronous belt conveyor mechanism is respectively arranged opposite each other on the inner side of the upper flow line 7 and the lower return flow line 6. The cover vehicle can be placed on the two synchronous pulley and synchronous belt conveyor mechanisms and transported along the synchronous belt of the synchronous pulley and synchronous belt conveyor mechanism. Specifically, an empty cover vehicle can flow back into the lower return flow line 6 from the right side, and then flow to the left along the two sections of the lower return flow line 6. Each section of the lower return flow line 6 can be equipped with a separate empty vehicle return waiting position, which is equipped with a blocking cylinder to prevent empty cover vehicles from passing through.

[0049] The cover carrier, with the material on it, can be transported by the carrier circulation flow line to the upper flow line 7. It then flows to the right along two sections of the upper flow line 7. The first section on the left can have a carrier conveying waiting position equipped with a blocking cylinder to prevent the cover carrier with the material on it from passing through. The second section on the right has a lifting and tearing film position. Above the lifting and tearing film position is an upper pressure plate, and below the upper pressure plate is a polyurethane (PU) elastomer. Below the lifting and tearing film position is a lifting slide cylinder. After the lifting slide cylinder lifts the cover carrier, the upper pressure plate presses the edge of the cover and the cover carrier together, fixing it for easy film tearing. Then, the cover carrier, carrying the torn cover material, proceeds to the next process.

[0050] The robotic arm handling and assembly assembly 11 is fixed to the middle of the mounting plate via a second gantry bracket, spanning above the double-layer streamline. It includes a four-axis robotic arm and a front-end mount, covering the following components: 2. Lower CCD positioning assembly for the sealing gasket; 3. Sealing gasket feeding mechanism; 4. Carrier lifting and circulation assembly; 5. Automatic upper cover feeding mechanism; 6. Lower carrier return line; 7. Upper carrier streamline; 8. Circuit assembly platform translation assembly; 9. Film tearing XYZ module; 10. Air blowing and film polishing assembly; 11. Robotic arm handling and assembly assembly; and 12. Assembly NG material tray. The front-end mount of the robotic arm handling and assembly assembly 11 includes an upper CCD positioning assembly, a laser sensor probe, a sealing gasket contouring suction cup, a vacuum suction cup, a function switching cylinder, and a linear guide rail. The sealing gasket contouring suction cup and vacuum suction cup can move up and down along the linear guide rail and their positions can be switched via the function switching cylinder. The sealing gasket contouring suction cup is made of black polyetheretherketone (PEEK) and has its air channels machined, also serving a compression function. The vacuum suction cup can pick up the top cover and circuit assembly, used for loading the top cover and discarding NG (not yet assembled) circuit assemblies. The upper CCD positioning component consists of an upper CCD, lens, and light source, mainly used for accurately positioning the circuit assembly carrier during gasket assembly, and also compatible with positioning the gasket and top cover during material handling. The laser sensor probe is used for re-inspection after gasket assembly. After gasket assembly, the laser sensor probe detects the height of the gasket to determine if there is any warping. If so, the robot performs a re-pressing action and re-inspects. If it is still not satisfactory, the robot removes it and places it in the assembly NG material tray 12, which has 4 slots. Due to the gasket material, point laser detection is unstable, so line laser detection is required. In this embodiment, the Keyence IX-055 laser sensor probe is selected.

[0051] The film-peeling XYZ module 9 is fixed to the rear right end of the mounting plate via a third gantry bracket, facing the lifting film-peeling position of the upper streamline 7 of the carrier. It employs a servo motor, guide rail slider, and ball screw structure, allowing the front end of the film-peeling XYZ module 9 to be positioned in the length (X), width (Y), and height (Z) directions of the mounting plate. The front end of the film-peeling XYZ module 9 is connected to the display screen film-peeling gripper via a display screen film-peeling gripper cylinder, and also connected to the upper cover inner film film-peeling gripper via an upper cover inner film film-peeling gripper cylinder. Both the display screen film-peeling gripper and the upper cover inner film film-peeling gripper are made of SUS304 stainless steel with a Teflon anti-stick coating.

[0052] The air-blowing and film-polishing assembly 10 is installed behind the lifting and tearing position on the upper streamline 7 of the carrier, passing through the mounting plate. The assembly includes a cover, a cover telescopic cylinder, a film-polishing chamber, a film-polishing box, and an ion generator. The film-polishing chamber is vertically installed through the mounting plate. The cover is operablely positioned above the film-polishing chamber via the cover telescopic cylinder. The ion generator produces ionized air, which is then expelled into the film-polishing chamber through a positive pressure nozzle. The film-polishing box can slide into the area below the film-polishing chamber via a drawer slide rail.

[0053] When peeling the protective film, the screen peeling claw or the inner film peeling claw of the top cover clamps the protective film and extends it into the polishing chamber. The cover moves horizontally to cover the chamber, the claw releases, and at the same time, the positive pressure nozzle blows the protective film off. When the claw is lifted, the cover also acts as a barrier to ensure that the protective film is separated from the claw. The ion generator can eliminate static electricity on the protective film and prevent the protective film from sticking to the claw or cover due to static electricity. The polishing chamber and the cover are both made of SUS304 stainless steel and coated with Teflon for non-stick coating.

[0054] Preferably, the air-blowing and film-polishing assembly 10 further includes an optical fiber sensor, which can detect whether the protective film has been torn off before film polishing and confirm whether the protective film has been polished off after film polishing.

[0055] Preferably, the sealing gasket assembly equipment also includes a frame cover, the top of which is equipped with a tri-color light and a fan filter assembly. The tri-color light is used for alarm indication. The fan filter assembly is used to deliver clean air into the equipment, creating a downward pressure inside the equipment to reduce dust. An observation window is provided at the front of the frame cover, and cooling fans are provided on the sides.

[0056] Preferably, the sealing gasket assembly equipment further includes a control device, which includes a power switch, an emergency stop button, control buttons, a display, a keyboard, a mouse, etc.

[0057] The specific operating procedure of the gasket assembly equipment is as follows:

[0058] I. Circuit assembly loading process:

[0059] The XYZ module 15 for gripping and loading the circuit assembly moves the gripper to the circuit assembly tray. The circuit assembly material sensor detects whether there is circuit assembly material in the cavity. The gripper picks up the material. The rotary cylinder rotates the gripper to adjust the material's posture. The XYZ module 15 moves the gripper to the CCD positioning component 14 under the circuit assembly to take a picture and position the material. If the picture taking and gripping fails, the XYZ module 15 moves the gripper to place the material into the NG tray 13. If the picture taking and positioning of the material is normal, the circuit assembly is placed on the translation platform.

[0060] II. Gasket Assembly and Film Removal Procedure

[0061] The circuit assembly gripper places the circuit assembly into the translation stage; the side positioning clamping mechanism clamps the circuit assembly; the translation stage is moved to the assembly position, and the V-shaped locking block of the V-shaped positioning mechanism positions the translation stage.

[0062] The upper CCD positioning component takes a picture to locate the sealing gasket in the sealing gasket tray; the sealing gasket contour suction cup picks up the sealing gasket; the lower CCD positioning component 2 takes a picture to locate the sealing gasket on the sealing gasket contour suction cup.

[0063] Carrier for CCD positioning component and imaging positioning circuit assembly;

[0064] The robotic arm handles and assembles component 11, assembling the sealing gasket.

[0065] The laser sensor probe detects the height to confirm the sealing gasket assembly effect;

[0066] If the sealing gasket assembly effect is not good, the robot arm handles the assembly component 11 and uses the sealing gasket contour suction cup to re-press the sealing gasket; after the re-pressing is completed, the laser sensor probe checks the assembly effect again.

[0067] If the sealing gasket assembly effect is still poor, the side positioning clamping mechanism is released, and the robot arm transports the assembly component 11 to remove the circuit assembly and place it into the assembly NG material tray 12; the empty translation platform returns to the waiting material placement area.

[0068] If the sealing gasket assembly is satisfactory, the V-shaped locking block descends, and the translation platform moves to the film-tearing position; the display screen film-tearing claw moves to the film-tearing position; the display screen film-tearing claw clamps, and interpolation displacement is used to tear the film.

[0069] The screen tearing gripper moves to the fiber optic sensor of the air-blowing and film-polishing assembly 10 to detect whether the protective film has been torn off, and transmits the information to the next process for re-judgment; the screen tearing gripper moves to the film-polishing assembly 10 to polish the film; after the film is torn off, the translation platform moves to the end of the equipment, and the next process takes away the circuit assembly; the empty translation platform returns to the waiting area for material feeding.

[0070] III. Top Cover Loading and Film Removal Procedure

[0071] The upper CCD positioning component takes a picture and positions the upper cover in the upper cover tray; the robotic arm transports and assembles the upper cover using a vacuum suction cup; the robotic arm transports and assembles the upper cover to the CCD positioning component 2 under the sealing gasket and takes a picture to position the upper cover.

[0072] The vehicle lifting and circulation assembly 4 receives an empty top cover vehicle from the lower return line 6 of the vehicle, lifts and positions it, and then raises it to the position of the upper flow line 7 of the vehicle.

[0073] The robotic arm handles and assembles component 11, placing the top cover onto the top cover carrier. After passing through the waiting position, the top cover carrier moves to the lifting and tearing position. The lifting and positioning of the top cover carrier is achieved, and the upper pressure plate presses and secures the top cover. The inner film tearing gripper moves to the lifting and tearing position. The inner film tearing gripper clamps the film and performs interpolation displacement to tear the film. The inner film tearing gripper moves to the fiber optic sensor of the air-blowing and film-polishing component 10 to detect whether the protective film has been torn off and transmits the information to the next process for verification. The inner film tearing gripper moves to the film-polishing component 10 to perform film polishing. The lifting and lowering mechanism allows the top cover carrier to flow to the next process.

[0074] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
