Description

Technical Field

[0001] This invention belongs to the technical field of game controller assembly equipment, and particularly relates to a game controller joystick cap assembly device and method. Background Technology

[0002] With the rapid development of the gaming industry, the market demand for game controllers continues to grow, and users are placing higher demands on the feel, durability, and aesthetics of game controllers. To improve operational comfort and product quality, more and more game controllers are using joystick caps made of metal materials (such as aluminum alloy and stainless steel). After polishing and anodizing, their surfaces are smooth, wear-resistant, and have a superior feel.

[0003] However, there are significant technical challenges in assembling metal rocker caps: due to the smooth surface and low coefficient of friction of metal, traditional clamping mechanisms in assembly devices struggle to achieve stable clamping. Specifically, when using traditional rigid grippers, the small contact area with the metal rocker cap results in insufficient friction, easily leading to slippage and detachment, causing assembly interruptions and reduced production efficiency. To improve clamping stability, some devices increase clamping force, but the high hardness and brittleness of the metal rocker cap surface mean that excessive clamping force can cause surface scratches, deformation, and even damage to the internal mounting structure, affecting product yield. Existing adaptive clamping mechanisms are mostly designed for plastic materials, increasing friction through flexible materials, but their effectiveness is limited when facing metal surfaces. Furthermore, they lack real-time pressure detection and dynamic adjustment mechanisms, making it impossible to precisely control the clamping force based on the dimensional tolerances and surface condition of the rocker cap, thus affecting assembly results. Summary of the Invention

[0004] The purpose of this invention is to provide a device and method for assembling joystick caps for game controllers, aiming to solve the technical problems in the prior art where the clamping mechanism of traditional assembly devices is difficult to achieve stable clamping and cannot accurately control the clamping force according to the size tolerance and surface condition of the joystick cap, thus affecting the assembly effect.

[0005] To achieve the above objectives, the present invention provides a game controller joystick cap assembly device, comprising an electrical control box, an indexing conveyor, and a six-axis assembly robot. The electrical control box is fixed to the side of the indexing conveyor and electrically connected to both the indexing conveyor and the six-axis assembly robot. The indexing conveyor is used to convey the game controller housing, and the six-axis assembly robot is disposed on one side of the indexing conveyor. The six-axis assembly robot is used to clamp the joystick cap and assemble the joystick cap onto the game controller housing on the indexing conveyor.

[0006] The six-axis assembly robot includes a six-axis assembly manipulator, an assembly gripper, and a current controller. The six-axis assembly manipulator is located on one side of the indexing and conveying device. The assembly gripper is fixed to the six-axis assembly manipulator. The assembly gripper assembles the joystick cap to the game controller housing through the six-axis assembly manipulator. The current controller is located on the side of the six-axis assembly manipulator and is electrically connected to the electrical control box and the assembly gripper.

[0007] As an optional embodiment of the present invention, the assembly gripper includes a gripper housing, a gripper drive assembly, a first gripper arm, and a second gripper arm. The gripper housing is fixed to the six-axis assembly robot, the gripper drive assembly is fixed to the gripper housing, and the first and second gripper arms are sequentially fixed to the gripper drive assembly and movably disposed within the gripper housing. A first adaptive clamping assembly is fixed inside the first gripper arm, and a second adaptive clamping assembly is fixed inside the second gripper arm.

The first flexible clamping layer is fixed to the outside of the first gripper arm, the first pressure sensor is fixed inside the first flexible clamping layer, and the first electromagnet is fixed inside the first gripper arm and disposed on one side of the first pressure sensor. The first pressure sensor and the first electromagnet are both electrically connected to the electrical control box.

The second flexible clamping layer is fixed to the outside of the second gripper arm, the second pressure sensor is fixed inside the second flexible clamping layer, and the second electromagnet is fixed inside the second gripper arm and disposed on one side of the second pressure sensor. Both the second pressure sensor and the second electromagnet are electrically connected to the electrical control box. The first gripper arm and the second gripper arm clamp the rocker cap. The first pressure sensor and the second pressure sensor detect the pressure value. When the pressure value reaches a set value, they transmit a signal to the electrical control box. The electrical control box transmits the signal to the current controller. The current controller controls the current magnitude of the first electromagnet and the second electromagnet, and also controls the magnetic force of the first electromagnet and the second electromagnet.

[0010] As an optional embodiment of the present invention, the gripper drive assembly includes a gripping motor, a transmission gear, a first rack, a first slider, a second rack, a second slider, and a movable slide rail. The gripping motor is fixed to the gripper housing, and the transmission gear is fixed to the gripping motor and meshes with the first rack and the second rack respectively. The first slider is fixed to the first rack and the first gripper arm, and the second slider is fixed to the second rack and the second gripper arm respectively. The first slider and the second slider are slidably connected to the movable slide rail in sequence. The first rack is fixed to the first gripper arm, and the second rack is fixed to the second gripper arm. The movable slide rail is fixed to the gripper housing.

[0011] As an optional embodiment of the present invention, the indexing conveying device includes an indexing drive assembly, an indexing disk, a limiting assembly, and a fixture. The indexing drive assembly is connected to the indexing disk and drives the indexing disk to rotate. The limiting assembly is fixed to the indexing drive assembly and limits the indexing disk. The fixture is fixed to the indexing disk and is used to support the game controller housing. The indexing drive assembly includes an indexing drive motor and an indexing drive shaft. The indexing drive motor is electrically connected to the electrical control box. The indexing drive shaft is fixed to the indexing drive motor and the indexing disk respectively, and drives the indexing disk to rotate through the indexing drive motor. The indexing disk is provided with multiple indexing limiting holes. The fixture is provided with a fixture positioning groove, which is used to limit the game controller housing.

[0012] As an optional embodiment of the present invention, the limiting component includes a limiting cylinder and a limiting rod. The limiting cylinder is fixed to the indexing drive motor and electrically connected to the electrical control box. The limiting rod is fixed to the limiting cylinder and is disposed below the indexing limiting hole. The limiting rod is inserted into the indexing limiting hole through the limiting cylinder and limits the indexing plate.

[0013] As an optional embodiment of the present invention, the fixture is provided in multiple quantities, which are the same as the number of the indexing limiting holes, and the multiple fixtures are evenly fixed to the indexing plate.

[0014] Based on the same inventive concept, this application also provides a method for assembling a game controller joystick cap, including the following steps:

[0015] S1: Equipment initialization, setting the clamping pressure threshold, indexing plate speed and six-axis assembly robot movement speed parameters through the electrical control box, and establishing electrical connections with the indexing conveyor and the six-axis assembly robot respectively;

[0016] S2: Game controller housing positioning. The game controller housing is placed into the fixture positioning slot of the indexing conveyor. The control box sends a drive command to the indexing drive component, which drives the indexing plate to rotate to the assembly station. The limit rod of the limit component is inserted into the indexing limit hole to achieve indexing plate positioning.

[0017] S3: Adaptive clamping of rocker cap. The six-axis assembly robot moves the assembly gripper to the feeding station. The gripper drive assembly drives the first gripper arm and the second gripper arm to move towards each other, so that the first flexible clamping layer of the first adaptive clamping assembly and the second flexible clamping layer of the second adaptive clamping assembly are in contact with the surface of the metal rocker cap.

[0018] S4: Clamping force closed-loop control. The first pressure sensor and the second pressure sensor detect the clamping pressure in real time. When the pressure value reaches the set threshold, a signal is sent to the electrical control box. The electrical control box adjusts the output current of the first electromagnet and the second electromagnet through the current controller to control the magnetic force to maintain a stable clamping state.

[0019] S5: Precision assembly operation. The six-axis assembly robot moves the joystick cap it is holding to the assembly station, aligns it with the joystick mounting post on the game controller shell, and inserts it vertically at a uniform speed to the set depth.

[0020] S6: Gripper reset and cycle. After assembly, the electrical control box controls the gripper drive assembly to drive the first gripper arm and the second gripper arm to open in the opposite direction. The current controller cuts off the power supply to the electromagnet, and the six-axis assembly robot resets to the feeding station. At the same time, the limit assembly unlocks, the indexing plate rotates to the next station, and steps S2-S5 are repeated to achieve continuous assembly.

[0021] The game controller joystick cap assembly device and method provided in this embodiment of the invention have at least one of the following technical effects:

[0022] The game controller joystick cap assembly device and method provided in this application achieve real-time detection and adaptive adjustment of the joystick cap clamping force by setting adaptive clamping components in the first and second gripper arms and combining the synergistic effect of pressure sensors and electromagnets. When the first and second gripper arms clamp the joystick cap, the first and second pressure sensors detect the clamping pressure in real time. When the pressure reaches a set threshold, the control box adjusts the current of the electromagnet through the current controller, thereby controlling the strength of the magnetic force so that the clamping force matches the weight and surface characteristics of the joystick cap. This prevents excessive clamping force from deforming the joystick cap, effectively avoids the joystick cap slipping due to insufficient clamping force, improves assembly stability, and results in better assembly.

Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0050] In one embodiment of the present invention, such as Figures 1-10 As shown, a game controller joystick cap assembly device is provided, including an electrical control box 1, an indexing conveyor 2, and a six-axis assembly robot 3. The electrical control box 1 is fixed to the side of the indexing conveyor 2 and is electrically connected to the indexing conveyor 2 and the six-axis assembly robot 3 respectively. The indexing conveyor 2 is used to transport the game controller housing 4. The six-axis assembly robot 3 is set on one side of the indexing conveyor 2 and is used to clamp the joystick cap 5 and assemble the joystick cap 5 onto the game controller housing 4 on the indexing conveyor 2.

[0051] The six-axis assembly robot 3 includes a six-axis assembly manipulator 31, an assembly gripper 32, and a current controller 33. The six-axis assembly manipulator 31 is located on one side of the indexing conveyor 2. The assembly gripper 32 is fixed to the six-axis assembly manipulator 31. The assembly gripper 32 assembles the joystick cap 5 onto the game controller housing 4 through the six-axis assembly manipulator 31. The current controller 33 is located on the side of the six-axis assembly manipulator 31 and is electrically connected to the electrical control box 1 and the assembly gripper 32, respectively.

[0052] In another embodiment of the present invention, the assembly gripper 32 includes a gripper housing 321, a gripper drive assembly 322, a first gripper arm 323, and a second gripper arm 324. The gripper housing 321 is fixed to the six-axis assembly robot 31, the gripper drive assembly 322 is fixed to the gripper housing 321, and the first gripper arm 323 and the second gripper arm 324 are sequentially fixed to the gripper drive assembly 322 and movably disposed in the gripper housing 321. A first adaptive clamping assembly 325 is fixed inside the first gripper arm 323, and a second adaptive clamping assembly 326 is fixed inside the second gripper arm 324. The first adaptive clamping assembly 325 is electrically connected to the electrical control box 1 and the electrical connection controller, respectively, and the second adaptive clamping assembly 326 is electrically connected to the electrical control box 1 and the electrical connection controller, respectively. The first gripper arm 323 automatically clamps the rocker cap 5 through the first adaptive clamping assembly 325, and the second gripper arm 324 automatically clamps the rocker cap 5 through the second adaptive clamping assembly 326.

[0053] In another embodiment of the present invention, the first adaptive clamping assembly 325 includes a first flexible clamping layer 3251, a first pressure sensor 3232, and a first electromagnet 3253. The first flexible clamping layer 3251 is fixed to the outside of the first gripper arm 323, the first pressure sensor 3232 is fixed inside the first flexible clamping layer 3251, and the first electromagnet 3253 is fixed inside the first gripper arm 323 and disposed on one side of the first pressure sensor 3232. The first pressure sensor 3232 and the first electromagnet 3253 are both electrically connected to the electrical control box 1. As the first gripper arms 323 close towards each other, the first flexible clamping layer 3251 first adheres to the surface of the metal rocker cap 5, increasing friction through anti-slip textures to initially form clamping contact. After adhesion, the clamping force gradually increases, and the built-in first pressure sensor 3232 collects contact pressure data in real time and synchronizes the signal to the electrical control box 1. When the pressure value reaches the set threshold, the electrical control box 1 adjusts the output current through the current controller 33, driving the first electromagnet 3253 to generate a corresponding magnetic force, attracting the metal rocker cap 5, further enhancing clamping stability. During the assembly process, the pressure sensor continuously monitors, and if the pressure fluctuates due to slight displacement of the rocker cap 5, the electrical control box 1 adjusts the electromagnet current in real time to maintain stable clamping force. After assembly, the current controller 33 cuts off the power supply, the electromagnet magnetic force disappears, the gripper arms open, the flexible clamping layer detaches from the rocker cap 5, and the component returns to its initial state.

[0054] In another embodiment of the present invention, the second adaptive clamping assembly 326 includes a second flexible clamping layer 3261, a second pressure sensor 3262, and a second electromagnet 3263. The second flexible clamping layer 3261 is fixed to the outside of the second gripper arm 324, the second pressure sensor 3262 is fixed inside the second flexible clamping layer 3261, and the second electromagnet 3263 is fixed inside the second gripper arm 324 and disposed on one side of the second pressure sensor 3262; the second pressure sensor 3262 and the second electromagnet All 3263 are electrically connected to the electrical control box 1; the first gripper arm 323 and the second gripper arm 324 clamp the rocker cap 5, the first pressure sensor 3232 and the second pressure sensor 3262 detect the pressure value, and when the pressure value reaches the set value, the signal is transmitted to the electrical control box 1, the electrical control box 1 transmits the signal to the current controller 33, the current controller 33 controls the current magnitude of the first electromagnet 3253 and the second electromagnet 3263, and controls the magnetic force of the first electromagnet 3253 and the second electromagnet 3263. As the second gripper arm 324 closes towards the first gripper arm 323, the second flexible clamping layer 3261 of the component first adheres to the surface of the metal rocker cap 5, increasing friction through anti-slip textures to form initial clamping contact. The clamping force gradually increases as the grippers close, and the built-in second pressure sensor 3262 collects contact pressure data in real time and synchronously feeds the signal back to the control box 1. When the pressure value reaches the set threshold, the control box 1 adjusts the output current through the current controller 33, driving the second electromagnet 3263 to generate a corresponding magnetic force, attracting the metal rocker cap 5 and forming a symmetrical clamping with the first adaptive clamping component 325 to avoid slippage. During the assembly process, the pressure sensor continuously monitors the pressure. If the pressure fluctuates due to the displacement of the rocker cap 5, the control box 1 adjusts the electromagnet current in real time to maintain a stable clamping force. After assembly, the current controller 33 cuts off the power supply, the electromagnet magnetic force disappears, the gripper arms open, the flexible clamping layer detaches from the rocker cap 5, and the component returns to its initial state.

[0055] In another embodiment of the present invention, the gripper drive assembly 322 includes a gripping motor 3221, a transmission gear 3222, a first rack 3223, a first slider 3224, a second rack 3225, a second slider 3226, and a moving slide rail 3227. The gripping motor 3221 is fixed to the gripper housing 321, and the transmission gear 3222 is fixed to the gripping motor 3221 and meshes with the first rack 3223 and the second rack 3225 respectively. The first slider 3224 is fixed to the first rack 3223 and the first gripper arm 323 respectively, and the second slider 3226 is fixed to the second rack 3225 and the second gripper arm 324 respectively. The first slider 3224 and the second slider 3226 are slidably connected to the moving slide rail 3227 in sequence. The first rack 3223 is fixed to the first gripper arm 323, and the second rack 3225 is fixed to the second gripper arm 324. The moving slide rail 3227 is fixed to the gripper housing 321. The control box 1 sends clamping / releasing commands to the clamping motor 3221, which rotates forward or in reverse according to the command. The motor drives the transmission gear 3222 to rotate, and the transmission gear 3222 meshes with the first rack 3223 and the second rack 3225 to convert the rotational motion into linear motion. The first rack 3223 drives the fixed first slider 3224 to slide along the moving slide rail 3227, thereby driving the first gripper arm 323 to close in opposite directions (clamping) or open in opposite directions (releasing). At the same time, the second rack 3225 drives the fixed second slider 3226 to slide synchronously along the same moving slide rail 3227, driving the second gripper arm 324 to work in coordination with the first gripper arm 323. When clamping, the pressure sensor detects that the pressure has reached the set threshold, or when releasing, it receives a reset command from the control box 1, the motor stops running, and the gripper maintains its current state (stable clamping or fully open).

[0056] In another embodiment of the present invention, the indexing conveying device 2 includes an indexing drive assembly 21, an indexing disk 22, a limiting assembly 23, and a fixture 24. The indexing drive assembly 21 is connected to the indexing disk 22 and drives the indexing disk 22 to rotate. The limiting assembly 23 is fixed to the indexing drive assembly 21 and limits the indexing disk 22. The fixture 24 is fixed to the indexing disk 22 and is used to support the game controller housing 4. The indexing drive assembly 21 includes an indexing drive motor 211 and an indexing drive shaft 212. The indexing drive motor 211 is electrically connected to the electrical control box 1. The indexing drive shaft 212 is fixed to the indexing drive motor 211 and the indexing disk 22, and drives the indexing disk 22 to rotate through the indexing drive motor 211. The indexing disk 22 is provided with a plurality of indexing limiting holes 221. The fixture 24 is provided with a fixture positioning groove 241, which is used to limit the game controller housing 4. The electrical control box 1 sends a rotation command to the indexing drive motor 211 (servo motor). The motor starts according to the command and outputs torque. The motor drives the indexing drive shaft 212 to rotate through the coupling, which in turn drives the indexing plate 22 fixed thereto to rotate synchronously. The motor drives the indexing plate 22 to rotate at a set speed (e.g., 10 r / min). When the fixture 24 reaches the assembly station, the electrical control box 1 receives a position feedback signal and commands the motor to stop. After the motor stops, the indexing plate 22 is fixed by inserting the limit rod 232 of the limit component 23 into the indexing limit hole 221. After the assembly is completed, the electrical control box 1 sends a command again, and the motor restarts to drive the indexing plate 22 to rotate to the next station, thus completing the conveying operation in a cycle.

[0057] In another embodiment of the present invention, the limiting component 23 includes a limiting cylinder 231 and a limiting rod 232. The limiting cylinder 231 is fixed to the indexing drive motor 211 and electrically connected to the electrical control box 1. The limiting rod 232 is fixed to the limiting cylinder 231 and is disposed below the indexing limiting hole 221. The limiting rod 232 is inserted into the indexing limiting hole 221 through the limiting cylinder 231 and limits the indexing plate 22. The indexing drive motor 211 drives the indexing plate 22 to rotate. When the fixture 24 reaches the assembly station, the control box 1 receives the position signal and commands the motor to stop. The control box 1 sends a command to the limit cylinder 231, which drives the limit rod 232 to extend upward and insert into the corresponding indexing limit hole 221 of the indexing plate 22, thereby mechanically locking the indexing plate 22 and preventing displacement during assembly. During the assembly operation, the limit cylinder 231 remains extended, and the limit rod 232 is tightly engaged with the indexing limit hole 221 to maintain the positioning accuracy of the indexing plate 22. After assembly, the control box 1 sends an unlocking command, and the limit cylinder 231 drives the limit rod 232 to retract, disengage from the indexing limit hole 221, and release the constraint on the indexing plate 22 so that the indexing plate 22 can rotate to the next station and complete the positioning operation in a cycle.

[0058] As an optional embodiment of the present invention, multiple fixtures 24 are provided, with the same number as the indexing and limiting holes 221. The multiple fixtures 24 are evenly fixed on the indexing plate 22. The multiple fixtures 24 correspond one-to-one with the indexing and limiting holes 221, and can simultaneously support multiple game controller shells 4. With the rotation of the indexing plate 22, the parallel flow of "loading-assembly-unloading" is realized, improving production efficiency.

[0059] Based on the same inventive concept, this application also provides a method for assembling a game controller joystick cap 5, including the following steps:

[0060] S1: Equipment initialization. Set the clamping pressure threshold, indexing plate 22 rotation speed and six-axis assembly robot 31 movement speed parameters through the electrical control box 1. The electrical control box 1 establishes electrical connections with the indexing conveyor 2 and the six-axis assembly robot 3 respectively.

[0061] S2: Positioning of game controller housing 4: Place the game controller housing 4 into the fixture positioning slot 241 of the indexing conveyor 2. The control box 1 sends a drive command to the indexing drive component 21, which drives the indexing plate 22 to rotate to the assembly station. The limiting rod 232 of the limiting component 23 is inserted into the indexing limiting hole 221 to achieve positioning of the indexing plate 22.

[0062] S3: The rocker cap 5 is adaptively clamped. The six-axis assembly robot 31 drives the assembly gripper 32 to move to the feeding station. The gripper drive assembly 322 drives the first gripper arm 323 and the second gripper arm 324 to move towards each other, so that the first flexible clamping layer 3251 of the first adaptive clamping assembly 325 and the second flexible clamping layer 3261 of the second adaptive clamping assembly 326 are in contact with the surface of the metal rocker cap 5.

[0063] S4: Clamping force closed-loop control. The first pressure sensor 3232 and the second pressure sensor 3262 detect the clamping pressure in real time. When the pressure value reaches the set threshold, a signal is sent to the electrical control box 1. The electrical control box 1 adjusts the output current of the first electromagnet 3253 and the second electromagnet 3263 through the current controller 33 to control the magnetic force to maintain a stable clamping state.

[0064] S5: Precision assembly operation. The six-axis assembly robot 31 moves the held joystick cap 5 to the assembly station, aligns it with the joystick mounting post of the game controller shell 4, and inserts it vertically at a uniform speed to the set depth.

[0065] S6: Gripper reset and cycle. After assembly, the electrical control box 1 controls the gripper drive assembly 322 to drive the first gripper arm 323 and the second gripper arm 324 to open in the opposite direction. The current controller 33 cuts off the power supply to the electromagnet, and the six-axis assembly robot 31 resets to the feeding station.

[0066] The game controller joystick cap 5 assembly device and method provided in this application, by setting an adaptive clamping component in the first gripper arm 323 and the second gripper arm 324, combined with the synergistic effect of pressure sensors and electromagnets, realizes real-time detection and adaptive adjustment of the clamping force of the joystick cap 5; when the first gripper arm 323 and the second gripper arm 324 clamp the joystick cap 5, the first pressure sensor 3232 and the second pressure sensor 3262 detect the clamping pressure in real time. When the pressure reaches the set threshold, the electrical control box 1 adjusts the current of the electromagnet through the current controller 33, thereby controlling the strength of the magnetic force, so that the clamping force matches the weight and surface characteristics of the joystick cap 5, preventing the joystick cap 5 from deforming due to excessive clamping force, effectively avoiding the joystick cap 5 from slipping due to insufficient clamping force, improving assembly stability, and achieving better assembly results.
