The loading station 22 is used to place the shell 9, and the positioning groove 221 ensures that each shell 9 placed on the loading station 22 has the same posture when placed manually, which facilitates the subsequent gripping mechanism 3 to clamp the shell 9 and transport it to the detection station 23; the detection station includes the detection station 23, which... 23 has a groove 232 at the center and multiple locking blocks 231. The locking blocks 231 are used to hold the housing 9. The inspection station 23 is used to inspect the roundness of the housing 9. The assembly station includes an assembly station 24. The assembly station 24 is equipped with a turntable 241. The turntable 241 is equipped with a rotating shaft 242. The other end of the rotating shaft 242 is connected to a first rotating motor. The first rotating motor drives the turntable to rotate, thereby rotating the housing 9. The assembly station 24 is used to install foot pads on the housing 9. The pressure holding station includes a pressure holding station 25. The pressure holding station 25 is equipped with the same positioning groove as the loading station 22. The pressure holding station 25 is used to clamp the housing 9 and perform a pressure holding operation on the housing 9. After the pressure holding operation is completed, the housing 9 is conveyed to the unloading unit.
[0038] Furthermore, in order to automatically detect the roundness of the housing 9, a detection unit is provided. The detection unit includes a gripping mechanism 3, a clamping and rotating mechanism 4, and a laser displacement sensor 11. The gripping mechanism 3 is located between the loading station 22 and the detection station 23. The gripping mechanism 3 is provided with a first slide rail 31, which is fixedly mounted on a first support frame. The first support frame is fixedly mounted on the frame 1. A first cylinder 32 is slidably mounted on the first slide rail 31. The output end of the first cylinder 32 is connected to a first gripping component 33. The first gripping component 33 can be a mechanical gripper or a vacuum suction cup. In this embodiment, preferably, multiple vacuum suction cups are provided on the first gripping component 33. Multiple grooves 92 are provided on the housing 9. The vacuum suction cups extend into the grooves 92 and grip the housing 9 by adsorption force. The housing 9 is transported between the loading station 22 and the detection station 23 by the first slide rail 31 and the first cylinder 32.
[0039] A clamping and rotating mechanism 4 is provided at the corresponding inspection station 23. The clamping and rotating mechanism 4 is used to clamp the housing 9 and drive the housing 9 to rotate 360 degrees. A second cylinder 44 is fixedly installed on the clamping and rotating mechanism 4. The second cylinder 44 is fixedly installed on the frame 1. The output end of the second cylinder 44 is connected to a first connecting plate 45. A transmission rod 42 is connected to the end of the first connecting plate 45 away from the second cylinder 44. The other end of the transmission rod 42 is connected to a second gripping component 41. The second gripping component 41 can be a mechanical claw, a vacuum suction cup, or a tray. In this embodiment, a tray is preferably provided at the second gripping component 41. The pallet shape is adapted to the housing 9, clamping and lifting the housing 9 away from the detection station 23, facilitating the subsequent automatic rotation of the housing 9. A rotating wheel 43 is connected to the transmission rod 42 via a belt. The rotating wheel 43 is fixedly mounted on the frame 1 and connected to a motor. The motor drives the rotating wheel 43 to rotate, which is then transmitted to the transmission rod 42 via the belt, enabling the housing 9 to rotate 360 degrees. A laser displacement sensor 11 is installed between the loading station and the detection station, fixedly mounted on the support 21. The roundness of the housing 9 is detected primarily using the triangulation principle of the laser displacement sensor 11. The laser emitter projects a laser beam onto the surface of the object being measured through a lens. The laser beam reflected by the object passes through the receiver lens and is received by the internal imaging element. The projection position of the light spot at different distances on the imaging element is different. Based on the imaging position and optical projection relationship, the distance of the object being measured can be obtained. The imaging element has extremely high position resolution, thus achieving extremely high measurement accuracy. The laser displacement sensor 11 transmits the measured parameters to the first controller. The first controller compares the measured data with preset data to determine whether the roundness of the housing 9 is within the tolerance range. If the measured data is within the tolerance range, an electrical signal is transmitted to the third controller to perform the next process operation. Otherwise, a signal is sent to the alarm device, which stops the operation of other units in the device. The gripping mechanism 3 picks up the housing 9 placed on the detection station 23 and sends it back to the loading station 22 for manual removal.
[0040] Furthermore, to achieve automatic installation of foot pads on the housing 9, an assembly unit is provided. The assembly unit includes: a second support frame, a second controller mounted on the second support frame, a foot pad clamping mechanism 7 mounted on the support frame and electrically connected to the second controller, and a foot pad loading mechanism 6. The foot pad clamping mechanism 7 is located at the bottom of the second support frame and has a rotatable clamping part for gripping the foot pads from the foot pad loading position to the assembly position. The foot pad loading mechanism 6 is located on one side of the loading mechanism 2 and is used to move the foot pads from the foot pad loading position to below the foot pad clamping mechanism 7. The foot pad feeding mechanism 6 has multiple third slide rails 61 arranged in parallel. The third slide rails 61 are fixedly mounted on the frame 1. Multiple fourth slide rails 62 are slidably mounted on the third slide rails 61. Multiple support plates 63 are slidably mounted on the fourth slide rails 62. The support plates 63 are provided with foot pad feeding positions. The foot pad feeding positions include material plates 64. Multiple through holes 641 are arranged in a rectangular pattern on the material plates 64. The material plates 64 are used to place pre-punched foot pad plates 10. The material plates 64 can move in two dimensions in a plane through the cooperation of the third slide rails 61 and the fourth slide rails 62, which facilitates the foot pad clamping mechanism 7 to clamp the foot pads.
[0041] The foot pad clamping mechanism 7 is located between the foot pad feeding mechanism 6 and the assembly station 24. The foot pad clamping mechanism includes: a fifth cylinder 74 fixedly mounted on a second support frame, which is fixedly mounted on the frame 1. The output end of the fifth cylinder 74 is connected to a fourth connecting plate 73. The fourth connecting plate 73 is rotatably connected to a rotating plate 72. Both ends of the rotating plate 72 are provided with clamping portions. Each clamping portion includes a third gripping component 71, which is connected to a second rotating motor. The third gripping component 71 can be a mechanical claw or a vacuum suction cup. In this embodiment, a vacuum suction cup is preferably provided at the third gripping component 71 to suction the foot pad. With the addition of foot pads and the action of the fifth cylinder 74, the foot pads can be quickly detached from the foot pad plate 10. Furthermore, when installing the foot pads into the foot pad holes on the housing 9, it prevents damage to the housing 9 due to downward pressure. Through the cooperation of the foot pad feeding mechanism 6, the foot pad clamping mechanism 7, and the assembly station 24, fast and accurate installation of the foot pads is achieved. By setting two third gripping components 71, one end of the third gripping component 71 installs the foot pad onto the housing 9 at the assembly station 24, while the other end of the third gripping component 71 adsorbs the next foot pad from the foot pad plate 10 at the foot pad feeding mechanism 6. The rotation of the rotating plate 72 enables continuous operation, improving the efficiency of foot pad installation. When the electrical signal indicating the end of the third controller's operation is transmitted to the second controller, the second controller sends an execution signal to the first and second rotating motors. The second controller obtains the electrical signals of the number of rotations of the second rotating motor and the number of executions of the fifth cylinder 74. When the obtained count matches the preset value, the second controller sends an execution signal to the third controller to proceed to the next process.
[0042] Furthermore, in order to achieve automatic clamping of the housing 9 and transfer between various workstations, a gripping unit is provided. The gripping unit includes: a third support frame, a third controller configured on the third support frame, and a housing clamping mechanism 5 configured on the third support frame and electrically connected to the third controller. The housing clamping mechanism 5 is configured on the other side of the loading mechanism 2 away from the foot pad feeding mechanism 6, and is used to clamp and transfer the workpiece to be processed. The housing clamping mechanism 5 includes a second slide rail 54 fixedly mounted on the third support frame. The third support frame is fixedly mounted on the frame 1. A third connecting plate 53 is slidably mounted on the second slide rail 54. A plurality of clamping components 51 are fixedly mounted on the third connecting plate 53. Each clamping component 51 includes a fourth cylinder fixedly mounted on the third connecting plate 53. 513, the output end of the fourth cylinder 513 is connected to the second connecting plate 514, and the other side of the second connecting plate 514 is provided with the third cylinder 512. Clamping plates 511 are provided on both sides of the third cylinder 512. The clamping plates 511 are used to clamp the housing 9. Therefore, the side wall of the clamping plate 511 has an arc-shaped groove on the side away from the third cylinder 512, and an anti-slip layer is provided at the arc-shaped groove to allow the arc-shaped groove to fit against the outer wall of the housing 9 and to prevent the housing 9 from falling off and being damaged during movement. The clamping assembly 51 has a pressure-holding plate 52 at the position corresponding to the pressure-holding station 52. The pressure-holding plate 52 is fixedly set on the third cylinder 512. The pressure-holding plate 52 is used to press and flatten the foot pad during the pressure-holding operation, improving the connection between the foot pad and the housing 9 and preventing the foot pad from loosening. After the pressure-holding operation is completed, the housing 9 is transported to the discharge unit by the housing clamping mechanism 5. A conveying bracket is provided at the discharge unit to allow the housing 9 to enter the next processing step.
