Detailed Implementation

[0019] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0020] like Figures 1 to 7 As shown, this embodiment of the invention provides a cabinet enclosure clamping and flipping structure system, including a main frame 1, a clamping arm slide rail 2, a sliding support frame 3, a clamping arm 4, a flipping mechanism assembly 5, a clamping platform 6, an anti-slip protection block 7, a hydraulic cylinder assembly 8, a ball screw 9, a foot reinforcement plate 10, and a ball screw fixing seat 11.

[0021] In practical implementation, the main frame 1 is vertically mounted and fixed to the ground or a mobile platform. The main frame 1 has a U-shaped groove, and the bottom of the sliding support frame 3 has pulleys 33. The pulleys 33 are placed within the U-shaped groove to form a clearance sliding fit, thus constraining the sliding support frame 3 to move only vertically. A ball screw 9 is vertically mounted on the main frame 1 and connected to it via a ball screw mounting bracket 11. The ball screw 9 has a self-locking threaded pair, allowing the sliding support frame 3 to remain at any height when power is off, preventing the cabinet from falling. A first rotary motor (not shown) is located at the top of the ball screw 9, used to drive the ball screw 9 to rotate forward and backward.

[0022] The sliding support frame 3 is equipped with a ball screw sleeve 34 that is threaded with the ball screw 9 and a pulley 33 that slides and guides the main frame 1. It moves up and down vertically under the drive of the first rotary motor. The sliding support frame 3 integrates a clamping mechanism and a tilting mechanism. The bottom of the sliding support frame 3 is equipped with a hydraulic cylinder fixing support 31, a fixing support surface 32, a limiting pulley 33, and a ball screw sleeve 34.

[0023] The arm-clamping slide rail 2 is fixed on the fixed support surface 32 of the sliding support frame 3. The cross-section of the arm-clamping slide rail 2 is inverted T-shaped. The bottom of the arm-clamping 4 is provided with a sliding support foot 41 that matches the inverted T-shaped cross-section, so that the arm-clamping 4 can slide linearly in the horizontal direction. One end of the hydraulic cylinder assembly 8 is hinged to the sliding support frame 3 through the hydraulic cylinder fixing support 31, and the other end is hinged to the arm-clamping 4 through the hydraulic cylinder push rod fixing support 42, forming a symmetrical four-bar linkage structure to ensure that the two arms-clamping 4 open and close synchronously and the clamping center remains constant.

[0024] The flipping mechanism assembly 5 is mounted on one of the clamping arms 4 and includes a second rotary motor and a reducer. The clamping platform 6 is rotatably supported between the two clamping arms 4 via flanges. The rotation axis of the clamping platform 6 coincides with the center of gravity axis of the cabinet, ensuring the cabinet is in torque balance during the flipping process. Driven by the second rotary motor, the clamping platform 6 rotates relative to the clamping arms 4 within a range of 0° to 90°. A brake (not shown) is installed between the clamping platform 6 and the clamping arms 4. The brake is a normally closed electromagnetic brake that automatically clamps the output shaft of the flipping mechanism when power is off, preventing the cabinet from rotating due to gravity.

[0025] Anti-slip protective blocks 7 are fixed to the surface of the clamping platform 6 that contacts the cabinet to prevent slippage and scratches. Anti-slip protective blocks 7 are made of flexible materials such as rubber to ensure a good fit with the cabinet surface.

[0026] The system also includes an angle sensor (not shown), a pressure sensor (not shown), and a controller (not shown). The angle sensor is used to detect the flipping angle of the clamping platform 6 in real time; the pressure sensor is used to detect the clamping force of the hydraulic cylinder assembly 8 in real time; the controller is connected to the first rotary motor, the second rotary motor, the hydraulic cylinder assembly 8, the angle sensor, and the pressure sensor, and is used to automatically complete the entire process of lifting, clamping, flipping, and placing according to set parameters, and automatically stop the machine in case of abnormality. The controller has multiple preset cabinet size formulas, and automatically adjusts the clamping opening, clamping force, and flipping angle by calling different formulas to adapt to different cabinet sizes.

[0027] The structure of the present invention will be further described in detail below with reference to specific implementation methods.

[0028] like Figure 4 As shown, in the initial state, the cabinet body 11 to be flipped is fixed on the turnover pallet 13 and is delivered by a forklift or AGV to the cabinet body clamping and flipping structure system of the present invention. The positioning system ensures that the clamping center of the cabinet body 11 to be flipped coincides with the clamping center of the cabinet body clamping and flipping structure system.

[0029] First, the servo motor drives the ball screw 9, which moves the sliding support frame 3 downward to the clamping position of the cabinet 11 to be flipped, so that the clamping arm 4 is aligned with the clamping point of the cabinet 11. The hydraulic cylinder assembly 8 controls the two clamping arms 4 to open synchronously, ensuring that the clamping center remains unchanged.

[0030] Next, the hydraulic cylinder assembly 8 controls the two clamping arms 4 to close synchronously. The clamping force is preset, and the sensor confirms that the clamping force has reached the set value, ensuring that the cabinet body 11 to be flipped can be safely and stably clamped. The servo motor continues to drive the ball screw 9, and the clamping arms 4 slightly lift the cabinet body 11 to be flipped, separating it from the turnover pallet 13.

[0031] Subsequently, as Figure 6 As shown, the servo motor drives the ball screw 9, causing the entire clamping and tilting assembly to move upwards to the tilting position of the cabinet housing 11 to be tilted, as... Figure 5 As shown. The flipping mechanism component 5 is activated, and the second rotary motor drives the clamping platform 6 to slowly and smoothly flip to 90 degrees through the reducer. The sensor monitors the flipping angle in real time. When the preset position is reached, the motor stops running, and the flipping action is completed.

[0032] like Figure 7 As shown, the servo motor drives the ball screw 9, moving the entire clamping and tilting assembly and the cabinet body 11 to be tilted downwards to the placement surface of the target state turnover tray 14. The hydraulic cylinder assembly 8 controls the two gripping arms 4 to open synchronously, placing the cabinet body 11 to be tilted onto the target state turnover tray 14. The servo motor drives the ball screw 9, moving the entire clamping and tilting assembly upwards, causing the gripping arms 4 to move away from the cabinet body 11, completing the tilting operation of the cabinet body 11.

[0033] The cabinet clamping and flipping structure system of the present invention can also be deployed according to actual needs. The foot reinforcement plate 10 can be fixed to the ground, production line, or AGV trolley, realizing two deployment methods: fixed workstation or mobile workstation. When fixed to an AGV trolley, the present invention can become an intelligent handling robot, realizing fully automatic handling and flipping.

[0034] The cabinet clamping and flipping structure system of the present invention has advantages such as compact structure, stable operation, strong adaptability, simple operation and maintenance, and high safety. The system can realize efficient conversion of the cabinet between horizontal and vertical states, and is suitable for various industrial scenarios such as assembly, welding, and testing. It can effectively reduce manual labor intensity and improve production efficiency.
