[0040] The working principle of this utility model:

[0041] The utility model replaces manpower with machinery, replaces manual handling with self-designed fixtures and programming; for large-volume parts grabbing, a combined adsorption tool is used to enhance the adsorption force of the fixture; for precise grabbing, the grabbing process is autonomously monitored and tracked by sensors; for fast and accurate positioning, stable and reliable fixation, and efficient grabbing and releasing, the grabbing fixture structure is universal and adjustable; due to the variety of large air conditioner models, the grabbing fixture can adapt to chassis of different sizes and shapes, so a modular design concept is adopted to adapt to different chassis specifications through replaceable components. The distance sensor can accurately adjust the position of the clamping point, thereby ensuring compatibility and flexibility with chassis of different sizes.

[0042] Implementation case 1:

[0043] like Figure 1-3 A modular large air-conditioning sheet metal chassis grabbing fixture is shown, including a grabbing fixture, the grabbing fixture includes an electromagnet 6 and a suction cup 1, the suction cup 1 is connected to a suction cup mounting rod 5, the suction cup mounting rod 5 is connected to the electromagnet 6, and the chassis 7 is connected to a distance sensor 3.

[0044] The number of the grabbing clamps is four groups, and an anti-slip pad is provided at the end of the grabbing clamp. The suction cup 1 is connected to the connecting rod 2, and the connecting rod 2 connects the two ends of the suction cup mounting rod 5. The connecting rod 2 is fixedly connected to the suction cup mounting rod 5 by bolts, and the suction cup mounting rod 5 is fixedly connected to the chassis 7 by bolts. The distance sensor 3 adopts an infrared distance sensor, and the distance sensor 3 sends instructions to the manipulator 8 through electrical signals. When the grabbing of the manipulator 8 is abnormal, an alarm is triggered and the work is suspended. The chassis 7 is provided with a flange hole 9 and a sensor hole, and the flange hole 9 is connected to the manipulator 8, and the sensor hole is connected to the distance sensor 3. The sensor 3 is fixedly connected, and the working area of ​​the manipulator 8 includes a processing station 11, a finished product station 12 and a semi-finished product station 13. The suction cup mounting rod 5 is connected to the upper and lower sides of the chassis 7. The suction cup 1 is made of rubber. The upper end of the suction cup 1 is connected to the exhaust pipe 14. The suction cup 1 is adsorbed on the chassis 7. The suction cup mounting rod 5 is provided with an adjustable groove 15. The number of the electromagnets 6 is two, and the electromagnets 6 are connected to the left and right sides of the chassis 7. The side of the suction cup mounting rod 5 is fixedly connected to the push cylinder 4. The push cylinder 4 is made of high-strength alloy material and is provided with a piston rod.

[0045] In this embodiment, the device only needs to place the semi-finished parts in the grabbing area of ​​the semi-finished product station. When the equipment is started or the previous part is processed, the robot 8 carries the self-designed fixture to grab the next part to be processed at the semi-finished product station 13, and moves it to the processing station 11 and releases the part. After the part is processed by three-dimensional laser cutting, the robot 8 moves the fixture to the top of the part, grabs the part again, moves it to the finished product station 12, releases the part, and repeats the operation.

[0046] The modular adsorption design is adopted. The gripping fixture design combines multiple electromagnets 6 and multiple suction cups 1 into a high adsorption force fixture to achieve the absorption of large-volume and heavy-weight parts. At the same time, the modular form is adopted, and the number of suction cups can be increased or decreased according to the weight and volume of the parts, so as to adjust the adsorption force of the fixture and increase the wide applicability of the fixture.

[0047] The suction position is flexibly adjusted. The surface of large chassis parts is uneven, and the fixed position of the suction cup may cause empty suction. By adding a connecting rod 2, the suction position of the suction cup 1 can be flexibly adjusted to adapt to different chassis 7 structures, effectively improving the flexibility of the fixture.

[0048] With the function of grasping in place detection, the fixture design reserves an infrared distance sensor to monitor the grasping process of the parts. The distance sensor 3 sends an action trigger instruction to the manipulator 8. The manipulator 8 can move only after the fixture grasps the parts normally. If the grasping of the parts is abnormal, the device triggers an alarm, and the manipulator 8 pauses and waits for the operator to check and deal with the abnormality before starting the operation.

[0049] The material discharge device is designed, and the side of the gripping fixture is designed with a reserved push cylinder 4 to enable the auxiliary fixture to place the parts normally in the designated working area. When the fixture absorbs and transfers the parts to the workstation, it releases the parts and pushes the parts through the push cylinder 4 to ensure that the parts are completely out of the fixture, providing safety protection for the next action of the manipulator 8.

[0050] Implementation case 2:

[0051] In this embodiment, Figure 1-3 A modular large-scale air-conditioning sheet metal chassis grasping fixture is shown, and the technical means are consistent with the chassis grasping fixture of implementation case one.

[0052] In order to further improve work efficiency, this embodiment is equipped with a quick access and release mechanism for the fixture. This mechanism allows operators to complete the installation and removal of the fixture in a short time, greatly shortening the production cycle. At the same time, the mechanism also has high reliability, ensuring stable performance and reducing failure rate during repeated use. The fixture structure must ensure that the safety of personnel is not threatened at all times. We have added multiple safety protection measures to the design, including emergency stop buttons, protective covers, etc., to prevent accidents.

[0053] In order to further improve the assembly efficiency, we also optimized the working rhythm of the push cylinder 4. By adjusting the speed of the cylinder's air intake and exhaust, the entire clamp grabbing and releasing process is shortened, which significantly shortens the entire assembly cycle. This improvement is of great significance to improving the throughput of the production line. Considering the characteristics of long-term continuous operation of the production line, self-diagnosis and fault warning functions are added to the design. When the push cylinder 4 is abnormal, the system will immediately sound an alarm and automatically shut down, avoiding potential safety risks and reducing the maintenance cost of the equipment.

[0054] The main functions of this utility model:

[0055] The present invention mainly realizes the grasping of large air-conditioning chassis parts by independently designing and manufacturing modular suction cup clamps, combining robot operations, and using machinery instead of manpower. The clamp design is innovatively designed using a modular combination method, which is composed of an electromagnet and a suction cup to enhance the clamp's adsorption force. Each suction cup is relatively independent of the electromagnet, and the clamp's adsorption force can be controlled by increasing or decreasing the number of suction cups in combination with the size of the grasped part, thereby improving the applicability of the clamp. At the same time, the clamp is equipped with a grasping state monitoring sensor and a part detachment device to achieve the purpose of state detection of the grasping process of the large chassis and normal release of the parts. A manipulator and a modular large chassis suction clamp independently designed and manufactured are used to work together to solve the high-intensity labor of employees and reduce the safety risks of employees' operations. The present invention meets the requirements for grasping a variety of large chassis parts, adopts a modular combination design, improves the flexibility of the clamp, and has good promotion prospects.
