DETAILED DESCRIPTION

[0023] See also Figure 1-Figure 5 A multi-joint industrial robot includes a robot body 100 and a support mechanism 200 arranged at the bottom thereof. The robot body 100 includes a mounting plate 101:

[0024] Furthermore, a welding gun 106 is rotatably connected to the top of the mounting plate 101, and a collection cover 107 for collecting welding slag is provided below the welding gun 106. An elastic hose 112 is fixedly connected to one side of the collection cover 107, and an end of the elastic hose 112 away from the collection cover 107 is fixedly connected to a waste bucket 113. The waste bucket 113 is fixedly arranged on the top of the mounting plate 101, and one side of the waste bucket 113 is fixedly connected to the suction end of an air pump 114, and the bottom of the air pump 114 is fixedly connected to the top of the mounting plate 101.

[0025] The robot body 100 is the main part of the robot, which includes all the motion joints and can achieve multi-dimensional movement. The mounting plate 101 is part of the robot body 100 and is used to fix and support other components. The welding gun 106 is installed on the top of the mounting plate 101. The welding position can be flexibly adjusted by rotating the connection. The collection cover 107 is located below the welding gun 106 and is designed to capture the welding slag generated during the welding process. One end of the elastic hose 112 is fixedly connected to one side of the collection cover 107, and the other end is connected to the waste bucket 113. The use of the elastic hose 112 allows the collection system to expand and contract with the movement of the welding gun 106 to ensure the effective collection of welding slag. The waste bucket 113 is fixed on the top of the mounting plate 101 and is used to store the welding slag transmitted from the collection cover 107 through the elastic hose 112. The air pump 114 is fixed on the top of the mounting plate 101 and is adjacent to the waste bucket 113. The exhaust end of the air pump 114 is connected to the waste bucket 113, and the negative pressure generated helps to suck the welding slag in the collection cover 107 into the waste bucket 113.

[0026] Furthermore, a joint No. 103 is provided above the mounting plate 101, and one side of the joint No. 103 is rotatably connected to the joint No. 2 104, and the end of the joint No. 2 104 away from the joint No. 1 103 is rotatably connected to the joint No. 3 105, and the end of the joint No. 3 105 away from the joint No. 2 104 is rotatably connected to one end of the welding gun 106.

[0027] Joint No. 103 is installed above the mounting plate 101 and is usually the base joint of the robot. It is responsible for the large-scale rotational movement of the robot, enabling the entire arm to rotate in the horizontal plane. Joint No. 2 104 is rotationally connected to one side of joint No. 1 03 and is responsible for up and down swinging, that is, pitching movement. Joint No. 2 104 enables the robot's arm to bend in the vertical direction. Joint No. 3 105 is rotationally connected to the end of joint No. 2 104 away from joint No. 1 03 and continues to extend along the direction of the arm, providing additional bending ability, so that the welding gun 106 can reach more complex positions. Through the combination of three joints, multi-degree-of-freedom movement of the welding gun 106 in space is realized, thereby enhancing the flexibility of the robot.

[0028] Furthermore, a No. 1 electric push rod 102 is fixedly connected to the top of the mounting plate 101 , and a top telescopic end of the No. 1 electric push rod 102 is fixedly connected to the bottom of the No. 1 joint 103 .

[0029] The No. 1 electric push rod 102 is fixedly connected to the top of the mounting plate 101, and the telescopic end at its top is fixedly connected to the bottom of the No. 1 joint 103. The function of the No. 1 electric push rod 102 is to provide telescopic movement in the vertical direction, so that the robot can adapt to working requirements at different heights.

[0030] Furthermore, a No. 2 electric push rod 108 is fixedly connected to the bottom of the collection cover 107, and a rotating plate 109 is fixedly connected to the end of the No. 2 electric push rod 108 away from the collection cover 107. The bottom of the rotating plate 109 is rotatably connected to a fixed seat 110, and the bottom of the fixed seat 110 is fixedly connected to the top of the mounting plate 101.

[0031] By using the No. 2 electric push rod 108 and the rotating plate 109 in conjunction, the collection cover 107 can be made to fit the working position of the welding gun 106 more closely, thereby more effectively collecting welding slag. The rotating plate 109 can rotate around the fixed seat 110, so that the collection cover 107 can follow the different angle changes of the welding gun 106, thereby improving the adaptability and flexibility of the system.

[0032] Furthermore, a third electric push rod 111 is rotatably connected to the top of the mounting plate 101 , and a telescopic end of the third electric push rod 111 is rotatably connected to one side of the rotating plate 109 .

[0033] By adding the No. 3 electric push rod 111, the position of the collection hood 107 can be adjusted more flexibly to ensure that it can always effectively capture welding slag. The rotational connection between the No. 3 electric push rod 111 and the rotating plate 109 allows the collection hood 107 to be adjusted in multiple dimensions to adapt to the requirements of different welding positions.

[0034] Furthermore, a barrel cover 115 is movably connected to the top of the waste barrel 113 , and a handle 116 is fixedly connected to the top of the barrel cover 115 .

[0035] The barrel cover 115 is movably connected to the top of the waste barrel 113 to close the waste barrel 113 to prevent welding slag from overflowing. The design of the barrel cover 115 and the handle 116 makes it easier to open and empty the waste barrel 113 after it is full, which facilitates the final disposal of the waste.

[0036] Furthermore, the support mechanism 200 includes a support base 201 arranged below the mounting plate 101, a fixed plate 202 is fixedly connected inside the support base 201, a ratchet 203 is rotatably connected to the top of the fixed plate 202, a rotating shaft 208 is fixedly connected to the top of the ratchet 203, and the top of the rotating shaft 208 extends to the outside of the support base 201 and is fixedly connected to the bottom of the mounting plate 101.

[0037] Furthermore, a power motor 204 is fixedly connected to the bottom of the inner wall of the support seat 201, and the output shaft of the power motor 204 extends to the top of the fixed plate 202 and is fixedly connected to the bottom of the ratchet 203. A pawl 205 is clamped on one side of the ratchet 203, and the pawl 205 is rotatably set on the top of the fixed plate 202. A fixed block 206 is fixedly connected to the top of the fixed plate 202, and a spring 207 is fixedly connected between the pawl 205 and the fixed block 206.

[0038] When the power motor 204 is started, its output shaft drives the ratchet 203 to rotate. The rotating shaft 208 is fixed to the top of the ratchet 203 and extends to the outside of the support base 201 and is fixedly connected to the bottom of the mounting plate 101. Therefore, the mounting plate 101 and all components above it will rotate with the rotation of the ratchet 203. The pawl 205 is pressed against the tooth surface of the ratchet 203 by the action of the spring 207, allowing the ratchet 203 to rotate in only one direction. When the power motor 204 stops, the pawl 205 will prevent the ratchet 203 from rotating in the opposite direction, thereby keeping the position of the mounting plate 101 unchanged. The support base 201 and the fixing plate 201 are fixed to the mounting plate 101. The design of 02 provides a sturdy support structure, ensuring the smoothness of the rotational movement and the stability of the entire robot. This design not only improves the flexibility and adaptability of the multi-joint industrial robot, but also ensures the reliability and stability of the rotational movement through the one-way locking mechanism. The combination of the ratchet 203 and the pawl 205 driven by the power motor 204 enables the robot to achieve precise rotational movement in the horizontal plane, increases the working range of the robot, and improves the efficiency and quality of the welding operation. The design of the entire support mechanism 200 makes the robot more stable and efficient when performing various complex welding tasks.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
