Abstract
Description
Technical Field
[0001] The present invention relates to a steel cabinet manufacturing device, and more particularly to an intelligent welding device for installing steel cabinet partitions. Background Art
[0002] Compared with wooden cabinets, steel cabinets have better rigidity, impact resistance, fire resistance, and anti-mildew performance. Therefore, steel cabinets are widely used in offices, storage rooms, factory workshops, and the express delivery industry. Steel cabinets are usually made by pressing and splicing multiple steel plates. The steel cabinet partition is located inside the steel cabinet and serves to separate the contents. Currently, the installation of steel cabinet partitions is fully automated at fixed points. During the semi-automatic installation process, mechanical jigs clamp the steel cabinet partitions to the designated positions, and welding is achieved by manual labor or an automatic welding machine during the clamping and positioning process.
[0003] For this method, there are often positioning misalignments when the mechanical jigs clamp the steel cabinet partitions, resulting in the inclination of the welding points or welding failures. The reason is that the clamping and positioning of the mechanical jigs are fixed operations through a pre-set three-dimensional space path. However, each steel cabinet to be installed with partitions will shift during the pre-placement process, or there will be geometric dimension deviations between the intermediate cabinet plate materials produced during the pre-pressing process. Therefore, the pre-set fixed path in the fully automated fixed-point installation process is difficult to meet the requirements of each partition installation. In addition, the partitions often shake during the clamping process, resulting in deviations in the solder joint positions. The above defects will reduce the production yield of steel cabinets in the specific production process, thereby increasing the production cost. Summary of the Invention
[0004] The purpose of the present invention is to overcome the above-mentioned defects existing in the prior art and provide an intelligent welding device for installing steel cabinet partitions.
[0005] The purpose of the present invention can be achieved by the following technical solutions:
[0006] An intelligent welding device for installing steel cabinet partitions, comprising a mobile platform, a column, an I-shaped positioning frame, a telescopic rod a, and a welding arm. The column is vertically connected to the mobile platform. The I-shaped positioning frame is connected to the column through the telescopic rod a. The I-shaped positioning frame includes telescopic rods b on both sides and a cross bar connected to the middle of the telescopic rods b on both sides. One end of the telescopic rod a is movably connected to the column and can move up and down along the column. The other end of the telescopic rod a is connected to the middle of the cross bar. Electromagnets are provided at both ends of the telescopic rod b, and the electromagnets are used to adsorb and position the steel cabinet partitions. One end of the welding arm is movably connected to the column and can move up and down along the column.
[0007] Further, both the telescopic rod b and the cross bar are composed of three pipe fittings connected together. The pipe fitting in the middle is movably nested in the pipe fittings at both ends, and a cylinder is provided on the pipe fitting in the middle. The cylinder is used to push the pipe fittings at both ends to extend.
[0008] Further, the electromagnet is cuboid-shaped, and the cuboid-shaped electromagnet is conducive to surface fitting and adsorption.
[0009] Further, an infrared rangefinder is provided on the electromagnet, and it is used to measure the spatial dimensions inside the steel cabinet.
[0010] Further, slide rails a and b are provided on the column, and one ends of the telescopic rod a and the welding arm are respectively movably connected to slide rail b and slide rail a.
[0011] Further, the telescopic rod a is formed by nesting two pipe fittings. A motor is provided inside the pipe fittings, which can realize relative extension and relative rotation between the two pipe fittings. The relative rotation is used to position the partition placed horizontally or vertically.
[0012] Further, a welding torch is provided at the other end of the welding arm.
[0013] Further, the welding arm is formed by sequentially and movably connecting multiple connecting rods, and a rotating shaft is provided between adjacent two end segments of the connecting rods.
[0014] Further, bending and rotation of the multiple connecting rods are realized through pneumatic control.
[0015] Further, a signal receiver is provided in the connecting rod, a microprocessor is provided in the mobile platform, an ultrasonic thickness gauge and a WiFi signal transmitter are provided in the cross bar. The WiFi signal transmitter is used to send the spatial dimension information inside the steel cabinet measured by the infrared rangefinder and the steel cabinet partition thickness information measured by the ultrasonic thickness gauge to the microprocessor. The microprocessor is used to process the received spatial dimension information inside the steel cabinet and the steel cabinet partition thickness information measured by the ultrasonic thickness gauge into the position information of the welding points to be welded and send it to the signal receiver. The signal receiver plans the rotation mode of the connecting rod according to the position information of the welding points to be welded, and adjusts the height of the welding arm on the column, finally realizing the adjustment of the welding position of the welding torch in three degrees of freedom.
[0016] Compared with the prior art, the present invention has the following advantages:
[0017] First, an I-shaped positioning frame is adopted to be placed inside the cabinet. The upper and lower two electromagnets on the I-shaped positioning frame are used to adsorb the steel cabinet partition, and the two electromagnets on the other side are adsorbed to the fixed steel rail plate members, and the middle cross bar is used for connection, forming a symmetric support structure to stably position the steel cabinet partition;
[0018] 2. The I-shaped positioning frame can obtain the three-dimensional coordinates of the welding site to be welded through the infrared positioning and ultrasonic thickness gauge thereon. The coordinates can be generated in a timely manner according to the placement position of each steel cabinet and different plate sizes, without relying on a pre-set path.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0023] The present invention will be described in detail below with reference to the drawings and specific embodiments.
[0024] Embodiment
[0025] The welding device for installing the steel cabinet partition includes a moving platform 5, a column 2, an I-shaped positioning frame 3, a telescopic rod a 6 and a welding arm 4. Refer to Figure 1 , the column 2 is vertically connected to the moving platform 5, the I-shaped positioning frame 3 is connected to the column 2 through the telescopic rod a 6. The I-shaped positioning frame 3 includes telescopic rods b 32 on both sides and a cross bar 33 connected to the middle of the telescopic rods b 32 on both sides. Refer to Figure 2 , one end of the telescopic rod a 6 is movably connected to the column 2 and can move up and down along the column 2. The other end of the telescopic rod a 6 is connected to the middle of the cross bar 33. Electromagnets 31 are provided at both ends of the telescopic rod b 32. The electromagnets 31 are used to adsorb and position the steel cabinet partition. One end of the welding arm 4 is movably connected to the column 2 and can move up and down along the column 2.
[0026] Both the telescopic rod b32 and the cross bar 33 are composed of three sections of pipe fittings connected together. The pipe fitting located in the middle is movably nested in the pipe fittings at both ends, and a cylinder is provided on the pipe fitting in the middle. The cylinder is used to push the pipe fittings at both ends to extend. The electromagnet 31 is rectangular parallelepiped-shaped. An infrared distance measuring instrument 35 is provided on the electromagnet 31, which is used to measure the spatial dimensions inside the steel cabinet. Slide rails a 21 and slide rails b 22 are provided on the vertical column 2. One ends of the telescopic rod a 6 and the welding arm 4 are movably connected to the slide rails b 22 and the slide rails a 21 respectively. The telescopic rod a 6 is composed of two sections of pipe fittings nested together. A motor is provided inside the pipe fittings, which can achieve relative extension and relative rotation between the two sections of pipe fittings. A welding torch 44 is provided at the other end of the welding arm 4. Refer to Figure 3 , the welding arm 4 is sequentially movably connected by multiple sections of connecting rods 41. A rotating shaft 42 is provided between adjacent two sections of connecting rods 41. Bending and rotation are achieved through pneumatic control among the multiple sections of connecting rods 41. A signal receiver 43 is provided in the connecting rod 41, a microprocessor is provided in the moving platform 5, and an ultrasonic thickness gauge and a WiFi signal transmitter are provided in the cross bar 33.
[0027] During the specific operation process, it is necessary to preset the predetermined traveling trajectory of the moving platform 5 so that it can approach the rail to be installed. After that, the telescopic rod a 6 extends and the electromagnet is powered on. First, use the conveyor belt in the workshop to adsorb the partition to be installed between the two electromagnets. Then, the cross bar 33 extends until the two electromagnets adsorb to the installed plate, and the other two adsorb to the plate to be installed. The telescopic rod a 6 moves up and down to adjust the position so that the upper end or the lower end of the partition to be installed abuts against the installed plate. At this time, the WiFi signal transmitter sends the spatial dimension information inside the steel cabinet measured by the infrared distance measuring instrument 35 and the steel cabinet partition thickness information measured by the ultrasonic thickness gauge to the microprocessor. The microprocessor processes the received spatial dimension information inside the steel cabinet and the steel cabinet partition thickness information measured by the ultrasonic thickness gauge into the position information of the welding points to be welded and sends it to the signal receiver 43. The signal receiver 43 plans the rotation mode of the connecting rod 41 according to the obtained coordinate information, and adjusts the height of the welding arm 4 on the vertical column 2, and finally realizes the adjustment of the welding position of the welding torch 44 in three degrees of freedom.
