Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, in particular to a ground rail type welding robot workstation. Background Art

[0002] Welding robots are widely used in the welding industry due to their high welding quality, high work efficiency and low labor costs. However, due to the limitations of the welding range, a single welding robot has a small working range and cannot complete the welding requirements of workpieces with diverse sizes. Based on this, major companies have begun to develop welding robot workstations to meet the corresponding welding requirements. Ground-track welding robot workstations are also common.

[0003] However, the L-shaped protective plates of the guide rail slides of the existing ground rail welding robot workstations are commonly installed on the outer side. This type of structure can only protect the outer side and the upper surface, so the inner side is not protected properly. The dust and welding slag generated during the welding process will cause the guide rail slide to get stuck or damaged, which requires regular maintenance and replacement, reducing work efficiency and welding quality and increasing costs. In addition, the welding machine, water tank, and electrical control cabinet are placed on the ground outside the workstation. In this case, the above-mentioned electrical accessories and the control lines of the robot need to be routed and connected through the drag chain, which means that the cables are used for a long time and the cost increases accordingly. Too many cables are routed through the drag chain and the drag chain moves with the slide. The cables are prone to tangling and friction damage due to long-term following movement. This not only has a certain impact on the communication effect, but also has high maintenance costs and is inconvenient in the later stage. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that most ground rail type welding robot workstations place welding machines, water tanks, electric control cabinets, etc. on the external ground of the workstation. This placement method requires that the control lines between electrical accessories and the robot need to be routed and connected through a drag chain, which makes the cables longer and increases the cost. In addition, too many cables are routed through the drag chain, and the drag chain moves with the ground rail extension plate, which causes the cables to be easily twisted and damaged by friction after following the movement for a long time, which not only easily affects the communication effect, but also easily leads to high maintenance costs and inconvenience in maintenance. A ground rail type welding robot workstation is proposed.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A ground rail welding robot workstation comprises a tire frame; a walking ground rail is arranged at the top of the outer wall of the tire frame; a slide is slidably connected to the walking ground rail, and a robot body is installed on the slide; a PC end operating table is arranged outside the tire frame; a placement plate is fixedly connected to the top of the outer wall of the tire frame; a slide is slidably connected to the walking ground rail, and a robot body is installed on the slide; L-shaped connecting blocks are installed on both sides of the inner side of the slide, and one side of the slide is fixedly connected to one side of a ground rail extension plate through the L-shaped connecting block; concave side baffles are installed around the slide and the ground rail extension plate. The bottom end of the L-shaped connecting block is fixed on the slide, the slide is mounted on the slide rail, a slide rail mounting plate is mounted on the bottom end of the slide rail, two slide rail mounting plates are symmetrically mounted on the rectangular base, a guide rail protection cover is mounted above the slide rail between the L-shaped connecting block and the slide, the guide rail protection cover is mounted on the slide rail mounting plate through a cover support plate, a rack is mounted on one side of the guide rail protection cover, and a rack guard plate is mounted on the outside of the rack; a welding machine, an electric control cabinet and a water tank are fixedly connected to the top end of the outer wall of the floor rail extension plate; the bottom end of the outer wall of the floor rail extension plate is slidably connected to the outer side wall of the walking floor rail.

[0007] The robot body comprises a mechanical arm, a welding gun and a wire feeder, the mechanical arm is mounted on a ground rail extension plate, a welding gun is mounted at one end of the mechanical arm, a wire feeder is mounted on the mechanical arm, a gun cleaning station bracket is mounted below the mechanical arm, a gun cleaning station is mounted at one end of the gun cleaning station bracket, a power box is mounted on one side of the mechanical arm, a ground rail drive motor is mounted on one side of the power box, an oil pump is mounted at one end of the ground rail drive motor, and wire grooves are mounted around the ground rail drive motor; a welding wire barrel is mounted on one side of the welding machine, a barrel wire fence is arranged on the outer wall of the bottom end of the welding wire barrel, and a wire feeding tube support frame is mounted on one side of the welding wire barrel.

[0008] A camera bracket is also installed above the welding gun on the robotic arm, and the camera bracket includes a mounting plate installed on the robotic arm, an extension plate is installed on the bottom end of the mounting plate, an up and down adjustment plate is installed on the extension plate, an angle adjustment block is movably installed on the up and down adjustment plate, a camera fixing plate is fixedly provided at one end of the angle adjustment block, a 3D camera is installed on one side of the camera fixing plate through a bakelite insulating plate, and the camera fixing plate, the bakelite insulating plate and the 3D camera are fixed by multiple bakelite insulating columns.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. Slide rails and slide tables are arranged on both sides of the rectangular base, and then the L-shaped connecting blocks designed by the present invention are installed on the slide table, and then the concave cover shell support plate is connected to the slide rail fixing block, and then the concave guide rail protection cover shell is connected to the cover shell support plate, so that the inner side and upper surface of the slide table slide rail can be completely protected, and then the slide plate is fixed to the L-shaped connecting block and then the extended mounting plate is fixed to the slide plate, and concave side baffles are installed around the slide plate and the extended mounting plate, so that the outer side of the slide rail and slide table can be protected, and the slide table slide rail is effectively protected, so that dust and welding slag splashing into it can be avoided, so that the maintenance cycle can be increased, and the work efficiency and work quality can be improved.

[0011] 2. Placing the welding machine, water tank, electric control cabinet, etc. on the ground rail extension plate shortens the distance to the robot body. The distance between the two becomes shorter and the connecting cables used also become shorter. This not only greatly reduces the cost but also avoids the risks of twisting and wear and tear caused by too many cables entering the drag chain. Then a wire trough is installed between the two, so that the cables can be better protected, the wiring is also beautiful and maintenance is convenient.

[0012] 3. The present invention also designs a group of electrical quick-plug components in the head cavities on both sides of the rectangular base, and an inlet groove is opened at the lower part of the rectangular base. The quick-plug design facilitates installation, disassembly and maintenance. During actual installation, a groove similar in size to the inlet groove is opened on the factory floor so that the cables enter the rectangular base cavity from the groove and connect with each other. This not only makes the joints beautiful but also well protected. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Embodiment 1:

[0021] See also Figure 1-Figure 4As shown, a ground rail type welding robot workstation includes a tire frame 1; a walking ground rail 2 is provided at the top of the outer wall of the tire frame 1; a slide plate 203 is slidably connected to the walking ground rail 2, and a robot body 3 is installed on the slide plate 203; L-shaped connecting blocks 207 are installed on both sides of the inner part of the slide plate 203, and one side of the slide plate 203 is fixedly connected to one side of the ground rail extension plate 6 through the L-shaped connecting block 207; concave side baffles 202 are installed around the slide plate 203 and the ground rail extension plate 6, and the bottom end of the L-shaped connecting block 207 is fixed to the slide table 2 06, the slide 206 is mounted on the slide rail 205, the bottom of the slide rail 205 is mounted with a slide rail mounting plate 204, two slide rail mounting plates 204 are symmetrically mounted on the rectangular base 201, a guide rail protection cover 208 is mounted between the L-shaped connecting block 207 and the slide plate 203 and located above the slide rail 205, the guide rail protection cover 208 is mounted on the slide rail mounting plate 204 through the cover support plate 209, a rack 210 is mounted on one side of the guide rail protection cover 208, and a rack guard plate 211 is mounted on the outer side of the rack 210. The existing ground rail slide platform is not well protected, so the L-shaped connecting block structure 207 cooperates with multiple concave side baffles 202, which can more effectively protect the slide rail 205 and the slide 206 than the traditional side installation method of the protection plate.

[0022] An installation panel 213 is installed inside the rectangular base 201, and a ground rail power connector 214, a protective gas connector 215, an operating table power connector 217, a network cable connector 218 and a compressed air connector 219 are installed on the installation panel 213. An inlet groove 216 is opened below the installation panel 213 in the rectangular base 201.

[0023] A PC-end operating table 4 is provided on the outside of the tire frame 1; a placement plate 5 is fixedly connected to the top of the outer wall of the tire frame 1; a ground rail extension plate 6 is fixedly connected to one side of the outer wall of the robot body 3; a welding machine 7, an electric control cabinet 8 and a water tank 9 are fixedly connected to the top of the outer wall of the ground rail extension plate 6; in order to place the welding machine 7, the water tank 9, the electric control cabinet 8, etc. on the slide 203 to reduce the cable cost, the L-shaped connecting block 207 must be designed with a stronger bearing capacity to meet the use. If the entire part is directly processed according to the shape, the raw material consumption will be too much and the cost will increase accordingly; although the mechanism composed of multiple parts consumes less material, there are more processing steps and the strength will be reduced compared to the one-piece casting, so an one-piece casting structure is adopted, which has higher strength, less raw material consumption, simpler processing and lower costs.

[0024] The original cable layout uses a whole section of cable. If the workstation needs to be changed or moved after it is delivered to the customer site, the length of the reserved external cable will be insufficient. At this time, the whole section of cable needs to be pulled out from the drag chain and replaced. Replacing the cable in the drag chain is very troublesome, which greatly increases the labor and material costs. Therefore, the present invention sets the end of the rectangular base 201 as a built-in quick-change quick-plug structure, so that the length of the cable inside the workstation is always consistent, and the length of the external cable can be customized according to the needs. If the length is not enough for later use, it only needs to replace the external cable, which can reduce the labor and material costs; the designed built-in structure can also better protect the quick-change connector.

[0025] The robot body 3 includes a robot arm 301, a welding gun 302 and a wire feeder 303. The robot arm 301 is installed on the ground rail extension plate 6. The welding gun 302 is installed at one end of the robot arm 301. The wire feeder 303 is installed on the robot arm 301. A gun cleaning station bracket 308 is installed below the robot arm 301. A gun cleaning station 309 is installed at one end of the gun cleaning station bracket 308. A power box 307 is installed on one side of the robot arm 301. A ground rail drive motor 305 is installed on one side of the power box 307. An oil pump 304 is installed at one end of the ground rail drive motor 305. Wire grooves 306 are installed around the ground rail drive motor 305; a welding wire barrel 311 is installed on one side of the welding machine 7, and the welding wire barrel 311 contains barreled welding wire; a barrel wire fence 312 is provided on the outer wall of the bottom end of the welding wire barrel 311, and a wire feeding tube support frame 310 is installed on one side of the welding wire barrel 311. Placing the welding machine 7, water tank 9, electric control cabinet 8, etc. on the ground rail extension plate 6 shortens the distance from the robot body 3. The distance between the two is shortened, and the connecting cables used are also shortened. This not only greatly reduces the cost but also avoids the risks of twisting and abrasion caused by too many cables entering the drag chain. Then, a wire trough 306 is arranged between the two, so that the cables can be better protected, the wiring is also beautiful, and the maintenance is convenient;

[0026] The robot arm 301 is located above the welding gun 302 and is also equipped with a camera bracket, which includes a mounting plate 313 mounted on the robot arm 301, an extension plate 314 is mounted on the bottom end of the mounting plate 313, an up and down adjustment plate 315 is mounted on the extension plate 314, an angle adjustment block 316 is movably mounted on the up and down adjustment plate 315, a camera fixing plate 317 is fixedly provided at one end of the angle adjustment block 316, a 3D camera 320 is mounted on one side of the camera fixing plate 317 through a bakelite insulating plate 318, and the camera fixing plate 317, the bakelite insulating plate 318 and the 3D camera 320 are fixed by a plurality of bakelite insulating columns 319.

[0027] In order to further improve the welding efficiency of the workstation and meet the welding requirements of workpieces with diverse sizes, the present invention also configures a 3D camera 320 and a mounting bracket at the end of the robot; a PC-side operating table 4 (computer, camera controller, control software) is also provided at the near end of the workstation to connect the 3D camera 320; its advantages are: first, the extension plate 314 in the mounting bracket is designed with a row of mounting holes, and the upper and lower adjustment plates 315 are designed with slot waist holes for upper and lower adjustment and slots for plane rotation, which can be used together with the angle adjustment block 316 to perform upper and lower adjustment and plane angle rotation adjustment, so that the camera can obtain a better Good focal length and angle; its advantage 2, after adding 3D camera 320 and PC operating table 4, the operator can import the entire workstation and the workpiece model to be processed into the control software on the PC for 3D simulation. At the same time, the software system will also automatically generate welds and plan the optimal welding path. The simulation can predict and avoid collision accidents in welding work in advance, which can provide reliable protection for safe production. The autonomous generation of the optimal welding path can improve work speed and quality, reduce a lot of teaching time for personnel, and the PC can also perform remote operation and training, which can save a lot of travel expenses.
