Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary processing of vacuum tube tail foot frames, in particular to a tail foot frame strap spot welding device capable of automatically feeding and discharging materials. Background Technique

[0002] A solar water heater converts solar energy into heat energy, heating water from a low temperature to a high temperature to meet the hot water use of people in life and production. Solar water heaters are classified into vacuum tube solar water heaters and flat plate solar water heaters according to their structural forms. A household vacuum tube solar water heater mainly consists of a heat collecting tube, a water storage tank, a bracket, a tail foot frame and other related accessories. The conversion of solar energy into heat energy mainly depends on the heat collecting tube. The heat collecting tube utilizes the principle that hot water floats and cold water sinks to generate microcirculation of water to reach the required hot water.

[0003] The tail foot frame is a grooved strip tube with open structures on both side end faces and the bottom end face. Installation holes adapted to the vacuum tube are provided on the top end face. The openings at both ends are sealed by end caps, which is convenient for protecting the vacuum tube heat collecting tube and also convenient for operation, preventing other things from entering the tail support foot frame. At the same time, a vertically arranged strap needs to be spot welded and installed on the bottom opening of the tail foot frame to improve the strength and stability of the bottom surface of the tail foot frame.

[0004] At present, during the spot welding process of the tail foot frame strap, usually the tail foot frame is first placed and clamped on the workbench, and the spot welder is used to weld each strap on the tail foot frame at a certain interval. After welding is completed, the tail foot frame is removed from the workbench before continuing to weld the next tail foot frame. The welding speed is slow and the efficiency is low. Moreover, during welding, the workpiece is taken and placed manually, making it very inconvenient to take and place the workpiece, wasting a lot of time, affecting the welding efficiency of the workpiece, and there are certain safety hazards. Summary of the Invention

[0005] To solve the above problems, the utility model provides a tail foot frame strap spot welding device with high welding efficiency, less manual participation and capable of automatically feeding and discharging materials.

[0006] To achieve the above object, the utility model adopts the following technical scheme: A tail foot frame strap spot welding device capable of automatically feeding and discharging materials, comprising a conveying mechanism, a workbench, a feeding mechanism, a spot welding mechanism, a discharging mechanism, a strap feeding mechanism and a control panel.

[0010] The tape feeding mechanism includes a material bin, an installation frame and a tape feeding component. The material bin is arranged on the workbench in front of the upper and lower spot welding components of the spot welding mechanism and is opposite to both of them. The material bin is a hollow rectangular body structure with an open top surface, and the cavity size thereof is adapted to the size of the tape.

[0031] See Figure 1 and Figure 7 , the belt - feeding mechanism includes a material bin 18, a mounting frame 19 and a belt - feeding component. From Figure 1-3 it can be seen that the material bin 18 is arranged on the workbench 1 in front of the upper and lower spot - welding components of the spot - welding mechanism and is opposite to both of them. See Figure 7 , the material bin 18 is a hollow rectangular body structure with an open top surface. The cavity size of it is adapted to the size of the belt. A top - material cylinder is arranged at the bottom inside the material bin 18. The belt is placed in the cavity of the material bin 18 and above the telescopic end of the top - material cylinder. The mounting frame 19 is arranged on the workbench 1 on the right side of the material bin 18.

[0032] From Figure 1 and Figure 7It can be seen that a moving mechanism is provided on the bottom surface of the mounting bracket 19. The moving mechanism includes moving slide rails 24, moving sliders 25, and a moving cylinder 26. The number of the moving slide rails 24 is two, which are located on the workbench 1 below the mounting bracket 19. The moving sliders are installed on the bottom surface of the mounting bracket 19 and are slidably connected to the moving slide rails 24. The moving cylinder 26 is arranged on the workbench 1 on the right side of the mounting bracket 19. The telescopic end of the moving cylinder 26 is connected to the mounting bracket 19, and the moving cylinder 26 is connected to the control panel 2 through a wire.

[0033] See Figure 7 , the strap feeding component includes a strap cylinder group and a strap plate 20. The strap cylinder group is composed of a first strap cylinder 21 and a second strap cylinder 22. The first strap cylinder 21 is a slide table cylinder, which is arranged on the upper part of the end face of the mounting bracket 19 close to the material bin 18. Its slider can move back and forth between the front end face and the rear end face of the mounting bracket 19. The second strap cylinder 22 is installed on the slider of the first strap cylinder 21, and its telescopic end is arranged downward. The strap plate 20 is located below the second strap cylinder 22. One end of its top surface is connected to the telescopic end of the second strap cylinder 22, and an electromagnet suction block 23 is installed on the bottom surface of the other end. The strap plate 20 is in the same parallel line as the longitudinal direction of the material bin 18.

[0034] From Figure 1-3 It can be seen that the control panel 2 is set at a position on the workbench 1 that is convenient for operation, and the electric control components in each mechanism are connected and controlled to the control panel 2 through wires.

[0035] During use, the operator sends the tail foot bracket 27 into the feeding mechanism through the roller bracket 3. At this time, the switch is turned on on the control panel 2, and the driving motor drives the driving roller 6 to rotate to convey the tail foot bracket forward. The limiting wheels 7 limit the two sides of the tail foot bracket 27 to prevent it from deviating and keep it moving straight forward. When the number of rotation circles of the driving motor reaches the preset value, it stops rotating. At this time, the spot welding position of the tail foot bracket 27 is located between the upper spot welding head and the lower spot welding head.

[0036] After the driving motor stops rotating, the second strap cylinder 22 drives the strap plate 20 to move downward, so that the electromagnet suction block 23 on the strap plate 20 contacts the strap 28 in the material bin 18 and sucks it up. Then, the first strap cylinder 21 starts to work and moves the strap 28 onto the tail foot bracket 27 between the upper spot welding head 13 and the lower spot welding head.

[0037] After the strap 28 is placed, the strap plate 20 resets. The welding cylinder 12 and the lifting cylinder 15 work to make the upper spot welding head and the lower spot welding head cooperate to perform a welding action on the joint of the strap 28 and the tail foot bracket 27. After welding is completed, the upper spot welding head 13 and the lower spot welding head 16 reset, and the driving motor starts to work, repeating the above steps until all the welding work of the strap 28 is completed.

[0038] The above embodiments are only illustrative of the principles and effects of the present utility model, and are not intended to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
