Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0026] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.
[0027] In some embodiments, please refer to the accompanying drawings. Figures 1-4 The high-precision welding and positioning fixture for the main control board of the charging pile includes a base plate 1, a flexible centering clamping mechanism 2 and a clamping detection mechanism 3; the flexible centering clamping mechanism 2 for positioning and clamping the main control board of the charging pile is installed on the upper rear side of the base plate 1.
[0028] like Figure 1 As shown, the flexible centering clamping mechanism 2 includes a drive assembly 21, a fixed clamping assembly 22, a movable clamping assembly 23, a horizontal lateral movement assembly, a horizontal vertical movement assembly, and a tension spring 26. The horizontal lateral movement assembly and the horizontal vertical movement assembly have the same structure and function, only differing in their installation positions. The horizontal vertical movement assembly is installed on the upper rear side of the substrate 1. The horizontal lateral movement assembly is installed on the upper left front side of the substrate 1. The drive assembly 21 is installed on the horizontal vertical movement assembly. The fixed clamping assembly 22 is installed on the upper right front side of the substrate 1. The movable clamping assembly 23 is installed on the horizontal lateral movement assembly. The tension spring 26 is connected to the fixed clamping assembly 22 and the movable clamping assembly 23.
[0029] A clamping detection mechanism 3 is also installed on the upper front side of the substrate 1 to detect whether the fixed clamping assembly 22 and the movable clamping assembly 23 are performing clamping actions;
[0030] In this invention, the drive assembly 21 moves forward along the horizontal vertical moving assembly. During this movement, the drive assembly 21 drives the movable clamping assembly 23 to move, causing the movable clamping assembly 23 to move away from the fixed clamping assembly 22 along the horizontal horizontal moving assembly. The movement of the movable clamping assembly 23 stretches the tension spring 26. The robotic arm then pushes the right side of the charging pile main control board into the fixed clamping assembly 22. The drive assembly 21 then resets, and the tension spring 26 returns to its original position, causing the movable clamping assembly 23 to reset to the right and abut against the left side of the charging pile main control board. At this point, both sides of the charging pile main control board are fixed by the movable clamping assembly 23 and the fixed clamping assembly 22. Welding operations can then be performed on the charging pile main control board.
[0031] Furthermore, the clamping detection mechanism 3 can accurately determine whether the movable clamping component 23 has moved to the left, further improving the clamping stability of the device on the charging pile main control board. Through the cooperation of the movable clamping component 23 and the fixed clamping component 22, the device can perform faster and more accurate positioning and clamping of the charging pile main control board, reducing the operator's extra workload in positioning the welding parts, and ensuring that the welding parts are in the set welding point position. The operation is simple, further improving the practicality of the device.
[0032] like Figure 3 As shown, both the horizontal lateral movement component and the horizontal vertical movement component are composed of a guide rail 24 and a damping sliding block 25. The guide rail 24 of the horizontal vertical movement component is fixedly installed on the upper rear side of the base plate 1; the guide rail 24 of the horizontal lateral movement component is fixedly installed on the upper left front side of the base plate 1; the damping sliding block 25 is slidably connected to the guide rail 24.
[0033] like Figure 3 As shown, the drive assembly 21 includes a cylinder 211 and a push plate 212. The cylinder 211 is fixedly installed on the upper rear side of the base plate 1. The push plate 212 is fixedly installed on the output end of the cylinder 211. The push plate 212 is fixedly connected to the damping sliding block 25 of the horizontal and vertical moving assembly. A sliding arc groove 213 is provided on the left side of the front side of the push plate 212.
[0034] like Figure 3 As shown, the fixing clamping assembly 22 includes a fixing block 221, a fixing rod 222, and a clamping plate 223; the fixing block 221 is fixedly installed on the upper front right side of the base plate 1; the fixing rod 222 is fixedly installed on the upper right side of the fixing block 221; and the clamping plate 223 is fixedly installed on the front end of the fixing rod 222.
[0035] like Figure 3 As shown, the movable clamping assembly 23 includes a movable plate 231, a rotating wheel 232, a second fixed rod 233, and a second clamping plate 234; the movable plate 231 is fixedly installed on the damping sliding block 25 of the horizontal lateral movement assembly; the rotating wheel 232 is rotatably installed on the upper rear right side of the movable plate 231; the second fixed rod 233 is fixedly installed on the upper left side of the movable plate 231; and the second clamping plate 234 is fixedly installed on the front end of the second fixed rod 233.
[0036] The left end of the tension spring 26 is fixedly connected to the movable plate 231; the right end of the tension spring 26 is fixedly connected to the fixed block 221.
[0037] like Figure 4 As shown, the clamping and detection mechanism 3 includes a fixed cylinder 31, a pressure rod 32, a return spring 33, and a small column-type pressure sensor 34; the fixed cylinder 31 is fixedly installed on the upper front left side of the base plate 1; the pressure rod 32 is slidably connected to the fixed cylinder 31; one end of the return spring 33 is fixedly connected to the inner wall of the fixed cylinder 31; the other end of the return spring 33 is fixedly connected to the pressure rod 32; a small column-type pressure sensor 34 is fixedly installed at the inner bottom of the fixed cylinder 31; an inclined surface is provided on the upper right side of the pressure rod 32;
[0038] In this invention, the cylinder 211 works to push the push plate 212 to slide forward along the guide rail 24 following the damping sliding block 25 of the horizontal vertical moving component until the sliding arc groove 213 at the front end of the push plate 212 contacts the rotating wheel 232 on the movable plate 231. The push plate 212 then pushes the movable plate 231 to slide to the left along the guide rail 24 following the damping sliding block 25 of the horizontal transverse moving component. During the sliding process, the movable plate 231 also stretches the tension spring 26 to the left.
[0039] The robotic arm then pushes the right side of the charging pile main control board into the clamping plate 223. Then, the cylinder 211 drives the push plate 212 to reset backward. Then, the tension spring 26 returns to its original position, causing the movable plate 231 to move to the right and reset. During the movement, the clamping plate 234 will abut against the left side of the charging pile main control board. At this time, the left and right sides of the charging pile main control board will be fixed by the clamping plate 234 and the clamping plate 223.
[0040] Furthermore, as the movable plate 231 moves the clamping plate 234 to the left, the clamping plate 234 will touch the inclined surface on the upper right side of the pressure rod 32, and drive the pressure rod 32 to move downward along the fixed cylinder 31. At this time, the pressure rod 32 will compress the return spring 33 downward until the lower end of the pressure rod 32 touches the small column pressure sensor 34. The pressure reading detected by the small column pressure sensor 34 changes, and it can be determined that the movable plate 231 has performed the action of moving to the left. If the pressure reading detected by the small column pressure sensor 34 does not change, it can remind the staff that there is an abnormality in the welding of the main control board, which makes it convenient for the operator to inspect and maintain the feeding part or the clamping part, and further improves the clamping stability of the device for the charging pile main control board.
[0041] Example 2: In some embodiments, such as Figure 5 As shown, in a preferred embodiment of this utility model, the clamping plate 223 and the clamping plate 234 are provided with an air inlet chamber; an air pipe 4 is fixedly installed at the far ends of the clamping plate 223 and the clamping plate 234; a plurality of air holes 5 are provided at the near ends of the clamping plate 223 and the clamping plate 234; the air pipe 4 is connected to the air inlet chamber; the air inlet chamber is connected to the air holes 5; the outer end of the air pipe 4 is connected to the fan.
[0042] In this utility model, when the main control board of the charging pile is soldered, the soldering method is usually adopted. Soldering generally generates a high temperature of 320℃-350℃, but the temperature resistance of the electronic components on the main control board of the charging pile is usually less than 105℃. At this time, the high temperature generated by soldering can easily damage the electronic components.
[0043] After clamping plate 223 and clamping plate 234 clamp and fix the main control board of the charging pile, the fan works to deliver cold air into the air pipe 4. The cold air enters the air inlet chamber and is then discharged through the air hole 5 to the clamping position of the main control board. This reduces the temperature generated when the main control board of the charging pile is soldered with a soldering iron, achieves effective temperature control, improves heat dissipation efficiency, and avoids high temperature damage to the electronic components set on the main control board of the charging pile.
[0044] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
