The two guide rails 2 are symmetrically arranged on the upper surface of the tool base 1, the conveying member 3 is evenly arranged on the tool base 1 for conveying the microchannel flat tube, the detection member 4 is arranged on the guide rail 2 for detecting the flatness of the microchannel flat tube, the detection member 4 is connected to the positive electrode of the power supply 6 through the first wire 5, the negative electrode of the power supply 6 is connected to one end of the buzzer 8 through the second wire 7, and the other end of the buzzer 8 is connected to the conveying member 3 through the third wire 9.
[0022] The tooling base 1 is a rectangular parallelepiped structure, which serves as the installation base of the tooling, and the entire tooling can also be installed on any work platform through the tooling base 1 to facilitate the use of the tooling. Two guide rails 2 are symmetrically fixedly installed in the middle position of the upper surface of the tooling base 1, and conveying parts 3 are evenly arranged on the upper surface of the tooling base 1.

The other end of the buzzer 8 is connected to a third wire 9, and the other end of the third wire 9 is connected to the conveying part 3. When When the finished straight material microchannel flat tube 10 is conveyed on the conveying member 3, the lower surface of the finished straight material microchannel flat tube 10 contacts the conveying member 3. If the upper surface of the finished straight material microchannel flat tube 10 contacts the detection member 4, the finished straight material microchannel flat tube 10, the detection member 4, the power supply 6, the buzzer 8 and the conveying member 3 form a passage, and the buzzer 8 works, that is, the flatness of the finished straight material microchannel flat tube 10 is unqualified. If the upper surface of the finished straight material microchannel flat tube 10 does not contact the detection member 4, the circuit between the finished straight material microchannel flat tube 10 and the detection member 4 is broken, and the buzzer 8 does not work, that is, the flatness of the finished straight material microchannel flat tube 10 is qualified.

[0023] Specifically, the conveying member 3 includes eight brackets 31, four rollers 32 and three fourth wires 33. The eight brackets 31 are symmetrically arranged on both sides of the upper surface of the tooling base 1. The four rollers 32 are respectively set on the eight brackets 31. The four rollers 32 are connected in series through three fourth wires 33. The end of the first wire 5 away from the buzzer 8 is connected to the end of the roller 32 away from the fourth wire 33.
[0024] The conveying member 3 is composed of eight brackets 31, four rollers 32 and three fourth wires 33. Eight brackets 31 are symmetrically fixedly installed on the left and right sides of the upper surface of the tooling base 1. Four rollers 32 are rotatably installed on the eight brackets 31 through metal bearings (not shown in the figure). The rollers 32 are made of metal material. The four rollers 32 are connected in series through three fourth wires 33, so that the lower surface of the microchannel flat tube can be connected to the buzzer 8 through the rollers 32. It should be noted that in order to prevent the fourth wires 33 from affecting the normal rotation of the rollers 32, the fourth wires 33 can be connected to the metal bearings.
[0025] Specifically, the detection component 4 includes a slider 41, a detection base 42, an insulating block 43 and a conductive probe 44, the slider 41 is arranged on the guide rail 2, the detection base 42 is arranged on the slider 41, the insulating block 43 is arranged on the detection base 42, the conductive probe 44 is arranged on the insulating block 43, and the conductive probe 44 is connected to the positive pole of the power supply 6 through the first wire 5.

[0027] Furthermore, the bracket 31 in this embodiment is made of insulating materials, such as wood, plastic, etc., which plays a role in isolating electric current to ensure the safety of workers.
[0028] Furthermore, the voltage of the power supply 6 in this embodiment is 12V, and the use of a low-voltage power supply 6 further ensures the safety of the staff.
[0029] When in use, the staff can install the conductive probe 44 according to the flatness tolerance standard required by the qualified finished straight material microchannel flat tube, and debug the conductive probe 44 so that the maximum distance between the bottom of the conductive probe 44 and the upper surface of the microchannel flat tube is H. After completing the debugging, turn on the power supply 6, and the staff will place the finished straight material microchannel flat tubes 10 to be tested one by one on the roller 32. The roller 32 transfers the finished straight material microchannel flat tube 10 to the bottom of the conductive probe 44. If the upper surface of the finished straight material microchannel flat tube 10 contacts the bottom of the conductive probe 44, the finished straight material microchannel flat tube 10, the conductive probe 44, the power supply 6, the buzzer 8 and the roller 32 are in contact with each other.
