This heating device can improve the repair efficiency of components and is beneficial to the batch repair of components.
[0031] The above-mentioned first heating jig 10 and the second heating jig 20 are arranged facing each other. In this embodiment, the object to be heated is located between the first heating jig 10 and the second heating jig 20, and is used to heat the opposite sides of the object to be heated respectively.
[0032] It should be noted that the above-mentioned object to be heated can be a substrate with components mounted on it.

Of course, in addition to being applied to the SMT process, the above-mentioned heating device can also be applied to other fields. The application scenario of the heating device in this application is not limited.
[0033] The above-mentioned power supply 30 is electrically connected to the first heating jig 10 and the second heating jig 20 respectively.

[0036] Please refer to Figure 1 and Figure 4 Optionally, the first heating jig 10 includes a first base 11 and a first heating plate 12. The first base 11 is electrically connected to the power supply 30, the first heating plate 12 is electrically connected to the first base 11, and the first heating plate 12 is used to heat one side of the object to be heated.
[0037] It should be noted that the first heating plate 12 is located between the first base 11 and the second heating jig 20, and the first heating jig 10 specifically heats the object to be heated through the first heating plate 12.
[0038] The first base 11 is electrically connected to the power supply 30 and the first heating plate 12 respectively. The power supply 30 supplies power to the first heating plate 12 through the first base 11, so as to heat the object to be heated through the first heating plate 12.
[0039] Optionally, a first heating coil is provided in the first heating plate 12, and the first heating plate 12 has two first electrode holes 121; two first electrodes 111 protrude from one side of the first base 11 facing the first heating plate 12, and the two first electrodes 111 respectively pass through the two first electrode holes 121 and are electrically connected to the opposite ends of the first heating coil respectively; the polarities of the two first electrodes 111 are opposite, and the two first electrodes 111 are respectively electrically connected to the power supply 30.
[0040] In this embodiment, the first heating coil is disposed inside the first heating plate 12, and both ends of the first heating coil are respectively exposed from the two first electrode holes 121. In this way, when the two first electrodes 111 on the first base 11 are respectively inserted into the two first electrode holes 121, it is convenient for the two first electrodes 111 to be respectively electrically connected to both ends of the first heating coil, so as to energize and heat the first heating coil.
[0041] Similarly, please refer to Figure 1 and Figure 3 Optionally, the second heating fixture 20 includes a second base 21 and a second heating plate 22. The second base 21 is electrically connected to the power supply 30, and the second heating plate 22 is electrically connected to the second base 21. The second heating plate 22 is located on the side of the second base 21 close to the first heating plate 12, and the second heating plate 22 is used to heat the side of the object to be heated facing away from the first heating plate 12.
[0042] That is to say, the second heating fixture 20 heats the object to be heated through the second heating plate 22. Among them, the second base 21 is electrically connected to the second heating plate 22 and the power supply 30 respectively. In this way, the power supply 30 can supply power to the second heating plate 22 through the second base 21, so as to realize the heating of the object to be heated by the second heating plate 22.
[0043] Optionally, a second heating coil is disposed inside the second heating plate 22, and the second heating plate 22 has two second electrode holes 221. Two second electrodes 211 protrude from the side of the second base 21 facing the second heating plate 22. The two second electrodes 211 are respectively inserted into the two second electrode holes 221 and are respectively electrically connected to the opposite ends of the second heating coil. The polarities of the two second electrodes 211 are opposite, and the two second electrodes 211 are respectively electrically connected to the power supply 30.
[0044] That is, the second heating plate 22 also realizes the power supply to the second heating coil by disposing a second heating coil inside, and the two second electrodes 211 respectively extend into the two second electrode holes 221 and are respectively electrically connected to both ends of the second heating coil.
[0045] In addition, in this embodiment, optionally, the orthographic projections of the first heating plate 12 and the second heating plate 22 on the first base 11 coincide. In this way, the first heating plate 12 and the second heating plate 22 can respectively provide heating areas with the same area on the opposite sides of the object to be heated, which is beneficial to the heating uniformity of the object to be heated.

[0047] It should be noted that one end of the mounting post 40 can protrude from one of the bases, and the other end can pass through the mounting hole 41 in the other base. For example, the mounting post 40 protrudes from the first base 11, and the other end extends towards the second base 21 and extends into the mounting hole 41 of the second base 21. It should be noted that the mounting hole 41 can be a blind hole or a through hole. When the mounting hole 41 is a through hole, the mounting post 40 can be in interference fit with the through hole.
[0048] In order to prevent the object to be heated from falling or shifting in position between the first heating plate 12 and the second heating plate 22 when the first heating fixture 10 and the second heating fixture 20 are respectively pressed on the opposite sides of the object to be heated, optionally, please refer to Figure 1 and Figure 2 As shown, the heating device further includes a limiting retaining wall 50. The limiting retaining wall 50 is located between the first base 11 and the second base 21, and the limiting retaining wall 50 is located on the outer periphery of the first heating plate 12 for radially limiting the object to be heated.

In this way, the object to be heated between the first heating plate 12 and the second heating plate 22 can be radially limited to prevent the object to be heated from shifting in position.
[0050] It should be noted that in this embodiment, the limiting retaining wall 50 can protrude from the first base 11 or from the second base 21. When the limiting retaining wall 50 protrudes from the first base 11, the height of the limiting retaining wall 50 should be greater than the height of the first heating plate 12; when the limiting retaining wall 50 protrudes from the second base 21, the height of the limiting retaining wall 50 should be greater than the height of the second heating plate 22.
