In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0039] This embodiment provides a disassembly jig that can locally heat the product to be heated, has a small heating range, is easy to control the heating, shortens the heating time, has high heating efficiency and low heating cost. For example, the product to be heated can be an electronic product, such as a mobile phone, earphones, etc. In this embodiment, the electronic product is an earphone as an example for explanation.

[0040] like Figure 6 , Figure 8 and Fig. 9 As shown, the earphone includes an upper part and a lower part, and the upper part and the lower part need to be bonded together by glue. In this embodiment, the position where the upper part and the lower part are connected is called an assembly joint, and the area around the assembly joint is called an assembly joint area, that is, the assembly joint is located in the assembly joint area.

[0041] like Figures 1 to 9 As shown, the disassembly jig is provided with a product cavity 101, a heating tank 102, an air inlet channel 103 and an air outlet channel 104. The product cavity 101 is used to accommodate the product 10 to be heated. In some optional embodiments, the shape and size of the product cavity 101 match the shape and size of the electronic product so as to limit the position of the electronic product and prevent the electronic product from moving during the heating process.

[0042] like Figure 2As shown, the heating groove 102 is connected to the product cavity 101, and the heating groove 102 is configured to enclose the assembly joint area of ​​the product 10 to be heated to form a heating channel 105. The air inlet channel 103 and the air outlet channel 104 are both connected to the heating channel 105, and gas (such as high-temperature gas) can be input into the heating channel 105 through the air inlet channel 103 to heat the assembly joint 11. One end of the air outlet channel 104 extends to the outer wall of the disassembly fixture, so that the high-temperature gas in the heating channel 105 dissipates heat in the heating channel 105 and then flows out of the disassembly fixture through the air outlet channel 104. For example, the air inlet channel 103 in this embodiment is connected to a high-temperature gas source to provide high-temperature gas to the air inlet channel 103 through the high-temperature gas source. For example, the high-temperature gas source can be a hair dryer.

[0043] In the disassembly jig provided in the present embodiment, the product 10 to be heated is arranged in the product cavity 101, the heating groove 102 and the assembly joint area of ​​the product 10 to be heated located in the product cavity 101 are cooperated to form a heating channel 105, the air inlet channel 103 and the air outlet channel 104 are both connected to the heating channel 105, so that high-temperature gas can be introduced into the heating channel 105 through the air inlet channel 103, and the high-temperature gas directly heats the assembly joint 11 in the heating channel 105. By setting the heating channel 105, the movement trajectory of the high-temperature gas is controlled, so that other areas of the product 10 to be heated except the assembly joint area are not directly in contact with the high-temperature gas, thereby realizing local heating of the product 10 to be heated, having a smaller heating range, facilitating the control of heating, shortening the heating time, improving the heat utilization rate, and thus having higher heating efficiency and lower heating cost.

[0044] In some optional embodiments, such as Figure 2 As shown, the heating groove 102 is an annular groove. Figures 7 to 9 As shown, the heating channel 105 formed by the annular groove and the assembly joint area is an annular channel, so that the assembly joint 11 can be heated along the circumference of the product 10 to be heated, further improving the heating effect and heating efficiency of the assembly joint 11.

[0045] Alternatively, if Figure 1 As shown, the disassembly jig includes an upper mold 110 and a mold base 120 that are buckled and connected. For example, the upper mold 110 and the mold base 120 can be connected by a structure such as bolts. Figure 3 and Figure 4As shown, the surface of the upper mold 110 facing the mold base 120 is provided with a first heating sub-groove 111, and the surface of the mold base 120 facing the upper mold 110 is provided with a second heating sub-groove 121. The first heating sub-groove 111 and the second heating sub-groove 121 cooperate to form a heating groove 102, that is, the heating groove 102 includes the first heating sub-groove 111 arranged on the upper mold 110 and the second heating sub-groove 121 arranged on the mold base 120. Such an arrangement is convenient for manufacturing the heating groove 102 on the one hand, and convenient for cleaning the heating groove 102 on the other hand. In this embodiment, the first heating sub-groove 111, the second heating sub-groove 121 and the product 10 to be heated are surrounded to form a heating channel 105.

[0046] In some optional embodiments, the air inlet channel 103 is arranged on the upper mold 110, and one end of the air inlet channel 103105 is connected to the first heating sub-groove 111, and the other end of the air inlet channel 103 extends to the surface of the upper mold 110 facing away from the mold seat 120, so that the extension direction of the air inlet channel 103 can be set along the thickness direction of the upper mold 110, so that the air inlet channel 103 can be shorter, which reduces the flow resistance of the high-temperature gas on the one hand, and reduces the heat loss of the high-temperature gas in the air inlet channel 103 on the other hand.

[0047] Preferably, the air inlet channel 103 extends along the thickness direction of the disassembly jig. When the disassembly jig is in use, its thickness direction is the vertical direction. The air inlet channel 103 is set to extend along the thickness direction of the disassembly jig. The gas in the air inlet channel 103 can flow to the heating channel 105 under the action of its own gravity, reducing the driving force required for the gas flow.

[0048] Optionally, see Figure 4 The upper mold 110 is provided with a first air outlet groove 112 on the surface facing the mold base 120. Figure 3 As shown, the surface of the mold base 120 facing the upper mold 110 is provided with a second air outlet groove 122, and the first air outlet groove 112 and the second air outlet groove 122 cooperate to form an air outlet channel 104. By providing the first air outlet groove 112 and the second air outlet groove 122, when the upper mold 110 is separated from the mold base 120, the first air outlet groove 112 and the second air outlet groove 122 can be cleaned, thereby realizing the cleaning of the air outlet channel 104 and improving the convenience of cleaning.

[0049] As mentioned above, please continue to refer to Figure 4 The upper mold 110 is provided with a first product groove 113 on the surface facing the mold base 120. Figure 3As shown, the surface of the mold base 120 facing the upper mold 110 is provided with a second product groove 123, the first product groove 113 and the second product groove 123 cooperate to form a product cavity 101, the first product groove 113 is configured to position the upper half 12 of the product 10 to be heated, and the second product groove 123 is configured to position the lower half 13 of the product 10 to be heated. By providing the first product groove 113 and the second product groove 123, it is convenient to position the product 10 to be heated in the product cavity 101, and it is also convenient to clean the product cavity 101. The specific shapes of the first product groove 113 and the second product groove 123 can be determined according to the specific shapes of the upper half 12 and the lower half 13, and this embodiment does not limit this.

[0050] It should be noted that, by setting the first product groove 113 and the second product groove 123, the first product groove 113 is used to position the upper part 12, and the second product groove 123 is used to position the lower part 13, so that when the product 10 to be heated is disassembled, the upper mold 110 is separated from the mold base 120, which can drive the upper part 12 to separate from the lower part 13, thereby realizing the integration of heating and disassembly of the disassembly jig, and enriching the function of the disassembly jig.

[0051] Alternatively, if Figure 1 As shown, the disassembly jig further includes a fixing member 130, which is connected to the upper mold 110. The fixing member 130 has a portion protruding from the upper mold 110, and the upper mold 110 can be easily moved by connecting the portion, thereby facilitating the separation of the upper mold 110 from the mold base 120. In some optional embodiments, the fixing member 130 may be provided with an assembly hole, and the assembly hole is used to assemble a mobile device, so as to move the fixing member 130 and the upper mold 110 through the mobile device.

[0052] As mentioned above, a positioning hole (not shown) is provided on the surface of the mold base 120 facing the upper mold 110, one end of the fixing member 130 is located outside the upper mold 110, and the other end of the fixing member 130 passes through the upper mold 110 and is inserted into the positioning hole to realize the positioning of the upper mold 110 and the mold base 120, thereby ensuring the accuracy of the product cavity 101, the air inlet channel 103 and the air outlet channel 104 formed by the upper mold 110 and the mold base 120.

[0053] In some optional embodiments, such as Figure 5 As shown, the mold base 120 includes a middle mold 124 and a lower mold 125 that are buckled and connected, and the middle mold 124 is buckled and connected to the upper mold 110. For example, the middle mold 124 and the lower mold 125 can be detachably connected by bolts.

[0054] The surface of the middle mold 124 facing away from the lower mold 125 is provided with a first groove 1241, which is configured to position the block 13a of the lower half 13, and the first groove 1241 is connected to the second heating sub-groove 121. The surface of the middle mold 124 facing the lower mold 125 is provided with a second groove 1242 connected to the first groove 1241, and the surface of the lower mold 125 facing the middle mold 124 is provided with a third groove 1251, and the accommodation space formed by the cooperation of the second groove 1242 and the third groove 1251 is configured to position the column 13b of the lower half 13, so that the block 13a and the column 13b are fixed separately, thereby improving the fixing effect of the product 10 to be heated. It should be noted that the second groove 1242 extends to the outer wall of the middle mold 124, and the third groove 1251 extends to the outer wall of the lower mold 125. Part of the column 13b is located in the accommodating space formed by the second groove 1242 and the third groove 1251, so that the volume of the disassembly jig can be smaller and it is also convenient to take and place the lower part 13.

[0055] Alternatively, if Figure 1 As shown, a plurality of air inlet channels 103 are provided to increase the amount of high-temperature hot air provided to the heating channel 105 per unit time, further improving the heating efficiency. In this embodiment, a plurality of air inlet channels 103 are arranged at intervals along the annular heating channel 105. By way of example, three air inlet channels 103 are provided in this embodiment. By way of another example, an air inlet pipe may be provided in the air inlet channel 103, and the air inlet pipe is connected to a high-temperature air source.

[0056] Further optionally, if Figures 3 to 6 As shown, there are multiple outlet channels 104, so that the gas in the heating channel 105 can flow out through multiple outlet channels 104, avoiding the situation where the pressure is too high due to too much gas in the heating channel 105. Preferably, the number of the inlet channels 103 and the outlet channels 104 are the same and the inner diameter is the same.

[0057] In this embodiment, the air outlet channel 104 extends in a direction perpendicular to the thickness direction of the disassembly jig, so that the air outlet channel 104 can be shorter, thereby avoiding heat waste.

[0058] For example, an outlet pipe may be installed in the outlet channel 104 to facilitate the outlet of high-temperature gas.

[0059] In some optional embodiments, the intersection of the air inlet channel 103 and the heating groove 102 does not overlap with the intersection of the air outlet channel 104 and the heating groove 102, that is, the intersection of the air inlet channel 103 and the heating groove 102 and the intersection of the air outlet channel 104 and the heating groove 102 are located at different positions of the heating groove 102, so that the high-temperature gas flowing into the heating channel 105 from the air inlet channel 103 can flow along the heating channel 105 for a distance without flowing out directly from the air outlet channel 104, thereby improving the thermal energy utilization rate and the heating reliability.

[0060] When the disassembly jig provided in this embodiment is used to disassemble the product 10 to be heated:

[0061] The product 10 to be heated is placed in the first groove 1241, and the column 13b of the heated product is passed through the accommodation space formed by the second groove 1242 and the third groove 1251. At this time, the block 13a of the product 10 to be heated is limited by the first groove 1241. After that, the upper mold 110 and the middle mold 124 are aligned, and the upper half 12 is aligned with the first product groove 113, and the upper mold 110 and the middle mold 124 are buckled to form a heating channel 105. After that, high-temperature gas is introduced into the heating channel 105 through the air inlet channel 103, and the high-temperature gas directly heats the assembly joint 11, and the heating temperature and heating time are controlled. After the preset heating time, the glue melts. At this time, the upper mold 110 is driven by the fixing member 130 to move away from the middle mold 124, and the upper half 12 moves with the upper mold 110, so that the upper half 12 and the lower half 13 are separated.

[0062] The disassembly jig provided in this embodiment facilitates the subsequent disassembly and assembly of the product to be heated 10 connected by glue bonding. This embodiment performs high-temperature gas heating on a specific part (i.e., the assembly joint 11), controls the movement trajectory of the gas, protects other parts of the product to be heated 10 from being corroded by the high-temperature gas, and reduces the damage rate of the product to be heated 10. Heating with high-temperature gas at the product assembly joint 11 can effectively improve the heating efficiency and shorten the time cost required for heating. By opening an outlet channel 104 for high-temperature gas discharge, the high-temperature gas can enter and exit unimpeded. After heating for a predetermined time, the upper mold 110 is separated from the lower mold 125 by pulling through the fixing part 130. In addition, this embodiment only requires a hair dryer to provide high-temperature gas, has the advantage of concentrated heating, and the heating time is short, there is no need to replace equipment, and the heating temperature is easy to control.
