[0089] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0090] Example

[0091] See also Figure 1 The present embodiment provides a hot melt pressing device 1000, which includes an upper cover 200, a bottom frame 500 and an internal device 100, wherein the upper cover 200 and the internal device 100 are mounted on the bottom frame 500. The upper cover 200 is provided with an industrial computer 400 and a temperature controller 300, wherein the industrial computer 400 is used to control the pressing action of the hot melt pressing device 1000, and the temperature controller 300 is used to control the pressing temperature of the hot melt pressing device 1000, so that the target part can be hot melt pressed to the workpiece at a certain temperature to form a composite part.

[0092] See also Figures 2 to 4 In this embodiment, the internal device 100 includes a heating component 21, a fixture component 22 and a pressing component 23. The heating component 21 includes a carrier 211, and the carrier 211 is used to carry the target part 10 upward along the vertical direction Z. The heating component 21 can heat the target part 10. The fixture component 22 is used to carry the workpiece 20, and to carry the workpiece 20 above the target part 10 along the vertical direction Z. The pressing component 23 is used to press the fixture component 22 and the workpiece 20 down along the vertical direction Z, so that the workpiece 20 presses down the heated target part 10 until the target part 10 is hot-melted and pressed at the set position S of the workpiece 20.

[0093] In this embodiment, the setting position S is the position where the workpiece 20 is heat-melted and pressed to the target part 10, so that the target part 10 is heat-melted and pressed to the workpiece 20 to form a composite part.

[0094] In this embodiment, both sides of the workpiece 20 along the vertical direction Z need to be hot-melt pressed together with the target part 10. The heating assembly 21, the fixture assembly 22 and the pressing assembly 23 are respectively provided with two groups, one of which is used to press the target part 10 to the set position S on the first side of the workpiece 20 along the vertical direction Z, and the other group is used to press the target part 10 to the set position S on the second side of the workpiece 20 along the vertical direction Z.

[0095] See also Figure 3 and Figure 4In this embodiment, the workpiece 20 is a plastic part, such as a plastic pallet. The workpiece 20 is provided with a reserved hole 201. The target part 10 is a riveted part, such as a metal part, and the riveted part is an annular structure. The riveted part can be hot-melted and pressed into the reserved hole 201 with its outer annular surface 101 to form a composite part.

[0096] In this embodiment, the reserved hole 201 is disposed at a set position S of the workpiece 20 .

[0097] In this embodiment, the diameter of the outer ring surface 101 of the riveted part is slightly larger than the diameter of the reserved hole 201, the hot melt pressing temperature is 325°C, the melting temperature of the workpiece 20 is 225-275°C, and the target part 10 is made of a high melting point material (such as steel or other metals). During hot melt pressing, the target part 10 is heated to the hot melt pressing temperature, the target part 10 remains in a solid state, and the workpiece 20 is pressed down so that the target part 10 melts the material near the reserved hole 201 of the workpiece 20, so that the target part 10 can be squeezed into the melted and expanded reserved hole 201. After cooling, the target part 10 is wrapped and fixed by the re-solidified workpiece 20, thereby obtaining a composite part in which the workpiece 20 and the target part 10 meet.

[0098] In other embodiments, other materials with different melting points may also be used, with the high melting point material being used as the target part and the low melting point material being used as the workpiece for hot-melt pressing.

[0099] See also Figure 4 and Figure 5 In this embodiment, the heating component 21 also includes a heat insulation board 213 and a heating element 214.

One end of the supporting member 211 is thermally coupled to the heating element 214, and the other end extends out of the upper surface of the heat insulation board 213 from the first through hole 2131.

[0100] In this embodiment, the heating element 214 is a heating rod 215. In other embodiments, the heating element may also be other heating structures.

[0101] In this embodiment, the heating assembly 21 also includes a thermocouple 216, and the heating rod 215 is thermally coupled to the carrier 211. When in use, the heating rod 215 generates heat and transfers the heat to the carrier 211, and the carrier 211 supports and heats the target part 10. The thermocouple 216 can control the temperature of the heating rod 215 so that the target part 10 is within the hot melt temperature range. Among them, the hot melt temperature refers to the temperature at which the workpiece 20 melts. And the temperature needs to ensure that when the target part 10 is pressed onto the workpiece 20, the workpiece 20 and the part that contacts the target part 10 can be melted and the other parts of the workpiece 20 are not melted.

[0102] In this embodiment, a heat insulation plate 213 is provided so that only the temperature of the support 211 on one side of the heating assembly 21 close to the workpiece 20 along the vertical direction Z is greater than the melting temperature of the workpiece 20, thereby preventing other parts of the workpiece 20 from melting and causing defects.

[0103] See also Figure 4 , Figure 5 and Figure 6 In this embodiment, the bearing member 211 includes an extension end 212, which extends out of the upper surface of the heat insulation board 213 to support the target member 10.

The inner annular surface 102 (see Figure 3 ) is sleeved on the positioning member 2122, and the bottom surface of the target member 10 is supported on the abutting surface 2111 to position the target member 10.

[0104] In this embodiment, the abutting surface 2111 abuts against the surface of the target part 10 along the vertical direction Z facing the abutting surface 2111 , and then the target part 10 is positioned by the positioning member 2122 , so that the target part 10 is fixed on the protruding end 212 .

[0105] In this embodiment, the diameter of the free end of the positioning member 2122 gradually decreases and is in a pointed cone shape to facilitate the assembly of the target member 10 .

[0106] In this embodiment, the positioning member 2122 is rod-shaped, and the inner annular surface 102 of the target member 10 can be plugged into and fitted on the outside of the positioning member 2122 .

[0107] In other embodiments, the protruding end may also be configured to have other shapes for supporting target parts with different shapes, for example, a groove may be configured at the protruding end to position and support the target part.

[0108] See also Figure 7 and Figure 8 In this embodiment, the fixture assembly 22 includes a fixture 221, the fixture 221 has a first hole 2211, and the workpiece 20 is installed between the side walls 2212 of the first hole 2211. The side wall 2212 is provided with a boss 2213 protruding toward the inner side of the first hole 2211, and the boss 2213 is used to support the workpiece 20 along the vertical direction Z.

[0111] In this embodiment, the air blowing device 24 starts blowing air after the hot melt pressing is completed to cool the composite part so that the target part 10 is fixed inside the workpiece 20 and does not fall out.

[0112] See also Figure 7 In this embodiment, the fixture assembly 22 further includes a support plate 222, a spring 223 and a cylinder 224.

[0114] In this embodiment, the cylinder 224 is cut off during the hot melt pressing and does not maintain support to avoid affecting the downward pressure of the fixture assembly 22. After the hot melt pressing is completed, the cylinder 224 is pressurized to lift the fixture 221 to separate the fixture 221 from the heating assembly 21.

[0115] In this embodiment, the support plate 222 is further provided with a mounting groove 2221, and the mounting groove 2221 is used to cooperate with the fixing fixture 221.

The pressing block 231 has a lower pressing surface 2312, and the lower pressing surface 2312 abuts against the jig 221 and the workpiece 20 at the same time.

[0118] In this embodiment, the pressing block 231 presses down the fixture 221 and the workpiece 20 to prevent the workpiece 20 from being deformed by force during hot-melt pressing and causing defects.

[0119] In another embodiment, see Fig.11 The pressing block 231 includes a lower pressing surface 2312 and a protruding portion 2311. The lower pressing surface 2312 abuts against the fixture 221, and the protruding portion 2311 abuts against the workpiece 20 (see Figure 4 ) to prevent defects in the workpiece 20 during hot melt pressing.

[0120] See also Figures 12 to 15 In this embodiment, the hot melt pressing device further includes a feeding assembly 25, a bottom plate 261, a track 262 and a detection assembly 27.
