For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0051] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0052] See also Figure 1 , an embodiment of the present application provides a heat-insulating pressing device 100. The heat-insulating pressing device 100 is used to heat-press a workpiece 200 onto a product 300. In this embodiment, a hot melt adhesive (not shown), such as HAF tape, is provided between the workpiece 200 and the product 300. When the heat-insulating pressing device 100 heat-presses the workpiece 200, the hot melt adhesive between the workpiece 200 and the product 300 becomes sticky due to the heat, thereby bonding the workpiece 200 and the product 300 together.

[0053] See also Figure 2 In this embodiment, a groove 301 for accommodating the workpiece 200 is provided on the product 300, a hot melt adhesive is arranged at the bottom of the groove 301, and the workpiece 200 is placed on the hot melt adhesive.

[0054] See also Figure 1 and Figure 3, the heat-insulating pressing device 100 includes a base 10 and a hot pressing mechanism 20. The hot pressing mechanism 20 includes a pressing head assembly 21 and a heating assembly 22. The pressing head assembly 21 includes a pressing head 211 and a heat-insulating sleeve 212. The pressing head 211 is connected to the base 10. The heating assembly 22 is connected to the pressing head 211 and is used to heat the pressing head 211. The heat-insulating sleeve 212 can be made of glass ceramics. The heat-insulating sleeve 212 is sleeved on the pressing head 211, and the pressing head 211 is used to abut against the heat-insulating sleeve 212 protruding from one end of the workpiece 200. In this embodiment, the number of the pressing head assembly 21 and the heating assembly 22 are both two. The two heating assemblies 22 are used to heat the two pressing head assemblies 21 respectively. The two pressing head assemblies 21 can simultaneously heat the two workpieces 200 on the product 300, wherein the two workpieces 200 hot-pressed by the two pressing head assemblies 21 can be the same or different.

[0055] During the implementation of the heat-insulating pressing device 100, the heating component 22 first heats the pressing head 211, and then makes the pressing head 211 contact the workpiece 200, so as to press the workpiece 200 against the product 300 and keep it for a period of time. At the same time, the heat-insulating sleeve 212 contacts the product 300. During the process of the pressing head 211 hot-pressing the workpiece 200, the pressing head 211 transfers heat to the hot melt adhesive through the workpiece 200, so that the hot melt adhesive becomes sticky when heated to bond the workpiece 200 and the product 300. In this way, during the hot-pressing process of the pressing head component 21, the pressing head 211 is used to press the workpiece 200, so as to heat the hot melt adhesive through the workpiece 200, so that the workpiece 200 and the product 300 are bonded together. Since the pressing head 211 does not contact the product 300, the pressing head 211 is prevented from causing burns to the product 300. The heat insulating sleeve 212 is used to press the product 300. The heat insulating sleeve 212 limits the pressing head 211. When the heat insulating sleeve 212 presses the product 300, the pressing head 211 will no longer press the workpiece 200, so as to prevent the pressing head 211 from over-pressing the workpiece 200. In addition, the heat insulating sleeve 212 plays a role of heat insulation, which can avoid burning the product 300 when pressing the product 300. Since the heat insulating sleeve 212 is made of glass ceramics, the heat insulating sleeve 212 is resistant to high temperatures and is not easy to deform.

[0056] See also Figure 1 and Figure 3The base 10 includes a bottom plate 11, a heat insulating plate 12 and a connecting plate 13. The bottom plate 11 can be connected to the cylinder. The bottom plate 11 drives the entire heat-insulating pressing device 100 to approach the workpiece 200 and the product 300 to perform hot pressing operations under the drive of the cylinder. The heat insulating plate 12 is connected to the bottom plate 11. The material of the heat insulating plate 12 can be synthetic stone. The heat insulating plate 12 plays a role of heat insulation to prevent the bottom plate 11 from overheating. The connecting plate 13 is connected to the side of the heat insulating plate 12 away from the bottom plate 11. The pressure head 211 is connected to the connecting plate 13. The connecting plate 13 serves the purpose of connecting the pressure head 211 and the bottom plate 11. When the cylinder drives the bottom plate 11 to move, the bottom plate 11 drives the pressure head 211 to move through the connecting plate 13 to perform hot pressing on the workpiece 200.

[0057] In order to improve the heat insulation effect between the pressure head 211 and the bottom plate 11, a heat insulation groove 121 is provided on the side of the heat insulation board 12 facing the connecting plate 13. The number of the heat insulation grooves 121 can be multiple, and the multiple heat insulation grooves 121 can be interconnected. The connecting plate 13 is covered on the heat insulation grooves 121. In this way, after the heat insulation grooves 121 are provided on the heat insulation board 12, the contact area between the heat insulation board 12 and the connecting plate 13 is reduced, which is conducive to reducing the heat transfer efficiency of the connecting plate 13 to the heat insulation board 12 and improving the heat insulation effect of the heat insulation board 12.

[0058] See also Figure 1 , Figure 3 and Figure 4 The pressure head assembly 21 further includes a guide member 213 and an elastic member 214. The guide member 213 is connected to the connecting plate 13 of the base 10. The pressure head 211 is slidably connected to the guide member 213. The pressure head 211 is connected to the base 10 through the guide member 213. The elastic member 214 is a spring. Specifically, there can be a plurality of elastic members 214. The plurality of elastic members 214 are arranged at intervals. The connecting plate 13 is provided with a plurality of installation grooves 131 arranged at intervals. The plurality of elastic members 214 are respectively inserted into the plurality of installation grooves 131. The two ends of each elastic member 214 are respectively in contact with the connecting plate 13 of the base 10 and the pressure head 211. Thus, by providing an elastic member 214 between the base 10 and the pressing head 211, when the pressing head 211 presses against the workpiece 200, the pressing head 211 elastically presses against the workpiece 200 under the elastic action of the elastic member 214, and the elastic member 214 acts as a buffer to prevent the pressing head 211 from making hard contact with the workpiece 200, and prevents the pressing head 211 from crushing the workpiece 200. When the pressing head 211 presses against the workpiece 200, the pressing head 211 slides along the guide member 213, and the guide member 213 guides the pressing head 211, so that the pressing head 211 will not deviate when pressing against the workpiece 200.

[0059] The pressure head 211 includes a connecting body 215, a pressing part 216 and a sliding part 217. The connecting body 215 is a block structure, the pressing part 216 is a columnar structure, the pressing part 216 is connected to the side of the connecting body 215 away from the base 10, the heat insulation sleeve 212 is sleeved on the pressing part 216 and one end of the heat insulation sleeve 212 is fixed to the connecting body 215 by bolts, and the pressing part 216 protrudes from the heat insulation sleeve 212. In this embodiment, the protruding distance of the pressing part 216 is 0.04mm. In other embodiments, the protruding distance of the pressing part 216 can be determined according to the processing accuracy. The sliding part 217 is connected to the side of the connecting body 215 facing the guide member 213, the sliding part 217 is slidably connected to the guide member 213, and the connecting body 215 is connected to the connecting plate 13 of the base 10 through the guide member 213.

[0060] In order to increase the heat insulation effect of the heat insulation sleeve 212 and prevent the heat insulation sleeve 212 from overheating and causing burns to the product 300, an annular groove 218 is provided on the circumferential side of the pressing portion 216. At this time, the pressing portion 216 is a stepped shaft with a small diameter in the middle and large diameters at both ends. The side surfaces of the two ends of the pressing portion 216 with larger diameters can be matched with the heat insulation sleeve 212 with high precision. In this way, by providing an annular groove 218 on the pressing portion 216, the contact area between the heat insulation sleeve 212 and the pressing portion 216 is reduced, thereby reducing the heat transfer efficiency, so that the heat insulation sleeve 212 will not overheat, thereby preventing the product 300 from being burned. In addition, a plurality of heat dissipation holes 219 arranged at intervals are provided on the heat insulation sleeve 212. The plurality of heat dissipation holes 219 can dissipate part of the heat into the air. The heat dissipation holes 219 are conducive to improving the heat dissipation efficiency of the heat insulation sleeve 212, and further preventing the heat insulation sleeve 212 from overheating and causing burns to the product 300.

[0061] The guide member 213 includes a guide block 2131 and a stop pin 2132. The guide block 2131 is connected to the connecting plate 13 of the base 10, and a guide hole 2133 is provided on the guide block 2131. The extension direction of the guide hole 2133 is the same as the extension direction of the elastic member 214. The shape of the guide hole 2133 can be a T-shaped slot or a dovetail slot. Correspondingly, the sliding portion 217 can be T-shaped or dovetail-shaped, and the sliding portion 217 is slidably connected in the guide hole 2133. In this way, by setting the guide hole 2133 as a T-shaped slot or a dovetail slot, the guide member 213 and the pressure head 211 can be clamped together, and the guide member 213 can accurately guide the pressure head 211.

[0062] The limiting pin 2132 is inserted into the bottom of the guide hole 2133 of the guide block 2131, and the extending direction of the limiting pin 2132 is perpendicular to the extending direction of the elastic member 214. The connecting body 215 of the pressing head 211 is provided with a waist-shaped hole 2151, and the waist-shaped hole 2151 passes through the sliding part 217. The extending direction of the waist-shaped hole 2151 is the same as the extending direction of the elastic member 214, and one end of the limiting pin 2132 is inserted into the waist-shaped hole 2151. In this way, by inserting the limiting pin 2132 into the waist-shaped hole 2151, the limiting pin 2132 limits the pressing head 211 to the guide member 213, so as to prevent the pressing head 211 from slipping off the guide member 213.

[0063] The heating assembly 22 includes a heating element 221 and a sensing element 222. The heating element 221 is a heating rod, which is inserted into the connector 215 of the pressure head 211, and is used to heat the pressure head 211. The sensing element 222 is a thermocouple, which is inserted into the connector 215 of the pressure head 211 and is spaced apart from the heating element 221, and is used to measure the temperature of the pressure head 211. When the temperature of the pressure head 211 is too high, the heating element 221 can stop heating the pressure head 211 to avoid the pressure head 211 from being too high; when the temperature of the pressure head 211 is too low, the heating element 221 continues to heat the pressure head 211.

[0064] The working process of the heat-insulating material pressing device 100 provided in the embodiment of the present application is roughly as follows:

[0065] Place the hot melt adhesive at the bottom of the groove 301, and then place the workpiece 200 on the hot melt adhesive. The heating element 221 heats the pressure head 211. When the temperature of the pressure head 211 reaches the use requirements, the cylinder drives the base 10 to move, and the base 10 drives the pressure head 211 and the heat insulation sleeve 212 to move toward the workpiece 200 and the product 300, and makes the pressure head 211 abut against the workpiece 200 and press the workpiece 200 against the product 300, and the heat insulation sleeve 212 abuts against the product 300. At this time, the pressure is maintained for a period of time so that the pressure head 211 heats the hot melt adhesive, so that the hot melt adhesive becomes sticky when heated, thereby bonding the workpiece 200 and the product 300 together. Among them, when the pressure head 211 presses the workpiece 200, the pressure head 211 slides along the guide member 213 and compresses the elastic member 214. The pressure head 211 elastically contacts the workpiece 200 under the elastic action of the elastic member 214.

[0066] During the hot pressing process of the heat-insulating pressing device 100, the pressing head 211 abuts against the workpiece 200 and transfers heat to the hot melt adhesive through the workpiece 200 to heat the hot melt adhesive, thereby achieving the purpose of bonding the workpiece 200 and the product 300 together. Since the pressing head 211 does not contact the product 300, it will not cause burns to the product 300. The heat-insulating sleeve 212 abuts against the product 300. On the one hand, the heat-insulating sleeve 212 plays a role of heat insulation to prevent burns to the product 300. On the other hand, the heat-insulating sleeve 212 limits the pressing head 211. When the heat-insulating sleeve 212 abuts against the product 300, the pressing head 211 stops pressing the workpiece 200. The heat-insulating sleeve 212 can prevent the pressing head 211 from causing overpressure to the workpiece 200. In addition, since the pressing head 211 elastically contacts the workpiece 200 under the elastic action of the elastic member 214, the workpiece 200 can be prevented from being crushed, thereby protecting the workpiece 200. During the sliding of the pressing head 211 , the guide member 213 guides the pressing head 211 , so that the sliding precision of the pressing head 211 is higher and no deviation occurs.
