The terminology used in the specification of the present application herein is only for the purpose of describing specific embodiments and is not intended to limit the present application.

[0032] Please refer to Figures 1 to 6 , the raw leather rear cover hot pressing equipment of an embodiment of the present application, including transfer assembly 10, jig 20 detachably mounted on transfer assembly 10, and hot pressing assembly 30 mounted on the top of transfer assembly 10; hot pressing assembly 30 is used to correspond to jig 20, and jig 20 is used to carry the raw leather layer and the plastic layer to be hot pressed.

[0033] The transfer assembly 10 comprises a machine body 11, a top plate 12 installed on the top of the machine body 11, a transfer plate 13 slidingly connected to the opposite sides of the top surface of the top plate 12, and a push-pull air cylinder 14 installed on the opposite sides of the bottom surface of the top plate 12; the push-pull air cylinder 14 is connected to the transfer plate 13 through an adapter block 15 penetrating the top plate 12 upward, so that the push-pull air cylinder 14 is connected to the transfer plate 13, and then the transfer plate 13 can be driven to slide.

[0034] Specifically, two sliding grooves 120 are provided on the top plate 12 in an interval, and the sliding grooves 120 correspond to the transfer plate 13 one by one. Among them, the adapter block 15 is connected to the transfer plate 13 upward after penetrating the sliding groove 120; the transfer plate 13 is used to carry the connecting jig 20.

[0035] In this embodiment, as shown in Figure 3 and Figure 4 , the transfer plate 13 is arranged in a rectangular shape, and the opposite sides of the top surface of the transfer plate 13 are respectively provided with positioning pins 130, which are symmetrically arranged about the center of the transfer plate 13 by 180 degrees, and the positioning pins 130 are used to position the connecting jig 20.

[0036] The jig 20 comprises a jig body 21 for connecting the transfer plate 13, a limiting block 22 installed on the top surface of the jig body 21 at opposite corners, and a handle 23 connected to the opposite ends of the top surface of the jig body 21. The top surface of the jig body 21 is provided with a receiving recess 24 for positioning and placing the leather layer and the plastic layer. Among them, the limiting block 22 is arranged around the receiving recess 24, which effectively improves the positioning accuracy of hot pressing.

[0037] The opposite ends of the top surface of the jig body 21 are respectively provided with avoiding holes 25 corresponding to the receiving recess 24, which provides sufficient operation space for fingers, and facilitates workers to quickly and accurately place or take out the leather layer and the plastic layer. Among them, the avoiding holes 25 are arranged adjacent to the handle 23.

[0038] Further, in this embodiment, the opposite sides of the jig body 21 are respectively provided with positioning holes 26, which are symmetrically arranged about the center of the jig body 21 by 180 degrees, and the positioning holes 26 correspond to the positioning pins 130 one by one, realizing the quick butt joint between the jig 20 and the transfer plate 13. In addition, combined with the design of the handle 23, the operator can conveniently and quickly replace different jigs 20, which simplifies the replacement process, effectively reduces the time consumption, improves the replacement efficiency, ensures the production progress.

[0039] The hot-pressing assembly 30 comprises a support 31 mounted above the top plate 12, heat insulation plates 32 connected to opposite sides of the inside of the support 31, hot-pressing mold plates 33 respectively mounted on the bottom surfaces of the heat insulation plates 32, alignment pieces 34 fixedly connected to one end of the heat insulation plates 32, and lifting cylinders 35 mounted on opposite sides of the top surface of the support 31; the piston rods of the lifting cylinders 35 pass through the support 31 and are connected to the heat insulation plates 32 downward to drive the heat insulation plates 32 and the hot-pressing mold plates 33 to move up and down. A pressure sensor 36 is further clamped between the piston rod of the lifting cylinder 35 and the heat insulation plate 32, as shown in Figure 2

[0040] Specifically, the bottom end of the alignment piece 34 protrudes beyond the top surface of the hot-pressing mold plate 33, and the alignment piece 34 is used to be inserted into the avoiding hole 25.

If the jig 20 and the hot-pressing mold plate 33 are misaligned, the alignment piece 34 will not be correctly inserted into the avoiding hole 25, at this time, the pressure value detected by the pressure sensor 36 will exceed the preset threshold value, and the system will stop the work of the lifting cylinder 35 to prevent damage caused by continuous pressing, thereby greatly improving the reliability and safety of the hot-pressing process.

[0041] In the embodiment, a plurality of electric heating bodies 330 are mounted in the hot-pressing mold plate 33.

[0042] In the embodiment, guide rods 37 are respectively connected to opposite sides of the top surface of the heat insulation plate 32, the guide rods 37 slide through the top of the support 31 to ensure the stability of the lifting of the heat insulation plate 32. The top end of the guide rod 37 is further connected to a limiting ring 38, the limiting ring 38 is located above the support 31, and is used to limit the maximum downward movement distance of the heat insulation plate 32 to prevent damage to the substrate layer and the plastic layer caused by excessive downward pressing.

[0043] The substrate rear cover hot-pressing equipment has the advantages of simple structure and convenient use. The alignment piece 34 is inserted into the avoiding hole 25, and the real-time detection of the pressure sensor 36 can ensure the accurate alignment of the jig 20 and the hot-pressing mold plate 33, effectively avoiding damage caused by inaccurate alignment, and greatly improving the reliability and safety of the hot-pressing process.
