[0036] like Figure 1 As shown, it is a mobile phone shell skinning machine 100 shown in the present invention, which is used to stick a leather case 200 on a mobile phone shell frame 300.

[0037] like Figure 1 As shown, the mobile phone shell skinning machine 100 includes: a fixed mold 10, a loading platform 20, a push mechanism 30, a hot melt mechanism 40 and a movable mold, wherein the fixed mold 10 is used to install the loading platform 20, the loading platform 20 is used to place the leather case 200 and the mobile phone shell frame 300, and guide the leather case 200 toward the hot melt mechanism 40, the push mechanism 30 is used to push the leather case 200 toward the hot melt mechanism 40 to bend toward the middle, the hot melt mechanism 40 is connected to the movable mold, and is used to be inserted into the loading platform 20, and the movable mold is used to The hot melt mechanism 40 is driven to push the leather case 200 bent toward the middle, so that the leather case 200 bent toward the middle is flipped around the side of the mobile phone shell frame 300 to the inside of the mobile phone shell frame 300, and the leather case 200 is controlled to be connected to the inner wall of the mobile phone shell frame 300 by hot melting, so as to realize automatic control of the leather case 200 to fold inward along the side of the mobile phone shell frame 300, thereby stably controlling the folding efficiency of the leather case 200, and achieving the purpose of quantifying the production efficiency of the leather case 200 mobile phone case.

[0038] Below, combined Figures 1 to 4 , the above-mentioned mobile phone shell skinning machine 100 is further explained.

[0039] like Figure 1 to Figure 2 As shown, the fixed mold 10 is connected to the loading platform 20 and is provided with a mounting groove 11. The loading platform 20 is installed in the mounting groove 11. The mounting groove 11 is used to improve the installation accuracy of the loading platform 20, so as to increase the processing accuracy of the mobile phone shell.

[0040] like Figure 2As shown, the loading platform 20 is rectangular in shape, and is provided with a loading groove 21, and has a bending area 22 and an inverting area 23 corresponding to the loading groove 21, and the bending area 22 is arranged around the inverting area 23. When in use, the leather case 200 and the mobile phone shell frame 300 are placed in the loading groove 21 in sequence, and the mobile phone shell frame 300 and the loading groove 21 are used to squeeze the leather case 200, so that the leather case 200 is bent under the guidance of the inner wall of the loading groove 21, and extends to the bending area 22 for being pushed by the edge pushing mechanism 30, wherein the width of the bending area 22 is greater than the thickness of the leather case 200, and the width of the bending area 22 is less than the sum of the thickness of the leather case 200 and the thickness of the side of the mobile phone shell frame.

[0041] like Figure 1 to Figure 2 As shown, there are multiple edge pushing mechanisms 30, each of which is arranged around the loading platform 20, and each of which includes an edge pushing driving member 31 and a guide member 32. The edge pushing driving member 31 is a cylinder, and the edge pushing driving member 31 is used to drive the guide member 32 to move toward the bending area 22 and cover the bending area 22, so as to push the holster 200 at the bending area 22 to the inverting area 23.

[0042] In order to prevent the edge guide 32 from entering the inner turning area 23 and interfering with the operation of the hot melt mechanism 40, Figures 2 to 3 As shown, the edge guide member 32 includes an adapter block 321 and a contact block 322. The adapter block 321 is connected to the edge pushing drive member 31. When the contact block 322 extends to the bending zone 22, the adapter block 321 contacts the loading platform 20 to control the movement accuracy of the contact block 322 through the adapter block 321, so that the edge guide member 32 can effectively control and cover the bending zone 22, thereby preventing the contact block 322 from entering the inverting zone 23 and interfering with the operation of the hot melt mechanism 40.

[0043] In order to improve the production yield of leather case 200 mobile phone case, Figure 4 As shown, the contact block 322 is provided with a guide surface 323, which is arranged on a side of the contact block 322 close to the material loading groove 21 and is arranged in an arc shape. The guide surface 323 can effectively prevent the contact block 322 from damaging the leather case 200 during the process of pushing the leather case 200, thereby achieving the purpose of improving the production yield of the leather case 200 mobile phone case.

[0044] To avoid the situation where the hot melt mechanism 40 cannot be inserted into the mounting groove 11 of the loading platform 20, as shown in FIG. Figure 4As shown, the contact block 322 is provided with a guide surface 324, and the guide surface 324 is provided on a side of the contact block 322 close to the movable mold, and the automatic mold is inclined in the direction of the material loading groove 21. When the hot melt mechanism 40 is inserted into the loading platform 20, if the hot melt mechanism 40 is offset to the bending area 22, the guide surface 324 of the contact block 322 can guide the hot melt mechanism 40 to move to the inverted area 23 and insert it into the mounting groove 11 of the loading platform 20, thereby avoiding the hot melt mechanism 40 from abutting against the contact block 322, resulting in the hot melt mechanism 40 being unable to be inserted into the mounting groove 11 of the loading platform 20.

[0045] like Figure 2 As shown, the hot melt mechanism 40 is installed on the movable mold and is arranged corresponding to the position of the inverted area 23. Specifically, the hot melt mechanism 40 includes a hot melt component 41 and a pressing edge assembly 42. The hot melt component 41 is arranged around the pressing edge assembly 42. The pressing edge assembly 42 protrudes from a side of the hot melt component 41 close to the loading platform 20, and is used to contact the leather case 200 and squeeze the leather case 200, so that the leather case 200 is flipped around the side wall of the mobile phone shell frame 300 into the mobile phone shell frame.

[0046] like Figure 2 As shown, the edge clamping assembly 42 includes an edge clamping block 421, a limiting member 422 and an elastic member 423. The edge clamping block 421 protrudes from a side of the hot melt member 41 close to the loading platform 20 and is connected to the limiting member 422. The limiting member 422 is slidably connected to the movable mold. The elastic member 423 is used to provide elastic force for the edge clamping block 421 to approach the loading platform 20. The limiting member 422 includes a guide rod 424 and a limiting portion 425. The guide rod 424 passes through the movable mold and is connected to the edge clamping block 421. The limiting portion 425 is arranged at one end of the guide rod 424 away from the edge clamping block 421. The elastic member 423 is sleeved on the guide rod 424. The movable mold is provided with a slide groove 511. The edge clamping block 421 is slidably connected to the slide groove 511 to improve the sliding accuracy of the edge clamping block 421.

[0047] like Figure 2 As shown, the movable mold is used to drive the hot melt mechanism 40 to pass through the inverted area 23 and insert into the material trough 21. The movable mold includes an upper mold plate 51 and a movable mold driving component (not shown). The upper mold plate 51 is provided with a slide groove 511. The movable mold driving component is a hydraulic cylinder, which is used to drive the upper mold plate 51 to approach or move away from the fixed mold 10.

[0048] When the mobile phone shell skinning machine 100 shown in the present invention is used, Figure 2As shown, the leather case 200 and the mobile phone shell frame 300 are placed in the material placement groove 21 of the loading platform 20, and the leather case 200 is squeezed by the cooperation between the material placement groove 21 and the mobile phone shell frame 300, so that the leather case 200 is located in the bending area 22 under the guidance of the inner wall of the material placement groove 21, and the edge pushing driving member 31 of each edge pushing mechanism 30 is started, and the edge guide member 32 is driven by the edge pushing driving member 31 to move toward the bending area 22 until the adapter block 321 of the edge guide member 32 contacts the loading platform 20. At this time, as shown in FIG. Figure 3 As shown, the contact block 322 of the guide member 32 covers the bending area 22 to push the leather case 200 at the bending area 22 to the inverted area 23, the movable mold driving member of the movable mold drives the upper mold plate 51 to approach the fixed mold 10, and the edge pressing block 421 of the edge pressing assembly 42 of the hot melt mechanism 40 first contacts the leather case 200 at the inverted area 23, squeezes the leather case 200 at the inverted area 23, and makes the leather case 200 at the inverted area 23 flip around the side wall of the mobile phone shell frame 300 until the leather case 200 contacts the hot melt member 41 of the hot melt mechanism 40, and finally, when the hot melt member 41 pushes the leather case 200 to contact the inner wall of the mobile phone shell frame 300, the hot melt member 41 is started to hot-melt the leather case 200 on the inner wall of the mobile phone shell frame 300, so as to achieve the leather case 200 being attached to the mobile phone shell frame 300.

[0049] The mobile phone shell skinning machine 100 provided in the present application has the beneficial effects of: the material loading groove 21 of the loading platform 20 is used to place the mobile phone shell frame 300 and the leather case 200, the edge pushing driving member 31 of the edge pushing mechanism 30 drives the guide member 32 to cover the bending area 22, and the movable mold drives the hot melt mechanism 40 to insert into the material loading groove 21 through the inverting area 23, which is conducive to pushing the leather case 200 at the bending area 22 to the inverting area 23 through the guide member 32, so that the hot melt mechanism 40 pushes the leather case 200 at the inverting area 23 into the mobile phone shell frame 300, and controls the leather case 200 to be connected to the inner wall of the mobile phone shell frame 300 by hot melting, so as to realize automatic control of the leather case 200 to be folded inwardly along the side of the mobile phone shell frame 300, thereby stably controlling the folding efficiency of the leather case 200, and achieving the purpose of quantifying the production efficiency of the leather case 200 mobile phone case.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent.
