[0028] When the worker needs to hot-press the mobile phone protective cover and the cover plate together, first, the mobile phone protective cover and the cover plate can be aligned and placed together in the middle of the placement table 4, during which the mobile phone protective cover will first contact and press the four surrounding limiting plates 5, so that the corresponding four limiting plates 5 are all moved away, and the first spring 51 is compressed, so that the limiting plate 5 can clamp and fix the mobile phone protective cover under the action of the first spring 51, and then the sliding plate 3, the placement table 4 and the mobile phone protective cover are moved to the right by the electric sliding rail 2 until the mobile phone protective cover and the cover plate are located directly below the pressing plate 7, and under normal circumstances, the partition plate 10, the baffle 11 and the shell 1 will combine to form a relatively closed space, and when the sliding plate 3 moves to the right until it contacts and presses the baffle 11, the baffle 11 will also move to the right with the sliding plate 3, and the second spring 111 is compressed, and at this time, the protruding part on the left side of the sliding plate 3 cooperates with the partition plate 10 and the shell 1 to form a relatively closed space, so as to avoid the situation that the pressing plate 7 and the heating plate 71 are affected by the external environment and the heat distribution is uneven, and then the heating plate 71 can be started, and the connecting frame 61, the heating plate 71 and the pressing plate 7 are moved downward by the electric guide rail 6, so that the mobile phone protective cover and the cover plate are hot-pressed and bonded together, after hot-pressing, first, the connecting frame 61, the heating plate 71 and the pressing plate 7 are moved upward by the electric guide rail 6 to reset, and then the sliding plate 3, the placement table 4 and the mobile phone protective cover are moved to the left by the electric sliding rail 2 to reset, and the baffle 11 also moves to the left to reset under the action of the second spring 111, and during this period, the hot-pressed mobile phone protective cover and cover plate can also be quickly cooled by the fan 14 to avoid workers being scalded when taking the mobile phone protective cover, and then the top plate 9 can be moved upward by the electric push rod 8 to push the mobile phone protective cover upward, so as to facilitate the worker to take it, and at this time, the corresponding four limiting plates 5 will move to the reset position under the action of the first spring 51, and after the mobile phone protective cover is pushed out, the top plate 9 can be moved downward by the electric push rod 8 to reset.
[0029] Example 2
[0030] Based on example 1, as shown in Figure 5 It also includes a backing plate 12, a third spring 121 and a guide block 13, the left and right sides of the pressing plate 7 are fixedly connected with front and back symmetrically distributed guide blocks 13, and the four guide blocks 13 are slidably connected with the backing plate 12, and the third spring 121 is fixedly connected between the backing plate 12 and the guide block 13.
[0031] As shown in Figure 5 The backing plate 12 is made of Teflon material.
[0032] When the electric guide rail 6 drives the connecting frame 61, the heating plate 71 and the pressing plate 7 to move downwards, the backing plate 12 also moves downwards and first contacts the mobile phone protective sleeve and the cover plate, at this time the heating plate 71 and the pressing plate 7 continue to move downwards and contact the backing plate 12 under the action of the electric guide rail 6, the third spring 121 is compressed immediately, so that the backing plate 12 exists between the pressing plate 7 and the cover plate during hot pressing, thereby buffering the heat transfer of the backing plate 12, making the cover plate heated more evenly, avoiding the phenomenon of sticking due to local overheating, when the electric guide rail 6 drives the connecting frame 61, the heating plate 71 and the pressing plate 7 to move upwards and reset, the third spring 121 first gradually restores to the original state, and then drives the backing plate 12 to move upwards and reset.
