[0022] The existing lamination machine currently available is through the resist pressure assembly 11 to press down the to be detected piece 2, the bottom of the to be detected piece 2 is easily blocked by the conveying channel, thus leading to the inaccurate image collected by vision, and the thickness of the to be detected piece 2 after being pressed cannot be completely obtained, therefore the lamination machine designed by the present application changes the way of pressing the to be detected piece 2, such as Figure 1As shown, the detection mechanism 1 includes a pressing assembly 11 and a visual assembly 12, the pressing assembly 11 includes a pressing part 111 and at least one set of lifting arms 112, the pressing part 111 is located above the detected part 2, the detected part 2 is composed of a plurality of core parts stacked on an end plate, the lifting arms 112 are used to provide a lifting force acting on the bottom of the detected part 2 to make the detected part 2 move away from the conveying mechanism, and contact with the pressing part 111, wherein the pressing part 111 is fixedly arranged, the lifting arms 112 include two ways to lift, the first way is arranged on the conveying mechanism 6, and the lifting arms 112 are driven by a power source to lift the detected part 2 upward, the second way is arranged on both sides of the conveying mechanism 6, and the lifting arms 112 have a gripper, and the second way is preferred in the utility model, specifically, the lifting arms 112 are two groups, the two groups of lifting arms 112 are oppositely arranged and form a containing space 113 for containing the detected part 2 between them, in the initial state, the two groups of lifting arms 112 are located on the conveying mechanism 6, at this time, the containing space 113 formed by the two groups of lifting arms 112 is aligned with the conveying direction of the conveying mechanism 6, and the detected part 2 is conveyed into the containing space 113 under the conveying of the conveying mechanism 6, that is, the bottom end plate contacts the bearing part of the lifting arms 112, and the lifting arms 112 move upward to move the detected part 2 upward for pressing, in addition, the direction of the conveying mechanism 6 conveying the detected part 2 is defined as the length direction, then the width side of the detected part 2 is horizontally perpendicular in the length direction, and the relative distance of the two groups of lifting arms 112 is the same as the width of the detected part 2, so that when the lifting arms 112 move upward and cooperate with the pressing part 111 for pressing, the stacked detected part 2 will be limited by the lifting arms 112, avoiding misalignment of the stacked detected part 2.

[0023] In order to avoid exposure, dark light and other influences when collecting images by vision, the detection mechanism 1 further includes a cover body for wrapping the pressing assembly 11 and the visual assembly 12.

[0024] The existing laminating machine (patent number: 2024108279011) discloses a stacking mechanism 3, the cam 32 in the stacking mechanism 3 is provided with a high-low sliding channel, and the positioning wheel slides in the sliding channel, when the cam 32 rotates, the positioning wheel slides in the sliding channel to move the stacking arm 31 in the vertical direction, and the sliding channel is easy to wear under long-time work, and the overall service life is low, therefore, the stacking mechanism 3 in the utility model also includes two stacking arms 31 and a cam 32, like Figure 2As shown, the cam 32 is located between the two stacked arms 31, and the first positioning wheel 33 is arranged on each of the two stacked arms 31. The cam 32 is provided with a high-low flange 34, and the first positioning wheel 33 is rollingly connected to the flange 34. The stacked arm 31 is further provided with an elastic member 35 (tension spring or compression spring), which is used to provide a force acting on the stacked arm 31 to make the first positioning wheel 33 tightly contact the flange 34. When the power source drives the cam 32 to rotate, the flange 34 on the cam 32 will drive the first positioning wheel 33 to roll on the flange 34, and drive the two stacked arms 31 to move up and down, thereby improving the service life of the cam 32.

[0025] In addition, in order to limit the movement direction of the stacked arm 31, the cam 32 further comprises a cam 32, and a column 36 is arranged between the cam 32 and the flange 34. The column 36 is sleeved with a sliding plate 37 for bearing the stacked arm 31. When the stacked arm 31 moves up and down, the sliding plate 37 slides along the length direction of the column 36 to limit the direction, and the stacked arm 31 is slidably connected to the sliding plate 37. The way of moving towards or away from each other of the stacked arm 31 is the same as the existing way, which is realized by rotating the cam 32.

[0026] Two spring members 38 are arranged between the two stacked arms 31, and the cam 32 is located between the two spring members 38.

[0027] The existing laminating machine (patent number: 2024108279011) discloses a feeding mechanism 4, and a limiting piece for blocking the material sheet is arranged in the material seat 41 in the feeding mechanism 4. However, the material taking hand cannot avoid grabbing multiple material pieces 5. Therefore, the feeding mechanism 4 designed in the utility model also comprises a storage assembly and a material seat 41. The material seat 41 is communicated with a material groove of the storage assembly, and the material seat 41 is provided with a blocking piece. Figure 3 As shown, the blocking piece is used to block the first material piece 5 above and the material piece 5 stacked below. Specifically, two insertion grooves are oppositely arranged in the material seat 41. The blocking piece comprises an insertion block 42 which is slidably connected in the insertion groove. An end of the insertion block 42 towards the material seat 41 is provided with a protruding portion 421 for inserting between the two material pieces 5 stacked. The protruding portion 421 is in a strip shape, and the thickness of the protruding portion 421 decreases from the end away from the material seat 41 to the end close to the material seat 41. When the material piece 5 stacked in the storage assembly is lifted upwards, the insertion block 42 is driven by the power source to retract into the insertion groove. When the gap between the first material piece 5 at the top and the second material piece 5 adjacent to the first material piece 5 is positioned to the protruding portion 421 of the insertion block 42, the power source drives the insertion block 42 to extend out of the insertion groove, so that the narrow end (the end with small thickness) of the protruding portion 421 is inserted into the gap to separate the first material piece 5 and the second material piece 5, thereby facilitating the material taking hand to take away the first material piece 5.
