[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] In the description of the present invention, it should be understood that terms such as "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0029] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, this embodiment includes a side panel assembly component 100 and a working frame 200. The side panel assembly component 100 is arranged on the working frame 200. The side panel assembly component 100 includes a side panel clamp 101 and a posture control component 102. The side panel clamp 101 is rotatably connected to the working frame 200. The posture control component 102 is configured to control the verticality of the side panel clamp 101. The posture control component 102 includes an upper telescopic cylinder 108 and a lower telescopic cylinder 109. The upper telescopic cylinder 108 is internally connected to the lower telescopic cylinder 109, and the upper telescopic cylinder 108 and the lower telescopic cylinder 109 are symmetrically arranged on both sides of the rotation axis of the side panel clamp 101. The piston rods of the upper telescopic cylinder 108 and the lower telescopic cylinder 109 are both connected to the side panel clamp 101, and the connection points of the piston rod of the lower telescopic cylinder 109 and the side panel clamp 101 and the connection points of the piston rod of the upper telescopic cylinder 108 and the side panel clamp 101 are symmetrically distributed on both sides of the rotation axis of the side panel clamp 101.

[0030] In this embodiment, the side panel fixture 101 of this embodiment is used to grab the side panel, and the side panel fixture 101 rotates on the working frame 200. When the side panel fixture 101 rotates, the horizontally placed side panel can be grabbed. The posture control component 102 is used to control the verticality of the side panel fixture 101 and thus control the verticality of the side panel. The upper telescopic cylinder 108 and the lower telescopic cylinder 109 are respectively arranged on both sides of the rotating shaft of the side panel fixture 101. When the pressure in the upper telescopic cylinder 108 and the lower telescopic cylinder 109 are equal, the upper telescopic cylinder 108 and the lower telescopic cylinder The pressure applied by 109 to the side panel clamp 101 is also equal, and the distances from the contact points of the upper telescopic cylinder 108 and the lower telescopic cylinder 109 with the side panel clamp 101 to the rotation axis of the side panel clamp 101 are equal, so the torque generated by the upper telescopic cylinder 108 and the lower telescopic cylinder 109 on the side panel clamp 101 is equal; when the rotation axis of the side panel clamp 101 is parallel to the horizontal plane, the same torque is applied on both sides of the rotation axis of the side panel clamp 101, so that the side panel clamp 101 can maintain a vertical state, thereby controlling the verticality of the side panel clamp 101.

[0031] The pressure in the upper telescopic cylinder 108 and the lower telescopic cylinder 109 in this embodiment is adjustable. When the pressure in the upper telescopic cylinder 108 is higher, the side panel clamp 101 will rotate downward. When the pressure in the lower telescopic cylinder 109 is higher, the side panel clamp 101 will rotate upward. When the pressure in the upper telescopic cylinder 108 and the lower telescopic cylinder 109 are equal, the side panel clamp 101 will remain in a vertical state. The posture of the side panel clamp 101 is controlled by the pressure of the upper telescopic cylinder 108 and the lower telescopic cylinder 109, so that the side panel clamp 101 can be rotated to grab the side panel, while maintaining the verticality of the side panel clamp 101 to achieve alignment between the side panel and the bottom panel.

[0032] When this embodiment is in use, the pressure in the upper telescopic cylinder 108 is first controlled to be greater than the lower telescopic cylinder 109. At this time, the torque applied by the upper telescopic cylinder 108 to the side panel clamp 101 is greater than the torque applied by the lower telescopic cylinder 109 to the side panel clamp 101. Therefore, the side panel clamp 101 rotates downward, and when the side panel clamp 101 is close to the horizontally placed side panel, the side panel is grabbed, and then the upper telescopic cylinder 108 and the lower telescopic cylinder 109 are connected. The pressure of the lower telescopic cylinder 109 gradually increases to the same level as the pressure of the upper telescopic cylinder 108. In this process, the side panel clamp 101 gradually rotates to a vertical position, and at the same time, the side panel clamp 101 drives the side panel to rotate to a vertical position. Since the upper telescopic cylinder 108 and the lower telescopic cylinder 109 are internally connected, the vertical posture of the side panel clamp 101 can be maintained, thereby maintaining the verticality of the side panel.

[0033] like Figure 7 and Figure 8 As shown, the side panel clamp 101 of this embodiment is provided with an upper slide 104 and a lower slide 105, and the upper slide 104 and the lower slide 105 are symmetrically arranged on both sides of the rotation axis of the side panel clamp 101, the piston rod of the upper telescopic cylinder 108 is provided with an upper slider 111, and the piston rod of the lower telescopic cylinder 109 is provided with a lower slider 112, the upper slider 111 is slidably connected to the upper slide 104, and the lower slider 112 is slidably connected to the lower slide 105.

[0034] In this embodiment, while the upper telescopic cylinder 108 and the lower telescopic cylinder 109 maintain a fixed position, the piston rods are extended and retracted to drive the movement of the upper slider 111 and the lower slider 112. The upper slider 111 slides in the upper slide 104, and the lower slider 112 slides in the lower slide 105, thereby allowing the side panel clamp 101 to rotate. The upper slide 104 and the lower slide 105 are used to limit the position of the movement of the upper slider 111 and the lower slider 112, ensuring that the torque applied by the upper slider 111 and the lower slider 112 to the posture control component 102 is not offset, thereby improving the stability of the side panel clamp 101.

[0035] like Figure 7 As shown, the posture control assembly 102 of this embodiment also includes a vertical bracket 107, and the upper telescopic cylinder 108 and the lower telescopic cylinder 109 are fixedly arranged on the vertical bracket 107. The vertical bracket 107 is perpendicular to the horizontal plane. A direction-changing valve 110 is provided on the vertical bracket 107. The upper telescopic cylinder 108 and the lower telescopic cylinder 109 are respectively connected to the direction-changing valve 110. The direction-changing valve 110 is configured to control the telescopic state of the piston rods of the upper telescopic cylinder 108 and the lower telescopic cylinder 109.

[0036] When the upper and lower telescopic cylinders 108 and 109 are in the same position, the upper and lower telescopic cylinders 108 and 109 are in the same position.

[0037] like Figure 3 、 Figure 8 and Figure 9 As shown, the working frame 200 in this embodiment is provided with a lifting bracket 201 and a lifting slot 202, the lifting bracket 201 is provided with a clamp shaft 203, the side panel clamp 101 is provided with a rotating base 103, the rotating base 103 is rotatably connected to the clamp shaft 203, the vertical bracket 107 is provided in the lifting slot 202, the vertical bracket 107 slides up and down in the vertical direction in the lifting slot 202, the lifting bracket 201 is slidably connected to the working frame 200, the lifting bracket 201 slides up and down in the vertical direction on the working frame 200, and the vertical bracket 107 and the lifting bracket 201 are synchronously lifted and lowered in the vertical direction.

[0038] In this embodiment, the side panel clamp 101 is set on the lifting bracket 201 through the clamp shaft 203. When the lifting bracket 201 is lifted or lowered relative to the working frame 200, the side panel clamp 101 is driven to lift or lower synchronously. The vertical bracket 107 is set in the lifting slot 202. When the lifting bracket 201 is lifted or lowered on the working frame 200, the vertical bracket 107 is lifted or lowered synchronously, thereby ensuring that the relative positions of the upper telescopic cylinder 108, the lower telescopic cylinder 109 and the clamp shaft 203 remain unchanged.

[0039] In this embodiment, when grabbing the side panel, the height of the side panel clamp 101 can be lowered by the lifting bracket 201, so that the side panel clamp 101 is close to the horizontally placed side panel, which makes it easier for the side panel clamp 101 to grab the side panel.

[0040] At the same time, the height positions of the side panel fixture 101 and the posture control component 102 can be adjusted according to the size of the side panel, and are suitable for side panels of larger sizes.

[0041] like Figure 9As shown, the clamp shaft 203 in this embodiment is provided with a shaft shoulder 204, and the rotating base 103 is engaged in the shaft shoulder 204. The shaft shoulder 204 limits the sliding of the rotating base 103 on the clamp shaft 203. By setting the shaft shoulder 204 on the clamp shaft 203, the rotating base 103 rotates in the shaft shoulder 204, avoiding axial displacement of the rotating base 103 on the clamp shaft 203, thereby keeping the position of the side plate clamp 101 unchanged and ensuring the alignment of the side plate and the bottom plate.

[0042] like Figure 1 and Figure 3 As shown, this embodiment also includes a servo conveying device 300, and the servo conveying device 300 is arranged on the working frame 200.

The sliding direction of the conveying component 301 is perpendicular to the conveying direction of the conveying component 301. The translation component 302 is configured to push the conveying component 301.

[0043] In this embodiment, a conveying component 301 and a translation component 302 are also provided. The conveying component 301 can be used to convey the side panels and the bottom panel, and the translation component 302 can be used to adjust the distance between the conveying component 301 and the side panel assembly component 100. When using this embodiment, the side panels and the bottom panel are first placed on the conveying component 301 in sequence, and the conveying component 301 conveys the side panels to the corresponding positions of the side panel fixtures 101. After the side panel fixtures 101 grab the side panels, the conveying component 301 conveys the bottom panel to the corresponding positions of the side panel fixtures 101. At this time, the translation component 302 adjusts the distance between the conveying component 301 and the side panel assembly component 100, and then adjusts the distance between the bottom panel and the side panel, thereby realizing automatic grabbing of the side panels and automatic alignment of the side panels and the bottom panel, while ensuring the verticality and alignment of the side panels, improving production efficiency, reducing the labor intensity of workers, and ensuring the structural strength of the finished product.

[0045] In this embodiment, the side plates and bottom plates are transported by the cooperation of the conveyor belt 303 and the conveyor roller 304. Multiple sets of side plates and bottom plates can be placed to achieve continuous transportation of plates. At the same time, the length can be flexibly adjusted according to the production line.
