the conveying mechanism 100 is mainly used for conveying plates, wherein three independent conveying belts 101 are provided, mainly because a top plate and a bottom plate are positioned in the middle, and side plates are positioned on two sides, the independent conveying belt 101 at the moment is divided into a side part and a middle part, the independent conveying belt 101 at the middle is respectively provided with a bottom plate clamping assembly 300a and an end plate clamping assembly 300c, the bottom plate clamping assembly 300a and the end plate clamping assembly 300c are distributed front and back, at the moment, the independent conveying belt 101 drives the side plate clamping assembly 300b, the end plate clamping assembly 300c and the bottom plate clamping assembly 300a to move, so that the side plate clamping assembly 300b, the end plate clamping assembly 300c and the bottom plate clamping assembly 300a can rotate from bottom to top, and the plates are flatly laid at the temporary storage mechanism 103 according to the distribution sequence, when the side plate clamping assembly 300b, the end plate clamping assembly 300c and the bottom plate clamping assembly 300a are positioned at the bottom, the side plate clamping assembly 300b, the end plate clamping assembly 300c and the bottom plate clamping assembly 300a clamp corresponding plates, the clamped side plates 300b, the clamping assembly 300c and the bottom plate clamping assembly 300a move from top along with the independent conveying belt 101, and the side plate clamping assembly 300a conveniently rotates from bottom plate 300a to the bottom plate clamping assembly 300 b;
the independent conveyor belt 101 on the side is provided with an adjusting block 102, and the position of the adjusting block 102 close to the conveying end of the conveyor belt is provided with a guide slope 1021 for turning the sliding side plate clamping assembly 300b by ninety degrees at the adjusting block 102;
at the moment, the adjusting block 102 is installed on the installation frame of the independent conveying belt 101 on the side face, the adjusting block 102 cannot influence the operation of the belt body of the independent conveying belt 101, the adjusting block 102 occupies the surface space of the independent conveying belt 101, the guide slope 1021 passes through the side plate clamping assembly 300b, the side plate clamping assembly 300b is influenced by the guide of the guide slope 1021, the side plate clamping assembly 300b slides to the plane area of the adjusting block 102, the included angle between the clamping face of the side plate clamping assembly 300b and the horizontal plane is 90 degrees, deformation is completed, in the process, an auxiliary power structure is not needed to be used, the side plate clamping assembly 300b is turned over and deformed under the power action of the independent conveying belt 101, the angle of the side plate is matched with the bottom plate, and preparation is made for subsequent fitting;
the tight attaching assembly 200 comprises an alignment pushing mechanism 201 installed on the side face of the independent conveying belt 101 and alignment blocking mechanisms 202 rotating on two sides of the middle independent conveying belt 101, the alignment pushing mechanism 201 is used for pushing the side plate clamping assembly 300b to approach to the bottom plate clamping assembly 300a and the end plate clamping assembly 300c to attach the plate body, and the alignment blocking mechanisms 202 are used for pushing the end plate clamping assembly 300c to overturn and simultaneously displace to one side close to the bottom plate clamping assembly 300a to attach the plate body;
because the above has explained the turnover principle of the side plate clamping assembly 300b, but because the side plate clamping assembly 300b has allowance for turnover, after the side plate clamping assembly 300b is turned over, the side plate still cannot be attached to the bottom plate, so the side plate clamping assembly needs to be realized by the aid of the alignment pushing mechanism 201, firstly, after the side plate clamping assembly 300b is turned over to be vertical to 90 degrees, the alignment pushing mechanism 201 applies horizontal acting force, at this time, the side plate clamping assembly 300b slides to the bottom plate clamping assembly 300a, after sliding, the side plate clamping assembly 300b contacts the vertical side plate to the bottom plate to be attached, and meanwhile, the alignment pushing mechanism 201 can increase the force application effect from the side plate and the bottom plate, so that the attachment is realized in this state for subsequent welding;
