Function: The third cylinder 501 can drive one of the assembly plates 2 to move left and right through the connecting block 502, while the other assembly plate 2 can remain stationary, while the second linear guide 101 and the first linear guide 503 facilitate the corresponding circuit board positioning mechanism 3, the circuit board support mechanism 4, and the circuit board fastening mechanism 5 to move left and right.

[0042] Specifically, a working opening 102 is provided on the workbench 1, and the working opening 102 is located below the two assembly plates 2. A suspension mechanism 6 is provided at the bottom of the slide 202, and the suspension mechanism 6 is located below the positioning column 301 and the support block 401, so that the suspension mechanism 6 can receive the circuit board 11 dropped from the slide 202; a bottom shell moving mechanism 7 is provided below the workbench 1, and the bottom shell moving mechanism 7 can move the bottom shell 12 to the bottom of the working opening 102.

Function: After the circuit board assembly formed by the two circuit boards buckled together loses support, it falls onto the suspension mechanism by gravity, and then the circuit board insertion mechanism descends to insert the circuit board assembly into the bottom shell.

[0043] Specifically, the suspension mechanism 6 includes two swing arms 601 distributed along the front and back, the tops of the two swing arms 601 are respectively rotatably arranged at the front and back ends of the bottom of the slide slot 202, the bottoms of the two swing arms 601 are respectively rotatably arranged with first deep groove ball bearings 602, the bottoms of the two swing arms 601 are connected with first springs 603, and the two first deep groove ball bearings 602 can receive the circuit board 11 dropped from the slide slot 202; when the circuit board insertion mechanism 8 presses down on the circuit board 11, the circuit board 11 can overcome the elastic tension of the first spring 603, so that the two first deep groove ball bearings 602 are separated from each other and the circuit board 11 can pass downward. Function: The first spring 603 pulls the two first deep groove ball bearings 602 through the two swing arms 601, overcomes the gravity of the circuit board assembly and supports the circuit board assembly, and prevents the circuit board assembly from falling into the bottom shell, so the force pressing down the circuit board 11 needs to overcome the tension of the first spring 603.

[0046] Specifically, a face shell fastening mechanism 9 is provided on one side of the workbench 1. The face shell fastening mechanism 9 includes a vertically extending fixed plate 901.

Function: The lower left and lower right limit support plates 906 approach each other under the elastic force of the second spring 910, and the lower left and lower right sides of the face shell are placed on the lower left and lower right limit support plates 906 respectively. Then, the upper left and upper right limit pressure plates 905 approach each other under the drive of the seventh drive cylinder 908, and move to the upper left and upper right sides of the face shell respectively, thereby limiting the upper and lower directions of the face shell.

[0048] Specifically, the facing sides of the lower left and lower right limiting support plates 906 are respectively provided with downwardly protruding surface shell release control blocks 911, and the bottom ends of the facing sides of the two surface shell release control blocks 911 are respectively provided with inclined surfaces 912; two second deep groove ball bearings 913 distributed along the left and right are rotatably arranged on the fixed plate 901, and the two second deep groove ball bearings 913 are respectively located below the two surface shell release control blocks 911, so that the two surface shell release control blocks 911 can respectively guide and cooperate with the two second deep groove ball bearings 913 downward to drive the lower left and lower right limiting support plates 906 away from each other; a vertically extending eighth driving cylinder 914 is provided on the side of the fixed plate 901 away from the sliding plate 903, and the eighth driving cylinder 914 is drivingly connected to the sliding plate 903, and the eighth driving cylinder 914 can drive the sliding plate 903 to move up and down.

[0051] In summary, the present invention positions and fastens two circuit boards through a cylinder, and the fastened circuit board assembly falls on the suspension mechanism by gravity, and the bottom shell moves to the bottom of the circuit board assembly through the cylinder, and the cylinder pushes the circuit board assembly into the bottom shell, and the cylinder drives the bottom shell and the circuit board assembly to move to the bottom of the surface shell, and the surface shell is pressed into the bottom shell by the cylinder. When the two circuit boards are fastened, a pressure sensor can be set to monitor and feedback the stress state so that it is within the allowable stress deformation range. Various sensors, alarms, etc. can also be set according to actual needs, which will not be listed here one by one.

[0052] Therefore, the present invention can control the movement of the cylinder through a program to automatically assemble the product circuit board and the product protective shell in a specified order. During the assembly process, the buckling status of the product can be monitored and feedback can be provided (such as by setting various laser sensors, etc.). The product assembly is completed by the mutual buckling of the elastic buckles between the product components. The assembly of this equipment is more stable than the traditional manual assembly method, and the detection feedback is reliable, free and flexible, eliminating the risks of electrostatic damage, inadequate buckling, collision, wrong parts, and excessive stress. The equipment automatically buckles, has high production efficiency, low worker fatigue, small size, and saves space.
