[0002] The processing steps of traditional wooden mortise and tenon structure products are cutting, sawing tenons, chiseling tenons, fine trimming and assembling. First, cut the stainless steel plate into four rectangular plates that are pairwise the same and a stainless steel bottom plate. Then, cut symmetric mortise grooves and tenons on both sides of the rectangular plates, and chisel an installation groove on the inner side of the bottom of the rectangular plates. During the assembly process, first insert three rectangular plates together to form a "C" shape, and the installation grooves on the three rectangular plates are also connected. Then, insert the stainless steel bottom plate into the installation groove, and insert the last rectangular plate at the opening of the "C" shape to complete the assembly. Thus, the four rectangular plates enclose the side of the water tank, and the stainless steel bottom plate serves as the bottom of the water tank.

[0025] Before the workbench reaches the calibration area, the data measured by the laser rangefinder is recorded as M0, where M0 is the length of the side L2 of the workbench;

[0026] When the workbench drives the first stainless-steel plate to move upward and reaches the measurement range of Laser Rangefinder 1, the data measured by Laser Rangefinder 1 is recorded as M1. Stop moving the workbench. M1 is the distance from Laser Rangefinder 1 to area A on the side wall of the first stainless-steel plate. If M1 < M0, continue to run. If M1 ≥ M0, the first placed stainless-steel plate is unqualified;

[0027] The hydraulic cylinder 2 inside the machine body drives Laser Rangefinder 1 to move horizontally. Laser Rangefinder 1 moves away from edge L2. The moving position of Laser Rangefinder 1 will record position data through the scale axis. The measured data is successively recorded as {M1, M1…M1}, {M2, M2…M2}, and {M3, M4, M3, M4…M3, M4}; among them, M2 represents the data measured when the light emitted by Laser Rangefinder 1 passes through the installation slot. If M2 = M0, continue to run. If M1 ≠ M0, the first placed stainless-steel plate is unqualified;

[0030] Mark the position data {M 21 , M 22 …M 23} corresponding to the data {M2, M2…M2} on the measuring axis. The moving position of the first loading plate will also record position data through the scale axis. The starting points of the scale axes used by the first loading plate and Laser Rangefinder 1 are the same; The electric push rod inside the support plate drives the first slider to move. The first slider drives the first loading plate to move to position M 23 . The external robotic arm places the stainless-steel bottom plate between the first loading plate and the second loading plate. The electric push rod inside the first slider drives the second loading plate to approach the first loading plate, thereby clamping the stainless-steel bottom plate. The opposite surfaces of the first loading plate and the second loading plate are respectively in contact with the two side walls of the installation slot, so that the position of the stainless-steel bottom plate and the installation slot is aligned horizontally;

[0031] The workbench continues to move upward, and the height of the light-emitting center of the second laser rangefinder from the bottom surface of the first loading port is set to h. The data measured by the second laser rangefinder are recorded as {Z1, Z1…Z1}, {Z2, Z2…Z2} and {Z3} in sequence. When the data is collected to a {Z3}, the workbench stops moving;

Stop moving the workbench. M1 is the distance from the first laser rangefinder to area A on the side wall of the first stainless steel plate. If M1 < M0, continue to run. If M1 ≥ M0, the first placed stainless steel plate is unqualified;

[0040] The hydraulic cylinder two in the machine body drives the first laser rangefinder to move horizontally. The first laser rangefinder moves away from side L2. The moving position of the first laser rangefinder will record position data through the scale axis. The measured data are successively recorded as {M1, M1…M1}, {M2, M2…M2}, and {M3, M4, M3, M4…M3, M4}; among them, M2 represents the data measured when the light emitted by the first laser rangefinder passes through the installation slot. If M2 = M0, continue to run. If M1 ≠ M0, the first placed stainless steel plate is unqualified;

[0041] M3 and M4 represent the mortise and tenon joints where the side walls of the stainless steel plate are arranged in a cycle. If M3 ≠ M4 and several M3 and M4 are arranged in a cycle, continue to run; if M3 = M4 and several M3 and M4 are arranged in a cycle, the first placed stainless steel plate is unqualified; if M3 ≠ M4 and several M3 and M4 are not arranged in a cycle, the first placed stainless steel plate is unqualified; if M3 = M4 and several M3 and M4 are not arranged in a cycle, the first placed stainless steel plate is unqualified;

[0042] If the monitoring result shows that the first placed stainless steel plate is unqualified, take out the first stainless steel plate on the workbench; if the monitoring result is to continue running, perform step S4.

[0043] Step S4: Mark the position data {M 21 , M 22 …M 23} corresponding to the data {M2, M2…M2} on the measuring shaft. The moving position of the first loading plate will also record position data through the scale axis. The starting points of the scale axes used by the first loading plate and the first laser rangefinder are the same; The electric push rod inside the support plate drives the first slider to move. The first slider drives the first loading plate to move to position M 23 . The external robotic arm places the stainless steel bottom plate between the first loading plate and the second loading plate. The electric push rod inside the first slider drives the second loading plate to approach the first loading plate, thereby clamping the stainless steel bottom plate. The opposite surfaces of the first loading plate and the second loading plate are respectively attached to the two side walls of the installation slot, so that the position of the stainless steel bottom plate and the installation slot is aligned horizontally;

[0044] The workbench continues to move upward, and the height of the light-emitting center of the second laser rangefinder from the bottom surface of the first loading port is set to h. The data measured by the second laser rangefinder are recorded as {Z1, Z1…Z1}, {Z2, Z2…Z2} and {Z3} in sequence. When the data is collected to a {Z3}, the workbench stops moving;

[0045] Among them, Z1 represents the distance from the light emitting center of the second laser rangefinder to the inner wall on the other side of the machine body when the first stainless steel plate does not reach the measuring range of the second laser rangefinder; Z2 represents the distance from the light emitted by the second laser rangefinder to the inner wall on the other side of the machine body after passing through the mounting groove when the first stainless steel plate reaches the measuring range of the second laser rangefinder, Z1=Z2; Z3 represents the distance from the light emitting center of the second laser rangefinder to the outer surface of the first stainless steel plate below the mounting groove; Z3 represents the distance from the second laser rangefinder to the side wall of the workbench when the workbench reaches the measuring range of the second laser rangefinder;

[0046] The workbench continues to move upward for a distance h and then stops. At this time, the bottom surface of the installation groove and the bottom surface of the loading port 1 are on the same plane, so that the position of the stainless steel bottom plate and the installation groove are aligned in the vertical direction. The external robotic arm pushes the stainless steel bottom plate inward so that the stainless steel bottom plate is completely placed above the workbench.

[0047] Step S5, the workbench continues to move up to the second assembly area, the workbench is embedded in the second loading port, and the external mechanical arm inserts the second and third stainless steel plates placed opposite each other between the extrusion plates and the limit plates on both sides respectively, and the insertion is stopped when the second and third stainless steel plates are fitted with the positioning plates, and the hydraulic cylinder inside the extrusion plate drives the slider three to move vertically, and when the slider three moves down, the rope winding device is released; when the slider three moves up, the rope winding device is tightened; so that the slider three is located at the top of the stainless steel plate standing on the side, the cylinder three contracts and drives the limit plate to approach the extrusion plate, and the stainless steel plate standing on the side is clamped by the limit plate and the extrusion plate, and the cylinder two extends and drives the stainless steel plate standing on the side to move toward the center, and the stainless steel plate standing on the side will push the stainless steel bottom plate after contacting the stainless steel bottom plate, so that the stainless steel bottom plate and the first stainless steel plate are fitted together, so that the bottom of the stainless steel plate standing on the side is spliced ​​with the stainless steel bottom plate;

[0105] The present invention combines the data measured by the laser rangefinder 15 with the relative positions of the workbench 8, the first stainless steel plate 12 and the inner wall of the body 1. The moving position of the laser rangefinder 15 will be recorded as position data through the scale axis, so that the data measured by the laser rangefinder 15 has corresponding position data. The scale axis is used as a medium to locate the relative positions of the assembly mechanism 1, the first stainless steel plate 12 and the stainless steel bottom plate 16, so that the device can be adjusted in real time according to the specifications of the stainless steel bottom plate 16, without having to input the specification data of the stainless steel bottom plate 16 into the system in advance, thereby improving the efficiency of assembly.
