[0027] A further embodiment of the present invention comprises a lateral combined positioning device 24 , a front compartment plate positioning device 36 , a compartment width adjustment mechanism 27 and a parallelogram telescopic pushing mechanism 33 .

[0028] The lateral combined positioning device 24 includes a side compartment plate lower positioning mechanism and a bottom compartment plate lateral positioning mechanism. One set of mechanisms has two positioning functions. The lateral combined positioning mechanism is sequentially composed of a first servo motor 241 connected to a first reduction box 242, a first reduction box connected to a first bevel gear reversing structure 243, a first bevel gear reversing structure connected to a first screw nut mechanism 244 and a propulsion frame 245.

Under the action of the parallelogram pushing mechanism, the front carriage plate will move forward along the forward and downward arc curve motion trajectory and finally press against the front carriage plate positioning device 36.

[0029] The assembly process steps of the present invention are:

[0030] The first step is to set the compartment width dimension parameters on the touch screen according to the width requirements of the compartment to be assembled. This parameter is the basis for adjusting and controlling the width of the compartment and also the basis for the extension and retraction degree of the corresponding positioning device.

[0031] The second step is to change the tiltable side assembly frame 2 from an upright state to a tilted state.

[0032] The third step is to move the movable front assembly rack 3 from outside the assembly rack to the working position in front of the assembly rack, and to push out the front compartment panel positioning device.

[0033] In the fourth step, the assembly roller 12 takes over the carriage floor from the feed roller 11 and extends the lateral combined positioning device.

[0034] The fifth step is to hoist the carriage panels with a crane, place the left and right carriage panels on the tiltable side assembly frame 2, and place the front carriage panel on the mobile front assembly frame 3. Fix each carriage panel with a vacuum suction cup.

[0035] The sixth step is to turn the left and right side frames of the tiltable side assembly frame from an inclined position to a closing angle (about 89 degrees).

[0036] In the seventh step, the mobile front assembly frame pushes the front carriage plate to a designated position through a parallelogram push-out mechanism.

[0037] In the eighth step, the lifting bottom assembly frame cylinder lifts up the car bottom plate, and moves close to and presses the bottom edges of the left and right side car plates and the front car plate.

[0038] Step 9. Pre-assemble the left and right side panels and the front panel without tightening the bolts.

[0039] The tenth step is to use a crane to lift the rear door frame to the rear end of the car.

[0040] Step 11: Use a crane to lift the roof panel to the designated position on the top of the vehicle.

[0041] In the twelfth step, the left and right side frames are changed from a closed angle to an upright position, the cylinder on the top of the carriage is pressed tightly, and the roof panel is pre-assembled.

[0042] Step 13: Use laser to detect whether the shape and position error of the carriage is within the qualified range. If qualified, tighten all bolts and the assembly is completed.

[0043] Finally, release all the vacuum suction cups, the side assembly frame automatically returns to the inclined state, the front assembly frame moves horizontally to the original position, the bottom assembly frame falls, and the assembled car falls onto the roller conveyor. The powered roller conveyor automatically moves the car from the assembly roller conveyor to the exit roller conveyor, and then moves it out and off the line.
