DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the utility model clearer and more understandable, the utility model will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

[0029] Please refer to the accompanying Figure 1 and the accompanying Figure 2 , the utility model provides a kind of automobile aftertreatment assembly line, comprising: conveying line 100, several assembly stations are sequentially configured on it;Upper conveying chain 110 and lower conveying chain 120, upper and lower parallel arrangement on the conveying line 110;Double-layer damping tray 200, the upper conveying chain 110 will double-layer damping tray 200 from the first end of the conveying line 100 via each assembly station is transported to its tail end, and the lower conveying chain 120 will double-layer damping tray 200 from the tail end of the conveying line 100 is transported to its first end;Elevator 300, the number is two, respectively configured at the first end and tail end of the conveying line 100, for lifting double-layer damping tray 200 to the height corresponding with upper conveying chain 110 or lower conveying chain 120, to realize that double-layer damping tray 200 is in the shape of back-to-back circular conveying.

[0030] In the application, upper conveying chain 110, lower conveying chain 120, double-layer damping tray 200 are all prior art, workpiece is placed on the upper tray of double-layer damping tray 200, and the upper tray can rotate when staff pulls the upper tray, to facilitate the installation of each component at an angle. Multiple assembly stations are integrated on a conveying line 100, and the upper conveying chain 110 can orderly convey double-layer damping tray 200 to any assembly station to carry out the assembly work of specific parts at the assembly station, to meet the needs of many types of automobile aftertreatment, large structural differences and complicated assembly procedures at the present stage;Two elevators 300 cooperate with upper and lower conveying chains to realize the back-to-back circular conveying of double-layer damping tray 200, and double-layer damping tray 200 is conveyed by upper conveying chain 110 and recycled by lower conveying chain 120, to save space;The conveying chain of conveying line adopts active power speed-up chain, the conveying speed is adjustable at 2-10 m / min, the height of line body meets the man-machine engineering requirement, and the line body meets the wiring harness assembly of national six diesel S type, U type and box type products, and product circulation is stable.

[0031] In this application, to ensure that the double-layer damping tray 200 pauses at the required assembly station, a stopper 400 is provided between the conveyor line 100 and the elevator 300 and / or between each of the assembly stations. The stopper 400 has been disclosed in the prior art and will not be described in detail here. Initially, the stopper 400 rises. When the double-layer damping tray 200 passes the stopper 400, it is stopped at the assembly station. After assembly is completed, the stopper 400 descends, and the double-layer damping tray is transported downstream.

[0032] Furthermore, to enhance the intelligence of the assembly line, each assembly station is equipped with an emergency stop button and a photoelectric sensor connected to the control system and used in conjunction with the stop device 400. After assembly is completed and the workpiece is lifted out, the double-layer damping pallet 200 descends to the end of the lower conveyor chain 120 via the elevator 300, returns to the beginning of the lower conveyor chain 120, and then returns to the operating station via the elevator 300. The conveyor line 100 is equipped with three-color warning lights, and each assembly station is equipped with an emergency stop button. In case of emergency, the employee presses the emergency stop button, and the line (i.e., the upper conveyor chain 110 and the lower conveyor chain 120) stops moving. Next to the emergency stop button is a release button. After the workpiece is assembled at the assembly station, the photoelectric sensor confirms that there is no workpiece at the next assembly station. After the employee presses the release button, the stop device 400 descends, and the workpiece moves to the next assembly station. If there is a workpiece at the next assembly station, the stop device 400 will not descend when the release button is pressed. The double-layer damping tray 200 returns from the lower conveyor chain 120 and moves to the front of the elevator 300 at the first end to stop. After the photoelectric sensor detects that the elevator 300 has descended to the lower conveyor chain 120, the stop device 400 opens, and the double-layer damping tray 200 moves to the elevator 300. It then rises to the upper conveyor chain 110 with the lifting mechanism. After the tray movement is completed, the elevator 300 automatically descends to the lower conveyor chain 120.

[0033] In this application, as attached Figure 3 As shown, the lifting platform 300 includes: a base frame 310 with an opening on one side near the conveyor line 100; a lifting roller conveyor 320 located inside the base frame 310; and a lifting drive 330 for driving the lifting roller conveyor 320 to rise and fall within the base frame 310, so that the height of the lifting roller conveyor 320 corresponds to the height of the upper conveyor chain 110 or the lower conveyor chain 120. The lifting drive 330 drives the lifting roller conveyor 320 to rise and fall, achieving height matching between the upper conveyor chain 110 and the lower conveyor chain 120, thus completing the U-shaped operation of the double-layer damping tray 200. The lifting roller conveyor 320 is a combination of several rollers; during the movement of the double-layer damping tray 200, the rollers rotate around their axes, reducing friction.

[0034] In a specific embodiment, the lifting driving member 330 is a ball screw feeding mechanism. The ball screw feeding mechanism is a prior art, and its connection relationship and working principle are not described here.

[0035] To ensure the safety of the double-layer damping tray 200, the guardrails 340 are arranged on the side surfaces of the chassis 310 except the opening.

[0036] At least one balancer 500 is arranged on the conveying line 100 corresponding to any assembly station. The balancer is used to hang the tightening gun required for assembling each component.

[0037] To improve heat dissipation, the fans 600 are arranged on the conveying line 100 between two adjacent assembly stations.

[0038] To further detect the air tightness of the workpiece, the air tightness detector 700 is arranged on the conveying line 100 at one of the assembly stations. To further conduct live detection on the assembly of the electrical element, the electrical signal detector 800 is arranged on the conveying line 100 at one of the assembly stations.

[0039] To facilitate the binding of the workpiece information and the product and the traceability, the visual photographing system 900 is arranged on the conveying line 100 at the assembly station closest to the tail end of the conveying line 100.

[0040] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the examples, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and they should be included in the scope of the claims of the present application.
