Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical automatic detection, and particularly relates to a headlamp electrical detection device with multi-station parallel operation. Background Art

[0002] With the increasing size of headlamps, the detection difficulty of various optical properties of headlamps is getting higher and higher, which has led to an increase in the electrical detection beat of headlamps. However, the customer demand is increasing day by day, and the production beat of large through-type headlamps needs to be as fast as possible. The traditional detection methods are time-consuming and laborious, and it is difficult to meet the high-beat production. In order to improve the production beat, the means often adopted is to increase the number of electrical detection stations, and in the automated production line, a manipulator is also used for handling in cooperation with a multi-station detection machine for optical property detection. This has caused problems such as large floor space occupation, high cost; waste of a certain beat due to the back-and-forth handling of the manipulator; and increased debugging and maintenance costs. Summary of the Invention

[0003] The purpose of the present invention is to solve the defects and deficiencies in the prior art, and provide a headlamp electrical detection device with multi-station parallel operation, which can realize simultaneous detection of multiple stations while the actions of each station do not interfere with each other, and can effectively make up for the bottleneck of the electrical detection beat of the production line.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is: a headlamp electrical detection device with multi-station parallel operation, including a carrier plate assembly, an operation platform, a double-speed chain conveyor line, a machine frame, and a long-stroke synchronous lifting mechanism;

[0005] The double-speed chain conveyor line is used to convey the carrier plate assembly, and the long-stroke synchronous lifting mechanism is used to drive the carrier plate assembly to perform up-and-down lifting movement to realize the switching of the carrier plate assembly between the double-speed chain conveyor line and the operation platform;

[0006] The operation platform includes two support plates located above the double-speed chain conveyor line and capable of performing opening and closing movements in the horizontal direction, and the support plates are provided with positioning members matching the carrier plate assembly;

[0007] The long-stroke synchronous lifting mechanism includes two groups of lifting components arranged symmetrically left and right, a synchronous linkage member is arranged between the two groups of lifting components, and the two groups of lifting components can perform synchronous lifting actions under the action of the synchronous linkage member.

[0008] Preferably, the carrier plate assembly includes a carrier plate, a guiding and limiting column and a profile bottom frame arranged on the carrier plate, and the carrier plate is also provided with a positioning pin sleeve matching the positioning pin on the support plate.

[0009] Preferably, the working platform includes an upper frame plate, a lower frame plate, support profiles arranged between the upper frame plate and the lower frame plate, and strengthening profiles arranged on the upper frame plate. The two support plates are symmetrically arranged on the upper frame plate, and both support plates are connected with driving cylinders and can move towards or away from each other under the action of the driving cylinders.

[0010] Preferably, limit blocks corresponding to the support plates are also arranged on the upper frame plate, and the limit blocks are located on the sides of the support plates away from each other.

[0011] Preferably, the double-speed chain conveyor line is arranged between the upper frame plate and the lower frame plate, and the double-speed chain conveyor line is fixed on the machine frame through the lower frame plate.

[0012] Preferably, the lifting assembly includes a mounting plate and a lifting plate located above the mounting plate. The lifting plate is connected with a long-stroke main cylinder and a ball guide rail on the mounting plate, and the lifting plate can perform lifting movement along the ball guide rail under the action of the long-stroke main cylinder. A limit buffer corresponding to the ball guide rail is also arranged at the bottom of the mounting plate.

[0013] Preferably, the synchronous linkage includes a right-angle output worm gear and worm box installed at the bottom of the lifting plate through a worm connecting seat. One output end of the right-angle output worm gear and worm box is connected to one output end of another right-angle output worm gear and worm box through a synchronous connecting shaft, and the other output end of the right-angle output worm gear and worm box is connected through a worm shaft to penetrate the mounting plate.

[0014] Preferably, positioning members and supporting members for positioning and supporting the carrier plate assembly are also arranged on the lifting plate, and the supporting members are distributed at the four corners of the lifting plate.

[0015] Preferably, the machine frame includes a table board, a frame, a communication panel, a switch panel and a button panel. Mounting holes matching the long-stroke synchronous lifting mechanism are formed on the table board, and mounting holes for a manipulator or a crimping mechanism are also reserved on the table board.

[0016] After adopting the above technical solutions, a multi-station parallel headlight electrical inspection device provided by the present invention has the following beneficial effects:

[0017] The present invention conveys the carrier plate assembly through the double-speed chain conveyor line. In one of the parallel stations, the long-stroke synchronous lifting mechanism will lift the carrier plate assembly. After being supported by the working platform and having corresponding secondary precise positioning, due to the relatively high height of the working platform, this ensures that the next carrier plate assembly can continue to flow smoothly without waiting for the completion of the operation at the previous working station and can perform the next same operation. Thus, a multi-station parallel operation layout is formed, effectively decomposing the bottleneck beat and improving the overall production beat of the production line.

[0018] In summary, through the parallel operation of multiple detection stations in the present invention, the front and rear detection stations do not interfere with each other and work independently, which can effectively make up for the bottleneck of the electrical inspection beat of the automatic production line. At the same time, the application of the long-stroke synchronous lifting mechanism can improve the stability of the structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular forms are also intended to include the plural forms. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they specify the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0027] Unless otherwise specifically stated, the relative arrangements of the components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the authorized specification. In all the examples shown and discussed herein, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, further discussion thereof is not required in subsequent drawings.

[0028] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom" are generally based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and thus should not be construed as limiting the protection scope of the present invention; the orientation words "inner, outer" refer to the inside and outside relative to the contour of each component itself.

[0029] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. can be used here to describe the spatial positional relationship of a device or feature shown in the figure with other devices or features. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figure for the device.

[0030] In addition, it should be noted that the use of terms such as "first", "second" etc. to define components is only for the convenience of differentiating the corresponding components. Without additional statements, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of the present invention.

[0031] As Figures 1-5 shown, a multi-station parallel headlight electrical inspection device provided by the present invention includes a carrier plate assembly 1, an operation platform 2, a double-speed chain conveyor line 3, a machine frame 4, and a long-stroke synchronous lifting mechanism 5.

[0032] The double-speed chain conveyor line 3 is used to convey the carrier plate assembly 1, and the long-stroke synchronous lifting mechanism 5 is used to drive the carrier plate assembly 1 to perform up and down lifting movements, so as to realize the switching of the carrier plate assembly 1 between the double-speed chain conveyor line 3 and the operation platform 2. The operation platform 2 includes two support plates 10 located above the double-speed chain conveyor line 3 and capable of performing opening and closing movements in the horizontal direction. The support plates 10 are provided with positioning members matching the carrier plate assembly 1. The long-stroke synchronous lifting mechanism 5 includes two groups of lifting components symmetrically arranged left and right. A synchronous linkage member is arranged between the two groups of lifting components, and the two groups of lifting components can perform synchronous lifting actions under the action of the synchronous linkage member.

[0033] The carrier plate assembly 1 includes a carrier plate 6, and guide and limit columns 7 and profile bottom frames 8 provided on the carrier plate 6. The carrier plate 6 is also provided with a positioning pin sleeve 9 matching the positioning pins 11 on the support plates 10. With such a design, when the carrier plate assembly 1 is lifted in place, the support plates 10 can not only support the carrier plate assembly 1 when closed, but also accurately position the carrier plate assembly 1 through the positioning pins 11.

[0034] The operation platform 2 includes an upper frame plate 13, a lower frame plate 15, a support profile 14 disposed between the upper frame plate 13 and the lower frame plate 15, and a reinforcing profile 12 disposed on the upper frame plate 13. The two support plates 10 are symmetrically arranged on the upper frame plate 13, and both of the two support plates 10 are connected with driving cylinders 16 and can move in a direction close to or away from each other under the action of the driving cylinders 16. With such a design, it can be ensured that there is no interference during the up and down movement of the carrier plate assembly 1. Further, a limit block 17 corresponding to the support plate 10 is also provided on the upper frame plate 13. The limit block 17 is located on the side where the support plates 10 are away from each other, and the opening and closing stroke of the support plate 10 can be adjusted through its limiting effect to ensure the dimensional consistency.

[0035] The double-speed chain conveyor line 3 is disposed between the upper frame plate 13 and the lower frame plate 15. Specifically, the double-speed chain conveyor line 3 is fixed on the machine frame 4 through the lower frame plate 15.

[0036] Since the large-size carrier plate assembly 1 is lifted by a single cylinder, it is difficult to lift to a relatively high height. While using a double-cylinder lift, there will be problems such as the tilting or even overturning of the carrier plate assembly 1 caused by non-synchronization. Therefore, it is necessary to design the synchronous long-stroke synchronous lifting mechanism of the present invention. Specifically, the lifting assembly of the synchronous long-stroke synchronous lifting mechanism includes a mounting plate 18 and a lifting plate 21 located above the mounting plate 18. The lifting plate 21 is connected with a long-stroke main cylinder 27 and a ball guide rail 29 on the mounting plate 18. Specifically, the output end of the long-stroke main cylinder 27 is connected with the lifting plate 21 through a floating joint, and the lifting plate 21 is guided by the ball guide rail 29, that is, the lifting plate 21 can perform lifting movement along the ball guide rail 29 under the action of the long-stroke main cylinder 27. A limit buffer 28 corresponding to the ball guide rail 29 is also provided at the bottom of the mounting plate 18 to adjust the jacking position and have a certain buffering effect. The synchronous linkage includes a right-angle output worm and worm gear box 24 mounted on the bottom of the lifting plate 21 through a worm connecting seat 25. One output end of the right-angle output worm and worm gear box 24 is connected with one output end of another right-angle output worm and worm gear box 24 through a synchronous connecting shaft 23. The other output end of the right-angle output worm and worm gear box 24 is connected through a worm shaft 26 to penetrate the mounting plate 18. Due to the large span, with such a design, the consistency of the synchronous movement of the two groups of lifting assemblies can be achieved.

[0037] Positioning members 19 and supporting members 20 for positioning and supporting the carrier plate assembly 1 are also provided on the lifting plate 21. The supporting members 20 are distributed at the four corners of the lifting plate 21. With such a design, the positioning and supporting problems of the carrier plate assembly 1 during the lifting process can be solved to ensure the lifting accuracy.

[0038] The machine frame 4 includes a table board 30, a frame 31, a communication panel 32, a switch panel 33, and a button panel 34. The table board 30 is provided with mounting holes matching the long-stroke synchronous lifting mechanism 5, and multiple mounting holes for various actuators such as a manipulator or a crimping mechanism are also reserved on the table board 30. Through the design of the communication panel 32, the switch panel 33, and the button panel 34, it is convenient for operation and debugging, and the frame 31 is used to support the entire structure and serve as an electrical box. Further, connection blocks are used to achieve the front-to-back connection during the assembly of multiple machines, ensuring the relative levelness of the front and rear machines. Each single module is fully functional and can be applied to various processes of headlight assembly.

[0039] When the multi-station parallel headlight electrical inspection device of the present invention is in use, a carrier plate assembly is conveyed to a parallel station through a double-speed chain conveyor line 3. The long-stroke synchronous lifting mechanism 5 will drive the carrier plate assembly 1 to lift upward. At this time, the support plate 10 on the operation platform 2 is in the open position. When the carrier plate assembly 1 is lifted in place, the support plate 10 closes inward and supports on both sides of the bottom surface of the carrier plate assembly 1. At this time, the long-stroke synchronous lifting mechanism 5 resets, and the double-speed chain conveyor line 3 can continue to convey the next carrier plate assembly. When the carrier plate assembly on the operation platform 2 needs to be removed, the long-stroke synchronous lifting mechanism 5 lifts upward to the bottom surface of the carrier plate assembly, and the support plate 10 opens outward, disengaging the limit on the carrier plate assembly. At this time, the long-stroke synchronous lifting mechanism 5 drives the carrier plate assembly to reset downward, and the carrier plate assembly can return to the double-speed chain conveyor line 3 again.

[0040] In summary, the multi-station parallel headlight electrical inspection device provided by the present invention, through the parallelism of multiple inspection stations, the front and rear inspection stations do not interfere with each other and work independently, which can effectively make up for the bottleneck of the electrical inspection beat of the automatic production line. At the same time, the application of the long-stroke synchronous lifting mechanism can improve the stability of the structure.

[0041] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
