[0032] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] In response to the shortcomings or one of the shortcomings raised in the above-mentioned background technology, an embodiment of the present application provides an assembly device for an automobile combination instrument, which can automatically assemble the front cover and bracket on the automobile combination instrument together, replacing manual assembly, reducing the difficulty of assembly, and ensuring the consistency and reliability of assembly.

[0034] See also Figures 1 to 5 As shown, an embodiment of the present application provides an assembly device for an automobile combination instrument, comprising:

[0035] A gripping tool, comprising a mounting frame 1 , on which a clamping assembly for clamping a bracket 100 is provided;

[0036] A positioning tool, comprising a support base 2 on which a contoured support block 3 for placing and positioning the front cover 200 is provided;

[0037] The driving device is connected to the mounting frame 1 and is used to drive the mounting frame 1 to approach the support base 2 so that the bracket 100 on the clamping assembly and the front cover 200 on the contoured support block 3 are buckled together.

[0038] The assembly device of the automobile combination instrument in the embodiment of the present application is provided with a grabbing tool and a positioning tool. The grabbing tool is installed on the driving device, and the driving device can drive the grabbing tool to grab the bracket 100. The front cover 200 can be placed and positioned on the positioning tool. After the grabbing tool grabs the bracket 100, the driving device can drive the grabbing tool to approach the positioning tool so that the bracket 100 on the grabbing tool is engaged with the front cover 200 on the positioning tool.

[0039] For example, the drive device of the embodiment of the present application can be a multi-axis robot, which is not shown in the figure. When assembling the bracket 100 and the front cover 200, the front cover 200 is first placed on the contoured support block 3 on the support base 2. The contoured support block 3 ensures that the claws 201 on the front cover 200 face vertically upward. The drive device then drives the gripping fixture to the position where the bracket 100 is placed. The gripping fixture then grips the bracket 100 using the clamping assembly. The gripping fixture is then adjusted using the drive device so that the bracket 100 held by the clamping assembly is directly above the front cover 200.

[0040] At the same time, ensure that the claws 201 on the front cover 200 are oriented towards and aligned with the clamping holes 101 on the bracket 100. Finally, the driving device drives the grasping tool to move downward, so that the bracket 100 clamped on the clamping assembly moves vertically downward, so that the bracket 100 is pressed against the front cover 200. Under the action of the extrusion force, the claws 201 on the front cover 200 are correspondingly clamped into the clamping holes 101 on the bracket 100, completing the assembly of the bracket 100 and the front cover 200, so that the front cover 200 and the bracket 100 on the automobile combination instrument can be automatically assembled together, replacing manual assembly, reducing assembly difficulty, and ensuring assembly consistency and reliability.

[0041] In some alternative embodiments: See Figures 1 to 5 As shown, an embodiment of the present application provides an assembly device for an automobile combination instrument, and a suction component for sucking the front cover 200 is also provided on the mounting frame 1 of the assembly device for the automobile combination instrument. The driving device drives the mounting frame 1 to approach the support seat 2 to place the front cover 200 on the suction component on the contoured support block 3.

[0042] The mounting frame 1 of the embodiment of the present application is also equipped with a suction component, which cooperates with the driving device to drive the mounting frame 1 to move, so that the suction component can suck the front cover 200 and place the front cover 200 on the contoured support block 3 on the support seat 2, thereby realizing automatic discharge of the front cover 200.

[0043] For example, the suction assembly in the embodiment of the present application can be a vacuum suction cup, which can suck the front cover 200 by applying negative pressure. In addition, the support base 2 in the embodiment of the present application is an L-shaped block formed by fixing a horizontal plate and a vertical plate. A reinforcing rib is fixed between the horizontal plate and the vertical plate. The vertical plate is conveniently fixed to one side of the production line conveyor device. The contoured support block 3 is fixedly mounted on the horizontal plate. The contoured support block 3 has a support surface that adapts to the outer surface of the front cover 200.

[0044] In some alternative embodiments: See Figures 1 to 5 As shown, an embodiment of the present application provides an assembly device for an automobile combination instrument, wherein the suction component of the assembly device for the automobile combination instrument includes a mounting plate 4 fixed on a mounting frame 1, and a negative pressure suction head 5 for connecting to an external negative pressure device is provided on the mounting plate 4.

[0045] The suction component of the embodiment of the present application includes a mounting plate 4 fixedly connected to the mounting frame 1, and a negative pressure suction head 5 is fixedly installed on the mounting plate 4. The negative pressure suction head 5 can be connected to an external negative pressure extraction device through an air pipe. By extracting negative pressure, negative pressure is generated at the opening of the negative pressure suction head 5, and then the negative pressure suction head 5 can be used to suck the front cover 200.

[0046] For example, the external negative pressure extraction device in the embodiment of the present application can be an air pump, and the open end of the negative pressure suction head 5 can be covered with a rubber sleeve to prevent scratching the surface of the front cover 200. The mounting frame 1 is U-shaped, and the mounting plate 4 is vertically connected to one end of the mounting frame 1 by bolts. The mounting plate 4 is rectangular, and the four corners of the mounting plate 4 are fixedly mounted with negative pressure suction heads 5, which facilitate the two negative pressure suction heads 5 to cooperate with each other to suck the strip-shaped front cover 200.

[0047] In some alternative embodiments: See Figures 1 to 5 As shown, an embodiment of the present application provides an assembly device for an automobile combination instrument, wherein the clamping component of the assembly device for the automobile combination instrument includes a clamping cylinder 6 and a clamping plate 7 fixed on a mounting frame 1, and a tightening pin 8 for cooperating with the clamping plate 7 is fixed at the movable end of the clamping cylinder 6.

[0048] The clamping assembly of the embodiment of the present application includes a clamping cylinder 6 and a clamping plate 7 fixedly connected to the mounting frame 1. A clamping pin 8 facing the clamping plate 7 is fixed to the movable end of the clamping cylinder 6. The clamping cylinder 6 can drive the clamping pin 8 to tighten the bracket 100, thereby fixing the bracket 100 to the clamping plate 7. Because the side of the bracket 100 facing away from the mounting surface of the front cover 200 does not have a flat large surface, the clamping pin 8 is provided to achieve tightening.

[0049] It should be noted that the movable end of the clamping cylinder 6 in the embodiment of the present application is fixed with at least three jacking pins 8 to ensure clamping stability. For example, the mounting frame 1 is U-shaped, with the mounting plate 4 vertically bolted to one end of the mounting frame 1. The other end of the mounting frame 1 is fixedly connected to the clamping plate 7 via bolts. The clamping cylinder 6 is fixedly mounted on the mounting frame 1 and positioned above the clamping plate 7. The movable end of the clamping cylinder 6 is fixedly connected to three jacking pins 8 distributed along the length of the clamping plate 7.

[0050] In some alternative embodiments: See Figures 1 to 5 As shown, an embodiment of the present application provides an assembly device for an automobile combination instrument, wherein a profiling support block 3 of the assembly device for the automobile combination instrument is provided with an adsorption component for adsorbing the front cover 200 onto its support surface.

[0051] The contoured support block 3 of the embodiment of the present application is provided with an adsorption component that can adsorb the front cover 200 to prevent the front cover 200 from sliding and misaligning on the contoured support block 3 and affecting assembly accuracy. For example, the adsorption component in this embodiment can be a suction cup or an adhesive patch.

[0052] In some alternative embodiments: See Figures 1 to 5As shown, an embodiment of the present application provides an assembly device for an automobile combination instrument. The adsorption component of the assembly device for the automobile combination instrument includes a negative pressure air path 9 arranged on a contoured support block 3 and extending to its support surface. The end of the negative pressure air path 9 away from the contoured support block 3 is provided with an air path connector 10 for connecting to an external negative pressure extraction device.

[0053] The adsorption component of the embodiment of the present application includes a negative pressure air circuit 9 and an air circuit connector 10 opened on the contoured support block 3. One end opening of the negative pressure air circuit 9 is set on the support surface, and the other end opening is connected to the air circuit connector 10. The air circuit connector 10 is connected to an external negative pressure pumping device through an air pipe. By pumping negative pressure through the external negative pressure pumping device, negative pressure can be generated at the open end of the negative pressure air circuit 9 located on the support surface, thereby generating suction on the front cover 200 placed on the contoured support block 3, thereby preventing the front cover 200 from sliding and dislocating on the contoured support block 3 and affecting the assembly accuracy.

[0054] In some alternative embodiments: See Figures 1 to 5 As shown, an embodiment of the present application provides an assembly device for an automobile combination instrument, wherein the support base 2 of the assembly device for the automobile combination instrument is provided with a limiting component located on the peripheral side of the support base 2 and used to prevent the front cover 200 from sliding on the contoured support block 3.

[0055] The support base 2 of the present embodiment is provided with a limiting assembly located around the support base 2. The limiting assembly can limit the front cover 200 to prevent the front cover 200 from sliding on the contoured support block 3 and affecting the assembly accuracy. For example, the limiting assembly can be a limiting post or a limiting block.

[0056] In some alternative embodiments: See Figures 1 to 5 As shown, an embodiment of the present application provides an assembly device for an automobile combination instrument, wherein the limiting component of the assembly device for the automobile combination instrument includes a plurality of ejector cylinders 11 arranged on a support base 2, and the movable ejectors 12 of the plurality of ejector cylinders 11 pass through the support base 2 and are distributed around the support surface on the contoured support block 3.

[0057] The limiting assembly of the embodiment of the present application includes a plurality of ejector cylinders 11 installed on the support base 2, and the movable ejectors 12 of the plurality of ejector cylinders 11 penetrate the support base 2 upward and are distributed around the supporting surface of the contoured support block 3. The supporting surface of the contoured support block 3 has an arc surface and an inclined surface that adapt to the outer surface of the front cover 200. The plurality of movable ejectors 12 can effectively assist the front cover 200 on the limiting support surface to prevent the front cover 200 from slipping on the inclined surface.

[0058] It should be noted that the movable ejector 12 can be controlled in extension and retraction height by the ejector cylinder 11. When the bracket 100 is pressed down and engaged with the front cover 200, the movable ejector 12 can be controlled to retract before the bracket 100 almost contacts the movable ejector 12 to prevent the movable ejector 12 from directly colliding with the surface of the bracket 100.

[0059] In some alternative embodiments: See Figures 1 to 5 As shown, an embodiment of the present application provides an assembly device for an automobile combination instrument, wherein the support surface of the contoured support block 3 of the assembly device for the automobile combination instrument includes an arc surface and an inclined surface for adapting to the outer surface of the front cover 200, and the inclined surface and the arc surface jointly support the front cover 200 so that the claw 201 on the front cover 200 is vertically upward.

[0060] The front cover 200 of the embodiment of the present application is a curved special-shaped part. When looking at the cross section, one end of the front cover 200 is tilted upward to form a curved portion and an inclined portion, and a vertically upward claw 201 is integrally connected to the curved portion and the inclined portion.

[0061] The supporting surface of the contoured support block 3 is composed of an arc surface and an inclined surface, which are tangent to each other. The arc surface is used to fit the curved part of the supporting front cover 200, and the inclined surface is used to fit the inclined part of the supporting front cover 200, so that the claw 201 on the front cover 200 can be maintained in the vertical direction, making it convenient for the bracket 100 to be pressed down and buckled.

[0062] It should be noted that in this embodiment, six claws 201 are integrally connected to the front cover, and the six claws 201 are distributed on the edges of the front cover. The three claws 201 located on the inclined portion form an angle of 43 degrees with the inclined portion. When the front cover 200 is manually pressed and fastened to the bracket 100, the pressing surface is on the inclined portion. The horizontal component force generated during pressing can easily cause the claws 201 to shift laterally and fail to fit into place.

[0063] The assembly device of the present application can position the front cover 200 by the contoured support block 3 on the positioning tool, and then clamp the bracket 100 by grabbing the clamping assembly on the tool, and then use the driving device to drive the bracket 100 to press the front cover 200, so that the front cover 200 is stably fastened to the bracket 100, thereby replacing manual assembly, reducing the difficulty of assembly, and ensuring the consistency and reliability of assembly.

[0064] In some alternative embodiments: See Figures 1 to 5 As shown, an embodiment of the present application provides an assembly device for an automobile combination instrument. The driving device of the assembly device for the automobile combination instrument is a multi-axis robot, and the movable end of the multi-axis robot is fixedly connected to the mounting frame 1 through the mounting shaft 13.

[0065] The driving device of the embodiment of the present application is a multi-axis robot, and the movable end of the multi-axis robot is fixedly connected to the mounting frame 1 through the mounting shaft 13. Since the multi-axis robot has multiple degrees of freedom, it can drive the mounting shaft 13 to rotate, flip or translate, so as to facilitate the suction component on the mounting frame 1 to freely absorb the front cover 200, and facilitate the clamping component on the mounting frame 1 to freely clamp the front cover 200.

[0066] In some alternative embodiments: See Figures 1 to 5 As shown, an embodiment of the present application provides an assembly device for an automobile combination instrument, which also includes a front cover tray and a bracket tray. The front cover tray is provided with a groove for placing the front cover 200, and the bracket tray is provided with a vertical slot for inserting the bracket 100.

[0067] The assembly device of the embodiment of the present application also includes a front cover tray and a bracket tray that cooperate with the gripping tool. Neither the front cover tray nor the bracket tray is shown in the figure. Specifically, the front cover tray is provided with a groove for receiving the front cover 200. After the front cover 200 is placed in the groove, the claws 201 on the front cover 200 face upward, facilitating the suction assembly on the mounting frame 1 to move vertically downward with the mounting frame 1 and absorb the front cover 200. The bracket tray is provided with a vertical slot for inserting the bracket 100. After the bracket 100 is inserted into the vertical slot, the upper end of the bracket 100 is exposed, facilitating the clamping assembly on the mounting frame 1 to flip downward with the mounting frame 1 and clamp the front cover 200.
