[0032] The present invention will be further described below with reference to embodiments:

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0034] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this invention, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0035] The laser brazing process for the top cover requires high precision in part matching and tooling. As a covering component, the top cover is weaker and larger than structural components, making it prone to sheet metal deformation during transport and assembly, which negatively impacts assembly clearances. Therefore, this invention discloses a precision positioning device with inspection and transport functions.

[0036] The top cover outer panel precision positioning device with detection and transfer functions includes a transfer frame 1, a positioning frame 2, a front traction device 3, two front limiting devices 4, a front auxiliary positioning device I 5, a front auxiliary positioning device II 6, two front flip Z-direction protection devices 7, two rear flip Z-direction protection devices 8, two rear limiting and positioning devices 9, and a rear traction device 10.

[0037] The front traction device 3 can be connected to the internal electric tractor, facilitating transportation within the workshop.

[0038] The two front limiting devices 4 are arranged symmetrically on the left and right sides, and play a role in preventing cross-movement in the Y direction during the transfer of parts of the top cover outer panel.

[0039] The front auxiliary positioning device I5 has a positioning pin 57, which coincides with the mounting hole of the luggage rack on the right front side of the top cover outer panel.

[0040] The front auxiliary positioning device II6 has a positioning Y-direction diamond pin on top, which coincides with the luggage rack mounting hole on the left front side of the top cover outer panel. The two auxiliary positioning devices play an auxiliary positioning role in placing the top cover outer panel parts into the device of the present invention. Pressing the handle 52 of the auxiliary positioning device I5 and the auxiliary positioning device II6 will cause the luggage rack mounting hole of the top cover to fall into the positioning pin 57 of the auxiliary positioning device I5 and the auxiliary positioning device II6, and perform X-direction and Y-direction auxiliary positioning.

[0041] The two front flip Z-direction protection devices 7 and the two rear flip Z-direction protection devices 8 serve as Z-direction anti-slip and protection devices. During use, the rocker arms of the front flip Z-direction protection devices 7 and the rear flip Z-direction protection devices 8 can be lowered to provide Z-direction protection.

[0042] The rear limiting and positioning devices 9 are arranged symmetrically on the left and right sides, serving to position the rear of the top cover in the X and Y directions, provide support in the Z direction, and limit movement in the Y direction. The design of the two positioning pins 93 on the left and right sides ensures accurate positioning of the top cover in the Y and X directions and accurate support of the Z-direction surface on the device of the present invention. The two positioning blocks 95 serve to limit movement and provide protection in the Y direction. The rear traction device 10 can connect multiple transfer devices, connecting the front traction device 3 and the rear traction device 10 of the device of the present invention, enabling the simultaneous transportation of multiple devices of the present invention.

[0043] The transfer frame 1 includes a transfer frame body 11, two directional transfer casters 12, four forklift forklift square tubes 13, four sets of intermediate guide wheels 14, four sets of Z-axis positioning blocks 15, two omnidirectional transfer casters 16, four sets of corner guide wheels 17, and a limiting block 18.

[0044] The forklift forklift square tube 13 is welded and fixed to the bottom of the transfer frame body 11, facilitating the transfer of the top cover from the stamping workshop to the welding workshop using a box truck for handling, loading, and unloading. The two directional transfer casters 12, four sets of intermediate guide wheels 14, two omnidirectional transfer casters 16, and four sets of corner guide wheels 17 are respectively fixed to the bottom of the transfer frame body 11. Specifically, the two directional transfer casters 12 are fixed to the left and right sides of the rear bottom of the transfer frame body 11; the two omnidirectional transfer casters 16 are fixed to the left and right sides of the front bottom of the transfer frame body 11; the four sets of intermediate guide wheels 14 are distributed sequentially from front to back along the center line of the bottom of the transfer frame body 11; and the four sets of corner guide wheels 17 are respectively fixed to the four corners of the rectangular frame at the bottom of the transfer frame body 11. The intermediate guide wheel 14 and the corner guide wheels 17 guide the device when it enters the precision positioning inlet, guiding it to quickly reach the accurate position and ensuring its Y-axis accuracy within the inlet. The four sets of Z-axis positioning blocks 15 are located on the left and right sides, respectively, at the front and rear of the bottom of the transfer frame body 11, and cooperate with the positioning surface of the precision positioning inlet to ensure the Z-axis accuracy of the device within the inlet. The limiting block 18 is located at the rear of the transfer frame body 11 and cooperates with the precision positioning inlet positioning detection sensor to ensure the X-axis accuracy of the device within the inlet.

[0045] The positioning frame 2 includes a positioning frame body 21, four Y-direction limiting guide devices 22, ten contour support positioning blocks 23, device nameplates 24, five intermediate support positioning blocks 25, six reference holes, six reference hole protective covers 26, and six reference hole coordinate labels 27.

[0046] The four Y-axis limiting guide devices 22 are divided into two groups and fixed to the top left and right sides of the positioning frame body 21 by bolts. During the placement of the top cover, the Y-axis limiting guide devices 22 provide Y-axis guidance, facilitating the smooth and accurate placement of the top cover onto the device. The ten contour support positioning blocks 23 are divided into two groups of five, respectively located on the top left and right sides of the positioning frame body 21. Of the five intermediate support positioning blocks 25, four are located at the top of the positioning frame body 21 and one at the bottom. The contour support positioning blocks 23 and intermediate support positioning blocks 25 are made of inspection tool material, with surfaces machined according to the product contour, serving as support and rapid inspection functions. After the top cover is placed on the device, the surface accuracy can be quickly determined based on the fit between the top cover and the contour support positioning blocks 23 and intermediate support positioning blocks 25. Simultaneously, the Z-axis accuracy of the top cover on the device is ensured. Ten contour support positioning blocks 23 and five intermediate support positioning blocks 25 are connected to the positioning frame by pins. They can be customized and replaced according to different products to meet the flexible use requirements of the products.

[0047] The device nameplate 24 is fixed to the top of the positioning frame body 21 by bolts. The top first, third and fourth intermediate support positioning blocks 25 have 6 reference holes on both sides, and 6 reference hole protective covers 26 are provided on them. 6 reference hole coordinate plates 27 are also screwed onto the mounting plates of the 6 reference hole protective covers 26.

[0048] The transfer frame 1 and the positioning frame 2 are connected by precision-machined connecting pins to ensure positioning accuracy and strength. Specifically, both the transfer frame 1 and the positioning frame 2 are equipped with multiple connecting plates, and the connection positions on the connecting plates are combined with pins, which can be used in any size combination to meet the flexible switching requirements of vehicle models.

[0049] The front traction device 3 is fixed to the front of the transfer frame 1 by bolts, and includes a traction component 31, a connecting component 32, and two pins 33. The traction component 31 provides a rigid connection; the connecting component 32 fixes the pins 33 and connects the traction component 31; the two pins 33 ensure relative rotational movement between the connecting component 32 and the pins 33 during transfer, thus ensuring smooth transport of the device during transfer.

[0050] The front limiting device 4 includes a support 41, a component label 42, a gasket 43, two positioning blocks 44, a gasket label 45, and two connecting blocks 46. The positioning blocks 44 are made of high-density nylon material, which prevents collisions with metal parts and increases wear resistance. The component label 42 contains the drawing number information of the rear limiting device 4, facilitating reference to machining drawings. The gasket label 45 clearly indicates the gasket specifications and model, allowing for quick location of the gasket to be adjusted or replaced during precision adjustments of the front limiting device 4.

[0051] The auxiliary positioning device I5 includes a pin 51, a handle 52, a double-ear connecting plate 53, a bushing connecting block 54, a bushing 55, a pin seat 56, a positioning pin 57, two connecting blocks 58, and a washer 59. It ensures the top cover's accuracy in the X and Y directions of the device. Specifically, the handle 52 is connected to the double-ear connecting plate 53 via the pin 51, allowing the handle 52 to rotate around the X-axis; the bushing connecting block 54 is fixed to the double-ear connecting plate via screws; the pin seat 56 is connected to the bushing connecting block 54 via the bushing 55, allowing for relative movement in the Z direction; the positioning pin 57 is fixed to the pin seat 56 via screws; the two connecting blocks 58 are fixed via screws; and the washer 59 is fixed between the connecting blocks 58 and the bushing connecting block 54 via screws, with the Y-direction accuracy of the positioning pin 57 adjusted by adjusting the thickness of the washer.

[0052] The auxiliary positioning device II6 has the same structural principle as the auxiliary positioning device I5, the difference being that the positioning pin 57 of the auxiliary positioning device I5 is a round pin, while the positioning pin of the auxiliary positioning device II6 is a diamond-shaped pin.

[0053] During use, after the top cover is placed on the transfer device, the handle 52 is pressed and the positioning pin 57 is raised. Since the top cover is relatively long in the Y direction, the plate is prone to Y-direction movement. The positioning pin 57 plays an auxiliary positioning role.

[0054] After the stamping process of the top cover is completed, the device of this invention places the top cover on the positioning frame 2. The rear positioning hole falls into the round pin of the rear limiting and positioning device 9. Pressing the handle 52 of the auxiliary positioning device I 5 and the auxiliary positioning device II 6 causes the luggage rack mounting hole of the top cover to fall into the positioning pin 57 of the auxiliary positioning device I 5 and the auxiliary positioning device II 6, which serves as a limiting function in the X and Y directions. The rocker arms of the front flip Z-direction protection device 7 and the rear flip Z-direction protection device 8 are lowered to provide Z-direction protection.

[0055] Forklifts load the device into box-type logistics transfer vehicles for transport to the welding workshop. The same applies to forklifts unloading the device along with its top cover and transporting it to the welding workshop's logistics area. An electric tractor connects to the device's traction device and transports it to the workstation. The rear traction device can connect to subsequent transfer devices for delivery to the workstation. After being manually pushed to the laser room's precision positioning port on the top cover, the front and rear flip-Z-axis protective devices are opened. The handles of auxiliary positioning devices I5 and II6 are pressed to lower the auxiliary positioning pins. A robot carrying a top cover gripper then picks up the top cover for assembly and welding.

[0056] The front-mounted Z-axis protective device 7 includes a connecting plate 71, a pin 72, a plunger 73, a rocker arm 74, a gasket 75, a positioning block 76, and a limiting block 77. The connecting plate 71 connects the pin 72 and the plunger 73, and the limiting block 77 is welded to it. The rocker arm 74 is mounted on the top of the connecting plate 71, and the positioning block 76 is mounted on the bottom of the rocker arm 74. A gasket 75 is provided at the connection between the rocker arm 74 and the positioning block 76. The positioning block 76 is made of polyurethane and conforms to the shape of the surface at the contact position with the product. During transportation, the positioning block 76 is the contact surface with the top cover, effectively preventing the sheet metal surface from being bumped. The limiting block 77 is welded to the connecting plate 71 to prevent the rocker arm 74 from tilting too low during use and bumping into the top cover.

[0057] The rear flip-over Z-axis protective device 8 has the same structural principle as the front flip-over Z-axis protective device 7. The positioning block conforms to the product shape, and the structures of other components are the same. It also includes a rocker arm, positioning block, connecting plate, pin, gasket, plunger, and limit block. The positioning block is made of polyurethane material. During transportation, the positioning block is the contact surface with the top cover, effectively preventing the sheet metal surface from being bumped.

[0058] The front flip-over Z-axis protective device and the rear flip-over Z-axis protective device, during the use of the device, after the top cover is placed on the device, manually flip the rocker arm to play a Z-axis protective role.

[0059] The rear limiting and positioning device 9 includes a support 91, a pin seat 92, a positioning pin 93, three sets of gaskets 94, two positioning blocks 95, four connecting blocks 96, gasket labels 97, and component labels 98. The positioning blocks 95 are made of high-density nylon material, which prevents collisions with metal parts and increases wear resistance. The positioning pins 93 ensure the top cover's accuracy in the Y direction of the device.

[0060] The support 91 is a welded structure, and the pin seat 92 is fixed to the support 91 by screws; the positioning pin 93 is fixed to the pin seat 92 by screws; the three sets of washers 94 are fixed between the positioning block 95 and the connecting block 96 by screws; the positioning block 95 is fixed to the connecting block 96 by screws; the connecting block 96 is fixed to the support 91 by screws; the washer label 97 is fixed to the connecting block 96 by rivets; and the component label 98 is fixed to the support 91 by rivets.

[0061] The rear limiting and positioning device 9, with its two positioning pins 93 on the left and right, ensures accurate positioning of the top cover in the Y and X directions and accurate support of the Z-direction profile on the device of this invention.

[0062] The rear traction device 10 includes a connecting hook 101, a welded component 102, and a pin 103. The rear traction device 10 includes a connecting hook 101, a welded component 102, and a pin 103; the connecting hook 101 is welded and fixed to the top of the welded component 102, and the pin 103 is installed at the bottom of the welded component 102.

[0063] This invention can manufacture multiple units for transfer and positioning in stamping and welding workshops. The front traction device 3 of this invention can be connected to an internal electric tractor, or the front traction device 3 and the rear traction device 10 of this invention can be connected to achieve the transportation of multiple units of this invention together.

[0064] In practical use, the transfer frame 1 and the precision positioning port of the production line are designed to match and are used in a fixed structure. The roofs of different vehicle models can be flexibly used by switching between the overall positioning frame 2 or the contour support positioning block 23 and the intermediate support positioning block.

[0065] The device of this invention can be transferred in the stamping and welding workshop to complete the single-piece conveying of the top cover. It serves as a transfer tool, a precision positioning device for entering the precision positioning port, and also functions as an inspection tool.
