Description

Technical Field

[0001] The present invention relates to the technical field of cargo box processing, and particularly relates to an automatic sequential welding device for cargo box door panels. Background Art

[0002] As a key component for a vehicle to load goods, the design and function of a cargo box vary depending on the vehicle type and usage. The box door panel of the cargo box is an important part to ensure convenient and safe loading and unloading of goods. When the box door panel is opened, it provides a larger opening for easy loading and unloading of goods; when closed, it can effectively prevent the goods from falling or being stolen. The box door panel usually consists of a door panel and a panel frame. This structure not only facilitates the combination with the cargo box but also ensures its own structural strength. During the production process, the box door panel is welded and fixed to the panel frame through a welding device.

[0003] Currently, the production of box door panels mainly uses a sequential welding device to perform two welding operations. The first welding is spot welding the door panel and the panel frame to ensure the fixed connection of the main structure; the second welding is full welding the door panel and the panel frame to enhance the structural stability and strength. However, there are some deficiencies in the existing welding device during the first welding operation:

[0004] 1. During the first welding, the operator needs to manually extract and place the door panel and the panel frame on the welding table in sequence. This manual feeding method is not only inefficient and unable to guarantee the timeliness of the operation, but also requires position correction after placement to ensure the accurate alignment of the door panel and the panel frame. This not only increases the workload of the operator but also may lead to unstable welding quality.

[0005] 2. After the door panel and the panel frame are placed, the operator also needs to operate the positioning parts on the welding table in sequence to make them enter the positioning state of the door panel and the panel frame. This manual positioning operation not only reduces the automation performance of the device but also significantly affects the operation process, resulting in a decrease in production efficiency.

[0006] In summary, the existing box door panel welding device has obvious deficiencies in the feeding and positioning links, affecting production efficiency and welding quality. Therefore, there is an urgent need for a welding device that can automatically feed and position. Summary of the Invention

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1

[0034] To solve the technical problems in the background art, the following automatic row welding equipment for the cargo box door panel is provided:

[0035] Combined with Figures 1 - 7 As shown, an automatic row welding equipment for the cargo box door panel provided by the present invention includes a support structure 1 and a welding mechanism 2. The welding mechanism 2 is installed above the support structure 1. A guiding component 5 is assembled at the top of the support structure 1. An installation frame 4 is assembled on the support structure 1 through the guiding component 5. Two groups of positioning components 7 are assembled at the top of the installation frame 4. The installation frame 4 positions and clamps a box board 8 through the positioning components 7, and the welding mechanism 2 welds the box board 8. A material lifting mechanism 6 is assembled at the front side inside the support structure 1, and the support structure 1 is used to extract the un-welded box board 8.

[0036] The material lifting mechanism 6 includes a material guiding component 61, a flipping component 62, and a material lifting component 63. The material guiding component 61 is assembled at the front side inside the support structure 1. The flipping component 62 is assembled at the bottom of the material guiding component 61. The material lifting component 63 is assembled on the guiding part of the flipping component 62, and the material lifting component 63 extends out of the material guiding component 61. The positioning component 7 includes a first positioning part 71 and a second positioning part 72. Two groups of second positioning parts 72 are slidably installed inside the installation frame 4. The second positioning parts 72 are used for longitudinal positioning. The first positioning part 71 is assembled on the installation frame 4 inside the second positioning parts 72. The first positioning part 71 is used for lateral positioning.

[0037] In the above solution:

[0038] Through the guiding component 5 on the support structure 1, the mutual cooperation with the installation frame 4 is realized, and the automatic feeding of the installation frame 4 is achieved, so that the placed carriage board structure can be quickly fed below the welding component.

[0039] Through the positioning component 7 inside the installation frame 4, the separate positioning of the box board and the board frame can be quickly completed. And the positioning component 7 adopts an opposed split-type positioning. It can not only complete the opposed constraint on the box board, but also separately position the box board and the board frame, ensuring that the welding states of the box board and the board frame are synchronously positioned, and ensuring that no additional fixed auxiliary positioning is required for subsequent welding.

[0040] The corresponding extraction of the box board 8 and the board rack 81 is realized through the material lifting mechanism 6. The mechanism can switch its own extraction state according to the actual operation process, realizing the automatic classification extraction of the box board 8 and the board rack 81. This not only ensures the welding process of the device but also reduces the labor cost, eliminating the need for multiple personnel to cooperate in feeding;

[0041] During daily operations:

[0042] Start the material guiding component 61 to rise to the extraction state, and then start the flipping component 62 inside the material guiding component 61, prompting the flipping component 62 to flip out from the material guiding component 61. In this way, the material lifting component 63 on the flipping component 62 can enter the working state. The material lifting component 63 first moves above the box board 8 and extracts it, and then with the cooperation of the flipping component 62, it moves it to the top of the material guiding component 61, and with the assistance of the material guiding component 61, the box board 8 is received. Then, the flipping component 62 is used to rotate and switch the angle of the material lifting component 63, prompting the extraction end of the material lifting component 63 to switch to the opposite state. The purpose is to extract the board rack on the other side of the support structure 1 and place the board rack 81 above the box board 8 in the above-mentioned manner. Immediately, the box board and the board rack are positioned by the first positioning component 71 and the second positioning component 72 inside the installation frame 4. At this time, the material guiding component 61 can descend to release the support for the box board 8. Through the cooperation of the installation frame 4 and the guiding component 5, the positioned box board structure can be moved to the welding station for welding.

[0043] Embodiment 2

[0044] As Figure 1 and Figure 7 shown, on the basis of the above embodiment, this embodiment further gives the following content:

[0046] During this period, there are five groups of guide frames 27. A welding head 24 used in cooperation is assembled on each guide frame 27.

[0048] The support assembly 3 cooperates with the box plate assembly to be welded for support. The purpose is to support the box plate 8 to be welded, so that the box plate 8 fits with the plate frame 81 on the top surface, and to ensure that the welding position will not cause the welding to fail due to the gap between the box plate 8 and the plate frame 81 on the top surface;

[0049] During this period, start the sixth telescopic cylinder 33 to support the top seat 34, so as to support the box plate by the top seat 34 and make the box plate fit with the plate frame. The fitting position is the welding position. After spot welding at this position, the sixth telescopic cylinder 33 can be driven to descend, and the sixth telescopic cylinder 33 can be driven to slide through the electric slide rail 32, slide to the position of another welding point, and lift the support again to realize the welding between the box plate and the plate frame.

An installation opening 616 is arranged on the top of the top plate 613, and the installation opening 616 is located on both sides of the installation groove 614. Fixed plates 617 are fixedly installed on both sides of the bottom of the top plate 613, and the flipping assembly 62 is assembled inside the fixed plates 617.

[0051] During this period, when the device is loading, the second telescopic cylinder 612 can be started, and the second telescopic cylinder 612 lifts the top plate 613 and the guide wheel 615 in the installation groove 614. At this time, the receiving surface is higher than the supporting structure 1, and is currently waiting for the introduction of the box plate 8;

[0052] When the box plate 8 is introduced above the top plate 613, it will be supported and guided by the cooperation of the guide wheel 615.

[0053] The flip assembly 62 includes a first motor 621, a mounting frame 622, a slide bar 623, a first screw rod 624, a guide block 625, a second motor 626, a first mounting seat 627, an electric rotary cylinder 628, and a support column 629. The first screw rod 624 and the slide bar 623 are butt-jointedly mounted between the fixed plates 617. The guide block 625 is mounted on the first screw rod 624 and the slide bar 623.

[0056] Start the second motor 626. The second motor 626 drives the mounting frame 622 and the support column 629 to turn, causing the mounting frame 622 and the support column 629 to turn above the top plate 613 and enter the working state. When in the non-working state, the mounting frame 622 and the support column 629 turn down below the top plate 613. When the top plate 613 turns to the upper side, start the third motor 636. The third motor 636 drives the second lead screw 635 to rotate, realizing the driving of the guide plate 634. At this time, the guide plate 634 extends outward from the mounting frame 622, causing the extraction point to move. When reaching the extraction point, start the third telescopic cylinder 633 to drive the mounting plate 631 to descend, causing the electromagnet 632 at the bottom of the mounting plate 631 to adsorb the box plate 8, completing the extraction. And then drive the adsorbed box plate 8 to be recycled through the above method again, and tow the box plate to directly above the top plate 613.

[0057] When the plate frame 81 is being extracted, the mounting frame 622 is driven by the electric rotary cylinder 628 to rotate and switch the orientation, and then operate again according to the above operation process, extract the plate frame 81 above the box plate 8 and lower it, waiting for positioning, conveying and welding.

[0058] During this period, the box plate 8 and the plate frame 81 to be welded are stacked on both sides of the support structure 1 respectively, ensuring that the positions of the workpieces meet the extraction requirements and ensuring the stable extraction of the device.
