Description

Technical Field

[0001] The present invention relates to the technical field of workshop conveying equipment, in particular to a packaging device for a back door left hinge seat plate group. Background Art

[0002] The tailgate left hinge seat plate assembly is a key component for connecting the tailgate of a car. Its quality and packaging integrity are crucial to the subsequent assembly and performance of the entire vehicle. The existing tailgate left hinge seat plate assembly packaging equipment workflow covers multiple links. First, a vibrating disc loader or a manual loading platform is used for loading. Then, the formed packaging box is transported to the bottom of the intelligent packaging mechanism by a conveyor. Then, the tailgate left hinge seat plate assembly is placed into the packaging box in sequence by the intelligent packaging mechanism. After packaging, it is conveyed again. The equipment will automatically mark and inspect the packaged products. Finally, the packaged tailgate left hinge seat plate assembly products that have passed the inspection are transported to the palletizing area through a unloading conveyor belt. The palletizing robot stacks the products neatly on the pallet according to the preset palletizing rules to complete the overall packaging and transportation.

[0003] However, existing intelligent packaging equipment has certain problems when conveying and labeling packaged boxes. In order to ensure the stability of labeling and printing, baffles need to be set on both sides of the conveyor at the package boxes. Since different packages contain different numbers of back door left hinge seat plate groups, the sizes of the packages are different. At this time, it is troublesome to frequently adjust the baffles to adapt to packages of different sizes. Moreover, when the production plan requires to ensure the output quantity of large and small packages is consistent and a production scheduling plan of staggered packaging of large and small sizes is adopted, the limitations of the existing baffle adjustment mechanism are more prominent. Even after adjustment, the baffles are difficult to meet the limit requirements of packages of various sizes at the same time. During the conveying process, small-sized packages are prone to shaking and offset in the channel, and large-sized packages may be stuck due to insufficient clearance, resulting in a significant decrease in conveying efficiency and even causing production line failure. In addition, the contact and friction between the baffle and the surface of the box will cause wear on the surface of the box, thereby affecting the subsequent conveying, labeling and printing effects.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. When the left-hinge seat plate group intelligent packaging equipment for the back door is in use, multiple supporting plates are arranged on the curved conveyor belt, and the limiting conveying assembly at the top of the supporting plates is operated in coordination, so that the four corners of the packaging box can be positioned and conveyed. Compared with the tedious operation of traditional baffles that need to be frequently adjusted to adapt to packaging boxes of different sizes, this intelligent packaging equipment can automatically adapt to packaging boxes of various sizes when in use. Regardless of whether large and small boxes are staggered, the packaging box equipped with the left-hinge seat plate group for the back door can be accurately positioned and limited for conveying, ensuring that the packaging box remains centered and stable during the conveying process, avoiding deviation, and improving the stability and accuracy of subsequent labeling and printing. At the same time, during positioning and conveying, it only contacts the four corners of the packaging box, greatly reducing the friction area with the box surface, effectively reducing the wear on the box surface, ensuring the effect of subsequent conveying, labeling and printing, and eliminating the need for frequent manual adjustments, thereby improving the working efficiency and automation of the packaging equipment.

[0017] 2. When the left hinge seat plate group intelligent packaging equipment of the back door is in use, the spray activation component is set. When the packaging box is positioned and transported, the spray activation component is automatically triggered to start and the diluted surfactant solution is evenly sprayed on the surface of the packaging box. The surfactant molecules have hydrophilic and lipophilic properties, which can reduce the surface tension of the packaging box surface and significantly improve the wettability of the surface. The surfactant solution can penetrate into the gaps of the paper fibers, enhance the bonding force between the fibers and the ink and glue, improve the polarity of the surface, and improve the adsorption capacity of materials such as glue to ensure the subsequent labeling and printing. It has the effect of a brush. At the same time, through the setting of the microcurrent component, when the spray activation component completes its work, the microcurrent component is automatically triggered to turn on and apply a weak current to the surface of the packaging box, which will prompt the molecules on the surface of the paper box to move in a directional manner and change the surface microstructure and charge distribution. In this way, the subsequent sprayed ink, glue and other material molecules are more likely to attract each other with the molecules on the surface of the paper box, creating better conditions for the formation of chemical bonds or intermolecular forces, thereby enhancing the adhesion effect. At the same time, the microcurrent also has a certain bactericidal effect, which can inhibit the growth of bacteria on the surface of the packaging box, and the overall packaging and conveying effect is better.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1, please refer to Figure 1 - Figure 5 A packaging device for a back door left hinge seat plate group includes an endless conveyor belt 2, a mounting frame 1 fixed to the bottom end of the endless conveyor belt 2, and an intelligent packaging mechanism 3 fixed to the top of the mounting frame 1. A plurality of limit seats 5 are fixedly arranged around the top of the endless conveyor belt 2 at equal intervals. A supporting plate 4 is fixedly installed on the top of each of the limit seats 5. A limiting conveying component is provided on the top of each of the supporting plates 4; the limiting conveying component includes four sliders 8 and four positioning blocks 11. The four sliders 8 are sequentially arranged at the four corners of the top of the supporting plate 4, and the four positioning blocks 11 are sequentially fixedly installed on the outside of the top of the four sliders 8.

[0031] The four positioning blocks 11 are all L-shaped when viewed from above, and sponge pieces 12 are adhered and fixed to the inner walls of the four positioning blocks 11. The support plate 4 is provided with corresponding sliding grooves 7 near the inside of the four sliders 8. Each slider 8 is slidably engaged and installed in the sliding groove 7 on the corresponding side, and an electric telescopic rod 6 is fixedly installed inside the limit seat 5.

[0032] The output end of the electric telescopic rod 6 is fixed to one side of one of the sliders 8, and a rectangular block 9 is installed on the outside of one side of the limit seat 5 for rotation and engagement. Pull rods 10 are rotatably installed at the corners of the rectangular block 9, and one end of the pull rod 10 is rotatably installed with one of the sliders 8 on the corresponding side, and the pull rod 10 is arranged in a 7 shape.

[0033] When the packaging box is placed on the top of the supporting plate 4, the existing endless conveyor belt 2 is started to convey the supporting plate 4 and the packaging boxes placed on the bottom thereof in sequence. During the conveying, the electric telescopic rod 6 at the bottom of the supporting plate 4 can be controlled to retract. Through the retraction of the output end of the electric telescopic rod 6, one of the sliders 8 on one side can be driven to move inside the slide groove 7. At this time, the rectangular block 9 and the limit seat 5 are rotated through the installation, and the 7-shaped pull rod 10 is set, so that when the electric telescopic rod 6 pulls one of the sliders 8 to move in the center, the remaining three sliders 8 will be driven to move in the center synchronously. Through the centering movement of the four sliders 8, the corresponding positioning block 11 at the top is driven to move in the center synchronously. Through the L-shaped setting of the positioning block 11, the four positioning blocks 1 After the positioning block 1 is moved to the center, the four corners of the packaging box can be positioned. At the same time, the sponge sheet 12 on the inner wall of the positioning block 11 can play a certain role in buffering and protecting when positioning the four corners of the packaging box. After the positioned packaging box is transported to the bottom of the intelligent packaging mechanism 3, the endless conveyor belt 2 stops running. At this time, multiple back door left hinge seat plate groups are placed into the interior of the packaging box through the existing intelligent packaging mechanism 3. After the placement is completed, the endless conveyor belt 2 continues to run and transport. This device can position and transport the four corners of the packaging box when in use. Compared with the cumbersome operation of traditional baffles that require frequent adjustment to adapt to packaging boxes of different sizes, this intelligent packaging equipment can automatically adapt to packaging boxes of various sizes when in use. Regardless of whether staggered packaging of different sizes is performed, it can accurately position the packaging box equipped with the back door left hinge seat plate group for limited transportation, ensuring that the packaging box remains centered and stable during transportation, avoiding deviation, and improving the stability and accuracy of subsequent labeling and printing. Figure 5 As shown, during positioning and transportation, it only contacts the four corners of the packaging box, greatly reducing the friction area with the box surface, effectively reducing the wear on the box surface, ensuring the subsequent transportation, labeling and printing effects, and eliminating the need for frequent manual adjustments, thereby improving the working efficiency and automation level of the packaging equipment and achieving good overall use effects.

[0034] Example 2, please refer to Figure 6 - Figure 10This embodiment further explains Example 1. A spray activation component and a microcurrent component are provided on the outside of the bottom side of the support plate 4 near each of the two sliders 8; the spray activation component includes a fixed seat 16 and a liquid collecting cylinder 17. The fixed seat 16 is fixedly installed on the outside of the bottom side of the support plate 4, and the liquid collecting cylinder 17 is fixedly installed on the outside of one side of the fixed seat 16.

[0035] An arc-shaped interference block 14 is symmetrically arranged on the outside of one side of the top of the endless conveyor belt 2, and an auxiliary frame 13 is fixedly installed on the bottom end of the interference block 14. One end of the auxiliary frame 13 is fixed to the outside of one side of the mounting frame 1, and an arc-shaped conductive block 15 is fixed on the top end of the interference block 14.

[0036] A piston rod 18 is installed in a sliding and sealing manner inside the liquid collecting cylinder 17, and a limit block 19 is fixedly installed on the end of the piston rod 18 away from the liquid collecting cylinder 17. A resistance roller 20 is rotatably engaged with the outside of one side of the limit block 19, and a limit frame 21 is fixedly installed on the top of the limit block 19.

[0037] A limiting rod 22 is fixedly installed on one side of the limiting frame 21 close to the fixed seat 16. One end of the limiting rod 22 is slidably installed on the outside of one side of the fixed seat 16. A reset spring 23 is sleeved through the outside of the limiting rod 22. The two ends of the reset spring 23 are respectively fixed on one side of the fixed seat 16 and the limiting frame 21.

[0038] A liquid storage barrel 24 is fixedly installed on the side of the supporting plate 4 close to the liquid collecting cylinder 17, and a one-way liquid inlet valve tube 25 is fixedly installed through the inside of one side of the liquid storage barrel 24. The output end of the one-way liquid inlet valve tube 25 is installed through the inside of the side of the liquid collecting cylinder 17 away from the piston rod 18.

[0039] Two one-way liquid discharge valve tubes 28 are symmetrically fixed inside the liquid collecting cylinder 17 on one side close to the one-way liquid inlet valve tube 25. The output ends of the two one-way liquid discharge valve tubes 28 are connected to and fixed with spring tubes 27. One end of the spring tube 27 is connected to and fixed with a conducting tube 26. The conducting tube 26 is longitudinally fixedly installed on the outside of one side of the positioning block 11 on the corresponding side. Several atomizing nozzles 29 are embedded and fixed at equal intervals on the outside of the two side ends of the positioning block 11. The input ends of the several atomizing nozzles 29 are all fixed to the inside of one side of the conducting tube 26 on the corresponding side.

[0040] The microcurrent component includes a support seat 33 and a conductive ball 35. The support seat 33 is fixedly mounted on the outside of the side of the support plate 4 close to the liquid collecting cylinder 17. The conductive ball 35 is arranged on the outside of the top side of the contact roller 20. Several arc-shaped conductive sheets 30 are fixedly installed at equal intervals on the inner walls of the two ends of the positioning block 11. A connecting sheet 31 is embedded and fixed on the outside of one side of the positioning block 11. One end of the conductive sheet 30 is fitted and fixed to one side of the connecting sheet 31, and one end of the connecting sheet 31 is conductively connected to a wire 32.

[0041] The other end of the wire 32 is connected and fixed to the top side of the conductive ball 35. A spring insulating rod 34 is fixedly installed on one end of the conductive ball 35. The other end of the spring insulating rod 34 is fixedly installed on the outside of one side of the support seat 33. A label printing component 36 is fixed on the outside of the top side of the mounting frame 1 near the endless conveyor belt 2.

[0042] In this embodiment, when the packaging box with the left hinge seat plate group of the back door is transported away from the bottom of the intelligent packaging mechanism 3 by the circular conveyor belt 2, and transported to the bottom of the label printing component 36 for the final label printing, the circular conveyor belt 2 drives the positioned packaging box for transportation. At this time, the two sides of the bottom end of the support plate 4 will conflict with the one side of the friction block 14 installed on the auxiliary frame 13 on both sides. As the transportation continues, the friction roller 20 is compressed by the change in the slope of the friction block 14. When the friction roller 20 is compressed, it will drive the fixed limit block 19 and the piston rod 18 on one side to move synchronously, so that the piston rod 18 is squeezed inside the liquid collecting cylinder 17. At the same time, the limit frame 21 at the top of the limit block 19 will also drive the limit rod 22 to move inside the fixed seat 16, so that the return spring 23 is compressed, and the piston rod 18 During the extrusion movement, the existing surfactant solution previously drawn into the liquid collecting cylinder 17 will be squeezed into the one-way discharge valve tube 28, and then connected to the conducting tube 26 through the spring tube 27, so that the surfactant solution is evenly sprayed in small amounts on the surrounding surfaces of the packaging box through several atomizing nozzles 29, so that when the packaging box is positioned and transported, the spray activation component is automatically triggered and started to evenly spray the diluted surfactant solution on the surface of the packaging box. The surfactant molecules have hydrophilic and lipophilic properties, which can reduce the surface tension of the packaging box surface and significantly improve the wettability of its surface. The surfactant solution can penetrate into the gaps of paper fibers, enhance the bonding force between the fibers and ink and glue, improve the polarity of its surface, and improve the adsorption capacity of materials such as glue, thereby ensuring the effect of subsequent labeling and printing.

[0043] It should also be noted that when the friction roller 20 moves halfway to the friction block 14, the extrusion and spraying of the surfactant solution is completed. At this time, the conductive ball 35 at one end of the spring insulating rod 34 conflicts with the external conductive conductive block 15 at the top of the friction block 14, and at the same time, the conductive sheet 30 and the wire 32 are connected, so that the several connecting pieces 31 on the side of the positioning block 11 generate microcurrents. At the same time, the arc setting of the connecting piece 31 pair makes one side of the connecting piece 31 have a certain elastic friction performance, so that it can make stable contact with the surface of the packaging box, thereby applying a weak current to the surface of the packaging box. When the microcurrent treats the surface of the paper box, it will cause the molecules on the surface of the paper box to move in a directional manner, changing the surface microstructure and charge distribution. In this way, the molecules of materials such as ink and glue sprayed subsequently are more likely to attract each other with the molecules on the surface of the paper box, creating better conditions for the formation of chemical bonds or intermolecular forces, thereby enhancing the adhesion effect. Moreover, the weak electric field generated during microcurrent treatment can also attract the charged particles in ink and glue, prompting them to move to the surface of the paper box, further improving the adhesion effect. At the same time, microcurrent also has a certain bactericidal effect, which can inhibit the growth of bacteria on the surface of the packaging box, and the overall packaging and conveying effect is better.

[0044] It should also be noted that when the resistance roller 20 is disengaged from the resistance block 14, the originally compressed return spring 23 begins to rebound, and the rebound of the return spring 23 drives the limit rod 22, the limit frame 21, the resistance roller 20, the limit block 19 and the piston rod 18 on one side to rebound and reset synchronously. When the piston rod 18 rebounds and resets, a certain negative pressure suction effect will be generated. At this time, the one-way liquid inlet valve tube 25 and the liquid storage barrel 24 are connected and fixed, so that a certain amount of surfactant solution stored in the liquid storage barrel 24 in advance is re-extracted into the liquid collecting cylinder 17, thereby completing automatic injection, and the whole can be recycled.

[0045] It should also be noted that after the packaging box equipped with the left hinge seat plate group of the back door is labeled and printed by the label printing component 36, the finished packaged product is transported by starting the circular conveyor belt 2. After being transported to a certain position, the electric telescopic rod 6 at the bottom end of the support plate 4 can be controlled to extend. By extending the output end of the electric telescopic rod 6, one of the sliders 8 on one side is driven to move and reset inside the slide groove 7. At this time, the rectangular block 9 and the limit seat 5 are installed through rotation, and the 7-shaped pull rod 10 is set, so that the extension of the electric telescopic rod 6 drives the remaining three sliders 8 to move synchronously to the center. The synchronous expansion and deployment of the four sliders 8 makes the packaging box at the top lose its limit. Then, the stacking robot stacks the products neatly on the pallet according to the preset stacking rules to complete the overall packaging and transportation.

[0046] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
