Description

Technical Field

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

[0002] The quality and packaging integrity of the tailgate left hinge seat plate group are crucial to the subsequent vehicle assembly and performance. The existing tailgate left hinge seat plate group packaging equipment workflow covers multiple links. First, the loading link adopts a vibrating disc loader or a manual loading platform, and 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 group 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 qualified packaged tailgate left hinge seat plate group products are transported to the palletizing area through the 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, the existing intelligent packaging equipment has certain problems when conveying and labeling the packaged boxes. In order to ensure the stability of labeling and printing, baffles need to be set on both sides of the conveyor on the packaging boxes. Since the number of back door left hinge seat plate groups installed in different packaging boxes is different, the sizes of packaging boxes are different. At this time, it is troublesome to frequently adjust the baffles to adapt to packaging boxes of different sizes. Moreover, when the production plan requires to ensure the consistency of the output quantity of large and small packaging boxes and adopts a production scheduling plan of staggered packaging of large and small sizes, the limitations of the existing baffle adjustment mechanism are more prominent. Even after adjustment, the baffles are difficult to meet the limiting requirements of packaging boxes of various sizes at the same time. During the conveying process, small-sized packaging boxes are prone to shaking and offset in the channel, and large-sized packaging boxes 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 and labeling printing effect.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 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 arc conveyor belt, and the limiting conveying components at the top of the supporting plates are operated in coordination, so that the four corners of the packaging box can be positioned and conveyed. Compared with the cumbersome operation of the traditional baffle plate that needs to be frequently adjusted to adapt to packaging boxes of different sizes, the intelligent packaging equipment can automatically adapt to packaging boxes of various sizes when in use. Regardless of whether the size is staggered, the packaging box equipped with the left hinge seat plate group of the back door can be accurately positioned and limited for conveying, ensuring that the packaging box remains centered and stable during the conveying process to avoid deviation, thereby improving the stability and accuracy of the subsequent labeling and printing. At the same time, during the positioning and conveying, only the four corners of the packaging box are in contact, which greatly reduces the friction area with the surface of the box, effectively reduces the wear on the surface of the box, and ensures the subsequent conveying labeling and printing effect. Frequent manual adjustment is not required, thereby improving the working efficiency and automation of the packaging equipment. 2. When the intelligent packaging equipment for the left hinge seat plate group of the rear door is in use, through the setting of the spray activation component, when the packaging box is positioned and conveyed, the spray activation component is automatically triggered to start, and the diluted surfactant solution is evenly sprayed on the surface of the packaging box. Surfactant molecules have the characteristics of hydrophilicity and lipophilicity, which can reduce the surface tension of the packaging box surface, significantly improve its surface wettability. The surfactant solution can penetrate into the gaps between paper fibers, enhance the bonding force between fibers, ink, and glue, improve its surface polarity, and increase the adsorption capacity for materials such as glue, ensuring the effect of subsequent labeling and printing. At the same time, through the setting of the micro-current component, when the spray activation component finishes working, the micro-current component is automatically triggered to turn on, applying a weak current to the surface of the packaging box, which will cause the molecules on the surface of the paper box to move directionally, changing the microscopic structure and charge distribution on the surface. 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. At the same time, the micro-current 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.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Example 1, please refer to Figure 1 - Figure 5 , a packaging device for the left hinge seat plate group of a rear door, including a ring conveyor belt 2, a mounting frame 1 fixed at the bottom end of the ring conveyor belt 2, and an intelligent packaging mechanism 3 fixed at the top end of the mounting frame 1. A plurality of limit seats 5 are fixedly arranged at equal intervals around the top end of the ring conveyor belt 2. Support plates 4 are fixedly installed at the top ends of the plurality of limit seats 5, and a limit conveying component is arranged at the top end of each support plate 4; The limit conveying component includes four slide blocks 8 and four positioning blocks 11. The four slide blocks 8 are sequentially arranged at the four corners of the top end of the support plate 4, and the four positioning blocks 11 are sequentially fixedly installed outside the top ends of the four slide blocks 8.

[0020] When viewed from above, the four positioning blocks 11 are all L-shaped. Sponge sheets 12 are adhesively fixed on the inner walls of the four positioning blocks 11. Chutes 7 are correspondingly penetrated and arranged inside the support plate 4 near the four slide blocks 8. Each slide block 8 is slidably engaged and installed inside the chute 7 on the corresponding side. An electric telescopic rod 6 is fixedly installed through the inside of the limit seat 5.

[0021] The output end of the electric telescopic rod 6 is fixedly installed with one side of one of the slide blocks 8. A rectangular block 9 is rotatably engaged and installed through the outside of one side of the limit seat 5. Pull rods 10 are rotatably installed at the corners of the rectangular block 9. One end of each pull rod 10 is rotatably installed with one of the slide blocks 8 on the corresponding side. The pull rod 10 is L-shaped.

[0022] In this embodiment, when the intelligent packaging device for the left hinge seat plate group of the rear door is in use, first, the packaging cartons are sequentially placed on the tops of several supporting plates 4 through an existing carton picking device. When the packaging cartons are placed on the tops of the supporting plates 4, the existing annular conveyor belt 2 is started to sequentially convey the supporting plates 4 and the packaging boxes placed at their bottoms. During the conveying process, the electric telescopic rod 6 at the bottom of the supporting plate 4 can be controlled to contract. Through the contraction of the output end of the electric telescopic rod 6, one of the sliders 8 on one side is driven to move inside the chute 7. At this time, through the through-rotation installation of the rectangular block 9 and the limiting seat 5, and the arrangement of the 7-shaped pull rod 10, when the electric telescopic rod 6 pulls one of the sliders 8 to move centrally, the remaining three sliders 8 will be driven to move centrally synchronously. Through the central movement of the four sliders 8, the corresponding positioning blocks 11 at the top are driven to move centrally synchronously. Through the L-shaped arrangement of the positioning blocks 11, after the four positioning blocks 11 move centrally, the four corners of the packaging box can be positioned. At the same time, through the arrangement of the sponge sheets 12 on the inner walls of the positioning blocks 11, when the four corners of the packaging box are positioned, it can play a certain role in buffering and protecting. After the positioned packaging box is conveyed to the bottom of the intelligent packaging mechanism 3, the annular conveyor belt 2 stops running. At this time, through the existing intelligent packaging mechanism 3, multiple left hinge seat plate groups of the rear door are placed into the packaging box in sequence. After the placement is completed, the annular conveyor belt 2 continues to run and convey. When this device is in use, it can position and convey the four corners of the packaging box. Compared with the traditional baffle that needs to be frequently adjusted to adapt to different sizes of packaging boxes, this intelligent packaging device can automatically adapt to various sizes of packaging boxes during use. Whether it is staggered packaging in terms of size or not, it can accurately position and limit the conveyance of the packaging box containing the left hinge seat plate group of the rear door, ensuring that the packaging box remains centered and stable during the conveyance process, avoiding deviation, and improving the stability and accuracy of subsequent labeling and printing. As Figure 5 shown, and at the same time, during the positioning and conveyance, it only contacts the four corners of the packaging box, greatly reducing the friction area with the surface of the box body, effectively reducing the wear on the surface of the box body, ensuring the subsequent conveyance, labeling, and printing effects, and eliminating the need for frequent manual adjustment, improving the working efficiency and automation degree of the packaging equipment, and having a good overall use effect.

[0023] Example 2, please refer to Figure 6 - Figure 10 , this embodiment further explains Example 1. A spray activation component and a microcurrent component are arranged on the outer side of the bottom of each supporting plate 4 near two sliders 8; the spray activation component includes a fixed seat 16 and a liquid collection cylinder 17. The fixed seat 16 is fixedly installed on the outer side of the bottom of the supporting plate 4, and the liquid collection cylinder 17 is fixedly installed on the outer side of the fixed seat 16.

[0024] An arc-shaped resistance block 14 is symmetrically arranged on the outside of one side of the top end of the endless conveyor belt 2, and an auxiliary frame 13 is fixedly installed on the bottom end of the resistance block 14. One end of the auxiliary frame 13 is fixedly installed on the outside of one side of the mounting frame 1, and an arc-shaped conduction block 15 is fixedly arranged on the top end of the resistance block 14.

[0025] A piston rod 18 is installed inside the liquid collecting cylinder 17 in a sliding and sealing manner. A limit block 19 is fixedly installed at one end of the piston rod 18 away from the liquid collecting cylinder 17. A resisting roller 20 is rotatably engaged with the outside of one side of the limit block 19. A limit frame 21 is fixedly installed on the top of the limit block 19.

[0026] 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. Both ends of the reset spring 23 are fixedly installed on one side of the fixed seat 16 and the limiting frame 21 respectively.

[0027] A liquid storage barrel 24 is fixedly installed on one 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 one side of the liquid storage barrel 24, and 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.

[0028] Two one-way liquid discharge valve tubes 28 are symmetrically penetrated and fixed inside the liquid collecting cylinder 17 on one side close to the one-way liquid inlet valve tube 25, and the output ends of the two one-way liquid discharge valve tubes 28 are connected and fixed with spring tubes 27, and one end of the spring tubes 27 is connected and fixed with a conducting tube 26, which is longitudinally fixedly installed on the outside of one side of the positioning block 11 on the corresponding side, and a plurality of atomizing nozzles 29 are embedded and fixed at equal intervals on the outside of the two side ends of the positioning block 11, and the input ends of the plurality of atomizing nozzles 29 are connected and fixed to the inside of one side of the conducting tube 26 on the corresponding side.

[0029] The microcurrent component includes a support seat 33 and a conductive ball 35. The support seat 33 is fixedly installed on the outside of one 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. A number of arc-shaped conductive sheets 30 are evenly fixedly installed 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 fixed to one side of the connecting sheet 31, and one end of the connecting sheet 31 is conductively connected to a wire 32.

[0030] The other end of the wire 32 is connected and fixed to the top side of the conductive ball 35, one end of the conductive ball 35 is fixedly installed with a spring insulating rod 34, the other end of the spring insulating rod 34 is fixedly installed on the outside of one side of the support seat 33, and a label printing component 36 is fixed on the outside of the top side of the mounting frame 1 close to the endless conveyor belt 2.

[0031] In this embodiment, when the packaging box with the left hinge seat plate group of the rear door is conveyed away from the bottom of the intelligent packaging mechanism 3 by the annular conveyor belt 2 and conveyed to the bottom of the label printing assembly 36 for final label printing, when the annular conveyor belt 2 drives the positioned packaging box for conveying, at this time, the contact rollers 20 at both sides of the bottom end of the supporting plate 4 will contact one side of the contact blocks 14 installed on both sides of the auxiliary frame 13. With continuous conveying, the contact rollers 20 will undergo a compression movement due to the change in the slope of the contact blocks 14. When the contact rollers 20 are compressed by force, they will drive the limit block 19 and the piston rod 18 fixed on one side to move synchronously, causing the piston rod 18 to perform a squeezing movement 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, compressing the return spring 23. When the piston rod 18 performs a squeezing movement, it will squeeze the pre-pumped existing surfactant solution inside the liquid collecting cylinder 17 into the internal of the one-way drain valve pipe 28. Then, through the connection and conduction of the spring pipe 27 and the conduction pipe 26, the surfactant solution is evenly and slightly sprayed around the surface of the packaging box through a number of atomizing nozzles 29. Thus, when the packaging box is positioned and conveyed, the spray activation assembly is automatically triggered and started, and the diluted surfactant solution is evenly sprayed on the surface of the packaging box. Surfactant molecules have hydrophilic and lipophilic properties, which can reduce the surface tension of the packaging box surface, significantly improve its surface wettability. The surfactant solution can penetrate into the gaps between the paper fibers, enhance the bonding force between the fibers and the ink and glue, can improve its surface polarity, and improve the adsorption capacity for materials such as glue, ensuring the effect of subsequent label printing.

[0032] It should also be noted that when the contact roller 20 contacts the contact block 14 and moves halfway, the surfactant solution extrusion spraying is completed at this time. At this time, the conduction ball 35 at one end of the spring insulating rod 34 contacts the conduction block 15 externally connected to the top end of the contact block 14. At the same time, with the cooperation of the conduction of the conductive sheet 30 and the wire 32, a microcurrent is generated in several connecting sheets 31 on the side of the positioning block 11. At the same time, with the arc-shaped setting of the pair of connecting sheets 31, one side of the connecting sheet 31 can have a certain elastic contact performance, so that it can stably contact the surface of the packaging box, thereby applying a weak current to the surface of the packaging box. When the microcurrent processes the surface of the paper box, it will cause the molecules on the surface of the paper box to move directionally, changing the microscopic structure and charge distribution on the surface. 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 the microcurrent treatment can also attract the charged particles in the ink and glue, prompting them to move towards the surface of the paper box, further improving 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.

[0033] It should also be noted that when the contact roller 20 separates from the contact block 14, the originally compressed return spring 23 starts to rebound at this time. Through the rebound of the return spring 23, the side limit rod 22, the limit frame 21, the contact roller 20, the limit block 19, and the piston rod 18 are driven 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, with the conduction and fixation of the one-way liquid inlet valve pipe 25 and the liquid storage barrel 24, a certain amount of the surfactant solution previously stored inside the liquid storage barrel 24 is re-extracted and enters the inside of the liquid collection cylinder 17, thereby completing the automatic injection, and the whole can be recycled.

[0034] It should also be noted that when the packaging box equipped with the left hinge seat plate group of the back door passes through the labeling and printing assembly 36 for labeling and printing, the annular conveyor belt 2 is started to convey the packaged finished product. After being conveyed to a certain position, the electric telescopic rod 6 at the bottom end of the supporting plate 4 can be controlled to extend. Through the extension of 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 chute 7. At this time, through the through-rotating installation of the rectangular block 9 and the limit seat 5, and the setting of the 7-shaped pull rod 10, the remaining three sliders 8 are driven to move synchronously and centrally when the electric telescopic rod 6 extends. Through the synchronous expansion of the four sliders 8, the packaging box at the top loses its limit. Then, according to the preset stacking rules, the products are neatly stacked on the tray by the palletizing robot to complete the overall packaging and conveying.
