Description

Technical Field

[0001] This utility model relates to the field of reflective film conveying technology, and more specifically, to an automatic reflective film conveying device. Background Technology

[0002] Currently, in the production process of semi-finished license plates, a reflective film is applied to their surface. This film reflects light off the license plate, ensuring that the information is clearly visible even in low-light conditions. This design guarantees that drivers can clearly identify the license plate number in both sunlight and darkness, thereby enhancing driving safety.

[0003] Reflective film needs to be stored wrapped in paper tubes. Many rolls of reflective film are needed in the production of semi-finished license plates. Once the previous roll of reflective film is used up, it needs to be replaced. When a batch of reflective film is used up, it needs to be manually transferred a long distance to the reflective film storage area to retrieve it and then returned before it can be installed and put into use. This is labor-intensive, and there is currently a lack of automated batch conveying and transfer equipment for reflective film. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose an automatic reflective film conveying device.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An automatic reflective film conveying device includes a frame, connecting rollers, a turntable, a drive assembly, a telescopic component, a limit block, an insert, a through hole, a clamping assembly, a track-type electric flatcar, a placement box, and a discharge hole.

[0007] The connecting roller is mounted on the frame and one end of the connecting roller is rotatably connected to the center of the turntable.

[0008] The drive assembly is mounted on the frame and connected to the turntable;

[0009] The telescopic component is circumferentially set on the turntable, and the telescopic component's retraction rod passes through the turntable and connects to a limit block;

[0010] The insertion tube is positioned on the limiting block, and the center of the insertion tube and the center of the limiting block are on the same straight line.

[0011] Each cannula has symmetrical through holes;

[0012] The clamping assembly is located inside the insertion tube and mates with the through hole;

[0013] The placement box is set on a track-mounted electric flatbed cart, and the track of the track-mounted electric flatbed cart is on the ground in front of the turntable;

[0014] The bottom side of the placement box has a discharge hole facing one of the insertion tubes.

[0015] Furthermore, the drive assembly employs gear transmission.

[0016] Furthermore, the clamping assembly includes a fixing rod, a miniature electric push rod, and a clamping plate. Each insertion tube is provided with a fixing rod, and miniature electric push rods are symmetrically arranged on the fixing rods. The miniature electric push rods are connected to the clamping plate, and the clamping plate is directly opposite the through hole and cooperates with the through hole.

[0017] The above solution uses a clamping component to hold the reflective film from the inside through the inner hole of the insert tube as it passes through the reflective film paper tube, thereby enabling the automatic transfer of the reflective film from the placement box to the insert tube.

[0018] Furthermore, the clamping plate has an arc shape and a rubber layer on its surface.

[0019] Furthermore, the placement box is equipped with a cylinder, and the cylinder is connected to a baffle that cooperates with the discharge hole.

[0020] The above solution uses a cylinder to drive the baffle to move, which can prevent the reflective film at the bottom from flowing out of the discharge hole during the movement of the track-type electric flat car.

[0021] Furthermore, the track-mounted electric flatbed is equipped with a vision camera.

[0022] When the vision camera detects that there is only one reflective film left on the turntable, it will immediately send a signal to the controller. The controller will then control the tracked electric flatcar to move back to the reflective film storage area to start the next round of automatic conveying and unloading of reflective film.

[0023] Furthermore, the track-type electric flatcar is provided with a limit plate at the initial end of the track, and a rubber block is provided on the limit plate.

[0024] Furthermore, a distance sensor is provided on the limiting plate.

[0025] The above solution uses a limit plate and rubber blocks to limit the movement position of the track-mounted electric flatbed cart. The distance sensor can prevent the two from making hard contact, thereby accurately limiting the movement direction of the track-mounted electric flatbed cart in the area near the turntable.

[0026] Furthermore, a six-degree-of-freedom robotic arm is fitted to one side of the track end of the track-type electric flatcar.

[0027] The above solution uses a six-degree-of-freedom robotic arm to neatly stack the reflective film into the placement box.

[0028] Compared with the prior art, the beneficial effects of this utility model are:

[0029] Compared to existing technologies, this device can automatically complete the batch transfer and conveying process of reflective film. When it is conveyed to one side of the turntable, it automatically transfers it to several insertion tubes in sequence for subsequent replacement and retrieval. Manual transfer of reflective film over long distances is no longer required. The automated conveying effect of reflective film is excellent and significantly reduces the labor intensity of manual transfer. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0036] like Figures 1 to 3 As shown, an automatic reflective film conveying device includes a frame 1, connecting rollers 2, turntable 3, drive assembly 4, telescopic component 5, limiting block 6, insertion tube 7, through hole 8, clamping assembly, track-type electric flatcar 12, placement box 13, and discharge hole 14.

[0037] The connecting roller 2 is mounted on the frame 1 and one end of the connecting roller 2 is rotatably connected to the center of the turntable 3 (the turntable 3 is mounted on one side of the reflective film installation and processing area);

[0038] The drive component 4 is mounted on the frame 1 and connected to the turntable 3 (the drive component 4 uses gear transmission, which is existing technology and its principle will not be described).

[0039] The telescopic component 5 is circumferentially arranged on the turntable 3 and the retraction rod of the telescopic component 5 passes through the turntable 3 and connects to the limit block 6;

[0040] The insertion tube 7 is positioned on the limiting block 6, and the center of the insertion tube 7 and the center of the limiting block 6 are on the same straight line.

[0041] Each cannula 7 has symmetrical through holes 8;

[0042] The clamping assembly is located inside the insertion tube 7 and mates with the through hole 8;

[0043] The placement box 13 is set on the track-mounted electric flatbed cart 12, and the track of the track-mounted electric flatbed cart 12 is on the ground in front of the turntable 3.

[0044] The bottom side of the placement box 13 has a discharge hole 14 facing one of the insertion tubes 7. The size of the discharge hole 14 is equal to the height of a reflective film.

[0045] Further refinements of the embodiments of this utility model, such as... Figure 1 and Figure 2 As shown, the clamping assembly includes a fixing rod 9, a miniature electric push rod 10, and a clamping plate 11. Each insertion tube 7 is provided with a fixing rod 9, and miniature electric push rods 10 are symmetrically arranged on the fixing rod 9. The miniature electric push rods 10 are connected to the clamping plate 11, and the clamping plate 11 is directly opposite to the through hole 8 and cooperates with the through hole 8.

[0046] In a further optimization of the above embodiment, the clamping plate 11 has an arc and a rubber layer on its surface.

[0047] In a further optimization of the embodiment of this utility model, a cylinder 15 is provided on the placement box 13, and the cylinder 15 is connected to a baffle 16 that cooperates with the discharge hole 14.

[0048] A further refinement of the embodiment of this utility model is that a vision camera is provided on the track-type electric flatbed 12.

[0049] In a further optimization of the above embodiment, a six-degree-of-freedom robotic arm is fitted to one side of the track end of the track-type electric flatbed 12. The vision camera and the six-degree-of-freedom robotic arm are both existing technologies and are not modified, and are not shown in the figure.

[0050] It should be noted that the drive assembly 4, telescopic component 5, miniature electric push rod 10, track-type electric flatbed 12, vision camera, and six-degree-of-freedom robotic arm are all electrically connected to the controller, which is not shown in the figure.

[0051] The working process of this utility model:

[0052] In the initial state, the controller controls the track-type electric flatbed cart 12 to move to the end of the track (i.e. the reflective film storage area), and then a number of reflective films (all reflective films are the same size) are neatly stacked into the placement box 13 by a six-degree-of-freedom robotic arm. It should be noted that the left and right side walls of the placement box 13 are in contact with the end face of the reflective film, and the front and rear side walls of the placement box 13 are in contact with the surface of the reflective film.

[0053] After several reflective films are placed into the placement box 13, the cylinder 15 drives the baffle 16 to move and block the discharge hole 14. This can prevent the reflective film at the bottom from flowing out of the discharge hole 14 during the movement of the track-type electric flatcar 12. When the track-type electric flatcar 12 drives the placement box 13 to move to one side of the turntable 3, it stops. Then the cylinder 15 can drive the baffle 16 to release the blockage of the discharge hole 14. At this time, the insertion tube 7 at the bottom of the turntable 3 is directly opposite the inner hole of the reflective film paper tube at the bottom of the placement box 13.

[0054] Then the telescopic component 5 connected to the bottom insertion tube 7 moves independently, thereby driving the insertion tube 7 to be horizontally inserted into the inner hole of the bottom reflective film paper tube. It is preset so that the diameter of the insertion tube 7 is the same as the inner diameter of the reflective film paper tube. When the insertion tube 7 is inserted into the inner hole of the paper tube, the telescopic component 5 stops working. At the same time, the controller controls the micro electric push rod 10 in the current insertion tube 7 to move outward synchronously, thereby clamping the inner wall of the reflective film paper tube through the clamping plate 11. After clamping is completed, the telescopic component 5 retracts, so that the bottom reflective film can move out from the discharge hole 14 and be transferred to the insertion tube 7.

[0055] Then the reflective film moves downward so that the second reflective film paper tube moves to the side of the discharge hole 14. At the same time, the controller controls the drive component 4 to work so that the turntable 3 can rotate. After the rotation is completed, the other insertion tube 7 moves to the position that is directly opposite the inner hole of the second reflective film paper tube. Then the above process is repeated to automatically discharge and transfer the reflective film again.

[0056] Finally, several reflective films are transferred to multiple insertion tubes 7 for storage. When needed, the reflective film can be taken directly from one of the insertion tubes 7 to complete the replacement process. There is no need for manual long-distance walking to carry the reflective film. It should be noted that after all the reflective films have been automatically transferred to the insertion tubes 7, the controller controls multiple sets of miniature electric push rods 10 to retract simultaneously to release the clamping and fixing of the paper tube. During the clamping process, the multiple sets of miniature electric push rods 10 move independently without interfering with each other.

[0057] As the production of semi-finished license plates continues, the reflective film on the insertion tube 7 will be removed one by one. When the vision camera detects that there is only one reflective film left on the turntable 3, it will immediately send a signal to the controller. The controller will then control the track-type electric flatbed trolley 12 to move back to the reflective film storage area to start the next round of automatic conveying and material transfer of reflective film in advance.

[0058] Compared with existing technologies, this device can automatically complete the batch transfer and conveying process of reflective film. When it is conveyed to one side of the turntable 3, it automatically transfers it to several insertion tubes 7 in sequence for subsequent replacement and retrieval. Manual transfer and retrieval of reflective film no longer requires manual handling. The automated conveying effect of reflective film is excellent and significantly reduces the labor intensity of manual conveying and transfer.

[0059] In other embodiments, such as Figure 1 As shown, the track-type electric flatcar 12 has a limit plate at the initial end of the track, and rubber blocks are installed on the limit plate.

[0060] In a further optimization of the above embodiment, a distance sensor is provided on the limiting plate, which is not shown in the figure. In this embodiment, the movement position of the track-type electric flatbed 12 can be limited by the limiting plate and the rubber block. The distance sensor can also prevent hard contact between the two, thereby accurately limiting the movement direction of the track-type electric flatbed 12 in the area near the turntable 3.

[0061] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
