Description

Technical Field

[0001] The present invention relates to the technical field of special bundling for electronic connecting wires, and more specifically, it relates to an automatic bundling machine for the production of electronic connecting wires. Background Art

[0002] During the use of an existing automatic wire bundling machine, although the automated usage procedures are complete, there are still some problems in the bundling of electronic connecting wires;

[0003] It should be noted that the automatic wire bundling machine has extremely poor adaptability when bundling wire harnesses of different specifications and shapes, and it is difficult to bundle the wires appropriately. Due to the influence of the nature of the wires themselves, the thickness of the electronic connecting wires is different. If the bundling strength is too low, the bundling may become loose and unable to be effectively fixed. When the bundling machine processes thin signal wires, the bundling strength may be set too high, resulting in the wire harness being pressed too tightly, and even the insulation layer may be damaged. Moreover, the overly tight wire harness may short-circuit in a high-temperature environment. Therefore, different from conventional automatic bundling machines, this problem has not been effectively solved in the bundling machine applied to electronic connecting wires;

[0004] Therefore, we urgently need to design an automatic bundling machine for the production of electronic connecting wires that can give a bundling force matching the size of electronic connecting wires of different sizes. Summary of the 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.

[0025] Embodiment 1:

[0026] The following is further described in detail in conjunction with the attached Figures 1-7 for the present invention.

[0027] Please refer to Figures 1-7 , the present invention provides a technical solution: an automatic bundling machine for the production of electronic connecting wires. As Figures 1-7 shown, it includes an equipment support base 1. A equipment support frame 3 is arranged on the top of the equipment support base 1. A connecting bearing seat 4 is arranged on the top of the equipment support frame 3. A conveyor track 7 is arranged on the top of the connecting bearing seat 4. A camera observation plate 5 is arranged on the top of the conveyor track 7. A distance measuring camera 6 is installed inside the camera observation plate 5. The distance measuring camera 6 is used to monitor the size of the materials on the top of the conveyor track 7. A material supporting plate surface 2 is arranged inside the conveyor track 7. The material supporting plate surface 2 is fixedly connected to the camera observation plate 5. The material supporting plate surface 2 is used as the support for the conveyor track 7 and is fixedly connected to the equipment support frame 3. A pulling and bundling block 8 is arranged on the outside of the conveyor track 7. A bundling and gathering roller 9 is installed on the surface of the pulling and bundling block 8. It should be supplemented here that the setting of the above structure refers to a part of the existing packaging machine.

[0028] Among them, it is elaborated in detail Figure 1The specific linkage working principle in it, but considering the creative part of this case, we can only select a certain part of it for creation. The redundant structure in its entire process is not what we need, so it will not be presented here. It can be seen that in the above structure, our main innovative structures are the camera observation board 5, the conveyor track 7, the distance measuring camera 6, and the bundling and shrinking roller 9. The following briefly describes this working principle. Through the setting of the conveyor track 7, it can rely on the material supporting plate surface 2 as the overall operation support and carry and transport materials on the outside of the material supporting plate surface 2. When the material is placed on the surface of the material supporting plate surface 2, it is first supported by the conveyor track 7. At this time, during the transportation of the conveyor track 7, the materials to be transported will be gradually gathered, and then be bundled by the bundling and shrinking roller 9 within the working range of the pulling and bundling block 8, so as to package the materials. It should be noted that during the process of the materials entering the surface of the conveyor track 7 and being gathered, the parameter adjustment of the bundling and shrinking roller 9 is restricted by the observation data of the distance measuring camera 6. The distance measuring camera 6 can directly measure the material parameters, so as to adjust the reset distance of the bundling and shrinking roller 9, and then achieve the purpose of summarizing and gathering the materials;

[0029] The gathering cylinder 10, the gathering cylinder 10 penetrates through the surface of the conveyor track 7. There is a clamping inner sleeve 14 above the gathering cylinder 10. There is a magnetic adsorption block 15 outside the clamping inner sleeve 14. The magnetic adsorption block 15 is clamped inside the clamping inner sleeve 14. The magnetic adsorption block 15 is also arranged inside the gathering cylinder 10. There are buckles outside the clamping inner sleeve 14. There is a bayonet matching the buckle on one side of the gathering cylinder 10 close to the clamping inner sleeve 14. There is a gathering cylinder 16 inside the clamping inner sleeve 14. There is a rotating connecting shaft 17 in the middle of the gathering cylinder 16. The input end of the rotating connecting shaft 17 is provided with a starting motor. There is a preset moving track 18 outside the rotating connecting shaft 17. The conveyor track 7 penetrates between the gathering cylinders 16;

[0030] In this embodiment: During the use process, the electronic connection wires on the surface of the conveyor track 7 are preferentially bundled, and then bundling can be carried out. Next, we will describe the overall working principle of the clamping inner sleeve 14. During the use of the device, it can be seen that the conveyor track 7 can access the inside of the clamping inner sleeve 14 through the gap between the converging clamping cylinder 10 and the clamping inner sleeve 14, and then unfold on the top of the two converging cylinders 16, or directly place the conveyor track 7 into the inside of the converging cylinder 16 for penetration. When the electronic connection wires pass through the converging cylinder 16, the induction device set inside the clamping inner sleeve 14 will be activated at this time, and then drive the rotating connecting shaft 17 to start at the same time. Under the limitation of the preset moving track 18, the conveyor track 7 is squeezed and bundled, so as to effectively ensure that the electronic connection wires can be pre-bundled before bundling, and avoid the problem that the bundling and shrinking roller 9 is unevenly stressed during bundling due to the gaps between the electronic connection wires. Then it should be noted that according to different installation situations, the preset moving track 18 can be disassembled and adjusted to replace different running tracks. The main installation method shown in the figure is that the preset moving track 18 at the top is vertically installed at the bottom of the inner cavity of the clamping inner sleeve 14. Among them, the converging cylinder 16 at the top mainly plays a supporting role, which is used to gather the two converging cylinders 16 below when they are combined. At the same time, the magnetic adsorption block 15 can be used for magnetic connection adsorption and can also be disassembled, and is clamped by the clamping parts set above to ensure the use effect of the device. Therefore, through the setting of this structure, it is not necessary for the user to pre-gather the electronic connection wires. During this process, only the head and tail need to be integrated to carry out bundling. However, according to operation experience, the integration of the head and tail can also be intervened later, which does not affect the implementation of this step.

[0031] As Figures 1-7 shown, three distance measuring cameras 6 are set as a group inside the camera observation board 5. The distance measuring cameras 6 are set in multiple groups. The three distance measuring cameras 6 in a group are centered on the distance measuring camera 6 set in the center, and the left and right setting angles are ±5°, so as to monitor the surface material data of the conveyor track 7. The surface of the conveyor track 7 is drawn with scales showing cross axes, and the camera observation board 5 is set as a curved surface;

[0032] In this embodiment, it should be noted that while monitoring data through the camera observation board 5 and the ranging camera 6, special attention should be paid to the fact that when the conveyor track 7 moves the materials on its surface, the electronic connection wires to be bundled often have different angles. If the data is measured individually, it is very easy to have data deviation due to different observation angles. Therefore, we distribute the ranging cameras 6 along the arc angle of the camera observation board 5. During the distribution of the ranging cameras 6, in order to reduce the observation deviation, we also set the observation angles of the ranging cameras 6 and process the observation data of each ranging camera 6 independently. Since the conveyor track 7 itself has scales, when the electronic connection wires are placed on the surface of the conveyor track 7, the conveyor track 7 can serve as an observation reference for the electronic connection wires. Thus, the ranging camera 6 starts to observe, and the captured images are imported into the image processing software for image preprocessing. Specifically, the observed electronic connection wire images are grayscaled, binarized, etc., so as to more easily identify the contours of the electronic connection wires. Then, an edge detection algorithm is used to identify the edges of the objects. From the extracted contours, the diameter of the electronic connection wires is calculated. Then, we record the pixel diameter of the electronic connection wires on the surface of the conveyor track 7 in the image, and then perform pixel processing through the scales on the surface of the conveyor track 7, so as to convert the pixel diameter of the captured electronic connection wires into the actual size. Specifically applied to the actual situation, it is to multiply the pixel diameter of the object by the conversion ratio to obtain the actual diameter. In our setting, there are a total of three groups of ranging cameras 6, corresponding to nine ranging cameras 6. Therefore, we will obtain nine groups of measurement results, and take the average of the nine groups of measurement results to obtain the diameter of the electronic connection wires transported by the conveyor track 7 observed by the ranging cameras 6. Then, this data is transmitted to the bundling and gathering roller 9 to adjust the bundling force of the bundling and gathering roller 9.

[0033] As Figures 1-7 shown, the conveyor track 7 is set with multiple groups spliced together. There are restraint clips 11 arranged on both sides of the conveyor track 7. The multiple restraint clips 11 are detachably connected through the middle. The width of the conveyor track 7 is smaller than the set width of the restraint clips 11. The gathering cylinder 10 is used to gather the materials on the surface of the conveyor track 7. A counter-bearing rod 13 movably penetrates through the lower part of the gathering cylinder 10. A positioning wedge 12 is arranged at one end of the counter-bearing rod 13 away from the gathering cylinder 10. The positioning wedge 12 is opened on the inner side of the material supporting plate surface 2. The counter-bearing rod 13 is used to support the horizontal movement of the gathering cylinder 10;

[0034] In this embodiment, it is supplemented here that it can be seen that the above-mentioned mechanism is mostly used for limiting the setting of the conveying material of the conveyor belt 7, and is proposed as a pre-binding process for bundling the electronic connecting wires. In this process, in order to ensure that the entire device can be used automatically, we give priority to splitting the conveyor belt 7 from the conventional conveyor belt 7, and install the conveyor belt 7 on the top of the material supporting plate 2 with a splicing design. The conveyor belt 7 is given elastic winding in the process of carrying the material through the tightening spring 11, and the setting of the gathering clamp 10 is used to enable it to wind the material in advance. In order to facilitate the subsequent bundling, the use of the device is guaranteed, and one thing that needs to be guaranteed is that when the bundling clamp 11 is set, a torsion spring is provided inside it. Considering the problem of the bearing material, the torsion force of the torsion spring must be greater than the body weight of the conveyor belt 7 and the tension of the conveyor belt 7 itself, and it also needs to be greater than the weight of the electronic connection line itself in order to play a normal supporting effect. Taking this into account, when the gathering clamp 10 pre-bundles the electronic connection line on the surface of the conveyor belt 7, it needs to be bundled together with the conveyor belt 7 before it can enter the normal bundling link of the bundling and bundling roller 9. It should also be explained that Figure 4 The size of the gathering collet 10 is only used as an installation diagram and does not represent the final size of the gathering collet 10.

[0035] like Figures 1-7 As shown, the surface of the bundling and collecting roller 9 is provided with a bundling belt outlet 19, and the periphery of the bundling belt outlet 19 is provided with a movable rod to reduce the internal friction coefficient of the bundling and collecting roller 9 during use. The interior of the bundling and collecting roller 9 is provided with a bundling belt storage bin 20, and the interior of the bundling belt storage bin 20 is provided with a built-in adjustment spring rod 21. A pulling joint block 22 is provided at one end of the bundling and collecting roller 9, and a supporting positioning base plate 29 is provided at the bottom of the pulling joint block 22. Pulling card plates 23 are provided at both ends of the pulling joint block 22. The pulling joint block 22 is connected through the pulling card plate 23 and the supporting positioning base plate 29, and a pressure measuring plate is provided on the surface of the pulling card plate 23. The device 24 supports and positions the rear surface of the base plate 29 and is provided with an adjusting shaft 25. The adjusting shaft 25 is arranged at a position corresponding to the installation position of the pulling card 23. The interior of the adjusting shaft 25 is connected with a built-in rotating shaft 26. The surface of the built-in rotating shaft 26 is wrapped with a tightening pulling belt 27. The tightening pulling belt 27 is used to pull the pulling card 23. A rotating block 28 is provided at one end of the built-in rotating shaft 26. The rotating block 28 is clamped in the interior of the adjusting shaft 25 to rotate the built-in rotating shaft 26. The end of the tightening pulling belt 27 away from the built-in rotating shaft 26 is fixedly connected to the bottom of the pulling card 23 to pull and adjust the length of the pulling card 23.
