Description

Technical Field

[0001] The utility model relates to the technical field of glue application, in particular to a sheath structure for a glue application pipe and a glue application system. Background Art

[0002] With the continuous improvement of product quality requirements, the requirements for glue application speed and quality in the glue application technology field are becoming increasingly strict. Therefore, it has become increasingly common to configure a vision device capable of real-time monitoring of glue application quality in a glue application system. To ensure the accuracy of the collected data and make reasonable use of the space resources of the glue application system, the vision device is usually installed at an intermediate position between the end of the glue application pipe and the glue gun. This can not only effectively utilize the space where the slender glue application pipe is located, but also ensure the quality of the images collected by the vision device. In addition, the clearance holes provided on the vision device can facilitate the passing of the slender glue application pipe without affecting its normal use.

[0003] However, in order to protect the slender glue application pipe, a sheath is usually installed on its outer part. Although the sheath can effectively protect the glue application pipe, it will cause an increase in the overall cross-sectional area formed by the sheath and the glue application pipe. On the premise that the size of the clearance hole of the vision device remains unchanged, even if the size of the clearance hole is larger than the outer diameter of the sheath, it is still difficult to directly remove the whole formed by the sheath and the glue application pipe. Even if an attempt is made to tilt and remove the overall structure (as shown in the attached Figure 2 figure), due to the limited tilting angle and the large overall end size, it is impossible to complete the disassembly work in the narrow space between the vision device and the glue gun. This makes it necessary to first remove the vision device when the glue application pipe needs to be disassembled, increasing the complexity of the disassembly of the glue application pipe. Summary of the Utility Model

[0004] The utility model aims to provide a sheath structure for a glue application pipe and a glue application system to solve the problem that it is difficult to directly remove the whole formed by the sheath and the glue application pipe due to the installation of a vision device at the middle position between the glue gun and the end of the glue application pipe at present.

[0005] To achieve the above object, the utility model adopts the following technical scheme:

[0006] A sheath structure for a glue application pipe includes a sheath body, the sheath body includes an upper sheath segment and a lower sheath segment, the upper sheath segment and the lower sheath segment are detachably connected, and the maximum cross-sectional dimension of the lower sheath segment is smaller than the cross-sectional dimension of the clearance hole on the vision device.

[0007] The principle and advantages of this solution are as follows: The core of this solution lies in dividing the sheath structure into a detachable upper sheath and a lower sheath. When it is necessary to disassemble the glue applicator tube, since the connection position between the lower sheath and the upper sheath is located between the vision device and the glue gun, at this time, only the connection between the lower sheath and the upper sheath needs to be released, and then the lower sheath can be taken out from the glue applicator tube along the clearance hole. After taking it out, the glue applicator tube opposite to the clearance hole position obtains a larger free space in the clearance hole because the lower sheath is removed. Then, only the sheath structure and the glue applicator tube need to be removed from the glue gun. After that, the whole formed by the upper sheath and the glue applicator tube is tilted. Due to the larger free space, the tilting angle can also be larger, which facilitates the direct disassembly of the glue applicator tube without disassembling the vision device, greatly simplifying the disassembly process of the glue applicator tube. Similarly, when installing the glue applicator tube, the whole formed by the upper sheath and the glue applicator tube can be inserted into the clearance hole first, and then the lower sheath can be inserted into the clearance hole to complete the installation.

[0008] Preferably, as an improvement, both ends of the upper sheath and the lower sheath close to each other are provided with protrusions facing the outer periphery, and further include a clamp or a hoop for fastening between the upper and lower protrusions, ensuring the stability and reliability of the connection between the upper sheath and the lower sheath, and facilitating disassembly at the same time.

[0009] Preferably, as an improvement, the upper sheath is provided with a female joint, and the lower sheath is provided with a male joint. The female joint and the male joint are connected in any one of the threaded connection method / flange quick connection method / wrench handle method. This solution realizes the quick connection and disassembly between the upper sheath and the lower sheath, improving the efficiency of the maintenance and replacement of the glue applicator tube.

[0010] Preferably, as an improvement, the upper sheath and the lower sheath are in concave-convex fit at the docking position to enhance the overall stability of the sheath structure and help ensure the coaxiality of the upper sheath and the lower sheath.

[0011] Preferably, as an improvement, the lower sheath is inserted into the upper sheath to ensure stable connection while enabling the size of the lower sheath to be made smaller.

[0012] Preferably, as an improvement, the axial length dimension of the upper sheath is smaller than the axial length dimension of the lower sheath.

[0013] Preferably, as an improvement, the upper sheath is used for detachable connection with the glue gun.

[0014] The present utility model also provides a glue coating system, which includes a glue gun and a glue coating tube installed at the discharge port of the glue gun. It further includes the above-mentioned sheath structure for the glue coating tube sleeved outside the glue coating tube. By integrating the sheath structure for the glue coating tube in the glue coating system, the protection and maintenance convenience of the glue coating tube are ensured, which helps to ensure the reliability and consistency of the quality monitoring of the glue coating system.

[0015] Preferably, as an improvement, the glue coating tube is a mixing tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following is further detailed through specific embodiments:

[0024] The reference numerals in the accompanying drawings of the specification include: upper section of the sheath 1, lower section of the sheath 2, annular protrusion 12, hoop 3, groove 31, glue gun 10, glue coating tube 20, vision device 30, clearance hole 40.

[0025] The embodiment is basically as shown in the attached Figures 3 to 6 figure.

[0026] A sheath structure for a glue coating tube includes a sheath body. The sheath body includes an upper section of the sheath 1 and a lower section of the sheath 2. The upper section of the sheath 1 and the lower section of the sheath 2 are detachably connected. The maximum cross-sectional dimension of the lower section of the sheath 2 is smaller than the cross-sectional dimension of the clearance hole 40 on the vision device 30.

[0027] At one end where the upper sheath section 1 and the lower sheath section 2 are close to each other, there are annular protrusions 12 facing the outer periphery. There is also a clamp or hoop 3 for fastening between the upper and lower protrusions. In this embodiment, the hoop 3 is adopted, including a left-right rotation connection method. A groove 31 for fastening the upper and lower annular protrusions 12 is provided on the hoop 3.

[0028] The upper sheath section 1 and the lower sheath section 2 are in concave-convex fit at the butt end face. The lower sheath section 2 is inserted into the upper sheath section 1. Specifically, the lower sheath section 2 is processed with an annular boss facing the upper sheath section 1, and the upper sheath section 1 is processed with a sunk groove for accommodating the annular boss. The sunk groove and the annular boss are coaxial, which helps to ensure the coaxiality of the upper sheath section 1 and the lower sheath section 2.

[0029] The axial length dimension of the upper sheath section 1 is smaller than the axial length dimension of the lower sheath section 2.

[0030] The upper sheath section 1 is provided with a flange with mounting holes at the top, and the flange is used to connect with the glue gun 10 through screws.

[0031] When the sheath structure of this embodiment is installed on the glue gun 10 together with the glue application tube 20, and when the glue application tube 20 needs to be disassembled, since the connection position between the lower sheath section 2 and the upper sheath section 1 is located between the vision device 30 and the glue gun 10, at this time, only the connection between the lower sheath section 2 and the upper sheath section 1 needs to be released, and then the lower sheath section 2 can be taken out from the glue application tube 20 along the clearance hole 40. After taking it out, the glue application tube 20 at the position facing the clearance hole 40 obtains a larger free space in the clearance hole 40 because the lower sheath section 2 is removed. Then, only the sheath structure and the glue application tube 20 need to be removed from the glue gun 10. After that, the whole formed by the upper sheath section 1 and the glue application tube 20 is tilted. Due to the larger free space, the tilt angle can also be larger, which facilitates directly disassembling the glue application tube 20 without disassembling the vision device 30, greatly simplifying the disassembly process of the glue application tube 20. Similarly, when installing the glue application tube 20, the whole formed by the upper sheath section 1 and the glue application tube 20 can be inserted into the clearance hole 40 first, and then the lower sheath section 2 can be inserted into the clearance hole 40 to complete the installation.

[0032] In addition, if the whole formed by the glue application tube 20 and the upper sheath section 1 affects the tilted removal after the lower sheath section 2 is disassembled, the upper sheath section 1 can be slid down along the glue application tube 20 to reduce the cross-sectional size at the top of the glue application tube 20, making it more convenient to take out the glue application tube 20.

[0033] Embodiment Two

[0034] The difference between the second embodiment and the first embodiment is that the detachable connection between the upper section 1 and the lower section 2 of the sheath in the second embodiment is directly designed in the form of a male and female joint. The female joint and the male joint are connected by any one of a threaded connection method / a flange quick connection method / a wrench handle method. The male joint is arranged on the lower section 2 of the sheath, and the female joint is arranged on the upper section 1 of the sheath, so that the cross-section of the male joint is smaller, which is convenient for pulling out the lower section 2 of the sheath from the clearance hole 40 on the vision device 30.

[0035] The structure of the male and female joints in this embodiment is common in the quick disassembly of current metal pipes, and this embodiment will not be described separately in the view.

[0036] Embodiment Three

[0037] Combined with Figure 7 , a gluing system includes a glue gun 10 and a glue application tube 20 installed at the discharge port of the glue gun 10. It further includes a sheath structure for the glue application tube as described in the first embodiment or the second embodiment and sleeved outside the glue application tube 20. The glue application tube 20 is a mixing tube for mixing glue A and glue B.

[0038] By integrating the above-mentioned sheath structure for the glue application tube in the gluing system in this embodiment, the protection and maintenance convenience of the glue application tube 20 are ensured. At the same time, on the basis that the vision device 30 does not need to be disassembled when disassembling and assembling the glue application tube 20, it also helps to ensure the reliability and consistency of the quality monitoring of the gluing system.

[0039] The above are only the embodiments of the present utility model. Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicality of the patent.
