[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0024] It should be understood that the "one embodiment" or "an embodiment" mentioned throughout the specification means that the specific features, structures or characteristics related to the embodiment are included in at least one embodiment of the present application. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner.

[0025] In the vehicle assembly process, glue is widely used for connection, sealing, fixing and other purposes. For example, structural glue that can withstand relatively large stress is used to replace traditional welding or bolt connection to provide strong adhesion for parts with high stress, and is often used for connection of vehicle body frame. Common structural glues include epoxy resin glue and polyurethane glue. In addition, there are sealing glue for waterproof, dustproof and leakproof, glass glue for bonding windshield, anticorrosive glue for preventing corrosion and oxidation of metal parts, high-temperature glue for high-temperature parts, heat-conducting glue for connecting and fixing electronic components, and conductive glue. According to the functional characteristics of different glues, suitable glue is selected for coating in many links of vehicle assembly, and the amount of coating work is very large. At present, robots 200 have been widely used in production to replace manual coating.

[0026] The robot 200 coating glue is controlled by program, which can accurately control the feeding, coating speed, glue path and thickness, improve the coating precision, and can work continuously and efficiently. In some high-temperature, high-pressure and toxic environments, workers can be prevented from being exposed to harmful environments. This greatly improves product quality and production efficiency, and can cooperate with other automatic equipment to realize the automation of the overall production line.

[0027] But no matter which glue is used, the glue has a certain flow and adhesion before complete curing, so it will inevitably adhere to the glue gun 210, affecting the normal glue application of the glue gun 210, and also easily dripping onto the vehicle body and other equipment, requiring additional cleaning work by humans. In manual glue application, workers can clean the glue gun 210 at any time, but in automated operation, the robot 200 always works continuously according to the set program, and must be stopped for cleaning, affecting the operation of the entire production line.

[0028] Based on the above problems, the utility model provides a cleaning device 100, which comprises: a support 1, a glue removing part 2 and a driving part 4, the glue removing part 2 and the driving part 4 are arranged on the support, the glue removing part 2 is rotatably connected with the support 1, and the driving part 4 is connected with the glue removing part 2, and the driving part 4 drives the glue removing part 2 to rotate relative to the support 1.

[0029] As shown in Figure 1 The support 1 is used to fix the cleaning device 100 at a specified position, and the specific shape, structure and connection mode of the support 1 do not affect the main function of the embodiment, so the support 1 is not limited here. In specific application, the cleaning device 100 can be installed on the robot 200 and connected to the control system of the robot 200, and after the robot 200 runs for a period of time, the cleaning program is entered, the robot 200 controls the glue gun 210 to move to the cleaning device 100 for cleaning work, or the cleaning device 100 can be moved to the glue gun 210, and the cleaning device 100 is started to remove glue, and after the glue removal is completed, it returns to the original position to continue the glue application work.

[0030] The support 1 is provided with the glue removing part 2 and the driving part 4. The surface of the glue removing part 2 is rough, and the residual glue is cleaned by friction generated by relative movement with the nozzle. On the one hand, the semi-cured glue with flow on the nozzle can be transferred to the surface of the glue removing part 2 during movement, and on the other hand, the residual glue that has been cured on the nozzle can be abraded and fallen off. The driving part 4 is connected to the power supply to rotate the glue removing part 2 connected with the driving part 4 relative to the nozzle of the glue gun 210. The power switch of the driving part 4 can be connected to the control system of the robot 200 and automatically turned on and off according to the program.

[0031] In specific application, the glue removing part 2 removes glue by wiping and abrasion, and the residual glue is only transferred from the nozzle to the glue removing part 2, so the glue on the surface of the glue removing part 2 is generally cleaned or the glue removing part 2 is replaced in time.

[0032] In this embodiment, the relative movement between the glue removing member 2 and the gun nozzle is mainly realized by the rotation of the glue removing member 2. After the glue applying robot 200 completes the glue applying operation, there is a waiting time of 30 seconds before the next glue applying operation, which can be used to automatically perform the glue removing operation by the robot 200. When performing the glue removing operation, the glue gun 210 is controlled to abut against the surface of the glue removing member 2, and the rotating glue removing member 2 wipes the excess glue around the gun nozzle, and the whole process is completed within 15 seconds. The rotating speed of the glue removing member 2 is between 50 rpm and 200 rpm, which can achieve a good cleaning effect and does not cause the glue to splash or damage the glue gun 210 due to too high rotating speed. The glue gun 210 needs to be cleaned once every 1.5 hours to ensure that the accumulated glue on the gun nozzle does not affect the glue applying quality. The above steps can be automatically performed by pre-setting programs in the robot 200, which does not interfere with the normal production process and improves the automation level while ensuring the glue applying quality.

[0033] In addition, in some optional embodiments, the cleaning device 100 further comprises a rotating member 3, the glue removing member 2 is detachably connected to the rotating member 3, the rotating member 3 is rotatably connected to the support 1, the driving member 4 is connected to the rotating member 3, and the driving member 4 drives the rotating member 3 to rotate relative to the support 1, and the rotating member 3 drives the glue removing member 2 to rotate relative to the support 1.

[0034] The rotating member 3 is similar to a rotating shaft and serves as a carrier for mounting and driving the glue removing member 2 to rotate. The glue removing member 2 itself can not be provided with a rotating shaft, which facilitates direct use of different types of finished products and does not need to be specially designed and produced. The rotating member 3 is used to connect the glue removing member 2 and the driving member 4. The driving member 4 is connected to the rotating member 3 and provides power to make the rotating member 3 connected to the driving member 4 rotate relative to the support 1, and drive the glue removing member 2 connected to the rotating member 3 to rotate relative to the gun nozzle of the glue gun 210.

[0035] Further, the glue removing member 2 and the rotating member 3 can be detachable, which facilitates timely replacement of the glue removing member 2 that is not suitable for continuous use.

[0036] In addition, in some optional embodiments, as shown in Figure 2 The driving member 4 comprises a fixed portion 41 and a rotating portion 42. The fixed portion 41 is fixedly connected to the support 1, and the rotating portion 42 is rotatably connected to the fixed portion 41. The rotating member 3 is fixedly connected to the rotating portion 42, and the rotating portion 42 can rotate relative to the support 1, and the rotating portion 42 drives the rotating member 3 to rotate relative to the support 1.

[0037] In this embodiment, the glue removing member 2 and the rotating member 3 are connected to the driving member 4 and indirectly connected to the support 1 through the driving member 4. The driving member 4 comprises a fixed portion 41 fixedly connected to the support 1 and a rotating portion 42 rotatable relative to the fixed portion 41.

[0038] The rotating member 3 can rotate coaxially with the rotating part 42, that is, the rotating member 3 is arranged at the center of the rotating part 42, so that the rotating member 3 does not displace itself, but only rotates around the center of the rotating member 3. The rotating member 3 can also be arranged at other positions of the rotating part 42, so that the rotating member 3 moves in a circular motion around a point other than the rotating member 3. Depending on the specific movement form of the rotating part 42, the above rotation does not necessarily complete a complete circular motion, but can also be a cyclic reciprocating rotation between specific positions. The movement form of the rotating member 3 and the glue removing member 2 connected to the rotating member 3 is not specifically limited in the embodiment.

[0039] In addition, in some optional embodiments, the rotating part 42 has a rotation axis, and the center of the rotating member 3 is arranged on the rotation axis, and the rotating part 42 drives the rotating member 3 to rotate around the rotation axis.

[0040] In the embodiment, the rotating part 42 of the driving member 4 and the rotating member 3 are coaxially arranged, and the rotating member 3 serves as the rotating shaft of the glue removing member 2, and drives the glue removing member 2 to rotate around the shaft. Compared with the case where the glue removing member 2 revolves around a point other than the glue removing member 2, the glue removing member 2 does not displace itself when rotating, and keeps contact with the gun nozzle of the glue gun 210 during the entire rotation process.

[0041] In addition, in some optional embodiments, the rotating member 3 is cylindrical, and the glue removing member 2 is wound on the cylindrical surface of the cylindrical rotating member 3.

[0042] In specific applications, a pin can be used as the rotating member 3, which is inserted into the rotating part 42 of the driving member 4 and fixedly connected to the rotation axis of the rotating part 42, which is usually the driving shaft of the rotating cylinder. The pin and the rotating cylinder are both finished products that are easy to obtain. This combination is easy to implement, easy to install, and relatively low in cost.

[0043] The glue removing member 2 is arranged around the cylindrical rotating member 3 and rotates around the rotating member 3, and the outer circumferential surface of the glue removing member 2 is the contact surface with the glue gun 210. The outer circumferential surface rotates to achieve the effect of cleaning glue. The glue removing member 2 and the rotating member 3 can be connected by adhesion.

[0044] In addition, in some optional embodiments, the glue removing member 2 is a non-woven fabric glue removing member 2.

[0045] In the embodiment, the glue removing member 2 can be made of non-woven fabric. The non-woven fabric has a wiping effect and can wipe off the residual glue on the surface of the gun nozzle. In addition, the non-woven fabric has a certain water absorption. When cleaning glue with flowability, the non-woven fabric can better absorb the glue, prevent the glue from splashing, and bring additional cleaning work.

[0046] The non-woven fabric product provided in the market at present is a roll-shaped finished non-woven fabric roll with a tearable line, and the non-woven fabric roll is sleeved on the rotating member 3 and rotates coaxially with the rotating member 3, so as to take away the adhesive attached around the glue gun 210. After a certain number of cycles, the waste non-woven fabric is torn off, which is convenient to replace, and only the fixing between the non-woven fabric roll and the rotating member 3 needs to be done to prevent the non-woven fabric roll from being scattered when rotating. This scheme has a problem that each time the non-woven fabric is torn off, the thickness of the non-woven fabric roll will be reduced, and the rotating radius will also be reduced, so that the gun nozzle needs to be repositioned before each time of glue removal to abut against the outer surface of the non-woven fabric roll.

[0047] In view of the above situation, a sheet-shaped non-woven fabric can also be used alone, and a piece of non-woven fabric is bonded to the rotating member 3, torn off after glue removal, and replaced with a new non-woven fabric. Although the non-woven fabric needs to be bonded again after each time of glue removal, the thickness of the glue removal member 2 does not change with the accumulation of the number of glue removal times, and the rotating radius is basically stable, so the robot 200 only needs to control the glue gun 210 and the cleaning device 100 to move to the same position, without the need for accurate positioning each time of glue removal.

[0048] In addition, in some optional embodiments, the glue removal member 2 is a brush glue removal member 2.

[0049] In addition to the non-woven fabric introduced in the above embodiments, a brush can also be used as the glue removal member 2. The brush has a better wiping effect than the non-woven fabric, can clean the surface of the glue gun 210 more thoroughly, and is convenient to clean. The brush can be soaked in a cleaning solution to conveniently remove residual glue, and can be recycled multiple times without replacement in a short period of time. However, there is a problem with using a brush to remove glue, that is, the surface of the brush is densely covered with small bristles, which are more likely to throw off the adhesive attached to the bristles during rotation. To solve this problem, a protective cover can be installed on the support 1 to form a relatively closed space, and an opening is reserved on the protective cover for the glue gun 210 to enter. The robot 200 controls the glue gun 210 to extend into the protective cover to remove glue, and the adhesive thrown off by the glue removal member 2 during rotation is collected in the protective cover to solve the problem of splashing of the adhesive.

[0050] In an implementation manner, the brush glue removal member 2 can be a long-handle nylon brush similar to a test tube brush. The brush handle is coaxially connected with the rotating member 3 as the rotating shaft of the glue removal member 2, and the brush rotates around the shaft to continuously remove the residual glue on the surface of the glue gun 210.

[0051] In other implementation manners, the brush glue removal member 2 can also be a flexible sheet-shaped structure. One side of the brush sheet is smooth, and the other side is densely covered with small bristles. The brush sheet is wound into a cylindrical shape, the smooth surface is bonded to the surface of the rotating member 3, and the bristle surface faces outward and rotates with the rotation of the rotating member 3 to wipe off the residual glue around the glue nozzle.

[0052] The non-woven fabric glue removing member 2 and the brush glue removing member 2 are only examples, and in actual application, a paper, a sponge, a wire and other fiber products can also be used as the glue removing member 2.

[0053] In addition, in some optional embodiments, the driving member 4 is a rotary air cylinder, and a gas pipe joint 43 is arranged on the rotary air cylinder, and gas is introduced into the gas pipe joint 43 to rotate the rotating part 42 relative to the support 1.

[0054] In the embodiment, the driving member 4 is mainly a vane rotary air cylinder, compressed air is introduced into the rotary air cylinder through the gas pipe joint 43, the piston is pushed to move along a specific path in the rotary air cylinder, the movement of the piston is converted into rotary motion through the connection with the driving shaft, and the rotary motion is transmitted to the rotating part 3 connected with the rotary air cylinder through the driving shaft, so that the rotating part 3 rotates synchronously with the piston.

[0055] In addition, in some optional embodiments, the support 1 is provided with a mounting hole 11 for fixing the cleaning device 100.

[0056] Specifically, the fixing of the cleaning device 100 can be achieved by using fasteners such as bolts and pins.

[0057] The utility model provides a kind of cleaning device 100, including support 1, glue removing member 2, rotating part 3 and driving member 4, the rotating part 3 and the driving member 4 are arranged in the support 1, the rotating part 3 is rotatably connected with the support 1, the glue removing member 2 is fixedly connected to the rotating part 3, the driving member 4 is connected with the rotating part 3, the driving member 4 drives the rotating part 3 relative to the support 1 rotation, the rotating part 3 drives the glue removing member 2 relative to the support 1 rotation. The rotation of glue removing member 2 is used to wipe off the semi-solid glue remaining on the gun nozzle of glue gun 210, to prevent residual glue from affecting the glue application effect of glue gun 210. By setting program, cooperate with glue application robot 200, automatic glue wiping can be realized, equipment is more automated, improve production efficiency, and the entire cleaning device 100 is simple to assemble, easy to maintain.

[0058] Another aspect of the utility model is to propose a kind of automatic gluing system. Figure 3 As shown in the figure, the utility model embodiment further provides a kind of automatic gluing system, including robot 200 with glue gun 210 and any one cleaning device 100 in the first aspect, glue gun 210 includes gun nozzle, when residual glue is cleaned, control gun nozzle and the surface of glue removing member 2 abut.

[0059] In combination with a specific use scenario, the cleaning device 100 can be fixed at a certain position of a production line, or can be installed on the robot 200 and driven by the robot 200 to a designated position. A program is pre-set in the robot 200 to perform glue removal during the interval between two glue coating operations, and when glue removal needs to be performed, the robot 200 automatically controls the nozzle of the glue gun 210 to abut against the glue removal member 2 of the cleaning device 100 to perform glue removal.

[0060] Generally, the position of the cleaning device 100 is fixed, and the glue removal member 2 only contacts one side of the glue gun 210, and the glue removal effect on the other side is poor. In order to fully remove the residual glue on the glue gun 210, the robot 200 can control the glue gun 210 to move every certain period of time, so that each position of the nozzle of the glue gun 210 contacts the glue removal member 2. Alternatively, two cleaning devices 100 can be provided, the glue removal members 2 of the two cleaning devices 100 are oppositely arranged, and the nozzle of the glue gun 210 is clamped between the two glue removal members 2 to improve the glue removal effect.

[0061] For the above-mentioned automatic glue coating system embodiment, since it is basically similar to the cleaning device 100 embodiment, the description is relatively simple, and the relevant parts are described in the part of the cleaning device 100 embodiment.

[0062] It should be noted that each embodiment in the present specification is described in a progressive manner, and each embodiment focuses on the difference from other embodiments, and the same parts between each embodiment can be referred to each other.

[0063] Although the optional embodiments of the present application have been described, those skilled in the art can make further changes and modifications to these embodiments once they know the basic creative concept. Therefore, the appended claims are intended to include the optional embodiments and all changes and modifications falling within the scope of the present application.

[0064] Finally, it should be noted that in this paper, relationship terms such as first and second are only used to distinguish one entity from another, and do not necessarily require or imply any such actual relationship or order between the entities. Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the article or terminal device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such article or terminal device. Without more limitations, the element defined by the statement "including a" does not exclude the presence of another identical element in the article or terminal device including the element.

[0065] The above technical solutions provided by the utility model are described in detail, and the principles and implementation manners of the utility model are described by applying specific examples, and for the general technical personnel in the field, the principles and implementation manners of the utility model will have changes in the specific implementation manners and application ranges, and in conclusion, the content of the specification should not be understood as the limitation of the utility model.
