Technical Field

[0001] This utility model belongs to the field of rivet glue application technology, specifically relating to an automatic glue application machine. Background Technology

[0002] For some sheet metal equipment with sealing requirements, when parts are connected using blind rivets or grooved rivets, the rivets need to be pre-applied with adhesive to seal the gaps at the joint between the parts and the rivets. Current adhesive application methods generally use a manual rivet gun, where one hand pushes the gun to dispense adhesive while the other hand holds the rivet and manually rotates it to distribute the adhesive evenly around the outer circumference of the rivet shank.

[0003] This method of applying glue has the following disadvantages:

[0004] (1) It requires both hands to operate, which is difficult and inconvenient;

[0005] (2) The glue application efficiency is low and the quality is unstable. Excessive glue output will cause glue waste, and the overflowing glue is difficult to handle. Insufficient glue output will affect the sealing performance during rivet assembly. Utility Model Content

[0006] The purpose of this invention is to provide an automatic glue applicator to solve the problems of low glue application efficiency and high operational difficulty in rivet application.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0033] like Figure 1-4As shown, an automatic glue applicator includes a frame 1, a glue applicator 2, and a clamping assembly 3. The glue applicator 2 is vertically mounted on the frame 1 and includes a self-heating glue tank 2-1 that can move up and down on the front side of the frame 1. The self-heating glue tank 2-1 includes a glue container 2-2, a heating sleeve 2-3 that is fitted over the glue container 2-2, and an insulation sleeve 2-4 that is fitted over the heating sleeve 2-3. A glue pusher is provided on the top of the glue container 2-2, and a glue outlet 2-15 at the lower end of the glue container 2-2 extends from the lower end of the insulation sleeve 2-4. The clamping assembly 3 is located below the frame 1 and includes a pneumatic chuck 3-1 located below the self-heating glue container 2-1 and a motor 3-2 for driving the pneumatic chuck 3-1 to rotate.

[0034] The clamping assembly 3 is used to fix the rivet, that is, to clamp the rivet between the jaws of the pneumatic chuck 3-1. The glue outlet 2-15 at the lower end of the glue bucket 2-2 is located above the rivet to dispense glue. During the glue dispensing process, the motor 3-2 drives the pneumatic chuck 3-1 to rotate, so as to realize the rotation of the rivet, thereby performing a uniform glue application operation on the outer ring of the rivet.

[0035] The frame 1 includes a portal frame 1-1 and a base plate 1-2 at the bottom of the portal frame 1-1. The glue applicator 2 is mounted on the portal frame 1-1, and the clamping assembly 3 is mounted on the base plate 1-2 and located below the portal frame 1-1.

[0036] Motor 3-2 may be, but is not limited to, stepper motor 3-2.

[0037] Since rivets of different specifications (different outer diameters) have different heights, in order to adjust the height of the glue tube opening 2-15 according to the position of the rivet to ensure that the glue can be accurately applied to the rivet, the self-heating glue tank 2-1 is designed with an adjustable height. To achieve this purpose, the glue application assembly 2 also includes a lifting cylinder 2-5 installed on the frame 1, which drives the self-heating glue tank 2-1 to move up and down.

[0038] Specifically, the piston rod of the lifting cylinder 2-5 is set downwards, and the end of the piston rod is fixed to the top of the frame 1 by the connecting plate 2-6. The self-heating glue bucket 2-1 is fixed to the front side of the lifting cylinder 2-5 by the mounting plate 2-7.

[0039] The lifting cylinder 2-5 has a vertical plate 2-8 on its front side. The mounting plate 2-7 of the self-heating glue tank 2-1 is fixed on the vertical plate 2-8. When the piston rod of the lifting cylinder 2-5 extends, it can drive the self-heating glue tank 2-1 to rise. Conversely, when the piston rod of the lifting cylinder 2-5 retracts, it can drive the self-heating glue tank 2-1 to fall.

[0040] In order to heat the glue in the glue bucket 2-2 in real time and prevent it from becoming semi-solid due to low temperature, which would affect the glue application effect, several heating coils 2-9 are wrapped around the heating sleeve 2-3. The heating coils 2-9 are connected to an external power source.

[0041] In order to monitor the temperature of the glue in glue bucket 2-2 in real time, a temperature sensor (not shown in the figure) is installed on the outer wall of glue bucket 2-2.

[0042] In addition, the temperature sensor can be placed not only on the outer wall of the glue bucket 2-2, but also at the bottom of the glue pusher plate 2-12 to detect the temperature of the glue.

[0043] To facilitate the arrangement of wiring connected to the heating coil 2-9 and the temperature sensor, a wiring seat 2-10 is provided on one side of the mounting plate 2-7.

[0044] Preferably, the cable tray 2-10 is provided with a cable hole, through which the cable can be arranged to avoid the problem of messy cable.

[0045] In order to push the glue out of the glue outlet 2-15 of the glue bucket 2-2 and realize the glue application operation, the glue pushing component includes a glue pushing cylinder 2-11 set on the top of the glue bucket 2-2, and a glue pushing plate 2-12 connected to the lower end of the piston rod of the glue pushing cylinder 2-11 and located inside the glue bucket 2-2.

[0046] In order to position the glue-pushing cylinder 2-11 and the glue bucket 2-2, a clamping frame 2-13 is provided above the heat insulation sleeve 2-4, and a clamping screw 2-14 with its lower end abutting against the top of the glue-pushing part is installed on the clamping frame 2-13.

[0047] The clamping frame 2-13 is an inverted U-shaped frame, with both ends rotatably mounted on the outer wall of the insulation sleeve 2-4. The clamping screw 2-14 is threaded onto the clamping frame 2-13. When fixing the glue-pushing cylinder 2-11, the clamping frame 2-13 is placed vertically. At this time, the clamping screw 2-14 is rotated so that its bottom rests against the top of the glue-pushing cylinder 2-11, thus fixing the glue-pushing cylinder 2-11 and the glue bucket 2-2 and preventing them from shaking during the glue application process.

[0048] In order to fix the pneumatic chuck 3-1 and the motor 3-2, the clamping assembly 3 includes a mounting bracket set below the frame 1, and the pneumatic chuck 3-1 is fixed to one side of the mounting bracket.

[0049] The mounting bracket includes a fixing block 3-3 mounted on the base plate 1-2 and a vertical plate 3-4 set on one side of the fixing block 3-3. The mounting seat of the pneumatic chuck 3-1 is fixed on one side of the vertical plate 3-4, and the end of the pneumatic chuck 3-1 with the gripper facing forward is opposite to the glue outlet 2-15 of the glue bucket 2-2 above it. The motor 3-2 is set on the rear side of the mounting seat of the pneumatic chuck 3-1 to drive the pneumatic chuck 3-1 and the rivets clamped on the pneumatic chuck 3-1 to rotate.

[0050] In order to achieve automatic control of glue heating temperature, glue dispensing amount and rivet clamping rotation, a control cabinet 4 is set on one side of the frame 1. The control cabinet 4 is equipped with a PLC control system that is connected to the glue dispensing component 2 and the clamping component 3 respectively.

[0051] Specifically, the PLC control system is electrically connected to the temperature sensor and the heating coil 2-9 respectively, and can control the heating temperature of the heating coil 2-9 according to the glue temperature fed back by the temperature sensor;

[0052] The PLC control system is electrically connected to the air circuit system of the lifting cylinder 2-5, which can realize the height adjustment control of the self-heating glue bucket 2-2;

[0053] The PLC control system is electrically connected to the pneumatic system of the glue-pushing cylinder 2-11, and can be used to control the extension and retraction of the glue-pushing cylinder 2-11 to ensure uniform glue dispensing.

[0054] The PLC control system is electrically connected to the pneumatic system of the pneumatic chuck 3-1, and can be used to control the automatic clamping and loosening of rivets.

[0055] The PLC control system is electrically connected to motor 3-2 and can be used to control the speed and number of revolutions of motor 3-2 to ensure that motor 3-2 rotates at a uniform speed and with a consistent number of revolutions, thereby further improving the uniformity of glue application.

[0056] To facilitate the start and stop control of the glue applicator, a start / stop button 5 is installed on the control cabinet 4.

[0057] Preferably, a temperature display screen can also be installed on the control cabinet 4 to display the real-time temperature of the glue in the glue tank 2-2. When applying glue to the rivets, first, the height of the self-heating glue tank 2-1 is adjusted to the correct position according to the specifications of the rivets. Then, the rivets are clamped on the starting chuck. At the same time, the motor 3-2 drives the pneumatic chuck 3-1 and the rivets to rotate. Then, the glue flows out from the glue outlet 2-15 and is applied to the rivets, thereby achieving uniform glue application on the outer circumference of the rivets.

[0058] This invention not only enables automatic heating of the glue, solving the problem of difficult glue dispensing, but also eliminates the need for hand operation during the glue application process, ensuring consistent and uniform glue dispensing and preventing situations where glue overflow or insufficient glue affects the sealing effect.

[0059] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
