Description

Technical Field

[0001] This utility model relates to the technical field of adhesive coating equipment, specifically an adhesive coating equipment. Background Technology

[0002] Glue application equipment, also known as coating machines, glue scrapers, or automatic glue sprayers, is a type of machinery primarily used to apply liquid glue to workpieces. During screw manufacturing, glue is also applied to the screw threads to form an adhesive layer. After gluing, during installation, the application of a special adhesive increases the friction between the screw and the connecting parts, effectively preventing the screw from loosening.

[0003] However, the above-mentioned device still has the following problems during implementation:

[0004] When applying adhesive to screws, the screws have threads, which can easily create blind spots during the application process. This prevents the adhesive applicator from evenly applying the adhesive to the threaded surface to form a glue layer, thus reducing the effectiveness of the adhesive application. Utility Model Content

[0005] The purpose of this invention is to provide an adhesive coating device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adhesive coating device includes an adhesive coating machine base and an adhesive coating head. The adhesive coating head is drivenly connected to the top of the adhesive coating machine base. A support block is fixedly connected to the top of the adhesive coating machine base. A clamp for holding screws is provided on one side of the support block. A housing is provided on the top of the support block. Two electric heating wires are fixedly installed inside the housing. A transmission mechanism is provided on the top of the adhesive coating machine base.

[0008] The transmission mechanism includes a motor fixedly installed on the top of the glue applicator base, a lead screw fixedly connected to the output end of the motor, a sliding block connected to the surface of the lead screw, a toothed plate fixedly connected to the top of the sliding block, a rotating rod fixedly connected to one side of the clamp, one end of the rotating rod extending through to one side of the support block and fixedly connected to a gear, and the gear and the toothed plate meshing together.

[0009] A blower mechanism is fixedly mounted on one side of the sliding block and can cooperate with the transmission mechanism to generate airflow, blowing the heat generated by the electric heating wire toward the screw.

[0010] Preferably, the blower mechanism includes an air collection box fixedly connected to the top of the glue applicator base. An air inlet pipe is fixedly connected to one side of the air collection box, and a transmission pipe is fixedly connected to the top of the air collection box. One end of the transmission pipe is fixedly connected to one side of the box body. A push block is provided inside the air collection box. A push rod is fixedly connected to one side of the push block. One end of the push rod extends through to one side of the air collection box and is fixedly connected to one side of the sliding block.

[0011] Preferably, a piston plate is fixedly connected to one side of the push block, and the piston plate is made of rubber.

[0012] Preferably, a first one-way valve is fixedly installed on the surface of the intake pipe, and a second one-way valve is fixedly installed on the surface of the transmission pipe.

[0013] Preferably, the top of the glue applicator base is fixedly connected to a guide rail, and the bottom of the sliding block is provided with a guide groove that cooperates with the guide rail.

[0014] Preferably, the clamp is a three-grip chuck.

[0015] Preferably, a bearing is provided on one side of the clamp, and the bearing is rotatably connected to one side of the support block.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model, by setting a transmission mechanism, can fix the screw with a clamp, and then apply glue to the screw with a glue applicator. During the glue application process, the motor is started, which drives the lead screw to rotate. The lead screw will drive the sliding block. Under the constraint of the guide rail and guide groove, the sliding block will move back and forth. The toothed plate will move synchronously with the sliding block. When the toothed plate moves to the right, it will drive the gear to rotate counterclockwise. The gear will drive the rotating rod and the clamp to rotate counterclockwise. At the same time, the screw on the clamp will also rotate synchronously. Then, when the toothed plate moves to the left, the above steps are reversed, and finally the screw will rotate clockwise. By rotating the screw in both directions, the glue can be evenly applied to the surface of the screw, thereby improving the glue application effect.

[0018] 2. By setting up a blower mechanism, this utility model can move the push rod, push block and piston plate synchronously while the sliding block moves back and forth. When the piston plate moves away from the sliding block, it will squeeze the gas in the gas collection box. The gas in the gas collection box passes through the transmission pipe and the box body and blows the heat energy around the electric heating wire onto the screw that is being coated with glue. The wind and heat energy prevent the glue from solidifying quickly, so that it can flow slowly and be evenly coated on the surface of the screw during rotation. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 - Figure 6 This utility model provides a technical solution:

[0028] Example 1:

[0029] An adhesive coating device includes an adhesive coating machine base 1 and an adhesive coating head 2. The adhesive coating head 2 is drivenly connected to the top of the adhesive coating machine base 1. A support block 3 is fixedly connected to the top of the adhesive coating machine base 1. A clamp 4 for clamping screws is provided on one side of the support block 3. A housing 5 is provided on the top of the support block 3. Two electric heating wires 6 are fixedly installed inside the housing 5. A transmission mechanism is provided on the top of the adhesive coating machine base 1.

[0030] The transmission mechanism includes a motor 7 fixedly installed on the top of the glue applicator base 1. A lead screw 8 is fixedly connected to the output end of the motor 7. A sliding block 9 is connected to the surface of the lead screw 8. A toothed plate 10 is fixedly connected to the top of the sliding block 9. A rotating rod 11 is fixedly connected to one side of the clamp 4. One end of the rotating rod 11 extends through to one side of the support block 3 and is fixedly connected to a gear 12. The gear 12 and the toothed plate 10 are meshed together.

[0031] The blower mechanism is fixedly installed on one side of the sliding block 9. It can cooperate with the transmission mechanism to generate airflow and blow the heat generated by the electric heating wire 6 toward the screw.

[0032] In this embodiment, considering that when applying glue to screws, due to the threads on the screw surface, blind spots can easily occur during the glue application process, preventing the glue applicator from evenly applying the glue to the thread surface to form a glue layer, thus reducing the glue application effect, a transmission mechanism is set up. The screw is fixed by the clamp 4, and then glue is applied to the screw by the glue applicator head 2. During the glue application process, the motor 7 is started, driving the lead screw 8 to rotate. The lead screw 8 transmits power to the sliding block 9. Under the constraint of the guide rail 21 and the guide groove 22, the sliding block 9 reciprocates, and the toothed plate 10 moves synchronously with the sliding block 9. (Reference) Figure 2 As shown, when the toothed plate 10 moves to the right, it will drive the gear 12 to rotate counterclockwise. The gear 12 will drive the rotating rod 11 and the clamp 4 to rotate counterclockwise. At the same time, the screw on the clamp 4 will also rotate synchronously. Then, when the toothed plate 10 moves to the left, the steps are reversed, and the screw will eventually rotate clockwise. By rotating the screw in both directions, the glue can be evenly applied to the surface of the screw, thereby improving the glue application effect.

[0033] The top of the glue applicator base 1 is fixedly connected to a guide rail 21, and the bottom of the sliding block 9 is provided with a guide groove 22 that cooperates with the guide rail 21.

[0034] In this embodiment, by setting the guide rail 21 and the guide groove 22, when the lead screw 8 rotates to transmit power to the sliding block 9, the sliding block 9 can be restricted to move only along the trajectory of the guide rail 21, thereby improving its stability during movement.

[0035] Fixture 4 is a three-jaw chuck.

[0036] In this embodiment, by setting a clamp 4, the screw can be fixed by the clamp 4, so that the screw can rotate synchronously with the rotating rod 11.

[0037] A bearing 23 is provided on one side of the clamp 4, and is rotatably connected to one side of the support block 3 through the bearing 23.

[0038] In this embodiment, by setting the bearing 23, the clamp 4 can be supported, and the clamp 4 and the screw can only rotate around the bearing 23, thereby improving the stability during the rotation process.

[0039] Example 2:

[0040] The blower mechanism includes an air collection box 13 fixedly connected to the top of the glue applicator base 1. An air inlet pipe 14 is fixedly connected to one side of the air collection box 13, and a transmission pipe 15 is fixedly connected to the top of the air collection box 13. One end of the transmission pipe 15 is fixedly connected to one side of the box body 5. A push block 16 is provided inside the air collection box 13. A push rod 17 is fixedly connected to one side of the push block 16. One end of the push rod 17 passes through to one side of the air collection box 13 and is fixedly connected to one side of the sliding block 9.

[0041] In this embodiment, by setting up a blower mechanism, the push rod 17, push block 16, and piston plate 18 can move synchronously while the sliding block 9 reciprocates. (Refer to...) Figure 2 and Figure 5 As shown, when the piston plate 18 moves away from the sliding block 9, it will squeeze the gas in the gas collection box 13, so that the gas in the gas collection box 13 passes through the transmission pipe 15 and the box 5, and blows the heat energy around the electric heating wire 6 toward the screw that is being coated with glue. The wind and heat energy prevent the glue from solidifying quickly, so that the screw can flow slowly during rotation and be evenly coated on the surface of the screw.

[0042] It should be noted that when the piston plate 18 moves in the reverse direction to reset, the gas collection box 13 is under negative pressure, and the gas will enter the gas collection box 13 through the air inlet pipe 14.

[0043] A piston plate 18 is fixedly connected to one side of the push block 16. The piston plate 18 is made of rubber.

[0044] In this embodiment, by setting the piston plate 18, a sealed cavity can be formed in the gas collecting box 13 to facilitate the transmission of gas in the gas collecting box 13.

[0045] A first one-way valve 19 is fixedly installed on the surface of the intake pipe 14, and a second one-way valve 20 is fixedly installed on the surface of the transmission pipe 15.

[0046] In this embodiment, a first one-way valve 19 and a second one-way valve 20 are provided. The first one-way valve 19 is a valve that can only allow air to enter the gas collection box 13, and the second one-way valve 20 is a valve that can only allow air to exit the transmission pipe 15. Therefore, when the gas in the gas collection box 13 is compressed, the gas will be discharged through the transmission pipe 15. When the gas collection box 13 is under negative pressure, the gas will enter through the air inlet pipe 14.

[0047] Working principle: The user fixes the screw using clamp 4, and then applies glue to the screw using glue applicator 2. During the glue application process, motor 7 is started, driving lead screw 8 to rotate. Lead screw 8 transmits power to sliding block 9. Under the constraint of guide rail 21 and guide groove 22, sliding block 9 reciprocates. Tooth plate 10 moves synchronously with sliding block 9. (See reference) Figure 2 As shown, when the toothed plate 10 moves to the right, it will drive the gear 12 to rotate counterclockwise. The gear 12 will drive the rotating rod 11 and the clamp 4 to rotate counterclockwise. At the same time, the screw on the clamp 4 will also rotate synchronously. Then, when the toothed plate 10 moves to the left, the steps are reversed, and the screw will eventually rotate clockwise. By rotating the screw in both directions, the glue can be evenly applied to the surface of the screw, thereby improving the glue application effect.

[0048] As the sliding block 9 reciprocates, the push rod 17, the push block 16, and the piston plate 18 move synchronously. (Refer to...) Figure 2 and Figure 5 As shown, when the piston plate 18 moves away from the sliding block 9, it will squeeze the gas in the gas collection box 13, so that the gas in the gas collection box 13 passes through the transmission pipe 15 and the box body 5, and blows the heat energy around the electric heating wire 6 toward the screw that is being coated with glue. The wind and heat energy prevent the glue from solidifying quickly, so that the glue can flow slowly and be evenly coated on the surface of the screw during rotation.

[0049] It should be noted that the electric heating wire 6 and the motor 7 are existing devices or equipment, or devices or equipment that can be implemented with existing technology, and the specific composition and principle of the power supply of the electric heating wire 6 and the motor 7 are clear to those skilled in the art, so they will not be described in detail here.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
