Description

Technical Field

[0001] The present invention relates to the field of plastic product processing, and more particularly to an automatic assembly device for plastic products. Background Art

[0002] Plastic products are a general term for household and industrial products made primarily from plastic. This includes products made using all processes, including injection molding and blister molding. Plastics are a class of synthetic polymers with plasticity. Along with synthetic rubber and synthetic fibers, plastics form one of the three most essential synthetic materials in our daily lives.

[0003] In the prior art, plastic products are connected in a variety of ways, primarily including snap-fit ​​assembly, screw fastening, and adhesive connections. When using adhesive connection, the typical steps include: securing the components to be bonded using a fixture, applying adhesive to the bonding surface of one component, pressing the two components together, and finally allowing the adhesive to cure to complete the bonding.

[0004] However, adhesive bonding processes have drawbacks: uneven adhesive distribution during application can lead to localized excess adhesive being squeezed out of the bonding interface during the subsequent lamination process, while insufficient adhesive can leave gaps or thinner adhesive layers in other areas. These uneven adhesive layers and adhesive deficiencies significantly reduce the effective bonding area and bond strength, ultimately reducing the quality and reliability of the bond.

[0005] Therefore, a plastic product automatic assembly device is proposed. Summary of the Invention

[0006] In view of the problems existing in the prior art, the purpose of the present invention is to provide an automated assembly device for plastic products, which can evenly apply glue to avoid uneven glue layer thickness and glue shortage.

[0015] Furthermore, the conveyor belt includes two rotating rollers, a stepper motor, and a conveyor belt. The two rotating rollers are rotatably mounted on the operating table; the conveyor belt is sleeved on the outside of the two rotating rollers, and the output end of the stepper motor is fixedly connected to the rotating shaft of one of the rotating rollers.

[0016] Nuts are evenly embedded on the conveyor belt, and a threaded rod matched with the thread of the nut is fixedly installed on the bottom wall of the fixing frame.

[0017] Furthermore, the downward movement mechanism includes magnets evenly fixedly mounted on the conveyor belt, the magnets are spaced apart from the fixing frame, and the shovel plate is made of a magnetic material that is attracted to the magnets.

[0018] Furthermore, a socket is provided on the top wall of the installation groove, and a guide rod is vertically slidably inserted into the socket. The bottom end of the guide rod is fixedly connected to the shovel plate, and an elastic rope is installed between the top wall of the shovel plate and the top wall of the installation groove.

[0019] Furthermore, an air hole is obliquely opened on the top wall of the shovel plate, and the air hole passes through the bottom wall of the shovel plate.

[0020] Furthermore, a cavity is opened on the corrugated pipe, a conduit is inserted into the side wall of the cavity, the end of the conduit away from the cavity extends into the installation groove, and a blocking block is fixedly installed on the top wall of the shovel plate, and the blocking block is used to block the bottom end of the conduit.

[0021] Furthermore, an air intake valve and an air exhaust valve are embedded on the side wall of the cavity, and the conduit is fixedly installed on the output end of the exhaust valve.

[0026] (2) In this solution, with the cooperation of the shovel plate and the sealing block, when the shovel plate is extended from the installation groove, the sealing block is separated from the conduit. At this time, the gas in the cavity passes through the exhaust valve and flows along the conduit into the installation groove and is discharged through the air hole. In this process, the gas discharged from the air hole impacts the adhesive remaining on the side wall of the coating port, accelerates the curing rate of the adhesive, ensures that the adhesive remaining on the side wall of the coating port can be scraped off by the shovel plate, and improves the cleaning effect of the side wall of the coating port.

[0027] (3) In this solution, with the cooperation of the elastic member, the sliding rod and the sealing plate, the bottom wall of the sealing plate is always in contact with the bottom wall of the collecting tank. During the movement of the push plate, the sealing plate rubs against the surface of the collecting tank, and the temperature of the sealing plate and the collecting tank are increased by friction. Under the action of heat exchange, the glue in the collecting tank is heated, which increases the fluidity of the glue and ensures that the glue can flow to the coating port in a timely manner.

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only 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 ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] See also Figures 1 to 7 , an automated assembly device for plastic products, comprising an operating table 1;

[0039] A conveyor belt 2 and a first telescopic rod 3 with the output end facing upward are provided on the top wall of the operating table 1;

[0040] The surface of the conveyor belt 2 is evenly provided with fixing frames 4, and the top wall of the fixing frames 4 is provided with a card slot 5, which cooperates with the workpiece to be assembled. The workpiece to be assembled is placed in the card slot 5 to prevent the workpiece from shaking;

[0041] A pressing plate 6 is fixedly mounted on the output end of the first telescopic rod 3, a collecting groove is provided on the top wall of the pressing plate 6, and a coating port 7 is provided on the bottom wall of the pressing plate 6, the top end of which is connected to the collecting groove;

[0042] A push plate 8 is vertically slidably installed in the collection tank. A driving mechanism for driving the push plate 8 to move along the bottom wall of the collection tank is provided on the pressure plate 6. A sealing plate 9 is horizontally installed on the side wall of the push plate 8 to cooperate with the coating port 7; and the sealing plate 9 is slidably engaged with the bottom wall of the collection tank;

[0043] A mounting groove is provided on the bottom wall of the blocking plate 9 , in which a shovel plate 10 is slidably installed. The shovel plate 10 cooperates with the coating port 7 , and a downward movement mechanism is provided on the pressing plate 6 for driving the shovel plate 10 to move along the side wall of the coating port 7 .

[0044] The driving mechanism includes a mounting plate 11 fixedly mounted on the top wall of the pressure plate 6. The mounting plate 11 covers the surface of the collection tank. The installation of the mounting plate 11 can prevent the glue in the collection tank from being exposed to the air, thereby preventing the glue from solidifying. An electric slide rail 12 is fixedly mounted horizontally on the bottom wall of the mounting plate 11. A slider 13 is slidably mounted on the electric slide rail 12. The slider 13 is fixedly connected to the push plate 8 and is driven to move by the electric slide rail 12, thereby driving the push plate 8 to move. The slider 13 is slidably mounted on the electric slide rail 12, and the movement of the slider 13 along the electric slide rail 12 is a prior art and will not be described in detail. A bellows 14 is fixedly mounted on the side wall of the slider 13 away from the sealing plate 9. The bellows 14 is sleeved on the electric slide rail 12, and the end of the bellows 14 away from the slider 13 is fixedly connected to the end of the electric slide rail 12. Therefore, when the push plate 8 pushes the glue and causes the glue to shake, it can prevent the glue from splashing onto the connection between the slider 13 and the electric slide rail 12, thereby ensuring that the electric slide rail 12 can work normally.

[0045] In the initial state, the first telescopic rod 3 is in an extended state, and the blocking plate 9 covers the surface of the coating port 7 , and adhesive is installed in the space between the push plate 8 and the collecting tank on the side away from the blocking plate 9 .

[0046] During operation, the workpiece is first placed in the card slot 5 , and then the conveyor belt 2 is started, and the workpiece is driven to move to the bottom of the pressing plate 6 via the conveyor belt 2 and the fixing frame 4 .

[0047] When the workpiece moves to the designated position directly below the pressing plate 6, the first telescopic rod 3 is activated. At this time, the output end of the first telescopic rod 3 contracts, thereby driving the pressing plate 6 to move downward until the bottom wall of the pressing plate 6 is tightly fitted with the top wall of the workpiece.

[0048] Then the electric slide rail 12 is started, and the push plate 8 is driven to move through the slider 13 until the blocking plate 9 and the push plate 8 are both out of contact with the coating port 7. During this process, the adhesive in the collection tank flows into the coating port 7, so that a certain amount of adhesive can be evenly applied to the surface of the top wall of the workpiece.

[0049] After adhesive coating is complete, electric slide rail 12 drives slider 13 back to its original position. Adhesive overflowing from coating port 7 is pushed away by push plate 8, and blocking plate 9 seals coating port 7, preventing the adhesive from entering the space in the collection tank located on the side of push plate 8 near blocking plate 9. Once blocking plate 9 seals coating port 7 again, first telescopic rod 3 extends, driving pressure plate 6 out of contact with the workpiece.

[0050] Therefore, with the cooperation of the pressing plate 6, the coating port 7 and the conveyor belt 2, a fixed amount of adhesive can be automatically coated on the part of the workpiece to be bonded, which improves the bonding effect during subsequent processing.

[0051] When the coating is completed and the conveyor belt 2 drives the coated workpiece to move, the downward movement mechanism drives the shovel plate 10 to move downward along the side wall of the coating port 7, thereby scraping off the adhesive on the side wall of the coating port 7 to prevent the adhesive from agglomerating on the side wall of the coating port 7.

[0052] like Figure 2 As shown, the conveyor belt 2 includes two rotating rollers 201, a stepper motor 202 fixedly mounted on the operating table 1, and a conveyor belt 203. The two rotating rollers 201 are both rotatably mounted on the operating table 1, and the two rotating rollers 201 are parallel to each other; the conveyor belt 203 is sleeved on the outside of the two rotating rollers 201, and the output end of the stepper motor 202 is fixedly connected to the rotating shaft of one of the rotating rollers 201; therefore, the moving speed of the conveyor belt 203 can be controlled by the stepper motor 202; and the stepper motor 202 is a prior art and will not be described in detail; and by setting the stepper motor 202, the conveyor belt 2 can drive the workpiece to move accurately to the bottom of the pressure plate 6, thereby ensuring that the glue can be evenly applied.

[0053] Nuts 15 are evenly embedded on the conveyor belt 203, and a threaded rod 16 that cooperates with the thread of the nut 15 is fixedly installed on the bottom wall of the fixing frame 4. The fixing frame 4 can be disassembled through the mutual cooperation between the nut 15 and the threaded rod 16. Therefore, when processing workpieces of different models, different fixing frames 4 can be replaced, thereby expanding the scope of application of the device.

[0054] like Figure 3 As shown, the downward movement mechanism includes magnets 17 evenly fixedly mounted on the conveyor belt 203 , the magnets 17 are spaced apart from the fixing frame 4 , and the shovel plate 10 is made of a magnetic material that attracts the magnets 17 .

[0055] When the conveyor belt 203 transfers the workpiece that has been coated with adhesive, the magnet 17 moves under the shovel plate 10. At this time, under the attraction of the magnet 17, the shovel plate 10 moves downward, thereby driving the shovel plate 10 to move along the side wall of the coating port 7.

[0056] like Figure 3 As shown, a socket is provided on the top wall of the mounting groove, and a guide rod 18 is vertically slidably inserted into the socket. The bottom end of the guide rod 18 is fixedly connected to the shovel plate 10, so that the moving direction of the shovel plate 10 can be limited by the guide rod 18, and an elastic rope 19 is installed between the top wall of the shovel plate 10 and the top wall of the mounting groove. When the shovel plate 10 is extended from the mounting groove, the elastic rope 19 is stretched; when the magnet 17 is away from the shovel plate 10, the elastic rope 19 recovers and drives the shovel plate 10 to retract into the mounting groove, ensuring that the blocking plate 9 can move normally.

[0057] like Figure 6 As shown, an air hole 20 is obliquely opened on the top wall of the shovel plate 10 , and the air hole 20 passes through the bottom wall of the shovel plate 10 .

[0058] A cavity 21 is provided on the bellows 14 , and a conduit 22 is inserted into the side wall of the cavity 21 . The end of the conduit 22 away from the cavity 21 extends into the mounting groove. A blocking block 23 is fixedly mounted on the top wall of the shovel plate 10 , and the blocking block 23 is used to block the bottom end of the conduit 22 .

[0059] An air inlet valve 24 and an air exhaust valve 25 are embedded on the side wall of the cavity 21, and the conduit 22 is fixedly mounted on the output end of the exhaust valve 25. When the shovel 10 is located in the mounting groove, the blocking block 23 is inserted into the bottom end of the conduit 22, and the gas in the cavity 21 cannot be discharged.

[0060] When the shovel plate 10 is extended from the mounting groove, the blocking block 23 is out of contact with the conduit 22. At this time, the gas in the cavity 21 passes through the exhaust valve 25 and flows along the conduit 22 into the mounting groove and is discharged through the air hole 20. During this process, the gas discharged from the air hole 20 impacts the adhesive remaining on the side wall of the coating port 7, accelerates the curing rate of the adhesive, ensures that the adhesive remaining on the side wall of the coating port 7 can be removed by the shovel plate 10, and improves the cleaning effect of the side wall of the coating port 7.

[0061] like Figure 3 As shown, the blocking block 23 is made of rubber, and the ratio of the diameter of the blocking block 23 to the bottom diameter of the conduit 22 is 1.5-2, thereby ensuring the sealing effect of the conduit 22, preventing premature leakage of gas, and ensuring that the adhesive can be evenly distributed on the surface of the workpiece.

[0062] like Figure 3 As shown, a slide groove is provided on the side wall of the push plate 8, and a slide rod 26 is slidably installed in the slide groove. An elastic member 27 is installed between the slide rod 26 and the top wall of the slide groove. Under the action of the elastic member 27, the slide rod 26 has a tendency to move downward, and the blocking plate 9 is horizontally fixed on the side wall of the slide rod 26, and the bottom wall of the blocking plate 9 and the bottom wall of the push plate 8 are in the same plane; therefore, under the action of the elastic member 27, the bottom wall of the blocking plate 9 is always in contact with the bottom wall of the collecting tank. During the movement of the push plate 8, the blocking plate 9 rubs on the surface of the collecting tank, and the friction increases the temperature of the blocking plate 9 and the collecting tank. Under the action of heat exchange, the glue in the collecting tank is heated, the fluidity of the glue is increased, and the glue is ensured to flow to the coating port 7 in time.

[0063] Instructions for use: In the initial state, the first telescopic rod 3 is in an extended state, and the blocking plate 9 covers the surface of the coating port 7, and the space between the push plate 8 and the collecting tank away from the blocking plate 9 is filled with adhesive.

[0064] During operation, the workpiece is first placed in the card slot 5 , and then the conveyor belt 2 is started, and the workpiece is driven to move to the bottom of the pressing plate 6 via the conveyor belt 2 and the fixing frame 4 .

[0065] When the workpiece moves to the designated position directly below the pressing plate 6, the first telescopic rod 3 is activated. At this time, the output end of the first telescopic rod 3 contracts, thereby driving the pressing plate 6 to move downward until the bottom wall of the pressing plate 6 is tightly fitted with the top wall of the workpiece.

[0066] Then start the electric slide rail 12, and drive the push plate 8 to move through the slider 13 until the sealing plate 9 and the push plate 8 are out of contact with the coating port 7. During this process, the adhesive in the collection tank flows into the coating port 7, so that a certain amount of adhesive can be evenly applied to the surface of the top wall of the workpiece.

[0067] When the adhesive coating is completed, the electric slide rail 12 drives the slider 13 to reset. At this time, the adhesive overflowing from the coating port 7 is pushed by the push plate 8, and the sealing plate 9 blocks the coating port 7, thereby preventing the adhesive from entering the space in the collection tank located on the side of the push plate 8 close to the sealing plate 9. Until the sealing plate 9 blocks the coating port 7 again, the first telescopic rod 3 extends and drives the pressure plate 6 to break contact with the workpiece.

[0068] Therefore, with the cooperation of the pressing plate 6, the coating port 7 and the conveyor belt 2, a fixed amount of adhesive can be automatically coated on the part of the workpiece to be bonded, which improves the bonding effect during subsequent processing.

[0069] When the coating is completed and the conveyor belt 2 drives the coated workpiece to move, the downward movement mechanism drives the shovel plate 10 to move downward along the side wall of the coating port 7, thereby scraping off the adhesive on the side wall of the coating port 7 to prevent the adhesive from agglomerating on the side wall of the coating port 7.

[0070] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
