Description

Technical Field

[0001] The utility model relates to a production device for electrothermal equipment, in particular to a gluing and pressing device for a graphite electrothermal plate. Background Technique

[0002] The graphite electrothermal plate is a kind of electrothermal equipment. It uses graphite material as the heating material, uses materials such as cloud plates as the insulating materials, and has a heat-conducting plate made of materials such as stainless steel covered on the outer layer as the bottom plate.

[0003] The materials required for making the graphite electrothermal plate include the bottom plate, graphite sheets, insulating glue, etc. The manufacturing process is as follows:

[0004] 1. Clean the iron or stainless-steel bottom plate and dry the moisture.

[0005] 2. Apply a layer of insulating glue on the bottom plate.

[0006] 3. Cover the graphite sheets on the insulating glue layer on the bottom plate (the bottom plate is slightly larger than the graphite sheets).

[0007] 4. Level and press the graphite sheets and the bottom plate so that the graphite sheets are firmly adhered to the bottom plate through the insulating glue layer.

[0008] 5. Remove the glue overflowing from the surroundings and cut off the excess bottom plate material along the periphery of the graphite sheets.

[0009] 6. Perform drying and curing treatment on the insulating glue layer.

[0010] 7. Weld the wires to the formed graphite electrothermal plate with an electric soldering iron.

[0011] At present, in the industrial production of graphite electrothermal plates, basically multiple servo power devices (such as servo motors, servo cylinders, hydraulic cylinders) cooperate with each other (controlled by an industrial PLC mainframe) to realize the discharging, bonding and pressing, and conveying of graphite sheets.

[0012] Since a large number of intelligent control units are used for mutual communication in each servo device, in extreme working conditions (such as overheating under long-term operation), among many intelligent control, induction, and transceiver modules, it is inevitable that individual module signal conduction is delayed, mis-conducted, and the response is not timely, and finally there is a cooperation deviation, resulting in a large number of unqualified products produced during the period.

Specific embodiments

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0044] Please refer to Figures 1 - 10 , as an embodiment of the present invention, the gluing and pressing device for graphite electric heating plates includes a truss 1, a conveyor belt 2 that can operate intermittently is arranged on the truss 1, and a plate bin 11 is arranged above the conveyor belt 2, and the plate bin 11 is connected to the truss 1;

[0045] A plate ejection slot 1101 is provided at the bottom of the plate bin 11 along the running direction of the conveyor belt 2, and a plate ejection structure is provided on the side of the plate bin 11 away from the running direction of the conveyor belt 2, and the plate ejection structure is used to eject the graphite sheets at the bottom of the plate bin 11 from the plate bin 11 one by one;

[0046] The plate discharging structure cooperates with the conveyor belt 2. When the conveyor belt 2 is intermittently stationary, the plate discharging structure pushes out the graphite sheets at the bottom of the plate bin 11. When the conveyor belt 2 is intermittently conveying, the plate discharging structure retreats and resets.

[0047] A pressing plate 17 is provided on the side of the board bin 11 away from the board discharging structure, and the pressing plate 17 is connected to a tripod 22 fixed on the board bin 11 through an elastic energy storage structure, and the elastic energy storage structure cooperates with the board discharging structure;

[0048] After the plate-discharging structure pushes out the graphite sheet at the bottom of the plate bin 11, the elastic energy storage structure releases elastic potential energy and drives the pressing plate 17 to press down; and during the process of the plate-discharging structure retreating and resetting, the elastic energy storage structure increases elastic potential energy and drives the pressing plate 17 to rise.

[0049] In this embodiment, in the utility model, by establishing a mutually coordinated logical action relationship between the plate discharging structure, the conveyor belt 2, and the pressing plate 17, the graphite sheet can be adhered and bonded one by one with the bottom plate placed on the conveyor belt 2. The various structures cooperate closely with each other, the operation is stable, and the environmental factors are not significantly affected, which can ensure that the production error is within a reasonable range.

[0050] When the device is in operation, firstly, a plurality of bottom plates of the electric heating plates need to be placed on the conveyor belt 2 at equal intervals, and glue is applied on the upward side of the bottom plates; when the bottom plates are conveyed between the pressing plate 17 and the plate bin 11 by the conveyor belt 2, a graphite sheet falls from the plate bin 11, and the graphite sheet falls on the bottom plates; then the conveyor belt 2 is operated, so that the graphite sheet and the bottom plates are conveyed together under the pressing plate 17, and the elastic potential energy is released by the elastic energy storage structure to drive the pressing plate 17 to be pressed down, so that the graphite sheet and the bottom plates are tightly attached together, and the two are firmly adhered with the help of glue to form a graphite electric heating plate.

[0051] As a further solution of the utility model, two groups of conveying shafts 9 are rotatably arranged on the truss 1, the two groups of conveying shafts 9 are located at both ends of the truss 1, and each group of conveying shafts 9 is provided with a conveying roller 10;

[0052] The conveyor belt 2 is tensioned and rolls between two sets of the conveyor rollers 10. Beam frames are respectively arranged on both sides of the truss 1. A speed reducer and a motor 3 are installed on one of the beam frames. The output end of the motor 3 is connected to the input shaft of the speed reducer, and the output shaft of the speed reducer is connected to one end of the conveyor shaft 9 through a Maltese cross mechanism assembly.

[0053] In this embodiment, when the motor 3 operates, the output end of the motor 3 drives the input shaft of the speed reducer to run, and speed reduction transmission is achieved between the input shaft and the output shaft of the speed reducer. The speed reducer is an application of the prior art, such as a worm and worm gear speed reducer, a gear speed reducer, etc., which will not be elaborated here. The output shaft of the speed reducer drives one conveyor shaft 9 to rotate through the Maltese cross mechanism assembly, and this conveyor shaft 9 drives the other conveyor shaft 9 to rotate through the conveyor belt 2, finally realizing the stable and intermittent slow-speed operation of the conveyor belt 2.

[0054] During the entire production and manufacturing process, the pressing speed is not too fast, so a speed reducer is needed to achieve the speed reduction transmission between the motor 3 and the conveyor belt 2; by using the Maltese cross mechanism assembly, the continuous movement of the motor 3 is converted into the intermittent operation of the conveyor belt 2.

[0055] As a further solution of the present invention, the Maltese cross mechanism assembly includes a driving wheel 4 and a driven wheel 5 rotatably arranged on the truss 1, and the driven wheel 5 is also rotatably arranged on the truss 1;

[0056] The Maltese cross mechanism assembly is also an application of the prior art, and its detailed structure will not be elaborated here.

[0057] Wherein, the driving wheel 4 is connected to the output shaft of the speed reducer, a large belt pulley 6 is coaxially connected to the driven wheel 5, a small belt pulley 8 is arranged at one end of the conveyor shaft 9, and the small belt pulley 8 and the large belt pulley 6 are connected by a transmission belt 7.

[0058] In this embodiment, the output shaft of the speed reducer drives the driving wheel 4 to rotate continuously, and the driving wheel 4 drives the driven wheel 5 to rotate intermittently; the driven wheel 5 drives the large belt pulley 6 to rotate synchronously and intermittently, and finally drives the small belt pulley 8 and the conveyor shaft 9 to rotate intermittently under the action of the transmission belt 7, so that the conveyor belt 2 can operate intermittently.

[0059] As a further solution of the present invention, the plate discharging structure includes a crankshaft 14 rotatably arranged above the truss 1. A bending part is formed at the middle bending part of the crankshaft 14. One end of the bending part is rotatably connected to one end of a connecting rod 13, and the other end of the connecting rod 13 is rotatably connected to one end of a push plate 12;

[0060] The other end of the push plate 12 passes through the notch 1101 of the discharge plate and is in sliding fit with the bottom of the cartridge 11. A connecting shaft 16 is provided on the driving wheel 4, and one end of the connecting shaft 16 is connected to one end of the crankshaft 14 through a first synchronous belt 15.

[0061] In this embodiment, during the continuous rotation of the driving wheel 4, the connecting shaft 16 is driven to rotate. The connecting shaft 16 then drives the crankshaft 14 to rotate by means of the first synchronous belt 15. The crankshaft 14 uses the connecting rod 13 to drive the push plate 12 to perform a reciprocating linear motion.

[0062] Multiple graphite sheet plates are stacked in the cartridge 11. When the push plate 12 moves linearly to approach the end of the stroke of the crankshaft 14 (i.e., at the end position of the return stroke of the push plate 12), the foremost edge of the push plate 12 is flush with the side wall of the cartridge 11. At this time, the lowermost graphite sheet plate in the cartridge 11 falls to the bottom of the cartridge 11. Then, the push plate 12 moves in a direction away from the crankshaft 14, and completely pushes out the graphite sheet plate that has fallen to the bottom of the cartridge 11 from the cartridge 11. In this way, the push plate 12 can be used to push out the stacked graphite sheet plates in the cartridge 11 one by one from the cartridge 11.

[0063] As a further solution of the present invention, the elastic energy storage structure includes a rotating shaft 20 rotatably provided above the truss 1. One end of the rotating shaft 20 is provided with a gear 21. Part of the outer peripheral surface of the gear 21 has continuous teeth, and the other part is smooth and toothless.

[0064] The toothed part on the gear 21 is adapted to a toothed plate 24. The toothed plate 24 is fixed on a guide frame 23. The guide frame 23 is in sliding fit with the tripod 22.

[0065] The guide frame 23 is also fixed to a pressing plate 17. A sliding rod 25 is provided on the pressing plate 17. The sliding rod 25 is also in sliding fit with the tripod 22. A spring 26 is provided between the tripod 22 and the pressing plate 17. One end of the spring 26 abuts against the tripod 22, and the other end abuts against the pressing plate 17. The rotating shaft 20 is connected to the crankshaft 14 through a second synchronous belt 19.

[0066] In this embodiment, during the rotation of the crankshaft 14, the second synchronous belt 19 drives the rotation of the rotating shaft 20, and the rotating shaft 20 drives the rotation of the gear 21; when the toothed part on the gear 21 cooperates with the toothed plate 24, the rotating gear 21 can drive the toothed plate 24 and the guide frame 23 fixed to the toothed plate 24 to slide upward; the guide frame 23 drives the pressing plate 17 and the slide rod 25 to slide upward, so that the spring 26 between the tripod 22 and the pressing plate 17 is further compressed; after the toothed part on the gear 21 is separated from the toothed plate 24, the elastic potential energy is released by the spring 26 to drive the slide rod 25, the pressing plate 17, the guide frame 23, and the toothed plate 24 to move downward quickly together, and the graphite sheet plate falling on the bottom plate is tightly pressed and adhered to the bottom plate through the adhesive.

[0067] As a further solution of the present invention, in order to ensure that the conveyor belt 2 does not deform during the pressing and bonding of the graphite sheet plate and the bottom plate; a support table 18 is further provided on the truss 1, the upper surface of the support table 18 fits with the lower surface of the upper layer of the conveyor belt 2, and the support table 18 faces the pressing plate 17.

[0068] In this embodiment, due to the supporting effect of the support table 18, when the pressing plate 17 presses and bonds the graphite sheet plate and the bottom plate, the downward force received by the bottom plate is transmitted to the support table 18 through the conveyor belt 2, ensuring that the conveyor belt 2 and the bottom plate and graphite sheet plate on the conveyor belt 2 will not tilt or vibrate.

[0069] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of the present invention, all technical solutions that can implement the present invention in other specific forms are included in the present invention.
