Description

Automatic glue spraying device of PTC heating pipe glue spraying machine

technical field

The invention belongs to the technical field of special devices for manufacturing PTC heaters, and specifically relates to an automatic glue spraying device of a PTC heating pipe glue spraying machine, which is used for spraying adhesive on the surface of the PTC heating pipe facing the heat dissipation aluminum sheet, so that the heat dissipation aluminum sheet It is fixed with the PTC heating tube by means of adhesive.

Background technique

The aforementioned PTC heating tube is a part of the structural system of the PTC heater (also called "PTC heater" in the industry, the same below). Specifically, the PTC heater is mainly composed of the following four parts: one is the heating body, the The heating body is also called the radiator; the second is the PTC heating core; the third is the tailstock; the fourth is the electrical connection support seat. The heating body includes a PTC heating tube and a corrugated heat dissipation aluminum sheet (also called a heat dissipation strip, the same below) positioned on the corresponding two sides of the PTC heating tube in the length direction. The PTC heating core is accommodated in the lumen of the PTC heating tube, including a plurality of neatly arranged PTC thermistors (Positive Temperature Coefficient Ceramic thermistor) and one electrode sheet (also called electrical connection strip) arranged on both sides of the PTC thermistor in electrical contact with the electrode layer. One end of the PTC heating tube is fixed with the tailstock together with the PTC heating core (fixed with the tailstock by inserting), while the other end of the PTC heating tube is fixed together with the PTC heating core and the electrical connection support (supported by the electrical connection by inserting seat fixed). The aforesaid electrode sheets (a pair) are electrically controlled and connected to the external power controller by the circuit after passing through the electrical connection support base. Under the control of the power controller, for example, when the electrode sheet is energized, the PTC thermistor generates heat and transfers the heat to the PTC heating tube, and the heat of the PTC heating tube is dissipated by the cooling aluminum sheet.

PTC heaters with the above-mentioned structure are widely used in air conditioners, especially wall-mounted air conditioners or similar devices, and are widely seen in published Chinese patent documents, such as the "PTC heater kit" recommended by CN2640002Y for example , "Combined PTC heating device" provided by CN2753090Y, "A heat-conducting aluminum tube and PTC heater of a PTC heater" introduced by CN201499328U and "PTC heater" disclosed by CN2392334Y, "PTC heater" disclosed by CN103874249A and CN104053255A Announced "PTC heater" and so on.

The aforementioned heat dissipation aluminum sheet is usually adhered to the outside of the tube wall of the PTC heating tube by means of an adhesive, specifically: first, the adhesive is applied on the tube walls (outer walls) of the PTC heating tube facing each other and along the length direction of the PTC heating tube , and then glue the heat dissipation aluminum sheet on the tube wall.

In the prior art, there are two main ways to form an adhesive layer on the pipe wall of the PTC heating pipe: one is to brush the adhesive for fixing the heat dissipation aluminum sheet to the pipe wall by a worker with a brush or similar tools; The adhesive is attached to the pipe wall by screen printing. The former of these two methods has at least the following shortcomings: one, the labor intensity of the workers is high; It is related to experience, sense of responsibility and even emotions; Fourth, because the adhesive has a pungent smell, it will affect the health of workers to a certain extent. The latter can make up for the lack of manual brushing by screen printing, but because the surface of the PTC heating tube facing the heat dissipation aluminum sheet is not flat, but has an insertion groove for matching the two sides of the heat dissipation aluminum sheet , that is, through the insertion grooves formed on the tube wall of the PTC heating tube and located on both sides of the length direction, the positioning effect of the embedded aluminum sheet is improved, so the tube wall of the PTC heating tube is printed by screen printing When the adhesive is used, the part of the inserting groove often has whitening phenomenon because the adhesive cannot be obtained, which affects the overall bonding effect of the heat dissipation aluminum sheet and the tube wall of the PTC heating tube. Therefore, the heat of the PTC heating tube is not enough to be fully and effectively dissipated by the aluminum sheet. Transfer and dissipate, resulting in energy waste, that is, the heating efficiency of the air conditioner is affected. In order to eliminate the above-mentioned whitening phenomenon of screen printing, full-time workers are usually assigned to fill the above-mentioned inserting groove with a brush. On the one hand, it adds valuable labor resources, and on the other hand, it puts the manufacturers of PTC heaters in a dilemma, that is, it is impossible to find a solution between manual gluing and screen printing that not only satisfies the quality of gluing, but also improves the efficiency of gluing and ensures less stress. The ideal balance point of labor intensity of workers.

For the purpose of solving the above technical problems, the applicant conducted a literature search and retrieved the "PTC electric heating element automatic gluing device" recommended by the authorized announcement number CN101879494B. And a glue container is set at the position corresponding to the top of the glue roller, the glue container feeds the adhesive to the glue roller, when the electrode strip passes between the glue roller and the supporting roller, the glue on it The adhesive is transferred to the electrode strip, and when the glued electrode strip goes out between the gluing roller and the supporting roller and arrives at the workbench, the air suction hole (equipped with a suction nozzle) set on the workbench Absorb excess adhesive from electrode strips. The invention patent scheme can objectively fulfill the technical effect recorded in paragraph 0007 of its specification, but it has no inspiration for the gluing of the PTC heating tube, because the electrode strip is solid and can withstand the corresponding pressure, while the PTC heating tube The wall thickness of the PTC heating tube is usually below 2 mm, or even below 1.5 mm (see paragraph 0019 of the aforementioned CN201499328U specification), and because the lumen of the PTC heating tube needs to be provided with the aforementioned PTC heating core, it is hollow, so if If it is glued by roller coating, that is, by contact, it will inevitably cause deformation. Especially as mentioned above, since the two sides of the PTC heat pipe form slots for mating the heat dissipation aluminum sheets, the glue roller cannot transfer the adhesive to the slots.

It can be seen from the above description that the above technical problems can only be solved by spraying the adhesive to the PTC heating tube with a glue spraying device with a reasonable structure and in a non-contact state with the PTC heating tube. However, in the patents and non-patent documents disclosed so far There is no corresponding technical inspiration. Therefore, the applicant has made positive and beneficial designs, finally formed the technical scheme to be introduced below, and has carried out a simulation test in the applicant's laboratory under confidentiality measures, and the result proves that it is practicable.

The specific action process is as follows:

The on-line operator operates the electrical box 10 to make the PTC heating tube automatic glue sprayer enter the working state. Under the operation of the driving motor 21 of the power mechanism 2, the output shaft 221 of the driving reduction box 22 drives the PTC. The gear box output shaft sprocket 59 of the structural system of the heating pipe conveying mechanism 5 drives the drive sprocket 57 through the drive chain 58. Since the drive sprocket 57 is fixed on the drive sprocket shaft 51, the drive sprocket 57 drives the drive sprocket shaft. 51 rotation, and because a group of driving sprockets 53 are fixed on the driving sprocket shaft 51, thereby driving a group of driving sprockets 53 to rotate by the driving sprocket shaft 51, and also because the two ends of the conveying chain 55 are respectively placed in the main and driven On the sprockets 53 and 54, the driving sprocket 56 drives the driven sprocket 54 through the conveying chain 55, and the driven sprocket shaft 52 is driven by the driven sprocket 54, so that the conveying chain 55 is in a moving state.

Since the acting cylinder column 611 is connected with the downward side of the floating plate 62, thus The floating plate 62 is pushed up by the working cylinder column 611, that is, the floating plate 62 floats upward (rising) along the guide column 622, and because the front and rear lifting frames 63 and 64 of a group of PTC heating tubes are fixed on the floating on the plate 62, so when the floating plate 62 floats, under the synergistic (joint) action of a group of PTC heating tube front lifting frames 63 and a group of PTC heating tube rear lifting frames 64, the former position of the PTC heating tube The PTC heating tube 81 on the carrying arm 551 is lifted upwards from the PTC heating tube carrying arm 551, and each PTC heating tube in a group (three in this embodiment) of PTC heating tubes in the front and rear support frames 63, 64 Two PTC heating tubes 81 are allocated to the front and rear lifting frames, so there are six PTC heating tubes 81 in the state of being suspended from the PTC heating tube carrying arm 551 . Taking Figure 2 as an example, among the aforementioned six PTC heating tubes 81, the two PTC heating tubes 81 on the right correspond exactly to the bottom of the front glue spray nozzles 34 (a pair) of the PTC heating tubes, and the one on the left The two PTC heating tubes 81 (the front side glue spraying has been completed) correspond exactly to the bottom of the PTC heating tube back glue spray nozzle 44 (a pair), and the two PTC heating tubes 81 in the middle (the front side glue spraying has been completed) It just corresponds to the position of a pair of rotary clamping cylinders 75 of the PTC heating tube turning mechanism 7 . Then just spray glue on the PTC heating pipe 81 by the glue spraying nozzle 34 on the front of the PTC heating pipe, specifically: the glue is supplied to the front and back glue spraying nozzles 34, 44 of the PTC heating pipe by the adhesive supply mechanism (not shown in the figure) through the pipeline At the same time, transmission motor 35 works, the transition drive shaft 36 is driven by the motor shaft, the front drive wheel 37 is driven by the transition drive shaft 36, the rear drive wheel 38 is driven by the front drive wheel 37 through the drive wheel drive belt 39, and the movement of the drive wheel drive belt 39 And drive the sliding seat 331 that is fixedly connected with the drive wheel drive belt 39 and is slidingly matched with the sliding guide rod 33, the front glue spraying nozzle fixing frame 3311 is driven by the sliding seat 331, and the front glue spraying nozzle fixing frame 3311 drives the front glue spraying nozzle to adjust Frame 341, because the front glue spray nozzle 34 of the PTC heating pipe is connected to the front glue spray nozzle adjustment frame 341, thus the front glue spray nozzle 34 (a pair) of the PTC heating pipe is in the state of motion (moving) to the two PTCs on the left side. The heating pipe 81 sprays the adhesive until the length direction of the upward side of the PTC heating pipe 81 uniformly obtains the adhesive. At this time, the front nozzle 34 of the PTC heating pipe moves from the rear side of the frame 1 to the frame 1 the front side. In the foregoing process, the PTC heating pipe back glue spraying nozzle 44 of the PTC heating pipe back glue spraying mechanism 4 completes spraying adhesive to the two PTC heating pipes 81 on the right side at the same time, because the aforementioned transition transmission shaft 36 is in a state of motion. In addition to driving the front drive wheel 37, it also drives the front motion wheel 45 of the structural system of the PTC heat pipe back side glue spraying mechanism 4, and the motion wheel drive belt 47 is driven by the front motion wheel 45, and is connected with it by the motion wheel drive belt 47. The sliding block 431 slidingly matched with the sliding guide rod 43 drives the back glue nozzle fixing frame 4311 by the sliding block 431, and the back glue spray nozzle fixing frame 4311 drives the back glue spray nozzle adjusting frame 441. 44 is connected to the back glue nozzle adjustment frame 441, so that the PTC heat pipes spray adhesive to the two PTC heat pipes 81 on the right side in the state of motion (moving) against the glue nozzle 44 (a pair).

The two PTC heating tubes 81 that have been sprayed by the glue nozzle 34 are turned over 180° by the PTC heating tube turning mechanism 7, so that the glue spraying nozzle 44 on the back side of the PTC heating tube is used for glue spraying, and the action state of turning the PTC heating tube 81 over 180° is determined by As shown in Figure 4, the specific process is: the lift cylinder 72 works, the lift seat 73 is pushed upward by the lift cylinder column 721, and the lift seat 73 drives the translation cylinder 74 and a pair of rotary clamping cylinders 75 to move upward. , so that the rotary head 751 of a pair of rotary clamping cylinder 75 and the clamping jaw 7511 correspond to the end of the PTC heating tube 81 (the front end of the position shown in FIG. 1 ). Then, the translation cylinder 74 works, and it drives the translation guide column 742, and the translation guide column 742 drives the rotary clamping cylinder seat 752 to displace in the direction of the PTC heating tube 81. Since a pair of rotary clamping cylinders 75 are installed on the rotary Clamp and place on the cylinder base 752, thus a pair of rotary clamp and release cylinders 75 are displaced in the direction of the PTC heating tube 81 along with the rotary clamping and releasing cylinder base 752, until the end of the PTC heating tube 81 enters the clamping claw 7511 and is placed in a pair of clamping jaws. Under the operation of the rotary clamping cylinder 75, it is in the state of being clamped by the jaws 7511. In this state, the pair of rotary clamping cylinders 75 work, and the rotary head 751 is rotated by 180°, thereby realizing the PTC heating tube 81 Flip 180°.
