Description

Technical Field

[0001] This utility model relates to the field of heater processing technology, specifically to an assembly device for processing PTC heaters. Background Technology

[0002] In the production and processing of PTC heaters, the assembly process is a key link to ensure product performance. The assembly process requires applying adhesive to the heater wires. Applying adhesive to the heater wires refers to the process of applying adhesive to the connection between the PTC heating element wires (such as power cords, electrode leads, etc.) and the heating body through processes such as coating, potting, or dispensing, in order to achieve insulation protection, fix the wires, prevent moisture and corrosion, and enhance mechanical strength.

[0003] When applying glue to the heater wire using a glue applicator, the applicator is in prolonged contact with the glue, and some glue residue remains at the bottom of the applicator when the machine stops. This makes the applicator prone to clogging and clumping, requiring frequent replacement of the applicator. Most applicators are rigidly connected to the hose with bolts, requiring operators to use wrenches, screwdrivers, or other tools to remove the bolts or unfasten the clips when replacing the applicator. This process is time-consuming, and frequent disassembly and assembly can lead to wear on the mounting holes, stripped threads, and reduced connection accuracy. To address these issues, the inventor proposes an assembly device for processing PTC heaters. Utility Model Content

A U-shaped frame 31 is rotatably connected between the inner walls of the two sides of the plate 3 and the U-shaped plate 3. A shaft 32 is symmetrically fixedly connected near the center of the side end of the U-shaped frame 31. A limiting plate 33 is slidably connected between the outer rings of the two shafts 32. A spring 34 is fixedly connected to the side end of the limiting plate 33 and sleeved on the outer ring of the shaft 32. The other end of the spring 34 is fixedly connected to the U-shaped frame 31. A motor is provided on the side end of the U-shaped plate 3 to drive the U-shaped frame 31 to rotate. A limiting groove is symmetrically opened at the opposite ends of the limiting plate 33 and the U-shaped frame 31 to limit the heater and facilitate the application of glue to its wires. The electrical components in this application are electrically connected to their compatible power supply through wires. A suitable controller should be selected according to the actual situation to meet the control requirements. The detailed connection methods are known in the art.

[0022] A glue storage tank 23 is fixedly connected to the center of the top of the mounting plate 22.

[0023] By adopting the above technical solution, the glue storage tank 23 has an inlet at the top and a cap is provided at the inlet to prevent dust from entering.

[0024] A peristaltic pump 24 is provided at the bottom of the glue storage tank 23, and the other end of the peristaltic pump 24 is fixedly connected to the glue tube 25.

[0025] By adopting the above technical solution, the working peristaltic pump 24 is started, so that the glue inside the glue storage tank 23 is delivered to the glue tube 25.

[0026] The other end of the insertion rod 46 is fixedly connected to the mounting plate 47. A ball is provided at the center of the side end of the mounting plate 47. A spring 48 is fixedly connected to the side end of the mounting plate 47 and sleeved on the outer ring of the insertion rod 46. The other end of the spring 48 is fixedly connected to the outer ring of the sleeve shaft 4.

[0027] By adopting the above technical solution, the mounting plate 47 will squeeze the spring 48 under the action of the ball, so that it can achieve the effect of reciprocating reset.

[0028] The outer ring of the sleeve shaft 4 is provided with an external thread 42 near the bottom. The outer ring of the sleeve shaft 4 is rotatably connected to the external thread 42 and a lifting ring 43 is rotatably connected to the top of the lifting ring 43. A circular shell 44 is rotatably connected to the top of the lifting ring 43.

[0029] By adopting the above technical solution, an external thread 42 is provided on the outer ring of the sleeve shaft 4 to facilitate the lifting and lowering of the lifting ring 43. The lifting ring 43 is provided with a matching internal thread. The lifting ring 43 is rotatably connected to the annular shell 44 to facilitate the lifting and lowering of the annular shell 44. The rotation of the lifting ring 43 will not affect the normal operation of the annular shell 44. The two are connected by a guide groove and a slider, which are not specifically described in the figure.

[0030] An inclined platform 45 is fixedly connected to the inner wall of the annular shell 44 near the mounting plate 47, and the ball bearings cooperate with the inclined platform 45.

[0031] The inclined platform 45 is set up by adopting the above technical solution in order to cooperate with the ball bearing to achieve the effect of compressing the spring 48.

[0032] The bottom end of the mounting plate 22 is fixedly connected to a circular shell 2 5, and the circular shell 2 5 is fitted onto the outer ring of the sleeve shaft 4.

[0033] By adopting the above technical solution, a circular shell 5 is set at the bottom of the mounting plate 22 to facilitate the installation of the heating wire 51.

[0034] Several heating wires 51 are fixedly connected to the inner wall of the annular shell 2 5.

[0035] By adopting the above technical solution, a heating wire 51 is provided on the inner wall of the annular shell 25 to heat the glue tube 25 and facilitate the uniform flow of glue in the glue tube 25.

[0036] Working principle: When using this device, firstly, glue is added into the glue storage tank 23, then the limiting plate 33 is stretched to one side, and then multiple heaters that need to be glued to the wires are placed on the side of the U-shaped frame 31. Then, the tension on the limiting plate 33 is released. At this time, under the action of the spring 34, the limiting plate 33 can move towards the heater under the action of the two insert shafts 32, thus completing the limiting work of the heater.

[0037] Then, the peristaltic pump 24 is started, which delivers the glue inside the glue storage tank 23 to the glue tube 25. (At this time, multiple heating wires 51 need to be activated so that the glue can flow evenly in the glue tube 25.) Finally, it is delivered to the position where glue needs to be applied by the heater through the glue dispensing head 41 connected below. (Precise glue application is achieved by running the drive slide 1 21 and drive slide 2 26.) If the glue dispensing head 41 is blocked due to residual glue and needs to be replaced, the lifting ring 43 is rotated to drive the ring shell 1 44 to descend. Then, under the action of the mounting plate 47 and the spring 2 48, the insertion rod 46 is moved out of the slot 49, thereby releasing the limit on the glue dispensing head 41 and facilitating the quick replacement of the glue dispensing head 41.

[0038] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
