Description

Automatic heating, pressurizing and leveling device for electric heating wire of protector

Technical Field

The invention belongs to the technical field of special facilities of an automatic production line of electronic and electric products, and particularly relates to an automatic heating, pressurizing and leveling device for an electric heating wire of a protector.

Background

The function of the motor protector of the refrigeration compressor is to provide effective protection for the temperature overload of the motor of the refrigeration compressor, and the structure can be referred to as an overload protector of a single-phase alternating current motor recommended by the patent grant publication No. CN100356652C, and the motor protector of the refrigeration compressor and the motor starter of the refrigeration compressor with the structure are reasonably combined to form a motor starter and protector of the refrigeration compressor, such as CN2606490Y (motor starter protector), CN2606491Y (integrated motor starter protector), CN102386815B (integrated motor starter protector with improved structure), CN100581043C (energy-saving integrated single-phase alternating current motor starter protector) and the like. A typical "energy-efficient integrated single-phase ac motor protection device" as provided by CN204425126U includes the structure of CN100356652C described above.

From a reading of the specifications not limited to those exemplified above, in particular CN100356652C and CN204425126U, in particular of the "energy-efficient single-phase ac motor start protector" recommended by the patent application publication No. CN104734569a, paragraphs 0039 to 0045 and a reading of fig. 4 in combination with this CN104734569a, it is known that: the motor protector for the refrigeration compressor mainly comprises a base, a fixed seat, a movable contact (also called a movable pin), a static contact (also called a static pin), an inserting piece (also called a pin), a bimetallic strip, an ejector rod and an electric heating wire, wherein the base is called a fixed seat and the fixed seat is called a base correspondingly. The movable contact, the stationary contact and the inserting sheet are all arranged by taking the base as a carrier (the base is called a fixed seat called CN100356652C herein), that is, the components are all arranged on the base.

As described in paragraph 0045 of the above description of CN104734569a, when the bimetal is exposed to radiant heat from the heating wire or the external environment, the bimetal is deformed, and the deformation is expressed as: the peripheral edge part is turned downwards, and the central part is arched upwards, so that the central part of the bimetallic strip is raised to push the push rod to displace upwards, the movable contact and the stationary contact of the two pins in the closed state are separated, and the circuit is disconnected, so that the compressor motor is protected.

The better the overall contact effect between the heating wire and the bimetallic strip of the structure system of the motor protector of the refrigeration compressor is, the better the deformation effect of the bimetallic strip is correspondingly, and the higher the reliability of the breaking circuit is. However, since the heating wire is manually received in the heating wire receiving chamber (also referred to as "receiving groove") provided at the side of the base facing the bimetal, and since the heating wire has a structure similar to that of a spring, the flatness of the heating wire mounted in the heating wire receiving chamber is different due to the experience, responsibility and emotion of the assembler, and the difference is as follows: it is difficult or even impossible to ensure the full contact of the heating wire with the bimetal. Yet another situation is: when the electric heating wire is initially assembled, even if the electric heating wire is not fully embedded in the electric heating wire accommodating cavity, the electric heating wire and the bimetallic strip basically can meet the expected contact state in the industry, but the integral contact effect between the electric heating wire and the bimetallic strip is more difficult to ensure due to repeated expansion and contraction changes along with the time. The problem of how to make the heating wire permanently and reliably contact the bimetal integrally has long plagued the industry and is desired to be solved. It is needless to say that if the heating wire is shaped to be flattened by adding a shaping station after the installation of the heating wire by a worker at the previous station, the aforementioned technical problem can be made up to a certain extent, but this measure wastes valuable labor resources, and if the shaping is performed manually by a worker without a rational automatic shaping device, the shaping efficiency and shaping effect are still not guaranteed. The technical solutions to be described below are created in this context.
