Description

Automatic welding machine for electric heating wire of motor protector
Technical Field
The invention belongs to the technical field of automatic welding machinery of electrical components of a refrigeration compressor, and particularly relates to an automatic welding machine for an electric heating wire of a motor protector.
Background
The motor protector mentioned above is a motor starting protector, and the motor starting protector is a refrigeration compressor motor starting protector, and the refrigeration compressor motor starting protector is also called a refrigeration compressor single-phase alternating current motor overload protector, and has the functions of: effective protection is provided for the over-temperature and overload of the temperature of the single-phase alternating current motor, and technical information related to the motor protector, such as CN2218263Y (self-protection type refrigeration compressor thermal protector), CN2287339Y (refrigeration compressor motor protector), CN1207743C (thermal protector), CN2341305Y (current-temperature composite type motor protector), CN100356652C (overload protector of the single-phase alternating current motor), and the like, can be seen in the published chinese patent documents. It is known from a reading of the patent literature, not limited to the above, in particular from a reading of CN100356652C, combined with the common general knowledge: in the structural system of the motor protector, a heating wire supported on a bimetallic strip in a use state is provided, two ends of the heating wire are respectively provided with a first leading-out pin of the heating wire and a second leading-out pin of the heating wire, the first leading-out pin of the heating wire is welded with a movable contact spring piece of the structural system of the motor starting protector, and the second leading-out pin of the heating wire is welded with a protector pin of the structural system of the motor starting protector (for details, refer to CN104734570A < power consumption free energy saving type single-phase alternating current motor starting protector >). Since the mechanism of action of motor protectors, including their heating wires, is well known and can likewise be understood from a reading of the aforementioned patent documents, no further details are given to the applicant.
In the prior art, the first and second leading-out pins of the heating wire (also called "two end ends of the heating wire", the same applies hereinafter) are respectively welded to the movable contact spring piece and the protector pin by a worker in a manual mode, which is a working mode that is used up to now and is like "slow work" in the industry, and then is considered as a unique working mode that cannot be replaced by other methods, but the following technical problems exist objectively: first, since the components constituting the motor start protector, such as the heating wire, the protector pin (also called as the protector electrical pin, the same below), the moving contact spring piece, the stationary contact spring piece, the base, the fixed base, and the bimetallic strip, tend to be processed by mechanical automation, and since the efficiency of processing the aforementioned components by mechanical automation is relatively high, and since the speed of welding the first and second lead-out pins of the heating wire with the aforementioned moving contact spring piece and the protector pin, respectively, in a manual manner is very slow, in order to match the automatic high-efficiency processing speed of the aforementioned components, a considerable number of welders must be provided to meet the requirement of the industrial production speed, thereby consuming a large amount of labor resources on one hand, and causing high labor wage cost to be paid by manufacturers of the motor start protectors on the other hand, and finally, the motor protector is not beneficial to the cheapness of the motor protector product; secondly, because the manual welding is adopted, the volume of the added components is relatively small, and particularly, the leading-out feet of the electric heating wires at the two ends of the electric heating wires are fine, the welding worker is always in a highly tense state in the working process, and the labor intensity is high. In addition, since the heating wire is disposed on the bimetallic strip in a substantially C-shaped manner in a use state, the heating wire is also referred to as a "coil"; thirdly, because of manual welding, the welding quality is different according to different experiences, responsibilities, emotions, physical conditions and psychological conditions of workers, so that the inspection workload in the subsequent process is increased, the detection rate of unqualified welding products caused by insufficient welding, desoldering and the like is relatively high, on one hand, the resource waste is caused, and on the other hand, the quality is uneven. Based on the technical problems not limited to the foregoing, it is necessary to make up for the problems by other good processing methods, and for this reason, the applicant has conducted extensive searches on the intermediate and external patent and non-patent documents, but has no reference to any beneficial teachings, and the technical solutions to be described below are made under such circumstances.

Detailed Description
In order to clearly understand the technical spirit and the advantages of the present invention, the applicant below describes in detail by way of example, but the description of the example is not intended to limit the technical scope of the present invention, and any equivalent changes made according to the present inventive concept, which are merely in form and not in material, should be considered as the technical scope of the present invention.
In the following description, all the concepts related to the directions or orientations of up, down, left, right, front and rear are based on the position state of fig. 1, and thus, it should not be understood as a particular limitation to the technical solution provided by the present invention.

As a more perfect design, a protector removing mechanism 8 capable of automatically removing the protector 10 (shown in fig. 10) that has completed welding from the temporary protector arranging mechanism 4 may be added to the structural system of the automatic electric heating wire welding machine of the above-described motor protector and at a position located at the rear of the second leading pin welding mechanism 7 of the electric heating wire, and the addition of the protector removing mechanism 8 may further reduce the working strength of the operator (worker), because the operator only needs to insert the protector 10 to be welded into the temporary protector arranging mechanism 4, and does not need to consider to remove the protector 10 that has completed welding from the temporary protector arranging mechanism 4, thereby further improving the degree of automation of the invention. The following description is made in terms of the overall structure of the present invention to which the aforementioned protector removing mechanism 8 is added.
As can be seen from the above description and the schematic diagram of fig. 1, the present invention actually has five stations, the first station is a protector receiving station, which is a protector feeding station, i.e., a first station, in which a protector 10 (i.e., "motor start protector", the same applies hereinafter) having a structure shown in fig. 10 to be welded is inserted, embedded or fed in a relay manner to a group of temporary protector mounting mechanisms 4 by an operator, and the remaining four stations are, in sequence, a second station, i.e., a second station, where the protector loss detection mechanism 5 is located, a third station, i.e., a station, where the first heating wire lead-out pin welding mechanism 6 is located, a fourth station, i.e., a station, where the second heating wire lead-out pin welding mechanism 7 is located, and a fifth station, i.e., a station, where the additional protector removing mechanism 8 is located. The aforementioned sequence of these stations is arranged on the table 1 in a clockwise state around the periphery of the turn disc 3.

According to the common knowledge, before fixing, the reduction gearbox power output shaft connecting hole 31 of the rotary disk 3 is sleeved on the reduction gearbox power output shaft 222, and then the rotary disk is fixed by the rotary disk fixing screw 321.
In the present embodiment, the driving pulley 23 and the driven pulley 24 are both pulleys, and the corresponding transmission belt 25 is a transmission belt, however, if a sprocket is used instead of the pulley, and a chain is used instead of the belt, the equivalent change should be considered.
