Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of automatic assembly facilities for refrigeration compressor motor protection components, in particular to a bimetallic strip supporting ring mounting device of an automatic motor starting protector assembly machine. BACKGROUND

[0002] The aforementioned motor starting protector is a general term for products in which a motor starter and a motor protector are combined in the same housing, i.e., a combination of the two. The aforementioned bimetallic strip supporting ring is a component of the structural system of the motor protector, and its function can be seen in, but not limited to, Chinese Patent CN204442206U (Energy-saving single-phase alternating current motor starting protector). In addition, for the specific structure and function of the motor starting protector, in addition to the aforementioned CN204442206U, CN100581043A (Energy-saving integrated single-phase alternating current motor starting protector) can also be referred to.

[0003] Although the motor starting protector is relatively small in size, it involves relatively many components. In the past, manual assembly has at least the following two major technical problems: first, the assembly efficiency is low, and the labor input is large, which not only wastes valuable labor resources, but also significantly increases the overall manufacturing cost; second, the quality of the assembly is affected by the experience, proficiency, physical ability, responsibility, and even mood of the assembly personnel, so the consistency of the assembly quality cannot be guaranteed. Automation assembly can eliminate the aforementioned technical problems. In the automation assembly link, when the shell supply device (the shape and structure of the shell can be seen in the above-mentioned two patents) supplies the shell to the shell carrying mode on the rotating disc rotating rhythmically, if the process involves the installation of the protector, the bimetallic strip supporting ring needs to be installed into the base of the structural system of the protector first. The base is located in the protector cavity of the aforementioned shell. As for the protector cavity, for example, the aforementioned CN204442206U refers to "single-phase alternating current motor protector cavity", if the bimetallic strip supporting ring input by the vibrator through the track, i.e., through the bimetallic strip supporting ring input track, is to be sequentially extracted, moved, released, and returned to be extracted again to form a complete circulation chain, it must be guaranteed by an automatic device with reliable and stable action. That is, the aforementioned bimetallic strip supporting ring mounting device needs to guarantee the required rhythm of the process, because after the installation of the bimetallic strip supporting ring is completed, the next station will load the bimetallic strip into the aforementioned base in order to be supported by the bimetallic strip supporting ring. And it also needs to avoid the interference of the bimetallic strip supporting ring mounting device to the device at the adjacent station and to embody the stability of the action and the simplicity of the structure as much as possible. Because the bimetallic strip supporting ring has the feature of a relatively thin washer, the idea of being clamped by a jaw according to the conventional method often fails. SUMMARY

[0004] The task of the present application is to provide a bimetallic strip supporting ring mounting device of motor protection device automatic assembly machine which is helpful to meet the action reliability requirement of complete cycle chain, to ensure the required process beat, to avoid interference effect on devices at adjacent stations, to ensure the harmony of automatic assembly, to benefit the simplicity of structure, to facilitate manufacturing, use and maintenance, to facilitate the protection of extraction and release effect of bimetallic strip supporting ring, and to avoid the influence of automatic installation beat of the whole machine due to extraction or release failure.

A signal collector trigger bump 50126 is fixed on the side surface of the sliding plate 50125 and at a position corresponding to the support ring quantity detection sensor lifting cylinder sliding plate upper and lower displacement limit position signal collector fixing blocks 50121 and 50122. The lower end of the support ring quantity detection sensor fixing seat 5013 is fixed on the side of the sliding plate 50125 facing the rotary disc 1, and the upper end constitutes a support ring quantity detection sensor fixing platform 50131. The support ring quantity detection sensor 5014 is fixed on the support ring quantity detection sensor fixing platform 50131 and corresponds to the upper part of the aforementioned shell bearing mode 11.

[0027] Please see Figure 1The aforementioned support ring camera detection device 502 includes a support ring camera mount fixing column 5021, a support ring camera mount 5022, and a support ring camera 5023. The support ring camera mount fixing column 5021 is located to the right of the aforementioned support ring quantity detection sensor lifting cylinder fixing frame 5011, and the lower end of the support ring camera mount fixing column 5021 is fixed to the aforementioned worktable 2, while the upper end extends upward in a longitudinal state. The support ring camera mount 5022 is fixed to the upper end of the support ring camera mount fixing column 5021, and the support ring camera 5023 is fixed on the support ring camera mount 5022 and corresponds to the upper part of the aforementioned housing support mold 11.

[0028] because Figure 1 The concept of the bimetallic strip support ring 40 and its specific function in the refrigeration compressor motor protector are prior art and can be found in published Chinese patent documents, such as the "Energy-Saving Single-Phase AC Motor Starter Protector" recommended in CN204442206U. Therefore, the applicant will not elaborate further. The bimetallic strip 60, which will be mentioned below, is the same example.

[0029] To obtain information on whether the bimetallic support ring extraction and release mechanism 3 has introduced the bimetallic support ring 40 into the housing 30 to be assembled according to process requirements, i.e., to obtain information on whether there are two or more overlapping bimetallic support rings 40 or an undesirable extreme situation of missing rings, the aforementioned support ring quantity detection device 501 measures the quantity. Specifically, when there are two or more double-overlapping bimetallic support rings 40 in the housing 30 to be assembled, the support ring quantity detection sensor 5014 detects this and feeds the signal back to the electrical controller. The electrical controller then issues a stop command to the rotary table drive mechanism (set on the worktable 2) used to rotate the rotary table 1, and the online operator removes the excess bimetallic support rings 40. Figure 3 As can be seen from the diagram, the degree of vertical displacement of the aforementioned support ring quantity detection sensor 5014 is determined by the sliding plate 50125 of the actuating cylinder, and the degree of vertical displacement of the actuating cylinder sliding plate 50125 is determined by the vertical displacement stroke of its signal acquisition trigger block 50126. Specifically, it is adjusted within the range of the upper and lower displacement limit positions of the upper and lower displacement limit positions of the support ring quantity detection sensor lifting actuating cylinder sliding plate signal acquisition fixing blocks 50121 and 50122. Once the adjustment is in place to accurately measure a bimetallic support ring 40 without feeding back an abnormal signal to the electrical controller, the support ring quantity detection sensor lifting actuating cylinder 5012 keeps the actuating cylinder sliding plate 50125 at this level, and correspondingly, the support ring quantity detection sensor 5014 also stays at this level.

[0030] The aforementioned supporting ring camera detection device 502 plays a role of acquiring by camera whether the bimetallic strip supporting ring 40 is missing in the to-be-assembled shell 30. When the supporting ring camera 5023 (i.e. the probe) does not capture the bimetallic strip supporting ring 40, the information is fed back to the electrical controller, the electrical controller issues a stop working instruction to the aforementioned turntable driving mechanism, and the on-duty operator handles, for example, manually supplements a bimetallic strip supporting ring 40.

[0031] The applicant combines Figure 1 and Figure 2The working principle of the present application is described as follows. Under the instruction of the electrical controller, the bimetallic strip supporting ring drives the motor 31 to work, which drives the bimetallic strip supporting ring to move horizontally through a set of screws fixed to the bimetallic strip supporting ring, and drives the horizontal displacement fixed plate 312 of the bimetallic strip supporting ring to rotate together with the swing arm 3121 of the driving disc, which drives the driving disc swing arm roller 31211 on the swing arm 3121 to rotate, and drives the driving disc swing arm roller 31212 to move to the right. During the movement to the right, the horizontal displacement connecting plate 33 is stable due to the sliding pair relationship between the horizontal displacement connecting plate slider 333 and the horizontal sliding rail 3241. Meanwhile, the two pairs of horizontal displacement connecting plate left and right moving guide wheels 331 on the upper end of the rear side of the horizontal displacement connecting plate 33 and the disc edge of the horizontal displacement fixed plate driving disc 312 of the bimetallic strip supporting ring form a rolling pair alternately, which means that when the right pair of the two pairs of horizontal displacement connecting plate left and right moving guide wheels 331 forms a rolling pair with the disc edge, the left pair exits the rolling pair with the disc edge, and vice versa. During the above process, the upward movement of the nozzle up and down lifting driving rod 34 is driven by the cooperation between the driving disc swing arm roller 31212 and the driving disc swing arm roller matching groove 3411. Since the lower end of the nozzle up and down lifting driving rod 34 is fixed to the nozzle horizontal displacement guide rail 35, the nozzle horizontal displacement guide rail 35 moves upward together with the bimetallic strip supporting ring, the horizontal displacement fixed plate 351, the first and second extraction and transfer release assemblies 361, 362. When the horizontal displacement connecting plate 33 moves to the right to the extent that the right end of the horizontal displacement fixed plate left and right displacement signal collector 342 is collected by the bimetallic strip supporting ring horizontal displacement fixed plate right displacement signal collector 323 (using an optical sensor), the bimetallic strip supporting ring 40, which is still in the state of being sucked by the suction pipe 3616 of the first and second extraction and transfer release assemblies 361, 362, corresponds to the upper side of the shell bearing mode 11 on the bimetallic strip supporting ring transition platform 39 and the rotary disc 1. At the same time, the signal is fed back to the electrical controller by the bimetallic strip supporting ring horizontal displacement fixed plate right displacement signal collector 323, and the electrical controller changes the positive pressure of the suction pipe 3616 of the first and second extraction and transfer release assemblies 361, 362 to release the bimetallic strip supporting ring 40 into the bimetallic strip supporting ring transition platform 39 and the shell bearing mode 11.Then the electrical controller sends a command to the bimetallic strip support ring suction release drive motor 31 to reverse, according to the opposite action process described above until the bimetallic strip support ring suction transfer release device horizontal displacement fixed plate left displacement signal collector 322 collects the position signal of the left end of the horizontal displacement fixed plate left and right displacement signal collector actuating rod 342. In this process, the two suction pipes 3616 from the bimetallic strip input track 10 equipped with the bimetallic strip input track vibrator 101 towards the end of the suction pipe 3616 and the support ring transition platform 39 suck the next (new) bimetallic strip support ring 40, after a delay of a time set by the PLC such as 4 seconds or 5 seconds, the electrical controller sends a command to the bimetallic strip support ring suction release drive motor 31 to reverse.

[0032] From the above description of the working process of the bimetallic strip support ring suction release mechanism 3, it can be seen that the two suction pipes 3616 descend and when they are above the top of the bimetallic strip input track 10 and the support ring transition platform 39, they simultaneously suck a bimetallic strip support ring 40. After sucking the bimetallic strip support ring 40, the bimetallic strip support ring suction transfer release device 36 ascends and simultaneously translates to the right. When it moves to the positions corresponding to the support ring transition platform 39 and the shell carrying mode 11 on the rotary disc 1 respectively, it descends and simultaneously releases the previously sucked bimetallic strip support ring 40 into the support ring transition platform 39 and the shell carrying mode 11 respectively, then ascends and translates to the left, and so on. The time taken by the bimetallic strip support ring suction transfer release device 36 to suck the bimetallic strip support ring 40, transfer and release the bimetallic strip support ring 40 is the working time of one station, for example 4 seconds or 5 seconds set by the PLC (programmable controller), that is, the time interval between the previous response and the next response of the rotary disc drive mechanism that drives the rotary disc 1 to rotate.

[0033] Continue to combine Figure 1 And Figure 2, the applicant makes further explanation: since the aforementioned bimetallic strip support ring suction transfer release device 36 comprises a support ring first extraction transfer release assembly 361 and a support ring second extraction transfer release assembly 362, the aforementioned support ring first extraction transfer release assembly 361 reciprocates between the upper side of the aforementioned support ring input track 10 towards the aforementioned rotary disc 1 (more precisely, towards the suction pipe 3616) and the upper side of the aforementioned support ring transition platform 39, while the aforementioned support ring second extraction transfer release assembly 362 reciprocates between the upper side of the support ring transition platform 39 and the upper side of the aforementioned shell carrying mode 11 arranged on the aforementioned rotary disc 1. When the suction nozzle transverse displacement connecting plate 33, together with the suction nozzle up-down lifting driving rod 34 arranged thereon and the suction nozzle transverse displacement guide rail 35, are displaced to the left to the position where the support ring first extraction transfer release assembly 361 of the bimetallic strip support ring suction transfer release device 36 corresponds to the upper side of the end of the bimetallic strip support ring input track 10 towards the rotary disc 20 and the support ring second extraction transfer release assembly 362 corresponds to the upper side of the support ring transition platform 39, as the suction nozzle transverse displacement guide rail 35, together with the downward movement of the bimetallic strip support ring suction transfer release device fixing plate 351, the suction pipe air inlet hole 36165 of the suction pipe 3616 of the support ring first extraction transfer release assembly 361 is close to the bimetallic strip support ring 40, while the suction pipe air inlet hole (equivalent to the suction pipe air inlet hole 36165) of the suction pipe (equivalent to the suction pipe 3616) of the support ring second extraction transfer release assembly 362 is also close to the bimetallic strip support ring 40. Taking the support ring first extraction transfer release assembly 361 as an example, under the suction (also known as vacuumization) of the suction port 36163 by the pipeline connected to the negative pressure generating device such as a vacuum pump or other similar device, the suction pipe air inlet hole 36165 sucks (intakes) the bimetallic strip support ring 40. Under the reverse operation of the bimetallic strip support ring suction release driving motor 31, the suction nozzle transverse displacement guide rail 35 is displaced upwards and to the right, so that the bimetallic strip support ring 40 sucked by the suction pipe 3616 is transferred from the previous position on the end of the bimetallic strip support ring input track 10 towards the rotary disc 1 to the upper side of the support ring transition platform 39, then stops suction, the suction pipe 3616 changes from the previous negative pressure to positive pressure, thereby releasing the bimetallic strip support ring 40 onto the support ring transition platform 39, and the bimetallic strip support ring 40 previously located on the support ring transition platform 39 is sucked and transferred by the support ring second extraction transfer release assembly 362 into the shell to be assembled 30 on the shell carrying mode 11, and the aforementioned process is repeated to introduce the bimetallic strip support ring 40 input from the bimetallic strip support ring input track 10 into the shell to be assembled 30 in a relay manner at the rhythm set by the PLC.

[0034] By Figure 1As can be seen from the schematic, the bimetallic strip supporting ring suction release mechanism 3 of the present application neither interferes with the bimetallic strip supporting ring input track 10, nor interferes with the supporting ring transition platform 39 and the bimetallic strip supporting ring extreme situation detection mechanism 50. After the bimetallic strip supporting ring 40 is automatically installed by the present application, the rotary disc 1 is rotated to the position of the aforementioned bimetallic strip supporting ring extreme situation detection mechanism 50, and then the rotary disc 1 is rotated by one position, and the bimetallic strip is automatically assembled by the bimetallic strip extraction release mechanism.

[0035] In summary, the technical solutions provided by the present application make up for the shortcomings in the prior art, successfully complete the invention task, and faithfully fulfill the technical effects described in the technical effect column above.
