Description

Technical Field

[0001] This utility model belongs to the technical field of automated assembly facilities for motor protection components of refrigeration compressors, specifically relating to a bimetallic strip support ring installation device for an automated assembly machine for motor starter protectors. Background Technology

[0002] The aforementioned motor starter protector is a general term for a product that integrates the motor starter and motor protector into a single housing, i.e., the two are combined into one. The aforementioned bimetallic strip support ring is a component of the motor protector's structural system; its function can be found, but is not limited to, the Chinese patent CN204442206U (Energy-Saving Single-Phase AC Motor Starter Protector). Furthermore, regarding the specific structure and function of the motor starter protector, in addition to the aforementioned CN204442206U, see also CN100581043A (Energy-Saving Integrated Single-Phase AC Motor Starter Protector), and so on.

[0003] Although motor starter protectors are relatively small in size, they involve a relatively large number of components. Traditional manual assembly has at least two major technical problems: first, it is inefficient and requires a large workforce, wasting valuable labor resources and significantly increasing overall manufacturing costs; second, the quality of manual assembly is affected by variations in the assembler's experience, skill level, physical strength, sense of responsibility, and even mood, making it impossible to guarantee consistent assembly quality. Automated assembly can eliminate these technical problems. In automated assembly, after the housing supply device (the shape and structure of the housing can be varied, see the two patents mentioned above) supplies the housing to the housing support mold on a rhythmically rotating turntable, if the process involves installing the protector, then firstly, the bimetallic support ring needs to be installed into the base of the protector's structural system. The base is located within the protector cavity of the aforementioned housing. Regarding the protector cavity, such as the aforementioned CN204442206U referred to as the "single-phase AC motor protector cavity," to form a complete cycle chain where the bimetallic strip support ring, input from the vibrator via the track (i.e., via the bimetallic strip support ring), is sequentially extracted, moved (transferred), released, and returned for further extraction, a reliable and stable automated device is essential. In other words, the aforementioned bimetallic strip support ring installation device needs to ensure the required cycle time of the process, because after the bimetallic strip support ring is installed, the next station will install the bimetallic strip into the aforementioned base for support by the bimetallic strip support ring. Furthermore, it must avoid interference with adjacent station devices and maximize operational stability and structural simplicity. Because the bimetallic strip support ring has relatively thin washers, the conventional approach of using grippers for handling often proves ineffective. Utility Model Content

The sliding plate 50125 of the lifting cylinder of the bearing ring quantity detection sensor 5012 is located on the side of the lifting cylinder of the bearing ring quantity detection sensor 5012 facing the aforementioned rotary table 1. On the side of the sliding plate 50125... A signal acquisition trigger block 50126 is fixed at the position between the upper and lower displacement limit position signal acquisition blocks 50121 and 50122 on the sliding plate of the lifting cylinder corresponding to the support ring quantity detection sensor.

The support ring quantity detection sensor 5014 is fixed on the support ring quantity detection sensor mounting platform 50131 and corresponds to the upper part of the aforementioned housing bearing mold 11.

[0027] Please pay attention. 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 support ring camera detection device 502 is responsible for obtaining information by camera whether the bimetallic support ring 40 is missing inside the housing 30 to be assembled. When the support ring camera 5023 (i.e. the probe) does not capture the bimetallic support ring 40, it feeds back information to the electrical controller, which then issues a stop command to the aforementioned rotary table drive mechanism. The online operator then handles the situation by manually inserting a bimetallic support ring 40, for example.

[0031] Applicant combined Figure 1 and Figure 2The working principle of this utility model is described as follows: Under the command of the electrical controller, the bimetallic support ring suction and release drive motor 31 operates, which drives the bimetallic support ring suction and transfer release device lateral displacement fixing plate drive disk 312, which is fixed to it by a set of screws, to rotate together with the drive disk swing arm 3121. The drive disk swing arm roller shaft 31211 on the drive disk swing arm 3121 drives the drive disk swing arm roller 31212, which forces the suction nozzle lateral displacement connecting plate 33 to translate to the right. During the rightward translation, since a sliding pair relationship is formed between the suction nozzle lateral displacement connecting plate slider 333 and the lateral sliding rail 3241, the suction nozzle lateral displacement connecting plate 33 exhibits smooth translation. Simultaneously, the two pairs of left-right moving guide wheels 331 of the lateral displacement connecting plate located on the upper rear side of the nozzle lateral displacement connecting plate 33, and the edge of the drive disk 312 of the lateral displacement fixing plate of the bimetallic support ring suction transfer release device, alternately form rolling pairs in a tangential manner. Here, "alternating" means that when the right pair of the two pairs of left-right moving guide wheels 331 forms a rolling pair with the edge of the disk, the left pair disengages from forming a rolling pair with the edge of the disk, and vice versa. During the aforementioned process, since the drive disk swing arm roller 31212 engages with the drive disk swing arm roller mating groove 3411, it drives the nozzle up-and-down lifting drive rod 34 to move upward. Furthermore, since the lower end of the nozzle up-and-down lifting drive rod 34 is fixed to the nozzle lateral displacement guide rail 35, when it moves upward, it drives the nozzle lateral displacement guide rail 35, along with the bimetallic support ring suction transfer release device fixing plate 351, and the first and second extraction transfer release components 361 and 362 of the support ring, to move upward. When the aforementioned suction nozzle lateral displacement connecting plate 33 moves to the right to the point where the right end of the aforementioned lateral displacement fixed plate left and right displacement signal acquisition device excitation rod 342 is able to be acquired by the bimetallic support ring suction transfer release device lateral displacement fixed plate right displacement signal acquisition device 323 (using a photoelectric sensor), the bimetallic support ring 40, which is still in the state of being sucked by the suction pipes 3616 of the first and second extraction transfer release components 361 and 362 of the support ring, is respectively above the support ring transition platform 39 and the shell bearing mold 11 on the rotary table 1. At the same time, the aforementioned bimetallic support ring suction transfer release device lateral displacement fixed plate right displacement signal acquisition device 323 feeds the signal back to the electrical controller, and the electrical controller makes the aforementioned suction pipes 3616 of the first and second extraction transfer release components 361 and 362 of the support ring become positive pressure (described below), and releases the previously sucked bimetallic support ring 40 into the support ring transition platform 39 and the shell bearing mold 11 at the same time.Next, the electrical controller issues a command to reverse the bimetallic support ring suction and release drive motor 31, repeating the reverse operation process until the left displacement signal acquisition device 322 of the lateral displacement fixed plate acquires the position signal of the left end of the excitation rod 342 of the lateral displacement fixed plate. During this process, the two suction pipes 3616 pick up the next (new) bimetallic support ring 40 from the bimetallic input track 10 equipped with the bimetallic input track vibrator 101 towards one end of the suction pipe 3616 and the support ring transition platform 39. After a delay set by the PLC, such as 4 or 5 seconds, the electrical controller issues a command to the bimetallic support ring suction and release drive motor 31 to work in reverse.

[0032] As described above regarding the operation of the bimetallic strip support ring suction and release mechanism 3, when the two suction pipes 3616 descend and reach the top position corresponding to the bimetallic strip input track 10 and the support ring transition platform 39, one bimetallic strip support ring 40 is simultaneously sucked up by the two suction pipes 3616. After sucking up the bimetallic strip support ring 40, the bimetallic strip support ring suction, transfer, and release device 36 ascends and simultaneously moves to the right. When it reaches the positions corresponding to the support ring transition platform 39 and the housing support mold 11 on the rotary table 1, it descends and simultaneously releases the previously sucked bimetallic strip support ring 40 into the support ring transition platform 39 and the housing support mold 11, respectively. Then it ascends and moves to the left, repeating this process. The time taken by the aforementioned bimetallic strip support ring pick-up, transfer and release device 36 from picking up the bimetallic strip support ring 40 to transferring and releasing the bimetallic strip support ring 40 is the working time of one station, such as 4 seconds or 5 seconds set by the PLC (Programmable Logic Controller), which is the time interval between the previous response and the next response of the rotary table drive mechanism that drives the rotary table 1 to rotate.

[0033] Continue to combine Figure 1 and Figure 2The applicant further explains: Since the aforementioned bimetallic strip support ring suction transfer release device 36 includes a support ring first extraction transfer release component 361 and a support ring second extraction transfer release component 362, the aforementioned support ring first extraction transfer release component 361 reciprocates between the top of the aforementioned bimetallic strip support ring input track 10 facing the aforementioned rotary table 1 (more precisely, facing the suction pipe 3616) and the top of the aforementioned support ring transition platform 39, while the aforementioned support ring second extraction transfer release component 362 reciprocates between the top of the support ring transition platform 39 and the top of the aforementioned housing support mold 11 disposed on the aforementioned rotary table 1. When the nozzle lateral displacement connecting plate 33, together with the nozzle up-and-down lifting drive rod 34 and the nozzle lateral displacement guide rail 35 mounted on it, moves to the left so that the first extraction and transfer release component 361 of the bimetallic support ring suction and transfer release device 36 is positioned above the end of the bimetallic support ring input track 10 facing the rotary table 20 and the second extraction and transfer release component 362 is positioned above the support ring transition platform 39, as the nozzle lateral displacement guide rail 35 and the bimetallic support ring suction and transfer release device fixing plate 351 move downward, the opening of the suction pipe air inlet 36165 of the suction pipe 3616 of the first extraction and transfer release component 361 of the support ring is close to the bimetallic support ring 40. At the same time, the suction pipe air inlet 36165 of the suction conduit of the second extraction and transfer release component 362 of the support ring (since it is equivalent to the suction pipe 3616, the applicant used the concept of two above) is also close to the bimetallic support ring 40. Taking the first extraction, transfer and release assembly 361 of the support ring as an example, when the pipeline connected to the negative pressure generating device, such as a vacuum pump or other similar device, draws air into the air inlet 36163 (also known as vacuuming), the air inlet 36165 of the air inlet pipe draws air (intakes air) and holds the bimetallic support ring 40. Under the reverse operation of the bimetallic support ring suction and release drive motor 31, the suction nozzle lateral displacement guide rail 35 moves upward and to the right, so that the bimetallic support ring 40 held by the suction pipe 3616 is transferred from the end of the bimetallic support ring input track 10 facing the rotary table 1 to the top of the corresponding support ring transition platform 39. Then the suction stops, and the suction pipe 3616 changes from negative pressure to positive pressure, thereby releasing the bimetallic support ring 40 onto the support ring transition platform 39. The bimetallic support ring 40 previously located on the support ring transition platform 39 is then picked up by the support ring second extraction and transfer release component 362 and transferred and released into the housing 30 to be assembled on the housing support mold 11. By repeating the above process, the bimetallic support ring 40 input by the bimetallic support ring input track 10 can be introduced into the housing 30 to be assembled in a relay manner according to the rhythm set by the PLC.

[0034] Depend on Figure 1As can be seen from the diagram, the bimetallic strip support ring extraction and release mechanism 3 of this invention does not interfere with the bimetallic strip support ring input track 10, nor with the support ring transition platform 39 or the bimetallic strip support ring extreme case detection mechanism 50. After the bimetallic strip support ring 40 is automatically installed, the rotary table 1 rotates to the position of the aforementioned bimetallic strip support ring extreme case detection mechanism 50. After the rotary table 1 rotates through one position, the bimetallic strip extraction and release mechanism automatically assembles the bimetallic strip.

[0035] In summary, the technical solution provided by this utility model makes up for the shortcomings of the prior art, successfully completes the utility model task, and faithfully realizes the technical effects described by the applicant in the above technical effect column.
