Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of automatic assembly of electrical components, in particular to a shell feeding device of an automatic assembly machine for refrigeration compressor motor starting protectors. BACKGROUND

[0002] Motor starting protector is a product that combines motor starter and motor protector in the same shell. There are many technical information related to refrigeration compressor motor starting protectors in the published Chinese patent documents. Its function can be fully understood by reading the following patent documents such as CN100581043A (Energy-saving integrated single-phase AC motor starting protector) and CN204442206U (Energy-saving single-phase AC motor starting protector) and the like.

[0003] As known in the industry, if manual assembly is used for refrigeration compressor motor starting protectors, the following technical problems will arise: first, due to the relatively low assembly efficiency, it is difficult to adapt to the speed of automatic assembly of other components such as the structure system of the protector, such as the static contact piece, the dynamic contact piece, the dynamic insertion piece, etc. Unless enough workers are invested, excessive investment of manpower not only wastes valuable labor resources, but also significantly increases the overall manufacturing cost. Second, the quality of manual assembly is affected by the experience, proficiency, physical fitness, responsibility and even mood of the assembly personnel, so the consistency of the assembly quality cannot be guaranteed. Automation assembly can eliminate the above technical problems, and the first station of automation assembly is to extract and transfer the to-be-assembled shell from the vibration disc and the to-be-assembled shell input track of the structure system of the vibration disc connected to the vibration disc to the shell carrying mode, which is set on the rotary disc. The rotary disc is driven by the rotary disc driving mechanism set on the workbench and makes it rotate rhythmically.

[0004] The aforementioned shell feeding device must meet the complete cycle chain requirements of grabbing, moving, releasing and returning, because any delay or advance will affect the assembly rhythm. Although the "protector automatic assembly device with protector base extraction and release function" recommended by Chinese patent application CN106670803A introduces the protector base extraction and release mechanism, the structure and volume of the shell carrying mode (the patent application calls it "protector base carrying mechanism") are substantially different due to the different nature of the workpiece, so it has no reference significance for the shell feeding device planned by the present application to meet the cycle requirements.

The top of the lifting and lowering drive rod 14 of the housing clamping cylinder also corresponds to the left and right displacement signal acquisition devices 122 and 123 of the aforementioned lateral displacement fixing plate of the housing clamping cylinder. The lower end of the lifting and lowering drive rod 14 of the housing clamping cylinder is fixed to the upper front side of the lateral displacement guide rail 15 of the housing clamping cylinder, while the upper rear side of the lateral displacement guide rail 15 of the housing clamping cylinder forms a sliding pair with the lower front side of the aforementioned lateral displacement connecting plate 13 of the housing clamping cylinder.

The front end of the fixing rod connecting beam 17 is fixed to the housing extraction and release drive motor fixing plate connecting column 18 at the position corresponding to the lower part of the housing extraction and release drive motor fixing plate 12.

[0021] Please pay attention. Figure 1 The lower end of the aforementioned housing extraction and release drive motor fixing plate connecting column 18 is fixed to the housing extraction and release drive motor fixing plate connecting column fixing seat 181, while the upper end extends upward to the extent where the aforementioned housing extraction and release drive motor fixing plate 12 is located. The aforementioned housing extraction and release drive motor fixing plate connecting column fixing seat 181 is fixed to the upward-facing side of the aforementioned worktable 10.

[0022] The rear side of the aforementioned housing extraction and release drive motor fixing plate 12 is fixed to the upper end of the aforementioned housing extraction and release drive motor fixing plate connecting column 18 via the housing extraction and release drive motor fixing plate arm 121.

[0023] A transverse slide rail groove 124 is provided in a transverse state on the lower front side of the aforementioned housing extraction and release drive motor fixing plate 12.

The housing clamping cylinder transverse displacement connecting plate sliders 133 slide in cooperation with the aforementioned transverse slide rail 1241.

[0024] Depend on Figure 1As shown, a sliding block 134 for the lateral displacement guide rail of the housing clamping cylinder is fixed on the lower front side of the aforementioned housing clamping cylinder lateral displacement connecting plate 13 and at a position corresponding to the housing clamping cylinder lateral displacement guide rail 15. The upper rear side of the aforementioned housing clamping cylinder lateral displacement guide rail 15 and the sliding block 134 for the housing clamping cylinder lateral displacement guide rail form a sliding pair.

[0025] See you later Figure 1 A drive disc swing arm roller mating seat 141 is formed at the upper end of the aforementioned housing clamping cylinder lifting and lowering drive rod 14. A drive disc swing arm roller mating groove 1411 is formed on the rear side of the drive disc swing arm roller mating seat 141 and at the position corresponding to the aforementioned drive disc swing arm roller 11212. The drive disc swing arm roller 11212 and the drive disc swing arm roller mating groove 1411 form a rolling pair. A horizontal displacement fixing plate left and right displacement signal acquisition trigger rod 142 is fixed at the top of the drive disc swing arm roller mating seat 141 in a horizontal state. The horizontal displacement fixing plate left and right displacement signal acquisition trigger rod 142 corresponds between the aforementioned housing clamping cylinder horizontal displacement fixing plate left and right displacement signal acquisition devices 122 and 123.

[0026] The aforementioned housing clamping cylinder 16 is fixed to the lower end of a housing clamping cylinder fixing seat 162, while the upper end of the housing clamping cylinder fixing seat 162 is fixed to the lower front side of the housing clamping cylinder lateral displacement guide rail 15.

[0027] See you later Figure 1 In this embodiment, the front end of the aforementioned fixed rod connecting beam 17 is engaged and fixed with the aforementioned housing extraction and release drive motor fixing plate connecting column 18 at a position corresponding to the lower position of the aforementioned housing extraction and release drive motor fixing plate 12; the aforementioned pair of lateral displacement connecting plate left and right moving guide wheels 131 are each set on the upper part of the aforementioned housing clamping cylinder lateral displacement connecting plate 13 through the lateral displacement connecting plate left and right moving guide wheel shaft 1311.

[0028] In this embodiment, the aforementioned housing extraction and release drive motor 11 is a motor with forward and reverse rotation functions; the aforementioned housing clamping and placing cylinder 16 is a cylinder.

[0029] As a preferred embodiment, a limiting rod 135 is fixed in a lateral state at the lower front part of the aforementioned housing clamping cylinder lateral displacement connecting plate 13. The limiting rod 135 limits the downward position of the aforementioned drive disk swing arm roller mating seat 141, and more specifically, limits the outer surface of the groove bottom wall of the aforementioned drive disk swing arm roller mating groove 1411, so as to prevent the housing clamping cylinder vertical lifting drive rod 14 from exceeding the downward range.

[0030] Applicant combined Figure 1 and Figure 2The working principle of the housing extraction and release mechanism 1 of the present invention is described as follows: Under the instruction of an electrical controller (not shown in the figure) located at a reasonable position on the worktable 10, the housing extraction and release drive motor 11 operates. The housing extraction and release drive motor shaft 111 drives the housing clamping cylinder lateral displacement fixing plate drive disk 112, which is fixed to it by a set of screws, along with the drive disk swing arm 1121, to rotate. The drive disk swing arm roller shaft 11211 on the drive disk swing arm 1121 drives the drive disk swing arm roller 11212, which in turn forces the housing clamping cylinder lateral displacement connecting plate 13 to translate to the right. During the rightward translation, since the sliding pair relationship is formed between the housing clamping cylinder lateral displacement connecting plate slider 133 and the lateral slide rail 1241, the housing clamping cylinder lateral displacement connecting plate 13 exhibits smooth translation. Meanwhile, the two pairs of left and right moving guide wheels 131 of the lateral displacement connecting plate located on the upper rear side of the lateral displacement connecting plate 13 of the housing clamping cylinder and the disk edge 1122 of the lateral displacement fixing plate driving disk 112 of the housing clamping cylinder alternately form rolling pairs in a tangential manner. The alternation mentioned here means that when the right pair of the two pairs of left and right moving guide wheels 131 of the lateral displacement connecting plate forms a rolling pair with the disk edge 1122, the left pair withdraws from the relationship of forming a rolling pair with the disk edge 1122, and vice versa.

[0031] During the above process, since the drive disc swing arm roller 11212 engages with the drive disc swing arm roller mating groove 1411, it drives the housing clamping cylinder lifting and lowering drive rod 14 to move upward. Furthermore, since the lower end of the housing clamping cylinder lifting and lowering drive rod 14 is fixed to the housing clamping cylinder lateral displacement guide rail 15, its upward movement causes the housing clamping cylinder lateral displacement guide rail 15, along with the housing clamping cylinder fixing seat 162 and its fixed housing clamping cylinder 16, to also move upward accordingly. When the aforementioned housing clamping cylinder lateral displacement connecting plate 13 moves to the right to the point where the right end of the trigger rod 142 of the aforementioned lateral displacement fixing plate left and right displacement signal acquisition device can be acquired by the housing clamping cylinder lateral displacement fixing plate right displacement signal acquisition device 123 (using a photoelectric sensor), the housing to be assembled 30, which is still clamped by a pair of housing clamping cylinder jaws 161, is above the housing support mold 9 on the rotary table 20. At the same time, the aforementioned housing clamping cylinder lateral displacement fixing plate right displacement signal acquisition device 123 feeds the signal back to the electrical controller, and the electrical controller issues a working command to the housing clamping cylinder 16 to cause the pair of housing clamping cylinder jaws 161 to open, releasing the previously clamped housing to be assembled 30 into the housing support mold 9. Next, the electrical controller issues a command to reverse the housing extraction and release drive motor 11, performing the reverse operation process until the left position signal of the trigger rod 142 of the lateral displacement signal acquisition device of the housing clamping action cylinder is acquired by the left displacement signal acquisition device 122 of the lateral displacement fixing plate. During this process, the pair of housing clamping action cylinder grippers 161 mentioned above clamp the next (new) housing 30 to be assembled from the housing receiving seat 1042 at the upper end of the housing receiving seat support plate 104 (which will be mentioned below). After a delay set by the PLC, the electrical controller issues a command to the housing extraction and release drive motor 11 to work in reverse.

[0032] As can be seen from the above description of the working process of the housing extraction and release mechanism 1, when the housing clamping cylinder 16, which is a cylinder, descends and is at the top position corresponding to the housing receiving seat support plate 104, a pair of housing clamping cylinder jaws 161 clamp a housing 30 to be assembled that has been input from the housing input track 101 to the aforementioned housing receiving seat 1042, which has a transitional transfer platform effect and is located at the top of the housing receiving seat support plate 104. After clamping the housing 30 to be assembled, the housing clamping cylinder 16 moves upward and simultaneously moves to the right. When it moves to the position corresponding to the housing bearing mold 9 on the rotary table 20, it reverses to descend and releases the housing 30 to be assembled previously clamped by the pair of housing clamping cylinder jaws 161 into the housing bearing mold 9, then moves upward and moves to the left, and so on. The time taken by the aforementioned housing clamping cylinder 16 from clamping the housing 30 to be assembled from the housing receiving seat 1042 to releasing the clamped housing 30 into the housing bearing mold 9 and returning to the position corresponding to the housing receiving seat 1042 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 rotation and the next rotation of the aforementioned rotary table 20.

[0033] Depend on Figure 1 As shown, a housing receiving seat support plate 104, as mentioned above, is provided on the aforementioned workbench 10 at one end corresponding to the input track 101 of the housing to be assembled and facing the aforementioned rotary table 20. The lower end of the housing receiving seat support plate 104 is fixed to the workbench 10 via housing receiving seat support plate fixing feet 1041 (by means of screws). A housing receiving seat 1042, also mentioned above, is fixed to the upper end of the housing receiving seat support plate 104. The housing receiving seat 1042 is connected to the end face of the input track 101 of the housing to be assembled facing the aforementioned rotary table 20. Figure 1 As can be seen from the diagram, a housing receiving cavity 10421 for accommodating the housing 30 to be assembled is formed on the top of the aforementioned housing receiving seat 1042. The housing 30 to be assembled, which is input by the housing input track 101, enters the housing receiving cavity 10421 so that it can be picked up by the aforementioned pair of housing clamping cylinders 161, lifted, transferred and released onto the housing bearing mold 9 located on the rotary table 20.

[0034] A loading detection sensor 10422 is provided on the side of the aforementioned housing receiving seat facing the rotary table 20. The loading detection sensor 10422 communicates with and corresponds to the housing receiving cavity 10421 through a detection hole 10423 opened on the cavity wall of the housing receiving cavity 10421. When the housing 30 to be assembled is not fed into the housing receiving cavity 10421 within the time set by the PLC, the loading detection sensor 10422 feeds a signal back to the electrical controller. The electrical controller issues a command to stop the rotary table drive mechanism used to drive the rotary table 20. The online operator then checks the housing input track 101 and the vibratory feeder that provides the housing 30 to be assembled to the housing input track 101. For example, the operator checks whether there is no housing 30 to be assembled in the vibratory feeder, or whether the housing 30 to be assembled is blocked on the path of the housing input track 101.

[0035] After the present invention completes the release of the housing 30 to be assembled onto the housing support mold 9, the housing support mold 9, on which the housing 30 to be assembled is placed, rotates clockwise to the position corresponding to the rotation of the rotary table 20. Figure 1 The station shown is where the assembly shell missing detection mechanism 7, which belongs to the aforementioned automated assembly machine structure system, is located, so that the assembly shell missing detection mechanism 7 can detect whether there is an accidentally missing assembly shell 30.

[0036] Depend on Figure 1As shown, the aforementioned housing missingness detection mechanism 7 includes a housing missingness detection sensor fixing bracket column 71, a detection sensor fixing bracket column clamp 72, a housing missingness detection sensor fixing bracket 73, and a housing missingness detection sensor 74 (using a photoelectric sensor). The housing missingness detection sensor fixing bracket column 71 is longitudinally parallel to the rear side of the housing extraction and release drive motor fixing plate connecting column 18, and its lower end is fixed to the aforementioned workbench 10 through the housing missingness detection sensor fixing bracket column fixing seat 711, while its upper end is fixed to the rear end of the fixed connecting beam 17. The detection sensor fixing bracket column clamp 72 is positioned below the aforementioned fixed connecting beam 17 and is fixed to the housing missingness detection sensor fixing bracket column 71. A sensor mounting bracket 73 for detecting whether the housing is missing or not extends to one end of the mounting bracket column 71 of the sensor mounting bracket for detecting whether the housing is missing or not. The sensor mounting bracket extension plate 731 is fixed to the downward side of the aforementioned mounting bracket column clamp 72. The end of the mounting bracket 73 for detecting whether the housing is missing or not extends downward to the aforementioned rotary table 20, corresponding to the upper part of the aforementioned housing support mold 9. A pair of detection sensor support rod connecting arms 732 extends downward. The sensor for detecting whether the housing is missing or not is positioned in the middle of the sensor support rod 741 corresponding to the upper part of the housing support mold 9. The two ends of the sensor support rod 741 are positioned between the lower ends of the pair of detection sensor support rod connecting arms 732.

[0037] If, at the previous station, i.e., at the station where the aforementioned housing extraction and release mechanism 1 is located, although the probability is extremely low, it cannot consistently achieve 100% extraction and transfer of the housing 30 to be assembled into the housing support mold 9 on the rotary table 20. Therefore, when a shortage or error occurs, that is, once the aforementioned pair of housing clamping cylinders 161 fail to clamp (extract) the housing 30 to be assembled, since there is no housing 30 to be assembled on the housing support mold 9 at the station where the housing missing detection mechanism 7 is located, the housing missing detection sensor 74 senses it and feeds the signal back to the electrical controller. The electrical controller then issues a command to stop the aforementioned rotary table drive mechanism, and the online operator manually adds a housing 30 to be assembled onto the housing support mold 9, while simultaneously checking the housing extraction and release mechanism 1.

[0038] Depend on Figure 1 As can be seen from the schematic diagram, the housing extraction and release mechanism 1 of the present invention neither interferes with the housing input track 101 nor interferes with the adjacent housing missing detection mechanism 7.

[0039] In summary, the technical solution provided by this invention makes up for the shortcomings of the prior art, successfully completes the invention task, and accurately realizes the technical effects described by the applicant in the above technical effects column.
