Description

Technical Field

[0001] This utility model belongs to the field of automated assembly machinery technology for refrigeration compressor intake mufflers, specifically relating to a rotary table drive device for an intelligent assembly machine for intake mufflers. Background Technology

[0002] A fully enclosed refrigeration compressor seals the compressor main unit and motor together in a closed steel shell made of stamped and welded steel plates. This type of compressor is usually equipped with an intake silencer, which is essentially a Hermöller resonator. When the refrigeration compressor is working, the cylinder draws in refrigerant gas through the intake silencer. The intake silencer reduces the heating effect of the refrigerant when the compressor is heated, and also reduces the noise and vibration caused by pressure pulsation during the flow of refrigerant gas. This helps to reduce the operating noise of the compressor and effectively reduces the negative impact on the compressor efficiency.

[0003] Numerous technical information concerning refrigeration compressor suction silencers can be found in publicly available Chinese patent documents, such as CN105201781A (modular refrigeration compressor suction silencer), CN202645935U (a fully enclosed refrigeration compressor suction silencer), CN102720655A (refrigeration compressor suction silencer), CN102720653A (compressor suction silencer), CN105134555A (three-chamber parallel arrangement compressor suction silencer), CN104110358A (suction silencer and compressor having the same), and CN116006434A (suction silencer for refrigeration compressor with replaceable inlet and outlet pipes), etc.

[0004] Given that intake mufflers have few components and a relatively simple overall structure, they have traditionally been assembled manually. However, in recent years, the increasing scarcity of labor resources, the significant rise in labor costs, and the increasingly stringent quality requirements of refrigeration compressor manufacturers have forced intake muffler manufacturers to adapt their production models to conserve valuable labor resources, reduce labor costs, and ensure adequate assembly quality.

[0005] Undoubtedly, intelligent assembly, or automated assembly, can achieve the aforementioned goals of saving labor resources, reducing labor costs, and ensuring assembly quality.

[0006] In the structural system of the intake muffler, due to the constraints of the previous process, such as the demolding process of plastic molding, the intake pipe (also called the "connecting pipe" or "air guide pipe") can only be processed into a symmetrical two-part structure. Because the intake pipe is an irregularly shaped, long component, such as an S-shape or L-shape, it is relatively difficult to perform manual assembly with high quality and efficiency. The assembly of intelligent assembly machines requires a rhythmic process, and the alternating control of the action time and pause time in the start and stop rhythm of the rhythmic process is an important technical factor of intelligent assembly machines. In other words, how to make the rotary table of the intelligent assembly machine start and stop regularly and repeatedly according to the rhythm requirements set by the process is the key to ensuring the success of the automated assembly of the aforementioned intake pipe. The technical solution to be introduced below was developed in this context. Utility Model Content

The output shaft of the rotary table drive reduction gearbox corresponds to one end of the mounting plate. The drive belt passes through the rotary table drive reduction gearbox mounting plate. The drive pulley is fixed to the output shaft of the rotary table drive reduction gearbox. One end of the drive belt is fitted onto the drive pulley, and the other end is fitted onto the driven pulley.

[0011] In another specific embodiment of this utility model, the driving drive wheel and the driven drive wheel are pulleys, and the drive belt is a belt.

[0012] In another specific embodiment of this utility model, the rotary table drive motor is a servo motor or a stepper motor.

[0013] In another specific embodiment of this utility model, a set of suction pipe support molds are provided at equal intervals on the edge of the circumferential direction and the upward side of the turntable, and one end of the set of suction pipe support molds protrudes from the outer side of the turntable.

[0014] In a more specific embodiment of this utility model, the number of the set of suction pipe support molds is equal to the number of workstations in the entire process of assembling the suction pipe.

[0015] In a further specific embodiment of this utility model, the suction pipe support mold includes a suction pipe support base, a support base fixing plate, a first end limiting block of the suction pipe segment, and a suction pipe segment support base. The suction pipe support base is fixed to the upward-facing edge of the turntable, and one end of the suction pipe support base facing the first end limiting block of the suction pipe segment, together with the first end limiting block of the suction pipe segment, protrudes from the outer side of the turntable. The upward-facing side of the end of the suction pipe support base facing the center direction of the turntable constitutes a... A suction pipe support base block has a notch at one end facing the support base fixing plate, allowing the suction pipe section to extend into the notch. The support base fixing plate is also fixed to the upward-facing edge of the turntable on one side corresponding to the length of the suction pipe support base. The end of the support base fixing plate facing the suction pipe section support, along with the suction pipe section support, extends beyond the outer surface of the turntable to the same extent as the suction pipe support base. This extension occurs when the support base is fixed. A suction pipe lower tube wing plate adjustment slot is maintained between the plate and the opposite side of the suction pipe support base along the length direction. A suction pipe wing baffle is formed on the upper surface of the support base fixing plate on the side facing the suction pipe support base along the length direction. A suction pipe wing end support notch is formed on the upper surface of the end of this suction pipe wing baffle facing the suction pipe support base block, at a position corresponding to the insertion notch at the end of the suction pipe wing. A first end limiting block of the suction pipe wing is fixed to the outer side of the suction pipe support base protruding from the rotary table. On the side facing upwards, an arc-shaped cavity is formed on the side of the first end limiting block of the suction pipe segment facing the suction pipe support base block. The suction pipe segment support is fixed on the side of the support base fixing plate that protrudes from the outer side of the turntable and faces upwards, and maintains a distance between it and the suction pipe segment baffle. On the side of the suction pipe segment support facing the lower suction pipe segment baffle, a first end support step of the lower suction pipe segment is formed, and the upper surface of the suction pipe segment support is formed as the first end support surface of the upper suction pipe segment.

[0016] In another specific embodiment of this utility model, a support base fixing plate is provided with a support base fixing plate adjusting screw hole, and the support base fixing plate is fixed to the support base fixing plate adjusting screw hole provided on the rotary table by screws at the positions corresponding to the support base fixing plate adjusting screw holes; the suction pipe support base is fixed to the support base fixing plate by a pair of suction pipe support base fixing screws.

[0017] In another specific embodiment of this utility model, a set of suction pipe support base fixing screw holes are provided on the suction pipe support base, and screws are used to fix the suction pipe support base to the screw holes preset on the rotary table at the positions corresponding to the set of suction pipe support base fixing screw holes; a pair of suction pipe section first end limiting block screw holes are provided on the suction pipe section first end limiting block, and screws are used to fix the suction pipe section first end limiting block to the suction pipe support base at the positions corresponding to the pair of suction pipe section first end limiting block screw holes.

[0018] The technical solution provided by this utility model adopts a simple rotary table drive assembly. The sensor in the structural system of the rotary table drive assembly collects signals according to the rotation position of the signal disk. Whenever the gap in the signal disk that forms the signal channel corresponds to the sensor, the sensor acquires the signal and feeds it back to the electrical controller, causing the rotary table drive motor to stop working and the rotary table to stop rotating. Therefore, it can meet the requirement of the rotary table to start and stop in a regular, cyclical manner, and can realize the replacement of manpower with machines to save valuable labor resources, reduce labor costs in manufacturing, and ensure the assembly efficiency and quality of the intake pipe of the intake muffler.

Figure 3 This is a schematic diagram illustrating an application example of this utility model. Detailed Implementation

[0020] In order to better understand the technical essence and beneficial effects of this utility model, the applicant provides a detailed description below by way of embodiments. However, the description of the embodiments is not intended to limit the solution of this utility model. Any formal but not substantive equivalent transformations made based on the concept of this utility model should be considered within the scope of the technical solution of this utility model.

[0021] In the following description, all directional or orientational concepts involving up, down, left, right, front, and back are used in the context of the position of the figure being described and should not be construed as a specific limitation on the technical solution provided by this utility model.

[0022] Please see Figure 1 And combined Figure 3The figure shows the structure of an intelligent assembly machine for intake silencers. In the use state, a workbench 10 and a turntable 1 are set on the floor of the use site (work site). As shown in the figure, the bottom of the aforementioned workbench 10 has a set (four) support feet 108, which support the workbench 10 on the floor of the work site. The set of support feet 108 also has an adjustment function to ensure that the table surface, i.e. the upper surface, of the workbench 10 is fully level.

[0023] The rotary table drive assembly 101, showing the structural system of the rotary table drive device, includes a rotary table drive motor 1011, a rotary table drive reduction gearbox 1012, a drive pulley 1013, a drive belt 1014, a driven pulley 1015, a transmission box 1016, a signal disk 1017, and a sensor 1018. The rotary table drive motor 1011 is horizontally mounted and fixed to the rotary table drive reduction gearbox 1012, and is in transmission cooperation with the rotary table drive reduction gearbox 1012. The rotary table drive reduction gearbox 1012, together with the rotary table drive motor 1011... One end of the rotary table drive gearbox mounting plate 10122 is fixed to the rotary table drive gearbox mounting plate 10122, while the other end of the rotary table drive gearbox mounting plate 10122 is fixed to the side of the transmission box 1016 facing the driven transmission wheel 1015. The rotary table drive gearbox output shaft 10121 of the rotary table drive gearbox 1012 corresponds to one end of the aforementioned rotary table drive gearbox mounting plate 10122 and passes through the rotary table drive gearbox mounting plate 10122. The driving transmission wheel 1013 is fixed to the rotary table drive gearbox output shaft 10121, and one end of the transmission belt 1014 is sleeved on the driving transmission wheel 1013. The other end of the transmission belt 1014 is fitted onto the driven transmission wheel 1015. The driven transmission wheel 1015 is fixed to one end of the transmission box power input shaft 10161, which extends to one side of the transmission box 1016 housing. The other end of the transmission box power input shaft 10161 extends to the other side of the transmission box 1016 housing. The middle part of the transmission box power input shaft 10161 engages with the transmission box power output shaft 10162 of the transmission box 1016 via a gear (not shown in the figure, but easily understood based on common sense) inside the transmission box 1016. 62 extends upwards to the outside of the transmission box 1016, wherein the aforementioned transmission box 1016 is fixed on the aforementioned worktable 10, the central position of the aforementioned rotary disk 1 is fixed to the transmission box power output shaft 10162, the signal disk 1017 is fixed to the other end of the aforementioned transmission box power input shaft 10161, and a notch 10171 for forming a signal channel is formed on the signal disk 1017, and the sensor 1018 is set on the sensor mounting bracket 10181 at the position corresponding to the signal disk 1017, and the sensor mounting bracket 10181 is fixed to the aforementioned transmission box 1016.

[0024] A rotary table limiting post 10163 extends upward from the center of the upper surface of the aforementioned transmission power output shaft 10162. A limiting post mating hole 12 is opened at the center of the rotary table 1, and rotary table fixing screw holes 13 are spaced around the limiting post mating hole 12. The aforementioned rotary table limiting post 10163 extends into the limiting post mating hole 12. A rotary table fixing screw 131 is provided at the position corresponding to the aforementioned rotary table fixing screw hole 13. The rotary table fixing screw 131 is screwed into the transmission power output shaft screw hole 10164 provided on the aforementioned transmission power output shaft 10162.

[0025] In this embodiment, the aforementioned signal channel is an optical path channel (i.e., an optical channel), the aforementioned sensor 1018 is a photoelectric sensor, and the aforementioned sensor mounting bracket 10181 is a photoelectric sensor mounting bracket. When the aforementioned optical path channel corresponds to the aforementioned photoelectric sensor, the photoelectric sensor obtains a signal and feeds the signal back to the mounting bracket set by the optical sensor. Figure 3 The electrical controller 70 on the schematic workbench 10, equipped with a PLC (Programmable Logic Controller), causes the rotary table drive motor 1011 to stop for the required pause time of the aforementioned rotary table 1.

[0026] In this embodiment, the aforementioned driving drive wheel 1013 and driven drive wheel 1015 are pulleys, and correspondingly, the aforementioned drive belt 1014 is a belt. However, if the driving and driven drive wheels 1013 and 1015 are replaced with sprockets, and the drive belt 1015 is replaced with a chain, then it should be considered an equivalent change and still falls within the scope of the technical content disclosed in this utility model.

[0027] In this embodiment, the aforementioned rotary table drive motor 1011 is a servo motor, but a stepper motor can also be used.

[0028] Depend on Figure 1 and Figure 3 As shown, a set of suction pipe support molds 2 (i.e., molds for supporting suction pipes) are arranged at equal intervals on the edge of the rotary table 1 along its circumferential direction and facing upwards. One end of the set of suction pipe support molds 2 protrudes from the outer surface 11 of the rotary table 1. In this embodiment, the number of the aforementioned set of suction pipe support molds 2 is equal to the number of workstations, i.e., processes, in the entire process of assembling the suction pipe.

[0029] Please see Figure 3The aforementioned workstations or processes actually number eight, in the following order: the workstation where the lower suction tube segment extraction and release mechanism 3 is located (i.e., the corresponding workstation, the same below), the workstation where the lower suction tube segment missing detection mechanism 4 is located, the workstation where the upper suction tube segment extraction and release mechanism 5 is located, the workstation where the suction tube pressing mechanism 6 is located, the workstation where the suction tube finished product lifting mechanism 7 is located, the workstation where the retained suction tube detection mechanism 8 is located, the workstation where the retained suction tube removal mechanism 9 is located, and the workstation where the retained suction tube re-detection mechanism 60 is located. Since there are eight workstations, the number of the aforementioned set of suction tube bearing molds 2 is also correspondingly eight. Figure 1 Show).

[0030] The pause time required for the rotary table 1 to stop when the rotary table 1 is stopped by the electrical controller 70 mentioned above refers to the pause time during the rhythmic rotation of the rotary table 1. The pause time during the rhythmic rotation of the rotary table 1 is the time taken for the eight workstations to work simultaneously and synchronously. The working time of these eight workstations is consistent. For example, if the working time of one workstation is five seconds, then the other seven workstations will also work for five seconds. The pause time of the rotary table 1 is also five seconds. More specifically, the stop time of the rotary table drive motor 1011 is also five seconds.

[0031] When the rotary table drive motor 1011 is working, it drives the rotary table drive reduction gearbox 1012. The output shaft 10121 of the rotary table drive reduction gearbox 1012 drives the drive pulley 1013. The drive pulley 1013 drives the driven pulley 1015 via the transmission belt 1014. The driven pulley 1015 drives the transmission box power input shaft 10161 of the transmission box 1016. The power input shaft 10161 of the transmission box and located on the drive pulley 10161... The power input shaft gear of the aforementioned gear in the transmission box 1016 drives the gear on the power output shaft 10162 of the transmission box, causing the power output shaft 10162 to rotate. Since the rotary table 1 is fixed to the upper end of the power output shaft 10162 of the transmission box by the rotary table fixing screw 131, and since the fixing plate limiting post 10163 is engaged with the limiting post mating hole 12, the power output shaft 10162 of the transmission box drives the rotary table 1 to rotate rhythmically counterclockwise. As mentioned above, the rhythmic rotation of the rotary table 1 depends on the rhythmic operation of the rotary table drive motor 1011, and the rhythmic operation of the rotary table drive motor 1011 depends on the correspondence between the aforementioned notch 10171 and the sensor 1018. Since this has been explained above, it will not be repeated. However, it should be noted that each time the rotary table drive motor 1011 works, it needs to ensure that the time spent by the rotary table 1 rotating from one station to another is sufficient.

[0032] Please see Figure 2 And combined Figure 1 and Figure 3 The aforementioned suction pipe support mold 2 includes a suction pipe support base 21, a support base fixing plate 22, a first end limiting block 23 for the suction pipe segment, and a suction pipe segment support base 24. The suction pipe support base 21 is fixed to the upward-facing edge of the aforementioned rotary table 1, and one end of the suction pipe support base 21 facing the first end limiting block 23, together with the first end limiting block 23, protrudes from the outer surface 11 of the rotary table 1. An upward-facing end of the suction pipe support base 21 facing the center of the rotary table 1 forms a suction pipe support base stop 211. One end of the support base fixing plate 22 has a notch 2111 for inserting the end of the suction pipe segment. The support base fixing plate 22 is also fixed to the upward-facing edge of the turntable 1 on the side corresponding to the length direction of the suction pipe support base 21. One end of the support base fixing plate 22, along with the suction pipe segment support base 24, protrudes beyond the outer surface 11 of the turntable 1, and the degree to which it protrudes is the same as the degree to which the suction pipe support base 21 protrudes beyond the outer surface 11 of the turntable. The support base fixing plate 22 and the suction pipe support base 21 are aligned along their length directions. A suction pipe lower tube wing plate adjustment slot 25 is maintained between one side, and a suction pipe wing flange 221 is formed on the upper surface of the support base fixing plate 22 facing the suction pipe bearing base 21 along its length. A suction pipe wing flange 221 is formed on the upper surface of the suction pipe wing flange 221 facing the aforementioned suction pipe bearing base stop block 211, and at a position corresponding to the aforementioned suction pipe wing end insertion notch 2111. The first end limiting block 23 of the suction pipe lower tube is fixed to the upward-facing side of the end of the suction pipe bearing base 21 protruding from the outer side 11 of the rotary table. An end limiting block 23, facing the suction pipe support base block 211, forms a suction pipe sleeve mating arc cavity 231. A suction pipe sleeve support 24 is fixed to the side of the aforementioned support base fixing plate 22 protruding from the outer side 11 of the rotary table, facing upwards, and maintains a distance equal to the outer diameter of the lower suction pipe sleeve 20 between it and the aforementioned suction pipe sleeve edge 221. A first end support step 241 for the lower suction pipe sleeve is formed on the side of the suction pipe sleeve support 24 facing the suction pipe sleeve edge 221, and the upper surface of the lower suction pipe sleeve support 24 forms the first end support surface 242 for the upper suction pipe sleeve. The support and positioning of the upper and lower suction pipe sleeves 30 and 20 on the suction pipe support mold 2 can also be achieved by... Figure 2For example, when the lower intake tube wing plate 201, which will be mentioned below, is inserted into the lower intake tube wing plate adjustment slot 25, the part of the lower intake tube 20 corresponding to the intake tube wing edge 221 abuts against the intake tube wing edge 221, that is, it abuts against the intake tube wing edge 221.

[0033] Depend on Figure 2 As shown, the aforementioned support base fixing plate 22 has adjustment screw holes 222, commonly referred to as waist-shaped holes or elliptical holes. Screws are used to fix the support base fixing plate 22 to the adjustment screw holes pre-set on the rotary table 1 at positions corresponding to these holes. Because the adjustment screw holes 222 are elliptical in shape, the width of the aforementioned intake pipe lower tube flange adjustment slot 25 can be adjusted as needed. The aforementioned intake pipe lower tube flange support 24 is fixed to the support base fixing plate 22 by a pair of intake pipe lower tube flange support fixing screws 243. Figure 2 The diagram also shows a set of suction pipe support base fixing screw holes 212 formed on the suction pipe support base 21, through which screws fix the suction pipe support base 21 to the screw holes pre-set on the aforementioned rotary table 1 at the positions corresponding to the set of suction pipe support base fixing screw holes 212; Figure 2 The diagram shows a pair of first end limit block screw holes 232 on the first end limit block 23 of the aforementioned air pipe segment. The first end limit block 23 of the air pipe segment is fixed to the aforementioned air pipe support base 21 by screws at positions corresponding to the pair of first end limit block screw holes 232 of the air pipe segment.

[0034] See also Figure 2 To facilitate understanding of this utility model, the upper suction tube 30 and lower suction tube 20 constituting the finished suction tube 40 are shown. The lower suction tube 20 has a lower suction tube wing 201 with a lower suction tube wing rib 2011, and the upper suction tube 30 has an upper suction tube wing 301. When the aforementioned lower suction tube extraction and release mechanism 3 is working, it clamps and releases the lower suction tube wing rib 2011 at its central position along its length. Figure 2 The illustration clearly confirms that the aforementioned lower intake pipe flange 201 is fitted into the aforementioned lower intake pipe flange adjustment slot 25 during assembly. Figure 2 The diagram also shows a lower tube tenon 202 formed on the lower tube segment 20 of the intake pipe and an upper tube tenon 302 (with a mortise hole) formed on the upper tube segment 30 of the intake pipe. The upper and lower tube tenons 302 and 202 are fitted together by the aforementioned intake pipe pressing mechanism 6 to form a tenon-mortise fit, or mortise and tenon fit, thereby forming the intake pipe finished product 40 that can be installed into the housing of the muffler. Due to Figure 2The structure of the finished suction tube 40 shown is prior art. For example, please refer to CN116006434A and CN104110358A mentioned by the applicant in the background section above, etc., and therefore the applicant will not elaborate further. The aforementioned upper and lower suction tubes 30 and 20 are supplied to the vibratory feeder after being manufactured in the previous process.

[0035] Depend on Figure 3 As shown, the aforementioned workbench 10 has a box-shaped structure with a workbench cavity. A workbench cavity protective door 102 for opening or closing the workbench cavity is provided on the front side of the workbench 10. A main power control switch 103 is provided on the right wall of the workbench cavity. An air filter device 104 for filtering the pressurized air from the pressurized air generation device is provided on the right side of the workbench cavity. A pressurized air pipeline through hole 105 is provided on the table surface of the workbench 10 for the pipeline that provides pressurized air to the working cylinder. A suction pipe finished product outlet groove 106 is provided at an inclined state on the table surface of the workbench 10, and a retained suction pipe outlet groove 107 is also provided at an inclined state, accompanying the retained suction pipe removal mechanism 7 mentioned above.

[0036] The applicant should note that the aforementioned workbench cavity shielding door 102 can also be installed on the rear side of the workbench 10, or on both the front and rear sides of the workbench 10. The aforementioned main power control switch 103 can also be installed on the left cavity wall of the workbench cavity.

[0037] Applicant combined Figures 1 to 3Briefly describing the entire working process of this utility model, at the aforementioned suction pipe lower tube fragment extraction and release mechanism 3 (which can be referred to as the first station), the suction pipe lower tube fragment 20, which originates from the vibratory feeder and is input through the suction pipe lower tube fragment input track 80a, is extracted and placed into the suction pipe carrying mold 2 on the rotary table 1. When the suction pipe carrying mold 2 on the rotary table 1, carrying the suction pipe lower tube fragment 20, rotates to the position corresponding to the suction pipe lower tube fragment missing detection mechanism 4, which serves as the second station, it performs the detection. If a fragment is missing, the machine stops, and the operator replenishes it; otherwise, the rotary table 1 continues to rotate. When the suction pipe support mold 2, carrying the lower suction pipe segment 20, rotates to the position of the suction pipe upper pipe segment extraction and release mechanism 5 (which serves as the third station), the upper suction pipe segment 30, which originates from the vibratory feeder and is input from the upper suction pipe segment input track 80b, is engaged with the lower suction pipe segment 20 by the upper suction pipe segment extraction and release mechanism 5 in a manner similar to that of the lower suction pipe segment extraction and release mechanism 3. When the rotary table 1 rotates the suction pipe support mold 2, carrying the upper and lower suction pipe segments 30 and 20 in their engaged state, to the position of the suction pipe pressing mechanism 6 (which serves as the fourth station), the upper and lower suction pipe segments 30 and 20 are pressed together with a tenon-and-mortise-like fit to form the finished suction pipe 40. Figure 3 (Illustration). Next, when the rotary table 1 rotates the suction pipe bearing mold 2 carrying the suction pipe finished product 40 to the suction pipe finished product lifting mechanism 7, which serves as the fifth station, the suction pipe finished product 40 is extracted and released into the suction pipe finished product outlet groove 106, and then discharged from the suction pipe finished product outlet groove 106. The aforementioned upper and lower suction pipe segments 30 and 20 are obtained from the previous molding process.

[0038] Normally, the suction pipe bearing mold 2, which leaves the suction pipe finished product lifting mechanism 7 as the rotary table 1 rotates, should be in an empty mold state. The so-called empty mold state means that there are no workpieces, that is, there are no suction pipe finished products 40 that have not been removed. However, the aforementioned empty mold state cannot be absolutely or foolproofly eliminated, because in the actual use of the equipment, either of the following two situations may occur: First, the suction pipe finished product 40 is not removed; second, due to the failure of the upper and lower pipe segments 30 and 20 to connect properly or the lack of reliability in pressing them together, the suction pipe finished product lifting mechanism 7 only lifts the upper pipe segment 30, while the lower pipe segment 20 remains on the suction pipe bearing mold 2. Therefore, as the rotary table 1 rotates and rotates to the position corresponding to the sixth station where the stagnant suction pipe detection mechanism 8 is located, the stagnant suction pipe detection mechanism 8 uses the same detection principle as the aforementioned suction pipe lower tube missing detection mechanism 4 to detect whether there is a stagnant suction pipe 50, and feeds back the signal of the presence of a stagnant part to the electrical controller 70. The electrical controller 70 sends a signal to the stagnant suction pipe removal mechanism 9, which is the seventh station. When the suction pipe bearing mold 2 with the stagnant suction pipe finished product 40 or suction pipe lower tube 20 is rotated to the position of the stagnant suction pipe removal mechanism 9, the stagnant suction pipe removal mechanism 9 extracts the stagnant part on the suction pipe bearing mold 2 and releases it into the stagnant suction pipe outlet groove 107, and it is then discharged from the stagnant suction pipe outlet groove 107. As the rotary table drive assembly 101 continues to rotate the rotary table 1, the suction pipe support mold 2, which originally corresponded to the retained suction pipe removal mechanism 9, is aligned with the position of the retained suction pipe re-detection mechanism 60, which serves as the eighth station. If there are suction pipe finished products 40 or suction pipe lower segments 20 that have not been removed by the retained suction pipe removal mechanism 9, then the retained suction pipe re-detection mechanism 60 will handle them in the same way as the aforementioned suction pipe lower segment missing detection mechanism 4, and the operator will remove the retained suction pipe from the suction pipe support mold 2. This process is repeated cyclically, and the operation of the entire equipment is achieved by the online operator (one person can simultaneously monitor multiple devices) by operating the corresponding buttons on the electrical controller 70. After assembly, the finished suction pipe 40 is discharged from the finished suction pipe discharge slot 106 and supplied to the subsequent process for assembly with the suction muffler housing.

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