Description

Technical Field

[0001] This utility model belongs to the field of automated assembly machinery technology for refrigeration compressor parts, specifically relating to an intelligent automatic assembly device for the intake pipe of a refrigeration compressor intake muffler. Background Technology

[0002] The aforementioned suction pipe can also be called a "connecting pipe" or "gas guide pipe." A fully enclosed refrigeration compressor, in which the compressor's main unit (motor and compression mechanism) and the motor are sealed together in a closed steel shell made of stamped and welded steel plates, typically has a suction muffler inside, essentially a Hermöller resonator. When the refrigeration compressor is working, the cylinder draws in refrigerant gas through the suction muffler. The suction muffler both reduces the heating effect of the refrigerant when the compressor heats up internally and reduces the noise and vibration caused by pressure pulsations during refrigerant gas flow, thus helping to reduce compressor operating noise and effectively minimizing negative impacts on compressor efficiency.

[0003] Because of their positive effects, which are not limited to those mentioned above, intake mufflers have always attracted industry attention, and technical information on improving the noise reduction performance of intake mufflers using various technological means is frequently found in patent and non-patent literature. Adding silencing chambers to a cavity formed by a shell and a cover, or a cavity formed directly by the shell without a cover, is generally considered a beneficial measure to improve noise reduction. Typical examples include mufflers with two or three silencing chambers, such as CN102720655A (refrigeration compressor intake muffler) and CN102720653A (compressor intake muffler) for the former, and CN105134555A (three-chamber parallel arrangement compressor intake muffler) for the latter. Changes in the number and position of the aforementioned silencing chambers will correspondingly change the shape and installation method of the intake pipe in the muffler's structural system. A wing plate (also called a "support plate" or "silencing cavity partition") extending on the intake pipe for insertion into a slot on the cavity wall of the housing cavity can both meet the requirement of separating the silencing cavity and facilitate installation. A typical example is the "intake silencer and compressor having the same" recommended in CN104110358A, and a more typical example is the "intake silencer of a refrigeration compressor with replaceable inlet and outlet pipes" provided in CN116006434A (this patent application was filed by the applicant).

[0004] Due to manufacturing process limitations, the aforementioned intake pipe is first processed into two symmetrical structures, and then the two structures are joined face to face in a subsequent process to form an integral structure in order to meet the installation requirements with the housing.

[0005] Because there is currently a lack of specialized machinery for assembling the aforementioned two-part suction pipe structure, manufacturers of refrigeration compressor suction mufflers can only rely on manual assembly. The disadvantages of manual assembly are: first, it is difficult to guarantee assembly quality, because manual assembly by workers introduces human differences. Factors causing these differences are related to the operator's experience, skills, sense of responsibility, and even emotions. In particular, even with the same worker, it is impossible to ensure consistent assembly results; second, assembly efficiency is low, affecting the overall production capacity of refrigeration compressor suction mufflers; third, labor costs are relatively high; and fourth, it is insufficient to save valuable labor resources, etc.

[0006] Undoubtedly, mechanized assembly can overcome the aforementioned disadvantages. However, because such automated machinery is characterized as non-standard equipment specifically designed for assembling certain products, it is often designed and manufactured by the manufacturers of these products themselves, or designed and then outsourced to relevant manufacturers with manufacturing capabilities.

[0007] Based on the above factors, the applicant made a beneficial design, which resulted in the technical solution that will be introduced below. Utility Model Content

A suction tube upper segment extraction and release mechanism for releasing the extracted upper suction tube segment 30 onto the suction tube support mold 2 carrying the lower suction tube segment 20 and aligning the upper suction tube segment 30 and the lower suction tube segment 20 (i.e., face-to-face engagement, hereinafter the same). 5.

[0025] As can be seen from the above description, this utility model actually has eight workstations, which are, in 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 and Figure 2 (See illustration). Undoubtedly, the aforementioned rotary table 1 rotates rhythmically.

[0026] Please see Figure 2 And combined Figure 1The aforementioned rotary table drive mechanism 101 includes a rotary table drive motor 1011, a rotary table drive reduction gearbox 1012, a drive pulley 1013, a transmission belt 1014, a driven pulley 1015, a transmission box 1016, a signal disk 1017, and a photoelectric 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, is fixed to one end of the rotary table drive reduction gearbox mounting plate 10122. The other end of 122 is fixed to the side of the transmission box 1016 facing the driven transmission wheel 1015. The rotary drive gearbox output shaft 10121 of the rotary drive gearbox 1012 corresponds to one end of the aforementioned rotary drive gearbox mounting plate 10122 and passes through the rotary drive gearbox mounting plate 10122. The driving transmission wheel 1013 is fixed to the rotary drive gearbox output shaft 10121. One end of the transmission belt 1014 is sleeved on the driving transmission wheel 1013, and the other end of the transmission belt 1014 is sleeved on the driven transmission wheel 1015. The driven transmission wheel 1015 is connected to the housing extending to the transmission box 1016. One end of the transmission power input shaft 10161 is fixed on one side, and the other end extends to the other side of the transmission housing 1016. The middle part of the transmission power input shaft 10161 engages with the transmission output shaft 10162 of the transmission housing 1016 via a gear (not shown in the figure, but easily understood based on common sense) inside the transmission housing 1016. The transmission output shaft 10162 extends upwards out of the transmission housing 1016. The aforementioned transmission housing 1016 is fixed to the aforementioned worktable 10, and the aforementioned transmission output shaft 10162... A rotary table limiting post 10163 extends upward from the center of the surface. A signal disk 1017 is fixed to the other end of the aforementioned transmission box power input shaft 10161. A notch 10171 for forming an optical path is formed on the signal disk 1017. A photoelectric sensor 1018 is mounted on a photoelectric sensor mounting bracket 10181 at a position corresponding to the signal disk 1017. The photoelectric sensor mounting bracket 10181 is fixed to the aforementioned transmission box 1016. When the aforementioned notch 10171 corresponds to the aforementioned photoelectric sensor 1018, the photoelectric sensor 1018 obtains a signal and feeds the signal back to the optical path. Figure 1The electrical controller 70 on the schematic workbench 10 stops the rotary table drive motor 1011 for the required pause time. 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 box power output shaft screw hole 10164 provided on the aforementioned transmission box power output shaft 10162.

[0027] 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.

[0028] 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.

[0029] 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 photoelectric 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.

[0030] Please see Figure 3 And combined Figure 1 and Figure 2The 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 211 facing the support base fixing plate 22 is provided with an insertion notch 2111 for the end of the suction pipe. 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 bearing base 21. One end of the support base fixing plate 22 facing the suction pipe bearing base 24, together with the suction pipe bearing base 24, protrudes beyond the outer surface 11 of the turntable 1, and the degree to which it protrudes beyond the outer surface 11 of the turntable is the same as the degree to which the suction pipe bearing base 21 protrudes beyond the outer surface 11 of the turntable. The length direction of the support base fixing plate 22 and the suction pipe bearing base 21 are... An adjustment slot 25 for the lower suction pipe section is maintained between one side, and a suction pipe section flange 221 is formed on the upper surface of the support base fixing plate 22 facing the suction pipe support base 21 along its length. A suction pipe section end support notch 2211 is formed on the upper surface of the suction pipe section flange 221 facing the aforementioned suction pipe support base stop block 211, at a position corresponding to the aforementioned suction pipe section end insertion notch 2111. A first end limiting block 23 of the suction pipe section is fixed to the upward-facing side of the end of the suction pipe support base 21 protruding from the outer side 11 of the rotary table. The first end limiting block 23, facing the suction pipe support base block 211, forms a suction pipe sleeve mating arc cavity 231. The 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 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 be determined by… Figure 5 Detailed explanation. For 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.

[0031] 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 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 3 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 preset screw holes on the rotary table 1. Figure 3 The diagram shows a pair of first end limit block screw holes 232 of the lower end limit block of the aforementioned air pipe, which are opened on the first end limit block 23 of the aforementioned air pipe. The first end limit block 23 of the air pipe is fixed to the aforementioned air pipe support base 21 by screws at the positions corresponding to the first end limit block screw holes 232 of the lower end limit block of the aforementioned air pipe.

[0032] Please see Figure 7 And continue to see Figure 3 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, and the upper suction tube 30 has an upper suction tube wing 301. From Figure 3 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 3 and Figure 7 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 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-and-mortise fit, or mortise-and-mortise fit, thereby forming the finished intake pipe 40 that can be installed into the housing of the muffler. Due to Figure 3 and Figure 7 The structure of the inhalation tube finished product 40 shown is prior art. For example, you can refer to CN116006434A and CN104110358A mentioned by the applicant in the background art section above, etc. Therefore, the applicant will not elaborate further.

A lower pipe section storage seat fixing plate 311 is fixed to the top of the aforementioned lower pipe section receiving bracket 31. A suction pipe lower pipe section storage mold 3111 with the same structure as the aforementioned suction pipe bearing mold 2 is provided on the left end of the upper side of the lower pipe section storage seat fixing plate 3111. A suction pipe lower pipe section receiving mold 31 is provided on the right end of the upper side of the suction pipe lower pipe section storage mold 3111. 12. A mold protrusion 31121 is fixed to the left end of the mold 3112 facing upward on the side of the lower tube of the suction pipe.

The lower tube extraction feeding cylinder 32 is fixed longitudinally to the front right end of the synchronous lifting fixing plate 34 of the lower tube extraction rotating cylinder. The lower part of the lower tube extraction feeding cylinder 32 has a pair of lower tube extraction grippers 321. The mold-operating cylinder 33 is located to the left of the lower tube extraction and feeding mold-operating cylinder 32, and the lower tube extraction and mold-operating cylinder 33 is fixed longitudinally to the left front side of the synchronous lifting and fixing plate 34 of the lower tube extraction and mold-operating cylinder.

The feeding lateral displacement action cylinder fixing plate fixing seat 371 is fixed to the aforementioned feeding lateral displacement action cylinder fixing plate connecting plate 31211. Figure 1 The structure of the aforementioned upper tube extraction and release mechanism 5 is the same as that of the lower tube extraction and release mechanism 3.

[0034] The function of the aforementioned receiving mold protrusion and concave cavity 31122 can be derived from... Figure 1 Specifically, it is disclosed that the lower tube end 203 (of the aforementioned lower tube 20) is used for supplying the aforementioned lower tube 20. Figure 3 (Illustrated) Embedded, the aforementioned suction pipe lower tube wing plate receiving groove 31123 is obviously for the suction pipe lower tube wing plate 201 to be received. Of course, the lower tube end 203 must match the aforementioned suction pipe end insertion notch 2111.

[0035] See you later Figure 4 A sliding plate block 3511 is fixed on the left side of the aforementioned synchronous lifting and fixing plate cylinder's upper and lower sliding plates 351. A synchronous lifting and fixing plate cylinder's upper and lower sliding plate downward limit position adjusting screw seat 352 is fixed on the lower left side of the aforementioned synchronous lifting and fixing plate cylinder 35. A synchronous lifting and fixing plate cylinder's upper and lower sliding plate downward limit position adjusting screw 352 is provided on the synchronous lifting and fixing plate cylinder's upper and lower sliding plate downward limit position adjusting screw seat 352 at a position corresponding to the lower surface of the aforementioned sliding plate block 3511.

The aforementioned lower tube extraction mold feeding cylinder 32, lower tube mold rotation cylinder 33, synchronous lifting fixing plate cylinder 35 and loading lateral displacement cylinder 38 are cylinders.

[0036] See you later Figure 1 and Figure 4 ,exist Figure 1 The diagram shows the lower intake tube input track 80a and the upper intake tube input track 80b. The upper and lower intake tube input tracks 80b and 80a are respectively connected to... Figure 1 The vibratory feeder, not shown, is connected to the upper and lower tubes 30 and 20 of the suction pipe. Since the aforementioned vibratory feeder is a conventional technology and is frequently seen in published Chinese patent documents, such as Chinese Patent ZL202111116671.0 (Automatic Assembly Device for Current Starter), the applicant has not included the vibratory feeder in the figure.

[0037] The vibratory feeder conveys air to the lower pipe of the suction pipe via the input track 80a. Figure 3 and Figure 7The lower intake pipe section 20 shown has a guide groove 80c on its bottom wall that corresponds to and is aligned with the aforementioned lower intake pipe section wing plate adjustment slot 25. Therefore, the lower intake pipe section 20 travels along the guide groove 80c to the aforementioned lower intake pipe section receiving mold 3112. In this state, the lower intake pipe section wing plate 201 of the lower intake pipe section 20 is in a sliding engagement with the lower intake pipe section wing plate adjustment slot 25. At this time, the synchronous lifting and fixing plate action cylinder 35 works, causing the upper and lower sliding plates 351 of the synchronous lifting and fixing plate action cylinder, together with the synchronous lifting and fixing plate connecting plate 341, to move downward. The downward movement of the synchronous lifting and fixing plate connecting plate 341 simultaneously drives the lower tube extraction and feeding action cylinder 32 and the lower tube rotation action cylinder 33 to move downward. At this time, the operation of the lower tube extraction feeding cylinder 32 causes a pair of lower tube extraction grippers 321 to clamp the rib 2011 of the suction tube lower tube wing 201 of the suction tube lower tube 20 at the center position along the length direction. At the same time, the operation of the lower tube mold turning cylinder 33 causes a pair of lower tube mold turning grippers 331 to clamp the rib 2011 of the suction tube lower tube wing 201 of the suction tube lower tube 20 at the center position along the length direction on the suction tube lower tube wing 201 of the suction tube lower tube wing 201 located on the suction tube lower tube storage mold 3111. Next, the aforementioned synchronous lifting and fixing plate action cylinder 35 reverses its operation, causing the synchronous lifting and fixing plate action cylinder sliding plate 351, along with the synchronous lifting and fixing plate connecting plate 341, to move upward. Simultaneously, the synchronous lifting and fixing plate connecting plate 341 moves upward, driving the lower pipe segment extraction and feeding action cylinder 32 and the lower pipe segment rotation action cylinder 33, each clamping a lower suction pipe segment 20, to move upward. This lifts the lower suction pipe segment 20, previously located on the lower suction pipe segment storage mold 3111 and the lower suction pipe segment receiving mold 3112, away from them. At the same time, another lower suction pipe segment 20 is input from the lower suction pipe segment input track 80a into the lower suction pipe segment receiving mold 3112.In the aforementioned state, the feeding lateral displacement cylinder 38 operates, causing the feeding lateral displacement cylinder sliding plate 381, which is slidably engaged with it, to move towards the rotary table 1. This causes the synchronous lifting and fixing plate cylinder left and right displacement fixing seat 36, which is fixed to the feeding lateral displacement cylinder sliding plate 381, to also move towards the rotary table 1. Thus, the synchronous lifting and fixing plate cylinder 35, the lower tube extraction and mold-turning cylinder synchronous lifting and fixing plate 34, together with the lower tube extraction and feeding cylinder 32 and the lower tube rotation cylinder 33, which are mounted on the same carrier, to move to the left, i.e., towards the rotary table 1. This causes the lower tube rotation cylinder 33, which clamps the lower tube 20 of the suction pipe, to be positioned above the suction pipe bearing mold 2 on the rotary table 1, while the lower tube extraction and feeding cylinder 32, which clamps the lower tube 20 of the suction pipe, is positioned above the lower tube storage mold 3111 of the suction pipe.

[0038] In the aforementioned state, the lower suction tube 20 previously located on the suction tube receiving mold 3112 is lifted and transferred above the lower suction tube storage mold 3111, and the lower suction tube 20 previously located on the lower suction tube storage mold 3111 is lifted and transferred above the suction tube bearing mold 2. At this time, the aforementioned synchronous lifting and fixing plate action cylinder 35 operates again, causing the synchronous lifting and fixing plate action cylinder sliding plate 351, together with the lower tube extraction and mold-turning action cylinder synchronous lifting and fixing plate 34 set on the same carrier, and the aforementioned lower tube extraction and feeding action cylinder 32 and lower tube mold-turning action cylinder 33 set on the same carrier as the lower tube extraction and mold-turning action cylinder synchronous lifting and fixing plate 34, to descend, so that the suction pipe lower tube 20, which is clamped by a pair of lower tube extraction claws 321, corresponds to the suction pipe lower tube storage mold 3111, and the suction pipe lower tube wing plate 201 is inserted into the suction pipe lower tube wing plate receiving groove 31123. At the same time, the suction pipe lower tube 20, which is clamped by a pair of lower tube mold-turning claws 331, corresponds to the suction pipe bearing mold 2, and the suction pipe lower tube wing plate 201 is inserted into the suction pipe lower tube wing plate adjustment slot 25. Next, the aforementioned lower tube extraction and feeding cylinder 32 and lower tube rotation cylinder 33 operate simultaneously, causing the pair of lower tube extraction grippers 321 and the pair of lower tube rotation grippers 331 to open and release the lower tube 20 of the suction pipe. Then, the synchronous lifting and fixing plate cylinder 35 operates in the opposite direction, causing the upper and lower sliding plates 351 of the synchronous lifting and fixing plate cylinder, along with the aforementioned lower tube extraction and rotation cylinder synchronous lifting and fixing plate 34 mounted on it, and the lower tube extraction and feeding cylinder 32 and lower tube rotation cylinder 33 mounted on the lower tube extraction and rotation cylinder synchronous lifting and fixing plate 34, to move upwards accordingly. Next, the aforementioned lateral displacement cylinder 38 reverses its operation, causing the sliding plate 381 of the lateral displacement cylinder to move to the right, i.e., to move away from the rotary table 1. This causes the aforementioned lower tube extraction and feeding cylinder 32 and lower tube rotation cylinder 33 to be positioned above the aforementioned suction pipe lower tube receiving mold 3112 and suction pipe lower tube storage mold 3111, respectively. By repeating the aforementioned action process, the required number of suction pipe lower tubes 20 to be assembled can be transferred to the suction pipe carrying mold 2 in a relay manner.

[0039] The applicant mentioned above Figure 1 The structure of the upper inhalation tube extraction and release mechanism 5 shown is the same as that of the lower inhalation tube extraction and release mechanism 3. Therefore, the working principle or action process of the upper inhalation tube extraction and release mechanism 5 is the same as that of the lower inhalation tube extraction and release mechanism 3 described in detail above. The only difference in form is as follows: the upper inhalation tube extraction and release mechanism 5 extracts and releases the material from the upper inhalation tube. Figure 1 and Figure 3 as well as Figure 7The upper tube segment 30 of the suction tube shown is equivalent to the upper tube segment extraction and release mechanism 5 of the suction tube upper tube segment extraction and release mechanism 5 mentioned above. The pair of upper tube segment grippers are plate-shaped so that they can reliably clamp or release the middle part of the suction tube upper tube segment 30 input by the upper tube segment input track 80b in the length direction.

[0040] Please pay close attention. Figure 1 The aforementioned inhalation tube missing section detection mechanism 4 includes an inhalation tube missing section detection sensor mounting post 41, an inhalation tube missing section detection sensor mounting base 42, and an inhalation tube missing section detection sensor 43. The inhalation tube missing section detection sensor mounting post 41 is arranged longitudinally, and its lower end is fixed to the aforementioned worktable 10, while its upper end extends upward away from the worktable 10. The inhalation tube missing section detection sensor mounting base 42 is suspended above the edge of the aforementioned rotary table 1 and is vertically and adjustablely fixed to the upper end of the inhalation tube missing section detection sensor mounting post 41 by mounting base screws 421. 2. A sensor position adjustment guide block 422 is formed on the upper part of the end away from the rotary table 1. The sensor 43 for detecting whether the lower part of the suction tube is missing is adjusted and set on the sensor fixing base 42 for detecting whether the lower part of the suction tube is missing, corresponding to the position of the sensor position adjustment guide block 422. The sensor detection head 431 of the sensor 43 for detecting whether the lower part of the suction tube is missing is located above the aforementioned suction tube support mold 2. The sensor 43 for detecting whether the lower part of the suction tube is missing is electrically connected to the electrical controller 70 set on the aforementioned workbench 10 through a circuit in the use state. Since the structure of the aforementioned residual suction tube detection mechanism 8 and the residual suction tube retention re-detection mechanism 60 is the same as the structure of the sensor 4 for detecting whether the lower part of the suction tube is missing, the applicant will not describe them in detail.

[0041] When the lower suction tube segment 20 is missing from the suction tube support mold 2 at the second work station, which corresponds to the work station of the suction tube segment missing detection mechanism 4 (that is, when the suction tube segment extraction and release mechanism 3 does not release the lower suction tube segment 20 onto the suction tube support mold 2 (the probability of this situation is extremely low), then the detection sensor head 431 detects (measures) the missing lower suction tube segment, and the detection sensor 43 feeds the signal back to the electrical controller 70. The aforementioned rotary table drive motor 1011 stops working, and the online operator or on-duty personnel handle the situation, for example, by manually adding a lower suction tube segment 20 to the suction tube support mold 2 that is missing the lower suction tube segment 20.

[0042] Please see Figure 5 And combined Figure 1 The aforementioned suction pipe pressing mechanism 6 (also referred to as the "suction pipe upper and lower pipe segment pressing and forming mechanism", hereinafter the same) includes a suction pipe segment pressing cylinder support 61, a support pad 62, a support top plate 63, a suction pipe upper and lower pipe segment pressing cylinder 64, a pressing mold fixing seat 65, a pressing mold 66, and a pair of pressing mold fixing seat guide pillars 67. The suction pipe segment pressing cylinder support 61 consists of a pair of longitudinally parallel longitudinal arms 611 and a longitudinal arm fixing plate 61. The system consists of two components: the lower ends of a pair of longitudinal arms 611 are fixed to both sides of a longitudinal arm fixing plate 612, which is fixed to the upward-facing side of a support pad 62. The support pad 62 is fixed to the worktable 10 with screws at positions corresponding to the screw holes 621. The end of the support top plate 63 facing the pair of longitudinal arms 611 is fixed to the top of the pair of longitudinal arms 611, while the end of the support top plate 63 facing the rotary table 1 is in a suspended state. Above the suction pipe bearing mold 2 set on the aforementioned rotary table 1, the suction pipe upper and lower pipe segment pressing cylinder 64 is set longitudinally on the upper surface of the support top plate 63 facing the rotary table 1. The lower end of the pressing cylinder column 641 of the suction pipe upper and lower pipe segment pressing cylinder 64 extends to the lower part of the support top plate 63. The pressing mold fixing seat 65 is fixed to the lower end of the aforementioned pressing cylinder column 641 at a position corresponding to the lower part of the support top plate 63. The pressing mold 66 is fixed to the downward side of the pressing mold fixing seat 65. A suction pipe upper pipe segment wing plate receiving groove 661 is opened on the downward side surface of the pressing mold 66. A pair of pressing mold fixing seat guide posts 67 are longitudinally parallel to each other. The lower ends of the pair of pressing mold fixing seat guide posts 67 are fixed to the pressing mold fixing seat 65, while the upper ends of each form a sliding pair with the guide post sliding sleeve 671, which slides up and down. The aforementioned guide post sliding sleeve 671 is fixed to the aforementioned support top plate 63.

[0043] In this embodiment, the aforementioned upper and lower suction pipe compression cylinder 64 is a cylinder.

[0044] Because the suction tube pressing mechanism 6 is located after the suction tube extraction and release mechanism 5, and from the... Figure 1The workstation shown can be called the fourth workstation. Therefore, the upper tube 30 of the suction tube is extracted and placed on the lower tube 20 of the suction tube in a face-to-face state with the lower tube 20 (the tube cavity of the lower tube 20 faces upward, while the tube cavity of the upper tube 30 faces downward), and the aforementioned lower tube tenon 202 corresponds to the upper tube mortise 302. When the suction pipe support mold 2, which carries the upper and lower suction pipe segments 30 and 20 and is initially engaged or corresponding to each other, rotates with the turntable 1 to the position corresponding to the suction pipe pressing mechanism 6, and the turntable 1 is temporarily stopped, the suction pipe upper and lower pipe segment pressing cylinder 64 operates. The pressing cylinder column 641 moves downward, pushing the pressing mold fixing seat 65, guided by a pair of pressing mold fixing seat guide columns 67, and the pressing mold 66 to move downward. The suction pipe upper pipe segment wing plate receiving groove 661 applies pressure to the suction pipe upper pipe segment wing plate 301, causing the suction pipe upper pipe segment 30 to press against the suction pipe lower pipe segment 20. In the aforementioned state, since the lower pipe segment tenon 202 and the upper pipe segment mortise 302 achieve mortise and tenon engagement, the assembly of the upper and lower suction pipe segments 30 and 20 is completed. Immediately afterwards, the aforementioned upper and lower tube pressing cylinders 64 reverse their operation, causing the pressing mold 66 to return upward, that is, away from the upper tube 30 of the air intake pipe. The finished air intake pipe 40, which has completed pressing, is rotated by the air intake pipe bearing mold 2 along with the rotary table 1 to the next station, namely the finished air intake pipe lifting mechanism 7.

[0045] Please see Figure 6 And continue to combine Figure 1The aforementioned suction pipe finished product lifting mechanism 7 includes a longitudinal fixed arm 71, a suction pipe finished product lifting cylinder 72, a lifting cylinder fixing plate 73, a lifting cylinder fixing plate lifting cylinder 74, a lifting cylinder lateral displacement fixing plate 75, a lateral displacement fixing plate sliding seat 76, and a suction pipe finished product lifting lateral movement cylinder 77.

The lower part of the suction pipe finished product lifting cylinder 72 has a suction pipe finished product lifting gripper 721. The lifting cylinder fixing plate 73 is fixed to the lifting cylinder fixing plate lifting cylinder 74's upper and lower sliding seat 741. The upper and lower sliding seat 741 of the lifting cylinder is slidably engaged with the lifting cylinder fixing plate lifting cylinder 74 and driven by the lifting cylinder fixing plate lifting cylinder 74. The lifting cylinder fixing plate lifting cylinder 74 is fixed to the lifting cylinder lateral displacement fixing plate 75. The lifting cylinder lateral displacement fixing plate 75 is fixed to the lateral displacement fixing plate sliding seat 76. The lateral displacement fixing plate sliding seat 76 is slidably engaged with the suction pipe finished product lifting lateral movement cylinder 77 and driven by the suction pipe finished product lifting lateral movement cylinder 77. The end of the suction pipe finished product lifting lateral movement cylinder 77 facing the rotary table 1 is fixed to the upper end of the aforementioned longitudinal fixing arm 71. The end of the suction pipe finished product lifting lateral movement cylinder 77 away from the rotary table 1 is configured as a horizontal cantilever end. Since the structure and working mechanism of the aforementioned retained suction pipe removal mechanism 9 are the same as the structure of the aforementioned suction pipe finished product lifting mechanism 7, the applicant will not repeat the description.

[0046] See the key points Figure 6A limiting head 7411 is fixed on the side of the lifting cylinder fixed plate lifting cylinder sliding seat 741 facing the rotary table 1. A limiting head downward limit position limiting screw seat 742 is fixed on the side of the lifting cylinder fixed plate lifting cylinder 74 facing the rotary table 1 and on the surface corresponding to the downward side of the limiting head 7411. A limiting head downward limit position limiting screw 7421 is provided on the limiting head downward limit position limiting screw seat 742. A limiting head upward limit position limiting screw seat 743 is fixed on the top of the lifting cylinder fixed plate lifting cylinder 74 and on the surface corresponding to the upward side of the limiting head 7411. A limiting head upward limit position limiting screw 7431 is provided on the limiting head upward limit position limiting screw seat 743. The length of the aforementioned transverse displacement fixed plate sliding seat 76 is... A limiting block 761 is fixed in the middle of the side facing upward. A first limiting screw seat 771 is fixed on the end face of the aforementioned suction pipe lifting lateral movement cylinder 77 facing the aforementioned rotary table 1 and located at the top. The first limiting screw seat 771 corresponds to the side of the limiting block 761 facing the rotary table 1 and is provided with a first limiting screw 7711. A second limiting screw seat 772 is fixed on the end face of the suction pipe lifting lateral movement cylinder 77 away from the rotary table 1 and located at the top. The second limiting screw seat 772 corresponds to the side of the limiting block 761 away from the rotary table 1 and is provided with a second limiting screw 7721. The aforementioned suction pipe lifting cylinder 72, lifting cylinder fixing plate lifting cylinder 74, and suction pipe lifting lateral movement cylinder 77 are cylinders.

[0047] Depend on Figure 1As can be seen from the diagram, the aforementioned suction pipe finished product lifting mechanism 7 is actually the fifth workstation. When the rotary table 1 rotates the suction pipe bearing mold 2, which carries the suction pipe finished product 40 after the upper and lower pipe segments have been pressed together, to the workstation where the suction pipe finished product lifting mechanism 7 is located in the aforementioned relay manner, and the rotary table 1 is in a paused state, the lifting action cylinder fixing plate lifting action cylinder 74 operates. The upper and lower sliding seats 741 of the lifting action cylinder fixing plate lifting action cylinder, together with the suction pipe finished product lifting action cylinder 72 fixed thereto, move downwards, and the suction pipe finished product lifting action cylinder 72 operates, with a pair of suction pipe finished product lifting grippers 721 clamping the suction pipe upper pipe segment wing plate 301. Then, the aforementioned lifting action cylinder fixing plate lifting action cylinder 74 operates in the opposite direction, causing the upper and lower sliding seats 741 of the lifting action cylinder fixing plate lifting action cylinder, together with the suction pipe finished product lifting action cylinder 72 clamping the suction pipe upper pipe segment wing plate 301, to move upwards. At this point, the entire suction pipe finished product 40 is pulled out, i.e., lifted away from the suction pipe bearing mold 2. Next, the suction pipe finished product lifting lateral movement cylinder 77 operates, causing the lateral displacement fixing plate sliding seat 76, along with the lifting cylinder lateral displacement fixing plate 75 fixed thereon, to move to the left. Figure 1 Taking the position shown as an example, the lifting cylinder lateral displacement fixing plate 75 drives the lifting cylinder fixing plate lifting cylinder 74, the lifting cylinder fixing plate lifting cylinder upper and lower sliding seat 741, the lifting cylinder fixing plate 73, and the suction pipe finished product lifting cylinder 72, which are fixed on the lifting cylinder fixing plate 75, to move to the left accordingly. This causes the suction pipe finished product 40, which is held by a pair of suction pipe finished product lifting claws 721, to be suspended above the aforementioned suction pipe finished product outlet groove 106. Then, the suction pipe finished product lifting cylinder 72 works again to cause its pair of suction pipe finished product lifting claws 721 to open, releasing the previously held suction pipe finished product 40 into the suction pipe finished product outlet groove 106, where it is discharged by the suction pipe finished product outlet groove 106 with a sliding effect.

[0048] Depend on Figure 1 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 cavity wall of the workbench cavity.

[0049] 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.

[0050] Applicant combined Figures 1 to 7 The entire working process of this utility model is systematically described. At the aforementioned work station of the suction pipe lower tube fragment extraction and release mechanism 3 (which can be referred to as the first work station), according to the applicant's description of the working process of the suction pipe lower tube fragment extraction and release mechanism 3 above, the suction pipe lower tube fragment 20 input by the suction pipe lower tube fragment input track 80a is extracted and placed into the suction pipe bearing mold 2 on the rotary table 1. Since the support state of the suction pipe lower tube fragment 20 on the suction pipe bearing mold 2 can be determined by... Figure 2 The details are not elaborated here, therefore the applicant will not repeat them. When the suction pipe support mold 2 carrying the lower suction pipe segment 20 on the rotary table 1 rotates to the position corresponding to the suction pipe segment missing detection mechanism 4, which serves as the second station, it is handled in the manner described above by the applicant. 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 suction pipe upper pipe segment extraction and release mechanism 5 will, in a manner similar to the suction pipe lower pipe segment extraction and release mechanism 3, engage the suction pipe upper pipe segment 30 input from the suction pipe upper pipe segment input track 80b with the suction pipe lower pipe segment 20 in the manner described above by the applicant. When the rotary table 1 rotates the suction pipe support mold 2, which carries the upper and lower suction pipe segments 30 and 20 in a snap-fit ​​state, to the position of the suction pipe pressing mechanism 6, which serves as the fourth station, the suction pipe pressing mechanism 6 presses the upper and lower suction pipe segments 30 and 20 together with a mortise and tenon-like fit effect to form the finished suction pipe 40, as described above by the applicant. Figure 1 (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.

[0051] 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 at the seventh station. When the suction pipe bearing mold 2 with the stagnant suction pipe finished product 40 or suction pipe lower tube 20 rotates 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 in the same way as the suction pipe finished product removal mechanism 7 described above, and it is then discharged from the stagnant suction pipe outlet groove 107. As the rotary table drive mechanism 101 continues to rotate the rotary table 1, the suction pipe support mold 2, which originally corresponded to the stuck suction pipe removal mechanism 9, is aligned with the position of the stuck suction pipe retention 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 stuck suction pipe removal mechanism 9, then the stuck suction pipe retention 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 stuck 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 units of this utility model) by operating the corresponding buttons on the electrical controller 70. After the finished intake pipe 40 is assembled by this utility model, it is discharged from the intake pipe finished product outlet groove 106 and supplied to the subsequent process for assembly with the housing of the intake muffler.

[0052] 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.
