[0042] It should be noted that the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0043] In combination Figures 1 to 21 As shown, the present disclosure provides a compressor opening retainer assembly device, which comprises a conveying device 10, a positioning device 20, a feeding device 30 and a transfer device 40. The conveying device 10 is used to convey a target compressor 52. The positioning device 20 is located on one side of the conveying device 10, and is used to position the target compressor 52 conveyed by the conveying device 10 to a first set position. The feeding device 30 is located on one side of the positioning device 20, and is used to store and drop an opening retainer 55. The transfer device 40 is located between the feeding device 30 and the positioning device 20, and is used to transfer the target opening retainer 56 dropped by the feeding device 30 to the first set position, and assemble the target opening retainer 56 to the target compressor 52.

[0044] In the embodiment of the present disclosure, the conveying device 10 conveys the target compressor 52 to the positioning device 20, and the conveying device 10 plays a role of transportation and delivery, so as to save manpower and material resources, and realize automatic circulation of the compressor, and facilitate assembly of the open blocking ring 55 in a pipeline. After the conveying device 10 conveys the target compressor 52 to the positioning device 20, the positioning device 20 can adjust or fix the position of the target compressor 52, so as to make the target compressor 52 be located at the first set position, so as to realize accurate positioning of the target compressor 52, so as to facilitate cooperation of the target compressor 52 with the transfer device 40. The feeding device 30 stores the open blocking ring 55, and can put the open blocking ring 55, and the transfer device 40 is located between the feeding device 30 and the positioning device 20, that is, the transfer device 40 can move the target open blocking ring 56 put by the feeding device 30 to the first set position corresponding to the positioning device 20, so as to facilitate assembly of the target open blocking ring 56 to the target compressor 52. The embodiment of the present disclosure integrates the feeding, positioning and assembly stations originally dispersed in the same production line through the above-mentioned various devices, and realizes full-process automatic assembly of the compressor open blocking ring 55. Compared with manual assembly, not only the assembly efficiency is improved, the manpower is saved, but also the compressor missing open blocking ring 55 can be avoided, and then the situation that the compressor falls off in the refrigerator transportation process due to missing open blocking ring 55 of the refrigerator and compressor, and the refrigerator is damaged can be avoided.

[0045] It can be understood that the compressor of the present application is not only limited to be applied to the refrigerator, but also can be applied to the refrigerator, the freezer and other refrigeration equipment or other equipment provided with the compressor.

[0046] It should be noted that the conveying device 10 can convey multiple compressors at the same time, and the compressor being assembled is defined as the target compressor 52. The feeding device 30 can be provided with multiple open blocking rings 55, and the target open blocking ring 56 refers to the open blocking ring 55 selected from the feeding device 30, that is, the open blocking ring 55 transferred by the transfer device 40 and assembled to the target compressor 52. Similarly, the target barrel in the following refers to the barrel containing the target open blocking ring 56.

[0047] Optionally, as shown in Figures 7 to 14 The feeding device 30 includes a storage device 31 and a push-pull device 32, the storage device 31 is used for storing the open blocking ring 55; the push-pull device 32 corresponds to the transfer device 40, and the push-pull device 32 and the transfer device 40 are provided with a push-out position, and the push-pull device 32 is used for putting the target open blocking ring 56 of the storage device 31 at the push-out position to the second set position, so that the transfer device 40 transfers the target open blocking ring 56 at the second set position to the first set position.

[0048] The storage device 31 of the feeding device 30 is used to store the open blocking ring 55, so that the storage device 31 can store a plurality of open blocking rings 55 at one time, so as to ensure the continuous work of the compressor open blocking ring assembly device and realize the automatic assembly of the open blocking ring 55. In addition, the feeding device 30 also has a push-pull device 32, which plays a role of putting the target open blocking ring 56 of the storage device 31, so that the transfer device 40 can obtain the target open blocking ring 56. Here, since the push-pull device 32 corresponds to the transfer device 40, the push-out position is located between the push-pull device 32 and the transfer device 40, that is, the push-out position is in the intersection area of the action range of the push-pull device 32 and the grasping preparation range of the transfer device 40. When the target cartridge in the storage device 31 moves to the push-out position under the driving of the rotating driving mechanism 33, the push-pull device 32 can operate the target open blocking ring 56 in the target cartridge. The push-pull device 32 acts at the push-out position to push the target open blocking ring 56 at the position out of the storage device 31, so that the target open blocking ring 56 enters the second set position, which can be understood as the transfer position of the transfer device 40. The transfer device 40 takes the push-out position as a reference to grasp the target open blocking ring 56, so as to ensure that the target open blocking ring 56 pushed to the second set position by the push-pull device 32 can be accurately received. Through the space and time coordination of the push-pull device 32 and the transfer device 40, the positioning problem in the blocking ring transfer process is solved.

[0049] In addition, in the embodiment of the present disclosure, the push-pull device 32 accurately pushes the target open blocking ring 56 in the storage device 31 to the second set position, so that the transfer device 40 can grasp without entering the inside of the feeding device, reducing the risk of interference between components and the operation difficulty of the transfer device 40. Through the storage device 31, the push-pull device 32 and the transfer device 40, the target open blocking ring 56 is accurately put in the position, so as to ensure the success rate of grasping of the transfer device 40 and improve the efficiency and accuracy of the assembly of the compressor open blocking ring 55.

[0050] Optionally, the push-pull device 32 can be adapted to different sizes of open blocking rings or the same size of open blocking rings.

[0051] Optionally, as Figure 7As shown, the storage device 31 includes a cartridge table 311 and cartridges 34, the cartridges 34 are arranged above the cartridge table 311, the number of cartridges 34 is multiple, and the multiple cartridges 34 are sequentially and spacedly arranged along the circumference of the cartridge table 311, and the cartridges 34 are used to store the open blocking ring 55; the feeding device 30 further includes a rotating driving mechanism 33 connected with the cartridge table 311, used to drive the cartridge table 311 and the multiple cartridges 34 to rotate synchronously; wherein, after the rotating driving mechanism 33 drives the target cartridge to move to the pushing position, the push-pull device 32 puts the target open blocking ring 56 in the target cartridge into the second set position.

[0052] In the embodiment of the present disclosure, the storage device 31 adopts the mode that the multiple cartridges 34 are sequentially and spacedly arranged along the circumference of the cartridge table 311, which increases the storage amount of the open blocking ring 55, reduces the frequency of frequently supplementing the open blocking ring, and improves the continuity of production. The rotating driving mechanism 33 drives the cartridge table 311 and the cartridges 34 to rotate, which can sequentially move the open blocking rings 55 in different cartridges 34 to the pushing position, realizes the orderly feeding of the multiple cartridges 34, and improves the flexibility and diversity of feeding. For example, when the target cartridge is empty, the rotating driving mechanism 33 drives the cartridge table 311 to rotate to switch to the full cartridge 34, which realizes zero downtime feeding. The cartridge table 311, the multiple cartridges 34 and the rotating driving mechanism 33 can realize uninterrupted feeding and rapid changeover, and further improve the production efficiency.

[0053] In some optional embodiments, the feeding device can not be provided with the rotating driving mechanism, that is, the cartridge table and the cartridge will not move, and the target cartridge is always in the pushing position, so that feeding into the target cartridge can realize discharging.

[0054] Optionally, as shown, Figures 8 to 10 The bottom of the cartridge 34 and the cartridge table 311 form a discharging gap 318, and the open blocking ring 55 in the cartridge 34 can move to the discharging gap 318 under the action of gravity; the push-pull device 32 can move between the extended position and the retracted position, when the push-pull device 32 is in the retracted position, the push-pull device 32 avoids the discharging gap 318, so that the target open blocking ring 56 falls into the discharging gap 318; when the push-pull device 32 is in the extended position, the moving end 322 of the push-pull device 32 is located in the discharging gap 318, and the moving end 322 of the push-pull device 32 can block the open blocking ring 55 in the target cartridge from falling into the discharging gap 318; wherein, in the case that the push-pull device 32 is in the extended position and the target open blocking ring 56 is arranged in the discharging gap 318, the push-pull device 32 can abut against the target open blocking ring 56, and push the target open blocking ring 56 from the discharging gap 318 to the second set position.

[0055] In the embodiment of the present disclosure, the bottom of the hopper 34 and the hopper table 311 form a discharging gap 318, and the open blocking ring 55 can automatically fall into the discharging gap 318 under the action of gravity, without the need for additional power to drive the blocking ring to move, thereby simplifying the structure and reducing energy consumption. The push-pull device 32 can move between an extended position and a retracted position, and the moving end 322 of the push-pull device 32 can move in the discharging gap 318, so that when the push-pull device 32 is retracted, the push-pull device 32 avoids the discharging gap 318, and it can be understood that the push-pull device 32 is located on one side of the discharging gap 318, so that the discharging gap 318 is not blocked, and the open blocking ring 55 in the hopper 34 can fall into the discharging gap 318 under the action of gravity. When the push-pull device 32 moves towards the extended position, the moving end 322 of the push-pull device 32 can abut against the target open blocking ring 56 that falls into the discharging gap 318, so that the push-pull device 32 can push the target open blocking ring 56 to move to the second set position, so as to facilitate the transfer device 40 to transfer the target open blocking ring 56. In this way, the push-pull device 32 can accurately control the target open blocking ring 56 to be pushed from the discharging gap 318 to the second set position, thereby realizing accurate pushing of the target open blocking ring and improving the accuracy of feeding.

[0056] Optionally, the push-pull device 32 can make linear reciprocating motion in the discharging gap 318, so as to realize automatic feeding of the open blocking ring 55 and short movement stroke and less friction of the open blocking ring 55, thereby effectively reducing the failure rate and energy consumption and improving the service life of the push rod 321.

[0057] Optionally, as shown in Figure 7 and Figure 8 , the hopper 34 extends in the vertical direction, and a plurality of open blocking rings 55 in one hopper 34 are arranged in a vertical stack, so that the open blocking ring 55 located at the bottom of the hopper 34 can quickly fall into the discharging gap 318 under the action of its own gravity and the open blocking ring 55 above it, so as to ensure the feeding speed of the open blocking ring 55.

[0058] Optionally, as shown in Figures 9 to 12 , Figure 20 and Figure 21 , the push-pull device 32 includes a push rod 321, an elastic member 328, and a hook claw 326, the push rod 321 is movably located in the discharging gap 318; the elastic member 328 is connected between the push rod 321 and the hopper table 311, and the elastic member 328 deforms elastically when the push rod 321 moves away from the extended position; the hook claw 326 is movably located on one side of the push rod 321, as shown in Figure 21 , when the push rod 321 is in the extended position, the hook claw 326 is separated from the push rod 321, and when the push rod 321 is in the retracted position, as shown in Figure 20As shown, the hook 326 is in abutment with the push rod 321; when the push rod 321 moves from the extended position to the retracted position, the hook 326 is in abutment with the push rod 321 and exerts a force on the push rod 321 to move from the extended position to the retracted position; when the push rod 321 moves from the retracted position to the extended position, the hook 326 is separated from the push rod 321, and the elastic member 328 exerts a force on the push rod 321 to move from the retracted position to the extended position.

[0059] In the embodiment of the present disclosure, the push rod 321 is used to cooperate with the target opening blocking ring 56 to move, and the elastic member 328 and the hook 326 respectively provide the push rod 321 with a force to move towards the retracted position and the extended position. The push rod 321 in the push-pull device 32 is movably arranged in the discharging gap 318 and can directly contact and push the target opening blocking ring 56 to move. The elastic member 328 is connected between the push rod 321 and the barrel table 311, and provides the push rod 321 with an elastic restoring force, so that the push rod 321 can be automatically reset under the action of the elastic member 328 after leaving the extended position, thereby reducing the use of an external driving device and simplifying the structure. The hook 326 cooperates with the push rod 321, when the push rod 321 moves from the extended position to the retracted position, the hook 326 exerts a force on the push rod 321 to assist the push rod 321 to quickly avoid the discharging gap 318; when the push rod 321 moves from the retracted position to the extended position, the hook 326 is separated from the push rod 321, and the hook 326 does not exert a force on the push rod 321, and the push rod 321 moves to the extended position under the action of the elastic member 328, thereby further improving the reliability and stability of the movement of the push rod 321.

[0060] Optionally, the push rod 321 is arranged on the barrel table 311, and the discharging gap 318 of each barrel 34 is provided with a push rod 321, and the push rod 321 can rotate with the barrel table 311 and the barrel 34; the hook 326 is always corresponding to the extended position, and the barrel table 311 can rotate relative to the hook 326 to enable the hook 326 to cooperate with the corresponding push rod 321 of any one of the plurality of barrels 34 to move.

[0061] In the embodiment of the present disclosure, the push rod 321 is arranged on the barrel table 311 and each barrel 34 is provided with a push rod 321, so that the push rod 321 can rotate synchronously with the barrel table 311 and the barrel 34, and it is ensured that each barrel 34 has a corresponding push rod 321 to cooperate with the hook 326 to complete the blocking ring pushing action when the barrel 34 is rotated to the extended position, thereby avoiding switching delay caused by a single push rod 321 corresponding to multiple barrels 34 and improving the continuity when multiple barrels 34 are fed.

[0062] In addition, the push rod 321 of each barrel 34 is provided with an elastic element 328 connected between the push rod 321 and the barrel table 311, so that the push rod 321 is mainly subjected to the force of the elastic element 328 without the action of the hook claw 326. At this time, the push rod 321 is located at the extended position, that is, the moving end of the push rod 321 is located at the discharging gap 318, so that the push rod 321 can be stopped at the bottom of the barrel 34, and the opening retainer 55 in the barrel 34 cannot fall out. When the barrel 34 does not need to discharge, the bottom of the barrel 34 is blocked by the push rod 321, which can ensure that the opening retainer 55 cannot be thrown out or fall off during the rotation of the barrel table 311.

[0063] The hook claw 326 is always corresponding to the push-out position, and the barrel table 311 can rotate relative to the hook claw 326. When the target barrel containing the target opening retainer 56 moves to the push-out position, the hook claw 326 can precisely cooperate with the push rod 321 of the target barrel. The hook claw 326 moves the push rod 321 of the target barrel to the retracted position, so that the target opening retainer 56 in the target barrel can fall into the discharging gap 318 between the target barrel and the barrel table 311. Then, the push rod 321 can be extended again to push the target opening retainer 56 to the second set position, so as to realize the discharging of the target opening retainer 56. After the target opening retainer 56 in the target barrel is completely put, the barrel table 311 rotates to move away the barrel 34 in which the target opening retainer 56 is completely put, and the next target barrel is rotated to the push-out position. The hook claw 326 moves again to continuously discharge, realizing the efficient mechanical reuse of the multi-station opening retainer 55. The hook claw 326 is always corresponding to the push-out position, so that the position of the hook claw 326 does not need to be frequently adjusted, simplifying the control logic and reducing the mechanical debugging difficulty. At the same time, the hook claw 326 can cooperate with the push rod 321 corresponding to any one of the plurality of barrels 34 to move, which greatly enhances the adaptability of the feeding device 30 to the switching of different barrels 34, so that the device can flexibly cope with the feeding demand of opening retainers 55 of different specifications and batches, further improving the automation degree and production efficiency of the entire assembly device, and reducing the downtime caused by the replacement of the barrel 34.

[0064] Optionally, as shown in Figure 12 The push-pull device 32 further comprises a push-pull driving mechanism 327 connected with the hook claw 326 and used for driving the hook claw 326 to move. The inner side of the barrel table 311 is configured with a fixed column 243, and the barrel table 311 can drive the barrel 34 to move around the fixed column 243. The push-pull driving mechanism 327 and the hook claw 326 are installed on the fixed column 243, and the hook claw 326 is always corresponding to the push-out position.

[0065] The push-pull driving mechanism 327 is connected with the hook claw 326 in the embodiment of the present disclosure, and is used to drive the hook claw 326 to move, so as to accurately control the abutment and separation of the hook claw 326 and the push rod 321, and ensure that the push rod 321 moves in a predetermined manner. The inside of the barrel table 311 is provided with a fixed column 243, the barrel table 311 drives the barrel 34 to move around the fixed column 243, and the push-pull driving mechanism 327 and the hook claw 326 are installed on the fixed column 243, so that the hook claw 326 is always corresponding to the push-out position, which ensures that the hook claw 326 can accurately cooperate with the push rod 321 during the rotation of the barrel table 311, and improves the stability and reliability of the whole device.

[0066] Optionally, the push-pull driving mechanism 327 can be a motor, a cylinder or a motor.

[0069] In the embodiment of the present disclosure, for the barrel table 311 and the barrel 34, when the transfer driving device drives the barrel table 311 to drive a plurality of barrels 34 to rotate to switch the feeding, the hook claw 326 will not hinder the rotation path thereof, ensuring that the barrel table 311 can smoothly complete the circumferential rotation, so that different barrels 34 can accurately and efficiently move to the push-out position in sequence, and the continuity and stability of the multi-barrel 34 feeding are ensured. For the push rod 321, since there is no interference in the rotation direction, the push rod 321 will not rub or jam with the hook claw 326 when the push rod 321 rotates with the barrel table 311, which not only protects the structural integrity of the push rod 321 and the hook claw 326, prolongs the service life of the components, but also ensures that the push rod 321 can accurately cooperate with the hook claw 326 to complete the blocking ring pushing action after the push rod 321 rotates with the barrel table 311 to the push-out position, further improving the operation reliability and overall assembly efficiency of the feeding device 30.

[0070] In addition, when the push rod 321 rotates with the barrel table 311, the push rod 321 is located in the extended position under the action of the elastic member 328, at this time, the hook claw 326 is separated from the push rod 321, so that the hook claw 326 and the push rod 321 will not contact, and the barrel table 311 can drive the barrel 34 and the push rod 321 to rotate without friction with the hook claw 326.

[0071] Optionally, the distance between each cartridge 34 moved to the pushing position and the push rod 321 and the hook claw 326 corresponding to the cartridge 34 is the same or very small, so that the hook claw 326 moves a preset distance to realize the cooperation of the hook claw 326 and the push rod 321. When the plurality of cartridges 34 rotates with the cartridge table 311, the interference between the hook claw 326 and the rotating cartridge 34 or the push rod 321 can be avoided.

[0072] Optionally, a circular opening is formed in the inner side of the cartridge table 311, and the axis of the fixed column 243 is located at the center of the circular opening, so that the distance between each cartridge 34 moved to the pushing position and the push rod 321 and the hook claw 326 corresponding to the cartridge 34 is within a set range, to ensure the cooperation of the push rod 321 and the hook claw 326.

The rotating disc 312 is connected with the rotating drive mechanism 33 to realize the rotation of the cartridge table 311. The cartridge seat 313 is arranged above the rotating disc 312, so that the cartridge seat 313 is raised in height to facilitate the formation of the discharging gap 318 between the bottom of the cartridge 34 and the cartridge seat 313, thereby providing a passage for the discharging of the open blocking ring 55. The cartridge seat 313 is provided with a slide 314, and the push rod 321 is slidably arranged in the slide 314. The slide 314 plays a guiding and limiting role in the movement of the push rod 321, avoiding the movement deviation and shaking of the push rod 321, so that the movement of the push rod 321 is more stable and accurate, and the pushing of the target open blocking ring 56 can be better controlled, thereby improving the accuracy and stability of the feeding.

[0075] Optionally, the push rod 321 includes a movement rod 323 and an operation rod 324.

The operating rod 324 is connected to the other end of the movement rod 323, and the upper end of the operating rod 324 is provided with a protrusion 325 corresponding to the hook claw 326 and capable of abutting or separating. That is, the movement rod 323 is responsible for cooperating with the discharging gap 318 and the opening blocking ring 55 to move, and the operating rod 324 is used for the hook claw 326 and the elastic member 328 to apply force. In this way, the cooperation between the hook claw 326 and the push rod 321 is facilitated, and the movement control of the push rod 321 is more accurate. In addition, the height of the protrusion 325 of the push rod 321 exceeds the barrel seat 313, so that the hook claw 326 does not need to enter the inside of the barrel seat 313 to apply force, which can also ensure that the hook claw 326 does not interfere with the movement of the barrel base 311 and the push rod 321.

[0077] Optionally, the lower end of the hook claw 326 is provided with a bending structure 3261, and the bending structure 3261 is located on the side of the push rod 321 facing the barrel 34.

When the hook claw 326 drives the push rod 321 to move from the extended position to the retracted position, the push-pull driving mechanism 327 first drives the hook claw 326 to move towards the push rod 321, and then abuts against the push rod 321, and then drives the push rod 321 to move away from the barrel 34.

[0078] Optionally, the bending structure 3261 corresponds to the protrusion 325 and cooperates with the protrusion 325 to move.

[0081] In the embodiments of the present disclosure, each of the same-position barrels has a corresponding movement end 322 to operate, and the synchronization of the discharging of the multiple same-position barrels is realized. The multiple movement ends 322 of the multi-end push rod move synchronously, so that the target opening block 56 in each same-position barrel can be pushed to the second set position at the same time, and when the compressor needs to install multiple opening blocks 55, the multiple opening blocks 55 can be installed synchronously, and the assembly efficiency is further improved. Here, the same-position barrel can be understood as a barrel that discharges synchronously, and the multi-end push rod can be understood as a push rod with multiple movement ends.

[0084] Optionally, when one barrel seat 311 is provided with multiple barrels 34, the multiple barrels 34 can all be same-position barrels, or part of the multiple barrels 34 are same-position barrels. For the multiple same-position barrels of one barrel seat 311, the barrel seat 311 is provided with a multi-end push rod, and the number of the multiple same-position barrels of the barrel seat 311 is the same as the number of the movement ends 322 of the multi-end push rod of the barrel seat 311 and corresponds to the movement ends 322 one by one. Alternatively, one barrel seat 311 is provided with multiple same-position barrels, and each type of same-position barrel corresponds to a multi-end push rod, that is, one barrel seat 311 can be provided with multiple multi-end push rods.

[0085] Optionally, one barrel seat 311 is provided with two same-position barrels and one multi-end push rod, the multi-end push rod includes two movement ends 322, the two movement ends 322 are movably arranged in the discharging gap 318 of the two same-position barrels and the barrel seat 311, and the two movement ends 322 can move synchronously, so that the target opening block 56 in the two same-position barrels of the barrel seat 311 can be synchronously put into the second set position, so that the transfer device 40 can synchronously transfer the two target opening blocks 56.

[0086] It can be understood that the second set position is not limited to one position, and can also be two positions or multiple positions. The positions within the transfer range of the transfer device 40 can be regarded as the second set position.

[0087] Optionally, one barrel seat 313 is provided with multiple barrels 34, the multiple barrels 34 and the barrel seat 313 form multiple discharging gaps 318, the number of the movement rods 323 is the same as the number of the multiple discharging gaps 318 and corresponds to the multiple discharging gaps 318 one by one, and the multiple movement rods 323 are connected through one operating rod 324.

[0088] In the embodiments of the present disclosure, the push rod 321 comprises a plurality of movement rods 323, and the plurality of movement rods 323 are connected with one operation rod 324, which is an optional embodiment of the multi-end push rod. By applying force to the operation rod 324, the plurality of movement rods 323 can be synchronously driven to move, thereby realizing the synchronous discharge of the plurality of barrels 34, that is, the plurality of co-located barrels.

[0089] Optionally, as shown in Figure 9 The barrel seat 313 is further provided with a first limiting protrusion 315 and a second limiting protrusion 316. The first limiting protrusion 315 is located on the side of the push rod 321 facing the second set position, and the second limiting protrusion 316 is located on the side of the push rod 321 away from the second set position. When the push rod 321 is in the extended position, the push rod 321 abuts against the first limiting protrusion 315. When the push rod 321 is in the retracted position, the push rod 321 abuts against the second limiting protrusion 316.

[0090] In the embodiments of the present disclosure, the two limiting protrusions 325 can accurately limit the movement position of the push rod 321, prevent the push rod 321 from excessive movement, and ensure the accuracy and stability of the movement of the push rod 321. When the elastic member 328 drives the push rod 321 to move towards the extended position, after the push rod 321 moves to the extended position, the first limiting protrusion 315 can limit the push rod 321 from continuing to move towards the second set position, thereby playing a role in precise positioning. In this way, the elastic requirement of the elastic member 328 can be reduced, that is, the elastic member 328 can be in a natural state or can still have a certain elastic deformation when the push rod 321 is in the extended position. For example, the elastic member 328 can continue to apply a force to the push rod 321 towards the second set position, but under the action of the first limiting protrusion 315, the push rod 321 is limited from moving towards the second set position. In this way, the requirement of the elastic member 328 can be reduced, and the range of the elastic member 328 that can be used is larger. As long as the elastic member 328 that can bring the push rod 321 in the retracted position back to the extended position belongs to the optional embodiments of the present application.

[0091] When the target barrel moves to the push-out position, the hook claw 326 abuts against the push rod 321 corresponding to the target barrel and applies a force, so that the movement end 322 of the push rod 321 avoids the discharge gap 318. When the push rod 321 abuts against the second limiting protrusion 316, it indicates that the push rod 321 has moved to the retracted position, thereby avoiding overtravel of the push rod 321.

[0092] Optionally, the elastic member 328 is connected between the push rod 321 and the barrel seat 313.

[0093] Optionally, the movement space of the push rod 321 is formed between the first limiting protrusion 315 and the second limiting protrusion 316.

[0095] Optionally, the number of the first limiting protrusions 315 is two, and the two limiting protrusions 325 are arranged in opposite intervals, so that the limiting effect on the push rod 321 can be ensured, and the connection between the elastic member 328 and the push rod 321 and the movement space of the elastic member 328 can also be ensured.

[0096] Optionally, when one barrel table 311 is provided with a plurality of barrels 34, the barrel table 311 is correspondingly provided with a plurality of slides 314, the number of the slides 314 is the same as and corresponds to the number of the barrels 34, wherein the two slides 314 are arranged at intervals, and the elastic member 328 is located between the two slides 314. Optionally, the first limiting protrusion 315 and the second limiting protrusion 316 are located between the two slides 314.

[0097] Optionally, as shown in Figure 13 the barrel seat 313 is partially recessed downward to form a discharging groove 317, the discharging groove 317 is located below the barrel 34, and the discharging groove 317 and the bottom of the barrel 34 define a discharging gap 318, so that the opening retainer 55 can be completely exposed from the barrel 34, and the target opening retainer 56 can be prevented from being interfered by the barrel 34.

[0098] Optionally, the barrel 34 is provided with a rod-shaped structure 341, the rod-shaped structure 341 penetrates through the plurality of opening retainers 55, can fix and limit the opening retainers 55, and can ensure that the opening retainers 55 cannot rotate in the barrel 34, so that the directions of the opening retainers 55 can be ensured to be consistent after each opening retainer 55 falls into the discharging gap 318, so as to facilitate cooperation with the movement end 322 of the push rod 321.

[0099] Optionally, when the push rod 321 is located at the extended position and cooperates with the target opening retainer 56, the movement end 322 of the push rod 321 is inserted into the groove of the target opening retainer 56.

[0100] Optionally, when the push rod 321 is located at the extended position, the movement end 322 of the push rod 321 does not exceed the outer edge of the barrel table 311, so that the push rod 321 can be prevented from interfering with components or articles outside the barrel table 311 when rotating.

[0101] Optionally, when the push rod 321 pushes the target opening blocking ring 56 to move to the second set position, at least part of the target opening blocking ring 56 is located outside the barrel 34, so that the target opening blocking ring 56 can be exposed from the bottom of the barrel 34 to facilitate the transfer device 40 to obtain the target opening blocking ring 56.

[0102] Optionally, when the push rod 321 pushes the target opening blocking ring 56 to move to the second set position, the outer edge of the target opening blocking ring 56 is located outside the outer edge of the barrel seat 313. Since the barrel seat 313 is located above the rotating disc 312 and the discharging gap 318 is located below the barrel seat 313, the outer edge of the target opening blocking ring 56 is located outside the outer edge of the barrel seat 313, and at least part of the target opening blocking ring 56 is located outside the barrel 34, so that there is no interference component above and below the target opening blocking ring 56, facilitating the transfer device 40 to obtain, and the obtaining mode can be clamping, suction or other obtaining modes.

[0104] Optionally, the rotating gear is connected below the rotating disc 312.

[0105] Optionally, the rotating gear can be fixedly connected with the barrel table 311 or detachably connected with the barrel table 311, such as welding, bonding or screw connection, and the mode capable of realizing synchronous rotation of the rotating gear and the barrel table 311 belongs to the optional embodiments of the present application, which is not limited herein. It can be understood that the rotating driving mechanism 33 is not limited to the foregoing rotating gear, and other driving modes capable of realizing rotation of the barrel table 311 belong to the optional embodiments of the present application.

[0106] Optionally, the compressor opening blocking ring assembly device further comprises a placing table 53, and the feeding device 30 and the transfer device 40 are located above the placing table 53.

[0107] Optionally, the feeding device 30 further comprises a support seat supported between the barrel table 311 and the placing table 53, so that there is enough space between the barrel table 311 and the placing table 53 to arrange the rotating driving mechanism 33, which can also reduce the friction resistance when the barrel table 311 rotates and improve the working efficiency.

[0108] Optionally, the support seat is supported between the rotating gear and the placing table 53, which can also reduce the friction resistance when the rotating gear rotates and improve the working efficiency.

[0109] Optionally, the fixed column 243 comprises a support seat, that is, the fixed column 243 can be fixedly connected with the placing table 53 through the rotating disc 312, and the rotating gear is installed on the fixed column 243.

[0110] Optionally, as shown in Figure 1 and Figure 2 , the number of the feeding device 30 is multiple, two feeding devices 30 in the multiple feeding devices 30 are respectively located on the two sides of the positioning device 20, and the number of the transfer device 40 is the same as that of the feeding device 30 and one-to-one correspondence. In this way, the speed and efficiency of feeding are increased, the assembly of the opening retainer 55 of the compressor can be carried out at the same time, and the overall production efficiency is improved.

[0111] For example, the compressor needs to install four opening retainers 55, the feeding device 30 is arranged on the two sides of the positioning device 20, and two same-positioned barrels are arranged on each barrel table 311. In this way, each feeding device 30 can simultaneously feed two target opening retainers 56, and the two feeding devices 30 can work synchronously. In this way, the four target opening retainers 56 of the compressor can be assembled at the same time, without assembling one by one, and the efficiency of assembling the opening retainer 55 is further improved.

[0112] Optionally, the number of the target opening retainers 56 fed by the two feeding devices 30 can also be different, or the number of the barrels 34 at the pushing position of the two feeding devices 30 can also be different. When the model of the compressor is different or the number of the opening retainers 55 to be assembled is different, the number of the synchronously fed target opening retainers 56 of each feeding device 30 can be adjusted.

[0113] Optionally, one barrel table 311 is provided with a plurality of barrel seats 313, and the number of the barrels 34 of each barrel seat 313 can be the same, for example, two same-positioned barrels can be arranged on each barrel seat 313. Alternatively, the number of the barrels 34 of each barrel seat 313 can also be different, for example, one barrel 34 is arranged on some barrel tables 311, and two or three barrels 34 are arranged on some barrel tables 311. In this way, the feeding device 30 can adapt to different types of compressors or other equipment, and the versatility and adaptability of the compressor opening retainer assembly device are improved.

[0114] Optionally, the sizes, structures and shapes of the plurality of barrels 34 can also be different, so that different models of opening retainers 55 can be placed, and the versatility and adaptability of the compressor opening retainer assembly device are also improved.

[0115] Optionally, as shown in Figure 15 , Figures 17 to 19As shown, the transfer device 40 includes a clamping device 41 for clamping the target opening retainer 56 and a turnover device 42 connected with the clamping device 41 for driving the clamping device 41 to turn over. Figures 17 to 19 As shown, the clamping device 41 clamps the target opening retainer 56 at the second set position, and the turnover device 42 drives the clamping device 41 to turn over to the side of the positioning device 20. Figure 1 and Figure 2 As shown, the clamping device 41 assembles the target opening retainer 56 to the target compressor 52 at the first set position.

[0116] In the embodiment of the present disclosure, the clamping device 41 in the transfer device 40 is used to clamp the target opening retainer 56, and the turnover device 42 is connected with the clamping device 41 and drives it to turn over. In this way, the transfer device 40 can not only clamp the target opening retainer 56, but also transfer the target opening retainer 56 by using the turnover device 42, so as to realize accurate transfer and assembly of the opening retainer 55, improve the efficiency and accuracy of assembly, and reduce the difficulty and error of manual operation.

[0117] Alternatively, when the turnover device 42 drives the clamping device 41 to turn over to the side of the feeding device 30, the clamping device 41 clamps the target opening retainer 56 at the second set position, and the turnover device 42 drives the clamping device 41 to turn over by 180° to the side of the positioning device 20, and the clamping device 41 assembles the target opening retainer 56 to the target compressor 52 at the first set position.

[0118] In the embodiment of the present disclosure, the 180° turnover can make the clamping device 41 form a symmetrical space conversion between the material taking position (the second set position) and the assembly position (the first set position), so as to ensure that the target opening retainer 56 does not interfere with other parts of the device during the transfer process, and optimize the space utilization efficiency of the device. In addition, the fixed 180° turnover angle can be strictly controlled by mechanical limiting or angle sensor, so that the clamping device 41 can accurately reach the preset assembly position on the side of the positioning device 20 each time, avoiding the misalignment of the retainer caused by the deviation of the turnover angle, and improving the alignment accuracy of the target opening retainer 56 and the target compressor 52 to be assembled.

[0119] Alternatively, the clamping device 41 includes a clamping finger mechanism 411 for clamping and releasing the target opening retainer 56 and a clamping driving mechanism 412 connected with the clamping finger mechanism 411 for driving the clamping finger mechanism 411 to clamp or release, wherein the number of the clamping finger mechanisms 411 is the same as and corresponds to the number of the material cylinders 34 at the pushing position.

[0120] In the embodiment of the present disclosure, the clamping device 41, the clamping finger mechanism 411 is responsible for clamping and releasing the target opening retainer 56, and the clamping driving mechanism 412 provides power for the clamping finger mechanism 411, ensures the accurate and controllable clamping finger action, can stably grab the target opening retainer 56 and reliably release it at the first set position, and reduces the risk of retainer falling off during transfer.

[0121] The number of clamping finger mechanisms 411 is the same as the number of push-out position barrels 34 and one-to-one correspondence, so that multiple clamping finger mechanisms 411 can cooperate with multiple target opening retainers 56 thrown by multiple barrels 34 at the push-out position (that is, the same position barrel), so as to realize the synchronous grabbing of multiple groups of target opening retainers 56. When multiple barrels 34 at the push-out position supply target opening retainers 56 at the same time, a corresponding number of clamping finger mechanisms 411 can act at the same time, and the clamping of multiple retainers can be completed at one time, greatly improving the efficiency of the feeding link. At the same time, the one-to-one correspondence avoids the misalignment of the clamping finger mechanism 411 and the barrel 34, ensures that each clamping finger mechanism 411 can accurately align the retainer pushed out by the corresponding barrel 34, reduces the clamping deviation, and is convenient for subsequent synchronous assembly to the target compressor 52, further improving the continuity and accuracy of the overall assembly process.

[0122] Optionally, the transfer device 40 further comprises a sliding device 43 connected between the clamping device 41 and the turnover device 42, and the sliding device 43 can drive the clamping device 41 to extend and retract to adjust the clamping position of the clamping device 41.

[0123] In the embodiment of the present disclosure, the clamping device 41 may interfere with other components in other directions during the turnover process, therefore, by setting the sliding device 43, the extension length of the clamping device 41 can be adjusted, and when moving to the first set position and the second set position, the clamping device 41 can extend or fine-tune the distance to ensure that the clamping device 41 can accurately clamp the target opening retainer 56 and accurately install the target opening retainer 56 to the compressor. When the target opening retainer 56 is in the turnover process, the sliding device 43 can drive the clamping device 41 to shorten, so as to reduce the turning radius of the clamping device 41, and further avoid the interference between the clamping device 41 and other components.

[0124] In addition, in actual production, different models of target opening retainers 56 or target compressors 52 may have size differences, resulting in deviations in the retainer placement position at the second set position or the assembly position at the first set position. The sliding device 43 adjusts the extension and retraction distance of the clamping device 41, so that the clamping finger mechanism 411 can accurately align the target opening retainer 56 at different positions, ensuring that the target opening retainer 56 can be stably clamped in the grabbing link, and avoiding grabbing failure or falling off of the target opening retainer 56 due to position deviation.
