[0002] At present, compressors are used in refrigeration systems. Intake pipes and exhaust pipes are formed on the outer shell of the compressor. Before the compressor products leave the factory, the intake pipes and exhaust pipes need to be covered with rubber plugs respectively to prevent dust or debris from entering the compressor. Currently, a three-axis mechanism is used to drive the vacuum suction cup to hold the rubber plug conveyed by the vibration plate and move it to the top of the intake pipe, and then press the rubber plug into the pipe mouth of the intake pipe.

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings.

[0020] The compressor rubber plug pressing mechanism of the utility model is as follows Figure 1 and Figure 2As shown, it includes a transverse linear module 1, a longitudinal linear module 2 and a vertical linear module 3. The longitudinal linear module 2 drives the vertical linear module 3 to move forward and backward, and the transverse linear module 1 drives the longitudinal linear module 2 and the vertical linear module 3 to move left and right. The linear module belongs to the product of the prior art. More specifically, the transverse linear module 1 includes a first slider 11 and a first guide rail 12. The first guide rail 12 is installed on the bracket 5. The first slider 11 is slidably connected to the first guide rail 12. The servo motor of the transverse linear module 1 drives the first slider 11 to move linearly through a ball screw pair; a transverse seat 20 is installed on the first slider 11, and the longitudinal linear module 2 includes a second slider 21 and a second guide rail 22. The second guide rail 22 is installed on the transverse seat 20, and the longitudinal seat 30 is installed on the second slider 21. Figure 3 As shown, the vertical linear module 3 includes a third slider 31 and a third guide rail 32 , and the third guide rail 32 is installed on the longitudinal displacement seat 30 .

[0021] like Figures 1 to 3 As shown, the compressor plug pressing mechanism of the present invention also includes a vertical shift seat 40 and a manipulator assembly 4. The vertical shift linear module 3 drives the vertical shift seat 40 to move up and down, that is, the vertical shift seat 40 is installed on the third slider 31. Figure 3 and Figure 4 As shown, the manipulator assembly 4 includes a floating connector 43, a lifting seat 44, a suction cup lifting cylinder 45, a suction cup seat 451 and a vacuum suction cup 452 for sucking the rubber plug 98. The vacuum suction cup 452 is installed on the suction cup seat 451. Specifically, a clamping hole is formed at one end of the suction cup seat 451, and the clamping hole is connected to a notch groove. The two sides of the notch groove are connected by corresponding screws. The upper part of the vacuum suction cup 452 is adapted to be arranged in the above-mentioned clamping hole, and the vacuum suction cup 452 is clamped by the above-mentioned screws. The suction cup seat 451 is installed on the piston rod of the suction cup lifting cylinder 45. The suction cup lifting cylinder 45 can be a three-rod cylinder. The cylinder body of the suction cup lifting cylinder 45 is installed on the lifting seat 44. The floating connector 43 is arranged on the upper side of the lifting seat 44. The lifting seat 44 is connected to the vertical displacement seat 40 through the floating connector 43, so that the lifting seat 44 and the vertical displacement seat 40 can move relatively to each other in a small range. The floating connector 43 can refer to the "floating connector" of the Chinese utility model patent publication number CN213460311U or the "a floating connector capable of automatic reset" of the Chinese utility model patent publication number CN104183978B or the "floating connection device and a packaging body containing a floating connection device" of the Chinese invention patent publication number CN107816476B. Figure 3 and Figure 4As shown, the manipulator assembly 4 also includes a positioning cylinder 42 and a positioning member 421 for relatively horizontally positioning the lifting seat 44 and the vertical displacement seat 40. The positioning cylinder 42 drives the connecting positioning member 421; for example, the positioning member 421 can be a polygonal rod. The positioning cylinder 42 drives the positioning member 421 in the up and down directions to fit through the vertical displacement seat 40 and the lifting seat 44, so that the lifting seat 44 and the vertical displacement seat 40 can be relatively horizontally positioned. That is, the lifting seat 44 cannot move or rotate in the horizontal plane relative to the vertical displacement seat 40. The swinging of the lifting seat 44 relative to the vertical displacement seat 40 will also cause relative displacement of part of the lifting seat 44 and the vertical displacement seat 40 in the horizontal plane. Therefore, the above-mentioned “relative horizontal positioning” also includes that the lifting seat 44 cannot swing relative to the vertical displacement seat 40. When the positioning cylinder 42 drives the positioning member 421 to separate from the lifting seat 44, the lifting seat 44 and the vertical displacement seat 40 can resume relative floating. Moreover, each time the lifting seat 44 and the vertical displacement seat 40 resume relative horizontal positioning, the horizontal relative position of the lifting seat 44 and the vertical displacement seat 40 can be reset.

[0022] like Figure 1 As shown, the vibration plate combines with the linear vibrator to arrange the rubber plug 98 and transport it to the rubber plug feeding positioner 97, the transverse linear module 1, the longitudinal linear module 2 and the vertical linear module 3 move the vacuum suction cup 452 to the top of the rubber plug 98 located at the rubber plug feeding positioner 97, the suction cup lifting cylinder 45 drives the vacuum suction cup 452 to descend, so that the vacuum suction cup 452 is close to the upper end of the rubber plug 98, the vacuum suction cup 452 holds the rubber plug 98, the suction cup lifting cylinder 45 drives the vacuum suction cup 452 to rise, the compressor 99 is placed on the conveying tray 990, and the compression The lower end of the compressor 99 is plugged and positioned with the conveying tray 990. The transverse linear module 1, the longitudinal linear module 2 and the vertical linear module 3 move in combination to move the vacuum suction cup 452 to the top of the suction pipe 991 at the upper end of the compressor 99. The positioning cylinder 42 drives the positioning member 421 to release the relative positioning effect on the lifting seat 44 and the vertical displacement seat 40, so that the lifting seat 44 and the vertical displacement seat 40 can move relatively to each other in a small range. The suction cup lifting cylinder 45 drives the vacuum suction cup 452 to descend, so that the rubber plug 98 is inserted into the suction pipe 991, and then the vacuum suction cup 452 releases the rubber plug 98. In the process of the rubber plug 98 being inserted into the suction pipe 991, as shown in FIG. Figure 7As shown, since the lower end of the rubber plug 98 is an inverted cone, the lower end of the rubber plug 98 can guide the rubber plug 98 to slide into the suction pipe 991, and since the lifting seat 44 and the vertical displacement seat 40 are in a floating connection, the lifting seat 44 and the vacuum suction cup 452 can move slightly relative to the vertical displacement seat 40, that is, the rubber plug 98 can be slightly horizontally displaced or swung so that the rubber plug 98 can slide flexibly into the suction pipe 991, thereby avoiding the failure of the rubber plug 98 to be inserted into the suction pipe 991, and also avoiding the damage of the rubber plug 98 due to forced pressing into the suction pipe 991, which is conducive to stable production. When the manipulator assembly 4 is separated from the rubber plug 98 on the suction pipe 991, the positioning cylinder 42 drives the positioning member 421 to restore the relative positioning effect on the lifting seat 44 and the vertical displacement seat 40, so that the vacuum suction cup 452 can accurately reach the position of the rubber plug feeding positioner 97 every time, avoiding the failure of sucking the rubber plug 98.

[0023] Furthermore, if Figure 5 As shown, the floating connector 43 includes a positioning connector 431, a shaft 432, an elastic gasket 433 and a basin seat 434. The axis of the shaft 432 is extended in the up-down direction. A flange 4321 is formed on the shaft 432. The elastic gasket 433 can be made of silicone rubber. The two elastic gaskets 433 are respectively attached to the upper and lower sides of the flange 4321. The elastic gasket 433 is adapted to be fitted on the shaft 432. The elastic gasket 433 is arranged in the basin seat 434. The basin seat 434 is formed with a basin bottom 4341. The basin bottom 4341 is attached to the lower side of the corresponding (lower) elastic gasket 433. The lower end of the shaft 432 protrudes downward from the basin bottom 4341. The lower end of 32 is relatively fixedly connected with the lifting seat 44 by corresponding screws, and the vertical shift seat 40 is formed with a vertical shift seat bottom plate 401, and the vertical shift seat bottom plate 401 is relatively fixedly covered and arranged on the upper end of the basin seat 434, that is, the vertical shift seat bottom plate 401 is installed and connected with the basin seat 434 by corresponding screws, and the shaft member 432 is arranged through the vertical shift seat bottom plate 401, and the upper end of the shaft member 432 is relatively fixedly connected with the positioning connecting member 431 by corresponding screws, and the cylinder body of the positioning cylinder 42 is installed on the vertical shift seat 40, and the positioning cylinder 42 is provided with a positioning clamping finger 4201, that is, the positioning cylinder 42 uses a finger cylinder, and the positioning members 421 are respectively installed on the corresponding positioning clamping fingers 4201 (it should be noted that Figure 5 The middle positioning member 421 and the positioning clamp finger 4201 are shown in exploded form. In other words, the number of the positioning members 421 is two, and the two positioning members 421 are arranged facing each other. Figure 6As shown, positioning grooves are formed at both ends of the positioning connection member 431, and the positioning cylinder 42 drives the positioning member 421 to be inserted into the corresponding positioning groove. Specifically, the positioning connection member 431 is located between the two positioning members 421. When the positioning cylinder 42 drives the positioning clamping fingers 4201 to move toward each other, the two positioning members 421 can be synchronously inserted into the positioning grooves. The cross-section of the positioning grooves can be arc-shaped or square-shaped, so the movement, rotation and swing of the positioning connection member 431 relative to the positioning cylinder 42 in the horizontal plane will be directly blocked by the positioning member 421. Since the positioning connection member 431 and the vacuum suction cup 452 are relatively horizontally positioned, the vertical movement seat 40 and the vacuum suction cup 452 can be relatively horizontally positioned; the above-mentioned positioning structure is simple and reliable. When the positioning clamp finger 4201 opens to allow the positioning member 421 to release the positioning connector 431, the flange 4321 on the shaft member 432 swings to partially elastically compress and deform the elastic gasket 433. When the shaft member 432 translates in the horizontal plane, the shaft member 432 can radially push the elastic gasket 433, and the shaft member 432 can also rotate horizontally by a small amplitude. Therefore, the structure of the floating connector 43 is conducive to the lifting seat 44 having better floating performance relative to the vertical displacement seat 40. When the shaft member 432 moves upward, the elastic gasket 433 located at the upper position can be elastically flattened and deformed accordingly. Since the basin bottom 4341 is attached to the lower side of the corresponding elastic gasket 433, the shaft member 432 is prevented from falling off the basin bottom 4341 downward.

[0024] Furthermore, the positioning groove is set as a V-shaped groove 4311, and a triangular bar 3211 for adapting to the positioning groove is formed on one side of the positioning member 421. Therefore, in the process of inserting the triangular bar 3211 into the corresponding V-shaped groove 4311, if the V-shaped groove 4311 and the triangular bar 3211 are misaligned, since the V-shaped groove 4311 has a structure that gradually narrows from the outside to the inside, the V-shaped groove 4311 can relatively guide the positioning member 421 to align the V-shaped groove 4311. When the triangular bar 3211 is inserted into the bottom of the V-shaped groove 4311, the positioning connector 431 and the lifting seat 44 can be relatively horizontally positioned. Since the positioning clamping fingers 4201 of the positioning cylinder 42 can move toward each other synchronously, that is, the positioning clamping fingers 4201 are avoided from being offset, the positioning connector 431 is restored to its initial positioning position (in the horizontal plane) each time the positioning clamping fingers 4201 clamp the positioning connector 431.

[0025] Furthermore, if Figure 3 and Figure 4 As shown, the manipulator assembly 4 also includes a push pin lifting cylinder 46 and a push pin 461 for inserting into the central blind hole 981 of the rubber plug 98 to push the lower part of the rubber plug 98 into the suction pipe 991 of the compressor 99. The push pin 461 coaxially passes through the vacuum suction cup 452, and the suction hole of the vacuum suction cup 452 is offset to one side of the push pin 461. Figure 7The central blind hole 981 is shown, and the push pin lifting cylinder 46 drives the push pin 461 to move up and down. The push pin 461 is coaxially installed on the lower end of the piston rod of the push pin lifting cylinder 46 through a rigid coupling. The cylinder body of the push pin lifting cylinder 46 is installed on the lifting seat 44, so that the push pin 461 can also float relative to the vertical displacement seat 40; through the above arrangement, in the process of pressing the rubber plug 98 into the suction pipe 991, the suction cup lifting cylinder 45 first lowers the vacuum suction cup 452, so that the lower end of the rubber plug 98 is slightly inserted into the suction pipe 991, and then the piston rod of the push pin lifting cylinder 46 drives the push pin 461 to move down and insert it into the central blind hole 981. The lower end of the push pin 461 presses against the bottom of the center blind hole 981 to further press the plug 98 into the suction pipe 991, and finally the flange at the upper end of the plug 98 is blocked by the upper end surface of the suction pipe 991. Since the push pin 461 and the center blind hole 981 are relatively radially blocked, the plug 98 is prevented from bouncing off during the process of pressing the plug 98 into the suction pipe 991. In addition, since the plug 98 and the vacuum suction cup 452 are prone to air leakage when they swing relative to each other, the push pin 461 is provided to prevent the vacuum suction cup 452 from unstablely holding the plug 98, which may lead to failure in installation of the plug 98, thereby further facilitating stable production.

[0026] Furthermore, if Figure 3 and Figure 4 As shown, the manipulator assembly 4 also includes a pipe-supporting cylinder 47 and a claw 471 for clamping the suction pipe 991 of the compressor 99. The pipe-supporting cylinder 47 drives the connecting claw 471. In other words, the pipe-supporting cylinder 47 uses a finger cylinder, and the cylinder body of the pipe-supporting cylinder 47 is relatively fixedly connected to the lifting seat 44. Specifically, the lower end of the push-pin lifting cylinder 46 is installed with a mounting plate 462 through corresponding screws, and the upper end of the pipe-supporting cylinder 47 is installed on the lower side of the mounting plate 462 through corresponding screws. The claw 471 is specifically installed on the two fingers of the pipe-supporting cylinder 47; therefore, through the above arrangement, when the lateral linear module 1 and the longitudinal linear module 46 are moved, the lateral linear module 1 and the longitudinal linear module 46 are moved. The combined movement of the module 2 and the vertical linear module 3 moves the manipulator assembly 4 to the station for installing the rubber plug 98. The pipe supporting cylinder 47 first drives the supporting claws 471 to clamp the suction pipe 991. Since the two supporting claws 471 can move toward each other synchronously, the supporting claws 471 can straighten and position the suction pipe 991 during the process of clamping the suction pipe 991 (making the upper part of the compressor 99 move slightly), and then the suction cup lifting cylinder 45 lowers the rubber plug 98, and then the push pin lifting cylinder 46 moves the push pin 461 downward. Since the suction pipe 991 is straightened and positioned in advance, it is more convenient for the rubber plug 98 to be accurately inserted into the suction pipe 991, which is conducive to stable production.

[0027] For the exhaust pipe of the compressor 99, a set of compressor rubber plug pressing mechanism of the utility model can be additionally provided on the production line to press the corresponding rubber plug into the exhaust pipe.
