[0079] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0080] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0081] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0082] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0083] Combine the following Figures 1 to 6 , describing an embodiment of the present invention.

[0084] like Figures 1 to 3 As shown, according to an embodiment of the present invention, on the one hand, an assembly fixture is disclosed for assembling sound insulation cotton on the periphery of a compressor 100, the assembly fixture comprising a base 1, a clamping assembly 2 and a positioning assembly 3, wherein the clamping assembly 2 is arranged on the base 1, the clamping assembly 2 is used to clamp the sound insulation cotton, the positioning assembly 3 is arranged on the base 1, the positioning assembly 3 and the clamping assembly 2 are staggered along the circumference of the base 1, and the positioning assembly 3 is used to fix the sound insulation cotton.

[0085] The assembly fixture of the present application is provided with a clamping component 2 and a positioning component 3, and the two are staggered to avoid mutual interference. When the sound insulation cotton is assembled, the sound insulation cotton is clamped and fixed by the clamping component 2, and the sound insulation cotton is further fixed by the positioning component 3, thereby achieving fixation and positioning of the sound insulation cotton during assembly, avoiding displacement of the sound insulation cotton during assembly, thereby ensuring assembly accuracy and further ensuring the assembly quality of the sound insulation cotton.

[0086] It is understandable that the compressor 100 is usually cylindrical, so the sound insulation cotton is configured as a cylindrical sleeve, which can be assembled by being sleeved on the outer periphery of the compressor 100.

[0087] In some embodiments, a plurality of clamping assemblies 2 are provided and the plurality of clamping assemblies 2 are arranged along the circumference of the base 1 , and the plurality of clamping assemblies 2 are located on the same circumference to clamp the sound insulation cotton at different circumferential positions.

[0088] By providing a plurality of clamping assemblies 2 and arranging them along the circumference of the base 1, the plurality of clamping assemblies 2 located on the same circumference can clamp and fix the sound insulation cotton at different circumferential positions, thereby enhancing the clamping stability of the sound insulation cotton.

[0089] Since the sound insulation cotton is in the form of a cylindrical sleeve, a plurality of clamping components 2 located on the same circumference are distributed along the outer circumference of the sound insulation cotton and are clamped and fixed.

[0090] In some embodiments, the clamping assembly 2 is movably disposed on the base 1, and the moving direction of the clamping assembly 2 is consistent with the radial direction of the sound insulation cotton.

[0091] The clamping component 2 is configured to be movable, and the moving direction is consistent with the radial direction of the sound insulation cotton. When sound insulation cotton of different diameters needs to be assembled, the sound insulation cotton of different diameters can be clamped and fixed by moving the clamping component 2, thereby enhancing the applicability of the assembly fixture.

[0092] Specifically, when the diameter of the sound insulation cotton increases, the clamping assembly 2 is moved away from the sound insulation cotton to adjust, so as to clamp and fix the large-sized sound insulation cotton. When the diameter of the sound insulation cotton decreases, the clamping assembly 2 is moved toward the sound insulation cotton to adjust, so as to clamp and fix the small-sized sound insulation cotton.

[0093] In this embodiment, multiple clamping components 2 are located on the same circle. When the multiple clamping components 2 move synchronously so that the diameter of the circle surrounded by the multiple clamping components 2 becomes smaller, the small diameter sound insulation cotton can be clamped and fixed. When the multiple clamping components 2 move synchronously so that the diameter of the circle surrounded by the multiple clamping components 2 becomes larger, the large diameter sound insulation cotton can be clamped and fixed.

[0094] Exemplarily, the number of clamping assemblies 2 can be set to three, and the three clamping assemblies 2 are distributed on the same circumference, that is, the circumferential angle between any two clamping assemblies 2 is 120°, so that the sound insulation cotton is clamped evenly at all locations around the circumference, but it is not limited to this. For example, the number of clamping assemblies 2 can be set to four, five or more.

[0095] like Figure 1 and Figure 2 As shown, in some embodiments, the assembly fixture further includes a driving component 4 , which is disposed on the base 1 , and the driving component 4 is transmission-connected to the clamping component 2 .

[0096] By providing the driving component 4 and utilizing the driving component 4 to drive the clamping component 2 to move, high-precision and automated adjustment of the clamping component 2 can be achieved, thereby ensuring adjustment efficiency and accuracy.

[0097] In terms of specific structure, in some embodiments, the driving assembly 4 includes a driving motor 41 and a transmission mechanism, wherein the driving motor 41 is disposed on the base 1, the transmission mechanism is disposed on the base 1, and the transmission mechanism is transmission-connected to both the driving motor 41 and the clamping assembly 2.

[0098] The driving motor 41 drives the transmission mechanism to move, and the movement of the transmission mechanism drives the clamping assembly 2 to move along the radial direction of the sound insulation cotton, thereby clamping and fixing the sound insulation cotton of different diameters.

[0099] In some embodiments, the transmission mechanism includes a driving gear 42, a driven gear 43 and a connecting rod 44, wherein the driving gear 42 is fixedly connected to the output shaft of the driving motor 41, the driven gear 43 is rotatably arranged on the base 1, the driven gear 43 is meshed with the driving gear 42, one end of the connecting rod 44 is hinged to the driven gear 43, and the other end of the connecting rod 44 is hinged to the clamping assembly 2, and the connecting rod 44 is driven to swing by the rotation of the driven gear 43, thereby driving the clamping assembly 2 to move.

[0100] The driving motor 41 drives the driving gear 42 to rotate, thereby driving the driven gear 43 meshing with the driving gear 42 to rotate. The rotation of the gear drives the connecting rod 44 to swing, thereby pulling or pushing the clamping assembly 2 at the other end of the connecting rod 44 to move along the radial direction of the sound insulation cotton.

[0101] Exemplarily, the driving motor 41 is fixed on the base 1, and the driving gear 42 and the motor shaft of the driving motor 41 are key-connected and fixed to realize synchronous rotation of the driving gear 42 and the motor shaft. The driven gear 43 is rotatably arranged on the base 1 through the gear shaft, and the diameter of the driven gear 43 is larger than the diameter of the driving gear 42 to realize the reduction transmission from the driving gear 42 to the driven gear 43, reduce the rotation speed of the driven gear 43, and then reduce the movement of the clamping assembly 2 to ensure its smooth movement.

[0102] The two ends of the connecting rod 44 are respectively hinged to the driven gear 43 and the clamping assembly 2. During the swinging process of the connecting rod 44, the connecting rod 44 adaptively rotates through the hinge.

[0103] Optionally, the driving motor 41 is configured as a forward and reverse motor.

[0104] By driving the motor 41 to rotate forward or reverse, the driving gear 42 is driven to rotate forward or reverse, thereby driving the driven gear 43 to rotate forward or reverse, thereby driving the connecting rod 44 to swing back and forth, and then driving the clamping assembly 2 to move back and forth, thereby clamping and fixing the sound insulation cotton of different diameters.

[0105] Preferably, a plurality of connecting rods 44 are provided, and the plurality of connecting rods 44 and the plurality of clamping assemblies 2 are provided one-to-one, and the plurality of connecting rods 44 are all connected to the driven gear 43. When the driven gear 43 rotates, the plurality of connecting rods 44 are driven to swing synchronously, and then the plurality of clamping assemblies 2 are driven to move synchronously, so as to achieve synchronous adjustment of the positions of the plurality of clamping assemblies 2, and ensure the consistency and accuracy of the adjustment.

[0106] like Figure 1 and Figure 2 As shown, in some embodiments, the assembly fixture further includes a guide structure 5 disposed on the base 1 , the guide structure 5 extends along the moving direction of the clamping assembly 2 , and the clamping assembly 2 is movably disposed on the base 1 through the guide structure 5 .

[0107] The guide structure 5 can limit and guide the movement of the clamping assembly 2 to ensure the moving path of the clamping assembly 2 so that it moves along the radial direction of the sound insulation cotton.

[0108] In some embodiments, the guide structure 5 includes a guide rail 51 and a slide seat 52, wherein the guide rail 51 extends along the moving direction of the clamping assembly 2, two guide rails 51 are provided and are arranged parallel to the base 1, and the two sides of the slide seat 52 are respectively slidably connected to the two guide rails 51, and the slide seat 52 is connected to the clamping assembly 2.

[0109] Two horizontally arranged guide rails 51 can provide stable support for both sides of the slide 52 to ensure the smooth sliding of the slide 52 along the guide rails 51, and the slide 52 is restricted between the two guide rails 51, and then the sliding direction of the slide 52 is limited and guided by the two guide rails 51, and the clamping assembly 2 and the slide 52 are connected, thereby realizing the movement guiding and limiting of the clamping assembly 2.

[0110] In this embodiment, a plurality of guide structures 5 are provided, and the plurality of guide structures 5 and the plurality of clamping assemblies 2 are provided in one-to-one correspondence, so that the plurality of clamping assemblies 2 are guided and supported one by one by the plurality of guide structures 5 .

[0111] In some embodiments, the assembly fixture further includes a position detection component 6, which is used to detect a first position and a second position of the clamping component 2, between which the clamping component 2 moves.

[0112] By providing the position detection component 6, when the clamping component 2 moves to the first position or the second position, the detection component can detect it in time, so that the moving range of the clamping component 2 can be controlled.

[0113] It can be understood that the first position and the second position are the limit positions of the movement of the clamping assembly 2, which restricts the clamping assembly 2 to move only between the first position and the second position.

[0114] In some embodiments, the position detection component 6 includes a position detection switch 61, a first detection part 62 and a second detection part 63, wherein the detection switch and the clamping component 2 move synchronously, the first detection part 62 is connected to the base 1, and based on the clamping component 2 moving to the first position, the position detection switch 61 and the first detection part 62 correspond, the second detection part 63 is connected to the base 1, and based on the clamping component 2 moving to the second position, the position detection switch 61 and the second detection part 63 correspond.

[0115] When the clamping assembly 2 moves, the detection switch is driven to move synchronously. When the clamping assembly 2 moves to the first position, the position detection switch 61 moves exactly to correspond to the first detection part 62. When the clamping assembly 2 moves to the second position, the position detection switch 61 moves exactly to correspond to the second detection part 63, thereby controlling the movement range of the clamping assembly 2 between the first position and the second position.

[0116] It should be noted that when the clamping component 2 moves to the first position, the diameter of the corresponding sound insulation cotton is the smallest, and the sound insulation cotton with the smallest diameter can be clamped and fixed. When the clamping component 2 moves to the second position, the diameter of the corresponding sound insulation cotton is the largest, and the clamping component 2 can clamp and fix the sound insulation cotton with the largest diameter. Therefore, by limiting the moving range of the clamping component 2, it is limited to clamp and fix the sound insulation cotton within the corresponding diameter range.

[0117] In some embodiments, the assembly fixture further includes an origin detection component 7, which is used to detect the origin position of the clamping component 2, and the origin position is between the first position and the second position.

[0118] An origin detection component 7 is further provided, and the origin detection component 7 can detect the origin position of the clamping component 2, so as to facilitate resetting the clamping component 2 to the origin.

[0119] In some embodiments, the origin detection component 7 includes an origin detection switch 71 and an origin detection unit 72. The origin detection switch 71 and the clamping component 2 move synchronously. The origin detection unit 72 is connected to the base 1. Based on the clamping component 2 moving to the origin position, the origin detection switch 71 and the origin detection unit 72 correspond.

[0120] When the clamping assembly 2 moves, the origin detection switch 71 is driven to move synchronously. When the clamping assembly 2 moves to the origin position, the origin detection switch 71 moves to correspond to the origin detection part 72, thereby realizing the detection of the origin position of the clamping assembly 2.

[0121] Exemplarily, both the position detection switch 61 and the origin detection switch 71 may be photoelectric sensors, but are not limited thereto.

[0122] The first detection unit 62 , the second detection unit 63 and the origin detection unit 72 are all detection components used in conjunction with the photoelectric sensor.

[0123] It should be noted that the origin position in this embodiment is between the first position and the second position means that the origin position is in the middle of the moving distance of the clamping assembly 2. For example, in some embodiments, when the installation position is sufficient, the position detection assembly 6 and the origin detection assembly 7 are both arranged in the same clamping assembly 2. In some embodiments, due to the limited installation position, the position detection assembly 6 and the origin detection assembly 7 can also be arranged in different clamping assemblies 2 respectively.

[0124] In this embodiment, the position detection switch 61 and the origin detection switch 71 are respectively arranged on the two slides 52, the first detection part 62 and the second detection part 63 are arranged on the guide rail 51 corresponding to the position detection switch 61, and the origin detection part 72 is arranged on the guide rail 51 corresponding to the origin detection switch 71.

[0125] like Figure 1 and Figure 2 As shown, with regard to the specific structure of the clamping assembly 2, in some embodiments, the clamping assembly 2 includes a clamping cylinder 21, a first clamping portion 22 and a second clamping portion 23, wherein the clamping cylinder 21 is disposed on the base 1, and the first clamping portion 22 and the second clamping portion 23 are both transmission-connected to the clamping cylinder 21, and the clamping cylinder 21 can drive the first clamping portion 22 and the second clamping portion 23 to move toward or in the opposite direction.

[0126] By driving the first clamping part 22 and the second clamping part 23 to move toward each other through the clamping cylinder 21, the first clamping part 22 and the second clamping part 23 can be clamped on the inner and outer walls of the sound insulation cotton respectively to achieve the clamping and fixing of the sound insulation cotton. By driving the first clamping part 22 and the second clamping part 23 to move in the opposite directions through the clamping cylinder 21, the first clamping part 22 and the second clamping part 23 can be separated to loosen the sound insulation cotton.

[0127] Specifically, the clamping cylinder 21 is fixedly disposed below the slide seat 52 , and the first clamping portion 22 and the second clamping portion 23 are relatively disposed below the clamping cylinder 21 .

[0128] In some embodiments, the first clamping portion 22 extends along the length direction of the sound insulation cotton, and the first clamping portion 22 is used to clamp the outer wall of the sound insulation cotton.

[0129] The first clamping portion 22 extends along the length direction of the sound insulation cotton to increase the clamping area of ​​the first clamping portion 22 on the outer wall of the sound insulation cotton. The first clamping portion 22 does not affect the assembly of the sound insulation cotton on the outer wall of the sound insulation cotton.

[0130] In some embodiments, the first clamping portion 22 is an arc-shaped clamping plate.

[0131] The first clamping portion 22 is configured as an arc-shaped clamping plate, which can adapt to the curvature of the outer wall of the sound insulation cotton, so that it fits more closely to the outer wall of the sound insulation cotton, thereby increasing the clamping matching area and enhancing the clamping stability.

[0132] Specifically, the side of the arc-shaped clamping plate facing the sound insulation cotton is formed into an arc-shaped clamping surface, and the arc-shaped clamping surface can be fitted with the outer wall of the sound insulation cotton.

[0133] In some embodiments, the length of the second clamping portion 23 is smaller than the length of the first clamping portion 22, and the second clamping portion 23 is used to clamp the inner wall of the sound insulation cotton.

[0134] The second clamping portion 23 is used to clamp the inner wall of the sound insulation cotton. Therefore, the length of the second clamping portion 23 is set to be smaller than the length of the first clamping portion 22, which can reduce the interference of the second clamping portion 23 on the assembly of the sound insulation cotton.

[0135] Since the sound insulation cotton sleeve is installed on the outer periphery of the compressor 100, the second clamping portion 23 will interfere with the compressor 100. Therefore, the second clamping portion 23 is designed to be as small as possible while ensuring the clamping and fixing of the sound insulation cotton.

[0136] like Figure 1 and Figure 3 As shown, in some embodiments, the positioning assembly 3 includes a fixed seat 31, a positioning cylinder 32 and a positioning portion 33, wherein the fixed seat 31 and the base 1 are fixedly connected, the positioning cylinder 32 is arranged on the fixed seat 31, the positioning portion 33 and the positioning cylinder 32 are transmission-connected, and the positioning cylinder 32 can drive the positioning portion 33 and the sound insulation cotton to have an interference fit.

[0137] The fixing seat 31 is the supporting part of the entire positioning assembly 3. During the assembly process of the sound insulation cotton, the positioning cylinder 32 drives the positioning part 33 and the sound insulation cotton to have an interference fit, thereby positioning the sound insulation cotton and ensuring its stability during the assembly process.

[0138] The fixing seat 31 extends along the length direction of the sound insulation cotton. The shape of the fixing seat 31 can be L-shaped, U-shaped, etc. This embodiment is described by taking the fixing seat 31 being set to be L-shaped as an example.

[0139] The positioning cylinder 32 is a linear cylinder, and its telescopic rod is arranged toward the sound insulation cotton. The positioning cylinder 32 drives the telescopic rod to extend, thereby driving the positioning part 33 to move toward the sound insulation cotton and have an interference fit with the sound insulation cotton.

[0140] In some embodiments, the positioning portion 33 includes a mounting seat 331, a pressure plate 332 and a positioning needle 333, wherein the mounting seat 331 is connected to the telescopic rod of the positioning cylinder 32, the pressure plate 332 and the mounting seat 331 are fixedly connected, the pressure plate 332 can be pressed against the outer wall of the sound insulation cotton, and the positioning needle 333 is arranged on the mounting seat 331, and the positioning needle 333 extends to the outside of the pressure plate 332 and can penetrate into the sound insulation cotton.

[0141] During the assembly of the sound insulation cotton, the positioning cylinder 32 drives the positioning part 33 to move toward the sound insulation cotton until the pressure plate 332 in the positioning part 33 presses against the outer wall of the sound insulation cotton, and the positioning needle 333 in the positioning part 33 penetrates the sound insulation cotton, thereby positioning the sound insulation cotton.

[0142] Specifically, the mounting seat 331 and the telescopic rod of the positioning cylinder 32 are fixedly connected, the pressure plate 332 and the mounting seat 331 can be fixed by fasteners or direct welding, the length of the positioning pin 333 is greater than the thickness of the pressure plate 332, and after the positioning pin 333 is fixed to the mounting seat 331, a part of the positioning pin 333 can extend out of the pressure plate 332.

[0143] The side of the pressure plate 332 facing the sound insulation cotton is set as an arc surface, and the pressure plate 332 abuts against the outer wall of the sound insulation cotton through the arc surface. A plurality of positioning pins 333 are provided and arranged side by side on the mounting seat 331 to enhance the positioning strength of the sound insulation cotton. The positioning pins 333 can specifically be steel pins.

[0144] In some embodiments, at least two positioning components 3 are provided, and at least two positioning components 3 are arranged along the circumference of the base 1 to fix different circumferential positions of the sound insulation cotton.

[0145] At least two positioning components 3 are provided, and at least two positioning components 3 can fix different circumferential positions of the sound insulation cotton to enhance the positioning strength of the sound insulation cotton.

[0146] Optionally, two positioning components 3 can be provided, and the two positioning components 3 are arranged at 120° to position and fix two positions of the circumference of the sound insulation cotton, but it is not limited to this. For example, three positioning components 3 can also be provided or three positioning components 3 can be equally divided and arranged on the circumference of the sound insulation cotton.

[0147] In some embodiments, the base 1 includes a first connecting seat 11, a second connecting seat 12 and a connecting column 13, wherein the second connecting seat 12 is spaced below the first connecting seat 11, the clamping assembly 2 and the positioning assembly 3 are both arranged below the second connecting seat 12, and the connecting column 13 is connected to both the first connecting seat 11 and the second connecting seat 12.

[0148] The connecting column 13 is used to connect and fix the first connecting seat 11 and the second connecting seat 12 into one body. The first connecting seat 11 is convenient for assembling furniture and connecting and fixing with an external robot arm. The second connecting seat 12 is used to install the support clamping assembly 2 and the positioning assembly 3.

[0149] Specifically, the first connection seat 11 and the second connection seat 12 can be set as circular seats, the two are concentrically arranged, and three connection columns 13 are arranged and are equally divided along the center of the first connection seat 11 and the second connection seat 12. The driving motor 41 is fixedly arranged on the second connection seat 12, and the plurality of clamping assemblies 2 are equally divided along the center of the second connection seat 12, and the driven gear 43 is arranged at the center of the second connection seat 12.

[0150] In this embodiment, the second connecting seat 12 is provided with a notch along the radial direction of the sound insulation cotton, two guide rails 51 are provided on both sides of the notch, the slide 52 slides in the notch, and the clamping assembly 2 is fixedly provided under the slide 52 to slide synchronously along the guide rail 51 with the slide 52.

[0151] In order to facilitate the understanding of the assembly fixture of this embodiment, the following is a Figure 1 To Attachment Figure 3 The usage process is introduced as follows:

[0152] The position of the clamping assembly 2 is adjusted according to the selected size of the sound insulation cotton. Specifically, the driving motor 41 rotates to drive the active gear 42 to rotate, thereby driving the driven gear 43 to rotate, and driving multiple connecting rods 44 to swing synchronously, thereby driving multiple clamping assemblies 2 to move along the guide rail 51.

[0153] During the movement of the clamping assembly 2 , the position detection assembly 6 is used to detect the limit position of the movement of the clamping assembly 2 to prevent the clamping assembly 2 from moving out of the guide rail 51 .

[0154] The clamping assembly 2 clamps the sound insulation cotton: the clamping cylinder 21 is started, and the clamping cylinder 21 drives the first clamping part 22 and the second clamping part 23 to move toward each other so that the first clamping part 22 is clamped on the outer wall of the sound insulation cotton, and the second clamping part 23 is clamped on the inner wall of the sound insulation cotton. The sound insulation cotton is clamped and fixed at different circumferential positions through multiple clamping assemblies 2.

[0155] The positioning component 3 fixes the sound insulation cotton: the positioning cylinder 32 drives the telescopic rod to extend, driving the mounting seat 331 and the pressure plate 332 and the positioning needle 333 thereon to move toward the sound insulation cotton at the same time, until the pressure plate 332 presses against the outer wall of the sound insulation cotton, and the positioning needle 333 penetrates the sound insulation cotton, thereby achieving positioning and fixation of the sound insulation cotton at at least two circumferential positions through at least two clamping components 2.

[0156] The fixed and positioned sound insulation cotton sleeve can be arranged on the outer periphery of the compressor 100 .

[0157] After each sound insulation cotton assembly is completed, the clamping assembly 2 is controlled to reset, and the origin detection assembly 7 is used to detect whether the clamping assembly 2 is reset to the origin. That is, when the clamping assembly 2 moves to the origin position, the origin detection switch 71 moves exactly to correspond to the origin detection part 72.

[0158] According to an embodiment of the present invention, on the other hand, an assembly robot is disclosed, comprising a mechanical arm and the assembly fixture of the present invention, wherein a base 1 of the assembly fixture is connected to the mechanical arm.

[0159] Since the assembly robot of the present invention includes the assembly fixture of the present invention, it has the same technical effect as the assembly fixture, and this embodiment will not be described in detail herein.

[0160] It can be understood that when the robot drives the sound insulation cotton to move, the positioning component 3 and the clamping component 2 cooperate to effectively clamp and position the sound insulation cotton, which can also greatly reduce the shaking of the sound insulation cotton during movement, thereby avoiding the problem of the sound insulation cotton being skewed due to the shaking, which in turn leads to a decrease in assembly accuracy.

[0161] like Figures 4 to 6 As shown, according to an embodiment of the present invention, on the other hand, an assembly production line is disclosed, including the assembly robot of the present invention.

[0162] Since the assembly production line of the present invention includes the assembly robot of the present invention, it has the same technical effect as the assembly robot, and this embodiment will not be described in detail here.

[0163] In some embodiments, the assembly production line further comprises a finishing component for finishing the sound insulation cotton so that it can be assembled in place.

[0164] By further setting up a sorting component, the sorting component can sort the sound insulation cotton so that it can be assembled in place, thereby improving the assembly accuracy of the sound insulation cotton.

[0165] In some embodiments, the organizing component includes a frame 8, a first organizing mechanism 9 and a second adjustment mechanism, wherein the first organizing mechanism 9 is disposed on the frame 8, and the first organizing mechanism 9 can organize the sound insulation cotton along the length direction of the sound insulation cotton so that it can be assembled in place in the length direction, and the second organizing mechanism 10 is disposed on the frame 8, and the second organizing mechanism 10 can organize the sound insulation cotton along the circumferential direction of the sound insulation cotton so that it can be assembled in place in the circumferential direction.

[0166] The first arranging mechanism 9 is capable of arranging the sound insulation cotton along the length direction so that it can be assembled in place in the length direction. The second arranging mechanism 10 is capable of arranging the sound insulation cotton along the circumferential direction so that it can be assembled in place in the circumferential direction, thereby ensuring the assembly position of the sound insulation cotton in all directions.

[0167] like Figure 4and Figure 5 As shown, in some embodiments, the first sorting mechanism 9 includes a first sorting cylinder 91 and a first sorting part 92, wherein the first sorting cylinder 91 is fixedly arranged on the frame 8, and the first sorting part 92 and the first sorting cylinder 91 are transmission connected, and the first sorting cylinder 91 can drive the first sorting part 92 to push the sound insulation cotton to move and adjust along the length direction.

[0168] The frame 8 installs and fixes the first arranging cylinder 91, and the first arranging cylinder 91 drives the first arranging part 92 to move toward the sound insulation cotton and then pushes the sound insulation cotton to move and adjust along the length direction so that it can be assembled in place in the length direction.

[0169] Specifically, since the second clamping portion 23 clamps the sound insulation cotton during assembly, when the second clamping portion 23 is removed, at least a portion of the sound insulation cotton in the length direction is located outside the compressor 100 and is not assembled. Therefore, the first sorting cylinder 91 drives the first sorting portion 92 to push the sound insulation cotton to continue moving toward the compressor 100 along the length direction, thereby allowing the sound insulation cotton to be completely assembled to the compressor 100.

[0170] In some embodiments, the first finishing portion 92 is a pressure ring, which is sleeved outside the compressor 100 and abuts against the end of the sound insulation cotton.

[0171] The pressure ring can adapt to the end shape of the sound insulation cotton to increase the matching area between the pressure ring and the sound insulation cotton.

[0172] The pressure ring can be a partial circular ring structure or a complete circular ring structure, both of which can match the shape of the end of the sound insulation cotton.

[0173] like Figure 4 and Figure 6 As shown, in some embodiments, the second sorting mechanism 10 includes a second sorting cylinder 101 and a second sorting part 102, wherein the second sorting cylinder 101 is fixedly arranged on the frame 8, and the second sorting part 102 and the second sorting cylinder 101 are transmission connected, and the second sorting cylinder 101 can drive the second sorting part 102 to push the sound insulation cotton located on the outside of the anchor bolt of the compressor 100 to move and adjust toward the compressor 100.

[0174] The frame 8 installs and fixes the second finishing cylinder 101, and the second finishing cylinder 101 drives the second finishing part 102 to move toward the sound insulation cotton and then pushes the sound insulation cotton located outside the anchor bolt of the compressor 100 to move and adjust toward the compressor 100, so that the sound insulation cotton fits against the outer wall of the compressor 100.

[0175] Specifically, since the outer wall of the compressor 100 is provided with other structures and anchor bolts for fixing the compressor 100, the sound insulation cotton is usually provided with a notch to avoid other structures. When the sound insulation cotton sleeve is arranged on the outer periphery of the compressor 100, the notch is easy to open outward in the direction away from the compressor 100, causing the sound insulation cotton sleeve to be on the outside of the anchor bolt. Therefore, the second finishing cylinder 101 can drive the second finishing part 102 to push the sound insulation cotton at the notch so that it is close to the outer wall of the compressor 100 and fits it.

[0176] In some embodiments, the second finishing portion 102 is an arc-shaped push plate, and the arc-shaped push plate matches the outer wall of the sound insulation cotton.

[0177] The arc-shaped push plate can adapt to the shape of the outer wall of the sound insulation cotton to increase the matching area between the arc-shaped push plate and the sound insulation cotton.

[0178] In actual use, the second finishing cylinder 101 is first used to drive the second finishing part 102 to push the sound insulation cotton at the notch so that it is close to the outer wall of the compressor 100, and then the first finishing cylinder 91 is used to drive the first finishing part 92 to push the sound insulation cotton along the length direction toward the compressor 100, so that the sound insulation cotton is completely assembled to the compressor 100.

[0179] Of course, the above description is only the optimal technical solution of this embodiment. In addition:

[0180] In other embodiments, the drive component 4 can also be set as a linear drive structure, and the linear drive mechanism drives the clamping component 2 to move linearly, which can also achieve the same technical effect as this embodiment. The linear drive structure is such as a linear cylinder or a drive structure composed of a motor and a screw.

[0181] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the present application.
