[0003] The drum of an existing drum washing machine usually includes an outer drum and an inner drum. The outer drum is usually made of plastic and is used to hold water. The inner drum is made of stainless steel and has water-permeable holes in the drum body for holding washed clothes. The outer drum needs to be sleeved with the inner drum for use. Specifically, an inner drum shaft is fixed at the rear center of the inner drum, and a through hole coaxial with the outer drum is provided at the bottom of the outer drum. When the outer drum and the inner drum are sleeved, the inner drum shaft passes through the through hole at the bottom of the outer drum to connect with the rotor of the motor. The inner drum shaft is used to transmit rotational power, and the inner drum rotates under the drive of the motor.

[0004] Prior art CN215546436U discloses a washing machine inner barrel assembly mechanism, comprising a first conveying device, the first conveying device is used to convey the inner barrel of the washing machine to be assembled, the inner barrel is horizontally placed on the first conveying device; a second conveying device, the second conveying device is used to convey the outer barrel of the washing machine to be assembled, the outer barrel is vertically placed on the first conveying device; a flipping device, arranged at the conveying end of the first conveying device, is used to receive the inner barrel and flip the inner barrel from a horizontal direction to a vertical direction; a robot, is used to clamp the inner barrel flipped by the flipping device, and place the inner barrel in the outer barrel; a visual positioning device, is used to obtain the center coordinate data of the outer barrel, and send it to the robot, and the robot places the inner barrel in the outer barrel according to the center coordinate data. In this way, the automatic assembly of the inner barrel is realized, the assembly efficiency and assembly accuracy are higher, and the labor intensity of the workers is reduced.

[0005] Another example is the prior art CN208178853U which discloses an automatic press-fitting machine for stainless steel inner barrel and rear barrel of a drum washing machine, comprising a chain plate line mechanism, the output terminal of the chain plate line mechanism is provided with a stainless steel inner barrel lifting and positioning mechanism, the stainless steel inner barrel lifting and positioning mechanism comprises a fixed seat, a stainless steel inner barrel gripping mechanism is arranged above the stainless steel inner barrel lifting and positioning mechanism, the stainless steel inner barrel gripping mechanism comprises a guide rail, a gripping mechanism is arranged on the guide rail, a tooling plate lifting and positioning mechanism and a rear barrel lifting and positioning mechanism are arranged below the stainless steel inner barrel gripping mechanism, the rear barrel lifting and positioning mechanism comprises a positioning shaft arranged on a tooling plate limit plate, the tooling plate lifting and positioning mechanism and the rear barrel lifting and positioning mechanism are arranged side by side and the arrangement direction is perpendicular to the arrangement direction of the chain plate line mechanism.

Summary of the invention

[0007] The purpose of the present invention is to provide a drum washing machine sleeve method and device to solve the problems of operating space, effect and efficiency of the inner and outer drum sleeve, reduce the operating space of the sleeve, and improve the sleeve effect and efficiency of the inner and outer drum.

[0008] In order to achieve the above object, the present invention adopts the following technical solution: a drum washing machine sleeve method, comprising the following steps:

[0009] S1, convey the inner tube horizontally to the assembly station with the tube mouth facing downward;

[0010] S2, the inner tube rises and leaves the first conveying line;

[0011] S3, obtaining the axis coordinates of the inner cylinder at the mounting station;

[0012] S4, convey the outer tube downward to the inspection station with the tube mouth facing downward;

[0013] S5, obtaining the axis coordinates of the outer cylinder, and comparing and analyzing them with the axis coordinates of the inner cylinder to obtain the deviation of the inner cylinder relative to the outer cylinder;

[0014] S6. Horizontally adjust the position of the inner cylinder so that the axis of the inner cylinder coincides with the axis of the outer cylinder in the vertical direction;

[0015] S7, transporting the outer cylinder from the inspection station to the mounting station and mounting it on the inner cylinder to form an inner-outer cylinder assembly;

[0016] S8, driving the inner and outer cylinder assembly to descend and then send it away from the assembly station;

[0017] S9. Loop from S1 to S8.

[0018] After adopting the above technical scheme, the present invention has the following advantages: the inner cylinder is horizontally conveyed to the fitting station with the cylinder mouth facing downward, and the outer cylinder is downwardly conveyed to the inspection station with the cylinder mouth facing downward, the axial coordinates of the inner cylinder and the outer cylinder are obtained and the deviation of the inner cylinder relative to the outer cylinder is compared and analyzed, and after the position of the inner cylinder is horizontally adjusted, the outer cylinder at the inspection station is continuously conveyed downward and fitted on the inner cylinder. During the fitting process, the inner cylinder is horizontally conveyed and the outer cylinder is downwardly conveyed. Both the inner cylinder and the outer cylinder are conveyed to the fitting station for fitting. Compared with the method of holding the inner barrel and fitting it on the outer barrel by a robot in the prior art CN215546436U, the inner cylinder is horizontally conveyed and the outer cylinder is vertically conveyed. The operating space required during the fitting process is small, which is convenient for arranging multiple fitting machines in a limited space; and the inner cylinder is at the fitting station, which reduces the deviation of the inner cylinder and reduces the horizontal position of the inner cylinder. Adjustment distance; Compared with the prior art CN208178853U, during the assembly process, the axial coordinates of the inner cylinder and the outer cylinder are obtained in turn, and then the position of the inner cylinder is adjusted horizontally according to the deviation between the axial coordinates. Even if the first conveying line and the conveying equipment of the outer cylinder cause the position of the inner cylinder and the outer cylinder to deviate due to force majeure factors such as wear during the conveying process, the obtained axial coordinates can be adjusted so that the inner cylinder and the outer cylinder overlap in the vertical direction, avoiding the lower side of the outer cylinder from abutting against the upper side of the inner cylinder, improving the assembly effect of the inner cylinder and the outer cylinder, avoiding the need for the first conveying equipment or the outer cylinder conveying equipment to stop for adjustment, thereby improving the assembly efficiency of the inner cylinder and the outer cylinder; and the outer cylinder conveying equipment is downwardly conveyed, and there is basically no deviation in the vertical direction, further reducing the deviation when the inner cylinder and the outer cylinder are assembled.

[0019] In order to achieve the above-mentioned purpose, the present invention also adopts the following technical scheme: a drum washing machine sleeve device, using the above-mentioned drum washing machine sleeve method, including a frame and a first conveyor line, a set station, and a second conveyor line arranged on the frame, the frame is provided with an adjustment device and a visual alignment device, the first conveyor line extends horizontally and passes under the set station to achieve S1, the first conveyor line has a support member for positioning the inner drum with the drum mouth facing downward, the adjustment device is located below the first conveyor line and drives the support member to rise and fall to achieve S2 or S8, or horizontally adjusts the position of the support member to achieve S6, the second conveyor line extends vertically downward and the end section is higher than The first conveyor line and the second conveyor line have an inspection station at the end section and an end point at the assembly station. The second conveyor line has a clamping assembly that conveys the outer cylinder downward to the assembly station with the cylinder mouth facing downward. The clamping assembly drives the outer cylinder to be conveyed downward to the inspection station to achieve S4, and conveyed downward to the assembly station and assembled on the outer side of the inner cylinder to form an inner-outer cylinder assembly to achieve S7. The visual alignment device is located above the first conveyor line. The visual alignment device obtains the coordinates of the axis of the inner cylinder and the axis of the outer cylinder and analyzes the deviation of the coordinates of the axis of the inner cylinder relative to the outer cylinder to achieve S3 and S5. The first conveyor line sends the inner-outer cylinder assembly away from the assembly station to achieve S8.

[0020] By adopting the above-mentioned technical scheme, the inner cylinder is horizontally conveyed to the sleeve station through the first conveyor line, so that the inner cylinder arrives at the designated sleeve station, and the inner cylinder is prevented from deviating from the sleeve station and increasing the adjustment range of the inner cylinder, thereby affecting the sleeve efficiency; the support is driven to separate from the first conveyor line by the adjustment device, so that the visual alignment device can obtain the axis coordinates of the inner cylinder located at the sleeve station, and the support is separated from the first conveyor line, so that the position of the inner cylinder is determined, and the subsequent horizontal adjustment of the inner cylinder is convenient; the outer cylinder is vertically conveyed downward by the second conveyor line, so that the outer cylinder can directly reach the sleeve during the conveying process The inner barrel is transported to the installation station, and the conveying is stopped and obtained through the visual alignment device when entering the inspection station. The visual alignment device obtains the axis coordinates of the inner barrel and the axis coordinates of the outer barrel, which is convenient for determining the adjustment direction and movement amount of the inner barrel, so that the axis coordinates of the inner barrel and the outer barrel coincide in the vertical direction, and the accuracy of the inner barrel and the outer barrel when they are installed is improved. Therefore, compared with the method of the robot clamping the inner barrel and the outer barrel in the prior art CN215546436U, the inner barrel is transported horizontally to the installation station, and the outer barrel is transported vertically downward to the installation station, so that the deviation of the inner barrel and the outer barrel in the vertical direction is The inner cylinder obtains the axis coordinates at the set station, and the terminal of the second conveyor line for conveying the outer cylinder is also located at the set station, which reduces the operating space required for the set of the inner cylinder and the outer cylinder. When the inner cylinder is at the set station, the space required for the inner cylinder to move is also small when the inner cylinder needs to be adjusted, thereby reducing the operating space required for the set of the inner cylinder and the outer cylinder; compared with the prior art CN208178853U, during the set process, the axis coordinates of the inner cylinder and the outer cylinder are obtained in turn, and then the position of the inner cylinder is adjusted horizontally according to the deviation between the axis coordinates. Even if the first conveyor line and the second conveyor line are in the conveying In the process, if the positions of the inner cylinder and the outer cylinder deviate due to force majeure factors such as wear, they can also be adjusted according to the axis coordinates obtained before the sheathing, so that the inner cylinder and the outer cylinder overlap in the vertical direction, avoiding the lower side of the outer cylinder from abutting against the upper side of the inner cylinder, improving the sheathing effect of the inner cylinder and the outer cylinder, avoiding the need for the first conveying device or the outer cylinder conveying device to stop for adjustment, and thus improving the sheathing efficiency of the inner cylinder and the outer cylinder; and the outer cylinder conveying device is vertically conveyed downward, and there is basically no deviation in the orientation in the vertical direction, further reducing the deviation when the inner cylinder and the outer cylinder are sheathed.

[0021] Furthermore, a third conveyor line is provided below the first conveyor line for conveying the support member located at the tail end of the first conveyor line to the head end of the first conveyor line. The adjustment device includes a first lifting assembly and a horizontal adjustment assembly. Both the first lifting assembly and the horizontal adjustment assembly are located between the first conveyor line and the third conveyor line. The horizontal adjustment assembly is used to horizontally adjust the position of the support member to achieve S7. The first lifting assembly drives the horizontal adjustment assembly to connect with the support member to move the inner cylinder to the set station to achieve S2 or drive the support member back to the first conveyor line to achieve S8.

[0022] By adopting the above-mentioned technical scheme, when conveying the inner cylinder, the inner cylinder is placed on the support with the cylinder mouth facing downward, and the first conveyor line drives the inner cylinder to be conveyed to the set station to prevent the inner cylinder from deviating from the set station during the conveying process. The first conveyor line conveys the set inner and outer cylinder assembly from the set station to the tail end of the first conveyor line, and the inner and outer cylinder assembly is sent away from the set station through the first conveyor line, which is convenient for the conveying of the inner and outer cylinder assembly, and convenient for the next unset inner cylinder to be conveyed to the set station to obtain the axis coordinates and wait for the set of the outer cylinder; after the inner cylinder is conveyed to the set station, the first lifting component is started to drive the horizontal adjustment component to rise, so as to lift the support and separate from the first conveyor line, and prevent the unset inner cylinder from being sent away from the set station. After the support is conveyed to the tail end of the first conveyor line with the first conveyor line, the support is sent back to the head end of the first conveyor line through the third conveyor line, so that the support is recycled on the first conveyor line, and it is avoided that after the conveying of the support is completed, the inner cylinder needs to wait for the support for a long time, which affects the conveying of the inner cylinder, and then the set of the inner cylinder and the outer cylinder is prevented.

[0023] Furthermore, the frame is provided with a mounting frame, which is located between the first conveyor line and the third conveyor line. The first lifting assembly is sunk and mounted on the mounting frame. The lower edge of the first lifting assembly is lower than the upper edge of the support member, and the support member avoids the first lifting assembly.

[0024] By adopting the above-mentioned technical scheme, the first lifting assembly and the horizontal adjustment assembly are installed through the mounting frame, which is convenient for the installation of the first lifting assembly and the horizontal adjustment assembly between the first conveyor line and the third conveyor line, and is convenient for driving the inner cylinder to rise and leave the first conveyor line, or the inner and outer cylinder assemblies to descend and contact the first conveyor line and then be sent away from the assembly station, so as to avoid the first conveyor line affecting the horizontal adjustment assembly to drive the support member to adjust horizontally. The first lifting assembly is sunken and installed on the mounting frame, and the support member avoids the lower side of the first lifting assembly, so as to avoid the support member colliding with the lower side of the first lifting assembly when being transported on the third conveyor line.

[0025] Furthermore, the support member has a supporting step surface and a limit block, the limit blocks have multiple pieces and are distributed on both sides of the length direction of the first conveyor line, the inner cylinder is supported on the supporting step surface and is located between the multiple limit blocks, and the minimum distance between the multiple limit blocks in the width direction of the first conveyor line is greater than the distance between the first lifting assembly in the width direction of the first conveyor line so that the limit blocks avoid the first lifting assembly.

[0026] By adopting the above-mentioned technical solution, the inner cylinder is placed on the support and supported on the support step surface, so that the inner cylinder support is placed on the support, the support is further positioned, and the deviation between the axial coordinates of the inner cylinder and the axial coordinates of the outer cylinder is reduced, thereby reducing the subsequent adjustment range of the inner cylinder; the limit block blocks the inner cylinder on the support to prevent the inner cylinder from moving relative to the support during the transportation of the first conveyor line and affecting the axial position of the inner cylinder, thereby reducing the time required for adjusting the position of the inner cylinder, thereby improving the efficiency of the inner and outer cylinder assembly.

[0027] Furthermore, the horizontal adjustment component has a positioning piece, and a positioning hole is provided on the lower side of the support plate. After the first lifting component drives the horizontal adjustment component to connect with the support piece, the positioning piece cooperates with the positioning hole.

[0028] By adopting the above-mentioned technical solution, the horizontal adjustment component and the support member cooperate with each other through the positioning member and the positioning hole, so that the horizontal adjustment component can drive the support member and the inner cylinder to move horizontally to adjust the position of the inner cylinder, thereby avoiding the support member moving relative to the horizontal adjustment component during the horizontal adjustment process, which causes the axes of the inner cylinder and the outer cylinder to not coincide in the vertical direction after the horizontal adjustment, thereby ensuring the fitting effect of the inner cylinder and the outer cylinder.

[0029] Furthermore, the visual alignment device includes a control system and a CCD visual alignment component. The CCD visual alignment component is electrically connected to the control system and obtains coordinate information of the axis of the inner cylinder and the axis of the outer cylinder and transmits it to the control system. The first lifting component and the horizontal adjustment component are electrically connected to the control system. The control system calculates the deviation of the inner cylinder relative to the outer cylinder based on the coordinate information, and controls the horizontal movement of the support member based on the deviation to adjust the position of the inner cylinder so that the axis of the inner cylinder coincides with the axis of the outer cylinder in the vertical direction.

[0030] By adopting the above-mentioned technical scheme, when the visual alignment device detects the axial coordinates of the inner cylinder and the outer cylinder, the axial coordinates of the inner cylinder and the outer cylinder are detected by the CCD visual alignment component, and the data of the detected axial coordinates are transmitted to the control system, and the axial coordinates of the inner cylinder and the outer cylinder are recorded by the control system, and the deviation amount and deviation direction of the inner cylinder relative to the outer cylinder are calculated and compared and analyzed based on the recorded coordinates, and then the control system controls the horizontal adjustment device to adjust the position of the inner cylinder, so as to improve the overlap of the axes of the inner cylinder and the outer cylinder in the vertical direction, thereby improving the alignment effect and efficiency when the inner cylinder and the outer cylinder are installed.

[0031] Furthermore, the CCD vision alignment component obtains the coordinate information of the axis center of the inner cylinder located at the assembly station and transmits it to the control system to implement S3, the CCD vision alignment component obtains the coordinate information of the axis center of the outer cylinder located at the detection station to implement S8 and transmits it to the control system, the control system calculates the deviation of the inner cylinder relative to the outer cylinder and controls the horizontal adjustment component to drive the support to move to horizontally adjust the position of the inner cylinder.

[0032] By adopting the above-mentioned technical scheme, when the CCD vision alignment component detects the axial coordinates of the inner cylinder and the outer cylinder, the axial coordinates of the inner cylinder at the detection station are first detected, and the detection result is transmitted to the control system, and then the axial coordinates of the outer cylinder located at the detection station are detected by the CCD vision alignment component. The axial coordinates of the inner cylinder and the outer cylinder are detected respectively, so as to improve the accuracy of the axial coordinates detected by the inner cylinder and the outer cylinder, and the axial coordinates of the inner cylinder and the axial coordinates of the outer cylinder can be obtained by the same CCD vision alignment component, and the acquisition standard of the axial coordinates is the same, so as to avoid the deviation between the relevant data of the axial coordinates and the actual data, thereby improving the accuracy of the axial coordinates of the inner cylinder and the axial coordinates of the outer cylinder.

[0033] Furthermore, the frame is provided with a horizontal moving component, and the CCD visual alignment component is arranged on the horizontal moving component and is located above the detection station. The horizontal moving component drives the CCD visual alignment component to deviate from the second conveyor line so that the second conveyor line and the clamping component drive the outer cylinder to be vertically conveyed downward to the detection station. After the outer cylinder arrives at the detection station, the horizontal moving component drives the CCD visual alignment component to move above the detection station to obtain the axis coordinate information of the outer cylinder.

[0034] By adopting the above-mentioned technical solution, the CCD vision alignment component is installed on the horizontal moving component, and the CCD vision alignment component is driven to move by the horizontal moving component, so that the same CCD vision alignment component can be used to respectively detect the axial coordinates of the inner cylinder and the outer cylinder. At the same time, the CCD vision alignment component is driven to move by the horizontal moving component to avoid collision between the outer cylinder and the CCD vision alignment component during downward transportation.

[0035] Furthermore, a second lifting assembly is provided on the horizontal moving assembly, and the CCD vision alignment assembly is provided on the second lifting assembly. The second lifting assembly drives the CCD vision alignment assembly to rise and fall, so that the distance between the CCD vision alignment assembly and the upper side surface of the inner cylinder when obtaining the axial coordinates of the inner cylinder is substantially equal to the distance between the CCD vision alignment assembly and the upper side surface of the outer cylinder when obtaining the axial coordinates of the outer cylinder.

[0036] By adopting the above-mentioned technical solution, the CCD vision alignment component is driven to rise and fall through the installation of the second lifting component, so that the distance between the upper end surface of the inner cylinder and the upper end surface of the outer cylinder is the same when the CCD vision alignment component detects the distance between the inner cylinder and the outer cylinder, thereby avoiding the need for the CCD vision alignment component to focus again during the detection process, thereby improving the detection efficiency of the axial coordinates of the inner cylinder and the outer cylinder; in addition, the CCD vision alignment component can use a fixed focal length device to reduce the cost of the vision alignment equipment.

[0047] The technical solution of the present invention is described in detail with specific embodiments below. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0048] In the first embodiment, the present invention provides a drum washing machine sleeve method, comprising the following steps:

[0049] S1, convey the inner tube 23 horizontally to the assembly station 22 with the tube mouth facing downward;

[0050] S2, the inner tube 23 rises and leaves the first conveying line 2;

[0051] S3, obtaining the axis coordinates of the inner cylinder 23 at the mounting station 22;

[0052] S4, conveying the outer cylinder 33 downward to the inspection station 32 with the cylinder mouth facing downward;

[0053] S5, obtaining the axis coordinates of the outer cylinder 33, and comparing and analyzing them with the axis coordinates of the inner cylinder 23 to obtain the deviation of the inner cylinder 23 relative to the outer cylinder 33;

[0054] S6, horizontally adjusting the position of the inner cylinder 23 so that the axis of the inner cylinder 23 coincides with the axis of the outer cylinder 33 in the vertical direction;

[0055] S7, transporting the outer cylinder 33 from the inspection station 32 to the mounting station 22 and mounting it on the inner cylinder 23 to form an inner-outer cylinder assembly;

[0056] S8, driving the inner and outer cylinder assembly to descend and then send it away from the assembly station 22;

[0057] S9. Loop from S1 to S8.

[0058] During the assembly, the inner cylinder 23 is transported horizontally to the assembly station 22, and the outer cylinder 33 is transported vertically downward to the inspection station 32, and then transported from the inspection station 32 to the assembly station 22. During the assembly, there is no need to carry the inner cylinder 23 or the outer cylinder 33 additionally, thereby reducing the operating space required for the assembly. The axis coordinates of the inner cylinder 23 are first obtained, and then the axis coordinates of the outer cylinder 33 are obtained. Since the outer cylinder 33 is transported vertically downward, the outer cylinder 33 basically does not deviate in the vertical direction. After the inner cylinder 23 is worn on the first conveyor line 2, it may cause the inner cylinder 23 to deviate. However, before the inner cylinder 23 and the outer cylinder 33 are assembled, the axis coordinates of the inner cylinder 23 are obtained. The deviation of the inner cylinder 23 relative to the outer cylinder 33 is obtained by analyzing and comparing the axial coordinates of the mark and the outer cylinder 33, and then the position of the inner cylinder 23 is adjusted horizontally to reduce the influence of the deviation of the inner cylinder 23 relative to the outer cylinder 33 on the fitting of the inner cylinder 23 and the outer cylinder 33, thereby improving the accuracy of the fitting of the inner cylinder 23 and the outer cylinder 33. After the inner cylinder 23 is adjusted horizontally, the deviation of the first conveyor line 2 due to wear has little influence on the fitting of the inner cylinder 23 and the outer cylinder 33. Therefore, the influence of wear on the fitting of the inner cylinder 23 and the outer cylinder 33 is reduced, the effect and efficiency of the fitting of the inner cylinder 23 and the outer cylinder 33 are improved, and the need to stop the machine to adjust the equipment to reduce the deviation of the inner cylinder 23 relative to the outer cylinder 33 caused by wear is avoided.

[0059] like Figure 1 and Figure 2 As shown, in the second embodiment, the present invention further provides a drum washing machine sleeve device, and a drum washing machine sleeve method in the first embodiment is applied in this embodiment. Specifically, it includes a frame 1 and a first conveyor line 2, a set station 22, and a second conveyor line 3 arranged on the frame 1. The frame 1 is also provided with an adjustment device 4 and a visual alignment device 5.

[0060] Specifically, Figure 1 and Figure 2 As shown, the first conveyor line 2 extends horizontally and passes under the casing station 22. The first conveyor line 2 is provided with a support 21. When the inner cylinder 23 is conveyed, the inner cylinder 23 is placed on the support 21 with the cylinder mouth facing downward. The first conveyor line 2 drives the support 21 on which the inner cylinder 23 is placed to be conveyed from the head end of the first conveyor line 2 to the casing station 22, thereby realizing S1. The adjusting device 4 is located below the first conveyor line 2. When the support 21 conveys the inner cylinder 23 to the casing station 22 along with the first conveyor line 2, the adjusting device 4 drives the support 21 to separate from the first conveyor line 2, thereby driving the inner cylinder 23 to separate from the first conveyor line 2 and reach the casing station 22, thereby preventing the inner cylinder 23 from being conveyed along the first conveyor line 2 and affecting the acquisition of the axial coordinates of the inner cylinder 23 and the casing of the inner cylinder 23 and the outer cylinder 33, thereby realizing S2.

[0061] In order to prevent the inner cylinder 23 from moving relative to the support member 21 during the conveying process of the first conveying line 2, as shown in FIG. Figure 3As shown, the support member 21 has a support step surface 212 and a limit block 211, wherein the limit block 211 has multiple pieces and is distributed on both sides of the length direction of the first conveyor line 2. When the inner cylinder 23 is placed on the support member 21, the inner cylinder 23 is supported on the support step surface 212, and the inner cylinder 23 is located between the multiple limit blocks 211. The inner cylinder 23 is placed on the support step surface 212, which facilitates the positioning of the inner cylinder 23 on the support member 21, and then facilitates the stable placement of the inner cylinder 23 on the support member 21. The limit block 211 blocks the inner cylinder 23 to prevent the inner cylinder 23 from moving relative to the support member 21 during the conveying process of the first conveyor line 2 and affecting the positioning effect of the inner cylinder 23, and to prevent the deviation between the axial coordinates of the inner cylinder 23 and the axial coordinates of the outer cylinder 33 from increasing due to the movement of the inner cylinder 23 relative to the support member 21.

[0062] In another embodiment, if Figure 4 As shown, the support step surface 212 is arranged on the limit block 211, and a plurality of support step surfaces 212 are arranged on the limit block 211. In this embodiment, there are mainly two support step surfaces 212. The two support step surfaces 212 are respectively a first support step surface 2121 and a second support step surface 2122. The second support step surface 2122 is located above the first support step surface 2121, and the vertical side walls of the first support step surface 2121 and the second support step surface 2122 are respectively corresponding to the inner cylinders 23 of different outer diameters. By setting a plurality of support step surfaces 212, it is convenient to place the inner cylinders 23 of different outer diameters, and then it is convenient to fit the inner cylinders 23 of different sizes with the outer cylinder 33.

[0063] To facilitate the transportation of the outer cylinder 33, Figure 1 , Figure 2 and Figure 5As shown, the second conveyor line 3 extends vertically downward, the end section of the second conveyor line 3 is higher than the first conveyor line 2, the end section of the second conveyor line 3 has a detection station 32 and the end point of the second conveyor line 3 is located at the set station 22, the detection station 32 is located above the set station 22, and the second conveyor line 3 has a clamping assembly 31 that conveys the outer cylinder 33 downward to the set station 22 with the cylinder mouth facing downward; specifically, the clamping assembly 31 includes two clamping blocks 311 and a clamping driving member 312 that drives the two clamping blocks 311 to move closer to or away from each other, and the clamping driving member 312 drives the two clamping blocks 311 to move closer to or away from each other. The outer cylinder 33 is moved closer to be clamped, and then the outer cylinder 33 is vertically conveyed downwardly through the second conveyor line 3, and the outer cylinder 33 is conveyed to the inspection station 32 with the tube mouth facing downward, to implement S4, the visual alignment device 5 obtains the axial coordinates of the outer cylinder 33, and after the adjustment device 4 adjusts the axial position of the inner cylinder 23, the clamping assembly 31 and the outer cylinder 33 are driven by the second conveyor line 3 to be conveyed vertically downwardly to the assembly station 22 again. After the outer cylinder 33 arrives at the assembly station 22, the clamping drive 312 is started, and the two clamping blocks 311 move away from each other and then put down the outer cylinder 33, so that the outer cylinder 33 is assembled on the outer peripheral side of the inner cylinder 23.

[0064] In order to facilitate the visual alignment device 5 to obtain the axis coordinates and compare and analyze the deviation, Figure 1 and Figure 2 As shown, the visual alignment device 5 includes a CCD visual alignment component 51 and a control system. The CCD visual alignment component 51 is electrically connected to the control system. The axis coordinates of the inner cylinder 23 and the axis coordinates of the outer cylinder 33 obtained by the CCD visual alignment component 51 are transmitted to the control system. The control system performs comparative analysis to obtain the deviation of the inner cylinder 23 relative to the outer cylinder 33. Specifically, the CCD visual alignment component 51 takes the center point of the set station 22 as the coordinate origin. After the inner cylinder 23 is driven by the adjustment device 4 to separate from the first conveyor line 2, the CCD visual alignment component 51 obtains the axis coordinates of the inner cylinder 23 to implement S3, and transmits the obtained axis coordinate data information of the inner cylinder 23 to the control system. to the control system, which records the axial coordinates of the inner cylinder 23; after the outer cylinder 33 arrives at the detection station 32 under the transportation of the second conveyor line 3, the CCD visual alignment component 51 detects the axial coordinates of the outer cylinder 33, and transmits the axial coordinate data information of the outer cylinder 33 to the control system, and the control system compares and analyzes the received axial coordinates of the outer cylinder 33 with the recorded axial coordinates of the inner cylinder 23 to obtain the deviation between the axial coordinates of the inner cylinder 23 and the axial coordinates of the outer cylinder 33. The deviation referred to in this embodiment specifically includes the deviation amount and the deviation direction, thereby realizing S5; the adjustment device 4 adjusts the position of the inner cylinder 23 horizontally according to the deviation amount and the deviation direction obtained by the comparison and analysis of the control system.

[0065] Specifically, Figure 6As shown, the adjustment device 4 includes a first lifting component 41 and a horizontal adjustment component 42. The frame 1 is provided with a mounting frame 11, and the mounting frame 11 is located below the first conveyor line 2. The first lifting component 41 is sunken and installed on the mounting frame 11. The horizontal adjustment component 42 is arranged on the first lifting component 41. The first lifting component 41 drives the horizontal adjustment component 42 and the support member 21 to rise and fall; the horizontal adjustment component 42 includes a first horizontal adjustment member 421 and a second horizontal adjustment member 422. The first horizontal adjustment member 421 is arranged on the first lifting component 41. The first horizontal adjustment member 421 drives the support member 21 to rise and fall along the first conveyor line 2 The second horizontal adjustment member 422 moves horizontally in the length direction. The second horizontal adjustment member 422 is arranged on the first horizontal adjustment member 421. The second horizontal adjustment member 422 drives the support member 21 to move horizontally along the width direction of the first conveyor line 2. The first horizontal adjustment member 421 and the second horizontal adjustment member 422 are both electrically connected to the control system. After the control system analyzes the deviation amount and deviation orientation between the axial coordinates of the inner cylinder 23 relative to the axial coordinates of the outer cylinder 33, the moving direction and movement amount of the first horizontal adjustment member 421 and the second horizontal adjustment member 422 are controlled to make the axis center of the inner cylinder 23 coincide with the axis center of the outer cylinder 33 in the vertical direction, thereby realizing S6.

[0066] In order to prevent the support member 21 from sliding relative to the second horizontal adjustment member 422 during the horizontal adjustment process, Figure 6 As shown, a positioning piece 423 is set on the upper side of the second horizontal adjustment piece 422, and a positioning hole is set on the lower side of the support piece 21. When the first lifting assembly 41 drives the first horizontal adjustment piece 421 and the second horizontal adjustment piece 422 to move upward and contact the support piece 21, the positioning piece 423 is plugged into the positioning hole, wherein there are multiple positioning pieces 423 and multiple positioning holes, and the multiple positioning pieces 423 correspond to the multiple positioning holes one by one and are plugged into, and the support piece 21 is horizontally adjusted to adjust the position of the inner cylinder 23; by plugging the positioning piece 423 into the positioning hole, the support piece 21 is prevented from horizontally moving relative to the second horizontal adjustment piece 422, ensuring that the axis of the inner cylinder 23 and the axis of the outer cylinder 33 coincide in the vertical direction after adjustment.

[0067] After the axial position adjustment of the inner cylinder 23 is completed, the second conveyor line 3 is started to drive the clamping assembly 31 and the outer cylinder 33 to be conveyed vertically downward, so that the outer cylinder 33 moves from the detection station 32 to the assembly station 22, and is assembled with the inner cylinder 23 to form an inner and outer cylinder assembly, thereby realizing S7.

[0068] When the outer cylinder 33 is fitted on the inner cylinder 23, compared with the prior art CN215546436U, the inner cylinder 23 is transported horizontally to the fitting station 22, and the outer cylinder 33 is transported vertically downward to the fitting station 22, so that the operating space required for the inner cylinder 23 or the outer cylinder 33 during the fitting process is smaller, which is convenient for arranging multiple sets of equipment in a limited space, and there is no need to consider the additional operating space required for fitting during the arrangement process.

[0069] Compared with the prior art CN208178853U, the axis coordinates of the inner cylinder 23 and the outer cylinder 33 are obtained separately, and the position of the inner cylinder 23 is adjusted horizontally to ensure that the axis of the inner cylinder 23 and the axis of the outer cylinder 33 coincide in the vertical direction each time the outer cylinder 33 is fitted into the inner cylinder 23, so as to avoid that the outer cylinder 33 cannot be well fitted into the outer peripheral side of the inner cylinder 23, thereby improving the fitting effect of the inner cylinder 23 and the outer cylinder 33; in addition, in this embodiment, although the deviation amount of the inner cylinder 23 and the outer cylinder 33 in the vertical direction will increase appropriately due to wear, However, when the outer cylinder 33 is mounted on the inner cylinder 23, the position of the inner cylinder 23 is adjusted solely by the first horizontal adjustment member 421 and the second horizontal adjustment member 422. Therefore, the deviation in the position of the inner cylinder 23 caused by friction has little effect on the inner cylinder 23 and the outer cylinder 33 after the horizontal adjustment. Therefore, compared with the prior art CN208178853U, this embodiment greatly reduces the need to stop the equipment to adjust to improve the mounting effect of the inner cylinder 23 and the outer cylinder 33, thereby improving the mounting effect and efficiency of the inner cylinder 23 and the outer cylinder 33.

[0070] After the inner cylinder 23 and the outer cylinder 33 are assembled, the first horizontal adjustment member 421 and the second horizontal adjustment member 422 reset the direction and offset of the horizontal adjustment, and then start the first lifting assembly 41 to drive the support member 21 to descend, so that the support member 21 contacts the first conveyor line 2, and then the inner and outer cylinder assembly is taken away from the assembly station 22 through the first conveyor line 2 to achieve S8.

[0071] By circulating S1 to S8, the sleeve device is continuously sleeved on the inner drum 23 and the outer drum 33, so that the sleeve device of the drum washing machine is continuously operated.

[0072] In order to facilitate the recycling of the support member 21, Figure 2 and Figure 6 As shown, the frame 1 is provided with a third conveyor line 6, and the third conveyor line 6 is located below the first conveyor line 2 and the mounting frame 11. The third conveyor line 6 conveys the support member 21 at the tail end of the first conveyor line 2 from the tail end of the first conveyor line 2 to the head end of the first conveyor line 2, so as to facilitate the recycling of the support member 21 and, at the same time, speed up the conveyance of the support member 21, so as to avoid the inner cylinder 23 waiting for the support member 21 at the head end of the first conveyor line 2 and affect the assembly efficiency of the inner cylinder 23 and the outer cylinder 33.

[0073] Since the first lifting assembly 41 is installed downward on the mounting frame 11, Figure 6As shown in the figure, the limiting block 211 provided on the support member 21 needs to avoid the lower side of the first lifting assembly 41. Specifically, the minimum distance of the limiting block 211 in the width direction of the first conveyor line 2 is L2, and the distance of the lower side of the first lifting assembly 41 in the width direction of the first conveyor line 2 is L1, where L1 < L2. When the third conveyor line 6 drives the support member 21 to be conveyed from the tail end of the first conveyor line 2 to the head end of the first conveyor line 2, the limiting block 211 avoids the first lifting assembly 41, preventing the limiting block 211 from colliding with the first lifting assembly 41 when the support member 21 is conveyed on the third conveyor line 6.

[0074] In another embodiment, as Figure 2 and Figure 7 shown, to facilitate using the same CCD vision alignment component 51 to detect the axial center coordinates of the inner cylinder 23 and the axial center coordinates of the outer cylinder 33, a horizontal movement component 12 is provided on the frame 1. The CCD vision alignment component 51 is arranged on the horizontal movement component 12 and is located above the detection station 32. After the detection of the axial center coordinates of the inner cylinder 23 is completed, the horizontal movement component 12 drives the CCD vision alignment component 51 to deviate from the second conveyor line 3, preventing the outer cylinder 33 from colliding with the CCD vision alignment component 51 during the vertical downward conveyance process. Using the same CCD vision alignment component 51 to obtain the axial center coordinates of the inner cylinder 23 and the axial center coordinates of the outer cylinder 33 reduces the number of CCD vision alignment components 51 and the cost of the CCD vision alignment components 51.

[0075] To further reduce the cost of the CCD vision alignment component 51, as Figure 2 and Figure 7 shown, a second lifting component 13 is provided on the horizontal movement component 12, and the CCD vision alignment component 51 is arranged on the second lifting component 13. When detecting the axial center coordinates of the outer cylinder 33, the second lifting component 13 drives the CCD vision alignment component 51 to lift and lower, so that when the CCD vision alignment component 51 obtains the axial center coordinates of the inner cylinder 23 and the axial center coordinates of the outer cylinder 33, the distance between the CCD vision alignment component 51 and the upper side of the inner cylinder 23 and the distance between the CCD vision alignment component 51 and the upper side of the outer cylinder 33 are basically equal. It should be noted that the so-called "basically equal" here refers to the distance range where the CCD vision alignment component 51 does not require additional focusing, and a CCD vision alignment component 51 with a fixed focal length can also be used, reducing the cost of the CCD vision alignment component 51, while improving the acquisition speed of the axial center coordinates of the outer cylinder 33, and thus improving the assembly efficiency of the inner cylinder 23 and the outer cylinder 33.

[0076] In addition to the above preferred embodiments, the present invention has other implementation manners.
