[0028] Some embodiments of the application are described in detail. The following embodiments and features of the embodiments can be combined with each other, without conflict.

[0029] Embodiments Referring to Figure 1 The present embodiment provides an assembling device 1000 for assembling a target piece 1 and a workpiece 6, the assembling device 1000 comprising a first jig assembly 10, a second jig assembly 11, a first driving assembly 18, a second driving assembly 19 and a third driving assembly 20.

[0030] In the present embodiment, the workpiece 6 can be a cylindrical component, such as a cylindrical sound casing, or other workpiece 6 having a small diameter opening 8 and a large diameter inner cavity. In the present embodiment, the target piece 1 can be a dust screen with a plastic piece attached to the inner wall of the sound, wherein the dust screen is made of metal material and is bonded to the outer circumferential surface of the plastic piece by glue. The target piece 1 has an adhesive on the outer circumference, and a certain time is required to keep the target piece 1 pressed against the workpiece 6 after the target piece 1 is attached to the workpiece 6, and the workpiece 6 with the target piece 1 is obtained after the adhesive solidifies. In other embodiments, the target piece can also be other components or assemblies that need to be installed on the inner side of the workpiece.

[0031] Referring to Figures 3 to 7In the embodiment, the assembling device 1000 comprises a first positioning protrusion 101, a second jig assembly 11, a first driving assembly 18, a second driving assembly 19 and a third driving assembly 20. The first positioning protrusion 101 is movably arranged for fixing the workpiece 6. The second jig assembly 11 is movably arranged, and comprises a base 12 and a pushing portion 13. The base 12 has a bearing surface 121 arranged at the outer periphery of the base 12, and the bearing surface 121 is used for bearing the target piece 1. The pushing portion 13 is slidably arranged on the base 12, and is used for pushing the target piece 1 to deform and fit the inner surface of the workpiece 6. The first driving assembly 18 is drivingly connected to the first positioning protrusion 101, so as to drive the first positioning protrusion 101 to move to correspond to the second jig assembly 11. The second driving assembly 19 is drivingly connected to the second jig assembly 11, so as to drive the target piece 1 to abut against the workpiece 6. The third driving assembly 20 is drivingly connected to the pushing portion 13, and is used for driving the pushing portion 13 to push the target piece 1 to deform and fit the inner surface of the workpiece 6.

[0032] In the embodiment, the first positioning protrusion 101 is arranged to fix the workpiece 6, and the second jig assembly 11 is arranged to fix the target piece 1. The target piece 1 can be assembled on the second jig assembly 11 in a size smaller than the first jig assembly 10 of the workpiece 6. The first driving assembly 18 drives the workpiece 6 to move to correspond to the target piece 1. The second driving assembly 19 drives the target piece 1 to abut against the workpiece 6. Finally, the third driving assembly 20 drives the pushing portion 13 to push the target piece 1 to deform and fit the surface of the workpiece 6. In this way, the target piece 1 can enter the workpiece 6 in a size smaller than the first jig assembly 10 of the workpiece 6 and fit the inner side of the workpiece 6, thereby solving the problem of difficult assembly between the workpiece 6 and the target piece 1.

[0033] In the embodiment, the assembling device 1000 further comprises a machine table 26 provided with a sliding rail 261 extending along a first direction X. The first jig assembly 10 comprises a base 102 and a connecting plate 103. The base 102 is slidably fitted on the sliding rail 261. The connecting plate 103 has two ends respectively connected to the base 102 and the first driving assembly 18, so that the first driving assembly 18 drives the first jig assembly 10 to move along the first direction X. The first jig assembly 10 is used for fixing the workpiece 6, and can drive the first jig assembly 10 to move along the first direction X from a position away from the second jig assembly 11 to a position corresponding to the second jig assembly 11, so that the target piece 1 corresponds to the mounting position (as shown in FIG. 1) of the inner side of the workpiece 6. During the movement, the target piece 1 passes through the opening 8 of the workpiece 6 and extends into the inner side of the workpiece 6 along the first direction X. Figure 3

[0034] ​In this embodiment, the first direction X, the second direction Z, and the third direction Y are perpendicular to each other. For example, in this embodiment, the first direction X is the length direction of the assembly device 1000 (parallel to the axis of the workpiece 6), the second direction Z is the vertical direction, and the third direction Y is the width direction of the assembly device 1000.

[0035] In this embodiment, the first drive assembly 18 is disposed on one side of the machine tool 26 along the second direction Z, and the first drive assembly 18 is disposed opposite to the first fixture assembly 10. The first drive assembly 18 can be transmitted to the first fixture assembly 10 via the connecting plate 103 to drive the first fixture assembly 10 to move along the first direction X.

[0036] In this embodiment, the machine base 26 is also provided with a limit block 262 (see Figure 1 In the machine tool 26, a limiting block 262 is disposed on the side of the second fixture assembly 11 away from the first fixture assembly 10 along the first direction X. The first drive assembly 18 can drive the first fixture assembly 10 to move along the first direction X until it abuts against the limiting block 262. When the base 102 abuts against the limiting block 262, the second fixture assembly 11 enters the inside of the first fixture assembly 10 through the opening 8, and the second fixture assembly 11 drives the target part 1 into the inside of the workpiece 6 along the first opposite direction, so that the outer peripheral surface of the target part 1 corresponds to the inner cavity of the workpiece 6, which facilitates the third drive assembly 20 to push the target part 1 and fit it against the inner surface of the workpiece 6. By using the limiting block 262 to restrict the position of the first fixture assembly 10 along the first direction X, the positioning operation of the workpiece 6 and the target part 1 along the second direction Z is simplified and the positioning is more accurate.

[0037] In this embodiment, the second jig assembly 11 is movably disposed along the second direction Z. The second jig assembly 11 includes a base 12 and a pushing part 13. The base 12 has a bearing surface 121, which is disposed on the outer periphery of the base 12 and is used to bear the target part 1. The pushing part 13 is slidably disposed on the base 12 and is used to push the target part 1 to deform and fit into the inner surface of the workpiece 6. In this embodiment, the base 12 is generally cylindrical and its axis extends along the first direction X. The bearing surface 121 is the outer peripheral surface of the base 12. The target part 1 surrounds the base 12 and at least part of the target part 1 is in contact with the bearing surface 121 so that the target part 1 is supported on the bearing surface 121 and can move under the drive of the second jig assembly 11.

[0038] In the embodiment, the second driving assembly 19 is arranged on the table 26 and is connected to the second jig assembly 11 in the second direction Z. After the first driving assembly 18 drives the workpiece 6 to make the target piece 1 abut the mounting area inside the workpiece 6, the second driving assembly 19 can drive the second jig assembly 11 to move towards the side of the table 26, so as to drive the part of the target piece 1 close to the table 26 to move to abut the workpiece 6 in the second direction Z. In the embodiment, the second driving assembly 19 is a cylinder, and the transmission end of the second driving assembly 19 is connected to the second jig assembly 11. In other embodiments, the second driving assembly 19 can also be other driving members.

[0039] In the embodiment, the assembling device 1000 further comprises a guide column 263 protruding from the surface of the table 26, and the guide column 263 extends in the second direction Z. The second jig assembly 11 further comprises a guide block 17 (see Figure 2 ), and the guide block 17 is provided with a guide hole 171 (see Figure 2 ). The guide hole 171 penetrates the guide block 17 in the second direction Z. When the second driving assembly 19 drives the second jig assembly 11 to move, the outer circumferential surface of the guide column 263 is matched with the guide hole 171 and can slide along the guide column 263, so as to improve the precision of the second jig assembly 11 moving in the second direction Z and prevent the target piece 1 from deviating when abutting the workpiece 6, and the assembling precision is higher.

[0040] The third driving assembly 20 (see Figure 3 ) is connected to the pushing part 13. After the second driving assembly 19 drives the target piece 1 to make the part of the target piece 1 close to the table 26 abut the workpiece 6, the third driving assembly 20 drives the pushing part 13 to push the target piece 1 to deform and match the inner surface of the workpiece 6. The pushing part 13 comprises a pushing rod 131 and an abutting head 132. The pushing rod 131 is slidably arranged on the base 12, and the abutting head 132 is connected to one end of the pushing rod 131 protruding from the first groove 122. The surface of the abutting head 132 away from the pushing rod 131 is matched with the inner surface of the workpiece 6. The third driving assembly 20 is arranged on the side of the pushing rod 131 away from the abutting head 132 along the length direction of the pushing rod 131 and can drive the pushing rod 131 to push out along the length direction of the pushing rod 131, so as to push the abutting head 132 until the target piece 1 closely matches the inside of the workpiece 6. In the embodiment, the third driving assembly 20 is a cylinder, and the base 12 is provided with an ejection air inlet 201 and a return air inlet 202. The third driving assembly 20 can introduce air into the ejection air inlet 201 to eject the pushing rod 131, or can exhaust air from the return air inlet 202 to form a negative pressure in the base 12 to suck the pushing rod 131 to retract into the first groove 122. In other embodiments, the third driving assembly 20 can also be other driving members.

[0041] In the embodiment, the base 12 is provided with two pushing portions 13 which are arranged along the circumference of the base 12 at intervals to cooperate with the second jig assembly 11 to push the two portions of the target piece 1 outward and expand, and then deform to fit inside the workpiece 6, so that the target piece 1 can be tightly attached to the inside of the workpiece 6. Among them, the two pushing portions 13 are symmetrically distributed along the second direction Z, one of which pushes the side of the target piece 1 close to the first end 2 to fit the workpiece 6, and the other pushes the side of the target piece 1 close to the second end 3 to fit the workpiece 6. In this way, the second jig assembly 11 drives the target piece 1 to move, the middle portion of the target piece 1 fits the workpiece 6, and the two pushing portions 13 respectively push the two sides of the target piece 1 to fit the workpiece 6, so that the outer circumference of the target piece 1 completely fits the inner cavity of the workpiece 6, and the fitting degree is higher.

[0042] In some prior art, the target piece 1 is annular, which is difficult to enter the inside of the workpiece 6 from the small opening 8 of the workpiece 6 when installed in the workpiece 6, and the installation is inconvenient. In the embodiment, the target piece 1 is in a strip shape and is bent around the base 12 to form an annular shape. The target piece 1 has a first end 2 and a second end 3 on both sides along the extension direction thereof, and the first end 2 and the second end 3 overlap along the thickness direction of the target piece 1. The overlapped target piece 1 has a smaller volume and can enter the inside of the workpiece 6 from the opening 8 of the workpiece 6.

[0043] In the embodiment, the volume of the base 12 is smaller than the opening 8 of the workpiece 6, and the target piece 1 can overlap and fit the bearing surface 121 of the base 12, so that the second jig assembly 11 can drive the target piece 1 to enter the inside of the workpiece 6 and assemble. When feeding, the operator only needs to bend the target piece 1 to fit the bearing surface 121, and then fix the target piece 1 by operating the positioning piece 14 to complete the feeding of the target piece 1, which is convenient to operate.

[0044] In the embodiment, the target piece 1 is provided with first through holes 4 which are arranged at intervals along the extension direction thereof, and the first through holes 4 on the first end 2 overlap the first through holes 4 on the second end 3. The base 12 is provided with a first groove 122 which is arranged on the bearing surface 121. The second jig assembly 11 further comprises a positioning piece 14 and an elastic piece 15. The positioning piece 14 is slidably arranged in the first groove 122, and the outer circumference of the positioning piece 14 fits the first through holes 4, so that the positioning piece 14 can pass through the first end 2 and the second end 3 in sequence and fix the target piece 1 to the base 12. The two ends of the elastic piece 15 abut against the positioning piece 14 and the groove bottom surface of the first groove 122 respectively, and provide the positioning piece 14 with an elastic force along the second direction Z to abut against the positioning piece 14 to pass through the first through holes 4. In the embodiment, the elastic piece 15 can be a spring.

[0045] In another embodiment, the positioning member 14 is arranged on the side of the base 12 away from the machine table 26 along the second direction Z, and the positioning member 14 can be clamped to position the target member 1 and fix the target member 1 to the bearing surface 121, preventing the target member 1 from deviating, and the assembly precision is higher. After the second driving assembly 19 drives the target member 1 to abut against the workpiece 6, the pushing part 13 abuts against the first end 2 and the second end 3 of the target member 1, so that the target member 1 is deformed to be disengaged from the positioning of the positioning member 14, and then abuts against and adheres to the inner side surface of the workpiece 6.

[0046] In another embodiment, the positioning member 14 is arranged on the side of the base 12 away from the machine table 26 along the second direction Z, and the positioning member 14 can be clamped to position the target member 1 and fix the target member 1 to the bearing surface 121, preventing the target member 1 from deviating, and the assembly precision is higher. After the second driving assembly 19 drives the target member 1 to abut against the workpiece 6, the fourth driving assembly 21 drives the positioning member 14 to retract from the bearing surface 121, so as to unlock the target member 1, and then the pushing part 13 pushes the target member 1, so that the target member 1 abuts against and adheres to the inner side surface of the workpiece 6.

[0047] In the embodiment, the assembly device 1000 further comprises a first support 23 arranged on the machine table 26 and extending along the second direction Z. The assembly device 1000 further comprises a fourth driving assembly 21 and a transmission rod 24, the middle part of the transmission rod 24 is hinged to the first support 23, and the two ends of the transmission rod 24 are respectively matched with the fourth driving assembly 21 and the positioning member 14, so that the fourth driving assembly 21 drives the positioning member 14 to extend out of the bearing surface 121 or retract into the first recess 122.

[0048] In the embodiment, the middle part of the transmission rod 24 is hinged to the side of the first support 23 away from the machine table 26, and can drive the positioning member 14 to extend out of the first recess 122 or retract under the driving of the fourth driving assembly 21, so as to position the target member 1 or unlock the target member 1.

[0049] In the embodiment, the positioning member 14 comprises a matching part 142 and at least one positioning rod 141, the positioning rod 141 is connected to the side of the matching part 142 away from the machine table 26, and can extend out of the bearing surface 121 along the second direction Z and pass through the first through hole 4 of the first end 2 and the second end 3, so as to fix the target member 1 to the base 12.

[0050] In the embodiment, the matching part 142 is provided with a matching groove 143 extending along the first direction X, and the transmission rod 24 can extend into the matching groove 143 and drive the positioning member 14 to move along the second direction Z by abutting against the two side groove walls of the matching groove 143 along the second direction Z, so as to fix or unlock the target member 1 by the positioning member 14.

[0051] In the embodiment, the combination of the first driving assembly 19, the pushing part 13 and the second driving assembly 20 can drive the target member 1 to abut against the workpiece 6, and then the fourth driving assembly 21 drives the positioning member 14 to retract from the bearing surface 121, so as to unlock the target member 1, and then the pushing part 13 pushes the target member 1, so that the target member 1 abuts against and adheres to the inner side surface of the workpiece 6. Figure 3 and Figure 5As shown, the base 12 is further provided with an avoiding groove 123. The assembling device 1000 further comprises a pressing member 25 and a fifth driving assembly 22. The pressing member 25 has a pressing end 251 and an extension plate 252. One end of the extension plate 252 is drivingly connected to the fifth driving assembly 22, and the other end is connected to the pressing end 251. The pressing end 251 extends into the avoiding groove 123 and can be moved into the avoiding groove 123 or extends out of the avoiding groove 123 and presses the target piece 1 away from one side of the first end 2 and the second end 3 to the workpiece 6 under the driving of the fifth driving assembly 22.

[0052] In this embodiment, the first driving assembly 21 is used to drive the target piece 1 to abut against the workpiece 6. Figure 3 As shown, the base 12 is provided with two avoiding grooves 123. The two avoiding grooves 123 are spaced apart along the third direction Y on the base 12. The pressing member 25 is provided with two pressing ends 251. The two pressing ends 251 are arranged in the two avoiding grooves 123, respectively. The extension plate 252 is connected to the two pressing ends 251 and can drive the pressing ends 251 to press the target piece 1.

[0053] In this embodiment, the opening 8 of the avoiding groove 123 faces the side of the machine table 26, so that the pressing member 25 can press the part of the target piece 1 close to the side of the machine table 26. After the second driving assembly 19 drives the target piece 1 to abut against the workpiece 6, the pressing member 25 extends out of the avoiding groove 123 and presses the part of the target piece 1 close to the side of the machine table 26 to the inside of the workpiece 6, so that the part of the target piece 1 close to the side of the machine table 26 is attached to the inside of the workpiece 6.

[0054] Referring to Figures 3 to 8 In this embodiment, the target piece 1 is provided with a second through hole 5. The workpiece 6 is provided with a third through hole 7. The first jig assembly 10 comprises a first positioning protrusion 101. The second jig assembly 11 further comprises a second positioning protrusion 16.
