[0004] This application provides an assembly apparatus for assembling a target part to a workpiece. The assembly apparatus includes a first substrate, a pressing structure, a first driving assembly, a locking structure, and a second driving assembly. The first substrate is movably disposed along a first direction. The pressing structure is fixedly connected to the first substrate and can move with the first substrate along the first direction. The pressing structure has a first through hole that passes through the pressing structure along the first direction. The first driving assembly is slidably assembled to the first substrate along the first direction. The locking structure is driven by the first driving assembly and can rotate under the drive of the first driving assembly.

The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0076] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0077] Example

[0078] See Figure 1 The embodiments of this application provide an assembly device 1000, which includes a machine base 200, a storage device 300, a fixture assembly 400, an assembly device 100, and a testing assembly 500.

[0079] The machine tool 200 includes a base plate 201, a gantry assembly 202, and a first moving assembly 203, the first moving assembly 203 being disposed on the gantry assembly 202. A storage device 300 is disposed on the base plate 201 for storing the target part 1.

[0080] A fixture assembly 400 is disposed on the base plate 201 for fixing the workpiece 4. An assembly device 100 is disposed on the first moving assembly 203 for transferring the target part 1 to the workpiece 4 and assembling the target part 1 onto the workpiece 4. A detection assembly 500 is disposed on the first moving assembly 203 for detecting the dimensions of the assembled workpiece 4.

[0081] In this embodiment, the storage device 300 may be a vibratory feeder, used to vibrate the target part 1 to a state that can be grasped by the assembly device 100.

[0082] In this embodiment, the first moving component 203 may be an electric guide rail. The first moving component 203 is movably disposed on the gantry assembly 202 along the second direction X and can drive the assembly device 100 to move along the second direction X.

[0083] In this embodiment, the assembly equipment 1000 further includes a second moving component 401, which may be an electric guide rail, and a fixture assembly 400 is disposed on the second moving component 401. The second moving component 401 is disposed on the base plate 201 along the third direction Y, and can drive the fixture assembly 400 to move in the third direction Y, so as to drive the workpiece 4 to move along the third direction Y to the position corresponding to the assembly device 100.

[0084] In this embodiment, the storage device 300 has a plurality of target components 1. The target components 1 are placed either tilted or upright within the storage device 300. When the target component 1 is in an upright state (e.g., Figure 3 (As shown in the diagram), target part 1 can be grasped by assembly device 100.

[0085] In this embodiment, the detection component 500 can be a CCD image detection device used to locate the target component 1, so that the first moving component 203 can be controlled by the control component to move the assembly device 100 to the corresponding target component 1 and complete the grasping of the target component 1.

[0086] See Figures 1 to 3 In this embodiment, the workpiece 4 includes a plate surface 41, which has multiple screw holes 5. The target part 1 includes a base 2 and a pin 3. The base 2 is cylindrical, and both its inner and outer circumferential surfaces are threaded surfaces. The outer circumferential surface of the base 2 has a first groove 21 extending along the first direction Z, which causes a portion of the threads on the threaded surface to be cut off.

[0087] In this embodiment, the pin 3 is disposed on the side of the first groove 21 away from the workpiece 4 and has a first column extending out of the first groove 21 and a second column located within the first groove 21. The second column has a cutting edge 31, which is located inside the thread root of the first groove 21. When the target part 1 is threadedly engaged with the workpiece 4, the cutting edge 31 does not contact the thread of the screw hole 5. When the target part 1 is screwed into the workpiece 4, the first column corresponds to the thread of the screw hole 5 and can be pressed down to contact the thread of the screw hole 5 and break the thread pair, so that the target part 1 is fixed in the screw hole 5.

[0088] In this embodiment, the assembly device 100 can engage with the threads on the inner circumferential surface of the base 2 of the target part 1 and pick up the target part 1 from the storage device 300.

[0089] In this embodiment, the second moving component 401 moves the fixture component 400 to a position corresponding to the assembly device 100 along the third direction Y. The first moving component 203 can move the assembly device 100 to a position corresponding to the storage device 300 or the fixture component 400 along the first direction Z. The detection component 500 locates the target part 1 in a graspable state, and controls the assembly device 100 to move along the first direction Z to the corresponding storage device 300, grasp the target part 1, and then move to the corresponding fixture component 400 to assemble the target part 1 onto the workpiece 4.

[0090] See Figures 4 to 7In this embodiment, the assembly device 100 includes a first substrate 101, a pressing structure 1011, a first driving assembly 102, a locking structure 103, and a second driving assembly 104. The first substrate 101 is movably disposed along a first direction Z. The pressing structure 1011 is fixedly connected to the first substrate 101 and can move with the first substrate 101 along the first direction Z. The pressing structure 1011 has a first through hole 1016, which passes through the pressing structure 1011 along the first direction Z. The first driving assembly 102 is slidably assembled to the first substrate 101 along the first direction Z. The locking structure 103 is drively connected to the first driving assembly 102 and can rotate under the drive of the first driving assembly 102. The locking structure 103 extends out of the first through hole 1016 along the first direction Z and can rotate under the drive of the first driving assembly 102 to screw the target part 1 into the workpiece 4. The second drive assembly 104 is connected to the first substrate 101 and can drive the first substrate 101 and the pressing structure 1011 to move along the first direction Z, so that the pressing structure 1011 presses down and connects to the target part 1 of the workpiece 4.

[0091] In this embodiment, the pressing structure 1011 and the locking structure 103 are slidably coupled. The pressing structure 1011 can move along the first direction Z under the drive of the first substrate 101, and the locking structure 103 can rotate under the drive of the first driving component 102 to screw the target part 1 into the workpiece 4. Then, the pressing structure 1011 presses the pin 3 of the target part 1 and fixes the target part 1 to the workpiece 4. The second driving component 104 controls the locking structure 103 and the pressing structure 1011 to move along the first direction Z, and the first driving component 102 drives the locking structure 103 to rotate, so that the locking structure 103 can rotate and move at the same time. At the same time, the first driving component 102 can also take into account the pressing action of the pressing structure 1011. The assembly structure is smaller, the operation is simple, and the pressing structure 1011 is fitted onto the locking structure 103, which ensures accurate positioning and high assembly efficiency.

[0092] In this embodiment, the locking structure 103 is slidably fitted to the pressing structure 1011 along the first direction Z. After the locking structure 103 locks the target part 1 to the workpiece 4, the pressing structure 1011 can slide relative to the locking structure 103 along the first direction Z to press down the target part 1.

[0093] In this embodiment, the locking structure 103 and the pressing structure 1011 are slidably engaged. When the locking structure 103 screws the target part 1 into the workpiece 4, the first base plate 101 stops moving. The locking structure 103 can continue to move along the first direction Z under the action of gravity, and screw the target part 1 into the workpiece 4. During this process, the pressing structure 1011 does not contact the target part 1. After screwing in, the second driving component 104 continues to move and drives the pressing structure 1011 to press down on the target part 1, completing the fixing action. The assembly action of the locking structure 103 and the pressing structure 1011 is realized by only two driving components, which is simple in structure and convenient in operation.

[0094] In this embodiment, the assembly device 100 further includes a second substrate 1041 and an elastic component 105. The first substrate 101 is provided with a first track 1018 extending along a first direction Z, and the second substrate 1041 is slidably fitted to the first track 1018. A first driving component 102 is disposed on the second substrate 1041. The elastic component 105 is disposed on the first substrate 101 and includes a fixing rod 1051, a first elastic element 1052, and a second elastic element 1053. The fixing rod 1051 is fixed to the first substrate 101 and extends along the first direction Z. The first elastic element 1052 and the second elastic element 1053 are sequentially sleeved on the fixing rod 1051 circumferentially and confined between the two axial ends of the fixing rod 1051. The second substrate 1041 is provided with a mating portion 1042, which is slidably fitted to the outer periphery of the fixing rod 1051. The first elastic element 1052 and the second elastic element 1053 are respectively located on both sides of the mating portion 1042 along the first direction Z.

[0095] In this embodiment, the second substrate 1041 is supported on the first substrate 101 by elastic members arranged along the first direction Z. The first elastic member 1052 and the second elastic member 1053 of the elastic assembly 105 elastically press the mating portion 1042 of the second substrate 1041 against the middle of the fixing rod 1051. During the transport of the target part 1, the second elastic member 1053 supports the second substrate 1041 and counteracts the weight of the second substrate 1041. When locking is performed, the first elastic member 1052 presses against the second substrate 1041, thereby driving the locking structure 103 to press the target part 1 against the workpiece 4, making it easier to screw the target part 1 into the workpiece 4. After the target part 1 is screwed into the workpiece 4, the locking structure 103 presses against the workpiece 4 and cannot move. Meanwhile, the pressing structure 1011 continues to press down under the drive of the second drive assembly 104. At this time, the elastic component 105 acts as a buffer, preventing the locking structure 103 from applying excessive pressure to the workpiece 4 when the pressing structure 1011 presses against the target part 1, thus preventing damage to the workpiece 4. Simultaneously, the elastic component 105 elastically pushes the pressing structure 1011 away from the target part 1, preventing the pressing structure 1011 from applying excessive pressure and damaging the workpiece 4.

[0096] In this embodiment, the pressing structure 1011 further includes a first base 1012 and a pressing sleeve 1013. The first base 1012 is fixedly connected to the first substrate 101, the pressing sleeve 1013 is rotatably connected to the first substrate 101, and a first through hole 1016 is formed in the pressing sleeve 1013.

[0097] In this embodiment, the pressing sleeve 1013 is rotatably disposed in the first through hole 1016 and can be passively rotated when the locking structure 103 rotates, which reduces the friction between the locking structure 103 and the pressing structure 1011 when the locking structure 103 rotates, making the locking accuracy higher and increasing the service life of the assembly device 100.

[0098] In this embodiment, the locking structure 103 includes a first shaft segment 1031, a second shaft segment 1032, and a locking head 1033 connected sequentially along the axial direction. The first shaft segment 1031 is connected to the first drive assembly 102. The locking head 1033 extends out of the first through hole 1016. The diameter of the second shaft segment 1032 is smaller than that of the first shaft segment 1031. The pressing sleeve 1013 includes a first tube segment 1014 and a second tube segment 1015. One end of the first tube segment 1014 is connected to the first substrate 101, and the first shaft segment 1031 is slidably fitted to the first tube segment 1014. The second tube segment 1015 is connected to the side of the first tube segment 1014 away from the first substrate 101. The diameter of the side of the second tube segment 1015 away from the first tube segment 1014 is smaller than the diameter of the side of the second tube segment 1015 connected to the first tube segment 1014, and the second shaft segment 1032 is slidably fitted to the second tube segment 1015. The second pipe section 1015 can limit the displacement of the first shaft section 1031 along the first direction Z.

[0099] In this embodiment, the diameter of the second pipe section 1015 is smaller than the diameter of the first shaft section 1031, so as to confine the first shaft section 1031 within the first through hole 1016. The second shaft section 1032 can extend out of the first through hole 1016 so that when the target part 1 is screwed in, the locking head 1033 can extend into the screw hole 5 of the workpiece 4.

[0100] In this embodiment, the assembly apparatus 100 further includes a third substrate 106. A first substrate 101 is provided with a first track 1018 extending along a first direction Z, and a second substrate 1041 is slidably fitted to the first track 1018. A locking structure 103 is disposed on the second substrate 1041 and corresponds to the pressing structure 1011 along the first direction Z. The third substrate 106 is provided with a second track 1061 extending along the first direction Z, and the first substrate 101 is slidably fitted to the second track 1061.

[0101] In this embodiment, the second substrate 1041 is slidably disposed on the first substrate 101 along the first direction Z, and the first substrate 101 is slidably disposed on the third substrate 106 along the first direction Z. The third substrate 106 can drive the first substrate 101 and the second substrate 1041 to move along the first direction Z. During assembly, the third substrate 106 drives the second substrate 1041 to move through two stages of sliding, thereby driving the locking structure 103 to complete the locking. After the locking is completed, the third substrate 106 drives the first substrate 101 to move through one stage of sliding, thereby driving the pressing structure 1011 to complete the pressing and fixing.

[0102] In this embodiment, the assembly apparatus 100 further includes a fourth substrate 107 and a third elastic member 108, the third elastic member 108 being disposed between the third substrate 106 and the first substrate 101 along the first direction Z. The fourth substrate 107 includes a third track 1071 extending along the first direction Z, and the third substrate 106 is slidably engaged with the third track 1071.

[0103] In this embodiment, the fourth substrate 107 can drive the third substrate 106 to move along the first direction Z. The third substrate 106 can elastically drive the first substrate 101 to move along the first direction Z through the third elastic member 108. When the pressing structure 1011 is not pressing, the third elastic member 108 can lift the first substrate 101 along the first direction Z to prevent the first substrate 101 from falling due to gravity. When the pressing structure 1011 is pressing, the third elastic member 108 can elastically press the first substrate 101 so that the pressing structure 1011 can fix the target 1 to the workpiece 4, and at the same time has a buffering effect to prevent the pressing structure 1011 from applying too much pressure to the target 1, which would damage the target 1 and the workpiece 4.

[0104] In this embodiment, the second driving component 104 is disposed on the fourth substrate 107 and can drive the third substrate 106 to move along the first direction Z, thereby indirectly driving the first substrate 101 to move along the first direction Z. The second substrate 1041 is disposed on the first moving component 203 and can drive the assembly device 100 to move along the second direction X under the drive of the first moving component 203.

[0105] In this embodiment, the first substrate 101 further includes an extension 1017. The third substrate 106 further includes two limiting blocks 1062, which are located on both sides of the extension 1017 along the first direction Z, to limit the distance that the first substrate 101 moves relative to the third substrate 106 along the first direction Z.

[0106] In this embodiment, the limiting block 1062 restricts the movement of the extension 1017, thereby limiting the movement distance of the pressing structure 1011, so as to avoid the pressing structure 1011 moving too far in the first direction Z, resulting in pressing failure.

[0107] In summary, the embodiments of this application provide an assembly device 1000. A second substrate 1041 is provided with a first driving component 102, which can drive the locking structure 103 to rotate, screwing the target part 1 into the workpiece 4 to complete the locking. The first substrate 101 is provided with a pressing structure 1011, used to press the pin 3 of the target part 1 along the first direction Z after locking is completed. The pin 3 breaks the threaded pair between the target part 1 and the workpiece 4, thereby fixing the target part 1 to the workpiece 4. By setting a multi-stage sliding substrate, multiple components can be controlled by one driving component to move along the first direction Z, completing multiple different movement actions. It also has a buffer structure to prevent damage to the target part 1 and workpiece 4 due to excessive pressure. Before assembly, positioning is achieved by the detection component 500. The pressing structure 1011 of the assembly device 100 is fitted onto the locking structure 103, resulting in high assembly accuracy, simple assembly actions, and improved assembly efficiency.

[0108] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
