[0006] a butt joint mechanism which comprises a sliding sleeve capable of sliding in the first direction along the fixed frame, one end of the sliding sleeve is fixed with a butt joint part which is clamped with a butt joint surface of the component one, and the sliding sleeve is rotationally connected with the fixed frame;
[0007] a rotary driving mechanism which comprises a rotary driving member fixed on the fixed frame and a transmission assembly which synchronously slides with the sliding sleeve, and the rotary driving member drives the sliding sleeve to rotate through the transmission assembly;
[0008] a first elastic member which limits the sliding sleeve at a first position through the transmission assembly, and when the sliding sleeve is pressed by the component one due to misalignment of the gear and the rack, the first elastic member elastically deforms to allow the sliding sleeve to slide towards a side away from the component two.
[0009] The gear meshing assembly device realizes meshing assembly of the gear of the component one and the rack of the component two without manual assembly.
[0010] Considering that the component one and the component two are horizontally spaced on the carrier, the component one needs to be rotated to the angle of the gear and the rack matching to realize the gear engagement, so the sliding sleeve can rotate while moving in the first direction until the gear and the rack are aligned, and the sliding sleeve can push the component one to move to realize the gear engagement.

[0046] The preferred embodiments of the present application are described in detail below with reference to the accompanying drawings, so that the advantages and features of the present application can be more easily understood by those skilled in the art, and the scope of protection of the present application is more clearly defined.
[0047] In the following figure, the first direction is the front-rear direction in the figure.
[0048] Referring to the accompanying drawings Figure 6 and the accompanyingFigure 7 As shown in the figure, component one 100 and component two 200 are placed on a carrier 300 in a first direction, component one 100 includes a gear shaft 102, the gear shaft 102 is provided with a gear 101 on one side and an abutting surface 103 on the other side, the abutting surface 103 is provided with a gear step, component two 200 includes a gear rack 201. Component two 200 is fixed on the carrier 300, when the gear 101 and the gear rack 201 are aligned, component one 100 can be pushed to move towards component two 200. Initially, the gear 101 and the gear rack 201 are not engaged, the assembly device can push component one 100 to move in the first direction to approach component two 200 and drive component one 100 to rotate synchronously until the gear 101 and the gear rack 201 are engaged.
[0049] Referring to the accompanying Figure 1 As shown in the figure, the assembly device includes a horizontal movement driving member 2, a fixed frame 1, an abutting mechanism 3, a rotation driving mechanism 4 and a first elastic member 5.
[0050] The fixed frame 1 is connected with the horizontal movement driving member 2 and can move linearly reciprocatingly in the first direction under the driving of the horizontal movement driving member 2, the abutting mechanism 3, the rotation driving mechanism 4 and the first elastic member 5 are arranged on the fixed frame 1 and move synchronously with the fixed frame 1.
[0051] Referring to the accompanying Figure 2 As shown in the figure, the abutting mechanism 3 includes a sliding sleeve 31 which can slide in the first direction on the fixed frame 1, one end of the sliding sleeve 31 is fixed with an abutting part 311 which is clamped with the abutting surface 103 of component one 100, the sliding sleeve 31 is rotationally connected with the fixed frame 1. The abutting part 311 is provided with a clamping groove corresponding to the gear step, when the gear step and the clamping groove are clamped, the sliding sleeve 31 will drive component one 100 to rotate synchronously in the rotating process. The horizontal movement driving member 2 drives the sliding sleeve 31 to move towards component two 200, and then pushes component one 100 to move towards component two 200, but only when the gear 101 and the gear rack 201 are aligned, component one 100 can be pushed to move until the gear rack 201 and the gear 101 are engaged, otherwise component one 100 cannot move. Therefore, the sliding sleeve 31 can slide relative to the fixed frame 1 while rotating, when the gear rack 201 and the gear 101 are not aligned, the sliding sleeve 31 can slide relative to the fixed frame 1 instead of advancing synchronously when the fixed frame 1 is driven to move by the horizontal movement driving member 2, avoiding damage to component one 100 or component two 200 caused by rigidly pushing component one 100.
[0052] The rotating driving mechanism 4 comprises a rotating driving part 41 fixed on the fixed frame 1 and a transmission assembly 42 synchronously sliding with the sliding sleeve 31, the rotating driving part 41 drives the sliding sleeve 31 to rotate through the transmission assembly 42. The first elastic part 5 limits the sliding sleeve 31 in the first position through the transmission assembly 42, and when the sliding sleeve 31 is pressed by the part one 100 due to the misalignment of the gear 101 and the rack 201, the first elastic part 5 elastically deforms to allow the sliding sleeve 31 to slide towards the side away from the part two 200, at this time the first elastic part 5 continues to accumulate force until the part one 100 rotates to the alignment of the gear 101 and the rack 201, the first elastic part 5 pushes the part one 100 to move quickly to make the gear 101 and the rack 201 engage.
[0053] In this embodiment, the assembling device realizes the engagement assembly of the gear 101 of the part one 100 and the rack 201 of the part two 200 without manual assembly. When designing the assembling device, it is considered that the part one 100 and the part two 200 are horizontally and separately placed on the carrier 300, so the part one 100 needs to be rotated to the angle at which the gear 101 and the rack 201 cooperate to realize the gear engagement, so the sliding sleeve 31 can rotate while moving in the first direction until the sliding sleeve 31 can push the part one 100 to move to realize the gear engagement when the sliding sleeve 31 rotates to the alignment of the gear 101 and the rack 201. In this process, in order to avoid that the hard pushing of the first part causes the damage of the part one 100 or the part two 200, the sliding sleeve 31 in this embodiment can slide relative to the fixed frame 1 while synchronously moving with the fixed frame 1, which makes room for the part two 200 when the gear 101 and the rack 201 are not aligned, the first elastic part 5 accumulates force, and the first elastic part 5 pushes the part one 100 to move quickly to realize the gear engagement of the gear 101 and the rack 201 at the moment when the part one 100 rotates to the alignment of the gear 101 and the rack 201.
[0054] When the assembly device is in gear engagement, the fixed frame 1 is first driven by the horizontal movement driving member 2 to move forward towards the carrier 300 until the butt joint portion 311 and the butt joint surface 103 are clamped. Then, the rotating driving member 41 can drive the sliding sleeve 31 and the component one 100 to rotate through the transmission assembly 42. During the rotation, the horizontal movement mechanism continues to drive the fixed frame 1 to move forward. When the gear 101 of the component one 100 and the gear rack 201 of the component two 200 are aligned, the sliding sleeve 31 can move forward synchronously with the fixed frame 1 to realize the gear engagement of the gear 101 and the gear rack 201. After the engagement, the gear 101 cannot continue to rotate, and at this time, the rotating driving member 41 detects that the torque becomes larger and stops working. When the gear 101 of the component one 100 and the gear rack 201 of the component two 200 are not aligned, the sliding sleeve 31 is fixed under the pressure of the component one 100 (moves backward relative to the forward moving fixed frame 1), and at this time, the first elastic member 5 is continuously compressed and the sliding sleeve 31 can continue to rotate. At the moment when the gear rack 201 and the gear 101 are aligned, the first elastic member 5 pushes the sliding sleeve 31 to move forward to realize the gear engagement of the gear 101 and the gear rack 201.
[0055] In this embodiment, the assembly device can realize the gear engagement assembly of the gear 101 and the gear rack 201, and can effectively protect the component one 100 and the component two 200.
[0056] Referring to FIG. 1, Figure 3 As shown, the output end of the rotating driving member 41 is fixed with a rotating shaft 411 penetrating through the fixed frame 1, and the rotating shaft 411 is fixed with a connecting key. The rotating shaft 411 can drive the sliding sleeve 31 to rotate through the transmission assembly 42, and the transmission assembly 42 needs to be able to slide synchronously relative to the rotating shaft 411 with the sliding sleeve 31.
[0057] The transmission assembly 42 includes a driving wheel 421, a driven wheel 422 and a transmission belt 423 surrounding the driving wheel 421 and the driven wheel 422. The driving wheel 421 is sleeved on the rotating shaft 411 and is connected with the connecting key. The driven wheel 422 is fixedly connected with the other end of the sliding sleeve 31. At this time, when the rotating shaft 411 rotates, the driving wheel 421 is driven to rotate synchronously through the connecting key, and in turn, the sliding sleeve 31 is driven to rotate synchronously through the transmission belt 423 and the driven wheel 422. The driving wheel 421 can slide along the connecting key, and when the sliding sleeve 31 slides relative to the fixed frame 1, the driving wheel 421 is pulled to slide synchronously through the flexible transmission belt 423. However, the driving wheel 421 is always connected with the connecting key during the sliding process and will not slide out of the connecting key.
[0058] The driving wheel 421 and the driven wheel 422 each include a wheel body and a baffle at both ends of the wheel body. The transmission belt is located between the two baffles and does not cross the baffles, so that the driving wheel 421 and the driven wheel 422 can be pulled to move synchronously through the transmission belt.
[0059] The structure of the transmission assembly 42 and the rotating shaft 411 can ensure that the rotating driving part 41 fixed on the fixed frame 1 drives the sliding sleeve 31 to rotate, and at the same time, the sliding sleeve 31 can pull the transmission assembly 42 to slide synchronously relative to the rotating shaft 411, so that the sliding sleeve 31 can be driven to rotate by the rotating driving part 41 under the premise that the rotating driving part 41 is fixed relative to the fixed frame 1, and the sliding sleeve 31 can move relative to the fixed frame 1.
[0060] The first elastic member 5 is a compression spring, the first spring sleeve is sleeved on the rotating shaft 411 and located on the side of the driving wheel 421 away from the rotating driving part 41, and the elastic force of the first elastic member 5 is directly applied to the driving wheel 421 and then transmitted to the driven wheel 422 and the sliding sleeve 31 through the transmission belt 423. The rotating shaft 411 is provided with a limiting portion 4111 located between the driving wheel 421 and the fixed frame 1, and when the sliding sleeve 31 is limited in the first position, the first elastic member 5 presses the driving wheel 421 against the limiting portion 4111, and the limiting portion 4111 is used to limit the position of the driving wheel 421, thereby limiting the position of the sliding sleeve 31 in the first position. When the driving wheel 421 abuts against the limiting portion 4111, the first elastic member 5 is in a compressed state or a natural state.
[0061] The limiting portion 4111 has a gap to the fixed frame 1, because the limiting portion 4111 rotates and does not contact the fixed frame 1, so that the fixed frame 1 cannot hinder the rotation of the rotating shaft 411, and wear is not generated between the two.
[0062] The rotating shaft 411 is further provided with an adjusting member 4112 for adjusting the position of the rotating shaft 411 in the first direction, the adjusting member 4112 can slide along the rotating shaft 411 and be fixed to the rotating shaft 411 (such as threaded connection, interference fit). The first elastic member 5 is located between the adjusting member 4112 and the driving wheel 421, and the two ends of the first elastic member 5 abut against the ends of the adjusting member 4112 and the driving wheel 421, respectively. By adjusting the position of the adjusting member 4112, the elastic force of the first elastic member 5 in the initial state can be adjusted, so that the first elastic member 5 can keep the sliding sleeve 31 in the first position at the beginning, and when the sliding sleeve 31 is pressed by the component one 100, the pushing force of the first elastic member 5 applied to the sliding sleeve 31 can overcome the gravity of the component one 100 to move the sliding sleeve 31.
[0063] Referring to FIG. 1, Figure 2 As shown in the drawings, the fixed frame 1 has a door type structure, and the two vertical plates of the fixed frame 1 are provided with bearings, and the sliding sleeve 31 passes through the bearings, and the bearings can ensure the rotation of the sliding sleeve 31 and also allow the sliding of the sliding sleeve 31.
[0064] In order to avoid the position deviation of the component one 100 and the component two 200 in the tooth engagement process and affect the assembly, the assembly device further comprises a positioning assembly 6, which positions the component one 100 and the component two 200 before the contacting part of the docking mechanism 3 contacts the component one 100.
[0065] Referring to Figs. 1 and 2, Figure 2 and Figs. 3 and 4, Figure 3 As shown in Figs. 1 and 2, the positioning assembly 6 includes positioning post one 61 and positioning post two 62, which correspond to component one 100 and component two 200 respectively. The positioning post two 62 can be pressed against the upper surface of the component two 200 to press the component two 200 against the carrier 300, so that the component two 200 cannot move and its position is kept unchanged. When the positioning post one 61 defines the position of the component one 100, the component one 100 and the positioning post one 61 are virtually connected, that is, there is a spacing of less than 0.05 mm between the positioning post one 61 and the component one 100. At this time, the positioning post one 61 neither presses the component one 100 so that it cannot move in the first direction, nor defines the position of the component one 100 in the up-down direction before the docking mechanism 3 contacts the component one 100, thereby ensuring that the component one 100 can only move axially under the influence of vibration.
[0066] In one embodiment, the positioning post one 61 is a spring positioning pin, which includes a fixed sleeve, a sliding rod and a spring. The positioning post one 61 is arranged in an elastic structure, so that even if the positioning post one 61 and the component one 100 abut, the pressure applied by the positioning post one 61 on the component one 100 is small, and the first elastic member 5 can overcome this pressure to move the component one 100.
[0067] The positioning assembly 6 and the transverse driving member 2 are fixed together on a connecting plate 7, and the connecting plate 7 is connected with the lifting driving member. The lifting driving member drives the connecting plate 7 to move downward, and the docking mechanism 3 starts to dock with the component one 100 only after the positioning assembly 6 completes the positioning of the component one 100 and the component two 200.
[0068] Because even if there is the positioning post one 61, the component one 100 can still move in the front-back direction due to vibration, therefore, in one embodiment, referring to Figs. 5 and 6, Figure 2 and Figs. 7 and 8, Figure 4 As shown in Figs. 5 and 6, the docking mechanism 3 further includes a docking shaft 32 coaxial with the gear shaft 102, and the component one 100 includes the gear shaft 102 extending out of the docking surface 103. The docking shaft 32 is sleeved with the docking shaft 32 first before being clamped with the connecting portion and the docking surface 103. When the sliding sleeve 31 rotates, the docking shaft 32 restricts the axial movement of the component one 100, and cooperates with the positioning post one 61 and the carrier 300 to restrict the component one 100 from escaping.
[0069] The end of the docking shaft 32 is provided with a sleeving hole 323, and the gear shaft 102 can be inserted into the sleeving hole 323. The diameter of the sleeving hole 323 is slightly larger than the diameter of the gear shaft 102. For example, the diameter of the gear shaft 102 is 2.8 mm, and the diameter of the sleeving hole 323 is 3 mm.
[0070] In the embodiment, the docking shaft 32 rotates synchronously with the sliding sleeve 31 and can slide along the sliding sleeve 31 in the first direction. The docking shaft 32 is arranged coaxially in the sliding sleeve 31. When the docking shaft 32 is sleeved on the gear shaft 102, the horizontal moving mechanism drives the fixed frame 1 to continue moving forward, but at this time, the docking shaft 32 cannot push the component 100 to move while avoiding axial movement of the gear shaft 102, so the docking shaft 32 needs to slide relative to the sliding sleeve 31.
[0071] The docking mechanism 3 further comprises a second elastic member 33, which limits the docking shaft 32 in an initial position. Because the gear shaft 102 extends out of the docking surface 103, the initial position of the docking shaft 32 needs to ensure that the docking shaft 32 is inserted into the gear shaft 102 before the docking portion 311 is clamped with the docking surface 103. For example, the initial position of the docking shaft 32 is a position in which the end of the docking portion 311 is flush with the end of the docking shaft 32.
[0072] When the docking shaft 32 is pressed by the gear shaft 102, the component 100 does not slide and the second elastic member 33 is elastically deformed to allow the docking shaft 32 to slide towards the side away from the component 200 until the docking portion 311 is clamped with the docking surface 103. The elastic force of the second elastic member 33 is very small, and the component 100 cannot be always pushed to move forward only by the elastic force of the second elastic member 33, so the docking shaft 32 only plays a role of positioning the gear shaft 102.
[0073] The second elastic member 33 is a compression spring, which is arranged in the sliding sleeve 31 and abuts against the bottom of the sliding sleeve 31 at one end and abuts against the docking shaft 32 at the other end. When the docking shaft 32 moves towards the rear under the pressure of the component 100, the first elastic member 5 is continuously compressed.
[0074] Referring to FIGS. 1 to 3, Figure 3 and FIGS. 4 to 6, Figure 5 in order to realize synchronous rotation of the sliding sleeve 31 and the docking shaft 32 and guide the sliding of the docking shaft 32, a guide groove 312 extending along the axial direction of the sliding sleeve 31 is formed on the sliding sleeve 31, and a guide rod 321 fixedly arranged in the guide groove 312 is arranged on the docking shaft 32. The guide groove 312 extends along the axial direction of the sliding sleeve 31, and the width of the guide groove 312 matches the guide rod 321. The guide rod 321 can only slide in the guide groove 312, so that the docking shaft 32 can only slide along the sliding sleeve 31.
[0075] A plurality of guide rods 321 are arranged, and a plurality of guide grooves 312 are arranged at this time. The plurality of guide grooves 312 are uniformly distributed in the circumferential direction of the sliding sleeve 31, and the plurality of guide grooves 312 simultaneously guide the sliding of the docking shaft 32, so as to ensure accurate alignment of the docking shaft 32 and the gear shaft 102.
[0076] A plurality of guide rods 321 are fixed with a limiting block 322 outside the sliding sleeve 31, and the fixing frame 1 is provided with a limiting column 11 for limiting the position of the limiting block 322. The limiting column 11 is located in front of the limiting block 322, that is, the initial position of the guide rod 321, when the limiting column 11 and the limiting block 322 abut, the guide rod 321 is in the initial position, at this time, the end of the guide rod 321 is extended out of the connecting part, and the second elastic member 33 is in a compressed state or a natural state, so as to limit the guide rod 321 in this position.
[0077] The limiting column 11 is threadedly connected with the fixing frame 1, and the position of the limiting column 11 is adjustable, so as to adjust the initial position of the guide rod 321.
[0078] In an embodiment, referring to FIG. 2, the connecting plate 7 is further provided with a fine adjustment platform 63, and the pressing assembly is arranged on the fine adjustment platform 63. Figure 2 The fine adjustment platform 63 adjusts the position of the pressing assembly, so that the pressing assembly is aligned with the component one 100 and the component two 200.
[0079] When the assembling device in the embodiment works, first, the connecting plate 7 moves downward, the positioning column two 62 abuts against the component two 200, and the positioning column one 61 reaches a position which is less than 0.05 mm from the component one 100, at this time, the positioning assembly 6 completes the preliminary positioning of the component one 100 and the component two 200.
