Technical Field

[0001] This utility model relates to the field of resistor assembly technology, and in particular to an attachment device. Background Technology

[0002] In the assembly of arc-shaped variable resistors, traditional assembly usually uses manual or simple mechanical assistance to attach the resistor to the base. Since the resistor itself is a straight thin sheet structure, when it is attached to the arc-shaped base, positional deviation or poor adhesion can easily occur, which can easily lead to unstable performance of the arc-shaped variable resistor.

[0003] Therefore, the above problems urgently need to be solved. Utility Model Content

When the second connecting member moves to the connection position between the first horizontal rail and the inclined rail, the lifting component abuts against the free end. When the second connecting member moves to the connection position between the second horizontal rail and the inclined rail, the lifting component faces the suspended end and lifts the suspended end to the starting end.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0057] Please see Figures 1 to 7 This embodiment proposes an attachment device for attaching a resistor 100 to an arc-shaped base 200. The device includes a support portion 1, a locking portion 2, a rotating portion 3, and a lifting portion 4. The support portion 1 supports the resistor 100, and one end of the resistor 100 extends to the outside of the support portion 1 to form a free end 120. An adhesive 110 is provided on the top of the resistor 100, and one end of the adhesive 110 extends to the outside of the support portion 1 along with the free end 120 to form a suspended end 111. The fixing part 2 is disposed above the supporting part 1. The locking part 2 is used to lock the base 200 and keep the base 200 and the colloid 110 aligned in the vertical plane. The rotating part 3 is connected to the locking part 2 and is used to drive the base 200 to rotate around the axis of the base 200 in the rotation direction. The lifting part 4 is disposed below the free end 120 and can lift the free end 120 when the base 200 rotates to the point where its starting end 210 is aligned with the suspended end 111, so that the suspended end 111 adheres to the starting end 210. Here, the starting end 210 of the base 200 refers to the front end when rotating around the rotation direction.

[0058] It is understandable that the resistor 100 is placed on the support part 1, and the free end 120 of the resistor 100 extends to the outside of the support part 1 to ensure that the suspended end 111 and the starting end 210 are precisely aligned in the vertical plane. This ensures the adhesion accuracy between the resistor 100 and the base 200 during the adhesion process. The base 200 can rotate in the rotation direction under the action of the rotating part 3. With the lifting action of the lifting part 4, the entire adhesive 110 can be adhered to the base 200, so that the suspended end 111 of the adhesive 110 gradually extends and adheres to the arc surface of the base 200. This avoids the generation of air bubbles in the resistor 100 during the adhesion process, thereby ensuring the adhesion quality between the resistor 100 and the base 200.

[0059] Furthermore, the attachment device also includes a lateral moving part 5 and a limiting part 6. The lateral moving part 5 is connected to the bearing part 1, the locking part 2 and the lifting part 4, and the lifting part 4 and the locking part 2 are directly opposite each other in the vertical direction. The lateral moving part 5 is used to synchronously drive the bearing part 1, the locking part 2 and the lifting part 4 to move laterally in the first direction. The limiting part 6 is used to limit the resistor 100 so that it remains in the initial position during the attachment process. Understandably, during the movement of the support part 1, the position of the resistor 100 remains unchanged under the action of the limiting part 6, keeping it in its initial position. That is, the support part 1 can gradually detach from the resistor 100 during the movement. At this time, the locking part 2 and the lifting part 4 can move closer to the suspended end 111 under the action of the lateral moving part 5. When the starting end 210, the suspended end 111, and the lifting part 4 are directly aligned in the vertical direction, the lifting member 42 can lift the suspended end 111 to the starting end 210. With the continuous movement of the support part 1, the locking part 2, and the lifting part 4, the attachment of the resistor 100 can be completed. Furthermore, during the attachment process, the lifting part 4 can maintain contact with the resistor 100, thereby further ensuring the attachment accuracy between the resistor 100 and the base 200.

[0060] Specifically, the transverse moving part 5 includes a transverse moving module 51 and a first connecting member 52. The transverse moving module 51 has a transverse moving end 511 that moves transversely in a first direction, and a locking part 2 is disposed on the transverse moving end 511. One end of the first connecting member 52 is connected to the transverse moving end 511, and the other end is connected to both the supporting part 1 and the lifting part 4. It can be understood that the locking part 2 is directly disposed on the transverse moving end 511, and the lifting part 4 and the supporting part 1 are disposed on the transverse moving end 511 through the first connecting member 52. This arrangement can reduce the number of driving structures and also ensure that the supporting part 1, the lifting part 4 and the locking part 2 move synchronously, so as to further ensure the attachment accuracy of the resistor during the attachment process.

[0061] For example, a connecting plate is provided on the horizontal moving end 511 along the vertical direction, the locking part 2 is fixed on the connecting plate, the first connecting member 52 is a connecting rod, one end of the connecting rod is fixed on the connecting plate and is located below the locking part 2, and the other end is fixed to the bearing part 1 and the lifting part 4 by bolts.

[0062] In this embodiment, the supporting part 1 includes two guide rails 11 arranged along a first direction and a moving platform 12 slidably disposed on the guide rails 11. One end of the moving platform 12 is connected to the first connecting member 52 and moves synchronously with the locking part 2 under the action of the first connecting member 52. The moving platform 12 includes a supporting surface 121 for supporting the resistor 100 and a mounting surface 122 for mounting the lifting part 4. The height of the mounting surface 122 is lower than the height of the supporting surface 121.

[0063] Specifically, the lifting part 4 includes a lifting rod 41, a lifting member 42, a second connecting member 43, and a height adjusting member 44. The lifting rod 41 is slidably disposed on the bearing part 1 in a vertical direction; the lifting member 42 is disposed at one end of the lifting rod 41 facing the resistor 100; the second connecting member 43 is disposed at the other end of the lifting rod 41; the height adjusting member 44 is disposed below the lifting rod 41 in a first direction, and along the moving direction of the transverse moving end 511, the height adjusting member 44 sequentially includes a first horizontal track for the second connecting member 43 to slide on. 441, inclined track 442 and second horizontal track 443, the height of the first horizontal track 441 is lower than that of the second horizontal track 443, and when the second connecting member 43 moves to the connection position of the first horizontal track 441 and the inclined track 442, the lifting member 42 abuts against the free end 120. When the second connecting member 43 moves to the connection position of the second horizontal track 443 and the inclined track 442, the lifting member 42 is directly opposite the suspended end 111 and lifts the suspended end 111 to the starting end 210.

[0064] It is understood that the height adjustment component 44 is located below the moving platform 12 and between the two guide rails 11. The lifting rod 41 is connected to the first horizontal rail 441, the inclined rail 442 and the second horizontal rail 443 through the second connector 43. During the movement of the transverse module 51, the second connector 43 can pass through the first horizontal rail 441, the inclined rail 442 and the second horizontal rail 443 in sequence. When the second connector 43 moves to the connection position of the first horizontal rail 441 and the inclined rail 442, the lifting component 42 abuts against the free end 120. Under the action of the inclined rail 442, the height of the lifting rod 41 can be continuously increased, so that the free end 120 can gradually move closer to the base 200. When it moves to the connection position of the second horizontal rail 443 and the inclined rail 442, the lifting component 42 can lift the suspended end 111 to the starting end 210. Under the action of the second horizontal rail 443, the height of the lifting component 42 can remain unchanged to complete the attachment of the resistor.

[0065] Preferably, the second connector 43 is a ball bearing or a rotating shaft that is adapted to the first horizontal rail 441, the inclined rail 442 and the second horizontal rail 443, thereby reducing wear between the second connector 43 and the height adjustment member 44 and improving service life.

[0066] Furthermore, the lifting part 4 also includes a buffer mechanism 45, which is disposed between the lifting rod 41 and the lifting member 42. The buffer mechanism 45 is used to buffer the adhesion pressure on the resistor 100. It can be understood that, under the action of the buffer mechanism 45, rigid contact between the free end 120 and the base 200 can be avoided when the lifting member 42 lifts the free end 120 to the base 200, thereby buffering the adhesion pressure on the resistor 100 and avoiding damage to the resistor 100 during the adhesion process.

[0067] Specifically, the buffer mechanism 45 includes a first buffer plate 451, a second buffer plate 452, and a buffer spring 453. The first buffer plate 451 is disposed at one end of the lifting rod 41; the second buffer plate 452 is disposed above the first buffer plate 451 at intervals, and the lifting member 42 is connected to the second buffer plate 452; the buffer spring 453 is disposed vertically, with one end fixed to the first buffer plate 451 and the other end disposed on the second buffer plate 452. It can be understood that during the movement of the lifting rod 41 in the first direction, it can drive the buffer mechanism 45 to move upward, that is, it can drive the second buffer plate 452 to move upward. When the resistor comes into contact with the base 200, under the reaction force applied by the base 200 to the resistor, the second buffer plate 452 moves closer to the first buffer plate 451, and the buffer spring 453 can be compressed to buffer the attachment pressure on the resistor 100, so as to avoid damage to the resistor 100 during the attachment process.

[0068] Preferably, the buffer mechanism 45 further includes a guide post 454, one end of which is fixedly connected to the second buffer plate 452, and the other end passes through and slides through the first buffer plate 451. A buffer spring 453 is sleeved on the guide post 454 to prevent the buffer spring 453 from shifting during compression and reset, thereby ensuring the attachment accuracy of the resistor.

[0069] The lifting member 42 is preferably a cylindrical cam, which is vertically rotatably mounted on the second buffer plate 452, and the thickness of the cylindrical cam is no greater than the width of the resistor 100. It is understood that when the resistor is in contact with the base 200, the lifting member 42 can rotate around its own axis, thereby reducing wear between it and the resistor and ensuring the adhesion quality of the resistor.

[0070] In this embodiment, the limiting part 6 includes two limiting members 61 and a clamping member 62. The two limiting members 61 are spaced apart along a second direction perpendicular to the first direction, and the two limiting members 61 abut against both sides of the resistor 100 respectively. The clamping member 62 is spaced apart from the two limiting members 61 along the first direction, and the clamping member 62 is used to clamp the end of the resistor 100 away from the free end 120, and can release the resistor 100 during the process of the resistor 100 being attached to the base 200. It is understood that the two limiting members 61 are located on top of the bearing surface 121, and the two limiting members 61 and the bearing surface 121 can form a limiting groove for accommodating the resistor 100, so as to limit the resistor 100 along the second direction. After the resistor 100 is placed in the limiting groove, the end of the resistor 100 away from the free end 120 is clamped by the clamping member 62 to limit the resistor 100 along the first direction. After the adhesive 110 is attached to the base 200, the clamping member 62 can release the resistor, thereby preventing the resistor 100 from being completely limited during the bonding process.

[0071] For example, the resistor 100 is provided with a lug 130 perpendicular to the free end 120 at one end away from the free end 120. The clamping member 62 includes a linear cylinder and a shift fork. The shift fork is disposed at the piston rod end of the linear cylinder and can be pushed towards the lug 130 by the linear cylinder. The shift fork limits the lug 130 on both sides along the first direction.

[0072] In this embodiment, the locking part 2 includes a turntable 21 and a locking member 22. The turntable 21 is disposed at the rotating end of the rotating part 3 and can rotate around the axis of the turntable 21. The outer peripheral wall of the turntable 21 is provided with a receiving groove 211 adapted to the base 200. The locking member 22 covers the outside of the receiving groove 211 and is used to lock the base 200 inside the receiving groove 211. The locking member 22 is provided with a clearance groove for avoiding the attachment path of the resistor 100. It can be understood that the curvature of the outer peripheral wall of the turntable 21 is consistent with the curvature of the base 200. After the base 200 is placed in the receiving groove 211, the locking member 22 is fixed to the turntable 21 by bolts or other fixing structures. The locking member 22 locks the edge of the base 200, thereby preventing the base 200 from falling out of the receiving groove 211. The locking element 22 is arc-shaped, and the inner wall of the arc-shaped locking element 22 can fit against the outer peripheral wall of the turntable 21 to ensure the stability of the base 200 under force when locking the base 200.

[0073] Furthermore, the free end 120 is provided with a positioning hole 1210; the outer peripheral wall of the turntable 21 is provided with a positioning pin 212 adapted to the positioning hole 1210, and the positioning pin 212 is spaced apart from the starting end 210. It can be understood that during the rotation of the turntable 21, the positioning pin 212 can be inserted into the positioning hole 1210 to realize the positioning of the turntable 21 and the resistor, thereby further ensuring the attachment accuracy of the resistor during the attachment process.

[0074] In addition, the rotating part 3 includes a frame, a rack 31, a gear 32, and a drive shaft 33. The frame is spaced apart from the bearing part 1 along the second direction. The rack 31 is arranged on the frame along the first direction and meshes with the gear 32. The gear 32 is fixed on the drive shaft 33. One end of the drive shaft 33 is rotatably arranged on the connecting plate, and the other end is fixedly connected to the turntable 21. The turntable 21, the drive shaft 33, and the gear 32 are arranged coaxially. When the drive shaft 33 moves with the connecting plate, under the meshing action of the gear 32 and the rack 31, the drive shaft 33 can be driven to rotate along its own axis, thereby driving the turntable 21 to rotate.
