DETAILED DESCRIPTION

[0031] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0032] like Figures 1 to 3 As shown, a finger sleeve plugging and unplugging device includes a base 1, a control box 2, a Z-axis lifting mechanism 3, a Y-axis moving mechanism 4, and a plugging and unplugging mechanism 5. The base 1 provides stable support for the device as a whole. The control box 2 is slidably set on the base 1 and slides horizontally along the base 1. The control elements installed in the control box 2 provide intelligent guidance for the operation of the device. The control elements in the controller can use a single-chip microcomputer. The Z-axis lifting mechanism 3 is vertically set on the control box 2, and the Y-axis moving mechanism 4 is slidably set on the Z-axis lifting mechanism 3 and slides up and down along the Z-axis lifting mechanism 3. The plugging and unplugging mechanism 5 is horizontally slidably set on the Y-axis moving mechanism 4, and slides horizontally along the Y-axis moving mechanism 4, and slides up and down along the Z-axis lifting mechanism 3 together with the Y-axis moving mechanism 4.

[0033] like Figure 4The plug-in mechanism 5 includes a bracket 50, an upper roller assembly 51 and a lower roller assembly 52 respectively arranged on the bracket 50, and a clamping assembly 53 respectively arranged at both ends of the bracket 50. A plug-in gap 54 is formed between the upper roller assembly 51 and the lower roller assembly 52. ​​The plug-in gap 54 corresponds to the clamping cavity 533 of the clamping assembly 53. The bracket 50 is arranged on the Y-axis moving mechanism. After the finger sleeve is clamped by the clamping assembly 53, the plug-in mechanism 5 and the finger sleeve are driven to move as a whole by the Y-axis moving mechanism. After moving to the designated position, the finger sleeve is moved horizontally and pulled out by the roller assembly. In this process, the position sensor 55 arranged on the outer side of the clamping assembly 53 detects the position of the finger sleeve joint. When the finger sleeve joint is detected, the position sensor 55 transmits the detection signal to the controller. The controller controls the upper roller assembly 51 and the lower roller assembly 52 to work, and then drives the finger sleeve to perform plug-in and pull-out operations.

[0034] The upper roller assembly 51 and the lower roller assembly 52 both include a driving motor 510, a transmission assembly, and a plurality of rollers 511. The transmission assembly is connected to the output end of the driving motor 510, and transmits power to the rollers 511 through the transmission assembly. A plug-in gap 54 is formed between the rollers 511 of the upper roller assembly 51 and the rollers 511 of the lower roller assembly 52. ​​The transmission assembly can adopt a belt and pulley structure, and the pulley is coaxially arranged with the roller 511. When the driving motor 510 is started, the power is transmitted to the rollers 511 through the belt and pulley. The rollers 511 rotate, and the finger sleeves are driven to move under the action of friction, thereby realizing the plug-in and pull-out operation of the finger sleeves.

[0035] In addition, the clamping assembly 53 includes an upper clamping block 530 and a lower clamping block 531 respectively arranged on the bracket 50, and clamping grooves 532 are respectively provided on the upper clamping block 530 and the lower clamping block 531, and a clamping cavity 533 is formed between the clamping groove 532 of the upper clamping block 530 and the clamping groove 532 of the lower clamping block 531. In order to improve the smoothness of the plugging and unplugging operation, a guide wheel 56 for guiding the finger sleeve is also rotatably provided on the bracket 50. In addition, since the finger sleeve is long, in order to avoid bending during the plugging and unplugging transmission process, in the present invention, an arc-shaped support platform 57 for supporting the finger sleeve is provided between the clamping cavity 533 and the plugging and unplugging gap 54, and the arc-shaped support platform 57 provides support for the finger sleeve to avoid bending deformation caused by uneven force.

[0036] like Figure 5As shown, the Z-axis lifting mechanism 3 includes a support plate 30, a first motor 31, a first screw rod 32 and a first screw seat 33. The support plate 30 is vertically arranged on the control box 2, the first motor 31 is arranged on the support plate 30, the first screw rod 32 is matched and connected to the output end of the first motor 31, the first screw seat 33 is slidably arranged on the support plate 30 and matched and connected to the first screw rod 32, the first screw rod 32 drives the first screw seat 33 to move along the support plate 30, and the Y-axis moving mechanism 4 is arranged on the first screw seat 33. The driving motor 510 is connected to the controller for communication, the first screw rod 32 is connected to the output shaft of the driving motor 510 through a coupling or a sleeve, and the other end of the first screw rod 32 is connected to the support plate 30 through a bearing. The outer surface of the first screw rod 32 is provided with external helical teeth, and the interior of the first screw seat 33 is provided with a through hole, and the through hole is provided with internal helical teeth matching the external helical teeth. During operation, the driving motor 510 is started to drive the first screw rod 32 to rotate, and then drives the first screw seat 33 matched on the first screw rod 32 to move, thereby driving the Y-axis moving mechanism 4 set on the first screw seat 33 to move up and down.

[0037] In order to improve the stability of the Y-axis moving mechanism 4 sliding along the Z-axis lifting mechanism 3, in the present invention, first slide rails 34 are respectively provided at both ends of the support plate 30, and first slide seats 35 slidably matched with the first slide rails 34 are provided at both ends of the horizontal plate 40 of the Y-axis moving mechanism 4. Through the support sliding on both sides, the stability of the sliding process is effectively improved to avoid tilting or shaking during sliding.

[0038] The Y-axis moving mechanism 4 includes a horizontal plate 40, a second motor 41, a second screw rod 42 and a second screw seat 43. The horizontal plate 40 is horizontally arranged on the first screw seat 33. The second motor 41 is arranged on the horizontal plate 40. The second screw rod 42 is connected to the output end of the second motor 41. The second screw seat 43 is slidably arranged on the horizontal plate 40 and connected to the second screw rod 42. The second screw rod 42 drives the second screw seat 43 to move along the horizontal plate 40. The plug-in mechanism 5 is arranged on the second screw seat 43. The working principle of the Z-axis lifting mechanism 3 is the same. The second motor 41 drives the second screw rod 42 to rotate, thereby driving the second screw seat 43 to move, thereby driving the horizontal movement of the plug-in mechanism 5. In addition, in order to improve the stability of movement, second slide rails 44 are arranged on both sides of the horizontal plate 40, and the plug-in mechanism 5 is provided with a second slide seat 45 that slides and cooperates with the second slide rails 44.

[0039] In order to improve the smoothness of the overall movement of the device along the X-axis, such as Figure 6As shown, in the present invention, third slide rails 10 are provided on both sides of the base 1, wherein the third slide rail 10 on one side is provided with continuous gear teeth 11, the gear teeth 11 are meshed with a driving gear 12 provided at the bottom of the control box 2, and the driving gear 12 is driven by a third motor 14 provided in the control box 2; the third slide rail 10 on the other side is matched and connected with a third slide seat 13, and the third slide seat 13 is provided at the bottom of the control box 2. The third motor 14 drives the driving gear 12 to rotate, the gear meshes with the gear teeth 11 on the slide rail, and drives the control box 2 to move along the slide rail in the reverse direction, thereby realizing the overall movement of the control box 2 and the components on the control box 2 through the forward and reverse rotation of the third motor 14.

[0040] In order to improve the working stability of the equipment, in the present invention, a plurality of auxiliary positioning blocks are provided on both side end faces of the base 1, and the base 1 is positioned by the auxiliary positioning blocks.
