Technical Field
[0001] This invention belongs to the technical field of wire harness processing equipment, and relates to a positioning, clamping and rotating device for wire harness heat shrink tubing. Background Technology
[0002] In existing wire harness processing, a rotating mechanism is often needed to turn the wire harness, which is fitted with heat shrink tubing, to facilitate subsequent processes such as heat shrink tubing assembly. Currently, rotary cylinders or motors are commonly used to directly drive the clamping jaws holding the wire harness for rotation and turning. However, this method has significant drawbacks: firstly, the position of the heat shrink tubing lacks effective constraint during rotation and handover, making it prone to accidentally entering the clamping area of the jaws and being damaged, resulting in product scrap; secondly, the wire harness itself has a certain weight, and during handover between different mechanisms, it is prone to downward displacement due to gravity, causing the jaws to be unable to clamp accurately or to clamp skewed, affecting processing efficiency and product quality. Therefore, there is an urgent need for a rotating device that can achieve precise positioning of the heat shrink tubing and stable clamping of the wire harness to solve the above problems.

[0029] The present invention will be further described below with reference to the accompanying drawings.
[0030] like Figure 1-11As shown, a wire harness heat shrink tubing positioning and clamping rotation device is characterized by comprising an X-axis linear motor 1, a transfer rotation mechanism 2, and a top-loading rotation mechanism 8. The X-axis linear motor 1 is provided with a first moving base 11 and a second moving base 12. The transfer rotation mechanism 2 is fixedly connected to the first moving base 11, and the top-loading rotation mechanism 8 is fixedly connected to the second moving base 12. The X-axis linear motor 1 drives the transfer rotation mechanism 2 and the top-loading rotation mechanism 8 to move along the X-axis direction through the first moving base 11 and the second moving base 12, respectively. The transfer and rotation mechanism 2 includes a base plate 13, a Y-axis guide rail 14, a Y-axis slider 35, a lead screw nut fixing seat 34, a closed-loop stepper motor 3, a motor flange plate 32, a lead screw 33, a Z-axis guide rail 36, a Z-axis slider 41, a bracket 42, a Z-axis cylinder 44, a bearing 43, a rotating shaft 51, a connecting plate 52, a pad 53, a clamping cylinder 54, a piston push block 541, a guide block 542, a gripper 55, a control clamp 71, a top material cylinder 63, a spherical bearing, and an equal-height bolt 65. The top material rotation mechanism 8 includes a base plate 13, a Y-axis guide rail 14, a Y-axis slider 35, a lead screw nut fixing seat 34, a closed-loop stepper motor 3, a motor flange plate 32, a lead screw 33, a Z-axis guide rail 36, a Z-axis slider 41, a bracket 42, a Z-axis cylinder 44, a bearing 43, a rotating shaft 51, a connecting plate 52, a pad 53, a clamping cylinder 54, a piston push block 541, a guide block 542, a gripper 55, a wire gathering arm 72, a tube blocking cylinder 74, a fixing plate 73, and a heat shrink tubing baffle 75.
[0031] Furthermore, the first side of the base plate 13 is fixedly connected to the first moving part seat 11, the second side of the base plate 13 is fixedly connected to the Y-axis guide rail 14, the Y-axis guide rail 14 is slidably connected to the Y-axis slider 35, and the Y-axis slider 35 is fixedly connected to the lead screw nut fixing seat 34; the closed-loop stepper motor 3 is fixedly connected to the motor flange plate 32, the motor flange plate 32 is fixedly connected to the Y-axis guide rail 14 in the first plane direction and in the second plane direction, and the first plane direction and the second plane direction are perpendicular to each other; the output end of the closed-loop stepper motor 3 is connected to the lead screw 33, and the lead screw 33 is engaged with the lead screw nut in the lead screw nut fixing seat 34.
[0032] In this embodiment, the lead screw nut fixing seat 34 is securely connected to the Y-axis slider 35 by bolts or other fasteners, ensuring that it will not loosen or shift during movement. When the closed-loop stepper motor 3 starts, its output end drives the lead screw 33 to rotate. The rotational motion of the lead screw 33 is converted into the linear motion of the lead screw nut, which in turn drives the lead screw nut fixing seat 34 and the connected Y-axis slider 35 to perform precise linear reciprocating motion along the Y-axis guide rail 14.
[0033] Furthermore, a Z-axis guide rail 36 is fixedly provided on the lead screw nut fixing seat 34 along the Z-axis direction. The Z-axis guide rail 36 is slidably connected to the sliding surface of the Z-axis slider 41. The fixed surface of the Z-axis slider 41 away from the sliding surface is fixedly connected to the bracket 42. The bracket 42 is provided with a first mounting part 421 and a second mounting part 422. The two Z-axis sliders 41 are fixedly connected to the first mounting part 421 and the second mounting part 422 respectively.
[0034] In this embodiment, the Z-axis slider 41 is tightly fitted with the sliding surface of the Z-axis guide rail 36, enabling precise movement along the Z-axis direction. The bracket 42, through its fixed connection to the Z-axis slider 41, can move along with the Z-axis slider 41 in the Z-axis direction. The first mounting part 421 and the second mounting part 422 can mount different components according to actual needs, with the two Z-axis sliders 41 fixedly connected to them respectively, ensuring stable support and precise movement of the components mounted on these mounting parts in the Z-axis direction.
[0035] Furthermore, the Z-axis cylinder 44 is fixedly connected to the bracket 42. The piston rod of the Z-axis cylinder 44 is provided with a groove 441, and the lead screw nut fixing seat 34 is provided with a slot 341. The groove 441 and the slot 341 are connected to restrict the Z-direction displacement of the piston rod of the Z-axis cylinder 44. The lead screw nut fixing seat 34 is fixedly provided with a rubber head limiting screw 424, and the bracket 42 is fixedly provided with a first stop pin 342. The rubber head limiting screw 424 and the first stop pin 342 are correspondingly arranged.
[0036] In this embodiment, after the Z-axis cylinder 44 is fixedly connected to the bracket 42, the groove 441 on its piston rod is tightly engaged with the slot 341 on the lead screw nut fixing seat 34, which effectively restricts the displacement of the piston rod of the Z-axis cylinder 44 in the Z direction and ensures the stability of the equipment during operation.
[0037] Furthermore, the bracket 42 is provided with a bearing mounting hole 423, the outer ring of the bearing 43 is fixedly connected to the bearing mounting hole 423, the inner ring of the bearing 43 is fixedly connected to the rotating shaft 51, the end of the rotating shaft 51 protruding from the bearing 43 is fixedly connected to the connecting plate 52, the connecting plate 52 is fixedly connected to the pad 53, and the pad 53 is fixedly connected to the clamping cylinder 54.
[0038] In this embodiment, by providing a bearing mounting hole 423 on the bracket 42 and fixing the outer ring of the bearing 43 to the mounting hole, a stable installation of the bearing 43 on the bracket 42 is achieved. Simultaneously, the fixed connection between the inner ring of the bearing 43 and the rotating shaft 51 allows the rotating shaft 51 to rotate flexibly relative to the bracket 42.
[0039] Furthermore, the output end of the clamping cylinder 54 is connected to the piston push block 541, and the guide block 542 is provided with a guide groove. The piston push block 541 is slidably engaged with the guide groove. The piston push block 541 is drivenly connected to the gripper 55, and the gripper 55 is fixedly connected to the control clamp 71. The outer shell of the top material cylinder 63 extends out a rotating shaft, which is embedded in the mounting hole of the bracket 42. The piston rod of the top material cylinder 63 is fixedly connected to the outer ring 641 of the spherical bearing, and the inner ring 642 of the spherical bearing is engaged with the equalizing bolt 65. The equalizing bolt 65 is fixedly connected to the connecting plate 52.
[0040] In this embodiment, the piston push block 541 is smoothly moved by connecting the output end of the clamping cylinder 54 to the piston push block 541 and the guide groove on the guide block 542 through the sliding cooperation between the piston push block 541 and the guide groove. Then, the gripper 55 is driven to perform a precise clamping action through the transmission connection, and finally the control clamp 71 completes the stable clamping of the target object.
[0041] Furthermore, a second rubber head limiting screw 522 and a second stop pin 521 are fixedly provided on the connecting plate 52, and a limiting block 62 is fixedly provided on the bracket 42. The limiting block 62 is provided with a rubber head limiting screw, the second stop pin 521 is correspondingly provided with the rubber head limiting screw on the limiting block 62, and the second rubber head limiting screw 522 is correspondingly provided with the limiting block 62.
[0042] In this embodiment, by setting a second rubber head limiting screw 522 and a second stop pin 521 on the connecting plate 52, and setting a limiting block 62 with a rubber head limiting screw on the bracket 42, and making the second stop pin 521 correspond to the rubber head limiting screw on the limiting block 62, and the second rubber head limiting screw 522 correspond to the limiting block 62, it can play a precise limiting and stopping role during the operation of the equipment, and effectively prevent the relative position between the connecting plate 52 and the bracket 42 from deviating.
[0043] Furthermore, the gripper 55 is fixedly connected to the wire gathering arm 72, the guide block 542 is fixedly connected to the tube blocking cylinder 74 through the fixing plate 73, the output end of the tube blocking cylinder 74 is connected to the blocking arm, the blocking arm is connected to the heat shrink tubing baffle 75, and the tube blocking cylinder 74 drives the blocking arm to rotate, causing the heat shrink tubing baffle 75 to move closer or further away from each other.
[0044] In this embodiment, by fixing the gripper 55 to the wire gathering arm 72, the gripper 55 can clamp the target object while the wire gathering arm 72 can organize and gather the wires around the target object. The output end of the tube-blocking cylinder 74 is connected to the blocking arm, which is then connected to the heat shrink tubing baffle 75. When the tube-blocking cylinder 74 drives the blocking arm to rotate, it can cause the heat shrink tubing baffles 75 to move closer or further apart. Thus, the position of the heat shrink tubing baffles 75 can be flexibly adjusted according to actual needs to meet the processing requirements of target objects of different specifications.
[0045] Furthermore, the outer ring 641 of the spherical bearing rotates relative to the inner ring 642 of the spherical bearing, and the top material cylinder 63 drives the connecting plate 52 to rotate around the rotating shaft 51 through the extension and retraction of the piston rod.
[0046] In this embodiment, the relative rotational design between the outer ring 641 and the inner ring 642 of the spherical bearing makes the connecting plate 52 more stable and flexible during rotation, reducing friction and resistance during rotation and improving the operating efficiency and stability of the equipment. The top-loading cylinder 63 drives the connecting plate 52 to rotate around the rotating shaft 51 through the extension and retraction of the piston rod, realizing automated rotation control of the connecting plate 52, and can precisely adjust the position and angle of the connecting plate 52 according to the operating requirements of the equipment.
[0047] The working principle of this invention is: When the wire harness 91 enters the processing flow and needs to be turned around, the X-axis linear motor 1 is started. The first moving base 11 and the second moving base 12 respectively drive the transfer rotation mechanism 2 and the top material rotation mechanism 8 to move to a suitable position on the X-axis. The transfer rotation mechanism 2 starts working, and the piston rod of the Z-axis cylinder 44 retracts, driving the bracket 42 to move upward along the Z-axis guide rail 36 to a predetermined position. At this time, the clamping cylinder 54 drives the piston push block 541 to reciprocate within the guide groove of the guide block 542, forcing the grippers 55 to rotate and move closer together, thereby clamping the wire harness 91. Simultaneously, the control clamp 71 synchronously clamps the heat shrink tubing 92, preventing the heat shrink tubing 92 from accidentally entering the clamping area and being damaged.
[0048] Then, the top-loading cylinder 63 of the transfer rotation mechanism 2 extends its piston rod, pushing the connecting plate 52 to rotate, thereby causing the gripper 55 to rotate 90° counterclockwise, so that the wire harness 91 is in the same direction as the X-axis. At the same time, the top-loading cylinder of the top-loading rotation mechanism 8 retracts its piston rod, driving the connecting plate to rotate, causing the gripper to rotate 90° clockwise. Then, the X-axis linear motor 1 drives the top-loading rotation mechanism 8 to move to the left through the second moving base 12. During the leftward movement, the tube-blocking cylinder 74 drives the heat shrink tubing baffle 75 to close, resisting any possible movement of the heat shrink tubing 92 to the left, preventing the heat shrink tubing 92 from shifting and being damaged. At the same time, the wire-gathering arm 72, under the closing tendency of the gripper 55, preferentially contacts the wire harness 91, lifting the wire harness 91 that has shifted downward due to gravity to the clamping area, and clamping the wire harness 91 after the gripper 55 closes. Then, the X-axis linear motor 1 drives the top-loading rotation mechanism 8 to move to the right and reset through the second moving base 12. After resetting, the gripper 55 and control clamp 71 of the transfer rotation mechanism 2 release the wire harness 91 and heat shrink tubing 92. Finally, the ejector cylinder of the ejector rotation mechanism 8 extends its piston rod, pushes the connecting plate to rotate, and drives the gripper to rotate 90° counterclockwise, completing the wire harness reversal operation, so that the wire harness at the front end can be smoothly fitted with heat shrink tubing, and continue the subsequent processing.
