Description

Technical Field

[0001] The utility model relates to the field of rotating target untying equipment, in particular to a tailstock mechanism of a rotating target untying device and a rotating target untying device. Background Technique

[0002] During the production of ITO rotating targets, the residual targets or unqualified bonded targets need to go through the untying process. During the untying process, the rotating target needs to rotate continuously to ensure uniform rotation and stable heating of the target. However, since the target is in the shape of a long cylinder, one end of the target is fixed to the rotating shaft of the untying machine through a flange, and the other end uses a tailstock to clamp the rotating target. Among them, the center point needs to be adjusted to be coaxial and concentric with the target and the rotating shaft, and the center point is advanced and tightened against the target by manually rotating the rocker. When the center point is tightened, manual operation is required. When different employees operate, it is difficult to grasp the tightening force. When it is too loose, there is a risk of the target falling off during rotation. When it is too tight, the friction between the center point and the back tube is too large, which is likely to damage the center point and the target.

[0003] CN112725743A discloses a target cylinder untying device, including a bottom plate and a first vertical plate. The bottom plate and the first vertical plate are connected together, and the bottom plate and the first vertical plate are perpendicular to each other and form an L shape; a slide rail is arranged on the top surface of the bottom plate, and a slide table bracket slidably matched with the slide rail is arranged on the slide rail. A first clamping rotating shaft for fixing one end of the target cylinder is arranged on the slide table bracket, and a first motor for controlling the rotation of the first clamping rotating shaft is arranged at the end of the first clamping rotating shaft away from the target cylinder; a second clamping rotating shaft for fixing the other end of the target cylinder is arranged at the center of the top surface of the first vertical plate. The target cylinder is placed between the first clamping rotating shaft and the second clamping rotating shaft, and a heater is arranged at the lower end of the target cylinder. A support cylinder for controlling the lifting of the heater is arranged between the heater and the bottom plate. For this target cylinder untying device, different lengths of targets can be stably untied through the motor drive principle, and the solder layer can be recycled to avoid waste of the solder layer. The first clamping rotating shaft is immovable on the slide table bracket, and the first clamping rotating shaft is pressed against the target by relying on the second motor to drive the slide table bracket to move, which may cause the pre-tightening force received by the target to be inconsistent each time.

[0004] The technical problem to be solved by the utility model is: how to ensure that the pre-tightening force of clamping the target each time is the same and avoid damaging the center point and the rotating target. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a tailstock mechanism of a rotating target untying device. By setting the position of the limiting module, the compression amount of the elastic module is controlled, so as to control the elastic force of the elastic module, and further control the pre-tightening force between the center point and the rotating target, so as to achieve the same pre-tightening force for clamping the target each time.

[0006] At the same time, a rotating target untying device is also provided.

[0007] To achieve the above object, the technical solution adopted in the present application is as follows:

[0008] A tailstock mechanism of a rotary target untying device, comprising a frame, a first driving unit and a tightening unit arranged on the frame. The tightening unit includes a center point, a support platform, an elastic module and a limit module; the support platform is slidably connected to the frame; a smooth shaft is provided at the rear end of the center point; the smooth shaft is movably connected to the support platform; the elastic module is sleeved on the smooth shaft; the limit module is arranged on the support platform;

[0009] When the first driving unit drives the support platform to move and drives the center point to contact the rotary target, the elastic module is compressed, and the smooth shaft moves towards the limit module until the smooth shaft contacts the limit module.

[0010] Preferably, a bearing seat is provided on the support platform; the smooth shaft is movably connected to the bearing seat; both ends of the elastic module respectively abut against the rear end of the center point and the inner ring of the bearing seat.

[0011] Preferably, the support platform includes a moving seat and a lifting module; the moving seat is slidably connected to the frame; the lifting module is arranged on the moving seat; the bearing seat is arranged on the lifting module; the limit module is arranged on the lifting module.

[0012] Preferably, the lifting module includes a lifting platform and a driving component; the driving component is arranged on the moving seat; the power output end of the driving component is connected to the lifting platform; the bearing seat is arranged on the lifting platform; the limit module is arranged on the lifting platform.

[0013] Preferably, the elastic module is a spring, an elastic sheet or a gas spring.

[0014] Preferably, the limit module is a roller type travel switch or a proximity switch.

[0015] Meanwhile, a rotary target untying device is also provided, including the tailstock mechanism as described in any one of the above, a rotating shaft, a second driving unit for driving the rotating shaft to rotate, and a heating unit for heating the rotary target; the rotating shaft is rotatably connected to the frame.

[0016] Preferably, the heating unit includes an internal heating module and an external heating module; the internal heating module is sleeved on the rotating shaft; the external heating module is arranged at the bottom of the frame.

[0017] Compared with the prior art, the present solution has the following beneficial effects:

[0018] For the tailstock mechanism of this case, the optical axis of the center can rotate and slide on the support platform. By sleeving an elastic module on the optical axis, during the process of the center pressing against the rotating target, the center is subjected to the pressure of the rotating target, thereby compressing the elastic module. At the same time, the elastic module provides a pre-tightening force for the center. After the center stops moving, the elastic module can provide a stable pre-tightening force, thus maintaining the stability of the pre-tightening force.

[0019] Secondly, by setting a limiting module, after the center contacts the rotating target and continues to move forward, the optical axis moves backward and the elastic module is compressed. When the optical axis touches the limiting unit, the center stops moving, so that each time the rotating target is clamped, the compression amount of the elastic module is the same, thereby ensuring that the pre-tightening force for each clamping is the same.

Detailed Embodiments

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Usually, the components of the present application implemented described and illustrated in the drawings here can be arranged and designed in various different configurations.

[0024] Embodiment 1

[0025] Refer to Figure 1-2 , a tailstock mechanism of a rotating target untying device, including a frame 1, a first driving unit 3 arranged on the frame 1, and a tightening unit 2. The tightening unit 2 includes a center 21, a support platform 24, an elastic module 22, and a limiting module 23; the support platform 24 is slidably connected to the frame 1; the rear end of the center 21 is provided with an optical axis 211; the optical axis 211 is movably connected to the support platform 24; the elastic module 22 is sleeved on the optical axis 211; the limiting module 23 is arranged on the support platform 24;

[0026] When the first driving unit 3 drives the support platform 24 to move and drives the center point 21 to contact the rotating target, the elastic module 22 is compressed, and the optical axis 211 moves towards the limiting module 23 until the optical axis 211 contacts the limiting module 23.

[0027] In this embodiment, the specific working process of the tailstock mechanism is as follows: The first driving unit 3 drives the support platform 24 to move towards the rotating target, thereby driving the center point 21 to contact the rotating target. The first driving unit 3 continues to drive the center point 21 to move towards the rotating target, and the center point 21 starts to tightly hold the rotating target. Due to the pressure of the rotating target on the center point 21, the center point 21 drives the optical axis 211 to move backward, thereby compressing the elastic module 22. When the end of the optical axis 211 contacts the limiting module 23, the first driving unit 3 stops working, and the optical axis 211 no longer moves. At this time, the center point 21 tightly holds the rotating target.

[0028] It should be noted that by arranging the elastic module 22 on the optical axis 211, when the first driving unit 3 drives the center point 21 to move and tightly hold the rotating target, the pre-tightening force of the center point 21 on the rotating target is maintained by the elastic force of the elastic module 22. In this way, not only can the same pre-tightening force be better maintained, but also the damage to the center point 21 and the rotating target can be avoided. By further arranging the limiting module 23, when the end of the optical axis 211 contacts the limiting module 23, the first driving unit 3 stops working, so that the tightening distance of the center point 21 is the same each time, and the compression amount of the elastic module 22 is the same, thus ensuring that the pre-tightening force of the center point 21 is the same each time. By changing the position of the limiting module 23, the pre-tightening force of the center point 21 can be easily adjusted.

[0029] The first driving unit 3 is a lead screw motor.

[0030] Preferably, the support platform 24 is provided with a bearing seat 11; the optical axis 211 is movably connected to the bearing seat 11; both ends of the elastic module 22 respectively abut against the rear end of the center point 21 and the inner ring of the bearing seat 11.

[0031] In this embodiment, there is a clearance fit between the optical axis 211 and the bearing seat 11, and the optical axis 211 can rotate and slide on the bearing seat 11. The use of the bearing seat 11 can reduce the wear of the optical axis 211 and improve its service life. One end of the elastic module 22 abuts against the rear end of the center point 21, and the other end abuts against the inner ring of the bearing seat 11. After the center point 21 tightly holds the rotating target, the center point 21 and the elastic module 22 rotate together with the rotating target, and the elastic module 22 abuts against the inner ring of the bearing seat 11 without relative sliding with the bearing seat 11.

[0032] Preferably, the support platform 24 includes a moving seat 242 and a lifting module 241; the moving seat 242 is slidably connected to the frame 1; the lifting module 241 is disposed on the moving seat 242; the bearing seat 11 is disposed on the lifting module 241; the limiting module 23 is disposed on the lifting module 241.

[0033] In this embodiment, by providing the lifting module 241, it is possible to meet the use of rotating targets with different diameters. When the diameter of the rotating target changes, the height of the top 21 is adjusted by the lifting module 241 so that the top 21 and the rotating target are on the same axis, so that the top 21 can stably rotate following the rotating target.

[0034] Preferably, the lifting module 241 includes a lifting platform 2411 and a driving component 2412; the driving component 2412 is disposed on the moving seat 242; the power output end of the driving component 2412 is connected to the lifting platform 2411; the bearing seat 11 is disposed on the lifting platform 2411; the limiting module 23 is disposed on the lifting platform 2411.

[0035] In this embodiment, the driving component 2412 is a cylinder. The driving component 2412 drives the lifting platform 2411 to move up and down, thereby driving the top 21 to move up and down, so that the top 21 and the rotating target are on the same axis, so that the top 21 can stably rotate following the rotating target.

[0036] Preferably, the elastic module 22 is a spring, an elastic sheet or a gas spring.

[0037] In this embodiment, the elastic module 22 is preferably a spring and can also be selected according to actual circumstances.

[0038] Preferably, the limiting module 23 is a roller type travel switch or a proximity switch.

[0039] In this embodiment, the limiting module 23 is preferably a roller type travel switch and can also be selected according to actual circumstances. The manufacturer of the roller type travel switch is Omron, and the model is WLCA12-2N-N.
