Referring to fig. 6 and fig. 7 together, fig. 6 is a schematic structural diagram of a manual driving component of the lifting driving mechanism in the embodiment; fig. 7 is an isometric cross-sectional view of the manual drive member of fig. 6.
The drive unit 300 of the manually driven lift drive mechanism is shown in detail in fig. 6 and 7.
In a specific scheme, a first mounting seat 340 is detachably and fixedly connected to a first bracket 324, and the brake module is mounted on the first mounting seat 340 and is matched with the driving shaft 322 to lock and unlock the driving shaft 322. The setting of first mount pad 340 makes things convenient for the installation of different brake modules, can not need set up different mounting structure on first support 324 because of the structure difference of brake module. Of course, in actual setting, the brake module may be directly mounted on the first bracket 324.
Specifically, when the manually driven lifting driving mechanism is used for lifting and driving the ball tube assembly, the ball tube assembly is mounted on the sliding seat 200, and at this time, the brake module mounted on the first mounting seat 340 is a first brake module corresponding to the ball tube assembly.
In this embodiment, the first brake module is specifically an electrified electromagnetic brake 400a, and when the electrified electromagnetic brake 400a is installed, the turntable of the electrified electromagnetic brake 400a is fixedly connected with the driving shaft 322, and the base of the electrified electromagnetic brake 400a is fixedly connected with the first mounting seat 340, that is, the turntable of the electrified electromagnetic brake 400a can rotate along with the driving shaft 322.
When in use, after the electrified electromagnetic brake 400a is electrified, the turntable is attracted with the base, and the base is fixedly connected with the first bracket 324 through the first mounting seat 340, so that the turntable is fixed at this time, thereby limiting the rotation of the driving shaft 322 and further keeping the position of the sliding seat 200 provided with the bulb assembly fixed; when the electrified electromagnetic brake 400a is powered off, the turntable is disengaged from the base, and at this time, the turntable is not fixed and can freely rotate with the driving shaft 322.
In this embodiment, the electrified electromagnetic brake 400a is used to realize the lifting movement of the sliding seat 200 in emergency situations, such as system power failure. It will be appreciated that in actual setting, other brakes with the same effect may be selected, or other brakes may be selected according to different requirements.
When the manual lifting driving mechanism for the ball tube assembly works, the electrified electromagnetic brake 400a is powered off, the turntable of the manual lifting driving mechanism is disconnected from the base, the driving shaft 322 is in a rotatable state, the manual lifting ball tube assembly can drive the sliding seat 200 provided with the ball tube assembly to vertically lift along the upright post 100, a driving pair formed by the driving shaft 322, the driving wheel 321 and the main driving belt 323 can drive the driving shaft 322 to rotate under the action of the balance force of the balancing weight 600, and meanwhile, the driven shaft 332 is driven to rotate through a driving pair formed by the driven shaft 332, the driven wheel 331 and the auxiliary driving belt 333; when the ball tube assembly is lifted to a required position, the electrified electromagnetic brake 400a is electrified through operation to lock the driving shaft 322, so that the driving shaft 322 cannot rotate, and the ball tube assembly is fixed at the required position for corresponding operation; if the position of the ball and socket assembly is to be adjusted later, the electrified electromagnetic brake 400a is powered off, the drive shaft 322 is unlocked, and the ball and socket assembly is lifted manually to adjust the position of the ball and socket assembly.
When the manually driven lifting driving device lifts and drives the bulb assembly, loads of the main driving belt 323 and the auxiliary driving belt 333 act on the driving shaft 322 and the driven shaft 332 respectively, and no matter which shaft fails in the process, no harm is caused to operators or equipment, so that the safety is high.
Specifically, when the manually driven lifting driving mechanism is used for lifting and driving the vertical imaging assembly, the vertical imaging assembly is mounted on the sliding seat 200, and at this time, the brake module mounted on the first mounting seat 340 is a second brake module corresponding to the vertical imaging assembly.
In this embodiment, the second brake module is specifically an electric-loss electromagnetic brake 400b, and when in installation, a turntable of the electric-loss electromagnetic brake 400b is fixedly connected with the driving shaft 322, and a base of the electric-loss electromagnetic brake 400b is fixedly connected with the first mounting seat 340, that is, the turntable of the electric-loss electromagnetic brake 400b can rotate along with the driving shaft 322.
When the power-off electromagnetic brake 400b is in use, after the power-off electromagnetic brake is powered off, the turntable is attracted to the base, and the base is fixedly connected with the first bracket 324 through the first mounting seat 340, so that the turntable is fixed at this time, thereby limiting the rotation of the driving shaft 322, and further keeping the position of the sliding seat 200 mounted with the vertical imaging assembly fixed; when the electromagnetic brake 400b is powered on, the turntable is disengaged from the base, and at this time, the turntable is not fixed and can freely rotate with the driving shaft 322.
In this embodiment, the power-off electromagnetic brake 400b is adopted, so that it is ensured that when the system is powered off and an imaging flat plate is not placed in the chest box of the vertical imaging component installed on the sliding seat 200, the chest box cannot generate lifting movement due to unbalance with the counterweight, and safety can be ensured. It will be appreciated that in actual setting, other brakes with the same effect may be selected, or other brakes may be selected according to different requirements.
When the manual lifting driving mechanism for the vertical imaging assembly works, the power-off electromagnetic brake 400b is electrified, the turntable is separated from the base, the driving shaft 322 is in a rotatable state, the manual lifting vertical imaging assembly can drive the sliding seat 200 provided with the vertical imaging assembly to vertically lift along the upright post 100, a driving pair formed by the driving shaft 322, the driving wheel 321 and the main driving belt 323 can drive the driving shaft 322 to rotate under the action of the balance force of the balancing weight 600, and meanwhile, the driven shaft 332 is driven to rotate through a driving pair formed by the driven shaft 332, the driven wheel 331 and the auxiliary driving belt 333; when the vertical imaging assembly is lifted to a required position, the electromagnetic brake 400b with power failure is powered off by operation to lock the driving shaft 322, so that the driving shaft 322 cannot rotate, and the vertical imaging assembly is fixed at the required position for corresponding operation; if the position of the vertical imaging assembly is to be adjusted later, the de-energized electromagnetic brake 400b is energized to unlock the drive shaft 322, and then the vertical imaging assembly is manually lifted to adjust the position of the vertical imaging assembly.
In actual setting, the type of the power-off electromagnetic brake 400b is selected, so that the moment generated by the braking force of the power-off electromagnetic brake 400b is larger than the moment generated by the self weight of the imaging plate, and after the power-off electromagnetic brake 400b is powered off to lock the driving shaft 322, whether the flat panel detector of the vertical imaging assembly is arranged in the wafer box or not, the sliding seat 200 is kept in a static state, so that the operator is not damaged, and the equipment is not damaged; after the system is powered off, the power-off electromagnetic brake 400b is powered off, the driving shaft 322 is in a locking state, the sliding seat 200 is kept static, no harm is caused to operators, and no damage is caused to equipment.

It can be understood that when the lifting driving mechanism drives the sliding seat 200 to move up and down, the position of the sliding seat 200 is related to the rotation parameter of the driven shaft 332, the rotation shaft of the rotary potentiometer 510 rotates along with the driven shaft 332, and the detection parameter can reflect the position change of the sliding seat 200, so that the relative position of the sliding seat 200 can be determined according to the output value.
In a specific setting, a reference point may be selected, and a correspondence between the output value of the rotary potentiometer 510 and the position of the slide base 200 may be determined according to the mutual conversion between the structural parameters.
More specifically, the position feedback module further includes a mounting plate 520 and a limiting rod 530, wherein the rotary potentiometer 510 is mounted on the mounting plate 520, a clamping groove 521 matched with the limiting rod 530 is provided on the mounting plate 520, the limiting rod 530 is fixedly connected to a second bracket 334, and after assembly, the limiting rod 530 is clamped in the clamping groove 521 of the mounting plate 520.
Thus, when the lifting drive mechanism is operated, the body of the rotary potentiometer 510 is ensured not to rotate, and only the rotating shaft thereof rotates along with the driven shaft 332.
In actual arrangement, the mounting plate 520 may have a hole structure that cooperates with the stop lever 530, in addition to the slot 521.
The working process of the manual lifting driving mechanism with the position feedback function provided in this embodiment is similar to that described in the previous embodiment, and is not repeated, except that the position feedback module is added, so that the relative position of the sliding seat 200 can be accurately determined according to the position feedback module during specific operation.

In actual setting, the driving motor 350 may also be directly fixed to the first bracket 324 through the motor mounting plate 360, that is, the second mounting seat 370 is not provided; however, in view of installation space and convenience of operation, it is preferable to provide the second mounting seat 370, particularly, the second mounting seat 370 and the motor mounting plate 360 with through holes corresponding to the positions of the driving shaft 322 so that the output shaft of the driving motor 350 is coupled with the driving shaft 322, and more particularly, both sides of the second mounting seat 370 may be provided with protruding portions, which may be respectively inserted into the through holes of the first bracket 324 and the through holes of the motor mounting plate 360 to ensure coaxiality of the output shaft of the driving motor 350 and the driving shaft 322.
In this embodiment, the arrangement of the brake module, the structure and arrangement of the position feedback module, etc. are the same as those in the foregoing embodiment, and will not be described herein.
It should be noted that, the height value of the sliding seat 200 from the installation ground (the relative position of the sliding seat 200) is related to the spindle rotation number of the driving motor 350, the corresponding relationship between the position parameter of the sliding seat 200 and the proportional relationship between the spindle rotation number of the driving motor 350 and the output value of the rotary potentiometer 510 may be determined in advance, and in actual operation, the position of the sliding seat 200 is determined according to the output value of the rotary potentiometer 510.
Of course, the position of the sliding seat 200 may be determined only according to the number of rotations of the spindle of the driving motor 350 or the output value of the rotary potentiometer 510 in actual setting, but the judgment is more accurate by the proportional relationship between the two, so that erroneous judgment due to a failure (as mentioned later) can be avoided.
When the lifting driving device driven by the driving motor 350 is used for lifting and driving the ball tube assembly, the ball tube assembly is mounted on the sliding seat 200, and at this time, the brake module mounted on the first mounting seat 340 is specifically the electrified electromagnetic brake 400a.
When the electrified electromagnetic brake 400a is powered off, the driving shaft 322 is in a rotatable state, the driving motor 350 is started to rotate, the driving shaft 322 is driven to rotate, the sliding seat 200 provided with the ball tube assembly is driven to vertically lift along the upright post 100, and it can be understood that the lifting of the sliding seat 200 is controlled by the forward and backward rotation of the driving motor 350; meanwhile, the driven shaft 332 rotates along with the rotation of the rotary potentiometer 510 connected with the driven shaft 332, the output value of the rotary potentiometer 510 changes along with the position change of the sliding seat 200, the lifting position of the sliding seat 200 can be determined according to the output value of the rotary potentiometer 510 and the rotating speed of the driving motor 350, when the sliding seat 200 drives the ball tube assembly to reach the required position, the driving motor 350 is controlled to stop, and meanwhile, the electrified electromagnetic brake 400a is electrified to stop driving the driving shaft 322 and lock the position of the driving shaft 322.
When the lifting driving device driven by the driving motor 350 is used for lifting and driving the vertical imaging assembly, the vertical imaging assembly is mounted on the sliding seat 200, and at this time, the brake module mounted on the first mounting seat 340 is specifically the power-off electromagnetic brake 400b.
When the electromagnetic brake 400b is powered on, the driving shaft 322 is in a rotatable state, the driving motor 350 is started to rotate, the driving shaft 322 is driven to drive, the sliding seat 200 provided with the vertical imaging assembly is driven to vertically lift along the upright post 100, and it can be understood that the lifting of the sliding seat 200 is controlled by the positive and negative rotation of the driving motor 350; meanwhile, the driven shaft 332 rotates, the rotary potentiometer 510 connected with the driven shaft 332 rotates along with the rotation, the lifting position of the sliding seat 200 can be determined according to the output value of the rotary potentiometer and the rotation speed of the driving motor 350, when the sliding seat 200 drives the vertical imaging component to reach a required position, the driving motor 350 is controlled to stop, and meanwhile, the power-off electromagnetic brake 400b is powered off, so that the driving of the driving shaft 322 is stopped and the position of the driving shaft 322 is locked.
In a further scheme, when the driving motor 350 is used as a driving source, the tension of the main driving belt 323 can be adjusted to be smaller than that of the auxiliary driving belt 333, so that after the arrangement, when the lifting driving mechanism works, the abrasion of the auxiliary driving belt 333 is larger than that of the main driving belt 323, so that the auxiliary driving belt 333 can fail before the main driving belt 323, if the auxiliary driving belt 333 breaks and fails in the working process, the main driving belt 323 can ensure that the sliding seat 200 provided with the bulb assembly or the vertical imaging assembly is still under the balance force of the balancing weight 600; at this time, the driving motor 350 still drives the driving shaft 322 to rotate, and the auxiliary driving belt 333 does not drive the driven shaft 332 to rotate due to failure, so that the rotary potentiometer 510 does not rotate, and thus the output value of the rotary potentiometer 510 does not change due to the position change along with the sliding seat 200, and at this time, the proportional relationship between the output value of the rotary potentiometer 510 and the rotation speed of the driving motor 350 is incorrect, so that the system can be judged to have a fault.
In addition, when the rotation potentiometer 510 fails during operation of the elevating drive mechanism, the proportional relationship between the output value and the rotation speed of the drive motor 350 is also incorrect.
Specifically, a controller may be disposed, and the controller is in communication connection with the rotary potentiometer 510 and the driving motor 350, and may receive a feedback signal of the rotary potentiometer 510 and a rotation speed signal of the driving motor 350, determine whether a ratio relationship between the feedback signal and the rotation speed signal is correct, and send an alarm signal when the ratio relationship between the feedback signal and the rotation speed signal is incorrect, and after knowing the alarm information, a worker may stop to perform maintenance to determine whether the auxiliary driving belt 333 breaks or the rotary potentiometer 510 fails.
It should be noted that in each of the above illustrated embodiments, the main belt 323 and the auxiliary belt 333 are both in the form of a chain, and it is understood that, in actual arrangement, both may be designed as belts or other forms.
The manual lifting driving mechanism with position feedback and electric lifting driving mechanism is introduced, and when in actual setting, different modules can be assembled according to actual situations, so that the requirements of various product configurations are met, and the modularized design is also beneficial to upgrading of the existing products.
