[0059] The utility model discloses a preferred embodiment, and combining with the drawings more clearly and completely explains the utility model.
[0060] The embodiment provides a scalp tensioning device 100, and the specific structure is as shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 And Figure 6 The scalp tensioning device 100 is arranged on the hair transplantation chair 200, and the scalp tensioning device 100 comprises:
[0061] Contact part 10 is used for contacting with the scalp;
[0062] Driving part 20 is arranged on the hair transplantation chair 200, and the driving part 20 is electrically connected with the control module (not shown in the figure) of the hair transplantation chair 200, and the driving part 20 is used to drive the contact part 10 to tension or loosen the hair follicle extraction area of the scalp;
[0063] Adjusting mechanism 30 is arranged on the hair transplantation chair 200, and the adjusting mechanism 30 is used to drive the driving part 20 to rotate, so that the contact part 10 corresponds to the position of the scalp.
[0064] Specifically, the contact part 10 is configured as a plate and connected to one end of the driving part 20, and the other end of the driving part 20 can be preferably arranged on the mounting plate 201 of the hair transplantation chair 200, and the contact part 10 is driven by the driving part 20 to approach or move away from the user's scalp, thereby realizing the tensioning of the hair follicle extraction area of the scalp. It can be understood that the driving part 20 drives the contact part 10 to perform the extension and contraction motion through the signal sent by the control module, and the working principle is the prior art, which will not be described in detail here. By arranging the contact part 10 and driving the contact part 10 to move through the driving part 20 to replace the way of tensioning the scalp by the silica gel rope, the tensioning of the user's scalp is realized, the tensioning degree is ensured, and compared with the traditional way of manually tensioning the silica gel rope by hand, the degree of automation is higher, the manual operation is reduced, the tensioning accuracy of the scalp can be greatly improved, the situation that bacteria is transmitted to the scalp due to the frequent contact of the operator's hand with the user's scalp can be reduced, and the frequent switching between the sterile and unsterile environments can be prevented from the root.
[0065] In addition, the adjusting mechanism 30 can be preferably arranged on the mounting plate 201 of the hair transplantation chair 200, and the adjusting mechanism 30 can be used to drive the driving part 20 to rotate, so that the angle between the contact part 10 and the scalp changes, that is, to ensure that the contact part 10 can better adapt to the user's scalp. The adjusting mechanism 30 can be arranged at the connection between the driving part 20 and the mounting plate 201, or arranged on one side of the driving part 20, and the driving part 20 is rotationally connected with the mounting plate 201 and driven by the adjusting mechanism 30 to rotate around the mounting plate 201. For example, the adjusting mechanism 30 can be a manual rocker structure, or a driving motor in the prior art, to drive the driving part 20 to rotate. By arranging the adjusting mechanism 30 to drive the driving part 20 to rotate, the driving part 20 can maintain a suitable tensioning angle when driving the contact part 10 to tension the scalp, so as to avoid the user feeling strong pain, thereby improving the user's experience.
[0066] Further, in the embodiment, the scalp tensioning device 100 further comprises a vision system (not shown in the figure), which is electrically connected with the control module, and the driving part 20 and / or the adjusting mechanism 30 are moved through the vision data of the vision system.
[0067] Specifically, the hair transplantation chair 200 has an operation head (not shown in the figure), and the operation head has a visual function to facilitate the operator to identify the specific parameter information of the user's scalp through the operation head. In the embodiment, the visual system and the operation head can preferably share the same lens, so as to transmit the identified visual data to the control module through the visual system, and control the movement of the driving part 20 through the control module, thereby driving the contact part 10 to move and tension the hair follicle extraction area of the user's scalp. It is not necessary to make a judgment manually, and the additional lens is reduced, thereby reducing the manufacturing cost of the scalp tensioning device 100. When the adjusting mechanism 30 is a driving motor, the driving motor is electrically connected with the control module to receive signals from the control module. The visual system is used to transmit signals to the control module to adjust the angle between the driving part 20 and the mounting plate 201, and the driving part 20 is close to or away from the user's scalp, so as to drive the contact part 10 to move and tension the user's scalp.
[0068] It can be understood that the additional visual system replaces the traditional way of manually judging whether the scalp is tensioned in place. Compared with manual judgment, the visual data is more accurate, so as to automatically tension the scalp and automatically tension to the position to maintain the tension of the scalp, further improve the accuracy of automatically tensioning the scalp, reduce the manual operation steps, and improve the use convenience.
[0069] In the embodiment, the scalp tensioning device 100 further comprises a force feedback mechanism (not shown in the figure), which is arranged on the driving part 20. The force feedback mechanism is electrically connected with the control module. When the scalp is tensioned, the driving part 20 maintains the tensioning state of the scalp through the force feedback mechanism.
[0070] Specifically, the force feedback mechanism can be a force sensor or a pressure sensor in the prior art. The force feedback mechanism is arranged on the driving part 20, so that when the force feedback from the scalp to the contact part 10 and the driving part 20 increases and reaches a preset value during the process that the driving part 20 drives the contact part 10 to tension the scalp, the force feedback mechanism sends a signal to the control module to stop the driving part 20 from continuing to tension the scalp and maintain the tensioning state of the scalp. That is, the force feedback mechanism can timely prompt the control module that the tensioning is in place, and maintain the tensioning state of the driving part 20 through the control module, without manual operation, and the automation degree is higher. It can be understood that the working principle of the force feedback mechanism and the control module is the prior art, and the embodiment does not improve it, and will not be described in detail here.
[0071] In other embodiments, the stop of the driving part 20 from continuing to tension the scalp and the maintenance of the tensioning state of the hair follicle extraction area of the scalp can also be achieved by a manual feedback mode. Specifically, a locking mechanism can be arranged to lock the driving part 20 when the visual data of tensioning in place is obtained through the visual system. The locking mechanism is a structure in the prior art, and will not be described in detail here.
[0072] Of course, the visual system can also be cancelled, and the tensioning of the hair follicle extraction area of the scalp can be determined manually. Specifically, manual alignment can be performed before hair transplantation, and then the contact portion 10 can be driven by the driving portion 20 to automatically tension the hair follicle extraction area of the scalp during actual operation.
[0073] In this embodiment, the driving portion 20 includes a first driving assembly 21, a second driving assembly 22, and a third driving assembly 23 connected in sequence. The first driving assembly 21 drives the second driving assembly 22 and the third driving assembly 23 to move along the Z-axis direction of the coordinate system. The second driving assembly 22 drives the third driving assembly 23 to move along the Y-axis direction of the coordinate system. The third driving assembly 23 drives the contact portion 10 to move along the X-axis direction of the coordinate system.
[0074] Specifically, the first driving assembly 21 is arranged at the connection between the driving portion 20 and the mounting plate 201, and the connection is used as the Z-axis of the coordinate system. The first driving assembly 21, the second driving assembly 22, and the third driving assembly 23 are connected in sequence. The first driving assembly 21 is arranged perpendicularly to the second driving assembly 22. The first driving assembly 21, the second driving assembly 22, and the third driving assembly 23 can each move in an extendable and retractable manner to adjust the position of the contact portion 10 corresponding to different axes of the coordinate system. That is, the first driving assembly 21 drives the second driving assembly 22 and the third driving assembly 23 to move along the Z-axis direction, thereby adjusting the position of the contact portion 10 connected to the third driving assembly 23 along the Z-axis direction. The adjusting mechanism 30 can be arranged on the first driving assembly 21 or between the first driving assembly 21 and the mounting plate 201. By driving the first driving assembly 21 to rotate, the second driving assembly 22, the third driving assembly 23, and the contact portion 10 can be driven to move closer to or farther away from the scalp of the user. It can be understood that the first driving assembly 21, the second driving assembly 22, and the third driving assembly 23 can be cylinders, hydraulic cylinders, or oil cylinders in the prior art.
[0075] Similarly, the second driving assembly 22 is arranged perpendicularly to the first driving assembly 21 and along the Y-axis direction of the coordinate system. Since the second driving assembly 22 can move in an extendable and retractable manner, the third driving assembly 23 connected in sequence to the second driving assembly 22 can drive the contact portion 10 to adjust the position along the Y-axis direction. Further, the third driving assembly 23 is arranged perpendicularly to the second driving assembly 22 and along the X-axis direction of the coordinate system. Since the third driving assembly 23 can move in an extendable and retractable manner, the contact portion 10 connected to the third driving assembly 23 can adjust the position along the X-axis direction. By driving the contact portion 10 to move along different directions of the coordinate system, the scalp can be finally tensioned, and the tensioning can be avoided from being not in place due to the contact portion being unable to move along a certain direction.
[0076] It should be noted that the coordinate system is realized by modeling in the prior art, and in the embodiment, the modeling can be realized by the visual system, or the movement along the coordinate system can be realized by sequentially connecting and perpendicularly arranging the first driving assembly 21, the second driving assembly 22, and the third driving assembly 23, taking the mounting plate 201 as the reference, to realize the tensioning operation in different directions of the scalp.
[0077] Further, in the embodiment, the adjusting mechanism 30 is arranged on the first driving assembly 21, the adjusting mechanism 30 is electrically connected with the control module, the first driving assembly 21 comprises a first driving motor 211, a first output shaft 212, and a first guide shaft 213, the first output shaft 212 and the first guide shaft 213 extend from the first driving motor 211, and the first output shaft 212 and the first guide shaft 213 are arranged in parallel, the second driving assembly 22 is arranged on the first output shaft 212 and the first guide shaft 213, and the second driving assembly 22 is driven by the first output shaft 212 and moves along the Z-axis direction of the coordinate system.
[0078] Specifically, the first driving motor 211 is arranged along the Z-axis direction of the coordinate system, the first driving motor 211 can be a rectangular or cylindrical structure, the first output shaft 212 and the first guide shaft 213 are arranged in parallel from the end surface of the first driving motor 211, and the other ends of the first output shaft 212 and the first guide shaft 213 are provided with the adjusting mechanism 30, the adjusting mechanism 30 is a driving motor in the prior art, that is, the two ends of the first output shaft 212 and the first guide shaft 213 are respectively provided with the adjusting mechanism 30 and the first driving motor 211, and a rotating shaft 31 is further arranged below the first output shaft 212 and the first guide shaft 213, the two ends of the rotating shaft 31 are respectively connected with the adjusting mechanism 30 and the first driving motor 211, the rotating shaft 31 is used to be rotationally connected with the mounting plate 201, the driving motor is used to drive the rotating shaft 31 to rotate, so as to realize the rotation of the first driving assembly 21 around the mounting plate 201, and further realize the adjustment of the angle between the driving part 20 and the mounting plate 201.
[0079] It can be understood that the first driving motor 211 and the first output shaft 212 can be a servo motor driving screw rod movement in the prior art, one end of the second driving assembly 22 is arranged on the first output shaft 212 and the first guide shaft 213, so as to drive the second driving assembly 22 to move along the Z-axis direction of the coordinate system when the first output shaft 212 rotates, and the first guide shaft 213 is arranged in parallel with the first output shaft 212, and the movement of the second driving assembly 22 along the Z-axis direction of the coordinate system guides the second driving assembly 22, so as to prevent the deviation of the second driving assembly 22 from causing the poor precision of the automatic tensioning of the scalp.

[0082] It can be understood that the second driving motor 221 and the second output shaft 222 can be a mode that a servo motor drives a lead screw to move in the prior art, which is the prior art and will not be described in detail here.
[0083] In other embodiments, the force feedback mechanism can be arranged on the second driving assembly 22, specifically on the second driving motor 221, so as to feedback whether the head is tensioned by whether the action force of the head being tensioned transmitted from the contact part 10 to the third driving assembly 23, the second output shaft 222 and the second guide shaft 223 reaches a preset value, without artificial judgment, and the automation degree is higher. When the head is in the tensioning state, the first driving assembly 21, the second driving assembly 22 and the third driving assembly 23 are closed by the control module, so as to keep fixed at different axial positions in the coordinate system, and then keep the position of the contact part 10 unchanged, thereby realizing the function of keeping the tensioning degree of the head.
