Description

Technical Field

[0001] This invention relates to a separable balancing unit, and more particularly to a separable balancing unit that, by forming a load-transfer component and a balancing component separately, changes the contact position of the load-transfer component and the balancing component in real time when operating a supported object such as a machine head, thereby adjusting the magnitude of the elastic force used to maintain the rotational balance of the articulated arm and the length of the moment arm. Background Technology

[0002] The articulated arm is equipped with a column component fixed to a support base such as a laser oscillator or a worktable, and multiple rods connected in a manner that allows for up-down and left-right rotation relative to the column component via joints. The end of the articulated arm is used to support an instrument, such as a dental treatment head.

[0003] To reduce user fatigue, the articulated arm needs to be supported in a way that allows the user to freely manipulate the machine head with minimal force.

[0004] Figure 1 It is a perspective view of the articulated arm equipped with the existing balancing unit.

[0005] Next, please refer to Figure 1 Please provide an explanation.

[0006] By utilizing the weight of the support object 20, the rod 30, and the joint 40, which are arranged on the right side with the column component 10 as a reference, the support object 20 will sag downwards and receive rotational torque. In order to prevent the support object 20 from sag downwards as described above, a torque in the opposite direction to the torque on one side of the support object needs to be applied to the joint arm.

[0007] To address this, a balancing unit is proposed to maintain the rotational balance of the articulated arm.

[0008] exist Figure 1 In the existing balancing unit shown in the figure, in order to generate a torque in the opposite direction to the torque on one side of the supported object, the user needs to adjust the size and position of the counterweight 50.

[0009] However, when the user moves the support object 20, the magnitude of the torque on the support object changes in real time. In order to maintain rotational balance, there is a cumbersome problem that the user needs to change the size and position of the counterweight 50 at any time.

[0010] Furthermore, changing the size and position of the counterweight 50 requires interrupting operations, which reduces ease of use.

[0011] Therefore, there is an urgent need to develop a new type of balancing unit that can apply torque in the opposite direction to maintain rotational balance in real time without interrupting the operation when the user moves the supporting object 20.

[0042] Next, please refer to Figures 2 to 6 Please provide an explanation.

[0043] The present invention relates to a balancing unit for maintaining the rotational balance of a joint arm, which is constructed by combining a plurality of rods 30, joints 40 and support objects 20 into a column member 10 arranged in a vertical direction and fixed to a specific support member, by applying a torque in the opposite direction to the torque relative to one side of the support object 20 with reference to the column member 10.

[0044] The balancing unit according to the present invention includes a load transfer component 100 and a balancing component 200.

[0045] Figure 7 This is a perspective view of the load transfer component 100 according to the present invention. Figure 8 This is a front oblique view of the lifting platform 220 according to the present invention. Figure 9 This is a rear oblique view of the lifting platform 220 according to the present invention, and Figure 10 This is a perspective view of the outer casing 210 according to the present invention.

[0046] Next, please refer to Figures 7 to 10 Please provide an explanation.

[0047] The load transfer component 100 is disposed between the rod 31 adjacent to the column component and the main body component 10.

[0048] One side of the load transfer component 100 is fixed to the rod 31 adjacent to the column component, while the other side is connected to the upper end of the column component 10 in a manner that allows it to rotate in opposite directions up and down.

[0049] The rotation axis relative to the rod 31 adjacent to the column component and the load transmission component 100 is Figure 6 The symbol is represented by X.

[0050] Therefore, the load transfer component 100 and the rod 31 adjacent to the column component will work together with Figure 6 The rotation axis X in the diagram is used as a reference for vertical rotation.

[0051] The load transfer component 100 is formed in a ring shape and has a roller 110 rotatably attached to its end.

[0052] The roller 110 contacts the balancing member 200, which will be described later, and can roll relative to the balancing member 200. This reduces friction between the load transfer member 100 and the balancing member 200.

[0053] The balancing component 200 is fixed to one side of the column component 10 in a manner distinct from the load transfer component 100.

[0054] The balancing component 200 is configured to disengage from the load transfer component 100 and transmit torque in the opposite direction to the rotation direction of the load transfer component 100.

[0055] The term "separate type" in the name of this invention, "separate type balancing unit," refers to the separation of the load transfer component 100 from the balancing component 200.

[0056] In the existing balancing unit, the load transfer component is integrated with the counterweight 50, so it is impossible to maintain rotational balance in real time. In order to adjust the size and position of the counterweight 50, the user needs to interrupt the operation and perform the adjustment operation of the counterweight 50 manually.

[0057] Therefore, in this invention, while separating the load transfer component 100 and the balancing component 200, a rolling motion is performed between the two components via the roller 110, and an elastic force is applied to the balancing component 200, enabling real-time and automatic rotational balancing without interrupting the operation. That is, when the torque on one side of the supported object 20 changes in real time, the load transfer component 100 moves relative to the balancing component 200, thereby automatically adjusting the magnitude of the torque in the opposite direction.

[0058] Next, the detailed configuration of the present invention used to achieve the described function will be described.

[0059] The balancing component 200 according to the present invention includes a housing 210, a lifting platform 220, and an elastic component 230.

[0060] The housing 210 forms a space around its outer periphery and inside. Furthermore, the housing 210 has an opening on one side and one or more guide rails 211 are formed on the inner side of the component on the other side.

[0061] The lifting platform 220 has a guide rail receiving groove 221 formed on its rear side, and the guide rail 211 is inserted into the guide rail receiving groove 221, thereby moving along the guide rail 211.

[0062] The elastic component 230 is a structure that applies an elastic force to the lifting platform 220.

[0063] One end of the elastic component 230 is fixed to the lifting platform 220, and the other end is fixed to the housing 210.

[0064] In this way, when the lifting platform 220 moves along the guide rail 211, the load transmission component 100 is subjected to the elastic force that changes by means of the elastic component 230.

[0065] The elastic component 230 may be one or more selected from spring 231, damper 232, piston and cylinder assembly.

[0066] exist Figure 6 In the middle, two springs 231 are combined on the front of the lifting platform 220, and a damper 232 is combined on the back. However, it is not limited to this, but can be adjusted to the required elastic modulus by deforming into various forms.

[0067] like Figure 7 As shown, a support base 223 for supporting the spring 231 can be provided on the front of the lifting platform 220.

[0068] In addition, a guide bracket 222 with one side curved can be provided on the front of the lifting platform 220.

[0069] As the roller 110 of the load transfer assembly rolls along the curved surface of the guide bracket 222, the contact position will change, and therefore the elastic force formed by the elastic component 230 will also change accordingly.

[0070] Figure 11 This is a schematic diagram used to illustrate the working principle of the balancing unit according to the present invention.

[0071] exist Figure 11 The process of the load transfer assembly rotating counterclockwise is illustrated in the order of (a), (b), and (c).

[0072] As the load transfer assembly rotates counterclockwise, the roller 110 moves along the curved surface and pushes the lifting platform 220 upward. Because the guide rail 211 is inserted into the guide rail receiving slot 221 of the lifting platform 220, the lifting platform 220 will move in the vertical direction.

[0073] Furthermore, because the lifting platform 220 incorporates an elastic component 230, namely a spring 231 or a damper 232, the elastic force formed by the spring 231 and the damper 232 will increase as the lifting platform 220 moves upward.

[0074] exist Figure 11 During the process from (a) to (c), the rotation angle of the load transfer component 100 in the counterclockwise direction gradually increases, which means that the torque on one side of the supported object 20 increases. Therefore, in order to maintain rotational balance, the torque in the opposite direction should also increase accordingly.

[0075] Next, we will focus on... Figure 11 The principle of torque increasing in the opposite direction during the process from (a) to (c) will be explained.

[0076] Torque is calculated by multiplying the magnitude of the torque by the length of the torque arm.

[0077] exist Figure 11In this context, the length of the torque arm is represented by L.

[0078] It can be confirmed that Figure 11 During the process from (a) to (c), the length of the torque arm gradually increases, and it can be confirmed that the elastic component 230 will be further compressed when the lifting platform 220 moves upward, thereby increasing the magnitude of the elastic force.

[0079] Furthermore, it can be confirmed that the compression of the elastic component changes along the curved shape of the guide bracket, thereby providing a variety of reaction forces.

[0080] As described above, the balancing unit according to the present invention can automatically apply a torque in the opposite direction to the load transfer member 100, which rotates together with the rod 31 adjacent to the main body, when the torque on one side of the support object 20 changes in real time due to the user moving the support object 20 around, thereby achieving rotational parallelism.

[0081] Conversely, the magnitude of the reverse torque depends on the elastic force of the elastic component 230, determined by the position of the guide bracket 222, multiplied by the length of the torque arm.

[0082] In this invention, the user does not need to interrupt the operation and manually perform the adjustment of the counterweight 50 in order to maintain rotational balance while moving the support object 20. Instead, the magnitude of the elastic force and the length of the torque arm can be changed automatically, thereby solving the existing problems.

[0083] As a result, users can maintain the rotational balance of the articulated arm during operation, thereby completing the task with minimal force.

[0084] Figure 12 This is a perspective view of an articulated arm equipped with a balancing unit according to another embodiment of the present invention.

[0085] It is joined to the housing 210 in the vertical direction Figure 2 The joints of the arms are different, in Figure 12 On the articulated arm shown in the figure, the outer shell 210 is joined along the horizontal direction.

[0086] However, in Figure 12 The working principle of the articulated arm shown in the figure is similar to that in... Figure 2 The articulated arm shown in the figure works on the same principle.

[0087] This invention relates to a separable balancing unit, and more particularly to a separable balancing unit that, by forming a load transfer component 100 and a balancing component 200 separately, changes the contact position of the load transfer component 100 and the balancing component 200 in real time when operating a support object 20 such as a machine head, thereby adjusting the magnitude of the elastic force used to maintain the rotational balance of the joint arm and the length of the torque arm.

[0088] In the foregoing, preferred embodiments of the present invention have been illustrated and described. However, the present invention is not limited to the specific embodiments described above. Instead, various modifications can be made by those skilled in the art without departing from the spirit of the invention as claimed in the claims. These modifications should not be construed as independent of the technical concept or prospect of the present invention.
