Description

Technical Field

[0001] The present application relates to a linear guide rail, and more particularly to an assembly method of a guide rail frame. Background Art

[0002] In the field of linear guide technology, the slider slides along the guide rail through the ball bearings. The guide rail frame is used for ball bearing reversal, so that the ball bearings can achieve cyclic motion. The guide rail frame of the related art has many components and a complex structure, so the assembly process of the guide rail frame is complicated and cumbersome, and the assembly efficiency is low. Summary of the invention

[0003] In view of this, the present application provides an assembly method of a guide rail frame to improve assembly efficiency.

[0004] An embodiment of the present application provides a method for assembling a guide rail frame. The method for assembling a guide rail frame includes:

[0005] Select the force application position on the guide rail frame;

[0006] Applying a force to the force application position to elastically deform the elastic deformation area of ​​the guide rail frame, so that the two rotating frames of the guide rail frame move away from each other;

[0007] The guide rail frame is moved to a set position, and the force is withdrawn to cause the elastic deformation area to rebound, so that the two rotating frames clamp the slide block.

[0008] In the above embodiment, by determining the force application position, the possibility that the force applied to other positions of the guide rail frame cannot drive the elastic deformation area to deform elastically is reduced, and the magnitude of the force required to elastically deform the elastic deformation area is reduced. Through the elastic deformation of the elastic deformation area, the relative position of the partial structure of the guide rail frame is changed, thereby driving the two rotating frames to deform or move, and the two rotating frames are opened so that the relative distance between the two rotating frames increases, thereby allowing the slider to enter between the two rotating frames. The guide rail frame is moved to a set position so that the slider is between the two rotating frames. After the force is withdrawn, the elastic deformation area lacking the external force will rebound, thereby reducing the relative distance between the two rotating frames until it abuts against the opposite sides of the slider, and the guide rail frame is relatively fixed to the slider under the action of its own elastic force to achieve assembly. Through the above assembly method, the guide rail frame's own elastic deformation ability is utilized to automatically clamp the guide rail frame to the slider to complete the assembly, which also saves the process of assembling multiple components of the guide rail frame with each other, thereby simplifying the assembly steps and improving the assembly efficiency.

[0009] In some embodiments of the present application, each rotating frame and a guide rail frame are connected to an elastic structure to form an elastic deformation area.

[0010] The step of selecting a force application position in the elastic deformation area of ​​the guide rail frame comprises:

[0011] The force application locations are located at the two elastic structures.

[0012] The step of applying a force to the force application position to elastically deform the elastic deformation area of ​​the guide rail frame includes:

[0013] Applying forces to the two elastic structures causes the two elastic structures to elastically deform.

[0014] In the above embodiment, the force acts directly on the elastic structure, causing the elastic structure to stably produce elastic deformation, thereby driving the rotating frame connected to the elastic structure to deform or move, thereby improving the stability of the spreading action that moves the two rotating frames away from each other, which is beneficial to improving the success rate of assembly, thereby reducing the time wasted due to assembly failure and helping to improve assembly efficiency.

[0015] In some embodiments of the present application, each elastic structure is provided with a connection hole. The guide rail frame assembly method further includes: providing an assembly mechanism.

[0016] The step of applying a force to the two elastic structures to elastically deform the two elastic structures comprises:

[0017] The assembly mechanism extends into the connecting hole of each elastic structure and applies a force to each elastic structure, and the directions of the forces applied to the two elastic structures are opposite to each other.

[0018] In the above embodiment, the assembly mechanism extends into the connection hole and applies a force to the elastic structure, thereby improving the stability of the connection between the assembly structure and the elastic structure, thereby enhancing the stability of the force applied to the elastic structure. The assembly mechanism applies a force to elastically deform the two elastic structures in a direction away from each other, thereby driving the respective connected rotating frames away from each other. The direction of the force application is consistent with the direction of deformation or movement of the rotating frames, and the assembly action is continuous, which facilitates improving assembly efficiency.

[0019] In some embodiments of the present application, each rotating frame and a guide rail frame are connected to an elastic structure to form an elastic deformation area.

[0020] The step of selecting a force application position in the elastic deformation area of ​​the guide rail frame comprises:

[0021] The force application point is located at the two rotating frames.

[0022] The step of applying a force to the force application position to elastically deform the elastic deformation area of ​​the guide rail frame includes:

[0023] Applying force to the two rotating frames causes the two elastic structures to elastically deform.

[0024] In the above embodiment, the force applied to the rotating frame is transmitted to the elastic structure connected to the rotating frame to cause the elastic structure to deform elastically, thereby causing the two rotating frames to move away from each other. The force is directly applied to the rotating frame, so that after the force changes, the position of the rotating frame can be changed in time, thereby improving the accuracy of the position of the two rotating frames moving away from each other. On the one hand, the possibility of damage to the guide frame due to excessive deformation or displacement of the rotating frame is reduced, and on the other hand, it is easier to ensure that the distance between the two rotating frames can be set to the slider. This is conducive to improving the success rate of assembly, thereby reducing the time wasted due to assembly failure, and is conducive to improving assembly efficiency.

[0025] In some embodiments of the present application, the guide rail frame assembly method further includes: providing an assembly mechanism, which includes a mechanical arm.

[0026] The step of applying a force to the force application position to elastically deform the elastic deformation region comprises:

[0027] The robot arm applies a force to the force application position to elastically deform the elastic deformation area.

[0028] The step of moving the guide rail frame to a set position comprises:

[0029] The robot arm moves the guide frame to the set position.

[0030] In the above embodiment, the force is applied to the force application position by the mechanical arm, which improves the accuracy of the position and size of the force application, and is conducive to improving the assembly efficiency. After the mechanical arm opens the two rotating frames, the rebound tendency of the elastic deformation area enables the guide rail frame to be relatively fixed to the mechanical arm, so that it is convenient for the mechanical arm to drive the guide rail frame to move. By moving the guide rail frame by the mechanical arm, it is convenient to improve the accuracy of the guide rail frame moving to the set position, which is conducive to accurately moving the two rotating frames to the two sides of the slider. In addition, the structure of opening the two rotating frames and the structure of positioning the guide rail frame and the slider are integrated into the mechanical arm, and the assembly of the guide rail frame can be achieved by controlling the mechanical arm, which simplifies the assembly steps and is conducive to improving the assembly efficiency.

[0031] In some embodiments of the present application, the assembly mechanism further includes a pressure sensing component. The pressure sensing component is disposed on the mechanical arm.

[0032] The mechanical arm applies a force to the force application position, including:

[0033] The robot arm applies a gradually increasing force to the force application position until the pressure sensing component detects that the force is equal to the set pressure, and the robot arm maintains the set pressure to elastically deform the elastic deformation area.

[0034] In the above embodiment, the pressure sensing element is used to reduce the possibility of the robot arm applying too much force to the force application position, reduce the possibility of direct damage to the guide rail frame or the elastic deformation area failing to rebound smoothly, thereby improving assembly efficiency.

[0035] In some embodiments of the present application, the assembly mechanism further includes a displacement sensing component.

[0036] The mechanical arm applies a force to the force application position to elastically deform the elastic deformation area, including:

[0037] The mechanical arm applies a gradually increasing force to the force application position until the displacement sensing component detects that the distance between the two rotating frames is equal to the set distance, and the mechanical arm maintains the force to elastically deform the elastic deformation area.

[0038] In the above embodiment, the displacement sensing element is used to reduce the possibility of excessive deformation or displacement of the rotating frame, reduce the possibility of direct damage to the guide rail frame or failure of the elastic deformation area to rebound smoothly, thereby improving assembly efficiency.

[0039] In some embodiments of the present application, the assembly mechanism further includes a pressing member.

[0040] The step of moving the guide rail frame to a set position comprises:

[0041] The pressing piece presses the guide rail frame toward the slide.

[0042] In the above embodiment, the guide rail frame is pressed by the pressing member so that the guide rail frame and the slider are relatively fixed, which is beneficial to improve the accuracy of the position of the two rotating frames clamping the slider, improve the success rate of assembling the guide rail frame to the slider, and help improve assembly efficiency.

[0043] In some embodiments of the present application, the assembly mechanism further includes a fixing member. The fixing member is arranged at a set position.

[0044] The guide rail frame assembly method also includes:

[0045] Before the robot arm moves the guide rail frame to the set position, the slide block is fixed to the fixing member.

[0046] In the above embodiment, the slider can be fixed to a set position by a fixing member, so that the robot arm can determine the position of the slider, thereby improving the accuracy of the robot arm in assembling the guide rail frame to the slider.

[0047] In some embodiments of the present application, the evacuation force causes the elastic deformation area to rebound, including:

[0048] The force applied by the robot arm is released to allow the elastically deformed area to rebound.

[0049] In the above embodiment, the force applied by the robotic arm is released, so that the robotic arm actively stops driving the elastic deformation area to deform elastically. By controlling the robotic arm, the opening action of the two rotating frames and the assembly action of the rotating frame clamping slider can be realized, which simplifies the control logic of the assembly mechanism and is conducive to improving assembly efficiency.

[0050] The guide rail frame assembly method of the present application determines the force application position and applies the force to the force application position, so that the elastic deformation area is deformed, thereby the two rotating frames are spread apart, so as to facilitate the setting of the slider between the two rotating frames. The two rotating frames clamp the slider by utilizing the rebound of the elastic deformation area, thereby completing the assembly of the guide rail frame and the slider. The assembly steps are simplified and the assembly efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0083] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0084] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0085] In the description of the present application, it should be noted that the terms "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0086] Furthermore, the terms “first,” “second,” “third,” etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

[0087] An embodiment of the present application provides a method for assembling a guide rail frame. The method for assembling a guide rail frame includes:

[0088] Select the force application position on the guide rail frame;

[0089] Applying a force to the force application position to elastically deform the elastic deformation area of ​​the guide rail frame, so that the two rotating frames of the guide rail frame move away from each other;

[0090] The guide rail frame is moved to a set position, and the force is withdrawn to cause the elastic deformation area to rebound, so that the two rotating frames clamp the slide block.

[0091] By determining the force application position, the possibility that the force applied to other positions of the guide rail frame cannot drive the elastic deformation area to deform elastically is reduced, and the size of the force required to elastically deform the elastic deformation area is reduced. Through the elastic deformation of the elastic deformation area, the relative position of part of the structure of the guide rail frame is changed, thereby driving the two rotating frames to deform or move, and the two rotating frames are stretched open so that the relative distance between the two rotating frames increases, thereby allowing the slider to enter between the two rotating frames. Move the guide rail frame to a set position so that the slider is between the two rotating frames. After the force is withdrawn, the elastic deformation area lacking the external force will rebound, thereby reducing the relative distance between the two rotating frames until it abuts against the opposite sides of the slider, and the guide rail frame is relatively fixed to the slider under the action of its own elastic force to achieve assembly. Through the above-mentioned assembly method, the guide rail frame's own elastic deformation ability is utilized to automatically clamp the guide rail frame to the slider to complete the assembly, which also saves the process of assembling multiple components of the guide rail frame with each other, thereby simplifying the assembly steps and improving the assembly efficiency.

[0092] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0093] See also Figure 1 and Figure 2 One embodiment of the present application provides a rolling linear guide pair 200. The rolling linear guide pair 200 includes a slide rail 201, a slider 202, a ball 203 and a guide frame 100. The slider 202 is provided with an assembly groove 2021. A portion of the slide rail 201 is located in the assembly groove 2021. The guide frame 100 is connected to the slide rail 201, and a portion of the guide frame 100 is located in the assembly groove 2021 of the slider 202 and between the slider 202 and the slide rail 201. The slider 202 is movably mounted on the slide rail 201 along the length direction of the slide rail 201. When the slider 202 moves relative to the slide rail 201, the ball 203 circulates and rolls between the slider 202 and the guide frame 100.

[0094] The length direction of the slide rail 201 and the length direction of the slider 202 are defined as the first direction X, the height direction of the slider 202 is defined as the second direction Y, and the width direction of the slider 202 is defined as the third direction Z. The first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0095] See also Figure 2In some embodiments, the slider 202 includes a first wall 2021a, a second wall 2021b, and a third wall 2021c connected in sequence. The first wall 2021a, the second wall 2021b, and the third wall 2021c are arranged to form a mounting groove 2021. The second wall 2021b is a groove wall at the bottom of the mounting groove 2021. The second wall 2021b is located on one side of the slide rail 201 in the second direction Y, the first wall 2021a is located on one side of the slide rail 201 in the third direction Z, and the third wall 2021c is located on the side of the slide rail 201 in the third direction Z away from the first wall 2021a.

[0096] See also Figure 2 In some embodiments, the slider 202 is provided with a plurality of circulation channels 2022 extending along the first direction X. In particular, along the third direction Z, the first wall 2021a is provided with a circulation channel 2022 on the side away from the third wall 2021c, and the third wall 2021c is provided with a circulation channel 2022 on the side away from the first wall 2021a. The slider 202 is assembled with the guide rail frame 100 to form a plurality of limiting channels (not shown) extending along the first direction X. In particular, both the first wall 2021a and the third wall 2021c are provided with limiting channels. The ball 203 rolls in contact with the slide rail 201 in the limiting channel. The guide rail frame 100 can guide the ball 203 to turn, so that the ball 203 can roll cyclically between the limiting channel and the circulation channel 2022 on one side of the slide rail 201 along the third direction Z, and roll cyclically between the limiting channel and the circulation channel 2022 on the other side of the slide rail 201 along the third direction Z. Among them, a circulation channel 2022 is correspondingly set for each limiting channel.

[0097] The ball bearing 203 rolls against the slide rail 201 in the limiting channel, which is helpful to reduce the friction when the slider 202 slides along the slide rail 201, and can also assist in correcting the posture of the slider 202 relative to the slide rail 201, thereby helping to improve the sliding speed and accuracy of the slider 202 and improve the sliding stability of the slider 202. In addition, the ball bearing 203 can be guided by the guide rail frame 100 to circulate and roll between the slider 202 and the guide rail frame 100, so as to further reduce the friction between the slider 202 and the slide rail 201.

[0098] See also Figure 2 and Figure 3 In some embodiments, the guide rail frame 100 is an integrally formed structure. The guide rail frame 100 is composed of a first limiting frame 1, a second limiting frame 2 and two rotating frames 3. The first limiting frame 1 is connected to a rotating frame 3 at both ends along the first direction X. The second limiting frame 2 is arranged with the first limiting frame 1 along the second direction Y. The second limiting frame 2 includes two limiting bars 21. Each limiting bar 21 is connected to a rotating frame 3 at both ends along the first direction X. The two limiting bars 21 are arranged opposite to each other along the third direction Z.

[0099] The first limit frame 1, the second limit frame 2 and the two rotating frames 3 are integrally arranged, and the first limit frame 1 and the second limit frame 2 constrain the positions of the two rotating frames 3 in the first direction X, and the two rotating frames 3 constrain the positions of the first limit frame 1 and the second limit frame 2 in the second direction Y, and the two rotating frames 3 constrain the positions of the two limit bars 21 of the second limit frame 2 in the third direction Z, thereby eliminating the process of separately assembling the first limit frame 1, the second limit frame 2 and the two rotating frames 3 with the slider 202 of the rolling linear guide pair 200, and also eliminating the process of assembling the four together, thereby improving the assembly speed, and at the same time there is no error generated when the four are assembled together, therefore, the cumulative error caused by the assembly action can be reduced, and the assembly accuracy can be improved.

[0100] In some embodiments, the first limiting frame 1, the second limiting frame 2 and the two rotating frames 3 are made into an integrally molded guide rail frame 100 through an injection molding process. As an illustrative example, the injection molding process includes but is not limited to 3D printing, injection molding, insert molding, foam molding, nano injection molding, blow molding, extrusion molding, etc. In some embodiments, the materials used in the injection molding process of the guide rail frame 100 include but are not limited to engineering plastics such as polyoxymethylene (POM), polyamide (PA66, PA6, PA46), and polyetheretherketone (PEEK), and various reinforcing materials such as glass fiber, carbon fiber, and graphene can be further added to the above materials to enhance the overall structural strength and wear resistance of the guide rail frame 100.

[0101] See also Figure 2 and Figure 3 In some embodiments, the two rotating frames 3 are respectively pressed on the two ends of the slider 202 along the first direction X. At least one of the first limiting frame 1 and the second limiting frame 2 is assembled with the slider 202 to form a limiting channel. The ball 203 circulates and rolls between the limiting channel and the circulation channel 2022 through the two rotating frames 3.

[0102] See also Figure 2 and Figure 3 In some embodiments, the connection structure between the rotating frame 3 and the first limiting frame 1 and the second limiting frame 2 is an elastic connection structure. The two rotating frames 3 are configured to elastically press the slider 202, and the two limiting bars 21 are configured to elastically press the slider 202. Thus, the guide rail frame 100 can elastically press the slider 202, improve the tightness of the assembly of the guide rail frame 100 and the slider 202, thereby reducing the error caused by the assembly, and improving the sliding speed and stability of the slider 202.

[0103] See also Figure 2In some embodiments, the rolling linear guide pair 200 further includes two end covers 204. In the first direction X, the two end covers 204 are respectively connected to opposite ends of the slider 202. Each end cover 204 is respectively provided with a rotating frame 3. When the ball 203 is turned through the rotating frame 3, the end cover 204 constrains the rolling of the ball 203 to prevent the ball 203 from escaping from the rotating frame 3.

[0104] See also Figure 2 and Figure 3 In some embodiments, each rotating frame 3 is provided with a plurality of arc-shaped protrusions 31. A rotating channel 32 is formed between two adjacent arc-shaped protrusions 31. The plurality of arc-shaped protrusions 31 of the same rotating frame 3 are located on the same side in the first direction X, and are all located on the side away from the slider 202 along the first direction X. The rotating channel 32 formed by providing the arc-shaped protrusions 31 enables the balls 203 of the rolling linear guide pair 200 to circulate and roll between the slider 202 and the guide frame 100. Each end cover 204 is provided with an arc-shaped recess 2041. The arc-shaped recess 2041 of each end cover 204 cooperates with a rotating frame 3 to guide the balls 203 to circulate and roll between the limiting channel and the circulation channel 2022. The arc-shaped recess 2041 is recessed along the first direction X in a direction away from the corresponding rotating frame 3. Each rotary frame 3 is provided with a plurality of rotary channels 32 , and each end cover 204 is provided with a plurality of arc-shaped recesses 2041 , and each arc-shaped recess 2041 is provided correspondingly to a rotary channel 32 .

[0105] See also Figure 2 and Figure 3 It can be understood that in some embodiments, the slider 202 is provided with at least one pair of limiting channels and circulation channels 2022 on opposite sides in the third direction Z. Both ends of each pair of limiting channels and circulation channels 2022 along the first direction X are correspondingly configured with a rotation channel 32 and an arc-shaped recess 2041. Therefore, each rotating frame 3 is provided with a rotation channel 32 on both sides of the slide rail 201 along the third direction Z, and each end cover 204 is provided with an arc-shaped recess 2041 on both sides of the slide rail 201 along the third direction Z. In some embodiments, the slide rail 201 is provided with multiple pairs of limiting channels and circulation channels 2022 arranged along the second direction Y on one side along the third direction Z, and multiple pairs of limiting channels and circulation channels 2022 arranged along the second direction Y are also provided on the other side. Each rotating frame 3 is provided with multiple rotation channels 32 arranged along the second direction Y on one side of the slide rail 201 along the third direction Z, and multiple rotation channels 32 arranged along the second direction Y on the other side of the slide rail 201 along the third direction Z. Each end cover 204 is provided with a plurality of arc-shaped recesses 2041 arranged along the second direction Y on one side of the slide rail 201 along the third direction Z, and a plurality of arc-shaped recesses 2041 arranged along the second direction Y on the other side of the slide rail 201 along the third direction Z.

[0106] See also Figure 2 In some embodiments, the rolling linear guide pair 200 further includes a first bracket 205 and a second bracket 206. The first bracket 205 and the second bracket 206 are arranged in the assembly groove 2021 of the slider 202. The first bracket 205 and the second bracket 206 both extend along the first direction X. In the third direction Z, the first bracket 205 and the second bracket 206 are respectively arranged on both sides of the slide rail 201. In the third direction Z, the first bracket 205 is located between the first limiting frame 1 and the second limiting frame 2, and the second bracket 206 is located between the first limiting frame 1 and the second limiting frame 2. The first bracket 205 cooperates with the first limiting frame 1 and a limiting strip 21 at the same time, and cooperates with the slider 202 to form two limiting channels located on one side of the slide rail 201, wherein the first bracket 205, the first limiting frame 1, and the slider 202 cooperate to form a limiting channel located on one side of the slide rail 201, and the first bracket 205, the limiting strip 21, and the slider 202 cooperate to form another limiting channel located on one side of the slide rail 201. The second bracket 206 cooperates with the first limit frame 1 and the other limit strip 21 at the same time, and cooperates with the slider 202 to form two limit channels located on the other side of the slide rail 201, wherein the second bracket 206, the first limit frame 1, and the slider 202 cooperate to form a limit channel located on the other side of the slide rail 201, and the second bracket 206, the limit strip 21, and the slider 202 cooperate to form another limit channel located on the other side of the slide rail 201.

[0107] It is understandable that in other embodiments, the first bracket 205 and the second bracket 206 can be omitted, the slider 202 cooperates with one side of the first limit frame 1 and a limit strip 21 to form one or more limit channels, and the slider 202 cooperates with the other side of the first limit frame 1 and another limit strip 21 to form one or more limit channels; or, multiple first brackets 205 and second brackets 206 can be set, two adjacent first brackets 205 cooperate with the slider 202 to form a limit channel, and two adjacent second brackets 206 cooperate to form a limit channel.

[0108] See also Figure 1 , Figure 2 and Figure 4 In some embodiments, the guide rail frame 100 is assembled to the slider 202 by an assembly method of the guide rail frame. The assembly method of the guide rail frame includes:

[0109] Select a force application position on the guide rail frame 100;

[0110] Applying a force to the force application position causes the elastic deformation area of ​​the guide rail frame 100 to elastically deform, so that the two rotating frames 3 of the guide rail frame 100 are separated from each other;

[0111] The guide rail frame 100 is moved to a set position, and the force is removed to cause the elastic deformation area to rebound, so that the two rotating frames 3 clamp the slider 202 .

[0112] The specific steps of the above method may be:

[0113] Step S1: selecting a force application position on the guide rail frame 100 .

[0114] Step S2: applying a force to the force application position to elastically deform the elastic deformation area of ​​the guide rail frame 100, so that the two rotating frames 3 of the guide rail frame 100 are separated from each other.

[0115] Step S3: Move the guide rail frame 100 to a set position, remove the force to make the elastic deformation area rebound, so that the two rotating frames 3 clamp the slider 202.

[0116] By determining the force application position, the possibility that the force applied to other positions of the guide rail frame 100 cannot drive the elastic deformation area to deform elastically is reduced, and the magnitude of the force required to elastically deform the elastic deformation area is reduced. Through the elastic deformation of the elastic deformation area, the relative position of part of the structure of the guide rail frame 100 is changed, thereby driving the two rotating frames 3 to deform or move, and the two rotating frames 3 are stretched apart so that the relative distance between the two rotating frames 3 increases, thereby allowing the slider 202 to enter between the two rotating frames 3. The guide rail frame 100 is moved to the set position so that the slider 202 is between the two rotating frames 3. After the force is withdrawn, the elastic deformation area without external force will rebound, thereby reducing the relative distance between the two rotating frames 3 until it abuts against the opposite sides of the slider 202. Under the action of its own elastic force, the guide rail frame 100 is relatively fixed to the slider 202 to achieve assembly. Through the above assembly method, the elastic deformation ability of the guide rail frame 100 is utilized to automatically clamp the guide rail frame 100 to the slider 202 to complete the assembly, thus eliminating the process of assembling multiple components of the guide rail frame 100, thereby simplifying the assembly steps and improving the assembly efficiency.

[0117] In some embodiments, the guide rail frame assembly method further includes:

[0118] After the two rotating frames 3 move away from each other along the first direction X, the first limiting frame 1 and the second limiting frame 2 are respectively abutted against different positions of the slider 202, so that the guide rail frame 100 and the slider 202 are positioned relative to each other. Then, the force is withdrawn, so that the elastic deformation area rebounds, driving the two rotating frames 3 to clamp the two ends of the slider 202 along the first direction X, thereby realizing the assembly of the guide rail frame 100 to the slider 202.

[0119] In some embodiments, the assembly method of the guide rail frame further includes: providing an assembly mechanism (not shown). The assembly mechanism applies a force to the force application position to elastically deform the elastic deformation area. In other embodiments, the assembly mechanism can be omitted, and the assembly method of the guide rail frame further includes: manually applying a force to the force application position to elastically deform the elastic deformation area.

[0120] In some embodiments, the assembly mechanism includes a mechanical arm. The step of applying a force to the force application position to elastically deform the elastic deformation region includes:

[0121] The robot arm applies a force to the force application position to elastically deform the elastic deformation area.

[0122] The step of moving the guide rail frame 100 to a set position includes:

[0123] The robot arm moves the guide rail frame 100 to a set position.

[0124] By applying the force to the force application position through the mechanical arm, the accuracy of the position and size of the force application is improved, which is conducive to improving the assembly efficiency. After the mechanical arm 100 opens the two rotating frames 3, the rebound tendency of the elastic deformation area enables the guide rail frame 100 to be relatively fixed to the mechanical arm, so that it is convenient for the mechanical arm to drive the guide rail frame 100 to move. By moving the guide rail frame 100 by the mechanical arm, it is convenient to improve the accuracy of the guide rail frame 100 moving to the set position, which is conducive to accurately moving the two rotating frames 3 to the two sides of the slider 202. In addition, the structure of opening the two rotating frames 3 and the structure of positioning the guide rail frame 100 and the slider 202 are integrated into the mechanical arm, and the assembly of the guide rail frame 100 can be realized by controlling the mechanical arm, simplifying the assembly steps, which is conducive to improving the assembly efficiency.

[0125] In some embodiments, the first limit frame 1 includes a limit frame body 11 and an elastic structure 12. Two elastic structures 12 are provided. The two ends of the limit frame body 11 along the first direction X are connected to a rotating frame 3 through an elastic structure 12 respectively. Each rotating frame 3 is connected to an elastic structure 12 to form an elastic deformation area. The elastic deformation of each elastic structure 12 drives the connected rotating frame 3 to elastically deform or move relatively, so that one end of each rotating frame 3 connected to the first limit frame 1 along the second direction Y moves away from the first limit frame 1 along the first direction X. Thereby, the slider 202 enters between the two rotating frames 3 along the direction from the first limit frame 1 to the second limit frame 2, so that the first limit frame 1 enters the assembly groove 2021 and abuts against the second wall 2021b.

[0126] In some embodiments, the selecting of the force application position on the guide rail frame 100 includes: selecting at least one force application position on both sides of the two rotating frames 3 of the guide rail frame 100. The applying of the force to the force application position to elastically deform the elastic deformation area of ​​the guide rail frame 100 includes: making the directions of the forces applied to the force application positions on both sides of the two rotating members opposite to each other. That is, the direction of the applied force is away from the first limit frame 1 along the first direction X.

[0127] In some embodiments, the step of selecting a force application position in the elastic deformation region of the guide rail frame 100 includes:

[0128] The force application positions are located at the two elastic structures 12 .

[0129] The step of applying a force to the force application position to elastically deform the elastic deformation area of ​​the guide rail frame 100 includes:

[0130] Applying force to the two elastic structures 12 causes the two elastic structures 12 to elastically deform.

[0131] The force acts directly on the elastic structure 12, causing the elastic structure 12 to stably produce elastic deformation, thereby driving the rotating frame 3 connected to the elastic structure 12 to deform or move, improving the stability of the spreading action of moving the two rotating frames 3 away from each other, which is beneficial to improving the success rate of assembly, thereby reducing the time wasted due to assembly failure and helping to improve assembly efficiency.

[0132] See also Figure 3 In some embodiments, each elastic structure 12 is provided with a connecting hole 121. The step of applying a force to the two elastic structures 12 to elastically deform the two elastic structures 12 includes:

[0133] The assembly mechanism extends into the connection hole 121 of each elastic structure 12 and applies a force to each elastic structure 12 , and the directions of the forces applied to the two elastic structures 12 are opposite to each other.

[0134] The assembly mechanism extends into the connection hole 121 and applies a force to the elastic structure 12, thereby improving the stability of the connection between the assembly structure and the elastic structure 12, thereby enhancing the stability of the force applied to the elastic structure 12. The assembly mechanism applies a force to elastically deform the two elastic structures 12 in a direction away from each other, thereby driving the respective connected rotating frames 3 away from each other, and the direction of the force application is consistent with the direction of deformation or movement of the rotating frame 3, and the assembly action is continuous, which is convenient for improving the assembly efficiency.

[0135] See also Figure 3 In some embodiments, the elastic structure 12 is a folded strip structure so that the limit frame body 11 is elastically connected to the rotating frame 3. In some embodiments, the elastic structure 12 is formed by a plurality of folded strip structures connected to each other along the first direction X and the third direction Z. A connecting hole 121 is formed between the plurality of folded strip structures. It is understood that in some embodiments, the hole shape of the connecting hole 121 is square, and in other embodiments, the hole shape of the connecting hole 121 includes but is not limited to a triangle, a diamond, and the like.

[0136] See also Figure 1 In some embodiments, the step of selecting a force application position in the elastic deformation region of the guide rail frame 100 includes:

[0137] The force application positions are located at the two rotating frames 3 .

[0138] The step of applying a force to the force application position to elastically deform the elastic deformation area of ​​the guide rail frame 100 includes:

[0139] A force is applied to the two rotating frames 3 to elastically deform the two elastic structures 12 .

[0140] The force applied to the rotating frame 3 is transmitted to the elastic structure 12 connected to the rotating frame 3 to cause the elastic structure 12 to deform elastically, thereby moving the two rotating frames 3 away from each other. The force is directly applied to the rotating frame 3, so that after the force changes, the position of the rotating frame 3 can be changed in time, thereby improving the accuracy of the position of the two rotating frames 3 away from each other. On the one hand, the possibility of damage to the guide frame 100 caused by excessive deformation or displacement of the rotating frame 3 is reduced, and on the other hand, it is easier to ensure that the distance between the two rotating frames 3 can be set to the slider 202. This is conducive to improving the success rate of assembly, thereby reducing the time wasted due to assembly failure, and is conducive to improving assembly efficiency.

[0141] In some embodiments, the force application position is located at a side of each rotating frame 3 that is away from the arc-shaped protrusion 31 .

[0142] In some embodiments, the force application position is located only on the two elastic structures 12 , or only on the two rotating frames 3 , or simultaneously on the elastic structure 12 and the rotating frames 3 .

[0143] In some embodiments, the assembly mechanism further comprises a pressure sensing component, and the pressure sensing component is disposed on the robot arm.

[0144] The mechanical arm applies a force to the force application position, including:

[0145] The robot arm applies a gradually increasing force to the force application position until the pressure sensing component detects that the force is equal to the set pressure, and the robot arm maintains the set pressure to elastically deform the elastic deformation area.

[0146] The pressure sensing element can reduce the possibility of excessive force applied by the robot arm to the force application position, reduce the possibility of direct damage to the guide rail frame 100 or failure of the elastic deformation area to rebound smoothly, thereby improving assembly efficiency.

[0147] It is understandable that, in some embodiments, the size of the set pressure is related to the specific material and size of the guide rail frame 100 .

[0148] In some embodiments, the assembly mechanism further includes a displacement sensing component.

[0149] The mechanical arm applies a force to the force application position, including:

[0150] The mechanical arm applies a gradually increasing force to the force application position until the displacement sensing component detects that the distance between the two rotating frames 3 is equal to the set distance, and the mechanical arm maintains the force to elastically deform the elastic deformation area.

[0151] The displacement sensing element can reduce the possibility of excessive deformation or displacement of the rotating frame 3, reduce the possibility of direct damage to the guide rail frame 100 or failure of the elastic deformation area to rebound smoothly, and thus improve assembly efficiency.

[0152] In some embodiments, the displacement sensing element detects the moving distance of one end of each rotating frame 3 connected to the first limiting frame 1 along the second direction Y relative to the first limiting frame 1 in the first direction X. It can be understood that in some embodiments, the set distance satisfies that, when observed along the third direction Z, with one end of the rotating frame 3 connected to the second limiting frame 2 along the second direction Y as the axis, the angle at which the end of the rotating frame 3 connected to the first limiting frame 1 along the second direction Y rotates is less than 15°.

[0153] In some embodiments, the mechanical arm applies a force to the force application position to elastically deform the elastic deformation area, including:

[0154] The robot arm applies a gradually increasing force to the force application position, and at the same time, the pressure sensing component detects that the force is equal to the set pressure and the displacement monitoring room detects that the distance between the two rotating frames 3 is equal to the set distance.

[0155] In other embodiments, when the robot arm applies a gradually increasing force to the force application position, one of the following is satisfied: the force detected by the pressure sensing element is equal to the set pressure and the distance between the two rotating frames 3 detected by the displacement monitoring is equal to the set distance.

[0156] In some embodiments, the assembly mechanism further includes a pressing member.

[0157] The step of moving the guide rail frame 100 to a set position includes:

[0158] The pressing member presses the guide rail frame 100 toward the slider 202 .

[0159] The guide rail frame 100 is pressed by the pressing member so that the guide rail frame 100 and the slider 202 are relatively fixed, which is beneficial to improving the accuracy of the position of the two rotating frames 3 clamping the slider 202, improving the success rate of assembling the guide rail frame 100 to the slider 202, and improving the assembly efficiency.

[0160] It is understood that in some embodiments, the pressing member is provided on the robot arm, and the movement of the robot arm can drive the pressing member to move. In order to facilitate the pressing member to move with the robot arm, the step of positioning the pressing member and the guide rail frame 100 connected to the robot arm is omitted, thereby improving the assembly efficiency. The pressing member moves relative to the robot arm, so as to facilitate pressing the guide rail frame 100 to be fixed relative to the slider 202.

[0161] In some embodiments, the assembly mechanism further comprises a fixing member. The fixing member is arranged at a set position. The assembly method of the guide rail frame further comprises:

[0162] Before the robot arm moves the guide rail frame 100 to a set position, the slider 202 is fixed to a fixing member.

[0163] The fixing member fixes the slider 202 so that the robot arm can determine the position of the slider 202 , thereby improving the accuracy of the robot arm in assembling the guide rail frame 100 to the slider 202 .

[0164] In other embodiments, the fixing member may be omitted. After the guide rail frame 100 is connected to the robot arm, and the robot arm applies a force to the force application position to elastically deform the elastic deformation area, the robot arm does not move the guide rail frame 100, but moves the slider 202 to the position of the robot arm, thereby removing the force so that the two rotating frames 3 clamp the slider 202.

[0165] In some embodiments, the evacuation force causes the elastic deformation area to rebound, including:

[0166] The force applied by the robot arm is released to allow the elastically deformed area to rebound.

[0167] The force applied by the robot arm causes the robot arm to actively stop driving the elastic deformation area to deform elastically. By controlling the robot arm, the opening action of the two rotating frames 3 and the assembly action of the rotating frame 3 clamping the slider 202 can be realized, which simplifies the control logic of the assembly mechanism and is conducive to improving the assembly efficiency.

[0168] In other embodiments, the evacuation force causes the elastic deformation area to rebound, including: separating the guide rail frame 100 from the robot arm, causing the elastic deformation area to rebound. The robot arm passively stops driving the elastic deformation area to elastically deform, saving the time for the robot arm to move, thereby improving the efficiency of the elastic deformation area rebounding, which is beneficial to improving the assembly efficiency. In other embodiments, separating the guide rail frame 100 from the robot arm and releasing the force applied by the robot arm can be performed at the same time; or separating the guide rail frame 100 from the robot arm and releasing the force applied by the robot arm can be performed one by one.

[0169] In addition, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application and are not intended to be limiting of the present application. As long as they are within the spirit and scope of the present application, appropriate changes and modifications to the above embodiments are within the scope of the present application.
