Description

Technical Field

[0001] This utility model relates to the technical field of concealed rail assembly equipment, and in particular to a ball bearing mounting device for a three-section synchronous concealed rail. Background Technology

[0002] Three-section synchronous concealed rails are a type of drawer slide designed to enhance the aesthetics of furniture. Their core feature is that the main body of the rail is hidden inside the furniture and is almost invisible from the outside, thus achieving a trackless visual effect for drawers and cabinets. The three-section synchronous concealed rail includes an outer rail, a middle rail, and an inner rail that are set together in sequence. The inner rail and the middle rail will be equipped with an upper ball bearing bracket, and the middle rail and the outer rail will be equipped with a lower ball bearing bracket. The upper and lower ball bearing brackets are equipped with balls to support the sliding of the guide rail. The upper ball bearing bracket is made of plastic. In order to ensure the smooth sliding of the upper ball bearing bracket between the inner rail and the middle rail and to prevent slippage, the upper ball bearing bracket is elastically deformed and then snapped onto the middle rail. Currently, with the automation of concealed rail assembly, the previous method of manually assembling the upper bead frame onto the middle rail is gradually being replaced by automated equipment. The existing concealed rail upper bead frame installation device uses a material picker to pick up the upper bead frame and transfer it onto the middle rail. Then, the material picker moves downward toward the middle rail, thereby assembling the upper bead frame onto the middle rail.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: Firstly, because the material-picking clamp uses a vertical up-and-down assembly action, the contact force between the upper ball bearing and the middle rail is too large. This causes the balls on the ball bearing to easily fall off due to excessive local compression, or the ball bearing may be damaged or broken during installation. The assembly effect is inferior to the flexible installation of manual assembly, increasing the risk of rework in the assembly of the hidden rail, thus affecting installation efficiency. Secondly, the clamping position of the material-picking clamp is fixed, and usually a single set of material-picking clamps is used to clamp the upper ball bearing, making it difficult to accommodate the transfer and assembly of upper ball bearings of different sizes. Furthermore, the use of a single set of material-picking clamps easily leads to uneven force on the upper ball bearing during fastening, further increasing the likelihood of balls falling off or the ball bearing being damaged or broken. Utility Model Content

[0004] To address the issue of instability in the installation of the upper bead frame caused by its vertical assembly on the middle rail, this application provides a three-section synchronous concealed rail upper bead frame installation device.

[0005] The present invention provides a three-section synchronous concealed rail bead frame mounting device, which adopts the following technical solution: A three-section synchronous concealed track bead holder installation device includes a fixed bracket, a sliding bracket, a lifting bracket, and a clamping mechanism. The sliding bracket is slidably assembled with the fixed bracket and moves back and forth along the lateral direction of the sliding bracket. The lifting bracket is slidably assembled with the sliding bracket and moves back and forth along the vertical direction of the sliding bracket. The clamping mechanism is assembled with the lifting bracket and is used to clamp the upper bead holder. The clamping mechanism includes a first clamping assembly, which includes a first picking clamp, a first picking cylinder, and a first angle swing cylinder. The first picking cylinder is assembled below the lifting bracket and is used to control the first picking clamp to loosen and release the upper bead holder. The first angle swing cylinder is assembled with the lifting bracket and is used to control the first picking cylinder to swing.

[0006] Preferably, the first clamping assembly further includes a first connector and a U-shaped block. The U-shaped block is connected to the bottom of the lifting bracket. One end of the first connector is rotatably assembled with the U-shaped block. The fixed end of the first picking cylinder is connected to one end of the first connector and is located below the U-shaped block. The movable end of the first angle swing cylinder is rotatably assembled with the other end of the first connector. The fixed end of the first angle swing cylinder is rotatably assembled with the lifting bracket.

[0007] Preferably, the clamping mechanism further includes several sets of second clamping components, wherein the first clamping components and the second clamping components are arranged at lateral intervals along the lifting bracket.

[0008] Preferably, the clamping mechanism further includes an adjusting screw, an adjusting screw nut, and an adjusting screw motor.

[0009] Preferably, the second clamping assembly further includes a second picking clamp, a second picking cylinder, and a second angle swing cylinder. The second picking cylinder is mounted below the lifting bracket and is used to control the second picking clamp to loosen and release the upper bead holder. The second angle swing cylinder is mounted with the lifting bracket and is used to control the swing of the second picking cylinder.

[0010] Preferably, the second clamping assembly further includes a second connector and a C-shaped block. The bottom of the second connector 504 is rotatably assembled with the C-shaped block, and the top of the C-shaped block is connected to the adjusting screw nut. The fixed end of the second picking cylinder is connected to one end of the second connector 504 and is located below the C-shaped block. The movable end of the second angle swing cylinder is rotatably assembled with the other end of the first connector, and the fixed end of the second angle swing cylinder is rotatably assembled with the top of the C-shaped block.

[0011] Preferably, the second material handling clamp includes a clamp base, a clamp block, and a spring. The clamp block is slidably assembled with the clamp base and is used to abut against the upper bead frame. The two ends of the spring are respectively used to connect the clamp base and the clamp block.

[0012] Preferably, the system further includes a lifting cylinder, the fixed end of which is connected to the sliding bracket, and the movable end of which is connected to the lifting bracket. The lifting bracket and the sliding bracket are slidably assembled via a slide rail slider.

[0013] Preferably, the first angle swing cylinder is located on the side of the lifting bracket away from the sliding bracket, and the second angle swing cylinder is located on the side of the lifting bracket closer to the sliding bracket. When the first angle swing cylinder is in the reset state and the second angle swing cylinder is in the extended state, the clamping mechanism holds the upper bead frame parallel to the lifting bracket.

[0015] The beneficial effects of this utility model are as follows: By incorporating a first-angle swing cylinder and a second-angle swing cylinder, the freedom of the material handling clamp is increased. This allows for a combined vertical lifting and angular swinging installation of the upper ball bearing and the middle rail. This effectively addresses slight misalignment or angular mismatch issues that may occur during workpiece installation, enabling a tilted contact followed by a return to centering and locking action. This decomposes concentrated impact force into smooth lateral thrust and slight downward pressure, mitigating assembly stress and simulating the flexible process of manual assembly. This results in more precise positioning and embedding, reduces the installation failure rate, and improves the overall operational stability of the workstation.

[0016] The first material handling component keeps the material in a fixed position, while the second material handling components on both sides are driven by a lead screw and a motor to achieve variable pitch adjustment. This improves the adaptability of the clamping mechanism to upper bead frames of different lengths. By adjusting the rotation of the lead screw, the distance between the second material handling components on both sides can be flexibly adjusted to meet the needs of picking up and placing workpieces of different sizes. This structure not only enhances the versatility of the equipment, but also reduces manual intervention and improves the degree of automation and production efficiency.

[0017] By adding a spring buffer to the second material handling clamp, a certain amount of elastic displacement can be provided when clamping or placing the upper ball frame, realizing soft contact clamping and installation. While ensuring installation accuracy, the reliability of the system is significantly improved, and the risk of ball detachment due to uneven force on the upper ball frame during assembly with the middle rail is effectively avoided.

[0025] Example: Figure 1-10 As shown, a three-section synchronous concealed rail bead frame installation device includes a fixed bracket 1, a sliding bracket 2, a lifting bracket 3, and a clamping mechanism. The sliding bracket 2 is slidably assembled with the fixed bracket 1 and moves back and forth along the lateral direction of the sliding bracket 2. The lifting bracket 3 is slidably assembled with the sliding bracket 2 and moves back and forth along the vertical direction of the sliding bracket 2. The clamping mechanism is assembled with the lifting bracket 3 and is used to clamp the upper bead frame. The clamping mechanism includes a first clamping assembly, which includes a first picking clamp 401, a first picking cylinder 402, and a first angle swing cylinder 403. The first picking cylinder 402 is assembled below the lifting bracket 3 and is used to control the first picking clamp 401 to loosen and release the upper bead frame. The first angle swing cylinder 403 is assembled with the lifting bracket 3 and is used to control the swing of the first picking cylinder 402. Specifically, the first... Two sets of material-picking clamps 401 are provided. The two sets of first material-picking clamps 401 are respectively connected to the movable end of the first material-picking cylinder 402. The fixed end of the first material-picking cylinder 402 is rotatably mounted on the bottom wall of the lifting bracket 3. The fixed end of the first angle swing cylinder 403 is mounted on the lifting bracket 3, and the movable end of the first angle swing cylinder 403 is mounted on the fixed end of the first material-picking cylinder 402. This allows the upper bead frame to move vertically up and down and swing when it is engaged with the middle rail. The first material-picking cylinder 402 is controlled to swing, causing the upper bead frame to tilt. Then, the lifting bracket 3 moves down, causing the tilted upper bead frame to contact the middle rail. Then, the first angle swing cylinder 403 resets, controlling the first material-picking cylinder 402 to return to the center, thus allowing the upper bead frame to be mounted on the middle rail. By first tilting the contact point and then straightening it for engagement, the concentrated impact force is decomposed into a smooth lateral thrust and a slight downward pressure, which eases the assembly effort, simulates the flexible process of manual assembly, reduces the defect rate and rework costs, and improves the stability and consistency of the assembly process.

[0026] Regarding the specific structure of the first angle swing cylinder 403 controlling the swing of the first material picking cylinder 402, the first clamping assembly also includes a first connecting member 404 and a U-shaped block 405. The U-shaped block 405 is connected to the bottom of the lifting bracket 3. One end of the first connecting member 404 is rotatably assembled with the U-shaped block 405. The fixed end of the first material picking cylinder 402 is connected to one end of the first connecting member 404 and is located below the U-shaped block 405. The movable end of the first angle swing cylinder 403 is rotatably assembled with the other end of the first connecting member 404. The fixed end of the first angle swing cylinder 403 is rotatably assembled with the lifting bracket 3. It is worth mentioning that the rotation center of one end of the first connecting member 404 and the U-shaped block 405 is located on the axis of symmetry of the two sets of first material picking clamps 401. The swing and return of the first material picking cylinder 402 are controlled by the extension and retraction movement of the movable end of the first angle cylinder.

[0027] To improve the stability of the clamping mechanism in holding the upper ball frame, the clamping mechanism also includes several sets of second clamping components. The first clamping components and the second clamping components are arranged at a lateral interval along the lifting bracket 3.

[0028] In this embodiment, two sets of second clamping components are provided, with the two sets of second clamping components located on both sides of the first clamping component. By providing the second clamping components, the clamping force is distributed and balanced, ensuring that the upper bead frame maintains the preset and precise posture during the assembly process, thereby improving the clamping stability of the upper bead frame.

[0029] To achieve compatibility of the clamping mechanism with bead holders of different lengths, the clamping mechanism also includes an adjusting screw 601, an adjusting screw nut 602, and an adjusting screw motor 603. The adjusting screw 601 is rotatably assembled with the lifting bracket 3, the adjusting screw nut 602 is threadedly connected to the adjusting screw 601, and the adjusting screw motor 603 is assembled with the lifting bracket 3 and used to rotate the adjusting screw 601. Specifically, the fixed end of the adjusting screw motor 603 is connected to the lifting bracket 3, and the movable end of the adjusting screw motor 603 is axially connected to the adjusting screw 601. The second clamping assembly is assembled with the adjusting screw nut 602, and the second clamping assembly moves back and forth toward the first clamping assembly. By driving the screw to rotate through the adjusting screw motor 603, the nut threadedly connected to it moves linearly, thereby precisely controlling the position of the second clamping assembly, improving the compatibility of the clamping mechanism with upper bead holders of different lengths, and shortening the model changeover time and the non-productive time of the production line.

[0030] Regarding the specific structural design of the second clamping assembly, the second clamping assembly also includes a second material-picking clamp 501, a second material-picking cylinder 502, and a second angle swing cylinder 503. The second material-picking cylinder 502 is mounted below the lifting bracket 3 and is used to control the second material-picking clamp 501 to loosen and release the upper bead holder. The second angle swing cylinder 503 is mounted with the lifting bracket 3 and is used to control the swing of the second material-picking cylinder 502. Specifically, two sets of second material-picking clamps 501 are provided, and the two sets of second material-picking clamps 501 are respectively connected to the movable end of the second material-picking cylinder 502. The fixed end of 02 is rotatably mounted on the bottom wall of the lifting bracket 3. The fixed end of the second angle swing cylinder 503 is mounted with the lifting bracket 3, and the movable end of the second angle swing cylinder 503 is mounted with the fixed end of the second picking cylinder 502. Since the upper ball frame is long and narrow, it is clamped at intervals by setting the first clamping component and the second clamping component, forming a multi-point coordinated clamping, which effectively suppresses the deformation and vibration of the upper ball frame and improves the stability of the assembly between the upper ball frame and the middle rail. At the same time, the second clamping component and the first clamping component synchronously make the upper ball frame swing, so that the upper ball frame is assembled with the middle rail.

[0031] Regarding the assembly structure of the second material-picking cylinder 502 and the adjusting screw nut 602, the second clamping assembly also includes a second connecting member 504 and a C-shaped block 505. The bottom of the second connecting member 504 is rotatably assembled with the C-shaped block 505, and the top of the C-shaped block 505 is connected to the adjusting screw nut 602. The fixed end of the second material-picking cylinder 502 is connected to one end of the second connecting member 504 and is located below the C-shaped block 505. The movable end of the second angle swing cylinder 503 is rotatably assembled with the other end of the first connecting member 404, and the fixed end of the second angle swing cylinder 503 is rotatably assembled with the top of the C-shaped block 505. By providing the C-shaped block 505, the second material-picking cylinder 502 can slide laterally along the lifting bracket 3 while swinging, improving the compactness of the material-picking mechanism structure design, reducing the volume occupied, and facilitating the optimization of equipment space layout.

[0032] To ensure smooth sliding of the C-block 505, the C-block 505 is connected to the side wall of the lifting bracket 3 via a slide rail slider. Specifically, the second clamping assembly also includes an adjustable slide rail and an adjustable slider. The adjustable slide rail is connected to the side wall of the lifting bracket 3, one side of the adjustable slider is slidably connected to the adjustable slide rail, and the other side of the adjustable slide rail is connected to the C-block 505. It is worth mentioning that one end of the second connector 504 and the rotation center of the C-block 505 are located on the axis of symmetry of the two sets of second material handling clamps 501.

[0033] Since the ball bearings of the upper ball bearing are located at both ends of the upper ball bearing, corresponding to the positions of the two sets of second material-picking clamps 501, to prevent the risk of the ball bearings falling off during assembly of the upper ball bearing and the middle rail, the second material-picking clamp 501 includes a clamp seat 5011, a clamp block 5012, and a spring in its specific structural design. The clamp block 5012 is slidably assembled with the clamp seat 5011, and the clamp block 5012 is used to abut against the upper ball bearing. The two ends of the spring are respectively used to connect the clamp seat 5011 and the clamp block 5011. 012, the second material-picking clamp 501 is a flexible clamp, providing elastic space for the ball bearings. The clamping force of the clamping block 5012 is provided by the preload of the spring and the second material-picking cylinder 502. When the clamping block 5012 contacts the upper ball bearing frame, the spring will be compressed by a small distance according to the actual contour and size of the upper ball bearing frame until a balanced clamping force is reached to ensure stable clamping of the ball bearing frame body, prevent deformation and compression of the ball bearing fixing structure, reduce the risk of ball falling, and improve the installation stability of the upper ball bearing frame.

[0034] Furthermore, in order to improve the stability of the sliding of the clamping block 5012, the clamping seat 5011 is provided with a sliding cavity adapted to the shape of the clamping block 5012. One end of the spring is connected to the inner wall of the sliding cavity, and the other end of the spring is connected to the slider, so that the clamping block 5012 moves back and forth along the inner wall of the sliding cavity provided by the clamping seat 5011.

[0035] Regarding the lifting structure of the lifting bracket 3 and the sliding bracket 2, this embodiment also includes a lifting cylinder 301, a lifting slide rail 301, and a lifting slider 303. The fixed end of the lifting cylinder 301 is connected to the sliding bracket 2, and the movable end of the lifting cylinder 301 is connected to the lifting bracket 3. The lifting bracket 3 and the sliding bracket 2 are slidably assembled via the slide rail and slider. Specifically, the lifting slide rail 301 is connected to the sliding bracket 2, one side of the lifting slider 303 is slidably assembled with the lifting slide rail 301, and the other side of the lifting slider 303 is connected to the lifting bracket 3. The first clamping assembly is located below the lifting cylinder 301. By electrically connecting the lifting cylinder 301 to the processor, the lifting cylinder 301 is controlled to lift and lower, thereby enabling the clamping mechanism to complete the action of picking up the upper bead frame and assembling the upper bead frame with the middle rail.

[0036] Because an upgraded cylinder is provided to lift and slide the lifting bracket 3, and the second clamping assembly can slide along the lifting bracket 3, the positions of the first angle swing cylinder 403 and the second angle swing cylinder 503 need to be rationally arranged to avoid interference during movement. To solve the above technical problem, the first angle swing cylinder 403 is located on the side of the lifting bracket 3 away from the sliding bracket 2, and the second angle swing cylinder 503 is located on the side of the lifting bracket 3 closer to the sliding bracket 2. When the first angle swing cylinder 403 is in the reset state and the second angle swing cylinder 503 is in the extended state, the clamping mechanism clamps... The upper ball frame is parallel to the lifting bracket 3, meaning the upper ball frame is in the centered state. Since the first angle swing cylinder 403 and the second angle swing cylinder 503 are located on the longitudinal sides of the lifting bracket 3 respectively, the reset and extension states of the first angle swing cylinder 403 and the second angle swing cylinder 503 need to be different to ensure synchronous control of the upper ball frame's posture. When it is necessary to tilt the upper ball frame, the controller connected by electricity controls the first angle swing cylinder 403 to be in the extension state and the second angle swing cylinder 503 to be in the reset state, thereby realizing the tilting of the upper ball frame held by the clamping mechanism, which facilitates the assembly of the upper ball frame with the middle rail.

[0037] To adjust the swing angle of the first material-picking cylinder 402, the clamping mechanism also includes a limiting screw 701. The bottom wall of the lifting bracket 3 has a threaded hole for screwing the limiting screw 701. The side wall of the first connecting member 404 has a limiting groove, and the limiting screw 701 is located in the limiting groove. By adjusting the screwing length between the limiting screw 701 and the lifting bracket 3, it abuts against the first connecting member 404 when it swings, thereby adjusting the swing angle of the first material-picking cylinder 402. Similarly, the swing angle adjustment and limiting of the second material-picking cylinder 502 also adopts the same structure, which will not be described in detail here.

[0038] Regarding the sliding structure between the sliding bracket 2 and the fixed bracket 1, this embodiment also includes a sliding screw 201, a sliding screw nut 202, and a sliding screw motor 203. The sliding screw 201 is rotatably assembled with the fixed bracket 1, the sliding screw nut 202 is threadedly connected to the sliding screw 201, and the sliding screw motor 203 is assembled with the fixed bracket 1 and used to rotate the sliding screw 201. Specifically, the fixed end of the sliding screw motor 203 is connected to the fixed bracket 1, and the movable end of the sliding screw motor 203 is axially connected to the sliding screw 201. The sliding bracket 2 is assembled with the sliding screw nut 202, and the sliding bracket 2 and the fixed bracket 1 are connected by a slide rail slider. The rotation of the sliding screw 201 drives the movement of the sliding screw nut 202, so that the clamping mechanism clamps and transports the upper bead frame to the middle rail for installation, thereby improving the automation of the upper bead frame transfer.

[0039] Regarding the sliding assembly between the sliding bracket 2 and the fixed bracket 1, this embodiment also includes a sliding rail 204 and a sliding slider 205. The sliding rail 204 is connected to the fixed bracket and is arranged parallel to the sliding screw 201. The sliding rail 204 is located above the sliding screw 201. One side of the sliding slider 205 is slidably assembled with the sliding screw 201, and the other side of the sliding slider 205 is connected to the sliding bracket 2. Thus, under the drive of the sliding screw 201 and the sliding screw nut 202, the sliding bracket 2 moves back and forth along the axis of the sliding screw 201, thereby completing the transfer of the upper bracket.

[0040] It should be noted that this embodiment also includes a controller, which is used to electrically connect electrical components such as the first material picking cylinder 402, the first angle swing cylinder 403, the second material picking cylinder 502, the second angle swing cylinder 503, the lifting cylinder 301, the pitch adjusting screw motor 603, and the sliding screw motor 203, thereby achieving coordinated control.

[0041] The operating principle of this embodiment is as follows: Before operation, the position of the second clamping assembly is adjusted by the adjustable lead screw motor 603 to match the size of the upper bead frame to be installed. During operation, the sliding lead screw motor 203 rotates, so that the clamping mechanism is at one end of the sliding lead screw 201, i.e., the material picking position of the upper bead frame. The lifting cylinder 301 causes the material picking mechanism to move down, and the first material picking cylinder 402 and the second material picking cylinder 502 complete the clamping of the upper bead frame. After clamping is completed, the lifting cylinder 301 causes the material picking mechanism to move up, and then the sliding lead screw... The motor 203 rotates, causing the clamping mechanism to be positioned at the other end of the sliding screw 201, i.e., the mounting position of the upper ball frame and the middle rail. Under the push of the first angle swing cylinder 403 and the second angle swing cylinder 503, the upper ball frame held by the clamping mechanism is tilted. The lifting cylinder 301 causes the picking mechanism to move down, so that the upper ball frame makes inclined contact with the middle rail. Then, under the push of the first angle swing cylinder 403 and the second angle swing cylinder 503, the upper ball frame held by the clamping mechanism is returned to the upright position, thereby assembling the upper ball frame onto the middle rail.

[0042] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
