Description

Technical Field

[0001] The present application relates to the field of surface mounting technology, and in particular to a disassembly and assembly device for a knob assembly. Background Art

[0002] In the field of SMT (surface mount technology) motherboard patch production, the placement of components and shielding covers is a key step in the production process. To ensure that components and shielding covers do not shift during the flow line and before passing through the oven, operators traditionally need to lock and loosen the knobs on the carrier and fixture manually or using belt clamps.

[0003] However, these traditional methods have many shortcomings. First, manual operation is prone to fatigue in a high-frequency operation environment, which not only affects the work efficiency, but may also cause scratches on the carrier due to improper operation, or even damage the components on the PCB. At the same time, since it is impossible to lock the four knobs at the same time, it is easy to cause the PCB to shake, which in turn causes damage to the parts. In addition, the labor cost is high, and the operation stability is difficult to guarantee, which has a direct impact on the production yield.

[0004] In the related technology, some equipment uses belt-driven rotation, which has achieved automation to a certain extent, but belt wear and displacement problems frequently occur, resulting in insufficient equipment stability. This not only increases equipment maintenance costs, but also easily causes product damage, deformation and other problems, resulting in unstable product quality, and may also cause production interruptions, affecting overall production efficiency.

[0049] Referring to FIG. 1 to FIG. 8 , FIG. 1 to FIG. 8 respectively show a schematic diagram of the structure of the disassembly and assembly device of the knob assembly 20 in an embodiment of the present application and a schematic diagram of the structure of each component.

[0050] 1 , an embodiment of the present application provides a disassembly and assembly device for a knob assembly 20 , including a frame 1 , a knob disassembly and assembly mechanism 3 , a pushing mechanism 4 and a lifting mechanism 5 .

[0051] The frame 1 is the supporting structure of the entire disassembly and assembly device, and is made of high-strength steel to ensure the stability and durability of the device. A space for installing a fixture 2 is provided inside the frame 1. The fixture 2 is placed inside the frame 1 and is used to fix the shielding cover to be disassembled and the knob assembly 20 thereon.

[0052] In this embodiment, two sets of knob assemblies 20 are respectively disposed on both sides of the clamp 2 .

[0053] The knob assembly and disassembly mechanism 3 is connected to the knob assembly 20 and is used to implement the disassembly and assembly operation of the knob assembly 20 .

[0054] The pushing mechanism 4 is connected to the knob disassembly mechanism 3 and is used to push the knob disassembly mechanism 3 to rotate. The pushing mechanism 4 includes a pushing cylinder 42 and a transmission device. The pushing cylinder 42 provides power, which is converted into rotational motion through the transmission device, thereby driving the knob assembly 20 to rotate.

[0055] In this embodiment, the pushing mechanism 4 is bidirectionally driven and can control the two sets of knob assemblies 20 to rotate synchronously in opposite directions. For example, one set of knob assemblies 20 rotates clockwise and the other set of knob assemblies 20 rotates counterclockwise. The rotation direction of the knob assemblies 20 can be adaptively adjusted according to specific usage requirements.

[0056] The lifting mechanism 5 is connected to the pushing mechanism 4, and is used to drive the knob disassembly and assembly mechanism 3 to lift and lower, so that the knob disassembly and assembly mechanism 3 can move in the vertical direction, thereby squeezing or releasing the knob assembly 20. In this embodiment, the lifting mechanism 5 uses a screw rod 50 as a power source, and the lifting and lowering of the knob disassembly and assembly mechanism 3 is achieved by rotating the screw rod 50.

[0057] As shown in Figures 3 and 4, Figures 3 and 4 are schematic diagrams of the structure of the clamp 2 in an embodiment of the present application. In some embodiments, the bottom surface of the clamp 2 is provided with two knob grooves 21, and the extension directions of the two knob grooves 21 are perpendicular to each other; the knob assembly 20 is embedded in the knob grooves 21.

[0058] Specifically, two knob grooves 21 are provided on the bottom surface of the clamp 2. The extension directions of the two knob grooves 21 are perpendicular to each other, that is, the requirement of a single rotation of the knob by 90 degrees is met.

[0059] In the specific implementation process, the shielding cover to be disassembled is placed on the clamp 2 and fixed with the clamp 2. The lifting mechanism 5 is started to lower the knob disassembly mechanism 3 to a position in contact with the knob assembly 20. At the same time, the two groups of knob assemblies 20 are pressed down so that they protrude from the bottom of the clamp 2. The pushing mechanism 4 is started to drive the knob disassembly mechanism 3 to rotate. The left group of knob assemblies 20 rotates 90 degrees clockwise, and the right group of knob assemblies 20 rotates 90 degrees counterclockwise. After the rotation is completed, the lifting mechanism 5 is started to raise the knob disassembly mechanism 3 so that the knob assembly 20 falls into the knob slot 21 of the clamp 2.

[0060] Send the fixture 2 into the flow line or furnace equipment. After the furnace is completed, send the fixture 2 back to the disassembly and assembly device. Repeat the above pressing steps. Start the pushing mechanism 4 and turn the left and right sets of knob assemblies 20 back to 0 degrees. Slowly start the lifting mechanism 5 to slowly lift the knob assembly 20 and release the clamp 2. After the disassembly and assembly is completed, remove the disassembled shielding cover and the knob assembly 20 thereon from the fixture 2.

[0061] As described above, through the above-mentioned automated operation, the efficiency of disassembly and assembly of the knob assembly 20 is significantly improved. In addition, the entire disassembly and assembly process can be realized through simple control, the overall structure is simple, the operation is convenient, the knob assembly 20 is accurately controlled, manual operation is reduced, the risk of accidents caused by misoperation is reduced, and production safety is improved.

[0062] 2 and 5 , which are respectively another schematic diagram of the assembly and disassembly device of the knob assembly 20 in an embodiment of the present application and a schematic diagram of the structure of the pushing mechanism 4. In some embodiments, the pushing mechanism 4 includes a mounting frame 40, a pushing plate 41 and a pushing cylinder 42.

[0063] Specifically, the mounting frame 40 is the basic supporting structure of the entire pushing mechanism 4 and is fixed at an appropriate position in the frame 1 to ensure that the entire mechanism can work stably.

[0064] The mounting frame 40 is located directly above the fixture 2 and is connected to the lifting mechanism 5. The lifting mechanism 5 is responsible for driving the mounting frame 40 to rise and fall relative to the fixture 2 so as to adjust the relative position between the pushing mechanism 4 and the fixture 2.

[0065] The pushing plate 41 is disposed on a side of the mounting frame 40 close to the clamp 2 .

[0066] Specifically, the shape and size of the push plate 41 are adaptively adjusted according to specific usage requirements to ensure that it can provide stable support and can effectively contact the knob disassembly and assembly mechanism 3 when moving, thereby driving it to rotate.

[0067] The pushing cylinder 42 is disposed in the mounting frame 40 and connected to the pushing plate 41 .

[0068] Specifically, the push cylinder 42 is a power source for driving the push plate 41 to move, is installed inside the mounting frame 40, and is connected to the push plate 41 through a piston rod, so as to push the push plate 41 to move and drive the knob disassembly mechanism 3 to rotate.

[0069] In this embodiment, the push cylinder 42 can be selected to be pneumatic, hydraulic or electric, depending on the overall design and performance requirements of the device. In this embodiment, the pneumatic push cylinder 42 is used, and compressed air is used as the working medium. After receiving the control signal, it can quickly and accurately push the piston rod to extend or retract, thereby driving the push plate 41 to move in the horizontal direction.

[0070] As described above, the pushing mechanism 4 is easy to operate and can realize automatic assembly and disassembly of the knob, which greatly improves work efficiency and accuracy.

[0071] 7 is another schematic diagram of the structure of the pushing mechanism 4 in an embodiment of the present application. In some embodiments, the pushing mechanism 4 further includes a slide groove 43 and a slide rail 44.

[0072] Specifically, the slide groove 43 is arranged on one side of the mounting frame 40 close to the push plate 41. The slide groove 43 is a long strip groove, and its shape and size are precisely calculated to ensure a close fit with the slide rail 44. The slide groove 43 is used to guide the push plate 41 to move smoothly along a predetermined path, prevent it from deviating from the track, and improve the stability and accuracy of the push mechanism 4.

[0073] The slide rail 44 is fixed on the push plate 41 and matches the shape of the slide groove 43. When the push plate 41 moves, the slide rail 44 slides along the slide groove 43, which improves the stability of the movement of the push plate 41, reduces friction and wear, and prolongs the service life of the mechanism.

[0074] 5 and 6 are schematic diagrams of the structure of the push mechanism 4 in an embodiment of the present application. In some embodiments, a set of racks 45 are respectively provided on both sides of the push plate 41. The knob disassembly mechanism 3 includes a gear 30 meshing with the rack 45 for transmission.

[0075] Specifically, the racks 45 are disposed on both sides of the push plate 41 , and the racks 45 are longitudinally long in the moving direction of the push plate 41 , ensuring that the push plate 41 has a sufficiently long moving stroke, thereby ensuring that the knob assembly 20 has a sufficient rotation angle.

[0076] In this embodiment, the rack 45 is composed of a series of equally spaced teeth, which match the teeth of the gear 30 for transmitting power. The design of the rack 45 not only improves the accuracy of the transmission, but also enhances the stability of the push plate 41 during the movement.

[0077] The two groups of gears 30 are respectively arranged on both sides of the rack 45, and the two groups of gears 30 rotate in opposite directions.

[0078] In the specific implementation process, when the knob assembly 20 needs to be disassembled, the lifting mechanism 5 first lowers the pushing mechanism 4 to a position close to the clamp 2. Then, the pushing cylinder 42 receives the start signal, and its piston rod extends, pushing the pushing plate 41 to move along a predetermined path. During the movement, the racks 45 on both sides of the pushing plate 41 are tightly meshed with the gears 30 in the knob disassembly mechanism 3, transmitting power to the gears 30, causing them to start rotating. The rotation of the gears 30 drives the corresponding components of the knob disassembly mechanism 3, thereby realizing the tightening or loosening operation of the knob assembly 20.

[0079] As shown in Figures 8 and 9, Figures 8 and 9 are schematic diagrams of the structure of the knob disassembly mechanism 3 and the structure of the buckle 31 in an embodiment of the present application. In some embodiments, the knob disassembly mechanism 3 further includes a buckle 31, one end of which is connected to the gear 30, and the other end of which has a recessed portion 32 that is engaged with the knob assembly 20.

[0080] Specifically, the buckle 31 is a key component of the knob disassembly mechanism 3, one end of which is connected to the gear 30, and the other end of which has a recessed portion 32 that is engaged with the knob assembly 20. In this embodiment, the recessed portion 32 is designed as a concave strip-shaped groove, and its size and shape match the corresponding part on the knob assembly 20 to ensure that the buckle 31 can be firmly engaged with the knob assembly 20, prevent it from falling off or moving during the disassembly process, and improve stability and reliability.

[0081] In one embodiment, the knob disassembly mechanism 3 further includes a fixing ring 33 , and the fixing ring 33 is disposed on the mounting frame 40 .

[0082] Specifically, the fixing ring 33 is circular in shape, and the middle thereof is a perforated portion capable of accommodating the buckle 31. One end of the buckle 31 passes through the central hole of the gear 30 and the perforated portion of the fixing ring 33, respectively, and is fixedly mounted on the mounting frame 40. The existence of the fixing ring 33 enhances the connection stability between the buckle 31 and the mounting frame 40, prevents the buckle 31 from accidentally falling off or moving during the disassembly process, and improves reliability.

[0083] As described above, the knob disassembly and assembly mechanism 3 significantly enhances the connection stability between the buckle 31 and the mounting frame 40 by setting a fixing ring 33 to cooperate with the buckle 31, thereby improving the reliability and efficiency of the knob disassembly and assembly operation, and enhancing the durability and safety of the overall device.

[0084] As shown in FIG10 , FIG10 is a schematic diagram of the structure of a knob assembly 20 in an embodiment of the present application. In some embodiments, the knob assembly 20 includes a top block 200 , a pull rod 201 , a spring 202 and a fixing block 203 .

[0085] Specifically, the top block 200 is set to a shape that matches the recessed portion 32 preset on the buckle 31, such as a rectangle, to ensure that the top block 200 can be accurately and firmly clamped in the recessed portion 32. The top block 200 is made of a wear-resistant material with a certain elasticity, such as stainless steel or hard plastic, to provide good durability and hand feel. The top block 200 is the direct contact part between the knob assembly 20 and the buckle 31. When the buckle 31 is pressed down or rotated, the knob assembly 20 is squeezed to move downward or rotate to achieve a locking or releasing operation.

[0086] The pull rod 201 is in the shape of a slender rod, one end of which is connected to the top block 200, and the other end is designed as a slender rod portion, which passes through the reserved hole on the clamp 2 and is connected to the fixed block 203. The pull rod 201 is made of high-strength stainless steel or alloy steel to ensure sufficient strength and corrosion resistance. The pull rod 201 serves as a bridge connecting the top block 200 and the fixed block 203, transmitting the applied rotational force to move or rotate the fixed block 203.

[0087] The spring 202 is sleeved on the pull rod 201 and is located between the top block 200 and the fixed block 203. The compression spring 202 is selected to have good elasticity and restoring force. The main function of the spring 202 is to provide a locking force. When the knob is squeezed, the spring 202 is compressed. When the knob is rotated to a certain angle, the knob is no longer compressed, and the spring 202 releases its elastic force to assist the knob to return to its initial position.

[0088] The fixing block 203 is installed at the bottom end of the pull rod 201, and the bottom of the fixing block 203 is set to a plane to ensure close contact with the bottom surface of the clamp 2 to increase stability. Further, the fixing block 203 is an embedded structure matching the knob groove 21, and the fixing block 203 has a certain protrusion, which can be tightly and stably embedded in the corresponding knob groove 21.

[0089] As described above, efficient and stable locking and releasing functions are achieved through the precise coordination of the top block 200, the pull rod 201, the spring 202 and the fixing block 203. The above structure is simple, easy to operate, and durable, and is suitable for a variety of occasions requiring quick connection, locking or adjustment.

[0090] As shown in FIG. 2 , FIG. 2 is a schematic diagram of the structure of the disassembly and assembly device of the knob assembly 20 in an embodiment of the present application. In some embodiments, the lifting mechanism 5 includes a screw rod 50 and a screw rod sleeve 51, the screw rod 50 is vertically arranged in the frame 1; the screw rod sleeve 51 is sleeved on the screw rod 50 and connected to the mounting frame 40.

[0091] Specifically, the screw rod 50 is vertically arranged inside the frame 1, with one end fixed to the top of the frame 1 and the other end supported at the bottom of the frame 1 by a bearing, so as to ensure that the screw rod 50 can rotate freely and maintain axial stability. The inner hole of the screw rod sleeve 51 is threadedly matched with the screw rod 50, so as to ensure that the screw rod 50 can be lifted and lowered smoothly when rotating. The outer wall of the screw rod sleeve 51 is connected to the mounting frame 40 by bolts or welding, so that the mounting frame 40 can be lifted and lowered with the lifting and lowering of the screw rod sleeve 51.

[0092] In one embodiment, a driving mechanism 6 is further included. The driving mechanism 6 is a driving motor 60 . An output end of the driving motor 60 is connected to the screw rod 50 by belt transmission.

[0093] Specifically, the output end of the drive motor 60 is connected to one end of the lead screw 50 through a synchronous belt to realize belt transmission. The drive motor 60 can adopt a DC brushless motor, which has the advantages of high efficiency, low noise, and a wide speed regulation range. The synchronous belt has the characteristics of accurate transmission and no slip, which can ensure the transmission efficiency between the drive motor 60 and the lead screw 50. When the drive motor 60 is started, its output end drives the lead screw 50 to rotate through the synchronous belt. Since the lead screw 50 and the lead screw sleeve 51 are threaded, the lifting speed of the lead screw sleeve 51 is proportional to the rotation speed of the lead screw 50. By accurately controlling the speed and direction of the motor, the precise lifting and positioning of the mounting bracket 40 can be achieved.

[0094] As described above, the precise lifting and positioning of the mounting frame 40 is achieved through the cooperation of the screw rod 50 and the screw rod sleeve 51 and the driving of the driving motor 60. The device has the advantages of simple structure, accurate transmission, and stable lifting, and meets the different height working requirements in automated production lines or assembly equipment.

[0095] In this embodiment, an operating method of a disassembly and assembly device applied to the knob assembly 20 is provided.

[0096] Specifically, the drive motor 60 starts to rotate, and drives the screw rod 50 to rotate through the belt. The screw rod sleeve 51 is fixed on the lifting module and moves downward as the screw rod 50 rotates. When the buckle 31 contacts the upper surface of the knob assembly 20 on the fixture 2, continue to press down. Until the bottom of the knob assembly 20 protrudes 5mm from the lower surface of the carrier, the drive motor 60 stops rotating. The push cylinder 42 is opened, and the push plate 41 moves smoothly by 10mm through the linear slide rail 44. The gear 30 structure moves with the push plate 41, driving the buckle 31 to rotate 90 degrees. Among them, the left knob assembly 20 rotates clockwise and the right knob assembly 20 rotates counterclockwise to offset the force in the rotation direction. The drive motor 60 rotates in the opposite direction, and the lifting mechanism 5 rises. The knob assembly 20 falls into the buckle 31 groove of the carrier. At this time, the driving motor 60 continues to rise and returns to the initial position, pushing the cylinder 42 to close. At this time, the push plate 41 drives the gear 30 structure and the buckle 31 to return to the initial 0 degree position, thereby completing the installation process of the knob.

[0097] Open the push cylinder 42, and the push plate 41 drives the gear 30 structure and the buckle 31 to rotate to the 90-degree position. The drive motor 60 drives the screw 50 to rotate, and the lifting mechanism 5 moves downward. After the buckle 31 contacts the surface of the knob assembly 20, it continues to press down until the bottom of the knob assembly 20 protrudes 5mm from the bottom of the carrier. Close the push cylinder 42, and the buckle 31 on the gear 30 structure rotates 90 degrees in the opposite direction to return to the 0-degree position. The drive motor 60 rotates in the opposite direction, and the lifting mechanism 5 rises. The knob assembly 20 on the carrier and the fixture 2 is separated until it returns to the initial position and stops rotating, completing the disassembly process of the knob.

[0098] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0099] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
