Description

Technical Field

[0001] This application relates to the field of processing equipment technology, and in particular to a convenient and fast automatic screw loosening machine. Background Technology

[0002] Currently, screws are frequently used to connect components during the assembly process. This is especially true for auxiliary switches, which are part of the main switch and can be used as combination switches or changeover switches. In existing technology, auxiliary switches include a base and multiple terminals arranged on the base, with each terminal corresponding to a screw screwed into it for crimping the wires.

[0003] Regarding the aforementioned technologies, when wiring the purchased auxiliary switch parts, since the screws on the terminals are mostly in a locked state, it is necessary to manually loosen the screws before subsequent wiring work can be carried out, resulting in high labor intensity. Summary of the Invention

[0004] To facilitate the automatic loosening of screws on parts and reduce labor intensity, this application provides a convenient and fast automatic screw loosening machine.

[0005] The present application provides a convenient and fast automatic screw loosening machine using the following technical solution:

[0006] A convenient and fast automatic screw loosening machine includes: a longitudinal sliding assembly, on which a part is fixed, the longitudinal sliding assembly being used to drive the part to move and adjust along the longitudinal direction; and a transverse sliding assembly, on which an electric screwdriver is slidably mounted, the electric screwdriver being located above the longitudinal sliding assembly, the electric screwdriver being adjusted and slidable along the height direction, and the transverse sliding assembly being provided with a driving component for driving the electric screwdriver to move up and down.

[0007] By adopting the above technical solution, the part can be fixed to the longitudinal sliding component and moved along the longitudinal direction by the longitudinal sliding component. The transverse sliding component can move the electric screwdriver along the transverse direction and move it directly above the part. Then, the drive component drives the electric screwdriver to move up and down, so that when the electric screwdriver moves down, it can approach and cooperate with the screw on the part. Finally, the electric screwdriver loosens the screw. Moreover, by repeating the above action, the position of the part can be adjusted by the longitudinal sliding component, and the position of the electric screwdriver can be adjusted by the transverse sliding component, so that the electric screwdriver continues to move above the next screw that needs to be loosened, and the next screw can be automatically loosened. This achieves the effect of automatically loosening the screws on the part and reducing labor intensity.

[0008] Preferably, the electric screwdriver includes a motor and an electric screwdriver bit, the electric screwdriver bit is connected to the motor for transmission, and the motor drives the screwdriver to rotate; the lateral sliding assembly is provided with a sleeve, and the electric screwdriver bit is inserted into the sleeve.

[0009] By adopting the above technical solution, the electric screwdriver bit can be rotated under the drive of the motor, and the electric screwdriver bit can be inserted into the head slot of the screw, thereby loosening the screw.

[0010] Preferably, the sleeve is vertically arranged, and a first hole section and a second hole section are coaxially arranged inside the sleeve and communicate with each other. The first hole section is located near the upper end of the sleeve, and the inner diameter of the first hole section is adapted to the outer diameter of the electric screwdriver bit. The second hole section is located near the lower end of the sleeve, and the inner diameter of the second hole section is adapted to the outer diameter of the screw head on the part. When the sleeve moves downward and closer to the part, the screw head on the part is located in the second hole section.

[0011] By adopting the above technical solution, when the electric screwdriver bit moves up and down through the sleeve, the first hole section can limit the electric screwdriver bit and improve the stability of the electric screwdriver bit when rotating; and when the sleeve moves down, the second hole section of the sleeve can cover the head of the screw, which can limit the screw in the horizontal direction, making the screw more stable when loosening.

[0012] Preferably, a chamfer is provided at the junction of the bottom end of the sleeve and the inner wall of the second hole section.

[0013] By adopting the above technical solution, the chamfered part has a guiding function, making it easier for the sleeve to cover the screw head.

[0014] Preferably, the inner diameter of the first hole segment is smaller than the inner diameter of the second hole segment, and a ring-shaped stepped surface is formed between the junction of the first hole segment and the second hole segment.

[0015] By adopting the above technical solution, since the screw may be attracted or stuck to the screwdriver bit when it moves upward after the screw is tightened, the stepped surface can block the screw head and restrict the screw from moving upward, thus separating the screw from the screwdriver bit.

[0016] Preferably, an annular elastic ring is fixed inside the sleeve at the position of the stepped surface. The elastic ring is coaxially arranged with the sleeve, and the inner diameter of the elastic ring is smaller than the inner diameter of the first hole section. When the electric screwdriver bit moves up and down, it passes through the elastic ring, and the inner wall of the elastic ring is close to the outer side of the electric screwdriver bit.

[0017] By adopting the above technical solution, when the outer diameter of the electric screwdriver bit is close to the outer diameter of the screw head, in order to adapt to the screw head and the electric screwdriver bit, the inner diameters of the first hole section and the second hole section are not much different. Therefore, the interval between the inner and outer diameters of the annular stepped surface is small, which may cause the screw head to get stuck in the first hole section when it moves upward. However, by using an elastic ring with a certain deformation capacity, when the electric screwdriver bit passes through the elastic ring, the inner wall of the elastic ring can stick tightly to the outer wall of the electric screwdriver bit. Therefore, when the electric screwdriver bit moves the screw upward, the elastic ring can better block the screw head, reduce the screw head from passing through the elastic ring and entering the first hole section, and ensure that the screw can be separated from the electric screwdriver bit.

[0018] Preferably, the lateral sliding assembly includes a horizontally arranged first linear module, the first linear module having a lateral slider that can slide and adjust along the horizontal lateral direction, and the drive member and the electric screwdriver are disposed on the lateral slider.

[0019] By adopting the above technical solution, the first linear mold can drive the horizontal slider to move along the horizontal direction, thereby driving the drive component and the electric screwdriver to slide along the horizontal direction.

[0020] Preferably, the driving component is a vertical cylinder, a connecting block is provided on the side of the motor, the piston rod of the vertical cylinder passes through the connecting block, limit blocks are provided on both sides of the piston rod in the direction of the connecting block, and an elastic element is sleeved on the piston rod, the elastic element being located between the connecting block and the limit block at the upper position.

[0021] By adopting the above technical solution, when the piston rod of the vertical cylinder moves downward, the elastic element pushes the connecting block downward. When the lower end of the electric screwdriver bit contacts the screw head and the piston rod continues to move downward, the elastic element is compressed. At this time, the end of the electric screwdriver bit can elastically press against the screw. Therefore, when the electric screwdriver bit starts to rotate, it ensures that the electric screwdriver bit can be better inserted into the slot of the screw head.

[0022] Preferably, a third linear module is provided on the horizontal slider along the height direction, the third linear module is slidably connected to a connecting plate, the motor is slidably connected to the connecting plate along the height direction, and the driving component and the sleeve are disposed on the connecting plate.

[0023] By adopting the above technical solution, the third linear module can drive the connecting plate to slide along the height direction, thereby synchronously driving the motor, sleeve and drive component to move up and down, so that the electric screwdriver can get closer to the parts and improve the applicability.

[0024] Preferably, the longitudinal sliding assembly is provided with a positioning fixture, and the part is fixed to the positioning fixture.

[0025] By adopting the above technical solution and using positioning fixtures, the parts can be fixed, so that the parts remain stable on the longitudinal sliding assembly.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] (1) By setting the cooperation between the longitudinal sliding component, the transverse sliding component, the drive component and the electric screwdriver, the position of the part and the electric screwdriver can be adjusted so that the electric screwdriver and the screw on the part are opposite each other and loosened, so as to facilitate the automatic loosening of the screw on the part and reduce the labor intensity.

[0028] (2) By setting a sleeve, the sleeve includes a first hole section and a second hole section. The first hole section can improve the stability of the electric screwdriver bit when in use, and the second hole section can limit the movement of the screw in the horizontal direction, thereby improving the stability of the electric screwdriver bit when loosening the screw.

[0029] (3) By setting an elastic ring, the screw head can be reduced from getting stuck in the second hole section, ensuring that the screw and the electric screwdriver bit are separated. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0036] This application discloses a convenient and fast automatic screw loosening machine. (Refer to...) Figure 1 The screw loosening machine includes a longitudinal sliding assembly 1, a transverse sliding assembly 2, a frame 3, an electric screwdriver 4, a positioning fixture 5, and a drive component 6.

[0037] The frame 3 includes a base 31 and a gantry 32. The base 31 is rectangular and shell-shaped. The gantry 32 is fixed to the long side of the base 31, with its opening facing downwards and both ends fixed to the base 31. A transverse sliding assembly 2 is installed along the length of the upper end of the gantry 32. In this embodiment, the long side of the base 31 is in the transverse direction, and the wide side is in the longitudinal direction. The transverse sliding assembly 2 includes a horizontally arranged first linear module. The linear module is a prior art technology and includes a synchronous belt type module, a lead screw type module, or a linear motor type module. In this embodiment, the first linear module is selected as a lead screw type module. The first linear module is provided with a transverse slider 7 that slides and adjusts along the horizontal transverse direction. A connecting plate 8 is vertically installed on the transverse slider 7, and an electric screwdriver 4 is vertically slidably installed on the connecting plate 8. The drive unit 6 is installed on the side of the connecting plate 8. The drive unit 6 is a vertical cylinder, which is set vertically with its piston rod pointing downwards and connected to one side of the electric screwdriver 4. The vertical cylinder drives the electric screwdriver 4 to move up and down. The first linear module drives the horizontal slider 7, the electric screwdriver 4, and the drive unit 6 to slide and adjust synchronously in the horizontal direction.

[0038] Reference Figure 1 and Figure 2 The longitudinal sliding assembly 1 is fixed to the upper surface of the base 31 and is arranged along the short side of the base 31. The longitudinal sliding assembly 1 is located below the transverse sliding assembly 2. The longitudinal sliding assembly 1 includes a second linear module, which is also selected as an existing lead screw type module. A longitudinal slider 9, which is slidably arranged on the second linear module, is adjustable along the longitudinal direction. The positioning fixture 5 is arranged on the upper surface of the longitudinal slider 9, and the part is fixed to the positioning fixture 5 to position and fix the part. When the longitudinal slider 9 slides, it can drive the positioning fixture 5 and the part to move synchronously, so that the screws on the part that need to be loosened are vertically aligned with the electric screwdriver 4.

[0039] In this embodiment, the positioning fixture 5 is used for the auxiliary switch 10. The positioning fixture 5 includes a fixing part 51, a moving part 52, and a clamping cylinder 53. The fixing part 51 is fixed to one side of the longitudinal slider 9. A plurality of positioning grooves 22 are spaced apart on the fixing part 51. One end of the positioning groove 22 extends to the outer periphery of the fixing part 51, so that one end of the positioning groove 22 is completely open. The base of the auxiliary switch 10 is engaged with the positioning groove 22 and extends out of the positioning groove 22 from the open end of the positioning groove 22. The moving part 52 is slidably disposed on one side of the open end of the positioning groove 22. The moving part 52 moves in a direction close to or away from the open end of the positioning groove 22. The clamping cylinder 53 is used to drive the moving part 52 to move. When the auxiliary switch 10 is engaged with the opening of the positioning groove 22, the clamping cylinder 53 drives the moving part 52 to abut against the end of the auxiliary switch 10 extending out of the positioning groove 22, thereby achieving the positioning and fixing of the auxiliary switch 10.

[0040] In other embodiments, the positioning fixture 5 can be adjusted and adapted to fit the specific shape of the part, depending on the different parts.

[0041] In some embodiments, two longitudinal sliding components 1 are arranged parallel to each other and spaced apart. Therefore, when the electric screwdriver 4 loosens the screws on one of the positioning fixtures 5, the other positioning fixture 5 can be used to install or remove parts. After the screws on the first positioning fixture 5 are loosened, the work can continue without much waiting time. This allows two processing stations to work alternately, improving processing efficiency.

[0042] In some embodiments, refer to Figure 3 The electric screwdriver 4 includes a motor 41 and an electric screwdriver bit 42. The motor 41 is vertically slidably mounted on the connecting plate 8. The motor 41 slides stably on the connecting plate 8 via guide rails and guide blocks. The electric screwdriver bit 42 is rod-shaped and is connected to the drive shaft of the motor 41. The motor 41 drives the screwdriver to rotate. The electric screwdriver bit 42 is vertically detachable and can be installed. The electric screwdriver bit 42 can include slotted, Phillips, hexagonal, and Y-type heads according to different head shapes. In this embodiment, a Phillips head electric screwdriver bit 42 is selected.

[0043] In some embodiments, a sleeve 11 is vertically fixed on the side of the connecting plate 8 where the motor 41 is installed. One side of the sleeve 11 is detachably locked to the connecting plate 8 by screws or bolts. The sleeve 11 is vertically arranged, and the sleeve 11 and the electric screwdriver bit 42 are located on the same vertical line. The electric screwdriver bit 42 is inserted into the sleeve 11. The sleeve 11 can limit the electric screwdriver bit 42, improve the stability of the electric screwdriver bit 42 when rotating, and make the electric screwdriver bit 42 more stable when loosening screws.

[0044] In some embodiments, refer to Figure 3 and Figure 4The sleeve 11 has a first hole section 12 and a second hole section 13 coaxially connected inside. The first hole section 12 is located near the upper end of the sleeve 11, and its inner diameter is adapted to the outer diameter of the electric screwdriver bit 42, allowing the electric screwdriver bit 42 to be loosened through the first hole section 12. The second hole section 13 is located near the lower end of the sleeve 11, and its outer diameter is adapted to the outer diameter of the screw head on the part. When the sleeve 11 moves downwards closer to the part, the drive component 6 drives the electric screwdriver 4 to move downwards, and the screw head on the part enters the second hole section 13, and the lower end of the electric screwdriver bit 42 enters the second hole section 13 and elastically abuts against the screw head. The second hole section 13 can cover the screw head, limiting the horizontal movement of the screw. Therefore, by simultaneously limiting the screw and the electric screwdriver bit 42, the electric screwdriver bit 42 is more stable when loosening screws, ensuring that each screw is loosened more effectively and reducing the possibility of some screws not being loosened.

[0045] Since the outer diameter of the screw head is mostly larger than the outer diameter of the electric screwdriver bit 42, the inner diameter of the first hole section 12 is smaller than the inner diameter of the second hole section 13. A ring-shaped stepped surface 14 is formed inside the sleeve 11 between the junction of the first hole section 12 and the second hole section 13. When the electric screwdriver bit 42 moves upward after the screw is tightened, the screw may be attracted or stuck to the lower end of the electric screwdriver bit 42 and move upward synchronously. Therefore, when the screw moves upward with the electric screwdriver bit 42, the stepped surface 14 can block the outer periphery of the screw head, restricting the screw from continuing to move upward, so that the screw separates from the electric screwdriver bit 42 and falls off.

[0046] In some embodiments, an annular elastic ring 15 is fixed inside the sleeve 11 at the position of the stepped surface 14. The elastic ring 15 is made of rubber and has a certain elastic deformation capability. The elastic ring 15 is coaxially arranged with the sleeve 11. The inner diameter of the elastic ring 15 is smaller than the inner diameter of the first hole segment 12. The outer side of the elastic ring 15 is fixed to the inner wall of the second hole segment 13. When the electric screwdriver bit 42 moves up and down, it passes through the elastic ring 15. The inner wall of the elastic ring 15 is close to the outer side of the electric screwdriver bit 42. The elastic ring 15 can reduce the impact and wear caused by the screw head on the stepped surface 14, and at the same time reduce the noise generated by the screw directly colliding with the stepped surface 14.

[0047] Furthermore, when the outer diameters of the electric screwdriver bit 42 and the screw head are relatively small, the inner diameters of the first hole segment 12 and the second hole segment 13 are also relatively small. The interval between the inner and outer diameters of the stepped surface 14 is also designed to be relatively low, which may cause the screw head to get stuck in the first hole segment 12. At this time, the inner wall of the elastic ring 15 can completely adhere to the outer side of the electric screwdriver bit 42, blocking the screw better than the stepped surface 14, reducing the possibility of the screw getting stuck in the first hole segment 12 through the elastic ring 15, so that the electric screwdriver bit 42 is separated from the screw. Moreover, when the electric screwdriver bit 42 moves the screw upward and the screw head hits the elastic ring 15, the elastic ring 15 can provide a downward elastic force to the screw head, further ensuring that the screw is better bounced off the sleeve 11.

[0048] In some embodiments, the sleeve 11 has a certain thickness, and a chamfer 16 is processed at the junction of the bottom end of the sleeve 11 and the inner wall of the second hole section 13. The chamfer 16 can be a rounded corner or a right angle. In this embodiment, a right angle is selected. The chamfer 16 can play a guiding role, so that the screw head can better enter the second hole section 13.

[0049] A connecting block 17 is fixed to the outside of the motor 41. The piston rod of the vertical cylinder passes through the connecting block 17. Limiting blocks 18 are fixed on the piston rod in the upper and lower directions of the connecting block 17. The piston rod has an external thread. The limiting block 18 is a nut screwed to the piston rod. An elastic element 19 is sleeved on the piston rod. The elastic element 19 is a spring. The elastic element 19 is located between the connecting block 17 and the limiting block 18 at the upper position.

[0050] When the vertical cylinder drives the motor 41 to its lowest position, the distance between the connecting block 17 and the upper limiting block 18 is minimal, and the two ends of the spring are compressed, allowing the lower end of the electric screwdriver bit 42 to elastically press against the screw head. When the electric screwdriver bit 42 rotates to correspond with the slot of the screw head, the electric screwdriver bit 42 can elastically engage in the slot, ensuring that the electric screwdriver bit 42 and the screw cooperate with each other. When the piston of the driving cylinder 6 drives the motor 41 to move upward, the compression of the spring gradually decreases, and the distance between the connecting block 17 and the upper limiting block 18 increases.

[0051] In some embodiments, a third linear module 20 is mounted on the horizontal slider 7 along the height direction. The third linear module 20 is also selected as an existing lead screw type module. The third linear module 20 is equipped with a vertical slider 21 for sliding adjustment. The connecting part is fixed to the vertical slider 21. Therefore, the electric screwdriver 4, the socket 11 and the drive unit 6 can be moved synchronously along the height direction by the third linear module 20 to more accurately control the height position of the electric screwdriver 4.

[0052] The implementation principle of a screw loosening method according to an embodiment of this application is as follows: During operation, the auxiliary switch 10 is fixed on the positioning fixture 5; the longitudinal sliding component 1 drives the auxiliary switch 10 to slide along the longitudinal direction, while the transverse sliding component 2 drives the electric screwdriver 4 to move directly above the auxiliary switch 10. Then, the third linear module 20 synchronously drives the connecting plate 8, the sleeve 11, and the electric screwdriver 4 to move downward, so that the second hole section 13 of the sleeve 11 covers the screw head; then the driving component 6 drives the electric screwdriver 4 to move downward, so that the electric screwdriver bit 42 passes through the first hole section 12 and the elastic ring 15 and enters the second hole section 13, and elastically abuts against the screw head in the second hole section 13; then the motor 41 drives the electric screwdriver bit 42 to rotate, and when the electric screwdriver bit 42 rotates, it can be embedded in the groove of the screw head to automatically loosen the screw. The above steps are repeated so that the electric screwdriver bit 42 is vertically aligned with the next screw and cooperates to loosen it, thereby realizing the effect of automatically loosening the screws on the parts and reducing labor intensity.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
