Description

Technical Field

[0001] The invention belongs to the technical field of fastener assembly, and in particular relates to an automatic assembly device for fastener roller feeding. Background Art

[0002] In the field of high-end equipment manufacturing, industrial robots, special operation robots and other equipment need to perform special assembly operations during the production process. The equipment casing is fixed by fasteners. At present, fasteners are usually loaded by rollers, and the arranged screws are sorted and sent to the assembly position through slide rails; but the screws loaded by rollers are prone to abnormal arrangement postures, causing material jamming, which in turn affects subsequent tightening and installation operations. The existing technology mainly uses vibration to solve the jamming problem, but once the material enters the slide rail, it can no longer be acted on. Due to multiple factors such as the slide rail height, slope and material, the material entering the slide rail still has abnormal posture problems, and the existing technology often does not take remedial measures for the slide rail, which not only affects the loading of materials, but also reduces the reliability of the equipment, and seriously restricts the working efficiency of the assembly device. Summary of the invention

[0006] As a preferred solution of the present invention, a mounting groove is provided at the bottom of the fixing tube, fixing grooves are provided on the four sides of the inner wall of the fixing tube, the fixing tube is movably clamped in the mounting groove, a clamping groove is provided on the outer surface of the fixing tube, and a spring and a clamping column are movably clamped inside the clamping groove.

[0007] As a preferred solution of the present invention, the fixing tube is made of a permanent magnet block, the mounting groove and the mounting tube are both designed in a "cross" shape, and the two ends of the slot are elastically connected to the clamping column and the inner wall of the slot respectively.

[0008] As a preferred solution of the present invention, the damping strip is made of a rubber block, the shape of the damping strip is "U"-shaped, and the damping strip protrudes inwardly from the inner walls of the waiting trough and the assembly trough.

[0009] As a preferred solution of the present invention, the two ends of the spring 2 are elastically connected to the assembly plate and the transmission assembly block respectively, the two ends of the spring 1 are elastically connected to the movable plate and the assembly plate respectively, and the bottom of the movable plate can abut against the motor 2.

[0010] As a preferred solution of the present invention, the inner walls of the slide rail one and the slide rail two are both designed as a "T"-shaped cavity, the slide rail two is arranged on the front and rear sides of the inclined portion of the slide rail one, and the upper and lower openings of the slide rail two are respectively connected to the guide port and the return port.

[0011] As a preferred solution of the present invention, the cross-sectional shape of the guide plate in top view is "V"-shaped, and the guide plate is fixedly connected to the top of an inclined surface of the slide rail.

[0012] As a preferred solution of the present invention, the pulling force of the spring on the clamping column is smaller than the magnetic attraction force of the fixing tube on the clamping column, and the friction force between the mounting tube and the clamping column caused by the magnetic attraction is larger than the gravity of the mounting tube.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. The device has redesigned the slide rail 1 so that the device has the function of dynamic adjustment of the workpiece. A support frame is provided to provide rotational support for the roller. When the roller rotates, it generates an axial thrust to the right on the workpiece, pushing the workpiece to the right. A discharge port is opened on the right side of the support frame to throttle the number of workpieces passing through the discharge port. The small size design of the discharge port provides a probability that the workpiece enters the slide rail 1 in a normal posture. When a workpiece with an abnormal posture enters the slide rail 1, it will inevitably protrude upward from the upper surface of the slide rail 1. At this time, a guide plate is provided to block the protruding workpiece and guide it so that the workpiece is guided to the slide rail 2. After the diversion and movement, the posture of the workpiece is quickly adjusted and returns to the slide rail 1. This design enables the device to have a synchronous deviation correction function during the loading process, greatly improving the reliability of the device.

[0015] 2. The device is also designed with a damping strip in conjunction with the slide rail. When the workpiece that slides into the waiting trough and the assembly trough through the slide rail enters the position directly below the assembly part, the damping strip protrudes from the inner wall of the waiting trough and the assembly trough, so that the workpiece squeezes the damping strip and generates friction resistance to offset the impact force of the workpiece. When the first group of workpieces is assembled, the workpiece to be processed is just offset from the fixed cylinder by the friction resistance of the damping strip, avoiding the rigid jamming and collision of the assembly part and the fixed cylinder on the workpiece when tightening the assembly once, which helps to improve the safety of the device.

[0016] 3. The device also designs the assembly part and the fixed cylinder to be separate, so that different types of workpieces can be adapted with corresponding assembly parts. A "cross"-shaped installation groove is opened at the bottom of the fixed cylinder, which is used to magnetically clamp the installation cylinder, thereby facilitating replacement and disassembly. By opening a fixed groove on the inner wall of the installation groove, the centrifugal force generated by the rotation of the fixed cylinder and the installation cylinder driven by the second motor drives the clamping column to move toward one side of the fixed groove and clamp it into the fixed groove, thereby firmly clamping the installation cylinder and the fixed cylinder together, improving the stability of the device. When the second motor stops running, the clamping column is reset under the pulling force of the third spring, which is convenient for replacement and disassembly. This design greatly improves the working efficiency of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figures 1 to 8 As shown, an embodiment of the present invention provides an automatic assembly device for fastener roller feeding, including a base 1, a support frame 2, a roller 4 and a transmission assembly block 6, the roller 4 is rotatably installed inside the support frame 2, a motor 3 is installed inside the base 1, a transmission belt 5 is connected between the output shaft of the motor 3 and the roller 4, a discharge port 21 is provided on the right side of the support frame 2, a slide rail 7 is fixedly installed between the support frame 2 and the transmission assembly block 6, slide rails 8 are fixedly installed on both sides of the slide rail 7 in the transportation direction, a guide port 22 and a return port 23 are respectively provided on the surface of the slide rail 7, a guide plate 9 is fixedly installed on the top of the inclined surface of the slide rail 7, and the guide plate 9 is symmetrically arranged by two groups of inclined plates at the front and rear;

[0028] A material waiting slot 24 and an assembly slot 25 are respectively provided on the top of the transmission assembly block 6, and the inner walls of the material waiting slot 24 and the assembly slot 25 are fixedly connected with a damping strip 26. A plurality of guide columns 10 are fixedly installed on the top of the transmission assembly block 6, and a top plate 11 is installed on the top of the guide column 10, and a hydraulic cylinder 12 is installed on the bottom of the top plate 11, and a moving plate 13 is connected to the telescopic end of the hydraulic cylinder 12. A spring 14, an assembly plate 15 and a spring 2 16 located below the moving plate 13 are movably sleeved on the outer surface of the transmission assembly block 6, and the assembly plate 15 is elastically supported between the spring 14 and the spring 2 16. A motor 2 17 is installed on the top of the assembly plate 15, and a fixed cylinder 18 is fixedly installed on the output shaft of the motor 2 17, and a mounting cylinder 19 is movably clamped on the bottom of the fixed cylinder 18, and an assembly part 20 is fixedly installed on the bottom of the mounting cylinder 19;

[0029] The device has redesigned the slide rail 7 so that the device has the function of dynamic adjustment of the workpiece. The support frame 2 is provided to provide rotational support for the roller 4. When the roller 4 rotates, it generates an axial thrust to the right on the workpiece, pushing the workpiece to the right. A discharge port 21 is opened on the right side of the support frame 2, so that the number of workpieces passing through the discharge port 21 can be throttled. The small size design of the discharge port 21 provides a probability that the workpiece enters the slide rail 7 in a normal posture. When a workpiece with an abnormal posture enters the slide rail 7, it will inevitably protrude upward from the upper surface of the slide rail 7. At this time, a guide plate 9 is provided to block the protruding workpiece and guide it so that the workpiece is guided to the slide rail 8. After the guidance and movement, the posture of the workpiece is quickly adjusted and returns to the slide rail 7. This design enables the device to have a synchronous deviation correction function during the feeding process, which greatly improves the reliability of the device.

[0030] The bottom of the fixing tube 18 is provided with a mounting groove 28, and the four sides of the inner wall of the mounting groove 28 are provided with fixing grooves 30. The mounting tube 19 is movably connected to the mounting groove 28, and the outer surface of the mounting tube 19 is provided with a clamping groove 29, and the inside of the clamping groove 29 is movably connected with a spring 31 and a clamping column 27;

[0031] The device is also designed with a damping strip 26 in conjunction with the slide rail 7. When the workpiece slides into the waiting slot 24 and the assembly slot 25 through the slide rail 7 and enters the position directly below the assembly part 20, the damping strip 26 protrudes from the inner wall of the waiting slot 24 and the assembly slot 25, so that the workpiece squeezes the damping strip 26 and generates friction resistance to offset the impact force of the workpiece. When the first group of workpieces are assembled, the workpiece to be processed is just offset from the fixed cylinder 18 due to the friction resistance of the damping strip 26, thereby avoiding the rigid jamming and collision of the assembly part 20 and the fixed cylinder 18 on the workpiece when tightening the assembly once, which helps to improve the safety of the device.

[0032] The fixing cylinder 18 is made of a permanent magnet block, the mounting groove 28 and the mounting cylinder 19 are both in a "cross" shape, and the two ends of the clamping groove 29 are elastically connected to the clamping column 27 and the inner wall of the clamping groove 29 respectively;

[0033] The device also designs the assembly part 20 and the fixed cylinder 18 to be separated, so that different types of workpieces can be adapted with the corresponding assembly part 20. A "cross"-shaped installation groove 28 is provided at the bottom of the fixed cylinder 18, which is used to magnetically clamp the installation cylinder 19, thereby facilitating replacement and disassembly. By providing a fixed groove 30 on the inner wall of the installation groove 28, the centrifugal force generated by the rotation of the fixed cylinder 18 and the installation cylinder 19 driven by the motor 2 17 drives the clamping column 27 to move toward one side of the fixed groove 30 and clamp it into the fixed groove 30, thereby firmly clamping the installation cylinder 19 and the fixed cylinder 18 together, thereby improving the stability of the device. When the motor 2 17 stops running, the clamping column 27 is reset under the pulling force of the spring 31, which is convenient for replacement and disassembly. This design greatly improves the working efficiency of the device.

[0034] The damping strip 26 is made of a rubber block, and the shape of the damping strip 26 is "U"-shaped. The damping strip 26 protrudes inwardly from the inner walls of the material waiting trough 24 and the assembly trough 25;

[0035] The damping strip 26 is responsible for contacting the workpiece and being compressed to generate friction resistance, thereby offsetting the impact force generated by the workpiece sliding down the inner wall of the slide rail 7, and preventing the two workpieces from entering the assembly area inside the assembly groove 25 at the same time.

[0036] The two ends of the spring 16 are elastically connected to the assembly plate 15 and the transmission assembly block 6, respectively. The two ends of the spring 14 are elastically connected to the moving plate 13 and the assembly plate 15, respectively. The bottom of the moving plate 13 can abut against the motor 17.

[0037] Spring 2 16 provides elastic support for assembly plate 15 and motor 2 17, resets motor 2 17 and assembly part 20, and spring 14 provides buffer between assembly plate 15 and hydraulic cylinder 12. When hydraulic cylinder 12 drives moving plate 13 downward, by compressing spring 14 and spring 2 16, assembly plate 15 and assembly part 20 apply flexible and continuously increasing pressure to the workpiece, which helps to prevent damage to the workpiece.

[0038] Among them, the inner walls of the slide rail 1 7 and the slide rail 2 8 are both designed as a "T"-shaped cavity, and the slide rail 2 8 is arranged on the front and rear sides of the inclined surface of the slide rail 1 7, and the upper and lower openings of the slide rail 2 8 are respectively connected to the guide port 22 and the return port 23;

[0039] The inner cavity of the slide rail 1 7 and the slide rail 2 8 has been redesigned to perfectly fit the cylindrical enlarged head design of the screw, thereby increasing the probability of loading the workpiece in a normal posture.

[0040] The cross-sectional shape of the guide plate 9 in top view is "V" shaped, and the guide plate 9 is fixedly connected to the top of the inclined surface of the slide rail 7;

[0041] The "V"-shaped design of the guide plate 9 can accurately intercept and guide the workpiece moving in an abnormal posture on the slide rail 1 7, introduce the workpiece into the slide rail 2 8, and automatically correct the workpiece by increasing the movement degree and changing the posture of the workpiece to restore the normal loading posture.

[0042] Among them, the pulling force of the spring three 31 on the clamping column 27 is smaller than the magnetic attraction force of the fixing cylinder 18 on the clamping column 27, and the friction force between the mounting cylinder 19 and the mounting cylinder 19 due to the magnetic attraction is larger than the gravity of the mounting cylinder 19;

[0043] The installation cylinder 19 is inserted into the inner wall of the installation groove 28 and fixed by the magnetic attraction of the fixing cylinder 18. In a stationary state, the clamping column 27 is pulled into the clamping groove 29 by the spring three 31, which is convenient for the replacement and disassembly of the assembly 20. The motor two 17 drives the installation cylinder 19 and the assembly 20 to rotate to generate centrifugal force, and drives the clamping column 27 to be inserted into the fixing groove 30, so that the installation cylinder 19 and the fixing cylinder 18 are connected more tightly.

[0044] Working principle:

[0045] When the device is working, firstly, the workpiece (screw) is placed into the drum 4 along the left opening of the drum 4, the motor 3 is started, and the drum 4 is driven to rotate through the transmission belt 5, and the workpiece is pushed to the right under the spiral rotation of the drum 4, so that the material enters the slide rail 7 along the discharge port 21;

[0046] Then, the workpieces are pushed by each other to get stuck in the inner wall of the slide rail 7 and slide to the right into the slope of the slide rail 7. The workpieces slide along the inner wall of the slide rail 7 to the material waiting groove 24 in a normal posture (with the big head on top and the threaded column part on the bottom), and then continue to move to the right and contact and squeeze the damping strip 26. The friction force generated by the deformation of the damping strip 26 slows down the speed, and the subsequent workpieces that move to the right generate impact force, which pushes the first workpiece that enters the material waiting groove 24 to continue to push to the right until the workpiece completely contacts the inner wall of the assembly groove 25.

[0047] The workpiece is in an abnormal posture (the big head is tilted and the threaded column part is on top). At this time, when the workpiece passes the first arc on the upper side of the slide rail 7, it will be blocked by the guide plate 9, so that it cannot slide down along the normal path, but will be guided by the inclined plates on both sides of the guide plate 9 to the slide rails 2 8 on both sides of the transport direction of the slide rail 7. The workpiece entering the slide rail 2 8 can automatically and quickly adjust its posture after rolling, and restore it to a normal posture, and then move downward along the inner wall of the slide rail 2 8. The workpiece after secondary state adjustment is located near the return port 23, at the intersection of the lower end outlet of the slide rail 2 8 and the slide rail 1 7, and then returns to the slide rail 1 7 under the impact of the next group of workpieces;

[0048] Finally, assembly begins, the transmission assembly block 6 is located on the clamp, and the device housing is fixed by the clamp and located below the transmission assembly block 6 (note: the clamp is a prior art and can be reasonably omitted here), the installation cylinder 19 is inserted upward into the installation groove 28, so that the installation cylinder 19 and the assembly 20 are fixed under the magnetic attraction of the fixed cylinder 18, the hydraulic cylinder 12 is started, and the movable plate 13 is driven to move downward, the spring 14 is compressed, the assembly plate 15 is driven downward, and the spring 2 16 is compressed. When the assembly 20 is inserted into the top of the workpiece, the motor 2 17 is started, and the fixed cylinder 18, the installation cylinder 19 and the assembly 20 are driven to rotate. At this time, the card column 27 in the card slot 29 moves outward under the action of centrifugal force, and is inserted into the fixed groove 30, thereby improving the connection tightness between the installation cylinder 19 and the fixed cylinder 18. The hydraulic cylinder 12 continues to drive the assembly 20 and the workpiece downward, successfully tightens, and completes the assembly.
