Description

Technical Field

[0001] The invention relates to the technical field of spring screw assembly equipment, in particular to a full-automatic spring screw assembly machine. Background Art

[0002] Screws are tools that use the physics and mathematical principles of the circular rotation of the inclined surface of an object and the friction force to gradually tighten objects and parts. The spring screw assembly machine is used to assemble springs, screws and other components into a complete product. This machine can improve production efficiency, reduce manual operation errors and labor intensity, and ensure product quality and consistency.

[0003] An existing spring screw assembly machine product has a carrier plate placed on a workbench with multiple holes. The spring is first placed in the hole, and then multiple screws are input onto the spring through a feeding device to assemble the spring and the screw. Since this product uses multiple holes to load the screws and springs, there are a large number of springs and screws after assembly, which need to be removed one by one. After all are removed, the springs need to be placed one by one during the next assembly. The assembly process is relatively cumbersome and the continuity is weak. Summary of the invention

[0004] The object of the present invention is to provide a fully automatic spring screw assembly machine to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is a fully automatic spring screw assembly machine, comprising a frame, wherein blanking assemblies are respectively installed on the tops of both ends of the frame, a carrier is connected between the two ends of the frame, and guide rails are respectively connected to the outer walls of both sides of the carrier;

[0007] A feeding assembly is installed on the two guide rails, and a driving assembly is installed at the bottom of the frame, and the driving assembly drives the feeding assembly;

[0008] The carrier is provided with a hole, the upper surface of the carrier is installed with two baffles, and the bottom port of the hole is installed with a flap assembly;

[0009] A circular hole is arranged on the outer wall of the carrier, the circular hole extends to the inside of the hole, and an arc plate is installed on the outer wall of the circular hole;

[0010] A material pushing assembly is installed on the outer wall of the carrier, and the material pushing assembly drives the flap assembly;

[0011] A feeding plate is connected to the outer wall of the frame, one end of the feeding plate extends to the outside of the frame, and the other end of the feeding plate extends to the bottom of the hole;

[0012] The purpose of the above arrangement is to respectively feed the screws and springs through the two feeding assemblies, the springs are fed to the upper surface of the carrier, and the screws are fed to the arc plate, the feeding assembly is driven by the driving assembly, and the feeding assembly moves on the two guide rails, and during the movement, the springs are clamped and transported, and the springs are released when they are transported to the top of the hole, and the springs fall onto the flap assembly;

[0013] The feeding assembly continues to move to the end of the guide rail and then returns. During the return movement, the feeding assembly drives the pushing assembly to move, and the pushing assembly drives the screw on the arc plate to move toward the inside of the hole. At the same time, the pushing assembly drives the flap assembly to rotate, and slowly opens the bottom port of the hole. The spring tilts as the flap assembly rotates, and the threaded end of the screw tilts and slides into the middle of the spring, thereby assembling the spring on the outer wall of the screw. The flap assembly continues to rotate, and when the opened port is larger than the caliber of the spring, the screw and spring slide into the feeding plate to complete the assembly.

[0014] Further, the driving assembly includes a second motor and a screw, the second motor is mounted on the bottom outer wall of the frame, two ends of the screw are rotatably connected to the two ends of the bottom of the frame respectively, and the output end of the second motor is connected to one end of the screw;

[0015] The purpose of the above arrangement is that the output end of the second motor drives the screw to rotate, thereby driving the feeding assembly.

[0016] Furthermore, the unloading assembly comprises a frame body, the frame body is installed at one end of the frame, and a feed port is provided on the top of the frame body;

[0017] Two gears are rotatably connected to the outer wall of the frame, the two gears are meshed with each other, the rotating shafts of the two gears respectively penetrate the frame, and a plurality of blades are respectively installed on the outer walls of the rotating shafts of the two gears;

[0018] A support frame is connected to the outer wall of the frame, a first motor is installed on the top of the support frame, an output of the first motor is connected to one of the gears, and an inclined plate is installed on the bottom inner wall of the frame;

[0019] The purpose of the above arrangement is that two material cutting assemblies are provided, and the two material cutting assemblies are used to cut springs and screws respectively. The springs and screws are fed through the feed port respectively, and one of the gears is driven to rotate clockwise through the output end of the first motor, and the two gears are meshed with each other, and the other gear rotates counterclockwise, and the blade is driven to rotate through the rotating shaft of the gear. The screws and springs are placed on the two blades, and when the two gears rotate, the two blades move away from each other;

[0020] When the gap between the two blades is not enough for the screw or spring to fall, the two blades behind will move closer to each other to support the next screw or spring.

[0021] When the front screw or spring falls, the rear screw or spring is on the two blades. The above steps are to intermittently discharge the screws or springs, thereby preventing excessive discharge from causing material blockage.

[0022] Furthermore, the feeding assembly includes a special-shaped frame, the top ends of which are respectively slidably connected to the upper surfaces of the two guide rails, and the top ends of the special-shaped frame are respectively provided with moving grooves;

[0023] The inner walls of the two guide rails are slidably connected with sliding frames, the sliding frames are slidably connected to the inner wall of the moving groove, and one end of the two sliding frames is respectively installed with a clamping block, and the two clamping blocks are arc-shaped;

[0024] The screw rod passes through the bottom of the special-shaped frame and is threadedly connected;

[0025] The purpose of the above arrangement is that when the screw rotates, the screw is threadedly connected to the bottom of the special-shaped frame, thereby driving the special-shaped frame. When the special-shaped frame moves, it drives the sliding frame to move. The two sliding frames move according to the trajectories of the two guide rails, so that the two sliding frames are respectively close to and away from each other on the moving groove, so that the two clamping blocks first approach each other, drive the spring to move, and when they move to the top of the hole, the two clamping blocks move away from each other along the trajectory of the guide rail, and the spring enters the hole.

[0026] Further, the pusher assembly includes a pusher rack and a sliding slot plate, the two sliding slot plates are respectively mounted on the outer wall of the carrier, the two ends of the pusher rack are respectively slidably connected to the inner wall of the sliding slot plate, and the inner walls of the two sliding slot plates are respectively mounted with return springs;

[0027] The purpose of the above arrangement is that the pusher rack slides on the sliding slot plate to push the screws, and the reset spring is used to reset the pusher rack.

[0028] Furthermore, the outer walls on both sides of the carrier are respectively connected with blocking rods, the outer walls on both sides of the pusher rack are respectively rotatably connected with rotating racks, the top of the rotating rack is rotatably connected with rollers, the outer walls of the rollers are in contact with the lower surface of the blocking rods, and the two ends of the pusher rack are respectively provided with vertical grooves;

[0029] The purpose of the above arrangement is that the special-shaped frame moves on the guide rail, the special-shaped frame pushes the rotating frame, and the rotating frame and the roller rotate clockwise, so that the special-shaped frame can move to the end of the guide rail, and the rotating frame and the roller are reset under the influence of their own gravity;

[0030] Then the special-shaped frame returns on the guide rail, the special-shaped frame pushes the rotating frame, and the blocking rod blocks the counterclockwise rotation of the rotating frame and the roller, so that the rotating frame cannot rotate counterclockwise. Subsequently, because the special-shaped frame continues to move, the roller is forced to rotate and roll on the lower surface of the blocking rod, so that the rotating frame can drive the pushing frame to move, and the pushing frame squeezes the reset spring.

[0031] Furthermore, the flap assembly includes an inclined slot plate, a sliding rod, a sliding block and a flap, and the two inclined slot plates are respectively mounted on the outer wall of the carrier, and the two inclined slot plates are inclinedly arranged on the outer wall of the carrier;

[0032] One end of the flap is rotatably connected to the bottom of the carrier, and a slide groove is provided inside the flap;

[0033] The two ends of the sliding rod pass through the vertical slot and the inclined slot plate respectively and are slidably connected;

[0034] A sliding block is rotatably connected to the outer wall of the sliding rod, and the sliding block is slidably connected to the inner wall of the sliding groove;

[0035] The purpose of the above arrangement is that when the push rack moves, the screw on the arc plate is pushed into the hole. At this time, the vertical slot drives the sliding rod to move, and the slider and the sliding rod follow the trajectory of the inclined slot plate to tilt and move. The slider rotates on the sliding rod and slides on the slide slot at the same time. Therefore, when the slider slides on the slide slot, it controls the flap to rotate, allowing the flap to slowly open the bottom port of the hole. During this process, the spring gradually tilts on the flap, and the threaded end of the screw tilts and slides into the middle of the spring, thereby assembling the spring on the outer wall of the screw. The flap continues to rotate. When the opened port is larger than the caliber of the spring, the screw and the spring slide into the feeding plate to complete the assembly.

[0036] At this time, the roller moves to the outside of the stop rod, and the roller and the rotating frame can rotate counterclockwise. When the special-shaped frame continues to be moved, the roller and the rotating frame rotate counterclockwise. After the special-shaped frame passes through the rotating frame, the rotating frame and the roller are reset due to their own gravity, and then the reset spring resets the pusher frame, and the next process is carried out, and the screws and springs are assembled in a reciprocating cycle.

[0037] The present invention has the following beneficial effects:

[0038] (1) The present invention is provided with a driving assembly, a feeding assembly, a carrier, a guide rail and a pushing assembly. The screws and springs are respectively fed through two feeding assemblies. The springs are fed to the upper surface of the carrier, and the screws are fed to the arc plate. The feeding assembly is driven by the driving assembly, and the feeding assembly moves on the two guide rails. During the movement, the spring is clamped and transported. When the spring is transported to the top of the hole, the spring is released, and the spring falls onto the flap assembly.

[0039] The feeding assembly continues to move to the end of the guide rail and then returns. During the return movement, the feeding assembly drives the pushing assembly to move, and the pushing assembly drives the screw on the arc plate to move toward the inside of the hole. At the same time, the pushing assembly drives the flap assembly to rotate, and slowly opens the bottom port of the hole. The spring tilts as the flap assembly rotates, and the threaded end of the screw tilts and slides into the middle of the spring, thereby assembling the spring on the outer wall of the screw. The flap assembly continues to rotate, and when the opened port is larger than the caliber of the spring, the screw and spring slide into the feeding plate to complete the assembly. This process triggers the pushing assembly and the flap assembly by repeatedly moving the feeding assembly, and assembles the screw and spring. After the assembly is completed, the material can be discharged and the next assembly can be carried out. This cycle can maintain good continuity.

[0040] (2) The present invention sets a blanking assembly, drives one of the gears to rotate clockwise through the output end of the first motor, the two gears mesh with each other, the other gear rotates counterclockwise, and drives the blade to rotate through the rotating shaft of the gear. In combination with the figure, screws and springs are placed on the two blades. When the two gears rotate, the two blades move away from each other;

[0041] When the gap between the two blades is not enough for the screw or spring to fall, the two blades behind will move closer to each other to support the next screw or spring.

[0042] When the front screw or spring falls, the rear screw or spring is on the two blades. The above steps are to intermittently discharge the screws or springs, thereby preventing excessive discharge from causing material blockage.

[0043] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0069] As an implementation method, Figure 2 and Fig.10 As shown, further:

[0070] The unloading assembly 2 includes a frame 201, which is installed at one end of the frame 1, and a feed port 205 is provided on the top of the frame 201;

[0071] Two gears 203 are rotatably connected to the outer wall of the frame 201. The two gears 203 mesh with each other. The shafts of the two gears 203 penetrate the frame 201 respectively. A plurality of blades 204 are respectively installed on the outer walls of the shafts of the two gears 203.

The two gears 203 are meshed with each other, and the other gear 203 rotates counterclockwise, and the blade 204 is driven to rotate through the rotating shaft of the gear 203. Fig.10 , the screws and springs are placed on the two blades 204, and when the two gears 203 rotate, the two blades 204 move away from each other;

[0074] When the gap between the two blades 204 is not enough to allow the screw or spring to fall, the next two blades 204 move closer to each other to support the next screw or spring;

[0075] When the front screw or spring falls, the rear screw or spring is on the two blades 204. The above steps are to intermittently discharge the screws or springs, thereby preventing excessive discharge from causing material blockage.

[0076] As an implementation method, Figure 3 and Figure 4 As shown, further:

[0077] The feeding assembly 4 includes a special-shaped frame 401, the top ends of which are slidably connected to the upper surfaces of the two guide rails 6, and the top ends of the special-shaped frame 401 are respectively provided with moving grooves 4010;

[0078] The inner walls of the two guide rails 6 are slidably connected with sliding frames 402, and the sliding frames 402 are slidably connected to the inner walls of the moving grooves 4010. One end of the two sliding frames 402 is respectively installed with a clamping block 403, and the two clamping blocks 403 are arc-shaped;

[0079] The screw rod 302 penetrates the bottom of the special-shaped frame 401 and is threadedly connected;

[0080] In this embodiment, the purpose of the above-mentioned setting is that when the screw rod 302 rotates, the screw rod 302 is threadedly connected with the bottom of the special-shaped frame 401, thereby driving the special-shaped frame 401.

The two sliding frames 402 move according to the trajectories of the two guide rails 6, so that the two sliding frames 402 are respectively close to and away from each other on the moving groove 4010, so that the two clamping blocks 403 first approach each other, drive the spring to move, and when moving to the top of the hole 501, the two clamping blocks 403 move away from each other along the trajectory of the guide rail 6, and the spring enters the hole 501.

[0081] As an implementation method, Figure 5 As shown, further:

[0082] The pusher assembly 7 includes a pusher frame 701 and a sliding slot plate 704. The two sliding slot plates 704 are respectively installed on the outer wall of the carrier 5. The two ends of the pusher frame 701 are respectively slidably connected to the inner wall of the sliding slot plate 704. The inner walls of the two sliding slot plates 704 are respectively installed with return springs 705.

[0083] In this embodiment, the purpose of the above arrangement is that the pusher rack 701 slides on the sliding slot plate 704 to push the screws, and the reset spring 705 is used to reset the pusher rack 701.

[0084] As an implementation method, Figure 4 - Figure 6 As shown, further:

[0085] The outer walls of both sides of the carrier 5 are connected to the blocking rods 503 respectively, the outer walls of both sides of the pusher frame 701 are rotatably connected to the rotating frames 702 respectively, the top of the rotating frame 702 is rotatably connected to the roller 703, the outer wall of the roller 703 is in contact with the lower surface of the blocking rods 503, and the two ends of the pusher frame 701 are respectively provided with vertical grooves 7010;

[0086] In this embodiment, the purpose of the above arrangement is that the special-shaped frame 401 moves on the guide rail 6, the special-shaped frame 401 pushes the rotating frame 702, and the rotating frame 702 and the roller 703 rotate clockwise, so that the special-shaped frame 401 moves to the end of the guide rail 6, and the rotating frame 702 and the roller 703 are reset under the influence of their own gravity;

[0087] Then the special-shaped frame 401 returns on the guide rail 6, and the special-shaped frame 401 pushes the rotating frame 702, and the blocking rod 503 blocks the rotating frame 702 and the roller 703 from rotating counterclockwise, and the rotating frame 702 cannot rotate counterclockwise. Subsequently, because the special-shaped frame 401 continues to move, the roller 703 is forced to rotate and roll on the lower surface of the blocking rod 503, so that the rotating frame 702 can drive the pushing frame 701 to move, and the pushing frame 701 squeezes the reset spring 705.

[0088] As an implementation method, Figure 5 - Fig. 9 As shown, further:

[0089] The flap assembly includes a chute plate 9, a sliding rod 10, a slider 11 and a flap 12. The two chute plates 9 are respectively mounted on the outer wall of the carrier 5. The two chute plates 9 are tilted on the outer wall of the carrier 5.

[0090] One end of the flap 12 is rotatably connected to the bottom of the carrier 5, and a slide groove 1201 is provided inside the flap 12;

[0091] The two ends of the sliding rod 10 pass through the vertical slot 7010 and the inclined slot plate 9 respectively, and are slidably connected;

[0092] A slider 11 is rotatably connected to the outer wall of the sliding rod 10, and the slider 11 is slidably connected to the inner wall of the sliding groove 1201;

[0093] In this embodiment, the purpose of the above arrangement is that when the pusher 701 moves, the screw on the arc plate 504 is pushed into the hole 501. At this time, the vertical groove 7010 drives the sliding rod 10 to move, and the slider 11 and the sliding rod 10 follow the trajectory of the inclined groove plate 9 to tilt and move. The slider 11 rotates on the sliding rod 10 and slides on the slide groove 1201 at the same time. Therefore, when the slider 11 slides on the slide groove 1201, it controls the flap 12 to rotate, allowing the flap 12 to slowly open the bottom port of the hole 501. During this process, the spring gradually tilts on the flap 12, and the threaded end of the screw tilts and slides into the middle of the spring, thereby assembling the spring on the outer wall of the screw. The flap 12 continues to rotate. When the opened port is larger than the caliber of the spring, the screw and the spring slide into the feeding plate 8 to complete the assembly.

[0094] At this time, the roller 703 moves to the outside of the blocking rod 503, and the roller 703 and the rotating frame 702 can rotate counterclockwise. When the special-shaped frame 401 continues to be moved, the roller 703 and the rotating frame 702 rotate counterclockwise. After the special-shaped frame 401 passes through the rotating frame 702, the rotating frame 702 and the roller 703 are reset due to their own gravity, and then the reset spring 705 resets the pushing frame 701, and the next process is carried out, and the screws and springs are assembled repeatedly.

[0095] Working principle: There are two feeding assemblies 2, and the two feeding assemblies 2 feed the spring and the screw respectively. The spring and the screw are fed through the feeding port 205 respectively, and one of the gears 203 is driven to rotate clockwise through the output end of the first motor 207. The two gears 203 are meshed with each other, and the other gear 203 rotates counterclockwise, and the blade 204 is driven to rotate through the rotating shaft of the gear 203. Fig.10 , the screws and springs are placed on the two blades 204, and when the two gears 203 rotate, the two blades 204 move away from each other;

[0096] When the gap between the two blades 204 is not enough to allow the screw or spring to fall, the next two blades 204 move closer to each other to support the next screw or spring;

[0097] When the front screw or spring falls, the rear screw or spring is on the two blades 204. After the front screw and spring are assembled, the rear screw and spring are unloaded. The above steps are intermittent unloading of screws or springs, thereby preventing material blockage caused by excessive unloading, and allowing the screws and springs to be assembled in an orderly manner;

[0098] The output end of the second motor 301 drives the screw rod 302 to rotate, thereby driving the feeding assembly 4. When the screw rod 302 rotates, the screw rod 302 is threadedly connected to the bottom of the special-shaped frame 401, thereby driving the special-shaped frame 401. When the special-shaped frame 401 moves, it drives the sliding frame 402 to move. The two sliding frames 402 move according to the tracks of the two guide rails 6, so that the two sliding frames 402 are respectively close to and away from each other on the moving groove 4010, so that the two clamping blocks 403 first approach each other, drive the spring to move, and when moving to the top of the hole 501, the two clamping blocks 403 move away from each other along the track of the guide rail 6, and the spring enters the hole 501;

[0099] The pusher frame 701 slides on the sliding slot plate 704 to push the screws. The reset spring 705 is used to reset the pusher frame 701. The special-shaped frame 401 moves on the guide rail 6. The special-shaped frame 401 pushes the rotating frame 702. The rotating frame 702 and the roller 703 rotate clockwise to facilitate the special-shaped frame 401 to move to the end of the guide rail 6. The rotating frame 702 and the roller 703 are reset under the influence of their own gravity.

[0100] Then the special-shaped frame 401 returns on the guide rail 6, and the special-shaped frame 401 pushes the rotating frame 702, and the blocking rod 503 blocks the rotating frame 702 and the roller 703 from rotating counterclockwise, so that the rotating frame 702 cannot rotate counterclockwise. Subsequently, because the special-shaped frame 401 continues to move, the roller 703 is forced to rotate and roll on the lower surface of the blocking rod 503, so that the rotating frame 702 can drive the pusher frame 701 to move, and the pusher frame 701 squeezes the reset spring 705;

[0101] When the pusher 701 moves, the screw on the arc plate 504 is pushed into the hole 501. At this time, the vertical groove 7010 drives the sliding rod 10 to move, and the slider 11 and the sliding rod 10 follow the trajectory of the inclined groove plate 9 to move obliquely. The slider 11 rotates on the sliding rod 10 and slides on the slide groove 1201 at the same time. Therefore, when the slider 11 slides on the slide groove 1201, it controls the flap 12 to rotate, allowing the flap 12 to slowly open the bottom port of the hole 501. During this process, the spring gradually tilts on the flap 12, and the threaded end of the screw tilts and slides into the middle of the spring, so that the spring is assembled on the outer wall of the screw. The flap 12 continues to rotate. When the opened port is larger than the caliber of the spring, the screw and the spring slide into the feeding plate 8 to complete the assembly.

[0102] At this time, the roller 703 moves to the outside of the blocking rod 503, and the roller 703 and the rotating frame 702 can rotate counterclockwise. When the special-shaped frame 401 continues to be moved, the roller 703 and the rotating frame 702 rotate counterclockwise. After the special-shaped frame 401 passes through the rotating frame 702, the rotating frame 702 and the roller 703 are reset due to their own gravity, and then the reset spring 705 resets the pushing frame 701, and the next process is carried out, and the screws and springs are assembled repeatedly.
