Description

Technical Field

[0001] The present invention relates to the technical field of automation equipment, in particular to an automatic feeding device for spring parts. Background Art

[0002] Springs are used in the assembly and production of many products and equipment. Automatically feeding spring parts is a crucial step in achieving automated production. In the prior art, automatic feeding of spring parts typically involves the use of a linear vibrator and a vibrating feed tray. For example, in the patent application CN 214721966 U, a device for automatically feeding and separating springs is described. The vibrating feed tray uses vibration to align scattered spring components and feed them into a feed channel. Gravity and vibration push the springs in the feed channel toward the feed opening. When a spring reaches the feed opening, it is detected by a sensor, then clamped by a pneumatic clamp mechanism. The pneumatic clamp mechanism then moves to feed the spring to the next process. When the pneumatic clamp mechanism is used to clamp the spring at the feed opening, vibration is paused, the springs in the feed channel stop moving, and a barrier is placed against the feed opening. In particular, for torsion springs with long straight torsion arms at each end, vibrating with a vibrating feed tray can easily cause multiple springs to become stuck together due to the straight torsion arms. Therefore, the existing automatic spring feeding device still needs to be researched and innovated to further improve its operating efficiency. Summary of the Invention

[0003] In order to achieve the above purpose, this scheme proposes an automatic feeding device for spring parts, which is mainly suitable for close-fitting springs and torsion springs with straight torsion arms extending a certain length at the upper and lower ends.

[0004] The technical solution employed in the present invention is an automatic spring component feeding device comprising a mounting platform, a rotary screening and feeding mechanism mounted on the mounting platform, and a material retrieving and feeding mechanism. The mounting platform is tilted, and the rotary screening and feeding mechanism and the material retrieving and feeding mechanism are also tilted on the mounting platform. The rotary screening and feeding mechanism comprises multiple evenly spaced column support legs. A material storage barrel is mounted at the top of the column support legs. The barrel wall and barrel bottom are connected in a separate manner. A motor is connected to the center of the barrel bottom to drive the barrel bottom in a circular rotation. The barrel bottom has multiple evenly spaced through-holes near the bottom edge. Cylinders are mounted within the through-holes and move up and down within the through-holes. A mechanism is provided at the bottom of the barrel bottom to connect the cylinders and drive them up and down within the through-holes. A notch is provided at the bottom edge of the barrel wall at the highest point of the tilt angle. The notch connects to a spring feed channel, where a material retrieving and feeding mechanism is located. The spring feed channel receives spring components one by one from the outlet of the spring feed channel and supplies them to the next process.

[0005] The lower end of the column support foot is vertically connected to the platform surface of the installation platform bracket, the upper end of the column support foot is connected to a circular ring piece, and the lower end of the barrel wall is provided with a vertically outward extending annular connecting portion, which is fixedly connected to the circular ring piece.

[0006] The spring-loaded material channel comprises a channel base, front and rear levers, which are arranged parallel to the channel base, forming a discharge channel between the front and rear levers. A circular ring member is provided with a groove opening corresponding to the notch in the barrel wall. The channel base plate has an arc-shaped opening at the front end and a U-shaped opening at the rear end. The arc-shaped opening is inserted into the groove opening, and the channel base plate is flush with the inner bottom surface of the barrel bottom. The channel base plate is fixedly connected to the circular ring member.

[0007] The ends of the front and rear levers that extend into the notches in the barrel wall form the input end of the spring delivery channel. The front and rear levers at the input end are provided with beveled cutouts to form a "trumpet"-shaped input port. The ends of the front and rear levers that extend away from the storage barrel form the output end of the spring delivery channel. An elastic stop is provided on the rear lever at the output end. A fiber optic sensor is installed on the front lever opposite the elastic stop to detect whether a spring component has reached the output end of the spring delivery channel.

[0008] Furthermore, the front and rear gear rods are provided with connecting holes that are connected to the material channel bottom plate with screws. The connecting holes are set to be elliptical. The distance between the front and rear gear rods can be adjusted through the elliptical connecting holes to adjust the width of the spring output material channel. The width of the spring output material channel is adjusted to adapt to spring parts with a caliber within a certain range so that they can be universally used.

[0009] The material retrieving and feeding mechanism comprises a forward and backward propulsion cylinder mounted on the platform surface of the mounting platform bracket. The front end of the forward and backward propulsion cylinder is connected to a vertically mounted vertical propulsion cylinder. A mounting bracket is provided outside the vertical propulsion cylinder, and a pair of parallel plate connecting seats are mounted on the mounting bracket. A movable block is positioned between the two parallel plates. Through holes are provided in the side walls of the two parallel plates and the movable block, and a shaft is positioned within the through holes. The movable block has an inclined surface on its front side, and a plug-in post is mounted on the inclined surface. Due to the tilted arrangement of the entire device, the inclined surface of the movable block is horizontal after the plug-in post inserts and removes the spring component.

[0010] Furthermore, the bottom side of the double parallel plate connecting seat is provided with a slot that passes through the inner side of a parallel plate. A connecting rod is inserted into the slot from the lower end. A guide hole is provided on the movable block. A pin is provided on the upper end of the connecting rod, and the pin is inserted into the guide hole. The lower end of the connecting rod is connected to a single-axis push cylinder, which pushes the connecting rod up and down. When the connecting rod is pushed upward, the movable block is centered on the shaft, and the pin pushes the guide hole to rotate the movable block. The plug-in column on the movable block will align with the bottom of the U-shaped opening. Then, the mounting frame is pushed upward as a whole by pushing the cylinder up and down, so that the plug-in column can plug into the spring part at the output end of the spring output channel. The spring part is then conveyed forward by pushing the cylinder forward and backward. At the same time, the single-axis push cylinder pulls down the straight rod, so that the inclined surface of the movable block plug-in column with the spring part plugged in is rotated to a horizontal state, so as to realize the feeding of spring parts for the next process.

[0011] The up and down driving mechanism of the cylinder is that an "L"-shaped connecting rod is provided on the side of each through hole at the bottom of the barrel bottom, and the upper end of the "L"-shaped connecting rod is fixedly connected to the barrel bottom, and the rod body at the lower end of the "L"-shaped connecting rod is provided with an insertion hole facing the bottom of the barrel bottom. The insertion hole is inserted into a straight rod from the bottom, and a compression spring is sleeved on the upper end of the straight rod. A connecting block is provided on the upper end of the straight rod. The cylinder is connected to the connecting block. Through the elastic force of the compression spring, the connecting block abuts against the bottom of the barrel bottom. At this time, the cylinder is protruding from the inner bottom surface of the barrel bottom.

[0012] Furthermore, a cam bearing is disposed inwardly at the lower end of the straight rod, perpendicular to the straight rod. A cam guide mechanism, including the cam bearing, is disposed on the platform surface of the mounting platform bracket, correspondingly below the highest point of the tilted storage barrel. The cam guide mechanism comprises an arc-shaped seat, the outer sidewall of which is provided with a guide groove channel. The guide groove channel is oriented with high ends and low in the middle. The motor drives the barrel bottom to rotate, which in turn drives the cam of the cam bearing through the guide groove channel. When the cam passes through the middle of the guide groove channel, the cam bearing pulls the straight rod downward, thereby moving the connecting block and cylindrical body at the upper end of the straight rod downward. The cylindrical body then moves downward within the through hole in the barrel bottom. After the cam passes through the guide groove channel, the elastic force of the compression spring causes the cylindrical body to rebound and protrude from the inner bottom surface of the barrel bottom.

[0013] The motor drives the bottom of the storage barrel to rotate, thereby stirring the spring parts inside the barrel. Because the storage barrel is installed at an angle, there are multiple cylinders at the bottom of the barrel that protrude from the bottom surface of the barrel. The cylinders have spring parts hanging on them. When the cylinders with spring parts hang on them pass the storage barrel to the highest point, due to the storage barrel's tilted installation, the spring parts not hanging on the cylinders fall to the tilted bottom of the storage barrel due to the action of gravity. Because the connecting block connecting the cylinders and the cam bearing at the lower end of the straight rod pass through the guide groove channel, the guide groove channel pulls the straight rod downward, causing the cylinder in this position to move downward. At this time, the spring part is in the spring output channel. It reaches this position through the next spring part, and continuously pushes the previous spring part to the output port of the spring output channel for acquisition by the feeding mechanism.

[0014] The beneficial effects of the present invention are as follows: compared with the prior art method of using a vibrating plate to achieve material distribution and feeding, the present solution is designed to use a motor to drive the inclined barrel bottom to rotate rapidly, stirring the spring parts in the barrel to hang on the cylinder, and the cylinder rotates to the highest point. The guide groove channel of the arc-shaped seat body provided below the highest point pulls the connecting block, straight rod, and cam bearing connected to the cylinder. The cam bearing passes through the guide groove channel to pull down the cylinder so that the spring parts hanging on the cylinder enter the spring output channel, and then the cylinder is reset by compressing the spring to carry out the next spring hanging. This solution realizes a higher efficiency in the automatic feeding of spring parts, and is suitable for the automatic feeding of ordinary springs with coiled upper and lower ends, and torsion springs with straight torsion arms of a certain length at the upper and lower ends.

[0030] Reference Figure 6 、 Figure 7 The spring output channel 400 includes a channel bottom plate 41, a front side gear rod 42, and a rear side gear rod 43. The front side gear rod 42 and the rear side gear rod 43 are arranged parallel to the channel bottom plate 41, and a discharge channel is formed between the front side gear rod 42 and the rear side gear rod 43; the circular ring member 4 is provided with a groove opening 401 at the notch 51 corresponding to the barrel wall 5, and the front end of the channel bottom plate 41 is provided with an arc opening, and the rear end of the channel bottom plate 41 is provided with a U-shaped opening 411. The arc opening is inserted into the groove opening 401, and the channel bottom plate 41 is flush with the inner bottom surface of the barrel bottom 6. The channel bottom plate 41 is fixedly connected to the circular ring member 4.

The "trumpet" shaped input port 412 is more convenient for spring parts to be brought into the spring output channel 400.

[0032] Preferably, the front and rear gear rods 42 and 43 are located at the ends away from the storage barrel, forming the output end of the spring output channel. An elastic stop block 45 is provided on the rear gear rod 43 at the output end.

[0034] Reference Figure 1 、 Figure 2 , Figures 8 and 9The material retrieving and feeding mechanism 300 includes a forward and backward propulsion cylinder 31 mounted on the platform surface 1 of the mounting platform bracket 100. The front end of the forward and backward propulsion cylinder 31 is connected to a vertically mounted vertical propulsion cylinder 32. A mounting bracket 33 is provided outside the vertical propulsion cylinder 32, and a double parallel plate connecting seat 34 is provided on the mounting bracket 33. A movable block 35 is provided between the two parallel plates of the double parallel plate connecting seat 34. The side walls of the double parallel plates and the movable block 35 are provided with a through hole extending therethrough, and a shaft 36 is disposed within the through hole. The front side of the movable block 35 is provided with an inclined surface 352, on which a plug-in post 37 is mounted. The bottom side of the dual parallel plate connecting base 34 is provided with a notch 341 that penetrates the inner side of one of the parallel plates. A connecting rod 38 is inserted from the lower end of the notch 341. The movable block 35 is provided with a guide hole 351. The upper end of the connecting rod 38 is provided with a pin 381 that is inserted into the guide hole 351. The lower end of the connecting rod 38 is connected to a single-axis propulsion cylinder 39 that pushes the connecting rod 38 up and down. When the connecting rod 38 is pushed upward, the movable block 35 is centered on the shaft 36, and the pin 381 pushes the guide hole 351, causing the movable block 35 to rotate. The plug-in post 37 on the movable block 35 will align with the bottom of the U-shaped opening 411. By pushing the cylinder 32 up and down, the plug-in column 37 is plugged into the spring part at the output end of the spring output channel 400, and then the spring part is conveyed by pushing the cylinder 31 forward and backward to realize the feeding of the spring part for the next process.

[0035] Reference Figure 3 、 Figure 4 The mechanism for driving the cylinder up and down is an L-shaped connecting rod 9, located at the side of each through-hole at the bottom of the barrel bottom 6. The upper end of the L-shaped connecting rod 9 is fixedly connected to the barrel bottom 6. The lower end of the L-shaped connecting rod 9 has a through-hole facing the bottom of the barrel bottom 6. A straight rod 10 is inserted into the through-hole from the bottom. A compression spring 11 is sleeved on the upper end of the straight rod 10. A connecting block 12 is also installed at the upper end of the straight rod 10, connecting the cylinder 8 to the connecting block 12. The elastic force of the compression spring 11 forces the connecting block 12 to abut the bottom of the barrel bottom 6, causing the cylinder 8 to protrude from the inner bottom surface of the barrel bottom 6. A cam bearing 13 perpendicular to the straight rod 10 is set inward at the lower end of the straight rod 10, and a cam guide mechanism of the cam bearing 13 is set on the platform surface 1 of the mounting platform bracket 100 at a position below the highest point of the inclination of the storage barrel. The cam guide mechanism is an arc-shaped seat body 14, and the outer side wall of the arc-shaped wall of the arc-shaped seat body 14 is provided with a guide groove channel 141, and the guide groove channel 141 is high at both ends and low in the middle.

[0036] The motor 7 drives the barrel bottom 6 to rotate, which in turn drives the cam of the cam bearing 13 to pass through the guide groove channel 141. When the cam passes the middle of the guide groove channel 141, the cam bearing 13 pulls the straight rod 10 downward, thereby causing the connecting block 12 at the upper end of the straight rod 10 and the cylindrical body 8 to move downward. The cylindrical body 8 then moves downward within the through hole of the barrel bottom 6. After the cam passes through the guide groove channel 141, the elastic force of the compression spring 11 causes the cylindrical body 8 to rebound and protrude from the inner bottom surface of the barrel bottom 6.

[0037] Better, refer to Figure 5 The upper and lower channel walls of the guide groove channel 141 at the channel opening at one end where the cam of the cam bearing 13 enters are set into inclined surfaces, forming a "trumpet" shaped entry channel opening 142.

[0038] Better, refer to Figure 4 The storage barrel is provided with a cover body 15, and a cover body locking block 151 is provided on the bottom edge of the cover body 15. An inner convex edge 52 is provided on the inner wall of the upper end opening of the barrel wall 5. The inner convex edge 52 forms a non-closed loop. The non-closed loop is the entrance for the cover body locking block. The cover body locking block 151 and the bottom of the cover body 15 form a bayonet. When the cover body 15 is rotated, the inner convex edge 52 is stuck in the bayonet to fix the cover body 15 to the barrel wall 5.

[0039] Preferably, the motor 7 is a stepper motor, which is fixed with a fixing bracket, a coupling, etc. The installation and fixing of the stepper motor is an existing technology and will not be described in detail.

[0040] The automatic spring component feeding device of the present invention operates as follows: a motor 7 drives the bottom 6 of the storage barrel to rotate, thereby stirring the spring components within the barrel. Because the barrel is tilted, multiple cylindrical bodies 8 protruding from the inner bottom surface of the barrel bottom 6 have spring components attached to them. When a cylindrical body 8 with spring components passes the barrel to its highest point, due to the tilted barrel, other spring components not attached to the cylindrical body 8 fall to the bottom of the barrel due to gravity. Because the connecting block 12 connected to the cylindrical body 8 and the cam bearing 13 at the lower end of the straight rod 10 pass through the guide channel 14, the guide channel 14's high ends and low center structure pulls the straight rod 10 downward, causing the cylindrical body 8 in this position to move downward. At this point, the spring component is in the spring output channel 400, and the next spring component reaches this position, continuously pushing the previous spring component to the output port of the spring output channel 400 for collection by the feeding mechanism 300.

[0041] It should be noted that the material picking and feeding mechanism 300 disclosed in the present invention adopts a cylinder-type push to realize forward and backward pushing and upward and downward pushing to realize the plug-in column 37 to obtain the spring parts. This is a mechanical structure proposed by the present invention with a simple structure, stable operation and low cost. As a replacement for the material picking and feeding mechanism 300, it can be replaced by an existing manipulator device that meets the requirements of positioning and grasping objects.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and modifications fall within the scope of the invention as claimed.
