Description

Technical Field

[0001] This utility model relates to the field of automatic spring feeding technology, and in particular to a feeding device compatible with springs of different heights. Background Technology

[0002] Springs are common components in the machinery industry, produced in large quantities, with diverse shapes, functions, and varieties, and have a wide range of applications. In the field of automated assembly, a continuous and stable supply of springs is required to achieve automatic feeding, thus eliminating the need for manual assistance.

[0003] The spring feeder uses a vibratory feeder to feed the springs vertically through a pipe. However, a single spring feeder can only handle one type of spring and cannot adapt to springs of different heights. Therefore, it cannot meet the requirements of adapting to springs of different heights and thus be compatible with the production and assembly of multiple springs. It is necessary to improve some of the structures in the existing spring feeder. Now, in order to facilitate the feeding and assembly of springs, a feeding device that can be compatible with springs of different heights is needed to achieve versatility and enable the assembly and production of multiple products. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies that cannot be compatible with springs of different heights, and to provide a feeding device that is compatible with springs of different heights. This allows for the assembly and production of multiple products without changing the mechanism.

[0005] To achieve the above objectives, this utility model provides a feeding device compatible with springs of different heights, including a frame. A vertical drive assembly is mounted on the upper part of the frame, and a misalignment assembly is mounted on the lower part. A moving plate is mounted on the vertical drive assembly, which drives the moving plate to move vertically. A spring input assembly for vertically inputting springs and an output pipe for vertically outputting springs are flexibly connected to the moving plate. The output pipe is mounted below the spring input assembly. A side clamping assembly is mounted below the moving plate, used to clamp the springs output from the output pipe from the side. The misalignment assembly is connected to the end of the output pipe, used to laterally misalign the springs entering the misalignment assembly, and is then blown by a blowing assembly mounted on the misalignment assembly.

[0006] Preferably, the side clamping assembly includes a clamping cylinder mounted on the lower part of the moving plate and clamping claws mounted on both sides of the clamping cylinder. The clamping claws are located at the end of the output pipe, and the clamping cylinder drives the clamping claws to clamp the spring at the end of the output pipe from the side.

[0007] Preferably, the output tube has an inclined guide surface inside and an insertion slope at the end, the inclined guide surface guides the spring through the output tube; the insertion slope has insertion grooves on both sides, the end of the clamping claw is inserted into the insertion groove to clamp the spring inside the output tube from the side, and the end of the clamping claw has an arc-shaped groove adapted to the side of the spring.

[0008] Preferably, the misalignment assembly includes a mounting plate installed on the lower part of the frame, a U-shaped groove plate installed on the mounting plate, and a misalignment drive cylinder installed on one side of the U-shaped groove plate. The U-shaped groove plate has a placement groove, and a misalignment plate is installed at the end of the misalignment drive cylinder. The misalignment plate is inserted into the placement groove, and the misalignment plate has a placement hole for placing a spring. A second sensor for detecting the spring inside the placement hole is installed on the outside of the U-shaped groove plate. The placement groove has a through hole, and the misalignment drive cylinder drives the spring on the misalignment plate to move misaligned within the placement groove, moving the spring to the upper part of the through hole and into the through hole.

[0009] Preferably, the blowing assembly includes a cover plate mounted on the upper part of the U-shaped groove plate, which vertically limits the misalignment plate; a pneumatic connector is mounted on the cover plate, which is located above and aligned with the through hole; a blowing pipe connected to the through hole is mounted on the lower part of the U-shaped groove plate, which conveys the spring; a vent hole connected to the pneumatic connector and the through hole is provided on the misalignment plate; the gas blown out by the pneumatic connector enters the blowing pipe through the vent hole and the through hole in sequence, and conveys the spring into the interior of the blowing pipe; and a receiving groove is provided on the cover plate for accommodating the clamping claw and the output pipe.

[0010] Preferably, the movable plate is equipped with a spring feed plate, which is installed between the spring input assembly and the output tube; the spring passes through the spring feed plate and enters the interior of the output tube, the output tube passes through the movable plate and its end is located at the lower part of the movable plate, and a first sensor for detecting the position of the spring inside the output tube is installed on the upper outer side of the output tube.

[0011] Preferably, the spring input assembly includes a vibratory plate mounted on the frame and at least one connecting pipe mounted at the end of the vibratory plate, wherein the end of the connecting pipe away from the vibratory plate is connected to the spring feed plate; the vibratory plate arranges several springs installed inside the vibratory plate into at least one column and outputs them through the connecting pipe to the spring feed plate.

[0012] Preferably, the vertical drive assembly includes a drive motor mounted on the upper part of the frame, a transmission screw mounted at the end of the drive motor, and a screw slider sleeved on the transmission screw; a movable plate is mounted on the screw slider; the drive motor drives the output tube on the movable plate to move closer to or away from the misalignment assembly, thereby controlling the vertical height of the spring output.

[0013] Preferably, the frame is also equipped with a vertical guide rail and a vertical slider sleeved on the vertical guide rail. The vertical slider is equipped with a lead screw slider, which moves vertically along the vertical guide rail via the vertical slider.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. Operation process of this utility model: First, the vertical drive component drives the output tube to approach the misalignment component, connecting their ends. Second, the spring input component vertically inputs the spring, which is output through the end of the output tube. Third, the side clamping component releases the spring output from the end of the output tube, and the springs sequentially move vertically downwards into the misalignment component. The side clamping component clamps the upper spring that has entered the misalignment component, ensuring that only one spring enters the misalignment component. The vertical drive component drives the output tube, the side clamping component, and the upper spring to move vertically upwards, away from the misalignment component, removing the excess spring ends that have entered the misalignment component, allowing them to move vertically upwards to facilitate the subsequent lateral misalignment movement of the misalignment component. Finally, the misalignment component laterally misaligns the springs that have entered the misalignment component, and the blowing component mounted on the misalignment component blows them, thus completing the conveying process.

[0016] 2. The present invention ensures that only one spring enters the misalignment component when the side clamping assembly is released. When one spring enters the misalignment component, due to the height and the stacking of the two springs, the upper spring cannot enter the misalignment component and is clamped by the side clamping assembly and driven away from the misalignment component by the vertical drive assembly; thus achieving that only one spring enters the misalignment component each time.

[0017] 3. The vertical height of the spring compatible with this utility model is also limited. The vertical height of the spring cannot be higher than the height of the placement hole, otherwise staggered switching cannot be performed. The vertical height of the spring can be lower than or equal to the height of the placement hole, so that it can be placed stably and staggered switching can be performed. However, the vertical height of the spring cannot be lower than or equal to half the height of the placement hole, otherwise two springs may be placed in the placement hole at one time, which is not conducive to single conveying. This utility model controls the vertical height of the end of the output tube, so that it can be compatible with springs of different heights for feeding, and can assemble and produce multiple products without changing the mechanism.

[0028] The technical solution of this embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiment is one embodiment of the present invention, and not all embodiments thereof. Based on this embodiment of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please refer to Figures 1 to 7 This utility model provides a feeding device compatible with springs of different heights.

[0030] like Figure 1 As shown, the feeding device includes a frame 1. A vertical drive assembly 8 is mounted on the upper part of the frame 1, and a misalignment assembly 9 is mounted on the lower part. A moving plate 4 is mounted on the vertical drive assembly 8. The vertical drive assembly 8 drives the moving plate 4 to move vertically back and forth, continuously adjusting the vertical height of the moving plate 4. This allows the spring 2 to move closer to or further away from the misalignment assembly 9, enabling subsequent individual springs 2 to be conveyed sequentially. To facilitate the vertical movement of the moving plate 4, a spring input assembly 3 is flexibly connected to the moving plate 4. The spring input assembly 3 is used to vertically input the springs 2, and the input springs 2 are arranged vertically in a stacked manner. The moving plate 4 is also equipped with an output pipe 6 for vertically outputting the springs 2. The output pipe 6 is mounted on the lower part of the spring input assembly 3.

[0031] like Figure 1 As shown, the lower part of the movable plate 4 is equipped with a side clamping assembly 7. The side clamping assembly 7 is used to clamp the spring 2 output from the output pipe 6 from the side and block the end of the output pipe 6 to control the orderly output of the output pipe 6 and prevent the spring 2 from being output randomly. Under the drive of the vertical drive assembly 8, the end of the output pipe 6 moves closer to the misalignment assembly 9 and connects with each other, so that the spring 2 at the end of the output pipe 6 enters the misalignment assembly 9. This allows the misalignment assembly 9 to laterally misalign the spring 2 that has entered the misalignment assembly 9. After the spring 2 is misaligned, it enters the blowing assembly 10 installed on the misalignment assembly 9 and is blown by the blowing assembly 10.

[0032] Driven by the vertical drive assembly 8, the output tube 6 moves away from the misalignment assembly 9, thus separating from each other. This also vertically drives and transfers the spring 2 on the upper part of the misalignment assembly 9, without affecting the subsequent misalignment movement, ensuring that there is only one spring 2 in the misalignment assembly 9.

[0033] like Figure 1 As shown, in this embodiment, there are two motion stations. In other embodiments, with adaptive changes, there can be one station or three stations.

[0034] like Figure 2 and Figure 3 As shown, the side clamping assembly 7 includes a clamping cylinder 71 installed on the lower part of the moving plate 4 and clamping claws 72 installed on both sides of the clamping cylinder 71. The clamping claws 72 are located at the end of the output pipe 6. The clamping cylinder 71 drives the clamping claws 72 to clamp the spring 2 at the end of the output pipe 6 from the side.

[0035] The spring 2 at the end of the output tube 6 is the same spring 2 that could not enter the misalignment component 9 last time, and it is also the spring 2 that will enter the misalignment component 9 next time.

[0036] like Figure 4 As shown, the output tube 6 has an inclined guide surface 61 inside and an insertion inclined surface 62 at the end. The inclined guide surface 61 guides the spring 2 through the output tube 6. The insertion inclined surface 62 is inserted into the misalignment component 9 to facilitate subsequent docking with the placement hole 96, thereby facilitating the vertical entry of the spring 2 into the placement hole 96.

[0037] like Figure 4 As shown, the insertion inclined surface 62 is provided with insertion grooves 63 on both sides. The end of the clamping claw 72 is inserted into the insertion groove 63 to clamp the spring 2 inside the output tube 6 from the side. Furthermore, in order to better clamp the spring 2 and increase the clamping contact area, the end of the clamping claw 72 is provided with an arc-shaped groove 73 that is adapted to the side of the spring 2.

[0038] Furthermore, if you want to increase friction even further, you can add friction stripes on the arc-shaped groove 73 to improve friction.

[0039] like Figure 5 and Figure 6 As shown, the misalignment component 9 includes a mounting plate 91 installed on the lower part of the frame 1, a U-shaped groove plate 92 installed on the mounting plate 91, and a misalignment drive cylinder 93 installed on one side of the U-shaped groove plate 92; specifically, the U-shaped groove plate 92 is installed on the upper part of the mounting plate 91, the misalignment drive cylinder 93 is installed on an L-shaped fixing frame, and the L-shaped fixing frame is installed below the U-shaped groove plate 92, as shown. Figure 6 As shown, the U-shaped groove plate 92 is provided with a placement groove 94, and the end of the misalignment drive cylinder 93 is equipped with a misalignment plate 95. The misalignment plate 95 is inserted into the placement groove 94, and the misalignment drive cylinder 93 drives the misalignment plate 95 to move laterally back and forth inside the placement groove 94, thereby misaligning the spring 2 on the misalignment plate 95.

[0040] like Figure 6As shown, the misalignment plate 95 is provided with a placement hole 96 for placing the spring 2, and a second sensor 98 for detecting the spring 2 inside the placement hole 96 is installed on the outside of the U-shaped groove plate 92; the end of the output tube 6 is connected to the placement hole 96, and the spring 2 output by the output tube 6 enters the placement hole 96 and is sensed by the second sensor 98, thereby starting the subsequent misalignment movement.

[0041] The placement groove 94 is provided with a through hole 97. The misalignment driving cylinder 93 drives the spring 2 on the misalignment plate 95 to move misaligned inside the placement groove 94, moving the spring 2 to the upper part of the through hole 97 and into the through hole 97, and then into the blowing pipe 13.

[0042] like Figure 5 and Figure 6 As shown, the blowing assembly 10 includes a cover plate 11 installed on the upper part of the U-shaped groove plate 92. The cover plate 11 vertically limits the misaligned plate 95 to ensure that the misaligned plate 95 moves stably in the horizontal reciprocating motion inside the placement groove 94.

[0043] like Figure 5 and Figure 6 As shown, a pneumatic connector 12 is installed on the cover plate 11. The pneumatic connector 12 is located above the through hole 97 and aligned with the through hole 97. A blow pipe 13 connected to the through hole 97 is installed at the lower part of the U-shaped groove plate 92. The blow pipe 13 conveys the spring 2. A vent hole 14 connected to the pneumatic connector 12 and the through hole 97 is provided on the misaligned plate 95. The gas blown out by the pneumatic connector 12 enters the blow pipe 13 through the vent hole 14 and the through hole 97 in sequence, and conveys the spring 2 into the blow pipe 13, thereby realizing pneumatic blowing.

[0044] Furthermore, in order to accommodate the clamping claw 72 and the output tube 6, and to facilitate the docking of the output tube 6 with the placement hole 96, thereby stably placing the spring 2 inside the placement hole 96; the cover plate 11 is provided with a receiving groove 15 for accommodating the clamping claw 72 and the output tube 6, and the clamping claw 72 and the output tube 6 can pass through the receiving groove 15 to reach above the placement hole 96, so that the placement hole 96 and the output tube 6 are connected.

[0045] like Figure 2 As shown, a spring feed plate 5 is installed on the moving plate 4, and the spring feed plate 5 is installed between the connecting pipe 32 and the output pipe 6; the spring 2 passes through the spring feed plate 5 and enters the interior of the output pipe 6, and the output pipe 6 passes through the moving plate 4, with its end located at the lower part of the moving plate 4.

[0046] In order to detect the number of springs 2 inside the output tube 6 and to ensure continuous feeding, a first sensor 51 for detecting the position of the springs 2 inside the output tube 6 is installed on the upper outer side of the output tube 6.

[0047] When the first sensor 51 detects that there is no spring 2 inside the output tube 6, it activates the spring input assembly 3, causing the connecting tube 32 to continuously supply spring 2 into the output tube 6; when the first sensor 51 detects that there is spring 2 inside the output tube 6, it stops the spring input assembly 3, and the output tube 6 consumes the spring 2 inside.

[0048] like Figure 1 As shown, the spring input assembly 3 includes a vibratory plate 31 mounted on the frame 1 and two connecting pipes 32 mounted at the end of the vibratory plate 31. The end of the connecting pipe 32 away from the vibratory plate 31 is connected to the spring feed plate 5. The vibratory plate 31 arranges several springs 2 installed inside the vibratory plate 31 into two rows and outputs them through the connecting pipes 32 to the spring feed plate 5. The springs 2 pass through the spring feed plate 5 and enter the output pipe 6, and the output is controlled by the clamping claw 72.

[0049] like Figure 7 As shown, the vertical drive assembly 8 includes a drive motor 81 mounted on the upper part of the frame 1, a transmission screw 82 mounted on the end of the drive motor 81, and a screw slider 83 sleeved on the transmission screw 82; a moving plate 4 is mounted on the screw slider 83; the drive motor 81 drives the output pipe 6 on the moving plate 4 to move closer to or away from the misalignment assembly 9, thereby controlling the vertical height output by the spring 2.

[0050] The transmission lead screw 82 and lead screw slider 83 cooperate with each other to convert the rotational motion of the drive motor 81 into the vertical reciprocating motion of the moving plate 4.

[0051] To make the vertical movement of the moving plate 4, the output pipe 6 and the side clamping assembly 7 more stable, the frame 1 is also equipped with a vertical guide rail 84 and a vertical slider 85 sleeved on the vertical guide rail 84. A lead screw slider 83 is installed on the vertical slider 85, and the lead screw slider 83 moves vertically along the vertical guide rail 84 through the vertical slider 85.

[0052] Adding a vertical guide rail 84 and a vertical slider 85 can increase the driving accuracy of the vertical drive assembly 8, which is important for the moving plate 4 with micro-motion, enabling slow and precise vertical feed.

[0053] The operation steps of the feeding device are as follows:

[0054] Step S1: The vibratory feeder 31 arranges several springs 2 installed inside the vibratory feeder 31 into two rows, and outputs them through the connecting pipe 32 to the spring feed plate 5, and then through the spring feed plate 5 into the output pipe 6.

[0055] Step S2: The drive motor 81 drives the output tube 6 on the moving plate 4 to approach the misalignment component 9 through the cooperation of the transmission screw 82 and the screw slider 83, and passes through the receiving groove 15 to reach the top of the placement hole 96, so that the placement hole 96 is connected to the end of the output tube 6, which facilitates the subsequent entry of the spring 2 at the end of the output tube 6 into the placement hole 96.

[0056] Step S3: The clamping cylinder 71 drives the clamping claw 72 to release the spring 2 at the end of the output tube 6. Under the action of gravity, the spring 2 moves vertically downward and enters the placement hole 96. Only one spring 2 or one half spring 2 can be placed in the placement hole 96. The clamping cylinder 71 drives the clamping claw 72 to clamp the spring 2 at the top of the placement hole 96 to ensure that only one spring 2 enters the placement hole 96.

[0057] Step S4: The second sensor 98 senses the spring 2 inside the placement hole 96; the drive motor 81 drives the moving plate 4, the output tube 6, the clamping claw 72, and the spring 2 between the clamping claw 72 away from the placement hole 96. The clamping claw 72 removes the excess spring 2 that has entered the placement hole 96 and moves vertically away from the placement hole 96, which facilitates the lateral misalignment movement of the subsequent misalignment component 9.

[0058] Step S5: The misalignment drive cylinder 93 drives the misalignment plate 95 to move laterally and reciprocally inside the placement groove 94, misaligning the spring 2 on the misalignment plate 95; so that the placement hole 96 is aligned with the through hole 97 on the placement groove 94, and the spring 2 enters the through hole 97 under the action of gravity, and then enters the blowing pipe 13.

[0059] Step S6: The misalignment drive cylinder 93 drives the misalignment plate 95 to reset. The vent 14 of the misalignment plate 95 is connected to the pneumatic connector 12 and the through hole 97. The gas blown out by the pneumatic connector 12 enters the blowing pipe 13 through the vent 14 and the through hole 97 in sequence, and transports the spring 2 inside the through hole 97 into the blowing pipe 13, thereby realizing pneumatic blowing.

[0060] Furthermore, the height of the placement hole 96 ensures that only one spring 2 can enter the placement hole 96. When one spring 2 enters the placement hole 96, due to the height and the stacking of the two springs 2, the upper spring 2 cannot enter the placement hole 96 and is thus clamped by the clamping claw 72. The clamping claw 72 and the upper spring 2 are driven away from the misalignment component 9 and the placement hole 96 by the drive motor 81, thereby realizing that only one spring 2 enters the misalignment component 9 at a time, so as to perform subsequent misalignment and pneumatic blowing.

[0061] Furthermore, the vertical height of the spring 2 compatible with this utility model is also limited. The vertical height of the spring 2 cannot be higher than the height of the placement hole 96, otherwise staggered switching cannot be performed. The vertical height of the spring 2 can be lower than or equal to the height of the placement hole 96, so that it can be placed stably and staggered switching can be performed. However, the vertical height of the spring 2 cannot be lower than or equal to half the height of the placement hole 96, otherwise two springs 2 may be placed in the placement hole 96 at one time, which is not conducive to single conveying. At the same time, the spring 2 must also have sufficient height to allow the clamping claw 72 to clamp the side of the spring 2.

[0062] This invention controls the vertical height of the output tube 6 end, thereby enabling the compatibility of springs of different heights for feeding, allowing for the assembly and production of multiple products without changing the mechanism.

[0063] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
