Description

Technical Field

[0001] This utility model relates to the technical field of picture frame back panel production equipment, specifically, a spring feeding device for automatically feeding springs during the production of picture frame back panels. Background Technology

[0002] Existing photo frame back panels are all fixed inside the frame by a swing spring clip. The structure of the spring clip can be found in the appendix. Figure 7 The spring includes a hinge portion 26 and a pressing portion 27. The hinge portion 26 has a hinge hole for hinged to the back panel of the photo frame. The pressing portion 27 and the hinge portion 26 are at an angle, such that the pressing portion 27 is inclined at one end of the hinge portion 26. The pressing portion 27 includes a pressing section 28, which has a clearance hole 29. One end of the pressing section 28 is connected to the hinge portion 26 through a concave connecting piece 30, and the other end is provided with a hook section 31, which is concave relative to the pressing section 28.

[0003] When in use, press the pressing part 27 and rotate it into the preset retaining groove of the frame edge. After releasing, the inclined connecting piece 30 rebounds and resets, so that the hook section 31 is firmly locked into the preset retaining groove of the frame edge, thereby fixing the back panel securely in the frame.

[0004] However, when installing the spring clips in the existing photo frame back panel, it is necessary to manually hold the photo frame back panel with one hand and grasp the pressing part 27 with the other hand, place the hinge part 26 flat on the photo frame back panel, and then stamp and rivet. The whole process requires manual handling, which is labor-intensive and inefficient. In addition, since the spring clip itself is a thin product, the spring clips are prone to stacking in the existing automatic spring clip feeding conveyor, resulting in poor positioning ability and equipment failure. Utility Model Content

[0005] In order to overcome the defects of the existing technology, this utility model provides a spring feeding device to solve the problems in the existing technology.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a spring sheet feeding device, including a spring sheet vibrating plate, the output end of which is connected to a spring sheet positioning and conveying component, the spring sheet positioning and conveying component including a spring sheet suspension platform, one end of which is connected to the spring sheet vibrating plate, and the other end is provided with an adsorption discharge groove, so that the spring sheet vibrating plate conveys the spring sheet into the spring sheet suspension platform and the spring sheet is arranged and suspended in the spring sheet suspension platform. An adsorption limiting member is provided on the side of the adsorption discharge groove away from the spring sheet suspension platform, so that the spring sheet falls into the adsorption discharge groove and is adsorbed and attached to the surface of the adsorption limiting member.

[0007] In the above-mentioned spring feeding device, a vibrator is installed at the lower end of the spring suspension table, and the lower end of the vibrator is installed on the base.

[0008] In the above-mentioned spring feeding device, a supporting inclined surface is provided on the spring suspension platform, and a supporting plane is provided at the lower end of the supporting inclined surface. A first limiting strip and a second limiting strip are provided parallel to each other along the length direction of the supporting inclined surface. The first limiting strip and the second limiting strip are both suspended on the supporting inclined surface by connecting rods, so that the first limiting strip and the second limiting strip form a spring conveying area with the supporting inclined surface.

[0009] In the aforementioned spring sheet feeding device, a first through hole and a second through hole are respectively provided between the first limiting strip and the second limiting strip. The first through hole and the second through hole both penetrate the supporting plane. The first through hole and the second through hole are arranged side by side and are located at one end close to the adsorption discharge trough. A first cylinder and a second cylinder are respectively installed on one side of the lower end of the spring sheet suspension table through a cylinder seat. The output shaft of the first cylinder is connected to a first limiting pin, and the output shaft of the second cylinder is connected to a second limiting pin. The first limiting pin passes through the first through hole, and the second limiting pin passes through the second through hole.

[0010] In the above-mentioned spring feeding device, an air jet pipe is provided above the first through hole and the second through hole. The air jet pipe is installed on the support plane through an air pipe seat. The output end of the air jet pipe is located between the first limiting strip and the second limiting strip, and the output end of the air jet pipe faces the adsorption discharge trough, so that the spring is blown toward and falls into the adsorption discharge trough.

[0011] In the above-mentioned shrapnel feeding device, the output end of the jet pipe is a flat opening.

[0012] In the above-mentioned spring feeding device, the adsorption limiting member includes a side plate installed on one side of the base. The side plate near the adsorption discharge trough is a side plane, which is connected to the side of the adsorption discharge trough. A magnetic strip groove is provided on the side of the side plate away from the adsorption discharge trough. A movable magnet is installed in the magnetic strip groove. An infrared sensor is provided on one side of the magnetic strip groove, and the detection end of the infrared sensor is located on the surface of the side plane.

[0013] In the above-mentioned spring feeding device, the bottom of the magnetic strip groove is not through the side plane surface, and the distance between the bottom of the magnetic strip groove and the side plane surface is 2-3mm.

[0014] In the above-mentioned spring feeding device, a magnet base is connected to one side of the magnet, and a strip hole is opened on the magnet base so that the magnet base is installed on the side plate by bolts passing through the strip hole.

[0015] The beneficial effects of this utility model are that the spring sheet is vibrated and conveyed by the spring sheet vibrating plate, so that the spring sheet enters the spring sheet suspension table for positioning and arrangement. After the spring sheet enters the adsorption discharge trough, the spring sheet is adsorbed and attached to the surface of the adsorption limiting part, thereby completing the positioning and conveying, waiting for the robot arm in the next process to pick it up at the same position, so that manual feeding is not required. Moreover, during the conveying process, the spring sheet is positioned in the spring sheet suspension table by positioning and suspension, which effectively prevents the spring sheet from overlapping, and the overall positioning capability is high.

[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] Combination Figures 1 to 7 The illustrated spring sheet feeding device includes a spring sheet vibratory feeder 1. A spring sheet positioning and conveying assembly 2 is connected to the output end of the vibratory feeder 1. The spring sheet positioning and conveying assembly 2 includes a spring sheet suspension platform 5. One end of the suspension platform 5 is connected to the vibratory feeder 1, and the other end is provided with an adsorption discharge trough 13. This allows the vibratory feeder 1 to convey spring sheets into the suspension platform 5, arranging and suspending the spring sheets within it. An adsorption limiting member 4 is provided on the side of the adsorption discharge trough 13 away from the suspension platform 5, causing the spring sheets to fall into the adsorption discharge trough 13 and adhere to the surface of the adsorption limiting member 4. On the surface, that is, the side of the spring sheet is adsorbed and attached to the surface of the adsorption limiting member 4; in this embodiment, the spring sheet is vibrated and conveyed by the spring sheet vibrating plate 1, so that the spring sheet enters the spring sheet suspension table 5 for positioning and arrangement. After the spring sheet enters the adsorption discharge trough 13, the spring sheet is adsorbed and attached to the surface of the adsorption limiting member 4, thereby completing the positioning and conveying, waiting for the robot arm of the next process to pick it up at the same position, so that manual feeding is not required. Moreover, during the conveying process, the spring sheet is positioned in the spring sheet suspension table 5 by positioning and suspension, which effectively prevents the spring sheet from overlapping, and the overall positioning capability is high.

[0026] It is worth noting that a vibrator 14 is installed at the lower end of the spring plate suspension table 5 in this embodiment, and the lower end of the vibrator 14 is installed on the base 3; so that the spring plate can move further in the spring plate suspension table 5 by vibration. In some embodiments, the spring plate suspension table 5 can be tilted at a certain angle towards the adsorption discharge trough 13, so that the spring plate moves towards the adsorption discharge trough 13 under vibration.

[0027] In this embodiment, a support slope 6 is provided on the spring piece suspension table 5, and a support plane 7 is provided at the lower end of the support slope 6. A first limiting strip 8 and a second limiting strip 9 are provided parallel to each other along the length direction of the support slope 6. The first limiting strip 8 and the second limiting strip 9 are both suspended on the support slope 6 by a connecting rod 10, so that the first limiting strip 8 and the second limiting strip 9 form a spring piece conveying area with the support slope 6. Under the action of the first limiting strip 8 and the second limiting strip 9, the support slope 6 and the support plane 7 can support the spring piece, and the concave hook segment 31 hooks the lower end of the first limiting strip 8. The second limiting strip 8 is located in the concave connecting piece 30, so that the entire spring piece is positioned in the spring piece conveying area and arranged in the spring piece conveying area to prevent the spring pieces from stacking.

[0028] Specifically, a first through hole and a second through hole are respectively provided between the first limiting strip 8 and the second limiting strip 9. Both the first through hole and the second through hole penetrate the supporting plane 7. The first through hole and the second through hole are arranged side by side and are located at one end near the adsorption discharge trough 13. The lower end of the spring plate suspension table 5 is equipped with a first cylinder 17 and a second cylinder 18 respectively through a cylinder seat. The output shaft of the first cylinder 17 is connected to a first limiting pin 15, and the output shaft of the second cylinder 18 is connected to a second limiting pin 16. The first limiting pin 15 passes through the first through hole, and the second limiting pin 16 passes through the second through hole. Before the spring plate enters the adsorption discharge trough 13, the first limiting pin 15 is in a retracted state, while the second limiting pin 16 is in an extended state. The second limiting pin 16 passes into another spring plate adjacent to the spring plate near the adsorption discharge trough 13, so that the second limiting pin 16 locks the spring plate and prevents the two spring plates from entering the adsorption discharge trough 13 and stacking.

[0029] In order to quickly separate two adjacent spring pieces near the adsorption discharge trough 13 and allow them to quickly enter the adsorption discharge trough 13, an air jet pipe 12 is provided above the first and second through holes. The air jet pipe 12 is mounted on the support plane 7 via an air pipe seat 11. The output end of the air jet pipe 12 is located between the first limiting strip 8 and the second limiting strip 9, and the output end of the air jet pipe 12 faces the adsorption discharge trough 13, causing the spring pieces to be blown towards and fall into the adsorption discharge trough 13. The output end of the air jet pipe 12 is a flat opening. In some embodiments, a relevant sensor, such as an infrared sensor, is provided on the spring piece suspension platform 5 to detect the position of the spring pieces. When the first limiting pin 15 is in the retracted state, the jet pipe 12 blows air, causing the spring closest to the adsorption discharge trough 13 to move rapidly within the spring conveying area and slide into the adsorption discharge trough 13. At this time, the first limiting pin 15 extends, while the second limiting pin 16 retracts, and the vibrator 14 vibrates, causing the spring in the spring conveying area to move forward until the spring that is close to the adsorption discharge trough 13 again stops moving under the limit of the first limiting pin 15. The vibrator 14 stops vibrating, the first limiting pin 15 retracts, and the second limiting pin 16 extends and inserts to lock the spring, preventing two springs from entering the adsorption discharge trough 13 at the same time during the next air blowing.

[0030] The adsorption limiting component 4 in this embodiment includes a side plate 19 installed on one side of the base 3. The side of the side plate 19 near the adsorption discharge trough 13 is a side plane 20, which is connected to the side of the adsorption discharge trough 13. A magnetic strip groove 21 is provided on the side of the side plate 19 away from the adsorption discharge trough 13. A movable magnet 22 is installed in the magnetic strip groove 21. An infrared sensor 25 is provided on one side of the magnetic strip groove 21, and the detection end of the infrared sensor 25 is located on the surface of the side plane 20. After the spring piece enters the adsorption discharge trough 13, the magnet 22 can quickly attach and lock the side of the spring piece to the surface of the side plane 20 to prevent the spring piece from shifting, so that the spring piece is in the same position before each transfer and riveting.

[0031] It is worth noting that the bottom of the magnetic strip groove 21 is not through the surface of the side plane 20, and the distance between the bottom of the magnetic strip groove 21 and the surface of the side plane 20 is 2-3mm. Since the spring is a small product, only a weak magnetic force is needed for the magnet 22 to attract the spring; a strong magnet is not required to prevent the spring from failing during the transfer in the next process.

[0032] In this embodiment, a magnet base 23 is connected to one side of the magnet 22. The magnet base 23 has a strip hole 24, which is bolted through the strip hole 24 and installed on the side plate 19. Both the magnet strip groove 21 and the strip hole 24 are inclined devices. By loosening the bolt, the magnet base 23 can be moved under the action of the strip hole 24, thereby adjusting the position of the magnet 22 in the magnet strip groove 21, so as to adjust the height and position of the spring sheet in the adsorption discharge trough 13.

[0033] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
