Description

Technical Field

[0001] This utility model belongs to the field of automation equipment technology, specifically referring to an automatic orientation device for Dutch needles and a badge machine. Background Technology

[0002] A Dutch pin is an accessory used for badges, usually made of metal. Its core structure includes a torsion spring, a pin body and a slot on both sides of the torsion spring. The slender pin body is used to insert into the hole on the bottom cover of the badge and lock with the slot to fit tightly with the bottom cover of the badge.

[0003] In the current badge assembly process, the Dutch pin is first fixed to the badge's lower cover, and then stamped using specialized badge assembly equipment. Referring to a fully automated badge assembly device disclosed in Chinese Invention Application 2019107679285, the badge lower cover is mostly conveyed via a vibratory feeder. During this conveying process, the orientation of the Dutch pin is random, resulting in a misalignment between the Dutch pin and the badge design in the finished badge. Consequently, when the user wears the badge, the design appears tilted, severely affecting the product's usability. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic orientation adjustment device and badge machine that can automatically adjust the orientation of the Dutch needle.

[0005] The purpose of this utility model is achieved as follows:

[0006] An automatic orientation device for a Dutch needle includes a vibratory feeder with a feeding channel connected to an orientation channel. The lower cover is conveyed by the vibratory feeder through the feeding channel and the orientation channel in sequence.

[0007] The directional channel is provided with a directional hole, and a check rod is provided in the directional hole. The diameter of the directional hole is smaller than the diameter of the lower cover, but larger than the length of the Dutch pin in the lower cover.

[0008] The anti-return rod is used to abut against the Dutch pin that falls into the directional hole when the lower cover is conveyed into the directional hole, thereby restricting the conveying of the lower cover;

[0009] The directional hole is used to support the lower cover so that it rotates under the drive of the vibratory plate when the check valve abuts against the Dutch needle; when the lower cover rotates until the torsion spring end of the Dutch needle is opposite to the check valve, the check valve abuts against the torsion spring end of the Dutch needle and slides along the torsion spring end to release the lower cover.

[0010] Furthermore, a pressure rod is rotatably provided on the directional channel, with one end of the pressure rod pressing against the directional hole.

[0011] Furthermore, the directional channel has a directional baffle, a rotating shaft is provided on the directional baffle, and the pressure rod is rotatably mounted on the rotating shaft.

[0012] Furthermore, the directional channel is also provided with a guide groove connected to the directional hole, the width of which is adapted to the width of the Dutch needle to accommodate the Dutch needle.

[0013] Furthermore, the directional channel includes a directional base plate, and the directional hole is formed on the directional base plate.

[0014] Furthermore, a stop rod fixing frame is provided under the adjusting base plate, and the stop rod fixing frame fixes the anti-return stop rod, which is inclined and its end is located in the adjusting hole.

[0015] A badge machine, comprising:

[0016] frame;

[0017] A processing base is mounted on the machine frame, and a punching head is installed on the processing base;

[0018] A robotic arm for transporting badge accessories and stickers to the processing station; and

[0019] The aforementioned automatic steering device.

[0020] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0021] This patent restricts the movement of the lower cover by setting a check valve, and allows movement only when the lower cover is oriented correctly. At the same time, the adjustment hole structure provides sufficient space for the rotation of the lower cover and the installation of the check valve. The check valve and the adjustment hole cooperate to realize the automatic adjustment of the Dutch needle in the lower cover. Attached Figure Description

[0029] The present invention will be further described below with reference to specific embodiments:

[0030] An automatic orientation device for Dutch needles, used in a badge machine, such as... Figure 1 As shown, the badge machine described in this patent includes a frame 5, a processing base 6, and a handling robot 8. The frame 5 has a mounting panel 51, on which the processing base 6, the handling robot 8, and the automatic adjustment device are mounted. The badge in this patent application consists of three parts: two lower covers 9 and a sticker installed between the two lower covers 9. The handling robot 8 sequentially places the lower covers 9 and the sticker onto the processing base 6, where the badge is stamped by the stamping head 7 on the processing base 6.

[0031] The automatic orientation device includes a vibratory feeder with a feeding channel 11 connected to an orientation channel 2. The lower cover 9 is conveyed by the vibratory feeder 1 through the feeding channel 11 and the orientation channel 2 in sequence. Since the badge in this patent includes an upper cover and a lower cover 9, the badge machine in this patent has two vibratory feeders 1, which are used to convey the upper cover and the lower cover 9 respectively. A loading channel 91 connected to the vibratory feeder is provided outside the vibratory feeder 1. The end of the loading channel 91 is located on one side of the handling robot 8. The upper cover and the lower cover 9 are continuously fed to the end of the loading channel 91 by the vibratory feeder 1, and then the handling robot 8 transports them to the processing seat 6.

[0032] The vibratory feeder 1 used for conveying the lower cover is provided with the aforementioned adjusting channel 2, the adjusting channel 2 having an adjusting hole 21, and a check valve 22 disposed within the adjusting hole 21. The diameter of the adjusting hole 21 is smaller than the diameter of the lower cover 9, but larger than the length of the Dutch needle in the lower cover 9. (Combined) Figure 2 , 3 As shown, the feeding channel 11 is spiral-shaped and formed in the vibrating plate 1. The lower cover 9 moves sequentially along the feeding channel 11 by the continuous vibration of the vibrating plate 1. The directional channel is located at the end of the feeding channel 11. The directional channel in this patent is straight and integrally formed with the feeding channel.

[0033] The directional channel 2 includes a directional base plate 24, with directional baffles 25 on both sides of the directional base plate 24, forming a directional channel 2 between the two directional baffles 25. The directional hole 21 is formed on the directional base plate 24, and the directional hole 21 is generally circular; for example... Figure 4 , 5 As shown, the bottom plate 24 is provided with a stop rod fixing frame 28. The stop rod fixing frame 28 is fixed to the bottom plate 24 by fasteners. The anti-reverse stop rod 22 is long and strip-shaped. Its front end can be fixed to the stop rod fixing frame 28 by welding or fasteners. The anti-reverse stop rod 22 is inclined as a whole, so that the other end of the anti-reverse stop rod 22 is inserted into the anti-reverse hole 21 from below and is higher than the bottom plate 24.

[0034] In this patent, the lower cover 9 is conveyed by a vibratory feeder 1. During the conveying process, the lower cover 9 first moves along the spiral feeding channel 11 and then enters the directional channel 2. When the lower cover 9 moves in the directional channel 2, its orientation will continuously change due to the vibration of the vibratory feeder 1. When the lower cover 9 is driven into the directional hole 21, since the diameter of the directional hole 21 is smaller than the diameter of the lower cover 9 but larger than the length of the Dutch needle in the lower cover 9, the Dutch needle on the lower cover 9 will fall into the directional hole 21 due to its gravity, and the edge of the lower cover 9 will abut against the outer edge of the directional hole 21 to support the lower cover 9. When the Dutch needle is in the directional hole 21, it will abut against the anti-return rod 22.

[0035] It should be noted that one end of the Dutch needle is a relatively rounded torsion spring end, and the other end is a slot end with a certain width. Besides the torsion spring end, when the slot end of the Dutch needle or the side of the Dutch needle abuts against the check rod 22, the check rod 22 can restrict the Dutch needle's continued forward movement, thereby preventing the lower cover from continuing to move forward. Since this patent uses a vibratory feeder 1 to transport the lower cover 9, when the lower cover 9 is limited by the check rod 22 due to its orientation, the driving force of the vibratory feeder 1 on the lower cover 9 will cause the lower cover 9 to rotate on the adjustment hole 21 until the Dutch needle on the lower cover 9 rotates to face the check rod 22. The lower cover 9 then continues to move forward, causing the check rod 22 to abut against the relatively rounded torsion spring end and slide along that end, thus freeing the lower cover 9 from movement and allowing it to be released. At this point, the Dutch needle on the lower cover 9 is correctly oriented and can be directly transported and assembled by the handling robot 8.

[0036] In summary, this patent restricts the movement of the lower cover 9 by setting a check rod 22, and allows movement only when the lower cover 9 is oriented correctly. At the same time, the adjustment hole 21 structure provides sufficient space for the rotation of the lower cover 9 and the installation of the check rod 22. The check rod 22 and the adjustment hole 21 cooperate with each other to realize the automatic adjustment of the Dutch needle in the lower cover 9.

[0037] Furthermore, a pressure rod 23 is rotatably provided on the directional channel 2, with one end of the pressure rod 23 pressing against the directional hole 21. For example... Figure 2 , 3 As shown, a horizontally placed rotating shaft 26 is provided on the adjusting baffle 25. The pressure rod 23 is rotatably connected to the rotating shaft 26. The end of the pressure rod 23 abuts against the lower cover 9 on the adjusting hole 21. The pressure rod 23 is used to limit the lower cover 9 so that the lower cover 9 will not pop out when rotating, thereby increasing the stability of the lower cover 9 conveying.

[0038] Furthermore, the adjusting channel 2 is also provided with a guide groove 27 connected to the adjusting hole 21. The guide groove 27 is elongated and its width is adapted to the width of the Dutch needle to accommodate the Dutch needle. After the lower cover 9 is adjusted by the check rod 22, the lower cover 9 continues to move forward, and at the same time, the Dutch needle on the lower cover 9 falls into the guide groove 27. The guide groove 27 prevents the lower cover 9 from rotating during its continued conveying.
