Description

Technical Field

[0001] This utility model relates to assembly fixtures, and more particularly to an automatic rivet feeding device. Background Technology

[0002] A rivet is a fastener used to securely connect two objects. It is typically made of metal and consists of a head and a shank, with the head having a larger diameter than the shank. Its working principle is as follows: after the shank passes through a hole in the parts to be connected, external force deforms the end of the shank, forming a "riveting head." This riveting head engages with the head to clamp several parts together, thus achieving a non-removable connection. Rivets are widely used due to their high reliability, shock resistance, adaptability to various materials, and ability to be quickly installed even in situations where the back side cannot be accessed.

[0003] Traditionally, using rivets involves manually placing the rivet in the desired location and then firing it with a rivet gun (such as a rivet gun). This causes the rivet shank to deform after passing through the object being joined, thus connecting several objects. However, this method is not only inefficient but also highly prone to safety accidents, posing a significant risk to worker safety.

[0004] To address the issue of manual rivet handling, automated equipment (such as riveting machines) has gradually emerged in the market to replace manual labor. These machines use mechanical devices to automatically grab and fire rivets, which not only improves production efficiency but also avoids the risk of workplace injuries to workers. This helps companies increase their production efficiency and enhance their market competitiveness.

[0005] However, existing automated equipment has the following problems: due to the small size of the rivets, some rivet heads may be set to irregular shapes, which makes it difficult to accurately grasp the rivets. Even if they are grasped by the transfer robot, they may not be placed in the most precise position, resulting in poor riveting quality. Summary of the Invention

[0006] Purpose of the utility model: The purpose of this utility model is to provide a rivet feeding device that can automatically and accurately feed rivets into the riveting point to achieve precise riveting.

[0007] Technical Solution: The present invention discloses an automatic rivet feeding device, comprising a rivet base, wherein a rivet head groove is formed on the top of the rivet base, the shape of which matches the outline of the rivet head. A rivet feeding groove is also provided on the top surface of the rivet base, the rivet feeding groove communicating with the rivet head groove, and a rivet feeding plate is slidably disposed within the rivet feeding groove. The rivet includes a rivet head and a rivet shank, the rivet head being disposed at one end of the rivet shank.

[0008] Furthermore, the shape of the pushing end of the nail feeding plate matches the contour of the rivet head.

[0009] Furthermore, it also includes a nail-feeding cylinder, the output end of which is connected to the nail-feeding plate.

[0010] Furthermore, the output end of the nail feeding cylinder is connected to the nail feeding adapter block, and the nail feeding adapter block is detachably connected to the nail feeding plate.

[0011] Furthermore, it also includes a nail-carrying block, on which a first nail-carrying groove and a second nail-carrying groove are formed. The outlet of the second nail-carrying groove communicates with the first nail-carrying groove. The nail-feeding plate is slidably disposed in the first nail-carrying groove, and the outlet position of the first nail-carrying groove corresponds to the inlet position of the nail-feeding groove.

[0012] Furthermore, the depth of the first rivet groove is the same as the depth of the second rivet groove. This same depth means that when the rivet feeder slides within the first rivet groove, it effectively controls the opening and closing of the exit of the second rivet groove, thereby controlling the entry of the rivet into the first rivet groove. When the end face of the rivet pushed by the rivet feeder is positioned between the entrance of the first rivet groove and the exit of the second rivet groove, the rivet at the foremost position can enter the first rivet groove through the push of the rivet column, and the rivets entering the first rivet groove can be pushed by the rivet feeder. When the end face of the rivet pushed by the rivet feeder is positioned between the exit of the second rivet groove and the rivet head groove, the rivet feeder effectively closes the exit of the second rivet groove.

[0013] Furthermore, it also includes a sliding base, to which the pin seat is slidably connected.

[0014] Furthermore, it also includes a vibratory feeder, the outlet of which is provided with a rivet discharge channel for sequentially discharging rivets. The outlet of the rivet discharge channel is connected to the inlet of the second rivet conveying groove. Several screening devices are provided inside the vibratory feeder, so that the rivets can only enter the rivet discharge channel in the same posture (rivet head down, rivet shank up).

[0015] Beneficial effects: Compared with the prior art, this utility model has the following advantages: 1. After using this utility model, the rivet is accurately pushed into the rivet head groove. Since the shape of the rivet head groove matches the outline of the rivet head, the position of the rivet after being pushed into the rivet head groove is unique, which facilitates the improvement of riveting accuracy in the future; 2. This utility model can also be used in conjunction with other devices (such as a hammer located above the rivet head groove, a robot arm used to transfer other parts). Since the position of the rivet is unique, the robot arm used to transfer other parts can use the rivet as the positioning origin to build other parts on the rivet. After all parts are built, the rivet rod is deformed by pressing down with the hammer to complete the riveting. After the riveting is completed, all parts become a whole, which makes it easier to transfer the whole. Attached Figure Description

Detailed Implementation

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0027] See appendix Figures 1-9 The present invention discloses an automatic rivet feeding device, including a rivet seat 8, a rivet head groove 801 formed on the top of the rivet seat 8, the shape of the rivet head groove 801 matching the outline of the rivet head 601 of the rivet 6, a rivet feeding groove 802 also provided on the top surface of the rivet seat 8, the rivet feeding groove 802 communicating with the rivet head groove 801, a rivet feeding plate 2 slidably disposed in the rivet feeding groove 802, the shape of the pushing end of the rivet feeding plate 2 matching the outline of the rivet head 601 of the rivet 6.

[0028] It also includes a nail feeding cylinder 5, the output end of which is connected to a nail feeding adapter block 3, and the nail feeding adapter block 3 is detachably connected to the nail feeding plate 2.

[0029] It also includes a nail transfer block 4, on which a first nail transfer groove 401 and a second nail transfer groove 402 are provided. The outlet of the second nail transfer groove 402 is connected to the first nail transfer groove 401. The nail feeding plate 2 is slidably disposed in the first nail transfer groove 401. The outlet position of the first nail transfer groove 401 corresponds to the inlet position of the nail feeding groove 802.

[0030] The depth of the first nail feed slot 401 can be the same as the depth of the second nail feed slot 402, or the depth of the first nail feed slot 401 can be slightly deeper than the depth of the second nail feed slot 402, but the depth difference between the depth of the first nail feed slot 401 and the depth of the second nail feed slot 402 should be less than the thickness of the nail feed plate 2. This means that when the nail feeder 2 slides within the first nail groove 401, it effectively controls the opening or closing of the outlet of the second nail groove 402, thereby controlling the entry of the rivet 6 into the first nail groove 401. When the nail feeder 2 pushes the end face of the rivet 6 to a position between the inlet of the first nail groove 401 and the outlet of the second nail groove 402, the rivet 6 at the foremost position can enter the first nail groove 401 through the push of the rivet row 6, and the rivet 6 entering the first nail groove 401 can be pushed by the nail feeder 2. When the nail feeder 2 pushes the end face of the rivet 6 to a position between the outlet of the second nail groove 402 and the nail head groove 801, the nail feeder 2 effectively closes the outlet of the second nail groove 402.

[0031] It also includes a sliding base 7, and a nail seat 8 that is slidably connected to the sliding base 7.

[0032] It also includes a vibratory feeder 1, at the outlet of which a nail discharge channel 101 is provided for sequentially discharging rivets 6. The outlet of the nail discharge channel is connected to the inlet of the second nail transmission groove 402. Several screening devices are provided inside the vibratory feeder 1 so that the rivets 6 can only enter the nail discharge channel 101 in the same posture (nail head 601 down, nail shank 602 up).

[0033] The rivet 6 includes a rivet head 601 and a rivet shank 602, with the rivet head 601 disposed at one end of the rivet shank 602.

[0034] In addition to the aforementioned devices, the entire system may also include a hammer 9 for deforming the rivet rod 602 and a robotic arm for transferring other parts. After the rivet 6 is pushed into the rivet head groove 801, the robotic arm transfers other parts to the rivet 6, and the hammer 9 falls down to deform the rivet rod 602 to complete the riveting.
