Description

Technical Field

[0001] The utility model relates to an automatic feeding rivet machine. Background Art

[0002] Riveting machines are crucial automated equipment in industrial production, primarily used for riveting various parts. With the rapid development of the manufacturing industry, the demand for riveting efficiency and automation continues to increase, and automatic riveting machines are becoming the mainstream in the market. Currently, automatic riveting machines on the market typically consist of a workpiece conveying system, a positioning device, a riveting mechanism, and a control system, enabling automated workpiece conveying, positioning, and riveting operations.

[0003] Existing automatic riveting machines primarily use conveyors or robotic arms to transport workpieces. Conveyor systems use belts to transport workpieces to the riveting station, while robotic arms use mechanical arms to grab and place workpieces in the riveting position. These transport methods improve production efficiency and reduce the labor intensity of manual operation.

[0004] However, existing automatic workpiece loading rivet machines have exposed the problem of cumbersome workpiece loading during actual use. Traditional conveyor belt transportation systems require manual placement of workpieces one by one in designated positions, and the spacing and direction between workpieces need to be strictly controlled. If the workpieces are not placed properly, they can easily cause deviation or flipping during transportation, affecting the subsequent riveting accuracy. Although the robotic arm system can achieve precise grasping of workpieces, its grasping mechanism often needs to be specially designed and debugged according to the shape and size of different workpieces. Reprogramming and parameter adjustment are required when changing different workpieces. This process is time-consuming and requires professional operation. Utility Model Content

[0005] The purpose of the utility model is to provide an automatic loading riveting machine, which can automatically input a workpiece into a designated position, thereby reducing design costs and saving labor costs.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] An automatic loading riveting machine includes: a frame, a groove is provided in the middle of the frame, and a rivet device is provided above the groove; conveyor belts are provided on both sides of the groove, and multiple baffles are provided above the conveyor belts; a driving rod is connected to one side of the baffle, and the two driving rods are meshed with gears at opposite positions, and the gears are connected to the driving motor; a through hole is provided in the middle of the two driving rods, and a positioning rod is passed through the through hole, and the bottoms of the two positioning rods are connected to a fixing seat, and the fixing seat is fixedly connected to the frame.

[0008] The utility model is further configured as follows: the two baffles are arranged in a staggered manner.

[0009] The utility model is further configured as follows: the driving motor is a reciprocating stepping motor.

[0010] The utility model is further configured as follows: the reciprocating stepping motor has three states: state one is that the left baffle blocks the movement of the workpiece, and the right baffle does not block the movement of the workpiece; state two is that the left baffle blocks the movement of the workpiece, and the right baffle blocks the movement of the workpiece; state three is that the left baffle does not block the movement of the workpiece, and the right baffle blocks the movement of the workpiece.

[0011] The utility model is further configured as follows: the groove is in a rectangular shape.

[0012] The utility model is further configured such that: the positioning rod provides longitudinal support for the driving rod.

[0013] The utility model is further configured as follows: the reciprocating stepping motor switches back and forth in sequence in three states.

[0014] In summary, the present invention has the following beneficial effects:

[0015] This riveting machine utilizes conveyor belts on either side of the groove, coupled with a vertical movement mechanism for baffles, to automatically transport and position the workpiece. The baffles are driven by a drive rod, which, through a gear transmission, converts the rotational motion of the drive motor into the baffle's lifting motion, enabling the baffles on either side to alternately control the movement of the workpiece. The positioning rod and fixed base provide stable longitudinal support for the drive rod, ensuring reliable baffle movement.

[0016] This design enables workpieces to be automatically placed and stacked in a predetermined sequence, eliminating the need for manual placement and adjustment of individual workpiece positions. A reciprocating stepper motor switches between three states, coupled with the continuous motion of the conveyor belt, to automate the entire process of conveying, positioning, stacking, and riveting workpieces on both sides. This design eliminates the manual commissioning and operator intervention required by traditional riveting machines, reducing both design and labor costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "page", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly indicate the quantity of the technical features indicated. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0025] In the description of this utility model, "plurality" means two or more, unless otherwise clearly defined. In this utility model, unless otherwise clearly defined and defined, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, an indirect connection through an intermediate medium, or it can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0026] The present invention will be described in further detail below with reference to the accompanying drawings.

[0027] like Figure 1 As shown, an automatic loading riveting machine includes a frame 1. A recess 2 is provided in the middle of the frame 1. The recess 2 is rectangular and conforms to the shape of the workpiece (steel plate). A rivet device 3 is provided above the recess 2. The rivet device 3 has the functions of automatic riveting (or rivet-free) and crimping installation, which is a prior art and will not be described in detail here.

[0028] The core technical solutions of this application are as follows:

[0029] like Figure 1 、 Figure 2As shown, a conveyor belt 4 is provided on either side of the groove 2. Workpieces shaped to match the groove 2 can be placed on the conveyor belts 4. A plurality of baffles 5 are provided above the conveyor belts 4. The baffles 5 move up and down to block the movement of the workpieces, allowing the workpieces transported by the two conveyor belts 4 to enter the groove 2.

[0030] A drive rod 6 is connected to one side of the baffle 5. Two drive rods 6 mesh with gears 7 at opposing positions. Gears 7 are connected to a drive motor 8, which drives the gears 7 to rotate. When the drive motor 8 is activated, the gears 7 rotate, which in turn drives the drive rods 6 to move longitudinally, thereby moving the baffle 5.

[0031] The two drive rods 6 have through-holes in their centers. Positioning rods 9 are inserted through these through-holes. A fixing base 10 is connected to the bottom of the two positioning rods 9. The fixing base 10 is fixedly connected to the frame 1. The positioning rods 9 provide longitudinal support for the drive rods 6, allowing them to move up and down in the longitudinal direction.

[0032] Optimally, the two baffles 5 are staggered in position, so that when one baffle 5 is placed above the conveyor belt 4 to hinder the movement of the workpiece, the other baffle 5 will not hinder the movement of the workpiece.

[0033] The driving motor 8 is a reciprocating stepping motor with three states:

[0034] like Figure 3 As shown, state 1: the left baffle 5 blocks the movement of the workpiece, and the right baffle 5 does not block the movement of the workpiece;

[0035] like Figure 4 As shown, state 2: the left baffle 5 blocks the movement of the workpiece, and the right baffle 5 blocks the movement of the workpiece;

[0036] like Figure 5 As shown, state three: the left baffle 5 does not hinder the movement of the workpiece, and the right baffle 5 hinders the movement of the workpiece.

[0037] The driving motor 8 switches back and forth in the above three states in sequence, for example, from state 1 to state 2 to state 3, and then from state 3 to state 2 to state 1.

[0038] The overall working process is as follows:

[0039] 1. Place two corresponding square workpieces at intervals between the baffles 5 on the conveyor belt 4.

[0040] 2. Start the conveyor belt 4 so that the conveyor belt 4 starts to transport the workpiece;

[0041] 3. When the workpiece in the right conveyor belt 4 enters the groove 2 first, the drive motor 8 starts to work, driving the gear 7 to rotate, and then driving the drive rods 6 on both sides to move in the opposite direction, so that the baffle 5 on the right moves down to block the movement of the workpiece, that is, the state changes from state 1 to state 2;

[0042] 4. The left baffle 5 continues to move upward under the action of the driving rod 6, and no longer hinders the movement of the workpiece, so that the workpiece on the left enters the groove 2 and is stacked on the workpiece that has already entered the groove 2, that is, the state changes from state 2 to state 3;

[0043] 5. Afterwards, the driving motor 8 is reversed, so that state 3 is transformed into state 2. At this time, the left and right workpieces cannot enter the groove 2, and the rivet device 3 moves down to perform the riveting process on the stacked workpieces;

[0044] 6. Take out the riveted workpiece and drive the motor 8 to continue working, returning from state 3 to state 1;

[0045] 7. The above process is cycled to automate the loading process and riveting process, thereby reducing labor costs and design costs.

[0046] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
