Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please refer to Figures 2 to 13. This utility model provides a technical solution: an assembly device including a frame 1. The frame 1 is equipped with a material tray 2, a feeding assembly 3, a pushing assembly 4, a loading assembly 5, and a positioning assembly 6. The workpiece 100 to be assembled (i.e., a needle-shaped workpiece) is placed in the material tray 2. The material tray 2 conveys the workpiece 100 to the feeding assembly 3 through vibration. The feeding assembly 3 conveys the workpiece to the pushing assembly 4. The pushing assembly 4 pushes the workpiece to the loading assembly 5. At this time, the operator places the workpiece 200 in the positioning assembly 6. The loading assembly 5 inserts the workpiece 100 into the workpiece 200, thus completing the assembly of the workpiece 100 and workpiece 200. Mounting brackets 101 are provided on both sides of the frame 1. Each mounting bracket 101 is equipped with a material tray 2, a feeding assembly 3, a pushing assembly 4, a loading assembly 5, and a positioning assembly 6, which can improve efficiency.

[0037] In this embodiment of the invention, the feeding assembly 3 is connected to the material tray 2. The feeding assembly 3 includes a conveying beam 31, on which a conveying groove 32 is provided. The conveying groove 32 is arranged along the length of the conveying beam 31, with its opening facing upwards. A cover 33 is provided on the conveying groove 32. The feeding assembly 3 uses a high-frequency vibration mode to convey the workpiece 100. The cover 33 can prevent the workpiece 100 from being dislodged from the conveying groove 32, and can be opened for inspection and maintenance when the workpiece 100 becomes blocked. Specifically, to facilitate the smooth conveying of the workpiece 100, the conveying beam 31 is inclined, that is, one end of the conveying beam 31 near the material tray 2 is set higher than the other end, so that the conveying groove 32 forms a slope, and the workpiece 100 slides down the slope towards the pushing assembly.

[0038] In an embodiment of this utility model, the conveying beam 31 is equipped with a first sensor 34, which is located at the entrance of the conveying trough 32 and is used to detect the workpiece 100. For example, if the workpiece 100 is not detected within a set time, the background control system will issue an alarm.

A needle carrier plate 41 is slidably disposed within the first guide rail 44, and the driving end of the first hydraulic cylinder 43 is connected to the needle carrier plate 41. The first hydraulic cylinder 43 drives the needle carrier plate 41 to reciprocate within the first guide rail 44 by extending and retracting.

[0041] In this embodiment of the invention, one end of the conveying beam 31 is connected to the first guide rail 44, and the conveying beam 31 conveys the workpiece 100 into the first guide rail 44. The initial position of the needle-carrying plate 41 is aligned with the conveying beam 31, and the needle-carrying groove 42 is located at the top of the needle-carrying plate 41. When the needle-carrying plate 41 is in its initial position, the needle-carrying groove 42 is aligned with the conveying groove 32. After the workpiece 100 is conveyed out of the conveying groove 32, it enters the needle-carrying groove 42.

[0042] In an embodiment of this utility model, a second sensor 45 is provided on the upper side of the first guide rail 44. The second sensor 45 is used to detect whether the workpiece 100 has been conveyed into the needle carrier groove 42. After detecting the workpiece 100 in the needle carrier groove 42, the first hydraulic cylinder 43 drives the needle carrier plate 41 to move away from the initial position and onto the feeding assembly.

[0043] In an embodiment of this utility model, the feeding component 5 is arranged in parallel with the feeding component 3. The feeding component 5 includes a pusher rod 51 and a pusher hole 52.

One end of the pusher rod 51 is in contact with the pressure sensor 55. The pusher rod 51 is movably disposed within two pusher holes 52.

[0046] In this embodiment of the invention, specifically, the groove wall of the second guide rail 53 is aligned with the groove wall of the first guide rail 44, and the needle carrier plate 41 can move along the first guide rail 44 into the second guide rail 53. A third sensor 59 is provided above the second guide rail 53. The needle carrier plate 41 moves to below the third sensor 59, the needle carrier groove 42 is aligned with the needle push hole 52, the drive motor 58 drives the ball screw 56 to rotate, and the slide table 57 moves closer to the first guide rail 53.

[0047] The second guide rail 53 moves in the direction of the push needle rod 51. The end of the push needle rod 51 moves from the push needle hole 52 near the push needle rod drive assembly to the push needle hole on the other side. The end of the push needle rod 51 passes through the needle carrier groove 42 and pushes the workpiece 100 to the push needle hole 52 on the other side. The workpiece 100 enters the positioning assembly 6 through the push needle hole 52 and is assembled with the workpiece 200.

[0048] In an embodiment of this utility model, the positioning component 6 is located in the vertical direction of the pusher rod 51, and includes a positioning component and a clamping component, for aligning the pin hole of the workpiece 100 to be installed with the pusher hole 52 and stabilizing the workpiece to be installed.
