Description

Technical Field

[0001] This utility model relates to a needle assembly device, and more particularly to a needle connecting rod assembly machine. Background Technology

[0002] Tattooing involves using a needle dipped in ink to pierce the skin and create patterns or words. To improve efficiency and aesthetics, tattoo pens were developed. A tattoo pen typically consists of a pen body, a motor, and needles. The motor drives the needles through a transmission mechanism to perform high-frequency micro-vibrations, causing the needles to create numerous tiny wounds on the skin's surface, achieving the tattooing effect. The tattoo pen needle consists of a connecting rod and a nozzle. The nozzle comprises a base, a needle sleeve, and a needle shaft. After assembly, workers place the connecting rod onto the nozzle and then use a pressing device to press it in place, completing the assembly of the entire tattoo pen needle. Because the assembly process is primarily manual, the overall efficiency is low. Therefore, existing technologies suffer from low production efficiency. Utility Model Content

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0015] Example. A pin linkage assembly machine, configured as follows: Figure 1-3As shown, the device includes a frame 1, on which a longitudinal conveyor belt 2 is mounted, and a set of evenly distributed fixing clamps 3 are mounted on the conveyor belt 2. Along the material conveying direction, the frame 1 also sequentially includes a needle tip pressing mechanism 4, a connecting rod pressing mechanism 5, and a discharge mechanism 6 located above the conveyor belt. Each of the needle tip pressing mechanism 4, the connecting rod pressing mechanism 5, and the discharge mechanism 6 includes a bracket 7, on which a transverse drive assembly 8 is mounted, and below the transverse drive assembly 8 is a lifting drive hydraulic cylinder 9. The hydraulic cylinder 9 is equipped with an electric clamp 10 at its output end; the fixed clamp 3 includes a top seat 31, a fixed head 32 is provided above the top seat 31, and two symmetrically distributed arc-shaped clamping blocks 311 are provided on the outer edge of the top seat 31, and a clamping gap 312 is provided between the arc-shaped clamping blocks 311 and the fixed head 32; the arc-shaped clamping blocks 311 include a stationary arc block 314 and a moving arc block 315, a compression spring 313 is provided between the stationary arc block 314 and the moving arc block 315, and an inclined guide surface is provided on the upper surface of the moving arc block 315.

[0016] The cooperation between the stationary and moving arc blocks can effectively improve the clamping of the needle tip and ensure the stability of the connecting rod installation.

[0017] The side of the needle tip pressing mechanism 4 is provided with a needle tip conveying assembly 11.

[0018] The connecting rod pressing mechanism 5 is provided with a connecting rod raw material conveying assembly 12 on its side.

[0019] The side of the discharge mechanism 6 is provided with a finished product conveying assembly 13.

[0020] The discharge station of the frame 1 is also equipped with magnets 14 located on both sides of the conveyor belt 2, and a magnetic block 316 that cooperates with the magnets 14 is embedded in the moving arc block 315. The magnets attract the magnetic blocks, so that the moving arc block loses its clamping on the needle nozzle, making it easier for the discharge mechanism to take out the finished product.

[0021] The conveyor belt has conveyor rollers at both ends, one of which is connected to a drive mechanism, enabling the conveyor belt to transport materials.

[0022] The base material conveying assembly, the connecting rod material conveying assembly, and the protective cover material conveying assembly all include a base frame. A conveyor belt is provided above the base frame, and limit frames are provided on both sides of the conveyor belt. The gap between the two limit frames matches the corresponding material.

[0023] A pressure plate is installed below the conveyor belt.

[0024] Each component installation station is equipped with a positioning detection sensor.

[0025] Both ends of the bracket are equipped with limit blocks. When the bracket reaches the limit block, the hydraulic cylinder is positioned to ensure accurate positioning.

[0026] The electric clamp can be a conventional electric clamp, such as a clamp with a double-headed electric cylinder, where the two output ends of the double-headed electric cylinder are equipped with chucks.

[0027] The installation process of this utility model is as follows: The needle tip is placed on the needle tip conveying assembly and conveyed sequentially to the discharge position. The electric clamp of the needle tip pressing mechanism clamps the needle tip. The lifting drive hydraulic cylinder rises, and the lateral drive assembly moves the needle tip to the top of the needle tip pressing position. The conveyor belt conveys the fixed clamp to the needle tip pressing position. Then, the lifting drive hydraulic cylinder descends and places the needle tip on the fixed clamp, completing the needle tip pressing. The conveyor belt conveys the fixed clamp with the needle tip to the next position (i.e., the connecting rod pressing position). The connecting rod pressing mechanism transfers the connecting rod from the connecting rod raw material conveying assembly to the top of this position. Then, the lifting drive hydraulic cylinder presses the connecting rod onto the needle tip, completing the connecting rod pressing. The conveyor belt continues to move, moving the finished product to the discharge position. The discharge mechanism takes out the finished product and transfers it to the discharge conveying assembly.

[0028] The lateral drive assembly is a conventional lead screw assembly.

[0029] When the needle tip is pressed into the top seat, it will come into contact with and squeeze the moving arc block. The moving arc block clamps the base of the needle tip under the action of the compression spring.

[0030] At the discharge station, the magnetic block embedded in the moving arc block loses its clamping force on the needle base under the magnetic force of the magnet. Under the action of the electric clamp and the lifting drive hydraulic cylinder of the discharge mechanism, the needle is lifted and transferred to the corresponding finished product conveying assembly.
