Description

Technical Field

[0001] This utility model belongs to the field of suspension stabilizer bar processing technology, and more specifically, it relates to a suspension stabilizer bar product marking and coding mechanism. Background Technology

[0002] In the manufacturing process of suspension stabilizer bars, marking and coding is a crucial step. Its core requirement is to precisely print customer-specific marking characters on the outer surface of the stabilizer bar's steel wires using specialized paint. To achieve efficiency and precision in this process, a dedicated suspension stabilizer bar marking and coding mechanism is necessary. Currently available such mechanisms mainly consist of a frame, fixtures, a drive mechanism, and a coding mechanism. Their working logic is as follows: First, the fixture quickly and securely limits and fixes the suspension stabilizer bar, ensuring no displacement deviation during coding. Then, the drive mechanism moves the coding mechanism within the frame along a preset trajectory, ultimately completing the precise coding operation on the outer surface of the stabilizer bar's steel wires.

[0003] The existing application number CN202221311203.9 relates to the technical field of inkjet printers, and in particular to a PVC pipe marking inkjet printer. The printer places the pipe on a conveyor wheel, and by activating a first motor and driving through a first transmission box, the pipe is conveyed from right to left. A first support wheel and two sets of second support wheels support the pipe. Then, an inkjet printing mechanism prints the markings onto the pipe, and a discharge device vents the pipe from the top of the workbench, thereby improving the stability of the pipe during printing and the practicality of the equipment. The printer includes an inkjet printing mechanism and a conveying device. The inkjet printing mechanism is mounted on the conveying device, which transports the pipe, and the inkjet printing mechanism prints the markings onto the pipe. The conveying device includes a workbench, a base plate, multiple sets of frames, conveyor wheels, a first support wheel, two sets of second support wheels, a first transmission box, a first motor, and a discharge device. The discharge device is mounted on the top of the workbench, and the base plate is mounted on the discharge device. The bottom ends of the multiple sets of frames are connected to the top of the base plate.

[0004] Based on the above, existing suspension stabilizer bar marking and coding mechanisms are cumbersome due to the large weight of the products and the extremely high requirements for surface coating defects. After marking a set of suspension stabilizer bars, operators must first disassemble the processed products and then re-clamp the next set to be marked. The entire loading and unloading process is tedious and increases the frequency of manual intervention. Moreover, during the handling of marked products off the production line, the surface coating is easily damaged by bumps and friction, which can affect the high standards of product appearance quality and pose a potential threat to the product qualification rate. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a suspension stabilizer bar product marking and coding mechanism. This addresses the shortcomings of existing mechanisms, which, due to the large weight of the products and the extremely high requirements for surface coating defects, necessitate that operators disassemble and reassemble the processed products after each set of stabilizer bars has been marked. This cumbersome loading and unloading process increases the frequency of manual intervention. Furthermore, during the handling of marked products off the production line, the surface coating is easily damaged by bumps and friction, potentially affecting the high standards of product appearance and posing a threat to the product qualification rate.

[0006] The purpose and function of this utility model's product marking and coding mechanism for suspension stabilizer bars are achieved through the following specific technical means: A product identification coding mechanism for suspension stabilizer bars includes a conveyor body, movable rollers, a conveyor chain, a conveyor drive mechanism, a mounting plate, a conveyor assembly, and a coding assembly. Four sets of movable rollers are bolted to the bottom of the conveyor body. Two sets of the conveyor chain are installed inside the conveyor body on both sides. The conveyor drive mechanism is installed inside the conveyor body. The mounting plate is welded to the left and right sides of the conveyor body. The conveyor assembly is located inside the conveyor body. The coding assembly is located on the upper part of the mounting plate.

[0007] Furthermore, the conveying assembly includes: V-shaped positioning plates and V-shaped grooves. Multiple sets of V-shaped positioning plates are arranged, and the multiple sets of V-shaped positioning plates are respectively arrayed on the outside of two sets of conveyor chains. Multiple sets of V-shaped grooves are arranged, and the multiple sets of V-shaped grooves are opened inside the multiple sets of V-shaped positioning plates. A set of stabilizing rods is placed inside each pair of V-shaped grooves in opposite positions.

[0008] Furthermore, the coding assembly includes a support bracket and a controller body, wherein the support bracket is bolted to the upper part of the mounting plate; and the controller body is bolted to the top of the support bracket.

[0009] Furthermore, the coding assembly also includes: a mounting bracket, a coding drive mechanism, and a coding printhead. The mounting bracket is bolted to the inside of the support bracket; the coding drive mechanism is fixedly installed inside the mounting bracket; and the coding printhead is installed inside the coding drive mechanism.

[0010] Furthermore, the coding assembly also includes a position detection switch, which is bolted to the bottom of the mounting bracket.

[0011] Compared with the prior art, the present invention has the following beneficial effects: Firstly, this invention features a conveying assembly. Multiple sets of positioning plates with V-grooves are arrayed on the outer side of the conveyor chain, and the precise fit between the V-shaped structure and the circular body of the stabilizing rod achieves reliable positioning. The symmetrical inclined contact not only prevents displacement caused by vibration during conveying but also disperses pressure to prevent damage to the surface coating. Combined with the continuous operation of the conveyor chain, this forms an automated conveying flow, replacing the traditional manual clamping method, reducing the tedious operation of loading and unloading, and lowering the frequency of manual intervention.

[0012] Secondly, this invention features a coding component that uses a photoelectric sensor-based position detection switch to monitor the product's location in real time, enabling precise linkage between conveying and coding in conjunction with a PLC controller. The machine automatically stops when the stabilizing rod reaches the workstation, and the coding drive mechanism drives the printhead to complete the printing along a preset trajectory. Conveying is immediately restarted after completion, forming a continuous production closed loop. The centrally located support bracket also reserves space for subsequent processes, allowing for the integration of functions such as touch-up painting, labeling, and inspection.

[0013] This invention offers advantages such as reduced manual intervention, improved coding efficiency, and ease of use. By combining mechanized continuous conveying with automated coding, it achieves integrated operation of the stabilizer bar from material loading to processing, significantly improving production efficiency. Simultaneously, it reduces product transfer links, fundamentally lowering the risk of surface coating damage from impacts, balancing efficient production with quality assurance, and significantly enhancing operational convenience.

[0018] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0019] Example 1: As attached Figure 1 To be continued Figure 3 As shown: This utility model provides a product marking and coding mechanism for suspension stabilizer bars, including a conveyor body 1, movable rollers 2, conveyor chains 3, conveyor drive mechanism 4, mounting plate 6, and conveyor components. Four sets of movable rollers 2 are bolted to the bottom of the conveyor body 1. Two sets of conveyor chains 3 are installed on both sides inside the conveyor body 1. The conveyor drive mechanism 4 is installed inside the conveyor body 1. The mounting plate 6 is welded to the left and right sides of the conveyor body 1. The conveyor components are located inside the conveyor body 1.

[0020] The conveying assembly includes: V-shaped positioning plates 5 and V-shaped grooves 501. Multiple sets of V-shaped positioning plates 5 are arranged, and the multiple sets of V-shaped positioning plates 5 are respectively arrayed on the outside of the two sets of conveying chains 3. Multiple sets of V-shaped grooves 501 are arranged, and the multiple sets of V-shaped grooves 501 are opened inside the multiple sets of V-shaped positioning plates 5. A set of stabilizing rods is placed inside each pair of V-shaped grooves 501 in opposite positions.

[0021] The specific usage and function of this embodiment are as follows: The conveyor body 1 can move flexibly with the help of four sets of movable rollers 2 with locking function at the bottom. The equipment position can be quickly adjusted according to the production layout needs of the workshop, improving space adaptability. After starting, the conveyor drive mechanism 4 drives the two sets of conveyor chains 3 to operate synchronously, thereby driving multiple sets of V-shaped positioning plates 5 installed on the outside of the conveyor chains 3 to form a continuous conveying flow.

[0022] Because the stabilizer bar adopts a circular rod-shaped structure, the V-shaped groove 501 opened on the V-shaped positioning plate 5 can form a precise fit with the surface of the stabilizer bar through the inclined surfaces on both sides. It uses the principle of triangular stability to achieve reliable positioning, which not only avoids axial or radial displacement caused by vibration and turning during transportation, but also disperses pressure through symmetrical contact, preventing squeezing damage to the coating on the surface of the stabilizer bar, and ensuring that the stabilizer bar always maintains a stable posture during transportation.

[0023] Example 2: Based on Example 1, such as Figures 1 to 3 As shown, it also includes: a coding component, which is mounted on the upper part of the mounting plate 6.

[0024] The coding assembly includes a support bracket 7 and a controller body 8. The support bracket 7 is bolted to the upper part of the mounting plate 6, and the controller body 8 is bolted to the top of the support bracket 7.

[0025] The coding assembly also includes: a mounting bracket 9, a coding drive mechanism 10, and a coding head 11. The mounting bracket 9 is bolted to the inside of the support bracket 7; the coding drive mechanism 10 is fixedly installed inside the mounting bracket 9; and the coding head 11 is installed inside the coding drive mechanism 10.

[0026] The coding assembly also includes a position detection switch 12, which is bolted to the bottom of the mounting bracket 9.

[0027] The specific usage and function of this embodiment are as follows: The controller body 8 has a built-in PLC control system, which constitutes the core of the automated control of the entire inkjet printing process. When the conveyor chain 3 drives the V-shaped positioning plate 5 and the stabilizing rod in the V-shaped groove 501 to be conveyed at a constant speed, the position detection switch 12 installed at the bottom of the mounting bracket 9 continuously monitors the conveying path using photoelectric sensing technology. The infrared light emitted by the position detection switch 12 forms a detection light path. When the stabilizing rod arrives at the inkjet printing station with the conveyor flow, the stabilizing rod body blocks the light path. The receiving end generates an electrical signal due to the interruption of light and feeds it back to the PLC controller.

[0028] The PLC controller immediately triggers a linkage command: first, it stops the conveyor drive mechanism 4, ensuring the stabilizer bar is precisely positioned at the coding station; then, it starts the coding drive mechanism 10, driving the inkjet printer nozzle 11 to move along a preset trajectory, accurately printing the characters onto the steel wire surface of the stabilizer bar. After the coding operation is completed, the coding drive mechanism 10 sends a completion signal to the PLC, which then restarts the conveyor drive mechanism 4, allowing the coded stabilizer bar to be conveyed to the next station, achieving continuous production.

[0029] Furthermore, the support bracket 7 adopts a structural design that is centrally located within the conveyor body 1, reserving space for subsequent process expansion. By adding stations such as touch-up painting, QR code labeling, and end hole inspection along the conveying path, the stabilizer bar can be integrated into a single operation from conveying to multi-process processing, significantly improving production efficiency while reducing manual intervention and product transfer links. This fundamentally reduces the risk of damage to the surface coating caused by handling bumps and knocks, balancing efficient production with quality assurance.

[0030] The following points should be noted in this article: 1. The accompanying drawings of this embodiment only involve the structures involved in this embodiment; other structures can refer to the general design.

[0031] 2. Where there is no conflict, this embodiment and the features in the embodiment can be combined with each other to obtain new embodiments.

[0032] The above are merely specific implementations of this embodiment, but the protection scope of this embodiment is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this embodiment should be included within the protection scope of this embodiment. Therefore, the protection scope of this embodiment should be determined by the protection scope of the claims.
