Description

Technical Field

[0001] This utility model relates to the field of PCB wet process technology, and in particular to a multi-type board processing equipment. Background Technology

[0002] In the developing and etching process of PCB (Printed Circuit Board) manufacturing, the DES (Dry Etching and Finishing) equipment is crucial. It mainly consists of a spray system and a conveyor system for transporting the PCB boards. These two parts work together to complete the developing and etching process of the PCB boards. However, most existing conveyor systems on the market currently use a method of placing the workpiece horizontally for transport. This seemingly conventional design has revealed many problems in practical applications.

[0003] First, when a workpiece is placed horizontally and transported, a certain degree of "pool effect" will appear on its surface during the developing and etching process. This is because when the chemical solution is sprayed onto a horizontally placed workpiece, the solution is not easily distributed and flows evenly, forming pool-like areas on the workpiece surface. This pooling phenomenon causes the reaction time and concentration of the chemical solution in that area to differ from other areas, thus severely affecting the uniformity of etching. Uneven etching will prevent the circuits and patterns on the PCB board from being clearly and accurately presented, affecting subsequent processing steps and the final quality of the product.

[0004] Secondly, horizontal conveying methods cannot effectively solve a series of problems caused by direct contact between the workpiece surface and the conveyor rollers. In PCB manufacturing, direct contact friction between the conveyor rollers and the workpiece surface is a critical problem that urgently needs to be addressed, especially for high-requirement products, where it presents a formidable challenge. Take solder resist development as an example: a special, soft, glossy ink is used in the production process. This ink has unique performance and appearance requirements, but when it comes into contact with the conveyor rollers, its soft texture easily leaves roller marks on the surface. These roller marks damage the smoothness and evenness of the solder resist surface, severely affecting the product's appearance quality. In today's increasingly competitive market, the appearance quality of a product often directly impacts customer satisfaction and market competitiveness; therefore, this issue cannot be ignored. Furthermore, when producing particularly fine lines (line width below 35µm), the contact with the conveyor rollers becomes an "invisible killer" in the production process. Because fine lines are inherently fragile, the conveyor rollers can easily scratch or break the dry film during contact and transport with the workpiece surface. Dry film is a crucial material used to protect circuitry during the development and etching process of PCB boards. If the dry film is scratched or broken, it can lead to open circuits and other malfunctions. Open circuits prevent the PCB board from functioning properly, severely impacting product performance and reliability, and may even render the entire product unusable, resulting in significant economic losses for the company.

[0005] Furthermore, existing conveyor systems have a significant drawback: different width conveyors are required to accommodate different workpiece sizes. In actual production, PCB boards come in a wide variety of sizes, necessitating the use of multiple conveyor widths to meet the conveying needs of different workpiece dimensions. Each time a different workpiece size is changed, the conveyor system must be disassembled and reassembled, which is not only cumbersome and time-consuming but also increases equipment maintenance costs and downtime.

The drive wheel has an annular groove on its wheel wall, and the lower end of the workpiece abuts against the annular groove. The drive wheel can drive the workpiece to move along the conveying direction.

[0010] The limiting mechanism includes a first roller assembly. The first roller assembly is provided on both sides of the transmission mechanism. A plurality of first roller assemblies are arranged at intervals along the conveying direction. The first roller assembly includes a first support column and a first follower. The first support column is disposed on the support assembly and extends along the height direction. A plurality of first followers are rotatably disposed on the first support column. The upper end of the workpiece leans against one of the first followers on one side.

[0011] As an optional solution for multi-type plate processing equipment, the annular groove has a V-shaped cross-section; and / or

[0012] The drive wheel can be made of ceramic, metal, or plastic.

[0013] As an optional solution for multi-type plate processing equipment, the limiting mechanism further includes a second roller assembly. The second roller assembly is provided on both sides of the transmission mechanism. The second roller assembly includes a second support column and a second follower. The second support column is disposed on the support assembly and extends along the height direction. A plurality of second followers are rotatably disposed on the second support column. The distance between two adjacent second followers is greater than the distance between two adjacent first followers.

[0014] As an alternative to multi-type plate processing equipment, several second row roller assemblies are arranged at intervals on the support assembly along the conveying direction.

[0015] As an optional solution for multi-type plate processing equipment, the conveying unit also includes a limiting top plate, and the upper ends of the first support column and the second support column are fixedly connected to the limiting top plate.

[0016] As an optional solution for multi-type plate processing equipment, the support assembly includes two support frames, both of which extend along the conveying direction. The transmission mechanism also includes a central rotating shaft, which is rotatably mounted on the two support frames. The drive wheel is fixedly sleeved on the central rotating shaft and located between the two support frames.

[0017] As an optional solution for multi-type plate processing equipment, the end of the central rotating shaft extending out of the support frame is provided with a mounting component. The mounting component includes an integrally connected sleeve part and a mounting part. The central rotating shaft is rotatably disposed in the sleeve part. The mounting part is connected to the support frame. The mounting part has a slot, and the lower end of the first support column is inserted into the slot.

[0018] As an optional solution for multi-type plate processing equipment, the mounting part is provided with a number of slots at intervals along the conveying direction.

[0019] As an optional solution for multi-type plate processing equipment, the support frame is an L-shaped component, including a vertical plate and a horizontal plate. The mounting part is provided with slots at both ends along the conveying direction, and the slots engage with the vertical plate of the support frame.

[0020] As an optional solution for multi-type plate processing equipment, each of the central rotating shafts is provided with a first bevel gear at one end. The transmission mechanism also includes a drive motor, a transmission shaft, and a plurality of second bevel gears fixedly sleeved on the transmission shaft. The output end of the drive motor is connected to the transmission shaft for transmission, and the first bevel gear meshes with the corresponding second bevel gear.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] The multi-type board processing equipment provided by this utility model has first roller assemblies with limit mechanisms on both sides of the transmission mechanism, forming a workpiece conveying space between the two first roller assemblies and the drive wheel. During workpiece conveying, the workpiece is placed vertically, with its lower end abutting against the annular groove of the drive wheel and its upper end leaning against one of the first follower components. The drive wheel can drive the workpiece to move along the conveying direction. When the multi-type board processing equipment is applied to PCB board processing, the spray units on both sides spray the workpiece. Since the workpiece is in an upright state, the sprayed liquid will flow down from the workpiece surface under the action of gravity, avoiding the formation of liquid accumulation on the workpiece surface and eliminating the pooling effect. Because the lower end of the workpiece abuts against the annular groove of the drive wheel and the upper end leans against the first follower component, direct contact between the two planes of the PCB board and external objects can be avoided, protecting the integrity of the PCB board. Since multiple first follower components are rotatably mounted on the first support column, the upper end of the PCB board can abut against the first follower component of the corresponding height. Therefore, different types of PCB boards can be conveyed, expanding the applicability of the equipment. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0042] In the developing and etching process of PCB (Printed Circuit Board) manufacturing, the DES (Developing, Etching, and Stripping) equipment, also known as a DES line or DES system, is crucial. It comprises a spray system and a conveyor system for transporting the PCB boards. These two parts work together to complete the developing process. However, most existing conveyor systems on the market currently use a horizontal placement of the workpiece for transport. This seemingly conventional design has revealed numerous problems in practical applications.

[0043] First, when a workpiece is placed horizontally and transported, a certain degree of "pool effect" will appear on its surface during the developing and etching process. This is because when the chemical solution is sprayed onto a horizontally placed workpiece, the solution is not easily distributed and flows evenly, forming pool-like areas on the workpiece surface. This pooling phenomenon causes the reaction time and concentration of the chemical solution in that area to differ from other areas, thus severely affecting the uniformity of etching. Uneven etching will prevent the circuits and patterns on the PCB board from being clearly and accurately presented, affecting subsequent processing steps and the final quality of the product.

[0044] Secondly, horizontal conveying methods cannot effectively solve a series of problems caused by direct contact between the workpiece surface and the conveyor rollers. In PCB manufacturing, direct contact friction between the conveyor rollers and the workpiece surface is a critical problem that urgently needs to be addressed, especially for high-requirement products, where it presents a formidable challenge. Take solder resist development as an example: a special, soft, glossy ink is used in the production process. This ink has unique performance and appearance requirements, but when it comes into contact with the conveyor rollers, its soft texture easily leaves roller marks on the surface. These roller marks damage the smoothness and evenness of the solder resist surface, severely affecting the product's appearance quality. In today's increasingly competitive market, the appearance quality of a product often directly impacts customer satisfaction and market competitiveness; therefore, this issue cannot be ignored. Furthermore, when producing particularly fine lines (line width below 35µm), the contact with the conveyor rollers becomes an "invisible killer" in the production process. Because fine lines are inherently fragile, the conveyor rollers can easily scratch or break the dry film during contact and transport with the workpiece surface. Dry film is a crucial material used to protect circuitry during the PCB development process. If the dry film is scratched or broken, it can lead to open circuits and other malfunctions. Open circuits prevent the PCB from functioning properly, severely impacting product performance and reliability, and may even render the entire product unusable, causing significant economic losses to the company.

[0045] Besides the two situations mentioned above, direct contact between the conveyor rollers and the workpiece surface also presents the problem of foreign matter from the rollers sticking to the workpiece surface. During the production process, the surface of the conveyor rollers may become contaminated with various foreign matter, such as dust, oil, and metal shavings. When the rollers come into contact with the workpiece surface, these foreign matter can easily stick to the workpiece surface, causing a series of abnormal problems such as incomplete etching and residual copper. Incomplete etching will result in unclear edges of circuits and patterns on the PCB board, affecting the accuracy and stability of the circuits; residual copper will leave copper foil in areas where conductivity is not required, causing short circuits and other faults, seriously affecting the quality and safety of the product.

[0046] Furthermore, existing conveyor systems have a significant drawback: different width conveyors are required to accommodate different workpiece sizes. In actual production, PCB boards come in a wide variety of sizes, necessitating the use of multiple conveyor widths to meet the conveying needs of different workpiece dimensions. Each time a different workpiece size is changed, the conveyor system must be disassembled and reassembled, which is not only cumbersome and time-consuming but also increases equipment maintenance costs and downtime. Moreover, frequent conveyor changes can lead to decreased equipment precision, affecting workpiece conveying stability and development quality, further reducing development efficiency.

[0047] To eliminate the pooling effect during the developing and etching process and prevent liquid accumulation on the workpiece surface; to avoid direct contact between the two planes of the PCB board and the conveyor rollers during transport, thus protecting the integrity of the PCB board; and to accommodate boards of different widths, expanding the equipment's applicability, this embodiment provides a multi-type board processing device. The following description, in conjunction with... Figures 1 to 6 The specific content of this embodiment will be described in detail. It should be noted that the conveying direction mentioned in this embodiment is... Figure 2 The X direction in this embodiment refers to the height direction. Figure 2 The Z direction in the equation.

[0048] The multi-type plate processing equipment in this embodiment includes a conveying unit 100 and a spraying unit 200. Spraying units 200 are provided on both sides of the conveying unit 100, forming a comprehensive, three-dimensional processing structure. The spraying units 200 located on both sides of the conveying unit 100 are key components in realizing the plate processing function. They can simultaneously spray vertically placed workpieces 300 from all directions. The spraying units 200 control the flow rate, pressure, and spray angle of the spray liquid to ensure that the spray liquid evenly covers the surface of the workpiece 300, thereby achieving efficient processing of the workpiece 300. The conveying unit 100 includes a transmission mechanism and a limiting mechanism, which work together to ensure the stable and orderly transmission of the workpiece 300. The transmission mechanism includes a support component 1 and drive wheels 2. The support component 1 extends along the conveying direction and provides stable support for the entire transmission process. Multiple drive wheels 2 are arranged in an orderly manner along the conveying direction and rotated on the support component 1. These drive wheels 2 have annular grooves 201 on their wheel walls. When workpiece 300 is placed on the conveying mechanism, its lower end abuts against the annular groove 201. Driven by the rotation of the drive wheel 2, friction is generated between the drive wheel 2 and the workpiece, thereby driving workpiece 300 to move smoothly along the preset conveying direction. This design not only ensures sufficient power for the conveying of workpiece 300, but also maintains a stable posture of workpiece 300 during conveying through the positioning effect of the annular groove 201, avoiding conveying deviation caused by shaking. The limiting mechanism includes a first row of roller assemblies 3. The first row of roller assemblies 3 are symmetrically arranged on both sides of the conveying mechanism. Several first row of roller assemblies 3 are arranged at intervals along the conveying direction, forming a series of reliable limiting barriers. Each first row of roller assembly 3 includes a first support column 301 and a first follower 302. The first support column 301 is firmly set on the support assembly 1 and extends along the height direction, providing a stable support base for the first follower 302. Multiple first followers 302 are rotatably set on the first support column 301. This rotatable design gives the first follower 302 flexible adaptability. When the workpiece 300 is conveyed, the upper end of the workpiece 300 leans against the first follower 302 on one side. The first follower 302 will rotate freely according to the conveying action of the workpiece 300, which not only provides stable support for the workpiece 300, but also avoids damage to the surface of the workpiece 300 due to fixed friction.

[0049] When this multi-type board processing equipment is applied to PCB board developing, its unique structural design demonstrates significant technical advantages. In traditional horizontal conveying methods, liquid easily accumulates on the PCB board surface, creating a pooling effect that leads to uneven distribution of the chemical solution, thus affecting the uniformity and quality of developing and etching. This equipment, however, uses a vertically placed workpiece 300, coupled with spray units 200 on both sides for spraying. The sprayed liquid flows smoothly down the surface of the workpiece 300 under gravity, preventing liquid accumulation on the board surface and completely eliminating the pooling effect. This ensures clear and accurate rendering of circuits and patterns, greatly improving the quality and consistency of developing and etching, and laying a solid foundation for subsequent processing steps.

[0050] In the PCB manufacturing process, the integrity of the board surface is crucial. In traditional conveying methods, the two planes of the PCB often come into direct contact with external objects, easily leaving wheel marks, causing foreign matter to stick, and even resulting in residual copper, severely affecting the appearance and performance of the PCB. The innovative design of this equipment cleverly solves this problem. The lower end of the workpiece 300 only abuts against the annular groove 201 of the drive wheel 2, while the upper end of the workpiece 300 leans against the first follower 302. This design prevents the two planes of the PCB from directly contacting external objects, effectively protecting the integrity of the PCB. Whether for ordinary PCBs or high-requirement special PCBs, it ensures that they are not damaged during conveying, reducing the defect rate and improving the product qualification rate and quality stability.

[0051] With the rapid development of the electronics industry, the types and specifications of PCB boards are becoming increasingly diverse. Traditional processing equipment often only adapts to specific types or sizes of PCB boards, failing to meet diverse production needs. This equipment, however, expands its applicability through ingenious design. Because multiple first follower components 302 are rotatably mounted on the first support column 301, the upper end of the PCB board can abut against the corresponding first follower component 302 according to its own height. This means that different types of PCB boards, regardless of their size or thickness, can find suitable support and limiting methods in this equipment, achieving stable conveying. This flexible adaptability allows the equipment to be widely used in the production of various types of PCB boards, reducing equipment investment costs and improving production efficiency.

[0052] During the conveying of workpiece 300, the magnitude of friction directly affects the surface quality of workpiece 300 and the service life of the equipment. In this equipment, rolling friction is used between workpiece 300 and the first follower 302. Compared with traditional sliding friction, rolling friction significantly reduces frictional force. This not only reduces the heat generated by friction and decreases the wear on the surface of workpiece 300, effectively protecting the contact surface of workpiece 300 and extending its service life; it also reduces energy consumption, lowers operating costs, and improves the overall performance and reliability of the equipment.

[0053] Furthermore, the annular groove 201 has a V-shaped cross-section; and / or the drive wheel 2 is made of ceramic, metal, or plastic. When the lower end of the workpiece 300 is placed in the V-shaped annular groove 201, the two side walls of the V-shape form a natural guiding and positioning structure. Due to the symmetry of the V-shape, regardless of any slight offset of the workpiece 300 during placement, the lower end of the workpiece 300 will be subjected to lateral forces from the two side walls of the V-shape of the annular groove 201 as the drive wheel 2 rotates and moves the workpiece 300. These forces balance each other, automatically guiding the lower end of the workpiece 300 to the center position of the annular groove 201, thereby achieving the centering effect of the workpiece 300. This automatic centering function greatly improves the stability and accuracy of the workpiece 300 conveying, avoiding conveying failures caused by workpiece 300 offset, such as jamming or falling. Meanwhile, the V-shaped opening design limits the lateral movement range of the workpiece 300 to a certain extent. When the workpiece 300 is subjected to minor external disturbances, the V-shaped groove can quickly pull the workpiece back to the center position, preventing it from falling. This reliable anti-fall mechanism enables the equipment to operate stably in high-speed, continuous production environments, greatly improving production efficiency and equipment reliability. When the drive wheel 2 is made of ceramic, the ceramic material has extremely high hardness and wear resistance, making the drive wheel 2 made of ceramic less prone to wear during long-term operation and able to maintain stable dimensions and shape. In production environments such as PCB board developing, various chemicals may be encountered. The ceramic material also has good corrosion resistance, resisting the erosion of chemicals and extending the service life of the drive wheel 2. In addition, the surface of the ceramic material is smooth, and the coefficient of friction between it and the workpiece is low, which can reduce wear on the workpiece and protect the surface quality of the workpiece. When the drive wheel 2 is made of metal, the metal drive wheel 2 can provide sufficient support and transmission capacity to ensure stable workpiece conveying. At the same time, the metal material can be manufactured into a high-precision drive wheel 2 through precision machining processes, ensuring the dimensional accuracy and surface quality of the annular groove 201, further improving the positioning accuracy and conveying stability of the workpiece. When the drive wheel 2 is made of plastic, the plastic drive wheel 2 has high corrosion resistance and wear resistance, and can work in acid and alkaline environments for a long time; it is easy to shape and process, which is conducive to mass production; and the lightweight characteristics of plastic material can reduce energy loss in the transmission process.

[0054] Furthermore, the limiting mechanism also includes a second row of roller assemblies 4. Second row of roller assemblies 4 are provided on both sides of the transmission mechanism. Each second row of roller assemblies 4 includes a second support column 401 and a second follower 402. The second support column 401 is disposed on the support assembly 1 and extends along the height direction. Multiple second followers 402 are rotatably disposed on the second support column 401, and the distance between two adjacent second followers 402 is greater than the distance between two adjacent first followers 302. In this embodiment, first row of roller assemblies 3 are provided at both the beginning and end of the transmission mechanism, and multiple first row of roller assemblies 3 are spaced apart along the conveying direction in the middle section of the transmission mechanism. The second row of roller assemblies 4 are also arranged in the middle section of the transmission mechanism to assist in the conveying of the workpiece. At the beginning of the transmission mechanism, the first row of roller assemblies 3 provide initial positioning and guidance for the workpiece, enabling it to accurately enter the conveying track. As the workpiece moves on the transmission mechanism, the first row of roller assemblies 3 and the second row of roller assemblies 4 in the middle section can alternately function. The first row of rollers, 3, with its dense arrangement, can limit and adjust the workpiece, ensuring it remains on the correct conveying path. The second row of rollers, 4, with its larger follower spacing, can accommodate workpieces of different sizes, providing additional support and stability. Especially when handling larger workpieces, the second row of rollers 4 can fill in for the first row of rollers 3, preventing the workpiece from tilting or falling due to instability or external forces. At the end of the conveying mechanism, the first row of rollers 3 again plays a crucial role, ensuring the workpiece leaves the mechanism smoothly and accurately for the next process. This comprehensive limiting design significantly improves the stability of workpiece conveying, reducing production failures and product quality issues caused by unstable conveying.

[0055] Furthermore, several second-row roller assemblies 4 are arranged at intervals along the conveying direction on the support assembly 1. When the workpiece moves on the conveying mechanism, each second-row roller assembly 4 applies a limiting force and a supporting force to the workpiece at a specific height position. During the movement, the workpiece is always subjected to uniform limiting and supporting effects, effectively avoiding workpiece deviation caused by uneven local force. Even if the workpiece is subjected to minor external disturbances during the conveying process, such as airflow fluctuations or slight equipment vibrations, the spaced-apart second-row roller assemblies 4 can promptly adjust and correct the workpiece, ensuring that the workpiece always stays on the correct conveying path, greatly reducing the risk of workpiece falling and improving the safety and reliability of the conveying process.

[0056] Furthermore, the conveying unit 100 also includes a limiting top plate 5, and the upper ends of the first support column 301 and the second support column 401 are fixedly connected to the limiting top plate 5. The limiting top plate 5 is made of high-strength, high-rigidity materials, such as high-quality alloy steel or high-strength aluminum alloy. During the operation of the conveying unit 100, it will be subjected to various external forces, such as the weight of the workpiece, vibration during the conveying process, and external collisions. The setting of the limiting top plate 5 is like building a sturdy roof for the conveying unit 100, tightly connecting the first support column 301 and the second support column 401 together to form a stable frame structure. This frame structure can effectively disperse and transmit external forces, making the force on each component more uniform and reducing deformation and damage caused by excessive local force. For example, when conveying heavy workpieces, part of the workpiece's weight is transferred to the first support column 301 and the second support column 401 through the first roller assembly 3 and the second roller assembly 4. The limiting top plate 5 then distributes these forces throughout the entire frame structure, thereby preventing individual support columns from bending or breaking due to excessive force. This greatly improves the overall stability of the conveying unit 100 and ensures the smooth operation of the conveying process.

[0057] Furthermore, the support assembly 1 includes two support frames 101, both extending along the conveying direction. This elongated design provides stable and continuous support for the entire transmission mechanism. The support frames 101 are typically made of high-strength, high-rigidity materials, such as high-quality steel or aluminum alloy, to ensure they do not deform or break under heavy loads. The transmission mechanism also includes a central rotating shaft 6, which is rotatably mounted on the two support frames 101. The drive wheel 2 is fixedly mounted on the central rotating shaft 6 and located between the two support frames 101. The two support frames 101 extending along the conveying direction form a stable frame structure for the entire transmission mechanism. During transmission, the weight of the workpiece, vibrations during transport, and external interference forces all act on the support frames 101. Because the support frames 101 have sufficient length and strength, they effectively disperse these forces, reducing local stress concentration and thus avoiding instability caused by structural deformation. The central rotating shaft 6, rotatably mounted on the two support frames 101, further enhances the structural stability. The two support frames 101 provide bidirectional support for the central rotating shaft 6, limiting its radial and axial displacement and ensuring stable rotation within a specified range. This stable structural design ensures the transmission mechanism remains smooth during long-term operation, reducing workpiece swaying and offset during transport and improving conveying quality.

[0058] Furthermore, a mounting component 7 is provided at one end of the central rotating shaft 6 extending out of the support frame 101. The mounting component 7 includes an integrally connected sleeve portion 701 and a mounting portion 702. The central rotating shaft 6 is rotatably disposed within the sleeve portion 701, and the mounting portion 702 is connected to the support frame 101. The mounting portion 702 has a slot 7021, into which the lower end of the first support column 301 can be inserted when the first support column 301 is installed. The mounting component 7 is manufactured using an integral molding process, and the mounting portion 702 plays an important role in connecting with the support frame 101 and providing installation positions for the first support column 301 and the second support column 401.

[0059] Furthermore, the mounting section 702 is provided with a number of slots 7021 at intervals along the conveying direction. Different specifications of workpieces or different conveying requirements often have different requirements for the installation position of the first support column 301 and the second support column 401. The arrangement of multiple slots 7021 allows the operator to freely adjust the position of the first support column 301 and the second support column 401 according to actual needs, thereby meeting diverse production requirements.

[0060] Furthermore, the support frame 101 is an L-shaped component, including a vertical plate and a horizontal plate. The mounting part 702 has slots 7022 at both ends along the conveying direction, which engage with the vertical plate of the support frame 101. The horizontal plate supports the entire transmission mechanism; its large contact area evenly distributes the weight borne by the transmission mechanism, transferring the load to other supporting structures and ensuring the stability of the transmission mechanism during operation. These slots 7022 achieve precise engagement with the vertical plate of the support frame 101. The cooperation between the slots 7022 and the vertical plate of the support frame 101 ensures a firm and stable connection between the mounting part 702 and the support frame 101, preventing loosening. This engagement method not only facilitates quick and easy installation, greatly shortening the installation and commissioning time of the equipment, but also facilitates disassembly and maintenance of the mounting part 7 and the support frame 101 during subsequent use, improving the maintainability of the equipment.

[0061] Furthermore, each central rotating shaft 6 is equipped with a first bevel gear 8 at one end. During installation, the first bevel gear 8 and the central rotating shaft 6 are connected by an interference fit or a key to ensure a tight fit and prevent loosening or slippage during operation, thereby achieving efficient power transmission. The transmission mechanism also includes a drive motor 9, a transmission shaft 10, and multiple second bevel gears 11 fixedly sleeved on the transmission shaft 10. The output end of the drive motor 9 is connected to the transmission shaft 10. The first bevel gear 8 meshes with the corresponding second bevel gear 11 to form a bevel gear transmission pair. The drive motor 9 serves as the power source for the entire transmission mechanism. In this transmission mechanism, the drive motor 9 drives the transmission shaft 10 to rotate, and the multiple second bevel gears 11 on the transmission shaft 10 rotate simultaneously, thereby driving the first bevel gears 8 on each meshing central rotating shaft 6 to rotate, achieving synchronous transmission of multiple central rotating shafts 6. This multi-axis synchronous transmission design enables the various conveying units 100 on the transmission mechanism to operate in a coordinated manner, avoiding problems such as uneven material conveying and jamming caused by inconsistent speeds between different shafts. For example, on an automated production line, multiple drive wheels 2 need to start and stop simultaneously and maintain the same linear speed to ensure that materials can be smoothly and accurately transported from one workstation to the next. The multi-axis synchronous transmission function of the bevel gear transmission system can well meet this requirement, improving the overall operating efficiency of the production line and product quality.
