Description

Technical Field

[0001] This invention relates to the field of transmission device technology, and in particular to a transmission device and method for automatically assembling and stacking parts. Background Technology

[0002] In the fields of industrial production and material handling, automated transport and parts stacking technologies have always received widespread attention as key links in improving production efficiency and reducing labor costs. Existing automated parts stacking transport devices, as well as automated production lines for specific fields such as series battery stack automated stacking production lines, have emerged in this context, aiming to optimize production processes and improve product quality and production efficiency through highly automated technologies.

[0003] Existing automated parts stacking conveyor systems primarily consist of three main components: a conveying system, a stacking actuator, and a control system. The conveying system typically uses a motor-driven conveyor belt to transport dispersed parts from their starting position to the designated stacking area. The stacking actuator relies on a high-precision robotic arm, combined with sensor technology, to accurately grip and stack the parts. The control system, acting as the brain of the entire system, receives preset programs or instructions, coordinates the working rhythm of the conveying system and the stacking actuator, and ensures the smooth operation of the parts transfer and stacking process.

[0004] Specific workflow: Workers first place the parts to be stacked on a conveyor belt in a specific orientation. Driven by a motor, the conveyor belt transports the parts to the designated position. Then, guided by sensors, a robotic arm precisely grips the parts and stacks them according to a preset program for subsequent transportation or processing. Problems and shortcomings: 1. High Demand for Manual Intervention: Traditional equipment relies heavily on manual operation during the parts placement stage. Workers must manually place the parts according to the restricted orientation and make multiple adjustments to ensure neatness. This process is not only inefficient, but also prone to misplacement due to worker fatigue or vibration during transportation, which in turn affects the subsequent stacking quality.

[0005] 2. Insufficient stacking accuracy and stability: Due to the difficulty in ensuring the neatness of manual placement, the robotic arm is prone to problems such as irregular stacking and misalignment when picking up and stacking parts. This not only requires manual adjustments by workers, increasing the uncertainty in the production process, but may also adversely affect the quality and performance of the final product.

[0006] 3. Limited automation and flexibility: Traditional equipment often requires complex adjustments and configurations, and may even need to replace some mechanical parts, when dealing with the stacking requirements of parts of different sizes and shapes. This not only reduces the flexibility of the production line, but also increases the cost and difficulty of equipment maintenance and upgrades.

[0007] Taking the automated series-type battery stacking production line disclosed in CN114447389A as an example, this production line is designed with a highly automated production system to meet the stacking requirements of specific types of batteries such as iron-chromium redox flow batteries. This system covers the entire production process from material loading to finished product unloading. Through the integration of key stages such as endplate assembly loading, battery stack stacking, pressing and tightening, and flipping and unloading, it achieves efficient and precise battery stacking. Although the automated series-type battery stacking production line demonstrates a high degree of automation and precision in specific fields, it still faces some general challenges: 1. Equipment complexity and cost: Highly automated production lines are often accompanied by complex equipment structures and high manufacturing costs, which poses a high investment threshold for small and medium-sized enterprises.

[0008] 2. Maintenance and Upgrade Difficulty: With the continuous changes in production demands, the maintenance and upgrading of production lines have become a major challenge. Traditional equipment requires complex adjustments and configurations to cope with the stacking requirements of parts of different sizes and shapes, increasing maintenance costs and difficulty.

[0009] 3. Versatility and Flexibility: Production lines designed for specific types of batteries may require significant modifications or redesigns to meet the needs of stacking other types of batteries or parts, thus limiting their versatility and flexibility.

[0010] For example, the automatic assembly and stacking parts transfer device proposed in CN120207902A faces the same dilemma as the series-connected battery stack automatic stacking production line disclosed in CN114447389A. The automatic assembly and stacking parts transfer device includes multiple precision components (such as hydraulic components, material transfer components, and weighing components), resulting in a complex equipment structure and high manufacturing costs. The high equipment cost places significant economic pressure on small and medium-sized enterprises when investing in such automated devices, limiting the popularization and application of automation technology. Maintenance requires operation by professional technicians, and spare parts are expensive, leading to persistently high overall maintenance costs. With constantly changing production demands, existing equipment often requires significant modifications or redesigns to cope with new technologies and processes, increasing the difficulty and cost of upgrades.

[0011] In summary, existing automated parts-assembly transfer devices and specialized automated production lines have achieved certain results in improving production efficiency and ensuring product quality. However, they still suffer from problems such as high demand for manual intervention, insufficient stacking accuracy and stability, and limited automation and flexibility. These issues not only affect the overall efficiency of the production line but also hinder the pace of industrial production towards higher levels of automation and intelligence. Therefore, developing a transfer device capable of automatically assembling and stacking parts, and achieving automatic adjustment and positioning during parts transport through integrated innovative design, has become an urgent need to promote the transformation and upgrading of industrial production. Summary of the Invention

[0012] The technical problem to be solved by the present invention is to provide a conveying device and method for automatically coordinating and stacking parts, and to solve the core problems existing in the use of the existing automatic coordinating and stacking parts conveying devices: traditional devices rely on manual placement and adjustment of the parts to ensure neatness, but manual operation is prone to visual fatigue or conveyor vibration, which can cause the parts to be misaligned, resulting in irregular stacking by the robotic arm and requiring secondary manual adjustment. Ultimately, this leads to the defects of inconvenience and low efficiency in the use of the device. At the same time, traditional devices lack automatic cleaning function for the surface of the parts, and the impurities attached to the surface of the parts can easily affect the gripping accuracy and stacking quality of the robotic arm.

[0013] To solve the above-mentioned technical problems, the present invention designs an automatic conveying device for stacking parts, integrating "automatic positioning adjustment" and "automatic cleaning" functions, and its specific structure is as follows: I. Overall Structure of the Device The automatic assembly and stacking parts transfer device of the present invention comprises two parts: a core support structure and functional components, as detailed below: 1. Core support structure: includes a frame, with a motor box fixedly connected to the outer side of one end of the frame. The motor box serves as a power source, and its output end passes through the frame and is fixedly connected to a conveyor belt. The two ends of the conveyor belt are rotatably connected to the inner side of the frame to realize the basic transmission function of the parts.

[0014] 2. Functional Components: The components are arranged around the conveyor belt and frame, including support components, support components, adjustment components, clamping components, positioning components, transmission components, cleaning components, and installation components. These components work together to achieve the two core functions of "positioning and adjustment" and "cleaning".

[0015] II. Specific Structure and Function of Each Functional Component (1) Positioning and adjustment related components: to realize automatic alignment and stable clamping of parts. Supporting components: serving as the mounting base for the positioning and adjustment components, including a first supporting plate fixedly connected to the outer sides of both ends of the conveyor belt, and a second supporting plate fixedly connected to the end of the first supporting plate away from the conveyor belt. The second supporting plate provides mounting carriers for the supporting components and the clamping components respectively, and moves synchronously with the conveyor belt to drive the transmission of parts.

[0016] Support assembly: Used to support parts and expose the lower end of the parts during the gripping stage, including a first electric telescopic rod fixed inside the second support plate near the end of the first support plate, a support plate fixedly connected to the end of the first electric telescopic rod away from the second support plate, and locking blocks inserted inside both ends of the support plate, with the ends of the locking blocks away from the support plate fixed to the second support plate; during operation, the first electric telescopic rod can drive the support plate to move along the guide of the locking blocks, so as to support the parts or expose the lower end (for easy gripping by the robotic arm).

[0017] Adjustment component: used to automatically adjust the horizontal position of the part, including a second electric telescopic rod fixed inside both ends of the support plate, and a first push plate fixedly connected to the end of the second electric telescopic rod away from the support plate; by controlling the retraction or extension of the second electric telescopic rod, the first push plates on both sides can be driven to move closer to or further away from the part synchronously, so as to realize the horizontal clamping adjustment of the part and ensure the part is in a regular position.

[0018] Clamping and positioning components work together to achieve stable clamping and adaptive positioning of parts, preventing misalignment during transport. The clamping component includes a third electrically operated telescopic rod fixed inside the second support plate at the end furthest from the first support plate. The output shaft of the third electrically operated telescopic rod is fixedly connected to a clamping plate. The positioning component includes multiple sets of locking levers inserted inside the clamping plate at the end furthest from the third electrically operated telescopic rod. One end of each locking lever inside the clamping plate is fixedly connected to a spring, and the other end of the spring is fixed to the clamping plate. During operation, the third electrically operated telescopic rod pushes the clamping plate closer to the part. The locking levers first contact the part, and the uncontacted levers continue to move with the clamping plate. The contacted levers are compressed and the springs are compressed. Ultimately, through the adaptive contact of the multiple sets of locking levers and the clamping of the clamping plate, stable positioning of parts of different sizes is achieved.

[0019] (2) Cleaning related components: Enables automatic cleaning of parts surfaces and convenient maintenance of components. Transmission Components: The cleaning components are driven by the conveyor belt, requiring no additional power source. It includes a first gear fixed to the end of the conveyor belt furthest from the motor housing. The end of the first gear furthest from the conveyor belt passes through the frame and is fitted with a protective cover (for protection; the cover is fixed to the frame). A second gear meshes with the outer side of the first gear via a first toothed belt (the end of the second gear closest to the frame is rotatably connected to the frame). A third gear meshes with the end of the second gear furthest from the frame via a second toothed belt (the end of the third gear furthest from the frame is rotatably connected to the protective cover). When the conveyor belt operates, it drives the first gear to rotate. Through the sequential transmission of the first toothed belt, the second gear, and the second toothed belt, the third gear is ultimately driven to rotate, providing power to the cleaning components.

[0020] Cleaning assembly: Used to clean debris attached to the upper side of parts, including a first transmission rod fixed to one end of the third gear, the end of the first transmission rod away from the third gear passing through the guard and connected to a second transmission rod, and a cleaning brush fixedly connected to the outer side of the end of the second transmission rod away from the first transmission rod; when the third gear rotates, the cleaning brush is driven to rotate through the first transmission rod and the second transmission rod to clean the upper surface of the parts passing below.

[0021] Mounting components: Facilitating the disassembly and replacement of the cleaning brush, including a mounting plate fixed to one end of the first drive rod near the second drive rod. An insert plate is inserted into the end of the mounting plate away from the first drive rod (the other end of the insert plate is fixedly connected to the second drive rod). The first and second drive rods are fixed together by bolt threads in their middle sections. To replace the cleaning brush, simply unscrew the bolts and pull the second drive rod to detach the insert plate from the mounting plate. Installation is done by reversing the operation.

[0022] Based on the above-mentioned automatic mating and stacking parts transfer device, the present invention also provides an automatic mating and stacking parts transfer method, which realizes parts transfer, positioning adjustment, cleaning and stacking mating through the following steps: Step 1, Start-up and basic transmission: Start the motor box to drive the conveyor belt to rotate. The conveyor belt synchronously drives the support components and the supporting components, adjustment components, clamping components and positioning components installed on it to operate.

[0023] Step 2, Parts Placement and Position Adjustment: Place the parts to be transferred one by one on the support plate of the support assembly, and start the second electric telescopic rod of the adjustment assembly to retract it and drive the first push plates on both sides to move closer to the parts, so as to straighten the horizontal position of the parts.

[0024] Step 3, Part clamping and positioning: Activate the third electric telescopic rod of the clamping assembly to extend it and push the clamping plate closer to the part. The positioning component's latch and spring adaptively abut against each other, and the clamping plate works together to achieve stable clamping of the part and avoid misalignment during transmission. Then, control the extension of the second electric telescopic rod to drive the first push plate back to its original position.

[0025] Step 4, Exposing and cleaning the lower end of the part: Activate the first electric telescopic rod of the support assembly to move the pallet along the clamping block, exposing the lower end of the part (to facilitate gripping by the robotic arm); when the conveyor belt moves the part to the bottom of the cleaning assembly, the transmission assembly drives the cleaning brush to rotate and clean the debris from the upper surface of the part.

[0026] Step 5, Parts clamping and stacking: The robotic arm, in conjunction with the sensor, clamps the positioned part. At this time, the third electric telescopic rod is activated to retract, moving the clamping plate and the locking rod away from the part and releasing the clamping state. The robotic arm moves the part to the designated position and completes the stacking according to the preset program. The device then enters the next round of parts transfer process simultaneously.

[0027] Step 6, Cleaning brush maintenance: When the cleaning brush is worn or dirty, unscrew the bolts of the mounting component, pull the second transmission rod to detach the insert plate from the mounting plate, replace the cleaning brush, and then install it in reverse.

[0028] The present invention provides a conveying device and method for automatically mating and stacking parts, which has the following beneficial effects: 1.

The present invention adds a positioning adjustment mechanism, including support, bearing, adjustment, clamping and positioning components, which can automatically adjust the position and clamp stably according to the size of the part, avoiding manual adjustment, improving production efficiency and product quality, and reducing labor costs and operational errors.

[0037] 10. This invention introduces a cleaning mechanism, including transmission, cleaning, and installation components. It utilizes the power of a conveyor belt to drive a cleaning brush to sweep the surface of parts, thereby improving cleaning efficiency, ensuring the cleanliness of the parts surface, and providing a good foundation for subsequent stacking work.

[0038] 11.

[0053] Example 2 In another preferred embodiment, based on Embodiment 1, this embodiment provides a method for automatically mating and stacking parts, using the automatic mating and stacking parts conveying device described in Embodiment 2 to realize the automatic conveying, positioning, cleaning, and stacking of small irregularly shaped metal parts. The specific steps are as follows: Step 1: Start the motor box 11, set the servo motor speed to 25r / min, drive the conveyor belt 12 to rotate at a uniform speed, and synchronously drive the support component 2, the support component 3, the adjustment component 4, the clamping component 5, and the positioning component 6 to operate together, ensuring that the movement of each component is coordinated and without jamming.

[0054] Step 2: Manually place the small, irregularly shaped metal parts to be transported one by one onto the tray 32 of the support assembly 3, with the center of gravity of the parts roughly falling in the center area of ​​the tray 32; activate the second electric telescopic rod 41 of the adjustment assembly 4, controlling its retraction by 10~25mm (adapted to the actual size of the parts), driving the first push plates 42 on both sides to move closer to the parts simultaneously. Utilizing the flexible rubber material and anti-slip texture of the first push plates 42, they conform to the sides of the irregularly shaped parts, aligning the horizontal position of the parts and ensuring that the center of the parts is aligned with the center of the tray 32; then activate the third electric telescopic rod 51 of the clamping assembly 5, controlling its extension by 15~25mm, pushing the clamping plate 52 closer to the parts. The locking rods 61 of the positioning assembly 6 first contact the irregularly shaped surface of the parts. The locking rods 61 that have not yet contacted continue to move with the clamping plate 52, while the locking rods 61 that have already contacted are squeezed by the parts and compress the springs 62. Through the adaptive multi-point contact of the 8 sets of locking rods 61 and the flexible clamping of the clamping plate 52, the parts are stably positioned, preventing displacement during transport.

[0055] Step 3: Activate the first electric telescopic rod 31 of the support assembly 3 and control it to retract by 20~30mm, which will drive the pallet 32 ​​to move along the guide block 33, so that the lower end of the part is exposed by 8~10mm, leaving space for the robotic arm to grip.

[0056] Step 4: The conveyor belt 12 moves the positioned part to below the cleaning assembly 8. At this time, the conveyor belt 12 drives the first gear 71 to rotate, which in turn drives the second gear 74 to rotate through the first toothed belt 73. The second gear 74 drives the third gear 76 to rotate through the second toothed belt 75 (at a speed of about 50 r / min). The third gear 76 drives the first transmission rod 81 and the second transmission rod 82 to rotate synchronously, which in turn drives the cleaning brush 83 to rotate at high speed to clean the iron filings, dust and other debris on the upper surface of the part. The cleaning time is about 1.5 seconds, ensuring that the clamping surface and the stacked surface of the part are clean.

[0057] Step 5: The robotic arm, in conjunction with the vision sensor, identifies and positions the part. It then uses a gripper adapted to the irregular shape to grasp the exposed lower part of the part. After the part is firmly gripped, the third electric telescopic rod 51 is activated to retract and return to its original position, causing the clamping plate 52 and the locking rod 61 to move away from the part and release the gripping state.

[0069] Example 4 In another preferred embodiment, based on embodiments 1 to 3, this embodiment provides an automated mating and stacking parts transfer method. It employs an automated mating and stacking parts transfer device adapted to thin sheet metal parts (based on an automated mating and stacking parts transfer device from embodiment 2 with structural optimization). The parts have dimensions of 100-150mm in length, 80-120mm in width, and 1-3mm in thickness, achieving automated transfer, positioning, cleaning, and stacking. The specific steps are as follows: Step 1: Start the motor box 11, set the servo motor speed to 30r / min, drive the conveyor belt 12 to rotate at a uniform speed, and synchronously drive the support component 2, the support component 3, the adjustment component 4, the clamping component 5, and the positioning component 6 to operate. Debug the coordinated movement of each component to ensure no collisions or jamming.

[0070] Step 2: Manually place the thin sheet metal part flat on the support plate 32 of the support assembly 3 (the surface of the support plate 32 is covered with a silicone pad to prevent scratches), ensuring that the edge of the part does not extend beyond the support plate 32; activate the second electric telescopic rod 41 of the adjustment assembly 4, controlling its retraction by 8~18mm (adapted to the width of the part), which drives the first push plates 42 on both sides to slowly approach the part. The first push plates 42 are made of soft silicone to avoid damaging the edges of the sheet metal, and level the horizontal position of the part, ensuring that the center of the part is aligned with the center of the support plate 32; then activate the clamping assembly 5. The third electric telescopic rod 51 extends by 10-20mm, pushing the clamping plate 52 closer to the part. The locking rod 61 of the positioning component 6 (with a soft rubber head at the end) first contacts the surface of the part. The locking rod 61 that has not yet contacted moves slowly with the clamping plate 52. The locking rod 61 that has already contacted is slightly squeezed and compresses the spring 62 (the spring elastic coefficient is 2N / mm to avoid excessive pressure that could cause the part to deform). Through the uniform force of the 12 sets of locking rods 61 and the flexible clamping of the clamping plate 52, the thin sheet-like part is stably positioned, preventing warping or displacement during transmission.

[0071] Step 3: Activate the first electric telescopic rod 31 of the support assembly 3 and control its retraction by 15~25mm. This will drive the pallet 32 ​​to move slowly along the guide block 33, so that the lower end of the part is exposed by 5~8mm. This ensures the stability of the part and provides space for the robotic arm to grip it.

[0072] Step 4: The conveyor belt 12 moves the positioned part to below the cleaning assembly 8. The conveyor belt 12 drives the first gear 71 to rotate, which in turn drives the second gear 74 to rotate via the first toothed belt 73. The second gear 74 drives the third gear 76 to rotate via the second toothed belt 75 (at a speed of about 45 r / min). The third gear 76 drives the first transmission rod 81 and the second transmission rod 82 to rotate, which in turn drives the cleaning brush 83 (ultra-soft nylon bristles) to rotate at a low speed, gently cleaning the dust, oil, and other debris on the upper surface of the part. The cleaning time is about 1 second, avoiding scratching the surface of the part by using bristles that are too hard or rotating too fast.

[0073] Step 5: The robotic arm, in conjunction with the vacuum suction cup gripper (suitable for thin sheet parts), adsorbs the exposed lower part of the part. After the adsorption is stable, the third electric telescopic rod 51 is activated to retract back to its original position, driving the clamping plate 52 and the clamping rod 61 away from the part, releasing the clamping state. The robotic arm then moves the part to the designated stacking area and completes the stacking in a "flat layering" manner (each layer of parts is arranged in parallel, with protective film between layers). The device then simultaneously enters the next round of part transfer process.

[0074] Examples 3 and 4, through the flexible adaptation of the device and the refined operation of the method, realize the non-destructive transmission and stacking of thin sheet metal parts, with precise positioning, clean and gentle operation, effectively avoiding deformation and scratches of parts, and meeting the production needs of thin and light parts.

[0075] In a preferred embodiment, an automatic conveying device for stacked parts automatically adjusts and positions the parts through a support component 2, a support component 3, an adjustment component 4, a clamping component 5, and a positioning component 6, and cleans the parts through a transmission component 7 and a cleaning component 8. The above configuration enables precise positioning and automatic cleaning of parts during the conveying process, reduces manual intervention, improves production efficiency and product yield, and reduces the risk of part damage due to human error, ensuring stable and efficient operation of the production line.

[0076] In a preferred embodiment, the supporting component 3 includes a first electrically operated telescopic rod 31 fixedly connected inside the second support plate 22 near the end of the first support plate 21. A support plate 32 is fixedly connected to the end of the first electrically operated telescopic rod 31 away from the second support plate 22. Locking blocks 33 are inserted into both ends of the support plate 32, with the ends of the locking blocks 33 fixedly connected to the second support plate 22 away from the support plate 32. With this configuration, the support plate 32 can smoothly extend and retract under the drive of the first electrically operated telescopic rod 31, and the locking blocks 33 slide inside the support plate 32, serving both a guiding function and enhancing structural stability. When the first electrically operated telescopic rod 31 extends or retracts, the support plate 32 can precisely adjust its position to meet different support requirements.

[0077] In a preferred embodiment, the adjustment component 4 includes a second electric telescopic rod 41 fixedly connected inside both ends of the pallet 32, and a first push plate 42 fixedly connected to the end of the second electric telescopic rod 41 away from the pallet 32. This arrangement allows the first push plate 42 to move horizontally under the drive of the second electric telescopic rod 41, thereby adjusting the position of the item placed on the pallet 32 ​​to ensure that the item is in a suitable position and to meet the needs of different processing or usage scenarios.

[0078] In a preferred embodiment, the clamping assembly 5 includes a third electric telescopic rod 51 fixedly connected inside the end of the second support plate 22 away from the first support plate 21, and a clamping plate 52 is fixedly connected to the output shaft of the third electric telescopic rod 51. This configuration allows the third electric telescopic rod 51 to drive the clamping plate 52 in a linear reciprocating motion, thereby precisely clamping items of different sizes. The surface of the clamping plate 52 is also provided with anti-slip textures to increase friction with the items, preventing them from slipping during clamping and ensuring stable and reliable operation.

[0079] In a preferred embodiment, the positioning component 6 includes multiple sets of locking rods 61 inserted into the end of the clamping plate 52 away from the third electric telescopic rod 51. A spring 62 is fixedly connected to one end of the locking rod 61 inserted into the clamping plate 52, and the other end of the spring 62 away from the locking rod 61 is fixedly connected to the clamping plate 52. With this configuration, when the locking rod 61 is compressed by external force, the spring 62 contracts, causing the locking rod 61 to retract into the clamping plate 52. After the external force disappears, the spring 62 resets, pushing the locking rod 61 out, allowing it to accurately engage with the corresponding positioning hole. This achieves rapid positioning and stable fixation of the clamping plate 52, ensuring stable operation of the equipment.

[0080] In a preferred embodiment, the transmission assembly 7 includes a first gear 71 fixedly connected to the end of the conveyor belt 12 away from the motor housing 11. The end of the first gear 71 away from the conveyor belt 12 passes through the frame 1. A protective cover 72 is fitted over the outside of the first gear 71, and the end of the protective cover 72 near the frame 1 is fixedly connected to the frame 1. The outer gear of the first gear 71 meshes with a first toothed belt 73, and the inner gear of the end of the first toothed belt 73 away from the first gear 71 meshes with a second gear 74. The end of the second gear 74 near the frame 1 is rotatably connected to the frame. On frame 1; the outer gear of the second gear 74 away from frame 1 meshes with the second toothed belt 75, and the inner gear of the upper end of the second toothed belt 75 meshes with the third gear 76. The end of the third gear 76 away from frame 1 is rotatably connected to the cover 72. The above arrangement makes the transmission component 7 form a multi-stage gear transmission structure. The first gear 71 drives the first toothed belt 73, the first toothed belt 73 drives the second gear 74, and the second gear 74 drives the third gear 76 through the second toothed belt 75, so as to achieve stable and precise power transmission and speed regulation.

[0081] In a preferred embodiment, the cleaning assembly 8 includes a first transmission rod 81 fixedly connected to one end of the third gear 76. A second transmission rod 82 is disposed through the cover 72 at the end of the first transmission rod 81 away from the third gear 76. A cleaning brush 83 is fixedly connected to the outer side of the end of the second transmission rod 82 away from the first transmission rod 81. The mounting assembly 9 includes a mounting plate 91 fixedly connected to the end of the first transmission rod 81 near the second transmission rod 82. A insert plate 92 is inserted into the end of the mounting plate 91 away from the first transmission rod 81. The end of the insert plate 92 away from the mounting plate 91 is fixedly connected to the second transmission rod 82. Bolts 93 are threadedly engaged at the middle ends of the first transmission rod 81 and the second transmission rod 82. This configuration allows the cleaning brush 83 to automatically clean as the third gear 76 rotates. The mounting assembly 9 allows for flexible disassembly and reassembly of the second transmission rod 82 and the cleaning brush 83. When the cleaning brush 83 needs to be replaced or repaired, simply unscrew the bolts 93 and pull out the insert plate 92 to quickly remove the second transmission rod 82 and the cleaning brush 83.

[0082] In the preferred embodiment, in step 2, the adjustment process of the adjustment component 4 is as follows: the second electric telescopic rod 41 is activated to retract, driving the first push plate 42 to clamp the two sides of the part, thereby achieving part positioning. This setup ensures the part remains stable during subsequent processing, reducing errors caused by positional deviations. Simultaneously, the retraction force of the second electric telescopic rod 41 can be precisely controlled, adapting to the positioning requirements of parts of different sizes, further enhancing the versatility and practicality of the solution.

[0083] In the preferred embodiment, in step 4, the driving process of the cleaning component 8 is as follows: the conveyor belt 12 drives the first gear 71 to rotate, which in turn drives the third gear 76 to rotate through the first toothed belt 73, the second gear 74, and the second toothed belt 75 in sequence. This, in turn, drives the cleaning brush 83 to rotate and clean the parts through the first transmission rod 81 and the second transmission rod 82. The above arrangement ensures that the rotation direction of the cleaning brush 83 forms a specific angle with the part conveying direction, which can not only ensure that the surface stains of the parts are thoroughly cleaned, but also prevent the parts from shifting due to excessive rotational force. This effectively improves cleaning efficiency and part processing accuracy, and ensures the smooth progress of subsequent processes.

[0084] In summary, this invention proposes an automatic assembly and stacking part transfer device and method, which effectively solves the core problems existing in the use of existing automatic assembly and stacking part transfer devices: traditional devices rely on manual placement and adjustment of part positions to ensure regularity, but manual operation is prone to visual fatigue or vibration of the conveyor belt 12, which can cause part misalignment, resulting in irregular stacking by the robotic arm and requiring secondary manual adjustment, ultimately leading to inconvenience and low efficiency of the device; at the same time, traditional devices lack automatic cleaning function for debris on the surface of parts, and impurities attached to the surface of parts can easily affect the gripping accuracy and stacking quality of the robotic arm.

[0085] From a technical perspective, this invention proposes an unprecedented automated conveying device for stacking parts. This device integrates multiple functions such as automatic part positioning and adjustment, and automatic cleaning. In the fields of industrial production and material handling, it offers a comprehensive and novel solution for the part conveying and stacking process, contrasting sharply with traditional conveying devices that only possess single functions. Regarding part positioning and adjustment, the unique synergistic effect of the adjustment component 4, clamping component 5, and positioning component 6 achieves adaptive adjustment and stable clamping based on part dimensions, eliminating the need for manual placement or secondary adjustments. This automated positioning and adjustment method is rare in existing technologies, opening up new directions for precise positioning during part conveying.

[0086] Analysis of the design scheme reveals that this invention features a unique structure where the transmission component 7 and the cleaning component 8 work together. Power is transmitted from the conveyor belt 12 to the cleaning component 8, enabling automatic cleaning of debris from the surface of parts without the need for an additional power source. This ingenious design, utilizing existing power for cleaning, is unique among similar devices. Regarding the replacement of the cleaning brush 83, this invention incorporates a dedicated mounting component 9. Through the cooperation of the mounting plate 91, the insert plate 92, and the bolts 93, the cleaning brush 83 can be quickly disassembled and replaced. The operation is simple, and this convenient cleaning brush 83 replacement structure is rare in existing technologies.

[0087] From a value perspective, this invention not only solves the problems of high manual intervention requirements and insufficient stacking accuracy and stability in traditional devices during parts transportation, but also improves the device's performance from multiple dimensions through the collaborative innovation of various components. For example, the automatic positioning and adjustment component 4 improves the regularity of parts placement, and the automatic cleaning component 8 ensures the cleanliness of parts surfaces. Overall, it constructs an efficient, stable, and automated parts transportation and stacking mode. In realizing the automatic parts positioning and adjustment function, it ingeniously utilizes various components such as the first electric telescopic rod 31, the second electric telescopic rod 41, the third electric telescopic rod 51, and the spring 62. Through the stroke adjustment of the first electric telescopic rod 31 and the adaptive structure of the spring 62 in the positioning component 6, the device can adapt to the transportation and positioning needs of parts of different sizes. This flexible size adaptation method has high practical value and pioneering potential in industrial production. The design of the transmission component 7 and cleaning component 8 in this invention not only achieves automatic cleaning of parts but also cleverly utilizes the power of the conveyor belt 12, eliminating the need for an additional power source and reducing energy consumption. This energy-saving and efficient cleaning method represents a significant breakthrough among similar devices and aligns with the concept of green production. The modular design of each component facilitates assembly, maintenance, and future functional expansion. Furthermore, the design of the installation component 9 simplifies the replacement process of the cleaning brush 83, reducing maintenance costs. This innovative concept, focusing on the overall structure and ease of maintenance, improves the versatility and economy of the device and has pioneering significance in the design of industrial production equipment.
