[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0043] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0044] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0045] See also Figures 1 to 8 As shown in the embodiment of this utility model, a positioning mechanism is provided, including: a roller conveyor assembly 1, a lifting and guiding assembly 2, and a lifting receiving platform 3; the roller conveyor assembly 1 has at least two conveying channels for transporting the object to be processed to the picking station 11; the lifting and guiding assembly 2 is disposed below the picking station 11 and is capable of transporting the object to be processed from the picking station 11 to the working station 31 on the lifting receiving platform 3; an image acquisition module 32 is disposed on the lifting receiving platform 3, the detection end of the image acquisition module 32 is disposed facing the picking station 11, and is used to capture an image of the object to be processed moving to the picking station 11; the positioning mechanism also includes a control device, which is connected to the image acquisition module 32 and the lifting and guiding assembly 2 respectively.

[0046] By installing a lifting and guiding component 2 below the material handling station 11, the object to be processed can be accurately transported from the material handling station 11 to the working station 31 on the lifting receiving platform 3. Its operation possesses high accuracy and stability, ensuring efficient material handling and effectively avoiding time waste and damage to the object due to inaccurate positioning. Simultaneously, an image acquisition module 32 is installed on the lifting receiving platform 3, with its detection end facing the material handling station 11. This module can capture images of the object moving to the material handling station 11, thereby obtaining detailed information such as the object's position, posture, and appearance. This information provides accurate data support for the operation of the lifting and guiding component 2, thus achieving precise positioning.

[0047] Furthermore, traditional mechanical positioning methods are often ineffective for products with non-linear outer contours. However, the positioning mechanism provided by this invention addresses this challenge by installing a lifting and guiding component 2 below the material handling station 11 and an image acquisition module 32 on the lifting receiving platform 3. The image acquisition module 32 can comprehensively and accurately capture images of products with non-linear outer contours at the material handling station 11, obtaining their unique position, posture, and appearance information. Based on this detailed information, the lifting and guiding component 2 precisely transports such products from the material handling station 11 to the work station 31 with high accuracy and stability, thus providing a reliable solution for processing products with non-linear outer contours. Simultaneously, the positioning mechanism provided by this invention has good compatibility with objects of different sizes. Regardless of the size of the object, the image acquisition module 32 can flexibly adjust the shooting angle and parameters to obtain accurate image information. The lifting and guiding component 2 can adaptively adjust according to the image information, ensuring accurate transport of objects of different sizes to the work station 31. This compatibility enables the positioning mechanism to adapt to the production needs of various products, improving its versatility and practicality, and resulting in good economic benefits.

[0048] The objects to be processed can be items to be inspected or products to be assembled, etc., and this utility model does not limit this. For example, the objects to be processed are various components of smartphones and smart wearable products, such as CG glass, mobile phone frames, mobile phone back covers, watch glass, and watch back covers. These different types of objects can be efficiently processed by the positioning mechanism provided by this utility model to meet different production needs. Whether it is the precise positioning of smartphone components for subsequent inspection or assembly operations, or the accurate handling and processing of smart wearable product components, this positioning mechanism plays an important role.

[0049] The roller conveyor assembly 1 is the conveying part of the positioning mechanism, having at least two conveying channels. It can simultaneously convey multiple objects to be processed, increasing the throughput and significantly improving overall conveying efficiency. Compared to a single-channel conveying method, it can quickly transport a large number of objects to be processed to the picking station 11, reducing waiting time and conveying cycle. It is understood that each conveying channel can operate independently or be coordinated and controlled according to production needs; this invention does not limit this.

[0050] The material handling station 11 can be the end of the conveying channel. When the object to be processed moves to the material handling station 11, it marks the end of the conveying process of the object on the conveying channel. In practical applications, the object to be processed enters the conveying channel from the starting end, and after a certain conveying time and distance, it finally reaches the tail end of the conveying channel, that is, the end of the conveying channel, ready for subsequent processing.

[0051] Below the material handling station 11, a lifting and guiding component 2 is installed. The lifting and guiding component 2 is the transfer part of the positioning mechanism and is used to undertake the handling task. It can be understood that by setting the lifting and guiding component 2 below the material handling station 11, the object to be processed upon arrival at the material handling station 11 can be operated without affecting the normal conveying of the roller conveyor assembly 1.

[0052] Specifically, in practical applications, after the object to be processed moves to the material handling station 11, the lifting and guiding component 2 will lift the object. Next, the lifting and guiding component 2 will adjust the position and / or posture of the lifted object to bring it to a suitable state. Finally, the lifting and guiding component 2 will precisely move the adjusted object to the work station 31, preparing it for subsequent processing.

[0053] When the object to be processed is an item to be inspected, workstation 31 is a specific inspection area for the item, which may be equipped with specific inspection instruments, tools, or fixing devices to ensure that the item to be inspected can be stably inspected at this position. When the object to be processed is a product to be assembled, workstation 31 is an assembly platform for the product to be assembled. This assembly platform may be equipped with various assembly tools, fixtures, and auxiliary equipment to meet the assembly needs of different types of products.

[0054] In this embodiment, the work station 31 is located on the lifting receiving platform 3. Firstly, the lifting receiving platform 3 serves as the operating platform for the positioning mechanism. Throughout the positioning process, the lifting receiving platform 3 receives the objects to be processed, transported by the lifting and guiding assembly 2, providing a stable workspace for subsequent inspection or assembly operations. Its lifting function allows for height adjustment based on different objects and operational requirements, better adapting to various work scenarios and facilitating cooperation with other equipment, thus improving the flexibility and versatility of the positioning mechanism. Secondly, the lifting receiving platform 3 also serves as an auxiliary part for information acquisition. The image acquisition module 32 installed on the lifting receiving platform 3, with its detection end facing the material handling station 11, can capture images of the objects to be processed as they move to the material handling station 11, providing accurate data support for the precise operation of the lifting and guiding assembly 2. By acquiring detailed information such as the position, posture, and appearance of the objects to be processed, the accuracy and reliability of the positioning mechanism are improved, ensuring that the objects can be accurately transported to the work station 31 for subsequent processing.

[0055] Specifically, the image acquisition module 32 can be a camera or other image sensor, and is used to capture images of the object to be processed as it moves to the material handling station 11. Through image acquisition, detailed information such as the position, posture, and appearance of the object to be processed can be obtained, providing accurate data for subsequent processing.

[0056] The positioning mechanism also includes a control device, which can be a microprocessor, a programmable logic controller (PLC), or an industrial computer. The control device is connected to the image acquisition module 32 and the lifting guide positioning component 2, respectively, to control the image acquisition module 32 and the lifting guide positioning component 2.

[0057] Specifically, the control module receives image data from the image acquisition module 32 and issues commands based on this data to control the movement of the lifting and guiding component 2. If a deviation in the position of the object to be processed on the conveyor channel is detected, such as the material being positioned to the left, the control device will immediately issue a corresponding command to move the lifting and guiding component 2 a certain distance to the left, so as to accurately transport the object to be processed to the correct position. Similarly, if the orientation of the object to be processed is not as expected, i.e., the angle is deviated, the control device will calculate the angle that needs to be adjusted based on the image data and issue a command to rotate and adjust the lifting and guiding component 2 to ensure that the object to be processed is transported to the working station 31 on the lifting receiving platform 3 in the correct posture. It can be understood that through the close cooperation between the control device, the image acquisition module 32, and the lifting and guiding component 2, the positioning mechanism can achieve precise adjustment and transportation of the object to be processed in different states, improving the accuracy, adaptability, and reliability of the positioning mechanism, and providing strong support for subsequent inspection or assembly operations. At the same time, setting up a control device can significantly improve the automation level of the positioning mechanism and minimize manual intervention. This effectively reduces errors and mistakes caused by human factors. Furthermore, the control device ensures a high degree of consistency in the positioning and handling of each object, thus strongly guaranteeing the quality stability of subsequent processing steps.

[0058] In some possible implementations of this utility model, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the positioning mechanism further includes: a feeding assembly 4, which is disposed upstream of the roller conveyor assembly 1 along the conveying direction, for conveying the object to be processed to any one of the at least two conveying channels of the roller conveyor assembly 1; the feeding assembly 4 includes a first driving part 41, a first connecting part 42, a first transmission shaft 43 and a guide roller 44, the first driving part 41 is connected to the first transmission shaft 43 through the first connecting part 42, and the first transmission shaft 43 is also connected to the guide roller 44, the first driving part 41 is used to drive the first connecting part 42 to move, so as to drive the guide roller 44 to rotate through the first transmission shaft 43; at least two guide plates 45 are disposed opposite each other above the guide roller 44 along the axial direction of the guide roller 44, the at least two guide plates 45 are used to limit the object to be processed in the axial direction of the guide roller 44.

[0059] By setting up the feeding component 4, the object to be processed can be continuously transported to any one of the conveying channels of the roller conveyor component 1, ensuring a stable material supply at the front end of the entire positioning mechanism, avoiding production interruption due to untimely material supply, and improving production efficiency.

[0060] The conveying direction can be the direction in which the object to be processed is conveyed and moved in the positioning mechanism.

[0061] The feeding component 4 is located upstream of the roller conveyor component 1 along the conveying direction, ensuring that the object to be processed can smoothly enter the subsequent roller conveyor and positioning process from the feeding stage.

[0062] Specifically, starting from the feeding assembly 4, the object to be processed is conveyed along the direction toward the roller conveyor assembly 1 under the action of the first drive unit 41, the first connecting unit 42, the first transmission shaft 43 and the guide roller 44.

[0063] The first drive unit 41 serves as a power source, providing power for the entire feeding process. In this embodiment, the first drive unit 41 transmits power through the first connecting part 42.

[0064] The first connecting part 42 serves to connect the first driving part 41 and the first transmission shaft 43. In this embodiment, the first connecting part 42 can effectively transmit the power generated by the first driving part 41 to the first transmission shaft 43, ensuring stable and efficient power transmission.

[0065] The first drive shaft 43 is a key component for power transmission. In this embodiment, the first drive shaft 43 receives power from the first connecting part 42 and is connected to the guide roller 44 to transmit power to the guide roller 44, enabling the guide roller 44 to rotate.

[0066] In this embodiment, the guide roller 44 plays a role in conveying the object to be processed during the feeding process. When the first drive shaft 43 drives the guide roller 44 to rotate, the object to be processed placed on the guide roller 44 will move forward with the rotation of the guide roller 44, and advance towards the conveying flow channel of the roller conveyor assembly 1.

[0067] Specifically, the first drive unit 41 can be a motor, the first connecting part 42 can be a belt 133 transmission assembly, the first transmission shaft 43 can be a rotating shaft, and the guide roller 44 can be a roller. In practical applications, several guide rollers 44 are provided, arranged sequentially along the conveying direction. Magnetic wheels are fitted at both ends of each guide roller 44. Simultaneously, two rotating shafts are provided, located on both sides of the guide roller 44 along the axial direction, and connected to two first drive units 41 via two first connecting parts 42. Magnetic wheels are also provided on the two rotating shafts. When the positioning mechanism starts operating, the motor, serving as the first drive unit 41, is activated. The motor transmits power to the two rotating shafts via the belt 133 transmission assembly (first connecting part 42). Since the two rotating shafts are located on both sides of the guide roller 44 along the axial direction and are connected to the motor, they begin to rotate after receiving power. The magnetic wheels on the rotating shafts attract each other and generate force with the magnetic wheels at both ends of the guide roller 44. As the rotating shaft rotates, the guide rollers 44 are driven to rotate by magnetic force. Several guide rollers 44 are arranged sequentially along the conveying direction. Under the synchronous action of the magnetic wheels at both ends, each guide roller 44 rotates at the same speed and direction. When the object to be processed is placed on the guide rollers 44, under the action of the rotation of the guide rollers 44, due to the existence of friction, the object to be processed passes through each guide roller 44 sequentially along the conveying direction, continuously moving towards the conveying flow channel of the roller conveyor assembly 1. In this process, two motors provide stable power to the two rotating shafts respectively through the belt transmission assembly 133. The magnetic wheels between the rotating shafts and the guide rollers 44 ensure the high efficiency and accuracy of power transmission, enabling the object to be processed to smoothly and quickly enter the subsequent stage of the positioning mechanism.

[0068] The material handling mechanism also includes a first mounting plate. Two first mounting plates are provided, and the two first mounting plates are arranged opposite each other at both ends of the guide roller 44 along the axial direction of the guide roller 44.

[0069] Specifically, both first mounting plates extend along the conveying direction, and several guide rollers 44 are rotatably mounted on the two first mounting plates. Understandably, the first mounting plates provide robust support for the guide rollers 44, allowing them to rotate smoothly without wobbling or shifting. Simultaneously, the extension of the first mounting plates along the conveying direction provides sufficient space for the sequential arrangement of the guide rollers 44, enabling the object to be processed to move smoothly along the conveying direction under the drive of the guide rollers 44. In actual operation, when the motor transmits power to the rotating shaft via the belt 133 transmission assembly, and the rotating shaft then drives the guide rollers 44 to rotate via the magnetic wheel, the two first mounting plates effectively withstand the various forces generated by the rotation of the guide rollers 44, ensuring the stability of the entire feeding process.

[0070] Among them, two guide plates 45 are movably provided on the two first mounting plates, and two guide plates 45 are provided and are arranged opposite each other along the axial direction of the guide roller 44.

[0071] Specifically, support plates are respectively provided on the two first mounting plates, which serve to support and connect other components. A fixing plate is provided between the two support plates, providing a stable mounting platform for the components below. A mounting block is slidably provided below the fixing plate, allowing the mounting block to be adjusted in position according to actual needs. Two guide plates 45 are fixed below the mounting block, which are arranged opposite each other along the axial direction of the guide roller 44. These guide plates 45 can limit the object to be processed in the axial direction of the guide roller 44, ensuring that the object to be processed maintains the correct position and orientation during the conveying process. It can be understood that by setting the guide plates 45, the position of the object to be processed can be initially corrected, so that the object to be processed entering the conveying channel is in the middle of the conveying channel, ensuring that the object to be processed is in the correct position after moving to the picking station 11, thus improving positioning accuracy. At the same time, since the object to be processed is in the middle of the conveying channel, it can maintain a relatively uniform distance from all parts of the conveying channel, making it less likely to collide or rub against the channel wall during the transmission process, thereby greatly reducing the possibility of jamming and blockage.

[0072] A transition roller can be installed between the feeding assembly 4 and the roller conveyor assembly 1 to connect them. When the object to be processed is conveyed from the guide roller 44 of the feeding assembly 4, the transition roller can smoothly receive the object and transfer it smoothly onto the conveying channel of the roller conveyor assembly 1. Understandably, by setting up the transition roller, the entire conveying process is made smoother, reducing jamming or stagnation caused by poor connection between the feeding assembly 4 and the roller conveyor assembly 1.

[0073] In some possible implementations of this utility model, see [link to relevant documentation]. Figure 1 and Figure 5 As shown, the positioning mechanism further includes: an infeed diversion component 5, which is movably disposed above at least two conveying channels for distributing the object to be processed on one conveying channel to the other conveying channel; the infeed diversion component 5 includes a first linear module 51, a second linear module 52, and a first suction cup 53, the first linear module 51 extending in a direction perpendicular to the conveying channel, the second linear module 52 extending in the axial direction of the conveying roller 15, the first suction cup 53 being connected to the first linear module 51, the first linear module 51 being disposed on the second linear module 52, and the second linear module 52 being used to cooperate with the first linear module 51 so that the first suction cup 53 can move below the object to be processed to adsorb the lower surface of the object to be processed.

[0074] By movably installing the feed diversion component 5 above at least two conveying channels, the objects to be processed on one conveying channel can be flexibly allocated to another conveying channel according to actual needs, realizing the diversion operation from single-channel feeding to dual-channel feeding. Specifically, when the objects to be processed are conveyed on one conveying channel, the feed diversion component 5 can transfer some or all of the objects to be processed to another conveying channel in a timely manner according to factors such as production plan, equipment status, or process requirements. Such diversion operation can make full use of the advantages of at least two conveying channels, improve the efficiency of subsequent inspection or assembly, and promote the smooth progress of subsequent inspection and assembly stages. For example, in the inspection stage, the objects to be processed can be allocated to different inspection channels to perform multiple inspections simultaneously, shortening the inspection time; in the assembly stage, the objects to be processed can be diverted to the corresponding channels according to different assembly processes, improving the coordination and efficiency of assembly.

[0075] The conveying channel is also equipped with a diversion station 17, which is located at the beginning of the conveying channel. In this embodiment, the feed diversion component 5 is used to distribute the object to be processed at the diversion station 17 on one conveying channel to the diversion station 17 on another conveying channel.

[0076] The feed diversion assembly 5 includes a first linear module 51 and a second linear module 52. The first linear module 51 and the second linear module 52 are mechanical structures that can realize linear motion. Specifically, they are composed of components such as guide rails, sliders, drive motors, and transmission mechanisms. They can convert rotational motion into linear motion, or achieve high-precision linear displacement directly through linear motors or other means.

[0077] The first linear module 51 extends in a direction perpendicular to the conveying channel, enabling precise movement in this direction and driving the connected first suction cup 53 to move up and down, allowing the first suction cup 53 to move below the conveying channel, thus preparing in advance for adsorbing the object to be processed.

[0078] The second linear module 52 extends along the axial direction of the conveyor roller 15, providing a basic moving track for the first linear module 51, so that the first linear module 51 can be positioned in the axial direction of the conveyor roller 15, ensuring that the first suction cup 53 can be accurately moved directly below the object to be processed.

[0079] Specifically, in practical applications, when it is necessary to allocate an object to be processed from one conveyor channel to another, the operation process is as follows: First, the second linear module 52 is controlled to move the first linear module 51 to a suitable position in the axial direction of the conveyor roller 15. Next, the first linear module 51 is controlled to drive the first suction cup 53 downward until the first suction cup 53 reaches the bottom of the conveyor channel. Then, the second linear module 52 is controlled again to move the first suction cup 53 precisely to the position directly below the object to be processed, at which point the first suction cup 53 adsorbs the lower surface of the object. Subsequently, the first linear module 51 drives the first suction cup 53 upward a certain distance, and then the second linear module 52 moves again, moving the first suction cup 53, which is adsorbing the object, to the top of the target conveyor channel. Finally, the first linear module 51 moves downward, and the first suction cup 53 releases the object, thus completing the diversion operation of the object.

[0080] In this invention, two adjacent conveyor rollers 15 at the material pick-up station 11 in the conveying channel are spaced apart to allow the first suction cup 53 to smoothly reach the bottom of the conveying channel and ultimately move precisely to the position directly below the object to be processed. It is understandable that traditional diversion methods may be difficult to implement for objects whose upper surfaces cannot be contacted. However, this invention, by setting adjacent conveyor rollers 15 at a certain distance at the material pick-up station 11 in the conveying channel, makes it possible for the first suction cup 53 to pick up the object from below, achieving flexible diversion operations and greatly improving the scheduling capability of the objects to be processed.

[0081] To ensure the suction nozzle of the first suction cup 53 faces upwards and can effectively adsorb the lower surface of the object to be processed, the mounting plate of the first suction cup 53 can be L-shaped. The L-shaped mounting plate is slidably mounted on the first linear module 51, allowing it to slide smoothly and precisely adjust the position of the first suction cup 53 perpendicular to the conveying channel as needed. When adsorbing an object, the L-shaped mounting plate can quickly move below the conveying channel under the drive of the first linear module 51, ensuring the suction nozzle of the first suction cup 53 is accurately aligned with the lower surface of the object, achieving stable and reliable adsorption operation.

[0082] In some possible implementations of this utility model, see [link to relevant documentation]. Figure 2 As shown, the roller conveyor assembly 1 includes a second drive unit 12, a second connecting part 13, a second transmission shaft 14, and a conveying roller 15. The second drive unit 12 is connected to the second transmission shaft 14 through the second connecting part 13. The second transmission shaft 14 is also connected to the conveying roller 15. The second drive unit 12 is used to drive the second connecting part 13 to move, so as to drive the conveying roller 15 to rotate through the second transmission shaft 14.

[0083] The second drive unit 12 is the power source for the entire roller conveyor assembly 1. Specifically, the second drive unit 12 can be a device such as a motor that can provide rotational power to generate sufficient power to drive the operation of subsequent components. In this embodiment, the second drive unit 12 is connected to the second transmission shaft 14 via the second connecting part 13, ensuring that power can be stably transmitted from the second drive unit 12 to the second transmission shaft 14. The second transmission shaft 14 is then connected to the conveying roller 15, enabling the conveying roller 15 to obtain a continuous and reliable power source, thereby achieving efficient rotation and fast and smooth conveying of the objects to be processed.

[0084] The second connecting part 13 can be a coupling, belt 133 pulley or other transmission components, used to connect the second drive part 12 and the second transmission shaft 14, so as to transmit the power generated by the second drive part 12 to the second transmission shaft 14.

[0085] The second drive shaft 14 can be a component such as a rotating shaft. The second drive shaft 14 is used to receive power from the second connecting part 13 and transmit it to the conveying roller 15.

[0086] The conveyor roller 15 directly contacts the object to be processed and performs the conveying function. Driven by the second drive shaft 14, the conveyor roller 15 rotates, thereby pushing the object to be processed to move on the roller conveyor.

[0087] Specifically, in practical applications, after the second drive unit 12 is activated, it generates rotational power. This power is transmitted to the second drive shaft 14 via the second connecting part 13. After receiving the power, the second drive shaft 14 begins to rotate and further transmits the power to the conveyor roller 15 connected to it. The conveyor roller 15 rotates under the drive of the second drive shaft 14, thereby realizing the conveying of the object to be processed.

[0088] In the above embodiments, see Figure 2 As shown, the conveying roller 15 includes a plurality of first conveying rollers 151 and a plurality of second conveying rollers 152 arranged at intervals along the conveying direction, with the plurality of first conveying rollers 151 and the plurality of second conveying rollers 152 arranged alternately; at least two second drive shafts 14 are provided, at least two second drive shafts 14 rotate synchronously, and at least two second drive shafts 14 are respectively poweredly connected to the plurality of first conveying rollers 151 and the plurality of second conveying rollers 152; the second connecting part 13 includes a driving wheel 131, a driven wheel 132 and a belt 133, the driving wheel 131 is connected to the driving end of the second drive part 12, the driven wheel 132 is connected to any one of the at least two synchronously rotating second drive shafts 14, and the belt 133 is connected to the driving wheel 131 and the driven wheel 132 respectively.

[0089] By staggering the arrangement of several first conveyor rollers 151 and several second conveyor rollers 152, the contact points between the conveyor rollers 15 and the objects to be processed can be increased while still satisfying the requirements for diverting and picking up the objects. This results in smoother conveying of the objects, reducing swaying and deviation during the conveying process, and improving the accuracy and efficiency of the conveying. By setting at least two second drive shafts 14 to rotate synchronously and be poweredly connected to the first and second conveyor rollers 151 and 152 respectively, it can be ensured that each conveyor roller 15 receives uniform power, avoiding situations where some conveyor rollers 15 have insufficient or excessive power. This improves the consistency and stability of the entire conveying process.

[0090] In particular, the distance between the first conveyor roller 151 and the second conveyor roller 152 at the diversion station 17 and the picking station 11 on the conveying channel is greater than the distance between the conveyor rollers 15 in other areas. This provides sufficient operating space for the feed diversion component 5 and the lifting guide positioning component 2 during diversion and picking operations. Specifically, when the feed diversion component 5 performs diversion operations, the larger distance ensures that components such as the first suction cup 53 can move smoothly between the conveyor rollers 15, thereby accurately adsorbing the object to be processed and transferring it to the target conveying channel. At the picking station 11, the larger distance also facilitates the picking device to perform gripping or other operations, improving the convenience and accuracy of operation. At the same time, this differentiated spacing setting meets the special needs of specific stations without affecting the overall conveying stability, making the operation of the entire conveying channel more efficient and flexible.

[0091] In particular, the extension lengths of the first conveyor roller 151 and the second conveyor roller 152 at the diversion station 17 and the picking station 11 on the conveying channel are shorter than the extension lengths of the conveyor rollers 15 in other areas, which can reduce interference with the diversion and picking operations. During the diversion process, components such as the first suction cup 53 of the feed diversion assembly 5 need to perform precise movement and suction actions between the conveyor rollers 15. The shorter conveyor rollers 15 do not obstruct their operating path, making the diversion operation smoother and more efficient. At the picking station 11, the shorter conveyor rollers 15 also provide a wider operating space for the picking device, making it easier for it to quickly and accurately grab the objects to be processed.

[0092] Magnetic wheels are fitted onto both the first conveying roller 151 and the second conveying roller 152, and magnetic wheels are also fitted onto at least two synchronously rotating second drive shafts 14. In practical applications, when the at least two synchronously rotating second drive shafts 14 rotate, the magnetic wheels fitted onto the at least two synchronously rotating second drive shafts 14 drive the magnetic wheels on the first conveying roller 151 and the second conveying roller 152 to rotate synchronously through magnetic force, thereby realizing the operation of the first conveying roller 151 and the second conveying roller 152.

[0093] In this embodiment, at least two synchronously rotating second drive shafts 14 are positioned opposite each other on both sides of the conveying channel and extend along the conveying direction. In this embodiment, the at least two second drive shafts 14 achieve synchronous rotation via a belt 133, so that when the second drive unit 12 drives one second drive shaft 14 to rotate via the second connecting part 13, at least two second drive shafts 14 rotate synchronously. It is understood that by eliminating the need for two separate second drive units 12 to drive each drive shaft, equipment costs and installation space are saved. Simultaneously, the synchronous rotation of multiple drive shafts can be achieved with only one second drive unit 12, making the rotation of the conveying roller 15 more stable and reliable, ensuring that the object to be processed can move smoothly forward during conveying, and reducing the possibility of conveying jams or damage to the object to be processed due to inconsistent rotation speeds of different drive shafts.

[0094] The second connecting part 13 includes a driving pulley 131, a driven pulley 132, and a belt 133. The belt 133 has a buffering and vibration-absorbing function, which can reduce the impact and vibration during the transmission process and make the power transmission smoother. At the same time, the design of the driving pulley 131 and the driven pulley 132 can adjust the transmission ratio as needed to meet different conveying speed requirements.

[0095] Specifically, the drive wheel 131 is connected to the drive end of the second drive unit 12. The second drive unit 12 is typically a power device such as a motor, and the power generated by the second drive unit 12 is transmitted through the drive wheel 131. The drive wheel 131 rotates under the drive of the second drive unit 12, becoming the starting point of the entire power transmission system. The driven wheel 132 is connected to any one of at least two synchronously rotating second transmission shafts 14. The driven wheel 132 receives power from the drive wheel 131 and transmits it to the connected second transmission shaft 14. In this way, the driven wheel 132 transmits the power of the second drive unit 12 to the second transmission shaft 14, thereby driving the conveyor roller 15 to rotate. The belt 133 is connected to both the drive wheel 131 and the driven wheel 132. The belt 133 transmits power, transferring the rotational motion of the drive wheel 131 to the driven wheel 132. The belt 133 transmission has a certain degree of elasticity and buffering effect, which can reduce the impact and vibration during the transmission process, making the power transmission smoother. Meanwhile, the belt 133 drive also has the advantages of simple structure, low cost and convenient maintenance.

[0096] The roller conveyor assembly 1 also includes two second mounting plates, both of which extend along the conveying direction. The first conveying roller 151 and the second conveying roller 152 are rotatably mounted on the two second mounting plates. It should be noted that the function of the second mounting plates in the roller conveyor assembly 1 is similar to that of the first mounting plates in the feeding assembly 4, both providing support and mounting foundations for components such as rollers. Therefore, the function of the second mounting plates will not be described in detail here.

[0097] In some possible implementations of this utility model, see [link to relevant documentation]. Figure 2 As shown, the roller conveyor assembly 1 also includes a light source module 16, which is located near the material handling station 11 and is used to provide illumination when the image acquisition module 32 captures images of the object to be processed.

[0098] By setting the light source module 16, illumination can be provided to the object to be processed when the image acquisition module 32 is taking pictures of the object to be processed, so that the image acquisition module 32 can take clear and accurate pictures of the object to be processed, providing more accurate position, posture, appearance and other detailed information to the lifting guide positioning component 2, thereby ensuring that the lifting guide positioning component 2 can more accurately identify and locate the object to be processed based on this information, thereby improving the accuracy and success rate of material handling.

[0099] The light source module 16 can be an LED light strip, a ring light, a fluorescent light, a spotlight, etc., which can provide illumination to the object to be processed when the image acquisition module 32 captures the object to be processed. This utility model does not limit this.

[0100] Specifically, in this embodiment, the light source module 16 is disposed on the second mounting plate, and at least part of the projection of the light source module 16 on the conveying channel coincides with the material picking station 11.

[0101] In some possible implementations of this utility model, see [link to relevant documentation]. Figure 8 As shown, the lifting guide positioning assembly 2 includes a slide cylinder 21, a third linear module 22, a fourth linear module 23, and a second suction cup 24. The slide cylinder 21 extends in a direction perpendicular to the conveying channel, the third linear module 22 extends in the axial direction of the conveying roller 15, the fourth linear module 23 extends in the conveying direction, and the second suction cup 24 is connected to the slide cylinder 21. The slide cylinder 21 is mounted on the third linear module 22, and the third linear module 22 is mounted on the fourth linear module 23.

[0102] By setting the slide cylinder 21 to extend in a direction perpendicular to the conveying channel, vertical movement can be achieved, allowing the object to be processed to be lifted or lowered from the conveying roller 15. By setting the third linear module 22 to extend along the axial direction of the conveying roller 15 and the fourth linear module 23 to extend along the conveying direction, the second suction cup 24 can move precisely in two horizontal dimensions, thereby accurately moving the object to be processed to the work station 31, achieving precise positioning and operation. By connecting the second suction cup 24 to the slide cylinder 21, the object to be processed can be firmly adsorbed, providing a stable gripping force without damaging the surface of the object, ensuring that the object will not fall off or shake during movement.

[0103] Among them, the slide cylinder 21, the third linear module 22 and the fourth linear module 23 are all mechanical devices that can realize linear motion. They have the characteristics of rapid response and motion, and can complete the lifting and moving of the object to be processed in a short time, which helps to improve production efficiency and reduce production cycle.

[0104] The second suction cup 24 is connected to the slide cylinder 21, and the movement of the slide cylinder 21 can drive the second suction cup 24 to move together. When the slide cylinder 21 rises, the second suction cup 24 also rises, thereby lifting the object to be processed from the conveyor roller 15. When the slide cylinder 21 descends, the second suction cup 24 also descends, thereby dropping the object to be processed onto the working position 31 of the lifting and transplanting platform.

[0105] The slide cylinder 21 is mounted on the third linear module 22. The third linear module 22 can drive the slide cylinder 21 and the second suction cup 24 connected thereto to move in the axial direction of the conveying roller 15, thereby adjusting the position of the second suction cup 24 in the axial direction so as to better adsorb and transport the object to be processed.

[0106] The third linear module 22 is mounted on the fourth linear module 23. The fourth linear module 23 can drive the third linear module 22, the slide cylinder 21, and the second suction cup 24 to move together in the conveying direction, so that the entire lifting guide positioning assembly 2 can move back and forth in the conveying channel to transport the object to be processed from one position to another.

[0107] Specifically, in practical applications, when the object to be processed arrives at the material handling station 11, the slide cylinder 21 rises, and the second suction cup 24 picks up the object. Then, the third linear module 22 and the fourth linear module 23 adjust the horizontal position of the second suction cup 24 and the object to be processed as needed. Finally, the slide cylinder 21 descends, placing the object to be processed on the work station 31.

[0108] In the above embodiments, see Figure 8 As shown, the lifting guide positioning component 2 also includes a hollow rotary platform 25, a slide cylinder 21 is mounted on the hollow rotary platform 25, and the hollow rotary platform 25 is connected to the third linear module 22.

[0109] By setting up a hollow rotary platform 25, an additional degree of rotational freedom is added to the lifting guide positioning component 2, allowing the object to be processed to move and adjust its posture more flexibly in three-dimensional space, thus meeting the requirements for high-precision positioning.

[0110] The hollow rotary platform 25 is a mechanical device capable of rotating around a central axis. It has a hollow structure to facilitate the installation and connection of other components. In the lifting and guiding assembly 2, the hollow rotary platform 25 provides rotational freedom for the object to be processed.

[0111] Specifically, the slide cylinder 21 is mounted on the hollow rotary platform 25. In practical applications, the rotation of the hollow rotary platform 25 can drive the slide cylinder 21 to rotate as well, thereby changing the orientation of the slide cylinder 21 and its connected components (such as the second suction cup 24). For example, when it is necessary to operate the object to be processed at different angles, the hollow rotary platform 25 can rotate the slide cylinder 21, and the orientation of the object to be processed can be adjusted by the second suction cup 24.

[0112] In some possible implementations of this utility model, see [link to relevant documentation]. Figure 6 and Figure 7 As shown, the lifting receiving platform 3 includes a third drive unit 33, a third connecting part 34, an adjusting plate 35, and a platform 36. The third drive unit 33 is connected to the adjusting plate 35 through the third connecting part 34. The adjusting plate 35 is also connected to the platform 36. The third drive unit 33 is used to drive the third connecting part 34 to move, so as to drive the platform 36 to rise and fall through the adjusting plate 35. The platform 36 is provided with at least four working stations 31. Each of the at least four working stations 31 is provided with a receiving space 311, which is used to adsorb the end of the object to be processed through the lifting guide positioning component 2. A third suction cup 37 is provided at each of the four corners of the receiving space 311. A support block 38 is provided between two adjacent third suction cups 37 and in the area outside the projection of the receiving space 311.

[0113] By setting up the third drive unit 33 and the third connecting unit 34, the adjustment plate 35 can be precisely driven to raise and lower the platform 36, allowing the working station 31 on the platform 36 to be adjusted to a suitable height according to different production needs, facilitating operation in conjunction with other equipment (such as the lifting guide assembly 2). For example, when transferring materials with the lifting guide assembly 2, the platform 36 can be adjusted to a position matching the height of the second suction cup 24, ensuring that the object to be processed can be accurately placed on the working station 31. In addition, different production processes may require different working heights. The height adjustability of the lifting receiving platform 3 allows it to adapt to various process changes, improving the versatility and flexibility of the positioning mechanism.

[0114] The third drive unit 33 can be a motor, cylinder, etc., used to generate driving force to realize the lifting and lowering movement of the platform 36.

[0115] One end of the third connecting part 34 is connected to the third driving part 33, and the other end is connected to the adjusting plate 35. It is used to transmit the power generated by the third driving part 33 to the adjusting plate 35, thereby driving the platform 36 to rise and fall.

[0116] The adjustment plate 35 is located between the third drive unit 33 and the platform 36, and is used to receive the power transmitted by the third connecting unit 34 and convert it into the lifting and lowering motion of the platform 36. In addition, the adjustment plate 35 can also adjust the position and angle of the platform 36 to ensure the coordination accuracy of the platform 36 with other equipment.

[0117] The platform 36 is equipped with at least four workstations 31 for carrying objects to be processed.

[0118] Specifically, see Figure 6 and Figure 7 As shown, at least four workstations 31 are each equipped with a receiving space 311 for receiving objects to be processed. In some specific examples, the positioning mechanism works as follows: First, the lifting and guiding component 2 lifts the object to be processed, which has been moved to the picking station 11, to a position at the same height as the workstation 31; then, the lifting and guiding component 2 controls the object to be processed to be translated to the workstation 31; finally, the positioning and guiding component releases the object to be processed, fixing it in the workstation 31. In other specific examples, first, the lifting and transferring platform component controls the workstation 31 on the platform 36 to be at the same height as the picking station 11; then, the lifting and guiding component 2 attracts the object to be processed, which has been moved to the picking station 11, and translates it to the workstation 31; finally, the positioning and guiding component releases the object to be processed, fixing it in the workstation 31. It should be noted that in this embodiment, since the work station 31 is provided with a receiving space 311, the space below the object to be processed placed at the work station 31 is open. Therefore, during the subsequent transfer of the object to be processed, the lower surface of the object can still be suctioned for operation. This makes it possible for the suction cup to suction the object from below, realizing flexible diversion operations and greatly improving the scheduling capability of the objects to be processed.

[0119] The receiving space 311 has a third suction cup 37 at each of its four corners. The third suction cup 37 is used to adsorb the lower surface of the object to be processed, so as to ensure the stability of the object on the work station 31. It can be understood that the third suction cup 37 can adsorb the object to be processed through vacuum adsorption, electromagnetic adsorption, or other methods.

[0120] A support block 38 is provided in the area between two adjacent third suction cups 37 and outside the projection of the receiving space 311. The support block 38 is used to provide additional support for the object to be processed, so as to enhance the stability of the object to be processed on the work station 31. It can be understood that the height and position of the support block 38 can be adjusted according to the size and shape of the object to be processed, so as to ensure that the object to be processed can be placed stably on the work station 31.

[0121] In the above embodiments, see Figure 6 As shown, the third connecting part 34 includes a ball screw 341, a screw fixing seat 342, a screw stop 343, and a locking nut 344. The ball screw 341 extends in a direction perpendicular to the conveying channel. One end of the ball screw 341 is connected to the third driving part 33, and the other end is connected to the adjusting plate 35. The screw fixing seat 342 is sleeved on the ball screw 341 and fixed relative to the third driving part 33. The locking nut 344 and the screw stop 343 are respectively arranged on both sides of the screw fixing seat 342 along the axial direction of the ball screw 341.

[0122] Among them, the ball screw 341 is a mechanical component that can convert rotary motion into linear motion. In this embodiment, the ball screw 341 extends in a direction perpendicular to the conveying channel, and can convert the rotary motion of the third drive unit 33 into precise linear motion to realize the lifting motion of the adjustment plate 35 and the platform 36.

[0123] The lead screw fixing seat 342 is sleeved on the ball screw 341 and fixed relative to the third drive part 33, which plays the role of fixing the ball screw 341, ensuring that the ball screw 341 will not shake or deviate during the movement, thus ensuring the accuracy and reliability of the movement.

[0124] The locking nut 344 and the lead screw stop 343 are respectively disposed on both sides of the lead screw fixing seat 342 along the axial direction of the ball screw 341. The locking nut 344 has a locking function, which can prevent the ball screw 341 from loosening during operation, thereby improving the stability and safety of the entire connection. The lead screw stop 343 has a limiting function, which can restrict the movement of the adjusting plate 35, ensuring that the adjusting plate 35 does not exceed the predetermined stroke range during movement.

[0125] The lifting transplanting platform assembly also includes a frame, with the third drive unit 33, the third connecting unit 34, the adjustment plate 35, and the platform 36 located on the same side of the frame.

[0126] Specifically, the third drive unit 33 is fixedly mounted on the frame, and drives the ball screw 341 connected to it through its output power. The screw fixing seat 342 is also fixed on the frame, ensuring that the ball screw 341 fitted therein remains stable during movement and does not wobble or shift. The screw stop 343 and the locking nut 344 also rely on the structure of the frame, located on both sides of the screw fixing seat 342 in the axial direction of the ball screw 341, respectively, playing their respective locking and limiting functions. The adjusting plate 35 moves up and down under the drive of the ball screw 341, and its movement trajectory is also constrained and guided by the frame, ensuring that the adjusting plate 35 and the connected platform 36 can accurately perform lifting and lowering operations within a predetermined range. The platform 36 is indirectly connected to the frame through the adjusting plate 35 and the ball screw 341 and other components. During the entire operation of the lifting and transplanting platform assembly, the frame always provides a stable and reliable support environment for the lifting and lowering of the platform 36, ensuring the normal operation of the lifting and transplanting platform assembly.

[0127] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0128] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above are only preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
