Description

Technical Field

[0001] This utility model relates to the field of automated training and teaching equipment technology, and more specifically, to a circular product connecting rod material distribution device. Background Technology

[0002] In automated production lines, especially in the processing, assembly, or inspection of round products, it is often necessary to orderly sort incoming materials, accurately pick them up, and precisely transfer them to their designated positions. For example, in scenarios such as bottle cap marking and round workpiece assembly, it is necessary to separate the disordered or continuously transported round products one by one and transfer them stably to the next workstation.

[0003] Existing solutions often fall short in achieving precise product separation and positioning with simple conveyor systems. While some complex robotic systems offer powerful functionality, their high cost and intricate structure may render them overly redundant for certain scenarios. Some material handling devices rely on gravity or simple mechanical obstructions, making it difficult to precisely control the timing of individual product release and pickup, and they exhibit poor adaptability to product size and conveyor speed. Furthermore, efficiently and stably performing the picking, moving, and placing of products from the conveyor belt to the fixed workstation, while ensuring placement accuracy, is also a problem that needs to be addressed.

[0004] Therefore, the market needs a device with a relatively simple structure, controllable cost, and capable of automating, efficiently and precisely distributing and transferring round products to meet the needs of automated training and small and medium-sized production lines. Utility Model Content

[0005] The present invention provides a circular product connecting rod material distribution device for automated training and teaching, which can solve the above-mentioned problems.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0007] This utility model provides a circular product dispensing and transfer device, comprising:

[0008] Product conveyor belt, used to transport the products;

[0009] The first vacuum suction cup, with the suction port facing upward, is set at a product fixing station to hold and position the product.

[0010] Product transfer components include:

[0011] The second vacuum suction cup, with its suction nozzle facing downwards, is used to pick up the product from the product conveyor belt.

[0012] The first pneumatic actuator is connected to the second vacuum suction cup and is used to drive the second vacuum suction cup to reciprocate in the up and down direction to pick up or place the product.

[0013] The second pneumatic actuator carries the first pneumatic actuator and the second vacuum suction cup, and drives the whole to reciprocate in the left and right direction, so that the second vacuum suction cup can move between the product pick-up position on the product conveyor belt and the product placement position of the first vacuum suction cup.

[0014] A pneumatic dispensing mechanism is disposed on one side of the product conveyor belt and located upstream of the product pick-up position. It is used to selectively block or release products on the conveyor belt to control the products to arrive at the pick-up position one by one.

[0015] Specifically, the product conveyor belt is equipped with at least one active drive roller and at least one driven roller, the surfaces of the active drive roller and the driven roller are fitted to the inner side of the product conveyor belt; the active drive roller and the driven roller are rotatably mounted on the base frame, and the active drive roller is connected to a speed-regulating motor through a transmission mechanism.

[0016] Specifically, the pneumatic dispensing mechanism includes:

[0017] Columns;

[0018] The material dispensing cylinder is installed on the column;

[0019] Support, installed on the base frame;

[0020] The dispensing execution frame has a drive end, a product blocking end, and a product toggle end. The dispensing execution frame is rotatably mounted on the support via a rotating shaft, which is perpendicular to the dispensing cylinder. The drive end of the dispensing execution frame is connected to the piston rod of the dispensing cylinder.

[0021] The material distribution cylinder drives the material distribution execution frame to rotate, so that its product-moving end can move the closest product on the product conveyor belt to the product pickup position, or its product-blocking end can block the closest product on the product conveyor belt.

[0022] Preferably, both the product actuation end and the product blocking end of the material distribution execution frame are provided with rollers, and the wheel surface of the rollers is used to contact the arc surface of the product.

[0023] Specifically, the first pneumatic actuator includes: a first linear slide plate on which the second vacuum suction cup is mounted; a first linear slide rail arranged in a vertical direction on which the first linear slide plate is slidably fitted; and a vertical drive cylinder arranged in a vertical direction on which its piston rod is connected to the first linear slide plate; the second pneumatic actuator includes: a second linear slide plate on which the first linear slide rail and the vertical drive cylinder are mounted; a picking cylinder arranged in a horizontal direction on which its piston rod is connected to the second linear slide plate; and a second linear slide rail arranged in a horizontal direction on which the second linear slide plate is slidably fitted; and a stand for mounting the second linear slide rail and the picking cylinder.

[0024] Preferably, the uprights, columns, and base frame are all mounted on a horizontally placed base plate.

[0025] Preferably, the first vacuum suction cup is mounted on the base plate by a support member; the first vacuum suction cup is provided with an upward-facing circular product limiting groove, and its suction port is located at the center of the circular product limiting groove; the product fixing station where the first vacuum suction cup is located is a product marking station; a laser marking machine is provided on one side of the first vacuum suction cup.

[0026] Compared with the prior art, the beneficial effects of this utility model are:

[0027] 1) Products are transported by a product conveyor belt. A pneumatic material distribution mechanism selectively blocks or releases incoming materials upstream of the product pickup position to ensure that products arrive at the pickup position one by one. Subsequently, the product transfer component, through the coordinated action of the second vacuum suction cup and the first and second pneumatic actuators, accurately picks up the products from the conveyor belt and transfers them stably to the station fixed by the first vacuum suction cup. The whole process is highly automated and significantly improves the efficiency of round product distribution and transfer.

[0028] 2) The product transfer assembly adopts a two-stage pneumatic actuator, realizing the reciprocating motion of the second vacuum suction cup in two different directions. This structure can flexibly adjust the posture and position of picking and placing, ensuring the accuracy of product picking and placing. The pneumatic dispensing mechanism adopts a dispensing execution frame connected to the dispensing cylinder and rotatable around the shaft. By switching between its product pushing end and product blocking end, it realizes reliable blocking and rapid dispensing of products. The dispensing action is crisp and clean, avoiding material jamming or leakage. The first vacuum suction cup is equipped with an upward-facing circular product limiting groove, which can perform secondary precise positioning of the transferred circular products, ensuring the product's stable posture at the fixed station, which is beneficial for subsequent processes such as marking.

[0029] 3) Rollers are installed on the product actuation end and the product blocking end of the pneumatic material dispensing mechanism. The rollers can be used to contact the arc surface of the round product, which can reduce contact friction.

[0030] 4) The device mainly uses pneumatic components as actuators, which have a fast response speed and are easy to control. Combined with PLC and other control systems, it can realize complex action logic and timing coordination. The product conveyor belt is driven by a speed-regulating motor, which can adjust the conveying speed according to the production cycle and product characteristics, increasing the flexibility and adaptability of the device. The overall structure is reasonably designed and the operation is stable and reliable.

[0031] 5) All major components, such as the uprights, columns, and base frame, are mounted on a unified base plate, making the overall structure compact and the layout reasonable. Compared with large robot systems, this device uses standard pneumatic components and a simple mechanical structure, resulting in lower manufacturing and maintenance costs. It is suitable for promotion and application in small and medium-sized production lines or for automation training and teaching.

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0040] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model discloses a circular product sorting and transfer device. The device is mainly installed on a horizontal base plate 17, realizing the automated sorting, picking, transfer and positioning of circular products 19 (such as bottle caps or other circular workpieces).

[0041] 1. Product conveying and distribution section:

[0042] Product conveyor belt 1 is arranged horizontally and is used to carry and transport products. For example... Figure 1 As shown, one end of the product conveyor belt is connected to the speed-regulating motor 4 through a transmission mechanism (for example, a gear transmission group, not shown in detail in the figure). The speed-regulating motor 4 can adjust the running speed of the conveyor belt according to the needs of the production cycle.

[0043] On one side of the product conveyor belt 1, a pneumatic material distribution mechanism is provided. This mechanism is used to form a controllable product picking window on the product conveyor belt 1, ensuring that only one product 19 stays at the predetermined picking position at a time, waiting to be transferred.

[0044] The pneumatic material distribution mechanism mainly includes a base frame 5 and a column 7 mounted on a base plate 17. The material distribution cylinder 6 (e.g., an Airtac brand cylinder) is mounted on the column 7.

[0045] Support 9 is installed on base frame 5. For example... Figure 4 As shown, the material dispensing execution frame 8 is rotatably mounted on the support 9 via a rotating shaft 20, and the axis of the rotating shaft 20 is perpendicular to the direction of movement of the piston rod of the material dispensing cylinder 6 (i.e., the cylinder axis).

[0046] The dispensing execution frame 8 has a coplanarly arranged drive end 81, product blocking end 82, and product actuating end 83. The drive end 81 is hinged to the piston rod end of the dispensing cylinder 6. Rollers 21 are preferably provided on both the product blocking end 82 and the product actuating end 83. The wheel surface of the roller 21 is used to contact the arc surface of the circular product 19, which can reduce friction and damage to the product during dispensing and ensure the integrity of the product surface.

[0047] During operation, when the piston rod of the dispensing cylinder 6 extends or retracts, it drives the dispensing execution frame 8 to swing around the rotating shaft 20 via the drive end 81. By precisely controlling the movement of the dispensing cylinder 6, the product blocking end 82 of the dispensing execution frame 8 can be rotated to directly above the working surface of the product conveyor belt 1, blocking the advancement of subsequent products 19; or, when it is necessary to release a product, the product blocking end 82 rotates to the side of the product conveyor belt 1, and at the same time, the product actuating end 83 can quickly and accurately move the foremost product 19 to the predetermined product pickup position. Before the product actuating end 83 resets, it also serves to block the next product 19 from continuing to move forward. After resetting, the product blocking end 82 blocks the product 19. This design can effectively achieve the separation of products one by one.

[0048] 2. Product Transfer and Positioning:

[0049] A product transfer assembly is installed above the product pickup position of the product conveyor belt 1 and above the product fixing position where the first vacuum suction cup 2 is located. The core of this assembly is the second vacuum suction cup 3, whose suction port faces downward, for picking up product 19 from the product conveyor belt 1.

[0050] To drive the second vacuum suction cup 3 to complete the picking and placing actions, the product transfer assembly is equipped with two sets of cooperating pneumatic actuators:

[0051] The first pneumatic actuator (achieving reciprocating motion) includes a vertical drive cylinder 11 with a fixed cylinder body and a piston rod whose free end is connected to a first linear slide plate 10. A second vacuum suction cup 3 is securely mounted on the first linear slide plate 10. The first linear slide plate 10 is slidably mounted on a first linear guide rail 12 arranged vertically. When the vertical drive cylinder 11 is activated, the second vacuum suction cup 3 moves vertically along the first linear slide plate 10 along the first linear guide rail 12.

[0052] The second pneumatic actuator (achieving reciprocating motion in the left-right direction) includes a picking cylinder 14, whose cylinder body is fixed on the upright frame 16, and the free end of the piston rod is connected to the second linear slide plate 13. The entire first pneumatic actuator (i.e., the up-down drive cylinder 11, the first linear slide plate 10, the first linear slide rail 12, and the second vacuum suction cup 3 fixed thereon) is mounted on the second linear slide plate 13 as a single unit. The second linear slide plate 13 is slidably mounted on the second linear slide rail 15 arranged horizontally. The second linear slide rail 15 and the picking cylinder 14 are both mounted on the upright frame 16, which is firmly mounted on the base plate 17. When the picking cylinder 14 is activated, the second linear slide plate 13, together with all the components it carries, moves horizontally along the second linear slide rail 15 between the picking position of the product conveyor belt 1 and the placement position of the first vacuum suction cup 2.

[0053] At the product fixing station, such as the product marking station in this embodiment, a first vacuum suction cup 2 is provided. The first vacuum suction cup 2 is mounted by a support member (which can be integrated into the base plate 17 or be a separate component), with its suction port facing upwards. To improve positioning accuracy, the upper surface of the first vacuum suction cup 2 is preferably provided with a circular product limiting groove that matches the shape of the circular product 19, and its suction port is located at the center of the limiting groove. When the product 19 is placed at this time, the limiting groove can play a role in auxiliary guidance and final positioning. In this embodiment, a laser marking machine 18 can be provided on one side of the first vacuum suction cup 2 for marking the product 19 held and positioned by the first vacuum suction cup 2.

[0054] 3. Workflow Example:

[0055] The automated operation of the entire device is centrally controlled by a PLC (Programmable Logic Controller, such as the Siemens 1200 series) based on preset programs and sensor signals. A typical workflow is as follows:

[0056] Product conveying and sorting: The speed-regulating motor 4 drives the product conveyor belt 1 to convey product 19. When the sensor detects that product 19 has arrived at the sorting area, the PLC controls the sorting cylinder 6 to act, so that the product blocking end 82 of the sorting execution frame 8 blocks the subsequent products, while ensuring that only one product 19 is currently at the product pick-up position below the second vacuum suction cup 3.

[0057] Product Pickup:

[0058] The PLC controls the piston rod of the up-and-down drive cylinder 11 to extend, causing the second vacuum suction cup 3 to descend rapidly until it contacts the product 19.

[0059] The vacuum system of the second vacuum suction cup 3 is activated, generating suction to hold the product 19.

[0060] The piston rod of the up-and-down drive cylinder 11 retracts, driving the second vacuum suction cup 3 and the adsorbed product 19 to rise to a safe height and detach from the product conveyor belt 1.

[0061] Product transfer: The PLC controls the piston rod of the picking cylinder 14 to move (e.g., extend), which drives the second linear slide plate 13 and the entire up-and-down motion unit and the second vacuum suction cup 3 (together with the product 19) to move horizontally along the second linear slide rail 15 until the second vacuum suction cup 3 is directly above the first vacuum suction cup 2.

[0062] Product placement and positioning:

[0063] The PLC controls the piston rod of the up-and-down drive cylinder 11 to extend again, gently placing the product 19 onto the first vacuum suction cup 2.

[0064] The vacuum system of the second vacuum suction cup 3 is shut off, releasing product 19. At the same time, the vacuum system of the first vacuum suction cup 2 is activated, generating suction to firmly hold and precisely position product 19.

[0065] The piston rod of the up-and-down drive cylinder 11 retracts.

[0066] Transfer component reset and preparation for the next cycle: The PLC controls the piston rod of the picking cylinder 14 to reverse (e.g., retract), causing the second vacuum suction cup 3 and the up-and-down motion unit to return to the initial pick-up preparation position above the product conveyor belt 1. At the same time, the PLC controls the dispensing cylinder 6 to release the next product 19 to the product pick-up position and prepare to block subsequent products 19.

[0067] Subsequent process: The product 19 positioned by the first vacuum suction cup 2 can be marked by the laser marking machine 18. After marking is completed, the product 19 can be manually removed.

[0068] Through the combination of the above structure and process, the circular product sorting and transfer device of this utility model can efficiently, stably and accurately complete the automated processing of circular products. It is suitable for automated training and teaching as well as small and medium-sized production lines with certain requirements for precision and efficiency.

[0069] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
