Description

Technical Field

[0001] This utility model relates to the field of automated production equipment technology, specifically a device for changing the quantity of products and picking up and placing products in sequence. Background Technology

[0002] In the field of automated production, product handling and transfer are crucial links connecting upstream and downstream processes. This is especially true when there are significant differences in batch quantity requirements between upstream and downstream processes, necessitating specific devices to achieve quantity conversion and maintain sequence. Current mainstream automated handling technologies typically rely on independent loading and unloading machines. The loading machine outputs a fixed number of products (e.g., 2 or 4 per batch) based on the upstream production rhythm, while the unloading machine receives a specific number of products (e.g., 4 or 5 per batch) according to the downstream process requirements. Because these machines target different processes, the magnitude of the input batch and output requirements often mismatches. For example, due to equipment processing efficiency limitations, the upstream process can only transport 4 molds with products per batch, while the downstream assembly process, to ensure continuous operation, needs to receive 5 molds per batch. This quantity difference necessitates additional manual intervention in the production process. Operators must arrange the products output from the loading machine in sequence before transferring them to the unloading machine. This not only increases labor costs but also severely restricts the overall production line efficiency due to low manual operation efficiency and long waiting times.

[0003] Furthermore, the manual arrangement of products can easily disrupt the original feeding sequence. In precision manufacturing, products are typically fed in order of their processing numbers to allow subsequent processes to trace the processing information (such as processing time and inspection data) of each product. If the order is disrupted during manual arrangement, the product traceability chain will be broken, making it impossible to accurately locate product batches with quality problems and increasing the difficulty of quality control. Meanwhile, although some existing automated transfer devices attempt to solve the quantity matching problem, they mostly rely on a large number of intermediate buffer structures to temporarily store products. This not only occupies a significant amount of production space but also makes it difficult to achieve real-time input and output conversion. When the production line rhythm is adjusted, the adaptability of the buffer structure is poor, unable to flexibly cope with different quantity multiplication requirements, and failing to meet the efficient, compact, and flexible operation requirements of modern production lines. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a device for changing the quantity of products and picking and placing products in sequence, thereby reducing manual intervention and improving production efficiency and product traceability accuracy.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An apparatus for changing the quantity of products and picking up and placing products in sequence includes:

[0007] The platform, which is rectangular in shape, serves as the core component supporting the device; a transfer area is provided on the upper surface of the platform.

[0008] The adjustment unit is configured with two units; the two adjustment units are arranged symmetrically at 180° with the center vertical line of the tabletop; the adjustment unit includes a horizontal adjustment component and a vertical adjustment component.

[0009] The lateral condition component moves the product group horizontally, and the longitudinal adjustment component pushes the products vertically in a quantitative manner.

[0010] Preferably, the lateral adjustment assembly includes a motor, a synchronous belt, a first toothed pulley, a second toothed pulley, a first guide rail, a first slider, a support plate, a first cylinder, a second guide rail, a second slider, and a first push plate; the motor is fixed to the bottom of the platform; the first toothed pulley is mounted on the output shaft of the motor; the second toothed pulley is rotatably mounted on the bottom of the platform; the first toothed pulley and the second toothed pulley are connected by a synchronous belt drive; the first guide rail is fixed to the upper part of the platform; the first slider is slidably mounted on the first guide rail; and one side of the first slider is fixed to the synchronous belt. Fixed connection; the support plate is fixed on the first slider; the first cylinder and the second guide rail are fixed on the support plate; the second slider is slidably mounted on the second guide rail; the piston rod of the first cylinder is fixedly connected to the second slider; the axis of the first cylinder is parallel to the length direction of the second guide rail; the first push plate is fixed on one side of the second slider; the first push plate and one side of the support plate are parallel and spaced apart; the longitudinal adjustment assembly includes a base, a second cylinder and a second push plate; the base is fixed to the upper end of the platform; the second cylinder is fixed on the base; the second push plate is fixed on the piston rod of the second cylinder.

[0011] Preferably, a material box is installed on the transfer area of ​​the table.

[0012] Preferably, the lateral adjustment assembly further includes a transmission plate; the upper end of the transmission plate is fixedly connected to the first slider, and the lower end is fixed to one side of the synchronous belt.

[0013] Preferably, the platform is provided with a guide hole, the guide hole is rectangular in shape, and the transmission plate is provided through the guide hole from the top of the platform downward.

[0014] Preferably, the axes of the first cylinder and the second cylinder are arranged parallel to each other; the first push plate and the second push plate are arranged perpendicular to each other.

[0015] Preferably, the piston rods of the first cylinder and the second cylinder are positioned toward the center of the platform.

[0016] Preferably, the lower end of the platform is fixedly provided with multiple support legs.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This device uses two symmetrically arranged adjustment units in conjunction with the transfer area on the table. The lateral adjustment component uses a motor-driven synchronous belt to stably move the molds on the support plate, allowing precise control over the transfer frequency and quantity of each batch. The longitudinal adjustment component uses a cylinder to push a pusher plate, orderly pushing the molds on the support plate to the transfer area for temporary storage until the number of molds in the transfer area reaches the output requirements of the downstream process. This allows for conversions of different orders of magnitude (e.g., 2→4, 4→5, etc.) without manual intervention. Compared to traditional devices that rely on manual arrangement or large buffers, this device, through its "lateral transfer + longitudinal transfer" structural design, achieves instant connection between input and output, significantly improving the efficiency of quantity conversion and adapting to upstream and downstream processes with different rhythms.

[0019] The first cylinder in the lateral adjustment assembly works in conjunction with the first push plate to align the mold position after material loading, ensuring that each batch of molds is arranged in the initial sequence. When the longitudinal adjustment assembly pushes the mold, the push plate acts on the mold along a fixed direction, preventing the mold from shifting position or becoming disordered during transfer. Simultaneously, the two adjustment units are symmetrically arranged, and both loading and unloading processes follow fixed paths, further ensuring the consistency of the product's sequence from upstream loading to downstream unloading. This structural design effectively avoids the sequence disorder caused by manual arrangement, providing a stable sequence foundation for full-process product traceability and improving the accuracy of quality control.

[0020] The device uses a rectangular platform as its core support, with the adjustment unit integrating lateral and longitudinal adjustment functions. It features a clean, non-complex structure and occupies minimal production space. The lateral adjustment component uses guide rails and sliders for smooth transmission and allows for adjustment of the support plate's travel according to mold dimensions. The longitudinal adjustment component's cylinder stroke can accommodate material boxes of varying depths in the transfer area. Furthermore, the two adjustment units are symmetrically arranged, allowing for switching between loading and unloading positions based on actual production needs, flexibly adapting to different production line layouts. This compact and flexible design makes it suitable for producing various types of products, including medium-sized parts and small electronic components, demonstrating strong versatility.

[0035] How to use

[0036] This device is based on the core logic of "lateral adjustment and transfer + longitudinal adjustment and transfer". Through the symmetrical arrangement of adjustment units and the transfer area, it realizes the multiplication of product quantity and orderly picking and placing. The specific operation process is as follows (prerequisite: the device has been installed and debugged, the support leg 9 is fixed and stable, and the motor 8, cylinder, synchronous belt 5 and other components are in normal working condition):

[0037] 1. Preparation stage

[0038] Component inspection and parameter setting:

[0039] Check whether the material box 13 in the transfer area of ​​the table 14 is securely installed (the capacity of the material box 13 must match the single-time demand of the downstream process), and clean the debris on the table 14 and the guide rails.

[0040] Based on the required quantity of material loading / unloading, set the parameters of the lateral adjustment component: set the motor speed of motor 8 (controlling the moving speed of the support plate 6, usually 1200-1800 rpm) and the transmission stroke of synchronous belt 5 (adapting to the distance between the support plate 6 and the transfer area) through the motor 8 controller; set the stroke of the first cylinder 2 (for lateral fine adjustment of the mold position) and the second cylinder 11 (for longitudinal pushing of the mold to the transfer area) through the cylinder pressure regulating valve (adapting to the mold size and the depth of the material box 13).

[0041] After confirming that there are no foreign objects in the guide hole 4, the transmission plate 7 can pass through smoothly, and the first slider and the second slider 16 slide on the guide rail without jamming.

[0042] Initial position calibration:

[0043] Activate the "reset" button on the left and right adjustment units. The motor 8 drives the synchronous belt 5 to rotate, causing the two bearing plates 6 to move to the initial loading position (150-200mm from the edge of the table 14, to accommodate the space for the robot to pick up and put down) and the initial unloading position (10-15mm from the transfer area, to facilitate receiving the mold in the transfer area).

[0044] 2. Feeding and Lateral Adjustment Stage

[0045] Mold loading:

[0046] The upstream robotic arm grabs the corresponding number of product molds (e.g., 4 molds per upstream loading) and places them on the support plate 6 of the left adjustment unit, ensuring that the edge of the mold is parallel to the side of the support plate 6.

[0047] Mold horizontal alignment:

[0048] Start the first cylinder 2 of the left horizontal adjustment component. The piston rod of the first cylinder 2 pushes the second slider 16 to slide along the second guide rail 1, which drives the first push plate 15 to move towards the mold and align the mold on the support plate 6 (the spacing is set according to the number of materials to be fed, such as 10mm between 4 molds to ensure no offset in subsequent pushing). After alignment, the first cylinder 2 is reset.

[0049] Carrier plate 6 is transferred to the transfer area:

[0050] Start the left motor 8. The output shaft of motor 8 drives the first toothed pulley 17 to rotate, and drives the second toothed pulley 18 to rotate synchronously through the synchronous belt 5. The synchronous belt 5 drives the first slider to slide along the first guide rail 3 through the transmission plate 7 (through the guide hole 4 of the table 14), thereby moving the bearing plate 6 to the corresponding position on the left side of the transfer area (1310mm away from the material box to avoid collision with the material box 13), and the motor 8 stops.

[0051] 3. Vertical adjustment and transit integration stage

[0052] The mold is pushed into the transfer area:

[0053] Start the second cylinder 11 of the left longitudinal adjustment component. The piston rod of the second cylinder 11 pushes the second push plate 12 to move towards the material box 13, and smoothly pushes all the molds (e.g., 4) on the support plate 6 into the material box 13 in the transfer area. After the push is completed, the second cylinder 11 is reset. At this time, the number of molds in the material box 13 is accumulated (e.g., 4 after the first push).

[0054] Feed material continuously until the unloading requirement is met:

[0055] The left support plate 6 is driven by the motor 8 to reset to the initial feeding position, and repeats the steps of "mold feeding → horizontal alignment → transfer to the transfer area → vertical push into the material box 13" until the number of molds in the material box 13 reaches the single demand of the downstream process (if the downstream needs 5, then 4 molds need to be fed in 2 times, and 8 molds accumulate in the material box 13, and the excess is used to connect the next batch).

[0056] 4. Material feeding and sequence maintenance stage

[0057] The mold is transferred to the unloading position:

[0058] Start the motor 8 of the right adjustment unit. The motor 8 drives the right bearing plate 6 to slide along the first guide rail 3 to the corresponding position on the right side of the transfer area (1310mm from the material box); start the right first cylinder 2 and adjust the position of the first push plate 15 to ensure that the mold can be received smoothly.

[0059] The mold is pushed longitudinally to the blanking support plate 6:

[0060] Start the second cylinder 11 of the right longitudinal adjustment component. The second push plate 12 pushes the first N molds arranged in the loading sequence in the material box 13 (if 5 are needed downstream, push the first 5, and leave the remaining 3 in the material box 13 to connect to the next batch), push them into the right support plate 6, and then the second cylinder 11 resets.

[0061] Material cutting completed:

[0062] The right motor 8 starts, driving the bearing plate 6 to slide along the first guide rail 3 to the downstream unloading position. The downstream robot grabs the mold in sequence (keeping the numbering order when loading for easy traceability). After the grabbing is completed, the right bearing plate 6 is reset, completing one cycle of "loading → multiple conversion → unloading".

[0066] Downstream processes: Each batch requires receiving 5 parts, and the order must be maintained as "1#→2#→3#→4#→5#" (5# is the first piece of the next batch) to avoid confusion in traceability;

[0067] Production line space: The dimensions of the tabletop installation area are ≥1500mm×1000mm, and the height is ≥1200mm (including the space for the robot arm).

[0078] Set the initial position of the left support plate (200mm from the left edge of the table) and the initial position of the right support plate (200mm from the right edge of the table); adjust the stroke of the first cylinder to 80mm (leaving a 10mm gap on each side of the four molds), and adjust the stroke of the second cylinder to 120mm (material box depth 120mm).

[0079] First loading and transfer:

[0082] Second loading and transfer integration:

[0083] The left support plate is reset, and the robot places four molds: "5#→6#→7#→8#". The alignment, transfer, and pushing steps are repeated until a total of eight molds (1#-8#, arranged in order) are accumulated in the material box.

[0084] Material feeding operation:

[0085] The right-side motor drives the support plate to move to the right side of the transfer area, and the second cylinder pushes the first 5 molds (1#-5#) in the material box into the right-side support plate;

[0086] The right-side motor drives the support plate to move to the downstream unloading position. The downstream robot arm removes the mold in the order of "1#→2#→3#→4#→5#", completing the 4→5 transformation.

[0087] Looping connection:

[0088] There are 3 molds (6#-8#) remaining in the material box. After the next batch of 4 molds (9#-12#) are added, there will be 7 molds in the material box. Then, 4 more molds (6#-9#) are pushed to make up the 5 molds downstream (6#-10#, and 1 more mold (10#) needs to be added), and the order is maintained.
