Description

Technical Field

[0001] This invention relates to the field of product pressure holding technology, and in particular to a product pressure holding system, method, computing device and medium. Background Technology

[0002] With the rapid development of intelligent new energy vehicles in China, automobiles have become the second largest carrier of intelligent innovation. In-vehicle displays are increasingly aligning with mobile phones (the first largest carrier), and narrow-bezel screens are becoming the trend. The traditional method of using VHB (Vacuum-Hydraulic Adhesive) to bond screens and structural components is becoming increasingly difficult. Narrower bezels lead to narrower VHB widths and reduced adhesion, resulting in quality issues such as screen surface defects and detachment. Dispensing adhesive has become the mainstream method due to its low cost and strong adhesion. Dispensing adhesive adds a pressure-holding process, applying pressure to the product to ensure a tight bond. This pressure-holding process is specifically designed for dispensing products and requires measurable components such as pressure blocks or servo pressure blocks to apply and maintain a certain force on the product, allowing the adhesive to bond.

[0003] Traditionally, for small-batch and mixed-line production, multiple automated pressure-holding lines and manual pressure-holding fixtures are established. This leads to a chaotic production line layout, low automation, and once the automated pressure-holding line is designed and debugged, the key process parameters for pressure holding—time and weight—are fixed. Automated pressure-holding lines work by automating the process: the product enters the line, a gripper places the pressure-holding block on the product, and the product travels at a fixed speed over a fixed distance, maintaining pressure for a fixed time. Once the automated line is built and debugged, the pressure-holding time is difficult to change. For multi-variety production with varying sizes and shapes, automated lines cannot be reused; multiple pressure-holding lines must be established.

[0004] However, designing a pressure-holding line for each product would increase production costs and subsequent maintenance costs. Summary of the Invention

[0005] To overcome the problem that designing a pressure holding line for each product would increase production costs and subsequent maintenance costs, this invention provides a product pressure holding system, method, computing device, and medium.

[0006] In a first aspect, in order to solve the above-mentioned technical problems, the present invention provides a product pressure holding system, including a pressure holding control system, a flexible handling system and a three-dimensional storage system, wherein the flexible handling system is connected to the pressure holding control system and the three-dimensional storage system respectively.

[0007] The pressure holding control system is used to determine the pressure holding weight and pressure holding time of each product based on the incoming material information of each product, and to place the pressure holding block of each pressure holding weight on the corresponding product.

[0008] The flexible handling system is used to generate handling routes for each product containing pressure-holding blocks, and to control AGVs to transport each product containing pressure-holding blocks to the three-dimensional storage system according to the handling routes.

[0009] A three-dimensional storage system is used to store the corresponding holding time for each product containing a holding block;

[0010] The flexible handling system is also used to move each product to the pressure holding control system after the pressure holding time has ended;

[0011] The pressure holding control system is also used to remove each pressure holding block from the corresponding product when the pressure holding time ends.

[0012] Secondly, the present invention also provides a product pressure holding method, comprising:

[0013] Based on the incoming material information of each product, determine the corresponding holding weight and holding time for each product, and place the holding block of each holding weight on the corresponding product.

[0014] Generate transport routes for each product containing pressure-holding blocks, and control the AGV to transport each product containing pressure-holding blocks to the three-dimensional storage system according to the transport routes;

[0015] Store the corresponding holding time for each product with a holding block placed on it;

[0016] Move each product to the pressure holding control system after the pressure holding time has ended;

[0017] Remove each pressure holding block from its corresponding product when the pressure holding time has ended.

[0018] Thirdly, the present invention also provides a computing device, including a memory, a processor, and a program stored in the memory and running on the processor, wherein the processor executes the program to implement the steps of the product pressure holding method described above.

[0019] Fourthly, the present invention also provides a computer-readable storage medium storing instructions that, when executed on a terminal device, cause the terminal device to perform the steps of a product pressure holding method.

[0020] The beneficial effects of this invention are as follows: Before holding each product under pressure, the corresponding holding weight and holding time for each product are determined, and a holding block with the corresponding holding weight is selected for each product to be held under pressure separately. After the holding time for each product reaches the corresponding holding time, the holding block is removed from the product. This allows products with different holding requirements to be held under pressure on a single holding line, improving the utilization rate of the holding line. Compared to designing a separate holding line for each product, this method reduces the number of holding lines, thereby reducing the production cost of the holding line and the subsequent maintenance cost of the holding line.

[0026] The following embodiments are further explanations and supplements to the present invention and do not constitute any limitation on the present invention.

[0027] The following description, in conjunction with the accompanying drawings, describes a product pressure holding system, method, computing device, and medium according to an embodiment of the present invention.

[0028] like Figure 1 As shown, the present invention provides a product pressure holding system, including a pressure holding control system, a flexible handling system, and a three-dimensional storage system, wherein the flexible handling system is connected to the pressure holding control system and the three-dimensional storage system respectively;

[0029] The pressure holding control system is used to determine the pressure holding weight and pressure holding time of each product based on the incoming material information of each product, and to place the pressure holding block of each pressure holding weight on the corresponding product.

[0030] The flexible handling system is used to generate handling routes for each product containing pressure-holding blocks, and to control AGVs to transport each product containing pressure-holding blocks to the three-dimensional storage system according to the handling routes.

[0031] A three-dimensional storage system is used to store the corresponding holding time for each product containing a holding block;

[0032] The flexible handling system is also used to move each product to the pressure holding control system after the pressure holding time has ended;

[0033] The pressure holding control system is also used to remove each pressure holding block from the corresponding product when the pressure holding time ends.

[0034] This embodiment of a product pressure-holding system determines the pressure-holding weight and duration for each product before pressure-holding. It then selects a pressure-holding block of the corresponding weight for each product and pressure-holds it separately. Once the required pressure-holding time is reached, the pressure-holding block is removed from the product. This allows for pressure-holding of products with different pressure-holding requirements on a single pressure-holding line, improving the line's utilization rate. Compared to designing a separate pressure-holding line for each product, this method reduces the number of pressure-holding lines, thereby lowering production and maintenance costs. Furthermore, by placing pressure-holding blocks of different weights onto the corresponding products in the pressure-holding control system, and then transporting the products with the blocks to an automated storage system using AGVs, the system increases the number of products that can be pressure-held simultaneously, thus improving the efficiency of pressure-holding multiple products. Furthermore, each product whose holding time in the three-dimensional storage system has ended is transported to the holding control system, and the holding block on the product is removed, so that the next corresponding product that has not yet been held can be held. This enables the automatic reuse of the holding blocks, improves the utilization rate of each holding block, and increases the degree of automation when using each holding block.

[0035] In some embodiments, the company's independently developed pressure-holding technology adopts a centralized warehousing concept, concentrating products of multiple varieties, small batches, and mixed production lines within a workshop into a single pressure-holding area. Multi-layer stacking improves space utilization. The pressure-holding control system, based on task type, urgency, and other requirements, controls the flexible handling system to generate routes while simultaneously making pick-and-place decisions. The pick-and-place system picks up pressure blocks of different weights, places them on the products, and then removes the products and pressure blocks, placing them into the flexible handling system. For example, a carrier can be used to place products and pressure blocks. The carrier can hold three types of products in three fixed positions, with three different weight pressure blocks placed on top of each product, also in fixed positions. The pressure blocks are placed on any one of the three types of products on the carrier based on the incoming product. The flexible handling system automatically generates routes through the pressure-holding control system and uses visual obstacle avoidance to transport the products to the appropriate locations. For example, the flexible material handling system pre-programs each route. During debugging, it traverses each location and then manually saves the data, storing it in the AGV (Automated Guided Vehicle) system. Each product has its own fixed storage location, and based on product information from the front end, it is placed into the corresponding storage location in the automated storage system. The automated storage system is responsible for partitioning and storing corresponding products. Centralized storage and pressure holding technology features a simple structural design and high reusability; one-click switching between mixed-line production without manual fixture changes; for example, the PLC electrical control design has four programs, each stored in the system. When a specific program is needed, it is manually selected; and the software configuration allows for easy modification of key process parameters. Centralized storage and pressure holding technology helps companies save space and cost waste associated with discrete and fixed pressure holding, achieving unmanned and intelligent operation of new production line processes.

[0036] The flexible material handling system (RDS) differs from traditional grid-based maps. In scenarios with arbitrary route structures and human interference, RDS employs the G-MAPF algorithm for dynamic global collaborative planning, performing multi-robot path searching and traffic control. This allows robots to effectively avoid congestion and prevent deadlocks. A safety protection device is composed of laser obstacle sensors (50Hz detection frequency, 0-360° detection range, adjustable detection distance 0-30m) to ensure operational safety. The system brakes to a stop when an obstacle is detected within 1 meter (distance adjustable). The overall system uses a three-stage detection mechanism: a warning, deceleration, and braking. When an obstacle enters the safety warning zone, the AGV decelerates and sounds an alarm; when an obstacle enters the danger zone, the AGV automatically stops and resumes operation automatically after the obstacle is removed.

[0037] The pressure-holding control system, based on the incoming material status of the front-end equipment used for product production, uses a PLC to calculate the material arrival time and signal feedback. For example, after the front-end equipment finishes processing the product, it flows to a designated location. Sensors at this location detect the product and send feedback to the PLC, which then issues instructions to each workstation. AGVs prioritize the functions that need to be completed at each workstation based on the PLC feedback. For instance, in an automated storage and retrieval system (AS / RS), if the product's pressure-holding time has expired and the AGV needs to retrieve it, but another product arrives at the front-end equipment, the AGV needs to transport the product with the corresponding pressure-holding weight to the AS / RS for storage. Prioritization can be based on feedback time from various sensors. For example, photosensitive sensors can be installed next to each carrier in the pressure-holding system. If a photosensitive sensor detects a dimming of light, it indicates that the carrier corresponding to that sensor has incoming material that needs pressure-holding processing. Similarly, pressure sensors can be installed in each carrier. If a pressure sensor detects a pressure value greater than a set pressure, it indicates that the carrier containing that pressure sensor has incoming material that needs pressure-holding processing. RDS is used to control the movement of AGVs (Automated Guided Vehicles), forklifts, and turning. An AGV is a type of automated forklift that can move autonomously. PLC is a programmable storage device that implements the movement of equipment, such as cylinders and motors.

[0038] The automated storage and retrieval system (AGV) places the pressure-holding carriers into the storage area. Based on the adhesive strength of the bonding agent or temperature, each carrier containing the product and pressure-holding block is placed in its corresponding storage area for the specified pressure-holding time. Each carrier needs to remain in the storage area for one hour. Once the storage area is full of 60 carriers, after the first carrier has been in place for one hour, the AGV places it into the rear of the pressure-holding control system. The system then retrieves the product. The AGV continuously places and retrieves carriers, allowing the pressure-holding control system to remove the pressure-holding block for the next product, thus creating a cycle.

[0039] In some embodiments, the holding time of the product is determined based on the viscosity of the adhesive used to bond the product, or the temperature, etc.

[0040] In some embodiments, the automated storage and retrieval system is divided into multiple storage areas, with one type of product stored in one storage area.

[0041] Optionally, the incoming material information is production process information, used in the pressure holding control system, specifically for:

[0042] Determine the corresponding product category using the manufacturing process information of each product;

[0043] The system retrieves the holding weight and holding time for each product category from a pre-set database. The pre-set database stores the correspondence between product categories and holding weights, as well as the correspondence between product categories and holding times.

[0044] In this embodiment, the holding weight and holding time of each product category are roughly the same. By presetting the holding weight and holding time of each product category and storing them in a preset database, it is convenient to directly call the corresponding holding weight and holding time from the preset database each time the product needs to be held under pressure, and automatically place the holding block of the corresponding holding weight on the corresponding product, and store the corresponding holding time, thereby improving automation efficiency.

[0045] Optionally, the flexible handling system is specifically used for:

[0046] Obtain the task type for each product containing the pressure-holding block;

[0047] The urgency level is determined based on the duration of pressure-holding block placement for each product;

[0048] Determine the handling routes for each product containing pressure blocks based on the task type and urgency of each product.

[0049] In this embodiment, since the production needs of each type of product are different during the production process, the corresponding task types and urgency levels also differ. Therefore, determining the transportation route for each product containing the pressure-holding block based on the task type and urgency level of each product can meet the production needs of various product types.

[0050] Optionally, the task type is task priority, flexible handling system, specifically used for:

[0051] Find the task priority corresponding to each product with a pressure holding block placed in the preset data table; the preset data table stores the correspondence between products and task priorities.

[0052] In this embodiment, because the production time and delivery time of each type of product are different, the task priority for handling each type of product containing pressure blocks is different. By storing the pre-set products and their corresponding task priorities in a preset data table, the task priority of each product can be directly invoked when needed, thereby improving the efficiency of generating handling routes.

[0053] Optionally, the flexible handling system is specifically used for:

[0054] For each product, the first duration corresponding to that product is determined by starting the timing when the pressure block with the corresponding pressure holding weight is placed on the product.

[0055] Sort the first durations in descending order to determine the emergency sequence of each product with pressure holding blocks.

[0056] Each emergency sequence is assigned as the level of urgency of the product containing the pressure-holding block.

[0057] In this embodiment, the longer the pressure-holding block corresponding to the pressure-holding weight is placed on the product, the more urgent it needs to be transported to the automated storage and retrieval system for storage. Therefore, the products are sorted in descending order of the first time since the pressure-holding block was placed, based on this sorting. This sorting allows for a more accurate determination of the urgency of each product with a pressure-holding block.

[0058] Optionally, the flexible handling system is specifically used for:

[0059] For each product, the sum of the task priority and urgency order corresponding to each product is used as the corresponding handling order;

[0060] By utilizing the handling sequence of each product containing pressure-holding blocks, the corresponding handling route can be determined.

[0061] In this embodiment, since the task priority and urgency order of each product are considered at the same time, the determined handling order of each product is more accurate. The handling of each product according to the handling order forms a corresponding handling route, which can improve the rationality and accuracy of the handling route.

[0062] Optionally, a product pressure holding system further includes a first alarm device, which is connected to the pressure holding control system;

[0063] The first alarm device is used to trigger the first alarm sound when the margin of the pressure holding block in the pressure holding control system is less than the first preset value.

[0064] In this embodiment, since the total number of pressure-holding blocks in the pressure-holding control system is fixed, and these blocks may fall off during handling after being placed on the corresponding product, or be removed from the pressure-holding control system by the operator, the number of pressure-holding blocks in the control system may decrease. If, during the pressure-holding process for each product, the remaining amount of pressure-holding blocks in the pressure-holding control system is less than a first preset value, it indicates that the number of usable pressure-holding blocks is insufficient, which may prolong the time the product is not pressure-held, thereby reducing the efficiency of pressure holding. Therefore, when the remaining amount of pressure-holding blocks in the pressure-holding control system is less than the first preset value, a first alarm device is triggered to emit a first alarm sound, reminding the operator that the remaining amount of pressure-holding blocks in the pressure-holding control system is insufficient, so that the operator can be aware of the situation in a timely manner and take corresponding actions. These actions include picking up the pressure-holding blocks that have fallen to the ground and returning them to the pressure-holding control system, or removing a preset number of pressure-holding blocks and placing them into the pressure-holding control system.

[0065] Optionally, a product pressure holding system further includes a second alarm device, which is connected to the three-dimensional storage system;

[0066] The second alarm device is used to trigger a second alarm sound when the remaining space of the unstored product position in the three-dimensional storage system is less than a second preset value.

[0067] In this embodiment, since the number of storage locations in the three-dimensional storage system is limited, if every storage location is already occupied, no new products can be stored. In this case, it is necessary to adjust the production schedule and, in turn, the pressure holding schedule of each product in the pressure holding control system to prevent product accumulation and maintain the automation efficiency of the pressure holding process. Therefore, when the remaining space in the three-dimensional storage system without stored products is less than a second preset value, a second alarm device is triggered to emit a second alarm sound, alerting the operator to the insufficient remaining space in the three-dimensional storage system. This allows the operator to promptly understand the situation and take appropriate action.

Figure 2As shown, the system includes a front-end device 1, a product 11, a pressure holding control system 2, an AGV trolley 3, an automated storage system 4, and a product production line 5.

[0069] Figure 3 This is a schematic diagram of the pressure holding control system of the present invention, as shown below. Figure 3 As shown, the pressure holding control system 2 includes a motor-controlled moving roller conveyor 21, a carrier 22, a first pressure holding block 23, a second pressure holding block 24, a third pressure holding block 25, and four two-axis moving transfer units 26.

Each two-axis moving transfer unit 26 includes an X-axis 261, a Z-axis 262, and a gripper cylinder 263. The motor-controlled moving roller conveyor 21 is used to place the carrier 22. The carrier 22 is used to hold the product and place the first pressure holding block 23, the second pressure holding block 24, and the third pressure holding block 25 on the corresponding product. The two-axis moving transfer units 26 are used to clamp the product, the first pressure holding block 23, the second pressure holding block 24, and the third pressure holding block 25 using the gripper cylinder 263, and to move the product, the first pressure holding block 23, the second pressure holding block 24, and the third pressure holding block 25 using the X-axis 261 and the Z-axis 262.

[0070] Figure 4 This is a schematic diagram of the structure of the three-dimensional warehousing system of the present invention, as shown below. Figure 4 As shown, the automated storage and retrieval system includes a first storage area 4111, a second storage area 42, a third storage area 43, and a fourth storage area 44. Each of the first storage area 4111, the second storage area 42, the third storage area 43, and the fourth storage area 44 includes multiple storage locations. ， Each storage location in the first storage area 4111, the second storage area 42, the third storage area 43, or the fourth storage area 44 is used to store products of the corresponding category.

[0071] In a product pressure holding system, after the front-end equipment 1 produces and dispenses adhesive onto product 11, the gripper cylinder 263 in a two-axis motion transfer 26 of the pressure holding control system 2 clamps product 11. The X-axis 261 and Z-axis 262 of the two-axis motion transfer 26 are adjusted so that product 11 is placed on an empty carrier 22 on a motor-controlled motion roller line 21 in the pressure holding control system. Then, based on the incoming material information of product 11, the pressure holding control system 2 determines the corresponding pressure holding weight and duration for product 11, and uses the gripper cylinder 263 in the two-axis motion transfer 26 to clamp the pressure holding block corresponding to the pressure holding weight (e.g., a first pressure holding block 23, a second pressure holding block 24, or a third pressure holding block 25) and place it on product 11. An AGV trolley 3 transports product 11 with the pressure holding block to the corresponding storage location in the storage area of ​​the automated storage system and stores the corresponding pressure holding duration. The AGV trolley 3 transports the product 11, after the pressure holding time has ended, to the pressure holding control system 2. The pressure holding control system 2 uses a gripper cylinder 263 in a two-axis motion transfer 26 to remove the pressure holding block from the product 11 and store it, and uses a gripper cylinder 263 in a two-axis motion transfer 26 to remove the product 11 and place it on the product assembly line 5.
