Description

Technical Field

[0001] This utility model belongs to the technical field of copper clad laminate and printed circuit board manufacturing, and relates to a cooling device for a double-layer tabletop buffer pad. Background Technology

[0002] In the lamination process of copper clad laminates and printed circuit boards, cushioning pads are an important auxiliary material that needs to be recycled. The cushioning pads undergo a high-temperature lamination process along with the product, and their temperature is typically around 100°C when they are removed from the press. If the pad temperature is not effectively reduced before reuse, the residual high temperature will cause the prepreg to cure prematurely, resulting in quality defects such as dried flowers and microbubbles in the final product, severely impacting product yield.

[0003] Currently, cooling of buffer pads mainly relies on traditional cooling platforms, which are typically single, fixed surfaces. These platforms not only occupy a large amount of space but are also difficult to integrate with existing automated distribution lines. Furthermore, these cooling platforms require additional manpower for handling and equipment modifications, increasing production costs and operational complexity.

[0004] Although existing cooling platforms can cool the buffer pads to some extent, there are still some obvious problems and shortcomings, as follows: 1. Traditional cooling platforms are single fixed platforms, occupying a large space and unable to be linked with automatic distribution line equipment; 2. Existing cooling platforms cannot adapt to buffer pads of different sizes, resulting in low cooling efficiency; 3. The cooled pads need to be manually handled, increasing labor costs and operational complexity, and reducing production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a double-layered tabletop buffer plate cooling device that can save space, adapt to various sizes, and can be efficiently linked with existing automated production lines to improve production efficiency and reduce operating costs in the CCL / PCB industry.

[0006] The objective of this utility model is achieved through the following technical solution: A cooling device for a double-layered tabletop with a buffer pad, comprising: The rack has a double-layer structure, with the upper layer being a cooling platform for cooling high-temperature buffer pads and the lower layer being a temporary storage platform for storing the cooled buffer pads. A slide rail and guide wheel system, wherein the slide rail is mounted on the frame above the temporary storage platform, and the guide wheel is mounted on the bottom of the cooling platform. The guide wheel cooperates with the slide rail to enable the cooling platform to move laterally relative to the temporary storage platform. The position detection and control system includes a photoelectric sensor for detecting the moving position of the cooling platform and a PLC controller. The PLC controller is electrically connected to the photoelectric sensor and is used to control the movement of the cooling platform according to the received position signal and the pad size signal. And an automated transport crane, which is positioned above the cooling platform to transport the high-temperature buffer pads onto the cooling platform and to transport the cooled buffer pads from the cooling platform to a designated position on the temporary storage platform.

[0007] The PLC controller is configured to receive pad size information from the upstream production line and control the cooling platform to move above the area of ​​the temporary storage platform corresponding to the current pad size based on the information.

[0008] As a further improvement of this utility model, the cooling platform is a water-cooled platform with a cooling channel inside. The cooling channel can be a coil type, a serpentine tube type, or a matrix type pipeline. The two ends of the channel are respectively connected to the cooling water supply system and the return system for introducing cooling water.

[0009] As a further improvement of this utility model, the slide rail and guide wheel system includes two sets of slide rails, one set for guiding the movement of the cooling platform and the other set for guiding the movement of the automatic transport crane.

[0010] As a further improvement of this utility model, the inductive photoelectric sensor is a distance photoelectric sensor, which is respectively installed on the side of the cooling platform and the automatic transport crane, for real-time detection of their respective positions on the slide rail.

[0011] As a further improvement of this utility model, the automatic handling crane is equipped with a vacuum suction cup for picking up and releasing the buffer pad.

[0012] As a further improvement of this utility model, the temporary storage platform is divided into multiple areas for storing buffer pads of different sizes.

[0013] The above technical solution has the following beneficial effects: 1. High space utilization: The innovative double-layer table design vertically expands the functionality of the original automatic dispensing equipment, effectively reducing space occupation and improving the utilization efficiency of the production area.

[0014] 2. Automation and Intelligence: By combining photoelectric sensors with a PLC controller, the automatic and precise adjustment of the cooling platform position and the flexible cooling of buffer pads of various sizes are achieved. No manual handling is required, which reduces labor costs and improves production efficiency.

[0015] 3. Improved production efficiency: The integrated automatic suction and lifting system allows the cooled pallets to be automatically returned to the temporary storage platform, forming a complete automated production line that reduces manual handling and improves production efficiency.

[0016] 4. High adaptability and low modification cost: The movable cooling platform design allows it to avoid the operating space of the lower temporary storage platform, enabling the cooling platform to be moved and improving its versatility and flexibility. This device is easily integrated with existing automatic distribution line equipment without requiring large-scale modifications to the main line, thus reducing implementation costs.

[0017] 5. Product quality assurance: Through controllable forced cooling, the temperature of the pad is ensured to be reduced quickly and evenly to the process requirements (such as below 35℃), thus avoiding product quality defects caused by excessively high pad temperature from the source.

[0024] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0025] First embodiment, such as Figures 1-3 As shown, a double-layered platform buffer plate cooling device includes a double-layered frame 1, a slide rail and guide wheel system, and a position detection and control system.

[0026] The frame 1 has a double-layer structure. The upper layer of the frame 1 is a cooling platform 11 for cooling the high-temperature buffer pads, and the lower layer of the frame 1 is a temporary storage platform 12 for storing the cooled buffer pads. The double-layer layout can effectively reduce the space occupied by the equipment and improve the utilization rate of the production area.

[0027] The cooling platform 11 is preferably a water-cooled platform with a pre-set cooling channel inside. This cooling channel can be implemented using coiled, serpentine, or matrix piping, etc., with the two ends of the channel connected to a cooling water supply system and a return system, respectively. During operation, flowing cooling water with a stable temperature below 25°C is continuously supplied to the cooling channel. After the high-temperature buffer pad is placed on the upper surface of the cooling platform 11, rapid cooling is achieved through heat conduction. During the cooling process, the cooling water carries away the heat from the pad and continuously circulates and refreshes, ensuring that the pad temperature is uniformly reduced to below 35°C, meeting the process requirement.

[0028] The design of the aforementioned cooling platform 11 avoids quality defects in subsequent processed products caused by residual high temperature on the buffer pad from the source. At the same time, the combination of water-cooled cooling and double-layer layout provides a structural basis for the equipment to adapt to different production scenarios, combining practicality and flexibility.

[0029] The slide rail and guide wheel system includes two sets of slide rails 2 and 3 and matching guide wheels, providing stable guidance for the moving parts of the device. Slide rails 2 are arranged parallel to each other on both sides of the frame 1 above the temporary storage platform 12. Several guide wheels are correspondingly installed on the bottom of the cooling platform 11, rolling in cooperation with the slide rails 2, allowing the cooling platform 11 to move smoothly laterally relative to the temporary storage platform 12 along the direction of the slide rails 2. Slide rails 3 are set on the frame 1 above the cooling platform 11, and guide wheels are set on the bottom of the automatic transport crane 4. The guide wheels cooperate with the slide rails 3 to guide the movement of the automatic transport crane 4. The automatic transport crane 4 is equipped with vacuum suction cups; the number of suction cups can be flexibly set according to the size of the buffer pad, achieving stable suction and smooth release of the buffer pad through the principle of negative pressure adsorption.

[0030] The position detection and control system includes photoelectric sensors for detecting the moving position of the cooling platform 11 and a PLC controller. The PLC controller is electrically connected to the photoelectric sensors and controls the movement of the cooling platform 11 based on the received position signals and pad size signals. Specifically, the photoelectric sensors are distance sensors, which are respectively installed on the sides of the cooling platform 11 and the automatic transport crane 4. They are used to collect real-time position signals of the cooling platform 11 on the slide rail 2 and the automatic transport crane 4 on the slide rail 3, and synchronously transmit the signals to the PLC controller.

[0031] In this design, the temporary storage platform 12 adopts a partitioned design, divided into three independent storage areas along its length, corresponding to the storage of cooled buffer pads of sizes A, B, and C, respectively. Each area is clearly distinguished by a label structure, facilitating precise positioning by the automated guided vehicle (AGV) crane 4. This partitioned layout can be adjusted in terms of the number or size of the areas according to actual production needs, using an equivalent implementation method to accommodate the storage requirements of buffer pads of more specifications.

[0032] The PLC controller pre-stores the position parameters of the temporary storage area corresponding to each size of pad and is configured with a signal receiving module to receive the current size information of the buffer pad to be cooled transmitted from the upstream production line in real time. Based on the received size information and the real-time position signal of the cooling platform 11 fed back by the photoelectric sensor, the PLC controller outputs control commands after calculation by the built-in program, driving the cooling platform 11 to move precisely along the slide rail 2 to directly above the corresponding temporary storage area, ensuring that the transfer path of the cooled pad is the shortest.

[0033] The automated handling crane 4 receives coordinated instructions from the PLC controller and first smoothly transports the high-temperature buffer pads conveyed upstream to the cooling platform 11 for cooling. Once the pads reach the required temperature, they are precisely grabbed and transported to the designated area on the temporary storage platform 12 for storage. The entire cooling, transfer, and storage process is fully automated, requiring no manual intervention, thus ensuring production continuity and the neatness of the pad storage.

[0034] The slide rails 2 and 3, along with their matching guide wheels, photoelectric sensors, PLC controllers, and automatic handling cranes 4 involved in this utility model are all mature existing technologies in the industrial production field, which can be directly purchased from the market without the need for additional customized development.

[0035] The core innovation of this utility model lies in the optimized integration of the aforementioned existing technical components with the double-layer frame 1, forming an integrated buffer pad cooling device through a reasonable layout. The design of the upper cooling platform 11 and the lower temporary storage platform 12 of the double-layer frame significantly reduces the space occupied by the equipment; the coordinated operation of each component realizes the fully automated process of automatic handling, precise cooling, and classified storage of high-temperature pads, effectively improving production efficiency, while eliminating manual handling and operation, significantly reducing enterprise operating costs, and combining practicality and economy.

[0036] The working process of the buffer pad cooling device provided by this utility model is as follows: During production, the PLC controller moves the cooling platform 11 in advance via a slide rail to the area above the temporary storage platform for pads of different sizes, based on the upcoming pad size, in order to avoid interference.

[0037] The automated handling crane 4 receives a high-temperature buffer pad with a temperature of about 100°C from upstream and places it on the cooling platform 11.

[0038] The high-temperature pad is placed on a cooling platform 11 with cooling water for a period of time (e.g., 30 to 60 seconds, the specific time can be set according to process requirements) to rapidly reduce its temperature to a safe range below 35°C.

[0039] After cooling is complete, the automatic transport crane 4 operates again, using a vacuum suction cup to pick up the cooled pad and move it horizontally to the top of the corresponding storage platform 12 on the lower level. Then, the pad is released, completing a full automatic cooling and transfer process.

[0040] For pads of different sizes, the PLC controller will automatically coordinate the movement path and stop position of the cooling platform 11 and the automatic transport crane 4 according to the received size signal to achieve fully automatic adaptation.

[0041] Through the above-mentioned device and method, this utility model effectively solves many shortcomings of traditional fixed cooling platforms and realizes efficient, energy-saving and automated operation of the buffer plate cooling process.
