Description

Technical Field

[0001] This application relates to the field of automation equipment technology, and in particular to an automatic epoxy resin filling machine. Background Technology

[0002] In current epoxy resin and other material potting production scenarios, existing potting equipment is the core tool supporting basic potting operations. Its technical architecture and operating mode are relatively simple, mainly consisting of a dispensing machine platform, a lead screw stepper motor, a dispensing needle valve, and basic start-up control components. The entire potting process is manually led, while relying on the potting equipment for assistance. First, the worker manually moves the product to be potted onto the designated working platform of the potting equipment. Relying on the worker's alignment and calibration operations, the potting equipment is then started to perform a single dispensing and potting action. After potting is completed, the worker removes the product and repeats the potting process for the next batch of products.

[0003] Therefore, in the above-mentioned potting process, the potting equipment only has basic glue filling function and no automated auxiliary module. It can only rely on manual handling of products and identification and inspection of the position, shape and integrity of the products to be potted on the mold. The overall process cannot achieve continuous and automated potting production operation. Utility Model Content

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] See Figure 1 and Figure 2This application first provides an embodiment of an automatic epoxy resin filling machine, which includes: a base cabinet 01, a controller, a conveying device 02, a robotic arm 03, an epoxy resin storage tank 04, a weighing device 05, a heating device 06, and a vision inspection mechanism; the controller is installed inside the base cabinet 01 and is electrically connected to the conveying device 02, the robotic arm 03, the weighing device 05, the heating device 06, and the vision inspection mechanism respectively; the conveying device 02 is installed at the front of the base cabinet 01, and the conveying device 02 is equipped with a positioning cylinder, a blocking cylinder, a lifting cylinder, a lifting platform driven by the lifting cylinder, and a waste collection box; the robotic arm 03 is installed in the middle of the base cabinet 01, and the robotic arm 03 is equipped with a lead screw stepper motor, a glue dispensing needle valve, and a rotary cylinder; The epoxy resin storage tank 04 and the weighing device 05 are both installed at the rear of the base cabinet 01, with the weighing device 05 corresponding to the epoxy resin storage tank 04; the heating device 06 is corresponding to the dispensing needle valve; the vision inspection mechanism is installed in the middle of the base cabinet 01 and is located within the working range of the robotic arm 03; the controller is used to coordinate the coordinated actions of the conveying device 02, the robotic arm 03, the weighing device 05, the heating device 06, and the vision inspection mechanism; the lead screw stepper motor is used to drive the dispensing needle valve to move along a preset trajectory, and the rotary cylinder is used to adjust the working angle of the dispensing needle valve; the weighing device 05 is used to monitor the remaining amount of raw material in the epoxy resin storage tank 04; the heating device 06 is used to prevent the epoxy resin from curing; and the vision inspection mechanism is used to detect the state of the product to be filled on the mold.

[0023] The components of this embodiment will be described below: Base Cabinet 01: Base Cabinet 01 is the mechanical skeleton and integrated platform of the entire epoxy resin automatic potting machine. It adopts a robust cabinet structure. Not only is the surface clearly divided into three functional areas—front, middle, and rear—along the potting process, providing physical support, but the internal space is also dedicated to installing core electrical components such as controllers, optimizing the spatial layout and facilitating centralized wiring, maintenance, and management of the equipment.

[0024] Controller: The controller is installed inside the base cabinet 01 and establishes signal interaction with the conveying device 02, robotic arm 03, weighing device 05, heating device 06 and vision inspection mechanism through electrical connections. It plays a key role in coordinating the coordinated actions of all components. It receives product status signals from the vision inspection mechanism and raw material balance signals from the weighing device 05. According to the preset program, it sends positioning and conveying commands to the conveying device 02, filling trajectory and angle adjustment commands to the robotic arm 03, and temperature control commands to the heating device 06. This ensures that the entire filling process proceeds at a precise pace and provides underlying logic support for the automated operation of the equipment.

[0025] Conveying Device 02: Installed at the front of the base cabinet 01, the conveying device 02 integrates a positioning cylinder, a blocking cylinder, a lifting cylinder, a lifting platform connected to the lifting cylinder, and a waste collection box. During the filling operation, the conveying device 02 can transport the product to be filled to the designated position. The positioning cylinder achieves precise lateral positioning of the product, the blocking cylinder achieves longitudinal limitation, and the lifting cylinder drives the lifting platform to adjust the product height to match the filling angle of the robotic arm 03. At the same time, for products that are determined to be unqualified by the visual inspection mechanism, the conveying device 02 can transport them to the waste collection box for centralized processing. The entire process requires no manual handling or screening, realizing full automation from loading, positioning to unloading.

[0026] Robotic Arm 03: Robotic Arm 03 is installed in the middle of the base cabinet 01 and is equipped with a lead screw stepper motor, a dispensing needle valve, and a rotary cylinder. The lead screw stepper motor drives the dispensing needle valve to move stably along a preset trajectory, ensuring that the dispensing needle valve can accurately align with the filling position of the product to be filled. The rotary cylinder can flexibly adjust the working angle of the dispensing needle valve to adapt to the filling needs of products with different shapes or different placement angles. Under the coordinated control of the controller, Robotic Arm 03 can automatically adjust its motion parameters based on the product status feedback from the vision inspection mechanism to achieve accurate filling of qualified products, avoiding the problems of existing equipment that can only fill along a fixed trajectory, have low accuracy, and poor adaptability.

[0027] Epoxy resin storage tank 04: Installed at the rear of the base cabinet 01, epoxy resin storage tank 04 is mainly used to store epoxy resin raw materials required for potting. Epoxy resin storage tank 04 is indirectly connected to the front robotic arm 03 via pipelines, ensuring a stable supply of epoxy resin to the dispensing needle valve. Simultaneously, epoxy resin storage tank 04 is correspondingly equipped with the rear weighing device 05, maintaining a stable supply of raw materials during consumption and preventing the potting process from stalling due to supply interruptions, thus providing a material guarantee for continuous automated operation.

[0028] Weighing device 05: The weighing device 05 is installed at the rear of the base cabinet 01, corresponding to the epoxy resin storage tank 04. It acquires weight data through close contact with the storage tank and converts the data into an electrical signal, which is then fed back to the controller. When the remaining raw material level is detected to be lower than a preset threshold, the controller can promptly issue a replenishment prompt, ensuring a sufficient supply of raw material in the storage tank at all times. This avoids interruptions in the potting operation or unstable glue output due to insufficient raw material, solving the problem that existing equipment cannot monitor the remaining raw material level in real time and is prone to affecting production efficiency due to material shortages.

[0029] Heating device 06: The heating device 06 is correspondingly set up with the dispensing needle valve. Because epoxy resin contains quartz sand, it is prone to curing and clumping at room temperature or low temperature, which can lead to blockage of the dispensing needle valve. The heating device 06 can continuously provide a suitable temperature to keep the epoxy resin in the dispensing needle valve and the delivery pipeline in a fluid state, ensuring smooth dispensing. At the same time, the heating device 06 can accurately control the heating temperature under the control of the controller, avoiding excessive temperature from affecting the performance of epoxy resin, further preventing blockage of the dispensing needle valve, and significantly improving the reliability and continuity of the automatic epoxy resin potting machine.

[0030] Visual inspection mechanism: The visual inspection mechanism is installed in the middle of the base cabinet 01 and within the working range of the robotic arm 03. Before the filling action is started, the status of the product to be filled on the mold is fully inspected, including identifying whether the product is missing, damaged, or misaligned. After the inspection is completed, the visual inspection mechanism converts the product status signal into an electrical signal and transmits it to the controller. If a defective product is found, the controller will instruct the robotic arm 03 to automatically close the dispensing needle valve when it moves to the position of the product, thus avoiding ineffective filling of defective products and improving screening efficiency and filling quality stability.

[0031] In this embodiment, the conveying device 02 of the automatic epoxy resin filling machine, through the cooperation of positioning cylinders, blocking cylinders, lifting cylinders, and lifting platforms, can automatically complete the conveying, positioning, and lifting of the products to be filled, replacing manual loading and unloading and alignment operations, and reducing manual intervention. The vision inspection mechanism can automatically detect the status of the products on the mold before the robotic arm 03 operates. With the linkage between the controller and the robotic arm 03, it can avoid unqualified products without the need for manual pre-inspection and handling. The robotic arm 03 is driven by a lead screw stepper motor to move the dispensing needle valve along a preset trajectory and the rotary cylinder adjusts the working angle, realizing multi-dimensional precise filling. The controller coordinates the collaborative work of the conveying device 02, robotic arm 03, heating device 06, and other components. At the same time, the rear weighing device 05 automatically monitors the remaining raw material, and the heating device 06 prevents the epoxy resin from curing, further reducing the need for manual maintenance. Thus, while comprehensively improving the automation level, production efficiency, and product yield of the filling operation, it greatly reduces the dependence on manual operation.

[0032] In an optional embodiment, the controller is a four-axis high-speed positioning programmable controller. The signal input terminals of the controller are electrically connected to the vision inspection mechanism and the weighing device 05, respectively, and the signal output terminals of the controller are electrically connected to the conveying device 02, the robotic arm 03 and the heating device 06, respectively.

[0033] In this optional embodiment, the controller employs a four-axis high-speed positioning programmable controller. The controller's signal input is electrically connected to the vision inspection mechanism and the weighing device 05, allowing it to receive real-time status signals from the vision inspection mechanism regarding product defects, damage, and positional deviations on the mold, as well as raw material balance data from the epoxy resin storage tank 04 transmitted by the weighing device 05. This provides real-time data for accurate decision-making. The signal output is connected to the conveying device 02, the robotic arm 03, and the heating device 06. Based on the input signals, it can send positioning, conveying, and waste disposal commands to the conveying device 02, issue dispensing trajectory and angle adjustment commands to the robotic arm 03, and transmit temperature control signals to the heating device 06, completing a closed-loop control process of detection, judgment, and execution. Therefore, the controller's four-axis high-speed positioning capability ensures precise synchronous control of the multi-dimensional movement of the robotic arm 03. Combined with its programmable characteristics, it can flexibly adapt to the potting requirements of different products, significantly improving the automation level and operational accuracy of the potting process.

[0034] In an optional embodiment, the conveying device 02 further includes a conveyor belt and a drive motor, the output shaft of which is connected to the drive roller of the conveyor belt via a coupling; the positioning cylinder and the blocking cylinder are sequentially fixed on the table surface at the front of the base cabinet 01 along the conveying direction of the conveyor belt.

[0035] In an optional embodiment, the piston rod of the positioning cylinder is positioned towards the inside of the conveyor belt, and the piston rod of the blocking cylinder is positioned vertically upward; the lifting platform is located below the middle of the conveyor belt; the cylinder body of the lifting cylinder is fixed inside the base cabinet 01, and the piston rod of the lifting cylinder extends vertically upward through the platform of the base cabinet 01 and is bolted to the bottom of the lifting platform.

[0036] In the two optional embodiments described above, the power end of the conveying device 02 consists of a conveyor belt and a drive motor. The output shaft of the drive motor is rigidly connected to the drive roller of the conveyor belt via a coupling, allowing for stable control of the belt conveying speed through the motor speed, providing power support for continuous product conveying. The positioning end of the conveying device 02, along the conveying direction of the conveyor belt, has a positioning cylinder and a blocking cylinder sequentially fixed on the platform at the front of the base cabinet 01. The piston rod of the positioning cylinder faces inward towards the conveyor belt, enabling it to push the mold laterally for left-right alignment. The piston rod of the blocking cylinder extends vertically upward, intercepting the mold longitudinally for front-back positioning. The piston rods of both cylinders cooperate to ensure that the mold accurately stops at the preset working position during belt conveying. Meanwhile, a lifting platform is located below the middle of the conveyor belt. Its height adjustment depends on the lifting cylinder fixed inside the base cabinet 01. The cylinder body of the lifting cylinder is stably installed inside the cabinet. After the piston rod extends vertically upward through the cabinet platform, it is rigidly connected to the bottom of the lifting platform by bolts. According to the filling height requirements of the robotic arm 03, the lifting platform can be driven to move the mold up and down, ultimately realizing automatic conveying, positioning and height adjustment calibration.

[0037] In an optional embodiment, the robotic arm 03 is a four-axis robotic arm, and the execution end of the four-axis robotic arm is welded with an L-shaped mounting bracket; the housing of the lead screw stepper motor is fixed to the horizontal section of the L-shaped mounting bracket by bolts, and the output shaft of the lead screw stepper motor is connected to the tail end of the dispensing needle valve through a ball screw pair; the cylinder body of the rotary cylinder is fixed to the vertical section of the L-shaped mounting bracket by bolts, and the output shaft of the rotary cylinder is fixedly connected to the middle of the dispensing needle valve through a flange.

[0038] In this optional embodiment, the robotic arm 03 adopts a four-axis structure. Its execution end is fixed with an L-shaped mounting bracket welded on, integrating the lead screw stepper motor, rotary cylinder, and dispensing needle valve into a coordinated potting execution unit, ensuring precise synchronization of the movements of multiple components. The horizontal section of the L-shaped mounting bracket is used to fix the lead screw stepper motor; the motor housing is tightly bolted to the surface of the horizontal section. The output shaft of the lead screw stepper motor is connected to the tail of the dispensing needle valve via a ball screw pair. Utilizing the high precision and low friction characteristics of the ball screw pair, the lead screw stepper motor can drive the dispensing needle valve to move stably along a preset trajectory, accurately aligning it with the filling position of the product to be potted. The vertical section of the L-shaped mounting bracket is used to mount the rotary cylinder. The cylinder body is also fixed with bolts, and its output shaft is rigidly connected to the middle of the dispensing needle valve via a flange, enabling the dispensing needle valve to rotate flexibly around its own axis. This adapts to the potting needs of molds with different shapes or products with different placement angles, further improving the automation and adaptability of the potting operation.

[0039] In an optional embodiment, the dispensing needle valve includes a valve body, a valve core, and a feed tube. The valve core is embedded inside the valve body and is made of tungsten steel. One end of the feed tube is connected to the outlet of the epoxy resin storage tank 04 via a hose, and the other end is threaded to the inlet of the valve body.

[0040] In this optional embodiment, the dispensing needle valve is composed of a valve body, a valve core, and a feed tube. The structural design and material selection of each component of the dispensing needle valve are optimized to meet the requirements of high-hardness silica sand, easily curable epoxy resin, and automated potting. The valve core, as a key component controlling the dispensing flow and accuracy, is made of tungsten carbide. Because the silica sand in epoxy resin is extremely hard, ordinary metal valve cores are prone to wear, leading to decreased dispensing accuracy or leakage. The high hardness and wear resistance of tungsten carbide significantly extend the service life of the valve core. Furthermore, the valve core is fixed inside the valve body through an embedded method, ensuring sealing during valve core movement and avoiding excessive friction between the valve core and the valve body. The feed pipe is responsible for conveying epoxy resin. One end of the feed pipe is connected to the outlet of the epoxy resin storage tank 04 through a hose. The flexibility of the hose can adapt to the positional changes when the robotic arm 03 drives the dispensing needle valve. The other end is fixed to the feed port of the valve body through a threaded connection. The threaded connection not only ensures the sealing during the material conveying process and prevents glue leakage, but also facilitates the maintenance and disassembly of subsequent components. Ultimately, the dispensing needle valve can achieve stable glue dispensing while meeting the requirements of automated operation and long-term durability of the equipment.

[0041] In an optional embodiment, the vision inspection mechanism includes an industrial camera, a lens, and an image analysis module. The industrial camera is fixed to the platform in the middle of the base cabinet 01 by a gantry bracket, and the lens of the industrial camera faces vertically downward toward the lifting platform of the conveying device 02. The image analysis module is integrated inside the controller. The signal input terminal of the image analysis module is connected to the output terminal of the industrial camera via a network cable, and the signal output terminal of the image analysis module is electrically connected to the controller.

[0042] In this optional embodiment, the visual inspection mechanism consists of an industrial camera, a lens, and an image analysis module. The industrial camera is securely fixed to the platform in the middle of the base cabinet 01 via a gantry bracket, avoiding collision interference during the operation of the robotic arm 03 and allowing the camera lens to be vertically and accurately aligned with the lifting platform of the conveyor device 02. The lifting platform is the area where the product to be potted rests after positioning; the downward-facing lens can fully capture the placement of the product on the mold, providing a clear image basis for subsequent inspection. Furthermore, the image analysis module is integrated into the controller, reducing external line interference and shortening signal transmission distance. The signal input of the image analysis module is connected to the output of the industrial camera via a network cable, stably receiving product image data captured by the camera. After the built-in algorithm of the image analysis module identifies whether there are gaps, damage, or positional misalignment in the product, the signal output of the image analysis module is directly electrically connected to the controller, converting the inspection results into control signals and transmitting them to the controller. The controller then instructs the robotic arm 03 to adjust its working trajectory, avoiding potting unqualified products and significantly improving inspection efficiency and potting quality stability.

[0043] In an optional embodiment, the epoxy resin automatic potting machine also includes a dispensing platform located directly below the robotic arm 03. The bottom of the dispensing platform is connected to the table surface of the base cabinet 01 via a screw servo mechanism; the drive end of the screw servo mechanism is electrically connected to the output end of the controller.

[0044] In this optional embodiment, the dispensing platform is precisely positioned directly below the robotic arm 03, ensuring that when the robotic arm 03 moves the dispensing needle valve, it remains aligned with the product to be potted on the platform, preventing potting offset due to positional deviation. The bottom of the dispensing platform is connected to the table surface of the base cabinet 01 via a screw servo mechanism. This screw servo mechanism features high displacement accuracy and stable operation, enabling precise adjustment of the dispensing platform to minute distances, overcoming the limitations of traditional fixed platforms that cannot adapt to the fine-tuning requirements of different product potting heights or positions. Simultaneously, the drive end of the screw servo mechanism is electrically connected to the output end of the controller. The controller can send displacement control commands to the screw servo mechanism based on the product position signal fed back by the vision inspection mechanism, adjusting the position of the dispensing platform in real time. This ensures that the product on the platform and the dispensing needle valve maintain the optimal relative potting position, ultimately achieving ±10mg dispensing volume accuracy control in conjunction with the robotic arm 03 and the dispensing needle valve, further improving the stability of potting quality.

[0045] In one optional embodiment, a 5mm thick rubber anti-slip pad is attached to the upper surface of the lifting platform, and the upper surface of the rubber anti-slip pad has a diamond-shaped anti-slip pattern.

[0046] In this optional embodiment, the anti-slip pad layer of the lifting platform is made of rubber, which is adhered and fixed to the upper surface of the lifting platform with a thickness of 5mm. The rubber material itself has good elasticity and a coefficient of friction, which can not only buffer the mold when it is placed to avoid damage caused by hard contact between the mold and the platform, but also initially prevent the mold from sliding through its own friction. At the same time, the upper surface of the rubber anti-slip pad layer is processed with diamond-shaped anti-slip texture. Compared with ordinary flat or straight texture, the diamond texture can further increase the contact area and frictional resistance with the bottom of the mold. Even if the lifting platform generates slight vibration during the lifting process, or there is slight impact force when the conveying device 02 transports the mold, it can effectively prevent the mold from shifting laterally or longitudinally. This design works directly with the positioning cylinder and blocking cylinder of the conveying device 02 to ensure that the mold always maintains a precise positioning state on the lifting platform. This provides a stable foundation for the subsequent visual inspection mechanism to accurately identify the product status and for the robotic arm 03 to accurately fill the mold, avoiding filling position deviation or detection misjudgment due to mold displacement.

[0047] In an optional embodiment, the waste collection box is a cuboid structure with an open top. One side of the waste collection box is hinged to the edge of the tabletop of the base cabinet 01 via a hinge, and the other side is detachably connected to the tabletop of the base cabinet 01 via a buckle. A disposable plastic inner bag is placed inside the waste collection box.

[0048] In this optional embodiment, the waste collection box is a dedicated storage component for handling defective products in the automatic epoxy resin filling machine. It features a rectangular structure with an open top, ensuring that defective products conveyed by the conveyor device 02 fall smoothly into the box. The rectangular shape fits the installation space of the front table of the base cabinet 01, avoiding the occupation of additional working area. Furthermore, one side of the waste collection box is hinged to the edge of the base cabinet 01 tabletop, allowing for flipping and opening around the hinge axis. The other side is detachably connected to the tabletop via a latch, ensuring the stability of the collection box in the non-cleaning state and allowing for quick unfastening and flipping of the box when cleaning is needed, simplifying the operation process. Additionally, a disposable plastic liner bag is placed inside the waste collection box to directly collect the falling defective products and any residual waste adhesive. Cleaning does not require contact with the waste; simply remove and replace the liner bag, avoiding cleaning difficulties caused by adhesive residue on the inner wall of the collection box.
