Description

Technical Field

[0001] This invention relates to the field of die-cutting technology, and more particularly to an automated production line for ultrasonic die-cutting and adhesive application. Background Technology

[0002] Punching is a process in which a die (punch) moves under the action of a press, applying pressure to the raw material and cutting it off. A search revealed Chinese invention patent application CN202511604773.5, which provides a punching device for magnesium alloy die castings. This device uses ultrasonic vibration punching technology and is primarily used for processing metal parts. In existing plastic processing technology, products are generally connected to sprues, which are the runners created after injection molding—the waste material remaining after product removal. Common methods for removing sprues include breaking them off, cutting them with pliers, or shaving them off with a blade. These methods are slow, rely on manual labor, and result in inconsistent product quality and low efficiency. Furthermore, some products require single-sided adhesive application, which is also typically done manually, leading to low production efficiency and inconsistent processing quality, highlighting the shortcomings of existing technologies. Summary of the Invention

[0003] The purpose of this invention is to provide an automated production line for ultrasonic punching and adhesive application to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automated production line for ultrasonic punching and adhesive application includes an ultrasonic punching machine, an electric slide rail, an upper gripping mechanism, a lower gripping mechanism, a punching station, a finished product placement station, a film placement station, a raw material placement station, a lower die, and a discharge port. The punching station, finished product placement station, film placement station, and raw material placement station are located within the path of the sliding table of the electric slide rail. The sliding table of the electric slide rail moves horizontally and is equipped with an upper gripping mechanism. The upper and lower gripping mechanisms are used to control the vertical movement of their respective grippers. The punching station is equipped with a lower die, which has a discharge port extending vertically and corresponding vertically to the ultrasonic punching machine. The lower gripping mechanism is located directly below the lower die. The upper gripping mechanism, lower die, and upper gripping mechanism can correspond to each other from top to bottom. The ultrasonic punching machine, electric slide rail, upper gripping mechanism, lower gripping mechanism, and electrical control system are electrically connected, and the electrical control system is powered by an external power source.

[0006] Based on the above technical solution, the ultrasonic punching machine includes a lifting mechanism, a support base, an ultrasonic vibration generator, a punch, and a temperature sensor. The lifting mechanism is equipped with the support base and is used to control the up-and-down movement of the support base. An ultrasonic vibration generator is installed inside the support base, and a punch is fixed at the bottom of the ultrasonic vibration generator. The punch corresponds vertically to the lower die. A temperature sensor is installed inside the support base and is used to detect the temperature of the punch. The lifting mechanism is controlled to move the support base up and down by electric, pneumatic, hydraulic, or mechanical transmission. The lifting mechanism, ultrasonic vibration generator, and temperature sensor are electrically connected to the electrical control system.

[0007] Based on the above technical solution, molds adapted to the film and raw materials are respectively installed in the film placement station and the raw material placement station for positioning the film and raw materials respectively.

[0008] Based on the above technical solution, the upper gripping mechanism and the lower gripping mechanism respectively include a telescopic mechanism, a sensor assembly, grippers, and a negative pressure device. The grippers include a support plate, main negative pressure rods, and main negative pressure heads. The telescopic mechanism is equipped with a support plate and controls the vertical movement of the support plate using electric, pneumatic, hydraulic, or mechanical transmission. The sensor assembly is used to detect the vertical movement distance of the grippers. The support plate is tightly fitted with multiple main negative pressure rods, which are arranged vertically. The main negative pressure rods on the same support plate are arranged horizontally. Each main negative pressure rod has a rubber main negative pressure head fixedly connected to its end near the material to be adsorbed. The main negative pressure head extends vertically through the material. The other end of the main negative pressure rod is connected to the negative pressure device through a pipe to achieve a controllable negative pressure effect. The main negative pressure head of the lower gripping mechanism is always vertically aligned with the discharge port. Each main negative pressure head of the upper gripping mechanism can be vertically aligned with the discharge port. The telescopic mechanism, sensor assembly, negative pressure device, and electrical control system are electrically connected.

[0009] Based on the above technical solution, the ultrasonic punching and adhesive application automated production line also includes a waste placement station, which is also located within the sliding table movement path of the electric slide rail. The upper gripping mechanism also includes a secondary negative pressure rod and a secondary negative pressure head. The upper gripping mechanism is fixed with a secondary negative pressure rod, which is arranged parallel to the main negative pressure rod. The upper part is connected to the negative pressure device through a pipe to achieve a controllable negative pressure effect. The bottom of the secondary negative pressure rod is fixedly connected to a rubber secondary negative pressure head. The position of the secondary negative pressure head where the upper gripping mechanism is located is higher than the positions of each main negative pressure head. The top of the lower die has a receiving groove for accommodating waste. When the discharge port is vertically aligned with the main negative pressure rod of the upper gripping mechanism, the receiving groove is vertically aligned with the secondary negative pressure rod.

[0010] Compared with the prior art, the present invention has the following advantages: The present invention, through the cooperation of an ultrasonic punching machine, an electric slide rail, an upper gripping mechanism, a lower gripping mechanism, a lower die, and a discharge port, can realize automated punching and adhesive application; by setting the die to position the film and raw materials, it is convenient for the upper gripping mechanism to grip the raw materials and for adhesive application; by setting the waste placement station, a secondary negative pressure rod, a secondary negative pressure head, and a receiving groove, it realizes the automatic cleaning of waste products, thereby improving work efficiency and quality.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] like Figures 1-5As shown, an automated production line for ultrasonic punching and adhesive application includes an ultrasonic punching machine 1, an electric slide rail 2, an upper gripping mechanism 3, a lower gripping mechanism 4, a punching station 5, a finished product placement station 6, a film placement station 7, a raw material placement station 8, a lower die 9, and a discharge port 10. The punching station 5, finished product placement station 6, film placement station 7, and raw material placement station 8 are located within the movement path of the slide table of the electric slide rail 2. The slide table of the electric slide rail 2 moves horizontally, and its slide table is equipped with an upper gripping mechanism 3. The lower gripping mechanism 3 and the lower gripping mechanism 4 are used to control the vertical movement of their respective grippers 18. The punching station 5 is equipped with a lower die 9, which has a discharge port 10 running through it vertically and corresponds vertically to the ultrasonic punching machine 1. The lower gripping mechanism 4 is located directly below the lower die 9. The upper gripping mechanism 3, the lower die 9, and the upper gripping mechanism 4 can correspond to each other from top to bottom. The ultrasonic punching machine 1, the electric slide rail 2, the upper gripping mechanism 3, the lower gripping mechanism 4, and the electrical control system are electrically connected. The electrical control system is powered by an external power source.

[0019] In operation, the plastic raw material to be punched is placed at the raw material placement station 8, and the film (with a layer of double-sided adhesive removed from the protective mold) is placed at the film placement station 7, with the adhesive side of the film facing upwards. The electrical control system then controls the upper gripping mechanism 3 to move its grippers 18 downwards to grip the raw material and then upwards. Subsequently, under the action of the electric slide rail 2, it moves to the punching station 5 and lowers again to place the raw material. Then, the grippers 18 move upwards, and under the control of the electric slide rail 2, the upper gripping mechanism 3 moves away from the punching station 5. The lower gripping mechanism 4 then controls the grippers 18 to move upwards to grip the product portion of the raw material. Finally, the ultrasonic punching machine 1 applies action to the lower mold 9 and the raw material. The process involves punching the raw material, separating the finished product from the waste. Then, the electric slide rail 2 controls the upper gripping mechanism 3 to approach the punching station 5. The upper gripping mechanism 3 controls the gripper 18 to move downwards to grip the raw material and then upwards. During this process, the lower gripping mechanism 4 releases the gripper 18 from the raw material. Driven by the electric slide rail 2, the upper gripping mechanism 3 moves to the film placement station 7, controls the gripper 18 to move downwards to adhere to the film, and then moves upwards and, driven by the electric slide rail 2, moves to the finished product placement station 6 to place the film. Finally, the waste is manually removed, and the raw material and film are placed back in place. This automated punching and adhesive application process results in higher production efficiency and better processing quality.

[0020] The ultrasonic punching machine 1 includes a lifting mechanism 11, a support base 12, an ultrasonic vibration generator 13, a punch 14, and a temperature sensor 15. The lifting mechanism 11 is equipped with the support base 12 and is used to control the up and down movement of the support base 12. The ultrasonic vibration generator 13 is installed inside the support base 12, and the punch 14 is fixed at the bottom of the ultrasonic vibration generator 13. The punch 14 corresponds vertically to the lower die 9. The temperature sensor 15 is installed inside the support base 12 and is used to detect the temperature of the punch 14. The lifting mechanism 11 controls the up and down movement of the support base 12 by electric, pneumatic, hydraulic, or mechanical transmission. The lifting mechanism 11, the ultrasonic vibration generator 13, and the temperature sensor 15 are electrically connected to the electrical control system.

[0021] The ultrasonic vibration generator 13 drives the punch 14 to generate high-frequency vibration. When the punch 14 acts on the raw material, it directly cuts it through vibration and pressure. Simultaneously, the high-frequency vibration causes localized high-frequency friction in the raw material, generating high temperatures and softening it locally. This softening, combined with the punch 14's action, cuts the plastic part, improving the quality of the cut surface and reducing burrs. The temperature sensor 15 is an infrared temperature sensor that detects the temperature of the material during cutting to help adjust the vibration frequency. This prevents excessively high vibration frequencies from causing the raw material to overheat and soften, thus reducing the quality of the cut surface.

[0022] The film placement station 7 and the raw material placement station 8 are respectively equipped with molds adapted to the film and raw materials for positioning the film and raw materials respectively.

[0023] Furthermore, by setting molds to position the film and raw materials, it is easier for the upper gripping mechanism 3 to grip the raw materials and to apply adhesive, thereby improving work efficiency and quality.

[0024] The upper gripping mechanism 3 and the lower gripping mechanism 4 each include a telescopic mechanism 16, a sensor assembly 17, a gripper 18, and a negative pressure device. The gripper 18 includes a support plate 19, main negative pressure rods 20, and a main negative pressure head 21. The telescopic mechanism 16 is equipped with the support plate 19. The telescopic mechanism 16 controls the vertical movement of the support plate 19 by electric, pneumatic, hydraulic, or mechanical transmission. The sensor assembly 17 is used to detect the distance of the vertical movement of the gripper 18. The support plate 19 is tightly fitted with multiple main negative pressure rods 20, which are arranged vertically along the same support plate 19. The main negative pressure rods 20 at position 9 are arranged horizontally. Each main negative pressure rod 20 has a rubber main negative pressure head 21 fixedly connected to its end near the material to be adsorbed. The main negative pressure head 21 runs vertically through the rod. The other end of the main negative pressure rod 20 is connected to the negative pressure device through a pipe to achieve a controllable negative pressure effect. The main negative pressure head 21 of the lower gripping mechanism 4 is always vertically aligned with the discharge port 10. Each main negative pressure head 21 of the upper gripping mechanism 3 can be vertically aligned with the discharge port 10. The telescopic mechanism 16, sensor assembly 17, negative pressure device and electrical control system are electrically connected.

[0025] Furthermore, the telescopic mechanism 16 drives the gripper 18 to move up and down, and the sensor assembly 17 (range sensor) determines the distance the gripper 18 moves up and down. The negative pressure device controls whether there is negative pressure, thereby creating a negative pressure effect through the main negative pressure rod 20 and the main negative pressure head 21, thereby achieving the gripping and releasing effect of raw materials and products.

[0026] The ultrasonic punching and adhesive application automated production line also includes a waste placement station 23, which is also located within the sliding path of the electric slide rail 2. The upper gripping mechanism 3 also includes a secondary negative pressure rod 24 and a secondary negative pressure head 25. The upper gripping mechanism 3 is fixed with the secondary negative pressure rod 24, which is parallel to the main negative pressure rod 20 and connected to the negative pressure device through a pipe to achieve a controllable negative pressure effect. The bottom of the secondary negative pressure rod 24 is fixedly connected to the secondary negative pressure head 25 made of rubber. The position of the secondary negative pressure head 25 where the upper gripping mechanism 3 is located is higher than the positions of each main negative pressure head 21. The top of the lower mold 9 has a receiving groove 26 for receiving waste. When the discharge port 10 is vertically aligned with the main negative pressure rod 20 of the upper gripping mechanism 3, the receiving groove 26 is vertically aligned with the secondary negative pressure rod 24.

[0027] Furthermore, before the ultrasonic punching machine 1 punches the raw material, the lower gripping mechanism 4 controls its main negative pressure head 21 to move upward and insert into the discharge port 10 to perform negative pressure gripping on the product part of the raw material on the lower die 9. After punching is completed, the waste product falls into the receiving groove 26. The lower gripping mechanism 4 controls the gripper 18 to move downward appropriately to wait for the main negative pressure head 21 of the upper gripping mechanism 3 to perform negative pressure gripping. When the gripper 18 of the upper gripping mechanism 3 performs negative pressure gripping on the punched product, the auxiliary negative pressure head 25 can be used to adsorb the waste product at the same time. Since there is a height difference between the auxiliary negative pressure head 25 and the main negative pressure head 21, the waste product is on top and the product is on the bottom. Then the electric slide rail 2 drives the upper gripping mechanism 3 to move. The upper gripping mechanism 3 first applies adhesive to the product, then places the product in the finished product placement station 6, and then places the waste product in the waste product placement station 23. In this way, the waste product is automatically cleaned, and the degree of automation and processing efficiency are higher.

[0028] The above description represents a preferred embodiment of the present invention. For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of the present invention, based on the teachings of the present invention, still fall within the protection scope of the present invention.
