Description

Technical Field

[0001] The invention relates to a nickel mesh spraying production line, in particular to an automatic nickel mesh spraying line and an operating process method thereof, belonging to the technical field of nickel mesh spraying. Background Art

[0002] Nickel mesh is a metal mesh with excellent corrosion resistance, electrical conductivity and thermal conductivity, and is widely used in the field of water electrolysis hydrogen production. At present, with the improvement of hydrogen production technology, the development trend of hydrogen energy is gradually increasing, and the demand for nickel mesh electrodes in water electrolysis hydrogen production equipment is also gradually increasing.

[0003] Nickel mesh cannot be used directly for electrolytic hydrogen production. A porous Raney nickel powder catalyst needs to be sprayed on the surface of the nickel mesh to achieve efficient electrolytic hydrogen production. Currently, all nickel mesh spraying production processes rely on manual labor, which increases the intensity of manual labor, reduces production efficiency, and is more expensive.

[0004] In addition, due to the soft, thin and porous properties of nickel mesh, the conventional robots and water conveying devices on the market cannot achieve automated production, and it is particularly difficult to establish an automated production line, which brings unfavorable factors to the quantitative production of nickel mesh electrodes.

[0005] The use of automated production lines presents technical problems such as how to ensure the flatness of the nickel mesh before spraying during the transfer process and the bonding integrity of the nickel mesh surface coating after spraying. Conventional suction cups and holding devices on the market: first, they cannot lift and transfer the nickel mesh as a whole; second, they can lift and transfer but will damage the surface coating of the nickel mesh after spraying, greatly reducing the qualified rate of the finished product. Summary of the invention

[0006] The technical problem to be solved by the present invention is: to provide a nickel mesh spraying automation line and its operating process method. In view of the special properties of the nickel mesh material, a manipulator with reasonable design, high production efficiency and low failure rate and a tooling fixture for spraying production and processing are used to form an automated production line. The manipulator device is composed of the most widely used materials and accessories on the market. The manipulator is controlled by PLC, and the signal output of various sensors is used to control the movement of the manipulator and the execution of various actions. The design is optimized based on the existing tooling, and the spraying tooling required for production is highly matched with the manipulator to realize the automated production of the nickel mesh spraying process, reduce the labor intensity of manpower, and improve production efficiency.

[0007] The technical solution adopted by the present invention to solve the technical problem is as follows:

[0008] A nickel mesh spraying automation line, comprising a sandblasting to spraying robot, spraying station No. 1, spraying station No. 2, spraying station No. 3, a sandblasting loading station, a sandblasting loading robot, a material station to be sandblasted, an operator assembly station, a material station to be disassembled of a finished sprayed product, a sandblasting station, a temporary storage station after sandblasting, a temporary storage station for finished sprayed products, a spraying tool, a material transport trolley and a trolley fixing device. The sandblasting to spraying robot and the sandblasting loading robot both comprise a robot carrier, an X-axis hard limit, an X-axis soft limit, a rack, a slider rail, a robot actuator, a Z-axis moving module, a Y-axis servo motor, an X-axis servo motor, an X-axis moving module, a Y-axis moving module and a reducer. The motion structures of the X-axis, Y-axis and Z-axis of the sandblasting to spraying robot or the sandblasting loading robot are gear rack structures, which are controlled by the X-axis servo motor, the Y-axis servo motor and the Z-axis servo motor respectively.

[0009] The manipulator actuator of the sandblasting feeding manipulator includes an aluminum profile frame Ⅰ and a manipulator actuator unit Ⅰ. The manipulator actuator unit Ⅰ includes a slider Ⅰ, a gripper Ⅰ, a sensor Ⅰ, a connecting rod Ⅰ and a stroke cylinder Ⅰ. The sensor Ⅰ controls the air intake and exhaust of the stroke cylinder Ⅰ. The slider Ⅰ is connected to the action part of the stroke cylinder Ⅰ through the connecting rod Ⅰ. The gripper Ⅰ is fixed on the upper end of the slider. The stroke cylinder Ⅰ extends and contracts to drive the gripper Ⅰ. The gripper Ⅰ hooks the manipulator extraction handle on the material tooling to extract the material.

[0010] The manipulator actuator of the sandblasting to spraying manipulator includes an aluminum profile frame II, a manipulator actuator unit II and 4 electromagnets. The electromagnet is used to grab the tooling pressure ring during spraying. The manipulator actuator unit II includes a stroke cylinder II, a connecting rod II, a slider II, a sensor II and a gripper II. The sensor II controls the air intake and exhaust of the stroke cylinder II. The slider II is connected to the action part of the stroke cylinder II through the connecting rod II. The gripper II is fixed at the upper end of the slider II. The stroke cylinder II extends and contracts to drive the gripper II. The gripper II hooks the manipulator extraction handle on the material tooling to extract the material.

[0011] The spraying tooling comprises a nickel mesh grid frame tray, a tooling pressure ring and a manipulator extraction handle. The nickel mesh grid frame tray is provided with a manipulator extraction handle around it and a notch at the bottom to facilitate stacking of multiple nickel mesh grid frame trays.

[0012] The material transport trolley comprises a trolley frame body, vertical baffles and moving wheels. The vertical baffles are arranged around the trolley frame body to ensure the stability and position of the material when it moves up and down.

[0013] The trolley fixing device includes a U-shaped card plate, a rotating baffle, a baffle fixing groove, a fixing cylinder, a fixing base, a handle and a rotating shaft. Two baffle fixing grooves are symmetrically arranged on the upper end of the fixing cylinder. The U-shaped card plate is located at the front end of the rotating baffle and is used to fix the support rod at the lower end of the trolley frame body. The fixing cylinder is fixedly welded to the fixing base, and the handle is located at the top of the rotating shaft. When the trolley fixing device is not in use, the rotating baffle is wrapped around the rotating shaft, and the baffles on both sides of the U-shaped card groove are stuck in the two baffle fixing grooves.

[0014] The X-axes of the sandblasting to spraying robot and the sandblasting feeding robot both adopt double servo motors, racks and sliding modules, and the Y-axes and Z-axes both adopt single servo motors and transmission sliding modules.

[0015] The operating process of the nickel mesh spraying automation line body comprises the following steps:

[0016] A. Preparation: Since spraying requires tooling clamping, the nickel mesh spraying tooling needs to be assembled manually, placed on the material transport cart and pushed to the loading station of the sandblasting manipulator. The specific operation process is: place a nickel mesh frame tray on the corresponding workbench → take a nickel mesh to be sprayed and place it on the nickel mesh frame tray → place the completed spraying tooling on the material transport cart → repeat the above operation → stack several nickel mesh frame trays with nickel mesh through the lower notch and place them on the material transport cart → push the material transport cart to the sandblasting loading station after it is stacked full → use 4 cart fixing devices to fix the material transport cart to prevent the material transport cart from moving back and forth;

[0017] B. Sand blasting:

[0018] (1) Manually push the material transport cart full of materials to be sandblasted to the loading station to be sandblasted, then fix the material transport cart through the cart fixing device, start the sandblasting loading robot, and the sandblasting loading robot moves to the loading station to be sandblasted after receiving the incoming material signal; the Z-axis servo motor drives the robot actuator to move downward, and after the sensor detects the material, the slider is connected to the action part of the stroke cylinder through the connecting rod, and the claw is fixed to the upper end of the slider. The stroke cylinder extends and retracts to drive the claw, and the claw hooks the robot extraction handle on the material tooling to extract the material; the Z-axis servo motor drives the robot actuator to lift the material upward and transport it to the entrance of the sandblasting machine, and place the material on the conveyor belt of the sandblasting machine. After returning, take out another material to be sandblasted and wait at the entrance of the sandblasting machine;

[0019] (2) After the robot receives the signal that the previous material has reached the corresponding position, the sensor receives the material signal and feeds it back to the sandblasting feeding robot waiting at the entrance of the sandblasting machine. When the sandblasting feeding robot receives the signal, it promptly places the material at the entrance of the sandblasting machine, and returns to the sandblasting feeding station to grab the material and move it to the entrance of the sandblasting machine to wait, and the cycle is repeated;

[0020] (3) When the sensor at the outlet of the sandblasting machine receives the material, the sandblasting machine stops working, and when the material received at the outlet of the sandblasting machine is taken away by the robot, the sandblasting machine starts working;

[0021] (4) When the material on the sandblasting loading station is running out, the machine indicator light flashes and the buzzer alarm reminds the staff to replenish the material, and the cycle is repeated;

[0022] C. Spraying:

[0023] (1) From sandblasting to spraying, the robot takes the sandblasted material and places it on the spraying station No. 1 on the spraying exchange platform. At the same time, the electromagnet is energized to place the tooling pressure ring on the material, and the spraying station No. 1 enters the spraying area and starts spraying;

[0024] (2) After the sandblasting robot places the material on the spraying platform, it returns to the sandblasting machine exit to take the sandblasted material and wait in the waiting area;

[0025] (3) When receiving the signal that spraying is about to be completed from spraying station No. 1, the spraying robot goes to the spraying platform and places the material to be sprayed on spraying station No. 2. After spraying station No. 1 is exchanged, the finished sprayed material is taken away and placed on the temporary storage station for finished sprayed products, and then returns to the sandblasting machine outlet to take the finished material after sandblasting; if no signal is received that spraying is about to be completed from the spraying station, when receiving the signal that there is material at the sandblasting machine outlet, the robot first places the finished material after sandblasting on the temporary storage station after sandblasting, and then takes the material at the sandblasting outlet to ensure the continuous operation of the sandblasting machine, and repeats the cycle;

[0026] (4) When the amount of materials on the spray finished product storage station reaches a certain level, the machine indicator light flashes and the buzzer alarm prompts the staff to push the full cart away and replace it with a new one, and the cycle is repeated.

[0027] The structures not disclosed in the present invention are all prior art. The present invention is an improvement and innovation based on the prior art, has outstanding substantive features and significant progress, and is non-obvious.

[0028] The positive beneficial effects of the present invention are as follows:

[0029] 1. The nickel mesh spraying automation line of the present invention includes two parts: the pre-sandblasting feeding process and the sandblasting to spraying process. Both parts use a truss manipulator solution, which consists of a sandblasting feeding manipulator, a sandblasting to spraying transfer manipulator, a spraying tooling, a logistics transport trolley and a trolley fixing device. The sandblasting feeding manipulator and the sandblasting to spraying transfer manipulator are both composed of a manipulator actuator and a mobile carrier. The mobile carrier is built with a rectangular square tube, and slider guides and transmission racks are laid parallel on both sides. The manipulator actuator frame is made of aluminum profiles, and the action execution components are composed of a stroke cylinder, a sliding module, a lifting claw, a sensor and an electromagnet; the manipulator X-axis uses a dual servo motor, a rack and a sliding module, and the Y-axis and Z-axis both use a single motor and a transmission sliding module. This structure is simple and convenient to maintain and replace. The manipulator moves when signals are sent from different workstations. The manipulator moves to different workstations to perform different actions. The actuator is the extension and contraction of the stroke cylinder, which drives the slider to move through the connecting rod to indirectly open and close the gripper, and move the nickel mesh. The logistics transport trolley can be used as a transfer vehicle or as a loading platform for automatic loading and unloading. It is more convenient to use it in combination. The logistics transport trolley is designed with vertical baffles around it to facilitate the positioning and stability of materials. At the same time, there are temporary storage areas for finished spraying products and temporary storage areas after sandblasting between the workstations. The temporary storage area for finished spraying products can store a certain number of finished products. After a certain number, the operator will pull them out, reducing the frequency of operators collecting finished products and making full use of working time.

[0030] 2. In view of the special properties of nickel mesh materials, the present invention adopts a manipulator with reasonable design, high production efficiency and low failure rate and a tooling fixture for spraying production and processing to form an automated production line. The manipulator device is composed of the most widely used materials and accessories on the market. The manipulator is controlled by PLC (which is a prior art and not reflected in this article), and the signal output of various sensors is used to control the movement of the manipulator and the execution of various actions. It is optimized and designed based on the existing tooling, and the spraying tooling required for production is highly matched with the manipulator to realize the automated production of the nickel mesh spraying process, reduce manual labor intensity, and improve production efficiency.

[0031] 3. The present invention provides an automatic nickel mesh spraying line for the nickel mesh, which is soft, thin and porous. By setting up a spraying tool, the nickel mesh and the manipulator are in indirect contact. By setting up a material transport trolley, the transfer and transportation between the various processes of the nickel mesh spraying process can be achieved.

[0032] 4. The present invention solves the problem of all manual operations from sandblasting to spraying, and a set of sandblasting system can be equipped with less than 3 sets (including 3 sets) of spraying stations, which truly reduces the labor intensity of workers and effectively improves production efficiency.

[0033] 5. The present invention solves the uncertainty caused by manual operation in the production process from sandblasting to spraying, ensures the stability of the production process of the entire process, and thus improves the consistency of the product.

[0034] 6. The present invention solves the problems of mass production and high labor cost for nickel mesh electrode manufacturers, thereby reducing the production costs of enterprises. BRIEF DESCRIPTION OF THE DRAWINGS

The logistics transport trolley can be used as a transfer vehicle or as a loading platform for automatic loading and unloading. It is more convenient to use it in combination. The logistics transport trolley is designed with vertical baffles around it to facilitate the positioning and stability of materials. At the same time, there are temporary storage areas for finished spraying products and temporary storage areas after sandblasting between the workstations. The temporary storage area for finished spraying products can store a certain number of finished products. After a certain number, the operator will pull them out, reducing the frequency of operators collecting finished products and making full use of working time.

The manipulator device is composed of the most widely used materials and accessories on the market. The manipulator is controlled by PLC (which is a prior art and not reflected in this article), and the signal output of various sensors is used to control the movement of the manipulator and the execution of various actions.
