Description

Technical Field

[0001] The invention belongs to the technical field of defective product counting, and in particular relates to a limit response counter for defective product of a production line piston. Background Art

[0002] Defective products refer to raw materials, semi-finished products, and finished products that do not meet relevant quality requirements during production and manufacturing. Quality requirements can be inspection quality requirements, manufacturing process quality requirements, customer quality requirements, national laws and regulations, etc.

[0003] The piston is the "heart" of the automobile engine. It bears alternating mechanical and thermal loads and is one of the key components in the engine with the worst working conditions. The function of the piston is to withstand gas pressure and transmit it to the connecting rod through the piston pin to drive the crankshaft to rotate. The top of the piston is also a component of the combustion chamber. On the production line of pistons, it is inevitable that pistons with substandard quality levels will appear. In order to prevent unqualified pistons from flowing into the next production process, production line employees need to conduct quality inspections on the pistons. Severely defective and defective products need to be placed in special storage boxes and handled separately. However, in the actual production process, such a situation may occur. In a production batch, the number of severely defective products has exceeded the predetermined defective product limit response number, but it is difficult for production line employees to detect the potential problems of the production line in time, resulting in a higher frequency of defective products, affecting production efficiency and causing economic losses. Summary of the invention

[0004] The purpose of the present invention is to provide a counter that can monitor the number of defective parts such as pistons on an assembly line in real time. In particular, when the number of defective products reaches a predetermined limit response number, an alarm can be issued to remind the assembly line operators to conduct quality inspections and screenings in a timely manner to prevent defective products from further flowing into the next process, thereby improving production efficiency, reducing resource waste and quality problems in the production process, and ultimately ensuring the stable operation of the production line and product quality.

[0005] To achieve the above object, the present invention provides the following technical solution: a pipeline piston defective product limit response counter, comprising:

[0006] Cabinet structure: The counter consists of a cabinet, which is connected to the cabinet door by hinges for easy opening and closing. The cabinet door is equipped with a cabinet lock to ensure the safe storage of items in the cabinet. The design of the cabinet is to ensure that all functional components can be efficiently integrated and easy to maintain and operate.

[0007] Counting and warning system: The counter is equipped with an LED digital tube display screen, which can display the number of defective products in real time, making it convenient for operators to monitor the number of defective products on the assembly line. The LED digital tube is controlled by the power switch, and is equipped with a power indicator to indicate the working status of the system. The counter also includes a warning light and a buzzer. When the number of defective products reaches the set limit, these warning devices will automatically start to remind the operator to take timely measures to avoid the accumulation of defective products and their flow into the next process.

[0008] Photoelectric switch and control button: The counter is equipped with a photoelectric switch, which is mainly used to identify and count the number of seriously defective products placed in the cabinet. Users can set the limit response number of defective products according to production needs through the increase limit value button and decrease limit value button on the outside of the cabinet. When the number of seriously defective products placed reaches the preset value, the system will trigger an alarm and update the number of defective products in real time on the LED digital tube.

[0009] Circuit board design: All control components (including LED digital tube, power switch, power indicator light, warning light, buzzer, photoelectric switch, limit value increase button and limit value decrease button) are connected by the same circuit board, which is installed inside the cabinet to ensure stable system operation and facilitate subsequent maintenance and upgrades.

[0010] Cabinet lock design: In order to ensure the safety of the cabinet door and facilitate operation, the cabinet lock adopts a simple and effective design. The cabinet lock consists of six parts: the cabinet lock base, movable pawl, bolt, washer, nut and cabinet lock control rod. When the cabinet lock control rod passes the head of the movable pawl, it can drive the pawl to rise, so that the cabinet lock control rod passes through the cabinet lock base and the movable pawl. When the cabinet lock control rod reaches the middle of the pawl, the pawl is used to close and lock the cabinet door. The cabinet lock can lock and open the cabinet door by simply moving the cabinet lock control rod back and forth. This design is not only simple but also efficient, reducing the use of traditional complex cabinet lock structures and ensuring convenient opening and closing of cabinet doors.

[0011] Preferably, the power switch control system of the counter not only ensures that the device can start normally, but also has a power indicator light to reflect the switch status of the device in real time. In order to avoid the device being in standby mode for a long time, the system design uses an automatic power-off function to improve energy utilization efficiency.

[0012] Preferably, the LED digital tube adopts a high brightness design, which can clearly display the real-time number of defective products under various lighting conditions. The update frequency of the digital tube matches the recognition accuracy of the photoelectric switch, ensuring that the number can be updated quickly and accurately after each defective product enters the counting system. The operator can understand the number of defective products on the production line at a glance through the digital tube, so as to take necessary adjustment measures.

[0013] Preferably, the limit value increase button and limit value decrease button are connected to the internal circuit, allowing the operator to adjust the limit response number of defective products in real time according to production needs. This design supports the flexibility and precise control of the production line and helps to make dynamic adjustments according to different production batches and quality standards.

[0014] Preferably, when the number of defective products reaches the set limit, the counter will sound an alarm through a warning light and a buzzer at the same time. The warning light can be designed to flash so that it can be clearly seen in any environment; the buzzer can be designed to have a high frequency to ensure that the operator can receive the alarm information in time and conduct quality inspection quickly even in a noisy production environment.

[0015] Preferably, in order to facilitate classification and sorting, multiple partitions are designed inside the cabinet, and the left cabinet is specially used to store seriously defective products. There are labels above each area, clearly marking "seriously defective products" or "defective products", so that staff can quickly classify according to quality standards and take corresponding treatment measures for different levels of defective products.

[0016] The beneficial effects of the present invention are:

[0017] Timely detection and processing of defective products: The counter monitors the number of defective products in real time during the assembly line operation and issues alarms in a timely manner, effectively avoiding the backlog of defective products and reducing the economic losses caused by product quality problems.

[0018] Improve production efficiency: Through automatic counting and real-time alarm, the time for manual counting and visual inspection is reduced, the production efficiency is improved, and the smooth progress of assembly line operations is ensured.

[0019] Easy and flexible operation: The defective product limit response number can be set by increasing and decreasing buttons, and the cabinet door lock is simple and efficient, making the equipment easy and fast to use and able to quickly adapt to the needs of different production batches.

[0020] Reliable security: The design of the cabinet lock ensures the safety of the equipment, prevents misoperation or accidental unlocking, and ensures that the items stored in the equipment are not taken away or disturbed at will. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Reference Figure 1 The present invention proposes a limit response counter for defective pistons of an assembly line. The basic structure of the counter includes a cabinet 1, which is connected to a cabinet door 2 through a hinge 4 for easy opening and closing. A cabinet lock 4 is installed in the middle of the cabinet door 2 to ensure the safety of items in the cabinet. The LED digital tube 5 is fixed on the top of the cabinet 1, and the digital tube display screen is embedded in the surface of the cabinet to display the number of defective products. Control buttons such as the power switch 6, the power indicator light 7, the warning light 8, the buzzer 9, the increase limit value button 11 and the decrease limit value button 12 are all embedded in the surface of the cabinet. The photoelectric switch 10 is embedded in the left side of the cabinet 1 and is responsible for counting the defective products placed in the cabinet.

[0031] When the user turns on the power switch 6, the power indicator light 7 will be always on, indicating that the counter is in working condition. The user can set the limit response number of defective products by increasing the limit value button 11 and decreasing the limit value button 12. To this end, the operator places the seriously defective products in the cabinet 1 and in the area of ​​the left cabinet 1 specially marked as "seriously defective products". The photoelectric switch 10 will count and record the number of seriously defective products put into the left cabinet in real time, and display the current count on the LED digital tube 5. Whenever the number of seriously defective products in the left cabinet reaches the set limit response number, the warning light 8 and the buzzer 9 will work at the same time, emitting an audible and visual alarm, prompting the assembly line operator to check the status of the production line in time to avoid further accumulation of the number of defective products, thereby improving production efficiency and avoiding the inconvenience and errors of manual counting.

The cabinet lock base 401 is fixed to the middle of the left cabinet door by welding, and the cabinet lock control rod 406 is welded to the middle of the right cabinet door. The working principle of the cabinet lock 4 is that when the cabinet lock control rod 406 passes through the head of the movable pawl 402, it can drive the pawl to rise, so that the cabinet lock control rod 406 passes through the cabinet lock base 401 and the movable pawl 402, thereby realizing the locking of the cabinet door 2. When the control rod 406 moves to the middle of the pawl, the action of the pawl makes the cabinet door 2 firmly closed, ensuring the safety of the cabinet door.

[0033] In the present invention, the cabinet lock 4 can lock and open the cabinet door 2 by simply moving the control rod 406 forward and backward, avoiding the design of a complex lock structure and reducing unnecessary structural complexity. This design effectively improves the ease of operation of the cabinet lock, and is particularly suitable for the need for rapid opening and closing in an assembly line operation environment. At the same time, this simplified design reduces functional waste and structural redundancy, and optimizes the operating experience of the entire counter device.

[0034] In summary, the embodiments of the present invention can realize real-time monitoring and management of the number of defective products in practical applications, especially in the process of assembly line production, which can effectively remind operators to take corresponding measures when the number of defective products reaches the set limit, thereby avoiding the continued production of defective products and ensuring the smooth operation of the production line.
