Description

Technical Field

[0001] The invention relates to the technical field of concentrator detection equipment, in particular to a concentrator automatic key testing device. Background Art

[0002] A concentrator is a central connection point device that connects terminals, computers or communication equipment. It can become the central point where cables meet. Technically, a concentrator aggregates a certain number of input lines and a certain number of output lines, or provides a central communication link for many devices. There are many types of concentrator devices, most of which are used in the large computer world. In a number of terminal-intensive areas, in order to reduce communication lines, the terminal is usually connected to the concentrator first, and then the concentrator is connected to the computer's communication controller through a high-speed line. The concentrator is also an effective device for sharing lines and improving line utilization. It is mainly used to manage and transmit the data of the acquisition terminal in both directions, and can also perform data collection on the acquired data. It stores data in rows and exchanges data with the main station. It was originally designed to reduce the data transmission overhead of terminal devices that communicate with host devices through remote communication links. The multiplexer mixes data from multiple terminals into one link for transmission. The other end of the link has multiple decoders. There are many types of multiplexers: time division multiplexers allocate a time slot in the data stream to each device in turn, frequency division multiplexers provide multiple frequency band channels so that each device communicates with one channel, and concentrators are a special and most commonly used repeater. As the central node of network transmission, it overcomes the defect of a single medium path. It connects network nodes in a star topology.

[0003] A button is a device used to input information or control operations. The corresponding action or reaction is triggered by pressing or touching the button. The button usually has an identification or mark to indicate its corresponding function or operation. It can be a physical button, switch, etc., or a touch-sensitive button. The buttons on the concentrator are used to manually select and set the concentrator. It can query the data collected and stored by the concentrator, such as power data, power data, etc. The button detection equipment is a tool or device specifically used to detect the performance and function of the button. During the production process of the concentrator, the button detection equipment needs to be used to perform quality inspection on the buttons of the concentrator.

[0004] However, the existing processing equipment has the following shortcomings:

[0005] Existing key detection equipment detects the quality of keys by using a cylinder to drive a pressing contact to press the key, but the force during pressing is consistent, making it difficult to detect the state of the key under different pressing forces, resulting in inaccurate data detected by the equipment.

[0006] Therefore, we propose a concentrator automatic key test device to solve the above problems. Summary of the invention

[0007] The object of the present invention is to provide a concentrator automatic key test device. During the test, the key is placed on the slide plate, and the cylinder drives the telescopic rod to squeeze the pressing block to clamp the key between the pressing block and the second clamp. At this time, the pneumatic rod drives the assembly rod downward, and the assembly rod drives the first contact to press the key, and then the pneumatic rod drives the assembly rod to rise. At this time, the motor drives the gear to rotate, and the gear cooperates with the driving bar to drive the slide plate to move below the second contact. When the key corresponds to the bottom of the second contact, the pneumatic rod drives the assembly rod downward, and the second contact presses the key. Since the cylindrical contact under the second contact is longer than the cylindrical contact under the first contact, the pressing force of the second contact is heavier than that of the first contact. Then the pneumatic rod drives the assembly rod to rise again. At this time, the motor cooperates with the gear to drive the slide plate and the key to move below the third contact again, and then the pneumatic rod drives the assembly rod downward. At this time, the third contact and the key are pressed. Since the cylindrical contact under the third contact is longer than the cylindrical contact under the second contact, the pressing force of the third contact is heavier than that of the second contact, so as to solve the problems raised by the above background technology.

At this time, the button follows the slide plate to move to the left. When the button is against the baffle, the button stops moving. When the slide plate is completely reset, the button falls on the air cushion and follows the guidance of the guide plate away from the detection table. When the button falls on the air cushion, the guide plate is stressed, and the pressure spring generates elastic force to cooperate with the damper to buffer the force generated when the button falls, thereby reducing the situation that the button is broken and the appearance is bent. By setting the present invention, it is convenient to detect the performance of the button under different forces, evaluate the durability and stability of the button, and help to find possible problems with the button early, such as failures caused by uneven pressing force, adapt to the pressing force habits of different user groups, and improve the versatility and applicability of the product.

[0043] The effect achieved by the entire mechanism is as follows: by setting up the precise detection device 5, the auxiliary unloading device 6 and the component buffer device 7, during the detection, the key is placed on the slide plate 54, the cylinder 61 drives the telescopic rod 65 to squeeze the pressing block 63 to clamp the key between the pressing block 63 and the second clamp 64, at this time the pneumatic rod 3 drives the assembly rod 4 downward, the assembly rod 4 drives the first contact 51 to press the key, and then the pneumatic rod 3 drives the assembly rod 4 to rise, at this time the motor 57 drives the gear 58 to rotate, the gear 58 cooperates with the driving bar 59 to drive the slide plate 54 to move below the second contact 52, when the key corresponds to the bottom of the second contact 52, the pneumatic rod 3 drives the assembly rod 4 downward, the first contact 51 presses the key, and then the pneumatic rod 3 drives the assembly rod 4 to rise. The second contact 52 presses the button. Since the cylindrical contact under the second contact 52 is longer than the cylindrical contact under the first contact 51, the pressing force of the second contact 52 is heavier than that of the first contact 51. Then the pneumatic rod 3 drives the assembly rod 4 to rise again. At this time, the motor 57 cooperates with the gear 58 to drive the slide plate 54 and the button to move downward to the third contact 53 again. Then the pneumatic rod 3 drives the assembly rod 4 downward. At this time, the third contact 53 and the button are pressed. Since the cylindrical contact under the third contact 53 is longer than the cylindrical contact under the second contact 52, the pressing force of the third contact 53 is heavier than that of the second contact 52. At this time, the detection is completed, and then the cylinder 61 drives the telescopic rod 65 to The dynamic pressure block 63 is separated from the button, and the button loses its restraint. At this time, the driving machine 69 is started, and the driving machine 69 drives the threaded rod 67 to rotate. While the threaded rod 67 rotates, the thread drives the baffle 66 downward. At this time, the baffle 66 is located on the left side of the button. Then the motor 57 drives the gear 58 to reverse, and the slide plate 54 is reset. The slide plate 54 moves to the left. At this time, the button moves to the left with the slide plate 54. When the button hits the baffle 66, the button stops moving. When the slide plate 54 is completely reset, the button falls on the air cushion 72 and follows the guidance of the guide plate 71 away from the detection table 1. When the button falls on the air cushion 72, the guide plate 71 is stressed, and the pressure spring 75 generates elastic force to cooperate with the damper. 73 buffers the force generated when the key falls, reducing the situation where the key is broken and the appearance is bent. By setting up the present invention, it is convenient to detect the performance of the key under different forces, evaluate the durability and stability of the key, and help to discover possible problems with the key early, such as failures caused by uneven pressing force, adapt to the pressing force habits of different user groups, and improve the versatility and applicability of the product.
