Description

Technical Field

[0001] This utility model relates to the field of resistance repair device technology, and in particular to a multi-cavity synchronous automatic feeding resistance repair device. Background Technology

[0002] A resistance tester can quickly and accurately measure the current resistance value of a product. This module feeds the measurement results back to the control system as a basis for resistance correction operations. For example, a resistance tester using a four-wire measurement method can effectively eliminate the influence of the test lead resistance and improve measurement accuracy.

[0003] In the production of electronic components, resistors require precise control of their resistance values. Current resistance testers still have certain limitations in practical applications. Although some resistance testers have the function of automatically pushing the test probes into contact with the product, it is difficult to ensure that the test probes maintain a tight contact with the product throughout the testing process. Once the test probes become loose, the contact resistance between the probes and the product changes, leading to deviations in the measured resistance values. This severely affects the accuracy of monitoring and may ultimately impact the quality stability and performance reliability of resistors. Utility Model Content

[0004] The purpose of this invention is to address certain limitations of existing resistance testers in practical applications. Although some resistance testers have the function of automatically pushing the test probe into contact with the product, it is difficult to ensure that the test probe remains in close contact with the product throughout the testing process. Once the test probe becomes loose, the contact resistance between the probe and the product changes, leading to deviations in the measured resistance value, seriously affecting the accuracy of monitoring, and ultimately potentially impacting the quality stability and performance reliability of resistive products.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: it includes a resistance meter, a robot is provided at the front end of the resistance meter, and a vibrating plate is connected to one side of the robot; The surface of the resistor is provided with multiple sets of resistance-correcting cavities at equal intervals. Each set of resistance-correcting cavities is provided with a pressure compensation component at its upper end. The pressure compensation component includes a lifting frame, a fixed frame connected to the front end of the lifting frame, sleeves connected to both sides of the fixed frame, and hand-tightening bolts inserted into the sleeves. The fixed frame is provided with threaded holes at the positions that match the two sets of hand-tightening bolts. A fixing block is connected to the top of the fixed frame, and a spring is provided inside the fixing block. A push plate is connected to the bottom of the spring, and test probes are connected to the four corners of the push plate.

[0006] Furthermore, the hand-tightening bolt passes through the sleeve and forms a threaded connection with the threaded hole, and the push plate and the spring form an elastic structure.

[0007] Furthermore, the four sets of test probes are connected to the fixing block in a sliding manner, and the outer surface of the push plate is in contact with the inner wall of the fixing block.

[0008] Furthermore, a collection and monitoring component is connected to one bottom side of the resistor, the collection and monitoring component includes a qualified compartment, and a handle is connected to the front end of the qualified compartment.

[0009] Furthermore, an alarm is connected to the qualified compartment at the lower end of the handle, and infrared sensors are connected to the inner walls on both sides of the alarm.

[0010] Furthermore, the infrared sensor and the alarm are electrically connected, and the qualified chamber and the resistance meter are slidably connected.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, after the robot places each group of products in the vibratory feeder into the resistance-correcting cavity, the resistor meter will automatically push the test probe closer to the surface of the product. The spring force achieves pressure compensation. The spring force can continuously act on the resistance test probe, ensuring that it is always in close contact with the product surface. Even if there are slight unevennesses on the product surface or slight vibrations occur during equipment operation, good contact can be guaranteed, thereby avoiding detection errors caused by loose contact and improving the accuracy of detection.

[0012] 2. In this utility model, after the resistance meter adjusts the resistance value of the product to the predetermined resistance range by using a milling cutter or machining method, it will automatically lower the product into the qualified bin for collection. The capacity inside the qualified bin can be monitored by an infrared sensor. When a large number of products are collected, the alarm will automatically sound under the action of the infrared sensor to remind the operator to clean up. Attached Figure Description

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Example 1, as Figure 1 - Figure 5 As shown, this utility model provides a multi-cavity synchronous automatic feeding and resistance-correcting device, including a resistance meter 1. A robot 2 is installed at the front end of the resistance meter 1, and a vibratory feeder 3 is connected to one side of the robot 2. Multiple sets of resistance-correcting cavities 4 are equidistantly arranged on the surface of the resistance meter 1. Each set of resistance-correcting cavities 4 has a pressure compensation component 5 at its upper end. The pressure compensation component 5 includes a lifting frame 501, a fixed frame 502 is connected to the front end of the lifting frame 501, and sleeves 503 are connected to both sides of the fixed frame 502. Hand-tightening bolts 504 are inserted into the inside of the sleeves 503. The fixed frame 502 and the two sets of hand-tightening bolts 504 are connected to each other. 04. Threaded holes 505 are provided at the matching positions. A fixing block 506 is connected to the top of the fixing bracket 502. A spring 507 is provided inside the fixing block 506. A push plate 508 is connected to the bottom of the spring 507. Test probes 509 are connected to the four corners of the push plate 508. The hand-tightening bolt 504 passes through the sleeve 503 and forms a threaded connection with the threaded hole 505. An elastic structure is formed between the push plate 508 and the spring 507. The four sets of test probes 509 are slidably connected to the fixing block 506. The outer surface of the push plate 508 is in contact with the inner wall of the fixing block 506.

[0018] The overall effect achieved by Example 1 is as follows: Production process: First, pour the product into the vibratory feeder 3 → Robot 2 picks up the product and places it in the resistance-correcting cavity 4 → Resistance meter 1 tests the product → Adjust the product resistance value using milling cutter or machining method to correct it to the specified resistance value range; at the same time, resistance meter 1 needs to monitor the product online → Materials with qualified resistance values ​​are automatically placed into the qualified warehouse 601, while products with qualified resistance values ​​do not need to be corrected. After the robot 2 places each group of products in the vibratory feeder 3 into the respective resistance-correcting cavities 4, the resistance meter 1 automatically pushes the test probe 509 closer to the product surface. When the test probe 509 contacts the product, it pushes the push plate 508 to compress the spring 507. After being compressed, the spring 507 achieves pressure compensation through its elasticity. The elasticity of the spring 507 can continuously act on the resistance test probe 509, ensuring that it always fits tightly against the product surface. At the same time, by turning the hand-tightening bolt 504, the entire fixing frame 502 can be disassembled, allowing for the replacement of the spring 507 and the test probe 509. In this way, even if there are minor unevennesses on the product surface or slight vibrations during equipment operation, good contact can be guaranteed, thereby avoiding detection errors caused by loose contact and improving the accuracy of detection.

[0019] Example 2, as Figure 1 and Figure 6 As shown, a collection and monitoring component 6 is connected to the bottom of one side of the resistor 1. The collection and monitoring component 6 includes a qualified compartment 601. A handle 602 is connected to the front end of the qualified compartment 601. An alarm 603 is connected to the lower end of the qualified compartment 601 and the inner walls on both sides of the alarm 603 are connected to infrared sensors 604. The infrared sensors 604 and the alarm 603 are electrically connected. The qualified compartment 601 and the resistor 1 are slidably connected.

[0020] The overall effect achieved by Example 2 is as follows: When the resistance meter 1 adjusts the resistance value of the product to the predetermined range using a milling cutter or machining method, it will automatically lower the product into the qualified bin 601 for collection. The infrared sensor 604 can monitor the internal capacity of the qualified bin 601. When a large number of products are collected, the infrared sensor 604 will sense the signal and send an electrical signal to the alarm 603, causing the alarm 603 to sound automatically and remind the operator to clean up.

[0021] Working principle: After robot 2 places each group of products in vibratory feeder 3 into resistance-correcting cavity 4, resistor meter 1 automatically pushes test probe 509 close to the product surface. The spring force 507 achieves pressure compensation. The spring force 507 can continuously act on the resistance test probe 509, ensuring it is always in close contact with the product surface. Even if there are minor unevenness on the product surface or slight vibration during equipment operation, good contact can be guaranteed, thus avoiding detection errors caused by loose contact and improving detection accuracy. After resistor meter 1 adjusts the product resistance value to the predetermined resistance range using milling cutter or machining, it will automatically lower the product into qualified bin 601 for collection. Infrared sensor 604 can monitor the internal capacity of qualified bin 601. When a large number of products are collected, alarm 603 will automatically sound under the action of infrared sensor 604 to remind the operator to clean up.

[0022] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
