Description

Resistance element testing device Technical Field

[0001] This application relates to the field of resistor detection technology, and in particular to a resistor detection device. Background Technology

[0002] As a key component in electronic circuits, the stability of resistor performance directly affects the operation of the entire circuit. In modern electronics manufacturing, quality inspection of resistors is a crucial step in ensuring product quality.

[0003] In the industry, it's common practice for workers to manually connect resistors to testing instruments for individual testing. When testing a resistor, the worker holds two test pens on the instrument and touches them to both ends of the resistor to perform the test. While this method is simple and direct, it's time-consuming and labor-intensive. Summary of the Invention

[0004] To improve the efficiency of resistance sheet detection, this application provides a resistance sheet detection device.

[0005] The resistor element detection device provided in this application adopts the following technical solution:

[0006] A resistor sheet testing device includes a worktable and a vibratory feeder disposed on one side of the worktable. A testing machine and a testing platform are fixedly mounted on the top side of the worktable. A material distribution mechanism and a support platform are fixedly mounted on the top side of the testing platform. A placement block, a first cylinder, and a robotic arm are fixedly mounted on the top side of the support platform. A push block is fixedly mounted on the piston rod of the first cylinder. A first receiving groove is opened on the top side of the placement block for the push block to enter. The first cylinder is used to push the push block to slide along the first receiving groove. The robotic arm is used to place the resistor sheet from the vibratory feeder into the first receiving groove. An energizing mechanism is installed on the placement block to connect the resistor sheet to the testing machine. The testing machine is used to test the resistor sheet. A material guide channel is fixedly mounted on the end of the support platform away from the first cylinder. The material guide channel is used to feed the resistor sheet into the material distribution mechanism. Multiple receiving boxes are placed on the top side of the worktable, and the material distribution mechanism is used to feed the resistor sheet into the receiving boxes.

[0007] By adopting the above technical solution, the robotic arm places the resistance sheet from the vibratory feeder into the first receiving slot. Combined with the first cylinder pushing the pusher block to slide along the first receiving slot, the robotic arm can stably position and transport the resistance sheet. The energizing mechanism connects the resistance sheet to the testing machine, enabling the testing machine to automatically complete the testing of the resistance sheet's resistance value, continuity, and other performance characteristics, avoiding the tedious manual testing operations. The feeding channel sends the tested resistance sheets to the sorting mechanism, which classifies the resistance sheets according to the test results and sends them to different receiving boxes, realizing integrated testing and sorting operations, thereby improving work efficiency.

[0008] Optionally, a second receiving groove is provided on both inner sidewalls of the first receiving groove. The second receiving groove is used to allow one side of the resistor sheet to enter. A support groove and a feed inlet are fixedly installed on one side of the placement block. The inner bottom wall of the feed inlet is flush with the inner bottom wall of the support groove. The feed inlet is connected to the second receiving groove.

[0009] By adopting the above technical solution, the robot arm places the resistor sheet in the support groove. After the resistor sheet pushes against each other on the support groove, it enters the first and second receiving grooves from the feed port, thus facilitating the flat placement of the resistor sheet.

[0010] Optionally, a support frame is fixedly installed on the side of the placement block away from the support groove, and a first infrared sensor is fixedly installed on the support frame. A first clearance hole is opened on the top side of the placement block for the first infrared sensor to pass through, and the first clearance hole is connected to the second receiving groove.

[0011] By adopting the above technical solution, the first infrared sensor can detect whether a resistive element is placed in the second receiving slot, thereby realizing automated monitoring of the resistive element's position and improving detection efficiency and accuracy. The setting of the first clearance hole ensures that the first infrared sensor can accurately detect the resistive element in the second receiving slot.

[0012] Optionally, the energizing mechanism includes a mounting frame and an energizing assembly. The mounting frame is fixedly installed on the support platform and is located at the end of the placement block away from the first cylinder. The energizing assembly includes a second cylinder, a mounting base, and energizing rods. The cylinder body of the second cylinder is fixedly connected to the mounting frame, and the piston rod of the second cylinder is fixedly connected to the mounting base. The second cylinder extends and retracts along the height direction. The mounting base slides through the mounting frame. Each energizing assembly includes two energizing rods. The energizing rods are vertically fixedly installed on the mounting base. A second clearance hole is provided on the top side of the placement block to avoid the energizing rods. The second clearance hole communicates with the second receiving groove.

[0013] By adopting the above technical solution, the mounting bracket provides a stable installation position for the energized component, ensuring its precise operation. The second cylinder drives the mounting base to extend and retract along the height direction, causing the energizing rod to be precisely inserted into both ends of the resistor element, realizing automatic energization of the resistor element. The design of the energizing rod and the second clearance hole avoids interference between the energizing rod and the placement block during the movement, ensuring the smooth progress of the energizing process.

[0014] Optionally, there are two power-conducting components, one of which is fixedly installed on the top side of the mounting bracket, and the other is fixedly installed on the bottom side of the mounting bracket.

[0015] By adopting the above technical solution, and setting two power-conducting components located on the top and bottom sides of the mounting bracket respectively, it is possible to ensure that the two ends of the resistance element are stably connected to the testing machine, thereby improving the accuracy and reliability of the test.

[0016] Optionally, the material distribution mechanism includes a mounting frame, a material distribution plate, a third cylinder, a rotating shaft, and a connecting block. The mounting frame is fixedly installed on the top side of the testing platform and is located above the receiving box. The material distribution plate is located inside the mounting frame. The rotating shaft is fixedly installed on the material distribution plate, and the end of the rotating shaft rotatably passes through the side wall of the mounting frame. The connecting block is fixedly installed on one end of the rotating shaft. The cylinder body of the third cylinder is hinged to the mounting frame, and the piston rod of the third cylinder is hinged to the connecting block.

[0017] By adopting the above technical solution, the mounting frame serves as a support structure, ensuring the stable rotation of the material distribution plate under the drive of the third cylinder. The third cylinder is connected to the rotating shaft via a connecting block, driving the material distribution plate to rotate around the rotating shaft, thereby accurately feeding the resistive elements into different receiving boxes based on the detection results.

[0018] Optionally, a storage plate is abutted against the discharge end of the vibratory feeder, a storage trough is formed on the storage plate, the resistive elements are arranged sequentially inside the storage trough, and a support base is fixedly installed between the storage plate and the testing table.

[0019] By adopting the above technical solution, the discharge end of the vibratory feeder is set to abut against the storage plate, allowing the resistance sheets to enter the storage tank in an orderly manner and arrange themselves sequentially inside the storage tank. This effectively avoids the resistance sheets becoming disordered or piling up during transmission, improving the efficiency and accuracy of subsequent testing. The storage plate temporarily stores the resistance sheets, making it convenient for the robotic arm to remove them.

[0020] Optionally, two second infrared sensors are embedded in the inner bottom wall of the storage tank.

[0021] By adopting the above technical solution, the two second infrared sensors embedded in the bottom wall of the storage tank can detect the number of resistors in the storage tank in real time, ensuring that the vibratory feeder is started in time when the number of resistors is insufficient or the vibratory feeder is turned off in time when the number is sufficient, thereby improving detection efficiency and reducing manual intervention.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] By coordinating a vibratory feeder, a robotic arm, a first cylinder, and an energizing mechanism, the automatic feeding, positioning, and testing of resistance elements are achieved, significantly improving testing efficiency, reducing manual intervention, and enhancing the consistency and accuracy of testing.

[0024] The sorting mechanism automatically classifies the resistor sheets according to the test results and sends them into the corresponding receiving boxes, realizing automated sorting and processing after testing, reducing the complexity of manual operation, and improving overall work efficiency.

[0033] The present application will be further described in detail below with reference to Figures 1-7.

[0034] This application discloses a resistor detection device.

[0035] Referring to Figure 1, the resistor sheet testing device includes a worktable 1 and a vibratory feeder 2 disposed on one side of the worktable 1. A storage plate 3 is abutted against the discharge end of the vibratory feeder 2, and a storage trough 4 is formed on the storage plate 3. A testing machine 5 and a testing table 6 are fixedly installed on the top side of the worktable 1, and a support base 7 is fixedly installed between the storage plate 3 and the testing table 6.

[0036] The resistance sheet is placed inside the vibratory feeder 2, and the testing machine 5 starts the vibratory feeder 2. The vibratory feeder 2 feeds the resistance sheet one by one into the storage tank 4, so that the resistance sheet is arranged in sequence inside the storage tank 4.

[0037] Referring to Figure 2, two second infrared sensors 9 are embedded in the inner bottom wall of the storage tank 4. When the resistive sheet inside the storage tank 4 covers the two second infrared sensors 9, the detection machine 5 shuts off the vibratory feeder 2, thereby stopping the feeding of the resistive sheet into the storage tank 4. When neither of the two second infrared sensors 9 is blocked by the resistive sheet, the detection machine 5 starts the vibratory feeder 2, thereby beginning to feed the resistive sheet into the storage tank 4.

[0038] Referring to Figures 3 and 4, a support platform 10 is fixedly installed on the top side of the testing platform 6. A placement block 11, a first cylinder 12, and a robotic arm 13 are fixedly installed on the top side of the support platform 10. A push block 14 is fixedly installed on the piston rod of the first cylinder 12.

[0039] Referring to Figures 4 and 5, a first receiving groove 15 is provided on the top side of the placement block 11 for the push block 14 to enter. A first cylinder 12 is used to push the push block 14 to slide along the first receiving groove 15. Second receiving grooves 16 are provided on both inner side walls of the first receiving groove 15, for one side of the resistor sheet to enter. A support groove 18 and a feed inlet 17 are fixedly installed on one side of the placement block 11. The inner bottom wall of the feed inlet 17 is flush with the inner bottom wall of the support groove 18, and the feed inlet 17 communicates with the second receiving grooves 16.

[0040] A support frame 19 is fixedly installed on the side of the placement block 11 away from the support groove 18, and a first infrared sensor 8 is fixedly installed on the support frame 19. A first clearance hole 20 is opened on the top side of the placement block 11 for the first infrared sensor 8 to pass through, and the first clearance hole 20 is connected to the second receiving groove 16.

[0041] The robotic arm 13 removes the resistor sheet from the storage tank 4 and places it into the support tank 18. After the resistor sheets push against each other inside the support tank 18, the resistor sheet enters the first receiving tank 15 and the second receiving tank 16 from the feed port 17, thus facilitating the flat placement of the resistor sheet.

[0042] After the resistive element enters the first receiving groove 15 and the second receiving groove 16, the first infrared sensor 8 is blocked by the resistive element, and the detection machine 5 activates the first cylinder 12. The first cylinder 12 pushes the resistive element to slide inside the first receiving groove 15.

[0043] Referring to Figures 4 and 6, the placement block 11 is provided with an energizing mechanism 22. The energizing mechanism 22 includes a mounting bracket 221 and an energizing component 222. The mounting bracket 221 is fixedly mounted on the support platform 10 and is located at the end of the placement block 11 away from the first cylinder 12. There are two energizing components 222: one is fixedly mounted on the top side of the mounting bracket 221, and the other is fixedly mounted on the bottom side of the mounting bracket 221.

[0044] The energizing assembly 222 includes a second cylinder 2221, a mounting base 2222, and energizing rods 2223. The cylinder body of the second cylinder 2221 is fixedly connected to the mounting bracket 221. The piston rod of the second cylinder 2221 is fixedly connected to the mounting base 2222, and the second cylinder 2221 extends and retracts along the height direction. The mounting base 2222 slides through the mounting bracket 221. Each energizing assembly 222 includes two energizing rods 2223. The energizing rods 2223 are vertically fixedly installed on the mounting base 2222. A second clearance hole 21 for avoiding the energizing rods 2223 is provided on the top side of the placement block 11. The second clearance hole 21 communicates with the second receiving groove 16.

[0045] The first cylinder 12 pushes the resistance sheet into the first receiving groove 15 and slides it into the energizing mechanism 22, then stops. The testing machine 5 then activates the second cylinder 2221, causing the energizing rod 2223 to contact the resistance sheet for testing. By using two energizing components 222 to test the resistance sheet, it helps ensure that the testing machine 5 is connected to the resistance sheet.

[0046] Referring to Figures 1, 2, and 7, a material distribution mechanism 23 is also fixedly installed on the top side of the testing platform 6, and a material guide channel 24 is fixedly installed at the end of the support platform 10 away from the first cylinder 12. After the testing machine 5 tests the resistance sheet through the energizing mechanism 22, the first cylinder 12 is restarted, thereby pushing the resistance sheet into the material guide channel 24. The resistance sheet slides along the material guide channel 24 towards the material distribution mechanism 23. After the resistance sheet enters the material distribution mechanism 23, the first cylinder 12 resets.

[0047] Multiple receiving bins 25 are placed on the top side of the workbench 1. The material distribution mechanism 23 includes a mounting frame 231, a distribution plate 232, a third cylinder 233, a rotating shaft 234, and a connecting block 235. The mounting frame 231 is fixedly mounted on the top side of the inspection table 6. The mounting frame 231 is located above the receiving bins 25, and the distribution plate 232 is located inside the mounting frame 231. The rotating shaft 234 is fixedly mounted on the distribution plate 232, and its end rotates through the side wall of the mounting frame 231. The connecting block 235 is fixedly mounted on one end of the rotating shaft 234. The cylinder body of the third cylinder 233 is hinged to the mounting frame 231, and the piston rod of the third cylinder 233 is hinged to the connecting block 235.

[0048] After the resistance element is tested under power, the testing machine 5 determines its performance and which receiving bin 25 it should be placed in. Then, the testing machine 5 activates the third cylinder 233, which extends and retracts to push the connecting block 235. The connecting block 235 drives the rotating shaft 234 to rotate, which in turn drives the distributing plate 232 to rotate. The distributing plate 232 guides the resistance element into the corresponding receiving bin 25.

[0049] In this embodiment, there is only one mounting frame 231, two material distribution plates 232, two third cylinders 233, two rotating shafts 234, and two connecting blocks 235, and three receiving boxes 25. By using the different rotation angles of the two material distribution plates 232, it is convenient to select one of the three receiving boxes 25 to receive the resistor sheet.

[0050] The implementation principle of the resistor detection device in this embodiment is as follows: The vibratory feeder 2 is activated, and it feeds the resistor into the storage tank 4. The robotic arm 13 removes the resistor from the storage tank 4 and places it into the support tank 18. Inside the support tank 18, the resistors are pressed together and then enter the first receiving tank 15 and the second receiving tank 16 through the feed inlet 17. Then, the first cylinder 12 pushes the pusher block 14 to slide along the first receiving tank 15, pushing the resistor towards the energizing mechanism 22. The energizing mechanism 22 connects the resistor to the detection machine 5, thereby detecting the resistor.

[0051] After the resistor sheet is tested, the testing machine 5 determines the receiving bin 25 to be placed in based on the resistor sheet's performance. Then, the testing machine 5 controls the dispensing mechanism 23 to send the resistor sheet into the corresponding receiving bin 25, thereby improving the testing efficiency of the resistor sheet.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
