Description

Technical Field

[0001] This utility model relates to the field of error-proofing equipment technology, and in particular to a manual sorting error-proofing device. Background Technology

[0002] PTC stands for Positive Temperature Coefficient. PTC products mainly refer to thermistors with positive temperature coefficient characteristics. The stability of the resistance value is one of the important indicators of product quality. In the production process of PTC products, the resistance of PTC products is tested by a resistance meter, which can promptly detect potential quality problems in the production process, helping to improve product quality and production efficiency. It can also screen and classify the produced PTC products, improving the product qualification rate. Currently, PTC products are tested by workers operating resistance meters. Due to the large number of products and the relatively fixed testing actions, workers are prone to errors due to mental and physical inertia after working for a long time. For example, after testing, products that originally belong to different categories are placed in the same material box, which can easily cause product confusion. Summary of the Invention

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the problem of product confusion caused by workers misplacing products in the material box due to operational inertia in the prior art. It provides a manual sorting error prevention device, which opens and closes the feeding port through the driver and realizes the linkage between the resistor and the driver through the controller. The controller controls the driver to open the corresponding feeding port according to the test results of the resistor, so that the worker can accurately put the product into the corresponding feeding port, eliminate the phenomenon of product misplacement, and improve the testing efficiency.

[0004] To solve the above-mentioned technical problems, this utility model provides a manual sorting error-proof device, comprising:

[0005] The workbench is provided with multiple feeding ports, each of which has a normally closed state and an open state, and all of which are set to the normally closed state.

[0006] A switching assembly includes a controller and multiple drivers, the controller being electrically connected to the multiple drivers, the multiple drivers respectively driving the multiple feed ports to switch to the normally closed state or the open state, wherein the controller controls one of the multiple drivers to open while controlling the other multiple drivers to close;

[0007] The testing component includes a resistor meter for testing the resistance value of the resistor under test. The resistor meter transmits the resistance value to the controller, and the controller controls the corresponding driver to start and switch the corresponding feed port from the normally closed state to the open state according to the resistance value.

[0008] In one embodiment of this utility model, the plurality of feeding ports are linearly distributed along the edge of the workbench.

[0009] In one embodiment of this utility model, the plurality of feeding ports are configured as a plurality of through holes located on the workbench surface, and a plurality of material boxes are respectively arranged below the plurality of through holes.

[0010] In one embodiment of this utility model, the plurality of material boxes are configured as a plurality of drawer structures.

[0011] In one embodiment of the present invention, the switch assembly includes a plurality of baffles, which are respectively connected to the output terminals of the plurality of drivers, and the drivers drive the baffles to block the through holes.

[0012] In one embodiment of this utility model, the baffle is disposed close to the upper or lower surface of the worktable, and the driver drives the baffle to slide along the upper or lower surface toward the through hole.

[0013] In one embodiment of this utility model, a plurality of indicator lights are also included. The plurality of indicator lights are respectively disposed on one side of the plurality of feeding ports, and the plurality of indicator lights are all electrically connected to the controller.

[0014] In one embodiment of this utility model, the workbench is provided with a testing station, the plurality of feeding ports are respectively located on both sides of the testing station, and the testing components are disposed at the testing station.

[0015] In one embodiment of the present invention, the test assembly includes a sensor and a metal plate disposed on top of the sensor.

[0016] In one embodiment of the present invention, the test station is provided with a limiting groove, and the test component includes a sensor and a metal plate disposed on top of the sensor, wherein both the metal plate and the sensor are located within the limiting groove.

[0017] In one embodiment of the present invention, the resistor includes a first resistor and a second resistor. The first resistor is electrically connected to a plurality of drivers located on one side of the test station via the controller, and the second resistor is electrically connected to a plurality of drivers located on the other side of the test station via the controller.

[0018] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial effects:

[0019] The manual sorting error-proof device described in this utility model has multiple feeding ports equipped with individual drivers to enable individual opening and closing of the feeding ports. The resistor and the drivers are linked through a controller. The controller can classify the resistance value and can classify multiple drivers. After the resistor sends the resistance value of the product to the controller, the controller controls the driver of the corresponding level to open according to the resistance value level, while the driver of the mismatched level is in the closed state. Therefore, after the resistor detects the product, only one feeding port switches from the normally closed state to the open state, which makes it easy for workers to accurately put the product into the corresponding feeding port and avoids product confusion.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0025] Reference Figure 1 As shown, in one embodiment of this utility model, a manual sorting error-proofing device is disclosed, which is used to test the resistance value of products and complete the product sorting. The error-proofing device includes,

[0026] The workbench 1 has five feeding ports 2, which represent five progressively increasing resistance levels. These ports are used to hold products at each of the five resistance levels. Each of the five feeding ports 2 can only be switched between a normally closed state and an open state. All five feeding ports 2 are set to the normally closed state. After the product is tested, only the feeding port 2 that matches the product's resistance level can be switched to the open state, while the other four feeding ports 2 remain in the normally closed state. Therefore, the operator can accurately put the tested product into the feeding port 2 of the corresponding resistance level, eliminating the phenomenon of mistakenly placing the product in other feeding ports 2 due to action or habitual thinking, thus improving the product testing efficiency.

[0027] A switching assembly includes a controller and five actuators 3, each preferably a cylinder. The controller is electrically connected to the five actuators 3 to individually control their opening and closing. Therefore, the five actuators 3 can respectively drive the five feeding ports 2 to switch to the normally closed state or the open state. The controller divides the five actuators 3 into five progressively larger levels. Under the control of the controller, the actuator 3 can only open the feeding port 2 corresponding to its level. For example, the actuator 3 at level 1 can only open the feeding port 2 at level 1. The controller controls only one of the five actuators 3 to open at a time, while controlling the other four actuators 3 to close, based on the resistance level of the product.

[0028] The testing component includes a resistor meter 5 for testing the resistance value of the resistor under test. The resistor meter 5 is electrically connected to the controller. The resistor meter 5 transmits the resistance value to the controller. The controller divides the resistance value into ranges. The controller controls the corresponding driver 3 to start according to the range of the resistance value, switching the corresponding feed port 2 from the normally closed state to the open state. This realizes the linkage between the resistor meter 5 and the driver 3, as well as the automatic opening and closing of the feed port 2, preventing the phenomenon of misplacement of products.

[0029] Reference Figure 1 As shown, the five feeding ports 2 are linearly distributed along the edge of the workbench 1, and the levels of the five feeding ports 2 increase sequentially, so that the operator can sit on one side of the workbench 1 to conduct product testing and quickly put the tested products into the feeding ports 2.

[0030] Reference Figure 1 As shown, the five feeding ports 2 are configured as five through holes located on the surface of the workbench 1, and five material boxes are set below the five through holes. That is, each feeding port 2 is provided with a material box for storing products, so as to collect products with different resistance values. The height of the workbench 1 is 60CM~100CM.

[0031] Reference Figure 1 As shown, in order for the material boxes to accurately receive the products falling from the feeding port 2, the five material boxes are configured as five drawer 11 structures. The drawer 11 structure can slide precisely below the feeding port 2, reducing human error.

[0032] Reference Figure 2 As shown, the switch assembly includes five baffles 4, which are respectively connected to the output terminals of the five drivers 3. The drivers 3 drive the baffles 4 to move so that the baffles 4 coincide with the through hole to block the through hole.

[0033] Reference Figure 1 As shown, further, in order to improve the safety and compactness of the foolproof device and prevent the baffle 4 from accidentally injuring the operator, the baffle 4 is set close to the lower surface of the workbench 1, and five actuators 3 are also located below the table surface of the workbench 1. The actuators 3 drive the baffle 4 to slide along the lower surface toward the through hole. In another embodiment, the baffle 4 can be provided with a thin sheet, which is close to the upper surface of the workbench 1. When the baffle 4 covers the feeding port 2, the feeding port 2 is completely concealed.

[0034] Reference Figure 1 As shown, to achieve dual error prevention, five indicator lights 12 are also included. The five indicator lights 12 are respectively set on one side of the five feeding ports 2. The five indicator lights 12 are all electrically connected to the controller. The controller also classifies the five indicator lights 12 into levels. One indicator light 12 is set on one side of a feeding port 2 that matches its level. When the controller completes the classification of the resistance value, the controller controls the indicator light 12 of the corresponding level to light up. For example, if the resistance value of the product is level 1, the controller controls the indicator light 12 of level 1 to light up, which is used to prompt the operator so that the operator can quickly find the position of the feeding port. Furthermore, the workbench 1 is provided with a mounting plate 13. The mounting plate 13 extends along the distribution direction of the five feeding ports 2. The five indicator lights 12 are connected to one side of the mounting plate 13. The mounting plate 13 can improve the reflectivity of the light and further enhance the indicativeness of the indicator lights 12.

[0035] Reference Figure 1 As shown, the workbench 1 is equipped with a testing station 14, and the testing components are set at the testing station 14. After the operator completes the product testing, he / she extends his / her arm to put the product into the designated feeding port 2 to avoid moving it back and forth.

[0036] Reference Figure 1As shown, the test assembly includes a test head 8, a pressure cylinder 6 that drives the test head 8 to descend, a sensor, and a metal plate 9 disposed on top of the sensor. The metal plate 9 is preferably a copper plate and is used to place the product to be tested. The test head 8 is used to press the product to be tested onto the metal plate 9, so that the product, the metal plate 9, and the test head 8 form a conductive state and trigger a resistance test. The sensor is set as a pressure sensor. The pressure sensor and the pressure cylinder 6 are both electrically connected to the controller. The pressure sensor detects whether the product is placed on the metal plate 9 by detecting the pressure on the metal plate 9. If the product is placed on the metal plate 9, the pressure sensor triggers the pressure cylinder 6 to press down the test head 8 and start the test.

[0037] Reference Figure 1 As shown, in order to limit the metal plate 9 and prevent the metal plate 9 from shifting, the test station 14 is provided with a limiting groove 7 that matches the metal plate 9. The metal plate 9 and the sensor are located in the limiting groove 7, and the side wall of the limiting groove 7 abuts against the side of the metal plate 9 to achieve the limiting.

[0038] Reference Figure 1 As shown, the testing station is also connected to a material box 10, which is used to store multiple products to be tested. The material box 10 is located below the metal plate 9, and the top of the material box has an opening. The operator reaches into the opening, picks up the product, and places it on the metal plate 9 above.

[0039] Reference Figure 1As shown, furthermore, in order to enable the operator to test two products simultaneously with both hands, five feeding ports 2 and five indicator lights 12 are provided on both the left and right sides of the testing station. The levels of the five feeding ports on the left side increase sequentially from 1 to 5, and the levels of the five feeding ports on the right side also increase sequentially from 1 to 5. Correspondingly, the resistance meter includes a first resistance meter 15 and a second resistance meter 5. The first resistance meter 15 is electrically connected to five drivers and five indicator lights located on the left side of the testing station 14 through the controller, that is, the first resistance meter 15 can only be linked with the five drivers and five indicator lights on the left side of the testing station 14. The second resistance meter 5 is electrically connected to five drivers and five indicator lights located on the right side of the testing station 14 through the controller. The second resistor 5 can only be linked with the five drivers and five indicator lights on the right side of the test station 14. The test station is equipped with a limiting groove 7 on the left and a limiting groove 16 on the right. The test head 8 of the first resistor 15 is located above the limiting groove 7, and the test head 17 of the second resistor 5 is located above the limiting groove 16. The operator can simultaneously grab two products to be tested with his left and right hands and put them into the limiting groove 7 and the limiting groove 16 respectively for testing. Specifically, after the product in the limiting groove 7 has completed the test, the corresponding feeding port on the left opens, and the operator puts the product into the left feeding port with his left hand. After the product in the limiting groove 16 has completed the test, the corresponding feeding port on the right opens, and the operator puts the product into the right feeding port with his right hand, which greatly improves the testing efficiency.

[0040] The working principle of the manual sorting error prevention device described in this utility model is as follows:

[0041] Each time, the operator places two products to be tested on the two metal plates 9 with their left and right hands respectively. After the sensor detects the products to be tested, the pressing cylinders 6 / 18 drive the test heads 8 / 17 to press down on the products, making the products, test heads 8, and metal plates 9 conductive and triggering the resistance test. After a 2-second delay in the conductive state, the first resistance meter 15 and the second resistance meter 5 respectively send the resistance value of the products to the controller. The controller classifies the resistance value into levels and controls one driver 3 and indicator light 12 of the same level to turn on according to the level of the resistance value. After seeing the left indicator light 12 and feeding port 2 open, the operator uses their left hand to put the product in the limiting groove 7 into the left feeding port 2. Similarly, after seeing the right indicator light 12 and feeding port 2 open, the operator uses their right hand to put the product in the limiting groove 16 into the right feeding port 2. Then, the controller controls the two indicator lights 12 to turn off, and the driver 3 drives the baffle 4 to reset and close the two feeding ports 2. Then, the two products to be tested are placed on the metal plates 9 again, and this cycle is repeated.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
