Description
Technical Field
[0001] This utility model relates to the field of testing technology, and in particular to a part error prevention installation testing device. Background Technology
[0002] In the manufacturing process, misassembly and omission of parts have long affected production efficiency and product quality. Therefore, after the parts are manufactured, assembly inspection is necessary to ensure the quality of the parts before they leave the factory. In the current technology, many manufacturing enterprises still use traditional manual visual inspection methods to inspect parts. This not only reduces equipment investment and maintenance costs, but in practical applications, manual visual inspection is not only difficult to detect the accuracy of parts, but also suffers from a high rate of missed inspections, which is not conducive to practical application. To address this, we propose a part error-proof assembly inspection device. Utility Model Content
[0003] To address the aforementioned problems, this utility model provides a part error prevention installation detection device.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] Design a part error prevention installation detection device, including a workbench, on which multiple locking detection modules of different shapes are detachably connected. Each locking detection module has a detection groove, and each detection groove has a switch pin installed on its inner wall. Each locking detection module is equipped with a detection indicator light.
[0006] In the above scheme, the workbench is equipped with connecting plates that correspond one-to-one with the locking detection modules, and the bottom of the locking detection module is fixed with a chassis.
[0007] In the above scheme, the chassis is connected to the connecting plate by fasteners.
[0008] In the above scheme, the top of the connecting plate is provided with a positioning block, the bottom of the chassis is provided with a positioning groove that fits with the positioning block, the positioning block is provided with an electromagnet, the chassis is a magnetic chassis, and the positioning block and the chassis are opposite magnetic poles on the side closest to each other.
[0009] In the above scheme, an electrode protrusion is fixed at the bottom of the chassis, and an electrode groove is opened at the top of the connecting plate to connect with the electrode protrusion.
[0010] In the above scheme, the connecting plate is movably connected to a base, and a drive shaft coaxially fixed with the connecting plate is rotatably installed in the base. A second gear is installed on the drive shaft, and a servo motor is installed in the base. A first gear that meshes with the second gear is installed on the output shaft of the servo motor.
[0011] In the above scheme, an electrical control box is provided at one end of the workbench, and the electrical control box is equipped with a running indicator light and multiple operation buttons.
[0012] The advantages and beneficial effects of this utility model are as follows: By setting a locking detection module, a detection groove, a detection indicator light, and a switch pin, the quality of the part is judged based on the assembly state after the part is assembled with the detection groove. Compared with the prior art, it can not only achieve the effect of physical error prevention through the detection groove corresponding to the shape of the part, thus realizing the purpose of error-proof detection of the part, but also, in conjunction with the switch pin, when the part is correctly pressed into the detection groove, the pin body is squeezed to trigger the micro switch, forming a circuit path and sending a position signal. Then, through signal testing, the detection indicator light is correctly lit, thus achieving a double error-proof effect and improving the reliability of detection. By setting a positioning block and a positioning groove, the chassis and connecting plate are attracted to each other by magnetic force, thus assembling the locking detection module with the worktable. Compared with the prior art, the locking detection module can be quickly disassembled and assembled to replace it with a locking detection module corresponding to the required part, which can meet the needs of detecting more different types of parts, improve flexibility, and is convenient to use.

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.
[0021] Please see Figure 1-5 The present invention provides a technical solution: a part error prevention installation detection device, including a workbench 1, on which multiple locking detection modules 3 of different shapes are detachably connected, and the locking detection modules 3 are provided with detection grooves 15 that fit the shapes of different parts, and the inner walls of the detection grooves 15 are all equipped with switch pins 16.
[0022] Specifically, the switch pin 16 adopts an elastic contact design. When the part is correctly pressed into the corresponding detection groove 15, the pin will be squeezed to trigger the micro switch, forming a circuit path and sending a position signal. Only when the switch pin 16 is fully pressed down will a valid signal be issued; otherwise, it is judged as an erroneous operation. The mechanical trigger can complete the signal transmission within 50ms, which is much faster than the vision inspection system. In addition, the high-quality switch pin 16 can withstand more than 1 million presses, and its gold-plated contacts can also prevent oxidation failure.
[0023] Furthermore, the bottom of the chassis 10 is fixed with an electrode protrusion 13, and the top of the connecting plate 4 is provided with an electrode groove 14 that connects to the electrode protrusion 13. The connecting plate 4 is electrically connected to the power supply. When the electrode protrusion 13 is inserted into the electrode groove 14, the chassis 10 is connected to the power supply circuit.
[0024] Furthermore, the workbench 1 is equipped with connecting plates 4 that correspond one-to-one with the locking detection module 3. The workbench 1 has mounting grooves, the connecting plates 4 are placed in the mounting grooves, and the bottom of the locking detection module 3 is fixed with a base plate 10.
[0025] Furthermore, the chassis 10 is connected to the connecting plate 4 by fasteners, and the bottom of the chassis 10 has connecting holes for installing fasteners.
[0026] The locking detection module 3 is equipped with a detection indicator light 19. At least two detection indicator lights 19 are provided. One detection indicator light 19 can be used to check whether the locking detection module 3 and the detection chassis 10 are connected to the power supply circuit, and the other is used to provide feedback on the detection results of the parts.
[0027] Specifically, by setting up a locking detection module 3, a detection groove 15, a detection indicator light 19, and a switch pin 16, the quality of the part is judged based on the assembly state by assembling the part with the detection groove 15. Compared with the existing technology, not only can the detection groove 15, which corresponds to the shape of the part, achieve the effect of physical error prevention and thus realize the purpose of error-proof detection of the part, but also, in conjunction with the switch pin 16, when the part is correctly pressed into the detection groove 15, the pin body is squeezed to trigger a micro switch, forming a circuit path and sending a position signal. Then, through signal testing, the detection indicator light 19 is correctly lit, thereby achieving a double error-proof effect and improving the reliability of detection.
[0028] Furthermore, the top of the connecting plate 4 is fixedly provided with a positioning block 11, and the bottom of the chassis 10 is provided with a positioning groove 12 that fits with the positioning block 11. The positioning block 11 is an electromagnet, the chassis 10 is a magnetic chassis, and the positioning block 11 and the chassis 10 are opposite magnetic poles on the side close to each other. The surface of the chassis 10 and the inner wall of the positioning groove 12 are coated with a magnetic coating that is opposite to the magnetism of the positioning block 11.
[0029] Specifically, by setting the positioning block 11 and the positioning groove 12, the chassis 10 and the connecting plate 4 are attracted to each other by magnetic force, thereby assembling the locking detection module 3 with the worktable 1. Compared with the prior art, the locking detection module 3 can be quickly disassembled and assembled so as to replace it with the locking detection module 3 corresponding to the required parts. This can meet the needs of testing more different types of parts, improve flexibility, and make it easy to use.
[0030] Furthermore, the connecting plate 4 is movably connected to a base 5. A drive shaft 8, coaxially fixed with the connecting plate 4, is rotatably installed inside the base 5. A second gear 9 is installed on the drive shaft 8. A servo motor 6 is installed inside the base 5. A first gear 7, which meshes with the second gear 9, is installed on the output shaft of the servo motor 6. The servo motor 6 provides power to make the first gear 7 rotate, which in turn drives the second gear 9 and the drive shaft 8 to rotate, thereby causing the connecting plate 4 to rotate. This allows the angle between the locking detection module 3 and the part to be adjusted, which makes it easier for the staff to observe the part and also avoids interference between adjacent locking detection modules 3.
[0031] Furthermore, one end of the workbench 1 is equipped with an electrical control box 2, which contains a power supply module and a PLC. The electrical control box 2 is equipped with a running indicator light 17 and multiple operation buttons 18. The electrical control box 2 is also equipped with some instruments and power indicator lights for detecting environmental indices.
[0032] Working principle:
[0033] After the electrical control box 2 is powered on, the power indicator light will illuminate. After the PLC completes its self-test cycle, the running indicator light 17 will illuminate, and all detection and locking modules 3 will remain constantly red. The manual and automatic modes can be switched using the operation button 18. When the operator places a part into the corresponding locking detection module 3 and presses it into place to trigger the switch pin 16, the locking detection module 3 will lock the product. At this time, the red light of one of the detection indicator lights 19 will turn green. If different parts are placed in the wrong position, the detection groove 15 and the switch pin 16 can prevent errors. If the red light cannot turn green, the signal test will fail. After all the locking detection modules 3 turn green, the locking detection modules 3 will unlock, and the test will be passed. If any problems are found during operation and the product needs to be removed, the PLC program can be reset using the operation button 18 to unlock the locking detection module 3. In automatic mode, the MES can send a signal to the PLC to unlock the locking detection module 3.
[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
