Description

TECHNICAL FIELD

[0001] The present application relates to a micro switch OP value detection device. BACKGROUND

[0002] Before the micro switch leaves the factory, the contact point interval of the micro switch will be detected, that is, the OP value (that is, the action position of the micro switch) will be detected to determine whether the micro switch meets the use requirements. At present, the detection of the OP (Operating Position, that is, the action position) value of the micro switch is usually carried out by using a measuring tool in cooperation with an operator, that is, the operator holds the measuring tool with one hand and holds the micro switch with the other hand, and then reads the data on the measuring tool to achieve the purpose of detection. Therefore, such operation is very cumbersome, especially for the entire production line, and such detection of the OP value is relatively low in efficiency.

[0003] At present, there is a micro switch OP value detection device on the market, which comprises a base, a detection block slidingly arranged on the base, and a detection table arranged on the base. One side of the detection block has a stepped profile, and the detection table is used to fix the micro switch and make the pins of the micro switch contact the prompt module. When the detection block is pushed to slide along the base, the driving rod of the micro switch can be gradually pressed down, and the trigger state of the micro switch can be prompted through the prompt module, so as to determine whether the OP value of the micro switch meets the requirements. However, since the OP value of the micro switch actually has upper limit value and lower limit value, the existing detection device cannot quickly and accurately distinguish whether the micro switch has upper limit value fault or lower limit value fault. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides a detection device which can quickly and accurately distinguish whether the micro switch has upper limit value fault or lower limit value fault.

[0006] Further, each prompt module comprises one or two light emitting units.

[0007] Further, the light emitting unit of each prompt module is one; whether the corresponding detection is qualified or not is distinguished based on whether the light emitting unit emits light or not.

[0008] Further, the light emitting unit of each prompt module is two and is different in color; the two light emitting units of each prompt module respectively represent that the corresponding detection is qualified or unqualified.

[0009] Further, each prompt module further comprises a sound emitting unit.

[0012] Further, the two auxiliary switches are arranged in vertical stacking; the other side of the detection block is provided with two abutting portions corresponding to the two auxiliary switches and arranged at different positions in the vertical direction.

[0013] Furthermore, when the detection block slides to the upper limit detection position, only one set of abutting parts and auxiliary switches cooperate to press and trigger; when the detection block slides to the lower limit detection position, both sets of abutting parts and auxiliary switches press and trigger simultaneously.

[0014] Furthermore, the auxiliary switch includes a rocker that cooperates with the detection block to be triggered by pressure. One end of the rocker is connected to the auxiliary switch in a swinging manner, and the other end of the rocker is a free end. The other end of the rocker has an arc-shaped driving part.

When the driving detection block slides relative to the base, when the upper limit detection segment and the lower limit detection segment of the detection block are respectively in the position corresponding to the pressing engagement of the driving rod of the microswitch, the sensing module can identify and sense them respectively, and coordinate with two prompting modules to provide prompts when the upper limit detection and lower limit detection are qualified. This allows for quick and accurate judgment of whether the OP value of the microswitch is qualified, and also allows for differentiation between upper limit and lower limit failures of the microswitch OP.

[0021] Examples of implementations of the micro switch OP value detection device of the present invention Figures 1-5 As shown, it includes a base 1, a detection block 2 disposed on the base 1, a detection platform 3, and a prompting module. The detection block 2 and the base 1 are in a sliding fit. The detection platform 3 is used to cooperate with the micro switch 0 to be tested for installation and positioning. The detection platform 3 is provided with a contact piece that cooperates with the pin of the micro switch 0 to be tested for conductive contact. The contact piece and the prompting module are electrically connected.

[0022] like Figure 1As shown, one side of the detection block 2 includes a contact mating surface with a stepped profile. The contact mating surface is used to engage with the drive rod of the micro switch 0 to be tested. Based on the sliding of the detection block 2, the drive rod of the micro switch 0 to be tested can be pressed down to different stroke positions. The contact mating surface includes an upper limit detection segment corresponding to the upper limit detection and a lower limit detection segment corresponding to the lower limit detection, which are arranged along the sliding distribution of the detection block 2. The upper limit detection segment includes a first slope 211 and a first flat surface 212 connected in sequence. The lower limit detection segment includes a second slope 213 and a second flat surface 214 connected in sequence. The first flat surface 212 is connected to the second slope 213. When the detection block 2 slides relative to the base 1 in a single direction, the first slope 211 can drive the drive rod of the micro switch 0 to be detected to be pressed down, and the first flat surface 212 can keep the drive rod of the micro switch 0 to be detected pressed down at the lowest position corresponding to the first slope 211. Similarly, when the detection block 2 continues to slide in the same direction, the second slope 213 can also drive the drive rod of the micro switch 0 to be detected to be pressed down, and the second flat surface 214 can keep the drive rod of the micro switch 0 to be detected pressed down at the lowest position corresponding to the second slope 213. The pressing stroke of the drive rod of the micro switch to be detected corresponding to the first flat surface 212 and the second flat surface 214 are the upper limit detection position and the lower limit detection position of the micro switch to be detected, respectively.

[0023] In this embodiment, a slide rail 11 is provided on the base 1, and a sliding groove is provided on the detection block 2 to guide the sliding of the slide rail 11. The detection block 2 and the slide rail 11 form a detachable sliding connection, which allows the detection block 2 to be disassembled and replaced to provide a pressing stroke for detecting the upper and lower OP limits of different micro switches, thus adapting to the detection of the upper and lower OP limits of different models of micro switches. In other embodiments, to facilitate the disassembly and installation of the detection block 2 and the slide rail 11, a slider is also slidably provided on the slide rail 11, and the detection block 2 and the slider are detachably fixed by, for example, screws. Similarly, the detection platform 3 and the base 1 form a detachable connection by screws. By replacing the detection platform 3, it can be adapted to the installation positioning and pin contact conductivity of different models of micro switches, thereby enabling the detection of the upper and lower OP limits of different models of micro switches.

[0024] The prompting module includes a sensing module for identifying whether the detection block 2 slides to the upper limit detection position or the lower limit detection position, and two prompting modules that are linked to the sensing module when the detection block 2 slides to the upper limit detection position and the lower limit detection position, respectively. The two prompting modules can provide prompts when the upper limit detection and lower limit detection are qualified. The detection of the upper limit and lower limit actually refers to the detection of whether the micro switch under test is pressed and triggered when the drive rod of the micro switch under test is in the pressing position corresponding to the first flat surface 212 and the second flat surface 214, respectively. Therefore, it is only necessary to detect the connection between the pins of the micro switch under test to determine whether the micro switch under test has been triggered. Conventional OP value detection devices also use this approach. In this invention, the sensing module can be used to identify whether the current state is upper limit detection or lower limit detection. The setting of the two prompting modules can be used to distinguish the qualified state of the upper limit detection and lower limit detection, thereby facilitating the testing personnel to quickly and accurately identify and judge the upper limit fault and lower limit fault of the micro switch OP. In the existing technology, although there are microswitch OP value detection devices that can detect multiple OP values ​​of microswitches at the same time, they usually use the same prompting module, which cannot quickly and accurately distinguish the cause of microswitch failure, resulting in low efficiency and easy errors.

[0025] In this embodiment, each indicator module includes two light-emitting units, which are LEDs capable of producing red and green light respectively. Green indicates pass / fail, and red indicates fail / fail. In other embodiments, a single light-emitting unit can be used, with the pass / fail status determined by whether this unit emits light. This provides intuitive feedback to inspectors and improves product testing efficiency.

[0026] To further improve the feedback effect for testing personnel, each prompt module also includes a sound unit, which uses a buzzer to issue a reminder when the corresponding test item fails.

[0027] The two prompting modules are respectively set on both sides of the base 1 relative to the detection table 3. The two prompting modules are arranged in a left-right distribution, which can improve the recognition speed of the detection personnel and reduce the error rate.

[0028] like Figures 2-4As shown, the sensing module includes two auxiliary switches 4 mounted on the base 1. The auxiliary switches 4 are microswitches, and they are linked to two corresponding prompting modules. The auxiliary switches 4 are positioned on the other side of the detection block 2, and are triggered by pressing on the other side of the detection block 2 in conjunction with the auxiliary switches 4. By positioning the auxiliary switches 4 along the sliding path of the detection block 2, they can be activated by pressing when the detection block 2 slides to the corresponding position. This enables the detection and identification of the sliding position of the detection block 2, and further allows for the identification of whether the current position is at the upper or lower limit of the detection range.

[0029] The sensing module using the above implementation method has a simple structure, low cost, and high accuracy.

[0030] Two auxiliary switches 4 are stacked together in the vertical direction. On the other side of the detection block 2, two abutting parts (22, 23) are provided at different positions in the vertical direction to be triggered by pressing against the two auxiliary switches 4. The two abutting parts are located at different positions along the sliding direction of the detection block 2, so that the detection block 2 can trigger the two auxiliary switches 4 in sequence when sliding.

[0031] When the detection block 2 slides to the upper limit detection position, only one set of abutting parts and auxiliary switch 4 cooperate to press and trigger. When the detection block 2 slides to the lower limit detection position, both sets of abutting parts and auxiliary switch 4 press and trigger simultaneously.

[0032] The circuit schematic of this invention is as follows: Figure 5 As shown, the sensing module, the prompting module, and the micro switch to be tested are connected to the same detection circuit. The detection circuit is also equipped with a power supply (battery) to provide power for the operation of the prompting module. The power supply is located on the base 1. These electrically connected components are connected by conductors arranged on the base 1.

[0033] When the detection block 2 slides to the upper limit detection position, auxiliary switch K1 is turned on, and auxiliary switch K2 remains off. If the micro switch under test is not triggered at this pressing stroke position, green light 1 will be active, while red light 1 and buzzer 1 will not be active, indicating that the upper limit OP value of the micro switch under test is qualified. Conversely, if the micro switch under test is triggered, red light 1 and buzzer 1 will be active, while green light 1 will not be active, indicating that the upper limit OP value of the micro switch under test is unqualified.

[0034] When the detection block 2 slides to the lower limit detection position, auxiliary switches K1 and K2 are simultaneously turned on. If the micro switch under test is not triggered at this pressing stroke position, red light 2 and buzzer 2 will operate, while green light 2 will not operate, indicating that the lower limit OP value of the micro switch under test is unqualified. Conversely, if the micro switch under test is triggered, green light 2 will operate, while red light 2 and buzzer 2 will not operate, indicating that the lower limit OP value of the micro switch under test is qualified.

[0035] The auxiliary switch 4 includes a rocker plate 41 that cooperates with the detection block 2 to be triggered by pressure. One end of the rocker plate 41 is connected to the housing of the auxiliary switch 4 by swinging, and the other end of the rocker plate 41 is a free end. The other end of the rocker plate 41 has an arc-shaped driving part 411. The rocker plate 41 and the driving part 411 can improve the triggering effect of the auxiliary switch 4, reduce wear, and also facilitate the reverse movement of the detection block 2.

[0036] The above embodiments are merely one preferred embodiment of the present invention. Ordinary variations and substitutions made by those skilled in the art within the scope of the technical solution of the present invention are all included within the protection scope of the present invention.
