Description

Technical Field

[0001] This utility model relates to the field of testing equipment, and in particular to a resistance testing mechanism and resistance testing equipment. Background Technology

[0002] When changing the type of automated equipment in an enterprise, the IR (insulation resistance) value of the product needs to be tested after spot welding and adhesive application. Currently, some resistance testing institutions manufacture probe holders of corresponding sizes and with probes fixed according to the relative positions of the nickel plates on both sides of the product. This means that the probe holders need to be disassembled and replaced with probe holders of the corresponding model every time the product model is changed, which is inefficient and affects the product model changeover.

[0003] Therefore, there is an urgent need for a resistance testing organization that can perform resistance testing on products of various models. Utility Model Content

[0004] The purpose of this invention is to provide a resistance testing mechanism that can perform resistance testing on various types of products.

[0005] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0006] A resistance testing mechanism, comprising:

[0007] A probe assembly for contacting the object to be detected;

[0008] The bracket includes an adjustment main component and an adjustment sub-component, the adjustment sub-component being detachably connected to the adjustment main component, and the installation position of the adjustment sub-component being adjustable in the horizontal plane, the adjustment sub-component being connected to the probe assembly.

[0009] As an optional solution for the resistance detection mechanism, the main adjustment component is provided with a first elongated horizontal hole, and the resistance detection mechanism also includes a first fastener, which passes through the first elongated hole to connect the adjustment sub-component to the main adjustment component.

[0010] As an optional solution for the resistance detection mechanism, the adjustment sub-part is provided with a second elongated hole, the first fastener slides through the first elongated hole and the second elongated hole, and can be detachably connected to the adjustment sub-part and the adjustment main part so that the first elongated hole and the second elongated hole are set at an angle.

[0011] As an optional solution for the resistance detection mechanism, the number of adjustment components is set to at least two, and each adjustment component is connected to the probe assembly.

[0012] As an optional solution for the resistance detection mechanism, the main adjustment component includes a connector and two adjustment components. The two adjustment components are formed by extending from opposite ends of the same side edge of the connector, and the probe assembly is located between the two adjustment components.

[0013] As an optional solution for this resistance testing mechanism, the resistance testing mechanism also includes:

[0014] Loading plate;

[0015] A drive assembly is mounted on the loading plate and connected to the bracket for driving the bracket to move up and down.

[0016] As an optional solution for the resistance detection mechanism, the main adjustment component is detachably connected to the drive assembly, and the installation position of the main adjustment component in the horizontal direction is adjustable.

[0017] As an optional solution for the resistance detection mechanism, the main adjustment component also has a third elongated horizontal hole.

[0018] As an optional solution for the resistance detection mechanism, the loading plate is provided with a fourth elongated hole, and the resistance detection mechanism also includes a third fastener, which passes through the fourth elongated hole and is connected to a designated installation position.

[0019] A resistance detection device includes a display and a resistance detection mechanism. The display is electrically connected to the resistance detection device and is used to detect the resistance of the object to be tested.

[0020] The beneficial effects of this utility model are as follows:

[0021] This utility model proposes a resistance detection mechanism in which the adjustment sub-component and the adjustment main component are detachably connected, and the installation position of the adjustment sub-component is adjustable in the horizontal plane. The adjustment sub-component is connected to the probe assembly, so that the position of the probe can be adjusted according to the specifications of the test piece. When the specifications of the test piece are changed, it is not necessary to replace the entire resistance detection assembly.

[0022] The first and second elongated holes work together to allow the adjustment sub-component to not only translate but also rotate, making the position adjustment of the probe assembly more flexible. This allows the probe assembly to be adjusted within the extension limits of the main adjustment component and the adjustment sub-component, thereby adapting to the specifications of different test pieces.

[0030] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effects achieved clearer, the technical solution of this invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining this invention and are not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts related to this invention are shown in the accompanying drawings, not all of them.

[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] like Figure 1-2 As shown, this embodiment provides a resistance detection mechanism. The resistance detection mechanism includes a probe assembly 1 and a support 2. The probe assembly 1 is used to contact the object to be tested. The support 2 includes an adjustment main component 21 and an adjustment sub-component 22. The adjustment sub-component 22 is detachably connected to the adjustment main component 21, and the installation position of the adjustment sub-component 22 is adjustable in the horizontal plane. The adjustment sub-component 22 is connected to the probe assembly 1. Because the installation position of the adjustment sub-component 22 is adjustable in the horizontal plane, the position of the probe assembly 1 can also be adjusted in the horizontal plane. This allows the position of the probe assembly 1 to be adaptively adjusted according to the specifications of the object to be tested. Furthermore, since the adjustment sub-component 22 is detachably connected to the adjustment main component 21, it is not necessary to replace the entire resistance detection mechanism when the specifications of the object to be tested change; only the relative position of the adjustment sub-component 22 and the adjustment main component 21 needs to be adjusted.

[0036] Optionally, such as Figure 1-2 As shown, in this embodiment, the main adjustment component 21 is provided with a horizontally extending first elongated hole 2121. The resistance detection mechanism also includes a first fastener. The first fastener passes through the first elongated hole 2121 to connect the adjustment sub-component 22 and the main adjustment component 21 together, so that the position of the adjustment sub-component 22 can move along the extension direction of the first elongated hole 2121, that is, the position of the adjustment sub-component 22 can move linearly in the horizontal direction. Since the probe assembly 1 is connected to the adjustment sub-component 22, the probe assembly 1 can make horizontal adjustments according to the specifications of the component to be tested.

[0037] Combination Figure 1-2 As shown, for ease of explanation, the extension direction of the first elongated hole 2121 is the first direction. The installation position of the adjustment sub-part 22 on the adjustment main part 21 can be adjusted along the first direction to adjust the position of the probe assembly 1 along the first direction.

[0038] In other embodiments, the first elongated hole 2121 can be disposed on the adjustment sub-part 22, and the first fastener passes through the first elongated hole 2121 to connect the adjustment sub-part 22 and the adjustment main part 21 together, so that the position of the adjustment sub-part 22 can also move along the extension direction of the first elongated hole 2121, so that the probe assembly 1 can be adjusted in position within the extension limit range of the first elongated hole 2121 to adapt to the specifications of different test pieces.

[0039] In other embodiments, either the main adjusting member 21 or the secondary adjusting member 22 may be provided with a plurality of first mounting holes arranged in a straight line along the first direction. By replacing the first elongated hole 2121 with a plurality of first mounting holes, the first fastener can selectively cooperate with any of the first mounting holes and connect the secondary adjusting member 22 and the main adjusting member 21 together, thereby realizing the change of the position of the secondary adjusting member 22 along the first direction.

[0040] Optionally, the first fastener can be a pin, screw, or bolt and nut structure.

[0041] Optionally, such as Figure 1-2 As shown, in this embodiment, the adjusting sub-component 22 is provided with a second elongated hole 221. The first fastener passes through the first elongated hole 2121 and the second elongated hole 221, and then the adjusting sub-component 22 and the adjusting main component 21 are fixed. After fixing, the first elongated hole 2121 and the second elongated hole 221 are set at an angle. When adjusting the position of the probe assembly 1, the first fastener can slide in the first elongated hole 2121 along its extension direction, and the first fastener can slide in the second elongated hole 221 along its extension direction, thereby realizing the adjustment of the position of the probe assembly 1 in the horizontal plane.

[0042] Optionally, when fixing the adjusting sub-part 22 and the adjusting main part 21, the included angle between the first elongated hole 2121 and the second elongated hole 221 can be an acute angle or a right angle. For example, as shown... Figure 1 and Figure 2 As shown, the angle between the first elongated hole 2121 and the second elongated hole 221 is a right angle, that is, the first elongated hole 2121 and the second elongated hole 221 are perpendicular, so that the position of the probe assembly 1 can move in the plane.

[0043] For ease of explanation, the following text will use the extension direction of the second elongated hole 211 perpendicular to the first elongated hole 2121 as the second direction.

[0044] In other embodiments, the elongated hole (first elongated hole 2121 or second elongated hole 221) provided on at least one of the main adjustment member 21 and the auxiliary adjustment member 22 can be replaced by a plurality of second mounting holes arranged in a straight line.

[0045] In other embodiments, one of the main adjustment component 21 and the auxiliary adjustment component 22 is provided with a plurality of third mounting holes arranged in a matrix, with the rows of the matrix along a first direction and the columns of the matrix along a second direction. After the first fastener passes through one of the main adjustment component 21 and the auxiliary adjustment component 22, it engages with any of the third mounting holes of the other, which can also move the position of the probe assembly 1 in the plane to adapt to the functions of different test pieces.

[0046] Specifically, such as Figure 1-2 As shown, in this embodiment, the main adjustment component 21 and the auxiliary adjustment component 22 are detachably connected. Through the cooperation of the second elongated hole 221 and the first elongated hole 2121, the auxiliary adjustment component 22 can rotate on the main adjustment component 21 with the first fastener as the pivot. This allows the probe assembly 1 to rotate with the auxiliary adjustment component 22, thereby making the position adjustment function of the bracket 2 more diverse and adaptable to different specifications of test pieces.

[0047] Since the resistance of the device under test is being measured, it needs to be placed in a closed loop. At least two probe assemblies 1 are required. Because different specifications of devices need to be tested, it is best that each of the at least two probe assemblies 1 is connected to an adjustment sub-assembly 22. Therefore, at least two adjustment sub-assemblies 22 are required, each connected to a probe assembly 1. This arrangement allows the device under test to be connected to a closed loop via at least two probes, enabling normal resistance measurement. The number of adjustment sub-assemblies 22 should not be excessive. If ten adjustment sub-assemblies 22 are used, it will be redundant. The main adjustment assembly 21 does not need too many adjustment sub-assemblies 22 to change the position of the probe assembly 1, and too many adjustment sub-assemblies 22 on the main adjustment assembly 21 will occupy too much area, preventing other components from being connected to it. For example, two, three, or four adjustment sub-assemblies 22 can be used. Figure 1-2 As shown, in this embodiment, the number of adjustment sub-components 22 is set to two, so that the resistance detection mechanism can use a simpler and more concise structure to detect the test piece, and also effectively avoids functional redundancy.

[0048] Optionally, in this embodiment, as Figure 1-2 As shown, the main adjustment component 21 includes a connector 211 and two adjustment components 212. The two adjustment components 212 are formed by extending from opposite ends of the same side edge of the connector 211. The probe is located between the two adjustment components 212. The above arrangement avoids the situation of no adjustment component 212 extending outward during the resistance detection process, thereby avoiding interference of the main adjustment component 21 with the detection process.

[0049] In other embodiments, the connector 211 and the adjuster 212 can be separate components, and the connector 211 and the adjuster 212 can be detachably connected. The connector 211 is also provided with a fourth mounting hole. The resistance detection mechanism also includes a fourth fastener, which passes through the fourth mounting hole to connect the connector 211 and the adjuster 212 together, so that when the main adjustment component 21 is under maintenance, the damaged parts can be replaced in a targeted manner.

[0050] Alternatively, the fourth fastener may be a pin, screw, or bolt and nut structure.

[0051] Optionally, in this embodiment, the fourth mounting hole can be an elongated hole, and the extension direction of the fourth mounting hole is the second direction. The mounting position of the adjusting member 212 on the connecting member 211 can be adjusted along the second direction to adjust the position of the probe assembly 1 along the second direction.

[0052] In other embodiments, a fourth mounting hole may be provided on the adjustment member 212, and a fourth fastener passes through the fourth mounting hole to connect the connector 211 and the adjustment member 212 together, so that the position of the adjustment member 212 can also move along the extension direction of the fourth mounting hole, so that the probe assembly 1 can be adjusted in position within the extension limit range of the fourth mounting hole to adapt to different test pieces.

[0053] In other embodiments, either the connector 211 or the adjuster 212 may be provided with a plurality of fifth mounting holes arranged in a straight line along the second direction. By replacing the fourth mounting hole with a plurality of fifth mounting holes, the fourth fastener may selectively cooperate with any of the fifth mounting holes to connect the connector 211 and the adjuster 212 together, thereby realizing the change of the position of the adjuster 212 along the second direction.

[0054] Specifically, such as Figure 1-2 As shown in this example, the resistance detection mechanism also includes a loading plate 4 and a drive component 3. The drive component 3 is mounted on the loading plate 4 and connected to the bracket 2. It is used to drive the bracket 2 to move up and down. Since the bracket 2 is connected to the probe component 1, the probe component 1 can move up and down through the drive mechanism without manually adjusting the up and down position. This not only reduces the waste of human resources but also improves the detection efficiency.

[0055] It should be noted that the driving component 3 is an existing structure. Setting the driving component 3 in the resistance detection mechanism is a conventional setting in the field. In this embodiment, any driving component 3 in the prior art can be used, and any connection method in the prior art can be used to connect it to the bracket 2, as long as the bracket 2 can be moved up and down. No further details will be provided.

[0056] Specifically, such as Figure 1-2As shown, in this embodiment, the main component 21 and the drive assembly 3 are detachably connected. The installation position of the main component 21 in the horizontal direction is adjustable, so that the resistance detection mechanism can better adapt to the changes in the position and specifications of the component to be tested. At the same time, when the resistance detection mechanism is repaired, it can be replaced according to the damaged parts instead of replacing the entire mechanism.

[0057] Optionally, such as Figure 1-2 As shown, in this embodiment, the main adjustment component 21 is also provided with a horizontally extending third elongated hole 213. The resistance detection mechanism also includes a second fastener, which passes through the third elongated hole 213 and is connected to the drive component 3, so that the position of the bracket 2 can be moved in the horizontal direction. Since the probe component 1 is connected to the bracket 2, the probe component 1 can be adjusted in the horizontal direction according to the specifications of the part to be tested.

[0058] Alternatively, the second fastener can be a pin, screw, or bolt and nut structure.

[0059] In other embodiments, the main adjusting component 21 may be provided with a plurality of sixth mounting holes that extend horizontally and are arranged in a straight line. By replacing the third elongated hole 213 with a plurality of sixth mounting holes, the second fastener can selectively cooperate with any of the sixth mounting holes and connect the drive component 3 and the main adjusting component 21 together, thereby realizing the change of the position of the bracket 2 in the horizontal direction, so that the position of the probe component 1 connected to the bracket 2 in the horizontal direction can also be changed.

[0060] In other implementations, the main component 21 can also be provided with multiple seventh mounting holes arranged in a matrix, with the rows of the matrix along the first direction and the columns along the second direction. After the fastener passes through the drive assembly 3, it cooperates with any of the seventh mounting holes, allowing the position of the probe assembly 1 to move in the plane to accommodate the functions of different test pieces. Optionally, in this embodiment, as... Figure 1-2 As shown, the extension direction of the third elongated hole 213 is perpendicular to the extension direction of the first elongated hole 2121 in the plane of the adjusting main component 21, so that the probe assembly 1 can be adjusted in position within the extension limits of the third elongated hole 213 and the first elongated hole 2121 to adapt to the test piece in different positions. In other embodiments, the positional relationship between the extension direction of the third elongated hole 213 and the extension direction of the first elongated hole 2121 can be an acute angle or any other angle, as long as it allows the probe assembly 1 to adapt to the test piece in different positions, which will not be elaborated further.

[0061] Optionally, such as Figure 1-2As shown, in this embodiment, the loading plate 4 also has a fourth elongated hole 41. The resistance detection mechanism also includes a third fastener, which passes through the fourth elongated hole 41 and connects to a designated mounting position. This allows the loading plate 4 to be moved along the extension direction of the fourth elongated hole 41 to adapt to changes in the position and specifications of the component under test, enabling flexible adjustment of the position of the resistance detection mechanism. In other embodiments, the loading plate 4 may have multiple eighth mounting holes arranged in a straight line. The third fastener passes through one of the eighth mounting holes to connect the loading plate 4 to a designated mounting position, thereby allowing the loading plate 4 to change along the arrangement direction of the eighth mounting holes. The key is to ensure that the position of the loading plate 4 can be flexibly changed.

[0062] Alternatively, the third fastener can be a pin, screw, or bolt and nut structure.

[0063] Optionally, in this embodiment, as Figure 1-2 As shown, the extension direction of the fourth elongated hole 41 is parallel to the extension direction of the first elongated hole 2121, allowing the probe assembly 1 to be positioned within the extension limits of the fourth elongated hole 41 and the first elongated hole 2121 to accommodate the test piece at different positions. In other embodiments, the positional relationship between the extension directions of the fourth elongated hole 41 and the first elongated hole 2121 can be an acute angle or any other angle, as long as it allows the probe assembly 1 to adapt to the test piece at different positions; further details are omitted.

[0064] Optionally, in this embodiment, as Figure 1 As shown, there are two fourth elongated holes 41, and two third elongated holes 213 are respectively set at both ends of the bottom of the loading plate 4 along the vertical direction. This allows the fourth elongated holes 41 to not only fix the loading plate 4, but also to distribute the force on the loading plate 4 evenly due to the setting of the fourth elongated holes 41 at both ends of the bottom of the loading plate 4 along the vertical direction. This avoids the loading plate 4 being damaged by uneven force when it is fixed in a designated position and connected.

[0065] This embodiment also provides a resistance testing device, which includes a display and a resistance testing mechanism. The display and the resistance testing mechanism are electrically connected. A probe contacts the object to be tested and forms a closed circuit with the display and other mechanisms, allowing the resistance value of the object to be tested to be displayed on the screen, thus enabling a more intuitive detection of the object's resistance. Furthermore, the resistance testing mechanism facilitates the resistance testing of objects of various specifications.

[0066] It should be noted that the display is an existing structure, and setting up a display in a resistance detection device is a conventional setup in the field. In this embodiment, any type of display in the prior art can be used, and any connection method in the prior art can be used to connect it to the resistance detection mechanism, as long as the resistance value of the object to be tested can be displayed on the screen. No further details will be provided.

[0067] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
