Description

Technical Field

[0001] The utility model relates to the technical field of switch detection, in particular to a momentary break detection device and a switch detection equipment. Background Art

[0002] As a basic electronic component, switches are widely used in various electrical control circuits. Their working principle is to use the connection and disconnection of switch contacts to control the on-off function of related circuits. Therefore, the contact stability of switch contacts is a key parameter for considering the quality of switch products. In order to ensure the reliable quality of switch products, product performance testing during the manufacturing process is very important.

[0003] During the switch production process, the micro switch needs to be tested for on-off, withstand voltage, impedance and instantaneous break to ensure the production pass rate of the micro switch. Among them, the instantaneous break test is to detect whether the switch can effectively disconnect or connect the circuit when it is closed or opened. In other words, the instantaneous break test can detect the contact stability of the switch contacts.

[0004] In actual use, when pressing a button, the user may press the button from different angles, that is, there is an angle between the direction of the force applied by the user to the button and the direction of the button's expansion and contraction. In this process, the button may not be pressed into place, thus affecting the normal operation of the device.

[0046] Before any embodiments of the application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the above drawings.

[0047] In this application, the terms "comprises", "includes", "has" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element.

[0048] In the present application, the term "and / or" is a description of the association relationship of associated objects, indicating that three relationships may exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump can represent: the existence of a centrifugal vortex magnetic pump alone, the existence of a centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump at the same time, and the existence of a centrifugal vortex magnetic pump alone. In addition, the character " / " in the present application generally indicates that the objects associated before and after are in an "and / or" relationship.

[0049] In the present application, the terms "connect", "combine", "couple", and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, direct connection refers to two parts or components being connected together without the need for an intermediate piece, and indirect connection refers to two parts or components being connected to at least one intermediate piece respectively, and the two parts or components being connected via the intermediate piece. In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings, and may include electrical connections or couplings.

[0050] In the present application, it will be understood by those of ordinary skill in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerance caused by manufacturing, assembly, and use associated with a specific value, etc. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0051] In this application, it will be understood by those skilled in the art that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0052] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application.

It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, the bottom can include directly below, lower left, lower right, lower front, and lower back, etc.

[0053] See also Figures 1 to 6In this embodiment, a switch detection device for performing instantaneous break detection on a switch 100 is proposed, which includes a transfer device 200 and an instantaneous break detection device. The detection fixture 1 is arranged on the transfer end of the transfer device 200, and the transfer device 200 is configured to transfer the detection fixture 1 to between the detection mechanism 2 of the instantaneous break detection device and the pressing component 3 of the instantaneous break detection device. It can be understood that when the switch 100 is tested, the switch 100 is transferred to different testing stations, such as the continuity, withstand voltage, impedance and instantaneous break testing stations, by the transfer device 200. Compared with manually controlling the switch 100 to different stations for different tests, the detection efficiency can be greatly improved, and the labor cost can also be reduced.

[0054] Preferably, the transport device is a disc, and the disc can rotate around its own axis, and the on-off, withstand voltage, impedance and instantaneous break test stations are evenly distributed around the disc. Under the action of the disc, the switch 100 to be tested can be transported between different test stations. Such a setting can not only reduce the floor space occupied by the entire switch test equipment, but also can test multiple switches 100 to be tested, so as to improve the overall test efficiency.

[0055] Furthermore, the present embodiment also proposes a momentary break detection device, which includes a detection fixture 1, a detection mechanism 2 and a pressing component 3. The detection fixture 1 is arranged on a disc and is used to carry the switch 100 to be detected; the probe 23 of the detection mechanism 2 can be connected to the terminal 110 of the switch 100 so that the switch 100 is connected to the detection circuit, and the switch 100 can close or close the detection circuit, and the detection mechanism 2 is configured to perform momentary break detection on the switch 100; the pressing component 3 is arranged opposite to the switch 100, and the pressing component 3 can approach the switch 100 to press the button 120 of the switch 100, so that the button 120 moves along the travel path to close the switch 100; because the pressing component 3 is arranged opposite to the button 120, it cannot simulate the situation where the user presses the button 120 from the side, resulting in the inability to detect the switch 100 in all directions when performing momentary break detection. In this embodiment, after the pressing component 3 contacts the button 120 , an abutting force is applied to the pressing component 3 , so that the pressing component 3 is tilted, thereby simulating a situation in which the user presses the button 120 from an oblique direction.

[0056] Specifically, the momentary break detection device also includes a pressure mechanism 4, a pressure end of which is connected to the pressing component 3, and is configured to apply abutment force to the pressing component 3 after the pressing component 3 abuts against the button 120, and an angle is provided between the abutment force and the travel path of the button 120.

[0057] Furthermore, the pressing component 3 includes a frame 41, a pressure component 42 and an adjustment component 43, the frame 41 can move in the horizontal direction; the connection end 32 of the pressing component 3 is rotationally connected to the frame 41, and the pressure component 42 is arranged between the pressing end 31 of the pressing component 3 and the frame 41; the adjustment component 43 is connected to the pressure component 42, and the adjustment component 43 is configured to adjust the abutment force.

[0058] It can be understood that when performing a momentary break detection on the switch 100, the detection fixture 1 carrying the switch 100 to be detected is moved between the detection mechanism 2 and the pressing component 3, and then the switch 100 is connected to the detection circuit through the probe 23, so that the switch 100 can be detected for a momentary break through the detection mechanism 2. Before performing a momentary break detection on the switch 100, the control frame 41 is moved close to the button 120, so that the pressing component 3 can be driven close to the button 120. When the pressing end 31 abuts against the button 120, under the action of the adjustment component 43, an abutting force can be applied to the pressing component 3, so that the pressing component 3 can be rotated, thereby simulating a user pressing the button 120 from the side to detect unqualified products, thereby improving the accuracy of the momentary break detection of the switch 100 and thus improving the user experience.

[0059] Specifically, the adjustment assembly 43 includes a connecting rod 431 and a limiting platform 432. The connecting rod 431 is connected to the pressing component 3, and the length direction of the connecting rod 431 is perpendicular to the moving direction of the pressing component 3. The connecting rod 431 is overlapped on the limiting platform 432. The limiting platform 432 includes a plane section 4321 and an inclined section 4322. The inclined section 4322 is located in the downstream section of the movement of the connecting rod 431. It can be understood that the connecting rod 431 is overlapped on the plane section 4321. When the frame 41 moves, the connecting rod 431 will move with it. When the connecting rod 431 moves to the inclined section 4322, the axis height of the connecting rod 431 changes, so that the pressing component 3 can be rotated, and then the pressure-applying component 42 can apply an oblique abutting force to the pressing end 31.

[0060] It should be noted that when the connecting rod 431 moves to the end of the plane section 4321, the pressing end 31 contacts the button 120. The length of the plane section 4321 is determined according to actual working conditions and will not be elaborated here.

[0061] It should also be noted that, in the horizontal direction, the inclined surface section 4322 can be inclined upward to press the button 120 upward, or can be inclined downward to press the button 120 downward. This arrangement facilitates simulating a user pressing the button 120 from different directions when performing a momentary break detection on the switch 100. It should further be noted that the inclination direction and inclination angle of the inclined surface section 4322 are set according to actual working conditions and are not specifically limited here.

[0062] Furthermore, a limiting hole 411 is provided on the frame 41, the connecting rod 431 passes through the limiting hole 411, and the diameter of the limiting hole 411 is larger than the diameter of the limiting hole 411; it can be understood that the connecting rod 431 is always in the limiting hole 411 during the movement on the limiting platform 432. Such a setting is convenient for further limiting the rotation angle of the pressing component 3 to avoid the pressing end 31 swinging at an excessively large angle and causing the button 120 to break.

[0063] In order to keep the connecting rod 431 in a horizontal state when it is in the plane section 4321, in this embodiment, a rolling portion 4311 is provided at the end of the connecting rod 431 and is slidably arranged on the limiting platform 432. The rolling portion 4311 is coaxially arranged with the connecting rod 431, and the diameter of the rolling portion 4311 is larger than the diameter of the connecting rod 431. In some other feasible embodiments, in order to maintain the smooth operation of the connecting rod 431, two limiting platforms 432 are provided, and the two limiting platforms 432 are symmetrically arranged about the pressing component 3. Correspondingly, the connecting rod 431 is provided with a rolling portion 4311 at both ends.

[0064] In particular, the rolling part 4311 is detachably connected to the connecting rod 431. This arrangement facilitates the selection of a rolling part 4311 of a suitable size according to actual working conditions, so as to control the rotation amplitude of the pressing component 3. In addition, the rolling part 4311 is preferably a ball, and the ball is sleeved on the end of the connecting rod 431.

[0065] Preferably, the inclined surface section 4322 is arranged to be inclined downward. To ensure that the pressing component 3 can apply sufficient abutment force to the button 120, in this embodiment, the pressure component 42 is an elastic member, which is compressed and arranged between the pressing component 3 and the frame 41, so as to have elastic potential energy to restore the deformation after the connecting rod 431 moves to the inclined surface section 4322. In actual application, after the connecting rod 431 moves to the inclined surface section 4322, the frame 41 continues to move in the horizontal direction. At this time, the connecting rod 431 moves along the inclined surface section 4322, so that the pressing component 3 rotates, and the elastic member restores the deformation, so that it can apply a force to the pressing component 3, so as to ensure that the pressing end 31 can press the button 120 to complete the instantaneous break detection of the switch 100. The elastic member is preferably a compression spring.

[0066] In particular, the pressing end 31 is provided with a step surface, and the step surface can be fitted with two adjacent side surfaces of the button 120. Such a configuration can prevent the pressing end 31 from falling off when the button 120 is pressed.

[0067] In this embodiment, the detection mechanism 2 further includes a driving member 21 and a detection unit, the probe 23 is disposed at the driving end of the driving member 21, and the driving member 21 is configured to push the probe 23 to abut against the terminal 110; the detection unit is electrically connected to the detection circuit to perform a momentary disconnection detection on the switch 100. It can be understood that when the switch 100 moves to the detection station, the probe 23 is controlled by the driving member 21 to connect to the terminal 110, so that the switch 100 is connected to the detection circuit, thereby facilitating the detection unit to detect it.

[0068] It should be noted that the detection unit uses an existing instantaneous break detection unit, which will not be described in detail here.

[0069] Furthermore, the detection mechanism 2 further includes a positioning assembly 22, which is disposed between the driving member 21 and the switch 100 so that the probe 23 is disposed relative to the terminal 110. It is understandable that when the switch 100 is transported to the detection station, the positioning assembly 22 can be used to position the terminal 110 and the probe 23, thereby further improving the detection efficiency.

[0070] Specifically, the positioning assembly 22 includes a first positioning member 221 and a second positioning member 222. The first positioning member 221 is disposed at the driving end of the driving member 21, and the second positioning member 222 is disposed at the switch 100. The first positioning member 221 is adapted to the second positioning member 222. Exemplarily, the first positioning member 221 is a positioning hole, and the second positioning member 222 is a positioning pin. In some other feasible embodiments, the positioning assembly 22 may also be other existing positioning elements, which will not be described in detail herein.

[0071] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
