Description

Technical Field

[0001] This utility model belongs to the technical field of relay processing equipment, specifically relating to an online contact pressure adjustment mechanism. Background Technology

[0002] In the manufacturing process of electronic components such as relays, switches, and connectors, refer to Figure 1 A relay mainly consists of a moving spring 1, a stationary spring 2, and a pin 3. The moving spring 1 and stationary spring 2 are mounted on pin 3. The contact pressure between the moving spring 1 and stationary spring 2 is a crucial performance parameter, directly affecting contact resistance, switching reliability, product lifespan, and vibration resistance. Insufficient pressure can lead to poor contact, causing arcing, excessive temperature rise, or even open circuit; excessive pressure can cause excessive stress relaxation of the material, accelerated wear, and excessive burden on the operating mechanism. Therefore, the pressure needs to be tested and adjusted before welding.

[0003] Current adjustment mechanisms are either integrated with the welding equipment and directly use cylinders to adjust the position of the moving spring 1, resulting in low adjustment accuracy, or each contact point is tested separately, which not only occupies a lot of space but also has low efficiency, poor versatility, and is inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to provide an online contact pressure adjustment mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A contact pressure online adjustment mechanism includes a frame, on which a drive support assembly, an adjustment assembly, and a detection feedback assembly are disposed;

[0007] The drive support assembly is mounted on the surface of the frame. A set of symmetrically arranged adjustment components and a set of symmetrically arranged detection feedback components are provided on one side of the drive support assembly. The adjustment components and the detection feedback components are arranged adjacent to each other.

[0008] By adopting the above technical solution: during the inspection, the product to be welded is placed on the surface of the drive support assembly, and moved under the adjustment assembly and the detection feedback assembly by the drive support assembly. Then, the position of the moving spring is adjusted by simultaneously activating two sets of adjustment assemblies, and the detection feedback assembly is used to detect whether the adjustment is in place. After the adjustment is completed, it is conveyed to the next station for welding.

[0009] Preferably, the adjustment assembly includes a first driving element, a first conductive element, and a hook. The first driving element is mounted on the surface of the frame, the output end of the first driving element is connected to the first conductive element, and the end of the first conductive element away from the first driving element is connected to the hook.

[0010] By adopting the above technical solution: under the drive of the first driving member, the conductive member and the hook move along the length direction of the first driving member, and the position of the moving spring is adjusted by the hook.

[0011] Preferably, the detection feedback component includes a second drive unit, a pressure sensor, and a ejector pin. The second drive unit is mounted on the surface of the frame, the output end of the second drive unit is connected to the pressure sensor, and the other end of the pressure sensor is connected to the ejector pin.

[0012] By adopting the above technical solution: under the drive of the second driving component, the pressure sensor and the ejector pin move, the ejector pin pushes the moving spring and collects the pressure value, and then the position of the moving spring is adjusted by the adjustment component until the pressure is within the set range.

[0013] Preferably, the frame is provided with a second conductive element on one side of the ejector pin.

[0014] By adopting the above technical solution, the second conductive element is used to energize the ejector pin and the pressure sensor to form a circuit, thereby enabling the detection of instantaneous pressure values.

[0016] By adopting the above technical solution: under the drive of the driving cylinder, the bracket drives the adjustment component and the detection feedback component to move along the length of the slide rail until the moving spring located above the fixture contacts the adjustment component and the detection feedback component, which facilitates detection.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] This device utilizes the collaborative operation of the drive support component, adjustment component, and detection feedback component to achieve instantaneous detection of the contact pressure of the product. No manual operation is required. Through real-time adjustment of closed-loop control, pressure dispersion is completely eliminated, ensuring the accuracy of adjustment. Attached Figure Description

Detailed Implementation

[0023] The following will refer to the appendix in the embodiments of this utility model. Figures 2-3 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The specific embodiments described herein are merely used to explain this utility model and are not intended to limit this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Example:

[0025] like Figures 2-3 As shown, this utility model provides an online contact pressure adjustment mechanism, including a frame 4, on which a drive support assembly 5, an adjustment assembly 6, and a detection feedback assembly 7 are arranged. The drive support assembly 5 is installed on the surface of the frame 4. A set of symmetrically arranged adjustment assemblies 6 and a set of symmetrically arranged detection feedback assemblies 7 are arranged on one side of the drive support assembly 5. The adjustment assembly 6 and the detection feedback assembly 7 are arranged adjacent to each other. During the detection, the product to be welded is placed on the surface of the drive support assembly 5 and moved under the drive of the drive support assembly 5. Then, the position of the moving spring 1 is adjusted by simultaneously activating the two sets of adjustment assemblies 6, and the detection feedback assembly 7 detects whether the adjustment is in place. After the adjustment is completed, it is conveyed to the next station for welding.

[0026] The adjustment assembly 6 includes a first driving member 61, a first conductive member 62, and a hook 63. The first driving member 61 is mounted on the surface of the frame 4. The output end of the first driving member 61 is connected to the first conductive member 62. The end of the first conductive member 62 away from the first driving member 61 is connected to the hook 63. Driven by the first driving member 61, the conductive member and the hook 63 move along the length direction of the first driving member 61, and the position of the moving spring 1 is adjusted by the hook 63.

[0027] The detection feedback component 7 includes a second drive component 71, a pressure sensor 72, and a push pin 73. The second drive component 71 is mounted on the surface of the frame 4. The output end of the second drive component 71 is connected to the pressure sensor 72, and the other end of the pressure sensor 72 is connected to the push pin 73. Driven by the second drive component 71, the pressure sensor 72 and the push pin 73 move, pushing the movable spring 1 through the push pin 73 and collecting the pressure value. Then, the position of the movable spring 1 is adjusted by the adjustment component 6 until the pressure is within the set range.

[0028] The frame 4 has a second conductive element 74 on one side of the ejector pin 73. The second conductive element 74 is used to energize the ejector pin 73 and the pressure sensor 72 to form a circuit, thereby enabling the detection of instantaneous pressure values.

[0029] The drive support assembly 5 includes a drive cylinder 51, a slide rail 52, a bracket 53, and a fixture 54. The drive cylinder 51 is mounted on one side of the frame 4. The slide rail 52 is mounted on the surface of the frame 4, and the bracket 53 is slidably mounted on the surface of the slide rail 52. The output end of the drive cylinder 51 is connected to the bracket 53. The adjustment assembly 6 and the detection feedback assembly 7 are both mounted above the bracket 53. The fixture 54 is located below the bracket 53 on the frame 4. Driven by the drive cylinder 51, the bracket 53 moves the adjustment assembly 6 and the detection feedback assembly 7 along the length of the slide rail 52 until the moving spring 1 located above the fixture 54 contacts the adjustment assembly 6 and the detection feedback assembly 7, facilitating detection.

[0030] When both the first conductive element 62 and the second conductive element 74 are energized, the moving spring 1 on the left side contacts the stationary spring 2, thus forming a circuit between the first conductive element 62 and the second conductive element 74 on the left side. When the moving spring 1 on the right side contacts the stationary spring 2, the first conductive element 623 on the right side contacts the second conductive element 74, thus forming a circuit.

[0031] In this embodiment, both the first drive component 61 and the second drive component 71 adopt linear ball bearing guide type slides, and the pressure sensor 72 adopts high precision mN level, which can ensure more accurate acquisition of pressure value at the moment of disconnection and improve the contact pressure adjustment qualification rate. The first conductive component 62 and the second conductive component 74 are made of brass, which has good conductivity and is more sensitive to the acquisition of on / off signals. The hook 63 is made of chromium zirconium copper, which ensures that the product is not scratched during the pressure adjustment process.

[0032] When the fixture 54 is placed below the online contact pressure adjustment mechanism, the drive cylinder 51 retracts, and the online contact pressure adjustment mechanism is pressed down. The first conductive element 62 on the left side drives the hook 63 to hook the moving spring 1 to the set position. The moving spring 1 rotates clockwise around the pin 3 and contacts the stationary spring 2, forming contact pressure. The first conductive element 62 on the left side and the second conductive element 74 form a circuit. The first conductive element 62 on the right side drives the hook 63 to hook the moving spring 1 to the set position. The moving spring 1 rotates clockwise around the pin 3 and contacts the stationary spring 2, forming contact pressure. The first conductive element 62 on the right side and the second conductive element 74 form a circuit.

[0033] The second driving component 71 drives the pressure sensor 72 and the ejector pin 73 to push the moving spring 1 forward, collecting the pressure value at the moment when the first conductive component 62 and the second conductive component 74 are disconnected. If the pressure is too high, the hook 63 is pulled back a compensation distance and the pressure value is detected again. If the pressure is too low, the hook 63 is pulled back a compensation distance and the pressure value is detected again until the pressure is within the set range.

[0034] In summary, this device utilizes the collaborative operation of the drive support component 5, the adjustment component 6, and the detection feedback component 7 to achieve instantaneous detection of the contact pressure of the product. No manual operation is required. Through real-time adjustment of closed-loop control, pressure dispersion is completely eliminated, ensuring the accuracy of adjustment.

[0035] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
