Description

Technical Field

[0001] This utility model relates to the field of inverter panel button testing, specifically to an inverter panel button testing fixture. Background Technology

[0002] like Figure 1 The buttons on inverter panel 200 and inverter panel 300 shown need to be tested. In existing technology, this is typically done using an electrical testing system electrically connected to the inverter panel, in conjunction with a button testing fixture. The existing button testing fixture includes multiple pressing cylinders, each with a pressing block at its output end. The positions of the pressing cylinders correspond one-to-one with the button positions. During testing, the pressing cylinders drive the pressing blocks to press the buttons. The electrical testing system, electrically connected to the inverter panel, then performs electrical tests on the pressed buttons. The response of the electrical testing system determines whether the button functions correctly.

[0003] However, existing inverter panel button testing fixtures have the following problems: There are too many buttons on the inverter panel, and current technology requires setting up a pressing cylinder for each button, which occupies a lot of space. Additionally, ... Figure 1 The diagram shows multiple buttons 203 arranged in a ring, with short distances between each button 203. If multiple pressing cylinders are installed... Figure 1 The button shown corresponds to button 203. Interference can easily occur between the pressing cylinders, affecting the pressing test efficiency. Utility Model Content

[0004] The technical solution adopted by this utility model to solve its technical problem is: to provide a test fixture for inverter panel buttons, comprising:

[0005] A platform, wherein the platform is provided with cavities for placing inverter panel one and inverter panel two;

[0006] The pressing module includes a mounting plate, a rotary motor, a pressing cylinder one, and a pressing cylinder two. The output end of the rotary motor is equipped with a transmission module, which is connected to a carrier frame. The carrier frame is equipped with a pressing block two. The pressing cylinder one corresponds to button one, the pressing cylinder two corresponds to button two, and the pressing block two corresponds to button three. The output ends of both pressing cylinder one and pressing cylinder two are equipped with pressing blocks one. The rotary motor drives the pressing block two to rotate through the transmission module.

[0007] A lifting module is provided with a frame at its output end, and a pressing module is mounted on the frame. The lifting module is used to drive the pressing module to move.

[0008] Furthermore, the transmission module includes a first gear, a second gear, and a third gear. The first gear is coaxially fixed with the output end of the rotating motor. The second gear is located between the first gear and the third gear, and the second gear meshes with both the first gear and the third gear. The carrier is connected to the third gear, and the output end of the second pressing cylinder passes through the inner hole of the third gear.

[0009] Furthermore, it also includes a slide rail and a telescopic cylinder. The platform and the output end of the telescopic cylinder are connected. The telescopic cylinder is used to drive the platform to slide on the slide rail.

[0010] Furthermore, the frame is equipped with a movable cylinder, and the pressing module is provided in two sets. The two sets of pressing modules correspond to the frequency converter panel one and the frequency converter panel two, respectively. The output end of the movable cylinder is connected to the pressing module corresponding to the frequency converter panel two, and the movable cylinder is used to drive the pressing module to move.

[0011] Furthermore, the frame is provided with a sliding groove, and the pressing module of the strain frequency converter panel two is slidably disposed in the sliding groove.

[0012] Furthermore, the frame is provided with positioning posts, and the platform is provided with positioning holes that are compatible with the positioning posts. When the lifting module drives the frame to move, the positioning posts are inserted into the positioning holes.

[0013] Furthermore, the platform is equipped with a handle.

[0014] The beneficial effects of this utility model are as follows: By setting up a rotating motor and a lifting module, when dealing with multiple buttons three that are close together, the lifting module drives the pressing block two to rise and fall until it contacts the buttons three. The rotating motor drives the pressing block two to rotate through the transmission module, so that multiple buttons three can be pressed separately. This reduces the space occupied by the pressing module as a whole, and also reduces the interference between the multiple pressing cylinders caused by the short distance between the buttons three, which affects the pressing test efficiency.

Detailed Implementation

[0023] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Please refer to Figure 2 and Figure 5This utility model provides a test fixture 100 for inverter panel buttons, including a platform 10, a pressing module 20 and a lifting module 43. The platform 10 is provided with a cavity 11 for placing inverter panel 200 and inverter panel 300. The pressing module 20 includes a mounting plate 21, a rotating motor 22, a pressing cylinder 1 23, and a pressing cylinder 24. The output end of the rotating motor 22 is provided with a transmission module 25, which is connected to a carrier frame 26. The carrier frame 26 is provided with a pressing block 27. The pressing cylinder 1 23 corresponds to button 1 201, the pressing cylinder 24 corresponds to button 202, and the pressing block 27 corresponds to button 3 203. The output ends of the pressing cylinders 1 23 and 24 are both provided with pressing blocks 1 231. The rotating motor 22 drives the pressing block 27 to rotate through the transmission module 25. The output end of the lifting module 43 is provided with a frame 40, and the pressing module 20 is mounted on the frame 40. The lifting module 43 is used to drive the pressing module 20 to move.

[0025] Specifically, in this embodiment, the lifting module 43 can be a cylinder or a lead screw drive structure in the prior art; in this embodiment, a cylinder is selected. The starting height of the bottom end of the second pressing block 27 is lower than the starting height of the bottom end of the first pressing block 231. During the pressing test, the lifting module 43 drives the pressing module 20 to move until the second pressing block 27 moves to contact the third pressing button 203 and presses the third pressing button 203 downward. The rotating motor 22 drives the second pressing block 27 to rotate, thereby pressing the multiple third pressing buttons 203 that are arranged in a ring. The first pressing cylinder 23 and the second pressing cylinder 24 respectively drive the corresponding first pressing block 231 to press the first pressing button 201 and the second pressing button 202.

[0026] By using the rotating motor 22 and the lifting module 43, when targeting buttons 3 203 with short spacing, the lifting module 43 drives the pressing block 27 to rise and fall until it contacts the button 3 203. The rotating motor 22 drives the pressing block 27 to rotate through the transmission module 25, which can press multiple buttons 3 203 separately. This reduces the space occupied by the pressing module 20 and also reduces the interference between multiple pressing cylinders caused by the short spacing between the corresponding buttons 3 203, thus reducing the impact on the pressing test efficiency.

[0027] Please refer to Figure 6 The transmission module 25 includes a first gear 251, a second gear 252, and a third gear 253. The first gear 251 is coaxially fixed with the output end of the rotating motor 22. The second gear 252 is located between the first gear 251 and the third gear 253, and the second gear 252 meshes with both the first gear 251 and the third gear 253. The carrier 26 is connected to the third gear 253. Since the second button 202 is located at the center of the circular track where multiple third buttons 203 are located, the output end of the pressing cylinder 24 passes through the inner hole of the third gear 253.

[0028] Specifically, the mounting plate 21 is provided with a mounting bracket 211 for fixing the second pressing cylinder 24, and the second gear 252 and the third gear 253 are rotatably connected to the mounting plate 21.

[0029] Please refer to Figure 3 The inverter panel button test fixture 100 also includes a slide rail 30 and a telescopic cylinder 31. The platform 10 and the output end of the telescopic cylinder 31 are connected. The telescopic cylinder 31 is used to drive the platform 10 to slide on the slide rail 30.

[0030] Please refer to Figure 3 and Figure 4 The frame 40 is equipped with a movable cylinder 41, and the pressing module 20 is provided in two sets. The two sets of pressing modules 20 respectively correspond to the frequency converter panel 1 200 and the frequency converter panel 2 300. The output end of the movable cylinder 41 is connected to the pressing module 20 corresponding to the frequency converter panel 2 300. The movable cylinder 41 is used to drive the pressing module 20 to move.

[0031] Specifically, there are two layout options for the buttons 201 on the inverter panel 2 300, and therefore, there are two corresponding layout options for the pressing cylinders 23 on the mounting plate 21 of the inverter panel 2 300 (only one layout option of the inverter panel 2 300 is shown in the figure). When the layout of the buttons 201 on the inverter panel 2 300 placed in the cavity 11 changes, the mounting plate 21 is moved by the moving cylinder 41, so that the pressing cylinders 23 on the mounting plate 21, which are consistent with the current layout of the buttons 201, move to correspond with the inverter panel 200.

[0032] Specifically, the frame 40 is provided with a sliding groove 42, and the pressing module 20 of the strain frequency converter panel 2 300 is slidably disposed in the sliding groove 42.

[0033] Please refer to Figure 4 and Figure 5 The frame 40 is provided with a positioning column 44, and the platform 10 is provided with a positioning hole 13 that matches the positioning column 44. When the lifting module 43 drives the frame 40 to move, the positioning column 44 is inserted into the positioning hole 13.

[0034] The positioning pins 44 and positioning holes 13 ensure that the frame 40 and the platform 10 are relatively fixed during the pressing test, preventing relative movement and thus minimizing the impact on the pressing test efficiency. Simultaneously, the positioning holes 13 and positioning pins 44 facilitate mutual positioning of the platform 10 and the frame 40, making it easier to determine their relative positions.

[0035] Please refer to Figure 5The platform 10 is equipped with a handle 12, which is designed to facilitate the staff to remove the platform 10 from the slide rail 30 after the test is completed.
