Description

Technical Field

[0001] This utility model relates to the field of button testing technology, specifically a spring-loaded button testing module. Background Technology

[0002] The electronics manufacturing industry is developing rapidly, and many electronic products have buttons, such as keyboards, calculators, and mobile phones. These electronic products need to undergo various button tests when they leave the factory, such as button life test, single button multi-frequency test, and multi-button alternation test.

[0003] The prior art (authorization announcement number: CN222336743 U) is a high-resilience rubber key testing device, which facilitates the rapid loading and unloading of keyboards. It can utilize multiple sets of pressing heads in a single row on the lower end face of the key testing mounting plate for simultaneous pressing tests, which is faster, more stable and reliable. It is also convenient and flexible to adjust the number of pressing test heads, making it more convenient and practical.

[0004] The application uses a telescopic cylinder to lower the rubber head to complete the test, but this method has certain shortcomings. Buttons are used in electronic products, and the electrical components inside these products generate heat when they are working. Therefore, the environment in which the button is located has a certain temperature. Testing at room temperature cannot detect the correct data of the button. Therefore, a spring-loaded button testing module is proposed. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a spring-loaded button testing module to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a spring-loaded button testing module, including a test platform, an L-plate fixed at the top and near the edge of the test platform, a test component for storing buttons fixed at the top of the test platform, and a detection head for reciprocating pressing test of the buttons in the test component provided below the L-plate.

[0007] The test assembly includes a test frame fixed to the upper surface of the test platform. An inner liner is movably fitted inside the test frame. The top of the inner liner has multiple sets of equally spaced grooves along its length. Each set of grooves contains a strip. The top of the strip has multiple sets of constraint plates fixed along its length. A heating frame capable of supplying hot air to the test frame is provided on one side of the test frame. An air pump connected to the heating frame is mounted on the upper surface of the test platform outside the L-plate.

[0008] As a preferred technical solution, a T-shaped bracket is fixed on the front surface of the L-plate above the test platform, a positioning plate is provided below the T-shaped bracket, and a stroke cylinder capable of driving the T-shaped bracket to reciprocate up and down is installed on the upper surface of the T-shaped bracket.

[0009] As a preferred technical solution, the number of detection heads is multiple and distributed in a rectangular array below the positioning plate. The top of each detection head is connected to an outer cylinder by a thread, and the top of the outer cylinder is fixed to the bottom of the positioning plate. The detection head is made of rubber material.

[0010] As a preferred technical solution, the lower inner wall of the test frame is fixed with three sets of abutment strips, and the front and rear surfaces of the test frame are provided with multiple sets of heat dissipation holes that correspond to the internal structure.

[0011] As a preferred technical solution, the bottom of the inner lining plate is provided with multiple sets of clearance grooves, and the multiple sets of clearance grooves are staggered with the grooves.

[0012] As a preferred technical solution, the two adjacent sets of constraint plates and the inner wall of the groove form a cavity that can store the case, and the size of the plate is adapted to the groove.

[0013] As a preferred technical solution, the three sets of abutment strips and relief grooves are arranged in a vertically intersecting shape.

[0014] In summary, the present invention has the following main advantages:

[0015] This invention delivers hot air into the test frame through a heating frame. The abutment bar creates a cavity between the bottom of the inner liner and the lower inner wall of the test frame, allowing the hot air to remain in the cavity for a certain period of time. The hot air also flows into the clearance groove (i.e., from both sides of the groove) and the bottom to heat the button, simulating the environment inside an electronic product, thus making the measured structure more accurate.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] The embodiments of this utility model will be described below based on its overall structure.

[0026] A spring-loaded button testing module, such as Figures 1 to 6 As shown, the test platform 100 is included. An L-plate 110 is fixed at the top of the test platform 100 and near the edge. A test assembly 200 for storing buttons is fixed at the top of the test platform 100. A detection head 150 for reciprocating pressing test of the buttons in the test assembly 200 is provided below the L-plate 110.

[0027] The test assembly 200 includes a test frame 230 fixed to the upper surface of the test bench 100. An inner liner 270 is movably fitted inside the test frame 230. The top of the inner liner 270 has multiple sets of equally spaced grooves 271 along its length. Each set of grooves 271 has a strip 260. The top of the strip 260 has multiple sets of constraint pieces 261 fixed along its length. A heating frame 220 capable of supplying hot air to the test frame 230 is provided on one side of the test frame 230. An air pump 210 connected to the heating frame 220 is installed on the upper surface of the test bench 100 outside the L plate 110.

[0028] The front surface of L plate 110 is fixed with a T-shaped bracket 140 above the test bench 100. A positioning plate 120 is provided below the T-shaped bracket 140. A stroke cylinder 130 that can drive the T-shaped bracket 140 to reciprocate and lift is installed on the upper surface of the T-shaped bracket 140.

[0029] Three sets of abutment strips 240 are fixed on the lower inner wall of the test frame 230. Multiple sets of heat dissipation holes 250 with internal structure are opened on the front and rear surfaces of the test frame 230. The three sets of abutment strips 240 and the relief groove 272 are perpendicular to each other.

[0030] The bottom of the inner lining plate 270 has multiple sets of clearance grooves 272, and the multiple sets of clearance grooves 272 are staggered with the grooves 271.

[0031] It is worth noting that the stroke cylinder 130 and the air pump 210 are connected to the external power supply by wires, and the heating frame 220 is equipped with a heating wire for heating the air, and the heating temperature can meet the temperature of the button inside the electronic product. The upper limit of its heating temperature is achieved by existing technology.

[0032] The buttons to be tested are placed one by one into the cavity formed by the two sets of constraint plates 261. The stroke cylinder 130 can be controlled to work, and its output end can push the positioning plate 120 to lower, so that the detection head 150 extends into the groove 271 and contacts the button to achieve the pressing effect. Then it returns to the original position and lowers again. This process is repeated to test the player. The button pressing test can be performed within a specified time (or the number of times the stroke cylinder 130 is raised and lowered can be controlled to test the case). Finally, the test result of the case can be obtained.

[0033] While testing the buttons, the vacuum pump 210 draws outside air into the heating frame 220. The heating wire in the heating frame 220 heats the air and then delivers it to the test outer frame 230, which is located at the bottom of the inner liner 270. The abutment 240 creates a cavity between the bottom of the inner liner 270 and the lower inner wall of the test outer frame 230. The abutment 240 also divides the cavity, allowing the hot air to remain in the cavity for a certain period of time. The hot air then flows into the clearance groove 272 and heats the buttons from both sides and the bottom of the groove 271. This simulates the environment inside an electronic product, making the measured structure more accurate.

[0034] Please refer to this carefully. Figure 6 The number of detection heads 150 is in multiple groups and distributed in a rectangular array below the positioning plate 120. The top of each group of detection heads 150 is connected to an outer cylinder 151 by a thread. The top of the outer cylinder 151 is fixed to the bottom of the positioning plate 120. The detection heads 150 are made of rubber.

[0035] The detection head 150 is made of rubber to simulate the pressing of a human finger. The detection head 150 is threadedly connected to the outer cylinder 151, allowing for flexible replacement of detection heads of different lengths. In conjunction with the stroke cylinder 130, it can test buttons of different thicknesses.

[0036] Please refer to this carefully. Figure 4 The two adjacent sets of constraint plates 261 and the inner wall of the groove 271 form a cavity that can store the case, and the size of the strip 260 is adapted to the groove 271.

[0037] The slats 260 can be flexibly removed from the grooves 271 and replaced with slats 260 that fit the dimensions of the case (the spacing between two adjacent sets of constraint plates 261 can be increased or decreased to meet the case dimensions within a certain range).

[0038] In use, the buttons to be tested are placed one by one into the cavity formed by the two sets of constraint plates 261. The stroke cylinder 130 can be controlled to work, and its output end can push the positioning plate 120 to lower, so that the detection head 150 extends into the groove 271 and contacts the button to achieve the pressing effect. Then it returns to the original position and lowers again. This process is repeated to test the player. The button pressing test can be performed within a specified time (or the number of times the stroke cylinder 130 is raised and lowered can be controlled to test the case). Finally, the test result of the case can be obtained.

[0039] While testing the buttons, the vacuum pump 210 draws outside air into the heating frame 220. The heating wire in the heating frame 220 heats the air and then delivers it to the test outer frame 230, which is located at the bottom of the inner liner 270. The abutment 240 creates a cavity between the bottom of the inner liner 270 and the lower inner wall of the test outer frame 230. The abutment 240 also divides the cavity, allowing the hot air to remain in the cavity for a certain period of time. The hot air then flows into the clearance groove 272 and heats the buttons from both sides and the bottom of the groove 271. This simulates the environment inside an electronic product, making the measured structure more accurate.
