Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and more specifically, to a dual-station alternating backlight keyboard light effect testing machine. Background Technology

[0002] A backlit keyboard is a keyboard with backlighting. It uses high-brightness light-emitting diodes (LEDs) embedded in the keyboard slot. When the computer receives a keystroke command, it controls the keyboard to turn on the LEDs, making the keys or panel light up for easy use at night.

[0003] Currently, the production process of backlit keyboards requires the use of testing machines to detect light effects and determine whether the keyboard keys or panels are illuminating normally. However, most existing light effect testing machines are usually single-station or multi-station testing machines. When backlit keyboards are tested at a single station, the light effect testing machine needs to return to its initial position after testing each backlit keyboard before it can place the next product. The equipment wastes a lot of time during the reset process, resulting in low testing efficiency. When backlit keyboards are tested at a multi-station, each testing station requires a certain amount of space, resulting in a large equipment size and inconvenience in placement. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a dual-station alternating backlight keyboard light effect testing machine. This aims to solve the problems of existing light effect testing machines, which are typically single-station or multi-station testing machines. Specifically, when using single-station testing, the light effect testing machine needs to return to its initial position after testing each backlight keyboard before placing the next product, wasting considerable time during the reset process and resulting in low testing efficiency. Conversely, when using multi-station testing, each testing station requires a certain amount of space, leading to a large device size and inconvenient placement.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution:

[0008] A dual-station alternating backlit keyboard light effect testing machine includes a frame, a fixed base fixedly connected inside the frame, a rodless cylinder guide module fixedly connected to one side of the fixed base, an upper testing platform slidably connected to the top of the fixed base and fixedly connected to the rodless cylinder guide module, a lower slide plate slidably connected inside the fixed base, and the lower slide plate and the upper testing platform are arranged in an alternating manner, a lifting rod assembly slidably inserted inside the lower slide plate, a lifting testing platform fixedly connected to the top of the lifting rod assembly, and the lifting testing platform is located above the lower slide plate and corresponds to the upper testing platform, positioning fixtures fixedly connected to the top of both the lifting testing platform and the upper testing platform, a lead screw lifting module fixedly connected inside the frame, a testing camera mounted on the lead screw lifting module and corresponding to two positioning fixtures, a linkage mechanism between the upper testing platform and the lower slide plate for controlling the simultaneous movement of the upper testing platform and the lower slide plate, and a lifting mechanism between the fixed base and the lifting testing platform for controlling the lifting testing platform to move up and down.

[0009] As a preferred embodiment of this utility model, the linkage mechanism includes a pulley assembly, a belt, and two connecting blocks. The pulley assembly is rotatably connected to one side wall of the fixed base, and the belt drive is connected to the pulley assembly. The two connecting blocks are respectively fixedly connected to the upper detection platform and the lower slide plate, and both connecting blocks are fixedly connected to the belt in an alternating vertical distribution.

[0010] As a preferred embodiment of this utility model, the lifting mechanism includes a fixed plate, a lifting groove, a lifting rod, and rollers. The fixed plate is fixedly connected to a fixed base. The lifting groove is opened at one end of the fixed plate. The lifting rod is fixedly connected to the bottom end of the lifting detection platform and moves through the lower slide plate. The rollers are rotatably connected to the bottom of the lifting rod and are slidably connected to the lifting groove.

[0011] As a preferred embodiment of this utility model, the top of the fixed base is fixedly connected to a first slide rail group, and the upper detection platform is slidably connected to the first slide rail group.

[0012] In a preferred embodiment of this utility model, a second slide rail assembly is fixedly connected inside the fixed base, and the lower slide plate is slidably connected to the second slide rail assembly.

[0014] 3. Beneficial effects

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] (1) In this solution, when testing the light effect of the backlit keyboard, the rodless cylinder guide module controls the upper testing platform to reciprocate, so that the upper testing platform drives the backlit keyboard into the rack for light effect testing through the positioning fixture. During the movement of the upper testing platform, the lifting testing platform reciprocates simultaneously through the linkage mechanism and the lower slide plate. The lifting testing platform and the upper testing platform move in opposite directions. When they are close, they are crossed by the lifting mechanism. After the lifting testing platform and the upper testing platform cross, they automatically return to the initial height corresponding to the testing camera when they enter the rack. The testing camera monitors the backlight in the positioning fixture on the lifting testing platform. The keyboard undergoes a light effect test. The testing machine consists of two stations: an upper testing platform and a lifting testing platform. The upper testing platform and the lifting testing platform are linked by a linkage mechanism and a lifting mechanism. Driven by a rodless cylinder guide module, they can alternately enter the frame to correspond with the testing camera for light effect testing. When one backlit keyboard is removed after testing, another backlit keyboard is simultaneously transported into the testing machine. The second backlit keyboard is transported in during the interval when the equipment resets and sends out the first backlit keyboard. This effectively improves work efficiency. Moreover, both stations are on a fixed base, which does not require additional placement space, making the overall size of the testing machine small and easy to place. Attached Figure Description

[0026] Example:

[0027] Please see Figure 1-4 A dual-station alternating backlight keyboard light effect testing machine includes a frame 1, a fixed base 2 fixedly connected inside the frame 1, a rodless cylinder guide module 3 fixedly connected to one side of the fixed base 2, an upper testing platform 4 slidably connected to the top of the fixed base 2, and the upper testing platform 4 fixedly connected to the rodless cylinder guide module 3; a lower slide plate 5 slidably connected inside the fixed base 2, and the lower slide plate 5 and the upper testing platform 4 are arranged in an alternating vertical arrangement; a lifting rod assembly 6 slidably inserted inside the lower slide plate 5; a lifting testing platform 7 fixedly connected to the top of the lifting rod assembly 6; and the lifting testing platform 7... The upper side of the lower slide plate 5 corresponds to the upper inspection platform 4. The top of both the lifting inspection platform 7 and the upper inspection platform 4 are fixedly connected to positioning fixtures 8. The screw lifting module 9 is fixedly connected inside the frame 1. The screw lifting module 9 is equipped with an inspection camera 10, and the inspection camera 10 corresponds to the two positioning fixtures 8. A linkage mechanism is provided between the upper inspection platform 4 and the lower slide plate 5. The linkage mechanism is used to control the upper inspection platform 4 and the lower slide plate 5 to move simultaneously. A lifting mechanism is provided between the fixed base 2 and the lifting inspection platform 7. The lifting mechanism is used to control the lifting inspection platform 7 to move up and down.

[0028] In this embodiment, the rodless cylinder guide module 3 is fixed to one side of the fixed base 2, and the upper test platform 4 is fixed on the guide slider of the rodless cylinder guide module 3. Positioning fixtures 8 are provided on both the upper test platform 4 and the lifting test platform 7 for positioning the backlight keyboard. When testing the light effect of the backlight keyboard, the test camera 10 is adjusted to the height corresponding to the two positioning fixtures 8 by the lead screw lifting module 9. The rodless cylinder guide module 3 controls the upper test platform 4 to reciprocate on the fixed base 2. At the same time, the linkage mechanism drives the lower slide plate 5 to reciprocate as the upper test platform 4 moves. The lower slide plate 5 drives the lifting test platform 7 to reciprocate through the lifting rod assembly 6. The lifting mechanism controls the lifting test platform 7 to move up and down during the reciprocating motion, so that the lifting test platform 7 and the upper test platform 4 alternate up and down during the reciprocating movement. Finally, the two positioning fixtures 8 and the test camera 10 are alternately corresponded. The backlight keyboards are placed in the two positioning fixtures 8 respectively, and the test camera 10 performs light effect testing on each backlight keyboard that enters the rack 1.

[0029] Specifically, the linkage mechanism includes a pulley assembly 111, a belt 112, and two connecting blocks 113. The pulley assembly 111 is rotatably connected to one side wall of the fixed base 2. The belt 112 is drivenly connected to the pulley assembly 111. The two connecting blocks 113 are respectively fixedly connected to the upper detection platform 4 and the lower slide plate 5, and both connecting blocks 113 are fixedly connected to the belt 112 in an alternating vertical distribution.

[0030] In this embodiment, during the reciprocating motion of the upper testing platform 4, a connecting block 113 drives the belt 112 to move on the pulley assembly 111. The belt 112 drives another connecting block 113 to move in the opposite direction. The other connecting block 113 drives the lower slide plate 5 to reciprocate in the fixed seat 2 in the opposite direction to the upper testing platform 4.

[0031] Specifically, the lifting mechanism includes a fixed plate 121, a lifting groove 122, a lifting rod 123, and a roller 124. The fixed plate 121 is fixedly connected to the fixed base 2. The lifting groove 122 is opened on one side of the fixed plate 121. The lifting rod 123 is fixedly connected to the bottom of the lifting detection platform 7 and moves through the lower slide plate 5. The roller 124 is rotatably connected to the bottom of the lifting rod 123 and slides within the lifting groove 122.

[0032] In this embodiment, during the reciprocating movement of the lower slide plate 5, the lifting detection platform 7 is driven by the lifting rod assembly 6. The lifting detection platform 7 is at the same height as the upper detection platform 4 at the initial height. When the upper detection platform 4 and the lifting detection platform 7 are close to each other, the roller 124 will slide to the downward recess of the lifting groove 122 on the fixed plate 121. Through the connection between the lifting rod 123 and the lifting detection platform 7, the lifting detection platform 7 moves down and passes under the upper detection platform 4, forming an intersection between the upper detection platform 4 and the lifting detection platform 7. After the intersection is completed, the upper detection platform 4 moves to the rear of the fixed base 2, and the lower slide plate 5 drives the lifting detection platform 7 into the frame 1. The roller 124 restores the lifting detection platform 7 to the initial height through the upper part of the lifting groove 122. The backlit keyboard in the positioning fixture 8 on the lifting detection platform 7 corresponds to the detection camera 10 to perform light effect testing.

[0033] Specifically, the top of the fixed base 2 is fixedly connected to the first slide rail group 13, and the upper detection platform 4 is slidably connected to the first slide rail group 13.

[0034] In this embodiment, the upper testing platform 4 moves on the top of the fixed base 2 via the first slide rail group 13, and the first slide rail group 13 keeps the movement of the upper testing platform 4 stable.

[0035] Specifically, a second slide rail assembly 14 is fixedly connected inside the fixed base 2, and the lower slide plate 5 is slidably connected to the second slide rail assembly 14.

[0036] In this embodiment, the lower slide plate 5 moves within the fixed base 2 via the second slide rail group 14, and the second slide rail group 14 keeps the movement of the lower slide plate 5 stable.

[0037] Specifically, a control computer 15 is fixedly connected to one side of the rack 1, and an alarm light 16 is fixedly connected to the top of the rack 1.

[0038] In this embodiment, the rodless cylinder guide module 3, the detection camera 10, and the alarm light 16 are all electrically connected to the control computer 15. The control computer 15 can control the rodless cylinder guide module 3, the detection camera 10, and the alarm light 16. When the detection camera 10 detects a defective product, it will transmit a signal to the control computer 15, and the control computer 15 will issue a warning to the staff through the alarm light 16.

[0039] Working principle: When testing the light effect of the backlit keyboard, the backlit keyboard is placed in the positioning fixture 8 on the lifting test platform 7. The rodless cylinder guide module 3 controls the upper test platform 4 to slide backward on the fixed base 2 and move out of the frame 1. When the upper test platform 4 moves, it drives a connecting block 113 to move. The connecting block 113 drives the belt 112 to move on the pulley assembly 111. The belt 112 drives another connecting block 113 to move in the opposite direction. The other connecting block 113 causes the lower slide plate 5 to slide forward in the fixed base 2. The lower slide plate 5 drives the lifting test platform 7 to move into the frame 1 through the lifting rod assembly 6. When the upper test platform 4 and the lifting test platform 7 move, they will approach each other. The roller 124 slides to the downward recess of the lifting groove 122 on the fixed plate 121. Through the connection between the lifting rod 123 and the lifting test platform 7, the lifting test platform 7 descends from the lower part of the upper test platform 4 as it moves into the frame 1. If the upper testing platform 4 and the lifting testing platform 7 are misaligned, they will be intersected. After the intersecting is completed, the upper testing platform 4 will move out of the frame 1 and slide to the rear of the fixed base 2. The lower slide plate 5 will drive the lifting testing platform 7 into the frame 1. The roller 124 will restore the lifting testing platform 7 to its initial height through the upper part of the lifting groove 122. The backlight keyboard in the positioning fixture 8 on the lifting testing platform 7 will be tested for light effect in accordance with the testing camera 10. At the same time, the staff will continue to put the backlight keyboard to be tested into the positioning fixture 8 on the upper testing platform 4. After the light effect test of the backlight keyboard is completed, the rodless cylinder guide module 3 will control the upper testing platform 4 to move forward, while the lifting testing platform 7 will move backward. When the lifting testing platform 7 and the upper testing platform 4 are close, they will be intersected again. The upper testing platform 4 will drive the backlight keyboard in the positioning fixture 8 to be tested in accordance with the testing camera 10. The lifting testing platform 7 will move to the rear of the fixed base 2 to facilitate the staff to take out the backlight keyboard and put it back in.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
