[0002] With the continuous development of electronic technology, the waterproof performance of electronic instruments is receiving increasing attention to ensure their performance. This is especially true for products such as smartwatches, mobile phones, home appliances, and automotive electronics, which are frequently exposed to various environmental conditions; waterproof performance has become a crucial criterion for consumers when choosing and using these products. Therefore, conducting scientific and accurate waterproof performance testing is essential to ensure the stable operation of electronic instruments in various environments.

[0003] During the production process of electronic instruments, it is necessary to test their waterproof performance to prevent damage caused by accidental water contact later. Therefore, a waterproof testing device is needed to test the waterproof performance of electronic instruments when they leave the factory.

[0004] Chinese patent document CN222774196U discloses a waterproof testing device for instrument manufacturing, belonging to the field of instrument waterproof testing technology. It includes a testing box, inside which a spray ring is rotatably connected. The outer wall of the spray ring has evenly distributed toothed grooves. A gear is rotatably connected inside the testing box, meshing with the spray ring through the toothed grooves. An adjustment groove is formed on the bottom wall of the spray ring, and an adjustment block for adapting to different instrument models is slidably connected to the bottom wall of the adjustment groove. A flexible plate is fixedly connected to the bottom wall of the adjustment block, and evenly distributed cleaning strips are fixedly connected to the side wall of the flexible plate. A lifting groove is formed on the inner wall of the testing box, and a water depth adjustment component for testing the waterproof performance of instruments at different depths is slidably connected to the inner wall of the testing box through the lifting groove. The flexible plate and cleaning strips allow for simultaneous cleaning of the instrument surface during waterproof testing, improving work efficiency. Simultaneously, the water depth adjustment component enhances the accuracy of the test.

[0005] The existing technology has the following problems: In existing electronic instrument testing devices, continuous loading and unloading of electronic instruments is inconvenient during testing, thus affecting the testing efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide a testing device for electronic instruments to solve the problem of inconvenience in continuously loading and unloading electronic instruments.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a testing device for electronic instruments, comprising a testing box connected to a drive mechanism, and robotic arm mechanisms fixedly mounted on both sides. Each robotic arm mechanism includes a mounting plate fixedly connected to the testing box, a guide groove on the mounting plate, and a lever arm rotatably connected to the mounting plate via the drive mechanism. A sliding rod is slidably connected to the inner wall of a sliding sleeve, and a guide groove is slidably connected to the inner wall of the sliding rod. One end of the guide groove is rotatably connected to a shaft rod three slidably connected to the lever arm and the guide groove, and the other end is fixedly mounted with an electric gripper for clamping the electronic instruments. By rotating the lever arm, the shaft rod three, in cooperation with the guide groove and the lever arm, uses the sliding sleeve as a fulcrum, causing the sliding rod one to swing and extend / retract in the length direction, thereby adjusting the position of the electric gripper and realizing the loading and unloading of the electronic instruments.

[0008] As a preferred embodiment of the present invention, the mounting plate is rotatably connected to a gear three that is fixedly connected to the lever arm, and a rack two is slidably connected to the top of the mounting plate. The rack two meshes with the gear three and is connected to the drive mechanism for transmission. The drive mechanism drives the rack two to move linearly, thereby realizing the rotation of the lever arm.

[0009] As a preferred embodiment of the present invention, a slide rod 2 is rotatably connected to the top of the detection box, and a slide groove 2 is provided in the detection box. One end of the rack 2 is rotatably connected to a shaft 4 that is slidably connected to one end of the slide rod 2. A slider is slidably connected to the other end of the slide rod 2 in the slide groove 2, and the slider is connected to the drive mechanism for transmission. The slider is driven to slide by the drive mechanism, and the movement of the rack 2 is realized by the cooperation between the slide rod 2 and the shaft 4.

[0010] As a preferred embodiment of the present invention, the number of electric grippers and robotic arm mechanisms are both two. Through two sets of robotic arm mechanisms and the gripping of two electric grippers, the electronic instruments can be loaded and unloaded on one side.

[0011] As a preferred embodiment of the present invention, a fixing mechanism is further included. The fixing mechanism includes a mounting plate rotatably connected to the testing box. One side of the mounting plate is rotatably connected to an end face cam fixedly connected to the inner wall of the testing box. A plurality of fixing brackets are fixedly connected to the other side of the mounting plate. An L-shaped rod corresponding to each fixing bracket is movably sleeved in the middle of the mounting plate. One end of the L-shaped rod is fixedly connected to a pressure plate that cooperates with the fixing bracket. The other end of the L-shaped rod is fixedly connected to a spring connected to the mounting plate. The spring pulls the L-shaped rod, causing the pressure plate to move away from the fixing bracket, which facilitates the placement of electronic instruments between the pressure plate and the fixing bracket.

[0012] As a preferred embodiment of the present invention, the other end of the L-shaped rod is rotatably connected to a roller that cooperates with the end face cam. The mounting plate drives the L-shaped rod to rotate. By cooperating with the end face cam and the roller, the L-shaped rod is pushed to move through the end face cam, so that the pressure plate moves toward the fixed bracket. The pressure plate and the fixed bracket are used to clamp and fix the electronic instrument.

[0013] In a preferred embodiment of the present invention, a support base is fixedly connected to the bottom of the testing box; the driving mechanism includes a motor fixedly connected to the support base; a crankshaft is fixedly connected to the output end of the motor; a fixed disk is fixedly connected to one side of the testing box; a second mounting disk, which is rotatably connected to the testing box and driven by the first mounting disk, is rotatably connected to one side of the second mounting disk; several shafts (first and second) are fixedly connected to one side of the second mounting disk, arranged in a circumferential array and spaced apart; a rotating shaft is rotatably connected to the top of the fixed disk; the fixed disk... A fork plate that slidably connects to shaft two is provided. The crankshaft is rotatably connected to a double-headed fork plate that mates with shaft one. The top of the double-headed fork plate is slidably connected to the rotating shaft. The double-headed fork plate is rotatably connected to a connecting rod that is rotatably connected to the fork plate. The crankshaft drives the double-headed fork plate to swing back and forth, so that the double-headed fork plate, guided by the rotating shaft, engages with shaft one. The swinging of the double-headed fork plate drives the mounting plate two to produce intermittent indexing rotation. When the double-headed fork plate separates from shaft one, the fork plate engages with shaft two, thereby fixing the rotating mounting plate two.

[0014] As a preferred embodiment of the present invention, the top of the detection box is rotatably connected to a drive disk that is slidably connected to two sliders. By rotating the drive disk, the two sliders are driven to move synchronously.

[0015] As a preferred embodiment of the present invention, gear one and gear two are fixedly connected to both ends of the rotating shaft, rack one meshing with gear two is fixedly connected to the double-headed fork plate, and gear disk meshing with gear one is fixedly connected to the drive disk. The rack one is driven to move back and forth by the double-headed fork plate, and gear two is driven to rotate by rack one, thereby driving the drive disk to rotate back and forth by gear one.

[0016] As a preferred embodiment of the present invention, a water spray system is fixedly connected to both sides of the test box, a filter screen is fixedly connected to the bottom of the inner cavity of the test box, and the input end of the water spray system is connected to the bottom of the inner cavity of the test box for water spray testing of electronic instruments.

[0017] The present invention has the following beneficial effects: 1.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0025] Please see Figures 1-3 As shown, this invention is a testing device for electronic instruments, including a testing box 1. The testing box 1 is connected to a driving mechanism 5. Mechanical arm mechanisms 6 are fixedly installed on both sides of the testing box 1. A water spray system 8 is fixedly connected to both sides of the testing box 1. A filter screen 3 is fixedly connected to the bottom of the inner cavity of the testing box 1. The input end of the water spray system 8 is connected to the bottom of the inner cavity of the testing box 1 for water spray testing of electronic instruments 2. Specifically, when conducting waterproof testing of electronic instruments 2, a certain amount of water is injected into the inner cavity of the testing box 1. The water level must not be higher than the output end of the water spray system 8, nor lower than the top of the electronic instruments 2 located at the bottom, so as to conduct rain and immersion tests on electronic instruments 2 to achieve the purpose of waterproof testing.

[0026] Please see Figure 2 and Figures 5-8As shown, the robotic arm mechanism 6 includes a mounting plate 61 fixedly connected to the detection box 1. The mounting plate 61 has a guide groove 62. The mounting plate 61 is rotatably connected to a lever arm 63 that is driven by a drive mechanism 5. The mounting plate 61 is also rotatably connected to a sliding sleeve 66. A sliding rod 65 is slidably connected to the inner wall of the sliding sleeve 66. One end of the sliding rod 65 is rotatably connected to a shaft 64 that is slidably connected to the lever arm 63 and the guide groove 62. The other end is fixedly mounted with an electric gripper 9 for clamping the electronic instrument 2. By rotating the lever arm 63, the shaft 64, in cooperation with the guide groove 62 and the lever arm 63, uses the sliding sleeve 66 as a fulcrum, causing the sliding rod 65 to swing and extend in the length direction, thereby adjusting the position of the electric gripper 9 and realizing the loading and unloading of the electronic instrument 2.

[0027] Mounting plate 61 is rotatably connected to gear 3 68 which is fixedly connected to lever arm 63, and rack 2 67 is slidably connected to the top. Rack 2 67 meshes with gear 3 68 and is connected to drive mechanism 5. Drive mechanism 5 drives rack 2 67 to move linearly, thereby rotating lever arm 63.

[0028] The top of the testing box 1 is rotatably connected to a slide rod 612. The testing box 1 has a slide groove 611. One end of a rack 67 is rotatably connected to a shaft 69 that is slidably connected to one end of the slide rod 612. A slider 613 is slidably connected to the other end of the slide rod 612 via the slide groove 611. The slider 613 is connected to a drive mechanism 5, which drives the slider 613 to slide. The movement of the rack 67 is achieved through the cooperation between the slide rod 612 and the shaft 69. Specifically… The top of the detection box 1 is provided with a through groove 1 that is slidably connected to the shaft 69, so that the shaft 69 passes through the detection box 1 to connect the rack 67 and the slide bar 612. Both ends of the slide bar 612 are provided with through grooves 2 that are slidably connected to the shaft 69 and the slider 613, respectively, so that the shaft 69 and the slider 613 slide on the slide groove 1 610 and the slide groove 2 611, respectively, while the shaft 69 and the slider 613 slide on the through groove 2 on the rotating slide bar 612.

[0029] There are two electric grippers 9 and two robotic arm mechanisms 6. By using two sets of robotic arm mechanisms 6 and the gripping of two electric grippers 9, the electronic instrument 2 can be loaded and unloaded on one side.

[0030] Included in the instruction manual Figure 2For example, the two electric grippers 9 are symmetrically arranged, and the rotation angle of the electric grippers 9 about the sliding sleeve 66 is 135°. When the shaft 64 is located at both ends of the guide groove 62, the electric grippers 9 will not rotate, but will move in a straight line to pick up and put down the electronic instrument 2. The lever arm 63 is provided with a sliding groove so that by rotating the lever arm 63, the shaft 64 can slide on the inner wall of the guide groove 62, thereby driving the shaft 64.

[0031] Please see Figures 1-4 , Figure 9 and Figure 10 As shown, it also includes a fixing mechanism 4, which includes a mounting plate 41 rotatably connected to the detection box 1. One side of the mounting plate 41 is rotatably connected to an end face cam 42 fixedly connected to the inner wall of the detection box 1. The other side of the mounting plate 41 is fixedly connected to several fixing brackets 43. An L-shaped rod 45 corresponding to each fixing bracket 43 is movably sleeved in the middle of the mounting plate 41. One end of the L-shaped rod 45 is fixedly connected to a pressure plate 44 that cooperates with the fixing bracket 43. The other end of the L-shaped rod 45 is fixedly connected to a spring 46 connected to the mounting plate 41. The spring 46 pulls the L-shaped rod 45, causing the pressure plate 44 to move away from the fixing bracket 43, so that the electronic instrument can be placed between the pressure plate 44 and the fixing bracket 43.

[0032] The other end of the L-shaped rod 45 is rotatably connected to a roller 47 that cooperates with the end face cam 42. The mounting plate 41 drives the L-shaped rod 45 to rotate. By cooperating with the end face cam 42 and the roller 47, the end face cam 42 pushes the L-shaped rod 45 to move, so that the pressure plate 44 moves toward the fixed bracket 43. The pressure plate 44 and the fixed bracket 43 are used to clamp and fix the electronic instrument.

[0033] Included in the instruction manual Figure 4 and Figure 9 For example, by rotating the mounting plate 41, when the fixing bracket 43 rotates to the position of the top groove, the L-shaped rod 45 is pushed forward under the action of the spring 46, so that the fixing bracket 43 and the pressure plate 44 are separated. Then, the electronic instrument 2 can be placed between the fixing bracket 43 and the pressure plate 44 using the electric gripper 9. Then, by rotating the mounting plate 41, the protruding part of the end face cam 42 pushes the L-shaped rod 45 backward, so that the fixing bracket 43 and the pressure plate 44 can fix the electronic instrument 2. Then, the instrument 2 is tested for waterproofness. After the test, when the electronic instrument 2 rotates from the position of the protruding end face cam 42 to the recessed position on the other end, the fixing bracket 43 and the pressure plate 44 are separated under the action of the spring 46. Then, the electronic instrument 2 after the waterproof test can be removed using another electric gripper 9, so as to perform continuous waterproof testing on the electronic instrument 2.

[0034] Please seeFigures 1-3 and Figures 5-8 As shown, a support base 7 is fixedly connected to the bottom of the testing box 1. The drive mechanism 5 includes a motor 51 fixedly connected to the support base 7. A crankshaft 52 is fixedly connected to the output end of the motor 51. A fixed plate 55 is fixedly connected to one side of the testing box 1. A second mounting plate 56, which is rotatably connected to the first mounting plate 41, is driven by the testing box 1. Several shafts 53 and 54 are fixedly connected to one side of the second mounting plate 56. The shafts 53 and 54 are arranged in a circumferential array and are spaced apart. A rotating shaft 511 is rotatably connected to the top of the fixed plate 55. A shaft 54 ​​is slidably connected to the fixed plate 55. The fork plate 57 is connected to the crankshaft 52, and a double-headed fork plate 59 is rotatably connected to the shaft 53. The top of the double-headed fork plate 59 is slidably connected to the rotating shaft 511. The double-headed fork plate 59 is rotatably connected to the connecting rod 58, which is rotatably connected to the fork plate 57. The crankshaft 52 drives the double-headed fork plate 59 to swing back and forth, so that the double-headed fork plate 59 is inserted into the shaft 53 under the guidance of the rotating shaft 511. The swing of the double-headed fork plate 59 drives the second mounting plate 56 to produce intermittent indexing rotation. When the double-headed fork plate 59 is separated from the shaft 53, the fork plate 57 is inserted into the shaft 54 ​​to fix the rotating mounting plate 56.

[0035] The rotation of crankshaft 52 by motor 51 drives double-headed fork plate 59 to rotate around the crankshaft on crankshaft 52. The double-headed fork plate 59 is guided by rotating shaft 511, causing it to move up and down. When the bottom of double-headed fork plate 59 reaches the bottom position, the top of fork plate 57 releases its fork connection to shaft 2 54, while the bottom of double-headed fork plate 59 forks onto the outer wall of shaft 1 53, causing mounting plate 2 56 to rotate at a rotation angle of 45°. Then, double-headed fork plate 59 moves upward, releasing the fork connection between double-headed fork plate 59 and shaft 1 53. At the same time, connecting rod 58 drives fork plate 57 to move upward, causing fork plate 57 to fork onto shaft 2 54, fixing mounting plate 2 56, and realizing the intermittent rotation of mounting plate 2 56 driving mounting plate 1 41.

[0036] The top of the detection box 1 is rotatably connected to a drive disk 515 that is slidably connected to two sliders 613. The drive disk 515 has two arc-shaped through slots to move the two sliders 613. By rotating the drive disk 515, the two sliders 613 are driven to move synchronously.

[0037] Gear 1 510 and gear 2 512 are fixedly connected to both ends of the rotating shaft 511, respectively. A rack 1 513 that meshes with gear 2 512 is fixedly connected to the double-headed fork plate 59. A gear disk 514 that meshes with gear 1 510 is fixedly connected to the drive disk 515. The rack 1 513 is driven to move back and forth through the double-headed fork plate 59. The rack 1 513 drives gear 2 512 to rotate, thereby driving the drive disk 515 to rotate back and forth through gear 1 510.

[0038] The up-and-down movement of the double-headed fork plate 59 causes the rack 513 to drive the meshing gears 512 and 510 to rotate, thereby driving the meshing gear disk 514 to rotate, causing the drive disk 515 to reciprocate, and causing the two sliders 613 to reciprocate on the slide groove 611, thus realizing the control of the electric gripper 9.
