[0038] The test platform 17 is provided with a guide rail 15, an upper mold bracket is provided on the top of the guide rail 15, the guide rail 15 passes through the platform, and a pull-down cylinder 12 is connected to the bottom of the guide rail 15, and the pull-down cylinder 12 can control the upper mold bracket to move vertically up and down. During the vertical up and down movement of the upper mold bracket, the lower mold bracket moves horizontally in coordination;

[0039] A feeding platform 1 is arranged on the top of the test platform 17, and a third motor is arranged at the bottom of the feeding platform 1. The third motor is used to control the lifting and lowering of the feeding platform 1. A first motor 16 and a second motor 18 are arranged at the bottom of one end of the test platform 17. The first motor 16 is used to control the feeding platform 1 to slide along the transverse guide rail 1701. During the sliding of the feeding platform 1, the upper mold bracket moves vertically up and down.

[0040] It should be noted that synchronization means that the test platform 17 and the unloading platform 1 run synchronously. When the test platform 17 loads materials, the unloading platform 1 receives materials. When the test platform 17 tests, the unloading platform 1 unloads materials. Asynchronism means that the test platform 17 and the unloading platform 1 run independently of each other logically. When the test platform 17 loads materials and tests, the unloading platform 1 is not necessarily receiving materials. The platform can cooperate with the upper and lower motors to perform other tests. A bracket 11 is arranged below the test platform 17. A visual component 19 is arranged on the bracket 11. The visual component 19 includes a horizontal slide, a vertical slide 1904 and a camera 1903. A telecentric lens 1902 is arranged on one side of the camera 1903, and a ring light source 1901 is arranged on one side of the telecentric lens 1902; the upper mold bracket and the lower mold bracket can move in coordination, and the upper mold bracket moves vertically up and down. The outer side of the guide rail 15 located below the test platform 17 is provided with a sleeve, and the sleeve is fixed to the bottom of the test platform 17. The guide rail 15 can slide on the inside of the sleeve. There is a baffle, when the lower mold bracket moves in the horizontal direction, the upper mold bracket can move vertically up and down synchronously or asynchronously; during the synchronous movement, the upper mold bracket 3 moves vertically up and down, and the lower mold bracket moves at the same time, and the moving speed of the upper mold bracket 3 is the same as the moving speed of the lower mold bracket; during the asynchronous movement, the upper mold bracket 3 moves vertically up and down, and the lower mold bracket moves at the same time, and the moving speed of the upper mold bracket 3 is different from the moving speed of the lower mold bracket; a dual-mode testing device, a main body bracket with four upright columns, and a pull-down cylinder 12 sequentially arranged on the lower side of the bracket 11, a closed-loop stepping motor and belt and pulley providing power, a dual-positioning visual system placed on the main X-direction bracket 11, and a dual independent adapter plate module sequentially arranged on the upper side of the bracket 11, a linear slide rail for stabilizing the structural parts, a tank chain 7 for routing, and a position detection photoelectric sensor, wherein the length direction of the test platform 17 is the Y direction, the width direction of the test platform 17 is the X direction, and the vertical direction is the Z direction. The test device is ready for loading. The loading module puts the product into the product cavity of the test device. The motor drives the test device to move to the position below the upper mold. The pull-down cylinder 12 pulls the upper mold down to overlap with the lower mold 4. The adapter plate module begins to align. After the alignment is passed, the product test is carried out. The upper mold suction structure sucks the product. The pull-down cylinder 12 turns off the air, and the product is separated from the lower mold 4. The lower mold 4 of the test device moves to the loading position, the upper mold suction structure cuts off the air source, and the product is placed in the alternating mold cavity. The motor drives the test device to move to the position below the upper mold, and the unloading mechanism takes the product in the alternating mold cavity. This completes the alternating process of product loading, testing, and taking materials. The pull-down cylinder 129 on the lower side of the bracket 11 provides the pressing force for the product to contact the needle mold during testing.

[0041] According to an embodiment of the present invention, a conveyor belt is arranged on one side of the transfer plate mold, a synchronous wheel is arranged on the inner side of the conveyor belt, and the synchronous wheel is cooperatively connected with a stepping motor.

[0042] It should be noted that the closed-loop stepper motor, the conveyor belt and the synchronous wheel device are symmetrically located on both sides of the test platform 17, and are used to provide alternating transmission power and logic for loading, testing and unloading. The first motor is used to provide transmission power and logic for the unloading platform, and the second motor, the conveyor belt and the synchronous wheel are arranged at the rear end of the test device. The second motor is used to provide synchronous or asynchronous transmission power for loading and testing, and the third motor is used to adjust the height of the unloading platform.

[0043] The shape and size of the dual-mode test device can be adjusted according to the size of the product. The dual-mode alternating alignment module structure can greatly improve the efficiency compared to the same action in a single station. The dual-mode alternating alignment structure can be changed to a single mode, which greatly expands the size range of the corresponding products. The alternating action is used to solve the time difference problem. At the same time, it is simple to control, low cost, saves electricity and gas, reduces space, optimizes the combination, and is energy-saving and environmentally friendly.

One end of the sleeve is clamped on the test platform 17. One end of the four guide rails 15 is respectively fixed at the four corners of the flat plate. The four guide rails 15 are driven by the pull-down cylinder 12. The guide rail 15 moves synchronously at the same time to ensure the horizontality of the upper mold and improve the alignment accuracy. In addition, the air pressure of the pull-down cylinder 12 can be controlled by the air pressure regulating valve 9, thereby realizing the descending speed of the guide rail 15 and the slow movement of the guide rail 15. The electromagnetic valve is used to control the movement of the transfer plate mold. The bottom of the transfer plate mold moves with the conveyor belt. In addition, a tank chain 7 is provided on one side of the transfer plate mold. The tank chain 7 is equipped with cables.

It is used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium. The electromagnetic valve can cooperate with different circuits to achieve the expected control, and the accuracy and flexibility of the control can be guaranteed. There are many kinds of electromagnetic valves, and different electromagnetic valves play a role in different positions of the control system. The most commonly used ones are one-way valves, safety valves, directional control valves, speed regulating valves, etc.

[0049] It should be noted that the horizontal slide and the vertical slide 1904 respectively adjust the Z and Y directions of the field of view of the alignment camera 1903 for fine-tuning, which is used to provide precise alignment and manual adjustment between the product and the adapter plate. A groove is provided on the horizontal slide, and the visual component 19 is movably connected in the groove so that the visual component 19 can slide along the groove. During the sliding process of the visual component 19, the shooting position of the camera 1903 can be adjusted. At the same time, the spacing between the two visual components 19 can be adjusted to achieve the coordinated photography of the two visual components 19 with better alignment effect. The vertical slide 1904 can adjust the distance between the camera 1903 and the test platform 17. In addition, the annular light source 1901 on the visual component 19 can supplement the light for the camera 1903 to improve the shooting effect of the camera 1903.

[0050] According to an embodiment of the present invention, the adapter plate is a highly transparent acrylic plate.

[0051] It should be noted that acrylic sheets have excellent transparency, colorless and transparent plexiglass sheets, and a light transmittance of more than 92%.
