[0029] The present invention will be further described in detail below with reference to specific embodiments.

[0030] Example:

[0031] like Figure 1 and Figure 2 As shown, a dual-station automatic electrical testing device 100 of this utility model includes a frame 1, a first transfer component 2a, a second transfer component 2b, an electrical testing component 3, and two industrial cameras 4. The first transfer component 2a and the second transfer component 2b have the same structure and are arranged in parallel in the middle of the frame 1. The electrical testing component 3 stands above the first transfer component 2a and the second transfer component 2b. The two industrial cameras 4 are both located on the upper part of the frame 1 and respectively take pictures of the first transfer component 2a or the second transfer component 2b.

[0032] The frame 1 serves as the fixed foundation for the entire equipment. The first transfer assembly 2a and the second transfer assembly 2b constitute two workstations. Each workstation can independently move multiple electronic products 200 together to the underside of the electrical testing assembly 3 for inspection. An industrial camera 4 is used for positioning the electronic products 200, enabling the electrical testing assembly 3 to accurately locate each product 200 and complete its inspection sequentially. With alternating loading at the two workstations, the electrical testing assembly 3 automatically inspects multiple electronic products 200 at one workstation while simultaneously replacing them at the other workstation, significantly improving electrical testing efficiency.

[0033] like Figure 1 As shown, the frame 1 includes a central platform 11, four casters 12 at the bottom, a display screen 13 at the top, optical gratings 14 on both sides, and a storage space 15 below the platform 11. A workspace is formed inside the frame 1 and above the platform 11. The first transfer assembly 2a, the second transfer assembly 2b, the electrical measurement assembly 3, and two industrial cameras 4 are all located within this workspace. The optical gratings 14 are located on both sides of the open opening of the workspace. The first transfer assembly 2a, the second transfer assembly 2b, and the electrical measurement assembly 3 are all mounted on the platform 11.

[0034] The casters 12 are used to move the entire dual-station automatic electrical testing equipment 100. The display screen 13 is used to display the test results of the electrical testing component 3, thereby guiding the operator to eliminate defective products. Because the first transfer component 2a, the second transfer component 2b, and the electrical testing component 3 all include many moving parts, and the industrial camera 4 cannot have its lens blocked by foreign objects, the grating 14 needs to detect whether foreign objects have entered the workspace during equipment operation to avoid accidents. Once the grating 14 detects a foreign object, the equipment needs to be stopped immediately. The storage space 15 is used to place items needed during operation for easy access.

[0035] like Figure 3 As shown, both the first transfer assembly 2a and the second transfer assembly 2b include an X-axis module 21 and a carrier plate 22 driven by the X-axis module 21 to move along the X-axis. The carrier plate 22 positions multiple electronic products 200. Multiple X-axis sensors 211 are provided on the side of the X-axis module 21, and a first sensing plate 221 that cooperates with the X-axis sensors 211 is connected to the lower part of the carrier plate 22. The X-axis is located in the horizontal plane.

[0036] The X-axis module 21 is fixed on the machine base 11, thereby driving the carrier plate 22 in and out of the working space. When the carrier plate 22 is outside the working space, it is in the operator's operating position, at which time material changing can be performed; when the carrier plate 22 is inside the working space, it is in the detection position below the electrical testing component 3, at which time the electrical testing component 3 will automatically complete the electrical test. When the carrier plate 22 is in the operating position or the detection position, the first sensing element 221 will correspond to the position of an X-axis sensor 211, thus determining the position of the carrier plate 22 and also helping the electrical testing process determine the initial position of the carrier plate 22.

[0037] like Figure 4 and Figure 5 As shown, the electrical testing assembly 3 includes a gantry 31 spanning above the first transfer assembly 2a and the second transfer assembly 2b, a Y-axis module 32 located on the upper part of the gantry 31, a lifting mechanism 33 driven by the Y-axis module 32 to move along the Y-axis, a probe fixing plate 34 driven by the lifting mechanism 33 to move along the Z-axis, and a plurality of probes 35 disposed on the probe fixing plate 34. The lifting mechanism 33 includes a vertical plate 331 directly driven by the Y-axis module 32, a second sensing plate 332 disposed on the back of the vertical plate 331, a drive motor 333 disposed on the vertical plate 331, two pulleys 334 rotatably connected to the front of the vertical plate 331, and a belt 335 wound around the two pulleys 334. The two pulleys 334 are in an upper-lower relationship and their axes are both along the X-axis. The drive motor 333 drives the upper pulley 334, and the back of the probe fixing plate 34 is fixed to a point on the belt 335. The front of the upright plate 331 is provided with a Z-axis slide rail 336, and the back of the probe fixing plate 34 is provided with a Z-axis slider 337 that cooperates with the Z-axis slide rail 336. The Y-axis is located in the horizontal plane and is perpendicular to the X-axis, while the Z-axis is vertical. A number of Y-axis sensors 321 that cooperate with the second sensing plate 332 are provided on one side of the Y-axis module 32.

[0038] The probe 35 performs electrical detection by contacting the upper surface of the electronic product 200. The probe 35 needs three degrees of freedom (X, Y, and Z) relative to the electronic product 200. Because the carrier plate 22 on which the electronic product 200 is located can move along the X direction, the probe 35 needs two degrees of freedom (Y and Z). The Z-axis slide rail 336, in cooperation with the Z-axis slider 337, ensures that the probe fixing plate 34 can only move vertically. The combination of the drive motor 333, pulley 334, and belt 335 is one driving method; alternatively, a linear drive mechanism such as a slide cylinder or a screw-sleeve mechanism can be used. The Y-axis sensor 321 positions the vertical plate 331 in the Y direction via the second sensing element 332, allowing the probe 35 to accurately adapt to the detection positions at the two workstations.

[0039] The working process of the dual-station automatic electrical testing equipment 100 is as follows:

[0040] The carrier plate 22 of the first transfer assembly 2a is moved outside the workspace by the X-axis module 21. When the first sensing plate 221 is sensed by the X-axis sensor 211 located on the outside, the X-axis module 21 stops operating, and the operator positions the arrayed electronic products 200 on the carrier plate 22. The X-axis module 21 moves the carrier plate 22 below the gantry 31. When the X-axis sensor 211 on the inside senses the first sensing plate 221, the carrier plate 22 stops moving. At this time, both the carrier plate 22 and the probe 35 are within the field of view of the industrial camera 4. Under the monitoring of the industrial camera 4, the probe 35 is adjusted in the Y-axis position, and the carrier plate 22 is adjusted in the X-axis position, so that the probe 35 is above the electronic product 200 to be inspected. Then, the lifting mechanism 33 moves the probe 35 down to contact the electronic product 200, thereby connecting the detection circuit at the first workstation. The device automatically adjusts the relative position of the probe 35 and the carrier plate 22 to connect the next electronic product 200, thus completing the second inspection. This process continues until all electronic products 200 on the carrier plate 22 have been inspected, at which point the carrier plate 22 is sent out of the workspace. During the interval between inspections at the first station, the carrier plate 22 of the second transfer assembly 2a is moved outside the workspace, and the loading and alignment at the second station are completed in the same manner. Once all electronic products 200 at the first station have completed their electrical tests, the probe fixing plate 34 can immediately move to the second station and, guided by another industrial camera 4, complete the electrical tests of all electronic products 200 at the second station. The first and second stations are inspected alternately.

[0041] This invention enables the batch delivery of electronic products 200 to the testing station using a carrier plate 22. The probe 35 then automatically adapts to the position of each electronic product 200, continuously completing the testing of a large number of products. During the testing process, workers can change materials at another station. The equipment is compact and has a fast testing pace. Experience shows that the testing efficiency can be increased from 240 psc / H to 800 ps / H.

[0042] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
