[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0035] like Figure 1 and Figure 2 As shown, the power consumption current testing device of the embodiment of the utility model includes a base 1, a limit fixture 2, a guide column 3, a probe plate 4, a first driver 10, a power connection module 5 and a second driver.

[0036] The base 1 can be a rectangular parallelepiped as a whole and has a hollow structure. For example, the base 1 can be formed by welding steel plates. The limiting fixture 2 is provided on the base 1, and the limiting fixture 2 is provided with a limiting groove 21 for placing the product to be inspected. Figure 1 and Figure 2 As shown, the limiting clamp 2 can be fixed on the top surface of the base 1, and the fixing method can be welding, clamping, fastener fixing, etc.

[0037] The limiting fixture 2 can be a plate-like structure as a whole, and the limiting groove 21 can be provided on the top side of the limiting fixture 2 and can be a rectangular groove, and the notch of the limiting groove 21 can be arranged upward. The product to be inspected can be a motherboard of an electronic product such as a mobile phone or a tablet computer, etc. During the inspection, the product to be inspected can be directly placed in the limiting groove 21, and the mutual blocking between the groove wall of the limiting groove 21 and the peripheral wall of the product to be inspected can also play the effect of positioning and restraining the product to be inspected, thereby facilitating the precise plugging of the product to be inspected with the subsequent power connection module 5.

[0038] The guide column 3 is arranged on the base 1 and extends along the depth direction of the limit groove 21. The probe plate 4 and the limit clamp 2 are located on the same side of the base 1. The probe plate 4 is slidably assembled on the guide column 3, and the probe plate 4 is provided with a plurality of probes for electrically contacting the test points of the product to be inspected.

[0039] For example, Figure 1 and Figure 2 As shown, the guide column 3 can be a cylindrical structure, which can be fixed on the top side of the base 1 and can extend in the up and down directions. There can be multiple guide columns 3, and the multiple guide columns 3 can be arranged in a straight line and arranged in parallel and spaced apart in the left and right directions.

[0040] The probe plate 4 is located on the top side of the base 1 and can be arranged horizontally, and in the up and down direction, the probe plate 4 can be arranged opposite to the limit groove 21. The probe plate 4 can be directly slidably assembled with each guide column 3. For example, a guide hole can be provided on the probe plate 4, and the guide column 3 can be matched in the corresponding guide hole. A plurality of probes can be provided on the probe plate 4. The material of the probe plate 4 can be plastic, acrylic plate, etc. The plurality of probes can be fixed in the probe plate 4 by injection molding, etc., and the bottom ends of the plurality of probes can extend from the bottom side of the probe plate 4.

[0041] When in use, the probe plate 4 can slide up and down along the guide column 3. When the probe plate 4 moves downward, the multiple probes on the probe plate 4 can press and contact with the multiple test points of the product to be tested placed in the limit groove 21 and achieve electrical connection, thereby achieving the use needs of power consumption current detection. When the probe plate 4 moves upward, the multiple probes on the probe plate 4 can be separated from the multiple test points of the product to be tested.

[0042] It should be noted that the power consumption current test items may include a charge current test, a power on current test by cai mode, a deep sleep current test, a power off current test, and the like.

[0043] The first driver 10 is disposed on the base 1, and the first driver 10 is used to drive the probe card 4 to slide along the guide column 3 so that the multiple probes of the probe card 4 can stop at the multiple probes respectively. Figure 2 As shown, the first driver 10 can be arranged in the base 1, and the first driver 10 can be a linear drive such as a cylinder, an electric push rod, etc. The top end of the first driver 10 can extend from the top wall of the base 1 and be connected to the probe plate 4. When in use, the up and down movement of the driving end of the first driver 10 can drive the probe plate 4 to move up and down, so that the point contact and separation of the probe and the test point can be achieved.

[0044] The power connection module 5 is arranged on the second driver and is used to be electrically connected to the test system. The second driver is arranged on the base 1 and is used to drive the power connection module 5 to move so that the power connection module 5 can be plugged and matched with the set interface of the product to be tested.

[0045] For example, the second driver can be mounted on the base 1 by fasteners, and the second driver can also be a linear drive such as a cylinder or an electric push rod. The test system can include equipment such as a test host, in which corresponding test software is pre-installed, and the test host can be electrically connected to the power connection module 5 through a wire. The power connection module 5 is fixed to the driving end of the second driver, and the power connection module 5 can be located at the front side of the limit clamp 2.

[0046] When testing is required, the driving end of the second driver can reciprocate in the front-to-back direction. When the driving end moves backward, the power connection module 5 can be displaced backward. At this time, the power connection module 5 can be plugged and assembled with the setting interface of the product to be tested placed in the limit groove 21, so that the electrical connection between the product to be tested and the test system can be achieved, meeting the use needs of the transmission of current and other data. The setting interface can be a USB interface, a type-c interface, etc. When the product to be tested is a mobile phone motherboard, the setting interface can specifically be a tail interface on the mobile phone.

[0047] In the power consumption current testing device of the embodiment of the utility model, the connection between the test system and the product to be tested can be achieved by driving the power connection module 5 to move by the second driver to achieve plug-in assembly. Due to the limiting effect of the limiting groove 21, the stability of the linear drive of the second driver, etc., the accurate plug-in between the setting interface of the product to be tested and the power connection module 5 is guaranteed, and the plug-in deviation caused by jitter, field of view deviation, etc. during manual operation is avoided, and the damage to the setting interface during the plug-in process is avoided, thereby reducing the defective rate of the product and improving the overall production efficiency compared to manual operation.

[0048] In some embodiments, the limiting clamp 2 is provided with an opening, which is provided on the side of the limiting clamp 2 facing the power connection module 5, the opening is connected to the limiting groove 21, and when the power connection module 5 is plugged into the setting interface, at least part of the power connection module 5 fits in the opening.

[0049] For example, Figure 1 As shown, the opening can be provided at the front side of the limiting fixture 2, and the opening can be a rectangular opening, and the overall size of the opening can be slightly larger than the size of the power connection module 5. When the second driver drives the power connection module 5 to move backward and plug it into the product to be inspected, the power connection module 5 can be embedded in the opening, and the accurate plugging of the power connection module 5 and the product to be inspected can be further ensured by the limiting of the opening, thereby improving the overall stability of the operation.

[0050] In some embodiments, the power connection module 5 includes a fixed block 51 and an adapter 52, the fixed block 51 is connected to the second driver, the adapter 52 is arranged on the fixed block 51, and the adapter 52 has a first interface and a second interface, the first interface is used to plug and cooperate with the set interface, and the second interface is used to connect to the test system through a wire.

[0051] For example, Figure 1 and Figure 2 As shown, the fixing block 51 may be in a rectangular shape, and the material of the fixing block 51 may be plastic, etc. The fixing block 51 may be fixed to the top of the second driver by a fastener. The top side of the fixing block 51 may be provided with an assembly groove, which may extend along the front-to-back direction and penetrate the fixing block 51, and the adapter 52 may be embedded in the assembly groove.

[0052] The adapter 52 can be a type-c adapter, and an interface is provided at both the front and rear ends of the adapter 52. The interface located on the front side can be a second interface, and the second interface can be connected to the test system via a data cable (wire). The interface located on the rear side can be a first interface, and the first interface can be plugged in and matched with the set interface of the product to be tested.

[0053] In some embodiments, the base 1 is provided with an inner cavity, and the limiting fixture 2, the guide column 3, and the probe plate 4 are all located on the top side of the base 1. Figure 1As shown, the top side of the base 1 is provided with an opening, and the power connection module 5 fits in the opening and can reciprocate in the opening along the front-back direction. The first driver 10 and the second driver are both arranged in the inner cavity of the base 1.

[0054] Therefore, on the one hand, it is convenient to place the product to be inspected in the limit groove 21 from top to bottom, which conforms to the ergonomic design and improves the convenience of manual operation. On the other hand, the first driver 10 and the second driver can be hidden in the base 1, thereby protecting the driving components.

[0055] In some embodiments, Figure 1 and Figure 2 As shown, the power consumption current test device includes a door frame 7 and a sliding plate 6. The door frame 7 is in the shape of a door as a whole. The door frame 7 is arranged on the top side of the base 1. There are multiple guide columns 3, and the multiple guide columns 3 are connected between the top beam of the door frame 7 and the base 1. The material of the guide column 3 and the sliding plate 6 can be metal. The sliding plate 6 is slidably assembled on the multiple guide columns 3. For example, the sliding plate 6 can be provided with multiple guide holes. The multiple guide columns 3 are slidably matched in the multiple guide holes one by one. The probe plate 4 is fixed below the sliding plate 6, thereby realizing the indirect sliding assembly of the probe plate 4 and the guide column 3.

[0056] The setting of the sliding plate 6 avoids the need to arrange guide holes on the probe plate 4, thereby avoiding the situation where the probes are easily touched during the processing of the guide holes and causing probe failure, and avoids the problem that the probe plate 4 is easily damaged during secondary processing.

[0057] Optionally, a sliding sleeve may be installed in each guide hole of the sliding plate 6 . The material of the sliding sleeve may be copper or the like. The sliding plate 6 may be slidingly assembled with the guide column 3 via the sliding sleeve.

[0058] In some embodiments, the gantry 7, the sliding plate 6, the probe plate 4, the limit clamp 2, the guide column 3, the power connection module 5, the first driver 10, and the second driver form a test unit. There are multiple test units, and the multiple test units are all arranged on the base 1.

[0059] For example, Figure 1 and Figure 2 As shown, four test units can be provided, the base 1 can be rectangular and can extend along the left-right direction, and the four test units can be arranged at intervals along the length direction (left-right direction) of the base 1, thereby meeting the needs of testing multiple products to be inspected at the same time and improving the overall test efficiency.

[0060] In some other embodiments, the number of the test units may be three, five, six, etc.

[0061] In some embodiments, the base 1 is provided with a plurality of control switches 9, the plurality of control switches 9 correspond to the plurality of test units one by one, and each control switch 9 is used to control the opening and closing of the corresponding test unit. Figure 1 As shown, consistent with the number of the above-mentioned test units, the number of control switches 9 can also be four, and the four control switches 9 can all be arranged on the top side of the base 1, and each control switch 9 can be located on the left side of the corresponding test unit. During testing, the corresponding test unit can be started or shut down by pressing the corresponding control switch 9, thereby realizing the independence of the control of each test unit.

[0062] In some embodiments, the first driver 10 and the second driver are both pneumatic drivers. For example, the first driver 10 and the second driver can both be cylinders, etc. The pneumatic driver has a fast switching rate and can fully meet the needs of production capacity.

[0063] In some embodiments, the sliding plate 6 is provided with an avoidance hole 61, and the connection lines of the plurality of probes are all fitted in the avoidance hole 61. Figure 1 As shown, the sliding plate 6 as a whole can be a square frame structure, the avoidance hole 61 is the space area surrounded by the sliding plate 6, and the avoidance hole 61 as a whole can be a rectangular square hole, and the connection lines of multiple probes can extend outward through the avoidance hole 61.

[0064] In some embodiments, the probe board 4 is provided with at least one stop member 8, which is elastic and when multiple probes of the probe board 4 are in abutment contact with multiple test points, the stop member 8 presses against the product to be inspected to avoid partial warping of the product to be inspected.

[0065] For example, Figure 1 As shown, two stop members 8 can be provided on the front side of each probe board 4. Since the multiple probes on the probe board 4 are mostly distributed in the rear half of the probe board 4, when the multiple probes stop at multiple test points of the product to be inspected, the front half of the product to be inspected is prone to warping upward due to the lack of limit. The setting of the stop members 8 can play a role in pressing the probe board 4 downward, thereby avoiding the problem of the front half of the probe board 4 warping up, ensuring the horizontality of the probe board 4, and thus avoiding the situation where the probes cannot contact the corresponding test points well due to the tilt of the probe board 4, ensuring good contact, and then ensuring the accuracy and stability of the test.

[0066] The material of the stop member 8 can be rubber, silicone or other materials with a certain degree of elasticity. Since the stop member 8 needs to be directly stopped on the probe plate 4, the elastic material can reduce damage to the product to be inspected and play a protective effect.

[0067] In some embodiments, the power consumption current testing device includes a sensor, which is disposed on the wall of the limiting groove 21 and is used to sense the product to be tested. Figure 1 As shown, the sensor can be a photosensitive, electromagnetic, contact type, etc. Taking the electromagnetic type as an example, a Hall sensor can be embedded on the bottom wall of the limit groove 21, and a magnet can be fixed on the product to be inspected. When the product to be inspected is placed in the limit groove 21, the Hall sensor can generate an electromagnetic signal (induction signal), thereby realizing the monitoring of the taking and placing of the product to be inspected.

[0068] In some embodiments, when the sensor detects that the product to be inspected is placed in the limit slot 21, the sensing signal can be transmitted to the corresponding control device, and the control device can automatically turn on the above-mentioned control switch 9, thereby driving the first driver 10 and the second driver to operate and complete the detection operation by itself, thereby realizing the automation of the detection.

[0069] In other embodiments, the sensor can also play a role in correcting the position. For example, when the product to be inspected is deflected in the limit groove 21, the sensor will not generate a sensing signal because it is not aligned with the corresponding part on the product to be inspected. At this time, manual correction of the product to be inspected is required before the inspection operation can be performed, thereby ensuring the precise docking of the product to be inspected and the power connection module 5.

[0070] In some embodiments, the probe plate 4 may be a transparent plate, and the material of the probe plate 4 may be an acrylic plate, etc., so that the operator can observe the condition of the product to be inspected below through the probe plate 4 .

[0071] The power consumption current testing device of the embodiment of the utility model replaces the employee's operating actions. Through the actions of the first driver 10 and the second driver, the docking of the product USB interface and the automatic downward pressing of the probe plate 4 can be realized. The employee then puts the product to be tested into the limit clamp 2 and presses the start button, and the clamp can automatically perform the action test instead of manual work, which reduces the waste of manual testing actions by personnel and also eliminates the phenomenon of damage to the product USB interface.

[0072] Secondly, through the automatic power consumption current testing device, the test items are combined to achieve unified standardization, avoiding problems such as unstable production capacity due to employee fatigue, low product yield, and low production efficiency. According to preliminary statistical comparisons, the power consumption current testing device of the embodiment of the utility model can control the product defective rate within 0.1%, reduce production costs, and fully meet the needs of using efficient production capacity.
