Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 The automated testing equipment for packaged electronic products based on robotic arms includes a loading station 1, a first automated loading and unloading mechanism 2, a unloading station 3, and a second automated loading and unloading mechanism 4.

[0021] The loading station 1, the first automatic loading and unloading mechanism 2, the unloading station 3, and the second automatic loading and unloading mechanism 4 are arranged in a row around each other. The loading station 1 is located on one side of the first automatic loading and unloading mechanism 2 and on one side of the second automatic loading and unloading mechanism 4. The unloading station 3 is located on the other side of the first automatic loading and unloading mechanism 2 and on the other side of the second automatic loading and unloading mechanism 4.

[0022] The first automatic loading and unloading mechanism 2 includes a first automatic loading and unloading robot 21 and a first testing unit 22. The first automatic loading and unloading robot 21 is configured to move the packaged electronic products at the loading station 1 to the first testing unit 22 for testing, and to move the packaged electronic products that have passed the test by the first testing unit 22 to the unloading station 3.

[0023] The second automatic loading and unloading mechanism 4 includes a second automatic loading and unloading robot 41 and a second testing unit 42. The second automatic loading and unloading robot 41 is configured to move the packaged electronic products at the loading station 1 to the second testing unit 42 for testing, and to move the packaged electronic products that have passed the test by the second testing unit 42 to the unloading station 3.

[0024] Please see Figure 1 , 2 In some embodiments, the loading station 1 is located at the front right, the first automatic loading and unloading mechanism 2 is located at the front left, the unloading station 3 is located at the rear left, and the second automatic loading and unloading mechanism 4 is located at the rear right.

[0025] In some embodiments, the first testing unit 22 has at least three testing stations (22a, 22b, 22c). All the testing stations (22a, 22b, 22c) of the first testing unit are arranged in an L-shape, with one end of the L-shape pointing to the unloading station 3 and the other end pointing to the loading station 1.

[0026] The product placement positions (such as plate placement positions) of all the test benches (22a, 22b, 22c) of the first test unit correspond to the first automatic loading and unloading robot 21.

[0027] In some embodiments, the second test unit 42 has a plurality of test stations (42a, 42b, 42c) with the same number as the first test unit. All the test stations (42a, 42b, 42c) of the second test unit are arranged in an L-shape, with one end of the L-shape pointing to the unloading station 3 and the other end pointing to the loading station 1.

[0028] The product placement positions (such as plate placement positions) of all the test benches (42a, 42b, 42c) of the second test unit correspond to the second automatic loading and unloading robot 41.

[0029] like Figure 2 As shown, in some embodiments, the loading station 1, all the testing machines (22a, 22b, 22c) of the first testing unit, the unloading station 3, and all the testing machines (42a, 42b, 42c) of the second testing unit are sequentially enclosed to form a virtual quadrilateral.

[0030] In this embodiment, by setting the shape to L, the virtual quadrilateral corresponds to a square or a rectangle.

[0031] In some embodiments, the first automatic loading / unloading robot 21 and the second automatic loading / unloading robot 41 are located in the virtual quadrilateral.

[0032] In some embodiments, the first automatic loading and unloading mechanism 2 further includes a first test NG tray 23, and the first automatic loading and unloading robot 21 is configured to move the packaged electronic products that fail the test of the first test unit 22 to the first test NG tray 23.

[0033] In some embodiments, the first test NG tray 23 is close to the first automatic loading / unloading robot 21 and / or close to the first test unit 22.

[0034] In some embodiments, the second automatic loading and unloading mechanism 4 further includes a second test NG tray 43, and the second automatic loading and unloading robot 41 is configured to move packaged electronic products that fail the test of the second test unit 42 to the second test NG tray 43.

[0035] In some embodiments, the second test NG tray 43 is located near the second automatic loading / unloading robot 41 and / or near the second test unit 42.

[0036] like Figure 1 , 3 As shown, in some embodiments, the first automatic loading and unloading robot 21 and the second automatic loading and unloading robot 41 are both multi-axis robots with multiple degrees of freedom.

[0037] The first automatic loading and unloading robot 21 has a gripping component 24 at its end (or understood as the very end shaft, equivalent to the hand of the robot).

[0038] In some embodiments, the gripping component 24 includes a mounting frame 241 connected to the end of the first automatic loading and unloading robot 21. The mounting frame 241 is provided with a first pneumatic gripper 242 and a second pneumatic gripper 243, which are respectively disposed on both sides of the mounting frame 241 in the horizontal direction.

[0039] The shaft at the end of the first automatic loading and unloading robot 21 has a vertical rotation axis, which enables the mounting frame 241 to rotate so that the first pneumatic gripper 242 and the second pneumatic gripper 243 can switch positions horizontally.

[0040] For example, the first automatic loading and unloading robot 21 first picks up packaged electronic products from the loading station 1 using the first pneumatic gripper 242; then moves them to any test station of the first test unit 22; next, it removes another packaged electronic product that has been tested from the test station using the second pneumatic gripper 243; then, it places the packaged electronic product picked up by the first pneumatic gripper 242 on the product placement position (such as the board placement position) of the test station; finally, the first automatic loading and unloading robot 21 moves the other packaged electronic product that has been tested and picked up by the second pneumatic gripper 243 to the corresponding position: those that pass the test are moved and placed on the unloading station 3, and those that fail the test are moved and placed on the first test NG tray 23.

[0041] During this process, the shaft at the end of the first automatic loading / unloading robot 21 can rotate to switch the positions of the first pneumatic gripper 242 and the second pneumatic gripper 243, so that both the first pneumatic gripper 242 and the second pneumatic gripper 243 can correspond to the product placement position on the testing machine. The shaft at the end of the first automatic loading / unloading robot 21 is driven by a configured drive motor, which is a common setting for robots and will not be described in detail here.

[0042] In some embodiments, the specific arrangement of the second automatic loading and unloading robot 41 can refer to that of the first automatic loading and unloading robot, except that the specific arrangement of the second automatic loading and unloading robot and the first automatic loading and unloading robot are different from those required above.

[0043] In some embodiments, positioning blocks 244 are connected to the clamping fingers of the first pneumatic gripper 242 and the second pneumatic gripper 243. The positioning blocks 244 on the two clamping fingers of the pneumatic gripper (first pneumatic gripper and second pneumatic gripper) are used to clamp and contact the packaged electronic product.

[0044] In some embodiments, the positioning block 244 is a flexible positioning block. When the packaged electronic product is a plate-shaped packaged electronic product such as a circuit board or power board: when the two clamping fingers of the pneumatic gripper approach, the flexible positioning block first contacts the horizontally or nearly horizontally placed plate-shaped packaged electronic product. As it approaches, the plate-shaped packaged electronic product presses against and sinks into the flexible positioning block. The flexible positioning block, through the groove formed by the pressure and indentation of the plate-shaped packaged electronic product, can reverse the action to form a wrapping and positioning effect on the plate-shaped packaged electronic product. On the one hand, it can protect the plate-shaped packaged electronic product from scratches; on the other hand, it can provide a certain degree of positioning effect when clamping and gripping the plate-shaped packaged electronic product.

[0045] In some embodiments, the gripping component 24 further includes a linear drive component 245, which is used to drive the first pneumatic gripper 242 or the second pneumatic gripper 243 to move up and down.

[0046] The linear drive assembly 245 is, for example, a cylinder guide rail assembly, an electric actuator guide rail assembly, or other linear drive assemblies. A first pneumatic gripper or a second pneumatic gripper is mounted on the moving end of the linear drive assembly and is driven by the linear drive assembly to move up and down.

[0047] In some embodiments, the grasping component 24 further includes a camera component 246 mounted on a mounting bracket 241.

[0048] The control system of this automated testing equipment for packaged electronic products can locate the position of the packaged electronic products by using image information (pictures and / or videos) acquired by the camera component, thereby enabling the robotic arm to more accurately grasp the packaged electronic products for automatic loading and unloading.

[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
