[0040] The terms "first" and "second" in this utility model are used for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as a restriction on the order of events.

[0041] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0042] In existing demolding fixtures, after fixing the electronic device to the fixing block, it is generally necessary to manually pull the lever to push the test board closer to the electronic device so that the plug on the test board can connect with the socket of the electronic device, which is inefficient.

[0043] The following is a preferred embodiment of a testing device provided by this utility model that can solve the above-mentioned technical problems.

[0044] A preferred embodiment of this utility model provides a testing device, which includes a substrate and a demolding pneumatic clamp.

[0045] Please refer to Figure 1 A pneumatic demolding fixture is used to test electronic device 100, comprising a support frame 1, a test plate 2, and a double-rod cylinder 3. The support frame 1 is fixed to the substrate. The support frame 1 includes a first rod 11 and two second rods 12. The first rod 11 extends laterally ( Figure 1 The test plate 2 extends in the x-direction. Two second rods 12 are perpendicularly connected to the first rod 11. The two second rods 12 extend in the same direction and are spaced laterally. The two second rods 12 are used to clamp the electronic device 100. The two second rods 12 and the first rod 11 form a receiving space 13. The test plate 2 extends laterally and longitudinally (in the x-direction). Figure 1The test plate 2 (located in the y-direction) is positioned within the accommodating space 13. Two plugs 21 are located on the side of the test plate 2 facing away from the first rod 11, arranged laterally for mating with the sockets of the electronic device 100. The cylinder body of the double-rod cylinder 3 is connected to the support frame 1. The two piston rods of the double-rod cylinder 3 are arranged laterally and connected to the test plate 2, driving the test plate 2 to move longitudinally so that the two plugs 21 respectively mate with the two sockets of the electronic device 100.

[0046] This utility model discloses a pneumatic demolding fixture and testing device. After fixing the electronic device 100 between two second rods 12, a double-rod cylinder 3 automatically drives the test plate 2 close to the electronic device 100 to connect the two plugs 21 to the two sockets of the electronic device 100, effectively improving efficiency and reducing the workload of operators. In addition, the test plate 2 has two plugs 21 arranged in the horizontal direction, so the test plate 2 is relatively long in the horizontal direction. Driving the test plate 2 with the double-rod cylinder 3 can make the movement of the test plate 2 stable.

[0047] Please refer to Figure 1 and Figure 3 The test plate 2 has a connecting groove 22 on the side facing the first rod 11. Laterally, the connecting groove 22 is located in the exact center of the test plate 2. The ends of the two piston rods of the double-rod cylinder 3 are fixed with mating plates 31, which are located within the connecting groove 22. This allows the mating plates 31 to be accurately connected to the center of the test plate 2, ensuring the test plate 2 remains balanced during movement.

[0048] Please refer to Figure 2 The test plate 2 is equipped with rollers 23, the bottom surface of which protrudes from the bottom surface of the test plate 2. When the demolding pneumatic clamp is installed on the substrate, the rollers 23 can abut against the substrate, while the test plate 2 will not abut against the substrate. This avoids friction between the test plate 2 and the substrate, allowing the test plate 2 to move smoothly.

[0049] Please refer to Figure 1 The demolding pneumatic clamp also includes a connecting plate 4, a first screw, and a second screw. The bottom surface of the connecting plate 4 is in contact with the top surface of the first rod 11, and the bottom surface of the connecting plate 4 extends into the receiving space 13 and is in contact with the top surface of the double-rod cylinder 3. The first screw passes through the connecting plate 4 from top to bottom and is threadedly connected to the first rod 11. The second screw passes through the connecting plate 4 from top to bottom and is threadedly connected to the cylinder body of the double-rod cylinder 3. With the above structure, the double-rod cylinder 3 can be stably connected to the support frame 1.

[0050] Please refer to Figure 1 The bottom surface of the double-rod cylinder 3 is flush with the bottom surface of the first rod 11. When the demolding pneumatic clamp is installed on the substrate, the double-rod cylinder 3 can fit against the substrate and the cylinder is clamped between the substrate and the connecting plate 4, which is stable and reliable.

[0051] Please refer to Figure 1 and Figure 4 Each second rod 12 has two positioning bosses 121 on its inner side at the end furthest from the first rod 11. The two positioning bosses 121 are arranged longitudinally at intervals, forming a positioning groove 122 between them. The positioning groove 122 forms an insertion port 1221 at the top surface of the second rod 12, through which the electronic device 100 can enter the positioning groove 122. The two positioning grooves 122 cooperate to clamp both ends of the electronic device 100. The cooperation of the two positioning grooves 122 can fix the electronic device 100 stably. When the double-rod cylinder 3 drives the test plate 2 to dock with the electronic device 100, it can prevent the electronic device 100 from shifting longitudinally.

[0052] Please refer to Figure 4 The insertion port 1221 has an inclined surface along its circumference to facilitate the insertion of the electronic device 100, so that the electronic device 100 can be placed into the insertion port 1221.

[0053] Two through-beam sensors (not shown in the figure) are installed at the two insertion ports 1221. The through-beam sensors are electrically connected to the double-rod cylinder 3 to control the action of the double-rod cylinder 3. This ensures that the double-rod cylinder 3 can only be activated for insertion after the electronic device 100 is installed in place, avoiding damage to the electronic device caused by forced insertion.

[0054] Please refer to Figure 1 The first rod 11 and the two second rods 12 are integrally formed and connected in a U-shape. This eliminates the hassle of assembling the support frame 1, and the support frame 1 is sturdy.

[0055] Working principle of the pneumatic demolding fixture in the preferred embodiment of this utility model:

[0056] The two ends of the electronic device 100 are inserted into the two positioning slots 122 through the two insertion ports 1221 respectively. After the through-beam sensor detects that the electronic device 100 is installed in place, the double-rod cylinder 3 is activated. The piston rod of the double-rod cylinder 3 pushes the test board 2 closer to the electronic device 100 and connects the plug 21 on the test board 2 with the socket on the electronic device 100. After the test is completed, the double-rod cylinder 3 drives the test board 2 away from the electronic device 100, thereby separating the plug 21 on the test board 2 from the socket on the electronic device 100. The two ends of the electronic device 100 are then removed from the two positioning slots 122 respectively, and the next electronic device 100 can be tested.

[0057] This is the working principle of the demolding pneumatic clamp in this preferred embodiment.

[0058] This utility model discloses a pneumatic demolding fixture and testing device. After fixing the electronic device between two second rods, a double-rod cylinder automatically drives the test board close to the electronic device to mate the two plugs with the two sockets of the electronic device, effectively improving efficiency and reducing the workload of operators. In addition, the test board has two plugs arranged laterally, so the test board is relatively long in the lateral direction. Driving the test board with a double-rod cylinder ensures stable movement of the test board.

[0059] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the concept of the technical solution of the present invention, should be included within the scope of protection of the present invention.
