The driving component of the first cylinder 401 is horizontally arranged.

[0024] The mounting device 5 includes a transmission component 501, a lead screw 502, a first motor 503, and a second cylinder 504. The first motor 503 is located inside the test chamber 2 on the side away from the mounting chamber 3. One end of the lead screw 502 is fixedly connected to the output end of the first motor 503, and the other end of the lead screw 502 is rotatably mounted on the inner wall of the mounting chamber 3. The transmission component 501 is rotatably mounted on the lead screw 502, and the second cylinder 504 is located in the middle of the front inner wall of the test chamber 2.

[0025] Furthermore, the transmission component 501 includes a base plate 6, a sliding plate 7, and a push plate 8. A sliding cavity 9 is provided in the base plate 6. The sliding plate 7 is slidably disposed in the sliding cavity 9. A spring 10 is fixedly disposed at the bottom of the sliding cavity 9. One end of the spring 10 is fixedly connected to the bottom of the sliding cavity 9, and the other end of the spring 10 is fixedly connected to one end of the sliding plate 7. The push plate 8 is vertically fixedly disposed on the sliding plate 7.

[0026] Furthermore, a through groove 11 is provided between the test chamber 2 and the installation chamber 3, connecting the test chamber 2 and the installation chamber 3. The through groove 11 is L-shaped and allows the transmission component 501 to pass through. A limit post 12 is horizontally provided at the bottom of the test box 1, and the limit post 12 passes horizontally through the transmission component 501. The limit post 12 can stabilize the transmission of the transmission component 501.

[0027] Furthermore, a vacuum pump 13 is installed inside the test chamber 2, and the vacuum pump 13 is connected to the suction cup 402 via an air pipe. An ultraviolet lamp 14 is installed on the top of the test chamber 2, and an observation window 15 is installed on the outside of the test box 1 located in the test chamber 2. By irradiating with ultraviolet light 14, the degree of curing of the glue can be determined, and the condition of the component to be tested can be directly observed through the observation window 15.

[0028] Furthermore, the top of the installation compartment 3 is provided with an opening 16. Workers can place the component to be tested through the opening 16.

[0029] In this embodiment of the utility model, please refer to Figure 1-5 The working principle is as follows: When the staff needs to test the quality of the glue, the test component is placed on the transmission component 501 in advance. The initial position of the transmission component 501 is set in the installation chamber 3. The test component is placed on the transmission component 501 located in the installation chamber 3 through the opening 16 above the installation chamber 3. The test component is placed on the sliding plate 7 on the side of the push plate 8 away from the second cylinder 504. At this time, the first motor 503 is started, and the first motor 503 drives the lead screw 502 to rotate. At this time, the transmission component 501 is driven by the lead screw 502 and can be transmitted to the test chamber 2 through the through groove 11. When the push plate 8 of the transmission component 501 is transmitted to the test chamber 2 and is located in front of the second cylinder 504, the second cylinder 504 is started. The drive component of the second cylinder 504 will push the push plate 8. At this time, the push plate 8 will overcome the tension of the spring 10 in the sliding cavity 9 under the pushing force of the second cylinder 504, so that the sliding plate 7 will be pulled out from the sliding cavity 9. At this time, the test component on the sliding plate 7 will be pushed to the test device 4. At this point, the first cylinder 401 is activated, and its driving component pushes the suction cup 402 to both sides of the test component. After the suction cup 402 clamps the test component, the vacuum pump 13 is started, allowing the suction cup 402 to completely clamp the test component. Then, the ultraviolet lamp 14 is turned on to observe the degree of adhesive curing. After the adhesive has completely cured, the first cylinder 401 is activated again, and the data from the tension sensor 403 on the driving component of the first cylinder 401 is recorded, thus quickly completing a set of adhesive quality tests. After the test is completed, the vacuum pump 13 is turned off, causing the test component to detach from the suction cup 402. Then, the second cylinder 504 is turned off. After the push plate 8 loses the push from the driving component of the second cylinder 504, the sliding plate 7 is driven by the tension of the spring 10 in the sliding cavity 9. At this time, a portion of the sliding plate 7 is retracted into the sliding cavity 9, and the transmission component 501 can then transmit the adhesive back to the mounting chamber 3 via the through slot 11, thus completing a full round of adhesive testing.
