[0028] The present utility model will be further described below in conjunction with the accompanying drawings and the detailed implementation manner.

[0029] A glue separation detection device 2 for a special magnet assembly 7, as Figures 1 to 10 shown, includes a clamping device 1, a detection device 2 and an induction device 3; a clamping part is provided on the clamping device 1, and the clamping part is used to clamp the magnet at one end of the magnet assembly 7, and the bonding part of the magnet assembly 7 and the magnet at the other end of the magnet assembly 7 extend out from the clamping part and are located between the detection device 2 and the induction device 3; a detection part is provided on the detection device 2, and the detection part is used to abut against and push the magnet at the other end of the magnet assembly 7, and the induction device 3 is fixedly arranged along the movement path of the detection part for the detection part to push away the magnet at the other end of the magnet assembly 7 and abut against and trigger.

[0030] In this embodiment, the magnet assembly 7 to be detected is formed by two magnets with the same size and opposite polarities adsorbed along the short side of the magnet. Therefore, the magnet at one end of the magnet assembly 7 is clamped by the clamping part on the clamping device 1, and the bonding part of the magnet assembly 7 and the magnet at the other end of the magnet assembly 7 extend out from the clamping part and are located between the detection device 2 and the induction device 3. The detection part of the detection device 2 is used to abut against and push the magnet at the other end of the magnet assembly 7 to detect whether the magnet assembly 7 is firmly bonded. When the magnet assembly 7 is not firmly bonded and causes glue separation, the detection part will push away the magnet at the other end of the magnet assembly 7 and continue to move to trigger the induction device 3. At this time, the entire device will stop working, realizing the glue separation detection of the magnet assembly 7. The entire detection process realizes semi-automation, reduces the workload of manual operation, and improves the efficiency of glue separation detection.

[0031] As Figure 1 and Figure 4 shown, it further includes a bottom plate 4. The clamping device 1 is arranged on the front side of the bottom plate 4, the induction device 3 is arranged on the rear side of the bottom plate 4, and the detection device 2 is arranged above the induction device 3. In order to facilitate the operator to place the magnet assembly 7, in this embodiment, the clamping device 1 is arranged on the front side of the bottom plate 4, the induction device 3 is arranged on the rear side of the bottom plate 4, and the detection device 2 is arranged above the induction device 3. The operator only needs to stand in front of the clamping device 1 to place the magnet assembly 7 or take out the magnet assembly 7 that has completed the glue separation detection.

[0032] As Figure 2 and Figure 3 shown, the clamping device 1 includes a base 10, a support plate 11, a first downward pressing cylinder 12, a lower pressing plate 13 and a jig plate 14. The support plate 11 is vertically fixed on the base 10. The first downward pressing cylinder 12 is provided at the top of the support plate 11, and the output end of the first downward pressing cylinder 12 is arranged vertically downward. The lower pressing plate 13 is fixedly arranged at the output end of the first downward pressing cylinder 12. The jig plate 14 is fixedly arranged on the base 10, on one side of the support plate 11 corresponding to the lower pressing plate 13. A jig groove 15 is formed on the jig plate 14. The lower pressing plate 13 abuts against the jig plate 14, and a clamping portion is formed between the lower pressing plate 13 and the jig groove 15. The magnet assembly 7 is placed in the jig groove 15. One end of the magnet of the magnet assembly 7 abuts against the closed end of the jig groove 15, and the lower pressing plate 13 abuts against the magnet at one end of the magnet assembly 7 for clamping the magnet assembly 7. The bonding portion of the magnet assembly 7 and the magnet at the other end of the magnet assembly 7 extend out from the open end of the jig groove 15.

[0033] In this embodiment, the output end of the first downward pressing cylinder 12 is arranged vertically downward. The first downward pressing cylinder 12 moves downward to drive the lower pressing plate 13 to abut against the jig plate 14 or separate from the jig plate 14. A jig groove 15 is formed on the jig plate 14. The lower pressing plate 13 abuts against the jig plate 14, and a clamping portion is formed between the lower pressing plate 13 and the jig groove 15. The jig groove 15 of this embodiment is arranged along the length direction of the jig plate 14. Multiple magnet assemblies 7 can be accommodated in the jig groove 15. The jig groove 15 is provided with a closed end and an open end. Multiple magnet assemblies 7 are neatly placed in the jig groove 15. One end of the magnet of the magnet assembly 7 abuts against the closed end of the jig groove 15, and the bonding portion of the magnet assembly 7 and the magnet at the other end of the magnet assembly 7 extend out from the open end of the jig groove 15, so that the debonding detection of multiple magnet assemblies 7 can be carried out at one time, improving the detection efficiency.

[0034] As Figure 2 and Figure 3 shown, the height of the jig groove 15 of this embodiment matches the height of the magnet assembly 7, and the size of the lower pressing plate 13 matches the size of the jig plate 14, ensuring that after the magnet assembly 7 is placed in the jig groove 15, the lower pressing plate 13 can stably press the magnet at one end of the magnet assembly 7, so that when the detection device 2 performs debonding detection, the magnet assembly 7 will not loosen and affect the detection effect. In other embodiments, the size of the lower pressing plate 13 can also be set to match the size of the jig groove 15, so that the lower pressing plate 13 can press the magnet at one end of the magnet assembly 7.

[0035] As Figure 1 and Figure 4As shown, the detection device 2 includes a support backplane 21, a second pressing cylinder 22, an assembly backplane 23, a compression spring 24, and a detection block 25. In this embodiment, the support backplane 21 is vertically arranged on the bottom plate 4. The second pressing cylinder 22 is fixed at the top of the support backplane 21, and the output end of the second pressing cylinder 22 is arranged vertically downward. One side of the assembly backplane 23 is arranged at the output end of the second pressing cylinder 22. A plurality of limiting bumps 26 are arranged on the other side of the assembly backplane 23. A plurality of detection blocks 25 are slidably arranged on the other side of the assembly backplane 23, below the limiting bumps 26. A compression spring 24 is arranged between the upper end of the detection block 25 and the limiting bump 26. The detection part is arranged at the lower end of the detection block 25. Seven detection blocks 25 are arranged in this embodiment, but it is not limited thereto. The detection parts on each detection block 25 respectively abut against the magnets at the other end of a magnet assembly 7. Since there is a certain distance between the detection parts, the multiple magnet assemblies 7 in the jig groove 15 are in a grouped detection mode. The second pressing cylinder 22 presses down to drive the detection part of the detection block 25 to perform the glue opening detection in a cycle until all the magnet assemblies 7 are detected.

[0036] As Figure 5 shown, the detection part in this embodiment is a long strip-shaped convex plate 27. One end of the convex plate 27 is connected to the lower end of the detection block 25, and the other end of the convex plate 27 abuts against the magnet at the other end of the magnet assembly 7. The cross-sectional dimension of this convex plate matches the dimension of the magnet at the other end of the magnet assembly 7. In other embodiments, the convex plate 27 can also be set into other shapes such as a convex column.

[0037] As Figure 5 , Figure 8 and Figure 10 shown, it further includes a slider 28. A plurality of slide rails 29 are arranged on the other side of the assembly backplane 23 in the vertical direction. A plurality of sliders 28 are slidably arranged on the plurality of slide rails 29. A plurality of detection blocks 25 are fixedly arranged on the plurality of sliders 28. In this embodiment, the number of the sliders 28 and the slide rails 29 are both set to seven, but it is not limited thereto. When the second pressing cylinder 22 of the detection device 2 presses down to drive the detection part of the detection block 25 to abut against the magnet, when the magnet assembly 7 is firmly bonded, the detection block 25 will move upward along the slide rail 29 through the slider 28 to compress the compression spring 24. When the magnet assembly 7 is not firmly bonded, the magnet at the other end of the magnet assembly 7 will be pushed away by the convex plate 27 of the detection part, and the convex plate 27 will continue to move downward to trigger the induction device 3, causing the entire device to stop working and alarm. In this embodiment, the operator can adjust the pressing force of the second pressing cylinder 22 and the compression strength of the compression spring 24 according to the size of the magnet assembly 7 to meet the glue opening detection requirements.

[0038] As Figure 1 and Figure 4As shown, the shape of the support backplane 21 in this embodiment is an inverted L shape, which saves materials while ensuring the firm installation of the second pressing cylinder 22. In other embodiments, it can also be set to other shapes according to actual requirements.

[0039] As Figure 4 shown, the induction device 3 in this embodiment includes an optical fiber sensor 31 and a fixed seat 32. The fixed seat 32 is fixedly arranged along the movement path of the detection part, located below the detection device 2. The optical fiber sensor 31 is fixedly arranged on the fixed seat 32 and is used to trigger by abutting against the detection part. The optical fiber sensor 31 has high sensitivity and fast measurement speed. When the detection part of the detection device 2 touches the optical fiber sensor 31, the entire device can stop working immediately and give an alarm, with a clever design.

[0040] As Figure 1 shown, it further includes a guide rail 5 and a motor 6. The guide rail 5 and the motor 6 are respectively fixedly arranged. The clamping device 1 is arranged on the guide rail 5. The motor 6 drives the guide rail 5 to move, thereby driving the magnet assembly 7 that has completed the debonding detection on the clamping device 1 to move along the guide rail 5. In this embodiment, the detection parts on each detection block 25 respectively abut against the magnets at the other end of a magnet assembly 7. Since there is a certain distance between the detection parts, the multiple magnet assemblies 7 in the fixture groove 15 are in a grouped detection mode. Therefore, this embodiment is provided with a guide rail 5 to move the magnet assembly 7 on the clamping device 1. When the detection of one group of magnets among the multiple magnet assemblies 7 is completed, the motor 6 will drive the guide rail 5 to move, thereby driving the magnet assembly 7 that has completed the debonding detection on the clamping device 1 to move along the guide rail 5, and then the detection of the next group of magnet assemblies 7 is carried out until the detection of all magnet assemblies 7 is completed.

[0041] The usage process of the present utility model is as follows:

[0042] First, place the magnet assemblies 7 neatly in the fixture groove 15 of the clamping device 1. As Figure 6 shown, press the start button (not shown in the figure), and the first pressing cylinder 12 presses down to drive the lower pressing plate 13 to abut against the magnet at one end of the magnet assembly 7 for fixation and wait for detection.

[0043] The second pressing cylinder 22 of the detection device 2 presses down to drive the detection block 25 to move. The convex plate 27 on the detection block 25 abuts against the magnet at the other end of the magnet assembly 7. When the magnet assembly 7 is firmly bonded, the detection block 25 will move upward along the slide rail 29 through the slider 28, causing the compression spring 24 to be compressed. As Figure 7 and Figure 8 shown, when the magnet assembly 7 is not firmly bonded, the magnet at the other end of the magnet assembly 7 will be pushed away by the convex plate 27 of the detection part, and the convex plate 27 will continue to move downward to trigger the induction device 3, causing the entire device to stop working and give an alarm. As Figure 9 andFigure 10 as shown

[0044] Since there is a certain spacing distance between each convex plate 27 of the detection part, the multiple magnet components 7 in the jig groove 15 are in a grouped detection mode. After one group of magnets of the multiple magnet components 7 is detected, the motor 6 will drive the guide rail 5 to move, thereby driving the magnet component 7 that has completed the debonding detection on the clamping device 1 to move along the guide rail 5, and then the detection of the next group of magnet components 7 is carried out until all the magnet components 7 are detected.

[0045] The orientation terms mentioned in this specification are defined relative to the structures shown in the respective drawings. They are relative concepts and may therefore change accordingly depending on their different positions and usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0046] The above are only the preferred embodiments of the present invention and do not limit the design of this case. All equivalent changes made according to the key design of this case fall within the protection scope of this case.
