[0033] like Figure 1-8 As shown, in one embodiment of the utility model, a speaker bracket broken glue detection device is provided, including a first conveying mechanism 10, a second conveying mechanism 20, a detection platform 30, a first pushing mechanism 40, a detection component 50, a material storage platform 60 and a second pushing mechanism 70.

[0034] The tail end of the first conveying mechanism 10 is provided with a discharging station 11, and the starting end of the second conveying mechanism 20 is provided with a feeding station 21. The first conveying mechanism 10 and the second conveying mechanism 20 both use belt conveyors. The detection platform 30 is provided between the first conveying mechanism 10 and the second conveying mechanism 20. The detection platform 30 is provided with a detection station 31, and the detection station 31 is connected to the discharging station 11 and the feeding station 21 respectively.

[0035] The first pushing mechanism 40 is used to push the workpiece in the discharging station 11 (i.e., the speaker bracket after gluing) into the inspection station 31, or push the workpiece in the inspection station 31 into the feeding station 21. The inspection component 50 is used to inspect the workpiece in the inspection station 31. The inspection component 50 includes a camera 51, etc. The inspection component 50 is a prior art and will not be described in detail in this embodiment. The storage platform 60 is connected to the inspection platform 30, and the storage platform 60 is used to store unqualified workpieces. The second pushing mechanism 70 is used to push the workpiece in the inspection station 31 onto the storage platform 60.

[0036] The speaker bracket after gluing is transported to the discharging station 11 by the first conveying mechanism 10, and then the first pushing mechanism 40 pushes the speaker bracket to the detection station 31 on the detection platform 30, waiting for the camera 51 to identify the four gluing positions on the speaker bracket. If the detection passes, the first pushing mechanism 40 will push the speaker bracket to the feeding station 21 of the second conveying mechanism 20, and the second conveying mechanism will transport the speaker to the next process.

[0037] If the test fails, that is, it is detected that the glue is broken at the gluing position, the second pushing mechanism 70 will push the speaker bracket in the detection station 31 to the material storage platform 60 for buffering, waiting for the operator to transport it back to the gluing process for gluing operation.

[0038] The first conveying mechanism 10, the second conveying mechanism 20, the first pushing mechanism 40, the detection assembly 50 and the second pushing mechanism 70 are all controlled by a controller (not shown in the drawings). The controller may be a PLC, etc., which will not be described in detail here.

[0039] The present embodiment discloses a speaker bracket broken glue detection device, which designs the detection platform 30 between the first conveying mechanism 10 and the second conveying mechanism 20, and the first pushing mechanism 40 can push the workpiece in the discharge station 11 to the detection station 31. If the detection passes, the first pushing mechanism 40 will push the workpiece with qualified glue to the feeding station 21, and the second conveying mechanism 20 will transport it to the next production process. If the detection fails, the second pushing mechanism 70 will push the workpiece with broken glue to the storage platform 60. The speaker bracket broken glue detection device can remove the workpiece with unqualified glue through the reasonable arrangement of each mechanism to prevent it from flowing into the subsequent production process, reduce the occurrence of quality problems in the subsequent process, and improve product quality and production efficiency.

[0040] In one embodiment, the first pushing mechanism 40 includes a first cylinder 41, a first pushing block 42 and a first stopper 43. The first cylinder 41 is arranged on the side of the first conveying mechanism 10 away from the detection platform 30. The first pushing block 42 is arranged on the piston rod of the first cylinder 41. The moving direction of the first pushing block 42 is perpendicular to the conveying direction of the first conveying mechanism 10. The first stopper 43 is arranged on the first pushing block 42. When the first pushing block 42 pushes the workpiece in the unloading station 11 to the detection station 31, the first stopper 43 extends into the first conveying mechanism 10 and blocks the workpiece from entering the feeding station 21.

[0041] When the first cylinder 41 extends its piston rod, it will synchronously drive the first push block 42 and the first stop block 43 to move toward the detection platform 30. When the first push block 42 pushes the workpiece in the discharge station 11, the first stop block 43 will also block a workpiece adjacent to the workpiece, thereby preventing it from entering the discharge station 11. When the first cylinder 41 retracts its piston rod, the first push block 42 and the first stop block 43 will also gradually withdraw from the discharge station 11. In this way, the blocked workpiece will be transported to the discharge station 11 driven by the first conveying mechanism 10 to wait for detection.

[0042] In one embodiment, a first blocking surface 431 is provided on the side of the first stopper 43 facing away from the first cylinder 41, and the first blocking surface 431 is perpendicular to the conveying direction of the first conveying mechanism 10. The first stopper 43 is bent to form an extension block 44, and the extension block 44 is provided on the first stopper 43. The extension block 44 can not only realize the connection between the first stopper 43 and the first push block 42, but also increase the contact area between the first push block 42 and the workpiece, thereby improving the pushing effect on the workpiece in the unloading station 11 or the detection station 31.

[0043] In one embodiment, the two side plates of the first conveying mechanism 10 are respectively provided with a first notch 12 and a second notch 13, the first notch 12 and the second notch 13 are respectively connected to the feeding station 21, the second notch 13 is connected to the detection station 31, and the first push block 42, the first stop block 43 and the extension block 44 all extend into the first notch 12.

[0044] In one embodiment, the conveying direction of the first conveying mechanism 10 is opposite to that of the second conveying mechanism 20, and the material storage platform 60 is disposed between the first conveying mechanism 10 and the second conveying mechanism 20. The above structural design makes the overall structure of the detection device more compact and saves space.

[0045] In one embodiment, the second pushing mechanism 70 includes a second cylinder 71 and a second pushing block 72, wherein the second cylinder 71 is close to the detection station 31 and is located on the side of the detection platform 30 away from the material storage platform 60. The second pushing block 72 is disposed on the piston rod of the second cylinder 71, and the extension direction of the piston rod of the second cylinder 71 is parallel to the conveying direction of the second conveying mechanism 20.

[0046] The extension direction of the piston rod of the second cylinder 71 is perpendicular to that of the piston rod of the first cylinder 41. If it is detected that the glue is broken at the gluing position of the speaker bracket in the detection station 31, the second cylinder 71 will extend its piston rod, and the second push block 72 will push the speaker bracket to the material storage platform 60 for buffering, waiting for the operator to transport it back to the gluing process for gluing. Of course, in order for the second push block 72 to normally push the speaker bracket in the detection station 31, the width of the second push block 72 should be smaller than the width of the speaker bracket, so that the second push block 72 can avoid interference with the extension block 44.

[0047] In one embodiment, a material blocking mechanism 80 is provided on the detection platform 30 to block the workpiece in the detection station 31. The material blocking mechanism 80 includes a second block 81 and a third cylinder 82. The second block 81 is lifted and matched on the detection platform 30 and is close to the second conveying mechanism 20. The second block 81 is provided with a second blocking surface on the side facing the first conveying mechanism 10. The second blocking surface is perpendicular to the extension direction of the piston rod of the first cylinder 41. The top surface of the second block 81 can be flush with the table surface of the detection platform 30. The third cylinder 82 is provided below the detection platform 30, and the third cylinder 82 is used to drive the second block 81 to do lifting and lowering actions.

[0048] In the initial state, the second stopper 81 is extended out of the detection platform 30, that is, the horizontal height of the top surface of the second stopper 81 is higher than the horizontal height of the surface of the detection platform 30. When the extension block 44 pushes the speaker bracket in the discharging station 11 to the detection station 31, the speaker bracket will be blocked by the second stopper 81. In this way, under the joint action of the extension block 44 and the second stopper 81, the speaker bracket in the detection station 31 can be fixed, thereby improving the accuracy of the detection component 50 in detecting the gluing position.

[0049] If the test is qualified, the third cylinder 82 will drive the second stopper 81 to descend, so that the top surface of the second stopper 81 is flush with the surface of the test platform 30. In this way, the first cylinder 41 will push the speaker bracket from the test station 31 to the feeding station 21. If the test is unqualified, the third cylinder 82 will keep the second stopper 81 in the current state.

[0050] In one embodiment, a side plate of the second conveying mechanism 20 close to the detection platform 30 is provided with a third notch 22 , and the third notch 22 is connected to the feeding station 21 and the detection station 31 respectively.

However, it is understood that the embodiments of the present utility model can be practiced without these specific details. In some examples, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
