Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to a device for detecting sheet metal deformation and adhesive residue. Background Technology

[0002] The Chinese utility model patent with patent number ZL202222076366.X and patent name, entitled "A Device for Detecting Missing Adhesive in Backlights of Vehicle-Mounted Products," specifically discloses the following technical solution: A device for detecting missing adhesive in backlights of vehicle-mounted products includes a horizontally arranged detection plate, with a contoured test cavity at the upper end of the detection plate. Several positioning blocks are installed on the upper ends of the four edges of the contoured test cavity. Several spring detection pins arranged in a convex shape are installed on the upper end of the contoured test cavity. The spring detection pins are connected to a control box located on the lower end of the detection plate. The control box is connected to an indicator light module located on the side of the detection plate. The indicator light module has indicator lights arranged in a row at the upper end, corresponding to and matching the spring detection pins.

[0003] When performing the above-mentioned detection operation for the backlight of automotive products with missing adhesive, the product is first placed in the contour test chamber and positioned by the positioning block. Then, the conductive adhesive position on the product is tested by the spring detection pin. Since the spring detection pin is electrically connected to the control box, and the control box is connected to the indicator light module, when all the indicator lights in the indicator light module are lit, it proves that the conductive adhesive on the product is in place. Conversely, when one of the indicator lights in the indicator light module is not lit, the corresponding spring detection pin can be quickly found according to the not lit indicator light, so that the position of the missing adhesive on the product can be quickly found.

[0004] It should be noted that the aforementioned adhesive residue detection device for backlights of automotive products can only detect adhesive residue (i.e., back adhesive residue detection) and cannot simultaneously detect product deformation, making its function relatively limited. Utility Model Content

This sheet metal deformation and adhesive backing failure detection device has a novel structural design, multiple functions, and can simultaneously detect adhesive backing failure and deformation of sheet metal parts.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution.

Detailed Implementation

[0022] The present invention will now be described in conjunction with specific embodiments.

[0023] Example 1, as Figure 1 and Figure 2 As shown, a sheet metal part deformation and adhesive backing leakage detection device includes a product placement plate 1, a product placement area 11 is provided on the upper surface of the product placement plate 1, and a plurality of product positioning blocks 2 are arranged at intervals around the product placement area 11 on the upper surface of the product placement plate 1; an adhesive leakage detection component 3 is installed in the product placement area 11 of the product placement plate 1 corresponding to the adhesive backing position of the sheet metal part.

[0024] Among them, such as Figure 1 and Figure 2 As shown, the sheet metal deformation and adhesive leakage detection device also includes an adhesive leakage indicator light 4 and a controller. The adhesive leakage detection component 3 and the adhesive leakage indicator light 4 are electrically connected to the controller.

[0025] Furthermore, such as Figure 1 and Figure 2 As shown, the product placement area 11 of the product placement plate 1 is also equipped with several fiber optic displacement sensors 5, and each fiber optic displacement sensor 5 is electrically connected to the controller.

[0026] Furthermore, such as Figure 1 and Figure 2 As shown, an indicator light mounting block 6 is screwed onto the edge of the product placement plate 1. A glue leakage indicator light 4 is mounted on the indicator light mounting block 6. A deformation indicator light 7 is mounted on the side of the glue leakage indicator light 4 on the indicator light mounting block 6. The deformation indicator light 7 is also electrically connected to the controller.

[0027] In the process of inspecting sheet metal products using the sheet metal deformation and adhesive backing failure detection device of this embodiment, the sheet metal product is first placed in the product placement area 11 of the product placement plate 1. The sheet metal product is positioned by several product positioning blocks 2 to ensure that the sheet metal product is accurately placed in the product placement area 11. After the sheet metal product is positioned in the product placement area 11, the adhesive backing failure detection component 3 detects the adhesive backing position of the sheet metal product to detect whether the sheet metal product has adhesive backing. When the sheet metal product has no adhesive backing, the adhesive backing failure detection component 3 feeds back a signal to the controller. The controller activates the adhesive leakage indicator 4 to alert the inspector that the sheet metal part being inspected has not been properly adhesive-backed, allowing for subsequent re-adhesive application. Simultaneously, multiple fiber optic displacement sensors 5 detect the distance to their respective detection positions on the sheet metal part, and each sensor feeds this distance information back to the controller. The controller uses this information to determine if the sheet metal part is deformed. If deformation is detected, the controller activates the deformation indicator 7 to alert the inspector, allowing for subsequent rework.

[0028] It should be emphasized that the sheet metal deformation and adhesive backing leakage detection device of this embodiment can realize the function of detecting adhesive backing leakage of sheet metal products on the one hand, and the function of detecting sheet metal deformation on the other hand. That is, the sheet metal deformation and adhesive backing leakage detection device of this embodiment can simultaneously detect adhesive backing leakage and deformation of sheet metal products. Therefore, the sheet metal deformation and adhesive backing leakage detection device of this embodiment has the advantages of novel structural design and multiple functions.

[0029] Example 2, as Figure 1 and Figure 2 As shown, the difference between this embodiment 2 and embodiment 1 is that: the product placement plate 1 is equipped with a number of spaced position sensors 8 in the product placement area 11, and each position sensor 8 is electrically connected to the controller.

[0030] Specifically, position sensor 8 is a reflective photoelectric sensor.

[0031] When the inspector positions the sheet metal part in the product placement area 11 of the product placement plate 1, the sheet metal part deformation and adhesive backing failure detection device of this embodiment 2 uses several position sensors 8 to detect whether the sheet metal part is placed in place. When all position sensors 8 detect that the sheet metal part is placed, the controller then performs adhesive backing failure detection and deformation detection.

[0032] Example 3, as Figure 1 and Figure 2As shown, the difference between this embodiment 3 and embodiment 1 is that the glue leakage detection component 3 includes a probe mounting block 31 that is screwed and fastened to the product placement plate 1. The probe mounting block 31 is equipped with two spaced elastic probes 32, and each elastic probe 32 is electrically connected to the controller.

[0033] When the sheet metal part is placed in the product placement area 11, if there is adhesive on the adhesive backing area of ​​the sheet metal part, the two elastic probes 32 will directly contact the adhesive backing, and the two elastic probes 32 will not be electrically connected. If there is no adhesive backing on the adhesive backing area of ​​the sheet metal part, the two elastic probes 32 will directly contact the sheet metal part, and the two elastic probes 32 will be electrically connected. The controller determines whether there is adhesive backing on the adhesive backing area of ​​the sheet metal part based on the electrical connection of the two elastic probes 32, thereby realizing the detection of missing adhesive backing.

[0034] Example 4, as Figure 1 and Figure 2 As shown, the difference between this embodiment 4 and embodiment 1 is that: a base 9 is installed below the product placement plate 1. The base 9 includes a bottom plate 91 and four side plates 92 that are screwed and fastened to the bottom plate 91 respectively. The product placement plate 1 is screwed and fastened to the upper end of the side plates 92.

[0035] The base plate 91, the product placement plate 1, and the four side plates 92 together form an inner cavity 93, and the controller is located in the inner cavity 93.

[0036] The above description is only a preferred embodiment of this utility model. For those skilled in the art, based on the concept of this utility model, there will be changes in the specific implementation methods and application scope. The content of this specification should not be construed as a limitation of this utility model.
