Detailed Implementation Methods

[0022] To further illustrate the technical means and effects of the present invention, the following detailed description is provided in conjunction with the embodiments of the present invention and their accompanying drawings.

[0023] This invention provides a product deformation detection device for detecting the deformation of product 4. The detection device includes:

[0024] A positioning fixture 1 includes a base 10 and a positioning plate 11. The positioning plate 11 is detachably mounted on the base 10 and is used to place the product 4 to be tested. The positioning plate 11 is provided with a plurality of first positioning blocks 110. The first positioning blocks 110 are arranged around the positioning plate 11 according to the shape of the product 4 and are used to position the product 4. The positioning plate 11 is provided with a hollow groove 111 corresponding to the position of the product 4 to be tested. The side of the positioning plate 11 away from the product 4 is provided with a detection element 112 corresponding to the position of the hollow groove 111. The detection element 112 is used to detect the deformation data of the corresponding position of the product 4. The deformation data of a certain position of the product 4 measured by the detection element 112 is the distance between the position of the product 4 on the side of the positioning plate 11 where the product 4 is placed and the side of the positioning plate 11 where the product 4 is placed.

[0025] A controller (not shown in the figure) is electrically connected to the detection element 112. The controller is used to determine whether the deformation detection result of the product 4 to be tested is qualified based on the deformation data detected by the detection element 112.

[0026] The positioning plate 11 is further provided with an auxiliary positioning component 12, which includes a driving element 120 and a second positioning block 121. The driving element 120 is fixed to the positioning plate 11 and electrically connected to the controller. The second positioning block 121 is fixed to the driving end of the driving element 120. The driving element 120 is used to drive the second positioning block 121 to move closer to or further away from the product 4, thereby assisting in clamping and positioning the product 4 and improving detection accuracy.

[0027] The positioning plate 11 and the positioning fixture base 10 are provided with screw holes 13 at corresponding positions. The positioning plate 11 and the positioning fixture base 10 are installed and fixed by screws 130, which facilitates the disassembly and replacement of the positioning plate 11. When inspecting products 4 with different shapes or when inspecting the deformation of products 4 at different positions, the deformation of products 4 can be inspected by replacing the corresponding positioning plate 11, thereby improving the adaptability of the inspection device.

[0028] The positioning plate 11 is equipped with a sensor (not shown in the figure). The sensor is located on the side of the positioning plate 11 where the product 4 is placed. The sensor is used to detect whether the product 4 to be tested is placed on the positioning plate 11. The sensor is electrically connected to the controller.

[0029] The positioning plate 11 is provided with multiple detection elements 112. The controller includes a storage unit and a judgment unit. The storage unit is used to pre-store standard tolerance range data. The judgment unit is connected to the storage unit and is used to compare the deformation data with the standard tolerance range to determine whether the product 4 is qualified. The storage unit can be a register, and the judgment unit can be a central processing unit. The two can be integrated into a PCB. If the deformation data detected by all detection elements 112 is within the standard tolerance range, the deformation test result of the product 4 is qualified. If the deformation data detected by any one of the detection elements 112 is not within the standard tolerance range, the deformation test result of the product 4 is unqualified. In this embodiment, the standard tolerance range is 0.05 to 0.3 mm.

[0030] The product deformation detection device further includes a frame 2 and an operating table 3. The operating table 3 is equipped with a conveying mechanism 31, which is electrically connected to the controller. The positioning fixture 1 is located at the conveying end of the conveying mechanism 31. The conveying mechanism 31 is used to convey the positioning fixture 1 to move back and forth linearly on the operating table 3. The two ends of the operating table 3 corresponding to the moving direction of the conveying end of the conveying mechanism 31 are the loading station and the unloading station, respectively.

[0031] The conveying mechanism 31 is provided with guide rails 32 on both sides. The guide rails 32 are provided on the operating table 3 and are parallel to the moving direction of the conveying end of the conveying mechanism 31. The positioning fixture base 10 is provided with a guide slider 100. The guide slider 100 is slidably disposed on the guide rail 32. The guide rail 32 and the guide slider 100 cooperate to guide the moving direction of the positioning fixture 1.

[0032] The product deformation detection device further includes a display 20 and a voice broadcaster 21. The display 20 and the voice broadcaster 21 are mounted on the frame 2 and are electrically connected to the controller. The display 20 is used to display the deformation data detected by each detection element 112, as well as the result of the controller comparing the deformation data detected by each detection element 112 with the standard tolerance range data. The voice broadcaster 21 is used to broadcast the detection result of the product 4 deformation.

[0033] The operating table 3 is equipped with a barcode scanning device 30 near the loading station. The barcode scanning device 30 is electrically connected to the controller. The barcode scanning device 30 is used to scan and identify the markings on the product 4 to be inspected, so as to transmit the identified product information to the controller. The markings can be QR codes or barcodes affixed to the product. The product information includes product name, serial number and other information.

[0034] The product deformation detection device frame 2 is equipped with a safety light curtain 22, which is electrically connected to the controller. The safety light curtain 22 is positioned on both sides of the frame 2 near the loading station to prevent operators from accidentally entering the detection area and to improve detection accuracy and safety.

[0035] In this embodiment, the detection element 112 is a displacement sensor, the sensor is an infrared sensor, the driving element 120 is a cylinder, and the conveying mechanism 31 is a linear slide module.

[0036] The working process of this invention is as follows: First, the product 4 to be inspected is transported to the barcode scanning device 30 at the loading station by manual labor or a handling device for barcode scanning. The barcode scanning device 30 identifies the product information of the product 4 to be inspected and sends it to the controller. Then, the product 4 to be inspected is placed between the first positioning blocks 110 on the positioning plate 11 by manual labor or a handling device. The driving element 120 of the positioning component 12 drives the second positioning block 121 to move towards the product 4 to clamp and position the product 4. After the sensor on the positioning plate 11 detects the product 4 to be inspected, each detection element 112 detects the corresponding position of the product 4 and obtains the deformation data of the corresponding position. The deformation data is then sent to the controller. The controller compares the deformation data detected by each detection element 112 with the standard tolerance range data and judges the deformation detection result of the product 4. The display 20 displays the deformation data detected by each detection element 112 and the result of the controller comparing the deformation data detected by each detection element 112 with the standard tolerance range data.

[0037] If the deformation data detected by each of the detection elements 112 are within the standard tolerance range, the deformation test result of the product 4 is qualified. If the deformation data detected by any one of the detection elements 112 is not within the standard tolerance range, the deformation test result of the product 4 is unqualified. Finally, the voice broadcaster 21 broadcasts the test results. After the test is completed, the conveying mechanism 31 transports the positioning fixture 1 and the product 4 to the unloading station. The positioning component 12 releases the product 4, and the manual or handling device takes away the tested product 4 and sorts it into good / defective products according to the test results.

[0038] The beneficial effects of the present invention are that it can automatically detect the deformation of product 4. When detecting different products 4 or different detection positions of product 4, rapid detection can be achieved by configuring and replacing the corresponding positioning plate 11, which improves the adaptability, detection efficiency and detection accuracy of the detection device. In addition, the deformation detection device of the present invention can be connected to automated processing equipment of other processes of the product, saving manpower and accelerating the automated production process of product 4.

[0039] It should be noted that the present invention is not limited to the above embodiments. Any simple modifications, equivalent changes and alterations made by those skilled in the art to the above embodiments based on the technical solutions of the present invention shall fall within the protection scope of the present invention.
