Description

Technical Field

[0001] The utility model belongs to the technical field of brake disc processing, and in particular relates to a brake disc spraying tool based on RFID. Background Art

[0002] The brake disc, also known as the brake disc, is an important component of the vehicle's braking system. When the wheel brakes during driving, the brake caliper clamps the brake disc to slow down or stop the vehicle. Its performance and reliability are related to the safety of the vehicle.

[0003] Brake discs are generally cast from iron materials. Car bodies are used outdoors, and iron is a material that is prone to rust. Therefore, brake discs are prone to rust if they are not surface treated. Currently, brake discs need surface spraying to prevent rust. At the same time, in order to meet the requirements for accurate traceability of brake disc quality, brake discs need to have a QR code to determine relevant information about the brake disc, so as to ensure that relevant information about the brake disc, such as production time, factory time, production serial number and related parameters, can still be determined based on the QR code information after leaving the factory.

[0004] In order to achieve accurate traceability, the brake disc needs to have relevant information printed on its surface in the form of a QR code before and after spraying, and the laser QR code information after painting needs to correspond to the QR code information before painting, so as to ensure that the relevant information of the brake disc can still be determined according to the QR code information after leaving the factory. Usually, the production process is to print the relevant information on the brake disc in the form of a QR code before spraying, temporarily store the relevant information before spraying, cover the QR code information during spraying, and call out the original QR code information after spraying, and print it on the brake disc by laser. RFID (Radio Frequency Identification, contactless automatic identification technology) technology is applied to the spraying process, and the storage function of the RFID chip is used to store the two-dimensional information before painting, and the RFID chip is read after painting to print the data, and the required information is engraved on the surface of the brake disc after painting, so that the QR code content before and after painting corresponds to each other, and the data is accurate. At the same time, it solves the pain point of long product switching time and improves production efficiency and quality. However, in the spraying environment, the chemical composition of the brake disc coating dry film includes flaky zinc powder and aluminum powder. The spray material mist flows in the spray box. After a period of use, the spray material sticks to the RFID electronic tag. Due to the sensitivity of RFID technology to metal, the barcode reader cannot read or may make errors, affecting quality and efficiency. Utility Model Content

[0005] The purpose of the utility model is to overcome the defects of the prior art and provide a brake disc spraying tooling based on RFID to solve the problem that the contents of the two-dimensional code of the brake disc before and after painting correspond to each other in the spraying environment, and the RFID electronic tag is covered with spraying material during the spraying production, resulting in the code reader being unable to read or error, thus affecting the quality and efficiency.

[0007] A brake disc spraying tool based on RFID, comprising:

[0008] Spraying tooling;

[0011] The driving mechanism is arranged on the spraying tool, the output end of the driving mechanism is connected to the RFID shell, and the driving mechanism drives the RFID shell to cover or reveal the RFID chip tag.

[0012] In one of the embodiments, a groove matching the shape of the RFID chip tag is provided on the side of the spraying tool, and the RFID chip tag is installed in the groove.

[0013] In one of the embodiments, an upper slide groove and a lower slide groove for the RFID housing to slide are provided in the groove.

[0014] In one embodiment, the depth of the upper slide groove is twice the depth of the lower slide groove.

[0015] In one of the embodiments, the RFID housing is provided with silicone along the circumference.

[0016] In one embodiment, the driving mechanism includes an electric push rod; the electric push rod is installed in the spray tool, and the output end of the electric push rod is connected to the RFID shell to drive the RFID shell to cover or reveal the RFID chip tag.

[0017] Beneficial effects of the utility model:

The driving mechanism drives the RFID shell to cover or reveal the RFID electronic tag, so as to avoid the RFID electronic tag being covered with spraying materials, which causes the reader to be unable to read or error, thereby improving production quality and efficiency.

[0027] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0028] See also Figure 1 and Figure 2 In one embodiment, a brake disc spraying tool based on RFID includes: a spraying tool 1, an RFID chip tag 2, an RFID housing 5 and a driving mechanism 6.

[0029] In one embodiment, the spraying tool 1 includes a base 11, a rotating motor 12 and a support frame 13. The base 11 is slidably mounted on the spraying production line, and the rotating motor 12 is mounted on the base 11; the support frame 13 is mounted at the output end of the rotating motor 12, and is used to carry the brake disc 7. The rotating motor 12 drives the support frame 13 to rotate, and the brake disc 7 is sprayed in a rotating state, which is conducive to uniform spraying.

[0030] Specifically, the base 11 is a slider that slides along the conveyor chain of the spraying production line, so that the spraying tooling does not need to be moved manually, thereby improving production efficiency. The base 11 is made of plastic, and a metal balance block is provided at the bottom. The metal and the plastic do not form a loop, thereby avoiding the influence of the metal on the RFID antenna. The support frame 13 includes a support rod 131 and a support seat 132. The support rod 131 is installed at the output end of the rotating motor 12, and the support seat 132 is detachably inserted in the upper part of the support rod 131 for carrying the brake disc 7. Preferably, the support seat 132 is a conical structure, which can carry brake discs 7 with different inner diameters, thereby improving its application scenarios. The support seat 132 is provided with a plurality of ridges 133, and the ridges 133 are evenly spaced along the circumference of the support seat 132. With this structure, the brake disc 7 is placed on the ridges 133, the contact area is small, and there is a gap with the support seat 132, so that the brake disc 7 is easily removed from the support seat 132.

[0031] In one embodiment, an RFID chip tag 2 with the ability to write and read information multiple times is used in the prior art and is disposed on a base 11. Specifically, the RFID chip tag 2 includes an antenna, a memory, and a control system; the antenna and the memory are respectively connected to the control system by wires, and information data can be written and read multiple times in the memory.

[0032] In one embodiment, the spraying production line also includes a plurality of readers 3, a computer 4, a code reader 8, a plurality of sensors, a first mechanical arm 61 and a second mechanical arm 62. The first mechanical arm 61, the second mechanical arm 62, the sensor and the computer 4 are respectively installed on the spraying production line, the code reader 8 is installed on the second mechanical arm 62, and the reader 3 is installed on the first mechanical arm 61. The first mechanical arm 61 drives the reader 3 to approach or move away from the RFID electronic tag 2, and the RFID electronic tag 2 is connected to the reader 3 through a radio frequency signal. The second mechanical arm 62 drives the code reader 8 to approach or move away from the two-dimensional code on the brake disc 7. The code reader 8 and the reader 3 are connected to the computer 4 through a communication line, and the computer 4 processes the reader 3 to read or write relevant information from the RFID electronic tag 2, and processes the code reader 8 to read relevant information from the two-dimensional code. Sensor detection is used to detect whether the position of the brake disc 7 is in place.

[0033] When in use, after the sensor detects that the brake disc 7 has reached the designated position, the second mechanical arm 62 drives the code reader 8 to approach the two-dimensional code on the brake disc 7 and reads it; the first mechanical arm 61 drives the reader 3 to approach the RFID electronic tag 2 and reads it, so as to bind the two-dimensional code content with the RFID chip and temporarily store the information in the computer 4. When the brake disc 7 is at the unloading end after painting, after the sensor detects that the brake disc 7 has reached the designated position, the first mechanical arm 61 drives the reader 3 to approach the RFID electronic tag 2 and reads it, and feeds back the read content information to the computer 4. The computer 4 provides the required engraved two-dimensional code content to the laser marking machine and laser engraves it on the surface of the brake disc 7 after painting, so as to achieve the correspondence between the two-dimensional code content before and after painting.

[0034] In one embodiment, the RFID housing 5 is slidably disposed on the base 11. The base 11 is provided with a groove 14 matching the shape of the RFID chip tag 2 at one end facing the reader / writer 3, and the RFID chip tag 2 is installed in the groove 14. The groove 14 is provided with an upper slide groove 141 and a lower slide groove 142 for the RFID housing 5 to slide, so that the RFID housing 5 can slide smoothly. The material of the RFID housing 5 is plastic.

[0035] In order to enhance the sealing performance between the RFID housing 5 and the groove 14 , silicone is provided on the RFID housing 5 along the circumferential direction.

[0036] In one embodiment, the driving mechanism 6 is disposed in the working cavity of the base 11, and the output end of the driving mechanism 6 is connected to the RFID housing 5 to drive the RFID housing 5 to cover or reveal the RFID chip tag. Preferably, the driving mechanism 6 is an electric push rod.

[0037] When the first robotic arm 61 drives the reader / writer 3 to approach the RFID chip tag 2, the electric push rod drives the RFID shell 5 to move, so that the RFID shell 5 reveals the RFID chip tag 2, and the reader / writer 3 reads the content of the RFID chip tag 2; when the first robotic arm 61 drives the reader / writer 3 away from the RFID chip tag 2, the electric push rod drives the RFID shell 5 to move, and the RFID shell 5 covers the RFID chip tag 2.

[0038] When in use, after the brake disc 7 is processed, the relevant information is printed on the brake disc 7 in the form of a two-dimensional code. When the brake disc 7 is transferred to the coating process, the sensor detects that the brake disc 7 has reached the designated position, and the second mechanical arm 62 drives the code reader 8 to approach the two-dimensional code on the brake disc 7 for reading, and uploads the read information to the computer 4 for storage, and the first mechanical arm 61 drives the reader 3 to approach the RFID chip tag 2, and the electric push rod drives the RFID shell 5 to move, so that the RFID shell 5 reveals the RFID chip tag 2, and the reader 3 reads the RFID chip tag 2, and the read information is uploaded to the computer 4, and the computer 4 binds the two-dimensional code content with the RFID chip and temporarily stores it. After completion, the first mechanical arm 61 and the second mechanical arm 62 are reset, and the RFID shell 5 shields the RFID chip tag 2, and enters the spraying stage. Because the RFID shell 5 shields the RFID chip tag 2, the spraying material will not stick to the RFID chip tag 2, and thus will not affect the reading of the RFID chip tag 2 by the reader 3. When the brake disc 7 is at the unloading end after painting, the sensor detects that the brake disc 7 is in place, and the first mechanical arm 61 drives the reader 3 to approach the RFID chip tag 2, and the electric push rod drives the RFID shell 5 to move, so that the RFID shell 5 reveals the RFID chip tag 2, and the reader 3 reads the RFID chip tag 2, and transmits the read content information to the computer 4. The computer 4 provides the required engraved two-dimensional code content to the laser marking machine and laser engraves it on the surface of the brake disc 7 after painting, so that the two-dimensional code content before and after painting corresponds. After the RFID chip tag 2 is read, the chip content is cleared, and the first mechanical arm 61 is reset to perform the next cycle.

[0039] Beneficial effects of the utility model:

[0040] The above-mentioned RFID-based brake disc spraying tooling, by arranging the RFID electronic tag 2, the RFID shell 5 and the driving mechanism 6 on the disc spraying tooling, realizes that the contents of the two-dimensional code before and after painting correspond to each other, and the data is accurate. The driving mechanism 6 drives the RFID shell 5 to cover or reveal the RFID electronic tag 2, and the RFID shell 5 is provided with silicone along the circumference, which has good sealing performance, thereby preventing the RFID electronic tag 2 from being covered with spraying material, causing the reader 3 to be unable to read or error, thereby improving production quality and efficiency.
