Description

Technical Field

[0001] This invention belongs to the field of brake component processing technology, specifically relating to an automatic QR code spraying equipment for brake components. Background Technology

[0002] Brake components are an important part of the braking system. Their main function is to slow down or stop the wheels through friction, thus bringing the vehicle to a stop. The following are some of the main components of brake components and their functions: Brake pads, also known as brake shoes, are generally composed of a steel plate, an adhesive heat insulation layer, and friction blocks; Brake discs are another key component of the braking system. They interact with the brake pads to generate friction, which slows down or stops the wheels.

[0003] In addition to standard processing steps, brake component manufacturing sometimes requires the addition of a QR code spraying process for traceability. Brake components typically include some defective parts, such as those with unreadable QR codes. Therefore, during processing, qualified and defective components must be separated. After processing, the brake components gradually accumulate on one side of the processing unit. This requires providing ample space for stacking, as previously stacked components can hinder the transfer of subsequent components. Furthermore, to prevent impacts during packaging that could affect the brake components' appearance, operators must handle each component carefully, impacting the unloading schedule and necessitating additional personnel to handle both loading and unloading operations. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide an automatic QR code spraying device for brake parts, so as to solve the problems mentioned in the background art.

The position detection component is also used to determine whether each second positioning mold has entered the loading area by emitting a laser so that the positioning component can fix it.

[0010] Preferably, the processing device further includes a pre-treatment unit installed on the support, which is located between the feeding unit and the coding unit and is used to heat the brake components.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 17 As shown, this embodiment of the invention provides an automatic QR code spraying device for brake components, comprising: The processing device 100 is used to complete the operation of spraying ink onto brake components to form QR codes, and also to classify and transfer the processed brake components. The receiving device 200 is used to receive brake parts that have been sorted and transferred by the processing device 100; The receiving device 200 includes a conveying part 210, a collecting part 220, and a retractable guiding part 230. The conveying part 210 is disposed on one side of the processing device 100 and is used to convey qualified brake components. The guiding part 230 is rotatably connected to the processing device 100 and is used to guide unqualified brake components into the collecting part 220. The collecting part 220 is used to collect unqualified brake components. The collection unit 220 includes multiple sealing sidewalls 221, a bottom wall 222, and an adjusting sidewall 223. One of the sealing sidewalls 221 is connected to any of the other sealing sidewalls 221. The bottom wall 222 is rotatably connected to any one of the sealing sidewalls 221. The adjusting sidewall 223 is rotatably connected to the bottom wall 222 and is used to bond with the guide unit 230. The bottom wall 222, the adjusting sidewall 223, and each sealing sidewall 221 enclose a collection cavity with an adjustable spatial area and an upward-facing opening.

[0022] The processing device 100 needs to complete the task of spraying ink onto the brake components to form QR codes. Based on this, in some cases, the processing device 100 may include existing automatic spraying equipment. In addition, the processing device 100 also needs to classify and transfer the processed brake components. Based on this, the processing device 100 may include existing robotic arms. The above description of the processing device 100 is only for the purpose of helping to understand the processing device 100, and the specific structure of the processing device 100 is not limited here.

[0023] The internal structure of the receiving device 200 is illustrated here as follows: the conveying section 210 can be configured as a conveyor for conveying qualified brake components to the remaining processing areas; the guiding section 230 can be configured as a telescopic plate with adjustable length and rotational movement, thereby adjusting the downward speed of the brake components; the collecting section 220 can be regarded as a box-shaped structure with a cuboid structure in some cases.

[0024] It should be further explained that, in addition to the guide part 230 being tilted, the bottom wall 222 and the adjusting side wall 223 are also tilted, and the adjusting side wall 223 can be bonded to the guide part 230 to support and fix each other. When the guide part 230, the bottom wall 222 and the adjusting side wall 223 are all tilted, the brake component can be slowly guided into the collection cavity, and while the brake component is dispersed in the collection cavity, a strong impact between the brake components is avoided, thereby preventing the appearance of the brake component from being affected during the unloading process.

[0025] When the brake component enters the collection chamber, it can move in accordance with the adjusting side wall 223 and bottom wall 222, thus avoiding impact on the bottom wall 222 of the collection chamber or the brake component inside the collection chamber due to its falling motion. At this point, the unloading process is completed by the receiving device 200. The receiving device 200 can transfer the brake component in time to avoid affecting the unloading progress. At the same time, it can avoid the need to add operators to perform the loading and unloading operations separately.

[0026] By setting up the receiving device 200, the gradual accumulation of brake components can be avoided, thereby avoiding the need to provide a large space for the brake components and preventing the processed brake components from obstructing the processing device 100 from transferring subsequent brake components.

[0027] It should be noted that, in order to further reduce the impact on the appearance of the brake components, some materials can be used to make the guide part 230, the bottom wall 222 and the adjustment side wall 223, such as high molecular materials such as polytetrafluoroethylene, and metal-based composite materials such as aluminum alloy containing lubricating additives.

[0028] It should also be noted that the bonding method in this invention can be accomplished in various forms, such as by using Velcro, and no specific limitation is made here.

[0029] In this embodiment, the processing apparatus 100 includes a support 110, a control unit 120, a loading unit 130, a unloading unit 140, a coding unit 150, a circular conveying unit 160, and a detection unit 170. At least a portion of the control unit 120 is mounted on the support 110 and is used to control the operation of the loading unit 130, the unloading unit 140, the coding unit 150, and the circular conveying unit 160. The loading unit 130 is mounted on the support 110 and is used to transfer the brake component to the circular conveying unit. 160, the unloading unit 140 is mounted on the support part 110 and is used to classify and transfer the brake parts to the conveying part 210 and the guide part 230; the inkjet printing unit 150 is mounted on the support part 110 and is used to spray ink onto the surface of the brake parts; the annular conveying unit 160 is mounted on the support part 110 and is used to convey the brake parts along the annular line; the detection unit 170 is mounted on the support part 110 and is used to detect the QR code on the brake parts; the detection unit 170 is located on the side of the inkjet printing unit 150 away from the unloading unit 130. The loading unit 130 and the unloading unit 140 are respectively placed on both sides of the annular conveying unit 160 in a symmetrical distribution. The conveying unit 210 is located on one side of the unloading unit 140, and the guide unit 230 is rotatably connected to the unloading unit 140.

[0030] The processing apparatus 100 has been described in an expanded manner above. In this embodiment, the processing apparatus 100 has been expanded in terms of function and thus in terms of structure.

[0031] In the actual processing, the support part 110 is an integral support structure, and the control unit 120 is the core control structure. Initially, the loading unit 130 transfers one or more brake parts to the ring conveying unit 160. During the process of the ring conveying unit 160 transferring the brake parts along the ring line, the inkjet printing unit 150 first sprays ink onto the brake parts to form a QR code. Then, the detection unit 170 detects the QR code on the brake parts, and then the unloading unit 140 removes the brake parts.

[0032] The structure of the support part 110 can be adjusted according to the actual situation, and no specific limitations are made here.

[0033] The control unit 120 is used to control the operation of the feeding unit 130, the unloading unit 140, the inkjet printing unit 150, and the annular conveying unit 160. The control method can be an electrical connection. It should be emphasized that all electric structures, drive structures, and sensing structures in this invention can be electrically connected to the control unit 120 and be uniformly coordinated by it. For example, some units may include sensors. The sensors are sensing structures and can be controlled by the control unit 120 to operate and transmit the detected information to the control unit 120 in a timely manner.

[0034] Optionally, the control unit 120 includes an industrial control computer group for controlling the circular conveyor unit 160 to run along the loop, an inkjet printer control console group for controlling the operation of the inkjet printer unit 150, and an electrical control box group for controlling the operation of the feeding unit 130. The electrical control box group includes a display screen for displaying processing information, such as displaying the detection information of the QR codes on each brake component.

[0035] Optionally, the coding unit 150 includes an inkjet printer and an inkjet printer mounting frame, with the inkjet printer mounted on the support unit 110 via the mounting frame. During operation, the coding unit 150 remains relatively stationary relative to the support unit 110. During coding, the brake is in motion while the coding unit 150 remains stationary, preventing repeated starts and stops of the ring conveyor unit 160 from affecting the processing progress. It should be noted that the inkjet printer can create QR codes on objects using inkjet technology. This primarily relies on inkjet printing technology, which sprays ink onto the surface of an object to form the desired image and text, including QR codes. When generating a QR code, the inkjet printer converts the data information into binary code and maps these codes onto the black and white modules of the QR code using a specific algorithm. Thus, when a scanning device scans the QR code on an object, it can parse the encoded information.

[0036] Optionally, the detection unit 170 includes at least one set of barcode scanners, which includes a barcode scanner and a barcode scanner support frame. The barcode scanner is connected to the support part 110 through the barcode scanner support frame. The barcode scanner can detect whether there are duplicate codes, garbled codes, or unreadable codes on the QR code on the brake component by scanning it. The detection unit 170 can transmit the detection information to the control unit 120 so that the control unit 120 can control the unloading unit 140 to separate and place qualified brake components from unqualified brake components.

[0037] Optionally, the annular conveyor unit 160 includes an annular conveyor belt. Compared to a linear conveyor unit, the annular conveyor unit 160 can reduce the space required for the processing device 100. In addition, due to the installation of the receiving device 200, it is not necessary to install a linear conveyor unit so that the operator can observe the conveying status of the brake components and pack the brake components in a timely manner, thereby reducing labor costs.

[0038] In this embodiment, the processing device 100 further includes a positioning unit, which includes a support platform 181 connected to the feeding unit 130, a plurality of first positioning molds 182 connected to the support platform 181, and a plurality of second positioning molds 183 installed on the annular conveying unit 160. The number of second positioning molds 183 is not less than the number of first positioning molds 182.

[0039] With the positioning unit in place, during loading, the operator places the brake components one by one onto the first positioning mold 182, and then the loading unit 130 transfers the brake components to the second positioning mold 183.

[0040] By setting the second positioning mold 183, the problem that the brake component of the annular conveying unit 160 is prone to movement when running at high speed is solved, which makes it easier to increase the running speed of the annular conveying unit 160 while avoiding the formation of QR codes in areas outside the predetermined area on the brake component.

[0041] Compared to the method where the operator places the brake component onto the first positioning mold 182, the method where the feeding unit 130 cooperates with the operator to transfer the brake component has the following effects: before the second positioning mold 183 moves into the loading area, the operator can place the brake component onto the first positioning mold 182, and the feeding unit 130 is a mechanical feeding unit, whose feeding speed can be kept stable, which is beneficial for the control unit 120 to perform overall control of the processing process.

[0042] In this embodiment, the positioning unit further includes a positioning component 184 installed on the support 110 and a mating component 185 installed on each of the second positioning molds 183 and corresponding to the positioning component 184. The positioning component 184 is used to prevent the second positioning molds 183 from moving during the feeding process of the feeding unit 130 by fixing the mating component 185.

[0043] Optionally, both the first positioning mold 182 and the second positioning mold 183 have curved surfaces. Taking the first positioning mold 182 as an example, when the brake component is placed in contact with the first positioning mold 182, it is not necessary to align the brake component with the predetermined area. The curved surface can guide the brake component into the predetermined area, reducing the difficulty of placing the brake component.

[0044] Optionally, the mating part 185 is configured as a block structure with a mating groove.

[0045] Optionally, the positioning assembly 184 includes a fixing plate mounted on the support portion 110, a cylinder connected to the fixing plate, and a locking plate connected to the cylinder. When the cylinder drives the locking plate to engage in the mating groove, the second positioning mold 183 cannot move.

[0046] The positioning component 184 allows the feeding component to be omitted in some cases, such as when the feeding component is damaged. In this case, the operator can directly move the brake to the second positioning mold 183. Before that, the positioning component 184 can restrict the movement of the second positioning mold 183 to avoid the operator falling to one side and getting injured due to the sudden start of the annular conveyor unit 160.

[0047] It should be noted that, depending on the sensor settings, the ring conveyor unit 160 may have multiple operating modes. In one operating mode, the ring conveyor unit 160 runs at a preset operating speed and stops within a predetermined time period. In other cases, the ring conveyor unit 160 only continues to run when the positioning component 184 releases the positioning of the mating component 185.

[0048] In this embodiment, the positioning unit further includes a position detection component 186 installed on the support 110. The position detection component 186 is used to determine whether the brake component is installed in a predetermined area on the second positioning mold 183 by generating a laser. The position detection component 186 is also used to determine whether each second positioning mold 183 has entered the loading area by generating a laser so that the positioning component 184 can fix it.

[0049] Optionally, the position detection assembly 186 includes two symmetrically distributed position detection mechanisms. Each position detection mechanism includes a support frame mounted on the support part 110, a height detection sensor group connected to the support frame, and a position detection sensor group connected to the support frame. The height detection sensor group is used to determine whether the brake component is installed in a predetermined area on the second positioning mold 183 by emitting a laser. The position detection sensor group is used to determine whether each second positioning mold 183 has entered the loading area by emitting a laser so that the positioning assembly 184 can fix it.

[0050] It should be further explained that in some cases, when the inkjet unit 150 is spraying paint on the brake component, the distance between the two is very small, and the position detection component 186 can detect whether the brake component is installed in a predetermined area on the second positioning mold 183 to avoid the brake component being at a height higher than the predetermined height and touching the inkjet unit 150.

[0051] In this embodiment, the processing device 100 further includes a pre-processing unit 190 installed on the support part 110. The pre-processing unit 190 is disposed between the feeding unit 130 and the coding unit 150 and is used to heat the brake component.

[0052] Optionally, the pretreatment unit 190 includes a preheating lamp support frame mounted on the support part 110 and a preheating lamp connected to the preheating lamp support frame.

[0053] The pre-processing unit 190 processes the brake component before the coding unit 150. By heating the brake component, the pre-processing unit can improve the adhesion of ink to the surface of the brake component. Specifically, preheating can accelerate the molecular movement on the surface of the brake component, allowing ink molecules to better penetrate the surface of the brake component, thereby enhancing the adhesion of the ink. The preheating process helps to reduce the tension between the ink and the surface of the brake component, making it easier for the ink to wet the surface of the brake component and bond with it tightly. In addition, preheating can also accelerate the drying process of the ink, further consolidating the adhesion of the ink on the brake component.

[0054] By setting the pre-processing unit 190, the QR code spraying effect can be guaranteed while increasing the running speed of the annular conveying unit 160. Specifically, preheating can increase the temperature of the brake component surface, making it easier for the ink to spread and adhere when it comes into contact with the brake component. This helps to reduce the time required for the ink to flow on the brake component and form a QR code. Therefore, the running speed of the annular conveying unit 160 can be moderately increased while maintaining ink adhesion.

[0055] The pre-processing unit 190 can also reduce the total amount of scattered ink to a certain extent, as follows: During the process of the ink being ejected from the inkjet head to form a QR code on the brake component, some ink may be scattered outside the brake component. Preheating the brake component can increase the surface temperature of the brake component, making it easier for the ink to dry and adhere when it comes into contact with the brake component. When the ink comes into contact with the brake component at a higher temperature, its fluidity may be reduced, reducing the possibility of the ink being scattered outside the brake component due to flow.

[0056] In this embodiment, the processing device 100 also includes a plurality of curing units 101 installed on the support 110 and distributed in parallel, and each curing unit 101 is placed between the inkjet printing unit 150 and the detection unit 170.

[0057] Optionally, the curing unit 101 includes a curing lamp and a curing lamp support frame connected to the curing lamp and the support part 110.

[0058] Before the brake component is inspected by the inspection unit 170, the ink on it needs to be cured by the curing unit 101. The effect is as follows: the curing lamp, such as the UV curing lamp, can cause the photosensitive agent in the ink to undergo a chemical reaction by emitting ultraviolet light, so that the ink is cured quickly, making the QR code clearer, more stable, and less prone to wear or blurring.

[0059] It should be noted that, due to the setup of the pretreatment unit 190, the number of curing units 101 required can be reduced by keeping the annular conveyor unit 160 in operation during the time periods other than the loading and unloading processes, thereby shortening the length of the production line required to process brake parts.

[0060] In this embodiment, the feeding unit 130 includes a feeding frame 131 mounted on the support part 110, a moving mechanism 132 connected to the feeding frame 131, and a plurality of suction cup mechanisms 133 connected to the moving mechanism 132. The moving mechanism 132 is used to drive the suction cup mechanism 133 to move in the vertical and horizontal directions, and the suction cup mechanism 133 is used to drive the brake component to move by negative pressure adsorption.

[0061] Optionally, the feeding unit 130 also includes a plurality of placement sensors installed on the support 110. The placement sensors are used to detect whether a brake component is placed inside the first positioning mold 182 in order to determine whether the corresponding suction cup mechanism 133 is working.

[0062] It should be noted that, unless otherwise specified, the structure connected to the feeding unit 130 is considered to be connected to the feeding frame 131.

[0063] Optionally, the moving mechanism 132 is used to drive the suction cup mechanism 133 to move in the vertical and horizontal directions. Here, the moving mechanism 132 can be configured to consist of a vertically arranged electric slide and a horizontally arranged electric slide.

[0064] The suction cup mechanism 133 is used to move the brake component by means of negative pressure adsorption. To facilitate understanding of how the suction cup mechanism 133 works, a simplified combination structure is given here for explanation, as follows: The suction cup mechanism 133 includes a suction cup, a vacuum pump, a connecting pipe, and a fixing bracket. When it is necessary to move the brake component, the suction cup is first tightly attached to the surface of the brake component. Then, the vacuum pump is started to generate negative pressure and the gas inside the suction cup is discharged through the connecting pipe. Due to the negative pressure, an adsorption force is formed between the suction cup and the surface of the brake component, so that the brake component is firmly adsorbed on the suction cup. The fixing bracket is used to fix the suction cup and the connecting pipe.

[0065] In this embodiment, the feeding unit 130 and the unloading unit 140 have the same structure.

[0066] The structure of the unloading unit 140 can be referenced from the structure of the loading unit 130.

[0067] It should be noted that in some cases, the loading and unloading operations can be completed by the loading unit 130 alone, thereby reducing the cost of mechanical structure investment when there are many first positioning molds 182.

[0068] In this embodiment, a plurality of cover members 1 are rotatably connected to the support part 110, and each cover member 1 can cooperate to cover part of the structure inside the processing device 100 in a certain direction.

[0069] The cover 1 protects the detection unit 170, curing unit 101 and other structures.

[0070] Optionally, the cover 1 is made of tempered glass.
