Description

Technical Field

[0001] The utility model relates to the technical field of automobile production, and particularly relates to an automobile patch production detection device. Background Technique

[0002] SMT is an electronic assembly technology that mounts leadless or short-leaded chip components on the surface of a printed circuit board (PCB) or the surface of other substrates and is assembled by methods such as reflow soldering or dip soldering. In the automotive industry, SMT chip technology is widely used in the manufacturing of various automotive electronic products, such as automotive instrument panels, central control systems, navigators, ballasts, etc.; and in the process of automotive SMT chip processing, detection is an important link to ensure product quality.

[0003] The utility model patent with the authorization announcement number CN216432863U discloses a patch detection device for automotive technical services. The patch detection device for automotive technical services includes a conveyor belt assembly and a fixing frame. The fixing frame includes two support plates and a top plate. The upper ends of the two support plates are connected to the top plate. The conveyor belt assembly is arranged between the two support plates. A fixing device is connected to the top plate. The fixing device is connected with a positioning camera. Each support plate is connected with an infrared detection device. A warning lamp and a controller are connected to the right support plate. A base is fixedly connected to the conveyor belt assembly. A first stepping motor is fixedly connected to the base. A rotating column is connected to the first stepping motor. A carrier plate is connected to the free end of the rotating column. The positioning camera, the infrared detection device, the warning lamp and the first stepping motor are all connected to the controller. The infrared detection device is used to detect the patches on the carrier plate. Through the above settings, according to the comparison between the detection results of the infrared detection device and the standard data, the position of the unqualified components relative to the circuit board is displayed on the screen. The staff can analyze and determine the unqualified components through this imaging result and make marks. When remanufacturing, only the corresponding components need to be replaced, saving the time consumed in remanufacturing unqualified patches.

[0004] Although the patch detection device for automotive technical services is beneficial to display the position of the unqualified components relative to the circuit board, there are still the following problems in the actual use of this device: Specifically, during the manufacturing process, patches are extremely likely to be contaminated with dust and other tiny impurities due to factors such as electrostatic adsorption and environmental particles. Such attachments not only stain the appearance of the patches, but also they can obscure the key features of the patches and become "blind spots" in the subsequent detection process, directly threatening the accuracy and reliability of the detection results. However, this device does not clean the patches and directly conducts detection. Therefore, it may be unable to accurately capture the true state of the patches due to blocked vision, and it is difficult to ensure the accuracy of the detection results. In view of this, we propose an automobile patch production detection device. Summary of the Utility Model

[0030] This embodiment provides a technical solution:

[0031] Please refer to Figures 1-7 As shown, an automotive SMT patch production and detection device includes a base 1. Two side plates 10 are installed on the top of the base 1. Two idler rollers 14 are rotatably installed between the two side plates 10. A conveyor belt 15 for conveying automotive SMT patches is sleeved on the two idler rollers 14. A first motor 11 for driving the idler rollers 14 to rotate is installed on the outer wall of the right side plate 10. A top plate 12 is fixed at the front side between the two side plates 10. A camera 13 for scanning automotive SMT patches is installed at the bottom of the top plate 12. Mounting grooves 101 are opened at the rear side of the top of the side plates 10. A cleaning section 2 for cleaning the surface of automotive SMT patches is installed between the two mounting grooves 101. The cleaning section 2 includes a fixed plate 25 inserted into the mounting groove 101. Two roller bodies 26 are rotatably installed between the two fixed plates 25. Brush bristles 260 are installed on the outer wall of the roller body 26. The end of the roller body 26 passes through the fixed plate 25 and is coaxially key-connected to a gear 27. Adjacent two gears 27 are meshed with each other. A second motor 29 for driving the roller body 26 to rotate is installed on the right fixed plate 25. A hollow box body 20 is fixed at the top end between the two fixed plates 25. A plurality of dust suction holes 201 are opened at the bottom of the box body 20. Shells 21 are installed at both ends of the box body 20. A filter chamber 210 communicating with the box body 20 is opened at the top of the shell 21. A plurality of dust filter nets 22 are installed in the filter chamber 210. A detachable cover plate 28 is installed at the top of the filter chamber 210. A fan 23 communicating with the filter chamber 210 is installed on the outer wall of the shell 21.

[0032] Furthermore, slots 211 are formed in the outer walls of the housing 21. A plurality of connecting grooves 212 are formed between the slots 211 and the filtering cavity 210, and the connecting grooves 212 are located at one side of the bottom of the dust filter net 22. Tray boxes 24 are inserted into the slots 211. A plurality of collecting grooves 240 are formed in the tops of the tray boxes 24, and the collecting grooves 240 communicate with the corresponding connecting grooves 212. This design facilitates the collection of the dust falling from the dust filter net 22 through the plurality of collecting grooves 240.

[0033] In this embodiment, an outer plate 241 is fixed to the outer wall of the tray box 24. Two insertion blocks 242 are fixed to the bottom end of one side wall of the outer plate 241. Two insertion buckles 213 are fixed to the bottom edge of the housing 21. A fixing bolt 214 is threadedly connected to the bottom of the insertion buckle 213. The insertion block 242 is inserted into the opening of the insertion buckle 213, and the fixing bolt 214 passes through the insertion block 242. This design facilitates the disassembly, assembly and fixation of the outer plate 241 and the tray box 24. At the same time, the bolt fixation method facilitates the disassembly of the outer plate 241 and the tray box 24, thereby facilitating the cleaning of dust.

[0034] In this embodiment, the cross-sectional shape of the dust suction holes 201 is circular, and the plurality of dust suction holes 201 are arranged in a matrix. The arrangement of the plurality of dust suction holes 201 has the advantage of comprehensive coverage, which is conducive to quickly adsorbing dust and the like swept from the automotive patch.

[0035] In this embodiment, mounting blocks 202 are fixed to the bottom ends of the outer walls on both sides of the box body 20, and the mounting blocks 202 are fixedly connected to the side plate 10 by bolts. This design facilitates the stable installation of the cleaning part 2 and the side plate 10, and ensures the reliable installation of the cleaning part 2.

[0036] In this embodiment, limiting strips are installed on both side walls of the fixing plate 25. Limiting grooves 102 are formed in both side walls of the installation groove 101, and the limiting strips are inserted into the limiting grooves 102. The arrangement of the limiting strips and the limiting grooves 102 increases the installation stability and reliability between the fixing plate 25 and the side plate 10.

[0037] In this embodiment, the collecting groove 240 is located directly above the corresponding connecting groove 212, and the width of the collecting groove 240 is greater than the width of the connecting groove 212. This design is conducive to collecting dust and the like falling at the connecting groove 212 through the collecting groove 240.

[0038] In this embodiment, the top plate 12 is fixedly connected to the side plate 10 by bolts, and the camera 13 is fixedly connected to the top plate 12 by bolts.

[0039] It should be added that in this embodiment, the cover plate 28 is fixedly connected to the housing 21 by bolts. The bolt fixing method not only makes the installation of the cover plate 28 firm and stable, but also facilitates the disassembly of the cover plate 28, thereby facilitating the opening of the filter chamber 210 to clean the dust filter net 22.

[0040] It should be noted that the first motor 11 and the second motor 29 involved in this embodiment are existing conventional technologies and will not be elaborated here.

[0041] During specific use, the user first turns on the power supply of the first motor 11. The first motor 11 starts to work. The output shaft of the first motor 11 rotates to drive the idler roller 14 to rotate. The idler roller 14 drives the conveyor belt 15 to move. The conveyor belt 15 simultaneously drives the automotive SMT patch to move horizontally. At the same time, the user turns on the power supplies of the second motor 29 and the blower 23. The second motor 29 and the blower 23 start to work. The output shaft of the second motor 29 rotates to drive the roller body 26 and the gear 27 to rotate. Since the two gears 27 are meshed, the two roller bodies 26 rotate synchronously relative to each other. The roller body 26 simultaneously drives the brush bristles 260 to rotate. When the automotive SMT patch passes below the roller body 26, the brush bristles 260 simultaneously clean the surface of the automotive SMT patch. At the same time, the generated dust is sucked into the box body 20 through a plurality of dust suction holes 201 and directly enters the filter chamber 210. The dust simultaneously passes through a plurality of dust filter nets 22. The dust is intercepted and filtered by the dust filter nets 22. The filtered gas is discharged through the blower 23. The dust intercepted on the dust filter nets 22 falls under the action of gravity and drops into the collection tank 240 through the connecting groove 212. As the conveyor belt 15 continues to move, the conveyor belt 15 drives the automotive SMT patch to move out from below the roller body 26. At this time, the surface of the automotive SMT patch is cleaned. When the automotive SMT patch passes below the camera 13, the camera 13 scans and takes pictures of the automotive SMT patch and conducts inspections.
