[0034] The electronics industry is an important pillar of today's economic development, and testing equipment is an important tool for testing electronic components. It can effectively detect the performance, quality and parameters of electronic products in order to verify the reliability of the products.
[0035] Electronic components are the basic components of circuit boards, such as transistors, resistors, capacitors, etc., which realize various functions of electronic devices through different characteristics and functions. Circuit board test equipment ensures the normal operation and reliability of circuit boards by testing the electrical performance, connectivity, etc. between various components and connections on the circuit board. These devices play a vital role in the field of electronic manufacturing and maintenance.
[0036] During the production and manufacturing process of circuit boards, it is necessary to scan the identification codes on the circuit boards to track the production process, prevent incorrect assembly, and improve production efficiency. Existing scanning devices for circuit boards can only perform scanning tests on circuit boards of the same type, and cannot test circuit boards of different models and specifications, and have low wide applicability.
[0037] In order to solve the above problems, the utility model proposes an automatic code scanning device, which aims to provide an automatic code scanning device with wide applicability that can meet the testing requirements of circuit boards of different models and specifications. Figures 1 to 4 The present invention is a schematic diagram of the structure of an embodiment of the automatic code scanning device provided by the present invention.
[0038] Please refer to Figures 1 to 4 The utility model proposes an automatic code scanning device 1000, including a test bench 1, a pressing structure and a split test frame 3, the pressing mechanism 2 is arranged on the test bench 1 and is provided with a driving end 241 facing the bottom plate 31, the split test frame 3 includes a bottom plate 31 and a movable plate 32 movably arranged on the bottom plate 31, the bottom plate 31 is provided with a fixing seat 312, the fixing seat 312 is detachably arranged on the bottom plate 31 and is used to position the product to be tested, the movable plate 32 is provided with a code scanning component 33, the code scanning component 33 is provided with a scanning end facing the bottom plate 31, the driving end 241 is connected to the movable plate 32 and
[0039] It is used to drive the movable plate 32 to drive the scanning end to approach or move away from the product to be tested to scan the code of the product to be tested.
[0040] In the technical solution of the utility model, an automatic code scanning device 1000 and a test device are proposed, wherein the automatic code scanning device 1000 comprises a test bench 1, a pressing mechanism 2 and a split test frame 3, the pressing mechanism 2 is arranged on the test bench 1, the split test frame 3 is detachably arranged on the test bench 1, the split test frame 3 comprises a bottom plate 31 and a movable plate 32, the bottom plate 31 is used to place the product to be tested, the movable plate 32 is located above the bottom plate 31, and the side of the movable plate 32 facing away from the bottom plate 31 is connected to the driving end 241 of the pressing mechanism 2. During the code scanning process, the product to be tested is placed on the bottom plate 31, and the pressing mechanism 2 drives the movable plate 32 to move. The code scanning component 33 on the movable plate 32 starts to move close to the product to be tested on the bottom plate 31. When the distance is sufficient for the code scanning component 33 to scan the identification code on the product to be tested, the code scanning component 33 scans and collects relevant information of the product to be tested, and then the pressing mechanism 2 drives the movable plate 32 to rise, takes out the scanned product, and repeats the above operation. The equipment adopts a split design, and the fixed seat 312 on the split test frame 3 can be disassembled from the test bench 1 to replace the fixed seat 312 of other different products, thereby realizing the code scanning test of circuit boards of different models and specifications, improving the wide applicability of the equipment, and thus achieving cost reduction.
[0041] It should be noted that the fixing seat 312 can be fixed by screwing or by clamping, and the present invention does not limit this. In one embodiment of the present invention, the fixing seat 312 is formed with a plurality of threaded holes, and correspondingly, the base plate 31 is also provided with matching threaded holes, and the two are fixed by bolts. The advantage of fixing the detachable fixing seat 312 and the base plate 31 by bolts is that it provides a flexible, stable and easy-to-maintain connection method. Bolt fixing can be quickly installed and disassembled, which is convenient for replacing the fixing seat 312. At the same time, the bolt connection has a high load-bearing capacity and stability, ensuring safety and reliability during the test process. In addition, the detachable fixing seat 312 and the base plate 31 help to reduce maintenance costs and downtime, and improve the overall use efficiency of the equipment.
[0042] Since the device is applied to the scanning procedure of the circuit board, in order to prevent the circuit board from being placed unstably, which makes it difficult for the scanning component 33 to focus and scan, the fixing seat 312 is formed with a contoured groove 312a that matches the shape of the circuit board to be tested. For details, please refer to Figure 4 The fixing seat 312 is processed by CNC to form a contoured groove 312a according to the external contour of the product. The product is placed in the contoured groove 312a, and its peripheral wall fits well with the inner wall of the contoured groove 312a to ensure the stable placement of the product. The replaceable fixing seat 312 only needs to process the required circuit board shape contour on different seats to realize the placement of different types of circuit boards, thereby meeting the test scanning requirements of different circuit boards.
[0043] Before scanning the code, the control components and data collection components in the electrical box assembly 11 need to be electrically connected to the test components on the split test stand 3. In the technical solution of the present utility model, a quick connector is used to achieve quick plug-in. An installation cavity is formed in the electrical box assembly 11 for internal wiring. Considering that the various electronic components in the electrical box assembly 11 will generate electromagnetic interference to the circuit board when working, and the bottom plate 31 is directly connected to the installation cavity, the bottom of the circuit board to be tested is exposed, which is easy to cause scratches. In order to solve the above two problems, the split test stand 3 is also provided with an isolation plate 34. For details, please refer to Figure 4 The isolation plate 34 is arranged below the bottom plate 31 and is spaced apart from the bottom plate 31 by one end. When the split test frame 3 is installed on the test bench 1, the isolation plate 34 is located in the installation cavity as a whole, and can form a barrier between the electronic components and the circuit board to be tested, thereby producing a certain electromagnetic shielding effect. On the other hand, it also blocks the wiring harness, components and the circuit board to be tested in the installation cavity, avoiding the risk of scratches on the circuit board to be tested.
[0044] Furthermore, the isolation plate 34 is connected to the side of the base plate 31 facing away from the movable plate 32 through the guide block 12. The outer wall of the guide block 12 abuts against the inner wall of the installation frame to form a limit. The guide block 12 can realize a guiding effect when the split test frame 3 is installed. The two ends of the guide block 12 are respectively fixed to the base plate 31 and the isolation plate 34 by screwing. In order to realize the reliable placement of the split test frame 3, the size of the base plate 31 is slightly larger than the size of the installation frame, and the size of the isolation plate 34 is slightly smaller than the size of the installation frame. This arrangement allows the isolation plate 34 to be easily placed in the installation cavity, and the base plate 31 is overlapped on the four sides of the installation frame to achieve stable placement.
[0045] After the split test frame 3 is placed and fixed in place, the driving end 241 of the pressing mechanism 2 needs to be connected to the movable plate 32 of the split test frame 3, so that the movable plate 32 can be driven to reciprocate up and down under the movement of the driving end 241. During the reciprocating up and down movement of the movable plate 32, in order to ensure that the position of the code scanning component 33 is aligned with the position of the identification code on the circuit board to be tested, and to ensure that the movable plate 32 can run along a predetermined route, four guide columns 311 are provided on one side of the bottom plate 31 facing the movable plate 32. For details, please refer to Figure 1 and Figure 4 Four guide posts 311 are respectively arranged at the four corners of the movable plate 32, and the movable plate 32 is movably passed through the four guide posts 311. The four guide posts 311 determine a unique movement route. Furthermore, a handle 313 is provided at one end of each two adjacent guide posts 311 away from the bottom plate 31. When the split test frame 3 is disassembled, the staff can hold the two upper handles 313 for easy disassembly and transfer. Furthermore, the handle 313 can also realize a limit stop function for the movable plate 32.
[0046] In order to upload the test data to the data center in real time, and then analyze the data to realize intelligent production of the product, the electrical box component 11 is provided with an installation cavity with an opening, and a data transmission device (not marked in the figure) is provided in the installation cavity. The data transmission device is electrically connected to the code scanning component 33. When the scanning end of the code scanning component 33 scans the product identification code, the relevant information of the product will be uploaded to the data center, and the data center can realize real-time monitoring and data management of the product production process. The benefits of this approach include: improving production efficiency, reducing human errors, facilitating product quality traceability, realizing information sharing, and providing data support for decision-making. At the same time, the cloud data center can store a large amount of data, facilitate data mining and analysis, and provide valuable information for enterprises.
[0047] In order to prevent the movable plate 32 from exceeding the stroke and crushing the circuit board product to be tested during the downward pressing process, the movable plate 32 is provided with a plurality of probes 321 toward the bottom plate 31. For details, please refer to Figure 4 When the cylinder drives the movable plate 32 to press downward, the probe 321 will abut against the blank area of the circuit board, thereby limiting the movement of the movable plate 32 and preventing the movable plate 32 from further pressing down and causing damage to the circuit board. Furthermore, the probe 321 is made of Saigang, which has excellent mechanical properties such as high strength, wear resistance, impact resistance and heat resistance, as well as good transparency and electrical insulation. A test port 322 is provided on the movable plate 32, and the scanning end of the code scanning component 33 is arranged toward the test port 322 and can scan the product below the test port through the test port 322.
[0048] To adjust the driving member 24, the pressing mechanism 2 includes a control assembly 4. For details, please refer to Figure 3 The control assembly 4 includes a solenoid valve 41 and a pressure regulating valve 42. The solenoid valve 41 is mainly used to control the air intake and exhaust of the cylinder, thereby controlling the extension and retraction of the cylinder. When the solenoid valve 41 is energized, it will open, allowing compressed air to enter one side of the cylinder and push the piston rod of the cylinder to extend; when the solenoid valve 41 is de-energized, it will close, preventing air from entering and allowing the air in the cylinder to be discharged, causing the piston rod to retract. The function of the solenoid valve 41 is to respond quickly and achieve precise control of the cylinder. The main function of the pressure regulating valve 42 is to adjust the air pressure when the cylinder is working and ensure that the cylinder works at a set pressure. The pressure regulating valve 42 can reduce the pressure of the high-pressure gas source and stabilize it at a fixed value, which can be adjusted according to the working requirements of the cylinder. The pressure regulating valve 42 can protect the cylinder from damage caused by excessive pressure and ensure the smooth and reliable operation of the cylinder.
[0049] The utility model also proposes a testing device, which includes an automatic code scanning device 1000. The specific structure of the automatic code scanning device 1000 refers to the above embodiment. Since the testing device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
[0050] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
