[0002] Currently, hardware comparison is a new product developed to meet the hardware reliability requirements of power equipment, driven by advancements in power technology. Therefore, there are few tooling solutions specifically designed for this purpose on the market. Firstly, the variety and specifications of hardware are numerous, making it too costly for users to develop custom-designed tooling. Secondly, for ease and speed in replacing different products, there is a preference for tooling that can compare multiple hardware specifications, eliminating the need for repeated adjustments to the drive belt spacing, reducing the workload of product replacement, and improving efficiency. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a hardware comparison and compatibility fixture for power metering equipment. The PCB hardware board to be tested is fixed inside the work tray using a fixing mechanism.

[0020] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.
[0021] Combination Figure 1 , Figure 2 and Figure 3 As shown, a hardware comparison and compatibility fixture for an electricity metering device includes a fixture tray 1 for placing PCB hardware boards. The fixture tray 1 is conveyed by a conveyor belt 2. A camera 5 is installed above the conveyor belt 2. A fixing mechanism 3 for fixing the PCB hardware boards is installed inside the fixture tray 1. An adjustment mechanism 4 for adjusting the size of the PCB hardware boards is installed at the bottom of the fixing mechanism 3. When the fixture tray 1 containing the PCB hardware boards is conveyed by the conveyor belt 2 to the area below the camera 5, the camera 5 takes a picture of the PCB hardware boards fixed by the fixing mechanism 3 inside the fixture tray 1 and sends the picture to the control system for comparison to determine whether they are qualified.
[0022] This utility model proposes a hardware comparison and compatibility fixture for power metering equipment. The fixture tray 1 is a component used to place the PCB hardware board. It is the basic platform for supporting the PCB hardware board, providing space for the hardware board, and facilitating subsequent operation and testing.
[0023] The conveyor belt 2 is used in conjunction with the tooling pallet 1. The tooling pallet 1 is placed on the conveyor belt 2, and the operation of the conveyor belt 2 realizes the transportation of the tooling pallet 1, which contains the PCB hardware board, to the designated position for subsequent testing operations.
[0024] The fixing mechanism 3 is set inside the tooling tray 1 to fix the PCB hardware board placed in the tooling tray 1, so as to prevent the PCB hardware board from moving or shaking during the transfer or testing process, and to ensure the accuracy and stability of the test.
[0025] The adjustment mechanism 4 is located at the bottom of the fixing mechanism 3 and adjusts the size of the clamped PCB hardware board. Since PCB hardware boards of different specifications may have different sizes, the clamping range of the fixing mechanism 3 can be adjusted by the adjustment mechanism 4 to adapt to PCB hardware boards of different sizes, thereby improving the versatility and compatibility of the fixture.
[0026] Camera 5 is installed above conveyor belt 2. When the tooling tray 1 containing PCB hardware boards is transported to the area below camera 5 via conveyor belt 2, camera 5 will take pictures of the PCB hardware boards fixed by fixing mechanism 3 in tooling tray 1 to obtain image information of PCB hardware boards and provide data support for subsequent comparative testing.
[0027] First, place the PCB hardware board to be inspected in the tooling tray 1 and fix it in place using the fixing mechanism 3. If the size of the PCB hardware board does not match the initial clamping size of the fixing mechanism 3, the clamping size of the fixing mechanism 3 can be adjusted by the adjusting mechanism 4 to ensure that the PCB hardware board is stably fixed.
[0028] Next, conveyor belt 2 is started, and it begins to move, transporting the tooling tray 1 containing the PCB hardware board towards the location of camera 5. When the tooling tray 1 is transported to the position below camera 5, camera 5 automatically triggers the photo-taking function to take a picture of the PCB hardware board fixed in the tooling tray 1, thus acquiring a photo of the PCB hardware board.
[0029] Camera 5 sends the captured photos to the control system, which has pre-stored standard images or relevant parameters of qualified PCB hardware boards. The control system compares and analyzes the received photos with the standard images or parameters to determine whether the PCB hardware board is qualified.
[0030] Finally, the control system provides corresponding feedback based on the comparison results. For example, if the product is qualified, the next step is performed or it is marked as a qualified product; if the product is unqualified, an alarm is issued or it is marked as an unqualified product so that staff can carry out subsequent processing.
[0031] Combination Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the fixing mechanism 3 includes a fixing post 31 located at the bottom of the inside of the work tray 1. The top of the fixing post 31 is provided with a fixing annular groove 32 that matches the cross-section of the PCB hardware board. The bottom of the fixing post 31 is fixedly installed on the bottom of the work tray 1 by fixing bolts 33.
[0032] Specifically, the fixing column 31 is located at the bottom inside the work tray 1 and is a supporting component of the fixing mechanism 3. It is vertically installed at the bottom of the work tray 1 to provide stable support for the fixing annular groove 32 above.
[0033] The fixing annular groove 32 is located at the top of the fixing post 31 and is the part that directly contacts and fixes the PCB hardware board. Its shape matches the cross-section of the PCB hardware board. If the cross-section of the PCB hardware board is rectangular, the fixing annular groove 32 is a rectangular annular groove; if it is circular, it is a circular annular groove. This allows the fixing annular groove 32 to better fit the edge of the PCB hardware board, providing a more stable and reliable fixing effect. The depth and width of the fixing annular groove 32 also need to be precisely designed according to the size and thickness of the PCB hardware board to ensure that the hardware board is firmly fixed without causing damage to it.
[0034] The fixing bolt 33 is used to securely install the bottom of the fixing post 31 onto the bottom of the work tray 1. The fixing bolt 33 passes through the corresponding hole in the bottom of the work tray 1 and is fixedly connected to the threaded structure at the bottom of the fixing post 31. During the assembly stage, the fixing post 31 is placed in the predetermined position at the bottom of the inside of the work tray 1. Then, using an Allen wrench, the fixing bolt 33 is passed through the hole in the bottom of the work tray 1 and screwed into the threaded hole at the bottom of the fixing post 31. By rotating the fixing bolt 33, it is gradually tightened until the bottom of the fixing post 31 is in contact with the bottom of the work tray 1. The tension generated by the fixing bolt 33 firmly fixes the fixing post 31 to the work tray 1, at which point the fixing mechanism 3 is in the initial installation completed state.
[0035] When it is necessary to fix the PCB hardware board, the edge of the PCB hardware board is inserted into the fixing annular groove 32 at the top of the fixing post 31. Since the shape of the fixing annular groove 32 matches the cross-section of the PCB hardware board, the hardware board can be accurately embedded in the groove. The sidewall of the fixing annular groove 32 generates a certain amount of compressive and frictional force on the PCB hardware board, while the fixing post 31 provides vertical support for the hardware board, thereby stably fixing the PCB hardware board on the work tray 1 and preventing it from shaking, shifting, or falling during transportation or testing.
[0036] If adjustments are needed for PCB hardware boards of different sizes, first use an Allen wrench to loosen the fixing bolts 33, reducing the fixing force between the fixing post 31 and the bottom of the work tray 1. At this time, the fixing post 31 can move within a certain range inside the work tray 1. After moving the fixing post 31 to the appropriate position, tighten the fixing bolts 33 again to firmly fix the fixing post 31 to meet the fixing requirements of PCB hardware boards of different sizes.
[0037] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the adjustment mechanism 4 includes several horizontal strip grooves 41 and vertical strip grooves 42 disposed at the bottom of the work tray 1, and the fixing column 31 is slidably installed inside the horizontal strip grooves 41 and the vertical strip grooves 42 by fixing bolts 33.
[0038] Specifically, several transverse slots 41 are formed on the bottom of the work tray 1. These transverse slots 41 have a certain length and width, providing space for the fixed column 31 to move laterally. Similarly, several longitudinal slots 42 are formed on the bottom of the work tray 1, cooperating with the transverse slots 41 to form a grid-like slot structure. The longitudinal slots 42 also have suitable dimensions, allowing the fixed column 31 to move longitudinally within them.
[0039] Use a suitable tool (such as a screwdriver) to loosen the fixing bolt 33. At this time, the fixing bolt 33 releases its fixing effect on the fixing post 31, and the fixing post 31 can move freely in the transverse groove 41 and the longitudinal groove 42.
[0040] Depending on the size requirements of the PCB hardware board, the fixing post 31 is moved horizontally or vertically. If the clamping size needs to be increased, the fixing post 31 is moved away from the center of the work tray 1; if the clamping size needs to be decreased, the fixing post 31 is moved closer to the center of the work tray 1. During the movement, the fixing post 31 slides along the horizontal strip groove 41 or the vertical strip groove 42. Due to the guiding effect of the strip groove, the accuracy and stability of the movement are ensured. When the fixing post 31 is moved to the appropriate position so that the fixing mechanism 3 can just clamp the PCB hardware board of the target size, the movement of the fixing post 31 is stopped. The fixing bolt 33 is tightened again with a tool, so that the fixing bolt 33 is pressed firmly against the groove wall, and the fixing post 31 is fixed in the current position by increasing the friction. At this time, the position of the fixing mechanism 3 is also determined, and the PCB hardware board of the corresponding size can be stably fixed for subsequent operations such as photographic inspection.
[0041] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the work tray 1 has a recessed structure in the middle, and skirts 11 are provided around the work tray 1. The work tray 1 is connected to the transmission belt 2 through the skirts 11 on both sides.
[0042] Specifically, the work tray 1 adopts a unique structural design with a recessed center. The recessed part forms a relatively independent space with a certain depth, which is specifically used to place the PCB hardware board. It can provide a stable holding area for the PCB hardware board and prevent it from shifting or falling off due to shaking during transportation.
[0043] Skirts 11 are evenly distributed around the perimeter of the work tray 1. The skirts 11 are the outward extensions of the edge of the work tray 1, providing crucial structural support for the connection between the work tray 1 and the transmission belt 2. The skirts 11 surround the work tray 1, forming a complete frame structure that enhances the overall strength and stability of the work tray 1.
[0044] The work tray 1 overlaps with the transmission belt 2 via the side skirts 11. The side skirts 11 of the work tray 1 rest stably on the surface of the transmission belt 2, and the work tray 1 is stably transported on the transmission belt 2 by means of the friction between the side skirts 11 and the transmission belt 2.
[0045] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a scale 12 for measuring the dimensions of the PCB hardware board is provided on the skirt 11. Specifically, the skirt 11 has a certain width and thickness, which not only provides structural support for the overlap between the work tray 1 and the transmission belt 2, ensuring that the work tray 1 can be stably transmitted on the transmission belt 2, but also provides a suitable carrier for the setting of the scale 12.
[0046] A scale 12 is mounted on the skirt 11, with clear and precise graduations, used to measure the dimensions of the PCB hardware board. The scale 12 may be positioned along one or more edges of the skirt 11, depending on the specific measurement requirements and design layout. The unit of the scale 12 is typically millimeters (mm), a unit suitable for accurately measuring PCB hardware board dimensions, enabling operators to quickly and accurately obtain key dimensional information such as the length and width of the PCB hardware board.
[0047] Combination Figure 4 , Figure 5 and Figure 6 As shown, fixing bolt 33 is an internal hex bolt.
[0048] Specifically, the fixing bolt 33 adopts an internal hexagonal design with a cylindrical head and a regular hexagonal recessed hole at the center of one end face of the cylinder. The screw portion of the fixing bolt 33 can be screwed into the threaded hole of the fixing post 31 to connect the fixing post 31 to other components. When it is necessary to adjust the position of the fixing post 31, first loosen the fixing bolt 33 so that the fixing post 31 can slide freely in the transverse groove 41 and longitudinal groove 42 at the bottom of the work tray 1; after adjusting to the appropriate position, tighten the fixing bolt 33. The friction between the screw and the threaded hole of the fixing post 31, as well as the pressure between the screw head and the relevant contact surface, will firmly fix the fixing post 31 in the current position.
[0049] Combination Figure 3 , Figure 4 and Figure 5 As shown, the work tray 1 is made of aluminum alloy.
[0050] Specifically, the relatively low density of aluminum alloy makes the work tray 1 lighter in overall weight while maintaining a certain strength. This helps reduce the load on the transmission belt during the conveying process, lowers energy consumption, and also reduces wear on transmission components, extending the service life of the equipment. Aluminum alloy has excellent machinability, allowing for the creation of work trays 1 with complex shapes and uniform internal structures through casting, forging, and extrusion processes. This uniform material structure ensures consistent strength and performance throughout the work tray 1, avoiding localized deformation or damage caused by uneven material distribution.
[0051] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
