Description

Technical Field

[0001] This utility model relates to the technical field of PCB testing equipment in the electronics manufacturing industry, and in particular to a load box structure for easy maintenance of testing equipment. Background Technology

[0002] In the electronics manufacturing industry, many PCBA production and testing processes require test equipment equipped with numerous peripheral loads to simulate the actual application environment of the product in order to verify its functionality. Therefore, load boxes have become an important component of such test equipment. Traditional load boxes are mostly fixed in installation. When maintenance or replacement of internal components is required, a large number of connecting parts need to be disassembled, which is cumbersome and time-consuming. At the same time, load boxes generate a lot of heat during operation, and the heat dissipation performance of traditional structures is poor, which can easily affect test accuracy and equipment lifespan. In addition, some load boxes are large in size, difficult to move, and not convenient to flexibly adjust their position according to test requirements.

[0003] In view of the shortcomings of the prior art, the present invention aims to provide a load cell structure that is easy to maintain, has efficient heat dissipation, integrated interfaces, and is easy to move. Summary of the Invention

[0004] To address the aforementioned technical problems, the purpose of this utility model is to provide a load cell structure that can be quickly pulled out and moved, has optimized heat dissipation, and has centralized interfaces, thereby solving the problems of low maintenance efficiency and heat dissipation.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A maintenance-friendly load cell structure for testing equipment, comprising:

[0007] Includes the main body of the equipment, the load box, the heavy-duty slide rails, and the operating handles;

[0008] The load box is movably mounted on the main body of the equipment via heavy-duty slide rails; and the load box is equipped with casters at the bottom, a cooling fan at the top, a connector interface panel at the back, and a load mounting plate inside.

[0009] The heavy-duty slide rail includes a fixed side and a sliding side. The fixed side is connected to the main body of the equipment, and the sliding side is connected to the load box.

[0010] The operating handle is located on the side of the load cell.

[0011] Furthermore, the cooling fan is located in the center area of ​​the top surface of the load housing, directly opposite the mounting position of the load mounting plate.

[0012] Furthermore, the connector interface panel integrates a power interface, a signal interface, and a data interface, and the connector interface panel is oriented perpendicular to the main body of the device.

[0013] The load mounting plate is a detachable mesh plate, which is fixed to the inner wall of the load box by bolts.

[0014] Furthermore, the caster is a swivel caster with a self-locking structure.

[0015] Furthermore, the number of cooling fans is at least one, and they are spaced apart along the length of the top of the load cell.

[0016] Compared with the prior art, one or more embodiments of this utility model may have the following advantages:

[0017] 1) Easy maintenance: The load box can be smoothly pulled out through the combination of slide rails and casters. It can be operated by a single person, reducing maintenance time by more than 50%.

[0018] 2) Highly efficient heat dissipation: The cooling fan installed on the top can directly expel heat, improving heat dissipation efficiency by 30%;

[0019] 3) The structure is stable. The load mounting plate and heavy-duty slide rail keep the load box stable during movement and prevent equipment damage.

[0020] 4) Interface optimization: The rear-mounted connector interface panel simplifies the docking process and reduces the risk of connection errors. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] like Figure 1-4As shown, the present invention provides a convenient load box structure for testing equipment, including the main body of the equipment 1, the load box body 2, the heavy-duty slide rail 3, the casters 4, the cooling fan 5, the connector interface panel 6, the load mounting plate 7, and the operating handle 8.

[0028] The load box 2 is movably mounted on the main body 1 via a heavy-duty slide rail 3; and the load box 2 is equipped with casters 4 at the bottom, a cooling fan 5 at the top, a connector interface panel 6 at the back, and a load mounting plate 7 inside.

[0029] The heavy-duty slide rail 3 includes a fixed side and a sliding side. The fixed side is connected to the main body 1 of the equipment, and the sliding side is connected to the load box 2.

[0030] The operating handle 8 is located on the side of the load cell 2. The heavy-duty pulleys and casters assist the load cell in moving back and forth along the main body of the equipment.

[0031] The cooling fan 5 is located in the center area of ​​the top surface of the load housing 2, directly opposite the mounting position of the load mounting plate 7, which facilitates the dissipation of heat generated when the load is working.

[0032] The connector interface panel 6 is connected to the rear end of the load housing 2 by a snap-fit, and integrates a power interface, a signal interface and a data interface. The connector interface panel 6 is oriented perpendicular to the main body of the device 1, and is used to realize the circuit connection between the load and the test equipment.

[0033] The load mounting plate 7 is a detachable grid plate, which is fixed to the inner wall of the load box 2 by bolts, making it easy to install the load used by the main body of the equipment.

[0034] The caster 4 is a swivel caster with a self-locking mechanism.

[0035] The number of cooling fans 5 is at least one, and they are distributed at intervals along the length of the top of the load cell 2. In this embodiment, two cooling fans are provided, symmetrically distributed along the length of the top of the load cell 2, and fixed to the preset mounting holes on the top with screws. The fan outlets face upwards, so that the heat inside the cell can be directly discharged.

[0036] During maintenance, the operator unlocks caster 4, grasps operating handle 8, and pulls the load box outward. Guided by the heavy-duty slide rail 3 and the rolling action of caster 4, the load box 2 smoothly moves out of the main body 1 along the slide rail 3 (e.g., Figure 3 As shown), after fully pulling out the cable, lock the caster 4 and disconnect the cable through the rear interface panel 6. At this time, the internal load components can be inspected or replaced. After maintenance, push the operating handle 8 in the opposite direction to push the load box 2 into the main body 1 of the equipment. The interface panel 6 will automatically connect with the main body 1 of the equipment, and the caster 4 can be locked.

[0037] The load cell structure described above achieves convenient maintenance, smooth movement, and good heat dissipation through a reasonable component layout and connection method, making it suitable for load configuration of PCB testing equipment in the electronics manufacturing industry.

[0038] Although the embodiments disclosed in this utility model are as described above, the content described is merely for the purpose of facilitating understanding of this utility model and is not intended to limit this utility model. Any person skilled in the art to which this utility model pertains may make any modifications and changes in the form and details of the implementation without departing from the spirit and scope disclosed in this utility model, but the patent protection scope of this utility model shall still be determined by the scope defined in the appended claims.
