Description

Technical Field

[0001] This utility model relates to the field of testing fixture technology, and in particular to a simple manual testing fixture. Background Technology

[0002] FCT (Functional Circuit Test) is a crucial step in verifying the various functions of a product during the trial production phase. It simulates the product's operation in a real-world environment by applying power and input stimulus signals to the PCBA and collecting output responses to determine if its functionality meets design specifications. Currently, the common practice is to create dedicated FCT manual test fixtures (including cabinet assemblies, panels, carrier board assemblies, pin assemblies, and pressure-down assemblies) for different product versions during the trial production phase. These fixtures are placed on a standard workbench for connecting the PCBA to the test system for testing.

[0003] Existing FCT manual testing fixtures are typically a single, integrated design, comprising a housing assembly, panel assembly, carrier plate assembly, needle plate assembly, and pressing assembly, resulting in a complex structure and numerous components. Furthermore, fixtures are required for different stages of trial production, which often involves small-batch production and rapid version iterations. This leads to high fixture costs and long production times, resulting in poor reusability and high overall cost for FCT manual testing fixtures. Additionally, the large size and weight of the integrated fixture make testing and storage space-consuming and inconvenient to move. Moreover, during testing, the quick-clamp handle in the quick-clamp pressing assembly is usually pulled, but the handle's raised position is often quite high, making it difficult for employees to operate. Utility Model Content

[0004] This utility model provides a simple manual testing fixture to solve at least one of the problems of high cost, large size, and inconvenient operation of existing FCT manual testing fixtures.

[0005] According to one aspect of the present invention, a simple manual testing fixture is provided, including a first mold and a second mold that can be combined with each other to clamp and fix the product to be tested. A snap-fit ​​structure is provided between the first mold and the second mold to realize the combination of the first mold and the second mold. A handle is provided on the first mold and the handle is located on one side of the snap-fit ​​structure.

[0006] This utility model's simplified manual testing fixture achieves the installation and fixation of the product to be tested through the assembly of a first mold and a second mold. In this design, the first and second molds are assembled using a snap-fit ​​structure. Furthermore, a handle is provided near the snap-fit ​​structure, allowing the user to easily interact with the structure using their fingers while holding the handle, enabling rapid installation of the FCT manual testing fixture. Simultaneously, the simplified manual testing fixture eliminates the need for quick clamps and a housing structure, resulting in a simpler overall structure and reduced overall cost.

[0007] In some embodiments, the snap-fit ​​structure includes a snap-fit ​​block hinged to the second mold, which, when snapped onto the first mold, enables the combination of the first mold and the second mold.

[0008] Therefore, by using this design, the combination of the first mold and the second mold can be achieved by using the snap-fit ​​block to engage with the first mold, making the overall structure easy to operate.

[0009] In some embodiments, the latching block is provided with a first elastic element that drives it to rotate and latch onto the first mold.

[0010] Therefore, this configuration allows the first elastic element to continuously engage the latching block with the first mold, ensuring that there will be no instability during testing.

[0011] In some embodiments, the first mold is provided with a slot corresponding to the snap-fit ​​block, and the snap-fit ​​block is fastened to the slot to realize the combination of the first mold and the second mold.

[0012] Therefore, this design allows for the use of slots to further preserve the fixed position of the first and second molds during installation.

[0013] In some embodiments, the second mold includes a carrier plate assembly and a needle plate assembly. The carrier plate assembly is provided with a placement slot for placing the product to be tested. The carrier plate assembly is disposed on the needle plate assembly, and a second elastic member is provided between the carrier plate assembly and the needle plate assembly to drive the carrier plate assembly away from the needle plate assembly.

[0014] Therefore, with this configuration, the needle plate assembly and the mounting plate can be driven to move toward the direction of the first mold by the second elastic element, so as to ensure that after the first mold and the second mold are installed, the product to be tested can be more stably installed between the first mold and the second mold, and the second elastic element can also be used to maintain pressure on the product to be tested.

[0015] In some embodiments, the needle plate assembly includes a second template, the carrier plate assembly includes a mounting plate, the mounting slot is disposed on the mounting plate, a guide pin is provided on the side of the mounting plate facing the second template, and a linear bearing that cooperates with the guide pin is disposed on the second template.

[0016] Therefore, by using guide pins and linear bearings, the mounting plate and the second template can be aligned, ensuring the accurate positioning of the product to be tested after assembly.

[0017] In some embodiments, the second template is provided with a second probe structure, and the mounting plate is provided with perforations for the second probe structure to pass through.

[0018] Therefore, with this configuration, under the action of the second elastic element, when the second mold is combined with the first mold, the second probe structure can pass through the perforation on the mounting plate and contact the product to be tested, thus achieving connection with the product to be tested.

[0019] In some embodiments, the first mold includes a first template, the handle is disposed on the side away from the second mold when the first template is installed onto the second mold, and the first template is provided with a first probe structure that penetrates through the first template.

[0020] Therefore, by setting it up in this way, the test points on the other side of the product to be tested can be connected using the first template.

[0021] In some embodiments, a positioning pin is provided on the side of the first template facing the second mold, and a bushing is provided on the second mold to cooperate with the positioning pin.

[0022] Therefore, this setup allows for the alignment of the first and second molds using positioning pins and bushings, ensuring that the assembled first and second molds can be accurately fixed and connected to the product to be tested.

[0023] In some embodiments, the mounting plate is provided with a positioning structure for positioning the product under test. The positioning structure includes a coarse positioning block and a fine positioning pin. The top surface of the coarse positioning block is provided with an inclined surface, and the fine positioning pin is configured to correspond to the position of an opening on the product under test. Therefore, with this setup, when the product under test is installed on the mounting plate, its position can be roughly adjusted by the inclined surface set on the coarse positioning block, and then the fine positioning pin can be used to cooperate with the opening on the product under test, so that the product under test can be easily and accurately positioned and installed on the mounting plate.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings.

[0034] Figure 1 The overall composition of a simple manual testing fixture according to one embodiment of this utility model is illustrated schematically. (Refer to...) Figure 1 As shown, the simple manual testing fixture of this utility model includes a first mold 1 and a second mold 2. The first mold 1 and the second mold 2 are combined to clamp and fix the product to be tested, ensuring the accuracy of the product's position during testing. A snap-fit ​​structure 3 is provided between the first mold 1 and the second mold 2 to facilitate their combination. A handle 4 is provided on the first mold 1, located on one side of the snap-fit ​​structure 3.

[0035] With the above settings, when in use, since the handle 4 is located near the buckle structure 3, the operator can grasp the handle 4 and interact with the buckle structure 3 through their fingers to achieve the combination and disassembly of the first mold 1 and the second mold 2, thereby realizing the quick installation and disassembly of the FCT manual test fixture.

[0036] The snap-fit ​​structure 3 can adopt a structure commonly used in existing technologies, such as a flip-top structure. (Refer to...) Figure 2 As shown, a set of snap-fit ​​structures 3 can be provided on each of the two sides of the second mold 2. Similarly, refer to... Figure 2 As shown, a set of handles 4 can also be provided on each side of the first mold 1. The design of the two sets of buckle structures 3 can make the connection between the first mold 1 and the second mold 2 more stable, while the design of the two handles 4 can allow the operator to grip the handles 4 with both hands to operate, making the operation more stable.

[0037] In some possible implementations, the snap-fit ​​structure 3 may include a snap-fit ​​block 31 hinged to the second mold 2. Since the snap-fit ​​block 31 is hinged to the second mold 2, when the operator operates the snap-fit ​​block 31 to engage, the operator can rotate the snap-fit ​​block 31 with their fingers to engage the first mold 1, thereby achieving the assembly between the first mold 1 and the second mold 2.

[0038] In other possible embodiments, the latching block 31 may also be provided with a first elastic element that drives it to rotate and latch onto the first mold 1. The first elastic element can be a sheet, spring, torsion spring, or similar structure. By adding a first elastic element to the latching block 31, the latching block 31 can be more securely latched onto the first mold 1, preventing loosening and detachment, and improving the installation stability between the first mold 1 and the second mold 2. Simultaneously, when the operator operates the latch to engage, they only need to open the latching block 31 with their fingers, assemble the first mold 1 onto the second mold 2, and release their fingers to achieve the latching of the latching block 31, making the operation simpler and more convenient. Furthermore, the latching block 31 can be configured as a wedge-shaped structure. The inclined surface of the wedge-shaped structure abuts against the first mold 1, thereby automatically squeezing the latching block 31 open, further eliminating the need for the operator to manually open the latching block 31, making the operation even simpler and more convenient.

[0039] Furthermore, in some other possible embodiments, the first mold 1 may also be provided with a slot 32 corresponding to the snap-fit ​​block 31. Specifically, the size of the slot 32 may match the size of the snap-fit ​​block 31 when it is fastened to the first mold 1, so that after the first mold 1 and the second mold 2 are combined, the snap-fit ​​block 31 restricts the vertical movement of the first mold 1 and the slot 32 restricts the horizontal movement of the first mold 1, thereby achieving the fixation between the first mold 1 and the second mold 2.

[0040] Specifically, refer to Figure 2 and Figure 4 As shown, Figure 2 and Figure 4 The diagram schematically illustrates the composition of the snap-fit ​​structure 3 in a simple manual testing fixture according to one embodiment of this utility model. Figure 2 and 4 In the embodiments shown, refer to Figure 2 The snap-fit ​​structure 3 consists of a snap-fit ​​block 31 disposed on the second mold 2 and a snap-fit ​​groove 32 disposed on the first mold 1. (Refer to...) Figure 4The latching block 31 is designed with a wedge shape and an inclined surface. The latching block 31 is hinged to a connecting component, and a torsion spring is provided at the hinge position. The connecting component is connected to the second mold 2 to achieve the installation of the latching block 31. Specifically, the connecting component can be connected to the second mold 2 by screws or integrated into the design; this embodiment does not limit this. When the first mold 1 is pushed towards the second mold 2 by an external force, the bottom surface of the first mold 1 will first abut against the inclined surface of the latching block 31, thereby squeezing and pushing the latching block 31 to open against the elastic force of the torsion spring. After the top surface of the first mold 1 passes the inclined surface of the latching block 31, the latching block 31 will be engaged with the slot 32 of the first mold 1 under the elastic force of the torsion spring, thus limiting and fixing the slot 32. When the operator needs to disassemble the first mold 1, they only need to hold the handle 4 and use their fingers to pry open the latching block 31 to remove the first mold 1; the whole process is simple and quick.

[0041] In this embodiment, the second mold 2 is a mold part used to mount the product to be tested. The second mold 2 includes a carrier plate assembly 21 and a pin plate assembly 22. The carrier plate assembly 21 is used to mount the PCB board of the product to be tested, and the pin plate assembly 22 is used to connect with the PCB board of the product to be tested to enable testing of the product. Specifically, the carrier plate assembly 21 may include a mounting slot 51 for placing the product to be tested. The carrier plate assembly 21 is disposed on the pin plate assembly 22, and a second elastic member is provided between the carrier plate assembly 21 and the pin plate assembly 22 to drive the carrier plate assembly 21 away from the pin plate assembly 22. At this time, the snap-fit ​​structure 3 disposed on the second mold 2 can specifically be disposed on the pin plate assembly 22, so that after the first mold 1 and the second mold 2 are combined, the carrier plate assembly 21 for placing the product to be tested can be driven towards the first mold 1 under the action of the second elastic member, ensuring that after the first mold 1 and the second mold 2 are installed, the product to be tested can be more stably mounted between the first mold 1 and the second mold 2, while also utilizing the second elastic member to maintain pressure on the product to be tested.

[0042] Specifically, to ensure that the carrier plate assembly 21 does not shift position when driven, a guide structure can be provided between the needle plate assembly 22 and the carrier plate assembly 21. (Refer to...) Figure 4As shown, the needle plate assembly 22 includes a second template 6, and the carrier plate assembly 21 includes a mounting plate 5. A placement groove 51 is disposed on the mounting plate 5, and a guide pin 55 extends from the side of the mounting plate 5 facing the second template 6. A linear bearing 61 is disposed on the second template 6, which cooperates with the guide pin 55. Therefore, when the mounting plate 5 is installed on the second template 6, the guide pin 55 is inserted into the linear bearing 61, guiding the movement of the mounting plate 5. A second elastic element is disposed between the second template 6 and the mounting plate 5. Thus, after the first mold 1 and the second mold 2 are assembled, the mounting plate 5, driven by the second elastic element, can push the product to be tested placed in the placement groove 51 towards the first mold 1, achieving a pressure-holding function for the product to be tested.

[0043] The bottom surface of the second template 6 can also be equipped with a support plate 62, which can provide support for the entire second mold 2. (See reference...) Figure 4 As shown, there can be two foot support plates 62, each foot support plate 62 is provided with two support feet, so that the second template 6 has four support feet, and the four support feet are evenly distributed at the bottom of the second mold 2.

[0044] In addition, continue to refer to Figure 4 As shown, an equal-height screw 54 can also be provided between the mounting plate 5 and the second template 6, so that the maximum distance between the mounting plate 5 and the second template 6 can be limited by the equal-height screw 54, so as to prevent the mounting plate 5 from being pushed out by the second elastic element when the second mold 2 is not assembled with the first mold 1.

[0045] At the same time, continue to refer to Figure 4 As shown, a second probe structure 63 can be provided on the second template 6, and perforations for the second probe structure 63 to pass through can be provided on the mounting plate 5. Specifically, the positions of these perforations correspond one-to-one with the positions of each probe on the second probe structure 63, so that after the product to be tested is placed on the second mold 2, the probes on the second mold 2 can contact the product to be tested, thereby realizing the testing of the product to be tested.

[0046] In some possible implementations, the mounting plate 5 may also be provided with a positioning structure for positioning the product to be tested. Specifically, refer to... Figure 4 As shown, the positioning structure includes a coarse positioning block 52 and a fine positioning pin 53. The top surface of the coarse positioning block 52 is provided with an inclined surface, while the fine positioning pin 53 is configured to correspond to the opening position on the product under test. This configuration allows for a rough adjustment of the product's position when it is placed on the mounting slot 51, using the inclined surface of the coarse positioning block 52, and then precise positioning and installation of the product under test is achieved through the cooperation between the fine positioning pin 53 and the product under test.

[0047] The first mold 1 is a structure for connecting probes to the surface portion of the product to be tested. The first mold 1 includes a first template 11, and a handle 4 is mounted on the first template 11, specifically on the side of the first template 11 away from the second mold 2 when it is installed onto the second mold 2. A first probe structure 12 is provided on the first template 11, and the first probe structure 12 penetrates the first template 11 so that after the first mold 1 is installed onto the second mold 2, the first probe structure 12 can contact the product to be tested, thereby enabling testing of the product.

[0048] Specifically, refer to Figure 3 As shown, a pressure bar 14 can be provided on the bottom surface of the first template 11. The pressure bar 14 can provide pressure to the product under test after the first mold 1 and the second mold 2 are assembled, achieving pressure holding of the product under test. The pressure bar 14 can be made of a material with elastic deformation properties, such as soft rubber, to ensure that the product under test is not damaged during pressure holding and to further improve the pressure holding performance. In addition, a positioning pin 13 can be extended from the side of the first template 11 facing the second mold 2, and a bushing 64 that mates with the positioning pin 13 is provided on the second mold 2. The engagement between the positioning pin 13 and the bushing 64 enables the assembly connection and positioning between the first mold 1 and the second mold 2, ensuring that the probe on the first mold 1 accurately aligns with the test point on the product under test. Meanwhile, continuing to refer to... Figure 4 As shown, bushing 64 can be simultaneously installed on mounting plate 5 and second template 6, thereby enabling simultaneous positioning of mounting plate 5, second template 6 and first template 11. This ensures that after the product to be tested is placed on mounting plate 5, the test points before and after it can be accurately connected, thus ensuring the normal conduct of the test.

[0049] This utility model's simplified manual testing fixture achieves the installation and fixation of the product to be tested by assembling a first mold 1 and a second mold 2. In this design, the first mold 1 and the second mold 2 are assembled using a snap-fit ​​structure 3. Furthermore, a handle 4 is provided near the snap-fit ​​structure 3, allowing the user to easily interact with the snap-fit ​​structure 3 using their fingers while holding the handle 4, thus enabling rapid installation of the FCT manual testing fixture. Simultaneously, the simplified manual testing fixture eliminates the need for quick clamps and a housing structure, resulting in a simpler overall structure and reduced overall cost.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
