Description

Technical Field

[0001] This application relates to the field of testing fixture technology, and in particular to a Kmamingxin V5 to Lide M6 needle testing fixture. Background Technology

[0002] In the circuit board manufacturing process, it is usually necessary to test the circuit board using a wire needle fixture to detect whether there are open circuits, short circuits, or resistance issues. Current wire needle fixtures include an upper mold and a lower mold, both of which are equipped with probes. The circuit board is placed on the lower mold, and then the probes of the lower mold contact the contacts on the bottom surface of the circuit board. Then, the testing machine drives the upper mold to move downwards, so that the probes of the upper mold contact the contacts on the top surface of the circuit board.

[0003] Currently, pin fixtures are typically mounted on testing machines, and testing is completed by the pin fixtures contacting the circuit boards. The customer's existing testing machines are from Nidec, KEMA Technology, and Mingxin Electronics. KEMA and Mingxin's testing machines are V5 models, while Nidec's are M6 models. Due to the different models and sizes of these machines, different types of pin fixtures are required for different testing machines, resulting in incompatibility and some machines being idle, thus hindering maximum production capacity. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a Kmamin V5 to Lide M6 pin test fixture, comprising a base plate mounted on a testing machine, a pad detachably mounted on the base plate, several support columns detachably mounted on the pad, pin fixtures mounted on the support columns, an adjustment plate installed inside the pin fixture, trays detachably mounted on both sides of the adjustment plate, several probes threaded through the pin fixture, and a terminal block electrically connected to the probes provided on the base plate.

[0005] Preferably, the bottom of the support column is formed with a threaded post, and the threaded post of the support column is threadedly connected to the pad or the base plate.

[0006] Preferably, the needle fixture is connected to the top of the support column by bolts.

[0007] Preferably, the needle fixture includes a mounting plate through which the probe can pass, several first guide plates, and several second guide plates. The mounting plate is provided with a support column that passes through the first guide plate, the adjustment plate is installed on top of the support column, and the second guide plates are stacked on the adjustment plate.

[0008] Preferably, mounting edges are formed on both sides of the adjusting plate, and the support plate is detachably connected to the mounting edges by screws.

[0009] Preferably, the mounting plate is detachably connected to alignment pins for aligning the PCB board, and the alignment pins are sequentially inserted through a plurality of first guide plates, an adjustment plate, and a plurality of second guide plates.

[0010] Preferably, a guide post is inserted into the mounting plate, and the guide post passes through several first guide plates and several second guide plates.

[0011] Preferably, a light guide hole is provided through the adjustment plate, the mounting plate, the first guide plate, and the second guide plate.

[0012] As can be seen from the above, the following beneficial effects can be obtained by applying the method provided in this application: A pad can be detachably installed on the base plate, on which several support columns are detachably installed. A needle fixture is installed on each support column, and an adjustment plate is installed inside the needle fixture. Support plates are detachably installed on both sides of the adjustment plate. Several probes are threaded through the needle fixture. A terminal block electrically connected to the probes is provided on the base plate. When the base plate is installed on the testing machine, the probes are connected to the testing machine through the terminal block, and the test is completed by the probes contacting the contacts on the circuit board surface. When changing to different models of testing machines, the pad and support plates can be removed or installed, allowing the needle fixture to be installed on the pad or base plate via the support columns. This changes the overall height of the needle-thread testing fixture, thus adapting it to different models of testing machines, meeting the requirement that the testing fixture can be installed on different testing machines, improving compatibility, avoiding downtime of the testing machine on-site, and maximizing production capacity.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0019] Example

[0020] To address the aforementioned technical problems, this embodiment provides a Kmamin V5 to Lide M6 thread needle testing fixture, such as... Figure 1-2 As shown, the test equipment includes a base plate 10 mounted on a testing machine and a pad 20 detachably mounted on the base plate 10. Several support columns 30 are detachably mounted on the pad 20, and a needle fixture 40 is mounted on the support columns 30. An adjustment plate 50 is installed inside the needle fixture 40, and a support plate 51 is detachably mounted on both sides of the adjustment plate 50. Several probes 60 are threaded through the needle fixture 40. A terminal block 11 electrically connected to the probes 60 is provided on the base plate 10. When the base plate 10 is mounted on the testing machine, the probes 60 are connected to the testing machine through the terminal block 11, and the test is completed by the probes 60 contacting the contacts on the surface of the circuit board. When changing to different models of testing machines, the pad 20 and the support plate 51 can be disassembled or installed, so that the needle fixture 40 can be installed on the pad 20 or the base plate 10 through the support column 30. This changes the overall height of the needle and thread testing fixture, thereby adapting it to different models of testing machines, meeting the requirement that the testing fixture can be installed on different testing machines, improving compatibility, avoiding downtime of testing machines on site, and maximizing production capacity.

[0021] Furthermore, a threaded post is formed at the bottom of the support column 30, and the threaded post of the support column 30 is threadedly connected to the pad 20 or the base plate 10. This enables a detachable connection between the support column 30 and the pad 20 or the base plate 10. When the pad 20 is used, the support column 30 is threadedly connected to the pad 20; when the pad 20 is not used, the support column 30 is threadedly connected to the base plate 10.

[0022] Furthermore, the needle fixture 40 is connected to the top of the support column 30 by bolts, thereby making the needle fixture 40 and the support column 30 detachably connected. Alternatively, in some other embodiments, the height of the needle fixture 40 can be adjusted by replacing the support column 30 with one of different heights.

[0023] Furthermore, the needle fixture 40 includes a mounting plate 41 through which the probe 60 can pass, several first guide plates 42, and several second guide plates 43. A support post 44 is provided on the mounting plate 41, passing through the first guide plates 42. An adjusting plate 50 is mounted on top of the support post 44, and the second guide plates 43 are stacked on the adjusting plate 50. Guide posts 45 are inserted into the mounting plate 41, passing through the first guide plates 42 and the second guide plates 43. During assembly of the needle fixture 40, the guide posts 45 guide and position the first guide plates 42 and the second guide plates 43, ensuring assembly accuracy. The mounting plate 41 is connected to the support post 44 by screws, and the multiple second guide plates 43 are connected to the top of the support post 44 by screws, thus the support post 44 supports the guide plates 43.

[0024] Furthermore, a positioning PI n70 for aligning the PCB board is detachably connected to the mounting plate 41. The positioning PI n70 is sequentially inserted through several first guide plates 42, adjusting plates 50, and several second guide plates 43. The bottom of the positioning PI n70 is threadedly connected to the mounting plate 41. When the model requires the positioning PI n70 to position the PCB board, the positioning PI n70 can be installed on the mounting plate 41 to meet the positioning requirements.

[0025] Furthermore, mounting edges 52 are formed on both sides of the adjusting plate 50. The support plate 51 is detachably connected to the mounting edges 52 by screws, so that the support plate 51 can be installed or removed according to the installation requirements of different models to achieve compatibility. At the same time, light guide holes 80 are provided through the adjusting plate 50, the mounting plate 41, the first guide plate 42 and the second guide plate 43. When some models need to install camera devices, the camera is positioned by pre-drilling light guide holes 80.

[0026] Specifically, the workshop currently uses the KEMAM M5 testing machine and the Lide M6 testing machine. For example, because each thread needle fixture has a uniform height of 40mm, such as... Figure 3 As shown, when the pin fixture 40 is installed on the Kma Mingxin V5 model, due to insufficient overall height, a pad 20 needs to be installed on the base plate 10, and then the support column 30 is connected to the pad 20. The pin fixture 40 is then fixed to the support column 30 to meet the height requirements for installation in the testing machine. Then, a support plate 51 is connected to the mounting edges 52 on both sides of the adjusting plate 50, and an alignment pin 70 is installed on the mounting plate 41 to meet the alignment requirements of the PCB board.

[0027] like Figure 4As shown, when the needle fixture 40 is installed on the Ride M6 model, the pad 20 is removed, allowing the support column 30 to connect to the base plate 10. The tray 51 is then removed from the adjusting plate 50, and the alignment pin 70 is removed from the mounting plate 41, thus meeting the usage requirements of the Ride M6 model. Multiple pads 20 of different sizes can be produced to adapt to various types of testing machines.

[0028] In summary, this application's solution involves a detachable mounting plate on a base plate, on which several support columns are detachably mounted. A needle fixture is mounted on each support column, and an adjustment plate is installed within the needle fixture. Support plates are detachably mounted on both sides of the adjustment plate. Several probes are threaded through the needle fixture. A terminal block electrically connected to the probes is provided on the base plate. When the base plate is mounted on a testing machine, the probes connect to the testing machine via the terminal block, and testing is completed by the probes contacting the contacts on the circuit board surface. When changing to different models of testing machines, the mounting plate and support plates can be removed or installed, allowing the needle fixture to be mounted on either the mounting plate or the base plate via the support columns. This changes the overall height of the needle-thread testing fixture, adapting it to different models of testing machines, meeting the requirement that the testing fixture can be installed on different testing machines, improving compatibility, avoiding downtime of testing machines on-site, and maximizing production capacity.

[0029] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
