Description

Technical Field

[0001] This utility model relates to the field of PCB board testing technology, and more specifically, to a highly versatile PCB board testing device. Background Technology

[0002] PCB stands for Printed Circuit Board, also known as Printed Circuit Board. It is an important electronic component, serving as the support for electronic components and the carrier for electrical connections between them. Because it is manufactured using electronic printing technology, it is called a "printed" circuit board.

[0003] After PCB boards are manufactured, they must be tested using testing equipment. However, some existing PCB testing equipment has the following problems: one testing device can only test one type of PCB board, and it cannot be adapted to different types of PCB boards. If different testing devices are used to test different types of PCB boards, the procurement cost will increase significantly. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a PCB board testing device with strong versatility.

[0005] The objective of this utility model is achieved through the following technical solution: A versatile PCB board inspection device includes a base, a support and an inspection mechanism mounted on the base, a pressing mechanism mounted on the support, a pressure plate mounted on the execution end of the pressing mechanism, and a tray mounted on the base via a quick-release structure. The quick-release structure can fix trays of different sizes onto the base. The pressure plate is provided with a plurality of pins arranged in a variable combination. The tray is used to mount the PCB board to be inspected. The pressing mechanism can move the pressure plate toward the tray so that the pins contact the PCB board to be inspected.

[0006] Furthermore, in this utility model, the quick-release structure includes screws disposed on the base, and the tray has a strip hole adapted to the screws.

[0007] Furthermore, in this utility model, the pressure plate is provided with a rectangular array of several through holes adapted to the ejector pins, and the ejector pins are respectively disposed in the corresponding through holes.

[0008] Furthermore, in this utility model, the quick-release structure includes two sets of locking mechanisms symmetrically arranged on the base, which work together to fix the tray to the base.

[0009] Furthermore, in this utility model, any of the above-mentioned locking mechanisms includes a locking plate slidably disposed on the base and an adjusting bolt screwed onto the base. One end of the adjusting bolt is rotatably connected to the locking plate, and the two adjusting bolts can make the two locking plates move closer to each other or further apart.

[0010] The beneficial effects of this utility model are: This utility model provides a highly versatile PCB board testing device. After PCB boards of different sizes are fixed on the tray, a quick-release structure is installed on the base, which can fix trays of different sizes within a certain size range on the base, so that the device can test different models of PCB boards; when testing other models of PCB boards, only the tray needs to be replaced.

Detailed Implementation

[0013] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and 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.

[0014] Example 1 Please see Figures 1-4 This utility model provides a technical solution: A versatile PCB board inspection device includes a base 101, a bracket 201 mounted on the base 101, an inspection mechanism (not shown in the figure), a pressing mechanism 301 mounted on the bracket 201, a pressure plate 401 mounted on the actuating end of the pressing mechanism 301, and a tray 501 mounted on the base 101 via a quick-release structure. The pressure plate 401 has several pins 601 arranged in a variable configuration. The tray 501 is used to mount the PCB board 701 to be inspected. The pressing mechanism 301 moves the pressure plate 401 toward the tray 501 so that the pins 601 contact the PCB board 701 to be inspected. The tray 501 is used to mount PCB boards 701 of different models. The quick-release structure can accommodate trays 501 of different sizes within a certain size range, allowing the tray 501 to be quickly fixed to the base 101 and easily removed. The inspection method of the inspection mechanism is existing technology and will not be described in detail here.

[0015] Preferred, refer to Figure 3 In this embodiment, the quick-release structure includes screws (not shown in the figure) mounted on the base 101, and a slotted hole 801 adapted to the screw is provided on the tray 501. To facilitate screw installation, a screw hole is provided at a corresponding position on the base 101. After the tray 501, on which the PCB board 701 is mounted, is placed on the base 101, the screw passes through the slotted hole 801 and is threaded into the screw hole. Then, the position of the tray 501 is adjusted, and after the position is adjusted, the screw is tightened to fix the tray 501 to the base 101.

[0016] Main reference Figure 4 Since the locations to be tested differ on different PCB boards 701, this embodiment provides a rectangular array of through holes 901 on the pressure plate 401, each adapted to a probe 601. The probes 601 are then installed within their respective through holes 901. This way, when testing different PCB boards 701, the probes can be pre-installed within their respective through holes 901.

[0017] Preferred, refer to Figure 3 In this embodiment, the pressing mechanism 301 includes a rocker arm 3011, a sleeve 3012, an operating handle 3013, a connecting rod 3014, and a push rod 3015. The rocker arm 3011 and the sleeve 3012 are mounted one above the other on the bracket 201. One end of the rocker arm 3011 is hinged to the bracket 201, and the operating handle 3013 is mounted on the free end of the rocker arm 3011. The push rod 3015 is slidably mounted inside the sleeve 3012, and the pressure plate 401 is mounted on the bottom end of the push rod 3015. One end of the connecting rod 3014 is hinged to the top end of the push rod 3015, and the free end of the connecting rod 3014 is hinged to the free end of the rocker arm 3011. Thus, when it is necessary to move the pressure plate 401 towards the support plate 501, the operating handle 3013 can be rotated.

[0018] In other embodiments of this example, the pressing mechanism 301 may also employ a hydraulic rod and a lead screw and nut mechanism to achieve the above functions.

[0019] Working principle: When testing PCB board 701, first mount PCB board 701 onto tray 501, then secure tray 501 to base 101 using a quick-release mechanism. After adjusting the distribution of the probes according to the model of PCB board 701, operate pressing mechanism 301 to move the probes toward PCB board 701 until the probes contact their corresponding positions on PCB board 701. Finally, activate the testing mechanism mounted on base 101 to test PCB board 701.

[0020] Example 2 Please see Figure 5 and Figure 6 The difference between this embodiment and embodiment one is that the quick-release structure includes two sets of locking mechanisms symmetrically installed on the base 101. The two sets of locking mechanisms work together to fix the tray 501 on the base 101.

[0021] Preferably, in this embodiment, the locking mechanism includes a locking plate 1001 slidably mounted on the base 101 and an adjusting bolt 1002 screwed onto the base 101. One end of the adjusting bolt 1002 is rotatably connected to the locking plate 1001, and the two adjusting bolts 1002 can make the two locking plates 1001 move closer to each other or further away from each other.

[0022] The above structure can also quickly fix the tray 501 onto the base 101, and it can also be adapted to trays 501 of different sizes within a certain size range.

[0023] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
