Description

Technical Field

[0001] The present application relates to the field of testing technology, and in particular to a testing machine. Background Art

[0002] In existing test machines, the PCB mounting base and the machine housing are typically fixed together using locking screws. A cable connects the PCB mounted on the PCB mounting base to the test circuit board inside the machine housing. To change the cable's interface to the PCB, the operator must first loosen the locking screw, change the cable plug, and then tighten the screw again. This process is cumbersome, time-consuming, and inefficient. Summary of the Invention

[0003] The purpose of the embodiments of the present application is to provide a testing machine to improve the problems of the prior art in changing cable plugs, such as complicated procedures, long time consumption, and low efficiency.

[0004] In a first aspect, an embodiment of the present application provides a test machine, which includes a machine housing, a test circuit board, a PCB board, and a PCB mounting base plate; the test circuit board is arranged inside the machine housing, the PCB board is fixedly connected to the PCB mounting base plate, and the PCB mounting base plate is movably connected to the machine housing; the PCB board is provided with a plurality of first interfaces, and the test circuit board is provided with a second interface, and any first interface of the plurality of first interfaces is connected to the second interface via a cable; the PCB mounting base plate is configured to be displaceable relative to the machine housing, thereby facilitating replacement of the first interface connected by the cable.

[0005] In the above-described embodiment, when performing functional testing on a PCB board, the first interface for connecting a cable often needs to be frequently changed. The PCB mounting base is movably connected to the machine housing, and the PCB mounting base is configured to be movable relative to the machine housing. This allows a worker to move the PCB mounting base relative to the machine housing when changing the first interface for connecting a cable. This increases the operable space between the machine housing and the PCB mounting base, thereby facilitating a quicker change of the first interface for connecting a cable, reducing time consumption, and improving efficiency.

[0006] In a possible design, the PCB mounting base is slidably connected to the machine housing.

[0007] In the above-described embodiment, the PCB mounting base and the machine housing may be movably connected via a sliding connection. It is understood that the PCB mounting base and the machine housing may be movably connected via a sliding connection or other movably connected methods, such as a rotational connection. The specific method of movably connecting the PCB mounting base and the machine housing should not be construed as limiting the present application.

[0008] In one possible design, the machine housing is provided with a guide support rod, the PCB mounting base plate is provided with a through hole matching the guide support rod, the through hole of the PCB mounting base plate is sleeved on the corresponding guide support rod, and the PCB mounting base plate is configured to be able to slide relative to the machine housing along the extension direction of the guide support rod.

[0009] In the above-described embodiment, the machine housing may be provided with a guide support rod, and the PCB mounting base plate may be provided with a through hole that matches the guide support rod. The PCB mounting base plate may be sleeved with the guide support rod through the through hole, allowing the PCB mounting base plate to slide along the extension direction of the guide support rod. When a worker desires to change the first interface for the cable connection, the PCB mounting base plate may be slid away from the machine housing, thereby increasing the available space between the PCB mounting base plate and the machine housing, allowing the worker to quickly and easily change the first interface for the cable connection.

[0010] In a possible design, a linear bearing is further included, which is arranged on the inner side of the corresponding through hole and sleeved on the corresponding guide support rod.

[0011] In the above-mentioned embodiment, the linear bearing can reduce the sliding resistance between the PCB mounting base and the machine housing, thereby extending the service life of the test machine and reducing maintenance costs.

[0012] In a possible design, the PCB mounting base is rotatably connected to the machine housing.

[0013] In the above-described embodiment, the PCB mounting base and the machine housing can be movably connected via a rotational connection. It is understood that the PCB mounting base and the machine housing can be movably connected via a rotational connection or other movably connected methods, such as a sliding connection. The specific method of movably connecting the PCB mounting base and the machine housing should not be construed as limiting this application.

[0014] In a possible design, one side of the PCB mounting base is connected to the machine housing via a hinge.

[0015] In the above embodiment, one side of the PCB mounting base can be hinged to the machine housing via a hinge. When a worker desires to change the first interface for the cable connection, the PCB mounting base can be rotated away from the machine housing about the hinge axis, thereby increasing the available clearance between the PCB mounting base and the machine housing, allowing the worker to quickly and easily change the first interface for the cable connection.

[0016] In a possible design, a side of the PCB mounting base away from the hinge is connected to the machine housing via a snap-fit ​​connection.

[0017] In the above embodiment, the side of the PCB mounting base away from the hinge can be connected to the machine housing by a snap connection. The snap connection can easily connect and separate the PCB mounting base and the machine housing, thereby further improving the convenience of the movable connection between the PCB mounting base and the machine housing.

[0018] In a possible design, it further includes a bracket and a rotating mechanism, and the machine housing and the bracket are rotatably connected through the rotating mechanism.

[0019] The aforementioned embodiment may further include a bracket and a rotation mechanism. The machine housing may be mounted on the bracket and rotatable relative to the bracket via the rotation mechanism. Rotation of the machine housing relative to the bracket facilitates changing the relative angle between the machine housing and a worker, facilitating a more comfortable position for the worker to operate the test machine, thereby further improving the speed of changing the cable connection to the first interface and enhancing efficiency.

[0020] In one possible design, the rotating mechanism includes a rotating shaft and multiple bearings; the rotating shaft is fixedly connected to the machine housing, the multiple bearings are all arranged on the bracket, and the machine housing and the bracket are connected in rotation through the cooperation of the rotating shaft and the multiple bearings.

[0021] In the above embodiment, the machine housing and the bracket can be rotatably connected by means of a rotating shaft and a bearing. The bearing can reduce the wear and tear between the machine housing and the bracket during rotation, thereby extending the service life of the machine housing and the bracket.

[0022] In one possible design, the rotating mechanism includes a rotating positioning plate and a knob plunger. The rotating positioning plate is fixedly connected to the machine housing. The rotating positioning plate is provided with multiple positioning holes. The knob plunger cooperates with the multiple positioning holes to limit the machine housing to multiple angles.

[0023] In the above-mentioned embodiment, the rotating mechanism may include a rotating positioning plate and a knob plunger. The rotating positioning plate is provided with a plurality of positioning holes. The knob plunger cooperates with the positioning holes to limit the machine housing at a specific angle. Fixing the machine housing at certain specific angles can facilitate the staff to operate the test machine and improve the staff's work efficiency.

[0031] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0032] See Figure 1 , Figure 1The test machine provided in an embodiment of the present application is shown. The test machine includes a machine housing 110, a test circuit board 120, a PCB 130, and a PCB mounting base 140. The test circuit board 120 is disposed within the machine housing 110, the PCB 130 is fixedly connected to the PCB mounting base 140, and the PCB mounting base 140 is movably connected to the machine housing 110. The test circuit board 120 is a circuit board within the test machine that provides resources such as voltage and current. It is also called a test resource board.

[0033] The machine housing 110 can be a rectangular frame structure. The entire test system (not shown) can be mounted inside the machine housing 110. Ventilation and heat dissipation vents can be left on the side walls of the machine housing 110. An air intake fan (not shown) and an exhaust fan (not shown) can be installed at the upper and lower ends of the machine housing 110, respectively, to enhance air circulation inside the positive electrode when the test machine is in operation.

[0034] The test circuit board 120 may be a component that provides power and signal sources for the PCB board 130. The PCB mounting base plate 140 is used to support the PCB board 130, and the PCB mounting base plate 140 may be a rectangular plate.

[0035] The PCB board 130 is provided with a plurality of first interfaces 131, see Figure 3 The test circuit board 120 is provided with a second interface 121, and any first interface 131 of the plurality of first interfaces 131 is connected to the second interface 121 via a cable (not shown). The PCB mounting base 140 is configured to be movable relative to the machine housing 110, thereby facilitating replacement of the first interface 131 connected by the cable.

[0036] In one embodiment, see Figure 1 and Figure 3 The PCB mounting base plate 140 is slidably connected to the machine housing 110. The machine housing 110 is provided with a guide support rod 111. The PCB mounting base plate 140 is provided with a through hole 141 matching the guide support rod 111. The through hole 141 of the PCB mounting base plate 140 is sleeved on the corresponding guide support rod 111.

[0037] Optionally, there may be four guide support rods 111. Correspondingly, the PCB mounting base plate 140 also has four through holes 141 corresponding to the guide support rods 111. The extension direction of the guide support rods 111 is perpendicular to the side wall of the PCB mounting base plate 140.

[0038] It is understood that the number of guide support rods 111 can be four, or any other number, such as six, and the number of guide support rods 111 should not be construed as limiting the present application. The number of through holes 141 of the PCB mounting base 140 can be the same as the number of guide support rods 111, and the specific number of through holes 141 should not be construed as limiting the present application.

[0039] The PCB mounting base plate 140 is configured to slide relative to the tester housing 110 along the extension direction of the guide support rod 111. Optionally, a linear bearing 150 is provided between the through-hole 141 and the guide support rod 111. The linear bearing 150 fits over the guide support rod 111. This linear bearing 150 reduces sliding resistance between the PCB mounting base plate 140 and the tester housing 110, extending the service life of the tester and reducing maintenance costs.

[0040] In another embodiment, the PCB mounting base 140 is rotatably connected to the machine housing 110. Specifically, one side of the PCB mounting base 140 can be connected to the machine housing 110 via a hinge (not shown). The side of the PCB mounting base 140 away from the hinge is connected to the machine housing 110 via a snap fastener (not shown).

[0041] Optionally, the side of the PCB mounting base 140 connected to the machine housing 110 through a hinge can be any side of the rectangular PCB mounting base 140, and the side of the PCB mounting base 140 where the buckle is set can be opposite to the side where the hinge is set. For example, if the side where the hinge is set is the lower side of the PCB mounting base 140, then the side where the buckle is set is the upper side of the PCB mounting base 140; if the side where the hinge is set is the left side of the PCB mounting base 140, then the side where the buckle is set is the right side of the PCB mounting base 140.

[0042] One side of the PCB mounting base 140 is hinged to the machine housing 110. The side of the PCB mounting base 140 away from the hinge can be connected to the machine housing 110 via a snap-fit ​​connection. This snap-fit ​​connection facilitates connecting and disconnecting the PCB mounting base 140 from the machine housing 110, further enhancing the ease of movable connection between the PCB mounting base 140 and the machine housing 110.

[0043] Optionally, the PCB mounting base 140 and the machine housing 110 can be movably connected by a sliding connection or a rotating connection. The specific connection method between the PCB mounting base 140 and the machine housing 110 should not be understood as a limitation to this application.

[0044] The test machine provided in the embodiment of the present application may further include a bracket 160 and a rotating mechanism 170 , and the machine housing 110 and the bracket 160 are rotatably connected via the rotating mechanism 170 .

[0045] The bracket 160 may be an inverted T-shaped bracket 160 , with rollers provided at the bottom end of the bracket 160 to improve the mobility of the test platform, and a rotating mechanism 170 provided at the top end of the bracket 160 . The two sides of the platform housing 110 may be adapted to fit the top ends of the two inverted T-shaped brackets 160 .

[0046] The rotating mechanism 170 includes a rotating shaft 171, a plurality of bearings 172 that cooperate with the rotating shaft 171, a rotating positioning plate 173, and a knob plunger 174. For details, see Figure 2 The rotating shaft 171 can be fixedly connected to the machine housing 110. The multiple bearings 172 are all provided on the bracket 160. The machine housing 110 and the bracket 160 are rotatably connected through the cooperation between the rotating shaft 171 and the multiple bearings 172. Each of the multiple bearings 172 can be a deep groove ball bearing 172.

[0047] The rotation positioning plate 173 is fixedly connected to the machine housing 110 . The rotation positioning plate 173 is provided with a plurality of positioning holes 1731 . The knob plunger 174 cooperates with the plurality of positioning holes 1731 to limit the machine housing 110 to various angles.

[0048] When the knob plunger 174 is released, the machine housing 110 can rotate freely within one hundred and eighty degrees relative to the bracket 160 with the rotation axis 171 as the axis. The number of positioning holes 1731 can be specifically five. The knob plunger 174 cooperates with the five positioning holes 1731 to position the machine housing 110 together with the test machine in five working positions, including horizontal position, ±45°, ±90°, etc.

[0049] The working principle of the test machine provided in the embodiment of the present application is as follows:

[0050] The test circuit board 120 is fixedly installed within the machine housing 110. During testing, one end of the cable is fixedly connected to the second interface 121 of the test circuit board 120, while the other end of the cable needs to be moved between multiple first interfaces 131 on the PCB board 130. When a worker wishes to change the first interface 131 to which the cable is connected, they can first rotate the machine housing 110 relative to the bracket 160. When the machine housing 110 is rotated to the appropriate position, the worker can insert the knob plunger 174 into the corresponding positioning hole 1731, thereby fixing the test machine in a position convenient for the worker to operate. The worker only needs to adjust the limit by adjusting the knob plunger 174. This simple operation allows the operating position of the test machine to be freely adjusted, greatly satisfying the operator's operability when performing different processes.

[0051] Subsequently, when the staff wants to change the first interface 131 connected to the cable, they can move the PCB mounting base 140 relative to the machine housing 110, thereby increasing the operable space between the machine housing 110 and the PCB mounting base 140. This makes it easier for the staff to change the first interface 131 connected to the cable more quickly, reducing time and improving efficiency.

[0052] Optionally, if the PCB mounting base 140 is slidably connected to the machine housing 110, when the staff wants to change the first interface 131 connected to the cable, they can move the PCB mounting base 140 away from the machine housing 110 (such as Figure 4 The left side shown in the figure slides, thereby increasing the operable space between the PCB mounting base plate 140 and the machine housing 110, and the staff can easily and quickly change the first interface 131 for cable connection.

[0053] If the PCB mounting base 140 is rotatably connected to the machine housing 110, when a worker wants to change the first interface 131 for cable connection, the worker can rotate the PCB mounting base 140 away from the machine housing 110 about the rotation axis of the hinge, thereby increasing the operable space between the PCB mounting base 140 and the machine housing 110. The worker can then quickly and easily change the first interface 131 for cable connection.

[0054] The test machine provided in the embodiment of the present application can increase the operator's operating space when changing interfaces by flexibly connecting the PCB mounting base plate 140 to the machine housing 110. The flexibly connected connection can be a sliding connection or a rotating connection, allowing the operator to move the PCB mounting base plate 140 with relatively little effort. Compared with the existing technology, the test machine provided in the embodiment of the present application is simpler, more efficient, faster, and more labor-saving to operate, significantly reducing the preparation time for testers to change cable interfaces when frequent testing and verification are required.

[0055] In this document, relational terms such as first and second, etc. are used merely to distinguish one entity or operation from another entity or operation, but do not necessarily require or imply any actual relationship or order between these entities or operations.

[0056] The above description is merely an embodiment of the present application and is not intended to limit the scope of protection of the present application. For those skilled in the art, various modifications and variations of the present application are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
