TECHNICAL FIELD
[0001] The present application relates to the technical field of detection, in particular to a detection device. BACKGROUND
[0002] In a material (or product) production or test operation, the material needs to be placed on the carrier plate of a fixture, and then moved to the operation position by the carrier plate. At the operation position, the pressing plate of the fixture is pressed towards the carrier plate to perform the production or test operation. However, due to the production tolerance of the fixture or the matching tolerance between the fixture and the material, the material may be lifted by the pressing plate when the pressing plate is lifted, which may affect the subsequent operation.
[0003] Although the lifting of the material by the pressing plate may produce an abnormal sound, manual listening and observation may have low detection efficiency and may miss or misjudge the detection. CONTENT OF THE UTILITY MODEL
[0004] Therefore, the present application provides a detection device to detect whether the relative position between the material and the fixture in the production or test operation meets the standard, and to improve the detection accuracy.
[0005] An embodiment of the present application provides a detection device for detecting the relative position of a first structure and a second structure. The first structure is movable along a first direction. The detection device comprises a test table, a first sensing module and a second sensing module. The test table has a first region, a second region and a third region arranged in sequence along the first direction, and the first region, the second region and the third region are all on the movement path of the first structure along the first direction. The first sensing module is arranged on the test table. The first sensing module comprises a first sensing member and a second sensing member. The first sensing member is used for sensing the first structure in the first region. The second sensing member is used for sensing the first structure in the third region. The second sensing module is arranged on the test table. The second sensing module comprises a third sensing member. The third sensing member is used for sensing the first structure and / or the second structure in the second region.
[0006] In the production operation or the test operation, the second structure is a carrier plate carrying the material or the material itself, and the first structure is a pressing plate pressing the second structure. The moving path of the first structure and the second structure is usually determined or preset. In the above embodiment, a detection device for detecting the relative position of the first structure and the second structure is provided. The test platform has a first area, a second area and a third area corresponding to the moving path of the first structure in the first direction. The first sensing module can sense whether the first structure is located in the first area or the third area when the first structure moves between the first area and the third area. The second sensing module can sense whether the first structure and / or the second structure is in the second area. When the first structure and / or the second structure is sensed in the second area, it indicates that the first structure is lifted and the second structure is brought up, so that the second structure is in the wrong position, which may cause damage to the material or the carrier plate carrying the material in the subsequent operation. Therefore, the first structure and the second structure in the production operation or the test operation can be detected in time and effectively, the possibility of missed detection or false detection is reduced, and the risk of damage to the second structure is reduced.
[0007] In some embodiments of the present application, the first sensing module further comprises a first fixed support. The first fixed support is mounted on the test platform. The first sensing member is connected to the first fixed support. The first sensing member is arranged on the side of the first fixed support facing the first area, so that the first sensing member can sense the first structure in the first area. The second sensing member is connected to the first fixed support. The second sensing member is arranged on the side of the first fixed support facing the third area, so that the second sensing member can sense the first structure in the third area. The second sensing module further comprises a second fixed support. The second fixed support is mounted on the test platform. The third sensing member is connected to the second fixed support. The third sensing member is arranged on the side of the second fixed support facing the second area, so that the third sensing member can sense the first structure and / or the second structure in the second area.
[0008] In the above embodiment, the first fixed support and the second fixed support are arranged on the test platform. The first fixed support is used to mount the first sensing member and the second sensing member of the first sensing module, and the second fixed support is used to mount the third sensing member. Through the first fixed support and the second fixed support, each sensing member can be in the correct position for stable detection.
[0009] In some embodiments of the present application, the third sensing member is a photoelectric linear sensor. The light path emitted by the third sensing member has a first included angle with the first direction, and the first included angle is greater than 0° and less than 90°.
[0010] In the above embodiment, the third sensing member is a photoelectric linear sensor, and the light path emitted by the third sensing member has a first included angle with the first direction, and the first included angle is an acute angle. During the production operation or the test operation, when the first structure member is lifted to return to the third region after being pressed, if the second structure member is lifted by the first structure member, the first structure member and the second structure member will at least partially contact each other, so that the light path emitted by the third sensing member is blocked, or the gap between the first structure member and the second structure member cannot allow the light path emitted by the third sensing member to pass through, so that it is detected that the second region has the first structure member and / or the second structure member, that is, the second structure member is lifted or the first structure member does not return to the third region.
[0011] In some embodiments of the present application, the first fixed support is provided with a connecting groove extending along the first direction. The first sensing member and the second sensing member are detachably connected to the connecting groove on the first fixed support, so that the first sensing member and the second sensing member can be adjusted in position on the first fixed support along the first direction.
[0012] In the above embodiment, the connecting groove extending along the first direction is formed on the first fixed support, so that the first sensing member and the second sensing member can be adjusted in position for different specifications of the first structure member and the second structure member, so as to improve the accuracy of detection.
[0013] In some embodiments of the present application, the test table is provided with a first channel in a direction perpendicular to the first direction. The first fixed support is detachably connected to the first channel, so that the first sensing module can be adjusted in position along the extension direction of the first channel.
[0014] In the above embodiment, the first channel is arranged on the test table in a direction perpendicular to the first direction, which facilitates the adjustment of the position of the first sensing module, so that the positions of the first sensing member and the second sensing member in the extension direction of the first channel can also be adjusted, and the applicability of the detection device is further improved.
[0015] In some embodiments of the present application, the first sensing module further comprises two first fixed blocks. The first fixed block has a first mounting surface and a second mounting surface perpendicular to each other. The first mounting surfaces of the two first fixed blocks are connected with the connecting groove of the first fixed support. When the detection device detects the relative position of the first structure member and the second structure member, the second mounting surface is parallel to the horizontal plane. The first sensing member is placed on the second mounting surface of one first fixed block, and the second sensing member is placed on the second mounting surface of the other first fixed block.
[0016] In the above embodiment, two first fixed blocks are mounted on the first fixed support and used for placing the first sensing member and the second sensing member, respectively. The first fixed block has a second mounting surface parallel to the horizontal plane, and the first sensing member and the second sensing member can be directly placed on the second mounting surface, so as to ensure the mechanical stability of the first sensing member and the second sensing member, and thus ensure the detection accuracy.
[0017] In some embodiments of the present application, the second fixing support is provided with a connecting groove extending along the first direction, and the third sensing member is detachably connected to the connecting groove on the second fixing support, so that the third sensing member can be adjusted in position on the second fixing support along the first direction.
[0018] In the above embodiment, the connecting groove extending along the first direction is formed on the second fixing support, so that the third sensing member can be adjusted in position for different specifications of the first structural member and the second structural member to achieve the best detection effect.
[0019] In some embodiments of the present application, the test bench is provided with a second channel along a direction perpendicular to the first direction. The second fixing support is detachably connected to the second channel, so that the second sensing module can be adjusted in position along the extension direction of the second channel.
[0020] In the above embodiment, the second channel along the direction perpendicular to the first direction is arranged on the test bench, which facilitates the adjustment of the position of the second sensing module, so that the position of the third sensing member in the extension direction of the first channel can also be adjusted, further improving the applicability of the detection device.
[0021] In some embodiments of the present application, the second sensing module further comprises a second fixing block. The second fixing block has a third mounting surface and a fourth mounting surface. The third mounting surface is connected to the connecting groove of the second fixing support. The fourth mounting surface has a second included angle with the first direction, and the second included angle is greater than 0° and less than 90°.
[0022] In the above embodiment, when the first structural member lifts up the second structural member, the inclination angle of the second structural member relative to the first direction will change. The third sensing member is mounted to the second fixing support through the second fixing block, and the fourth mounting surface of the second fixing block has a second included angle with the first direction. According to the actual situation, the second included angle is set to make the third sensing member detect the lifted second structural member.

The area between the first sensing module and the second sensing module on the test table is used to set the first structural member and the second structural member related jig, and the first sensing module and the second sensing module are oppositely arranged, and the adjustability of the two on the test table is also higher.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs.

[0038] The embodiments of the present application provide a detection device for detecting the relative position of a first structural member and a second structural member. The first structural member is movable along a first direction. The detection device comprises a test table, a first sensing module and a second sensing module. The test table has a first region, a second region and a third region arranged in sequence along the first direction, and the first region, the second region and the third region are all on the movement path of the first structural member along the first direction. The first sensing module is provided on the test table. The first sensing module comprises a first sensing member and a second sensing member. The first sensing member is used for sensing the first structural member in the first region. The second sensing member is used for sensing the first structural member in the third region. The second sensing module is provided on the test table. The second sensing module comprises a third sensing member. The third sensing member is used for sensing the first structural member and / or the second structural member in the second region.
[0039] In a production operation or a test operation, the second structure is a material or a carrier plate carrying the material, and the first structure is a pressing plate pressing the second structure.

In this way, the first structure and the second structure in the production operation or the test operation can be detected in time and effectively, the possibility of missed detection or false detection is reduced, and the risk of damage to the second structure is reduced.
[0040] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.
[0041] Referring to Figure 1 An embodiment of the present application provides a detection device 100 for detecting the relative position of a first structure (not shown in the figure) and a second structure (not shown in the figure).
[0042] The first structure can move in a first direction Z, and the second structure can move in a second direction X. In some embodiments, the first structure moves in the first direction Z, which corresponds to the vertical upward movement of the first structure to complete the lifting action. The second structure moves in the second direction X, which corresponds to the feeding of the second structure. The direction opposite to the second direction X is the unloading of the second structure. The detection device 100 includes a test table 4, a first sensing module 1 and a second sensing module 2. The test table 4 has a first area, a second area and a third area arranged in sequence along the first direction Z, and the first area, the second area and the third area are all on the moving path of the first structure in the first direction Z.

[0043] In the production operation or the test operation, the second structure is a carrier plate carrying the material or the material itself, and the first structure is a pressing plate pressing the second structure. The moving path of the first structure and the second structure is usually determined or preset. In the above embodiment, a detection device 100 for detecting the relative position of the first structure and the second structure is provided. The test table 4 has a first area, a second area and a third area corresponding to the moving path of the first structure in the first direction Z. The first sensing module 1 can sense whether the first structure is located in the first area or the third area when the first structure moves between the first area and the third area. The second sensing module 2 can sense whether the first structure and / or the second structure is in the second area. When the first structure and / or the second structure is sensed in the second area, it indicates that the first structure is lifted and the second structure is brought up, so that the second structure is in the wrong position, which may cause damage to the material or the carrier plate carrying the material in the future. Therefore, the first structure and the second structure in the production operation or the test operation can be detected in time and effectively, the possibility of missed detection or false detection is reduced, and the risk of damage to the second structure is reduced.

In this way, the applicability of the detection device 100 is further improved.
[0066] In some embodiments, the first fixing support 13, the second fixing support 22 and the third fixing support 32 can have the same structure, and the connecting grooves 5 provided in each of them can also be the same.
[0067] In some embodiments, the detection device 100 further comprises a warning module (not shown in the figure). When the detection device 100 detects the relative position of the first structure and the second structure, if the time corresponding to each action of the first structure and / or the second structure does not meet the preset time, or if the third sensing member 21 senses the first structure and / or the second structure in the second area, it is determined that the first structure and / or the second structure is abnormal, and then an alarm is given to the user.
[0068] Taking a radio frequency test fixture as an example, electronic components such as a mainboard are placed on the carrier plate of the radio frequency test fixture for testing and verification of the mainboard. When the test fixture is working, there are actions of in-out operation and up-down operation. The in-out operation specifically refers to placing the workpiece to be tested on the carrier plate, and the linear slide rail assembly of the test fixture drives the carrier plate and the workpiece to be tested to enter and exit the test fixture. The up-down operation specifically refers to that in order to ensure the strength of electrical connection during testing, the upper pressing plate of the test fixture will press the workpiece to be tested; after the test is completed, the upper pressing plate will be popped up to disconnect. Therefore, the first structure corresponds to the upper pressing plate, and the second structure corresponds to the mainboard and / or the carrier plate; the first direction Z is the direction of movement of the upper pressing plate when it is popped up, which is generally vertical upward; the second direction X is the direction of the carrier plate entering the fixture, i.e. the direction of feeding.
[0069] Understandably, the in-out pressing action flow of the radio frequency test fixture has strict requirements, and the required time is fixed, so the control program is designed according to this flow, which can specifically use the flag bit mode, the current state of the test fixture and the action of the last step correspond to an independent flag bit, and the next action is performed according to the flag bit. The verification test process of a workpiece to be tested in the radio frequency test fixture includes feeding, testing and discharging. The fourth sensing element 31 senses the carrier plate twice in the fourth area. The two sensing corresponds to the upper limit time and the lower limit time of the entire verification test process. The first sensing element 11 senses the upper pressing plate in the first area, and the second sensing element 12 senses the upper pressing plate in the third area. The time required for the lifting action of the upper pressing plate corresponds to the time required for the lifting action of the upper pressing plate between the two flag bits; in turn, it is the pressing action of the upper pressing plate. After the upper pressing plate is lifted, the second sensing element 12 senses the upper pressing plate in the third area. At this time, if the third sensing element 21 senses the carrier plate in the second area, that is, the carrier plate is lifted, that is, the carrier plate is clamped. When the detection device 100 detects that the time between each action corresponding to the flag bit does not meet the preset time, or the third sensing element 21 senses the carrier plate in the second area, it is determined that the radio frequency test fixture is abnormal, and the warning module will alarm to prompt the user.

Any appropriate changes and variations to the above embodiments within the spirit and principles of the present application fall within the scope of the present application.
