Description

Technical Field

[0001] The present invention relates to the field of millimeter wave communication technology, and in particular to a millimeter wave anti-interference test fixture and a test tooling assembly. Background Art

[0002] During the production process of electronic devices such as wearable watches, wireless millimeter wave modules need to be tested for connectivity and disconnection functions on a test fixture before being assembled inside them. Only after the test is passed can they be assembled inside the wearable watch, which can greatly improve the yield rate of the wearable watch.

[0003] For example, when testing the on-off function of the SIP millimeter wave module inside a wearable watch, the magnetic seat with the DOCK millimeter wave module is fixed at the specified position of the fixture. During the signal connection and disconnection test between the two, it is necessary to open a signal channel in the area between the two in the test fixture in advance, and control the disconnection and connection of the signal between the two millimeter wave modules by adding a metal stopper with an automatic switch in the channel. However, the aperture of the signal channel of the existing fixture is large, and the metal stopper cannot completely seal the signal channel. Based on the scattering and reflection characteristics of the millimeter wave module propagating in the air, when the metal stopper is inserted into the signal channel, the metal stopper cannot completely isolate the signal channel, causing the signal of the millimeter wave module to pass through the gap between the metal stopper and the signal channel during the test, thereby failing to completely disconnect the two millimeter wave signals. In addition, the millimeter wave signal in the channel will escape to the outside through the gap between the metal stopper and the signal channel, which can easily cause the millimeter wave signal to interfere with each other between multiple adjacent signal channels, affecting the test results.

[0004] Therefore, how to improve the technical defects existing in the prior art has always been a problem that ordinary technicians in this field need to solve urgently. Summary of the invention

[0055] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0056] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0057] According to a specific embodiment provided by the present invention, Figures 1 to 7As shown, the present invention provides a millimeter wave anti-interference test fixture in the first aspect, which may specifically include an upper carrier 1, a lower carrier 2 and a switch assembly 3. The lower carrier 2 is used to load the SIP millimeter wave module, and the upper carrier 1 is buckled with the upper carrier 2. The switch assembly 3 is installed on the upper carrier 1, and may specifically include a metal body 31, a metal baffle 32 and a power part 33. The DOCK millimeter wave module is loaded on a magnetic base 4, and the DOCK millimeter wave module is provided with a signal transmission belt 5 extending outside the magnetic base 4 and a detection port 6 provided at one end of the signal transmission belt 5. The metal body 31 is provided with a transmission channel 311, and the detection port 6 of the DOCK millimeter wave module and the detection port of the SIP millimeter wave module are connected through the transmission channel 311. And the metal body 31 is provided with a slideway 312 connected to the transmission channel 311. The power member 33 is used to drive the metal baffle 32 to slide back and forth along the slideway 312 , so that the metal baffle 32 closes or opens the transmission channel 311 , thereby realizing the connection or disconnection of signals between the SIP millimeter wave module and the DOCK millimeter wave module.

[0058] In this embodiment, the staff only needs to directly load the DOCK millimeter wave module onto the magnetic base 4, and directly load the SIP millimeter wave module onto the lower fixture 2, so that the detection ports of the two millimeter wave modules can be directly aligned with the upper and lower openings 3114 of the transmission channel 311, and the upper and lower openings 3114 of the transmission channel 311 can be closed. The staff can directly operate the switch assembly 3 to test the short-distance point-to-point signals of the two millimeter wave modules. The test fixture provides an efficient power supply and a high data rate wireless link, so that the millimeter wave signal can be tested without providing physical cables and connectors, which greatly simplifies the test steps and improves the accuracy of the test. This patent uses a power part 33 to drive the metal baffle 32 to slide back and forth along the slide 312. When the metal baffle 32 enters the transmission channel 311, the metal baffle 32 will separate the transmission channel 311 into two parts, and the two parts are completely closed and isolated under the action of the metal baffle 32, and there will be no local gap, which can effectively prevent the signal of the millimeter wave module from passing through the gap, and then the two millimeter wave module signals can be completely disconnected. In addition, the complete closure of the transmission channel 311 can also effectively prevent the millimeter wave signal inside it from escaping to the outside world, thereby interfering with the remaining adjacent transmission channels 311, and can effectively ensure that multiple adjacent transmission channels 311 do not interfere with each other, thereby greatly improving the efficiency and accuracy of the test and reducing the retest rate.

[0059] Preferably, in this embodiment, the upper carrier 1 and the lower carrier 2 of the test fixture may be preferably arranged in a square block structure with consistent contours, and the contacting end of the two is arranged in a plane, so that the two can be tightly fastened without any gap, thereby greatly improving the accuracy of the test.

[0060] Specifically, see Figure 1 and Figure 2 , the lower tool 2 is provided with a receiving groove 21 for placing the SIP millimeter wave module. This embodiment does not impose any restrictions on the specific structure of the receiving groove 21. It only needs to ensure that it can adapt to the contour of the SIP millimeter wave module, and no excessive restrictions are imposed here. Among them, when the SIP millimeter wave module is placed in the receiving groove 21, the upper end surface of the SIP millimeter wave module can preferably be recessed in the receiving groove 21. In this way, when the upper carrier 1 abuts against the notch of the receiving groove 21, that is, the upper end surface of the lower tool 2, the SIP millimeter wave module can be completely locked in the receiving groove 21, thereby effectively ensuring that the SIP millimeter wave module will not move in position during the test process, thereby greatly improving the stability of the test. Of course, the upper end surface of the SIP millimeter wave module can also be set flush with the notch of the receiving groove 21, that is, as long as it can be ensured that the upper carrier 1 and the lower tool 2 can fit tightly and there is no gap at the connection between the two, it is all within the scope of protection of this patent and will not be described in detail here.

[0061] It is worth mentioning that in order to effectively ensure that the upper carrier 1 and the lower carrier 2 do not move laterally due to external force after being fitted, it is preferred to set a plurality of protrusions and grooves of one type on the peripheral edge of the upper end surface of the upper carrier 1, and correspondingly, it is preferred to set another type of protrusions and grooves of the same number and position at the corresponding position of the lower end surface of the lower carrier 2. Through the limited cooperation of the protrusions and grooves, and by utilizing the gravity of the upper carrier 1 itself, the upper carrier 1 and the lower carrier 2 can be tightly fastened, thereby effectively preventing the lateral movement between the two, and thus greatly improving the accuracy of the millimeter wave module test. Of course, the plurality of protrusions and grooves can also be replaced by annular protrusions and annular grooves surrounding the peripheral edge of the upper carrier 1 or the lower carrier 2, all of which are within the scope of protection of this patent and will not be described in detail here.

[0062] Further, in this embodiment, continue to refer to Figure 1 and Figure 2, the metal body 31 can be preferably located on the side of the upper carrier 1 facing away from the lower carrier 2, and the transmission channel 311 is connected to the upper and lower end surfaces of the metal body 31. Among them, the magnetic seat 4 for loading the DOCK millimeter wave module can be operably placed on the end of the metal body 31 away from the upper carrier 1, and the detection port 6 of the DOCK millimeter wave module extends to the outside of the magnetic seat 4 through the signal transmission belt 5, and is operably placed in the upper opening 3113 of the transmission channel 311. And the upper carrier 1 is provided with a through hole 11 connected to the transmission channel 311 at the position corresponding to the detection port of the SIP millimeter wave module. The caliber of the through hole 11 is consistent with the transmission channel 311. In this way, when the SIP millimeter wave module is placed in the accommodating groove 21, its detection port is set corresponding to the lower opening 3114 of the detection transmission channel 311, that is, it is located directly below the through hole 11. The through hole 11 can form an integral channel with the transmission channel 311, and act together on the detection ports of the two millimeter wave modules. The above structural mode is not only conducive to the rapid assembly of the test fixture, but also can greatly improve the precision of the test and reduce the retest rate.

[0063] It is worth mentioning that in this embodiment, in order to improve the accuracy of the test, after repeated tests, when the vertical distance between the detection port 6 of the DOCK millimeter wave module and the detection port of the SIP millimeter wave module is 20 mm, the accuracy of the tests of both is the highest. Therefore, as a preferred embodiment, when the DOCK millimeter wave module and the SIP millimeter wave module are respectively loaded on the magnetic base 4 and the lower tool 2, the distance between the detection port 6 of the DOCK millimeter wave module and the detection port of the SIP millimeter wave module is 20 mm. In other words, the length of the overall channel formed by the through hole 11 and the transmission channel 311 is 20 mm.

[0064] It is worth mentioning that in this embodiment, the transverse cross-section of the transmission channel 311 may be square, and is preferably opened at a middle position adjacent to the metal body 31 , but is not limited thereto.

[0065] Furthermore, since aluminum has good signal shielding performance, the metal body 31 can be preferably made of aluminum to form signal shielding for the peripheral edges of the transmission channel 311. Of course, the metal body 31 can also be made of other metal materials with signal shielding function, which are all within the protection scope of this patent and are not specifically limited here, and can be flexibly selected according to actual use needs.

[0066] In this embodiment, see Figures 3 to 6 It is preferred that a slideway 312 connected to the transmission channel 311 is opened on the side of the metal body 31, and the power part 33 is used to drive the metal baffle 32 to slide back and forth along the slideway 312, so as to realize the connection and closure of the transmission channel 311 through the metal baffle 32, thereby realizing the complete disconnection and connection of the signals of the two millimeter wave modules.

[0067] Specifically, the slideway 312 may preferably be opened at a position of the metal body 31 adjacent to the upper carrier 1, and the metal baffle 32 and the slideway 312 have matching contours. The slideway 312 separates the transmission channel 311 into a first channel 3111 and a second channel 3112. The upper opening 3113 of the first channel 3111 is connected to the detection port 6 of the DOCK millimeter wave module, and the lower opening 3114 of the second channel 3112 is connected to the detection port of the SIP millimeter wave module. When the metal baffle 32 closes the transmission channel 311, the upper opening 3113 of the first channel 3111 is closed by the detection port 6 of the DOCK millimeter wave module, the lower opening 3114 of the first channel 3111 is closed by the upper end surface of the metal baffle 32, and the lower opening 3114 of the second channel 3112 is closed by the detection port of the SIP millimeter wave module, and the upper opening 3113 of the second channel 3112 is closed by the lower end surface of the metal baffle 32. In this way, under the action of the metal baffle 32, the first channel 3111 and the second channel 3112 can be completely closed and isolated on the metal baffle 32 without any local gap, thereby effectively preventing the signals of the two millimeter wave modules from passing through the gap, thereby effectively avoiding the probability of receiving local signals between the two millimeter wave modules, and then completely disconnecting the signals of the two millimeter wave modules, greatly reducing the retest rate.

[0068] Preferably, the opening of the transmission channel 311 corresponding to the position of the slide 312 should fall within the range of the slide 312, so as to ensure that the end face of the metal baffle 32 can completely cover the transmission channel 311, thereby eliminating the gap between the metal baffle 32 and the transmission channel 311, and further effectively sealing the signal inside the transmission channel 311 to prevent it from escaping to the outside.

[0069] It is worth mentioning that the metal baffle 32 can also be made of aluminum material to shield the signal inside the transmission channel 311. Of course, the metal baffle 32 can also be made of other metal materials with signal shielding function, which are all within the protection scope of this patent and are not specifically limited here. It can be flexibly selected according to actual use needs.

[0070] Furthermore, in this embodiment, in order to improve the stability of the metal baffle 32 during its movement along the slide 312, the metal body 31 is further provided with a receiving station 313 connected to the slide 312. The longitudinal cross-sections of the receiving station 313 and the slide 312 may be L-shaped, and the receiving station 313 and the slide 312 both penetrate the opposite end surfaces of the metal body 31. Figure 7, the metal baffle 32 can be installed on the power member 33 through a connecting member 34. The contour of the connecting member 34 can be adapted to the accommodating station 313. The power member 33 is used to drive the connecting member 34 to slide back and forth along the accommodating station 313, thereby driving the metal baffle 32 to slide back and forth along the slideway 312. In this embodiment, driven by the connecting member 34, the movement of the metal baffle 32 can be smoother, thereby improving the stability of the test. It is worth mentioning that the connecting member 34 can preferably be integrally formed with the metal baffle 32, but is not limited to this. It is also worth mentioning that the power member 33 can preferably be an electric cylinder or a pneumatic cylinder or a servo motor, all of which are within the protection scope of this patent.

[0071] Furthermore, compared with the existing fixtures, the test fixture provided by the present invention improves the anti-interference performance by more than 10% and the continuity by more than 70% when testing the DOCK millimeter wave module and the SIP millimeter wave module.

[0072] Of course, the present invention also provides a test tool assembly in the second aspect, which may specifically include an installation panel, a controller and the millimeter wave anti-interference test fixture provided in the first aspect of the present invention. Specifically, a plurality of millimeter wave anti-interference test fixtures are evenly distributed on the installation panel, and the spacing between each two adjacent millimeter wave anti-interference test fixtures is equal. The controller is used to drive a plurality of power parts 33 to operate synchronously, so as to perform synchronous testing on the DOCK millimeter wave module and the SIP millimeter wave module assembled on each millimeter wave anti-interference test fixture, which can greatly improve the test efficiency. In addition, the complete closure of the transmission channel 311 can also effectively prevent the millimeter wave signal inside it from escaping to the outside world, thereby interfering with the transmission channels 311 of the remaining adjacent test fixtures, and can effectively ensure that multiple adjacent transmission channels 311 do not interfere with each other, thereby greatly improving the efficiency and accuracy of the test and reducing the retest rate.

[0073] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
