Description

Technical Field

[0001] The utility model belongs to the technical field of filter debugging, and in particular relates to an automatic filter debugging machine. Background Art

[0002] There are many types of filters, each with different application frequency ranges and applications. Filters are constructed by coupling dielectric resonators. Dielectric resonator filters offer high Q, low insertion loss, compact size, and lightweight design, making them widely used in wireless base stations, satellite communications, navigation systems, and electronic countermeasures. Filters are formed using sintered ceramics and feature fine end-face patterns. To ensure quality, they undergo performance testing and visual inspection during the production process. Typically, the filter is manually placed on a test platform and manually adjusted using a grinding pestle based on experience. The filter is then electrically connected to an instrument that measures the filter's S parameters via a fixture, and the S-parameter curve on the display is used to determine if the filter has been properly adjusted. This entire process is inefficient, and manual placement of the filter can easily cause bumps and damage. Adjustment, which relies on operator experience, is also difficult to predict, resulting in low filter yield and inefficient production. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Since the existing technology is to manually use a grinding pestle to grind the silver paste layer of the filter based on experience, and then electrically connect the filter to the test instrument after grinding, and judge the grinding result by observing the S parameter curve, the manual judgment result is prone to errors, and manual grinding is not only inefficient but also easy to damage the filter, resulting in low efficiency, low yield, and poor debugging results.

[0032] Furthermore, the present application provides a debugging machine capable of automatically debugging a filter.

[0033] Example 1

[0034] Figure 1 This is a structural diagram of an automatic filter debugging machine provided in one embodiment of the present application.

[0035] Figure 2 This is a structural diagram of the loading platform of the utility model.

[0036] like Figures 1 to 2 As shown, this embodiment provides a filter automatic debugging machine, including:

[0037] The loading platform 10 is used to place the debugging filter. The two opposite edges of the loading platform are respectively provided with RF terminals 101. The upper surface of the loading platform is provided with a plurality of contacts 102. The plurality of contacts 102 are electrically connected to the RF terminals 101. The filter contacts the plurality of contacts 102 to form a path to obtain the debugging signal of the filter.

[0038] The limit block 12 is used to limit the filter. It is a semi-enclosed structure arranged around several contacts 102. It can be an L-shaped or C-shaped or other semi-enclosed structure. It limits the filter in the X-axis and Y-axis directions on the plane of the loading platform 10 so that the filter is always placed at the contact 102 position. The open side 121 of the semi-enclosed structure adapts to the shape of the filter and abuts against the filter.

[0039] The loading assembly includes a clamping jaw 14 and a first driving member 143 that drives the clamping jaw 14 to perform a clamping action. The loading assembly places the filter at the limit position of the limit block 12;

[0040] The unloading assembly is used to push the filter out of the loading platform 10 , and includes a unloading block 18 and a second driving member 181 for driving the unloading block 18 to move.

[0041] The working process of the filter automatic debugging machine provided in this application is as follows:

[0042] The loading assembly places the filter into the opening side 121 of the limit block 12. The end surface of the opening side 121 of the limit block 12 abuts against the filter, and the filter is limited in the X-axis and Y-axis directions on the plane of the loading platform 10. At this time, the filter contacts the contact 102 of the loading platform 10 to form a path, and the debugging signal of the filter is transmitted to the test instrument. The laser debugging machine automatically polishes the filter according to the debugging signal.

[0043] After the debugging is completed, the second driving member 181 drives the unloading block 18 to move in the opposite direction of the limit block 12 to push the filter out of the loading platform 10.

[0044] In this embodiment, the limit block 12 is fixedly set on the upper surface of the loading platform 10; and the height of the limit block 12 is lower than the thickness of the filter, so that a part of the filter is exposed from the limit block 12, making it convenient for the unloading block 18 to push the filter out of the loading platform 10 through the exposed part.

[0045] In this embodiment, the unloading block 18 is slidably disposed above the limiting block 12 , and the second driving member 181 drives the unloading block 18 to reciprocate along the limiting direction of the limiting block 12 to push out the filter.

[0046] This embodiment also includes a base, on which a loading platform 10 is mounted, height-adjustable via a number of screws. During production, the height of the loading platform 10 is adjusted by rotating the screws according to the desired test height. This allows the loading platform to accommodate filters of varying sizes and types, ensuring a suitable test location for both small integrated filters and large discrete component filters. This also facilitates future upgrades and expansions.

[0047] In this embodiment, the clamping jaw 14 includes a fixed clamping portion and a movable clamping portion, and the first driving member 143 drives the movable clamping portion to perform a clamping action; the first driving member 143 can be a linear reciprocating member such as a cylinder or a solenoid valve.

[0048] It also includes a displacement component 16, which is connected to the clamping jaw 14. The displacement component 16 includes an X-axis linear reciprocating motion mechanism 161 and / or a Y-axis linear reciprocating motion mechanism 162. During the production process, the X-axis linear reciprocating motion mechanism 161 and / or the Y-axis linear reciprocating motion mechanism 162 drive the clamping jaw 14 to move and adjust the operating position to adapt to different material clamping positions and placement positions. Specifically, the clamping jaw 14 clamps the filter and first places the filter to the absolute placement position on the X-axis or Y-axis of the limit block 12 through the X-axis linear reciprocating motion mechanism 161 or the Y-axis linear reciprocating motion mechanism 162. At this time, one side of the filter abuts against the opening side of the limit block 12; then, the filter is placed to the absolute placement position on the Y-axis or X-axis of the limit block 12 through the Y-axis linear reciprocating motion mechanism 162 or the X-axis linear reciprocating motion mechanism 161. At this time, the adjacent other side of the filter abuts against the other side of the opening of the limit block 12, completing the filter placement.

[0049] In this embodiment, the contact surfaces of the limiting block 12 and the unloading block 18 with the filter are made of insulating materials, such as plastic, rubber and other materials with good electrical properties.

[0050] In this embodiment, limit blocks are set around the contacts to limit the filter, ensuring the absolute placement of the filter; by setting loading components and unloading components, automatic loading and unloading of the filter can be achieved when limit blocks are set, thereby improving production yield and production efficiency.

[0051] Example 2

[0052] Figure 3 This is a structural diagram of an automatic filter debugging machine provided in another embodiment of the present application.

[0053] like Figure 3 As shown, in this embodiment, the unloading block 18 is rotatably arranged above the limit block 12, and the height of the limit block 12 is lower than the thickness of the filter. The second driving member 181 drives the unloading block 18 to rotate to push the filter out in the opposite direction of the limit direction of the limit block 12.

[0054] In this embodiment, the second driving member 181 is a stepper motor, which has high precision and can achieve very precise position control; it can also be a combination of a servo motor and a reducer, or other devices that can achieve precise position control during circular motion.

[0055] After debugging is completed, the second driving member 181 drives the unloading block 18 to rotate, and the unloading block 18 contacts the portion of the filter exposed from the limit block 12 and pushes the filter out in the opposite direction of the limit block 12 to complete the unloading action.

[0056] In this embodiment, the unloading block 18 is rotatably set above the limit block 12, and the original linear reciprocating motion unloading mechanism is converted into a circular motion mechanism. Compared with the original linear bidirectional motion, the unidirectional circular motion has higher accuracy and better durability after long-term use, which can effectively reduce equipment failures and improve production efficiency.

[0057] Example 3

[0058] Figure 4 This is a structural diagram of an automatic filter debugging machine provided in yet another embodiment of the present application.

[0059] like Figure 4 As shown, in this embodiment, the limit block 12 is set on the loading platform 10 by sliding a slider (not shown), and the loading platform 10 is provided with a slide groove 123 for allowing the limit block 12 to slide along its length direction, and also includes a third driving member 124 for driving the limit block 12 to slide; the third driving member 124 can be a linear reciprocating motion member such as a cylinder and a solenoid valve; when the slider is placed in the end position in the slide groove 123, the limit block 12 is just in the limit position surrounding the contact 102 on the loading platform 10.

[0060] After the debugging is completed, the third driving member 124 drives the limiting block 12 to move in the opposite direction of the limiting direction to push the filter out of the loading platform 10 .

[0061] In this embodiment, a slide groove 123 is provided on the loading platform 10, so that the limit block 12 slides on the loading platform 10 to push the filter out, thereby realizing the unloading function; at the same time, when the slider is placed in the end position in the slide groove 123, the limit block 12 is just in the limit position surrounding the contact 102 on the loading platform 10, which will not affect the original limit function of the limit block 12. Therefore, the structure is more streamlined.

[0062] Example 4

[0063] Figure 5 This is a structural diagram of an automatic filter debugging machine provided in yet another embodiment of the present application.

[0064] like Figure 5 As shown, in this embodiment, the device further includes a rotating connector 125, with a plurality of stoppers 12 equidistantly connected to its edge. The rotating connector 125 may be in the shape of a disk. The device further includes a fourth driving member 126 for driving the stoppers 12 to rotate. The fourth driving member 126 stops when it reaches a limit position of the stoppers 12. The fourth driving member 126 may be a stepper motor with a braking function, such as a brake stepper motor, specifically model Y07-58D1-4008M, which enables precise positioning and stopping during the production process.

[0065] During debugging, the fourth driving member 126 drives the rotating connecting member 125 to rotate, and drives the limit block 12 to rotate. The limit block 12 stops when it is at the side position around the contact 102. At this time, the clamping jaw 14 places the filter to the limit position on the opening side 121 of the limit block 12 for debugging; after debugging is completed, the fourth driving member 126 drives the rotating connecting member 125 to rotate, and drives the limit block 12 to rotate to push the filter out.

[0066] Compared with the third embodiment, this embodiment replaces the linear reciprocating motion drive mechanism with a circular motion drive mechanism. Compared with the original linear bidirectional motion, the unidirectional circular motion has higher accuracy and better durability during long-term use; it avoids opening a slide groove 123 on the loading platform 10, thereby improving the overall structural performance; the limit block 12 and the fourth drive member 126 are separated from the loading platform 10, with a higher degree of modularity and easy maintenance and replacement.

[0067] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
