Description

Technical Field

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

[0002] In the field of electronics, filters, as key electronic components, are widely used in communications, signal processing, control systems, and other applications. The stability and accuracy of their performance are directly related to the overall performance of the electronic system. After production, filters undergo a rigorous debugging process to ensure that key specifications such as frequency response, insertion loss, and out-of-band rejection meet design requirements. Traditionally, filter debugging relies on manual operation, requiring filters to be manually placed on a debugging platform one by one, and then the debugging equipment is activated for testing.

[0003] However, this manual operation method has many drawbacks. First, manual filter placement is not only inefficient but also prone to inaccurate placement due to fatigue or negligence, which in turn affects the accuracy and consistency of debugging results. Second, to ensure the filter is correctly placed, operators need to conduct a secondary inspection after placement, which undoubtedly adds additional labor hours and costs. Furthermore, with the expansion of filter production scale and the increasing debugging requirements, manual operation can no longer meet the needs of efficient and precise production.

[0004] To overcome the shortcomings of traditional manual filter commissioning machines, a number of improved commissioning devices have emerged on the market, attempting to improve commissioning efficiency and accuracy through automation. However, these devices often only enable automatic filter delivery, requiring additional inspection steps or manual intervention to confirm correct filter placement. This not only increases the complexity of the equipment but also fails to fundamentally address the efficiency and accuracy issues inherent in manual operation.

[0005] In view of the above background, the utility model proposes an automatic feeding filter debugging machine, which aims to realize automatic screening and feeding of filters through innovative automation technology. Utility Model Content

[0012] The material return mechanism includes a driving component for receiving an action instruction and driving the output end to perform a corresponding action, so as to push out the medium blocks that do not meet the conditional characteristics and drop them into the vibration plate.

DETAILED DESCRIPTION

[0029] 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.

[0030] During the filter manufacturing process, the debugging of S parameters (scattering parameters) is a key step to ensure that the filter performance meets the design requirements. S parameters describe the transmission and reflection characteristics between the filter ports, and have a direct impact on the key performance indicators of the filter, such as the frequency response, insertion loss, and return loss. Since the filter may be affected by slight differences in materials, processes or environmental factors during the production process, causing the S parameters to deviate from the design standards, thereby affecting the overall performance of the filter, a filter debugging machine is usually required to polish the metal layer on the surface of the filter to meet the design parameters. In the prior art, it is necessary to manually place the filter on the debugging platform, and the operator is required to observe with the naked eye whether the filter is placed correctly. The filter specifications are small and not convenient for naked eye observation. Long-term operation can easily lead to inaccurate placement due to fatigue or negligence, thereby affecting the accuracy and consistency of the debugging results.

[0031] Furthermore, the present application provides a filter debugging machine capable of automatic loading.

[0032] Figures 1 to 2 This is a schematic diagram of the structure of the filter provided in this embodiment.

[0033] like Figures 1 to 2 As shown, the filter includes a dielectric block 20, which includes an open surface 201 and a short-circuit surface 202 arranged opposite to each other, and an electrode surface 203 arranged adjacent to one of the open surface 201 and the short-circuit surface 202. The dielectric block 20 is made of a dielectric material, and the open surface 201, the short-circuit surface 202, and the electrode surface 203 are all made of a conductive material. The content of conductive material on each surface of the dielectric block 20 is different, and therefore, the ratio of conductive material to dielectric material on each surface of the dielectric block 20 is different. By identifying the material content on different surfaces, the placement surface of the dielectric block 20 is determined.

[0034] Example 1

[0035] Figure 3 The utility model is a structural diagram of an automatic feeding filter debugging machine.

[0036] Figure 4 For this utility model Figure 3 A magnified schematic diagram of the structure at point A in the middle.

[0037] like Figures 3 and 4 The automatic loading filter debugging machine shown is used for debugging the filter, comprising:

[0038] The vibration feeding mechanism 10 includes a vibration disk 101 and an exciter 102 that drives the vibration disk 101 to vibrate in a specific direction to feed the material. The vibration disk 101 is circular, and the central protrusion transitions to the edge in an arc. In this embodiment, the exciter adopts a common electromagnetic exciter 102 to provide feeding power through excitation. The excitation disk is circular, and the central protrusion transitions to the edge in an arc, which facilitates the even spreading of the filter toward the edge and prevents some filters from getting stuck on the surface of the vibration disk 101.

[0039] The spiral track 12 is connected to the vibrating feeding mechanism 10 and is spirally arranged on the circumference of the vibrating disk 101 . The spiral diameter gradually increases upward and a U-shaped track groove 121 is opened on the track. The U-shaped track groove 121 is adapted to the shape of the dielectric block 20 .

[0040] The screening assembly 13 is used to confirm that the surface of the media block 20 is oriented correctly for transport and debugging. It includes a plurality of identification units 14 arranged around the spiral track 12. The identification units 14 identify the material content on the surface of the media block 20 and send identification information. It also includes:

[0041] a controller (not shown), configured to receive identification information from the identification unit 14 and output an action instruction according to the identification information;

[0042] The material return mechanism (not shown) includes a drive member (not shown) for receiving an action command and performing a corresponding action to push out the medium blocks 20 that do not meet the conditional characteristics and drop them into the vibrating plate 101. In this embodiment, the spiral track 12 provided on the side of the vibrating plate 101 facilitates material return. The medium blocks 20 only need to be pushed toward the inside of the spiral track 12 to fall into the vibrating plate 101 for re-screening, which takes up less space and improves space utilization.

[0043] The working process of the automatic feeding filter debugging machine provided by this application is as follows:

[0044] A plurality of dielectric blocks 20 to be debugged are placed in the vibration disk 101. The vibrator 102 vibrates in a specific direction to send the dielectric blocks 20 into the spiral track 12. The dielectric blocks 20 are arranged in sequence in the U-shaped track groove 121 and are pushed through the U-shaped track groove 121 in sequence by the excitation force. During this process, the identification unit 14 on one side of the spiral track 12 identifies the dielectric blocks 20 and determines whether the current position of the dielectric blocks 20 is correct based on the different material contents on the surfaces of the dielectric blocks 20. When the identification unit 14 identifies that the material content parameters on the surface of the dielectric blocks 20 are different from the preset parameters in the controller, the controller outputs the material return mechanism to push the dielectric blocks 20 out and drop them into the vibration disk 101 for further screening.

[0045] The present application drives the vibration disk 101 to feed the spiral track 12 by vibrating the exciter 102 in a specific direction, and identifies and screens the dielectric block 20 by the screening component 13 arranged on the spiral track 12. Specifically, it includes an identification unit 14, a controller, and a material return mechanism. The identification unit 14 identifies and determines the content of the conductive material on each surface of the dielectric block 20, and the controller determines whether the position of the dielectric block 20 is correctly placed, and transports the dielectric block 20 that is correctly placed to the debugging platform for debugging. The material return mechanism pushes the dielectric block 20 that is not placed correctly into the vibration disk 101, thereby realizing automatic screening and feeding of the filter, improving production efficiency, and meeting modern production needs.

[0046] In this embodiment, at least two identification units 14 are respectively disposed on the top and / or bottom and / or side of the spiral track 12, and at least one material return mechanism is disposed on the side of the spiral track 12. It can be seen that the dielectric block 20 typically has six sides. Two identification units 14 can each identify and judge one side of the dielectric block 20 and its adjacent sides to determine whether the dielectric block 20 is correctly positioned. Alternatively, three identification units 14 can each identify and judge any three sides of the dielectric block 20 to determine whether the dielectric block 20 is correctly positioned.

[0047] In this embodiment, a material ejection port 161 is provided on one side of the spiral track 12 facing the vibration disk 101 and corresponding to the position of the ejection mechanism. The ejection mechanism pushes the dielectric block 20 through the ejection port 161 and drops it into the vibration disk 101.

[0048] In this embodiment, the material ejection mechanism further includes a through hole 162 , which is formed on the side of the spiral track 12 and corresponds to the position of the ejection port 161 . The output end of the material ejection mechanism pushes the dielectric block 20 out through the through hole 162 .

[0049] In this embodiment, an air blowing device is connected to the through hole 162. When the identification unit 14 identifies that the material content parameters of the dielectric block 20 surface are different from the parameters preset in the controller, the controller outputs the air blowing device, which blows the dielectric block 20 through the through hole 162 and drops it into the vibrating plate 101 for further screening.

[0050] In some embodiments, the driving member is a cylinder or a solenoid valve, and the output end of the cylinder or the solenoid valve passes through the through hole 162. The controller controls the output end of the cylinder or the solenoid valve to push the medium block 20 into the vibration plate 101.

[0051] In this embodiment, identification unit 14 is a detection fiber 141 and also includes a detection port 142. Specifically, the conductive material content varies on each surface of dielectric block 20, resulting in a different ratio of dielectric material to conductive material on each surface of dielectric block 20. This results in different wave reflection characteristics for the detection signal from detection fiber 141. The controller compares the reflection signal parameters received by detection fiber 141 with preset parameters within the controller to determine whether the dielectric block 20 is correctly positioned. This embodiment utilizes detection fiber 141 to detect and identify filters based on their physical characteristics, eliminating the need for an additional detection and identification module. This provides strong adaptability and high detection precision, thereby improving identification accuracy and reliability.

[0052] Example 2

[0053] Figure 5 It is a schematic diagram of the top view of the vibration plate of the utility model.

[0054] Figure 6 It is a structural schematic diagram of the torsion and direction-changing section of the utility model.

[0055] like Figures 5 and 6 As shown, the spiral track 12 also includes a twisting section 122 for laterally flipping the dielectric block 20. Specifically, any section of the U-shaped track 121 is linearly rotated 90 degrees clockwise or counterclockwise around the longitudinal axis of the U-shaped track 121, forming a twisting section 122. When the dielectric block 20 passes through the twisting section 122, it flips 90 degrees laterally, changing its placement.

[0056] In this embodiment, a plurality of identification units 14 and a material return mechanism are respectively disposed on both sides of the twisting and redirecting section 122. Specifically, the plurality of identification units 14 are respectively disposed above the spiral track 12. The identification units 14 disposed on one side of the twisting and redirecting section 122 identify and judge the dielectric block 20, and if the dielectric block 20 is not positioned correctly, the dielectric block 20 is ejected via the material return mechanism. When a dielectric block 20 that is positioned correctly passes through the twisting and redirecting section 122, the identification units 14 disposed on the other side of the twisting and redirecting section 122 identify and judge the adjacent side of the dielectric block 20 that has been flipped sideways, and if the dielectric block 20 is not positioned correctly, the dielectric block 20 is ejected via the material return mechanism.

[0057] In some embodiments, a linear conveyor rail 18 is further included, connected to the exit end of the spiral track 12, to convey the dielectric block 20 to the commissioning platform. In this embodiment, the linear conveyor rail 18 is preferably a linear vibrating rail. Compared to traditional conveyor rails, the linear vibrating rail enables high-precision positioning and motion control, ensuring the accuracy and stability of the dielectric block 20 during operation. Furthermore, the linear vibrating rail's motion reduces mechanical friction, minimizing the impact on the surface material of the dielectric block 20 during transportation.

[0058] In this embodiment, a torsion-reversing section 122 is provided on the spiral track 12 to adjust the posture of the dielectric block 20, so that the identification unit 14 is only provided above the spiral track 12, thereby meeting the double-sided and multi-sided detection requirements of the dielectric block 20. There is no need to drill additional holes in the spiral track 12 body to install the identification unit 14, which has a higher degree of functional modularity and is convenient for maintenance and replacement.

[0059] 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.
