Description

Technical Field

[0001] The present invention belongs to the technical field of long-pin ceramic electrical connectors, and in particular relates to a processing device and method for long-pin ceramic electrical connectors. Background Art

[0002] Long-pin ceramic electrical connectors are core components of ignition / detonation systems. Therefore, they are subject to extremely stringent performance requirements in all aspects. Dimensional accuracy is the most critical parameter, playing a key role in product reliability. Long-pin ceramic electrical connectors consist of two parts: a ceramic connector end and a long pin. Due to the small size of the ceramic connector end, with an outer diameter of only φ5mm, φ8mm, φ10mm, or φ30mm, and the long pins being long, typically 110mm to 300mm, long-pin ceramic connectors, consisting of a small connector and long pins, can experience tilted or loose bonding during processing. In severe cases, the long pins can even fall off, rendering the product unusable. Currently, existing literature and patents related to bonding mainly focus on general bonding methods, such as resin bonding, rosin bonding, adhesives, mechanical connection, etc. These bonding methods are extremely simple, but the bonding process may cause skewed bonding. This skewed bonding can cause the long-pin ceramic electrical connector to be polished skewed during the subsequent polishing process, resulting in substandard product quality. Summary of the Invention

[0003] The main purpose of the present invention is to provide a processing device and method for long-pin ceramic electrical connectors. The technical problem to be solved is how to provide a processing device and method for long-pin ceramic electrical connectors, which can ensure that the long-pin ceramic electrical connectors are firmly bonded and prevent the long-pin ceramic electrical connectors from being skewed during the processing and polishing process, thereby improving the product qualification rate.

[0004] The purpose of the present invention and the technical problem solved are achieved by adopting the following technical solutions. According to the present invention, a processing device for a long-pin ceramic electrical connector is provided, which comprises:

[0005] A panel is arranged horizontally; a plurality of grooves opening downward are arranged on the bottom surface of the panel;

[0006] a support member, the support member supporting the panel;

[0007] A positioning hole is provided on the panel through the vertical direction;

[0008] a plurality of heating rods, wherein the heating rods are arranged in the groove;

[0009] and a plurality of bottom plates, each of the bottom plates corresponds to the heating rods one by one and is used for fixing the heating rods.

[0010] The purpose of the present invention and the solution to its technical problems can be further achieved by adopting the following technical measures.

[0011] Preferably, in the aforementioned processing device, there are multiple positioning holes; and the positioning holes are evenly distributed on the panel.

[0012] Preferably, in the aforementioned processing device, the positioning hole is formed by connecting two cylinders with different inner diameters; the upper cylinder is embedded in the panel; and the lower cylinder is embedded in the bottom surface.

[0013] Preferably, in the aforementioned processing device, the inner diameter of the upper cylinder is smaller than the inner diameter of the lower cylinder; and the longitudinal sections of the upper cylinder and the lower cylinder form a convex shape.

[0014] Preferably, in the aforementioned processing device, the inner diameter of the upper cylinder is 1 to 2 mm larger than the outer diameter of the tube pin.

[0015] Preferably, in the aforementioned processing device, the roughness of the panel is Ra ≥ 0.8 μm, and the flatness is ≤ 0.02 mm.

[0016] Preferably, in the aforementioned processing device, the support members are symmetrically arranged around the center of the panel.

[0017] Preferably, the aforementioned processing device further includes a heating controller and a temperature sensor; the heating controller is connected to the temperature sensor and the heating rod respectively; and the temperature sensor is connected to the bottom plate.

[0018] The purpose of the present invention and the solution to its technical problems are also achieved by adopting the following technical solutions. According to the present invention, a method for processing a long-pin ceramic electrical connector includes the following steps:

[0019] 1) Apply adhesive on the positioning hole and heat the adhesive at a temperature of 60-200°C;

[0020] 2) After the adhesive is melted, insert the long pins of the long-pin ceramic electrical connector into the positioning holes and press downward until the ceramic electrical connector is completely attached to the panel;

[0021] 3) Stop heating; press the ceramic electrical connector downward in a vertical direction until the panel temperature drops to 23-25° C. After the ceramic electrical connector is bonded to the panel surface, polish the ceramic electrical connector of the long-pin ceramic electrical connector;

[0022] 4) Finally, remove the polished long-pin ceramic electrical connector from the positioning hole.

[0023] Preferably, in the aforementioned processing method, in step 4): before removing the long-pin ceramic electrical connector from the positioning hole, the adhesive on the panel is first melted, and then the long-pin ceramic electrical connector is removed upwards.

[0024] By means of the above technical solution, the present invention provides a device and method for processing a long-pin ceramic electrical connector, which has at least the following advantages:

[0025] Before processing, there is some solder accumulation and protrusion of the pins on the ceramic end face of the long-pin ceramic electrical connector. In order to ensure the use needs of the product, the ceramic end face needs to be polished to grind off the accumulated solder and the protruding parts of the pins. When using conventional bonding devices, the ceramic end face of the long-pin ceramic electrical connector will be skewed when bonded to the platform. Since the bonding is already skewed, the ceramic end face will become skewed after polishing, which will eventually lead to unqualified product quality and unusable. The present invention provides positioning holes on the panel. When in use, it is only necessary to apply a certain amount of adhesive to the positioning holes, heat the adhesive, and after the adhesive melts, vertically insert the long-pin ceramic electrical connector into the positioning holes until the ceramic electrical connector of the long-pin ceramic electrical connector is tightly fitted with the panel. Bonding is achieved under the action of the melted adhesive, which can prevent the long-pin ceramic electrical connector and the panel from being deviated or skewed during bonding. It can also prevent the long-pin ceramic electrical connector from being skewed or falling off during the grinding process, thereby improving the product qualification rate.

[0026] The positioning hole provided in the device of the present invention is composed of two cylinders with different inner diameters, and the inner diameter of the upper cylinder is smaller than the inner diameter of the lower cylinder. This arrangement can fix the long pin of the long-pin ceramic electrical connector in the positioning hole, preventing the long-pin ceramic electrical connector from shaking when polishing the ceramic end face, resulting in skew polishing, which affects the product qualification rate.

[0027] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the following is a detailed description of the preferred embodiments of the present invention with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Figure 2 It is a longitudinal cross-sectional schematic diagram of the positioning hole of the present invention. DETAILED DESCRIPTION

[0030] To further illustrate the technical means and effectiveness of the present invention in achieving its intended objectives, the following, in conjunction with the accompanying drawings and preferred embodiments, provides a detailed description of the specific implementation, structure, features, and effectiveness of a grinding method and apparatus according to the present invention. In the following description, different references to "one embodiment" or "embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics of one or more embodiments may be combined in any suitable manner.

[0031] One embodiment of the present invention provides a processing device for a long-pin ceramic electrical connector, as shown in the attached Figures 1-2 As shown, it includes:

[0032] The panel 21 is arranged horizontally; a plurality of grooves opening downward are provided on the bottom surface of the panel 21;

[0033] a support member 23 , wherein the support member 23 supports the panel 21 ;

[0034] A positioning hole 31 is provided on the panel 21 in a vertical direction;

[0035] a plurality of heating rods 11, wherein the heating rods 11 are arranged in the groove;

[0036] and a plurality of bottom plates 22 , each of the bottom plates 22 corresponding to the heating rods 11 and used for fixing the heating rods 11 .

[0037] In the device provided by the present invention, the main function of the panel is to provide a processing platform for the grinding of long-pin ceramic electrical connectors. The ceramic end of the long-pin ceramic electrical connector needs to be placed on the panel, and then a grinding device is used to grind off the solder accumulated on the ceramic end and the protruding part of the pin. Therefore, if the long-pin ceramic electrical connector is placed crookedly, it will cause the grinding to be crooked, so it is extremely important to ensure that the long-pin ceramic electrical connector is placed horizontally.

[0038] The function of the support is to provide support for the panel.

[0039] Since the long-pin ceramic electrical connector is composed of long pins and ceramic electrical connectors, and the long pins are long and will affect the efficiency of polishing, the setting of the positioning holes can avoid the influence of the long pins on the polishing process.

[0040] The purpose of the present invention and the solution to its technical problems can be further achieved by adopting the following technical measures.

[0041] Preferably, in the aforementioned processing device, there are multiple positioning holes 31 ; the positioning holes 31 are evenly distributed on the panel 21 .

[0042] During use, the device of the present invention applies adhesive above the positioning holes. Therefore, when melting the adhesive, it is important to ensure that the adhesive is heated evenly to avoid uneven heating that could reduce the bonding effect. By evenly distributing the positioning holes on the panel, the present invention ensures that the adhesive applied to each positioning hole is heated evenly, preventing incomplete melting and enhancing the bonding strength between the long-pin ceramic electrical connector and the panel.

[0043] Preferably, in the aforementioned processing device, the positioning hole 31 is formed by connecting two cylinders with different inner diameters; the upper cylinder 32 is embedded in the panel; and the lower cylinder 33 is embedded in the bottom surface.

[0044] The positioning hole is composed of two cylinders with different inner diameters. During use, the long pin of the long-pin ceramic electrical connector will pass through the lower cylinder and the upper cylinder at one time through the panel until the ceramic electrical connector contacts the panel. Under the action of the melted adhesive, the bonding is completed to achieve the fixation of the long-pin ceramic electrical connector.

[0045] Preferably, in the aforementioned processing device, the inner diameter of the upper cylinder 32 is smaller than the inner diameter of the lower cylinder 33; and the longitudinal sections of the upper cylinder 32 and the lower cylinder 33 form a convex shape.

[0046] The present invention forms a convex shape by setting the inner diameter of the upper cylinder to be smaller than the inner diameter of the lower cylinder. Figure 2 As shown, because the long tube pin needs to be inserted into the positioning hole, there will be some gaps. If the inner diameter of the lower cylinder is smaller than the inner diameter of the upper cylinder, the long tube pin will shake in the positioning hole and will not be firmly fixed. Secondly, if the inner diameter of the lower cylinder is smaller than the inner diameter of the upper cylinder, the melted adhesive on the panel will accumulate in the lower cylinder, and the adhesive will block the lower cylinder, resulting in the long tube pin being unable to pass through the panel and the device being unusable. The present invention designs the positioning hole into a convex shape to avoid these situations.

[0047] Preferably, in the aforementioned processing device, the inner diameter of the inner ring of the upper cylinder 32 is 1 to 2 mm larger than the outer diameter of the tube pin.

[0048] The inner diameter of the upper cylinder of the present invention is 1 to 2 mm larger than the outer diameter of the long pin. If the inner diameter of the upper cylinder is too narrow, the long pin cannot be inserted. If the inner diameter of the upper cylinder is too wide, the positioning performance of the positioning hole will be reduced. The inner diameter of the upper cylinder of the present invention is 1 to 2 mm larger than the inner diameter of the long pin, which can enable the long pin to be smoothly and accurately inserted into the ceramic electrical connector, and can enable the long-pin ceramic electrical connector to be stably fixed on the panel, avoiding polishing failure due to loose fixation during the polishing process, and can increase the product qualification rate by 50%.

[0049] Preferably, in the aforementioned processing device, the roughness of the panel is Ra ≥ 0.8 μm, and the flatness is ≤ 0.02 mm.

[0050] The panel of the present invention has a roughness of Ra ≥ 0.8 μm and a flatness of ≤ 0.02 mm. By controlling the roughness and flatness of the panel, the ceramic electrical connector can be placed horizontally on the panel. If the panel's roughness and flatness are too large, the long-pin ceramic electrical connector will be skewed and unstable when bonded, and the polished surface of the product after polishing will also be skewed. The present invention, however, uses a panel with a roughness of Ra ≥ 0.8 μm and a flatness better than 0.02 mm, which avoids these problems. It allows the ceramic end of the long-pin ceramic electrical connector to be placed horizontally, preventing skewed bonding that could lead to skewed polished surfaces, thereby improving the product's pass rate.

[0051] Preferably, in the aforementioned processing device, the support member 23 is symmetrically arranged with respect to the center of the panel 21 .

[0052] The long-pin ceramic electrical connector consists of a long pin and a ceramic electrical connector. If the long pin is too long, it will interfere with the polishing process. On the one hand, the support member provided in the present invention can provide support for the panel. The panel can be set parallel to the center symmetrically of the panel, which can ensure that the long-pin ceramic electrical connector is placed in parallel to prevent polishing deviation. On the other hand, the setting of the support member can provide a certain space, so that the long pin can be placed vertically.

[0053] Preferably, the aforementioned processing device further includes a heating controller 13 and a temperature sensor 12 ; the heating controller 13 is connected to the temperature sensor 12 and the heating rod 11 , respectively; and the temperature sensor 12 is connected to the bottom plate 22 .

[0054] The purpose of the present invention and the solution to its technical problems are also achieved by adopting the following technical solutions. According to the present invention, a method for processing a long-pin ceramic electrical connector includes the following steps:

[0055] 1) Apply adhesive on the positioning hole and heat the adhesive at a temperature of 60-200°C;

[0056] 2) After the adhesive is melted, insert the long pins of the long-pin ceramic electrical connector into the positioning holes and press downward until the ceramic electrical connector is completely attached to the panel;

[0057] 3) Stop heating; press the ceramic electrical connector downward in a vertical direction until the panel temperature drops to 23-25° C. After the ceramic electrical connector is bonded to the panel surface, polish the ceramic electrical connector of the long-pin ceramic electrical connector;

[0058] 4) Finally, remove the polished long-pin ceramic electrical connector from the positioning hole.

[0059] The device of the present invention is simple to use. When in use, a certain amount of adhesive is applied to the positioning hole, and then the panel is heated to melt the adhesive. After the adhesive melts, the long pin is inserted into the positioning hole and pressed vertically downward until the ceramic electrical connector contacts the panel. Then the heating is stopped. After the panel cools down, the fixing operation of the long-pin ceramic electrical connector is completed. At this time, polishing can be performed. After the polishing is completed, the polished long-pin ceramic electrical connector is taken out.

[0060] The heating temperature depends on the type of adhesive. Generally, the adhesive selected is rosin, paraffin or a mixture of the two, and the heating temperature is 80℃~150℃.

[0061] Preferably, in the aforementioned processing method, in step 4): before removing the long-pin ceramic electrical connector from the positioning hole, the adhesive on the panel is first melted, and then the long-pin ceramic electrical connector is removed upwards.

[0062] Before removal, the long-pin ceramic connector is bonded to the panel, and the long pins are bonded to the sidewalls of the positioning holes. Therefore, physically pulling the connector upwards is difficult to remove. Furthermore, if the upward pulling direction is off, the long pins may break. The present invention, however, first heats the panel to partially melt the adhesive, and then immediately removes the connector. This simplifies the process and significantly improves work efficiency.
