Description

Technical Field

[0001] The invention belongs to the technical field of loading tooling, and in particular relates to a connector loading tooling and method. Background Art

[0002] With the development of lightweight and miniaturized high-frequency electronic equipment, SMP-KK connectors are increasingly used in the fields of communications and radars due to their good microwave performance and vertical interconnection structure advantages. SMP-KK is an ultra-small push-in connector that adopts a blind-plug-in installation method. It is currently mainly assembled manually, and the number of installations is large. The traditional installation method is to manually take the connectors out of the packaging box one by one, and then put them into the SMP-KK connector installation tool one by one for installation. This manual picking method is inefficient and not conducive to production. The current existing automatic assembly method uses a vibrating disk-type loading device, which can only load one SMP-KK connector at a time and is relatively expensive.

[0003] SMP-KK connectors are small in size and are used in large quantities. The traditional manual feeding method requires repetitive actions, which is labor-intensive and inefficient. The manual or existing vibration plate feeding method can only complete the feeding of one SMP-KK connector at a time, which is not suitable for the feeding of SMP-KK connectors of multiple varieties and small batches. The feeding efficiency does not meet the use requirements and the cost is high.

[0004] According to the characteristics of SMP-KK connectors and the demand for small-batch production of multiple varieties, a low-cost SMP-KK connector loading tooling suitable for both automatic and manual installation methods is needed to solve the problems of low efficiency and repetitive labor in manual loading. It has the advantages of a large number of one-time loading and easy operation; at the same time, it can meet the automatic assembly needs of SMP-KK connectors.

[0005] The patent document with announcement number CN221700434U discloses a SMP-KK connector quick loading device, including a vibrating machine with a vibrating table at the upper end, a material tray is provided on the upper surface of the vibrating table, and the upper surface of the material tray is provided with material holes arranged in an array, a screening net is provided above the material tray, and the screening net has screening holes corresponding to the material holes one by one; the device is based on the hourglass principle, and uses a vibrating machine to allow the material above the screening net to pass through the screening holes into the material holes of the material tray, thereby realizing the function of automatic loading, but the screening holes of the device are vertically arranged circular holes, and there is no corresponding structure to release the sliding stress of the connector, and it cannot completely solve the technical problem that the connector slides vertically into the hole without popping out, and at the same time, the material tray has no partition structure, and connectors of different specifications cannot be loaded at the same time. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a connector feeding tool and method.

[0007] The present invention is achieved through the following technical solutions.

[0008] The present invention provides a connector loading tool, comprising an upper die and a lower die, wherein the upper die is connected to the lower die, a guide structure is arranged on the upper die, and a position groove is arranged on the lower die.

The groove, slide groove A and slide groove B are arranged from top to bottom on the upper mold at one time, the top of the slide groove A is connected to the groove, and the bottom of the slide groove A is connected to the slide groove B.

[0010] Preferably, a plurality of slide grooves A are linearly distributed at the bottom of the groove, the cross section of the slide groove A is trapezoidal, and the top of the slide groove B is connected to the lowest end of the inclined surface of the slide groove A.

[0012] Preferably, a hole A is diagonally arranged on the upper die, and handles are symmetrically arranged on both sides of the upper die and the lower die, and the handles are made of aluminum alloy.

[0013] Preferably, the lower mold is made of aluminum alloy, and a fixing piece is diagonally arranged on the surface of the lower mold on the side close to the upper mold. The diameter of the position groove is larger than the diameter of the connector, and the depth of the position groove is 1 / 3-4 / 5 of the length of the connector.

[0014] A method for processing a connector feeding tool comprises the following steps:

[0015] The processing steps of the upper mold include:

[0016] S1: After the upper die blank is processed into a hexagonal shape, a pressing plate is used to press the blank onto the workbench of the machining center. The milling cutter is used to process the groove and the slide A in sequence. Then the drill A is used to process the slide B and the hole A is opened. Finally, the handle is installed.

[0017] The processing steps of the lower die include:

[0018] S1: After processing the blank of the lower die into a hexagonal shape, process the fixing parts, clamp the blank body, use drill bit B to drill the bottom hole, then obtain the position groove through milling, and finally install the handle.

[0019] In the processing step of the upper die, after the blank is processed into a hexagon, the verticality of each surface of the blank is controlled within 0.05 mm, the flatness of the bottom surface of the blank is controlled within 0.02 mm, the inclined surface is processed by a milling cutter using a profile streamline milling method, the chamfering of the mouth of the chute B is processed by a chamfering cutter, and the trumpet-shaped chute B is processed and formed in one step using a drill A,

[0020] The drill bit A includes a main body, a processing part A and a processing part B. A thread groove is arranged on the drill bit A. The main body is connected through the processing part A and the processing part B. The processing part A is in a truncated cone shape. The large end of the processing part A is connected to the main body. The end of the processing part B away from the processing part A is conical.

[0021] In the processing steps of the lower die, after the blank is processed into a hexagon, the verticality of each surface of the blank is controlled within 0.05mm, and the bottom surface of the blank is controlled within 0.02mm. After processing the fixing parts, the blank body is positioned and clamped by means of two pins on one side, the bottom hole is drilled using drill bit B, and then the position groove is processed by insert milling using an end mill.

[0022] A method for using a connector feeding tool comprises the following steps:

[0023] S1: Fix the upper die to the lower die through the fixing parts to ensure that the upper die and the lower die are in accurate positions and do not move relative to each other;

[0024] S2: Place the connector at any position on the upper die, hold the handles on both sides of the upper die or lower die with both hands, and gently shake the tooling horizontally. The connector is subjected to the horizontal force, slides into the groove, enters the slide A, and then into the slide B, and then slides into the position groove of the lower die. The tooling can also be placed on a vibration device, and the connector can be slid into the position groove by relying on the vibration frequency;

[0025] S3: Visually check that all connectors are located in the position grooves, and remove the upper mold to complete the loading.

[0026] The beneficial effects of the present invention are:

[0027] 1. The tooling of the present invention adopts organic glass material, and the non-metallic design can well protect the outer surface of the connector from being scratched, thereby ensuring the appearance quality of the connector; the upper die of the tooling is provided with a guide slide groove A and a bell-mouth slide groove B, and adopts a 30° inclined surface and a chamfered design at the connection between the slide groove A and the slide groove B. When the connector slides into the lower die position groove, the two-stage structure design composed of the slide groove A and the slide groove B can gradually reduce the force in the one direction of the connector during the sliding process, and can well limit the connector from being easily ejected during the sliding process, thereby ensuring that the connector can easily slide into the lower die position groove; the upper die and the lower die of the tooling are positioned and fixed with stainless steel pins with a diameter of 3 to 4 mm, and the diagonal layout design is used to ensure the hole alignment accuracy between the upper die and the lower die.

[0028] 2. The tooling of the present invention can be shaken manually or by a vibration device to make multiple connectors of various specifications automatically slide into the slide slot and enter the position slot at the same time. It does not need to use other classification setting equipment, nor does it need to be manually placed one by one. It can easily realize the automatic loading of multiple connectors, reduce the loading time during automatic assembly, and reduce the labor intensity of operators. This tooling can be promoted and applied to the loading of multiple miniaturized connectors with the same structure at both ends, and has a good application prospect.

[0035] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0036] Example:

[0037] like Figures 1 to 5 As shown, a connector loading tool comprises an upper die 1 and a lower die 2, wherein the upper die 1 and the lower die 2 are connected, a guide structure is arranged on the upper die 1, and a position groove 21 is arranged on the lower die 2.

[0038] The upper mold 1 is made of organic glass, and the outer surface of the SMP-KK connector is a gold-plated layer. The organic glass material can effectively protect the gold-plated layer from damage. The guide structure includes a groove 11, a slide groove A12 and a slide groove B13. The groove 11, the slide groove A12 and the slide groove B13 are arranged from top to bottom on the upper mold 1 at one time. The top of the slide groove A12 is connected to the groove 11, and the bottom of the slide groove A12 is connected to the slide groove B13. The upper mold 1 can be designed in different areas, and a group of grooves 11, slide grooves A12 and slide grooves B13 of different specifications are set for SMP-KK connectors of different models and specifications, so that SMP-KK connectors of different models and specifications can be loaded at the same time.

[0039] A plurality of slide grooves A12 are linearly distributed at the bottom of the groove 11 , and the cross section of the slide groove A12 is trapezoidal. The top of the slide groove B13 is connected to the lowest end of the inclined surface 121 of the slide groove A12 .

[0040] The angle of the inclined surface 121 is 20-40°, preferably 30°, which can better ensure that the SMP-KK connector can slide into the slide groove B13. The slide groove B13 is arranged in a trumpet shape. The trumpet shape can release the sliding stress of the SMP-KK connector in a limited manner, ensuring that the SMP-KK connector slides vertically into the position groove 21 of the lower mold 2 without popping out. The end of the slide groove B13 close to the slide groove A12 is the large end, and the diameter of the small end of the slide groove B13 is larger than the diameter of the SMP-KK connector by 1mm. The connection between the slide groove B13 and the slide groove A12 is chamfered.

[0041] The upper mold 1 is diagonally provided with a hole A14, and handles 3 are symmetrically provided on both sides of the upper mold 1 and the lower mold 2. The handle 3 is made of aluminum alloy, has a U-columnar design, and has a sandblasted outer surface to prevent the handle from slipping. The handle is threadedly connected to the upper mold 1 and the lower mold 2 for easy disassembly.

[0042] The lower mold 2 is made of aluminum alloy and has a sandblasted outer surface. A fixing part 22 is arranged diagonally on the surface of the lower mold 2 on the side close to the upper mold 1. The fixing part 22 is a pin. The fixing part 22 passes through the hole A14 to realize the alignment and fixation of the upper mold 1 and the lower mold 2, thereby ensuring the precise alignment of the slide groove B13 and the position groove 21 in the upper mold 1 and the lower mold 2. According to the different specifications of SMP-KK connectors, the diameter of the position groove 21 is 0.3-0.5mm larger than the diameter of the SMP-KK connector, and the depth of the position groove 21 is 1 / 3-4 / 5 of the length of the SMP-KK connector, preferably 2 / 3, to ensure that the SMP-KK connector is not skewed when vertically located in the position groove 21, thereby facilitating accurate picking.

[0043] A method for processing a connector feeding tool comprises the following steps:

[0044] The processing steps of the upper mold 1 include:

[0045] S1: After the blank of the upper die 1 is processed into a hexagonal shape, a pressing plate is used to press the blank onto the workbench of the machining center. The groove 11 and the slide groove A12 are processed in sequence using a milling cutter. Then, the slide groove B13 is processed using a drill A, and a hole A14 is opened. Finally, the handle 3 is installed.

[0046] The processing steps of the lower mold 2 include:

[0047] S1: After the blank of the lower die 2 is processed into a hexagonal shape, the fixing part 22 is processed, and after the blank body is clamped, a bottom hole is drilled using a drill bit B, and then a position groove 21 is obtained by milling, and finally the handle 3 is installed.

[0048] In the processing step of the upper die 1, after the blank is processed into a hexagon, the verticality of each surface of the blank is controlled within 0.05 mm, the flatness of the bottom surface of the blank is controlled within 0.02 mm, the inclined surface 121 is processed by a milling cutter using a profile streamline milling method, the chamfering of the mouth of the chute B13 is processed by a chamfering cutter, and the trumpet-shaped chute B13 is processed and formed in one step using a drill A,

[0049] The drill bit A includes a main body 4, a processing part A41 and a processing part B42. A threaded groove 43 is arranged on the drill bit A for forming the slide groove B13. The main body 4 is connected through the processing part A41 and the processing part B42. The processing part A41 is in a truncated cone shape. The inclination angle of the side of the processing part A41 determines the size of the bell-shaped part of the groove B13. The large end of the processing part A41 is connected to the main body 4. The end of the processing part B42 away from the processing part A41 is conical. When in use, the bell-shaped part of the slide groove B13 is processed by the processing part A41, and the slide groove B13 is drilled through by the processing part B42.

[0050] In the processing steps of the lower mold 2, after the blank is processed into a hexagon, the verticality of each surface of the blank is controlled within 0.05mm, and the bottom surface of the blank is controlled within 0.02mm. After processing the fixing part 22, the blank body is positioned and clamped by means of two pins on one side, and the bottom hole is drilled with a drill bit B. Then, the position groove 21 is processed by a milling method using an end mill. This method can effectively ensure that the diameter accuracy of the connector mounting hole is 0.02mm, and the verticality of the axis of the position groove 21 and the surface plane is 0.01mm.

[0051] A method for using a connector feeding tool comprises the following steps:

[0052] S1: Fix the upper die 1 on the lower die 2 through the fixing member 22 to ensure that the upper die 1 and the lower die 2 are positioned accurately, each bottom of the slide groove B13 corresponds to a position groove 21, and the upper die 1 and the lower die 2 do not move relative to each other;

[0053] S2: Place a certain number of SMP-KK connectors at any position on the upper mold 1 at the same time, hold the handles 3 on both sides of the upper mold 1 or the lower mold 2 with both hands, and shake the tooling horizontally. The SMP-KK connectors are subjected to the horizontal force and slide into the groove 11 along the direction of the force, then into the slide groove A12, and then into the slide groove B13. Under the action of their own gravity, they slide into the position groove 21 of the lower mold 2. The tooling can also be placed on a vibration device to slide the SMP-KK connector into the position groove 21 by relying on the vibration frequency;

[0054] S3: Visually check that all SMP-KK connectors are located in the position slot 21, and remove the upper mold 1 to complete the loading.
