Description

Technical Field

[0001] The present invention relates to the technical field of connector assembly, and in particular to an assembly and positioning mechanism and method for a thin-sheet terminal shielding sheet. Background Art

[0002] A connector, also known as a connector, plug, or socket in China, generally refers to an electrical connector. It's a device that connects two active components, transmitting current or signals. Connectors are a component that electronic engineers often come into contact with.

[0003] The PSAS5.0 series of high-speed female connectors, due to structural limitations, has a large number of wafers and is therefore long. The connector features a variety of terminal types, including BL, 7-pin wafer, SAS6-pin, SATA15-pin, and 40-pin wafer. The assembly of these wafer terminals is not yet automated, requiring a step-by-step process. Existing technology involves manually assembling the bent wafer terminals and inserting them into a plastic housing, a process that is extremely inefficient and labor-intensive. During assembly, a shielding sheet must be added to the wafer terminals before the terminals are inserted into the connector's plastic housing.

[0004] Since the wafer terminal and the shielding sheet are relatively small in size, it is difficult to position the shielding sheet when installing it on the wafer terminal, resulting in unstable installation of the shielding sheet. Summary of the Invention

[0005] The purpose of the present invention is to provide a thin-sheet terminal shielding sheet assembly positioning mechanism and method, which can achieve precise positioning of the wafer terminal body in actual use, so as to stably install the shielding sheet on the wafer terminal body and improve installation accuracy.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A wafer terminal shielding sheet assembly positioning mechanism includes a first positioning mechanism and a second positioning mechanism for being installed on both sides of a wafer terminal body driving mechanism.

[0008] Its characteristics are:

[0009] The first positioning mechanism includes a mounting base for mounting on a frame of the wafer terminal body driving mechanism, a first telescopic rod fixedly mounted on the mounting base, a push block slidably mounted on the mounting base and connected to the first telescopic rod, and a positioning unit slidably mounted on the mounting base;

[0010] The positioning unit includes a positioning block, a slide and a roller. A limiting portion is provided on both sides of the positioning block, and a U-shaped limiting area is formed between the limiting portion and the positioning block. The positioning block is connected to a slide that is slidably arranged above the mounting seat. A clearance groove is provided on the slide, and the roller is rotatably installed in the clearance groove.

[0011] An inclined surface is provided on the push block, and a tension spring is provided between the mounting seat and the slide. Under the action of the tension spring, the roller and the inclined surface contact each other; the second positioning mechanism is located on the other side of the frame of the wafer terminal body driving mechanism, and the second positioning mechanism is used to push the wafer terminal body into the U-shaped limiting area to achieve limiting and fixing of the wafer terminal body.

[0012] Furthermore, the wafer terminal body driving mechanism includes a frame, a feeding track and a driving unit arranged on the frame, a wafer terminal body flow channel is arranged on the feeding track, and the driving unit is used to drive the wafer terminal body to move intermittently in the wafer terminal body flow channel, and a first guide groove and a second guide groove are arranged on the feeding track. The first guide groove and the second guide groove are connected to the wafer terminal body flow channel, and the limiting part on the positioning block is slidably arranged in the first guide groove and the second guide groove respectively. After the limiting part extends out of the first guide groove and the second guide groove, it is used to limit the wafer terminal body.

[0013] Wherein, both the mounting seat and the slide plate are provided with mounting holes, and the tension spring is fixedly arranged in the mounting hole.

[0014] Furthermore, a guiding inclined surface for guiding the wafer terminal body is provided on a side of the limiting portion close to the wafer terminal body.

[0015] Further optimization is achieved by sliding connection between the mounting seat and the slide plate through a slide groove and a slide rail.

[0016] It is further defined that the slide groove is a dovetail groove or a T-slot, and the shape of the slide rail matches the shape of the slide groove.

[0017] Furthermore, the roller is rotatably installed in the clearance groove through a pin shaft.

[0018] Preferably, a clearance notch is provided on the limiting portion near the upper side of the wafer terminal body.

[0019] Furthermore, the second positioning mechanism includes a second telescopic rod, a support frame, a push frame and a lower pressure plate. The support frame is fixedly installed on the frame of the wafer terminal body feeding mechanism. The second telescopic rod is connected to the push frame after being installed on the support frame. The push frame is slidably installed on the support frame. The lower pressure plate is fixedly connected to the push frame. After the lower pressure plate moves, it is located above the wafer terminal body.

[0020] The present invention also discloses a wafer terminal shielding piece assembly and positioning method, which comprises using the wafer terminal shielding piece assembly and positioning mechanism to position the wafer terminal body.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present invention is mainly used for automatically installing a shielding sheet on a wafer terminal body to achieve positioning and fixing of the wafer terminal body, so as to achieve installation of the shielding sheet. During use, the wafer terminal body driving mechanism is used to achieve intermittent feeding of the wafer terminal body. When the wafer terminal body reaches a preset position, the push block is pushed under the action of the first telescopic rod. After the push block moves upward, the roller in contact with the upper inclined surface of the push block will drive the sliding movement. Under the action of the second positioning mechanism, the wafer terminal body enters the U-shaped limiting area to achieve limiting and fixing of the wafer terminal body. It can ensure that the wafer terminal body is located in the same position, and when the shielding sheet is installed on the wafer terminal body, the installation accuracy is higher.

[0037] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0038] See Figure 1-Figure 5 This embodiment discloses a thin-film terminal shielding sheet assembly positioning mechanism, including a first positioning mechanism 102 and a second positioning mechanism 103 for being installed on both sides of a wafer terminal body driving mechanism 101.

[0039] The first positioning mechanism 102 includes a mounting base 105 for mounting on a frame 104 of the wafer terminal body driving mechanism 101, a first telescopic rod 106 fixedly mounted on the mounting base 105, a push block 107 slidably mounted on the mounting base 105 and connected to the first telescopic rod 106, and a positioning unit slidably mounted on the mounting base 105;

[0040] The positioning unit includes a positioning block 108, a slide 109 and a roller 110. A limiting portion 111 is provided on both sides of the positioning block 108. A U-shaped limiting area is formed between the limiting portion 111 and the positioning block 108. The positioning block 108 is connected to the slide 109 slidably provided above the mounting seat 105. A clearance groove 112 is provided on the slide 109. The roller 110 is rotatably installed in the clearance groove 112.

[0041] A slope 113 is provided on the push block 107, and a tension spring is provided between the mounting seat 105 and the slide 109. Under the action of the tension spring, the roller 110 and the slope 113 contact each other; the second positioning mechanism 103 is located on the other side of the frame 104 of the wafer terminal body driving mechanism 101, and the second positioning mechanism 103 is used to push the wafer terminal body 115 into the U-shaped limiting area to achieve limiting and fixing of the wafer terminal body 115.

[0042] The present invention is mainly used to position and fix the wafer terminal body 115 when automatically installing the shielding sheet 114 on the wafer terminal body 115, so as to achieve the installation of the shielding sheet 114. When in use, the wafer terminal body driving mechanism 101 is used to achieve intermittent feeding of the wafer terminal body 115. When the wafer terminal body 115 reaches the preset position, the push block 107 is pushed under the action of the first telescopic rod 106. After the push block 107 moves upward, the roller 110 in contact with the inclined surface 113 on the push block 107 will drive the slide 109 to move. Under the action of the second positioning mechanism 103, the wafer terminal body 115 enters the U-shaped limiting area to achieve the limiting and fixing of the wafer terminal body 115. It can ensure that the wafer terminal body 115 is located in the same position, and when the shielding sheet 114 is installed on the wafer terminal body 115, the installation accuracy is higher.

[0043] Among them, the wafer terminal body driving mechanism 101 includes a frame 104, a feeding track 116 and a driving unit 117 arranged on the frame 104, a wafer terminal body flow channel 118 is arranged on the feeding track 116, and the driving unit 117 is used to drive the wafer terminal body 115 to move intermittently in the wafer terminal body flow channel 118, and a first guide groove 119 and a second guide groove 120 are arranged on the feeding track 116. The first guide groove 119 and the second guide groove 120 are connected to the wafer terminal body flow channel 118, and the limiting part 111 on the positioning block 108 is respectively slidably arranged in the first guide groove 119 and the second guide groove 120. After the limiting part 111 extends out of the first guide groove 119 and the second guide groove 120, it is used to limit the wafer terminal body 115.

[0044] It should be noted that, in this embodiment, the driving unit 117 is an intermittent toggle driving device, and its structure is not described in detail here.

[0045] In actual use, the driving unit 117 drives the wafer terminal body 115 to move intermittently in the wafer terminal body flow channel 118. At the same time, the limiting portion 111 extends out of the first guide groove 119 and the second guide groove 120 to limit the wafer terminal body 115.

[0046] Among them, both the mounting seat 105 and the slide plate 109 are provided with mounting holes, and the tension spring is fixedly arranged in the mounting hole, so that the slide plate 109 can achieve the purpose of automatic reset.

[0047] Furthermore, in actual use, a guiding inclined surface for guiding the wafer terminal body 115 is provided on the side of the limiting portion 111 close to the wafer terminal body 115 .

[0048] The provided guiding slope can serve the purpose of guiding, so that the wafer terminal body 115 can enter the U-shaped limiting area more smoothly, thereby ensuring that the wafer terminal body 115 can reach the preset position.

[0049] The mounting seat 105 and the slide plate 109 are slidably connected via a slide groove and a slide rail.

[0050] In actual use, the slide groove is a dovetail groove or a T-shaped groove, and the shape of the slide rail matches the shape of the slide groove, so that the mounting seat 105 and the slide plate 109 can slide stably.

[0051] The roller 110 is rotatably installed in the clearance groove 112 via a pin shaft.

[0052] Among them, the second positioning mechanism 103 includes a second telescopic rod 121, a support frame 122, a push frame 123 and a lower pressure plate 124. The support frame 122 is fixedly installed on the frame 104 of the wafer terminal body 115 feeding mechanism. After the second telescopic rod 121 is installed on the support frame 122, it is connected to the push frame 123. The push frame 123 is slidably installed on the support frame 122. The lower pressure plate 124 is fixedly connected to the push frame 123. After the lower pressure plate 124 moves, it is located above the wafer terminal body 115.

[0053] In actual use, a negative pressure adsorption device is used to adsorb the shielding sheet 114, and the shielding sheet 114 is installed on the wafer terminal body 115. The second telescopic rod 121 drives the push frame 123 to move, so that the lower pressure plate 124 moves toward the wafer terminal body 115 to above the shielding sheet 114 on the wafer terminal body 115. At this time, the lower pressure plate 124 will be located above the shielding sheet 114 to prevent the installed shielding sheet 114 from being taken away from the wafer terminal body 115 when the negative pressure adsorption device is reset. After the negative pressure suction head is reset, the lower pressure plate 124 is reset horizontally, and the wafer terminal body 115 with the shielding sheet 114 installed is moved to the next process.

[0054] Furthermore, a clearance notch is provided on the limiting portion 111 near the upper portion of the wafer terminal body 115 , and the clearance notch can serve the purpose of making way for the lower pressing plate 124 .

[0055] In actual use, the second positioning mechanism 103 also includes a fixing seat 125, a fixing block 126 and a spring. The fixing seat 125 is fixedly set on the push frame 123, and a slot connected to the wafer terminal body flow channel 118 is provided on the wafer terminal body flow channel 118. The fixing block 126 is slidably set in the slot, and the spring is provided between the fixing block 126 and the fixing seat 125; when in use, when the push frame 123 moves, it can drive the fixing seat 125 to move, so that the fixing block 126 passes through the slot and contacts the side of the wafer terminal body 115, thereby fixing the wafer terminal body 115 on the inner wall of the wafer terminal body flow channel 118, and at this time, the wafer terminal body 115 is fixed in all directions under the action of the pressure plate and the limiting part 111; when the fixing block 126 fixes the wafer terminal body 115 on the wafer terminal body flow channel 118 under the action of the spring, the push frame 123 still moves to ensure that the pressure plate is located above the wafer terminal body 115.

[0056] More importantly, after the shielding sheet 114 is installed, the push frame 123 is reset, and the pressure plate will leave the top of the wafer terminal body 115 from the side, while the fixing block 126 still fixes the wafer terminal body 115.

[0057] Furthermore, in actual use, a cover plate is provided on the wafer terminal body flow channel 118 for closing the wafer terminal body flow channel 118 .

[0058] In addition, this embodiment also discloses a method for assembling and positioning a thin-sheet terminal shielding sheet 114 , which includes using the above-mentioned assembly and positioning mechanism for the wafer terminal shielding sheet 114 to perform positioning.

[0059] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
