[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] like Figures 1-7 As shown, the specific embodiment adopts the following technical solution: it includes a fixing frame 1, a base plate 2 and a positioning rod 3. The base plate 2 is provided on the upper part of the fixing frame 1, and the positioning rod 3 is fixedly provided on both the left and right sides of the rear side wall of the base plate 2.

[0022] It also includes:

[0023] Mounting plate 4, there are two mounting plates 4, which are respectively fixedly installed on the left and right sides of the bottom of the base plate 2, and the mounting plates 4 are abutted in the two mounting holes opened on the fixing frame 1. Locking pressure plate 5 is abutted on the front side wall of the two mounting plates 4, and locking mechanism 13 connected to the mounting plate 4 is provided in the locking pressure plate 5.

[0024] Fixing block 6, there are several fixing blocks 6, all of which are fixedly installed on the rear side wall of the base plate 2. A pneumatic suction cup 7 is provided on the rear side of the fixing block 6, and a convenient disassembly and assembly mechanism 15 connected to the pneumatic suction cup 7 is provided inside the fixing block 6.

[0025] A rotating rod 8 is rotatably mounted in a groove on the front side wall of the fixed frame 1 via a bearing. A control plate 9 is fixedly mounted on the rotating rod 8. A torsion spring connected to the control plate 9 is fixedly mounted in the groove. A screw 10 is rotatably mounted in the fixed frame 1 via a bearing. The lower end of the screw 10 is connected to the rotating rod 8 via a bevel gear pair.

[0026] The limiting cylinder 11 is threadedly sleeved on the upper end of the screw 10. The limiting cylinder 11 is movably inserted into the polygonal groove opened on the upper part of the fixing frame 1. The upper end of the limiting cylinder 11 is movably inserted into the groove opened at the bottom of the locking plate 5. Two guide rods 12 are fixedly installed on the rear side wall of the locking plate 5, and the guide rods 12 are movably inserted into the slots opened on the fixing frame 1. The rear end of the guide rod 12 is fixedly provided with a limiting block 16. The limiting block 16 is movably abutting against the slot. The limiting block 16 can restrict the movement of the guide rod 12 in the slot and prevent the guide rod 12 from being pulled out directly from the slot.

[0027] The locking mechanism 13 includes:

[0028] Gear 13-1 is rotatably mounted in locking plate 5 via a rotating shaft. Several bolts 13-2 with rounded corners are rotatably mounted on the locking plate 5 at the outer position of gear 13-1 via bearings. Gear 13-3, which meshes with gear 13-1, is fixedly sleeved on bolts 13-2.

[0029] The fixing cylinder 13-4 consists of several cylinders, which are fixedly installed in two mounting ports. The fixing cylinder 13-4 is movably inserted into the through hole opened on the mounting plate 4. The rear end of the bolt 13-2 is inserted into the fixing cylinder 13-4 by thread rotation. The locking mechanism 13 can provide convenient limit for the mounting plate 4 in the mounting port, thereby realizing convenient loading and unloading of the substrate 2 on the fixing frame 1. A crossbar 14 is rotatably installed in the locking pressure plate 5 through the bearing. The two ends of the crossbar 14 are respectively connected to the rotating shafts on the two first gears 13-1 through the bevel gear pair. By utilizing the cooperation between the crossbar 14 and the bevel gear pair, the synchronous rotation of the first gears 13-1 on both sides can be realized, thereby further improving the convenience of loading and unloading the substrate 2.

[0030] The convenient disassembly and assembly mechanism 15 includes:

[0031] Polygonal block 15-1 is fixedly mounted on pneumatic suction cup 7 and movably inserted into fixed block 6. Pressing rods 15-2 are movably inserted on both the left and right sides of fixed block 6.

[0032] Two locking blocks 15-3 are movably disposed on the left and right sides inside the fixed block 6, respectively. Each locking block 15-3 is engaged in a slot opened on the polygonal block 15-1. One end of the pressing rod 15-2 is fixedly connected to the locking block 15-3. Springs 15-6 are connected to the upper and lower sides between the two locking blocks 15-3. The convenient disassembly and assembly mechanism 15 allows for convenient mounting and disassembly of the pneumatic suction cup 7 on the fixed block 6, facilitating the replacement of damaged pneumatic suction cup 7. A third gear 15-4 is rotatably mounted inside the fixed block 6 via a rotating shaft. Racks 15-5 mesh with both the upper and lower sides of the third gear 15-4. One end of the rack 15-5 is fixedly connected to the locking block 15-3. By utilizing the meshing of the rack 15-5 and the third gear 15-4, the pressing rods 15-2 on both sides of several fixed blocks 6 can move synchronously and in opposite directions. This avoids the locking blocks 15-3 from getting stuck when the two locking blocks 15-3 are not synchronized.

[0033] When using this utility model, the fixing frame 1 is connected to a moving mechanism such as a robotic arm or a movable slide. When it is necessary to unload the connector, the robotic arm or movable slide is used to move the unloading fixture closer to the connector, and the pneumatic suction cup 7 is used to adsorb and fix the processed connector. Then the connector is moved to the unloading position, and the pneumatic suction cup 7 releases the connector to realize the unloading of the connector.

[0034] When the pneumatic suction cup 7 is damaged and needs to be replaced, the pressing rods 15-2 on both sides of the fixing block 6 can be pressed simultaneously towards the fixing block 6. The pressing rods 15-2 drive the locking blocks 15-3 to move in the slots, and the spring 15-6 is compressed by the two locking blocks 15-3. At this time, the locking blocks 15-3 disengage from the slots. Then, the pneumatic suction cup 7 can be moved away from the fixing block 6, so that the polygonal block 15-1 disengages from the fixing block 6. At the same time, the locking blocks 15-3 completely disengage from the slots, completing the disassembly of the pneumatic suction cup 7. After that, the polygonal block 15-1 on the newly replaced pneumatic suction cup 7 is inserted into the fixing block 6, so that the locking blocks 15-3 are inserted into the slots on the polygonal block 15-1. Then, the pressing rods 15-2 are released. At this time, the spring 15-6 returns to its original position and extends, pushing the locking blocks 15-3 on both sides to move in opposite directions, so that the locking blocks 15-3 are locked in the slots, and the installation limit of the pneumatic suction cup 7 and the polygonal block 15-1 is achieved.

[0035] When it is necessary to replace the substrate 2 with a suitable one according to the connector specifications, the control plate 9 can be pressed towards the fixing frame 1, causing the control plate 9 to flip to a vertical position and drive the rotating rod 8 to rotate. The rotating rod 8 drives the screw 10 to rotate through the bevel gear pair, causing the limiting cylinder 11 to move downward and disengage from the groove. Then, any one of the bolts 13-2 can be rotated. The bolt 13-2 drives the connected second gear 13-3 to rotate, and the second gear 13-3 drives the first gear 13-1 to rotate, and the crossbar 14 is used to... The transmission with the bevel gear pair enables the synchronous rotation of several bolts 13-2, causing the locking plate 5 to move forward and disengage from the mounting plate 4. Once the bolts 13-2 have disengaged from the fixing cylinder 13-4, the locking plate 5 can be pulled forward to disengage the bolts 13-2 from the through hole of the mounting plate 4. Then, the base plate 2 and mounting plate 4 can be moved forward to disengage the mounting plate 4 from the mounting opening and the fixing cylinder 13-4, completing the removal of the base plate 2 from the mounting bracket 1. The new base plate 2 can then be installed. The mounting plate 4 abuts against the mounting opening, and the fixing cylinder 13-4 is inserted into the through hole on the mounting plate 4. Then, the locking pressure plate 5 is pushed backward, so that the rear end of the bolt 13-2 abuts against the threaded hole of the fixing cylinder 13-4. Then, any one of the bolts 13-2 is rotated in the opposite direction. With the cooperation of the first gear 13-1, the second gear 13-3 and the crossbar 14, the synchronous rotation of several bolts 13-2 is achieved. At this time, the rear end of the bolt 13-2 rotates into the fixing cylinder 13-4 through the thread, and the locking pressure plate 5 and the mounting plate 4 abut against the through hole. The mounting plate 4 abuts against each other, thereby limiting the mounting plate 4 and completing the installation of the base plate 2 on the fixing frame 1. Afterwards, the control plate 9 can be flipped forward to an inclined state. The control plate 9 drives the rotating rod 8 to rotate. The rotating rod 8 drives the screw 10 to rotate through the bevel gear pair, so that the limiting cylinder 11 moves upward and inserts into the groove, thereby limiting the locking pressure plate 5. By using the limiting cylinder 11 to limit the locking pressure plate 5, the bolt 13-2 can always be kept in a limited state, preventing the bolt 13-2 from loosening and rotating.

[0036] Compared with the prior art, the beneficial effects of this utility model are:

[0037] The locking mechanism 13, consisting of gear 13-1, gear 13-3, bolt 13-2, and fixing cylinder 13-4, works in conjunction with the linkage structure of crossbar 14 and bevel gear pair to achieve synchronous rotation of multiple bolts 13-2, which significantly improves the loading and unloading efficiency of base plate 2. At the same time, the limiting cylinder 11 effectively prevents the bolts 13-2 from loosening by limiting the locking pressure plate 5, ensuring the long-term stability of base plate 2 installation.

[0038] The convenient disassembly and assembly mechanism 15, composed of polygonal block 15-1, locking block 15-3, pressing rod 15-2 and gear 15-4, allows for quick replacement of the pneumatic suction cup 7 by pressing. Combined with the automatic reset function of spring 15-6, the efficiency of suction cup replacement is greatly improved. At the same time, the meshing design of gear 15-4 and rack 15-5 ensures the synchronous movement of locking blocks 15-3 on both sides, avoiding jamming during disassembly and assembly.

[0039] By setting a limiting mechanism that links the control plate 9, the rotating rod 8 and the screw 10, and using the limiting cylinder 11 to double lock the locking plate 5, the stability of the base plate 2 after installation is ensured, and it can be quickly unlocked through a simple flipping operation, which significantly improves the convenience and safety of the fixture.

[0040] The design of the guide rod 12 and the limiting block 16 ensures the smooth movement of the locking plate 5 and effectively prevents the guide rod 12 from accidentally coming out of the slot.

[0041] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
