Description
Technical Field
[0001] The utility model belongs to the technical field of transport jigs, and in particular relates to a damage-resistant PCBA transport jig. Background Art
[0002] PCBA stands for Printed Circuit Board Assembly. PCBA is a circuit board created by printing solder paste on a PCB and then installing various components such as resistors, integrated circuits, capacitors, and transformers based on the board's purpose and required characteristics. During production, printed circuit boards need to be moved from one processing facility to another, typically using a jig. Existing jigs are used to move printed circuit boards from one facility to another during production. These jigs are designed to clamp and secure them, ensuring a tighter fit and preventing them from falling or damaging.
[0003] When the existing handling jig is used to transport the assembled printed circuit board, it is necessary to move the adjusting clamp to clamp and fix the printed circuit board before transporting it. Moreover, when the printed circuit board is frequently clamped and fixed for transport, the bidirectional screw frequently rotates to move the movable seat on the outer surface of the bidirectional screw and drive the clamp to move and clamp it. This makes it inconvenient to lubricate the outer surface of the screw, so that the movable seat generates a certain amount of friction when moving on the outer surface of the bidirectional screw. In severe cases, the threaded structure on the surface of the bidirectional screw is even damaged by friction and cannot be used anymore, thereby affecting the convenience of the handling jig for lubricating the bidirectional screw when the printed circuit board is transported, clamped and fixed. For this reason, the utility model proposes an anti-damage PCBA handling jig. Utility Model Content

The two movable seats 107 drive the two clamping plates 104 to move toward each other so that the end of the printed circuit board contacts the flexible rubber plate 105 and squeezes and clamps it. When clamping, the flexible rubber plate 105 is deformed and pressurized to reinforce the installation to prevent it from falling off, which is not easy to cause the printed circuit board to fall and be damaged after clamping. It is convenient to prevent damage during transportation. The handling fixture body 100 is also provided with:

The end of the drainage brush 1087 is in contact with the outer surface of the bidirectional screw rod 108, so that when the bidirectional screw rod 108 is rotated to drive the movable seat 107 to move, the drainage brush 1087 is in contact with the outer surface of the bidirectional screw rod 108 to drain and inject lubricating oil, which facilitates the oiling and lubrication process and is not prone to friction damage.
[0031] A reinforcing support mechanism is provided, and the reinforcing support mechanism includes a reinforcing support component arranged on the inner side of the clamping plate 104. A limited sliding component is provided at the connection between the end of the reinforcing support component and the lower surface of the base plate 101. When the clamping plate 104 is moved to clamp and fix the printed circuit board for transportation, the reinforcing support mechanism can strengthen the support connection of the clamping plate 104, and it is not easy to be skewed when clamped and fixed under force, thereby improving the support stability of the transport jig body 100 when the printed circuit board is assembled, clamped, fixed and transported.

When the reinforcing support rod 1041 is moved and clamped following the splint 104, the end of the reinforcing support rod 1041 drives the slide seat 1043 to slide and support on the outer surface of the slide rail 1044, thereby stabilizing the sliding support clamping operation.
[0034] The working principle and use process of the present invention are as follows: when using the anti-damage PCBA handling jig, first the handling jig body 100 is fixedly installed at the end of the driving device at the processing position through the mounting plate 102. After the handling jig body 100 is installed, when the printed circuit board is assembled, the base plate 101 is moved to the position of the printed circuit board through an external driving device, and the forward and reverse motors 103 are driven to drive the driving gear 106 to rotate and engage with the outer surface of the driven gear 109 to drive the bidirectional screw rod 108 to rotate. The bidirectional screw rod 108 rotates to move the two moving seats 107 toward each other, and the two moving seats 107 drive the two clamping plates 104 to move toward each other to contact the end of the printed circuit board with the flexible rubber plate 105 and squeeze and clamp it. When clamping, the flexible rubber plate 105 is deformed and pressurized to reinforce the installation to prevent it from falling off, which is not easy to cause the printed circuit board to fall and be damaged after clamping. It is convenient to prevent damage during transportation and easy to use the handling jig body 100 to assemble and transport the printed circuit board.
[0035] Then, when the transport jig body 100 is clamped and fixed, the clamping plate 104 drives the reinforcing support rod 1041 to move when it moves, thereby driving the slide 1043 to slide on the outer surface of the slide rail 1044 through the end of the reinforcing support rod 1041, so that the clamping plate 104 is frequently moved, clamped and fixed by the reinforcing support rod 1041 to strengthen the support connection, and it is not easy for the clamping plate 104 to be slightly deformed and skewed when clamped and subjected to force, and the connection is always strengthened for stable clamping, installation and transportation, thereby improving the support stability of the transport jig body 100 when the printed circuit board is assembled, clamped, fixed and transported;
[0036] Finally, before the handling fixture body 100 is used, the drainage brush 1087 is elastically pressed and fixed to the inside of the mesh plate 1085 through the elastic mounting tube 1086, and the drainage brush 1087 is fixed to the end of the movable seat 107 again through the arc plate 1082, so that the drainage brush 1087 contacts the surface of the bidirectional screw rod 108, and after the fixed installation, the lubricating oil is injected into the oil storage tank 1083 through the oil filling port 1084 through the connecting hole 1081, and the sealing cover is rotated at the end of the oil filling port 1084, and the bidirectional screw rod 108 is rotated to drive the movable seat When 107 moves on the outer surface of the bidirectional screw rod 108, the lubricating oil inside the oil storage tank 1083 is drained to the outer surface of the bidirectional screw rod 108 through the drainage brush 1087, which is convenient for draining and lubricating the outer surface of the bidirectional screw rod 108, so that the bidirectional screw rod 108 drives the moving seat 107 for lubrication when rotating, and drives the clamping plate 104 to clamp and fix the printed circuit board, which is not easy to cause friction damage to the outer surface of the bidirectional screw rod 108, thereby improving the convenience of oiling and lubricating the bidirectional screw rod 108 when the handling fixture body 100 is used to transport, clamp and fix the printed circuit board.
