Description

Technical Field

[0001] The invention belongs to the technical field of PCB board processing, and in particular relates to a clamping fixture capable of double-sided processing of a PCB board. Background Art

[0002] PCB, the full name of which is Printed Circuit Board, is one of the most important components in the electronics industry. It is the support for electronic components and also the provider of electrical connections for electronic components.

[0003] After the PCB board is produced, it is necessary to weld the external cables to the pads on the surface of the PCB board according to the specific needs of subsequent use. When welding the cables to the pads on the surface of the PCB board, a clamping jig is usually used to fix the PCB board to facilitate welding of the PCB board. However, the clamping jig in the prior art usually uses a clamping plate to directly clamp and fix the four side walls of the PCB board, so that the pads on the upper and lower sides of the PCB board are exposed to the outside, which is convenient for processing the PCB board. However, some shorter side walls of the PCB boards have slots at both ends. At this time, the clamping plate is used to fix the side walls of the PCB board with the slots. The area when the clamping plate contacts the side wall of the PCB board with the slot is small, resulting in a large clamping force required to fix the PCB board. However, a large clamping force can easily damage the PCB board. At the same time, the longer side walls of the PCB board at both ends will have multiple trapezoidal installation openings that are convenient for subsequent installation. At this time, when the clamping plate is used to fix the longer side walls of the PCB board, the thinner part of the installation opening will directly contact the clamping plate. At this time, the clamping force of the clamping plate can easily cause the thinner part of the installation opening to break, causing damage to the PCB board, greatly reducing the reliability and stability of the PCB board during welding.

[0004] To this end, we propose a clamping fixture that can process PCB boards on both sides to solve the above problems. Summary of the invention

[0035] Specifically, when the PCB board needs to be processed, the inclination angle of the slot clamp 1015 can be adjusted according to the inclination angle of the inner wall of the slot provided on the shorter end side walls of the PCB board, so as to facilitate fixing the inner wall of the slot and avoid damage to the PCB board due to the large clamping force when the side wall of the PCB board with the slot is directly fixed by the clamp.

[0036] The operating principle of the present invention is now described as follows:

[0037] In the present invention, when welding processing is required on the surface of the PCB board, firstly, the shorter side walls of the PCB board at both ends are placed on one side of the two second side plates 106, and then the fifth motor 1013 is controlled to start, driving the support rod 1012 to rotate. During the rotation of the support rod 1012, the seventh electric telescopic rod 1014 and the card slot clamping plate 1015 are driven to rotate. When the inclination angle of the card slot clamping plate 1015 is the same as the inclination angle of the inner wall of the corresponding PCB board card slot, the fifth motor 1013 is controlled to be turned off, and then the third electric slide rail 107 is controlled to start, driving the third slide plate 108 to move. After the card slot clamping plate 1015 is located on one side of the corresponding card slot, the third electric slide rail 107 is controlled to be closed, and then the fifth electric telescopic rod 102 and the sixth electric telescopic rod 108 are controlled to be moved. 104 is started, driving the corresponding two second side plates 106 to move, so that the connecting rod 109 drives the card slot clamping plate 1015 to enter the corresponding card slot, and then the seventh electric telescopic rod 1014 is controlled to start, driving the card slot clamping plate 1015 to move, and the card slot clamping plate 1015 is used to fix the inner wall of the card slot opened on the shorter side wall of the PCB board, so as to complete the fixation of the shorter end side wall of the card slot clamping plate 1015, and then the second electric slide rail 94 is controlled to start, driving the second slide plate 95 to move, so that the U plate 97 moves to the top of the PCB board, and then the first electric slide rail 91 is controlled to start, driving the first slide plate 92 to move, so that the U plate 97 moves to the side of the trapezoidal installation opening opened on the longer end side wall of the PCB board, and then the second motor 99 is controlled to start, driving the first round rod 98 rotates, and during the rotation of the first round rod 98, the first side plate 910 is driven to rotate. After the inclination angle of the first side plate 910 is the same as the inclination angle of the inner walls at both ends of the corresponding trapezoidal mounting opening, the inclination angle of the first clamping plate 912 is the same as the inclination angle of the inner walls at both ends of the trapezoidal mounting opening. Then, the first electric telescopic rod 96 is controlled to start, driving the first clamping plate 912 and the second clamping plate 914 to move. After the first clamping plate 912 and the second clamping plate 914 are located directly above the trapezoidal mounting opening, the second electric slide rail 94 is controlled to start the second slide plate 95 to move downward, so that the first clamping plate 912 and the second clamping plate 914 are located inside the trapezoidal mounting opening. Then, the second electric telescopic rod 911 is controlled to start, driving the first clamping plate 912 to move. A clamping plate 912 fixes the inner walls at both ends of the trapezoidal installation opening, and then the third electric telescopic rod 913 is controlled to start, driving the second clamping plate 914 to move, so that the side wall of the second clamping plate 914 conflicts with the front inner wall of the trapezoidal installation opening, and the inner groove clamping plate 917 is located inside the inner groove opened on the front inner wall of the trapezoidal installation opening, and then the fourth electric telescopic rod 916 is controlled to start, driving the inner groove clamping plate 917 to move, and the inner groove clamping plate 917 is used to fix the inner wall of the inner groove opened on the front inner wall of the trapezoidal installation opening, thereby fixing the inner wall of the installation opening opened on the longer side wall of the PCB board. At this time, the PCB board is fixed, and then the staff first performs welding processing on the upper surface of the PCB board. After the welding processing on the upper surface of the PCB board is completed,The first motor 6 is controlled to start, and the second gear 5 is driven to rotate, so that the second gear 5 drives the first gear 4 meshing with it to rotate, thereby driving the rotating ring 3 to rotate, so that the two mounting plates 8 drive the PCB board to rotate, and at the same time, the third motor 103 and the fourth motor 105 are controlled to rotate, and the fifth electric telescopic rod 102 and the sixth electric telescopic rod 104 are driven to rotate, so that the PCB board rotates, and the rotation speed of the fifth electric telescopic rod 102 and the sixth electric telescopic rod 104 is the same as the rotation speed of the two mounting plates 8. After the PCB board is rotated 180 degrees, the lower surface of the PCB board faces upward, which is convenient for welding the lower surface of the PCB board, thereby realizing double-sided welding of the PCB board. When the PCB board needs to be processed, the slot clamp 1 can be adjusted according to the inclination angle of the inner wall of the slot provided on the shorter end side walls of the PCB board. The inclined angle of 015 is convenient for fixing the inner wall of the card slot, avoiding the damage of the PCB board caused by the large clamping force when the clamping plate is directly used to fix the side wall of the PCB board with the card slot. At the same time, the inclined angle of the first clamping plate 912 can be adjusted according to the inclined angle of the inner walls at both ends of the trapezoidal installation opening opened by the longer side walls of the PCB board, so that the first clamping plate 912 can be used to fix the inner walls at both ends of the trapezoidal installation opening. At the same time, the inner groove clamping plate 917 can be used to fix the inner wall of the inner groove opened by the front inner wall of the trapezoidal installation opening, avoiding the clamping force of the clamping plate when the clamping plate is used to fix the longer side wall of the PCB board, which easily causes the thinner part of the installation opening to break, resulting in damage to the PCB board, facilitating the subsequent processing of the PCB board, and greatly improving the reliability and stability of the welding processing of the PCB board.
