Description

Technical Field

[0001] The utility model relates to the technical field of SMT patches, in particular to a SMT patch production fixture. Background Art

[0002] SMT patch refers to the abbreviation of a series of process flows based on PCB. SMT is surface mount technology (surface mount technology), which is the most popular technology and process in the electronic assembly industry. When SMT patch processing and production is performed on PCB, the PCB needs to be fixed, so a fixture is needed. After the PCB is clamped and fixed on the fixture, the components can be assembled using assembly equipment.

[0003] In the existing clamp structure for SMT patches, although the clamp can be adjusted in the horizontal direction and is suitable for clamping PCBs of different sizes, it cannot obtain effective buffering and tightening during the clamping process. When the clamping force is too small, the clamping stability of the PCB cannot be guaranteed. When the clamping force is too large, it is easy to cause damage to the PCB, thereby affecting the production effect. Moreover, after clamping, the vertical limit fixation cannot be performed, which easily causes the PCB to tilt or loosen during assembly, affecting the assembly effect. The structure is simple and the use effect is average. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-Figure 5 As shown, an SMT patch production fixture includes a base 1, a connecting seat 2 is provided on the base 1, and a connecting rod 3 is provided between the connecting seats 2, a clamping seat 4 is provided on the connecting rod 3, a placement groove 5 is provided on the clamping seat 4, and a tightening structure 6 is provided on the clamping seat 4, and a pressing structure 7 is provided on the clamping seat 4, a servo motor 8 is installed on the base 1 and the connecting seat 2, and a bidirectional screw rod 9 is provided between the connecting seats 2, the bidirectional screw rod 9 is connected to the servo motor 8, a circular hole 10 and a threaded hole 11 are provided on the clamping seat 4, and the clamping seat 4 is installed on the connecting rod 3 through the circular hole 10, and the bidirectional screw rod 9 runs through the threaded hole 11.

[0021] When performing SMT patch, the fixture is placed on the patch device, and the base 1 ensures that the entire fixture is placed stably. The clamping structure 6 and the pressing structure 7 are installed on the clamping seat 4, and then the PCB is clamped and fixed. When clamping, the servo motor 8 is started, and the servo motor 8 rotates with the bidirectional screw rod 9, thereby driving the clamping seat 4 to move along the connecting rod 3 until the symmetrically arranged clamping seats 4 are located in a suitable position, and the PCB is placed between the clamping seats 4 to ensure that the edge of the PCB enters the placement groove 5. Then the servo motor 8 is started again to drive the two clamping seats 4 to continue to move closer until the PCB is clamped and fixed. At this time, the PCB is fixed by the pressing structure 6, and then the patch device is started. The corresponding components can be assembled on the PCB using the patch device. When necessary, the pressing structure 7 can also be used to clamp and fix the PCB, so that the PCB is subjected to forces in both vertical and horizontal directions at the same time, thereby ensuring stability during the assembly process.

[0022] Through the above implementation scheme, the clamping structure 6 includes a clamping plate 601 and a connecting component 603, the clamping plate 601 is connected to the connecting component 603, and the clamping plate 601 is located in the placement groove 5, the clamping structure 6 also includes an inclined plate 602 and a spring 604, the inclined plate 602 is fixed to the end of the clamping plate 601, the spring 604 is sleeved on the connecting component 603, and the ends of the spring 604 contact the clamping plate 601 and the clamping seat 4 respectively, the connecting component 603 includes a connecting head 6031, a movable rod 6032 and a threaded joint 6033, the connecting head 6031 is fixed on the clamping plate 601, the movable rod 6032 and the threaded joint 6033 are fixedly connected, and the threaded joint 6033 is threadedly connected to the connecting head 6031, and the clamping structure 7 includes a screw 701 and a rubber block 703, the rubber block 703 is connected to the lower end of the screw 701, and the screw 701 is threaded. The groove is connected to the clamping seat 4, and the clamping structure 7 also includes a clamping head 702 and an adjusting wheel 704. The clamping head 702 is fixed to the lower end of the screw 701, and the rubber block 703 is sleeved on the clamping head 702. The adjusting wheel 704 is fixed to the upper end of the screw 701. A placement groove 5 is arranged on the clamping seat 4, which is used in conjunction with the tightening structure 6 to play a tightening role, so that when the PCB is clamped, even if the clamping force is too large or too small, it will not cause damage to the PCB. The PCB can be effectively clamped and fixed when passing through, and the stability of subsequent processing is guaranteed. A connecting component 603 is arranged in the tightening structure 6, which is convenient for disassembling the tightening structure 6 and improves the operational flexibility. The clamping structure 7 is installed on the clamping seat 4, and the PCB can also be clamped and fixed in the vertical direction, further ensuring the stability of the PCB after clamping, and avoiding loosening of the PCB during assembly.

[0023] When installing the clamping structure 6, place the clamping plate 601 in the placement groove 5, pass the movable rod 6032 through the clamping seat 4, sleeve the spring 604 on the part of the movable rod 6032 located in the placement groove 5, screw the threaded joint 6033 onto the connector 6031, and thus complete the installation of the clamping structure 6. When clamping the PCB, the clamping plate 601 first contacts the edge of the PCB. As the clamping seat 4 continues to move, the clamping plate 601 moves relative to the clamping seat 4 through the connecting assembly 603, thereby compressing the spring 604. In this way, it is possible to avoid the situation where the clamping force is too large or too small, ensure that the clamping effect on the PCB is just right, and prevent damage to the PCB. When installing the clamping structure 7, a rubber block 703 is sleeved on the clamping head 702, and the screw 701 is screwed onto the clamping seat 4. When the clamping structure 7 needs to be used, the screw 701 is rotated by the adjusting wheel 704, and the screw 701 descends with the rubber block 703 until the rubber block 703 is pressed onto the PCB, and then the assembly work can be carried out. The structure is simple and the use effect is excellent.
