Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of jigs, and in particular to a three-dimensional adjustable tin-planting jig. Background Technology
[0002] Existing soldering fixtures typically have chip positioning slots for placing chips and a support surface for placing soldering stencils. After the chip is placed in the chip positioning slot, the top surface of the chip is on the same plane as the support surface. Then, the soldering stencil is placed on top of the chip, with the edge of the soldering stencil on the support surface. The edge of the soldering stencil is pressed down by a pressure block, and then soldering can be performed on the chip. However, this soldering fixture is only suitable for soldering a single type of chip and has poor versatility. To solder chips of different lengths and thicknesses, it is necessary to produce or purchase corresponding soldering fixtures, which increases the cost of soldering. Utility Model Content
[0003] In order to overcome the existing technical defects, the purpose of this utility model is to provide a three-dimensional adjustable tin-planting fixture to solve the above-mentioned technical problems.
[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:
[0005] According to one aspect of this utility model, a three-dimensional adjustable solder placement fixture is designed, comprising: a base, a sliding seat, and a floating block. Two sliding seats are provided and are laterally slidably engaged with the base. One end of each of the two sliding seats is provided with a clamping block for clamping and fixing a chip. The floating block is located above the sliding seats and is connected to them by an adjusting bolt. An elastic element is provided between the two sliding seats to abut against them. The top surface of the clamping block is higher than the top surface of the floating block. When the adjusting bolt is turned, the distance between the top surface of the floating block and the top surface of the clamping block can be adjusted. One side or both sides of each sliding seat are provided with a locking component connected to the base and used to lock and fix the sliding seat. Each sliding seat is provided with a clamping component for pressing the end of the solder placement plate against the top of the clamping block.
[0006] Using the above technical solution, when the chip needs soldering, the two ends of the chip are placed on two floating blocks. The height of the floating blocks is then adjusted by turning the adjusting bolts with a screwdriver. Once the top surface of the chip is level with the top surface of the clamping block, the adjustment is complete. Then, the two sliding seats are moved towards each other, clamping the chip and fixing it in place. The sliding seats are then secured using a locking assembly. Next, the soldering plate is placed above the chip, with its end positioned on top of the clamping block. The mesh on the soldering plate is aligned with the soldering points on the chip. The soldering plate is then pressed down using a clamping assembly, securing it in place. Soldering can then be performed. The operation is seamless, as the two sliding seats slide against the base, allowing the distance between the two clamping blocks to be adjusted. This enables the clamping of chips of different lengths. By turning the adjusting bolt, the height of the floating block can be adjusted, thereby adjusting the height of the chip placed on top of the floating block. This ensures that the top surface of the chip is aligned with the top surface of the clamping block, facilitating subsequent soldering. Therefore, this soldering fixture can meet the needs of fixing and soldering chips of different lengths and thicknesses. For soldering different chip models, it eliminates the need to purchase multiple soldering fixtures, significantly reducing soldering costs. Furthermore, this fixture has a simple structure, is easy to adjust, and provides excellent performance.
[0007] To better address the aforementioned technical deficiencies, this utility model also offers a superior technical solution:
[0008] In some embodiments, an adjusting wheel is rotatably connected inside the base. The top of the adjusting wheel is provided with a spiral groove, and the bottoms of the two sliding seats are respectively fixed with columns. The columns pass through a transverse strip-shaped through hole provided on the base and are inserted into the spiral groove. Rotating the adjusting wheel can drive the two sliding seats to move closer or further apart. The position of the two sliding seats can be easily adjusted simultaneously using the adjusting wheel.
[0009] In some embodiments, each of the floating blocks is provided with an adjusting bolt at its front and rear ends, and two elastic elements are provided between each of the floating blocks and the sliding seat. The elastic elements are compression springs, with their upper ends inserted into blind holes on the floating blocks and their lower ends inserted into blind holes on the sliding seats.
[0010] In some embodiments, the upper end of the clamping block extends through a through-hole on the floating block to the top of the floating block.
[0011] In some embodiments, the locking assembly includes a pressure block and a locking screw, one end of the pressure block being located above the end of the sliding seat, and the lower end of the locking screw passing through a through hole on the pressure block and threadedly engaging with a threaded hole on the base.
[0012] In some embodiments, the clamping assembly includes a pressure plate, a rubber-headed screw, and a support member. The lower end of the rubber-headed screw passes through a strip hole on the pressure plate and is threaded into a threaded hole on the base. Rotating the pressure plate can move one end of it above the clamping block. The support member is located below the pressure plate and is fixedly connected to the base.
[0013] In some embodiments, the top surface of the floating block is higher than the top surface of the base, and an adjusting member for adjusting the position of the chip is movably inserted on the base. An adjusting and fixing assembly for pressing and fixing the adjusting member and connecting it to the base is provided above the adjusting member.
[0014] In some embodiments, an upper frame and a lower frame are provided above the base. The lower frame is positioned on top of the base and has a solder plate placement slot at its top. The lower end of the upper frame is placed in the solder plate placement slot, and a first magnetic block on the upper frame and a second magnetic block on the lower frame are vertically aligned and attract each other. Large-sized solder plates can be placed in the solder plate placement slot on the lower frame. After the solder plate is placed in the slot, the lower end of the upper frame is placed in the slot and pressed onto the solder plate. The solder plate is then fixed in place by the attraction between the first magnetic block on the upper frame and the second magnetic block on the lower frame, facilitating chip soldering and solder plate replacement. When the upper and lower frames are removed, other structures of this fixture can be used to fix and solder small-sized chips.
[0015] In some embodiments, a positioning post is provided on one of the lower frame and the base, and a positioning hole that mates with the positioning post is provided on the other.
[0016] In some embodiments, the upper frame is provided with connecting bolts, the lower ends of which pass through through holes in the upper frame and threadedly engage with threaded holes in the lower frame. When a small number of chips are soldered, the attraction between the first magnetic block on the upper frame and the second magnetic block on the lower frame is sufficient to fix the solder plate. When a large number of chips are soldered, the connecting bolts lock the upper and lower frames together, which can better fix the solder plate and avoid frequent removal and placement of the upper and lower frames, which could cause displacement of the solder plate and affect the soldering effect, thus ensuring the quality of soldering.

[0027] In the description of this utility model, unless otherwise explicitly defined, terms such as setting, installing, connecting, and fixing should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0028] refer to Figures 1 to 6As shown, the present invention provides a three-dimensional adjustable soldering fixture, comprising: a base 1, a sliding seat 2 and a floating block 3. There are two sliding seats 2, which are laterally slidably engaged with the base 1. Specifically, each sliding seat 2 has one or two or more transverse grooves 20 at its bottom, and the base 1 is provided with a transverse guide block 11 that is slidably engaged with the transverse grooves 20.
[0029] Two sliding seats 2 are respectively provided with clamping blocks 21 at their opposite ends. The clamping blocks 21 are integral with the sliding seats 2 or are fixed to the top of the sliding seats 2 by bolts. When the two sliding seats 2 move towards each other, the two sliding seats 2 drive the two clamping blocks 21 to move towards each other, which can clamp and fix the chip.
[0030] Two floating blocks 3 are provided, and the two floating blocks 3 are respectively located above the two sliding seats 2. The floating blocks 3 and the sliding seats 2 are connected by adjusting bolts 31, and elastic elements 4 are provided between them to abut against each other. Furthermore, each floating block 3 has an adjusting bolt 31 at its front and rear ends. The lower end of the adjusting bolt 31 passes through the countersunk hole on the floating block 3 and is threaded into the threaded hole on the sliding seat 2. Two elastic elements 4 are provided between each floating block 3 and the sliding seat 2. The elastic elements 4 are compression springs, with their upper ends inserted into the blind holes on the floating block 3 and their lower ends inserted into the blind holes on the sliding seat 2.
[0031] Tightening the adjusting bolt 31 can adjust the height of the floating block 3, thereby adjusting the distance between the top surface of the floating block 3 and the top surface of the clamping block 21.
