Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, specifically a manual crimping fixture. Background Technology

[0002] A circuit board is a plate-shaped structure composed of an insulating substrate and a conductive copper layer. Conductors are formed by etching to connect components such as resistors, capacitors, and chips. During the circuit board manufacturing process, components need to be pressed onto the circuit board.

[0003] Currently, when pressing parts onto circuit boards, the usual method is to first place the parts on the circuit board at the desired pressing position, and then manually press them down to assemble them. This process is labor-intensive and can easily damage the product if the pressing pressure is misaligned. Utility Model Content

[0004] The purpose of this invention is to provide a manual crimping fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a manual pressing fixture, comprising a base and a pressing assembly. Foot pads are installed at the four corners of the base's bottom. The pressing assembly is located on the top of the base and includes a bracket, a first connecting rod, a quick-release handle, a second connecting rod, a pressing rod, a guide sleeve, a lifting seat, and a pressing head. The top of the base is fixed with a bracket, and the upper end of the bracket is rotatably connected to the first connecting rod. A quick-release handle is installed on one side of the end of the first connecting rod, and the other side of the end of the first connecting rod is rotatably connected to the second connecting rod. The lower part of the second connecting rod is rotatably connected to the pressing rod, and a guide sleeve is fitted onto the outer circumference of the pressing rod. A lifting seat is installed at the bottom of the pressing rod, and a pressing head is installed at the bottom of the lifting seat.

[0006] Furthermore, the base has a width of 400mm and a length of 450mm.

[0007] Furthermore, a positioning component is provided on the top of the base, and the positioning component includes a positioning groove and a material picking groove. The positioning groove is provided on the top of the base, and material picking grooves are provided on both sides of the positioning groove.

[0008] Furthermore, the material feeding trough is rectangular and has a depth of 5mm.

[0009] Furthermore, the positioning assembly also includes a connecting shaft, a spring, and a positioning block. The four corners of the positioning groove are provided with connecting shafts, and the upper outer side of the connecting shaft is fitted with a spring, and the bottom of the spring is connected to a positioning block.

[0010] Furthermore, the positioning block is slidably connected to the connecting shaft, and the connecting shaft is rotatably connected to the base.

[0011] Furthermore, sliders are installed at both ends of the lifting seat, and a guide rail is slidably connected to one side of the slider.

[0012] Furthermore, the guide sleeve is fixedly connected to the bracket, and the bracket is fixedly connected to the guide rail.

[0013] This utility model provides a manual crimping fixture, which has the following beneficial effects: This invention, through the setting of the pressing assembly, allows for easy placement of circuit boards. Simply lift the quick push handle to rotate it around the upper end of the first connecting rod, which in turn pulls the pressure rod via the second connecting rod, causing the lifting seat to move upward. This provides a larger placement space below. After placing the circuit board and components, simply press down the quick push handle to squeeze the pressure rod via the second connecting rod, causing it to move under the guidance of the guide sleeve. This allows the pressure head to quickly press the components onto the circuit board, improving the convenience of pressing. At the same time, the slider and guide rail guide the lifting seat to prevent skewing during force application, thus improving the yield rate during pressing. 2. This utility model, through the setting of the positioning component, can quickly limit the circuit board by using the positioning groove to prevent the circuit board from being skewed. At the same time, the spring can push the positioning block under the limit of the connecting shaft to press the four ends of the circuit board, thereby improving the convenience of positioning the circuit board. When removing it, you only need to rotate the positioning block to separate it from the circuit board, and then use the material picking groove to easily apply force to the side of the circuit board, which is also very convenient during unloading.

Figure 1 , Figure 2 and Figure 3 The structure shown first involves lifting the quick-release pusher 403, causing it to rotate around the upper end of the first connecting rod 402. This, in turn, pulls the pressure rod 405 via the second connecting rod 404, causing the lifting seat 407 to move upward. Next, the circuit board is placed in the positioning groove 301, quickly positioning it to prevent tilting. Simultaneously, the spring 304, under the constraint of the connecting shaft 303, pushes the positioning block 305 to press the four ends of the circuit board, improving the ease of positioning. Then, after placing the circuit board and the parts to be pressed... After the component is removed, simply press down the quick push handle 403 to squeeze the pressure rod 405 through the second connecting rod 404, causing it to move under the guidance of the guide sleeve 406. This allows the pressure head 408 to quickly press the component onto the circuit board, improving the convenience of pressing. At the same time, the slider 5 and the guide rail 6 guide the lifting seat 407 to prevent tilting when applying force. Finally, when removing the component, first lift the quick push handle 403, then rotate the positioning block 305 to separate it from the circuit board, and then use the material retrieval slot 302 to easily pick up and unload the side of the circuit board.
