Description

Technical Field

[0001] This utility model relates to the field of potentiometer technology, and specifically to a small potentiometer terminal assembly machine. Background Technology

[0002] A potentiometer typically consists of a resistive element and a movable brush (also called a contact point or slider). As the brush moves along the resistive element, a resistance value or voltage that is related to the amount of displacement can be obtained at the output terminal.

[0003] Currently, potentiometers are generally equipped with three terminals. When connecting the terminals to the potentiometer, an assembly machine is usually used. However, the current assembly machines have complex structures and use a large number of complex mechanisms such as robotic arms, resulting in large equipment size and high cost, which cannot be adapted to personal or small studio use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a small potentiometer terminal assembly machine that is small in size and can quickly position the potentiometer body and wiring terminals, so as to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a small potentiometer terminal assembly machine, including an assembly base, multiple potentiometer bodies and terminals. The assembly base is provided with multiple assembly slots, each with a channel communicating with the outside on one side. Each assembly slot has a positioning slot on its open end face, and multiple slots are vertically provided on one side of each positioning slot. Each assembly slot has a push plate inside. The potentiometer bodies are placed into the assembly slots and are in contact with the push plates. The circuit boards on the potentiometer bodies are inserted into the positioning slots, and the terminals are inserted into the slots. One end of each terminal is bent and in contact with the solder joint on the circuit board. The assembly base is provided with operating components for lifting the potentiometer bodies and pressing the terminals.

[0006] As a preferred technical solution, the operating components include a cylinder, a pressure plate, a push rod, and multiple side rods. The pressure plate is arranged parallel to the assembly base, and the inner side of the pressure plate abuts against the wiring terminal. The push rod is fixedly connected to multiple push plates. The side rods are respectively arranged at both ends of the assembly base. One end of each side rod is fixedly connected to the push rod, and the other end is slidably connected to the pressure plate. The middle of the push rod protrudes to form a fixing part. The cylinder is installed on the outer side of the assembly base, and the piston rod of the cylinder is connected and fixed to the fixing part.

[0007] As a preferred technical solution, the end of the push rod near the pressure plate protrudes to form a connecting part, and the inner side of the connecting part is provided with a sliding groove. Both ends of the pressure plate are equipped with sliders, and the sliders are slidably disposed in the sliding grooves.

[0008] As a preferred technical solution, the width of the channel is smaller than the inner diameter of the assembly slot.

[0009] As a preferred technical solution, the length and width of the terminal block cross-section match the length and width of the slot cross-section.

[0010] As a preferred technical solution, the pressure plate, push rod, and side rod are all made of metal.

[0011] The advantages of this utility model are: the utility model has a simple structure, small size, and convenient operation. The potentiometer body can be placed into the assembly slot, and the wiring terminals can be inserted into the slot. The descending pressure plate can press the wiring terminals tightly against the solder joints of the potentiometer body to ensure stability during subsequent soldering. After soldering is completed, the potentiometer body can be automatically lifted, which facilitates disassembly and assembly. Attached Figure Description

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0018] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0019] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses a small potentiometer terminal assembly machine, including an assembly base 3, multiple potentiometer bodies 1, and terminals 2. The assembly base 3 is provided with multiple assembly slots 13, each with a channel 4 communicating with the outside on one side. Each assembly slot 13 has a positioning slot 12 on its open end face, and multiple slots 11 are vertically provided on one side of each positioning slot 12. Each assembly slot 13 has a push plate 10 inside. Each potentiometer body 1 is placed into the assembly slot 13 and is in contact with the push plate 10. The circuit board on the potentiometer body 1 is inserted into the positioning slot 12, and each terminal 2 is inserted into the slot 11. One end of each terminal 2 is bent and in contact with the solder joint on the circuit board. The assembly base 3 is provided with operating components for lifting the potentiometer body 1 and pressing the terminal 2.

[0021] In this embodiment, the operating components include a cylinder 9, a pressure plate 8, a push rod 5, and multiple side rods 6. The pressure plate 8 is arranged parallel to the assembly base 3, and the inner side of the pressure plate 8 abuts against the wiring terminal 2. The push rod 5 is fixedly connected to multiple push plates 10. The side rods 6 are respectively arranged at both ends of the assembly base 3. One end of each side rod 6 is fixedly connected to the push rod 5, and the other end is slidably connected to the pressure plate 8. The middle part of the push rod 5 protrudes to form a fixing part. The cylinder 9 is installed on the outer side surface of the assembly base 3, and the piston rod of the cylinder 9 is connected and fixed to the fixing part.

[0022] In this embodiment, the push rod 5 protrudes at one end near the pressure plate 8 to form a connecting part 7. The inner side of the connecting part 7 is provided with a sliding groove 14. Both ends of the pressure plate 8 are equipped with sliders, which are slidably disposed in the sliding groove 14.

[0023] In this embodiment, the width of the channel 4 is smaller than the inner diameter of the assembly slot 13, which prevents the potentiometer body from moving outward along the channel.

[0024] In this embodiment, the length and width of the cross-section of the terminal 2 match the length and width of the cross-section of the slot 11 to ensure stability after the terminal is inserted and to avoid swaying.

[0025] In this embodiment, the pressure plate 8, push rod 5, and side rod 6 are all made of metal, which increases the rigidity and thus can better press the terminal block.

[0026] When in use, first place the potentiometer body into the assembly slot until it contacts the push plate, then push the pressure plate along the slide to move the pressure plate away from the top of the slot. At this time, the terminal can be inserted into the slot, and one end of the terminal can be placed on the circuit board solder joint of the potentiometer body.

[0027] After the above is completed, the pressure plate can be pushed back to move above the terminal block. After the cylinder is activated, the piston rod of the cylinder will retract and drive the push rod, push plate, side rod and pressure plate to descend until the circuit board on the potentiometer body is inserted into the positioning groove. The pressure plate can press down on the terminal block to press the terminal block and the circuit board together, and also press the potentiometer body together to ensure stability during subsequent soldering.

[0028] After welding is completed, the pressure plate can be pushed again and the cylinder can be activated, causing the piston rod of the cylinder to extend. The extension of the piston rod drives the push rod and push plate. The rising push plate can push all the internal potentiometer bodies out of the assembly slot at once, greatly increasing the efficiency of installation and disassembly.

[0029] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
