Description

Technical Field

[0001] The invention relates to the technical field of resistor production and manufacturing, and in particular to an automatic assembly machine for double-pin terminal. Background Art

[0002] Cement resistors are commonly used electronic components and are widely used in many fields. They are made by winding the resistor wire on a non-alkali heat-resistant porcelain piece, fixing it with heat-resistant, moisture-resistant and corrosion-resistant materials, and filling and sealing it with special resin heat-resistant cement. Cement resistors are widely used in power adapters, audio equipment, audio crossovers, instruments, meters, televisions, cars and other equipment.

[0003] The function of cement resistor is the same as that of general resistor, but it can be used in occasions with large current, such as being connected in series with the motor to limit the starting current of the motor, and the resistance value is generally not large. Its packaging is generally horizontal and vertical. Cement resistor has many characteristics, such as shock resistance, moisture resistance, heat resistance, good heat dissipation, low price, etc.; completely insulated, suitable for printed circuit boards; excellent heat resistance, small resistance temperature coefficient, linear change; short-term overload resistance, low noise, and resistance value does not change over the years; good explosion-proof performance, protective effect.

[0004] Normally, cement resistors generally include a ceramic rod resistor unit encapsulated in a ceramic shell. The ceramic rod resistor unit consists of a ceramic rod and terminals assembled at both ends of the ceramic rod. The terminals usually have pins or legs. The assembly between the terminal and the ceramic rod is usually achieved by a capping machine. The existing capping machine is mainly for ceramic rod resistor units with pins or legs axially arranged on the terminal. When the pins or legs are perpendicular to the ceramic rod and are arranged unidirectionally, it is necessary to manually load, clamp and position the material on the fixture, then start the capping action, and finally manually unload the material, resulting in low production efficiency and unstable quality.

A manual adjustment wheel 521 is provided at one end of the driving spindle 55.

[0069] Optionally, a protective cover 14 is provided corresponding to the side transmission shaft 59 , the side transmission shaft seat 510 and the transverse driving cam 511 .

[0070] Optionally, an adjustable supporting foot 17 is provided at the lower end of the main frame 11. In addition, a control panel 13 is also provided on one side of the main frame 11. The control panel 13 is electrically connected to the porcelain rod feeding mechanism 20, the terminal horizontal feeding mechanism 30, the assembly actuator 40, and the assembly drive mechanism 50.

[0071] like Fig.13 As shown, initially, the terminal vibration disk 31 and the straight vibration feeder 39 are started to ensure that there are continuously foot terminals in the terminal discharge slot 381. At the same time, the porcelain rod vibration disk 21 is started to continuously transport porcelain rods to the feed head 24, the clamping drive cylinder contracts, and the clamping nozzle 28 is in an open state.

[0072] Then, the driving motor starts to drive the driving main shaft 55, the side transmission shaft 59, the lateral driving cam 511, the discharge cam 57, and the rotation sensing component 518 to rotate, and the discharge cam 57 drives the discharge swing shaft 513 to swing back and forth, and the terminal discharge plate 418 and the extrusion die 41 move synchronously. When the terminal discharge plate 418 and the extrusion die 41 move to the initial position, at this time, the terminal discharge plate 418 opens upward, and the extrusion die 41 is connected to the discharge port of the terminal discharge groove 381, and the foot terminal enters the terminal bearing groove and is magnetically positioned; at the same time, the induction plate of the rotation sensing component 518 sends a feeding signal to the clamping nozzle 28, and the clamping drive cylinder extends to drive the clamping nozzle 28 to clamp the porcelain rod to the V-shaped position of the positioning block 217, and the clamping drive cylinder remains extended.

[0073] As the driving spindle 55 continues to rotate, the transverse driving cam 511 drives the transverse slider 413, the longitudinal driving arm 517 drives the longitudinal slider 49, and the material discharge driving block 515 drives the terminal material discharge plate 418, and the terminal material discharge plate 418 closes downward and keeps blocking the discharge port; the extrusion die 41 moves forward longitudinally and approaches the positioning block 217 laterally. When the extrusion die 41 reaches the transverse limit position, the terminal caps of the foot terminal in the terminal bearing groove are pressed against the two ends of the porcelain rod; at this time, the induction sheet of the rotating sensing component 518 sends a reset signal to the clamping nozzle 28 and sends a pushing signal to the pushing block 219; the clamping driving cylinder shrinks and retracts, and because the extrusion die 41 is pressed against the two ends of the porcelain rod at this time, the clamping tension spring is forced to open, so that the porcelain rod leaves the clamping nozzle 28; the reset signal and the pushing signal have a certain time difference, and within this time difference, as the driving spindle 55 rotates, the extrusion die 41 leaves and resets from the two ends of the positioning block, and the pushing cylinder is extended according to the pushing signal and resets, pushing the assembled porcelain rod from the positioning block to the receiving box below.

[0074] Repeat the above steps.

[0075] The automatic assembly machine for double-foot terminal of the embodiment of the present invention realizes automatic discharge and loading of foot terminal and porcelain rod by means of a vibration plate, adopts a clamping nozzle and a positioning block to position and hold the porcelain rod while forming an assembly station, and the driving spindle realizes automatic material picking, feeding, assembly and clamping of the foot terminal through an extrusion die and a terminal discharge plate under the cooperation of a cam transmission mechanism; the driving spindle only needs to cooperate with the clamping nozzle to automatically complete the assembly of the pressure caps of the foot terminal and the porcelain rod. The equipment control method is simple, stable and reliable, the mechanism coordination is precise and ingenious, and the operation is stable and efficient.
