Technical Field

[0001] The utility model relates to the technical field of bending machines, in particular to a zener diode bending machine. Background Art

[0002] A zener diode is a special surface contact type semiconductor silicon diode, which has the function of stabilizing voltage. By means of process measures in the manufacturing process and restricting the magnitude of the reverse current during use, it can ensure that the zener diode will not be damaged due to overheating in the reverse breakdown state. Before the zener diode is welded to the circuit board, the pins at both ends need to be bent at 90 degrees.

[0003] When the existing bending equipment bends a diode, usually after bending one side of the pin at 90 degrees, then bending the other side of the pin at 90 degrees. It cannot ensure that the pins at both ends of the diode are bent at 90 degrees at the same point, resulting in the bending angles of the two pins being inconsistent with respect to the diode tube end face, so that the pins cannot be opposite to the welding jack positions of the circuit board, which is not conducive to the welding of the diode.

[0010] For a voltage stabilizing diode bender of the present utility model, the base provides an installation condition for the remaining mechanisms. There is a voltage stabilizing diode placement groove on the placement table.

Detailed Embodiments

[0015] The first embodiment of the present application is as follows:

[0016] Please refer to Figure 1 , Figure 1It is a structural schematic diagram of the present utility model. The voltage stabilizing diode bender in this embodiment includes a base 101, a placement table 102, a pressing plate, a top rod 103, a bending block 104, and a driving rod. The pressing plate includes a pressing plate body 105, a rubber pad 106, a magnetic attraction block 107, and a lifting rod 108. The driving rod includes a transmission group 109, a screw rod 110, and a sleeve 111. Through the foregoing solution, the problem that the existing bending equipment cannot ensure bending at the same point position, resulting in inconsistent bending angles of the two pins from the end face of the diode, can be solved. It can be understood that the foregoing solution can be used in the scenario of diode bending.

[0017] For this specific embodiment, the placement table 102 is fixedly connected to the base 101 and is located on the top of the base 101. The pressing plate is arranged on one side of the placement table 102. The top rod 103 is fixedly connected to the pressing plate and is located on both sides of the pressing plate. The driving rod is arranged on both sides of the placement table 102. The bending block 104 is fixedly connected to the driving rod and is located on the side of the driving rod away from the placement table 102. The base 101 provides an installation condition for the rest of the mechanism. The placement table 102 has a voltage stabilizing diode placement groove. When the voltage stabilizing diode is placed in the placement groove, the bending positions of the two ends of the pins are at the same distance from the end face of the voltage stabilizing diode. When bending the pins of the voltage stabilizing diode, the worker places the voltage stabilizing diode on the placement table 102 by hand and places the pressing plate on the top of the placement table 102 to press the voltage stabilizing diode tightly. At this time, the driving member is started through the controller. The driving member operates to push the bending block 104 to rise, so as to cooperate with the top rod 103 to bend the two pins of the voltage stabilizing diode at the same time, thereby ensuring that the bending positions of the pins of the voltage stabilizing diode are at the same distance from the end face of the voltage stabilizing diode, and solving the problem that the existing bending equipment cannot ensure bending at the same point position, resulting in inconsistent bending angles of the two pins from the end face of the diode.

[0018] Among them, the pressing plate body 105 is arranged on one side of the placement table 102. The rubber pad 106 is fixedly connected to the pressing plate body 105 and is located on the side of the pressing plate body 105 close to the placement table 102. The magnetic attraction block 107 is fixedly connected to the pressing plate body 105 and is located on the side of the pressing plate body 105 close to the rubber pad 106. The lifting rod 108 is fixedly connected to the pressing plate body 105 and is located on the side of the pressing plate body 105 away from the rubber pad 106. The magnetic attraction block 107 is used to firmly adsorb the pressing plate body 105 on the placement table 102, so that the pressing plate body 105 firmly presses the voltage stabilizing diode. The setting of the rubber pad 106 is used to protect the voltage stabilizing diode to prevent the voltage stabilizing diode from being damaged by the pressing plate body 105. The setting of the lifting rod 108 facilitates lifting the pressing plate body 105 after the voltage stabilizing diode is bent.

[0019] Secondly, the screw rod 110 is rotatably connected to the placing table 102 and is located on one side of the placing table 102. The sleeve 111 is sleeved on the side of the screw rod 110 away from the placing table 102. The transmission group 109 is arranged on one side of the screw rod 110. The transmission group 109 includes a driving motor, a driving wheel, a driven wheel and a belt. The transmission group 109 drives the driving wheel through the driving motor. The driving wheel drives the belt to rotate, and the belt drives the driven wheel to rotate, so that the two screw rods 110 rotate, and further the sleeve 111 drives the bending block 104 to rise and bend the pins of the voltage stabilizing diode.

[0020] Consistently, when bending the pins of the voltage stabilizing diode, the worker places the voltage stabilizing diode on the placing table 102 by hand, and places the pressing plate body 105 on the top of the placing table 102 to press the voltage stabilizing diode tightly. It is adsorbed and fixed on the placing table 102 through the magnetic attraction block 107. At this time, the transmission group 109 is started through the controller. The transmission group 109 drives the screw rod 110. The rotation of the screw rod 110 makes the sleeve 111 rotate. Under the action of the thread, the sleeve 111 moves upward on the screw rod 110, and further pushes the bending block 104 to rise, and cooperates with the ejector rod 103 to bend the two pins of the voltage stabilizing diode at the same time, thus ensuring that the bending position of the pins of the voltage stabilizing diode is at the same distance from the end face of the voltage stabilizing diode, and solving the problem that the existing bending equipment cannot ensure bending at the same point, resulting in inconsistent bending angles of the two pins from the end face of the diode tube.

[0021] The second embodiment of the present application is as follows:

[0022] On the basis of the first embodiment, please refer to Figure 2 , Figure 2 which is the front view of the utility model. The voltage stabilizing diode bender of this embodiment further includes a moving component, and the moving component includes a sliding frame 201 and a telescopic pull rod 202.

[0023] For this specific embodiment, the moving component is arranged at the bottom of the base 101. The arrangement of the moving component facilitates the movement of the bender.

[0024] Among them, the sliding frame 201 is fixedly connected to the base 101 and is located at the bottom of the base 101. The telescopic pull rod 202 is fixedly connected to the sliding frame 201 and is located on one side of the sliding frame 201. The arrangement of the sliding frame 201 facilitates the movement of the bender. The arrangement of the telescopic pull rod 202 facilitates the worker to pull the sliding frame 201.

[0025] When the mobile component is in use, the worker stretches the telescopic pull rod 202 with his hand and pulls the telescopic pull rod 202 to one side, thereby providing a pulling force to the sliding frame 201. Under the action of the bottom pulley, the sliding frame 201 can slide on the ground, thereby realizing the movement of the bending machine.

[0026] The above-disclosed is only a preferred embodiment of a voltage regulator diode bending machine of the present application, and the scope of rights of the present application cannot be limited thereby. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
