Description

Technical Field

[0001] This utility model belongs to the field of packaging machine technology, and specifically relates to a resistor packaging machine. Background Technology

[0002] A resistor packaging machine is a device for spot-welding and packaging plate-type resistors. Existing resistor packaging machines use packaging tape as raw material to make bags, thereby packaging small parts such as resistors or LEDs.

[0003] Existing resistor packaging machines typically use a feeding mechanism to sequentially transport resistors onto a turntable. The rotation of the turntable then transports the resistors to the bottom of the packaging mechanism, where the packaging mechanism completes the packaging of the resistors.

[0004] However, in existing resistor packaging machines, the turntable cannot adjust the orientation of the resistors, resulting in resistors being transported to the packaging mechanism in different directions, which affects the packaging efficiency. At the same time, the turntable is usually equipped with a groove to restrict the movement of the resistors, which affects the packaging of the resistors.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a resistor packaging machine that can solve the problems of the turntable's inability to adjust the resistor orientation, which affects the resistor packaging efficiency, and the limitations imposed by the tank on the resistor, which affect the packaging of the resistor.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows: A resistor packaging machine includes a main body, a feeding mechanism, and an adjusting mechanism.

The adjusting mechanism consists of a pair positioned back-to-back at the edges of the rotating block. Each pair of adjusting mechanisms includes a pair of opposing adjusting plates positioned on the front and back sides of a corresponding suction nozzle.

Detailed Implementation

[0021] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0022] like Figures 1-7As shown, a resistor packaging machine according to one embodiment of the present invention includes a main body mechanism 1, a feeding mechanism 2, and an adjusting mechanism 3. The main body mechanism 1 includes a mounting platform 11, on which a feeding mechanism 12 and a packaging mechanism 13 are mounted in a relatively opposite manner on the left and right edges. The feeding mechanism 2 includes a rotating block 21 mounted rotatably on the mounting platform 11, which is located between the feeding mechanism 12 and the packaging mechanism 13. The rotating block 21 has a chamber 22 inside, and multiple suction nozzles 23 are provided on the rotating block 21 at equal intervals. A negative pressure conveying component is installed at the bottom of the rotating block 21. The adjusting mechanism 3 has a pair of adjusting plates 31 arranged in a front-back manner on the edge of the rotating block 21. Each pair of adjusting mechanisms 3 includes a pair of adjusting plates 31 arranged in a relatively opposite manner. The pair of adjusting plates 31 are located on the front and back sides of the corresponding suction nozzles 23. An adjusting component for adjusting the spacing of the pair of adjusting plates 31 is installed on the mounting platform 11.

[0023] When using this resistor packaging machine, the spacing between a pair of adjusting plates 31 is first adjusted by the adjusting component so that the spacing between the pair of adjusting plates 31 is slightly larger than the width of the resistor. Then, negative pressure is provided into the rotating block 21 by the negative pressure conveying component, so that the chamber 22 is in a negative pressure state. Then, the resistors to be packaged are sequentially conveyed onto the rotating block 21 by the feeding mechanism 12. When the resistor falls onto the rotating block 21 from the end of the feeding mechanism 12, the bottom of the resistor is attracted by the negative pressure through the suction nozzle 23 located at the bottom of the feeding mechanism 12, so as to temporarily fix the resistor. When the rotating block 21 rotates, it can drive the resistor to rotate. When the resistor rotates and contacts the pair of adjusting plates 31, the inner wall of the adjusting plates 31 comes into contact with the resistor. This contact causes the resistor to rotate under the suction of the nozzle 23, allowing the adjusting plates 31 to orient the resistor so that its width direction is between the pair of adjusting plates 31. This movement of the resistor between the adjusting plates 31, in turn, causes the rotating block 21 to rotate, thus moving the resistor. The pair of adjusting plates 31 completes the orienting of the resistor, ensuring that the resistors conveyed to the packaging mechanism 13 are aligned, thereby improving the packaging efficiency of the resistors. Simultaneously, the suction of the nozzle 23 limits the resistor's position by suction, exposing the entire resistor to the rotating block 21, facilitating packaging by the packaging mechanism 13 and further improving packaging efficiency.

[0024] like Figures 3-5 As shown, a vent pipe 24 is fixedly connected to the bottom of the rotating block 21. The lower end of the vent pipe 24 passes through the mounting platform 11 and is placed on the lower side of the mounting platform 11. The vent pipe 24 is rotatably connected to the mounting platform 11. The vent pipe 24 is used to provide negative pressure gas into the rotating block 21. The vent pipe 24 is rotatably mounted on the mounting platform 11 so that the vent pipe 24 can rotate with the rotating block 21 on the mounting platform 11.

[0025] like Figure 5 As shown, the vent pipe 24 is located on the side wall below the mounting platform 11 and has multiple air inlets 25. An air supply ring 26 is rotatably connected to the side wall of the platform 14 outside the multiple air inlets 25. This allows the air supply ring 26 and the vent pipe 24 to rotate relative to each other, while the vent pipe 24 and the air supply ring 26 are sealed to prevent vacuum leakage.

[0026] like Figure 1 and Figure 5 As shown, a negative pressure pipe 27 is fixedly connected to the side wall of the air supply ring 26, and a pressure regulating valve 28 is provided on the negative pressure pipe 27. The negative pressure pipe 27 is connected to the negative pressure device so that the air supply pipe 24 is in a negative pressure state through the air supply ring 26. The pressure regulating valve 28 is used to adjust the negative pressure so that the suction nozzle 23 can limit and fix the resistor, while the adjustment plate 31 can move the resistor to rotate under the suction of the suction nozzle 23, thereby adjusting the position of the resistor by the adjustment plate 31.

[0027] like Figures 3-5 As shown, the lower end of the vent pipe 24 is closed, and a stepper motor 29 is installed at the lower end of the vent pipe 24. The stepper motor 29 drives the vent pipe 24 to rotate, and the stepper motor 24 can be started and stopped at a certain angle to drive the rotating block 21 to rotate at the arc between adjacent suction nozzles 23, so as to realize the suction nozzles 23 sequentially limit and package the resistor.

[0028] like Figure 4 As shown, multiple balls 210 are installed between the mounting platform 11 and the rotating block 21. Annular tracks for installing the balls 210 are provided on the opposite side walls of the mounting platform 11 and the rotating block 21. The balls 210 ensure that the rotating block 21 is stable when it rotates on the mounting platform 11.

[0029] like Figure 2 As shown, a pair of adjusting plates 31 form an adjusting channel with a gradually narrowing spacing from left to right. Protective layers 37 are installed on the opposite sidewalls of each pair of adjusting plates 31. When the rotating block 21 conveys the resistor, the resistor moves from the wide opening to the narrow opening of the pair of adjusting plates 31. The gradually narrowing spacing between the adjusting plates 31 adjusts the direction of the resistor. The protective layers 37 prevent damage to the resistor when the adjusting plates 31 adjust its direction.

[0030] Preferably, a pair of adjusting plates 31 are provided on both the front and rear sides of the rotating block 21, so that the direction of the resistor can be adjusted regardless of whether the rotating block 21 rotates clockwise or counterclockwise.

[0031] like Figures 1-4 As shown, the adjustment assembly includes a mounting bracket 32, the vertical rod of which is fixedly connected to the mounting platform 11, and the horizontal rod of which extends into the rotating block 21.

[0032] like Figure 6 and Figure 7 As shown, a groove 33 is provided at the bottom of the horizontal bar of the mounting bracket 32. A pair of sliders 34 are slidably connected in the groove 33. One end of the pair of sliders 34 is located outside the groove 33 and is fixedly connected to the top of a pair of adjustment plates 31. When the pair of sliders 34 slide in the groove 33, they can drive the pair of adjustment plates 31 to move.

[0033] like Figure 6 and Figure 7 As shown, a bidirectional lead screw 35 is rotatably connected within the slide groove 33. A pair of sliders 34 are threaded onto the positive and negative threads of the bidirectional lead screw 35, respectively. One end of the bidirectional lead screw 35 extends to the outside of the mounting bracket 32 ​​and is fixedly connected to a rotating handle 36. When the bidirectional lead screw 35 is rotated by rotating the rotating handle 36, it drives the pair of sliders 34 to move closer to or further away from each other, thereby moving the pair of adjusting plates 31 closer to or further away from each other, thus adjusting the distance between the pair of adjusting plates 31. Adjusting the distance between the pair of adjusting plates 31 so that the nozzle 23 is positioned between the pair of adjusting plates 31 makes it easier to adjust the direction of the resistor.

[0034] It should be noted that since this application does not involve technical improvements to the feeding mechanism 12 and the packaging mechanism 13, the specific methods used by the feeding mechanism 12 and the packaging mechanism 13 to convey and package the resistors are all existing technologies and will not be elaborated here. Simultaneously, the feeding mechanism 12 and the packaging mechanism 13 are synchronized by the motor 29 driving the rotating block 21 to achieve synchronized feeding and packaging, as well as feeding during the intervals between feeding and packaging. Both packaging and feeding control are controlled by a single-chip microcomputer or other control system, which is existing technology and will not be elaborated here.

[0035] In use, firstly, rotating the bidirectional lead screw 35 drives a pair of sliders 34 to slide within the groove 33, adjusting the spacing of a pair of adjusting plates 31 so that the spacing is slightly larger than the width of the resistor. Then, negative pressure gas is supplied to the vent pipe 24 through the negative pressure pipe 27, creating a negative pressure state inside the rotating block 21. Simultaneously, the pressure regulating valve 28 adjusts the position of the suction nozzle 23 to fix the resistor without affecting the orientation of the adjusting plates 31. Then, the feeding mechanism 12 sequentially feeds the resistors to be packaged onto the rotating block 21. When the resistor falls onto the rotating block 21 from the end of the feeding mechanism 12, the bottom of the resistor is attracted by the negative pressure through the suction nozzle 23 located at the bottom of the feeding mechanism 12. To temporarily fix the resistor, the rotating block 21 rotates, causing the resistor to rotate as well. When the resistor rotates and contacts the pair of adjusting plates 31, the inner wall of the adjusting plates 31 contacts the resistor. Through this contact, the resistor rotates under the suction of the nozzle 23, causing the adjusting plates 31 to adjust the resistor's orientation so that its width direction is between the pair of adjusting plates 31. This allows the resistor to move between the pair of adjusting plates 31, and the rotation of the rotating block 21 causes the resistor to move. The pair of adjusting plates 31 can thus adjust the orientation of the resistor, ensuring that the resistors conveyed to the packaging mechanism 13 are aligned, thereby improving the packaging efficiency of the resistors. Simultaneously, the suction of the nozzle 23 limits the resistor's position by suction, exposing the entire resistor to the rotating block 21, facilitating packaging by the packaging mechanism 13 and further improving the packaging efficiency.
