Abstract
Description
Technical Field
[0001] This utility model relates to the field of bending technology, and in particular to a bending machine. Background Technology
[0002] A digital tube is a type of display screen. By inputting relative currents to different pins on the digital tube, it lights up, thus displaying parameters that can be represented digitally, such as time, date, and temperature. Due to their low price and ease of use, digital tubes are widely used in electrical appliances, especially home appliances, such as air conditioners, water heaters, and refrigerators. To facilitate connecting the digital tube to the circuit board, the pins of the digital tube need to be bent to a suitable angle before connecting the digital tube to the circuit board.
[0003] The bending of digital tube pins is generally done using a bending machine. Existing bending machines use a pressure block with an inclined surface to achieve the bending. The pressure block is configured to move horizontally. During the movement of the pressure block, the pin is guided to bend by its inclined surface. However, during the movement of the pressure block, sliding friction will occur between it and the pin, which can easily cause friction damage to the pin surface. Utility Model Content
[0004] The purpose of this invention is to provide a bending machine that reduces frictional damage.
[0005] To achieve the above objectives, this utility model proposes a bending machine for bending the pins of a digital tube, comprising:
[0006] The positioning platform has at least one upward-opening positioning groove for positioning and placing a digital tube. The depth of the positioning groove is configured such that when the digital tube is placed in the positioning groove, the vertically extending pins of the digital tube protrude from the upper opening of the positioning groove. A bending guide is fixedly provided on the side of the positioning groove for guiding the pins to bend.
[0007] A bending device includes at least one bending unit that can move horizontally. A bending unit is disposed above a positioning groove. The bending unit is a pressure roller or a pair of two pressure rollers. The bending device also includes a lifting device and a horizontal moving device. The lifting device is used to control the lifting and lowering of the bending unit, and the horizontal moving device is used to drive the bending unit to move horizontally. The bending unit moves away from or closer to the digital tube by lifting and lowering, and the bending unit bends the pin by rolling by horizontal movement.
[0008] Preferably, the positioning groove is provided with several spaced-apart slots in a row, and the bending unit is also provided with several spaced-apart slots in a row accordingly.
[0009] Preferably, the positioning platform further includes a moving platform, and the bending guide is disposed on the moving platform. The moving platform drives the bending guide to move closer to or away from the positioning groove.
[0010] Preferably, a digital tube has two rows of pins, and two moving platforms are provided. The two moving platforms are located on the outside of the two rows of pins, and the bending guide is located at the inner end of the moving platform.
[0011] Preferably, the bending guide is an "L"-shaped bending edge.
[0012] Preferably, the bending guide includes an "L"-shaped guide groove.
[0013] Preferably, the positioning groove is provided with a hand latch groove, which is connected to the positioning groove and protrudes from the outer contour of the positioning groove.
[0014] Preferably, a digital tube has two rows of pins, the bending unit is a pair of two pressure rollers, and the horizontal moving device is used to drive the pair of two pressure rollers to move closer or further apart. The maximum width of the pair of two pressure rollers at the extreme position of moving closer to each other is less than the distance between the two rows of pins, so that the pair of two pressure rollers at the extreme position of moving closer to each other can be inserted into the gap between the two rows of pins.
[0015] Preferably, the pressure roller is provided with striped guide grooves, each guide groove corresponding to a pin setting.
[0016] The beneficial effects of this utility model are as follows:
[0017] This invention uses a rolling pressure roller, which bends the pins of the digital tube by rolling on a horizontal surface. This avoids friction damage to the pins during the bending process while ensuring that the bending angle and height of the pins are consistent. Attached Figure Description

[0024] The embodiments of this utility model are described in detail below. 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 intended to explain this utility model, and should not be construed as limiting this utility model. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the art or in accordance with the product manual.
[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0026] See Figure 1-6 As shown, in a preferred embodiment of this utility model, a bending machine is provided for bending the pin 1 of a digital tube. See reference. Figure 1 As shown, a digital tube has two rows of pins 1. When the digital tube is placed in the positioning slot, it extends vertically with pins 1 pointing upwards. Figure 2 The digital tube after pin 1 has been bent by a bending machine.
[0027] The bending machine in this embodiment includes a positioning platform 2 and a bending device 3. The positioning platform 2 is provided with an upward-opening positioning groove 21 for positioning and placing digital tubes. The positioning groove 21 has several grooves arranged in a row at intervals. (Continue reading) Figure 3 , Figure 3 The enlarged portion of the image shows the positioning groove 21 without a digital tube, while the other positioning grooves 21 are in the state where digital tubes are placed. The depth of the positioning groove 21 is configured such that when the digital tube is placed in the positioning groove 21, the vertically extending pins 1 of the digital tube protrude from the upper opening of the positioning groove 21. A bending guide 22 for guiding the pins 1 to bend is fixedly provided on the side of the positioning groove 21. The bending device 3 includes a bending unit 31 that can move in the horizontal direction. Several bending units 31 are also provided in a row with intervals, with one bending unit 31 positioned above a positioning groove 21. In this embodiment, the bending unit 31 is a pair of two pressure rollers. In other embodiments, it can also be set as a single pressure roller for bending a single row of pins 1. If it is necessary to bend both rows of pins 1 of the digital tube, the working efficiency of the bending unit with a single pressure roller will be greatly reduced.
[0028] The positioning platform 2 also includes a moving platform 23, on which a bending guide 22 is disposed. The movement of the moving platform 23 drives the bending guide 22 to move closer to or further away from the positioning groove 21. In this embodiment, the digital tube has two rows of pins 1, and correspondingly, two moving platforms 23 are provided. The two moving platforms 23 are located on the outer sides of the two rows of pins 1, and the bending guide 22 is located at the inner end of the moving platform 23. The bending guide 22 is used to guide the bending of the pins 1, ensuring that the bending angle and height of the pins are consistent, avoiding inconsistent bending angles and heights of the pins 1 on the same digital tube, which would make it difficult to solder the digital tube onto the circuit board, thus improving the yield rate of digital tube pin bending. In other embodiments, only one moving platform with a bending guide can be provided for bending a single row of pins of the digital tube.
[0029] The bending device 3 also includes a lifting device 32 and a horizontal moving device 33. The lifting device 32 controls the lifting and lowering of the bending unit 31, and the horizontal moving device 33 drives the bending unit 31 to move horizontally. The bending unit 31 moves away from or closer to the digital tube by lifting and lowering it, and the horizontal movement of the bending unit 31 bends the pins 1 by rolling. Bending the pins 1 by rolling avoids friction damage and improves the yield rate of the digital tube. A digital tube has two rows of pins 1. The bending unit 31 consists of a pair of pressure rollers. The horizontal moving device 33 drives the pair of pressure rollers to move closer or further apart. The maximum width of the pair of pressure rollers at their closest point is X (e.g., ...). Figure 5 (As shown in the diagram). The maximum width X of a pair of pressure rollers at their closest extreme positions is less than the spacing between the two rows of pins 1, allowing the pair of pressure rollers at their closest extreme positions to insert between the gaps of the two rows of pins 1, thus enabling better bending of the pins 1. The bending guide 22 has an "L"-shaped bending edge. To better bend the pins 1 of the digital tube, an "L"-shaped guide groove 24 can be further provided in the bending guide 22. Of course, the guide groove 24 can be omitted, but this may cause the pin bending direction to deviate, making it difficult to solder the digital tube onto the circuit board. Alternatively, striped guide grooves can be provided on the pressure rollers, with each guide groove corresponding to one pin, for better guiding the bending of the digital tube pins.
[0030] During the bending process of the bending machine, the digital tube with its pins 1 facing upwards is first placed in the positioning groove 21. The bending device 3 descends and approaches the positioning platform via the lifting device 32, positioning the bending unit 31 above the digital tube. Two pressure rollers are inserted between the gaps of the two pins of the digital tube. Simultaneously, the two moving platforms 23 move closer to each other in the horizontal direction, so that the bending guide 22 located at the inner end of the moving platform 23 is outside the two rows of pins 1. The horizontal moving device 33 drives the two pressure rollers to move away from each other in the horizontal direction, bending the pins 1 along the guide groove 24 on the bending guide 22 by rolling. After the pins 1 of the digital tube are bent, the two pressure rollers move closer to each other in the horizontal direction, and the bending device 3 moves away from the positioning platform 2 in the vertical direction. At the same time, the two moving platforms 23 drive the bending guide 22 to move away from each other in the horizontal direction, making it easier to remove the bent digital tube.
[0031] The bending machine in this embodiment can be used to bend multiple digital tubes simultaneously. In other embodiments, only one positioning slot and one bending unit corresponding to the positioning slot can be set in the positioning platform to miniaturize the bending machine in this embodiment, so that it can be placed on a desktop or other suitable location for independent use.
[0032] To facilitate the handling of the digital tubes, a handle groove 25 is provided on the positioning groove 21 in this embodiment. The handle groove 25 passes through the positioning groove 21 and protrudes from the outer contour of the positioning groove 21. The bending machine proposed in this embodiment allows manual placement of the digital tubes at the assembly position. In other embodiments, a robotic arm with a suction cup can be used to pick up the digital tubes and place them in the positioning groove 21 to achieve automation.
[0033] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention.
