Description

TECHNICAL FIELD

[0001] The application relates to the technical field of pin trimming, and particularly relates to a high-frequency power supply pin trimming machine. BACKGROUND

[0002] With the rise of new energy vehicles, the power supply industry has developed rapidly, thereby producing a large number of power batteries to meet the increasing demand of people for new energy vehicles. In the production process of the power supply, a process is to trim the pins of the power supply, so that the pins of the power supply can be conveniently handled and installed in the subsequent process, and the power supply can normally function.

[0003] A conventional pin trimming machine for the power supply is generally composed of a trimming device, a transmission device, a control device and an adjusting device. In the use process, an operator can set the length of the reserved pin through the adjusting device according to the need, and then the control device starts the transmission device to drive the power supply to move. In the process, the trimming device can trim the pins of the power supply at one time, thereby completing the pin trimming operation. The pin trimming machine has the advantages of simple structure, convenient use and low cost, and is the most widely used pin trimming machine at present.

[0004] Although the current pin trimming machine has the above-mentioned advantages, it still has certain limitations in the use process. For example, the trimming device cannot trim the pins at one time, and the operator cannot directly find the existence of the problem. The power supply with untrimmed pins will enter the next handling and installation process. The long pins will cause the power supply function to be unstable after installation, resulting in the problem of inconvenient use. To solve the above-mentioned problems, the application file proposes a high-frequency power supply pin trimming machine. SUMMARY

[0006] Further, the support device comprises a stroke sleeve fixedly installed on the top of the base near the four corners, the inside of the stroke sleeve is movably installed with a stroke rod through telescopic cooperation, the outer surface of the stroke rod is fixedly installed with annular limiting sheets near the top through welding, the number of the annular limiting sheets is four and they are distributed in a way of two in a group, the outer surface of the stroke rod between the annular limiting sheets is fixedly installed with a connecting bracket through clamping, one side of the connecting bracket is fixedly installed with a connecting sheet through bolt connection, and the guide rail is connected with one side of the connecting sheet through bolt fixation.

[0007] Further, the material of the connecting sheet is a metal material capable of being deformed.

[0008] Further, the elastic device comprises a support rod fixedly installed on the top of the base through bolt fixation, the outer surface of the support rod is provided with threads through lathe tapping, and is movably sleeved with an adjusting bolt through the threads, the top of the adjusting bolt is provided with an annular groove through milling, and the inside of the annular groove is movably sleeved with a spring rotating seat, the top of the spring rotating seat is fixedly installed with a return spring through clamping, the top of the return spring is fixedly connected with the stroke device, the top of the support rod is fixedly installed with a connecting rod through welding, and the top of the connecting rod is fixedly installed with a circular truncated cone top seat through welding.

[0009] Further, the circular truncated cone top seat is movably installed with the stroke device through shaft hole cooperation, the cross section of the circular truncated cone top seat is in the shape of a circular truncated cone and the diameter of the bottom is smaller than that of the top, and the cross section diameter of the connecting rod is smaller than that of the circular truncated cone top seat and the support rod.

[0010] Further, the stroke device comprises a baffle, the bottom of the baffle is fixedly installed with a bearing frame near the inside of the two ends through welding, the outer surface of one side of the bearing frame is fixedly installed with a stroke plate near the bottom through welding, the top of the stroke plate is provided with a return conical hole through drilling bed drilling, and the return conical hole is movably installed with the circular truncated cone top seat through shaft hole cooperation.

[0011] Further, the return spring is connected with the bottom of the stroke plate through clamping, and the connecting position is located at the back side of the return conical hole (the specific position is a in the attached drawings of the specification). Figure 11

[0012] The present application has the following beneficial effects.

[0013] ​1. The connecting piece is made of a deformable metal material. The stroke sleeve has a stroke rod installed inside through a telescopic fit, which allows for displacement margin in the double-layer track formed by the guide rail. As the vibrator runs and drives the energy-conducting disk to vibrate, it will drive the track guide rail to rotate synchronously. By controlling the direction and intensity of the vibration, the high-frequency power supply located on the double-layer track guide rail can be moved along the extension direction of the guide rail, ensuring that the high-frequency power supply can move to the stroke device, ensuring that the subsequent shearing operation can be carried out smoothly, and improving the reliability of the device during operation.

[0014] 2. The high-frequency power supply located at the top of the guide rail continuously advances along the extension direction of the guide rail under the drive of the vibrating machine and the energy guiding plate. It then contacts the top of the stroke plate. At this time, under the influence of its own weight, the stroke device moves vertically downward, reducing the height of the high-frequency power supply. Simultaneously, the telescopic machine raises the height of the shearing machine, allowing the pins at the bottom of the high-frequency power supply to insert into the shearing machine. The shearing machine then cuts the pins at the bottom of the high-frequency power supply. The cut high-frequency power supply continues to advance along the extension direction of the guide rail due to the vibration of the guide rail. As the overall height of the stroke device decreases, the cut high-frequency power supply enters the lower track formed by the guide rail. The stroke device resets under the elastic force of the return spring as the high-frequency power supply leaves, ensuring that subsequent high-frequency power supplies can continue to contact the stroke plate during their advance, thus completing the cycle. This allows the entire shearing operation to be performed automatically without manual intervention, improving the automation of the device and reducing operating costs.

[0015] 3. When the entire travel device moves vertically downwards, the baffle will prevent the high-frequency power supply located on the upper track formed by the guide rails from continuing to advance. This avoids multiple high-frequency power supplies entering the top of the travel device, causing excessive load on the travel device and resulting in an excessive descent height. This would cause the pins of the high-frequency power supply to be too short after shearing, leading to incompatibility issues with the battery during subsequent processing and installation. It also prevents the high-frequency power supply from falling directly onto the top of the base and being damaged due to insufficient height after shearing, thus improving the stability of the device during operation.

[0016] 4. The outer surface of the support rod is threaded by tapping on a lathe, and an adjusting bolt is movably fitted through the thread. An annular groove is milled on the top of the adjusting bolt, and a spring rotating seat is movably fitted inside this groove. Rotating the adjusting bolt allows adjustment of the height of the spring rotating seat, thereby changing the initial elastic force of the return spring. Users can control the initial elastic force of the return spring according to the required pin length. If a longer pin length is required, the distance between the adjusting bolt and the top of the frustum can be shortened by screwing the adjusting bolt inward, increasing the initial elasticity of the return spring. When the high-frequency power supply moves to the top of the travel plate, the overall descent distance of the travel device decreases, thus shortening the pin length cut by the shearing machine and increasing the required pin length. Conversely, if a shorter pin length is required, the reverse operation increases the overall descent distance of the travel device, thus increasing the pin length cut by the shearing machine and decreasing the required pin length. This allows the device to be adjusted according to different user needs, broadening its applicability and improving its practicality.

[0017] 5. If the pins at the bottom of the high-frequency power supply are not completely cut during the shearing process, the shearing blades will not immediately separate after merging. Instead, they will separate after the telescopic conveyor drives the shearing machine to complete its reset. Therefore, the shearing machine will drag the pins at the bottom of the high-frequency power supply after shearing, breaking off the cut pins in this way, thus completing the pin cutting operation. If dragging still cannot break off the pins, the shearing machine will continue to drag the high-frequency power supply during the reset process until the shearing machine completes its reset and the reset spring is over-compressed and has a large elastic force. At this point, the shearing blades separate, and the elastic force of the reset spring acts directly on the high-frequency power supply and bounces it up. Since the reset spring is connected to the bottom of the travel plate by a snap-fit, the connection position is located behind the reset conical hole (the specific location is shown in the attached diagram of the instruction manual). Figure 11 (at point a in the diagram), and the cross-sectional diameter of the connecting rod is smaller than that of the frustum top seat and the support rod, resulting in a fit allowance between the reset conical hole and the connecting rod. Therefore, during the dragging process, the travel plate will tilt at a certain angle, causing the travel device to exert an upward force on the high-frequency power supply during the reset spring force reset process. This causes the high-frequency power supply to move upward at an angle and enter the upper track formed by the guide rail, thereby distinguishing between high-frequency power supplies that have not been properly clipped and those that have been properly clipped, facilitating subsequent processing by operators and improving the convenience of using the device.

Embodiment two

[0037] On the basis of embodiment one, the elastic device 6 comprises a support rod 61, which is installed on the top of the base 1 by a bolt fixing mode, the outer surface of the support rod 61 is provided with threads by a lathe tapping mode, and an adjusting bolt 62 is movably sleeved on the threads, the top of the adjusting bolt 62 is provided with a ring-shaped groove by a milling machine slotting mode, and a spring rotating seat 63 is movably sleeved in the ring-shaped groove, a return spring 64 is fixedly installed on the top of the spring rotating seat 63 by a clamping mode, the top of the return spring 64 is fixedly connected with the stroke device 7, a connecting rod 65 is fixedly installed on the top of the support rod 61 by a welding mode, and a circular truncated cone top seat 66 is fixedly installed on the top of the connecting rod 65 by a welding mode, the height of the spring rotating seat 63 can be adjusted by rotating the adjusting bolt 62, so that the initial elastic force of the return spring 64 is changed.

[0038] Please refer to Figure 1 and Figures 8-11 , under the influence of the self-weight, the stroke device 7 as a whole moves in the vertical downward direction, so that the height of the high-frequency power supply 10 is lowered, and the height of the shearing machine 5 driven by the telescopic machine 4 is raised, so that the pins at the bottom of the high-frequency power supply 10 are inserted into the inside of the shearing machine 5, at this time, the shearing machine 5 shears the pins at the bottom of the high-frequency power supply 10, the sheared high-frequency power supply 10 continues to move along the extension direction of the track guide 3 due to the vibration of the track guide 3, and since the height of the stroke device 7 as a whole has been lowered, the sheared high-frequency power supply 10 enters the lower track formed by the track guide 3, and the stroke device 7 resets under the elastic force of the return spring 64 as the high-frequency power supply 10 leaves, so that the subsequent high-frequency power supply 10 can continue to contact the stroke plate 73 during movement, thereby completing the cycle, so that the entire foot shearing operation can be automatically performed without manual intervention, the automation of the device is improved, and the use cost is reduced. Embodiment three

[0039] On the basis of embodiment two, the circular truncated cone top seat 66 and the stroke device 7 are movably installed in a shaft hole matching mode, the cross section of the circular truncated cone top seat 66 is in a circular truncated cone shape, and the bottom diameter is smaller than the top diameter, and the cross section diameter of the connecting rod 65 is smaller than the cross section diameters of the circular truncated cone top seat 66 and the support rod 61.

[0040] The stroke device 7 comprises a baffle plate 71, the bottom of which is fixedly installed with a bearing frame 72 through welding at a position close to the inner two ends, the outer surface of the bearing frame 72 is fixedly installed with a stroke plate 73 through welding at a position close to the bottom, the top of the stroke plate 73 is provided with a reset conical hole 74 through drilling, and the reset conical hole 74 is movably installed with the circular table top base 66 through shaft hole cooperation. When the stroke device 7 moves in the vertical downward direction, the baffle plate 71 will block the high-frequency power supply 10 on the upper track formed by the guide rail 3 from continuing to move forward.

[0041] Please refer to Figure 1 and Figures 8-11 , so as to avoid multiple high-frequency power supplies 10 from entering the top of the stroke device 7, causing the stroke device 7 to bear too much weight and the stroke device 7 to drop too much, causing the pins of the high-frequency power supply 10 to be too short after being cut by the shearing machine 5, causing the battery to be unable to adapt during subsequent processing and installation, and also avoiding the problem that the high-frequency power supply 10 cannot normally enter the lower track formed by the guide rail 3 due to the low height, causing the high-frequency power supply 10 to directly fall onto the top of the base 1 and be damaged, thereby improving the stability of the device during operation. Embodiment Four

[0042] On the basis of embodiment three, the reset spring 64 is connected to the bottom of the stroke plate 73 through clamping, and the connection position is located at the rear side of the reset conical hole 74 (the specific position is a in the Figure 11 of the accompanying drawings).

[0043] The user can control the initial elasticity of the reset spring 64 according to the specific pin length required, if the required pin length is longer, the initial elasticity of the reset spring 64 can be increased by rotating the adjusting bolt 62 to shorten the distance between the adjusting bolt 62 and the circular table top base 66, so that the distance of the overall descent of the stroke device 7 is reduced when the high-frequency power supply 10 moves to the top of the stroke plate 73, thereby shortening the pin length cut by the shearing machine 5, achieving the effect of increasing the pin length reserved by the high-frequency power supply 10, if the required pin length is shorter, the overall descent distance of the stroke device 7 can be increased through reverse operation, thereby increasing the pin length cut by the shearing machine 5, achieving the effect of reducing the pin length reserved by the high-frequency power supply 10, so that the device can be adjusted according to the different needs of the user, has a wider application range, and improves the practicality of the device. Embodiment Five

[0044] On the basis of embodiment four, please refer to Figure 1 and Figures 5-11When the pins at the bottom of the high-frequency power supply 10 are not completely cut during the shearing process, the blades of the shearing machine 5 will not immediately separate after merging, but will separate after the telescopic machine 4 drives the shearing machine 5 to complete the reset. Therefore, the shearing machine 5 will drag the pins at the bottom of the high-frequency power supply 10 after shearing, and break the pins that form the cut in this way, thus completing the pin cutting operation. If dragging still cannot break the pins, the shearing machine 5 will continue to drag the high-frequency power supply 10 during the reset process until the shearing machine 5 completes the reset, and the reset spring 64 has been over-compressed and has a large elastic force. At this time, the blades of the shearing machine 5 separate, and the elastic force of the reset spring 64 directly acts on the high-frequency power supply 10 and bounces it up. Since the reset spring 64 is connected to the bottom of the travel plate 73 by a snap-fit, the connection position is located on the rear side of the reset conical hole 74 (the specific position is shown in the attached diagram of the instruction manual). Figure 11 (at point a in the diagram), and the cross-sectional diameter of the connecting rod 65 is smaller than that of the frustum top seat 66 and the support rod 61, so there is a fit allowance between the reset conical hole 74 and the connecting rod 65. Therefore, during the dragging process, the stroke plate 73 will tilt at a certain angle, so that the stroke device 7 will generate an upward force on the high-frequency power supply 10 during the spring force reset of the reset spring 64, thereby causing the high-frequency power supply 10 to move upward and enter the upper track formed by the guide rail 3. This distinguishes the high-frequency power supply 10 that has not been properly clipped from the high-frequency power supply 10 that has been properly clipped, making it easier for operators to carry out subsequent processing and improving the convenience of using the device.
