Description

Technical Field

[0001] This application relates to the field of strapping machines, and in particular to a horizontal pushing device for a battery strapping machine frame. Background Technology

[0002] Horizontal strapping machines are generally used for packaging new energy batteries. As one of the core pieces of equipment in the field of automated packaging, horizontal strapping machines are widely used in logistics, warehousing, manufacturing, and agricultural product processing industries. Their core function is to use mechanical structures to drive straps (such as PP or PET straps) around the product, completing the sealing process through heat sealing or snap-fit ​​methods, thereby improving transportation stability, reducing breakage rates, and optimizing storage space utilization.

[0003] In the key actuators of horizontal strapping machines, the driving accuracy of the drive frame (used for product positioning) and the strapping track (used for conveying straps) directly affects the strapping quality. Current mainstream technologies use pneumatic or hydraulic cylinders to directly drive the frame or track, thereby achieving displacement.

[0004] Regarding the aforementioned technologies, the stroke and movement speed of the frame and track are directly limited by the cylinder or hydraulic cylinder, thus improving the tolerance for repeatability of the cylinder and hydraulic cylinder. Utility Model Content

[0005] The purpose of this application is to provide a horizontal pushing device for a battery strapping machine frame.

[0006] This application provides a horizontal pushing device for a battery strapping machine frame, which adopts the following technical solution:

[0007] A horizontal pushing device for a battery strapping machine frame includes:

[0008] Mounting plate for fixed connection to the frame and / or rails, and laterally sliding connection to the rack;

[0009] The first drive rod has its lower end hinged to the frame and its upper end tilted in the direction of the forward movement of the mounting plate.

[0010] The lower end of the second drive rod is hinged to the upper end of the first drive rod, and the other end is hinged to the mounting plate.

[0011] A power source for driving the first drive rod to swing;

[0012] The power source drives the first drive rod to swing, increasing the tilt angle of the first drive rod, which in turn causes the second drive rod to move the mounting plate forward.

[0013] By adopting the above technical solution, the tilting setting of the first drive rod allows it to swing and push the mounting plate. In the initial stage, it rapidly amplifies the swing angle of the power source (such as the extension and retraction of a cylinder piston rod) to achieve a large stroke displacement of the mounting plate. As it approaches the target position, the increased tilt angle slows down the rate of increase in lateral displacement, achieving a "soft landing" type of precise positioning. In traditional direct drive solutions, the displacement of the mounting plate is linearly related to the output of the power source. In this solution, the power source only needs to control the swing angle. As the swing angle increases, the displacement per unit angle decreases, thus improving the tolerance for repeated positioning accuracy of the power source.

[0014] Optionally, the second drive rod is inclined, and its inclination direction is opposite to that of the first drive rod.

[0015] By adopting the above technical solution, during the process of pushing the mounting plate, the second drive rod is subjected to tension, and the tensile properties of the material are better than its compressive properties.

[0016] Optionally, when the mounting plate moves forward to the stop position, the tilt angle between the second drive rod and the mounting plate is 40°~50°.

[0017] By adopting the above technical solution, the lateral component of the second drive rod within this angle range is close to the vertical component, which reduces the force exerted on the mounting plate during the pushing process, further achieving "soft landing" type precise positioning, and providing more options when selecting a power source, rather than having to choose a power source with precise thrust control.

[0018] Optionally, the second drive rod is a threaded adjusting rod with adjustable length.

[0019] By adopting the above technical solution, it is easy to adjust the stroke of the mounting plate and the tilt angle of the second drive rod.

[0020] Optionally, the power source includes a cylinder or a hydraulic cylinder, one end of which is hinged to the frame and the other end is hinged to the first drive rod.

[0021] Optionally, the cylinder or hydraulic cylinder is hinged to the lower part of the first drive rod.

[0022] By adopting the above technical solution, it is possible to increase the stroke of the translation device.

[0023] Optionally, two sets of the first drive rod, the second drive rod, and the power source are provided, and they are located on both sides of the mounting plate, respectively.

[0024] By adopting the above technical solution, bidirectional synchronous drive ensures that the mounting plate is subjected to balanced force, eliminating the tilting error caused by unilateral drive.

[0025] Optionally, a limit switch is fixedly connected to the frame, and a baffle is fixedly connected to the mounting plate at the position corresponding to the limit switch. When the limit switch is triggered by contact with the baffle, the power source stops driving the first drive rod to deflect.

[0026] By adopting the above technical solution, the machine is stopped through hard contact between a mechanical baffle and a limit switch, improving reliability and avoiding malfunctions caused by electronic signal interference. The baffle position is adjustable to adapt to different travel requirements.

[0027] Optionally, the frame is threadedly connected to a screw, the position of which is parallel to the limit switch and corresponds to the position of the baffle.

[0028] By adopting the above technical solution, the physical travel and stopping points are determined. When the limit switch fails, it is used to protect the battery and effectively alleviate the problem of crushing.

[0029] Optionally, the mounting plate is slidably connected to the frame via a track pair.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. The tilting setting of the first drive rod allows it to swing and push the mounting plate. In the initial stage, it rapidly amplifies the swing angle of the power source (such as the extension and retraction of a cylinder piston rod) to achieve the large stroke displacement of the mounting plate. As it approaches the target position, the increased tilt angle slows down the rate of increase in lateral displacement, achieving a "soft landing" precise positioning. In traditional direct drive schemes, the displacement of the mounting plate is linearly related to the output of the power source. In this scheme, the power source only needs to control the swing angle. As the swing angle increases, the displacement per unit angle decreases, improving the tolerance for repeatability of the power source's positioning accuracy. A linkage mechanism with dual tilting drive rods (first drive rod + second drive rod) replaces the traditional direct drive of cylinders / hydraulic cylinders, achieving mechanical amplification and precise control of horizontal displacement.

[0032] 2. The first and second drive rods are tilted in opposite directions, and the tilt angle between the second drive rod and the mounting plate is 40°~50°, so that the lateral component of the second drive rod is close to the vertical component. During the pushing process, the force applied to the mounting plate is reduced, further realizing "soft landing" type precise positioning. When selecting a power source, there is more room for choice, rather than having to choose a power source with precise thrust control.

[0033] 3. A mechanical baffle is used to trigger a stop via hard contact with the limit switch, improving reliability and preventing malfunctions caused by electronic signal interference. The baffle position is adjustable to accommodate different travel requirements. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail below.

[0039] Specific embodiment: This embodiment relates to a horizontal pushing device for a battery strapping machine frame, referring to... Figure 1 and Figure 2 The device includes:

[0040] Mounting plate 1: Horizontally positioned, used to mount the frame and / or fixing rails. The frame is used to compress and secure the battery for subsequent bundling; the rails are used to thread cable ties. In this embodiment, both the frame and rails are mounted on mounting plate 1, and the bundling machine head is also mounted on mounting plate 1. Mounting plate 1 is laterally slidably connected to the frame 3 via linear rail pairs 2. When mounting plate 1 moves forward, the machine head approaches the battery to be packaged, while the frame simultaneously pushes and clamps the battery.

[0041] First drive rod 4: It is set at an angle, with its lower end hinged to the frame 3 and its upper end tilted in the direction of moving forward of the mounting plate 1;

[0042] The second drive rod 5 has its lower end hinged to the upper end of the first drive rod 4, and its other end hinged to the mounting plate 1. The second drive rod 5 is also inclined, but the inclination direction is opposite to that of the first drive rod 4.

[0043] Power source 6: Used to drive the first drive rod 4 to swing. Power source 6 can be a hydraulic cylinder or a pneumatic cylinder; in this embodiment, a hydraulic cylinder is used. The hydraulic cylinder is hinged to the lower part of the first drive rod 4.

[0044] The first drive rod 4, the second drive rod 5, and the power source 6 are each provided in two sets, located on both sides of the mounting plate 1 respectively. Through bidirectional synchronous drive, the mounting plate 1 is subjected to balanced force, eliminating tilting errors that may be caused by unilateral drive.

[0045] The first drive rod 4 is tilted, and when it swings to push the mounting plate 1, it can quickly amplify the swing angle of the power source 6 in the initial stage, causing the mounting plate 1 to produce a large stroke displacement. When approaching the target position, the increased tilt angle causes the lateral displacement rate to slow down, thus achieving "soft landing" precise positioning. In the traditional direct drive scheme, the displacement of the mounting plate 1 is linearly related to the output of the power source 6. However, in this scheme, the power source 6 only needs to control the swing angle. As the swing angle increases, the lateral displacement corresponding to a unit angle change decreases, thus improving the tolerance of the power source 6's repeatability positioning accuracy.

[0046] The tilt direction of the second drive rod 5 is opposite to that of the first drive rod 4. When the mounting plate 1 moves forward to the stop position, the tilt angle between the second drive rod 5 and the mounting plate 1 is 40°~50°, and in this embodiment, the tilt angle is 45°. At this time, the lateral component of the force of the second drive rod 5 is close to the vertical component, which reduces the thrust applied to the mounting plate 1 during the pushing process, further achieving "soft landing" precise positioning. This provides more options when selecting the power source 6, and it is not necessary to choose a power source 6 with precise thrust control.

[0047] Reference Figure 3 To facilitate adjustment of the stroke of the mounting plate 1, the second drive rod 5 employs a threaded adjustment rod with adjustable length. Furthermore, by adjusting the length of the second drive rod 5, its tilt angle can also be adjusted.

[0048] Mounting plate 1 has baffles 7 fixedly connected to both sides, and the frame 3 has limit switches 8 fixedly connected to the positions corresponding to the baffles 7. When mounting plate 1 moves forward until the limit switch 8 contacts the baffle 7, the power source 6 stops driving the first drive rod 4 to deflect. The hard contact between the mechanical baffle 7 and the limit switch 8 triggers the stop, improving reliability and avoiding malfunctions caused by electronic signal interference. At the same time, the position of the baffle 7 is adjustable to adapt to different travel requirements.

[0049] To further enhance safety, the frame 3 is threadedly connected to a screw 9, which is parallel to the limit switch 8 and corresponds to the position of the baffle 7. The screw 9 serves as the physical end point of the travel; when the limit switch 8 fails, it protects the battery and effectively mitigates the problem of crushing.

[0050] The implementation principle of this application embodiment is as follows: the hydraulic rod pushes the first drive rod 4 to swing, and the tilt angle of the first drive rod 4 increases, thereby pushing the mounting plate 1. In the initial stage, the swing angle of the power source 6 is rapidly amplified, causing the mounting plate 1 to produce a large stroke displacement, allowing the mounting plate 1 to approach the battery more quickly; when approaching the battery position, the increased tilt angle causes the lateral displacement rate to slow down, achieving a "soft landing" type of precise positioning. In the traditional direct drive scheme, the displacement of the mounting plate 1 is linearly related to the output of the power source 6, while in this scheme, the power source 6 only needs to control the swing angle. As the swing angle increases, the lateral displacement per unit angle decreases, improving the tolerance of the repeatability of the power source 6. In addition, this scheme uses a double tilting drive rod linkage mechanism composed of the first drive rod 4 and the second drive rod 5 to replace the traditional cylinder / hydraulic cylinder direct drive, realizing the mechanical amplification and precise control of the horizontal displacement.

[0051] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
