Technical Field
[0001] The present application relates to the technical field of ball linear guide rails, and in particular to a guide rail structure capable of preventing battery core self-discharge. Background Art
[0002] The ball linear guide is a high-precision, high-efficiency linear motion component, widely used in CNC machine tools, robots, automation equipment and other fields; when assembling lithium batteries, the ball linear guide needs to be used in the vertical direction. The slider slides on the guide rail, and the steel balls between the slider and the guide rail are easy to fall off from the slider. The fallen steel balls are easy to fall into the battery cells below. If they are not discovered in time, it is easy to cause abnormal self-discharge of the battery cells, which poses a safety hazard, so it needs to be improved. Utility Model Content
[0003] In order to prevent the steel balls from falling out of the slider, causing abnormal self-discharge of the battery cells, and to improve production safety, the present application provides a guide rail structure that can prevent self-discharge of the battery cells.
[0004] The present application provides a guide rail structure with a function of preventing battery core self-discharge, which adopts the following technical solution:
[0005] A guide rail structure with the function of preventing a battery core from self-discharging comprises a vertically arranged guide rail body, a slider is slidably connected to the guide rail body, a dust collecting box is arranged at the bottom end of the guide rail body, and a receiving interface for steel balls to enter is opened on the top wall of the dust collecting box.
[0006] By adopting the above technical solution, the steel balls that fall off the slider will be received and enter the dust collecting box. The dust collecting box serves to isolate the battery cells from the steel balls, preventing the steel balls from falling into the battery cells, causing abnormal self-discharge of the battery cells and causing safety hazards, thereby improving the safety of the guide rail body during use.
[0007] Optionally, it also includes a control module, which is electrically connected to the guide rail body, and the bottom wall of the dust collecting box is provided with a detection module for detecting foreign matter in the box. The detection module is communicatively connected with the control module, and the control module controls the opening and closing of the guide rail body based on the detection data of the detection module.
[0008] By adopting the above technical solution, when foreign objects such as steel balls enter the dust collecting box, they will be detected by the detection module of the dust collecting box, and then the detection data will be sent to the control module. The control module will cut off the power to the guide rail body and shut down the guide rail body to prepare for maintenance by the staff, thereby further improving the safety of the guide rail body during operation.
[0009] Optionally, a magnetic attraction module is provided on the inner wall of the dust collecting box, and the magnetic attraction module is magnetically attracted to the steel balls after being powered on.
[0010] By adopting the above technical solution, after the magnetic suction module is powered on, electromagnetism will be generated to adsorb the steel balls to prevent the steel balls from colliding with the bottom wall of the dust collecting box and rebounding after falling into the dust collecting box, causing the steel balls to bounce out of the dust collecting box and be inconvenient to be recovered, thereby improving the practicality of the dust collecting box.
[0011] Optionally, a slope is provided on the bottom wall of the dust collecting box, and a receiving box for steel balls to enter is provided at one end of the slope.
[0012] By adopting the above technical solution, when the magnetic module is powered off, the steel balls are no longer adsorbed on the inner wall of the dust collecting box. As a result, the steel balls can slide along the slope and enter the storage box for centralized storage, making it convenient for staff to remove foreign objects such as steel balls in the dust collecting box.
[0013] Optionally, the bottom wall of the dust receiving box is provided with a pick-up and release slot for the accommodating box to extend out of the dust receiving box, and a pick-up and release cylinder is arranged in the dust receiving box, the pick-up and release cylinder is arranged vertically, and the piston rod of the pick-up and release cylinder is connected to the accommodating box.
[0014] By adopting the above technical solution, the receiving box can be moved along the direction of the receiving slot by starting the pick-up and release cylinder, so that the staff can take out the steel balls in the receiving box from below, thereby improving the convenience of taking out foreign objects such as steel balls in the docking dust box.
[0015] Optionally, the dust collecting box is externally provided with an insulating layer.
[0016] By adopting the above technical solution, providing an insulating layer can prevent workers from accidentally touching the dust box and causing electric shock when the magnetic attraction module is powered on, thereby improving safety during the work process.
[0017] Optionally, two layers of buffer nets are arranged in the dust collecting box, the two buffer nets are distributed up and down, and the mesh holes on the two buffer nets are staggered.
[0018] By adopting the above technical solution, when the slider is located at the end of the guide rail body that is far away from the dust collecting box, if the steel ball falls off at this moment, the falling height is relatively high. After the steel ball falls into the dust collecting box, it is easy to cause damage to itself and the dust collecting box, affecting the normal use of the steel ball and the dust collecting box. The buffer net is set to receive and buffer the fallen steel balls. The staggered mesh holes of the two layers of the buffer net can effectively prevent the steel balls from passing through the mesh holes directly, thereby having the effect of slowing down the steel balls.
[0019] Optionally, an alarm module is provided on the outer wall of the dust collecting box, and the alarm module is communicatively connected with the control module.
[0020] By adopting the above technical solution, an alarm module is set up, which can receive a signal from the control module when the detection module detects the presence of foreign objects in the dust box, and then issue an alarm to remind the staff to clean up the foreign objects and repair the guide rail body, thereby saving downtime and waiting time and improving work efficiency.
[0021] In summary, the present application includes at least one of the following beneficial technical effects:
[0022] 1. The steel balls that fall off the slider will enter the dust box after being received. The dust box isolates the battery cells from the steel balls, preventing the steel balls from falling into the battery cells, causing abnormal self-discharge of the battery cells and causing potential safety hazards, thereby improving the safety of the guide rail body during use;
[0023] 2. After the magnetic module is powered on, it will generate electromagnetism to absorb the steel balls to prevent the steel balls from falling into the dust box and colliding with the bottom wall of the dust box and rebounding, causing the steel balls to pop out of the dust box and be inconvenient to recover, thereby improving the practicality of the dust box.

[0028] The following is combined with Figure 1-3 This application is described in further detail.
[0029] The present application embodiment discloses a guide rail structure that can prevent the self-discharge of the battery core. Figure 1 , Figure 2 and Figure 3, including a vertically arranged guide rail body 1, on which a slider 11 is slidably connected. In this embodiment, the guide rail body 1 and the slider 11 are combined to form a ball linear guide, and a steel ball is arranged in the slider 11 for sliding along the guide rail body 1; it also includes a control module 3, which adopts a PLC controller. The control module 3 is electrically connected to the guide rail body 1, and the opening and closing of the guide rail body 1 can be controlled by the control module 3.
[0030] Reference Figure 1 and Figure 2 A dust collecting box 2 is provided at the bottom end of the guide rail body 1, and a receiving interface 21 for steel balls to enter is opened on the top wall of the dust collecting box 2. Two layers of buffer nets 6 are provided in the dust collecting box 2. The two layers of buffer nets 6 are distributed up and down, and the meshes of the two layers of buffer nets 6 are staggered. The size of the mesh is larger than the diameter of the steel balls. When the steel balls fall from a higher place, the staggered buffer nets 6 can prevent the steel balls from falling directly into the bottom wall of the dust collecting box 2, causing damage to the bottom wall of the dust collecting box 2 or the steel balls, thereby achieving a deceleration and buffering effect; in this embodiment, the buffer net 6 is made of elastic material and has elasticity to prevent the steel balls from being unable to pass through the meshes.
[0031] Reference Figure 1 and Figure 2 A slope 22 is provided at the bottom of the dust collecting box 2, and the whole is funnel-shaped. A receiving box 23 is provided at the lower end of the slope 22 for the steel balls to roll in along the slope 22, so as to be taken out in a centralized manner; the dust collecting box 2 is provided with a receiving box 23, and a bottom wall thereof is provided with a taking-in and putting-out slot 24, so that the receiving box 23 can extend out of the dust collecting box 2; a taking-in and putting cylinder 25 is provided in the dust collecting box 2, and the taking-in and putting cylinder 25 is provided in the dust collecting box 2, and the taking-in and putting cylinder 25 is provided in the vertical direction, and a piston rod of the taking-in and putting cylinder 25 is connected to the receiving box 23, so as to drive the receiving box 23 to extend out of the taking-in and putting slot 24, so as to reduce the difficulty for the staff to take out foreign objects such as steel balls.
[0032] Reference Figure 1 , Figure 2 and Figure 3 A detection module 4 is provided at the bottom of the dust collecting box 2 to detect whether there are foreign objects in the dust collecting box 2. The detection module 4 is communicated with the control module 3. In this embodiment, the detection module 4 adopts a pressure sensor to detect the pressure on the bottom of the dust collecting box 2 in real time. If the steel ball falls off and falls into the dust collecting box 2, it will collide with the bottom wall of the dust collecting box 2, thereby generating a pressure difference. After detecting the pressure difference, the detection module 4 will transmit the detection data to the control module 3.

The alarm module adopts an audible and visual alarm to sound an alarm when the guide rail body 1 is shut down, so as to promptly remind the staff to inspect the guide rail body 1.
[0033] Reference Figure 1 , Figure 2 and Figure 3 A magnetic module 5 is also provided in the dust collecting box 2. In this embodiment, the magnetic module is an electromagnet buried in the bottom wall of the dust collecting box 2. After the magnetic module 5 is energized, it will be magnetically attracted to the steel balls entering the dust collecting box 2, thereby preventing the steel balls from colliding with the bottom wall of the dust collecting box 2 and rebounding from the dust collecting box 2 after entering the dust collecting box 2, making it inconvenient to recover; the outside of the dust collecting box 2 is wrapped with an insulating layer 26, and the insulating layer 26 is made of rubber material to prevent the staff from accidentally touching the dust collecting box 2 and getting an electric shock, thereby further improving safety.
