Description

Technical Field

[0001] This utility model belongs to the field of lead-acid battery production and processing technology, specifically relating to a tooling for grinding and oiling battery terminals. Background Technology

[0002] In the battery production process, in order to ensure the contact effect of the battery terminals and the appearance of the battery, it is necessary to polish the surface of the battery terminals, remove the surface oxide layer, and apply anti-oxidation oil to the surface of the terminals.

[0003] The existing solution involves manually grinding and lubricating the battery terminals, or using two separate machines: a battery terminal grinding machine and a battery terminal lubricating machine. This solution has the following problems:

[0004] Firstly, manual grinding and oiling of battery terminals results in low efficiency and high labor intensity for workers.

[0005] Secondly, if two devices, a battery terminal grinder and a battery terminal oiler, are used for grinding and oiling, the efficiency can be effectively improved, but the two devices occupy a large area and cannot be arranged in a small space.

[0006] The battery terminal lubrication device disclosed in Chinese patent CN202322991707.0 can achieve the process of uniformly applying oil to the battery terminals, but it still requires a battery terminal grinding equipment for the grinding process, which is inefficient.

[0007] Therefore, how to provide a tooling for grinding and oiling battery terminals is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0008] In view of this, the present invention provides a tooling for grinding and oiling battery terminals, which can perform surface grinding and anti-oxidation oil coating on battery terminals without the need for two sets of equipment. This product is highly integrated and can complete the grinding and oiling processes at the same station.

[0009] To achieve the above objectives, this utility model adopts the following technical solution: a tooling for grinding and oiling battery terminals, comprising:

[0010] A drive motor, which can be fixedly connected to an external lifting device;

[0011] Mounting base, the mounting base being fixedly connected to the output shaft of the drive motor;

[0012] A pneumatic gripper, the pneumatic gripper being fixed on the mounting base, and a grinding brush being detachably connected to the gripper body;

[0013] An oiling valve is fixed below the mounting base and has a clearance distance from the grinding brush on the claw body. The bottom center of the oiling valve has a clearance hole for the battery terminal to enter. The valve body of the oiling valve has multiple valve core holes. One end of each valve core hole is connected to the clearance hole. A valve core is axially slidably connected inside the valve core hole. The end of the valve core near the clearance hole is the oiling end. An oil passage hole is opened on the valve body to connect to the side wall of the valve core hole. The battery terminal supports the valve core and causes the valve core to move axially. The axial movement of the valve core controls the connection between the oil passage hole and the clearance hole. The anti-oxidation oil in the oil passage hole wets the oiling end and completes the oiling process of the battery terminal.

[0014] The beneficial effects of this utility model are as follows: The drive motor is the core driving component for grinding with the grinding brush and applying oil with the oiling valve. The grinding brush is detachably connected to the pneumatic gripper. When grinding the battery terminals, the grinding brush forms a closed state, and the grinding process of the battery terminals is achieved by the rotation of the grinding brush. After grinding, no other equipment is needed. Simply move the fixture down, and after the oiling valve contacts the battery terminals, the anti-oxidation oil can be applied to the battery terminals by the forward and reverse rotation of the drive motor output shaft. This product has an integrated design, which is more efficient than the traditional use of two devices (grinding machine and oiling machine) and effectively solves the problem of large footprint when using two devices, saving layout space.

[0015] Preferably, the mounting base, pneumatic gripper, and oiling valve are all located at the rotation center of the output shaft of the drive motor.

[0016] The resulting technical effect is that the mounting base, pneumatic gripper, and oiling valve are all located at the rotation center of the output shaft of the drive motor, ensuring the stability of the pneumatic gripper and oiling valve during operation and avoiding large-scale shaking that would affect the grinding and oiling effect.

[0017] Preferably, the polishing brush has an arc-shaped polishing surface that matches the outer wall of the battery terminal, and the multiple polishing brushes on the pneumatic gripper hug the outer wall of the battery terminal when polishing the battery terminal.

[0018] The resulting technical effect is that, in practice, the polishing brush is connected to the inner end of the claw body with screws, and the arc-shaped polishing surface on the polishing brush is adapted to the outer wall surface of the battery terminal, thereby realizing the polishing process of the battery terminal.

[0019] Preferably, the oil passage hole on the oiling valve is connected to an external oil pipe, and a return spring is connected to the other end of the valve core hole. The valve core is connected to the return spring and causes the valve core to tend to spring outward.

[0020] The resulting technical effect is that the return spring on the valve core hole can maintain the valve core's tendency to spring outwards. When not lubricated, the outward springing of the valve core can block the outflow of anti-oxidation oil.

[0021] Preferably, the valve core hole is a wedge-shaped hole, with the smaller diameter end of the valve core hole close to the clearance hole. The valve core is a wedge-shaped structure adapted to the valve core hole. The end face of the valve core corresponding to the oiling end is provided with a conical guide arc surface and a semi-circular oiling surface. A sponge layer is provided on the semi-circular oiling surface. The conical guide arc surface is located at the lower part of the semi-circular oiling surface. Multiple oil guide grooves are opened on the top surface of the valve core. One end of the oil guide groove has a tight contact surface with the oiling end. The tight contact surface is in close contact with the side wall of the valve core hole and controls the communication relationship between the oil passage hole and the clearance hole.

[0022] The resulting technical effect is that the wedge-shaped hole ensures an overflow gap when the valve core moves axially, allowing the anti-oxidation oil to wet the sponge layer and complete the oiling process for the battery terminals. Of course, before the battery terminals enter the clearance hole, the valve core is in an outward-springing state. In this state, the sealing surface is in close contact with the hole wall of the valve core and blocks the flow of anti-oxidation oil. The purpose of the tapered guide arc surface is that when the battery terminals enter the clearance hole, the outer wall of the battery terminals can open the valve core, causing it to move axially, which facilitates the subsequent flow of anti-oxidation oil.

[0023] Preferably, the clearance hole is an inverted conical hole, and the taper of the conical guide arc surface is greater than the taper of the clearance hole.

[0024] The resulting technical effect is that the tapered guide surface has a large taper, which enables the battery terminals to open the valve core, and it is applicable regardless of whether the battery terminals are cylindrical or tapered.

[0025] Preferably, the bottom of the oil guide groove is horizontally arranged, and one end of the bottom of the oil guide groove extends to the contact surface.

[0026] The resulting technical effect is that, as can be understood, the oil guide groove is water-sealed, with one end of its bottom extending to the contact surface, facilitating the sealing and flow of the anti-oxidation oil. This utility model integrates both grinding and oiling functions, replacing manual operation and eliminating the need for two separate machines for terminal grinding and oiling, thus reducing the labor intensity of employees and improving work efficiency.

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] See appendix to this utility model Figures 1 to 6 According to an embodiment of the present invention, a tooling for grinding and oiling battery terminals includes:

[0036] Drive motor 1, which can be fixedly connected to external lifting device 6;

[0037] Mounting base 2 is fixedly connected to the output shaft of drive motor 1;

[0038] Pneumatic gripper 3 is fixed on mounting base 2. A polishing brush 4 is detachably connected to the gripper body of pneumatic gripper 3. The polishing brush is used to polish the battery terminals.

[0039] The oiling valve 5 is fixed below the mounting base 2 and has a clearance distance from the grinding brush 4 on the claw body. It should be noted that when the grinding brush is grinding the battery terminal, the oiling valve will not affect it. The bottom center of the oiling valve 5 has a clearance hole 51 for the battery terminal to enter. The valve body of the oiling valve 5 has two valve core holes 52 horizontally arranged symmetrically. One end of the valve core hole 52 is connected to the clearance hole 51. A valve core 54 is axially slidably connected inside the valve core hole 52. The end of the valve core 54 near the clearance hole 51 is the oiling end. The valve body has an oil passage hole 53 that connects to the side wall of the valve core hole 52. The battery terminal supports the valve core 54 and causes the valve core to move axially. The axial movement of the valve core 54 controls the connection between the oil passage hole 53 and the clearance hole 51. The anti-oxidation oil in the oil passage hole 53 wets the oiling end and completes the oiling process of the battery terminal.

[0040] In other embodiments, the mounting base 2, the pneumatic gripper 3, and the oiling valve 5 are all located at the rotation center of the output shaft of the drive motor 1. This ensures that there will be no significant shaking during the grinding or oiling process, thus guaranteeing that the grinding or oiling will proceed smoothly.

[0041] In some other embodiments, the polishing brush 4 has an arc-shaped polishing surface that matches the outer wall of the battery terminal. The two polishing brushes on the pneumatic gripper 3 hug the outer wall of the battery terminal when polishing the battery terminal, thereby achieving the polishing of the battery terminal.

[0042] In some other specific embodiments, the oil passage hole 53 on the oiling valve 5 is connected to an external oil pipe, and the other end of the valve core hole 52 is connected to a return spring 55. The valve core 54 is connected to the return spring 55 and causes the valve core 54 to tend to spring outward.

[0043] In other embodiments, the valve core hole 52 is a wedge-shaped hole, with the small-diameter end of the valve core hole 52 close to the avoidance hole 51. The valve core 54 is a wedge-shaped structure adapted to the valve core hole 52. The end face of the valve core 54 corresponding to the oiling end is provided with a conical guide arc surface 57 and a semi-circular oiling surface 58. A sponge layer is provided on the semi-circular oiling surface 58. The conical guide arc surface 57 is located at the lower part of the semi-circular oiling surface 58. Multiple oil guide grooves 56 are opened on the top surface of the valve core 54. One end of the oil guide groove 56 is in close contact with the oiling end with a tight contact surface 59. The tight contact surface 59 is in close contact with the side wall of the valve core hole 52 and controls the communication relationship between the oil passage hole 53 and the avoidance hole 51.

[0044] In some other specific embodiments, the clearance hole 51 is an inverted conical hole, and the taper of the conical guide arc surface 57 is greater than the taper of the clearance hole 51. This ensures that when the battery terminal enters the clearance hole, the valve core can be opened, thereby achieving the effect of preventing the flow of oxidation oil.

[0045] In other embodiments, the bottom of the oil guide groove 56 is horizontally set, and one end of the bottom of the oil guide groove 56 extends to the sealing surface 59. The sealing surface actually serves to seal the oil passage hole and the avoidance hole. When the valve core retracts, the sealing surface disengages from the inner wall of the valve core hole, and the anti-oxidation oil in the oil passage hole wets the oiling end through the gap, thereby realizing the oiling of the battery terminal.

[0046] The sanding and oiling process is as follows:

[0047] Step 1: Move the battery to be processed to the bottom of the fixture, which is controlled by an external lifting device and lowered to the grinding station height;

[0048] Step 2: The pneumatic gripper controls the two grippers to merge, and the polishing brush on the gripper contacts the outer wall of the battery terminal. The drive motor is started, and the output shaft of the drive motor moves in 180° forward and reverse rotation to realize the working process of polishing the battery terminal with the polishing brush.

[0049] Step 3: After the preset polishing time, the drive motor stops working, the pneumatic gripper opens, and the external lifting device controls the fixture to continue to descend to the oiling station height. At this time, the battery terminal extends into the clearance hole, and the valve core in the clearance hole retracts under the support of the battery terminal. The oil passage hole connects with the clearance hole, and the anti-oxidation oil in the oil passage hole wets the oiling end. At this time, the output shaft of the drive motor rotates 180° in both directions to realize the oiling process of the oiling part on the battery terminal.

[0050] Step 4: After the preset oiling time, the drive motor stops working, the external lifting device controls the fixture to move upward, the valve core moves outward after detaching from the battery terminal and blocks the passage between the oil passage hole and the clearance hole, and the anti-oxidation oil in the oil passage hole stops flowing, thus completing the grinding and oiling process of the battery terminal.

[0051] This invention integrates two functions: grinding and oiling. It can be completed with a single set of equipment, saving costs while improving processing efficiency and making it easy to promote and use.

[0052] The apparatus and methods disclosed in the embodiments are described in a relatively simple manner since they correspond to the methods disclosed in the embodiments. For relevant details, please refer to the description in the method section.

[0053] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
