Description

Technical Field

[0001] The invention belongs to the technical field of lead-acid battery production and processing, and particularly relates to a tool and method for polishing and oiling battery terminals. Background Art

[0002] During the battery production process, in order to ensure the contact effect of the battery terminals and the appearance of the battery, the surface of the battery terminals needs to be polished, the surface oxide layer needs to be removed, and anti-oxidation oil needs to be applied to the terminal surface.

[0003] The existing solution is to manually grind and oil the battery terminals, or use a battery terminal grinder and a battery terminal oiler to perform this work. This solution has the following problems:

[0004] First, the battery terminals are manually polished and oiled, resulting in low polishing and oiling efficiency and high labor intensity;

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

[0006] The battery terminal lubrication device disclosed in Chinese patent CN202322991707.0 can realize the process of evenly greasing the battery terminals, but it still requires battery terminal grinding equipment to perform the grinding process, which is inefficient.

[0007] Therefore, how to provide a tool and method for polishing and oiling battery terminals is a problem that those skilled in the art need to solve urgently. Summary of the invention

[0008] In view of this, the present invention provides a tool and method for polishing and oiling battery terminals, which can perform surface polishing 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 two processes of polishing and oiling at the same workstation.

[0009] In order to achieve the above object, the present invention adopts the following technical solution: a tool for polishing and oiling battery terminals, comprising:

[0010] A driving motor, wherein the driving motor can be fixedly connected to an external lifting device;

[0011] A mounting seat, the mounting seat is fixedly connected to the output shaft of the driving motor;

[0012] A pneumatic clamp, wherein the pneumatic clamp is fixed on the mounting seat, and a grinding brush is detachably connected to the jaw body of the pneumatic clamp;

[0013] An oiling valve, wherein the oiling valve is fixed below the mounting seat and has an avoidance distance from the grinding brush on the claw body, a avoidance hole for the battery terminal to enter is provided in the middle of the bottom side of the oiling valve, a plurality of valve core holes are provided on the valve body of the oiling valve, one end of the valve core hole is connected to the avoidance hole, a valve core is axially slidably connected in the valve core hole, one end of the valve core close to the avoidance hole is an oiling end, an oil path hole connected to the side wall of the valve core hole is provided on the valve body, 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 relationship between the oil path hole and the avoidance hole, the anti-oxidation oil in the oil path hole wets the oiling end and completes the oiling process of the battery terminal.

[0014] The beneficial effects of the present invention are as follows: the driving motor is the core driving component for grinding with a grinding brush and oiling with an oiling valve; the grinding brush is detachably connected to the claw body of the pneumatic clamp; when grinding the battery terminal, the grinding brush forms an embracing state, and the grinding process of the battery terminal is realized by the rotation of the grinding brush; after the grinding is completed, no additional equipment is required, and only the tooling needs to be moved down; after the oiling valve is in contact with the battery terminal, the anti-oxidation oil can be applied to the battery terminal by the forward and reverse rotation process of the output shaft of the driving motor; the integrated design of this product is higher in work efficiency than the traditional use of two devices (grinding machine and oiling machine), and effectively solves the problem of a large footprint caused by the use of two devices, saving layout space.

[0015] Preferably, the mounting seat, the pneumatic clamping jaws, and the oiling valve are all located on the rotation center of the output shaft of the driving motor.

[0016] The resulting technical effect is that the mounting seat, pneumatic clamp and oiling valve are all located on the rotation center of the output shaft of the drive motor, ensuring the stability of the pneumatic clamp and oiling valve during operation and avoiding large shaking that affects the grinding and oiling effects.

[0017] Preferably, the grinding brush has an arc-shaped grinding surface that matches the outer wall surface of the battery terminal, and the multiple grinding brushes on the pneumatic clamp are clasped on the outer side wall of the battery terminal when grinding the battery terminal.

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

[0019] Preferably, the oil passage hole on the oil-coating valve is connected to an external oil pipe, the other end of the valve core hole is connected to a return spring, and the valve core is connected to the return spring and causes the valve core to have a tendency to bounce outwards.

[0020] The resulting technical effect is that the return spring on the valve core hole can keep the valve core from springing outwards, and when working without oil application, the outward springing of the valve core can block the outflow of the anti-oxidation oil.

[0021] Preferably, the valve core hole is a wedge-shaped hole, the small-diameter end of the valve core hole is close to the avoidance hole, the valve core is a wedge-shaped structure adapted to the valve core hole, and a conical guide arc surface and a semicircular oiling surface are provided on the end face of the valve core corresponding to the oiling end, a sponge layer is provided on the semicircular oiling surface, the conical guide arc surface is located at the lower part of the semicircular oiling surface, and a plurality of oil guide grooves are provided on the top surface of the valve core, a close contact surface is provided between one end of the oil guide groove and the oiling end, the close contact surface is in close contact with the side wall of the valve core hole and controls the connectivity between the oil path hole and the avoidance hole.

[0022] The resulting technical effect is: the setting of the wedge-shaped hole ensures that there is an overflow gap when the valve core moves axially, and the anti-oxidation oil wets the sponge layer to complete the oiling process of the battery terminal. Of course, before the battery terminal enters the avoidance hole, the valve core is in an outward elastic state. In this state, the sealing surface is in close contact with the hole wall of the valve core hole and blocks the flow of the anti-oxidation oil. The purpose of the conical guide arc surface is that when the battery terminal enters the avoidance hole, the outer wall of the battery terminal can support the valve core to make it move axially, which is convenient for the subsequent flow of the anti-oxidation oil.

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

[0024] The resulting technical effect is that the conical guide arc surface has a larger taper, so that the battery terminal can achieve the effect of opening the valve core, and it is applicable whether the battery terminal is cylindrical or conical.

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

[0026] The technical effect produced thereby is: it can be understood that the oil guide groove is opened by water, and one end of the groove bottom extends to the close contact surface, which is convenient for achieving the sealing and flow relationship of the anti-oxidation oil.

[0027] The present invention also discloses a method for polishing and oiling battery terminals, which uses the above-mentioned tooling and comprises the following steps:

[0028] Step 1: Move the battery to be processed under the tooling, which is controlled by an external lifting device and lowered to the height of the grinding station;

[0029] Step 2: The pneumatic gripper controls the two claws to merge, and the grinding brush on the claw contacts the outer wall of the battery terminal. The drive motor is started, and the output shaft of the drive motor moves 180 degrees forward and reverse, realizing the working process of the grinding brush grinding the battery terminal.

[0030] Step 3: On the basis of step 2, after the preset grinding time, the drive motor stops working, the pneumatic clamp opens, and the external lifting device controls the tooling to continue to descend to the oiling station height. At this time, the battery terminal extends into the avoidance hole, and the valve core in the avoidance hole retreats under the support of the battery terminal. The oil passage hole is connected with the avoidance 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 back and forth at 180 degrees to realize the oiling process of the battery terminal by the oiling part;

[0031] Step 4: Based on step 3, after the preset oiling time, the drive motor stops working, the external lifting device controls the tooling to move up, the valve core moves outward after detaching from the battery terminal and blocks the passage relationship between the oil passage hole and the avoidance hole, and the anti-oxidation oil in the oil passage hole stops flowing, thus completing the grinding and oiling process of the battery terminal.

[0032] The resulting technical effect is that the present invention integrates the two functions of polishing and oiling, replacing manual operation, and there is no need to use two devices for terminal polishing and oiling, which reduces the labor intensity of employees and improves work efficiency.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See the attached Figures 1 to 6 According to an embodiment of the present invention, a tool for polishing and oiling battery terminals comprises:

[0042] A driving motor 1, which can be fixedly connected to an external lifting device 6;

[0043] A mounting base 2, the mounting base 2 is fixedly connected to the output shaft of the driving motor 1;

[0044] A pneumatic clamp 3 is fixed on the mounting base 2, and a grinding brush 4 is detachably connected to the jaw body of the pneumatic clamp 3, and the grinding brush is used for grinding the battery terminal;

[0045] The oiling valve 5 is fixed below the mounting base 2 and has an avoidance distance from the grinding brush 4 on the claw body. It should be noted that when the grinding brush is embracing and grinding the battery terminal, the oiling valve will not affect it. A avoidance hole 51 for the battery terminal to enter is provided in the middle of the bottom side of the oiling valve 5. Two valve core holes 52 are horizontally provided on the valve body of the oiling valve 5. The two valve core holes are symmetrically arranged. One end of the valve core hole 52 is connected to the avoidance hole 51. A valve core 54 is axially slidably connected in the valve core hole 52. The end of the valve core 54 close to the avoidance hole 51 is the oiling end. An oil path hole 53 connected to the side wall of the valve core hole 52 is provided on the valve body. 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 relationship between the oil path hole 53 and the avoidance hole 51. The anti-oxidation oil in the oil path hole 53 wets the oiling end and completes the oiling process of the battery terminal.

[0046] In other embodiments, the mounting seat 2, the pneumatic clamp 3, and the oiling valve 5 are all located on the rotation center of the output shaft of the driving motor 1, so that no large shaking will occur during either the grinding or oiling process, thereby ensuring smooth grinding or oiling.

[0047] In some other embodiments, the grinding brush 4 has an arc-shaped grinding surface that matches the outer wall of the battery terminal. When grinding the battery terminal, the two grinding brushes on the pneumatic clamp 3 embrace the outer wall of the battery terminal, thereby achieving grinding of the battery terminal.

[0048] In some other specific embodiments, the oil passage hole 53 on the oil lubrication valve 5 is connected to an external oil pipe, the other end of the valve core hole 52 is connected to a return spring 55, and the valve core 54 is connected to the return spring 55 to cause the valve core 54 to have a tendency to bounce outward.

[0049] In other embodiments, the valve core hole 52 is a wedge-shaped hole, and the small-diameter end of the valve core hole 52 is close to the avoidance hole 51. The valve core 54 is a wedge-shaped structure adapted to the valve core hole 52. A conical guide arc surface 57 and a semicircular oiling surface 58 are provided on the end surface of the valve core 54 corresponding to the oiling end. A sponge layer is provided on the semicircular oiling surface 58. The conical guide arc surface 57 is located at the lower part of the semicircular oiling surface 58. A plurality of oil guide grooves 56 are provided on the top surface of the valve core 54. A sealing surface 59 is provided between one end of the oil guide groove 56 and the oiling end. The sealing surface 59 is in close contact with the side wall of the valve core hole 52 and controls the connection relationship between the oil path hole 53 and the avoidance hole 51.

[0050] In other specific embodiments, the avoidance hole 51 is an inverted tapered hole, and the taper of the tapered guide arc surface 57 is greater than the taper of the avoidance hole 51. This ensures that when the battery terminal enters the avoidance hole, the valve core can be opened, thereby achieving the flow effect of the anti-oxidation oil.

[0051] In other embodiments, the bottom of the oil guide groove 56 is arranged horizontally, 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 circuit hole and the avoidance hole. When the valve core retreats, the sealing surface is out of contact with the inner wall of the valve core hole, and the anti-oxidation oil in the oil circuit hole wets the oiling end through the gap, thereby realizing oiling of the battery terminal.

[0052] The present invention also discloses a method for polishing and oiling battery terminals, which uses the above-mentioned tooling and includes the following steps:

[0053] Step 1: Move the battery to be processed under the tooling, which is controlled by an external lifting device and lowered to the height of the grinding station;

[0054] Step 2: The pneumatic gripper controls the two claws to merge, and the grinding brush on the claw contacts the outer wall of the battery terminal. The drive motor is started, and the output shaft of the drive motor moves 180 degrees forward and reverse, realizing the working process of the grinding brush grinding the battery terminal.

[0055] Step 3: After the preset grinding time, the drive motor stops working, the pneumatic clamp opens, and the external lifting device controls the tooling to continue to descend to the oiling station height. At this time, the battery terminal extends into the avoidance hole, and the valve core in the avoidance hole retreats under the support of the battery terminal. The oil passage hole is connected with the avoidance 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 back and forth at 180 degrees to realize the oiling process of the battery terminal by the oiling part;

[0056] Step 4: After the preset oiling time, the drive motor stops working, the external lifting device controls the tooling to move up, the valve core moves outward after separating from the battery terminal and blocks the passage relationship between the oil passage hole and the avoidance hole, and the anti-oxidation oil in the oil passage hole stops flowing, thus completing the grinding and oiling process of the battery terminal.

[0057] The present invention integrates the two functions of polishing and oiling, which can be completed with one set of equipment, thus saving costs and improving processing efficiency, and is easy to promote and use.

[0058] As for the device and the method of use disclosed in the embodiment, since they correspond to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the description of the method part.

[0059] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be 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 will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
