Description

Technical Field

[0001] This utility model relates to the field of spot welding equipment technology, specifically a spot welding device for battery processing. Background Technology

[0002] Utility model patent CN222492838U discloses a positioning platform for lithium battery spot welding. The platform includes a base, a platform surface fixedly mounted on one end of the base's outer surface, and grooves on both sides of the platform surface. A stop block is fixedly mounted on one end of the platform surface, and mounting slide rods are disposed within the grooves on both sides of the platform surface. A pushing mechanism is provided between the base and the platform surface to control the movement of the mounting slide rods. In this positioning platform for lithium battery spot welding, the lithium battery is placed on the platform surface. Then, a first cylinder is activated, causing it to retract and rotate a push rod back to its original position. A spring then pushes a bolt, causing a second fixing block to move. The movement of the second fixing block retracts the mounting slide rods, clamping the lithium battery. Simultaneously, the retraction of the second cylinder moves a sliding push rod, which, along with the stop block, positions the lithium battery and allows it to automatically align itself.

[0003] However, the device has some shortcomings in use. During the welding process, the welding head of the welding machine is not easy to control and does not make close contact with the battery surface. At the same time, the temperature at the welding point is high and the cooling is not efficient enough. Utility Model Content

[0004] The purpose of this invention is to provide a spot welding device for battery processing, which solves the problems of the welding head of the welding machine being difficult to control and making close contact with the battery surface during the welding process, and the high temperature at the welding point and inefficient cooling.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spot welding device for battery processing, comprising a base, a clamping plate slidably connected to the upper end of the base, a connecting plate slidably connected to the base, the connecting plate and the clamping plate being fixedly connected, a motor being fixedly installed at the left end of the base, the motor's rotating shaft passing through the base and rotatably connected to the base, a bidirectional screw being fixedly connected to the end of the motor's rotating shaft, the bidirectional screw being threadedly connected to the connecting plate, the bidirectional screw being rotatably connected to the base, a bracket being fixedly connected to the upper end of the base, an adjustment mechanism being provided on the bracket, an electric guide rail being provided on the adjustment mechanism, a cooling mechanism being provided on the electric guide rail, and a welding machine being provided on the cooling mechanism.

[0006] Preferably, the adjusting mechanism includes a motor. The motor is fixedly mounted on the upper end of the bracket. The output end of the motor passes through the bracket and is rotatably connected to it. A square rod is fixedly connected to the lower end of the motor's output end. A slide tube is slidably connected to the outer side of the square rod. A turntable is mounted on the outer side of the slide tube via a bearing. A cylinder is fixedly mounted on the upper end of the bracket. The cylinder rod passes through the bracket and is slidably connected to it. A sliding pin is fixedly connected to the surface of the cylinder rod. The sliding pin is fixedly connected to the turntable. A sliding sleeve is slidably connected to the outer side of the slide tube. The sliding sleeve is fixedly connected to an electric guide rail. A spring is provided inside the sliding sleeve. One end of the spring contacts the slide tube, and the other end contacts the electric guide rail. By elastically compressing the electric guide rail with the spring, the electric guide rail is elastically compressed, thereby ensuring elastic contact between the welding head of the welding machine and the battery. This avoids excessive or insufficient compression force, which could affect the welding quality of the battery.

[0007] Preferably, a guide pin is fixedly connected to the outer side of the slide tube, and the guide pin is slidably connected to the slide sleeve. By providing the guide pin, relative rotation between the slide tube and the slide sleeve is prevented.

The mounting plate is located at the lower end of the electric guide rail, and a transparent cylinder is fixedly connected to the lower end of the mounting plate. A conical shroud is slidably connected to the outer side of the transparent cylinder, and a retaining ring is rotatably connected to the outer side of the transparent cylinder. A compression spring is located on the outer side of the transparent cylinder. An air pump is fixedly mounted at the rear end of the support, and the air pump's inlet pipe passes through the support and is slidably connected to it. The air pump's inlet pipe is slidably connected to an annular groove on the transparent cylinder. The compression spring acts on the conical shroud, causing the protrusion on the conical shroud to contact the battery. Cold air is then introduced into the transparent cylinder by the air pump, thereby cooling the weld joint and rapidly cooling the welded joint.

[0009] Preferably, a guide block is fixedly connected inside the cone-shaped cover, and the guide block is slidably connected to the transparent cylinder. By setting the guide block, relative rotation between the cone-shaped cover and the transparent cylinder is prevented.

[0010] Preferably, one end of the compression spring is fixedly connected to the cone cover, and the other end of the compression spring is fixedly connected to the retaining ring. By setting the compression spring, the cone cover is elastically compressed downwards.

[0011] Preferably, a baffle is fixedly connected to the outside of the air inlet pipe of the air pump, and the baffle is rotatably connected to the transparent cylinder. By setting the baffle, the annular groove on the transparent cylinder is sealed.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a spring to elastically compress the electric guide rail, thereby causing the electric guide rail to be elastically compressed, which in turn allows the welding head of the welding machine to make elastic contact with the battery, avoiding excessive or insufficient compression force that could affect the welding quality of the battery.

[0014] 2. This utility model uses a compression spring to act on the cone cover, thereby making the protrusion on the cone cover contact with the battery, and uses an air pump to introduce cold air into the transparent cylinder, thereby blowing and cooling the solder joint, thus making the solder joint cool down quickly after welding.

The output end of the motor 71 passes through the bracket 6 and is rotatably connected to it. A square rod 72 is fixedly connected to the lower end of the output end of the motor 71. A slide tube 73 is slidably connected to the outer side of the square rod 72. A turntable 74 is mounted on the outer side of the slide tube 73 via a bearing. A cylinder 75 is fixedly mounted on the upper end of the bracket 6. The cylinder rod of the cylinder 75 passes through the bracket 6 and is slidably connected to it. A sliding pin 76 is fixedly connected to the surface of the cylinder rod of the cylinder 75. The sliding pin 76 is fixedly connected to the turntable 74. A sliding pin 76 is slidably connected to the outer side of the slide tube 73. The sleeve 77 and the sliding sleeve 77 are fixedly connected to the electric guide rail 8. The outer side of the sliding tube 73 is fixedly connected to the guide pin 78, which is slidably connected to the sliding sleeve 77. By setting the guide pin 78, the relative rotation of the sliding tube 73 and the sliding sleeve 77 is prevented. The sliding sleeve 77 is equipped with a spring 79. One end of the spring 79 contacts the sliding tube 73, and the other end of the spring 79 contacts the electric guide rail 8. The spring 79 elastically compresses the electric guide rail 8, thereby causing the electric guide rail 8 to be elastically compressed, which in turn causes the welding head of the welding machine 10 to elastically contact the battery, avoiding excessive or insufficient compression force, which would affect the welding quality of the battery.

[0023] Please see Figures 1-4The cooling mechanism 9 includes a mounting plate 91, which is fixedly mounted to the welding machine 10. The lower end of the electric guide rail 8 is provided with the mounting plate 91, and a transparent cylinder 92 is fixedly connected to the lower end of the mounting plate 91. A conical shroud 93 is slidably connected to the outer side of the transparent cylinder 92. A guide block 94 is fixedly connected inside the conical shroud 93, and the guide block 94 is slidably connected to the transparent cylinder 92. By setting the guide block 94, relative rotation between the conical shroud 93 and the transparent cylinder 92 is prevented. A retaining ring 95 is rotatably connected to the outer side of the transparent cylinder 92, and a compression spring 96 is provided on the outer side of the transparent cylinder 92. One end of the compression spring 96 is fixedly connected to the conical shroud 93, and the other end of the compression spring 96 is fixedly connected to the retaining ring 95. A compression spring 96 causes the cone cover 93 to be elastically pressed down. An air pump 97 is fixedly installed at the rear end of the bracket 6.

By setting the retaining sleeve 98, the annular groove on the transparent cylinder 92 is closed. The compression spring 96 acts on the cone cover 93, thereby causing the protrusion on the cone cover 93 to contact the battery. Cold air is introduced into the transparent cylinder 92 through the air pump 97, thereby blowing air to cool the solder joint, thus making the solder joint cool down quickly after welding.

[0024] The specific implementation process of this utility model is as follows: In use, the battery is placed on the base 1, the motor 4 is started, the motor 4 drives the bidirectional screw 5 to rotate, the bidirectional screw 5 rotates and the connecting plate 3 makes a threaded movement, thereby causing the connecting plate 3 to drive the clamping plate 2 to move and contact the battery, clamping and limiting the battery. Then, the motor 4 is started to adjust the position of the electric guide rail 8, and then the cylinder 75 is started. The cylinder 75 drives the cylinder rod to extend, the cylinder rod drives the sliding pin 76 to move, the sliding pin 76 drives the turntable 74 to move, the turntable 74 drives the sliding tube 73 to move, thereby causing the sliding tube 73 to move and compress the spring 79, causing the spring 79 to drive the electric guide rail 8 downward. The movement causes the mounting plate 91 to move downwards, which in turn causes the welding machine 10 to move downwards, allowing the welding head of the welding machine 10 to contact and weld with the battery. The electric guide rail 8 is elastically compressed by the spring 79, which in turn causes the welding head of the welding machine 10 to elastically contact the battery, avoiding excessive or insufficient compression force that could affect the welding quality of the battery. During this process, the compression spring 96 acts on the cone cover 93, causing the protrusion on the cone cover 93 to contact the battery. Cold air is introduced into the transparent cylinder 92 by the air pump 97, which blows air to cool the weld point, thus allowing the weld point to cool down quickly after welding.
