Description

Technical Field

[0001] The utility model relates to the technical field of welding mechanisms, and particularly relates to a laser welding mechanism for a battery temperature switch. Background Art

[0002] A battery temperature switch is a safety device used to protect the battery from overheating damage. It is usually composed of a bimetallic temperature sensing element, which can act quickly when the battery temperature rises to a certain value, and protect the battery from damage by cutting off or connecting the circuit. This switch will automatically recover after the battery temperature drops to a safe level to ensure the normal operation of the battery. Battery temperature switches are widely used in various electronic devices, such as household appliance motors, electrical equipment, electric heating appliances, etc., to protect the battery pack from overheating or overcharging and improve the safety and reliability of the equipment. During the production process of the battery temperature switch, a laser welding mechanism is required to perform laser welding on the battery temperature switch.

[0003] The welding mechanisms of the prior art all require workers to manually place the welding die under the welding torch, and still need to manually take out the welding die after welding is completed. This is not only cumbersome and inefficient in operation, but also there are certain safety hazards in manually taking and placing the welding die. Content of the Utility Model

[0004] In order to solve the above problems, the utility model provides a laser welding mechanism for a battery temperature switch.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A laser welding mechanism for a battery temperature switch includes a base and a laser welding machine arranged on the side wall of the base. A chute is opened on the upper surface of the base. A pushing component for pushing the welding die under the laser welding machine is installed on the base. The pushing component includes a first motor fixed to the side wall of the base. The output shaft of the first motor penetrates through the side wall of the base and is rotatably connected. The pushing component further includes a pushing plate slidably connected to the inner wall of the chute and a first screw rod penetrating through the side wall of the pushing plate and threadedly connected thereto. One end of the first screw rod is rotatably connected to the inner wall of the chute, and the other end of the first screw rod is fixed to the end of the output shaft of the first motor;

[0006] A moving component for moving the welding mold is installed on the base. The moving component includes a mounting block fixed to the upper surface of the base and a second motor fixed to the side wall of the mounting block. A moving groove is formed in the side wall of the mounting block close to the pushing plate. The output shaft of the second motor penetrates the side wall of the mounting block and is rotatably connected. The moving component further includes a moving plate slidably connected to the inner wall of the moving groove and a second lead screw penetrating and threadedly connected to the side wall of the moving plate. One end of the second lead screw is rotatably connected to the inner wall of the moving groove, and the other end of the second lead screw is fixed to the end of the output shaft of the second motor. A controller electrically connected to the laser welding machine, the first motor, and the second motor is arranged on the side wall of the base. A positioning component for pressing the welding mold is installed on the base.

[0007] By adopting the above technical solution, when laser welding of the battery temperature switch is required, the staff places the welding mold on the conveyor belt and transports it to the base. The controller starts the first motor to drive the first screw to rotate. Since the first screw is threadedly connected to the pushing plate and the pushing plate is slidably connected to the inner wall of the sliding groove, the pushing plate moves along the axial direction of the first screw, pushes the welding mold under the laser welding machine, and presses the welding mold through the positioning component, so that the laser welding machine welds the battery temperature switch in the welding mold. After welding is completed, the controller starts the second motor to drive the second screw to rotate, so that the moving plate pushes the welding mold onto another conveyor belt, eliminating the dangerous operation of manually picking and placing the welding mold and improving the welding efficiency of the battery temperature switch.

[0008] Furthermore, the positioning component includes a mounting plate fixed to the upper surface of the base, a fixing plate fixed to the upper surface of the mounting plate, a linear motor arranged on the side wall of the fixing plate, and a positioning mold mounted on the linear motor. The linear motor is electrically connected to the controller.

[0009] By adopting the above technical solution, after the pushing component pushes the welding mold under the laser welding machine, the controller controls the linear motor to move the positioning mold downward and press against the welding mold, enhancing the stability of the welding mold and reducing the probability of the welding position shifting during laser welding.

[0010] Furthermore, a rubber sheet is fixed to the side wall of the mounting block close to the pushing plate.

[0011] By adopting the above technical solution, the rubber sheet is made of rubber material, and its material is elastic, reducing the vibration generated when the pushing plate pushes the welding mold to one side of the mounting block and reducing the wear between the mounting block and the welding mold.

[0012] Furthermore, a blocking plate is fixed to the upper surface of the base.

[0013] By adopting the above technical solution, the baffle plays a limiting role on the welding die, reducing the probability of the welding die falling when entering the base from the conveyor belt.

[0014] Furthermore, a collection assembly is installed on the base. The collection assembly includes a collection box fixed to the side wall of the base, an exhaust fan fixed to and communicating with the side wall of the collection box, a collection pipe fixed to and communicating with the upper surface of the collection box, and a collection hood fixed to and communicating with one end of the collection pipe away from the collection box. The collection hood is arranged on the upper surface of the mounting block, and the exhaust fan is electrically connected to the controller.

[0015] By adopting the above technical solution, when the exhaust fan is started, dust, fumes, etc. generated during the welding process are sucked into the collection box through the collection pipe and the collection hood, reducing the probability of dust, fumes, etc. polluting the working environment and even endangering the physical health of personnel.

[0016] Furthermore, plug-in blocks are fixed to the side walls on both sides of the base.

[0017] By adopting the above technical solution, the conveyor belts on both sides of the base are plugged into the plug-in blocks, connecting the conveyor belts to the base and reducing the probability of the conveyor belts shifting in position.

[0018] Furthermore, the cross-section of the plug-in block is in the shape of a dovetail.

[0019] By adopting the above technical solution, the dovetail-shaped plug-in block avoids the situation where the conveyor belt disengages from the base from the side, enhancing the stability of the connection between the conveyor belt and the base.

[0020] In summary, the present utility model has the following beneficial effects:

[0021] 1. In this application, when laser welding of the battery temperature switch is required, the staff places the welding die on the conveyor belt and transports it to the base. The controller starts the first motor to drive the first screw to rotate. Since the first screw is threadedly connected to the pushing plate and the pushing plate is slidably connected to the inner wall of the chute, the pushing plate moves along the axial direction of the first screw, pushing the welding die under the laser welding machine and pressing the welding die through the positioning assembly, so that the laser welding machine welds the battery temperature switch in the welding die. After the welding is completed, the controller starts the second motor to drive the second screw to rotate, and the moving plate pushes the welding die onto another conveyor belt, eliminating the dangerous operation of manually picking and placing the welding die and improving the welding efficiency of the battery temperature switch;

[0022] 2. In this application, after the welding die is pushed under the laser welding machine by the pushing assembly, the controller controls the linear motor to move the positioning die downward and press against the welding die, enhancing the stability of the welding die and reducing the probability of the welding position shifting during laser welding;

[0023] 3. In this application, the rubber sheet is made of rubber material, and its material is elastic, reducing the vibration generated when the pushing plate pushes the welding mold to one side of the mounting block, and reducing the wear between the mounting block and the welding mold.

The pushing plate 32 is a rectangular plate structure, and the pushing plate 32 is slidably connected to the inner wall of the sliding groove 11.

[0032] The moving component 4 is installed on the base 1 and is used to move the welding mold out. The moving component 4 includes a mounting block 41, a second motor 42, a moving plate 43, and a second lead screw 44. The mounting block 41 is a cuboid structure, and a moving groove 411 is formed on the side wall of the mounting block 41 close to the pushing plate 32. The second motor 42 is fixed on the side wall of the mounting block 41, and the output shaft of the second motor 42 penetrates through the side wall of the mounting block 41 and is rotatably connected. The moving plate 43 is a rectangular plate structure, and the moving plate 43 is slidably connected to the inner wall of the moving groove 411. The second lead screw 44 is a rod-shaped structure arranged horizontally. The second lead screw 44 penetrates through the side wall of the moving plate 43 and is threadedly connected.

[0033] The positioning component 6 is installed on the base 1 and is used to press the welding mold. The positioning component 6 includes a mounting plate 61, a fixing plate 62, a linear motor 63, and a positioning mold 64. The mounting plate 61 is a rectangular plate structure, and the mounting plate 61 is fixed on the upper surface of the base 1, and two mounting plates 61 are symmetrically arranged. The fixing plate 62 is a plate structure, and the fixing plate 62 is fixed on the upper surfaces of the two mounting plates 61. The linear motor 63 is a linear motor 63 commonly used in the prior art and applicable to this embodiment.

The positioning mold 64 is installed on the side wall of the linear motor 63, and the positioning mold 64 is located directly below the welding torch of the laser welding machine 2.

[0034] When laser welding the battery temperature switch is required, the staff place the welding die on the conveyor belt and transport it to the base 1. The controller 5 starts the first motor 31 to drive the first screw to rotate. Since the first screw is threadedly connected to the push plate 32 and the push plate 32 is slidably connected to the inner wall of the chute 11, the push plate 32 moves along the axial direction of the first screw, pushing the welding die under the laser welding machine 2. And the linear motor 63 is controlled by the controller 5 to move the positioning die 64 downward and press it against the welding die, enhancing the stability of the welding die and reducing the probability of the welding position shifting during laser welding. Then the laser welding machine 2 welds the battery temperature switch in the welding die. After welding is completed, the controller 5 starts the second motor 42 to drive the second screw to rotate, and the moving plate 43 pushes the welding die onto another conveyor belt, eliminating the dangerous operation of manually picking and placing the welding die and improving the welding efficiency of the battery temperature switch.

[0035] To reduce the wear between the mounting block 41 and the welding die, a rubber sheet 7 is fixed to the side wall of the mounting block 41 close to the push plate 32. The rubber sheet 7 is made of rubber material and has elastic texture, reducing the vibration generated when the push plate 32 pushes the welding die to one side of the mounting block 41, thereby reducing the wear between the mounting block 41 and the welding die.

[0036] To reduce the probability of the welding die falling when entering the base 1 from the conveyor belt, a baffle 8 is fixed on the upper surface of the base 1. The baffle 8 plays a role in limiting the welding die, thereby reducing the probability of the welding die falling when entering the base 1 from the conveyor belt.

[0037] To reduce the probability of dust, fumes, etc. polluting the working environment and even endangering the physical health of personnel, a collection component 9 is installed on the base 1. The collection component 9 includes a collection box 91, an exhaust fan 92, a collection pipe 93 and a collection hood 94. The collection box 91 is a cuboid box structure and is fixed on the side wall of the base 1. The exhaust fan 92 is a commonly used and applicable exhaust fan 92 in the prior art, and the exhaust fan 92 is fixed and communicated with the side wall of the collection box 91 and is electrically connected to the controller 5. The collection pipe 93 is a tubular structure and is fixed and communicated with the upper surface of the collection box 91. The collection hood 94 is fixed and communicated with the end of the collection pipe 93 away from the collection box 91, and the collection hood 94 is arranged on the upper surface of the mounting block 41. Starting the exhaust fan 92 sucks the dust, fumes, etc. generated during welding into the collection box 91 through the collection pipe 93 and the collection hood 94, thereby reducing the probability of dust, fumes, etc. polluting the working environment and even endangering the physical health of personnel.

[0038] In order to reduce the probability of the conveyor belt shifting in position, insertion blocks 10 are fixedly provided on the side walls on both sides of the base 1. The conveyor belts (not shown in the figure) on both sides of the base 1 are inserted into the insertion blocks 10, so that the conveyor belts are connected to the base 1, thereby reducing the probability of the conveyor belt shifting in position.

[0039] In order to enhance the stability of the connection between the conveyor belt and the base 1, the cross-section of the insertion block 10 is in the shape of a dovetail. The dovetail-shaped insertion block 10 prevents the conveyor belt from detaching from the base 1 from the side, thereby enhancing the stability of the connection between the conveyor belt and the base 1.

[0040] The working principle of a laser welding mechanism for a battery temperature switch in this embodiment is as follows: When laser welding of the battery temperature switch is required, the worker places the welding mold on the conveyor belt and transports it to the base 1. The controller 5 starts the first motor 31 to drive the first screw rod to rotate. Since the first screw rod is threadedly connected to the push plate 32 and the push plate 32 is slidably connected to the inner wall of the chute 11, the push plate 32 moves along the axial direction of the first screw rod, pushing the welding mold under the laser welding machine 2. The controller 5 controls the linear motor 63 to move the positioning mold 64 downward and press it against the welding mold, enhancing the stability of the welding mold and reducing the probability of the welding position shifting during laser welding. The laser welding machine 2 welds the battery temperature switch in the welding mold. After welding is completed, the controller 5 starts the second motor 42 to drive the second screw rod to rotate, and the moving plate 43 pushes the welding mold onto another conveyor belt, eliminating the dangerous operation of manually picking and placing the welding mold and improving the efficiency of welding the battery temperature switch.
