Description

Technical Field

[0001] This invention relates to the field of electronic component manufacturing technology, specifically to a spot welding machine for manufacturing electronic components. Background Technology

[0002] Electric welding machines are a common type of welding equipment. Spot welding machines use a power source to generate a strong current, which is injected into the electrode through a conductive copper wire. This causes the electrode to generate high temperatures and melt the metal, connecting two or more metal parts. Simply place the components to be welded in the appropriate position, press the button, and wait a few seconds to weld the components. Compared to traditional gas shielded welding and manual argon arc welding, spot welding machines greatly save time and manpower. Existing patent document CN214518133U discloses a high-efficiency spot welding device for manufacturing electronic components, including a spot welding machine base. A spot welding frame is fixedly mounted at one end of the top of the spot welding machine base. A transmission base is fixedly mounted on the inner side of the spot welding frame. A transmission screw is rotatably connected to the inner side of the transmission base. A transmission slider is threadedly connected to the middle of the transmission screw. A lifting frame is fixedly mounted on the front of the transmission slider. A lifting slide is slidably connected to the inner side of the lifting frame. An electric telescopic push rod is fixedly installed on the top of the lifting frame. A spot welding device is fixedly installed on the bottom of the lifting slide. The welding machine head has a geared motor fixedly installed on the outer side of the spot welding machine frame. A spot welding turntable is rotatably connected to the center of the top of the spot welding machine table.

L-shaped brackets are fixedly installed at the four corners of the top of each component mounting seat. A control panel is fixedly installed on one side of the top of the spot welding machine table. A power distribution box is fixedly installed at the bottom of the spot welding machine table. A drive motor is fixedly installed on the top of the inner wall of the power distribution box. A controller is fixedly installed on the bottom of the inner wall of the power distribution box. A fuse, an electricity meter, a voltage regulator, and a relay are fixedly installed on one side of the inner wall of the power distribution box. Regarding the aforementioned related technologies, the inventors have discovered that the technologies have at least the following problems: the spot welding machine in the aforementioned patent documents cannot clamp and fix the components, and during the spot welding process, the components may be lifted by the electrodes of the spot welding machine, causing inconvenience in use. Summary of the Invention

[0003] The purpose of this invention is to provide a spot welding machine for manufacturing electronic components, so as to solve the problem mentioned in the background art that the components cannot be clamped and may be carried out by the electrodes of the spot welding machine.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a spot welding machine for manufacturing electronic components, comprising a machine body, a support platform fixedly installed at one end of the machine body, a door rotatably installed on the side surface of the machine body, and an air inlet groove fixedly installed on the upper outer surface of the machine body. A guide rod is provided between the machine body and the support platform, and a placement platform is slidably installed on the outer surface of the guide rod. A clamping mechanism is installed on the outer surface of the placement platform, and multiple components are fixed to the outer surface of the placement platform by the clamping mechanism.

[0005] Preferably, the clamping mechanism includes a clamping plate, which is rotatably mounted on the upper end of the placement platform. A support column is provided at the lower end of the placement platform, and a roller is rotatably mounted on the support column at the lower end of the placement platform. A connecting rod is slidably mounted on the end of the placement platform away from the clamping plate, and protrusions are evenly provided on the outer surface of the connecting rod on the side near the placement platform. A return spring is fixedly installed inside the placement platform, and one end of the return spring is connected to the connecting rod.

[0006] By adopting the above technical solution, components can be automatically clamped while the placement stage moves.

[0007] Preferably, a pushing mechanism is slidably mounted on the outer surface of the placement platform, and the size of the placed component is adapted by adjusting the pushing mechanism.

[0008] By adopting the above technical solution, components of different sizes can be clamped when changing the type of components.

[0009] Preferably, the pushing mechanism includes a sliding clamp plate, which is slidably mounted on the side of the placement platform away from the roller, and a set screw is threadedly connected to the outer surface of the placement platform, with one end of the set screw being rotatably connected to the sliding clamp plate. The return spring is located on the side of the placement platform away from the sliding clamp plate.

[0010] Using the above technical solution, the distance between the sliding clamp and the clamping plate can be adjusted by tightening the set screw.

[0011] Preferably, a displacement mechanism is fixedly installed inside the placement platform, which drives the placement platform to move in and out of the machine body.

[0012] Using the above technical solution, the placement platform can be sent into the interior of the machine body.

[0013] Preferably, the displacement mechanism includes a stepper motor, which is fixedly installed inside the placement platform. A synchronous pulley is fixedly installed at the output end of the stepper motor. One of the synchronous pulleys is rotatably installed inside the machine body. A synchronous belt is provided between the two synchronous pulleys, and a section of the outer surface of the synchronous belt is fixedly connected to the lower end of the placement platform.

[0014] Using the above technical solution, the placement platform can be moved smoothly by the guide rod.

[0015] Preferably, an exhaust fan is fixedly installed inside the machine body, and a replacement drawer is slidably installed above the exhaust fan inside the machine body, with a filter plate engaged inside the replacement drawer.

[0016] By adopting the above technical solution, the air can be filtered through the filter plate when the exhaust fan draws in the outside air. At the same time, the filter plate can be removed and cleaned by changing the drawer to prevent dust particles from entering the machine body.

[0017] Compared with the prior art, the beneficial effects of the present invention are: the spot welding machine for manufacturing electronic components: 1. Place multiple components to be processed sequentially on the top of the placement table, and place the components between the clamping plate and the sliding clamping plate. After placement, the placement table enters the machine body, and one end of the linkage rod disengages from the side surface of the placement table. At this time, the return spring will push the linkage rod to drive the protrusion block. The protrusion block squeezes the roller, lifting the clamping plate and clamping the components. As the placement table moves, the components are automatically clamped to prevent them from being lifted by the electrodes of the welding machine during welding. 2. After the components are placed, the stepper motor starts and rotates, which drives the synchronous pulley to rotate. The rotation of the synchronous pulley drives the synchronous belt to move, and the movement of the synchronous belt drives the placement table to move. The table smoothly enters the machine body through the guide rod without causing any bumps. 3. When it is necessary to change the size of the component, simply move the placement stage into the machine body, place the component between the clamping plate and the sliding clamping plate, then adjust the set screw, and by rotating the set screw, push the sliding clamping plate forward and move towards the component to clamp the component, thereby adjusting the size of the clamped component. 4. During the spot welding process, when the columnar electrode contacts the two overlapping workpieces, the surface in contact with the electrode is melted and cooled by the resistance heating of the large current and then connected. During the discharge welding process, electric sparks will inevitably be splashed out. At this time, the electric sparks will fall into the closed machine body, and due to the obstruction of the door, they cannot fly out of the machine body, preventing the electric sparks from splashing onto flammable materials and causing combustion. 5. When the placement platform enters the machine body, heat will inevitably be generated during the welding process of the spot welding machine. At this time, the exhaust fan can be used to draw in the air from outside the machine body through the air inlet slot, filter the dust particles in the air through the filter plate, and blow out the hot air generated inside the machine body to reduce the temperature inside the machine body and the temperature of the welding components.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-7 The present invention provides a technical solution: a spot welding machine for manufacturing electronic components.

[0022] Example 1: This example discloses: A support platform 2 is fixedly installed at one end of the body 1, and a door 3 is rotatably installed on the side surface of the body 1. An air inlet slot 4 is fixedly installed on the upper outer surface of the body 1. A guide rod 5 is provided between the body 1 and the support platform 2, and a placement platform 6 is slidably installed on the outer surface of the guide rod 5. A clamping mechanism is installed on the outer surface of the placement platform 6. Multiple components are fixed on the outer surface of the placement platform 6 through the clamping mechanism. The clamping mechanism includes a clamping plate 7, which is rotatably installed on the upper end of the placement platform 6. A support column is provided at the lower end of the placement platform 6, and a roller 10 is rotatably installed on the support column at the lower end of the placement platform 6. A connecting rod 11 is slidably installed at the end of the placement platform 6 away from the clamping plate 7, and protrusions 12 are evenly provided on the outer surface of the connecting rod 11 on the side close to the placement platform 6. A return spring 13 is fixedly installed inside the placement platform 6, and one end of the return spring 13 is connected to the connecting rod 11.

[0023] When using the device, one end of the linkage rod 11 will be in contact with the inner surface of the support platform 2, and the clamping plate 7 will fall and open due to gravity. Then, the component can be placed on the clamping plate 7 and placed between the clamping plate 7 and the sliding clamping plate 8. When the stepper motor 14 is started, it will send the placement platform 6 into the interior of the machine body 1. When the placement platform 6 moves, the return spring 13 will push the linkage rod 11 back, causing the linkage rod 11 to drive the protrusion 12 to move. The protrusion 12 squeezes the roller 10, causing the clamping plate 7 to rotate and rise to clamp the component. The placement platform 6 clamps the component while moving, preventing it from being lifted by the electrodes of the spot welding machine during spot welding.

[0024] Example 2: This example is based on Example 1: A pushing mechanism is slidably installed on the outer surface of the placement platform 6. The size of the component is adapted to be placed by adjusting the pushing mechanism. The pushing mechanism includes a sliding clamp 8, which is slidably installed on the side of the placement platform 6 away from the roller 10. A set screw 9 is threadedly connected to the outer surface of the placement platform 6, and one end of the set screw 9 is rotatably connected to the sliding clamp 8. The reset spring 13 is located on the side of the placement platform 6 away from the sliding clamp 8.

[0025] By adding the above structure, when it is necessary to change the clamping size, simply move the placement platform 6 into the interior of the machine body 1, then open the compartment door 3, place the component between the clamping plate 7 and the sliding clamping plate 8, then rotate the set screw 9 to push out the sliding clamping plate 8 and clamp the component. After the adjustment is completed, move the placement platform 6 above the receiving platform 2 and take out the component to complete the change and adjustment of the component size.

[0026] Example 3: This example is based on Examples 1 and 2: A displacement mechanism is fixedly installed inside the placement platform 2. The displacement mechanism drives the placement platform 6 to move in and out of the machine body 1. The displacement mechanism includes a stepper motor 14, which is fixedly installed inside the placement platform 2. A synchronous pulley 15 is fixedly installed at the output end of the stepper motor 14. One synchronous pulley 15 is rotatably installed inside the machine body 1. A synchronous belt 16 is provided between the two synchronous pulleys 15. A section of the outer surface of the synchronous belt 16 is fixedly connected to the lower end of the placement platform 6.

[0027] By adding the above structure, when the stepper motor 14 is started, the stepper motor 14 rotates and drives the synchronous pulley 15 to rotate. The rotation of the synchronous pulley 15 drives the synchronous belt 16 to move. The movement of the synchronous belt 16 drives the placement platform 6 to move and smoothly enter the machine body 1 through the guide rod 5 without generating vibration.

[0028] Example 4: This example is based on Example 1: An exhaust fan 17 is fixedly installed inside the body 1, and a replacement drawer 18 is slidably installed inside the body 1 above the exhaust fan 17, and a filter plate 19 is engaged inside the replacement drawer 18.

[0029] By adding the above structure, external air is drawn into the machine body 1 from the air intake slot 4 by the exhaust fan 17, and dust particles in the external air are filtered by the filter plate 19 to prevent dust from entering the machine body 1. At the same time, the replacement drawer 18 can be taken out to replace and clean the filter plate 19. The hot air generated by spot welding inside the machine body 1 is carried out by the air drawn in, thereby reducing the temperature inside the machine body 1 and the temperature of the components.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
