Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing, in particular to a welding table for automobile ignition coils. Background Art

[0002] The processing of auto parts lays the foundation for the subsequent overall production and manufacturing of automobiles. Each auto part directly affects the performance and safety of the entire vehicle. Auto parts include intake valves, engines, cylinder blocks, and automobile ignition coils. When processing automobile ignition coils, a welding table is required. When welding automobile ignition coils, the stability of the electrical connection of the automobile ignition coils can be improved. The welding process provides a reliable electrical path and also improves the durability and reliability of the automobile ignition coils, thereby extending the service life of the automobile ignition coils.

[0003] When the welding table is working, it is necessary to quickly clamp the automobile ignition coil. Due to differences in vehicle models, the sizes of automobile ignition coils will also be different. At the same time, due to differences in engine types and performance differences, the sizes of automobile ignition coils will also be different. Therefore, the welding table needs to quickly adapt to automobile ignition coils of different sizes, otherwise it will affect the processing efficiency. In order to overcome the above-mentioned defects, prior art 1 (application number CN202023141127.5, Chinese patent application date 2020-12-22) is a welding table for automobile ignition coils. It uses a connecting plate and a screw rod in conjunction with a driving structure to fix the welding table when welding the automobile ignition coil. The staff only needs to place the ignition coil directly on the placement table, so that the longer sides of the automobile ignition coil can be clamped and fixed by the relative fixing blocks without deliberate adjustment. The placement of the ignition coil allows it to be clamped and fixed, thereby simplifying the use steps of the welding table and improving the overall work efficiency of the welding process. Prior art 2 (application number CN202220171991.X, application date 2022-01-22) is a Chinese patent for a welding table for an automobile ignition coil. It can place the ignition coil in the clamping plate by pulling outward with two sets of clamping plates and then release it. At this time, the clamping plate can be pushed to clamp the ignition coil by the rebound of the spring. The clamping operation is simple and convenient, stable and reliable, and greatly improves the welding efficiency. The exhaust fan can be started during welding. At this time, the smoke generated by welding can be drawn in through the smoke inlet and finally discharged through the hose, which can be connected to the outside, thereby preventing the welding smoke in the factory from causing harm to the human body, improving the production environment, and enhancing the protection of workers. There is also prior art 3 (application number CN202420243509.8, Chinese patent application date: 2024-01-31) A car ignition coil welding station, which places the ignition coil between a first rotating plate and a second rotating plate, rotates a hand wheel to drive the screw to rotate, the screw drives the first slider and the second slider thereon to move synchronously relative to each other, the first slider and the second slider drive the first clamping plate and the second clamping plate to move synchronously relative to each other, the first clamping plate and the second clamping plate drive the first rotating plate and the second rotating plate to move synchronously relative to each other until the first rotating plate and the second rotating plate clamp the ignition coil welding part, so that the ignition coil is clamped and fixed between the first rotating plate and the second rotating plate, which is beneficial to improving the clamping efficiency. The welding process produces harmful gases, which contain particulate matter that can affect the operator's respiratory tract and lungs. It also contains carcinogens. Long-term inhalation of these particles may increase the risk of cancer. The device in the aforementioned application uses a single fan for exhaust, resulting in low efficiency and a poor fume exhaust structure, which can affect the operator's health. Furthermore, a large amount of welding slag is generated during welding, and the device in the aforementioned application lacks a welding exhaust collection function, increasing the subsequent workload of the operator. Summary of the Invention

[0012] Preferably, the blanking assembly includes a circular plate fixedly connected to the lower surface of the connecting shaft, and the lower surface of the circular plate is fixedly connected with a fixed block, and the fixed block is a hemispherical structure, and the fixed blocks are evenly spaced on the lower surface of the circular plate.

[0014] Preferably, a torsion spring having an elastic reset function is fixedly connected to the surface of the connecting shaft, and the other side of the torsion spring is fixedly connected to the inner wall of the external connecting plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the welding table for automobile ignition coils adopts a new structural design. Through the motor, side plates, threaded rods and limit rods, the working plates and clamping plates on the left and right sides are brought close to each other, and finally the clamping plates clamp and fix the workpiece. At the same time, a gas exhaust component is provided, so that harmful gases in the welding process can be quickly discharged without affecting the health of the workers. In addition, a blanking component is provided, so that the welding slag generated in the welding process can be quickly discharged without residue, which is convenient for the later cleaning of the workers and improves the work efficiency of the workers. The specific contents are as follows:

[0016] When the automobile ignition coil welding table is in operation and needs to clamp the automobile ignition coil, the motor needs to be started. At this time, the side plates move toward the middle position of the bottom plate under the action of the threaded rod and the limit rod, and then the working plates and clamping plates on the left and right sides approach each other. Finally, the clamping plates clamp and fix the workpiece. The operation process is quick and convenient, and the work efficiency is high.

[0017] Furthermore, after the workpiece is clamped and fixed, the welding head is controlled by the robotic arm to achieve welding of the workpiece, which is convenient for operation.

[0018] The welding table for automobile ignition coils can absorb the fume generated during the welding process through the suction head, thereby optimizing the working environment of the staff and protecting their health.

[0019] Furthermore, after welding is completed, the motor rotates, and the working plate moves back. When the working plate is driven to move by the side plate, the connecting shaft rotates inside the external plate under the action of the traction rope. At this time, the long pin rotates under the action of the first bevel gear and the second bevel gear, and then the force plate and the push rod perform reciprocating linear motion in the vertical direction under the action of the cam, its own gravity and the connecting rod. At this time, the pipe sleeve and the adsorption head swing around the auxiliary rod under the thrust of the push rod and its own gravity. At this time, the working range of the adsorption head increases, which can better absorb the smoke. When working, the positioning plate limits the maximum downward rotation angle of the adsorption head, thereby improving stability.

[0020] The welding table for the automobile ignition coil has a structure in which welding slag falls onto a receiving plate during welding. The upper surface of the receiving plate is in an arc-shaped structure, so that the receiving plate can quickly discharge the welding slag, making it easy for the welding slag to be discharged from the discharge port and then quickly collected by the staff.

[0021] Furthermore, when the connecting shaft rotates, the connecting shaft drives the circular plate and the fixed block to rotate synchronously. When the fixed block rotates to push the upper connecting block, the upper connecting block and the material receiving plate descend under the action of the thrust. At this time, the connecting spring will be compressed, and when the fixed block continues to rotate until it does not push the upper connecting block, the material receiving plate returns to its original position under the action of the connecting spring, and then the material receiving plate is in a shaking state, which facilitates quick unloading, makes it easier to discharge welding slag, and improves work efficiency.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0034] The present invention provides the following technical solution: a welding table for an automobile ignition coil.

[0035] Embodiment 1: By setting the motor 4, the working plates 6 and the clamping plates 7 on the left and right sides can be brought closer to each other, and finally the workpiece can be clamped and fixed. Figure 1-Figure 3 As shown: It includes a base plate 1, a bracket is fixedly connected to the lower surface of the base plate 1, and a fence 2 is fixedly connected to the upper surface of the base plate 1, and a mechanical arm 3 is bolted to the inner wall of the fence 2, and the end of the mechanical arm 3 is bolted to the welding head, and a motor 4 and a threaded rod 5 are bolted to the outer wall of the fence 2.

[0036] During work, when it is necessary to clamp the automobile ignition coil, the motor 4 needs to be started. At this time, the side plate 9 moves to the middle position of the bottom plate 1 under the action of the threaded rod 5 and the limit rod 10, and then the working plates 6 and the clamping plates 7 on the left and right sides approach each other. Finally, the clamping plate 7 clamps and fixes the workpiece. The operation process is quick and convenient, and the work efficiency is high. After the workpiece is clamped and fixed, the welding head is controlled by the robotic arm 3 to achieve welding of the workpiece, which is easy to operate.

[0037] Embodiment 2: Different from embodiment 1, the gas exhaust component is provided to quickly collect and remove the harmful gases generated during welding, thus optimizing the working environment. Figure 4-Figure 6As shown: the gas exhaust assembly also includes a first bevel gear 13 fixedly connected to the upper surface of the connecting shaft 12, a traction rope 21 is fixedly connected to the inner wall of the enclosure 2, and the other side of the traction rope 21 is wrapped and fixedly connected to the surface of the connecting shaft 12, a long pin 14 is provided for rotation inside the working plate 6, and the end of the long pin 14 is fixedly connected to the second bevel gear 15 meshing with the first bevel gear 13, a cam 16 is fixedly connected to the surface of the long pin 14, a connecting rod 18 is fixedly connected to the surface of the working plate 6, and the front view of the connecting rod 18 is an inverted "L" structure, and a force plate 17 is slidingly provided on the surface of the connecting rod 18, and the upper surface of the force plate 17 is fixedly connected to a push rod 22.

[0038] An auxiliary rod 23 is fixedly connected to the surface of the working plate 6, and the auxiliary rod 23 is an inverted "U" shape when viewed from above, and a pipe sleeve 24 is fixedly connected to the surface of the auxiliary rod 23, and the surface of the pipe sleeve 24 is fixedly connected to the adsorption head 19, and the surface of the adsorption head 19 is fixedly connected to the delivery pipe 20, and the delivery pipe 20 is connected to the output end of the gas treatment device through an external hose, and a positioning plate 25 is fixedly connected to the surface of the working plate 6.

[0039] When welding is in progress, the suction head 19 can absorb the fume generated during the welding process, thereby optimizing the working environment of the staff and protecting the health of the staff. After the welding is completed, the motor 4 rotates, and the working plate 6 moves back. When the working plate 6 is driven to move by the side plate 9, the connecting shaft 12 rotates inside the external plate 11 under the action of the traction rope 21 and the torsion spring 33. At this time, the long pin 14 rotates under the action of the first bevel gear 13 and the second bevel gear 15. At this time, the long pin 14 drives the cam 16 to rotate synchronously. When the cam 16 rotates to push the force-bearing plate 17, the force-bearing plate 17 rises, and when the cam 16 continues to rotate to stop pushing the force-bearing plate 17, the force-bearing plate 17 drops under the action of its own gravity, and then the force-bearing plate 17 and the push rod 22 make reciprocating linear motion in the vertical direction under the action of the cam 16, their own gravity and the connecting rod 18. At this time, the pipe sleeve 24 and the adsorption head 19 swing around the auxiliary rod 23 under the thrust of the push rod 22 and their own gravity. At this time, the working range of the adsorption head 19 is increased, which can better absorb the smoke.

[0040] Embodiment 3: The difference from embodiment 2 is that the welding slag is quickly discharged during the welding process by setting a blanking component, so that it is easy to be collected by the staff. Figure 7-10As shown, the blanking assembly includes a circular plate 31 fixedly connected to the lower surface of the connecting shaft 12, and the lower surface of the circular plate 31 is fixedly connected to a fixed block 32, and the fixed block 32 is a hemispherical structure, and the fixed blocks 32 are evenly spaced on the lower surface of the circular plate 31, the upper connecting blocks 27 are symmetrically distributed about the center of the receiving plate 8, and the upper surface of the receiving plate 8 is an arc structure, the upper surface of the bottom plate 1 is fixedly connected to a column 28, and the column 28 passes through the interior of the receiving plate 8, and the upper surface of the column 28 is fixedly connected to a baffle 30, the lower surface of the receiving plate 8 is fixedly connected to a connecting spring 29, and the other side of the connecting spring 29 is fixedly connected to the upper surface of the bottom plate 1, and a blanking port 26 is opened on the surface of the bottom plate 1, the surface of the connecting shaft 12 is fixedly connected to a torsion spring 33 that plays an elastic reset role, and the other side of the torsion spring 33 is fixedly connected to the inner wall of the external connecting plate 11.

[0041] When welding, the welding slag will fall onto the receiving plate 8, and the upper surface of the receiving plate 8 is an arc structure, so the receiving plate 8 can quickly discharge the welding slag, which is convenient for the welding slag to be discharged from the discharge port 26, thereby facilitating the rapid collection of the staff. When the connecting shaft 12 rotates, the connecting shaft 12 drives the circular plate 31 and the fixed block 32 to rotate synchronously. When the fixed block 32 rotates to push the upper connecting block 27, the upper connecting block 27 and the receiving plate 8 fall down under the thrust. At this time, the connecting spring 29 will be compressed, and when the fixed block 32 continues to rotate until it does not push the upper connecting block 27, the receiving plate 8 returns to its original position under the action of the connecting spring 29, and then the receiving plate 8 performs reciprocating linear motion in the vertical direction under the action of the thrust and elastic force as well as the column 28 and the baffle 30, that is, the receiving plate 8 is in a shaking state, which is convenient for rapid unloading, makes it easier to discharge the welding slag, and improves work efficiency.

[0042] When the connecting shaft 12 rotates, the torsion spring 33 is stretched, and then the motor 4 rotates. When the working plate 6 and the external plate 11 move back, the connecting shaft 12 rotates under the action of the torsion spring 33. When the connecting shaft 12 rotates, the traction rope 21 is reeled in for the next use. At the same time, when the connecting shaft 12 rotates, the above process occurs again, thereby improving work efficiency.

[0043] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
