Description

Technical Field

[0001] This utility model relates to the field of parts suction device for resistance pre-welding machines, and specifically to a suction head device. Background Technology

[0002] Resistance pre-welding machines are mainly used for pre-spot welding of larger tubes and shells before parallel seam welding, such as rectangular microelectronic devices, optoelectronic devices, and flat metal tubes. Existing resistance pre-welding machines typically employ a vacuum adsorption device and a welding wheel in their suction head assembly. During operation, the vacuum adsorption device lowers to adsorb the cover plate, and the welding wheel lowers and contacts the cover plate. Through pulsed discharge, the cover plate and the tube shell are spot-welded together. However, the lifting and lowering of the vacuum adsorption device and welding wheel in existing suction head assemblies are driven by separate lifting modules. Furthermore, the lifting modules are expensive, resulting in a high overall cost for the suction head assembly. Additionally, the large size of the lifting modules occupies a significant amount of space, thus limiting its application. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a suction head device that meets the requirements of vacuum adsorption device and welding wheel lifting, while reducing costs, making the structure more compact, and reducing the space occupied.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A suction head device includes a longitudinal movement module, an adjusting seat, a lifting module, a lifting seat, a lifting component, a first connecting seat, a welding wheel device, a second connecting seat, a connector, a first buffer spring, a motor, and a vacuum adsorption device. The longitudinal movement module is used to drive the adjusting seat to move longitudinally. The lifting module is mounted on the adjusting seat and is used to drive the lifting seat to rise and fall. The lifting component is mounted on the lifting seat and is used to drive the first connecting seat to rise and fall. The welding wheel device is mounted on the first connecting seat.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0017] like Figure 1-3As shown, a suction head device includes a longitudinal movement module 1, an adjusting seat 2, a lifting module 5, a lifting seat 28, a lifting component 6, a first connecting seat 8, a welding wheel device 12, a second connecting seat 9, a connector 15, a first buffer spring 13, a motor 10, and a vacuum adsorption device 11. The longitudinal movement module 1 is used to drive the adjusting seat 2 to move longitudinally. The lifting module 5 is mounted on the adjusting seat 2 and is used to drive the lifting seat 28 to rise and fall. The lifting component 6 is mounted on the lifting seat 28 and is used to drive the first connecting seat 8 to rise and fall. The welding wheel device 12 is mounted on the first connecting seat 8. The second connecting seat 9 is connected to the connector 15, and the connector 15 is movably mounted on the lifting seat 28. The first buffer spring 13 is disposed between the lifting seat 28 and the second connecting seat 9. The motor 10 is mounted on the second connecting seat 9, and the vacuum adsorption device 11 is connected to the output shaft of the motor 10.

[0018] In use, after the vacuum adsorption device 11 picks up the cover plate, the longitudinal movement module 1 drives the adjustment seat 2, together with the vacuum adsorption device 11 and the welding wheel device 12, to move longitudinally. This allows for fine adjustment of the cover plate so that it is directly above the corresponding tube shell. Then, the lifting module 5 drives the lifting seat 28 to descend, thereby causing the vacuum adsorption device 11 and the welding wheel device 12 to descend and contact the cover plate with the tube shell. After the cover plate contacts the tube shell, the lifting module 5 continues to drive the lifting seat 28 to descend, causing the vacuum adsorption device 11 to move upward relative to the lifting seat 28. The first buffer spring 13 is compressed and applies a downward elastic force to the second connecting seat 9, so that the cover plate fits tightly against the tube shell under the elastic force of the first buffer spring 13. Then, the lifting component 6 drives the first connecting seat 8 to rise and fall, which drives the welding wheel device 12 to descend until it contacts the cover plate. Through pulse discharge of the welding wheel device 12, the cover plate and the tube shell are spot welded together. Therefore, the suction head device provided by this utility model, by combining a longitudinal moving module 1, an adjusting seat 2, a lifting module 5, a lifting seat 28, a lifting component 6, a first connecting seat 8, a welding wheel device 12, a second connecting seat 9, a connecting piece 15, a first buffer spring 13, a motor 10, and a vacuum adsorption device 11, allows the vacuum adsorption device 11 and the welding wheel device 12 to share the lifting module 5. This satisfies the lifting requirements of the vacuum adsorption device 11 and the welding wheel device 12 without requiring separate lifting modules 5 for each device, thus reducing the number of lifting modules 5 required, lowering costs, making the structure more compact, and reducing the space occupied. Furthermore, the longitudinal position of the vacuum adsorption device 11 and the welding wheel device 12 can be adjusted synchronously through the longitudinal movement module 1, and the lifting module 5 can drive the vacuum adsorption device 11 and the welding wheel device 12 to rise and fall synchronously. Thus, the longitudinal movement module 1 and the lifting module 5 can achieve precise positioning of the vacuum adsorption device 11 and the welding wheel device 12 with multiple degrees of freedom, adapting to the complex assembly requirements of small-sized components. In addition, the motor 10 can drive the vacuum adsorption device 11 to rotate and finely adjust the position of the cover plate. Through the combination of the connector 15, the lifting seat 28, the first buffer spring 13, and the second connecting seat 9, the cover plate can be tightly fitted to the tube shell under the elastic force of the first buffer spring 13, improving the spot welding effect.

[0019] The suction head device includes a sliding guide 4, and the adjusting seat 2 is slidably engaged with the sliding guide 4 to make the adjusting seat 2 slide more smoothly.

[0020] The lifting component 6 includes a cylinder. By using a cylinder for the lifting component 6, the first connecting seat 8 can be lifted and lowered simultaneously, and installation is also convenient.

[0021] A receiving seat 23 is connected to the piston rod of the cylinder, and an attachment 20 is connected to the receiving seat 23. A through hole is provided on the first connecting seat 8 for the attachment 20 to pass through. A second buffer spring 14 is provided between the attachment 20 and the first connecting seat 8. Specifically, the attachment 20 includes a first connecting bolt 21 and a washer 22; the lower end of the first connecting bolt 21 is threaded onto the receiving seat 23; the washer 22 is fitted onto the first connecting bolt 21, and the second buffer spring 14 abuts against the washer 22. By adopting the above structure, the first connecting bolt 21 and the second buffer spring 14 can be easily disassembled and assembled, facilitating maintenance and replacement.

[0022] The second buffer spring 14 is sleeved on the first connecting bolt 21.

[0023] The connector 15 includes a second connecting bolt.

[0024] Specifically, the vacuum adsorption device 11 includes a suction needle.

[0025] The lifting seat 28 is provided with a first linear guide rail 24, and the first connecting seat 8 is provided with a first slider that slides in cooperation with the first linear guide rail 24.

[0026] The lifting seat 28 includes a back seat, a front seat, a first side plate, and a second side plate. The back seat is connected to the output end of the lifting module 5. The first side plate is connected between one side of the back seat and the front seat, and the second side plate is connected between the other side of the back seat and the front seat. A second linear guide rail 26 is provided on the front seat, and a second slider 27 that slides with the second linear guide rail 26 is provided on the second connecting seat 9. The cylinder body is located within the cavity formed by the back seat, the front seat, the first side plate, and the second side plate to further reduce the volume and save space.
