Description

Technical Field

[0001] This utility model relates to the field of conductive plate hot-melting technology, and more specifically, to a conductive plate hot-melting device. Background Technology

[0002] In the field of electronic and electrical equipment manufacturing, conductive plates are core components for circuit connection, signal transmission, and structural support. Their processing quality directly affects the performance and reliability of the overall equipment. Hot-melt bonding, a critical process in conductive plate processing, is mainly used to achieve fixed connections between the conductive plate and other components or to locally shape the conductive plate itself. It is essential to ensure the positional accuracy, connection strength, and conductivity of the hot-melt joints to meet subsequent assembly and usage requirements.

[0003] Existing equipment mostly relies on the lifting drive structure of the hot-melt device itself to position the hot-melt head, lacking a dedicated guiding and correction mechanism. After long-term use, the hot-melt head is prone to misalignment due to wear of the drive structure, installation errors, or equipment vibration. This results in the hot-melt head failing to accurately align with the preset hot-melt position on the conductive plate, causing defects such as misalignment, localized over-melting, or incomplete fusion, affecting the connection reliability of the conductive plate. In view of this, we propose a conductive plate hot-melt device. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a conductive plate hot-melting device to solve the technical problem that the current conductive plate hot-melting device relies on the positioning of the hot-melting device itself, which easily leads to the displacement of the hot-melting head.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a conductive plate hot-melting device, including a vertically arranged hot-melting head and a hot-melting device for driving its lifting and lowering. A guide plate is provided at the bottom of the hot-melting head, and a fixing ring is provided on the outer wall of the hot-melting head. A guiding mechanism is provided inside the guide plate, and a positioning mechanism is provided at the bottom of the guiding mechanism. The guiding mechanism includes a fixed sleeve, a centering block, and a conical hopper. The fixed sleeve is fixedly installed inside the guide plate, and the conical hopper is fixedly installed on the top of the fixed sleeve. The centering block is slidably installed in the first groove corresponding to it on the fixed sleeve via a first sliding rod. The top of the centering block has an arc-shaped contact surface that forms a guiding channel. The center of the conical hopper corresponds to the guiding channel. The positioning mechanism includes a lower pressure frame, a lower pressure ring, and a lower pressure rod. The lower pressure frame is slidably installed inside the first mounting cavity opened inside the centering block. The lower pressure ring is fixedly installed to the bottom of the fixed sleeve via a corrugated pipe. The lower pressure rod is slidably installed inside the second mounting cavity corresponding to it on the lower pressure frame.

[0006] Preferably, the guiding mechanism further includes an elastic wing, the tail of which is fixedly installed to the inner wall of the fixed sleeve, and the free end of which is fixedly installed to the outer wall of the centering block.

[0007] Preferably, the positioning mechanism further includes a first spring, which is fixedly installed between the inner wall of the first mounting cavity and the lower pressure frame. A lower pressure block is fixedly installed on the inner side of the lower pressure frame. A second spring is fixedly installed between the inner wall of the second mounting cavity and the lower pressure rod. The lower pressure rod is slidably installed inside the second sliding groove corresponding to the lower pressure ring via a second sliding rod.

[0008] Preferably, the center of curvature of the arc-shaped contact surface of the centering block coincides with the axis of the hot melt head.

[0009] Preferably, the elastic winglets are sheet-like elastic structures distributed circumferentially along the centering block.

[0010] Preferably, the pressing block is disposed inside the guide channel.

[0011] Preferably, a slide rail is fixedly installed at the bottom of the hot-melt device, a sliding frame is slidably installed at the top of the slide rail, and a placement frame is fixedly installed at the top of the sliding frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a conical hopper to initially guide the hot melt head during its initial downward movement, guiding it towards a preset trajectory and reducing initial deviation. If the hot melt head still has a deviation, the arc-shaped contact surface of the centering block can provide secondary guidance, using the gradual contact characteristics of the arc surface to correct the deviation, ensuring that the hot melt head smoothly enters the guide channel formed by the centering block. The elastic wing provides a continuous elastic force when the hot melt head squeezes the centering block, ensuring that the centering block always fits tightly against the outer wall of the hot melt head, preventing the hot melt head from deviating again due to vibration or pressure changes during subsequent downward movement. This fundamentally ensures the precise alignment of the hot melt head with the hot melt part of the conductive plate, solving the problem that the hot melt equipment relies on the positioning of the hot melt device itself, which easily leads to the deviation of the hot melt head.

[0013] 2. This utility model also uses a lower pressure frame that slides within the first mounting cavity of the centering block, thereby pushing the lower pressure rod to drive the lower pressure ring to move downward. The lower pressure ring can accurately cover the heat-melting part of the conductive plate and make initial contact, thus achieving pre-fixation of the conductive plate and preventing displacement of the conductive plate when the heat-melting head is pressed down. The second spring can adaptively buffer according to the heat-melting pressure, keeping the pressing force of the lower pressure ring stable. This ensures reliable fixing of the conductive plate and avoids damaging the surface of the conductive plate, laying the foundation for subsequent precise heat melting. Attached Figure Description

[0016] Example: Figures 1 to 6As shown, this utility model relates to a conductive plate hot-melting device, including a vertically arranged hot-melting head 5 and a hot-melting device 1 for driving its lifting and lowering. A guide plate 4 is provided at the bottom of the hot-melting head 5, and a fixing ring 51 is provided on the outer wall of the hot-melting head 5. A guiding mechanism 2 is provided inside the guide plate 4, and a positioning mechanism 3 is provided at the bottom of the guiding mechanism 2. A slide rail 11 is fixedly installed at the bottom of the hot-melting device 1, and a sliding frame 12 is slidably installed on the top of the slide rail 11. A placement frame 13 is fixedly installed on the top of the sliding frame 12. The guiding mechanism 2 includes a fixed sleeve 21, a centering block 23, and a conical bucket 25. The fixed sleeve 21 is fixedly installed inside the guide plate 4, and the conical bucket 25 is fixedly installed on the top of the fixed sleeve 21. The centering block 23 is slidably installed inside the first sliding groove 241 corresponding to it on the fixed sleeve 21 via a first sliding rod 24. The top of the centering block 23 has an arc-shaped contact surface 231 forming a guiding channel. The center of curvature of the arc-shaped contact surface 231 of the centering block 23 coincides with the axis of the hot-melting head 5. The center of the conical bucket 25 corresponds to the guide channel. The positioning mechanism 3 includes a pressure frame 32, a pressure ring 35, and a pressure rod 37. The pressure frame 32 is slidably installed inside the first mounting cavity 232 opened inside the centering block 23. The pressure ring 35 is fixedly installed to the bottom of the fixed sleeve 21 through the corrugated pipe 34. The pressure rod 37 is slidably installed inside the second mounting cavity 322 opened corresponding to the pressure frame 32. This utility model can initially guide the hot melt head 5 in the early stage of its downward movement through the conical bucket 25, guiding the hot melt head 5 to approach the preset trajectory and reducing the initial offset. If the hot melt head 5 still has a deviation, the arc-shaped contact surface 231 of the centering block 23 can provide secondary guidance, using the gradual contact characteristics of the arc surface to correct the offset, ensuring that the hot melt head 5 smoothly enters the guide channel formed by the centering block 23. This fundamentally ensures the accurate alignment of the hot melt head 5 with the hot melt part of the conductive plate, solving the problem that the hot melt head 5 is prone to offset due to the hot melt device 1's self-positioning in the hot melt equipment.

[0017] Furthermore, such as Figures 2 to 4 As shown, the guide mechanism 2 also includes an elastic wing 22. The tail of the elastic wing 22 is fixedly installed on the inner wall of the fixed sleeve 21, and the free end of the elastic wing 22 is fixedly installed on the outer wall of the centering block 23. The elastic wing 22 is a sheet-like elastic structure distributed circumferentially along the centering block 23. The elastic wing 22 provides a continuous elastic force when the hot melt head 5 squeezes the centering block 23, so that the centering block 23 always fits tightly against the outer wall of the hot melt head 5, preventing the hot melt head 5 from shifting again due to vibration or pressure changes during subsequent downward movement.

[0018] Furthermore, such as Figures 5 to 6As shown, the positioning mechanism 3 also includes a first spring 31, which is fixedly installed between the inner wall of the first mounting cavity 232 and the lower pressure frame 32. A lower pressure block 321 is fixedly installed on the inner side of the lower pressure frame 32 and is located inside the guide channel. A second spring 36 is fixedly installed between the inner wall of the second mounting cavity 322 and the lower pressure rod 37. The lower pressure rod 37 is slidably installed inside the second sliding groove 331 corresponding to the lower pressure ring 35 through the second sliding rod 33. The lower pressure frame 32 slides in the first mounting cavity 232 of the centering block 23, thereby pushing the lower pressure rod 37 to drive the lower pressure ring 35 to move down. The lower pressure ring 35 can accurately cover the hot-melt part of the conductive plate and make contact first, realizing the pre-fixation of the conductive plate and avoiding displacement of the conductive plate when the hot-melt head 5 is pressed down. The second spring 36 can adaptively buffer according to the hot-melt pressure, so that the pressing force of the lower pressure ring 35 remains stable, ensuring that the conductive plate is fixed reliably and avoiding damage to the surface of the conductive plate, laying the foundation for subsequent accurate hot-melt.

[0019] Working principle: This embodiment provides a conductive plate hot melting device. When in use, the conductive plate to be hot melted is placed inside the placement rack 13, the sliding rack 12 is pushed along the slide rail 11 to the bottom of the guide plate 4, and the hot melting device 1 is started, so that the hot melting head 5 moves down.

[0020] During the downward movement of the hot melt head 5, the conical bucket 25 is used to guide the hot melt head 5. The hot melt head 5 continues to move downward. If there is any deviation during the downward movement of the hot melt head 5, it will enter the channel surrounded by the centering block 23 under the secondary guidance of the arc-shaped contact surface 231. At this time, the hot melt head 5 will squeeze the periphery of the centering block 23. At this time, the elastic wing 22 is used to squeeze the centering block 23, so that the centering block 23 continues to squeeze the hot melt head 5 to prevent the hot melt head 5 from deviating.

[0021] During the downward movement of the hot melt head 5, the fixing ring 51 fixedly installed on the outside of the hot melt head 5 will contact the lower pressure block 321 inside the channel. At this time, the lower pressure frame 32 will slide inside the first mounting cavity 232 opened inside the centering block 23, thereby causing the lower pressure rod 37 to push the lower pressure ring 35 down, so that the lower pressure ring 35 covers the part of the conductive plate that needs to be hot melted and contacts it, squeezing the lower pressure ring 35. The lower pressure ring 35 squeezes the second spring 36 through the lower pressure rod 37, thereby causing the lower pressure rod 37 to slide inside the second mounting cavity 322. At this time, the hot melt head 5 continues to press down to perform the hot melt operation on the conductive plate.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
