Description

Technical Field

[0001] This utility model relates to the field of PCB manufacturing technology, and in particular to a PCB detachable welding fixture and production line. Background Technology

[0002] Printed circuit boards (PCBs) are one of the core components of electronic devices. They carry electronic components and transmit electronic signals through circuit connections. With the rapid development of electronic technology, the application range of PCBs is becoming increasingly wide, from small electronic devices such as Bluetooth headsets and smartwatches to large equipment such as computers, communication equipment, and military / aerospace systems. Automated soldering is a crucial step in the PCB production process. The use of carriers is indispensable in automated soldering. Currently, the carrier body design commonly used in the market is a one-piece design. This design has significant problems in practical applications: because the carrier needs to be in direct contact with the soldering equipment during operation, friction is inevitable. If the carrier is made of a highly wear-resistant material, although wear can be reduced, it may damage the soldering equipment, thus affecting the normal service life and performance of the equipment. On the other hand, if the wear resistance of the carrier is lower than that of the soldering equipment, the carrier will show significant wear over a long period of friction. Because traditional carriers use a one-piece design, once a part wears out, the entire carrier needs to be replaced, which wastes materials and processing costs, and the replacement process is cumbersome and difficult to repair. In addition, frequent vehicle changes can affect production efficiency and increase the company's operating costs.

[0003] Therefore, existing PCB soldering carriers need to be improved to overcome the shortcomings of the existing technology. Utility Model Content

[0004] To overcome the problems existing in related technologies, one of the objectives of this utility model is to provide a PCB detachable welding fixture. The support plate of this fixture is replaceable. After wear and tear, only the support plate needs to be replaced to enable the fixture to be used normally, avoiding the need for complete scrapping and replacement of the fixture and reducing resource waste.

[0005] A PCB detachable soldering fixture, comprising:

[0006] The base has a placement position for placing the PCB and a clamping component for pressing the PCB.

[0007] The base is also provided with a support plate, which is used to support the base on the welding equipment. The support plate is detachably connected to the base.

[0008] In practical applications, clamping components are used to secure the PCB during the soldering process, ensuring the PCB's positional accuracy and stability. The support plate's function is to support the base on the soldering equipment; the support plate can be detachably connected to the base. For example, the support plate can be quickly removed from the base using a mechanism such as screws or clips, allowing for rapid replacement of the support plate after wear without replacing the entire base. When the support plate wears to a certain extent, it can simply be removed and replaced with a new one, restoring the fixture to normal use. The fixture design reduces the need for complete replacement due to wear, effectively utilizing resources and reducing material waste. Furthermore, the quick-change support plate design reduces production line downtime and improves production efficiency.

[0009] In a preferred embodiment of this invention, two support plates are provided on the base, and the two support plates are symmetrically arranged on opposite sides of the base.

[0010] This embodiment significantly improves the stability of the fixture by symmetrically arranging two support plates on the base, reducing the problem of fixture tilting or instability caused by support plate wear. Since the PCB is firmly fixed during soldering, soldering quality is guaranteed, reducing soldering defects caused by carrier issues.

[0011] In a preferred embodiment of this invention, the base is provided with an installation groove, the support plate is embedded in the installation groove, and the support plate is detachably connected to the base by a locking member.

[0012] In this embodiment, the shape and size of the mounting groove match the support plate so that the support plate can be precisely embedded within it. This design makes the installation of the support plate easier and ensures the stability of the support plate during the welding process, significantly improving the stability of the tooling and preventing welding errors caused by the movement of the support plate.

[0013] In a preferred embodiment of this invention, a notch is provided on one side of the mounting groove, and after the support plate is embedded in the mounting groove, one side of the support plate protrudes from the notch.

[0014] One side of the support plate protrudes from the notch. During use, the protruding part of the support plate connects with the welding equipment, providing stable support for the tooling. In actual use, the width of the protruding part of the support plate is greater than 1 cm to ensure effective support for the entire tooling, thus ensuring the stability of the tooling during use and preventing welding errors caused by the movement of the support plate.

[0015] In a preferred embodiment of this invention, the locking element includes a bolt, the mounting groove has a threaded hole, the support plate has a through hole, and the bolt passes through the through hole and is threadedly connected to the threaded hole.

[0016] This embodiment provides a specific implementation of the locking component, which is a bolt. The bolt is threadedly connected to the threaded hole, which is not only convenient and quick, but also ensures the installation stability of the support plate.

[0017] In a preferred embodiment of this utility model, the clamping member includes a pressure plate and a connecting arm, the connecting arm is hinged to the base, the pressure plate is disposed on one side of the connecting arm, and the pressure plate is provided with a clamping surface.

[0018] The connecting arm is hinged to the base, allowing the pressure plate to rotate around the hinge point. The pressure plate is positioned on one side of the connecting arm to directly contact and apply pressure to the PCB, thus fixing its position. A pressing surface on the pressure plate contacts the PCB to ensure stable fixation during soldering and prevent displacement or vibration. In a preferred embodiment, a cushioning material, such as high-temperature resistant rubber, can be provided on the pressing surface to reduce damage to the PCB.

[0019] In a preferred embodiment of this invention, the pressure plate is provided with a handle and a positioning post, with the positioning post located on one side of the handle.

[0020] The handle allows operators to easily manipulate the pressure plate. A positioning post on one side of the handle provides additional stability and precision during operation, ensuring the pressure plate does not shift when pressure is applied. During soldering, the operator can grip the handle and operate the connecting arm to bring the pressure plate's clamping surface into contact with the PCB and apply appropriate pressure to secure the PCB. The positioning post ensures precise positioning of the pressure plate during operation. After soldering, the operator can lift the pressure plate to release the PCB.

[0021] In a preferred embodiment of this invention, a magnet is also provided on the base, and the magnet is located at the edge of the placement position.

[0022] The magnets provide additional holding force during the soldering process to prevent the PCB from shifting or vibrating. Positioned at the edge of the placement area, the magnets attract the PCB's edges after placement, enhancing stability. The position and number of magnets can be adjusted according to the PCB's size and shape for optimal holding. During soldering, the operator places the PCB in the placement area, and the magnets automatically attract the PCB's edges, securing it in place. The operator can then further secure the PCB using clamps. After soldering, the operator can release the clamps and magnets to remove the soldered PCB.

[0023] In another embodiment, the magnet can also be used to attract the clamping component, causing the clamping component to contact the base plate, thereby effectively clamping the PCB. In this embodiment, the magnet is disposed on the clamping component.

[0024] In a preferred embodiment of this utility model, a snap fastener is further provided on the base, and the snap fastener is disposed at the edge of the placement position;

[0025] The buckle includes a buckle body and a rotating connector, the rotating connector being pivotally connected to the base, and the buckle body being fixedly connected to the rotating connector;

[0026] The rotating connector is also provided with an elastic element, which is disposed between the rotating connector and the buckle body.

[0027] The rotating connector is pivotally connected to the base, allowing the snap fastener to rotate around it. The snap fastener body is fixedly connected to the rotating connector and directly contacts the PCB to apply pressure, thus securing the PCB in place. An elastic element is positioned between the rotating connector and the snap fastener body. The elastic element provides a restoring force when pressure is applied to the snap fastener, ensuring a tight contact between the snap fastener and the PCB and guaranteeing PCB stability. During soldering, the operator can manipulate the rotating connector to rotate the snap fastener body around it and apply pressure to the PCB. With the assistance of the elastic element, the PCB is securely fixed. After soldering, the operator rotates the rotating connector again to release the PCB.

[0028] The second objective of this utility model is to provide a PCB welding production line, including a transmission line, a welding mechanism, and a PCB-separated welding fixture as described above. The welding fixture is placed on the transmission line, and the welding mechanism is located below the transmission line.

[0029] In this production line, a conveyor line transports the soldering fixtures containing the PCBs to the soldering position. The soldering mechanism, located below the conveyor line, performs the soldering operation. As the PCB moves to the soldering position via the conveyor line, the soldering mechanism descends above the PCB and performs the soldering operation. During this process, the clamping components of the PCB-separate soldering fixture firmly hold the PCB in place, ensuring soldering accuracy.

[0030] The beneficial effects of this utility model are as follows:

[0031] This utility model provides a PCB detachable welding fixture, which includes a base with a placement position for placing the PCB and a clamping component for pressing the PCB. The clamping component is used to fix the PCB during welding, ensuring the accuracy and stability of the PCB's position. A support plate is also provided on the base to support the base on the welding equipment; the support plate is detachably connected to the base. During welding use, the support plate may gradually wear down due to contact with the welding equipment. However, the support plate in this application can be replaced separately. When the support plate wears to a certain extent, it can simply be removed and replaced with a new one, and the fixture can be restored to normal use. Through the detachable design, only the worn support plate needs to be replaced, instead of the entire fixture, significantly reducing maintenance costs. By reducing the need for complete replacement due to wear, resources are effectively utilized, and material waste is reduced. The quickly replaceable support plate also reduces production line downtime, helping to improve production efficiency.

[0032] This application also provides a PCB soldering production line, which includes a conveyor line, a soldering mechanism, and a PCB-separate soldering fixture as described above. The soldering fixture is placed on the conveyor line, and the soldering mechanism is located below the conveyor line. This production line achieves greater flexibility and maintainability by using the PCB-separate soldering fixture. The quick-change mechanism for worn parts on the soldering fixture ensures continuous operation of the production line, reducing production interruptions caused by equipment maintenance, which effectively improves production efficiency.

[0046] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0047] Printed circuit boards (PCBs) are one of the core components of electronic devices. They carry electronic components and transmit electronic signals through circuit connections. With the rapid development of electronic technology, the application range of PCBs is becoming increasingly wide, from small electronic devices such as Bluetooth headsets and smartwatches to large equipment such as computers, communication equipment, and military / aerospace systems. Automated soldering is a crucial step in the PCB production process. The use of carriers is indispensable in automated soldering. Currently, the carrier body design commonly used in the market is a one-piece design. This design has significant problems in practical applications: because the carrier needs to be in direct contact with the soldering equipment during operation, friction is inevitable. If the carrier is made of a highly wear-resistant material, although wear can be reduced, it may damage the soldering equipment, thus affecting the normal service life and performance of the equipment. On the other hand, if the wear resistance of the carrier is lower than that of the soldering equipment, the carrier will show significant wear over a long period of friction. Because traditional carriers use a one-piece design, once a part wears out, the entire carrier needs to be replaced, which wastes materials and processing costs, and the replacement process is cumbersome and difficult to repair. In addition, frequent vehicle changes can affect production efficiency and increase the company's operating costs.

[0048] Based on this, this application provides a PCB detachable soldering fixture.

[0049] Example 1

[0050] like Figures 1-8 As shown, this embodiment provides a PCB detachable soldering fixture, including:

[0051] The base 1 has a placement position 11 for placing the PCB and a clamping member 3 for pressing the PCB. The clamping member 3 is used to stabilize the PCB during the soldering process, thereby ensuring that the PCB can be accurately soldered.

[0052] In practical applications, the structure of placement position 11 is adjusted to suit the PCB.

[0053] The base 1 is also provided with a support plate 2, which is used to support the base 1 on the welding equipment. The support plate 2 is detachably connected to the base 1.

[0054] In practical use, the clamping component 3 is used to fix the PCB during the welding process, ensuring the accuracy and stability of the PCB's position. The support plate 2 supports the base 1 on the welding equipment, and the support plate 2 can be detachably connected to the base 1. For example, the support plate 2 can be quickly removed from the base 1 using a mechanism such as screws or clips, so that it can be quickly replaced after the support plate 2 wears out, without having to replace the entire base 1. When the support plate 2 wears to a certain extent, it can simply be removed and replaced with a new support plate 2, and the fixture can be put back into normal use. The fixture design reduces the need for complete replacement due to wear, effectively utilizes resources, and reduces material waste. The quick-replacement design of the support plate 2 reduces production line downtime and improves production efficiency.

[0055] In this embodiment, two support plates 2 are provided on the base 1, and the two support plates 2 are symmetrically arranged on opposite sides of the base 1.

[0056] In this embodiment, by symmetrically arranging two support plates 2 on the base 1, the stability of the fixture is significantly improved, reducing the problem of fixture tilting or instability caused by wear of the support plates 2. Since the PCB is firmly fixed during the soldering process, the soldering quality is guaranteed, reducing soldering defects caused by carrier problems.

[0057] It should be noted that the support plate 2 in this application can be a long strip structure, and the structural shape of the support plate 2 can also be adjusted as needed.

[0058] Example 2

[0059] This embodiment is an improvement on embodiment 1.

[0060] like Figures 1-8 As shown, in this embodiment, the base 1 is provided with a mounting groove 12, the support plate 2 is embedded in the mounting groove 12, and the support plate 2 is detachably connected to the base 1 by a locking member.

[0061] In this embodiment, the shape and size of the mounting groove 12 match the support plate 2 so that the support plate 2 can be precisely embedded therein. This design makes the installation of the support plate 2 easier and ensures the stability of the support plate 2 during the welding process, significantly improving the stability of the tooling and preventing welding errors caused by the movement of the support plate 2.

[0062] In a preferred embodiment, a notch is provided on one side of the mounting groove 12, and after the support plate 2 is embedded in the mounting groove 12, one side of the support plate 2 protrudes from the notch.

[0063] One side of the support plate 2 protrudes from the notch. During use, the protruding part of the support plate 2 connects with the welding equipment, providing stable support for the tooling. In actual use, the width of the protruding part of the support plate 2 is greater than 1 cm to ensure effective support for the entire tooling, thus ensuring the stability of the tooling during use and preventing welding errors caused by the movement of the support plate 2.

[0064] In practical applications, the mounting groove 12 and the support plate 2 are interference-fitted, allowing the support plate 2 to be easily embedded into the mounting groove 12. The distance between the sidewall of the mounting groove 12 and the sidewall of the support plate 2 is 1mm-2mm, a design that reduces loosening of the support plate 2 after installation. The sidewall of the mounting groove 12 is smooth and has a certain thickness to ensure that the support plate 2 receives sufficient support and protection after embedding. Furthermore, the depth design of the mounting groove 12 needs to ensure the stability of the support plate 2 after embedding, while avoiding excessive embedding that would make it difficult to remove or replace the support plate 2.

[0065] Example 3

[0066] This embodiment is an improvement on embodiment 1.

[0067] like Figures 1-8 As shown, in this embodiment, the locking component includes a bolt, the mounting groove 12 is provided with a threaded hole 121, the support plate 2 is provided with a through hole 21, and the bolt passes through the through hole 21 and is threadedly connected to the threaded hole 121.

[0068] This embodiment provides a specific implementation of the locking component, which is a bolt. The bolt is threadedly connected to the threaded hole 121, which is not only convenient and quick, but also ensures the installation stability of the support plate 2.

[0069] In another method, the support plate 2 and the mounting groove 12 can be fixed together by a snap-fit ​​connection. Specifically, the mounting groove 12 on the base 1 has a snap-fit ​​groove on its edge, and the support plate 2 has a corresponding snap-fit ​​protrusion. When the support plate 2 is inserted into the mounting groove 12, the snap-fit ​​protrusion and the snap-fit ​​groove engage to achieve a stable connection between the support plate 2 and the mounting groove. This snap-fit ​​connection method requires no additional tools and is simple and quick to operate.

[0070] The support plate 2 and the mounting groove 12 can also be fixed by a pin connection. Pin holes can be provided on both sides of the mounting groove 12, and corresponding pin grooves are provided on the support plate 2. After the support plate 2 is inserted into the mounting groove 12, the support plate 2 can be fixed by passing a pin through the pin hole and inserting it into the pin groove. The pin connection also has the advantages of simple structure and convenient operation.

[0071] The support plate 2 and the mounting groove 12 can also be fixed by a clamping device. The clamping device includes a clamping body and a movable clamping arm. After the support plate 2 is inserted into the mounting groove 12, the clamping arm is moved towards the clamping body by operating it, and the support plate 2 is tightly clamped by spring force. The quick clamping device has the advantages of simple operation, large clamping force and adjustable clamping force.

[0072] Example 4

[0073] This embodiment is an improvement on embodiment 1.

[0074] like Figures 1-8 As shown, in this embodiment, the clamping member 3 includes a pressure plate 31 and a connecting arm 32. The connecting arm 32 is hinged to the base 1. The pressure plate 31 is disposed on one side of the connecting arm 32, and a clamping surface is provided on the pressure plate 31.

[0075] The connecting arm 32 is hinged to the base 1, allowing the pressure plate 31 to rotate around the hinge point. The pressure plate 31 is located on one side of the connecting arm 32 and is used to directly contact the PCB and apply pressure to fix the PCB in position. The pressing surface on the pressure plate 31 contacts the PCB to ensure stable fixation of the PCB during soldering and to prevent displacement or vibration of the PCB during soldering.

[0076] The clamping surface is the part of the pressure plate 31 that directly contacts the PCB board. Therefore, the design of the clamping surface is crucial. It needs to ensure that the PCB board can be stably fixed during the soldering process, preventing displacement or vibration. In practical applications, the clamping surface can use suitable materials and textures to increase the friction between it and the PCB board, such as setting wavy stripes on the clamping surface.

[0077] In a preferred embodiment, a cushioning material, such as high-temperature resistant rubber, can be provided on the pressing surface to reduce damage to the PCB. Specifically, the high-temperature resistant rubber can be silicone rubber, fluororubber, or neoprene rubber.

[0078] In a preferred embodiment, a damping element may be provided at the hinge of the connecting arm 32 and the base 1. The damping element is used to maintain the position of the connecting arm 32, that is, when the pressure plate 31 is not subjected to external force, the connecting arm 32 can be suspended at the target position.

[0079] Example 5

[0080] This embodiment is an improvement on embodiment 1.

[0081] like Figures 1-8 As shown, in this embodiment, the pressure plate 31 is provided with a handle 311 and a positioning post 312, and the positioning post 312 is provided on one side of the handle 311.

[0082] The handle 311 allows the operator to easily operate the pressure plate 31. A positioning post 312 is provided on one side of the handle 311, providing additional stability and precision during operation to ensure that the pressure plate 31 does not shift when pressure is applied. During soldering, the operator can grip the handle 311 and operate the connecting arm 32 to bring the clamping surface of the pressure plate 31 into contact with the PCB and apply appropriate pressure to secure the PCB. The positioning post 312 ensures precise positioning of the pressure plate 31 during operation. After soldering is complete, the operator can lift the pressure plate 31 to release the PCB.

[0083] In practical applications, the handle 311 is ergonomically designed so that operators can grip it comfortably. For example, the handle 311 has a certain curvature or bend to conform to the natural shape of the human hand. The handle 311 can also adopt an anti-slip design, such as adding textures, grooves, or protrusions to the surface of the handle 311 to increase friction and prevent the hand from slipping.

[0084] Example 6

[0085] This embodiment is an improvement on embodiment 1.

[0086] like Figures 1-8 As shown, in this embodiment, a magnet 5 is also provided on the base 1, and the magnet 5 is disposed on the edge of the placement position 11.

[0087] The function of magnet 5 is to provide additional fixing force during the soldering process to prevent the PCB from shifting or vibrating. Magnet 5 is positioned at the edge of placement position 11, so that after the PCB is placed in place, the magnetic force attracts the edges of the PCB, enhancing its stability. The position and number of magnets 5 can be adjusted according to the size and shape of the PCB to achieve the best fixing effect. During the soldering process, the operator places the PCB on placement position 11, and magnet 5 automatically attracts the edges of the PCB, fixing it in place. The operator can then further secure the PCB using clamping device 3. After soldering is complete, the operator can release clamping device 3 and the magnetic force to remove the soldered PCB.

[0088] In practical applications, multiple magnets 5 can be mounted on the base 1. In another application, magnets 5 can also be used to attract the pressure plate 31, allowing the pressure plate 31 to hold the PCB in the mounting position. The pressure plate 31 can also be equipped with…

[0089] Example 7

[0090] This embodiment is an improvement on embodiment 1.

[0091] like Figures 1-8As shown, in this embodiment, a snap fastener 4 is also provided on the base 1, and the snap fastener 4 is provided on the edge of the placement position 11;

[0092] The buckle 4 includes a buckle body 41 and a rotating connector 43. The rotating connector 43 is pivotally connected to the base 1, and the buckle body 41 is fixedly connected to the rotating connector 43.

[0093] The rotating connector 43 is also provided with an elastic element 42, which is disposed between the rotating connector 43 and the buckle body 41.

[0094] The rotating connector 43 is pivotally connected to the base 1, allowing the snap fastener 4 to rotate around the rotating connector 43. The snap fastener body 41 is fixedly connected to the rotating connector 43 and is used to directly contact the PCB and apply pressure to fix the PCB's position. An elastic element 42 is disposed between the rotating connector 43 and the snap fastener body 41. The function of the elastic element 42 is to provide a restoring force when the snap fastener 4 applies pressure, ensuring that the snap fastener 4 can make tight contact with the PCB and guaranteeing the PCB's stable position. During the soldering process, the operator can operate the rotating connector 43 to rotate the snap fastener body 41 around the rotating connector 43 and apply pressure to the PCB. With the assistance of the elastic element 42, the PCB is firmly fixed. After soldering is completed, the operator rotates the rotating connector 43 again to release the PCB.

[0095] In practical applications, the shape of the buckle 41 can be adjusted as needed, and the buckle 41 can be made of rubber.

[0096] Example 8

[0097] like Figures 1-11 As shown, this embodiment provides a PCB welding production line, including a transmission line 100, a welding mechanism 200, and a PCB-separated welding fixture as described above. The welding fixture is placed on the transmission line 100, and the welding mechanism 200 is disposed below the transmission line 100.

[0098] In this production line, conveyor line 100 transports the soldering fixture containing the PCB to the soldering position. Soldering mechanism 200, located below conveyor line 100, performs the soldering operation. As the PCB moves to the soldering position via conveyor line 100, soldering mechanism 200 descends above the PCB and performs the soldering operation. During this process, the clamping element 3 of the PCB-separable soldering fixture firmly secures the PCB in place, ensuring soldering accuracy.

[0099] The working process of the PCB soldering production line in this embodiment is as follows:

[0100] First, the PCB is placed on a soldering fixture, which is then neatly positioned on the transmission line 100. In this embodiment, the transmission line 100 can be implemented using two opposing transmission belts, with the soldering fixture placed between the two belts. The PCB is secured by clamping elements 3 (such as pressure plates 31) on the fixture.

[0101] Once the welding fixture is ready, the conveyor line 100 starts. The conveyor line 100 employs an advanced automated control system to precisely transport the welding fixture to the welding position. When the welding fixture is delivered to the welding position, the welding mechanism 200 starts to perform welding operations on the PCB. During the welding process, the clamping components 3 on the welding fixture ensure that the PCB does not move during welding, thus guaranteeing the stability and accuracy of the welding.

[0102] After the welding operation is completed, the welding mechanism 200 resets, while the conveyor line 100 continues to transport the welding fixture to the next processing position. Operators can then inspect and test the welded PCB at this subsequent location to ensure its quality and performance meet requirements. Defective or substandard PCBs can be reworked or scrapped; while qualified PCBs can proceed with subsequent assembly and testing.

[0103] In practical applications, the welding mechanism 200 includes a welding body, on which a welding head, a positioning and guiding system, a temperature control system, and a gas protection system are installed. The welding head can employ various welding technologies, such as hot air welding, laser welding, and ultrasonic welding, depending on the welding requirements and the characteristics of the PCB board. The positioning and guiding system includes servo motors, precision guide rails, and linear sensors to achieve precise positioning and movement of the welding head in three-dimensional space. Precise temperature control of the welding head is required during the welding process to ensure welding quality and PCB board integrity. The temperature control system includes heating elements, a cooling system, temperature sensors, and feedback control algorithms to achieve real-time monitoring and adjustment of the welding temperature. The gas protection system includes a gas supply device, gas nozzles, and flow control valves. The gas protection system uses inert gas to protect the welding area from oxidation by air.

[0104] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0105] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
