Description

Technical Field

[0001] This utility model relates to the field of automatic welding equipment technology, and in particular to an automatic welding device for PCBA production. Background Technology

[0002] Automatic welding equipment is a type of equipment used in PCBA production to automatically weld electronic components onto circuit boards. Automatic welding devices mainly improve production efficiency, reduce manual operation, and ensure the quality and consistency of welding.

[0003] Utility model CN218785268U discloses an automatic welding device for transistor height-limited PCBA boards. The key technical points are: it includes an automatic welding device comprising a workbench, a control console, a placement trough, an automatic welding machine, a first conveyor belt, a mounting plate, an electric push rod, a push plate, a second conveyor belt, a mounting frame, an activated carbon plate, a placement plate, an electric telescopic rod, and an air intake fan. This automatic welding device for transistor height-limited PCBA boards, by installing the first and second conveyor belts, the electric telescopic rod, the electric push rod, the push plate, and the placement plate, allows the PCBA board to be fed into the placement trough via the first conveyor belt when welding is required, causing it to fall onto the top surface of the placement plate for automatic welding. After welding, the electric telescopic rod drives the placement plate to rise, and then the electric push rod drives the push plate to push the PCBA board from the top surface of the placement plate onto the second conveyor belt for unloading.

[0004] Regarding the aforementioned issues, the following technical defects exist: Automatic soldering equipment in PCBA production is a machine used to solder electronic components onto PCBA boards. These devices are primarily used to improve production efficiency and soldering quality, and reduce human error. During soldering, the PCBA board can be directly placed on the support base of the automatic soldering equipment, and the soldering head can then be used to solder the PCBA board. After soldering, the PCBA board can be removed from the support base. However, it has been found that the placement of the PCBA board is entirely done manually. Manual placement introduces errors, which affects the soldering effect of the automatic soldering equipment on the PCBA board. Furthermore, manual placement is slow, affecting the overall soldering speed of the PCBA board.

[0005] Therefore, it is necessary to provide a new type of automated welding device for PCBA production to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies where the placement of PCBA boards is entirely done manually. Manual placement introduces errors, which affects the welding effect of automated welding equipment on the PCBA boards. Furthermore, manual placement is slow, impacting the overall welding speed of the PCBA boards.

[0007] To solve the above-mentioned technical problems, this utility model provides an automatic welding device for PCBA production, comprising: an automatic welding equipment, a support base mounted on the upper surface of the automatic welding equipment, a welding head mounted on the side of the automatic welding equipment near the support base, an adjustment device provided on the side of the automatic welding equipment near the support base, the adjustment device including a connecting block, the connecting block being fixedly connected to one side of the automatic welding equipment, a motor being fixedly connected to one side of the connecting block, a rotating rod being fixedly connected to the output end of the motor, connecting rings being threaded to both ends of the arc surface of the rotating rod, a connecting rod being fixedly connected to one end of the arc surface of the connecting ring, a moving platform being fixedly connected to one end of the arc surface of the connecting rod away from the connecting ring, two adjustment blocks being fixedly connected to the side of the moving platform away from the connecting rod, and a common guide rod slidingly penetrating the inner wall of the four adjustment blocks, the arc surface of the guide rod being fixedly connected to one side of the automatic welding equipment.

[0008] The aforementioned components achieve the following effects: Automatic soldering equipment in PCBA production is a machine used to solder electronic components onto PCBA boards. These devices primarily improve production efficiency and soldering quality, reducing human error. During soldering, the PCBA board can be directly placed on the support of the automatic soldering equipment, and the soldering head can then be used to solder the PCBA board. After soldering, the PCBA board can be removed from the support. However, it has been found that the placement of the PCBA board is entirely manual, which introduces errors and affects the soldering effect of the automatic soldering equipment. Furthermore, manual placement is slow, impacting the soldering speed. Therefore, an adjustment device can be used to replace manual placement of the PCBA board, thereby improving the accuracy of placement and increasing soldering efficiency.

[0009] Preferably, an auxiliary ring is slidably connected to one end of the arc surface of the guide rod, and a spring is sleeved on one end of the arc surface of the guide rod, with the two ends of the spring being fixedly connected to the auxiliary ring and the guide rod, respectively.

[0010] The effect achieved by the above components is that when the adjusting block slides on the guide rod, the auxiliary ring installed on the spring can prevent the adjusting block from sliding and abutting against one end of the arc surface of the guide rod. Thus, under the action of the auxiliary ring, the adjusting block and the guide rod can be prevented from abutting and being damaged.

[0011] Preferably, guide grooves are provided on both sides of the inner wall of the four adjustment blocks, and the eight guide grooves are grouped into groups of four. The inner wall of each group of guide grooves is slidably connected to the same slider, and the two sliders are respectively fixedly connected to the two ends of the arc surface of the guide rod.

[0012] The effect achieved by the above components is that when the adjusting block slides along the direction of the guide rod, the slider can slide in the guide groove, thereby improving the stability of the adjusting block sliding on the guide rod.

[0013] Preferably, the guide rod is a titanium alloy rod.

[0014] The effect achieved by the above components is that the guide rod made of titanium alloy is less likely to react chemically with air, which also makes the guide rod less prone to corrosion even after long-term use, resulting in better performance.

[0015] Preferably, one end of the automatic welding equipment is provided with an auxiliary device, which includes two support arms. Both support arms are fixedly connected to the automatic welding equipment. Two support plates are fixedly connected to the sides of the two support arms that are far apart from each other. The inner walls of the support plates are rotatably connected to pulleys. One end of each support arm is slidably connected to a storage box. The inner walls of the storage box are fixedly connected to several partitions, which are evenly distributed on the storage box. Two fixing blocks are fixedly connected to both sides of the storage box. The inner walls of the two fixing blocks are rotatably connected to the same handle.

[0016] The effect achieved by the above components is that after the PCBA board has completed the soldering task, the PCBA board can be stored through the auxiliary device. Thus, the auxiliary device facilitates the centralized handling of the soldered PCBA board, improving the convenience of handling the PCBA board.

[0017] Preferably, a contact pad is fixedly connected to the side of the support arm near the storage box, and the cross-section of the contact pad is rectangular.

[0018] The effect achieved by the above components is that when the bottom of the storage box comes into contact with one side of the support arm, the contact pad installed on the support arm can prevent the storage box from directly contacting the support arm, thereby preventing wear and tear caused by contact between the storage box and the support arm.

[0019] Preferably, the partition has a material receiving groove on its side.

[0020] The effect achieved by the above components is as follows: after the partitions separate and store the PCBA boards, the material retrieval slots opened on the partitions make it convenient for workers to retrieve the materials when they need to be retrieved, thereby improving the efficiency of retrieving PCBA boards.

[0021] Compared with related technologies, the automatic welding device for PCBA production provided by this utility model has the following advantages:

[0022] By setting up an adjustment device, when PCBA boards need to be placed on automatic welding equipment for welding processing, the adjustment device can replace the manual placement method. The adjustment device can improve the accuracy of PCBA board placement, increase placement speed, and improve production quality.

[0023] By setting up auxiliary devices, PCBA boards can be temporarily stored after soldering. Once a certain number have been stored, the soldered PCBA boards can be moved in a centralized manner. The auxiliary devices can improve the efficiency and speed of moving PCBA boards. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0034] Please see Figures 1 to 7 The present invention provides an automatic welding device for PCBA production, comprising: an automatic welding device 1, a support base 5 mounted on the upper surface of the automatic welding device 1, a welding head 4 mounted on the side of the automatic welding device 1 near the support base 5, an adjustment device 2 provided on the side of the automatic welding device 1 near the support base 5, and an auxiliary device 3 provided at one end of the automatic welding device 1.

[0035] In the embodiments of this utility model, please refer to Figures 2 to 5The adjusting device 2 includes a connecting block 201, which is fixedly connected to one side of the automatic welding equipment 1. A motor 202 is fixedly connected to one side of the connecting block 201. A rotating rod 203 is fixedly connected to the output end of the motor 202. Both ends of the arc surface of the rotating rod 203 are threaded with connecting rings 204. A connecting rod 205 is fixedly connected to one end of the arc surface of the connecting ring 204. A moving platform 206 is fixedly connected to the end of the connecting rod 205 away from the arc surface of the connecting ring 204. Two adjusting blocks 207 are fixedly connected to the side of the moving platform 206 away from the connecting rod 205. A common guide rod 208 slides through the inner wall of the four adjusting blocks 207. One end of the arc surface of the guide rod 208 is fixedly connected to one side of the automatic welding equipment 1. The automatic soldering equipment 1 in PCBA production is a machine used to solder electronic components onto PCBA boards. These devices are mainly used to improve production efficiency and soldering quality, and reduce human error. During soldering, the PCBA board can be directly placed on the support base 5 of the automatic soldering equipment 1, and the soldering head 4 can then be used to solder the PCBA board. After soldering, the PCBA board can be removed from the support base 5. However, it was found that the placement of the PCBA board is entirely done manually. Manual placement introduces errors, which affects the soldering effect of the automatic soldering equipment 1 on the PCBA board. Furthermore, manual placement is slow, which also affects the soldering speed of the PCBA board. Speed: At this time, the PCBA board can be placed manually by adjusting device 2. Adjusting device 2 improves the accuracy of PCBA board placement and increases welding efficiency. An auxiliary ring 212 is slidably connected to one end of the arc surface of guide rod 208. A spring 211 is fitted onto one end of the arc surface of guide rod 208. The two ends of spring 211 are fixedly connected to the auxiliary ring 212 and guide rod 208 respectively. When adjusting block 207 slides on guide rod 208, the auxiliary ring 212 installed on spring 211 prevents adjusting block 207 from sliding and abutting against the arc surface of guide rod 208. Therefore, under the action of auxiliary ring 212, damage from contact between adjusting block 207 and guide rod 208 is avoided. Four adjusting blocks 20... Guide grooves 209 are provided on both sides of the inner wall of the 7. The eight guide grooves 209 are divided into groups of four. The inner wall of each group of guide grooves 209 is slidably connected to the same slider 210. The two sliders 210 are fixedly connected to the two ends of the arc surface of the guide rod 208 respectively. When the adjusting block 207 slides along the direction of the guide rod 208, the slider 210 can slide in the guide groove 209. This improves the stability of the adjusting block 207 sliding on the guide rod 208. The guide rod 208 is a titanium alloy rod. The titanium alloy guide rod 208 is less likely to react chemically with air, which also makes the guide rod 208 less prone to corrosion even after long-term use, resulting in better performance.

[0036] In the embodiments of this utility model, please refer to Figure 6 and Figure 7 The auxiliary device 3 includes two support arms 31, both of which are fixedly connected to the automatic welding equipment 1. Two support plates 32 are fixedly connected to the sides of the two support arms 31 that are furthest from each other. A pulley 33 is rotatably connected to the inner wall of each support plate 32. A storage box 34 is slidably connected to one end of each support arm 31. Several partitions 35 are fixedly connected to the inner wall of the storage box 34, and these partitions are evenly distributed on the storage box 34. Two fixing blocks 36 are fixedly connected to both sides of the storage box 34, and a common handle 37 is rotatably connected to the inner wall of each fixing block 36. After the PCBA board has completed its welding task, it can be stored using the auxiliary device 3. This allows for convenient centralized handling of the completed PCBA boards. The welded PCBA boards are handled to improve the ease of handling. A contact pad 38 is fixedly connected to the side of the support arm 31 near the storage box 34. The contact pad 38 has a rectangular cross-section. When the bottom of the storage box 34 comes into contact with one side of the support arm 31, the contact pad 38 installed on the support arm 31 can prevent the storage box 34 from directly contacting the support arm 31. Thus, the contact pad 38 can prevent wear caused by contact between the storage box 34 and the support arm 31. A material retrieval slot 39 is opened on the side of the partition 35. After the partition 35 separates and stores the PCBA boards, the material retrieval slot 39 opened on the partition 35 can facilitate the workers to retrieve the materials when they need to be retrieved. The material retrieval slot 39 can improve the efficiency of retrieving PCBA boards.

[0037] The working principle of the automatic welding device for PCBA production provided by this utility model is as follows: The PCBA board is placed in the moving platform 206. At this time, the motor 202 installed on the connecting plate can be started. The movement of the motor 202 will drive the rotating rod 203 to rotate through the output end. The rotation of the rotating rod 203 will drive the connecting ring 204 and the connecting rod 205 to move. The moving platform 206 will move together with the connecting rod 205. The movement of the moving platform 206 will drive the adjusting block 207 to slide on the guide rod 208. At this time, the moving platform 206 can move on the automatic welding equipment 1, thus completing the placement of the PCBA board.

[0038] Using the handle 37 installed on the fixing block 36, the storage box 34 can be lifted up. The bottom of the lifted storage box 34 is placed on the two support arms 31. The pulleys 33 installed on the support plate 32 can contact the two sides of the storage box 34, guiding the storage box 34 to contact the support arms 31. When the bottom of the storage box 34 contacts the support arms 31, the storage box 34 can be temporarily placed on one side of the automatic welding equipment 1. The PCBA boards can be separated and stored by the partition 35 installed inside the storage box 34.

[0039] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
