Description

Technical Field

[0001] This utility model relates to the technical field of stud tightening devices, and more specifically, it relates to a blow-type tightening device for wiring studs. Background Technology

[0002] As a core component of electronic devices, the assembly accuracy and reliability of printed circuit boards (PCBs) directly affect the performance of the devices. During PCB assembly, studs, as common connecting elements used to secure wires or connectors, are of paramount importance in their installation quality.

[0003] Traditional wiring studs typically feature an external thread on one end and an internal thread on the other. While this design facilitates connection, it also presents significant challenges for automated installation. Due to the nature of threaded connections, ordinary bolt tightening devices are difficult to apply directly to the installation of such studs, especially when aligning them. If the studs are tilted, the installation difficulty is further increased.

[0004] Currently, the most common way to install these studs on the market is by manually tightening them. This method is labor-intensive and inefficient. Another method involves using a tightening device to pick up a stud from a feeding box, then moving it over the workpiece to tighten it. This method requires the equipment to move back and forth, resulting in a long travel distance and similarly low efficiency.

[0005] Therefore, a blow-type tightening device for wiring studs is proposed to solve the above problems and achieve a small movement range and more efficient cycle time. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a blow-type tightening device for wiring studs with a small movement range, higher cycle time, and improved production efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A blow-type tightening device for wiring studs includes an up-and-down pushing mechanism, the output end of which is connected to a rotary drive mechanism, and the output end of the rotary drive mechanism is connected to an adsorption tightening assembly. The adsorption tightening assembly is disposed at the bottom end of the rotary drive mechanism, and a gate control mechanism is disposed at the bottom end of the adsorption tightening assembly. The gate control mechanism is fixedly connected to the up-and-down pushing mechanism, and a blow-through pipe is connected to one side of the gate control mechanism. The adsorption tightening assembly includes a tightening bolt portion, which is disposed on the extension line of the axial direction of the output end of the rotary drive mechanism, and a positioning part is disposed at the center of the tightening bolt portion.

[0009] By adopting the above technical solution, the screw-in part, the positioning part, and the air extraction part work together to perform coarse positioning and adsorption of the wiring stud, avoiding the waste of time for precise alignment, improving the process cycle and work efficiency.

[0010] The present invention is further configured such that: the adsorption tightening assembly also includes a vacuum suction tube mounting base, the vacuum suction tube mounting base is fixedly connected to the output end of the up-down pushing mechanism, the vacuum suction tube mounting base is rotatably connected to a rotating shaft part along the axis, and the rotating shaft part is coaxially arranged with the output end of the rotation drive mechanism.

[0011] The present invention is further configured such that: the rotating shaft part includes a rotating shaft rod body, the bottom of the rotating shaft rod body is provided with a first ventilation groove along the axis, and the rotating shaft rod body is provided with a plurality of air inlets around the first ventilation groove, and the plurality of air inlets are connected to the first ventilation groove.

[0012] The present invention is further configured such that: an extension tube is fixedly connected to the bottom of the first ventilation groove, the extension tube has a hollow structure, and the bolt part is provided on the side of the extension tube away from the rotating shaft.

[0013] The present invention is further configured such that: the bolt part includes a connecting pipe, a tightening pipe is provided on the side of the connecting pipe away from the rotating shaft part, a second vent groove is provided through the center of the connecting pipe and the tightening pipe, and a spline groove is provided on the side of the tightening pipe away from the connecting pipe.

[0014] The present invention is further configured such that: the positioning part includes a fixing post, the fixing post is disposed at the top of the bolt part, and an air guide post is disposed on the side of the fixing post away from the rotation drive mechanism, and the air guide post is inserted into the bolt part.

[0015] The present invention is further configured such that: multiple sets of air guide grooves are formed around the axis on the outer wall of the air guide column, the multiple sets of air guide grooves are arranged through the fixed column, a guide column is provided on the side of the air guide column away from the fixed column, and the guide column has a conical surface on the side away from the air guide column.

[0016] By adopting the above technical solution, the conical surface of the guide post provides guidance for the wiring stud. Even if the wiring stud is tilted when it enters the door control mechanism, it can be corrected by the guide post, avoiding the tilt of the wiring stud from affecting the subsequent generation of the cycle, improving the stability of the device, and without increasing the cost too much.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. By coarsely positioning and adsorbing the wiring studs through the screw-in part, positioning part and air extraction, the time wasted on precise alignment is avoided, the process cycle is improved and the work efficiency is increased.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0034] Example 1, please refer to Figure 1-7 The present invention provides the following technical solution:

[0035] Specifically, it refers to a blow-type tightening device for wiring studs, see [reference]. Figure 1-2 The device includes a vertical pushing mechanism 1, which has a telescopic cylinder, a guide rail, and a slider. The slider is the output end of the vertical pushing mechanism 1. By controlling the operation of the telescopic cylinder, the slider slides up and down. The output end of the vertical pushing mechanism 1 is connected to a rotary drive mechanism 2, which controls the rotation of its shaft. The output end of the rotary drive mechanism 2 is connected to an adsorption tightening assembly 3, i.e., the shaft is connected to the adsorption tightening assembly 3. By rotating, the wiring stud can be tightened. In addition, the vertical pushing mechanism 1 can also drive the adsorption tightening assembly 3 to move up and down. The adsorption tightening assembly 3 is located at the bottom of the rotary drive mechanism 2. A gate control mechanism 4 is located at the bottom of the adsorption tightening assembly 3. The gate control mechanism 4 has a gate control claw that can be used to prevent the wiring stud from falling. When it is necessary to tighten the wiring stud, the gate control claw can be opened to extend the adsorption tightening assembly 3 to tighten the workpiece. The gate control mechanism 4 is fixedly connected to the vertical pushing mechanism 1. A blow pipe 5 is connected to one side of the gate control mechanism 4. The blow pipe 5 is used to transport the wiring stud into the interior of the gate control mechanism 4.

[0036] See Figure 3-7The adsorption tightening assembly 3 includes a vacuum suction tube mounting base 31, which is fixedly connected to the output end of the up-down pushing mechanism 1. A rotating shaft 32 is rotatably connected to the vacuum suction tube mounting base 31 along its axis, and the rotating shaft 32 is coaxially arranged with the output end of the rotary drive mechanism 2. The rotating shaft 32 includes a rotating shaft rod body 321, with a first ventilation groove 322 formed at the bottom of the rotating shaft rod body 321 along its axis. Multiple sets of air inlets 323 are formed around the first ventilation groove 322, and these air inlets 323 communicate with the first ventilation groove 322. An extension tube 33 is fixedly connected to the bottom of the first venting groove 322. The extension tube 33 has a hollow structure and is coaxially arranged with the rotating shaft 32. A screw bolt 34 is provided on the side of the extension tube 33 away from the rotating shaft 32. The screw bolt 34 is coaxially arranged with the extension tube 33. The screw bolt 34 includes a connecting tube 341. A tightening tube 342 is provided on the side of the connecting tube 341 away from the rotating shaft 32. A second venting groove 343 is opened through the center of the connecting tube 341 and the tightening tube 342. A spline groove 344 is opened on the side of the tightening tube 342 away from the connecting tube 341. A positioning part 35 is provided at the center of the bolt part 34. The positioning part 35 includes a fixing post 351. A guide post 352 is provided on the side of the fixing post 351 away from the rotating shaft part 32. The guide post 352 is inserted into the second vent groove 343. Multiple sets of guide grooves 353 are opened around the axis on the outer wall of the guide post 352. The multiple sets of guide grooves 353 are provided through the fixing post 351. A guide post 354 is provided on the side of the guide post 352 away from the fixing post 351. The guide post 354 has a conical surface on the side away from the guide post 352.

[0037] Specifically, the conical surface of the guide post 354 guides the terminal screw. Even if the terminal screw enters the gate control mechanism 4 at an angle, the guide post 354 can correct it, preventing the tilt of the terminal screw from affecting the subsequent cycle time, improving the stability of the device, and without increasing costs excessively. Air is drawn upwards through the gap between the second vent groove 343 and the air guide groove 353, allowing the terminal screw to be attracted. Even if the outer wall of the terminal screw is not perfectly aligned with the spline groove 344, it can still be attracted. During tightening, the misaligned terminal screw will automatically slide into the spline groove 344 after rotating it a certain angle, without affecting its subsequent insertion into the workpiece. This coarse positioning avoids the time wasted on precise alignment, improves the process cycle time, and increases work efficiency.

[0038] In use, the wiring stud is blown into the door control mechanism 4 through the blow pipe 5 and falls onto the door control gripper at the bottom of the door control mechanism 4. The telescopic cylinder of the up-and-down pushing mechanism 1 drives the slider to move downward. The rotation drive mechanism 2 and the suction tightening assembly 3 follow the slider downward. At this time, if the wiring stud is in an inclined state, the conical surface of the guide post 354 contacts the inner wall of the wiring stud. As it continues to descend, it straightens the wiring stud, and the conical surface of the guide post 354 is fully inserted into the interior of the wiring stud. The vacuum suction tube mounting seat 31 is controlled by the external air circuit to draw internal air from the top of the wiring stud through the second air groove 343 and the air guide groove 3. 53. The inner wall of the extended tube 33, the first ventilation groove 322, and the air inlet 323 are finally drawn away from the vacuum suction tube mounting base 31, thus creating a negative pressure state inside, which adsorbs the wiring stud. When a signal is received from the outside that the bolt needs to be tightened, the gate control jaw of the gate control mechanism 4 opens, driving the telescopic cylinder of the up-down pushing mechanism 1 to continue to move downward. The extended tube 33 extends out of the gate control jaw of the gate control mechanism 4. When it reaches above the workpiece, it drives the rotary drive mechanism 2, causing the rotating shaft of the rotary drive mechanism 2 to rotate the rotating shaft part 32, thereby driving the extended tube 33 and the bolt tightening part 34 to rotate, so that the wiring stud is screwed into the workpiece and locked.

[0039] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
