Description

Technical Field

[0001] This invention relates to the field of welding fixture technology, and in particular to an online measuring device for the elasticity of pressure bars. Background Technology

[0002] Currently, for flexible printed circuit boards (FPCBs) used in consumer electronics, some employ SMT (Surface Mount Technology) to mount various components onto the FPCB surface. After printing and mounting the components on the FPCB, reflow soldering is typically required to secure the components. Furthermore, during reflow soldering, clamping devices are used to firmly hold the components on the FPCB to prevent soldering defects.

[0003] In traditional technologies, some clamping strips use spring-loaded pressure heads to press components on flexible circuit boards. However, during use on the circuit board production line, the spring force of these spring-loaded clamping strips may change, leading to poor welding. Therefore, it is necessary to test the spring force of the clamping strips. Furthermore, in traditional technologies, clamping strips are sometimes used repeatedly on the circuit board production line. When testing the clamping strips, the circuit board production line must be paused, impacting production efficiency. Summary of the Invention

[0004] This invention provides an online measuring device for the elasticity of pressure strips, which can solve the technical problem that changes in the elasticity of pressure strip clamps using spring pressure heads in traditional technology can lead to poor welding, and that testing the pressure strip clamps on the production line requires stopping the production line, which affects production efficiency.

[0018] Optionally, the pressure head elasticity detection structure includes a detection base plate disposed on the frame, a base plate connection structure disposed on the detection base plate, and an elasticity detection sensor structure disposed on the detection base plate; the detection base plate is disposed vertically and vertically corresponding to the loading gripper mechanism and the unloading gripper mechanism, and the base plate connection structure is used to achieve a detachable connection with the pressure bar clamp.

[0019] The elastic force detection sensor structure includes multiple pressure sensors disposed on the detection substrate. The multiple pressure sensors are used to correspond one-to-one with multiple spring pressure heads on the pressure bar clamp to detect its elastic force.

[0020] Optionally, the pressure bar elasticity online measuring device includes a defective product storage mechanism disposed on the frame, the defective product storage mechanism being located below the pressure head elasticity detection structure;

[0021] The defective product storage mechanism includes a defective product conveying structure mounted on the frame, a defective product storage bin protruding above the defective product conveying structure, and a defective product lifting structure mounted on the frame.

[0027] The beneficial effects of the technical solution provided by this invention include:

[0028] When clamping printed components on a circuit board using a clamping strip, the spring force of the clamping strip's spring head can be tested online using an online clamping strip force measuring device. If the test is qualified, the qualified clamping strip can be immediately transported to the circuit board to be clamped, so that the clamping strip clamps the components on the circuit board for welding and fixing. If a defective clamping strip is detected, it can be immediately removed from the production line to prevent it from flowing into the production line and affecting the welding quality of the components on the circuit board. In this way, during the use of spring-loaded clamping strips on the circuit board production line, the spring force of the clamping strips can be detected online before or after each clamping and fixing of components on the circuit board. This allows for the timely detection and removal of unqualified clamping strips from the production line, ensuring that unqualified clamping strips are not used on the production line. This guarantees the welding quality of components on the circuit board and also ensures the operating efficiency of the production line.

[0029] Specifically, the feeding lifting and conveying structure of the pressing strip feeding mechanism at the feeding station can be connected to an external pressing strip conveying mechanism to receive the pressing strip clamps conveyed by the external pressing strip conveying mechanism and transport them to a position near the pressing strip elasticity detection mechanism. Then, the pressing strip clamps on the feeding lifting and conveying structure can be gripped by the feeding claw mechanism and transferred to the pressing head elasticity detection structure of the pressing strip elasticity detection mechanism. The pressing strip clamps are then installed on the pressing head elasticity detection structure, which can detect the elasticity of the spring head of the pressing strip clamp connected to it. The elasticity detection of the pressing strip clamps is completed at the pressing head elasticity detection structure. Subsequently, the pressing strip clamp on the pressing head elasticity detection structure can be disassembled and gripped by the pressing strip unloading mechanism, separating the pressing strip clamp from the pressing head elasticity detection structure. Then, the pressing strip clamp can be moved to the unloading lifting conveyor structure at the unloading station by the unloading clamp mechanism. When the pressing strip clamp is detected as a qualified product, it can be conveyed to the external pressing strip receiving mechanism by the unloading lifting conveyor structure, so that the pressing strip clamp can continue to be used on the circuit board production line. When the pressing strip clamp is detected as a defective product, it can be conveyed off the line by the unloading lifting conveyor structure, so that it is no longer used on the circuit board production line.

Detailed Implementation

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] like Figures 1 to 3As shown, this invention proposes an online pressure strip elasticity measuring device 10, including a frame 100, and a pressure strip feeding mechanism 200, a pressure strip elasticity detection mechanism 300, and a pressure strip unloading mechanism 400 sequentially arranged on the frame 100. Furthermore, the pressure strip feeding mechanism 200 and the pressure strip unloading mechanism 400 are connected to a circuit board production line. The pressure strip feeding mechanism 200 can pick up pressure strip clamps 20 from the circuit board production line, the pressure strip elasticity detection mechanism 300 can detect the elasticity of the pressure strip clamps 20 taken from the circuit board production line, and the pressure strip unloading mechanism 400 can remove unqualified pressure strip clamps 20 from the line or transport qualified pressure strip clamps 20 back to the circuit board production line for continued use, thereby realizing online detection of the pressure strip clamps 20.

[0047] Specifically, the frame 100 may be sequentially provided with a loading station, an inspection station, and an unloading station. Furthermore, the pressing strip loading mechanism 200 may include a loading lifting and conveying structure 202 located at the loading station of the frame 100, and a loading gripper mechanism 204 located on the frame 100 and above the loading lifting and conveying structure 202. The loading lifting and conveying structure 202 is used to interface with an external pressing strip conveying mechanism on the circuit board production line. Moreover, the pressing strip elasticity detection mechanism 300 may include a pressing head elasticity detection structure 310 located at the inspection station of the frame 100. The pressing head elasticity detection structure 310 is used to interface with the pressing strip clamp 20 and detect the elasticity of the pressing head on the pressing strip clamp 20. The loading gripper mechanism 204 is movably positioned between the loading station and the inspection station. Furthermore, the pressing strip unloading mechanism 400 may include an unloading lifting and conveying structure 402 located at the unloading station of the frame 100, and an unloading gripper mechanism 404 located on the frame 100 and above the unloading lifting and conveying structure 402. The unloading lifting and conveying structure 402 is used to dock with an external pressing strip receiving mechanism, and the unloading gripper mechanism 404 is movably located between the detection station and the unloading station.

[0048] When clamping printed components on a circuit board using the clamping strip 20, the spring force of the spring head of the clamping strip 20 can be tested online using the online clamping strip spring force measuring device 10. If the test is qualified, the qualified clamping strip 20 can be immediately transported to the circuit board to be clamped, so that the clamping strip 20 can clamp the components on the circuit board to facilitate the soldering and fixing of the components on the circuit board. If an unqualified clamping strip 20 is detected, the unqualified clamping strip 20 can be immediately removed from the production line to prevent the unqualified clamping strip 20 from flowing into the production line and affecting the soldering quality of the components on the circuit board. In this way, during the use of the spring clamp 20 with spring head on the circuit board production line, the spring force of the spring head of the clamp 20 can be detected online before or after each clamping and fixing of the components on the circuit board by the clamp 20 (or within a preset number of times or within a preset time period). This allows for the timely detection and removal of unqualified clamps 20 from the production line, ensuring that unqualified clamps 20 are not used on the production line. This guarantees the welding quality of the components on the circuit board and also ensures the operating efficiency of the production line.

[0049] Specifically, the pressing strip feeding mechanism 200 at the feeding station can connect with the external pressing strip conveying mechanism via its feeding lifting and conveying structure 202. This allows the pressing strip clamp 20, conveyed from the external conveying mechanism, to be received and transported to a position near the pressing strip elasticity detection mechanism 300. Then, the feeding gripper mechanism 200 can grasp the pressing strip clamp 20 on the feeding lifting and conveying structure 202 and transfer it to the pressing head elasticity detection structure 310 of the pressing strip elasticity detection mechanism 300. The feeding gripper mechanism 200 then installs the pressing strip clamp 20 onto the pressing head elasticity detection structure 310, which can detect the elasticity of the spring head of the pressing strip clamp 20 connected to it. After the pressing head elasticity detection structure 310 completes the detection of the elasticity of the pressing strip clamp 20... After inspection, the pressing strip clamp 20 on the pressing head elasticity detection structure 310 can be disassembled and gripped by the pressing strip unloading mechanism 404 of the pressing strip unloading mechanism 400, so that the pressing strip clamp 20 is separated from the pressing head elasticity detection structure 310. Then, the pressing strip clamp 20 can be moved to the unloading lifting and conveying structure 402 at the unloading station by the unloading clamping mechanism 404. When the pressing strip clamp 20 is detected as a qualified product, it can be conveyed to the external pressing strip receiving mechanism by the unloading lifting and conveying structure 402, so that the pressing strip clamp 20 can continue to be used on the circuit board production line. When the pressing strip clamp 20 is detected as a defective product, it can be conveyed off the line by the unloading lifting and conveying structure 402, so that it is no longer used on the circuit board production line.

[0050] Furthermore, such as Figures 3 to 6As shown, the feeding lifting and conveying structure 202 of the pressing strip feeding mechanism 200 may include a feeding lifting frame structure 210 mounted on the frame 100, and a feeding conveyor belt structure 220 mounted on the feeding lifting frame structure 210. The feeding gripper mechanism 204 is vertically corresponding to the feeding conveyor belt structure 210 and the pressing head elasticity detection structure 310. The feeding lifting frame structure 210 can move the feeding conveyor belt structure 220 up and down, allowing the feeding conveyor belt structure 220 to dock with external pressing strip conveying mechanisms located at different heights, facilitating the receiving of the pressing strip clamp 20 conveyed by the external pressing strip conveying mechanism; it can also make the height of the feeding conveyor belt structure 220 correspond to the height of the pressing head elasticity detection structure 310 of the pressing strip elasticity detection mechanism 300, facilitating the transfer of the pressing strip clamp 20 on the feeding conveyor belt structure 220 to the pressing head elasticity detection structure 310 by the feeding gripper mechanism 204.

[0051] Furthermore, the loading lifting frame structure 210 may include a lifting support base 212 mounted on the frame 100, a seat lifting drive structure 214 connected to the lifting support base 212, and a lifting support top seat 216 connected to the seat lifting drive structure 214. The loading conveyor belt structure 220 may be mounted on top of the lifting support top seat 216. The seat lifting drive structure 214 can drive the lifting support top seat 216 to move up and down, thereby driving the loading conveyor belt structure 220 mounted on the lifting support top seat 216 to move up and down, so that the loading conveyor belt structure 220 can dock with the external pressure strip conveying mechanism at different height positions.

[0052] Furthermore, the seat lifting drive structure 214 may include a seat lifting motor 2142 located at the bottom of the lifting support top seat 216, and a screw and nut transmission structure 2144 connected to the output shaft of the seat lifting motor 2142. The screw and nut transmission structure 2144 is connected to the lifting support base 212. The seat lifting motor 2142 can drive the screw and nut transmission structure 2144 to work, causing the screw and nut transmission structure 2144 to drive the lifting support top seat 216 to move up and down. Moreover, the screw and nut transmission structure 2144 may include a drive screw connected to the output shaft of the seat lifting motor 2142, and a transmission nut threadedly connected to the drive screw. The transmission nut may be connected to or integrated with the lifting support base 212. In this way, the transmission nut and the lifting support base 212 can be fixed together on the frame 100. When the drive screw rotates under the drive of the seat lifting motor 2142, it will automatically rise or fall under the action of the transmission nut, thereby driving the lifting support top seat 216 to move up and down.

[0053] Alternatively, the seat lifting motor 2142 can be mounted on the lifting support base 212, and the screw-nut transmission structure 2144 can be connected to the lifting support top seat 216. This allows the drive screw of the screw-nut transmission structure 2144 to be connected to the output shaft of the seat lifting motor 2142, while the transmission nut of the screw-nut transmission structure 2144 can be connected to the lifting support top seat 216, directly driving the lifting support top seat 216 to move up and down. Furthermore, the aforementioned screw-nut transmission structure 2144 can be replaced with a gear and rack transmission structure or other similar linear transmission structures. Additionally, the seat lifting drive structure 214 can include multiple seat guide rods 218 disposed between the lifting support top seat 216 and the lifting support base 212. One end of each guide rod 218 can be fixed to the bottom of the lifting support top seat 216, and the other end can movably pass through the lifting support base 212, providing alignment, guidance, and support during the lifting movement of the lifting support top seat 216. In addition, the seat lifting drive structure 214 may also include a vertical support guide rail 219 provided on the frame 100, and the lifting support top seat 216 can be slidably provided on the vertical support guide rail 219, so that the lifting support top seat 216 can move more stably.

[0054] Furthermore, the feeding conveyor belt structure 220 may include a conveyor belt frame 222 located on top of the lifting support top seat 216 of the feeding lifting frame structure 210, a conveyor belt structure 224 located on the conveyor belt frame 222, and a conveyor belt adjustment structure 226 connected to the conveyor belt frame 222. When the feeding conveyor belt structure 220 is aligned with the external pressing strip conveying mechanism by the lifting action of the feeding lifting frame structure 210, the pressing strip clamp 20 conveyed by the external pressing strip conveying mechanism can be received and conveyed via the conveyor belt structure 224 located on the conveyor belt frame 222, and conveyed to the pressing head elasticity detection structure 310 at the detection station. Moreover, the conveyor belt frame 222 can be adjusted via the conveyor belt adjustment structure 310 to change its width to accommodate pressing strip clamps 20 of different sizes.

[0055] Specifically, the conveyor belt frame 222 may include two conveyor support frames 2222 arranged side-by-side on the top of the lifting support top seat 216 of the loading lifting frame structure 210; and the conveyor belt structure 224 may include a conveyor belt 2242 respectively provided on the two conveyor support frames 2222, and a conveyor drive structure 2244 correspondingly connected to each conveyor belt 2242. The pressing strip clamp 20 conveyed by the external pressing strip conveying mechanism will automatically fall onto the conveyor belts 2242 of the two conveyor support frames 2222 of the conveyor belt frame 222. The conveyor drive structure 2244 can drive the transmission belt 2242 to rotate, thereby conveying the pressing strip clamp 20 on the two conveyor belts 2242. Further, the conveyor drive structure 2244 may include a conveyor drive motor provided on the conveyor support frame 2222, and a pulley drive structure connected to the conveyor drive motor. The pulley drive structure can be connected to the conveyor belt 2242. Furthermore, in this embodiment, a pulley drive wheel can be provided at the output end of the conveyor drive motor, and a pulley driven wheel can be provided at each end of the side of the conveyor support frame 2222. The conveyor belt 2242 is directly sleeved on the pulley drive wheel and the two pulley driven wheels to drive the conveyor belt 2242. Moreover, the conveyor drive structure 2244 may include two pulley tensioning wheels provided on the conveyor support frame 2222. The two pulley tensioning wheels are located on both sides of the pulley drive wheel and on the outside of the conveyor belt 2242 to tension the conveyor belt 2242.

[0056] Furthermore, one of the two conveyor support frames 2222 is movably mounted on the top of the lifting support top seat 216 of the loading lifting frame structure 210, and the other is fixedly mounted on the top of the lifting support top seat 216 of the loading lifting frame structure 210. Moreover, the conveyor belt adjustment structure 226 can be connected to the movably mounted conveyor support frame 2222. The movably mounted conveyor support frame 2222 can be moved away from or closer to the other fixedly mounted conveyor support frame 2222 through the conveyor belt adjustment structure 226, so as to increase or decrease the distance between the two conveyor support frames 2222. This allows the loading conveyor belt structure 220 to adapt to and convey pressure strip clamps 20 of different sizes.

[0057] Specifically, the conveyor belt adjustment structure 226 may include an adjustment drive structure 2262 disposed on top of the lifting support top seat 216 of the loading lifting frame structure 210, and a linear transmission structure 2264 connected to the adjustment drive structure 2262. The linear transmission structure 2264 is connected to a movably disposed conveyor support frame 2222. The adjustment drive structure 2262 can drive the linear transmission structure 2264 to operate, thereby driving the conveyor support frame 2222 connected to the linear transmission structure 2264 to move, so as to change the distance between the two conveyor support frames 2222.

[0058] Furthermore, the conveyor belt adjustment structure 226 may include an adjustment bracket 2261 disposed on the top of the lifting support top seat 216 of the loading lifting frame structure 210, and an adjustment drive structure 2262 may be disposed on the adjustment bracket 2261. Moreover, the conveyor belt adjustment structure 226 may include an adjustment guide rod 2266, one end of which is connected to the adjustment bracket 2261 and the other end of which is connected to the fixed conveyor support frame 2222, and the movable conveyor support frame 2222 may be movably sleeved on the adjustment guide rod 2266. In this embodiment, an adjustment guide rod 2266 may be disposed on each side of the adjustment bracket 2261, and both adjustment guide rods 2266 move side-by-side through the movable conveyor support frame 2222 from the side and connect to the fixed conveyor support frame 2222.

[0059] Furthermore, the linear transmission structure 2264 of the conveyor belt adjustment structure 226 can also be a screw and nut transmission structure, including an adjusting screw rotatably disposed between the adjustment bracket 2261 and the fixed conveyor support frame 2222, and an adjusting nut threadedly connected to the adjusting screw. The adjusting nut can be disposed on the movable conveyor support frame 2222, and the adjustment drive structure 2262 is connected to the adjusting screw. In this embodiment, two linear transmission structures 2264 can also be provided. The adjusting screws of the two linear transmission structures 2264 can be rotatably disposed side-by-side on both sides of the adjustment bracket 2261 and rotatably connected to the fixed conveyor support frame 2222. The adjusting nuts of the two linear transmission structures 2264 can be disposed on both sides of the movable conveyor support frame 2222, allowing simultaneous driving movement of the movable conveyor support frame 2222 from both sides. The two adjusting guide rods 2266 can also simultaneously guide the movable conveyor support frame 2222, ensuring smooth and reliable movement of the movable conveyor support frame 2222.

[0060] Furthermore, in this embodiment, the conveyor belt adjustment structure 226 may include an adjustment drive structure 2262, which can be simultaneously connected to two adjusting screws, driving both screws at the same time. This allows for synchronous driving from both sides of the movable conveyor support frame 2222, resulting in greater stability and reliability. To facilitate synchronous driving of the two adjusting screws, the conveyor belt adjustment structure 226 may also include a synchronous transmission structure 2263 connected to the two adjusting screws. Further, the synchronous transmission structure 2263 may include a synchronous adjusting wheel respectively mounted on each of the two adjusting screws, and a synchronous adjusting belt or chain connected between the two synchronous adjusting wheels. Additionally, the conveyor belt adjustment structure 226 may include two adjustment drive structures 2262, each connected to one of the two adjusting screws, allowing for independent driving of each adjusting screw.

[0061] Furthermore, in this embodiment, the adjustment drive structure 2262 can be configured as a drive handwheel connected to the adjustment screw, or as a drive motor connected to the adjustment screw. This allows the linear transmission structure 2264 of the conveyor belt adjustment structure 226 to be driven manually or automatically. In addition, to facilitate the movement of the movable conveyor support frame 2222, a guide adjustment slide rail can be provided on the lifting support top seat 216 of the loading lifting frame structure 210, and the movable conveyor support frame 2222 can be slidably mounted on the guide adjustment slide rail, making the movement of the conveyor support frame 2222 smoother.

[0062] In addition, such as Figures 7 to 10 As shown, the feeding gripper mechanism 204 may include a gripper lateral drive structure 230 disposed on the top of the frame 100, a gripper lifting drive structure 240 connected to the gripper lateral drive structure 230, and a pressure bar gripper structure 250 disposed on the gripper lifting drive structure 240. The pressure bar gripper structure 250 is disposed vertically and vertically with the feeding lifting conveyor structure 202 and the pressure head elasticity detection structure 310. The lateral drive structure 230 of the gripper can drive the pressing strip gripper structure 250 to reciprocate between the loading station and the inspection station, so that the pressing strip gripper structure 250 moves above the loading lifting conveyor structure 202 or above the pressing head elasticity detection structure 310. Furthermore, the lifting drive structure 240 of the gripper can drive the pressing strip gripper structure 250 to move vertically closer to or further away from the loading lifting conveyor structure 202, facilitating the gripper structure 250 to grasp the pressing strip clamp 20 on the loading lifting conveyor structure 202; it can also drive the pressing strip gripper structure 250 to move vertically closer to or further away from the pressing head elasticity detection structure 310, facilitating the gripper structure 250 to place the pressing strip clamp 20 on the pressing head elasticity detection structure 310. Moreover, both the lateral drive structure 230 and the lifting drive structure 240 of the gripper can be configured as motor-driven or cylinder-driven structures.

[0063] Furthermore, the clamping jaw structure 250 may include a clamping jaw mounting base 252 disposed on the clamping jaw lifting drive structure 240, a bidirectional telescopic drive member 254 disposed on the clamping jaw mounting base 252, and a clamping jaw plate structure 256 respectively connected to both sides of the bidirectional telescopic drive member 254. The clamping jaw lifting drive structure 240 can drive the two clamping jaw plate structures 256 to move up and down, causing the clamping structure formed by the two clamping jaw plate structures 256 to move closer to or further away from the clamping jaw fixture 20; while the bidirectional telescopic drive member 254 can telescopically move the clamping jaw plate structures 256 on both sides, causing the two clamping jaw plate structures 256 to move closer to or further away from each other, so that the clamping structure formed by the two clamping jaw plate structures 256 can clamp or release the clamping jaw fixture 20. In addition, the bidirectional telescopic drive member 254 may be a double-headed drive cylinder, capable of driving both ends separately. In addition, the bidirectional telescopic drive structure 254 can also be replaced by a unidirectional drive structure, such as a common drive cylinder, which can drive one pressure bar clamping plate structure 256 to move closer to or further away from the other pressure bar clamping plate structure 256.

[0064] Furthermore, the clamping jaw structure 250 may also include a clamping plate sliding guide rail 255 protruding from both sides of the clamping jaw mounting base 252; and the clamping plate structure 256 may include a clamping plate connecting plate 2562 slidably disposed on the two clamping plate sliding guide rails 255, and a clamping plate body 2564 with a clamping hook 2566 correspondingly disposed at the end of each clamping plate connecting plate 2562. The clamping plate bodies 2564 on both sides are arranged opposite to each other, and the two clamping plate connecting plates 2562 are respectively connected to the two output ends of the bidirectional telescopic drive member 254. By sliding the clamping plate connecting plate 2562 of the clamping plate structure 256 on the clamping plate sliding guide rail 255, the clamping plate structure 256 can slide stably along the clamping plate sliding guide rail 255 under the drive of the bidirectional telescopic drive member 254, thereby allowing the two clamping plate bodies 2564 to stably and reliably move closer or further apart from each other.

[0065] Furthermore, the clamping jaw structure 250 may also include a jaw positioning bracket 253 respectively disposed on the two clamping plate sliding guide rails 255, and a clamping positioning head 258 disposed on the jaw positioning bracket 253. The clamping positioning head 258 may be disposed on the inner side of the clamping plate body 2564 and used for positioning and detecting the two sides of the clamping jaw 20. Specifically, the jaw positioning bracket 253 may be fixed to the clamping plate sliding guide rail 255, may be partially bent vertically downward and extended through the clamping plate connecting plate 2562, may be arranged side by side with the clamping plate body 2564, and may be located on the side of the clamping plate body 2564 near the bidirectional telescopic drive member 254. When the pressure strip clamp 20 is clamped by the pressure strip clamping claw structure 250, the two sides of the pressure strip clamp 20 can be positioned by the two clamping positioning heads 258 respectively. After the pressure strip clamp 20 is positioned, the pressure strip clamp 20 can be accurately gripped by the clamping structure formed by the two clamping plates 2564.

[0066] In addition, such as Figure 11 As shown, the pressure head elasticity detection structure 310 of the pressure strip elasticity detection mechanism 300 may include a detection base plate 312 disposed on the frame 100, a base plate connection structure 314 disposed on the detection base plate 312, and an elasticity detection sensor structure 316 disposed on the detection base plate 312. The detection base plate 312 is disposed vertically and vertically corresponding to the loading gripper mechanism 204 and the unloading gripper mechanism 404. The base plate connection structure 314 (which may be a slot or a protrusion) can be used to achieve a detachable connection with the pressure strip clamp 20. The loading gripper mechanism 204 can grasp and move the pressure strip clamp 20 conveyed by the loading lifting conveyor structure 202 to the detection base plate 312 of the pressure head elasticity detection structure 310, making the pressure strip clamp 20 detachably connected to the base plate connection structure 314 on the detection base plate 312. This allows the elasticity detection sensor structure 316 on the detection base plate 312 to correspond with the spring pressure head on the pressure strip clamp 20 to detect its elasticity. After the elasticity detection of the pressure strip clamp 20 is completed, the unloading gripper mechanism 404 can detach the pressure strip clamp 20 from the base plate connection structure 314 on the detection base plate 312 and clamp the pressure strip clamp 20 to transfer it to the unloading lifting conveyor structure 402. Moreover, the elasticity detection sensor structure 316 may include multiple pressure sensors provided on the detection base plate 312, which can be used to correspond one-to-one with multiple spring pressure heads on the pressure strip clamp 20 to detect its elasticity. By using multiple pressure sensors mounted on the detection base plate 312, the elastic force of multiple spring pressure heads on the pressure bar clamp 20 can be detected simultaneously, making the detection more efficient. In addition, the pressure head elasticity detection structure 310 may include a detection support frame 311 mounted on the frame 100, and the detection base plate 312 may be mounted on the detection support frame 311.

[0067] Furthermore, the pressure bar clamp 20 may include a clamping plate, multiple spring pressure heads embedded in the middle of the clamping plate, positioning protrusions around the clamping plate, and a snap-fit ​​connection structure at each of the opposite side edges of the clamping plate. Moreover, the pressure bar gripper structure 250 of the loading gripper mechanism 204 may also include a toggle block structure 257 protruding from the inner side (the side closest to the bidirectional telescopic drive member) of the clamping plate body 2564 and / or the clamping plate connecting plate 2562. The toggle block structure 257 can be used to actuate the snap-fit ​​connection structure on the pressure bar clamp 20 to engage or disengage the pressure bar clamp 20 from the pressure head spring force detection structure 310. The multiple spring pressure heads on the pressure bar clamp 20 can press multiple components on the circuit board for easy soldering.

[0068] When inspecting the pressure strip clamp 20, the pressure strip clamp 20 is first clamped and moved to the position of the detection base plate 312 of the pressure head spring force detection structure 310 by the pressure strip clamping claw structure 250, so that the positioning protrusion of the pressure strip clamp 20 corresponds to the positioning hole provided on the detection base plate 312 to achieve positioning. Moreover, when the pressure strip clamping claw structure 250 clamps or releases the pressure strip clamp 20, the latching connection structure at the side edge of the pressure strip clamp 20 can be moved by the actuating block structure 257 protruding on the inner side of the pressure strip clamping claw structure 250, so that the latching connection structure of the pressure strip clamp 20 can be detachably connected or released from the base plate connection structure on the detection base plate 312, thereby connecting or releasing the pressure strip clamp 20 and the pressure head spring force detection structure 310. Furthermore, the snap-fit ​​connection structure may include a snap-fit ​​connecting plate with a clamp hook rotatably disposed outside the side of the clamp plate, with the top of the snap-fit ​​connecting plate protruding from the top surface of the clamp plate and its bottom protruding below the bottom surface of the clamp plate. The clamp hook may be disposed at the bottom of the snap-fit ​​connecting plate. The actuating block structure 257 may be located on both sides of the snap-fit ​​connecting plate of the pressure strip clamp 20. The clamp hook 2566 of the clamping plate body 2564 may be disposed at the lower part of the clamping plate body 2564 and correspond to the bottom of the clamp plate. When the two clamping plates 2564 approach or move away from the pressure strip clamp 20, the actuating block structure 257 may compress the top of the snap-fit ​​connecting plate of the pressure strip clamp 20, causing it to rotate forward or backward, thereby opening or retracting the clamp hook at the bottom of the snap-fit ​​connecting plate to facilitate clamping or releasing the detection substrate.

[0069] In addition, such as Figure 2 , Figure 12 , Figure 13The online pressure bar elasticity measuring device 10 shown may further include a defective product storage mechanism 500 mounted on the frame 100. This defective product storage mechanism 500 may be located below the pressure head elasticity detection structure 310 and may correspond approximately to the unloading lifting and conveying structure 402. After the pressure head elasticity detection structure 310 detects that the pressure bar clamp 20 has unqualified elasticity, the unqualified pressure bar clamp 20 can be gripped by the unloading gripper mechanism 404 and transferred to the unloading lifting and conveying structure 402. The unqualified pressure bar clamp 20 is then transferred to the defective product storage mechanism 500 for storage via the unloading lifting and conveying structure 402. Furthermore, by placing the defective product storage mechanism 500 below the pressure head elasticity detection structure 310, the overall structure becomes more compact, saving equipment space.

[0070] Specifically, the defective product storage mechanism 500 may include a defective product conveying structure 510 mounted on the frame 100, a defective product storage bin 520 protruding above the defective product conveying structure 510, and a defective product lifting structure 530 mounted on the frame 100. The defective product lifting structure 530 is located in the middle of the defective product conveying structure 510 and corresponds vertically to the defective product storage bin 520. The defective product conveying structure 510 and the unloading lifting conveying structure 402 are arranged side by side. The unloading lifting conveying structure 402 can convey defective clamping strips 20 to the defective product conveying structure 520, and the defective product lifting structure 530 can lift the defective clamping strips 20 on the defective product conveying structure 520 to the defective product storage bin 520 for storage.

[0071] Furthermore, in this embodiment, the non-conforming product conveying structure 510 is similar in structure to the feeding conveyor belt structure 220, and will not be described again here. The non-conforming product storage bin 520 may include multiple storage plates 522 disposed on the non-conforming product conveying structure 510, and a storage cavity for storing non-conforming pressure strip clamps 20 is formed between the multiple storage plates 522. Moreover, a rotatable storage limiting block 524 protrudes from the bottom of the storage plate 522. The storage limiting block 524 can be flipped upward but cannot be flipped downward, so that the non-conforming product lifting structure 530 can lift the non-conforming pressure strip clamps 20 from the bottom of the non-conforming product storage bin 520 into the storage cavity, and the pressure strip clamps 20 in the storage cavity will not fall down (they will be blocked by the storage limiting block 524). Furthermore, the defective product lifting structure 530 may include a defective product lifting cylinder 532 mounted on the frame 100, and a defective product lifting plate 534 mounted on the top of the defective product lifting cylinder 532. The defective product lifting plate 534 is located below the defective product conveying structure 510 and may correspond vertically to the pressure bar clamp 20 on the defective product conveying structure 510.

[0072] In addition, such as Figures 1 to 3 ,as well as Figure 7 As shown, the material feeding mechanism 400 of the pressing strip feeding mechanism 400 may include a material feeding lifting frame structure 410 provided on the frame 100, and a material feeding conveyor belt structure 420 provided on the material feeding lifting frame structure 410. The material feeding gripper mechanism 404 is arranged vertically in correspondence with the pressing head elasticity detection structure 310 and the material feeding conveyor belt structure 420. Similarly, the unloading lifting frame structure 402 can lift and move the unloading conveyor belt structure 420, allowing it to connect with external pressure strip receiving mechanisms located at different heights, facilitating the transfer of qualified pressure strip clamps 20 to the external pressure strip receiving mechanisms. Furthermore, the height of the unloading conveyor belt structure 420 can correspond to the height of the pressure head elasticity detection structure 310 of the pressure strip elasticity detection mechanism 300, facilitating the transfer of pressure strip clamps 10 from the pressure head elasticity detection structure 30 to the unloading conveyor belt structure 420 by the unloading gripper mechanism 404. Moreover, the height of the unloading conveyor belt structure 420 can correspond to the height of the non-conforming product conveying structure 510, allowing non-conforming pressure strip clamps 20 to be moved from the unloading conveyor belt structure 420 to the non-conforming product conveying structures 510 arranged side-by-side for offline storage.

[0073] Furthermore, the unloading lifting frame structure 410 may include a lifting support base 212 mounted on the frame 100, a seat lifting drive structure 214 connected to the lifting support base 212, and a lifting support top seat 216 connected to the seat lifting drive structure 214. The unloading conveyor belt structure 420 is mounted on top of the lifting support top seat 216. Moreover, the unloading conveyor belt structure 420 may include a conveyor belt frame 222 mounted on top of the unloading lifting frame structure 410, a conveyor belt structure 224 mounted on the conveyor belt frame 222, and a conveyor belt adjustment structure 226 connected to the conveyor belt frame 222. The specific structure of the unloading lifting frame structure 410 is similar to that of the loading lifting frame structure 210, and the specific structure of the unloading conveyor belt structure 420 is similar to that of the loading conveyor belt structure 220; therefore, further details will not be provided here.

[0074] Furthermore, the unloading gripper mechanism 404 may include a gripper lateral drive structure 230 disposed on the top of the frame 100, a gripper lifting drive structure 240 connected to the gripper lateral drive structure 230, and a pressure bar gripper structure 250 disposed on the gripper lifting drive structure 240. The pressure bar gripper structure 250 is vertically corresponding to the pressure head elasticity detection structure 310 and the unloading lifting conveying structure 402. The specific structure of the unloading gripper mechanism 404 is similar to that of the loading gripper mechanism 204, and will not be described in detail here.
