Description

Technical Field

[0001] The present invention relates to the technical field of circuit board detection, and specifically, it is a debuggable coupled circuit board comprehensive detection device. Background Art

[0002] A coupled board circuit board is a mechanical device that allows an antenna coupler installed in a mobile adapter to transmit radio frequency energy between a portable radio antenna system and an external antenna with minimal coupling loss. Among them, the detection mainly includes mechanical performance testing and environmental adaptability testing. By subjecting the coupled board to impact and vibration, the stability under mechanical stress is evaluated, and at the same time, the overall performance under high humidity and high heat environments is simulated to ensure subsequent stable operation.

[0003] The prior art discloses a Chinese patent with the application number CN202011351634.3, a strength detection device for circuit board production, and discloses repeatedly bending a circuit board to detect the anti-bending pressure of the circuit board, and at the same time quickly clamping and fixing two circuit boards.

[0004] The above device can only perform bending tests on a single circuit board. However, in actual use, after the circuit board is impacted, it will also generate a reverse force on the impact piece. At this time, fixing the circuit board cannot truly simulate the actual situation of the circuit board in use. At the same time, when performing humidity and heat tests on the circuit board, fixing the circuit board cannot evenly apply the humid and hot steam to the surface of the circuit board.

[0017] Beneficial effects of the present invention:

[0018] 1. The present invention can knock the coupling plates conveyed sequentially on the conveying unit through the setting of the detection unit to detect the strength performance of the surface of the coupling plates, and open the two supporting plates to support the lower part of the coupling plates, so that the detection unit can support the coupling plates when impacting, and prevent the coupling plates from falling after being impacted. The setting of the regulating branch chain can support the four corner edges of the coupling plates of different specifications when the coupling plates of different specifications are placed in the return frame, so that the upper and lower surfaces of the coupling plates are fully exposed when the coupling plates are subjected to environmental testing, and at the same time, when the external force is impacted on the outside of the coupling plates, the coupling plates can be prevented from sliding and displacement.

[0019] 2. The present invention can, through the setting of the vibration branch chain, make it possible for the whole return frame to drive the coupling plate to impact up and down when the coupling plate is impacted by external force. At this time, the coupling plate can also generate an upward counter-impact force, which greatly enhances the strength of the coupling plate during the impact test. Moreover, with the setting of the spring in the vibration branch chain, the return frame drives the coupling plate to vibrate at multiple frequencies, and then when detecting the strength of the coupling plate, the performance of the coupling plate under vibration can also be detected. Compared with the existing coupling plate detection device, the present invention can perform knocking vibration on the fixed coupling plate to detect the impact resistance of the coupling plate. At the same time, under the action of the vibration branch chain, the coupling plate can vibrate at multiple frequencies after being impacted, and can also perform a reverse impact toward the detection unit, which greatly increases the impact force of the coupling plate during the impact test.

[0020] 3. The present invention has multiple clamping units, so it can continuously test batches of coupling plates, and when any one of the clamping units is transported to the bottom of the detection unit through the conveying unit, the coupling plate that has been tested can be taken out, and the untested coupling plate can be placed at the same time without affecting the detection operation of other coupling plates. The humidification unit can be used to humidify the outside of the coupling plate to simulate the performance of the coupling plate under different humidities during actual use, and the atomized gas can be humidified and heated in the humidification unit, so that when the humidification unit increases the humidity on the outside of the coupling plate, the temperature also rises, thereby realizing that when the coupling plate is subjected to environmental testing, the heat resistance test and humidity test of the coupling plate are carried out simultaneously.

[0021] 4. In the present invention, the humidifying unit is located between two conveying units and below the clamping unit. When the clamping unit is above the conveying belt, the mist and hot air sprayed by the humidifying unit can act on the lower end face of the coupling plate. As the conveying unit conveys the clamping unit, when the clamping unit is below the conveying belt, the upper end face of the coupling plate faces the humidifying unit at this time, and the atomized hot air sprayed by the humidifying unit acts on the upper end face of the coupling plate. Furthermore, when performing environmental tests on multiple coupling plates, the atomized hot air sprayed by the humidifying unit acts evenly on both sides of the coupling plate, making the humidity and heat received by the coupling plate more uniform. Cooperating with existing external detectors can record the heat resistance and thermal stability of the coupling plate, enabling it to truly simulate and detect the performance of the coupling plate in a humid and hot environment. Compared with the existing device, when the present invention performs performance detection on a batch of coupling plates in a humid and hot environment, as the clamping unit carrying the coupling plate moves on the conveying unit, the two sides of the coupling plate can be successively oriented towards the humidifying unit, realizing the impact of atomized hot air on both sides of the coupling plate, without the need for manual turning of the coupling plate.

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0036] As Figures 1-10 shown, a debuggable coupled circuit board comprehensive detection device includes a base 1. Two symmetrically arranged conveying units are fixedly installed on the upper end surface of the base 1. A plurality of clamping units for placing the coupled board during environmental testing are commonly installed between the two conveying units. A vibration chain is provided on the clamping unit. A return frame 31 is provided on the clamping unit. Adjusting chains suitable for fixing coupled boards of different specifications are provided on both sides of the return frame 31. Two corresponding supporting plates 36 are rotatably installed on the lower end surface of the return frame 31. A detection unit for detecting the strength performance of the coupled board is fixedly installed on one side of the upper end surface of the base 1. A humidifying unit for humidifying the outside of the coupled board is commonly provided between the two conveying units.

[0037] The setting of the detection unit can perform a knocking operation on the coupled boards sequentially conveyed on the conveying unit to detect the strength performance of the surface of the coupled board, and open the two supporting plates 36 to support the lower part of the coupled board, so that the detection unit can hold and place the coupled board when it impacts, avoiding the coupled board from falling after being impacted;

[0038] When different specifications of coupling plates are placed inside the U-shaped frame 31, the adjustable branch chain can clamp the four corners of the coupling plates with different specifications, so that when the coupling plates are undergoing environmental tests, the upper and lower surfaces of the coupling plates are fully exposed. At the same time, when an external force impacts the outside of the coupling plates, the coupling plates can be prevented from sliding and displacing;

[0039] When the coupling plates are impacted by an external force, the vibration branch chain enables the entire U-shaped frame 31 to drive the coupling plates to undergo up-and-down impacts. At this time, the coupling plates can also generate an upward reaction force, greatly enhancing the strength of the coupling plates during impact tests. And with the springs provided in the vibration branch chain, the U-shaped frame 31 drives the coupling plates to vibrate multiple times. Furthermore, when detecting the strength of the coupling plates, the performance of the coupling plates under vibration conditions can also be detected. Compared with the existing coupling plate detection devices, the present invention can knock and vibrate the fixed coupling plates to detect the impact resistance of the coupling plates. At the same time, under the action of the vibration branch chain, the coupling plates can vibrate multiple times after being impacted, and can also impact in the reverse direction towards the detection unit, greatly intensifying the impact force when the coupling plates are undergoing impact tests.

[0040] Since multiple clamping units are provided, continuous testing of batch coupling plates can be carried out. And when any one of the clamping units is transported by the conveying unit to be below the detection unit, the detected coupling plates can be taken out, and at the same time, the untested coupling plates can be placed, without affecting the detection operations of other coupling plates. Through the setting of the humidifying unit, humidifying operations can be carried out on the outside of the coupling plates to simulate the performance of the coupling plates under different humidities during actual use. And the humidifying unit can humidify and heat the atomized gas, so that when the humidifying unit strengthens the humidity of the outside of the coupling plates, the temperature also rises. Thus, when carrying out environmental tests on the coupling plates, the heat resistance test and humidity test of the coupling plates are carried out synchronously;

[0041] Since the humidifying unit is located between the two conveying units and below the clamping unit, when the clamping unit is above the conveying belt 22, the mist and hot air sprayed by the humidifying unit can act on the lower end face of the coupling plate. As the conveying unit conveys the clamping unit, when the clamping unit is below the conveying belt 22, at this time, the upper end face of the coupling plate faces the humidifying unit, and the atomized hot air sprayed by the humidifying unit at this time acts on the upper end face of the coupling plate. Furthermore, when performing environmental tests on multiple coupling plates, the atomized hot air sprayed by the humidifying unit acts evenly on both sides of the coupling plate, making the humidity and heat received by the coupling plate more uniform. Cooperating with the existing external detector can record the heat resistance and thermal stability of the coupling plate, enabling it to truly simulate and detect the performance of the coupling plate in a humid and hot environment. Compared with the existing device, the present invention can, when detecting the performance of a batch of coupling plates in a humid and hot environment, as the clamping unit carrying the coupling plate moves on the conveying unit, the two sides of the coupling plate can be successively oriented towards the humidifying unit, realizing the impact of atomized hot air on both sides of the coupling plate, without the need for manual turning of the coupling plate.

[0042] The conveying unit includes two groups of symmetrically arranged support plates 20. On one side of each group of support plates 20, a conveying wheel 21 is rotatably installed through a motor, and a conveying belt 22 is commonly installed between the two conveying wheels 21 on each group of support plates 20.

[0043] The clamping unit includes two symmetrically arranged connecting plates 30. The two connecting plates 30 are respectively connected to their corresponding conveying belts 22. Corner plates 32 are fixedly installed at the four corners of the U-shaped frame 31. A storage groove is jointly formed between the corner plates 32 and the U-shaped frame 31. A positioning frame 33 is slidably installed in the storage groove. When multiple positioning frames 33 approach each other, the coupling plates placed on the supporting plate 36 can be clamped at the corners, thus ensuring that the coupling plates remain stable when performing impact tests to detect their strength. At the same time, when the supporting plate 36 cancels the support for the coupling plates, by clamping the four corners and edges of the coupling plates, the upper and lower surfaces of the coupling plates can be fully exposed, so as to facilitate subsequent contact with atomized hot air on the upper and lower surfaces of the coupling plates. When multiple positioning frames 33 move away from each other, at this time, the clamping of the four corners of the coupling plates is cancelled, and at this time, it is convenient to quickly take out the coupling plates from the U-shaped frame 31.

[0044] The regulation branch chain includes an adjustment groove opened on the upper end face of the corner plate 32. The adjustment groove communicates with the storage groove. A restraint rod 331 fixed to the positioning frame 33 is provided in the adjustment groove. Electric push rods 34 symmetrically arranged are fixedly installed on the front and rear sides of the U-shaped frame 31. A regulation plate 35 is fixedly installed at the telescopic end of the electric push rod 34. Traction grooves are opened on both sides of the regulation plate 35, and the traction grooves on both sides are respectively sleeved outside the restraint rods 331 on both sides.

[0045] By controlling the retraction of the electric push rods 34 on both sides, at this time, the two regulating plates 35 move closer to the loop-shaped frame 31. When the regulating plate 35 moves, the restraint rods 331 are pulled through the traction grooves. At this time, the multiple restraint rods 331 drive the multiple positioning frames 33 to approach each other, so as to clamp coupling plates of different specifications. Thus, when the whole device detects the coupling plate, the applicability is more extensive. When the two electric push rods 34 are pushed forward, the two regulating plates 35 move away from each other. At this time, the multiple restraint rods 331 drive the multiple positioning frames 33 to move away from each other, thereby canceling the fixation of the coupling plate, so that the coupling plate can be quickly removed from the loop-shaped frame 31.

[0046] The vibration branch chain includes two side plates 301 respectively fixed to the two connecting plates 30. A corrugated groove 302 is formed in the middle of the side plate 301. A moving member 303 is slidably installed in the corrugated groove 302. The two moving members 303 on both sides are respectively fixed to the two sides of the loop-shaped frame 31. A spring is commonly connected between the moving member 303 and the side plate 301.

[0047] Since the moving member 303 slides in the corrugated groove 302 and is jacked up by the spring force, at this time, the coupling plate in the loop-shaped frame 31 is not pressed by external force. The moving member 303 drives the loop-shaped frame 31 to be placed above the corrugated groove 302. When the strength of the coupling plate in the loop-shaped frame 31 is detected, due to the external impact force on the coupling plate, the coupling plate generates a downward force. The loop-shaped frame 31 and the moving member 303 slide down in the corrugated groove 302 and press the spring downward. At the same time, the moving member 303 slides back and forth along the track of the corrugated groove 302, which can expand the contact surface when the coupling plate is subjected to an impact test. Compared with knocking the whole coupling plate, through the displacement of the coupling plate, multi-point contact is realized, which can make the strength detection of the coupling plate more real and comprehensive. When the detection unit moves upward and cancels the impact contact with the coupling plate, under the action of the spring, the moving member 303 is jacked up upward. At this time, the two moving members 303 on both sides drive the coupling plate in the loop-shaped frame 31 to impact upward multiple times. On the one hand, the upward impact realizes a reverse impact force on the detection unit, increasing the impact strength of the coupling plate. On the other hand, it can also impact different contact surfaces of the coupling plate.

[0048] Two symmetrically arranged supporting plates 36 are rotatably installed on the lower end surface of the loop-shaped frame 31. Accommodating grooves 361 are formed in the front and rear sides of the supporting plate 36. Displacement blocks 362 are slidably installed in the accommodating grooves 361. Two symmetrically arranged rack plates 37 are slidably installed on the front and rear sides of the loop-shaped frame 31 through electric sliders. The rack plate 37 is arranged in an H shape, and tooth teeth are provided on both sides of the rack plate 37.

[0049] When the two supporting plates 36 are moved away from each other to cancel the support for the bottom of the coupling plate, the electric slider is activated to drive the rack plate 37 to slide downward. When the rack plate 37 slides downward, it drives the two side gears 371 to rotate away from each other. When the two gears 371 rotate away from each other, they synchronously drive the two side folding plates 372 to flip outward. When the folding plates 372 flip outward, they push the supporting plates 36 through the displacement blocks 362. At this time, the two supporting plates 36 rotate away from each other, thereby canceling the support for the coupling plate, which facilitates the subsequent double-sided humidification operation of the coupling plate.

[0050] On both sides of the rack plate 37, there are gears 371 rotatably connected to the U-shaped frame 31. The gears 371 are meshed with the rack plate 37. On the side of the gear 371 away from the U-shaped frame 31, a folding plate 372 is fixedly installed. On the side of the folding plate 372 away from the gear 371, it is fixed to the displacement block 362.

[0051] The detection unit includes a U-shaped frame 40. On one side of the middle of the U-shaped frame 40, a motor 41 is fixedly installed. The output end of the motor 41 is fixedly installed with a driving rod 42 rotatably connected to the U-shaped frame 40. On the driving rod 42, a plurality of pressing wheels 43 arranged at equal intervals are fixedly installed. Below the driving rod 42, there is a middle frame 44 fixed to the U-shaped frame 40. On the middle frame 44, a plurality of knocking members 45 corresponding to the pressing wheels 43 are slidably installed. At the bottom end of the knocking member 45, a rubber block 46 is fixedly installed. Inside the rubber block 46, there is a pressure sensor. The knocking member 45 is sleeved with a spring outside. At the top of the knocking member 45, an electric push plate 47 is fixedly installed. At the top of the electric push plate 47, an arc plate 48 is fixedly installed. When the motor 41 is started, the motor 41 drives the driving rod 42 to rotate. When the driving rod 42 rotates, it synchronously drives a plurality of pressing wheels 43 to rotate. When the pressing wheels 43 rotate, they can press the knocking members 45 on the middle frame 44 downward. After being pressed downward, the knocking members 45 impact the surface of the coupling plate, thereby completing the measurement of the compressive performance of the coupling plate. And through the setting of the rubber block 46, the surface of the coupling plate can be protected to avoid the knocking member 45 directly acting on the surface of the coupling plate and causing wear on the outside of the coupling plate. At the same time, the pressure sensor inside the rubber block 46 can also monitor the pressure received by the coupling plate and control the lifting of the electric push plate 47 to drive the arc plate 48 to move up and down, so as to regulate the knocking intensity of the knocking member 45.

[0052] The humidification unit includes two zigzag plates 50 fixedly connected to the support plate 20. Between the two zigzag plates 50, a telescopic frame 51 is jointly hinged. At one end of the telescopic frame 51 away from the zigzag plate 50, there is a connecting frame 52 fixed to the support plate 20. A cylinder 53 is jointly installed at the middle of the connecting frame 52 and one side of the telescopic frame 51.

[0053] At the upper end surface of the telescopic frame 51, a plurality of atomizing spray plates 55 arranged at equal intervals are fixedly installed. On one side of the atomizing spray plate 55, there is a water supply tank 54 placed on the base 1. A plurality of water delivery pipes 56 connected to the atomizing spray plate 55 are installed on the water supply tank 54. The arrangement of the water delivery pipes 56 can convey the water in the water supply tank 54 into the atomizing spray plate 55, so that after the atomizing spray plate 55 sprays out hot steam, it acts on the surface of the coupling plate, thereby simulating the service performance of the coupling plate in a humid and hot environment. When quickly regulating the concentration of the hot steam sprayed out by the atomizing spray plate 55, the cylinder 53 is opened to expand and contract. When the cylinder 53 extends forward, the telescopic frame 51 is unfolded. At this time, the distance between the atomizing spray plates 55 arranged at equal intervals on the telescopic frame 51 is enlarged. At this time, the density between the hot steam sprayed out from the plurality of atomizing spray plates 55 is reduced. On the contrary, when the cylinder 53 retracts backward, the atomizing spray plates 55 are closely arranged, and then the hot steam gathers and impacts upward uniformly.

[0054] When the present invention is in use, when the two positioning frames 33 approach each other, they can clamp the corners of the coupling plate placed on the supporting plate 36, thereby ensuring that the coupling plate remains stable when performing an impact test to detect its strength. At the same time, when the supporting plate 36 cancels the support for the coupling plate, by clamping the four corners and edges of the coupling plate, the upper and lower surfaces of the coupling plate can be fully exposed, so as to facilitate subsequent contact with atomized hot air on the upper and lower surfaces of the coupling plate. When the plurality of positioning frames 33 move away from each other, the clamping of the four corners of the coupling plate is cancelled at this time, and it is convenient to quickly take out the coupling plate from the return frame 31. Control the retraction of the electric push rods 34 on both sides. At this time, the two regulating plates 35 move closer to the return frame 31. When the regulating plate 35 moves, the pulling rod 331 is pulled through the traction groove. At this time, the plurality of pulling rods 331 drive the plurality of positioning frames 33 to approach each other, and then the coupling plates of different specifications can be clamped, so that the applicability of the entire device is more extensive when detecting the coupling plate. When controlling the forward push of the two electric push rods 34, the two regulating plates 35 move away from each other at this time. At this time, the plurality of pulling rods 331 drive the plurality of positioning frames 33 to move away from each other, and then the fixing of the coupling plate is cancelled, so as to quickly remove the coupling plate from the return frame 31;

[0055] The moving member 303 slides within the corrugated groove 302 and is lifted under the action of the spring. At this time, the coupling plate within the figure-eight frame 31 is not under the external pressing force. The moving member 303 drives the figure-eight frame 31 to be placed above the corrugated groove 302. When the strength of the coupling plate within the figure-eight frame 31 is detected, due to the external impact force on the coupling plate, a downward force is generated on the coupling plate. The figure-eight frame 31 and the moving member 303 slide downward within the corrugated groove 302 and press the spring downward. At the same time, the moving member 303 slides back and forth along the trajectory of the corrugated groove 302, enabling the coupling plate to expand the contact surface during the impact test. Compared with knocking on the entire coupling plate, through the displacement of the coupling plate, multi-point contact is achieved, enabling the strength detection of the coupling plate to be more real and comprehensive. When the detection unit moves upward to cancel the impact contact with the coupling plate, under the action of the spring, the moving member 303 is lifted upward. At this time, the moving members 303 on both sides drive the coupling plate within the figure-eight frame 31 to perform multiple upward impacts. On the one hand, a reverse impact force is applied to the detection unit through the upward impact, increasing the impact strength of the coupling plate. On the other hand, different contact surfaces of the coupling plate can also be impacted;

[0056] When the two supporting plates 36 are moved away from each other to cancel the support of the bottom of the coupling plate, the electric slider is activated to drive the rack plate 37 to slide downward. When the rack plate 37 slides downward, it drives the two side gears 371 to rotate away from each other. When the two gears 371 rotate away from each other, they simultaneously drive the two side folding plates 372 to flip outward. When the folding plates 372 flip outward, they push the supporting plates 36 through the displacement blocks 362. At this time, the two supporting plates 36 rotate away from each other, thereby canceling the support of the coupling plate, facilitating subsequent humidification operations on both sides of the coupling plate. The motor 41 is activated, and the motor 41 drives the driving rod 42 to rotate. When the driving rod 42 rotates, it simultaneously drives multiple pressing wheels 43 to rotate. When the pressing wheels 43 rotate, they can press the knocking member 45 on the middle frame 44 downward. The knocked-down knocking member 45 impacts the surface of the coupling plate, thereby completing the measurement of the compressive performance of the coupling plate. And through the setting of the rubber block 46, the surface of the coupling plate can be protected, preventing the knocking member 45 from directly acting on the surface of the coupling plate and causing external wear of the coupling plate. At the same time, the pressure sensor within the rubber block 46 can also monitor the pressure received by the coupling plate and control the lifting of the electric push plate 47 to drive the arc plate 48 to move up and down, enabling the regulation of the knocking strength of the knocking member 45;

[0057] The water delivery pipe 56 is provided to convey the water in the water supply tank 54 into the atomizing spray plate 55, so that the atomizing spray plate 55 sprays out hot steam and acts on the surface of the coupling plate, thereby simulating the service performance of the coupling plate in a humid and hot environment. When quickly regulating the concentration of the hot steam sprayed out by the atomizing spray plate 55, the cylinder 53 is opened to expand and contract. When the cylinder 53 extends forward, the telescopic frame 51 is unfolded. At this time, the distance between the atomizing spray plates 55 arranged at equal intervals on the telescopic frame 51 is enlarged, and the density of the hot steam sprayed out from multiple atomizing spray plates 55 is reduced. On the contrary, when the cylinder 53 retracts backward, the atomizing spray plates 55 are closely arranged, and then the hot steam gathers and impacts upward uniformly to act on the surface of the coupling plate.
