The No. 1 transmission belt 5, the No. 2 transmission belt 11 and the No. 3 transmission belt 17 are all driven by motors.

[0040] A circuit board 19 is commonly arranged between the two No. 1 transmission belts 5 and the two No. 2 transmission belts 11, and is respectively located on two parallel sides of the circuit board 19. The circuit board 19 is transmitted between the No. 1 transmission belt 5 and the No. 3 transmission belt 17, and the pins of the circuit board 19 are arranged upward.

[0041] During operation, the existing electronic component detection device has a slow detection speed and is not suitable for large-scale circuit board electronic component detection, and it is unable to automatically remove unqualified products, resulting in low detection efficiency and poor convenience of use. In this solution, during normal operation, the motor drives two No. 1 transmission belts 5, two No. 2 transmission belts 11 and two No. 3 transmission belts 17, and the transmission directions of the lower surfaces of the two No. 1 transmission belts 5 and the upper surfaces of the two No. 2 transmission belts 11 and two No. 3 transmission belts 17 are consistent, and the two sets of swing limit assemblies are blocked between the No. 1 transmission belt 5 and the No. 2 transmission belt 11. In the initial state, the No. 1 electric push rod 12 will remain in an extended state so that the swing plate 9 is kept in a horizontal state, so that the No. 2 transmission belt 11 and the No. 1 transmission belt are 5, and the conveying surfaces of the No. 2 conveyor belt 11 and the No. 3 conveyor belt 17 are located at the same horizontal plane. During continuous detection, the circuit board 19 is placed from the ends of the No. 2 conveyor belt 11 and the No. 1 conveyor belt 5, so that the two parallel sides of the circuit board 19 are respectively placed between the two No. 1 conveyor belts 5 and the two No. 2 conveyor belts 11, and the No. 2 conveyor belt 11 and the No. 1 conveyor belt 5 are driven by the motor to convey the circuit board 19 toward the No. 3 conveyor belt 17.

Finally, the qualified circuit board 19 will be conveyed from the other end of the No. 3 transmission belt 17. When the detection path between the electronic components of the circuit board 19 is unqualified, the No. 1 electric push rod 12 will shrink. When the No. 1 electric push rod 12 shrinks, it will drive the swing plate 9 to swing downward with the rotation connection with the No. 2 vertical plate 8 as the axis, and on the No. 4 transmission wheel 13 Under the support and limit of the No. 5 transmission wheel 14, the end of the No. 2 transmission belt 11 close to the No. 3 transmission belt 17 will bend downward, and the circuit board 19 that fails the inspection between the No. 2 transmission belt 11 and the No. 1 transmission belt 5 will be transported downward and fall into the collecting tank 18, and then the unqualified products will be rejected. After the rejection is completed, the No. 1 electric push rod 12 will extend. At this time, the extension of the No. 1 electric push rod 12 will drive the swing plate 9 to swing upward with the rotation connection axis with the No. 2 vertical plate 8 as the axis, so that the No. 2 transmission belt 11 returns to its original state for the next inspection. By putting the circuit board 19 from the ends of the No. 2 transmission belt 11 and the No. 1 transmission belt 5 in turn, and detecting each electronic component on the circuit board 19 through the lifting detection assembly, the cooperation achieves the effect of continuous detection.Compared with the traditional single-element detection device, it has higher detection efficiency and can automatically remove unqualified products, effectively improving the convenience of use.

[0042] See also Figure 4-9 As shown, the lifting detection assembly includes a fixed plate 20, and the fixed plate 20 is installed between the top ends of the two side support plates 2 at the same time. Four No. 2 electric push rods 21 are vertically installed downward under the fixed plate 20, and two side fixing frames 22 are horizontally installed at the bottom ends of the four No. 2 electric push rods 21. Limiting grooves 24 are respectively provided on the inner sides of the two side fixing frames 22, and positioning plates 25 are slidably arranged in the two limiting grooves 24.

[0043] A mounting plate 23 for fixing is commonly installed on the two side fixing frames 22, through holes 32 are provided on the sides of the two side fixing frames 22, and No. 2 threaded holes 33 are provided on both sides of the positioning plate 25 corresponding to the two through holes 32 respectively, and fixing bolts 34 for fixing the positioning plate 25 are penetrated through the through holes 32. The fixing bolts 34 can penetrate the through holes 32 and be set in the No. 2 threaded holes 33, and a detection information processing module 35 is installed on the fixing plate 20.

[0044] The positioning plate 25 is evenly provided with No. 1 threaded holes 26, and a detection probe 27 is arranged in the No. 1 threaded hole 26. The detection probe 27 includes an outer shell 28, and a threaded groove is arranged on the outer side of the outer shell 28. A detection probe 29 is penetrated through the outer shell 28, and an interlocking groove 30 corresponding to the pin of the circuit board 19 is arranged at the bottom end of the detection probe 29. The top end of the detection probe 29 is connected to the detection information processing module 35 through a signal line, and a hexagonal plate 31 is arranged on the outer side of the outer shell 28.

[0045] The swing limiting assembly includes a support rod 36, which is installed on the side of the side support plate 2 facing the No. 3 transmission belt 17. A No. 1 hollow shaft 37 is installed at the other end of the support rod 36. A rotating shaft 38 is rotatably installed in the No. 1 hollow shaft 37. A connecting rod 39 is horizontally installed on the top of the rotating shaft 38. A No. 2 hollow shaft 40 is installed at the other end of the connecting rod 39. A No. 3 electric push rod 41 is horizontally swung installed in the No. 2 hollow shaft 40, and the other end of the No. 3 electric push rod 41 is rotatably installed on the side of the side support plate 2. A baffle bar 42 is installed at the bottom end of the rotating shaft 38 opposite to the connecting rod 39, and the baffle bar 42 is horizontally arranged between the No. 2 transmission belt 11 and the No. 1 transmission belt 5, and is perpendicular to the transmission direction of the No. 1 transmission belt 5.

[0046] During operation, in order to ensure the normal use of the detection device in this scheme, improve the applicable scope of detection, and be able to detect circuit boards of different models and sizes, in this scheme, the detection probe 27 is installed on the positioning plate 25 as needed, and the installation position of the detection probe 27 corresponds to the pin position on the circuit board 19, and the extension length of the connecting rod 39 is controlled to adjust the blocking position of the blocking bar 42. When the extension length of the connecting rod 39 is long, the swing range of the end of the blocking bar 42 with the rotating shaft 38 as the axis will increase. On the contrary, when the extension length of the connecting rod 39 is short, the swing range of the end of the limit groove 24 with the rotating shaft 38 as the axis will decrease, so as to block the circuit board 19 of different models and sizes, so that the circuit board 19 can accurately block the stop. When the No. 2 electric push rod 21 extends downward, it will drive the detection probe 27 installed thereon to descend through the positioning plate 25, so that the detection probe 27 contacts the pins on the circuit board 19, and the pins will be inserted into the fitting groove 30, so as to increase the contact area between the pins and the detection probe 29 and improve the detection accuracy. When in use, the fixing bolt 34 can be unscrewed from the No. 2 threaded hole 33 and the through hole 32 to remove the positioning plate 25 from between the two side fixing frames 22, and the installation position of the detection probe 27 can be adjusted to be suitable for detection of electronic components on circuit boards of different models and sizes. The purpose of electronic component detection is achieved and the scope of application of detection is effectively improved.

[0047] Working principle: during normal operation, the motor drives two No. 1 transmission belts 5, two No. 2 transmission belts 11 and two No. 3 transmission belts 17, and makes the transmission direction of the lower surface of the two No. 1 transmission belts 5 consistent with the transmission direction of the upper surface of the two No. 2 transmission belts 11 and the two No. 3 transmission belts 17, and makes the two sets of swing limit assemblies blocked between the No. 1 transmission belt 5 and the No. 2 transmission belt 11. In the initial state, the No. 1 electric push rod 12 will remain in the extended state, so that the swing plate 9 is kept in the horizontal state, the No. 2 transmission belt 11 is parallel to the No. 1 transmission belt 5, and the upper conveying surfaces of the No. 2 transmission belt 11 and the No. 3 transmission belt 17 are located in the same horizontal plane. During continuous detection, the circuit board 19 is put in from the ends of the No. 2 transmission belt 11 and the No. 1 transmission belt 5. The two parallel sides of the circuit board 19 are respectively placed between the two No. 1 transmission belts 5 and the two No. 2 transmission belts 11, and the No. 2 transmission belt 11 and the No. 1 transmission belt 5 are driven by the motor to transport the circuit board 19 to the direction of the No. 3 transmission belt 17. When the circuit board 19 is transported to the end of the No. 2 transmission belt 11 close to the No. 3 transmission belt 17 and is located between the No. 4 transmission wheel 13 and the No. 3 transmission wheel 10, the circuit board 19 will be blocked by the swing limit assembly. At this time, the motor stops driving and controls the lifting detection assembly to move downward. The electronic components are tested for qualified passage through the lifting detection assembly. After the test is qualified, the swing limit assembly will open to both sides, and the lifting detection assembly will move upward to restore its original position for the next test, and the motor will drive again The second transmission belt 11 and the first transmission belt 5 are driven to convey the circuit board 19 to the third transmission belt 17. At this time, the circuit board 19 will be conveyed from between the second transmission belt 11 and the first transmission belt 5 to between the third transmission belt 17 and the first transmission belt 5. Finally, the qualified circuit board 19 will be conveyed from the other end of the third transmission belt 17. When the detection path between the electronic components of the circuit board 19 is unqualified, the first electric push rod 12 will shrink. When the first electric push rod 12 shrinks, it will drive the swing plate 9 to swing downward with the rotation connection with the second vertical plate 8 as the axis. Under the support and limit of the fourth transmission wheel 13 and the fifth transmission wheel 14, the end of the second transmission belt 11 close to the third transmission belt 17 will bend downward, and the end between the second transmission belt 11 and the first transmission belt will bend downward. The circuit boards 19 that fail the inspection between the transmission belts 5 will be transported downward and fall into the collecting trough 18, and then the unqualified products will be rejected. After the rejection is completed, the No. 1 electric push rod 12 will be extended. At this time, the extension of the No. 1 electric push rod 12 will drive the swing plate 9 to swing upward with the rotation connection axis with the No. 2 vertical plate 8 as the axis, so that the No. 2 transmission belt 11 returns to its original state for the next inspection. By placing the circuit boards 19 from the ends of the No. 2 transmission belt 11 and the No. 1 transmission belt 5 in turn, and inspecting each electronic component on the circuit board 19 through the lifting inspection assembly, the cooperation achieves the effect of continuous inspection. Compared with the traditional single-component inspection device, the inspection efficiency is higher, and the unqualified products can be automatically rejected, which effectively improves the convenience of use.

[0048] By installing the detection probe 27 on the positioning plate 25 as needed, and the installation position of the detection probe 27 corresponds to the pin position on the circuit board 19, and controlling the extension length of the connecting rod 39, so as to adjust the blocking position of the blocking bar 42. When the extension length of the connecting rod 39 is long, the swing range of the end of the blocking bar 42 with the rotating shaft 38 as the axis will increase. On the contrary, when the extension length of the connecting rod 39 is short, the swing range of the end of the limiting groove 24 with the rotating shaft 38 as the axis will decrease, so as to block the circuit board 19 of the model size, so that the circuit board 19 can be accurately blocked and stopped under the positioning plate 25. During the detection, the No. 2 electric push rod 21 will extend downward. When the No. 2 electric push rod 21 extends downward, it will drive the detection probe 27 installed thereon to descend through the positioning plate 25, so that the detection probe 27 contacts the pins on the circuit board 19, and the pins will be stuck in the fitting groove 30, so as to increase the contact area between the pins and the detection probe 29, improve the detection accuracy, and when in use, unscrew the fixing bolt 34 from the No. 2 threaded hole 33 and the through hole 32, then the positioning plate 25 can be removed from between the two side fixing frames 22, and the installation position of the detection probe 27 can be adjusted to be suitable for the detection of electronic components on circuit boards of different models and sizes, thereby achieving the purpose of electronic component detection and effectively improving the scope of application of detection.
