Description

Technical Field

[0001] The invention relates to the technical field of electronic component testing, and in particular to an automatic testing device for electronic components. Background Art

[0002] Electronic components are basic elements in electronic circuits. They are usually individually packaged and have two or more contacts or pins. The number and position of pins of electronic components of the same model and type are consistent. Electronic components need to be tested before leaving the factory to ensure that they function properly. Conventional testing requires manual measurement of contacts, which is not only inefficient, but also easy to cause damage to the components. After the test is completed, qualified electronic components need to be packaged. Electronic component testing devices in the prior art usually require manual placement and cannot achieve fully automatic inspection. At the same time, unqualified and qualified electronic components cannot be effectively packaged, and the degree of automation is low. Summary of the invention

[0005] Furthermore, a suction mechanism is provided on the inner sliding column, and the suction device includes an air pump fixedly installed on the inner sliding column, an air pipe fixedly installed on the air pump, a fixed pipe fixedly installed on the inner sliding column, the air pipe is connected to the fixed pipe, a rotating pipe is rotatably installed on the fixed pipe, a suction cup is fixedly installed on the rotating pipe, the rotating pipe is connected to the fixed pipe, a rotating gear is fixedly installed on the rotating pipe, a fixed rack is fixedly installed on the base frame, the fixed rack is meshed with the rotating gear, and an upper switch and a lower switch are fixedly installed on the base frame.

[0006] Furthermore, a one-way mechanism is provided on the base frame, and the one-way mechanism includes an upper transmission wheel rotatably mounted on the base frame, a lower transmission wheel fixedly mounted on the main transmission wheel, a vertical transmission belt wrapped around the lower transmission wheel and the upper transmission wheel, a plurality of shifting teeth are provided on the vertical transmission belt, a rotating tooth is rotatably mounted on the lower frame, and a torsion spring is provided between the rotating tooth and the lower frame.

[0007] Furthermore, a placing mechanism is provided on the base frame, and the placing mechanism includes a sliding frame slidably mounted on the base frame, a feed slope is fixedly mounted on the sliding frame, an upper triangular block is fixedly mounted below the sliding frame, a sliding spring is provided between the upper triangular block and the base frame, and a lower triangular block is fixedly mounted on the lifting outer frame.

[0008] The electronic components to be tested are placed on the feed belt, with the pins in the pin slots. The air pump, air pipe, fixed pipe, and rotating pipe drive the suction cup to adsorb the electronic components. The lifting electric cylinder extends to drive the inner sliding column to rise along the bottom frame, thereby driving the lifting frame, lifting outer frame, and lower frame to rise. When the inner sliding column rises, it brings the electronic components up together through the suction cup. Under the action of the fixed rack, it drives the rotating gear and the rotating pipe to rotate 180 degrees. At the same time, the lifting outer frame rises and pushes the upper triangle block, the sliding frame, and the feed slope toward the transmission belt through the lower triangle block. The sliding spring is compressed. When the rotating pipe contacts the upper switch, the air pump controls the suction cup to release the electronic components. The electronic components fall onto the feed slope and finally slide onto the transmission belt. When the lower frame rises, it drives the rotating gear to rise. The rotating gear pushes the vertical transmission belt to rotate through the toggle gear, thereby driving the lower transmission wheel to rotate, thereby driving the main transmission wheel to rotate, thereby driving the feed belt to move. The feed belt moves the next electronic component to the bottom of the transmission belt. After the electronic component is placed on the transmission belt, the lifting electric cylinder descends, and the feed slope is reset under the action of the sliding spring. The rotating tube rotates ninety degrees back to the initial position, and the rotating tube contacts the lower switch. At this time, the air pump controls the suction cup to adsorb the next electronic component. When the lower shelf descends, the rotating gear contacts the toggle gear, and the rotating gear will not drive the toggle gear and the vertical transmission belt to move. The rotating gear rotates relative to the lower shelf, and the torsion spring is compressed. When the rotating gear passes the toggle gear, the torsion spring drives the rotating gear to reset, and this reciprocating process is used to continuously place electronic components on the transmission belt.

[0009] Furthermore, the detection device includes a motor wheel fixedly mounted on the motor shaft of the transmission motor, an active transmission wheel rotatably mounted on the collection frame, an oblique transmission belt is wound around the active transmission wheel and the motor wheel, a transmission belt is wound around the active transmission wheel and the driven wheel, a descending column is slidably mounted on the lifting frame, a compression spring is arranged between the descending column and the lifting frame, a laminating frame is fixedly mounted on the descending column, a detection module is fixedly mounted below the laminating frame, and a plurality of pins are arranged on the detection module, corresponding to the pins of the electronic components.

[0010] Furthermore, a blocking mechanism is provided on the laminating frame, and the blocking mechanism comprises a blocking rod slidably mounted on the laminating frame, a blocking plate is fixedly mounted on the blocking rod, and a blocking spring is provided between the blocking plate and the laminating frame.

[0011] The rotation of the transmission motor drives the motor wheel to rotate, thereby driving the active transmission wheel to rotate through the oblique transmission belt, thereby driving the transmission belt to transport the rotating gear that falls on it. When the lifting frame descends, it will drive the descending column and the bonding frame to descend. First, the blocking plate contacts the transmission belt. The blocking plate is used to block the advancement of the electronic component. Then the pins of the detection module contact the pins of the electronic component. The electronic component is detected through the detection module. When the detection module and the electronic component are docked, the lifting frame continues to descend, and the blocking spring and the compression spring will be compressed, so that the pins of the detection module are in close contact with the pins of the electronic component. After the detection is completed, the lifting frame rises, driving the blocking plate to rise, and the transmission belt transports the electronic component to the flip frame.

[0012] Furthermore, the collecting device includes a discharge frame and a discharging frame fixedly mounted on the collecting rack, a switching electric cylinder fixedly mounted on the collecting rack, a switching rod fixedly mounted on the top of the switching electric cylinder, a flip frame rotatably mounted on the collecting rack, an indicator light fixedly mounted on the collecting rack, and a sensor fixedly mounted on the side of the discharging frame.

[0013] Furthermore, the discharging frame is provided with a drop-in mechanism, and the drop-in mechanism includes a transverse blocking plate slidably mounted on the discharging frame, a transverse moving frame is fixedly mounted on the transverse blocking plate, a transverse moving rack is fixedly mounted on the transverse moving frame, an intermediate column is fixedly mounted on the discharging frame, an intermediate gear is rotatably mounted on the intermediate column, a lifting rack is fixedly mounted on the lifting frame, the lifting rack is meshed with the intermediate gear, and the intermediate gear is meshed with the transverse moving rack.

[0014] Furthermore, a packing mechanism is provided on the collecting rack, and the packing mechanism includes a motor rack fixedly installed on the collecting rack, a material receiving motor is fixedly installed on the motor rack, a gear is fixedly installed on the motor shaft of the material receiving motor, a driving gear and an external driven wheel are rotatably installed on the collecting rack, a motor transmission belt is wound around the gear and the driving gear, a push frame belt is wound around the external driven wheel and the driving gear, a push frame plate is fixedly installed on the push frame belt, a plurality of ball bearings are provided on the collecting rack, a material receiving frame is placed on the ball bearings, a push plate is slidably installed on the collecting rack, and a reset spring is provided between the push plate and the collecting rack.

[0015] The test result of the electronic component is displayed on the indicator light. When the test is qualified, the switching electric cylinder does not move, and the electronic component is transported to the flip frame by the transmission belt and slides into the discharge frame. In the initial state, the horizontal blocking plate is located in the discharge frame, and the electronic component will fall onto the horizontal blocking plate. The sensor senses the electronic component and controls the receiving motor to rotate once. The rotation of the receiving motor drives the active gear to rotate through the motor transmission belt, and the push plate is pushed to slide along the collection frame through the push frame belt and the push frame plate. The reset spring is stretched, thereby pushing the receiving frame to slide a short distance in the direction of the lifting frame through the push plate. When the lifting frame descends, it drives the lifting rack to descend, thereby driving the intermediate gear to rotate, thereby driving the traverse rack, the traverse frame and the horizontal blocking plate to move along the discharge frame. Move outward. When the horizontal blocking plate leaves the discharge frame, the electronic components originally on the horizontal blocking plate fall into the receiving frame. When the lifting frame rises, it will drive the horizontal blocking plate back to the discharge frame. The receiving frame moves a small distance each time, so that the electronic components will not be stacked. When the receiving frame is full, it will leave the collection rack. At this time, the receiving motor reverses and drives the push frame plate to reset. The push plate resets under the rebound of the reset spring. When the electronic component fails the test, the switching electric cylinder extends, driving the switching rod to push the flip frame to rotate, so that the flip frame slopes toward the discharge frame, and the electronic components transported by the transmission belt fall into the discharge frame through the flip frame and are finally discharged. Then the switching electric cylinder contracts, and the switching rod pushes the flip frame to rotate and reset to the initial state.

[0032] The electronic component 112 to be tested is placed on the feed belt 111, and the pin is located in the pin groove 113. The suction cup 106 is driven by the air pump 103, the air pipe 104, the fixed pipe 132, and the rotating pipe 105 to absorb the electronic component 112. The lifting cylinder 117 extends to drive the inner sliding column 102 to rise along the bottom frame 101, thereby driving the lifting frame 118, the lifting outer frame 124 and the lower frame 121 to rise. When the inner sliding column 102 rises, it rises with the electronic component 112 through the suction cup 106, and the fixed rack 120 Under the action of the upper switch 130, the air pump 103 controls the suction cup 106 to release the electronic component 112, and the electronic component 112 falls onto the feeding slope 129 and finally slides onto the transmission belt 108. When the lower shelf 121 rises, it will drive the upper triangle block 127, the sliding frame 126 and the feeding slope 129 to move toward the transmission belt 108.

When the electronic component 112 is placed on the transmission belt 108, the lifting cylinder 117 descends, and the feed slope 129 is reset under the action of the sliding spring 128. The rotating tube 105 rotates 90 degrees to return to the initial position, and the rotating tube 1 05 contacts with the lower switch 131. At this time, the air pump 103 controls the suction cup 106 to absorb the next electronic component 112. When the lower shelf 121 descends, the rotating tooth 122 contacts with the toggle tooth 116. The rotating tooth 122 will not drive the toggle tooth 116 and the vertical transmission belt 115 to move. The rotating tooth 122 rotates relative to the lower shelf 121, and the torsion spring is compressed. When the rotating tooth 122 passes through the toggle tooth 116, the torsion spring drives the rotating tooth 122 to reset, and this reciprocating process is used to continuously place the electronic component 112 on the transmission belt 108.

[0033] like Figure 5 , Figure 6As shown, the detection device includes a motor wheel 211 fixedly mounted on the motor shaft of the transmission motor 201, an active transmission wheel 203 is rotatably mounted on the collection frame 301, an oblique transmission belt 202 is wound around the active transmission wheel 203 and the motor wheel 211, a transmission belt 108 is wound around the active transmission wheel 203 and the driven wheel 107, a descending column 204 is slidably mounted on the lifting frame 118, a compression spring 205 is arranged between the descending column 204 and the lifting frame 118, a laminating frame 206 is fixedly mounted on the descending column 204, a detection module 210 is fixedly mounted below the laminating frame 206, and a plurality of pins are arranged on the detection module 210, corresponding to the pins of the electronic component 112.

The electronic component 112 is detected by the detection module 210. After the detection module 210 is docked with the electronic component 112, the lifting frame 118 continues to descend, and the blocking spring 208 and the clamping spring 205 will be compressed, so that the pins of the detection module 210 are in close contact with the pins of the electronic component 112. After the detection is completed, the lifting frame 118 rises, driving the blocking plate 209 to rise, and the transmission belt 108 transports the electronic component 112 to the flip frame 307.

[0039] The test result of the electronic component 112 is displayed on the indicator light 323. When the test is qualified, the switching electric cylinder 304 does not move, and the electronic component 112 is transported to the flip frame 307 by the transmission belt 108 and slides into the discharge frame 313. In the initial state, the horizontal blocking plate 312 is located in the discharge frame 313, and the electronic component 112 will fall on the horizontal blocking plate 312. The sensor 322 senses the electronic component 112 and controls the material receiving motor 316 to rotate once. The material receiving motor 316 rotates through the motor transmission The driving belt 317 drives the driving gear 318 to rotate, and the push plate 325 is pushed to slide along the collecting frame 301 through the push frame belt 319 and the push frame plate 324. The reset spring 321 is stretched, so that the push plate 325 pushes the receiving frame 314 to slide a short distance in the direction of the lifting frame 118. When the lifting frame 118 descends, it drives the lifting rack 302 to descend, thereby driving the intermediate gear 309 to rotate, thereby driving the traverse rack 310, the traverse frame 311 and the traverse blocking plate 312 to move along the discharging The frame 313 moves outward. When the horizontal blocking plate 312 leaves the material discharging frame 313, the electronic components 112 originally on the horizontal blocking plate 312 fall into the receiving frame 314. When the lifting frame 118 rises, it will drive the horizontal blocking plate 312 back to the material discharging frame 313. The receiving frame 314 moves a small distance each time, so that the electronic components 112 will not be piled up. When the receiving frame 314 is full, it will leave the collecting frame 301. At this time, the receiving motor 316 reverses to drive the push frame plate 324 Reset, the push plate 325 is reset under the rebound of the reset spring 321. When the electronic component 112 fails the test, the switching cylinder 304 extends, driving the switching rod 305 to push the flip frame 307 to rotate, so that the flip frame 307 slopes toward the discharge frame 303, and the electronic components 112 transported by the transmission belt 108 pass through the flip frame 307 and fall into the discharge frame 303, and are finally discharged. Then the switching cylinder 304 contracts, and the switching rod 305 pushes the flip frame 307 to rotate and reset to the initial state.

[0040] The working principle of the electronic component automatic testing device disclosed in the present invention is as follows: an electronic component 112 to be tested is placed on a feed belt 111, and the pins are located in pin grooves 113. The suction cup 106 is driven by the air pump 103, the air pipe 104, the fixed pipe 132, and the rotating pipe 105 to adsorb the electronic component 112. The lifting electric cylinder 117 is extended to drive the inner sliding column 102 to rise along the bottom frame 101, thereby driving the lifting frame 118, the lifting outer frame 124, and the lower frame 121 to rise. When the inner sliding column 102 rises, it carries the electronic component 112 through the suction cup 106. The electronic component 112 rises together, and under the action of the fixed rack 120, the rotating gear 119 and the rotating tube 105 are driven to rotate 180 degrees. At the same time, the lifting outer frame 124 rises and pushes the upper triangular block 127, the sliding frame 126 and the feeding slope 129 toward the transmission belt 108 through the lower triangular block 125. The sliding spring 128 is compressed. When the rotating tube 105 contacts the upper switch 130, the air pump 103 controls the suction cup 106 to release the electronic component 112, and the electronic component 112 falls onto the feeding slope 129 and finally slides onto the transmission belt 108. When the lower rack 121 rises, it drives the rotating gear 122 to rise. The rotating gear 122 drives the vertical transmission belt 115 to rotate by the toggle gear 116, thereby driving the lower transmission wheel 114 to rotate, thereby driving the main transmission wheel 109 to rotate, thereby driving the feed belt 111 to move, and the feed belt 111 moves the next electronic component 112 to the bottom of the transmission belt 108. When the electronic component 112 is placed on the transmission belt 108, the lifting cylinder 117 descends, and the feed slope 129 is reset under the action of the sliding spring 128, and the rotating tube 105 rotates 90 degrees to return to the initial position. The rotating tube 105 contacts the lower switch 131. At this time, the air pump 103 controls the suction cup 106 to absorb the next electronic component 112. When the lower shelf 121 descends, the rotating tooth 122 contacts the toggle tooth 116. The rotating tooth 122 will not drive the toggle tooth 116 and the vertical transmission belt 115 to move. The rotating tooth 122 rotates relative to the lower shelf 121, and the torsion spring is compressed. When the rotating tooth 122 passes the toggle tooth 116, the torsion spring drives the rotating tooth 122 to reset, and this reciprocating process is carried out to continuously place the electronic component 112 on the transmission belt 108.The transmission motor 201 rotates to drive the motor wheel 211 to rotate, thereby driving the active transmission wheel 203 to rotate through the inclined transmission belt 202, thereby driving the transmission belt 108 to transport the rotating gear 122 that falls thereon. When the lifting frame 118 descends, it will drive the descending column 204 and the bonding frame 206 to descend. First, the blocking plate 209 contacts the transmission belt 108. The blocking plate 209 is used to block the advancement of the electronic component 112. Then, the pins of the detection module 210 contact the pins of the electronic component 112. The electronic component 112 is detected by the detection module 210. After the detection module 210 is docked with the electronic component 112, the lifting frame 118 continues to descend, and the blocking spring 208 and the clamping spring 205 will be compressed, so that the pins of the detection module 210 are in close contact with the pins of the electronic component 112. After the detection is completed, the lifting frame 118 rises, driving the blocking plate 209 to rise, and the transmission belt 108 transports the electronic component 112 to the flip frame 307. The test result of the electronic component 112 is displayed on the indicator light 323. When the test is qualified, the switching electric cylinder 304 does not move, and the electronic component 112 is transported to the flip frame 307 by the transmission belt 108 and slides into the discharge frame 313. In the initial state, the horizontal blocking plate 312 is located in the discharge frame 313, and the electronic component 112 will fall on the horizontal blocking plate 312. The sensor 322 senses the electronic component 112 and controls the material receiving motor 316 to rotate once. The material receiving motor 316 rotates through the motor transmission The driving belt 317 drives the driving gear 318 to rotate, and the push plate 325 is pushed to slide along the collecting frame 301 through the push frame belt 319 and the push frame plate 324. The reset spring 321 is stretched, so that the push plate 325 pushes the receiving frame 314 to slide a short distance in the direction of the lifting frame 118. When the lifting frame 118 descends, it drives the lifting rack 302 to descend, thereby driving the intermediate gear 309 to rotate, thereby driving the traverse rack 310, the traverse frame 311 and the traverse blocking plate 312 to move along the discharging The frame 313 moves outward. When the horizontal blocking plate 312 leaves the material discharging frame 313, the electronic components 112 originally on the horizontal blocking plate 312 fall into the receiving frame 314. When the lifting frame 118 rises, it will drive the horizontal blocking plate 312 back to the material discharging frame 313. The receiving frame 314 moves a small distance each time, so that the electronic components 112 will not be piled up. When the receiving frame 314 is full, it will leave the collecting frame 301. At this time, the receiving motor 316 reverses to drive the push frame plate 324 Reset, the push plate 325 is reset under the rebound of the reset spring 321. When the electronic component 112 fails the test, the switching cylinder 304 extends, driving the switching rod 305 to push the flip frame 307 to rotate, so that the flip frame 307 slopes toward the discharge frame 303, and the electronic components 112 transported by the transmission belt 108 pass through the flip frame 307 and fall into the discharge frame 303, and are finally discharged. Then the switching cylinder 304 contracts, and the switching rod 305 pushes the flip frame 307 to rotate and reset to the initial state.

[0041] When the inner sliding column 102 and the lifting frame 118 rise, the transmission belt 108 transports the electronic components 112 to the transmission belt 108, and at the same time the feed belt 111 rotates once, the transverse blocking plate 312 is inserted into the discharge frame 313, the electronic components 112 fall onto the transverse blocking plate 312, and the receiving frame 314 moves forward once; when the inner sliding column 102 and the lifting frame 118 descend, the detection module 210 detects the electronic components 112, the transverse blocking plate 312 is pulled out of the discharge frame 313, and the electronic components 112 fall into the receiving frame 314.
