Technical Field

[0001] The invention relates to the technical field of parts assembly machines, in particular to an automatic detection parts assembly machine. Background Art

[0002] The mobile phone circuit board is the core device of the mobile phone. It processes the data and instructions sent from the mobile phone input module, and then sends the processing results to the mobile phone output module. In the production process of mobile phone circuit boards, parts assembly machines are often used to install various components on the circuit board body.

[0003] When existing parts assembly machines assemble circuit boards, they often send them to testing equipment for testing after assembly. Unqualified products are screened and then reworked. The transportation process is time-consuming, and most testing equipment can only perform a single item test at a time, making it difficult to perform comprehensive testing of multiple items on circuit boards at the same time.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an automatic detection parts assembly machine is proposed. Summary of the invention

The lower end of the pressure plate is fixedly connected to the pressure plate, and the upper surface of the pressure plate is fixedly connected to a joint.

[0010] Furthermore, the pressure rod is hook-shaped, the pressure block is prism-shaped, the pressure springs have different heights, and the pressure plate is elastically connected to the bottom plate through the pressure springs, the contacts are snap-connected to the connectors, and the warning lights correspond one-to-one with the pressure rod, pressure block, and contact positions, and are electrically connected through internal circuits.

[0011] Furthermore, the connecting assembly includes a moving rod, a sliding groove and a sliding block. The left end of the pressure plate is rotatably connected to the moving rod, and a sliding groove is provided on the left side of the moving rod. The sliding groove is engaged with the sliding block.

[0012] Furthermore, the connecting assembly also includes a fixed rod and a fixed pin, the fixed rod is fixedly connected to the left side of the slider, and the lower end of the fixed rod is rotatably connected to the fixed pin, the moving rod and the fixed rod are both L-shaped, and the slider is slidably connected to the moving rod through a sliding groove.

[0013] Furthermore, the material placing assembly includes a base, a material placing trough, a top spring and a pad.

[0015] Furthermore, the material placement assembly also includes a rail, a block, a plate and a spring.

A plate is fixedly connected to the top of the block, and a spring is fixedly connected to the side of the plate close to the inner wall of the placement slot, and the plate is elastically connected to the placement slot through the spring.

[0016] The present invention provides an automatic detection parts assembly machine, which has the following beneficial effects: when in use, it can simultaneously perform component position detection, circuit path detection and voltage resistance detection on a circuit board, and can automatically unload after the detection is completed, and sort the circuit boards according to the detection results.

[0017] 1. When the present invention is in use, the main board of the circuit board is placed on the left side of the chassis. After the push rod drives the clamping plate to clamp the main board, the mechanical arm can assemble the circuit board. After the assembly is completed, the push rod drives the clamping plate to release the clamping, and the telescopic rod drives the push plate to move to the right in the cavity, which can drive the push rod to move to the right in the guide rail, push the circuit board onto the pad and make it located in the center of the pad, and the lifting rod drives the pressure plate to descend, and the material is detected by the cooperation of the detection component and the material placement component. When the pressure plate descends, the slider can slide on the moving rod through the slide groove to prevent the moving rod from hindering the descent of the pressure plate. Keep the connection between the movable plate and the fixed plate. After the inspection is completed, the lifting rod can drive the pressure plate to rise. When the slider moves to the lower end of the slide slot, the movable plate can drive the fixed plate to rise through the slider, thereby driving the fixed pin to slide on the base, and then driving the base to rotate in the placement slot. According to different inspection results, the lifting rod can drive the pressure plate to rise by different distances, thereby driving the base to rotate at different angles in the placement slot through the connecting component, so that the circuit board can slide along the base with different inclinations to the corresponding material guide plate, thereby completing the sorting of the circuit board, so that unqualified products can be screened out for rework.

[0018] 2. When the circuit board is tested, the pressing plate can drive the bottom plate to descend, thereby driving the pressing plate to descend through the compression spring, applying pressure to the component to detect whether the component is firmly assembled. As the pressing plate descends, the compression spring and the top spring are compressed, allowing the circuit board to enter the material placement groove until the contact contacts the joint. If the component installation position is not offset, the pressing plate can remain horizontal so that the contact can be normally connected to the joint, thereby energizing the indicator light above the contact to light it up. If the component installation position is offset, the pressing plate will deflect during the compression of the compression spring, thereby causing the joint to deflect, the contact cannot be connected to the joint, and the indicator light is not on. At this time, whether the component installation position is deflected can be detected according to the flashing of the indicator light. At the same time, the pressing plate and the pad can cooperate with each other under the action of the compression spring and the top spring to apply pressure to the circuit board, thereby detecting the pressure resistance of the front side of the circuit board, and compression springs of different lengths can adapt to components of different sizes and heights, thereby ensuring that the contact can contact the joint at the same time when the bottom plate descends, avoiding misjudgment due to different contact times between the contact and the joint.

[0019] 3. When the present invention performs a positive withstand voltage test on the circuit board, the pressure plate can drive the pressure rod and the pressure block to descend synchronously. The pressure rod first contacts the slide plate, thereby pressing the slide plate to move in the slide groove through its own inclined surface and stretching the tension spring, so that the slide plate squeezes the left and right sides of the circuit board. The slide groove can limit the slide plate to prevent the slide plate from deflecting when moving. At the same time, the pressure rod longitudinally energizes the circuit board through the slide plate. If the longitudinal circuit of the circuit board is a passage, the indicator light connected to the pressure rod lights up, and the longitudinal circuit test is qualified. If the longitudinal circuit of the circuit board is a break, the indicator light connected to the pressure rod does not light up, and the longitudinal circuit test is unqualified. When the pressure block contacts the card board, the slide plate can move back in the slide groove under the action of the tension spring, so that the slide plate is out of contact with the circuit board. At this time, the pressure block presses the card board to approach the circuit board and stretches the spring, so that the card board presses the front and back sides of the circuit board. During extrusion, the card block can limit the card plate through the card slot to prevent the card plate from deflecting when moving. At the same time, the pressure block energizes the circuit board longitudinally through the card plate. If the longitudinal circuit of the circuit board is a passage, the indicator light connected to the pressure rod will light up, and the longitudinal circuit detection is qualified. If the longitudinal circuit of the circuit board is a break, the indicator light connected to the pressure rod will not light up, and the longitudinal circuit detection is unqualified. When detecting the longitudinal circuit, since the slide plate does not contact the circuit board, mutual interference during detection can be avoided. After all detections are completed, the lifting rod drives the pressure plate to rise, and the pressure rod can drive the slide plate to move again through its own inclined surface to prevent the slide plate from getting stuck with the pressure rod and hindering the pressure plate from rising. At the same time, the top spring drives the pad to reset, and pushes the circuit board out of the trough for easy unloading. If the circuit board is not broken after the pressure plate rises, the circuit board passes the pressure test. BRIEF DESCRIPTION OF THE DRAWINGS

When the circuit board is tested, the pressure plate 12 can drive the bottom plate 1302 to descend, thereby driving the pressure plate 1307 to descend through the compression spring 1305, applying pressure to the component to detect whether the component is firmly assembled. As the pressure plate 12 descends, the compression spring 1305 and the top spring 1603 are compressed, allowing the circuit board to enter the loading groove 1602 until the contact 1306 contacts the connector 1308. If the component installation position is not offset, the pressure plate 1307 can remain horizontal so that the contact 1306 can be normally connected to the connector 1308, thereby energizing the indicator light above the contact 1306 to light up. If the component installation position is offset, the pressure plate 1307 will be pressed during the process of compressing the compression spring 1305. Deflection occurs, resulting in the deflection of connector 1308, contact 1306 cannot be connected to connector 1308, and the indicator light is off. At this time, the component installation position can be detected whether it is deflected according to the on and off of the indicator light. At the same time, the pressing plate 1307 and the pad 1604 can cooperate with each other to apply pressure to the circuit board under the action of the compression spring 1305 and the top spring 1603, so as to detect the positive pressure resistance of the circuit board. The compression springs 1305 of different lengths can adapt to components of different sizes and heights, so as to ensure that the contact 1306 can contact the connector 1308 at the same time when the bottom plate 1302 descends, so as to avoid misjudgment caused by different contact times between the contact 1306 and the connector 1308. When the circuit board is subjected to a positive pressure resistance test, the pressing plate 12 can drive the pressing rod 1 303 and the pressing block 1304 descend synchronously, the pressing rod 1303 first contacts with the slide plate 1607, thereby pressing the slide plate 1607 to move in the slide groove 1402 through its own inclined surface and stretching the tension spring 1606, so that the slide plate 1607 squeezes the left and right sides of the circuit board, and the slide groove 1402 can limit the slide plate 1607 to prevent the slide plate 1607 from deflecting when moving. At the same time, the pressing rod 1303 conducts longitudinal power to the circuit board through the slide plate 1607. If the longitudinal circuit of the circuit board is a passage, the indicator light connected to the pressing rod 1303 lights up, and the longitudinal circuit test is qualified. If the longitudinal circuit of the circuit board is a break, the indicator light connected to the pressing rod 1303 is off, and the longitudinal circuit test is unqualified. When the pressing block 1304 contacts with the card plate 1610, the slide The plate 1607 can move back in the slide groove 1402 under the action of the tension spring 1606, so that the slide plate 1607 is out of contact with the circuit board. At this time, the pressure block 1304 presses the card plate 1610 to approach the circuit board and stretch the spring 1611, so that the card plate 1610 squeezes the front and back sides of the circuit board. The card block 1609 can limit the card plate 1610 through the card slot to prevent the card plate 1610 from deflecting when moving. At the same time, the pressure block 1304 conducts longitudinal power supply to the circuit board through the card plate 1610. If the longitudinal circuit of the circuit board is a passage, the indicator light connected to the pressure rod 1303 lights up, and the longitudinal circuit detection is qualified. If the longitudinal circuit of the circuit board is a break, the indicator light connected to the pressure rod 1303 will not light up, and the longitudinal circuit detection is unqualified. When detecting the longitudinal circuit,Because the slide plate 1607 does not contact the circuit board, mutual interference during detection can be avoided. After all the detections are completed, the lifting rod 11 drives the pressure plate 12 to rise, and the pressure rod 1303 can drive the slide plate 1607 to move again through its own inclined surface to prevent the slide plate 1607 from getting stuck on the pressure rod 1303 and hindering the pressure plate 12 from rising. At the same time, the top spring 1603 drives the pad 1604 to reset, and pushes the circuit board out of the material trough 1602 to facilitate unloading. If the circuit board does not break after the pressure plate 12 rises, the circuit board passes the pressure test.

[0025] In summary, when using this automatic detection parts assembly machine, first place the circuit board mainboard on the left side of the chassis 1, and after the pushing rod 8 drives the clamping plate 9 to clamp the mainboard, the mechanical arm 10 can assemble the circuit board. After the assembly is completed, the pushing rod 8 drives the clamping plate 9 to release the clamping, and the telescopic rod 5 drives the pushing plate 6 to move to the right in the cavity 3, which can drive the pushing rod 7 to move to the right in the guide rail, and push the circuit board onto the pad 1604 and make it located in the center of the pad 1604. The lifting rod 11 drives the pressing plate 12 to descend, and the material is detected by the cooperation of the detection component 13 and the material placement component 16. When the pressing plate 12 descends, the slider 1403 can slide on the moving rod 1401 through the slide groove 1402 to prevent the moving rod 1401 from hindering the descent of the pressing plate 12. By keeping the connection between the movable plate and the fixed plate, when testing the circuit board, the pressing plate 12 can drive the bottom plate 1302 to descend, thereby driving the pressing plate 1307 to descend through the compression spring 1305, and applying pressure to the component to detect whether the component is firmly assembled. As the pressing plate 12 descends, the compression spring 1305 and the top spring 1603 are compressed, so that the circuit board enters the material placement groove 1602 until the contact 1306 contacts the connector 1308. If the component installation position is not offset, the pressing plate 1307 can remain horizontal so that the contact 1306 can be normally connected to the connector 1308, thereby energizing the indicator light above the contact 1306 to light up. If the component installation position is offset, the pressing plate 1307 will press the pressing spring 1305 during the compression process. 7 will be deflected, thereby causing the connector 1308 to be deflected, the contact 1306 cannot be connected to the connector 1308, and the indicator light is off. At this time, the component installation position can be detected whether it is deflected according to the on and off of the indicator light. At the same time, the pressing plate 1307 and the pad 1604 can cooperate with each other to apply pressure to the circuit board under the action of the compression spring 1305 and the top spring 1603, so as to detect the positive pressure resistance of the circuit board. The compression springs 1305 with different lengths can adapt to components of different sizes and heights, so as to ensure that the contact 1306 can contact the connector 1308 at the same time when the bottom plate 1302 descends, so as to avoid misjudgment caused by different contact times between the contact 1306 and the connector 1308. When the circuit board is subjected to a positive pressure resistance test, the pressing plate 12 can drive the pressure The rod 1303 and the pressure block 1304 descend synchronously, and the pressure rod 1303 first contacts the slide plate 1607, thereby pressing the slide plate 1607 to move in the slide groove 1402 through its own inclined surface and stretching the tension spring 1606, so that the slide plate 1607 squeezes the left and right sides of the circuit board. The slide groove 1402 can limit the slide plate 1607 to prevent the slide plate 1607 from deflecting when moving. At the same time, the pressure rod 1303 conducts longitudinal power to the circuit board through the slide plate 1607. If the longitudinal circuit of the circuit board is a passage, the indicator light connected to the pressure rod 1303 lights up, and the longitudinal circuit test is qualified. If the longitudinal circuit of the circuit board is a break, the indicator light connected to the pressure rod 1303 will not light up, and the longitudinal circuit test is unqualified. When the pressure block 1304 contacts the card plate 1610,The slide plate 1607 can be moved back in the slide groove 1402 under the action of the tension spring 1606, so that the slide plate 1607 is out of contact with the circuit board. At this time, the pressure block 1304 presses the card plate 1610 to approach the circuit board and stretch the spring 1611, so that the card plate 1610 squeezes the front and rear sides of the circuit board. The card block 1609 can limit the card plate 1610 through the card groove to prevent the card plate 1610 from deflecting when moving. At the same time, the pressure block 1304 conducts longitudinal power supply to the circuit board through the card plate 1610. If the longitudinal circuit of the circuit board is a passage, the indicator light connected to the pressure rod 1303 will light up, and the longitudinal circuit detection is qualified. If the longitudinal circuit of the circuit board is a break, the indicator light connected to the pressure rod 1303 will not light up, and the longitudinal circuit detection is unqualified. When detecting the longitudinal circuit, because the slide plate 1607 does not contact the circuit board, mutual interference during detection can be avoided. After all detections are completed, the lifting rod 11 drives the pressure plate 12 to rise, and the pressure rod 1303 can drive the slide plate 1607 to move again through its own inclined surface. The slide plate 1607 moves to prevent the pressing rod 1303 from being stuck and hindering the pressing plate 12 from rising. At the same time, the top spring 1603 drives the pad 1604 to reset, and the circuit board is pushed out of the material trough 1602 to facilitate unloading. If the circuit board is not broken after the pressing plate 12 rises, the circuit board is qualified in the pressure test. After the test is completed, the lifting rod 11 can drive the pressing plate 12 to rise. When the slider 1403 moves to the lower end of the slide groove 1402, the moving plate can drive the fixed plate to rise through the slider 1403. Thereby, the fixing pin 1405 is driven to slide on the base 1601, and then the base 1601 is driven to rotate in the placement slot 15. According to different detection results, the lifting rod 11 can drive the pressing plate 12 to rise by different distances, thereby driving the base 1601 to rotate at different angles in the placement slot 15 through the connecting component 14, so that the circuit board slides along the base 1601 with different inclinations to the corresponding material guide plate 17, thereby completing the sorting of the circuit boards, so as to facilitate the screening of unqualified products for rework.
