Description

Technical Field

[0001] The utility model relates to the field of electrical measurement and detection facilities, in particular to electrical automation positioning and detection equipment. Background Art

[0002] In the field of electrical automation testing, especially during the production of electronic components such as printed circuit boards (PCBs), workpieces on conveyor belts must be tested for electrical properties such as continuity, short circuits, and component soldering quality to ensure product compliance with design standards and promptly detect production defects such as cold solder joints, open circuits, and misinstalled components. Traditional testing equipment often uses fixed inspection stations, requiring inspection after the workpieces, which are continuously transported on the conveyor belt, stop. Alternatively, the workpieces must be removed from the conveyor belt for manual contact inspection. This method results in low conveying and inspection efficiency. Furthermore, due to high-speed movement or multi-station transmission of workpieces on the conveyor belt, they are prone to positional displacement due to factors such as vibration and conveyor belt deviation. This prevents precise alignment between the detection contacts and the workpiece test points, necessitating centering before testing. Existing centering restraint devices are often configured as fixed structures such as side guards and guide rollers, which have limited effectiveness in guiding the workpiece centering. Especially when workpiece sizes vary, adaptive adjustment of the restraint range is difficult, increasing manual calibration costs before testing. Utility Model Content

[0003] The purpose of this utility model is to provide an electrical automation positioning detection device in order to solve the above problems, which solves the technical problems such as synchronous detection accuracy, workpiece position constraint and dynamic adjustment of detection part in high-speed transportation scenarios, and provides an efficient and stable solution for electrical automation detection. Please see the following for details.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] The utility model provides an electric automatic positioning detection device, comprising a frame, a conveyor belt and a sliding seat, wherein the conveyor belt is arranged inside the frame, the sliding seat is arranged above the frame, a detection part is arranged on the bottom side of the sliding seat, and a side frame is fixed on the top side of the frame to support the sliding seat and drive the detection part to slide laterally, synchronous belts are arranged on the front and rear sides of the side frame, and two sets of transmission assemblies arranged on the front and rear opposite sides are arranged on the outside of the side frame, and the transmission assembly is used to keep the synchronous belt and the conveyor belt rotating synchronously;

[0006] The front and rear sides of the sliding seat are provided with vertically arranged upper clamping blocks and lower clamping blocks, and the synchronous belt extends horizontally between the upper clamping block and the lower clamping block. A vertically movable clamping plate is provided inside the sliding seat, and the front and rear ends of the clamping plate are respectively inserted into two groups of the synchronous belts, and an electric cylinder that drives the clamping plate to slide vertically is fixed on the top side of the sliding seat. The clamping plate moves up and forms a forward clamping mechanism with the upper clamping block to drive the sliding seat forward, and the clamping plate moves down and forms a reverse clamping mechanism with the lower clamping block to drive the sliding seat backward.

[0007] The above-mentioned electrical automation positioning detection equipment is used. When in use, the circuit board to be tested is sent onto the conveyor belt from one end of the conveyor belt close to the driving motor, and is discharged from the conveyor belt along the conveyor belt away from the driving motor. The travel direction of the circuit board to be tested is set to be forward. When the circuit board to be tested moves between the two sets of constraint components under the support of the conveyor belt, the servo motor drives the screw to rotate, and uses the two sets of external threads with opposite rotation directions at both ends of the screw to drive the two sets of support arms to approach each other through the rotation of the screw under the action of the external threads and the threads of the support arms. At this time, the push spring at the bottom end of the support arm drives the transmission gear disc to move horizontally in the direction close to the active gear disc. Since the active gear disc rotates with the roller shaft driven by the driving motor, when the transmission gear disc is pressed to the outside of the active gear disc by the push spring at the bottom end of the support arm, the transmission rod realizes the transmission connection with the roller shaft through the transmission shaft and the transmission gear disc. At this time, the synchronous wheel in the outer side frame rotates synchronously with the roller shaft, thereby driving the external synchronous belt and the conveyor belt to rotate synchronously;

[0008] After that, the two sets of arms continue to move closer under the drive of the screw. After the transmission connection between the roller shaft and the transmission shaft is completed, the arms continue to drive the two sets of constraint components closer to each other. Then, the fixed plates of the two sets of constraint components cooperate with the constraint rollers to adjust the position of the circuit board to be tested on the conveyor belt, so that it is placed in the center for subsequent fitting and testing.

[0009] When it is necessary to keep the sliding seat driving the detection part and the circuit board to be tested to slide in the positive direction and synchronously, that is, when it is necessary to keep the detection part and the circuit board to be tested in a relatively static state in the horizontal direction, the electric cylinder is contracted to pull the lower clamping plate upward, and the upper half of the synchronous belt is pressed against the bottom side of the upper clamping block by the clamping plate, so as to transmit the synchronous belt and the sliding seat through the positive clamping mechanism. At this time, the sliding seat follows the upper half of the synchronous belt to slide in the positive direction, thereby keeping the circuit board to be tested, the sliding seat and the detection part relatively static in the horizontal direction during the process of the circuit board to be tested being transported laterally by the conveyor belt. Then, the detection part is driven downward by the electric push rod, and the detection contact of the detection part is brought into contact with the test contact on the top of the circuit board to be tested, thereby realizing the traveling detection of the circuit board to be tested during the conveying process.

[0010] When the inspection of the previous group of circuit boards to be tested is completed and the sliding seat needs to drive the detection part to move to the position of the next group of circuit boards to be tested, the electric cylinder drives the clamping plate to move down to the position against the lower half of the synchronous belt, so as to connect the synchronous belt and the sliding seat through the reverse clamping mechanism composed of the clamping plate and the lower clamping block. At this time, the sliding seat follows the lower half of the synchronous belt to slide in the opposite direction, thereby realizing the reverse movement of the sliding seat and the circuit boards to be tested, so as to adjust the lateral relative positions of the sliding seat and the detection part to the circuit boards to be tested, thereby completing the detection actions one by one while the conveyor belt continues to transport the circuit boards to be tested in the forward direction by alternating the positions of the sliding seat and the detection part in the horizontal direction.

[0011] Preferably, the frame includes a bottom frame placed flat on the ground, with rotating seats vertically fixed on both sides of the bottom frame, a roller shaft supporting the rotation of the conveyor belt is provided on the top of the rotating seat, and active gear discs are fixed at both ends of the roller shaft corresponding to the transmission assembly, a pulley is provided between the active gear disc and the end face of the roller shaft, a driving motor for driving the conveyor belt to rotate is provided on the outside of the frame, and a driving belt is connected to the pulley and the output end of the driving motor.

[0012] Preferably, the side frame includes two groups of side frames fixed to the outside of the rotating seat, and the two groups of side frames are laterally connected with a sliding rod serving as a lateral sliding guide mechanism of the sliding seat. The front and rear sides of the side frames are both rotatably provided with synchronous wheels corresponding to the end faces of the roller shafts. A transmission groove with a regular polygonal through-groove structure is longitudinally penetrated by the center of the synchronous wheel, and a longitudinally extending sliding frame is vertically penetrated by the top of the side frame.

[0013] Preferably, the transmission assembly includes a transmission rod that penetrates longitudinally and slidably fits into the transmission groove, and a longitudinally extending transmission shaft is fixed to one end of the transmission rod that extends into the side frame, and a transmission sprocket that can detachably engage with the active sprocket is fixed to one end of the transmission shaft away from the transmission rod, and both the active sprocket and the transmission sprocket are helical gear ring structures.

[0014] Preferably, a support arm is provided on the outside of the transmission rod, and an axial hole with a clearance fit for the transmission rod is provided at the bottom end of the support arm, and the transmission rod is clearance fit with the axial hole, and the top end of the support arm vertically extends into the interior of the sliding frame and slides longitudinally with the sliding frame, and a spring is provided on the outside of the transmission rod between the support arm and the transmission gear disc, and the spring is used to keep the support arm in a tight supporting state against the transmission gear disc.

[0015] Preferably, a drive assembly is provided on the top of the side frame, and the drive assembly includes a servo motor fixed to the outside of the side frame. The output end of the servo motor extends longitudinally into the sliding frame and is connected to a screw for transmission. Two sets of external threads with opposite rotation directions are provided at both ends of the screw, and the screw is respectively matched with the two sets of support arm threads through the two sets of external threads.

[0016] Preferably, a constraint assembly is provided on opposite sides of the two groups of support arms, and the constraint assembly includes a fixed plate fixed transversely to the inner side of the support arm, and the outer end portions of the two groups of fixed plates extend outwardly and tilted to form a flared guiding mechanism, which is used to guide the objects to be tested to converge to the middle of the conveyor belt, and an installation frame is connected to the inner side of the fixed plate, in which a plurality of transversely arranged constraint rollers are rotatably provided.

[0017] Preferably, an electric push rod supporting the lifting and lowering movement of the detection part is fixed on the top side of the sliding seat, and a sliding ear slidingly adapted to the sliding rod is fixed on the outer side of the sliding seat, and the upper and lower sides of the front and rear ends of the clamping plate are provided with tooth-groove structure clamping grooves, which are used to increase the clamping and holding force of the clamping plate on the synchronous belt.

[0018] The beneficial effects are as follows: 1. The utility model realizes the forward and reverse clamping transmission of the synchronous belt by driving the clamping plate with the upper and lower clamping blocks through the electric cylinder. The tooth grooves of the clamping plate and the synchronous belt are tightly engaged, ensuring that the lateral displacement of the detection part and the workpiece are synchronized and the test points are aligned.

The detection part 5 is an electrical function test structure with a test contact, and the detection part 5 is a prior art in this field, which is used for contact-type power-on detection of the electrical performance of the circuit board to be tested, and will not be repeated here, and a side frame 3 is fixed on the top side of the frame 1 to support the sliding seat 4 and drive the detection part 5 to slide laterally, and a synchronous belt 12 is arranged on the front and rear sides of the side frame 3, and two groups of transmission components 6 arranged on the front and rear opposite sides are arranged on the outside of the side frame 3, and the transmission component 6 is used to keep the synchronous belt 12 and the conveyor belt 2 rotating synchronously;

[0037] The front and rear sides of the sliding seat 4 are both provided with vertically arranged upper clamping blocks 403 and lower clamping blocks 404, and the synchronous belt 12 extends horizontally between the upper clamping blocks 403 and the lower clamping blocks 404. A vertically movable splint 10 is provided inside the sliding seat 4, and the front and rear ends of the splint 10 are respectively inserted into two sets of synchronous belts 12, and an electric cylinder 11 is fixed on the top side of the sliding seat 4 to drive the splint 10 to slide vertically. The splint 10 moves upward and forms a forward clamping mechanism with the upper clamping block 403 to drive the sliding seat 4 forward, and the splint 10 moves downward and forms a reverse clamping mechanism with the lower clamping block 404 to drive the sliding seat 4 backward.

[0038] As an optional embodiment, the frame 1 includes a bottom frame 101 placed horizontally on the ground, and a rotating seat 102 is vertically fixed on both sides of the bottom frame 101. A roller shaft 103 that supports the rotation of the conveyor belt 2 is provided at the top of the rotating seat 102, and a driving gear disc 104 is fixed to the corresponding transmission assembly 6 at both ends of the roller shaft 103. A pulley 103a is provided between the driving gear disc 104 and the end face of the roller shaft 103. A driving motor 9 for driving the conveyor belt 2 to rotate is provided on the outside of the frame 1, and a driving belt 105 is connected to the output end of the driving motor 9. With this arrangement, the pulley 103a is driven to rotate by the driving motor 9 via the driving belt 105, and then the roller shaft 103 is driven to rotate, thereby realizing stable transmission of the conveyor belt 2 to the circuit board to be tested;

[0039] The side frame 3 includes two groups of side frames 301 fixed to the outside of the rotating base 102. A sliding rod 302 serving as a lateral sliding guide mechanism for the sliding base 4 is laterally connected between the two groups of side frames 301 to provide a stable guide for the lateral sliding of the sliding base 4 to ensure the straightness of the detection part 5 during translation. Synchronous wheels 303 corresponding to the end faces of the roller shaft 103 are rotatably provided on the front and rear sides of the side frames 301. A transmission groove 303a with a regular polygonal through-groove structure is longitudinally penetrated by the center of the synchronous wheel 303, and a longitudinally extending sliding frame 304 is vertically penetrated by the top of the side frame 301. With this arrangement, torque transmission can be achieved through the polygonal cooperation of the transmission groove 303a and the transmission rod 601, and the sliding frame 304 provides a guide for the longitudinal movement of the support arm 604.

[0040] The transmission assembly 6 includes a transmission rod 601 that penetrates longitudinally and slidably adapts to the transmission groove 303a, ensuring that the transmission rod 601 can generate axial sliding in the transmission groove 303a, and can drive the synchronous wheel 303 to rotate through the rotation of the transmission rod 601 to realize torque transmission. The transmission rod 601 extends into the side frame 301 and is fixed with a longitudinally extending transmission shaft 602 at one end. The transmission shaft 602 is fixed with a transmission gear disc 603 that can detachably engage with the active gear disc 104 at one end away from the transmission rod 601, which is used to transmit the rotational torque of the roller shaft 103 to the synchronous wheel 303, so as to achieve speed matching between the synchronous belt 12 and the conveyor belt 2. The active gear disc 104 and the transmission gear disc 603 are both helical gear ring structures. Such an arrangement can enhance the meshing tightness through the axial component of the helical tooth surface, reduce the impact force during transmission engagement, and improve transmission stability;

[0041] A support arm 604 is provided on the outside of the transmission rod 601, and an axial hole with a clearance fit for the transmission rod 601 is provided at the bottom end of the support arm 604, and the transmission rod 601 is clearance-fitted with the axial hole to allow the transmission rod 601 and the transmission shaft 602 to slide axially relative to the support arm 604. The top end of the support arm 604 vertically extends into the interior of the slide frame 304 and slides longitudinally with the slide frame 304. A spring 602a is sleeved on the outside of the transmission rod 601 between the support arm 604 and the transmission gear disc 603. The spring 602a is used to maintain the support arm 604 in a tight support state against the transmission gear disc 603, and is used to ensure reliable engagement of the transmission gear disc 603 with the active gear disc 104 through elastic preload force, and compensate for the assembly clearance. Such a configuration facilitates maintaining the continuity of the transmission connection during the movement of the support arm 604;

[0042] A drive assembly 7 is provided on the top of the side frame 3. The drive assembly 7 includes a servo motor 701 fixed to the outside of the side frame 301. The output end of the servo motor 701 extends longitudinally into the sliding frame 304 and is transmission-connected to a screw rod 702. Two sets of external threads 702a with opposite rotation directions are provided at both ends of the screw rod 702. The screw rod 702 is respectively threadedly engaged with the two sets of support arms 604 through the two sets of external threads 702a. The servo motor 701 drives the screw rod 702 to rotate, and the reverse threads are used to drive the two sets of support arms 604 to move closer or farther synchronously, thereby achieving width adjustment of the constraint assembly 8.

[0043] A constraint assembly 8 is provided on opposite sides of the two sets of support arms 604. The constraint assembly 8 includes a fixing plate 801 fixed laterally to the inner side of the support arm 604. The outer ends of the two sets of fixing plates 801 extend outwardly at an angle to form a flared guide mechanism for guiding the objects to be measured to converge toward the middle of the conveyor belt 2. A mounting frame 802 is connected to the inner side of the fixing plates 801. A plurality of laterally arranged constraint rollers 803 are rotatably provided in the mounting frame 802. The constraint rollers 803 are used to reduce friction through rolling contact during the conveyance of the workpiece, thereby avoiding scratching the workpiece surface and maintaining lateral constraint on the workpiece.

[0044] An electric push rod 401 supporting the lifting and moving of the detection part 5 is fixed on the top side of the sliding seat 4, which is used to drive the detection part 5 to lift and lower, so as to achieve precise contact or separation between the detection contact and the test point of the workpiece, and a sliding ear 402 that slides to adapt to the slide rod 302 is fixed on the outside of the sliding seat 4, which is used to cooperate with the slide rod 302 to limit the freedom of the sliding seat 4 and ensure stability during lateral sliding. The upper and lower sides of the front and rear ends of the splint 10 are provided with a tooth-groove structure clamping groove 10a, which is used to increase the clamping and holding force of the splint 10 on the synchronous belt 12.

[0045] The above-mentioned electrical automation positioning detection equipment is used. When in use, the circuit board to be tested is sent onto the conveyor belt 2 from the end of the conveyor belt 2 close to the drive motor 9 and discharged from the conveyor belt 2 along the end of the conveyor belt 2 away from the drive motor 9. The moving direction of the circuit board to be tested is set to be forward. When the circuit board to be tested moves between the two sets of constraint components 8 under the support of the conveyor belt 2, the servo motor 701 drives the screw 702 to rotate. The two sets of external threads 702a with opposite rotation directions at both ends of the screw 702 are used. Under the action of the external threads 702a and the threads of the support arms 604, the screw 702 rotates to drive the two sets of support arms 604. 4 are close to each other, and at this time, the transmission gear disc 603 is driven to move in a direction close to the active gear disc 104 by the push spring 602a at the bottom end of the support arm 604. Since the active gear disc 104 rotates following the roller shaft 103 under the drive of the drive motor 9, when the transmission gear disc 603 is pressed to the outside of the active gear disc 104 by the push spring 602a at the bottom end of the support arm 604, the transmission rod 601 is connected to the roller shaft 103 through the transmission shaft 602 and the transmission gear disc 603. At this time, the synchronous wheel 303 in the outer side frame 3 rotates synchronously with the roller shaft 103, thereby driving the external synchronous belt 12 to rotate synchronously with the conveyor belt 2;

[0046] Afterwards, the two sets of support arms 604 continue to move closer together under the drive of the screw 702. After the transmission connection between the roller shaft 103 and the transmission shaft 602 is completed, the support arms 604 continue to drive the two sets of constraint assemblies 8 closer together. Then, the fixed plates 801 of the two sets of constraint assemblies 8 cooperate with the constraint rollers 803 to adjust the position of the circuit board to be tested on the conveyor belt 2 so that it is placed in the center for subsequent fitting and testing.

[0047] When it is necessary to keep the sliding seat 4 driving the detection part 5 and the circuit board to be tested to slide in the positive direction and synchronously, that is, when it is necessary to keep the detection part 5 and the circuit board to be tested in a relatively static state in the horizontal direction, the electric cylinder 11 is contracted to pull the lower clamping plate 10 upward, and the clamping plate 10 presses the upper half of the synchronous belt 12 to the bottom side of the upper clamping block 403, so as to transmit the synchronous belt 12 and the sliding seat 4 through the positive clamping mechanism. At this time, the sliding seat 4 follows the upper half of the synchronous belt 12 to slide in the positive direction, so that the circuit board to be tested, the sliding seat 4 and the detection part 5 are kept relatively static in the horizontal direction during the process of the circuit board to be tested being transported horizontally by the conveyor belt 2. Then, the detection part 5 is driven downward by the electric push rod 401, and the detection contact of the detection part 5 is brought into contact with the test contact on the top of the circuit board to be tested, so as to realize the traveling detection of the circuit board to be tested during the transportation process;

[0048] When the inspection of the previous group of circuit boards to be tested is completed and the sliding seat 4 needs to drive the detection part 5 to move to the position of the next group of circuit boards to be tested, the electric cylinder 11 drives the clamping plate 10 to move down to the position close to the lower half of the synchronous belt 12, so as to transmit the synchronous belt 12 to the sliding seat 4 through the reverse clamping mechanism composed of the clamping plate 10 and the lower clamping block 404. At this time, the sliding seat 4 follows the lower half of the synchronous belt 12 to slide in the opposite direction, thereby realizing the reverse movement of the sliding seat 4 and the traveling direction of the circuit boards to be tested, so as to adjust the lateral relative positions of the sliding seat 4 and the detection part 5 to the circuit boards to be tested, thereby completing the detection action one by one while the conveyor belt 2 continues to transport the circuit boards to be tested in the forward direction by alternating the positions of the sliding seat 4 and the detection part 5 in the horizontal direction;

[0049] The utility model drives the clamping plate 10 through the electric cylinder 11, and cooperates with the upper and lower clamping blocks 404 to realize the forward and reverse clamping transmission of the synchronous belt 12. The tooth grooves of the clamping plate 10 are tightly engaged with the synchronous belt 12, ensuring that the detection part 5 and the lateral displacement of the workpiece are synchronized and the test points are aligned. The lower half of the clamping synchronous belt 12 can be quickly reset in the reverse direction without the need for additional power, simplifying the equipment structure and improving the transmission efficiency and stability.

[0050] The flaring fixing plate 801 and the multi-constraint roller 803 of the constraint assembly 8 are moved closer or further away by the support arm 604 driven by the screw 702, which can adapt to workpieces of different widths. Through the flaring guidance and real-time adjustment of the multi-roller, the workpiece is automatically centered, reducing the manual calibration process and improving the consistency of detection. The transmission assembly 6 adopts helical tooth meshing and spring 602a pre-tightening to ensure that the helical teeth are tightly meshed, ensuring that the constraint assembly 8 and the conveyor belt 2 are synchronized in speed, avoiding workpiece deviation, and enhancing detection accuracy.

[0051] The detection part 5 is driven to rise and fall by the electric push rod 401, and the sliding ear 402 adapts to the slide bar 302 to achieve lateral guidance, thereby realizing dynamic lateral and longitudinal adjustment. The lifting action of the detection part 5 does not conflict with the lateral conveying action of the circuit board to be tested, and plays a role in avoiding damage at the moment when the contact contacts the workpiece, thereby realizing the moving detection of the workpiece to be tested and flexibly responding to the detection needs of multiple scenarios.
