Description

Technical Field

[0001] This invention relates to the field of chip mounter technology, specifically a high-precision multi-axis linkage chip mounter based on dual-track parallelism and visual correction. Background Technology

[0002] To accommodate various sizes and specifications of PCB printed circuit boards and substrates to be mounted, and to improve the efficiency of continuous feeding operations, existing pick-and-place machines generally adopt a dual-track parallel conveyor structure to achieve continuous transport of printed circuit boards. They are equipped with a vision acquisition unit to collect real-time image information of the substrate position and posture, and complete on-track visual correction based on the visual imaging data. Combined with the multi-axis linkage mechanism of the whole machine, automated precision placement processing is achieved. The combination of dual-track conveyor and visual sampling correction has become the mainstream configuration of printed circuit board processing equipment.

[0003] In actual production, the conveyor track spacing needs to be flexibly adjusted according to different printed circuit board specifications to complete the printed circuit board conveying alignment and adaptation operation. During the track spacing adjustment process of conventional equipment, due to the large number of printed circuit board widths and thicknesses, the installation height and field of view of the vision camera need to be adjusted separately, making the operation process relatively complicated. After the track spacing is changed, the metal structure of the frame is prone to generating lateral diffuse reflection light and intruding into the vision acquisition area. At the same time, the substrates to be mounted with different printed circuit board thicknesses will change the vertical object distance between the board surface and the vision camera and the incident angle of the light path, which can easily cause uneven grayscale in vision imaging and fluctuations in the imaging contrast of the substrate edge. This will cause deviations in the substrate posture and position sampling data, thereby affecting the stability of the on-track correction response and the processing consistency of multi-axis mounting operations.

[0004] To address the aforementioned issues, innovative design based on existing methods is urgently needed. Summary of the Invention

[0005] The purpose of this invention is to provide a high-precision multi-axis linkage placement machine based on dual-track parallelism and visual correction to solve the problems mentioned in the background. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-precision multi-axis linkage placement machine based on dual-track parallelism and visual correction, comprising a placement machine body, a conveyor rail and a vision camera, wherein support frames are provided on both sides of the placement machine body, a support platform is installed on the upper end of the support frame, and an adjustment component is provided on the upper end of the support platform for adjusting the distance between the conveyor rail and the vision camera; The adjustment assembly includes a bidirectional cylinder installed at the lower end of the support frame. The output end of the bidirectional cylinder is connected to the lower end of the conveyor rail. The conveyor rail is slidably connected to the support platform. Lifting plates are installed on both sides of the conveyor rail, and the lifting plates are inclined. The support frame is vertically slidably connected to the lifting plates with an inverted concave frame, and the inverted concave frame has a lifting groove corresponding to the lifting plates. The vision camera is installed in the middle of the inverted concave frame. The upper end of the support frame is equipped with a reflective component, which is used to deflect the diffuse light path of the track.

[0007] Preferably, the reflective assembly includes a concave frame mounted on the upper end of the conveyor rail, a rotating shaft rotatably connected to the upper end of the concave frame, eccentric blocks mounted on both ends of the rotating shaft, and a force-bearing shaft mounted on one side of each eccentric block.

[0008] Preferably, a first adjusting plate is installed on the rotating shaft, and a second adjusting plate is rotatably connected to the side wall of the first adjusting plate. The second adjusting plate is a matte plate, and transmission grooves are provided at both ends of the first adjusting plate.

[0009] Preferably, the track is equipped with symmetrically arranged guide rods corresponding to the transmission groove, and the outer walls of the guide rods are slidably connected to a cross plate, with a boss integrally extending from the middle of the cross plate.

[0010] Preferably, the conveyor rail has a transmission hole corresponding to the boss, and a damping spring is connected to the lower end of the boss, the damping spring passing through the transmission hole.

[0011] Preferably, the lower end of the damping spring is connected to a collection plate, and the lower end of the collection plate is rotatably connected to several rollers. An actuating rod is installed on the collection plate corresponding to the hollow part of the damping spring. The actuating rod movably passes through the boss, and the actuating rod corresponds to the transmission groove.

[0012] Preferably, a T-shaped frame is installed on one side of the upper end of the cross plate, and the T-shaped frame has an extrusion groove, which is movably sleeved on the outer wall of the force-bearing shaft.

[0013] Preferably, the support frame is equipped with guard plates on both sides of the track, and the upper end of the guard plate naturally extends with a sloping pressure plate, which abuts against the side wall of the cross plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses a bidirectional cylinder to drive the conveyor rail to slide laterally, achieving dual-rail distance adjustment. Combined with the inclined transmission of the lifting plate and lifting groove, it drives the inverted bracket to move the vision camera synchronously up and down, matching the imaging field of view and framing height corresponding to different PCB printed circuit boards and substrates to be mounted, enabling the vision camera to clearly and stably acquire substrate position and posture image data. At the same time, the cross plate, together with the damping spring and the acquisition plate, forms a flexible vertical limiting structure, which elastically constrains the printed circuit board being transported on the rail, suppressing the offset, warping and shaking of the substrate during the transport process.

[0015] 2. This invention adopts a structural design that links the rotating shaft and the eccentric block to the first and second adjustment plates. The first adjustment plate gradually becomes steeper as the width of the conveyor rail increases, forming a V-shaped light-shielding layout that is wider at the top and narrower at the bottom together with the second adjustment plate. This layout synchronously blocks a large range of lateral diffuse stray light as the track gauge changes. The rotatably connected second adjustment plate can adaptively deflect relative to the first adjustment plate as the thickness of the printed circuit board changes. This matches the vertical object distance between the board surface and the vision camera, as well as the changes in the incident angle of the light path. First, the first adjustment plate is used to complete the coarse adjustment of the light path angle and build a basic light-shielding environment. Then, the second adjustment plate is used to achieve fine adjustment of the light path and adapt to the imaging requirements of different board thicknesses. With one coarse and one fine adjustment, one fixed and one moving, the grayscale of the visual imaging can be balanced and the contrast of the substrate edge imaging can be stabilized.

[0018] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0019] Please see Figures 1-9 The present invention provides a technical solution: a high-precision multi-axis linkage placement machine based on dual-track parallelism and visual correction, including a placement machine body 1, a conveyor rail 2 and a vision camera 3; Among them, the support frame 4 and the support platform 5 form an integral load-bearing structure, providing a stable installation benchmark for the sliding of the conveyor rail 2, the vertical sliding of the inverted bracket 603, and the overall reflective assembly, and ensuring the precision of the movement of components such as the bidirectional cylinder 601 and the lifting plate 602. In one embodiment of the present invention, the main body 1 of the pick and place machine is provided with support frames 4 on both sides, and a support table 5 is installed on the upper end of the support frame 4. An adjustment component is provided on the upper end of the support table 5 for adjusting the distance between the conveyor rail 2 and the vision camera 3. The adjustment component includes a bidirectional cylinder 601 installed at the lower end of the support frame 4. The output end of the bidirectional cylinder 601 is connected to the lower end of the conveyor rail 2. The conveyor rail 2 is slidably connected to the support table 5. Lifting plates 602 are installed on both sides of the conveyor rail 2, and the lifting plates 602 are inclined. The support frame 4 is vertically slidably connected to the lifting plates 602 with an inverted recess 603. The inverted recess 603 is provided with a lifting groove 604 corresponding to the lifting plates 602. The vision camera 3 is installed in the middle of the inverted recess 603. The track gauge is adjusted according to the specifications of the substrate to be bonded. A bidirectional cylinder 601 is activated, extending its output end to drive the two conveyor rails 2 on either side to slide towards or away from each other along the support platform 5. This adjusts the conveying width between the two rails, adapting to the on-rail conveying requirements of substrates of different specifications. While the conveyor rails 2 slide laterally to adjust the track gauge, they simultaneously drive the lifting plates 602 fixed to the side walls to move laterally. The inclined lifting plates 602 laterally press against the walls of the lifting grooves 604, driving the inverted frame 603 to slide vertically up and down along the support frame 4. During the lifting and lowering of the inverted frame 603, the vision camera 3 installed in the center moves up and down synchronously. The wider the track gauge, the greater the lifting height of the vision camera 3, and the wider the field of view for top-down imaging, effectively expanding the visual acquisition coverage area and reserving sufficient imaging field of view for subsequent on-rail visual correction. The inclined lifting plate 602 and the lifting groove 604 form an inclined transmission cooperation, which converts the lateral adjustment displacement of the conveyor rail 2 into the vertical lifting stroke of the inverted bracket 603, driving the vision camera 3 to rise and fall accordingly, matching the field of view height of different printed circuit board specifications.

[0020] In one embodiment of the present invention, a reflective component is provided on the upper end of the support frame 4 for deflecting the diffuse light path of the track. The reflective component includes a concave frame 701 installed on the upper end of the conveyor rail 2. A rotating shaft 702 is rotatably connected to the upper end of the concave frame 701. An eccentric block 703 is installed at both ends of the rotating shaft 702. A force-bearing shaft 704 is installed on one side of each eccentric block 703. A first adjusting plate 705 is installed on the rotating shaft 702. A second adjusting plate 706 is rotatably connected to the side wall of the first adjusting plate 705. The second adjusting plate 706 is a matte plate. A transmission groove 707 is provided at both ends of the first adjusting plate 705. A guide rod 708 is symmetrically arranged on the track corresponding to the transmission groove 707. A cross plate 709 is slidably connected to the outer wall of the guide rod 708. A boss 710 extends integrally from the middle of the cross plate 709. The conveyor rail 2 has a transmission hole corresponding to the boss 710. A damping spring 711 is connected to the lower end of the boss 710 and passes through the transmission hole. A collection plate 712 is connected to the lower end of the damping spring 711. Several rollers 713 are rotatably connected to the lower end of the collection plate 712. An action rod 714 is installed in the hollow part of the collection plate 712 corresponding to the damping spring 711. The action rod 714 moves through the boss 710 and corresponds to the transmission groove 707. A T-shaped frame 715 is installed on one side of the upper end of the cross plate 709. The T-shaped frame 715 has a pressing groove 716 and is movably sleeved on the outer wall of the force-bearing shaft 704. A guard plate 717 is installed on both sides of the support frame 4 corresponding to the rail. An inclined pressure plate 718 naturally extends from the upper end of the guard plate 717 and abuts against the side wall of the cross plate 709. When the track gauge of conveyor rail 2 is widened and it moves in opposite directions, the guide rod 708 and cross plate 709 on the side of the track move outward synchronously with the track gauge. During the lateral follow-up process, the cross plate 709 abuts against the side wall of the inclined pressure plate 718 at the upper end of the guard plate 717 and is limited. Under the pressure of the inclined surface of the pressure plate 718, the cross plate 709 slides vertically downward along the guide rod 708. The downward movement of the cross plate 709 drives the integrally formed boss 710 to move downward synchronously. The boss 710 presses down and compresses the damping spring 711 at the lower end. The damping spring 711 generates an elastic preload force, which forms a flexible downward pressure constraint on the substrate to be bonded on the conveyor rail 2 through the acquisition plate 712. The wider the track gauge, the greater the downward distance of the cross plate 709, and the greater the compression of the damping spring 711. The vertical limiting pressure force on the substrate to be bonded is simultaneously enhanced, effectively suppressing the offset and warping of the substrate during the conveying process. The swaying motion ensures the stability of the substrate's movement. As the cross plate 709 moves vertically downward, it drives the T-shaped frame 715 mounted on the side to move downward synchronously. The T-shaped frame 715 is movably fitted onto the outside of the force shaft 704 through the extrusion groove 716. The downward T-shaped frame 715 vertically extrudes the force shaft 704, forcing the force shaft 704 to drive the eccentric block 703 to deflect synchronously. The eccentric block 703 further drives the rotating shaft 702 to rotate on the upper end of the positive concave frame 701. During the rotation of the rotating shaft 702, it drives the fixed first adjusting plate 705 to swing synchronously. The first adjusting plate 705 then links with the second adjusting plate 706 hinged to the side wall to tilt synchronously. As the width of the conveyor rail 2 continues to increase, the tilt angle of the first adjusting plate 705 and the second adjusting plate 706 gradually becomes steeper, and the overall shape presents an outward expansion and contraction posture that is wider at the top and narrower at the bottom. The larger the track gauge, the wider the opening of the upper part of the figure-eight structure. Among them, the concave frame 701, the rotating shaft 702, the eccentric block 703 and the force-bearing shaft 704 cooperate to drive the first adjusting plate 705 and the second adjusting plate 706 to tilt synchronously with the change of the track gauge of the conveyor rail 2, forming a figure-eight light-blocking layout that is wider at the top and narrower at the bottom, which can effectively fold and block the lateral diffuse reflection light path of the frame. With the increased track gauge, the exposed area of ​​the metal frame on both sides of the track increases, making it easier for diffuse stray light to intrude into the central visual acquisition area. At this time, the first adjustment plate 705 and the second adjustment plate 706, which have steeper angles and are arranged with a wider top and narrower bottom, can deflect and guide the lateral diffuse light path outward, preventing stray light from directly entering the field of view of the visual camera 3, reducing background reflection interference, increasing the grayscale difference between the edge of the substrate to be attached and the background, and improving the imaging contrast. This is the first coarse adjustment of the optical path angle based on the change in track width. When substrates of different thicknesses are transported on the conveyor rail 2, the top surface of the substrate rolls into contact with the roller 713 at the lower end of the acquisition plate 712, realizing... The substrate is transported along with the substrate. The thicker the substrate, the higher the pushing stroke of the acquisition plate 712. The acquisition plate 712 overcomes the preload of the damping spring 711 and slides upward relative to the boss 710. At the same time, it drives the action rod 714 installed in the hollow position to pass through the boss 710 upward. The top of the action rod 714 extends into and abuts against the inner wall of the transmission groove 707 of the first adjustment plate 705. The action rod 714 continues to push the transmission groove 707, causing the first adjustment plate 705 to produce a small rotation angle. Relying on the rotational joint connection between the first adjustment plate 705 and the second adjustment plate 706, the second adjustment plate 706 is driven to self-adaptively deflect relative to the first adjustment plate 705 around its own hinge fulcrum, realizing independent angle fine adjustment. Among them, the printed circuit board substrate presses the acquisition plate 712 with roller 713, overcomes the elastic force of damping spring 711 to drive the action rod 714 to move vertically, pushes the transmission groove 707 of the first adjustment plate 705, and drives the second adjustment plate 706 to deflect around the hinge point, matching the vertical object distance and optical path incident tilt angle between the plate surface and the vision camera 3. The substrate thickness directly changes the vertical object distance between the substrate surface and the centrally located vision camera 3, thereby altering the light reflection path and the incident angle of the light path: the greater the substrate thickness, the higher the substrate position and the closer the vertical distance to the vision camera 3, the greater the oblique angle of the light path. Combined with the increased track gauge forming a wider top and narrower bottom V-shaped structure, the upper end further expands outward, and the second adjustment plate 706 synchronously rotates to finely adjust the tilt angle, guiding the large-angle oblique stray light from close range outward. The smaller the substrate thickness, the lower the substrate position and the farther the vertical distance to the vision camera 3, the gentler the incident angle of the light path. The second adjustment plate 706 then finely adjusts the tilt angle in the opposite direction, converging the peripheral diffuse reflection light path and compensating for insufficient light intake for long-distance imaging. This adapts to the differences in object distance and light path corresponding to different substrate thicknesses, completing the second fine adjustment of the light path angle based on the substrate thickness and matching the camera imaging distance.

[0021] Working principle: Adjust the track gauge according to the specifications of the substrate to be mounted, start the bidirectional cylinder 601, the output end of the bidirectional cylinder 601 extends and drives the two side conveyor rails 2 to slide in opposite directions or away from each other along the support platform 5, thereby adjusting the conveying width between the two rails to adapt to the on-rail conveying requirements of different specifications of substrates to be mounted.

[0022] While the conveyor rail 2 slides laterally to adjust the track gauge, it drives the lifting plate 602 fixed on the side wall to move laterally in sync. The inclined lifting plate 602 laterally presses against the wall of the lifting groove 604, driving the inverted frame 603 to slide vertically up and down along the support frame 4. During the lifting and lowering of the inverted frame 603, it drives the vision camera 3 installed in the middle to move up and down synchronously. The wider the track gauge, the greater the lifting height of the vision camera 3, and the field of view of the top-view imaging expands synchronously, effectively widening the visual acquisition coverage area and reserving sufficient imaging field of view for subsequent on-orbit visual correction.

[0023] When the track gauge of conveyor rail 2 is widened and moves in opposite directions, the guide rod 708 and cross plate 709 on the side of the track move outward synchronously with the track gauge. During the lateral follow-up process, the cross plate 709 abuts against the side wall of the inclined pressure plate 718 at the upper end of the guard plate 717 and is limited. Under the pressure of the inclined pressure plate 718, the cross plate 709 slides vertically downward along the guide rod 708. The downward movement of the cross plate 709 drives the integrally formed boss 710 to move downward synchronously. The boss 710 presses down and compresses the damping spring 711 at the lower end. The damping spring 711 generates an elastic preload force, which forms a flexible downward pressure constraint on the substrate to be attached on conveyor rail 2 through the acquisition plate 712. The wider the track gauge, the greater the downward distance of the cross plate 709, and the greater the compression of the damping spring 711. The vertical limiting pressure on the substrate to be attached is simultaneously enhanced, effectively suppressing the offset, warping and shaking of the substrate during the conveying process, and ensuring the stable movement of the substrate.

[0024] As the cross plate 709 moves vertically downward, it drives the T-shaped frame 715 mounted on the side to move downward synchronously. The T-shaped frame 715 is movably fitted onto the outside of the force shaft 704 through the extrusion groove 716. The downward T-shaped frame 715 vertically extrudes the force shaft 704, and the force shaft 704 is forced to drive the eccentric block 703 to deflect synchronously. The eccentric block 703 further drives the rotating shaft 702 to rotate on the upper end of the positive concave frame 701. During the rotation of the rotating shaft 702, it drives the first adjusting plate 705, which is fixed, to swing synchronously. The first adjusting plate 705 then links the second adjusting plate 706, which is hinged to the side wall, to tilt synchronously. As the width of the conveyor rail 2 continues to increase, the tilt angle of the first adjusting plate 705 and the second adjusting plate 706 gradually becomes steeper, and the whole presents an outward expansion and contraction posture that is wider at the top and narrower at the bottom. The larger the track gauge, the wider the opening of the upper part of the figure-eight structure.

[0025] As the track gauge increases, the exposed area of ​​the metal frame on both sides of the track increases, making it easier for diffuse stray light to intrude into the central visual acquisition area. At this time, the first adjustment plate 705 and the second adjustment plate 706, which are steeper in angle and arranged with a wider top and narrower bottom, can fold outward and guide the lateral diffuse light path to prevent stray light from directly entering the field of view of the visual camera 3, reduce background reflection interference, increase the gray value difference between the edge of the substrate to be attached and the background, and improve the imaging contrast. This is the first coarse adjustment of the light path angle based on the change of track width.

[0026] When substrates of different thicknesses are transported on the conveyor rail 2, the top surface of the substrate rolls into contact with the roller 713 at the lower end of the acquisition plate 712, thus achieving on-track transport. The greater the thickness of the substrate, the higher the pushing stroke of the acquisition plate 712. The acquisition plate 712 overcomes the preload of the damping spring 711 and slides upward relative to the boss 710, simultaneously driving the action rod 714 installed in the hollow position to pass through the boss 710 upward, so that the top end of the action rod 714 extends into and abuts against the inner wall of the transmission groove 707 of the first adjustment plate 705. The action rod 714 continues to push the transmission groove 707, causing the first adjustment plate 705 to produce a small angle. Relying on the rotating joint connection between the first adjustment plate 705 and the second adjustment plate 706, the second adjustment plate 706 is driven to self-adaptively deflect relative to the first adjustment plate 705 around its own hinge fulcrum, thus achieving independent angle fine adjustment.

[0027] The substrate thickness directly changes the vertical object distance between the substrate surface and the centrally located vision camera 3, thereby altering the light reflection path and the incident angle of the light path: the greater the substrate thickness, the higher the substrate position and the closer the vertical distance to the vision camera 3, the greater the oblique angle of the light path. Combined with the increased track gauge forming a wider top and narrower bottom V-shaped structure, the upper end further expands outward, and the second adjustment plate 706 synchronously rotates to finely adjust the tilt angle, guiding the large-angle oblique stray light from close range outward. The smaller the substrate thickness, the lower the substrate position and the farther the vertical distance to the vision camera 3, the gentler the incident angle of the light path. The second adjustment plate 706 then finely adjusts the tilt angle in the opposite direction, converging the peripheral diffuse reflection light path and compensating for insufficient light intake for long-distance imaging. This adapts to the differences in object distance and light path corresponding to different substrate thicknesses, completing the second fine adjustment of the light path angle based on the substrate thickness and matching the camera imaging distance.
