Abstract
Description
Technical Field
[0001] This application relates to the technical field of PCB board transfer devices, and in particular to a material transfer mechanism. Background Art
[0002] In the production of PCBs, the copper layer surface of the PCB will quickly undergo an oxidation reaction after coming into contact with air. Since the thickness of the copper layer in the PCB is very thin, the oxidized copper will become a poor conductor of electricity, which will greatly damage the electrical performance of the entire PCB.
[0003] In order to prevent copper oxidation, to separate the soldering part and the non-soldering part of the PCB during soldering, and to protect the surface layer of the PCB, ink is coated on the surface of the PCB to form a protective layer with a certain thickness on the PCB surface and block the contact between copper and air.
[0004] Since the miniLED circuit board is thinner and more brittle than the conventional circuit board, it needs to be carefully handled during the vertical ink coating process of the PCB board to reduce the generation of defective products during processing and improve the production yield. In the related art, the transport manipulator is movably arranged inside the processing rack. The material transport manipulator clamps the PCB board from the transfer end and transports it to the coating mechanism. The coating mechanism vertically pushes out the PCB board after coating from the coating mechanism, and transports it to the next processing area after being clamped by the material transport manipulator.
[0005] In the related art, the first clamping part of the clamping component for material transport is fixedly arranged, and the second clamping part is slidably arranged. The clamping action is completed by the sliding of the second clamping part. Since the clamping component needs to move to a preset position to accurately clamp the PCB board during the clamping process, the requirement for the positioning system is relatively high; since the first clamping block is fixedly arranged, when the PCB board is vertically pushed out of the coating mechanism after coating, if the PCB board is slightly tilted, the end of the PCB board is likely to collide with the first clamping block, resulting in mechanical damage to the clamped end of the PCB board. Summary of the Invention
[0006] In order to reduce the situation of collision between the manipulator and the PCB board during the clamping process of the PCB board and improve the qualified rate of finished products during the PCB coating process, this application provides a material transfer mechanism.
[0007] This application provides a material transfer mechanism, adopting the following technical solutions:
[0008] A material transfer mechanism includes a support base. On one side of the support base, there are two groups of clamping components. Each clamping component includes a guiding bar perpendicular to the support base. A sliding bar is slidably connected in the guiding bar along a direction perpendicular to the support base. On the support base, there is a first driving component for driving the sliding bar and the guiding bar to move in opposite directions. One first driving component is fixedly arranged on the support base, and the other first driving component is slidably arranged on the support base, and the sliding direction is perpendicular to the sliding direction of the sliding bar. An adjusting component is arranged on the support base for driving one of the first driving components to slide.
[0009] At one end of the guiding bar away from the support base, there is a first clamping piece. At one end of the sliding bar away from the support base, there is a second clamping piece. When the first driving component drives the sliding bar and the guiding bar to move towards each other, the first clamping piece can abut against the second clamping piece.
[0010] By adopting the above technical solution, the two groups of clamping components arranged in parallel on one side of the support base respectively clamp the two ends of the PCB board. The clamping component includes a guiding bar and a sliding bar slidably arranged in the guiding bar along the length direction of the guiding bar. At one end of the guiding bar, there is a first clamping piece, and at one end of the sliding bar, there is a second clamping piece. The first driving component is arranged on the support base and can drive the sliding bar and the guiding bar to move towards or away from each other simultaneously. When the first driving component drives the sliding bar and the guiding bar to move towards each other, the first clamping piece and the second clamping piece move towards each other to perform a clamping action. When the first driving part drives the sliding bar and the guiding bar to move away from each other, the first clamping piece and the second clamping piece gradually move away from the PCB board to loosen it.
[0011] When the material transfer mechanism moves to the position set by the positioning system, during the process that the first driving component drives the first driving mechanism to perform a clamping action, the first clamping piece and the second clamping piece move towards the PCB board at the same time, increasing the clamping range. Even if there is a deviation in the positioning of the positioning system or the end of the PCB board is tilted during the process of being pushed out of the coating mechanism, the clamping component is not likely to hit the PCB board, reducing the possibility of damage to the PCB board caused by the collision between the first clamping part or the second clamping part and the end of the PCB board. One first driving component is slidably arranged on the support base along a direction perpendicular to the sliding bar through the adjusting component. When the two clamping components clamp the PCB board, the sliding of the first driving component can drive the moving clamping component to move away from the other clamping component to adjust the flatness of the PCB board.
[0012] Optionally, the first driving component includes a parallel gripper. The parallel gripper includes a first driving part connected to one end of the guiding bar close to the support base and a second driving part connected to one end of the sliding bar close to the support base. The first driving part and the second driving part can move towards or away from each other.
[0013] By adopting the above technical solution, the parallel gripper includes a first driving part and a second driving part, and the first driving part is connected to the guiding bar, and the second driving part is connected to the sliding bar; when the first driving part and the second driving part move towards each other, they can indirectly drive the sliding bar and the guiding bar to move towards each other; when the first driving part and the second driving part move away from each other, they can indirectly drive the sliding bar and the guiding bar to move away from each other.
[0014] Optionally, the support base includes a bottom plate, and a fine adjustment sliding groove for one of the clamping assemblies to slide is formed on the bottom plate; the adjusting assembly is arranged on one side of the support base close to the fine adjustment sliding groove, and the adjusting assembly is used to drive the first driving assembly to slide along the fine adjustment sliding groove.
[0015] By adopting the above technical solution, a fine adjustment sliding groove is formed on the bottom plate for one of the clamping assemblies to slide, and the adjusting assembly is used to drive the first driving assembly to slide in a direction perpendicular to the guiding bar. When the first driving assembly slides, one of the clamping assemblies connected to the first driving assembly moves along the fine adjustment strip-shaped hole, so as to realize the adjustment of the distance between the two clamping assemblies; when the clamping assemblies clamp the two ends of the PCB board, the adjusting assembly drives the first driving assembly to move away from the other first driving assembly, so that the distance between the two clamping assemblies becomes larger, and the PCB board is tensioned to adjust the flatness of the PCB board.
[0016] Optionally, the support base includes a support table vertically fixed on the bottom plate, the adjusting assembly includes a pneumatic slide table, the pneumatic slide table includes a fixed base and a sliding part sliding on the fixed base, the fixed base is fixedly arranged on the support table, and the sliding part is fixedly connected to the first driving assembly.
[0017] By adopting the above technical solution, the support table vertically fixed on the bottom plate is used to fix the adjusting assembly, the fixed seat of the adjusting assembly is fixedly arranged on the support table, and the sliding part of the adjusting assembly is fixedly connected to the first driving assembly. When the sliding seat slides relative to the fixed seat, the first driving assembly is driven to slide in a direction perpendicular to the guiding bar.
[0018] Optionally, connecting bars are vertically and fixedly connected to the opposite ends of the two guiding bars, the connecting bars are located at the ends of the guiding bars far from the support base, a contact component is arranged on the connecting bars, the contact component includes a contact bar vertically sliding on the guiding bar, and a second driving assembly for driving the contact bar to move towards or away from the guiding bar is arranged on the connecting bars, and the contact bar is driven to move by the movement of the sliding bar.
[0019] By adopting the above technical solution, the connecting bar is used to connect the clamping assembly and the abutting assembly. When the first driving assembly drives the clamping assembly to clamp the PCB board, the sliding bar and the guiding bar drive the second driving assembly to move, so that the second driving assembly drives the two abutting bars to move towards each other until they abut against the side of the PCB board, providing a supporting force in the horizontal direction of the PCB board, thereby improving the movement stability of the PCB board during the transfer process by the transfer mechanism; under the action of the abutting bars, the shaking of the PCB board during the transfer process is reduced, thereby reducing the mechanical damage caused by the clamping assembly to the clamped end of the PCB board;
[0020] When the first driving assembly drives the clamping assembly to release the PCB board, when the sliding bar and the guiding bar drive the second driving assembly to drive the two abutting bars to move away from each other, the abutting bars move away from the PCB board. At the same time, the clamping assembly also releases the PCB board, so that the PCB board enters the next processing area.
[0021] Optionally, the second driving assembly includes a push-pull rod slidably disposed on the connecting bar. One end of the push-pull rod away from the first clamping member is provided with a jacket for clamping the abutting bar and allowing the abutting bar to slide vertically.
[0022] The second driving assembly further includes a driving member disposed on one side of the push-pull rod close to the guiding bar. The driving member is fixedly connected to the sliding bar and is used to drive the push-pull rod to move in a direction perpendicular to the length direction of the guiding bar.
[0023] By adopting the above technical solution, the first sliding groove opened on the connecting bar enables the abutting bar to slide towards or away from the guiding bar, so as to abut against the PCB board; a push-pull rod is provided at one end of the connecting bar close to the first clamping member, and the jacket at one end of the push-pull rod clamps the abutting bar. When the driving member drives the push-pull rod to move towards the guiding bar, the abutting bar clamped by the jacket is pulled to move towards the guiding bar to abut tightly against the PCB board.
[0024] Optionally, a guiding groove is opened at one end of the push-pull rod close to the driving member. The inner wall of the guiding groove includes a guiding surface that gradually inclines towards the sliding bar in the direction of the first clamping member; the driving member includes a driving bar that abuts against the guiding surface, and a reset member is disposed between the push-pull rod and the guiding bar.
[0025] By adopting the above technical solution, the guiding surface in the guiding groove on the push-pull rod is inclined gradually closer to the slider in the direction of the first clamping member, and the driving strip at the end of the slider close to the push-pull rod abuts against the guiding surface. When the slider and the guiding strip move towards each other for the clamping action, the driving strip on the slider moves in the direction close to the guiding groove, thereby pulling the push-pull rod towards the guiding strip, so that the pressing plate presses against the side of the PCB board; when the slider and the guiding strip move away from each other to release the PCB board, the driving strip gradually moves away from the guiding surface, and under the action of the reset member, the push-pull rod moves away from the guiding strip, so that the two abutting strips also release the PCB board.
[0026] Optionally, the connection is provided with a sliding groove for the abutting strip to move, the top of the abutting strip passes through the strip-shaped hole and is fixed with a limiting edge capable of abutting against the connecting strip, and an abutting strip is arranged at one end of the abutting strip away from the limiting edge, the abutting strip is arranged perpendicular to the length direction of the abutting strip and extends in the direction away from the guiding strip.
[0027] By adopting the above technical solution, the limiting edge of the abutting strip close to the jacket can abut against the connecting strip. On the one hand, the possibility of the abutting strip disengaging from the jacket is reduced. On the other hand, the jacket at one end of the push-pull rod is sleeved on the outer side wall of the abutting strip. When the driving strip drives the push-pull rod to move, the push-pull rod can move in the direction perpendicular to the guiding strip, and the limiting edge enables the side wall of the abutting strip to abut against the side wall of the sliding groove, so that the moving direction of the push-pull rod is not easily deflected; an abutting strip is arranged at one end of the pressing plate away from the limiting edge. When the material transfer mechanism holds the PCB board and descends, the abutting strip abuts against the frame, and the abutting strip moves vertically upward along the jacket, and most of it slides to the side of the connecting strip away from the push-pull rod, which is not easy to affect the movement of the support seat.
[0028] Optionally, the push-pull rod includes a fixed rod connected to the reset member, an adjusting rod threadedly connected to one end of the fixed rod, and a linkage rod rotatably connected to the end of the adjusting rod away from the fixed rod; the jacket is fixed to the end of the linkage rod away from the adjusting rod; the guiding groove is opened on the fixed rod.
[0029] By adopting the above technical solution, one end of the adjusting rod is threadedly connected to the inside of the fixed rod. By rotating the length of the adjusting rod connected to the inside of the fixed rod, the length of the push-pull rod can be adjusted to change the distance between the two abutting strips, and the distance between the two abutting strips can be finely adjusted, so as to accurately control the distance between the two abutting strips and the clamping assembly, so as to ensure that after the clamping assembly holds the PCB board, the pressing plate can lean against the side of the PCB board.
[0030] In summary, the present application includes at least one of the following beneficial effects: 1. The clamping mechanism includes a first clamping member disposed on the guiding bar and a second clamping member disposed on the sliding bar. The parallel gripper can simultaneously drive the guiding bar and the slider to move, so that the first clamping member and the second clamping member can move towards each other simultaneously to perform the clamping action, increasing the clamping range of the clamping assembly and reducing the mechanical damage caused to the PCB during the clamping process of the clamping assembly;
[0031] 2. A pneumatic slide is provided on the support base for driving a first driving component to move. When the pneumatic slide drives a first driving component to move, the clamping assembly connected to the first driving component moves away from the other clamping assembly to adjust the flatness of the PCB;
[0032] 3. An abutting assembly is provided on one side of the guiding bar. When the clamping assembly clamps the PCB, under the action of the second driving component, the abutting plate in the abutting assembly abuts against both sides of the PCB, improving the movement stability during the PCB transfer, thereby reducing the mechanical damage caused by the clamping assembly to the PCB.

[0038] The following is combined with the attached Figures 1-4A further detailed description of the present application is provided.
[0039] Embodiment 1:
[0040] A material transfer mechanism disclosed in an embodiment of the present application, referring to Figure 1 , a material transfer mechanism includes a support base 1. On one side of the support base 1, two sets of clamping components 2 are arranged in parallel, and the two clamping components 2 are spaced apart in the horizontal direction. The clamping component 2 includes a guide bar 21 and a slide bar 22 slidably arranged in the guide bar 21. The guide bar 21 is provided with a strip-shaped hole 211 along its length direction, and the slide bar 22 slides in the strip-shaped hole 211, which plays a role in reducing the occupied space of the clamping component 2. In this embodiment, two sets of crossed roller guides are arranged between the slide bar 22 and the guide bar 21. The two guide rails of the crossed roller guides are respectively fixed to the slide bar 22 and the guide bar 21, making the sliding between the slide bar 22 and the guide bar 21 smoother.
[0041] On the PCB production line, a lifting frame (not shown in the figure) moves along the PCB feeding direction. One end of the support base 1 is fixedly provided with a connecting plate, and a number of bolts are passed through the connecting plate. The connecting plate is used to fix the support base 1 on the lifting frame, and the material transfer mechanism moves along the vertical direction through the lifting frame; and by turning the bolts, the verticality of the support frame 1 can also be adjusted, so as to achieve the effect of adjusting the overall verticality of the material transfer mechanism.
[0042] Referring to Figure 1 , at one end of the guide bar 21 away from the support base 1, a first clamping member 212 is fixed, and at one end of the slide bar 22 away from the support base 1, a second clamping member 221 is fixed, and the first clamping component 2 and the second clamping member 221 are arranged in mirror symmetry; at one end of the clamping component 2 close to the support base 1, a first driving component is provided for controlling the opening and closing of the clamping component 2, that is, controlling the first clamping member 212 and the second clamping member 221 to move towards or away from each other; one end of a first driving component away from the clamping component 2 is fixed to the support base 1, and the other first driving component is slidably arranged on the support base 1.
[0043] Referring to Figure 1 , the first driving component includes a parallel gripper 3. The parallel gripper 3 includes a first driving part 31 and a second driving part 32 that are arranged in parallel and can move towards or away from each other. The first driving part 31 is fixedly connected to one end of the guide bar 21 close to the support base 1, and the second driving part 32 is fixedly connected to one end of the slide bar 22 close to the support base 1; when the first driving part 31 and the second driving part 32 move towards each other, the first clamping member 212 and the second clamping member 221 move towards each other to clamp the PCB board; when the first driving part 31 and the second driving part 32 move away from each other, the first clamping member 212 and the second clamping member 221 also move away from each other to release the PCB board.
[0044] Referring toFigure 1 The two sets of first driving components are connected to the same control system, enabling the two sets of first driving components to open and close simultaneously under the control of the control system; during the clamping operation of the clamping component 2, the guiding strip 21 and the sliding strip 22 move simultaneously, and the first clamping member 212 and the second clamping member 221 move towards each other, expanding the clamping range, thereby reducing the situation where the material transfer mechanism collides with the PCB board due to the deviation between the position where the PCB board is clamped and the preset position or the inclination of the end of the PCB board during the clamping process of the PCB board, and reducing the mechanical damage caused to the PCB board by the clamping component 2 during the clamping process.
[0045] Refer to Figure 2 As shown in the figure, the support base 1 includes a bottom plate 11. A fine-tuning sliding groove 12 for a clamping component 2 to slide horizontally is formed on the bottom plate 11. The first driving component slidably disposed on the support base 1 slides in the fine-tuning sliding groove 12 in a direction perpendicular to the guiding strip 21, and an adjusting component is provided on the first driving component. The adjusting component is specifically a pneumatic slide table 4, and the pneumatic slide table 4 includes a fixed base 41 and a sliding portion 42 slidably disposed on the fixed base 41; the support base 1 further includes a support table 13 fixedly disposed on the bottom plate 11. One end of the fixed base 41 is fixedly connected to the support table 13, and the sliding portion 42 is fixedly connected to the first driving component.
[0046] Refer to Figure 2 As shown in the figure, after driving the first driving component to clamp the PCB board with the two clamping components 2, drive the adjusting component to make the sliding portion 42 of the pneumatic slide table 4 slide slightly away from the fixed base 41, increasing the distance between the two clamping components 2, and slightly tensioning the PCB board with the two clamping components 2 to adjust the flatness of the PCB board.
[0047] The implementation principle of a material transfer mechanism in an embodiment of the present application is as follows:
[0048] When the PCB board is transported close to the clamping component 2, the control system controls the operation of the first driving component, driving the sliding strip 22 and the guiding strip 21 to move, so that the first clamping member 212 and the second clamping member 221 move towards each other to clamp the PCB board, and driving the pneumatic slide table 4 to make one first driving component slide slightly away from the other first driving component to adjust the flatness of the PCB board. Then the material transfer mechanism transports the PCB board to the coating system and then moves downward in the vertical direction to send the PCB board into the coating system; the first driving component drives the sliding strip 22 and the guiding strip 21 to move, driving the first clamping member 212 and the second clamping member to move away from each other to release the PCB board, and transferring the PCB board to the next processing area.
[0049] Embodiment 2:
[0050] The difference between this embodiment and Embodiment 1 is: Refer to Figure 3, one end of the guiding strip 21 close to the first clamping member 212 is provided with an abutting assembly 5. The abutting assembly 5 includes two abutting strips 51 respectively slidably arranged on the opposite sides of the two guiding strips 21; a connecting strip 53 is fixed on one side of the guiding strip 21 close to the abutting strip 51. The length direction of the connecting strip 53 is perpendicular to the length direction of the abutting strip 51. One end of the connecting strip 53 away from the guiding strip 21 is provided with a sliding groove 531 for the vertical sliding of the abutting strip 52, and the abutting strip 52 can slide within a certain range along the length direction of the connecting strip 53 in the sliding groove 531; one end of the guiding strip 21 is slidably provided with a second driving assembly for driving the abutting strip 51 to move along the length direction of the connecting strip 53.
[0051] Refer to Figure 3 and Figure 4 , the second driving assembly includes a push-pull rod 6 arranged along the length direction of the connecting strip 53. The push-pull rod 6 includes a clamping sleeve 631 at one end close to the abutting strip 51. Clamping grooves 511 are formed at both ends of the abutting strip 51 along the length direction of the abutting strip 52. The clamping sleeve 631 includes a clamping portion at one end close to the abutting strip 51, and the clamping portion is slidably arranged in the clamping groove 511.
[0052] Refer to Figure 4 , the second driving assembly further includes a driving member 65 fixedly arranged on the sliding strip 22. The driving member 65 includes a connecting portion 652 fixed on the sliding strip 22 and a driving strip 651 integrally formed with the connecting portion 652; a guiding groove 611 is formed at one end of the push-pull rod 6 close to the sliding strip 22, and the inner wall of the guiding groove 611 includes a guiding surface 6111. The guiding surface 6111 inclines towards the direction gradually approaching the sliding strip 22 in the direction close to the first clamping member 212; when the sliding of the sliding strip 22 and the guiding strip 21 drives the first clamping member 212 and the second clamping member 221 to move towards each other, the driving strip 651 abuts against the guiding surface 6111 of the guiding groove 611, driving the push-pull rod 6 to move towards the direction close to the guiding strip 21, thereby driving the abutting strip 51 to move towards the direction close to the guiding strip 21, so that the abutting strip 51 can abut against the side of the PCB board.
[0053] The abutting strip 52 is a counterweight strip. When the abutting strip 51 abuts against the side of the PCB board, the PCB board can slide up and down relative to the abutting strip 51, and at the same time, the abutting strip 51 can limit the shaking of the PCB board.
[0054] Refer to Figure 4, the push rod 6 includes a fixed rod 61, an adjusting rod 62, and a linkage rod 63 that are coaxially arranged at one end close to the guiding strip 21. A guiding groove 611 is formed in the fixed rod 61; the adjusting rod 62 includes a threaded section at one end close to the fixed rod 61, and the threaded section is threadedly connected to the inside of the fixed rod 61. One end of the adjusting rod 62 away from the fixed rod 61 is rotatably connected to the linkage rod 63 through a bearing; and a clamping sleeve 631 is fixedly arranged at one end of the linkage rod 63 away from the adjusting rod 62. When the adjusting rod 62 rotates, the length of the push rod 6 can be adjusted, so as to change the distance between the two abutting strips 51, so that the distance between the two abutting strips 51 can be finely adjusted according to the width of the PCB board.
[0055] Referring to Figure 4 , a reset member 64 is fixed at one end of the push rod 6 close to the guiding strip 21. In this embodiment, the reset member 64 is specifically a reset spring; when the sliding strip 22 and the guiding strip 21 move to drive the first clamping member 212 and the second clamping member 221 to move away from each other, the driving strip 651 gradually moves away from the guiding groove 611, and the push rod 6 gradually moves away from the guiding strip 21 under the action of the reset member 64, thereby driving the abutting strip 51 to move away from the guiding strip 21, so that the two abutting strips 51 can loosen the PCB board.
[0056] Referring to Figure 4 The abutting strip 51 can slide upward in the vertical direction along the clamping sleeve 631; a limiting edge 512 is fixed at the top of the abutting strip 51 close to the clamping sleeve 631. The limiting edge 512 and the clamping sleeve 631 are respectively located on both sides of the connecting strip 53. When the abutting strip 51 slides in the vertical direction, the limiting edge 512 can abut against the connecting strip 53, so that the abutting strip 51 is not easily detached from the clamping sleeve 631. By providing the limiting edge 512, when the support base 1 continues to rise after the limiting edge 512 abuts against the connecting strip 53, the abutting strip 51 can rise along with the connecting strip 53. When the support base 1 moves subsequently to transport the PCB board, the support base 1 can drive the abutting strip 51 to move together, so that the PCB board is not easily shaken.
[0057] Referring to Figure 3 and Figure 4 , a contact strip 52 is fixedly arranged at one end of the abutting strip 51 away from the limiting edge 512. The contact strip 52 is arranged perpendicular to the length direction of the abutting strip 51, and the two abutting strips 51 extend in opposite directions; when the material transfer mechanism transfers the PCB board and moves it to the coating system for coating, the contact strip 52 can abut against the frame. During the process of the support base 1 descending, the abutting strip 51 can move vertically upward relative to the support base 1 and does not easily affect the movement of the support base 1.
[0058] The implementation principle of a material transfer mechanism of the embodiment of the present application is as follows: when the PCB board is transported to near the clamping assembly 2, the control system controls the operation of the first drive assembly, drives the slide bar 22 and the guide bar 21 to move, so that the first clamping member 212 and the second clamping member 221 move toward each other to clamp the PCB board, and at the same time, the two abutting bars 51 located at the lower end of the connecting bar 53 abut against the PCB board; then the material transfer mechanism gradually rises, and the abutting bar 51 abuts against the connecting bar 53, so that the abutting bar 51 covers the entire side of the PCB board, thereby improving the stability of the PCB board during the transfer process, and continues to rise the support seat 1, and the connecting bar 53 drives the abutting bar 51 to rise together, so that the abutting bar 52 is separated from the rack for transporting the PCB board. The pneumatic slide 4 is driven to make one first drive assembly slide slightly in the direction away from the other first drive assembly to adjust the flatness of the PCB board.
[0059] Then the material transfer mechanism transports the PCB to the coating system, and then moves downward in the vertical direction to send the PCB into the coating system; the first drive assembly drives the slide bar 22 and the guide bar 21 to move, driving the first clamping member 212 to move away from the second clamping member to release the PCB; at the same time, the second drive assembly also drives the push-pull rod 6 to move away from the guide adjustment direction, so that the two clamping plates are away from the PCB. Similarly, after the PCB is coated, the PCB can be transferred to the next processing area through the material transfer mechanism.
[0060] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application.
[0061] Any equivalent changes made to the structure, shape, and principle should be included in the protection scope of this application.
