Description

Technical Field

[0001] The utility model belongs to the technical field of equipment for circuit board production, and particularly relates to a circuit board implanting machine for implanting a circuit board into a jig. Background Art

[0002] In the process of circuit board production, sometimes it is necessary to place the circuit board on a jig for the next operation. There is a current jig including a carrier plate and a cover plate. The circuit board needs to be implanted into the carrier plate and then the cover plate is covered, that is, it is clamped between the carrier plate and the cover plate. When the jig is fed, the carrier plate is provided with the cover plate. Thus, it is necessary to remove the cover plate from the carrier plate, implant the circuit board, then cover the cover plate, and then the carrier plate with the implanted circuit board is received by the material receiving mechanism. In addition, the circuit board to be implanted may need to be turned over before being implanted into the carrier plate. For these operations, in the existing equipment, generally, there are a handling mechanism for transferring the cover plate, a handling mechanism for transferring the circuit board, a conveying mechanism for the jig, a conveying mechanism for the circuit board, a turning mechanism, etc. arranged dispersedly. Therefore, the structure of the equipment is complex, the body is huge, the stroke of the handling mechanism is long, and the working efficiency is low. Summary of the Invention

[0003] Aiming at the problems existing in the prior art, the main purpose of the utility model is to provide a circuit board implanting machine for implanting a circuit board between a carrier plate and a cover plate, which has a compact structure and high production efficiency.

[0004] To achieve the above main purpose, the utility model provides a circuit board implanting machine for implanting a circuit board into a jig. The implanting machine includes a frame, on which a jig conveying device, a circuit board supply device, a handling device and a turning device are installed. The handling device includes an X-axis moving module and a Y-axis moving module moving in the horizontal direction, a Z-axis moving module moving in the vertical direction and a grasping mechanism. The grasping mechanism can move in the X-axis, Y-axis and Z-axis directions. The first moving track guiding the Y-axis moving module is respectively arranged at the tops of the side frames on both sides. The second moving track guiding the X-axis moving module is a part of the Y-axis moving module, and both ends of the second moving track are respectively supported on the first moving track. A translation component that can move between a first position and a second position is arranged in the jig conveying device, and the conveying direction of the jig conveying device is parallel to the X-axis direction. The turning device includes a rotatable receiving plate, a supporting mechanism and a rotation driving mechanism, and a moving driving mechanism for moving the receiving plate in the vertical direction. The supporting mechanism is arranged across the jig conveying device to support the receiving plate above the jig conveying device. When the receiving plate is horizontally arranged, at least part of the projection in the vertical direction covers the second position. The circuit board supply device has a circuit board placing position, and the handling device grasps the circuit board located at the circuit board placing position.

[0005] As can be seen from the above solution, the first moving track is arranged on both sides of the frame, and the second moving track spans the entire width of the frame, enabling the grasping mechanism of the handling device to move basically within the space range of the entire board planting machine, and it can grasp products at any position within the board planting machine. Therefore, only one handling device can be set to complete the implantation of the circuit board into the fixture, resulting in a relatively simple structure of the board planting machine. In addition, arranging the translation assembly inside the fixture conveying device can save space. The supporting mechanism of the turning device spans the fixture conveying device and supports the receiving plate above the fixture conveying device, enabling the circuit board turning operation to be carried out above the fixture conveying device without occupying additional space. Thus, the board planting machine has a simple structure, a compact layout, a short stroke during the operation of the handling device, and high production efficiency.

[0006] According to a specific embodiment of the present invention, the circuit board supply device is further provided with a collection position. The circuit boards are placed in trays or separator papers. After all the circuit boards thereon are grasped by the handling device, the circuit board supply device moves the empty trays or separator papers from the circuit board placement position to the collection position, and moves the trays or separator papers with circuit boards placed below the original trays or separator papers upward to the circuit board placement position; the moving direction of the empty trays or separator papers from the circuit board placement position to the collection position is parallel to the X-axis direction.

[0007] As can be seen from the above solution, through the circuit board supply device, automatic supply of circuit boards and automatic collection of circuit board loading utensils can be realized, and the degree of automation of the board planting machine is high.

[0008] According to a specific embodiment of the present invention, the fixture includes a carrier plate and a cover plate. Before implanting the circuit board, the handling device removes the cover plate from the carrier plate and transports it to the cover plate temporary storage platform, and the cover plate temporary storage platform and the circuit board supply device are arranged on both sides of the fixture conveying device; after implanting the circuit board on the carrier plate, the handling device places the cover plate back on the carrier plate and covers or partially covers the circuit board implanted on the carrier plate.

[0009] As can be seen from the above solution, by arranging the circuit board supply device and the cover plate temporary storage platform on both sides of the fixture conveying device, the transfer of the cover plate does not affect the supply of the circuit board and the implantation of the circuit board onto the carrier plate.

[0010] According to a specific embodiment of the present invention, the grasping mechanism is rotatably arranged on the Z-axis moving module and includes a vacuum generator and a suction cup. By rotatably arranging the grasping mechanism, the suction cup can grasp the circuit board or the cover plate more flexibly.

[0011] According to a specific embodiment of the present utility model, the board planting machine further includes a suction cup quick replacement device, which replaces the suction cup on the suction cup replacement platform, and the suction cup replacement platform and the cover plate temporary storage platform are located on the same side of the fixture conveying device. The suction cup can be quickly replaced by the suction cup quick replacement device, and at the idle position in the board planting machine that the suction cup can reach, it is convenient to replace and does not affect the operation of other devices.

[0012] According to a specific embodiment of the present utility model, the fixture conveying device includes a jacking mechanism for jacking up the fixture placed on the fixture conveying device from below. Through the jacking of the jacking mechanism, the circuit board is implanted into the fixture.

[0013] According to a specific embodiment of the present utility model, a positioning camera is provided above the circuit board placement position of the board planting machine. The specific position of the circuit board at the circuit board placement position is determined by the positioning camera.

[0014] According to a specific embodiment of the present utility model, a first detection camera is provided on the Z-axis moving module.

[0027] In the following description, many specific details are set forth in order to fully understand the present utility model. However, it is easily understood by those skilled in the art that the present utility model can also be implemented in other ways different from those described herein. Therefore, other implementable ways that can be known by those skilled in the art based on the embodiments described in this application all fall within the protection scope of this application.

[0028] The words indicating directions such as "front", "rear", "left", and "right" mentioned in this embodiment are for the sake of clear expression and do not determine the position and direction. In other specific embodiments, the positional relationships of various devices and mechanisms may be different.

[0029] As Figure 1 and Figure 2 shown, the board implanting machine 100 includes a machine shell 10 and a frame 11. A working surface is provided on the frame 11, and a handling device 20, a fixture conveying device 30, and a turning device 40 can be arranged on the working surface. Among them, the circuit board supply device 50 is arranged on the front side of the fixture conveying device 20.

[0030] As Figure 3 and Figure 4As shown in the figure, the handling device 20 includes a Y-axis movement module 21, an X-axis movement module 22, and a Z-axis movement module 23. The grasping mechanism is arranged below the Z-axis movement module. The first movement track 111 that guides the movement of the Y-axis movement module 21 is arranged at the top of the frames 11 on both sides. The two ends of the second movement track 211 that guides the movement of the X-axis movement module 22 are respectively arranged on the first movement track 111. Among them, the Y-axis movement module 21 can drive the X-axis movement module 22 and the second movement track 211 to reciprocate along the Y-axis direction along the first movement track 111. The X-axis movement module 22 can drive the Z-axis movement module 23 to reciprocate along the X-axis direction under the guidance of the second movement track 211, and the Z-axis movement module 23 can drive the grasping mechanism to reciprocate along the Z-axis direction, that is, the vertical direction. Among them, the X-axis is the left-right direction, the Y-axis is the front-back direction, and both the X-axis movement module 22 and the Z-axis movement module 23 can be driven by a lead screw to move.

[0031] Among them, the grasping mechanism is rotatably arranged on the Z-axis movement module 23 and includes a vacuum generator and a suction cup. A first detection camera may also be arranged on the Z-axis movement module 23. The suction cup can be quickly replaced through a suction cup quick change device. Among them, the suction cup can adopt an automatic quick change module to realize the automatic switching of the air circuit and the circuit. The suction cup quick change device may include a manipulator with three-dimensional movement.

[0032] From the above, it can be seen that the suction cup of the grasping mechanism can basically move within the space range of the entire plate planting machine to grasp products located at any position within the plate planting machine.

[0033] The fixture conveying device 30 includes a conveying component 31 and a translation component 32. Among them, the conveying component 31 conveys from left to right and can be connected to the feeding device on the left side outside the machine shell 10. The carrier plate with a cover can enter the conveying component 31 through the feeding device, and the products that have completed implantation can be output from the conveying component 31 to the outside of the plate planting machine and collected by the receiving device. The translation component 32 can move along the conveying direction and the reverse direction of the conveying direction between the first position and the second position. A negative pressure cleaning component may be arranged above the fixture conveying device 30 to clean the carrier plate, and a second detection camera may be arranged below to perform detection and positioning. The conveying component 31 may also include a track adjusting mechanism for adjusting the track width, and a positioning mechanism for positioning or fixing the carrier plate or the translation component, etc.

[0034] The circuit board supply device 50 may have a circuit board placement position and a collection position. Wherein, trays or separator papers with circuit boards can be stacked in the circuit board storage space 53. After the circuit boards in the trays or on the separator papers located at the circuit board placement position are implanted into the carrier boards, the empty trays or separator papers can be transported to the collection position by the pushing mechanism 52 for collection, and then stacked in the collection space 54. The circuit boards in the circuit board storage space 53 are pushed upward by the stepper screw motor 51, so that the trays or separator papers are lifted to the circuit board placement position. A positioning camera may also be provided above the circuit board placement position to determine the position of the circuit board and transmit relevant information to the handling device 20.

[0035] Figure 5 And Figure 6 shows the positional relationship between the fixture conveying device 30 and the turning device 40. As Figure 5 and Figure 6 shown, the turning device 40 includes a rotatable receiving plate 41, a support mechanism 42, a rotation driving mechanism, and a moving driving mechanism 43 for moving the receiving plate 41 and the support mechanism 42 in the vertical direction. The support mechanism 42 is arranged across the fixture conveying device 30, so as to support the receiving plate 41 above the conveying assembly 31. When the receiving plate 41 is horizontally arranged, at least part of the projection in the vertical direction covers the second position of the translation assembly 32. When the receiving surface of the receiving plate 41 faces upward, after the handling device 20 places the circuit board on the receiving surface and moves out of the circuit board turning position, the circuit board is adsorbed on the receiving surface. Then the moving driving mechanism 43 drives the support mechanism 42 to drive the receiving plate 41 to move upward. After there is enough space for the receiving plate 41 to turn over, the rotation driving mechanism drives the receiving plate 41 to rotate 180°. At this time, the receiving surface faces downward. The moving driving mechanism 43 drives the receiving plate 41 to move downward. The translation assembly 32 with the carrier board and the cover plate on the carrier board removed moves to the second position. The lifting mechanism drives the carrier board to rise until the circuit board is implanted into the carrier board. The lifting mechanism descends, so that the translation assembly moves the carrier board with the implanted circuit board from the second position to the first position.

[0036] Figure 7 shows the relationship between the positions on the working surface, and it can be seen that the position layout of this embodiment is compact and the space utilization rate is high. Figure 8 And Figure 9 shows the working processes of two implantation methods.

[0037] The following refers to Figures 7 to 9Describe the circuit board implantation process. First, describe the implantation of a circuit board without turning it over. The carrier board with a cover plate enters the carrier board placement position via the conveying component 31 and is positioned or fixed. The carrier board placement position can coincide or partially coincide with the first position of the translation component 32. The handling device 20 is activated, grabs the cover plate and places it on the cover plate temporary storage platform. Then, the handling device 20 moves above the circuit board placement position, grabs the circuit board and moves it above the carrier board, and is positioned by the first detection camera. The lifting mechanism lifts the carrier board until the circuit board is implanted into the carrier board. The handling device 20 releases the circuit board, and the lifting mechanism drives the carrier board with the implanted circuit board to return to its original position. Then, the handling device 20 grabs the cover plate from the cover plate temporary storage platform and moves it above the carrier board, and can be positioned by the first detection camera. The lifting mechanism lifts the carrier board until the cover plate is implanted into the circuit board and / or the carrier board. The handling device 20 releases the cover plate, and the lifting mechanism returns to its original position. The implantation of the circuit board between the carrier board and the cover plate is completed. The carrier board with the circuit board and the cover plate is conveyed by the conveying component 31 to the receiving device outside the board implanting machine for collection. The feeding device places another carrier board with a cover plate on the fixture conveying device 30 and moves it to the carrier board placement position to perform the next circuit board implantation.

[0038] Next, describe the implantation of a circuit board that needs to be turned over. The carrier board with a cover plate enters the carrier board placement position via the fixture conveying device 30 and is positioned or fixed. At this time, the translation component 32 is in the first position and supports the carrier board. The handling device 20 is activated, grabs the cover plate and places it on the cover plate temporary storage platform. Then, the handling device 20 moves to the circuit board placement position, grabs the circuit board, and places it on the receiving plate 41 of the turning device 40. The handling device 20 moves away. The receiving plate 41 is driven by the moving drive mechanism to rise. After there is enough space, the rotation drive mechanism drives the receiving plate 41 to rotate 180 degrees to turn the circuit board over. The translation component 32 moves the carrier board with the removed cover plate to the second position and is located below the receiving plate. The moving drive mechanism 43 drives the receiving plate 41 to descend. The lifting mechanism lifts the carrier board until the circuit board is implanted into the carrier board. The lifting mechanism drives the carrier board with the implanted circuit board to descend. Then, the translation component 32 moves the carrier board to the first position. The handling device 20 grabs the cover plate from the cover plate temporary storage platform and moves it above the carrier board, and is positioned by the first detection camera. The lifting mechanism lifts the carrier board until the cover plate is implanted into the circuit board and / or the carrier board. The handling device 20 releases the cover plate, and the lifting mechanism returns to its original position. The implantation of the circuit board between the carrier board and the cover plate is completed. The carrier board with the circuit board and the cover plate is conveyed by the conveying component 31 to the receiving device outside the board implanting machine for collection. The feeding device places another carrier board with a cover plate on the fixture conveying device 31 and moves it to the carrier board placement position to perform the next circuit board implantation.

[0039] Although the present utility model is disclosed above with the preferred embodiments, it is not intended to limit the scope of implementation of the present utility model. Any ordinary technician in the art can make some improvements without departing from the scope of the invention of the present utility model. That is, any changes or improvements made in accordance with the present utility model shall be covered by the protection scope of the present utility model.
