[0023] The utility model provides the following description with reference to the accompanying drawings to help fully understand the various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

[0024] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0025] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0026] The embodiment of the utility model provides a multifunctional circuit board grabbing device, such as Figure 1-3As shown, the rack 100 includes a first support rod 210, a second support rod 220 and two third support rods 230 at the bottom of the rack 100. The first support rod 210 and the second support rod 220 both extend along the length direction of the circuit board and are spaced apart by a preset distance (the preset distance is determined by those skilled in the art according to actual conditions), the two third support rods 230 both extend along the width direction of the circuit board and are also spaced apart by a certain distance (the certain distance is also determined by those skilled in the art according to actual conditions), and the two third support rods 230 are respectively arranged at both ends of the first support rod 210 and the second support rod 220, that is, the two third support rods 230 are respectively arranged at both ends of the first support rod 210 and at both ends of the second support rod 220. Thus, the first support rod 210, the second support rod 220 and the two third support rods 230 can form a frame-like structure, which is compatible with the rectangular structure of the circuit board, thereby providing conditions for grabbing the four edge positions of the circuit board.

[0027] A plurality of first gripping assemblies 300 for gripping circuit boards are fixed on the first support bar 210, the second support bar 220 and the two third support bars 230, and second gripping assemblies 400 for gripping trays are disposed at both ends of the first support bar 210 and the second support bar 220. Therefore, the multifunctional circuit board gripping device of this embodiment can not only grip circuit boards individually, but also grip trays for loading circuit boards, and has more diverse functions.

[0028] In some embodiments, the second grasping assembly 400 includes a clamp block 410, a clamp plate 420 and a clamp plate driving mechanism 430. The clamp plate driving mechanism 430 is connected to the clamp plate 420. The clamp plate driving mechanism 430 can drive the clamp plate 420 to move to the bottom of the clamp block 410 and upward toward the clamp block 410 for clamping the tray. The clamp plate driving mechanism 430 can also drive the clamp plate 420 downward away from the clamp block 410 and move out from under the clamp block 410 for releasing the tray.

[0029] In this embodiment, the clamping plate driving mechanism 430 can drive the clamping plate 420 to approach the clamping block 410 in the vertical direction so as to clamp the pallet through the clamping block 410 and the clamping plate 420, or can drive the clamping plate 420 to move away from the clamping block 410 in the vertical direction so as to release the pallet. At the same time, the clamping plate driving mechanism 430 drives the clamping plate 420 to move below the clamping block 410, and can also drive the clamping plate 420 to move below the pallet, and the clamping block 410 and the clamping plate 420 are respectively located above and below the pallet to provide conditions for clamping the pallet, or the clamping plate driving mechanism 430 drives the clamping plate 420 to move out from below the clamping block 410, and can also drive the clamping plate 420 to move out from below the pallet, and under the action of gravity, the pallet can fall downward, so that the pallet is separated from the second grabbing assembly 400.

[0030] Furthermore, the clamp driving mechanism 430 includes a rotary pressing cylinder, a push rod of which is connected to the clamp 420. The rotary pressing cylinder can drive the clamp 420 to move in the vertical direction to get closer to or away from the clamp block 410. The rotary pressing cylinder can also drive the clamp 420 to rotate around the axis of the push rod so that the clamp 420 rotates to the bottom of the pallet or moves away from the bottom of the pallet.

[0031] In some embodiments, the first gripping component 300 includes a suction nozzle 310 for adsorbing the circuit board. The suction nozzle 310 is connected to a corresponding vacuum device, which can generate negative pressure at the suction nozzle 310. The circuit board can be adsorbed by utilizing this adsorption force.

[0032] In some embodiments, the first support rod 210 and the second support rod 220 are both slidably connected to the rack 100 along the width direction of the circuit board, and the two third support rods 230 are both slidably connected to the rack 100 along the length direction of the circuit board. The frame 100 is also provided with a first drive assembly 610, a second drive assembly 620 and two third drive assemblies 630. The first drive assembly 610 is connected to the first support rod 210 and is used to drive the first support rod 210 to slide along the width direction of the circuit board. The second drive assembly 620 is connected to the second support rod 220 and is used to drive the second support rod 220 to slide along the width direction of the circuit board. When one of the first support rod 210 and the second support rod 220 slides along the width direction of the circuit board or the first support rod 210 and the second support rod 220 slide in opposite directions, the spacing between the first support rod 210 and the second support rod 220 can be changed to adapt to circuit boards of different widths; and when the first support rod 210 and the second support rod 220 move synchronously in the same direction, the initial positions of the first support rod 210 and the second support rod 220 can be changed to adapt to the position of the circuit board.

[0033] The two third driving assemblies 630 are respectively connected to the two third support rods 230, and are respectively used to drive the two third support rods 230 to slide along the length direction of the circuit board. When one of the two third support rods 230 slides along the length direction of the circuit board or the two third support rods 230 slide in opposite directions, the distance between the two third support rods 230 can be changed to adapt to circuit boards of different lengths; and when the two third support rods 230 move synchronously in the same direction, the initial positions of the two third support rods 230 can be changed to adapt to the position of the circuit board.

[0034] Therefore, the multifunctional circuit board grabbing device of this embodiment is more flexible and can grab circuit boards of different sizes and can also adapt to circuit boards in different positions.

[0035] In some embodiments, the bottom of the rack 100 is fixed with a first guide rod 110 and a second guide rod 120 extending along the width direction of the circuit board and two groups of third guide rods 130 extending along the length direction of the circuit board. The first guide rod 110 and the second guide rod 120 pass through the first support rod 210 and the second support rod 220 respectively. The first support rod 210 and the second support rod 220 are naturally provided with through holes for the corresponding guide rods to pass through. The first support rod 210 can slide along the first guide rod 110, and the second support rod 220 can slide along the second guide rod 120, so as to realize that the first support rod 210 and the second support rod 220 are both slidably connected to the rack 100 along the width direction of the circuit board.

[0036] The two groups of third guide rods 130 pass through the two third support rods 230 respectively. The third support rods 230 are naturally provided with through holes for the third guide rods 130 to pass through. The two third support rods 230 can slide along the two groups of third guide rods 130 respectively to achieve that the two third support rods 230 are slidably connected to the rack 100 along the length direction of the circuit board.

[0037] In some embodiments, a first sensor 510 and a second sensor 520 are fixed on the frame 100, the first sensor 510 is located above the first support rod 210, and the second sensor 520 is located above one of the third support rods 230, and both the first sensor 510 and the second sensor 520 are used to detect the distance from the pallet.

[0038] The first sensor 510, the second sensor 520, the first grabbing assembly 300, the second grabbing assembly 400, the first drive assembly 610, the second drive assembly 620 and the third drive assembly 630 can all be connected to the controller. The controller can determine whether the distance is less than a preset distance based on the distance detected by the first sensor 510 and the second sensor 520. If it is less than the preset distance, it means that the distance from the tray to the first grabbing assembly 300 is closer. The first drive assembly 610, the second drive assembly 620 and the third drive assembly 630 can be operated so that the first grabbing assembly 300 on the first support rod 210, the second support rod 220 and the third support rod 230 will not touch the tray, thereby playing a role of avoiding position.

[0039] The first sensor 510 and the second sensor 520 may both be distance sensors, specifically laser distance sensors.

[0040] The terms and words used in the above description and claims are not limited to the literal meanings, but are only used by the applicant to enable a clear and consistent understanding of the utility model. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the utility model is provided only for illustration, and not for limiting the utility model as defined by the attached claims and their equivalents.
