Referring to fig. 1 to 9, the embodiment of the present application discloses a carrying device for carrying a product 700, and also can lock or unlock the product 700. The product 700 may be a PCB board, and of course, may also be other components, and the type of the product 700 in the embodiment of the present application is not specifically limited. The disclosed carrier includes a carrier 100, a drive mechanism 200, and a plurality of latches 300.

The carrier 100 is a base member of a carrier device that provides a load bearing basis for the product 700 and a mounting basis for the latch 300. In some embodiments, the carrier 100 is provided with a receiving groove 110, the receiving of the product 700 can be achieved through the receiving groove 110, and the lateral (possibly horizontal) movement of the product 700 can be restricted by the side wall of the receiving groove 110, so that the positional accuracy of the product 700 can be ensured to some extent.

The plurality of latches 300 are distributed around the accommodating groove 110, and when the product 700 is placed in the accommodating groove 110, the edges of the product 700 can be limited by the plurality of latches 300, so that the longitudinal (vertical) movement of the product 700 can be limited, and further, the product 700 can be prevented from moving in the accommodating groove 110 to affect the position accuracy or separating from the accommodating groove 110.

In some embodiments, each latch 300 includes a base 310, a connecting shaft 320, and a pressing block 330, wherein the base 310 is connected to the carrier 100, the connecting shaft 320 is movably and rotatably disposed on the base 310, and the pressing block 330 is connected to one end of the connecting shaft 320. Based on this, the pressing block 330 may move and rotate with the connection shaft 320 with respect to the base 310, so that the distance between the pressing block 330 with respect to the surface of the product 700 may be adjusted to enable the pressing block 330 to press against the surface of the product 700 or to be separated from the surface of the product 700, and at the same time, the pressing block 330 may also rotate with the connection shaft 320 with respect to the base 310, so that the pressing block 330 may be rotated into or out of the notch of the receiving groove 110.

Further, in order to enable both the pressing block 330 and the connection shaft 320 to move and rotate with respect to the base 310, in the embodiment of the present application, one of the connection shaft 320 and the base 310 is provided with a chute, and the other is provided with a push rod 340 engaged with the chute, specifically, one end of the push rod 340 is inserted into the chute. Based on this, when the connecting shaft 320 moves along the self axis relative to the base 310, the side walls of the chute and the side walls of the push rod 340 are pressed against each other, and under the action of the pressing force, the connecting shaft 320 can rotate around the self axis, that is, the connecting shaft 320 moves along the self axis and rotates around the self axis, so that the pressing block 330 can be synchronously driven to move and rotate, so that the pressing block 330 rotates to be separated from the surface of the product 700 or rotationally presses the surface of the product 700, and the product 700 is prevented from being scratched due to contact with the surface of the product 700 in the process of rotating the pressing block 330.

To apply a driving force to the connection shaft 320 to move and rotate, in the embodiment of the present application, the driving mechanism 200 has an abutting portion for contacting with the connection shafts 320 of the plurality of latches 300, respectively, so as to apply a driving force to the connection shafts 320 of the plurality of latches 300.

Illustratively, a plurality of propping portions may be provided, and the plurality of propping portions are provided in one-to-one correspondence with the connecting shafts 320 of the plurality of latches 300, so as to respectively prop against the connecting shafts 320 provided correspondingly by the plurality of propping portions; of course, the propping portion may be an integral body, which can simultaneously prop against the connecting shafts 320 of the plurality of latches 300. Based on this, under the driving action of the driving mechanism 200, the propping portion props against the connecting shaft 320, the pressing block 330 is driven by the connecting shaft 320 to gradually get away from the surface of the product 700, and the pressing block 330 rotates around the axis thereof along with the connecting shaft 320, so that the pressing block 330 rotates to be separated from the surface of the product 700, and the pressing block 330 is prevented from scratching the surface of the product 700.

Based on the above arrangement, in the first state, the pressing block 330 is located in the notch of the accommodating groove 110, in this state, the propping portion of the driving mechanism 200 is spaced from each connecting shaft 320 without propping the connecting shaft 320, the pressing block 330 is in a limiting state, and at this time, the pressing block 330 presses the surface of the product 700, so that under the pressing action of the pressing block 330, the product 700 can be effectively prevented from moving or separating from the accommodating groove 110.

In the second state, the propping portion of the driving mechanism 200 is propped against the connecting shaft 320, and drives the pressing block 330 to be far away from the accommodating groove 110 through the connecting shaft 320, so that the surface of the pressing block 330 is separated from the surface of the product 700, and meanwhile, the connecting shaft 320 is rotated while moving, so that the pressing block 330 is rotated out of the notch, and the limiting effect on the product 700 is relieved.

It should be noted here that the power of the surface of the pressing block 330 away from the product 700 comes from the driving mechanism 200, and the power of the surface of the pressing block 330 close to the product 700 may come from different members. In some embodiments, the propping portion of the driving mechanism 200 may be connected to the connecting shaft 320 and may rotate relatively, in which case, the driving mechanism 200 may drive the pressing block 330 via the connecting shaft 320 to approach the surface of the product 700, and rotate the pressing block 330 along with the connecting shaft 320 under the interaction of the chute and the ejector 340, so as to compress the product 700.

In other embodiments, the force of the pressing block 330 approaching the surface of the product 700 may also be from the gravity action of both the connecting shaft 320 and the pressing block 330, at which time the abutting portion of the driving mechanism 200 may be separated from the end of the connecting shaft 320, in which case the pressing block 330 is made to approach the surface of the product 700 by the gravity action of both the pressing block 330 and the connecting shaft 320, and the connecting shaft 320 and the pressing block 330 are made to rotate by the interaction of the chute and the ejector rod 340, so as to compress the product 700.

In still other embodiments, in order to further enhance the compacting effect of the pressing block 330 on the product 700, a return structure (i.e., an elastic element 350 described below) may be additionally provided, which may be overlapped with the gravity of both the connection shaft 320 and the pressing block 330, the pressing block 330 approaches the surface of the product 700 under the overlapped force, and the connection shaft 320 and the pressing block 330 are rotated under the interaction of the chute and the push rod 340, thereby achieving the compacting of the product 700.

In addition to the above manner, the pressing block 330 may be moved close to the surface of the product 700 in other manners, so as to achieve the pressing effect of the pressing block 330 on the product 700, which is not specifically limited in the embodiment of the present application.

In addition, the fact that the press block 330 is located within the notch of the receiving groove 110 means that the projection of the press block 330 in the plane parallel to the groove bottom of the receiving groove 110 is located inside the receiving groove 110, and the fact that the press block 330 is located outside the notch of the receiving groove 110 means that the projection of the press block 330 in the plane parallel to the groove bottom of the receiving groove 110 is located outside the receiving groove 110.

In this embodiment, the product 700 can be carried and accommodated in the accommodating groove 110 of the carrying member 100, the product 700 can be limited in the accommodating groove 110 by the plurality of latches 300, or the limitation of the product 700 is released, specifically, when the product 700 needs to be limited, the propping portion of the driving mechanism 200 is separated from the connecting shaft 320, at this time, the pressing block 330 is located in the notch of the accommodating groove 110 and presses the surface of the product 700 placed in the accommodating groove 110, so as to limit the product 700, and ensure that the product 700 cannot move in the accommodating groove 110 or separate from the accommodating groove 110; when the product 700 needs to be taken out, the locking effect of the plurality of locks 300 needs to be released, in this case, the propping part of the driving mechanism 200 contacts with the connecting shafts 320 of the plurality of locks 300 and props against each connecting shaft 320, so that the pressing block 330 is gradually far away from the surface of the product 700 under the driving of the connecting shaft 320, and meanwhile, due to the cooperation of the chute and the ejector rod 340, the connecting shaft 320 is rotated while moving, so that the pressing block 330 is gradually rotated out of the notch while being far away from the surface of the product 700, and the limiting effect of the pressing block 330 on the product 700 is released, so that the product 700 is taken out from the accommodating groove 110. Compared with the rotary tripping mode in the related art, the pressing block 330 in the embodiment of the application cannot be in contact with the surface of the product 700 in the rotary process, so that friction action does not exist between the pressing block 330 and the product 700, and the situation that the surface of the product 700 is damaged due to the rotation of the pressing block 330 in the tripping process can be effectively avoided, and the quality of the product 700 is further guaranteed.

Referring to fig. 7 to 9, in some embodiments, the side wall of the connecting shaft 320 is provided with a cam groove 321 which is inclined as a chute, the cam groove 321 is formed along the peripheral surface of the connecting shaft 320 and forms a preset included angle with the axis of the connecting shaft 320, and the connecting shaft 320 can rotate around the axis of the connecting shaft by ensuring the design of the preset included angle when moving along the axis of the connecting shaft, so as to avoid the self-locking phenomenon to affect the movement and rotation of the connecting shaft 320. It should be noted that, the angle range of the preset included angle may be designed according to parameters such as a friction coefficient between the cam slot 321 and the ejector rod 340, so long as the connecting shaft 320 can rotate without self-locking under the condition of being pushed, and the specific design principle may refer to the related art, and will not be described in detail herein.

The side wall of the base 310 is provided with a mounting hole 311, the ejector rod 340 is arranged in the mounting hole 311 in a penetrating way, and the end part of the ejector rod 340 is positioned in the cam groove 321. Illustratively, the base 310 may be provided with a sliding channel through which the connection shaft 320 is penetrated, and the connection shaft 320 may move along the sliding channel and rotate. The mounting hole 311 penetrates through the side wall of the sliding channel, so that the ejector rod 340 can extend into the sliding channel through the mounting hole 311 and finally extend into the cam groove 321 of the connecting shaft 320, when the connecting shaft 320 is pushed, the connecting shaft 320 can rotate under the cooperation of the ejector rod 340 and the cam groove 321, and then the pressing block 330 can be driven to synchronously move and rotate, so that the pressing block 330 is enabled to rotate close to or rotate away from the surface of the product 700, and surface scratches of the product 700 are avoided.

Further, as shown in fig. 9, the cam groove 321 is provided with a first groove end 3211 and a second groove end 3212 along its length direction, when the connecting shaft 320 moves and rotates, the ejector rod 340 is located between the first groove end 3211 and the second groove end 3212, so that when the first groove end 3211 contacts with the ejector rod 340 or the second groove end 3212 contacts with the ejector rod 340, the connecting shaft 320 is limited to not move and rotate any more, so that the pressing block 330 rotates within a certain angle range and moves within a certain distance, thereby not only ensuring that the pressing block 330 can press the product 700, but also not transitioning.

In some embodiments, the press block 330 may be rotated 90 ° with the connection shaft 320 from a state where the first slot end 3211 is in contact with the push rod 340 to a state where the second slot end 3212 is in contact with the push rod 340. Specifically, in a state that the first groove end 3211 is in contact with the ejector pin 340, the pressing block 330 is located within the notch of the accommodating groove 110 and abuts against the surface of the product 700, so that the product 700 can be limited, and the product 700 is prevented from moving in the accommodating groove 110 or being separated from the accommodating groove 110 at will; in a state where the second groove end 3212 is in contact with the push rod 340, the pressing block 330 is rotated out of the notch of the receiving groove 110 and is separated from the surface of the product 700, so that the product 700 can be contact-limited to facilitate the removal of the product 700 from the receiving groove 110.

In other embodiments, from the state that the first slot end 3211 contacts the mandrel 340 to the state that the second slot end 3212 contacts the mandrel 340, the pressing block 330 may further rotate by other angles along with the connecting shaft 320, and in particular, may be greater than 90 ° and less than 270 °, so as to ensure that the pressing block 330 rotates out of the slot.

To enhance the compression of the product 700 by the press 330, the latch 300 may further include an elastic member 350, as shown in fig. 8, where the elastic member 350 connects the connection shaft 320 and the carrier 100, and is configured to drive the press 330 to approach the carrier 100 via the connection shaft 320. For example, the elastic element 350 may be a spring, one end of which abuts against the connecting shaft 320, and the other end abuts against the bottom surface of the carrier 100, and under the action of the elastic force of the spring, the connecting shaft 320 has a downward movement trend at all times, and under the action of the connecting shaft 320, the pressing block 330 has a pressing trend at all times to press the surface of the product 700. Specifically, when the propping end of the driving mechanism 200 is separated from the connecting shaft 320, the spring can drive the connecting shaft 320 and the pressing block 330 to move, and the connecting shaft 320 rotates synchronously, so that the pressing block 330 presses the surface of the product 700.

Further, an end surface of the connecting shaft 320 abutting against the spring may be provided with a mounting groove, the spring is sleeved on the outer side of the connecting shaft 320, and one end of the spring is located in the mounting groove, so that the spring can be effectively prevented from being inclined.

In addition, a groove may be provided at a portion of the carrier 100 abutting against the spring, and the other end of the spring may be positioned in the groove, so that the other end of the spring may be prevented from sliding with respect to the carrier 100.

Referring to fig. 6, in order to prevent the carrier 100 from interfering with the movement of the connection shaft 320, in this embodiment, a plurality of avoidance holes 120 are provided in the area of the carrier 100 around the accommodating groove 110, and the connection shaft 320 of each of the plurality of latches 300 passes through the plurality of avoidance holes 120 in a one-to-one correspondence manner, so that the connection shaft 320 can move in the avoidance hole 120, so as to avoid the carrier 100 interfering with the movement of the connection shaft 320.

The press block 330 is located on a first side of the carrier 100, and the base 310 is connected to a second side of the carrier 100. Illustratively, the carrier 100 may be a carrier plate, the base 310 is fixed to the bottom surface of the carrier plate by fasteners, and the pressing block 330 is mounted to the top end of the connection shaft 320 after the top end of the connection shaft 320 passes through the escape hole 120. The pressing block 330 may be mounted to the connecting shaft 320 in a threaded manner, and of course, the pressing block 330 may be locked to the connecting shaft 320 by a locking member (such as a locking nut, etc.), so as to ensure the installation firmness between the pressing block 330 and the connecting shaft 320.

Specifically, two ends of the carrier 100 along the third direction are respectively overlapped on the first conveying belt 410 and the second conveying belt 420, the carrier 100 can be driven to move along the second direction by the first conveying belt 410 and the second conveying belt 420, so as to realize the transmission of the product 700 borne by the carrier 100, and two ends of the carrier 100 along the third direction can be respectively limited by the first limiting plate 430 and the second limiting plate 440, so that the carrier 100 can be prevented from being separated from the conveying mechanism 400, and the stable transmission of the carrier 100 and the product 700 borne by the carrier 100 is ensured.

It should be noted that, the height dimension of the first spacing space along the first direction is slightly greater than the thickness dimension of one end of the carrier 100, and the height dimension of the second spacing space along the first direction is slightly greater than the thickness dimension of the other end of the carrier 100, so that the two ends of the carrier 100 can be prevented from rubbing against the first spacing plate 430 and the second spacing plate 440 to affect smooth transmission of the carrier 100 and the product 700 carried thereby. In addition, the first direction, the second direction, and the third direction are perpendicular to each other, and for example, the first direction may be an up-down direction, the second direction may be a left-right direction, and the third direction may be a front-back direction (or a direction perpendicular to the screen inward or outward).

Referring to fig. 1 and 2, in order to ensure the positional accuracy of the carrier 100 and the product 700 carried thereby, the carrier device may further include a limiting mechanism 500, and the limiting mechanism 500 may block the carrier 100 to ensure that the carrier 100 stops after moving to a predetermined position, thereby ensuring the positional accuracy of the carrier 100.

In some embodiments, the limiting mechanism 500 may be disposed at a front position of the carrier 100 and the product 700 carried by the carrier, that is, during the movement of the carrier 100 along the conveying direction (i.e., the second direction) carried by the conveying mechanism 400, the limiting mechanism 500 may block the carrier 100, so as to ensure that the carrier 100 stops moving after being conveyed to the preset position.

The limiting mechanism 500 may include a second driving module 510 and a stop block 520, where the driving end of the second driving module 510 is movable along a first direction, the stop block 520 is connected with the driving end of the second driving module 510, and the second driving module 510 is configured to drive the stop block 520 to extend or retract along the first direction, so as to block the carrier 100 or release the carrier 100 through the stop block 520. The second driving module 510 may be a cylinder, but may be other components, and the specific type is not limited.

When the carrier 100 is moved by the conveying mechanism 400, the second driving module 510 can drive the stop block 520 to rise, so that the stop block 520 moves onto the conveying path of the carrier 100, and when the carrier 100 moves to contact with the stop block 520, the carrier 100 is blocked by the stop block 520 and cannot continue to move, and at this time, the carrier 100 and the product 700 carried by the carrier are indicated to move to a preset position; then the next procedure can be carried out; after the process is completed, the second driving module 510 drives the stop block 520 to descend, so that the stop block 520 is separated from the transmission path of the carrier 100, thereby removing the blocking effect on the carrier 100, so that the transmission mechanism 400 can continuously carry the carrier 100 to move to realize the transmission of the product 700.

Referring to fig. 1, in some embodiments, the carrier may further include a frame 600 that may provide a support and mounting basis for the components of the drive mechanism 200, the transport mechanism 400, the spacing mechanism 500, and the like. Specifically, the first driving module 210 of the driving mechanism 200 may be mounted to the rack 600 to ensure stability of the driving mechanism 200; the body of the transfer mechanism 400 may be mounted to the frame 600 to ensure stability of the transfer mechanism 400; the second driving module 510 of the spacing mechanism 500 may be mounted to the frame 600 to ensure the stability of the spacing mechanism 500.

And (3) a falling lock process:

in the initial state, the plurality of convex columns 220 of the driving mechanism 200 jack up the connecting shafts 320 of the plurality of latches 300 respectively, so that the pressing blocks 330 of the plurality of latches 300 are positioned at positions far away from the accommodating groove 110 and outside the notch respectively; placing the product 700 into the receiving groove 110 of the carrier 100; the moving plate 240 drives the plurality of convex columns 220 to move downwards, the connecting shaft 320 moves downwards under the combined action of the gravity of the pressing block 330 and the connecting shaft 320 and the elasticity of the elastic element 350, and the connecting shaft 320 rotates while moving downwards under the action of the chute and the ejector rod 340, the pressing block 330 is driven to rotate to be close to the product 700 through the connecting shaft 320, and finally the product 700 is pressed through the pressing block 330, so that falling locking is realized.

In summary, the carrying device in the embodiment of the present application does not contact with the surface of the product 700 when the limiting effect of the lock catch 300 is released, so that the product 700 is not damaged, and the carrying device has relatively fewer parts, relatively simple structure, strong universality and wide application range; in addition, the arrangement of the lock catch 300 and the driving mechanism 200 fully utilizes the platform space of the bearing device, does not occupy the resources and time of the mechanical arm, and can improve the working efficiency of the product 700 to a certain extent.
