The product comprises the display module or the component elements of the display module, such as a screen body and a circuit board. In the embodiment of the present invention, the conveying mechanism is described by taking the display module as an example of the conveying object, but it should be understood that the conveying tool of the embodiment of the present invention may be used for conveying as long as the conveying tool can be matched with the conveying mechanism of the embodiment of the present invention.

As shown in fig. 1, fig. 1 illustrates an overall structure of a carrying mechanism 10 according to an embodiment of the present invention. As shown in fig. 2, fig. 2 is a side view of a carrying mechanism 10 according to an embodiment of the present invention.

The carrying mechanism 10 includes a base plate 110, and a clamping mechanism 20 and a vacuum suction mechanism 30 disposed on the base plate 110, wherein the base plate 110 is used for pressing the display module onto a carrier (not shown), the clamping mechanism 20 is used for clamping the carrier, and the vacuum suction mechanism 30 is used for sucking the display module.

The base plate 110 includes opposite top and

bottom surfaces

111 and 112, and the top surface 111 of the base plate 110 is provided with a coupling head 120 for coupling to an external transfer component, such as the robot 50, as shown in fig. 3 and 4. After the transfer component is connected with the connector 120, the transfer component can transfer the carrying mechanism 10 together with the display module and the carrier, so that automatic transfer is realized. The specific structure of the connection head 120 is not limited, and may be matched with the interface of the transfer component according to the type of the transfer component. Moreover, a quick-change structure can be arranged between the connector 120 and the interface of the transfer component.

The jaw mechanism 20 is mounted on the base plate 110, wherein the jaw mechanism 20 is secured to the top surface 111 of the base plate 110. The clamping jaw mechanism 20 comprises a driving assembly 210, and a first clamping jaw 220 and a second clamping jaw 230 which are driven by the driving assembly 210 to move towards or away from each other, wherein the first clamping jaw 220 and the second clamping jaw 230 are arranged along a direction parallel to the top surface 111, and the first clamping jaw 220 and the second clamping jaw 230 are respectively positioned at two sides of the bottom plate 110. As shown in fig. 1 and 2, the first jaw 220 and the second jaw 230 are disposed at left and right sides of the base plate 110. The opposing movement of the first jaw 220 and the second jaw 230 means: the first jaw 220 and the second jaw 230 move closer to each other, and the distance between the two is reduced to clamp the object to be clamped, i.e. the carrier, between the two. The back-to-back motion of the first jaw 220 and the second jaw 230 means: the first jaw 220 and the second jaw 230 are moved away from each other, and the distance between them is increased to release the object to be clamped therebetween.

Specifically, the driving assembly 210 includes a first driving member 211 and a second driving member 212, the first clamping jaw 220 is connected to the first driving member 211, and the second clamping jaw 230 is connected to the second driving member 212. In this way, when the first clamping jaw 220 and the second clamping jaw 230 are used for clamping a carrier, the first clamping jaw 220 and the second clamping jaw 230 are independently controlled, can move simultaneously, and the speed of the two can be the same or different. Alternatively, one of the first jaw 220 and the second jaw 230 may be stationary and only the other may be movable. The first driving member 211 and the second driving member 212 are driven independently, and the movement of the first clamping jaw 220 and the second clamping jaw 230 can be flexibly controlled according to requirements, so that the application condition of the carrying mechanism 10 is expanded. The first driving member 211 and the second driving member 212 are both specifically air cylinders, but it should be noted that the types of the first driving member 211 and the second driving member 212 are not limited.

The first driving member 211 and the second driving member 212 are installed conveniently. As shown in fig. 1, in some embodiments, the top surface 111 of the base plate 110 is provided with a reinforcing rib 113, and the first driving member 211 and the second driving member 212 are supported and fixed to the reinforcing rib 113.

In other embodiments, the drive assembly 210 may be provided with only one drive that simultaneously controls movement of the first jaw 220 and the second jaw 230, the first jaw 220 and the second jaw 230 moving synchronously to move toward or away from each other. At this time, the first jaw 220 and the second jaw 230 may be simultaneously controlled using the motor shaft having both ends as output ends.

Referring to fig. 1 and 2 in combination, the vacuum suction mechanism 30 includes a suction cup 310, and a suction surface 311 is exposed from the bottom surface 112 of the base plate 110. That is, the bottom surface 112 of the bottom plate 110 is provided with a channel for the suction cup 310 to pass through, specifically, a kidney-shaped groove 114. When not sucking, the sucking surface 311 of the sucking disk 310 may be located above the top surface 111 of the base plate 110, or the sucking surface 311 of the sucking disk 310 may be located below the bottom surface 112 of the base plate 110. The upper side of the top surface 111 refers to the side of the top surface 111 opposite to the bottom surface 112, and the lower side of the bottom surface 112 refers to the side of the bottom surface 112 opposite to the top surface 111.

The operation of the conveying mechanism 10 is briefly described as follows: the connecting head 120 is connected to the robot 50, and then the carrying mechanism 10 is moved to the display module as a whole. Then, the display module is placed at the position of the carrier after being sucked by the suction cup 310 by means of the camera vision fixing system. The base plate 110 is moved downward and presses the display module, and the first clamping jaw 220 and the second clamping jaw 230 are controlled to move from two sides to each other and clamp the carrier. Then, the manipulator 50 is used to transfer the carrying mechanism 10, the display module and the carrier to the detection station, so that the carrier is butted with the positioning structure of the detection station. After the test of the previous detection station is completed, the manipulator 50 is used to transfer the carrying mechanism 10, the display module and the carrier to the next detection station. After all the tests are finished, the handling mechanism 10, the display module and the carrier are taken down from the last testing station by the manipulator 50 and transferred to the carrier storage area, then the first clamping jaw 220 and the second clamping jaw 230 are released, and the display module is transferred from the carrier to the display module storage area by the suction cup 310.

In the test process, the camera is only required to be used for positioning and shooting at the beginning to ensure the alignment precision of the display module and the carrier, and in the test process, the relative position of the display module and the carrier is not changed due to the integral transfer and carrying mechanism 10, so that the alignment precision of the display module and the carrier is not required to be ensured at each time, the operation is simple and convenient, and the efficiency is improved. In addition, the clamping jaw mechanism 20 and the vacuum adsorption mechanism 30 move together, when the clamping jaw mechanism 20 and the vacuum adsorption mechanism 30 need to be switched, the clamping jaw mechanism and the vacuum adsorption mechanism can be switched immediately and put into use, idle stroke movement of the switched elements is reduced, and conveying efficiency is improved.

The first jaw 220 and the second jaw 230 are used to clamp the carrier together from both sides. As shown in fig. 1 and 2, the first clamping jaw 220 is provided with a first positioning wheel 221, and the axial direction of the first positioning wheel 221 is perpendicular to the bottom surface 112; the second clamping jaw 230 is provided with a second positioning wheel 231, and the axial direction of the second positioning wheel 231 is perpendicular to the bottom surface 112. The first positioning wheel 221 and the second positioning wheel 231 each have an outer cylindrical surface. When the first clamping jaw 220 and the second clamping jaw 230 clamp the carrier, the first positioning wheel 221 is clamped into the circular arc-shaped groove on the left side of the carrier and forms surface contact with the inner wall of the groove, and the second positioning wheel 231 is clamped into the circular arc-shaped groove on the right side of the carrier and forms surface contact with the inner wall of the groove, so that a large contact area is provided, the positioning accuracy of the carrier is high, the first positioning wheel 221 and the second positioning wheel 231 cannot slide relative to the carrier along the edge of the carrier, and the clamping stability is guaranteed.

Specifically, as shown in fig. 2, the first clamping jaw 220 further includes a first transmission member 222 and a first connecting shaft 223, wherein the first transmission member 222 is connected to an output end of the first driving member 211, and two ends of the first connecting shaft 223 are respectively connected to the first transmission member 222 and the first positioning wheel 221. The first positioning wheel 221 may also be arranged in rotational connection with the first connecting shaft 223 so as to snap into a circular arc shaped recess on the right side of the vehicle. Similarly, the second clamping jaw 230 further comprises a second transmission piece 232 and a second connecting shaft 233, wherein the second transmission piece 232 is connected with the output end of the second driving piece 212, and two ends of the second connecting shaft 233 are respectively connected with the second transmission piece 232 and the second positioning wheel 231. The second positioning wheel 231 may be arranged in rotational connection with the second connecting shaft 233 so as to snap into the circular arc shaped recess on the right side of the carrier.

Further, the first positioning wheel 221 and the second positioning wheel 231 are arranged in pairs to form a positioning wheel set, that is, the first positioning wheel 221 and the second positioning wheel 231 are in one-to-one correspondence, and are opposite to each other in the left-right direction of the vehicle. By the means, after the first positioning wheel 221 and the second positioning wheel 231 are clamped into the arc-shaped grooves on the carrier, the directions of the clamping forces on the two sides are just opposite, the torque acting on the carrier is not generated by the clamping forces on the two sides, and the clamping stability can be improved.

As shown in fig. 1, two pairs of first positioning wheels 221 and two pairs of second positioning wheels 231 are provided to form two pairs of positioning wheel sets, so as to perform multi-point clamping on the carrier, thereby improving the stability of clamping. In a specific arrangement, the two first positioning wheels 221 are arranged in parallel, and the two first connecting shafts 223 are connected to the first transmission piece 222. The two second positioning wheels 231 are arranged in parallel, and the two second connecting shafts 233 are both connected to the second transmission member 232.

The first clamping jaw 220 and the second clamping jaw 230 are used for clamping the carrier from two sides together, so as to avoid misoperation and improve the accuracy of the first clamping jaw 220 and the second clamping jaw 230, as shown in fig. 1, in some embodiments, one of the first clamping jaw 220 and the second clamping jaw 230 is provided with a signal transmitting device 240, and the other of the first clamping jaw 220 and the second clamping jaw 230 is provided with a signal receiving device 250.

Specifically, the first clamping jaw 220 on the right side is provided with a signal transmitting device 240, the second clamping jaw 230 on the left side is provided with a signal receiving device 250, and both the signal transmitting device 240 and the signal receiving device 250 are located below the bottom surface 112. The signal transmitting device 240 is used for transmitting signals, and the signal receiving device 250 is used for receiving signals. When the carrier does not enter between the first clamping jaw 220 and the second clamping jaw 230, the signal emitted by the signal emitting device 240 is not blocked, the signal receiving device 250 can receive the signal emitted by the signal emitting device, and the driving assembly 210 does not drive the first clamping jaw 220 and the second clamping jaw 230 to approach each other; when the carrier enters between the first clamping jaw 220 and the second clamping jaw 230, the signal emitted by the signal emitting device 240 is blocked by the carrier, the signal receiving device 250 cannot receive the signal emitted by the signal emitting device, and the driving assembly 210 drives the first clamping jaw 220 and the second clamping jaw 230 to approach each other.

In a specific implementation, the signal transmitter 240 is an ultrasonic generator, and the signal receiver 250 is an ultrasonic sensor. However, in the embodiment of the present invention, the specific implementation manner of the signal transmitting apparatus 240 and the signal transmitting apparatus is not limited. For example, the signal transmitting device 240 and the signal receiving device 250 may also be a transmitting end and a receiving end of the blocking type photoelectric switch, respectively. Also, for example, the signal transmitting device 240 and the signal receiving device 250 may be a transmitting end and a receiving end of an infrared detection device, respectively.

In a specific implementation, the signal emitting device 240 is disposed at one side of the first positioning wheel 221, and the signal receiving device 250 is disposed at one side of the second positioning wheel 231. When the first positioning wheel 221 and the second positioning wheel 231 are provided with two pairs of time, the signal emitting device 240 is arranged between the two first positioning wheels 221 and fixed on the first transmission piece 222; the signal receiving device 250 is disposed between the two second positioning wheels 231 and fixed to the second transmission member 232. The signal emitting device 240 is installed in the gap between the first positioning wheels 221 and the signal receiving device 250 is disposed in the gap between the two second positioning wheels 231, which can save a design space.

In other embodiments, one of the first clamping jaw 220 and the second clamping jaw 230 may be provided with both the signal transmitting device 240 and the signal receiving device 250, and both the signal transmitting device 240 and the signal receiving device 250 are located below the bottom surface 112. For example, the first jaw 220 is provided with a reflective photoelectric switch such as an infrared photoelectric switch, which detects the presence or absence of an object by using the principle that the object reflects a near-infrared beam and sensing the intensity of the reflected light by a synchronous loop, the photoelectric sensor first emits an infrared beam to reach or penetrate the object or a mirror surface to reflect the infrared beam, and the photoelectric sensor receives the reflected beam and determines whether the object is present according to the intensity of the beam.

The carrying mechanism 10 of the above embodiment, by providing the signal transmitting device 240 and the signal receiving device 250, can realize that the first clamping jaw 220 and the second clamping jaw 230 move close to each other only when a carrier enters between the first clamping jaw 220 and the second clamping jaw 230, and can ensure that the first clamping jaw 220 and the second clamping jaw 230 perform a clamping action when the carrying mechanism 10 moves to the carrier.

The vacuum adsorption mechanism 30 is disposed on the base plate 110. In some embodiments, as shown in fig. 1 and 2, the bottom plate 110 has a slot 114 formed therethrough the top surface 111 and the bottom surface 112. The vacuum absorbing mechanism 30 further comprises a connecting tube 320, the connecting tube 320 is adjustably assembled to the slot 114, wherein one end of the connecting tube 320 is located above the top surface 111, the other end of the connecting tube 320 is located below the bottom surface 112, and the suction cup 310 is connected to the other end of the connecting tube 320. Both ends of the connection pipe 320 protrude from the kidney groove 114. The suction surface 311 of the suction cup 310 is located all the way below the bottom surface 112. One end of the connection pipe 320 is used for connecting a vacuum air pump. The position of the connection pipe 320 is adjustable, and the specific implementation mode is not limited, for example, the connection pipe 320 may be implemented by changing the position of the connection pipe 320 by using a bolt and a nut; the connection pipe 320 may be limited by an elastic structure, and the position of the connection pipe 320 may be adjusted by changing the degree of compression of the elastic structure.

In the above embodiment, the position of the connection pipe 320 in the kidney groove 114 can be adjusted. Specifically, the connection pipe 320 may be moved along the length direction of the kidney groove 114 to change the position of the connection pipe 320 on the base plate 110. After the position of the connection tube 320 on the bottom plate 110 is changed, the position of the suction cup 310 is changed accordingly, so that the display module can be more conveniently sucked. In addition, if the suction surface 311 of the suction cup 310 is set to be located below the bottom surface 112 all the time, when the display module needs to be sucked, the suction can be performed only by starting the vacuum air pump, and the suction cup 310 does not need to be moved downward first, so that the suction efficiency can be improved.

After the display module is placed on the carrier by the suction cup 310, the robot 50 drives the carrying mechanism 10 to move downward, so that the bottom plate 110 presses the display module. In order to avoid crushing the display module, as shown in fig. 1 and 2, in some embodiments, the carrying mechanism 10 further includes a buffer mechanism 50 mounted on the bottom plate 110, and the buffer mechanism 50 has a buffer 510 located below the bottom surface 112. When the carrying mechanism 10 moves downward, the buffer 510 will contact the upper surface of the carrier first, so as to prevent the bottom plate 110 from generating impact to the display module and damage the display module. The damper mechanism 50 may be a hydraulic damper, a spring damper, a urethane damper, or the like.

In the specific arrangement, the bottom plate 110 is rectangular, and the four corners are respectively provided with one buffer mechanism 50. The four buffer mechanisms 50 are uniformly distributed in the circumferential direction, and an annular buffer surface can be established between the base plate 110 and the carrier, so that the base plate 110 is better prevented from generating impact on the display module. It should be noted that the shape of the bottom plate 110 is not limited to the rectangle.

When the display module is attached to the carrier via the suction cup 310, a camera vision positioning system is required. In this process, the positioning position on the display module or the carrier needs to be polished to facilitate alignment. In order to save space, as shown in fig. 1, in some embodiments, the edge of the bottom plate 110 is further provided with a light source 60, and the light emitting direction of the light source 60 faces below the bottom surface 112. That is, the light source 60 is integrated on the base plate 110, and the light can be polished when the carrying mechanism 10 moves to the display module or the carrier, so as to save the design space.

Further, the light source 60 is adjustably positioned on the base plate 110. In this way, the irradiation position of the light source 60 can be changed by adjusting the position of the light source 60 on the base plate 110. Specifically, the irradiation position of the light source 60 can be adjusted, so that light can avoid the electronic components protruding from the display module and irradiate the flat area, and the sucker 310 can be conveniently attached to the display module. The position adjustment can be achieved by providing multiple positions on the base plate 110. If the base plate 110 is provided with a plurality of mounting holes, the position of the light source 60 can be adjusted by fixing the light source 60 in different mounting holes. As another example, the light source 60 may be provided with a waist-shaped hole, and the light source 60 is fixed to the base plate 110 by a bolt and a nut passing through the waist-shaped hole, so that the adjustment of the position of the light source 60 may also be achieved.

As shown in fig. 3 and 4, an embodiment of the present invention provides a product handling apparatus, which includes a robot 50, and the handling mechanism 10 of the foregoing embodiment, wherein the connecting head 120 is fixed to the robot 50. The manipulator 50 is specifically a manipulator 50 of a multi-axis robot, and can realize the motion in the X \ Y \ Z direction in space, and the manipulator 50 further has a rotation degree of freedom to drive the carrying mechanism 10 to rotate.
