According to an embodiment of the present invention, as seen in conjunction with the illustrations of fig. 1 and 2, an assembly apparatus comprising:

the conveying line body 21 is provided with a feeding station and a pressure maintaining station in sequence along the conveying direction;

the assembling component 23 is used for grabbing a workpiece and transferring the workpiece to the feeding station; and

a detection assembly 22 located on a moving path of the assembly 23 for grasping the workpiece;

the conveying line body 21 is used for conveying carriers, a positioning support 212 and a pressure maintaining assembly 25 are arranged on the conveying line body 21 to correspond to the feeding station and the pressure maintaining station, the positioning support 212 is used for limiting the positions of the carriers, and the assembling assembly 23 grabs workpieces and then transfers the workpieces to the carriers on the positioning support 212;

specifically, the positioning bracket 212 is located on the transmission line body 21, the positioning bracket 212 is close to the upstream end of the transmission line body 21, an assembly hole penetrating through the positioning bracket 212 from top to bottom is formed in the top of the positioning bracket 212, a lifting module is further arranged on the transmission line body 21, the lifting module is located right below the assembly hole, and the carrier on the transmission line body 21 is pushed by the lifting module, so that the carrier is separated from the transmission line body 21 and gradually approaches to the top of the positioning bracket 212;

when the lifting module lifts the carrier conveyed on the conveying line body 21 to abut against the top of the positioning bracket 212, the mounting position on the carrier corresponds to the position of the assembly hole of the positioning bracket 212, so that the assembly component 23 can pass through the assembly hole to place the workpiece on the carrier.

The detecting assembly 22 includes an upper detecting portion 221 and a lower detecting portion 224, the lower detecting portion 224 is disposed near the positioning bracket 212, the upper detecting portion 221 is located above the positioning bracket 212, the upper detecting portion 221 detects the carrier through the mounting hole, the upper detecting portion 221 and the lower detecting portion 224 include a visual detector and a driver for adjusting the focal length;

it should be noted that, since the assembly component 23 passes through the assembly hole to place the workpiece on the carrier, and the upper detection portion 221 detects the carrier through the assembly hole, interference between the assembly component 23 and the upper detection portion 221 is likely to occur during operation, collision between the assembly component 23 and the upper detection portion 221 is likely to occur, which results in failure of the machining process, and even more, damage to the assembly component 23 and the upper detection portion 221;

in order to avoid the above problem, when the carrier position needs to be detected, the upper detection portion 221 is driven by a linear driver 223, so that the upper detection portion 221 moves to a position right above the positioning bracket 212, and after the detection, the upper detection portion 221 moves away from the positioning bracket 212, so as to give way to the assembly component 23, thereby ensuring the normal use of the assembly device.

The detection assembly 22 further comprises a gantry 222, which is closely disposed at the positioning bracket 212; the linear driver 223 is installed on the gantry 222, and the upper detection part 221 is installed on the power output end of the linear driver 223; the linear driver 223 drives the upper detection part 221 to reciprocate along a linear direction, and the upper detection part 221 can move to the position right above the assembly hole;

the gantry 222 is located at one side of the conveyor line body 21, and a driving direction of the linear driver 223 is parallel to a conveying direction of the conveyor line body 21, so that the upper detection part 221 moves along the conveying direction of the conveyor line body 21;

the upper detection part 221 and the lower detection part 224 respectively detect the carrier and the workpiece captured on the assembly component 23, wherein specifically, after the workpiece captured by the assembly component 23 passes above the lower detection part 224, the lower detection part 224 detects the workpiece on the assembly component 23, so as to ensure the position of the workpiece, and meanwhile, the upper detection part 221 positions the position of the carrier, so that the assembly precision is improved;

further, after the assembly is completed, the upper detection part 221 is driven by the linear driver 223 to move to the loading station again, and the position of the workpiece on the loading tool is detected to detect the assembly quality, so that the workpiece processed by the assembly device has higher precision.

The assembling device further comprises a film tearing assembly 24, wherein the workpiece is coated with a film, the film tearing assembly 24 clamps the film and peels the film from the workpiece when the assembling assembly 23 is far away from the film tearing assembly 24, and the film tearing assembly 24 is positioned on a moving path of the assembling assembly 23 for grabbing the workpiece;

the workpiece grabbed by the assembling component 23 moves to the position of the film tearing component 24, the film tearing component 24 clamps the film, and the film is peeled off from the workpiece along with the assembly component 23 driving the workpiece to be far away from the film tearing component 24.

In a preferred embodiment, the film tearing assembly 24 and the detecting assembly 22 are disposed on two corresponding sides of the transmission line body 21, and the assembling assembly 23 is located on the same side of the transmission line body 21 on which the film tearing assembly 24 is disposed, so as to avoid interference between the assembling assembly 23 and the upper detecting portion and/or the gantry 222 during movement, and meanwhile, the assembling device is disposed on two sides of the transmission line body 21 to reasonably utilize space, so that the assembling device is more compact.

In a preferred embodiment, the assembly 23 includes a robot arm and a suction nozzle mounted on a power output end of the robot arm, the suction nozzle being moved by the robot arm, the suction nozzle being configured to suck a workpiece.

a stopping part 213 is arranged between the two transmission parts 211, the stopping part 213 is correspondingly arranged at the material loading station and the pressure maintaining station, and the carrier moving on the transmission parts 211 is limited by the stopping part 213, so that the carrier is limited at the material loading station or the pressure maintaining station.

The number of the pressure maintaining assemblies 25 is not less than two, and the two pressure maintaining assemblies 25 are sequentially arranged on the transmission line body 21 along the transmission direction of the transmission line body 21.

In the process of using the assembling device, because the time consumed in the process that the assembling component 23 grabs the workpiece and tears the film off and installs the film in the carrier is less than the time required by the pressure maintaining component 25 for maintaining the pressure of the workpiece on the carrier, if the pressure maintaining component 25 does not complete the pressure maintaining, the carrier assembled with the workpiece processed by the assembling component 23 is accumulated on the transmission line 21 between the positioning bracket 212 and the pressure maintaining component 25, and the number of the accumulated carriers is gradually increased, in order to avoid the situation of large accumulation, the pressure maintaining is carried out on the two carriers by the two pressure maintaining components 25, so that the carrier processed by one assembling component 23 corresponds to the two pressure maintaining components 25, the layout is optimized, the pressure maintaining is matched with the assembling processing, the production efficiency is improved, and the production ratio is higher.

In a preferred embodiment, the pressure maintaining assembly 25 comprises: a connecting seat 252 having a top end provided with a limiting surface 2521 for receiving a workpiece; and

the pressing portion 251 is located above the limiting surface 2521;

correspondingly, the pressing portion 251 includes a pressing head module 2511 and at least two groups of weight modules 2513, the weight modules 2513 press down on the top end of the pressing head module 2511, so that the pressing head module 2511 presses down on the workpiece, thereby driving the workpiece to adjust from an inclined state to a balanced state;

In the process of assembling the workpiece, due to the shape of the workpiece, the assembling position is not at an ideal position, a pressing mechanism is needed to press and adjust the position of the workpiece, and meanwhile, the workpiece is connected more stably in a pressure maintaining mode; when a workpiece is assembled, the workpiece can be in an inclined state or a balanced state, the inclined state is that the workpiece is inclined relative to a pressing surface of the pressing head module 2511, so that the contact area between the workpiece and the pressing head module 2511 is small, the balanced state is that the levelness of the workpiece is consistent with the pressing surface of the pressing head module 2511, when the workpiece is in the balanced state, the assembling device performs pressure maintaining on the workpiece, and when the workpiece is in the inclined state, the counterweight module 2513 presses the pressing head module 2511 down so that the pressing head module 2511 presses down at an inclined vertex of the workpiece, so that the workpiece is driven to deflect to the balanced state; when the workpiece is in a balanced state, each set of the weight modules 2513 acts on the corresponding region of the pressing head module 2511 for pressing the workpiece.

The specific pressure maintaining principle comprises the following steps: when the workpiece is in an inclined state, as shown in fig. 12, the top position of the workpiece inclination is a position abutting against the pressing head module 2511, and at this time, because the two counterweight modules 2513 press down on the pressing head module 2511, the gravity borne by the position of the workpiece abutting against the pressing head module 2511 is the gravity sum G of the two counterweight modules 2513, and the supporting force F of the position of the workpiece abutting against the pressing head module 2511 to the pressing head module 2511 is_NIn line with G, the ram block 2511 thus applies to the workpiece in an abutting position when the workpiece is in an inclined conditionThe force is greater so that the workpiece can be deflected to an equilibrium state under the urging of the force.

When the workpiece is in a balanced state, as shown in fig. 13, since the center line of gravity of each set of the weight modules 2513 is located outside the pressure maintaining block 25112, the gravity g of each set of the weight modules 2513 corresponds to the supporting force F of the part of the pressure maintaining block 25112 in contact with the workpiece_NSo that the two weight modules 2513 respectively apply acting forces to the two parts of the pressure maintaining block 25112, and the gravity acting on the pressure maintaining block 25112 is G, wherein G is>g; therefore, when the workpiece is in different states, the gravity of the counterweight module 2513 on the workpiece is different, so as to meet different pressures required in the process of adjusting the position of the workpiece or maintaining the pressure.
