[0035] Reference below Figures 1 to 5 A PCB handling jig according to an embodiment of the first aspect of the utility model is described in detail.

[0036] According to some embodiments of the present invention, a PCB handling fixture includes a mounting frame 100, an adsorption assembly 200 and a clamping assembly 300. The mounting frame 100 includes two frames 110 distributed along a first direction; each frame 110 is provided with at least one adsorption assembly 200, and the adsorption assembly 200 includes an adsorption member 210, and the adsorption surfaces 210a at the lower ends of the adsorption members 210 are coplanar and are used to adsorb process ends on opposite sides of the same PCB; each frame 110 is provided with at least one clamping assembly 300, and the clamping assembly 300 includes an adjustment structure 3 10 and a clamping structure 320, the clamping structure 320 is provided with a clamping area 320a, the clamping area 320a can accommodate the process end of the PCB, the adjusting structure 310 is connected to the clamping structure 320, and is used to switch the clamping structure 320 between the working position and the avoidance position, when the clamping structure 320 is in the working position, the plane where the adsorption surface 210a is located passes through the clamping area 320a, so that the clamping structure 320 can clamp the PCB adsorbed by the adsorption member 210, and when the clamping structure 320 is in the avoidance position, the clamping structure 320 is located as a whole on the upper side of the adsorption surface 210a.

[0037] refer to Figures 1 to 4 In some embodiments of the present invention, a PCB handling fixture includes a mounting frame 100, a plurality of adsorption components 200 and a plurality of clamping components 300. The mounting frame 100 includes two frames 110 arranged in parallel and spaced apart along a first direction. Each frame 110 is provided with a plurality of adsorption components 200 spaced apart along the extension direction of the frame 110. The adsorption components 200 include an adsorption member 210. The lower end of the adsorption member 210 is provided with an adsorption surface 210a. The adsorption surfaces 210a are all at On the same plane; two clamping assemblies 300 are arranged on each frame 110, and each clamping assembly 300 is arranged between two adjacent adsorption assemblies 200. The clamping assembly 300 includes an adjusting structure 310 and a clamping structure 320. The clamping structure 320 is provided with a clamping area 320a, and the clamping area 320a can accommodate the process end of the PCB. The adjusting structure 310 is connected to the clamping structure 320 and is used to switch the clamping structure 320 between the working position and the avoidance position.

[0038] During the use of the PCB handling jig of the present application, when the clamping structure 320 is in the avoidance position, the clamping structure 320 is located as a whole on the upper side of the adsorption surface 210a. At this time, the PCB handling jig only adsorbs the process ends of the opposite sides of the PCB through the adsorption components 200 arranged on the two frames 110, thereby transporting the PCB. When the clamping structure 320 needs to be used, the adjustment structure 310 in the clamping component 300 is used to make the clamping structure 320 located in the working position. At this time, the PCB is located in the clamping area 320a of the clamping structure 320, and the clamping structure 320 can clamp the process end of the PCB adsorbed by the adsorption component 210. From the above working process, it can be known that when the adsorption component 200 is difficult to stably adsorb a larger PCB board, the PCB handling jig can move the clamping structure 320 downward by adjusting the structure 310, so that the PCB is placed in the clamping area 320a, and on the premise that the adsorption component 210 adsorbs the process end of the PCB, the process end of the PCB is further clamped by the clamping structure 320, so that the PCB handling jig can transport the PCB more stably.

[0039] It can be understood that when stable transportation of the PCB can be achieved by only using multiple adsorption components 200 to adsorb the process end of the PCB, the clamping structure 320 is positioned above the adsorption surface 210a through the adjustment structure 310 of the clamping component 300, thereby preventing the clamping structure 320 from interfering with the adsorption component 200 when the adsorption component 200 adsorbs the PCB.

[0040] like Figure 1 and Figure 3 As shown, in some embodiments, the adjustment structure 310 includes a first driver, which is disposed on the frame 110 and connected to the clamping structure 320. The first driver can drive the clamping structure 320 to move along a second direction perpendicular to the adsorption surface 210a, and the second direction is spaced apart from the first direction at a certain angle. It can be understood that since the second direction is spaced apart from the first direction at a certain angle, the clamping structure 320 is moved along the second direction by the first driver, so that the clamping structure 320 is switched between the working position and the avoidance position, thereby realizing the switching of the two working states of the PCB handling fixture.

[0041] In some embodiments, a PCB handling fixture further includes an adjustment component 400, which is connected to at least one frame 110 and is used to adjust the relative positions of the two frames 110 in the first direction. Figure 1 and Figure 2As shown, a PCB handling fixture also includes an adjustment component 400, and the adjustment component 400 includes a third driver, which is arranged on the mounting frame 100 and connected to one of the frames 110. The third driver can drive one of the frames 110 to approach or move away from the other frame 110, thereby adjusting the distance between the two frames 110. It can be understood that when the clamping structure 320 is located in the working position through the adjustment structure 310, and the plane where the adsorption surface 210a is located passes through the clamping area 320a, the PCB is between the two frames 110, and one of the frames 110 is brought close to the process end of one side of the PCB through the third driver until the process end of the PCB is in the clamping area 320a, at which time the clamping structure 320 can clamp the process end of the PCB.

[0042] like Figure 3 As shown, in one embodiment of the utility model, the clamping structure 320 includes a first clamping block 321, a second clamping block 322 and a second driver 323. The first clamping block 321 and the second clamping block 322 are distributed along the second direction. A clamping area 320a for accommodating the PCB process end is formed between the first clamping block 321 and the second clamping block 322. The second driver 323 is connected to the first clamping block 321 and is used to drive the first clamping block 321 to approach or move away from the second clamping block 322. It can be understood that when the process end of the PCB is in the clamping area 320a, the second driver 323 drives the first clamping block 321 to approach the second clamping block 322 along the second direction until the first clamping block 321 and the second clamping block 322 respectively abut the process end of the PCB, thereby achieving the clamping of the PCB by the clamping structure 320. Conversely, the second driver 323 drives the first clamping block 321 to move away from the second clamping block 322 along the second direction, so that the clamping structure 320 releases the process end of the PCB, and then the PCB can be separated from the PCB handling fixture through the adjustment component 400.

[0043] refer to Figure 1 and Figure 4 In some embodiments of the present invention, the adsorption assembly 200 further includes a vacuum generator 220. In the same adsorption assembly 200, the adsorption piece 210 corresponds to and is connected with the vacuum generator 220. It can be understood that since a plurality of vacuum generators 220 and a plurality of adsorption pieces 210 are provided, and the adsorption pieces 210 correspond to and are connected with the vacuum generator 220, the staff can control the working state of the vacuum generator 220 to achieve individual adjustment of the adsorption force between each adsorption piece 210 and the PCB, which is conducive to achieving precise control of the suction force applied to each area of ​​the PCB.

[0044] like Figure 1 and Figure 4As shown, in one embodiment, an air channel 111 is provided on the frame 110, and in the adsorption assembly 200 provided on the same frame 110, each vacuum generator 220 is connected to the same air channel 111. It can be understood that by connecting the vacuum generator 220 to the air channel 111, the gas is transported into the vacuum generator 220, and under the operation of the vacuum generator 220, a negative pressure is generated. Since the negative pressure port is connected to the adsorption member 210, the adsorption member 210 generates a suction force capable of adsorbing the PCB process end. By providing the air channel 111 on the frame, it is not necessary to add other structures to supply air to the vacuum generator 220, and the overall structure is also simpler.

[0045] In some embodiments of the present invention, Figure 4 As shown, the adsorbent 210 includes an air guide rod 211 and a flexible suction head 212 that can be deformed under the action of an external force. The flexible suction head 212 is arranged at the lower end of the air guide rod 211 and is connected to the air guide rod 211. The lower end adsorption port of the flexible suction head 212 forms an adsorption surface 210a. The other end of the air guide rod 211 is used to communicate with the vacuum generator 220. It can be understood that in order to enable the adsorbent 210 to adsorb the PCB, the staff operates the PCB handling fixture to move down and make the flexible suction head 212 abut against the PCB board. At this time, the air pressure in the air guide rod 211 is negative pressure under the action of the vacuum generator 220, and the flexible suction head 212 is compressed, so that the process end of the PCB can be adsorbed on the flexible suction head 212. The staff further operates the PCB handling fixture to move up, so that the PCB moves down under the action of gravity. Due to the good adsorption between the flexible suction head 212 and the PCB, the flexible suction head 212 is stretched accordingly. By providing a flexible suction head, when the suction piece and the PCB come into contact, the impact force generated can be buffered, thereby reducing the possibility of deformation of the suction piece and the PCB.

[0046] In a further embodiment of the present invention, Figure 4 As shown, the adsorption component 200 also includes an elastic member 230 and a mounting block 240, and the mounting block 240 is connected to the frame 110. On the same adsorption component, the adsorption component 210 and the mounting block 240 are slidably connected, and the elastic member 230 connects the mounting block 240 and the adsorption component 210. It can be understood that in order to enable the adsorption component 210 to adsorb the PCB process end, the staff operates the PCB handling fixture to move downward and make the lower end of the adsorption component 210 abut against the PCB process end. By setting the elastic member 230, the possibility of collision and deformation between the adsorption component 200 and the PCB during abutment is reduced.

[0047] refer to Figure 1 and Figure 5In one embodiment of the utility model, a detection component 500 is also included. The detection component 500 includes a mounting seat 510, an elastic buffer 520 and a pressure sensor 530. The mounting seat 510 is arranged on the mounting frame 100. The pressure sensor 530 can be slidably connected to the mounting seat 510 along the second direction. The opposite ends of the elastic buffer 520 are respectively connected to the mounting seat 510 and the pressure sensor 530. The sensing end of the pressure sensor 530 is located on the upper side of the plane where the adsorption surface 210a is located, and can be abutted against the process end of the PCB adsorbed by the adsorption member 210.

[0048] It is understandable that the staff operates the PCB handling jig to move down and make the flexible suction head 212 abut against the process end of the PCB. At this time, the sensing end of the pressure sensor 530 abuts against the process end of the PCB. In order to make the flexible suction head 212 fit well with the process end of the PCB, the PCB handling jig as a whole continues to move down to compress the flexible suction head 212, and the pressure sensor 530 slides along the second direction, so that the elastic buffer 520 is compressed to store elastic potential energy. After that, the staff operates the PCB handling jig as a whole to move up, and the sensing end of the pressure sensor 530 moves downward under the elastic force provided by the elastic buffer 520. If the flexible suction head 212 and the adsorbent 210 are well adsorbed and attached, the sensing end of the pressure sensor 530 stops moving when it moves down to a certain stroke, and the force value between the sensing end and the process end of the PCB reaches the target value. If there is a gap in the adsorption and attachment between the flexible suction head 212 and the adsorbent 210, the value of the pressure sensor 530 is lower than the target value. Therefore, by setting the detection component 500, it is more conducive to timely judgment of the adsorption condition of the adsorption component 200.

[0049] In some embodiments, a first sensor 600 is further included. The first sensor 600 is disposed on the mounting frame 100 and is used to detect whether there is a PCB on the lower side of the plane where the adsorption surface 210a is located. Figure 1 and Figure 2 As shown, a PCB handling fixture also includes two first sensors 600, which are respectively arranged on two frames 110. The two first sensors 600 are metal sensors. By detecting the metal parts on the PCB board, it is determined whether there is a PCB on the lower side of the plane where the adsorption surface 210a is located.

[0050] It is understandable that, in addition to the metal sensor in the above embodiment, the first sensor 600 may also use a visual sensor or other sensor that can determine whether there is a PCB on the lower side of the plane where the adsorption surface 210a is located in some other embodiments.

[0051] The following describes a handling device according to an embodiment of the second aspect of the utility model. The handling device according to the embodiment of the second aspect of the utility model includes a PCB handling jig according to the above-mentioned embodiment of the first aspect. By using the above-mentioned PCB handling jig in the handling device, when a large-size PCB needs to be handled, it is only necessary to adjust the structure 310 so that the clamping structure 320 is located in the working position, and the PCB is located in the clamping area 320a of the clamping structure 320. While the process end of the PCB is adsorbed by the adsorption component 200, the clamping structure 320 can also clamp the process end of the PCB adsorbed by the adsorption component 210, so that the handling device can handle the PCB more stably.

[0052] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
