The bearing assembly 100 includes a bearing platform 110 and a plug 120. The bearing surface 111 is arranged on the bearing platform 110. The plug 120 can be detachably connected to the bearing platform 110, for example, by a threaded connection. The bearing platform 110 can be roughly rectangular. The first direction, the second direction and the third direction which are arranged at angles to each other are used as references.

[0042] See also Figure 8 , Fig. 9 , Fig.10 and Fig.11 The first adsorption section 141 is connected with the first channel 150 and the second adsorption section 142 at the same time. The first adsorption section 141 can penetrate the bearing surface 111, so that the first adsorption section 141 has a connecting port on the bearing surface 111. By setting the connecting port, it is convenient to process the first adsorption section 141. A plug 120 can be set at the connecting port. When the plug 120 is installed on the bearing platform 110, the plug 120 can block the connecting port to prevent the first adsorption section 141 from communicating with the outside world. When the plug 120 is unloaded from the bearing platform 110, the plug 120 can open the connecting port to allow the first adsorption section 141 to communicate with the outside world.

[0043] The second adsorption section 142 is connected to the first adsorption section 141 and the third adsorption section 143 at the same time. One end of the second adsorption section 142 is connected to the third adsorption section 143, and the middle part of the second adsorption section 142 is connected to the first adsorption section 141. The other end of the second adsorption section 142 may have a connecting port on the side of the carrier 110 in the width direction, that is, the second adsorption section 142 runs through the side, so that the second adsorption is connected to the outside world through the connecting port. By setting the connecting port, it is convenient to process the second adsorption section 142. A plug 120 may be set at the connecting port. When the plug 120 is installed on the carrier 110, the plug 120 can block the connecting port to prevent the second adsorption section 142 from communicating with the outside world. When the plug 120 is unloaded from the carrier 110, the plug 120 can open the connecting port to allow the second adsorption section 142 to communicate with the outside world.

[0044] The third adsorption section 143 is connected to the second adsorption section 142, the fourth adsorption section 144 and the fifth adsorption section 145 at the same time. One end of the third adsorption section 143 is connected to the fourth adsorption section 144 and the fifth adsorption section 145. The middle part of the third adsorption section 143 is connected to the second adsorption section 142. The other end of the third adsorption section 143 may have a connecting port on the side of the carrier 110 in the length direction, that is, the third adsorption section 143 runs through the side, so that the third adsorption is connected to the outside world through the connecting port. By setting the connecting port, it is convenient to process the third adsorption section 143. A plug 120 can be set at the connecting port. When the plug 120 is installed on the carrier 110, the plug 120 can block the connecting port to prevent the third adsorption section 143 from communicating with the outside world. When the plug 120 is unloaded from the carrier 110, the plug 120 can open the connecting port to allow the third adsorption section 143 to communicate with the outside world.

[0045] The fourth adsorption section 144 is connected to the third adsorption section 143 and the fifth adsorption section 145 at the same time, so that one end of the fourth adsorption section 144 is connected to the third adsorption section 143, and one end of the fourth adsorption section 144 passes through the bearing surface 111 to form an adsorption port 146. When the workpiece 20 is placed on the bearing surface 111 and covers the adsorption port 146, when a vacuum is generated in the adsorption chamber 140, the workpiece 20 is adsorbed on the bearing surface 111 under the action of the vacuum, so that the convenient transfer fixture 10 can clamp the workpiece 20. The number of the fourth adsorption section 144 can be multiple, and the caliber of the fourth adsorption section 144 can be smaller than the calibers of the first adsorption section 141, the second adsorption section 142 and the third adsorption section 143.

[0046] The fifth adsorption section 145 is connected to the second channel 160 and the fourth adsorption section 144 at the same time, so that one end of the fifth adsorption section 145 is connected to the third adsorption section 143, and the middle part of the third adsorption section 143 is connected to the second channel 160.

By setting the connecting port, it is convenient to process the fifth adsorption section 145. A plug 120 can be set at the connecting port. When the plug 120 is installed on the carrier 110, the plug 120 can block the connecting port to prevent the fifth adsorption section 145 from communicating with the outside world. When the plug 120 is unloaded from the carrier 110, the plug 120 can open the connecting port to allow the fifth adsorption section 145 to communicate with the outside world.

[0047] See also Figure 4 , Figure 5 , Figure 6 and Figure 7In some embodiments, the first channel 150 may extend along the length direction of the carrier 110, and the loading and unloading mechanism 200 includes a first elastic member 210 and a loading and unloading assembly 220. The first elastic member 210 may be a spring, etc. The first elastic member 210 is pressed between the carrier 110 and the loading and unloading assembly 220 and is located in the first channel 150. The loading and unloading assembly 220 is movably connected to the carrier 110 and can change the length of the loading and unloading assembly 220 into the first channel 150. The loading and unloading assembly 220 includes a guide rod 221 and a sealing member 222. The guide rod 221 is slidably matched with the first channel 150 and abuts against the first elastic member 210. The sealing member 222 is sleeved on the guide rod 221 and abuts against the carrier assembly 100, so that the sealing member 222 can seal the first channel 150.

[0048] See also Figure 4 , Figure 5 , Figure 6 and Figure 7The bearing assembly 100 may further include a stopper 170, which may be detachably connected to the bearing platform 110, for example, the stopper 170 may be fixed to the bearing platform 110 by bolt connection. The first channel 150 includes a sliding section 151 and a guide section 152, wherein the sliding section 151 is located on the bearing platform 110, the guide section 152 is located on the stopper 170, and the first elastic member 210 is located in the sliding section 151. The guide rod 221 includes a sliding portion 2211, a guide portion 2212 and a stopper 2213, wherein the sliding portion 2211, the guide portion 2212 and the stopper 2213 are coaxially arranged, the sliding portion 2211 is slidably matched with the sliding section 151, the guide portion 2212 is slidably matched with the guide section 152, the length of the guide portion 2212 is greater than the length of the guide section 152, and the stopper 2213 is located outside the entire sliding section 151 and the guide section 152. The cross-sectional dimensions of the guide portion 2212 are smaller than the cross-sectional dimensions of the stopper 2213 and the sliding portion 2211, and the stopper 170 can abut against the stopper 2213 or the sliding portion 2211 along the axial direction of the guide rod 221. In the process of pushing the entire guide rod 221 to move close to the first adsorption section 141 through the stopper 2213, the first elastic member 210 generates extrusion and stores energy, and the extension length of the guide rod 221 into the first channel 150 increases. When the stopper 2213 abuts against the stopper 170, the guide rod 221 stops extending into the first channel 150, that is, the extension length of the guide rod 221 in the first channel 150 is the largest, and the effective space of the first channel 150 is the smallest. During the process that the first elastic member 210 releases energy and pushes the entire guide rod 221 to move away from the first adsorption section 141, the extension length of the guide rod 221 into the first channel 150 is reduced. When the sliding portion 2211 abuts against the limit member 170, the guide rod 221 stops extending further out of the first channel 150, that is, the extension length of the guide rod 221 in the first channel 150 is the smallest, and the effective space of the first channel 150 is the largest.

[0049] See also Figure 4 , Figure 5 , Figure 6 and Figure 7When the workpiece 20 needs to be adsorbed on the bearing surface 111, the entire guide rod 221 can be pushed by the stop portion 2213 to overcome the elastic force of the first elastic member 210 and move close to the first adsorption section 141 until the stop portion 2213 abuts against the limit member 170. At this time, the effective space of the first channel 150 is minimized, so that the effective space of the first channel and the adsorption chamber 140 is minimized, and the air will be discharged from the first channel 150 and the adsorption chamber 140. Then the workpiece 20 is placed on the bearing surface 111 and covers the adsorption port 146, and the thrust applied to the stopper 2213 is stopped. At this time, the first elastic member 210 releases energy and pushes the entire guide rod 221 to move away from the first adsorption section 141 until the sliding portion 2211 abuts against the limit member 170, thereby maximizing the effective space of the first channel 150, and also maximizing the effective space of the first channel 150 and the adsorption chamber 140; in this way, the gas expands in the first channel 150 and the adsorption chamber 140, causing the air pressure in the first channel 150 and the adsorption chamber 140 to be less than the atmospheric pressure and a certain degree of vacuum, so the workpiece 20 can be fixed on the bearing surface 111.

[0050] The stopper 2213 is detachably connected to the guide part 2212, for example, the stopper 2213 is bolted to the guide part 2212. During the installation of the guide rod 221, the seal 222 can be firstly sleeved on the sliding part 2211, and the sliding part 2211 can be matched with the sliding section 151 of the first channel 150. Then the guide part 2212 is matched with the guide section 152 of the limiter 170, and the limiter 170 is fixed on the bearing platform 110. Finally, the stopper 2213 is fixedly connected to the guide part 2212. Based on the special structure of the guide rod 221, in order to avoid interference, the stopper 2213 is detachably connected to the guide part 2212, and the limiter 170 is detachably connected to the bearing platform 110, so as to ensure the smooth installation of the guide rod 221.

[0051] See also Figure 2 , Figure 3 , Fig.10 and Fig.11 In some embodiments, the adsorption mechanism 300 includes a second elastic member 310 and a switch member 320. The second elastic member 310 is pressed between the support platform 110 and the switch member 320 and is located in the second channel 160. The switch member 320 can be movably connected to the support platform 110 and can open or close the connection between the second channel 160 and the vacuum chamber in the external vacuum tube.

[0052] See also Figure 2 , Figure 3 , Fig.10 and Fig.11, the bearing assembly 100 may also include a plug 130, and the plug 130 can be detachably connected to the bearing platform 110, for example, the detachable connection can be achieved by a threaded connection. The second channel 160 is located on the bearing platform 110 and can extend along the height direction of the bearing platform 110, and both ends of the second channel 160 can be connected to the outside world. The second channel 160 includes a receiving section 161 and a conducting section 162, and the receiving section 161 and the conducting section 162 can be coaxially arranged. The caliber of the receiving section 161 is larger than the caliber of the conducting section 162. The receiving section 161 passes through the bearing surface 111, so the receiving section 161 has an opening on the bearing surface 111 that is connected to the outside world. Therefore, the end of the receiving section 161 is connected to the outside world, and the middle of the receiving section 161 is connected to the fifth adsorption section 145. The conducting section 162 passes through the surface opposite to the bearing surface 111, so that the conducting section 162 has an opening on the surface that is connected to the outside world. There is a step surface 163 between the receiving section 161 and the conducting section 162, and the step surface 163 is arranged around the conducting section 162. By arranging an opening on the bearing surface 111, the second channel 160 can be easily processed. When the plug 130 is installed on the bearing platform 110, the plug 130 can block the opening of the receiving section 161, thereby preventing the first channel 150 from communicating with the outside. When the plug 130 is unloaded from the bearing platform 110, the plug 130 can open the opening of the receiving section 161, thereby allowing the second channel 160 to communicate with the outside.

[0053] See also Figure 2 , Figure 3 , Fig.10 and Fig.11, the switch member 320 is movably arranged in the receiving section 161, so that the switch member 320 can slide in the receiving cavity, and the switch member 320 can be a sphere. The diameter of the switch member 320 can be smaller than the diameter of the receiving section 161 and larger than the diameter of the conducting section 162, so when the switch member 320 abuts against the step surface 163, the switch member 320 can block the end of the conducting section 162, thereby preventing the conducting section 162 and the receiving section 161 from being connected to each other. The second elastic member 310 can be a spring, etc., and the second elastic member 310 abuts between the plug 130 and the switch member 320. In the absence of external force acting on the switch member 320, under the action of the elastic force generated by the second elastic member 310, the switch member 320 can abut against the step surface 163, so that the switch member 320 blocks the conducting section 162. When the convenient transfer fixture 10 is placed on the inspection machine, the vacuum tube on the inspection machine can be inserted into the conducting section 162 and extend into the receiving section 161, so that the vacuum tube on the inspection machine overcomes the elastic force of the second elastic member 310 to apply a pushing force to the switch member 320, so that the switch member 320 moves away from the step surface 163, thereby making the conducting section 162 and the receiving section 161 connected to each other, and then making the vacuum cavity in the vacuum tube connected to the receiving section 161 through the conducting section 162, and finally making the conducting section 162, the receiving section 161, the fifth adsorption section 145 and the fourth adsorption section 144 connected to each other. When a vacuum is generated in the vacuum cavity, a vacuum will be generated in the fourth adsorption section 144, so that the workpiece 20 is fixed on the bearing surface 111 through the vacuum adsorption force generated by the adsorption port 146.

[0054] See also Figure 2 , Figure 3 , Fig.10 and Fig.11 In some embodiments, the adsorption mechanism 300 may further include a sealing pad 330, which has a certain flexibility and is an annular structure. The sealing pad 330 is located in the receiving section 161 and is arranged on the step surface 163. The switch member 320 is abutted between the sealing pad 330 and the second elastic member 310. When the switch member 320 abuts against the sealing pad 330, the switch member 320 will block the conduction section 162. When the switch member 320 leaves the sealing pad 330, the switch member 320 will open the conduction section 162, so that the conduction section 162 and the receiving section 161 are connected to each other. By providing the sealing pad 330, on the one hand, it can play a good buffering role to prevent a large impact force from being generated between the switch member 320 and the step surface 163. On the other hand, when the switch member 320 abuts against the sealing pad 330, the sealing performance of the switch member 320 on the conduction section 162 can be improved to prevent liquid and dust from entering the conduction section 162 and the receiving section 161.

[0055] See also Figure 2 , Figure 3 , Fig.10 and Fig.11 In some embodiments, a countersunk hole 180 may be provided on the surface of the carrier 110 that is opposite to the carrier surface 111, and the countersunk hole 180 is connected to the conductive section 162. When the convenient transfer fixture 10 is placed on the detection machine, the protruding structure on the detection machine can cooperate with the countersunk hole 180, thereby improving the positioning accuracy of the convenient transfer fixture 10 on the detection machine.

[0056] See also Figure 6 , Figure 7 and Figure 8 In some embodiments, the convenient transfer fixture 10 may further include a positioning member 400. The positioning member 400 may be a plate-like structure. The positioning member 400 may be detachably connected to the carrier 110 by bolt connection. The positioning member 400 may be stacked on the carrier surface 111. A positioning hole 410 is provided on the positioning member 400. The shape of the positioning hole 410 matches the shape of the workpiece 20. When the workpiece 20 is placed on the carrier surface 111, the workpiece 20 will also cooperate with the positioning hole 410. The inner wall surface of the positioning hole 410 will abut against the workpiece 20, thereby playing a good positioning role for the workpiece 20 and providing positioning accuracy and clamping reliability for the workpiece 20.

[0057] See also Figure 3 , Figure 4 and Fig. 9, the working principle of the convenient transfer fixture 10 is introduced below: the first step is to place the convenient transfer fixture 10 outside the inspection machine. The stopper 2213 pushes the guide rod 221 to overcome the elastic force of the first elastic member 210 and gradually extend into the first channel 150, so that the extension length of the guide rod 221 in the first channel 150 increases and the gas in the first channel 150 is discharged, thereby greatly reducing the effective space of the first channel 150 for accommodating gas. Then, place the workpiece 20 on the bearing surface 111 and cover the suction port 146. It can be observed through a microscope to ensure that the workpiece 20 is placed on the bearing surface 111 with the correct posture. Then stop applying thrust to the stopper 2213. At this time, the first elastic member 210 will push the guide rod 221 to gradually extend out of the first channel 150, so that the extension length of the guide rod 221 in the first channel 150 is reduced, the effective space of the first channel 150 for accommodating gas is increased, and the volume of gas in the first channel 150 and the adsorption chamber 140 is increased, so that a certain vacuum degree is generated in the first channel 150 and the entire adsorption chamber 140, and then the workpiece 20 is adsorbed on the bearing surface 111. At this time, the fixation of the workpiece 20 can be understood as pre-fixation. Of course, during the entire process that the convenient transfer fixture 10 is located outside the detection machine, under the action of the second elastic member 310, the switch member 320 will always block the conduction section 162, so that the adsorption chamber 140 cannot be connected to the outside world through the second channel 160, thereby maintaining a reasonable vacuum degree in the adsorption chamber 140.

[0058] In the second step, the convenient transfer fixture 10 is placed on the detection machine. At this time, the vacuum tube of the detection machine will be inserted into the conductive section 162 and extended into the receiving section 161, so that the vacuum tube on the detection machine overcomes the elastic force of the second elastic member 310 to apply a pushing force to the switch member 320 and move away from the step surface 163, so that the conductive section 162 and the receiving section 161 are connected to each other, and then the vacuum chamber in the vacuum tube is connected to the adsorption chamber 140 through the second channel 160, which will further increase the vacuum degree in the adsorption chamber 140, thereby improving the adsorption force of the workpiece 20, so that the workpiece 20 can be stably and reliably carried on the convenient transfer fixture 10 for detection by the detection machine. At this time, the fixation of the workpiece 20 can be understood as complete fixation.

[0059] The third step is to unload the convenient transfer fixture 10 from the inspection machine after the inspection of the workpiece 20 is completed. At the moment of unloading the convenient transfer fixture 10, the second elastic member 310 will push the switch member 320 to block the conduction section 162 to prevent the adsorption chamber 140 from communicating with the outside world. At this time, the adsorption chamber 140 still has a certain degree of vacuum, which will fix the workpiece 20 on the convenient transfer fixture 10 with a reasonable adsorption force, and prevent the workpiece 20 from detaching from the convenient transfer fixture 10 during the transfer of the convenient transfer fixture 10. After the convenient transfer fixture 10 is transferred to the specified position, the guide rod 221 can be pushed by the stopper 2213 to gradually extend into the first channel 150, thereby increasing the air pressure in the adsorption chamber 140, thereby releasing the vacuum of the adsorption chamber 140, and finally unloading the workpiece 20 from the convenient transfer fixture 10 after the inspection is completed.

[0060] Since the workpiece 20 can be fixed on the convenient transfer fixture 10 outside the detection machine, interference with the detection machine can be avoided, and workpieces 20 such as chips can be prevented from falling on the detection machine and causing damage, ensuring that the workpiece 20 is smoothly placed on the bearing surface 111 in an accurate posture, thereby improving the clamping efficiency of the workpiece 20, and ultimately improving the convenience of using the convenient transfer fixture 10. At the same time, it only needs to push the guide rod 221 to fix it, and there is no need to install an additional vacuum tube on the convenient transfer fixture 10, further improving the convenience of using the convenient transfer fixture 10. In addition, the convenient transfer fixture 10 itself does not have a vacuum tube, which further improves the convenience of use on the basis of simplifying the structure of the convenient transfer fixture 10.
