[0028] Referring to Figure 1 , Figure 2 and Figure 3In an embodiment of the present application, a bearing device 10 is provided for bearing a carrier 20. A first direction, a second direction and a third direction are taken as reference, the first direction, the second direction and the third direction are perpendicular to each other, at this time, the first direction, the second direction and the third direction are the extension directions of the three coordinate axes in a spatial orthogonal coordinate system. The first direction and the second direction can be horizontal directions, and the third direction can be a vertical direction. The bearing device 10 comprises a base 100, a sliding mechanism 200 and a turnover mechanism 300. The sliding mechanism 200 comprises a sliding unit 210 and a first driver 220, the sliding unit 210 is connected with the base 100, and the sliding unit 210 is used for fixing the carrier 20. The first driver 220 is arranged on the base 100, and the first driver 220 drives the sliding unit 210 to slide along the first direction. The turnover mechanism 300 comprises a turnover unit 310 arranged on the base 100, and the turnover unit 310 is used for rotating the carrier 20 around an axis extending in the first direction.
[0029] If a plurality of articulated mechanical hands are used to bear the carrier 20, the mechanical hands can have a plurality of degrees of freedom of movement, so that the carrier 20 has a plurality of degrees of freedom of movement, and then the mechanical hands meet the diversity of functions, which will lead to the complexity of the structure of the mechanical hands.
[0030] For the bearing device 10 in the above embodiment, when the carrier 20 is fixed on the sliding unit 210, the first driver 220 can drive the sliding unit 210 to move linearly along the first direction. And when the carrier 20 is fixed on the turnover unit 310, the turnover unit 310 can rotate the carrier 20 around an axis extending in the first direction. In this way, the carrier 20 can not only move linearly along a straight line extending in the first direction, but also rotate around a straight line extending in the first direction, so that the carrier 20 has a plurality of degrees of freedom of movement, thereby making the bearing device 10 meet the diversity of functions. At the same time, the structure of the turnover mechanism 300 and the sliding mechanism 200 is simple, and finally the bearing device 10 is more simple in structure.
[0031] Referring to Figure 1 , Figure 2 and Figure 3 , in some embodiments, the base 100 comprises a bottom plate 110 and a guide side plate 120, the number of the guide side plates 120 is two, the two guide side plates 120 are arranged on the bottom plate 110 in a spaced manner, so that the guide side plates 120 are arranged on the bottom plate 110 in a protruding manner along the third direction. A guide rail is arranged on an end of the guide side plate 120 away from the bottom plate 110, the sliding unit 210 is slidingly connected with the two guide rails, so that the sliding unit 210 is slidingly connected with the two guide side plates 120 along the first direction at the same time.
[0032] Referring to Figure 1 ,Figure 2 And Figure 3 In some embodiments, the sliding unit 210 comprises a sliding piece 211 and a clamping piece 212, the sliding piece 211 comprises a sliding part 2111 and a connecting part 2112, the number of the sliding part 2111 is two, the two sliding parts 2111 are arranged in the second direction, and the two sliding parts 2111 are respectively connected with different guide side plates 120 in the first direction. The connecting part 2112 extends in the second direction for a certain length, so that the two ends of the connecting part 2112 are respectively connected with different sliding parts 2111. The clamping piece 212 is fixedly arranged on the sliding part 2111, and the clamping piece 212 is used for clamping the carrier 20, so as to realize the fixing function of the sliding unit 210 to the carrier 20. In other embodiments, the two ends of the connecting part 2112 can be simultaneously connected with different guide side plates 120, and the clamping piece 212 can be fixed on the connecting part 2112, so as to realize the fixing function of the sliding unit 210 to the carrier 20.
[0033] In some embodiments, the number of the clamping piece 212 can be two, the two clamping pieces 212 are arranged in the second direction, and the two clamping pieces 212 are respectively fixed on different sliding parts 2111. The two clamping pieces 212 respectively clamp different positions on the carrier 20, so as to realize the fixing function of the sliding unit 210 to the carrier 20. The clamping piece 212 can be a clamping air cylinder, and the clamping jaws of the clamping air cylinder clamp the carrier 20. In other embodiments, the clamping piece 212 can also fix the carrier 20 by means of buckling or the like.
[0034] Referring to Figure 1 , Figure 2 and Figure 3 In some embodiments, the first driver 220 further comprises a motor 221, a first transmission belt 222, a rotating shaft 223, a second transmission belt 224 and a transmission wheel 225. The motor 221 can be fixed on the bottom plate 110, the rotating shaft 223 is arranged on the two guide side plates 120, the two ends of the rotating shaft 223 are rotatably connected with the guide side plates 120, and most of the rotating shaft 223 is located in the interval space 121 between the two guide side plates 120. The first transmission belt 222 is sleeved on the motor 221 and the rotating shaft 223 at the same time, for example, the first transmission belt 222 is sleeved on the rotating shaft 223 and the output shaft of the motor 221 at the same time. The first transmission belt 222 can be sleeved on the middle part of the rotating shaft 223, so that the stress of the rotating shaft 223 is more balanced, and vibration of the rotating shaft 223 during rotation is avoided. When the output shaft of the motor 221 rotates, the torque of the motor 221 is transmitted to the rotating shaft 223 through the first transmission belt 222, so as to drive the rotating shaft 223 to rotate.
[0035] Referring to Figure 1 , Figure 2 and Figure 3The transmission wheel 225 is arranged on the guide side plate 120, and the number of the transmission wheel 225 can be multiple. The number of the second transmission belt 224 is two, so that the second transmission belt 224 and the two guide side plates 120 form a one-to-one correspondence relationship. For example, one of the second transmission belt 224 is sleeved on one end of the rotating shaft 223 and the transmission wheel 225 of one of the guide side plates 120, and the other second transmission belt 224 is sleeved on the other end of the rotating shaft 223 and the transmission wheel 225 of the other guide side plate 120. The tight side and the loose side of the second transmission belt 224 can move linearly along the first direction. The two sliding parts 2111 of the sliding part 211 can be fixedly connected with different second transmission belts 224, for example, the sliding part 2111 can be fixedly connected with the tight side or the loose side of the second transmission belt 224. Therefore, when the motor 221 drives the rotating shaft 223 to rotate through the first transmission belt 222, the rotating shaft 223 drives the tight side and the loose side of the second transmission belt 224 to move linearly along the first direction, so that the sliding unit 210 moves linearly along the first direction with the tight side or the loose side of the second transmission belt 224. It can be understood that when the motor 221 rotates forward and reversely, the second transmission belt 224 can drive the sliding unit 210 to move reciprocatingly linearly along the first direction. In other embodiments, the first driver 220 can be replaced by a linear module, so that the linear module drives the sliding to move reciprocatingly linearly along the first direction.
[0036] Referring to Figure 1 , Figure 2 and Figure 3In some embodiments, the base 100 further comprises two limiting side plates 130, which are arranged on the bottom plate 110 and are spaced apart along the second direction, such that the two guide side plates 120 are located between the two limiting side plates 130. The limiting side plates 130 and the guide side plates 120 are also spaced apart along the second direction. When the carrier 20 is fixed on the sliding unit 210, the carrier 20 can abut between the two limiting side plates 130, so that the two limiting side plates 130 limit the carrier 20 along the second direction. The limiting side plates 130 are slidably connected with the bottom plate 110 along the second direction. When the two limiting side plates 130 move towards each other along the second direction, the distance between the two limiting side plates 130 decreases. When the two limiting side plates 130 move away from each other along the second direction, the distance between the two limiting side plates 130 increases. Therefore, by moving the two limiting side plates 130, the distance between the two limiting side plates 130 can be reasonably adjusted, so that the two limiting side plates 130 can abut with carriers 20 of different sizes, thereby realizing the limiting of the two limiting side plates 130 to carriers 20 of different sizes along the second direction. The limiting side plates 130 can be bolted with the bottom plate 110. When it is necessary to adjust the distance between the two limiting side plates 130, the bolted connection between the limiting side plates 130 and the bottom plate 110 can be released. When the distance between the two limiting side plates 130 is adjusted, the limiting side plates 130 can be bolted with the bottom plate 110.
[0037] Referring to Figure 1 , Figure 2 and Figure 3 In some embodiments, the turnover unit 310 can be located in the spacing space 121 between the two guide side plates 120. The turnover mechanism 300 further comprises a second driver 320, which can be connected with the bottom plate 110. The bottom plate 110 is provided with an avoidance hole 111 which penetrates the bottom plate 110 along the thickness direction of the bottom plate 110, so that the avoidance hole 111 is a through hole. The second driver 320 is arranged in the avoidance hole 111 and connected with the turnover unit 310, so that the second driver 320 drives the turnover unit 310 to reciprocate along the third direction. So that the turnover unit 310 can enter or exit the spacing space 121 between the two guide side plates 120. Obviously, when the second driver 320 drives the turnover unit 310 to move upward along the third direction, the turnover unit 310 can be located outside the spacing space 121; when the second driver 320 drives the turnover unit 310 to move downward along the third direction, the turnover unit 310 can be located inside the spacing space 121. When the turnover unit 310 can be located outside the spacing space 121, the rotation of the carrier 20 carried on the turnover unit 310 can be avoided by the guide side plates 120, ensuring that the carrier 20 can rotate smoothly with the turnover unit 310. The second driver 320 can be a pneumatic cylinder.
[0038] Referring to Figure 1 , Figure 2 and Figure 3 , in some embodiments, the turnover unit 310 comprises a bearing plate 311, a third driver 312 and two abutting members 313. The bearing plate 311 is fixedly connected with the second driver 320, and the two abutting members 313 are arranged on the bearing plate 311. When the second driver 320 drives the bearing plate 311 to reciprocate up and down, the second driver 320 drives the entire turnover unit 310 to reciprocate up and down. The third driver 312 is arranged on the bearing plate 311, and the third driver 312 drives the two abutting members 313 to move towards or away from each other along the first direction, and the two abutting members 313 are used to clamp the carrier 20. For example, when the two abutting members 313 apply abutting force to the carrier 20 along the first direction, the carrier 20 can be fixed between the two abutting members 313, so as to realize the bearing and fixing of the turnover unit 310 to the carrier 20. It can be understood that when the two abutting members 313 move towards each other along the first direction, the distance between the two abutting members 313 decreases; when the two abutting members 313 move away from each other along the first direction, the distance between the two abutting members 313 increases. Therefore, by the movement of the two abutting members 313, the distance between the two abutting members 313 can be reasonably adjusted, so that the two abutting members 313 can abut against the carriers 20 of different sizes, so that the two abutting members 313 can clamp and fix the carriers 20 of different sizes.
[0039] The third driver 312 can be a pneumatic cylinder, the cylinder barrel of the pneumatic cylinder is fixed on the bearing plate 311, and the two telescopic rods of the pneumatic cylinder are respectively connected with the two abutting members 313. When the two telescopic rods of the pneumatic cylinder produce telescopic movement, the two abutting members 313 can move towards or away from each other along the first direction.
[0040] Referring to Figure 1 , Figure 2 and Figure 3In some embodiments, each abutting piece 313 comprises a supporting part 3131, an abutting part 3132 and a fourth driver 3133. The supporting part 3131 is connected with the third driver 312, the supporting part 3131 is slidingly arranged on the bearing plate 311, the abutting part 3132 is rotatably arranged on the supporting part 3131, and the abutting part 3132 is used to abut against the carrier 20 to realize the clamping action on the carrier 20. The fourth driver 3133 is arranged on the supporting part 3131, the fourth driver 3133 is connected with the abutting part 3132, and the fourth driver 3133 drives the abutting part 3132 to rotate around the rotation shaft 223 extending in the first direction. The fourth driver 3133 can be a rotary cylinder or a motor 221, etc. When the abutting part 3132 clamps the carrier 20, the fourth driver 3133 drives the abutting part 3132 to rotate, which will make the carrier 20 rotate along with the abutting part 3132, for example, the carrier 20 rotates 180° or 360° along with the abutting part 3132, etc.
[0041] Referring to Figure 1 , Figure 2 and Figure 3 , in operation, the third driver 312 can drive the two abutting pieces 313 to move, so that the carrier 20 is clamped between the two abutting parts 3132. Then the second driver 320 drives the bearing plate 311 to move upward, so that the carrier 20 is located outside the spacing space 121 between the two guide side plates 120. Then the fourth driver 3133 drives the abutting part 3132 to rotate, which will drive the carrier 20 to rotate outside the spacing space 121, so as to effectively avoid the interference of the guide side plate 120 to the rotation of the carrier 20. After the carrier 20 is rotated, the second driver 320 drives the bearing plate 311 to move downward, so that the carrier 20 is supported on the guide rail of the two guide side plates 120. For example, when the abutting piece 313 clamps the carrier 20, the carrier 20 is vertically arranged; after the carrier 20 is located outside the spacing space 121 and rotates 180° along with the abutting part 3132, the carrier 20 is horizontally arranged; then the second driver 320 drives the bearing plate 311 to move downward, so that the horizontally arranged carrier 20 is supported on the guide rail of the guide side plate 120. At this time, the first driver 220 drives the sliding unit 210 to move close to the carrier 20 to clamp the carrier 20, so as to realize the clamping of the horizontally arranged carrier 20 by the sliding unit 210.
[0042] The technical features of the above-mentioned embodiments can be combined in any manner. In order to make the description simple, not all possible combinations of the technical features in the above-mentioned embodiments are described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present disclosure.
[0043] The above embodiments only express several implementation ways of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation to the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application.
