For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0033] Please refer to Figures 1 to 14 The jig rotating opening and closing mechanism provided for an embodiment of the present application is used for opening and closing the jig, and the jig comprises a support part 220 and a cover part 221 connected in rotation. In this embodiment, the cover mode of the support part 220 and the cover part 221 is snap connection (as shown in Figure 13 And Figure 14 The jig rotating opening and closing mechanism comprises an opening and closing assembly 10 and a horizontal assembly 20. In this embodiment, the jig is used for placing materials 40 (as shown in Figure 13 The materials 40 are chips. The horizontal assembly 20 comprises a horizontal driving mechanism 21 and a jig mounted on the horizontal driving mechanism 21. In this embodiment, the support part 220 is fixedly mounted on the horizontal driving mechanism 21. The opening and closing assembly 10 comprises an opening and closing bracket 11 mounted on the horizontal assembly 20, a vertical driving mechanism 12 and an opening and closing piece 13 (as shown in Figure 3 、 Figure 4 The opening and closing piece 13 is movably mounted on the opening and closing bracket 11 by the vertical driving mechanism 12. When it is necessary to close or open the jig, the horizontal driving mechanism 21 makes the jig translate to the opposite of the opening and closing piece 13, and the opening and closing piece 13 is cooperated with the vertical driving mechanism 12 and the horizontal driving mechanism 21 to make the support part 220 and the cover part 221 relatively close or open.

[0034] The working principle of the jig rotating opening and closing mechanism is as follows: in the initial state, the support part 220 and the cover part 221 of the jig are in the unclosed or open state; when the closing or opening operation is to be performed, the horizontal driving mechanism 21 is first operated; it drives the jig to move smoothly in the horizontal direction until the jig reaches the relative position of the opening and closing part 13; after the jig reaches the appropriate horizontal position, the vertical driving mechanism 12 is started. It controls the opening and closing part 13 to move in the vertical direction; if the jig needs to be closed, the horizontal driving mechanism 21 and the vertical driving mechanism 12 move simultaneously; the opening and closing part 13 moves downward, while the jig moves backward; the opening and closing part 13 pushes the cover part 221 to approach the support part 220, and finally realizes the close closing through the buckling connection. For example, like a precise mechanical arm, the horizontal driving mechanism 21 is responsible for "pushing" the jig to the designated position, and the vertical driving mechanism 12 commands the opening and closing part 13 to perform the "pressing" operation, and the two cooperate to make the cover part 221 and the support part 220 perfectly buckled; when the jig needs to be opened, only the vertical driving mechanism 12 makes the opening and closing part 13 move downward, pushing the cover part 221 away from the buckling part of the support part 220, thereby realizing the opening of the jig.

[0035] Compared with the prior art, the jig rotating opening and closing mechanism of the present application closely cooperates with the horizontal driving mechanism 21 and the vertical driving mechanism 12 during the whole process, accurately controls the movement of the jig and the action of the opening and closing part 13, thereby realizing the efficient and accurate opening and closing of the jig to meet the production or operation requirements; without manual operation, it is completely controlled by the mechanical driving mechanism, avoiding the unstable factors and errors that may be brought by manual operation; the automatic opening and closing operation saves the time of manual operation and speeds up the production process; the precise cooperation of the horizontal and vertical driving mechanisms 12 ensures the consistency of the opening and closing position and force of the jig each time.

[0036] Please refer to Figures 2 to 6The vertical driving structure 12 comprises a Z-axis moving mechanism and a Y-axis moving mechanism; the Z-axis moving mechanism comprises a Z-axis opening and closing slide rail 120 arranged on the opening and closing support 11, a Z-axis opening and closing support seat 121 slidably arranged on the Z-axis opening and closing slide rail 120, a Z-axis opening and closing motor 122 and an opening and closing bearing 123 arranged at two ends of the Z-axis opening and closing slide rail 120 respectively, a rotor of the Z-axis opening and closing motor 122 and the opening and closing bearing 123 are drivingly connected through a first opening and closing belt 124, and the Z-axis opening and closing support seat 121 is fixed on the first opening and closing belt 124; the Y-axis moving mechanism comprises a Y-axis opening and closing sliding seat 125 arranged on the Z-axis opening and closing support seat 121, a Y-axis opening and closing support seat 126 slidably arranged on the Y-axis opening and closing sliding seat 125, and the opening and closing piece 13 is arranged on the Y-axis opening and closing support seat 126; the Z-axis moving mechanism further comprises a linear motor 127, the linear motor 127 comprises a linear motor body and a screw rod, the linear motor body is fixedly arranged on the Z-axis support seat, and the screw rod is threadedly connected with the Y-axis opening and closing support seat 126. When the Z-axis opening and closing motor 122 is started, the rotor rotates to drive the opening and closing bearing 123 to rotate through the first opening and closing belt 124; since the Z-axis opening and closing support seat 121 is fixed on the first opening and closing belt 124, when the belt moves, the Z-axis opening and closing support seat 121 slides up and down along the Z-axis opening and closing slide rail 120, so that the position adjustment in the Z-axis direction is realized; when the linear motor 127 on the Z-axis opening and closing support seat 121 works, the motor body drives the screw rod to rotate; since the screw rod is threadedly connected with the Y-axis opening and closing support seat 126, the rotation of the screw rod is converted into the linear sliding of the Y-axis opening and closing support seat 126 in the Y-axis direction. Through the transmission of the linear motor 127 and the opening and closing belt 124 and the accurate driving of the screw rod, the high-precision position control in the Z-axis and Y-axis directions can be realized; the position of the opening and closing piece 13 in the vertical plane can be flexibly adjusted according to different working requirements; the stable slide rail and support seat structure and the reliable transmission mode make the whole driving process stable, and reduce the vibration and error.

[0037] The knob 221A is arranged on the cover 221. The opening and closing member 13 comprises a fixed part 130 and a screwing part 131, the fixed part 130 is sleeved on the screwing part 131 and is fixedly arranged on the Y-axis opening and closing support seat 126. The first tooth ring 132 is arranged on the Y-axis opening and closing support seat 126. The auxiliary bearing 133 is arranged between adjacent first tooth rings 132. The Y-axis opening and closing motor is arranged on the Y-axis opening and closing support seat 126. The rotor of the Y-axis opening and closing motor is sleeved with the second tooth ring 135. The first tooth ring 132 and the second tooth ring 135 are coaxially connected through the auxiliary bearing 133 and the second opening and closing belt 136. The free end of the screwing part 131 is arranged to cooperate with the knob 221A. When the cover needs to be closed, the horizontal driving mechanism 21 first moves the jig to the position opposite to the opening and closing member 13. The vertical driving mechanism 12 controls the opening and closing member 13 to move downward, so that the screwing part 131 is close to the knob 221A. Then, the Y-axis opening and closing motor is started. The second tooth ring 135 sleeved with the rotor of the Y-axis opening and closing motor drives the first tooth ring 132 to rotate through the auxiliary bearing 133 and the second opening and closing belt 136. Since the first tooth ring 132 is sleeved on the screwing part 131, the screwing part 131 starts to rotate. At the same time, the vertical driving mechanism 12 continues to control the opening and closing member 13 to move downward, so that the screwing part 131 is inserted into the knob 221A. With the continuous rotation of the screwing part 131 and the backward movement of the jig by the horizontal driving mechanism 21, the screwing part 131 interacts with the knob 221A to generate a rotating force, which promotes the cover 221 to be more tightly buckled with the support 220. For example, it is like a precise mechanical linkage system. The Y-axis opening and closing motor drives the screwing part 131 to rotate through the transmission of the tooth ring and the belt, like a smart screwdriver, which accurately tightens the cover 221. At the same time, since the connection between the material 40 and the cover 221 and the support 220 is more tight, the detection accuracy of the jig on the material is improved. When the jig needs to be opened, the vertical driving mechanism 12 controls the opening and closing member 13 to move downward, so that the screwing part 131 is in contact with the knob 221A again. The Y-axis opening and closing motor is reversed to drive the screwing part 131 to rotate in the opposite direction. The downward thrust of the opening and closing member 13 can overcome the buckling force between the screwing part 131 and the knob 221A, so as to push the cover 221 away from the support 220, thereby realizing the opening of the jig. Without manual operation one by one, the production efficiency is greatly improved. The motor-driven mode can ensure that the force and angle of each cover are consistent, so as to ensure that the tightness of the cover is the same, thereby improving the stability of product quality and the accuracy of detection results. The workers do not need to perform heavy manual cover operation, thereby reducing the labor intensity and reducing the decline of work efficiency and quality caused by fatigue.

[0038] A step 137 is outwardly extended on the screwing part 131, and a buffer 138 is arranged between the screwing part 131 and the fixing part 130, the buffer 138 is sleeved on the screwing part 131, one end of the buffer 138 abuts against the step 137, and the other end of the buffer 138 abuts against the fixing part 130; in the embodiment, the buffer 138 is a spring; the spring can transmit the rotating action of the screwing part 131 to the buffer 138; the buffer 138 is arranged outside the screwing part 131, one end of the buffer 138 abuts against the step 137 on the screwing part 131, and the other end of the buffer 138 abuts against the fixing part 130; in the process of rotating and screwing the screwing part 131, the buffer 138 is compressed by pressure; the spring can generate elastic force after the buffer 138 is compressed, and the elastic force can act on the screwing part 131 and the fixing part 130. The elastic force of the spring can increase the friction between the screwing part 131 and the fixing part 130, effectively prevent the screwing part 131 from loosening under the action of vibration or other external force, and ensure the reliability of the connection; when the system is impacted or vibrated, the spring can absorb and release energy, and reduce the damage to the connecting parts; even if there is a certain error in the manufacturing size of the screwing part 131 and the fixing part 130, or the assembly is not completely accurate, the elasticity of the spring can compensate for the deviation, and ensure the tightness of the connection.

[0039] Please refer to Figure 7 and Figure 8The horizontal driving mechanism 21 further comprises a horizontal base 210, a horizontal slide rail 211 arranged on the horizontal base 210, and a horizontal detection platform 212 slidably arranged on the horizontal slide rail 211; the horizontal base 210 is further provided with a horizontal conveying member, which has the same track direction as the horizontal slide rail 211; the horizontal conveying member comprises a first horizontal gear 214 mounted on the base and a horizontal driving motor 215, an outer ring of the first horizontal gear 214 is provided with external threads, a housing of the horizontal driving motor 215 is fixedly mounted on the horizontal base 210, a rotor of the horizontal driving motor 215 is provided with a third gear ring 216, the third gear ring 216 is drivingly connected with the first horizontal gear 214 through a horizontal conveying belt 217, and one end of the horizontal detection platform 212 is fixedly connected with the horizontal conveying belt 217. When the horizontal driving motor 215 is started, the rotor drives the third gear ring 216 to rotate; the third gear ring 216 transmits power to the first horizontal gear 214 through the horizontal conveying belt 217; the external threads arranged on the outer ring of the first horizontal gear 214 have the same rotating direction as the track direction of the horizontal slide rail 211, and when the first horizontal gear 214 rotates, the horizontal detection platform 212 fixedly connected with the horizontal conveying belt 217 is driven to move along the horizontal slide rail 211 through the transmission of the horizontal conveying belt 217. The accurate transmission and stable slide rail structure can realize high-precision position control of the horizontal detection platform 212 in the horizontal direction; the moving direction and distance of the horizontal detection platform 212 can be flexibly controlled according to the work requirement; the stable horizontal slide rail 211 and reliable transmission mode can keep the platform stable during movement, reduce vibration and error; the horizontal driving motor 215 can quickly respond to the control signal, rapidly realize position adjustment of the platform, and improve work efficiency.

[0040] The horizontal base 210 is also provided with a second gear 218 and a third gear 219. The second gear 218 is arranged in the same straight line as the first gear, and the third gear 219 is arranged between the second gear 218 and the third gear ring 216. The first gear, the second gear 218, and the third gear ring 216 are arranged in the horizontal transmission belt 217, and the third gear 219 is wound around the horizontal transmission belt 217 on one side of the first gear and the third gear ring 216. When the horizontal drive motor 215 is started, the rotor drives the third gear ring 216 to rotate. Since the third gear ring 216 is connected to the first gear through the horizontal transmission belt 217, the rotation of the third gear ring 216 drives the horizontal transmission belt 217 to move. The first gear, the second gear 218, and the third gear 219 wound around one side of the belt in the horizontal transmission belt 217 play a role in tensioning and guiding. The first gear and the second gear 218 are in the same straight line, which helps to maintain the stability and uniformity of the tension of the belt when it is driven in a straight line. The third gear 219 is wound around the horizontal transmission belt 217 on one side of the first gear and the third gear ring 216, which can further adjust the tension of the belt, prevent the belt from relaxing or jumping teeth during transmission, and ensure smooth and accurate power transmission.

[0041] The horizontal base 210 at both ends of the horizontal sliding rail 211 is also provided with a limiting block 220. When the horizontal detection platform 212 moves on the horizontal sliding rail 211, its movement range is limited by the length of the horizontal sliding rail 211. The limiting block 220 is arranged to block and limit the horizontal detection platform 212 when it approaches the two ends of the sliding rail. When the horizontal detection platform 212 moves towards one end and contacts the limiting block 220 at the end, the limiting block 220 will prevent the platform from continuing to move forward, thereby preventing the platform from moving excessively and causing damage to the equipment or work failure.

[0042] Please refer to Figures 9 to 12The fixture rotating opening and closing mechanism also includes a grabbing assembly 50, which includes a Z-axis grabbing slide rail arranged on the opening and closing bracket 11, an X-axis grabbing bracket 52 is slidably provided on the Z-axis grabbing slide rail, an X-axis grabbing bracket 52 is arranged on the X-axis grabbing slide rail, a Y-axis grabbing bracket 54 is slidably provided on the X-axis grabbing slide rail 53, an X-axis grabbing driving cylinder is arranged on the X-axis grabbing bracket 52, a Y-axis grabbing slide rail 55 is arranged on the Y-axis grabbing bracket 54, a Y-axis grabbing base 56 is slidably provided on the Y-axis grabbing base 56, a plurality of grabbing parts 57 are fixed on the Y-axis grabbing base 56, a Y-axis grabbing cylinder 58 is arranged on the Y-axis grabbing bracket 54, the cylinder barrel of the Y-axis grabbing cylinder 58 is fixed on the Y-axis grabbing bracket 54, and the piston rod of the Y-axis grabbing cylinder 58 is connected to the Y-axis grabbing base 56. First, the Z-axis grabbing slide controls the movement of the X-axis grabbing bracket 52 in the Z-axis direction, so that it can rise or fall to an appropriate height position; then, the X-axis grabbing slide 53 drives the Y-axis grabbing bracket 54 to move horizontally in the X-axis direction, adjusting the left and right position of the grabbing member 57 on the horizontal plane; then, the Y-axis grabbing slide 55 enables the Y-axis grabbing base 56 to slide in the Y-axis direction, further fine-tuning the front and rear position of the grabbing member 57 on the horizontal plane; when a grabbing operation is required, the Y-axis grabbing cylinder 58 is driven; the piston rod of the Y-axis grabbing cylinder 58 is extended and retracted, pushing or pulling the Y-axis grabbing base 56 connected to it to move along the Y-axis grabbing slide 55, thereby driving the grabbing member 57 fixed on the Y-axis grabbing base 56 to approach or move away from the object to be grabbed, realizing the grabbing and releasing actions. Through the cooperation of the Z-axis, X-axis, and Y-axis slide rails and the Y-axis grasping cylinder 58, precise position adjustment with multiple degrees of freedom can be achieved in three-dimensional space, thereby accurately grasping objects of various shapes and positions; rapid movement and accurate positioning in all directions can reduce the time required for grasping and improve the overall efficiency of the production process; high-precision and automated grasping operations reduce dependence on manual operations, reduce labor costs, and improve work consistency and quality.

[0043] The grabbing member 57 comprises a grabbing motor 570 mounted on the Y-axis grabbing bracket 54 and a grabbing part 571 penetrating the grabbing bracket in the same direction as the Y-axis grabbing slide rail 55. The shell of the grabbing motor 570 is fixedly mounted on the Y-axis grabbing bracket 54, and the rotor of the grabbing motor 570 is in transmission connection with the grabbing part 571 through a grabbing belt 572. When the grabbing operation is needed, the grabbing motor 570 is started. The rotor of the grabbing motor 570 rotates, and the power is transmitted to the grabbing part 571 through the belt. Since the grabbing part 571 penetrates the Y-axis grabbing bracket 54 in the same direction as the Y-axis grabbing slide rail 55, when the belt drives the grabbing part 571 to move, the grabbing part 571 will perform the actions of stretching or rotating in the penetrating direction, so as to realize the grabbing or releasing of the object. Through the transmission of the motor and the belt, the accurate control of the action of the grabbing part 571 can be realized, so as to ensure the accuracy and stability of the grabbing. According to the different designs of the grabbing part 571, various grabbing actions such as stretching and rotating can be realized, so as to adjust the grabbing angle of the grabbing member 57 according to the position and shape of the material 40.

[0044] The grabbing part 571 comprises a first grabbing end 571A and a second grabbing end 571B. The first grabbing end 571A is in transmission connection with the rotor of the grabbing motor 570, and the second grabbing end 571B is sleeved outside the first grabbing end 571A. An elastic member 571C for buffering is arranged between the second grabbing end 571B. In the embodiment, the elastic member 571C is a spring. When the grabbing motor 570 is started, the rotation of the rotor drives the first grabbing end 571A to move through the transmission mechanism. The first grabbing end 571A is the part of the active movement, and its action is directly controlled by the grabbing motor 570. The second grabbing end 571B is sleeved outside the first grabbing end 571A, and when the first grabbing end 571A moves, the second grabbing end 571B is pushed or pulled. The elastic member 571C between the first grabbing end 571A and the second grabbing end 571B can provide buffering when grabbing and releasing the object, effectively reducing the damage of the impact force to the grabbed object. In the face of the object with irregular shape or uneven surface, the stretching and contraction of the elastic member 571C can make the second grabbing end 571B better fit the surface of the object, and improve the stability and reliability of the grabbing.
