[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0032] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] See also Figures 1 to 14 , a fixture rotating opening and closing mechanism provided in an embodiment of the present invention, is used to open and close the fixture, and the fixture includes a support portion 220 and a covering portion 221 that are rotatably connected; in this embodiment, the covering method of the support portion 220 and the covering portion 221 is a buckle connection (such as Fig.13 and Fig.14 As shown). The fixture rotary opening and closing mechanism includes an opening and closing component 10 and a horizontal component 20; in this embodiment, the fixture is used to place a material 40 (such as Fig.13 ); the material 40 is a chip. The horizontal component 20 includes a horizontal driving mechanism 21 and a fixture installed on the horizontal driving mechanism 21; in this embodiment, the support part 220 is fixedly installed on the horizontal driving mechanism 21. The opening and closing component 10 includes an opening and closing bracket 11 installed on the horizontal component 20, a vertical driving mechanism 12 and an opening and closing member 13 (as shown in FIG. Figure 3 , Figure 4 As shown in the figure, the opening and closing member 13 is movably mounted on the opening and closing bracket 11 through the vertical driving mechanism 12; when the fixture needs to be closed or opened, the horizontal driving mechanism 21 makes the fixture move horizontally to the opposite side of the opening and closing member 13, and the opening and closing member 13 cooperates with the vertical driving mechanism 12 and the horizontal driving mechanism 21 to make the support part 220 and the covering part 221 relatively closed or opened.

[0034] The working principle of the jig rotating opening and closing mechanism involved in the present invention is as follows: in the initial state, the support part 220 and the covering part 221 of the jig are in an uncovered or open state; when the covering or opening operation is to be performed, the horizontal drive mechanism 21 is operated first; it drives the jig to move smoothly in the horizontal direction until the jig reaches the relative position of the opening and closing member 13; after the jig reaches the appropriate horizontal position, the vertical drive mechanism 12 is started. It controls the opening and closing piece 13 to move in the vertical direction; if the jig needs to be covered, the horizontal drive mechanism 21 and the vertical drive mechanism 12 move simultaneously; the opening and closing piece 13 moves downward, and the jig moves backward at the same time; the opening and closing piece 13 pushes the covering part 221 to approach the support part 220, and finally achieves tight covering through snap connection; for example, like a precise mechanical arm, the horizontal drive mechanism 21 is responsible for "pushing" the jig to the specified position, while the vertical drive mechanism 12 directs the opening and closing piece 13 to perform a "pressing" operation, and the two work together to make the covering part 221 and the support part 220 perfectly snap together; when the jig needs to be opened, only the vertical drive mechanism 12 moves the opening and closing piece 13 downward, pushing the covering part 221 away from the snap connection of the support part 220, thereby achieving the opening of the jig.

[0035] Compared with the prior art, the jig rotating opening and closing mechanism involved in the present invention, during the whole process, closely cooperates with the horizontal drive mechanism 21 and the vertical drive mechanism 12 to accurately control the movement of the jig and the action of the opening and closing member 13, thereby realizing efficient and accurate opening and closing of the jig to meet the requirements of production or operation; no manual operation is required, and it is completely controlled by the mechanical drive mechanism, avoiding the unstable factors and errors that may be caused by manual operation; the automated opening and closing operation saves the time of manual operation and speeds up the production process; the precise cooperation of the horizontal and vertical drive mechanisms 12 ensures that the opening and closing position and force of the jig are consistent each time.

[0036] See also Figures 2 to 6The vertical driving structure 12 includes a Z-axis movable mechanism and a Y-axis movable mechanism; the Z-axis movable mechanism includes a Z-axis opening and closing slide rail 120 arranged on the opening and closing bracket 11, a Z-axis opening and closing support seat 121 is slidably provided 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 are respectively arranged at both ends of the Z-axis opening and closing slide rail 120, the rotor of the Z-axis opening and closing motor 122 and the opening and closing bearing 123 are connected by a first opening and closing belt 124, and the Z-axis opening and closing support seat 121 is fixed to the first opening and closing belt 124. The Y-axis movable mechanism includes a Y-axis opening and closing sliding seat 125 arranged on the Z-axis opening and closing support seat 121, and a Y-axis opening and closing support seat 126 is slidably provided on the Y-axis opening and closing sliding seat 125, and the opening and closing member 13 is installed on the Y-axis opening and closing support seat 126; the Z-axis movable mechanism also includes a linear motor 127, the linear motor 127 includes a linear motor 127 body and a screw rod, the linear motor 127 body is fixedly installed on the Z-axis support seat, and the screw rod is threadedly connected to the Y-axis opening and closing support seat 126. When the Z-axis opening and closing motor 122 is started, its rotor rotates, and the opening and closing bearing 123 is driven 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, thereby realizing the position adjustment in the Z-axis direction; when the linear motor 127 on the Z-axis opening and closing support seat 121 is working, the motor body drives the screw to rotate; since the screw is threadedly connected to the Y-axis opening and closing support seat 126, the rotation of the screw will be 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, as well as the precise drive of the screw, high-precision position control can be achieved in the Z-axis and Y-axis directions; the position of the opening and closing member 13 in the vertical plane can be flexibly adjusted according to different work requirements; the stable slide rail and support seat structure, as well as the reliable transmission method, make the entire driving process smooth and reduce vibration and error.

[0037] A knob 221A is provided on the covering portion 221, and the opening and closing member 13 includes a fixing portion 130 and a tightening portion 131 which are installed on the Y-axis opening and closing support seat 126, the fixing portion 130 is sleeved on the outside of the tightening portion 131, and is fixedly installed on the Y-axis opening and closing support seat 126; a first gear ring 132 is sleeved on one end of the tightening portion 131 close to the Y-axis opening and closing support seat 126, the first gear ring 132 is arranged in the Y-axis opening and closing support seat 126, and an auxiliary bearing 133 is arranged between adjacent first gear rings 132; a Y-axis opening and closing motor is also provided on the Y-axis opening and closing support seat 126, and a second gear ring 135 is provided on the rotor outer sleeve of the Y-axis opening and closing motor, the first gear ring 132 and the second gear ring 135 are coaxially connected through the auxiliary bearing 133 and the second opening and closing belt 136, and the free end of the tightening portion 131 is arranged to cooperate with the knob 221A. When the fixture needs to be closed, the horizontal drive mechanism 21 first moves the fixture to a position relative to the opening and closing member 13, and the vertical drive mechanism 12 controls the opening and closing member 13 to move downward, so that the tightening portion 131 is close to the knob 221A; then, the Y-axis opening and closing motor is started, and the second gear ring 135 arranged on the outer outer surface of the rotor drives the first gear ring 132 to rotate through the auxiliary bearing 133 and the second opening and closing belt 136; since the first gear ring 132 is arranged on the tightening portion 131, the tightening portion 131 starts to rotate; while the tightening portion 131 rotates, the vertical drive mechanism 12 continues to control the opening and closing member 13 to move downward, so that the tightening portion 131 is close to the knob 221A; then, the Y-axis opening and closing motor is started, and the second gear ring 135 arranged on the outer surface of the rotor drives the first gear ring 132 to rotate through the auxiliary bearing 133 and the second opening and closing belt 136; since the first gear ring 132 is arranged on the tightening portion 131, the tightening portion 131 starts to rotate; while the tightening portion 131 rotates, the vertical drive mechanism 12 continues to control the opening and closing member 13 to move downward, so that the tightening portion 131 is close to the knob 221A; The part 131 is inserted into the knob 221A; as the tightening part 131 continues to rotate and the horizontal driving mechanism 21 moves the fixture backward, the tightening part 131 interacts with the knob 221A to generate a rotational force, which causes the covering part 221 to be more tightly buckled with the supporting part 220; for example, this is like a precise mechanical linkage system, and the Y-axis opening and closing motor drives the tightening part 131 to rotate through the transmission of the gear ring and the belt, just like an intelligent screwdriver, which accurately tightens the covering part 221; at the same time, because the material 40 is more closely connected with the covering part 221 and the supporting part 220, the detection accuracy of the fixture for the material is improved. When the fixture needs to be opened, the vertical drive mechanism 12 controls the opening and closing member 13 to move downward, so that the tightening part 131 contacts the knob 221A again; the Y-axis opening and closing motor reverses, driving the tightening part 131 to rotate in the opposite direction; the downward thrust of the opening and closing member 13 overcomes the locking force between the tightening part 131 and the knob 221A, and pushes the closing part 221 away from the support part 220, thereby opening the fixture; there is no need for manual operation one by one, which greatly improves production efficiency; the motor-driven method can ensure that the force and angle of each closing are consistent, thereby ensuring the same degree of tightness of the closing, improving the stability of product quality and the accuracy of test results; workers do not need to perform heavy manual closing operations, which reduces labor intensity and reduces work efficiency and quality decline due to fatigue.

[0038] A step 137 extends outward from the tightening portion 131, and a buffer 138 is arranged between the fixing portion 130 and the tightening portion 131. The buffer 138 is sleeved outside the tightening portion 131, with one end abutting against the step 137 and the other end abutting against the fixing portion 130. In this embodiment, the buffer 138 is a spring. The existence of the spring enables the rotation of the tightening portion 131 to be transmitted to the buffer 138. The buffer 138 is arranged outside the tightening portion 131, with one end abutting against the step 137 on the tightening portion 131 and the other end abutting against the fixing portion 130. During the process of rotating and tightening the tightening portion 131, pressure is applied to the buffer 138, causing the buffer 138 to be compressed. After the buffer 138 is compressed, an elastic force is generated, and this elastic force reacts to the tightening portion 131 and the fixing portion 130. The elastic force of the spring can increase the friction between the tightening part 131 and the fixing part 130, effectively preventing the tightening part 131 from loosening under vibration or other external forces, thereby ensuring the reliability of the connection; when the system is subjected to impact or vibration, the expansion and contraction of the spring can absorb and release energy, thereby reducing damage to the connecting parts; even if there are certain errors in the manufacturing dimensions of the tightening part 131 and the fixing part 130, or if the assembly is not completely accurate, the elasticity of the spring can compensate for these deviations and ensure the tightness of the connection.

When the horizontal drive motor 215 is started, its rotor drives the third gear ring 216 of the outer casing to rotate; the third gear ring 216 transmits power to the first horizontal gear 214 through the horizontal transmission belt 217; the outer thread set by the outer ring of the first horizontal gear 214, and its rotation direction is the same as the track direction of the horizontal slide rail 211, when the first horizontal gear 214 rotates, through the transmission of the horizontal transmission belt 217, it will drive the horizontal detection platform 212 fixedly connected to the horizontal transmission belt 217 to move along the horizontal slide rail 211. The precise 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 work needs; the stable horizontal slide rail 211 and the reliable transmission method keep the platform stable during the movement process, reduce vibration and error; the horizontal drive motor 215 can quickly respond to the control signal, quickly realize the position adjustment of the platform, and improve work efficiency.

When the horizontal drive motor 215 is started, its 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 will drive the horizontal transmission belt 217 to move; the first gear, the second gear 218 and the third gear 219 wrapped around one side of the belt arranged in the horizontal transmission belt 217 play a role of 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 during linear transmission; the third gear 219 is wrapped 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 to prevent the belt from loosening or jumping teeth during transmission, thereby ensuring smooth and accurate power transmission.

[0041] Limit blocks 220 are also provided on the horizontal base 210 at both ends of the horizontal slide rail 211. When the horizontal detection platform 212 moves on the horizontal slide rail 211, its range of motion is limited by the length of the horizontal slide rail 211; and the limit blocks 220 are provided to block and limit the horizontal detection platform 212 when it approaches both ends of the slide rail; when the horizontal detection platform 212 moves toward one end and contacts the limit block 220 at that end, the limit block 220 will stop the platform from moving forward, thereby preventing the platform from leaving the slide rail due to excessive movement, causing equipment damage or work errors.

[0042] See also 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 53, 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 members 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 rail controls the movement of the X-axis grabbing bracket 52 in the Z-axis direction, so that it can rise or fall to a suitable height position; then, the X-axis grabbing rail 53 drives the Y-axis grabbing bracket 54 to move horizontally in the X-axis direction, and adjusts the left and right position of the grabbing member 57 on the horizontal plane; then, the Y-axis grabbing rail 55 enables the Y-axis grabbing base 56 to slide in the Y-axis direction, and further fine-tune the front and rear position of the grabbing member 57 on the horizontal plane; when the 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 thereto to move along the Y-axis grabbing rail 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, thereby realizing the grabbing and releasing actions.

The grabbing part 571 penetrates the grabbing bracket in the same direction as the Y-axis grabbing slide rail 55. The housing of the grabbing motor 570 is fixedly installed on the Y-axis grabbing bracket 54. The rotor of the grabbing motor 570 is connected to the grabbing part 571 through a grabbing belt 572. When the grabbing operation is required, 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, and its penetration direction is the same as the Y-axis grabbing slide rail 55, when the belt drives the grabbing part 571 to move, the grabbing part 571 will perform actions such as extension or rotation along its penetration direction, thereby achieving the grasping or release of the object. Through the transmission of the motor and the belt, the movement of the grabbing part 571 can be precisely controlled to ensure the accuracy and stability of the grabbing; according to the different designs of the grabbing part 571, various grabbing actions such as telescopic and rotation 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 portion 571 includes a first grabbing end 571A and a second grabbing end 571B. The first grabbing end 571A is drivingly connected to 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 this embodiment, the elastic member 571C is a spring. When the grabbing motor 570 is started, the rotation of its rotor drives the first grabbing end 571A to move through the transmission mechanism; the first grabbing end 571A is the active moving part, and its movement 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, it pushes or pulls the second grabbing end 571B; the elastic member 571C between the second grabbing end 571B and the first grabbing end 571A can provide buffering when grabbing and releasing objects, effectively reducing the damage to the grasped objects caused by the impact force; in the face of objects with irregular shapes or uneven surfaces, the expansion and contraction of the elastic member 571C can make the second grabbing end 571B better fit the surface of the object, thereby improving the stability and reliability of the grabbing.

[0045] The above only expresses the preferred technical solution of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, and the present invention is also intended to include these modifications and modifications.
