However, the device has the following problems, first, the adsorption hole on the clamp body is only provided with one, only one single crystal diamond can be processed each time, and the operation efficiency is low;Second, if the adsorption hole opened on the suction surface is larger, the chips and impurities are easy to enter the adsorption hole when the clamp is in non-processing state, thereby causing blockage;Third, since the clamp involves inductive device and control device, the manufacturing cost is relatively high.

[0004] Therefore, the internal structure of diamond fixing device needs to be further improved. UTILITY MODEL CONTENTS

[0006] The second technical problem to be solved by the utility model is to provide a diamond fixing device capable of avoiding blockage of adsorption part in non-working state in view of the above existing technology, especially in the case of larger adsorption part.

[0007] The third technical problem to be solved by the utility model is to provide a relatively low-cost diamond fixing device.

[0008] The utility model solves the above-mentioned first technical problem adopts the technical scheme of: this diamond fixing device, including having:

[0009] The fixed base is equipped with the area of sticking together;

[0010] The suction unit is arranged in the fixed base and is used for adsorbing the diamond to be fixed in the set area of sticking together;

[0011] Its characterized in that: still including:

[0012] The separator is used for separating the area of sticking together into at least two sticking frames, and the peripheral part of each sticking frame can at least surround the local part of the diamond to be fixed.

[0013] The adsorption part is correspondingly arranged on the sticking frame and is used for placing the diamond to be fixed in the state of the corresponding sticking frame, and the diamond to be fixed is adsorbed by the suction unit.

[0014] Further, the suction unit includes the cavity arranged in the fixed base and the air extraction mechanism for extracting the cavity, and the fixed base is further provided with at least two first flow channel parts in communication with the adsorption part, each first flow channel part is in fluid communication with the adsorption part and the cavity, each first flow channel part constitutes the local part of the corresponding sticking frame, and the adsorption part is located between the cavity and the first flow channel part.

[0015] Further, the fixing seat is further provided with at least two second flow channel parts, each of the second flow channel parts is located downstream of the corresponding first flow channel part along the air flow direction, each of the second flow channel parts comprises an air inlet end, a third flow channel part is provided between the first flow channel part and the air inlet end, the cross-sectional area of the inlet end of the third flow channel part is smaller than that of the air outlet end of the first flow channel part, and the outlet end of the third flow channel part is the air inlet end. The cross-sectional area of the air outlet end of the first flow channel part is large, and the cross-sectional area of the inlet end of the third flow channel part is small compared with that of the air outlet end of the first flow channel part. When the diamond to be fixed closes the adsorption part, the air flow in the first flow channel part enters the narrow space of the third flow channel part from the spacious space, which generates a large extrusion force in a short time, the extrusion force is greater than the sealing force provided by the elastic member, the sealing member is forced to retreat towards the suction unit, thereby opening the air inlet end, the second flow channel part and the third flow channel part are both vacuumized, so that the diamond to be fixed is adsorbed on the adsorption part.

[0016] In order to solve the above-mentioned second technical problem, as a preferred, the second flow channel part is provided with a sealing member for opening and closing the air inlet end, and further comprises an elastic member for making the sealing member always have a trend of moving to the direction of the air inlet end to close the air inlet end. In the state that the diamond to be fixed is placed on the corresponding fitting frame, the air in the first flow channel part is extruded into the third flow channel part, so that the third flow channel part generates an extrusion force for forcing the sealing member to open the air inlet end. The air inlet end of the second flow channel part is in communication with the cavity. If the air inlet end is in an open state, the chips and impurities in the machining process will enter the cavity through the adsorption part, thereby causing blockage and affecting the adsorption of the diamond to be fixed. Through the cooperation of the sealing member and the elastic member, in the non-working state, the sealing member closes the air inlet end to avoid the entry of chips and impurities.

[0017] As aforementioned, when the diamond to be fixed is placed in the state of corresponding to the fitting frame, the third flow passage part generates the extrusion force to force the closing member to open the air inlet end, which necessarily adjusts the strength of the force of the elastic member acting on the closing member. Therefore, as a preferred embodiment, the fixing seat is provided with a mounting passage, and the mounting passage is provided with a control member for selectively providing the closing force of the elastic member. The control member is in a "T" shape and includes a first control section and a second control section connected with each other. The second control section extends along the moving direction of the closing member, and the first control section is used for regulating the closing force and exposed outside the mounting passage. The second control section is arranged in the mounting passage and can be mounted with the elastic member. When the diamond to be fixed is placed in the state of corresponding to the fitting frame, the extrusion force generated in the third flow passage part is greater than the preset reference closing force of the elastic member. The control member is arranged to continuously adjust the closing force provided by the elastic member in the early test stage. The control member in the application includes two parts, i.e., the first control section arranged outside the mounting passage and the second control section arranged in the mounting passage. The second control section can be mounted with the elastic member. The first control section can adjust the distance between the whole control member and the closing member by manual rotation, thereby adjusting the closing force provided by the elastic member and making the extrusion force generated in the third flow passage part greater than the closing force in a short time, so as to force the closing member to open the air inlet end.

[0018] In order to facilitate the installation of the elastic member, as a preferred embodiment, the second control section includes a first sub-control section and a second sub-control section. The second sub-control section is in a rod shape and has a smaller cross-sectional area than the first sub-control section. The elastic member is a compression spring sleeved on the second sub-control section. The compression spring has a fixed end and a free end. The fixed end is connected to the end face of the first sub-control section, and the free end always has a tendency to spring outwards of the closing member. The second sub-control section of the application is smaller in diameter than the first sub-control section. The main reason is that when the elastic member is sleeved on the second sub-control section, the fixed end can abut against the end face of the first sub-control section, and the free end can abut against the closing member. The structure is relatively simple to realize the installation of the compression spring, so as to better apply the outward spring force to the closing member.

[0019] In order to solve the third technical problem, as a preferred, the partition is locally outwardly convex along the bonding area, the partition is prismatic, the left and right side walls of the partition correspond to the frame bodies of the adjacent bonding frame respectively, and the partition and the first flow channel part jointly form a "U" shape with the opening upward, and the first flow channel part is located at the horizontal part of the "U" shape. Wherein, the partition divides the bonding area on the fixing seat into multiple sub-areas, each sub-area is a bonding frame formed by the partition and the first flow channel part, and the bonding frame has the advantages of the U shape: first, when the diamond to be fixed is placed on the bonding frame, the end face of the diamond to be fixed can be in contact with the bonding frame, thereby facilitating the fixing; second, when the diamond to be fixed is placed on the bonding frame from top to bottom, the air in the first flow channel part can be extruded into the third flow channel part, thereby making the third flow channel part generate the extrusion force to force the blocking piece to open the air inlet end.

[0020] In order to realize the vacuum environment, as a preferred, the fixing seat is provided with a mounting hole communicating with the cavity, the mounting hole is externally connected with the air extraction mechanism, the air extraction mechanism comprises a communication pipeline and a vacuum machine, one end of the communication pipeline is connected with the vacuum machine, and the other end is connected with the mounting hole.
