[0011] Preferably, the marking method of the marking device for testing a sample comprises the following steps:

[0012] S1: First, the workpieces are placed one by one on a receiving seat by a manipulator, and after placement, the drive motor is controlled to drive the transmission shaft to rotate, and the transmission belt is used to drive the drive shaft to rotate synchronously, so that the drive disk rotates, and during the rotation, the two triangular disks are intermittently driven to rotate by the driving column, so that the drive shaft can intermittently rotate 120 degrees, and the circular seat is driven to rotate synchronously during the rotation of the drive shaft. Through the cooperation of the set linkage roller and the transmission gear, under the action of the transmission roller, the cross is synchronously rotated on the outside of the drive shaft, so that each receiving seat can be driven to move toward the direction of the marking machine one by one through the cooperation of the arc block and the annular groove, and during the movement, the receiving seat does not rotate, and the control shaft rotates in the receiving seat, so that each workpiece approaches the output end of the marking machine one by one and performs marking work;

[0013] S2: When the workpieces are placed one by one on a receiving seat by the manipulator, the downward force of the manipulator can squeeze the top of the fixed sleeve, and drive the fixed sleeve to drive the moving block to move downward synchronously through the connecting block, and compress the telescopic spring during the downward movement, and through the cooperation of the first hinge rod and the second hinge rod, the sliding shaft is synchronously slid on the sliding frame, driving a plurality of inner support members to move away from each other, and abut against the inner wall of the workpiece through the set flexible spring block. When the bottom of the workpiece contacts the receiving seat, the plurality of inner support members fix the position of the workpiece through the flexible spring block, and when the moving block moves downward, the locking plate is driven to move downward synchronously through the locking rod, and under the action of the curved slide groove and the matching rod, the position of the locking rod after moving downward is locked, and then the unfolded positions of the plurality of inner support members are synchronously locked.

[0014] S3: In the process of the receiving seat moving toward the marking machine, the control shaft drives several inner support parts to rotate synchronously, thereby driving the workpiece to rotate synchronously. When the working raised surface of the workpiece rotates to the limit opening, the working raised surface and the abutment cooperate with each other, thereby driving several first spring telescopic rods to contract one by one. When the working raised surface is about to coincide with the limit opening, the first spring telescopic rod located at the outermost side in the rotation direction contracts, and drives the trigger block to move synchronously, thereby driving the L-shaped connecting rod to move synchronously, and pushes the auxiliary wedge block through the abutment rod to move the control column, and synchronously causes the second spring telescopic rod to contract. When the auxiliary wedge block abuts on the abutment wedge frame, the auxiliary wedge block The control column contracts toward the inside of the control column. At this time, the auxiliary wedge block is out of contact with the abutting rod. Under the action of the second spring telescopic rod, the control column moves in the direction of the control axis, and makes the unlocking wedge block abut against the control wedge block, so that the control wedge block drives the locking plate to move down again, and then makes the matching rod move to the bottom along the curved slide groove. At this time, the fixed sleeve is reset under the action of the telescopic spring, and then under the action of the first hinged rod and the second hinged rod, several inner support parts gather together and break away from the contact with the inner wall of the workpiece, so that the workpiece is unlocked and the working protruding surface is stuck in the limiting mouth. When the workpiece stays at the side end of the marking machine, the working protruding surface of the workpiece can face the marking machine.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the present invention, when the device is used, the staff first places the workpieces one by one in a carrying device through a manipulator, and in the process of placing, fixes the workpieces from the inside of the tubular workpiece through a set fixing component, and after the fixing is completed, the fixing component is self-locked through a set locking component, and then under the action of the driving component, the feeding component drives a plurality of receiving devices to approach the output end of the marking machine one by one, avoiding the need for the staff to manually move the positions of the workpieces one by one, simplifying the working steps, thereby improving the marking efficiency, and in the process of moving, driving each receiving device to rotate, so as to facilitate the workpiece to rotate through the fixing component, when the surface of the workpiece is When the raised part of the mark is facing the marking machine, the control component is driven to work through the set trigger component, thereby unlocking the locking component and simultaneously releasing the fixation of the workpiece by the fixing component, so that the workpiece is separated from the contact with the fixing component, so that when the workpiece stays at the side end of the marking machine, the raised working surface of the workpiece can face the marking machine, thereby avoiding the need for the staff to manually move the designated area of ​​the workpiece to be marked toward the output end of the marking machine, thereby facilitating the operation of the marking machine and further improving the practicality of the device, thereby achieving the ability to automatically drive the workpiece to move to the working area while adjusting the working raised surface of the workpiece, so as to avoid the effects of low marking efficiency and insufficient practicality.

[0017] In the present invention, firstly, the workpieces are placed on a receiving seat one by one by a manipulator, and after placement, the drive motor is controlled to drive the transmission shaft to rotate, and the drive belt is used to drive the drive shaft to rotate synchronously, so that the drive disk rotates, and in the process of rotation, the two triangular disks are intermittently driven to rotate by the drive column, so that the drive shaft can intermittently rotate 120 degrees, and the circular seat is driven to rotate synchronously during the rotation of the drive shaft, and the cross is synchronously rotated on the outside of the drive shaft by the cooperation of the provided linkage roller and the transmission gear under the action of the transmission roller, so that each receiving seat can be driven to move toward the direction of the marking machine one by one through the cooperation of the arc block and the annular groove, and in the process of movement, the receiving seat does not rotate and the control shaft rotates in the receiving seat, so that each workpiece approaches the output end of the marking machine one by one and performs marking work, avoiding the need for staff to manually move the workpiece position one by one, simplifying the working steps, and thus improving the marking efficiency.

[0018] When the workpiece is placed on a receiving seat one by one by a manipulator, the downward force of the manipulator can be used to squeeze the top of the fixed sleeve and drive the fixed sleeve to drive the moving block to move downward synchronously through the connecting block, and compress the telescopic spring during the downward movement. Through the cooperation of the first hinge rod and the second hinge rod, the sliding shaft is synchronously slid on the sliding frame, driving a plurality of inner support members to move away from each other, and abut against the inner wall of the workpiece through the set flexible spring block. When the bottom of the workpiece contacts the receiving seat, the plurality of inner support members fix the position of the workpiece through the flexible spring block, and when the moving block moves downward, the locking plate is driven to move downward synchronously through the locking rod. Under the action of the curved slide groove and the matching rod, the position of the locking rod after moving downward is locked, and then the unfolded positions of the plurality of inner support members are synchronously locked, thereby completing the connection between the workpiece and the inner support member, facilitating the adjustment of the working raised surface of the workpiece, and improving the convenience of using the device.

[0019] In the present invention, during the process of the receiving seat moving toward the marking machine, the control shaft drives the plurality of inner support members to rotate synchronously, thereby driving the workpiece to rotate synchronously. When the working protruding surface of the workpiece rotates to the limiting opening, the working protruding surface cooperates with the abutting member, thereby driving the plurality of first spring telescopic rods to contract one by one. When the working protruding surface is about to coincide with the limiting opening, the first spring telescopic rod located at the outermost side in the rotation direction contracts, and drives the trigger block to move synchronously, thereby driving the L-shaped connecting rod to move synchronously, and pushes the auxiliary wedge block through the abutting rod to move the control column, thereby causing the second spring telescopic rod to contract synchronously. When the auxiliary wedge block abuts against the abutting wedge frame, the auxiliary wedge block contracts toward the inside of the control column. At this time, the auxiliary wedge block is out of contact with the abutting rod, and the second spring telescopic rod is retracted. Under the action of the spring telescopic rod, the control column moves in the direction of the control axis, and makes the unlocking wedge block contact with the control wedge block, so that the control wedge block drives the locking plate to move down again, and then makes the matching rod move to the bottom along the curved slide groove. At this time, the fixed sleeve is reset under the action of the telescopic spring, and then under the action of the first hinge rod and the second hinge rod, a plurality of inner support members gather together and break away from the contact with the inner wall of the workpiece, so that the workpiece is unlocked and the working protruding surface is stuck in the restriction mouth, so that when the workpiece stays at the side end of the marking machine, the working protruding surface of the workpiece can face the marking machine, thereby avoiding the need for the staff to manually turn the designated area of ​​the workpiece to be marked toward the output end of the marking machine, thereby facilitating the operation of the marking machine and further improving the practicality of the device.

[0042] The use method and advantages of the present invention: The marking method of the marking device for testing samples has the following working process:

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 and Fig.13 As shown:

[0044] S1: First, the workpieces are placed one by one on a receiving seat 69 by the manipulator 4. After placement, the drive motor 54 is controlled to drive the transmission shaft 55 to rotate, and the transmission belt 56 is used to drive the drive shaft 57 to rotate synchronously, so that the drive disk 51 rotates, and in the process of rotation, the two triangular disks 58 are intermittently driven to rotate by the driving column 53, so that the drive shaft 57 can intermittently rotate 120 degrees, and in the process of the rotation of the drive shaft 57, the circular seat 64 is driven to rotate synchronously, and through the cooperation of the provided linkage roller 65 and the transmission gear 68, under the action of the transmission roller 63, the cross 66 is synchronously rotated on the outside of the drive shaft 57, so that each receiving seat 69 can be driven to move one by one in the direction of the marking machine 2 through the cooperation of the arc block 70 and the annular groove 71, and in the process of movement, the receiving seat 69 does not rotate, and the control shaft 67 rotates in the receiving seat 69, so that each workpiece approaches the output end of the marking machine 2 one by one and performs marking work;

[0045] S2: When the workpieces are placed one by one on a receiving seat 69 by the manipulator 4, the downward force of the manipulator 4 can squeeze the top of the fixed sleeve 811, and drive the fixed sleeve 811 to drive the moving block 813 to move downward synchronously through the connecting block 814, and compress the telescopic spring 824 during the downward movement. Through the cooperation of the first hinge rod 816 and the second hinge rod 822, the sliding shaft 817 is synchronously slid on the sliding frame 819, driving the plurality of inner support members 818 to move away from each other, and abut against the inner wall of the workpiece through the set flexible spring block 820. When the bottom of the workpiece contacts the receiving seat 69, the plurality of inner support members 818 fix the position of the workpiece through the flexible spring block 820, and when the moving block 813 moves downward, the locking plate 832 is driven to move downward synchronously through the locking rod 831. Under the action of the curved slide groove 833 and the matching rod 835, the position of the locking rod 831 after moving downward is locked, and then the unfolded position of the plurality of inner support members 818 is synchronously locked.

[0046] S3: In the process of the receiving seat 69 moving toward the marking machine 2, the control shaft 67 drives the plurality of inner support members 818 to rotate synchronously, thereby driving the workpiece to rotate synchronously. When the working raised surface of the workpiece rotates to the limiting opening 92, the working raised surface cooperates with the abutment member 94, thereby driving the plurality of first spring telescopic rods 93 to contract one by one. When the working raised surface is about to coincide with the limiting opening 92, the first spring telescopic rod 93 located at the outermost side in the rotation direction contracts and drives the trigger block 95 to move synchronously, thereby driving the L-shaped connecting rod 101 to move synchronously, and pushing the auxiliary wedge block 105 through the abutment rod 106 to move the control column 104, thereby causing the second spring telescopic rod 103 to contract synchronously. When the auxiliary wedge block 105 abuts against the abutment wedge frame 107, the auxiliary wedge block 105 moves toward the control column 1 04 contracts on the inside, at this time the auxiliary wedge block 105 is out of contact with the abutment rod 106, under the action of the second spring telescopic rod 103, the control column 104 moves in the direction of the control shaft 67, and makes the unlocking wedge block 108 abut against the control wedge block 836, so that the control wedge block 836 drives the locking plate 832 to move down again, and then makes the matching rod 835 move to the bottom along the curved slide groove 833, at this time the fixed sleeve 811 is reset under the action of the telescopic spring 824, and then under the action of the first hinged rod 816 and the second hinged rod 822, the several inner support members 818 gather together and break away from the contact with the inner wall of the workpiece, so that the workpiece is unlocked and the working protrusion surface is stuck in the limiting opening 92, so that when the workpiece stays at the side end of the marking machine 2, the working protrusion surface of the workpiece can face the marking machine 2.
