[0055] like Figure 1-Figure 5 As shown, in the first embodiment of the slide chamber transfer device of the present invention, the slide chamber transfer device 10 includes at least a linear guide rail assembly 100, a sample feeding vehicle 120, a storage mechanism 130, a limiting mechanism 140, a pressing mechanism 150 and a sample feeding mechanism 200.

[0056] The linear guide assembly 100 is fixed on one side of the working platform 10 a and is used to control the reciprocating movement of the sample feeding vehicle 120 and the storage mechanism 130 .

[0057] The sample introduction vehicle 120 is fixed on the working platform 10 a , and the top thereof is configured as an open square structure, which is used to store the target object 121 to be extracted.

[0058] The storage mechanism 130 is fixed on the working platform 10 a and has a rectangular parallelepiped structure. An open square groove 130 a is formed at its upper end for temporarily storing the target object 121 clamped from the sample feeding vehicle 120 by the sample feeding mechanism 200 .

[0059] The limiting mechanism 140 is disposed on one side of the square groove 130 a , and at least a portion thereof extends into the square groove 130 a .

[0060] The pressing mechanism 150 is disposed on the other side of the square groove 130 a and is disposed opposite to the limiting mechanism 140 , forming a placement cavity 130 c for placing the target object 121 therebetween.

[0061] The sample introduction mechanism 200 is disposed on adjacent sides of the storage mechanism 130 and the sample introduction vehicle 120 , and is used to clamp the target object 121 in the sample introduction vehicle 120 , and rotate the clamped target object 121 to be placed into the placement cavity 130 c .

[0062] Specifically, the storage mechanism 130 is used to temporarily store the target object 121 .

[0063] The limiting mechanism 140 is disposed at one end of the storage mechanism 130 , and at least a portion thereof extends through the outer edge of the storage mechanism 130 into the interior thereof to form a limiting clamp on the first side (or front side).

[0064] The components extending from the limiting mechanism 140 to the storage mechanism 130 are relatively movable.

[0065] The pressing mechanism 150 is disposed at the other end of the storage mechanism 130 and is arranged opposite to the limiting mechanism 140 to form a limiting clamp on the second side (or rear side).

[0066] The pressing mechanism 150 and the limiting mechanism 140 extend into the storage mechanism 130 to form a placement cavity 130 c for placing the target object 121 .

[0067] like Figure 9 As shown, a transmission mechanism 300 is provided at the bottom of the storage mechanism 130 , and the transmission mechanism 300 is connected to the pressing mechanism 150 to control the pressing mechanism 150 to reciprocate along the axial direction of the square slot 130 a.

[0068] Furthermore, the sample feeding mechanism 200 is disposed on an adjacent side of the storage mechanism 130 , and is used to grab the target object 121 placed in the sample feeding vehicle 120 , and then transfer the target object 121 to the placement cavity 130 c of the storage mechanism 130 .

[0069] When the target object 121 is placed into the placement cavity 130c by the injection mechanism 200, the limiting mechanism 140 limits and fixes one end of the target object 121, and the pressing mechanism 150 is controlled by the transmission mechanism 300 to move along one side of the limiting mechanism 140, thereby limiting the axial space of the placement cavity 130c, so that the pressing mechanism 150 presses the other end of the target object 121.

[0070] When the pressing mechanism 150 has completed pressing the other end of the target object 121, the injection mechanism 200 needs to be separated from the target object 121. The injection mechanism 200 moves along one end of the target object 121 (e.g., Figure 3 f), the sample injection mechanism 200 can be separated from the target object 121 relatively smoothly, so that it can be smoothly withdrawn from the storage mechanism 130.

[0071] Therefore, the present technical solution, through the cooperation of the limiting mechanism 140 and the pressing mechanism 150, clamps the target object 121 in the placement cavity 130c, preventing it from shaking, so that the sampling mechanism 200 can be separated from the target object 121 more smoothly and exit the storage mechanism 130 more smoothly, thereby improving the overall reliability and stability of the instrument and effectively avoiding the impact on continuous operation.

[0072] In some embodiments, as Figure 6 、 Figure 8 and Figure 10 As shown, in order to ensure the limiting effect on one end of the target object 121, a fixed bracket 141 and a shift rod 145 can be set in the limiting mechanism 140, wherein the fixed bracket 141 is "L"-shaped, and its lower end is fixedly set on the outside of the storage mechanism 130, and the shift rod 145 is an irregular piece.

[0073] Specifically, one end of the fixing bracket 141 is disposed on the outside of the storage mechanism 130 , and a plurality of through holes (not shown) are provided on a surface of the fixing bracket 141 .

[0074] One end surface of the shift rod 145 is fitted on one side end surface of the fixing bracket 141 and is fixed on the fixing bracket 141 by means of a rivet or a screw passing through a through hole.

[0075] The shift rod 145 can move relatively along one end surface of the fixing bracket 141 .

[0076] One end of the shift rod 145 extends into the square slot 130 a of the storage mechanism 130 .

[0077] In some embodiments, as Figure 6 、 Figure 8 and Figure 10 As shown, in order to improve the control effect of the gear lever 145, a positioning rod 142, a linkage rod 143, a spring 144 and a control rod 146 can be provided in the limiting mechanism 140.

[0078] One end of the positioning rod 142 passes through the through hole and is fixed on the lower side of the fixing bracket 141 .

[0079] The linkage rod 143 passes through the surface of the shift rod 145 and is fixedly arranged on the upper end of the shift rod 145 .

[0080] One end of the spring 144 is disposed on the positioning rod 142 .

[0081] The other end of the spring 144 is disposed on the linkage rod 143 .

[0082] The operating rod 146 is arranged on the upper end side of the gear lever 145 and on the outer side of the linkage rod 143 , and is arranged opposite to the positioning rod 142 . The operating rod 146 can be used to control the gear lever 145 to move on the fixed bracket 14 .

[0083] In some embodiments, as Figure 10 As shown, a radially arranged slot 130 b is provided on the storage mechanism 130 .

[0084] The end of the shift rod 145 not provided with the linkage rod 143 extends into the storage mechanism 130 through the slot 130 b.

[0085] The lever 145 extending into the storage mechanism 130 limits and fixes one end of the target object 121 .

[0086] In a normal state, one end of the shift rod 145 extends into the square slot 130 a to limit the first side (or front side) of the target object 121 .

[0087] When the target object 121 needs to flow to the next processing step, the operating rod 146 is pushed toward the side of the square groove 130a. At this time, the gear lever 145 extending into the square groove 130a can move along the bottom side of the notch 130b and separate from the square groove 130a.

[0088] After the operating lever 146 is released, the shift lever 145 returns to its original position and extends into the square groove 130a through the notch 130b.

[0089] In some embodiments, as Figure 6 、 Figure 8 and Figure 11 As shown, in order to ensure the limiting effect on one end of the target object 121, a sample collecting push plate (151a, 151b) and a film bin pressing plate 152 can be set in the pressing mechanism 150, wherein the sample collecting push plate (151a, 151b) is a door-shaped structure.

[0090] The film bin pressing plate 152 is a square structure.

[0091] Specifically, a portion of the sample receiving push plate (corresponding to 151a) is disposed outside the other end of the storage mechanism 130.

[0092] The other part of the sample receiving and pushing plate (corresponding to 151b) is arranged in the placement cavity 130c.

[0093] The film magazine pressure plate is arranged at the upper end of the placement cavity 130c and is arranged in contact with the other part of the sample receiving push plate (corresponding to 151b).

[0094] In some embodiments, as Figure 8 As shown, in order to improve the limiting effect on the other end of the target object 121, a protrusion 152a can be provided at the upper end of the film magazine pressure plate 132 along one side of the placement cavity 130c, wherein the protrusions 152a are symmetrically provided.

[0095] Furthermore, another portion of the sample receiving push plate (corresponding to 151 b ) cooperates with the protruding piece 152 a to press the other end of the target object 121 .

[0096] In some embodiments, as Figure 9As shown, in order to improve the control effect of the reciprocating movement of the pressing mechanism 150, at least a transmission mechanism 300 can be set on the lower end surface of the storage mechanism 130. The transmission mechanism 300 is arranged in conjunction with the sample receiving push plates (151a, 151b) to control the axial reciprocating movement of the sample receiving push plates (151a, 151b) along the storage mechanism 130.

[0097] The transmission mechanism 300 at least includes a slide rod 133 , a connecting block 134 , a transmission assembly 135 , a transmission belt 136 , a pulley 137 and a motor 138 .

[0098] The slide bar 133 is axially disposed at the bottom of the storage mechanism 130 , and has sliding grooves (not shown) extending outwardly from both ends thereof.

[0099] The connecting block 134 is sleeved on a sliding groove (not shown) of the sliding rod 133 .

[0100] The connecting block 134 is fixedly connected to a portion of the sample receiving push plate (corresponding to 151 a ), and the transmission component 135 is arranged on the outside of the portion of the sample receiving push plate (corresponding to 151 a ).

[0101] The pulley 137 and the motor 138 are disposed opposite to each other at the bottom of the storage mechanism 130 and are connected by a conveyor belt 136 .

[0102] The conveyor belt 136 passes through the opposite surface of the conveying component 135 and a portion of the sample receiving push plate (corresponding to 151a). When the motor 138 is working, the conveyor belt 136 and the pulley 137 rotate.

[0103] The conveyor belt 136 and the conveyor assembly 135 apply a rotational torque to the connecting block 134, thereby driving a portion of the sample receiving push plate (corresponding to 151a) to reciprocate along the slide rod 133, thereby controlling the sample receiving push plate (151a, 151b) and the film bin pressure plate 152 to move in the square groove 130a.

[0104] In some embodiments, as Figure 2 and Figure 3 As shown, in order to ensure the reliability of the sample feeding mechanism 200 in gripping and placing the target object 121 , a linear guide rail 210 , a motor module 220 , a rotating assembly 230 , a linear motion module 310 and a film magazine clamping mechanism 350 may be provided in the sample feeding mechanism 200 .

[0105] The linear guide rail 210 is used to fix the motor module 220 and the rotating assembly 230 , and provides a radial movable track for the motor module 220 .

[0106] The motor module 220 provides a rotational torque to the rotating component 230 to control the rotation of the rotating component 230 .

[0107] The linear motion module 310 provides an axial motion track and torque for the film magazine clamping mechanism 350 .

[0108] like Figure 5 As shown, the film magazine clamping mechanism 350 is used to clamp the target object 121 in the sample feeding carriage 120, that is, the linear guide rail assembly 100 drives the film magazine clamping mechanism 350 to the top of the sample feeding carriage 120, and then controls the rotating assembly 230 to rotate about 45 degrees through the motor module 220 to clamp the target object 121, and then rotates the linear motion module 310 to the linear slide 210 and the horizontal position. At this time, the linear guide rail assembly 100 moves the storage mechanism 130 to the bottom of the film magazine clamping mechanism 350, and the motor module 220 controls the rotating assembly 230 to work, and places the target object 121 clamped by the film magazine clamping mechanism 350 into the storage mechanism 130.

[0109] Specifically, the linear guide rail 210 is vertically arranged on the working platform 10a.

[0110] The motor module 220 is movably disposed on the linear guide rail 210 to control the reciprocating movement of the motor module 220 on the linear guide rail 210 .

[0111] One end of the rotating assembly 230 is connected to the rotating shaft of the linear guide rail 220 to control the circumferential rotation of the rotating assembly 230 .

[0112] The inner side of the linear motion module 310 is fixedly connected to the other end of the rotating assembly 230 , and the rotating rotating assembly 230 can drive the linear motion module 310 to rotate.

[0113] One end of the film magazine clamping mechanism 350 is fixedly connected to the linear motion module 310 , and the linear motion module 310 is used to control the axial movement of the film magazine clamping mechanism 350 .

[0114] In some embodiments, as Figure 4 and Figure 5 As shown, the film magazine clamping mechanism 350 is used to clamp the target object 121 in the sample introduction vehicle 120, and the rotating assembly 230 controls the film magazine clamping mechanism 350 to place the clamped target object 121 into the placement cavity.

[0115] like Figure 6 As shown, the linear motion module 310 includes at least a motor 320a, a slide rod 320b and a slider 330, wherein the ends of the slide rod 320b are respectively arranged at both ends of the linear motion module 310, and the slider 330 is sleeved in the slide rod 320b to provide a moving stroke for the slider 330.

[0116] The motor 320a is disposed at one end of the slide bar 320b, and the rotation shaft of the motor 320a is movably connected to the one end of the slide bar 320b.

[0117] Further, if Figure 7 As shown, one end of the film bin clamping mechanism 350 is fixedly connected to the outer side of the slider 330. When the motor 320a rotates, the slide bar 320b rotates accordingly, thereby driving the slider 330 to move to control the movement of the film bin clamping mechanism 350. When the slider 330 moves along one end of the motor 320a, the film bin clamping mechanism 350 is in the exit state.

[0118] like Figure 7 As shown, symmetrical gripping arms 351 are provided at the other end of the film magazine clamping mechanism 350 , and an opening 350 a for accommodating the target object 121 is formed between the two gripping arms 351 .

[0119] The inner wall of the gripping arm 351 is provided with a slot 352, and the slot 352 is aligned with the protrusion 121a ( Figure 3 shown) are compatible.

[0120] like Figure 1 As shown, multiple positioning plates 122 and a spring 123 are set on one side of the transfer vehicle 120, and the target object 121 is placed on the adjacent side of the positioning plate 122. The upper end of the positioning plate 122 is connected to the through hole extending from the transfer vehicle 120 through the spring 123 to position the positioning plate 122.

[0121] When the film magazine clamping mechanism 350 clamps the target object 121 , the gripping arm 351 of the film magazine clamping mechanism 350 pushes the target object 121 toward the positioning plate 122 , so that the target object 121 is confined in a clampable state.

[0122] like Figure 1 As shown, the linear guide assembly 100 at least includes a slide rail 110 , a motor (not shown), a transmission belt 111 and a rotating ring 112 .

[0123] The transfer vehicle 120 is disposed at the upper end of the linear guide assembly 100 , and is driven by a motor (not shown) to drive the transmission belt 111 to move, so that the transfer vehicle 120 can move along the slide rail 110 .

[0124] Specifically, after the power is turned on, the sample feeding mechanism 200 operates according to the set program, and the linear guide assembly 100 cooperates to clamp the target object 121 (such as a slide chamber) from the transfer vehicle 120 and exit the transfer vehicle 120.

[0125] The linear guide assembly 100 moves to the storage mechanism 130 of the target object 121 (such as a slide chamber), and the sample feeding mechanism 200 rotates to a horizontal position with the linear motion module 310. At this time, one side of the target object 121 is close to the limiting mechanism 140, and the pressing mechanism 150 moves to close to the other side of the target object 121 (such as a slide chamber) (a slide chamber pressure plate 152 is fixed on the pressing mechanism 150. At this time, the slide chamber pressure plate 152 presses the top of the target object 121 (such as a slide chamber) to prevent the target object 121 (such as a slide chamber) from flipping up when the linear motion module 310 and the slide chamber clamping mechanism 350 exit the target object 121 (such as a slide chamber)). The linear motion module 310 moves and exits the target object 121 (such as a slide chamber) with the slide chamber clamping mechanism 350.

[0126] The above description is only part of the implementation methods of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
