Description

Technical Field

[0001] This utility model relates to the field of coagulation analyzer technology, specifically a three-axis stepper assembly for a coagulation analyzer. Background Technology

[0002] A coagulation analyzer is a medical instrument used to analyze blood clotting function. It assesses the state of coagulation function in the body by measuring indicators such as clotting time and clotting strength of blood samples. When using a coagulation analyzer, a sample dispensing needle is needed to pick up and deliver the sample, and the movement of the sample dispensing needle can be controlled by a three-axis stepper assembly.

[0003] Currently, the three-axis stepper components used in coagulation analyzers are mostly controlled by lead screw transmission. In order to maintain the stability of lead screw transmission, it is usually necessary to manually apply lubricant to the lead screw frequently, which increases the workload of personnel.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a three-axis stepping component for coagulation analyzers. Utility Model Content

[0005] The purpose of this invention is to provide a three-axis stepper assembly for a coagulation analyzer to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a three-axis stepping assembly for a coagulation analyzer, comprising a support and a lubrication assembly. A translation assembly is provided on the top of the support, and an electric cylinder is mounted on the top of the translation assembly. A sliding box is connected to the end of the electric cylinder. A lifting assembly is provided inside the sliding box. The lubrication assembly is located above the lifting assembly. The lubrication assembly includes a support plate, a Y-shaped rod, a pulley, a limiting block, a return spring, a guide block, a pressure ring, a sponge, a fixing ring, and a liquid outlet. A Y-shaped rod is slidably connected to the upper end of the support plate, and a pulley is mounted on one end of the Y-shaped rod. A limiting block is fixed to one side of the sliding box. A return spring is sleeved on the outer side of one end of the Y-shaped rod, and a guide block is slidably connected to the end of the Y-shaped rod. A pressure ring is fixed to the bottom of the guide block. A sponge is provided at the bottom of the pressure ring, and a fixing ring is provided at the bottom of the sponge. A liquid outlet is opened at the lower inner end of the fixing ring.

[0007] Furthermore, the translation component includes a first motor, a first synchronous pulley, and a first synchronous belt. The top of the first motor is connected to the first synchronous pulley, and the first synchronous belt is disposed on the outer side of the first synchronous pulley.

[0008] Furthermore, the translation component also includes a base and a guide rail. The base is fixed to one side of the first synchronous belt, and the guide rail is slidably connected to the lower end of the base. The guide rail is fixedly connected to the support, and the base is slidably connected to the sliding box.

[0009] Furthermore, the lifting assembly includes a second motor, a second synchronous pulley, a second synchronous belt, and a third synchronous pulley. The bottom of the second motor is connected to the second synchronous pulley, and the second synchronous belt is provided on the outer side of the second synchronous pulley. The third synchronous pulley is provided inside one end of the second synchronous belt.

[0010] Furthermore, the lifting assembly also includes a lead screw, a lifting seat, and a guide rod. The lead screw is installed inside the third synchronous pulley, and a lifting seat is provided on the outer side of the upper end of the lead screw. A guide rod is slidably connected to the middle of the lifting seat.

[0011] Furthermore, one end of the lifting seat is connected to a fluid replenishment component, which includes an oil tank, iron balls, and a stop bar. The lower end of the oil tank is equipped with iron balls, and the lower end of the oil tank is fixed with a stop bar.

[0012] Furthermore, the fluid replenishment assembly also includes a diversion pipe and a fluid inlet. The diversion pipe is fixed to the outside of the fixing ring and is connected to the inside of the oil storage tank. A fluid inlet is provided on the upper outer side of the fixing ring.

[0013] Furthermore, the fluid replenishment assembly also includes a spring seat and a magnetic block. The spring seat is fixed to the upper part of one side of the pressure ring, and the end of the spring seat is connected to the magnetic block.

[0014] This invention provides a three-axis stepper assembly for a coagulation analyzer, which has the following advantages:

[0015] 1. This utility model, through the setting of the lubrication component, causes the support plate to move synchronously when the lifting component moves the lifting seat. When the pulley contacts the limit block, the guide block is squeezed by the Y-shaped rod, causing the pressure ring to squeeze the sponge, so that the lubricating oil stored inside the sponge flows out from the outlet on the inner side of the fixed ring. When the pulley separates from the limit block, the return spring will drive the Y-shaped rod to return to its original position. At this time, the sponge will move the pressure ring upward under elastic deformation. In addition, multiple limit blocks are set inside the sliding box. Therefore, when the lifting component is working, it can automatically lubricate the lead screw and the lifting seat, improving the convenience of maintenance.

[0016] 2. This utility model, through the setting of the liquid replenishment component, allows the iron ball to block the bottom of the oil reservoir under the action of gravity, preventing continuous leakage of oil and waste. When the pressure ring moves down, it also causes the spring seat to drive the magnetic block down, allowing the magnetic block to slide down along the cone of the oil reservoir. When it approaches the iron ball, it will attract the iron ball, causing the iron ball to move towards the baffle. At this time, some oil can flow into the diversion pipe through the iron ball. When the sponge drives the pressure ring up, the distance between the magnetic block and the iron ball increases under the obstruction of the baffle, and the magnetic force weakens, so that the iron ball continues to block the bottom of the oil reservoir, thus avoiding excessive waste caused by excessive liquid replenishment at one time.

Detailed Implementation

[0021] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] like Figure 1 and Figure 2As shown, a three-axis stepper assembly for a coagulation analyzer includes a support 1 and a lubrication assembly 6. A translation assembly 2 is mounted on the top of the support 1, and an electric cylinder 3 is mounted on the top of the translation assembly 2. The end of the electric cylinder 3 is connected to a sliding box 4, which can control the left and right position of the sliding box 4. The translation assembly 2 includes a first motor 201, a first synchronous pulley 202, and a first synchronous belt 203. The top of the first motor 201 is connected to the first synchronous pulley 202, and the first synchronous belt 203 is mounted on the outer side of the first synchronous pulley 202. The translation assembly 2 also includes a base 204 and a guide rail 205. The base 204 is fixed to one side of the first synchronous belt 203, and the guide rail 205 is slidably connected to the lower end of the base 204. The guide rail 205 is fixedly connected to the support 1, and the base 204 is slidably connected to the sliding box 4. The first motor 201 drives the first synchronous pulley 202 to rotate, which causes the first synchronous belt 203 to pull the base 204, making it move on the guide rail 205. By sliding, the forward and backward position of the sliding box 4 can be controlled. The sliding box 4 is equipped with a lifting assembly 5, which includes a second motor 501, a second synchronous pulley 502, a second synchronous belt 503, and a third synchronous pulley 504. The bottom of the second motor 501 is connected to the second synchronous pulley 502, and the second synchronous belt 503 is provided on the outer side of the second synchronous pulley 502. The third synchronous pulley 504 is provided inside one end of the second synchronous belt 503. The lifting assembly 5 also includes a lead screw 505, a lifting seat 506, and a guide rod 507. The lead screw 505 is installed inside the third synchronous pulley 504, and the lifting seat 506 is provided on the outer side of the upper end of the lead screw 505. The guide rod 507 is slidably connected to the middle of the lifting seat 506. The second motor 501 drives the lead screw 505 to rotate through the second synchronous pulley 502, the second synchronous belt 503, and the third synchronous pulley 504, so that the lifting seat 506 can slide along the guide rod 507 to adjust the height of the sampling needle.

[0023] like Figure 2 and Figure 3As shown, the lubrication assembly 6 is located on the upper part of the lifting assembly 5. The lubrication assembly 6 includes a support plate 601, a Y-shaped rod 602, a pulley 603, a limiting block 604, a return spring 605, a guide block 606, a pressure ring 607, a sponge 608, a fixing ring 609, and a liquid outlet 610. The Y-shaped rod 602 is slidably connected to the upper end of the support plate 601, and a pulley 603 is installed at one end of the Y-shaped rod 602. A limiting block 604 is fixed to one side of the inside of the sliding box 4. A return spring 605 is sleeved on the outer side of one end of the Y-shaped rod 602, and a guide block 606 is slidably connected to the end of the Y-shaped rod 602. The bottom of the guide block 606 is... A pressure ring 607 is fixed in place. A return spring 605 drives the Y-shaped rod 602 to return to its original position. A sponge 608 is located at the bottom of the pressure ring 607, and a fixing ring 609 is located at the bottom of the sponge 608. An outlet 610 is located at the lower inner end of the fixing ring 609. When the lifting assembly 5 moves the lifting seat 506, the support plate 601 moves synchronously. When the pulley 603 contacts the limiting block 604, the Y-shaped rod 602 presses against the guide block 606, causing the pressure ring 607 to press against the sponge 608. This allows the lubricating oil stored inside the sponge 608 to flow out from the outlet 610 inside the fixing ring 609. The lifting seat 506... One end is connected to a fluid replenishment component 7, which includes an oil reservoir 701, an iron ball 702, and a baffle 703. The iron ball 702 is installed inside the lower end of the oil reservoir 701, and the baffle 703 is fixed to the lower end of the oil reservoir 701. The iron ball 702 will block the bottom of the oil reservoir 701 under the action of gravity, preventing continuous leakage of oil and waste. The fluid replenishment component 7 also includes a diversion pipe 704 and a fluid inlet 705. The diversion pipe 704 is fixed to the outside of the fixing ring 609 and is connected to the inside of the oil reservoir 701. The upper outer end of the fixing ring 609 has a fluid inlet 705, through which oil can pass. 05 enters the fixed ring 609 to replenish the oil inside the sponge 608. The replenishment component 7 also includes a spring seat 706 and a magnetic block 707. The spring seat 706 is fixed on the upper part of one side of the pressure ring 607, and the end of the spring seat 706 is connected to the magnetic block 707. When the pressure ring 607 moves down, the spring seat 706 will also drive the magnetic block 707 to move down, so that the magnetic block 707 slides down along the cone of the oil reservoir 701. When it approaches the iron ball 702, it will attract the iron ball 702, so that the iron ball 702 moves towards the stop bar 703. At this time, some oil can flow into the diversion pipe 704 through the iron ball 702.

[0024] In summary, this three-axis stepper assembly for coagulation analyzers, when used, first according to... Figure 1 , Figure 2 and Figure 3In the structure shown, the first motor 201 drives the first synchronous pulley 202 to rotate, which causes the first synchronous belt 203 to pull the base 204, making it slide on the guide rail 205, thus controlling the front and rear position of the sliding box 4. The electric cylinder 3 controls the left and right position of the sliding box 4, moving the sampling needle to the designated position. Then, the second motor 501 drives the lead screw 505 to rotate through the second synchronous pulley 502, the second synchronous belt 503, and the third synchronous pulley 504, which causes the lifting seat 506 to slide along the guide rod 507 to adjust the height of the sampling needle. Then, when the lifting assembly 5 moves the lifting seat 506, the support plate 601 moves synchronously. When the pulley 603 contacts the limit block 604, the Y-shaped rod 602 squeezes the guide block 606, causing the pressure ring 607 to squeeze the sponge 608, thereby releasing the lubricating oil stored inside the sponge 608. Liquid flows out from the outlet 610 inside the fixed ring 609. Simultaneously, when the pressure ring 607 moves downwards, the spring seat 706 causes the magnetic block 707 to move downwards, allowing it to slide down along the cone-shaped portion of the oil reservoir 701. When it approaches the iron ball 702, it attracts the iron ball 702, causing it to move towards the stop lever 703. At this point, some oil can flow through the iron ball 702 into the diverter pipe 704. Finally, when the pulley 60... When the 3rd part separates from the limit block 604, the reset spring 605 will drive the Y-shaped rod 602 to reset. At this time, the sponge 608 will drive the pressure ring 607 to move upward under elastic deformation. When the sponge 608 drives the pressure ring 607 to move upward, under the obstruction of the stop rod 703, the distance between the magnetic block 707 and the iron ball 702 becomes farther, the magnetic force weakens, and the iron ball 702 will block the bottom of the oil tank 701 under the action of gravity, so as to prevent the oil from continuously leaking out and causing waste.
