Description

Technical Field

[0001] This invention relates to the field of reagent tray assembly equipment technology, specifically to a reagent tray synchronous film separation device and method. Background Technology

[0002] Sample analyzers are mainly used for the determination of biochemical and chemical components in clinical blood or other liquid samples. They are one of the commonly used testing instruments in clinical analysis. Sample analyzers usually include a reagent tray and use the reagent tray to test the sample.

[0003] In the prior art, reagent trays generally include a reagent tray body and a cover plate, which are assembled by attaching the cover plate to the reagent tray body. However, the use of a cover plate results in a higher cost for the reagent tray. Therefore, the cover plate in the prior art is replaced by an adhesive film. During assembly, the adhesive film needs to be peeled off from the material strip and then pasted onto the reagent tray body, so that the flow channels on the reagent tray body are closed to form solution channels.

[0004] During assembly, the adhesive film on the material strip needs to be removed by a robotic arm. In actual use, the adhesive film is supplied using the utility model patent disclosed in application number CN202120837230.9. This utility model is specifically a QR code supply device for a reagent tray retainer bonding equipment, including a mounting base for installation on the reagent tray retainer bonding equipment. A QR code carrier plate is provided on the upper end of the mounting base, and an L-shaped support frame is provided on the mounting base. A crossbar is installed on the L-shaped support frame, and the two ends of the crossbar are used to install QR code rolls. QR code winding assemblies are provided on both sides of the mounting base, and a first tension roller and a second tension roller are provided on both sides of the support base. A pressing assembly is provided on the QR code carrier plate. The pressing assembly includes a smoothing roller, a tension spring, a connecting block, and a smoothing roller bracket. The smoothing roller bracket is fixedly installed on the QR code carrier plate, and the smoothing roller is rotatably installed on the smoothing roller bracket, with its two ends extending out of the smoothing roller bracket and connected to one of the connecting blocks. It is mainly used to fix the QR code supply station in the reagent tray retainer bonding equipment to achieve the purpose of automated QR code supply.

[0005] However, in actual use, it was found that after the adhesive membrane was peeled off and the robotic arm was used to pick up the adhesive membrane, it would still follow the movement to separate the adhesive membrane. During the separation process, the robotic arm needs to move with the adhesive membrane, which cannot achieve synchronous separation of the adhesive membrane on the material strip. The robotic arm is prone to large positioning errors during the following process, which can easily cause large positioning errors between the adhesive membrane and the reagent tray body. Summary of the Invention

[0006] The purpose of this invention is to provide a reagent tray synchronous film separation device and method, which can effectively solve the technical problems in the prior art that cannot achieve synchronous film separation of the film adhering to the material strip, and that the robot arm is prone to large positioning errors during the following process, and that the film adhering to the reagent tray body is prone to large positioning errors.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0013] in,

The motor is mounted on the bracket and connected to the first roller. The first roller is located below the second roller. The first roller and the second roller are connected by a gear mechanism.

[0015] The second drive assembly includes a telescopic rod, a clutch, a gear, and a rack.

The telescopic rod is fixedly mounted on the frame, with its movable end connected to the bracket. The rack is fixedly mounted on the frame, and the gear and rack mesh with each other.

[0016] Furthermore, a roll assembly is provided on the frame, which is used to wind up the base film.

[0017] The bracket is provided with a sliding groove, and a slider is slidably arranged in the sliding groove. A second roller is rotatably mounted on the slider. A spring is provided in the sliding groove. The upper end of the spring is connected to the bracket, and the lower end is connected to the slider. An adjustment mechanism is provided on the bracket. The adjustment mechanism includes a crossbar and an adjustment rod. The crossbar is horizontally arranged and fixedly mounted on the bracket. The crossbar is perpendicular to the sliding groove. The adjustment rod is rotatably mounted on the slider. The adjustment rod is provided with a notch, which corresponds to the crossbar.

[0018] The adjusting rod has a handle at one end.

[0019] Furthermore, limit protrusions are provided on both sides of the slider, and a limit area is formed between the limit protrusions. The limit area is slidably connected to the inner wall of the groove.

[0020] The slider has a guide hole, the bracket has a guide rod that passes through the guide hole, and the spring is fitted onto the guide rod.

[0021] Preferably, a guide sleeve or a linear bearing is provided inside the guide hole.

[0022] Furthermore, the bracket is mounted on the frame via a sliding assembly, which includes a slide rail fixedly mounted on the frame and a sliding block mounted on the bracket, with the sliding block slidingly engaging with the slide rail.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] In practical use, this invention ensures that the robotic arm remains in the same position when adsorbing the adhesive film, preventing synchronous movement during peeling and reducing positioning errors. During operation, the motor is activated, disengaging the clutch, and the telescopic rod pushes the support to a preset position. Then, the motor drives the first and second rollers to rotate, moving the bottom film of the conveyor belt and partially separating the adhesive film from the bottom film. At this point, the adhesive film is in the preset position, corresponding to the robotic arm's preset position. The holes on the bottom film are checked to ensure the adhesive film reaches the preset position; once the preset position is reached, the motor stops. The robotic arm then moves to the adhesive film position. At this point, the adhesive membrane is in a preset position, the robotic arm is in a preset position, the vacuum of the robotic arm is activated, the vacuum is maintained, and the adhesive membrane is adsorbed; at this point, the motor is powered off, the enable is disconnected, and the clutch is connected to the rotating shaft; at this point, the telescopic rod pulls the bracket backward, causing the bracket to reset. During the reset process, the gear is forced to rotate on the rack, the gear drives the first roller to rotate, and the first and second rollers pull the bottom membrane backward; during the return stroke, the return stroke of the telescopic rod is equal to the return stroke of the entire mechanism, and is also equal to the forward stroke of the adhesive membrane in the bottom mold, thus ensuring synchronous membrane separation while the positions of the adhesive membrane and the robotic arm remain unchanged;

[0027] After completing the synchronous membrane separation, the robotic arm adsorbs and moves the adhesive membrane to the center position of the light source and camera of the reagent tray assembly equipment for photographing, identification and positioning; the robotic arm compensates and adjusts based on the adhesive membrane position information fed back by the camera, and then attaches the adhesive membrane to the product.

[0042] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0043] See Figures 1-5 This embodiment discloses a reagent tray synchronous film separation device, including a support 101, a material strip channel 102, a pressing assembly 103, a first driving assembly 104, and a second driving assembly 105. The support 101 is slidably mounted on the frame 106 of the reagent tray assembly equipment; the material strip channel 102 is located on top of the support 101; the pressing assembly 103 is mounted on the support 101 and located above the material strip channel 102 to press the material strip 132 in the material strip channel 102; the first driving assembly 104 is used to drive the material strip 132 to move in the material strip channel 102 and to partially peel off the film 131 on the material strip 132; the second driving assembly 105 is connected to the support 101 and is used to drive the support 101 to move on the frame 106, while simultaneously driving the first driving assembly 104.

[0044] in,

[0045] The first drive assembly 104 includes a first roller 107, a second roller 108, and a motor 109. The first roller 107 and the second roller 108 are both rotatably mounted on the bracket 101. The motor 109 is mounted on the bracket 101 and connected to the first roller 107. The first roller 107 is located below the second roller 108. The first roller 107 and the second roller 108 are connected by a gear mechanism 110.

[0046] The second drive assembly 105 includes a telescopic rod 111, a clutch 112, a gear 113, and a rack 114. The gear 113 is connected to a rotating shaft 115, which is rotatably mounted on a bracket 101 and connected to the first roller 107 via the clutch 112. The telescopic rod 111 is fixedly mounted on a frame 106, with its movable end connected to the bracket 101. The rack 114 is fixedly mounted on the frame 106, and the gear 113 and the rack 114 mesh with each other.

[0047] The frame 106 is equipped with a winding assembly 116, which is used to wind up the bottom film of the material strip to prevent the bottom film from accumulating. In this embodiment, the material strip consists of an adhesive film and a bottom film disposed on the adhesive film.

[0048] The bracket 101 is provided with a sliding groove 117, and a slider 118 is slidably disposed in the sliding groove 117. A second roller 108 is rotatably mounted on the slider 118. A spring is provided in the sliding groove 117, with its upper end connected to the bracket 101 and its lower end connected to the slider 118. An adjustment mechanism 119 is provided on the bracket 101. The adjustment mechanism 119 includes a crossbar 120 and an adjustment rod 121. The crossbar 120 is horizontally disposed and fixedly mounted on the bracket 101, and the crossbar 120 is perpendicular to the sliding groove 117. The adjustment rod 121 is rotatably mounted on the slider 118, and a notch 122 is provided on the adjustment rod 121, which corresponds to the crossbar 120.

[0049] In this embodiment, the second roller 108 is mounted on the bracket 101 via a slider 118, allowing the position of the second roller 108 on the bracket 101 to be adjustable. A spring ensures that the second roller 108 can contact the first roller 107. When the motor 109 drives the first roller 107 to rotate, the gear mechanism 110 causes the second roller 108 to rotate accordingly, thereby driving the material belt 132. The crossbar 120 is horizontally positioned and fixedly mounted on the bracket 101, perpendicular to the slide 117. The adjusting rod 121 is rotatably mounted on the slider. On 118, the adjusting rod 121 is provided with a notch 122, which corresponds to the crossbar 120. So when changing the material strip 132, only the adjusting rod 121 needs to be rotated. Since the adjusting rod 121 is provided with a notch 122, a cam mechanism can be formed at the position of the notch 122. When the adjusting rod 121 is rotated, the back side of the adjusting rod 121 at the notch 122 contacts the crossbar 120, thereby lifting the slider 118 upward. At this time, the spring is compressed, and the gap between the first roller 107 and the second roller 108 increases, so as to facilitate the rapid replacement of the material strip 132.

[0050] The adjusting rod 121 has a handle 123 at its end. The side of the adjusting rod 121 end has a flat surface 124 with a threaded hole. The handle 123 is threaded into this hole, facilitating quick assembly and disassembly of the handle 123.

[0051] The adjusting rod 121 is rotatably mounted on the slider 118 via a bearing, which makes the adjusting rod 121 rotate more smoothly.

[0052] Furthermore, limiting protrusions 125 are provided on both sides of the slider 118, forming a limiting area between the limiting protrusions 125. The limiting area is slidably connected to the inner wall of the slide groove 117. This makes the slider 118 more stable when moving.

[0053] Furthermore, in some specific embodiments, the slider 118 is provided with a guide hole 126, and the bracket 101 is provided with a guide rod 127 passing through the guide hole 126, with a spring fitted onto the guide rod 127. This makes the slider 118 more stable when moving.

[0054] The guide hole 126 is provided with a guide sleeve or a linear bearing. In this embodiment, the guide hole 126 is provided with a linear bearing.

[0055] Both the first roller 107 and the second roller 108 are provided with rubber layers.

[0056] Among them, the notch 122 has arc-shaped surfaces 128 on both sides that connect with the side of the adjusting rod 121, which makes it more convenient to rotate the adjusting rod.

[0057] In this embodiment, the pressing assembly 103 is mainly used to enable the material belt 132 to adhere to the material belt channel 102 and provide pre-tension force for the material belt 132.

[0058] The bracket 101 is mounted on the frame 106 via a sliding assembly. The sliding assembly includes a slide rail fixedly mounted on the frame 106 and a sliding block mounted on the bracket 101, with the sliding block slidingly engaging with the slide rail. The sliding block and slide rail ensure greater stability of the bracket 101 during movement.

[0059] The frame 106 is provided with a fixing groove, and the gear 113 is fixedly installed in the fixing groove. Furthermore, the rack 114 is fixedly installed in the fixing groove by bolts.

[0060] The telescopic rod can be electric, hydraulic, or pneumatic. In practical applications, a pneumatic telescopic rod is preferred.

[0061] Furthermore, a sensor is installed on the frame 106 to detect whether the support 101 has reached the preset position. The sensor is connected to the telescopic rod. The sensor is connected to the telescopic rod through the control system of the reagent tray assembly equipment to achieve automatic stopping after reaching the preset position.

[0062] The gear mechanism 110 includes a driving gear 129 and a driven gear 130. The driving gear 129 is mounted on the first roller 107, and the driven gear 130 is mounted on the second roller 108. The driving gear 129 and the driven gear 130 mesh with each other.

[0063] In addition, this embodiment also discloses a reagent tray synchronous membrane separation method, which includes using the above-mentioned reagent tray synchronous membrane separation device to perform membrane separation;

[0064] The specific membrane separation process is as follows:

[0065] Step 1: The motor 109 is enabled and the clutch 112 is disengaged, and the telescopic rod 111 pushes the bracket 101 to the preset position;

[0066] Step 2: Motor 109 drives the first roller 107 and the second roller 108 to rotate, causing the bottom film of the material belt 132 to move, thereby partially separating the adhesive film 131 from the bottom film. At this time, the adhesive film 131 is located at a preset position, which corresponds to the preset position of the robot arm. The holes on the bottom film are detected to ensure that the adhesive film 131 reaches the preset position. After reaching the preset position, motor 109 stops.

[0067] Step 3: The robotic arm of the reagent tray assembly equipment moves to the position of the mucosa 131. At this time, the mucosa 131 is in the preset position and the robotic arm is in the preset position. The vacuum of the robotic arm is turned on, the vacuum is maintained and the mucosa 131 is adsorbed.

[0068] Step 4: De-energize motor 109, disconnect the enable, and connect clutch 112 to shaft 115.

[0069] Step 5: The telescopic rod 111 pulls the bracket 101 backward, causing the bracket 101 to reset. During the reset process, the gear 113 is forced to rotate on the rack 114. The gear 113 drives the first roller 107 to rotate. The first roller 107 and the second roller 108 pull the bottom film backward. During the return stroke, the return stroke of the telescopic rod is equal to the return stroke of the entire mechanism, and is also equal to the forward stroke of the adhesive film 131 in the bottom mold. This ensures that synchronous film separation is achieved while the positions of the adhesive film 131 and the robot remain unchanged.

[0070] Step 6: After completing the synchronous membrane separation, the robotic arm adsorbs and moves the adhesive membrane 131 to the center position of the light source and camera of the reagent tray assembly equipment for photographing, identification and positioning.

[0071] Step 7: The robotic arm uses the position information of the adhesive membrane 131 fed back by the camera to make compensation adjustments and attach the adhesive membrane 131 to the product.

[0072] It should be noted that in actual use, the pitch circle dimension of gear 113 must be the same as the outer circle dimension of the first roller 107 and the second roller 108. This ensures that the amount of material retracted by the mechanism corresponds to the amount of material rolled away by the first roller 107 and the second roller 108, thus achieving synchronous film separation. Previous mechanisms and approaches relied on dual-path control and matching, which was a very cumbersome process and prone to cumulative errors. The structure disclosed in this embodiment is much simpler to control and debug.

[0073] Although preferred embodiments of the invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the invention.

[0074] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
