[0035] As shown in the figure, the embodiment of the utility model provides a film ejector, comprising a body 1, wherein the body 1 is provided with a supporting surface 11, and the supporting surface 11 is used to place a carrier;

[0036] A limiting structure 2 is formed on the periphery of the supporting surface 11 to limit the surroundings of the carrier;

[0037] The supporting surface 11 is recessed downward from its surface to form a recessed area 3 , and the recessed area 3 at least partially extends to the end surface of the body 1 , so that the carrier located in the recessed area 3 is suspended in the air.

[0038] The present application provides a film ejector, comprising a body 1, the body 1 being provided with a supporting surface 11, the supporting surface 11 being used to place a carrier; a limiting structure 2 is formed by the outer periphery of the supporting surface 11 to limit the surroundings of the carrier; the supporting surface 11 is recessed downward from its surface to form a recessed area 3, and the recessed area 3 at least partially extends to the end surface of the body 1, so that the carrier located in the recessed area 3 is suspended in the air. The film ejector provided by the present application utilizes the setting of the recessed area 3 to partially suspend the carrier supported on the supporting surface 11, so that it is convenient for an operator to insert his fingers into the carrier for taking and placing, which can improve the efficiency of taking and placing the carrier, and can also reduce the accidental occurrence of damage to the carrier.

[0039] Specifically, the push-piece seat body 1 provided by the present application has a supporting surface 11, and the carrier is placed on the supporting surface 11, and the support surface 11 is formed by the outer periphery to limit the position of the limiting structure 2, so as to ensure that the moving range of the carrier in all directions is controllably limited, and its position remains stable when the carrier moves or pushes the piece. Moreover, the supporting surface 11 is recessed downward from its surface to form a recessed area 3, and the recessed area 3 at least partially extends to the end surface of the body 1, so that the carrier placed on the supporting surface 11 is suspended in the recessed area 3, and the operator can extend one finger into the recessed area 3, approach the carrier from the bottom of the carrier, and cooperate with the finger approaching the carrier from the top of the carrier, so that the carrier can be easily and firmly pinched and taken out, and accidents are not easy to occur even with gloves.

[0040] The present application utilizes the recessed area 3 provided on the ejector seat to change the contact surface between the hand or the clamping claw when taking and placing the carrier from the thin side of the carrier to the top and bottom surfaces of the carrier, thereby increasing the contact surface and greatly improving the stability and convenience of taking and placing the carrier.

[0041] In the present application, the recessed area 3 refers to the portion of the ejector seat that is cut off or vacant during molding. The end face can be a surface adjacent to the supporting surface 11 along the length direction of the carrier (usually perpendicular to each other, but can also form a certain angle), or it can be a surface adjacent to the supporting surface 11 along the width direction of the carrier.

[0042] A recessed area 3 is formed between the supporting surface 11 and its adjacent surface. When the carrier is placed on the supporting surface 11, a finger can be extended laterally from the end surface of the body 1 to contact the bottom surface of the carrier, and another finger can cooperate to contact the top surface of the carrier, so that the carrier can be easily taken in and placed.

[0043] Preferably, the recessed area 3 extends to the end surface of the body 1 in the length direction; or,

[0044] The recessed area 3 extends to the end surface of the body 1 in the width direction, and the recessed area 3 is arranged away from the sample area of ​​the carrier.

[0045] The carrier commonly used in the art is in the shape of a rectangle or a rounded rectangle, with the sample area located in the middle of the carrier and a blank area at both ends for clamping or printing barcode information when taking or placing.

[0046] Along the length direction of the main body 1 (i.e., along the length direction of the carrier), the recessed area 3 can be set at the end surface in the length direction. In this case, what is suspended above the recessed area 3 is the blank area of ​​the carrier, rather than the sample area located in the middle. In addition, the recessed area 3 can also be set at the end surface in the width direction of the main body 1, but in this case, the recessed area 3 should avoid the sample area of ​​the carrier to prevent fingers from contacting and damaging the sample during taking and placing. Therefore, the recessed area 3 is set at a position away from the sample area of ​​the carrier, corresponding to the blank area of ​​the carrier.

[0047] Preferably, the width of the recessed area 3 close to the end surface of the body 1 is greater than the width of the recessed area 3 away from the end surface of the body 1 .

[0048] The cross-sectional shape of the recessed area 3 can be any shape, but it is preferably a shape with a wide opening and a tapered shape inwards to match the shape of a human finger, so as to ensure the strength of the ejector seat and facilitate the placement of the carrier. Therefore, it is preferred that the width of the recessed area 3 close to the end surface of the body 1 is greater than the width of the recessed area 3 away from the end surface of the body 1.

[0049] Preferably, the cross-sectional shape of the recessed area 3 is U-shaped, V-shaped or trapezoidal.

[0050] It is further preferred that the cross-sectional shape of the recessed area 3 is U-shaped, V-shaped or trapezoidal, which are shapes with wide openings and tapering inwards, and are easy to process and shape.

[0051] The cross section here refers to the cross section where the recessed area 3 is parallel to the supporting surface 11 .

[0052] Preferably, at least four limiting structures 2 are provided on the outer periphery of the supporting surface 11 .

[0053] The limiting structure 2 can be a continuous or discontinuous limiting mechanism 2 arranged around the supporting surface 11. For ease of processing, preferably at least one limiting structure 2 is arranged on each of the four edges of the supporting surface 11, and at least four limiting structures 2 are arranged on the outer periphery of the supporting surface 11.

[0054] To facilitate operators to take and place the carrier, the overall area of ​​the supporting surface 11 can be slightly larger than the area of ​​the carrier, so that a gap is left between the limiting structure 2 and the carrier. However, since the limiting structure 2 limits the carrier on all sides, during the process of the film pushing head applying force to push the film, the movement of the carrier will be restricted by the limiting structure to ensure the film pushing effect.

[0055] Preferably, along the length direction of the carrier, at least two limiting structures 2 are provided at intervals on the edge of the supporting surface 11 .

[0056] More preferably, at least two limiting structures 2 are provided at intervals on the edge of the supporting surface 11 along the length direction of the carrier, that is, the number of the overall limiting structures is greater than or equal to six, wherein at least two are provided on each of the two edges of the supporting surface 11 along the length direction of the carrier, and the limiting structures 2 located on the same edge are provided at intervals.

[0057] The supporting surface 11 is used to place the carrier. The edge of the supporting surface corresponding to the length direction of the carrier is naturally longer. At least two mutually spaced limiting structures 2 are set on this edge, which can not only ensure sufficient limiting effect, but also leave gaps at the intervals to facilitate operators to take and place the carrier or adjust the position of the carrier, making the operation more flexible.

[0058] Preferably, along the length direction of the carrier, the limiting structures 2 on the edges of both sides of the supporting surface 11 are arranged correspondingly.

[0059] More preferably, the limiting structures 2 on the two side edges of the supporting surface 11 are arranged correspondingly along the length direction of the carrier, that is, the positions and spacings of the limiting structures 2 arranged on the two side edges are symmetrical, and the spacings between the limiting structures 2 are also symmetrical, which is more convenient for finger operation.

[0060] Preferably, the limiting structure 2 protrudes from the outer periphery of the supporting surface 11 , and when the limiting structure 2 and the recessed area 3 are overlapped, a limiting protrusion 21 is formed at each end of the recessed area 3 of the limiting structure 2 .

[0061] More preferably, the limiting structure 2 protrudes from the outer periphery of the supporting surface 11, and the carrier is limited by the height difference with the supporting surface 11, and when the limiting structure 2 and the recessed area 3 are overlapped, the limiting structure 2 forms a limiting convex block 21 at both ends of the recessed area 3, and limits the recessed area 3. The size of the limiting convex block 21 can be freely designed according to the space, as long as there is a structure for limiting the carrier at both ends of the recessed area 3 and plays a limiting role.

[0062] The limiting protrusion 21 and the limiting mechanism 2 protruding from the outer periphery of the supporting surface 11 can both be protrusions on the outer periphery of the supporting surface 11, and their sizes may be different or the same.

[0063] The limiting structure 2 is continuously raised along the edge of the supporting surface 11 to form a long strip, and when the length is greater than the opening width of the recessed area 3, limiting protrusions 21 are naturally formed at both ends of the recessed area 3. When the recessed area 3 is located at one end of the length direction of the body 1, the two limiting protrusions 21 can be located at the two corners of the supporting surface 11.

[0064] A film pushing mechanism comprises a film pushing head assembly 4 and a film pushing seat assembly. The film pushing seat assembly is provided with a film pushing seat and a film pushing seat driving mechanism 5. The film pushing seat is any one of the above-mentioned film pushing seats.

[0065] The present application also provides a film pushing mechanism, including a film pushing head assembly 4 and a film pushing seat assembly. The film pushing seat assembly is provided with a film pushing seat and a film pushing seat driving mechanism 5. The film pushing seat is any of the above-mentioned film pushing seats.

[0066] The film pusher assembly 4 can adopt any film pusher structure that can be used in the art, such as an adaptive film pusher structure, etc. By applying pressure to the sample on the carrier, the carrier translates relative to the film pusher, and the sample can be pushed flat, and the above-mentioned film pusher seats can cooperate.

[0067] The film pusher seat driving mechanism 5 drives the film pusher seat to move, and transports the carrier from the loading position of the carrier to the working position of the film pusher head assembly 4, and then transports it to the discharge position after the film is pushed. During the film pushing process, the carrier moves relative to the film pusher head, which can be achieved by the translation of the film pusher head, or the film pusher seat driving mechanism 5 cooperates to drive the film pusher seat to move.

[0068] Preferably, the film pusher assembly drives the carrier to move from the initial position to the working position for film pushing, and then moves back to the initial position after completion; the carrier is placed in the body 1 and the material is unloaded from the body 1 at the initial position.

[0069] Preferably, the film pushing seat assembly drives the carrier to move from the initial position to the working position for film pushing, and then moves back to the initial position after completion. The main body 1 is placed in and the material is unloaded from the main body 1 at the initial position. The operator places the carrier that needs to be pushed at the initial position, and removes the carrier that has been pushed from the initial position. The operator's operating position is fixed, which is convenient for operation and also convenient for the arrangement of instruments and equipment.

[0070] For example, the following specific structure can be adopted: the film pusher seat driving mechanism 5 specifically includes a base plate 51, a film pusher power source 52, a film pusher transmission member 53, a film pusher guide rail 54 and a film pusher slider 55. The film pusher guide rail 54 is fixed to the base plate 51 to limit the moving direction; the film pusher slider 55 is slidably connected to the film pusher guide rail 54 and connected to the film pusher transmission member 53, and receives the power of the film pusher transmission member 53 to slide on the film pusher guide rail 54; the body 1 is fixedly connected to the film pusher slider 55, and the power of the film pusher power source 52 is transmitted to the film pusher slider 55 by the film pusher transmission member 53, driving the body 1 to move. The film pusher head assembly 4 is arranged on the side of the film pusher guide rail 54. After the body 1 moves from the initial position to the working position of the film pusher head assembly 4 to push the film, it moves back to the initial position for unloading.

[0071] Preferably, the push-piece transmission member 53 is a screw rod fixedly connected to the power output end of the push-piece power source 52; the push-piece slider 55 cooperates with the screw thread, and the push-piece slider 55 is driven by the screw rod to move, and the moving distance is more controllable, and it can stop accurately at the target position.

[0072] Preferably, one end of the film pushing guide rail 54 exceeds the film pushing head assembly 4, that is, the initial position of the film pushing guide rail 54 exceeds the shell of the film pushing head assembly 4 to avoid interference between the film pushing head assembly 4 and the operation of taking and placing the carrier.

[0073] A semi-automatic analyzer comprises the film pushing mechanism described in any one of the above items.

[0074] The present application also provides a semi-automatic analyzer, comprising any of the above-mentioned film pushing mechanisms, to achieve fast and stable taking and placing of the carrier.

[0075] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
