Description

Technical Field

[0001] The present application relates to the technical field of heating equipment, and in particular to a mold fixing mechanism and a mold cooling device for an automated melting sample equipment. Background Art

[0002] The glass frit method involves mixing a processed powder sample and a flux in a specific weight and ratio (a release agent is also added to facilitate demolding). The mixture is then placed in a crucible, which is then heated in a melting machine to melt the sample. The molten liquid is then poured into a mold and allowed to cool, resulting in a glass frit. In X-ray fluorescence spectrometry, this method can effectively reduce or even eliminate adverse factors such as particle effects, matrix effects, and mineral effects, significantly improving the accuracy of X-ray fluorescence analysis.

[0003] When using automated equipment to prepare glass frits, a handling mechanism (such as a robot) places the mold containing the molten sample into a mold cooling device for cooling. After cooling, a suction cup is used to remove the glass frit from the mold and place it on a designated glass frit tray for subsequent X-ray fluorescence spectrometry analysis. However, existing mold cooling devices sometimes remove the mold along with the glass frit due to improper demolding. Utility Model Content

[0031] like Figures 1 to 6 As shown, the embodiment of the present invention provides a mold fixing mechanism for switching the mold 1 between a fixed state and a non-fixed state. In this embodiment, there are multiple molds 1, forming M groups arranged along the first direction, and each group includes N molds arranged along the second direction. Figure 1 As shown, M=4, N=2.

[0032] The mold fixing mechanism includes a first baffle 2, a second baffle 3, two pairs of opening and closing mechanisms, and a driving module.

[0033] The first baffle 2 and the second baffle 3 are located above the mold 1 and along the first direction (i.e. Figure 5 In this embodiment, there are M pairs of first and second baffles 2 and 3, each corresponding to a set of molds 1 and located on either side of the set. The first and second baffles 2 and 3 are provided with arcuate grooves 21 and 31 on their inner sides that correspond to the mold contours, thereby shortening the travel of the first and second baffles 2 and 3.

[0034] The two pairs of opening and closing mechanisms are respectively located at the mold along the second direction (i.e. Figure 5The first and second directions are both horizontal and perpendicular to each other. Each pair of opening and closing mechanisms includes a first opening and closing member 41 and a second opening and closing member 42. The two first opening and closing members 41 connect all the first baffles 2, and the two second opening and closing members 42 connect all the second baffles 3.

[0035] The driving module is connected to the two pairs of opening and closing mechanisms to respectively drive the first opening and closing member 41 and the second opening and closing member 42 to respectively drive the first baffle 2 and the second baffle 3 to move relative to or opposite to each other along the first direction; after the relative movement is completed, the first baffle 2 and the second baffle 3 are in a closed state, blocking the edge of the mold from above, so that the mold is in a fixed state (such as Figure 3 、 Figure 4 After the back-to-back movement is completed, the first baffle 2 and the second baffle 3 are in an open state, and the edge of the mold is no longer blocked by the first baffle 2 and the second baffle 3, so that the mold is in a non-fixed state (such as Figure 1 、 Figure 2 ).

[0036] In this embodiment, the driving module includes a linear driving mechanism (such as an electric push rod, a linear cylinder, etc., not shown), and a different direction translation motion conversion mechanism. The different direction translation motion conversion mechanism connects the linear driving mechanism and the two pairs of opening and closing mechanisms. The linear driving mechanism drives the different direction translation motion conversion mechanism along the second direction, and the different direction translation motion conversion mechanism converts the two pairs of opening and closing mechanisms to move along the first direction.

[0037] Specifically, in this embodiment, the mechanism for converting translational motion in different directions includes a first cam plate 51, two first base plates 52, and a first roller 53. The first cam plate 51 is connected to the linear drive mechanism and can only perform linear motion in the second direction. Its upper surface is provided with pairs of first grooves 511 (two pairs of first grooves in this embodiment) arranged along the second direction. The distance between the two first grooves in each pair of first grooves increases gradually from one end (the first end) to the other end (the second end) (i.e., forming a figure eight). The two first base plates 52 are arranged along the first direction, with their ends connected to the first opening and closing member 41 and the second opening and closing member 42, respectively (i.e., one first base plate 52 is connected to the first opening and closing member 41, and the other first base plate 52 is connected to the second opening and closing member 42). A first roller 53 is installed in the middle of each first base plate 52 (in this embodiment, two first rollers 53 are installed in the middle of each first base plate 52, which makes the operation more stable). Each first roller 53 is installed in a first groove 511, so that the first cam plate 51 is driven by the linear drive mechanism to perform linear motion along the second direction. The first groove 511 drives the corresponding first roller 53 to move. Since the distance between the two first grooves 511 along the first direction gradually increases from one end (first end) to the other end (second end), the first base plate 52 is further driven to perform linear motion along the first direction.

[0038] Specifically, if Figure 5 As shown, the first baffle 2 and the second baffle 3 are currently in an open state. When the first cam plate 51 moves along the "Y-" direction, the first roller 53 moves from the end with a larger distance to the end with a smaller distance, and the first opening and closing member 41 and the second opening and closing member 42 respectively drive the first baffle 2 and the second baffle 3 to move relative to each other along the first direction (that is, the first opening and closing plate moves toward the "X+" direction, driving the second opening and closing plate to move toward the "X-" direction), so that the first baffle 2 and the second baffle 3 are converted from the open state to the closed state. On the contrary, when the first baffle 2 and the second baffle 3 are in the closed state, the first cam plate 51 moves along the "Y+" direction, and the first roller 53 moves from the end with the smaller distance (the first end) to the end with the larger distance (the second end). The first opening and closing member 41 and the second opening and closing member 42 respectively drive the first baffle 2 and the second baffle 3 to move in opposite directions along the first direction (that is, the first opening and closing plate moves in the "X-" direction, driving the second opening and closing plate to move in the "X+" direction), so that the first baffle 2 and the second baffle 3 are converted from the closed state to the open state.

[0039] In this embodiment, both the first cam plate 51 and the opening and closing mechanism are constrained to linear motion in one direction via the optical axis 6 (of course, other mechanisms, such as guide rail and slider mechanisms, may be employed in other embodiments). The first cam plate 51 is provided with a protrusion 512 extending along a first direction. The mold fixing mechanism is provided with stoppers 7 on either side of the protrusion 512 along a second direction. These stoppers 7 are used to detect whether the first baffle 2 and the second baffle 3 are in the closed or open state, i.e., whether the mold 1 is in the unfixed or fixed state, by abutting the protrusions 512, thereby improving operational reliability.

[0040] Of course, in other embodiments, the different-direction translational motion conversion mechanism may also adopt other structures, as long as it can convert the translational motion in one direction into the translational motion in another direction.

[0041] In other embodiments, the drive module may also adopt other structures. Figure 7 、 Figure 8 As shown, the driving module includes a rotational driving mechanism (such as a motor, not shown) and a rotational-to-translational motion conversion mechanism. The rotational-to-translational motion conversion mechanism connects the rotational driving mechanism and the two pairs of opening and closing mechanisms. The rotational driving mechanism drives the rotational-to-translational motion conversion mechanism to rotate, and the rotational-to-translational motion conversion mechanism converts the two pairs of opening and closing mechanisms to move along a first direction.

[0042] Specifically, in this embodiment, the rotation-to-translation motion conversion mechanism includes a second cam plate 51', two second base plates 52', and a second roller 53'. The second cam plate 51' is connected to the rotation drive mechanism, and its upper surface is provided with a second groove 511'. The groove of the second groove 511' is annular, and the distance between the two grooves in one direction (the long axis direction) is greater than the distance between the two grooves in the other direction (the short axis direction). The two second base plates 52' are arranged along the first direction, and their ends are respectively connected to the first opening and closing member 41 and the second opening and closing member 42. A second roller 53' is installed in the middle of each second base plate 52', and each second roller 53' is installed in the second groove 511'. The second cam plate 51' is driven by the rotary drive mechanism to rotate, and the second groove 511' is used to drive the second roller 53' to move, further driving the second base plate 52' to perform linear motion along the first direction. When the second roller 53' moves from the groove with a smaller distance (in the direction of the short axis) to the groove with a larger distance (in the direction of the long axis), the first opening and closing member 41 and the second opening and closing member 42 respectively drive the first baffle 2 and the second baffle 3 to move in opposite directions along the first direction; and when moving from the groove with a larger distance (in the direction of the long axis) to the groove with a smaller distance (in the direction of the short axis), the first opening and closing member 41 and the second opening and closing member 42 respectively drive the first baffle 2 and the second baffle 3 to move relative to each other along the first direction.

[0043] Of course, in other embodiments, the rotation-to-translation motion conversion mechanism may also adopt other structures, as long as it can convert rotational motion into translational motion.

[0044] like Figures 1 to 4 As shown, this embodiment also provides a mold cooling device, including a cooling bracket 8 and a mold fixing mechanism. The cooling bracket 8 is used to place the mold 1, and the mold fixing mechanism is used to switch the mold 1 between a fixed state and a non-fixed state, which is the mold fixing mechanism described above.

[0045] In this embodiment, there are multiple mold holders 8, forming M groups arranged along the first direction. Each group includes N mold holders arranged along the second direction, allowing for simultaneous placement of M*N molds and cooling of these molds. There are M pairs of first baffles 2 and second baffles 3, each corresponding to a group of molds 1 and positioned on either side of that group. First and second opening and closing members 41, 42 are positioned on either side of the molds along the second direction, connecting all first and second baffles 2 and 3.

[0046] The operation process is described as follows. Figure 1 、 Figure 2 As shown, the mold fixing mechanism is in the open state (first baffle 2 and second baffle 3), and the crucible placement position of the cooling bracket 8 is not blocked by the baffle. The transport mechanism (such as a robot) drives the clamping claw 91 to place the mold 1 (containing the high-temperature glass melt 11) into the cooling bracket 8. Figure 3 、 Figure 4 As shown, after mold 1 has cooled, the mold securing mechanism closes (first baffle 2 and second baffle 3 move closer together), securing the mold edge. The transport mechanism then drives suction cup 92 to absorb the glass melt 11 within mold 1. Because the mold edge is secured, mold 1 is prevented from being pulled out.

[0047] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one 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 is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
