Description

Technical Field

[0001] This utility model mainly relates to the field of sample testing technology, and specifically refers to a crucible transfer device. Background Technology

[0002] In the coal quality analysis industry, automated testing equipment is used to test the ash content, volatile matter, sulfur content, and calorific value of coal. This requires calorific value crucibles, ash crucibles, volatile matter crucibles, and sulfur crucibles, involving operations such as crucible transfer and handling. In intelligent sample testing systems, crucibles are typically placed on crucible holders, which are moved between different workstations by a drive mechanism. A robotic arm then delivers the crucibles to different analytical devices for testing various indicators. In existing technologies, gaps exist between the crucible holder and the crucible, leading to several problems: 1. Inconsistent crucible positions affect the reliability of subsequent processes. For example, when the robotic arm grips a crucible, inconsistent positions may cause unstable gripping, resulting in the crucible falling; 2. Insufficient crucible fixation poses a risk of dropping during acceleration, deceleration, or jamming of the transfer component's cylinder, leading to sample spillage or even system malfunction, affecting the operation of the entire intelligent testing system. Ensuring stable and reliable crucible transfer in intelligent testing systems is a technical problem urgently needing to be solved by those skilled in the art. Utility Model Content

[0003] To address the technical problems existing in the prior art, this utility model provides a crucible transfer device that can achieve precise positioning and stable and reliable transfer of the crucible.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A crucible transfer device includes a crucible pick-and-place platform, a translation drive assembly, and a crucible positioning assembly. The crucible pick-and-place platform is connected to the translation drive assembly via a bracket. The crucible pick-and-place platform includes a base plate and an outer wall. The outer wall is located at the outer edge of the base plate and has a notch or through hole. The crucible positioning assembly passes through the notch or through hole in the outer wall and holds the crucible against it so that the crucible is in close contact with the outer wall of the crucible pick-and-place platform during the transfer process.

[0006] As a further improvement of this utility model: the translation drive assembly includes a control valve, a drive cylinder and a cable chain assembly. The control valve controls the opening and closing of the drive cylinder, the drive cylinder drives the cable chain assembly to move, and one end of the cable chain assembly is connected to the bracket.

[0007] As a further improvement of this utility model: the cable chain assembly includes a cable chain bracket and a cable chain.

[0008] As a further improvement of this utility model: the crucible positioning component is a telescopic component.

[0009] As a further improvement of this utility model: the telescopic component is a telescopic cylinder or a drive component and a push rod.

[0010] As a further improvement of this utility model: crucible detection components are symmetrically provided on both sides of the crucible placement and removal platform, and the crucible detection components are used to detect whether there is a crucible on the crucible transfer platform.

[0011] As a further improvement of this utility model, the crucible detection component is a photoelectric detector.

[0012] As a further improvement of this utility model: the outer wall of the crucible handling platform is provided with slots for photoelectric detectors to shoot through.

[0013] As a further improvement of this utility model: the bracket includes a connecting base plate, a first connecting rod and a second connecting rod, the first connecting rod being perpendicularly connected to the connecting base plate, the second connecting rod being parallel to the connecting base plate, one end of the second connecting rod being connected to the connecting base plate, and the other end being connected to the crucible placement platform.

[0014] As a further improvement of this utility model, the bracket also includes a support plate for supporting the crucible positioning assembly, and the crucible positioning assembly is mounted on the support plate.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] This invention relates to a crucible transfer device, which innovatively incorporates a crucible positioning component. By precisely creating notches or through holes on the outer wall of the crucible placement platform, the positioning component can effectively pass through, ensuring that the crucible is tightly pressed against the front end of the platform before each transfer. This achieves precise positioning of the crucible. Throughout the entire crucible movement process, the positioning component continuously functions, firmly pressing the crucible. Even when the translation drive component starts, stops, or experiences instability such as jamming, the crucible remains firmly held on the platform, preventing it from falling. This not only ensures stable and reliable crucible transfer, effectively preventing system malfunctions caused by crucible drops, but also significantly improves the overall reliability of the intelligent testing system.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1 to 2 As shown, this embodiment discloses a crucible transfer device, including a crucible pick-and-place platform 1, a translation drive assembly, and a crucible positioning assembly 3. The crucible pick-and-place platform 1 is connected to the translation drive assembly via a bracket 4. The crucible pick-and-place platform 1 includes a base plate 11 and an outer wall 12. The outer wall 12 is located at the outer edge of the base plate 11 and has a notch or through hole. The crucible positioning assembly 3 passes through the notch or through hole on the outer wall 12 and holds the crucible against it so that the crucible is in close contact with the outer wall 12 of the crucible pick-and-place platform 1 during the transfer process.

[0027] The crucible transfer device in this embodiment innovatively incorporates a crucible positioning component 3. By precisely creating notches or through holes in the outer wall 12 of the crucible loading / unloading platform 1, the positioning component 3 can effectively pass through, ensuring that the crucible is reliably pressed against the front end of the platform 1 before each transfer. This achieves precise positioning of the crucible, ensuring accurate loading and unloading by the robotic arm. Throughout the crucible movement, the positioning component 3 continuously functions, firmly pressing the crucible. Even when the translation drive component starts, stops, or experiences instability such as jamming, the crucible remains firmly held on the platform 1, preventing it from falling. This not only ensures stable and reliable crucible transfer, effectively preventing system malfunctions caused by crucible drops, but also significantly improves the overall reliability of the intelligent testing system.

[0028] In this embodiment, the translation drive assembly includes a control valve 21, a drive cylinder 22, and a cable chain assembly 23. The control valve 21 controls the opening and closing of the drive cylinder 22, and the drive cylinder 22 drives the cable chain assembly 23 to move. One end of the cable chain assembly 23 is connected to the bracket 4.

[0029] In this embodiment, the cable chain assembly 23 includes a cable chain bracket 231 and a cable chain 232. The drive cylinder 22 drives the cable chain bracket 231 and the cable chain 232 to move, thereby driving the bracket 4 and the crucible loading and unloading platform 1 to move left and right to realize the transfer of the crucible between different workstations.

[0030] In this embodiment, the crucible positioning component 3 is a telescopic component. Further, in a preferred embodiment, the telescopic component is a telescopic cylinder. In other embodiments, the crucible positioning component 3 can also be designed as a combination of a push rod and a driving component, with the driving component driving the push rod to extend and retract, pressing the crucible firmly against the outer wall 12 of the crucible placement platform 1 during crucible transfer, ensuring that the crucible does not fall.

[0031] In this embodiment, crucible detection components 5 are symmetrically arranged on both sides of the crucible placement platform 1. The crucible detection components 5 are used to detect whether a crucible is present on the crucible placement platform 1. Further, in a preferred embodiment, the crucible detection component 5 is a photoelectric detector. It should be noted that in other embodiments, the crucible detection component 5 can also be other detectors, such as a proximity switch sensor.

[0032] In this embodiment, the support 4 includes a connecting base plate 41, a first connecting rod 42, and a second connecting rod 43. The first connecting rod 42 is perpendicularly connected to the connecting base plate 41, and the second connecting rod 43 is parallel to the connecting base plate 41. One end of the second connecting rod 43 is connected to the connecting base plate 41, and the other end is connected to the crucible placement platform 1. The support 4 also includes a support plate 44 for supporting the crucible positioning assembly 3, which is mounted on the support plate 44. Further, in a preferred embodiment, the support plate 44 has a groove, and the crucible positioning assembly 3 is disposed in the groove.

[0033] Example 2

[0034] like Figure 3 As shown, this embodiment is basically the same as Embodiment 1, except that the outer wall 12 of the crucible placement platform 1 is designed to be taller, which greatly improves the capacity to accommodate and protect tall crucibles. This design effectively increases the stability of the crucible during the placement process, fundamentally reducing the risk of the crucible being overturned due to accidental collisions, equipment vibrations, or improper operation.

[0035] To ensure accurate detection of the crucible's status even when using tall crucibles, slots 121 for photoelectric detectors are provided on the outer wall 12 of the crucible handling platform 1. This design allows the photoelectric detector to accurately sense the crucible's position, presence, and dynamic status during handling. When the crucible is correctly placed on the platform, the light path is blocked, and the system receives a normal signal in real time, confirming that the crucible is in a safe and stable position. If the crucible shifts, tilts, or is mistakenly removed, the photoelectric detector quickly feeds back the signal change to the control system, triggering the corresponding alarm device. This promptly alerts the operator to inspect and handle the situation, enhancing the safety and controllability of the entire intelligent testing system, reducing downtime caused by crucible drops or tipping, and improving system efficiency.

[0036] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should be considered within its protection scope.
