Description
Technical Field
[0001] This utility model relates to the field of testing equipment technology, and in particular to a tin foil adding device. Background Technology
[0002] With the advancement of intelligent fuel analysis, the application scope of unmanned testing systems is constantly expanding. Taking the CHN elemental analyzer as an example, this instrument uses tin foil to wrap the sample to be tested and determines the content of elements such as C, H, and N in the sample by detecting the gases produced after the sample is burned. To ensure accurate test results, the tin foil must completely wrap the sample without leakage, and as much air as possible must be squeezed out of the sample.
[0003] Currently, the process typically involves manually placing and pressing tin foil into a CHN tin foil cup holder. A robotic arm then picks up the CHN tin foil cup holder containing the tin foil and weighs a specific mass of coal sample using a weighing module. The sample is then automatically wrapped using a double lotus disc wrapping mechanism. However, manually adding and pressing the tin foil is inefficient, easily damages the tin foil, and suffers from issues such as misalignment and inconsistent pressing quality. Utility Model Content

The feeding assembly is used to feed foil to the suction assembly, and the suction assembly is used to pick up the foil and blow it into the foil cup holder.
[0006] As a further improvement to the above technical solution: The suction assembly includes a moving mechanism and a suction head. The moving mechanism is connected to the suction head to drive the suction head to move between the foil cup holder and the paper feeding assembly.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0029] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.
[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0032] Example 1: like Figures 1 to 7 As shown, the foil feeding device of this embodiment includes a frame 1, on which a foil cup holder 2, a paper feeding component 3 and a suction component 4 are provided. The paper feeding component 3 is used to feed foil to the suction component 4, and the suction component 4 is used to pick up the foil and blow it into the foil cup holder 2.
[0033] In this embodiment, the tin foil adding device operates by moving the suction component 4 to the paper feeding component 3 and sucking in air. Under negative pressure, the tin foil is adsorbed onto the suction component 4 and pressed into a tin foil cup. Then, the suction component 4 moves to the tin foil cup holder 2 and blows air into the cup. Under positive pressure, the tin foil cup separates from the suction component 4. The suction component 4 then moves back to the paper feeding component 3, and the tin foil cup is pressed into the tin foil cup holder 2, allowing for subsequent sample weighing and packaging.
[0034] In this embodiment, the tin foil adding device uses suction and blowing to pick up and separate the tin foil, achieving reliable gripping, handling and separation of the tin foil. The force applied to the tin foil is controllable, avoiding damage to the tin foil. It can also automatically add tin foil, improving the automation level of the unmanned testing system and increasing work efficiency.
[0035] Furthermore, in this embodiment, the suction assembly 4 includes a moving mechanism 41 and a suction head 42. The moving mechanism 41 is connected to the suction head 42 to drive the suction head 42 to move between the foil cup holder 2 and the paper supply assembly 3. The bottom of the suction head 42 is provided with a forming part 424 for forming the foil into a foil cup. By connecting the moving mechanism 41 to the suction head 42, the suction head 42 can be driven to move between the foil cup holder 2 and the paper supply assembly 3 to add foil. The structure is simple and reliable. The forming part 424 serves as an inner mold for forming the foil. When the suction head 42 picks up the foil, the foil can be bonded to the forming part 424 to form a foil cup, resulting in high molding quality and consistency. Preferably, in this embodiment, the forming part 424 is mushroom-shaped.
[0036] Preferably, in this embodiment, the moving mechanism 41 includes a rotary cylinder 411 and a lifting cylinder 412. The rotary cylinder 411 drives the suction head 42 to rotate horizontally, and the lifting cylinder 412 drives the suction head 42 to move vertically, thereby transferring the suction head 42 between the foil cup holder 2 and the paper feeding assembly 3. Of course, in other embodiments, the rotary cylinder 411 can also be implemented using an electric rotary table, and the lifting cylinder 412 can also be implemented using an electric push rod or a module.
[0037] Furthermore, in this embodiment, the suction head 42 is provided with a first air port 421 and multiple second air ports 422. The first air port 421 and the second air ports 422 are connected, and the second air ports 422 are located at the bottom of the suction head 42. When the suction head 42 draws air, the tin foil is adsorbed onto the bottom of the suction head 42 under negative pressure. When the suction head 42 blows air, the tin foil is separated from the suction head 42 under positive pressure and pressed into the tin foil cup holder 2. Moreover, since there are multiple second air ports 422, the tin foil can be subjected to uniform force, improving the molding quality of the tin foil. It also makes the contact between the tin foil and the suction head 42 more stable during adsorption and blowing, reducing problems such as tin foil breakage or displacement caused by uneven local force.
[0038] Furthermore, in this embodiment, a quick-connect connector interface 423 is provided at the first air port 421. The quick-connect connector interface 423 facilitates connection with an external air source or air extraction device, enabling rapid air exchange and maintenance.
[0039] Furthermore, in this embodiment, the bottom of the suction head 42 is made of a soft material, such as rubber, to avoid damaging the tin foil.
[0040] Furthermore, in this embodiment, the paper feeding assembly 3 includes a foil tube 31 located on one side of the foil cup holder 2, and the foil tube 31 contains a foil stack 32 formed by stacking multiple sheets of foil. By adopting the paper feeding method of the foil stack 32, it is convenient to store and provide foil. When foil needs to be added, it can be drawn from the foil stack 32. The structure is simple and the operation is convenient.
[0041] Furthermore, in this embodiment, the foil stack 32 is made of circular foil. Of course, in other embodiments, the foil stack 32 can also be made of square or other shapes.
[0042] Furthermore, in this embodiment, the frame 1 is also provided with a clamping assembly 5 for clamping the foil cup holder 2. The clamping assembly 5 can ensure that the foil cup holder 2 is fixed in position during operation and will not move or shake, thereby ensuring that the foil can be accurately pressed into the foil cup holder 2.
[0043] Furthermore, in this embodiment, the clamping assembly 5 includes a clamping cylinder 51 and a gripper 52. The clamping cylinder 51 is connected to the gripper 52 to drive the gripper 52 to clamp or release the foil cup holder 2. When it is necessary to place or remove the foil cup holder 2, the clamping cylinder 51 drives the gripper 52 to release; when foil is added and pressed, the clamping cylinder 51 drives the gripper 52 to clamp the foil cup holder 2 to ensure its stability.
[0044] The specific working process of the tin foil adding device in this embodiment is as follows: First, the gripper 52 clamps the aluminum foil cup holder 2 and corrects its position. The suction head 42 descends onto the aluminum foil stack 32, and the air pump connected to the suction head 42 is activated to draw air. Under negative pressure, the aluminum foil adheres to the suction head 42. Due to the curved shape of the suction head 42, the aluminum foil is automatically separated from the aluminum foil stack 32. The lifting cylinder 412 rises to its upper limit, and then the rotating cylinder 411 drives the suction head 42 to rotate directly above the aluminum foil cup holder 2. The lowering cylinder 412 descends to the foil cup holder 2, keeping the foil tightly pressed and shaped into a foil cup; the air pump connected to the suction head 42 is started to blow air, and under the action of positive pressure, the foil cup separates from the suction head 42, while the foil cup is pressed tightly on the foil cup holder 2; the suction head 42 rises to the upper limit position, and the rotating cylinder 411 drives the suction head 42 to rotate directly above the foil tube 31, and the gripper 52 releases the foil cup holder 2, so that the subsequent sample weighing and packaging can be carried out.
[0045] Example 2: Figures 5 to 7Another embodiment of the present invention is shown. The difference between the foil feeding device in this embodiment and that in the first embodiment is that the paper feeding assembly 3 includes a stamping plate 33, a drive roller 34, and a driven roller (not shown in the figure). A foil roll 36 is mounted on the driven roller. Guide rollers 35 are provided on both sides of the stamping plate 33 to guide the foil roll 36. The drive roller 34 is used to drive the foil roll 36 to be transported to the drive roller 34 after passing around the stamping plate 33. A cutting blade 43 for cutting the foil roll is provided on the outside of the suction head 42. Driven by the drive roller 34, the foil roll 36 is continuously conveyed forward. When the suction head 42 moves to the stamping plate 33 to pick up the foil, the cutting blade 43 can simultaneously cut the foil roll 36 to cut the foil of the appropriate size so that the suction head 42 can pick it up. By using the paper feeding method of cutting with the cutting blade 43, deformation when multiple foil sheets are stacked can be avoided, as well as foil clamping during suction, resulting in high suction reliability.
[0046] Furthermore, in this embodiment, the cutting edge of the punching knife 43 is flush with the bottom of the suction head 42, which makes the size of the punched tin foil more accurate and matches the suction position of the suction head 42, thereby improving the accuracy and stability of suction.
[0047] The specific working process of the tin foil adding device in this embodiment is as follows: First, the gripper 52 clamps the aluminum foil cup holder 2 and corrects its position. The suction head 42 descends onto the unfolded aluminum foil roll 36, and the cutting blade 43 cuts the aluminum foil roll 36 into the set shape. The air pump connected to the suction head 42 is started to suck in air. Under the action of negative pressure, the aluminum foil is adsorbed onto the suction head 42. Since the suction head 42 has a curved arc, the aluminum foil is automatically separated from the aluminum foil roll 36. The lifting cylinder 412 rises to the upper limit, and then the rotating cylinder 411 rotates to drive the suction head 42 to directly above the aluminum foil cup holder 2. The lifting cylinder descends to the foil cup holder 2, keeping the foil paper pressed and shaped into a foil cup; the air pump connected to the suction head 42 is started to blow air, and under the action of positive pressure, the foil cup separates from the suction head 42, while the foil cup is pressed tightly on the foil cup holder 2; the suction head 42 rises to the upper limit, the rotary cylinder 411 drives the suction head 42 to rotate, the gripper 52 releases the foil cup holder 2, and subsequent sample weighing and packaging can be carried out. At the same time, the drive roller 34 drives the foil roll to rotate a specified distance to prepare for placing the next foil cup.
