Description

Technical Field

[0001] The utility model belongs to the technical field of automated mechanical equipment, and in particular relates to an upper cover device. Background Art

[0002] Fire assay refers to a method of determining the content of precious metal components in minerals and metal products by melting and roasting. Since precious metals often exist in minerals in an irregularly dispersed state, a large amount of minerals is often required to extract a representative sample and crush the sample. Before melting the sample, the crushed sample is placed in a crucible, and an appropriate flux (such as crushed sodium carbonate, borax, silicate, lead oxide, etc.) is added to the crucible and mixed evenly with the sample.

[0003] At present, in the automated operation of fire assay, the mixing process is generally to flip and / or shake the crucible through a corresponding mechanism to mix the sample and flux in the crucible evenly. In order to prevent the sample and flux from spilling during the mixing process, the top of the crucible needs to be sealed before the mixing process.

[0004] Some existing technologies seal the crucible by setting a movable cover to press on the top of the crucible, and remove the cover from the top of the crucible after mixing. However, during the process of turning and / or shaking the crucible, the sample and flux will adhere to the cover in an uncertain amount, which may easily have a certain impact on the final test results.

[0005] If a disposable flammable lid is added to the top of each crucible before mixing, and the lid is used to seal the top of the crucible, the lid will follow the corresponding crucible into the furnace for combustion. This method can effectively ensure that the sample and flux content in the crucible will not change after mixing, reducing the impact on the experimental results. However, in actual automated operations, if the transfer mechanism drives the picking mechanism to move downward and pick up the top lid of the stacked lids in turn to seal the top of each crucible, since adjacent lids are easily adhered in the stacked state, and the gaps between adjacent lids are difficult to accurately control, it is difficult to accurately control the picking mechanism to accurately contact the top lid each time and pick up only one lid through the stroke setting of the transfer mechanism, and it is difficult to accurately control the downward pressure of the picking mechanism each time it contacts the top lid. If the picking mechanism does not contact the top lid when moving downward, it will not be able to pick up the lid, resulting in failure to normally close the top of the crucible. If the picking mechanism moves downward too much, the stacked lids will be pressed tighter, resulting in the inability to pick up the lids later or picking up multiple lids at a time, resulting in the inability to properly close the top of the crucible or the lids on the top of the crucible being stacked too high, affecting the normal progress of other subsequent processes. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a cover device which ensures that the picking mechanism can accurately contact the top cover each time the cover is picked up and the downward pressure of the picking mechanism is consistent each time the picking mechanism contacts the top cover, and can more easily and accurately pick up a cover at a time, thereby improving the stability and reliability of the cover operation.

[0007] The content of this utility model includes:

[0009] A detection mechanism, used for detecting whether the topmost cover among a plurality of stacked covers is at a target height;

[0010] A lifting mechanism, wherein the lifting portion of the lifting mechanism is located below the stacked lids, and the lifting mechanism is used to push the stacked lids toward the lid outlet and stop according to the detection signal of the detection mechanism;

[0011] A lid distributing mechanism, the lid distributing mechanism comprising a material distributing fork, the material distributing fork being movable parallel to the lid outlet and extending between the opening end of the top lid among the stacked lids and the opening end of the lid below it;

[0012] A picking mechanism and a transfer mechanism, wherein the transfer mechanism is used to drive the picking mechanism to move toward the cover outlet to pick up the top cover among the covers, and is used to drive the picking mechanism to move toward the top of the crucible.

[0013] Furthermore, it also includes a power mechanism, wherein there are more than two storage cover cavities on the storage cover mechanism, and the more than two storage cover cavities are at the same height on the storage cover mechanism, and the power mechanism is used to drive the storage cover mechanism and the lifting mechanism to move or rotate relative to each other, so that the lifting part of the lifting mechanism is located below several covers stacked in different storage cover cavities.

[0014] Furthermore, the power mechanism is used to drive the storage cover mechanism to move or rotate so that the storage cover mechanism and the lifting part of the lifting mechanism move or rotate relative to each other. The number of the separation mechanism and the detection mechanism are both one, both are arranged outside the storage cover mechanism and do not rotate or move with the storage cover mechanism.

[0015] Furthermore, it also includes a pressing plate, which is located above the storage cover mechanism. When the storage cover mechanism moves or rotates, the cover outlets on the tops of the two or more storage cover cavities pass along the bottom of the pressing plate in sequence.

[0016] Furthermore, the power mechanism is a rotary drive mechanism for driving the storage cover mechanism to rotate, and the two or more storage cover cavities are circumferentially arranged on the storage cover mechanism around the rotation axis of the storage cover mechanism.

[0017] Furthermore, the power mechanism is a linear drive mechanism for driving the storage cover mechanism to move linearly, and the two or more storage cover cavities are arranged on the storage cover mechanism at intervals along the linear movement direction of the storage cover mechanism.

[0018] Furthermore, the lifting mechanism includes a lifting module and a support plate, the support plate is arranged on the output end of the lifting module to form a lifting part of the lifting mechanism, the lifting module is located on the side of the storage cover mechanism, and the storage cover mechanism is located on the side of the storage cover cavity and is provided with a movable groove for the support plate to move along the height direction of the storage cover cavity.

[0019] Furthermore, when there are more than two storage cover cavities, the storage cover mechanism is provided with an opening at the bottom of each storage cover cavity for the support plate to pass through, the opening is connected to the movable groove, and the width of the opening is smaller than the width or diameter of a single cover.

[0020] Furthermore, the storage cover mechanism includes an upper support plate, a lower support plate and a rod body assembly, the rod body assembly is arranged between the upper support plate and the lower support plate, and the number of the rod body assembly corresponds to the number of storage cover cavities, a single rod body assembly includes more than three limiting rods, one end of the more than three limiting rods is connected to the upper support plate, and the other end is connected to the lower support plate, the storage cover cavity is formed between the more than three limiting rods, and the movable groove is formed between two adjacent limiting rods, the cover outlet is arranged on the upper support plate, and the opening is arranged on the lower support plate.

[0021] Furthermore, the picking mechanism is a vacuum suction cup.

[0022] The beneficial effect of the utility model is that, through the arrangement of the detection mechanism, the lifting mechanism and the cover separating mechanism, when several covers are in a stacked state, the lifting mechanism lifts the stacked covers upward from the bottom. In this process, through the arrangement of the detection mechanism, it is detected whether the top cover among the stacked covers has reached the target height. After reaching the target height, the lifting mechanism stops, and the material separating fork limits the cover below the top cover in the cover stacking height direction to avoid the cover below from sticking when the top cover is taken out.

[0023] In the case where the number of stacked lids is different and the natural stacking gap is inconsistent, it can be ensured that the position of the top lid among the stacked lids remains consistent each time the lid is picked up, so that the operation of picking up the lid is not affected by the number of stacked lids and the gap, and the top lid will not stick to the lid below it due to the limiting blocking effect of the material distribution fork during the process of picking up the lid. Therefore, it can be ensured that the picking mechanism can accurately contact the top lid each time the lid is picked up and that the downward pressure of the picking mechanism is consistent each time when the lid is picked up, so that the lids can be prevented from being pressed too tightly due to excessive downward pressure when the picking mechanism contacts the top lid. On the one hand, it can ensure that the gap between several stacked lids is not too small, thereby ensuring that the dispensing fork can accurately extend to the side of the top lid and be located on the top of the lower lid; on the other hand, the top lid can be easily removed without increasing the force exerted on the lid by the picking mechanism when picking up, which can effectively avoid the problem of lid breakage caused by excessive picking force, thereby ensuring the improvement of the operational reliability of automated lid picking, ensuring that the picking mechanism can accurately pick up a lid each time, improving the stability and reliability of the upper lid operation, reducing the travel control requirements and difficulty of the transfer mechanism, and ensuring that the top of the crucible is effectively closed by the lid as much as possible, and there will be no situation where too many lids stacked on the top of the crucible cause the overall top to be too high and affect other subsequent processes.

DETAILED DESCRIPTION

[0030] like Figure 1-Figure 5 As shown, the utility model provides a cover device, including a cover storage mechanism 1, a detection mechanism 2, a lifting mechanism 3, a cover separation mechanism 4, a picking mechanism 6 and a transfer mechanism 5. The cover storage mechanism 1 is provided with a cover storage cavity for placing a plurality of stacked covers 100, and the stacking method of the plurality of covers is to stack them in the same direction along the axial direction of the covers. The cover storage mechanism 1 is provided with a cover outlet 111 at the top of the cover storage cavity, and the cover outlet 111 is connected to the cover storage cavity for the covers to pass through. The detection mechanism 2 is used to detect whether the topmost cover among the stacked covers 100 is at a target height. The lifting mechanism 3, the lifting part of the lifting mechanism 3 is located below the stacked covers 100, and the lifting mechanism 3 is used to push the stacked covers 100 toward the cover outlet 111, and stop according to the detection signal of the detection mechanism 2, and stop pushing the stacked covers 100 according to the detection signal of the detection mechanism 2. The lid dispensing mechanism 4 includes a dispensing fork 41, which can move parallel to the lid outlet 111 and extend along the side of the stacked lids 100 to between the opening end of the top lid and the opening end of the bottom lid among the stacked lids 100. The top lid specifically refers to the first lid at the top of the stacked lids 100, and the opening end of the lid is the end of the lid that is in the shape of an opening 121. Figure 3 As shown, the stacked lids 100 are arranged with their open ends facing upward, and the material distribution fork 41 specifically extends along the side of the top lid to between the open end of the top lid and the open end of the lower lid. The picking mechanism 6 is used to pick up the lids, and the picking mechanism 6 is arranged at the output end of the transfer mechanism 5. The transfer mechanism 5 is used to drive the picking mechanism 6 to move toward the lid outlet 111 to pick up the top lid among the lids, and to drive the picking mechanism 6 to move above the crucible, press the picked lid on the top of the crucible, make the lid and the top of the crucible interference fit, seal the top of the crucible, and complete the cover operation on the top of the crucible. Since the lid will be sent into the furnace together with the crucible later, the lid can be made of a material with a combustion product close to the flux composition, such as a paper lid or a lid of other materials that meet the requirements.

[0031] By means of the arrangement of the detection mechanism 2, the lifting mechanism 3 and the cover separating mechanism 4, when several covers are in a stacked state, the lifting mechanism 3 lifts the stacked covers 100 upward from the bottom. In this process, the detection mechanism 2 is arranged to detect whether the top cover among the stacked covers 100 reaches the target height. After reaching the target height, the lifting mechanism 3 stops and the separating fork 41 extends in the cover stacking height direction to limit the cover below the top cover to avoid the cover below from sticking when the top cover is taken out.

[0032] Based on the above, the upper cover device provided by the utility model can ensure that the position of the top cover among the stacked covers 100 remains consistent each time the cover is picked up, even when the number of stacked covers 100 is different and the natural stacking gaps are inconsistent, so that the operation of picking up the cover is not affected by the number and gaps of the stacked covers, and in the process of picking up the cover, the top cover will not stick to the cover below it due to the limiting blocking effect of the dispensing fork 41. Therefore, when the stroke of the transfer mechanism 5 remains unchanged, it can be ensured that the picking mechanism 6 can accurately contact the topmost lid each time the lid is picked up, and the downward pressure of the picking mechanism 6 when contacting the topmost lid is consistent each time, so as to avoid excessive downward pressure when the picking mechanism 6 contacts the topmost lid, which may cause the lids to be pressed too tightly. On the one hand, it can be ensured that the gap between the stacked lids 100 is not too small, so as to ensure that the dividing fork 41 can accurately extend to the side of the topmost lid and be located on the top of the lower lid. On the other hand, the topmost lid can be easily removed without increasing the force applied to the lid by the picking mechanism 6 when picking up. When the hardness of the lid material is low, such as a paper lid, the problem of lid breakage caused by excessive picking force can be effectively avoided, thereby ensuring the improvement of the operational reliability of the automatic lid picking, ensuring that the picking mechanism 6 can accurately pick up a lid each time, improving the stability and reliability of the upper lid operation, reducing the stroke control requirements and difficulty of the transfer mechanism 5, and ensuring that the top of the crucible is effectively closed by the lid as much as possible, and there will not be too many lids stacked on the top of the crucible, resulting in the overall top being too high and affecting other subsequent processes. Among them, the force applied by the picking mechanism 6 to the cover when picking up is the force acting on the cover when taking out the cover. When the picking mechanism 6 is a clamping claw, the force is a clamping force. When the picking mechanism 6 is a vacuum suction cup, the force is a suction force.

[0033] In the present invention, the storage cover cavity is specifically arranged vertically on the storage cover mechanism 1, that is, the depth direction of the storage cover cavity is arranged along the plumb direction, and the stacking direction of the plurality of lids in the storage cover cavity is also arranged along the plumb direction, and the position where the storage cover mechanism 1 is provided with the cover opening 111 is the top of the storage cover mechanism 1. Compared with the storage cover cavity being arranged obliquely or horizontally, and the stacked plurality of lids 100 being arranged obliquely or horizontally in the storage cover cavity, the present invention can avoid the problem of relative inclination of individual or part of the lids in the storage cover cavity with other lids, and better ensure that when the picking mechanism 6 picks up, the posture of the lid at the top is accurate, and ensure that the picking mechanism 6 can effectively pick up the lid.

[0034] When the number of the storage cover cavity on the storage cover mechanism 1 is one, the storage cover mechanism 1 is fixed as a whole, that is, it will not move or rotate during operation.

[0035] In a preferred embodiment of the present invention, the storage cover mechanism 1 is provided with more than two storage cover cavities, and the heights of the two or more storage cover cavities on the storage cover mechanism 1 are the same. The present invention further includes a power mechanism 7, which is used to drive the storage cover mechanism 1 and the lifting mechanism 3 to move or rotate, so that the storage cover mechanism 1 and the lifting mechanism 3 move or rotate relative to each other, so that the lifting part of the lifting mechanism 3 is located below the several covers 100 stacked in different storage cover cavities, so that the lifting part of the lifting mechanism 3 pushes the several covers 100 stacked in different storage cover cavities to move toward the cover outlet 111. This embodiment can increase the storage cover capacity while keeping the overall height of the storage cover cavity unchanged, and at the same time, when picking up the covers from each storage cover cavity, the height of the topmost cover in the storage cover cavity is consistent, which will not increase the stroke control requirements and difficulty of the transfer mechanism 5. On the basis of a larger storage cover capacity, the overall height of the device will not be too high, which will reduce the degree of limitation on the application site, i.e., the space, and make it more convenient to manually add covers to the storage cover cavity.

[0036] In the above preferred embodiment, when the power mechanism 7 specifically drives the lifting mechanism 3 to move or rotate, in order to ensure that the multiple covers 100 stacked in each storage cover cavity can be detected and separated, the detection mechanism 2 and the cover separation mechanism 4 also need to be correspondingly set to be movable or rotatable, or each storage cover cavity is correspondingly provided with a detection mechanism 2 and a cover separation mechanism 4. Therefore, it is further preferred that the power mechanism 7 specifically drives the storage cover mechanism 1 to move or rotate, so as to achieve the relative movement or relative rotation of the storage cover mechanism 1 and the lifting part of the lifting mechanism 3. The number of the cover separation mechanism 4 and the detection mechanism 2 in this embodiment is one, and both are arranged outside the storage cover mechanism 1 and do not rotate or move with the storage cover mechanism 1. In this preferred arrangement, the positions of the detection mechanism 2, the lifting mechanism 3 and the cap separation mechanism 4 remain unchanged, and through the movement or rotation of the storage cover mechanism 1, the same detection mechanism 2, the lifting mechanism 3 and the cap separation mechanism 4 are suitable for corresponding operations of a plurality of covers 100 stacked in different storage cover cavities, which can reduce the arrangement of the drive structure and the linkage connection, or reduce the number of arrangements of the detection mechanism 2 and the cap separation mechanism 4, thereby reducing the overall structural complexity and cost of the device.

[0037] Among them, when there are more than two storage cover cavities, the number of cover outlets 111 can correspond one-to-one to the number of storage cover cavities, that is, a cover outlet 111 is set on the top of each storage cover cavity, or more than two storage cover cavities share one cover outlet 111. The diameter of the cover outlet 111 is relatively large and can cover the tops of more than two storage cover cavities. The specific setting method can be determined according to actual processing requirements and structural design or strength requirements, as long as the covers in each storage cover cavity can be taken out normally along the cover outlet 111.

[0038] The utility model further comprises a pressing plate 8, which is located above the cover storage mechanism 1 and does not move or rotate with the cover storage mechanism 1. When the cover storage mechanism 1 moves or rotates, the cover outlets 111 at the top of the two or more cover storage cavities pass along the bottom of the pressing plate 8 in sequence. The arrangement of the pressing plate 8 can play a height limit prompting role above the cover outlet 111, so as to avoid the situation that too many covers are manually added to the cover storage cavity, resulting in excessive height after stacking, causing the detection mechanism 2 to be mis-touched or inaccurately detected. Since the pressing plate 8 does not move or rotate with the cover storage mechanism 1, by arranging it at a place other than the position of the cover separation mechanism 4 and the transfer mechanism 5, it can play a height limit prompting role without affecting the normal separation and picking of covers.

[0039] In one embodiment of the power mechanism 7, the power mechanism 7 is a rotary drive mechanism, such as a motor or a rotary cylinder, for driving the storage cover mechanism 1 to rotate, and the two or more storage cover cavities are circumferentially arranged on the storage cover mechanism 1 around the rotation axis of the storage cover mechanism 1.

[0040] In another embodiment of the power mechanism 7, the power mechanism 7 is a linear drive mechanism, such as a pneumatic cylinder, an oil cylinder or a linear module, which is used to drive the storage cover mechanism 1 to move linearly, and the two or more storage cover cavities are arranged on the storage cover mechanism 1 at intervals along the linear movement direction of the storage cover mechanism 1.

[0041] like Figure 1 As shown, the utility model further includes a body shell 9 for installation and protection of the above mechanism. The storage cover mechanism 1 is arranged inside the body shell 9, and the top of the body shell 9 is through-arranged to expose the top of the storage cover mechanism 1. The lifting mechanism 3 is arranged inside the body shell 9. The detection mechanism 2 is arranged on the body shell 9 and located on the top side of the storage cover mechanism 1, which is closer to the cover outlet 111 and will not interfere with the movement of the transfer mechanism 5. The detection mechanism 2 can be a photoelectric sensor or other sensors.

[0042] When the storage cover mechanism 1 is rotating, the storage cover mechanism 1 is provided with a rotating shaft and is rotatably connected to the lower end of the body shell 9, a mounting bracket 10 is provided on the top of the body shell 9, a rotary drive mechanism is provided on the mounting bracket 10, and the output end of the rotary drive mechanism is connected to the storage cover mechanism 1 to drive the storage cover mechanism 1 to rotate. When the storage cover mechanism 1 is linearly moving, the storage cover mechanism 1 is slidably matched with the inside of the body shell 9, the linear drive mechanism is provided on one side of the body shell 9, and its output end is connected to the storage cover mechanism 1 to drive the storage cover mechanism 1 to move linearly. In the present utility model, the preferred embodiment of the storage cover mechanism 1 is a rotating embodiment. Compared with the linear moving method, there is no need to reserve a large movable space, and the space required inside the body shell 9 is smaller.

[0043] Among them, an openable cover is provided on the side of the body shell 9, and the operator can add a cover into the cover storage cavity by opening the cover, or directly add a cover into the cover storage cavity through the top of the body shell 9 along the cover outlet 111. The pressing plate 8 can be arranged on the top of the body shell 9 or on the mounting bracket 10, so that it is located above the top of the cover storage mechanism 1.

[0044] The capping mechanism 4 further includes a linear drive module 42, which is disposed on the mounting bracket 10 or on the top of the housing 9. The material dispensing fork 41 is disposed on the output end of the linear drive module 42 and is located on the top of the cap storage mechanism 1. The linear drive module 42 drives the material dispensing fork 41 to move along the top of the cap storage mechanism 1 parallel to the cap outlet 111 to perform the cap dispensing operation. The linear drive module 42 may be an air cylinder, an oil cylinder or other mechanisms. Figure 5 As shown, the dispensing fork 41 is specifically U-shaped. When the dispensing fork 41 extends to the side of the uppermost lid and is located above the lower lid, the uppermost lid is located between the U-shaped areas of the dispensing fork 41. This arrangement can provide limited blocking on both sides above the top of the lower lid, and the limited blocking effect is better, which can prevent the lower lid from tilting on one side. Preferably, a circle of edges is provided on the top edge of the lid to increase the contact area between the dispensing fork 41 and the top of the lid, further improving the blocking effect on the lower lid. When the lid is a paper lid, since the material is relatively soft, the edges can be set to a rolled shape, that is, the same structure as the edges of the mouth of a disposable paper cup. In the case where there is an edge on the top of the lid, it is further preferred that the end of the dispensing fork 41 is set to a pointed tip, which can facilitate the dispensing fork 41 to extend between the edges of the uppermost lid and the lower lid.

[0045] In one embodiment of the utility model, the lifting mechanism 3 is located at the bottom of the storage cover mechanism 1. The storage cover mechanism 1 is located at the bottom of the storage cover cavity and is provided with an opening 121 for the lifting part to pass through. The lifting part pushes the stacked covers 100 from bottom to top to move toward the cover outlet 111.

[0046] In another embodiment of the utility model, the lifting mechanism 3 includes a lifting module 31 and a support plate 32. The lifting module 31 can be a cylinder, an oil cylinder or a linear motor. The support plate 32 is arranged on the output end of the lifting module 31, and the support plate 32 forms the lifting part of the lifting mechanism 3. The lifting module 31 is arranged in the body shell 9 and located on the side of the storage cover mechanism 1. The storage cover mechanism 1 is located on the side of the storage cover cavity and is provided with a movable groove for the support plate 32 to move along the height direction of the storage cover cavity. This arrangement can not only realize the pushing of the stacked covers 100 toward the cover outlet 111, but also arrange the lifting mechanism 3 on the side of the storage cover mechanism 1 to avoid occupying the overall height space of the device.

[0047] In the embodiment in which a movable groove is provided on the side of the storage cover mechanism 1, if the number of storage cover cavities is one, the lifting part can always be located in the storage cover cavity, so it is directly arranged in the storage cover cavity along the movable groove. When there are more than two storage cover cavities, the storage cover mechanism 1 is provided with an opening 121 for the support plate 32 to pass through at the bottom of each storage cover cavity, and the opening 121 is connected to the movable groove. The setting of the opening 121 is combined with the lifting module 31 to drive the support plate 32 to lift and lower. When the storage cover mechanism 1 is rotated or moved to switch the storage cover cavity, it is convenient for the support plate 32 to move into or out of the target storage cover cavity. Specifically, when it is necessary to switch the lifting mechanism 3 to push several covers 100 stacked in other storage cover cavities, the lifting module 31 is used to drive the support plate 32 to move downward along the opening 121 to exit the storage cover cavity where it is located. The storage cover mechanism 1 is rotated or moved so that the opening 121 at the bottom of another storage cover cavity is located below the support plate 32, and the lifting module 31 drives the support plate 32 to move upward to push the stacked covers. Preferably, the width of the opening 121 is smaller than the width or diameter of a single cover to prevent the cover from falling downward from the opening 121 .

[0048] like Figure 2-Figure 4 As shown, the storage cover mechanism 1 includes an upper support plate 11, a lower support plate 12 and a rod body assembly, the rod body assembly is arranged between the upper support plate 11 and the lower support plate 12, and the number of rod body assemblies corresponds to the number of storage cover cavities, a single rod body assembly includes more than three limiting rods 13, one end of the more than three limiting rods 13 is connected to the upper support plate 11, and the other end is connected to the lower support plate 12, the more than three limiting rods 13 are arranged at intervals, the storage cover cavity is formed between the more than three limiting rods 13, the movable groove is formed between two adjacent limiting rods 13 in the single rod body assembly, and the interval between two adjacent limiting rods 13 in the single rod body assembly is smaller than the width or diameter of the cover, so as to prevent the cover from falling out along the movable groove, the cover outlet 111 is arranged on the upper support plate 11, and the opening 121 is arranged on the lower support plate 12, the upper support plate 11 forms the top of the storage cover mechanism 1, and the lower support plate 12 forms the bottom of the storage cover mechanism 1. This arrangement not only meets the structural design requirements of the storage cover mechanism 1, but also has a simple structure, is easy to process, requires less material, and has lower production costs.

[0049] The transfer mechanism 5 is a two-axis or three-axis moving module, that is, it includes a moving stroke of at least two axes of the X-axis, Y-axis and Z-axis, and has a stroke for driving the picking mechanism 6 to move up and down to pick up and press down the lid, and has a stroke for driving the picking mechanism 6 to move horizontally to above the lid outlet 111 and above the crucible. The specific structure is the prior art and will not be repeated here. Preferably, the picking mechanism 6 is a vacuum suction cup, which is connected to a vacuum device to achieve the suction and release of the lid by the vacuum suction cup. The force applied to the lid when the vacuum suction cup picks up the lid is suction. By adsorbing the surface of the lid to pick up the lid, the stability of picking up the lid is higher than that of other picking mechanisms 6.

[0050] The utility model also includes a controller, which can be set on the body shell 9 or at other external locations. The detection mechanism 2, the lifting module 31, the linear drive module 42, the transfer mechanism 5, the power mechanism 7 and the vacuum equipment connected to the vacuum suction cup are all electrically connected or signal-connected to the controller and work in coordination with the controller.
