Description

Technical Field

[0001] This invention relates to the field of culture vessel preparation, and in particular to an automatic cutting and welding film cutting device for culture vessel covers. Background Technology

[0002] A culture vessel is a container used to culture and observe substances such as bacteria and fungi. It contains culture medium and cells for cell culture. During cell culture, a lid is usually placed on the culture vessel for protection and sealing to prevent bacterial infection and inhibit pH rise in the culture medium. Furthermore, observations of morphological changes, motility, and infiltration capabilities of cultured cells over time are mostly conducted while the culture vessel is sealed with the lid on.

[0003] Currently, when preparing the top cover of the culture vessel, it is necessary to lay and connect the filter membrane to the top cover. This operation is basically done manually. That is, the top cover and filter membrane are picked up manually, the filter membrane is laid on the inside of the top cover, and the filter membrane is fixed to the top cover by means of heat fusion or other methods. However, manual operation is slow and is prone to failure due to large errors in the fixed position of the filter membrane. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic cutting and welding device for culture vessel covers that can improve the preparation efficiency of culture vessel covers and avoid human error.

[0005] To solve the above-mentioned technical problems, the present invention provides an automatic cutting and welding device for incubator covers, including a rotating disk, a plurality of carriers spaced apart along the circumference of the rotating disk, and a plurality of processing positions formed on the surface of the carriers. The outer circumference of the rotating disk is sequentially provided with a cover feeding component, a filter membrane feeding component, and a hot melt welding component, so that the cover is fed to the corresponding processing position by the cover feeding component, and the filter membrane is fed to the corresponding cover by the filter membrane feeding component and fixed to the cover by the hot melt welding component, forming a cover with a filter membrane. The rotating disk also has a feeding component on its side, which includes a horizontally movable feeding seat, a plurality of feeding grippers connected to the feeding seat in a lifting manner, and a discharge channel inclinedly arranged on the side of the rotating disk, so that the feeding grippers can pick up the cover with the filter membrane and move it to the discharge channel for placement.

[0006] Furthermore, the upper cover feeding component includes a vibratory plate located on the side of the rotating plate, and a feeding seat that is reciprocally moved between the outlet end of the vibratory plate and the rotating plate. Several grippers are raised and lowered on the lower side of the feeding seat so that the grippers can transfer the upper cover at the outlet end of the vibratory plate to the corresponding processing position.

[0007] Furthermore, the upper cover feeding component also includes a positioning plate, the feeding seat is movably mounted on the positioning plate, and a positioning cylinder is connected to the side of the positioning plate. The piston rod of the positioning cylinder in the extended state and the retracted state forms at least two positioning points, so that the feeding seat is limited by the stroke of the positioning points.

[0008] Furthermore, the filter membrane feeding component includes a cutting platform located on the side of the rotating disk, and a feeding seat reciprocatingly disposed between the cutting platform and the rotating disk. The feeding seat has several lifting and lowering punching rods on its lower side, and each punching rod has an adsorption block at its end. The lower surface area of ​​the adsorption block is the same as the area of ​​the filter membrane. The cutting platform has cutting holes that correspond one-to-one with the adsorption blocks. The cutting platform has a horizontally penetrating feeding channel so that when the filter membrane raw material is conveyed through the feeding channel, it is punched by the adsorption block and the cutting hole and then adsorbed by the adsorption block.

[0009] Furthermore, a first moving plate and a second moving plate are respectively movably arranged on both sides of the cutting platform, and a first pressure plate is raised and lowered on the first moving plate, and a second pressure plate is raised and lowered on the second moving plate, so that the filter membrane raw material passes through the space between the first pressure plate and the first moving plate, the feeding channel, and the space between the second pressure plate and the second moving plate in sequence.

[0010] Furthermore, the cutting platform has a material transfer platform on its side, and a material transfer seat is movably mounted on the material transfer platform. The first moving plate and the second moving plate are both connected to the material transfer seat so that the first moving plate and the second moving plate move synchronously.

[0011] Furthermore, the cutting holes at the cutting platform are arranged in an alternating pattern.

[0012] Furthermore, a leveling component is provided between the upper cover feeding component and the filter membrane feeding component. The leveling component includes a support base and a pressing plate that is lifted and disposed on the side of the support base. The bottom of the pressing plate has a plurality of pressing blocks that match the processing positions, and there is an elastic element between the pressing blocks and the pressing plate so that when the carrier moves to the underside of the pressing plate, the plurality of pressing blocks press down on the corresponding processing positions.

[0013] Furthermore, a detection component is provided between the hot melt welding component and the unloading component. The detection component includes a column and a camera connected to the side of the column near the rotating disk. The camera is used for visual detection to determine whether the cover with the filter membrane is a defective product, and a light source is provided below the camera.

[0014] Furthermore, the feeding component also includes a waste box located below the discharge channel. The discharge channel is movable so that when the feeding gripper picks up a defective product, the discharge channel moves away from the rotating disk and exposes the waste box.

[0015] The beneficial effects of this invention are as follows: the rotation of the rotating disk drives each carrier to rotate circumferentially. When one of the carriers moves to the corresponding position of the cover feeding component, the cover is transported to the processing position of the carrier by the cover feeding component. Then the rotating disk continues to rotate, causing the cover to move with the carrier to the filter membrane feeding component. At this time, the cut filter membrane is transported to the corresponding position of each cover by the filter membrane feeding component, so that the filter membrane and the cover are initially positioned. When the rotating disk continues to rotate and drives the carrier to the hot melt welding component, the filter membrane is welded and fixed to the cover by hot melt welding to achieve the processing purpose of the cover and the filter membrane. Finally, the cover with the filter membrane is picked up by the unloading claw. At the same time, the movement of the unloading seat can make the finished product stably unloaded from the discharge channel. Since the above processes can be carried out simultaneously, that is, the cover feeding, filter membrane feeding, hot melt welding and other processes can be carried out simultaneously on the products at different carriers, thereby greatly improving the production efficiency and reducing the probability of defective products caused by human error.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0030] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0031] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0032] like Figures 1-12The present invention provides an automatic cutting and welding device for a culturer cover, comprising a rotating disk 1, a plurality of carriers 11 spaced apart along the circumference of the rotating disk 1, and a plurality of processing positions 12 formed on the surface of the carriers 11. The outer circumference of the rotating disk 1 is sequentially provided with a cover feeding component 2, a filter membrane feeding component 3, and a hot melt welding component 4, so that the cover is fed to the corresponding processing position 12 by the cover feeding component 2, and the filter membrane is fed to the corresponding cover by the filter membrane feeding component 3 and fixed to the cover by the hot melt welding component 4, forming a cover with a filter membrane. The rotating disk 1 also has a feeding component 5 on its side, the feeding component 5 including a horizontally movable feeding seat 51, a plurality of feeding claws 52 connected to the feeding seat 51, and a discharge channel 53 inclined on the side of the rotating disk 1, so that the feeding claws 52 can grasp the cover with the filter membrane and move it to the discharge channel 53 for lowering.

[0033] The rotation of the rotating disk 1 causes each carrier 11 to rotate circumferentially. When one of the carriers 11 moves to the corresponding position of the upper cover feeding component 2, the upper cover is transported to the processing position 12 of the carrier 11 by the upper cover feeding component 2. Then the rotating disk 1 continues to rotate, causing the upper cover to move with the carrier 11 to the filter membrane feeding component 3. At this time, the filter membrane feeding component 3 transports the cut filter membrane to the corresponding position of each upper cover, so that the filter membrane and the upper cover are initially positioned. The rotating disk 1 continues to rotate and causes the carrier 11 to move to the hot melt welding part. When there are 4 parts, the filter membrane is welded and fixed to the top cover by hot melt welding to achieve the processing purpose of the top cover and the filter membrane. Finally, the top cover with the filter membrane is picked up by the unloading claw 52. At the same time, the movement of the unloading seat 51 can make the finished product stably unloaded from the discharge channel 53. Since the above processes can be carried out simultaneously, that is, the processes of top cover loading, filter membrane loading, hot melt welding, etc. can be processed on products at different carriers 11 at the same time, which greatly improves the preparation efficiency and reduces the probability of defective products caused by human error.

[0034] The rotating disk 1 is controlled by a servo motor to rotate and start / stop. The carrier 11 is connected to the rotating disk 1 by bolts or other detachable connections to facilitate the replacement of carriers 11 with different processing positions 12 to adapt to different product lines. In this solution, the carrier 11 has four processing positions 12, which can simultaneously process four top covers and filter membranes. The unloading seat 51 is controlled to move by a servo motor in conjunction with a lead screw drive and guide rail. A cylinder or hydraulic cylinder is provided at the unloading seat 51 to control the lifting and lowering of the unloading gripper 52. The structure and usage of the unloading gripper 52 are the same as the existing mechanical gripper 23, and will not be described in detail here.

[0035] In one embodiment of this solution, the hot melt welding component 4 includes at least two sets of hot melt welding stations, and each set of hot melt welding stations includes at least two hot melt welding heads, that is, each hot melt welding head corresponds to a processing position 12. The hot melt welding head is driven to rise and fall by a telescopic rod controlled by hydraulic or pneumatic pressure, thereby performing hot melt welding on the filter membrane.

[0036] Preferably, the upper cover feeding component 2 includes a vibratory plate 21 located on the side of the rotating plate 1 and a feeding seat 22 that is reciprocally moved between the outlet end of the vibratory plate 21 and the rotating plate 1. The feeding seat 22 has several grippers 23 that are raised and lowered on its lower side so that the grippers 23 can transfer the upper cover at the outlet end of the vibratory plate 21 to the corresponding processing position 12.

[0037] Specifically, the upper cover is fed sequentially by the vibratory feeder 21, ensuring that the upper cover faces the same direction. Then, the feeding seat 22 drives the gripper 23 to move to the outlet end of the vibratory feeder 21. The gripper 23 descends to pick up the upper cover and then rises to reset. The feeding seat 22 drives the gripper 23 to move to the corresponding carrier 11, so that the gripper 23 descends and places the upper cover in the corresponding processing position 12, thus completing the upper cover feeding action.

[0038] The loading seat 22 is controlled to move by a servo motor in conjunction with a lead screw and guide rail. A cylinder or hydraulic cylinder is provided at the loading seat 22 to control the lifting and lowering of the gripper 23. It is worth mentioning that the gripper 23 can adopt the existing mechanical gripper 23, or it can use negative pressure adsorption to adsorb and pick up the material from the top cover.

[0039] Preferably, the upper cover feeding component 2 further includes a positioning plate 24, the feeding seat 22 is movably mounted on the positioning plate 24, and a positioning cylinder 25 is connected to the side of the positioning plate 24. The piston rod 26 of the positioning cylinder 25 forms at least two positioning points in the extended state and the retracted state, so that the feeding seat 22 is limited by the stroke of the positioning points.

[0040] Specifically, the positioning plate 24 supports the loading seat 22 and the positioning cylinder 25, etc. At the same time, when the loading seat 22 reciprocates to load the material, the positioning cylinder 25 controls the piston rod 26 to extend or retract, so that the piston rod 26 has a positioning point when it extends and another positioning point when it retracts. After the gripper 23 picks up the top cover, the loading seat 22 moves and resets. At this time, the loading seat 22 moves and abuts the end of the piston rod 26, so that the extension or retraction state of the piston rod 26 can limit the two strokes of the loading seat 22, thereby accurately controlling the reset position of the loading seat 22, so as to ensure that the gripper 23 can transport the top cover to different processing positions 12.

[0041] It is worth mentioning that in this solution, the four processing positions 12 at the carrier 11 are arranged in pairs, so that the loading seat 22 only needs a single positioning cylinder 25 to meet the positioning requirements. When it is necessary to increase the processing position 12 or the positioning position, more positioning points can be obtained by adding positioning cylinders 25.

[0042] Preferably, the filter membrane feeding component 3 includes a cutting platform 31 located on the side of the rotating disk 1 and a feeding seat 32 reciprocally disposed between the cutting platform 31 and the rotating disk 1. The feeding seat 32 has a plurality of lifting and lowering punch rods 33 on its lower side. The end of each punch rod 33 has an adsorption block 34. The lower surface area of ​​the adsorption block 34 is the same as the area of ​​the filter membrane. The cutting platform 31 is provided with cutting holes 35 corresponding to the adsorption blocks 34. The cutting platform 31 is horizontally provided with a feeding channel 36 so that when the filter membrane raw material 37 is conveyed through the feeding channel 36, the adsorption block 34 matches and punches the material with the cutting hole 35, and then adsorbs the filter membrane through the adsorption block 34.

[0043] Specifically, when the carrier 11 with the cover rotates to the filter membrane feeding component 3, the feeding seat 32 drives the adsorption block 34 to move to the upper part of the cutting platform 31. At the same time, the filter membrane material 37 moves a certain distance along the feeding channel 36, so that the uncut part of the filter membrane material 37 is located at the cutting hole 35. Then, the punching rod 33 descends, so that the adsorption block 34 enters the cutting hole 35. Then, the adsorption block 34 and the cutting hole 35 punch the filter membrane material 37 at this position. The punched filter membrane is adsorbed and fixed by the adsorption block 34. When the punching rod 33 drives the adsorption block 34 to rise, the filter membrane rises synchronously. Then, the filter membrane is moved to the cover by the reset movement of the feeding seat 32, thus completing the single filter membrane cutting and feeding action.

[0044] In one embodiment of this solution, the feeding seat 32 is moved by a cylinder in conjunction with a guide rail, and the feeding seat 32 has a cylinder or hydraulic cylinder for controlling the lifting and lowering of the stamping rod 33.

[0045] It is worth mentioning that the bottom surface of the cutting hole 35 is lower than the bottom surface of the feeding channel 36, so that when the adsorption block 34 is pressed down to the bottom of the cutting hole 35, the filter membrane material 37 can be completely cut circumferentially to ensure the complete separation of the filter membrane edge. At the same time, the bottom of the adsorption block 34 has several adsorption holes, which are connected to the adsorption block 34 through a negative pressure device to provide negative pressure suction to each adsorption hole. Then, the filter membrane is adsorbed and positioned by the negative pressure suction. It should be noted that although the filter membrane in this solution is a breathable structure, the filter membrane itself is lightweight. Therefore, when the negative pressure suction is sufficient, the filter membrane can be stably adsorbed at the adsorption block 34 until it is placed in the upper cover position.

[0046] In a preferred embodiment of this solution, a connecting seat 314 is connected between the stamping rod 33 and the feeding seat 32. The connecting seat 314 is raised and lowered, and the stamping rod 33 and the connecting seat 314 are in movable engagement so that when the stamping rod 33 moves relative to the connecting seat 314, the distance between adjacent stamping rods 33 is adjusted. Specifically, when the connecting seat 314 structure is provided, the cylinder or hydraulic cylinder at the feeding seat 32 is used to control the raising and lowering of the connecting seat 314, thereby driving multiple stamping rods 33 to raise and lower synchronously. At the same time, a pneumatic or hydraulic rod can be provided between two adjacent stamping rods 33 to control the adjustment of the moving distance between adjacent stamping rods 33, so that the adsorption blocks 34 can move closer to each other when punching the filter membrane to reduce the waste area of ​​the filter membrane raw material 37, and can separate from each other when the filter membrane is placed on the top cover to adapt to the spacing of the processing position 12.

[0047] Preferably, a first moving plate 38 and a second moving plate 39 are respectively movably arranged on both sides of the cutting platform 31, and a first pressure plate 310 is raised and lowered on the first moving plate 38, and a second pressure plate 311 is raised and lowered on the second moving plate 39, so that the filter membrane raw material 37 passes sequentially between the first pressure plate 310 and the first moving plate 38, the feeding channel 36, and between the second pressure plate 311 and the second moving plate 39.

[0048] Specifically, when the filter membrane material 37 needs to be moved, the first pressure plate 310 and the second pressure plate 311 press the first moving plate 38 and the second moving plate 39 respectively, so that the positions of the filter membrane material 37 on both sides of the cutting platform 31 are clamped and fixed. At this time, the first moving plate 38 and the second moving plate 39 move synchronously, thereby driving the filter membrane to move along the feeding channel 36, thereby moving the uncut filter membrane material 37 to the cutting hole 35. At the same time, when the filter membrane material 37 is punched by the adsorption block 34 in conjunction with the cutting hole 35, the stability of both sides of the punching position can be ensured by the pressing and positioning of the first pressure plate 310 and the second pressure plate 311, so as to improve the flatness of the punched edge of the filter membrane.

[0049] Both the first movable plate 38 and the second movable plate 39 are equipped with cylinders to control the lifting and pressing actions of the first pressure plate 310 and the second pressure plate 311.

[0050] Preferably, the cutting platform 31 has a material transfer platform 312 on its side, and a material transfer seat 313 is movably mounted on the material transfer platform 312. The first moving plate 38 and the second moving plate 39 are both connected to the material transfer seat 313 so that the first moving plate 38 and the second moving plate 39 move synchronously.

[0051] Specifically, the material transfer seat 313 drives the first moving plate 38 and the second moving plate 39 to move synchronously, thereby controlling the stable movement of the filter membrane material 37.

[0052] The transfer seat 313 is controlled to move back and forth by means of a servo motor, a lead screw, and a guide rail.

[0053] Preferably, the plurality of cutting holes 35 at the cutting platform 31 are staggered to maximize the proportion of the cutting position of the filter membrane material 37, effectively saving the wasted area of ​​the filter membrane material 37.

[0054] In one embodiment of this solution, the width of the incoming membrane roll is 53mm, and the cutting holes 35 have two rows. The angle between the center line connecting the adjacent holes of the two rows of cutting holes 35 and the feeding direction of the filter membrane material 37 is 55°, so as to maximize the utilization of the area of ​​the filter membrane material 37. Compared with the 60° layout that saves the most material, the membrane edge is only 1.01mm away from the material side after the material is dropped, which has an adverse effect on the operation of the equipment. When the angle is 55°, the membrane edge is 2.94mm away from the material side, which can better adapt to the width of the incoming membrane roll and avoid the problem of membrane swaying.

[0055] Preferably, a leveling component 6 is provided between the upper cover feeding component 2 and the filter membrane feeding component 3. The leveling component 6 includes a support base 61 and a pressing plate 62 that is lifted and disposed on the side of the support base 61. The bottom of the pressing plate 62 has a plurality of pressing blocks 63 that match the processing position 12, and there is an elastic element 64 between the pressing blocks 63 and the pressing plate 62, so that when the carrier 11 moves to the lower side of the pressing plate 62, the plurality of pressing blocks 63 press down on the corresponding processing position 12.

[0056] Specifically, after the top cover is placed in the processing position 12, the rotating disk 1 rotates the carrier 11 to the leveling component 6. At this time, the pressing plate 62 descends, so that each pressing block 63 presses and levels the processing position 12 to ensure the stability of the top cover in the processing position 12 and avoid the situation where the top cover is not completely placed in the processing position 12.

[0057] The pressing plate 62 is raised and lowered by a cylinder or hydraulic cylinder, and the elastic element 64 can adopt a structure of spring and telescopic rod to ensure that the pressing block 63 has sufficient pressing force while not causing damage to the upper cover.

[0058] Preferably, a detection component 7 is provided between the hot melt welding component 4 and the unloading component 5. The detection component 7 includes a column 71 and a camera 72 connected to the column 71 near the rotating disk 1. The camera 72 is used for visual detection of whether the cover with the filter membrane is a defective product, and a light source 73 is provided below the camera 72.

[0059] Specifically, the camera 72 is used to inspect each cover with a filter membrane in the carrier 11. The light source 73 is used to improve the inspection effect. The contrast check is used as the core judgment criterion. The welding circle is fitted by the CCD camera 72 and visual inspection software. If it is too large or too small, it is judged as a defective product, so as to ensure the preparation effect of the filter membrane and the cover.

[0060] Preferably, the unloading component 5 further includes a waste box 54 located below the discharge channel 53. The discharge channel 53 is movable so that when the unloading claw 52 picks up the defective product, the discharge channel 53 moves away from the rotating disk 1 and exposes the waste box 54.

[0061] Specifically, when a defective product is detected by camera 72 in the previous process, when the defective product moves to the unloading part 5, the unloading channel 53 moves away from the rotating disk 1, so that the waste box 54 is exposed. Then, when the unloading claw 52 picks up the defective product, the defective product can fall into the waste box 54.

[0062] The discharge channel 53 can be moved by a cylinder, hydraulic cylinder or motor. When the defective product falls into the waste box 54, the unloading claw 52 that picks up the defective product first unloads it. Then the discharge channel 53 is reset and the qualified product is unloaded. The structure and usage of the unloading claw 52 are the same as the existing mechanical claw 23, and will not be described in detail here.

[0063] This invention is not limited to the preferred embodiments described above. Anyone can derive other products in various forms under the guidance of this invention. However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
