AI Technical Summary
In existing online film rolling and cutting forming devices, heat is lost during the heating and subsequent conveying of the film, making it difficult to guarantee the hot pressing effect. Furthermore, the suction cup may deviate from its gripping function, resulting in misalignment of the film position.
The membrane conveying mechanism driven by a robotic arm, combined with a membrane positioning mechanism and a heat sealing head, ensures that the membrane block does not deviate during the heat sealing process. The robotic arm and lifting drive system accurately transfer the membrane block to the positioning hole for heat sealing. The precise positioning and heating of the membrane block are achieved by the cooperation of the lifting drive and the transverse seat.
To prevent membrane misalignment during heat sealing, ensure accurate positioning of the membrane block after heat sealing, guarantee hot pressing temperature, improve hot pressing effect, and achieve precise positioning and efficient heat sealing of the membrane block.

Abstract
Description
Technical Field
[0001] This invention relates to the field of food and pharmaceutical packaging machinery and equipment, and in particular to a wire roll film cutting and heat sealing device and a wire roll film cutting and heat sealing system. Background Technology
[0002] Existing online roll-to-roll film cutting and forming equipment includes a frame, on which are mounted a film supply mechanism, a film guiding mechanism, a film cutting mechanism, a film suction mechanism, a lifting mechanism for driving the film suction mechanism up and down, and a turning mechanism for driving the film suction mechanism to flip. The film supply mechanism includes a film unwinding device and a waste film collection device. The film guiding mechanism includes multiple guide rollers, each guide roller conveying the film from the film unwinding device to the film cutting mechanism for cutting into sealing films. The film suction mechanism is connected to the lifting mechanism and the turning mechanism via a rotating shaft to drive the film suction mechanism to flip. The film cutting mechanism is located above the film suction mechanism, and a cup sleeve for the film to be sealed is located below the film suction mechanism. The film suction mechanism includes a suction head base and multiple suction cups mounted on the suction head base. A heating mechanism for heating the sealing film on the suction cups and a detection mechanism for detecting the sealing film on the suction cups are located on the side of the film suction mechanism. Existing online roll-to-roll film cutting and forming equipment has the following drawbacks:
[0003] (1) The film suction mechanism is a rotating film feeding mechanism. The film on the film cutting mechanism (cutting station) is first sent to the heating mechanism (heating station). After being heated by the heating mechanism, it is sent to the sealing station. During the subsequent conveying process, the film loses heat and the hot pressing temperature at the sealing station cannot be determined. The hot pressing effect is difficult to guarantee.
[0004] (2) The suction cup has a certain deviation in film suction and lacks a positioning device, which may lead to a deviation in film position. Since the film cannot be positioned, there may be a problem that the position of the film does not correspond after heat sealing. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a wire roll film cutting and heat sealing device and a wire roll film cutting and heat sealing system to prevent film deviation during heat sealing, avoid the problem of misalignment of film block position after heat sealing, ensure that the film block reaches the hot pressing temperature at the sealing station, and guarantee the hot pressing effect.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] A wire roll film cutting and heat sealing device includes a film cutting mechanism, a film sealing mechanism, a film conveying mechanism, and a film supply mechanism for supplying film to the film cutting mechanism. A film positioning mechanism is provided below the film sealing mechanism. The film conveying mechanism includes a robotic arm for picking up and placing film and a robotic arm drive for driving the robotic arm to reciprocate between the film cutting mechanism and the film positioning mechanism. The film sealing mechanism includes a first lifting drive and a heat sealing head. The heat sealing head is disposed on the first lifting drive and located above the film positioning mechanism.
[0008] As a further improvement to the above technical solution:
[0009] The robotic arm includes a transverse base, a lifting base, a robotic arm, and a suction nozzle. The transverse base is mounted on the robotic arm drive. The lifting base is slidably mounted on the transverse base. The robotic arm is mounted on the lifting base. The suction nozzle is mounted on the robotic arm. The transverse base is mounted on the robotic arm drive. The lifting base is connected to a second lifting drive.
[0010] The robotic arm is driven by a linear motor.
[0011] The second lifting drive is a pneumatic cylinder, hydraulic cylinder, or electric cylinder.
[0012] The membrane positioning mechanism includes a positioning plate that is raised and lowered and a lifter for driving the positioning plate to rise and fall. The positioning plate has a positioning hole through it, and the heat sealing head is located directly above the positioning hole.
[0013] The lifting device is a pneumatic cylinder, hydraulic cylinder, or electric cylinder.
[0014] The first lifting drive is a pneumatic cylinder, hydraulic cylinder, or electric cylinder.
[0015] The film supply mechanism includes a film winding assembly and a film guiding assembly.
[0016] The wire roll film cutting and heat sealing device also includes a frame, on which the film cutting mechanism, sealing mechanism, first lifting drive, robotic arm drive and film positioning mechanism are all mounted.
[0017] A wire roll film cutting and heat sealing system includes the above-mentioned wire roll film cutting and heat sealing device, wherein a reagent delivery mechanism is provided below the film positioning mechanism.
[0018] Compared with the prior art, the advantages of the present invention are as follows:
[0019] The production process of the wire-wound film cutting and heat-sealing device of the present invention is as follows: a film supply mechanism supplies film to a film cutting mechanism, which cuts the film into film blocks. A robotic arm, driven by a robotic arm drive, transfers the cut film blocks to a film positioning mechanism. A heat-sealing head, driven by a first lifting drive, moves downwards and heat-seales the film blocks from the film positioning mechanism onto a reagent kit below the film positioning mechanism. The robotic arm, driven by a robotic arm drive, reciprocates between the film cutting mechanism and the film positioning mechanism to transfer the film blocks accurately to the film positioning mechanism. The film positioning mechanism positions the film blocks to prevent them from deviating during the downward pressing of the heat-sealing head, thus avoiding misalignment after heat sealing. The heat-sealing head heats the film blocks while pressing them down, ensuring that the film blocks reach the heat-sealing temperature at the capping station, guaranteeing the heat-sealing effect. This wire-wound film cutting and heat-sealing device prevents film deviation during heat sealing, avoids misalignment after heat sealing, ensures the film blocks reach the heat-sealing temperature at the capping station, and guarantees the heat-sealing effect.
[0020] The wire-wound film cutting and heat-sealing device of the present invention has the following transfer process: First, the robotic arm drives the transverse shifter to adjust its position so that the suction nozzle is positioned above the cut film block on the film cutting mechanism. Then, a second lifting drive lowers the robotic arm and suction nozzle until the suction nozzle picks up the cut film block. Next, the second lifting drive raises the robotic arm and suction nozzle to an appropriate position, and the robotic arm drives the transverse shifter to move laterally, transferring the film block to the film positioning mechanism. Then, the robotic arm returns to complete the transfer of the next film block. The device has a simple structure and is easy to operate.
[0021] The wire roll film cutting and heat sealing system of the present invention has all the advantages of the wire roll film cutting and heat sealing device, namely, preventing the film from deviating during the heat sealing process, avoiding the problem of misalignment of the film block after heat sealing, ensuring that the film block reaches the hot pressing temperature at the sealing station, and guaranteeing the hot pressing effect.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0034] Example 1:
[0035] Figures 1 to 5 An embodiment of the wire roll film cutting and heat sealing device of the present invention is shown. The wire roll film cutting and heat sealing device includes a film cutting mechanism 1, a film sealing mechanism 2, a film conveying mechanism 3, and a film supplying mechanism 4 for supplying film to the film cutting mechanism 1. A film positioning mechanism 5 is provided below the film sealing mechanism 2. The film conveying mechanism 3 includes a robotic arm 32 for picking up and placing film and a robotic arm drive 31 for driving the robotic arm 32 to reciprocate between the film cutting mechanism 1 and the film positioning mechanism 5. The film sealing mechanism 2 includes a first lifting drive 21 and a heat sealing head 22. The heat sealing head 22 is disposed on the first lifting drive 21 and located above the film positioning mechanism 5.
[0036] Production Process: The film supply mechanism 4 supplies film to the film cutting mechanism 1, which cuts the film into pieces. The robotic arm 32, driven by the robotic arm drive 31, transfers the cut film pieces to the film positioning mechanism 5. The heat sealing head 22, driven by the first lifting drive 21, moves downwards, heat-sealing the film pieces on the film positioning mechanism 5 onto the reagent kit below. Driven by the robotic arm drive 31, the robotic arm 32 reciprocates between the film cutting mechanism 1 and the film positioning mechanism 5 to transfer the film pieces accurately to the film positioning mechanism 5. The film positioning mechanism 5 positions the film pieces to prevent them from deviating during the downward pressing of the heat sealing head 22, thus avoiding misalignment after heat sealing. The heat sealing head 22 heats the film pieces while pressing them down, ensuring they reach the hot-pressing temperature at the capping station, guaranteeing the heat-pressing effect. This film winding, cutting, and heat-sealing device prevents the film from deviating during the heat-sealing process, avoiding misalignment of the film blocks after heat sealing, ensuring that the film blocks reach the heat-pressing temperature at the sealing station, and guaranteeing the heat-pressing effect.
[0037] In this embodiment, as Figure 2 and Figure 3 As shown, the robotic arm 32 includes a transverse base 321, a lifting base 322, a robotic arm 323, and a suction nozzle 324. The transverse base 321 is mounted on the robotic arm drive 31. The lifting base 322 is slidably mounted on the transverse base 321. The robotic arm 323 is mounted on the lifting base 322. The suction nozzle 324 is mounted on the robotic arm 323. The transverse base 321 is mounted on the robotic arm drive 31. The lifting base 322 is connected to a second lifting drive 325.
[0038] Transfer process: First, the robotic arm drive 31 moves the transverse seat 321 laterally to adjust it, positioning the suction nozzle 324 above the cut film block on the film cutting mechanism 1. Then, the second lifting drive 325 lowers the robotic arm 323 and the suction nozzle 324 until the suction nozzle 324 picks up the cut film block on the film cutting mechanism 1. Next, the second lifting drive 325 raises the robotic arm 323 and the suction nozzle 324 to an appropriate position, and the robotic arm drive 31 moves the transverse seat 321 laterally to transfer the film block to the film positioning mechanism 5. Then, the robotic arm 32 returns to its original position to transfer the next film block. The structure is simple and the operation is convenient.
[0039] In this embodiment, the robotic arm drive 31 is a linear motor. The second lifting drive 325 is a pneumatic cylinder, hydraulic cylinder, or electric cylinder.
[0040] In this embodiment, as Figure 4As shown, the membrane positioning mechanism 5 includes a positioning plate 51 that is raised and lowered, and a lifter 52 for driving the positioning plate 51 to rise and fall. A positioning hole 511 is passed through the positioning plate 51, and the heat sealing head 22 is located directly above the positioning hole 511. The positioning hole 511 passes through the upper and lower surfaces of the positioning plate 51. The robot arm 32 transfers the cut membrane block to the positioning hole 511, and the heat sealing head 22 passes through the positioning hole 511 to heat seal the membrane block onto the reagent kit below. Under the limiting effect of the positioning hole 511, the membrane block is prevented from deviating.
[0041] In this embodiment, the lifting device 52 is a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder. The first lifting drive 21 is a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder. The heat-sealing head 22 is located at the bottom end of the first lifting drive 21.
[0042] In this embodiment, as Figure 1 and Figure 2 As shown, the film supply mechanism 4 includes a film winding assembly 41 and a film guiding assembly 42. The rolled film is placed on the film winding assembly 41, and the extended end is conveyed forward through the film guiding assembly 42.
[0043] In this embodiment, the wire roll film cutting and heat sealing device also includes a frame 6, and the film cutting mechanism 1, the film sealing mechanism 2, the first lifting drive 21, the robotic arm drive 31 and the film positioning mechanism 5 are all mounted on the frame 6.
