Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device manufacturing technology, and in particular to a heating device. Background Technology
[0002] The assembly of many medical consumables involves bonding at least two separate molded components together. The key to ensuring that the two components are reliably bonded together is to ensure that the adhesive fully covers the area to be bonded, avoiding insufficient adhesive application that results in an inadequate effective bonding area between the two components.
[0003] Currently, the solution to insufficient adhesive coverage is to increase the supply of adhesive. However, this approach has the following drawbacks: adhesive spillage is difficult to control, easily contaminating medical consumable parts; and the large amount of adhesive used results in waste. Furthermore, increasing adhesive coverage through orderly adhesive application increases production time for medical consumables, impacting production capacity. Summary of the Invention
[0004] In view of this, the present invention provides a heating device for heating medical consumables, particularly for heating the bonding areas of the medical consumables, to increase the temperature of the bonding areas. Under high-temperature conduction, the adhesive's fluidity increases, thereby accelerating the adhesive overflow rate and achieving wide coverage of the bonding area. The heating device includes:
[0005] The heating mechanism includes a heat release section, which has a heat outlet.
[0006] The delivery mechanism includes a heating section, which drives the medical consumables to move along a preset heating trajectory through the heating section.
[0007] The heat release section can move close to the heated section to reach the heating position. When the heat release section is in the heating position, the heating trajectory passes through the heat outlet.
[0008] In one embodiment, the heat release section includes two air outlets arranged opposite to each other and has two heat outlets that connect the two air outlets.
[0009] In one embodiment, there are multiple heat release sections, which are arranged in rows on one side of the heating section. A material placement gap is formed between the two air outlet sides of any two adjacent heat release sections. The multiple heat release sections are arranged in rows outside one side of the heating section. Alternatively, the multiple heat release sections are arranged in groups outside one side of the heating section, and the multiple heat release sections in any group are arranged in rows.
[0010] With this configuration, multiple heat release units can simultaneously heat multiple medical consumables that are arranged in a continuous row or in groups, thereby improving the heating efficiency of the heating device.
[0011] In one embodiment, when the plurality of heat release parts are in the heating position, the plurality of heat release parts are arranged in a row along the tangential direction of the heating trajectory; or, when the plurality of heat release parts are in the heating position, they are arranged in a row along the extension direction of the heating trajectory.
[0012] With this setup, the arrangement of multiple heat release sections is adapted to the arrangement of multiple medical consumables in the same row, and the heat radiation intensity received by each medical consumable is the same or basically the same, so that each medical consumable can ultimately receive the same degree of heat treatment.
[0013] In one embodiment, each heat release section has two heat outlets, which connect the two oppositely arranged air outlets of the heat release section. When the heat release section is in the heating position, the heating trajectory passes through the two air outlets, and a material placement gap is formed between the two oppositely arranged air outlets of any two adjacent heat release sections.
[0014] With this configuration, when the heat release section reaches the heating position, the material placement gap between two adjacent heat release sections can accommodate one medical consumable. The same heat release section can provide heat to the medical consumables located next to the two air outlets of the heat release section through its two heat outlets, which further improves the heating efficiency of the heating device and reduces the number of heating mechanisms. It is not necessary to configure a heating mechanism for each medical consumable on the same set of material carriers.
[0015] In one embodiment, the conveying mechanism further includes a material carrier, which includes at least two spaced-apart material-bearing components, wherein the width of the gap between any two adjacent material-bearing components is greater than or equal to the distance between the two air outlet sides of the heat release section.
[0016] This configuration avoids collisions and interference with medical consumables and material carriers when the heat release unit moves toward the heating position. In particular, when the gap between the two material carrier components is greater than the distance between the two air outlet sides of the heat release unit, the material carrier is less affected by the heat flow.
[0017] In one embodiment, the heating mechanism further includes a follow-up drive unit, which can drive the heat release unit that has reached the heating position to follow the movement of the medical consumable along a follow-up trajectory, wherein the follow-up trajectory and the heating trajectory at least partially overlap.
[0018] With this configuration, the follow-up drive unit can drive the heat release unit to follow the medical consumable along the trajectory segment where the following trajectory and the heating trajectory overlap for a period of time, thereby extending the time for the medical consumable to be heated and ensuring that the adhesive can fully overflow and achieve wide coverage of the bonding area.
[0019] In one embodiment, the heated section includes a single-curvature curved section, the heating mechanism is disposed on the side of the single-curvature curved section that is relatively far from its curvature center, and the heating position is located on the side of the single-curvature curved section that is relatively far from its curvature center.
[0020] With this configuration, the impact of the heat flow released by the heating mechanism on the conveying mechanism is further reduced, and the conveyor line sections at both ends of the heated section are less likely to be scorched by the heat flow.
[0021] In one embodiment, the conveying mechanism includes a conveyor line and a material carrier that is responsively connected to the conveyor line. The conveyor line includes a heated section, and the material carrier includes a plate.
[0022] With this configuration, the material carrier can dissipate heat outward through the plate, reducing the accumulation of heat on the material carrier and preventing it from overheating and being damaged.
[0023] In one embodiment, the material carrier further includes a carrier body connecting the plate, the carrier body being movably connected to the conveyor line via the plate; and / or, the plate has perforated holes.
[0024] This configuration, with the plate positioned between the carrier body and the conveyor line, can slow down the rate of temperature rise of the conveyor line, preventing overheating caused by heat conduction from the material carrier. The perforated design increases the surface area of the plate, thus improving heat dissipation.
[0025] In one embodiment, the heating device further includes a heat dissipation mechanism, which includes a heat flow hood assembly having a receiving space, within which at least the heat flow release portion can remain; the heat flow hood assembly has a first opening on the side near the heated section through which the heat flow release portion passes to reach the heating position.
[0026] With this configuration, the heat hood assembly can concentrate the heat generated by the heat release section within the containment space, preventing the heat from spreading outward and causing damage to other workstations on the production line.
[0027] In one embodiment, the heat flow hood assembly is further provided with a second opening, which is located on opposite sides of the heat flow hood assembly, respectively. The heat dissipation mechanism also includes an airflow generating component connected to the heat flow hood assembly, which can drive the gas in the accommodating space to flow through the second opening and leave the heat flow hood assembly.
[0028] With this configuration, the airflow generating component can carry away the accumulated heat in the heat flow shroud assembly after it is in operation, thereby preventing heat flow from accumulating in the containment space for a long time.
[0029] In one embodiment, the heat dissipation mechanism further includes a heat flow shielding member disposed on the side of the heat flow shroud assembly opposite to the accommodating space, the heat flow shielding member having a perforated hole; and / or, the heat flow shielding member and the heat flow shroud assembly are spaced apart.
[0030] This design prevents personnel from being burned by the heat flow shield when they accidentally touch the heat dissipation mechanism, thus improving equipment safety. The perforated design also helps the heat flow shield dissipate heat quickly, preventing overheating.
[0031] In one embodiment, the conveying mechanism includes a first material fixing member and a second material fixing member that are spaced apart, and the first material fixing member and the second material fixing member have a positioning reference;
[0032] When the heat release unit is in the heating position, the position of the heat outlet in the positioning reference extension direction is between the position of the first material fixing member in the positioning reference extension direction and the position of the second material fixing member in the positioning reference extension direction.
[0033] With this configuration, the heat flow will not directly act on the first or second material fixing component after it is discharged from the heat flow outlet, thus reducing the scorching of the material fixing component.
[0034] The heating device provided by this invention can heat the bonding area of medical consumables. After the adhesive adheres to the bonding area, it can be heated by the residual heat of the medical consumables, thereby improving its flowability and diffusion rate, achieving wide and sufficient coverage of the bonding area, and increasing the effective bonding area. While heating the medical consumables, the heating device can also mitigate the concentrated diffusion of heat flow to the material carrier or conveying mechanism. If we assume that the heat outlet remains stationary after reaching the heating position following the heat release section, the heating trajectory will pass from one side of the heat outlet to the other side, and then exit from the other side of the heat outlet. This heating trajectory is the path swept by the bonding area of the medical consumables during the heating section driven by the conveying mechanism. Therefore, this invention can significantly change the direction of heat radiation, reduce the rate of heat radiation to the material carrier and conveying mechanism, thereby reducing the probability of overheating in the conveying mechanism. The heating device can operate continuously for a longer period without the need for cooling, ultimately increasing the production capacity of medical consumables. Attached Figure Description

[0040] 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 a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.
[0042] This invention provides a heating device 100 for heating a medical consumable 200. By heating the area to be covered by adhesive, the medical consumable 200 is heated. After the adhesive adheres to the designated bonding area, it is further heated by the residual heat of the medical consumable 200, thereby improving the overflow and diffusion ability of the adhesive. The medical consumable 200 includes a first component and a second component to be bonded. These two components are pre-assembled in a pre-assembly station to form the medical consumable 200. The medical consumable 200 then reaches the heating station corresponding to the heating device 100 for heating. Subsequently, the medical consumable 200 reaches the adhesive coating station, where the adhesive adheres to the area where the first and second components will be bonded together (hereinafter referred to as the bonding area), and overflows under the residual heat of the first and second components, thus covering the surface of the bonding area.
[0043] This invention does not specifically limit the type of the aforementioned medical consumable 200 or the specific structure of its first and second components. The following example of the heating process of a pre-filled syringe is used to illustrate the structure and operating principle of the heating device 100. The first and second components are the tubing and needle of the pre-filled syringe, respectively, and the medical consumable 200 is a whole formed by bonding the tubing and needle together.
[0044] Please see Figures 1 to 2 The heating device 100 includes a heating mechanism 10 and a conveying mechanism 20. The heating mechanism 10 is responsible for delivering heat to the medical consumable 200 that has arrived at the heating station. The conveying mechanism 20 is used to transport the pre-assembled medical consumable 200 to the heating station. After the bonding part of the medical consumable 200 is heated to a preset temperature, it is transported away from the heating station and moves to the next work station.
[0045] The heating mechanism 10 includes a heat flow release section 11 that can directly discharge heat, and a feed drive section 13 for driving the heat flow release section 11 to extend or retract, and has a heat flow channel communicating with a heat source (not shown in the figure). The heat source can be a heating device installed in the heating mechanism 10 or a heating device independent of the heating device 100. The heat flow channel allows heat to flow through its interior, and the heat flow channel passes through two opposite sides of the heat flow release section 11 to form two heat flow outlets 111, and the sides where the two heat flow outlets 111 are located are the two air outlet sides 112 of the heat flow release section 11.
[0046] The feed drive unit 13 drives the heat release unit 11 to move in a stroke that includes two extreme positions: the execution heating position corresponding to the maximum extension distance of the heat release unit 11, and the retraction avoidance position corresponding to the maximum retraction amount / shortest extension distance of the heat release unit 11. When the heat release unit 11 is in the execution heating position, the heat can be directly radiated to the bonding area of the medical consumable 200.
[0047] The conveying mechanism 20 includes a conveyor line 21 for transporting medical consumables 200 to and from the heating station, and a material carrier 22 for carrying the medical consumables 200 and moving along with the conveyor line 21. The conveyor line 21 includes a heating section 211 that passes through the heating station, and the heating position is located on the side of the retraction avoidance position relatively close to the heating section 211.
[0048] Optionally, after the material carrier 22 carrying the medical consumable 200 reaches the heating section 211, the conveyor line 21 stops operating for a period of time. The feed drive unit 13 then drives the heat release unit 11 to extend closer to the heating section 211 until the heat release unit 11 reaches the heating position. The material carrier 22 carrying the medical consumable 200 and the conveyor line 21 simultaneously pause for a period of time to receive heat radiation. After the medical consumable 200 finishes heating up, the feed drive unit 13 drives the heat release unit 11 to retract away from the heating section 211 to reach the retraction avoidance position, thereby avoiding the material carrier 22 and the medical consumable 200. Subsequently, the conveyor line 21 resumes operation, and the material carrier 22 continues to follow the conveyor line 21 to move the medical consumable 200 away from the heating station.
[0049] As mentioned above, in this embodiment, the medical consumable 200 is a pre-assembled and glued whole consisting of a needle and a tubing. Adhesive is applied to the end of the tubing into which the needle is inserted, and a portion of the adhesive adheres to the root of the needle extending from the end of the tubing. In other words, in this embodiment, the area to be bonded includes both the end of the tubing and the root of the needle extending from the tubing. When the medical consumable 200 is carried by the material carrier 22 and moves along the conveyor line 21, the trajectory swept by the area to be bonded during its passage through the heated section 211 forms a preset heated trajectory. The conveying mechanism 20 limits the area to be bonded of the medical consumable 200 to pass through the heated station along the heated trajectory.
[0050] The opening angle / centerline pointing angle of the heat outlet 111 is limited as follows: when the heat release section 11 is in the heating execution position, the heating trajectory passes through the heat outlet 111 of the heat release section 11. If it is assumed that the heat outlet 111 remains stationary after following the heat release section 11 to the heating execution position, then the heating trajectory will pass through the heat outlet 111 from one side and then exit from the other side. In other words, at least one tracking point can be found on the bonding area: ignoring the interruption of the transport line 21 and the pause period of the bonding area, the tracking point moves along the heating trajectory, first reaching one side of the heat outlet 111, and if it is assumed that the heat outlet 111 remains stationary, then the tracking point can move through the interior of the heat outlet 111 and then reach the other side of the heat outlet 111.
[0051] In one embodiment, the heated section 211 includes a single-curvature curved section, and the heating trajectory corresponding to this single-curvature curved section is a single-curvature curve. The heating mechanism 10 is located on the side of the single-curvature curved section that is relatively far from its curvature center. The heating execution position is located on the side of the single-curvature curved section that is relatively far from its curvature center, and the heating execution position and the retraction avoidance position are also located on the side of the single-curvature curved section that is relatively far from its curvature center. This arrangement can reduce the scorching of the heated section 211 and other parts of the conveyor line 21 outside the heated section 211 by the heat flow.
[0052] Preferably, in this embodiment, the heated section 211 is arc-shaped, and the heated trajectory is an arc-shaped trajectory. The heating mechanism 10 is located outside the heated section 211 on the side relatively away from its center. The feed drive unit 13 drives the heat release unit 11 to extend or retract radially along the heated trajectory, thereby switching between the heating position and the retraction avoidance position. Both the heated trajectory and the extension / retraction trajectory of the heat release unit 11 are parallel to the horizontal plane.
[0053] Of course, in other embodiments, the heated section 211 may also take other shapes, such as an arc or an elliptical arc, or the heated section 211 may also be a straight line segment, and the corresponding heating trajectory is a straight line trajectory.
[0054] Furthermore, when the feed drive unit 13 drives the heat release unit 11 to the heating position, the centerline of the heat outlet 111 of the heat release unit 11 coincides with the instantaneous heating tangent of the heating trajectory. The instantaneous heating tangent refers to a virtual tangent line that is tangent to the heating trajectory, with the tangency point being a point on the heating trajectory that passes through the heat outlet 111. The extension direction of the instantaneous heating tangent line is the instantaneous velocity direction of the aforementioned marked tracking point when it passes through the heat outlet 111. The centerline of the heat outlet 111 represents the opening angle of the heat outlet 111, which is equivalent to the initial velocity direction of the heat released from the heat outlet 111. This direction does not point towards the conveyor line 21 or the material carrier 22.
[0055] Please refer to it again. Figures 1 to 2 In this embodiment, the material carrier 22 includes a carrier body 221 that is responsively connected to the conveyor line 21 and can move along with the conveyor line 21, and a material carrying assembly 223 installed on the carrier body 221. The material carrying assembly 223 includes a first material fixing member 2231 and a second material fixing member 2232 arranged side by side on the side of the carrier body 221 away from the conveyor line 21. There is a gap between the two, and they can fix the same medical consumable 200. The side-by-side direction of the two is consistent with the axis of the needle / tube.
[0056] Specifically, the first material fixing member 2231 and the second material fixing member 2232 together define a positioning reference. Their function is to fix the axis of the needle / tube relative to the positioning reference when the medical consumable 200 is connected to the first material fixing member 2231 and the second material fixing member 2232, thereby defining the radial position of the medical consumable 200 relative to the material carrying assembly 223. When the heat release section 11 is in the heating position, the positions of the heat outlet 111 and the air outlet side 112 in the direction extending from the positioning reference—that is, the positions of the heat outlet 111 and the air outlet side 112 in the direction extending from the needle / tube axis—are between the positions of the first material fixing member 2231 and the second material fixing member 2232 in this direction.
[0057] Optionally, one of the first material fixing member 2231 and the second material fixing member 2232 is used to fix the tube body, and the other is used to fix the needle. After the medical consumable 200 is fixed and clamped by the material carrying assembly 223, the part to be bonded is located between the first material fixing member 2231 and the second material fixing member 2232. This means that the position of the part to be bonded in the positioning reference extension direction is between the position of the first material fixing member 2231 in this positioning reference extension direction and the position of the second material fixing member 2232 in this positioning reference extension direction. Therefore, the heating trajectory passes through the space between the first material fixing member 2231 and the second material fixing member 2232.
[0058] Specifically, in this embodiment, the positioning reference extends vertically. The first material fixing member 2231 and the second material fixing member 2232 are arranged side by side in the vertical direction and are respectively fixedly connected to the needle and the tube. The needle tip points vertically upward and the needle is higher than the tube, so that the medical consumable 200 carried on the material carrier 22 extends vertically. The feed drive unit 13 horizontally drives the heat release unit 11 to extend or retract. When the heat release unit 11 reaches the heating position, its air outlet side 112 and heat outlet 111 are higher than the second material fixing member 2232 but lower than the first material fixing member 2231 in the vertical direction, and the heating trajectory is parallel to the horizontal plane. The arrangement of this embodiment can also significantly reduce the space required by the heating device 100 in the vertical direction. Whether the conveyor line 21 transports the medical consumable 200 or the heat release unit 11 reaches or leaves the heating position, it is all done in the horizontal direction, and the safety of the heating device 100 is improved.
[0059] It is understood that the above arrangement is not the only way to achieve the purpose of this invention. In other embodiments, the first material fixing member 2231 and the second material fixing member 2232 can also be arranged side by side in the horizontal direction, and the positioning reference extends in the horizontal direction, so that the medical consumable 200 carried on the material carrier 22 extends in the horizontal direction. Correspondingly, the feed drive unit 13 drives the heat release unit 11 to reach or leave its heating position in the radial direction of the tube or needle. To better adapt to this embodiment, the feed drive unit 13 drives the heat release unit 11 to extend or retract in the vertical direction.
[0060] Furthermore, in this embodiment, there are multiple heat release sections 11, which are arranged in groups on the same side of the heating section 211. Each heat release section 11 can be synchronously driven to the heating position by the feed drive unit 13. When one or more groups of heat release sections 11 are in their respective heating positions, the multiple heat release sections 11 in any group are arranged in a row along the tangential direction of the heating trajectory. For any group of heat release sections 11 arranged in a row, there is a material placement gap 12 between every two adjacent heat release sections 11. The heat flow channel of each heating mechanism 10 passes through the two opposite air outlet sides 112 of the heat release section 11 of the heating mechanism 10 to form two heat flow outlets 111, and the multiple heat flow outlets 111 are connected through the material placement gaps 12. When multiple heat release sections 11 reach the heating position, the material placement gap 12 can accommodate a medical consumable 200, and the same heat release section 11 can simultaneously output heat to two medical consumables 200 located next to the two air outlet sides 112 of the heat release section 11 through its two heat outlets 111.
[0061] Correspondingly, in this embodiment, the material carrier 22 includes a plurality of material carrier components 223 arranged at intervals. The arrangement of the plurality of material carrier components 223 is the same as that of the heat release section 11. They can be arranged in rows at intervals, or they can be arranged in groups with each group of material carrier components 223 arranged in rows at intervals. Each material carrier component 223 is fixedly loaded with a medical consumable 200 through its first material fixing member 2231 and second material fixing member 2232. The interval between two adjacent material carrier components 223 is greater than or equal to the distance between the two air outlet sides 112 of the heat release section 11.
[0062] Specifically, in this embodiment, the centerlines of the heat outlets 111 of the plurality of heat release sections 11 coincide and extend horizontally. If the heat release section 11 releases heat through the heat outlet 111, the initial release direction of the heat is tangent to the heating trajectory.
[0063] Optionally, when the heating section 211 adopts a straight conveying section and the heating trajectory is a straight segment trajectory, when the multiple heat release sections 11 reach the heating execution position, these heat release sections 11 can also be arranged along the extension direction of the heating trajectory, and the heating trajectory passes through the heat outlet 111 of each heat release section 11.
[0064] like Figure 1As shown, in order to save on the number of heating mechanisms 10, in this embodiment, a set of material carriers 22 includes six material carrier components 223 that are spaced apart from each other and arranged in rows; each set of heating mechanisms 10 includes three heat release parts 11 arranged in rows. The first heat release part 11 passes through the gap between the first and second material carrier components 223 to reach the heating position, the second heat release part 11 passes through the gap between the third and fourth material carrier components 223 to reach the heating position, and the third heat release part 11 passes through the gap between the fifth and sixth material carrier components 223 to reach the heating position.
[0065] It is understood that in other embodiments, the number of material-carrying components 223 included in a set of material carriers 22 is not limited to six, and similarly, the number of heat release parts 11 in a set of heating mechanisms 10 is not limited to three. According to the number rule of material-carrying components 223 / heat release parts 11 in this embodiment, when there are one or more sets of material carriers 22, and each set of material carriers 22 includes an even number of material-carrying components 223 arranged in rows and spaced apart from each other, the number of individual components of the heat release parts 11 arranged in rows in a set of heating mechanisms 10 can be at least half the number of individual components in a set of material-carrying components 223. If we assume that the total number of individual components of the heat release parts 11 arranged in rows in a set of heating mechanisms 10 is M, then the total number of individual components of the material-carrying components 223 in a set of material carriers 22 is 2M. The Nth heat release part 11 passes through the gap between the (2N-1)th and 2Nth material-carrying components 223 and reaches its heating position, where N < M.
[0066] It is worth noting that the above description of the arrangement of the heating mechanism 10 is not the only way to achieve the purpose of this invention. In some other embodiments, the multiple heat release parts 11 may also be arranged in a continuous row outside one side of the heated section 211, without grouping. In addition, the arrangement of the multiple heat release parts 11 does not necessarily follow this limitation: that is, after the multiple heat release parts 11 reach the heating position, they are arranged in a row along the tangential direction of the heating trajectory. The multiple heat release parts 11 may also extend along the curve of the heating trajectory. For example, when the heating trajectory is arc-shaped, the multiple heat release parts 11 may also be arranged along an arc concentric with the heating trajectory.
[0067] Furthermore, in one embodiment not shown in the figure, the heating mechanism 10 further includes a follow-up drive unit, which can drive the heat release unit 11, which has reached the heating position, to follow the medical consumable 200 along a preset follow-up trajectory. The follow-up trajectory and the heating trajectory at least partially overlap. If the common part of the follow-up trajectory and the heating trajectory is defined as the overlapping trajectory, then during the period when the heat release unit 11 moves along the overlapping trajectory, the heat release unit 11 remains relatively stationary with respect to the material carrier 22 and the medical consumable 200. After the medical consumable leaves the heating section 211, the feed drive unit 13 drives the heat release unit 11 to retract.
[0068] The effect of setting up a follow-up drive unit is that it can extend the heating time of the medical consumable 200, thereby ensuring the heating effect of the part to be bonded, and thus ensuring sufficient overflow of adhesive. Especially for medical consumables 200 with large parts to be bonded and large amount of adhesive applied, the heat release unit 11 follows the medical consumable 200 through the heating section 211, so that the medical consumable 200 will not experience a significant drop in temperature for a longer period of time. In addition, setting up a follow-up drive unit can also shorten the heating cycle of the medical consumable 200 and shorten the downtime of the conveyor mechanism 20. After the conveyor line 21 carries the material carrier 22 to the heating station, it pauses to wait for the heat release unit 11. As soon as the heat release unit 11 reaches the heating position, the conveyor line 21 can immediately resume operation, significantly shortening the downtime.
[0069] In some embodiments, the material carrier 22 further includes a plate 222 made of a heat-resistant material, and the rigidity and strength of the plate 222 do not decrease significantly after being heated. The purpose of providing the plate 222 is to increase the surface area of the material carrier 22, which helps to accelerate the dissipation of the accumulated heat of the material carrier 22 and prevent the material carrier 22 from overheating and being damaged.
[0070] Optionally, the plate 222 is movably connected to the conveyor line 21, and the carrier body 221 is movably installed on the conveyor line 21 via the plate 222. The plate 222 is also provided with a hollow hole.
[0071] See Figure 3 , Figure 3In the illustrated embodiment, the heating device 100 further includes a heat dissipation mechanism 30, which includes a heat flow hood assembly 31. The heat flow hood assembly 31 has a receiving space 313, which can at least accommodate the heat flow release portion 11 of the heating mechanism 10 at some point. Furthermore, the heat flow hood assembly 31 has a first opening 311 on its side relatively close to the heated section 211, and the receiving space 313 communicates with the outside of the heat flow hood assembly 31 through the first opening 311. In this embodiment, when the heat flow release portion 11 is in its retracted avoidance position, it is entirely located within the receiving space 313. The feed drive unit 13 can drive the heat flow release portion 11 to pass through the first opening 311, leave the receiving space 313, and reach the heating execution position. Then, it drives the heat flow release portion 11 to pass through the first opening 311 again, re-enter the receiving space 313, and reach the retracted avoidance position.
[0072] Furthermore, the heat hood assembly 31 also has a second opening 312. The location of the second opening 312 is not specifically limited, as long as it is not located on the same side of the heat hood assembly 31 as the first opening 311, that is, the second opening 312 does not face the heated section 211. In addition, the heat dissipation mechanism 30 also includes an airflow generating component connected to the heat hood assembly 31. After the airflow generating component is activated, it can drive the gas in the accommodating space 313 to flow through the second opening 312 and leave the heat hood assembly 31, thereby allowing the heat in the accommodating space 313 to be carried away by the air and preventing overheating inside.
[0073] Furthermore, a heat flow shield 32 is provided on the side of the heat flow hood assembly 31 facing away from the accommodating space 313. The heat flow shield 32 has higher heat dissipation efficiency, and its installation can prevent personnel from being burned by the surface of the heat flow hood assembly 31. To accelerate the heat dissipation of the heat flow shield 32 and the heat flow hood assembly 31, multiple perforations are provided on the heat flow shield 32. To prevent the heat flow shield 32 from being heated by the heat flow hood assembly 31, there is a gap between the heat flow shield 32 and the heat flow hood assembly 31, preventing heat conduction.
[0074] Optionally, in some embodiments, the heat flow hood assembly 31 can move in response to the power of the feed drive unit 13. When the heat flow release unit 11 moves towards the heating position, the heat flow hood assembly 31 also moves relatively closer to the heated section 211 to accommodate the material carrier 22, the medical consumable 200, and the heat flow release unit 11 in the heating position within the receiving space 313; when the heat flow release unit 11 moves towards the retraction position, the heat flow hood assembly 31 also moves relatively away from the heated section 211. To achieve this technical solution, the heat flow hood assembly 31 can be responsively connected to the power output end of the feed drive unit 13 and remain relatively fixed to the heat flow release unit 11, thus allowing the heat flow release unit 11 to be accommodated in the receiving space 313 at any time.
[0075] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0076] Those skilled in the art should recognize that the above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Any appropriate changes and variations made to the above embodiments within the essential spirit of the present invention fall within the scope of protection claimed by the present invention.
