Description

Sintering device and medical instrument production line

Technical Field

The application relates to medical equipment, in particular to a sintering device and a medical equipment production line.

Background

Most medical devices are assembled from multiple components. In the automatic production process of the medical instrument, part of the components need to be sintered. For example, the first component in the dialyzer needs to be end-sintered. The existing sintering device usually adopts an infrared ceramic heating plate to heat a part to be sintered, so as to realize the sintering of the part to be sintered.

The thermal field of the infrared ceramic heating plate is constant and cannot ensure the complete uniformity of the thermal field, so that the components to be sintered cannot be uniformly heated, and a better sintering effect cannot be ensured. Therefore, the existing sintering device usually rotates the part to be sintered to make the part to be sintered heated uniformly.

Meanwhile, during sintering, the part to be sintered may be shortened as sintering proceeds, resulting in an increase in the distance between the part to be sintered and the heating sheet, resulting in a decrease in sintering stability. Therefore, in the existing sintering device, the component to be sintered and the heating sheet need to be controlled to move towards each other during the sintering process, so that the distance between the component to be sintered and the heating sheet is kept unchanged, and the sintering stability is guaranteed. When sintering is required to be performed on both ends of a part to be sintered, the conventional sintering apparatus generally employs a method of controlling the heating sheet to move toward the part to be sintered without rotating, and the part to be sintered to rotate without moving toward the heating sheet.

Therefore, the heating plate and the component to be sintered both need to move, so that the heating plate and the component to be sintered also need corresponding driving structures, and the respective driving structures of the heating plate and the component to be sintered are independent, so that the whole sintering device is not compact enough in structure and needs to be improved.

As used in the description of the present application, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, an embodiment of the present application first provides a sintering apparatus including a frame 100, a positioning assembly 200, a heating assembly 300, and a sintering driving assembly 400. Both the positioning assembly 200 and the sinter drive assembly 400 are mounted on the frame 100. The material includes a first component part and a second component part 500. The second part 500 is wrapped around the first part with both ends of the first part exposed from both ends of the second part 500, respectively. When the material is a dialyzer, the first component is a fiber bundle and the second component 500 is a housing. The positioning assembly 200 is used for positioning the first component part and the second component part 500, and the heating assembly 300 is used for heating the end part of the first component part exposed out of the second component part 500. When the heating assembly 300 heats the end portion of the first component exposed to the second component 500, the sintering driving assembly 400 drives the heating assembly 300 to move relative to the material, and the material positioned by the positioning assembly 200 is stationary relative to the frame 100.

Referring to fig. 2, the positioning assembly 200 includes a supporting member 210, a first positioning member 220, a second positioning member 230, a linkage member 240, a positioning driving member 250, and an alignment driving member 260. Wherein, the number of the supporting members 210 is provided with two, and the number of the first positioning members 220 is provided with two. The two supporting members 210 abut against the lower side of the second component 500 to support the second component 500. The first positioning member 220, the supporting member 210, the second positioning member 230, the supporting member 210 and the first positioning member 220 are sequentially distributed along the axial direction of the second component part 500. Both the first positioning member 220 and the second positioning member 230 are connected to the link member 240. The positioning driving member 250 drives the link member 240 to move so as to simultaneously drive the two first positioning members 220 and the second positioning member 230 to move. The link 240 is provided to enable the two first positioning members 220 and the second positioning member 230 to be simultaneously moved by the positioning driving member 250, thereby reducing the number of the positioning driving members 250. The first positioning member 220 is used to position a portion of the first component part exposed from an end of the second component part 500. The second positioning member 230 is used for positioning the second component 500, so that the second positioning member 230 can also support the second component 500. Specifically, the first positioning member 220 includes a left jaw and a right jaw. The left and right jaws embrace the end portion of the first component exposed from the second component 500 to position the first component from the end exposed portion of the second component 500. The second positioning member 230 is similar to the first positioning member 220, and also surrounds the second component 500 by using a similar structure, so as to position the second component 500. The positioning driving member 250 drives the first positioning member 220 and the second positioning member 230 to position the end portion of the first component exposed from the second component 500 and the second component 500, respectively. The positioning driving member 250, the supporting member 210 and the alignment driving member 260 are connected, and the alignment driving member 260 drives the supporting member 210 and the alignment driving member 260 to move until the end portion of the first component exposed out of the second component 500 is aligned with the heating assembly 300. If only the first positioning element 220 is disposed and the second positioning element 230 is not disposed, the second positioning element 230 may apply a force to the first component during the sintering process, so that the first component is easily damaged, and under the influence of the second component 500, the length of the end portion of the first component, which is exposed out of the second component 500, of the first component positioned by the first positioning element 220 is changed, thereby affecting the sintering effect. If only the second positioning member 230 is disposed and the first positioning member 220 is not disposed, the end portion of the first component exposed from the second component 500 cannot be effectively positioned, so that the heating assembly 300 does not start to heat from the end of the first component, thereby affecting the sintering effect. Therefore, the end portion of the first component part exposed to the second component part 500 and the second component part 500 are positioned by the first positioning member 220 and the second positioning member 230, respectively, thereby securing the sintering effect.

Referring to fig. 3, the heating assembly 300 includes at least two heating sheets 310. The plurality of heating plates 310 are respectively located at both ends of the material in the axial direction, so that the first component parts exposed from both ends of the second component part 500 can be sintered, respectively. The sintering drive assembly 400 includes two translation drives 410 and two rotation drives 420. The two translational drivers 410 and the two rotational drivers 420 correspond one to one. The translation drives 410 are coupled to the corresponding rotation drives 420 such that the translation drives 410 are capable of driving the rotation drives 420 to translate. The two translational driving members 410 are respectively located at two axial ends of the material, and the two rotational driving members 420 are correspondingly respectively located at two axial ends of the material. The two rotation driving members 420 are respectively connected to the heating plates 310 located at the same axial end of the material, so that the rotation driving members 420 can drive the connected heating plates 310 to rotate relative to the material. When the heating plate 310 rotates relative to the material, the heating plate 310 rotates around the axis of the material and the axis of the heating plate 310 coincides with the axis of the material. Meanwhile, the two rotary driving members 420 can drive the connected heating plates 310 to translate towards the material under the action of the corresponding translation driving members 410. If the sintering driving assembly 400 is used to drive the material to move relative to the heating assemblies 300 and the heating assemblies 300 are stationary relative to the frame 100, when both ends of the material need to be sintered, one end of the material moves towards the corresponding heating assembly 300 so that the distance between the end of the material and the corresponding heating assembly 300 remains unchanged, but the distance between the other end of the material and the corresponding heating assembly 300 increases, and thus the stability of sintering at both ends of the material cannot be guaranteed at the same time. Therefore, both ends of the material can be heated only in steps by the heating assembly 300. However, the efficiency of the material processing is significantly reduced. Therefore, the sintering driving assembly 400 is adopted to drive the heating assembly 300 to move relative to the material, and the material positioned by the positioning assembly 200 is static relative to the rack 100, so that the stability and uniformity of sintering at two ends of the material can be ensured simultaneously, and the processing efficiency is improved. When the heating assembly 300 heats the material, the relative movement and the relative rotation of the heating assembly 300 and the material are unified to one of the heating assembly 300 and the material, so that the whole sintering device is more compact.

The working process comprises the following steps:

after the heating plate 310 is preheated to the set temperature, the material is placed on the support 210. Subsequently, the alignment driving member 260 drives the supporting member 210 to move to the end portions of the first component part exposed to the second component part 500 to be aligned with the corresponding heating sheets 310 respectively. At the same time, the positioning driving member 250 is also moved by the alignment driving member 260. After the end portions of the two ends of the first component exposed to the second component 500 are aligned with the corresponding heating sheets 310, the positioning driving member 250 drives the linking member 240 to move, so that the linking member 240 drives the two first positioning members 220 and the second positioning member 230 to move, the two first positioning members 220 surround the end portions of the two ends of the first component exposed to the second component 500, and the second positioning member 230 surrounds the second component 500.

The two translational drives 410 respectively drive the corresponding rotational drives 420 to perform translational motion. While the two rotation drivers 420 drive the connected heating sheets 310 to move towards the end portion of the first component exposed out of the second component 500, the two rotation drivers 420 respectively drive the connected heating sheets 310 to rotate, and finally sintering of the end portion of the first component exposed out of the second component 500 is achieved.

Embodiments of the present application additionally provide a medical instrument production line including the above sintering apparatus. The medical instrument production line adopting the sintering device has compact structure and lower cost.

It is understood that two positioning actuators 250 are contemplated, wherein one positioning actuator 250 drives the first positioning member 220 and the other positioning actuator 250 drives the second positioning member 230. At this time, the link 240 also does not need to be provided.

It is understood that the supporting member 210 may be eliminated and the position of the second positioning member 230 may be adjusted to be below the second component part 500, so that the second positioning member 230 can support the second component part 500. The positioning assembly 200 further includes auxiliary positioning members, the auxiliary positioning members and the second positioning member 230 being located on opposite sides of the second component 500. The auxiliary positioning member and the second positioning member 230 cooperate to position the second component 500.

It is understood that the axis of the heating plate 310 may be parallel to the axis of the material but not coincident with the axis of the material, so long as the first component is uniformly heated by the heating plate 310.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several implementation modes of the present application, and the description thereof is specific and detailed, but not construed as limiting the scope of the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, and these are all within the scope of protection of the present application. Therefore, the protection scope of the present application shall be subject to the appended claims.
