Abstract
Description
Technical Field
[0001] The invention relates to the technical field of plastic connection, in particular to an automatic connection device for laryngeal mask production. Background Art
[0002] The laryngeal mask airway, also known as the laryngeal mask, was invented by a British anesthesiologist in the early 1980s and was officially approved by the US FDA and entered the market in 1991. The laryngeal mask has the advantages of easy insertion, high blind insertion success rate, little effect on hemodynamics, and few complications, and is becoming increasingly mature in clinical application.
[0003] The structure of the laryngeal mask is mainly composed of a ventilation tube, an air bag and an inflation tube. The air bag can be divided into a circular air bag body and a concave air bag bottom. In the production process of the laryngeal mask, the air bag body and the air bag bottom are produced separately, and then the two are connected, and glue is applied to the connection for bonding, and vulcanized in a high temperature and high humidity environment to finally obtain the air bag product.
[0004] Since the inner edge of the bladder and the bladder bottom in the airbag are bonded together, there is a risk of glue falling off during the use of the laryngeal mask, which may cause harm to the human body if it falls into the patient's mouth. With the iteration of technology, a technology that uses hot melting to connect the bladder and the bladder bottom in the airbag has appeared in the market. After searching, it was found that the patent number is CN111660570B, and the patent name is a laryngeal mask, hot melting welding method and hot melting welding equipment, which records the technical content. The technology is to use two molds to press and hot melt the overlapping part of the inner edge of the bladder and the upper surface of the bladder bottom in the airbag to achieve the airbag connection of the laryngeal mask. In the process of completing the connection between the bladder and the bladder bottom in the airbag, the mold and the connection position of the bladder and the bladder bottom in the airbag may stick to each other, which will make demolding difficult. In addition, since the connection position of the bladder and the bladder bottom in the airbag is unstable after the connection is just completed, forced demolding will cause the risk of tearing at the connection position of the bladder and the bladder bottom, affecting the quality of the airbag in the laryngeal mask after connection.

[0033] In this embodiment, the upper even blocks 62 and the upper odd blocks 63 are staggered with the upper top bar 61 on the circumferential outer wall of the upper rotating rod 6 ; the upper even blocks 62 and the upper odd blocks 63 transition to the upper top bar 61 through the upper transition blocks 64 .
[0034] In this embodiment, the lower surface of the lower mold 5 is provided with a first placement cavity 51 and a second placement cavity 52; the lower mold 5 is composed of a plurality of lower sub-molds 53 distributed laterally; the adjacent lower sub-molds 53 are in sliding and sealing contact; the upper surface of the machine base 1 is provided with a lower slide hole 11; a lower slide rod 12 is slidably connected in the lower slide hole 11; the lower end of the lower slide rod 12 is connected to the bottom of the lower slide hole 11 by a lower tension spring 13; the upper end of the lower slide rod 12 is fixedly connected to the corresponding lower sub-mold 53; the same lower sub-mold 53 is connected to two lower slide rods 12; the upper surface of the machine base 1 is provided with a A lower rotating groove 14; a lower motor 15 is fixedly connected to the lower rotating groove 14; an output shaft of the lower motor 15 is fixedly connected to the lower rotating rod 7; a lower top bar 71 is axially arranged on the outer wall of the lower rotating rod 7; the lower top bar 71 spans across a plurality of lower sub-moulds 53; a plurality of lower even blocks 72 and a plurality of lower odd blocks 73 are axially arranged on the outer wall of the lower rotating rod 7; the lower top bar 71, the lower even blocks 72 and the lower odd blocks 73 can extend out of the lower rotating groove 14 when the lower rotating rod 7 rotates; the lower even blocks 72 are located directly below the lower sub-moulds 53 at the even positions in the lateral direction; the lower odd blocks 73 are located directly below the lower sub-moulds 53 at the odd positions in the lateral direction.
[0035] In this embodiment, the lower even blocks 72 and the lower odd blocks 73 are staggered with the lower top bar 71 on the circumferential outer wall of the lower rotating rod 7 ; the lower even blocks 72 and the lower odd blocks 73 transition to the lower top bar 71 through the lower transition blocks 74 .
[0036] In this embodiment, the lower odd blocks 73 flip upwards while the upper odd blocks 63 flip downwards; and the lower even blocks 72 flip upwards while the upper even blocks 62 flip downwards.
[0037] In the initial state, the lower motor 15 rotates to drive the lower rotating rod 7 to rotate. During the rotation of the lower rotating rod 7, the lower top bar 71 of the outer wall will be driven to rotate, so that the lower top bar 71 will flip toward the outside in the lower rotating groove 14, and the lower top bar 71 will squeeze all the lower sub-die molds 53 to move upward during the upward flipping process. The lower sub-die mold 53 will drive the lower slide bar 12 to move upward during the upward movement. The lower slide bar 12 will slide and move upward in the lower slide hole 11 during the upward movement. The corresponding lower tension spring 13 will be pulled during the upward movement of the lower slide bar 12, and the lower slide bar 12 will not separate from the lower slide hole 11. After all the lower sub-die molds 53 are pushed upward by the lower top bar 71, a movable gap is formed between the lower surface of the lower sub-die mold 53 and the upper surface of the machine base 1, thus completing the preparation work of the lower die 5. ; Then, the bag bottom in the laryngeal mask airbag is placed in the first placement cavity 51, and the second placement cavity 52 is located on the outside of the first placement cavity 51 and is annular. After the bag bottom is placed in the first placement cavity 51, the upper port of the bag bottom is turned outward and falls on the upper port of the first placement cavity 51, and then the annular bag body in the laryngeal mask airbag is placed in the second placement cavity 52, and the annular connecting piece on the inner side of the bag body will fall on the upper port of the bag bottom, and the annular connecting piece and the upper port of the bag bottom are partially overlapped, and then the upper motor 35 will drive the upper rotating rod 6 to rotate, and the upper rotating rod 6 will drive the upper top bar 61 to flip downward during the rotation process, and the upper top bar 61 will squeeze the upper sub-mold 42 during the downward flipping process, and the upper surface of the upper sub-mold 42 will be pressed The entire upper mold 4 will move downward, and the upper sub-mold 4 During the downward movement, the upper slide rod 32 will be driven to slide in the upper slide hole 31 and pull the upper tension spring 33. The upper slide rod 32 will not be separated from the upper slide hole 31. After all the upper split molds 42 are pushed downward by the upper top bar 61, a movable gap is formed between the upper surface of the upper split mold 42 and the lower surface of the upper seat 3, thus completing the preparation of the upper mold 4; then the electric push rod 21 will drive the upper seat 3 to move downward. The electric push rod 21 can be replaced by a telescopic component such as a hydraulic cylinder. During the downward movement of the upper seat 3, the upper rotating rod 6 and the upper motor 35 will be driven downward. During the downward movement of the upper seat 3, the upper mold 4 pushed up by the upper top bar 61 will also be driven downward. During the downward movement of the upper mold 4, the pressing part 41 will be driven to move toward the inner side of the capsule until the pressing part 41 of the upper mold 4 is The annular connecting piece is pressed tightly, so that the annular connecting piece on the inner side of the capsule and the upper port of the capsule are clamped between the upper mold 4 and the lower mold 5. Then the high-frequency source works, the pressing part 41 on the lower surface of the upper mold 4 is the positive electrode, and the upper port position of the first placement cavity 51 of the lower mold 5 is the negative electrode. The high-frequency electromagnetic field is generated by the high-frequency source, and the object to be processed made of dielectric material is pressed between the positive and negative electrodes of the high-frequency electromagnetic field. Under the action of the high-frequency electric field, the dielectric material undergoes molecular polarization and is arranged in the direction of the electric field. Because the high-frequency electric field changes direction at a very fast speed, the internal molecules in the dielectric material are excited and move at a high speed to rub against each other and generate heat, thereby achieving the purpose of welding. After the welding is completed, wait for cooling and solidification to form;
[0038] Then, demoulding begins. Before demoulding, the upper motor 35 drives the upper rotating rod 6 to rotate. During the rotation of the upper rotating rod 6, the upper top bar 61 is driven to flip upward. During the rotation of the upper rotating rod 6, the upper even-numbered blocks 62 are driven to flip downward. Since the upper even-numbered blocks 62 transition to the upper top bar 61 through the upper transition block 64, under the transition of the upper transition block 64, the upper even-numbered blocks 62 flip downward to replace the position of the upper top bar 61. The width of the upper even-numbered blocks 62 in the lateral direction does not exceed the width of the upper sub-mold 42. 62 can make the upper sub-mold 42 of the even number position press against the interface position of the airbag without changing the position, and the upper sub-mold 42 of the odd number position drives the corresponding upper slide bar 32 to move upward under the pull of the corresponding upper tension spring 33, and the upper sub-mold 42 of the odd number position is separated from the contact with the airbag interface after moving up, so as to release the bonding between the upper sub-mold 42 of the odd number position and the airbag interface. Since the upper sub-mold 42 of the even number position presses against the airbag interface during the upward movement of the upper sub-mold 42 of the odd number position, the airbag interface is fixed. The lower even-numbered blocks 72 are pressed tightly, so that the upper sub-molds 42 of the odd-numbered positions can be smoothly separated from the bonding without damaging the airbag interface; during the downward flipping of the upper even-numbered blocks 62, the lower motor 15 synchronously drives the lower rotating rod 7 to rotate, and the lower rotating rod 7 synchronously drives the lower even-numbered blocks 72 to flip upward, and the lower even-numbered blocks 72 will replace the lower top strip 71 to abut against the lower surface of the lower sub-mold 53. After the lower even-numbered blocks 72 abut against the lower surface of the lower sub-mold 53 through the lower transition block 74, the upper even-numbered blocks 62 abut against the upper sub-mold 4 2 upper surface, to achieve the clamping of the airbag interface position, and the lower odd-numbered block 73 will slide in the lower slide hole 11 under the pull of the corresponding lower tension spring 13, so that the lower odd-numbered block 73 moves downward and separates from the airbag interface under the pull, so that the lower odd-numbered block 73 and the upper odd-numbered block 63 are synchronously separated from the airbag interface and released from the bonding. Since the airbag interface has been solidified and formed, the upper sub-mold 42 and the lower sub-mold 53 at the odd position will not form adhesion again when they contact the airbag interface position again after releasing the bonding;
[0039] After the upper sub-mold 42 and the lower sub-mold 53 at the odd-numbered positions are released from the bonding with the airbag interface, the upper rotating rod 6 and the lower rotating rod 7 will rotate synchronously in opposite directions, and the upper rotating rod 6 will drive the upper odd-numbered block 63 to flip downward, and the upper even-numbered block 62 will flip upward during the process of the upper odd-numbered block 63 flipping downward, until the upper odd-numbered block 63 flips to the lower limit position, and the upper odd-numbered block 63 will press the upper sub-mold 42 at the odd-numbered positions against the airbag interface position, and the upper sub-mold 42 at the even-numbered positions will move upward under the pulling of the corresponding upper tension spring 33, so as to release the bonding between the upper sub-mold 42 and the airbag interface position of the even-numbered positions, and during the rotation of the upper rotating rod 6, the lower rotating rod 7 will drive the lower odd-numbered block 73 to flip upward, and the lower even-numbered block 72 will flip downward during the process of the lower odd-numbered block 73 flipping upward, until the lower odd-numbered block 73 flips to the upper limit position, and the lower odd-numbered block 73 will press the upper sub-mold 42 at the odd-numbered positions against the airbag interface position. The lower sub-mold 53 of the even-numbered position is pressed against the airbag interface position, and the lower sub-mold 53 of the even-numbered position is pulled downward by the corresponding lower tension spring 13, so that the lower sub-mold 53 of the even-numbered position is debonded from the airbag interface position. In the process of the upper sub-mold 42 of the even-numbered position and the lower sub-mold 53 of the even-numbered position being separated from the airbag interface, the upper sub-mold 42 of the odd-numbered position and the lower sub-mold 53 of the odd-numbered position are pressed against the airbag interface position, so that the pulling damage of the airbag interface position will not be caused during the debonding process, and a good debonding process is achieved; finally, the upper rotating rod 6 presses the upper top strip 61 against the upper sub-mold 42, and the lower rotating rod 7 presses the lower top strip 71 against the lower sub-mold 53, and then the electric push rod 21 is directly controlled to shorten, and the electric push rod 21 will drive the upper seat 3 to move upward, and the upper seat 3 will drive the upper mold 4 to move upward and separate from the airbag, so that the airbag can be directly removed after being exposed;
[0040] The present invention controls the upper and lower sub-molds 42 and 53 of odd and even numbers to separate from the airbag interface position before demoulding, thereby debonding the airbag interface position when it is clamped, thereby ensuring that the subsequent airbag can be demoulded smoothly without sticking to the mold.
[0041] Embodiment 2: The front sides of the upper split molds 42 at odd-numbered positions laterally downward are fixedly connected to the upper front connecting strip 43 ; the rear sides of the upper split molds 42 at even-numbered positions laterally downward are fixedly connected to the upper rear connecting strip 44 .
[0042] In this embodiment, the front sides of the lower sub-molds 53 at the odd-numbered positions facing downward are commonly fixedly connected to the lower front connecting strip 54 ; the rear sides of the lower sub-molds 53 at the even-numbered positions facing downward are commonly fixedly connected to the lower rear connecting strip 55 .
[0043] After the airbag interface position is pressed tightly by the even-numbered upper sub-mold 42 and the lower sub-mold 53, the upper tension spring 33 will pull the odd-numbered upper sub-molds 42 to move upward. Since the front sides of the odd-numbered upper sub-molds 42 are commonly fixedly connected to the upper front connecting strip 43, all the odd-numbered upper sub-molds 42 will move upward synchronously, and the odd-numbered upper sub-molds 42 will move upward synchronously to separate from the airbag interface. The adhesion between the airbag interface and the upper sub-mold 42 at the contact position is not the same. For some upper sub-molds 42 with smaller adhesion, they can be quickly moved upward to achieve debonding under the pull of the corresponding upper tension spring 33, while for some upper sub-molds 42 with larger adhesion, it is more difficult to debond. By connecting the upper front connecting strip 43, the odd-numbered upper sub-molds 42 are connected as a whole, so that the odd-numbered upper sub-molds 42 can be assembled The odd-numbered upper pull springs 33 work together to achieve upward movement, ensuring the efficiency and effect of debonding the odd-numbered upper sub-molds 42; similarly, after the airbag interface position is pressed tightly by the even-numbered upper sub-molds 42 and the lower sub-molds 53, the lower pull springs 13 will also pull the odd-numbered lower sub-molds 53 to move downward synchronously, so that no matter how different the bonding resistances of the odd-numbered lower sub-molds 53 are, they can move downward smoothly, ensuring the efficiency and effect of debonding the odd-numbered lower sub-molds 53; similarly, after the airbag interface position is pressed tightly by the odd-numbered upper sub-molds 42 and the lower sub-molds 53, the upper pull springs 33 will synchronously pull the even-numbered upper sub-molds 42 to move upward, and the lower pull springs 13 will synchronously pull the even-numbered lower sub-molds 53 to move downward, thus ensuring the efficiency and effect of debonding the even-numbered upper sub-molds 42 and the lower sub-molds 53.
[0044] Embodiment 3: The upper sliding hole 31 is slidably and sealedly connected to the upper sliding rod 32; the upper sliding holes 31 at odd positions are penetrated upward with upper odd holes 36; the upper sliding holes 31 at even positions are penetrated upward with upper even holes 37; the apertures of the upper odd holes 36 and the upper even holes 37 increase as they move away from the upper mold 4.
[0045] In this embodiment, the lower sliding hole 11 is slidably and sealingly connected to the lower sliding rod 12; the lower sliding holes 11 at odd positions are penetrated downwardly by lower odd holes 16; the lower sliding holes 11 at even positions are penetrated downwardly by lower even holes 17; the apertures of the lower odd holes 16 and the lower even holes 17 increase as they move away from the lower mold 5.
[0046] Since the apertures of the upper odd-numbered holes 36 and the upper even-numbered holes 37 are arranged to increase as they move away from the upper mold 4, external gas can enter the upper sliding hole 31 more quickly during the downward movement of the upper sliding rod 32 in the upper sliding hole 31, and the gas in the upper sliding hole 31 can only be slowly discharged to the outside during the upward movement of the upper sliding rod 32 along the upper sliding hole 31. In this way, the resistance formed by the downward movement of the upper sliding rod 32 in the upper sliding hole 31 is small, and the upward movement speed of the upper sliding rod 32 in the upper sliding hole 31 is slow. On the one hand, this reduces the resistance to the downward movement of the upper sub-mold 42, and on the other hand, it allows the upper sub-mold 42 to detach from the airbag interface position at a slow speed, thereby reducing damage caused by the rapid detachment of the upper sub-mold 42 from the airbag interface, thereby achieving the purpose of further protecting the airbag interface. Similarly, since the apertures of the lower odd-numbered holes 16 and the lower even-numbered holes 17 are arranged to increase as they move away from the lower mold 5, during the process of the lower slide rod 12 moving upward in the lower slide hole 11, the outside gas can enter the lower slide hole 11 faster, and during the process of the lower slide rod 12 moving downward along the lower slide hole 11, the gas in the lower slide hole 11 can only be slowly discharged to the outside, so that the resistance of the lower slide rod 12 moving upward in the lower slide hole 11 is smaller, and the speed of the lower slide rod 12 moving downward in the lower slide hole 11 is slower. In this way, on the one hand, the resistance to the upward movement of the lower sub-mold 53 is reduced, and on the other hand, the lower sub-mold 53 can be separated from the airbag interface position at a slow speed, thereby reducing the damage caused by the rapid separation of the lower sub-mold 53 from the airbag interface, thereby protecting the airbag interface.
