Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment for the production of hemostatic forceps, and specifically to a welding device for the production of hemostatic forceps. Background Art

[0002] Brazing is a commonly used welding method for hemostatic forceps. Before welding, the parts to be welded of the hemostatic forceps need to be carefully cleaned to remove impurities such as oil stains, rust, and oxides on the surface to ensure that the brazing filler metal can wet the base metal well. Appropriate brazing filler metal and brazing flux are selected according to the material of the base metal. The melting point of the brazing filler metal should be lower than that of the base metal to achieve welding at a lower temperature.

[0003] However, during the welding process, due to the influence of the welding environment, impurities such as oxygen and dust in the air will affect the welding quality. Oxygen will form oxides during welding due to the increase in the temperature of the hemostatic forceps. If the moisture in the air is relatively large or the hemostatic forceps are relatively wet, pores will also appear, thus affecting the welding quality. Summary of the Invention

One end of the trapezoidal locking block penetrates through the rectangular limiting plate and is slidably connected to the rectangular limiting plate.

[0014] The present invention has the following beneficial effects:

[0015] (1) For a welding device for producing hemostatic forceps according to the present invention, the hemostatic forceps are placed into the welding box, and then the box door is closed. The vacuum pump is started, and the vacuum pump starts to suck air and draws air into the welding box through the suction pipe. Since the cross chute is not in a closed state at this time, the outside air will enter the welding box under the action of the vacuum pump. During this process, when the air enters the welding box from the cross chute, it will pass through several heating pipes. Under the heating condition, the hot air will dry the hemostatic forceps and other facilities in the welding box, so that the moisture in the welding box is sucked out of the welding box under the action of the vacuum pump. At the same time, the vacuum pump will also suck out the dust and impurities in the welding box, reducing the objective influence of moisture, impurities and dust, preventing the appearance of welding slag and pores during welding. The sucked air will be discharged into the transmission air box through the air outlet pipe. The air will drive the round block to move away from the vacuum pump. The round block will drive the transmission rod to move, and the transmission rod will drive the transmission air box to move. At this time, the closing spring undergoes a compressive deformation. After the dust and impurities in the welding box are sucked out, the transmission air box will close the cross chute at this time, making the welding box form a completely closed state. Since the air in the welding box has not been exhausted at this time and the vacuum pump continues to operate, during the continuous advancement of the round block, it will pass through the exhaust groove. At this time, the closing spring will undergo further compression. As the gas in the transmission air box accumulates more and more, the gas will be discharged from the gap between the round block and the exhaust groove. When the welding box is completely in a vacuum state, the vacuum pump stops operating. Under the elastic force of the closing spring, the round block will move a short distance again in the direction close to the vacuum pump. At this time, the round block will cover the exhaust groove, thereby avoiding air leakage and making the closing plate firmly close the cross chute to maintain the vacuum state in the welding box;

[0016] (2) For a welding device for producing hemostatic forceps according to the present invention, when the transmission rod moves away from the vacuum pump, the transmission rod will drive the L-shaped flat plate to move. The L-shaped flat plate will drive several trapezoidal blocks to touch the L-shaped transmission plate. Under the action of the inclined surface of the trapezoidal block, the trapezoidal block will pass through the L-shaped transmission plate, and the L-shaped transmission plate will move upward. The L-shaped transmission plate will drive the rectangular movable frame to rise. At this time, the dust removal spring undergoes elastic compression. After the trapezoidal block leaves the L-shaped transmission plate, the L-shaped transmission plate will descend under the action of the dust removal spring. During this process, the rectangular movable frame moves up and down reciprocally. The rectangular movable frame will drive several scraping plates to clean the dust and impurities on the surface of the dust-proof filter plate, avoiding the blockage of the filter holes on the dust-proof filter plate by dust and impurities, thereby affecting the smoothness during the air suction of the vacuum pump and weakening the magnitude of the air volume entering the welding box. The magnitude of the air intake volume will affect the drying degree in the welding box;

[0017] (3) For the welding device used in the production of hemostatic forceps of the present invention, during the process of dust removal and air suction of the welding box, since the external gas enters the welding box from the cross chute, and when the air enters the welding box from the cross chute, it will blow towards the box door. Before closing the box door, the hydraulic cylinder needs to be started. The hydraulic cylinder drives the special-shaped plate to descend, the special-shaped plate drives the two rectangular boxes to descend, and the trapezoidal lock blocks in the rectangular boxes will slide out of the welding box under the action of the inclined surface. At this time, the box door and the rectangular limit plate are installed on the welding box, and then the hydraulic cylinder is started again to raise the special-shaped plate. During the rising process of the special-shaped plate, the rectangular rod will drive the rectangular box to rise under the action of the self-locking spring. When the trapezoidal lock block touches the notch on the welding box, the adaptive spring that has been in a compressed state will push the trapezoidal lock block into the welding box and penetrate the rectangular limit plate in the rectangular box. At this time, the fixation of the rectangular limit plate and the box door is completed, avoiding the wind entering the welding box from the cross chute from blowing off the box door or causing the welding box to not be completely sealed.

[0018] (4) For the welding device used in the production of hemostatic forceps of the present invention, after welding is completed, the hydraulic cylinder is started. The hydraulic cylinder drives the special-shaped plate to descend. When the special-shaped plate descends, it will not only push the trapezoidal lock block out of the welding box to unlock the box door, but also drive the L-shaped plate to descend. The L-shaped plate will slide down in the transmission air box. At this time, half of the rectangular groove on the L-shaped plate will be exposed outside the transmission air box and half will be inside the transmission air box. At this time, the air in the transmission air box and the air outlet pipe will be discharged from the rectangular groove. Since there is no gas support for the round block, the closing plate will open the cross chute under the elastic force of several closing springs. At this time, the box door is opened, and the air circulation in the welding box can improve the cooling effect of the hemostatic forceps in the welding box.

[0019] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1 - Figure 8As shown in the figure, the present invention is a welding device for the production of hemostatic forceps, including a welding box 1. A closing mechanism is provided on the welding box 1. The closing mechanism includes a vacuum pump 101 fixedly installed on the back of the welding box 1. An air suction pipe 102 and an air outlet pipe 103 are fixedly installed on the outer wall of the vacuum pump 101. The end of the air suction pipe 102 is fixedly connected to the welding box 1, and the air suction pipe 102 communicates with the welding box 1. A cross-shaped chute 104 is opened in the welding box 1. A number of closing springs 105 are fixedly installed on the right inner wall of the cross-shaped chute 104. It also includes:

[0032] A closing plate 106 is fixedly installed on the left side of a number of closing springs 105. The closing plate 106 is slidably connected to the cross-shaped chute 104. A transmission air box 107 is fixedly installed on the back of the welding box 1. The left end of the transmission air box 107 is fixedly connected to and communicates with the air outlet pipe 103. A round block 108 is slidably installed in the transmission air box 107. A transmission rod 109 is fixedly installed on the right side of the round block 108. The right end of the transmission rod 109 extends outside the transmission air box 107. A strip-shaped groove 110 is opened on the back of the welding box 1. The strip-shaped groove 110 communicates with the cross-shaped chute 104. The transmission rod 109 passes through the strip-shaped groove 110 and is fixedly connected to the closing plate 106.

[0033] As Figure 4 shown, an opening and closing mechanism 2 is provided on the transmission air box 107. The opening and closing mechanism 2 includes an exhaust groove 201 opened on the back of the transmission air box 107. An L-shaped plate 202 is slidably installed in the transmission air box 107. The L-shaped plate 202 penetrates the transmission air box 107. A rectangular groove 203 is opened on the L-shaped plate 202.

[0034] Gas will be discharged from the gap between the round block 108 and the exhaust groove 201. When a completely vacuum state is formed inside the welding box 1, the vacuum pump 101 stops operating. Under the elastic force of the closing springs 105, the round block 108 will move a small distance in the direction closer to the vacuum pump 101 again. At this time, the round block 108 will cover the exhaust groove 201 to prevent air leakage, so that the closing plate 106 steadily closes the cross-shaped chute 104 and maintains the vacuum state inside the welding box 1.

[0035] As Figure 5As shown in the figure, a dust removal mechanism is provided on the back of the welding box 1. The dust removal mechanism includes a rectangular frame 301 fixedly installed on the back of the welding box 1. A dust-proof filter plate 302 is fixedly installed on the back of the welding box 1. A sliding rod 303 is fixedly installed on the inner wall of the top of the rectangular frame 301. A rectangular movable frame 304 is slidably sleeved on the sliding rod 303. The rectangular movable frame 304 is slidably connected to the rectangular frame 301. A dust removal spring 305 is sleeved on the sliding rod 303. The top end of the dust removal spring 305 is fixedly connected to the rectangular frame 301. The bottom end of the dust removal spring 305 is fixedly connected to the rectangular movable frame 304. A plurality of scraping plates 306 are fixedly installed in the rectangular movable frame 304. The sliding rod 303 passes through a plurality of scraping plates 306 and is slidably connected to a plurality of scraping plates 306.

[0036] During this process, the rectangular movable frame 304 moves up and down reciprocally. The rectangular movable frame 304 will drive a plurality of scraping plates 306 to clean the dust and impurities on the surface of the dust-proof filter plate 302, avoiding the dust and impurities from blocking the filter holes on the dust-proof filter plate 302, thereby affecting the smoothness during the air suction of the vacuum pump 101 and weakening the magnitude of the air volume entering the welding box 1. The magnitude of the air intake volume will affect the dryness inside the welding box 1.

[0037] As Figure 5 shown in the figure, a reciprocating mechanism 4 is provided on the back of the rectangular frame 301. The reciprocating mechanism 4 includes an L-shaped transmission plate 401 fixedly installed on the back of the rectangular frame 301. An L-shaped flat plate 402 is fixedly installed on the transmission rod 109. A plurality of trapezoidal blocks 403 are fixedly installed on the top of the L-shaped flat plate 402.

[0038] The transmission rod 109 will drive the L-shaped flat plate 402 to move. The L-shaped flat plate 402 will drive a plurality of trapezoidal blocks 403 to touch the L-shaped transmission plate 401. Under the action of the inclined surface of the trapezoidal block 403, the trapezoidal block 403 will pass through the L-shaped transmission plate 401, and the L-shaped transmission plate 401 will move upward. The L-shaped transmission plate 401 will drive the rectangular movable frame 304 to rise. At this time, the dust removal spring 305 is elastically compressed. After the trapezoidal block 403 leaves the L-shaped transmission plate 401, the L-shaped transmission plate 401 will descend under the action of the dust removal spring 305.

[0039] As Figure 7 shown in the figure, a drying mechanism is provided inside the welding box 1. The drying mechanism includes a heating box 501 fixedly installed inside the welding box 1. A plurality of air outlet holes 502 are opened on the heating box 501. A plurality of heating tubes 503 are fixedly installed inside the heating box 501.

[0040] The outside air will enter the welding box 1 under the action of the vacuum pump 101. During this process, when the air enters the welding box 1 from the cross-shaped chute 104, it will pass through a plurality of heating tubes 503. In the case of heating, the hot air will dry the hemostatic forceps and other facilities inside the welding box 1.

[0041] As Figure 7 shown, a sealing mechanism is provided on the front of the welding box 1. The sealing mechanism includes a box door 601 provided on the front of the welding box 1. A rectangular limiting plate 602 is fixedly installed on the back of the box door 601. The end of the rectangular limiting plate 602 extends into the welding box 1 and is slidably connected to the welding box 1.

[0042] The trapezoidal locking block 805 is inserted into the welding box 1 and penetrates through the rectangular limiting plate 602. At this time, the rectangular limiting plate 602 and the box door 601 are fixed, preventing the wind entering the welding box 1 from the cross chute 104 from blowing the box door 601 off or causing the welding box 1 to not be completely sealed.

[0043] As Figure 2 shown, a driving mechanism 7 is provided on the welding box 1. The driving mechanism 7 includes a U-shaped mounting plate 701 fixedly installed on the top of the welding box 1. A hydraulic cylinder 702 is fixedly installed on the bottom inner wall of the U-shaped mounting plate 701. A special-shaped plate 703 is fixedly installed on the output shaft of the hydraulic cylinder 702. The front of the L-shaped plate 202 is fixedly connected to the special-shaped plate 703.

[0044] After welding is completed, the hydraulic cylinder 702 is started. The hydraulic cylinder 702 drives the special-shaped plate 703 to descend. When the special-shaped plate 703 descends, it will not only push the trapezoidal locking block 805 out of the welding box 1 to unlock the box door 601, but also drive the L-shaped plate 202 to descend. The L-shaped plate 202 will slide downward in the transmission air box 107.

[0045] As Figure 7 and Figure 8 shown, two self-locking mechanisms are provided on the welding box 1. The self-locking mechanism includes a U-shaped mounting frame 801 fixedly installed on the right side of the welding box 1. A rectangular rod 802 is fixedly installed on the U-shaped mounting frame 801. A rectangular box 803 is slidably sleeved on the rectangular rod 802. A self-locking spring 804 is fixedly installed on the bottom inner wall of the U-shaped mounting frame 801. The top end of the self-locking spring 804 is fixedly connected to the rectangular box 803. An adaptation spring 806 is fixedly installed on the right inner wall of the rectangular box 803. The left end of the adaptation spring 806 is fixedly installed with a trapezoidal locking block 805. The left end of the trapezoidal locking block 805 penetrates through the rectangular limiting plate 602 and is slidably connected to the rectangular limiting plate 602.

[0046] During the rising process of the special-shaped plate 703, the rectangular rod 802 will drive the rectangular box 803 to rise under the action of the self-locking spring 804. When the trapezoidal locking block 805 contacts the notch on the welding box 1, the adaptation spring 806 that has been in a compressed state will push the trapezoidal locking block 805 into the welding box 1 and penetrate through the rectangular limiting plate 602 in the rectangular box 803.

[0047] During use, place the vascular forceps into the welding box 1, then close the box door 601, and start the vacuum pump 101. The vacuum pump 101 starts to suck air and draws air into the welding box 1 through the suction pipe 102. Since the cross-shaped chute 104 is not in a closed state at this time, the outside air will enter the welding box 1 under the action of the vacuum pump 101. During this process, when the air enters the welding box 1 from the cross-shaped chute 104, it will pass through several heating pipes 503. In the case of heating, the hot air will dry the vascular forceps and other facilities in the welding box 1, so that the moisture in the welding box 1 is sucked out of the welding box 1 under the action of the vacuum pump 101. At the same time, the vacuum pump 101 will also suck out the dust and impurities in the welding box 1. The sucked air will be discharged into the transmission air box 107 through the discharge pipe 103. The air will drive the round block 108 to move away from the vacuum pump 101. The round block 108 will drive the transmission rod 109 to move, and the transmission rod 109 will drive the closing plate 106 to move. At this time, several closing springs 105 will undergo compressive deformation. After the dust and impurities in the welding box 1 are sucked out, the closing plate 106 will close the cross-shaped chute 104 at this time, making the welding box 1 form a completely closed state. Since the air in the welding box 1 has not been exhausted at this time and the vacuum pump 101 continues to operate, during the continuous advancement of the round block 108, it will pass through the exhaust groove 201. At this time, the closing spring 105 will undergo further compression. As the gas in the transmission air box 107 accumulates more and more, the gas will be discharged from the gap between the round block 108 and the exhaust groove 201. When the welding box 1 is completely in a vacuum state, the vacuum pump 101 stops operating. Under the elastic force of the closing spring 105, the round block 108 will move a small distance in the direction closer to the vacuum pump 101 again. At this time, the round block 108 will cover the exhaust groove 201 to prevent air leakage, so that the closing plate 106 firmly closes the cross-shaped chute 104 and maintains the vacuum state in the welding box 1; when the transmission rod 109 moves in the direction away from the vacuum pump 101, the transmission rod 109 will drive the L-shaped flat plate 402 to move, and the L-shaped flat plate 402 will drive several trapezoidal blocks 403 to touch the L-shaped transmission plate 401. Under the action of the inclined surface of the trapezoidal block 403, the trapezoidal block 403 will pass through the L-shaped transmission plate 401, and the L-shaped transmission plate 401 will move upward. The L-shaped transmission plate 401 will drive the rectangular movable frame 304 to rise. At this time, the dust removal spring 305 will undergo elastic compression. After the trapezoidal block 403 leaves the L-shaped transmission plate 401, the L-shaped transmission plate 401 will descend under the action of the dust removal spring 305. During this process, the rectangular movable frame 304 will move up and down reciprocally. The rectangular movable frame 304 will drive several scraping plates 306 to clean the dust and impurities on the surface of the dust-proof filter plate 302, preventing the dust and impurities from clogging the filter holes on the dust-proof filter plate 302;

[0048] During the process of dust removal and air suction for the welding box 1, since the external gas enters the welding box 1 from the cross chute 104, and when the air enters the welding box 1 from the cross chute 104, it will blow towards the box door 601. Before closing the box door 601, the hydraulic cylinder 702 needs to be started. The hydraulic cylinder 702 drives the special-shaped plate 703 to descend. The special-shaped plate 703 drives the two rectangular boxes 803 to descend. The trapezoidal locking blocks 805 in the rectangular boxes 803 will slide out of the welding box 1 under the action of the inclined plane. At this time, the box door 601 and the rectangular limiting plate 602 are installed on the welding box 1. Then, the hydraulic cylinder 702 is started again to raise the special-shaped plate 703. During the rising process of the special-shaped plate 703, the rectangular rod 802 will drive the rectangular box 803 to rise under the action of the self-locking spring 804. When the trapezoidal locking block 805 touches the notch on the welding box 1, the adaptive spring 806 that has been in a compressed state will push the trapezoidal locking block 805 into the welding box 1 and penetrate the rectangular limiting plate 602 in the rectangular box 803. At this time, the fixation of the rectangular limiting plate 602 and the box door 601 is completed; after welding, the hydraulic cylinder 702 is started. The hydraulic cylinder 702 drives the special-shaped plate 703 to descend. When the special-shaped plate 703 descends, it will not only push the trapezoidal locking block 805 out of the welding box 1 to unlock the box door 601, but also drive the L-shaped plate 202 to descend. The L-shaped plate 202 will slide down in the transmission air box 107. At this time, half of the rectangular groove 203 on the L-shaped plate 202 will be exposed outside the transmission air box 107 and half will be inside the transmission air box 107. At this time, the air in the transmission air box 107 and the air outlet pipe 103 will be discharged from the rectangular groove 203. Since there is no gas support for the round block 108, the closing plate 106 will descend under the elastic force of several closing springs 105 to open the cross chute 104. At this time, the box door 601 is opened.
