Description

Technical Field

[0001] This invention relates to the field of electrocardiogram (ECG) chest electrode equipment technology, and more particularly to an ECG chest electrode assembly device and method. Background Technology

[0002] Electrocardiographs (ECGs), indispensable medical electronic instruments in clinical diagnosis and research, primarily function to accurately capture and record the weak bioelectrical signals generated by myocardial excitation during cardiac activity—the electrocardiogram (ECG). The pre-beating excitation process of the heart is accompanied by the conduction of electrical current. This current travels through different tissues and at varying distances to different parts of the body, resulting in varying potential changes on the body surface. This correlation between the internal electrical activity of the heart and the changes in external surface potential over time is collectively known as an electrocardiogram.

[0003] An electrocardiogram (ECG) monitor is a portable medical device that enables real-time and continuous monitoring of an individual's heart. Its detection mechanism is similar to that of an electrocardiograph (ECG) machine, but its portability, ease of use, instant feedback, and ability to adaptively adjust the ECG display amplitude provide strong support for early screening of heart disease and cardiovascular health management in sub-healthy individuals. It also provides doctors with important physiological information about patients.

[0004] Chest electrodes play a crucial role in the application of electrocardiographs and cardiac monitors. However, current manufacturing processes for chest electrodes face numerous challenges. Specifically, the significant interference fit between the balloon mounting hole and the electrode holder not only increases the difficulty of alignment during installation but also makes manual installation a labor-intensive and inefficient task. Prolonged manual operation can also cause occupational injuries to the operator's finger joints. Furthermore, manual assembly can lead to misalignment, affecting the overall performance of the product.

[0005] In view of the above problems, a method for assembling electrocardiogram (ECG) chest electrodes has been developed to improve and optimize the existing production process. This method has high practical value and is expected to solve the problems of high labor intensity, low efficiency and unstable assembly quality caused by manual installation, bringing about a revolutionary change in the production of ECG chest electrodes.

[0049] To make the above-mentioned objects, features, and advantages of the present invention more readily understood, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Many specific details are set forth in the following description in order to provide a thorough understanding of the present invention; however, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0050] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "fixation," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0051] Figures 1 to 16 The electrocardiogram chest electrode assembly device shown includes a transport mechanism 100, a pushing mechanism 200, a pressing mechanism 300, and an anti-dislodgement mechanism 400. The transport mechanism can continuously transport parts to the designated work station. In addition, the pushing mechanism can not only push the parts to the designated position, but also adapt to parts of different sizes and complete the center positioning, which facilitates the subsequent pressing mechanism to work on them. Furthermore, the pressing mechanism can prevent the suction force on the parts from still existing when the suction plate stops working.

[0052] The transport mechanism 100 includes a first motor 101 and a first roller 102 disposed on both sides of the first motor 101. The first roller 102 is disposed on one end of the annular conveyor belt 103, and a second roller 104 is disposed on the other end of the conveyor belt 103. A limit plate 105 is disposed on the outer side of the conveyor belt 103.

[0053] The pushing mechanism 200 includes a first cylinder 201 located in front of the first motor 101, a support block 202 located at the front end of the first cylinder 201, and a second motor 203 located inside the support block 202.

[0054] The pressing mechanism 300 includes a base plate 301 disposed at the bottom of the first cylinder 201, a support frame 302 disposed on one side of the base plate 301, a second cylinder 303 disposed inside the support frame 302, and a connecting block 304 connected to one side of the second cylinder 303.

[0055] The anti-detachment mechanism 400 includes a chest suction bulb 401, with a metal electrode 402 connected to the bottom of the chest suction bulb 401, and a first elongated block 403 disposed on one side of the metal electrode 402.

[0056] In use, the staff places the parts on the two conveyor belts 103 respectively, and starts the first motor 101 to drive the first roller 102 to rotate, which in turn causes the two conveyor belts 103 and the second roller 104 to rotate, thereby transporting the parts to the designated work area.

[0057] The second motor 203 drives the drive shaft 203a. A drive gear 204 is fixedly installed on the top of the drive shaft 203a. The drive gear 204 is connected to a limiting component 205. The limiting component 205 includes a first driven gear 205a. The first driven gear 205a is meshed with the drive gear 204. Three first arc-shaped grooves 205a-1 are symmetrically opened outward from the center of the first driven gear 205a. The first driven gear 205a is rotatably connected to a first support shaft 205b. The first support shaft 205b is fixedly connected to the center of the first limiting disk 205d. A first limiting groove 205d-1 corresponding to the first arc-shaped grooves 205a-1 is opened through the surface of the first limiting disk 205d. A moving block 205c is provided inside the first limiting groove 205d-1. The first driven gear 205a is connected to a toothed belt 205e.

[0058] The second motor 203 drives the drive shaft 203a to rotate, which in turn drives the drive gear 204 to rotate, and then the first driven gear 205a starts to rotate. Because the first driven gear 205a has a first arc-shaped groove 205a-1 and the first limiting disk 205d has a first limiting groove 205d-1 through it, when it rotates, it can drive the moving block 205c to move. Thus, the moving block 205c can move closer to or further away from the central area according to the driving method of the second motor 203. Because the top of the moving block 205c is provided with a special arc-shaped surface, it can fit with the inner surface of the electrode.

[0059] The other end of the toothed belt 205e is connected to a positioning component 206. The positioning component 206 includes a second driven gear 206a. The second driven gear 206a has three second arc-shaped grooves 206a-1 symmetrically extending outward from the center of its disk surface. The second driven gear 206a is rotatably connected to a second support shaft 206b. The second support shaft 206b is fixedly connected to a second limiting disk 206d. The second limiting disk 206d has a second limiting groove 206d-1 corresponding to the second arc-shaped grooves 206a-1. A positioning block 206c is provided inside the second limiting groove 206d-1.

[0060] Driven by the toothed belt 205e, the second driven gear 206a begins to rotate. Due to the second arc-shaped groove 206a-1 opened in the second driven gear 206a, and the second limiting disk 206d passing through the second limiting groove 206d-1, the second driving gear 206a can drive the positioning block 206c to move when it rotates. Thus, the positioning block 206c can move closer to or further away from the central area according to the driving mode of the second motor 203. Since the top of the positioning block 206c is provided with a special arc-shaped surface, it can fit with the inner surface of the chest suction bulb, thereby achieving a good positioning effect. Moreover, the second arc-shaped groove 206a-1 is different in size from the first limiting groove 205d-1, thus ensuring stable operation.

[0061] A second cylinder 303 is provided at one end of the inner side of the support frame 302. The second cylinder 303 is connected to a connecting block 304. A third cylinder 305 is fixedly connected to the connecting block 304. The telescopic rod of the third cylinder 305 is connected to a suction pump 306. The bottom of the suction pump 306 is connected to a suction cup 308 through a connecting pipe 307. The suction cup 308 is provided at the bottom of the connecting pipe 307. A working plate 309 is provided at the position where the suction cup 308 extends downward to the bottom plate 301.

[0062] The connecting pipe 307 includes a pipe body and a support ring 307a. Multiple limiting grooves 307b are symmetrically arranged on the inner wall of the pipe body. A through hole 307c is provided at the end of the limiting groove 307b away from the support ring 307a. A round rod 307d is slidably connected in the through hole 307c. A first spring 307e is sleeved on the surface of the round rod 307d. One end of the first spring 307e is connected to a protrusion extending outward from the support ring 307a. The width and thickness of the protrusion match the width and thickness of the limiting groove. Several fixing rods 307f are symmetrically arranged on the surface of the support ring 307a facing the pipe body. A second spring 307g is inclinedly arranged at the free end of the fixing rod 307f. A folding plate 307h is connected at the other end of the second spring 307g. A rotating pipe 307i is fixedly arranged at one end of the folding plate 307h.

[0063] A rotating tube 307i is fixedly installed at the root of the folding plate 307h. The rotating tube 307i is rotatably connected to the limiting ring 307j. The limiting ring 307j is fixedly installed inside the support ring 307a by several long blocks. An annular groove 307k is opened inside the support ring 307a. A force-bearing rod 307l is installed at the bottom of the round rod 307d. A third spring 307m is installed on the outer surface of the force-bearing rod 307l. A squeezing plate 307n is installed at one end of the force-bearing rod 307l. A sealing block 307n-1 is installed on one side of the squeezing plate 307n. An air outlet 307n-1a is opened through it. The squeezing plate 307n is installed inside the air storage chamber 307o. An air outlet 307p is installed on one side of the air storage chamber 307o.

[0064] Furthermore, by activating the third cylinder 305, the suction pump 306 is moved closer to the chest suction bulb. Activating the suction pump 306 causes the support ring 307a to move first. During this process, because the force rod 307l is fixedly connected to the round rod 307d and the compression disc 307n, the compression disc 307n begins to move and compresses the third spring 307m, causing the air outlet 307p and the air discharge port 307p to begin to shift, allowing the air storage chamber 307o to retain a certain amount of air. As the gas is drawn in, the suction force continues to increase. The folding plate 307h begins to rotate around the limiting ring 307j, overcoming the tension of the second spring 307g. This allows it to begin drawing in the air from the pipe and the upper surfaces of the suction cup and the chest suction ball, completing the adsorption process. The chest suction ball 401 is then moved upward by the third cylinder 305. Next, the connecting block 304 is moved by the second cylinder 303. When it moves above the working plate 309, the third cylinder 305 again moves it downward, completing the pressing of the electrode on the positioning component 206. After installation, the suction pump 306 stops working, the folding plate 307h resets and moves back to its original position along with the support ring 307a, the compression plate 307n and the sealing block 307n-1 begin to reset, and compress the gas inside the air storage chamber 307o, so that it is discharged into the pipeline through the air outlet 307p. Under the compression of the folding plate 307h and the support ring 307a, the gas is transferred to the suction cup, so that the suction cup is completely separated from the chest suction bulb, preventing the suction cup from still having suction on the chest suction bulb.

[0065] In some embodiments, the anti-detachment mechanism 400 further includes a rotating component 404, which includes a rotating rod 404a. The rotating rod 404a is connected to a rotating block 404b and a first gear 404c. A pressing rod 404d is provided at the bottom of the first gear 404c. A moving component 404e is attached to the bottom of the pressing rod 404d. The moving component 404e includes an arc-shaped block 404e-1. A connecting block 404e-2 and a second long block 404e-3 are connected to one side of the arc-shaped block 404e-1. A limiting round rod 404e-4 and a fourth spring 404e-5 are provided at the bottom of the connecting block 404e-2. A connecting long rod 404e-6 is provided on one side of the connecting block 404e-2.

[0066] The first gear 404c is meshed with the first rotating gear 405, the first rotating gear 405 is connected to the second rotating gear 407, the second rotating gear 407 is connected to the second clamping block 408, and the first rotating gear 405 is connected to the first clamping block 406.

[0067] A check valve 409 is provided on one side of the rotating rod 404a. The check valve 409 includes a moving part 409a. An arc-shaped limit block 409b and a wrench 409c are respectively provided on both sides of the moving part 409a. A fifth spring 409d is provided on one side of the moving part 409a. The fifth spring 409d is located inside the fixed block 409e.

[0068] When the pressing operation is completed, the operator first holds the push wrench 409c so that the arc-shaped limit block 409b moves away from the rotating rod 404a. The moving part 409a begins to compress the fifth spring 409d and begins to rotate the rotating block 404b. As a result, the first gear 404c drives the pressing rod 404d to rotate. Since the bottom of the pressing rod 404d is arc-shaped and the height of the arc-shaped block 404e-1 gradually increases from one end to the other, the degree of pushing of the pressing rod 404d on it continuously increases. As a result, the moving part 404e drives the second long block 404e-3 to descend, which works with the first long block 403 to fix the wire. At the same time, the first gear 404c drives the first rotating gear 405 to start rotating. The first rotating gear 405 drives the second rotating gear 407 to rotate, so that the first clamping block 406 and the second clamping block 408 begin to reinforce the connection between the chest suction bulb and the electrode, effectively preventing it from falling off.

[0069] The assembly method of the present invention includes the following steps:

[0070] A. Place the chest suction bulb 401 and the metal electrode 402 in the two conveyor belts 103 of the transport mechanism 100 respectively, and transport the chest suction bulb 401 and the metal electrode 402 respectively through the conveyor belts;

[0071] B. When transported to the workstation, the chest suction bulb 401 and the metal electrode 402 are placed in the limiting component 205 and the positioning component 206 respectively;

[0072] C. Start the first cylinder 201 to push the support block 202 to the designated position;

[0073] D. Start the pressing mechanism 300, and push the suction cup to adsorb the chest suction ball 401 through the power cylinder, and then move it to the top of the working plate 309 and press it down to the metal electrode 402 on the working plate, thereby completing the assembly of the chest suction ball 401 and the metal electrode 402.

[0074] E. The anti-detachment mechanism 400 prevents the thoracic suction bulb 401 from detaching from the metal electrode 402.

[0075] The specific process is as follows: The staff places the parts on two conveyor belts 103 respectively. The first motor 101 is started to drive the two first rollers 102 to roll. The two conveyor belts 103 move the second rollers to roll, thereby transporting the parts to the designated working area. The second motor 203 drives the drive shaft 203a to rotate, thereby the drive shaft 203a drives the drive gear 204 to rotate, and then the first driven gear 205a starts to rotate. Because the first driven gear 205a has a first arc-shaped groove 205a-1, and the first limiting plate 205d has a first limiting groove 205d-1 through it, when it rotates, it can drive the moving block 205c to move. Thus, the moving block 205c can move closer to or away from the central area according to the driving mode of the second motor (203). Because the top of the moving block 205c is provided with a special arc-shaped surface, it can fit with the inner surface of the electrode.

[0076] Driven by the toothed belt 205e, the second driven gear 206a begins to rotate. Due to the second arc-shaped groove 206a-1 on the second driven gear 206a, and the second limiting disc 206d having a second limiting groove 206d-1 extending through it, the rotation of the gear drives the positioning block 206c to move. The positioning block 206c can then move closer to or further from the center area according to the driving mode of the second motor 203. Because the top of the positioning block 206c has a special arc-shaped surface, it can fit against the inner surface of the chest suction bulb, achieving a good positioning effect. Furthermore, the second arc-shaped groove 206a-1 is of a different size than the first limiting groove 205d-1, ensuring stable operation. First, the third cylinder 305 is activated, moving the suction pump 306 closer to the chest suction bulb and starting the suction pump. 306, causing the support ring 307a to move first. During this process, since the force rod 307l is fixedly connected to the round rod 307d and the extrusion plate 307n, the extrusion plate 307n begins to move and extrudes the third spring 307m, thereby causing the air outlet 307p and the air outlet 307p to start to be misaligned, so that the air storage chamber 307o contains a certain amount of gas, and the suction force continues to increase. The folding plate 307h begins to overcome the tension of the second spring 307g and rotates around the limiting ring 307j, thereby starting to suck up the air in the pipe and the upper surface of the suction cup and the chest suction ball, completing the adsorption. The chest suction ball is moved upward by the third cylinder 305, and then the connecting block 304 is moved by the second cylinder 303. When it moves above the working plate 309, the third cylinder 305 again drives it to descend, completing the pressing of the electrode on the positioning component 206. After installation, the suction pump 306 stops working, the folding plate 307h resets and moves back to its original position along with the support ring 307a, the compression plate 307n and the sealing block 307n-1 begin to reset, and compress the gas inside the air storage chamber 307o, so that it is discharged into the pipeline through the air outlet 307p. Under the compression of the folding plate 307h and the support ring 307a, the gas is transferred to the suction cup, so that the suction cup is completely separated from the chest suction bulb, preventing the suction cup from still having suction on the chest suction bulb.

[0077] When the pressing operation is completed, the operator first holds the push wrench 409c so that the arc-shaped limit block 409b moves away from the rotating rod 404a. The moving part 409a begins to compress the fifth spring 409d and begins to rotate the rotating block 404b. As a result, the first gear 404c drives the pressing rod 404d to rotate. Since the bottom of the pressing rod 404d is arc-shaped and the height of the arc-shaped block 404e-1 gradually increases from one end to the other, the pressing rod 404d continuously increases its pushing force. As a result, the moving part 404e drives the second long block 404e-3 to descend, which works with the first long block 403 to fix the wire. At the same time, the first gear 404c drives the first rotating gear 405 to start rotating. The first rotating gear 405 drives the second rotating gear 407 to rotate, thereby the first clamping block 406 and the second clamping block 408 begin to reinforce the connection between the chest suction bulb and the electrode, effectively preventing it from falling off.

[0078] The transport mechanism can continuously transport parts to designated workstations. In addition, the pushing mechanism can not only push parts to designated positions, but also adapt to parts of different sizes and complete center positioning, which facilitates the subsequent pressing mechanism to work on them. The pressing mechanism can prevent the suction plate from still having suction on the parts when it stops working. The anti-detachment mechanism can easily prevent parts from falling off and also prevent wiring from coming loose.

[0079] This invention can be modified and varied in various ways. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the scope of protection of this invention.
