Description

Technical Field

[0001] The utility model belongs to the technical field of welding machines, and in particular relates to an ultrasonic welding machine. Background Art

[0002] An ultrasonic welder is a device that uses ultrasonic vibrations to generate heat for metal assembly or thermoplastic welding. During operation, an ultrasonic generator generates a high-frequency ultrasonic oscillation signal, which is then transmitted to a transducer, which converts the electrical energy into mechanical vibrations. The mechanical vibrations are transmitted to the welding area through the welding head, causing friction and displacement between molecules on the workpiece surface, thereby generating localized heat. This localized heat softens or melts the workpiece surface, tightly bonding the two objects together to form a welded joint. After welding is completed, the material cools and solidifies, forming a strong weld. Compared to traditional resistance welding and laser welding, ultrasonic welding offers advantages such as low energy consumption, high welding speed, the absence of additional filler materials, and zero pollution.

[0003] Although ultrasonic welding machines are pollution-free, in actual use, especially when welding plastic workpieces, the plastic workpieces are melted by heat and tend to emit a certain odor. Existing ultrasonic welding machines lack gas purification mechanisms, which makes it easy for workers to inhale odorous gases. Over time, it is easy to cause harm to the workers' health.

[0004] Therefore, in view of the above technical problems, it is necessary to provide an ultrasonic welding machine.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0031] like Figures 1 to 4 As shown, an ultrasonic welding machine in one embodiment of the present invention includes a base 1 and a purification mechanism 2.

[0032] A welding platform 101 is installed on the base 1 , and the welding platform 101 is used to install the mold. Through the mutual cooperation between the mold and the welding mechanism 103 , the welding of the plastic workpiece can be achieved.

[0033] In addition, an adjusting rod 102 is fixedly connected to the welding table 101 . The adjusting rod 102 is used to install the welding mechanism 103 and can adjust the height of the welding mechanism 103 .

[0034] Specifically, a welding mechanism 103 is installed on the adjusting rod 102, and the welding mechanism 103 is used to perform ultra-high

[0035] Sonic welding.

[0036] Preferably, the base 1, welding table 101, adjusting rod 102 and welding mechanism 103 used in this application are all existing technologies, and the connections between the various components of the base 1, welding table 101, adjusting rod 102 and welding mechanism 103 are also existing technologies. Therefore, their connections and working principles will not be elaborated here.

[0037] like Figures 1 to 4As shown, the purification mechanism 2 is installed on the base 1. The purification mechanism 2 is used to absorb and treat the odorous gas generated during the welding of plastic workpieces, so that the odorous gas is not easy to overflow, thereby reducing the probability of workers inhaling the odorous gas, and also creating a good working environment for the workers.

[0038] The purification mechanism 2 includes a purification box 201, which is mounted on the side wall of the base 1. The purification box 201 is provided with an installation cavity 202, a negative pressure cavity 203, and a purification cavity 204. An air pump 205 is installed in the installation cavity 202. The air suction end of the air pump 205 is located in the negative pressure cavity 203, and the air discharge end of the air pump 205 is located in the purification cavity 204. When the air pump 205 is running, the air pump 205 can absorb the gas in the negative pressure cavity 203, thereby forming a negative pressure inside the negative pressure cavity 203. The gas absorbed by the air pump 205 is transported to the purification cavity 204.

[0039] In addition, a purification liquid 206 is provided in the purification chamber 204 , and the purification liquid 206 is used to purify the gas delivered by the vacuum pump 205 .

[0040] Preferably, the purification liquid 206 is a commercially available product and can be purchased and used directly.

[0041] Specifically, a negative pressure pipe 207 is connected to the purification box 201, one end of which is located in the negative pressure chamber 203. When a negative pressure is formed inside the negative pressure chamber 203, the negative pressure chamber 203 will also form a negative pressure inside the gas collection hood 208 through the negative pressure pipe 207, thereby absorbing the odorous gas generated during the welding of plastic workpieces.

[0042] In addition, a liquid replacement pipe is provided on the side wall of the purification box 201 , and the liquid replacement pipe is connected to the purification chamber 204 for replacing the purification liquid 206 .

[0043] like Figures 1 to 4 As shown, the end of the negative pressure tube 207 away from the purification box 201 is connected to an air suction mechanism, which is used to absorb the odorous gas generated during the welding of the plastic workpiece, so that the odorous gas is not easy to overflow, thereby reducing the probability of the staff inhaling the odorous gas, and also creating a good working environment for the staff.

[0044] The air suction mechanism includes an air collecting hood 208, which is connected to the negative pressure pipe 207. When negative pressure is formed inside the negative pressure chamber 203, the negative pressure chamber 203 can also form a negative pressure inside the air collecting hood 208 through the negative pressure pipe 207, thereby absorbing the odorous gas generated when welding the plastic workpiece on the welding table 101, making it difficult for the odorous gas to escape, thereby reducing the probability of workers inhaling the odorous gas and creating a good working environment for them.

[0045] In addition, a mounting plate 209 is mounted on the welding table 101, and the mounting plate 209 is mounted on the welding table 101 by bolts, which facilitates the removal of the gas collecting hood 208. A bracket 210 is fixedly connected to the mounting plate 209, and the bracket 210 is used to mount the gas collecting hood 208. A screw 211 is threadedly connected to the bracket 210.

[0046] Specifically, bracket 210 is provided with an adjustment slot, in which a connecting block 212 is slidably mounted. Connecting block 212 is threadedly connected to screw rod 211 and fixedly connected to gas hood 208. When screw rod 211 rotates, connecting block 212 is acted upon by the thread to move up and down, thereby adjusting the position of gas hood 208, allowing gas hood 208 to better absorb odorous gases generated during the welding of plastic workpieces.

[0047] like Figures 1 to 4 As shown, one end of the negative pressure tube 207 located in the negative pressure chamber 203 is connected to an air diffuser 213, and a filter 214 is provided on the lower side of the air diffuser 213. The filter 214 is used to filter the odorous gas so that impurities in the odorous gas are not easily affected by the air pump 205.

[0048] The side wall of the purification box 201 is hinged with a cover door, which corresponds to the filter screen 214 to facilitate cleaning of the filter screen 214.

[0049] In addition, the outlet end of the air pump 205 located in the purified liquid 206 is connected to a straight pipe 215.

[0050] A plurality of evenly distributed nozzles are connected to the pipe 215. The odorous gas sucked by the air pump 205 is transported into the purification chamber 204 and discharged to the purification liquid 206 through the plurality of nozzles on the straight pipe 215 so as to purify the odorous gas.

[0051] like Figures 1 to 4 As shown, a flow chamber is provided in the purification box 201, a baffle 216 is installed in the flow chamber, and a drying cotton 217 is provided between the baffle 216 and the side wall of the flow chamber. The drying cotton 217 is used to dry the purified gas.

[0052] The sidewall of the purification chamber 204 is provided with a first through-hole 218, which connects the purification chamber 204 to the flow chamber. The baffle 216 is provided with a second through-hole 219. The purified gas enters the flow chamber through the first through-hole 218, is dried by the drying cotton 217, and then continues to flow through the second through-hole 219.

[0053] In addition, the liquid level of the purification liquid 206 is lower than the height of the first through hole 218 , and the second through hole 219 is provided on the lower side of the drying cotton 217 , so that the purified gas can be dried by the drying cotton 217 .

[0054] Specifically, a plurality of third through holes 220 are provided on the bottom wall of the installation cavity 202, and the installation cavity 202 is connected with the flow cavity through the third through holes 220. The dried gas will enter the installation cavity 202, which is used to accelerate the flow rate of the gas in the installation cavity 202, so that heat is not easily accumulated, and thus the vacuum pump 205 is not prone to high temperature during long-term operation.

[0055] In addition, an air outlet is provided on the side wall of the purification box 201 , and the installation cavity 202 is connected to the outside through the air outlet, and the gas in the installation cavity 202 is discharged through the air outlet.

[0056] In specific use, when welding a plastic workpiece, the vacuum pump 205 is operated to absorb the gas in the negative pressure chamber 203, thereby forming a negative pressure inside the negative pressure chamber 203. The negative pressure chamber 203 will also form a negative pressure inside the gas collecting hood 208 through the negative pressure pipe 207, thereby absorbing the odorous gas generated during the welding of the plastic workpiece, making it difficult for the odorous gas to overflow, thereby reducing the risk of workers.

[0057] It reduces the probability of inhaling odorous gases and also creates a good working environment for the staff.

[0058] Odor-inducing gases first enter negative pressure chamber 203 and are filtered by filter 214, removing impurities from the gases and preventing them from affecting vacuum pump 205. Gas drawn by vacuum pump 205 is transported to purification chamber 204 and discharged through nozzles on straight pipe 215 toward purification liquid 206, which then purifies the odor-inducing gases.

[0059] The purified gas enters the flow chamber through the first through-hole 218, is dried by the drying cotton 217, and then continues to flow through the second through-hole 219. The gas in the flow chamber enters the installation chamber 202 through the third through-hole 220, which accelerates the flow rate of the gas in the installation chamber 202, preventing heat accumulation and thus cooling the air pump 205. The gas in the installation chamber 202 is finally discharged through the air outlet.

[0060] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
