High efficiency razor handle welding machine

Abstract

The present application relates to the field of razor production, and particularly relates to a high-efficiency razor backbone welding machine. The machine comprises a rotating disc type workbench and a conveying belt. The conveying belt is fixed on the rotating disc type workbench. By inserting the sealing block into the installation groove, a first cavity is formed among the first fixed block, the electromagnetic block, the razor blade and the sealing block. Then, air is blown into the first cavity through the air blowing groove. If the installation groove has defects, the air entering the first cavity will enter the backflow groove and be discharged from the exhaust pipe. When the airflow detection sensor in the exhaust pipe detects the airflow signal, it is determined that the installation groove is unqualified. Otherwise, it is determined that the installation groove is qualified. Thus, the installation groove of the razor blade is detected to avoid defects in the installation groove, which may cause the razor blade to fail to fit with the installation column on the backbone, and further cause the razor blade to shake or deviate on the backbone, thereby affecting the subsequent assembly and welding quality.

[0002] Razor keel welding is to clamp the razor blade between the upper and lower frames of the razor, and then fix the upper and lower frames and the blade by assembly and welding; in the existing technology, the razor keel is usually assembled and welded through a turntable workbench. The production process includes loading the lower frame, assembling the blade, loading the upper frame, assembling, welding and unloading.

[0003] There is usually an installation slot in the middle of the razor blade. During the assembly process, the installation slot needs to be aligned with the mounting post on the frame and inserted into the mounting post to limit the razor blade and prevent the razor blade from shaking in the frame, thereby affecting the subsequent assembly and welding quality. However, during the production process of the razor blade, defects may appear in the installation slot of the razor blade due to insufficient mold precision, unstable processing equipment parameters, improper manual operation, etc. The razor blade cannot fit with the mounting post on the frame, causing the razor blade to shake or shift on the frame, thereby affecting the subsequent assembly and welding quality. Therefore, the installation slot of the razor needs to be inspected to screen out unqualified blades. Summary of the Invention

[0006] Preferably, the loading assembly includes a blade loading robot, a connector and a suction pipe; a blade loading robot is installed on a turntable workbench; a connector is fixedly connected to the blade loading robot; the connecting pipe is connected to the external air pump through the connector; the exhaust pipe is connected to the external air pump through the connector; a second connecting groove is provided in the connecting pipe; a third cavity is provided in the second fixed block; the second connecting groove is connected to the third cavity; a number of suction pipes are fixedly connected to the lower side of the second fixed block; each suction pipe is connected to the third cavity.

[0007] Preferably, the upper surface of the electromagnetic block is configured to be a smooth surface.

[0008] Preferably, the suction pipes are distributed in a rectangular array.

[0009] Preferably, the first fixing block is detachably connected to the conveyor belt via a snap-fit ​​structure.

[0010] Preferably, the blowing groove is flared.

[0011] Preferably, it further comprises an electric push rod and a telescopic tube; the electric push rod is fixedly connected to the second fixed block; the output end of the electric push rod is fixedly connected to the sealing block; and the telescopic tube is connected between the sealing block and the connecting tube.

[0012] Preferably, an elastic pad is further included; and an elastic pad is fixedly connected to the lower side of each second fixing block.

[0013] As a preference, a visual detector is also included; a plurality of visual detectors are fixedly connected to the left side of the conveyor belt.

[0014] Preferably, the air inlet of each suction pipe is provided with a filter.

[0015] Compared with the prior art, the present invention has the following advantages: by inserting the sealing block into the mounting groove, a first cavity is formed between the first fixing block, the electromagnetic block, the razor blade and the sealing block, and then air is blown into the first cavity through the blowing groove. At this time, if there is a defect in the mounting groove, the gas will enter the first cavity and then enter the reflux groove and be discharged from the exhaust pipe. When the air flow detection sensor in the exhaust pipe detects the gas flow signal, the mounting groove is judged to be unqualified; otherwise, the mounting groove is judged to be qualified, thereby testing the mounting groove of the razor blade, avoiding defects in the mounting groove, which may cause the razor blade to fail to fit with the mounting post on the frame, and then cause the razor blade to wobble or deflect on the frame, thereby affecting the subsequent assembly and welding quality;

[0016] Before the suction tube sucks the razor blade, dust and impurities on the upper surface of the razor blade are blown away through the flared blowing groove. When the razor blade is separated from the electromagnetic block, air is continued to be blown into the first cavity through the blowing groove, thereby increasing the air pressure in the first cavity, thereby squeezing the razor blade upward, making it easier to separate the razor blade from the electromagnetic block. At the moment the razor blade is separated from the electromagnetic block, the high-pressure airflow in the first cavity is blown outward from the gap between the electromagnetic block and the razor blade, thereby blowing away dust and impurities on the lower surface of the razor blade, thereby cleaning the razor blade and improving production quality.

[0017] The upper surface of the electromagnetic block is set to a smooth surface to prevent the electromagnetic block from scratching the lower surface of the razor blade, causing scratches on the razor blade and affecting the quality of the razor blade; and the electromagnetic block protrudes upward from the first fixed block, so that after the razor blade is placed on the electromagnetic block, the razor blade is in an overhead state, preventing the cutting edge of the razor blade from contacting the first fixed block, causing damage to the cutting edge of the razor blade and affecting the production quality of the razor.

[0018] The present invention also has the following beneficial effects: an elastic pad is fixed to the lower side of each second fixing block. When the second fixing block adsorbs the blade, the elastic pad reduces the contact wear of the second fixing block on the blade, thereby preventing damage to the blade.

[0028] The loading assembly includes a blade loading robot 3, a connector 4 and a suction pipe 106; a blade loading robot 3 is installed on the turntable workbench 1; a connector 4 is fixed to the blade loading robot 3; the connecting pipe 104 is connected to the external air pump through the connector 4; the exhaust pipe 105 is connected to the external air pump through the connector 4; a second connecting groove 10402 is provided in the connecting pipe 104; a third cavity 10303 is provided in the second fixed block 103; the second connecting groove 10402 is connected to the third cavity 10303; a number of suction pipes 106 are fixed to the lower side of the second fixed block 103; each suction pipe 106 is connected to the third cavity 10303.

[0029] The upper surface of the electromagnetic block 102 is set to a smooth surface to prevent the electromagnetic block 102 from scratching the lower bottom surface of the razor blade 5 and causing scratches on the razor blade 5.

[0030] The suction tubes 106 are distributed in a rectangular array, so that when suction is applied to the razor blades 5, the suction force applied to the surface of the razor blades 5 is more uniform, thereby preventing the razor blades 5 from being deformed or damaged due to uneven force applied during suction.

[0031] The first fixing block 101 is detachably connected to the conveyor belt 2 via a snap-fit ​​structure, which facilitates quick replacement and maintenance of the first fixing block 101 .

[0032] The air blowing groove 10701 is flared.

[0034] An elastic pad 108 is also included; an elastic pad 108 is fixed to the lower side of each second fixing block 103 .

[0035] The working principle of the above embodiment is as follows:

[0036] The injection-molded lower frame and upper frame are respectively transported to the lower frame loading station and the upper frame loading station by an external conveying device, and the razor blade 5 is transported to the adsorption loading position of the blade loading robot 3 by the conveyor belt 2. When the conveyor belt 2 transports the razor blade 5, the razor blade 5 is placed on the corresponding first fixed block 101, and the razor blade 5 is magnetically fixed by the electromagnetic block 102 to prevent the razor blade 5 from being displaced during the transportation process, thereby affecting the subsequent loading operation; during the assembly and welding process, the lower frame loading station will first place the lower frame in the clamping fixture of the turntable workbench 1, and then the turntable workbench 1 will drive the clamping fixture to rotate. When the clamping fixture moves to the adsorption loading position of the blade loading robot 3, the second The fixed block 103 is driven to the top of the corresponding razor blade 5, and then the second fixed block 103 is driven to move downward, so that the suction tube 106 contacts the upper surface of the razor blade 5, and then the external air pump is started to suck the razor blade 5 through the suction tube 106, and then the blade loading robot 3 is used to place the adsorbed razor blade 5 on the lower frame in the clamping fixture, and then the clamping fixture is moved to the upper frame loading station, and the upper frame loading station places the upper frame in the clamping fixture, and then when the clamping fixture is moved to the assembly station, the upper frame blade and the lower frame are assembled, and then the clamping fixture is moved to the welding station for welding and fixing, so that the assembly and welding operations of the razor keel can be fully automated, reducing manual participation, solving manpower waste, and greatly improving the production efficiency of razor keel assembly and welding.

[0037] A mounting groove 5001 is usually provided in the middle of the razor blade 5. During the assembly process, the mounting groove 5001 needs to be aligned with the mounting post on the frame and inserted into the mounting post to limit the razor blade 5 and prevent the razor blade 5 from shaking in the frame, thereby affecting the subsequent assembly and welding quality. However, during the production process of the razor blade 5, defects may appear in the mounting groove 5001 of the razor blade 5 due to insufficient mold accuracy, unstable processing equipment parameters, improper manual operation, etc. At this time, the razor blade 5 cannot fit with the mounting post on the frame, causing the razor blade 5 to shake or deviate on the frame, thereby affecting the subsequent assembly and welding quality. Therefore, it is necessary to inspect the mounting groove 5001 of the razor blade 5 and screen out unqualified blades; therefore, when the razor blade 5 is sucked through the suction tube 106, as shown in FIG. Figure 2-Figure 5 As shown: after the blade feeding robot 3 drives the second fixed block 103 to move downward, the lower surface of the second fixed block 103 will contact the razor blade 5, and then the sealing block 107 protruding downward from the second fixed block 103 will be inserted into the installation groove 5001, thereby blocking the installation groove 5001. At this time, a first cavity 10201 is formed between the first fixed block 101, the electromagnetic block 102, the razor blade 5 and the sealing block 107; at this time, when the installation groove 5001 of the razor blade 5 is When a defect occurs, after the sealing block 107 is inserted into the mounting groove 5001, there will inevitably be a gap between the mounting groove 5001 and the sealing block 107. Therefore, the first cavity 10201 is not sealed. By starting the external air pump to blow air into the blowing groove 10701, the gas enters the first cavity 10201 and then enters the reflux groove 10301 through the gap between the mounting groove 5001 and the sealing block 107, and then enters the second cavity 10302 and is discharged from the exhaust pipe 105. At this time, the air flow detection sensor 201 in the exhaust pipe 105 will detect the air flow information, and it can be judged that the installation slot 5001 is unqualified. Then, the unqualified razor blade 5 is sucked through the suction pipe 106, and the unqualified razor blade 5 is taken to the external waste recycling box through the blade loading robot 3 for recycling. When the installation slot 5001 of the razor blade 5 is qualified, the first cavity 10201 is in a sealed state after the sealing block 107 is inserted into the installation slot 5001. Therefore, when the external air pump is started to blow air into the blowing slot 10701, the gas cannot enter the reflux slot 10301, so the air flow detection sensor 201 will not detect the air flow information. At this time, the installation slot 5001 can be judged as a qualified product, and then the qualified razor blade 5 is sucked through the suction pipe 106, and the qualified razor blade 5 is placed on the lower frame in the clamping fixture through the blade loading robot 3 for subsequent assembly and welding operations.

[0038] Furthermore, it is also taken into consideration that the razor blades 5 are easily contaminated with dust and impurities in the air during the production and transportation process. Therefore, when the blade feeding robot 3 brings the second fixed block 103 to the top of the corresponding razor blade 5, air can be blown into the blowing groove 10701 through an external air pump, and then the air flow is blown out through the flared blowing groove 10701 to blow away the dust and impurities on the upper surface of the razor blade 5. When the blade feeding robot 3 drives the second fixed block 103 to move upward and separates the adsorbed qualified razor blade 5 from the electromagnetic block 102, it continues to pass through the blowing groove 10701. Air is blown into the first cavity 10201 to increase the air pressure in the first cavity 10201, thereby squeezing the razor blade 5 upward, making it easier for the blade loading robot 3 to drive the second fixed block 103 to move upward, and separating the adsorbed qualified razor blade 5 from the electromagnetic block 102. At the moment when the razor blade 5 is separated from the electromagnetic block 102, the high-pressure airflow in the first cavity 10201 will be blown outward from the gap between the electromagnetic block 102 and the razor blade 5, thereby blowing away the dust and impurities on the lower surface of the razor blade 5. By this method, the razor blade 5 is cleaned and the production quality is improved.

[0039] Furthermore, it is also considered that when assembling and welding some razor blades 5 that do not have installation grooves 5001, the electric push rod 202 can be used to drive the sealing block 107 to move upward so that the lower surface of the sealing block 107 is flush with the lower surface of the second fixed block 103, thereby avoiding the downwardly protruding sealing block 107 affecting the contact between the suction tube 106 and the surface of the razor blade 5, thereby affecting the adsorption effect. When the blade loading robot 3 brings the razor blade 5 to the top of the lower frame in the clamping fixture, the electric push rod 202 is used to drive the sealing block 107 to move upward and bring the sealing block 107 to the second fixed block 103. Therefore, when the blade loading robot 3 places the razor blade 5 on the lower frame, the second fixed block 103 can be directly inserted into the mounting column on the lower frame, and then the razor blade 5 can be directly inserted into the mounting column on the lower frame, ensuring that the razor blade 5 can be accurately installed on the lower frame.

[0040] Furthermore, the upper surface of the electromagnetic block 102 is set to a smooth surface to prevent the electromagnetic block 102 from scratching the lower surface of the razor blade 5, causing scratches on the razor blade 5 and affecting the quality of the razor blade 5; and the electromagnetic block 102 protrudes upward from the first fixed block 101, so that after the razor blade 5 is placed on the electromagnetic block 102, the razor blade 5 is in an overhead state, preventing the cutting edge of the razor blade 5 from contacting the first fixed block 101, causing damage to the cutting edge of the razor blade 5 and affecting the production quality of the razor.

[0041] On the basis of the above technical effects, the present invention also has the following advantages:

[0042] like Figure 4As shown, the suction tubes 106 are distributed in a rectangular array, so that when the razor blade 5 is sucked, the suction force on the surface of the razor blade 5 is more uniform, preventing the razor blade 5 from being deformed or damaged due to uneven force during suction.

[0043] like Figure 4 As shown, an elastic pad 108 is fixed to the lower side of each second fixing block 103. When the second fixing block 103 contacts the razor blade 5, the elastic pad 108 reduces the contact wear of the second fixing block 103 on the razor blade 5, thereby preventing the razor blade 5 from being damaged.

[0044] Example 2: Based on Example 1, Figure 2 As shown, a visual detector 109 is also included; two visual detectors 109 are fixedly connected to the left side of the conveyor belt 2.

[0045] The air inlet of each suction pipe 106 is provided with a filter 10601 .

[0046] The working principle of the above embodiment is as follows:

[0047] There are two visual detectors 109 fixedly connected to the left side of the conveyor belt 2. When the conveyor belt 2 transports the blade to the loading position on the left, the position of the blade is detected by the visual detector 109. When the conveyor belt 2 fails and causes the blade position deviation, an alarm is issued to prompt the staff to deal with it in time, so that the staff can discover and solve the problem in time and improve production efficiency.

[0048] Furthermore, when the suction pipe 106 is suctioning, dust and impurities are filtered and intercepted by the filter 10601 to prevent dust and impurities from being sucked into the suction pipe 106, causing the flow channel between the suction pipe 106 and the external air pump to be blocked or damaged. After the loading is completed, the external air pump is controlled to blow air into the suction pipe 106, thereby removing impurities on the filter 10601 and cleaning the filter 10601.

[0049] The above is a detailed introduction to the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core idea of ​​the present application. At the same time, for those skilled in the art, based on the idea of ​​the present application, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
