Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic welding machines, and in particular to an ultrasonic welding frame with conveniently adjustable stroke. Background Art

[0002] The ultrasonic welding frame with easy-to-adjust stroke is an important part of the ultrasonic welding system. It is mainly used to support and adjust the height and stroke of the ultrasonic welding head to meet different welding requirements. This frame makes the adjustment of the welding head simpler, more accurate and more efficient through its unique design.

[0003] As disclosed in the publication number CN117245921A, the invention relates to the field of welding technology and discloses an ultrasonic welding frame with conveniently adjustable stroke, including a bottom plate, the top of the bottom plate is fixedly connected to a top plate through a plurality of slide bars, an electric push rod is fixedly installed on the top of the top plate, the telescopic end of the electric push rod extends through the top plate and is fixedly connected to a connecting plate, the bottom of the connecting plate is fixedly connected to a bracket through a vertical rod, the bracket sliding sleeve is arranged on the outside of the slide bar, and a ball head cover is fixedly installed in the middle of the bracket. The invention can realize automatic avoidance of the welding machine when the welding machine is hit by an impact object when not in use, so that the welding machine can be protected and prevented from being damaged by the impact object, and the welding machine itself is easy to adjust the stroke of the welding machine to meet the use requirements, and the welding machine itself can be automatically reset after the avoidance is completed, so that the positioning structure can be docked with the ball body later, which is convenient for subsequent use.

[0004] In the above-mentioned prior art, when not working, the fixing threaded parts are loosened, so that the welding machine body is in a loose state. When the welding machine body is hit, the welding machine body is driven by force to drive the rotating rod, motor, mounting seat and sphere connected thereto to swing, and the rotation of the motor drives the welding machine body to rotate, so that the welding machine body rotates and rolls along the surface of the impactor to avoid the impactor. However, the welding machine body itself is heavy and in a vertical state. If the impact force of the impactor is small, the swing amplitude of the welding machine body is small. Therefore, the swinging force cannot start the motor rotation, thereby failing to avoid the impactor, and when the welding machine body is swinging, it has been hit by the impactor, so the welding machine body will still be damaged. Summary of the invention

[0005] The purpose of the present invention is to solve the problem in the prior art that the welding machine body itself is heavy and in a vertical state. If the impact force of the impact object is small, the swing amplitude of the welding machine body is small, so the swing force cannot start the motor rotation, thereby unable to avoid the impact object, and when the welding machine body swings, it has been hit by the impact object, so the welding machine body will still be damaged.

After the protective plate is deflected by a collision, and the deflection of the bottom end can adjust the connecting slider to slide along the second slide groove. Since the second slide grooves fit each other and the tips of the protective bottom plate are under pressure with each other, the protective bottom plate rises as the position of the protective plate is deflected, and the connecting slider slides in the second slide groove while driving the side of the protective bottom plate away from each other to tilt up, and the second spring is pulled after tilting up, so the wear-resistant force of the sliding pull of the connecting slider and the pulling force of the second spring can offset the collision force again. Secondly, when not in work, the protective bottom plates are tightly attached to each other to form a closed space with the protective plate, which can prevent the entry of external dust and keep the main body of the ultrasonic welding machine clean.

[0011] As a preferred embodiment, the top end of the protective bottom plate is located on the side where the second sliding groove is close to each other and is fixedly connected with a second spring. The top end of the second spring is fixedly connected to the protective plate. The second spring always pulls the protective bottom plate and can reset the protective bottom plate after deflection.

[0012] As a preferred embodiment, the blowing assembly includes an air pump, which is arranged on a side of the workbench close to the movable groove, one side of the air pump is fixedly connected with an air pipe, an end of the air pipe away from the air pump is fixedly connected with a branch connecting pipe, the branch connecting pipe is fixedly connected to one side of the second electric slider, both ends of the branch connecting pipe are fixedly connected with fixed pipes, the fixed pipes are fixed on both sides of the top of the fixed plate, the bottom end of the fixed pipe is equidistantly arranged and fixedly connected with a blowing head, the blowing head passes through the fixed plate and is fixedly connected to the fixed plate, during operation, the air pump is started, the gas enters the air pipe, enters the branch connecting pipe along the air pipe, and then enters the fixed pipe in a branched manner, and finally blows air into the space formed by the protective plate through the blowing head, the gas is discharged downward, and at the same time blows to the working ultrasonic welding machine body, so as to avoid the dust carried during work from entering the protective plate to pollute the ultrasonic welding machine body, and to blow away the dust attached to the ultrasonic welding machine body.

[0013] As a preferred embodiment, the trachea is slidably connected to a limiting tube at the movable groove, and a movable connecting block is fixedly connected to the bottom end of the limiting tube. The movable connecting block is slidably connected to the movable groove and fixedly connected to the first electric slider. The movement of the first electric slider drives the movable connecting block to move, and the movement of the movable connecting block drives the limiting tube to move, thereby always pulling the trachea.

[0014] As a preferred embodiment, a reset member is provided at one end of the air pipe located at the limit tube close to the air pump, and the reset member includes a reset connecting block, and a lifting slider is fixedly connected to the side of the reset connecting block close to the support frame, and the lifting slider is slidably connected to the inside of the lifting slide groove, and the bottom end of the lifting slider is fixedly connected to a third spring, and the third spring is fixed to the inside of the workbench. When the second electric slider moves to the side away from the air pump, the air pipe can be pulled, and the air pipe is forced to move upward to pull the fixed cylinder. The movement of the fixed cylinder drives the reset connecting block to move, and the reset connecting block drives the lifting slider to slide along the trajectory of the lifting slide groove and pull the third spring.

[0015] As a preferred embodiment, a buffer groove is provided on one side of the middle part of the reset connecting block that is close to each other, and a buffer slider is slidably connected inside the buffer groove, and one end of the buffer sliding block that is close to each other is fixedly connected to a fixed shaft, and one end of the fixed shaft that is close to each other is fixedly connected to a fixed cylinder, and the fixed cylinder is fixedly connected to the air pipe, and a fourth spring is fixedly connected to the side of the buffer sliding block close to the lifting sliding block, and the fourth spring is fixedly connected to the reset connecting block. When the second electric sliding block slides toward one side of the air pump, the third spring loses tension and starts to rebound, and the third spring pulls the lifting sliding block down, and the lifting sliding block drives the reset connecting block to move downward, and the reset connecting block pulls the air pipe back through the fixed cylinder, thereby realizing the extension and retraction of the air pipe with the movement of the second electric sliding block, thereby increasing convenience.

[0016] The beneficial effects of the present invention are as follows: In the present invention, when an external object collides with the ultrasonic welding machine body, it will be blocked by the protective plate. When the protective plate is subjected to the force of the collision, it deflects with the support ring as the axis, and the deflection drives the first connecting head to move. The first connecting head drives the reverse thrust rod to squeeze the fixed rod, so that the reverse thrust rod deflects at the connection at the bottom end of the fixed rod. The deflection of the reverse thrust rod can drive the fixed ring to deflect. The deflection of the fixed ring pulls the first spring, and the first spring is stretched, thereby offsetting the force generated during the collision, thereby protecting the ultrasonic welding machine body, avoiding the swing of the ultrasonic welding machine body after the collision, resulting in loosening of the connection and falling off of the ultrasonic welding machine body, and the shaking of the ultrasonic welding machine body resulting in deviation in the position of the welding body, thereby reducing the accuracy of welding, etc.

[0017] In the present invention, the protective plate deflects after being hit, and the deflection of the bottom end can mobilize the connecting slider to slide along the second slide groove. Since the second slide grooves fit each other and the tips of the protective bottom plate are at low pressure against each other, the protective bottom plate rises as the position of the protective plate is deflected. While the connecting slider slides in the second slide groove, it drives the side of the protective bottom plate that is away from each other to tilt up, and the second spring pulls after tilting up. Therefore, the wear-resistant force of the sliding pull of the connecting slider and the pulling force of the second spring can offset the force of the collision again. When not working, the protective bottom plates are tightly attached to each other to form an enclosed space with the protective plate, which can prevent the entry of external dust and keep the main body of the ultrasonic welding machine clean.

[0018] In the present invention, during operation, the air pump is started, gas enters the air pipe, enters the directional connecting pipe along the air pipe, and then enters the fixed pipe in different directions, and finally blows air into the space formed by the protective plate through the air blowing head, and the gas is discharged downward and blown to the working ultrasonic welding machine body at the same time, so as to prevent the dust carried during work from entering the protective plate to pollute the ultrasonic welding machine body, and to blow the dust attached to the ultrasonic welding machine body. When the second electric slider moves to the side away from the air pump, the air pipe can be pulled, and the air pipe is forced to move upward to pull the fixed cylinder. The movement of the fixed cylinder drives the reset connecting block to move, and the reset connecting block drives the lifting slider to slide along the trajectory of the lifting slide groove and pull the third spring. The third spring is stretched. When the second electric slider slides to one side of the air pump, the third spring loses the pulling force and starts to rebound, and the third spring pulls the lifting slider down, and the lifting slider drives the reset connecting block to move downward, and the reset connecting block pulls the air pipe back through the fixed cylinder, so that the air pipe is extended and retracted with the movement of the second electric slider, thereby increasing convenience.

[0023] In this embodiment, the cylinder 221 is started, and the cylinder 221 pushes the ultrasonic welding machine body 222 to move downward. The ultrasonic welding machine body 222 moves downward to squeeze the protective bottom plate 234. The protective bottom plate 234 gradually deflects with the connecting slider 2342 as the axis and pulls the second spring 2344. At this time, the tip of the protective bottom plate 234 is always attached to the ultrasonic welding machine body 222. When the ultrasonic welding machine body 222 moves down to the bottom, the tip of the protective bottom plate 234 is attached to the middle of the top of the ultrasonic welding machine body 222. At this time, the ultrasonic welding machine body 222 can perform welding work. After the welding is completed, the ultrasonic welding machine body 222 retracts. During the retraction, the protective bottom plate 234 also gradually deflects in the opposite direction and squeezes the second spring 2344 until the ultrasonic welding machine body 222 completely enters the interior of the protective plate 233 and separates from the protective bottom plate 234.

The deflection of the reverse push rod 2332 can drive the fixed ring 2334 to deflect. The deflection of the fixed ring 2334 pulls the first spring 2335, and the first spring 2335 is stretched, thereby offsetting the force generated during the collision, thereby protecting the ultrasonic welding machine body 222, avoiding the swing of the ultrasonic welding machine body 222 after the collision, resulting in loosening of the connection and falling off of the ultrasonic welding machine body 222, and the shaking of the ultrasonic welding machine body 222 resulting in deviation of the position of the welding body, thereby reducing the accuracy of welding, etc.

[0024] like Figure 1 - Figure 8 As shown, the bottom protective component includes a protective bottom plate 234, and second sliding grooves 2341 are opened on both sides of the top of the protective bottom plate 234. The inside of the second sliding groove 2341 is slidably connected with a connecting slider 2342, and the middle part of the top of the connecting slider 2342 is fixedly connected with a connecting shaft 2343. The connecting shaft 2343 is rotatably connected with the connecting groove 2336.

The top of the second spring 2344 is fixedly connected to the protective plate 233.

[0025] In this embodiment, the protective plate 233 is deflected after being collided, and the deflection of the bottom end can mobilize the connecting slider 2342 to slide along the second slide groove 2341. Since the second slide grooves 2341 fit each other and the tips of the protective bottom plate 234 are at low pressure, the protective bottom plate 234 rises as the position of the protective plate 233 after deflection, and the connecting slider 2342 slides in the second slide groove 2341 while driving the side of the protective bottom plate 234 that is away from each other to tilt up, and the second spring 2344 is pulled after tilting up, so the wear resistance of the sliding pull of the connecting slider 2342 and the pulling force of the second spring 2344 can offset the collision force again. Secondly, when not working, the protective bottom plates 234 are tightly attached to each other, forming an enclosed space with the protective plate 233, which can prevent the entry of external dust and keep the ultrasonic welding machine body 222 clean.

[0026] like Figure 1 - Figure 8 As shown, the blowing assembly includes an air pump 31, which is arranged on one side of the workbench 1 close to the movable groove, and an air pipe 32 is fixedly connected to one side of the air pump 31, and an end of the air pipe 32 away from the air pump 31 is fixedly connected to a branch connecting pipe 35, and the branch connecting pipe 35 is fixedly connected to one side of the second electric slider 22, and both ends of the branch connecting pipe 35 are fixedly connected to fixed pipes 351, and the fixed pipes 351 are fixed to the two sides of the top of the fixed plate 23, and the bottom end of the fixed pipe 351 is equidistantly arranged and fixedly connected to a blowing head 352, and the blowing head 352 passes through the fixed plate 23 and is fixedly connected to the fixed plate 23, and the air pipe 32 is located at the movable groove and is slidably connected to the limiting pipe 33, and the bottom end of the limiting pipe 33 is fixedly connected to a movable connecting block 34, and the movable connecting block 34 is slidably connected to the movable groove and fixedly connected to the first electric slider 213, and the air pipe 32 is located at the limiting pipe 33 close to the air pump 31 A reset piece is provided at one end, and the reset piece includes a reset connecting block 36.

When the second electric slider 22 moves to the side away from the air pump 31, the air pipe 32 can be pulled, and the air pipe 32 is forced to move upward. The fixed cylinder 366 is pulled, and the fixed cylinder 366 moves to drive the reset connecting block 36 to move. The reset connecting block 36 drives the lifting slider 361 to slide along the trajectory of the lifting slide groove 215 and pulls the third spring 362. The third spring 362 is stretched. When the second electric slider 22 slides to one side of the air pump 31, the third spring 362 loses the pulling force and starts to rebound, and the third spring 362 pulls the lifting slider 361 to descend. The lifting slider 361 drives the reset connecting block 36 to move downward, and the reset connecting block 36 pulls the air pipe 32 back through the fixed cylinder 366, thereby realizing that the air pipe 32 is extended and retracted with the movement of the second electric slider 22, thereby increasing convenience.

The back push rod 2 The spring 2335 is stretched to offset the force generated during the collision, thereby protecting the ultrasonic welding machine body 222, preventing the ultrasonic welding machine body 222 from swinging after the collision, causing the connection to become loose and the ultrasonic welding machine body 222 to fall off, and the ultrasonic welding machine body 222 shaking, causing the position of the welding body to deviate, thereby reducing the welding accuracy, etc. The protective plate 233 is deflected after the collision, and the deflection of the bottom end can adjust the connecting slider 2342 to slide along the second slide groove 2341. Since the second slide grooves 2341 fit each other, and the tips of the protective bottom plate 234 are under pressure with each other, the protective bottom plate 234 rises with the position of the protective plate 233 after the deflection, and the connecting slider 2342 is in the second When sliding in the slide groove 2341, the side of the protective bottom plate 234 that is away from each other is driven to tilt up, and the second spring 2344 is pulled after tilting, so the wear-resistant force of the sliding pull of the connecting slider 2342 and the pulling force of the second spring 2344 can offset the collision force again. Secondly, when not working, the protective bottom plates 234 are tightly attached to each other, and can form a closed space with the protective plate 233 to prevent the entry of external dust and keep the ultrasonic welding machine body 222 clean. During operation, the air pump 31 is started, and the gas enters the air pipe 32, enters the branch connection pipe 35 along the air pipe 32, and then enters the fixed pipe 351 in a branched manner, and finally blows air into the space formed by the protective plate 233 through the blowing head 352, and the gas is discharged downward.At the same time, the ultrasonic welding machine body 222 that is working can be blown to prevent the dust carried during work from entering the protective plate 233 to pollute the ultrasonic welding machine body 222, and the dust attached to the ultrasonic welding machine body 222 can be blown. When the second electric slider 22 moves to the side away from the air pump 31, the air pipe 32 can be pulled, and the air pipe 32 is forced to move upward to pull the fixed cylinder 366. The movement of the fixed cylinder 366 drives the reset connection block 36 to move, and the reset connection block 36 drives the lifting slider 361 Slide along the track of the lifting slide 215 and pull the third spring 362, the third spring 362 stretches, when the second electric slider 22 slides to one side of the air pump 31, the third spring 362 loses its pulling force and starts to rebound, and the third spring 362 pulls the lifting slider 361 down, the lifting slider 361 drives the reset connection block 36 to move down, and the reset connection block 36 pulls the air pipe 32 back through the fixed cylinder 366, so that the air pipe 32 can be extended and retracted with the movement of the second electric slider 22, which increases convenience.
