Description

Technical Field

[0001] The invention relates to the technical field of workpiece welding, and in particular to a semipermeable membrane punching integrated ultrasonic welding device. Background Art

[0002] In the traditional semipermeable membrane ultrasonic welding production process, the membrane supplier needs to place the rolled semipermeable membrane raw material on the cutting equipment, cut the raw material membrane into circular membrane sheets according to the size and specifications required by the customer, and then paste the cut membrane sheets onto the plastic tape, and then roll the plastic tape with the membrane onto a hollow reel; finally, the circular membrane material reel is sold to the customer as a finished product. The customer needs to purchase a circular membrane reel tape. Before welding, it is necessary to use special equipment to peel the membrane off the plastic tape, and then use a robot to pre-install the membrane on the corresponding air permeable hole of the plastic workpiece, and then use the transport chain to transfer the workpiece covered with the membrane to the welding equipment, and then use the ultrasonic welding equipment for welding. In this traditional production line, five types of equipment, including membrane loading equipment (or manual loading), robot pre-assembly equipment, CCD camera detection equipment, ultrasonic welding equipment, and intermediate auxiliary transportation devices, are required to complete the entire production process. This traditional production method has many process steps, which increases the probability of poor welding quality. For example, during the welding process, when the semipermeable membrane is pre-installed on the welding hole, there will be a certain probability of deviation, that is, the relative position of the membrane and the hole is poorly aligned, and the probability of product NG will be greatly increased. Secondly, the welding production time of a single product is about 6 seconds, and the production efficiency is low. If the customer order volume is sufficient, it is necessary to increase investment in more production lines. The use of semipermeable membrane punching and integrated welding equipment for production increases the reliability of welding quality, reduces the welding production time of a single product to less than 2 seconds, and also reduces the floor space occupied by the equipment in the workshop.

[0003] In addition, the traditional welding method is to place the workpiece to be welded in the designated welding area, and then the welding head is lowered for welding. In this process, there is no alignment and clamping device for the workpiece. For some cases where the diaphragm and the workpiece welding holes are small, and generally the diaphragm and the welding hole are of similar size, if the position of the workpiece is slightly offset, the diaphragm will deviate from the welding hole, resulting in a decrease in welding quality or even welding failure, resulting in the failure to ensure the uniformity of the workpiece welding quality, and reducing the workpiece welding and finished product efficiency. In addition, when the workpiece is generally circular or square, the welding hole is located in the center of the workpiece. At this time, as long as the clamps are moved synchronously around, the welding position can be located at the bottom of the welding head. However, if the workpiece is rectangular or of different lengths, clamping at the same time will result in one side of the workpiece not being clamped, and the adaptability is insufficient. Summary of the invention

DETAILED DESCRIPTION

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0038] Example 1, reference Figure 1-Figure 5, which is the first embodiment of the present invention, provides a semipermeable membrane punching integrated ultrasonic welding device, including a welding table 1 and a box body installed on the welding table 1, and a workpiece 11 placed on the welding table 1, and also includes a punching and welding assembly installed in the middle of the box body; the punching and welding assembly includes a feed wheel 12 and a discharge wheel 13 installed on one side of the punching and welding assembly, a plurality of transmission rollers installed on the front position of the box body, a material belt 14 rotatably connected to the feed wheel 12 and the discharge wheel 13 and the transmission rollers, and a punching assembly 2 installed on the other side of the punching and welding assembly; the punching assembly 2 includes a punching cylinder 21 installed inside the punching assembly 2, a welding head 22 fixedly connected to the bottom of the punching cylinder 21, a fixing plate 23 fixedly connected to the bottom of the welding head 22, and a punching module 2 installed at the bottom of the fixing plate 23. 4, and rotating rollers 25 symmetrically rotatably connected on both sides of the punching module 24; a negative pressure hole 26 is opened inside the welding head 22, a punching hole 27 is opened at the bottom of the punching module 24, and an alignment unit is installed at the bottom of the punching module 24; the alignment unit is used for centering welding of the workpiece 11 placed on the welding table 1 during the welding process of the punching assembly 2 after the punching strip 14; the alignment unit includes a pressing component 3 installed on one side of the punching cylinder 21, lateral alignment components symmetrically installed on both sides of the bottom of the pressing component 3, and vertical alignment components symmetrically installed on both sides of the lateral alignment components; the pressing component 3 includes a mounting plate 31 fixedly connected to one side of the bottom of the punching cylinder 21, a protective component 32 installed at the bottom of the mounting plate 31, and a pressing plate 33 fixedly connected to the bottom of the protective component 32.

[0039] Specifically, during operation, the semipermeable membrane coil is assembled onto the turntable feeding device of the equipment, the feed wheel 12 is used to rotate the discharge material, and the discharge wheel 13 is used to reel in the coil that has been punched and cut. The automatically programmed turntable feeding device automatically delivers the semipermeable membrane strip 14 to the punching position, and the semipermeable membrane strip 14 is driven by the transmission roller to the bottom of the punching assembly 2. The equipment is equipped with a welding head 22 and a punching module 24 with an integrated punching and welding design. The welding head 22 and the punching module 24 work together to achieve the slitting of the semipermeable membrane. During punching, the punching cylinder 21 pushes the welding head 22 moves down, and the translucent material strip 14 is punched in the punching module 24. The welding head 22 uses the air negative pressure function to absorb the punched circular diaphragm. The welding head 22 passes through the punching hole 27 and aligns with the hole of the target plastic workpiece 11, and directly pre-installs the diaphragm on the hole of the workpiece 11. Then, the welding action is performed. After the welding is completed, the turntable feeding device automatically controls the material strip 14 to move through an appropriate displacement. At the same time, the auxiliary handling device moves the welded product out of the welding station, and the above process is repeated to achieve the diaphragm welding of the next product. During the downward pressure welding process after punching, the punching assembly 2 continues to move downward, so that the welding head 22 drives the semi-permeable membrane strip 14 to weld the workpiece 11, and drives the alignment unit to move downward together, and the downward pressure component 3 drives the lateral alignment component to laterally align the workpiece 11. The punching cylinder 21 is used to punch and weld the strip 14. After the punching is completed, it continues to move downward, so that the punching cylinder 21 drives the mounting plate 31 and the lower pressure plate 33 to move downward together. When the lateral alignment component abuts against the welding table 1, the punching cylinder 2 1 continues to push the welding head 22 downward, so that the mounting plate 31 is pushed down and moved downward by the protective component 32. At this time, the two lateral alignment components are aligned horizontally. When the lateral alignment components are aligned, that is, the two lateral alignment components no longer move, the vertical alignment components are pushed and moved to vertically align the workpiece 11. The workpieces 11 are aligned one after another, which can improve the alignment accuracy and meet the alignment requirements of workpieces 11 of various shapes, especially the alignment requirements of workpieces 11 of strip shape. The use of semi-permeable membrane punching integrated welding equipment for production increases the reliability of welding quality, effectively reduces the welding production time of a single product, and also reduces the floor space occupied by the equipment in the workshop, thereby improving production efficiency.

[0040] Example 2, reference Figure 5 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the protection component 32 includes a lower pressure cylinder 321 fixedly connected to the bottom of the mounting plate 31, a protection member 322 fixedly connected to the inside of the lower pressure cylinder 321, and a lower pressure rod 323 fixedly connected to the bottom of the protection member 322, and the lower pressure rod 323 is slidably connected to the inner wall of the lower pressure cylinder 321.

[0041] Specifically, the protection component 32 is used to protect the workpiece 11 during the alignment process. When the punching and welding assembly is still in the process of moving down during welding, if the vertical alignment component has been aligned, the punching and welding assembly will still move down. At this time, the vertical alignment component and the horizontal alignment component will no longer move. At this time, the lower pressure rod 323 will compress the protection component 322. The protection component 322 can be a spring. In this way, the vertical alignment component can be prevented from hard squeezing of the workpiece 11, thereby avoiding damage to the workpiece 11. Therefore, the vertical alignment component can meet the alignment requirements of strip workpieces 11 of various widths.

[0042] Reference Figure 1-Figure 7 The lateral alignment component includes a lateral alignment component 4 installed on one side of the bottom of the lower pressing plate 33, a locking component 5 symmetrically installed on both sides of the lateral alignment component 4, an unlocking component 6 installed on one side of the locking component 5, and a limiting component 7 symmetrically installed on both sides of the extrusion strip; the lateral alignment component 4 includes a lower pressing strip 41 fixedly connected to one side of the bottom of the lower pressing plate 33, a lateral alignment plate 42 slidably connected to the bottom of the lower pressing strip 41, a lower pressing hole 43 opened in the lateral alignment plate 42, and the lower pressing strip 41 and the lower pressing hole 43 is slidably connected, a moving hole 44 is opened on one side of the lower pressure hole 43, and limiting grooves 45 are symmetrically opened on both sides of the top of the moving hole 44, abutting against an extrusion block 46 on one side of the bottom of the lower pressure strip 41, and limiting strips 47 are symmetrically fixedly connected on both sides of the extrusion block 46, and the limiting strips 47 are slidably connected to the limiting grooves 45, an extrusion piece 48 is fixedly connected to one side of the extrusion block 46, and one side of the extrusion piece 48 is fixedly connected to one side of the moving hole 44, and one side of the two limiting strips 47 abut against the two locking components 5 respectively.

[0043] Specifically, the punching assembly 2 continues to move downward after punching, driving the translucent material strip 14 for welding. When the two lateral alignment components 4 are squeezed onto the workpiece 11, the unlocking component 6 is squeezed to unlock the locking component 5 to achieve vertical alignment of the workpiece 11. When the lower pressing bar 41 is pressed down, the lower pressing bar 41 moves in the lower pressing hole 43. At this time, the extrusion block 46 is abutted by the locking component 5, so that the two transverse alignment plates 42 move synchronously toward the workpiece 11. When the transverse alignment plate 42 moves a certain distance toward the workpiece 11, the unlocking component 6 starts to squeeze the workpiece 11, and the locking component 5 unlocks the abutment limit of the limit bar 47. At this time, the two transverse alignment plates 42 are no longer squeezed toward the middle, and the lower pressing bar 41 continues to move downward, which will squeeze and push the extrusion block 46 to move horizontally in the moving hole 44, and drive the limit bars 47 on both sides to move in the limit grooves 45, and the extrusion piece 48 is compressed. The extrusion piece 48 can be a spring. The extrusion piece 48 applies thrust to the transverse alignment plate 42, so that the transverse alignment plate 42 can continue to maintain the alignment and extrusion of the workpiece 11.

[0044] Reference Figure 1-Figure 8The locking assembly 5 includes a locking groove 51 opened inside the transverse alignment plate 42 and located at the bottom of the limiting groove 45, a locking piece 52 fixedly connected in the locking groove 51, a locking column 53 fixedly connected to the top of the locking piece 52, and an unlocking groove 54 opened on one side of the bottom of the locking column 53, and one side of the bottom of the unlocking groove 54 abuts against the unlocking assembly 6.

[0045] Specifically, when the locking assembly 5 is in the original state, one side of the locking column 53 abuts against the limiting strip 47, so that the extrusion strip and the extrusion block 46 are abutted and locked. When the unlocking assembly 6 squeezes the unlocking groove 54, the unlocking column moves downward and compresses the unlocking piece 61, thereby realizing the unlocking of the extrusion strip by the unlocking column.

[0046] Reference Figure 1-Figure 8 The unlocking assembly 6 includes an unlocking member 61 slidably connected to the middle of the transverse alignment plate 42, and the unlocking member 61 is in a Ʊ shape, and an unlocking rod 62 fixedly connected to one side of the unlocking member 61, and one side of the unlocking rod 62 abuts against the bottom of the unlocking groove 54.

[0047] Specifically, the workpiece 11 squeezes the unlocking member 61 so that the unlocking member 61 pushes the unlocking rod 62 to squeeze the unlocking groove 54, thereby causing the unlocking column to move downward to achieve the unlocking function. The Ʊ shape of the unlocking member 61 can increase the extrusion contact area and increase the stability of movement during the positioning extrusion process.

[0048] Reference Figure 7 The limiting assembly 7 includes a sliding groove 71 opened on one side of the extrusion strip, and a limiting rod 72 slidably connected in the sliding groove 71, and the limiting rod 72 is slidably connected in the limiting groove 45.

[0049] Specifically, the limiting assembly 7 is used to prevent the lateral positioning component from being separated from the lower pressing bar 41 during the upward movement of the positioning unit. When the lower pressing bar 41 moves downward or rightward, the limiting rod 72 moves in the sliding groove 71 or the limiting groove 45. The rest of the structure is the same as that of the first embodiment.

[0050] Example 3, reference Figure 1-Figure 9 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the vertical alignment component includes a vertical alignment component 8 installed at the bottom of one side of the horizontal alignment plate 42, and an extrusion component 9 installed on the vertical alignment component 8; the vertical alignment component 8 includes a moving groove 81 opened at the bottom of the horizontal alignment plate 42, a support plate 82 fixedly connected to both sides of the moving groove 81, a vertical alignment plate 83 slidably connected to the support plate 82, a support hole 84 opened on the vertical alignment plate 83, and one end of the vertical alignment plate 83 is slidably connected to the support plate 82 through the support hole 84, and a movable groove 85 opened on one side of the top of the support plate 82.

[0051] The extrusion assembly 9 includes a displacement groove 91 opened at the bottom of the movable groove 85, a displacement plate 92 slidably connected in the displacement groove 91, an extrusion hole 93 penetrating the displacement plate 92, an extrusion rod 94 abutting in the extrusion hole 93, and the bottom of the extrusion rod 94 is fixedly connected to the bottom of one side of the limiting strip 47, a pushing rod 95 fixedly connected to one side of the displacement plate 92, and a pushing groove 96 opened at the top of the support plate 82, and the bottom of one side of the pushing rod 95 is slidably connected to the pushing groove 96.

[0052] Specifically, during the lateral alignment process, when the extrusion block 46 is locked, the lateral alignment plate 42 drives the support plate 82, the extrusion block 46, the extrusion bar, and the extrusion rod 94 to move together, and the support plate 82 drives the push rod 95 to move synchronously through the push groove 96, thereby synchronously pushing the displacement plate 92 to move together, so that the extrusion rod 94 and the displacement plate 92 move synchronously, and the extrusion rod 94 and the extrusion hole 93 will not produce relative displacement. When the two lateral alignment plates 42 no longer move, that is, when the extrusion block 46 is unlocked and limited, the lower pressure bar 41 pushes the extrusion block 46 to move right in the moving hole 44, and the extrusion bar drives the extrusion rod 94 to move in the extrusion hole 93, that is, the extrusion rod 94 and the extrusion hole 93 produce relative displacement. At this time, the displacement plate 92 pushes the vertical alignment plate 83 in the displacement groove 91 to move toward the workpiece 11, and at the same time drives the push rod 95 to move in the push groove 96, so as to realize the vertical alignment clamping function of the workpiece 11. The remaining structures are the same as those of Example 2.

[0053] The working principle of the present invention is as follows: the material strip 14 is punched out by the punching assembly 2, the circular semipermeable membrane after punching is adsorbed by the negative pressure of the welding head 22, and in the process of continuing to press down, the lower pressing strip 41 slides in the lower pressing hole 43, so that the two horizontal alignment plates 42 perform horizontal alignment on the workpiece 11. When the unlocking member 61 is aligned and extruded into the workpiece 11, the unlocking member 61 is pushed, and the unlocking member 61 pushes the unlocking rod 62 to squeeze the unlocking groove 54 so that the locking column 53 moves downward, thereby unlocking the abutment limit of the extrusion block 46. At this time, the lower pressure bar 41 continues to move downward, and the lower pressure bar 41 moves downward to push the extrusion block 46 to move. The movement of the extrusion block 46 pushes the extrusion member 48 to continue to apply an extrusion force to the horizontal alignment plate 42, so that the horizontal alignment plate 42 continues to maintain the alignment and extrusion. At this time, the extrusion block 46 drives the extrusion bar and the extrusion rod 94 to squeeze the displacement block, so that the displacement block can push the vertical alignment plate 83 to vertically align and extrude the workpiece 11. When the horizontal alignment is completed, the accuracy and efficiency of the vertical alignment can be improved.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be included in the scope of the claims of the present invention.
