Specifically, the first base 2 is further provided with an unfolding auxiliary mechanism 36, and the unfolding auxiliary mechanism 36 is arranged on the inner side of the arc-shaped limiting mechanism 7.

When the glass fibers 15 and the flexible material 3 need to be fed on the first base 2 positioned at the feeding station 9, the glass fibers 15 in the shape of a web are sleeved on the unfolding auxiliary mechanism 36, and meanwhile, the flexible material 3 is wrapped outside the glass fibers 15 and placed inside the arc limiting mechanism 7.

It should be noted that, as shown in fig. 12, when the flexible material 3 is placed around the outside of the glass fiber 15, the two clamping mechanisms 101 are in a third preset state, that is, in a relatively far away state, under this condition, the two ends of the flexible material 3 located inside the arc-shaped limiting mechanism 7 are bent in a relatively far away direction, and the two ends of the flexible material 3 are respectively fixed in the corresponding clamping mechanisms 101, at this time, the flexible material 3 is placed in a shape of a Chinese character 'ji', so as to avoid a dispensing space, and facilitate the subsequent dispensing operation.

In this embodiment, when the two clamping mechanisms 101 are in the third preset state, the two clamping mechanisms 101 are respectively located at the edge positions of the corresponding first guide rail 102, and at this time, the distance between the two clamping mechanisms 101 is the farthest.

The first base 2 is also provided with a limiting opening at a corresponding position of the third preset state of the two clamping mechanisms 101, so that when the clamping mechanisms 101 are in the third preset state, the second connecting piece 44 can sequentially pass through the connecting hole and the limiting opening on the first connecting piece 34 to complete limiting fixation of the corresponding clamping mechanism 101, thereby ensuring the stability of the placement of the flexible material 3 in a shape like a Chinese character 'ji'.

Before the welding process, two ends of the flexible material 3 need to be bent in opposite directions and then fixed in the corresponding clamping mechanisms 101, at this time, the clamping mechanisms 101 are in a first preset state, and the flexible material 3 has a circular arc structure; before the dispensing process, two ends of the flexible material 3 need to be far away from each other to avoid the dispensing space, so that two ends of the flexible material 3 need to be bent in a relatively far away direction and then respectively fixed in the corresponding clamping mechanisms 101, and at this time, the clamping mechanisms 101 are in a third preset state, and the flexible material 3 is in a shape like a Chinese character 'ji'.

Specifically, the dispensing mechanism 14 includes a dispensing nozzle 141 and a pressing roller 142, the dispensing mechanism 14 moves in a first preset direction under the action of the third driving mechanism 45, the pressing roller 142 is disposed in the first preset direction of the dispensing nozzle 141, an axial direction of the pressing roller 142 is perpendicular to the first preset direction, and the pressing roller 142 is used for rotationally pressing a dispensing end face of the glass fiber 15 around an axial direction thereof during the movement of the dispensing mechanism 14.

In this embodiment, the first preset direction is from bottom to top in fig. 12 and 13, and the dispensing nozzle 141 is disposed directly above the pressing roller 142. The dispensing direction of the dispensing nozzle 141 is perpendicular to the end face to be dispensed, and the axial direction of the pressing roller 142 is parallel to the end face to be dispensed. When the dispensing mechanism 14 moves from the bottom end to the top end of the end face to be dispensed of the glass fiber 15, the dispensing nozzle 141 simultaneously applies the adhesive to the contact position of the end face.

Specifically, when the glass fiber 15 and the flexible material 3 located at the feeding station 9 are switched to the dispensing station 10, the dispensing mechanism 14 approaches the end face located at the preset dispensing position under the action of the seventh driving mechanism 46, and stops when moving to the corresponding position, and at this time, the dispensing nozzle 141 is controlled to simultaneously perform the dispensing on the position where it contacts the end face.

After the first preset direction moves to a preset distance, the end face gluing process is completed, the control dispensing mechanism 14 moves to a position far away from the preset dispensing position and returns to the initial position, and at this time, the dispensing process is completed. In this embodiment, the directions of approaching the end face to be dispensed and separating from the end face to be dispensed are perpendicular to the end face to be dispensed.

Meanwhile, in the upward movement process of the dispensing mechanism 14, the pressing roller 142 above the dispensing nozzle 141 rolls around the axial direction thereof, so that the glue spreading area, which is to be reached by the dispensing nozzle 141, on the end face is pressed smoothly, so that glue spreading is more uniform and the effect is better.

simultaneously, the pressing roller 142 of the dispensing mechanism 14 rotates around the axial direction of the pressing roller during the movement of the dispensing mechanism 14 to press the end face of the glass fiber 15 to be dispensed;

when the application of the glue is completed, the control dispensing mechanism 14 moves in a direction away from the end face at the preset dispensing position and then moves in the opposite direction to the first preset direction to the initial position.

The dispensing mechanism 14 automatically returns to its initial position by setting the designated position as the dispensing beam position, and determining that the dispensing process is finished when the dispensing mechanism 14 moves to the designated position. When the sensor arranged near the initial position of the dispensing mechanism 14 detects that the dispensing mechanism 14 returns to the initial position, the rotating mechanism 8 is controlled to rotate so as to switch to the laminating and positioning station 11.

The specific production process on the laminating and positioning station 11 is as follows:

when the glass fibers 15 and the flexible material 3 at the feeding station 9 are switched to the dispensing station 10, the second web clamping structure 135 is removed from the preset dispensing position and detachably fixed on the fixing member 133;

the transfer member 132 is controlled to move on the linear guide rail 131 towards the direction of the fixing member 133 so as to align and attach the other end face of the glass fiber 15 clamped by the second web clamping structure 135 mounted on the transfer member 132 with the end face of the dispensing completion;

respectively detaching two ends of the flexible material 3 from the corresponding clamping mechanisms 101, and controlling the clamping mechanisms 101 to drive the corresponding fixed plates 1011 to move to a first preset state in opposite directions;

the auxiliary locating plate 1012 is sleeved on the corresponding limiting piece 1013 so as to absorb and fix the auxiliary locating plate 1012 on the fixing plate 1011 under the magnetic force action of the magnetic block 1014 on the auxiliary locating plate 1012, so that the flexible material 3 limited on the fixing plate 1011 is clamped and flatly stuck between the auxiliary locating plate 1012 and the fixing plate 1011, and a heating gap is formed between the two end edges of the flexible material 3.

Wherein, a sensor is arranged near the welding mechanism 4, and when the sensor detects that the heating mechanism 401 returns to the corresponding initial position, the rotating mechanism 8 is controlled to rotate so as to switch to the welding station 12.

In some other embodiments, a sensor for the position of the heating mechanism 401 after the heating is completed may also be disposed on the first base 2 near the heating gap, and when the heating mechanism 401 is detected to reach the safe position, the rotation mechanism 8 is controlled to rotate so as to switch to the welding station 12.

The specific production process at the welding station 12 is as follows:

when the glass fiber 15 and the flexible material 3 positioned at the attaching and positioning station 11 are switched to the welding station 12, the heating structure 401 of the welding mechanism 4 is controlled to extend into the heating gap to heat the edges of the two ends of the flexible material 3 simultaneously;

when the heating is finished, the heating structure 401 of the welding mechanism 4 is controlled to retract to the corresponding initial position;

the clamping mechanism 101 is controlled to move towards each other to a second preset state so as to abut the two hot-melt edges to finish the welding of the flexible material 3, so that the flexible material 3 is tightly wrapped on the outer side of the cylindrical glass fiber 15.

Example 3:

as shown in fig. 14 to 21, the embodiment of the present disclosure provides an assembling apparatus for a glass fiber filter, which includes an end cap assembling device and a spot welding device for a glass fiber filter in embodiment 2, and the glass fiber filter includes glass fibers 15, a flexible material 3, an upper end cap 16 sleeved on an upper end surface of the glass fibers, and a lower end cap 17 sleeved on a lower end surface of the glass fibers.

The assembling equipment is used for bonding the glass fiber 15 by dispensing through the dispensing welding device and welding the flexible material 3 to obtain a pre-assembled product, and then the upper end face and the lower end face of the pre-assembled product are respectively bonded with the upper end cover 16 and the lower end cover 17 through the end cover assembling device to obtain a glass fiber filter finished product.

Specifically, the end cap assembling device comprises an upper end cap assembling device and a lower end cap assembling device, wherein the upper end cap assembling device and the lower end cap assembling device both comprise a transplanting mechanism 24 and an end cap positioning mechanism, and the end cap positioning mechanism and the transplanting mechanism 24 are described by taking the upper end cap assembling device as an example.

the limiting tool 21 is arranged on the outer side of the bearing piece 18, the limiting tool 21 comprises two enclasping blocks 211, the two enclasping blocks 211 are oppositely arranged, and the two enclasping blocks 211 are pressed on the outer wall of the end cover with the positioning completed through relative movement so as to place the annular workpiece to be assembled.

In this embodiment, the end cap positioning mechanism is used to assist in completing the assembly process of the upper end cap 16 and the lower end cap 17 of the upper end cap cylindrical glass fiber, and the PP mesh coated on the outside thereof. The application takes the assembly process of the upper end cover as an example to explain the positioning principle of the end cover positioning mechanism.

It should be noted that, because the upper end cover 16 and the lower end cover 17 commonly used in the glass fiber filter are made of deformable materials, they cannot be kept in a standard circular shape, so that when the annular pre-assembled product is manually taken out on the corresponding end cover, the annular pre-assembled product cannot be placed in the end cover at one time, which makes the assembly operation difficult.

Therefore, the positioning tool 19 is arranged on the inner side of the bearing piece 18, and the limiting tool 21 is arranged on the outer side, so that the inner side and the outer side of the shape of the upper end cover 16 are limited while the positioning of the upper end cover 16 is finished, the upper end cover 16 is ensured to be in a more regular annular shape, and the annular product is conveniently and accurately placed into the upper end cover 16 to finish the assembly process.

Preferably, the outer side of the positioning block 191 includes a positioning region 1911 for positioning the end cap and a second guide region 1912 having an enlarged outer diameter in a vertical direction at an upper end of the positioning region 1911, and a length of the second guide region 1912 is greater than a length of the positioning region 1911.

Wherein the bottom dimension of the second guiding zone 1912 is larger than the dimension of the positioning zone 1911, i.e. the position of the largest dimension on the second guiding zone 1912 is in a convex configuration with respect to the positioning zone 1911. The length of the locating zone 1911 is greater than the length match of the inner wall of the upper end cap 16.

The number of the positioning blocks 191 is four, and the positioning blocks are distributed in the upper, lower, left and right directions. The number of the fourth driving mechanisms 20 is two, and the positioning blocks 191 positioned in the upper and lower directions respectively move upwards and downwards under the driving action of the same fourth driving mechanism 20; the positioning blocks 191 located in the left and right directions are moved leftward and rightward, respectively, by the driving action of the same fourth driving mechanism 20.

The positioning tool 19 is controlled to be in a first state, the upper end cover 16 after dispensing is placed on the bearing piece 18 along the second guiding area 1912 of the positioning block 191, and the positioning tool 19 is controlled to be switched from the first state to the second state so as to abut the positioning area 1911 of the positioning block 191 on the opposite position of the inner wall of the upper end cover 16 on the bearing piece 18, and the feeding process of the upper end cover 16 is completed. At this time, the maximum size position of the second guiding zone 1912 is located above the upper end cap 16.

When the positioning tool 19 is in the first state, the four positioning blocks 191 are in a gathering state; when the positioning tool 19 is in the second state, the four positioning blocks 191 are in an open state. When the positioning tool 19 is switched from the first state to the second state, the four positioning blocks 191 move upwards, downwards, leftwards and rightwards respectively, so that the positioning areas 1911 of the four positioning blocks 191 are simultaneously abutted against the relative positions of the inner wall of the upper end cover 16, the upper end cover 16 is uniformly spread in four directions, the inner wall of the upper end cover 16 is kept in a standard circular shape, and accurate positioning of the upper end cover 16 in the end cover positioning mechanism is realized.

When the four positioning blocks 191 are in a gathered state, the circular size formed by the maximum size positions on the second guiding areas 1912 of the four positioning blocks 191 is matched with the inner diameter of the upper end cover 16.

Preferably, the inside of the clasping block 211 includes a limit region 2111 for compressing the end cap and a first guide region 2112 having an inner diameter enlarged in a vertical upward direction at an upper end of the limit region 2111, and a length of the first guide region 2112 is greater than a length of the limit region 2111.

Specifically, the inner side of the limit region 2111 is in a semicircular arc shape. The bottom dimension of the first guiding region 2112 is larger than the dimension of the spacing region 2111, i.e. the maximum dimension position of the first guiding region 2112 is a convex structure relative to the spacing region 2111.

Preferably, the device further comprises a second base 23 provided with a second guide rail 22, the bearing piece 18 is fixed on the second base 23, the two enclasping blocks 211 are both in sliding connection with the second guide rail 22, and after the end cover is positioned by the positioning tool 19, the two enclasping blocks 211 relatively move along the second guide rail 22 to be pressed on the outer side of the end cover so as to limit the end cover.

Specifically, the second base 23 is provided with a rectangular slot 42, the center of the rectangular slot 42 coincides with the center of the bearing member 18, the bearing member 18 is formed by two symmetrically arranged circular arc structures, the groove design of the circular arc structures is matched with the end cover to be borne, and the rectangular slot 42 is positioned between the two circular arc structures. Wherein the length of the rectangular slot in the Y-direction is greater than the maximum width of the end cap to be carried by the carrier 18.

It should be noted that, the end cover positioning mechanism provided by the application is used for completing the positioning of the upper end cover 16 and ensuring that the upper end cover 16 is in a more regular annular shape, so that the glass fiber 15 coated with the PP net can be accurately placed into the upper end cover 16 under the limit effect provided by the end cover positioning mechanism to complete the assembly of the upper end cover and the bonding of the upper end cover.

Because glass fiber 15 is soft material, very easily damages when getting and putting the operation, need avoid the manual work directly to take or extrude it, consequently, through be equipped with rectangle fluting 42 on second base 23 for can the manual work pass rectangle fluting 42 after the glass fiber 15 of cladding PP net accomplishes the equipment of upper end cover, hold up the product from the below of upper end cover 16, so as to get the product fast and put, avoid causing the damage to glass fiber 15 manual extrusion.

After the positioning of the upper end cover 16 is completed, the two holding blocks 211 are controlled to move relatively to be pressed on the outer wall of the upper end cover 16 after the positioning is completed, and the shape limitation of the outer wall of the upper end cover 16 and the limiting function of glass fibers to be wrapped with the PP net are completed. At this time, the maximum size position of the first guiding region 2112 is located above the upper end cap 16.

In this embodiment, the two holding blocks 211 are provided with handles, and when the two holding blocks 211 are driven by the two handles to relatively move until the two holding blocks are closed, the limiting operation is completed.

In some other embodiments, the two clasping blocks 211 can be driven and controlled by corresponding driving mechanisms to synchronously move towards and away from each other.

When the positioning and limiting of the upper end cover 16 are completed under the combined action of the positioning tool 19 and the limiting tool 21, the maximum size position of the second guiding region 1912 and the maximum size position of the first guiding region 2112 are located above the upper end cover 16, at this time, the maximum size position of the second guiding region 1912 and the maximum size position of the first guiding region 2112 are located on the same horizontal plane, and the thickness of the formed ring shape between the maximum size position of the second guiding region 1912 and the maximum size position of the first guiding region 2112 is smaller than the sum of the thicknesses of the glass fiber 15 and the PP mesh.

In the process of placing the glass fibers coated with the PP mesh into the upper end cover 16 along the second guiding area 1912 and the first guiding area 2112, when the glass fibers coated with the PP mesh reach the maximum size position of the second guiding area 1912 and the maximum size position of the first guiding area 2112, the two guiding areas compress the glass fibers coated with the PP mesh into a smaller thickness, so that the glass fibers coated with the PP mesh fall into the upper end cover 16 quickly in the process of pressing down the glass fibers coated with the PP mesh, and the assembly process is completed.

Because the glass fiber is made of soft material, the cylindrical glass fiber is irregularly cylindrical, so that when the cylindrical glass fiber wrapped with the PP net is manually taken and placed on the lower end cover, the end surface shape of the cylindrical glass fiber and the shape of the groove of the lower end cover cannot be matched, and the cylindrical glass fiber cannot be placed in the lower end cover at one time, and the assembly operation is difficult.

Therefore, by collocating the first guiding region 2112 and the second guiding region 1912, a better guiding effect is achieved on the cylindrical glass fiber wrapped with the PP net to be placed in the upper end cover 16, and the upper end cover 16 of the cylindrical glass fiber which is easy to deform and soft in material can be assembled easily, so that the operation time for manually adjusting the shapes of the cylindrical glass fiber and the PP net is saved, and meanwhile, the problem that the glass fiber is damaged by manual operation is avoided.

Specifically, the transplanting mechanism 24 includes a lower pressing plate 241 located in the horizontal direction, and the transplanting mechanism 24 presses down the glass fiber 15 and the flexible material 3 sleeved outside thereof through the lower pressing plate 241 for keeping pre-pressing time so that the end surfaces of the two are bonded with the upper end cover 16 where dispensing is completed.

The upper end cover assembling device further comprises a fifth driving mechanism 25 and a sixth driving mechanism 26, wherein the fifth driving mechanism 25 is in driving connection with the transplanting mechanism 24, and the fifth driving mechanism 25 is used for driving the transplanting mechanism 24 to move in the horizontal direction; the sixth driving mechanism 26 is in driving connection with the lower pressing plate 241, for driving the lower pressing plate 241 to move in the vertical direction.

The fifth driving mechanism 25 and the sixth driving mechanism 26 are cylinders, and after the sixth driving mechanism 26 descends to enable the lower pressing plate 241 to be tightly pressed on the lower end face of the glass fiber 15 and the PP mesh coated on the outer side of the lower pressing plate, a pressing state is kept based on pre-pressing time to complete a pressure maintaining process of assembling the upper end cover. When the pre-pressing time is over, the sixth driving mechanism 26 moves upwards to return to the initial position, and the fifth driving mechanism 25 moves backwards to return to the initial position, so that the assembly process of the upper end cover of the glass fiber 15 and the PP net coated on the outer side of the glass fiber is completed.

In the present embodiment, the lower cap assembly device also includes the fifth driving mechanism 25 and the sixth driving mechanism 26, and the fifth driving mechanism 25 and the sixth driving mechanism 26 of the lower cap assembly device are configured to be identical to the fifth driving mechanism 25 and the sixth driving mechanism 26 of the upper cap assembly device, respectively, but the driving direction of the fifth driving mechanism 25 of the lower cap assembly device is different from the driving direction of the fifth driving mechanism 25 of the upper cap assembly device.

Meanwhile, because of the installation requirement of the glass fiber filter, the structural designs of the upper end cover 16 and the lower end cover 17 of the glass fiber filter in the present embodiment are different, and thus the carrier 18 in the lower end cover assembly device is different from the carrier 18 in the upper end cover assembly device.

The lower end cap assembling device further includes a pressure maintaining mechanism 27 and a conveying mechanism 28, the pressure maintaining mechanism 27 includes a pressure maintaining plate 271 having a plurality of stations, and a lower surface of the pressure maintaining plate 271 is matched with an upper surface of the upper end cap 16.

Specifically, the upper surface of the upper end cap 16 is provided with an annular protrusion structure, and thus, when the lower pressure plate 241 of the lower end cap assembly device is pressed down, it is not necessarily in complete flat contact with the upper end cap 16.

The conveying mechanism 28 is used for carrying an annular workpiece adhered with the lower end cover 17 for pressure maintaining, and the conveying mechanism 28 is used for rotating according to a discharging direction when the pressure maintaining mechanism 27 completes adhesion of the multi-station annular workpiece and the corresponding lower end cover 17 so as to convey the assembled glass fiber filter to a discharging area.
