This equipment includes a mounting seat, a conveying mechanism, a glue pressing mechanism and a glue cutting mechanism. The conveying mechanism is used to convey the tape; the glue pressing mechanism includes a first glue pressing part and a second glue pressing part. The first glue pressing part presses the end of the tape against the battery cell, and due to the relative movement between the mounting seat and the battery cell, the tape is bonded to the battery cell, and the second glue pressing part rolls the tape bonded to the battery cell; the glue cutting mechanism cuts off the tape between the first glue pressing part and the second glue pressing part. The free end of the mounting plate is provided with a support platform bent upward, and a gap is formed between the bottom end of the support platform and the first glue pressing part, and the tape extending out of the conveying block can pass through the gap. A vacuum adsorption part is provided in the conveying block to absorb the tape to prevent the tape from moving back and forth during shearing. The lower surface of this tape has glue, so it can be rolled directly onto the surface to be pasted. However, in other working conditions, a non-glue film needs to be pasted. This film can only become sticky when it is heated and melted, so as to achieve adhesion to the surface to be pasted. Otherwise, the film tape will fall off, and the above equipment cannot complete this operation.

[0004] Therefore, it is necessary to provide a new adhesive film tape mechanism to solve the above problems. Summary of the invention

[0005] The main purpose of the utility model is to provide a gap-type hot air film-sticking mechanism, which can stick the adhesive film strip to the surface to be stuck with the assistance of hot air, and has high working efficiency.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: a gap-type hot air film laminating mechanism, comprising a mounting plate and a cache roller group, a material pulling assembly, a shearing assembly, a material guide, a glue pressing roller assembly and a hot air assembly arranged on the mounting plate; the cache roller group is arranged on the upper part of the mounting plate; the glue pressing roller assembly comprises a downward pressure cylinder connected to the mounting plate and a glue pressing roller driven by the downward pressure cylinder; a material guide groove is provided on the material guide along the conveying direction of the glue film tape, and the outlet of the material guide groove is located below the glue pressing roller; the hot air assembly comprises a hot air gun that generates hot air and a slit-type air outlet that guides the hot air to be discharged from the bottom of the material guide; the shearing assembly comprises a pneumatic scissors located on the feeding side of the material guide and a clamping cylinder that drives the pneumatic scissors to cut the film tape.

[0007] Specifically, the cache roller group includes a plurality of rollers and a slider roller, the rollers include two high-position reversing wheels, the mounting plate is provided with a vertical long hole located between the two high-position reversing wheels, the back of the vertical long hole is provided with a vertical slide rail, and the slider roller rises and falls in the area of ​​the vertical long hole and cooperates with the vertical slide rail.

[0008] Specifically, the pulling assembly includes a pulling cylinder fixed to the back of the mounting plate, an inclined slider driven by the pulling cylinder, a suction clamp fixed to the front of the inclined slider, and a suction joint arranged on the suction clamp. The mounting plate is provided with an inclined slide rail whose length direction is parallel to the axis of the pulling cylinder. The suction surface in the suction clamp is inclined downward, and the inclined slider slides along the inclined slide rail. The suction clamp is a pair of clamps arranged closely together, and a narrow gap is provided between the two clamps for allowing only one film tape to pass through, wherein the lower surface of the upper clamp is the suction surface.

[0009] Furthermore, the mounting plate is provided with an oblique long hole whose length direction is parallel to the axis of the pulling cylinder, the oblique slide rail is located on the back of the oblique long hole, and the suction clamp passes through the oblique long hole to the front of the mounting plate.

[0010] Specifically, a flow meter for detecting the hot air flow is provided on the back side of the mounting plate.

[0011] The beneficial effects of the technical solution of the utility model are:

[0028] The utility model is further described in detail below in conjunction with specific embodiments.

[0029] Example:

[0030] like Figure 1 As shown, a gap-type hot air laminating mechanism 1 of the utility model comprises a mounting plate 11 and a buffer roller assembly 12, a material pulling assembly 13, a shearing assembly 14, a material guide 15, a glue pressing roller assembly 16 and a hot air assembly 17 arranged on the mounting plate 11.

[0031] like Figure 3 As shown, the cache roller group 12 is arranged on the upper part of the mounting plate 11, including a plurality of rollers 121 and a slider roller 122. The roller 121 includes two high-position reversing wheels 121a. The mounting plate 11 is provided with a vertical long hole 111a located between the two high-position reversing wheels 121a. The back of the vertical long hole 111a is provided with a vertical slide rail 112a. The slider roller 122 rises and falls in the area of ​​the vertical long hole 111a and cooperates with the vertical slide rail 112a.

[0032] When feeding, the film tape 2 will bypass each roller 121 and the slider roller 122, and then reach the material pulling assembly 13. According to the principle of the pulley, as long as the gravity of the slider roller 122 is higher than twice the pulling force, the slider roller 122 will tend to fall, so that a length of the film tape 2 is cached between the two high-position reversing wheels 121a, and the film tape 2 will always be kept in a taut state. When the installation vertical plate 11 is moved toward the material pulling assembly 13, the cached film tape 2 is actively sent out, and the slider roller 122 rises under the action of the tension of the film tape 2. When the material reaches the end point, the tension of the film tape 2 becomes smaller again, and the slider roller 122 descends along the vertical slide rail 112a under the action of gravity to cache the next section of the film tape 2.

[0033] like Figures 2 to 4 As shown, the material pulling assembly 13 includes a material pulling cylinder 131 fixed to the back of the mounting vertical plate 11, an inclined slider 132 driven by the material pulling cylinder 131, an air suction clamp 133 fixed to the front of the inclined slider 132, and an air suction joint 134 provided on the air suction clamp 133. The air suction surface in the air suction clamp 133 is inclined downward. The air suction clamp 133 is a pair of clamps arranged closely together. There is a narrow gap between the two clamps that only allows one film strip 2 to pass through, and the lower surface of the upper clamp is the air suction surface. The mounting vertical plate 11 is provided with an inclined long hole 111b and an inclined slide rail 112b whose length direction is parallel to the axis of the material pulling cylinder 131. The inclined slide rail 112b is located on the back of the inclined long hole 111b. The inclined slider 132 slides along the inclined slide rail 112b, and the air suction clamp 133 passes through the inclined long hole 111b to the front of the mounting vertical plate 11.

[0034] The material pulling cylinder 131 is used to indirectly drive the suction clamp 133 to move in the direction of the inclined slide rail 112b, and the suction joint 134 is used to provide the suction clamp 133 with suction to adsorb the film strip 2 on the lower surface. The suction direction of the suction clamp 133 is perpendicular to the moving direction of the suction clamp 133, so it can play a role in pulling the film strip 2. When the film strip 2 passes through the slit, by changing whether the suction joint 134 generates suction, it is possible to switch whether the suction clamp 133 keeps moving synchronously with the middle of the film strip 2. The inclined slide rail 112b is arranged on the back of the mounting vertical plate 11 to avoid the problem of excessive concentration of parts on the front, making the layout of parts more reasonable.

[0035] like Figure 3 and Figure 4 As shown, the glue pressing roller assembly 16 includes a downward pressing cylinder 161 connected to the mounting plate 11 and a downward pressing glue pressing roller 162 driven by the downward pressing cylinder 161. The material guide member 15 is provided with a material guide groove 151 along the conveying direction of the adhesive film tape 2, and the outlet of the material guide groove 151 is located below the glue pressing roller 162.

[0036] The adhesive film strip 2 will pass through the pulling component 13 in an oblique direction, and the material guide groove 151 will support the adhesive film strip 2 from the bottom and limit the adhesive film strip on both sides. The glue pressing roller 162 will press the front section of the adhesive film strip 2 downward onto the surface to be pasted. As the pasting progresses, the glue pressing roller 162 will roll the adhesive film strip 2, and with the assistance of the hot air component 17, the entire adhesive film strip 2 will be pasted onto the surface to be pasted.

[0037] like Figure 3 and Figure 4 As shown, the hot air assembly 17 includes a hot air gun 171 for generating hot air and a slit-type air outlet 172 for guiding the hot air to be discharged from the bottom of the material guide 15 , and a flow meter 18 for detecting the hot air flow is provided on the back of the mounting plate 11 .

[0038] When the front section of the adhesive film strip 2 is rolled on the surface to be laminated by the adhesive roller 162, the hot air gun 171 can heat the adhesive film strip 2 through the slit air outlet 172 to partially melt it, thereby generating adhesiveness. When the adhesive film strip 2 cools down again, it can adhere to the surface to be laminated. The flow meter 18 is used to detect the flow rate of hot air to prevent the adhesive film strip 2 from being completely melted or even burned due to excessive hot air blowing, thereby failing to achieve the pasting effect.

[0039] like Figure 3 As shown, the cutting assembly 14 includes a pneumatic scissors 141 located at the feeding side of the material guide 15 and a clamping claw cylinder 142 that drives the pneumatic scissors 141 to cut the film tape 2.

[0040] When the pulling component 13 pulls the film tape 2 to the limit, most of the front section of the film tape 2 has been attached to the surface to be attached, and only a short section of the film tape 2 is left between the material guide 15 and the suction clamp 133. At this time, the pneumatic scissors 141 can cut the film tape 2.

[0041] The use process of the intermittent hot air film laminating mechanism 1 is as follows: the operator first passes the film strip 2 around the buffer roller group 12, passes through the middle of the suction clamp plate 133, the middle of the pneumatic scissors 141, the top of the material guide groove 151 and sticks it to the lower part of the glue pressing roller 162, and the downward pressure cylinder 161 drives the glue pressing roller 162 to press down, so that the head end of the film strip 2 is pressed on the surface to be laminated, and the slider roller 122 naturally droops to the lower part of the vertical slide rail 112a under the action of gravity, so that a section of the film strip 2 is cached; at this time, the suction clamp block 33 is at a high position in the upper right corner, and then the suction joint 134 generates suction so that the middle section of the film strip 2 is sucked by the suction clamp plate 133; hot air is generated in the hot air gun 171 and blown to the head end of the film strip 2 from the slit air outlet 172, and the flow meter 18 The air outlet speed is controlled within a suitable range; the entire intermittent hot air laminating mechanism 1 moves in the opposite direction of the film strip 2 delivery direction. At the same time, the pulling cylinder 131 drives the suction clamp 133 to move obliquely downward at the conveying speed of the film strip 2. During this process, the buffered film strip 2 is conveyed to the outlet of the guide member 15, the slider roller 122 rises, and the front section of the film strip 2 is rolled onto the surface to be laminated. When the suction clamp 133 moves to the lowest point close to the pneumatic scissors 141, the intermittent hot air laminating mechanism 1 stops moving and the hot air gun 171 stops working; the slider roller 122 falls back, and then the suction clamp 33 stops suctioning, and the suction clamp 33 returns to a high position to re-absorb the upper part of the film strip 2. The above steps are repeated to perform cyclic laminating.

[0042] The intermittent hot air laminating mechanism 1 can make the film tape 2 pass through the gap between the glue pressing roller 162 and the material guide groove 151 under the traction of the pulling component 13. With the assistance of the hot air provided by the hot air gun 171, the glue pressing roller 162 sticks the film tape 2 to the surface to be laminated, and then the pneumatic scissors 141 cuts off the middle part of the pasted film tape 2. The laminating quality is stable and the working efficiency is high.

[0043] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
