Description

Technical Field

[0001] This invention relates to the field of strip applicator technology, and more particularly to an elastic sheet cutting mechanism for a strip applicator, a strip applicator, and a method for cutting and applicating strips. Background Technology

[0002] Flat die-cutting molds are widely used tools in the packaging industry. They use blades set on a template to cut or crease packaging materials to meet the needs of various packaging forming processes. Elastic sheets are usually attached to the die template on both sides of the blade edge to assist cutting and protect the blade.

[0003] Currently, the bonding of this elastic sheet is mainly achieved by applying adhesive to the surface of the sheet or die template. However, this method requires specialized adhesive application equipment and adds an independent adhesive application process, resulting in a complex process flow, increased production steps, and consequently affecting the efficiency of the bonding strip and increasing the overall cost.

[0091] (III) Beneficial Effects

[0092] The beneficial effects of this invention are as follows: In the elastic sheet cutting mechanism of this strip applicator, the supporting pad is bonded to the adhesive backing of the elastic sheet through a release layer attached to its top, thereby reducing the adhesive force between the pad and the adhesive. This allows the cut elastic strip to resist the adhesive force between the supporting pad and the adhesive, smoothly detaching from the supporting pad and being removed from the remaining elastic sheet. The cutting head can cut through the elastic layer and adhesive backing of the elastic sheet, so that the cut elastic strip has adhesive backing and is inherently sticky, allowing it to be directly adhered to the cutting template without the need for additional gluing treatment of the cutting template or the surface of the elastic strip. This simplifies the process, improves strip applicator efficiency, simplifies the device structure, and reduces costs. Furthermore, the supporting pad is relatively soft, so the cutting head will not damage the cutting tool when it comes into contact with the supporting pad during cutting.

[0093] The application head of this strip applicator can cleanly and completely peel the adhesive backing of the elastic strip from the supporting pad, avoiding adhesive residue or stretching deformation, ensuring the integrity of the adhesive backing, thereby improving the adhesion and positional accuracy.

[0094] The cutting head and the applying head of this strip applicator can be two independent mechanisms, and their positions are not limited. The cutting operation of the cutting head and the subsequent material picking and applying operation of the applying head can be performed independently. That is, after the cutting head cuts the elastic sheet, it uses a support pad to transfer the cut elastic sheet to the working area of ​​the applying head, where the applying head picks up and applies the strip. Of course, the cutting head and the applying head can also be two cooperating mechanisms to perform the cutting and material picking and applying operations continuously or simultaneously.

[0095] Both of these layout options enhance production flexibility and adapt to diverse process requirements: In the independent mechanism mode, cutting and strip application can be performed separately, suitable for scenarios requiring segmented control of production rhythm. The combined mechanism mode, on the other hand, supports continuous or synchronous operations, reducing material turnaround time and is suitable for efficient and consistent mass production.

[0128] Example 1

[0129] This invention provides an elastic sheet cutting mechanism for a strip applicator, which includes a support pad 12 and a cutting head 3.

[0130] See Figure 10-13 A release layer is attached to the top of the support pad 12. The top of the support pad 12 is used to support the elastic sheet 500, which includes an elastic layer 501 and an adhesive backing 502 from top to bottom, and is bonded to the adhesive backing 502. The cutting head 3 can cut through the elastic layer 501 and the adhesive backing 502 of the elastic sheet 500 supported by the support pad 12 to cut out an elastic strip 510 including the elastic layer 501 and the adhesive backing 502. The adhesive backing 502 is double-sided adhesive.

[0131] The supporting pad 12 is bonded to the adhesive 502 of the elastic sheet 500 via a release layer attached to its top. This reduces the adhesive force between the supporting pad 12 and the adhesive 502, allowing the cut elastic strip 510 to resist the adhesive force between the supporting pad 12 and the adhesive, thus smoothly detaching from the supporting pad 12 and being removed from the remaining elastic sheet. The cutting head 3 can cut through the elastic layer 501 and the adhesive 502 of the elastic sheet 500, so that the cut elastic strip 510, with the adhesive 502 attached, is inherently adhesive and can be directly pasted onto the cutting template 600 without the need for additional gluing treatment of the cutting template 600 or the surface of the elastic strip 510. This simplifies the process, improves strip application efficiency, simplifies the device structure, and reduces costs. Furthermore, the supporting pad 12 is relatively soft, so the cutting head will not damage the cutting tool when it comes into contact with the supporting pad 12 during cutting.

[0132] Preferably, the supporting pad 12 includes a bottom layer and a release layer attached to the top of the bottom layer. The bottom layer is a felt pad, a plastic pad, or includes a base paper and a coating on top of the base paper. The bottom layer is made of a relatively soft material to avoid damaging the cutting tool during the cutting process. Felt pads offer good cushioning, plastic pads are durable, and coated base paper is inexpensive. In actual use, different bottom layer materials can be selected according to different production environments and cost requirements.

[0133] The felt pad and plastic pad are coated with a release coating layer to form a release layer. The release paper consists of base paper, a coating film, and a release layer from top to bottom, and it itself has a release layer. The plastic pad can be made of materials such as polyvinyl chloride (PVC), polyethylene (PE), or polypropylene (PP).

[0134] When the bottom layer includes the base paper and the coating on top of the base paper, the base paper is preferably cardboard. The cardboard of the standard type is thicker, which can prevent the cutting head 3 from cutting through it.

[0135] Preferably, the bottom layer is made of felt, which is relatively soft and has its own ventilation holes 12111, which facilitates the subsequent connection of negative pressure to adsorb the elastic sheet 500 onto the supporting soft pad 12.

[0136] Specifically, when the bottom layer is a felt pad, the felt pad itself has ventilation holes 121. When the bottom layer is a plastic pad, or includes a base paper and a coating on top of the base paper, if it is necessary to fix the elastic sheet 500 to the supporting soft pad 12 by negative pressure adsorption, ventilation holes 121 can be evenly distributed on the bottom layer.

[0137] Preferably, the thickness of the bottom layer is at least 2mm to prevent the cutting head from cutting through the bottom layer.

[0138] Specifically, the release layer is a silicon-based release coating layer or a non-silicon-based release coating layer.

[0139] In silicone-based release coatings, the release function is primarily provided by organosilicon compounds, such as silicone resins and silicone oils. In non-silicone-based release materials, the release function is mainly provided by polymers that do not contain organosilicon, including the following categories: long-chain alkyl polymers, acrylic resins, fluorocarbon polymers, or other polyolefins (such as polymethylpentene, atactic polypropylene, etc.).

[0140] Silicone-based release coatings offer stable performance and provide good and consistent release for most adhesives, but there is a risk of siloxane oligomer migration to the adhesive interface. Non-silicone-based release coatings, on the other hand, are more selective in their application to different adhesive types, their peel strength is more sensitive to process and environmental parameters, and they meet environmental protection requirements. In practice, the most suitable release layer solution can be selected based on the specific chemical properties of the adhesive 502 on the elastic sheet 500 to ensure effective peeling.

[0141] Preferably, the release layer is a silicone-based release coating layer, specifically a silicone oil layer. Silicone oil is a mature and efficient release agent with stable performance, providing uniform and durable release force, ensuring consistent and reliable peeling of the elastic sheet 500 under different environmental conditions, and improving process stability.

[0142] Furthermore, in this embodiment, the elastic sheet 500 is fixed to the supporting pad 12 to prevent the elastic sheet 500 from shifting during the cutting and material handling processes, thereby ensuring cutting and material handling accuracy. The specific fixing method is as follows:

[0143] The support pad 12 is provided with ventilation holes 121, which can be connected to negative pressure to adsorb the elastic sheet 500 onto the support pad 12; and / or, the edge of the elastic sheet 500 can be clamped onto the support pad 12.

[0144] The negative pressure adsorption method generates a vertically downward and evenly distributed adsorption force on the elastic sheet 500, which is particularly suitable for the bearing pad 12 with its own ventilated holes. It effectively overcomes the tendency to warp and achieves flat fixation across the entire surface. The edge clamping method is particularly suitable for fixing the bearing pad 12, which is not porous and requires machining to create openings. In use, one can choose to use either negative pressure adsorption or edge clamping to fix the elastic sheet 500 to the bearing pad 12, or both methods can be used simultaneously to prevent displacement of the elastic sheet during cutting and material handling, thus ensuring cutting and material handling accuracy. Preferably, the simultaneous use of negative pressure adsorption and edge clamping, i.e., fixing both the surface and the edge simultaneously, improves the fixing effect of the elastic sheet 500.

[0145] Specifically, when the bottom layer of the supporting pad 12 is a felt pad, the felt pad itself has ventilation holes 121. When the bottom layer is a plastic pad, or includes a base paper and a coating on top of the base paper, if it is necessary to fix the elastic sheet 500 to the supporting pad 12 by negative pressure adsorption, ventilation holes 121 can be evenly distributed on the bottom layer.

[0146] Preferably, the bottom layer is made of felt, which is relatively soft and has its own ventilation holes 121, so as to facilitate the subsequent connection of negative pressure to adsorb the elastic sheet 500 onto the supporting soft pad 12.

[0147] Furthermore, this elastic sheet support mechanism also includes a support frame 11.

[0148] The support pad 12 is located on the top of the support frame 11, which supports the support pad 12 and can be placed on the frame.

[0149] Furthermore, when the elastic sheet 500 can be adsorbed onto the support pad 12, the elastic sheet support mechanism also includes a negative pressure pump 13. The negative pressure pump 13 is connected to the bottom of the support pad 12 through a pipeline and is used to output negative pressure suction to the vent holes 121 on the support pad 12 so as to adsorb the elastic sheet 500 onto the support pad 12.

[0150] Furthermore, when the edge of the elastic sheet 500 can be clamped onto the support pad 12: the support frame 11 is provided with a clamping mechanism for clamping the edge of the elastic sheet 500 onto the support pad 12.

[0151] Optionally, the clamping mechanism includes a clamping plate 142 and a locking member. The clamping plate can press against the top edge of the elastic sheet 500, and the locking member can lock the clamping plate 142 onto the support frame 11.

[0152] The locking component can be a threaded fastener or a quick-release locking pin, or other mechanisms that can achieve locking.

[0153] When the locking element is a threaded fastener or a quick-release locking pin, both the clamping plate 142 and the support frame 11 have insertion holes, and the locking element can be inserted into the insertion holes on the clamping plate 142 and the support frame 11 to lock the clamping plate 142 onto the support frame 11.

[0154] Preferably, multiple clamping mechanisms are arranged at intervals along the edge of the support frame 11 to expand the clamping range of the elastic sheet 500 edge and avoid local displacement of the elastic sheet 500.

[0155] Optionally, the clamping mechanism includes a clamping plate 142 and a lifting driver 141. The main body of the lifting driver 141 is fixed to the support frame 11, and the driving end is fixedly connected to the clamping plate 142. The lifting driver 141 is used to drive the clamping plate 142 to rise and fall, so that the clamping plate 142 presses against the edge of the elastic sheet 500.

[0156] The lifting driver 141 can be a cylinder, or it can include a motor and a transmission mechanism connected to the motor shaft, such as a gear rack, lead screw, or nut. Of course, the lifting driver 141 can also be other drivers capable of driving the clamping plate 142 to rise and fall.

[0157] Furthermore, the type of cutting head 3 is not limited, and it can include water jet, vibrating knife, air knife, laser knife and other types.

[0158] Preferably, the cutting head 3 is a vibrating blade, and the cutting blade 31 of the cutting head 3 can vibrate up and down and move horizontally relative to the elastic sheet 500, so as to cut through the elastic layer 501 and the adhesive backing 502.

[0159] Furthermore, the cutting method of the elastic sheet cutting mechanism for the strip applicator includes the following steps:

[0160] A1. A support pad 12 is configured to support an elastic sheet 500 consisting of an elastic layer 501 and an adhesive backing 502 from top to bottom. The release layer attached to the top of the support pad 12 is bonded to the adhesive backing 502.

[0161] A2. The cutting head 3 cuts the elastic sheet 500 supported by the bearing pad 12 into an elastic strip 510 including an elastic layer 501 and an adhesive backing 502.

[0162] Among them, the cutting head 3 can cut at least one elastic strip 510 in one cutting operation.

[0163] Example 2

[0164] This embodiment is a further limitation based on embodiment 1. In this embodiment, in order to support the movement of the cutting head 3, the elastic sheet cutting mechanism for the strip applicator also includes an XY axis guide rail and a slide table slidably disposed on the XY axis guide rail. The cutting head 3 is disposed on the slide table, and the slide table can drive the cutting head 3 to move horizontally relative to the elastic sheet 500 along the XY axis. The cutting blade 31 of the cutting head 3 can be raised and lowered relative to the slide table to adjust the cutting depth.

[0165] Example 3

[0166] See Figure 1-7 Based on Embodiment 1, this embodiment also provides a strip applicator, which includes the elastic sheet cutting mechanism for the strip applicator in Embodiment 1, and also includes a strip applicator head 2.

[0167] The support pad 12 supports the elastic sheet 500 with the elastic strip 510 cut out, and is bonded to the adhesive backing 502. Because a release layer is attached to the top of the support pad 12, the adhesive force between the adhesive backing 502 and the release layer is less than the adhesive force between the adhesive backing 502 and the elastic layer 501, allowing the elastic strip 510 to detach entirely from the support pad 12. Therefore, during the lifting of the elastic strip 510 by the strip applicator 2, the upward force resists the adhesive force between the adhesive backing 502 and the release layer, allowing the adhesive backing of the elastic strip 510 to detach from the support pad 12, thereby removing the elastic strip 510 from the remaining elastic sheet 500. The strip applicator 2 can also move the elastic strip 510 to adhere it to the die template 600 via the adhesive backing 502.

[0168] Therefore, the strip applicator head 2 can cleanly and completely peel the adhesive 502 of the elastic strip 510 from the supporting pad 12, avoiding adhesive residue or stretching deformation, ensuring the integrity of the adhesive, thereby improving the adhesion and positional accuracy.

[0169] Furthermore, the elastic strips 510 cut by the cutting head 3 include a first-shaped elastic strip in the form of a cuboid and a second-shaped elastic strip in an irregular shape. The two types of elastic strips 510 are adapted to different cutting and material handling methods.

[0170] See Figure 12 and 13For the first-shaped elastic strip, the cutting head 3 first cuts along one side of the elastic sheet 500 one by one; or, after cutting out a cuboid, cut the elastic strips 510 of the required length one by one, and then insert the strip head 2 into the elastic layer 501 of the elastic strip 510:

[0171] The strip head 2 moves the elastic strip 510 horizontally to resist the adhesive force between the cut backing adhesive 502 and the backing adhesive 502 of the remaining elastic sheet 500. Then, the strip head 2 lifts the elastic strip 510 upward or diagonally upward so that the backing adhesive 502 of the elastic strip 510 can be separated from the support pad 12, thereby allowing the elastic strip 510 to be removed from the remaining elastic sheet 500.

[0172] Alternatively, the adhesive strip 2 can be lifted upwards or diagonally upwards to allow the adhesive 502 on the back of the elastic strip 510 to detach from the supporting pad 12, thereby allowing the elastic strip 510 to be removed from the remaining elastic sheet 500.

[0173] For the second-shaped elastic strip, the cutting head 3 first cuts the elastic strips 510 of the required shape and size one by one inside the elastic sheet 500. Then, the strip applicator 2 is inserted into the elastic layer 501 of the elastic strip 510. Since the elastic strip 510 is located inside the elastic sheet 500 and cannot move horizontally, the strip applicator 2 directly lifts the elastic strip 510 so that the adhesive 502 of the elastic strip 510 can be separated from the supporting pad 12, thereby allowing the elastic strip 510 to be taken out from the remaining elastic sheet 500.

[0174] Preferably, the upward force applied to the elastic strip 510 by the adhesive strip head 2 can be increased by increasing the gripping force applied to the elastic layer 501, so that the upward force is sufficient to separate the adhesive 502 of the elastic strip 510 from the supporting pad 12, and the elastic strip 510 is removed from the remaining elastic sheet 500. Specific methods include: using a harder elastic layer 501, such as using an elastic material with a Shore hardness of 35 degrees or higher (e.g., sponge) (this hardness value is illustrative and not a limitation; the specific value can be determined according to actual needs); or, see [link to relevant documentation]. Figure 17 Alternatively, protrusions 211 can be provided on the peripheral wall of the pin 21 of the strip head 2. The protrusions 211 can provide a stable lifting force for gripping the elastic strip 510. Or, the number and size of the protrusions 211 provided on the peripheral wall of the pin 21 can be increased, or the protrusions 211 can be set as barbs extending obliquely upward, to further improve the gripping force of the protrusions 211 of the pin 21 on the elastic strip 510.

[0175] Furthermore, the cutting head 3 and the strip-applying head 2 can be two independent mechanisms, and their positions are not limited. The cutting operation of the cutting head 3 and the subsequent strip-applying operation of the strip-applying head 2 can be performed independently. That is, after the cutting head 3 cuts the elastic sheet 500, it uses the supporting pad 12 to transfer the cut elastic sheet 500 to the working area of ​​the strip-applying head 2, where the strip-applying head 2 performs the strip-applying operation. Of course, the cutting head 3 and the strip-applying head 2 can also be two cooperating mechanisms to perform the cutting operation and the strip-applying operation continuously or simultaneously.

[0176] Both of these layout options enhance production flexibility and adapt to diverse process requirements: In the independent mechanism mode, cutting and strip application can be performed separately, suitable for scenarios requiring segmented control of production rhythm. The combined mechanism mode, on the other hand, supports continuous or synchronous operations, reducing material turnaround time and is suitable for efficient and consistent mass production.

[0177] The specific layout method can be selected according to the actual situation.

[0178] See Figure 1 Furthermore, when the cutting head 3 and the strip-applying head 2 are two independent mechanisms, the strip-applying method of this strip-applying machine includes the following steps:

[0179] B1. A support pad 12 is configured to support an elastic sheet 500 consisting of an elastic layer 501 and an adhesive backing 502 from top to bottom. The release layer attached to the top of the support pad 12 is bonded to the adhesive backing 502. The elastic sheet 500 has been cut into elastic strips 510 including the elastic layer 501 and the adhesive backing 502.

[0180] B2. The strip head 2 moves to the support pad 12 and is inserted into the elastic layer 501 of the elastic strip 510 supported by the support pad;

[0181] Subsequently, the strip head 2 lifts the elastic strip 510 to detach it from the remaining elastic sheet 500;

[0182] Move the elastic strip 510 with the strip head 2 and stick the adhesive 502 on the back of the elastic strip 510 onto the die template 600.

[0183] See Figure 11 Specifically, step B2 also includes:

[0184] After the strip head 2 moves the elastic layer 501 of the first-shaped elastic strip horizontally, it lifts the first-shaped elastic strip upward or diagonally upward to detach it from the remaining elastic sheet 500; or, the strip head 2 lifts the first-shaped elastic strip upward or diagonally upward to detach it from the remaining elastic sheet 500.

[0185] Alternatively, the strip head 2 can be lifted upwards to detach the second-shaped elastic strip from the remaining elastic sheet 500.

[0186] In the above cutting and pasting method, the cutting head 3 can cut at least one elastic strip 510 at a time.

[0187] Example 4

[0188] See Figure 1 This embodiment is a further limitation based on embodiment 3. This embodiment provides a strip pasting machine, in which the cutting head 3 and the strip pasting head 2 are two independent mechanisms, and the model and setting position of the cutting head 3 are not limited. After the cutting head 3 cuts the elastic sheet 500, it transfers the elastic sheet 500 to the working area of ​​the strip pasting head 2, where the strip pasting head 2 performs the strip pasting operation.

[0189] To support the movement of the labeling head 2, the labeling machine also includes a first XY axis guide rail 61 and a first slide table 62 slidably disposed on the first XY axis guide rail 61.

[0190] The number of strip heads 2 is at least one. The strip head 2 is set on the first slide table 62 and the pin 21 of the strip head 2 can be raised and lowered relative to the first slide table 62. The strip head 2 can move along the first XY axis guide rail 61 to the bearing pad 12 and the blade template 600.

[0191] The elastic sheet 500 supported by the support pad 12 has been cut into elastic strips 510. The adhesive strip head 2 can detach the adhesive 502 of the elastic strip 510 from the support pad 12, thereby removing the elastic strip 510 from the remaining elastic sheet 500, and moving the elastic strip 510 to stick it to the die template 600 through the adhesive 502.

[0192] Specifically, when the number of strip applicator heads 2 is at least two: when at least two strip applicator heads move to the support pad 12, at least two elastic strips 510 can be sequentially removed from the elastic sheet 500. When at least two strip applicator heads move to the die template 600, the adhesive 503 of at least two elastic strips 510 can be sequentially adhered to the die template 600. This reduces the movement path of the strip applicator heads 2 and improves material handling and strip application efficiency. Here, "at least two" and "more than two" includes two or more.

[0193] The strip applicator 2 can move along the first XY axis guide rail 61 on the X and Y axes and can adjust the cutting depth of the insert pin 21 by raising and lowering it to pick up materials and apply strips.

[0194] Furthermore, this strip applicator also includes a frame 5. The first XY axis guide rail 61, the support frame 11 at the bottom of the support pad 12, and the strip applicator table 4 for supporting the blade template 600 are all located on the top of the frame 5.

[0195] Example 5

[0196] See Figure 2 This embodiment is a further limitation based on embodiment 3. This embodiment provides a strip applicator, wherein the cutting head 3 and the strip applicator 2 are two cooperating mechanisms, and the cutting head 3 and the strip applicator 2 are integrated on a moving guide rail to continuously perform cutting operations and material picking and strip applicator operations.

[0197] To support the movement of the cutting head 3 and the strip applicator head 2, this strip applicator includes a second XY axis guide rail 71 and a second slide table 72 slidably mounted on the second XY axis guide rail 71.

[0198] The cutting head 3 and at least one applicator head 2 are both mounted on the second slide table 72. The cutting blade 31 of the cutting head 3 and the insert pin 21 of the applicator head 2 can be raised and lowered independently relative to the second slide table 72. The second slide table 72 can drive the cutting head 3 and the applicator head 2 to move synchronously to the supporting pad 12 and the blade template 600. The cutting head 3 and the applicator head 2 can perform cutting and applicator strip picking operations in sequence. Therefore, by integrating the cutting head 3 and the applicator head 2 onto one slide table, the overall size of the applicator machine can be reduced.

[0199] Specifically, when the number of adhesive strip heads 2 is at least two, at least two adhesive strip heads 2 can be taken out sequentially and the adhesive 503 of at least two elastic strips 510 can be pasted onto the die template 600. This improves the efficiency of material picking and adhesive strip application.

[0200] The cutting head 3 and the strip-applying head 2 can move along the second XY axis guide rail 71 on the X and Y axes and can be raised and lowered to adjust their positions for cutting and strip application.

[0201] Furthermore, this strip applicator also includes a frame 5. The second XY axis guide rail 71, the support pad 12 at the bottom of the support pad 12, and the strip applicator table 4 for supporting the blade template 600 are all located on the top of the frame 5.

[0202] Furthermore, the strip-cutting and strip-applying method of the strip-applying machine in this embodiment includes the following steps:

[0203] C1. A support pad 12 is configured to support an elastic sheet 500 consisting of an elastic layer 501 and an adhesive backing 502 from top to bottom. The release layer attached to the top of the support pad 12 is bonded to the adhesive backing 502.

[0204] C2. The cutting head 3 and the stripping head 2 move synchronously to the bearing pad 12;

[0205] The cutting head 3 cuts the elastic sheet 500 supported by the cushion 12 into an elastic strip 510, which includes an elastic layer 501 and an adhesive backing 502.

[0206] Subsequently, the strip head 2 is inserted into the elastic layer 501 of the elastic strip 510 supported by the support pad 12; the strip head 2 lifts the elastic strip 510 to detach it from the remaining elastic sheet 500.

[0207] C3, the cutting head 3 and the strip attaching head 2 move synchronously to the blade template 600, and the strip attaching head 2 attaches the elastic strip 510 to the blade template 600 with the adhesive backing 502.

[0208] In the above cutting and pasting method, the cutting head 3 can cut at least one elastic strip 510 at a time.

[0209] Example 6

[0210] See Figure 3-7 This embodiment is a further limitation based on embodiment 3. In the strip applicator provided in this embodiment, the cutting head 3 and the strip applicator head 2 are two mechanisms that cooperate with each other and move independently, so as to perform cutting operations and strip applicator operations simultaneously. At the same time, the supporting soft pad 12 is movably configured, and the supporting soft pad 12 can move the elastic sheet 500 to be cut to the cutting station 300, and move the cut elastic sheet 500 to the picking station 400.

[0211] The number of supporting pads 12 is at least one. When the number of supporting pads 12 is at least two: at least two supporting pads 12 can move independently of each other; or, at least two supporting pads 12 can move synchronously and are located at the cutting station 300 and the material picking station 400 respectively.

[0212] The cutting head 3 can cut elastic strips 510 from the elastic sheet 500 supported by the support pad 12 located at the cutting station 300. The strip attaching head 2 can remove the elastic strips 510 from the elastic sheet 500 supported by the support pad 12 located at the material picking station 400.

[0213] Based on the above settings, this labeling machine can achieve the following effects:

[0214] This application enables parallel operation of multiple processes. The cutting head 3, which performs the cutting process, and the strip-applying head 2, which performs the material picking and pasting process, are set up independently. The elastic sheet 500 is moved to the cutting station 300 and the material picking station 400 via the support pad 12. This arrangement allows: when only one support pad 12 is set, after the strip-applying head 2 picks up the elastic sheet 500 supported by the support pad 12 at the material picking station 400, the cutting head 3 performs the cutting operation on the elastic sheet 500 supported by the support pad 12 at the cutting station 300, while the strip-applying head 2 performs at least the material transfer and pasting operations. When at least two or more support pads 12 are provided: while the cutting head 3 performs a cutting operation on the elastic sheet 500 supported by one support pad 12 located at the cutting station 300, the strip attaching head 2 performs a strip attaching operation that includes picking up, transferring, and attaching the elastic sheet 500 supported by another support pad 12 located at the picking station 400. Thus, the cutting operation performed by the cutting head 3 can be performed in parallel with the strip attaching operation performed by the strip attaching head 2, which includes at least transferring and attaching the strip, and the cutting operation and the strip attaching operation do not interfere with each other, achieving synchronous operation.

[0215] Improve overall strip application efficiency: The support pad 12 can transfer the elastic sheet 500 to the cutting station 300 and the material picking station 400. With the coordinated operation of the cutting head 3 and the strip application head 2, the cutting and strip application processes can be carried out in cycles, reducing or even eliminating the waiting time between processes and significantly improving the overall strip application efficiency.

[0216] Improve the continuity of the strip application process: The strip application head 2 can directly take out the pre-cut elastic strip 510 from the bearing pad 12 of the material picking station 400 and transfer it to the knife template, realizing continuous automated operation from cutting to pasting and ensuring the continuity of the strip application process.

[0217] Enhanced equipment flexibility and adaptability: The bearing pad 12 can support elastic sheets 500 of different sizes and shapes, the cutting head 3 can cut elastic strips 510 of any size and shape as needed, and the strip attaching head 2 can adapt to different material picking and pasting paths, enabling the device to flexibly meet various production needs.

[0218] Optimize space and workstation utilization: By moving the support pad 12 between the cutting station 300 and the material picking station 400, and by moving the strip head 2 between the material picking station 400 and the blade template, the efficient reuse of limited workstations is achieved, and multi-step processing is completed in a compact structure, saving equipment space.

[0219] Furthermore, this strip applicator also includes a frame 5. A support pad 12 is movably mounted on top of the frame 5 via a bottom support pad 12. A strip applicator table 4 for supporting the blade template 600 is mounted on the frame 5.

[0220] Furthermore, the strip-cutting and strip-applying method of the strip-applying machine in this embodiment includes the following steps:

[0221] D1. At least one support pad 12 is configured, on which an elastic sheet 500 including an elastic layer 501 and an adhesive backing 502 are supported from top to bottom. The release layer attached to the top of the support pad 12 is bonded to the adhesive backing 502.

[0222] D2. The support pad 12 can move the elastic sheet 500 to be cut to the cutting station 300; the cutting head 3 performs a cutting operation on the elastic sheet 500 supported by the support pad 12 located at the cutting station 300. The cutting operation includes: the cutting head 3 cuts the elastic sheet 500 supported by the support pad 12 located at the cutting station 300 into an elastic strip 510 including an elastic layer 501 and an adhesive backing 502.

[0223] The support pad 12 can also move the cut elastic sheet 500 to the picking station 400; the strip applicator 2 performs picking and applicating operations on the elastic strip 510 supported by the support pad 12 located at the picking station 400; the picking operation includes: the strip applicator 2 inserts into the elastic layer 501 of the elastic strip 510 supported by the support pad 12 located at the picking station 400; then, the strip applicator 2 lifts the elastic strip 510 to detach it from the remaining elastic sheet 500; the applicating operation includes: the strip applicator 2 moves the removed elastic strip 510 and sticks the adhesive 502 of the elastic strip 510 to the cutting template 600.

[0224] Specifically, in the strip-cutting and strip-applying method of the strip-applying machine in this embodiment, when the number of supporting pads 12 is one,

[0225] Step D1 also includes: configuring a support pad 12;

[0226] Step D2 also includes:

[0227] D21, The supporting soft pad 12 moves the elastic sheet 500 to be cut to the cutting station 300; the cutting head 3 performs cutting operation on the elastic sheet 500 supported by the supporting soft pad 12 located at the cutting station 300.

[0228] Subsequently, the supporting soft pad 12 moves the cut elastic sheet 500 to the material picking station 400;

[0229] D22, the strip head 2 performs a material picking operation on the elastic strip 510 supported by the bearing pad 12 located at the material picking station 400;

[0230] D23. Simultaneously perform the following steps:

[0231] D231, the bearing pad 12 moves the elastic sheet 500 after all the cut elastic strips 510 have been removed to the cutting station 300, and the cutting head 3 cuts the elastic sheet 500 supported by the bearing pad 12 at the cutting station 300 again; the bearing pad 12 moves the cut elastic sheet 500 to the material picking station 400.

[0232] D232, Sticker Head 2, perform the sticker application operation;

[0233] D24. Repeat steps D22-D23 until all the strip positions on the knife template 600 have been covered with elastic strips 510.

[0234] Specifically, step D231 also includes:

[0235] When all the cut elastic strips 510 on the elastic sheet 500 supported by the supporting pad 12 have been removed and there is no remaining cutting position on the elastic sheet 500, the supporting pad 12 moves to the cutting station 300 and replaces the new elastic sheet 500.

[0236] Specifically, in the strip-cutting and strip-applying method of the strip-applying machine in this embodiment, when the number of supporting pads 12 is at least two,

[0237] Step D1 also includes: configuring at least two support pads 12;

[0238] Step D2 also includes:

[0239] D21, the support pad 12 moves the elastic sheet 500 to be cut to the cutting station 300; the cutting head 3 cuts the elastic sheet 500 supported by the support pad 12 at the cutting station 300; then, the support pad 12 moves the cut elastic sheet 500 to the material picking station 400.

[0240] D22. Simultaneously perform the following steps:

[0241] D221, the strip attaching head 2 performs material picking and strip attaching operations on the elastic strip 510 supported by the bearing pad 12 located at the material picking station 400;

[0242] D222, the cutting head 3 performs cutting operations on the elastic sheet 500 supported by at least one other bearing pad 12 located at the cutting station 300;

[0243] Subsequently, the supporting soft pad 12 moves the cut elastic sheet 500 to the material picking station 400;

[0244] D23. Repeat step D22 until all the strip positions on the knife template 600 have been covered with elastic strips 510.

[0245] Preferably, when the number of supporting pads 12 is at least two,

[0246] Step D22 also includes:

[0247] D223. When all the cut elastic strips 510 on the elastic sheet 500 supported by the bearing pad 12 have been removed and the elastic sheet 500 still has a cutting position, the bearing pad 12 drives the elastic sheet 500 after all the cut elastic strips 510 have been removed to the cutting station 300.

[0248] Preferably, when the number of supporting pads 12 is at least two,

[0249] Step D22 also includes:

[0250] D224. When all the cut elastic strips 510 on the elastic sheet 500 supported by the bearing pad 12 have been removed and there is no remaining cutting position on the elastic sheet 500, the bearing pad 12 moves to the cutting station 300 and replaces the new elastic sheet 500.

[0251] In the above cutting and pasting method, the cutting head 3 can cut at least one elastic strip 510 at a time.

[0252] Example 7

[0253] See Figure 3-5 This embodiment is a further limitation based on embodiment 6. In order to support the movement of the supporting cushion 12, this embodiment further limits the following:

[0254] The strip applicator includes an X-axis guide rail 811, on which cutting stations 300 and material handling stations 400 are arranged at intervals along the X-axis.

[0255] At least one support pad 12 is provided, and the support pad 12 is slidably disposed on the corresponding X-axis guide rail 811. When at least two support pads 12 are provided, the at least two support pads 12 are arranged at intervals along the Y-axis and can move independently of each other.

[0256] Thus, at least two supporting pads 12 can move independently of each other and their movement paths do not interfere with each other, so that the cutting head can continuously cut the elastic sheet supported by different supporting pads 12, and the stripping head can continuously pick up and apply strips, reducing the waiting time of the process and improving the stripping efficiency.

[0257] Specifically, the bottom of the support pad 12 is fixedly connected to the fifth slide, and is slidably mounted on the X-axis guide rail via the fifth slide.

[0258] Furthermore, to support the movement of the cutting head 3, this embodiment further specifies that the strip applicator also includes at least one first Y-axis guide rail 812.

[0259] See Figure 4 When the number of first Y-axis guide rails 812 and cutting heads 3 is one, the first Y-axis guide rail 812 is arranged at the cutting station 300. The cutting head 3 is slidably mounted on the first Y-axis guide rail 812 via a third slide table 851, and the cutting blade 31 of the cutting head 3 can rise and fall relative to the third slide table 851. The cutting head 3 can move to any of the bearing pads 12 located at the cutting station 300 to cut the elastic sheet 500 supported by the bearing pad 12 into elastic strips 510. Based on the above configuration, one cutting head 3 can perform cutting operations on any bearing pad 12 moved to the cutting station 300, thereby simplifying the structure and reducing the overall machine size. Furthermore, the cutting head 3 can continuously cut the elastic sheet 500 supported by different bearing pads 12 to improve cutting efficiency and thus improve strip application efficiency.

[0260] See Figure 5 When at least two first Y-axis guide rails 812 and cutting heads 3 are provided, at least two first Y-axis guide rails 812 and X-axis guide rails 811 correspond one-to-one and are arranged at the cutting station 300. At least two cutting heads 3 are slidably mounted on the first Y-axis guide rails 812 via third slides 851, and the cutting blades 31 of the cutting heads 3 can be raised and lowered relative to the third slides 851. At least two cutting heads 3 can cut the elastic sheet 500 supported by the bearing pad 12 located at the cutting station 300. The cutting head 3 is set to at least two and cuts independently. At least two cutting heads 3 can simultaneously cut different elastic sheets 500. When one cutting head 3 is cutting and the strip pasting head 2 has completed the material picking and pasting operation, the other cutting head 3 can cut the elastic sheet 500 after all the cut elastic strips 510 have been taken out, so as to carry out simultaneous or continuous cutting operations. This can speed up the cutting efficiency, shorten the waiting time of the material picking head 52, shorten the waiting time between processes, and improve the strip pasting efficiency of the whole machine.

[0261] The cutting head 3 can move along the first Y-axis guide rail 812 relative to the bearing pad 12 located at the cutting station 300 on the Y-axis. The bearing pad 12 can move along the X-axis guide rail 811 relative to the cutting head 3 on the X-axis. That is, the cutting head 3 can move relative to the bearing pad 12 along the X and Y axes, and the cutting blade 31 of the cutting head 3 can be raised and lowered to adjust the cutting depth. Thus, the cutting head 3 can cut the elastic sheet 500 carried by the bearing pad 12.

[0262] Specifically, the X-axis guide rail 811 and the first Y-axis guide rail 812 are both mounted on the frame 5.

[0263] Example 8

[0264] See Figure 6 This embodiment is a further limitation based on embodiment 6. In order to support the movement of the bearing pad 12 and the cutting head 3, this embodiment further limits: the strip applicator includes a rotary table 821 and at least one third XY axis guide rail 822.

[0265] The rotary table 821 is vertical in axis, and at least one cutting station 300 and a material picking station 400 are set at intervals around the axis of the rotary table 821 on the rotary support surface (i.e., frame 5).

[0266] The number of supporting pads 12 is at least two, and the at least two supporting pads 12 are arranged at circumferential intervals on the top of the rotary table 821. The rotary table 821 can drive the at least two supporting pads 12 to rotate synchronously around the vertical axis to the cutting station 300 and the material picking station 400 respectively.

[0267] When the number of the third XY axis guide rail 822, the cutting head 3, and the cutting station 300 is one, the third XY axis guide rail 822 is arranged corresponding to the cutting station 300, and the third slide table 851 is slidably arranged on the third XY axis guide rail 822, and the cutting head 31 of the cutting head 3 can be raised and lowered relative to the corresponding third slide table 851. Based on the above configuration, one cutting head 3 can perform cutting operations on any of the bearing pads 12 that have moved to the cutting station 300, thereby simplifying the structure and reducing the overall size of the machine. Furthermore, the cutting head 3 can continuously cut the elastic sheet 500 carried by different bearing pads 12, thereby improving the cutting efficiency and thus improving the strip application efficiency.

[0268] When at least two third XY axis guide rails 822, cutting heads 3, and cutting stations 300 are provided, the at least two third XY axis guide rails 822 are arranged circumferentially and correspond one-to-one with the cutting stations 300. Third slides 851 are slidably mounted on the third XY axis guide rails 822, and at least two cutting heads 3 are correspondingly mounted on the third slides 851, with the cutting blades 31 of the cutting heads 3 able to rise and fall relative to the corresponding third slides 851. The at least two cutting heads 3 can simultaneously cut the elastic sheet 500 supported by the bearing pad 12 located at the cutting station 300, thereby accelerating cutting efficiency, shortening the waiting time for the material pick-up head 52 to pick up material, reducing inter-process waiting time, and improving the overall strip-applying efficiency of the machine.

[0269] The cutting head 3 can move along the third XY axis guide rail 822 on the X and Y axes relative to the bearing pad 12 located at the cutting station 300 and can adjust the cutting depth of the cutting head 31 to cut the elastic sheet 500 supported by the bearing pad 12.

[0270] Specifically, the rotary table 821 and the third XY axis guide rail 822 are both mounted on the frame 5. The support platform at the bottom of the bearing pad 12 is mounted on the rotary table 821.

[0271] Specifically, the main body of the rotary motor is mounted on the frame 5, and the drive end is fixedly connected to the rotary table 821. The rotary table 821 is rotatably connected to the frame 5 via bearings. The rotary motor is used to drive the rotary table 821 to rotate around the vertical axis.

[0272] Example 9

[0273] See Figure 7 This embodiment is a further limitation based on embodiment 6. In order to support the movement of the bearing pad 12 and the cutting head 3, this embodiment further limits: the strip applicator includes a second Y-axis guide rail 831.

[0274] The cutting station 300 includes a first cutting station 300 and a second cutting station 300. The first cutting station 300, the material handling station 400, and the second cutting station 300 are arranged at intervals along the Y-axis on the second Y-axis guide rail 831.

[0275] At least two supporting pads 12 are synchronously slidably disposed on the second Y-axis guide rail 831 and can move to the first cutting station 300 and the material picking station 400 respectively; or, to the second cutting station 300 and the material picking station 400 respectively.

[0276] The number of cutting heads 3 is at least two, and the at least two cutting heads 3 are respectively arranged at the first cutting station 300 and the second cutting station 300, so as to cut the elastic sheet 500 supported by the bearing pad 12 located at the first cutting station 300 and the second cutting station 300 in a one-to-one correspondence. The at least two cutting heads 3 can perform cutting operations simultaneously or continuously, thereby speeding up the cutting efficiency, shortening the waiting time of the picking head 52 to pick up the material, shortening the waiting time between processes, and improving the overall strip-applying efficiency of the machine.

[0277] It should be noted that the number of the first cutting station, the second cutting station, and the material handling station 400 mentioned above is at least one.

[0278] Based on the above settings, at least one supporting pad 12 exists at the first cutting station and the second cutting station to enable continuous cutting operation of the cutting head 3, thereby accelerating the cutting efficiency and shortening the waiting time of the material picking head 52 to shorten the waiting time between processes, so as to improve the overall strip application efficiency of the machine.

[0279] Specifically, the support frame 11 at the bottom of the support pad 12 is slidably mounted on the second Y-axis guide rail 831 via the fifth slide table 853.

[0280] Furthermore, the labeling machine also includes at least two fourth XY axis guide rails 832.

[0281] At least two fourth XY axis guide rails 832 are located at the first cutting station 300 and the second cutting station 300 respectively, and a third slide table 851 is slidably arranged on each of the at least two fourth XY axis guide rails 832.

[0282] At least two cutting heads 3 are disposed on corresponding third slides 851 and the cutting blades 31 of the cutting heads 3 can be raised and lowered relative to the corresponding third slides 851. At least two cutting heads 3 can move along the fourth XY axis guide rail 832 on the X and Y axes relative to the bearing pad 12 located at the first cutting station or the second cutting station, and can raise and lower to adjust the cutting depth so as to simultaneously cut the elastic sheet 500 supported by the bearing pad 12 located at the cutting station 300.

[0283] Specifically, the second Y-axis guide rail 831 and the fourth XY-axis guide rail 832 are both mounted on the frame 5.

[0284] Example 10

[0285] This embodiment is a further limitation based on embodiments 7-9. In order to support the movement of the strip applicator head 2, the strip applicator also includes a fifth XY axis guide rail 841 whose movement stroke covers the material picking station 400 and the knife template 600.

[0286] The sticker head 2 is slidably mounted on the fifth XY axis guide rail 841 via the fourth slide table 852.

[0287] The number of strip-applying heads 2 is at least one. Therefore, the strip-applying heads 2 can be moved to the bearing pad 12 and the cutting template 600 located at the material picking station 400. When the number of strip-applying heads 2 is at least two, at least two strip-applying heads 2 are set on the fourth slide table 852 and the pins 21 of the strip-applying heads 2 can be raised and lowered independently relative to the fourth slide table 852.

[0288] Based on the aforementioned guide rails that support the movement of the bearing pad 12, the cutting head 3, and the strip attaching head 2, and the arrangement of the bearing pad 12 moving between the cutting station 300 and the material taking station 400, the cutting operation of the cutting head 3 and the material taking operation of the strip attaching head 2 can be made mechanically independent, so as to realize multi-process parallel operation.

[0289] Preferably, all of the above guide rails are ball screw guide rails to ensure their rigidity and running accuracy.

[0290] Specifically, the fifth XY axis guide rail 841 is mounted on the frame 5.

[0291] Preferably, in each embodiment, the supporting pad 12 and the guide rail for supporting the movement of the cutting head 3 are arranged on the top of one area of ​​the frame 5, and the fifth XY axis guide rail 841 and the blade template 600 are arranged on the top of another area of ​​the frame 5, so that the movement of the cutting head 3 and the strip head 2 does not interfere with each other.

[0292] Of course, the supporting pad 12 and the guide rail for supporting the movement of the cutting head 3 can also be set on one frame 5, and the fifth XY axis guide rail 841 and the blade template 600 can be set on the top of another frame 5 or correspondingly set on the top of two other frames 5.

[0293] Example 11

[0294] This embodiment further defines the cutting head 3 and the stripping head 2 based on embodiments 1-10.

[0295] The cutting depth of the cutting head 31 is adjustable so that the cutting head 31 can cut through the elastic layer 501 and the adhesive backing 502 of the elastic sheet 500.

[0296] Preferably, the cutting head 31 of the cutting head 3 is capable of vibrating up and down and moving horizontally relative to the elastic sheet 500, so as to cut through the elastic layer 501 and the adhesive backing 502.

[0297] It should be noted that even if the adhesive 502 on the cut elastic strip 510 is not completely cut through, there is still a joint with the adhesive 502 on the remaining elastic sheet 500. As long as the upward force after the strip head 2 is inserted into the elastic layer 501 of the elastic strip 510 is large enough, the adhesive 502 can be completely torn along the cutting path, and the integrity of the adhesive 502 on the removed elastic strip 510 can be guaranteed.

[0298] Specifically, the cutting head 3 is mounted on the second slide 72 or the third slide 851. The cutting blade 31 of the cutting head 3 can be raised and lowered relative to the second slide 72 or the third slide 851 to adjust the cutting depth of the cutting head 3 and enable the cutting blade 31 to cut through the elastic layer 501 and the adhesive backing 502 of the elastic sheet 500.

[0299] See Figure 14-15 Specifically, the cutting head 3 includes a cutting blade 31, a blade holder 5101, a driving element 5102, a rotary seat 5104, a first motor 5105, a first pressure plate 5106, a cutting bracket 5108, a cutting base plate 5109, and a second motor 5110.

[0300] The cutting head 31 is disposed at the bottom of the cutter holder 5101. The cutter holder 5101 is rotatably and vibratingly disposed on the rotary seat 5104. The cutter holder 5101 can drive the cutting head 31 to rotate relative to the rotary seat 5104 around a vertical axis to adjust the blade orientation of the cutting head 31 and change the cutting direction of the cutting head 31. The cutter holder 5101 can also drive the cutting head 31 to vibrate up and down relative to the rotary seat 5104.

[0301] The main body of the drive element 5102 is mounted on the rotary seat 5104, and the drive end is connected to the cutter holder 5101. The drive element 5102 is used to drive the cutter holder 5101 to drive the cutting head 31 to vibrate up and down. The drive element 5102 is a drive element such as a vibrating motor or a pneumatic component.

[0302] The main body of the first motor 5105 is fixed on the rotary seat 5104, and its drive end is connected to the cutter holder 5101. The first motor 5105 drives the cutter holder 5101 to rotate around the vertical axis, and the cutter holder 5101 drives the cutting head 31 to rotate synchronously. Synchronous pulleys are respectively provided on the drive end of the first motor 5105 and the cutter holder 5101, and a first synchronous belt 51051 is sleeved on the two synchronous pulleys. When the drive end of the first motor 5105 rotates, it drives the cutter holder 5101 to rotate around the vertical axis through the transmission between the synchronous pulleys and the first synchronous belt 51051.

[0303] The first pressure plate 5106 is elastically set at the bottom of the rotary seat 5104 by means of a spring that can move up and down. A window 5107 is provided in the middle of the first pressure plate 5106, and the cutting head 31 is located in the window 5107.

[0304] A cutting bracket 5108 is fixedly mounted on a first slide table 54. A vertical guide rail is arranged on the cutting bracket 5108. A cutting base plate 5109 is slidably mounted on the vertical guide rail via the slide table. A rotary seat 5104 is fixed to the cutting base plate 5109. The main body of a second motor 5110 is fixed to the cutting bracket 5108, and its drive end is connected to the cutting base plate 5109. The second motor 5110 is used to drive the cutting base plate 5109 to rise and fall. The cutting base plate 5109 drives the first pressure plate 5106 and the cutting head 31 to synchronously adjust their height positions via the rotary seat 5104.

[0305] In this embodiment, when the first pressure plate 5106 presses down onto the elastic sheet 500 to be cut, if the cutter holder 5101 continues to press down, the distance between the first pressure plate 5106 and the rotary seat 5104 will shorten as the pressure reaches a certain level, and the cutting head 31 will insert into the elastic sheet 500. The driving element 5102 drives the cutter holder 5101 to vibrate up and down, thereby causing the cutting head 31 to vibrate up and down. When the cutting head 31 is inserted into the elastic sheet 500 with up and down vibration, the cutting head 31 can move relative to the elastic sheet 500 along the X and Y axes, and the cutting head 31 can rotate around the vertical axis to adjust the blade orientation of the cutting head 31 and change the cutting direction of the cutting head 31. Thus, the cutting of the elastic sheet 500 can be achieved.

[0306] See Figure 16-17Furthermore, to improve the lifting force of the adhesive strip head 2 on the elastic strip 510, it is preferable to provide a protrusion 211 on the peripheral wall of the pin 21 of the adhesive strip head 2. The pin 21 can be inserted into the elastic layer 501 of the elastic strip 510 supported by the support pad 12 and lift the elastic strip 510. At this time, the protrusion 211 can provide a stable lifting force to grasp the elastic strip 510, so as to drive the adhesive 502 of the elastic strip 510 to detach from the support pad 12 and separate from the elastic sheet 500.

[0307] Furthermore, the strip head 2 is disposed on the first slide 62, the second slide 72 or the fourth slide 852, and the pin of the strip head 2 can be raised and lowered relative to the slide to adjust the depth of the pin inserted into the elastic sheet 500.

[0308] Specifically, the structure of sticker head 2 is as follows:

[0309] The labeling head 2 includes a mounting base 5121, a material picking motor 5122, a rotating fixed seat 5123, a material picking and dispensing body 5124, a pin assembly, a stripping plate 51261, a second pressing plate 51262, a dispensing cylinder, and a material picking rotary motor 51283.

[0310] The mounting base plate 5121 is fixedly mounted on the fourth slide table 852. A vertical slide rail is provided on the mounting base plate 5121, and a slide table 5127 is slidably mounted on the vertical slide rail.

[0311] The main body of the pick-up motor 5122 is fixed on the mounting base plate 5121, and the output shaft is connected to the slide table 5127. The pick-up motor 5122 is used to drive the slide table 5127 to move up and down along the fourth slide table 852.

[0312] The rotating fixed base 5123 is fixedly connected to the slide table 5127.

[0313] The material handling body 5124 is rotatably mounted on the rotating fixed base 5123.

[0314] The pin assembly is located at the bottom of the material handling body 5124 and includes at least one pin 21.

[0315] The main body of the discharge cylinder is fixed on the rotating fixed base 5123, and the drive end is connected to the stripping plate 51261. The discharge cylinder is used to drive the stripping plate 51261 to move up and down and is located below the material handling body 5124. The stripping plate 51261 has a space for the pin assembly to pass through. The discharge cylinder is located at the top of the material handling body 5124, and a connecting rod is provided through the material handling body 5124. One end of the connecting rod is connected to the cylinder shaft of the discharge cylinder, and the other end of the connecting rod is connected to the stripping plate 51261.

[0316] The main body of the pressing cylinder 512821 is fixed on the rotating fixed base 5123, and the driving end is connected to the second pressing plate 51262. The pressing cylinder 512821 is used to drive the second pressing plate 51262 to move up and down and is located below the material picking and dispensing body 5124. The second pressing plate 51262 is provided with a second clearance space for the unloading plate 51261 to pass through.

[0317] The main body of the rotary motor 51283 is fixedly connected to the rotating fixed base 5123. Both the rotating shaft of the rotary motor 51283 and the loading / unloading body 5124 are equipped with synchronous pulleys, and a second synchronous belt 5129 is fitted onto the two synchronous pulleys. When it is necessary to adjust the arrangement direction of multiple pins 21 in the pin assembly to match the extension direction of the elastic strip 510 cut from the supporting pad 12, thereby inserting the pin assembly into the elastic strip 510, the rotary motor 51283 drives the loading / unloading body 5124 to rotate around the vertical axis via the second synchronous belt 5129, thus achieving the deflection of the arrangement direction of the pin assembly.

[0318] When the elastic strip needs to be grasped, the material-grabbing motor 5122 drives the slide table 5127 to move downwards, thereby moving the rotating fixed seat 5123 mounted on the slide table 5127. The material-grabbing body 5124 follows and moves downwards, and the pin 21 is inserted into the elastic strip 510. When the rectangular elastic strip 510 needs to be moved horizontally, the pin 21 can move horizontally under the action of the first slide table 62, the second slide table 72, or the fourth slide table 852, so as to move the elastic sheet 500 horizontally to detach from the adhesive 502 of the remaining elastic sheet 500. The pressure cylinder 512821 drives the second pressure plate 51262 to move downwards. The second pressure plate 51262 presses on other elastic sheets 500 that do not need to be grasped, preventing other elastic sheets 500 from moving upwards after the elastic strip being grasped. The material handling motor 5122 drives the slide table 5127 to move upward, and the pin 21 moves upward along with it. The elastic sheet 500 on the pin 21 also moves upward. Due to the action of the second pressure plate 51262, the remaining elastic sheet 500 stays in the original position.

[0319] When the material handling head 512 moves to the position above the elastic sheet 500 that needs to be attached to the cutting template 600, the elastic sheet 500 needs to be lowered. The material handling cylinder is activated, the cylinder shaft of the material handling cylinder extends, and the connecting rod moves downward, so that the stripping plate 51261 pushes the elastic sheet 500 on the insert pin 21 downward, so that the elastic sheet 500 is pressed against the cutting template 600.

[0320] Example 12

[0321] See Figure 18This embodiment is a further limitation based on embodiments 1-11. The strip applicator also includes a detection head 9, which is used to detect the height and position of the blade template 600 carried by the strip applicator table 4 relative to the strip applicator table 4, so as to obtain the cutting position of the cutting head 3 and the strip picking and lifting position of the strip applicator head 2. The detection head can be of various types, including mechanical, laser, and vision types.

[0322] Preferably, the detection head 9 is mechanical.

[0323] In Example 3, the detection head 9 is mounted on the first slide 62. In Example 4, the detection head is mounted on the second slide 72. In Example 9, the detection head 9 is mounted on the fourth slide 852.

[0324] Specifically, the detection head 9 includes a detection base plate 5111, a detection slide 5112, a detection motor 5113, a first rotary cylinder 5114, a first rotary cylinder 5115, a detection rod 5116, and a probe 5117.

[0325] The detection base plate 5111 is fixedly mounted on the first slide table 62, the second slide table 72 or the fourth slide table 852, and the detection base plate 5111 is provided with a vertical slide rail.

[0326] The detection slide 5112 is slidably mounted on the vertical slide rail on the detection base plate 5111, so that the entire detection head 9, except for the detection base plate 5111, can be raised and lowered relative to the first slide 62, the second slide 72, or the fourth slide 852.

[0327] The detection motor 5113 is fixed on the detection base plate 5111, and the output shaft of the detection motor 5113 is fixedly connected to the detection slide 5112.

[0328] The first rotary cylinder 5114 is fixedly connected to the detection slide 5112, and the first rotary cylinder 5114 is horizontally set.

[0329] The first rotary cylinder 5115 is fixedly connected to the rotating end of the first rotary cylinder 5114, and the output shaft of the first rotary cylinder 5115 is horizontally set.

[0330] The detection rod 5116 is fixedly connected to the output shaft of the first rotary cylinder 5115.

[0331] One end of the detection rod 5116 is provided with a probe 5117, and the other end of the detection rod 5116 is provided with a roller 5118.

[0332] When detecting the slit position of the cutting template 600, the probe 5117 slides across the slit. During this process, the detection end of the probe 5117 gradually enters and leaves the slit, and the height of the detection end changes depending on the contact position with the slit. This is synchronously driven by the detection rod 5116 to rotate the first rotary cylinder 5115, causing an angular change in the rotation axis of the first rotary cylinder 5115 relative to its initial position. The angular change curve is read; the peak of the curve corresponds to the lowest value of the detection end's height. The XY value of the detection end corresponding to this lowest value is a point on the centerline of the slit. Repeated scrolling obtains the centerline parameters of the slit. The centerline parameters of at least two intersecting slits are compared with the slit parameters on the cutting template in the database embedded in the device to obtain the actual position of the current cutting template and slit.

[0333] When detecting the blade height of the blade template 600, the rolling wheel 5118 rolls on the blade. The height of the rolling wheel 5118 changes according to the blade height. This change in height of the rolling wheel 5118 synchronously drives the rotating shaft of the first rotary cylinder 5115 to rotate via the detection rod 5116. The rotating shaft of the first rotary cylinder 5115 changes angle relative to its initial position. By reading the angle change curve, the actual parameters of the blade height at different positions are obtained, thereby determining whether the blade height meets the requirements.
