[0002] In the packaging process of small workpieces such as precision hardware, the combination of carrier tape and cover tape is a common packaging method. The workpiece is placed in the receiving groove on the carrier tape, and then covered with cover tape and the two are tightly combined by hot pressing, bonding or other technical means to achieve fixation and protection of the workpiece.

[0003] However, to prevent the cover tape from sticking during production, storage and transportation, a certain amount of anti-sticking agent, such as talcum powder, is usually added to the surface of the cover tape. However, if impurities such as talcum powder are not completely removed, they will remain between the cover tape and the carrier tape when they are connected, affecting the firmness and sealing of the connection. An unstable connection may cause the package to loosen or break during subsequent processing or transportation, thereby threatening the safety of the workpiece. Secondly, these impurities may also directly contact the surface of the workpiece, causing pollution and affecting product quality.

[0004] The above shortcomings need to be improved. Utility Model Content

[0027] like Figures 1 to 3 As shown, a release mechanism for cleaning the cover tape described in one embodiment of the utility model includes a frame 1, a reel 2 for placing the cover tape roll 8 is rotatably connected to the frame 1, the reel 2 rotates to release the cover tape 801, a first cleaning component 3 is arranged on the tape walking path of the cover tape 801, and the first cleaning component 3 contacts the cover tape 801 to clean the cover tape 801.

[0028] During the packaging process, the cover tape roll 8 to be used is first installed on the unwinding disk 2, and the unwinding disk 2 can rotate smoothly. As the production line starts, the cover tape 801 is pulled, and the unwinding disk 2 rotates driven by the cover tape 801. The first cleaning component 3 is in close contact with the surface of the cover tape 801, and removes impurities such as talcum powder attached to the surface of the cover tape 801 by friction or adsorption. Compared with the non-contact cleaning method, the cleaning force is greater and the cleaning effect is better. As the cover tape 801 continues to move, the cleaning process continues to ensure that the surface of the cover tape 801 has been fully cleaned before it is combined with the carrier tape.

[0029] In this embodiment, the cleanliness of the cover tape 801 during the packaging process is improved by providing the first cleaning component 3. On the one hand, impurities such as talcum powder that may exist on the surface of the cover tape 801 are removed, thereby preventing these impurities from affecting the connection quality between the cover tape and the carrier tape, and improving the firmness and sealing of the packaging. On the other hand, the clean surface of the cover tape 801 reduces the possible contamination of the workpiece during packaging, improves the appearance of the product, protects the quality of the workpiece, and reduces the defective rate of the product.

[0030] like Figure 1As shown, in a preferred embodiment, the first cleaning component 3 includes a first cleaning roller 302 in contact with the first surface of the cover tape 801 and a second cleaning roller 304 in contact with the second surface of the cover tape 801, a first spindle 301 is provided on the frame 1, the first cleaning roller 302 is rotatably mounted on the first spindle 301, a first connecting frame 307 is provided on the first spindle 301, a second spindle 303 is provided on the first connecting frame 307, and the second cleaning roller 304 is rotatably mounted on the second spindle 303.

[0031] When the cover tape 801 travels along the tape path, the first cleaning roller 302 and the second cleaning roller 304 are respectively located on both sides of the cover tape 801, and the first cleaning roller 302 and the second cleaning roller 304 roll on the surface of the cover tape 801, and use the adhesion of the roller surface to remove impurities on both sides of the cover tape 801. The first cleaning roller 302 and the second cleaning roller 304 clean the two sides of the cover tape 801 respectively, effectively avoiding the cleaning blind area that may be caused by unilateral cleaning, ensuring the cleanliness of the entire surface of the cover tape 801, ensuring the stability and reliability of the cleaning process, reducing the packaging quality problems caused by uneven cleaning, improving the overall quality of the packaged products, and reducing the rework rate and defective rate caused by impurity contamination.

[0032] In actual application, a plurality of the first cleaning roller 302 and the second cleaning roller 304 may be provided to ensure a cleaning effect.

[0033] like Figure 1 As shown, in a preferred embodiment, the second connecting frame 308 is provided at both ends of the second cleaning roller 304 of the second spindle 303, the third spindle 305 is provided on the second connecting frame 308, the third cleaning roller 306 is sleeved on the third spindle 305, and the second connecting frame 308 is provided with a clamping mechanism 4, which is used to adjust the distance between the third cleaning roller 306 and the second cleaning roller 304.

[0034] Specifically, the clamping mechanism 4 includes a waist-shaped hole 401 arranged on the second connecting frame 308, and both ends of the third spindle 305 pass through the waist-shaped hole 401. The connecting frame is threadedly connected with an adjusting screw 402 at one end of the waist-shaped hole 401, and the screwed-in end of the adjusting screw 402 abuts against the third spindle 305.

[0035] During the cleaning process of the cover tape 801, when it is necessary to adjust the spacing between the second cleaning roller 304 and the newly added third cleaning roller 306 to adapt to the cover tape 801 of different thickness or characteristics, the operator will first loosen the adjustment screw 402 set at one end of the waist-shaped hole 401 of the second connecting frame 308. As the adjustment screw 402 is loosened, the original abutting force on the third spindle 305 is reduced, so that the third spindle 305 can move along its length direction in the waist-shaped hole 401, driving the third cleaning roller 306 to adjust its position inward or outward accordingly, thereby changing the spacing between the third cleaning roller 306 and the second cleaning roller 304. After the adjustment is completed, the operator tightens the adjustment screw 402 again, and fixes the third cleaning roller 306 at the new position through the abutment of the screw-in end with the third spindle 305, so that the third cleaning roller 306 and the second cleaning roller 304 work together at an appropriate spacing to perform adaptive cleaning on the cover tape 801.

[0036] In this embodiment, by setting up a third cleaning roller 306 and equipping it with a clamping mechanism 4 with adjustable spacing, the operator can quickly adjust the position of the third cleaning roller 306, so as to clean the cover tape 801 with different thicknesses, materials or surface characteristics. This can not only optimize the cleaning effect and prevent incomplete cleaning or damage to the cover tape 801 due to improper cleaning roller spacing, but also improve the versatility of the equipment.

[0037] like Figure 1 As shown, in a preferred embodiment, the first cleaning roller 302, the second cleaning roller 304 and the third cleaning roller 306 are movably mounted on the first spindle 301, the second spindle 303 and the third spindle 305, respectively; bearings are provided at both ends of the first cleaning roller 302, the second cleaning roller 304 and the third cleaning roller 306; the first cleaning roller 302, the second cleaning roller 304 and the third cleaning roller 306 are rotatably connected to the first spindle 301, the second spindle 303 and the third spindle 305 through bearings, respectively; positioning sleeves are provided at both ends of the first cleaning roller 302; the positioning sleeves and the second connecting frame 308 are both provided with fixing screws, the fixing screws are abutted against the spindle, and the lengths of the first cleaning roller 302, the second cleaning roller 304 and the third cleaning roller 306 are at least twice the width of the cover tape 801.

[0038] In actual operation, when the first cleaning roller 302, the second cleaning roller 304 or the third cleaning roller 306 has a reduced adhesion to the working surface due to long-term use, affecting the cleaning effect, the operator will first loosen the set screw at one end of each cleaning roller, remove the cleaning roller from the mandrel, turn it over and reinstall it on the mandrel, or change its current working surface by moving the cleaning roller on the mandrel. After completing these operations, tighten the set screw again to ensure that the cleaning roller is firmly installed on the mandrel.

[0039] In this embodiment, the first cleaning roller 302, the second cleaning roller 304 and the third cleaning roller 306 can freely change the installation direction or adjust the axial position on the mandrel, thereby improving the utilization rate and service life of the cleaning rollers, reducing the replacement frequency of the cleaning rollers, reducing maintenance costs, and reducing downtime, so that the equipment can continue to maintain efficient cleaning performance. In addition, since the length of the cleaning roller is designed to be at least twice the width of the cover tape 801, it is ensured that even after adjusting the installation direction or axial position, the entire width of the cover tape 801 can be fully covered to ensure the cleaning effect.

[0040] In a preferred embodiment, the first cleaning roller 302, the second cleaning roller 304 and the third cleaning roller 306 are silicone rollers. Silicone has good flexibility and elasticity, can closely fit the surface of the cover tape 801, and is sticky, effectively removes attached impurities, and reduces wear on the cover tape 801. After the use cycle is reached, the surface can be cleaned to restore its stickiness.

[0041] like Figure 1 and Figure 3 As shown, in a preferred embodiment, a tensioning mechanism 5 is provided between the frame 1 and the second spindle 303 , and the tensioning mechanism 5 is used to adjust the tension of the cover tape 801 .

[0042] The tensioning mechanism 5 includes a deformable member, a first end of which is connected to the frame 1, a second end of which is connected to the second spindle 303, and a constant force member is provided on the deformable member for providing a constant force to the first and second ends of the deformable member.

[0043] When it is necessary to adjust the tension of the cover tape 801 to meet different production requirements or solve the problem of looseness of the cover tape 801 during operation, adaptive adjustment is performed through the tensioning mechanism 5. As the source of force, the constant force member can provide a constant force to the first end and the second end of the deformable member, and the deformable member will deform accordingly. This deformation is converted into a thrust or pull on the second spindle 303 through the connection point between the deformable member and the second spindle 303. Since the frame 1 is fixedly connected to the first end of the deformable member, the deformation of the deformable member will drive the first connecting member to swing on the first spindle 301, adjust the position of the second cleaning roller 304, and thus adjust the tape path, so that the tension of the cover tape 801 is adjusted, ensuring the stability and reliability of the cover tape 801 during transmission.

[0044] like Figure 3 As shown, in a preferred embodiment, the deformation member and the constant force member are an integrated structure.

[0045] Specifically, the deformation member and the constant force member are elastic members, such as coil springs.

[0046] The integrated structure in this embodiment makes the overall structure more compact and easy to install and maintain. The coil spring, as an elastic member, can provide a constant force and automatically adjust its deformation degree as the tension of the cover tape 801 changes. This automatic adjustment mechanism ensures the accuracy and efficiency of the adjustment, reduces manual intervention, and reduces the complexity of operation.

[0047] In a preferred embodiment, the deformation member and the constant force member are split structures.

[0048] The deformation member is a telescopic rod, and the constant force member is a spring. Specifically, the deformation member and the constant force member are spring dynamometers, and the tension change can be intuitively seen.

[0049] The spring dynamometer integrates the functions of deformation and constant force. On the other hand, through its intuitive reading function, the operator can instantly and accurately grasp the tension state of the cover tape 801, improve the accuracy and efficiency of adjustment, and reduce production problems caused by improper tension. At the same time, the split structure allows the deformation part and the constant force part to each perform independent functions, which is convenient for maintenance and replacement, and improves the reliability and service life of the equipment.

[0050] In practical applications, the constant force member may be a pneumatic constant force member or a hydraulic constant force member, and a pressure sensor may be provided to detect the tension in real time.

[0051] In a preferred embodiment, a tension adjusting member is provided on the tensioning mechanism 5, and the tension adjusting member is used to adjust the force of the constant force member. Specifically, the movable end of the spring is connected to an adjusting nut threadedly connected to the telescopic rod, and the initial elongation of the spring is adjusted by turning the adjusting nut.

[0052] In the above technical design, the tension adjustment member added to the tensioning mechanism 5, especially the adjustment nut threadedly connected to the telescopic rod through the spring movable end, greatly enhances the flexibility and adjustability of the tensioning mechanism 5. This innovation allows the operator to accurately control the initial elongation of the spring by simply turning the adjustment nut, thereby achieving fine-tuning of the output force of the constant force member. This intuitive adjustment method not only improves production efficiency, but also ensures that the optimal tension state can be maintained under different working conditions, effectively avoiding production problems caused by improper tension. In addition, the design also simplifies the complexity of tension adjustment, reduces the requirements for operator skills, and makes the adjustment and maintenance of the tensioning mechanism 5 more convenient and efficient.

[0053] In a preferred embodiment, the deformable member is a traction rope, and the constant force member is a weight hung on the traction rope. The tension is adjusted by increasing or decreasing the weight.

[0054] In this embodiment, since the gravity provided by the weights is constant, it is possible to ensure that the tension remains relatively stable during long-term operation, reducing production problems caused by tension fluctuations. In addition, by simply increasing or decreasing the number of weights, the tension can be adjusted intuitively and accurately, and the adjustment method is simple.

[0055] like Figure 1 and Figure 4 As shown, in a preferred embodiment, a fourth spindle 201 is provided on the frame 1, and the unwinding disk 2 includes a support member 202 sleeved on the fourth spindle 201, the outer diameter of the support member 202 is equivalent to the inner diameter of the cover tape roll 8 core, and a first baffle 203 and a second baffle 204 are respectively provided on both sides of the support member 202.

[0056] A fixing ring 205 is disposed on the first side of the first baffle 203 , and a clamping mechanism 6 is disposed on the second side of the second baffle 204 , which pushes the second baffle 204 toward the first baffle 203 , thereby clamping the cover tape roll 8 and allowing the first baffle 203 and the second baffle 204 to guide the cover tape 801 .

[0057] The clamping mechanism 6 includes a movable ring 601 disposed on the second side of the second baffle 204, an elastic stopper 602 disposed on the second side of the movable ring 601, a stopper sleeve 603 disposed on the second end of the elastic stopper 602, and a nut 604 threadedly connected to the fourth spindle 201 disposed on the second side of the stopper sleeve 603. Specifically, the elastic stopper 602 is a coil spring.

[0058] In this embodiment, the fourth spindle 201 is provided as a supporting core to ensure the stable rotation of the unwinding disk 2. The outer diameter of the support member 202 is precisely matched with the inner diameter of the core of the cover tape roll 8, which is not only convenient for installation, but also effectively prevents the cover tape roll 8 from shaking during rotation. The first baffle 203 and the second baffle 204 clamp the cover tape roll 8 through the clamping mechanism 6, and guide the cover tape 801 during unwinding. In addition, by rotating the nut 604, the elastic limit member 602 can be compressed to adjust the clamping force, which not only ensures the reliability of clamping, but also avoids damage to the cover tape 801 caused by over-tightening. In addition, the elastic limit member 602 is positioned by the limit sleeve 603, which further enhances the stability of the entire clamping system.

[0059] like Figure 1 As shown, in a preferred embodiment, the frame 1 is provided with a second cleaning assembly 7 on one side of the unwinding reel 2 , a gap is provided between the second cleaning assembly 7 and the unwinding reel 2 , and the second cleaning assembly 7 is used for adsorbing and cleaning the cover tape 801 .

[0060] The second cleaning component 7 is an ion fan.

[0061] The ion fan can effectively absorb tiny dust on the surface of the cover tape 801 and remove static electricity by generating charged ions, thereby improving the cleanliness of the cover tape 801. The setting of maintaining an appropriate gap with the unwinding disk 2 ensures that the ion fan can fully act on the cover tape 801 without hindering its transmission. In addition, as a non-contact cleaning method, the ion fan avoids the wear and scratches that may be caused by traditional mechanical cleaning, and protects the integrity of the cover tape 801.

[0062] A baling machine described in an embodiment of the utility model comprises the above-mentioned release mechanism for cleaning the cover tape.

[0063] In this embodiment, by using the above-mentioned release mechanism for cleaning the cover tape, the cleanliness of the surface of the cover tape 801 can be ensured, and the firmness and sealing of the workpiece packaging can be ensured. On the other hand, the clean surface of the cover tape 801 reduces the possible contamination of the workpiece during packaging, improves the appearance of the product, protects the quality of the workpiece, and reduces the product defect rate.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
