Description

Technical Field

[0001] This utility model relates to the field of cap tape slitting machine technology, and in particular to a cap tape slitting machine. Background Technology

[0002] In the field of surface mount technology (SMT) for electronic components, cover tape, as a core component of carrier tape packaging, is mainly used to cover electronic components within the carrier tape slot, preventing them from falling off, oxidizing, or being damaged during transportation, storage, and placement due to vibration, static electricity, or environmental contaminants. In traditional cover tape production, wide raw materials need to be slit according to customer requirements. Early slitting processes relied on manual operation or semi-automated equipment, resulting in low cutting accuracy, insufficient efficiency, high material loss rates, and edge burrs or wavy deformation. These issues directly affect the heat-sealing quality of the cover tape and carrier tape, leading to positioning deviations or tape jamming when the SMT pick-up machine picks up components, thus reducing production line yield.

[0003] A search revealed a Chinese patent for a matte heat-sealing film cover slitting machine, publication number [redacted]. <cn220994545u>The slitting machine includes a slitting machine body, inside which is a moving cutting mechanism. The moving cutting mechanism includes a first motor, which is fixedly connected to the inner wall of the slitting machine body via a bracket. A sleeve is fitted with a rack, the lower end of which meshes with a gear. One end of the gear is fixedly connected to the output shaft of a second motor. The outer wall of the second motor is fixedly connected to the slitting machine body via a bracket. Through the cooperation of the slitting machine body, the moving cutting mechanism, and the cutter, the first motor drives the reciprocating screw to rotate, the gear drives the rack to move downward under the constraint of the sleeve, and the rack drives the cutter to move downward, pressing against the heat sealing strip. In this way, the cutter can perform cuts of any width, and can also slitting heat sealing strips of different thicknesses, reducing processing limitations.

[0004] The above solution drives the lateral displacement of the cutting mechanism through a single lead screw. Although the precision threaded pair of the lead screw can theoretically meet the slitting and positioning requirements, the radial clearance of the lead screw pair and the cantilevered force-bearing structure are prone to causing lateral displacement and vibration during high-speed continuous operation. Therefore, we propose a cover strip slitting machine. Utility Model Content

[0005] The purpose of this invention is to provide a cover strip slitting machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cover strip slitting machine includes a device base. From front to back, a first support plate group, a second support plate group, and a third support plate group are respectively provided on both sides of the top of the device base.

[0011] As a preferred embodiment of this utility model, the two ends of the mounting plate are fixedly connected to the slider.

[0012] As a preferred embodiment of this utility model, the lead screw transmission assembly includes a lead screw disposed between two second support plate groups on both sides, and auxiliary linear guides are fixedly connected between the two second support plate groups on both sides and located on the front and back sides of the lead screw. The lead screw is threadedly connected to a connecting seat, and a second drive motor is provided on the outer surface of one side of the second support plate group.

[0013] As a preferred embodiment of this utility model, the connecting seat is slidably connected to the auxiliary linear guide tube, the connecting seat is fixedly connected to the electric push rod, and the output end of the second drive motor is connected to the lead screw drive.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, by adding auxiliary linear guide tubes to the front and back of the lead screw drive assembly, a double guide constraint mechanism is formed with the lead screw, which forcibly restricts the non-axial degree of freedom of the cutting mechanism (including electric push rod and cutter) during lateral movement, and significantly suppresses lateral offset and vibration during high-speed slitting.

[0017] By using a hydraulic cylinder to drive the tensioning roller to lift and lower, combined with a chute and slider vertical guide structure, the tension of the cover belt is dynamically adjusted in real time to ensure that the material is always under constant tension during the slitting process, preventing tensile deformation caused by slack or excessive tightness, and reducing the hidden danger of poor heat sealing from the source.

[0027] Example

[0028] like Figure 1-4 As shown, this utility model provides a technical solution: a cover strip slitting machine, including a device base 1, the device base 1 provides overall support and stability, carries all functional modules, and ensures stable operation of the equipment; the top two sides of the device base 1 are respectively provided with a first support plate group 101, a second support plate group 102 and a third support plate group 103 from the front to the back.

[0029] The first support plate assembly 101 has a first transmission roller 2 on the upper front side and a second transmission roller 201 on the lower rear side. The first transmission roller 2 and the second transmission roller 201 form a cover belt conveying path. The former guides the material in, and the latter works with the tensioning assembly 4 to adjust the conveying tension. A fixed plate 3 with a hydraulic cylinder 301 spanning across is connected between the two support plates. The piston rod of the hydraulic cylinder 301 is connected to the lifting tensioning assembly 4. The hydraulic cylinder 301 drives the mounting plate 401 to rise and fall. The slider 4041 slides and guides the tensioning roller 403 to move vertically, thereby achieving dynamic tension adjustment and preventing the cover belt from being too loose or too tight.

[0030] The tensioning assembly 4 includes a mounting plate 401, with vertical plates 402 fixedly connected to both ends of the bottom of the mounting plate 401. A tensioning roller 403 is provided between the two vertical plates 402. Sliding grooves 404 are symmetrically opened on the inner side of the first support plate group 101 on both sides. A slider 4041 is slidably connected in the sliding groove 404. The two ends of the mounting plate 401 are fixedly connected to the slider 4041. The sliding groove 404 guides the vertical movement trajectory of the tensioning roller 403 to avoid deviation. The hydraulic cylinder 301 responds to the control signal in real time to adjust the height of the tensioning roller 403 to ensure that the tension of the cover strip is constant during the slitting process and reduce material stretching deformation.

[0031] The second support plate group 102 is provided with a protective cover plate 5 covering the cutting area on the top. A cutting mechanism that can move laterally is provided between the second support plate groups 102. The mechanism includes an electric push rod 7 driven by a lead screw transmission assembly 6 and a cutter 701 located at its bottom end. The lead screw 601 is driven by the second drive motor 604 to drive the connecting seat 603 to move laterally and accurately. The electric push rod 7 controls the pressing depth of the cutter 701 to achieve continuous cutting and adapt to different cutting specifications.

[0032] Auxiliary linear guide 602 is fixedly connected between the second support plates on both sides and on the front and back of the lead screw 601. The lead screw 601 provides lateral movement power, and the auxiliary guide enhances the movement stability of the slider 4041.

[0033] The third support plate group 103 is provided with a winding mechanism. The winding mechanism includes a winding roller 8 rotatably connected between the third support plate groups 103. A first drive motor 801 is provided on the outer side of one of the third support plates and is drivenly connected to the winding roller 8. The first drive motor 801 drives the winding roller 8 to rotate at a uniform speed and winds up the finished product in sync with the slitting speed, so as to keep the production line running continuously.

[0034] An integrated controller 9 is provided on the outside of the first support plate group 101. The integrated controller 9 is electrically connected to the hydraulic cylinder 301, the first drive motor 801, the second drive motor 604 and the electric push rod 7 through multiple control lines to form a closed-loop motion control system. By centrally controlling the lifting of the hydraulic cylinder 301, the speed of the drive motor, the cutting movement and the timing of the blade, the closed-loop feedback coordinates the actions of each component to ensure tension stability and cutting accuracy.

[0035] The working process of this utility model is as follows: When using a cap tape slitting machine, the cap tape material is guided into the equipment by the first transmission roller 2. The first transmission roller 2 and the second transmission roller 201 work together to form a basic conveying path. At this time, the hydraulic cylinder 301 drives the tensioning assembly 4 to rise and fall according to the control unit command. The mounting plate 401 slides vertically along the slide groove 404 through the slider 4041, driving the tensioning roller 403 to dynamically adjust the tension of the cap tape, avoiding the material from being stretched and deformed due to slack or too tight, and ensuring constant tension during the slitting process. Subsequently, the cap tape enters the cutting area, the protective cover plate 5 ensures operational safety, the second drive motor 604 drives the lead screw transmission assembly 6 to move the cutting mechanism laterally, and the connecting seat 603 precisely adjusts the position of the cutter 701 under the stable guidance of the auxiliary linear guide 602. At the same time, the electric push rod 7 controls the pressing depth of the cutter 701. The system continuously slits tapes of different widths. The slit tapes are then pulled at a constant speed by the winding mechanism of the third support plate group 103. The first drive motor 801 drives the winding roller 8 to rotate synchronously with the slit speed, maintaining continuous operation of the production line. The integrated controller 9 coordinates the lifting amplitude of the hydraulic cylinder 301, the speed of the drive motor, the displacement of the cutting mechanism, and the cutting sequence in real time through closed-loop feedback via the integrated control unit, so that tension adjustment, slit accuracy, and winding efficiency are dynamically balanced. The structure of the groove 404 and the slider 4041 ensures the accuracy of the vertical movement trajectory of the tension roller 403, avoiding offset loss. The combination of the lead screw 601 and the auxiliary guide improves the stability of the lateral movement during cutting. The closed-loop control system centrally manages the actions of each module, taking into account both tension stability and slit quality. The overall structure achieves efficient and low-loss automated slit operation through functional linkage.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
