Description

Technical Field

[0001] This utility model relates to the technical field of heat sealing devices, and in particular to a heat sealing device for a tape and reel machine. Background Technology

[0002] A tape and reel machine is a device used to place loose electronic components onto a carrier tape, primarily for the packaging and arrangement of electronic components. Tape and reel machines can be divided into two main categories: semi-automatic and fully automatic. Their working principle involves placing components into the carrier tape after processes such as detection, reversing, and testing, and then encapsulating the components using heat sealing or cold sealing methods.

[0003] Chinese utility model patent CN221624164U discloses a tape packaging device for testing a tape packaging machine, including a worktable. The top surface of the worktable has a carrier track, and a carrier tape is disposed inside the carrier track. A drive assembly is disposed on the bottom surface of the worktable. A main unit is fixedly installed on the top surface of the worktable. An upper tape take-up roller is rotatably mounted on the surface of the main unit. A first guide roller and a second guide roller are rotatably mounted on the surface of the main unit. An upper tape is wound on the surface of the upper tape take-up roller. A packaging assembly is disposed on the top surface of the worktable. The packaging assembly includes a second motor fixedly installed on the top surface of the worktable. A swing arm is fixedly installed at the output end of the second motor. A heater is fixedly installed on one side of the swing arm. A heating block is disposed on one side of the heater.

[0004] Regarding the aforementioned technologies, the inventors believe the following drawbacks exist: Carrier tapes typically have a carrier box for storing components. The carrier tape advances to the packaging position within the carrier tape track. In the aforementioned technologies, a second motor drives a swing arm to rotate within the packaging assembly, thereby causing a heating block on the heater to rotate. The heating block heats the sealing tape and then packages it onto the carrier tape. However, the heating block can only fully heat the sealing tape when its bottom is parallel to the horizontal plane. If the second motor operates too quickly, the heating block may over-rotate, and the impact force generated by the heating block may damage the carrier box at the bottom of the carrier tape. If the second motor operates too slowly, it affects the packaging efficiency of the carrier tape. Utility Model Content

[0005] To solve the above problems, this utility model provides a heat sealing device for a tape and reel machine.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a heat sealing device for a tape feeding machine, comprising a mounting platform and a mounting plate fixed to one side of the mounting platform, wherein the top of the mounting platform is provided with a feed groove for the carrier tape to pass through, and a plurality of carrier boxes communicating with the top of the carrier tape are evenly arranged at the bottom of the carrier tape, a driving component for driving the carrier tape forward is provided on the mounting platform, and a clearance groove communicating with the bottom of the feed groove is provided at the position corresponding to the mounting plate on the top of the mounting platform, an elastic buffer unit is provided in the clearance groove, and a downward pressure heat sealing mechanism is provided at the position corresponding to the clearance groove on the mounting plate.

[0007] By adopting the above technical solution, an elastic buffer unit is set in the slot. When the pressure-type heat sealing mechanism presses down the sealing tape and heats it, the sealing is completed when the sealing tape is pressed down to the top of the carrier tape. This changes the traditional method of sealing by rotating a motor to drive a heating block. With the cooperation of the elastic buffer unit, it is beneficial to improve the efficiency of heat sealing the carrier tape while ensuring the integrity of the carrier box.

[0008] Furthermore, the elastic buffer unit includes an elastic buffer disposed on the mounting platform near the bottom wall of the relief groove and a sliding plate that slides in cooperation with the inner wall of the relief groove. The bottom of the sliding plate is fixed to the upper end of the connecting rod of the elastic buffer.

[0009] By adopting the above technical solution, in the initial state, the top of the sliding plate abuts against the bottom of the carrier box. During the process of the downward heat sealing mechanism pressing down the sealing tape and heating it, the carrier tape as a whole may move slightly downward. The elastic buffer unit composed of the sliding plate and the elastic buffer plays a good buffering role, reducing the probability of the carrier box being squeezed and damaged.

[0010] Furthermore, the downward-pressing heat-sealing mechanism includes a downward-pressing component and a heat-sealing component; the downward-pressing component includes a horizontal plate fixed to the mounting plate, a starting cylinder fixed to the horizontal plate, a movable plate fixed to the lower end of the piston rod of the starting cylinder and located below the horizontal plate, a heat-sealing cylinder fixed to the bottom of the movable plate, and a clamping column fixed to the output end of the heat-sealing cylinder; the heat-sealing component includes a vertical slide rail fixed to the mounting plate, a sliding seat slidably engaged with the vertical slide rail, a heat-sealing block fixed to the bottom of the sliding seat, and a heat-sealing blade detachably connected to the bottom of the heat-sealing block; the bottom of the movable plate is connected to both sides of the sliding seat by tension springs, two tension springs are provided and symmetrically distributed, the lower end of the clamping column abuts against the sliding seat, and the side wall of the heat-sealing block is connected to an external heating system through a heat transfer pipe.

[0011] By adopting the above technical solution, during normal heat sealing operations, the operator only needs to activate the heat sealing cylinder to control the downward movement of the clamping column, causing the tension spring to extend. This causes the sliding seat, heat sealing block, and heat sealing blade to all move downwards, allowing the heated heat sealing blade to heat the sealing tape and complete the heat sealing operation. After a period of use, the heat sealing blade may require cleaning or maintenance. In this case, the operator needs to adjust the starting cylinder to move the movable plate, heat sealing cylinder, clamping column, sliding seat, heat sealing block, and heat sealing blade upwards. This increases the space between the heat sealing blade and the top of the mounting platform, allowing the operator to disassemble the heat sealing blade for cleaning or maintenance.

[0012] Furthermore, a guide rod is fixed to the bottom of the horizontal plate, and the guide rod passes through the movable plate and slides in cooperation with it.

[0013] By adopting the above technical solution, the stability of the movable plate during the lifting and lowering process is enhanced.

[0014] Furthermore, the side wall of the abutment column is provided with a plurality of cutting portions evenly distributed about the axis of the abutment column, and the number of the cutting portions is even.

[0015] By adopting the above technical solution, the cutting part is designed to facilitate the operator to rotate the clamping column with a wrench. Due to the setting of the tension spring, the positions of the sliding seat, heat sealing block and heat sealing knife can be adjusted, which makes it convenient for the operator to adjust the position of the heat sealing knife according to different carrier belts or heat sealing knife models.

[0016] Furthermore, the drive assembly includes a drive motor fixed on the mounting platform, a drive pinwheel fixed to the output end of the drive motor, a main synchronous pulley rotatably mounted on the housing of the drive motor, a driven column passing through and rotatably connected to the mounting platform, a driven synchronous pulley fixedly sleeved on the driven column, a synchronous belt for connecting the driven synchronous pulley and the main synchronous pulley, and a driven pinwheel fixedly sleeved on the driven column. The surface of both the drive pinwheel and the driven pinwheel are provided with multiple transmission pins, and the carrier belt is provided with transmission pin holes that cooperate with the transmission pins.

[0017] By adopting the above technical solution, after the drive motor works, it drives the active pin wheel to rotate. The transmission pin on the active pin wheel drives the carrier belt forward through the transmission pin hole. The carrier belt is driven by the transmission pin hole and drives the driven pin wheel to rotate. In this way, the driven pin, the driven pin wheel, the driven synchronous pulley and the synchronous belt all rotate, ensuring the stability of the carrier belt during its forward movement.

[0018] Furthermore, the mounting platform is provided with a limiting mechanism for limiting the top of the carrier belt. The limiting mechanism includes a first pressing component and a second pressing component. The first pressing component includes a swing rod rotatably mounted on the mounting platform, a pressure roller rotatably connected to one end of the swing rod away from its rotation axis, a connecting rod fixed to the side of the swing rod away from the pressure roller, and a clamping spring for connecting the connecting rod to the rotation axis of the swing rod. The wheel surface at the bottom of the pressure roller abuts against the top of the carrier belt.

[0019] By adopting the above technical solution, under the pressing action of the pressing spring, the wheel surface at the bottom of the pressure roller is pressed against the top of the carrier belt, which helps to ensure the stability of the carrier belt during forward movement and heat sealing.

[0020] Furthermore, the second clamping assembly includes a linear slide rail fixed to the mounting plate, a mounting base that slides with the linear slide rail, and a clamping block fixed to one side of the mounting base. The clamping block is positioned near the heat sealing knife, and the bottom of the clamping block abuts against the top of the carrier tape.

[0021] By adopting the above technical solution, the structure and transmission principle of the mounting base and the linear slide rail are both existing technologies and need not be described in detail here. The power mechanism of the linear slide rail can drive the mounting base to rise and fall, so that the bottom of the clamping block abuts against the top of the carrier belt, further enhancing the stability of the carrier belt during the heat sealing process.

[0022] Furthermore, a cutting assembly is provided on the side of the mounting platform away from its feed end. The cutting assembly includes a cutting cylinder fixed on the mounting platform and a cutting table fixed on the mounting platform and located above the cutting cylinder. The cutting table includes a fixing block fixed on the mounting platform and located below the carrier box, and an L-shaped block fixed on the top of the fixing block. The horizontal section of the L-shaped block is located near the top of the carrier belt. The cutting assembly also includes a cutting blade connected to the piston rod end of the cutting cylinder. A through hole is provided on the fixing block to slide with the cutting blade.

[0023] By adopting the above technical solution, the cutting cylinder drives the cutting blade to rise after it works, thereby cutting the heat-sealed carrier tape, so as to cut carrier tape with different numbers of carrier boxes according to customer needs. The cut carrier tape can be collected by collection bags.

[0024] Furthermore, the mounting plate is provided with a sealing tape feeding assembly, which includes a connecting plate fixed to the mounting plate, a feeding disc rotatably mounted on the connecting plate, an upper tensioning rod rotatably mounted on the mounting plate, a rotating column rotatably mounted on the mounting plate, a traction rod fixed to one end of the rotating column, a guide wheel rotatably mounted to the end of the traction rod, a guide column rotatably mounted on the mounting plate, and a lower tensioning rod rotatably mounted on the mounting plate.

[0025] By adopting the above technical solution, the sealing tape released from the feeding tray passes sequentially around the upper tensioning rod, guide wheel, guide column and lower tensioning rod, and then enters between the heat sealing knife and the carrier tape, so that the heat sealing knife heat seals the carrier tape onto the carrier tape.

[0026] In summary, this utility model has the following beneficial effects:

[0027] 1. This application can improve the efficiency of heat sealing the carrier tape while ensuring the integrity of the carrier box;

[0028] 2. In this application, when the elastic buffer is in the initial state, the top of the sliding plate abuts against the bottom of the carrier box. During the process of the downward heat sealing mechanism pressing down the sealing tape and heating it, the carrier tape as a whole may move slightly downward. The elastic buffer unit composed of the sliding plate and the elastic buffer plays a good buffering role and reduces the probability of the carrier box being squeezed and damaged.

[0029] 3. In this application, during normal heat sealing operations, the operator only needs to activate the heat sealing cylinder to control the downward movement of the clamping column, causing the tension spring to extend. This causes the sliding seat, heat sealing block, and heat sealing blade to all move downwards, allowing the heated heat sealing blade to heat the sealing tape and complete the heat sealing operation. After a period of use, the heat sealing blade may require cleaning or maintenance. In this case, the operator needs to adjust the starting cylinder to move the movable plate, heat sealing cylinder, clamping column, sliding seat, heat sealing block, and heat sealing blade upwards, increasing the space between the heat sealing blade and the top of the mounting platform. This allows the operator to disassemble the heat sealing blade for cleaning or maintenance. Attached Figure Description

[0037] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0038] like Figure 1-6 As shown in the figure, this application discloses a heat sealing device for a tape and reel machine, including a mounting platform 1 and a mounting plate 2 fixed to one side of the mounting platform 1. The top of the mounting platform 1 is provided with a feeding groove 11 for a carrier tape 3 (not shown in the figure) to pass through. The bottom of the carrier tape 3 is provided with a plurality of carrier boxes 31 that communicate with the top of the carrier tape 3. The mounting platform 1 is provided with a driving component 4 for driving the carrier tape 3 forward. The top of the mounting platform 1 is provided with a relief groove 12 that communicates with the bottom of the feeding groove 11 at the position corresponding to the mounting plate 2. An elastic buffer unit 5 is provided in the relief groove 12. The mounting plate 2 is provided with a downward heat sealing mechanism 6 at the position corresponding to the relief groove 12.

[0039] The recessed groove 12 is equipped with an elastic buffer unit 5. When the pressing heat sealing mechanism 6 presses down the sealing tape and heats it, the sealing is completed when the sealing tape is pressed down to the top of the carrier tape 3. This changes the traditional method of sealing by rotating a motor to drive a heating block. With the cooperation of the elastic buffer unit 5, it is beneficial to improve the efficiency of heat sealing the carrier tape 3 while ensuring the integrity of the carrier box 31.

[0040] The elastic buffer unit 5 includes an elastic buffer 51 disposed on the mounting platform 1 near the bottom wall of the relief groove 12, and a sliding plate 52 that slides in cooperation with the inner wall of the relief groove 12. The bottom of the sliding plate 52 is fixed to the upper end of the connecting rod of the elastic buffer 51. The elastic buffer 51 is taken from a conventional product in the prior art, such as the Festo DYSS-G8-3-4-Y1F-G2 model elastic buffer 51. Its operating principle does not need to be elaborated in detail here. The elastic buffer 51 shown in the figure is only a simple illustration.

[0041] In the initial state, the top of the sliding plate 52 abuts against the bottom of the carrier box 31. During the process of the downward heat sealing mechanism 6 pressing down the sealing tape and heating, the carrier tape 3 may move slightly downward. The elastic buffer unit 5 composed of the sliding plate 52 and the elastic buffer 51 plays a good buffering role, reducing the probability of the carrier box 31 being squeezed and damaged.

[0042] The pressure-type heat sealing mechanism 6 includes a pressure assembly 61 and a heat sealing assembly 62; the pressure assembly 61 includes a horizontal plate 611 fixed to the mounting plate 2, an actuating cylinder 612 fixed to the horizontal plate 611, a movable plate 613 fixed to the lower end of the piston rod of the actuating cylinder 612 and located below the horizontal plate 611, a heat sealing cylinder 614 fixed to the bottom of the movable plate 613, and a clamping post 615 fixed to the output end of the heat sealing cylinder 614; the heat sealing assembly 62 includes components fixed to the mounting plate 2. The system includes a vertical slide rail 621, a sliding seat 622 that slides with the vertical slide rail 621, a heat sealing block 623 fixed to the bottom of the sliding seat 622, and a heat sealing knife 624 that is detachably connected to the bottom of the heat sealing block 623. The bottom of the movable plate 613 is connected to both sides of the sliding seat 622 by tension springs 6131. ​​Two tension springs 6131 are provided and symmetrically distributed. The lower end of the pressing column 615 is pressed against the sliding seat 622. The side wall of the heat sealing block 623 is connected to an external heating system through a heat transfer pipe.

[0043] During normal heat sealing operations, the operator only needs to activate the heat sealing cylinder 614 to control the downward movement of the clamping column 615, causing the tension spring 6131 to extend. This causes the sliding seat 622, heat sealing block 623, and heat sealing blade 624 to all move downwards, allowing the heated heat sealing blade 624 to heat the sealing tape and complete the heat sealing operation on the carrier tape 3. After a period of use, the heat sealing blade 624 may require cleaning or maintenance. In this case, the operator needs to adjust the starting cylinder 612 to move the movable plate 613, heat sealing cylinder 614, clamping column 615, sliding seat 622, heat sealing block 623, and heat sealing blade 624 upwards. This increases the space between the heat sealing blade 624 and the top of the mounting platform 1, allowing the operator to disassemble and clean or maintain the heat sealing blade 624.

[0044] To enhance the stability of the movable plate 613 during the lifting process, a guide rod 6111 is fixed at the bottom of the horizontal plate 611. The guide rod 6111 passes through the movable plate 613 and slides in cooperation with it.

[0045] The side wall of the clamping post 615 is provided with multiple cutting parts 6151 evenly distributed about the axis of the clamping post 615, and the number of cutting parts 6151 is even. The cutting parts 6151 make it easy for the operator to rotate the clamping post 615 with a wrench. Due to the setting of the tension spring 6131, the positions of the sliding seat 622, the heat sealing block 623, and the heat sealing knife 624 can be adjusted, so that the operator can adjust the position of the heat sealing knife 624 according to different carrier belts 3 or the model of the heat sealing knife 624.

[0046] The drive assembly 4 includes a drive motor 41 fixed on the mounting platform 1, a drive pin wheel 42 fixed to the output end of the drive motor 41, a main synchronous pulley 43 rotatably mounted on the housing of the drive motor 41, a driven column 44 that passes through the mounting platform 1 and is rotatably connected to it, a driven synchronous pulley 45 fixedly sleeved on the driven column 44, a synchronous belt 46 for connecting the driven synchronous pulley 45 and the main synchronous pulley 43, and a driven pin wheel 47 fixedly sleeved on the driven column 44. Multiple transmission pins 48 are provided on the wheel surface of the drive pin wheel 42 and the wheel surface of the driven pin wheel 47. The carrier belt 3 is provided with transmission pin holes 32 that cooperate with the transmission pins 48.

[0047] After the drive motor 41 operates, it drives the active pin wheel 42 to rotate. The transmission pin column 48 on the active pin wheel 42 drives the carrier belt 3 forward through the transmission pin hole 32. The carrier belt 3 is transmitted through the transmission pin hole 32 and drives the driven pin wheel 47 to rotate, thereby making the driven pin column 44, the driven pin wheel 47, the driven synchronous pulley 45, and the synchronous belt 46 all rotate, ensuring the stability of the carrier belt 3 during its forward movement. In other embodiments, the drive motor 41 can be a dual-head motor, with the main synchronous pulley 43 fixed on one of the output shafts of the drive motor 41.

[0048] The mounting platform 1 is provided with a limiting mechanism 7 for limiting the top of the carrier belt 3. The limiting mechanism 7 includes a first pressing component 71 and a second pressing component 72. The first pressing component 71 includes a swing rod 711 rotatably mounted on the mounting platform 1, a pressure roller 712 rotatably connected to one end of the swing rod 711 away from its rotation axis, a connecting rod 713 fixed to the side of the swing rod 711 away from the pressure roller 712, and a clamping spring 714 for connecting the connecting rod 713 to the rotation axis of the swing rod 711. The wheel surface at the bottom of the pressure roller 712 abuts against the top of the carrier belt 3.

[0049] Under the pressure of the clamping spring 714, the bottom surface of the pressure roller 712 is pressed against the top of the carrier belt 3, which helps to ensure the stability of the carrier belt 3 during forward movement and heat sealing.

[0050] The second clamping assembly 72 includes a linear slide rail 721 fixed on the mounting plate 2, a mounting base 722 that slides with the linear slide rail 721, and a clamping block 723 fixed to one side of the mounting base 722. The clamping block 723 is located near the heat sealing knife 624, and the bottom of the clamping block 723 abuts against the top of the carrier belt 3.

[0051] The structure and transmission principle of the mounting base 722 and the linear slide rail 721 are both existing technologies and need not be described in detail here. The power mechanism of the linear slide rail 721 can drive the mounting base 722 to rise and fall, so that the bottom of the clamping block 723 abuts against the top of the carrier belt 3, further enhancing the stability of the carrier belt 3 during the heat sealing process.

[0052] A cutting assembly 8 is provided on the side of the mounting platform 1 away from its feed end. The cutting assembly 8 includes a cutting cylinder 81 fixed on the mounting platform 1 and a cutting table 82 fixed on the mounting platform 1 and located above the cutting cylinder 81. The cutting table 82 includes a fixing block 821 fixed on the mounting platform 1 and located below the carrier box 31 and an L-shaped block 822 fixed to the top of the fixing block 821. The horizontal section of the L-shaped block 822 is located near the top of the carrier belt 3. The cutting assembly 8 also includes a cutting blade 83 connected to the piston rod end of the cutting cylinder 81. A through hole 8211 is provided on the fixing block 821 to slide with the cutting blade 83.

[0053] After the cutting cylinder 81 is working, it drives the cutting blade 83 to rise, thereby cutting the heat-sealed carrier tape 3, so as to cut the carrier tape 3 containing different numbers of carrier boxes 31 (different numbers of carrier boxes 31 correspond to different numbers of component products) according to customer needs. The cut carrier tape 3 can be collected by a collection bag (not shown in the figure).

[0054] The mounting plate 2 is provided with a sealing tape feeding assembly 9, which includes a connecting plate 91 fixed on the mounting plate 2, a feeding disc 92 rotatably mounted on the connecting plate 91 (for clarity, only one side of the feeding disc 92 is shown in the figure), an upper tensioning rod 93 rotatably mounted on the mounting plate 2, a rotating column 94 rotatably mounted on the mounting plate 2, a traction rod 95 fixed to one end of the rotating column 94, a guide wheel 96 rotatably mounted to the end of the traction rod 95, a guide column 97 rotatably mounted on the mounting plate 2, and a lower tensioning rod 98 rotatably mounted on the mounting plate 2.

[0055] The sealing tape released from the feeding tray 92 passes sequentially around the upper tension rod 93, guide wheel 96, guide post 97 and lower tension rod 98, and then enters between the heat sealing knife 624 and the carrier tape 3, so that the heat sealing knife 624 heat seals the carrier tape 3 onto the carrier tape 3.

[0056] The working principle of the heat sealing device for a tape and reel machine in this embodiment is as follows: an elastic buffer unit 5 is provided in the relief groove 12. When the pressing heat sealing mechanism 6 presses down the sealing tape and heats it, the sealing is completed when the sealing tape is pressed down to the top of the carrier tape 3. This changes the traditional method of sealing by rotating a motor to drive a heating block. With the cooperation of the elastic buffer unit 5, it is beneficial to improve the efficiency of heat sealing the carrier tape 3 while ensuring the integrity of the carrier box 31.

[0057] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
