Description

Technical Field

[0001] The utility model relates to the technical field of carrier tape molding equipment, in particular to a carrier tape heating device. Background Art

[0002] A carrier tape refers to a strip product used in the field of electronic packaging. It has a specific thickness and has holes (also called pockets) for holding electronic components and positioning holes for indexing and positioning equidistantly distributed along its length. In the production and processing of the carrier tape, in order to improve the processability of the material, enhance the bonding effect, promote chemical reactions and ensure product quality, the carrier tape needs to be heated. In the current prior art, the automatic heating device usually uses a driving component to push the heating component to press the carrier tape, thereby heating a specific area of ​​the carrier tape. The heating component can be guided by the guide component when it moves, and can be buffered by the buffer component when it is pressed. However, the buffering force of the buffer component cannot be adjusted, and it cannot be adapted to the processing of a variety of products. Moreover, the buffering force does not cover the entire process, resulting in the various components of the device being easily damaged and deformed under long-term high temperature and unstable operation collisions, which not only reduces the service life of the device, but also reduces the quality of the carrier tape heating, and also makes the carrier tape relatively unstable when heated. Utility Model Content

[0003] The purpose of the utility model is to provide a carrier heating device, aiming to solve the technical problems existing in the prior art, such as the buffer force cannot be adjusted, the device is not highly applicable, the buffer force covers the heating process to a low extent, and the device is prone to wear and even deformation of various components under long-term high temperature and unstable operation collision, resulting in relatively unstable heating of the carrier and reduced service life, which in turn leads to poor heating quality of the carrier.

[0004] In order to solve the above technical problems, the utility model provides a carrier heating device, including: a mounting support, on which a driving assembly, and an upper heating assembly and a lower heating assembly relatively arranged, the driving assembly is used to drive the upper heating assembly to approach or move away from the lower heating assembly; a guide assembly, including a guide shaft and a movable seat, the movable seat is slidably clamped on the guide shaft, and the upper heating assembly is connected to the output end of the driving assembly through the movable seat; a buffer assembly, including an upper elastic member, a lower elastic member and an adjusting member, the upper elastic member and the lower elastic member are both sleeved on the guide shaft and are respectively located on the upper and lower sides of the movable seat, one end of the upper elastic member is fixedly connected to the mounting support, and the other end is connected to the adjusting member, and the adjusting member is connected to the movable seat and is used to adjust the initial telescopic length of the upper elastic member.

[0005] The upper heating assembly and the lower heating assembly are symmetrically arranged, and their heating surfaces are opposite to each other, so that both sides of the carrier tape can be heated at the same time, effectively improving the heating uniformity and heating efficiency of the carrier tape; the guide assembly and the drive assembly on the mounting support can accurately control the distance between the upper heating assembly and the lower heating assembly, thereby ensuring that the carrier tape can be stably heated during the heating process, and can provide a smooth and stable moving path for the upper heating assembly, so that the upper heating assembly can stably and accurately press the carrier tape, and reduce the forces in other directions on the carrier tape to a certain extent, preventing the carrier tape from being deformed due to the force, and reducing the quality of the carrier tape processing;

[0006] The buffer component, on the one hand, can move the adjustment part according to actual needs to change the preload force of the elastic part, and then adjust the pressure between the upper heating component and the lower heating component to maintain the best heating effect when processing materials of different thicknesses or different materials, effectively improving the applicability of the device; on the other hand, the upper elastic part and the lower elastic part at both ends of the guide shaft can absorb most of the impact force between the upper heating component and the lower heating component, and provide buffering force during the entire heating process, thereby greatly reducing the wear and collision deformation of various parts of the device, and can effectively extend the service life of the device.

[0007] Preferably, the adjusting member includes a connecting plate and at least one adjusting rod, the connecting plate is movably clamped on the guide shaft and fixedly connected to the upper elastic member, and the adjusting rod is rotatably connected to the connecting plate and the movable seat for adjusting the distance between the connecting plate and the movable seat.

[0008] The connecting plate can be movably clamped on one or more guide shafts and fixedly connected with the corresponding one or more elastic parts, which can improve the flexibility of the design and thus improve the expandability of the device. When connecting multiple elastic parts, these elastic parts can also be adjusted at the same time to improve the adjustment efficiency; the threaded connection can make the connection more stable and tight, which is conducive to improving the reliability of the connection between the adjustment part and the moving seat, so that they remain stable during the operation of the device. On the other hand, when any parts need to be replaced, they can be quickly disassembled at any time, which is conducive to improving the loading and unloading efficiency of the device and facilitating subsequent maintenance;

[0009] Preferably, the adjusting rod is provided with an adjusting knob and a screw, one end of the screw passes through the connecting plate and the movable seat and is threadedly connected to the movable seat, and the other end is connected to the adjusting knob, and the adjusting knob abuts against the connecting plate.

[0010] The screw rod passes through the connecting plate and is connected with the threaded connection between the moving seat. On the one hand, the connection stability and reliability between the screw rod and the moving seat can be improved. On the other hand, the position of the connecting plate relative to the moving seat can be adjusted more accurately by rotating the adjusting knob to adjust the telescopic length of the elastic member. In addition, when there is no locking mechanism, the current position state of the screw rod can be maintained. The adjusting knob can simplify the operation process of adjusting the telescopic length of the elastic member, and can also prevent the screw rod from being excessively screwed in or out, causing it to get stuck or detach from the connecting plate and the moving seat.

[0011] Preferably, the movable seat is provided with a plurality of sleeves, and the plurality of sleeves are respectively sleeved on the plurality of guide shafts and extend toward the direction of the lower heating assembly.

[0012] On the one hand, multiple sleeves can strengthen the structural rigidity of the moving seat, thereby improving the stability of the moving seat during operation. On the other hand, when there are no sleeves, the multiple elastic parts close to the lower heating assembly require a longer length to ensure that the moving seat can compress these elastic parts when moving to increase the buffering force, which is not conducive to cost savings. Therefore, multiple sleeves are equivalent to shortening the distance between the moving seat and these elastic parts, which can reduce the travel of the moving seat and the production and processing costs.

[0013] Preferably, the guide shafts are multiple and spaced apart, and the upper elastic member, the lower elastic member, the sleeve, and the adjusting member are multiple and matched with the guide shafts.

[0014] Multiple guide shafts arranged at intervals can improve the structural stability of the mounting support, while enhancing the smoothness and stability of the moving path of the upper heating component, further reducing the misaligned heating or pressing deformation caused by path deviation, so that the upper heating component can stably and accurately press the carrier, thereby improving the quality of carrier heating; the upper elastic member and the lower elastic member are multiple and match the guide shaft, and the guide assembly is subjected to the increased tension of the upper elastic member and the thrust of the lower elastic member, which can further improve the buffering force of the buffer assembly on the guide assembly; multiple sleeves matching the guide shaft are respectively sleeved on the multiple guide shafts, which can strengthen the structure of the moving seat, so that the moving seat is subjected to uniform force during movement, and reduce deformation of parts caused by stress concentration; multiple adjustment members can further enhance the stability and reliability of the connection between the upper elastic member and the moving seat, and can also prevent the length of the upper elastic member from changing due to interference after the upper elastic member completes the adjustment of the telescopic length, and can also regulate each upper elastic member on each guide shaft.

[0015] Preferably, the upper heating assembly and the lower heating assembly both include a heating mold and an iron heating plate, the heating mold and the heating plate are detachably connected, the heating surfaces of the two heating molds are opposite, and a plurality of heating tubes arranged at intervals are provided in the heating plate.

[0016] The iron heating plate has a good temperature locking effect, can better provide stable heating to the heating mold, and has good wear resistance and impact resistance. It is not easy to deform under long-term high temperature and unstable operation collision, which effectively improves the service life of the heating plate; the threaded connection between the heating plate and the heating mold means that different types of carriers can be replaced for processing, which effectively improves the scalability of the device, and the thermal expansion coefficients of the heating plate and components such as bolts are similar, which will not cause the problem of difficult disassembly between the heating mold and the heating plate, and facilitate subsequent maintenance; compared with copper and aluminum, the cost of iron heating plates is lower; in addition, the thermal expansion coefficients between the iron heating plate and the thread are similar, and it can also be smoothly disassembled under long-term high temperature and collision environment, which is convenient for timely maintenance.

[0017] Multiple heating tubes can make the heating plate heat up faster, reduce the time required to reach the specified temperature, and improve the production and processing efficiency of the carrier; multiple heating tubes arranged at intervals can keep the heating temperature of each part of the heating plate relatively uniform, further make the heating mold heated evenly, and improve the heating quality of the carrier.

[0018] Preferably, the upper heating assembly and the lower heating assembly are further provided with a heat insulation plate, and the heat insulation plate is located on a side of the heating plate away from the heating mold.

[0019] The heat insulation board can prevent the heat generated by the heating plate from diffusing to the surrounding environment, especially to the mounting support and the guide drive assembly, effectively reducing the heat transfer between the heating assembly and other components, which can reduce the thermal stress of the entire system and help extend the service life of all related components; in addition, the heat insulation board reduces heat loss, helps to improve the energy utilization of the heating assembly, thereby improving the heating efficiency.

[0020] Preferably, the upper heating assembly and the lower heating assembly are further provided with a cooling plate, and the cooling plate is located on a side of the heat insulation plate away from the heating plate.

[0021] The cooling plate can quickly dissipate the heat generated by the heating component that is not completely isolated by the insulation plate, preventing the insulation plate from accumulating heat and overheating, which may affect the components connected to it, especially the mounting bracket and drive assembly, helping to extend the service life of all related components; in addition, the combined use of the insulation plate and the cooling plate can effectively control the operating temperature of the heating component, ensuring that the temperature is stable within the required range.

[0022] Preferably, any one of the heating plates is made of SKD11.

[0023] SKD11 is a cold die steel with high hardness, strength, and heat resistance balance. Therefore, the heating plate made of SKD11 has strong wear resistance and deformation resistance under high temperature conditions. Under long-term high temperature and collision, it can maintain its structural integrity and extend its service life; SKD11 has low thermal conductivity and good temperature locking performance, which can effectively improve the heating capacity of the mold; in addition, since the thermal expansion coefficient of parts such as bolts used in threaded connections is generally similar to that of SKD11, under long-term high temperature conditions, there will not be much change in the fastening force between them, which is conducive to subsequent maintenance.

[0024] Preferably, it also includes a temperature control component, which includes a temperature sensor and a temperature controller. The upper heating component and the lower heating component are both provided with temperature sensors, and the temperature controller is electrically connected to the temperature sensor and the plurality of heating tubes.

[0025] The temperature sensor is responsible for monitoring the temperature of the heating plate and feeding back to the temperature controller. The temperature controller then adjusts the temperature of multiple heating tubes according to the control program, thereby controlling the temperature of the heating plate to ensure the consistency and repeatability of the temperature when the carrier is heated, thereby improving the quality and performance of the carrier.

[0026] Compared with the prior art, the beneficial effects of the utility model are:

[0027] The drive component and the guide component are used to provide a stable movement path for the process of pressing the carrier tape between the two heating components, which can effectively improve the accuracy and stability of the carrier tape heating, and to a certain extent reduce the impact force that may be generated between the two heating components, thereby reducing the wear and deformation of the heating plate. The buffer component is used to assist and buffer the pressing collision and reset during the heating process, which improves the impact resistance and deformation resistance of each component in the device, making it less likely to wear and deform under long-term high temperature and operation collision, and can effectively increase the service life of the heating plate. In addition, the adjustment part can be moved according to actual needs to change the preload force of the elastic part, and then adjust the pressure between the upper heating component and the lower heating component to maintain the best heating effect when processing materials of different thicknesses or different materials, effectively improving the applicability of this device to different types of carrier tapes.

In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0035] In this embodiment, please refer to Figure 1 and Figure 2 As shown, the present invention provides a carrier heating device, which includes a mounting support 10, on which is provided a driving component 20, a guide component 30, and an upper heating component 50 and a lower heating component 60 that are relatively arranged, and the heating surfaces 511 on the upper heating component 50 and the lower heating component 60 that are responsible for heating the carrier 70 are relatively.

[0036] The driving assembly 20 uses a cylinder 21 and a piston rod 22. The cylinder 21 is arranged on the mounting support 10. The output end of the cylinder 21 is connected to the piston rod 22. The piston rod 22 is fixedly connected to the moving seat 32.

[0037] The guide assembly 30 includes a guide shaft 31 and a movable seat 32. The movable seat 32 is slidably mounted on the guide shaft 31. The upper heating assembly 50 is connected to the output end of the driving assembly 20 through the movable seat 32. The driving assembly 20 drives the upper heating assembly 50 to approach or move away from the lower heating assembly 60.

[0038] The buffer assembly 40 includes an upper elastic member 41, a lower elastic member 42 and an adjusting member 43. The upper elastic member 41 and the lower elastic member 42 are sleeved on the guide shaft 31 and are respectively located on the upper and lower sides of the movable seat 32. One end of the upper elastic member 41 is fixedly connected to the mounting support 10, and the other end is connected to the adjusting member 43. One end of the lower elastic member 42 is connected to the mounting support 10, and the other end extends toward the movable seat 32. The adjusting member 43 is connected to the movable seat 32 and is used to adjust the initial telescopic length of the upper elastic member 41 to adjust the preload force of the upper elastic member 41 and adapt to different types of products to be processed.

[0039] It can be understood that, in addition to the top and bottom, the mounting support 10 has openings on opposite sides of its circumference for the carrier tape 70 to enter and exit the mounting support 10; the guide shaft 31 connects the two opposite surfaces of the mounting support 10, and its axial direction is perpendicular to the two opposite surfaces. When the movable seat 32 moves along the guide shaft 31, a clear moving path can be provided for the upper heating component 50 to approach or move away from the lower heating component 60; in order to allow the upper elastic member 41 to be stretched by the adjusting member 43, the upper elastic member 41 and the connecting plate 431 are fixedly connected; the upper heating component 50 and The structure of the lower heating assembly 60 is the same; when the upper elastic member 41 is adjusted to a compressed state, it can provide pulling force and pushing force to the movable seat 32 to provide buffering force and assistance when the upper heating assembly 50 is pressed with the carrier tape 70 and reset; when the upper elastic member 41 is adjusted to a stretched state, the upper elastic member 41 provides pulling force to the movable seat 32, and provides buffering force when the upper heating assembly 50 is pressed with the carrier tape 70, and provides assistance when the movable seat 32 is reset; the lower elastic member 42 provides buffering force to the movable seat 32 when the carrier tape 70 is pressed, and provides assistance when the movable seat 32 is reset.

[0040] In addition, the upper elastic member 41 and the lower elastic member 42 may not be mounted on the guide shaft 31, but may be located at other positions on the mounting support 10, so as not to affect the operation of other components and to achieve the above functions; the driving component 20 and the guide shaft 31 may also be detachably connected to the mounting support 10.

[0041] In this embodiment, please refer to Figure 1 and Figure 2As shown, the adjusting member 43 includes a connecting plate 431 and at least one adjusting rod 432 . The connecting plate 431 is movably clamped on the guide shaft 31 and fixedly connected to the upper elastic member 41 . The adjusting rod 432 is rotatably connected to the connecting plate 431 and the movable seat 32 .

[0042] It can be understood that the connecting plate 431 is used to connect the upper elastic member 41 and the adjusting rod 432, and compress or stretch the upper elastic member 41, so its shape and structure may not be fixed, and may be a plate-like structure; the adjusting rod 432 passes through the connecting plate 431 and the movable seat 32, and is threadedly connected to the connecting plate 431 or the movable seat 32. When there are multiple adjusting rods 432, they are arranged at intervals to jointly adjust the initial telescopic length of the upper elastic member 41.

[0043] For details, please refer to Figure 2 As shown, the adjustment rod 432 includes an adjustment knob 4321 and a screw 4322 , one end of the screw 4322 passes through the connecting plate 431 and the movable seat 32 and is threadedly connected to the movable seat 32 , and the other end is connected to the adjustment knob 4321 , and the adjustment knob 4321 abuts against the connecting plate 431 .

[0044] It can be understood that the adjusting knob 4321 is provided with one side of the screw 4322 abutting the connecting plate 431; the end of the screw 4322 close to the adjusting knob 4321 may not be provided with threads, and is rotatably connected to the connecting plate 431; the adjusting knob 4321 and the screw 4322 are detachably connected.

[0045] In addition, one end of the screw rod 4322 can pass through the movable seat 32 and the connecting plate 431 and be threadedly connected to the connecting plate 431 , and the other end is connected to the adjusting knob 4321 , and the adjusting knob 4321 abuts against the movable seat 32 .

[0046] More specifically, please refer to Figure 1 As shown, the movable seat 32 is provided with a sleeve 321, and the sleeve 321 is sleeved on the guide shaft 31 and extends toward the direction of the lower heating assembly 60.

[0047] It can be understood that the sleeve 321 is slidably connected to the guide shaft 31. When the movable seat 32 moves a certain distance, the extended end of the sleeve 321 can completely abut the elastic member, and the movable seat 32 continues to move, so that the upper heating component 50 can compress the elastic member during the pressing process of the lower heating component 60.

[0048] In addition, a limiting portion may be provided at the extended end of the sleeve 321 to completely cover the abutting elastic member, but it cannot affect the pressing process of the upper heating component 50 and the lower heating component 60.

[0049] More specifically, please refer to Figure 1 and Figure 2As shown, the guide shafts 31 are multiple and spaced apart. Accordingly, the upper elastic member 41 , the lower elastic member 42 , the sleeve 321 , and the adjusting member 43 are multiple and matched with the guide shafts.

[0050] It can be understood that when there are multiple guide shafts 31, the upper elastic member 41, the lower elastic member 42, and the sleeve 321 sleeved on the guide shaft 31 are also multiple and match the guide shaft, and the multiple sleeves 321 are respectively slidably clamped on the multiple guide shafts 31; the matching between the adjustment member 432 and the guide shaft 31 is proportional to the number, and the adjustment member 432 can be less than or more than the guide shaft 31; in the description of the aforementioned buffer assembly 40, because there is only one guide shaft 31, a single upper elastic member 41 corresponds to a single adjustment member 43, so that the guide shaft 31 If there are multiple upper elastic members 41, the multiple upper elastic members 41 may correspond to a single or multiple adjusting members 43; when multiple upper elastic members 41 correspond to a single adjusting member 43, the connecting plate 431 is connected to the multiple upper elastic members 41 and slidably clamped on the multiple guide shafts 31, the adjusting rod 432 is located between the multiple guide shafts 31, and the single adjusting rod 432 can adjust the multiple upper elastic members 41; when multiple upper elastic members 41 correspond to multiple adjusting members 43, the multiple upper elastic members 41 are respectively connected to multiple connecting plates, and each adjusting rod 432 can adjust one or more upper elastic members 41.

[0051] In this embodiment, please refer to Figure 1 and Figure 2 As shown, the upper heating component 50 and the lower heating component 60 are both provided with a heating mold 51 and an iron heating plate 52. The heating mold 51 and the heating plate 52 are detachably connected. The heating surfaces 511 of the two heating molds 51 are opposite to each other. A plurality of heating tubes 521 arranged at intervals are also provided in the heating plate 52.

[0052] It can be understood that the heating mold 51 and the heating plate 52 are connected by bolts. The iron heating plate 52 is used as a heat source. Its deformation resistance and temperature locking performance are stronger than those of the aluminum and copper heating plates 52. Moreover, the thermal expansion coefficients of the bolts and the iron heating plate 52 are close. After a long period of high-temperature heating, the fastening force between the bolts and the heating plate 52 will not change much, and the heating mold 51 can be smoothly disassembled; the arrangement direction of the multiple heating tubes 521 is the length or width direction of the heating plate 52, and the multiple heating tubes 521 extend to the outside of the heating plate 52 along their arrangement direction.

[0053] In addition, the plurality of heating tubes 521 are arranged in one or more rows at intervals, and the arrangement direction can be perpendicular to the moving direction of the upper heating plate 52 and tilted at a certain angle; the extension ends of the plurality of heating tubes 521 can be combined into one.

[0054] Specifically, the upper heating assembly 50 and the lower heating assembly 60 are also connected with a heat insulation board 53 , specifically, the heating plate 52 is connected with the heat insulation board 53 , and the heat insulation board 53 is located on a side away from the heating mold 51 .

[0055] It can be understood that in the upper heating assembly 50, the insulation board 53 is connected to the heating plate 52 and the movable seat 32, and is located between the heating plate 52 and the movable seat 32; in the lower heating assembly 60, it is located between the heating plate 52 and the mounting support 10; the insulation board 53 can be made of flexible materials with good heat resistance such as ceramic fiber, silicone rubber, and flexible graphite; the insulation board 53 needs to be equal to or cover the heating plate 52 to improve its insulation effect.

[0056] In addition, the heat insulating plate 53 and the heating plate 52 may be fixedly connected or detachably connected; the heat insulating plate 53 may also only cover a portion of the heating plate 52 , such as the portion near the center of the heating plate 52 .

[0057] More specifically, the heat insulating plate 53 is connected to a cooling plate 54 , and the cooling plate 54 is located on a side of the heat insulating plate 53 away from the heating plate 52 .

[0058] It can be understood that in the upper heating assembly 50, the cooling plate 54 is located between the insulation plate 53 and the movable seat 32 to protect the movable seat 32, and in the lower heating assembly 60, the cooling plate 54 is located between the insulation plate 53 and the mounting support 10 to protect the mounting support 10; a plurality of water flow channels can be arranged inside the cooling plate 54 to realize the cooling function of the cooling plate 54 through circulating cooling; similar to the insulation plate 53, the shape of the cooling plate 54 needs to be equal to or cover the insulation plate 53 to improve its cooling effect.

[0059] In addition, the cooling plate 54 and the insulation plate 53 can be fixedly connected or detachably connected; the cooling plate 54 can also be cooled by air, phase change materials or other methods; the cooling plate 54 can also only cover part of the insulation plate 53, such as the part near the center of the insulation plate 53.

[0060] In addition, in one embodiment, the movable seat 32 and the cooling plate 54, the mounting support 10 and the cooling plate 54, the cooling plate 54 and the heat insulation plate 53, the heat insulation plate 53 and the heating plate 52, and the heating plate 52 and the heating mold 51 can all be connected by bolts, and the same bolts can be used for connection.

[0061] In the aforementioned embodiment, the heating plate 52 is made of SKD.

[0062] It can be understood that SKD is a cold mold steel with high hardness, strength, and heat resistance balance. Therefore, the heating plate 52 made of SKD has good wear resistance and deformation resistance under high temperature conditions, and can maintain the structural integrity of the heating plate 52 during the long-term high temperature and collision of the carrier 70 heating process.

[0063] In one embodiment, the upper heating component 50 and the lower heating component 60 are also connected to a temperature control component not shown in the figure. The temperature control component includes a temperature sensor and a temperature controller. The temperature sensor is arranged on the upper heating component 50 and the lower heating component 60, and the temperature controller is electrically connected to the temperature sensor and the plurality of heating tubes 521 to adjust the heating temperature of the upper heating component 50 and the lower heating component 60.

[0064] It can be understood that the temperature sensor used to detect the temperature of the upper heating component 50 and the lower heating component 60 is generally fixed on the heating plate 52. Adhesion or other fixing methods can be used to ensure that the sensor can accurately reflect the surface temperature of the heating plate 52. There is no restriction on the type of temperature sensor, and thermocouples or thermistors can be used. When the temperature of the heating plate 52 changes, the temperature sensor will continuously monitor the temperature of the heating plate 52 and transmit the monitored temperature signal to the temperature controller through the connecting line. The temperature controller adjusts the power output of the heating tube 521 through the program according to the received signal to maintain the temperature stability of the heating plate 52. In addition, the temperatures controlled by the two temperature control components are not necessarily the same and need to be adjusted according to actual conditions.

[0065] The specific application process of the utility model is as follows:

[0066] The adjusting rod 432 is rotated to move the connecting plate 431 along the plurality of guide shafts 31 to compress or stretch the upper elastic member 41 connected to the connecting plate 431, thereby adjusting the preload force of the upper elastic member 41 to adapt to different types of carrier tapes 70 that need to be processed. The device is turned on to preheat the upper heating component 50 and the lower heating component 60, and the temperature control component starts to operate. When the temperature sensor detects a specified temperature, the carrier tape 70 heating process starts.

[0067] The carrier tape 70 enters the interior of the mounting support 10 and stops between the upper heating assembly 50 and the lower heating assembly 60. The driving assembly 20 drives the movable seat 32 to move along the multiple guide shafts 31, and the upper heating assembly 50 also moves toward the lower heating assembly 60. At this time, the upper elastic member 41 connected to the connecting plate 431 is in a compressed state. The upper elastic member 41 first pushes the movable seat 32 downward through the adjusting member 43 to assist the driving assembly 20 to drive the movable seat 32 to move downward along the multiple guide shafts 31, thereby assisting the upper The heating component 50 moves toward the lower heating component 60; when it moves a certain distance but has not yet pressed the carrier tape 70, the upper elastic member 41 connected to the connecting plate 431 becomes stretched, and pulls the movable seat 32 upward through the adjusting member 43, and the lower elastic member 42 abuts against the movable seat 32 and is compressed by the sleeve 321 of the movable seat 32. The compressed state provides an upward thrust for the movable seat 32 to prevent the upper heating component 50 from moving toward the lower heating component 60 to press the carrier tape 70, thereby achieving a buffer before pressing the carrier tape 70.

[0068] After the heating of the carrier tape 70 is completed, the upper elastic member 41 connected to the connecting plate 431 is still in a stretched state, and the movable seat 32 is pulled upward through the adjusting member 43, and the lower elastic member 42 is in a compressed state abutting against the sleeve 321, and the compressed state provides an upward thrust for the movable seat 32, and the upper elastic member 41 and the lower elastic member 42 assist the upper heating assembly 50 to move away from the lower heating assembly 60 during the process of the driving assembly 20 driving the movable seat 32 to reset along the multiple guide shafts 31; after moving a certain distance, the upper elastic member 41 connected to the connecting plate 431 becomes a compressed state, and begins to apply a downward thrust to the movable seat 32 through the adjusting member 43, and the lower elastic member 42 disengages from the sleeve 321, thereby achieving a buffer for the movable seat 32 when the device is reset.

[0069] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
