Description

Technical Field

[0001] This utility model belongs to the field of carrier belt hot pressing technology, and in particular relates to a carrier belt hot pressing packaging equipment. Background Technology

[0002] Small hardware components such as spring clips are frequently used in electronic products such as mobile phones and tablets. After these small hardware components are processed, they need to be cut and transported to the placement cavity of the carrier belt by a handling mechanism. While the existing carrier belt thermo-press packaging equipment drives the small hardware components forward, the cover tape is pressed onto the carrier belt. Then, the thermo-press mechanism heats and presses the cover tape onto the carrier belt, thereby encapsulating the small hardware components inside the carrier belt.

[0003] Existing carrier tape heat-sealing packaging equipment often uses a cylinder-based heat-sealing mechanism. This mechanism uses the extension and retraction of a cylinder's telescopic rod to move a heated pressure block up and down, thus achieving batch packaging of the carrier tape. For example, Chinese utility model patent CN213009041U discloses a carrier tape film heat-sealing device, including a mounting plate. A heat-sealing head is fixedly mounted on the front end of the mounting plate, and a movable pressure head is slidably disposed above the heat-sealing head. A pressure head cylinder is fixedly mounted above the movable pressure head, and the telescopic end of the pressure head cylinder is fixedly connected to the movable pressure head. A roller frame is located on the right side above the mounting plate, and a roller is rotatably mounted on the roller frame. The roller is detachably mounted on the roller frame, and a film is wound around the roller. A guide device is located on the front end of the mounting plate, and the film is fitted onto the guide device. This utility model is a carrier tape film heat-sealing device with a simple structure, high smoothness, and convenient roller replacement.

[0004] Furthermore, Chinese utility model patent CN212530196U discloses a carrier tape hot-press sealing device, comprising: a support platform with a mounting base; a base plate disposed on the support platform for positioning and conveying the carrier tape and cover tape; a pressure knife located above the base plate for sealing the carrier tape and cover tape together; a pressure stabilizing component disposed on the mounting base for providing a stable pressure to the pressure knife; a position fine-tuning component disposed on the pressure stabilizing component for fine-tuning the position of the pressure knife to align the blade of the pressure knife with the carrier tape; a temperature control component disposed on the position fine-tuning component for providing a constant temperature to the pressure knife; a sealing depth positioning component disposed on the support platform for adjusting the sealing depth of the pressure knife; and a control system electrically connected to the pressure stabilizing component, the temperature control component, and the sealing depth positioning component. The carrier tape hot-press sealing device of this application has the advantages of high automation, high sealing efficiency, and good sealing quality.

[0005] However, existing carrier tape heat-sealing packaging equipment has at least the following technical problems: 1. Since the guiding mechanism for the cover tape is mostly a fixed guide block, the tension of the cover tape will increase during the heat-sealing process of the heat-sealing mechanism. When it exceeds the cover tape's bearing capacity, it is easy to cause the cover tape to deform, the feeding to get stuck, etc., and thus it cannot effectively adhere to and heat-seale the carrier tape; 2. During the heat-sealing process of the carrier tape and the cover tape, since there is no buffering effect between the heat-sealing block and the cover tape and the carrier tape, the carrier tape is prone to heat melting and deformation during heat-sealing, requiring frequent rework, which greatly affects the production progress and product quality, and cannot meet the dual requirements of efficiency and quality for mass production.

[0006] To address at least one technical problem existing in the prior art, this application provides a carrier belt heat-pressing packaging device that realizes flexible material guiding of the cover belt and flexible heat pressing of the carrier belt.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A carrier belt hot-press packaging device includes a support plate, a feeding plate on the support plate for guiding the carrier belt, and a feeding mechanism on the support plate for driving the carrier belt forward.

[0010] Preferably, there are two connecting rods vertically connected by threads on the fixed plate, and the two ends of the two tension springs are respectively hung on the connecting rods and the pressing block.

[0011] Preferably, a pressure sleeve is fixedly sleeved on the telescopic rod of the pressing cylinder, and the lower end face of the pressure sleeve abuts against the pressure block.

[0012] Preferably, a top plate is fixedly connected to the vertical plate above the fixed plate, and an actuating cylinder is fixedly connected vertically downward on the top plate. The telescopic rod of the actuating cylinder can slide through the top plate and be connected to the fixed plate.

[0013] Preferably, a linear bearing sleeve is vertically embedded in the fixed plate, and a guide shaft is fixedly connected to the top plate, the guide shaft slidingly passing through the linear bearing sleeve.

[0014] Preferably, the guide plate has a waist-shaped adjustment through hole in the horizontal direction perpendicular to the conveyor belt, and the adjustment bolt passes through the adjustment through hole and is threaded into the sliding plate to fix the guide plate to the sliding plate.

[0015] Preferably, an avoidance groove is provided on the upper surface of the sliding plate, and an adjusting rod is rotatably embedded in the avoidance groove.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model, by setting a tension spring II, a sliding guide plate and an extension cross plate and a guide groove, not only guides the cover strip, but also ensures that the tension of the cover strip is always kept within a certain range by the stretching degree of the tension spring II, so as to avoid the cover strip being deformed due to excessive tension, which would lead to heat-pressing failure.

[0020] 2. This utility model uses a tension spring to buffer the hot press head during high-frequency hot pressing. In addition, by setting a buffer mechanism, the cover tape and carrier tape are further buffered during hot pressing, avoiding technical problems that are prone to occur during hot pressing and sealing, such as carrier tape heat melting and deformation, and the need for frequent rework. This speeds up the production process, improves product quality, and can meet the dual requirements of efficiency and quality for mass production. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0039] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example

[0040] See appendix Figure 1 , 2As shown in Figure 3, a carrier belt heat-sealing packaging device includes a horizontally arranged base plate 11. A support plate 12 is vertically fixed to the base plate 11 by bolts, and a feeding plate 13 is horizontally fixed to the upper part of the support plate 12 by bolts. The feeding plate 13 is used to guide the carrier belt 14. The feeding plate 13 has a long strip-shaped structure. A feeding groove 131 is formed on the upper end face of the feeding plate 13 along its length. The carrier belt 14 is slidably embedded in the feeding groove 131. The carrier belt 14 is of the prior art, with a plurality of feeding holes 141 evenly distributed along its length on one side. A product placement groove 142 is formed by a downward indentation on the upper end face of the carrier belt 14. To prevent the carrier belt 14 from detaching from the feeding groove 131 during conveying, pressure plates 15 are fixedly connected to the feeding plates 13 on both sides of the feeding groove 131 by bolts. Thus, the carrier belt 14 is conveyed forward within the feeding channel formed by the pressure plates 15 and the feeding groove 131. Furthermore, to facilitate the inspection of products within the carrier belt 14, multiple inspection slots 151 are formed along the length of the pressure plate 15. An inspection camera assembly 16 is positioned above one of these inspection slots 151. The camera in the inspection camera assembly 16 can inspect the products within the product placement groove 142 below the inspection slot 151 to detect the presence of material or product defects. This structure is existing technology; in other embodiments, the structural form may differ, as long as it achieves the guiding and feeding of the carrier belt 14.

[0041] Furthermore, for ease of description, the station where the carrier tape 14 is hot-pressed is designated as hot-press station 17. Hot-press station 17 is located behind the inspection camera assembly 16, meaning that the product 2 is inspected by the inspection camera assembly 16 before hot-pressing. A vertical plate 18 is bolted to the base plate 11 at hot-press station 17. A feeding mechanism 3 for driving the carrier tape 14 forward is provided on the support plate 12, a hot-pressing mechanism 4 is provided on the vertical plate 18, and a buffer mechanism 5 is provided on the feeding plate 13 below the hot-pressing mechanism 4. A cover tape guide mechanism 6 is provided on the vertical plate 18 between the inspection camera assembly 16 and the hot-pressing mechanism 4, which flexibly guides the cover tape 19.

[0042] Of course, it should be noted that during the hot-press packaging process of the carrier tape 14, a carrier tape feeding mechanism is required to feed the carrier tape 14, and a cover tape feeding mechanism is required to feed the cover tape 19. The carrier tape feeding mechanism and the cover tape feeding mechanism are both existing technologies, and the technical solution to be protected in this application is not the specific structure of the carrier tape feeding mechanism and the cover tape feeding mechanism.

[0043] See Figure 4As shown, the feeding mechanism 3 is existing technology, specifically including a feeding motor 31 horizontally fixed to one side of the support plate 12, and a rotating shaft 32 rotatably and horizontally inserted into the support plate 12 on the other side. The feeding motor 31 drives the rotating shaft 32 to rotate via a synchronous belt assembly 33. Vertically arranged feeding ratchet 34 is fixedly connected to both the output shaft of the feeding motor 31 and the rotating shaft 32 on the other side of the support plate 12. The feeding ratchet 34 includes a disc-shaped feeding ratchet body 341 and feeding protrusions 342 evenly distributed on the outer circumference of the feeding ratchet body. When the feeding ratchet 34 rotates, each feeding protrusion 342 sequentially enters the feeding hole 141 of the carrier belt 14, thereby driving the carrier belt 14 forward. To ensure smooth pulling of the carrier belt 14, elastic pressing assemblies 35 are provided on the support plate 12 at both feeding ratchet 34 locations. The carrier belt 14 is pressed against the feeding ratchet body 341 by the elastic pressing assembly 35, thereby stably and periodically conveying the carrier belt 14 forward under the push of the feeding protrusion 342. The feeding mechanism 3 can refer to the structure of the needle wheel and support wheel, pressing roller assembly in the patent publication number CN221247082U, entitled "A Cutting Device", etc., and will not be described in detail here. Of course, in other embodiments, the feeding mechanism 3 may also adopt other existing structures, and the feeding mechanism 3 is not the technical solution to be protected by this utility model.

[0044] See Figure 5 , 6 As shown, the cover guide mechanism 6 includes a sliding plate 61 that is vertically slidably mounted on the upright plate 18. The sliding plate 61 slides on the upright plate 18 via an existing slide rail slider assembly 62. The slide rail slider assembly 62 includes a slide rail that is vertically fixedly connected to the upright plate 18 on the side opposite to the feeding plate 13, and a slider that is fixedly connected to the sliding plate 61 by bolts. The slider is slidably embedded in the slide rail.

[0045] A guide plate 63 is horizontally fixedly connected to the upper end face of the sliding plate 61. The guide plate 63 is provided with an extension horizontal plate 631 extending above the carrier belt 14. A guide groove 632 is provided on the lower end face of the extension horizontal plate 631 to guide the cover strip 19. The cover strip 19, which is sent from above the extension horizontal plate 631, is slidably embedded in the guide groove 632 and then covers the carrier belt 14.

[0046] In order to enable the extension plate 631 to drive the guide plate 63 to move slightly up and down when guiding the cover strip 19, thereby achieving flexible guidance of the cover strip 19 and avoiding the situation in the prior art where the extension plate 631 cannot float up and down, resulting in scratches, jamming, or flipping and twisting of the cover strip 19, a bolt 64 is horizontally fixedly connected to the vertical plate 18 below the sliding plate 61, and a bolt 65 is horizontally fixedly connected to the sliding plate 61. The two ends of the tension spring 66 are respectively hung on the bolt 64 and the bolt 65.

[0047] In order to facilitate the adjustment of the relative position of the extension plate 631 above the carrier belt 14, an oblong adjustment through hole 633 is provided on the extension plate 631 on the guide plate 63 along the horizontal direction perpendicular to the conveying of the carrier belt 14. An adjustment bolt (not shown in the figure) passes through the adjustment through hole 633 and is threaded into the sliding plate 61 to fix the guide plate 63 to the sliding plate 61.

[0048] Furthermore, an extension vertical plate 611 extends upward from the upper end of the sliding plate 61. A clearance groove 612 is formed on the upper end of the extension vertical plate 611 along the direction perpendicular to the conveying belt 14. An adjusting rod 67 is rotatably embedded within the clearance groove 612. The adjusting rod 67 includes a rotating shaft 671 that can rotate within the clearance groove 612, a limiting ring 672 fixedly connected to the rotating shaft 671 inside and outside the clearance groove 612, and an adjusting head 673. The rotating shaft 671 inside the limiting ring 672 is threaded into the guide plate 63. When it is necessary to adjust the relative position of the extension horizontal plate 631, first loosen the adjusting bolt (at this time, the adjusting bolt is only loosened and not disengaged from the guide plate 63), then rotate the adjusting head 673 clockwise or counterclockwise to move the extension horizontal plate 631 to the designated position, and then tighten the adjusting bolt.

[0049] See Figure 7 , 8 As shown, the hot pressing mechanism 4 includes a fixed plate 41 horizontally fixed to the upright plate 18 by bolts, a pressing cylinder 42 fixedly connected to the lower end face of the fixed plate 41, a pressing sleeve 421 fixedly sleeved on the telescopic rod of the pressing cylinder 42, a pressing block 43 set directly below the pressing cylinder 42, two connecting rods 44 vertically connected to the fixed plate 41 by threads, bolts 431 horizontally fixedly inserted on both sides of the pressing block 43 below the connecting rods 44, a tension spring 45 with its two ends respectively hanging on the connecting rods 44 and the bolts 431, a heat insulation block 46 fixedly connected to the lower end face of the pressing block 43, a knife holder 47 fixedly connected to the lower end of the heat insulation block 46, and a hot pressing head 48 detachably fixedly connected to the knife holder 47.

[0050] The lower end face of the pressure sleeve 421 is not fixed to the pressure block 43, but abuts against the pressure block 43 under the tension of the tension spring 45. When the telescopic rod of the pressing cylinder 42 reciprocates at high frequency, thereby driving the hot pressing head 48 to reciprocate for hot pressing and sealing, the tension spring 45 can buffer the hot pressing head 48, avoiding the thermal melting deformation of the carrier tape caused by traditional direct hard hot pressing and sealing without buffer. The heat insulation block 46 is made of heat insulation material, and the existing heating electrode 471 for heating the tool holder 47 and the hot pressing head 48 and the thermocouple 472 for detecting and controlling the heating temperature are inserted in the tool holder 47.

[0051] In order to facilitate the adjustment of the corresponding size of the hot press head 48 according to different carrier belt 14 sizes, the tool holder 47 is an L-shaped structure facing the carrier belt 14, and the hot press head 48 is detachably fixed to the tool holder 47 by bolts.

[0052] To enable the pressing cylinder 42 to drive the hot press head 48 to reciprocate up and down at high frequency for high-frequency hot pressing and sealing of the carrier tape 14, the pressing cylinder 42 is used in conjunction with an existing high-frequency solenoid valve. For easy stopping and starting of the hot pressing and sealing operation, a top plate 49 is horizontally fixed to the vertical plate 18 above the fixed plate 41 by bolts. An actuating cylinder 491 is vertically fixed downwards to the top plate 49. The telescopic rod of the actuating cylinder 491 can slide through the top plate 49 and is connected to the fixed plate 41 via an existing floating joint. To ensure smooth movement of the fixed plate 41 and its components during the reciprocating extension and retraction of the actuating cylinder 491, a linear bearing sleeve 492 is vertically embedded in the fixed plate 41. A guide shaft 493 is fixedly connected to the top plate 49 and slides through the linear bearing sleeve 492. The linear bearing sleeve 492 and the guide shaft 493 constitute the existing linear bearing structure. Of course, it also includes components such as steel balls, retainers, and seals used in conjunction with it.

[0053] See Figure 9 , 10 As shown in Figure 11, the buffer mechanism 5 is located below the carrier belt 14 directly below the hot press head 48. It includes a buffer plate 51 that slides vertically inside the feed plate 13 and a ball plunger 52 that is vertically fixed inside the feed plate 13 below the buffer plate 51. The ball head 521 of the ball plunger 52 abuts against the lower end face of the buffer plate 51.

[0054] Specifically, a buffer groove 132 is provided on the upper surface of the feeding plate 13, and the buffer plate 51 can be vertically slidably embedded in the buffer groove 132. Slots 511 are provided on both sides of the upper surface of the buffer plate 51. Limiting plates 53 are fixedly connected to the feeding plates 13 on both sides of the buffer plate 51. A horizontally arranged protruding plate 531 extends from the inner end face of the limiting plate 53 towards the buffer plate 51. The bottom of the slot 511 abuts against the lower end face of the protruding plate 531 under the elastic force of the ball-head plunger 52. The protruding plate 531 limits the buffer plate 51, preventing it from detaching from the buffer groove 132. The ball-head plunger 52 is existing technology, comprising a plunger sleeve 522 fixedly connected by threads to the feeding plate 13 below the buffer plate 51, a buffer spring 523 embedded in the plunger sleeve 522, and a ball head 511 locked in the plunger sleeve 522 at the upper end of the buffer spring 523.

[0055] With the above structure, when the hot press head 48 moves downward to hot press the carrier tape 14 and cover tape 19, the carrier tape 14, product 2, cover tape 19, and buffer plate 51 will move downward, thereby compressing the buffer spring 523. This buffers the carrier tape 14 and cover tape 19, further avoiding the carrier tape's thermal melting deformation caused by traditional unbuffered direct rigid hot press packaging. Thus, by setting the tension spring 45 and buffer mechanism 5, flexible hot press packaging of the carrier tape 14 and cover tape 19 is achieved, realizing high-frequency hot press packaging while avoiding the carrier tape's thermal melting deformation caused by traditional unbuffered direct rigid hot press packaging.

[0056] Furthermore, in order to adjust the relative position of the limiting plate 53 on the feeding plate 13, a waist-shaped adjustment through hole 532 is provided on the limiting plate 53 along the vertical direction. The adjustment bolt (not shown in the figure) passes through the adjustment through hole 532 and is threaded into the feeding plate 13 to fix the limiting plate 53 on the feeding plate 13.

[0057] The working principle and process of this embodiment are as follows:

[0058] The carrier belt 14 is placed in the feeding cavity formed by the feeding groove 13 of the feeding plate 13 and the pressure plate 15. The feeding protrusion 342 passes through the feeding hole 141 of the carrier belt 14. The feeding motor 31 of the feeding mechanism 3 drives the two feeding ratchet wheels 34 to rotate, thereby driving the carrier belt 14 to move forward. The existing transfer mechanism sequentially transfers the products to the product placement groove 142. The detection camera assembly 16 takes pictures of the product placement groove 142 of the carrier belt 14 through the detection through slot 151 to detect whether the product 2 is correctly placed in the product placement groove 142. The cover belt 19 is fed from the existing cover belt feeding assembly and moves downward through the existing guide assembly and is embedded in the guide slot 632 of the extension cross plate 631. Guided by the guide slot 632, the cover belt 19 and the carrier belt 14 are covered together. After being hot-pressed and sealed by the hot pressing mechanism, the cover belt 19 and the carrier belt 14 are continuously and periodically conveyed forward under the drive of the feeding mechanism 3. The above process is existing technology and will not be described in detail here. The following focuses on describing the working process of the cover belt guide mechanism 6, the hot pressing mechanism 4, and the buffer mechanism 5.

[0059] After the cover strip 19, fed from above the extension plate 631, enters the guide groove 632, it needs to maintain dynamic tension. When the hot-pressing mechanism 4 hot-presses the cover strip 19 and the carrier strip 14, the tension of the cover strip 19 will increase. At this time, the un-hot-pressed cover strip 19 will push up the extension plate 631, causing the sliding plate 61 to move upward a certain distance. At this time, the second tension spring 66 is in a stretched state. After the hot-pressing of the cover strip 19 and the carrier strip 14, the tension of the cover strip 19 will decrease, and the sliding plate 61 and the extension plate 631 will return to their original positions under the tension of the second tension spring 66. By setting the cover strip guide mechanism 6 with a flexible structure, the tension of the cover strip 19 can be kept within a certain range to avoid excessive tension leading to deformation and thus hot-pressing failure.

[0060] When hot pressing is required, the telescopic rod of the actuator cylinder 491 extends to move the fixing plate 41 and the hot pressing head 48 downwards, bringing the hot pressing head 48 close to the cover belt 19 for rapid hot pressing. When hot pressing the cover belt 19 and the carrier belt 14, the telescopic rod of the pressing cylinder 42 extends, moving the pressure sleeve 421 downwards. At this time, the tension spring 45 is stretched, and the hot pressing head 48 abuts against the cover belt 19. As the pressure sleeve 421 continues to move downwards, it moves the cover belt 19, the carrier belt 14, the buffer plate 51, and the ball head 521 downwards to the set position. The heated hot pressing head 48 then completes the hot pressing of the cover belt 19 and the carrier belt 14, fixing them together. Afterwards, the telescopic rod of the pressing cylinder 42 retracts, moving the pressure sleeve 42... 1. The tension spring 45 pulls the pressure block 43, heat insulation block 46, knife holder 47, and hot pressing head 48 upwards, so that the hot pressing head 48 is separated from the hot-pressed cover strip 19. The controller controls the high-frequency solenoid valve to make the telescopic rod of the pressing cylinder 42 extend and retract at high frequency, thereby driving the hot pressing head 48 to move up and down at high frequency, thus completing the high-frequency hot pressing operation on the cover strip 19 and the carrier strip 14. In this process, due to the use of tension spring 45 and ball plunger 52, high-frequency flexible hot pressing of the cover strip 19 and the carrier strip 14 is realized, avoiding the technical problems of frequent rework, affecting production progress and product quality, and failing to meet the dual requirements of efficiency and quality for mass production, which are easily caused by the heat melting deformation of the carrier strip 14 during traditional hot pressing packaging.

[0061] It should be noted that the controller is required in the above working process. It is existing technology. The connection method and working principle of the controller with the detection camera assembly 16, the feeding mechanism 3, the hot pressing mechanism 4 and other components are existing technologies. As long as it can meet the above working process, it is acceptable.
