Description

Technical Field

[0001] This utility model relates to the technical field of carrier tape overlap, and in particular to a carrier tape overlap fixture. Background Technology

[0002] Carrier tape is a strip-shaped material used to carry and transport electronic components (such as chips, resistors, capacitors, etc.). It is usually made of plastic (such as PS, PC) and has pockets on its surface for placing the components. In automated production, carrier tape needs to be overlapped to achieve continuous feeding of front and rear rolls.

[0003] When splicing new and old carrier tapes, adhesive methods are typically used. For example, high-temperature resistant tape (such as polyimide tape) is used to bond the back sides (non-component sides) of both ends of the carrier tape. When using this method to splice carrier tapes, it is essential to ensure the accuracy of the overlap between the two sections of carrier tape; otherwise, problems such as tape jamming or incorrect material handling may occur during transmission.

[0004] Currently, carrier tape splicing technology relies on operator experience, which can easily lead to precision problems such as misalignment of carrier tape drive holes, causing production stoppages. Therefore, there is an urgent need for a technology that can accurately splice carrier tapes. Utility Model Content

[0005] The purpose of this utility model is to provide a carrier belt overlap fixture to overcome the shortcomings of related technologies, which can accurately connect new and old carrier belts and improve the yield of carrier belt overlap.

[0006] To achieve one of the above objectives, this utility model provides a carrier belt overlap fixture, comprising:

[0007] The worktable is provided with at least one limiting rail, the limiting rail having a receiving groove and support surfaces located on both sides of the receiving groove along its length, and the limiting rail having a positioning post for cooperating with the transmission hole of the carrier belt.

[0008] The pressure plate assembly includes at least two spaced-apart overlapping pressure plates, which are arranged along the length of the limiting track and are movably connected to the worktable. Each overlapping pressure plate has a pressing portion for engaging with the support surface, and the pressing portion has an insertion hole for engaging with the positioning post.

[0009] In one embodiment of this application, two adjacent limiting rails are provided, which are respectively referred to as the first limiting rail and the second limiting rail. The first limiting rail cooperates with the overlapping pressure plate, and the second limiting rail is provided with a first cutting groove, which is perpendicular to the second limiting rail.

[0010] The pressure plate assembly also includes a cutting pressure plate, which is movably connected to the worktable. The cutting pressure plate cooperates with the second limiting rail, and the cutting pressure plate is provided with a second cutting groove corresponding to the first cutting groove.

[0011] The carrier belt overlap fixture also includes a cutting assembly, which includes a cutter movably disposed along the extension direction of the first cutting groove and / or the second cutting groove.

[0012] In one embodiment of this application, the cutting assembly further includes a connecting rod fixed to the workbench and an operating plate slidably connected to the connecting rod. The axial direction of the connecting rod is the same as the extension direction of the first cutting groove, and the cutter is fixed to the side of the operating plate facing the workbench.

[0013] In one embodiment of this application, the operation panel is provided with a mounting groove, one side of the mounting groove is open, and the cutter is connected to a mounting block, which engages with the mounting groove.

[0014] In one embodiment of this application, an elastic member is provided between the operation panel and the worktable. One end of the elastic member abuts against the operation panel, and the other end abuts against the worktable. When the elastic member is in its natural state, the blade of the cutter is located in the first cutting groove. When the elastic member is under compression, the blade of the cutter passes through the first cutting groove and extends into the second cutting groove.

[0015] In one embodiment of this application, the elastic element includes a sleeve that is slidably sleeved on the connecting rod and springs fixed at both ends of the sleeve.

[0016] In one embodiment of this application, a protective cover is provided on the side of the cutting plate away from the second limiting track, and at least part of the protective cover covers the second cutting groove in the extending direction of the second cutting groove.

[0017] In one embodiment of this application, the worktable is provided with a support boss, and the pressure plate assembly includes an edge portion that is magnetically attracted to the support boss.

[0018] In one embodiment of this application, the support boss is provided with a clearance groove, which is located between the two overlapping pressure plates.

[0019] In one embodiment of this application, the overlapping pressure plate and the cutting pressure plate are hinged to the workbench, and both the overlapping pressure plate and the cutting pressure plate are provided with a protruding plate, which extends to the outside of the workbench along the length direction of the limiting track.

[0020] Compared with related technologies, this utility model adopts the combination of a limiting track and a pressure plate assembly. When the carrier belt is overlapped, the carrier belt can be fixed on the limiting track, and then the pressure plate assembly is used to limit the carrier belt. The positioning post in the limiting track can accurately cooperate with the transmission hole on the carrier belt, so that the carrier belt will not shift or move during the overlap process, thereby improving the accuracy of the carrier belt overlap.

[0021] Furthermore, this utility model is equipped with adjacent first and second limiting tracks, which can precisely limit the carrier belt between the first limiting track and the overlapping pressure plate, or between the second limiting track and the cutting pressure plate. The cutting component can be used to cut the carrier belt between the second limiting track and the cutting pressure plate.

[0022] The fixture provided by this utility model enables high-precision cutting and bonding of new and old carrier tapes, effectively ensuring the accuracy of the overlapping process of new and old carrier tapes. Attached Figure Description

[0030] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The terms "first," "second," "third," "fourth," etc., used in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Furthermore, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, a connection can be a direct connection or an indirect connection through an intermediate medium; it can be a fixed connection, a movable connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] To enable those skilled in the art to better understand the technical solutions of this utility model, the appendices in the embodiments of this utility model will be described below. Figure 1 -5. The technical solutions in the embodiments of this utility model are clearly and completely described.

[0033] One embodiment of this utility model provides a carrier tape splicing fixture for achieving precise splicing of new and old carrier tapes. In related technologies, the carrier tape structure includes multiple element grooves protruding from one surface to the other, evenly arranged along the length of the carrier tape. On one side of the carrier tape along its length, the width of one side is greater than the width of the other side, and multiple transmission holes are evenly arranged along the length of the side with the greater width.

[0034] Reference Figures 1 to 3 The carrier belt overlap fixture includes a worktable 10 and a pressure plate assembly 20 movably mounted on the worktable 10. The worktable 10 is provided with a limit track. When performing the overlap operation on the carrier belt, the carrier belt can be fixed on the limit track, and the pressure plate assembly 20 is used to limit the carrier belt, so that the carrier belt will not shift or move during the overlap process, thereby improving the accuracy of the carrier belt overlap.

[0035] At least one limiting rail is provided on the worktable 10. The limiting rail includes a receiving groove 311 and support surfaces 312 located on both sides of the receiving groove 311 along its length. The receiving groove 311 is formed by an inward recess from the surface of the worktable 10. The receiving groove 311 is configured as a long strip-shaped through groove structure. The receiving groove 311 is used to receive the component receiving groove portion of the carrier tape, and the support surfaces 312 are used to support the extended portions on both sides of the component receiving groove. The width of the support surface 312 on one side of the receiving groove 311 is greater than the width of the support surface 312 on the other side, so that the support surfaces 312 on both sides of the receiving groove 311 can be adapted to the shape and structure of the carrier tape.

[0036] The limiting track is equipped with positioning posts 313, which are used to cooperate with the transmission holes on the carrier belt to accurately position the carrier belt. Several positioning posts 313 are arranged along the length of the limiting track and are set on the wide support surface 312.

[0037] When overlapping the carrier belt, place it with one side of the carrier belt element's groove facing down in the limiting track, and engage the transmission hole on the carrier belt with the positioning post 313. Because the shape and size of the positioning post 313 and the spacing between adjacent positioning posts 313 are adapted to the transmission hole on the carrier belt, the carrier belt can be accurately fixed and limited within the limiting track, making the overlap of the carrier belt more precise.

[0038] The pressure plate assembly 20 includes at least two spaced-apart overlapping pressure plates 21, which are arranged along the length of the limiting track. Each overlapping pressure plate 21 has a pressing portion 211 that mates with the support surface 312, and the pressing portion 211 has an insertion hole 212 for mates with the positioning post 313. The overlapping pressure plates 21 are movably connected to the worktable 10 and can move relative to the worktable 10 along a preset movement path R.

[0039] During the movement of the overlapping pressure plate 21 along the preset moving path R, the overlapping pressure plate 21 has a pressing position that fits against the worktable 10. At the pressing position, the pressing part 211 cooperates with the limiting rail, and a gap is left between the pressing part 211 and the supporting surface 312 to accommodate the edge position of the carrier belt. The pressing part 211 fits against the surface of the carrier belt, and the insertion hole 212 is inserted into the positioning post 313. Under the combined limiting action of the limiting rail and the overlapping pressure plate 21, the new and old carrier belts can be reliably fixed, and the spacing between the new and old carrier belts can be precisely adjusted.

[0040] This embodiment sets up two independent overlapping pressure plates 21, with an operating space reserved between the two overlapping pressure plates 21. When the overlapping pressure plate 21 is connected to the limiting rail, the limiting rail located at the operating space position is not covered. The position where the new and old carrier tapes need to be overlapped can be set at the position corresponding to the position of the limiting rail and the operating space. Then, the overlapping pressure plate 21 is moved to the pressing position, and the position where the new and old carrier tapes need to be overlapped is exposed at the operating space position, which is convenient for the staff to bond the new and old carrier tapes.

[0041] In some embodiments, the two overlapping pressure plates 21 can be integrally set, and an operating groove is provided at the middle position of the two overlapping pressure plates 21. The position of the operating groove corresponds to a part of the limiting track. When the overlapping pressure plate 21 is in the pressing position, the overlapping position of the new and old carrier tapes is exposed in the operating groove, which makes it convenient for the staff to bond the new and old carrier tapes.

[0042] In some embodiments, the overlapping pressure plate 21 is hinged to the worktable 10, and the overlapping pressure plate 21 is located on one side of the limiting rail. The two overlapping pressure plates 21 are respectively hinged to the worktable 10, and the aforementioned preset movement path R is set as an arc-shaped movement path with the hinge as the axis. The overlapping pressure plate 21 rotates and displaces along the preset movement path R. After the new and old carrier belts are respectively engaged on the limiting rail, the overlapping pressure plate 21 is rotated, causing the overlapping pressure plate 21 to rotate and adhere to the worktable 10, thus limiting the movement of the carrier belt.

[0043] In some embodiments, the overlap plate 21 is detachably connected to the workbench 10, for example, by fasteners or magnetic attraction. After removing the overlap plate 21, the carrier belt can be fixed to the limiting rail, and then the overlap plate 21 can be connected to the workbench 10 to fix the new and old carrier belts.

[0044] In some embodiments, the worktable 10 is provided with two adjacent limiting rails, which are arranged parallel to each other. Both limiting rails extend along a first direction and are arranged in a second direction, which is perpendicular to the first direction.

[0045] The two limiting tracks are referred to as the first limiting track 31 and the second limiting track 32, respectively. The first limiting track 31 cooperates with the overlapping pressure plate 21 to achieve bonding between the new and old carrier tapes. The second limiting track 32 is further provided with a first cutting groove 321 on the basis of the first limiting track 31. The first cutting groove 321 is arranged through the worktable 10 along a third direction, which is perpendicular to the first and second directions. The first cutting groove 321 is used to cooperate with the structure for cutting new and old carrier tapes to achieve precise cutting of the carrier tapes.

[0046] The following is a detailed explanation of the structure of the carrier tape overlap fixture for cutting new and old carrier tapes.

[0047] Reference Figure 4 and Figure 5 The carrier belt overlap fixture includes a cutting assembly 40 movably connected to the worktable 10. The cutting assembly 40 includes a cutter 41 movably disposed along the extension direction of the first cutting groove 321, and the cutter 41 cooperates with the first cutting groove 321, and the cutter 41 can reciprocate in the first cutting groove 321.

[0048] The pressure plate assembly 20 also includes a cutting pressure plate 22, which is movably connected to the worktable 10. The cutting pressure plate 22 cooperates with the second limiting rail 32 to limit and fix the new and old carrier belts. In the first direction, the length of the cutting pressure plate 22 is the same as the length of the worktable 10.

[0049] The cutting plate 22 is also provided with a pressing part 211 and a insertion hole 212. The pressing part 211 on the cutting plate 22 is used to cooperate with the support surface 312 on the second limiting track 32 to limit and fix the carrier belt. The insertion hole 212 on the cutting plate 22 is used to be inserted into the positioning post 313 on the second limiting track 32.

[0050] The cutting plate 22 can be hinged to the worktable 10. The cutting plate 22 moves relative to the worktable 10 along a preset arc-shaped moving path F. During the movement of the cutting plate 22 along the preset moving path F, the cutting plate 22 has a pressing position that fits against the worktable 10. At the pressing position, the pressing part 211 cooperates with the limiting rail. A gap is left between the pressing part 211 and the support surface 312 to accommodate the edge position of the carrier tape. The pressing part 211 fits against the surface of the carrier tape, and the insertion hole 212 is inserted into the positioning post 313.

[0051] The cutting plate 22 can be hinged to the workbench 10, and the cutting plate 22 is located on the side of the workbench 10 away from the overlapping plate 21. The preset movement path F and the preset path R are symmetrically arranged about the center line axis of the workbench 10 along the first direction. The movement paths of the cutting plate 22 and the overlapping plate 21 are opposite.

[0052] A second cutting groove 221 is provided on the cutting pressure plate 22, and the position of the second cutting groove 221 matches the position of the first cutting groove 321 and the cutter 41. The second cutting groove 221 is provided through the cutting pressure plate 22 in a direction perpendicular to the cutting pressure plate 22. When the cutting pressure plate 22 is in the pressing position, the extending direction of the second cutting groove 221 is the same as the extending direction of the first cutting groove 321.

[0053] When the carrier tape is fixed on the second limiting rail 32, the cutting pressure plate 22 is flipped to the pressing position, and the carrier tape is limited between the second limiting rail 32 and the cutting pressure plate 22, with the carrier tape located at the opening positions of the first cutting groove 321 and the second cutting groove 221 facing each other. When the cutter 41 moves upward in the third direction, it passes through the opening positions of the first cutting groove 321 and the second cutting groove 221, allowing for precise cutting of the carrier tape.

[0054] The aforementioned cutter 41, first cutting groove 321 and second cutting groove 221 are all provided in two parallel parts, and are arranged at intervals in the first direction. This allows for simultaneous cutting of the new and old carrier tapes, ensuring that the cut ends of the new and old carrier tapes are more uniform, reducing cutting errors and facilitating subsequent bonding and overlapping operations.

[0055] In some embodiments, the cutter 41 is slidably mounted on the worktable 10, and an operating plate 43 is floatingly connected to the worktable 10. The operating plate 43 moves closer to or further away from the worktable 10 along a third direction, and the two cutters 41 are fixed to the side of the operating plate 43 facing the worktable 10. A connecting rod 42 is fixedly connected to the side of the worktable 10 away from the limiting track, and the operating plate 43 is slidably mounted on the connecting rod 42. The axial direction of the connecting rod 42 is the same as the extension direction of the first cutting groove 321.

[0056] When it is necessary to operate the cutting of the carrier tape, the operating plate 43 is moved towards the worktable 10 in the third direction. The operating plate 43 drives the cutter 41 to move towards the cutting pressure plate 22, so that the cutter 41 passes through the slot of the first cutting groove 321 and enters the second cutting groove 221. In this way, the cutting of new and old carrier tapes can be achieved quickly.

[0057] To ensure the cutter 41 can quickly return to its original position after the carrier tape is cut, an elastic element 44 is provided between the operating plate 43 and the worktable 10. The elastic element 44 is sleeved on the connecting rod 42, with one end abutting against the worktable 10 and the other end abutting against the operating plate 43. In its natural state, the cutting edge of the cutter 41 is located within the first cutting groove 321. In a compressed state, the cutting edge of the cutter 41 passes through the first cutting groove 321 and extends into the second cutting groove 221.

[0058] The elastic element 44 includes a sleeve 441 and springs 442 connected to both ends of the sleeve 441. Both the sleeve 441 and the springs 442 are slidably sleeved on the connecting rod 42, and the axes of the sleeve 441 and the springs 442 both extend upward in a third direction. The operating plate 43 and the worktable 10 are respectively provided with connecting grooves that mate with the two springs 442 on their opposite sides.

[0059] Because the spring 442 has a helical structure, it is difficult for it to completely fit with the connecting rod 42 in the circumferential direction. If the length of the spring 442 is relatively long, the operating plate 43 will inevitably wobble in the circumferential direction of the spring 442. However, the sleeve 441 can fit more precisely with the connecting rod 42 to limit the displacement of the operating plate 43, so that the operating plate 43 moves only in the third direction. This allows the operating plate 43 to drive the cutter 41 to cut the carrier tape more accurately.

[0060] Furthermore, the springs 442 at both ends of the sleeve 441 have a short stroke, which ensures that the cutter 41 can fully cut the carrier tape while avoiding excessive travel of the cutter 41, thus achieving accurate and fast cutting of the carrier tape.

[0061] During the cutting of the carrier tape, to ensure operational safety, a protective cover 222 is provided on the side of the cutting pressure plate 22 away from the second limiting rail 32. At least part of the protective cover 222 covers the second cutting groove 221 in the extension direction of the second cutting groove 221. With this arrangement, even if the blade of the cutter 41 passes through the second cutting groove 221, it will not be directly exposed on the surface of the cutting pressure plate 22, preventing accidental injury to the operator.

[0062] In some embodiments, the cutter 41 may also be slidably disposed on the cutting pressure plate 22, as long as the cutter 41 can move back and forth in the extension direction of the first cutting groove 321 or the second cutting groove 221. This embodiment does not specifically limit the connection position of the cutter 41.

[0063] In some embodiments, the cutter 41 is detachably fixed to the operating plate 43, which has a mounting groove 431 extending in a second direction, with one side of the groove open. The cutter 41 is connected to a mounting block 411, which engages with the mounting groove 431. The cross-sections of the mounting block 411 and the mounting groove 431 can be T-shaped or I-shaped. Through the cooperation of the mounting block 411 and the mounting groove 431, the installation and removal of the cutter 41 from the operating plate 43 can be conveniently and quickly achieved, facilitating the replacement of the cutter 41.

[0064] To ensure a more reliable connection between the pressure plate assembly 20 and the worktable 10, a support boss 11 is provided on the worktable 10, and the support boss 11 is located on one side of the limiting rail. When two limiting rails are provided on the worktable 10, the support boss 11 is located between the first limiting rail 31 and the second limiting rail 32, and the overlapping pressure plate 21 and the cutting pressure plate 22 are provided with edge portions 213 that cooperate with the support boss 11.

[0065] The support boss 11 and the edge portion 213 are magnetically attracted to each other. For example, a magnet 111 is fixed on the support boss 11, and the edge portion 213 is made of magnetic material, or a magnetic strip opposite to the magnetic pole of the magnet 111 is provided on the edge portion 213. When the overlapping pressure plate 21 and the cutting pressure plate 22 are connected to the worktable 10, the edge portion 213 is tightly fitted to the support boss 11 under the action of magnetic attraction, so that the overlapping pressure plate 21 and the cutting pressure plate 22 reliably limit the carrier belt.

[0066] Please refer to again Figure 3 The supporting boss 11 has a relief groove 112 on the side facing the overlapping pressure plate 21, and the relief groove 112 is located between the two overlapping pressure plates 21. The relief groove 112 can provide operating space for the new and old carrier tapes during bonding, which facilitates the bonding operation of the two sections of carrier tape.

[0067] Both the overlapping pressure plate 21 and the cutting pressure plate 22 are provided with protruding plates 214, which extend along the length of the limiting track to the outside of the worktable 10. The protruding plates 214 on the two overlapping pressure plates 21 are arranged opposite to each other. When the overlapping pressure plate 21 and the cutting pressure plate 22 are engaged with the surface of the worktable 10, the overlapping pressure plate 21 and the cutting pressure plate 22 can be flipped by operating the protruding plates 214, which facilitates the separation of the overlapping pressure plate 21 and the cutting pressure plate 22 from the worktable 10.

[0068] In the carrier belt overlap fixture provided by this utility model, the carrier belt can be precisely limited between the first limiting track 31 and the overlap pressure plate 21, or between the second limiting track 32 and the cutting pressure plate 22, so as to realize the precise cutting and overlap operation of the new and old carrier belts and improve the accuracy of the overlap of the new and old carrier belts.

[0069] When it is necessary to cut the overlap between the new and old carrier tapes, the new and old carrier tapes are respectively fixed between the second limiting rail 32 and the cutting pressure plate 22, and the cutting assembly 40 can precisely cut the new and old carrier tapes. After the new and old carrier tapes are cut, they are moved between the first limiting rail 31 and the overlap pressure plate 21. The specific position of the new and old carrier tapes in the first limiting rail 31 can be adjusted according to the required overlap position, so that the overlap of the new and old carrier tapes is exposed in the operating space between the two overlap pressure plates 21.

[0070] During the carrier tape splicing process, the carrier tape splicing fixture enables high-precision cutting and bonding of the new and old carrier tapes, effectively ensuring the accuracy of the splicing process.

[0071] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
