Description

Technical Field

[0001] This application relates to the field of wire bonding machine technology, and more specifically, to a track device and a material pulling device. Background Technology

[0002] Existing wire bonding machines mainly consist of a track structure composed of a front rail and a rear rail, a heating component, and grippers. Before the equipment is put into operation, the width of the track structure, i.e. the distance between the front rail and the rear rail, is adjusted. The grippers are used to clamp the sheet and transport it along the inside of the track structure. However, because the rear rail expands and deforms under the heating of the heating component, the width of the track structure changes, resulting in a mismatch between the width of the track structure and the sheet, which affects the wire bonding quality. Utility Model Content

[0003] One of the objectives of this utility model is to provide a track device to solve the technical problem in the prior art where the rear rail expands and deforms after being heated, causing changes in the width distance between the rear rail and the front rail.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a track device, comprising: a front rail and a rear rail parallel to each other, both extending along a first direction and spaced apart in a second direction perpendicular to the first direction, wherein a material pulling channel for moving a feeding sheet is formed between the rear rail and the front rail; the track device further comprises a support frame and an elastic adjustment mechanism, the rear rail being mounted on the side of the support frame near the front rail; the elastic adjustment mechanism connecting the rear rail and the support frame, the elastic adjustment mechanism comprising: a longitudinal elastic element for pushing the rear rail toward the front rail along the second direction, wherein... The longitudinal elastic element is installed between the rear rail and the support frame; a longitudinal fastener is used to restrict the rear rail from separating from the support frame in the second direction, and the longitudinal fastener is connected to the rear rail and the support frame respectively; a vertical elastic element is used to press the rear rail against the support frame in a third direction, and the vertical elastic element is installed on the top of the rear rail; and a vertical fastener is used to restrict the rear rail from separating from the support frame in the third direction, and the vertical fastener is connected to the rear rail and the support frame respectively, the third direction being perpendicular to the first direction and the second direction respectively.

[0005] The technical solution of this utility model has the following advantages: The track device uses an elastic adjustment mechanism to press the rear rail in the second direction and the third direction respectively, so that the rear rail can only deform in the first direction after being heated, so as to ensure that the width dimension between the front rail and the rear rail remains unchanged, eliminating the situation that the width of the track changes due to heating expansion, thereby ensuring the quality of welding wire.

[0006] Furthermore, one end of the longitudinal fastener has a longitudinal threaded portion, and the other end has a longitudinal limiting protrusion that abuts against the rear rail. A longitudinal mounting hole is formed on the support frame, and a longitudinal threaded mating portion that is threadedly engaged with the longitudinal threaded portion is formed inside the longitudinal mounting hole. The vertical fastener has a vertical threaded portion, which extends through the rear rail and is inserted into the support frame. A vertical mounting hole is formed on the support frame, and a vertical threaded mating portion that is threadedly engaged with the vertical threaded portion is formed inside the vertical mounting hole.

[0007] Furthermore, a longitudinal mounting groove is formed on the side surface of the support frame near the front rail, and a longitudinal elastic element is disposed in the longitudinal mounting groove, with the end of the longitudinal elastic element extending out of the longitudinal mounting groove and abutting against the rear rail; a vertical mounting groove is formed on the top surface of the rear rail, and a vertical fastener is disposed in the vertical mounting groove, with the vertical threaded part extending out of the vertical mounting groove and connecting to the support frame, the vertical fastener having a vertical limiting protrusion, and a vertical elastic element sleeved on the vertical fastener, with both ends of the vertical elastic element abutting against the bottom surface of the vertical mounting groove and the vertical limiting protrusion, respectively.

[0008] Furthermore, the support frame includes a support frame body and two fixed blocks connected to the support frame body. The two fixed blocks are divided into a first fixed block and a second fixed block arranged sequentially in the direction of material movement. The first end of the rear rail is connected to the first fixed block through an elastic adjustment mechanism, and the other end is fixedly connected to the first fixed block.

[0009] Furthermore, the first fixing block has an adjustment hole for fixing to the support frame body. The adjustment hole penetrates the top and bottom surfaces of the first fixing block and extends along the second direction.

[0010] Furthermore, it also includes multiple pushing components for abutting against the side wall of the material sheet in the material pulling channel to push the material sheet to move in the second direction. The multiple pushing components are all arranged on the same side of the material pulling channel and are spaced apart sequentially in the direction of material sheet movement.

[0011] Furthermore, an assembly groove for mounting a pusher assembly is formed on the rear rail. The pusher assembly includes a pusher component for abutting against the sheet, a pusher fixing member fixed in the assembly groove, and a pusher elastic member connecting the pusher component and the pusher fixing member. A connecting hole is formed on the inner wall of the rear rail for inserting the end of the pusher component into the pulling channel.

[0012] Furthermore, the pusher assembly also includes a pusher cover plate for restricting the pusher component from moving out of the assembly slot in a third direction, the pusher cover plate being fixed above the pusher component.

[0013] Furthermore, the bottom of the material feeding channel is equipped with multiple support blocks, each of which contains a heating component, and each support block has a corresponding pusher component on one side.

[0014] Another objective of this utility model is to provide a material pulling device that solves the technical problem in the prior art where the track and the material sheet do not match due to the deformation caused by heating expansion.

[0015] To achieve this objective, the present invention provides a material pulling device, including a base, on which the aforementioned track device is provided, the front rail of the track device being supported on the top of the base, and the support frame of the track device being fixed on the base.

[0016] This material pulling device can prevent the track from becoming mismatched with the material due to thermal expansion and deformation, thus ensuring the quality of wire bonding. Attached Figure Description

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0031] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0032] like Figures 1 to 11As shown, the track device 101 provided in this embodiment includes: a front rail 20 and a rear rail 30 that are parallel to each other. The front rail 20 and the rear rail 30 both extend along a first direction D1 (the direction D1 shown in the figure, hereinafter referred to as the first direction D1) and are spaced apart in a second direction D2 (the direction D2 shown in the figure, hereinafter referred to as the second direction D2) that is perpendicular to the first direction D1. A material pulling channel 100a for moving the feeding piece 200 is formed between the rear rail 30 and the front rail 20. The track device 101 also includes a support frame 40 and an elastic adjustment mechanism 50. The rear rail 30 is installed on the side of the support frame 40 near the front rail 20. The elastic adjustment mechanism 50 connects the rear rail 30 and the support frame 40 respectively. The elastic adjustment mechanism 50 includes: a longitudinal elastic element 51 for moving along the second direction. D2 pushes the rear rail 30 towards the front rail 20. The longitudinal elastic element 51 is installed between the rear rail 30 and the support frame 40. The longitudinal fastener 52 is used to restrict the rear rail 30 from separating from the support frame 40 in the second direction D2. The longitudinal fastener 52 is connected to the rear rail 30 and the support frame 40 respectively. The vertical elastic element 53 is used to press the rear rail 30 against the support frame 40 along the third direction D3 (D3 direction shown in the figure, hereinafter referred to as the third direction D3). The vertical elastic element 53 is installed on the top of the rear rail 30. The vertical fastener 54 is used to restrict the rear rail 30 from separating from the support frame 40 in the third direction D3. The vertical fastener 54 is connected to the rear rail 30 and the support frame 40 respectively. The third direction D3 is perpendicular to the first direction D1 and the second direction D2 respectively.

[0033] The aforementioned track device 101 employs an elastic adjustment mechanism 50. A longitudinal elastic element 51 pushes the rear rail 30 towards the front rail 20 along the second direction D2; a longitudinal fastener 52 restricts the rear rail 30 from separating from the support frame 40 in the second direction D2; a vertical elastic element 53 presses the rear rail 30 against the support frame 40 along the third direction D3; and a vertical fastener 54 restricts the rear rail 30 from separating from the support frame 40 in the third direction D3. In this way, the width and thickness of the rear rail 30 are less prone to deformation after heating, with deformation only occurring in its length. This eliminates the possibility of width changes due to thermal expansion of the track, resulting in a more stable track structure composed of the front rail 20 and the rear rail 30, thus ensuring the quality of the welding wire.

[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0035] See 1 and Figure 2The material pulling device 100 provided in this embodiment includes a base 10 and a track device 101 supported on the base 10. The base 10 has a first direction D1, a second direction D2, and a third direction D3 that are perpendicular to each other. The track device 101 includes a front rail 20 and a rear rail 30 disposed on the top of the base 10. The front rail 20 and the rear rail 30 both extend along the first direction D1 and are spaced apart in the second direction D2. A material pulling channel 1 for the movement of the feeding sheet 200 is formed between the rear rail 30 and the front rail 20. In this embodiment, a transfer device 60 is provided on the base 10 to move the material sheet 200 in the material pulling channel 100a along the first direction D1. The transfer device 60 is installed on one side of the front rail 20. The material pulling channel 100a has an inlet end and an outlet end arranged sequentially in the first direction D1. It is easy to understand that after the material sheet 200 enters the material pulling channel 100a through the inlet end, the transfer device 60 will drive the material sheet 200 to move towards the outlet end in the material pulling channel 100a.

[0036] In this embodiment, the transfer device 60 includes a transfer bracket 61, a gripper 62 for holding the sheet 200, and a translation drive assembly 63 that enables the gripper 62 to move. The transfer bracket 61 can be fixedly installed on the base 10 by any existing fixing method such as screws or welding. The front rail 20 can be fixedly installed on the transfer bracket 61 by any existing fixing method such as screws or welding. The translation drive assembly 63 is, but is not limited to, a motor screw drive assembly, which is supported inside the transfer bracket 61. The gripper 62 is movably installed on the transfer bracket 61 along the first direction D1 and is located on one side of the front rail 20. The gripper 62 is connected to the translation drive assembly 63. Thus, under the drive of the translation drive assembly 63, the gripper 62 causes the feed end of the sheet 200 to move towards the discharge end in the feeding channel 100a along the first direction D1. It is worth mentioning that the aforementioned gripper 62 is any existing gripper in the prior art that can clamp the sheet 200.

[0037] See Figure 1 and Figure 2 The material feeding channel 100a provided in this embodiment has a support block 70 at its bottom. The support block 70 is equipped with a heating component (not shown in the figure). In this embodiment, the number of support blocks 70 is, but not limited to, three. The three support blocks 70 are arranged sequentially along the first direction D1. The support block 70 is equipped with a heating component for heating the material sheet 200.

[0038] See Figures 1 to 3The support frame 40 provided in this embodiment is fixed on the base 10. The rear rail 30 is installed on the side of the support frame 40 near the front rail 20. An elastic adjustment mechanism 50 is provided between the rear rail 30 and the support frame 40. The elastic adjustment mechanism 50 can be uniformly arranged on the rear rail 30 near the feed end, or uniformly arranged on the rear rail 30 near the discharge end, or arranged in the middle of the rear rail 30. The elastic adjustment mechanism 50 includes: a longitudinal elastic element 51, used to push the rear rail 30 towards the front rail 20 along the second direction D2. The longitudinal elastic element 51 is installed on the rear rail 30. Between the rear rail 30 and the support frame 40; longitudinal fasteners 52, used to restrict the rear rail 30 from separating from the support frame 40 in the second direction D2, the longitudinal fasteners 52 are connected to the rear rail 30 and the support frame 40 respectively; vertical elastic elements 53, used to press the rear rail 30 against the support frame 40 in the third direction D3, the vertical elastic elements 53 are installed on the top of the rear rail 30; and vertical fasteners 54, used to restrict the rear rail 30 from separating from the support frame 40 in the third direction D3, the vertical fasteners 54 are connected to the rear rail 30 and the support frame 40 respectively, the third direction D3 3 is perpendicular to the first direction D1 and the second direction D2 respectively. In this embodiment, the number of elastic adjustment mechanisms 50 is, but not limited to, one set. One set of elastic adjustment mechanisms 50 is installed on the rear rail 30 near the feed end. The part of the rear rail 30 near the feed end is fixed to the support frame 40 with fasteners such as screws and bolts. It can be understood that one end of the rear rail 30 is movably connected to the support frame 40 through the elastic adjustment mechanism 50, and the other end is fixedly connected to the support frame 40 with fasteners. The longitudinal elastic element 51 pushes the rear rail towards the front rail 20 along the second direction D2. 30, and the rear rail 30 is pressed against the support frame 40 along the third direction D3 by the vertical elastic element 53. In this way, when the rear rail 30 expands due to heat, the rear rail 30 will be pressed by the longitudinal elastic element 51 and the vertical elastic element 53 in the second direction D2 and the third direction D3 respectively, so that the rear rail 30 can only deform along the first direction D1. This can reduce the risk of deformation of the rear rail 30 in the second direction D2 and the third direction D3, so as to ensure that the track width dimension (i.e. the width dimension between the front rail 20 and the rear rail 30) remains unchanged, making the track structure more stable.

[0039] See Figures 3 to 9The longitudinal fastener 52 and vertical fastener 54 provided in this embodiment can be fixed on the support frame 40 or on the rear rail 30. In this embodiment, both the longitudinal fastener 52 and the vertical fastener 54 are fixed on the support frame 40. One end of the longitudinal fastener 52 has a longitudinal threaded portion 521, and the other end has a longitudinal limiting protrusion 522 that abuts against the rear rail 30. The support frame 40 has a longitudinal mounting hole 421, and a longitudinal threaded mating portion that is threadedly engaged with the longitudinal threaded portion 521 is formed in the longitudinal mounting hole 421. The vertical fastener 54 has a vertical threaded portion 541, which extends out of the rear rail 30 and is inserted into the support frame 40. The support frame 40 has a vertical mounting hole 422, and a vertical threaded mating portion that is threadedly engaged with the vertical threaded portion 541 is formed in the vertical mounting hole 422. It is easy to understand that after the longitudinal fastener 52 is fixedly connected to the support frame 40 through the longitudinal threaded portion 521, it holds the rear rail 30 on the support frame 40 in the second direction D2. Under the elastic force of the longitudinal elastic element 51, the rear rail 30 is pressed against the longitudinal limiting protrusion 522. After the vertical fastener 54 is fixedly connected to the support frame 40 through the vertical threaded portion 541, it holds the rear rail 30 on the support frame 40 in the third direction D3. Under the elastic force of the vertical elastic element 53, the rear rail 30 is pressed against the support frame 40.

[0040] In other embodiments, both the longitudinal fastener 52 and the vertical fastener 54 can be fixedly mounted on the rear rail 30 after passing through the support frame 40.

[0041] See Figure 5 , Figure 6 , Figure 8 and Figure 9 In this embodiment, a longitudinal mounting groove 423 is formed on the side surface of the support frame 40 near the front rail 20. The longitudinal elastic element 51 is, but is not limited to, a spring. The longitudinal elastic element 51 is disposed in the longitudinal mounting groove 423, and the end of the longitudinal elastic element 51 extends out of the longitudinal mounting groove 423 and abuts against the rear rail 30 to apply elastic force to the rear rail 30. A vertical mounting groove 31 is formed on the top surface of the rear rail 30. A vertical fastener 54 is disposed in the vertical mounting groove 31, and the vertical threaded part 541 extends out of the vertical mounting groove 31 and connects to the support frame 40. The vertical fastener 54 has a vertical limiting protrusion 542. The vertical elastic element 53 is, but is not limited to, a spring. The vertical elastic element 53 is sleeved on the vertical fastener 54, and the two ends of the vertical elastic element 53 abut against the bottom surface of the vertical mounting groove 31 and the vertical limiting protrusion 542, respectively, to apply elastic force to the rear rail 30.

[0042] In another embodiment, the longitudinal elastic element 51 may be fitted onto the longitudinal fastener 52.

[0043] In another embodiment, the vertical elastic element 53 is located on one side of the vertical fastener 54, and it can be mounted on the rear rail 30 and abut against the support frame 40, or mounted on the support frame 40 and abut against the rear rail 30.

[0044] Please continue reading Figures 3 to 9 In this embodiment, the support frame 40 includes a support frame body 41 and two fixing blocks 42 and 43 connected to the support frame body 41. The support frame body 41 can be fixedly installed on the base 10 by any existing fixing method such as screws or welding. The two fixing blocks 42 and 43 are arranged sequentially as a first fixing block 42 and a second fixing block 43 in the moving direction of the material sheet 200. The first end of the rear rail 30 is connected to the first fixing block 42 through an elastic adjustment mechanism 50, and the other end is fixedly connected to the first fixing block 42. The longitudinal mounting hole 421 and the vertical mounting hole 422 are both formed on the first fixing block 42.

[0045] In another embodiment, the support frame body 41 is integrally formed with the fixing blocks 42 and 43.

[0046] In another embodiment, the elastic adjustment mechanism 50 is disposed between the rear rail 30 and the second fixing block 43.

[0047] from Figures 5 to 7 As can be seen, in this embodiment, the first fixing block 42 has an adjustment hole 424 for fixing to the support frame body 41. The adjustment hole 424 is, but is not limited to, a waist-shaped hole. The adjustment hole 424 penetrates the top and bottom surfaces of the first fixing block 42 and extends along the second direction D2. In this way, the position of the first fixing block 42 can be adjusted in the second direction D2, thereby adjusting the position of the rear rail 30.

[0048] See Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 10 and Figure 11 The track device 101 provided in this embodiment also includes a plurality of pushing components 80. The pushing components 80 are used to abut against the side wall of the material sheet 200 in the material pulling channel 100a to push the material sheet 200 to move along the second direction D2. The pushing components 80 can be installed on the rear rail 30 or on the front rail 20. The plurality of pushing components 80 are arranged on the same side of the material pulling channel 100a. In this embodiment, the number of pushing components 80 is not limited to three, corresponding to the heating components in the three support blocks 70 respectively. That is, one pushing component 80 is provided on one side of each support block 70. The three pushing components 80 are all installed on the rear rail 30 and are spaced apart in sequence in the moving direction of the material sheet 200 (i.e., the first direction D1).

[0049] from Figure 1 and11 As can be seen, in this embodiment, an assembly groove 32 for mounting the pusher assembly 80 is formed on the rear rail 30. The pusher assembly 80 includes a pusher component 81 for abutting against the sheet 200, a pusher fixing member 82 fixed in the assembly groove 32, and a pusher elastic member 83 connecting the pusher component 81 and the pusher fixing member 82. The pusher component 81 is movably mounted in the assembly groove 32 along the second direction D2. The pusher component 81 has an arc-shaped protrusion protruding toward the pull channel 100a. The pusher fixing member 82 can be fixedly mounted in the assembly groove 32 by means of, but not limited to, threads, and is used to support the pusher elastic member 83. The pusher elastic member 83 is, but not limited to, a spring. A connecting hole 33 is formed on the inner wall of the rear rail 30 for the end of the pusher component 81 to be inserted into the pull channel 100a. The connecting hole 33 connects the assembly groove 32 and the pull channel 100a. Thus, under the elastic push of the pusher 83, the surface of the arc-shaped protrusion extends into the material pulling channel 100a and abuts against the side wall of the sheet 200, pressing the sheet 200 against the front rail 20. It should be noted that after the sheet 200 enters the material pulling channel 100a, the pusher assembly 80 pushes the sheet 200 onto the front rail 20 along the second direction D2. As the gripper 62 of the transfer device 60 clamps the sheet 200 and moves within the material pulling channel 100a, the three pusher assemblies 80 abut against the sheet 200 respectively, pressing the sheet 200 against the front rail 20 while it moves, until the sheet 200 leaves the material pulling channel 100a, thereby preventing the sheet 200 from shifting during movement and allowing it to move smoothly within the material pulling channel 100a.

[0050] In another embodiment, the pusher assembly 80 is mounted on the front rail 20 and is able to press the sheet 200 against the rear rail 30.

[0051] See Figure 11 In this embodiment, the pusher assembly 80 also includes a pusher cover plate 84 for restricting the pusher component 81 from moving out of the assembly groove 32 along the third direction D3. The pusher cover plate 84 is fixed above the pusher component 81 (the upper part in the figure) with screws, so as to prevent the pusher component 81 from moving upward and sliding out of the assembly groove 32.

[0052] Please return to the previous page. Figure 2 In this embodiment, a lifting seat 91 is provided in the middle of the material pulling channel 100a. The middle support block 70 of the three support blocks 70 is installed on the lifting seat 91. A power component 92 is provided on the base 10, which can drive the lifting seat 91 to move in the third direction D3. The power component 92 is, but is not limited to, a motor. In this way, under the drive of the power component 92, the base 10 can be raised and lowered relative to the base 10 along the third direction D3, thereby adjusting the height position of the middle support block 70.
