Description

Technical Field

[0001] The present invention relates to the technical field of semiconductor packaging, and in particular to a crystal bonding device, an inclined guide frame material storage device and a material loading method. Background Art

[0002] Semiconductor packaging refers to the process of converting tested wafers into individual chips according to product model and functional requirements. The front-end packaging process is typically completed by die bonding equipment, which uses vision-guided technology to automatically pick chips from wafers and bond them to lead frames.

[0003] The crystal bonding equipment is usually equipped with a hopper, which is equipped with a trough opened in the vertical direction. The staff can put the frames into the trough one by one, so that multiple frames can be stacked in sequence, making it easier for the crystal bonding equipment to clamp or absorb the frames.

[0004] However, with the development of semiconductor technology, various types of special-shaped frames have emerged. The center of gravity of the special-shaped frames often deviates from the center of the supporting plane of the special-shaped frames. Therefore, if the special-shaped frames are stacked vertically in the trough, they are prone to tipping over when the number of stacked special-shaped frames reaches a certain level. For example, Figure 1 As shown, the frame unit 01 is Z-shaped, with the bottom surface of the support portion 02 serving as the support plane, and the suspended portion 03 suspended above the support portion 02. When multiple frame units 01 are stacked, their center of gravity is located on the suspended portion 03, causing the suspended portion 03 of the upper frame unit 01 to abut against the suspended portion 03 below. As the number of stacked frame units 01 increases, the tilt of the upper frame unit 01 becomes more severe, eventually causing the entire frame to topple.

[0005] Therefore, it is necessary to improve the existing technology to solve the technical problem that multiple frames in the existing technology are prone to tipping over when stacked. Summary of the Invention

[0006] The object of the present invention is to provide a crystal bonding device, an inclined guided frame material storage device and a material loading method, so as to solve the technical problem in the prior art that multiple frames are prone to tipping over when stacked.

[0007] To achieve this object, the present invention adopts the following technical solutions:

[0008] An inclined guide frame material storage device, comprising:

[0009] Frame lifting device;

[0010] A tilt limiting device, wherein the tilt limiting device is provided with a frame receiving groove;

[0011] A frame support device, the frame support device is slidably connected to the frame accommodating groove along the groove length direction of the frame accommodating groove, and the frame support device is connected to the lifting end of the frame lifting device;

[0012] The groove is tilted in the longitudinal direction so that the horizontal distance from the center of gravity of each frame unit in the frame accommodating groove to the suspended portion of the lowest frame unit gradually increases from bottom to top.

[0013] Optionally, the tilt limiting device includes a limiting bottom plate, a first limiting portion and a second limiting portion arranged opposite to each other, and the frame accommodating groove is formed between the first limiting portion and the second limiting portion;

[0014] The first limiting portion is rotatably connected to the limiting bottom plate, and the second limiting portion is rotatably connected to the limiting bottom plate.

[0015] Optionally, the first limiting portion and the second limiting portion both include an angle adjustment member, and the angle adjustment member is rotatably connected to the limiting base plate;

[0016] The angle adjustment member is further connected to a width adjustment member, and the width adjustment member can adjust the slot width of the frame accommodating slot relative to the angle adjustment member.

[0017] Optionally, the frame support device includes a frame mounting plate, and the frame mounting plate is rotatably connected to an outer roller and an inner roller respectively;

[0018] The outer roller is arranged on the outer side of the tilt limiting device and abuts against the outer wall of the tilt limiting device; the inner roller is arranged in the frame accommodating groove and abuts against the groove wall of the frame accommodating groove.

[0019] Optionally, a roller swing arm is connected between the frame mounting plate and the inner roller; one end of the roller swing arm is rotatably connected to the frame mounting plate, and the other end of the roller swing arm is rotatably connected to the inner roller.

[0020] Optionally, a limit guide rail unit is installed at the lifting end of the frame lifting device, the limit guide rail unit is arranged in a horizontal direction, and the frame mounting plate is slidably connected to the limit guide rail unit.

[0021] A feeding method, applied to the above-mentioned inclined guide frame storage device, comprises:

[0022] The frame units are stacked on the frame support device in sequence along the length direction of the frame accommodating groove, so that the center of gravity of each frame unit in the frame accommodating groove increases gradually from bottom to top, and the horizontal distance to the suspended part of the lowest frame unit increases gradually.

[0023] A feeding device, comprising the above-mentioned inclined guided frame storage device, further comprising:

[0024] Conveyor track components;

[0025] A frame suction assembly, the frame suction assembly being used to suck the frame unit in the frame receiving groove;

[0030] The present invention provides a solid crystal device, an inclined guided frame storage device and a loading method. During loading, a plurality of frame units are stacked in sequence on a frame support device along the slot length direction. Since the frame units are stacked in sequence along the slot length direction of the frame accommodating slot, the center of gravity of each frame unit in the frame accommodating slot increases gradually from bottom to top, and the horizontal distance to the suspended portion of the lowest frame unit, that is, the stacked plurality of frame units are tilted as a whole. At the same time, the center of gravity of the plurality of frame units is distributed along the slot length direction, which avoids the situation where the center of gravity acts on the gap to cause tipping when the plurality of centers of gravity are distributed in the vertical direction. The above arrangement makes it difficult for the stacked frame units to tip over, and the frame units can remain parallel to each other, without the need for additional rotating structure to correct the position of the frame units, thereby solving the problem of multiple frame units tipping over easily when stacked in a low-cost manner.

[0060] Example 1

[0061] The inclined guide frame stocking device provided in this embodiment is applied to the loading device in the die bonding equipment to temporarily store the frame units 01 so that the loading device can feed the frame units 01 into the die bonding equipment one by one. By improving the structure of the inclined guide frame stocking device, it can complete the storage of general regular-shaped frames and also complete the storage of regular-shaped frames such as Figure 1 The storage of the special-shaped frame in the embodiment of the present invention ensures that the above-mentioned frame unit 01 will not tip over when storing the material in a low-cost manner.

[0062] like Figures 2 to 3 As shown, the inclined guided frame storage device of this embodiment includes a supporting base plate 100; a frame lifting device 200 installed on the supporting base plate 100; wherein, the lifting direction of the frame lifting device 200 can be set vertically or parallel to the slot length direction, without specific limitation, as long as it can push the frame unit 01 to rise; an inclined limiting device 300, the inclined limiting device 300 is provided with a frame accommodating slot 301; a frame supporting device 400, the frame supporting device 400 is slidingly connected to the frame accommodating slot 301 along the slot length direction, and the frame supporting device 400 is connected to the lifting end of the frame lifting device 200; wherein, the slot length direction is inclined, so that the center of gravity of each frame unit 01 in the frame accommodating slot 301 gradually increases from bottom to top, and the horizontal distance to the suspended part 03 of the lowest frame unit 01 gradually increases.

[0063] Next, the working principle of the inclined guided frame storage device is explained using a “Z”-shaped frame unit 01 . The frame unit 01 includes a supporting portion 02 and a suspended portion 03 , and its center of gravity is located at the suspended portion 03 .

[0064] The specific loading method is as follows: along the wall of the frame receiving groove 301, that is, along the groove length direction of the frame receiving groove 301, the frame units 01 are stacked on the frame support device 400 in sequence, so that the frame units 01 are all in contact with the groove wall of the frame receiving groove 301, so that the center of gravity of each frame unit 01 in the frame receiving groove 301 increases from bottom to top, and the horizontal distance to the suspended portion 03 of the lowest frame unit 01 gradually increases. Figure 3 and Figure 4As shown, the frame unit 01 can enter the frame accommodating groove 301 through the notch of the frame accommodating groove 301. Since the frame accommodating groove 301 is arranged at an angle, the left ends of the multiple frame units 01 stacked in sequence are all in contact with the groove wall of the frame accommodating groove 301, that is, the multiple frame units 01 stacked are arranged at an angle from the lower right to the upper left. Therefore, each time a frame unit 01 is stacked, the center of gravity of the frame unit 01 will deviate to the left by a certain size, that is, the higher the number of layers of the frame unit 01, the farther its center of gravity is from the center of gravity of the frame unit 01 on the bottom layer, which plays a role in balancing the center of gravity and avoiding all weight being concentrated on the gap between the two suspended parts 03. Therefore, even if the number of stacked frame units 01 continues to increase, the frame unit 01 as a whole will not fall over, and the suspended parts 03 of the two adjacent frame units 01 can still leave a gap, which is convenient for the loading equipment to uniformly remove the frame unit 01 from the frame accommodating groove 301.

[0065] Therefore, when loading the inclined guided frame storage device, multiple frame units 01 can be stacked in sequence on the frame support device 400 along the groove wall of the frame accommodating groove 301, that is, along the groove length direction; since the frame units 01 are stacked in sequence along the groove wall of the frame accommodating groove 301, that is, the frame units 01 are stacked in sequence along the groove length direction of the frame accommodating groove 301, one end of the frame unit 01 will abut against the groove wall of the frame accommodating groove 301, and the frame accommodating groove 301 is inclined, so the stacked multiple frame units 01 are inclined as a whole, and at the same time, the center of gravity of the multiple frame units 01 is distributed along the groove length direction, avoiding the situation where the center of gravity acts on the gap and causes tipping when multiple centers of gravity are distributed in the vertical direction; the above arrangement makes it difficult for the stacked frame units 01 to tip over, and there is no need to additionally invest in a rotating structure to correct the position of the frame units 01, thereby solving the problem of multiple frame units 01 tipping over easily when stacked in a low-cost manner.

[0066] Furthermore, if Figures 8 and 9 As shown, the tilting limiting device 300 includes a limiting base plate 302, a first limiting portion and a second limiting portion arranged opposite to each other, with a frame receiving groove 301 formed between the first limiting portion and the second limiting portion; the first limiting portion is rotatably connected to the limiting base plate 302, and the second limiting portion is rotatably connected to the limiting base plate 302. The space between the first limiting portion and the second limiting portion allows the lifting end of the frame lifting device 200 to be raised and lowered, which has the advantage of a compact structure. Furthermore, the operator can adjust the angle of the first limiting portion and the second limiting portion relative to the limiting base plate 302 as needed to adjust the tilt angle of the frame receiving groove 301. This allows the device to accommodate a variety of frame units 01 with different center of gravity arrangements, thereby improving the versatility of the tilting guided frame storage device.

[0067] Furthermore, both the first and second limiting portions include an angle adjustment member 303 rotatably connected to the limiting base plate 302. The angle adjustment member 303 is also connected to a width adjustment member 304 capable of adjusting the width of the frame receiving slot 301 relative to the angle adjustment member 303. The width adjustment member 304 can be provided with an adjustment slot, and the angle adjustment member 303 can be provided with an adjustment hole. Bolts can be passed through the adjustment slots and connected to the adjustment holes to achieve width adjustment of the width adjustment member 304 relative to the angle adjustment member 303.

[0068] It should be added that a first optical fiber detection unit 305 is also provided on one side of one of the limiting parts. The first optical fiber detection unit 305 is used to detect whether there is still a frame unit 01 left in the frame accommodating groove 301. The angle adjustment plate 306 is rotatably connected to the limiting part, and the angle adjustment is achieved by means of bolts cooperating with the adjustment groove.

[0069] Furthermore, if Figures 3 to 5 As shown, the frame support device 400 includes a frame mounting plate 401, which is rotatably connected to an outer roller 402 and an inner roller 403. The outer roller 402 is disposed on the outer side of the tilt limiter 300 and abuts against the outer wall of the tilt limiter 300. The inner roller 403 is disposed in the frame receiving groove 301 and abuts against the groove wall of the frame receiving groove 301. The arrangement of the outer roller 402 and the inner roller 403 ensures the stability of the frame support device 400 sliding along the frame receiving groove 301. It should be noted that the two pulleys on either side of the groove wall act as point positioning for the groove wall. The angle between the frame mounting plate 401 and the lifting direction remains unchanged. In this embodiment, the angle between the frame mounting plate 401 and the lifting direction is 90 degrees, that is, the frame mounting plate 401 is always horizontal, so that the supported frame units 01 are all arranged horizontally.

[0070] Furthermore, a roller swing arm 404 is connected between the frame mounting plate 401 and the inner roller 403. One end of the roller swing arm 404 is rotatably connected to the frame mounting plate 401, and the other end of the roller swing arm 404 is rotatably connected to the inner roller 403. The provision of the roller swing arm 404 allows the relative position between the outer roller 402 and the inner roller 403 to be adjusted. When the inclination angle of the frame receiving groove 301 changes, the angle between the frame mounting plate 401 and the lifting direction can be adjusted again to match different frame units 01 by simply adjusting the angle between the roller swing arm 404 and the frame mounting plate 401. Among them, the roller swing arm member 404 is provided with an adjustment slot, and an inner roller bracket 405 is connected between the frame mounting plate 401 and the roller swing arm member 404. The inner roller bracket 405 is provided with an adjustment hole for the bolt to pass through the adjustment slot and connect with the adjustment hole. When the roller swing arm member 404 needs to be adjusted, the adjustment can be completed by loosening the bolt; after the adjustment is completed, the bolt is tightened so that the bolt presses the roller swing arm member 404 and the inner roller bracket 405, thereby completing the fixation of the roller swing arm member 404 relative to the inner roller bracket 405.

[0071] Furthermore, if Figure 6 and Figure 7 As shown, the lifting end of the frame lifting device 200 is installed with a limit rail unit 201, which is arranged in the horizontal direction, and the frame mounting plate 401 is slidably connected to the limit rail unit 201. This makes the movement of the frame mounting plate 401 smoother when it rises.

[0072] Next, the specific structure of the frame lifting device 200 is described. Figures 6 and 7 As shown, it includes a lifting motor 202, which is fixed to a lifting base plate 203 installed on the supporting base plate 100, and the lifting motor 202 drives the lifting unit 208 to move up and down in the form of a screw pair by driving the ball screw 207 to rotate, wherein the limiting guide rail unit 201 is installed on the lifting unit 208, and the lifting unit 208 is slidably connected to the lifting base plate 203 through the lifting guide rail 204; that is, the lifting motor 202 drives the limiting guide rail unit 201 to move up and down through the ball screw 207, thereby driving the frame mounting plate 401 to move up and down, and when the frame mounting plate 401 is lifted and lowered, it is affected by the frame support device 400 and the tilt limiting device 300, so that the frame mounting plate 401 slides on the horizontal plane along the limiting guide rail unit 201 to ensure that each frame unit 01 can be against the groove wall of the frame accommodating groove 301. In addition, the lifting unit 208 is connected to a zero point detection piece 205, and two first photoelectric switches 206 are provided on the lifting base plate 203. The position of the zero point detection piece 205 is detected by the first photoelectric switch 206, and the position of the lifting unit 208 can be corrected to improve the position accuracy.

[0073] In summary, the inclined guided frame storage device of this embodiment can improve production stability at a low cost, and also has the advantages of high adjustability, compact structure, and strong versatility.

[0074] Example 2

[0075] like Figure 2 As shown, the feeding equipment of this embodiment includes the inclined guide frame storage device in the first embodiment, and further includes:

[0076] Conveyor track assembly 500;

[0077] The frame suction assembly 600 is used to suck the frame unit 01 in the frame receiving groove 301;

[0078] Frame transport assembly 700, the moving end of the frame transport assembly 700 is connected to the frame suction assembly 600 to move the sucked frame unit 01 to the conveying track assembly 500;

[0079] The frame pushing assembly 800 is used to push the frame unit 01 on the conveying track assembly 500 into the next process.

[0080] Among them, Figure 10 and Figure 11 As shown, the conveyor track assembly 500 includes three spaced support bars 504, which form two tracks on which two frame units 01 can be placed simultaneously, achieving a dual loading function for a fast single-row frame unit 01. The support bars 504 are connected by an adjustable guide shaft 505, which can adjust the width of the track. The adjustable guide shaft 505 is sequentially connected to a fiber adjustment member 503, a fiber fixing member 502, and a second fiber detection unit 501. By adjusting the guide shaft 505 and the fiber adjustment member 503, the position of the fiber fixing member 502 can be adjusted, thereby changing the position of the second fiber detection unit 501. The second fiber detection unit 501 is used to detect whether the frame unit 01 has been fed out of the conveyor track assembly 500. Through the above arrangement, the present loading equipment can simultaneously complete the loading of two frame units 010, greatly improving the equipment's UPH.

[0081] like Figure 12 and Figure 13As shown, the frame suction assembly 600 includes a support base 601 installed on the transport end of the frame transport assembly 700, and the support base 601 is fixedly connected to the slide cylinder 608 through the cylinder adjustment support 603, and the slide cylinder 608 is connected to the suction cup guide shaft 606 through the transition connection 602, and the suction cup guide shaft 606 is installed with a suction cup mounting part 604, and the suction cup mounting part 604 is installed with a suction cup unit 605 and a frame limiting pin 607, the suction cup unit 605 is used to absorb the frame unit 01, and the frame limiting pin 607 is used to offset the frame unit 01 when sucking the frame unit 01 to prevent the frame unit 01 from deformation.

[0082] like Figure 14 As shown, the frame transport assembly 700 includes a transport support plate 701, on which a transport motor 702, a transport ball screw 703 and a transport guide rail 705 are installed. The screw slider 704 is threadedly connected to the transport ball screw 703 through a screw pair, the screw slider 704 is slidingly connected to the transport guide rail 705, and the support base 601 is fixedly connected to the screw slider 704; that is, the transport ball screw 703 is driven to rotate by the transport motor 702, thereby driving the screw slider 704 to slide, and then driving the frame suction assembly 600 to move back and forth between the inclined guided frame storage device and the conveying track assembly 500.

[0083] like Figure 15 As shown, the frame pusher assembly 800 includes a pusher support plate 801, which is equipped with a motor. The motor, through a synchronous pulley 802 and a synchronous belt 804, drives a pusher slider 805 to slide between two support bars 504, in coordination with a pusher guide rail 803. Frame push pins 806 are mounted on the pusher slider 805 via push pin adjustment seats 807. This drives the frame push pins 806 to protrude from the conveyor track assembly 500 and slide back and forth, pushing the frame unit 01 into the next device (which can be a bonding device in a die bonder).
