Technical Field

[0001] The utility model relates to the field of semiconductors, in particular to a tape conveying device used for semiconductor packaging. Background Art

[0002] Semiconductor packaging refers to the process of processing tested wafers into independent chips according to product models and functional requirements. The packaging process is as follows: the wafers from the wafer front-end process are cut into small chips through the dicing process, and then the cut chips are glued to the corresponding substrate (lead frame), and then ultra-fine metal (gold, tin, copper, and aluminum) wires or conductive resins are used to connect the bonding pads of the chips to the corresponding pins of the substrate to form the required circuit; then the independent chips are packaged and protected with plastic shells;

[0003] When packaging a semiconductor, a plastic shell needs to be installed on the semiconductor. When packaging, a tray containing the packaged plastic shell needs to be placed on a packaging device for the packaging device to perform a packaging. However, in most existing technical solutions, staff manually load the tray containing the packaged plastic shell, which makes the loading process extremely troublesome and thus affects the semiconductor packaging efficiency. Utility Model Content

[0004] The embodiment of the present application provides a reel conveyor for semiconductor packaging, thereby solving the technical problem that most of the existing technical solutions require workers to manually load the tray containing the packaging plastic shell, which makes the loading process extremely troublesome and thus affects the efficiency of semiconductor packaging.

[0005] The technical solution adopted in the embodiment of the present application is as follows:

[0006] A tape conveyor for semiconductor packaging, comprising a support frame, a placement slot for conveying a tray, a sliding device for driving the placement slot to move, and a loading device for loading the tray; the placement slot is arranged on the sliding end of the sliding device; the sliding device is arranged on the support frame; the loading device is arranged at one end of the support frame;

[0007] The feeding device includes a bending support plate, a fixing part for fixing the bending support plate, a U-shaped limiting plate for limiting the holding plate, a pushing plate for pushing the holding plate, and a first driving device for driving the pushing plate to move; the fixing part is connected to the bending support plate and the support frame; the U-shaped limiting plate is arranged on the bending support plate; rectangular openings are provided at the bottom of both ends of the U-shaped limiting plate; the pushing plate passes through two groups of the rectangular openings; two groups of the first driving devices are arranged on the bending support plate and are symmetrically arranged with the U-shaped limiting plates; the driving ends of the two groups of the first driving devices are connected to the pushing plate.

[0008] A further technical solution is: the sliding device includes a rack, a support rod arranged on the support frame, a slider for driving the placement groove to move, a second driving device installed on the slider, a gear meshingly connected to the rack, and a limiting slide rail for limiting the sliding of the slider; the rack is arranged on the support rod; the placement groove is arranged on the slider; two groups of symmetrically placed limiting slide rails are arranged on the support frame; the slider slides on the limiting slide rail; the gear is arranged on the second driving device.

[0009] A further technical solution is: the fixing member is a bolt.

[0010] A further technical solution is: the first driving device is a cylinder.

[0011] A further technical solution is: the second driving device is a motor.

[0012] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0013] 1. Due to the use of the support frame, placement slot, sliding device and feeding device, when it is necessary to feed the tray with the encapsulated plastic shell, the staff will first place several trays assembled with the encapsulated plastic shell on the bending support plate in the feeding device in turn, and ensure that each group of trays is against the two ends of the U-shaped limit plate. Then, the sliding device works so that the sliding end of the sliding device moves with the placement slot toward the direction close to the bending support plate, and finally against the front end of the support frame. At this time, the driving ends of the two groups of one driving device in the feeding device are retracted at the same time, so that the push plate slides along the two groups of rectangular openings and pushes the bottom tray, so that the tray is pushed into the placement slot. When the push plate is about to push the tray into the placement slot, the driving ends of the two groups of one driving device extend at the same time, so that the push plate is reset to the original position, and the next tray at the bottom can be pushed. When the containing tray is pushed into the placement slot, the sliding end of the sliding device works, so that the sliding end of the sliding device moves the placement slot with the containing tray to the rear end of the support frame. At this time, the containing tray in the placement slot can be taken out and placed on the packaging equipment. The operation is repeated in sequence to transport each group of containing trays in the loading device. The whole operation process is simple and reliable, which is convenient for the staff to operate.

[0014] 2. Due to the arrangement of a rack, a support rod, a slider, a second drive device, a gear and a limiting slide rail, the gear is driven to rotate by the output shaft of the second drive device. Since the gear is meshed and connected to the rack fixedly connected to the support rod, and the slider fixedly connected to the second drive device is slidably connected to the two sets of limiting slide rails, when the output shaft of the second drive device drives the gear to rotate, the slider can slide back and forth along the two sets of limiting slide rails, thereby enabling the placement slot to move back and forth.

[0020] The embodiment of the present application provides a reel conveyor for semiconductor packaging, thereby solving the technical problem that most of the existing technical solutions require workers to manually load the tray containing the packaging plastic shell, which makes the loading process extremely troublesome and thus affects the efficiency of semiconductor packaging.

[0021] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] A tape conveyor for semiconductor packaging, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a support frame 1, a placement slot 2 for conveying a tray, a sliding device 3 for driving the placement slot 2 to move, and a loading device 4 for loading the tray. The placement slot 2 is arranged on the sliding end of the sliding device 3. The sliding device 3 is arranged on the support frame 1. The loading device 4 is arranged at one end of the support frame 1.

[0024] The feeding device 4 includes a bending support plate 41, a fixing member 42 for fixing the bending support plate 41, a U-shaped limiting plate 43 for limiting the holding tray, a pushing plate 44 for pushing the holding tray, and a first driving device 45 for driving the pushing plate 44 to move. The fixing member 42 is connected to the bending support plate 41 and the support frame 1. The U-shaped limiting plate 43 is arranged on the bending support plate 41. Rectangular openings 431 are provided at the bottom of both ends of the U-shaped limiting plate 43. The pushing plate 44 passes through the two groups of rectangular openings 431. Two groups of first driving devices 45 are arranged on the bending support plate 41, which are symmetrically arranged with the U-shaped limiting plates 43. The driving ends of the two groups of first driving devices 45 are connected to the pushing plate 44.

[0025] The placement groove 2 is fixedly connected to the sliding end of the sliding device 3. The sliding device 3 is fixedly connected to the support frame 1. The feeding device 4 is fixedly installed at the front end of the support frame 1. The fixing member 42 is preferably a bolt. A plurality of groups of fixing members 42 arranged in a linear array are provided on the bending support plate 41. Each group of fixing members 42 passes through the bending support plate 41 and is threadedly connected to the support frame 1. The U-shaped limiting plate 43 is fixedly connected to the top of the bending support plate 41. Rectangular openings 431 are provided at the bottom of the left and right ends of the U-shaped limiting plate 43. A first driving device 45 having two groups of U-shaped limiting plates 43 symmetrically arranged is fixed on the bending support plate 41. The first driving device 45 is preferably a cylinder. The driving ends of the two groups of first driving devices 45 are fixedly connected to the push plate 44.

[0026] Due to the arrangement of the support frame 1, the placement slot 2, the sliding device 3 and the loading device 4, when it is necessary to load the tray with the encapsulated plastic shell, the staff first places a number of trays assembled with the encapsulated plastic shell on the bent support plate 41 in the loading device 4 in sequence, and ensures that each group of trays abuts against the two ends of the U-shaped limit plate 43. Then, through the operation of the sliding device 3, the sliding end of the sliding device 3 moves with the placement slot 2 toward the direction close to the bent support plate 41, and finally abuts against the front end of the support frame 1. At this time, the driving ends of the two groups of one driving device 45 in the loading device 4 are retracted at the same time, so that the push plate 44 slides along the two groups of rectangular openings 431 and pushes the bottom tray, so that the tray is pushed into the placement slot 2. When the push plate 44 is about to push the tray into the placement slot 2, the driving ends of the two groups of one driving device 45 are extended at the same time, so that the push plate 44 is reset to the original position, and the next tray at the bottom can be pushed. When the containing tray is pushed into the placement groove 2, the sliding end of the sliding device 3 works, so that the sliding end of the sliding device 3 moves the placement groove 2 with the containing tray to the rear end of the support frame 1. At this time, the containing tray in the placement groove 2 can be taken out and placed on the packaging equipment. The operation is repeated in sequence to transport each group of containing trays in the loading device 4. The whole operation process is simple and reliable, which is convenient for the staff to operate.

[0027] like Figure 4 As shown, the sliding device 3 includes a rack 31, a support rod 32 arranged on the support frame 1, a slider 33 for driving the placement slot 2 to move, a second driving device 34 installed on the slider 33, a gear 35 meshingly connected to the rack 31, and a limiting slide rail 36 for limiting the sliding movement of the slider 33. The rack 31 is arranged on the support rod 32. The placement slot 2 is arranged on the slider 33. Two groups of symmetrically placed limiting slide rails 36 are arranged on the support frame 1. The slider 33 slides on the limiting slide rail 36. The gear 35 is arranged on the second driving device 34.

[0028] The support rod 32 is fixedly connected to the bottom of the support frame 1. The second driving device 34 is fixedly installed at the bottom of the slider 33. The second driving device 34 is selected as a motor. The gear 35 is fixedly connected to the output shaft of the second driving device 34. The bar 31 is fixedly connected to the support rod 32. The placement groove 2 is fixedly connected to the top of the slider 33. Two sets of symmetrically placed limit rails 36 are fixedly connected to the top of the support frame 1.

[0029] Due to the arrangement of the rack 31, the support rod 32, the slider 33, the second driving device 34, the gear 35 and the limiting slide rail 36, the gear 35 is driven to rotate by the output shaft of the second driving device 34. Since the gear 35 is meshedly connected to the rack 31 fixedly connected to the support rod 32, and the slider 33 fixedly connected to the second driving device 34 is slidably connected to the two sets of limiting slide rails 36, when the output shaft of the second driving device 34 drives the gear 35 to rotate, the slider 33 can slide back and forth along the two sets of limiting slide rails 36, thereby realizing the back and forth movement of the placement slot 2.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.
