Description

Technical Field

[0001] The utility model relates to chip production and testing equipment, in particular to chip burning equipment. Background Art

[0002] Chip burning is divided into two types: offline burning and online burning. Offline burning: usually refers to "bare die burning". Before the MCU chip is attached to the PCB board, it is placed on the programmer with the corresponding adapter for burning. Offline burning is equivalent to making the peripheral circuits and equipment required for chip burning (such as power supply and JLINK) on the offline programmer. After the chip is placed in the adapter and powered on, a basic burning environment is formed. The corresponding program can be burned through some extended functions of the PC or the programmer itself. With the development of technology, the existing chip burning operations are divided into manual burning, semi-automatic burning and fully automatic burning. When burning chips in large quantities, batch semi-automatic or automatic burning equipment is generally used. Semi-automatic or automatic burning equipment generally uses an automated transfer mechanism to transfer chips and an automated positioning mechanism to position the burned chips. The transfer mechanism uses at least one chip transfer head and drives it to pick up and place the burned chips in the horizontal and vertical directions and transfer them to at least one automated positioning mechanism. The automated positioning mechanism includes a chip positioning seat, which is provided with a burning point for placing the chip and a pressing mechanism for pressing the chip in the burning point from above. The bottom of the burning point is provided with a transfer block for connecting the solder ball on the transfer chip and the test point on the test circuit board. The pressed burning chip can be burned.

[0003] However, there are many chip specifications and styles. When burning chips of different specifications, the limit specifications of the burning points need to be changed accordingly, and components such as the chip positioning seat, adapter block and test circuit board need to be replaced. The chip positioning seat only relies on the burning point itself to limit the chip in the horizontal direction, which will leave gaps and cannot achieve precise positioning. In long-term use, some horizontal positioning inaccuracies will inevitably occur, increasing the probability of repairing and replacing the adapter block. Some equipment uses mobile limiting of the two adjacent sides of the chip in the burning point, but it also requires the addition of two independent drive sources, which makes the structure complicated. Existing chip burning equipment requires the replacement of many structural parts when burning chips of different specifications, resulting in low production efficiency and complex precise limit structure. Utility Model Content

[0004] The utility model provides a chip burning device, which solves the problem that the existing chip burning device has many structural parts to replace when burning chips of different specifications, reduces production efficiency, and has a complex precise limit structure.

[0005] The present invention solves the technical problem by adopting a technical solution: a chip programming device comprising a transfer mechanism for transferring chips and a chip positioning mechanism for positioning the chips.

The first and second elastic resistance limiting mechanisms are driven to expand during vertical downward movement of the drive rod and elastically tighten during vertical upward movement of the drive rod. The chip positioning seat can precisely position chips of different specifications, reducing the need to replace chip positioning mechanism components when programming chips of different specifications. The elastic resistance limiting mechanism for the restrained chip eliminates the chip's movement, thereby improving the accuracy of the programming connection point connection.

[0006] Furthermore, the first elastic interference limit mechanism is driven by the drive rod to expand its limit range during vertical downward movement and elastically reduce its limit range during vertical upward movement. The second elastic interference limit mechanism is driven by the first elastic interference limit mechanism to expand its limit range when the first elastic interference limit mechanism expands its limit range, and elastically reduces its limit range when the first elastic interference limit mechanism reduces its limit range. By reducing the number of drive sources through linkage, the structure becomes more compact and the control and setting difficulty and cost are reduced.

The first elastic member is located within the first stretching rod limiting guide groove, with both ends of the first elastic member respectively fixed to the bottom of the first stretching rod limiting guide groove and the corresponding end of the first elastic stretching rod and in a stretched state. A drive movement groove is provided on the upper side of the frame limiting groove for driving the docking block to move horizontally relative to the programming point. By providing a linkage structure with the drive rod, the elastic limiting range is expanded during the process of placing the detected chip in the programming point, and the elastic limiting range is gradually elastically reduced after the detected chip is placed in the programming point, thereby achieving elastic limiting of the corresponding two sides of the detected chip.

[0008] Furthermore, the second elastic interference limit mechanism includes a connecting block, a second elastic interference rod, a second elastic stretching rod, a second elastic member and a linkage guide block, the two ends of the connecting block are respectively vertically fixedly connected to one end of the second elastic interference rod and the second elastic stretching rod, the second elastic interference rod and the second elastic stretching rod are horizontally arranged in parallel, and a driving groove penetrating in a horizontal direction is provided on the second elastic interference rod, the linkage guide block includes a fixed end that passes through the driving groove and is vertically fixedly connected to the main frame and a driving end located in the driving groove, the driving end and the driving groove are correspondingly provided with a first driving inclined surface and a second driving inclined surface that match, and when the main frame drives the first elastic interference rod away from the burning acupuncture point, the driving end drives the second elastic interference rod to move away from the burning acupuncture point The elastic resistance rod is spaced away from the programming point.

DETAILED DESCRIPTION

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1 A chip burning device shown in the figure includes a transfer mechanism for transferring chips and a chip positioning mechanism for positioning chips, the chip positioning mechanism includes at least one chip positioning seat 100, the chip positioning seat 100 is provided with a burning point 110 for placing the chip, the transfer mechanism is provided with at least one chip transfer head 210 driven by it to move in the vertical direction, and the side walls adjacent to the burning point 110 on the chip positioning seat 100 are provided with a first elastic resistance limit mechanism 300 and a second elastic resistance limit mechanism 400 for elastically resisting and limiting the horizontal directions of two adjacent sides of the burned chip respectively, a drive rod 220 is vertically fixed on one side of the chip transfer head 210, the first elastic resistance limit mechanism 300 and the second elastic resistance limit mechanism 400 are driven to expand by the drive rod 220 during the vertical downward movement and elastically tightened during the vertical upward movement of the drive rod 220.

[0026] In a specific implementation, the chip transfer head 210 is a vacuum adsorption head mechanism; first, the transfer mechanism drives the chip transfer head 210 to transfer the chip to be burned to the top of the burning point 110 on the chip positioning seat 100;

[0027] Then, the transfer mechanism drives the chip transfer head 210 to move downward. During the downward movement of the chip transfer head 210, the driving rod 220 is driven downward by the transfer mechanism along with the chip transfer head 210. During the downward movement of the driving rod 220, the lower end of the driving rod 220 drives the first elastic interference limiting mechanism 300 and the second elastic interference limiting mechanism 400 to expand, thereby expanding the limiting range. When the chip transfer head 210 moves downward to place the chip into the burning point 110, the first elastic interference limiting mechanism 300 and the second elastic interference limiting mechanism 400 expand to not contact the chip in the burning point 110.

[0028] Then, after the chip transfer head 210 places the chip into the programming hole 110, the transfer mechanism drives the chip transfer head 210 to move upward and reset;

[0029] During the upward movement of the chip transfer head 210, the driving rod 220 is driven upward by the transfer mechanism along with the chip transfer head 210. During the upward movement of the driving rod 220, the first elastic interference limiting mechanism 300 and the second elastic interference limiting mechanism 400 are elastically reset to tighten the limiting range. After the chip transfer head 210 is moved upward and reset, the first elastic interference limiting mechanism 300 and the second elastic interference limiting mechanism 400 respectively elastically limit the two adjacent sides of the chip being programmed in the horizontal direction, and cooperate with the other two directions of the programming point 110 to complete the elastic limitation of the chip being programmed.

[0030] A transfer block is provided at the bottom of the programming point 110 for connecting the solder balls on the transfer chip with the test points on the test circuit board. After the chip to be programmed completes the high-precision elastic limitation in the horizontal direction, the chip to be programmed is pressed against the transfer block at the bottom of the programming point 110 by other structures on the chip positioning mechanism and programming can be performed. In a specific implementation, if the chip is relatively thin, in order to improve the stability of the elastic limitation, a clearance groove can also be provided at the corresponding positions of the transfer block and the first elastic interference limiting mechanism 300 and the second elastic interference limiting mechanism 400 to facilitate the stable limitation of the chip to be programmed.

[0031] When chips of different specifications need to be tested, the chip positioning seat 100 only needs to replace the adapter block and the test circuit board accordingly, and there is no need to replace the horizontal limiting structure of the chip.

[0032] The driving source is reduced by the linkage of the driving rod 220 fixedly disposed on one side of the chip transfer head 210 .

[0033] The chip positioning seat 100 can accurately limit the chips of different specifications, reducing the need to replace the chip positioning mechanism components when burning chips of different specifications, and elastically limit the limited chip so that the chip has no room for movement, and the burning conduction point docking accuracy is higher.

[0034] On the basis of the above, if Figure 1 As shown, the first elastic interference limiting mechanism 300 is driven by the driving rod 220 to expand its limiting range during the vertical downward movement, and elastically reduces its limiting range during the vertical upward movement of the driving rod 220. The second elastic interference limiting mechanism 400 is driven by the first elastic interference limiting mechanism 300 to expand its limiting range when the first elastic interference limiting mechanism 300 expands its limiting range, and elastically reduces its limiting range when the first elastic interference limiting mechanism 300 reduces its limiting range. By reducing the number of driving sources through linkage, the structure is more compact, and the control and setting difficulty and cost are reduced.

[0035] On the basis of the above, if Figures 1 to 7 As shown, the first elastic interference limiting mechanism 300 includes a main frame 310, a first elastic interference rod 320, a first elastic stretching rod 330, a first elastic member 340 and a driving docking block 350, the first elastic interference rod 320 and the first elastic stretching rod 330 are fixed horizontally and vertically on one side of the main frame 310, the driving docking block 350 is vertically fixed on the upper surface of the main frame 310 and can be driven by the driving rod 220 to move horizontally in the direction away from the burning acupuncture point 110, the chip positioning mechanism is provided with a positioning seat placement groove for fixing and limiting the chip positioning seat 100, and a frame limiting groove 131 for limiting the horizontal movement of the main frame 310 relative to the burning acupuncture point 110 is provided on one side wall of the chip positioning seat 100, the frame One side of the frame limiting groove 131 is provided with a first contact rod limiting guide groove 132 that penetrates the burning point 110 and is used to limit the horizontal movement of the first elastic contact rod 320. One side of the frame limiting groove 131 is provided with a first stretching rod limiting guide groove 133 located outside the burning point 110 and used to limit the horizontal movement of the first elastic stretching rod 330. The first elastic member 340 is located in the first stretching rod limiting guide groove 133. The two ends of the first elastic member 340 are respectively fixed to the bottom of the first stretching rod limiting guide groove 133 and the corresponding end of the first elastic stretching rod 330 and are in a stretched state. The upper side of the frame limiting groove 131 is provided with a driving moving groove 134 for driving the docking block 350 to move horizontally relative to the burning point 110.

[0036] In this specific embodiment, the first elastic member 340 is a spring; when the first elastic interference limiting mechanism 300 is installed on the chip positioning seat 100, one end of the first elastic member 340 is first fixed to one end of the first elastic stretching rod 330 located in the first stretching rod limiting guide groove 133, and then the first elastic interference limiting mechanism 300 is correspondingly inserted from the frame limiting groove 131 to the preset position, and the other end of the first elastic member 340 is fixed to the bottom of the first stretching rod limiting guide groove 133 to complete the basic installation of the first elastic interference limiting mechanism 300. When the chip positioning seat 100 is fixed to the positioning seat installation groove by screws, the first elastic interference limiting mechanism 300 can be prevented from falling out of the chip positioning seat 100;

[0037] In a specific implementation, when the driving docking block 350 is not in contact with the driving rod 220, the first elastic member 340 is in a stretched state, exerting a force on the first elastic stretching rod 330 toward the bottom of the first stretching rod limiting guide groove 133. The first elastic stretching rod 330 drives the first elastic interference rod 320, which contacts the chip, to move horizontally into the programming point 110 through the main frame 310. The first interference rod limiting guide groove 132 allows the first elastic interference rod 320 to slide horizontally relative to the programming point 110 and limits the first elastic interference rod 320 to ensure that the first elastic interference rod 320 remains horizontal during the movement.

[0038] When the driving rod 220 moves downward to drive the driving docking block 350 to move horizontally away from the burning acupoint 110, the driving docking block 350 drives the first elastic abutting rod 320 to move away from the burning acupoint 110 through the main frame 310. When the driving rod 220 moves downward to a preset position, the end of the first elastic abutting rod 320 that abuts against the chip leaves the inside of the burning acupoint 110. At this time, the first elastic member 340 is further stretched but is within the effective deformation range.

[0039] When the driving rod 220 moves upward, the first elastic member 340 is in a stretched state and applies a force toward the bottom of the first stretching rod limiting guide groove 133 to the first elastic stretching rod 330. The first elastic stretching rod 330 drives the first elastic interference rod 320, which contacts the chip, to move horizontally into the programming point 110 through the main frame 310. The first interference rod limiting guide groove 132 allows the first elastic interference rod 320 to slide horizontally relative to the programming point 110 and limits the first elastic interference rod 320 to ensure that the first elastic interference rod 320 remains horizontal during the movement.

[0040] That is, when the chip transfer head 210 moves down to place the chip to be burned on the burning hole 110, the first elastic resistance rod 320 leaves the burning hole 110 under the drive of the driving rod 220. When the chip transfer head 210 moves up to reset, the first elastic resistance rod 320 gradually enters the burning hole 110 as the driving rod 220 moves up until the chip to be burned is elastically resisted into the burning hole 110.

[0041] By setting a linkage structure with the driving rod 220, the elastic limit range is expanded during the process of placing the detected chip on the burning acupoint 110, and the elastic limit range is gradually elastically reduced after the detected chip is placed on the burning acupoint 110, thereby achieving elastic limitation of the two corresponding sides of the detected chip.

[0042] On the basis of the above, if Figures 1 to 7As shown, the second elastic interference limit mechanism 400 includes a connecting block 410, a second elastic interference rod 420, a second elastic stretching rod 430, a second elastic member 440 and a linkage guide block 450, the two ends of the connecting block 410 are respectively vertically fixedly connected to one end of the second elastic interference rod 420 and the second elastic stretching rod 430, the second elastic interference rod 420 and the second elastic stretching rod 430 are horizontally arranged in parallel, and a driving groove 421 passing through the second elastic interference rod 420 is provided. The linkage guide block 450 includes a fixed end vertically fixedly connected to the main frame 310 through the driving groove 421 and a driving end located in the driving groove 421, the driving end and the driving groove 421 are correspondingly provided with a first driving inclined surface and a second driving inclined surface that match, and when the main frame 310 drives the first elastic interference rod 320 away from the burning acupuncture point 110, the driving end drives the second elastic interference rod 320 to move away from the burning acupuncture point 110. The rod 420 is away from the burning point 110, and the side wall of the chip positioning seat 100 away from the first elastic stretching rod 330 is provided with a mounting groove 141 for the horizontal movement of the connecting block 410, the second elastic interference rod 420, the second elastic stretching rod 430 and the linkage guide block 450. One side of the mounting groove 141 is provided with a second interference rod limiting guide groove 142 that penetrates the burning point 110 and is used to limit the horizontal movement of the second elastic interference rod 420. One side of the mounting groove 141 is provided with a second stretching rod limiting guide groove 143 located outside the burning point 110 and used to limit the horizontal movement of the second elastic stretching rod 430. The second elastic member 440 is located in the second stretching rod limiting guide groove 143, and the two ends of the second elastic member 440 are respectively fixed to the bottom of the second stretching rod limiting guide groove 143 and the corresponding end of the second elastic stretching rod 430 and are in a stretched state. In this specific embodiment, the second elastic member 440 is a spring; a rectangular mounting recess for mounting a linkage guide block 450 is provided at one end of the main frame 310 away from the first elastic stretching rod 330 to ensure the horizontality of the linkage guide block 450 and its verticality with the main frame 310 during installation; corresponding horizontal rectangular fixing cavities are provided at the corresponding ends of the second elastic interference rod 420 and the second elastic stretching rod 430 away from the burning acupuncture point 110, and the two ends of the connecting block 410 match the flat rectangular fixing cavities; when assembling the second elastic interference limiting mechanism 400, first, the fixed end of the linkage guide block 450 is passed through the driving slot 421, and then the two ends of the connecting block 410 are respectively inserted and fixed into the corresponding horizontal rectangular fixing cavities on the second elastic interference rod 420 and the second elastic stretching rod 430;

[0043] When the second elastic interference limit mechanism 400 is installed to the chip positioning seat 100, the installation of the first elastic interference limit mechanism 300 is completed first; then one end of the second elastic member 440 is fixed to one end of the second elastic stretching rod 430 located in the second stretching rod limiting guide groove 143, and then the second elastic interference limit mechanism 400 is inserted into the corresponding preset position from the installation groove 141, and the other end of the second elastic member 440 is fixed to the bottom of the second stretching rod limiting guide groove 143, and then the fixed end of the linkage guide block 450 is vertically fixed to the rectangular mounting recess of the main frame 310 away from one end of the first elastic stretching rod 330 by bolts, thus completing the basic installation of the second elastic interference limit mechanism 400. When the chip positioning seat 100 is fixed to the positioning seat mounting groove by screws, the second elastic interference limit mechanism 400 can be prevented from falling out of the chip positioning seat 100.

[0044] In a specific implementation, when the driving docking block 350 is not in contact with the driving rod 220, the fixed end of the linkage guide block 450 is driven by the main frame 310 to move horizontally toward the driving slot 421 to a preset position, so that the first driving inclined surface and the second driving inclined surface are disengaged, that is, the second elastic resistance rod 420 is in contact with the chip and moves horizontally into the programming point 110 without being affected; and in the setting of this specific embodiment, the first elastic resistance rod 320 elastically resists the short side of the programmed chip, and the second elastic resistance rod 420 elastically resists the long side of the programmed chip, that is, after the driving rod 220 is disengaged from the driving docking block 350, the horizontal movement distance of the first elastic resistance rod 320 is greater than the horizontal movement distance of the second elastic resistance rod 420, so as to avoid linkage The driving end of the guide block 450 affects the elastic reset of the second elastic interference rod 420 and thus limits the chip. In a specific implementation, this problem can also be solved by adjusting the inclination angles of the first driving inclined surface and the second driving inclined surface; the second elastic member 440 is in a stretched state and applies a force toward the bottom of the second stretching rod limiting guide groove 143 to the second elastic stretching rod 430. The second elastic stretching rod 430 drives the second elastic interference rod 420, which contacts the chip, to move horizontally into the burning point 110 through the connecting block 410. The second interference rod limiting guide groove 142 allows the second elastic interference rod 420 to slide horizontally relative to the burning point 110 and limits the second elastic interference rod 420 to ensure that the second elastic interference rod 420 remains horizontal during the movement;

[0045] When the driving rod 220 moves downward to drive the driving docking block 350 to move horizontally away from the programming point 110, the driving docking block 350 drives the fixed end of the linkage guide block 450 to move away from the second elastic interference rod 420 through the main frame 310, thereby driving the first driving inclined surface to drive the second driving inclined surface, that is, driving the second elastic interference rod 420 to move horizontally away from the programming point 110. When the driving rod 220 moves downward to the preset position, the end of the second elastic interference rod 420 that is in contact with the chip leaves the inside of the programming point 110. At this time, the second elastic member 440 is further stretched but is within the effective deformation range.

[0046] When the driving rod 220 moves upward, the first elastic member 340 is in a stretched state during the upward movement of the driving rod 220, exerting a force on the first elastic stretching rod 330 toward the bottom of the first stretching rod limiting guide groove 133. The first elastic stretching rod 330 drives the fixed end of the linkage guide block 450 through the main frame 310 to move toward the direction close to the second elastic interference rod 420, so that the first driving inclined surface and the second driving inclined surface are disengaged, that is, the end of the second elastic interference rod 420 that is in contact with the chip moves horizontally into the burning point 110 without being affected. At the same time When the second elastic member 440 is in a stretched state, it applies a force to the second elastic stretching rod 430 toward the bottom of the second stretching rod limiting guide groove 143. The second elastic stretching rod 430 drives the second elastic interference rod 420, which contacts the chip, to move horizontally into the programming point 110 through the connecting block 410. The second interference rod limiting guide groove 142 allows the second elastic interference rod 420 to slide horizontally relative to the programming point 110 and limits the second elastic interference rod 420 to ensure that the second elastic interference rod 420 remains horizontal during movement.

[0047] That is, when the chip transfer head 210 moves downward to place the chip to be burned on the burning hole 110, the second elastic resistance rod 420 leaves the burning hole 110 under the drive of the driving rod 220 through the linkage guide block 450. When the chip transfer head 210 moves upward to reset, the second elastic resistance rod 420 gradually enters the burning hole 110 as the driving rod 220 moves upward until the chip to be burned is elastically resisted into the burning hole 110.

[0048] By setting an indirect linkage structure with the driving rod 220, the elastic limit range is expanded during the process of placing the detected chip on the burning acupoint 110, and the elastic limit range is gradually elastically reduced after the detected chip is placed on the burning acupoint 110, thereby achieving elastic limitation of the two corresponding sides of the detected chip.

[0049] On the basis of the above, if Figure 7 and Figure 8As shown, the drive docking block 350 includes a connecting portion 351 vertically fixed to the upper surface of the main frame 310 and a driving portion 352 fixed to the upper end of the connecting portion 351. The lower end of the drive rod 220 is provided with a matching third and fourth driving inclined surfaces 353 corresponding to the driving portion 352. When the drive rod 220 moves downward, the third and fourth driving inclined surfaces 353 cooperate to drive the driving portion 352 toward the burning acupuncture point 110. The matching inclined surface structure achieves aligned driving, which has a simple structure, good stability, and low cost.

[0050] On the basis of the above, if Figure 7 and Figure 9 As shown, the drive docking block 350 includes a connecting portion 351 vertically fixed to the upper surface of the main frame 310 and a driving portion 352 fixed to the upper end of the connecting portion 351. The driving portion 352 is provided with a freely rotatable driving roller 354. The lower end of the driving rod 220 is provided with a fifth driving inclined surface corresponding to the driving roller 354. When the driving rod 220 moves downward, the fifth driving inclined surface and the driving roller 354 cooperate to drive the driving portion 352 toward the burning acupuncture point 110. The matching inclined surface and roller structure achieves the alignment drive, which has a simple structure, no additional wear, long service life, good stability, and low cost.

[0051] On the basis of the above, if Figures 2 to 5 As shown, the bottoms of the first stretching rod limiting guide groove 133 and the second stretching rod limiting guide groove 143 are both provided with an operation through-hole 120 that penetrates the periphery of the chip positioning seat 100 , so as to facilitate the fixed installation of the first elastic member 340 and the second elastic member 440 .

[0052] On the basis of the above, if Figure 1 As shown, there are multiple positioning seat grooves arranged linearly in parallel, multiple chip positioning seats 100 are arranged in the same direction in multiple linearly arranged positioning seat grooves, and multiple chip transfer heads 210 can be driven by the transfer mechanism to correspond vertically to multiple chip positioning seats 100. At the same time, each chip can be automatically fixed and limited, which is highly efficient.

[0053] On the basis of the above, if Figure 1 As shown, the first elastic abutment and limiting mechanisms 300 on the plurality of chip positioning seats 100 are located on the same side of the chip positioning mechanism, making the structure more compact.
