Description

Technical Field

[0001] This utility model relates to the field of semiconductor testing dotting device technology, and in particular to a glue dotting device. Background Technology

[0002] In semiconductor chip testing, it is necessary to mark, identify, and remove defective chips detected in the chip inspection process, allowing qualified chips to proceed to the next process to prevent defective chips from affecting subsequent operations. Typically, a dotting device is used to mark defective chips. Current dotting devices are disposable, meaning the ink fountain cannot be reused. Once the glue is used up, the ink fountain must be removed and discarded, replaced with a new one, and readjusted before dotting can be performed again. This traditional disposable dotting device has a low ink fountain replacement and readjustment rate, and a single ink fountain replacement takes a long time. Furthermore, existing dotting devices rely on a driver to control the extension and retraction of the needle core for dotting, which can easily lead to uneven dot size, poor dotting effect, and hinders accurate subsequent identification, resulting in low reliability. Utility Model Content

[0003] The main purpose of this invention is to propose a glue-dispensing dotting device, which aims to solve the technical problems of long ink fountain replacement time, poor dotting effect, and poor reliability of existing dotting devices.

[0004] To achieve the above objectives, this utility model proposes a glue dispensing and dotting device, comprising:

[0005] A support base extending along a first direction, with one side of the support base being the mounting side;

[0006] The glue-filling ink fountain includes a mandrel and an ink tank. The ink tank is installed on the installation side, and a receiving cavity for holding glue is formed inside the ink tank. The mandrel passes through the receiving cavity, and the two ends of the mandrel along the first direction extend from the two ends of the ink tank along the first direction, respectively.

[0007] A drive mechanism is mounted on the mounting side and located at one end of the ink tank. The drive mechanism includes a drive component and a transmission shaft. One end of the transmission shaft is connected to the spindle. The drive component is used to drive the transmission shaft to move along the first direction and drive the spindle to move relative to the ink tank along the first direction. The ink tank has an ink inlet communicating with the receiving cavity at one end near the drive mechanism.

[0008] A limiting member is provided on the mounting side and is movable relative to the support base in the first direction. The limiting member is used to abut against the end of the drive shaft away from the spindle.

[0009] In one embodiment, the mounting side is provided with a mounting groove extending along the first direction, the ink tank is mounted in the mounting groove, and the two ends of the spindle extend out of the mounting groove along the first direction.

[0010] In one embodiment, the mounting side is provided with two mounting blocks, which are spaced apart along the first direction and form a mounting groove between them. Each of the two mounting blocks is provided with a snap-fit, and the ink tank is snapped into the corresponding snap-fit ​​at both ends along the first direction.

[0011] In one embodiment, a connector is provided at one end of the ink tank near the drive mechanism, and the ink injection port is formed between the connector and the ink tank. The connector is engaged with the slot of the corresponding mounting block. A snap-fit ​​post is provided at one end of the ink tank away from the drive mechanism, and the snap-fit ​​post is engaged with the slot of another mounting block. The two ends of the mandrel along the first direction pass through the connector and the snap-fit ​​post, respectively.

[0012] In one embodiment, a mounting frame is provided on the mounting side, and the mounting frame and the support base form a mounting space; the driving component is a coil sleeved outside the transmission shaft, the driving component is installed in the mounting space, and the two ends of the transmission shaft along the first direction protrude outside the mounting frame; when the coil is energized, it drives the transmission shaft to move along the first direction;

[0013] The limiting component includes a baffle and a connecting post connected to each other. The connecting post is connected to the side of the mounting frame away from the ink tank, and the connecting post can move relative to the mounting frame in the first direction. The end of the drive shaft away from the spindle abuts against the baffle when the coil is de-energized.

[0014] In one embodiment, the connecting post is a stud, and the mounting frame is provided with a threaded hole into which the stud extends and engages with the stud.

[0015] In one embodiment, the mounting frame is provided with a plurality of heat dissipation holes that communicate with the mounting space at intervals.

[0016] In one embodiment, a stop block is provided at one end of the drive shaft near the baffle, the stop block being used to abut against the coil when the coil drives the drive shaft to move in the first direction.

[0017] In one embodiment, the drive shaft is fitted with an elastic element, and the elastic element abuts between the coil and the stop block.

[0018] In one embodiment, the stop block is provided with a guide post extending toward the support base on the side facing the support base, and a guide groove is provided on the support base corresponding to the position of the guide post. The guide post extends into the guide groove and slides along the guide groove when the drive shaft moves in the first direction.

[0019] This utility model discloses a glue-dispensing dotting device. By mounting the glue dispensing ink fountain on a support base, the stability of the ink tank during operation is improved, preventing the glue in the ink tank from spilling out. In use, a drive unit drives the transmission shaft to move up and down, thereby moving the mandrel up and down. The mandrel passes through the receiving cavity, and the glue in the ink tank adheres to the mandrel and soaks into its bottom end, thus dispensing dots through the bottom of the mandrel. Furthermore, a glue dispensing port communicating with the receiving cavity is provided at the top of the ink tank, facilitating quick refilling of glue after use, making operation simpler and faster, avoiding the need to replace the entire ink fountain after the glue is used up, as is the case with traditional dotting devices. In addition, a limiter is provided at the top of the drive unit, and the top of the transmission shaft abuts against the limiter, better limiting the up and down travel of the transmission shaft, thereby further controlling the travel of the mandrel. This ensures that the mandrel travels a consistent distance each time, guaranteeing consistent dotting size and force, resulting in good dotting effect, improved accuracy of subsequent recognition, and high reliability.

[0030] This utility model proposes a glue dispensing dotting device 100.

[0031] Please see Figures 1-3In one embodiment of this utility model, the glue dispensing device 100 includes a support base 1, a glue dispensing ink fountain 2, a driving mechanism 3, and a limiting member 4; the support base 1 extends along a first direction, and one side of the support base 1 is the mounting side 11; the glue dispensing ink fountain 2 includes a spindle 21 and an ink tank 22, the ink tank 22 is mounted on the mounting side 11, and a receiving cavity for dispensing glue is formed inside the ink tank 22, the spindle 21 passes through the receiving cavity, and both ends of the spindle 21 along the first direction extend from both ends of the ink tank 22 along the first direction; the driving mechanism 3 is mounted on the mounting side 11, and the driving mechanism 4 limits the dispensing device 1 ...00. The driving mechanism 3 is located at one end of the ink tank 22. The driving mechanism 3 includes a driving member 31 and a transmission shaft 32. One end of the transmission shaft 32 is connected to the spindle 21. The driving member 31 is used to drive the transmission shaft 32 to move along the first direction and drive the spindle 21 to move relative to the ink tank 22 along the first direction. The ink tank 22 has an injection port 221 that communicates with the accommodating cavity at one end near the driving mechanism 3. The limiting member 4 is located on the mounting side 11 and can move relative to the support base 1 along the first direction. The limiting member 4 is used to abut against the end of the transmission shaft 32 away from the spindle 21.

[0032] The glue dispensing applicator 100 of this utility model improves the stability of the ink tank 22 during operation by mounting the glue dispensing ink fountain 2 on the support base 1, preventing the glue in the ink tank 22 from spilling out. In use, the drive shaft 32 is driven up and down by the drive component 31, thereby driving the spindle 21 to move up and down. The spindle 21 passes through the receiving cavity, and the glue in the ink tank 22 adheres to the spindle 21 and penetrates to the bottom end of the spindle 21, thus dispensing through the bottom end of the spindle 21. Furthermore, a glue dispensing port 22 communicating with the receiving cavity is provided at the top of the ink tank 22. 1. It allows for quick and easy refilling of the ink tank 22 after the glue in the tank is used up, making operation simpler and faster, and avoiding the problem of having to replace the entire ink fountain when the glue in traditional dotting devices runs out; In addition, a limiting component 4 is provided at the top of the drive component 31, and the top of the drive shaft 32 can abut against the limiting component 4, which can better limit the up and down movement of the drive shaft 32, thereby further controlling the running stroke of the spindle 21, so that the movement distance of the spindle 21 is consistent each time, thus ensuring that the dot size and force are consistent, thereby improving the accuracy of subsequent recognition and making it more reliable.

[0033] Specifically, in this embodiment, the spindle 21 and the drive shaft 32 are coaxially arranged.

[0034] In one embodiment, the mounting side 11 is provided with a mounting groove 14 extending in a first direction, the ink tank 22 is mounted in the mounting groove 14, and the spindle 21 extends out of the mounting groove 14 at both ends in the first direction.

[0035] Understandably, by fixing the ink tank 22 with the mounting groove 14 on the support base 1, the stability of the ink tank 22 during operation can be ensured, reducing displacement of the ink tank 22 due to vibration or external force, thereby improving the accuracy of dotting operations; and the mounting groove 14 makes the installation and removal of the ink tank 22 simpler and faster. The top and bottom ends of the spindle 21 pass through the top and bottom walls of the mounting groove 14 respectively and protrude outside the mounting groove 14, so as to connect the drive shaft 32 and perform dotting operations respectively, and also ensure the consistency of the movement direction of the spindle 21.

[0036] In one embodiment, the mounting side 11 is provided with two mounting blocks 13, which are spaced apart along a first direction and form a mounting groove 14 between the two mounting blocks 13. Each of the two mounting blocks 13 is provided with a snap-fit ​​131, and the two ends of the ink tank 22 along the first direction are respectively snapped into the corresponding snap-fit ​​131.

[0037] Understandably, by setting two mounting blocks 13 with snap-fit ​​slots 131 on them to engage the top and bottom of the ink tank 22, it is ensured that the ink tank 22 will not shift due to vibration or external force during operation, thus guaranteeing the accuracy of the dot-printing operation. The snap-fit ​​installation method for the ink tank 22 makes the assembly process simpler and faster, requiring no additional tools or fasteners to install or remove the ink tank 22.

[0038] Furthermore, both mounting blocks 13 are integrally formed with the support base 1.

[0039] In one embodiment, a connector 222 is provided at one end of the ink tank 22 near the drive mechanism 3, and an injection port 221 is formed between the connector 222 and the ink tank 22. The connector 222 is engaged with the slot 131 of the corresponding mounting block 13. A locking post 223 is provided at one end of the ink tank 22 away from the drive mechanism 3. The locking post 223 is engaged with the slot 131 of another mounting block 13. The two ends of the spindle 21 along the first direction pass through the connector 222 and the locking post 223 respectively.

[0040] Understandably, by setting a connector 222 on the top of the ink tank 22 and forming a glue inlet 221 between the connector 222 and the ink tank 22, the operation of adding glue into the ink tank 22 is made simpler. After the glue is used up, it is not necessary to disassemble the entire ink tank 22 to add glue, reducing the repeated adjustment process due to replacing the ink tank 22 and further reducing manpower consumption. The design of using the connector 222 and the snap-fit ​​post 223 to fix the top and bottom of the ink tank 22 makes the ink tank 22 more stable.

[0041] In one embodiment, the mounting side 11 is provided with a mounting frame 12, and the mounting frame 12 and the support base 1 form a mounting space; the driving member 31 is a coil sleeved outside the drive shaft 32, and the driving member 31 is installed in the mounting space, with both ends of the drive shaft 32 along the first direction exposed outside the mounting frame 12; when the coil is energized, it drives the drive shaft 32 to move along the first direction; the limiting member 4 includes a baffle 42 and a connecting post 41 connected to each other, the connecting post 41 is connected to the side of the mounting frame 12 away from the ink tank 22, and the connecting post 41 can move relative to the mounting frame 12 along the first direction; the end of the drive shaft 32 away from the spindle 21 abuts against the baffle 42 when the coil is de-energized.

[0042] Understandably, the driving component 31 is a coil. When the coil is energized, it generates electromagnetic force to drive the transmission shaft 32 downward to complete the dotting operation. When the coil is de-energized, the position of the transmission shaft 32 returns to its original position. Since the driving component 31 is located within the mounting frame 12, it effectively maintains relative stability, thus facilitating precise dotting by driving the mandrel 21 via the transmission shaft 32. Furthermore, the limiting component 4 is also located on the mounting frame 12, and the baffle 42 restricts the movement range of the transmission shaft 32 to ensure that the movement distance of the transmission shaft 32 is consistent each time, which helps to accurately control the dotting size and ensures dotting consistency. In addition, the connecting post 41 can move up and down relative to the mounting frame 12, thereby adjusting the position of the baffle 42 and precisely controlling the up and down movement stroke of the transmission shaft 32. This facilitates the control of the mandrel 21's dotting operation, allowing the mandrel 21 to produce appropriately sized glue dots with greater flexibility.

[0043] In one embodiment, the connecting post 41 is a stud, and the mounting frame 12 is provided with a threaded hole for the stud to extend into and engage with the stud thread.

[0044] Understandably, the connecting post 41 is threadedly connected to the mounting frame 12, allowing for precise adjustment of the height of the baffle 42 as needed. The position of the baffle 42 can be finely adjusted by rotating the stud to accommodate different marking requirements, ensuring optimal movement of the drive shaft 32. Furthermore, the threaded connection between the stud and the mounting frame 12 simplifies and speeds up the assembly process of the limiting component 4.

[0045] In one embodiment, the mounting frame 12 is provided with a plurality of heat dissipation holes 121 that communicate with the mounting space at intervals.

[0046] In this embodiment, the heat dissipation hole 121 can effectively increase the air circulation between the installation space and the outside, help to dissipate the heat generated by the drive component 31 when it is working in the installation space, which helps to reduce the operating temperature of the drive component 31, prevent overheating, thereby extending its service life and maintaining the stability of the operation of the drive component 31.

[0047] In one embodiment, a stop block 321 is provided at one end of the drive shaft 32 near the baffle 42. The stop block 321 is used to abut against the coil when the coil drives the drive shaft 32 to move in a first direction.

[0048] Understandably, the design of the stop 321 ensures that the drive shaft 32 will not exceed the predetermined maximum stroke when it moves downward. Since the stop 321 can abut against the drive member 31 when it moves downward, it will prevent the drive shaft 32 from continuing to move downward, thereby effectively preventing the chip from being damaged by the excessive downward movement of the spindle 21 driven by the drive shaft 32, resulting in better reliability.

[0049] In one embodiment, an elastic element 33 is sleeved on the drive shaft 32, and the elastic element 33 abuts between the coil and the stop block 321.

[0050] Understandably, when the coil is energized, it generates an electromagnetic force that drives the drive shaft 32 downward to complete the dotting operation. When the coil is de-energized, the magnetic force disappears. At this time, the elastic element 33 provides an upward elastic force to help the drive shaft 32 quickly return to its initial position, achieving automatic reset without the need for an additional mechanical reset device. Power is only required to the coil when the dotting operation is needed, making it more energy-efficient.

[0051] In one embodiment, the stop block 321 is provided with a guide post 322 extending toward the support base 1 on the side facing the support base 1. A guide groove 15 is provided on the support base 1 at the position corresponding to the guide post 322. The guide post 322 extends into the guide groove 15 and slides along the guide groove 15 when the drive shaft 32 moves in the first direction.

[0052] In this embodiment, the design of the guide post 322 and the guide groove 15 provides an additional guiding mechanism for the drive shaft 32, ensuring that it can only move in the vertical direction. This helps reduce lateral offset or swaying of the drive shaft 32, thereby improving the accuracy of the dotting action. Furthermore, the presence of the limiting member 4 prevents the drive shaft 32 from popping upwards under the elastic force of the elastic member 33, ensuring that the movement distance of the drive shaft 32 and the spindle 21 is consistent each time, thus ensuring consistent dotting and better reliability.

[0053] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
