Description

Technical Field

[0001] This utility model relates to the field of diode processing equipment technology, specifically a dispensing machine for diode processing. Background Technology

[0002] In the field of diode processing, the dispensing process is a crucial step in ensuring product reliability and performance. Dispensing machines precisely control the application position, quality, and curing effect of the adhesive to achieve bonding, fixation, and protection between the diode chip and its frame. A Chinese patent (publication number: CN202321913453.4) discloses a dispensing machine for diode processing, including a processing worktable and dispensing components mounted on the worktable for dispensing. This device dispenses adhesive through a dispensing head.

[0003] In existing dispensing machines, when the dispensing gun is lifted after completing the dispensing action, residual adhesive on the gun head causes fine filaments to form due to the surface tension of the adhesive, resulting in contamination of the workpiece surface. Furthermore, the residual adhesive on the gun head may drip or splash onto the workpiece surface, forming irregular adhesive spots that damage the appearance of the diode. Utility Model Content

[0004] The purpose of this invention is to provide a dispensing machine for diode processing, which solves the problem of residual adhesive at the dispensing gun head by scraping off the adhesive from the dispensing gun head through a semi-circular platform and a crossbar.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is a dispensing machine for diode processing, including a dispensing machine body, a first spring, and a mounting part. The dispensing machine body is provided with a displacement part, and the output end of the displacement part is mounted to the dispensing gun body through the mounting part. A vertical plate is installed at the bottom of the displacement part, and there are two vertical plates. The bottom of the two vertical plates is provided with a sliding groove, and a crossbar is slidably fitted in the two sliding grooves. The ends of the two crossbars are provided with a semi-circular frustum. There are two first springs, and rectangular blocks are installed on both sides of the crossbars. The two ends of the first springs are respectively connected to the outer surfaces of the vertical plates and the rectangular blocks.

[0007] Furthermore, the displacement unit has a linear module, which is located on the top of the dispensing machine body. The output end of the linear module is equipped with a mounting frame, a vertical plate is installed at the bottom of the mounting frame, and a cylinder is installed inside the mounting frame.

[0008] Furthermore, the mounting section has an L-shaped plate and a clamp. The L-shaped plate is mounted on the output end of the cylinder, and the clamp is mounted on the outer surface of the L-shaped plate. The dispensing gun body is mounted on the L-shaped plate via the clamp.

[0009] Furthermore, the semicircular truncated cone has a groove inside, and cleaning cotton is provided on the side of the semicircular truncated cone.

[0010] Furthermore, the semicircular truncated cone has an installation groove that mates with the crossbar, and a through hole is provided at the bottom of the semicircular truncated cone, with a vertical rod slidingly fitted inside the through hole.

[0011] Furthermore, a U-shaped block is installed at the bottom of the semicircular truncated cone, a second spring is connected to the outer surface of the U-shaped block, a vertical rod is connected to the top of the second spring, and a limiting groove that cooperates with the vertical rod is opened at the end of the horizontal rod.

[0012] This utility model has the following beneficial effects:

[0013] This invention uses a semi-circular platform and a crossbar to scrape off the adhesive from the dispensing gun head. As the gun head of the dispensing gun body passes between the two semi-circular platforms, at the moment the gun head moves out from between the two semi-circular platforms, the first spring pushes the rectangular block to drive the vertical plate, causing the semi-circular platforms to quickly move towards the center. The adhesive is then scraped off by two cleaning cotton pads set on the sides of the semi-circular platforms. This allows the device to remove residual adhesive in real time, avoid contamination, ensure that the gun head is in a clean state, prevent adhesive residue on the gun head of the dispensing gun body, and reduce the defect rate caused by fluctuations in adhesive volume.

[0014] This invention uses a vertical rod and a second spring to install a semicircular platform. When the semicircular platform needs cleaning or replacement after prolonged use, the end of the vertical rod moves out of the limiting groove to release the limiting effect on the semicircular platform, allowing for cleaning or replacement. During installation, the second spring pushes the vertical rod along the cleaning cotton into the limiting groove to limit the semicircular platform, thus completing the installation. This increases the practicality of the device and facilitates cleaning of the semicircular platform.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides a technical solution: a dispensing machine for diode processing, including a dispensing machine body 1, a first spring 7, and a mounting part 3. The mounting part 3 has an L-shaped plate 301 and a clamp 302. The L-shaped plate 301 is mounted on the output end of a cylinder 203, and the clamp 302 is mounted on the outer surface of the L-shaped plate 301. The dispensing gun body 101 is mounted on the L-shaped plate 301 via the clamp 302. When installing the dispensing gun body 101, the clamp 302 facilitates the mounting of the dispensing gun body 101 onto the L-shaped plate 301. The dispensing machine body 1 is provided with a displacement part 2, which has a linear module 201. The linear module 201 is located on the top of the dispensing machine body 1. The output end of the linear module 201 is equipped with a mounting frame 202. A vertical plate 4 is installed at the bottom of the mounting frame 202. A cylinder 203 is installed inside the mounting frame 202. By activating the linear module 201, the vertical plate 4 can be driven to move the dispensing gun body 101 laterally. Activating the cylinder 203 can drive the dispensing gun body 101 to move vertically. The output end of the displacement part 2 is mounted to the dispensing gun body 101 via the mounting part 3. A vertical plate 4 is installed at the bottom of the displacement part 2. There are two vertical plates 4. The bottom of each vertical plate 4 is provided with a sliding groove 401. A crossbar 5 is slidably fitted in each of the two sliding grooves 401. A semi-circular platform 8 is provided at the end of each of the two crossbars 5. The semi-circular platform 8 has a groove 801 inside. The cross-sectional projection of the groove 801 is an inverted trapezoid. During the movement of the nozzle of the dispensing gun body 101 towards the bottom, the semi-circular platform of the groove 801, with its inverted trapezoidal cross-sectional projection, allows the nozzle to easily abut against the semi-circular platform 8, causing the semi-circular platform 8 to move to both sides. A cleaning cotton 802 is provided on the side of the platform 8, which can be used to clean the adhesive. There are two first springs 7. Rectangular blocks 6 are installed on both sides of the crossbar 5. The two ends of the first springs 7 are respectively connected to the outer surfaces of the vertical plate 4 and the rectangular blocks 6. When the dispensing machine body 1 is in use, the displacement part 2 moves the dispensing gun body 101, causing the nozzle of the dispensing gun body 101 to touch the groove 8 as it moves towards the bottom. 01. Since the cross-sectional projection of the groove 801 is an inverted trapezoid, the gun head contacts the groove 801 and squeezes the semi-circular platform 8 on both sides, causing the two semi-circular platforms 8 to move to both sides respectively. This pushes the crossbar 5 to compress the first spring 7 through the rectangular block 6. After the glue gun body 101 finishes dispensing glue to the diode, the displacement part 2 resets the glue gun body 101 and moves the glue gun body 101 to the top. Since the gun head of the glue gun body 101 passes between the two semi-circular platforms 8, at the moment the gun head moves out from between the two semi-circular platforms 8, the first spring 7 pushes the rectangular block 6 to drive the vertical plate 4, causing the semi-circular platforms 8 to quickly move towards the middle and scrape off the glue through the two cleaning cotton 802s set on the sides of the semi-circular platforms 8.

[0023] The semicircular platform 8 has a mounting groove 803 inside that mates with the crossbar 5. A through hole 804 is provided at the bottom of the semicircular platform 8, and a vertical rod 10 is slidably fitted inside the through hole 804. A flange is provided on the side of the end of the vertical rod 10, facilitating the pulling of the vertical rod 10. A U-shaped block 9 is installed at the bottom of the semicircular platform 8, and a second spring 11 is connected to the outer surface of the U-shaped block 9. The top of the second spring 11 is connected to the vertical rod 10. A limiting groove 501 is provided at the end of the crossbar 5 to mate with the vertical rod 10. When the semicircular platform 8 needs cleaning or replacement after prolonged use, the groove is located at the bottom. Pulling the flange on the side of the vertical rod 10 causes the vertical rod 10 to move to the bottom, so that the end of the vertical rod 10 moves out of the limiting groove 501 and out of the semi-circular platform 8 through the through hole 804. At this time, the second spring 11 is compressed, and the limiting of the semi-circular platform 8 is released. The semi-circular platform 8 can then be cleaned or replaced. After that, the semi-circular platform 8 is put on the horizontal bar 5, so that the end of the horizontal bar 5 enters the mounting groove 803. Then, the flange is released and the second spring 11 pushes the vertical rod 10 through the through hole 804 into the limiting groove 501 to limit the semi-circular platform 8, thus completing the installation of the semi-circular platform 8.
