In this semiconductor component dispensing device, the adjusting screw can be rotated to adjust the height of the glue nozzle. In this process, personnel can manually change the shape of the shaping hose, so that the end of the shaping hose connected to the glue delivery pipeline is still in the initial position, thereby avoiding the change of the position of the glue delivery pipeline due to the rotation of the glue delivery nozzle, so as to ensure the connection stability between the glue delivery nozzle and the glue delivery pipeline, which is suitable for being widely promoted and used.

[0004] The above patent has the function of ensuring a stable connection between the glue outlet nozzle and the glue delivery pipe.

[0013] According to the above technical solution, a circular hole is opened on the C-shaped plate, and the circular hole is adapted to a side of the door-shaped rod close to the C-shaped plate, pushing the door-shaped rod to move toward the placement table. The door-shaped rod passes through the circular hole of the C-shaped plate during the movement, so that the door-shaped rod locks the movement of the C-shaped plate.

[0014] The present invention provides a glue dispensing device for semiconductor device production, which has the following beneficial effects:

[0015] (1) In the dispensing device for semiconductor device production, the contact block and the top of the limit plate are in contact, so that the movement of the placement table is restricted. The movement of the contact block is restricted by the limit plate, so that the placement table is immediately limited when it reaches the specified position, without waiting for manual confirmation or adjustment by personnel, thereby reducing the need for manual intervention. The convex rod and the inclined plate are held, so that the contact block is restricted from resetting downward. Only through standardized operation can the placement table be released from the restriction and move, effectively preventing accidental movement during the dispensing process that causes the dispensing position to deviate from the predetermined point, thereby ensuring the accuracy of dispensing.

[0016] (2) In the glue dispensing device for semiconductor device production, the corrugation 1 of the pressure plate contacts the top of the device during movement, and the device moved to the specified position is automatically pressed by the pressure plate, which effectively improves the stability of the device during the glue dispensing process. The intermittent vibration is then transmitted to the pressure plate, making the corrugation 1 and the device fit more closely when in contact. The deformed spring No. 3 recovers and drives the L-shaped rod to move upward. When the placement table is pulled out, the pressure plate is automatically separated from the device, which reduces the workload of the personnel and maintains the continuity of the operation. At the same time, the arc piece and the inclined surface No. 3 are in contact without collision, which improves the accurate release of vibration.

[0017] (3) In the glue dispensing device used in the production of semiconductor devices, the seal imposed by the sealing gasket on the hollow frame is released, and the glue output by the glue dispensing mechanism drips onto the device through the hollow frame. The sealing gasket automatically opens when the device moves into position, ensuring that the glue released by the glue dispensing mechanism can drip onto the correct position of the device, thereby improving the quality and consistency of glue dispensing. The door-shaped rod passes through the circular hole of the C-shaped plate, so that the door-shaped rod locks the movement of the C-shaped plate. Through the contact between the door-shaped rod and the circular hole, the personnel can actively lock the C-shaped plate when performing maintenance and adjustment, effectively improving the safety of the personnel's hands when working under the glue dispensing mechanism.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-Figure 8, one embodiment of the present invention is: a glue dispensing device for semiconductor device production, including a base 1, a control console 2 is arranged on the surface of the base 1, a support frame 3 is fixedly installed on the top of the base 1, a glue dispensing mechanism 4 is fixedly penetrated on the top of the support frame 3, a slide rail 5 is fixedly installed on the top of the base 1, and a placement table 6 is slidably installed on the top of the slide rail 5, the control console 2 includes an output module and a control module, the output module is electrically connected to the control end of the glue dispensing mechanism 4, the glue dispensing mechanism 4 is provided with glue inside, and also includes a locking device; wherein the locking device includes a loading plate 7, a contact block 8, a No. 1 spring 9, a limit plate 10, a T-shaped block 11, a convex rod 12, a No. 2 spring 13 and an inclined plate 14, the loading plate 7 is fixed It is installed at the bottom of the placement table 6, the contact block 8 is slidably installed on the inner wall of the loading plate 7, the No. 1 spring 9 is arranged between the contact block 8 and the loading plate 7, the limit plate 10 is fixedly installed on the top of the base 1, the T-block 11 slides through the side of the loading plate 7 away from the limit plate 10, the convex rod 12 is fixedly installed on the side of the T-block 11 away from the loading plate 7, the No. 2 spring 13 is arranged between the convex rod 12 and the loading plate 7, the inclined plate 14 is fixedly installed on the side of the loading plate 7 away from the slide rail 5, and the movement of the contact block 8 is limited by the limit plate 10, so that the placement table 6 is immediately limited when it reaches the specified position, without waiting for manual confirmation or adjustment by personnel, reducing the operating steps of personnel, thereby improving production efficiency.

[0029] A sloped surface 1 is provided on one side of the contact block 8 close to the limit plate 10, and an arcuate surface 1 is provided on one side of the limit plate 10 close to the contact block 8. By providing the sloped surface 1 and the arcuate surface 1, it is ensured that when the contact block 8 and the limit plate 10 are in contact, the resistance applied by the arcuate surface 1 by the limit plate 10 can stably drive the contact block 8 to move upward.

[0030] The T-shaped block 11 has two inclined surfaces on one side close to the contact block 8, and the contact block 8 has two arc surfaces on one side close to the T-shaped block 11. The restriction on the placement table 6 can be released and moved only by holding the convex rod 12 and the inclined plate 14 in a standardized manner, which effectively prevents accidental touching during the dispensing process from causing the dispensing position to deviate from the predetermined point.

[0031] When the present embodiment is working, the device is placed on the top of the placement table 6, and the convex rod 12 is pushed to move toward the loading plate 7. The movement of the convex rod 12 drives the loading plate 7 to move toward the limit plate 10. The movement of the loading plate 7 drives the inclined plate 14 to move toward the limit plate 10. At the same time, the movement of the loading plate 7 drives the placement table 6 to move toward the limit plate 10. The movement of the placement table 6 drives the device to move toward the limit plate 10. The movement of the loading plate 7 drives the contact block 8 to move toward the limit plate 10. The inclined surface 1 of the contact block 8 contacts the arc surface 1 of the limit plate 10 during the movement. The movement of the inclined surface 1 is subject to the resistance exerted by the arc surface 1. The contact block 8 moves upward under the influence of the resistance. The contact block 8 squeezes during the movement. The first spring 9 is pressed and deformed. When the inclined surface 1 continues to move and separates from the arc surface 1, the resistance exerted by the arc surface on the inclined surface 1 gradually decreases, so that the deformed first spring 9 recovers under the action of its own elasticity. The recovery of the first spring 9 drives the contact block 8 to move downward. The bottom of the contact block 8 contacts the top of the limit plate 10 during the movement, so that the movement of the placement table 6 away from the dispensing mechanism 4 is restricted. At the same time, when the placement table 6 moves to the bottom of the dispensing mechanism 4, it is restricted by the slide rail 5 and stops moving. The movement of the contact block 8 is limited by the limit plate 10, so that the placement table 6 is immediately limited when it reaches the specified position, without waiting for manual confirmation or adjustment by personnel. The production efficiency is improved. The personnel manually start the control module of the control console 2, so that the output module of the control console 2 starts the dispensing mechanism 4 to perform the dispensing work. After the work is completed, the dispensing mechanism 4 is closed, and the convex rod 12 is pushed to move in the direction of the limit plate 10. The convex rod 12 squeezes the second spring 13 during the movement. The second spring 13 is squeezed and deformed. At the same time, the movement of the convex rod 12 drives the T-shaped block 11 to move in the direction of the contact block 8. The inclined surface 2 of the T-shaped block 11 contacts the arc surface 2 of the contact block 8 during the movement. The inclined surface 2 applies an upward thrust to the arc surface 2 during the movement. The contact block 8 moves upward under the action of the thrust. The contact block 8 squeezes the first spring 9 when moving. At the same time, the contact block 8 During the movement, the side in contact with the limit plate 10 is separated, so that the restriction on the loading plate 7 moving away from the dispensing mechanism 4 is released, and the convex rod 12 and the inclined plate 14 are held, so that the contact block 8 is restricted from resetting downward, and the inclined plate 14 is pulled to move in the direction away from the limit plate 10. The movement of the inclined plate 14 drives the loading plate 7 to move away from the limit plate 10. The movement of the loading plate 7 drives the placement table 6 to move away from the limit plate 10. The movement of the placement table 6 drives the device to move away from the dispensing mechanism 4. Only by holding the convex rod 12 and the inclined plate 14 in a standardized operation can the restriction on the placement table 6 be released and moved, effectively preventing accidental movement from causing the dispensing position to deviate from the predetermined point.

[0032] See also Figure 1-Figure 8On the basis of the above embodiment, another embodiment of the present invention further includes a stabilizing device and a safety device; the stabilizing device includes a hollow plate 151, a cylinder 152, an L-shaped rod 153, a No. 3 spring 154, a round rod 155, a pressure plate 156, an arc-shaped sheet 157 and a blocking plate 158, the hollow plate 151 is fixedly mounted on the top of the base 1, the cylinder 152 is fixedly mounted on the top of the inner wall of the hollow plate 151, the L-shaped rod 153 slides through the bottom of the cylinder 152, the No. 3 spring 154 is arranged between the L-shaped rod 153 and the cylinder 152, and the round rod 155 is fixedly mounted on the circumferential surface of the L-shaped rod 153, The pressure plate 156 is fixedly mounted on one end of the L-shaped rod 153 close to the dispensing mechanism 4, the arc-shaped sheet 157 is fixedly mounted on the circumferential surface of the L-shaped rod 153, the blocking plate 158 is fixedly mounted on the inner wall of the hollow plate 151, and the end of the L-shaped rod 153 close to the pressure plate 156 slides through the inner and outer walls of the hollow plate 151, and the round rod 155 slides through the inner and outer walls of the hollow plate 151. By arranging a No. 3 spring 154 between the L-shaped rod 153 and the cylinder 152, the elasticity of the No. 3 spring 154 itself is used to ensure that the L-shaped rod 153 can be smoothly reset to the initial position under the action of the elastic force after moving, so as to prepare for the next work.

[0033] A corrugation 1 is provided at the bottom of the pressing plate 156. The arc-shaped sheet 157 itself is elastic and can automatically contact the device moved to the specified position through the pressing plate 156 to position the device before dispensing, and then transmit the vibration to the pressing plate 156 to ensure that the corrugation 1 and the device are stably fitted.

[0034] An arc surface three is provided at one end of the arc piece 157 close to the blocking plate 158, and an inclined surface three is provided at the bottom of the blocking plate 158. When the placement table 6 is pulled out, the pressure plate 156 is automatically separated from the device, thereby improving the pulling efficiency. At the same time, the arc piece 157 and the inclined surface three are in contact without triggering a collision, thereby ensuring the accuracy of the vibration.

[0035] The safety device includes a flat plate 161, a hollow frame 162, a C-shaped plate 163, a spring 164, a connecting frame 165, a rotating plate 166, two sealing gaskets 167 and a door-shaped rod 168. The flat plate 161 is fixedly mounted on a side of the hollow plate 151 close to the pressure plate 156, the hollow frame 162 is fixedly penetrated through the top of the flat plate 161, the C-shaped plate 163 slides through the top of the flat plate 161, the spring 164 is arranged between the C-shaped plate 163 and the flat plate 161, the connecting frame 165 is fixedly mounted on the bottom of the flat plate 161, and the rotating plate 166 is rotatably mounted on the inner wall of the connecting frame 165. A sealing gasket 167 is fixedly installed on a side of the rotating plate 166 close to the hollow frame 162, and a door-shaped rod 168 slides through a side of the flat plate 161 away from the placement table 6. One end of the C-shaped plate 163 away from the hollow frame 162 contacts the circumferential surface of the L-shaped rod 153, and the other end of the C-shaped plate 163 contacts the bottom of the rotating plate 166. The sealing gasket 167 contacts the bottom of the hollow frame 162. The sealing gasket 167 can only be opened by moving the device into place, ensuring that the glue released by the dispensing mechanism 4 can drip on the device when the device is in the correct position, thereby improving the quality and consistency of dispensing.

[0036] A circular hole is provided on the C-shaped plate 163, which is matched with a side of the door-shaped rod 168 close to the C-shaped plate 163. Through the contact between the door-shaped rod 168 and the circular hole, the personnel can actively lock the C-shaped plate 163 when performing maintenance and adjustment, thereby providing safety insurance for the personnel's hands when working under the dispensing mechanism 4.

[0037] When the embodiment is working, the inclined plate 14 moves toward the limit plate 10 and contacts the top of the round rod 155. The movement of the inclined plate 14 applies downward pressure to the round rod 155. The round rod 155 moves downward under the pressure. The movement of the round rod 155 drives the L-shaped rod 153 to move downward. The L-shaped rod 153 stretches the No. 3 spring 154 when moving. The No. 3 spring 154 is stretched and deformed. The movement of the L-shaped rod 153 drives the pressure plate 156 to move downward. The corrugation of the pressure plate 156 contacts the top of the device during the movement. The arc piece 157 is in contact with the upper part of the arc surface 158, and the L-shaped rod 153 moves to drive the arc piece 157 to move downward. The arc surface 3 of the arc piece 157 contacts the top of the blocking plate 158 during the movement. The arc surface 3 is resisted by the blocking plate 158. The arc piece 157 continues to move and deforms under the influence of the resistance. When the arc surface 3 and the side in contact with the blocking plate 158 are separated, the deformed arc piece 157 recovers under the action of its own elasticity, so that the arc surface 3 and the blocking plate 158 intermittently collide to generate vibration, and the pressure plate 156 automatically The device moves to the designated position and contacts the device to ensure the stability of the device during the dispensing process, and then transmits the vibration to the pressure plate 156 to ensure that the corrugation 1 and the device are stably fitted. After the dispensing is completed, the inclined plate 14 is reset. During the resetting process, the pressure exerted by the inclined plate 14 on the round rod 155 is gradually reduced, so that the deformed No. 3 spring 154 is restored to drive the L-shaped rod 153 to move upward. The movement of the L-shaped rod 153 drives the pressure plate 156 to move upward. The side of the corrugation 1 that contacts the device is separated during the movement. At the same time, the L-shaped rod 15 3. The movement drives the arc piece 157 to move upward. The arc piece 157 contacts the inclined surface 3 of the blocking plate 158 during the movement. The arc piece 157 continues to move and is deformed by the resistance exerted by the inclined surface 3. When the arc piece 157 and the side in contact with the inclined surface 3 are separated, the deformed arc piece 157 recovers under the action of its own elasticity. When the placement table 6 is pulled out, the pressing plate 156 is automatically separated from the device, which reduces the workload of the personnel. At the same time, the contact between the arc piece 157 and the inclined surface 3 does not trigger a collision, thereby improving the accuracy of the work.

[0038] When the L-shaped rod 153 moves downward, the thrust applied to the C-shaped plate 163 is gradually reduced, so that the stretched spring sheet 164 recovers under the action of its own elasticity, and the recovery of the spring sheet 164 drives the C-shaped plate 163 to move downward. During the movement, the end of the C-shaped plate 163 close to the hollow frame 162 reduces the supporting force applied to the rotating plate 166, so that the rotating plate 166 rotates in the direction away from the hollow frame 162 under the action of its own gravity. The rotation of the rotating plate 166 drives the sealing gasket 167 to move in the direction away from the hollow frame 162. During the movement, the sealing gasket 167 is separated from the side in contact with the bottom of the hollow frame 162, so that the blockage applied by the sealing gasket 167 to the bottom of the hollow frame 162 is released, and the glue output by the dispensing mechanism 4 drips onto the device through the hollow frame 162, and the sealing gasket is opened when the device moves into place. Piece 167 ensures that the glue released by the dispensing mechanism 4 can drip onto the device when the device is in the correct position, thereby improving the quality and consistency of dispensing. In the initial state, when it is necessary to maintain the seal of the sealing gasket 167 on the bottom of the hollow frame 162, the door-shaped rod 168 is pushed to move toward the placement table 6, and the door-shaped rod 168 passes through the circular hole of the C-shaped plate 163 during the movement, so that the door-shaped rod 168 locks the movement of the C-shaped plate 163. After the C-shaped plate 163 is locked, the rotating plate 166 is stably supported by the support force applied by the C-shaped plate 163, so that the sealing gasket 167 is stably in contact with the bottom of the hollow frame 162 for sealing. Through the contact between the door-shaped rod 168 and the circular hole, the personnel can actively lock the C-shaped plate 163 when performing maintenance and adjustment, effectively improving the safety of the personnel's hands when working under the dispensing mechanism 4.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
