Description

Technical Field

[0001] The utility model relates to the technical field of chip mounter equipment, in particular to a glue dispensing rod structure of a chip mounter. Background Art

[0002] The chip mounter plays an extremely important role in electronic manufacturing. It is responsible for placing various electronic components on the circuit board accurately and quickly. The dispensing rod, as a key part of the chip mounter, will move to the position where the component needs to be pasted when the chip mounter starts working. Then, the control mechanism will start to transport the glue from the reservoir to the inside of the rod body and apply it to the component through the glue outlet. Then, the chip mounter will quickly paste the component to the specified position of the circuit board, completing the entire pasting process.

[0003] A glue dispensing rod structure of a chip placement machine disclosed in the Chinese utility model patent application disclosure CN220674028U can be used to complete several glue dispensings at the glue head. When a large amount of residual glue is accumulated at the glue dispensing location, the ring body is moved to the glue dispensing location at the bottom of the glue head, and the driving mechanism is started to rotate the scraper on the surface of the glue dispensing location to scrape off the excess glue and store it in the storage box. The frequency of glue scraping at the glue head can be set according to actual conditions, so that an automatic cleaning structure can be added at the glue dispensing location to process the excess glue. However, long-term use of the glue dispensing rod will cause a large amount of glue to adhere to the rod body. At this time, the glue cannot be cleaned in time, which will cause the glue dispensing head to be blocked. At the same time, when the glue is cleaned, the glue dispensing rod may be damaged, thereby affecting the stability of the subsequent use of the chip placement machine. Utility Model Content

[0004] The purpose of the utility model is to provide a dispensing rod structure of a placement machine to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dispensing rod structure of a placement machine, including a dispensing head, a fixed plate is fixedly connected to the middle position of the bottom end of the dispensing head, a lifting mechanism is arranged inside both sides of the fixed plate, a clamping mechanism is installed at the bottom end of the lifting mechanism, limiting mechanisms are arranged at the bottom ends of both sides of the dispensing head, and a dispensing mechanism is arranged in the middle position of the bottom end of the dispensing head.

[0006] Preferably, a transmission tube is fixedly connected to the middle position of the top of the dispensing head, and the external glue can be input into the interior of the dispensing head through the transmission tube.

[0007] Preferably, the lifting mechanism includes hydraulic devices installed on both sides of the fixed plate, and the hydraulic devices can be activated to push the clamping mechanism to perform lifting movements.

[0008] Preferably, the clamping mechanism includes a hollow block fixedly connected to the middle position of the bottom end of the hydraulic device, a sliding rod is slidably connected to the middle position of one side of the hollow block, one side of the sliding rod is fixedly connected to a first movable block sliding in the hollow block, one side of the first movable block is fixedly connected to a first spring, one side of the sliding rod is fixedly connected to a clamping block, and a scraper is fixedly connected to the middle position inside the clamping block.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The dispensing rod structure of this type of placement machine has two sets of clamping blocks on both sides of the main rod body. When the scraper in the clamping block contacts the main rod body, the force on the clamping block can squeeze the first spring through the sliding rod and the first movable block. Due to the reaction force of the first spring being squeezed, the scraper in the clamping block can be pushed to the outer surface of the main rod body through the first movable block and the sliding rod to prevent the main rod body from being subjected to excessive force. At the same time, the clamping mechanism is driven to rise and fall through the lifting mechanism, so that the scraper on the clamping block can quickly clean the outside of the main rod body, thereby improving the overall stability of the dispensing rod structure.

[0013] 2. The dispensing rod structure of this type of placement machine has a card slot on the top of the main rod body. When the main rod body is inserted into the bottom end of the dispensing head, the card blocks on both sides of the dispensing head can be inserted into the card slot on the main rod body. At this time, the main rod body can be quickly installed. When the main rod body needs to be disassembled and replaced, the pull rod on the dispensing head can be pulled out of the card slot on the main rod body by pulling the pull rod. At this time, the main rod body can be quickly replaced. The operation is simple and convenient, and the modular design reduces the overall maintenance cost of the dispensing rod structure.

At the same time, the first movable block 403 can squeeze the first spring 404 on one side. Due to the reaction force of the first spring 404 being squeezed, the scraper 501 in the clamping block 5 can be pushed by the sliding rod 402 and the sliding rod 402, so that the scraper 501 is close to the outer surface of the main rod body 8, and the sliding rod 402 and the clamping block 5 are connected and assembled by bolts, so as to facilitate the rapid replacement and cleaning of the clamping block 5.

[0026] The glue dispensing mechanism 7 comprises a main rod body 8 which is slidably connected to the bottom end of the glue dispensing head 1, and the main rod body 8 can perform glue dispensing work of the placement machine.

[0027] Embodiment 2

[0028] The main difference from the first embodiment is:

[0029] A dispensing rod structure of a placement machine, a limiting mechanism 6 includes a pull rod 601 slidably connected to the bottom ends of both sides of a dispensing head 1, a second movable block 602 is fixedly connected to one side of the pull rod 601, a second spring 603 is fixedly connected to one side of the second movable block 602, a clamping block 604 is fixedly connected to the middle position of the second movable block 602 away from the second spring 603, and the clamping block 604 in the dispensing head 1 is subjected to a force from bottom to top, and the second spring 603 on one side can be squeezed by the second movable block 602. At this time, the clamping block 604 can be retracted into the inside of the dispensing head 1, and due to the reaction force of the second spring 603 being squeezed, when the clamping block 604 is not subjected to force, the second spring 603 can push the clamping block 604 to extend out from the inside of the dispensing head 1 through the second movable block 602, and the second movable block 602 and the clamping block 604 can be pulled to move by the pull rod 601 outside the dispensing head 1.

[0030] A card slot 801 movably connected to the card block 604 is provided at the top of the outside of the main rod body 8, and a guide groove 802 is provided at the top of the main rod body 8. When the main rod body 8 is inserted into the bottom end of the dispensing head 1, the guide groove 802 at the top of the main rod body 8 can push the card block 604, so that the card block 604 is retracted into the inside of the dispensing head 1. When the card block 604 is inserted into the card slot 801 on the main rod body 8, the installation of the main rod body 8 in the middle position of the bottom end of the dispensing head 1 can be completed.

[0031] When the embodiment of the present application is in use, the main rod body 8 is passed through the middle position of the two groups of clamping blocks 5 and inserted into the bottom end of the dispensing head 1. At this time, the two groups of clamping blocks 5 are subjected to force, which can push the first movable block 403 through the sliding rod 402, and make the first movable block 403 squeeze the first spring 404 on one side. At the same time, due to the reaction force of the first spring 404 being squeezed, the scraper 501 in the clamping block 5 can be pushed to the outer surface of the main rod body 8 through the first movable block 403 and the sliding rod 402. At the same time, the card slot 801 at the top of the main rod body 8 can push the two inner parts of the dispensing head 1. The clamping block 604 on the side is moved, and the clamping block 604 is squeezed by the second movable block 602 to squeeze the second spring 603. When the slot 801 on the main rod body 8 moves to the position of the clamping block 604, the force on the second spring 603 is cancelled, and the clamping block 604 can be pushed by the second movable block 602 to insert into the slot 801 on the main rod body 8, and the installation of the main rod body 8 is completed. At this time, the clamping mechanism 4 is driven to move up and down by the hydraulic device 301, and the clamping mechanism 4 drives the clamping block 5 to move up and down on the outer surface of the main rod body 8, thereby scraping the glue outside the main rod body 8.
