Technical Field
[0001] The utility model belongs to the technical field of diode chip production equipment, in particular to a dust collection device for automatically wiping glass paste used in diode chip production. Background Art
[0002] Zener diodes are categorized by their breakdown voltage. Because of this characteristic, they are primarily used as voltage stabilizers or voltage reference components. A characteristic of a Zener diode is that the current across it remains essentially constant until it breaks down, even when reverse current is applied.
[0003] Zener diode chips are very small, and before being cut and separated, they are typically processed using a wafer layout method, undergoing a series of operations such as glass paste coating, swabbing and polishing, photoresist application, and dicing. After the glass paste is applied and solidified, the chip surface requires swabbing and simple polishing to improve the uniformity of the chip surface quality. The solid dust generated during this process must be cleaned promptly, otherwise it will directly affect the operating environment at this station and cause a large amount of dust to adhere to the chip board when it is transferred to subsequent stations.

DETAILED DESCRIPTION
[0019] To more clearly understand the above-mentioned objects, features, and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein may be combined with each other unless they conflict. For ease of description, the words "upper," "lower," "left," and "right" appearing below merely indicate the same directions as in the drawings themselves and do not limit the structure.
[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0021] Examples, such as Figures 1 to 5 As shown, the present invention provides a vacuum cleaner for automatically wiping glass paste used in diode chip production, comprising a workbench 1, a turntable 2 disposed on the workbench 1, a drive motor 3 connected to the turntable 2 at its bottom center, and a control box (not shown) electrically connected to the drive motor 3 disposed on one side. The drive motor 3 drives the turntable 2 to rotate continuously, and the turntable 2 is used to support and rotate the chip board. When a worker holds a wiping cloth and polishing pad and touches the chip board, the worker can complete the corresponding wiping and polishing operations as the chip board rotates.
[0022] On this basis, the workbench 1 provided by the present invention is a hollow structure and the driving motor 3 and the control box are arranged inside it. A double door 1a is provided on the front side of the workbench 1, and a pad cloth 4 distributed around the turntable 2 is provided on the top of the workbench 1. The workbench 1 is provided with a plurality of through holes 1b distributed in a rectangular array on the side direction of the pad cloth 4. A rectangular mounting port 1c is provided at the rear end of the workbench 1, and a bellows 5 is provided in the mounting port 1c. A dust removal bag 6 is provided inside the bellows 5, and a negative pressure fan 7 connected thereto is provided at the end of the bellows 5. A negative pressure air duct 8 connected thereto from top to bottom is provided on the top of the workbench 1, and one end of the negative pressure air duct 8 extends toward the turntable 2. A rotating seat 9 is provided on the top of the workbench 1, and a spiral telescopic tube 10 is provided on the rotating seat 9. A spray gun 11 is provided at one end of the spiral telescopic tube 10, and an air pump 12 is provided at the other end of the spiral telescopic tube 10. Among them, the spatial distribution of the workbench 1, the bellows 5, the negative pressure fan 7 and the air pump 12 is reasonable, and has a reasonable space utilization rate on the basis of realizing their respective functions.
[0023] Specifically, workbench 1, serving as the chip coating station, employs a hollow structure to accommodate the drive motor 3 and control box. A cloth mat 4 is distributed around turntable 2 to collect dust that isn't removed by the negative pressure, increasing dust resistance and preventing dust buildup near this station. A negative pressure blower 7, via a bellows 5 and negative pressure duct 8, provides negative pressure near turntable 2, extracting most of the dust and collecting it in a dust bag 6. The filtered air can then be exhausted for processing or discharged through a duct system along with air from other workstations. The air pump 12 provides compressed gas to the spray gun 11 through the spiral telescopic tube 10. The spray gun 11 can perform basic cleaning operations on the table surface of the workbench 1. Moreover, since the rotating seat 9 provides a rotating ability, the probability of knotting and folding blockage at the position of the spiral telescopic tube 10 can be reduced. The spiral telescopic tube 10 can provide a sufficient stretching radius, which is conducive to the staff holding the spray gun 11 to spray the surface of the workbench 1 comprehensively. The sprayed dust can fall into the inside of the workbench 1 through the through hole 1b, and the inside of the workbench 1 only needs to be cleaned regularly.
[0024] In order to improve the cleanliness of the workstations and taking into account the conditions of adjacent workstations, the present invention provides baffles 13 on the left, right and rear sides of the workbench 1 to reduce the interference and influence of the dust reachable range between adjacent workstations.
[0025] To improve dust collection efficiency, the negative pressure air duct 8 provided in the present invention is provided with an arc-shaped opening 81 at one end facing the turntable 2, with the arc center of the arc opening 81 facing the turntable 2. The opening of the arc-shaped opening 81 is designed to cover a portion of the upper surface and a portion of the lower surface of the turntable 2, increasing the probability of dust entering the negative pressure range and improving the efficiency of dust collection.
[0026] In order to improve the rotational stability of the turntable 2, the longitudinal section of the turntable 2 provided by the utility model is a T-shaped structure. The center of the turntable 2 is keyed to the output shaft of the drive motor 3, and a support seat 14 is provided at the bottom of the turntable 2. The interior of the support seat 14 is provided with a supporting light hole for the rotation of the turntable 2. The supporting light hole acts as a bearing. The support seat 14 is used to improve the flatness of the rotation plane of the turntable 2, thereby ensuring the rotational stability of the chip plate, which is beneficial to improving the wiping efficiency and polishing quality of the chip.
[0027] In order to improve the practicality of the pad cloth 4, in coordination with the turntable 2, the pad cloth 4 provided by the utility model includes a left pad cloth 41 and a right pad cloth 42 spliced together on the left and right sides, and the seams of the left pad cloth 41 and the right pad cloth 42 are provided with a circular opening that cooperates with the turntable 2, so that the two pad cloths 4 can be replaced and cleaned by pulling them left and right.
[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
