Description

Technical Field

[0001] The utility model relates to the technical field of semiconductor welding, and more specifically, to a chain-type fixed-distance vacuum furnace plate conveying mechanism. Background Art

[0002] At present, with the development of semiconductor technology, electronic technology is developing towards high power, high density and integration, and higher and more comprehensive reliability requirements are put forward for the packaging and welding of high-power devices.

[0003] However, for the chain-type vacuum furnace, since the chain is of a three-section type, when the product is moved into the vacuum area, the moving distance deviation is often too large, resulting in the inability to close the vacuum box and crushing the product. Although there is a method of installing a sensor in the furnace to sense and confirm the product position, the high temperature in the welding furnace will seriously affect the service life and performance of the sensor. In view of this, we propose a chain-type fixed-distance vacuum furnace plate conveying mechanism. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet the actual needs, and provide a chain-type fixed-distance vacuum furnace plate conveying mechanism to solve the technical problems that for the current chain-type vacuum furnace, since the chain is of a three-section type, when the product is moved into the vacuum area, the moving distance deviation is often too large, resulting in the inability to close the vacuum box and crushing the product, and although there is a method of installing a sensor in the furnace to sense and confirm the product position, the high temperature in the welding furnace will seriously affect the service life and performance of the sensor.

[0005] To solve the above technical problems, the utility model provides the following technical solutions: A chain-type fixed-distance vacuum furnace plate conveying mechanism includes a chain drive assembly arranged on one side of the upper conveyor of the vacuum welding furnace and a moving distance detection assembly arranged on the other side of the conveyor;

The block B is fixed on the chain B, and the sensor bracket is fixed on one side of the support structure. The sensor body is fixedly installed on the sensor bracket, and the block B cooperates to trigger the sensor body.

[0008] With the arrangement of chain drive in the utility model, when two chain A are driven by the chain drive shaft to rotate, the stoppers A arranged on the two chain A will be driven to move, realizing the pushing of the products. When the products slip or get stuck on the two chain A, the two stoppers A will be driven by the two chain A to push the products to move, thus avoiding the problem of the front and rear products colliding with each other, effectively preventing the products from slipping and jamming during transmission, and making the distance between the products equal, avoiding the product loss caused by position deviation.

[0009] Preferably, chain drive shafts are rotatably arranged in both the vacuum welding furnace and the conveyor. One end of the chain drive shaft arranged in the vacuum welding furnace is fixedly installed with a sprocket, and the sprocket is meshed and cooperated with the corresponding chain A.

[0013] Preferably, the length of the chain B is an integer multiple of the single - time product moving distance, and the stopper B is welded on the chain B at a fixed distance.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. With the arrangement of chain drive in the utility model, when two chain A are driven by the chain drive shaft to rotate, the stoppers A arranged on the two chain A will be driven to move, realizing the pushing of the products. When the products slip or get stuck on the two chain A, the two stoppers A will be driven by the two chain A to push the products to move, thus avoiding the problem of the front and rear products colliding with each other, effectively preventing the products from slipping and jamming during transmission, and making the distance between the products equal, avoiding the product loss caused by position deviation.

[0023] As Figures 1 to 4 shown, a chain-type fixed-distance vacuum furnace plate transfer mechanism related to the present utility model includes a chain drive assembly arranged on one side of the conveyor on the vacuum welding furnace and a moving distance detection assembly arranged on the other side of the conveyor;

[0024] In the embodiment of the present utility model, the chain drive assembly includes two chains A1 and two blocks A2 for assisting in pushing the product. The two chains A1 and the two blocks A2 are both arranged on the conveyor, and the two blocks A2 are respectively fixed on the corresponding chains A1. A chain drive shaft 11 is rotatably arranged in both the vacuum welding furnace and the conveyor. One end of the chain drive shaft 11 arranged in the vacuum welding furnace is fixedly installed with a sprocket, and the sprocket is meshed and matched with the corresponding chain A1. The length of the chain A1 is an integer multiple of the single-time product moving distance, and the distance between the two blocks A2 remains unchanged when moving. Through the setting of chain drive, when the two chains A1 are driven by the chain drive shaft 11 to rotate, the blocks A2 arranged on the two chains A1 will be driven to move, realizing the pushing of the product. When the product slips or gets stuck on the two chains A1, the two blocks A2 will be driven by the two chains A1 to push the product to move, thereby avoiding the problem of the front and rear products colliding, effectively preventing the product from slipping and jamming during transmission, and making the distance between the products equal, avoiding product loss caused by position deviation.

[0025] In an embodiment of the present utility model, the moving distance detection assembly includes a chain B3, a stop block B4, a driving wheel body 5, an auxiliary wheel body 6, an auxiliary wheel bracket 7, a sensor body 8, a sensor bracket 9, and a vertical plate 10. The driving wheel body 5, the auxiliary wheel body 6, the auxiliary wheel bracket 7, and the vertical plate 10 form a support structure for installing the chain B3, and the support structure is fixedly arranged on one side of the conveyor. The stop block B4 is fixedly arranged on the chain B3, and the sensor bracket 9 is fixedly arranged on one side of the support structure. The sensor body 8 is fixedly installed on the sensor bracket 9, and the stop block B4 cooperates to trigger the sensor body 8. The auxiliary wheel bracket 7 is fixedly arranged on one side of the vertical plate 10, and an auxiliary wheel body 6 is rotatably arranged at the center of one side of the auxiliary wheel bracket 7. The driving wheel body 5 is fixedly installed at one end of a chain driving shaft 11 arranged in the conveyor, and the chain B3 is installed on the driving wheel body 5 and the auxiliary wheel body 6. The length of the chain B3 is an integer multiple of the single product moving distance, and the stop block B4 is welded on the chain B3 at a fixed distance. Through the setting of the moving distance detection, when the two chains A1 drive the product to move, the chain driving shaft 11 on the conveyor drives the driving wheel body 5 to rotate, and the driving wheel body 5 drives the chain B3 to move on the driving wheel body 5 and the auxiliary wheel body 6, so as to drive the stop block B4 to pass by the sensor body 8, so that the sensor body 8 controls the moving distance of the product by detecting the stop block B4.

[0026] Working principle: This embodiment provides a chain-type fixed-distance vacuum furnace plate conveying mechanism. When in use, two rolling chains A1 drive the product to move. When the product slips or gets stuck on the two chains A1, the two stop blocks A2 will be driven by the two chains A1 to push the product to move, thus avoiding the problem of collision between the front and rear products, effectively preventing the product from slipping and jamming during transmission, and making the distance between products equal, avoiding product loss caused by position deviation. And when driving the product to move, the chain driving shaft 11 on the conveyor drives the driving wheel body 5 to rotate, and the driving wheel body 5 drives the chain B3 to move on the driving wheel body 5 and the auxiliary wheel body 6, so as to drive the stop block B4 to pass by the sensor body 8, so that the sensor body 8 controls the moving distance of the product by detecting the stop block B4.
