Description

Technical Field

[0001] The invention relates to the technical field of diode production, in particular to a diode production pickling device. Background Art

[0002] A diode is an electronic device made of semiconductor materials (silicon, selenium, germanium, etc.). It is the world's first semiconductor device. Types of diodes include ordinary diodes, voltage regulator diodes, switching diodes, light-emitting diodes, etc. They are widely used in household appliances such as televisions and tape recorders, as well as various electronic instruments and equipment.

[0003] During the production process of diodes, charged impurities on their surface need to be removed, and the surface of the diode needs to be cleaned with a pickling device. Traditional pickling devices usually place the semi-finished diodes directly into the pickling device, and then add an appropriate amount of acid solution into the pickling device. At this time, the stirring device in the pickling device is started to increase the fluidity of the acid solution to achieve pickling of the semi-finished diodes.

[0004] In the prior art, the semi-finished diodes are usually placed directly in the cleaning basket. After the diodes are cleaned, the operator will take the cleaning basket out of the pickling tank, move the cleaning basket to the cleaning area, and clean the diodes in the cleaning basket. However, the pickling liquid in the cleaning basket and on the outer wall of the diodes drips onto the workshop floor, causing the workshop to be polluted and affecting the working environment. In addition, there is a lot of pickling liquid attached, so a lot of clean water is needed for cleaning, resulting in a waste of water resources. Therefore, the operator will move the pickled semi-finished diodes from the pickling tank to the upper end of the pickling liquid surface and let it stand for a period of time, so that the pickling liquid in the cleaning basket and on the outer wall of the semi-finished diodes drips into the pickling tank, which increases the production time of the diodes of this batch and affects the pickling of the next batch of diodes to be pickled, resulting in an extension of the production time of the entire diode, which reduces the production efficiency of the diodes. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a diode production pickling device to solve the technical problems in the above-mentioned background technology.

Due to the setting of the first one-way bearing 9, when the driving shaft 6 reverses, it drives the limit shaft 8 to rotate, and a group of limit shafts 8 rotates, driving the two groups of limit blocks 17 on its outer wall to reciprocate.

[0047] See also Figure 5 - Figure 6 The outer walls of the two groups of placement baskets 19 are provided with convex plates 20, and the inner walls of the two groups of placement racks 16 are provided with grooves matching the two groups of convex plates 20.

[0048] See also Figure 1 - Figure 4 A first transmission shaft 10 is movably installed inside the device body 1, and the first transmission shaft 10 is connected to the drive shaft 6 through a synchronous belt. A second one-way bearing 11 is installed at one end of the first transmission shaft 10, and a transmission bevel gear 12 is installed at the upper end of the first transmission shaft 10.

The width of the two sets of reserved grooves 18 is greater than the diameter of the first movable gear 15. When the placement rack 16 is displaced, the setting of the reserved groove 18 avoids the first movable gear 15 from blocking the placement rack 16.

[0051] See also Figure 6 - Figure 8 A second transmission shaft 23 is movably installed inside the two groups of placement baskets 19. The two groups of second transmission shafts 23 extend to one end of the outer wall of the placement basket 19 and are both installed with a transmission gear 24. The two groups of transmission gears 24 are respectively movably connected with the first movable gear 15, and the connection method is a meshing connection. The transmission gear 24 moves one side of the first movable gear 15, the first movable gear 15 rotates, and the transmission gear 24 is meshed with the first movable gear 15, so the transmission gear 24 rotates, thereby driving the second transmission shaft 23 to rotate.

[0052] See also Figure 6 - Fig. 9 A plurality of linkage shafts 22 are movably mounted at the bottom of the placement basket 19, and one linkage shaft 22 is connected to the second transmission shaft 23 through a synchronous belt. The second transmission shaft 23 rotates to drive one linkage shaft 22 to rotate.

[0053] See also Figure 6 - Fig. 9 A linkage gear 27 is installed at one end of a group of linkage shafts 22, and a second movable shaft 25 is movably installed inside the placement basket 19. A second movable gear 26 is installed at one end of the second movable shaft 25, and the second movable gear 26 is meshed and connected with the linkage gear 27. When a group of linkage shafts 22 rotates, the linkage gear 27 is driven to rotate, and the linkage gear 27 is meshed and connected with the second movable gear 26, so the second movable gear rotates, thereby driving the second movable shaft 25 to rotate.

[0054] See also Figure 6 - Fig. 9The second movable shaft 25 is connected to another group of linkage shafts 22 through a synchronous belt, and multiple groups of linkage shafts 22 that are separated are connected through a synchronous belt. The outer walls of the multiple groups of linkage shafts 22 are sleeved with movable rollers 21. When one group of linkage shafts 22 rotates, the second movable shaft 25 drives another group of linkage shafts 222 to rotate, and the multiple groups of linkage shafts 22 that are separated are connected through a synchronous belt. Therefore, the multiple groups of linkage shafts 22 rotate, and the adjacent linkage shafts 22 rotate in opposite directions, thereby driving the multiple groups of movable rollers 21 to rotate.

[0055] The working principle of the present invention is as follows: when the operator uses the device to perform pickling operation on the diode, the operator first takes out the two groups of placement baskets 19 from the two groups of placement racks 16 respectively through the pull ring, and then the operator pours the semi-finished diodes into the two groups of placement baskets 19 respectively, and then the operator puts one group of placement baskets 19 into a group of placement racks 16 at the lower end of the placement bin 2, and the convex plate 20 on the outer wall of the placement basket 19 cooperates with the groove of the placement rack 16 to limit the placement basket 19, and the operator starts the driving motor 5;

[0056] The driving motor 5 is started, driving the driving shaft 6 to reverse, and the driving shaft 6 is respectively connected to one end of a set of limit shafts 8 and one end of the first transmission shaft 10 through a synchronous belt, so one end of a set of limit shafts 8 and one end of the first transmission shaft 10 rotate, and the second one-way bearing 11 is set, and the upper end of the first transmission shaft 10 does not rotate;

[0057] When one set of limit shafts 8 rotates, and the multiple sets of limit shafts 8 are connected by synchronous belts, the multiple sets of limit shafts 8 rotate synchronously. Since the inner walls of the multiple sets of limit blocks 17 are respectively threadedly connected with the two sets of reciprocating thread grooves opened on the outer walls of the multiple sets of limit shafts 8, the multiple sets of limit blocks 17 move downward, thereby driving the two sets of placement racks 16 to move, and the lower set of placement racks 16 carries the placement basket 19 into the pickling chamber 3;

[0058] When a group of placement baskets 19 enters the pickling chamber 3, the driving motor 5 drives the driving shaft 6 to rotate forward. Due to the setting of the first one-way bearing 9, a group of limit shafts 8 stop rotating, and multiple groups of limit shafts 8 stop rotating. Therefore, the two groups of placement racks 16 stop moving, and the driving shaft 6 rotates, driving the stirring blade 7 to rotate, thereby improving the fluidity of the acid solution in the pickling chamber 3, and realizing the pickling of the semi-finished diodes;

[0059] When the diode semi-finished products in a group of placement baskets 19 complete the pickling operation, the driving motor 5 drives the driving shaft 6 to reverse, thereby driving the multiple groups of limit shafts 8 to rotate. Since the outer walls of the multiple groups of limit shafts 8 are provided with two groups of reciprocating thread grooves, the multiple groups of limit blocks 17 move upward, thereby driving the two groups of placement racks 16 to move upward, and drive a group of placement baskets 19 to move out of the pickling bin 3 and into the placement bin 2, turn off the driving motor 5, and then the operator takes out a group of placement baskets 19 from the group of placement racks 16 at the lower end, and puts it into the group of placement racks 16 at the upper end, and then puts another group of placement baskets 19 into the group of placement racks 16 at the lower end;

[0060] When the two groups of placement baskets 19 are placed, the drive motor 5 is started to drive the drive shaft 6 to reverse, and the two groups of placement racks 16 drive the two groups of placement baskets 19 to move downward, and the transmission gear 24 on one side of one group of placement baskets 19 moves to the side of the first movable gear 15, and the other group of placement baskets 19 enters the pickling chamber 3, and the drive motor 5 drives the drive shaft 6 to rotate forward, and the multiple groups of limit shafts 8 stop rotating, and the two groups of placement racks 16 and the two groups of placement baskets 19 stop moving;

[0061] The driving shaft 6 rotates forward to drive the first transmission shaft 10 to rotate, thereby driving the transmission bevel gear 12 to rotate, and the transmission bevel gear 12 is meshed and connected with the movable bevel gear 14, so the movable bevel gear 14 rotates, thereby driving the first movable shaft 13 to rotate, and then driving the first movable gear 15 to rotate, and the transmission gear 24 is meshed and connected with the first movable gear 15, so the transmission gear 24 rotates, thereby driving the second transmission shaft 23 to rotate, and the second transmission shaft 23 is connected to a group of linkage shafts 22 through a synchronous belt, so a group of linkage shafts 22 rotates, thereby driving a group of movable rollers 21 to rotate, and multiple groups of spaced linkage shafts 22 are connected through synchronous belts, so multiple groups of spaced linkage shafts 22 rotate, thereby driving multiple groups of spaced movable rollers 21 to rotate;

[0062] When one group of linkage shafts 22 rotates, the linkage gear 27 is driven to rotate, and the linkage gear 27 is meshed and connected with the second movable gear 26, so the second movable gear 26 rotates, thereby driving the second movable shaft 25 to rotate, and the second movable shaft 25 is connected to another group of linkage shafts 22 through a synchronous belt, so the other group of linkage shafts 22 rotates, thereby driving another group of movable rollers 21 to rotate, and multiple groups of spaced linkage shafts 22 are connected through synchronous belts, so multiple groups of spaced linkage shafts 22 rotate, thereby driving multiple groups of spaced movable rollers 21 to rotate, so the adjacent movable rollers 21 rotate in opposite directions, so that a group of diode semi-finished products in the placement basket 19 shakes, accelerating the pickling liquid attached to the inner wall of the placement basket 19 and the outer wall of the diode semi-finished products to drip into the pickling bin, and at the same time, the adjacent movable rollers 21 rotate in opposite directions, avoiding the accumulation of diode semi-finished products and improving the processing efficiency of diode semi-finished products;

[0063] The present invention arranges a placement rack 16 and a placement basket 19. When one group of placement baskets 19 carries the diode semi-finished products for pickling, another group of placement baskets 19 carries the diode semi-finished products that have completed the pickling operation and is suspended on the upper end of the pickling chamber 3, so that the pickling liquid on the outer wall of the diode semi-finished products drips into the pickling chamber 3, thereby improving the processing efficiency of the diode semi-finished products.
