Description

Technical Field

[0001] The utility model belongs to the technical field of electronic component manufacturing, and further relates to the technical field of axial lead device manufacturing, and specifically relates to a planetary rolling plating device for axial bipolar lead devices. Background Art

[0002] The electroplating methods for semiconductor discrete devices usually adopt two methods: rack plating and barrel plating. For axial bipolar lead devices, due to their special structure, the existing technology cannot be rack-plated, and barrel plating is usually adopted. The barrel plating method is also called drum electroplating. It is to place a certain number of axial bipolar lead devices in a special drum and deposit a metal coating on the surface of the parts by indirect conductive method while rolling. At present, the existing technology mainly adopts matte electroplating tin for axial bipolar lead devices.

[0003] The drum plating mode has the following problems:

[0004] 1. The axial bipolar lead device is contacted with the axial bipolar lead device through the stirring of the anode rod in a special barrel. The product (i.e. the part to be plated - the axial bipolar lead device, referred to as the product) is contacted with the product in a rolling state to achieve indirect conduction for barrel plating. However, as the product is stirred, the leads of the axial bipolar lead device will bend, and even cause the products to be entangled together in a twisted shape, forcing the addition of two processes of sorting and straightening, and multiple people are involved in product sorting and lead straightening, resulting in low production efficiency.

[0005] 2. During the roller plating process of axial bipolar lead devices, the friction between products will also cause the surface of the non-electroplated parts to wear and even damage, which directly affects the product quality.

[0006] In view of this, the present utility model is proposed. Summary of the invention

[0007] The technical problem to be solved by the utility model is to solve the problem that the existing axial bipolar lead devices are prone to lead bending, product entanglement and product surface friction and wear during the roll plating process.

[0008] To this end, the utility model provides a planetary rolling plating device for axial bipolar lead devices, such as Figure 1-8 As shown. Includes:

[0012] The cover plate 10101, side plate 10102, bottom plate 10103, left end plate 10104 and right end plate 10105 are insulating plates, which are fixedly connected by screw holes. The side plate 10102 and the right end plate 10105 have the same height.

[0019] The maximum distance of the two top fixings 206 installed on the two clamping arms 201 when compressed is greater than the thickness of the electrode head 10203, so that the electrode head 10203 can be reliably inserted through the clamping opening 202. When the two top fixings 206 on the two clamping arms 201 are elastically extended, they extend into the electrode head through hole 10203A from both ends of the electrode head through hole 10203A respectively, and make electrical contact with the electrode head through hole 10203A.

[0025] The right planetary gear set 4 includes a right positioning pinion 401 , a right driving pinion 402 , a right large gear 403 , a right main shaft mounting seat 404 , and a revolving bearing box 405 .

[0029] The left planetary gear set 3 and the right planetary gear set 4 have the same number of main shaft mounting seats and spring clamps 2, and their placement positions are distributed in a one-to-one correspondence, so that the left and right sides cooperate with each other.

[0030] The left planetary gear set 3 and the right planetary gear set 4 are respectively installed on the left and right side plates at the bottom of the device bracket 8, and the distance between the left and right side plates and the space between the side plates are jointly determined by the sizes of the left planetary gear set 3, the right planetary gear set 4, the main shaft 5, the spring clamp 2, and the clamp box 1.

[0034] The movable connection means that when one of the connected parties rotates, the other connected party does not rotate accordingly.

DETAILED DESCRIPTION

[0051] like Figure 1-8 As shown, the planetary rolling plating device for axial bipolar lead devices has the following specific implementation methods:

[0052] All electrical connection parts are made of copper.

[0053] The partition plate 103 is a plastic partition plate.

[0054] The cover plate through hole 10101A and the bottom plate through hole 10103A are rectangular.

[0055] The electrode head 10203 is square, and the electrode head through hole 10203A is circular.

[0056] The body of the spring clamp 2 is circular, the clamping opening 202 is U-shaped, and the top fixing piece 206 is spherical (called a top ball).

[0057] 1. Axial bipolar lead device fixture box

[0058] Remove the top cover 10101 and place the product in the four-grid trough 104 (30-40 products are placed in each grid). During the rotation of the product, the two ends of the lead wire touch the copper conductive plates 10201 on both sides back and forth. Its conductive structure consists of the copper electrode head 10203 connected to the copper end conductive plate 10202, and the copper end conductive plate 10202 connected to the copper side conductive plate 10201 to make it conductive; the non-contact surface of the product is separated by a plastic partition plate 103 to reduce contact with the electroplating solution, thereby minimizing the non-electroplating copper surface from being electroplated; the cover 10101 and the bottom plate 10103 are both provided with liquid flow channels, which allow the electroplating solution to flow steadily without letting the product fall.

[0059] In order to prevent the product from rotating in the fixture box, a fixture box is designed with 4 material troughs, where the length of the material trough is specified to exceed the product size by 3 mm -4 mm, the width of the material trough cannot exceed 3 / 5 of the product length, and the height of the material trough cannot exceed 2 / 5 of the product length. This ensures that the product will not rotate in the fixture box, causing lead bending, product entanglement, etc., and also allows the product to move as much as possible toward the front and rear side conductive plates, thereby reducing friction damage on the product surface.

[0060] 2. Spring gripper

[0061] The top screw 204 connects the spring 205 and the top ball 206 together by means of a thread. The spring clamp 2 is made of copper. The copper electrode head 10203 can be made conductive through electrical transmission. The electrode head 10203 of the fixture box is fixed by the pressure of the spring (the spring force can be adjusted by the screw), so that the fixture box can be quickly taken in and out.

[0062] 3. Planetary gear operation structure

[0063] The planetary gear operating structure consists of a left planetary gear set 3, a right planetary gear set 4 and a main shaft 5.

[0064] The left planetary gear set 3 drives the left large gear 303 to rotate by the meshing of the left positioning small gear 301 and the left driving small gear 302. The left large gear 303 and the driving wheel 305 are connected together through the left gear connector 307 to drive the rotation. The driving wheel 305 meshes with the six driven wheels 306 to realize the self-rotation of the spring clamp.

[0065] The right planetary gear set 4 drives the right large gear 403 to rotate by the engagement of the right positioning small gear 401 and the right driving small gear 402. The right large gear 403 and the orbital bearing box 405 are connected together through the right main shaft mounting seat 404 to drive the rotation and realize the orbital revolution of the spring clamp.

[0066] The specific working mechanism is as follows:

[0067] The first motor (left motor) is connected to the left driving pinion 301, and the rotation of the motor drives the left driving pinion 301, and the left driving pinion 301 drives the left transmission pinion 302, and the left transmission pinion 302 drives the left large gear 303 to rotate. The left large gear 303 is connected to the driving wheel 305 through the left gear connector 307 to rotate, and the rotating driving wheel 305 drives the five driven wheels 306 to rotate. The driven wheel 306 is connected to the spring clamp 2, which drives the spring clamp 2 to rotate and at the same time drives the fixed clamp box 1 on the spring clamp 2 to rotate, thereby solving the principle of self-rotation of the clamp box.

[0068] The second motor (right motor) is connected to the right driving pinion 401, and the rotation of the motor drives the right driving pinion 401, and the right driving pinion 401 drives the right transmission pinion 402, and the right transmission pinion 402 drives the right large gear 403 to rotate. The right large gear 403 is connected to the right spindle mounting seat 404 to drive the revolving bearing box 405 to rotate. At this time, the revolving bearing box 405 transmits the power to the self-rotating gear box 304 through the clamp box 1 on the 5 spring clamp jaws 2 during the rotation process, so that the self-rotating gear box 304 and the revolving bearing box 405 revolve while the clamp box 1 rotates, thereby solving the principle that the clamp box can rotate and revolve at the same time.

[0069] 4. Electroplating conductive structure

[0070] The copper rod on the barrel plating box is connected to the main shaft in the form of a soft conductive wire connection, and the spring clamp is made conductive by filling the self-rotating gear box 304 with conductive glue, thereby achieving electroplating.

[0071] In order to reduce the amount of electricity consumed by the fixture box itself during the electroplating process, the fixture box conductive device 102 does not use a whole conductive box made of copper or conductive metal, but chooses to transfer electricity to two electrode heads 10203 on the spring clamp 2, and the electrode heads 10203 transfer electricity to the end conductive plate 10202, and then from the end conductive plate 10202 to the side conductive plate 10201.

[0072] During the roller plating process, the product in the fixture box continuously contacts the side conductive plates 10201 on both sides through the movement of rotation and revolution, so that the product is energized to complete the electroplating process. Finally, the conductive parts are spliced ​​together by the plastic cover plate 10101, two side plates 10102, the bottom plate 10103, the left end plate 10104, and the right end plate 10105.

[0073] In order to allow the products to be placed in the fixture box in batches and quickly, cover plate retrieval grooves 10106 are opened at the upper ends of the two side plates 10102 for inserting and removing the cover plate 10101, and each grid of the fixture box is separated by a partition plate 103.

[0074] 5. Device operation mechanism

[0075] The axial bipolar lead device is placed in a fixture box. The fixture box has four grids and each grid holds 30-40 products. The left and right sides of the fixture box are made of copper conductive plates, which can make the top of the product lead contact the conductive plate to generate conductivity for electroplating. The front and back sides of the fixture box are equipped with copper conductive blocks and guide grooves, which are convenient for energizing the internal copper conductive plates and quickly fixing them on the spring clamps; the two clamping arms of the spring clamps are equipped with spring-type top beads, and the fixture box can be quickly fixed in the spring clamp through the pressure of the spring, and can also be quickly clamped; the planetary gear operation structure drives the gear set through two motors, one motor drives the driving wheel in the left planetary gear set, and the driving wheel drives the driven wheel to rotate by gear meshing, and the other motor drives the revolving bearing box in the right planetary gear set to revolve, thereby increasing the rotation of the product in the fixture box, better touching the copper conductive plates on the left and right sides, and completing the electroplating process requirements of the axial bipolar lead device in a short time.

[0076] Finally, it should be noted that the above embodiments are only examples for clear explanation. The present utility model includes but is not limited to the above embodiments. It is not necessary and impossible to list all implementation methods here. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. All implementation methods that meet the requirements of the present utility model belong to the protection scope of the present utility model.
