Description

Technical Field

[0001] The invention relates to the technical field of electric contact processing and welding, and in particular to a multi-angle processing and welding device and a welding method for electric contacts. Background Art

[0002] The existing electrical contacts have complex shapes. After the electrical contacts are clamped, the processed positions of the electrical contacts cannot be guaranteed to be in the same plane. Therefore, when welding different planes of the electrical contacts, manual adjustment is required, and the processing efficiency is low.

[0003] A Chinese patent (authorization announcement number CN222327054U) discloses a welding device for an electric contact processing procedure, comprising a base, the surface of the base being rotatably connected to a rotating seat, the surface of the rotating seat being provided with a clamping mechanism for clamping the electric contact, the clamping mechanism comprising a first slide bar and a second slide bar, both of which are slidably connected to the rotating seat, a pad being provided on the surface of the rotating seat, the pad being located between the first slide bar and the second slide bar, a support rod being fixedly mounted on the side wall of the base, and a slot being provided at the port of the support rod for engaging a welding gun.

[0004] The above scheme achieves the effect of clamping the electric contact for multi-angle rotation, but in the process of welding the electric contact, it is inevitable that metal debris will fall, and the size of the electric contact is usually small. If the clamping mechanism is not cleaned for a long time, a large amount of metal debris will accumulate on the clamping mechanism, which will not only affect the normal operation of the clamping mechanism, but also cause the clamping mechanism to be unable to stably clamp the electric contact. If the above situation is to be avoided, the existing method is to manually clean the clamping mechanism, but the workload is large, and after a large amount of metal debris accumulates, it is difficult to clean. If blowing is used for cleaning, due to the small size and light weight of the metal debris, the metal debris will splash everywhere during the process of blowing away the metal debris.

[0035] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] Reference Figure 1-Figure 5: A multi-angle processing and welding device for electric contacts, comprising a receiving unit 2 for receiving the electric contact 3; the receiving unit 2 comprises a plurality of receiving plates 21 evenly arranged in the horizontal direction, the receiving plates 21 can rotate around the length direction of the receiving plates 21 themselves, the receiving unit 2 also comprises a driving unit 22 for driving all the receiving plates 21 to rotate synchronously, the receiving plates 21 rotate 180 degrees each time, when the end face of the receiving plate 21 is parallel to the horizontal plane, the upper end faces of all the receiving plates 21 form a receiving surface, the receiving surface receives the electric contact 3, when the end face of the receiving plate 21 is not parallel to the horizontal plane, the receiving plate 21 discharges metal debris.

[0037] The existing processing and welding equipment is mainly composed of a welding unit, a clamping unit 1 and a receiving unit 2. During welding, first, the electric contact 3 needs to be placed on the receiving unit 2, and then the electric contact 3 is clamped and limited by the clamping unit 1 set on the receiving unit 2 to prevent the electric contact 3 from being displaced in the subsequent welding process. Then, the electric contact 3 is welded by the welding unit. There are two main welding methods for existing multi-angle welding. One is to make the welding unit move at multiple angles, and the other is to make the clamping unit 1 clamp the electric contact 3 and then drive the electric contact 3 to move at multiple angles, and the position of the welding unit remains unchanged. The above two multi-angle welding methods are both existing technologies and will not be repeated here. The present invention is mainly designed for the first welding method, that is, the welding unit can move at multiple angles, and the clamping unit 1 will not drive the electric contact 3, and the clamping unit 1 only has a limiting function for the electric contact 3. During the welding process of the welding unit on the electric contact 3, it is unavoidable to avoid the splashing of metal debris. The traditional receiving unit 2 is a fixed platform structure and does not have the ability to clean the metal debris autonomously. This easily leads to the accumulation of metal debris on the receiving unit 2, and the workload of manual cleaning is large.

[0038] In order to avoid the above situation, the receiving unit 2 is redesigned so that the receiving unit 2 can clean itself after receiving the electric contact 3 each time, ensuring that the receiving surface of the receiving unit 2 is in a clean state before receiving the electric contact 3, thereby reducing the work intensity of the staff. The specific structure and working process of the receiving unit 2 are as follows:

[0039] The clamping unit 1 includes a clamping plate 11, a first screw rod 12 and a first rotation driver 13. Two clamping plates 11 are provided. The two clamping plates 11 are symmetrically arranged horizontally about the receiving unit 2. The two clamping plates 11 can approach or move away from each other in the horizontal direction. The first screw rod 12 penetrates the two clamping plates 11 in sequence in the horizontal direction. The first screw rod 12 has two sections of threads with opposite rotation directions. The two clamping plates 11 are respectively located on the two sections of threads. The first rotation driver 13 is arranged at one end of the first screw rod 12. The first rotation driver 13 drives the two clamping plates 11 to move through the first screw rod 12.

[0040] A pressure sensor is provided on the end face of the receiving plate 21. When the pressure sensor detects the pressure of the electric contact 3, it means that the electric contact 3 is in a welding state. If the electric contact 3 is removed, the pressure sensor does not detect the pressure at this time, and the drive unit 22 is started at this time. Since the single welding time of the electric contact 3 is basically the same, the rated start time can also be set for the drive unit 22, so that the drive unit 22 is started intermittently. The specific start mode of the drive unit 22 can be set according to the actual situation. Each receiving plate 21 has two end faces that can receive the electric contact 3, and only one end face can receive the electric contact 3 at a time. Before welding, the upper end faces of all the receiving plates 21 are parallel to the uniform horizontal plane, and at this time, the upper end faces of all the receiving plates 21 form a receiving surface, which is used to receive the electric contact 3. The electric contact 3 is placed on the receiving surface, and then the clamping unit 1 clamps the two ends of the electric contact 3 to ensure that the electric contact 3 will not be displaced during the welding process. Then the welding unit welds the electric contact 3 according to the preset program. During the welding process, metal debris will splash everywhere, and some metal debris will splash onto the receiving surface. At this time, metal debris will remain on the upper end surface of the receiving plate 21. After the welding is completed, the clamping unit 1 releases the electric contact 3, and the staff removes the electric contact 3. At this time, the driving unit 22 drives all the receiving plates 21 to rotate synchronously. During the rotation of the receiving plate 21, the metal debris originally located on the upper end surface of the receiving plate 21 The metal debris slides off due to the rotation of the receiving plate 21. When the receiving plate 21 rotates 80 degrees, the driving unit 22 stops running, thus completing the cleaning of the metal debris on the receiving plate 21. After all the receiving plates 21 rotate 180 degrees, the upper end surface of the receiving plate 21 is parallel to the horizontal plane again, so that the receiving surface is formed again, and no metal debris remains on the receiving surface at this time, thereby avoiding the accumulation of metal debris on the upper part of the receiving unit 2 during the process of receiving the electric contact 3, thereby avoiding the occurrence of defective products and ensuring the yield of welding of the electric contact 3.

[0041] By providing a plurality of receiving plates 21 arranged in the horizontal direction and enabling the receiving plates 21 to rotate around their own length direction, when receiving the electric contact 3, the upper end surfaces of all the receiving plates 21 are parallel to the horizontal plane. At this time, the upper end surfaces of all the receiving plates 21 form a receiving surface, which supports the electric contact 3. After welding, the driving unit 22 drives all the receiving plates 21 to rotate 180 degrees synchronously, so that the metal debris originally located on the upper part of the receiving plate 21 can be discharged smoothly, and a new receiving surface can be formed at the same time, ensuring that the receiving unit 2 can perform self-cleaning after each welding of the electric contact 3, thereby ensuring the cleanliness of the receiving surface of the receiving unit 2, avoiding the electric contact 3 from tilting when placed on the receiving surface, thereby avoiding the occurrence of defective products, and reducing the cleaning workload of the staff for the receiving unit 2. In addition, cleaning the receiving surface after each welding is completed is better than cleaning it after using it many times.

[0042] Reference Figure 6 and Figure 7 The driving unit 22 includes a gear 221 fixedly arranged at the rotating end of the receiving plate 21, and the gear 221 rotates synchronously with the receiving plate 21. The driving unit 22 also includes a rack 222 movable along the arrangement direction of the receiving plate 21, and the rack 222 is meshed with all the gears 221. A push-pull unit 223 is arranged at the end of the rack 222 to push the rack 222 to move back and forth.

[0043] Since metal debris will fly during welding, if a belt-driven receiving plate 21 is used to rotate, metal debris will be mixed into the belt. In this way, the metal debris will not only damage the belt, but also the metal debris mixed into the belt transmission position will cause the belt to slip. This will cause the receiving plate 21 to be unable to rotate synchronously. In order to overcome the above problems, a rack 222 and a gear 221 are provided. A gear 221 is provided at the rotating end of each receiving plate 21. The rack 222 is pushed back and forth by the push-pull unit 223 to realize the rotation of the gear 221, thereby causing the receiving plate 21 to rotate. A small amount of metal debris cannot affect the meshing of the gear 221 and the rack 222, thereby ensuring the synchronization of the rotation of the receiving plate 21 during use.

[0044] Reference Figure 9-11 The push-pull unit 223 includes a rotating disk 2231 rotatably arranged on one side of the gear 221, a first extension column 2233 is arranged at the end of the rotating disk 2231, and the diameter of the circle formed by the first extension column 2233 when the rotating disk 2231 rotates is the same as the diameter of the gear 221, and a second rotating driver 2232 for driving the rotating disk 2231 to rotate is arranged at the end of the rotating disk 2231. When the rotating disk 2231 rotates one circle, the rack 222 completes a reciprocating movement.

[0045] The second rotary driver 2232 is preferably a steering gear. When the second rotary driver 2232 drives the rotating disk 2231 to rotate, the rack 222 completes a reciprocating displacement every time the rotating disk 2231 rotates one circle, and the diameter of the circle formed by the first extension column 2233 when the rotating disk 2231 rotates is the same as the diameter of the gear 221. In this way, the rack 222 drives the gear 221 to rotate 180 degrees in the forward direction and then 180 degrees in the reverse direction every time the rotating disk 2231 rotates one circle. It is worth noting that the rotating disk 2231 stops every time it rotates half a circle, so the gear 221 also rotates half a circle, that is, 180 degrees, each time, so that the effect of driving the receiving plate 21 to rotate 180 degrees is achieved.

[0046] Reference Fig.11 A translation frame 2234 is arranged between the rotating disk 2231 and the rack 222 so as to move along the moving direction of the rack 222. A first slide groove 2235 and a second slide groove 2236 are vertically opened on both sides of the translation frame 2234 respectively. The first extension column 2233 is slidably matched with the first slide groove 2235. A second extension column 2237 is horizontally arranged on the side of the rack 222, and the second extension column 2237 is slidably matched with the second slide groove 2236.

[0047] When the driving unit 22 is running, the second rotation driver 2232 drives the rotating disk 2231 to rotate 180 degrees, and the translation frame 2234 moves in the horizontal direction under the drive of the first extension column 2233, and the moving distance of the translation frame 2234 is the same as the diameter of the rotating disk 2231. The second slide groove 2236 drives the rack 222 through the second extension column 2237, and the rack 222 drives the gear 221 to rotate, so that the gear 221 rotates 180 degrees, and finally the receiving plate 21 rotates 180 degrees synchronously with the gear 221.

[0048] Reference Figure 8 and Fig.10 A support unit 23 is provided below the receiving plate 21. The support unit 23 includes a support plate 231 that moves along the length direction of the receiving plate 21. When the receiving surface is formed, the support plate 231 moves to the bottom of the receiving plate 21 and provides support for all the receiving plates 21.

[0049] When the receiving plate 21 rotates, the support plate 231 is in a retracted state, and the support plate 231 will not hinder the rotation of the receiving plate 21. When the receiving plate 21 rotates to a horizontal state, the support plate 231 extends and supports all the receiving plates 21, ensuring that the receiving plate 21 will not rotate due to external pressure when receiving the electrical contact 3. The support unit 23 also includes a second screw rod 232 that is rotatably arranged along the length direction of the receiving plate 21. The second screw rod 232 penetrates the support plate 231 and is threadedly matched with the support plate 231. A third rotation driver 233 is arranged at the end of the second screw rod 232. The third rotation driver 233 is preferably a servo motor. The third rotation driver 233 drives the support plate 231 to move telescopically through the second screw rod 232.

[0050] Reference Figure 3 A blanking cavity 24 is provided below the receiving plate 21, and a fan 25 is provided on one side of the blanking cavity 24. The air in the blanking cavity 24 flows from top to bottom under the action of the fan 25, and each receiving plate 21 is provided with a plurality of ventilation holes.

[0051] During welding, the fan 25 is started, and the fan 25 extracts the air in the blanking cavity 24, so that the air in the blanking cavity 24 flows from top to bottom in the vertical direction. Since a plurality of vents are evenly arranged on the receiving plate 21, the air around the electric contact 3 also flows from top to bottom during welding, so that the metal debris generated during welding can fall quickly. It is worth noting that the falling metal debris will block some of the vents under the action of the flowing air, but after each welding of the electric contact 3 is completed, all the receiving plates 21 are rotated 180 degrees, and the fan 25 is still in operation, so that the metal debris originally blocked in the vents will be blown down by the flowing air, avoiding the situation where the metal debris blocks the vents.

[0052] Reference Figure 2-Figure 4 A discharge unit 26 for discharging metal chips is provided at the bottom of the blanking cavity 24 .

[0053] The discharge unit 26 includes a spiral blade 261 and a fourth rotary driver 262. The spiral blade 261 is rotatably arranged at the bottom of the blanking cavity 24 along the length direction of the receiving plate 21. The fourth rotary driver 262 is arranged at the end of the spiral blade 261. The fourth rotary driver 262 is preferably a servo motor.

[0054] Reference Figure 4 and Figure 6 The collecting box 27 is arranged at one side of the blanking cavity 24 and is connected to the blanking cavity 24. The metal debris discharged by the discharge unit 26 is collected by the collecting box 27. The fan 25 is arranged above the collecting box 27. An air outlet 271 is opened on the side wall of the collecting box 27. The end of the air outlet 271 is connected to a gas filter.

[0055] The bottom of the collecting box 27 collects the metal scraps, and the air drawn out by the fan 25 is exhausted through the air outlet 271 and filtered by a gas filter, which is a prior art and will not be described in detail herein. In this way, during welding, harmful smoke generated by welding can be prevented from being dispersed.

[0056] Reference Figure 6 : A sponge 28 is arranged at the lower part of the fan 25.

[0057] This ensures that metal debris will not be discharged by the fan 25 when the fan 25 is running.

[0058] Reference Figure 1-Figure 11 The present invention also relates to a multi-angle processing and welding method for electric contacts, which uses a multi-angle processing and welding device for electric contacts, and the specific steps are as follows:

[0059] S1, placing the electric contact 3 on the receiving surface formed by the receiving plate 21, and clamping the electric contact 3 by the clamping unit 1;

[0060] S2, the welding unit welds the electric contact 3, and removes the electric contact 3 after the welding is completed;

[0061] S3, the driving unit 22 drives all the receiving plates 21 to rotate synchronously, and the metal debris falling on the receiving plates 21 falls from the receiving plates 21 due to the rotation and tilt of the receiving plates 21. When all the receiving plates 21 rotate 180 degrees, the driving unit 22 stops running.

[0062] Working principle: Before welding, the upper end surfaces of all the receiving plates 21 are evenly parallel to the horizontal plane, and at this time, the upper end surfaces of all the receiving plates 21 form a receiving surface, which is used to receive the electric contact 3. The electric contact 3 is placed on the receiving surface, and then the clamping unit 1 clamps the two ends of the electric contact 3 to ensure that the electric contact 3 will not be displaced during the welding process. Then the welding unit welds the electric contact 3 according to the preset program. During the welding process, metal debris will splash everywhere, and some metal debris will splash onto the receiving surface. At this time, metal debris will remain on the upper end surface of the receiving plate 21. After the welding is completed, the clamping unit 1 releases the electric contact 3, and the staff removes the electric contact 3. At this time, the driving unit 22 drives all the receiving plates 21 to rotate synchronously. During the rotation of the receiving plate 21, the metal debris originally located on the upper end surface of the receiving plate 21 is moved. The metal debris slides off due to the rotation of the receiving plate 21. When the receiving plate 21 rotates 80 degrees, the driving unit 22 stops running, thus completing the cleaning of the metal debris on the receiving plate 21. After all the receiving plates 21 rotate 180 degrees, the upper end surface of the receiving plate 21 is parallel to the horizontal plane again, so that the receiving surface is formed again, and no metal debris remains on the receiving surface at this time, thereby avoiding the accumulation of metal debris on the upper part of the receiving unit 2 during the process of receiving the electric contact 3, thereby avoiding the occurrence of defective products and ensuring the yield of welding of the electric contact 3.

[0063] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
