Description

Technical Field

[0001] The utility model relates to the field of manufacturing technology, and in particular to a welding fixing device. Background Art

[0002] In the manufacturing field of the semiconductor industry (especially in key links such as chip packaging and assembly), high requirements are imposed on the welding process. In these application scenarios, strict standards are set for the geometric accuracy of welded parts (such as the parallelism and perpendicularity of the end faces). This is because any slight deformation or position deviation may lead to a decline in welding quality, and further cause problems such as air leakage and short circuit, affecting the overall performance and service life of the product.

[0003] Traditional manual welding methods are difficult to meet these requirements. Manual welding depends on the skill level and experience of operators, and it is difficult to ensure that each welding can reach the ideal accuracy standard. It is easy to have welding gaps that are difficult to detect by the naked eye, resulting in serious problems such as leakage in the equipment produced during use.

[0004] To overcome the above drawbacks and improve welding quality and production efficiency, the application of automated welding technology (especially robot welding technology) is becoming increasingly widespread. Robots can achieve automatic positioning and welding of welded parts, reducing welding defects caused by human factors.

[0005] At the current stage, the robot welding method requires manual placement of the product to be welded on the welding fixture. After the product to be welded is placed on the welding fixture, it is necessary for an operator to hold a debugger and perform a simulated walk (i.e., the debugging process) along each predetermined welding position of the product to be welded. This debugging process aims to enable the robot to learn and record the welding path so that it can perform precise welding operations along these paths subsequently.

[0006] However, the inventor found that according to the current robot welding method, in the case of replacing the product, the actual position of the product may shift slightly due to various factors. This shift will cause a position deviation when the robot welds according to the preset path, thereby affecting the welding quality.

[0007] Therefore, in the prior art, every time a new product to be welded is replaced, the above-mentioned debugging process needs to be carried out again to ensure that the robot can accurately identify and weld to each predetermined welding position. In the process of mass production and manufacturing of products, the method of the prior art increases the welding debugging time and reduces the production efficiency. Summary of the Utility Model

[0029] Combined with the accompanying drawings in the embodiments of the present application, the technical solutions of the present application will be clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0030] Figure 1 shows the overall structure of the welding fixing device according to the embodiment of the present application. Referring to Figure 1 , the welding fixing device provided by the embodiment of the present application includes a main body 1, a product contact part 2, a clamping part 4, and a region adjusting part 5.

[0031] Referring to Figure 1 , the main body 1 is used to place the product to be welded. The product contact part 2 is arranged on the main body 1 and is perpendicular to the main body 1. As Figure 1 shown, a placement area 3 for accommodating the product to be welded is formed between the inner surface of the product contact part 2 and the main body 1. The placement area 3 is used to accommodate the product to be welded. When the product to be welded is placed in the placement area 3 by the staff, the product to be welded is in contact with the product contact part 2. And, the product to be welded is in contact with the inner surface of the product contact part 2.

[0032] Referring to Figure 1 , the clamping part 4 is connected to the outer surface of the product contact part 2 and is perpendicular to the product contact part 2. And the clamping part 4 is parallel to the main body 1. The clamping part 4 can control the product contact part 2 to move along the horizontal plane.

[0033] The clamping part 4 can push the product contact part 2 so that the product contact part 2 moves along the horizontal plane and towards the preset clamping direction. The preset clamping direction is the direction from the outer surface of the product contact part 2 to the inner surface. After the clamping part 4 pushes the product contact part 2, the product contact part 2 can clamp the product to be welded, so that the product to be welded can be fixed in the placement area 3 and fixed at the preset standard position in the placement area 3.

[0034] The preset standard position is preset and is used for placing the same kind of product to be welded.

[0035] Optionally, the clamping part 4 can also pull the product contact part 2 so that the product contact part 2 moves along the horizontal plane and towards the preset relaxation direction. The preset relaxation direction is opposite to the preset clamping direction and is the direction from the inner surface of the product contact part 2 to the outer surface.

[0036] After the product to be welded is welded, the clamping part 4 can pull the product contact part 2 so that the welded product can be released, facilitating the staff to take away the welded product.

[0037] Reference Figure 1 Figure 1 , the area adjustment part 5 is connected to the outer surface of the product contact part 2, is perpendicular to the product contact part 2, and is parallel to the main body 1. The area adjustment part 5 can push the product contact part 2 to drive the product contact part 2 to move on the main body 1 so as to adjust the range of the placement area 3.

[0038] Exemplarily, the staff places the product to be welded in the placement area 3 on the main body 1. After that, the staff can control the clamping part 4 to push the product contact part 2 so that the product contact part 2 clamps the product to be welded and fixes the product to be welded at a preset standard position in the placement area 3. Then the robot welds the product to be welded placed at the preset standard position. After the product to be welded is welded, the staff can control the clamping part 4 to pull the product contact part 2 so that the product contact part 2 releases the product to be welded, thereby facilitating the staff to take away the product to be welded.

[0039] After that, the staff places a new product to be welded in the placement area 3. When the type and size of the product to be welded do not change, the staff can directly place the new product to be welded in the placement area 3 without adjusting the area adjustment part 5, and continue to control the clamping part 4 to push the product contact part 2 so that the product to be welded is clamped by the product contact part 2 and fixed at the preset standard position. Then the robot performs welding.

[0040] When the size of the product to be welded changes, the staff can adjust the area adjustment part 5 to adjust the range of the placement area 3. After that, the staff places the new product to be welded in the adjusted placement area 3, and controls the clamping part 4 to push the product contact part 2 so that the new-sized product to be welded is clamped and fixed at the preset standard position corresponding to the product to be welded, and the robot performs welding.

[0041] In the embodiment of the present application, for products to be welded of the same size and type, each product to be welded will be fixed at a preset standard position for the robot to perform welding. In this way, it is not necessary to perform a robot debugging process every time the product to be welded is replaced, and only one debugging is required when products to be welded of each size are placed at the corresponding preset standard positions. Applying the present application to the mass production manufacturing process shortens the welding debugging time, improves the product welding efficiency, and thus improves the production efficiency.

[0042] According to some embodiments, continue to refer to Figure 1 Figure 1 , the product contact part 2 may specifically include a first fixed contact part 21, a second fixed contact part 22, a first adjustment contact part 23, and a second adjustment contact part 24.

[0043] Optionally, the first fixed contact portion 21, the second fixed contact portion 22, the first adjustment contact portion 23, and the second adjustment contact portion 24 may be in a plate-like structure.

[0044] According to an exemplary embodiment, referring to Figure 1 , the first fixed contact portion 21 is vertically fixed at a first preset position of the body 1. The second fixed contact portion 22 is vertically fixed at a second preset position of the body 1. The first adjustment contact portion 23 and the second adjustment contact portion 24 are respectively disposed perpendicular to the body 1 of the welding fixing device.

[0045] Optionally, the first adjustment contact portion 23 and the second adjustment contact portion 24 may be fixed to the body 1 or may be slidably connected to the body 1, which is not limited herein.

[0046] The first adjustment contact portion 23 and the first fixed contact portion 21 are disposed opposite and parallel to each other. The second fixed contact portion 22 and the second adjustment contact portion 24 are disposed opposite and parallel to each other. The region surrounded by the inner side surface 231 of the first adjustment contact portion, the inner side surface of the second adjustment contact portion 24, the inner surface of the first fixed contact portion 21, and the inner side surface of the second fixed contact portion 22 is the placement region 3.

[0047] That is, the placement region 3 is the region surrounded by the first side surface, the second side surface, the third side surface, and the fourth side surface. The first side surface is the inner side surface of the first fixed contact portion 21. The second side surface is the inner side surface of the second fixed contact portion 22. The third side surface is the inner side surface 231 of the first adjustment contact portion. The fourth side surface is the inner side surface of the second adjustment contact portion 24. Moreover, the first side surface and the third side surface are opposite surfaces. The second side surface and the fourth side surface are opposite surfaces.

[0048] That is, the respective side surfaces of the placement region 3 are, in clockwise order, the first side surface, the second side surface, the third side surface, and the fourth side surface.

[0049] According to some embodiments, referring to Figure 1 , the clamping portion 4 includes a first clamping portion 41 and a second clamping portion 42. The first clamping portion 41 is disposed perpendicular to the first adjustment contact portion 23 and is used to push the first adjustment contact portion 23. The second clamping portion 42 is disposed perpendicular to the second adjustment contact portion 24 and is used to push the second adjustment contact portion 24.

[0050] Referring to Figure 1 , one end of the first clamping portion 41 is fixedly connected to the outer side surface of the first adjustment contact portion 23, and pushes the first adjustment contact portion 23 to move in a first preset clamping direction. The first preset clamping direction is the direction in which the outer side surface of the first adjustment contact portion 23 perpendicularly points to the inner side surface, that is, the direction pointing to the first fixed contact portion 21.

[0051] When the first clamping part 41 pushes the first adjusting contact part 23, the first adjusting contact part 23 and the first fixed contact part 21 can clamp the product to be welded.

[0052] Referring to Figure 1 , one end of the second clamping part 42 is fixedly connected to the outer side surface of the second adjusting contact part 24. By pushing the second adjusting contact part 24 to move in the second preset clamping direction, the second preset clamping direction is the direction in which the outer side surface of the second adjusting contact part 24 perpendicularly points to the inner side surface, that is, the direction pointing to the second fixed contact part 22.

[0053] When the second clamping part 42 pushes the second adjusting contact part 24, the second adjusting contact part and the second fixed contact part 22 can clamp the product to be welded.

[0054] Under the pushing actions of the first clamping part 41 and the second clamping part 42 on the first adjusting contact part 23 and the second adjusting contact part 24 respectively, the product to be welded placed in the placement area 3 can be clamped by the first adjusting contact part 23, the second adjusting contact part 24, the first fixed contact part 21 and the second fixed contact part 22, so as to fix the position of the product to be welded, thereby improving the welding efficiency.

[0055] According to the exemplary embodiment, the first fixed contact part 21 and the second fixed contact part 22 are two boundaries fixedly arranged and immovable in the placement area 3, and the first adjusting contact part 23 and the second adjusting contact part 24 are respectively connected to the first clamping part 41 and the second clamping part 42. In this way, the product to be welded can be clamped by controlling the first adjusting contact part 23 and the second adjusting contact part 24.

[0056] Compared with the way that all four contact parts are connected with the clamping part 4, this setting method of the product contact part 2 can adjust the position of the product to be welded more accurately and fix the product to be welded at the preset standard position accurately.

[0057] Because, for the setting method in which the four contact parts are all connected with the clamping parts 4, when adjusting the welded product, it is necessary to push the four contact parts respectively, and in the process of pushing one of the contact parts, there will be a situation where the opposite contact part is pushed and deformed together. This will result in insufficient accuracy in adjusting the position of the product to be welded. In the method of the present application, when the product to be welded is fixed at the preset standard position, since the first fixed contact part 21 and the second fixed contact part 22 are fixed, only the first adjusting contact part 23 and the second adjusting contact part 24 need to be adjusted. And when pushing the first adjusting contact part 23 and the second adjusting contact part 24, the first fixed contact part 21 and the second fixed contact part 22 will not be pushed either. Therefore, it is beneficial to improve the accuracy of fixing the position of the product to be welded, thereby improving the welding effect.

[0058] According to some embodiments, referring to Figure 1 , the first clamping part 41 may specifically include at least two first telescopic units 411. The second clamping part 42 may include at least two second telescopic units 421. Figure 1 The structure in which the first clamping part 41 includes two first telescopic units 411 and the second clamping part 42 includes two second telescopic units 421 is shown.

[0059] The at least two first telescopic units 411 are respectively vertically fixed on the outer side surface of the first adjusting contact part 23. And the at least two first telescopic units 411 are located on the same horizontal line, and this horizontal line is parallel to the upper surface of the body 1. For example Figure 1 the two first telescopic units 411 provided in the welding fixing device in

[0060] The at least two first telescopic units 411 can be telescoped to control the first adjusting contact part 23 to move towards the placement area 3 or move away from the placement area 3.

[0061] For example, when the at least two first telescopic units 411 extend simultaneously, the first adjusting contact part 23 moves towards the first fixed contact part 21 to clamp the product to be welded between the first adjusting contact part 23 and the first fixed contact part 21. When the at least two first telescopic units 411 retract simultaneously, the first adjusting contact part 23 moves away from the first fixed contact part 21 to release the product to be welded between the first adjusting contact part 23 and the first fixed contact part 21.

[0062] The at least two second telescopic units 421 are respectively vertically fixed on the outer side surface of the second adjusting contact part 24. And the at least two second telescopic units 421 are located on the same horizontal line, and this horizontal line is parallel to the upper surface of the body 1. For example Figure 1The two second telescopic units 421 provided in the welding fixing device in

[0063] The at least two second telescopic units 421 can be telescoped to push the second adjusting contact part 24 to clamp the product to be welded between the second adjusting contact part 24 and the second fixed contact part 22, or pull the second adjusting contact part 24 to loosen the product to be welded between the second adjusting contact part 24 and the second fixed part.

[0064] For example, when the at least two second telescopic units 421 extend simultaneously, the second adjusting contact part 24 deforms towards the second fixed contact part 22 to clamp the product to be welded between the second adjusting contact part 24 and the second fixed contact part 22. When the at least two second telescopic units 421 retract simultaneously, the second adjusting contact part 24 deforms in a direction away from the second fixed contact part 22 to loosen the product to be welded between the second adjusting contact part 24 and the second fixed contact part 22.

[0065] Optionally, the first telescopic unit 411 and the second telescopic unit 421 can adopt a single-rod cylinder piston type telescopic mechanism. The single-rod cylinder piston telescopic structure can specifically be composed of a cylinder body and a piston rod. Taking the first telescopic unit 411 as an example for illustration.

[0066] The cylinder body serves as the main body part for bearing and guiding, and is responsible for connecting the external air supply system or pressure source. The piston rod is a motion execution element, one end of which is fixedly connected to the outer surface of the first adjusting contact part 23, and the other end of the piston rod is slidably matched with the inside of the cylinder body through structures such as seals.

[0067] The external air supply system can input or release compressed gas into the cylinder body. Due to the change in the gas pressure inside the cylinder body, the piston rod can perform linear telescopic motion inside the cylinder body, thereby pushing the first adjusting contact part 23 or pulling the first adjusting contact part 23.

[0068] In the embodiment of the present application, the first clamping part 41 adopts at least two first telescopic units 411 and the second clamping part 42 adopts at least two first telescopic units 411, which can prevent the first adjusting contact part 23 and the second adjusting contact part 24 from rotating when pushing and pulling the first adjusting contact part 23 and the second adjusting contact part 24, so that the first adjusting contact part 23 and the second adjusting contact part 24 can deform along a direction parallel to the body 1 to stably clamp the product to be welded.

[0069] According to some embodiments, the area adjusting part 5 can include a first area adjusting part 5 and / or a second area adjusting part 5.

[0070] Refer to Figure 1 and Figure 2, in a possible implementation, the area adjusting part 5 includes a first area adjusting part 5. A through hole 8 is provided on the body 1. The first adjusting contact part 23 is located in the through hole 8. The second adjusting contact part 24 is fixed on the body 1. The first area adjusting part 5 is fixed on the body 1. And the first area adjusting part 5 is perpendicular to the first adjusting contact part 23 and is connected to the outer side surface of the first adjusting contact part 23.

[0071] The first area adjusting part 5 can push or pull the first adjusting contact part 23, so that the first adjusting contact part 23 can move towards the first fixed contact part 21 or move away from the first fixed contact part 21, so as to reduce the longitudinal distance of the placement area 3 or increase the longitudinal distance of the placement area 3, thereby reducing the range of the placement area 3 or expanding the range of the placement area 3. The longitudinal distance is the distance between the first adjusting contact part 23 and the first fixed contact part 21.

[0072] In another possible implementation, the area adjusting part 5 includes a second area adjusting part 5. The second adjusting contact part 24 is located in the through hole 8. The first adjusting contact part 23 can be fixed on the body 1. The second area adjusting part 5 is fixed on the body 1. And the second area adjusting part 5 is perpendicular to the second adjusting contact part 24 and is connected to the outer side surface of the second adjusting contact part 24. The second area adjusting part 5 can push or pull the second adjusting contact part 24, so that the second adjusting contact part 24 can move towards the second fixed contact part 22 or move away from the second fixed contact part 22, so as to reduce the lateral distance of the placement area 3 or increase the lateral distance of the placement area 3. The lateral distance is the distance between the second adjusting contact part 24 and the second fixed contact part 22.

[0073] In still another possible implementation, the area adjusting part 5 can include the first area adjusting part 5 and the second area adjusting part 5. In this case, both the first adjusting contact part 23 and the second adjusting contact part 24 are located in the through hole 8. The longitudinal distance of the placement area 3 is adjusted by the first area adjusting part 5, and the lateral distance of the placement area 3 is adjusted by the second area adjusting part 5, so that under the combined action of the first area adjusting part 5 and the second area adjusting part 5, the range of the placement area 3 is adjusted.

[0074] According to some embodiments, the first area adjusting part 5 includes a first connecting part 51 and a first telescopic part 52. The second area adjusting part 5 can include a second connecting part and a second telescopic part.

[0075] According to the exemplary embodiment, refer to Figure 1, one end of the first connecting portion 51 is connected to the other end of the first clamping portion 41. The other end of the first clamping portion 41 is the end of the first clamping portion 41 that is not connected to the first adjusting contact portion 23, that is, the end far from the first adjusting contact portion 23.

[0076] The other end of the first connecting portion 51 is fixedly connected to the first telescopic portion 52. The first telescopic portion 52 can be telescoped in a direction parallel to the surface of the body 1 to drive the first connecting portion 51 to move back and forth in a straight line.

[0077] When the first telescopic portion 52 extends, the first connecting portion 51 is pushed, thereby driving the first clamping portion 41 and the first adjusting contact portion 23 to move in the direction of the first fixed contact portion 21. When the first telescopic portion 52 retracts, the first connecting portion 51 is pulled by the first telescopic portion 52, thereby driving the first clamping portion 41 and the first adjusting contact portion 23 to move away from the first fixed contact portion 21.

[0078] In this way, under the action of the first telescopic portion 52 and the first connecting portion 51, the movement of the first adjusting contact portion 23 can be controlled to adjust the distance between the first adjusting contact portion 23 and the first fixed contact portion 21, thereby adjusting the range of the placement area 3, so that the welding fixing device of the present application can adapt to welded products of different sizes.

[0079] Similarly, for the second area adjusting portion 5, one end of the second connecting portion is connected to the other end of the second clamping portion 42. That is, one end of the second connecting portion is connected to the end of the second clamping portion 42 that is not connected to the second adjusting contact portion 24. The other end of the second connecting portion is fixedly connected to the second telescopic portion.

[0080] The second telescopic portion can be telescoped in a direction parallel to the surface of the body 1 to drive the second connecting portion to move back and forth in a straight line. That is, the second telescopic portion can push the second connecting portion to drive the second clamping portion 42 and the second adjusting contact portion 24 to move in the direction of the second fixed contact portion 22. And the second telescopic portion can also pull the second connecting portion to drive the second clamping portion 42 and the second adjusting contact portion 24 to move away from the second fixed contact portion 22, thereby adjusting the range of the placement area 3, so that the welding fixing device of the present application can adapt to welded products of different sizes.

[0081] Optionally, the first telescopic part 52 may specifically be a pneumatic or hydraulic telescopic device combining a single piston design and guide rods on both sides. For example, the first telescopic part 52 may specifically be composed of a cylinder, a central piston, and two side rods respectively located on both sides of the central piston. The piston and the two side rods are respectively used to apply the same acting force to three different positions on the first connecting part 52. For example, the first telescopic part 52 may simultaneously use the single piston and the two side rods to apply the same-direction and same-magnitude acting forces to three different positions of the first connecting part 51, so as to drive the first connecting part 51 to perform a linear motion. In this way, when the first telescopic part 52 extends (or contracts), it can push (or pull) the first connecting part 51 along a straight line, and further drive the first adjusting contact part 23 to move along a straight line, thereby reducing the probability that the first adjusting contact part 23 rotates when driving the first adjusting contact part 23 to move.

[0082] Optionally, the structure of the second telescopic part may be the same as that of the first telescopic part 52, and will not be elaborated here.

[0083] According to some embodiments, referring to Figure 1 and Figure 2 , the welding fixing device may further include a bottom surface contact part 6 and a jacking part 7.

[0084] The bottom surface contact part 6 is disposed on the bottom surface of the placement area 3.

[0085] The bottom surface contact part 6 is disposed in the through hole 8. The top surface of the bottom surface contact part 6 is used to contact the product to be welded to carry the product to be welded.

[0086] The bottom surface of the bottom surface contact part 6 is fixedly connected to the jacking part 7. The jacking part 7 can push the bottom surface contact part 6 upward or pull the bottom surface contact part 6 downward, so that the bottom surface contact part 6 can move upward or downward.

[0087] Exemplarily, after completing the welding of the product to be welded, the jacking part 7 can, under the control of the staff, push the bottom surface contact part 6 upward, so that the bottom surface contact part 6 moves upward to eject the welded product carried by the bottom surface contact part 6. In this way, after completing the welding of the product to be welded, it is convenient for the staff to take out the welded product, improving the convenience of the staff.

[0088] Optionally, the structure of the jacking part 7 may also be the same as that of the above-mentioned first telescopic part 52, and will not be elaborated here.

[0089] Based on the above embodiments, an example is provided in the embodiments of the present application to illustrate the working process of welding a product using the welding fixing device.

[0090] The staff connect the gas source to each telescopic unit and each telescopic part of the welding fixing device. Then, the staff can place the product to be welded with the first preset size in the placement area 3 of the welding fixing device. Then, the staff can press the button to trigger the actions of the first telescopic unit 411 and the second telescopic unit 421, so that the first telescopic unit 411 and the second telescopic unit 421 push the first adjustment contact part 23 and the second adjustment contact part 24 to clamp the product to be welded at the preset standard position in the placement area 3.

[0091] Then the robot can weld the product to be welded in the preset standard position to obtain the welded product.

[0092] After welding is completed, the staff can press the button to trigger the actions of the first telescopic unit 411 and the second telescopic unit 421, so that the first telescopic unit 411 and the second telescopic unit 421 retract to release the welded product in the preset standard position.

[0093] Then, the staff can press the button to trigger the lifting unit, so that the lifting unit pushes the bottom contact part 6. The welded product is pushed out. The staff can then remove the welded product.

[0094] Then, when welding the product to be welded with the second preset size, the staff can press the button to trigger the area adjustment part 5 to work. When the second preset size is larger than the first preset size, the area adjustment part 5 can pull the first adjustment contact part 23 (and / or the second adjustment contact part 24) under the control of the staff to expand the range of the placement area 3.

[0095] Then the staff can place the product to be welded with the second preset size in the expanded placement area 3. Then, the staff can control the first telescopic unit 411 and the second telescopic unit 421 to push the first adjustment contact part 23 and the second adjustment contact part 24 to clamp the product to be welded with the second preset size at the preset standard position in the placement area 3, so that the robot can weld the product to be welded.

[0096] It should be noted that the staff can also control the area adjustment part 5 to clamp the product to be welded placed in the placement area 3, which is not limited here.

[0097] It should be noted that the staff can also fine-tune the relative positions between the cylinders and the piston rods of the first telescopic unit 411 and the second telescopic unit 421, so as to fine-tune the position of the first adjustment contact part 23 connected to the first telescopic unit 411 and the position of the second adjustment contact part 24 connected to the second telescopic unit 421. That is to say, the staff can also fine-tune the relative positions between the cylinders and the piston rods of the first telescopic unit 411 and the second telescopic unit 421 to adjust the range of the placement area 3 to adapt to welded products of different sizes.

[0098] Finally, it should be noted that the above are only the preferred embodiments of the present application and are not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions of the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
