Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0065] The following describes in detail, with reference to the accompanying drawings, the surface-shaped small part welding positioning platform of this utility model.

[0066] Reference Figures 1 to 6As shown, the surface-shaped small part welding positioning platform provided according to the embodiment of this utility model includes a base 10, a negative pressure seat 20, a flat small part positioning seat 30, and a product positioning seat 40.

[0067] The base 10 serves as a base for mounting the negative pressure seat 20, the flat material positioning seat 30, and the product positioning seat 40 inside the welding equipment, so as to facilitate the positioning of the product and the flat material through the aforementioned components.

[0068] The negative pressure seat 20 includes a mounting plate 21, a support plate 22, and a plurality of negative pressure suction heads 23. The mounting plate 21 is disposed on the base 10, and the support plate 22 is disposed on the mounting plate 21. The upper surface of the support plate 22 is provided with a plurality of protrusions 221, and the upper surface of each of the plurality of protrusions 221 is provided with positioning mounting holes 2211 extending into the support plate 22. The plurality of negative pressure suction heads 23 are respectively disposed in the plurality of positioning mounting holes 2211 for suctioning products.

[0069] The negative pressure seat 20 can generate negative pressure, which can be used to attract and fix the product. Specifically, the negative pressure seat 20 includes a mounting plate 21, a support plate 22, and multiple negative pressure suction heads 23. The mounting plate 21 and the support plate 22 are stacked on top of each other. The mounting plate 21 is set on the base 10. The support plate 22 is smaller than the mounting plate 21 and is set on the upper surface of the mounting plate 21 for mounting multiple negative pressure suction heads 23. Under the action of the negative pressure mechanism, the multiple negative pressure suction heads 23 can generate negative pressure, thereby attracting and fixing the product on the support plate 22, so that the product will not shift, which is convenient for subsequent welding.

[0070] The planar small material positioning seat 30 is disposed on the mounting plate 21 and is used to position and fix the small material; the product positioning seat 40 is disposed on the mounting plate 21 and is used to position the product so that when the product is adsorbed on the support plate 22, the planar small material positioning seat 30 is located in the welding area of ​​the product.

[0071] In other words, the product positioning seat 40 and the flat part positioning seat 30 respectively position and fix the product and the flat part, so that the product can be accurately attracted and fixed on the support table. Furthermore, under the positioning action of the flat part, the flat part can be positioned and fixed in the welding area of ​​the product. In this way, even during subsequent welding, the part and the product remain fixed and will not shift due to factors such as thermal stress or mechanical vibration, thus ensuring the accuracy of welding.

[0072] More specifically, in use, under the drive of a robotic arm, the motherboard of an electronic device such as a mobile phone or tablet can be moved above the support plate 22. Guided by the positioning seat 40, the product is moved to the upper surface of the support plate 22, and then clamped and fixed by multiple negative pressure suction heads 23, preventing the product from shifting. At this time, the flat material is located in the welding area on the product. Further, the robotic arm moves the flat material to the flat material positioning seat 30. Under the positioning and fixing action of the flat material positioning seat 30, the flat material can accurately correspond to the welding area on the product and remain fixed to the product. Finally, the flat material is welded to the product by the welding equipment, thus completing the welding of the product and the flat material. In the above process, the product positioning seat 40 and the flat part positioning seat 30 can quickly and conveniently position the product and the flat part accurately. During welding, the product and the flat part remain relatively fixed and will not be displaced. This makes welding very convenient and ensures that the flat part is accurately welded onto the product, thus ensuring welding quality.

[0073] The planar small part welding positioning platform provided by this utility model has a simple structure and is easy to use. It can position and fix small parts to prevent them from shifting during the welding process and affecting the welding effect.

[0074] Advantageously, in one embodiment of the present invention, the base 10 includes a base plate 11 and a plurality of fixing blocks 12; each of the four corners of the base plate 11 is provided with a first fixing hole 111, and the base plate 11 is installed inside the device by a first fixing member 113 passing through the first fixing hole 111; the plurality of fixing blocks 12 are respectively provided at the four corners of the base plate 11 and adjacent to the first fixing hole 111, for installing the mounting plate 21.

[0075] Preferably, a first positioning hole 112 is provided on the base plate 11 between two adjacent first fixing holes 111, and the first positioning hole 112 is inserted into and engaged with the first positioning rod inside the equipment.

[0076] Thus, when assembling the base 10, the first positioning hole 112 on the base plate 11 and the first positioning rod inside the equipment can be inserted and engaged to position the base plate 11, thereby aligning the first fixing hole 111 on the base plate 11 with the fixing hole on the equipment. Furthermore, the first fixing member 113 can be inserted and fixed into the first fixing hole 111 and the fixing hole on the equipment. In this way, the installation and fixing of the base 10 is completed, which is convenient, quick, and conducive to assembly.

[0077] Advantageously, in one embodiment of the present invention, the base plate 11 is provided with two hollow holes 114 in the middle.

[0078] By setting a perforated hole 114 in the middle of the base plate 11, the base plate 11 can be made into a frame structure. This can reduce the material consumption of the base plate 11, thereby saving costs and facilitating its use.

[0079] Advantageously, in another embodiment of the present invention, a negative pressure connector 211 is provided on the front side wall of the mounting plate 21, one end of the negative pressure connector 211 is connected to the negative pressure mechanism inside the equipment, and the other end is connected to the plurality of negative pressure suction heads 23.

[0080] The negative pressure connector 211 serves as a transition structure, connecting multiple negative pressure suction heads 23 to a negative pressure device. In this way, the negative pressure device can generate negative pressure in the negative pressure suction heads 23, thereby using multiple negative pressure suction heads 23 to firmly fix the product on the support plate 22, preventing the product from shifting and affecting the welding quality when welding small parts.

[0081] Advantageously, in some embodiments of the present invention, a plurality of clearance grooves 222 are provided on the left and right side walls of the support plate 22, and the product positioning seat 40 and the flat small material positioning seat 30 are both disposed in the clearance grooves 222.

[0082] Thus, the left and right side walls of the support plate 22 are recessed inward to form relief grooves 222, which can be used to position and install the product positioning seat 40 and the flat small part positioning seat 30, ensuring that the product positioning seat 40 and the flat small part positioning seat 30 are adapted to the structure of the product, thereby completing the positioning of the product and small parts, which is conducive to accurately welding the small parts onto the product.

[0083] Advantageously, in some embodiments of the present invention, the product positioning base 40 includes a positioning block 41 and a positioning post 42; the positioning block 41 is provided with a second fixing hole 411 and a second positioning hole 412, and the positioning block 41 is fixed to the mounting plate 21 by a second fixing member passing through the second fixing hole 411; the plurality of second positioning holes 412 are inserted into and cooperate with a plurality of second positioning rods on the mounting plate 21; the positioning post 42 is disposed on the positioning block 41 for positioning the product.

[0084] The positioning block 41 is used to mount the positioning post 42 on the mounting plate 21, so as to position the product through the positioning post 42. The positioning block 41 is provided with a second fixing hole 411 and a second positioning hole 412. The second positioning hole 412 can be inserted and engaged with the second positioning rod on the mounting plate 21 to position the positioning block 41, so that the second fixing hole 411 on the positioning block 41 corresponds to the fixing hole on the mounting plate 21. Furthermore, the second fixing member is inserted and fixed in the second fixing hole 411 and the fixing hole on the mounting plate 21. Thus, the installation and fixing of the product positioning seat 40 is completed, which is convenient, quick and easy and facilitates assembly.

[0085] Advantageously, in some other embodiments of the present invention, the outer diameter of the upper end of the positioning post 42 is smaller than the outer diameter of the lower end.

[0086] Thus, because the upper outer diameter of the positioning post 42 is small, it can play a certain guiding role for the product. That is, the upper end of the positioning post 42 can pass smoothly through the positioning hole on the product, thereby allowing the product to move down along the positioning post 42 to achieve product positioning, ensuring that the welding area on the product corresponds to the flat small material, so as to facilitate the subsequent welding of the small material.

[0087] Advantageously, in some other embodiments of the present invention, a boss 31 is provided in the middle of the planar small material positioning seat 30, and a positioning platform 311 is provided at one end of the boss 31. A negative pressure hole 3111 is provided on the positioning platform 311, and the negative pressure hole 3111 is connected to a negative pressure mechanism for attracting and fixing the small material. A third fixing hole 312 is provided at the other end of the boss 31, and the planar small material positioning seat 30 is installed on the mounting plate 21 by a third fixing member passing through the third fixing hole 312. A third positioning hole 32 is provided on both sides of the boss 31 on the planar small material positioning seat 30, and the third positioning hole 32 is inserted into and cooperates with the third positioning rod on the mounting plate 21.

[0088] Thus, even if the upper surface height of the positioning platform 311 at one end of the boss 31 is higher than the upper surface height of the boss 31, the positioning platform 311 can be used to support the flat material and connect it to the product. Under the action of the negative pressure mechanism, the negative pressure hole 3111 generates negative pressure to suck and fix the flat material, so that the flat material will not be displaced, which facilitates subsequent welding. The third fixing hole 312 at the other end of the boss 31 and the third positioning hole 32 on the flat material positioning seat 30 can make the flat material positioning seat 30 very convenient and quick to install on the mounting plate 21. During installation, the third positioning hole 32 on the flat material positioning seat 30 is inserted into the third positioning rod on the mounting plate 21 to make the third fixing hole 312 correspond to the fixing hole on the mounting plate 21. Then, it is locked and fixed by the third fastener. The assembly is simple and convenient, and the fixing effect is good.
