[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] An embodiment of the present utility model, as Figure 1 、 Figure 2 and Figure 4As shown, the bending device includes a main mounting module 2 fixedly mounted on the frame 1, and an upper mold and a lower mold 3 are arranged in the main mounting module 2, and the lower mold 3 includes a jig base plate 31 fixed on the main mounting plate 21 at the bottom of the main mounting module 2, and a product 32 is installed on the jig base plate 31, and the product includes a bottom shell, an upper cover and a PCBA. Side bending mechanisms 33 installed on the jig base plate 31 are arranged around the product 32. In this embodiment, six groups of side bending mechanisms 33 are provided. The main mounting module 2 applies a force to the side bending mechanisms 33 during the vertical movement to bend and squeeze the extended legs of the upper cover of the product 32 to achieve automatic alignment and automatic bending. An upper cover is provided on the top of the frame, and a negative pressure alarm system is installed in the upper cover. The negative pressure alarm mechanism is introduced to ensure the stability of the cover during the bending process, thereby improving the safety of the production process. The bending device disclosed in this application The equipment is suitable for bending automotive parts, such as body parts, engine parts, chassis parts, etc., automated production of electronic equipment housings and heat sinks, and manufacturing metal housings and internal structural parts for home appliances such as washing machines, refrigerators, and microwave ovens. Through precise positioning fixtures, the bottom shell and PCBA are more accurately aligned with the cover plate, reducing manual alignment errors. The improved upper mold fixture design and negative pressure adsorption technology effectively prevent glue dripping during the bending process, improving the appearance quality of the product. Automated operation reduces the number of times manual labor directly contacts the bending area, reduces the risk of work-related injuries, and improves overall operational safety. The automated bending process shortens the production cycle, increases the throughput of the production line, and thus improves overall production efficiency. The equipment design allows for quick adjustment to adapt to bending requirements of different sizes and shapes, improving production flexibility.

[0030] like Figure 2 and Figure 3As shown, the main mounting module 2 includes a main mounting plate 21 and a top plate 22 arranged opposite to each other in the vertical direction, and four pillars 23 are arranged between the two. An upper mold is movably installed on the pillar 23, and the upper mold includes a movable pressing mechanism 24.

The movable pressing mechanism 24 includes a movable plate 241, which is mounted on the pillar 23 through a linear bearing. An upper sliding pressure block 242 corresponding to the side bending mechanism 33 is provided at the bottom of the movable plate 241. The upper sliding pressure block 242 is fixed to the movable plate 241 by an adjusting screw assembly 243 installed on the side of the movable plate 241. A separation floating block 244 and a floating joint 245 are installed at the top center of the movable plate 241. The floating joint 245 is fixedly connected to the output end of the standard cylinder 26. The movable downward pressing mechanism and the upper shell adsorption mechanism constitute the upper mold, and the jig is the lower mold. After the operator presses the start button, the upper mold automatically moves down, closes the mold with the jig and completes the bending process. This automated operation reduces manual intervention and improves production efficiency and safety.

[0031] The upper shell adsorption mechanism 25 includes an adsorption mounting plate 251 connected to the bottom of the movable plate 241 through a mold spring 253. An upper cover adsorption plate 252 is fixedly installed on the surface of the adsorption mounting plate 251. A vacuum suction cup 254 is provided at the bottom of the upper cover adsorption plate 252. The cover plate is fixed to the upper shell adsorption mechanism by vacuum adsorption. The negative pressure alarm system ensures the stability of the adsorption. This improvement improves the stability of the cover plate during the bending process and reduces the safety risks during operation.

[0032] like Figure 5 As shown, the bottom of the product 32 is provided with a lower support plate 34 fixed on the jig base plate 31, and a capacitive proximity switch 35 is installed at the center of the top of the lower support plate 34. Rigid positioning columns 36 for supporting the product 32 are provided on the left and right sides of the product 32, and the rigid positioning columns 36 are fixed on the jig base plate 31. The circular ring structure around the product 32 is sleeved on the top of the rigid positioning columns 36, corresponding one to one. The positioning jig composed of the lower support plate and the rigid positioning columns can be accurately placed on the jig after the gluing operation is completed on the bottom shell and PCBA of the product, ensuring the correct positioning of the components, improving the accuracy of the alignment, and reducing the possibility of glue dripping.

[0033] like Figure 6As shown, the side bending mechanism 33 includes a guide base block 331 fixed on the jig bottom plate 31, a base 332 is slidably installed inside the guide base block 331, a spring mounting plate 333 is provided on the side of the guide base block 331 away from the jig, a mold spring is mounted on the outer side of the spring mounting plate 333 by screws, the end of the screw passes through the spring mounting plate 333 and is connected to the base 332, a groove for mounting a clamping block 335 is provided on the top of the base 332, a spring limiting plate is provided in the groove, the clamping block 335 and the spring limiting plate are connected by a compression spring, a side pushing block 336 is movably installed on the base 332 below the clamping block 335, the inclined surface of the top of the base 332 corresponds one to one to the inclined surface of the upper sliding pressure block 242, and the guide base blocks on both sides of the base 332 A reset block 334 is provided at the top of 331, and a first rotating shaft 337 is provided in the side push block 336, which is clamped between the reset block 334 and the guide base block 331. The side push block 336 is movably clamped in the base 332, and the side edge of the guide base block 331 close to the side push block 336 is tilted upward. The automatic downward and upward movement mechanism of the upper shell adsorption mechanism reduces the steps of manual operation, improves production efficiency, and reduces safety risks during operation. The simplified operating process makes it easier for operators to master the use of the equipment, reduces training time and cost, and automated control ensures the consistency of each bending process, improves the stability of product quality, reduces the physical labor of operators during the bending process, improves the working environment, and reduces labor intensity.

[0034] The center of the pressing block 335 is provided with a waist-shaped groove, and the waist-shaped groove is provided with a second rotating shaft 338 passing through the base 332. The pressing block 335 moves horizontally in the base 332. A gap is provided between the pressing block 335 and the side-pushing block 336. The upper sliding pressing block contacts the base during the descent process, and the applied pressure acts on the surface of the base to make the base move laterally toward the fixture. During the transverse movement, the pressing block contacts the side of the product and the compression spring is compressed to position the periphery of the product while avoiding crushing the product. The base continues to move laterally, and the first rotating shaft on the side-pushing block rolls along the top of the guide base block. Since the side-pushing block is clamped in the base, the clamping state is as follows Figure 5 As shown, the bearing outside the first rotating shaft gradually moves to the position where the edge of the guide base block is tilted upward, and is restricted by the reset block, as shown in FIG. Figure 7 As shown, the side thrust block deflects upward a short distance around the first rotation axis. Figure 8 The cover shown extends its legs for bending. The presence of the inclined section makes the bending angle slightly greater than 90°. After the upper sliding pressure block moves upward, the pressing block and the side push cutting block are reset, which also facilitates the demoulding and exit of the side push cutting block.

[0035] The working principle of this embodiment is as follows: the bottom shell and PCBA are positioned. First, the bottom shell and PCBA are installed and glued, and then accurately placed in the positioning fixture on the bottom side of the bending equipment. This ensures the accurate alignment of the bottom shell and PCBA, laying the foundation for subsequent bending work.

[0036] The cover is then fixed to the upper shell adsorption mechanism by vacuum adsorption. The negative pressure alarm system plays a monitoring role in this process to ensure that the cover is firmly adsorbed and prevent displacement during the bending process.

[0037] During the automatic bending process, the operator presses the start button to trigger the automatic bending sequence. The movable pressing mechanism then moves downward, closes the mold with the bottom shell on the lower mold, and completes the bending action. This process is fully automated and requires no human intervention, which improves efficiency and safety.

[0038] After the finished product is removed and the bending is completed, the movable downward pressure mechanism automatically moves upward to prepare for the next cycle. At this point, the operator can manually remove the finished product for subsequent processing or quality inspection. Although this step still requires manual operation, the automatic upward movement of the movable downward pressure mechanism has simplified the unloading process and improved overall production efficiency.
