[0027] In order to further understand the application content, characteristics and effects of the present application, the following examples are given, and the detailed description is as follows with reference to the accompanying drawings.

[0028] Example one:

[0029] Referring to Figure 1 and Figure 2 , Figure 1 is a structure diagram of the switchable suction mechanism in example one, Figure 2 is a structure diagram of the suction assembly in example one, the switchable suction mechanism in the embodiment includes a moving assembly 1, a suction assembly 2 and a latch assembly 3. The moving assembly 1 includes a moving frame body 11 and a mounting frame body 12, and the mounting frame body 12 is arranged on the moving frame body 11. The suction assembly 2 includes a suction frame body 21 and a suction member 22, and the suction member 22 is arranged on the suction frame body 21. The suction frame body 21 has a clamping groove structure 2111, which is matched with the mounting frame body 12. The mounting frame body 12 is embedded in the clamping groove structure 2111, so that the suction frame body 21 is clamped on the mounting frame body 12. The latch assembly 3 is fixed to the suction frame body 21 after passing through the mounting frame body 12.

[0030] The switchable suction mechanism in the embodiment is applied to carry components such as silica gel pads and insulating sheets during assembly of a battery module PACK. The suction frame part 21 has a clamping groove structure 2111, and the mounting frame part 12 is inserted into the clamping groove structure 2111, so that the suction frame part 21 is clamped and fixed to the mounting frame part 12. The switchable suction mechanism in the embodiment has a locking state and a disassembling state. In the locking state, the suction frame part 21 is clamped and fixed to the mounting frame part 12, and the latch assembly 3 is fixed to the suction frame part 21 after passing through the mounting frame part 12, so that the suction frame part 21 is fixedly connected to the mounting frame part 12. At this time, the suction and carrying operation can be performed. In the disassembling state, the latch assembly 3 is pulled out, and the suction frame part 21 and the suction accessory 22 are moved to move the mounting frame part 12 away from the clamping groove structure 2111, so that the suction frame part 21 and the mounting frame part 12 are separated. When different types of components need to be suctioned and carried, only the suction assembly 2 with the suction accessory 22 suitable for the components to be suctioned and carried needs to be replaced, without the need to completely replace the entire suction mechanism, thereby improving the versatility of the equipment and reducing the design and production cost of the equipment. Specifically, the moving frame part 11 is a moving frame connected to a moving module. It can be understood that the moving module in the embodiment can drive the moving frame to move in XYZ three-axis directions, and the moving frame moves to drive the mounting frame part 12, the suction frame part 21 and the suction accessory 22 to move synchronously, so as to realize the suction and carrying of the components. The latch assembly 3 in the embodiment is a spring type self-locking drawbar, and of course a press type self-locking latch can also be used in other embodiments.

[0031] Reference is made again to Figure 2Preferably, the adsorption frame body 21 comprises a bottom plate 211, two side plates 212 respectively arranged at two side edges of the bottom plate 211 and facing each other, and two extension plates 213 respectively connected to one end of the two side plates 212 away from the bottom plate 211 and extending towards each other, the bottom plate 211, the two side plates 212 and the two extension plates 213 cooperatively form a clamping groove structure 2111, and the latch assembly 3 is fixed to the bottom plate 211 after passing through the mounting frame body 12. In specific application, the mounting frame body 12 is a mounting plate, the size and shape of the clamping groove structure 2111 are adapted to the mounting plate, the mounting plate can be completely inserted into the clamping groove structure 2111, so that the mounting frame body 12 and the adsorption frame body 21 cannot move relative to each other in the vertical direction, at this time the adsorption frame body 21 is clamped to the mounting frame body 12, and then the latch assembly 3 is inserted through the mounting frame body 12 and fixed to the bottom plate 211 from the gap between the two extension plates 213, so that the relative position of the adsorption frame body 21 and the mounting frame body 12 is fixed and cannot move relative to each other, the movement module drives the movement of the mounting frame body 12, the adsorption frame body 21 and the adsorption component 22 to move synchronously to carry out the adsorption and carrying of the components. When different types of components need to be adsorbed and carried, the latch assembly 3 is pulled out to release the fixed state of the adsorption frame body 21 and the mounting frame body 12, and then the adsorption frame body 21 is moved to pull out the mounting frame body 12 from the clamping groove structure 2111, so that the adsorption frame body 21 and the adsorption component 22 can be detached from the mounting frame body 12, at this time only the adsorption assembly 2 with the adsorption component 22 adapted to the components to be adsorbed and carried needs to be replaced, without the need to completely replace the entire suction mechanism, that is, without the need to replace the movement module, the movement frame body 11, the mounting frame body 12 and the latch assembly 3. It can be understood that the movement module, the movement frame body 11 and the mounting frame body 12 in the embodiment can be applied to the adsorption and carrying of all different types of components, when different types of components need to be adsorbed and carried, only the adsorption assembly 2 with the adsorption component 22 adapted to the components to be adsorbed and carried needs to be replaced, and through the arrangement of the clamping groove structure 2111 and the latch assembly 3, the difficulty of disassembling and replacing the adsorption frame body 21 is reduced, so as to quickly switch to meet the mixed production of multiple types of components to realize the compatible adsorption and carrying of multiple different components, reduce the design and production cost of the equipment, and improve the production efficiency.

[0032] Referring to Figure 3 , Figure 3The diagram below illustrates the structure of the moving component in Embodiment 1. Preferably, there are two pin components 3, spaced apart from each other on the mounting frame 12. Using two pin components 3 further enhances the stability of the relative positions of the adsorption frame 21 and the mounting frame 12, further improving the locking strength and preventing material displacement during adsorption and handling due to loosening of the adsorption frame 21, thus improving product quality. Of course, in other embodiments, the number of pin components 3 can be three, four, or more; the specific number can be set according to actual production needs and is not limited here.

[0033] Rereference Figure 2 Preferably, the adsorption assembly 2 further includes a lifting drive 23, which is located at the bottom of the adsorption frame 21. The adsorption component 22 is connected to the drive end of the lifting drive 23. Through the lifting drive 23, the moving module drives the moving frame 11 to move, causing the mounting frame 12, the adsorption frame 21, and the adsorption component 22 to move synchronously. When the adsorption component 22 moves above the component to be adsorbed, the lifting drive 23 drives the adsorption component 22 to descend and adhere to the component for adsorption. Then, the moving module drives the moving frame 11 to move, causing the mounting frame 12, the adsorption frame 21, and the adsorption component 22 to move synchronously, moving the adsorption component 22 and the adsorbed component into the battery module PACK, that is, above the preset position where the component needs to be assembled. The lifting drive 23 then drives the adsorption component 22 to descend, the adsorption component 22 stops adsorption, and the component is placed in the preset position to complete the assembly. Because the lifting drive component 23 has higher movement precision compared to large mobile modules, it can more accurately place components in preset positions, avoiding squeezing or collision between the adsorption component 22 and the battery module PACK, thus improving safety. Specifically, the lifting drive component 23 is a lifting drive cylinder, and in this embodiment, the component is an insulating sheet.

[0034] Rereference Figure 2 Preferably, the adsorption component 2 further includes an elastic buffer 24. One end of the elastic buffer 24 is connected to the driving end of the lifting drive 23, and the other end of the elastic buffer 24 is connected to the adsorption component 22. By providing the elastic buffer 24, during the descent of the adsorption component 22 driven by the lifting drive 23, the elastic buffer 24 acts as a buffer, preventing the adsorption component 22 from directly and rigidly squeezing or colliding with the battery module PACK, thereby preventing damage to the adsorption component 22 or the battery module PACK and improving safety.

[0035] Rereference Figure 2Preferably, the elastic buffer 24 includes a first plate 241, a second plate 242, guide posts 243, and elastic parts. The first plate 241 is connected to the driving end of the lifting drive 23. One end of the guide post 243 passes through the first plate 241, and the other end of the guide post 243 is connected to the second plate 242. The two ends of the elastic parts are respectively connected to the first plate 241 and the second plate 242. The adsorption member 22 is disposed at the bottom of the second plate 242. In specific applications, in this embodiment, there are four guide posts 243 and four elastic parts. The four guide posts 243 are connected in sequence to form a rectangle, and one end of each of the four guide posts 243 is provided with a limit block. One end of the guide post 243 passes through the guide hole of the first plate 241 and exits the upper surface of the first plate 241. The outer diameter of the limit block is larger than the diameter of the guide hole. The other ends of the four guide posts 243 are respectively connected to the second plate 242. The four elastic parts are respectively sleeved on the four guide posts 243, and the two ends of the four elastic parts are respectively connected to the first plate 241 and the second plate 242. It is understandable that when the lifting drive 23 drives the adsorption component 22 to descend until it is in contact with the battery module PACK, if the lifting drive 23 continues to drive the adsorption component 22 to descend, the adsorption component 22 and the second plate 242 will compress and deform the elastic part, that is, the second plate 242 gradually approaches the first plate 241. This can avoid the adsorption component 22 from directly and rigidly squeezing or colliding with the battery module PACK, thus playing a buffering role and improving safety performance. Specifically, in this embodiment, the elastic part is a spring, and the adsorption component 22 includes a vacuum pump, an adsorption pipe and a suction plate 221. The suction plate 221 has multiple adsorption through holes. One end of the adsorption through hole is connected to the adsorption pipe, and the other end of the adsorption through hole is opened at the bottom of the suction plate 221. The adsorption pipe is connected to the vacuum pump. It is understood that in this embodiment, only one suction plate 221 with a large bottom area is provided, which can be used to adsorb and transport large components such as insulating sheets. Of course, in other embodiments, it can also be used to adsorb and transport other components, which is not limited here.

[0036] Example 2:

[0037] Reference Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of the switchable suction mechanism in Embodiment 2. Figure 5This is a schematic diagram of the adsorption assembly in Embodiment 2. The difference between the switchable suction mechanism in this embodiment and Embodiment 1 is that there are multiple lifting drive components 23, elastic buffer components 24, and adsorption components 22. Multiple lifting drive components 23 are arranged side-by-side at the bottom of the adsorption frame 21. One end of each elastic buffer component 24 is connected to the drive end of the lifting drive component 23, and the other end of each elastic buffer component 24 is connected to the adsorption component 22. In practical application, there are two lifting drive components 23, elastic buffer components 24, and adsorption components 22 in this embodiment. Two lifting drive components 23 are arranged side-by-side at the bottom of the adsorption frame 21. One end of each elastic buffer component 24 is connected to the drive end of the two lifting drive components 23, and the other end of each elastic buffer component 24 is connected to the two adsorption components 22. It is understood that the adsorption component 22 in this embodiment includes a vacuum pump, an adsorption pipe, and a suction block 222. The suction block 222 has multiple adsorption through holes. One end of the adsorption through hole is connected to the adsorption pipe, and the other end of the adsorption through hole is located at the bottom of the suction block 222. The adsorption pipe is connected to the vacuum pump. The volume of the suction block 222 in this embodiment is smaller than that of the suction plate 221 in the first embodiment. However, this embodiment has two suction blocks 222 at the same time. That is, this embodiment can adsorb and transport two small components at the same time. Moreover, the two components can be adsorbed, transported, and installed at different positions of the battery module PACK, thereby improving production efficiency.

[0038] Rereference Figure 5 Preferably, the adsorption assembly 2 further includes multiple release elements 25, which are disposed on the elastic buffer 24. By providing the release elements 25, this embodiment can also be used to adsorb and transport adhesive components, such as silicone pads. When the silicone pad is adsorbed onto the suction block 222, due to its adhesive nature, the silicone pad will remain attached to the suction block 222 even if the vacuum pump stops working. The release elements 25 can act on the silicone pad, causing it to separate from the suction block 222. Specifically, each elastic buffer 24 is equipped with two release elements 25.

[0039] Rereference Figure 5Preferably, the demolding component 25 includes a demolding drive part 251 and a demolding pin 252. The demolding drive part 251 is disposed on the elastic buffer part 24. One end of the demolding pin 252 is connected to the drive end of the demolding drive part 251, and the other end of the demolding pin 252 extends away from the elastic buffer part 24. In specific applications, both sides of the silicone pad are adhesive. When the adsorption component 22 transports the silicone pad to the designated position of the battery module PACK, the lifting drive part 23 drives the adsorption component 22 to descend. The adsorption component 22 presses the silicone pad onto the designated position of the battery module PACK, that is, one side of the silicone pad is adhered to the designated position of the battery module PACK. The demolding drive part 251 drives the demolding pin 252 to descend and abut against the silicone pad, continuously pressing the silicone pad onto the designated position of the battery module PACK. At this time, the lifting drive part 23 drives the adsorption component 22 to rise, thereby separating the adsorption component 22 from the silicone pad. The silicone pad is adhered to the designated position of the battery module PACK by the adhesiveness of one side. Specifically, the demolding drive unit 251 is a miniature cylinder. Furthermore, the other end of the demolding pin 252 is covered with an anti-stick film; specifically, release paper can be used to cover the other end of the demolding pin 252. This reduces the adhesion between the other end of the demolding pin 252 and the silicone pad. The bottom of the suction block 222 is also covered with an anti-stick film. It should be noted that the suction component 22 in Embodiment 1 can be used to absorb and transport large components such as insulating sheets. However, if it is necessary to absorb and transport smaller components or transport multiple components simultaneously, simply disassemble the suction component 2 in Embodiment 1 and replace it with the suction component 2 in Embodiment 2. There is no need to replace the moving module, moving frame component 11, mounting frame component 12, and pin assembly 3.

[0040] In summary, since the adsorption frame 21 has a slot structure 2111, the mounting frame 12 can be inserted into the slot structure 2111 to fix the adsorption frame 21 to the mounting frame 12. With the setting of the pin assembly 3, the switchable suction mechanism in this embodiment has two states: a locked state and a disassembled state. In the locked state, the adsorption frame 21 is fixed to the mounting frame 12, and the pin assembly 3 passes through the mounting frame 12 and is fixed to the adsorption frame 21, so that the adsorption frame 21 and the mounting frame 12 are fixedly connected. At this time, adsorption and handling operations can be performed. In the disassembled state, the pin assembly 3 is pulled out, and the adsorption frame 21 and adsorption element 22 are moved so that the mounting frame 12 is away from the slot structure 2111. The adsorption frame 21 and the mounting frame 12 are separated. When different types of parts need to be adsorbed and transported, only the adsorption assembly 2 with an adsorption element 22 that is compatible with the required adsorption and transport parts needs to be replaced. It is not necessary to completely replace the entire suction mechanism, which improves the versatility of the equipment and reduces the equipment design and production costs. The design of the slot structure 2111 and the pin assembly 3 reduces the difficulty of disassembling and replacing the adsorption frame 21, thereby achieving rapid switching to meet the mixed production of various types of parts and realizing compatibility with the adsorption and transport of various different parts, reducing the equipment design and production costs and improving production efficiency.
