Description

Technical Field

[0001] The utility model belongs to the technical field of automated production, and in particular relates to a large foam-applying pressure-maintaining device. Background Art

[0002] In some electronic products, in order to improve the installation stability and overall usage stability of the internal battery components, foam is usually attached to the surface of the battery components. The foam can have flame retardant, buffering or anti-static effects on the battery components.

[0003] The prior art discloses a large foam pasting device, which can realize the automatic loading of large foam by setting a foam handling mechanism, and after the large foam is loaded, the foam handling mechanism is used to carry and unload the fixture used to carry the large foam. In actual application, it is found that the device is not suitable for the attachment operation of battery components that are clamped and positioned by a fixture, and the attachment effect is not good; and in order to avoid damage to the surface of the large foam, the foam handling mechanism is set to a vacuum suction method, and the size and weight of the carrier are relatively large. Therefore, the vacuum suction method is difficult to achieve a stable handling and unloading effect on the carrier, and manual intervention is often required, which not only affects the operation efficiency, but also increases the labor cost. Utility Model Content

[0004] In order to solve the shortcomings of the prior art, the utility model provides a large foam pressure-maintaining device, which realizes a fully automated attachment effect and improves the attachment quality, automates the unloading of large foam carriers, has high operation stability, improves operation efficiency and reduces labor costs.

[0005] The technical purpose to be achieved by the utility model is achieved through the following technical solutions:

[0006] The utility model provides a large foam sticking pressure-maintaining device, comprising a feeding mechanism, a first conveying mechanism, a paper tearing and attaching mechanism, a second conveying mechanism, a visual inspection mechanism, a conveying mechanism, an opening and closing clamping mechanism and a pressure-maintaining mechanism;

[0007] The conveying mechanism is provided with a clamp, and the opening and closing clamp mechanism and the pressure-maintaining mechanism are sequentially distributed along the conveying direction of the conveying mechanism;

[0008] The first transport mechanism operates between the feeding mechanism and the paper tearing and attaching mechanism, and the second transport mechanism operates between the paper tearing and attaching mechanism, the visual inspection mechanism and the opening and closing clamping mechanism;

[0009] The loading mechanism includes a loading conveying module, an upper support module, a unloading conveying module and a carrier fork module. The loading conveying module and the unloading module are arranged in parallel. The upper support module is located below the conveying end of the loading conveying module. The carrier fork module is located on the same side of the conveying end of the loading conveying module and the conveying front end of the unloading conveying module, and is used to move the carrier fork at the conveying end of the loading conveying module to the conveying front end of the unloading conveying module.

[0010] In some implementations, the carrier fork module includes a first traverse drive assembly, a second traverse drive assembly, and a fork block;

[0011] The fork block is connected to the driving end of the second transverse driving assembly, and the second transverse driving assembly is connected to the driving end of the first transverse driving assembly. The driving directions of the first transverse driving assembly and the second transverse driving assembly are in a vertical relationship. Under the joint action of the first transverse driving assembly and the second transverse driving assembly, the fork block shifts the carrier fork at the conveying end of the loading conveying module to the conveying front end of the unloading conveying module, thereby achieving a stable unloading effect of the carrier.

[0012] In some implementations, the clamp opening and closing mechanism includes a first mounting seat, a clamp opening drive module, and a clamp closing drive module;

[0013] The opening clamping drive module and the closing clamping drive module are both arranged on the first mounting seat, and the opening clamping drive module is located below the closing clamping drive module. The opening clamping drive module mainly acts on the lower shell of the clamp, while the closing clamping drive module mainly acts on the upper cover of the clamp. This layout relationship can cooperate with the structure of the traditional clamp to realize automated opening and closing operations.

[0014] In some implementations, the clamp opening drive module includes a third transverse driving assembly, a first connecting block and a plurality of pins, wherein the first connecting block is connected to the driving end of the third transverse driving assembly, and a plurality of pins are arranged on the first connecting block at intervals. Under the driving action of the third transverse driving assembly, the plurality of pins are extended out by the first connecting block and inserted into the lower shell of the clamp to achieve the clamp opening effect.

[0015] In some implementations, the clamping drive module includes a first driving cylinder and a plurality of clamping units. The first driving cylinder is obliquely arranged on the first mounting seat, and the plurality of clamping units are connected to the driving end of the first driving cylinder. The obliquely arranged first driving cylinder plays a role of oblique driving, and can better achieve the automatic clamping effect of the clamp.

[0016] In some implementations, the clamping unit includes a second mounting seat, a lifting buffer assembly and a roller, the lifting buffer assembly is arranged on the second mounting seat, and the roller is connected to the lifting buffer assembly. The lifting buffer assembly can buffer the contact between the roller and the upper cover of the clamp, thereby avoiding hard contact from damaging the clamp or affecting the positioning of the battery assembly inside the clamp.

[0017] In some implementations, the opening and closing clamping mechanism also includes a vacuum module, which is disposed on the first mounting seat and located between the opening clamping drive module and the closing clamping drive module. The vacuum module can achieve a vacuum positioning effect on the battery assembly in the clamp during the opening and closing operations.

[0018] In some implementations, the pressure-maintaining mechanism includes a first mounting frame, a first lifting drive assembly, and a pressure-maintaining module;

[0019] The first lifting drive assembly is arranged on the first mounting frame, and the pressure maintaining module is connected to the driving end of the first lifting drive assembly. Under the action of the first lifting drive assembly, the pressure maintaining module moves downward to maintain the pressure of the attached large foam to improve the attachment effect.

[0020] In some implementations, the pressure maintaining module includes a second connecting block and several pressure maintaining blocks, the upper end of the second connecting block is connected to the driving end of the first lifting drive assembly, and the several pressure maintaining blocks are connected to the lower end of the second connecting block through elastic parts. The elastic parts act as a buffer for the pressure maintaining blocks to avoid hard contact and damage to the battery assembly, thereby ensuring the operation quality.

[0021] In some implementations, a buffer is provided at the lower end of the pressure-maintaining block, so that the contact between the pressure-maintaining block and the battery assembly has a buffering effect to avoid damage to the battery assembly.

[0022] In summary, the utility model has at least the following benefits:

[0023] 1. The large foam pressure-maintaining device provided by the utility model is provided with an opening and closing clamping mechanism, which can automatically open and close the clamps that clamp and position the battery components, so that the device is suitable for the attachment of battery components that are clamped and positioned by the clamps. At the same time, a pressure-maintaining mechanism is provided to perform pressure-maintaining operations on the large foam after attachment, thereby improving the attachment quality.

[0024] 2.

[0043] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0044] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0045] Embodiment 1:

[0046] See also Figure 1-Figure 7 A large foam sticking and pressure-maintaining device is used to realize the automatic sticking and pressure-maintaining operation of large foam, including a feeding mechanism 100, a first conveying mechanism 200, a paper tearing and attaching mechanism 300, a second conveying mechanism 400, a visual inspection mechanism 500, a conveying mechanism 600, an opening and closing clamping mechanism 700 and a pressure-maintaining mechanism 800.

[0047] Among them, the feeding mechanism 100 is used for loading the large foam, the first conveying mechanism 200 is used to convey the large foam on the feeding mechanism 100, the paper tearing mechanism 300 is used to tear off the attached paper on the large foam, the second conveying mechanism 400 is used to convey the large foam after the attached paper is torn off, the visual inspection mechanism 500 performs position detection on the large foam, the conveying mechanism 600 conveys the clamp with the battery assembly clamped, the opening and closing clamp mechanism 700 performs opening and closing operations on the clamp, and the pressure maintaining mechanism 800 performs pressure maintaining operations on the large foam that has been attached.

[0048] For example, a clamp is transported on the conveying mechanism 600, and the opening and closing clamp mechanism 700 and the pressure-holding mechanism 800 are distributed in sequence along the conveying direction of the conveying mechanism 600. That is, the battery assembly that needs to be pasted with a large foam is clamped in the clamp, and the clamp is transported on the conveying mechanism 600. When the clamp is transported to the position of the opening and closing clamp mechanism 700, the opening and closing clamp mechanism 700 performs the opening clamping operation to cooperate with the large foam pasting operation. After the pasting is completed, the opening and closing clamp mechanism 700 continues to perform the closing clamping operation. Then, the clamp continues to be transported to the position of the pressure-holding mechanism 800 under the action of the conveying mechanism 600, and the pressure-holding mechanism 800 performs the pressure-holding operation.

[0049] The first transport mechanism 200 operates between the feeding mechanism 100 and the paper tearing and attaching mechanism 300, that is, the first transport mechanism 200 is used to transport the large foam at the position of the feeding mechanism 100 to the paper tearing and attaching mechanism 300, and the paper tearing and attaching mechanism 300 performs the paper tearing and attaching operation. The second transport mechanism 400 operates between the paper tearing and attaching mechanism 300, the visual inspection mechanism 500 and the opening and closing clamp mechanism 700. Similarly, the second transport mechanism 400 is used to transport the large foam that has been torn off the paper at the position of the paper tearing and attaching mechanism 300 to the position of the visual inspection mechanism 500 for position information detection, so as to feed back to the second transport mechanism 400 for position correction. Then, the second transport mechanism 400 attaches the large foam to the battery assembly in the clamp at the position of the corresponding opening and closing clamp mechanism 700 on the conveying mechanism 600.

[0050] refer to Figure 2 and Figure 3 The loading mechanism 100 includes a loading conveying module 110 , an upper support module 120 , a unloading conveying module 130 and a carrier fork module 140 .

[0051] The loading and conveying module 110 is used to load and convey the carrier carrying large foam, and the upper support module 120 is used to lift the carrier that has been transported to the loading and conveying module 110 to ensure that the loading height of the large foam each time, that is, the loading position is the same. The unloading conveying module 130 is used to unload the carrier in an empty state, and the carrier fork module 140 is used to move the carrier fork in an empty state on the loading and conveying module 110 to the unloading conveying module 130 for automatic unloading.

[0052] The loading conveying module 110 and the unloading conveying module 130 are arranged in parallel. It is understandable that the conveying direction of the loading conveying module 110 is opposite to that of the unloading conveying module 130, so as to facilitate the fork of the carrier located at the conveying end of the loading conveying module 110 to the conveying front end of the unloading conveying module 130 for unloading. The upper support module 120 is located below the conveying end of the loading conveying module 110. When the carrier carrying the large foam is conveyed to its conveying end on the loading conveying module 110, it is the loading position of the large foam. Through the upper support function of the upper support module 120, it can be ensured that all the large foams on the carrier are located at the same height of the loading position. The carrier fork module 140 is located on the same side of the conveying end of the loading conveying module 110 and the conveying front end of the unloading conveying module 130. When the carrier located at the conveying end of the loading conveying module 110 is in an unloaded state, the carrier is moved laterally to the conveying front end of the unloading conveying module 130 through the fork action of the carrier fork module 140, and the unloading is transported through the unloading conveying module 130.

[0053] For example, about 60 large foams can be stacked on each carrier, and a partition is placed every 20 large foams to compress the large foams, so that each carrier can stack more large foams. After stacking the large foams on the carrier, the carrier is placed on the loading and conveying module 110 for conveying. When the carrier is conveyed to the conveying end of the loading and conveying module 110, the upper support module 120 located below the conveying end of the loading and conveying module 110 rises upward, that is, the carrier is lifted up, and then, under the action of other foam handling mechanisms, the large foams are moved away from the carrier for loading. After completing the handling of a large foam, the upper support module 120 rises to a preset height. It can be understood that the preset height is equivalent to the thickness of a large foam, so as to ensure that the height position of each handling of the foam handling mechanism is the same. In this way, when the carrier is in an unloaded state, the upper support module 120 moves downward and returns to the initial position. Subsequently, the carrier fork module 140 moves the unloaded carrier fork located at the conveying end of the loading conveying module 110 to the conveying front end of the unloading conveying module 130, and the unloading conveying module 130 automatically conveys and unloads the carrier.

[0054] By setting up the carrier fork module 140, the carrier transverse shift fork at the conveying end of the loading conveying module 110 is moved to the conveying front end of the unloading conveying module 130. Compared with the existing carrier unloading method, it has the advantage of high operation stability and does not require manual intervention, thereby effectively improving operation efficiency and reducing labor costs.

[0055] Embodiment 2:

[0056] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the vehicle fork module 140 of the utility model, see Figure 8 .

[0057] The carrier fork module 140 includes a first transverse driving component 141, a second transverse driving component 142 and a fork block 143; the fork block 143 is connected to the driving end of the second transverse driving component 142, and the second transverse driving component 142 is connected to the driving end of the first transverse driving component 141. The driving directions of the first transverse driving component 141 and the second transverse driving component 142 are in a vertical relationship. Under the joint action of the first transverse driving component 141 and the second transverse driving component 142, the fork block 143 moves the carrier fork at the conveying end of the loading conveying module 110 to the conveying front end of the unloading conveying module 130, thereby achieving a stable unloading effect of the carrier.

[0058] It can be understood that the first transverse driving component 141 is distributed between the conveying end of the loading conveying module 110 and the conveying front end of the unloading conveying module 130, and is used to drive the fork block 143 to move between the conveying end of the loading conveying module 110 and the conveying front end of the unloading conveying module 130, and the second transverse driving component 142 is used to drive the fork block 143 to move closer to or away from the carrier, and to establish a contact connection or disconnection relationship with the carrier.

[0059] Embodiment 3:

[0060] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the opening and closing clamp mechanism 700 of the utility model, see Fig. 9 .

[0061] The opening and closing clamping mechanism 700 includes a first mounting seat 710, an opening clamping drive module 720 and a closing clamping drive module 730; the opening clamping drive module 720 and the closing clamping drive module 730 are both arranged on the first mounting seat 710, and the opening clamping drive module 720 is located below the closing clamping drive module 730. The opening clamping drive module 720 mainly acts on the lower shell of the clamp, while the closing clamping drive module 730 mainly acts on the upper cover of the clamp. This layout relationship can cooperate with the structure of the traditional clamp to realize automated opening and closing operations.

[0062] Specifically, the clamp opening drive module 720 includes a third transverse driving component 721, a first connecting block 722 and a plurality of latches 723. The first connecting block 722 is connected to the driving end of the third transverse driving component 721. The plurality of latches 723 are arranged on the first connecting block 722 at intervals. Under the driving action of the third transverse driving component 721, the plurality of latches 723 are extended out by the first connecting block 722 and inserted into the lower shell of the clamp to achieve the effect of clamping.

[0063] It should be noted that, in this embodiment, the attachment and pressure-maintaining operation of the large foam is carried out, so the size of the corresponding battery assembly and the clamp used to clamp the battery assembly is also relatively large. For this reason, the lower shell of the clamp will be provided with multiple snap-fit ​​structures to ensure the clamping effect of the clamp. It is known that between the lower shell and the upper cover of the traditional clamp, there will be an elastic member, a buckle and a slot. Under the elastic force of the elastic member, the buckle is engaged in the slot, so that the lower shell and the upper cover of the clamp are in a clamped state; when the buckle is subjected to an external force and squeezes the elastic member, the buckle will be separated from the slot, so that the lower shell and the upper cover of the clamp are in an open state. Therefore, in this embodiment, by correspondingly setting a number of latches 723, the number of latches 723 can be extended in a linkage manner under the action of the first connecting block 722, pushing the buckle to squeeze the elastic member, so that the clamp is in an open state, and an automatic open clamping effect is achieved.

[0064] In some embodiments, the clamping drive module 730 includes a first driving cylinder 731 and a plurality of clamping units 732. The first driving cylinder 731 is obliquely arranged on the first mounting base 710. The plurality of clamping units 732 are connected to the driving end of the first driving cylinder 731. The obliquely arranged first driving cylinder 731 plays a role of oblique driving, which can better achieve the automatic clamping effect of the clamp.

[0065] Specifically, the clamping unit 732 includes a second mounting seat 7321, a lifting buffer assembly 7322 and a roller 7323. The lifting buffer assembly 7322 is arranged on the second mounting seat 7321, and the roller 7323 is connected to the lifting buffer assembly 7322. The setting of the lifting buffer assembly 7322 can buffer the contact between the roller 7323 and the upper cover of the clamp, thereby avoiding hard contact from damaging the clamp or affecting the positioning of the battery assembly inside the clamp.

[0066] In this embodiment, there is no specific limitation on the number of latches 723 and clamping units 732, and they can be adjusted according to the actual structure of the clamp.

[0067] In some embodiments, the opening and closing clamping mechanism 700 also includes a vacuum module 740, which is disposed on the first mounting seat 710 and located between the opening clamping drive module 720 and the closing clamping drive module 730. The vacuum module 740 can achieve a vacuum positioning effect on the battery assembly in the clamp during the opening and closing operations.

[0068] It can be known that a vacuum suction hole is opened in the lower shell of the clamp, and the vacuum suction hole can be connected to the vacuum module 740. The vacuum module 740 generates a vacuum effect, so that during the opening and closing operations, the positioning effect of the battery assembly in the clamp is increased, thereby improving the accuracy of the large foam attachment operation.

[0069] Embodiment 4:

[0070] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the pressure-maintaining mechanism 800 of the utility model, see Fig.10 .

[0071] The pressure-maintaining mechanism 800 includes a first mounting frame 810, a first lifting drive assembly 820 and a pressure-maintaining module 830; the first lifting drive assembly 820 is arranged on the first mounting frame 810, and the pressure-maintaining module 830 is connected to the driving end of the first lifting drive assembly 820. Under the action of the first lifting drive assembly 820, the pressure-maintaining module 830 moves downward to maintain the pressure on the large foam that has been attached, thereby improving the attachment effect.

[0072] Specifically, the pressure maintaining module 830 includes a second connecting block 831 and a plurality of pressure maintaining blocks 832. The upper end of the second connecting block 831 is connected to the driving end of the first lifting drive assembly 820. The plurality of pressure maintaining blocks 832 are connected to the lower end of the second connecting block 831 through elastic parts. The elastic parts act as a buffer for the pressure maintaining blocks 832 to avoid damage to the battery assembly due to hard contact, thereby ensuring the operation quality.

[0073] Among them, a buffer member 833 is provided at the lower end of the pressure maintaining block 832. The buffer member 833 can be made of a material with a certain elasticity such as resin, so that the contact between the pressure maintaining block 832 and the battery assembly has a buffering effect to avoid damage to the battery assembly.

[0074] The utility model provides a large foam pressure-maintaining device, which is provided with an opening and closing clamping mechanism, and can automatically open and close the clamp on which the battery component is clamped and positioned, so that the device is suitable for the attachment operation of the battery component that is clamped and positioned by the clamp. At the same time, a pressure-maintaining mechanism is provided to perform pressure-maintaining operation on the large foam after attachment, thereby improving the attachment quality; a carrier fork module is provided to move the carrier fork at the conveying end of the loading and conveying module to the conveying front end of the unloading and conveying module, thereby realizing automatic unloading of the carrier. Compared with the existing carrier that adopts the method of carrying and unloading, it has the advantage of high operation stability, does not require manual intervention, and effectively improves the operation efficiency and reduces the labor cost.

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
