Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of adhesive material pasting processing, in particular to a soft adhesive material positioning and pasting device. BACKGROUND

[0002] In the process of product production and processing, it is often necessary to paste soft adhesive materials such as functional adhesive tape and double-sided adhesive tape on certain specific areas of the product. The existing pasting methods generally include manual pasting and roller knife pasting. Manual pasting is low in efficiency and accuracy. Roller knife pasting refers to using a roller to press a section of adhesive tape onto a specific part and then using a cutter to cut the section of adhesive tape from the adhesive tape roll. This method improves the efficiency compared to manual pasting, but it is generally suitable for low-precision processing and is difficult to achieve precise positioning when facing small parts.

[0003] Patent application No. CN201610946267.9 discloses a pasting machine, which includes a rack, a material stripping mechanism for stripping and pasting materials, a carrier for placing the parts to be pasted, and a transfer device for transferring the pasting materials from the material stripping mechanism to the carrier. The material stripping mechanism, the transfer device, and the carrier are fixed on the rack. In use, the parts to be pasted are placed on the carrier by hand, the carrier is moved to the pasting station after pressing the button, the material stripping mechanism strips the pasting materials from the tape, the mechanical hand sucks the pasting materials, positions them through the engineering camera, and then pastes them from near to far in sequence. After completion, the tray is pushed back to the feeding station by the reset cylinder, and another tray enters, and the process is repeated. This technical solution improves the processing accuracy to some extent compared to the roller knife pasting method, but the processing process requires the mechanical hand to adsorb the pasting materials and then paste them on the specific parts of the parts to be pasted in sequence, which is low in efficiency during the reciprocating operation process. SUMMARY

[0004] To solve the above problems, the present application provides a soft adhesive material positioning and pasting device, which has high precision and processing efficiency when pasting adhesive on products, and can produce continuously, reducing manual operation.

[0005] To achieve the above purpose, the present application adopts the following technical solutions:

[0006] The application discloses a soft adhesive material positioning and pasting device, which comprises a rack, a material stripping mechanism for stripping soft adhesive material, a carrier mechanism for placing an object to be pasted, a cutting mechanism for cutting and pasting the soft adhesive material and a transfer mechanism for transferring the soft adhesive material to the cutting mechanism, wherein the material stripping mechanism, the carrier mechanism, the cutting mechanism and the transfer mechanism are fixedly installed on the rack; the carrier mechanism comprises a base and a receiving block movably installed on the base and used for placing the object to be pasted; the cutting mechanism comprises a positioning module and a cutting assembly, the positioning module forms a soft adhesive channel and a cutting channel in a first direction and a second direction perpendicular to each other, the soft adhesive channel and the cutting channel intersect with each other and a cutting die port is formed at the intersection, and the cutting assembly comprises a cutting pressure rod which is cooperatively installed with the cutting channel and a first power device which controls the cutting pressure rod to move in the cutting channel; the receiving block and the first power device are arranged at one side of a first port and one side of a second port of the cutting channel respectively, and an end of the cutting pressure rod close to the receiving block can extend out of the first port of the cutting channel.

[0007] The basic processing flow of the present application is as follows: manually placing the object to be pasted on the receiving block, and moving the receiving block to the pasting station of the base; the stripping mechanism strips the soft adhesive tape from the soft adhesive disc, and the tape is moved to the cutting die opening of the cutting mechanism under the action of the transfer mechanism, the cutting pressure rod of the cutting mechanism cuts the tape at the cutting die opening under the action of the first power device to obtain a soft adhesive unit of a certain shape, then the cutting pressure rod continues to press down to paste the soft adhesive unit attached to the end of the tape on the object to be pasted, completing a pasting, then the first power device drives the cutting pressure rod to reset, and the transfer mechanism moves the cut part of the tape away, so that the new tape that has not been cut enters the cutting die opening, preparing for the next cutting and pasting, and so on. It should be noted that the edge part of the tape needs to be reserved during cutting, so that the tape remains continuous after cutting to avoid breaking the tape and to enable automatic feeding of the soft adhesive tape. In order to make the specific position of the object to be pasted correspond to the first end of the cutting channel, the receiving block should be provided with corresponding limiting structure to fix the placement position of the object, and when processing the same part of the same type of object, the receiving block does not need to be replaced, and when processing different types of objects, the original receiving block needs to be removed and replaced with another receiving block with corresponding limiting structure. In addition, when the area specification of the soft adhesive to be pasted needs to be changed, the specification of the positioning module and the cutting pressure rod is changed to change the area specification of the cutting die opening. The advantage of the present application is that the feeding, cutting and pasting of the soft adhesive can be automated, and compared with the scheme of using a mechanical arm to suck the soft adhesive and then pasting it, and the scheme of using a roller knife to paste, the present application does not have a long waiting period between two adjacent pasting operations, and the processing can be completed by repeatedly cutting and pasting, so that the processing interval between adjacent objects is more uniform, which is conducive to flow production. In addition, since the present application pastes through the cutting channel, as long as the placement position of the object is fixed, the position where the cutting channel and the object meet will also be fixed, and the pasting point of the soft adhesive can be ensured with high precision. On the other hand, the present application only needs to cut the large soft adhesive tape into a strip structure of corresponding width during processing, without directly cutting the tape into corresponding soft adhesive units, so the pretreatment time of the tape is greatly reduced, and the generation of edge scrap during cutting is also reduced, thereby reducing the cost. Another advantage of the present application is that when the adhesive position of the object or the size of the adhesive area is changed, only the corresponding elements need to be disassembled and replaced, so that the present device has strong versatility and can adapt to the production and processing of various products.

[0008] As a preferred embodiment of the present application, the second end of the cutting channel is communicated with a mounting groove, the mounting groove has a larger caliber than the cutting channel; the cutting pressure rod is connected with a pressure terminal at an end away from the receiving block, the pressure terminal has a larger caliber than the cutting pressure rod; the mounting groove and the cutting pressure rod are respectively formed with opposite first and second limiting surfaces; the cutting pressure rod is sleeved with a reset spring, and the two ends of the reset spring are respectively abutted with the first and second limiting surfaces. When the first power device is reset after one-time coating is completed, the pressure terminal is subjected to upward elastic force and abuts with the first power device, so as to avoid the gap between the connection structure of the pressure terminal and the first power device in the reset process, and to affect the running stability of the device, and at the same time, the reset spring can also play a buffering and damping role in the cutting process.

[0009] As a preferred embodiment of the present application, the first power device comprises a pressure rod connecting piece and a first power piece for controlling the axial movement of the pressure rod connecting piece along the cutting pressure rod; the pressure rod connecting piece has a containing cavity capable of accommodating the pressure terminal and a limiting part for preventing the pressure terminal from being taken out of the containing cavity, and the limiting part is provided with a connecting port through which the cutting pressure rod and the reset spring pass. In the process of depressing the first power piece, the inner wall of the containing cavity abuts with the upper surface of the pressure terminal, so as to move the pressure terminal downward, and then cut the soft rubber belt by the cutting pressure rod, and the reset spring provides upward elastic force to the pressure terminal in the reset process, so as to make the pressure terminal maintain abutment with the inner wall of the containing cavity, and avoid the gap.

[0010] As a preferred embodiment of the present application, the pressure rod connecting piece is further provided with a mounting through port for guiding the cutting pressure rod and the pressure terminal to be respectively introduced into the connecting port and the containing cavity in the radial direction. The cutting pressure rod and the pressure terminal can be moved in the radial direction through the mounting through port, so as to be moved to the corresponding positions of the containing cavity and the connecting port respectively, and the assembly of the pressure rod connecting piece, the cutting pressure rod and the pressure terminal is completed.

[0011] As a preferred embodiment of the present application, the transfer mechanism comprises a unwinding guide assembly arranged upstream of the cutting mechanism and a pulling guide assembly arranged downstream of the cutting mechanism; the pulling guide assembly comprises a pulling roller and a second power device for controlling the rotation of the pulling roller.

[0013] As a preferred embodiment of the present application, the width of the soft rubber channel is greater than the width of the cutting die port. Through the structure design, the edge part of the soft rubber belt can be reserved when the soft rubber belt is cut by the cutting pressure rod, so as to keep the soft rubber belt continuous and facilitate the feeding of the soft rubber belt.

[0014] As a preferred embodiment of the present application, the positioning and cutting assembly further comprises a module fixing member, and the positioning module is fitted and installed on the module fixing member.

[0015] As a preferred embodiment of the present application, the positioning module comprises an upper module and a lower module assembled with each other, and the soft rubber channel is formed at the joint of the upper module and the lower module. By means of the combination of the upper and lower modules, the difficulty of forming and processing of the positioning module can be reduced, the structural precision of the positioning module can be improved, and the positioning module can be easily and quickly disassembled for troubleshooting when abnormal conditions such as material jam occur in the positioning module.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Example

[0032] like Figure 1 As shown, this embodiment provides a soft adhesive material positioning and bonding device. The device includes a peeling mechanism, a cutting mechanism, a carrier mechanism, and a transfer mechanism fixedly mounted on a frame. The peeling mechanism is used to place a soft adhesive tray and peel off a soft adhesive strip from it. The cutting mechanism is used to cut soft adhesive units of a specific shape from the soft adhesive strip and apply the soft adhesive units to the object to be bonded. The carrier mechanism is used to place and fix the object to be bonded. The transfer mechanism is used to transfer the soft adhesive strip from the peeling mechanism to the cutting mechanism and then from the cutting mechanism to transport the cut strip out.

[0033] Specifically: the stripping mechanism 1 includes a tray for holding soft rubber tape; the transfer mechanism includes an unwinding guide assembly 2 disposed between the stripping mechanism and the cutting mechanism, a pulling guide assembly 8 disposed downstream of the cutting mechanism, and a second power unit 9. The pulling guide assembly includes a pair of pulling rollers, such as... Figure 5 As shown, one of the pulling rollers has a ratchet 81 at its end. The ratchet has a gear-like structure. The second power unit includes a power rack 91 and a second power component 92 connected to the power rack. The power rack and the ratchet form a mating structure. When the second power component moves the power rack upward, it can drive the ratchet to move upward. Figure 5 From a viewing angle, the ratchet rotates counterclockwise, which in turn drives the pulling roller to rotate counterclockwise. When the pulling roller rotates counterclockwise, the soft rubber strip between the two rollers is pulled outwards. The length of the soft rubber strip pulled out can be controlled by controlling the movement distance of the drive rack, thus achieving quantitative material pulling. The ratchet and drive rack have a unidirectional transmission structure, meaning that when the drive rack moves downwards, it does not drive the pulling roller to rotate in one direction. Figure 5 Rotate clockwise from the viewing angle to prevent the soft rubber waste from being rolled back.Figure 6 One of the embodiments of the one-way transmission structure is given, in Figure 6 which the ratchet wheel 81 includes the movable mounted ratchet and the limiting block arranged near the ratchet, the ratchet can rotate around its mounting shaft, when the power rack 91 moves upward, the ratchet wheel is connected with the power rack under the action of the limiting block, the power rack drives the ratchet wheel to rotate, when the power rack moves downward, the ratchet will shrink and not abut with the power rack, thus the ratchet wheel will not rotate. The above is only one of the embodiments for realizing the one-way transmission, under the premise of ensuring the one-way transmission effect, other equivalent alternative ways can also be adopted.

[0034] The cutting mechanism includes the module fixing piece 5 fixedly formed between the rack, the positioning module 6 cooperatively installed on the module fixing piece and the first power device 7 arranged above the positioning module, the cutting assembly is used for cutting the introduced soft rubber belt and pressing and pasting on the underlying object to be pasted; the carrier mechanism includes a base 3 and a receiving block 4 arranged on the base, the base is provided with a groove-shaped structure matched with the receiving block, so that the receiving block can be stably placed on the base, the receiving block is provided with a limiting structure corresponding to the object to be pasted, so that the object to be pasted cannot slide on the receiving block, and the outer side surface of the receiving block is provided with a pull rod, so as to facilitate taking out the receiving block.

As Figure 6 shown, the positioning module 6 is internally provided with a cutting channel 61, a soft rubber channel 62 and a mounting groove 63, the cutting channel and the soft rubber channel form a cutting die mouth 611 at the joint, the reset spring is arranged between the first limiting surface of the groove bottom of the mounting groove and the second limiting surface of the lower surface of the pressure contact end head, and abuts with the first limiting surface and the second limiting surface; the lower end of the cutting pressure rod extends into the cutting channel, and in the non-pressing state, the lower end of the cutting pressure rod should not exceed the position of the cutting die mouth, so as to ensure the smooth passing of the soft rubber belt. As Figure 4 shown, the positioning module 6 is composed of an upper module 6a and a lower module 6b, the joint part of the upper module and the lower module forms the soft rubber channel and the cutting die mouth.

[0036] The working principle of the soft adhesive material positioning and pasting device is as follows: firstly, the soft adhesive disc is installed on the stripping mechanism 1, so that the material belt is stripped from the soft adhesive disc, and the stripping mechanism is sequentially connected with the unwinding guide assembly 2, the positioning module 6 and the material pulling guide assembly 8, so that the device can automatically feed; the object to be pasted is placed on the receiving plate 4, and the receiving plate is placed on the base 5, then the second power member 9 is started to drive the material pulling roller of the material pulling guide assembly to rotate, the material pulling roller pulls the uncut part of the material belt to the cutting die mouth part of the positioning module, the first power member 73 is started to drive the cutting pressure rod to move downward, when the lower end of the cutting pressure rod moves to the cutting die mouth, the material belt is cut, a soft adhesive unit of a certain shape is cut from the material belt, then the cutting pressure rod continues to press down with the soft adhesive unit, finally the soft adhesive unit is pressed and pasted on the object to be pasted from the lower end of the cutting channel, after the pasting is completed, the first power member moves upward to drive the cutting pressure rod to reset, that is, one pasting is completed, then the material pulling roller pulls the cutting area of the material belt out of the cutting die mouth, so that the cutting die mouth is occupied by the new material belt, the receiving plate is taken off from the base, the pasted object is taken out, and a new object to be pasted is placed, so as to prepare for the next cutting and pressing.
