Description

Technical Field

[0001] The utility model relates to the technical field of refrigerator production, in particular to an automatic tape pasting device. Background Art

[0002] With the rapid development of the household appliance refrigerator manufacturing industry in the past few decades, manufacturing factories need to break through the problem of improving the aesthetic appreciation of product appearance, open up normal technologies in all aspects of products, innovate and optimize to improve the overall quality of products, and strengthen the explicit value of refrigerator appearance. During the refrigerator manufacturing process, the refrigerator door body is the first to appear in the customer's field of vision. The appearance quality after the overall assembly is a key factor in the refrigerator appearance evaluation, directly reflecting the user's appearance experience effect of high-end products, and is an important part of the improvement of high-end refrigerator brands, tastes, and qualities.

[0003] During the overall transportation of the refrigerator door body, due to its own weight inertia and the influence of bumpy road conditions and long-distance transportation, each hinge is deformed by different degrees of force, resulting in the sinking and skew of the door body. The overall appearance shows the problem of unequal door heights, seriously affecting the product aesthetics and brand value, and urgently needing technological breakthrough and improvement.

[0004] Before the refrigerator is assembled and off the production line, a door seal tape is pasted on the refrigerator door to prevent the door body from sinking or skewing during transportation. At present, the work of pasting the door seal tape on the refrigerator door is mainly completed manually, which not only has low work efficiency, but also easily causes the tape to be pasted crookedly or wrinkled, reducing the aesthetics. Summary of the Utility Model

[0005] The utility model provides an automatic tape pasting device, which solves the problems in the prior art that when manually pasting the door seal tape on the refrigerator door, there are problems such as low work efficiency, easy crooked and wrinkled tape pasting, and reduced aesthetics.

[0006] The technical solution of the utility model is realized as follows:

[0007] The utility model provides an automatic tape pasting device, including a conveying line body erected along the horizontal direction, and the conveying line body is used for conveying products to be pasted with tape; a machine frame is arranged on one side of the conveying line body, and a tape unwinding mechanism, a tape clamping and pulling mechanism, a tape shearing mechanism and a tape pasting mechanism are installed on the machine frame. The tape unwinding mechanism is used for releasing the tape, the tape clamping and pulling mechanism is used for clamping the end of the tape and pulling it to one side of the tape pasting mechanism, the tape shearing mechanism is used for cutting out a suitable length of tape, and the tape pasting mechanism is used for sucking the back of the tape and pasting the cut tape at a specified position on the product.

[0008] The utility model utilizes a conveyor line body to continuously convey a refrigerator to which a tape is to be pasted. A tape clamping and pulling mechanism clamps a tape from a tape unwinding mechanism and stretches it to one side of a tape pasting mechanism. The tape pasting mechanism sucks the back surface of the tape, then uses a tape shearing mechanism to cut the tape, and finally pastes the cut tape to a designated position on the refrigerator door through the tape pasting mechanism, realizing the full-automatic pasting of the refrigerator door seal tape, improving work efficiency, and solving problems such as skew and wrinkling existing in manual tape pasting.

[0009] Specifically, the tape unwinding mechanism includes a bottom plate. One side of the top surface of the bottom plate is provided with an ear plate. The inner side surface of the ear plate is provided with a horizontal winding drum, and a tape roll is sleeved on the winding drum. One side of the winding drum is provided with a first telescopic assembly. The telescopic end of the first telescopic assembly is provided with a flexible damping block. The side surface of the damping block facing the tape roll fits with the outer arc surface of the tape roll. The first telescopic assembly is used to push the damping block to fit with the outer arc surface of the tape roll. By arranging the first telescopic assembly on one side of the tape roll to push the damping block to fit with the tape roll, a certain damping effect can be applied to the rotation of the tape roll on the winding drum during the tape unwinding process, avoiding the tape from becoming slack due to too fast tape unwinding, and ensuring that the tape is always in a taut state during the unwinding process.

[0010] Further, a limiting assembly is provided at one end of the winding drum away from the ear plate. The limiting assembly is used to axially limit the winding drum in cooperation with the ear plate. The limiting assembly includes an insertion block. A vertical insertion slot is provided at one end of the winding drum away from the ear plate. The insertion block is inserted into the insertion slot, and the top of the insertion block extends out of the top opening of the insertion slot. By arranging the limiting assembly, the tape roll can be prevented from axially shifting during the unwinding process, thereby improving the accuracy of subsequent tape pasting.

[0011] Preferably, the bottom plate is slidably installed on the frame through a first linear module. The first linear module is used to drive the bottom plate to move along the axial direction of the winding drum. A plurality of tape rolls are axially sleeved on the winding drum. A bracket is installed on the frame, and a sensor assembly is installed inside the bracket for detecting whether the currently used tape roll on the winding drum has unwound all the tape. When the sensor assembly monitors that the currently used tape roll on the winding drum has been unwound, the first linear module can be controlled in a linked manner to drive the bottom plate to axially displace a certain distance along the winding drum, and switch to the next new tape roll, thereby realizing the automatic replacement of the tape roll.

[0012] Further, a horizontal second linear module is installed on the frame. The first linear module is slidably installed on the second linear module, and the first linear module and the second linear module are perpendicular to each other. By arranging the second linear module, it is convenient to drive the tape unwinding mechanism to displace outward to both sides to avoid the tape pasting mechanism when the tape pasting position is relatively low.

[0013] Specifically, the tape shearing mechanism is located above the tape unwinding mechanism, and a paste board is provided between the tape shearing mechanism and the tape unwinding mechanism. The paste board is installed on the bottom plate through a bracket, and the paste board is used for pasting and fixing the end of the tape; a plurality of through holes are formed in the pasting surface of the paste board; a second telescopic assembly and a third telescopic assembly are respectively arranged at two ends of the through hole. A top block is arranged at the telescopic end of the second telescopic assembly, and the second telescopic assembly is used for driving the top block to paste the tape on the paste board; a top rod is arranged at the telescopic end of the third telescopic assembly, and the third telescopic assembly is used for driving the top rod to pass through the through hole to push open the tape pasted on the paste board; by arranging the paste board, on the one hand, when manually loading the tape roll, the end of the tape can be pasted on the paste board, which is convenient for subsequent automatic tape replacement; on the other hand, when the tape clamping and pulling mechanism clamps the tape and stretches it to the side where the tape is pasted, the second telescopic assembly can be used to drive the top block to paste the tape on the paste board, so as to avoid the tape being pasted to other positions after being cut, resulting in the tape clamping and pulling mechanism being unable to clamp the end of the tape next time. When the tape clamping and pulling mechanism clamps the end of the tape next time, the third telescopic assembly can be used to drive the top rod to pass through the through hole of the paste board to push open the tape pasted on the paste board, which is convenient for the tape clamping and pulling mechanism to pull the tape for unwinding.

[0014] Specifically, the tape clamping and pulling mechanism includes a third linear module vertically installed on the frame. A pneumatic finger is slidably installed on the third linear module. The pneumatic finger is located directly above the tape unwinding mechanism. The third linear module is used for driving the pneumatic finger to move downward to the end of the tape to clamp the tape, and then driving the pneumatic finger to move upward to one side of the tape pasting mechanism. After the tape pasting mechanism sucks the tape, the pneumatic finger can release the end of the tape.

[0015] Specifically, the tape pasting mechanism includes a fourth linear module vertically installed on the frame. A horizontal fifth linear module is slidably installed on the fourth linear module. A horizontal sixth linear module is slidably installed on the fifth linear module. A vertical plate is slidably installed on the sixth linear module. A vacuum chuck for adsorbing the tape is installed on the side surface of the vertical plate; through the mutual cooperation of the fourth linear module, the fifth linear module and the sixth linear module, the vacuum chuck can be moved to the back of the tape to suck the tape. After the tape shearing mechanism cuts the tape, the vacuum chuck is then moved to the designated part of the refrigerator door to paste the tape.

[0016] Preferably, first positioning mechanisms are provided on both sides of the conveying line body, and a second positioning mechanism is provided at the bottom of the conveying line body. The first positioning mechanism includes a fourth telescopic assembly horizontally installed on the frame, and a clamping plate is provided at the telescopic end of the fourth telescopic assembly. The fourth telescopic assembly is used to drive the clamping plate to clamp and fix the product. The second positioning mechanism includes a fifth telescopic assembly vertically arranged, and a baffle is installed at the telescopic end of the fifth telescopic assembly. The fifth telescopic assembly is used to drive the baffle to pass through the gap between adjacent rollers on the conveying line body to block the product. By providing the first positioning mechanism on both sides of the conveying line body and the second positioning mechanism at the bottom of the conveying line body, the product can be fixed when the conveying line body transports the refrigerator to one side of the frame, preventing the refrigerator from shifting during the process of pasting the tape, resulting in an error in the tape pasting position.

[0017] Preferably, a code scanning device is provided on one side of the conveying line body for scanning the identification code on the product to obtain the product parameters, and the control cabinet can control the tape pasting mechanism to paste the tape at the specified position on the product according to the product parameters.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Referring to Figures 1 to 6 , an automatic tape pasting device is provided in an embodiment of the present utility model, including a conveyor line body 1 erected in the horizontal direction, and the conveyor line body 1 is used for conveying products to be pasted with tapes; a frame 2 is arranged on one side of the conveyor line body 1, and a tape unwinding mechanism 3, a tape clamping and pulling mechanism 4, a tape shearing mechanism 5 and a tape pasting mechanism 6 are installed on the frame 2. The tape unwinding mechanism 3 is used for releasing tapes, the tape clamping and pulling mechanism 4 is used for clamping the end of the tape and pulling it to one side of the tape pasting mechanism 6, the tape shearing mechanism 5 is used for cutting out tapes of appropriate lengths, and the tape pasting mechanism 6 is used for sucking the back of the tape and pasting the cut tape at a specified position of the product.

[0028] The present utility model utilizes the conveyor line body 1 to continuously convey refrigerators to be pasted with tapes, uses the tape clamping and pulling mechanism 4 to clamp the tape from the tape unwinding mechanism 3 and stretch it to one side of the tape pasting mechanism 6, sucks the back of the tape through the tape pasting mechanism 6, then uses the tape shearing mechanism 5 to cut the tape, and finally pastes the cut tape at the specified position of the refrigerator door through the tape pasting mechanism 6, realizing the full-automatic pasting of the refrigerator door sealing tape, improving the work efficiency, and solving the problems such as skew and wrinkling existing in manual tape pasting.

[0029] Specifically, as Figures 2 to 4As shown in the figure, the tape unwinding mechanism 3 includes a bottom plate 7. On one side of the top surface of the bottom plate 7, there is an ear plate 8. On the inner side of the ear plate 8, there is a horizontal winding drum 9. A tape roll 10 is sleeved on the winding drum 9. On one side of the winding drum 9, there is a first telescopic assembly 11. The telescopic end of the first telescopic assembly 11 is provided with a flexible damping block 12. The side of the damping block 12 facing the tape roll 10 is attached to the outer arc surface of the tape roll 10. The first telescopic assembly 11 is used to push the damping block 12 to be attached to the outer arc surface of the tape roll 10. By setting the first telescopic assembly 11 on one side of the tape roll 10 to push the damping block 12 to be attached to the tape roll 10, a certain damping effect can be applied to the rotation of the tape roll 10 on the winding drum 9 during the tape unwinding process, avoiding the tape from becoming loose due to too fast tape unwinding, and ensuring that the tape is always in a taut state during the unwinding process.

[0030] Further, as Figure 3 shown, a limiting assembly is provided at one end of the winding drum 9 away from the ear plate 8. The limiting assembly is used to cooperate with the ear plate 8 to axially limit the winding drum 9. The limiting assembly includes an insertion block 13. A vertical slot 14 is provided at one end of the winding drum 9 away from the ear plate 8. The insertion block 13 is inserted into the slot 14, and the top of the insertion block 13 extends out of the top opening of the slot 14. By setting the limiting assembly, the tape roll 10 can be prevented from axially shifting during the unwinding process, thereby improving the accuracy of subsequent tape pasting.

[0031] Preferably, as Figure 2 、 4 shown, the bottom plate 7 is slidably mounted on the frame 2 through a first linear module 15. The first linear module 15 is used to drive the bottom plate 7 to move along the axial direction of the winding drum 9. A number of tape rolls 10 are axially sleeved on the winding drum 9 (in this embodiment, a total of 4 tape rolls 10 can be installed on the winding drum 9, and the specific number can be flexibly configured according to the length of the winding drum 9). A bracket is installed on the frame 2, and a sensor assembly 16 is installed inside the bracket, which is used to detect whether the currently used tape roll 10 on the winding drum 9 has unwound all the tape. When the sensor assembly 16 monitors that the currently used tape roll 10 on the winding drum 9 has been unwound, the first linear module 15 can be controlled to drive the bottom plate 7 to axially displace a certain distance, and switch to the next new tape roll 10, so as to realize the automatic replacement of the tape roll 10.

[0032] Further, as Figure 2 shown, a horizontal second linear module 17 is installed on the frame 2. The first linear module 15 is slidably mounted on the second linear module 17, and the first linear module 15 and the second linear module 17 are perpendicular to each other. By setting the second linear module 17, it is convenient to drive the tape unwinding mechanism 3 to displace outward on both sides to avoid the tape pasting mechanism 6 when the tape pasting position is relatively low.

[0033] Specifically, as Figure 4 shown, the tape shearing mechanism 5 is located above the tape unwinding mechanism 3, and a pasting plate 18 is provided between the tape shearing mechanism 5 and the tape unwinding mechanism 3. The pasting plate 18 is mounted on the bottom plate 7 through a bracket, and the pasting plate 18 is used for pasting and fixing the end of the tape; a plurality of through holes 19 are formed in the pasting surface of the pasting plate 18; a second telescopic assembly 20 and a third telescopic assembly 21 are respectively provided at both ends of the through hole 19. A top block 22 is provided at the telescopic end of the second telescopic assembly 20, and the second telescopic assembly 20 is used to drive the top block 22 to paste the tape on the pasting plate 18; a top rod 23 is provided at the telescopic end of the third telescopic assembly 21, and the third telescopic assembly 21 is used to drive the top rod 23 to pass through the through hole 19 to push open the tape pasted on the pasting plate 18; by providing the pasting plate 18, on the one hand, when manually loading the tape roll 10, the end of the tape can be pasted on the pasting plate 18, which is convenient for subsequent automatic tape replacement; on the other hand, when the tape clamping and pulling mechanism 4 clamps the tape and stretches it to the tape pasting side, the second telescopic assembly 20 can be used to drive the top block 22 to paste the tape on the pasting plate 18, so as to prevent the tape from being pasted to other positions after being cut, resulting in the tape clamping and pulling mechanism 4 being unable to clamp the end of the tape next time. When the tape clamping and pulling mechanism 4 clamps the end of the tape next time, the third telescopic assembly 21 can be used to drive the top rod 23 to pass through the through hole 19 of the pasting plate 18 to push open the tape pasted on the pasting plate 18, which is convenient for the tape clamping and pulling mechanism 4 to pull the tape for unwinding.

[0034] Specifically, in this embodiment, the tape shearing mechanism 5 can adopt a pneumatic scissors.

[0035] Specifically, as Figure 5 shown, the tape clamping and pulling mechanism 4 includes a third linear module 24 vertically installed on the frame 2. A pneumatic finger 25 is slidably installed on the third linear module 24. The pneumatic finger 25 is located directly above the tape unwinding mechanism 3. The third linear module 24 is used to drive the pneumatic finger 25 to move downward to the end of the tape to clamp the tape, and then drive the pneumatic finger 25 to move upward to one side of the tape pasting mechanism 6. After the tape pasting mechanism 6 sucks the tape, the pneumatic finger 25 can release the end of the tape.

[0036] Specifically, as Figure 5As shown in the figure, the tape pasting mechanism 6 includes a fourth linear module 26 vertically installed on the frame 2. A horizontal fifth linear module 27 is slidably installed on the fourth linear module 26. A horizontal sixth linear module 28 is slidably installed on the fifth linear module 27. A vertical plate 29 is slidably installed on the sixth linear module 28. A vacuum chuck 30 for adsorbing the tape is installed on the side of the vertical plate 29. Through the mutual cooperation of the fourth linear module 26, the fifth linear module 27 and the sixth linear module 28, the vacuum chuck 30 can be moved to the back of the tape to suck the tape. After the tape cutting mechanism 5 cuts the tape, the vacuum chuck 30 is then moved to the designated position on the refrigerator door to paste the tape.

[0037] Preferably, as Figure 6 shown, first positioning mechanisms are provided on both sides of the conveyor line body 1, and a second positioning mechanism is provided at the bottom of the conveyor line body 1. The first positioning mechanism includes a fourth telescopic assembly 31 horizontally installed on the frame 2. A clamping plate 32 is provided at the telescopic end of the fourth telescopic assembly 31. The fourth telescopic assembly 31 is used to drive the clamping plate 32 to clamp and fix the product. The second positioning mechanism includes a fifth telescopic assembly 33 vertically arranged. A baffle 34 is installed at the telescopic end of the fifth telescopic assembly 33. The fifth telescopic assembly 33 is used to drive the baffle 34 to pass through the gap between adjacent rollers on the conveyor line body 1 to block the product. By providing the first positioning mechanism on both sides of the conveyor line body 1 and the second positioning mechanism at the bottom of the conveyor line body 1, the product can be fixed when the conveyor line body 1 transports the refrigerator to one side of the frame 2, preventing the refrigerator from shifting during the tape pasting process, resulting in an error in the tape pasting position.

[0038] Preferably, as Figure 6 shown, a code scanning device 35 is provided on one side of the conveyor line body 1 for scanning the identification code on the product to obtain the parameters of the product. The control cabinet can control the tape pasting mechanism 6 to paste the tape at the designated position on the product according to the parameters of the product.

[0039] In this embodiment, the first linear module 15, the second linear module 17, the third linear module 24, the fourth linear module 26, the fifth linear module 27, the sixth linear module 28, the first telescopic assembly 11, the second telescopic assembly 20, the third telescopic assembly 21, the fourth telescopic assembly 31, and the fifth telescopic assembly 33 can all be driven by air cylinders (or driven by reduction motors. In the specific implementation process, they can be flexibly selected according to the actual situation), and corresponding guide shafts and guide sleeves are configured to ensure the displacement accuracy.

[0040] The automatic tape sticking equipment in this embodiment is a double-station configuration, that is, two sets of tape unwinding mechanisms 3, two sets of tape cutting mechanisms 5, two sets of tape clamping and pulling mechanisms 4 and two sets of tape sticking mechanisms 6 are designed, which can stick two tapes to two designated positions of the refrigerator door at the same time, thereby improving work efficiency.

[0041] The automatic adhesive tape applying equipment of this embodiment is equipped with a control cabinet for realizing full automatic control of the equipment.

[0042] The working process of the automatic tape sticking device of this embodiment is as follows:

[0043] First, remove the insert block 13 in the slot 14 at the end of the reel 9, and put the four tape rolls 10 on the reel 9 in turn. A total of eight tape rolls 10 are installed in the double station. Then, insert the insert block 13 into the slot 14 of the reel 9 to limit the axial position of the tape roll 10. Then, manually pull out the end of each roll of tape and paste it to the corresponding position on the pasting plate 18 (the pasting plate 18 is provided with four through holes 19, each through hole 19 corresponds to the pasting position of a roll of tape. When pasting the tape, it is necessary to ensure that the end of the tape exceeds the top surface of the pasting plate 18, and reserve the length for the pneumatic clamping fingers 25 to clamp). Then, control the first telescopic component 11 to extend and drive the damping block 12 to press against the outer wall of the innermost tape roll 10 (at this time, the innermost tape roll 10 on the reel 9 is facing the pneumatic scissors above, which is the tape roll 10 currently in use).

[0044] Then, the conveyor line 1 is controlled to convey the refrigerator to be pasted with the tape to a designated position on one side of the rack 2 and then stop, and the QR code or barcode on the refrigerator is scanned by the code scanning device 35 on one side of the conveyor line 1 to obtain parameter information such as the model of the refrigerator; then the fourth telescopic components 31 on both sides of the conveyor line 1 are controlled to extend at the same time to drive the corresponding clamping plates 32 to clamp the two sides of the refrigerator, and the fifth telescopic component 33 at the bottom of the conveyor line 1 is controlled to extend and drive the corresponding baffle 34 to pass through the gap between adjacent rollers on the conveyor line 1 to block the front end of the refrigerator, so as to fix the product;

[0045] Then control the third linear module 24 to drive the pneumatic finger 25 to move downward above the pasting plate 18, and clamp the part of the tape exposed on the top surface of the pasting plate 18. Then control the third telescopic assembly 21 to extend and drive the ejector rod 23 to pass through the corresponding through hole 19 to push open the tape pasted on the pasting plate 18, and then control the third telescopic assembly 21 to drive the ejector rod 23 to withdraw from the through hole 19; the third linear module 24 drives the pneumatic finger 25 holding the tape to move upward to one side of the vacuum suction cup 30, so that the back surface (i.e., the side without the adhesive layer) of the tape is aligned with the adsorption surface of the vacuum suction cup 30. After the tape is unwound to an appropriate length, control the vacuum suction cup 30 to suck the back surface of the tape, and then control the second telescopic assembly 20 to extend and drive the top block 22 to paste the bottom end of the tape on the pasting plate 18. Then control the second telescopic assembly 20 to drive the top block 22 to retract, and then control the pneumatic scissors to cut the tape. The pneumatic scissors are located above the top surface of the pasting plate 18. After the tape is cut, a length for the pneumatic finger 25 to clamp the tape next time is reserved.

[0046] Then control the fourth linear module 26, the fifth linear module 27 and the sixth linear module 28 to cooperate with each other, and move the vacuum suction cup 30 to the corresponding tape pasting part of the refrigerator according to the parameter information such as the product model of the refrigerator for pasting, and then move the vacuum suction cup 30 back to the initial position after pasting.

[0047] During the process of unwinding the tape, the photoelectric sensor is used to monitor in real time whether the currently used tape roll 10 has been unwound completely. When the tape roll 10 has been unwound completely, the photoelectric sensor cannot detect the tape, and the control cabinet will control the first linear module 15 to drive the bottom plate 7 to displace a certain distance (i.e., the thickness of the tape roll 10) along the axial direction of the reel 9 according to this signal, and switch to the next new tape roll 10.

[0048] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
