Description

Technical Field

[0001] This invention belongs to the field of magnetic strip insertion technology for door seals, specifically, it relates to a magnetic strip sorting and insertion assembly line for refrigerator door seal production. Background Technology

[0002] As refrigerators are used more and more widely in people's lives, the demand for refrigerator door sealing components, such as door seals, is also increasing. Refrigerator door seals are mainly composed of a rubber sleeve and a magnetic strip. Inserting the magnetic strip into the rubber sleeve forms a preliminary semi-finished door seal. Then, the door seal is welded into the shape of the refrigerator door and installed on the refrigerator door for use.

[0003] The current production of door seals typically involves magnetic strip manufacturers producing, winding, and storing the magnetic strips, then transporting them to a sleeve manufacturer. The rolled magnetic strips are then cut to lengths matching the sleeves. Since sleeves come in different lengths, manual sorting is required to insert the matching magnetic strips. After manual insertion, welding is performed. This process, involving the winding and transport of the magnetic strips to the sleeve manufacturer, introduces unnecessary costs into door seal production. Therefore, we propose integrating the magnetic strip insertion process with the magnetic strip production equipment. This means connecting the magnetic strip insertion equipment to the magnetic strip manufacturer's production line. This eliminates the need for winding and transporting the magnetic strips after extrusion, allowing for direct insertion without manual intervention. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a magnetic strip sorting and insertion assembly line for refrigerator door seal production that can overcome or at least partially solve the above problems.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: a magnetic strip for refrigerator door seal production is sorted and inserted into an assembly line, including a mounting platform, and further including: a placement plate, located on the mounting platform, the placement plate having a drop groove, and a drop groove forming between the placement plate and the mounting platform; a stacking frame, placed on the placement plate, the stacking frame having multiple stacking slots, the stacking slots corresponding to the drop grooves; and a mounting plate, located on the mounting platform, the mounting plate having a drive wheel and a pressing wheel rotatably disposed thereon, the drive wheel being used to drive the magnetic strip. The magnetic strip moves along a track, with the clamping wheel pressing the magnetic strip against the drive wheel; a mounting frame, located on one side of the mounting platform, has multiple cyclically moving slides on it, each slide having a guide rod mounted on its slide base, and a magnetic block at the front end of the guide rod, allowing the guide rod to extend into the drop groove below the drop groove and pass through the rubber sleeve. The slide then slides towards the mounting platform, attracting the magnetic block to one end of the magnetic strip, guiding the magnetic strip into the rubber sleeve via the guide rod; pneumatic shears are used to cut the magnetic strip.

[0006] Furthermore, a second cylinder is installed on the mounting platform, and a connecting plate is fixedly connected to the telescopic end of the second cylinder. A plug-in block is fixedly connected to the outer side of the lower end of the stacking frame, and the plug-in block corresponds to the slot on the connecting plate. The second cylinder is used to push the stacking frame to move on the placement plate, so that the multiple stacking slots correspond one by one to the drop slots.

[0007] Preferably, the mounting frame is symmetrically rotatably connected with rotating shafts, and a connecting belt is connected between two rotating shafts. Multiple sliding tables are mounted on the outer surface of the connecting belt. A second motor is mounted on the mounting frame, and the output end of the second motor is connected to the rotating shafts.

[0008] Furthermore, the guide rod has an air groove, and a connecting air nozzle connected to the air groove is installed on the side of the guide rod near the slide. The guide rod has multiple air outlets connected to the air groove, which are used to cause the rubber sleeve to expand when the guide rod is inserted into the rubber sleeve.

[0009] Furthermore, a negative pressure suction nozzle is provided on the mounting platform for positioning the rubber sleeve.

[0010] Furthermore, a lifting positioning plate is slidably arranged on the mounting platform, and a first cylinder is fixedly connected to the bottom of the mounting platform, with the telescopic end of the first cylinder fixedly connected to the lifting positioning plate.

[0011] Furthermore, the mounting plate is rotatably connected with a first guide wheel, a second guide wheel, and a third guide wheel. The second guide wheel is located between the first guide wheel and the third guide wheel, and is located below the first guide wheel and the third guide wheel, forming the magnetic strip buffer zone.

[0012] Furthermore, it also includes a pushing mechanism for pushing the rubber sleeve fitted with the magnetic strip away from the mounting platform.

[0013] Preferably, the pushing mechanism includes a fourth cylinder, which is mounted on the connecting belt between the two slides.

[0014] Furthermore, the mounting platform is fixedly connected to an inclined plate on one side of the lifting and positioning plate.

[0015] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention is equipped with multiple slides that follow the movement of the connecting belt. The guide rod on the slide first enters the rubber sleeve and drives the rubber sleeve to move to the corresponding position of the magnetic strip. The guide rod then pulls the magnetic strip into the rubber sleeve. Moreover, the present invention can be combined with the existing magnetic strip production line, so there is no need to wind the magnetic strip. The rubber sleeve process is performed directly after the magnetic strip is produced, which saves costs for enterprises. In addition, the present invention has a high degree of automation and can save labor costs.

[0016] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0030] Example:

[0031] Reference Figures 1-10A magnetic strip for refrigerator door seal production is sorted and inserted into an assembly line, including a mounting platform 1, and further including: a placement plate 11, located on the mounting platform 1, with a drop groove 111 on the placement plate 11, forming a drop groove 104 between the placement plate 11 and the mounting platform 1; a stacking frame 12, placed on the placement plate 11, with multiple stacking slots 121 in the stacking frame 12, the number of stacking slots 121 can be set according to actual needs, in this embodiment, the number of stacking slots 121 is set to 6, the stacking slots 121 correspond to the drop grooves 111; a mounting plate 15, located on the mounting platform 1, with a drive wheel 151 and a pressing wheel 152 respectively rotatably arranged on the mounting plate 15, the drive wheel 151 is used to drive the magnetic strip 10 to move, and the pressing wheel 152 is used to press the magnetic strip 10 onto the drive wheel 151; a mounting frame 2, located on one side of the mounting platform 1, with multiple circulating sliding tables 23 arranged on the mounting frame 2, in this embodiment, the sliding tables 23 The quantity is 7. The number of slides 23 can be set according to the circumference of the connecting belt 22 and the distance between the drive wheel 151 and the drop groove 111. A guide rod 232 is installed on the slide base 231 of the magnetic strip 10 slide 23. A magnetic block 235 is provided at the front end of the guide rod 232. The guide rod 232 is inserted into the drop groove 104 below the drop groove 111 and passes through the rubber sleeve. Then the slide 23 slides to one side of the mounting platform 1 and the magnetic block... 235 attracts one end of the magnetic strip 10, and guides the magnetic strip 10 into the rubber sleeve through the guide rod 232; pneumatic scissors 132 are used to cut the magnetic strip 10. The pneumatic scissors 132 are mounted on the mounting platform 1 through the connecting bracket 13. The connecting bracket 13 is equipped with a third cylinder 131. The pneumatic scissors 132 are mounted on the telescopic end of the third cylinder 131. The third cylinder 131 drives the pneumatic scissors 132 to move down and cut the magnetic strip 10.

[0032] This device is mainly installed behind the magnetic strip 10 production line. The last process of the existing magnetic strip 10 production line is the winding process, that is, the magnetized magnetic strip 10 is wound onto the take-up cylinder for easy transportation and storage.

[0033] The purpose of this device is to eliminate the existing winding process. By installing this device, the magnetic strip 10 does not need to be wound up. Instead, the process of inserting the rubber sleeve is performed directly after the magnetic strip 10 is produced.

[0034] The operation of this device mainly involves placing rubber sleeves of uniform length into a stacking frame 12. The stacking frame 12 is provided with multiple stacking slots 121, which can prevent the rubber sleeves from being messy and thus stack the rubber sleeves in sections. Since the two ends of the stacking frame 12 are open, a drop slot 111 corresponding to the stacking slot 121 is provided on the placement plate 11, so that the rubber sleeves in the stacking slot 121 can fall into the mounting platform 1, that is, the drop slot 104, through the drop slot 111.

[0035] The height of the drop trough 104 is only the height of one rubber sleeve. Therefore, when the stacking trough 121 corresponds to the drop trough 111, there will only be one rubber sleeve on the mounting platform 1, thus avoiding the simultaneous drop of multiple rubber sleeves.

[0036] Subsequently, the slides 23, which move in a series of cycles, move one by one to the side of the rubber sleeve at the drop trough 104. The slide block 231 on the slide 23 moves closer to the rubber sleeve, and one end of the guide rod 232 on the slide block 231 is inserted into the rubber sleeve, that is, into the groove of the magnetic strip 10. When the guide rod 232 is inserted into the rubber sleeve located below the drop trough 104, the slide 23 moves away from the placement plate 11. This movement will cause the rubber sleeve in the drop trough 104 to move away from the drop trough 104. When the rubber sleeve moves away from the drop trough 104, the rubber sleeve in the stacking groove 121 falls back into the drop trough 104 through the drop groove 111.

[0037] As the slide table 23 moves, the rubber sleeve moves away from the placement plate 11 and stops opposite the drive wheel 151. The drive wheel 151 is driven to rotate by the first motor 150 mounted on the mounting plate 15, which moves the magnetic strip 10 towards the guide rod 232. A magnetic block 235 is provided on one end of the guide rod 232. When the magnetic strip 10 moves, one end attracts the magnetic block 235. Then, the slide seat 231 on the slide table 23 moves away from the rubber sleeve, and simultaneously moves the guide rod 232, causing the guide rod 232 to move. 2. Drive the magnetic strip 10 into the rubber sleeve. When the slide 231 is about to move to the set position, the pneumatic scissors 132 cut the magnetic strip 10. After cutting, the guide rod 232 continues to slide a distance to completely insert the magnetic strip 10 into the rubber sleeve, thus completing the insertion of the magnetic strip 10. After the magnetic strip 10 enters the rubber sleeve, a stop is set on the mounting table 1. The stop is used to block the end of the rubber sleeve close to the slide 23, so that when the guide rod 232 comes out of the rubber sleeve after the magnetic strip 10 is inserted into the rubber sleeve, it will prevent the magnetic strip 10 from being pulled out.

[0038] When the magnetic strip 10 is cut, the drive wheel 151 stops rotating, causing the end of the magnetic strip 10 to stop moving and preventing the magnetic strip 10 from continuing to move;

[0039] After the rubber sleeve that has been inserted into the magnetic strip 10 is removed from the mounting table 1, another guide rod 232 inserted into the rubber sleeve below the drop groove 111 moves the rubber sleeve back to the relative position of the magnetic strip 10 when multiple slides 23 move together, waiting for the next magnetic strip 10 to be inserted, thus realizing the continuous magnetic strip 10 insertion process.

[0040] In one embodiment, a second cylinder 122 is installed on the mounting platform 1. A connecting plate 123 is fixedly connected to the telescopic end of the second cylinder 122. A plug-in block 124 is fixedly connected to the outer side of the lower end of the stacking frame 12. The plug-in block 124 corresponds to the slot on the connecting plate 123. The second cylinder 122 is used to push the stacking frame 12 to move on the placement plate 11, so that multiple stacking slots 121 correspond one by one to the drop slots 111.

[0041] In order to facilitate the movement of the stacking frame 12 by the second cylinder 122 after the rubber sleeve in a certain stacking slot 121 in the stacking frame 12 is emptied, the next stacking slot 121 is moved to the drop slot 111, so that the rubber sleeve in the stacking frame 12 can continuously fall through the drop slot 111 to the drop slot 104.

[0042] In addition, the time for the second cylinder 122 to push the stacking frame 12 can be set according to the speed and time of the rubber sleeve falling in a single stacking slot 121. That is, the extension time and number of times the extension end of the second cylinder 122 can be adjusted according to the actual situation.

[0043] It should be understood that the second cylinder 122 has a multi-stage telescopic design;

[0044] The stacking frame 12 can be manually moved onto the placement plate 11 or moved onto the placement plate 11 by a robotic arm. The insertion block 124 on one side of the placement plate 11 can connect the stacking frame 12 to the connecting plate 123 when the stacking frame 12 is placed on the placement plate 11. At the same time, since the rubber sleeves have different lengths, different models of stacking frames 12 can be placed according to the different types and lengths of rubber sleeves.

[0045] In one embodiment, a rotating shaft 21 is symmetrically rotatably connected to the mounting frame 2, a connecting belt 22 is connected between the two rotating shafts 21, a plurality of slides 23 are mounted on the outer surface of the connecting belt 22, a second motor 20 is mounted on the mounting frame 2, and the output end of the second motor 20 is connected to the rotating shaft 21.

[0046] The slide table 23 is mounted on the connecting belt 22, and then the second motor 20 drives the rotating shaft 21 to rotate, so that the connecting belt 22 drives the slide table 23 to rotate.

[0047] In order to improve the support effect of the slide table 23 and prevent the connecting belt 22 from deforming under stress, multiple connecting belts 22 are set on the rotating shaft 21 to distribute the weight of the slide table 23, thereby preventing the connecting belt 22 from deforming and the position of the slide table 23 from changing.

[0048] Meanwhile, in order to ensure the accurate movement of the slide table 23, a synchronous pulley or sprocket can be installed on the rotating shaft 21, and the connecting belt 22 can be set as a synchronous belt or chain. This can improve the accuracy of the movement distance of the slide table 23 when the connecting belt 22 rotates, and can also further prevent the connecting belt 22 from deforming under force.

[0049] Meanwhile, in order to further prevent deformation of the connecting belt 22, a support frame can be set inside the connecting belt 22 to support the inside of the connecting belt 22 and thus prevent deformation.

[0050] In one embodiment, an air groove 233 is provided in the guide rod 232, and a connecting air nozzle 236 connected to the air groove 233 is installed on the side of the guide rod 232 near the slide block 231. A plurality of air outlet holes 234 connected to the air groove 233 are provided on the guide rod 232 to cause the rubber sleeve to expand when the guide rod 232 is inserted into the rubber sleeve.

[0051] By opening an air vent 234 on the guide rod 232, when the guide rod 232 is inserted into the rubber sleeve, the air vent 234 releases air, filling the rubber sleeve with gas. The gas causes the rubber sleeve to expand, making the groove for inserting the magnetic strip 10 larger, which further facilitates the magnetic strip 10 to pass into the rubber sleeve.

[0052] Meanwhile, an air vent 234 is positioned near the front end of the guide rod 232, that is, the end away from the slide block 231. This makes the air vent 234 closer to the end of the rubber sleeve near the magnetic strip 10 after the guide rod 232 is inserted into the rubber sleeve. When the air vent 234 exhausts air, it can open the opening of the rubber sleeve by the gas, making it easier for the guide rod 232 to pull the magnetic strip 10 into the rubber sleeve, and thus making it easier for the magnetic strip 10 to pass through the rubber sleeve.

[0053] The gas in the vent 234 can be supplied to the air tank 233 by installing an air pump on the connecting belt 22 and connecting the connecting nozzle 236 to the air pump through an air pipe, without worrying about the air pipe getting tangled when the connecting belt 22 rotates.

[0054] Furthermore, by setting up a solenoid valve, it is possible to control the air pump to supply air to a certain connected air nozzle 236, thereby avoiding gas waste.

[0055] The mounting platform 1 is equipped with a negative pressure suction nozzle 14 for positioning the rubber sleeve;

[0056] By setting a negative pressure suction nozzle 14 on the mounting platform 1, when the rubber sleeve located in the drop groove 104 is carried away by the guide rod 232 to the placement plate 11 and reaches the position opposite to the magnetic strip 10, the negative pressure suction nozzle 14 can suck up the rubber sleeve on the guide rod 232. There are multiple negative pressure suction nozzles 14, which are arranged horizontally. This allows the rubber sleeve to be sucked and fixed when it moves to the negative pressure suction nozzle 14, while keeping the rubber sleeve horizontal and avoiding skewing.

[0057] In one embodiment, a lifting positioning plate 101 is slidably disposed on the mounting platform 1, and a first cylinder 102 is fixedly connected to the bottom of the mounting platform 1, with the telescopic end of the first cylinder 102 fixedly connected to the lifting positioning plate 101.

[0058] The lifting positioning plate 101 is located on the mounting platform 1 at the relative position of the magnetic strip 10. The lifting positioning plate 101 is mainly used to quickly position the rubber sleeve when the guide rod 232 moves to the relative position of the magnetic strip 10. At the same time, when the guide rod 232 brings the rubber sleeve to the relative position of the magnetic strip 10, the side of the lifting positioning plate 101 can further straighten the rubber sleeve to prevent the rubber sleeve from being crooked, thereby improving the efficiency and convenience of inserting the magnetic strip 10.

[0059] The lifting and positioning plate 101 is controlled to lift and lower by the first cylinder 102. After the magnetic strip 10 is inserted into the rubber sleeve, it is easy to lower and keep horizontal with the upper surface of the mounting platform 1, so that the rubber sleeve with the magnetic strip 10 inserted can be easily removed from the mounting platform 1.

[0060] The mounting plate 15 is rotatably connected to a first guide wheel 153, a second guide wheel 154, and a third guide wheel 155. The second guide wheel 154 is located between the first guide wheel 153 and the third guide wheel 155, and is located below the first guide wheel 153 and the third guide wheel 155, forming a buffer zone for the magnetic strip 10.

[0061] The arrangement of the first guide wheel 153, the second guide wheel 154, and the third guide wheel 155 can pull the magnetic strip 10. At the same time, by winding the magnetic strip 10 around the first guide wheel 153, the second guide wheel 154, and the third guide wheel 155, the magnetic strip 10 can be kept taut and prevented from loosening.

[0062] The buffer zone is formed so that when the pneumatic shears 132 cuts the magnetic strip 10 and the drive wheel 151 stops rotating briefly, the magnetic strip 10 production equipment can store material under the second guide wheel 154 to achieve the purpose of buffering.

[0063] It also includes a pushing mechanism for pushing the rubber sleeve with the magnetic strip 10 off the mounting table 1.

[0064] The pushing mechanism includes a fourth cylinder 24, which is mounted on the connecting belt 22 between the two slides 23. The fourth cylinder 24 can push the rubber sleeve with the magnetic strip 10 inserted into the rubber sleeve from the mounting platform 1 when the connecting belt 22 drives the slide 23 to move.

[0065] The mounting platform 1 is fixedly connected to an inclined plate 103 on one side of the lifting and positioning plate 101, and slides off onto the inclined plate 103 when pushed away.

[0066] A collection frame is placed below the inclined plate 103 to collect the rubber sleeve through which the magnetic strip 10 is inserted.

[0067] This invention features multiple sliding tables 23 that move with the connecting belt 22. Guide rods 232 on the sliding tables 23 first insert into the rubber sleeve and move the rubber sleeve to the corresponding position of the magnetic strip 10. The guide rods 232 then pull the magnetic strip 10 into the rubber sleeve. This device can be combined with existing magnetic strip 10 production lines, eliminating the need to wind up the magnetic strip 10. The insertion into the rubber sleeve is performed directly after the magnetic strip 10 is produced, saving costs for enterprises. Furthermore, this device has a high degree of automation, which can save on labor costs.

[0068] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
