Description

Riveting and gluing station for large and small coamings of refrigerator inner container

Technical Field

The invention relates to a device for preparing a port-shaped coaming, which is formed by mutually riveting a large coaming and a small coaming in an automatic production line of a refrigerator liner.

Background

The refrigerator liner coaming is used for isolating the refrigerator liner and the refrigerating device. The liner coaming of the refrigerator is usually made of patterned aluminum plates. Generally, the refrigerator liner coaming is formed by riveting a U-shaped coaming made of two patterned aluminum plates to form a port-shaped coaming, and then riveting a bottom plate. And after the two U-shaped coamings are riveted one by one and then are riveted with the Z-shaped bottom plate, the refrigerator liner coamings with the step shape are formed. In the prior art, riveting is realized by a shell riveting device disclosed in a patent document CN 105798180A between two U-shaped coamings with different sizes. However, this riveting apparatus has two problems: the first problem is that the riveting equipment is driven by a double-stroke oil cylinder, so that time consumption is long when two steps are impacted step by step in processing, and the steps cannot keep pace with the rhythm of the whole refrigerator liner coaming production line. The second problem is that the riveting backing plate is arranged outside the shell, the riveting impact plate is arranged inside the shell, and four corners of the two U-shaped coamings are fixed when the aluminum plate with the weaker texture is subjected to riveting processing. The best method for fixing four corners of the U-shaped coaming is to prop up the U-shaped coaming from inside by using the upright posts, so that when the upright posts of the U-shaped coaming prop up from inside to outside, the riveting backing plate on the outer side of the shell needs to move from outside to inside.

A refrigerator inner container size coaming riveting and gluing station is shown in fig. 1, and comprises a port-shaped coaming riveting device 2300, two robot manipulators and a corner line gluing part. Wherein the two robotic manipulators are a first robotic manipulator 2301 and a second robotic manipulator 2302, respectively. The I-shaped coaming riveting equipment 2300 is used for riveting two end lines of a U-shaped large coaming and a U-shaped small coaming to form an I-shaped coaming. The cross-shaped coaming riveting device 2300 is positioned between a blanking part 2101 of a U-shaped large coaming production line and a blanking part 2201 of a U-shaped small coaming production line. The blanking part 2101 of the U-shaped large coaming production line and the blanking part 2201 of the U-shaped small coaming production line are respectively positioned at two diagonal directions of the port-shaped coaming riveting equipment 2300. The first robotic manipulator 2301 and the second robotic manipulator 2302 are respectively located at both ends of the port-shaped coaming riveting device 2300. The first robot manipulator 2301 is close to a blanking part 2101 of the U-shaped large coaming production line and is used for transferring the U-shaped large coaming prepared by the U-shaped large coaming production line from the blanking part 2101 of the U-shaped large coaming production line to the port-shaped coaming riveting equipment 2300; the second robot manipulator 2302 is close to the blanking portion 2201 of the U-shaped small coaming production line, and is used for transferring the U-shaped small coaming prepared by the U-shaped small coaming production line from the blanking portion 2201 of the U-shaped small coaming production line to the port-shaped coaming riveting device 2300.

As shown in fig. 14. In fig. 14, 2901 and 2903 are respectively a state when the U-shaped large coaming is discharged at a discharging position 2101 of the U-shaped large coaming production line and a state when the U-shaped small coaming is discharged at a discharging position 2201 of the U-shaped small coaming production line, and 2902 and 2904 are respectively a state when the U-shaped large coaming and the U-shaped small coaming are riveted or after riveting.

The purpose of the glue-applying of the corner line is to seal the inside and the outside of the refrigerator liner after the port-shaped coaming is riveted with the bottom plate. During the gluing operation, the oral coaming is placed on the oral coaming supporting mechanism 2400 by the sucker manipulator. The structure of the device 2400 is the same as that of the device 2300, and see the detailed description of the device. The manipulator track beam 2500 is spanned above the port-shaped coaming supporting mechanism 2400 and the port-shaped coaming riveting equipment 2300 of the corner line gluing part. The manipulator rail beam 2500 is provided with a sucker manipulator. The two sucker manipulators are arranged on the manipulator track beam 2500, and one sucker manipulator is used for transferring the riveted port-shaped coaming from the port-shaped coaming riveting equipment 2300 to the port-shaped coaming supporting mechanism 2400 of the corner line gluing part.

The four-column frame body supporting mechanism comprises four upright columns which are vertically arranged as shown in fig. 3, 4 and 5. The four upright posts are divided into two upright post groups: the first upright post group and the second upright post group. Each set of upright post group comprises two upright posts with the same height. The upright posts of the first upright post group are higher and are high upright posts 1331, and the two high upright posts 1331 are respectively used for supporting two corners of the U-shaped large coaming; the second column set is shorter and is a short column 1332, and the two short columns 1332 are respectively used for supporting two corners of the U-shaped small coaming. The transverse and longitudinal dimensions of the four-column frame body supporting mechanism are adjustable, so that the refrigerator inner containers with different dimensions can be matched. The four-column frame body supporting mechanism and the cabinet opening table 111 form a riveting processing table of the refrigerator liner. The heights of the four upright posts of the four-column type frame body supporting mechanism are not adjustable, and the height of the cabinet opening table 111 is adjustable, so that the riveting processing table can support refrigerator liners with different heights.

The first upright post group, the riveting mechanism and the second upright post group are sequentially arranged and are positioned on the longitudinal central axis. That is, the riveting mechanism is located between the first column set and the second column set. The two upright posts of the two upright post sets are respectively arranged at two sides of the longitudinal central axis and are symmetrical with the longitudinal central axis. The spacing between the two upright posts of the two upright post sets is the same. The two riveting modules 2 are respectively arranged on two sides of the longitudinal central axis and are symmetrical with the longitudinal central axis. The size of the four-column frame body supporting mechanism is adjustable: the longitudinal distance of the first upright post set relative to the riveting mechanism is adjustable, the longitudinal distance of the second upright post set relative to the riveting mechanism is adjustable, the transverse distance between the two upright posts of the first upright post set is adjustable, and the transverse distance between the two upright posts of the second upright post set is adjustable. The two tall posts 1331 of the first post set are vertically disposed on the first longitudinal translation plate 1313 by a lateral adjustment mechanism. Two short posts 1332 of the second post set are vertically disposed on second longitudinal translation plate 1316 by a lateral adjustment mechanism. The first longitudinal translation plate 1313 and the second longitudinal translation plate 1316 are horizontally mounted on a longitudinal slide rail 1311 parallel to the longitudinal central axis by a slider, and are respectively connected with a longitudinal translation driving mechanism: a first longitudinal translation drive mechanism and a second longitudinal translation drive mechanism. The longitudinal rails 1311 are horizontally mounted on the bottom plate 1300. The bottom plate 1300 is horizontally fixed to the base 110.

The first and second longitudinal translation driving mechanisms are respectively used for driving the first and second longitudinal translation plates 1313 and 1316 to move along the longitudinal central axis. The first longitudinal translation drive mechanism includes a first longitudinal drive motor 1310 and a first longitudinal screw 1312. The first longitudinal screw 1312 is located on the longitudinal centerline and is connected to a first longitudinal drive motor 1310. The first longitudinal screw 1312 is connected to a first longitudinal translation plate 1313 by a wire sleeve. Thus, the first longitudinal driving motor 1310 drives the first longitudinal screw 1312 to rotate, and the first longitudinal translation plate 1313 is driven to translate on the longitudinal slide 1311 by the threaded engagement between the first longitudinal screw 1312 and the wire sleeve at the bottom of the first longitudinal translation plate 1313. The second longitudinal translation drive mechanism includes a second longitudinal drive motor 1314 and a second longitudinal lead screw 1315. A second longitudinal screw 1315 is located on the longitudinal centerline and is connected to a second longitudinal drive motor 1314. The second longitudinal screw 1315 is connected to a second longitudinal translation plate 1316 by a wire sleeve. Thus, the second longitudinal driving motor 1314 drives the second longitudinal screw 1315 to rotate, and the second longitudinal screw 1316 is driven to translate on the longitudinal slide 1311 by the threaded engagement between the second longitudinal screw 1315 and the wire sleeve at the bottom of the second longitudinal translation plate 1316.

The caulking module 2, as shown in fig. 6 and 7, includes a U-shaped frame 21, a caulking cylinder 22, a caulking plate frame 23, a caulking plate 24, and a caulking pad 25. The riveting cylinder 22, the riveting plate frame 23, the riveting plate 24 and the riveting pad 25 are mounted on the U-shaped frame 21. The two riveting modules 2 correspond to the two U-shaped frames 21. Two U-shaped brackets 21 are mounted on a longitudinal fixed plate 1317. Longitudinal fixed plate 1317 is fixed to base plate 1300. When the first longitudinal translation driving mechanism and the second longitudinal translation driving mechanism respectively drive the first longitudinal translation plate 1313 and the second longitudinal translation plate 1316 to move, two upright posts of the first upright post group on the first longitudinal translation plate 1313 and two upright posts of the second upright post group on the second longitudinal translation plate 1316 move relative to the two U-shaped frames 21, so that the whole riveting equipment can adapt to the riveting processing of refrigerator inner container size coamings with different longitudinal sizes.

The U-shaped frame 21, as shown in fig. 6 and 7, includes an outer column frame 211 and an inner column frame 212. The outer column frame 211 is located at the outside and the inner column frame 212 is located at the inside. A rivet gap 213 is provided between the outer column frame 211 and the inner column frame 212. The rivet plate 24 is vertically mounted on the outer column frame 211 with the rivet cylinder 22 through the rivet plate frame 23 and is positioned in the rivet gap 213. Specifically, there are two riveting cylinders 22. Two riveting cylinders 22 are horizontally installed on the outer column frame 211, and two riveting cylinders 22 are placed one above the other. The riveting rack 23 is vertically disposed on the pistons of the two riveting cylinders 22 and is located in the riveting gap 213. The rivet plate 24 is mounted on the rivet plate frame 23. As shown in fig. 8, the caulking plate rack 23 is provided with a vertical trapezoidal clamping groove 231. As shown in fig. 9, the rivet plate 24 is provided with a trapezoidal block 242 along the vertical plate body direction. The trapezoidal clamping block 242 is matched with the trapezoidal clamping groove 231. The rivet plate 24 is fitted to the rivet plate holder 23 by being engaged with the trapezoidal engagement groove 231 by the trapezoidal engagement block 242, and is capable of sliding up and down along the trapezoidal engagement groove 231 in the vertical direction. An adjusting cylinder 241 is mounted on the top end of the rivet plate frame 23. The piston of the adjusting cylinder 241 is connected to the rivet plate 24, so that the rivet plate 24 can be lifted and lowered by the driving of the adjusting cylinder 241. The rivet shim plate 25 is mounted vertically on the inner post 212 within the rivet gap 213. The direction in which the riveting cylinder 22 is erected is perpendicular to the longitudinal central axis, so that the riveting plate 24 can horizontally move in the direction perpendicular to the longitudinal central axis under the drive of the riveting cylinder 22 and can be pressed on the backing plate surface of the riveting backing plate 25, and the riveting of the plate between the large and small coamings is realized.

The two U-shaped brackets 21 of the two riveting modules 2 are arranged vertically on the longitudinal fixing plate 1317 by a transverse adjustment mechanism. And combining the corresponding transverse adjusting mechanisms of the first upright post group and the second upright post group, wherein a total of three transverse adjusting mechanisms are arranged. The transverse adjusting mechanism is used for adjusting the transverse distance and then matching the transverse size of the refrigerator liner. The three transverse adjusting mechanisms are connected with synchronous interval adjusting driving mechanisms. The synchronous pitch adjustment driving mechanism is used for driving the three lateral adjustment mechanisms and synchronizing the lateral pitch adjustment of the three lateral adjustment mechanisms. As shown in fig. 3, 4, 5, 6, and 7, the synchronous pitch adjustment driving mechanism includes a first vertical petal-axis driving mechanism 1301, a second vertical petal-axis driving mechanism 1302, a third vertical petal-axis driving mechanism 1303, a petal axis 1304, and a width adjustment motor 1305. The lateral adjustment mechanism, as shown in fig. 4, includes a lateral lead screw 1321 and a lateral slide rail 1322. Two upright posts of the two upright post sets are respectively vertically erected on the transverse slide rail 1322 through the sliding blocks 1323 at the bottom, and two U-shaped frames 21 are erected on the transverse slide rail 1322 through the sliding blocks 1323 at the bottom. The transverse sliding rails 1322 of the three transverse adjusting mechanisms are respectively and horizontally erected on the first longitudinal translation plate 1313, the longitudinal fixing plate 1317 and the second longitudinal translation plate 1316. The transverse slide 1322 is perpendicular to the longitudinal slide 1311. The transverse screw 1321 is provided with forward and reverse threads, which are parallel to the transverse slide rails 1322. The bottoms of the two columns of the two sets of columns are respectively connected with the forward threads and the reverse threads of the transverse screw rod 1321 through the screw sleeve, so that when the transverse screw rod 1321 rotates, the two columns of the corresponding column sets can be driven to move on the transverse sliding rail 1322 in opposite directions. The two U-shaped frames 21 are respectively connected with the forward thread and the reverse thread of the transverse screw rod 1321 through the wire sleeve, so that the two U-shaped frames 21 can be driven to move on the transverse sliding rail 1322 in opposite directions when the transverse screw rod 1321 rotates. The first, second, and third vertical petal-axis transmission mechanisms 1301, 1302, and 1303 are provided on the petal axis 1304, and are movable along the petal axis 1304. The petal axle 1304 is parallel to the longitudinal rails 1311 and perpendicular to the lateral lead screw 1321 of the lateral adjustment mechanism. The petal axle 1304 is respectively connected with the transverse screw rod 1321 of the three transverse adjusting mechanisms through the first vertical petal axle transmission mechanism 1301, the second vertical petal axle transmission mechanism 1302 and the third vertical petal axle transmission mechanism 1303. The petal shaft 1304 is connected with a width adjusting motor 1305. Thus, when the width adjusting motor 1305 drives the petal shaft 1304 to rotate, the petal shaft 1304 drives the transverse screw 1321 of the three transverse adjusting mechanisms to rotate through the first vertical petal shaft transmission mechanism 1301, the second vertical petal shaft transmission mechanism 1302 and the third vertical petal shaft transmission mechanism 1303, thereby adjusting the transverse distance between the two upright posts of the two upright post sets and simultaneously adjusting the transverse distance between the two U-shaped frames 21. It can be seen that the adjustment of the lateral distance between the two U-shaped brackets 21 is synchronized with the adjustment of the lateral distance between the two uprights of the upright group, and thus the shim plate surfaces of the rivet shim plates 25 on the rivet module 2 can always be kept on the same vertical plane as the outer surfaces of the uprights on the same side. The petal shaft 1304 is the same as the spline shaft in patent document CN 105798180A.

The cabinet opening table 111 is provided with a four-column frame body supporting mechanism and a riveting mechanism and is used for supporting the cabinet opening of the refrigerator liner. The cabinet opening table 111 is horizontally installed on the cabinet opening table lifting mechanism, and is height-adjustable through the cabinet opening table lifting mechanism. The cabinet opening table 111 is provided with four column type frame body supporting mechanisms and riveting mechanisms, namely a plate hole is formed in the cabinet opening table 111, and the four column type frame body supporting mechanisms and the riveting mechanisms respectively penetrate through the corresponding plate holes. The cabinet opening table lifting mechanism is used for driving the cabinet opening table 111 to lift and comprises a chain 112, a motor 113 and four sets of wire rod column sleeve mechanisms. The screw post sleeve mechanism includes a screw sleeve post 121, a screw post 122, a drive gear 123, and two clamping gears 124. The silk fibroin 121 is vertically installed on the base 110. The screw post 122 is vertically disposed within the socket hole of the socket post 121. Four screw rod column sleeve mechanisms are respectively positioned at four corners of the base 110. The cabinet opening table 111 is mounted on the top end of the screw rod column 122 and is horizontally arranged. The cabinet opening table 111 is a square plate body, and four corners of the square plate body respectively correspond to one set of wire rod column sleeve mechanism. A horizontal gear cabinet 125 is mounted on top of the silk sleeve column 121. The drive gear 123 is mounted on the screw post 122 above the gear cabinet 125. Two clamping gears 124 are mounted on the gear cabinet 125 on either side of the drive gear 123. The driving gear 123 can be rotated in synchronization with the screw post 122. When the driving gear 123 rotates, the screw rod 122 is driven to rotate. The rotating screw rod column 122 drives the screw rod column 122 to lift through the screw thread action between the screw rod column 122 and the screw sleeve column 121, so that the cabinet opening table 111 is driven to lift. A motor 113 is mounted on the base 110 and is connected to a drive gear 114. Two transition gears 115 are provided on the table on which the driving gear 114 is mounted. The drive gear 123, the clamping gear 124, the drive gear 114, and the transition gear 115 are all located at the same height. The chain 112 crosses around the drive gear 114, the transition gear 115, the drive gear 123 and the clamping gear 124. Wherein, at the driving gear 114 and the transition gears 115, the chain 112 bypasses the driving gear 114 and the two transition gears 115 so that the chain 112 is in an omega structure and simultaneously meshes with the driving gear 114 and the two transition gears 115. At the drive gear 123 and the clamp gear 124, the chain 112 is clamped between the drive gear 123 and the clamp gear 124, and simultaneously meshes with the drive gear 123 and the clamp gear 124. Therefore, when the motor 113 drives the driving gear 114 to rotate, the chain 112 rotates and moves along with the driving gear, so as to drive the driving gears 123 of the screw rod column sleeve mechanisms to rotate, and the cabinet opening table 111 is driven to lift by the threaded engagement action between the screw rod column 122 and the screw sleeve column 121.

Further, in the present embodiment, the U-shaped frame 21 is composed of an L-shaped frame and an outer column frame 211 mounted on the L-shaped frame. Wherein, as shown in fig. 11, the L-shaped frame is composed of two mutually parallel and vertical L-shaped plates 219 and a transverse supporting beam between the two L-shaped plates 219. The vertical portion of the L-shaped frame is the inner post frame 212. The outer column frame 211 is mounted on a horizontal portion of the L-shaped frame. The outer column frame 211 is composed of two side frame plates which are parallel to each other and are vertically arranged, and a transverse supporting beam between the two side frame plates. The riveting cylinder 22 is arranged between two parallel side frame plates of the outer column frame 211. With this structure, the physical strength between the outer column frame 211 and the inner column frame 212 appears to be insufficient. When the rivet plate 24 is driven by the rivet cylinder 22 to press against the rivet plate 25, the outer column frame 211 is easily displaced rearward, resulting in uneven pressure on the rivet plate 25 by the rivet plate 24. In order to strengthen the physical strength between the outer column frame 211 and the inner column frame 212, in the present embodiment, as shown in fig. 13, a U-shaped reinforcing plate 214 is installed between both sides of the bottoms of the outer column frame 211 and the inner column frame 212. The U-shaped reinforcing plates 214 are respectively arranged on the front and rear surfaces of the U-shaped frame 21.

In addition, in this embodiment, since the columns of the first column group and the second column group are mounted on the lateral and longitudinal slide rails, physical strength is easily insufficient, and when the rivet plate 24 performs riveting, column yield of the first column group and the second column group is easily caused. For this reason, in this embodiment, a reinforcement mechanism is provided between two columns of the first column group and the second column group. The reinforcement mechanism, as shown in fig. 5, includes a reinforcement plate 1341. The reinforcement panel 1341 is vertically mounted on either the first or second longitudinal translation panel and is perpendicular to the longitudinal central axis. The reinforcement plate 1341 is provided with a horizontal reinforcement slide rail 1342. The reinforcement sled 1342 is perpendicular to the longitudinal central axis. The two upright posts of the first upright post group and the second upright post group are respectively connected with a reinforced sliding rail 1343 through a reinforced sliding block 1343.

In addition, in the present embodiment, the riveting plate 24 is a strip-shaped plate body, and is vertically arranged along the strip-shaped direction, and is driven by the upper and lower riveting cylinders 22. The problem of uneven thrust force easily occurs in the two riveting cylinders 22. When the thrust forces of the upper and lower caulking cylinders 22 are uneven, the pressure of the caulking plate 24 against the caulking pad 25 is easily uneven when caulking is caused. For this purpose, in the present embodiment, an up-down balance mechanism 26 is further provided between the outer column frame 211 and the caulking plate frame 23. The up-down balancing mechanism 26, as shown in fig. 10, includes a rack 261 and a synchronizing shaft 262. The synchronizing shaft 262 is vertically disposed, and upper and lower ends are respectively mounted on the outer column frame 211 through two bearing plates 264. Two bearing plates 264 at the upper and lower ends of the synchronizing shaft 262 respectively hold two gears 263 of the same specification. The gear 263 is mounted on the synchronizing shaft 262 and can rotate in synchronization with the synchronizing shaft 262. The racks 261 have two. The two racks 261 are arranged horizontally and perpendicular to the aforementioned longitudinal central axis. The two racks 261 are of the same size, are clamped between the two bearing plates 264 at the upper and lower ends of the synchronizing shaft 262, and are clamped between the side frame plate of the outer column frame 211 and the gear 263, and can move horizontally relative to the side frame plate of the outer column frame 211. The rack 261 is meshed with the gear 263. One end of the rack 261 is fixed to the caulking plate frame 23.

In this embodiment, the caulking pad 25 is a flat plate. As shown in fig. 9, a vertical caulking groove 243 is provided on a caulking face of the caulking plate 24 facing the caulking pad 25. The U-shaped large coaming produced by the U-shaped large coaming production line and the U-shaped small coaming produced by the U-shaped small coaming production line are provided with 135-degree angle folds at the end line of the combination of the U-shaped large coaming and the U-shaped small coaming. When in riveting, the 135-degree folded edges of the U-shaped large coaming and the 135-degree folded edges of the U-shaped small coaming are clamped in a staggered manner, and the riveting part 299 of the four-layer structure shown in fig. 13 is formed after the riveting plate 24 and the riveting base plate 25 are pressed. The rivet 299 is also known as rivet lines L1 and L2 in fig. 14. Since the vertical caulking groove 243 is provided in the caulking plate 24, when the caulking plate 24 and the caulking pad 25 are caulked, the caulking portion 299 of the four-layer laminated structure protrudes outward through the caulking groove 243. Since the caulking pad 25 is a flat plate on the inner side of the caulking portion 299, the caulking portion 299 is flush with the plate bodies on both sides, and thus the inside of the refrigerator liner is free from or has only a small trace of the caulking portion 299.
