Description

Technical Field

[0001] The present invention relates to an automated loading and unloading technology, and specifically to an automated loading and unloading device for injection molding of lithium battery covers. Background Art

[0002] The lithium battery cover is composed of several parts such as a pole column, a lower plastic, and a light aluminum sheet. Before the pole column is assembled with other parts, a sealing ring needs to be sleeved on it. When the lithium battery cover needs to be injection molded, the above-mentioned several parts are manually loaded in sequence into the lower mold of the injection molding machine to assemble the lithium battery cover. Then, wait for the injection molding process. After the injection molding is completed, the completed injection molded lithium battery cover is taken away from the lower mold of the injection molding machine by manual. It can be seen that the process of loading the parts of the lithium battery cover into the lower mold of the injection molding machine in sequence for assembly and the process of taking away the completed injection molded lithium battery cover to achieve unloading completely rely on manual labor, resulting in high manual labor intensity and prone to mistakes in manual operations, and it is not easy to guarantee the quality of the product.

Between the two groups of tray stacking areas 202, there are two groups of tray translation guiding bars 212 laid along the length directions of the two horizontal support bars 201. When the area formed by the four groups of vertical guiding and limiting arms 203 is used for stacking trays 213, it becomes a limiting groove that restricts the offset of the trays 213 when stacked on the horizontal support bar 201. The vertical guiding and limiting arm 203 is a guiding and limiting structure composed of two L-shaped guiding plates;

The nut seat 216 is threadedly connected to the lead screw 215 and a vertical guide rod 219 is provided on its body. A vertical guide sleeve 220 slidably connected to the vertical guide rod 219 is provided on the mounting plate 218. The top rod 217 is vertically arranged on the nut seat 216 and its top end penetrates the upper end surface of the second body 200. A top block 221 is provided at the top end of the top rod 217. A fixed seat 222 is provided on the upper end surface of the second body 200.

And an inner groove for accommodating the layer separation plug 225 is provided on the horizontal support bar 201. When the layer separation plug 225 is in the inner groove, its top surface is lower than the upper end surface of the horizontal support bar 201.

[0115] There are multiple stacked trays at the tray stacking area 202. When feeding is required, the tray clamping mechanism moves towards the tray stacking area 202 under the horizontal driving action of the conveyor belt 204 and moves to directly below the multiple stacked trays 213. Then, the clamping plates 207 at the two sets of clamping components in the tray clamping mechanism move upward under the drive of the corresponding clamping plate driving cylinders 208 and can respectively clamp on both side surfaces of the first-layer tray 213. Then, the vertical movement driving component and the insertion plate driving component in the tray layer separation mechanism start to work respectively. First, the servo motor 214 in the vertical movement driving component drives the lead screw 215 to rotate, which can make the nut seat 216 move upward, so that the ejector rod 217 pushes the top block 221 upward, thereby making the entire insertion plate driving component move upward, so that the horizontal height of the layer separation insertion plate 225 in the insertion plate driving component is flush with the horizontal height of the gap between the first-layer and the second-layer trays 213. Then, the layer separation insertion plate 225 is driven by the insertion plate driving cylinder 224 to insert between the first-layer and the second-layer trays 213 to realize the layer separation of the trays 213 and lift the multiple trays. Then, the tray conveyor belt 204 drives the tray clamping mechanism to move along the guidance of the linear slide rail 205 to the two sets of tray translation guiding strips 212, so that the tray 213 clamped by the clamping plates 207 at the two sets of clamping components moves to the two sets of tray translation guiding strips 212. Then, the servo motor 214 in the vertical movement driving component drives the lead screw 215 to reverse, and the entire insertion plate driving component moves downward, and the layer separation insertion plate 225 moves downward into the inner groove of the horizontal support bar 201. The remaining multiple trays 213 at the tray stacking area 202 are stacked on the horizontal support bar 201. The first pole taking manipulator 3 installed on the second body 200 grabs the poles on the tray 213 located between the two sets of tray translation guiding strips 212 and transfers the poles to the first pole conveyor belt 4. After the poles on the tray 213 are taken out, the clamping plate driving cylinder 208 drives the clamping plate 207 to move downward, no longer clamping the empty tray 213, but continuing to repeat the above actions, continuing to move to the tray stacking area 202 to re-clamp the tray 213 filled with poles, and the empty tray 213 is taken away by the manipulator or manually.

[0116] In this embodiment, the pole alignment mechanism A5 includes an I-shaped frame 500, a pole alignment component A, an upper top double-axis cylinder A503, and a top column A504;

[0118] The pole alignment component A includes a square positioning seat A501, an alignment positioning strip A502, and two sets of translation positioning components A;

[0119] The square positioning seat A501 is arranged on the top surface of the upper web of the I-shaped frame 500. The top surface of the square positioning seat A501 is used to carry the pole column transferred here by the second pole column picking manipulator 7. There are two groups of alignment positioning bars A502, which are distributed in an L shape at two adjacent sides of one group of the square positioning seat A501. The two groups of alignment positioning bars A502 respectively abut against the corresponding two sides of the pole column placed on the square positioning seat A501.

[0120] The two groups of translation positioning components A are both arranged on the top surface of the upper web of the I-shaped frame 500 and are respectively adjacent to the two adjacent sides of the other group of the square positioning seat A501. The translation positioning component A includes a slide rail seat A505, a positioning slide rail A506, a positioning slider A507, a fixed block A508, a return spring A509, and a return roller A510.

[0121] The slide rail seat A505 is arranged on the top surface of the upper web of the I-shaped frame 500. The positioning slide rail A506 is arranged on the slide rail seat A505. The positioning slider A507 is slidably connected to the positioning slide rail A506.

The fixed block A508 is arranged on the top surface of the upper web of the I-shaped frame 500 and is adjacent to the side of the positioning slider A507 far from the square positioning seat A501. The return spring A509 is arranged between the fixed block A508 and the positioning slider A507. The elastic force of the return spring A509 can drive the positioning slider A507 to slide along the guidance of the positioning slide rail A506 and approach the adjacent side of the square positioning seat A501, and abut against the corresponding two sides of the pole column placed on the square positioning seat A501. The return roller A510 is arranged on the side surface of the positioning slider A507. The horizontal tangent direction when the return roller A510 rolls is parallel to the guidance of the positioning slide rail A506.

[0122] The upper top double-axis cylinder A503 is arranged between the upper and lower webs of the I-shaped frame 500 through a support. The top column A504 is vertically arranged in the notch provided on the upper web of the I-shaped frame 500, and the lower end is connected to the piston end of the upper top double-axis cylinder A503. There are two groups of inclined surfaces at the top end of the top column A504. The two groups of inclined surfaces at the top end of the top column A504 are respectively in rolling contact with the return rollers A510 in the two groups of translation positioning components A.

[0123] Before the second pole taking manipulator 7 sends the pole grabbed from the first pole conveyor belt 4 to the square positioning seat A501 in the pole alignment component A, the upper top double-shaft cylinder A503 drives the ejector post A504 to rise. The two sets of inclined surfaces at the top of the ejector post A504 can respectively force the corresponding reset rollers A510 in the two sets of translation positioning components A to move away from the square positioning seat A501, so that the positioning sliders A507 in the two sets of translation positioning components A overcome the elastic force of the corresponding reset springs A509 and move away from the square positioning seat A501. After the second pole taking manipulator 7 sends the pole to the square positioning seat A501, the upper top double-shaft cylinder A503 drives the ejector post A504 to move down. The positioning sliders A507 in the two sets of translation positioning components A approach the square positioning seat A501 under the action of the elastic force of the reset springs A509 and lean against the other two adjacent sides of the pole placed on the square positioning seat A501. Combining with the positioning effect of the two sets of alignment positioning bars A502, the first alignment positioning of the pole is realized.

[0126] The material receiving station component includes a base plate 602 arranged on the upper end surface of the material receiving turntable 601 and four groups of positioning plates 603 arranged in a square on the base plate 602. A first guide wheel 604 is erected on the upper end of the positioning plate 603. The base plate 602 is used to receive the pole, the positioning plate 603 is used to limit the position of the pole on the base plate 602, and the first guide wheel 604 is arranged to facilitate the pole to smoothly fall into the range defined by the four groups of positioning plates 603.

[0127] When the second pole taking manipulator 7 sends the pole that has been aligned in the pole alignment mechanism A5 to the range defined by the four groups of positioning plates 603 in the adjacent material receiving station component on the multi-station rotary material receiving plate mechanism 6 in the static and stopped rotation state, it also synchronously sends the pole at the conveying end of the first pole conveyor belt 4 to the square positioning seat A501 in the pole alignment mechanism A5 in the vacant state.

[0128] During the working process, when the receiving turntable 601 in the multi-station rotary material receiving tray mechanism 6 is in a stationary and non-rotating state, the second pole picking manipulator 7, the seal ring sleeving device, and the third pole picking manipulator 8 work synchronously. They respectively send the properly aligned poles in the pole alignment mechanism A5 to adjacent workstations in the multi-station rotary material receiving tray mechanism 6, sleeve the seal rings on the poles at adjacent workstations in the multi-station rotary material receiving tray mechanism 6, and grasp the poles with seal rings sleeved at adjacent workstations in the multi-station rotary material receiving tray mechanism 6. After these operations are completed, the first indexing rotary table 600 in the multi-station rotary material receiving tray mechanism 6 will drive the receiving turntable 601 to start rotating, rotating by one workstation angle, so that the second pole picking manipulator 7, the seal ring sleeving device, and the third pole picking manipulator 8 are respectively adjacent to another set of receiving workstation components, and then a new round of synchronous work is carried out.

At the bottom of the movable support 2026, there are provided a sleeve seal column 2029 with a vertical axis and a seal-pushing cylinder 2030. The sleeve seal column 2029 is used to insert into the inner ring of the seal accommodated in the U-shaped positioning groove of the seal, so that the seal is sleeved on the outer periphery of its body. A seal-pushing bushing 2031 is sleeved on the outer periphery of the seal column 2029.

The buffer spring 2036 is sleeved on the horizontal connecting rod 2035. The two ends of the buffer spring 2036 respectively abut against the shoulder and the angle steel connector 2034. Through the elastic force of the buffer spring 2036, the impact force when the piston end of the power push rod 2022 extends can be reduced.

[0140] As the seal ring vibrating disk 2000 starts to work, the seal rings inside the seal ring vibrating disk 2000 move along the guidance of the seal ring chute 2001 and enter the seal ring guiding groove 2004. Then, the vertical driving cylinder 2012 drives the seal ring positioning rod 2013 to move upward, moving into the seal ring guiding groove 2004 and protruding from the top slot of the seal ring guiding groove 2004. Then, the horizontal driving cylinder 2010 starts to drive, prompting the L-shaped sliding seat 2009 to move towards the seal ring limiting plate 2005, so that the seal ring positioning rod 2013 horizontally pulls the seal ring in the seal ring guiding groove 2004 to move from the seal ring guiding groove 2004 into the seal ring U-shaped positioning groove in the seal ring limiting plate 2005. The seal ring positioning rod 2013 pulls the seal ring to the designated position. At this time, the seal ring completely enters and just fully fits into the seal ring U-shaped positioning groove. Then, the material blocking assembly starts to work. Driven by the material blocking cylinder 2016, the material blocking bar 2017 horizontally inserts into the gap between the seal ring guiding groove 2004 and the seal ring limiting plate 2005, forming a block for the subsequent seal rings entering the seal ring guiding groove 2004, completely separating the subsequent seal rings entering the seal ring guiding groove 2004 from the seal ring in the seal ring U-shaped positioning groove, so as to ensure that the seal ring in the seal ring U-shaped positioning groove will not be pushed out of the seal ring U-shaped positioning groove by the subsequent seal rings entering the seal ring guiding groove 2004 after the seal ring positioning rod 2013 is removed. Then, the vertical driving cylinder 2012 and the horizontal driving cylinder 2010 are driven in sequence to make the seal ring positioning rod 2013 return to its original position and wait for the next operation. Then, the seal ring transfer assembly starts to work. The lifting cylinder 2032 drives the vertical sliding block seat 2020 to move downward through the L-shaped part 2033, so that the seal ring sleeve column 2029 at the bottom end of the moving support 2026 inserts into the inner ring of the seal ring accommodated in the seal ring U-shaped positioning groove, making the seal ring sleeve on its outer periphery. Then, the lifting cylinder 2032 drives the vertical sliding block seat 2020 to move upward through the L-shaped part 2033, so that the seal ring accommodated in the seal ring U-shaped positioning groove is taken away by the seal ring sleeve column 2029. Immediately afterwards, the material blocking cylinder 2016 drives the material blocking bar 2017 to retract. The subsequent seal rings entering the seal ring guiding groove 2004 are pulled into the seal ring U-shaped positioning groove under the new operation of the seal ring positioning rod 2013. At the same time, the power push rod 2022 drives the horizontal sliding plate 2024 to translate along the guidance of the horizontal guide rail groove 2021 towards the adjacent material receiving station assembly on the multi-station rotary material receiving disk mechanism 6 through the buffer assembly, so that the seal ring sleeve column 2029 drives the seal ring to translate towards the adjacent material receiving station assembly on the multi-station rotary material receiving disk mechanism 6. The seal ring sleeve column 2029 reaches directly above the pole column placed within the range defined by the four sets of positioning plates 603 in the adjacent material receiving station assembly on the multi-station rotary material receiving disk mechanism 6. Then, the lifting cylinder 2032 drives the vertical sliding block seat 2020 to move downward through the L-shaped part 2033, making the lower end surface of the seal ring sleeve column 2029 close to the top surface of the pole column.To maintain a very small gap, the push seal ring cylinder 2030 is then used to drive the push seal ring bushing 2031 downward, so that the seal ring sleeved on the seal ring column 2029 is detached from its body and sleeved on the terminal post. Then, the push seal ring cylinder 2030 drives the push seal ring bushing 2031 upward. Then, driven by the jacking cylinder 2032 and the power push rod 2022, the seal ring column 2029 returns to its original position, and the above work is repeated. After the seal ring sleeving device completes the work of sleeving the seal ring on the terminal posts of the adjacent material receiving station components on the multi-station rotary material receiving plate mechanism 6 in a stationary and stopped state, the first indexing rotary worktable 600 in the multi-station rotary material receiving plate mechanism 6 will drive the material receiving turntable 601 to rotate by a station angle, so that another group of material receiving station components are adjacent to the seal ring sleeving device, and then the seal sleeving work is carried out again.

[0141] After the terminal posts on the material receiving station components of the multi-station rotary material receiving plate mechanism 6 are sleeved with seal rings, the third terminal post picking manipulator 8 in the terminal post transfer device grabs the terminal posts with seal rings sleeved on the adjacent material receiving station components in the multi-station rotary material receiving plate mechanism 6 and transfers them to the second terminal post conveyor belt 9 in the terminal post transfer device. Then, the combined picking manipulator 14 in the combined positioning device takes away the terminal posts on the second terminal post conveyor belt 9.

The station bottom plate 1003 is arranged on the upper end surface of the feeding turntable 1002, the lower plastic limiting groove 1004 is a long groove with an I-shaped cross section, which is vertically arranged on the upper end surface of the station bottom plate 1003, the lower plastic support plate 1005 has two groups and is symmetrically located at the two groups of limiting concave cavities on the lower plastic limiting groove 1004, and there are two groups of support plate guide rails 1006, the two groups of support plate guide rails 1006 are vertically arranged on the upper end surface of the station bottom plate 1003 and are respectively adjacent to the two groups of lower plastic support plates 1005, and the support plate guide rails 1006 are slidably provided with a support plate slider 1007 connected to the adjacent lower plastic support plate 1005, and there are two groups of threading positioning rods 1008, and the two groups of threading positioning rods 1006 are respectively adjacent to the two groups of lower plastic support plates 1005. 008 are vertically arranged on the upper end surface of the workstation bottom plate 1003, two sets of material threading positioning rods 1008 vertically penetrate the two sets of lower plastic support plates 1005 respectively, the material threading positioning rods 1008 are adapted to the material holes on the lower plastic body, and the two sets of material threading positioning rods 1008 vertically penetrate the material holes on the lower plastic body stacked on both sides of the lower plastic limiting groove 1004 respectively, which can prevent the position from deviating when stacking, and there are two sets of force rods 1009, two sets of force rods 1009 are vertically arranged on the lower end surface of the lower plastic support plate 1005, and the force rods 1009 vertically penetrate the workstation bottom plate 1003 and the feeding turntable 1002 and protrude from the lower end surface of the feeding turntable 1002;

[0145] There are two groups of ejector assemblies, both of which are arranged on the lower end surface of the top plate of the third body 1000. The ejector assemblies include a through-axis linear stepper motor 1010, an ejector screw 1011, a screw guide rail 1012, a screw guide block 1013, and a wear-resistant block 1014. The through-axis linear stepper motor 1010 is arranged on the lower end surface of the top plate of the third body 1000. The ejector screw 1011 passes through the rotor center of the through-axis linear stepper motor 1010. The top of the ejector screw 1011 passes through the rotor center of the through-axis linear stepper motor 1010. The top plate of the third body 1000 is passed through and is provided with a wear-resistant block 1014. The top material screws 1011 in the two groups of top material assemblies are axially overlapped with the two groups of force-bearing rods 1009 in any group of lower plastic feeding stations on the feeding turntable 1002 in a stationary state. The screw guide rail 1012 is vertically placed on the lower end surface of the top plate of the third body 1000. The screw guide block 1013 is slidably connected to the screw guide rail 1012, and the screw guide block 1013 is rotatably connected to the bottom end of the top material screw 1011 through a bearing.

[0146] On both sides of the lower plastic limiting groove 1004 at the lower plastic feeding station, multiple layers of lower plastics are stacked. When the lower plastic feeding mechanism starts feeding, the feeding turntable 1002 is in a static and stopped rotating state. The lower plastic picking manipulator 11 mounted on the third body 1000 starts to pick up the lower plastics stacked on both sides of the lower plastic limiting groove 1004 in the adjacent lower plastic feeding station. Every time one layer is picked up, the two groups of ejector components start synchronous operation once. The through-axis linear stepper motor 1010 drives the ejector lead screw 1011 to rotate and rise by a height along the lead screw guide 1012. The wear-resistant block 1014 at the top of the ejector lead screw 1011 pushes the corresponding force rod 1009 to rise by a height, so that the multiple layers of lower plastics stacked on both sides of the lower plastic limiting groove 1004 rise by a height under the lifting of the corresponding lower plastic support plate 1005. The height of each rise is the thickness of a single layer of lower plastic until all the multiple layers of lower plastics stacked on both sides of the lower plastic limiting groove 1004 are picked up by the lower plastic picking manipulator 11. Then, the through-axis linear stepper motor 1010 drives the ejector lead screw 1011 to rotate and descend to the lowest point along the lead screw guide 1012. Then, the second indexing rotary table 1001 drives the feeding turntable 1002 to rotate by a station angle, making another group of lower plastic feeding stations adjacent to the lower plastic picking manipulator 11, and then a new round of lower plastic picking work is started. Each time the lower plastic picked up by the lower plastic picking manipulator 11 is transferred to the lower plastic conveyor belt 12, and then the combined picking manipulator 14 in the combined positioning device picks up the lower plastics on the lower plastic conveyor belt 12.

[0147] The combined picking manipulator 14 transfers the pole columns with gaskets sleeved thereon grabbed from the second pole column conveyor belt 9, the lower plastics grabbed from the lower plastic conveyor belt 12, and the light aluminum sheets grabbed from the light aluminum sheet discharge conveyor belt 13 to the combined positioning mechanism 5 for positioning respectively.

[0148] In this embodiment, the combined positioning mechanism 15 includes a sealed electric slide 1500 provided on the upper end surface of the first body 1, a pole column positioning mechanism B provided on the translation end surface of the sealed electric slide 1500, and a combined positioning component for combining and positioning the lower plastics and the light aluminum sheets;

[0149] Specifically, the pole positioning mechanism B includes a first positioning base plate 1501. The first positioning base plate 1501 is horizontally arranged on the translation end face of the sealed electric slide 1500 through a column. Multiple groups of pole alignment components B with the same structure as the pole alignment component A are provided on the first positioning base plate 1501. Below the first positioning base plate 1501, a top column support plate 1502 and an upper top double-shaft cylinder B1503 are successively arranged from top to bottom.

Multiple groups of top columns B1504 with the same structure as the top column A504 are provided on the upper end face of the top column support plate 1502. The tops of multiple groups of top columns B1504 vertically penetrate the first positioning base plate 1501, and the tops of multiple groups of top columns B1504 respectively cooperate with multiple groups of pole alignment components B. The two inclined surfaces at the top of the top column B1504 are in contact and cooperation with the two reset rollers in the corresponding pole alignment component B.

[0150] Before the pole alignment component B aligns the pole, the upper top double-shaft cylinder B1503 drives the top column support plate 1502 to move upward, so that multiple groups of top columns B1504 cause the two reset rollers in the corresponding pole alignment component B to move. When the pole alignment component B performs the second alignment and positioning on the pole with the seal ring already sleeved, the working principle and process are the same as those when the pole alignment component A performs the first alignment and positioning on the pole. Therefore, it will not be elaborated here. When the combined material-taking manipulator 14 transfers the pole with the seal ring already sleeved grabbed from the second pole conveyor belt 9 to the pole alignment component B, since the working principle and process of the pole alignment component B and the pole alignment component A for aligning and positioning the pole are the same, after the upper top double-shaft cylinder B1503 drives the top column support plate 1502 to move downward, causing the top column B1504 to also move downward, the second alignment and positioning of the pole by the pole alignment component B is achieved.

[0151] Specifically, the combined positioning component includes a second positioning base plate 1505.

A support strip 1510 with the same height as the loading boss 1509 is provided at the gap between the side of the square loading plate 1508 far from the loading boss and the adjacent positioning strip 1506. The top surfaces of the loading boss 1509 and the support strip 1510 constitute a support plane for supporting the light aluminum sheet in the square limiting area, realizing the positioning of the light aluminum sheet. The second guide wheels 1507 facilitate the smooth entry of the light aluminum sheet into the square limiting area. A first lower plastic positioning block 1511 is slidably provided on the second positioning base plate 1505. The first lower plastic positioning block 1511 is abutted against the side of the lower plastic through translation.

A top block support plate 1520 and an upper top double-axis cylinder C 1521 are successively provided from top to bottom below the second positioning base plate 1505. The upper top double-axis cylinder C 1521 is arranged on the translation end face of the sealed electric slide 1500, and its piston end is connected to the lower end surface of the top block support plate 1520. Multiple groups of top blocks 1522 that respectively cooperate with the first return roller C 1515 and the second return roller C 1519 at multiple groups of combined positioning grooves are provided on the upper end surface of the top block support plate 1520. Two groups of inclined surfaces that respectively cooperate with the first return roller C 1515 and the second return roller C 1519 are provided on the top block 1520.

[0152] The combined material-taking manipulator 14 conveys the lower plastic grabbed from the lower plastic conveyor belt 12 and the light aluminum sheet grabbed from the light aluminum sheet discharging conveyor belt 13 to the combined positioning mechanism in the combined positioning mechanism 5 for positioning. First, the combined material-taking manipulator 14 places the lower plastic in front of the placement area of the lower plastic. The upper double-axis cylinder C1521 drives the top block support plate 1522 to move upward, so that the two groups of inclined surfaces on the top block 1522 are tangent to the outer circles of the first reset roller C1515 and the second reset roller C1519 respectively, and the first reset roller C1515 and the second reset roller C1519 are translated. Then the corresponding first connecting rod 1514 and the second connecting rod 1518 also drive the corresponding lower plastic first positioning block 1511 and the lower plastic second positioning block 1516 away from the placement area of the lower plastic. At this time, the combined material-taking manipulator 14 places the lower plastic in the placement area of the lower plastic. Then, when the upper double-axis cylinder C1521 drives the top block support plate 1522 to move downward, under the elastic force of the first reset spring C1513 and the second reset spring C1517, the lower plastic first positioning block 1511 and the lower plastic second positioning block 1516 approach the placement area of the lower plastic, and are respectively abutted against the two side surfaces of the lower plastic placed in the placement area, realizing the positioning of the lower plastic.

[0153] After the lower plastic is positioned, the combined material-taking manipulator 14 places the light aluminum sheet above the lower plastic, specifically in the square limiting area surrounded by a plurality of positioning strips 1506 that match the shape of the light aluminum sheet. The top surfaces of the loading boss 1509 and the support strip 1510 serve as the support planes for supporting the light aluminum sheet, realizing the positioning of the light aluminum sheet.

[0154] In this embodiment, the first pole-taking manipulator 3, the second pole-taking manipulator 7, the third pole-taking manipulator 8, the lower plastic-taking manipulator 11, the combined material-taking manipulator 14, and the blanking manipulator 18 are all conventional manipulators, and all include a horizontal driving component and a vertical driving component.

The structure of the second pole-taking manipulator 7 is as Figure 26 shown.

[0157] On the first pole column conveyor belt 4, two sets of guide plates are symmetrically arranged along its horizontal transmission direction. The gap between the two sets of guide plates forms a guiding groove for the pole column during the conveyance on the first pole column conveyor belt 4, preventing the pole column from shifting, enabling multiple sets of pole columns to be arranged in a straight line on the first pole column conveyor belt 4, and facilitating the picking of the pole columns by the first pole column picking manipulator 3.
