The storage warehouse needs to have good structural strength and heat preservation capacity, so the constituent parts of the storage warehouse have high material property requirements and size accuracy requirements. Among them, a V-shaped workpiece in the form of a long V-shaped block, also known as a two-faced workpiece, is used in a polygonal storage warehouse. This V-shaped workpiece has a stacked structure, and its production process is very complicated. Roughly as follows: first, two polyurethane foam plates with one side at an angle are assembled and attached to form a V-shaped body at an operation table, then the V-shaped body is transferred to a glue application table, a layer of V-shaped components is glued and attached at the inside corner, and then it is sent to a press for pressing to make the glue solidify. The V-shaped components are firmly bonded at the inside corner of the V-shaped body, and the above steps are repeated to bond at least two layers of V-shaped components. Then the semi-finished workpiece is transported to a turnover machine for overall turnover, and then the turned semi-finished workpiece is sent to another glue application table to glue and attach multiple bent back corner components at the outside corner (back corner) of the V-shaped body, and then it is sent to another press for pressing. Finally, the finished product is packaged. As can be seen, the production process of the workpiece has many steps, and multiple transfers and overall turnover are required.

[0029] <Embodiment I>

[0030] The embodiment provides a multi-layered V-shaped workpiece batch bonding assembly production line for mass production of the V-shaped workpiece.

[0031] Figure 9 is a side view of the V-shaped workpiece in the prior art, which is a view from one end of the length direction of the V-shaped workpiece.

[0032] As shown in Figure 9 , the V-shaped workpiece comprises a V-shaped body 2000, a plurality of first V-shaped components 2010, a plurality of second V-shaped components 2011, and a plurality of back corner components 2012.

[0033] The V-shaped body 2000 is in the shape of a long strip block, and the cross section in the length direction is in the shape of a V. The V-shaped body 2000 is formed by combining two base plates 2001 in the shape of long strip plates and a partition plate. The base plate 2001 is a polyurethane foam plate with uniform thickness, and one side in the width direction is inclined with respect to the width direction. The inclined side surfaces of the two base plates 2001 are combined in opposite directions, and the partition plate is a wooden plate with relatively thin thickness, which is embedded between the inclined side surfaces of the two base plates 2001 and is fixed by adhesive. The inner side of the V-shaped body 2000 is called a female corner, and the outer side is called a male corner.

[0034] The first V-shaped component 2010 is in the shape of a V-shaped block and is a wooden piece. The bending angle of the first V-shaped component 2010 is consistent with the bending angle of the V-shaped body 2000, and the size of the first V-shaped component 2010 is much smaller than that of the V-shaped body 2000. The first V-shaped component 2010 is installed at the female corner of the V-shaped body 2000 and is fixed by adhesive. A plurality of first V-shaped components 2010 are arranged in sequence along the length direction of the V-shaped body 2000, and there is a gap between adjacent two first V-shaped components 2010.

[0035] The second V-shaped component 2011 is in the shape of a V-shaped plate and is a metal piece. The second V-shaped component 2011 is installed on each first V-shaped component 2010 and is fixed by corresponding fasteners (bolts), and covers the inner side (female corner) surface and part of the side surface of the corresponding first V-shaped component 2010.

[0036] The back corner component 2012 is in the shape of a bent plate and is a metal piece. The cross section in the length direction of the back corner component 2012 is in the shape of a V with a flat tip. The bending angle of the back corner component 2012 corresponds to the bending angle of the V-shaped body 2000. The size of the back corner component 2012 is smaller than the size of the outer side (male corner side) of the V-shaped body 2000. The back corner component 2012 is wrapped on the male corner (back corner) of the V-shaped body 2000 and is fixed by adhesive.

[0037] In addition, the overall size of the V-shaped workpiece is large, and the weight is heavy. The included angle between the two base plates 2001 of the V-shaped workpiece has multiple angles, which are used to form storage bins of different polygonal shapes, such as 90° and 135°.

[0038] Figure 1 is a layout schematic diagram of the batch bonding and assembling production line of the multi-layered V-shaped workpiece in this embodiment.

[0039] As shown in Figure 1 , the production line includes: a plurality of fixed processing devices, a transverse transfer device, a plurality of inside corner pallets, a plurality of outside corner pallets, and a plurality of packaging pallets.

[0040] The transverse transfer device 1010 includes a transverse track 1011 extending in the transverse direction, two transverse trolleys 1012 movably arranged on the transverse track 1011, and a longitudinal transfer mechanism 1013 arranged on the top of the transverse trolleys 1012. In this embodiment, the transverse trolley 1012 is an AGV trolley. The longitudinal transfer mechanism 1013 is a chain type conveying mechanism, which includes a longitudinal drive motor, a driving gear connected with the motor, a driven gear, a connecting rod, and two chains. The upper part of the chain is a longitudinal horizontal section, and the pallet can be placed on the two chains. Under the drive of the longitudinal drive motor and the driving of the connecting rod, the two chains can rotate synchronously, so as to transfer the pallet in the longitudinal direction.

[0041] Each fixed processing device also has a longitudinal transfer mechanism. When the transverse trolley 1012 moves along the track to be roughly aligned with a fixed processing device in the longitudinal direction, the longitudinal transfer mechanism 1013 of the trolley is roughly aligned with the longitudinal transfer mechanism of the fixed processing device in the longitudinal direction, and the distance between them is less than half the length of the bottom of the pallet. The chains of the two rotate in the same direction at substantially the same speed, so as to transfer the pallet from one longitudinal transfer mechanism to the other.

[0042] A plurality of fixed processing devices are arranged on both sides of the transverse track 1011, and are arranged in two rows in sequence on both sides of the track. The fixed processing device includes: a plurality of transition devices, a plurality of assembling devices, a plurality of gluing and pasting devices, a plurality of inside corner pressing devices, a plurality of outside corner pressing devices, and a turnover device.

[0043] The transition device is used to temporarily store the empty tray or the tray with the semi-finished product after pressing, so that the semi-finished product after pressing can be placed for a predetermined aging time. After the pressing by the press and the aging for a certain time, the V-shaped assembly and the back corner assembly can be firmly bonded to the V-shaped body. The transition device includes a first transition device 1001-1, a second transition device 1001-2, and a third transition device 1001-3. The first transition device 1001-1 is used for aging the semi-finished product after the first V-shaped assembly 2010 is pasted and pressed. The second transition device 1001-2 is used for aging the semi-finished product after the second V-shaped assembly 2011 is further pasted and pressed. The third transition device 1001-3 is used for aging the semi-finished product after the back corner assembly 2012 is further pasted and pressed.

[0044] The assembling device 1002 is used for assembling two base plates 2001 and a partition plate to form the V-shaped body 2000. In this embodiment, the assembling device 1002 further includes an assembling table and a mechanical arm arranged on one side of the assembling table. The assembling table has a groove for assembly. The mechanical arm is used to grab two base plates 2001 (polyurethane foam plates) from a specified position, place them on the assembling table, and arrange them in a V shape. Then, the mechanical arm grabs the partition plate and inserts it between the two base plates 2001. Then, the mechanical arm grabs the corresponding connecting assembly to fix the two base plates 2001, thereby forming the V-shaped body 2000. Then, the mechanical arm places the V-shaped body on the external corner tray, so that the external corner (back corner) of the V-shaped body faces downward.

[0045] In an alternative, the assembling device 1002 can only include the assembling table. Workers can use a travelling crane to transport the base plates 2001 to the assembling table and manually perform the above assembling operation.

[0046] The gluing and pasting device is used for gluing and pasting a plurality of V-shaped assemblies at predetermined positions on the V-shaped body. The gluing and pasting device includes a gluing mechanism, a pasting assembly table, and a mechanical arm. The gluing mechanism is used for gluing the workpiece. The pasting assembly table is used for placing the workpiece to be processed. The mechanical arm is used to grab the V-shaped assembly from a specified position and paste it to the glued position on the workpiece.

[0047] In this embodiment, the gluing and pasting device includes a first gluing and pasting device 1003-1, a second gluing and pasting device 1003-2, and a third gluing and pasting device 1003-3. The first gluing and pasting device 1003-1 is used for gluing and pasting a plurality of first V-shaped assemblies 2010 at the inside corners (i.e., the female corners) of the V-shaped body 2000. The second gluing and pasting device 1003-2 is used for gluing and pasting a plurality of second V-shaped assemblies 2011 at the upper ends of the respective first V-shaped assemblies 2010. The third gluing and pasting device 1003-3 is used for gluing and pasting a plurality of back corner assemblies 2012 at the back corners (i.e., the external corners) of the V-shaped body 2000.

[0048] In this embodiment, the glue application mechanism and the adhesive assembly table of each glue application and bonding device are arranged adjacent to each other. In an alternative, multiple glue application mechanisms can be arranged adjacent to each other in sequence, while multiple adhesive assembly tables and glue application mechanisms can be arranged separately in other positions. Alternatively, since the automatic glue application operation is relatively fast, multiple glue application and bonding devices can share a single glue application mechanism.

[0049] The inside corner pressing device is used in conjunction with the outside corner tray to press semi-finished workpieces with inside corners facing upwards, so that the glue between the parts can be cured.

[0050] In this embodiment, the internal corner pressing device includes a first internal corner pressing device 1004-1 and a second internal corner pressing device 1004-2, which are used to press the semi-finished workpiece with the first V-shaped component attached and the semi-finished workpiece with the second V-shaped component attached, respectively.

[0051] Figure 2 This is a structural diagram of the first internal corner pressing device and the external corner tray in this embodiment, which is a side view.

[0052] like Figure 3 As shown, the first internal corner pressing device 1004-1 includes a frame, a lifting mechanism 416, a secondary pressing mechanism 417, and a longitudinal transfer mechanism 830.

[0053] The secondary pressing mechanism 417 includes a pressing bracket 4171 with a V-shaped bottom and two pressing plates 4172 respectively installed on both sides of the bottom of the pressing bracket 4171. The pressing plates 4172 are relatively long and can cover all the multiple first V-shaped components 2010. The included angle between the two pressing plates 4172 corresponds to the included angle of the V-shaped body 2000.

[0054] The corner tray 820 is used to support semi-finished workpieces, keeping them stably with their corners facing downwards. It includes a base 821, an angle adjustment mechanism 822, and two support plates 823. The base 821 is roughly rectangular, and the two support plates 823 are inclinedly mounted on the base 821 via the angle adjustment mechanism 822, forming a V-shape. The included angle between the two support plates 823 is adjustable. The two outer surfaces of the V-shaped body of the semi-finished workpiece contact the upper surfaces of the two support plates 823.

[0055] The structure of the longitudinal transfer mechanism 830 is basically the same as that of the longitudinal transfer mechanism 1013 on the transverse transfer trolley 1012.

[0056] During processing, after the external corner tray 820 and the semi-finished product with the first V-shaped component 2010 attached are transferred to the first internal corner pressing device 1004-1, the lifting mechanism 416 drives the secondary pressing mechanism 417 to press down, and the two pressing plates 4172 respectively press the two upper surfaces of the first V-shaped component 2011.

[0057] Figure 3 This is a structural diagram of the second internal corner pressing device and the external corner tray in this embodiment, which is a side view.

[0058] like Figure 3 As shown, the second internal corner pressing device 1004-2 includes a frame, a lifting mechanism 410, a main layer pressing mechanism 411, a heating plate 412, multiple gas springs 413, a longitudinal transfer mechanism 830, and is used in conjunction with the external corner tray 820.

[0059] The lifting mechanism 410 is mounted on the frame, and the main lamination mechanism 411 is connected to the bottom of the lifting mechanism 410 via multiple gas springs 413. The lifting mechanism 410 is used to drive the corner lamination mechanism 411 to move up and down. The bottom of the lifting mechanism 410 has a horizontal mounting plate, and multiple gas springs 413 are arranged at equal intervals along the length of the mounting plate.

[0060] Heating plate 412 is used to lay on top of the V-shaped assembly to heat it during the pressing process.

[0061] The main lamination mechanism 411 is connected to the lower ends of multiple gas springs 413 and includes multiple pressure heads 414 arranged in two rows along the length of the mounting plate, corresponding to the two ends of the second V-shaped assembly 2011. Each pressure head 414 includes a support rod and a buffer layer covering the lower end of the support rod, and the lower end of the pressure head 414 is hemispherical. The spacing of the pressure heads is such that every four pressure heads 414 correspond to one second V-shaped assembly 2011, and these four pressure heads correspond to the four corners of the second V-shaped assembly 2011.

[0062] The other fixed processing devices below are also equipped with longitudinal transfer mechanisms, which will not be described again.

[0063] During processing, after the semi-finished workpiece with the first V-shaped component 2010 and the second V-shaped component 2011 pasted and cured on the external corner tray 820 is transferred to the second internal corner pressing device 1004-2, the lifting mechanism 410 drives multiple pressing heads 414 to press down, and each of the four pressing heads 414 presses the four corners of the corresponding second V-shaped component 2011.

[0064] The external corner pressing device 1005 is used in conjunction with the internal corner tray to press semi-finished workpieces with attached back corner components.

[0065] Figure 4is a structural diagram of the corner pressing device and the corner supporting tray in this embodiment, which is also a side view.

[0066] As shown in Figure 4 , the corner pressing device 1005 includes a frame, a lifting mechanism 510, a corner pressing mechanism 511, a heating plate 512, and a longitudinal driving mechanism 830. The corner supporting tray 810 used in cooperation is also shown in the figure.

[0067] The lifting mechanism 510 is arranged on the frame, and the corner pressing mechanism 511 is connected to the bottom of the lifting mechanism 510. The lifting mechanism 510 drives the corner pressing mechanism 511 to lift.

[0068] The corner pressing mechanism 511 includes a bent pressing plate 514 matched with the shape of the back corner assembly 2012 and a sheet-shaped air bag 513 arranged at the bottom of the pressing plate. The corner pressing device 1005 further includes a gas charging and discharging pipe connected with the sheet-shaped air bag 513 and a gas charging and discharging driving mechanism (not shown in the figure).

[0069] The heating plate 512 is used to be laid on the back corner assembly and to heat it during the pressing process.

[0070] The corner supporting tray 810 includes a bottom plate 811 and two supporting assemblies 812. The bottom plate 811 is generally in the shape of a long strip plate, and its size is generally the same as that of the bottom plate 821 of the workpiece corner supporting tray 820. The supporting assembly 812 is generally in the shape of a long strip, and is arranged on each side of the width direction of the bottom plate 811. The supporting assembly 812 includes a metal piece connected to the bottom plate 811 and a long strip-shaped wooden supporting strip 8121 installed on the upper end of the metal piece. The upper surfaces of the two supporting strips 8121 are horizontal and generally coplanar, and their spacing corresponds to the spacing of the two ends of the second V-shaped assembly 2011 in the V-shaped assembly. The V-shaped workpiece or semi-finished workpiece can be stably placed on the workpiece corner supporting tray 810 with the corner down, and the two ends of the plurality of second V-shaped assemblies 2011 thereon are in contact with the upper surfaces of the two supporting strips 8121, respectively.

[0071] During processing, after the corner supporting tray 810 and the semi-finished workpiece with the first V-shaped assembly 2010 and the second V-shaped assembly 2011 pasted thereon are transferred to the corner pressing device 1005, the lifting mechanism 510 drives the corner pressing mechanism 511 to press down towards the semi-finished workpiece, and at the same time, the gas charging and discharging mechanism inflates the sheet-shaped air bag 513, so that the inflated sheet-shaped air bag 513 adaptively presses the back corner assembly 2012.

[0072] The turnover device 1007 is used to turn over the semi-finished workpiece as a whole, so that the corner or the corner of the semi-finished workpiece faces upwards, so as to paste and press the assembly on the upward side.

[0073] Figure 6Fig. 2 is a structural diagram of the overturning device and the external corner tray in the embodiment, which is a perspective view.

[0074] As shown in Fig. 2, the overturning device 1007 comprises a rack, a lifting mechanism 710, a pair of overturning mechanisms 711, a pair of clamping mechanisms 712, and a longitudinal driving mechanism 830. Figure 6

[0075] The lifting mechanism 710 is arranged on the rack and is used to drive the overturning mechanisms 711 and the clamping mechanisms 712 to lift.

[0076] Each overturning mechanism 711 comprises a support arm installed at the bottom of the lifting mechanism 710 and extending downward, a rotating driving motor installed on the support arm, and corresponding transmission structure.

[0077] Each clamping mechanism 712 is arranged at the lower end of the corresponding overturning mechanism 711 and comprises a pair of clamping plates 7121 arranged in a V shape to match the V-shaped body 2000, which is used to clamp the end faces of the V-shaped body 2000 of the semi-finished workpiece in the length direction. The overturning mechanism 711 is used to drive the corresponding pair of clamping plates to rotate by 90 degrees, so as to realize the overturning of the semi-finished workpiece.

[0078] Taking the overturning of the semi-finished workpiece from the downward-facing internal corner to the upward-facing external corner as an example, in use, the longitudinal driving mechanism 830 cooperates with the longitudinal driving mechanism 1013 on the transverse trolley 1012 to pick up the external corner tray 820 and the semi-finished workpiece thereon, and then the lifting mechanism 710 drives the overturning mechanisms 711 and the clamping mechanisms 712 to move downward to a position where the pair of clamping mechanisms 712 are respectively located at both sides of the V-shaped body of the semi-finished workpiece in the length direction. Then the clamping mechanisms 712 move towards each other to clamp the semi-finished workpiece. The lifting mechanism 710 drives the overturning mechanisms 711 and the clamping mechanisms 712 to move upward to a safe overturning height, and then the overturning mechanisms 711 drive the pair of clamping mechanisms 712 to rotate synchronously, so as to overturn the semi-finished workpiece with the external corner upward. At the same time of overturning, the transverse trolley 1012 sends an internal corner tray 810 to the position below the semi-finished workpiece. The lifting mechanism 710 drives the clamping mechanisms 712 and the semi-finished workpiece to move downward, and finally the clamping mechanisms 712 release the semi-finished workpiece, so as to realize the overturning of the semi-finished workpiece and place it on the internal corner tray 810.

[0079] The production line further comprises a plurality of packaging devices 1006 and packaging trays, which are used to package the processed V-shaped workpieces. In the embodiment, the plurality of packaging devices 1006 are arranged on one side of the transverse rail 1011 and are close to the overturning device 1007. Each packaging device 1006 comprises a placement table and a mechanical arm. The placement table is used to place the packaging tray and the processed V-shaped workpiece. The mechanical arm is used to pick up the packaging material from a designated position and package the V-shaped workpiece on the placement table. ​

[0080] Figure 5 This is a schematic diagram of the packaging pallet in this embodiment.

[0081] like Figure 5 As shown, the packaging pallet 840 is composed of multiple long strip plates, including a main support plate 841, two foot plates 842, and an upper support plate 843. The three types of plates are of roughly the same length and are arranged parallel to each other, with their ends aligned along their length. The foot plates 842 are narrower than the main support plate 841 and are fixed to the bottom sides of the main support plate 841. The upper support plate 843 is also narrower than the main support plate 841 and is fixed to the top side of the main support plate 841.

[0082] V-shaped workpieces can be placed on a packaging pallet 840, one of which, a base plate 2001, is generally horizontal and its outer end contacts the upper surface of the upper support plate 843. One outer side of the back corner assembly 2012 contacts the upper surface of the main support plate 841, and the other base plate 2001 stands generally vertically or slightly tilted.

[0083] In addition, the production line also includes auxiliary transport devices, such as forklifts, which are used to move packaged V-shaped workpieces and can be used to temporarily replace one of the traverse trolleys 1012 for certain transport operations when one of the traverse trolleys 1012 malfunctions.

[0084] In this embodiment, multiple assembly devices, multiple adhesive application and bonding devices, multiple transition devices, and a flipping device are arranged on one side of the transverse track 1011 (left side of the figure), and multiple inside corner pressing devices and multiple outside corner pressing devices are arranged on the other side of the transverse track 1011 (right side of the figure). Specifically, along one side of the transverse track 1011, three assembly devices 1002, two first adhesive application and bonding devices 1003-1, four first transition devices 1001-1, four second transition devices 1001-2, two second adhesive application and bonding devices 1003-2, one third adhesive application and bonding device 1003-3, and one flipping device 1007 are arranged in sequence. Along the other side of the transverse track 1011, fifteen first inside corner pressing devices 1004-1, twelve second inside corner pressing devices 1004-2, eight outside corner pressing devices 1005, and two third transition devices 1001-3 are arranged in sequence.

[0085] Among the fifteen first inside corner pressing devices 1004-1, four of them are located in the middle part and are continuous, which are used as backup, and can be temporarily used when some of the other eleven second inside corner pressing devices 1004-1 are out of order. Four of the twelve second inside corner pressing devices 1004-2 located on one side and close to the middle part of the horizontal track 1011 are continuous, which are used as backup. Except for the backup fixed processing devices, the number of the rest of the fixed processing devices is set according to the proportion of the operation time of the corresponding process (for example, the assembly time of the assembly device, the pressing time of the pressing device, and the predetermined resting time of the workpiece on the transition device).

[0086] In addition, all the pressing devices are arranged in one or more constant temperature rooms 1020, which have multiple electric control doors corresponding to the number and position of the pressing devices therein. When the electric control doors are opened, the longitudinal transfer mechanism 1013 on the traversing trolley 1012 and the longitudinal transfer mechanism of the pressing device can transfer the tray and the workpiece through the opened electric control door. In this embodiment, all the outside corner pressing devices 1005 are arranged in one constant temperature room 1020, and 3-5 continuous inside corner pressing devices 1004 are arranged in one constant temperature room 1020, and there are seven constant temperature rooms 1020 in total.

[0087] That is, all the pressing devices are arranged on the same side, and the pressing devices, the corresponding glue coating and bonding devices, and the corresponding transition devices are arranged on the same side in the horizontal direction, thereby relatively reducing the travel of each traversing trolley 1012 and reducing the possibility of interference between the two traversing trolleys 1012.

[0088] During production, the two traversing trolleys 1012 can be controlled to move by the operator according to the on-site processing situation, or can be controlled to move by the industrial computer according to the pre-set control process. The corresponding production process is roughly as follows:

[0089] Step S1, the traversing trolley 1012 transports an empty outside corner tray to one of the assembly devices 1002.

[0090] Step S2, at the assembly device 1002, two base plates 2001 and one partition plate are assembled into a V-shaped main body 2000.

[0091] Step S3, the traversing trolley 1012 takes the V-shaped main body 2000 from the assembly device 1002 and transports it to one of the first glue coating and bonding devices 1003-1.

[0092] Step S4, at the first glue coating and bonding device 1003-1, a plurality of first V-shaped components 2010 are glued and bonded at the inside corners of the V-shaped main body 2000 to form a first semi-finished workpiece.

[0093] Step S5, the horizontal transfer trolley 1012 picks up the first semi-finished product from the first glue coating and pasting device 1003-1 and transports it to one of the first inside corner pressing devices 1004-1.

[0094] Step S6, the first inside corner pressing device 1004-1 presses the first semi-finished product.

[0095] Step S7, after pressing, the horizontal transfer trolley 1012 picks up the outside corner tray and the pressed first semi-finished product from the first inside corner pressing device 1004-1 and transports them to the first transition device 1001-1 for standing.

[0096] Step S8, after standing, the horizontal transfer trolley 1012 picks up the outside corner tray and the first semi-finished product from the first transition device 1001-1 and transports them to one of the second glue coating and pasting devices 1003-2.

[0097] Step S9, at the second glue coating and pasting device 1003-2, a second V-shaped component 2011 is coated with glue and pasted on each first V-shaped component 2010 to form a second semi-finished product.

[0098] Step S10, the horizontal transfer trolley 1012 picks up the second semi-finished product from the second glue coating and pasting device 1003-2 and transports it to one of the second inside corner pressing devices 1004-2.

[0099] Step S11, the second inside corner pressing device 1004-2 presses the second semi-finished product.

[0100] Step S12, the horizontal transfer trolley 1012 picks up the outside corner tray and the second semi-finished product from the second inside corner pressing device 1004-2 and transports them to the turnover device 1007.

[0101] Step S13, the turnover device 1007 turns over the second semi-finished product with its outside corner facing up, and cooperates with the horizontal transfer trolley 1012 to replace the outside corner tray at the turnover device 1007 with an inside corner tray, and then places the turned over second semi-finished product on the inside corner tray.

[0102] Step S14, the horizontal transfer trolley 1012 picks up the inside corner tray and the second semi-finished product from the turnover device 1007 and transports them to one of the third glue coating and pasting devices 1003-3.

[0103] Step S15, at the third glue coating and pasting device 1003-3, a plurality of back corner components 2012 are coated with glue and pasted on the outside corner of the V-shaped body 2000 to form a third semi-finished product.

[0104] Step S16, the horizontal transfer trolley 1012 takes the female corner tray and the third semi-finished product workpiece from the third gluing and bonding device 1003-3 and transports them to one of the male corner pressing devices 1005.

[0105] Step S17, the male corner pressing device 1005 presses the third semi-finished product workpiece to form a V-shaped workpiece.

[0106] Step S18, the horizontal transfer trolley 1012 takes the female corner tray and the V-shaped workpiece from the male corner pressing device 1005 and transports them to the turnover device 1007.

[0107] Step S19, the turnover device 1007 turns over the V-shaped workpiece so that one edge is substantially horizontal, and at the same time, in cooperation with the horizontal transfer trolley 1012, replaces the female corner tray at the turnover device 1007 with a packaging tray, and then places the turned-over V-shaped workpiece on the packaging tray.

[0108] Step S20, the horizontal transfer trolley 1012 takes the packaging tray and the V-shaped workpiece from the turnover device 1007 and transports them to one of the packaging devices 1006.

[0109] Step S21, the V-shaped workpiece is packaged at the packaging device 1006.

[0110] Effects of the embodiment one

[0111] The multi-layered V-shaped workpiece batch bonding and assembling production line provided by the embodiment includes a horizontal track, a horizontal transfer trolley arranged on the horizontal track, a plurality of fixed processing devices arranged along the two sides of the horizontal track, a male corner tray and a female corner tray for supporting semi-finished product workpieces in different postures. Since the horizontal transfer trolley and the plurality of fixed processing devices both have longitudinal transfer mechanisms, when the horizontal transfer trolley moves horizontally to each fixed processing device, the two longitudinal transfer mechanisms can be docked to transfer the tray and the workpiece. The tray can keep the workpiece stable during the transfer process, so the workpiece can be conveniently and quickly transferred between the plurality of fixed processing devices of different processes, thereby saving a large amount of manpower and time consumed by manual handling of heavy V-shaped workpieces and their semi-finished products, and avoiding damage to the V-shaped workpieces and their semi-finished products during manual handling, thereby improving the yield.

[0112] In the embodiment, two horizontal moving trolleys are arranged on the horizontal track, and multiple fixed processing devices are arranged in sequence along the horizontal direction according to the sequence of corresponding processes, and each type of pressing device is arranged corresponding to the transition device and the glue coating and bonding device in the vertical direction, so that the total travel of the two horizontal moving trolleys can be relatively minimized in the whole production process of a workpiece, and the two horizontal moving trolleys are less likely to interfere with each other, and one trolley is less likely to wait, so that the conveying capacity of the horizontal moving trolleys and the equipment time of each fixed processing device can be fully utilized, and the production efficiency is improved.

[0113] Further, the longitudinal transfer mechanisms are chain type driving devices, which are mature and reliable in related technology, and when transferring the semi-finished workpieces, the two longitudinal transfer mechanisms do not need to be high-precision docked, only need to be relatively close at the ends, and the spacing is at least less than half the length of the tray bottom, so that the tray and the workpiece can be stably transferred, and the transfer speed is relatively fast, which is significantly faster than manual carrying.

[0114] Further, the male corner tray has two support plates arranged in a V shape, so that the V-shaped workpiece or semi-finished workpiece with the male corner downward can be stably supported; the female corner tray has two wooden support bars, so that the V-shaped workpiece or semi-finished workpiece can be supported by the two ends of the multiple second V-shaped components on the V-shaped workpiece or semi-finished workpiece, and the V-shaped workpiece or semi-finished workpiece with the female corner downward can be stably supported, and the second V-shaped component is a metal piece, so that it can play a certain buffering role in the transfer process through the relatively softer support bar. Therefore, through the two types of trays, horizontal moving trolleys and longitudinal transfer mechanisms, the workpieces can be stably transferred between the fixed processing devices.

[0115] Further, multiple pressing devices are arranged in the constant temperature room, and the constant temperature room has multiple electric control doors matched therewith, so that the semi-finished workpieces can be pressed under more suitable temperature conditions, the pressing effect is better, and through the cooperation of the electric control doors with the horizontal moving trolleys and the longitudinal transfer mechanisms, the transfer of the trays and the workpieces is not affected.

[0116] <Embodiment Two>

[0117] The embodiment provides a batch bonding and assembling production line for multi-layer superimposed V-shaped workpieces, and in the embodiment, the same reference signs are given to the same constituent elements as in Embodiment One, and the corresponding description is omitted.

[0118] In Embodiment One, there is only one horizontal track 1011, and two horizontal moving trolleys 1012 are arranged on the track. In a few cases, one trolley is still blocked by the other trolley and has to wait temporarily, and the utilization of equipment time is still not fully sufficient. The production line of the embodiment aims to further solve this problem.

[0119] Compared with the embodiment one, the difference is that there are multiple lateral transfer devices in the multi-layered V-shaped workpiece batch bonding assembly production line, and the layout of the fixed processing devices is correspondingly different.

[0120] Figure 7 is the layout schematic diagram of the multi-layered V-shaped workpiece batch bonding assembly production line in this embodiment.

[0121] As shown in Figure 7 , the production line of this embodiment includes four lateral transfer devices 1010, each lateral transfer device 1010 includes a lateral track 1011 extending in the lateral direction and a lateral transfer trolley 1012. Multiple fixed processing devices are arranged on both sides of the four lateral tracks 1011, that is, part of the fixed processing devices are located between adjacent two tracks.

[0122] Specifically, the first lateral track 1011-1 to the fourth lateral track 1011-4 are arranged in order from right to left in the figure. Among them, the length of the first lateral track 1011-1 is less than that of the other lateral tracks.

[0123] Three first glue coating and pasting devices 1003-1 and three assembly devices 1002 are arranged in order on one side (the upper side in the figure) of the first lateral track 1011-1. Each glue coating and pasting device includes a glue coating mechanism, a pasting assembly table and a mechanical arm. Since the glue coating is relatively fast, in an alternative, the three glue coating and pasting devices can also share one glue coating mechanism.

[0124] Four rows of fixed processing devices are arranged in the lateral direction between the first lateral track 1011-1 and the second lateral track 1011-2. Eight first inside corner pressing devices 1004-1 are arranged in order on the other side (the lower side in the figure) of the first lateral track 1011-1, and the remaining three rows each include eight first transition devices 1001-1. In the longitudinal direction, each first inside corner pressing device 1004-1 is aligned with three first transition devices 1001-1, and the four fixed processing devices in this column are arranged adjacent to each other in the longitudinal direction. The four fixed processing devices in this column can transfer the tray and the workpiece in the direction of the arrow in the figure through the longitudinal transfer mechanism thereof. Eight first transition devices 1001-1 and two second glue coating and pasting devices 1003-2 are arranged in order on one side of the second lateral track 1011-2.

[0125] Four rows of fixing treatment devices are arranged in the lateral direction between the second lateral track 1011-2 and the third lateral track 1011-3. The other side of the second lateral track 1011-2 is sequentially provided with seven second inside corner pressing devices 1004-2, and the remaining three rows each include eight second transition devices 1001-2. In the longitudinal direction, each second inside corner pressing device 1004-2 is aligned with three second transition devices 1001-2, and the four fixing treatment devices in the column are arranged adjacent to each other, and the tray and the workpiece can be transferred in the direction of the arrow in the drawing by the longitudinal transfer mechanism.

[0126] Five outside corner pressing devices 1005 and three third transition devices 1001-3 are sequentially arranged in the lateral direction between the third lateral track 1011-3 and the fourth lateral track 1011-4.

[0127] Two third transition devices 1001-3, one turnover device 1007, and two third glue coating and pasting devices 1003-3 are sequentially arranged on the other side of the fourth lateral track 1011-4. A plurality of packaging devices 1006 are arranged on the other side of the third glue coating and pasting device 1003-3. In addition, a space is reserved between the turnover device 1007 and one third glue coating and pasting device 1003-3 for the passage and operation of auxiliary conveying devices (such as forklifts).

[0128] In this embodiment, other structures are the same as those in Embodiment One, and thus will not be repeated.

[0129] The corresponding production and processing flow is also substantially the same as that shown in Embodiment One, except that after the completion of pressing by each inside corner pressing device, the tray and the workpiece are directly transferred to the corresponding plurality of transition devices by the longitudinal transfer mechanism for the static placement of the workpiece, and the tray and the workpiece are transferred between different fixing treatment devices by the corresponding lateral transfer trolley.

[0130] Effects of Embodiment Two

[0131] According to the multi-layered V-shaped workpiece batch bonding and assembling production line provided in this embodiment, on the basis of the effects of Embodiment One, since a plurality of lateral tracks parallel to each other and a plurality of lateral transfer trolleys are arranged, the plurality of lateral transfer trolleys can be used to transfer the tray and the workpiece between different fixing treatment devices in different processes. Since there is only one lateral transfer trolley on each track, the plurality of lateral transfer trolleys will not interfere with each other. In this way, a larger number of fixing treatment devices can be arranged on both sides of the plurality of lateral tracks and between every two adjacent lateral tracks, and the plurality of lateral transfer trolleys can meet the workpiece transfer requirements when a plurality of production lines produce a plurality of workpieces at the same time, thereby realizing larger-scale production. In addition, the production line of this embodiment can also be used in a space with limited length (the length is not enough to arrange the scheme of Embodiment One).

[0132] Further, a plurality of fixing treatment devices are arranged between the lateral tracks, and the fixing treatment devices are respectively aligned in the longitudinal direction to form a plurality of columns, and the fixing treatment devices in each column can directly transfer the tray and the workpiece in the longitudinal direction through the longitudinal transfer device, so as to reduce the burden of the lateral transfer trolley, and for a large number of fixing treatment devices, a relatively small number of lateral transfer trolleys can be arranged, that is, a larger number of fixing treatment devices can be arranged in a limited space, and the production capacity is improved.

[0133] Further, each column of fixing treatment devices is a pressing device and a plurality of corresponding transition devices, and the number ratio of each type of pressing device and its corresponding transition device is set according to the time ratio of its pressing time and corresponding static time, so that the number of devices is reasonable, and the idle waiting of a certain type of pressing device or transition device can be avoided, the time of each device is fully utilized, and the production efficiency is further improved.

[0134] <Embodiment Three>

[0135] The embodiment provides a multi-layer stacked V-shaped workpiece batch bonding assembly production line, and in the embodiment, the same components as those in embodiment two are assigned the same symbols and the corresponding descriptions are omitted.

[0136] In the production line of embodiment two, the production efficiency is greatly improved by arranging a plurality of lateral tracks and reasonably arranging fixing treatment devices beside the tracks and between the two tracks. However, the production line still has a small problem. In mass production, a large number of trays will accumulate on the transition device near the turnover device, so manual operation is required to regularly transfer the trays from the transition device on one side to the transition device on the other side by using other handling equipment, which requires a larger passing space beside the entire production line and is inconvenient to operate. The production line of the embodiment aims to further solve this problem.

[0137] Figure 8 is a layout schematic diagram of the multi-layer stacked V-shaped workpiece batch bonding assembly production line in the embodiment.

[0138] As shown in Figure 8 Compared with embodiment two, the production line of the embodiment further has nine return devices, and the structure of the return device is consistent with that of the transition device.

[0139] Four of them are first return devices 1009-1, arranged between the first lateral track 1011-1 and the second lateral track 1011-2, and sequentially arranged along the longitudinal direction, with the two ends respectively arranged on the other side of the first lateral track 1011-1 and on one side of the second lateral track 1011-2, so as to take the tray from the second transverse trolley 1012-2 and transport the tray to the first transverse trolley 1012-1 along the longitudinal direction, thereby realizing the backflow of the empty tray. Another four are second return devices 1009-2, arranged between the second lateral track 1011-2 and the third lateral track 1011-3, and sequentially arranged along the longitudinal direction, with the two ends respectively arranged on the other side of the second lateral track 1011-2 and on one side of the third lateral track 1011-3, so as to realize the backflow of the empty tray. There is also a third return device 1009-3 arranged between the third lateral track 1011-3 and the fourth lateral track 1011-4.

[0140] In the lateral direction, a column of return devices 1009 is arranged between a plurality of pressing devices and corresponding transition devices. In this embodiment, one column of first return devices 1009-1 has six columns of first female corner pressing devices 1004-1 and corresponding transition devices on one side, and two columns of first female corner pressing devices 1004-1 and corresponding transition devices on the other side; one column of second return devices 1009-2 has five columns of second female corner pressing devices 1004-2 and corresponding transition devices on one side, and two columns of second female corner pressing devices 1004-2 and corresponding transition devices on the other side, and the predetermined conveying direction of the column of return devices 1009 is opposite to the predetermined conveying direction of the plurality of pressing devices on both sides and the corresponding transition devices. The third return device 1009-3 has a plurality of male corner pressing devices 1005 on one side and a plurality of corresponding transition devices on the other side.

[0141] In this embodiment, other structures are the same as in Embodiment Two, and therefore will not be repeated.

[0142] Effects of Embodiment Three

[0143] According to the multi-layer V-shaped workpiece batch bonding and assembling production line provided in this embodiment, on the basis of the effects of Embodiment Two, since there are also two columns of return devices, the empty tray can also be sent back to the vicinity of the fixed treatment device at the earlier stage of the process through the return device, without the need to send the empty tray back through other conveying devices such as forklifts and AGV trolleys, so that the production efficiency is higher, and the production line does not need to reserve additional conveying space around it, so that more fixed treatment devices can be arranged in a limited space.

[0144] The above examples are only used for illustrating the specific implementation manners of the present application, and the present application is not limited to the description range of the above examples. It should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and the description in the specification are only used for illustrating the principle of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application.
