[0002] In the production process of lithium batteries, since the lithium batteries on the pallets require multiple processing steps, it is often necessary to change the pallets on conveyor line one to conveyor line two that is perpendicular to conveyor line one for further processing. Manual line changing is time-consuming and labor-intensive. Therefore, line changing work is often completed through line changing devices.

[0003] At present, the line changing device between the vertical conveyor line 1 and the conveyor line 2 with different heights includes a driving mechanism, a conveyor belt, a cylinder, a base frame and a turntable. The push end of the cylinder is connected to the turntable, the driving mechanism is installed on one side of the turntable, and the conveyor belt is installed on the driving mechanism. The conveyor belt is driven to move by the driving mechanism. The turntable is used to drive the pallet to rotate. After the pallet on the higher conveyor line 1 is transported to the conveyor belt, the turntable rotates and the cylinder drives the turntable to descend, so that the pallet can be transported to the lower conveyor line 2. After the pallet is completely moved out of the conveyor belt, the turntable is reset, the cylinder is reset, and the line change for the next pallet is carried out.

[0049] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] Embodiment 1:

[0051] like Figure 1-Figure 6 As shown, an embodiment of the present invention provides a line changing device for changing the pallets on two vertically arranged conveyor lines 1 and 2, the line changing device comprising a mounting frame 1, a second conveyor mechanism 2, a first conveyor mechanism, a first baffle 3 and a support mechanism 5;

[0052] The second conveying mechanism 2 and the first conveying mechanism are both installed on the mounting frame 1, and the conveying direction of the second conveying mechanism 2 is perpendicular to the conveying direction of the first conveying mechanism;

[0053] The first conveying mechanism includes a conveyor belt 4, the conveyor belt 4 has a bearing surface for bearing objects, and a support mechanism 5 is installed on the bearing surface of the conveyor belt 4 for bearing the pallet, and the length of the support mechanism 5 is not greater than half of the total length of the conveyor belt 4;

[0054] The bearing surface of the supporting mechanism 5 is higher than the bearing surface of the second conveying mechanism 2, and the bearing surface of the second conveying mechanism 2 is higher than the bearing surface of the conveyor belt 4;

[0055] The first baffle 3 is arranged along the conveying direction of the second conveying mechanism 2 and is higher than the second conveying mechanism 2. When the pallet follows the supporting mechanism 5 to move to the first extreme position along the conveying direction of the conveyor belt 4, the first baffle 3 is used to limit the pallet from continuing to move along the conveying direction of the conveyor belt 4.

[0056] Specifically, the pallet on conveyor line 1 is transported to the support mechanism 5 installed on the bearing surface of the conveyor belt 4 for transportation until one side of the pallet is supported by the first baffle plate 3. At this time, the conveyor belt 4 continues to move, and the first baffle plate 3 limits the movement of the pallet along the conveying direction of the conveyor belt 4, forcing the pallet on the support structure to gradually separate from the support mechanism 5. When the pallet leaves the support mechanism 5, since the bearing surface of the second conveyor mechanism 2 is lower than the bearing surface of the support mechanism 5, the pallet falls on the bearing surface of the second conveyor mechanism 2. The pallet is driven by the second conveyor mechanism 2 to move to conveyor line 2, and the line changing operation can be completed. The entire work process does not require lifting and rotation, and since the length of the support mechanism 5 is not greater than half of the total length of the conveyor belt 4, there is enough area on the conveyor belt 4 to allow the lower surface of the pallet to rest on the bearing surface of the second conveyor mechanism 2. There is no rotation and lifting operation process in the entire line changing process, which greatly reduces the work steps and improves work efficiency.

[0057] Preferably, the length of the support mechanism 5 is equal to half of the total length of the conveyor belt 4. Optionally, the total length of the support mechanism 5 is less than half of the total length of the conveyor belt 4. For the convenience of description, the area on the bearing surface of the conveyor belt 4 where the support mechanism 5 is installed is recorded as the installation section, and the remaining area is recorded as the unloaded section. The length of the unloaded section must be greater than the length of the pallet, and the length direction of the pallet is the same as the conveying direction of the conveyor belt 4. The length of the installation section is the same as the length of the support mechanism 5, and the length of the installation section is greater than half of the length of the pallet, ensuring that the pallet will not fall from the support mechanism 5 due to the center of gravity shift before it contacts the first baffle 3.

[0058] It should be noted that the first extreme position refers to the position where the tray and the first baffle plate 3 are aligned with each other, and the first baffle plate 3 and the mounting frame 1 are fixedly connected.

[0059] According to one embodiment of the present invention, the support mechanism 5 includes a plurality of support components, and the plurality of support components are sequentially installed on the bearing surface of the conveyor belt 4 along the conveying direction of the conveyor belt 4 .

[0060] Preferably, a gap is left between each two adjacent groups of support components, and they are not connected to each other, and each group of support components is fixedly connected to the conveyor belt 4.

[0061] Optionally, two adjacent groups of support components can be hinged, and the hinge is set close to the conveyor belt 4 so that it will not affect the normal operation of the conveyor belt 4. By hingedly connecting the two adjacent groups of support components, even if the connection between one group of support components and the conveyor belt 4 becomes loose, it can be limited by the adjacent support components on both sides, and the overall stability is higher.

[0062] Of course, in this embodiment, the support mechanism 5 can also be in other forms, for example, the support mechanism 5 is a conveyor belt, the thickness of the conveyor belt is greater than the thickness of the conveyor belt 4, and the conveyor belt is fixedly connected to the installation section of the conveyor belt 4. Its purpose does not deviate from the design concept of the present invention, and therefore, it should belong to the protection scope of the present invention.

[0063] According to one embodiment of the present invention, Figure 2 As shown, two conveyor belts 4 are provided, and the two conveyor belts 4 are symmetrically arranged on both sides of the second conveying mechanism 2 .

[0064] Two conveyor belts 4 are provided, and the two conveyor belts 4 are respectively located on both sides of the pallet, which can provide a more stable supporting and transporting effect.

[0065] Of course, in this embodiment, the second conveying mechanism 2 can be provided with multiple groups, and a conveyor belt 4 is provided between each two adjacent second conveying mechanisms 2, and the pallet can also slide from the multiple groups of supporting components on the conveyor belt 4 to the bearing surface of the second conveying mechanism 2. Its purpose does not deviate from the design concept of the present invention, and therefore, it should belong to the protection scope of the present invention.

[0066] According to one embodiment of the present invention, Figure 2 As shown, a second driving assembly 7 and a second baffle 8 are provided on a side of the mounting frame 1 away from the first baffle 3. The second baffle 8 is mounted on the second driving assembly 7. The second driving assembly 7 is used to drive the second baffle 8 to move.

[0067] The first baffle plate 3 and the second baffle plate 8 cooperate to guide the tray to move along the conveying direction of the second conveying mechanism 2 .

[0068] The first baffle plate 3 and the second baffle plate 8 are both located between the two conveyor belts 4. The length direction of the first baffle plate 3 is the same as the length direction of the second baffle plate 8.

[0069] By providing the second baffle 8 and the second drive assembly 7, the second baffle 8 can descend without interfering with the movement of the pallet during the process of transporting the pallet by the conveyor belt 4. When one side of the pallet is supported by the first baffle 3, the second drive assembly 7 drives the second baffle 8 to rise and move horizontally at the same time, so that the second baffle 8 can abut against the side wall of the pallet away from the first baffle 3, and cooperate with the first baffle 3 to guide the pallet to move only along the conveying direction of the second conveying mechanism 2, so that it has higher stability during transportation and more accurate transportation direction.

[0070] According to one embodiment of the present invention, Figure 5 As shown, the support assembly includes a base 501, a first circular shaft 502, a roller 503 and a cover 504;

[0071] The base 501 is fixedly connected to the conveyor belt 4 by a first bolt, and a mounting seat 505 is fixedly connected to the top of the base 501. The mounting seat 505 is provided with a receiving groove, and a first circular shaft 502 is installed in the receiving groove. The first circular shaft 502 is sleeved with a roller 503. The cover body 504 is connected to the top of the base 501, and a making way hole for making way for the roller 503 is provided on the cover body 504.

[0072] The supporting assembly is compact as a whole and can be easily arranged on the conveyor belt 4 .

[0073] There are multiple ways to connect the first circular shaft 502 and the roller 503 , all of which can reduce the friction between the tray and the roller 503 when the tray slides on the roller 503 .

[0074] Preferably, the first circular shaft 502 is interference fit with the receiving groove, two ends of the first circular shaft 502 are clamped by two opposite side walls of the receiving groove, and the roller 503 is rotatably connected to the first circular shaft 502 .

[0075] Optionally, the first circular shaft 502 is placed in the receiving groove, and the roller 503 is interference fit with the first circular shaft 502. The roller 503 is limited by using the clearance hole. At this time, sliding friction is generated in the contact area between the first circular shaft 502 and the receiving groove, and the first circular shaft 502 and the roller 503 rotate as a whole, which can also reduce the friction between the tray and the roller 503.

[0076] Specifically, first limiting blocks are provided on both sides of the mounting seat 505, and a first limiting groove is provided on the base 501. The first limiting blocks are inserted into the first limiting groove to position the mounting seat 505 on the base 501. Similarly, second limiting grooves are symmetrically provided on the top of the mounting seat 505, and second limiting blocks are symmetrically provided on both sides of the cover 504. The second limiting blocks are inserted into the second limiting grooves to achieve positioning of the cover 504 and the mounting seat 505, thereby making the positions of the cover 504 and the mounting seat 505 more accurate, and the position of the roller 503 is not easily offset, and the stability during transportation is higher. Of course, the first limiting groove and the first limiting block can be fixed by interference fit, or can be fixed by gluing, screwing, etc.

[0077] After the pallet completely enters the conveyor line 2 (for example Figure 8 As shown, the line changing device is located between the first conveying section and the second conveying section of conveyor line 2). When the pallet moves to the first extreme position, the first baffle 3 abuts against the pallet to limit the movement of the pallet. At this time, the multiple groups of support components at the bottom of the pallet continue to move along the movement direction of the conveyor belt 4, and friction is generated between the pallet and the support components. In order to reduce the friction, the first circular shaft 502 and the roller 503 are set so that when the pallet and the support component move relative to each other, the friction is reduced due to the rolling of the roller 503, thereby reducing the wear length of the pallet and the support component and extending its service life.

[0078] Furthermore, a first stopper 506 is fixedly connected to the mounting seat 505, and the cooperation of the multiple first stoppers 506 on the two conveyor belts 4 can guide the pallet to move only along the conveying direction of the conveyor belts 4, so that the moving direction will not be offset.

[0079] A second stopper is provided at one end of each supporting mechanism 5 , and the second stopper can limit the tray from sliding out from the front end of the supporting mechanism 5 , thereby preventing the tray from sliding off from the front end of the supporting mechanism 5 and causing a chuck.

[0080] It should be noted that when the support mechanism 5 is at the initial position, its head end is located on the side close to the second baffle 8, and as the conveyor belt 4 is conveyed, its head end gradually moves away from the second baffle 8 toward the first baffle 3. The direction from the tail end to the head end of the support mechanism 5 is the same as the conveying direction of the conveyor belt 4.

[0081] During actual transportation, the effective linear speed of the conveyor belt 4 is slightly greater than the linear speed of the conveyor line 1, and the setting of the roller 503 on the conveyor belt 4 eliminates the speed difference and relative friction.

[0082] According to one embodiment of the present invention, the mounting frame 1 is a rectangular frame, and the rectangular frame includes two parallel side plates 101 and two parallel connecting rods 102;

[0083] The length direction of the connecting rod 102 is perpendicular to the length direction of the side plate 101, and the length direction of the connecting rod 102 is perpendicular to the length direction of the conveyor belt 4;

[0084] A support plate 9 is fixedly connected to one side of the two side plates 101 that are close to each other. The support plate 9 corresponds to the conveyor belt 4 one by one, and the support plate 9 is used to support the conveyor belt 4.

[0085] The setting of the support plate 9 can prevent the middle part of the conveyor belt 4 from sagging during long-term transportation because it is supported by the support plate 9, which can improve its transportation stability. The support plate 9 is made of wear-resistant material and is anisotropic with the conveyor belt 4, which reduces the possibility of biting and adhesion, and further improves the transportation stability.

[0086] According to one embodiment of the present invention, Figure 4 As shown, the first conveying mechanism includes a first driving assembly 6, and the first driving assembly 6 includes a first motor 601, a first pulley 602, a second pulley 603, a connecting shaft 605 and a pulley assembly;

[0087] There are two groups of pulley assemblies, and the pulley assemblies correspond to the conveyor belt 4 one by one. The pulley assemblies include a third pulley 606 and a fourth pulley 607. The two third pulleys 606 are fixedly connected to the two ends of the connecting shaft 605 respectively;

[0088] The fixed end of the first motor 601 is connected to the mounting frame 1, and the output end of the first motor 601 is fixedly connected to the first pulley 602, and the first pulley 602 is transmission-connected to the second pulley 603 through a transmission belt 604, and the third pulley 606 and the second pulley 603 are fixedly connected through a connecting shaft 605, and both ends of the connecting shaft 605 are rotationally connected to the two side plates 101 respectively;

[0089] The axis of the second pulley 603, the axis of the third pulley 606 and the axis of the connecting shaft 605 coincide with each other;

[0090] The third pulley 606 and the fourth pulley 607 are both rotatably connected to the side plate 101 , and the third pulley 606 and the fourth pulley 607 are transmission-connected via the conveyor belt 4 .

[0091] The first motor 601 rotates, driving the first pulley 602 to rotate, and then driving the second pulley 603 to rotate through the transmission belt 604. The second pulley 603 can drive the connecting shaft 605 to rotate and the third pulley 606 to rotate synchronously, so that the conveyor belt 4 drives the pallet to move.

[0092] Furthermore, in order to improve the degree of synchronization of the synchronous operation of the two conveyor belts 4, a fourth circular shaft is fixedly connected between the two fourth pulleys 607, so that the two fourth pulleys 607 can ensure synchronous rotation.

[0093] According to one embodiment of the present invention, the second conveying mechanism 2 includes a third driving assembly and two sets of roller assemblies;

[0094] Two sets of roller assemblies are respectively mounted on two connecting rods 102;

[0095] The roller assembly includes a plurality of mounting blocks 202, which are arranged in sequence along the length direction of the connecting rod 102, and the mounting blocks 202 are fixedly connected to the connecting rod 102;

[0096] Each mounting block 202 is rotatably connected to a second circular shaft, and each second circular shaft is fixedly connected to a roller 201;

[0097] The bearing surface of the roller 201 is higher than the upper surface of the mounting block 202;

[0098] The third driving assembly is used to drive the multiple rollers 201 to rotate around their respective axes, and the multiple rollers 201 cooperate to drive the tray to move.

[0099] Further, such as Figure 6 As shown, a T-shaped long slot is provided on the connecting rod 102, and the length of the T-shaped long slot is equal to the length of the connecting rod 102. A T-shaped block is provided at the bottom of the mounting block 202, and the T-shaped block is slidably connected in the T-shaped long slot. A first through hole is provided on the mounting block 202, and a first screw hole is provided on the T-shaped block. The second bolt passes through the first screw hole and is screwed to the first screw hole. Since the T-shaped block slides in the T-shaped long slot, when the second bolt is screwed, the T-shaped block can move close to the mounting block 202, and then the top wall of the T-shaped long slot is clamped between the T-shaped block and the mounting block 202, thereby realizing the fixed installation of the mounting block 202. This installation method is also convenient for removing the roller 201 for replacement and maintenance.

[0100] The roller 201 and the second circular shaft are both made of plastic and are fixed by interference fit.

[0101] The third driving assembly can drive the multiple rollers 201 in the two roller assemblies to rotate synchronously. The axes of the multiple rollers 201 are parallel, and the axis direction of the rollers 201 is the same as the length direction of the conveyor belt 4;

[0102] The bearing surfaces of the multiple rollers 201 are located in the plane, and the bearing surfaces of the rollers 201 are higher than the transport end surface of the conveyor belt 4 (i.e. the bearing surface of the conveyor belt 4) by 1-2 mm, preferably by 1.5 mm, and the bearing surface of the roller 503 in the support assembly is higher than the bearing surface of the rollers 201 by 1-2 mm, preferably by 1.5 mm. This allows the pallet to achieve a smooth transition switch from conveyor line 1 to conveyor line 2.

[0103] Preferably, the third drive assembly includes a second motor, a first sprocket and a second sprocket, the first sprocket and the second sprocket are connected by a chain transmission, the first sprocket is fixedly connected to one of the rollers 201, and the axis of the first sprocket coincides with the axis of the roller 201. In order not to interfere with the roller 201 in transporting the pallet, the diameter of the first sprocket is smaller than the diameter of the roller 201, and thus the bearing surface of the first sprocket is lower than the bearing surface of the roller 201.

[0104] Optionally, the third driving component is a built-in micro motor, and each mounting block 202 is mounted with a micro motor, which drives the corresponding roller 201 to rotate, and the micro motor is set to be synchronous and of the same speed, and turned on and off at the same time.

[0105] According to one embodiment of the present invention, the second driving assembly 7 includes a first connecting rod 701, a second connecting rod 702, a top plate 703, a bottom plate 705 and a cylinder 704;

[0106] The second baffle 8 is installed on one side of the top plate 703;

[0107] Along the length direction of the conveyor belt 4, the first connecting rod 701 and the second connecting rod 702 are sequentially arranged, and one end of the first connecting rod 701 and one end of the second connecting rod 702 are both rotatably connected to the top plate 703, and the other end of the first connecting rod 701 and the other end of the second connecting rod 702 are both rotatably connected to the bottom plate 705, and the bottom plate 705 is fixedly connected to the mounting frame 1;

[0108] The fixed end of the cylinder 704 is fixedly connected to the mounting frame 1, the pushing end of the cylinder 704 is fixedly connected to a concave block, the concave block is fixedly connected to a third circular shaft, a first axial hole is opened on the first connecting rod 701, and the third circular shaft is rotatably connected in the first axial hole.

[0109] In the initial position, the first connecting rod 701, the second connecting rod 702, the top plate 703 and the bottom plate 705 form a first parallelogram. At this time, the angle between the second connecting rod 702 and the bottom plate 705 in the first parallelogram is denoted as α. Since the two ends of the first connecting rod 701 are rotatably connected to the top plate 703 and the bottom plate 705 respectively, and the two ends of the second connecting rod 702 are rotatably connected to the top plate 703 and the bottom plate 705 respectively, the shape of the first parallelogram is changed when the cylinder 704 pushes When the first connecting rod 701 is moved, the angle between the first connecting rod 701 and the bottom plate 705 changes until the second baffle 8 moves into place and the cylinder 704 stops. The first parallelogram is deformed to form a second parallelogram. At this time, the angle between the second connecting rod 702 and the bottom plate 705 in the second parallelogram is recorded as β. The degree of α is closer to 90 degrees than the degree of β. During the pushing process of the cylinder 704, the top plate 703 moves toward the first baffle 3 and upward at the same time.

[0110] Of course, in this embodiment, the second drive assembly 7 can also be in other forms, for example, the second drive assembly 7 includes an electric push rod, the fixed end of the electric push rod is fixedly connected to the mounting frame 1, and the pushing end of the electric push rod is fixedly connected to the bottom of the second baffle 8. At this time, it should be noted that at this time, the distance between the first baffle 3 and the second baffle 8 cannot be adjusted. Therefore, when designing, the electric push rod needs to be placed according to the actual size of the tray. Its purpose does not deviate from the design concept of the present invention, and therefore, it should belong to the protection scope of the present invention.

[0111] Specifically, a first stopper is provided at one end of conveyor line 1 close to conveyor line 2. Setting a stopper on the conveyor line to stop the pallet at a designated position for waiting is a prior art, and its working principle is not described in detail. When the pallet on conveyor line 1 is located at one end close to conveyor line 2, the first stopper is opened to stop the pallet. According to the working state of the first drive assembly 6, there are generally two situations:

[0112] Case 1: The first drive assembly 6 is always in working condition. When the head end of the support mechanism 5 moves to the specified position after debugging (the head end of the support mechanism 5 is above the conveyor belt 4), the first stopper releases the pallet, and the first drive assembly 6 always drives the conveyor belt 4 to move, so that the pallet on conveyor line 1 moves to the support mechanism 5.

[0113] Case 2: The first drive assembly 6 works intermittently. In the initial position, the support mechanism 5 is completely located above the conveyor belt 4. When the pallet has not completely entered the support mechanism 5, the support mechanism 5 is in a stopped state, and the first stopper releases the pallet. When the pallet is completely transported to the support mechanism 5, the first drive assembly 6 starts to work, driving the conveyor belt 4 to move, thereby causing the support mechanism 5 and the pallet to move synchronously.

[0114] In either case, when the pallet moves to the first extreme position (the first baffle 3 abuts against the pallet), the first baffle 3 limits the pallet from continuing to move along the conveying direction of the conveyor belt 4, and the pallet gradually separates from the bearing surface of the support mechanism 5. At this time, the second baffle 8 rises and translates under the drive of the second drive assembly 7. When the pallet completely separates from the bearing surface of the support mechanism 5, it falls onto the bearing surfaces of multiple rollers 201 on the second conveying mechanism 2. At this time, the pallet is limited between the first baffle 3 and the second baffle 8, so that the pallet is driven by the second conveying mechanism 2 to move along the conveying direction of the second conveying mechanism 2, and then the pallet is conveyed to conveyor line 2.

[0115] The conveying direction of conveyor line 1 is the same as the conveying direction of the first conveying mechanism, and the conveying direction of conveyor line 2 is the same as the conveying direction of the second conveying mechanism 2.

[0116] Embodiment 2:

[0117] A conveyor line includes a line changing device, and also includes a conveyor line 1 and a conveyor line 2 which are perpendicular to each other. The bearing surface of the conveyor line 1 is higher than the bearing surface of the conveyor line 2. The line changing device is used to transport the pallets on the conveyor line 1 to the conveyor line 2.

[0118] like Figure 7 As shown, the line changing device is located at the corner where the conveying line 1 and the conveying line 2 are close to each other.

[0119] Embodiment 3: Figure 8 As shown, the line-changing device is located in the middle of the conveyor line 2. At this time, the conveyor line 2 located on both sides of the line-changing device are respectively recorded as the first conveying section and the second conveying section. When the first conveying section of the conveyor line 2 transports the pallet to the second conveying section, the conveyor belt 4 is driven by the first driving assembly 6 to move, and then the supporting mechanism 5 is driven to be transported downward so that it will not interfere with the transportation of the pallet. The bearing surfaces of the multiple rollers 201 in the second conveying mechanism 2 and the bearing surface of the conveyor line 2 are located in the same plane, and the pallet on the first conveying section can be directly transported to the second conveying section.

[0120] The first baffle plate 3 is arranged on the side of the mounting frame 1 away from the conveyor line 1, and the second baffle plate 8 is arranged on the side of the mounting frame 1 close to the conveyor line 1. When the pallet on the conveyor line 1 is transported over, the second baffle plate 8 is driven by the second driving assembly 7 to move below the bearing surface of the support mechanism 5 so as not to hinder the transportation of the pallet. The bearing surface of the support mechanism 5 and the bearing surface of the conveyor line 1 are located in the same plane (i.e., at the same height).

[0121] The fixed ends of the base plate 705 and the cylinder 704 can also be fixed to the frame of the conveyor line 1.

[0122] In the description of the present invention, it should be noted that the terms "upper", "lower", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0123] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a connection between the inside of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, in the description of the present invention, unless otherwise specified, "plurality" means two or more.
