Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of workpiece flipping, in particular to a thin workpiece conveying and processing device. BACKGROUND

[0002] In the existing conveying process of thin brittle workpieces, some workpieces have glue on the upward side, and the subsequent operation requires the side with glue to be downward and the side without glue to be adsorbed (such as the conveying of battery pieces). Therefore, the workpieces need to be flipped.

[0003] However, the conventional flipping structure in the prior art flips one piece at a time, or some flipping structures can flip multiple pieces, which are slot type. Such flipping structure is matched with a belt conveying line, and after the workpiece is flipped by 180 degrees, it also needs to be sent out by the belt conveying line. Therefore, it cannot adapt to some application scenarios, for example, when the workpiece has glue on one side, the workpiece is preferably allowed to fall by gravity after being flipped. If the existing slot type flipping structure is used, the workpiece cannot fall. Moreover, the flipping structure in the prior art does not fix the workpiece, and the workpiece may be shifted during the flipping process. CONTENT OF THE UTILITY MODEL

[0038] With reference to Figure 1 and Figure 2 , Figure 4As shown, the present application proposes a thin workpiece conveying and processing device. The thin workpiece conveying and processing device comprises at least one belt conveying line 1 for conveying workpieces 200 and a turnover device 2. Each belt conveying line 1 comprises at least two groups of belt mechanisms 11 arranged side by side and spaced apart, and a turnover gap 111 is formed between the two adjacent groups of belt mechanisms 11, and the belt conveying line 1 conveys the workpieces 200 in a first direction; the turnover device 2 comprises a turnover driving executive member 21, a rotating main shaft 22 connected with the turnover driving executive member 21, and at least one adsorption rod group 23 arranged on the rotating main shaft 22; a plurality of adsorption rods 231 in each adsorption rod group 23 are arranged spaced apart along the axial direction of the rotating main shaft 22, the turnover driving executive member 21 drives the rotating main shaft 22 to rotate and in turn drives each adsorption rod group 23 to rotate, so that the adsorption rods 231 in the adsorption rod group 23 adhere to and adsorb the workpieces 200 on the belt conveying line 1 from below through the turnover gap 111, and drive the adsorbed workpieces 200 to turn over; the rotating main shaft 22 extends in a second direction, and the adsorption rods 231 extend in a first direction, and the second direction is perpendicular to the first direction.

[0039] Preferably, the adsorption surfaces of the plurality of adsorption rods 231 of the same adsorption rod group 23 are located in the same plane, so as to stably adsorb the sheet-shaped workpieces 200 on the belt conveying line 1. When the workpieces 200 are provided with dispensing on the upper surface, the adsorption rods 231 in the adsorption rod group 23 adhere to and adsorb the workpieces 200 on the belt conveying line 1 from below, without colliding with the dispensing on the workpieces 200.

[0040] In the technical scheme of the present application, the position and structure of the belt conveying line 1 and the turnover device 2 are cooperatively designed, so that based on the rotating action of the adsorption rods 231, the adsorption rods 231 vacuum-adsorb the workpieces 200 and drive them to turn over. On the one hand, the adsorption rods 231 have a vacuum adsorption function, which can form a good fixation of the workpieces 200 based on vacuum adsorption, improve the stability in the turnover process, and make the workpieces 200 not easy to deviate in the turnover process; on the other hand, based on the corresponding relationship between the adsorption rods 231 and the workpieces 200 on the belt conveying line 1, when the adsorption rods 231 rotate and correspond to a plurality of workpieces 200 above at the same time, a plurality of workpieces 200 can be vacuum-adsorbed at the same time, the synchronous turnover of the plurality of workpieces 200 is completed, and the turnover efficiency is improved.

[0041] Specifically, when the plurality of belt conveying lines 1 are provided, the plurality of belt conveying lines 1 are arranged side by side, and the turnover device 2 is arranged to interface the output ends of the plurality of belt conveying lines 1 at the same time to simultaneously turn over the workpieces 200 on the plurality of belt conveying lines. For example, the plurality of belt conveying lines 1 in the present application are arranged side by side in two, and each belt conveying line 1 includes three groups of belt mechanisms 11 arranged side by side and at intervals. In the turnover device 2, the number of adsorption rods 231 in the adsorption rod group 23 is four, and each two adsorption rods 231 form a group and correspond to the turnover gaps 111 of the two belt conveying lines 1, respectively. Thus, in the adsorption and turnover process, the two adsorption rods 231 in each group can jointly adsorb and fix the corresponding workpiece 200, thereby improving the stability of the workpiece 200 in the adsorption and turnover process.

[0042] It is worth noting that the number of adsorption rod groups 23 can be set to multiple groups, such as two groups, four groups, six groups, or more. The multiple groups of adsorption rod groups 23 are arranged at intervals around the rotating main shaft 22. When a plurality of groups are arranged, the turnover efficiency can be improved, the conveying speed of the workpieces 200 on the belt conveying line 1 can be adjusted, and the turnover process can also serve as a buffer. Assuming that the number of adsorption rod groups 23 is n, where n satisfies: 180 can be evenly divided by 360 / n.

[0043] Preferably, the number of adsorption rod groups 23 is set to four, that is, four adsorption and turnover stations are arranged. At this time, the turnover driving executive member 21 drives each group of adsorption rod groups 23 to rotate 90° each time. In the rotation process of the rotating main shaft 22, the turnover operation of the workpieces 200 on the belt conveying line 1 is alternately implemented, thereby further improving the turnover efficiency of the workpieces 200.

[0044] In a specific arrangement, the turnover device 2 further includes a driving bearing seat 24 and a driven bearing seat 25. The rotating main shaft 22 is arranged to rotate on the driving bearing seat 24 and the driven bearing seat 25. The turnover driving executive member 21 can be a combination of a driving motor, a speed reducer, a synchronous belt, and a synchronous wheel to generate and transmit power to drive the rotating main shaft 22 to rotate.

[0045] In some embodiments, the rotating main shaft 22 and each adsorption rod 231 are provided with a communication air channel, and a plurality of adsorption holes are formed on the adsorption rod 231 and communicate with the air channel; the air channel of the rotating main shaft 22 communicates with the vacuum system 26.

[0046] In this embodiment, when the vacuum system 26 is communicated with the rotating main shaft 22, the vacuum system 26 works to generate negative pressure (i.e. suction force), which is transmitted to each adsorption rod 231 through the air channel and finally acts on the workpiece 200 to be adsorbed through the adsorption hole. Since the adsorption hole is communicated with the air channel, the whole system can form a communicated negative pressure area, thereby realizing stable adsorption of the workpiece 200, and with the rotation of the rotating main shaft 22, the adsorption rod 231 drives the adsorbed workpiece 200 to overturn.

[0047] Further, as shown in Figure 2 the vacuum system 26 includes a vacuum generator 261 and an air slip ring 262, the vacuum generator 261 is communicated with the air channel of the rotating main shaft 22 through the air slip ring 262. Among them, the vacuum generator 261 is used to generate negative pressure, and the air slip ring 262 can allow gas to be transmitted between the rotating part and the fixed part, so that the rotating main shaft 22 can still be effectively communicated with the vacuum system 26 while keeping continuous rotation, so that the adsorption rod 231 provides stable and continuous adsorption force to firmly fix the workpiece 200.

[0048] Referring to Figure 3 in some embodiments, the overturning device 2 further includes an anti-rotation mechanism 27, the anti-rotation mechanism 27 includes a ratchet wheel 271 and a pawl 272, the ratchet wheel 271 is coaxially connected with the rotating main shaft 22; the pawl 272 is fixedly arranged on one side of the ratchet wheel 271, which can be fixed on the driven bearing seat 25, and is used to cooperate with the ratchet wheel 271 to prevent the rotating main shaft 22 from rotating reversely.

[0049] In this embodiment, the ratchet wheel 271 is a circular wheel with a tooth shape, which is coaxially connected with the rotating main shaft 22, and the pawl 272 is a relatively fixed part, which is located on one side of the ratchet wheel 271 and cooperates with the tooth shape of the ratchet wheel 271, so that the pawl 272 can prevent the rotating main shaft 22 from rotating reversely by meshing with the tooth shape of the ratchet wheel 271 when the ratchet wheel 271 tries to rotate reversely.

[0050] It can be understood that when the rotating main shaft 22 rotates under the forward driving, the tooth shape of the ratchet wheel 271 does not interfere with the pawl 272, and the ratchet wheel 271 can rotate smoothly. At this time, the pawl 272 only passively moves with the rotation of the ratchet wheel 271, but does not generate resistance to it. If the rotating main shaft 22 tries to rotate reversely, the tooth shape of the ratchet wheel 271 will mesh with the pawl 272. Since the pawl 272 is relatively fixed, it will prevent the ratchet wheel 271 from further rotating reversely. Since the ratchet wheel 271 is coaxially connected with the rotating main shaft 22, the reverse rotation of the rotating main shaft 22 will also be prevented. In this way, by introducing the anti-rotation mechanism 27, it can be ensured that the rotating main shaft 22 can only rotate in one direction, avoiding reverse rotation caused by misoperation or external interference, thereby further eliminating the return gap, which helps to maintain the stability and reliability of the overturning operation of the overturning device 2.

[0051] Referring to Figure 6 As shown in some embodiments, the thin workpiece conveying and processing device further comprises a horizontal transfer receiving device 4 for receiving the workpiece 200 after being flipped by the flipping device 2; the horizontal transfer receiving device 4 comprises a driving mechanism 43 and a plurality of suction arms 41. The plurality of suction arms 41 are arranged side by side and at intervals, and are synchronously slidingly arranged on a machine table 410, at least two adjacent suction arms 41 forming a suction group for receiving a suction workpiece 200, and a group of the suction groups is used to receive a row of battery pieces; the driving mechanism 43 is connected with the plurality of suction arms 41, and is used to drive the plurality of suction arms 41 to reciprocate between a receiving point and a discharging point. The receiving point is located at a position after the flipping device 2 is flipped into place, and the discharging point is a position where the battery pieces are taken away.

[0052] In the embodiment, the plurality of suction arms 41 can be connected by connecting rods 42 to achieve synchronous sliding, thereby ensuring the synchronization of each suction arm 41 during movement. When the driving mechanism 43 is started, all the suction arms 41 synchronously realize reciprocation between the receiving point and the discharging point. A guide sliding structure 412, such as a sliding rail and sliding groove matching structure, can be further arranged between the plurality of suction arms 41 and the machine table 410 to improve the movement precision and stability of the horizontal transfer receiving device 4, and facilitate maintaining the correct direction and position at all times.

[0053] Further, an avoidance gap 411 is formed in the suction group, which is used for the suction rod 231 to rotate and extend in to make the workpiece 200 on it fit the suction arm 41 and be suctioned to the corresponding suction group. A cooperation process between the horizontal transfer receiving device 4 and the flipping device 2 is as follows:

[0054] The driving mechanism 43 drives the plurality of suction arms 41 to slide to the receiving point, the rotation of the rotating main shaft 22 in the flipping device 2 drives the suction rod 231 to flip the workpiece 200, and as the rotating main shaft 22 further rotates, the suction rod 231 rotates and extends into the avoidance gap 411, and the workpiece 200 suctioned on it can be lapped on the suction arm 41 in the suction group, and then under the condition that the suction rod 231 breaks the vacuum and the suction arm 41 opens the vacuum, the workpiece 200 is suctioned on the suction arm 41, and then the driving mechanism 43 drives the suction arm 41 to slide the workpiece 200 to the discharging point for discharging.

[0055] To realize vacuum suction of the suction arm 41, a gas channel is also arranged in the suction arm 41, and a suction hole communicating with the gas channel is formed on the suction arm 41, and a vacuum system is provided to generate vacuum suction conditions. The vacuum system in the horizontal transfer receiving device 4 is independent of the vacuum system in the flipping device 2.

[0056] It is worth noting that during the sliding of the adsorption arm 41 to the unloading point, the turnover device 2 continues to work, so that the adsorption rod group 23 with another workpiece 200 adsorbed is turned over above the receiving point. After the adsorption arm 41 slides back to the receiving point, the above matching process is repeated to complete the transfer and unloading of the workpiece 200. In this way, based on the cooperative work of the turnover device 2 and the horizontal transfer receiving device 4, through the continuous turnover of the turnover device 2 and the rapid reciprocating movement of the horizontal transfer receiving device 4, the efficient processing of the workpiece 200 is realized, which is conducive to improving the production capacity and efficiency of the production line.

[0057] Referring to Figure 6 As shown in some embodiments, the horizontal transfer receiving device 4 further comprises a transmission mechanism 44, which comprises a connecting piece 444, a driving synchronous wheel 441, a driven synchronous wheel 442 and a synchronous belt 443 connecting the driving synchronous wheel 441 and the driven synchronous wheel 442; the driving synchronous wheel 441 is connected with the driving mechanism 43, when the driving mechanism 43 such as motor is started, it will drive the driving synchronous wheel 441 to rotate, and further drive the synchronous belt 443 to move, and the connecting piece 444 is arranged on the synchronous belt 443 and connected with the plurality of adsorption arms 41, so that when the synchronous belt 443 moves, the plurality of adsorption arms 41 can be simultaneously driven to reciprocate relative to the machine table 410 under the cooperation of the guide sliding structure 412 through the connecting piece 444. Based on this, the transmission mechanism 44 can quickly and efficiently transmit power to realize the reciprocating movement of the adsorption arm 41.

[0058] Referring to Figure 4 and Figure 5As shown, in some embodiments, the thin workpiece conveying and processing device further comprises a centering device 3. The centering device 3 comprises a plurality of guide and lifting units 31 and a driving assembly 32; one belt conveying line 1 is arranged between any two adjacent guide and lifting units 31. The plurality of guide and lifting units 31 are arranged side by side and spaced apart along the second direction, and each guide and lifting unit 31 comprises a support vertical plate 311, a lifting and guiding assembly 312, and a transmission assembly 33. The lifting and guiding assembly 312 comprises a support frame 3121 and a plurality of guide wedges 3122 connected to the support frame 3121. The plurality of guide wedges 3122 are arranged in one or two rows, and the plurality of guide wedges 3122 in each row are arranged spaced apart along the first direction. The support frame 3121 is slidingly connected to the support vertical plate 311 along the vertical direction, so that the support frame 3121 can move up and down along the vertical direction relative to the support vertical plate 311 to center the workpiece by the guide wedges 3122 of the adjacent two lifting and guiding assemblies 312. The transmission assembly 33 is connected to the driving assembly 32 and is used to drive the lifting and guiding assembly 312 to lift. The transmission assembly 33 drives the lifting and guiding assembly 312 to lift in various ways, for example, a lifting cam 34 cooperates with a rolling part 35, at this time the transmission assembly 33 is in motion contact with the lifting and guiding assembly 312; for example, the transmission assembly 33 is a connecting rod assembly, one end of the connecting rod assembly is connected to the driving assembly 32, and the other end is connected to the support frame 3121, so that the transmission assembly 33 in this form can also drive the lifting and guiding assembly 312 to lift, of course, the structure of the transmission assembly 33 is not limited to the examples shown in the present application.

[0059] In the present application, the number of guide and lifting units 31 is at least two, when the number is exactly two, it is only used for the centering and positioning of one row of battery pieces. The number of guide and lifting units 31 can also be greater than two, which is used for the centering and positioning of at least two rows of battery pieces, at this time, the adjacent two lifting and guiding assemblies 312 form a group to constitute one centering device. The space between the adjacent two lifting and guiding assemblies 312 is used for centering and clamping the workpiece.

[0060] The driving assembly 32 comprises a driving executive part 322 and a driving shaft 321 connected to the driving executive part 322. The driving shaft 321 is in transmission connection with the transmission assembly 33 in each guide and lifting unit 31, and then drives each lifting and guiding assembly 312 to lift through the driving executive part 322, so that the guide wedges 3122 on the adjacent lifting and guiding assemblies 312 center and position the workpiece therebetween. Specifically, the driving executive part 322 is, for example, a motor.

[0061] The technical solution of this application aims to output power through the drive component 32 and transmit power through the transmission component 33 to synchronously drive multiple lifting and guiding components 312 to perform lifting and lowering movements. During the upward movement of the multiple lifting and guiding components 312, the guiding wedges 3122 on adjacent lifting and guiding components 312 contact a row of workpieces. Based on the limiting and guiding effect of the guiding wedges 3122, the workpieces between adjacent lifting and guiding components 312 are aligned under their own gravity. The device is simple and has a compact structure.

[0062] See Figure 5 As shown, the guide wedges 3122 on adjacent support frames 3121 are arranged opposite each other. Each guide wedge 3122 has a guide slope 3123 on its opposite side, and the guide slopes 3123 of the two adjacent lifting guide components 312 are inclined inward from top to bottom, that is, inclined towards each other. In this way, an inverted isosceles trapezoidal guide space is formed between the two opposite guide wedges 3122, and this guide space is actually a limiting space for the workpiece between them.

[0063] During operation, adjacent lifting and guiding components 312 rise synchronously and then fall. Through one (this case is suitable for materials with a good posture so only one) or multiple lifting and lowering of the guiding wedges 3122, the workpiece is centered under the action of the guiding inclined surface 3123 and gravity.

[0064] See Figure 7 As shown, in some embodiments, the thin workpiece conveying and processing equipment further includes at least one set of pitch adjustment devices 5. Each pitch adjustment device 5 is connected one-to-one with the input end of the belt conveyor 1, meaning the number of pitch adjustment devices 5 is the same as the number of belt conveyors 1, ensuring that the spacing of each row of battery cells conveyed to the belt conveyor 1 has been adjusted. The arrangement of these pitch adjustment devices 5 is intended to pre-adjust the spacing between several workpieces 200 before they enter the belt conveyor 1, thereby ensuring that the workpieces 200 can proceed according to a predetermined layout during subsequent processing.

[0065] Each pitch adjustment device 5 includes multiple coarse positioning belts 51 and multiple sensors 52. The coarse positioning belts 51 are arranged sequentially along the conveying direction of the workpiece 200. Each coarse positioning belt 51 includes at least two sub-belt mechanisms arranged side-by-side and spaced apart. These sub-belt mechanisms are connected to the same drive shaft 53, thus enabling synchronous conveying of the workpiece 200, reducing bending deformation of thin workpieces due to their own weight, and improving conveying stability. The conveying direction of the workpiece 200 is a first direction, and the at least two sub-belt mechanisms are spaced apart along a second direction, perpendicular to the first direction. To monitor the position of the workpiece 200 on each coarse positioning belt 51 in real time, each coarse positioning belt 51 is equipped with a corresponding sensor 52. When the sensor 52 detects a workpiece 200 on the corresponding coarse positioning belt 51, it triggers a pitch adjustment mechanism. This mechanism adjusts the transmission speed of each coarse positioning belt 51 according to a preset spacing requirement, ensuring that each workpiece 200 is conveyed at the preset spacing after adjustment.

[0066] It is worth noting that during the spacing adjustment of workpieces 200, there is no overlap between each workpiece 200 and the adjacent coarse positioning belt 51, thus ensuring that the speed adjustment zone of each workpiece 200 is only on the same coarse positioning belt 51, achieving position controllability and preventing the workpiece 200 from shifting in the conveying direction due to the speed difference of adjacent coarse positioning belts.

[0067] See Figure 7 As shown, in some embodiments, each pitch adjustment device 5 further includes a pre-alignment mechanism 54 to initially achieve the alignment position adjustment of each workpiece 200.

[0068] The pre-alignment mechanism 54 includes clamping members 541 arranged opposite each other and a driving member (not shown in the figure) for driving the clamping members 541 to move closer or further apart. Multiple thick positioning belts 51 are arranged between the clamping members 541 so that, driven by the driving member, the clamping members 541 simultaneously squeeze the workpieces 200 on the multiple thick positioning belts 51 to align them in a straight line in the conveying direction. The driving member can be a double-headed cylinder that simultaneously pushes or pulls the clamping members 541. Rollers are arranged at intervals on the clamping members 541 along the conveying direction of the workpieces 200 so that the clamping members 541 and the workpieces 200 make rolling contact.

[0069] In summary, the technical solution of this application, according to the conveying sequence of workpieces 200, sequentially includes a pitch adjustment device 5, a belt conveyor line 1, a flipping device 2, and a transverse receiving device. Several workpieces 200 are spaced and adjusted at intervals on the pitch adjustment device 5 so that each workpiece 200 is conveyed to the belt conveyor line 1 at a predetermined interval, and pre-alignment is performed on the pitch adjustment device 5. A matching alignment device 3 is provided at the belt conveyor line 1. If needed, this alignment device 3 can further achieve precise alignment of the workpieces 200. Then, the flipping device 2 performs a flipping operation, realizing the flipping of the workpieces 200 on the belt conveyor line 1. This flipping can achieve the flipping of multiple workpieces 200 at once, and the flipped workpieces 200 are transferred to the transverse receiving device. Based on the structural cooperation between the transverse receiving device and the flipping device 2, the receiving, transfer, and unloading of the workpieces 200 are completed.

[0070] This thin workpiece conveying and processing equipment includes at least one belt conveyor 1 for conveying workpieces and a flipping device 2. In this application's technical solution, through the positional and structural design of the belt conveyor 1 and the flipping device 2, the rotating main shaft 22 in the flipping device 2 drives the adsorption rod assembly 23 to rotate. The adsorption rods 231 in the adsorption rod assembly 23 can then adhere to and adsorb the workpieces 200 on the belt conveyor 1 from below through the flipping gap 111, thereby causing the adsorbed workpieces 200 to flip. Since the workpieces 200 are vacuum-adsorbed and flipped based on the adsorption rods 231 extending into the belt conveyor 1, on the one hand, vacuum adsorption provides good fixation for the workpieces 200, ensuring stability and preventing them from easily shifting; on the other hand, based on the correspondence between the adsorption rods 231 and the workpieces on the belt conveyor 1, when the adsorption rods 231 rotate and multiple workpieces 200 are simultaneously positioned above them, multiple workpieces 200 can be vacuum-adsorbed simultaneously, completing the synchronous flipping of multiple workpieces 200 and improving flipping efficiency.
