Description

Technical Field

[0001] The invention belongs to the technical field of production equipment for switch panels, and particularly relates to an automatic boxing production line for switch panels. Background Art

[0002] Existing switch panel production lines generally include an injection molding machine, a conveyor belt, and a blanking device. Specifically, the injection molding machine injects the switch panel, which is then transferred by a robotic arm to a conveyor belt. The conveyor belt then transports it to a downstream blanking device. The clamping claws or robotic arms in the blanking device pick up the switch panel on the conveyor belt and transfer it to a pallet or packaging box, thereby facilitating the subsequent packaging of the switch panel. Existing production lines generally have only one blanking device, which is inefficient. If multiple blanking devices are provided, when multiple blanking devices simultaneously pick up switch panels from the same conveyor belt, since there is only one conveyor belt and its width is generally much larger than the size of the switch panel, the position of the switch panels on the conveyor belt is disordered. Multiple clamping claws or robotic arms will interfere with each other, which will still affect the picking efficiency of the blanking device, thereby affecting the working efficiency of the entire production line.

[0003] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

The conveyor belts in all the transport mechanisms are stacked up and down. Along the transport direction of the switch panel, the size of the upper transport mechanism is smaller than the size of the lower transport mechanism, and both ends of the lower transport mechanism protrude from both ends of the upper transport mechanism.

[0027] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0028] like Figures 1 to 3 As shown, an automatic packaging production line for switch panels in one embodiment of the present invention includes an injection molding device 1, a transport device 2, and a plurality of unloading devices 3 arranged in sequence along the transport direction of the switch panels 5.

[0029] It can be understood that the automatic packing production line for switch panels of the present invention changes a conventional wide conveyor belt 233 into multiple narrow conveyor belts 233 arranged in parallel (the width of the conveyor belt 233 matches the switch panel 5), and makes the unloading device 3 correspond to the transmission belt one-to-one. Each unloading device 3 only picks up the switch panel 5 on the corresponding conveyor belt 233, avoiding mutual interference between different unloading devices 3 when picking up and transferring the switch panel 5, and at the same time improving the working efficiency of the unloading device 3 and the working efficiency of the entire automatic packing production line.

[0030] like Figure 1 As shown, the injection molding device 1 includes a device body 11 for producing a switch panel 5 and a transfer mechanism 12 for transferring the switch panel 5 produced by the device body 11 to the transport device 2. The device body 11 can be a common injection molding machine on the market, which can form the switch panel 5 by injection molding. The transfer mechanism 12 can be a common automated robotic arm structure on the market, such as a six-axis robotic arm, the end of which is provided with a clamping claw or a suction cup structure, which can transfer the switch panel 5 produced by the injection molding machine to the transport device 2. The transfer mechanism 12 can also be formed by assembling a common X-axis displacement platform, a Y-axis displacement platform, a Z-axis displacement platform and an electric clamping claw or suction cup structure on the market, so that the electric clamping claw or suction cup structure can be moved in the XYZ coordinate system, thereby realizing the transfer of the switch panel 5 produced by the injection molding machine to the transport device 2.

[0031] In this embodiment, the automatic packing production line includes a plurality of injection molding devices 1 arranged in sequence along the movement direction of the switch panel 5 on the transport device 2, thereby improving the working efficiency of the switch panel 5.

[0032] like Figure 1 and Figure 2As shown, the transport device 2 includes a frame 21, a driving mechanism 22 and a transport mechanism 23. The transport mechanism 23 includes a driving roller 231, a driven roller 232 and a plurality of conveyor belts 233. The driving mechanism 22 is installed on the frame 21. The driving roller 231 and the driven roller 232 are respectively rotatably installed on the frame 21. The output end of the driving mechanism 22 is connected to the driving roller 231 for transmission. All the conveyor belts 233 are arranged in parallel and at intervals between the driving roller 231 and the driven roller 232. The width of the conveyor belt 233 matches the size of the switch panel 5.

[0033] It can be understood that the driving mechanism 22 drives the driving roller 231 to rotate, and the driving roller 231 drives multiple conveyor belts 233 to rotate synchronously. Multiple injection molding devices 1 can transfer the produced switch panels 5 to different conveyor belts 233 respectively. There are also multiple unloading devices 3, and the unloading devices 3 correspond one-to-one to the conveyor belts 233. Each one picks up the switch panel 5 on the corresponding conveyor belt 233, avoiding mutual interference between multiple unloading devices 3 when picking up and transferring the switch panels 5.

[0034] The width of the conveyor belt 233 matches the size of the switch panel 5, that is, the size of the conveyor belt 233 can be slightly larger than the switch panel 5, which improves the orderliness of the switch panels 5 on the conveyor belt 233 and facilitates the unloading device 3 to pick up the switch panel 5 on the conveyor belt 233. The drive mechanism 22 can be a common motor on the market. The drive mechanism 22 can be connected to the drive roller 231 via a transmission member, which can be a transmission belt. The transmission belt is wound between the output end of the drive mechanism 22 and the drive roller 231. In this embodiment, the transport mechanism 23 includes six parallel conveyor belts 233, all of which are wound around the same drive roller 231 and driven roller 232. There are also six unloading devices 3 corresponding to the transport mechanism 23, and each unloading device 3 picks up a switch panel 5 on the conveyor belt 233.

[0035] Further, such as Figure 1 and Figure 3 As shown, each conveyor belt 233 is provided with a partition 24 on both sides of the transport direction of the switch panel 5 thereon, so that the switch panel 5 can be further restricted on the conveyor belt 233, the orderliness of the switch panel 5 on the conveyor belt 233 is improved, and the switch panel 5 is prevented from moving to other conveyor belts 233, which facilitates the unloading device 3 to pick up the switch panel 5 on the corresponding conveyor belt 233.

[0036] Specifically, the conveyor belt 233 is wound between the driving roller 231 and the driven roller 232. Therefore, each conveyor belt 233 is divided into two layers, upper and lower, between the driving roller 231 and the driven roller 232. Therefore, a portion of the frame 21 is protruded between the upper and lower layers of each conveyor belt 233, and adjacent conveyor belts 233 are spaced apart. Therefore, the bottom of the partition 24 passes through the gap between adjacent conveyor belts 233 and is connected to the frame 21, thereby achieving the fixed installation of the partition 24. In other embodiments, the partition 24 can also be connected to the frame 21 in other ways.

[0037] In addition, in order to improve the supporting strength of the conveyor belt 233, a plurality of auxiliary rollers 234 can be provided between the driving roller 231 and the driven roller 232. The auxiliary rollers 234 are provided between the upper and lower layers of each conveyor belt 233 and are rotatably connected to the frame 21.

[0038] Furthermore, there can be multiple drive mechanisms 22, and some auxiliary rollers 234 can be connected to the drive mechanism 22 for transmission. The connection method refers to the transmission connection between the drive roller 231 and the drive mechanism 22, thereby improving the working power of the conveyor belt 233.

[0039] Furthermore, the transport mechanism 23 also includes a baffle 25, and a baffle 25 is provided above each conveyor belt 233. The baffle 25 is connected to the partition 24. Along the transport direction of the switch panel 5 on the conveyor belt 233, the baffle 25 can be against the switch panel 5, and the position of the baffle 25 corresponds to the unloading device 3; with such a setting, the switch panel 5 on the conveyor belt 233 can be stopped at the baffle 25, so that the unloading device 3 can pick up the switch panel 5 stopped by the baffle 25, thereby reducing the difficulty of the unloading device 3 picking up the switch panel 5.

[0040] Preferably, along the transport direction of the switch panels 5 on the transport device 2, the baffles 25 on different conveyor belts 233 are positioned at different locations, and each baffle 25 corresponds to a respective unloading device 3. That is, the baffles 25 on each conveyor belt 233 are positioned at different locations along the transport direction of the switch panels 5 on the transport device 2, thereby reducing the degree of interference between the different unloading devices 3 when picking up the switch panels 5.

[0041] Specifically, the baffle 25 includes a blocking portion 251 and connecting portions 252 bent and connected to opposite sides of the blocking portion 251. The connecting portions 252 are connected to the partition 24. The connecting portions 252 and the baffle 25 can enclose a storage space, which can accommodate multiple switch panels 5. The blocking portion 251 and the connecting portion 252 can be integrally formed. The two connecting portions 252 are respectively connected to the partitions 24 on both sides of the conveyor belt 233 to improve the stability of the connection between the baffle 25 and the partition 24. The blocking portion 251 and the connecting portion 252 can also be connected by other methods, such as bonding, screwing, or clamping. A gap is provided between the bottom of the baffle 25 and the conveyor belt 233 to prevent the baffle 25 from abrading the conveyor belt 233. The connection between the connecting portion 252 and the partition 24 can be specifically connected by common connection methods such as clamping, welding, bonding, or screwing.

[0042] Furthermore, a pressure sensor 26 is provided on the barrier portion 251 to identify whether a panel is abutting the barrier portion 251. The pressure sensor 26 is signal-connected to the unloading device 3. That is, when the switch panel 5 on the conveyor belt 233 abuts the barrier portion 251, it also abuts the pressure sensor 26. After sensing the pressure, the pressure sensor 26 transmits a signal to the unloading device 3. Upon receiving the signal, the unloading device 3 activates and picks up the switch panel 5 on the conveyor belt 233. The pressure sensor 26 is a common commercially available pressure sensor.

[0043] The blocking portion 251 may be provided with a through hole extending along the transport direction of the switch panel 5 on the conveyor belt 233 , and a portion of the pressure sensor 26 may be passed through the through hole to abut against the switch panel 5 .

[0044] In this embodiment, a visual sensor 27 is mounted on the partition 24. The visual sensor 27 is spaced apart from the blocking portion 251 and positioned above the conveyor belt 233. The visual sensor 27 is used to capture image information on the conveyor belt 233. The visual sensor 27 is signal-connected to the unloading device 3. Based on the image information transmitted by the recognition sensor, it can be determined whether the switch panel 5 on the conveyor belt 233 is defective or whether the switch panel 5 is stuck between the two partitions 24. If the switch panel 5 is identified as defective, the unloading device 3 can determine which switch panel 5 intercepted by the baffle 25 is defective based on the information and then pick up another switch panel 5. Alternatively, the unloading device 3 can transfer the defective panel to a designated area, such as a waste bin. If the switch panel 5 is determined to be stuck between the two partitions 24, the unloading device 3 can directly pick up the stuck switch panel 5 or remove it manually or through other devices.

[0045] The distance between the visual sensor 27 and the baffle 25 should not be too large to avoid affecting the operation of the unloading device 3 corresponding to the other conveyor belts 233. Preferably, in this embodiment, the distance between the visual sensor 27 and the baffle 25 is preferably 5 to 6 panel sizes. The visual sensor 27 can be a common industrial camera on the market.

[0046] The signal connection in this embodiment may be a wired connection or a wireless connection.

[0047] like Figure 1 and Figure 2 As shown, the transport device 2 in this embodiment includes two groups of transport mechanisms 23, which are stacked up and down. Along the transport direction of the switch panel 5, the size of the transport mechanism 23 located above is smaller than the size of the transport mechanism 23 located below, and both ends of the transport mechanism 23 located below protrude from both ends of the transport mechanism 23 located above.

[0048] It is understandable that if Figure 1 and Figure 2 As shown, along the transport direction of the switch panel 5 on the transport mechanism 23 (ie Figure 1 and Figure 2 In the direction from left to right in the figure), the upstream end of the lower transport mechanism 23 is located to the left of the upstream end of the upper transport mechanism 23, and the downstream end of the lower transport mechanism 23 is located to the right of the downstream end of the upper transport mechanism 23. Since the two sets of conveyors are stacked up and down, the injection molding device 1 can easily transfer the produced switch panel 5 to the upper transport mechanism 23, and the unloading device 3 can also easily pick up the switch panel 5 on the upper transport mechanism 23 without any obstruction. Along the transport direction of the switch panel 5, both ends of the lower transport mechanism 23 protrude from the two ends of the upper transport mechanism 23, and are respectively used for the injection molding device 1 to transfer the produced switch panel 5 to the lower transport mechanism 23, and for the unloading device 3 to pick up the switch panel 5 on the lower transport mechanism 23. This arrangement can avoid the obstruction of the upper transport mechanism 23 and increase work efficiency.

[0049] Among them, the number of injection molding devices 1 and unloading devices 3 can correspond to the number of transportation mechanisms 23 and the number of conveyor belts 233 on the transportation mechanisms 23; for example, there are two groups of transportation mechanisms 23 stacked up and down, one group of transportation mechanisms 23 includes six conveyor belts 233, and the other group of transportation mechanisms 23 includes four conveyor belts 233. The number of injection molding devices 1 and unloading devices 3 are ten respectively, that is, each injection molding device 1 and unloading device 3 corresponds to a conveyor belt 233, thereby maximizing the working efficiency of the entire automatic packaging production line.

[0050] like Figure 1and Figure 2 As shown, the automatic packing production line of this embodiment includes multiple unloading devices 3, which are located on one side of the transportation mechanism 23 and are arranged in sequence along the transportation direction of the switch panel 5 on the conveyor belt 233, thereby reducing the occupied space of the automatic packing production line; each unloading device 3 corresponds to a conveyor belt 233, and is used to pick up the switch panel 5 on the corresponding conveyor belt 233.

[0051] Specifically, the unloading device 3 includes a unloading conveying mechanism and a unloading robot arm 31. The unloading conveying mechanism is provided with a tray 4. The unloading robot arm 31 is used to pick up the switch panel 5 on the transport device 2 and transfer it to the tray 4 of the unloading conveying mechanism, thereby completing the packing process of the switch panel 5; wherein, the unloading conveying mechanism can be a common conveyor belt structure or other conveying mechanism on the market, and the unloading robot arm 31 can be a common multi-axis robot arm on the market, with a clamping claw or a suction cup at the end, thereby realizing the picking and transfer functions of the switch panel 5.

[0052] In this embodiment, the injection molding device 1, the transportation device 2 and the unloading device 3 can all include a control module. The control module can be a common host computer or PLC module on the market, etc. The control modules in the injection molding device 1, the transportation device 2 and the unloading device 3 can be connected to each other by signal, which can improve the degree of automation of the entire automatic packaging production line.

[0053] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0054] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
