[0002] In order to improve the uniformity and consistency of the paint layer thickness on the surface of keycaps (mainly the keycaps on laptop computers), when spraying paint on the keycaps, it is necessary to install the keycaps on a fixture of a simulated keyboard for spraying. The existing fixture for spraying paint on keycaps includes a substrate (i.e., a backplane, which is made of aluminum), and a carrier plate (generally a plastic carrier plate) is arranged on the substrate, and the keycaps are directly installed on the corresponding keys of the carrier plate.

[0003] When spraying paint on the keycaps, before each spraying, a label with a two-dimensional code is attached to the substrate. The spraying equipment records by scanning the two-dimensional code and then sprays the paint. After the spraying is completed, the aluminum plate needs to be recycled. After recycling, the original label is torn off, a new label is attached, and it waits to be used as a carrier for keycaps for spraying positioning again. In the conventional label tearing method, an operator uses a small knife to lift one side and then tear it off.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0042] The present utility model will be further described below in conjunction with the drawings and embodiments:

[0043] Embodiment 1: Refer to Figures 1 to 6 shown, a fixture backplane label tearing device, comprising:

[0044] frame 1;

[0045] At least one label tearing device, the label tearing device is movably arranged on the frame 1; the label tearing device includes a bracket 2 and at least one group of label tearing components 3 installed on the bracket, the label tearing component 3 includes two oppositely arranged scraping plates 31 and a label tearing driving member 32 for driving the two scraping plates 31 to approach or move away from each other;

[0046] A driving device, the driving device is installed on the frame 1, and the driving device is configured to drive the label tearing device to move between a first position and a second position, and drive the driving device to move vertically at the first position and the second position respectively;

[0047] A cleaning mechanism 4, the cleaning mechanism 4 is arranged on the frame 1 at the second position; the cleaning mechanism 4 is at least one group, and each cleaning mechanism 4 is arranged opposite to a group of label tearing components 3; the cleaning mechanism 4 includes a cleaning component 41 and a cleaning driving member 42, and two cleaning ports 43 are arranged on the cleaning component 41, and the cleaning driving member 42 is configured to drive the cleaning ports 43 to open and close.

[0048] In this embodiment, during actual use, a conveyor belt 5 (or other conveying mechanisms, and manual material picking and placing can also be adopted, depending on the actual situation) is arranged below the first position for conveying the fixture backplane. When the fixture backplane is conveyed to the first position by the conveyor belt, the driving device drives the label tearing device to move to the first position, which is directly above the fixture backplane. At this time, the label tearing assembly is directly above the label to be torn. For example, if the label is a square label, then the two scraping plates are far away from each other and are directly above both ends of the label. Then, the driving device drives the label tearing device to move downward so that the scraping plates abut against the top surface of the end of the label. Then, the label tearing driving member synchronously drives the two scraping plates to approach each other, and the label is scraped and torn inward from both ends by the scraping force of the scraping plates, and the torn label is clamped between the two scraping plates. Then, the driving device drives the label tearing device to move upward away from the fixture backplane and move to the second position. During this process, the conveyor belt will send away the fixture backplane with the label torn off and convey it to the next label pasting process, and at the same time, it will also convey the fixture backplane with the label to be torn off to the first position. After the label tearing device moves to the second position, the two scraping plates will move away from each other, and the label between the two scraping plates will fall off. However, due to the certain adhesiveness of the label itself, the label may adhere to one scraping plate, or the label may be broken and adhered to the two scraping plates respectively, which will affect the label tearing operation of the subsequent fixture backplane. Therefore, after the scraping plates open, the driving device drives the label tearing assembly to move downward. In the initial state, the cleaning ports are in an open state, and each scraping plate is inserted into a cleaning port. The cleaning driving member drives the cleaning ports to close, and the inner and outer sides of the scraping plates are clamped with a certain force through the cleaning ports. Then, the driving device drives the label tearing device to move upward. During this process, the label that may adhere to the scraping plates will be scraped off by the clamping force of the cleaning ports on the scraping plates, so as not to affect the subsequent label tearing operation. Preferably, in the present utility model, the outer surface of the scraping plate has a non-sticky coating to prevent the label from adhering to the scraping plate as much as possible. And the existence of the cleaning mechanism cleans the label that may adhere to it.

[0049] In the present utility model, there can be one or two sets of label tearing devices. The two sets of label tearing devices are arranged at intervals, and the conveyor belt is located between the two sets of label tearing devices. In this way, when one set of label tearing devices is tearing the label, the other set of label tearing devices will release the torn label to make it fall off and clean it through the cleaning mechanism. Alternating in this way can improve the label tearing efficiency. At the same time, according to the number of labels on the fixture backplane, for example, if there are two labels on the fixture backplane that need to be torn off simultaneously, two sets of label tearing assemblies can be installed on one bracket, and each label tearing assembly is arranged opposite to one label. It is also possible that there is one label on one fixture backplane, but there are two sets of label tearing assemblies on the label tearing device, and the label tearing operation is carried out on two fixture backplanes simultaneously, which can improve the label tearing efficiency.

[0050] See Figure 4 、5 As shown, the scraping plate 31 is connected to the label tearing driving member 32 through a scraping plate mounting block 33;

[0051] The outer side of the bottom of the scraping plate 31 is a first guiding inclined surface 34 that slopes inwards from top to bottom, and the first guiding inclined surface 34 makes the bottom of the scraping plate 31 form a triangular or trapezoidal structure.

[0052] In this embodiment, the outer side of the bottom of the scraping plate adopts a first guiding inclined surface, so that the bottom of the scraping plate forms a triangular or trapezoidal structure with a smaller bottom and a larger top, so that the contact area between the bottom of the scraping plate and the label is smaller, so that the bottom of the scraping plate can abut against the end of the label to smoothly tear off the label and ensure the tearing effect.

[0053] See Figure 4 、 5 As shown, the scraping plate mounting block 33 is slidably connected to the bracket 2, and the label tearing driving member 32 is configured to drive the two scraping plate mounting blocks 33 to approach or move away from each other simultaneously. Through the setting of the scraping plate mounting block, when the scraping plate is worn or damaged, the scraping plate can be quickly disassembled and replaced. At the same time, when different types of labels need to be torn off, it is also possible to conveniently and quickly replace the scraping plate adapted to the label.

[0054] Among them, as an embodiment, the label tearing driving member includes a label tearing motor and a label tearing positive and negative lead screw. The label tearing positive and negative lead screw is rotatably connected to the bracket, and the label tearing motor is configured to drive the label tearing positive and negative lead screw to rotate;

[0055] The two scraping plate mounting blocks are respectively screwed to the two ends of the label tearing positive and negative lead screw;

[0056] When the label tearing positive and negative lead screw rotates, it simultaneously drives the two scraping plate mounting blocks to approach or move away from each other.

[0057] In this embodiment, a label tearing positive and negative lead screw is adopted, and positive threads and reverse threads (clockwise threads and counterclockwise bolts with opposite spiral directions) are respectively provided at both ends of the middle part thereof. In this way, when the label tearing motor drives the label tearing positive and negative lead screw to rotate in one direction, it will drive the two scraping plate mounting blocks to approach each other. When the label tearing motor drives the label tearing positive and negative lead screw to rotate in the other direction, it will drive the two scraping plate mounting blocks to move away from each other. The output shaft of the label tearing motor is connected to the end of the label tearing positive and negative lead screw, thereby driving the label tearing positive and negative lead screw to rotate.

[0058] In another embodiment, the label tearing driving member can be two cylinders, and the two cylinders are respectively connected to a scraping plate mounting block. By simultaneously extending and retracting the output shafts of the two cylinders, the two scraping plate mounting blocks are driven to approach or move away from each other simultaneously.

[0059] SeeFigure 2 , 3 As shown in FIG. 6, the cleaning member 41 includes two first cleaning members 44 arranged at intervals and two second cleaning members 45 arranged at intervals. Each of the first cleaning members 44 is respectively arranged beside one of the second cleaning members 45, and a cleaning port 43 is formed between each of the first cleaning members 44 and each of the second cleaning members 45;

[0060] When the label tearing device moves to the second position, each of the scraping plates is arranged opposite to one of the cleaning ports;

[0061] When the label tearing assembly 3 moves downward at the second position, each of the scraping plates 31 is inserted into one of the cleaning ports 43, and the bottom of the scraping plate 31 is arranged below the bottom surface of the cleaning port 43.

[0062] When the label tearing device moves to the second position, each scraping plate is directly above a cleaning port. When the driving device drives the label tearing device and the label tearing assembly to move downward, the corresponding scraping plate is inserted into the corresponding cleaning port. Preferably, the bottom of the scraping plate will be directly below the cleaning port, and at this time, the label will be below the bottom of the cleaning port. Then the cleaning driving member drives the cleaning port to gradually close and clamp on the outer wall of the scraping plate and contact the two side walls of the scraping plate (a second inclined surface matching the first guiding inclined surface is provided on the side wall of one cleaning member). Then the label tearing device and the scraping plate move upward. Since the bottom of the scraping plate is below the cleaning port, that is, the label is below the bottom surfaces of the first cleaning member and the second cleaning member. When the scraping plate moves upward, the bottom side walls of the corresponding cleaning members will scrape off the label that may adhere to the scraping plate, preventing the label from remaining on the scraping plate and not affecting the subsequent label tearing.

[0063] See Figure 2 , 3 As shown in FIGS. 6 and 7, it further includes a first mounting block 46 and a second mounting block 47. The first mounting block 46 and the second mounting block 47 are respectively slidably mounted on the frame 1, and the cleaning driving member 42 is configured to drive the first mounting block 46 and the second mounting block 47 to move relatively or move away from each other;

[0064] The two first cleaning members 44 are spaced and mounted on the first mounting block 46, and the two second cleaning members 45 are spaced and mounted on the second mounting block 47;

[0065] When the first mounting block 46 and the second mounting block 47 move relatively, the corresponding first cleaning member 44 and the corresponding second cleaning member 45 approach each other, and the cleaning port 43 closes;

[0066] When the first mounting block 46 and the second mounting block 47 move away from each other, the corresponding first cleaning member 44 and the corresponding second cleaning member 45 move away from each other, and the cleaning port 43 opens.

[0067] In this embodiment, taking the horizontal diagram as an example, one end of the first mounting block is slidably connected to the frame, one end of the second mounting block is slidably connected to the frame, the other end of the first mounting block is above or below the other end of the second mounting block, and one first cleaning member faces one second cleaning member. In this way, when the first mounting block and the second mounting block move relative to each other or move away from each other, the cleaning port between the corresponding first cleaning member and the second cleaning member can be opened or closed. Among them, the side walls of the first cleaning member and the second cleaning member are respectively matched with the inner side wall and the outer side wall of the scraper. When the cleaning port is closed, the side walls of the first cleaning member and the second cleaning member are respectively in contact with the inner side wall and the outer side wall of the scraper. After the side walls of the first cleaning member, the second cleaning member and the two side walls of the scraper are in contact, when the scraper moves upward, the label that may adhere to the scraper can be scraped off, preventing the label from adhering to the scraper. After the scraper moves upward, the cleaning driving member drives the first mounting block and the second mounting block to move away from each other, so that the corresponding first cleaning member and the second cleaning member move away from each other, opening the cleaning port and waiting for the next time the scraper is inserted into the cleaning port to scrape the label.

[0068] Among them, in one embodiment, the cleaning driving member includes a cleaning motor and a cleaning forward and reverse lead screw. The cleaning forward and reverse lead screw is rotatably connected to the frame, and the cleaning motor is configured to drive the cleaning forward and reverse lead screw to rotate;

[0069] The first mounting block and the second mounting block are respectively screwed to both ends of the cleaning forward and reverse lead screw;

[0070] When the cleaning forward and reverse lead screw rotates, it simultaneously drives the first mounting block and the second mounting block to move relative to each other or move away from each other.

[0071] The cleaning positive and negative lead screws are adopted. At both ends of the middle part of the cleaning positive and negative lead screws, a positive thread and a reverse thread (a clockwise thread and a counterclockwise bolt with opposite spiral directions) are respectively provided. In this way, when the cleaning motor drives the cleaning positive and negative lead screws to rotate in one direction, it will drive the first mounting block and the second mounting block to move relatively, that is, the connection between the first mounting block and the cleaning positive and negative lead screws and the connection between the second mounting block and the cleaning positive and negative lead screws approach each other, so that the corresponding first cleaning part and the second cleaning part approach each other, and the cleaning port gradually closes. When the cleaning motor drives the cleaning positive and negative lead screws to rotate in the other direction, it will drive the first mounting block and the second mounting block to move away from each other, that is, the connection between the first mounting block and the cleaning positive and negative lead screws and the connection between the second mounting block and the cleaning positive and negative lead screws move away from each other, so that the corresponding first cleaning part and the second cleaning part move away from each other, and the cleaning port gradually opens. The output shaft of the cleaning motor is connected to the end of the cleaning positive and negative lead screws, so as to drive the cleaning positive and negative lead screws to rotate.

[0072] In another embodiment, the cleaning driving member can be two cylinders. The two cylinders are respectively connected to the first mounting block and the second mounting block. By simultaneously extending and retracting the output shafts of the two cylinders, the two cleaning ports are driven to open or close.

[0073] See Figures 1 to 3 As shown, on the frame 1 at the second position, there is a receiving box 11 with an open top. The cleaning mechanism 4 is installed on the receiving box 11, and the cleaning component 41 is arranged above the receiving box 11.

[0074] With the setting of the receiving box, when the label tearing device moves to the second position, the two scraping plates in the label tearing assembly move away from each other, so that the torn labels fall downward due to gravity into the receiving box, and the receiving box is used to collect the torn labels, which is convenient for unified collection and processing.

[0075] See Figure 3 、 5 As shown, a pressing plate 21 is further provided at the bottom of the bracket 2. The top of the pressing plate 21 is movably connected to the bracket 2 through a guide rod 22;

[0076] A spring (not shown in the figure) is sleeved on the guide rod 22. The two ends of the spring respectively abut against the top surface of the pressing plate 21 and the bottom surface of the bracket 2. A nut 23 is provided at the top of the guide rod 22, and the nut 23 is arranged above the top surface of the bracket 2;

[0077] When the spring is in the extended state, the nut 23 abuts against the top surface of the bracket 2, and the bottom surface of the pressing plate 21 is arranged below the bottom surface of the scraping plate 31;

[0078] When the spring is in the compressed state, the bottom surface of the nut is far away from the bracket.

[0079] In this embodiment, through the settings of the pressing plate and the spring, when the label tearing device moves downward, during the process that the scraping plate contacts the label and tears the label, the fixture backplane will also be affected by the tearing force. To ensure the stability of tearing and prevent the fixture backplane from moving, therefore, by setting the pressing plate and the spring, when the label tearing device moves downward, the pressing plate will first abut against the fixture backplane, and then continue to move downward. The bracket will compress the spring, and the pressing plate will be pressed against the fixture backplane through the compression force of the spring. Through the elastic force of the pressing plate and the spring, the fixture backplane is pressed against the frame or the conveyor belt. Then, after the scraping plate abuts against the label, the label tearing device moves downward to the place, and then the tearing work is carried out. During the process that the scraping plate moves to tear the label, the scraping force generated is prevented from moving the fixture backplane relative to the frame through the pressure of the pressing plate and the spring on the fixture backplane, thereby ensuring the stability and quality of label tearing. After the tearing is completed, when the label tearing device moves upward, the scraping plate will first disengage from the fixture backplane, and the spring gradually extends. When the spring fully extends and the nut contacts the bracket, when the bracket moves upward, it will synchronously drive the pressing plate to move upward together, and then disengage from the fixture backplane.

[0080] In the present utility model, in the spring compression state, since the pressing plate abuts against the top surface of the fixture backplane, therefore, the bottom surface of the pressing plate and the bottom surface of the scraping plate are basically flush. If there is a concave cavity on the fixture backplane and the label is attached to the concave cavity, then the bottom surface of the scraping plate is below the bottom surface of the pressing plate. If there is a convex part on the fixture backplane and the label is attached to the convex part, then the bottom surface of the pressing plate is above the bottom surface of the scraping plate. If the label is flush with the top surface of the fixture backplane, then in the spring compression state, the bottom surface of the scraping plate and the bottom surface of the pressing plate are in the same plane.

[0081] See Figures 1 to 3 As shown, the driving device includes a first driving mechanism 61 and a vertical driving mechanism 62. The vertical driving mechanism 62 is horizontally slidably installed on the frame 1 via a vertical plate 63. The first driving mechanism 61 is configured to drive the vertical plate 63 and the vertical driving mechanism to move to a first position or a second position;

[0082] The bracket 2 is connected to the vertical driving mechanism 62. The vertical driving mechanism 62 is configured to drive the bracket 2 and the label tearing assembly 3 to move up and down.

[0083] In this embodiment, the first driving mechanism can be a cylinder, which drives the vertical plate, the vertical driving mechanism, and the label tearing device to move along the frame to the first position or the second position. The first driving mechanism can also adopt a combination of a motor and a lead screw. The motor drives the lead screw to rotate. While the vertical plate is slidably connected to the frame, the vertical plate is also screwed to the lead screw. When the motor drives the lead screw to rotate, it drives the vertical plate to slide along the frame. The vertical driving mechanism adopts a vertical cylinder or a combination of a vertical motor and a vertical lead screw. In this embodiment, a vertical cylinder is directly adopted. The vertical cylinder is installed on the vertical plate, and the output shaft of the vertical cylinder is connected to the bracket. By the extension and retraction of the output shaft of the vertical cylinder, the bracket is driven to move up and down, realizing the vertical movement of the scraper.
