Description

Technical Field

[0001] This utility model belongs to the technical field of testing devices, and in particular relates to a printer mounting plate verticality testing device. Background Technology

[0002] With the development of technology, printers have evolved from the initial dot matrix printers to various types such as laser printers and inkjet printers. Regardless of the type of printer, its internal structure requires a high degree of precision, especially the verticality of the mounting plate. If the verticality of the mounting plate does not meet the standard, it may cause the print head to shift, thereby affecting the printing effect and even causing equipment failure.

[0003] Currently, operators typically determine whether the mounting plate is vertical by visual inspection. This method is highly dependent on the operator's experience and skill level, is easily affected by subjective factors, and has low accuracy. Another common method is to manually measure the angle between the mounting plate and the reference surface using a right-angle ruler or protractor. Although this method is more accurate than visual inspection, it still has human error and is cumbersome and time-consuming. Therefore, it is necessary to design a printer mounting plate verticality detection device to address the shortcomings of existing technologies. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a printer mounting plate verticality detection device.

[0005] The technical solution is: a printer mounting plate verticality detection device, comprising a frame and a worktable, wherein the frame is the load-bearing carrier of the device, and the worktable is fixedly mounted on the frame; further comprising: a support plate, fixedly connected to the table surface of the worktable, the support plate being L-shaped; a sliding frame, slidably connected to the support plate via a guide rod; a connecting block, rotatably mounted on the upper part of one side of the sliding frame, the connecting block being square; a laser emitter, mounted on the connecting block, the laser emitter on the connecting block being inclined downwards; and a receiver, mounted on the side of the sliding frame where the laser emitter is located via the square block, the laser emitter and receiver being on the same vertical plane, the receiver... The receiver's receiving port is perpendicular to the worktable surface. The receiver is used to receive laser light emitted by the laser emitter. A slide rod is slidably mounted on the upper part of the sliding frame on the same side as the laser emitter. The slide rod is connected to the connecting block. A spring is located between the slide rod and the sliding frame. It pushes the sliding frame so that the receiver on it is vertically attached to the vertical surface of the printer mounting plate. When the connecting block contacts the vertical surface of the printer mounting plate, it will rotate under the guidance of the slide rod, overcoming the elastic force of the spring. When the connecting block is vertically attached to the vertical surface of the printer mounting plate, the receiver receiving laser light from the laser emitter on the connecting block indicates that the printer mounting plate is vertical. Otherwise, the printer mounting plate is not vertical enough.

[0006] As a further preferred embodiment, a second spring is provided between the guide rod and the support plate. The elastic force of the second spring is greater than that of the first spring. The second spring is in a stretched state and has a tendency to push the sliding frame outward. After the user pulls the limiting sliding frame, the printer to be tested is placed on the workbench. After releasing the sliding frame, under the action of the second spring, the connecting block where the laser emitter is located and the square block where the receiver is located are pressed against the mounting plate of the printer for testing.

[0007] As a further preferred embodiment, a limiting component is also included, which includes a cylinder and a contact plate. The cylinder is fixedly mounted on the worktable by a bracket, and the contact plate is fixed on the telescopic rod of the cylinder. The contact plate contacts and limits the sliding frame. By extending the telescopic rod of the cylinder, the contact plate can be released from the lock on the sliding frame, saving the operation of manually pushing the sliding frame for testing.

[0008] As a further preferred embodiment, a cylinder two is fixedly installed at the bottom of the workbench surface, a sliding groove is opened on the workbench surface, a sliding plate is slidably installed on the sliding groove of the workbench, the sliding plate is connected to the telescopic rod of the cylinder two, and a fixing plate is fixedly installed on the workbench surface corresponding to the sliding plate, the sliding plate and the fixing plate cooperate to limit the printer placed on the workbench.

[0009] As a further preferred embodiment, a bidirectional cylinder is fixedly installed on the sliding plate. Clamping plates are fixedly installed on the bidirectional telescopic rods of the bidirectional cylinder. The clamping plates at both locations are used to clamp the printer from both sides. Together with the sliding plate and the fixed plate, the printer on the worktable is stably limited and locked, preventing the printer from shifting and affecting the vertical detection of its mounting plate.

[0010] As a further preferred embodiment, it also includes rubber blocks. Rubber blocks are provided on the clamping surfaces of the sliding plate and the fixed plate, and rubber blocks are also provided on the clamping surfaces of the clamping plates on both sides. The rubber blocks are used to elastically clamp the printer and improve the stability of the printer when it is positioned on the worktable.

[0011] The present invention has the following advantages: 1. The present invention can achieve high-precision detection of the verticality of the printer mounting plate by means of the cooperation of the laser emitter and receiver. The connecting block is vertically attached to the vertical surface of the printer mounting plate. The printer mounting plate is vertical according to whether the receiver receives the laser signal, thereby eliminating human error and improving the accuracy of detection.

[0012] 2. The sliding frame of this utility model, through the cooperation of the guide rod and the second spring, can automatically reset after the printer to be tested is placed, so that the laser emitter and receiver are tightly attached to the printer mounting plate. With the help of the contact plate to lock the sliding frame, the operation steps are simplified and manual intervention is reduced, thus improving the testing efficiency.

[0013] 3. The worktable of this utility model is equipped with a second cylinder, a sliding plate, a fixed plate, and a bidirectional cylinder. Through the synergistic effect of these components, the printer to be tested can be firmly clamped, preventing the printer from shifting during the testing process and ensuring the reliability of the test.

[0019] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "setting," "installing," "connecting," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0020] A printer mounting plate verticality detection device, such as Figures 1-3As shown, the device includes a frame 1 and a workbench 2. The frame 1 serves as the load-bearing carrier of the device, and the workbench 2 is fixedly mounted on the frame 1. It also includes: a support plate 3, fixedly connected to the surface of the workbench 2, the support plate 3 being L-shaped; a sliding frame 4, slidably connected to the support plate 3 via a guide rod 41; a connecting block 5, rotatably mounted on the upper part of one side of the sliding frame 4, the connecting block 5 being a square block; a laser emitter 6, mounted on the connecting block 5, the laser emitter 6 being tilted downwards; and a receiver 7, mounted on the sliding frame 4 via the square block to the laser emitter 6. On one side, the laser emitter 6 and receiver 7 are on the same vertical plane. The receiving port of receiver 7 is perpendicular to the surface of the worktable 2. Receiver 7 is used to receive the laser emitted by laser emitter 6. Sliding rod 8 is slidably mounted on the upper part of the sliding frame 4 on the same side as laser emitter 6. Sliding rod 8 is connected to connecting block 5. Spring 81 is located between sliding rod 8 and sliding frame 4. It pushes sliding frame 4 so that receiver 7 on it is vertically attached to the vertical surface of printer mounting plate. Connecting block 5, when in contact with the vertical surface of printer mounting plate, will be guided by sliding rod 8. Overcoming the elastic force of spring 81, the connecting block 5 rotates until it is perpendicular to the vertical surface of the printer mounting plate. When the receiver 7 receives the laser from the laser emitter 6 on the connecting block 5, it indicates that the printer mounting plate is vertical; otherwise, the printer mounting plate is not vertical enough. A second spring 9 is provided between the guide rod 41 and the support plate 3. The elastic force of the second spring 9 is greater than that of the first spring 81. The second spring 9 is in a stretched state and has a tendency to push the sliding frame 4 outward. After the user pulls the limiting sliding frame 4, the printer to be tested is placed on the table surface of the worktable 2, and the sliding frame 4 is released. After the moving frame 4 is activated by the action of the second spring 9, the connecting block 5 where the laser emitter 6 is located and the square block where the receiver 7 is located are pressed against the mounting plate of the printer for detection. The limiting component includes a cylinder 10 and a contact plate 11. The cylinder 10 is fixedly installed on the worktable 2 by a bracket. The contact plate 11 is fixed on the telescopic rod of the cylinder 10. The contact plate 11 contacts and limits the sliding frame 4. The extension of the telescopic rod of the cylinder 10 can release the contact plate 11 from the lock on the sliding frame 4, saving the operation of manually pushing the sliding frame 4 for detection.

[0021] like Figure 1 and Figure 4As shown, a second cylinder 12 is fixedly installed at the bottom of the workbench 2. A sliding groove is opened on the workbench 2, and a sliding plate 13 is slidably installed on the sliding groove of the workbench 2. The sliding plate 13 is connected to the telescopic rod of the second cylinder 12. A fixed plate 14 is fixedly installed on the workbench 2 on one side corresponding to the sliding plate 13. The sliding plate 13 and the fixed plate 14 limit the printer placed on the workbench 2. A two-way cylinder 15 is fixedly installed on the sliding plate 13. Clamping plates 16 are fixedly installed on the two-way telescopic rod of the two-way cylinder 15. The clamping plates 16 at both locations are used to clamp the printer from both sides. Together with the sliding plate 13 and the fixed plate 14, the printer on the workbench 2 is stably limited and locked, preventing the printer from shifting and affecting the vertical detection of its mounting plate.

[0022] like Figure 4 As shown, it also includes rubber blocks 17. Rubber blocks 17 are provided on the clamping surfaces of the sliding plate 13 and the fixed plate 14. Rubber blocks 17 are also provided on the clamping surfaces of the clamping plates 16 on both sides. The rubber blocks 17 are used to elastically clamp the printer and improve the stability of the printer on the upper limit of the worktable 2.

[0023] When using this device to perform vertical testing on the printer mounting plate, the printer to be tested is placed on the workbench 2. Then, cylinder 12 drives the sliding plate 13 to move towards the fixed plate 14 until the sliding plate 13 and the fixed plate 14 together clamp the front sides of the printer. During this process, the bidirectional cylinder 15 on the sliding plate 13 extends two clamping plates 16 to hold the printer from the left and right sides, ensuring that the printer does not move during testing. Rubber blocks 17 are covered on the clamping surfaces of the clamping plates 16 and the fixed plate 14 to provide elastic clamping and prevent damage to the printer surface. After the printer is securely clamped, the telescopic rod of cylinder 10 extends, causing the contact plate 11 to disengage from the sliding frame 4. At this time, because the spring 9 between the guide rod 41 and the support plate 3 is in a stretched state, it has a tendency to push the sliding frame 4 outwards. Under the action of spring 29, it will quickly move towards the printer mounting plate. The connecting block 5 where the laser emitter 6 is located and the block where the receiver 7 is located on the sliding bracket 4 will simultaneously press against the printer mounting plate. When the connecting block 5 contacts the vertical surface of the printer mounting plate, the connecting block 5 will rotate under the guidance of the slide rod 8, overcoming the elastic force of spring 181, until the connecting block 5 is completely perpendicular to the vertical surface of the mounting plate. If the printer mounting plate is vertical, the laser emitted by the laser emitter 6 will directly enter the receiving port of the receiver 7. The receiver 7 receives the laser signal, indicating that the printer mounting plate is vertical. If the printer mounting plate is not vertical enough, the connecting block 5 cannot completely fit the vertical surface of the mounting plate, and the laser emitted by the laser emitter 6 cannot accurately enter the receiving port of the receiver 7. The receiver 7 does not receive the laser signal, indicating that there is a verticality deviation of the printer mounting plate.

[0024] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
