Description

Technical Field

[0001] The utility model relates to the technical field of photo frame processing equipment, in particular to a photo frame production and transmission mechanism. Background Art

[0002] As a common home decoration, photo frames are not only used to display and protect photos, but also to increase the beauty of the interior. There are slight differences in the structure of the front and back sides of photo frames. For example, a bracket often needs to be installed on the back of the photo frame, so the photo frame needs to be flanged when it is produced.

[0003] Traditional photo frame flanging operations usually rely on robotic arms to complete. The robotic arm grips the edge of the photo frame, lifts it from the workbench, flips it 180 degrees, and then puts it back on the workbench or conveyor belt. Although this operation method is automated, it has the following problems:

[0004] There is a time interval when the robot arm performs the flipping operation, which will affect the transmission efficiency of the photo frame;

[0005] When clamping a larger photo frame, the stability of the robot arm will be affected due to the increase in weight and size, which may easily cause the photo frame to shake or even fall during the flipping process, causing damage;

[0006] Since the clamping force of the robotic arm is difficult to control, excessive force may cause the edge of the photo frame to deform or the glass panel to break, while too little force cannot guarantee the stability of the photo frame during the flipping process.

[0007] Therefore, we propose a photo frame production conveying mechanism to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0027] The present application provides a photo frame production and conveying mechanism, which is mainly used to solve the problem that there is a time interval when a mechanical arm performs a flipping operation in the prior art, which affects the transmission efficiency of the photo frame. When clamping a photo frame with a larger specification, the stability of the mechanical arm will be affected due to the increase in weight and size, which may easily cause the photo frame to shake or even fall during the flipping process, thereby causing damage. Since the clamping force of the mechanical arm is difficult to control, excessive force may cause deformation of the edge of the photo frame or cracking of the glass panel, while too small a force cannot ensure the stability of the photo frame during the flipping process. The following technical solutions are provided, which will be combined with Figure 1-Figure 2 Make a detailed description:

[0028] A photo frame production and conveying mechanism, comprising:

[0029] A conveyor belt 1, with mounting boxes 2 fixedly provided on both sides of the feed end of the conveyor belt 1;

[0030] The guide rail 3 is fixed on one side of the installation box 2. The guide rail 3 is in a semicircular ring shape. A rectangular notch 301 is configured in the middle of one side of the guide rail 3 close to the installation box 2. The rectangular notch 301 allows the photo frame to pass through. Bar holes 302 are symmetrically configured on both sides of the middle of the guide rail 3. Extension plates 303 are fixed on both sides of one end of the guide rail 3 away from the installation box 2. The extension plates 303 are arc-shaped.

[0031] The material guide trough 4 is rotatably connected between the ends of the two extension plates 303 through a rotating shaft. Connecting rods 5 are fixedly arranged on both sides of one end of the material guide trough 4 close to the guide rail 3. The other end of the connecting rod 5 slides through the strip hole 302.

[0032] The locking piece 6 is arranged at the end of the connecting rod 5 , and is used to fix the connecting rod 5 .

[0033] Workflow Description

[0034] Preparation stage: by changing the position of the connecting rod 5, the guide trough 4 is adjusted to a suitable inclination, and the connecting rod 5 is locked by the locking member 6 to maintain the stability of the guide trough 4 and prevent shaking during the flipping process;

[0035] Flipping process: the photo frame enters the guide trough 4 through other conveying devices (not shown in the figure). Since the guide trough 4 is inclined, the photo frame slides down along the guide trough 4 under the action of its own gravity. When the bottom end of the photo frame touches the inner wall of the semicircular guide rail 3, the photo frame starts to flip. When the upper end of the photo frame leaves the guide trough 4, the photo frame slides down along the guide rail 3 to the conveyor belt 1 in the opposite direction. After that, the photo frame enters the next step in the opposite direction.

[0036] Speed ​​control: By adjusting the position of the connecting rod 5, the inclination of the guide trough 4 can be changed, thereby controlling the speed at which the photo frame slides down to meet the needs of different production lines.

[0037] The photo frame production and conveying mechanism utilizes a combination of gravity and mechanical structure to realize automatic flipping of the photo frame. The inclined design of the guide trough 4 and the semicircular ring structure of the guide rail 3 work together to enable the photo frame to naturally flip during the sliding process. The automated flanging process reduces the time interval of the robot arm operation and improves production efficiency. In addition, the stability of the flipping process is ensured by the special design of the guide rail 3, reducing the risk of damage to the photo frame. By adjusting the inclination of the guide trough 4, the conveying speed of the photo frame can be controlled, thereby increasing the stability and reliability of production.

[0038] like Figure 1 As shown, in some embodiments, the locking member 6 includes a limit plate 601 fixedly mounted on the end of the connecting rod 5, a clamping plate 602 is slidably sleeved on the surface of the connecting rod 5, a spring 603 is connected between the limit plate 601 and the clamping plate 602, and the spring 603 is sleeved on the surface of the connecting rod 5, a latch 604 is fixedly mounted on the middle of one side of the clamping plate 602 close to the guide rail 3, and slots 304 are configured at equal intervals in the middle of the back of the guide rail 3, and the slots 304 are adapted to the latch 604. More specifically, when the angle of the guide trough 4 is adjusted, The staff can first press the pressure plate to compress the spring 603. At this time, the pin 604 disengages from the slot 304, and the staff can easily rotate the connecting rod 5 to change the inclination angle of the material guide trough 4. After adjusting the inclination angle of the feed trough, the pressure plate can be released. Under the elastic force of the spring 603, the pin 604 enters the corresponding slot 304 again, thereby preventing the connecting rod 5 from moving in the bar hole 302, and then locking the material guide trough 4 at the specified inclination angle.

[0039] like Figure 2As shown, in some embodiments, a baffle plate 7 is further included, which is fixed at one end of the mounting box 2 away from the guide rail 3. More specifically, the main function of the baffle plate 7 is to serve as a limiting device for the photo frame to prevent the photo frame from continuing to slide off the conveyor belt 1 due to inertia after being flipped.

[0040] like Figure 2 As shown, in some embodiments, the inner side of the baffle plate 7 is provided with a first buffer pad 8, and the inner side of the guide rail 3 is provided with a second buffer pad 9 between the strip holes 302. The first buffer pad 8 and the second buffer pad 9 are both elastic rubber pads. More specifically, the first buffer pad 8 is fixed to the inner side of the baffle plate 7, just at the position where the photo frame first contacts after sliding down the guide rail 3. Its main function is to absorb the impact force generated by the photo frame during the sliding process and reduce the damage to the photo frame caused by collision. The second buffer pad 9 is arranged between the strip holes 302 on the inner side of the guide rail 3. During the flipping process, the bottom end of the photo frame will collide with the inner side wall of the guide rail 3, mainly to absorb the impact force generated by the photo frame during the flipping process and reduce the damage to the photo frame caused by collision. The first buffer pad 8 and the second buffer pad 9 are usually made of elastic rubber material, which has good buffering performance and wear resistance, and can effectively absorb impact force and restore to its original state.

[0041] like Figure 1 As shown, in some embodiments, the thickness of the second buffer pad 9 gradually increases from the middle to the sides. More specifically, the second buffer pad 9 is thicker on both sides and thinner in the middle, forming a natural limiting structure, which ensures that the photo frame is always limited to the middle area of ​​the second buffer pad 9 during the sliding process and will not deviate from the track. Through this limiting effect, it can be ensured that the photo frame always remains stable during the sliding process and will not deviate from the predetermined position.

[0042] like Figure 2 As shown, in some embodiments, the opposite side of the two mounting boxes 2 is an open structure, and the position near the opening inside the mounting box 2 is connected to the roller 10 by rotating the shaft at equal intervals. More specifically, after the photo frame falls onto the conveyor belt 1, the two sides of the photo frame are in sliding contact with the roller 10, which can reduce friction and improve transmission efficiency.

[0043] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
