Description

Technical Field

[0001] The present invention belongs to the technical field of optical accessory production, and particularly relates to a method for sorting spacers. Background Art

[0002] During the process of assembling a camera, spacers are used to separate two adjacent lenses to maintain the distance interval between the lenses. The spacers are processed by stamping raw materials through a stamping process. After separating the spacers from the waste material (i.e., circular waste material) in the center of the spacer, the spacers are taken out and bagged.

[0003] Currently, the common processing method is to use a stamping machine to complete the stamping of a batch of spacer raw materials, and then through manual sorting, the spacers are taken out from the waste material and bagged. The above sorting method not only has low efficiency, but also there is a situation where workers accidentally put the waste material into the bag, resulting in the accidental taking of the waste material when extracting and installing the spacers later.

[0037] The following combines the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0038] A spacer sorting method provided by the present invention includes the following steps:

[0039] S100: Start the stamping machine 10 and the spacer sorting device, and use the material receiving mechanism 1 of the spacer sorting device to export the stamping material of the stamping machine 10 to the screening station;

[0040] S200: At the screening station, the controller controls the screening mechanism 2 of the spacer sorting device to screen the material incoming in step S100;

[0041] S300: Import the spacers obtained by screening in step S200 into the packaging station;

[0042] S400: The controller controls the bag - filling mechanism 3 and the bag - taking manipulator 4 to bag the separated spacers.

[0043] The controller coordinates and controls the stamping machine and the spacer sorting device to cooperate to complete the automatic discharging, screening and packaging of the spacers.

[0044] A spacer sorting device applied in the embodiments of the present invention, such as Figure 2As shown in the figure, it includes a material receiving mechanism 1, a material screening mechanism 2, a bagging mechanism 3 and a bag taking manipulator 4. The material receiving mechanism 1 and the material screening mechanism 2 are both arranged on a frame 5, and the bagging mechanism 3 and the bag taking manipulator 4 are arranged on the side of the frame. A cabinet is provided below the frame 5, and a control panel 6 is provided on the top. A controller is placed in the cabinet, and a touch screen 7 electrically connected to the controller is provided on the control panel 6. The material receiving mechanism 1, the material screening mechanism 2, the bagging mechanism 3 and the bag taking manipulator 4 are all controlled by the controller. The material receiving mechanism 1 has a raw material input end and a raw material output end. The raw material output end of the material receiving mechanism 1 is directly above the material screening mechanism 2. The material screening mechanism 2 has a spacer output end and a waste output end. The spacer output end of the material screening mechanism 2 is directly above the bagging mechanism 3. The bag taking manipulator 4 is located on the periphery of the bagging mechanism 3. When the above-mentioned material screening and bagging machine works, the material receiving mechanism 1 receives the raw materials after being stamped by a punching machine and conveys them to the material screening mechanism 2. The material screening mechanism 2 separates the spacers and waste in the raw materials, conveys the spacers to the bagging mechanism 3 through the spacer output end, and outputs the waste through the waste output end. The bag taking manipulator 4 conveys the packaging bags to the bagging mechanism 3, and the bagging mechanism 3 opens the packaging bags and bags the spacers.

[0045] In another embodiment of the present invention, as Figure 3 shown, a box body 8 for installing the bagging mechanism 3 and the bag taking manipulator 4 is provided on the side of the frame. A tray 80 for placing packaging bags is provided at the bottom of the box body 8. A control cabinet 9 is provided on the side of the punching machine 10, and the control cabinet 9 can be linked with the touch screen 7.

[0046] In a specific embodiment of the present invention, as Figure 5 shown, the material receiving mechanism 1 includes a material receiving channel 11, a material receiving seat 12, a material receiving vibration device 13, a material receiving spring 14 and a material receiving support 15. The material receiving channel 11 is arranged on the material receiving seat 12. The material receiving vibration device 13 is connected to the material receiving seat 12. The upper end of the material receiving spring 14 is connected to the material receiving seat 12, and the lower end of the material receiving spring 14 is connected to the material receiving support 15. The material receiving channel 11 is used to receive raw materials. The material receiving vibration device 13 (vibration motor) drives the raw materials to move forward in the material receiving channel 11 through vibration. During this process, the material receiving spring 14 provides a vibration space.

[0047] During specific production, an input port and an output port are respectively provided at both ends of the material receiving channel 11. The input port is higher than the output port. The input port serves as the raw material input end of the material receiving mechanism 1, and the output port serves as the raw material output end of the material receiving mechanism 1. The material receiving channel 11 trends obliquely downward from the punching machine to the material screening mechanism 2, which is beneficial to the movement of raw materials.

[0048] In addition, the material receiving mechanism 1 further includes a first material blocking device 16 and a second material blocking device 17. The first material blocking device 16 is arranged in the middle of the material receiving channel 11, and the second material blocking device 17 is arranged at the output port of the material receiving channel 11. Among them, the middle of the material receiving channel 11 refers to the position between the input port and the output port. Setting the first material blocking device 16 and the second material blocking device 17 can realize the function of feeding in batches and ensure that the number of spacer rings loaded each time is the same.

[0049] The structures and working principles of the above-mentioned first material blocking device 16 and second material blocking device 17 are similar. Taking the first material blocking device 16 as an example, it includes a material blocking cylinder 161, a material blocking cover 162, a material blocking rotating shaft 163 and a material blocking sliding shaft 164. Both side plates of the material blocking cover 162 have shaft holes. The two ends of the material blocking rotating shaft 163 are respectively fixed to the two shaft holes. A strip hole 165 is also provided on one side plate of the material blocking cover 162. The material blocking sliding shaft 164 passes through the strip hole 165. The piston rod of the material blocking cylinder 161 is fixed to the material blocking sliding shaft 163. The material blocking rotating shaft is rotatably arranged in the material receiving channel 11. When the piston rod of the material blocking cylinder pushes the material blocking sliding shaft to move in the strip hole, the material blocking cover will rotate around the material blocking rotating shaft, thereby realizing the functions of opening and closing.

[0050] As a preferred mechanism, as Figure 6 shown, the material screening mechanism 2 includes a material screening box 21, a material screening vibration device 22, a material screening spring 23 and a material screening support 24. The material screening box 21 has a material screening hole 211 and a discharge port 212. The material screening hole 211 is located on the bottom surface of the material screening box 21, and the discharge port 212 is located on the side surface of the material screening box 21. The material screening vibration device 22 is connected to the material screening box 21; the material screening spring 23 is sleeved on the guide rod, and the upper end of the material screening spring 23 contacts the material screening box 21, and the lower end of the material screening spring 23 contacts the material screening support 24. The material screening vibration device 22 (vibration motor) drives the spacer rings to move to the discharge port 212 in the material screening box 21 through vibration. After sufficient vibration, all the waste materials fall from the material screening holes 211. During this process, the material screening spring 23 provides a vibration space.

[0051] Among them, the diameter of the material screening hole 211 is larger than the diameter of the waste material and smaller than the diameter of the spacer ring. In this embodiment, there are multiple material screening holes 211, and all the material screening holes 211 are evenly distributed on the bottom surface of the material screening box 21 and occupy more than 60% of the area to ensure the screening efficiency.

[0052] During specific production, the material screening mechanism 2 further includes a waste material box 20. The material screening support 24 also has a material dropping hole 241. The material dropping hole 241 is located directly below the material screening hole 211, and the waste material box 20 is located directly below the material dropping hole 241. The waste materials falling from the material screening holes 211 pass through the material dropping hole 241 to reach the waste material box 20, thereby completing the collection of the waste materials.

[0053] More specifically, the screening mechanism 2 further includes two waste funnels 26. One waste funnel 26 is located between the screening holes 211 and the blanking holes 241, and the other waste funnel 26 is located between the blanking holes 241 and the waste box 20. By providing two waste funnels 26, it is possible to prevent the waste from scattering to other positions and ensure the effect of centralized collection.

[0054] To further optimize the above solution, the screening mechanism 2 further includes a screening base 27 and a lifting device 28. The screening support 24 has a screening rotating shaft 242. The screening rotating shaft 242 and the screening base 27 are oppositely arranged at both ends of the screening support 24, and the screening support 24 can form a rotational connection with the screening rotating shaft 242 (that is, the two can rotate relative to each other, the same below). The screening rotating shaft 242 is fixed on the tabletop 25, and the screening support 24 can be placed parallel to the tabletop 25; the movable end of the lifting device 28 is connected to the screening base 27, and the screening rotating shaft 242 is closer to the discharge port 212 of the screening box 21 than the lifting device 28. When all the waste has completely fallen, the lifting device 28 can drive the screening support 24 to rotate upward around the screening rotating shaft 242. At this time, the end of the screening box 21 far from the discharge port 212 is lifted upward, and the spacer can more easily reach the end where the discharge port 212 is located.

[0055] During specific manufacturing, the lifting device 28 includes a lifting cylinder and a lifting block. The piston rod of the lifting cylinder is arranged in the vertical direction and is fixed to the lifting block, and the lifting block is fixed to the screening support 24.

[0056] To further optimize the above solution, the screening mechanism 2 further includes a discharge channel 30, and the discharge channel 30 is located directly below the discharge port 212. Providing the discharge channel 30 can prevent the spacers from scattering to other positions and ensure that the spacers accurately reach the packaging bags. At the same time, the screening mechanism 2 further includes a screening baffle device 29, and the screening baffle device 29 is arranged at the discharge port 212. Providing the screening baffle device 29 can cooperate with the baffle device of the material receiving mechanism 1 to achieve the function of distributing and bagging.

[0057] Such as Figure 7As shown, the bagging mechanism 3 includes a plurality of suction heads 31, two movable plates 32, an opening and closing device 33 for driving the two movable plates 32 to move away from and close to each other, a horizontal slide 34 for driving the two movable plates 32 to move horizontally, and a vertical slide 35 for driving the two movable plates 32 to move vertically. Each movable plate 32 is provided with at least one suction head 31, and the suction heads 31 of the two movable plates 32 are arranged opposite to each other. The opening and closing device 33 is connected to the two movable plates 32, the horizontal slide 34 is connected to the opening and closing device 33, and the vertical slide 35 is connected to the horizontal slide 34. When the bagging mechanism 3 works, the suction head 31 is used to adsorb the side of the packaging bag. The two movable plates 32 are driven by the opening and closing device 33 to move away from and close to each other to realize the operation of opening and closing the packaging bag. The position of the packaging bag is controlled by the horizontal slide 34 and the vertical slide 35 to ensure that the spacer is accurately loaded.

[0058] In this embodiment, the opening and closing device 33 includes an opening and closing air cylinder and two movable blocks. The opening and closing air cylinder is a two-way air cylinder. The two piston rods of the opening and closing air cylinder are arranged horizontally and are respectively fixed to the two movable blocks. The two movable blocks are respectively fixed to the two movable plates 32. The horizontal slide 34 includes a horizontal air cylinder and a horizontal bracket. The piston rod of the horizontal air cylinder is arranged horizontally and is fixed to the horizontal bracket. The horizontal bracket is fixed to the cylinder block of the opening and closing air cylinder. The vertical slide 35 includes a vertical air cylinder and a vertical bracket. The piston rod of the vertical air cylinder is arranged vertically and is fixed to the vertical bracket. The vertical bracket is fixed to the cylinder block of the horizontal air cylinder.

[0059] As Figure 8 shown, the bag-taking manipulator 4 includes a bag-taking chuck 41, a bag-taking toggle 42 for driving the bag-taking chuck 41 to flip 90° and move, and a bag-taking bracket 43. The bag-taking toggle 42 is connected to the bag-taking chuck 41, and the bag-taking toggle 42 is arranged on the bag-taking bracket 43. When the bag-taking manipulator 4 works, the horizontally placed packaging bag is clamped by the bag-taking chuck 41. The bag-taking chuck 41 is flipped 90° and moved to the position of the bagging mechanism 3 by the bag-taking toggle 42. After the suction head 31 of the bagging mechanism 3 adsorbs the packaging bag, the bag-taking chuck 41 releases the packaging bag. Among them, the bag-taking chuck 41 includes a bag-taking air cylinder and two clamping pieces. The piston rod of the bag-taking air cylinder is fixed to one of the clamping pieces, and the other clamping piece and the cylinder block of the bag-taking air cylinder are arranged on the bag-taking toggle 42. By the bag-taking air cylinder, one clamping piece can be driven to move away from and close to the other clamping piece, so as to complete the release and clamping operations of the packaging bag.

[0060] During specific manufacturing, the bag-taking toggle 42 includes a toggle cylinder 421, a V-shaped plate 422, a linkage rod 423, and a swing arm 424. The piston rod of the toggle cylinder 421 is fixed to one arm of the V-shaped plate 422, and the linkage rod 423 is fixed to the other arm of the V-shaped plate 422. The linkage rod 423 passes through the middle of the swing arm 424. The bag-taking bracket 43 has a first support shaft 431 and a second support shaft 432. The middle of the V-shaped plate 422 is rotatably connected to the first support shaft 431, and the upper end of the swing arm 424 is rotatably connected to the second support shaft 432. Herein, the middle of the V-shaped plate 422 refers to the position between the two arms, and the middle of the swing arm 424 refers to the position between its upper end and lower end. When the piston rod of the toggle cylinder 421 extends, it can push one arm of the V-shaped plate 422 to rise in the direction of arrow S1. The other arm of the V-shaped plate 422 rotates around the first support shaft 431 in the direction of arrow S2, and under the action of the linkage rod 423, the swing arm 424 rotates around the second support shaft 432 in the direction of arrow S3, thereby realizing the flipping and moving operations of the bag-taking chuck 41.

[0061] In addition, rollers with brakes are installed at the bottom of the frame 5 and the box body 8, which is convenient to move to any working location according to production needs. Cabinets can also be installed inside and on the side of the box body 8 to accommodate maintenance tools or other items, making it more convenient to use.

[0062] During specific manufacturing, as Figure 2 shown, a controller is installed inside the control cabinet, and a touch screen is set on the top. The controller adopts a PLC controller, and the touch screen is equipped with a processor. The processor sends instructions to the controller to control the spacer sorting device to perform spacer sorting operations. At the same time, the spacer sorting device feeds back information to the touch screen through the controller. Through the touch screen, it is convenient to quickly switch the formula according to different spacer specifications and realize the quick sorting operation of spacers, as Figure 1 shown. The functions of each component are as follows:

[0063] 1. The PLC controller is used to receive the parameters / feedback information input by the touch screen, and through I / O communication, it controls the material receiving mechanism, the screening mechanism, and the bagging mechanism to complete the operations of automatic discharging, separation, and bagging, thereby realizing the overall operation process of automatic discharging and bagging of spacers.

[0064] 2. The touch screen is used to control the actions of each cylinder in the spacer sorting device, the start and stop of the vibration motors, alarms, set the connection time between mechanisms, and the switching between the punching machine and the spacer sorting device, etc.

[0065] The control flow of a specific embodiment of the present invention is as follows:

[0066] Step 1: Start the spacer sorting device, and turn on the vibration motor at the bottom of the material receiving channel and the vibration motor at the top of the screening box;

[0067] Step 2: Open the incoming material door at the input port of the material receiving channel. At this time, the outgoing material door at the output port of the material receiving channel is closed.

[0068] Step 3: When the punching machine finishes punching the spacer rings, the incoming material door closes and the outgoing material door opens; the material screening mechanism starts screening. Note that the prerequisite is that the tilting material blocking cylinder of the first material blocking device is in its original position to ensure the smoothness of the material receiving channel.

[0069] Step 4: When the time delay for closing the outgoing material door of the material receiving channel expires, the outgoing material door of the material receiving channel closes and the incoming material door opens, and the punching machine is started.

[0070] Step 5: When the time for the material screening of the material screening mechanism arrives, the material blocking cylinder rises to close the material receiving channel, the vibration motors at the material receiving channel and the screening box 2 are both turned off, the material door at the discharge port of the bagging mechanism opens, and the bag-taking manipulator starts bagging.

[0071] When the shutdown time of the vibration motor at the bottom of the material receiving channel arrives, this vibration motor is turned on to continue receiving materials.

[0072] Step 6: When the discharge of the bagging mechanism is not sufficient to fill a bag, the vibration motors of the material receiving channel and the screening box are turned on again until a bag is filled with spacer rings.

[0073] Step 7: After the discharge is completed, the material door of the bagging mechanism closes, the material blocking cylinder descends to open the material receiving passage, and returns to Step 2.

[0074] Repeat the above Steps 2 - 7 until the production volume of spacer rings that meets the production requirements is achieved.

[0075] In summary, the present invention has the advantages of a compact structure, high automation degree, and high sorting accuracy. The automated equipment is used to complete the sorting operation of the spacer rings, with high working efficiency. The staff only needs to replace the material bag under the system prompt to complete the entire automated process of automatic discharging, separating, and bagging of the spacer rings. The operation is easy and fast, with low labor intensity, and it avoids the situation of material mixing caused by manual operation.

[0076] Many specific details have been set forth in the above description to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed above.
