Description

Technical Field

[0001] The utility model relates to the technical field of transportation, and particularly relates to a double-feed circulation device for a polarizer detection device. Background Technique

[0002] A polarizer, also known as a polarization film, is a special optical material mainly used to control the polarization state of light. It allows light in a certain direction to pass through while blocking light in another direction, thereby achieving polarization filtering of light. Polarizer products come in many sizes. Generally, small-sized polarizers are formed by cutting large polarizers. To improve production efficiency and meet the processing requirements of various sizes, large polarizers may be cut into various sizes simultaneously. Each size of polarizer needs to be subjected to Mark detection, and then the qualified products and defective products are sorted. Currently, the sizes of polarizers range from 9.5 inches to 27 inches. Polarizers of the same size are stacked on a polarizer carrier and transported together. When performing Mark detection, the polarizer carrier is sent into the polarizer detection device, and the polarizers need to enter the detection channel one by one separately.

[0003] Our company has applied for Chinese Patent CN213010731U, which discloses a fully automatic feeding device for polarizers docking with AGV from 12 to 43 inches. This device can continuously feed the turnover fixture with polarizers into the detection device, where the upper conveyor line and the lower conveyor line are respectively responsible for the front and back transportation of the turnover fixture. However, the operation rhythm of the device is relatively slow, which will restrict the acceleration of the detection speed.

[0004] Therefore, it is necessary to improve the feeding structure to solve the above problems. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a double-feed circulation device for a polarizer detection device, which can realize the rapid circulation feeding of various polarizers.

[0006] The utility model realizes the above purpose through the following technical scheme: A double-feed circulation device for a polarizer detection device includes a frame, two feeding circulation units, and a plurality of feeding carriers. Two feeding areas are arranged side by side along the Y direction on the frame. The two feeding circulation units are respectively located in the two feeding areas. The feeding circulation unit drives the feeding carrier to move circularly in the XZ plane. The X direction and the Y direction are both in the horizontal plane and perpendicular to each other, and the Z direction is the vertical direction.

[0007] Specifically, the feeding circulation unit includes a first lifting mechanism, a second lifting mechanism, two upper translation mechanisms, and two lower translation mechanisms. The feeding area is divided into a middle lifting area and translation areas on both Y-direction sides of the lifting area. The first lifting mechanism and the second lifting mechanism are located at both ends in the X direction of the lifting area, the two upper translation mechanisms are respectively arranged at the upper parts of the two translation areas, and the two lower translation mechanisms are respectively arranged at both Y-direction sides of the lower part of the lifting area.

[0008] The upper translation mechanism includes an upper X-direction driving module, a plurality of side-shifting modules, and an upper sliding table. The side-shifting modules are fixed to the upper part of the frame and drive the upper X-direction driving module to translate along the Y direction, and the upper X-direction driving module drives the upper sliding table to translate along the X direction.

[0009] The lower translation mechanism includes a lower X-direction driving module and the lower sliding table, and the lower X-direction driving module drives the lower sliding table to translate along the X direction.

[0010] Furthermore, there are two feeding circulation units. Two feeding areas are arranged side by side along the Y direction on the frame, and the two feeding circulation units are respectively located in the two feeding areas.

[0011] Specifically, the feeding carrier includes a bottom plate and several limiting blocks. The limiting blocks are fixed on the upper surface of the bottom plate and enclose a limiting space for the polarizer carrier plate.

[0012] Furthermore, several translation positioning holes are arranged on both Y-direction sides of the bottom plate. Several upper positioning pins matching the translation positioning holes are arranged on the upper sliding table, and several lower positioning pins matching the translation positioning holes are arranged on the lower sliding table.

[0013] Furthermore, several lifting positioning holes are arranged on both X-direction sides of the bottom plate. Both the first lifting mechanism and the second lifting mechanism include a lifter and a lifting table driven by the lifter to lift. Several lifting positioning pins matching the lifting positioning holes are arranged on the lifting table.

[0014] The beneficial effect of the technical solution of the present utility model is:

[0015] This device can not only perform circular feeding on the feeding carrier through two feeding circulation units, but also each feeding circulation unit alternately conveys two feeding carriers, accelerating the feeding rhythm. Description of the Drawings

[0026] The following further elaborates on the present utility model in conjunction with specific embodiments.

[0027] Embodiment:

[0028] As Figure 1 shown, a double - feeding circulation device 1 for a polarizer detection device of the present utility model includes a frame 11, two feeding circulation units 12, and four feeding tools 13. Two feeding areas are arranged side - by - side along the Y direction on the frame 11. The two feeding circulation units 12 are respectively located in the two feeding areas. Each feeding circulation unit 12 drives two feeding tools 13 to circulate in the XZ plane. The X direction and the Y direction are both in the horizontal plane and perpendicular to each other, and the Z direction is the vertical direction.

[0029] In this device, the X direction is the conveying direction of the polarizer 3. The polarizer 3 is placed on the polarizer carrier board 2, and the polarizer carrier board 2 uses the feeding tool 13 as a transfer carrier. The fully - loaded polarizer carrier board 2 enters the feeding area from one end in the X direction, and is sent to the other end in the X direction by the feeding circulation unit 12. Then the polarizers are taken and loaded one by one. The emptied polarizer carrier board 2 is sent back to the feeding position by the feeding circulation unit 12. Not only can the two feeding circulation units 12 perform cyclic feeding on the feeding tools 13, but each feeding circulation unit 12 alternately conveys the two feeding tools 12, accelerating the feeding rhythm.

[0030] As Figure 3As shown in the figure, the feeding carrier 13 includes a bottom plate 131 and a plurality of limiting blocks 132. The limiting blocks 132 are fixed on the upper surface of the bottom plate 131 and enclose a limiting space for the polarizer carrier 2. A plurality of translation positioning holes 1311 are provided on both sides of the bottom plate 131 in the Y direction, and a plurality of lifting positioning holes 1312 are provided on both sides in the X direction.

[0031] During the transfer process, the feeding carrier 13 uses the translation positioning holes 1311 and the lifting positioning holes 1312 for pin shaft positioning. The positioning reference during the X-direction translation is the translation positioning hole 1311, and the positioning reference during the Z-direction lifting is the lifting positioning hole 1312 to ensure the stability of the movement.

[0032] As Figure 2 and Figure 3 As shown in the figure, the feeding cycle unit 12 includes a first lifting mechanism 121a, a second lifting mechanism 121b, two upper translation mechanisms 122 and two lower translation mechanisms 123. The feeding area is divided into a middle lifting area and translation areas on both sides of the lifting area in the Y direction. The first lifting mechanism 13a and the second lifting mechanism 13b are located at both ends of the lifting area in the X direction. Both the first lifting mechanism 13a and the second lifting mechanism 13b include a lifter 1211 and a lifting platform 1212 driven by the lifter 1211 to lift. A plurality of lifting positioning pins (not exposed) matching the lifting positioning holes 1312 are provided on the lifting platform 1212; the two upper translation mechanisms 14 are respectively arranged on the upper parts of the two translation areas, and the two lower translation mechanisms 123 are respectively arranged on both sides of the lower part of the lifting area in the Y direction; the upper translation mechanism 122 includes an upper X-direction driving module 1221, a plurality of side shift modules 1222 and an upper sliding table 1223. The side shift modules 1222 are fixed on the upper part of the frame 11 and drive the upper X-direction driving module 1221 to translate in the Y direction. The upper X-direction driving module 1221 drives the upper sliding table 1223 to translate in the X direction. A plurality of upper positioning pins 12231 matching the translation positioning holes 1311 are provided on the upper sliding table 1223; the lower translation mechanism 123 includes a lower X-direction driving module 1231 and a lower sliding table 1232. The lower X-direction driving module 1231 drives the lower sliding table 1232 to translate in the X direction. A plurality of lower positioning pins (not exposed) matching the translation positioning holes 1311 are provided on the lower sliding table 1232.

[0033] The first lifting mechanism 121a uses the lifting positioning pin to cooperate with the lifting positioning hole 1312 to make the feeding bracket 13 separate from the upper translation mechanism 122. The upper translation mechanism 122 uses the side shift module 1222 to avoid to both sides and leave the lifting area, and then descends to the lower translation mechanism 123, so that the lower positioning pin matches the position of the translation positioning hole 1311. The first lifting mechanism 121a continues to move downward and leaves the translation path of the feeding bracket 13 below; the lower translation mechanism 123 is used to move the feeding bracket 13 from the lifting range of the first lifting mechanism 121a to the lifting range of the second lifting mechanism 121b, so that the lower The positioning pin can match the lifting positioning hole 1312; the second lifting mechanism 121b is used to make the feeding bracket 13 separate from the lower translation mechanism 123, and then rise to the top of the upper translation mechanism 122, and then the side shift module 1222 makes the upper X-direction drive module 1221 move from the translation area along the Y direction into the lifting area, so that the upper positioning pin 12231 is aligned with the translation positioning hole 1311, and then the lifting platform 1212 descends, allowing the feeding bracket 13 to fall on the upper slide 1223; the upper X-direction drive module 1221 drives the upper slide 1223 to move along the X direction, so that the feeding bracket 13 returns to the top of the first lifting mechanism 121a. Therefore, the device can utilize the first lifting mechanism 121a, the second lifting mechanism 121b, the upper translation mechanism 122 and the lower translation mechanism 123 to circulate the feeding bracket 13, and circulate the polarizer carrier 2 through the feeding bracket 13 to achieve the purpose of cyclic feeding, with high working efficiency.

[0034] The working process of the dual-feed circulation device 1 is as follows: the feeding bracket 13 is initially located below one end of the feeding area and is seated on the lower slide 1232, at which time the fully loaded polarizer carrier plate 2 is placed on the feeding bracket 13; the lower translation mechanism 123 translates the feeding bracket 13 to the top of the second lifting mechanism 121b, and the second lifting mechanism 121b lifts the feeding bracket 13 to the highest point, at which time a transfer mechanism will remove the polarizer 3 from the polarizer carrier plate 2 piece by piece until the polarizer carrier plate 2 is vacated. In this process, the upper The translation mechanism 122 will move inward, so that the upper slide 1223 will stop under the feeding bracket 13 in advance, reducing unnecessary pause time, and the second lifting mechanism 121b will descend, so that the feeding bracket 13 will fall on the upper slide 1223, and the upper translation mechanism 122 will return the feeding bracket 13 to the feeding position, and the upper translation mechanism 122 will move to both sides, and then the first lifting mechanism 121a will lower the feeding bracket 13 to the initial position, and the empty polarizer carrier 2 will be replaced with a fully loaded polarizer carrier 2, completing the feeding cycle. Two feeding brackets 13 can be operated alternately in the same feeding circulation unit 12 to make the feeding rhythm faster.

[0035] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the creative concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model.
