[0028] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0029] Refer to Figures 1-7, the present utility model provides a lens tray feeding chamber, which includes a turntable 201, a material pressing component, an opening cylinder 208 and a material ejecting component. In this application, feeding refers to feeding (loading) the locking device. Relative to this structure, it is discharging. The structures of each component will be described in detail below.

[0030] The turntable 201 serves as a support and installation carrier for installing other components. The turntable 201 is disc-shaped, horizontally arranged, and can achieve horizontal rotation. A driving motor 202 is provided at the lower end of the turntable 201. The driving motor 202 is vertically arranged, its output shaft is upward, and it is connected to the turntable 201 to drive the turntable 201 to achieve horizontal rotation. A feeding station is provided on the rotation path of the turntable 201 for feeding the locking device, that is, tray feeding. At least two chambers 2036 are circumferentially distributed on the top surface of the turntable 201. In this embodiment, four are circumferentially distributed. One of them is at the feeding station for feeding, and the other chambers are in a state of waiting to be taken. A tray cavity is formed in the chamber 2036 for stacking and placing trays. In this embodiment, the cross-section of the tray cavity is the same as the shape of the tray, both are rectangular, and the upper and lower ends of the tray cavity are open (opened). The lower open end is used as the discharging end. At the same time, a blanking port 2010 corresponding to the tray cavity one by one is opened on the turntable 201. The blanking port 2010 is coaxial with the tray cavity, that is, the blanking port 2010 is located directly below the tray cavity.

[0031] The material blocking component is arranged at the blanking port 2010 and is used to control the opening or closing of the blanking port 2010, thereby realizing the connection or blockage between the material tray cavity and the blanking port 2010. In this embodiment, it is located between the discharge end at the lower end of the material tray cavity and the blanking port 2010. Specifically, the material blocking component includes material blocking plates 2032 symmetrically arranged on both sides of the blanking port 2010. The material blocking plates 2032 are horizontally slidably matched on both sides of the blanking port 2010. The sliding directions of the two material blocking plates on the same blanking port are parallel, and they can move closer to or away from each other. Specifically, horizontal slide rails 2031 are symmetrically arranged on both sides of the blanking port 2010. Sliders are horizontally slidably matched on the horizontal slide rails 2031, and the material blocking plates are fixed to the sliders, thereby enabling them to slide towards each other (move closer) or away from each other (move away); on the inner side of the material blocking plate 2032, there is a material blocking portion 2032a. The material blocking portion 2032a can extend to directly below the material tray cavity as the material blocking plate moves and can contact the bottom of the material tray at the lowermost end of the material tray cavity, thereby realizing material blocking. At this time, the material tray in the material tray cavity cannot fall; at the same time, a first elastic member 2035 is arranged between the two material blocking plates 2032. The first elastic member 2035 makes the material blocking portions (material blocking plates) tend to move closer to each other, that is, the first elastic member makes the material blocking component tend to close the blanking port. The first elastic member can also be arranged on the turntable; on the material blocking plate, there is a pushing portion 2034 for enabling the opening by the opening cylinder. The opening cylinder 208 is vertically arranged below the turntable 201. At the same time, it is located at the feeding station. The output shaft of the opening cylinder 208 is arranged upward. A push block 2081 is arranged on its output shaft. The push block 2081 can contact the pushing portion 2034, thereby pushing the material blocking plate to move outwards, thereby realizing the opening of the blanking port. At this time, the lower end of the material tray cavity is connected to the blanking port, and the discharging of the material tray can be realized; a hole 2011 is opened on the turntable, and it can accommodate the push block to pass through, thereby realizing the driving of the material blocking plate; the above-mentioned pushing portion 2034 can be an inclined guide block or a guide wheel. At the same time, inclined guide surfaces are symmetrically arranged on the push block 2081. The inclined guide surfaces can correspond to the inclined guide block or the guide wheel, and it can push the inclined guide block or the guide wheel to move outwards through its upward movement; in this embodiment, a connecting rod 2033 is fixed to the end of the material blocking plate 2032. The connecting rod 2033 is horizontally arranged, and its length direction is parallel to the sliding direction of the material blocking plate. The pushing portion is a guide wheel and is fixed to the end of the connecting rod 2033. By arranging the above-mentioned connecting rod, the distance between the two pushing portions (inclined guide block or guide wheel) can be reduced, thereby reducing the volume of the push block. In this embodiment, the push block is an isosceles triangle structure, and two inclined guide surfaces are formed on its two sides. When the push block moves upward, it pushes the guide wheel to move outwards, thereby moving the material blocking block outwards and realizing the opening of the blanking port; in this embodiment, the opening cylinder 208 is fixed to the side wall of the driving motor 202.

[0032] In order to control the movement stroke of the material pressing plate, in this embodiment, a first limit block 2037 is provided on the side wall of the chamber 2036. The first limit block is arranged on the rear side wall of the chamber 2036. At the same time, a second limit block 2038 is provided on the material pressing plate 2032. A limit bolt 2039 is threadedly connected to the second limit block 2038. The axis of the limit bolt 2039 is parallel to the sliding direction of the material pressing plate 2032. The end of the limit bolt faces the first limit block, and this end can contact the first limit block, thereby realizing the limitation of the material pressing plate. By adjusting the limit bolt, the distance between the first limit block and the second limit block can be adjusted, and then the distance between the two material pressing plates can be adjusted, so as to realize different extension amounts of the material pressing part in the blanking port.

[0033] In this application, the chamber includes a back plate and fixed side plates and moving side plates respectively arranged on both sides of the back plate. The moving side plate is rotatably installed on the back plate, and its rotation axis is perpendicular to the horizontal plane. A material tray cavity with openings at the front end and the upper and lower ends is formed between the back plate and the two side plates (fixed side plate, moving side plate). At the same time, a second elastic member is provided on the back plate or the turntable. The second elastic member has a tendency for the moving side plate to move closer to the material tray cavity, thereby forming the material tray cavity. When loading materials, the moving side plate is opened outward. After loading, the moving side plate returns to its original position under the action of the elastic force to complete the loading; the front end of the fixed side plate or the moving side plate is bent 90 degrees toward the side of the material tray cavity to form a material tray limiting part to limit the internal material tray, and at the same time, a strip-shaped groove is formed for the sensor to monitor the number of internal material trays to avoid idling.

[0034] In order to ensure the stability and reliability of the feeding, in this embodiment, a top plate 205 is fixed on the turntable 201. The top plate is fixed on the turntable through a plurality of columns. The top plate is horizontally arranged and is located above the chamber 2036. Guide rods 207 are vertically slidably equipped on the top plate 205. There are at least two guide rods 207. A pressure plate 206 is fixed at the lower end of the guide rods 207. The pressure plate 206 is horizontally arranged and is coaxial with the material tray cavity, and can contact the material tray at the top in the material tray cavity, thereby realizing the pressing of the material.

[0035] In order to facilitate the feeding of the material tray, a seat body is fixed on the pressure plate 206. A locking bolt 2061 is threadedly connected to the seat body. The locking bolt 2061 is horizontally arranged, and its end faces one end of the top plate. There is a gap between the locking bolt and the pressure plate 206, and this gap forms a locking area, and the height of the locking area is greater than or equal to the thickness of the top plate 205. When feeding is required, the pressure plate is moved to the uppermost position. At this time, the locking bolt is located above the top plate (not in contact). The locking bolt is screwed, so that the end of the locking bolt extends horizontally inward and is located inside the edge of the top plate. At this time, when the pressure plate is released, the locking bolt can contact the top plate to limit the downward movement of the pressure plate, thereby facilitating the discharging of the material.

[0036] Meanwhile, a feeding manipulator is arranged at the feeding station, which is located below the turntable and is used to move the tray at the lowest end of the tray cavity at the feeding station to the locking device at this station for locking operation.

[0037] The lens tray feeding chamber of the present utility model adopts a rotary vertical chamber structure, which occupies a small space and has a large placement capacity. It can realize rotary non-stop feeding and feeding, with high working efficiency. A material blocking component is set to realize the opening and closing of the blanking port and the individual feeding of the locking device. The vertical cylinder push block structure is compact and has a small installation space, which can realize the rapid and effective control of the material blocking component to achieve opening or closing. A connecting rod structure is set to reduce the distance between the two pushing parts, which is beneficial to the miniaturization of the push block structure and improves the structural compactness. The rotating side plate structure is set to facilitate the opening of the tray cavity and the placement of the tray, and can realize automatic closing and resetting. It is compact in structure, easy to operate and convenient for feeding. A pressing plate is set to generate a certain downward pressure on the tray in the tray cavity, ensuring the smooth falling of the bottom tray and avoiding the occurrence of jamming phenomena, and improving the reliability and stability of operation.
