The lower end of the material picking and pressing fixture is provided with a material picking chamber, and an air extraction pipe is provided through the material picking and pressing fixture. One end of the air extraction pipe is connected to the material picking chamber, and the other end is connected to an external vacuum device. The material picking and pressing drive can drive the material picking and pressing fixture to move vertically downward so that the lower end surface of the material picking and pressing fixture presses against the cap on the receiving seat, and the cap seals the lower port of the material picking chamber.

[0011] Preferably, the material feeding and pressing assembly further includes:

[0012] A pressure-down adapter block is provided. The upper end of the pressure-down adapter block is connected to the execution end of the material-taking pressure-down drive unit through a pressure-down floating joint.

The air extraction pipe is also provided through the pressure-down adapter block. The air extraction pipe has an air hole for connecting to an external vacuuming device located in the pressure-down adapter block.

[0013] Preferably, the lower end of the pressing adapter block is detachably connected to the upper end of the material-taking pressing fixture.

[0014] Preferably, the gland mounting mechanism further includes:

[0015] Material handling and pressing base;

[0021] Preferably, the gland mounting mechanism further includes:

[0022] A pressure cap translation guide rail is provided along the first direction on the material picking and pressing mounting frame;

[0023] The cap translation guide block is fixedly connected to the material picking and pressing base, and the cap translation guide block and the cap translation guide rail are slidably arranged relative to each other along the first direction.

[0024] Preferably, the receiving assembly includes two receiving seats, and the receiving assembly further includes:

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0046] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0048] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0049] This embodiment provides a cap feeding and assembly device for feeding caps and pressing them onto the upper end of the lens to be assembled. Figures 1-5 As shown, the cap feeding assembly device includes a receiving component 100, a cap mounting mechanism 200, and a cap feeding vibratory feeder 300. The cap feeding vibratory feeder 300 is used to vibrate and feed caps. The receiving component 100 is located at the discharge end 301 of the cap feeding vibratory feeder 300. The receiving component 100 includes a receiving seat 110 capable of accommodating a single cap, which receives the cap fed by the cap feeding vibratory feeder 300. The cap mounting mechanism 200 includes a material-removing and pressing component, which removes the cap from the receiving seat 110 and presses it onto the upper end of the lens to be assembled.

[0050] Furthermore, such as Figures 1-3 as well as Figure 5As shown, the material taking down and pressing assembly includes a material taking down and pressing drive 201 and a material taking down and pressing fixture 210 installed on the execution end of the material taking down and pressing drive 201. The lower end of the material taking down and pressing fixture 210 is provided with a material taking chamber 211. An air extraction pipe is provided through the material taking down and pressing fixture 210. One end of the air extraction pipe is connected to the material taking chamber 211, and the other end is connected to an external vacuuming device. The material taking down and pressing drive 201 can drive the material taking down and pressing fixture 210 to move vertically downward, so that the lower end surface of the material taking down and pressing fixture 210 presses against the pressure cap on the material seat 110, and the pressure cap seals the lower port of the material taking chamber 211.

[0051] Specifically, the cap feeding assembly device provided in this embodiment first feeds caps through a cap feeding vibratory feeder 300. At the discharge end 301 of the cap feeding vibratory feeder 300, a receiving seat 110 receives the discharged caps. A material-taking and pressing drive 201 drives a material-taking and pressing fixture 210 downwards, causing the lower end face of the material-taking and pressing fixture 210 to press against the cap on the receiving seat 110. The cap seals the lower port of the material-taking chamber 211. (The last sentence appears to be incomplete and possibly refers to a vacuum pump.) Driven by the empty equipment, a negative pressure space is formed in the material picking chamber 211. The cap is adsorbed onto the lower end of the material picking and pressing fixture 210. The material picking and pressing drive 201 drives the material picking and pressing fixture 210 and the cap to rise together. When the cap is above the lens to be assembled, the material picking and pressing drive 201 drives the material picking and pressing fixture 210 and the cap to press down together, pressing the cap onto the upper end of the lens to be assembled, thus completing the cap loading and pressing operation. In summary, the cap loading and assembly device provided in this embodiment completes the cap loading and pressing operation sequentially through the material picking and pressing component, realizing the integrated operation of cap loading and pressing, eliminating the need for multiple cap loading and unloading, improving production efficiency and reducing equipment costs.

[0052] For example, such as Figure 1 , Figure 2 and Figure 4 As shown, the discharge channel of the cap feeding vibratory feeder 300 discharges material along a horizontal first direction. A discharge end 301 is provided at the far end of the discharge channel. A receiving groove 111 for accommodating the cap is provided in the receiving seat 110. An inlet 112 is provided on the side of the receiving groove 111 facing the cap feeding vibratory feeder 300. The inlet 112 and the discharge end 301 of the cap feeding vibratory feeder 300 are arranged opposite each other in the first direction, which is the X direction in the figure.

[0053] For example, the receiving assembly 100 includes two receiving seats 110, a receiving base 101, a receiving bottom plate 102, and a receiving translation drive 103. The receiving bottom plate 102 is slidably mounted on the receiving base 101 along a horizontal second direction, and the two receiving seats 110 are spaced apart on the receiving bottom plate 102 along the second direction. The receiving translation drive 103 is mounted on the receiving base 101, and its actuating end is connected to the receiving bottom plate 102. The receiving translation drive 103 can drive the receiving bottom plate 102 to move along the second direction, so that the two receiving seats 101 alternately dock with the discharge end 301 of the cap feeding vibratory feeder 300, allowing the receiving assembly 100 to receive two caps sequentially. The second direction is perpendicular to the first direction, which is the Y direction in the figure.

[0054] Furthermore, the cap mounting mechanism 200 includes two material-picking and pressing components, which are spaced apart along the second direction, and the distance between the two material-picking and pressing components is the same as the distance between the two receiving seats 110. The two material-picking and pressing components can simultaneously adsorb and press the two caps, improving the material loading and assembly efficiency of the caps.

[0055] For example, such as Figure 1 , Figure 3 and Figure 4 As shown, the receiving assembly 100 also includes a cap baffle plate 104, which is installed on the receiving base 101. The cap baffle plate 104 extends to the side of the discharge end 301 of the cap feeding vibratory plate 300 in the second direction. When the receiving translation drive 103 drives the receiving seat 110 after receiving the material to move in the second direction, the cap baffle plate 104 blocks the inlet 112 to limit the cap in the receiving groove 111, preventing the cap from falling out of the receiving groove 111 or shifting, thereby improving reliability.

[0056] For example, such as Figure 4 As shown, the upper surface of the receiving base plate 102 is provided with a receiving limiting groove 105, and the receiving seat 110 is installed in the receiving limiting groove 105. One end of the receiving seat 110 is provided with a feeding port 112, which extends out of the receiving base plate 102 toward the pressure cap feeding vibrating plate 300. This facilitates the positioning and installation of the receiving seat 110 on the receiving base plate 102, and also facilitates the docking of the end of the receiving seat 110 with the feeding port 112 with the pressure cap feeding vibrating plate 300, reducing the gap between the two.

[0057] For example, such as Figure 3 and Figure 4As shown, the receiving assembly 100 also includes a receiving translation guide rail 106 and a receiving translation guide block 107. The receiving translation guide rail 106 is fixed to the receiving base 101 along the second direction, and the receiving translation guide block 107 is fixed to the lower surface of the receiving base plate 102. The receiving translation guide block 107 is slidably connected to the receiving translation guide rail 106, providing a reliable guiding effect for the sliding of the receiving base plate 102 along the second direction.

[0058] For example, the receiving translation drive 103 adopts a linear drive such as a linear cylinder or an electric actuator.

[0059] For example, such as Figures 1-3 and Figure 5 As shown, the material handling and pressing assembly also includes a pressing adapter block 202. The upper end of the pressing adapter block 202 is connected to the execution end of the material handling and pressing drive 201 via a pressing floating joint 203. The lower end of the pressing adapter block 202 is connected to the upper end of the material handling and pressing fixture 210. An air extraction pipe is also installed through the pressing adapter block 202, and the air vent connecting the air extraction pipe to an external vacuum equipment is located in the pressing adapter block 202. The pressing floating joint 203 adopts a floating joint as used in the prior art, which can provide floating downward pressure for the pressure cap, avoiding damage to the pressure cap or the lens to be assembled. The pressing adapter block 202 and the material handling and pressing fixture 210 are sealed together, and the air extraction pipe is installed through both the pressing adapter block 202 and the material handling and pressing fixture 210.

[0060] For example, the lower end of the pressing adapter block 202 is detachably connected to the upper end of the material-taking pressing fixture 210. When assembling different models or sizes of caps, the corresponding model or size of the material-taking pressing fixture 210 can be replaced accordingly, without the need to redesign the cap mounting mechanism 200 or replace other components on the cap mounting mechanism 200, thereby improving the versatility of the equipment and saving equipment costs.

[0061] For example, the lower end of the pressure adapter block 202 and the upper end of the material handling pressure fixture 210 can be detachably connected by means of snap-fit, threaded connection or other means.

[0062] For example, such as Figures 1-3 and Figure 5 As shown, the cap mounting mechanism 200 also includes a material picking and pressing base 204, a material picking and pressing mounting frame 205, and a cap translation drive 206. The material picking and pressing mounting frame 205 is slidably mounted on the material picking and pressing base 204 along a first direction, and two material picking and pressing components are symmetrically mounted on both sides of the material picking and pressing mounting frame 205. The cap translation drive 206 is mounted on the material picking and pressing base 204, and the actuator of the cap translation drive 206 is connected to the material picking and pressing mounting frame 205. The cap translation drive 206 can drive the material picking and pressing mounting frame 205 to move along the first direction, so that the two material picking and pressing components can be transferred between the cap picking station and the cap pressing station.

[0063] For example, such as Figures 1-3 and Figure 5 As shown, the cap mounting mechanism 200 also includes a cap translation guide rail 209 and a cap translation guide block 2091. The cap translation guide rail 209 is disposed on the material picking and pressing mounting frame 205 along the first direction. The cap translation guide block 2091 is fixed to the material picking and pressing base 204. The cap translation guide block 2091 and the cap translation guide rail 209 are slidably disposed relative to each other along the first direction, providing guidance for the sliding of the two material picking and pressing components along the first direction.

[0064] For example, such as Figures 1-3 and Figure 5 As shown, the cap mounting mechanism 200 also includes two material picking and pressing guide rails 207 and two material picking and pressing guide blocks 208. The two material picking and pressing guide rails 207 are both vertically arranged on the material picking and pressing mounting frame 205. The two material picking and pressing guide blocks 208 are correspondingly fixed to the two pressing adapter blocks 202, and the two material picking and pressing guide blocks 208 are respectively slidably arranged relative to the two material picking and pressing guide rails 207 in the vertical direction.

[0065] For example, the material handling and pressing drive 201 adopts a linear drive such as a linear cylinder or an electric actuator.

[0066] For example, the gland translation drive 206 adopts a linear drive such as a linear cylinder or an electric actuator.

[0067] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
