[0002] In the related art, a lens casting machine is used to inject corresponding glue into a glue injection mold to make a lens during lens production.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the scheme in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0044] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0045] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0046] The utility model provides a tape sealing device for sealing a sealing rubber cover to a glue injection port of a glue injection mold. Figure 1 , Figure 2 and Figure 4, the tape sealing device comprises:

[0047] The pressing mechanism 100 includes a pressing member 110, a mounting member 120 and an elastic member 130. The pressing member 110 is elastically connected to the mounting member 120 via the elastic member 130.

[0048] The driving mechanism 200 is connected to the mounting member 120 and is used to drive the mounting member 120 to drive the pressing member 110 and the elastic member 130 to move, so that the pressing member 110 abuts against the sealing glue, so that the sealing glue cover is sealed on the injection port of the injection mold 600.

[0049] When in use, the driving mechanism 200 first drives the pressing mechanism 100 to move to the position where the sealing glue is located, and then the pressing member 110 is in contact with the sealing glue. At this time, the force between the sealing glue and the pressing member 110 causes the pressing member 110 to move in the direction of the compression elastic member 130, and the elastic force generated by the compression elastic member 130 causes the pressing member 110 to maintain the contact state with the sealing glue, so that the sealing glue maintains a suitable tension and the sealing glue seals the injection port. It should be noted that in order to avoid the situation where the pressure between the pressing member 110 and the sealing glue is too small, the moving distance of the pressing member 110 is usually larger so that the pressure between the two can be adjusted by the elastic member 130.

[0050] Among them, the pressing member 110 is used to compress the sealing glue. It can be understood that in order to avoid the pressing member 110 from damaging the sealing glue during the pressing process, the surface of the pressing member 110 in contact with the sealing glue is set to a curved surface to reduce the impact of the pressing member 110 on the sealing glue.

[0051] The elastic member 130 is an elastic structure, which can be a spring, a leaf spring or a rubber sleeve. The elastic force provided by the elastic member 130 enables the pressing member 110 to be pressed on the sealing glue with appropriate pressure. Even if the type, length and position of the sealing glue change, the compression amount of the elastic member 130 will change accordingly, so that the pressure between the pressing member 110 and the sealing glue is relatively stable, thereby better achieving the sealing of the mold and reducing the occurrence of situations such as the sealing glue tension being too tight or too loose. There are many ways to connect the elastic member 130 with the mounting member 120 and the pressing member 110. Taking the spring as an example, the two ends of the spring can be welded to the mounting member 120 and the pressing member 110 respectively, or by bonding, clamping and other methods. The utility model does not limit this. In addition, the elastic member 130 is also flexible and can absorb the impact and vibration caused by the pressing member 110, preventing the pressing member 110 from hitting the injection mold 600 when the movement stroke is too large, causing the pressing member 110 or the injection mold 600 to be damaged.

[0052] The driving mechanism 200 can be a gear rack transmission mechanism, which drives the gear to rotate through the motor 230, thereby driving the rack meshing with the gear to move forward and backward. At this time, the clamping mechanism 100 is connected to the rack to achieve the forward and backward movement of the clamping mechanism 100, thereby compressing the sealing glue. Similarly, the driving mechanism 200 can also be a hydraulic cylinder, a cylinder, a belt transmission mechanism, a linear motor 230, etc. By connecting the driving end of the driving mechanism 200 to the clamping mechanism 100, the clamping mechanism 100 can be driven to move back and forth. The specific connection method between the drive mechanism 200 and the mounting member 120 is not limited here, and designers can make reasonable designs according to actual needs; for example, when the drive mechanism 200 and the mounting member 120 are detachably connected, the drive mechanism 200 can be, but is not limited to, fixedly connected to the mounting member 120 by at least one of screw connection, snap connection, or plug-in connection; for another example, when the drive mechanism 200 and the mounting member 120 are non-detachably connected, the drive mechanism 200 can be, but is not limited to, fixedly connected to the mounting member 120 by welding.

[0053] The utility model provides an elastic member 130 between the pressing member 110 and the mounting member 120, so that when the pressing member 110 compresses the sealing glue, if the pressure between the two is too large, the excessive pressure will cause the pressing member 110 to compress the spring, thereby reducing the pressure between the pressing member 110 and the sealing glue, so that the pressure between the pressing member 110 and the sealing glue is maintained in a stable state. Even if the length and position of the torn sealing glue change, it will not cause too much influence on the size of the pressure applied by the pressing member 110 on the sealing glue, thereby improving the efficiency and yield of the sealing glue.

[0054] like Figure 1 As shown, in some embodiments, the clamping mechanism 100 further includes:

[0055] A guide rail 140, the guide rail 140 is fixed on the mounting member 120;

[0056] A slider 150, the slider 150 can be slidably mounted on the guide rail 140, wherein the sliding direction of the slider 150 along the guide rail 140 is parallel to the direction in which the drive mechanism 200 drives the mounting member 120 to move;

[0057] The pressing member 110 is fixedly connected to the slider 150;

[0058] The elastic member 130 is disposed between the pressing member 110 and the mounting member 120 along the sliding direction of the slider 150 on the guide rail 140 .

[0059] Specifically, the driving mechanism 200 first drives the mounting member 120, the pressing member 110 and the elastic member 130 to move, and causes the pressing member 110 to press against the sealing glue. At this time, the pressing member 110 and the sealing glue generate an interactive pressure, which prompts the pressing member 110 to move in the opposite direction, that is, the pressing member 110 drives the slider 150 to slide on the guide rail 140 and compress the elastic member 130, so as to adjust the pressure between the pressing member 110 and the sealing glue. The compression direction of the elastic member 130 is controlled to be the same as the sliding direction of the slider 150, but the elastic member 130 provides a stable elastic force, while preventing the elastic member 130 from being deformed or damaged, thereby affecting the service life of the elastic member 130 and the pressing effect of the pressing member 110 on the sealing glue. The guide rail 140 and the mounting member 120 can be fixedly connected by welding, bonding, threaded connection, etc., and the connection between the slider 150 and the pressing member 110 is similar.

[0060] like Figure 1 and Figure 2 As shown, in some embodiments, the clamping mechanism 100 further includes:

[0061] A limit block 160 is provided at at least one end of the guide rail 140 , and the limit block 160 is used to prevent the slider 150 from slipping off the guide rail 140 .

[0062] The limit block 160 is usually arranged to protrude from the surface of the guide rail 140, so that the limit block 160 can block the movement of the slider 150, thereby preventing the slider 150 from escaping from the guide rail 140. It can be understood that the limit block 160 can be directly arranged on the guide rail 140, or can be arranged on the mounting member 120 and abutted against the end of the guide rail 140 to achieve the restriction of the slider 150. Exemplarily, in this embodiment, the limit block 160 is in the shape of a fence, which is arranged on the mounting member 120 by welding or bonding, and is located at both ends of the guide rail 140, thereby preventing the slider 150 from escaping from the guide rail 140.

[0063] like Figure 1 and Figure 2 As shown, in some embodiments, the clamping mechanism 100 further includes:

[0064] A guide rod 170, the guide rod 170 is fixedly connected to the mounting member 120;

[0065] The pressing member 110 is slidably connected to the guide rod 170;

[0066] The elastic member 130 is sleeved on the guide rod 170 , and two ends of the elastic member 130 abut against the pressing member 110 and the mounting member 120 respectively.

[0067] The guide rod 170 serves to limit the moving direction of the pressing member 110, and the elastic member 130 is sleeved on the guide rod 170 to ensure that the compression direction of the elastic member 130 is the direction of the guide rod 170, so that the elastic force provided is more stable, and the adjustment effect of the pressure between the pressing member 110 and the sealing glue is also relatively stable. Exemplarily, in this embodiment, there are two guide rods 170, which are arranged in parallel on the mounting member 120, and the pressing member 110 has two through holes corresponding to the positions of the guide rods 170. The sliding connection between the pressing member 110 and the guide rod 170 is achieved through the sleeve connection between the guide rod 170 and the through holes; and the two guide rods 170 can prevent the pressing member 110 from tilting, thereby stabilizing the pressing effect of the pressing member 110 on the sealing glue.

[0068] like Figure 1 and Figure 2 As shown, in some embodiments, the mounting member 120 includes:

[0069] A connecting arm 121, the bottom end of the connecting arm 121 is connected to the driving mechanism 200;

[0070] A support plate 122, the support plate 122 is fixedly connected to the top end of the connecting arm 121;

[0071] A connecting seat 123, the connecting seat 123 is fixed on the supporting plate 122;

[0072] One end of the guide rod 170 is fixedly connected to the connecting seat 123 .

[0073] The connecting arm 121 is used to connect the driving mechanism 200 and the mounting member 120. By setting the structure of the connecting arm 121 as needed, the positions of the support plate 122 and the connecting seat 123 are adjusted, so that the pressing member 110 is in a suitable position to achieve the contact with the sealing glue. The connection between the connecting arm 121, the support plate 122 and the connecting seat 123 can be welding, bonding, clamping, threaded connection, etc., and the present invention does not limit this.

[0074] like Figure 1 and Figure 2 As shown, in some embodiments, the driving mechanism 200 includes:

[0075] Screw rod 210;

[0076] The screw rod seat 220 is sleeved on the screw rod 210 and connected to the connecting arm 121;

[0077] The motor 230 is in transmission connection with the screw rod 210 to drive the screw rod 210 to rotate.

[0078] When the motor 230 drives the screw rod 210 to rotate, the screw rod 210 and the screw rod seat 220 are connected by threads, so that the screw rod seat 220 moves along the screw rod 210, thereby driving the connecting arm 121 connected to the screw rod seat 220 to move along the screw rod 210, thereby driving the mounting member 120 and the pressing member 110 to move. The transmission between the screw rod 210 and the screw rod seat 220 has high positioning accuracy and load capacity, and has good stability, which helps to control the pressure between the pressing member 110 and the sealing glue.

[0079] like Figure 3 As shown, in some embodiments, the screw seat 220 is provided with threaded holes 221 at intervals along the first direction, and the connecting arm 121 is provided with a first U-shaped groove 121a corresponding to the threaded hole 221, and the first U-shaped groove 121a is bolted to the threaded hole 221.

[0080] By passing the bolt through the first U-shaped groove 121a on the connecting arm 121 and screwing it into the threaded hole 221 on the screw seat 220 to provide sufficient fixing force, the screw seat 220 is fixedly connected to the connecting arm 121. And the disassembly and installation of the connecting arm 121 and the screw seat 220 are realized by the threaded connection, which is convenient for users to repair, clean and replace. The number and position of the threaded holes 221 can be adjusted according to actual needs. For example, in this embodiment, there are three threaded holes 221, and the first direction is perpendicular to the moving direction of the screw seat 220. It can be understood that the width and depth of the first U-shaped groove 121a should match the position and size of the threaded hole 221 so that the bolt connection can be smoothly performed.

[0081] like Figure 3 As shown, in some embodiments, the connecting arm 121 is provided with a second U-shaped groove 121 b along the second direction, and the supporting plate 122 is configured with a protrusion 122 a , which is connected to the second U-shaped groove 121 b .

[0082] There are many ways to connect the protrusion 122a and the second U-shaped groove 121b. For example, the protrusion 122a can be pressed into the second U-shaped groove 121b through interference fit, so that the connecting arm 121 and the mounting plate are tightly connected; or they can be connected by bonding. Preferably, in this embodiment, a strip through hole 121c is provided on the side wall of the second U-shaped groove 121b, and a threaded through hole is provided at the position of the protrusion 122a corresponding to the strip through hole 121c. The fixing between the connecting arm 121 and the support plate 122 can be achieved by passing a bolt through the strip through hole 121c and threadedly connected with the threaded through hole; if the connecting arm 121 needs to be replaced, the bolt can be unscrewed, which is simple to operate and has a firm connection.

[0083] like Figure 2As shown, in some embodiments, the pressing member 110 includes a connecting section 111 and an extending section 112. The connecting section 111 is horizontally arranged, one end of the connecting section 111 is connected to the elastic member 130, and the other end is connected to the extending section 112. The extending section 112 is arranged to extend downwardly at an angle from one end of the connecting section 111 away from the elastic member 130.

[0084] The horizontally arranged connecting section 111 is convenient for installation and also facilitates the cooperation between the pressing member 110 and other structures, so that the pressing member 110 can slide more smoothly. The inclined extension section 112 can increase the contact area with the tape, so that the pressing member 110 can better contact the surface of the sealing adhesive to provide continuous pressing force and ensure that the sealing adhesive is always in a tensioned state.

[0085] like Figure 4 As shown, the present invention further proposes a lens casting machine including a frame 300, a clamping device 400, a rotating device, a glue tearing device 500, a glue injection device and a tape sealing device. The specific structure of the tape sealing device refers to the above embodiment. Since the present lens casting machine adopts all the technical solutions of all the above embodiments, it has at least all the technical effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the clamping device 400 is arranged on the frame 300, and the clamping device 400 is used to position the injection mold 600; the rotating device is arranged on the frame 300, and the rotating device is used to drive the injection mold 600 to rotate; the glue tearing device 500 is arranged on the frame 300, and the glue tearing device 500 is used to tear off the sealing glue covering the injection port of the injection mold 600; the injection device is arranged on the frame 300 and located above the clamping device 400, and the injection device is used to inject glue through the injection port of the injection mold 600 after the sealing glue at the injection port is torn off by the glue tearing device 500; the tape sealing device is arranged on the frame 300, and is used to seal the sealing glue cover to the injection port after the injection device injects glue into the injection mold 600 through the injection port.
