Description

Technical Field

[0001] The utility model relates to the technical field of display screen assembly equipment, in particular to a vehicle-mounted display screen pre-pressing device. Background Art

[0002] The screen and back shell of the car display screen are usually bonded with various glues. The characteristics of the glue include the opening time and the bonding pressure range. Exceeding the glue opening time or the bonding pressure not being within the specified range will have a significant impact on the product quality. In addition, due to different product sizes, different glue opening times and bonding pressures are selected, and the bonding time and bonding pressure need to be adjusted accordingly. Then, in the prior art, the screen and the back shell are usually pre-pressed manually or semi-automatically. When semi-automatic pre-pressing is used, the product is manually loaded and unloaded. Both of these pre-pressing methods cannot guarantee the rationality of the pre-pressing time and pre-pressing pressure, which may affect the pre-pressing quality and have low production efficiency. Utility Model Content

[0003] The utility model provides a vehicle-mounted display screen pre-pressing device, which can improve the quality of pre-pressing the vehicle-mounted display screen and the rear shell, and improve the pre-pressing efficiency.

[0004] The technical solution of the utility model to solve the above technical problems is as follows:

[0005] A vehicle-mounted display screen pre-pressing device comprises a cabinet, a product conveying line installed on the cabinet, a movably mounted product carrier on the product conveying line, a lifting mechanism installed on the cabinet and located directly below the moving track of the product carrier, a pre-pressing support frame installed on the cabinet, and a pre-pressing mechanism installed on the pre-pressing support frame, wherein the product carrier is provided with a product placement slot, and the pre-pressing mechanism is located directly above the lifting mechanism.

[0006] The beneficial effects of the utility model are as follows: during pre-pressing, the pre-pressed screen and back shell are placed on the product carrier, glue is pre-coated between the screen and the back shell, and then the product carrier is moved to the bottom of the jacking mechanism through the product conveyor line within the glue opening time, and the product carrier is lifted toward the pre-pressing mechanism by the jacking mechanism, and pre-pressing is performed under the joint action of the jacking mechanism and the pre-pressing mechanism until the pre-pressing is completed, the jacking mechanism descends, so that the product carrier falls onto the product conveyor line, and the product carrier with the pre-pressed product is transported away through the product conveyor line to perform the pre-pressing action of the next product; a mechanically controllable pre-pressing method is adopted to replace the manual or semi-automatic pre-pressing method in the prior art, so as to realize the conveying of pre-pressed products, and the pre-pressing time and pre-pressing pressure are both controllable, and the pre-pressing pressure is balanced in each part, thereby improving the pre-pressing quality and improving the pre-pressing efficiency.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the product conveyor line includes two groups of conveyor frames installed on the cabinet, two groups of chains installed on the two groups of conveyor frames respectively, and a driving member connected to the two groups of chains for simultaneous transmission, the product carrier is installed on the two groups of chains, and the driving member is installed on the cabinet.

[0009] The beneficial effect of adopting the above further scheme is: when the product carrier is transmitted through the product conveyor line, the product carrier is placed on two sets of chains, the driving member is started, and the two sets of chains are driven until the product carrier moves to the top of the lifting mechanism, and the driving member is closed to perform the pre-pressing action.

[0010] Furthermore, both groups of conveying frames are equipped with limiting members, which include a limiting seat connected to the conveying frame, a linear driving component No. 1 installed on the limiting seat, and a limiting plate connected to the linear driving component No. 1. The linear driving component No. 1 is located between the two groups of chains, and the driving end is vertically retracted, and the limiting plate is connected to the driving end of the linear driving component No. 1.

[0011] The beneficial effect of adopting the above-mentioned further scheme is: when the product carrier is moved to the top of the lifting mechanism through the product conveyor line, the No. 1 linear drive component drives the limit plate to move to the front of the product carrier, blocking the product carrier from continuing to move under the action of inertia, thereby ensuring that the product carrier stops at a predetermined position to facilitate subsequent accurate pre-pressing action; after the pre-pressing is completed, the No. 1 linear drive component drives the limit plate to retract and move the product carrier away through the product conveyor line.

[0012] Furthermore, the conveying frame includes two bases both installed on the cabinet and rails installed on the two bases at the same time, and the two groups of chains are respectively installed on the two rails; the rails of one group of the conveying frames are rotatably connected to a screw rod and connected to at least one guide rod, and one end of the screw rod and the guide rod are both connected to the rails, and the rails of the other group of the conveying frames are threadedly connected to the other end of the screw rod and slidably connected to the other end of the guide rod, and the screw rod is also transmission-connected to a driving component.

[0013] The beneficial effect of adopting the above further scheme is that before the product carrier is transported through the product conveyor line, the drive component can be started to drive the screw to rotate so that the distance between the two tracks is changed to achieve the purpose of transporting product carriers of different sizes and be compatible with the pre-pressing action of more products of different sizes.

[0014] Furthermore, the lifting mechanism includes a frame installed on the cabinet, a second linear drive component installed on the frame, and a lifting frame vertically slidably connected to the frame, the driving end of the second linear drive component is vertically telescopic, and the lifting frame is connected to the driving end of the second linear drive component.

[0015] The beneficial effect of adopting the above further scheme is: when the product carrier is lifted toward the pre-pressing mechanism by the lifting mechanism, the No. 2 linear drive component is started, and the No. 2 linear drive component lifts the lifting frame upward, so that the lifting frame lifts the product carrier located above it.

[0016] Furthermore, the lifting frame includes a plurality of sliding rods vertically slidably connected to the frame and a lifting plate fixed to the upper ends of the plurality of sliding rods at the same time, the driving end of the No. 2 linear drive component is connected to the lifting plate, a plurality of positioning pins are evenly distributed on the upper side of the lifting plate, and the product carrier is provided with pin holes for inserting the positioning pins.

[0017] The beneficial effect of adopting the above further scheme is: when the product carrier is lifted toward the pre-pressing mechanism by using the lifting mechanism, the lifting plate is driven by the No. 2 linear drive component to lift the product carrier. During this process, the positioning pin is inserted into the product carrier to ensure the fixation of the position of the product carrier, thereby ensuring the accuracy of the pre-pressing.

[0018] Furthermore, the lower ends of two adjacent sliding rods are simultaneously connected to a buffer plate, and the buffer plate is connected to a buffer installed on the frame.

[0019] The beneficial effect of adopting the above further scheme is: when the lifting plate is lifted by the No. 2 linear drive component and the slide rod slides upward, the buffer plate slides synchronously. During this process, the buffer limits the upward sliding of the buffer plate to limit the lifting of the lifting plate to a fixed height to prevent excessive pre-compression.

[0020] Furthermore, a plurality of buffer pads are fixed to one side of the frame close to the jacking plate.

[0021] The beneficial effect of adopting the above further solution is that when the pre-pressing is completed and the jacking plate moves downward under the recovery action of the second linear drive component, the buffer pad buffers the descending jacking plate.

[0022] Furthermore, the pre-stressing mechanism includes a No. 1 lower pressure frame vertically slidably connected to the pre-stressing support frame, a No. 3 linear driving component installed on the pre-stressing support frame, a No. 2 lower pressure frame slidably connected to the lower end of the No. 1 lower pressure frame, and a pressure plate fixed to the lower end of the No. 2 lower pressure frame, and the driving end of the No. 3 linear driving component is vertically telescopic and connected to the No. 1 lower pressure frame.

[0023] The beneficial effect of adopting the above-mentioned further scheme is: when the lifting mechanism lifts the product carrier toward the pre-pressing mechanism, the product carrier is lifted toward the pressing plate to pre-press the product through the pressing plate. After the pre-pressing is completed, the pressing plate is recovered upward by the No. 3 linear drive component; when the pre-pressing force exceeds the gravity of the No. 2 lower pressing frame and the pressing plate, the No. 2 lower pressing frame and the pressing plate will slide upward at the same time. At this time, the No. 2 lower pressing frame and the pressing plate can be recovered by the No. 3 linear drive component.

[0024] Furthermore, the No. 2 lower pressure frame is vertically slidably connected with a force-bearing plate, and a pressure sensor is arranged between the force-bearing plate and the pressure plate.

[0025] The beneficial effect of adopting the above further scheme is that when the No. 2 lower pressure frame and the pressure plate slide upward at the same time, the force plate slides downward due to the downward pressure of the No. 1 lower pressure frame and contacts with the pressure sensor to detect the pre-pressure through the pressure sensor to achieve feedback.

The product carrier 3 is provided with a product placement slot 31, and the pre-pressing mechanism 6 is located directly above the lifting mechanism 4.

[0045] The beneficial effects of this embodiment are as follows: during pre-pressing, the pre-pressed screen and back shell are placed in the product placement groove 31 of the product carrier 3, and glue is pre-coated between the screen and the back shell. Then, within the glue opening time, the product carrier 3 is moved to the bottom of the jacking mechanism 4 through the product conveyor line 2, and the product carrier 3 is lifted toward the pre-pressing mechanism 6 by the jacking mechanism 4. Pre-pressing is performed under the joint action of the jacking mechanism 4 and the pre-pressing mechanism 6 until the pre-pressing is completed. The jacking mechanism 4 descends, so that the product carrier 3 falls on the product conveyor line 2, and the product carrier 3 with the pre-pressed product is transported away by the product conveyor line 2 to perform the pre-pressing action of the next product. A mechanically controllable pre-pressing method is used instead of the manual or semi-automatic pre-pressing method in the prior art to realize the transportation of pre-pressed products. The pre-pressing time and pre-pressing pressure are both controllable, and the pre-pressing pressure is balanced at all parts, thereby improving the pre-pressing quality and improving the pre-pressing efficiency.

[0046] Based on the above embodiments, the utility model also includes a control system, which is communicatively connected to the product conveyor line 2, the lifting mechanism 4 and the pre-pressing mechanism 6 to control the product conveyor line 2, the lifting mechanism 4 and the pre-pressing mechanism 6 to perform corresponding sequential actions.

[0047] It can be understood that the control system of the embodiment of the utility model can be a PLC controller, such as a combinational logic controller, a microprogram controller, etc., as long as it can implement the operations described in this application. Of course, the control system can also be integrated into a physical device as different modules. The utility model does not impose specific restrictions on the physical implementation method of the control system.

The product carrier 3 is installed on the two groups of chains 22, and the driving member 23 is installed on the cabinet 1.

[0050] The beneficial effect of adopting the preferred scheme in the above embodiment is that when the product carrier 3 is transmitted through the product conveyor line 2, the product carrier 3 is placed on two sets of chains 22, and the driving member 23 is started to drive the two sets of chains 22 until the product carrier 3 moves to the top of the lifting mechanism 4, and the driving member 23 is closed to perform the pre-pressing action.

[0051] On the basis of the above embodiment, the lifting mechanism 4 is arranged between two groups of conveying frames 21 .

The No. 1 linear driving component 242 is located between the two groups of chains 22, and the driving end is vertically telescopic, and the limiting plate 243 is connected to the driving end of the No. 1 linear driving component 242.

[0057] The beneficial effect of adopting the preferred scheme in the above embodiment is that when the product carrier 3 is moved to the top of the lifting mechanism 4 through the product conveyor line 2, the No. 1 linear drive component 242 drives the limit plate 243 to move to the front of the product carrier 3, blocking the product carrier 3 from continuing to move under the action of inertia, ensuring that the product carrier 3 stops at a predetermined position to facilitate subsequent accurate pre-pressing action; after the pre-pressing is completed, the No. 1 linear drive component 242 drives the limit plate 243 to be retracted, and the product carrier 3 is removed through the product conveyor line 2.

[0059] On the basis of the above embodiment, a proximity sensor 244 is further installed on the side of the limiting plate 243 facing the product carrier 3 to sense the approach of the product carrier 3 .

[0060] Furthermore, the proximity sensor 244 signal is connected to the control system, so that when the proximity sensor 244 senses the approach of the product carrier 3, the control system controls the product conveyor line 2 to slow down, so that the product carrier 3 stops at a predetermined position.

[0061] Furthermore, a buffer pad 32 is detachably connected to the contact position between the product carrier 3 and the proximity sensor 244 through screws. The buffer pad 32 can be made of rubber to form a flexible contact with the proximity sensor 244 to reduce damage.

Further, a plurality of gears are rotatably connected in the opening, and the chain 22 is simultaneously engaged with the plurality of gears to achieve tension.

[0067] Specifically, a screw rod 213 is rotatably connected to one end of the track 212 via a bearing, and at least two parallel guide rods 214 are connected to the other end.

The driving end of the No. 3 linear driving component 62 is vertically telescopic and connected to the No. 1 lower press frame 61.

[0088] The beneficial effect of adopting the preferred scheme in the above embodiment is that when the lifting mechanism 4 lifts the product carrier 3 toward the pre-pressing mechanism 6, the product carrier 3 is lifted toward the pressure plate 64 to pre-press the product through the pressure plate 64. After the pre-pressing is completed, the pressure plate 64 is retracted upward by the No. 3 linear drive component 62; when the pre-pressure exceeds the gravity of the No. 2 lower pressure frame 63 and the pressure plate 64, the No. 2 lower pressure frame 63 and the pressure plate 64 will slide upward at the same time. At this time, the No. 2 lower pressure frame 63 and the pressure plate 64 can be retracted by the No. 3 linear drive component 62.

[0089] The third linear drive component 62 can be a linear drive mechanism such as an electric cylinder or a pneumatic cylinder. The figure shows an electric cylinder, and the piston end of the electric cylinder extends vertically downward.
