Description

Technical Field

[0001] This utility model belongs to the field of glass processing technology, specifically relating to a dual-station glass storage machine with error prevention function. Background Technology

[0002] In the glass production process, injection-molded edge-sealed glass products are temporarily stored in a glass storage machine, awaiting the next trimming operation. However, due to production space limitations and short production lines, injection-molded edge-sealed glass products are often directly subjected to trimming operations without sufficient cooling. This results in the edge-sealed glass, which has not received enough cooling time, being prone to damaging the adhesion between the injection-molded edge-sealing material and the glass during trimming, causing quality defects such as delamination between the edge-sealing material and the glass. Based on the above factors, the structure and functions of the glass storage machine are very important. In this field, more research is focused on the automatic storage and unloading functions of the glass storage machine. For example, invention patent CN114701858 A discloses a glass storage machine, including a frame, a conveying device for horizontally conveying glass, a lifting device for lifting the glass on the conveying device or returning it to the conveying device, a detection device for detecting whether the glass is at a set lifting height or on the conveying device, and a PLC controller for receiving signals from the detection device and controlling the operation of the conveying device and the lifting device. This invention utilizes a detection device to monitor the glass position and, in conjunction with a PLC controller, achieves automatic glass storage and unloading. It can precisely and quickly switch between glass storage and conveying states, improving operational efficiency. However, the glass storage machine described above cannot solve the problem of glass cooling between the injection molding and trimming processes. Summary of the Invention

[0003] The purpose of this invention is to provide a dual-station glass storage machine with error prevention function, which prompts the operator to store and retrieve the glass in the storage position in the correct order through indicator lights, so as to avoid operational errors and ensure that the glass reaches the necessary cooling time.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A dual-station wafer storage machine with error prevention function includes a dual-station rotating device, a locking device, and a controller. The dual-station rotating device includes a base and a dual-station rotating frame. The dual-station rotating frame is rotatably mounted on the base and is equipped with a locking device to limit the rotation of the dual-station rotating frame. The dual-station rotating frame includes a main frame and stations A and B arranged on both sides of the main frame. Stations A and B each include multi-layer glass support members with longitudinal gaps. Each layer of glass support member is equipped with a detector and an indicator light. The controller is connected to the detector, the locking device, and the indicator light.

[0006] The above solution, by installing glass detectors and operation indicator lights at the storage positions, prompts operators to correctly store and retrieve the glass in the storage positions in the correct order, avoiding operator errors, achieving first-in-first-out storage and retrieval control, and ensuring that the glass reaches the necessary cooling time.

[0007] Preferably, the locking device includes a locking pin, a locking cylinder, and a solenoid valve. The locking cylinder is mounted on the base, and its movable end is fixedly connected to the locking pin. The locking cylinder is connected to the controller through the solenoid valve to drive the locking pin to move up and down.

[0008] Preferably, the locking cylinder is a single-acting cylinder, and a return spring is sleeved outside the locking pin, with its two ends respectively abutting against the steps of the single-acting cylinder and the locking pin.

[0009] Preferably, the dual-station rotating device further includes a rotating chassis, the dual-station rotating frame is fixed on the rotating chassis, the rotating chassis is rotatably mounted on the base, and a locking device is provided to limit the rotation of the rotating chassis.

[0010] Preferably, it also includes a manual latch, with the latch mounting base fixed on the dual-station rotating frame, and the latch can be moved up and down to insert into or retract from the latch hole on the base.

[0011] Preferably, the detector can be an ultrasonic sensor, an infrared sensor, a laser sensor, or a limit switch.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. By installing a glass detector and operation indicator light at the storage position, the operator is prompted to store and retrieve the glass in the storage position in the correct order, avoiding operator errors, achieving first-in-first-out storage and retrieval control, ensuring that the glass reaches the necessary cooling time, and solving the problem of injection molding product delamination caused by insufficient static cooling time.

[0014] 2. The locking device for workstation switching has a mechanical error prevention function. If the preset conditions for workstation switching are not met, the workstation switching will remain locked. Even if the power supply and compressed air supply are cut off, the locked state will remain to prevent the operator from switching the workstation by mistake.

[0015] 3. The dual-station wafer storage machine achieves station switching through rotation, effectively alleviating the problem of limited production space; it is also equipped with lockable load-bearing wheels, and only requires one 220V 1A single-phase AC power cord and one air pipe with a diameter of about 6 mm (air pressure 0.3-0.8MPa), with low resource requirements, small footprint, reliable operation, and convenient movement.

[0016] 4. The first-in-first-out operation prompts and error prevention functions of this utility model avoid operational errors by production personnel and ensure that the static cooling time of injection molded products is not less than the product cycle time of 13 pieces (determined by the number of glass support layers).

[0024] To make the objectives and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 , 2 As shown in Figures 4 and 5, this utility model provides a dual-station wafer storage machine with error prevention function, including a dual-station rotating device 1, a locking device 2, a detector 4, an indicator light 5, and a controller 3. The controller 3 is installed on the dual-station rotating device 1 and is connected to the locking device 2, the detector 4, and the indicator light 5.

[0026] The dual-station rotating device 1 includes a base 11, a rotating chassis 13, a dual-station rotating frame 12, and a rotating frame main shaft 14. The dual-station rotating frame 12 is fixed on the rotating chassis 13, and the dual-station rotating frame 12 has a built-in bearing seat 16. The dual-station rotating frame 12 is rotatably connected to the rotating frame main shaft 14 through bearings 15. The lower end of the rotating frame main shaft 14 passes through the central hole of the rotating chassis 13 and is fixed on the base 11. Lockable load-bearing wheels 7 are provided at the four corners of the base 11, which can push the chip storage machine to move.

[0027] like Figure 3 As shown, the locking device 2 includes a locking pin 21, a locking cylinder 22, and a solenoid valve. The locking cylinder 22 is mounted on the base 11 via a cylinder fixing plate 24, and the movable end of the locking cylinder 22 is fixedly connected to the locking pin 21. The locking cylinder 22 is connected to the controller 3 via the solenoid valve. It receives instructions from the controller 3 to operate, thereby driving the locking pin 21 to move up and down, thus controlling the locking pin 21 to insert or retract into the pin hole of the chassis, achieving the function of locking or opening the chip storage machine station switching, effectively solving the problem of limited space.

[0028] The locking device 2 can also be mainly composed of a locking pin 21, a locking cylinder 22, a return spring 23, and a solenoid valve. The locking cylinder 22 is a single-acting cylinder, and the return spring 23 is sleeved on the locking pin 21, with its two ends abutting against the steps of the single-acting cylinder and the locking pin 21, respectively. The locking cylinder 22 is connected to the controller 3 through the solenoid valve and operates upon receiving instructions from the controller 3. With this design, the locking device 2 has a mechanical error prevention function. The locking cylinder 22 is a single-acting cylinder with spring return, which has the characteristic of power-off retention. If the preset conditions for workstation transition are not met, the workstation transition will remain locked, even if the power supply and compressed air supply are cut off.

[0029] The dual-station rotating frame 12 includes a main frame 121 and stations A122 and B123 located on both sides of the main frame 121. In this embodiment, station A122 is the injection molding station, and station B123 is the trimming station. However, the stations are not fixed and can be switched by rotating the dual-station rotating frame 12. That is, after switching, station A122 is the trimming station, and station B123 is the injection molding station. The injection molding station and the trimming station have the same structure, both including 13 layers of glass support members 124 with longitudinal gaps, i.e., storage positions. The injection molding station and the trimming station can each hold 13 pieces of glass. The injection molding station is named from top to bottom as injection side position 1, injection side position 2, ..., injection side position 13; the trimming station is named from top to bottom as trimming side position 1, trimming side position 2, ..., trimming side position 13. Each glass support component 124 is equipped with a detector 4 and an indicator light 5. At the injection molding station, the detectors 4 are named sequentially from top to bottom as Injection Side Position 1 Detector 4, Injection Side Position 2 Detector 4, ..., Injection Side Position 13 Detector 4; the indicator lights 5 are named sequentially from top to bottom as Injection Side Position 1 Indicator Light 5, Injection Side Position 2 Indicator Light 5, ..., Injection Side Position 13 Indicator Light 5. At the trimming station, the detectors 4 are named sequentially from top to bottom as Trimming Side Position 1 Detector 4, Trimming Side Position 2 Detector 4, ..., Trimming Side Position 13 Detector 4; the indicator lights 5 are named sequentially from top to bottom as Trimming Side Position 1 Indicator Light 5, Trimming Side Position 2 Indicator Light 5, ..., Trimming Side Position 13 Indicator Light 5. The controller 3 stores information about these detectors 4 and indicator lights 5. The detectors 4 detect whether there is glass on the glass support component 124 and send the information to the controller 3, which then controls the indicator lights 5 to turn on or off based on the presence of glass.

[0030] The glass support 124 can be a support plate or a structure consisting of two horizontally arranged support rods on the same straight line. In this embodiment, the glass support 124 is composed of four horizontally fixed support rods at equal intervals to the main frame 121. A hollow column 125 is provided at the center of the main frame 121, and the lower end of the hollow column 125 is connected to the bearing seat 16. The detector 4 and indicator light 5 are installed on the hollow column 125 at the horizontal positions corresponding to the glass support 124. Cables can be installed inside the hollow column 125.

[0031] Preferably, this solution also includes a manual latch 6, with the latch mounting base fixed to the side of the dual-station rotating frame 12. The latch can move up and down to insert into or retract from the latch hole on the base 11. The latch is only used as additional reinforcement during the movement of the wafer storage machine.

[0032] The detector 4 can be an ultrasonic sensor, an infrared sensor, a laser sensor, or a limit switch. In this embodiment, an ultrasonic sensor is preferred. All 26 glass support members 124 at both workstations are equipped with ultrasonic sensors to detect in real time whether there is glass on the glass support member 124. The purpose of using ultrasonic sensors is to adapt to transparent glass products. If the produced glass product has ink printing in the detection area or is covered with opaque edge-sealing injection molding material, an infrared sensor or a laser sensor can also be used. If the sensor is in contact with the glass edge, a limit switch with a flexible universal swing arm can be used to detect the glass, which can significantly reduce equipment costs.

[0033] This embodiment uses a Siemens S7-200 SMART PLC as the main controller 3, specifically an ST30CPU + EM DR32 digital input / output expansion module. It collects, responds to, and prompts the glass storage and retrieval status on each glass support 124, and determines whether the set station transition conditions are met. If the conditions are not met, the locking pin 21 is locked, prohibiting station transition; if the conditions are met, the locking pin 21 is opened, and the operator rotates the dual-station rotary frame 12 to transition to the new station. When the station transition is complete, the locking pin 21 automatically locks again.

[0034] The working principle of this utility model is as follows:

[0035] (1) After the chip storage machine is powered on and initialized, on the injection side, the controller 3 checks each chip storage position (glass support 124) from top to bottom to see if there is glass. First, the detector 4 checks the top chip storage position 1. If it is empty, the controller 3 controls the indicator light 5 of position 1 to light up, prompting the operator to store the injection-molded glass in chip storage position 1 (if there is glass when checking chip storage position 1, it will directly jump to checking position 2). When the glass is correctly placed in storage slot 1, indicator light 5 for slot 1 is turned off. Controller 3 checks if there is glass in storage slot 2. If there is no glass in slot 2, indicator light 5 for slot 2 is turned on, prompting the operator to store the next piece of molded glass in slot 2. When glass is correctly placed in slot 2, indicator light 5 for slot 2 is turned off. Glass is placed in this manner until the bottom slot 13 on the injection side is found to be filled with glass. Controller 3 then turns off all indicator lights 5 on the injection side, indicating that no more glass can be placed. In other words, after the chip storage machine is powered on and initialized, controller 3 first turns on the indicator light 5 of the first empty storage slot from the top, then sequentially indicates the storage operation is complete, and outputs a status signal indicating that the storage operation is complete. The electrical diagram of this solution is shown below. Figure 6 As shown.

[0036] On the trimming side, after the wafer storage machine is powered on and initialized, controller 3 checks each wafer storage position from top to bottom for glass. First, it checks the topmost position 1 (if no glass is found in position 1, it skips directly to checking position 2). If glass is found, controller 3 illuminates indicator light 5 for position 1, prompting the operator to start trimming from position 1. Once controller 3 detects that the glass in position 1 has been removed, indicator light 5 turns off. It then checks position 2 for glass. If glass is found in position 2, indicator light 5 illuminates, prompting the operator to remove the glass from position 2 for trimming. After the glass in position 2 is removed, indicator light 5 turns off, and controller 3 checks position 3 for glass. If there is glass in slot 3, indicator light 5 for slot 3 will light up, prompting the operator to remove the glass from slot 3 for trimming... When the glass in slot 13 at the bottom is removed, indicator light 5 for slot 13 will turn off (all indicator lights 5 for all 13 slots will be off), and controller 3 will determine that all slots on the trimming side are empty. In other words, after the wafer storage machine is powered on and initialized, controller 3 will light up indicator light 5 for the first slot containing glass from the top, instructing the operator to remove wafers for trimming sequentially from top to bottom until the trimming side is completely empty, and will output a status signal.

[0037] Whether it's loading sheets onto the injection side or unloading sheets from the trimming side, if the operator does not load or unload sheets according to the position indicated by indicator light 5 on the controller 3 (i.e., the loading or unloading position is not the storage position indicated by indicator light 5), the controller 3 will detect that the operation is complete, but the position indicated by indicator light 5 will remain unchanged until the operator completes the loading or unloading operation at the storage position indicated by indicator light 5. Only then will indicator light 5 turn off, and the indicator light 5 of the next storage position that needs to be operated will light up. This method reminds the operator to correctly complete the operation according to the first-in-first-out (FIFO) principle set by the controller 3. The FIFO operation rule of this utility model is a conventional method in the prior art.

[0038] (2) On the injection molding side, the glass is stored sequentially from top to bottom, starting from the top position 1, until all 13 layers are filled. On the trimming side, the glass is removed sequentially from top to bottom, starting from the top position 1, until all 13 layers are removed. When both conditions are met, the controller 3 controls the locking cylinder 22 to work, causing the locking pin 21 to disengage from the pin hole of the chassis. The operator then rotates the dual-station rotating frame 12 to switch positions. During operation, the glass loading on the injection molding side and the glass removal on the trimming side do not affect each other and can be carried out independently according to the actual operation of the process.

[0039] The above embodiments are merely specific examples to further illustrate the purpose, technical solution, and beneficial effects of this utility model, and this utility model is not limited thereto. Any modifications, equivalent substitutions, improvements, etc., made within the scope of the disclosure of this utility model are included within the protection scope of this utility model.
