Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic component processing, and in particular relates to an automatic glass loading device for photovoltaic component production. Background Art

[0002] During the production process of crystalline silicon photovoltaic modules, the entire tray of glass needs to be grabbed one by one onto the transmission line. In the existing technology, an automatic glass loading machine is used to grab and place the raw glass so that the glass can enter the next process. However, the cycle of most automatic glass loading machines is maintained at more than 15 seconds, which cannot meet the daily production cycle of the production line, resulting in the production efficiency of the production line being restricted.

[0003] The Chinese invention patent with publication number CN105059923B proposes a synchronously driven automatic glass loading machine, which requires the glass suction mechanism to repeatedly rise and fall to absorb the glass and paper. This action takes 4 to 5 seconds, and the overall beat is close to 20 seconds. In addition, the lifting action is too fast, and abnormal downtime due to mechanism wear frequently occurs. The reason for the frequent rise and fall is that the glass needs to be placed on a 1-meter-high transmission line, while the height of the entire tray of glass is only 0.4 meters, and as the glass is consumed, the height will continue to decrease. Due to this height difference, the automatic glass loading machine needs to move frequently. First, it needs to descend to a glass placement table below the transmission line, and then after grabbing the glass, it is raised and placed on the transmission line platform.

[0004] In view of the problem that the existing glass loading machines cannot meet the production line rhythm, it is necessary to propose an automatic glass loading device for photovoltaic module production to reduce the movement of the automatic glass loading machine itself, improve and optimize the rhythm of the automatic glass loading machine, thereby increasing output and reducing manufacturing costs.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions 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 in 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.

[0021] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] Embodiment 1:

[0023] Reference Figure 1 As shown, the utility model embodiment 1 provides an automatic glass loading device for photovoltaic module production, which is arranged on both sides or the front end of the photovoltaic module transmission line 3, including a glass tray placement platform 5 arranged close to the transmission line 3, which is used to carry and place a whole tray of glass 6, such as Figure 1 As shown, when the raw material glass 6 is received, it is all loaded on a pallet, and a number of glasses 6 are stacked on the pallet, with protective paper between two adjacent glasses 6, and the pallet is placed on the glass support placement platform 5 by a forklift or other transport tool. There are sinking pits on the bottom surface below the glass support placement platform 5, and the sinking pit is used to accommodate the lifting mechanism 1 4. The glass support placement platform 5 is fixedly connected to the lifting mechanism 1 4, and rises or falls under the drive of the lifting mechanism 1 4. When the lifting mechanism 1 4 is retracted to the lowest position, the glass support placement platform 5 can be flush with the ground 9, which is convenient for transporting a whole tray of glass 6 to the glass support placement platform 5. A glass grabbing unit 2 is provided above the glass holder placement platform 5. The glass grabbing unit 2 includes a three-way guide rail mechanism and a plurality of glass 6 suction cups, which can reciprocate along the horizontal longitudinal, transverse and vertical directions, and further can reciprocate between the glass holder placement platform 5 and the transmission line 3. There are multiple groups of glass 6 suction cups, and the glass 6 suction cups are connected to an air pump for adsorbing the glass 6 from the upper surface of the glass 6, and further transferring the grasped glass 6 from the glass holder placement platform 5 to the transmission line 3.

[0024] It can be understood that the transmission line 3 includes a conveyor belt, rollers and a motor for driving the conveyor belt to circulate, and a reducer and a controller for controlling the running direction and speed of the conveyor belt.

[0025] In the above embodiment, a paper grabbing unit 1 is also included, which is located obliquely above the glass holder placement platform 5. The paper grabbing unit 1 intermittently moves to the top of the glass 6 and removes the protective paper between two adjacent glasses 6. It should be understood that the paper grabbing unit 1 may include a mechanical arm, a conveyor belt, a sensor and a control system for extracting, transporting and placing protective paper or other film materials. The design of the paper grabbing unit is intended to improve the automatic feeding efficiency of the glass 6, reduce labor costs, and ensure that the glass grabbing unit 2 can smoothly grab a single top layer of glass 6 without dragging or sticking to other glasses 6 during the transfer process.

[0026] In the above embodiment, a sensing device for sensing the height position of the top layer of glass 6 is also provided at a certain height position above the glass holder placement platform 5. The sensing device is electrically connected to the lifting mechanism and is used to automatically sense the height drop of the entire glass holder 6 after the glass grabbing unit 2 grabs the top layer of glass 6, convert the sensing signal into an electrical signal and transmit it to the lifting mechanism. After receiving the electrical signal, the lifting mechanism automatically rises to a height of the thickness of a glass 6 and lifts the next glass 6 to the adsorption position of the suction cup of the glass grabbing unit 2. Therefore, the setting height of the sensing device is the adsorption position of the suction cup, thereby ensuring the smoothness and accuracy of the action of the glass grabbing unit 2.

[0027] Further, in some embodiments, the sensing device is a beam photoelectric sensor, which includes a beam photoelectric transmitting end 7 and a beam photoelectric receiving end 8 arranged at the same height, wherein the beam photoelectric transmitting end 7 specifically includes a transmitter, and the beam photoelectric receiving end 8 includes a receiver, the transmitter is responsible for emitting light, and the receiver is responsible for receiving light. These two parts are usually installed on both sides of the object to be detected to form a light channel. When an object passes through this channel, it will block the light, thereby changing the intensity of the light signal received by the receiver. It should be understood that the transmitter contains a light source, such as a light emitting diode (LED) or a laser diode, which can emit a stable light beam, and the receiver contains a photoelectric conversion element, such as a photodiode or a phototransistor, which can convert the received light signal into an electrical signal. When there is no object blocking it, the light beam emitted by the transmitter can reach the receiver smoothly, and the receiver outputs a high-level signal. Once an object enters the beam path and blocks the light, the light signal received by the receiver weakens or disappears, and a low-level signal is output.

[0028] Furthermore, in some embodiments, one of the opposite photoelectric transmitting end 7 and the opposite photoelectric receiving end 8 is fixedly connected to a side of the transmission line 3 facing the glass holder placement platform 5 .

[0029] In some embodiments, the lifting mechanism includes a cylinder located at the center of the bottom of the glass holder placement platform 5 and auxiliary gas springs located at the four corners of the glass holder placement platform 5 .

[0030] It should be understood that in practical applications, the lifting mechanism is not limited to a cylinder, but can also be an electric cylinder, a lifting motor, a scissor lift, a jacking screw, or other devices or mechanical components capable of linear motion. The specific structure of the lifting mechanism will not be further limited herein.

[0031] Embodiment 2:

[0032] Referring to Figure 2 As shown, Embodiment 2 of the present utility model provides an automatic glass loading device for photovoltaic module production, including a paper grabbing unit 1, a glass grabbing unit 2, a transmission line 3, a glass tray placement platform 5, and a lifting transmission line 10 for transporting glass 6. In this embodiment, the glass tray placement platform 5 is directly fixed at a specified position on the ground 9, and a second lifting mechanism 11 is provided at the bottom of the lifting transmission line 10. The lifting transmission line 10 of course also includes a conveyor belt, rollers and motors for driving the conveyor belt to run in a cycle, as well as a speed reducer and a controller for controlling the running direction and speed of the conveyor belt. The controller is electrically connected to the lifting transmission line 10 and is used to control the lifting and conveying operation of the lifting transmission line 10. Specifically, it realizes the forward running, reverse running, and stop running of the conveyor belt by controlling the operation of the motor and the speed reducer. In practical applications, the second lifting mechanism 11 can adopt the same structure as the first lifting mechanism 4, which will not be elaborated herein. The glass grabbing unit 2 first grabs the glass 6 from the glass tray placement platform 5 and then places it on the lifting transmission line 10 at the first position (bottom position, at this time the second lifting mechanism 11 contracts to the lowest position). The second lifting mechanism 11 operates to lift the lifting transmission line 10 to the second position (top position, at this time the lifting transmission line 10 is at the same height as the transmission line 3 and the ends are adjacent). The controller controls the operation of the motor and the speed reducer to drive the conveyor belt to rotate, and conveys the glass 6 to the transmission line 3 to complete the loading of the glass 6.
