Most parts of my country need heating equipment in winter, and energy consumption in winter is even more serious. In order to reduce energy consumption in winter, people have proposed to use solar heating devices for heating. At present, there are two main types of solar heating equipment in China. One is a solar heater, which mainly consists of a fan and a heat exchanger. The heat exchanger is powered by solar energy to generate heat, and the fan sends out hot air to achieve heating or heating. The second is a solar water heater, which uses solar energy to heat water for indoor heating. Due to various weather factors, the above two solar heating devices cannot meet the heating needs and the user experience is not good. In order to solve the above problems, our company has proposed a solar heating device and a fresh air system, and has developed a modular production solar heating device with a notice number of CN208859908U, so that the above solar heating device is easy to assemble and can improve product quality.

[0093] The following is a detailed description of the automatic assembly process of the solar thermal heating equipment according to the present invention:

[0094] The automatic assembly process of the solar thermal heating equipment starts with the base plate 15 of the solar thermal heating equipment, and uses the base plate 15 as the assembly reference part of the entire assembly process. The assembly of the solar thermal heating equipment is achieved by means of transmission by the transportation system 100, and the streamlined assembly operation is achieved in the form of automatic transmission by the conveying system.

[0095] The automatic assembly process of solar thermal heating equipment includes the following steps:

[0096] 1. Pallet cleaning: The pallet is cleaned manually to remove static electricity.

[0097] (ii) Placing the bottom plate: The bottom plate is placed on the cleaned pallet manually or by a robot.

[0098] (iii) Laying the heat insulation layer and the heat absorption plate: manually laying the heat insulation layer and the heat absorption plate on the bottom plate in sequence;

[0099] (iv) Preliminary framing: First, the release paper of the double-sided adhesive attached to the left, right and rear frames is removed manually, and after applying adhesive, the left, right and rear frames are assembled on the bottom plate using a preliminary framing machine.

[0100] When the image is framed by the preliminary frame assembly machine, the tray 110 stops moving under the action of the stopper 130; under the control of the preliminary main frame assembly machine control system, the front bottom support 021 moves upward to lift the bottom plate 15 placed on the tray 110. At this time, the double-sided adhesive release paper bonded to the left frame 13 and the right frame 14 is manually torn off, and the adhesive is applied to the corresponding places. Then, the left frame 13 and the right frame 14 are manually placed on the corresponding left and right clamping plates. Under the action of the clamp driving mechanism, the upper clamp 332 moves downward to press the corresponding frame ; Then, under the action of the clamping plate driving mechanism, the left frame 13 and the right frame 14 move toward the bottom plate 15, so that the left frame 13 and the right frame 14 are assembled with the bottom plate 15; at this time, the front frame 11 is manually placed on the front clamping plate 253, and the front clamping plate driving mechanism 252 is started to move the front clamping plate 253 backward, pushing the front frame 11 to be assembled with the left frame 13, the right frame 14 and the bottom plate 15. After the assembly, the pressure is maintained for a certain period of time, and then the clamping plates are reset, so that the air duct bin of the rear frame 12 to be assembled is transported to the next process.

[0101] (V) Installing the air duct: Use the air duct installation device to place the air duct in the air duct compartment of the frame to be assembled.

[0102] When the air duct is installed on the device for air installation, the tray 110 stops moving under the action of the blocker 130, and the 3-axis robot sucks up the air duct on the air duct placement rack 03a through the suction cup and puts it into the air duct bin of the rear frame 12 to be assembled, and then the 3-axis robot sucks up the cushion cotton and places it on the cushion cotton placement rack 03b.

[0103] (VI) Installing the rear frame: using a rear frame assembly machine to assemble the rear frame onto the air duct bin to be assembled with the rear frame, so as to form a complete air duct bin.

[0104] When the rear frame assembly machine is used to assemble the rear frame, the tray 110 stops moving under the action of the blocker 130. After the rear base support 041 lifts the air duct bin to be assembled with the rear frame, the front frame positioning mechanism 044 and the clamping plates of the rear frame assembly mechanism 045 move toward the center of the frame to clamp the air duct bin, thereby positioning the air duct bin in the left and right directions. The rear frame is manually placed on the rear clamping plate 451, and the rear clamping plate 451 of the rear frame assembly mechanism 045 pushes the rear frame to be assembled with the left and right frames and the bottom plate. At this time, the front frame positioning mechanism 044 plays a limiting role.

[0105] (VII) Installing the component bin: Install the component bin where components have been installed manually according to the drawings on the air duct bin.

[0106] (VIII) Check the air duct bin and component bin assembled as one; manually check the assembly of the air duct bin, air duct and component bin to ensure product quality.

[0107] (IX) Installing the glass cover: Use the cover installation device to install the glass cover on the opening at the upper end of the air duct compartment.

[0108] When the cover plate installation device assembles the glass cover plate, the 3-axis suction cup manipulator and the correction platform 06a, after the 3-axis suction cup manipulator sucks up the hollow glass cover plate placed on the glass placement rack, due to the high requirement for the position accuracy of the glass cover plate, it is necessary to perform position correction on the correction platform 06a, and then the 3-axis suction cup manipulator sucks up the glass cover plate and places it in the opening at the upper end of the air duct warehouse 1.

[0109] (10) Install the air duct seal strip: manually assemble the air duct seal strip;

[0110] (XI) Installing photovoltaic cover and sealing strip: Manually install the photovoltaic cover on the upper opening of the component bin, and install the sealing strip where sealing is required.

[0111] (XII) Inspecting the assembled solar thermal heating equipment in multiple directions: using the inspection device to grab and turn over the assembled solar thermal heating equipment, and then conduct a full-scale inspection;

[0112] (XIII) Labeling and code scanning: Labeling and code scanning are performed manually;

[0113] (XIV) Offline: The assembled solar thermal heating equipment is transported offline by an offline belt conveyor and packaged.

[0114] A step of manual visual inspection of the appearance is added between step (thirteen) and step (fourteen): the appearance of the assembled solar thermal heating equipment is manually inspected to further ensure product quality.

[0115] Compared with the prior art, the automatic assembly line of solar thermal heating equipment of the present invention can meet the efficient and practical process methods and equipment required for production.
