[0002] A solar collector is a device that converts the sun's radiation into heat. Since solar energy is relatively dispersed, it must be concentrated, so the collector is a key part of various solar energy devices. Due to different uses, collectors and their matching system types are divided into many types, with different names, such as solar cookers for cooking, solar water heaters for producing hot water, solar dryers for drying items, solar furnaces for smelting metals, etc. At present, solar collectors are made of glass, and many of them are rectangular in shape. When the collector is processed and assembled, a frame needs to be installed around the rectangular glass collecting block to facilitate subsequent installation and protection of the collecting glass. When installing the frame, the raw materials need to be transported to a predetermined workbench. Currently, many people have to lift them onto the workbench manually, which results in low work efficiency and heavy workload for workers.

[0019] Example See also Figure 1 , Figure 2 , Figure 3 and Figure 5 The present invention provides a clamping device for assembling a solar thermal collector, including a length adjustment mechanism 100, which is provided with two groups. The two groups of length adjustment mechanisms are symmetrically distributed on both sides of the collector. The specific length adjustment mechanism 100 includes a first mounting plate 110, which is fixed to one end of a support seat 140 by bolts. The first mounting plate 110 is vertically arranged, and a motor 120 is fixed to the outer side of the first mounting plate 110 by bolts. The motor 120 is preferably a servo motor, and the operation of the motor 120 can be automatically controlled by PLC programming, which greatly improves the degree of automation, saves manpower, and improves the processing accuracy. A driving rod 130 is fixed to the end of the output shaft of the motor 120, and the driving rod 130 is arranged inside the support seat 140. A through hole for avoidance is opened in the middle of the support seat 140, and the through hole is rectangular. The driving rod 130 is arranged in the middle of the through hole, crosses the entire through hole, and both ends of the driving rod 130 are rotatably connected to the two sides of the support seat 140. See also Figure 5 , Figure 6 Figure 7 and Figure 8Specifically, the driving rod 130 includes a first screw rod 131 and a second screw rod 132, the first screw rod 131 and the second screw rod 132 are fixedly connected by a connecting shaft 133, the first screw rod 131 and the second screw rod 132 have opposite screw directions, and both ends of the first screw rod 131 and the second screw rod 132 are rotatably connected to both ends of the support seat 140, wherein one end of the first screw rod 131 away from the connecting shaft 133 is fixedly connected to the output shaft end of the motor 120, and the first screw rod 131 and the second screw rod 132 are both threadedly connected to the moving block 150, and the moving block 150 is connected to the moving block 150. 50 is arranged in the through hole of the support seat 140, and the motor 120 drives the first screw 131 and the second screw 132 to rotate, so that the two moving blocks 150 connected thereto move toward each other, that is, the two moving blocks 150 move inwards at the same time, or move outwards at the same time. When the two moving blocks 150 move inwards at the same time, the distance between the two moving blocks 150 decreases, and a product with a shorter length can be transported. On the contrary, when the two moving blocks 150 move outwards at the same time, the distance between the two moving blocks 150 increases, and a product with a longer length can be transported, which greatly improves the mobility and flexibility of the device and improves the work efficiency. See also Figure 6 , Figure 7 and Figure 8 Specifically, first sliders 151 are fixed in the middle of both sides of the moving block 150, and first slide grooves 141 are opened on the side walls on both sides of the through hole of the support seat 140. The first sliders 151 can be accommodated in the first slide grooves 141 and can slide back and forth in the first slide grooves 141. The moving block 150 slides in the through hole along the first slide grooves 141 driven by the first sliders 151, which plays a role in guiding and positioning the moving block 150, reducing the friction resistance between the moving block 150 and the support seat 140, and saving energy and reducing emissions.

[0020] See also Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8It should be noted that a clamping mechanism 200 is provided on each moving block 150. The clamping mechanism 200 is a finger cylinder 210. The finger cylinder 210 is fixed to the lower side of the moving block 150 by bolts. The clamping claws of the finger cylinder 210 are opened and closed to realize the loosening and clamping of the solar thermal collector, which is convenient for its transportation and handling. It should be noted that a protective cover 220 is fixed on the outer side of the opposite side of the clamping claws of the finger cylinder 210. The protective cover 220 is made of rubber material. The rubber material is relatively soft and will not clamp The protective cover 220 will not scratch the surface of the collector, and the rubber material generates a large friction force. The clamping jaws will not slide when clamping the collector, and the safety is greatly improved. The protective cover 220 can contact the outer surface of the solar thermal collector, and the clamping is safer and more reliable. In addition, a circular chamfer 221 is provided at the end of the protective cover 220, and the circular chamfer 221 covers the edges and corners of the front end of the clamping jaws. At this time, when the clamping jaws clamp the collector, the circular chamfer of the protective cover 220 on the clamping jaws contacts the collector, which effectively prevents the edges and corners of the clamping jaws from scratching the collector surface and plays a protective role.

[0021] See also Figure 3 , Figure 4 , Fig. 9 and Fig.10 In addition, a lifting mechanism 300 is provided on the support seat 140, and the lifting mechanism 300 includes a second mounting plate 310, and a driving member 320 is fixed to the second mounting plate 310 by bolts. The driving member 320 can be a cylinder, an electric push rod, a hydraulic cylinder, etc., and a connecting frame 330 is fixed to the piston rod end of the driving member 320. The connecting frame 330 is a cross-shaped arrangement, and the four corners of the connecting frame 330 are fixedly connected to the end of the support seat 140, so as to realize the connection and fixation of the support seat 140. The connecting frame 330 drives the support seat 140 to move up and down through the driving member 320, and then the support seat 140 can drive the clamping mechanism 200 to move up and down, so as to realize the upward transportation of the collector; See also Figure 3 , Fig. 9 and Fig.10 The limit block 332 is set on the upper end of the guide rod 331, and the limit block 332 is set above the second mounting plate 310. When the connecting frame 330 moves downward, the guide rod 331 also moves downward until the limit block 332 conflicts with the upper side of the second mounting plate 310, and the limit block 332 stops moving, and then the guide rod 331 also stops moving downward, so that the entire connecting frame 330 also stops moving downward. The setting of the limit block 332 prevents the guide rod 331 from sliding out of the second mounting plate 310 when sliding downward, thereby playing a limiting and protective role.

[0022] See also Fig. 9 and Fig.10 In addition, a support frame 410 is arranged on the lower side of the second mounting plate 310, and a second slide groove 411 is opened on the support frame 410. A second slider 311 is slidably connected in the second slide groove 411. The second slider 311 is fixedly installed under the second mounting plate 310. The second mounting plate 310 can slide back and forth on the support frame 410 under the traction of a traction mechanism (not shown in the figure), thereby realizing the horizontal transportation and movement of the collector.

[0023] Working principle: First, the motor 120 is started, and then the motor 120 drives the driving rod 130 to rotate, and the first screw 131 and the second screw 132 on the driving rod 130 rotate in the same direction and at the same speed. Since the first screw 131 and the second screw 132 have opposite screw directions, the moving blocks 150 on the first screw 131 and the second screw 132 move outward or inward at the same time, and the distance between the two moving blocks 150 is selected according to the length of the collector; When the two moving blocks 150 on both sides of the collector move to the inner edge, the finger cylinder 210 works, and then the finger cylinder 210 clamps the upper and lower surfaces of the collector, thereby achieving clamping and fixing of the collector; Then the piston rod of the driving member 320 moves upward, and then the piston rod drives the connecting frame 330 to move upward, and then the connecting frame 330 drives the support seat 140 to move upward, and then the support seat 140 drives the finger cylinder 210 to move upward, and then the finger cylinder 210 drives the collector to move upward, and then the collector leaves the workbench, and after moving upward to the predetermined position, the traction mechanism pulls the second mounting plate 310 to move backward on the support frame 410, and then drives the collector to move backward, realizing the transportation and handling of the collector. The whole process does not require manual operation, but is completely completed by electrical automation, which greatly improves work efficiency, greatly reduces the workload of workers, and improves safety.

[0024] It should be noted that the motion state and motion trajectory of each mechanism of the device can be automatically controlled by numerical control programs or PLC programming, and automatic start and stop and automatic operation can be achieved in conjunction with position switches. The above-mentioned programs and programming are common knowledge known to those skilled in the art, so they will not be described in detail here; The specific models and specifications of the motor 120, finger cylinder 210 and driving member 320 need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0025] The power supply and principle of the motor 120, the finger cylinder 210 and the driving member 320 are clear to those skilled in the art and will not be described in detail here.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
